TECHNICAL FIELD
[001] The present invention relates to a laminated composite interior component and more specifically to a technique for further improving the feel of a laminated composite interior component in which the damping characteristics are imparted through elastic deformation of multiple protrusions. BACKGROUND OF THE TECHNIQUE
[002] There is a known laminated composite interior component that includes: (a) a first member having a predetermined conjugated surface surface; and (b) a second member produced from an elastically deformable resin material, the second member having a part similar to the plate which is substantially parallel to the conjugated surface and which has multiple protuberances which are integrally formed with the part similar to the plate and that protrudes towards the conjugated surface so that a space is formed between the conjugated surface and the part similar to the plate, the second member being arranged so as to be laminated on the first member with the protuberances in contact with the conjugate surface, where (c) damping characteristics are imparted to the laminated composite interior component when distal ends of the protuberances are pressed against the conjugated surface and thus elastically deformed. A component described in Patent Document 1 is an example of the laminated composite interior component and refers to an interior component (armrest, or the like) for a vehicle. Patent Document 1 describes a technique for improving the feel (smooth feel) of a padding member, which is the second member, through elastic deformation of multiple pin-shaped protuberances formed on the back face of the padding member. Patent Document 1 also describes a technique in which ribs are formed instead of pin-shaped protuberances. RELATED TECHNICAL DOCUMENT PATENT DOCUMENT
[003] [Patent Document 1] Publication of Patent Application No. JP 2003-103676 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION
[004] However, in such a conventional laminated composite interior component, only columnar protuberances are formed. Therefore, a way of deformation (direction of bending, or similar) at the moment when the protrusions are elastically deformed by a pressing load is not stable, which causes a problem that the feel of the laminated composite interior component is likely to vary. When ribs are formed instead of multiple bulges, the stiffness becomes high, which makes it difficult to get a smooth enough sensation.

[0017] The thirteenth invention provides the laminated composite interior component mentioned in the eleventh or eleventh invention, in which an entrance door to introduce a heat medium that is supplied with air conditioning to a space between the base member and the member surface is provided in the base member and the heat medium is supplied in space.
[0018] The fourteenth invention provides the laminated composite interior component mentioned in the eleventh or eleventh invention, in which (a) the surface member is laminated to the base member in order to hermetically seal the space between the surface member and member base is fixedly attached to the base member; and (b) the compressed gas is filled in space and the plate-like part of the surface member is driven by the compressed gas. EFFECT OF THE INVENTION
[0019] In such a laminated composite interior component, the plate-like part is dotted with multiple protuberances and the flexural rigidity of each protuberance against a compression load is anisotropic around the geometric axis of the protuberance. Therefore, each protuberance is easily flexed and deformed in a specific direction determined by anisotropy and the smooth sensation (damping characteristic) improves. In addition, it is possible to control the flexion (tipping) direction of each protuberance. Therefore, the way of deformation (direction of flexion, or similar) at the moment when each protuberance is elastically deformed becomes stable and variations in sensation at the moment when the protuberances are pressed with a finger or hand are suppressed.
[0020] In addition, the protrusions are arranged in such locations so as to form the respective sides of each of the multiple polygons so that there is the lattice pattern formed in which multiple polygons are arranged consecutively adjacent to each other. Therefore, the multiple bulges are formed in a uniform disposition pattern and variations in sensation at the time when the bulges are pressed with a finger or a hand are suppressed. When the positions of the protrusions are offset from each other according to the respective sides in the lattice pattern, the flexion directions of the protrusions accordingly vary. Therefore, a sensation of appropriate stiffness (soft feeling not excessive) is obtained for the reason that the lumps support each other. Therefore, it is possible to obtain an additionally excellent sensation due to a combination of the appropriate rigid sensation and the soft sensation is obtained through elastic deformation of the bulges.
[0021] The fourth invention is the case that each of the multiple protuberances is configured to be flexed and deformed in a certain direction about its geometric axis. In the lattice pattern that is formed by repeatedly repeating polygons that have the same quadrangular shape or the same hexagonal shape, the protuberances are arranged on the respective sides of each of the polygons so that each side has one of the protuberances and a direction of flexion of each of the protrusions either an inward direction or an outward direction in relation to a corresponding polygon and the protuberances are arranged in such positions that the flexion directions of the protuberances are alternately reversed around a center line of a corresponding polygon. Therefore, the manner of deformation of the protuberances in the polygon unit is substantially the same in the entire region regardless of the fact that each protuberance is configured to be flexed and deformed in a certain direction about its geometric axis. Accordingly, a uniform sensation is obtained.
[0022] The fifth invention is the case that the lattice pattern that is formed by the multiple protuberances is a honeycomb pattern formed by repeating consecutively regular hexagons that are uniform in size, with hexagons being used as the polygons. For example, when the positions of the protrusions are offset from each other by 60 ° or 120 ° according to the respective sides in the regular hexagons, the anisotropy of the elastic deformation against a pressing load is suppressed compared to a square lattice pattern. Therefore, a uniform sensation is obtained even against a pressing load applied in an oblique direction.
[0023] In the sixth invention, the vertical cross section at a specific position around the geometric axis of each protuberance is an asymmetric shape. Therefore, each protuberance is always elastically deformed in a uniform deformation manner, variations in sensation are suppressed and the same sensation is substantially obtained in a stable manner. In addition, it is possible to control the flexion direction (tipping) and the ease of flexing the protuberances at the base of the cross-section with an asymmetrical shape. Therefore, by arranging the protrusions so that the protrusions do not make contact with each other at the moment of flexion deformation, it is possible to reliably obtain a predetermined smooth sensation.
[0024] In the seventh invention, a pair of side walls, the side walls being on respective sides in the vertical cross section, has a widely inclined surface that is tilted inwards by a greater proportion than the other side wall. Therefore, each protuberance is easily flexed in the direction of the side opposite the side on which the widely inclined surface is formed. Accordingly, it is possible to further improve the smooth sensation obtained through the elastic deformation of the protuberances. In addition, by controlling the ease in flexing each protuberance by changing the angle and range of the inclination of the widely inclined surface, it is possible to easily adjust the smooth feel. In addition, it is possible to control the direction of bending at the base of the position at which the widely inclined surface is formed. Therefore, by arranging the protrusions so that the protrusions do not make contact with each other at the moment of flexion deformation, the protrusions are arranged as densely as possible. In this way, it is possible to reliably obtain a predetermined smooth sensation through elastic deformation while variations in sensation are suppressed due to the presence or absence of the protuberances.
[0025] The eighth invention is the case that a corner shape of a base part of each of the protrusions, in which the protrusion projects from the part similar to the plate, varies around the geometric axis of the protrusion. For the reason that each protrusion is easily flexed and deformed in a specific direction determined by the shape of the corner, the way of deformation at the moment when each protuberance is elastically deformed becomes stable and variations in sensation at the moment when the protuberances are pressed with a finger or a hand is suppressed. In addition, it is possible to control the flexion direction (tipping) and the ease in flexing the protuberances on the basis of variations in the shape of the corner.
[0026] Therefore, by arranging the protrusions so that the protrusions do not make contact with each other at the moment of flexion deformation, the protrusions are arranged as densely as possible. In this way, it is possible to reliably obtain a predetermined smooth sensation through elastic deformation while variations in sensation are suppressed due to the presence or absence of the protuberances.
[0027] The ninth invention is the case where the material of each of the protrusions varies around the geometric axis of the protrusion. Because each protrusion is easily flexed in a specific direction determined by the material, the way of deformation at the time when each protrusion is elastically deformed becomes stable and variations in sensation at the time when the protuberances are pressed with a finger or hand are suppressed. In addition, it is possible to control the flexion direction (tipping) and the ease in flexing the protuberances on the basis of variations in the material. Therefore, by arranging the protrusions so that the protrusions do not make contact with each other at the moment of flexion deformation, the protrusions are arranged as densely as possible. In this way, it is possible to reliably obtain a predetermined smooth sensation through elastic deformation while variations in sensation are suppressed due to the presence and absence of protuberances.
[0028] The tenth invention is the case that the laminated composite interior component is a panel component similar to the board. In the same, the second member is a surface member; the first member is a base member similar to the plate that is harder than the second member; and the surface member is arranged to be laminated to the surface of the base member and is fixedly engaged with the base member. In the panel component configured in this way, when the plate-like part of the surface member is pressed with a finger or hand, an excellent sensation is obtained through the elastic deformation of the protuberances of the surface member. In this way, advantageous effects in the first to ninth inventions are obtained in an appropriate manner. When the surface member is produced from a two-layer structure that has only the first member and the second member, it is possible to eliminate the cost of manufacture.
[0029] The eleventh invention is the case that an upholstery member is fixedly attached to the surface member in the panel component recited in the eleventh invention. The surface of the plate-like part, the surface being on the side opposite the side where the protuberances are formed, is covered with the padding member. Therefore, even if there is a sunken mark, irregular polishing, or similar in the part similar to the plate due to the protuberances, the sunken mark, irregular polishing, or similar, is not exposed on the outside and damage to the surface member is avoided. . Therefore, the range of choices for the resin material of the enlarged surface member and the design flexibility in the shape, or similar, of each protuberance in association with the sensation increases. Therefore, it is possible to additionally adjust the sensation easily and appropriately.
[0030] The twelfth invention is the case that the laminated composite interior component is a panel component similar to the board. In it, the first member is a member of surface similar to the plate produced from a soft material of elastically deformable resin; and the second member is fixedly attached to a base member similar to the plate so that a back face of the plate-like part, the rear side being on the opposite side to the side where the protuberances are formed, is in close contact with the base member similar to the plate. In the panel component configured in this way, when the surface member (first member) is pressed with a finger or a hand, the back face (mating surface) of the surface member is pressed against the distal ends of the protuberances of the second member. Therefore, an excellent sensation is obtained through elastic deformation of the protuberances. In this way, advantageous effects in the first to ninth inventions are appropriately obtained. The second member that has the protuberances is covered with the surface member (first member) and the part similar to the second member plate is attached to the base member. Therefore, even when there is a sunken mark, an irregular polishing, or similar, on the surface of the part similar to the plate, the surface being on the side opposite the side where the protuberances are formed, the sunken mark, the irregular polishing, or similar, it is not exposed outside. In this way, the range of choices for the second limb resin material is extended and the design flexibility in the shape, or similar, of each protuberance in association with the sensation increases. Therefore, it is possible to additionally adjust the sensation easily and appropriately.
[0031] In the thirteenth invention, an entrance door is provided in the base member (first member) and is supplied with an air conditioning heat medium for a space between the base member and the surface member (second member) ). Therefore, it is possible to adjust the temperature by means of heat, which in this way further improves the feel of the plate-like part of the surface member.
[0032] In the fourteenth invention, compressed gas is filled in the space between the base member (first member) and the surface member (second member), and the plate-like part of the surface member is driven by the compressed gas. Therefore, it is possible to give an appropriate rigid sensation to parts other than the bulges, which in this way further improves the sensation. BRIEF DESCRIPTION OF THE DRAWINGS

[0093] The invention is applied to vehicle interior components, such as a door finish, a luggage side finish and an instrument panel and ornaments and the like, which are attached to the interior components. Alternatively, the invention can also be applied to panel components other than components for a vehicle. The invention can be applied not only to the panel-like panel component but also to a solid component formed by laminating a second member on the surface of a first member or a base member, which has a three-dimensional curved solid shape. When the first member is used as a base member, relatively hard synthetic resin materials, such as non-plasticized polyvinyl chloride, polypropylene, polyethylene and ABS, are preferably used. Alternatively, the first member can be produced from another material, such as metal. As the resin material for the first member when used as a surface member or as the resin material for the second member, various thermoplastic resins, such as plasticized polyvinyl chloride, a styrene resin, an olefin resin and a resin polyester, are preferably used. As the material for an upholstery member, not only various thermoplastic resins, such as plasticized polyvinyl chloride, a styrene resin, an olefin resin and a polyester resin, but also various upholstery materials, such as fabric, non-woven fabric , knitted fabric, vinyl chloride and a flexible film can be used.
[0094] Each of the protuberances that have an elongated shape in a plan view in the second invention is formed, for example, in a rectangular shape in the plan view. Alternatively, each of the protuberances as a whole can be formed in several elongated shapes such as a curved circular arc shape and a crank shape. Each of the protrusions is arranged, for example, in such a position that the longitudinal direction of the protrusion is substantially parallel to a corresponding side of each of the polygons that constitute a lattice pattern. Each protrusion preferably has a tapered shape so that the cross-sectional area decreases towards the distal end. The height H of each protuberance is preferably within the range of, for example, approximately 2 mm <H <approximately 4 mm. The width d of each rectangular protrusion in a direction perpendicular to its longitudinal direction is preferably within a range of, for example, approximately 1 mm <d <approximately 2 mm and the length L of each rectangular protrusion in the longitudinal direction is preferably within of the range of approximately 1.5 mm <L <approximately 2.5 mm.
[0095] The lattice pattern, in which the protuberances described above are arranged, is formed so that, for example, the same equilateral triangles, the same squares or the same regular hexagons, which are used as the polygons, are repeated consecutively . Alternatively, the lattice pattern can be a lattice pattern in which rectangles, rhombuses, parallelograms, scalene triangles, scalene hexagons, or the like are repeated consecutively. Additionally alternatively, the lattice pattern can be a lattice pattern in which a plurality of polygon types are repeated regularly or a lattice pattern in which a plurality of polygon types are irregularly arranged adjacent to each other. That is, several types of lattice patterns can be employed.
[0096] Preferably, a protuberance is arranged on each side of each polygon. Alternatively, two or more protuberances can be arranged on each side of each polygon. In the case of a rectangle or parallelogram, where the lengths of the sides of each polygon are different from each other, the number of protrusions can be different between a long side and a short side. Each protuberance is arranged, for example, in such a position that its longitudinal direction is parallel to a corresponding side of each polygon. Alternatively, each protuberance can be arranged in such a position that its longitudinal direction is perpendicular to a corresponding side or it can be arranged in such an inclined position that its longitudinal direction is inclined at a predetermined angle with respect to a corresponding side. The longitudinal direction of each protuberance can be parallel to or perpendicular to a corresponding side, depending on a location where the protuberance is arranged in the lattice pattern.
[0097] Each of the protrusions in the second invention is formed so that a vertical cross-section perpendicular to the longitudinal direction of the protrusion has, for example, an asymmetrical shape as in the sixth invention, or is formed to have a widely inclined surface with na seventh invention. Alternatively, each of the protrusions can be formed so that a vertical cross-section perpendicular to the longitudinal direction of the protrusion has a symmetrical shape. With the asymmetric shape in the sixth invention, the protrusions are elastically deformed in a uniform deformation manner. For example, as in the seventh invention, the inclinations of the side walls on respective sides in the vertical cross section are different from each other. Note that, not only the configuration in which the inclinations are different along the entire lengths of the side walls, but also, for example, the configuration in which the inclinations are partially different, for example, in parts on the distal end side of the protuberance can be employed. In addition, when each protrusion projects obliquely so as to be inclined in a normal direction for the part similar to the plate, the vertical cross-section perpendicular to the longitudinal direction has an asymmetrical shape and each protrusion is easily flexed in the direction inclined. Apart from the configuration in which each protuberance is flexed and deformed in the direction of one side in a direction perpendicular to the longitudinal direction, a configuration in which each protuberance is elastically deformed in order to be twisted in a certain direction about its center line. be employed as a modified mode. The widely inclined surface in the seventh invention preferably has an angle of inclination Y of, for example, approximately 15 ° to approximately 60 ° with respect to the normal direction and the angle of inclination y most preferably is within the range of approximately 20 ° to approximately 50 °.
[0098] The sixth invention and the seventh invention are not limited to the case where the shape of a plan view (lateral cross section) is an elongated shape. The shape in a flat view can be a circular shape, a semicircular shape, a square shape, a trapezoid shape, or the like. In the eighth invention in which the corner shape of the base part of each protuberance varies around the geometric axis of the protuberance or the ninth invention in which the material of each protuberance varies around the geometric axis of the protuberance, the shape in a plan view it can be an elongated shape or it can be a circular shape, a semicircular shape, a square shape, a trapezoidal shape, or the like. Therefore, several modes are employed. The asymmetric shapes in the sixth invention and the seventh invention, the variation in the corner shape in the eighth invention and the variation in the material in the ninth invention each can be implanted only to grant anisotropy to the flexural stiffness. Alternatively, two or more of them have been combined with each other to provide anisotropy to the flexural stiffness.
[0099] The lattice pattern in the fifth invention is a honeycomb pattern in which regular hexagons are repeated consecutively. For example, when the shape of each protrusion in a plan view is a rectangular shape, the protrusion is arranged in such a position that its longitudinal direction is parallel to a corresponding side of each regular hexagon. The spacing P between two parallel sides of each regular hexagon (distance between the centers of the protuberances arranged on both sides) is preferably within the range of 3.5 mm <P <7.5 mm and more preferably within the range of 4 mm <P <7 mm. In the case of P <3.5 mm, each protrusion is small and the formability deteriorates. In the case of P> 7.5 mm, a difference in the reaction force due to the presence or absence of the protuberance (difference in reaction force enters a location where the protuberance is arranged and a location between the protuberances) becomes wide and a uncomfortable feeling is provided depending on the material or thickness of the board-like part. Each protuberance that has an elongated shape in a plan view can be arranged in such a position that its longitudinal direction is perpendicular to a corresponding side of each regular hexagon or in such an inclined position that its longitudinal direction is inclined with respect to a corresponding side of each regular hexagon. This also applies to lattice patterns other than the lattice pattern formed from regular hexagons.
[00100] When the fourth invention and fifth invention are implanted, not only protrusions that have an elongated shape in a plan view, but also protuberances that have a square shape in a plan view, a circular shape in a plan view, a shape semicircular in a flat view, a trapezoidal shape in a flat view, or similar, can be used. For example, it is possible to control the direction of bending by forming a widely inclined surface that has an angle of inclination Y of approximately 15 ° to approximately 60 °. As in the eighth invention and the ninth invention, it is possible to control the bending direction by varying the corner shape or material. In that case, the departure P from the honeycomb pattern in the fifth invention preferably falls within, for example, a range of approximately 3.5 mm to approximately 7.5 mm. The appropriate height H of each protrusion is preferably within a range of approximately 2 mm to approximately 4 mm, and each of the longitudinal and lateral dimensions of each base end is preferably within the range of approximately 1 mm to approximately 3 mm.
[00101] Each protuberance of the eighth invention is formed so that anisotropy is granted to the protuberance by varying the corner shape of the base part, in which the protuberance protrudes from the part similar to the plate, around the geometric axis of the protuberance. For example, by forming a groove near the base, the protrusion easily falls towards the side where the groove is formed. A cutout can be formed at the base of each protrusion. By varying the radius r of the corner on which the protrusion projects from the part similar to the plate to make radius r on one side wider than that on the opposite side, the protrusion easily falls in the direction of the opposite side. A linear inclined portion may be formed on the corner portion.
[00102] Each protuberance of the ninth invention is formed so that anisotropy is granted to the protuberance by varying the material of the protuberance around its geometric axis. By combining synthetic resin materials that have different hardnesses with each other, the protrusion easily falls over the side where the material that has a lower hardness is provided. The variation in material can be provided, for example, using different materials for two regions obtained by equally dividing each protuberance around its geometric axis, using different materials for regions obtained by dividing each protuberance equally to have , for example, 120 °, and the remainder or using different materials for regions obtained by dividing each protuberance unevenly in a position offset from its geometric axis. That is, several modes can be used.
[00103] In terms of improving the smooth feel, preferably, the multiple protuberances formed so as to be spread over the part similar to the plate are arranged at predetermined intervals at the base of the height of each protuberance so as not to make contact with each other at the moment of flexion deformation. However, for example, the multiple protrusions can be arranged so that the protrusions make contact with each other at a predetermined deformation stage.
[00104] In the twelfth invention, the first member is a surface member, and the second member is fixedly attached to a plate-like base member and at least one three-layer structure including the base member is formed . Alternatively, a four-layer structure can be formed by providing an upholstery member on the surface member.
[00105] As for a heat medium in the thirteenth invention or compressed gas in the thirteenth invention, air is preferably used. However, a non-air gas can be used and a liquid, such as water, can be used as the heat medium. To implement another invention, the heat medium does not need to be supplied to the space between the first member and the second member or the compressed gas does not need to be filled in the space between the first member and the second member. It is only necessary to hermetically seal the space or the space can be communicate with the atmosphere. The thirteenth invention and the fourteenth invention refer to the case where the first member is the base member and the second member is the surface member. However, even in the case of the twelfth invention in which the first member is the surface member and the second member is attached to the base member, a similar configuration can be employed. The heat medium can be introduced from an air conditioner by providing an inlet port on the second member and the base member or the surface member (first member) can be driven by the compressed gas. MODALITIES
[00106] Hereinafter, modalities of the invention will be described in detail with reference to the drawings. Figure 1 is a schematic view showing a shoulder part (lower end of a window) of an upper end of a vehicle door finish 12 that has an ornament 10 to which the invention is applied and is a front view when viewed from the side of a decorative surface of a door on the right side of a vehicle, that is, the interior side of the vehicle.
[00107] Figure 2 is a view showing only ornament 10 in Figure 1 and a perspective view of multiple small protuberances 20 (see Figure 6, for example) formed on the back face of a surface member 16, when viewed on the side of the decorative surface. Figure 3 is a view showing a base member 14 of the ornament 10 with a surface member 16 removed. Figure 4 is a cross-sectional view of ornament 10, taken along line IV-IV in Figure 1. Figure 5 is a cross-sectional view of ornament 10, taken along line V-V in Figure 1.
[00108] The ornament 10 is a laminated component which is formed from the base member similar to plate 14 and the surface member 16 arranged to be laminated on a surface 22 of the base member 14 substantially parallel to the surface 22 of the member base.
[00109] The ornament 10 corresponds to a panel similar to the plate and the surface 22 of the base member 14 corresponds to a conjugated surface. The surface member 16 is a second member and is a one-piece member produced from a relatively soft elastic deformable synthetic resin material, such as plasticized polyvinyl chloride. The surface member 16 has a part similar to the plate 18 which is substantially parallel to the surface 22 and the multiple small protuberances 20 projecting towards the surface 22 of the base member 14 are formed integrally with the rear face of the part similar to plate 18. Wrapping the outer peripheral end parts 26 of the part similar to the plate 18 around the outer peripheral edge parts of the base member 14 with a space 24 formed between the part similar to the plate 18 and the surface 22 due to small protuberances 20 and distal ends of the small protuberances 20 in close contact with the surface 22, the surface member 16 is fixedly engaged in the base member 14. The small protuberances 20 correspond to the protuberances.
[00110] The base member 14 corresponds to the first member. The base member 14 is a one-piece member produced from a synthetic resin material, such as polypropylene, which is harder than the surface member 16 and end parts 26 are engaged with a plurality of engagement protrusions. 28 formed in the outer peripheral edge parts of the back face. A plurality of interlocking hitch parts 30 are integrally formed with the back face of the base member 14 and the ornament 10 is fixedly engaged in the vehicle door finish 12 by means of the interlocking hitch parts 30. In a state where the ornament 10 is fixedly attached to the vehicle door finish 12 by means of the locking engagement parts 30 as described above, the end parts 26 are pressed against the outer peripheral edge parts of the base member 14 by a plurality of pressing parts 32 provided in the vehicle door finish 12 and a state where the end parts 26 are wrapped around the outer peripheral edge parts is maintained. The end parts 26 can be attached to the peripheral edge parts of the base member 14 by other means of attachment, such as an adhesive agent.
[00111] Figure 6 is a view illustrating the multiple small protrusions 20 formed on the back face of surface member 16. Figure 6 (a) is a plan view showing the small protrusions 20 in a state where the size of each small protuberance 20 is close to an actual size (diameter = 50 mm), and Figure 6 (b) is an enlarged plan view showing part VIb in Figure 6 (a). These plan views each show a state when viewed from a normal direction for the part similar to plate 18. Figure 7 is a vertical cross-sectional view taken along line VIIVII in Figure 6 (b). Figure 8 is a vertical cross-sectional view taken along the line in Figure 6 (b). As is apparent from these drawings, the multiple small protuberances 20 have the same shape and have an elongated shape (rectangular shape in the present modality) in a flat view (in a state in Figure 6) when viewed from the normal direction to the part similar to the plate 18, and each of the multiple small protrusions 20 is arranged in such a location to constitute a corresponding side of one of the multiple polygons and in such a position that the side is substantially parallel to the longitudinal direction of the small protrusion 20, so that there is a pattern lattice 34 formed in which each side of each of the multiple polygons having the same shape overlaps a corresponding side of the sides of an adjacent polygon of the multiple polygons. In the present embodiment, the shape of each small protrusion 20 in a plane view is a rectangular shape of which four corners are rounded and each small protrusion 20 is arranged in such a position that the longitudinal direction of the same coincides with the corresponding side of one of the polygons . As indicated by the alternating two short and long lines in Figure 6 (b), the lattice pattern 34 is a honeycomb pattern in which regular hexagons that are uniform in size, which are used as the polygons, are repeated consecutively and a small protuberance 20 is arranged in the center part of each side of each of the regular hexagons.
[00112] As is apparent from Figure 7 and Figure 8, each small protuberance 20 has a delicately tapered shape so that the cross-sectional area decreases towards its distal end side. The vertical cross-sectional shape in the width direction perpendicular to the longitudinal direction, shown in Figure 7, and the vertical cross-sectional shape in the longitudinal direction, shown in Figure 8, each have a symmetrical shape in relation to a neutral plane that is normal for the part similar to plate 18 and the peripheral parts of the distal end (both end parts of the cross-sectional shape) are rounded. The small protuberances 20 will be further described in a specific way. A spacing P which is a distance between the two parallel sides of each of the regular hexagons that make up the lattice pattern 34, that is, a distance between the centers of the small protuberances 20 arranged on these two sides, is within a range of 4 mm <P <7 mm and is approximately 5 mm in the present mode. A height H of each small protuberance 20 is within a range of 2 mm <H <3.5 mm and is approximately 2.5 mm in the present embodiment. A width d of each small protuberance 20 is within the range of 1 mm <d <2 mm, and is approximately 1.2 mm in the present embodiment. A length L of each small protuberance 20 is within a range of 1.5 mm <L <2.5 mm and is wider than the width d and is approximately 1.8 mm in the present embodiment. A slope angle α of each of the side walls on the respective sides of each small protuberance 20 in the width direction is within a range of 2 ° <α <5 °, and is approximately 3 ° in the present embodiment. A slope angle β of each of both end peripheries of each small protuberance 20 in the longitudinal direction is within a range of 10 ° to 15 ° and is approximately 13 ° in the present embodiment. A thickness t of the part similar to the plate 18 is within a range of 1 mm <t <2 mm, and is approximately 1.5 mm in the present embodiment. These dimensions and angles are appropriately established taking into account the material and the like, of the surface member 16 so that a predetermined sensation (soft sensation, rigid sensation, or the like), strength and the like is obtained.
[00113] In the ornament configured 10 in this way, when the plate-like part 18 of the surface member 16 is pressed with a finger or a hand, the distal ends of the small protuberances 20 are pressed against the surface 22 of the base member 14 and they are elastically deformed. In this way, damping characteristics are granted and the predetermined sensation is obtained. In the present embodiment, each of the multiple small protuberances 20 has a symmetrical shape. Therefore, when a pressing load is applied to the part similar to plate 18 from the normal direction to the part similar to plate 18, basically the small protuberances 20 are compressed and deformed in the top-down direction in Figure 7 and Figure 8, so that damping characteristics are granted. When a pressing load is applied obliquely to the part similar to the plate 18, the small protuberances 20 are not only compressed and deformed in the direction from top to bottom, but also flexed and deformed in a direction (lateral direction in Figure 7) perpendicular to the longitudinal direction, so that damping characteristics are granted. In each small protuberance 20, the flexural stiffness in the width direction (lateral direction in Figure 7) perpendicular to the longitudinal direction is less than that in the lateral direction in Figure 8, which is the longitudinal direction and, therefore, the flexural stiffness against a compression load is anisotropic around the geometric axis of the small protuberance 20.
[00114] As described above, in the present embodiment, the part similar to plate 18 is dotted with multiple small protrusions 20 and the flexural stiffness of each small protrusion 20 against a compression load is anisotropic around the geometric axis of the small protrusion 20. Therefore, each small protuberance 20 is easily flexed and deformed in a specific direction determined by anisotropy and the smooth sensation improves. That is, for the reason that each small protuberance 20 according to the present embodiment has an elongated shape in a flat view, each small protuberance 20 is easily flexed and deformed in the width direction perpendicular to the longitudinal direction and the smooth feeling improves.
[00115] Furthermore, it is possible to control the flexion direction of each small protuberance 20. Therefore, the way of deformation (flexion direction, or similar) at the moment when each small protuberance 20 is elastically deformed becomes stable, and variations in sensation at the moment when the small bumps 20 are pressed with a finger or a hand are suppressed.
[00116] The small protuberances 20 are arranged at such locations to form the respective sides of each of the multiple polygons so that there is the lattice pattern 34 formed in which multiple polygons are arranged consecutively adjacent to each other. Therefore, the multiple small protuberances 20 are formed in a uniform disposition pattern, and variations in sensation at the time when the small protuberances 20 are pressed with a finger or hand are suppressed.
[00117] The positions of the small protrusions 20 are offset from each other by a predetermined angle (60 ° in the present embodiment) according to the respective sides in the lattice pattern 34. Accordingly, the bending directions of the small protrusions 20 vary. Therefore, an appropriate rigid sensation (soft sensation not excessive) is obtained for the reason that the small protuberances 20 support each other. Therefore, it is possible to obtain an excellent sensation due to a combination of the rigid sensation and the appropriate soft sensation that is obtained through elastic deformation of the small protuberances 20.
[00118] The lattice pattern 34 is a honeycomb pattern in which regular hexagons, which are used as the polygons, are repeated consecutively and the positions of the small protuberances 20 that have an elongated shape are offset from each other by 60 ° . Therefore, the elastic deformation anisotropy against a pressing load is suppressed in comparison with, for example, a square lattice pattern in which the positions of the small protuberances 20 are offset by one another by 90 °. Therefore, a uniform sensation is obtained even against a pressing load applied in an oblique direction.
[00119] In the present embodiment, only the surface member 16 is laminated and fixedly attached to the base member 14 to form the ornament 10 which has a two-layer structure. Therefore, it is possible to manufacture ornament 10 at a low cost.
[00120] In the present embodiment, the shape of each of the multiple small protuberances 20 in a flat view is a simple rectangular shape. Therefore, the structure of a molding matrix that is used to mold the surface member 16 that has the small protuberances 20 is simple. As a result, it is possible to reduce the cost of manufacture and form the structure at a low cost.
[00121] Next, another embodiment of the invention will be described. Note that, in the modality described below, substantially the same parts as those in the modality described above will be denoted by at least reference numerals than those in the modality described above and their detailed description will be omitted.
[00122] Figure 9 is an enlarged plan view that corresponds to Figure 6 (b). A surface member 40 is different from surface member 16 in the shape of each small protuberance 42.
[00123] Figure 10 is an enlarged vertical cross-sectional view taken along line X-X in Figure 9.
[00124] Figure 11 is an enlarged vertical cross-sectional view taken along line XI-XI in Figure 9. As is apparent from these drawings, the present modality and the modality described above are the same in which each of the multiple small protuberances 42 have an elongated shape in a plan view (in a state in Figure 9) when viewed from a normal direction for the part similar to plate 18, and are arranged in such a location as to constitute a corresponding side of each of the regular hexagons that make up the lattice pattern 34 which is the honeycomb pattern. In addition, the vertical cross-sectional shape of each protrusion 42 in the longitudinal direction, shown in Figure 11, is also symmetrical and is the same as that of the small protrusion 20. However, each protrusion 42 is different from each small protrusion 20 where the vertical cross-sectional shape of each protuberance 42 in the width direction, shown in Figure 10, is an asymmetrical shape in relation to a neutral plane that is normal for the part similar to plate 18. That is, one of the side walls each protrusion 42 in the width direction is formed at the same angle of inclination as that of each small protrusion 20, while the other side wall of each protrusion 42 has a widely inclined surface 44 on its lateral part from the distal end, the surface being widely inclined 44 is inclined towards the inner side, that is, the side of the central geometric axis of the small protuberance 42, at an angle of inclination Y which is wider than the angle of inclination α. The angle of inclination Y is within a range of 15 ° <y <25 ° and is approximately 20 ° in the present embodiment. The other dimensions P, H, L, d, t and the angles a, 13 are the same as those of each small protuberance 20.
[00125] When the vertical cross-sectional shape in the wide direction is made asymmetrical in this way, when the small protrusions 42 are pressed in the normal direction to the part similar to plate 18, each small protrusion 42 is easily flexed and deformed in the direction of one side in the wide direction, i.e., the side opposite the side on which the widely inclined surface 44 is formed. Figure 12 is a perspective view showing the small protrusions 42 according to the present embodiment. Figure 13 is a plan view which is the same as Figure 9. Each part indicated by close oblique lines is the widely tilted surface 44, and each small protuberance 42 is flexed and deformed in the direction of the opposite side to the side on which the surface widely inclined 44 is formed, as indicated by the outlined arrow. The small protuberances 42 are arranged in such positions that the bending directions are alternately inverted, around the central geometric axis of a corresponding polygon, that is, a corresponding regular hexagon, which constitutes the lattice pattern 34. Specifically, among the six small protrusions 42 arranged on the respective sides that make up each regular hexagon, three small protrusions 42 located in each other position in the circumferential direction are flexed and deformed towards the inside of the regular hexagon and the remaining three small protrusions 42 located between the protrusions 42 described above are flexed and deformed towards the outside of the regular hexagon. In the entire region of the lattice pattern 34, the six small protuberances 42 that make up each regular hexagon are flexed and deformed in the same deformation manner.
[00126] In the present embodiment, in the same way, the multiple small protuberances 42 have an elongated shape in a flat view and are arranged so as to constitute the lattice pattern 34 formed in the regular hexagons. However, variations in the moment when the small bumps 42 are pressed with a finger or hand are suppressed and an excellent sensation is obtained. In this way, it is possible to obtain operating and advantageous effects similar to those of the modality described above.
[00127] Each small protuberance 42 according to the present modality is formed so that the vertical cross-sectional shape in a specific position around the geometric axis, that is, in the direction of width perpendicular to the longitudinal direction, is an asymmetric shape and is elastically deformed so as to always fall in a predetermined direction of flexion. However, variations in sensation are suppressed and substantially the same sensation is obtained in a stable manner.
[00128] Each small protuberance 42 has a widely inclined surface 44. Therefore, each small protuberance 42 is easily flexed and deformed in the direction of the side opposite the side on which the widely inclined surface 44 is formed. Accordingly, it is possible to further improve the smooth sensation obtained through the elastic deformation of the small protuberances 42. In addition, by controlling the ease of flexing each small protuberance 42 at the base of the strip and at the angle of inclination Y of the widely inclined surface 44, it is possible to adjust appropriately to the smooth feel.
[00129] Furthermore, it is possible to control the direction of bending at the base of the position in which the widely inclined surface 44 is formed. Therefore, by arranging the small protrusions 42 so that the small protrusions 42 do not make contact with each other at the moment of flexion deformation, the small protrusions 42 are arranged as densely as possible. In this way, it is possible to reliably obtain a predetermined smooth sensation through the elastic deformation of the small protuberances 42 while variations in sensation are suppressed due to the presence and absence of the small protuberances 42.
[00130] The small protrusions 42 are arranged so that a small protrusion 42 is arranged on each side of each of the regular hexagons that make up the truss.
[00131] The pattern 34 and the small protuberances 42 are arranged in such positions that the bending directions are alternately reversed. Therefore, the manner of deformation of the small protrusions 42 in the hexagon unit is substantially the same in the entire region regardless of the fact that each small protrusion 42 is configured so that it is flexed and deformed in a certain direction about its geometric axis. Accordingly, a uniform sensation is obtained.
[00132] In contrast to the ornament 10, an ornament 50 shown in Figure 16 includes the pattern 34 and the small protuberances 42 are arranged in such positions that the bending directions are alternately reversed. Therefore, the manner of deformation of the small protrusions 42 in the hexagon unit is substantially the same in the entire region regardless of the fact that each small protrusion 42 is configured so that it is flexed and deformed in a certain direction about its geometric axis. Accordingly, a uniform sensation is obtained.
[00133] Figure 14 is a view showing a test method to determine the correlation between a reaction force and a stroke with the use of the flattened surface member 16 that has the small protuberances 20 and the flattened surface member 40 that has the small 42 protrusions as test pieces. The surface members 16, 40 each have dimensions of 60 mm by 60 mm and are made of TPO (thermoplastic elastomer olefin) and the multiple small protuberances 20, 42 are arranged to form the lattice patterns in shape of honeycomb 34 as in the modalities described above. Then, the surface members 16, 40 each, were placed on an acrylic-based member in such a position that the small protuberances 20, 42 extend downward and were pressed at a rate of 5 mm / sec with the use of an aluminum indenter whose radius of the spherical distal end is 15 mm. Thus, the correlation between a reaction force and a stroke was measured using a load cell connected to the indenter.
[00134] Figure 15 is a graph showing the characteristic curves of reaction-stroke force obtained through the pressure test, in which the solid line indicates the characteristic curve of the surface member 40 that has the small protuberances 42 in which each one has a wide sloping surface 44 and the long and short alternating dotted line indicates the characteristic curve of surface member 16, which has small protuberances 20, each of which does not have a wide sloping surface 44. As is evident from these characteristic curves, the rate of increase in a reaction force in relation to a stroke is lower in the surface member 40 which has the small protrusions 42 in which each has the widely inclined surface 44 than in the surface member 16 which has the small symmetrical protuberances 20 where each does not have a wide sloping surface 44. Therefore, the surface member 40 provides a better smooth feel.
[00135] In contrast to ornament 10, an ornament 50 shown in Figure 16 includes an upholstery member 52 which is fixedly attached to the surface of surface member 16, that is, the surface of the part similar to plate 18, which is on the side opposite the side on which the small protuberances 20 are formed and has a three-layer structure as a whole that includes the base member similar to the plate 14. Upholstery member 52 is produced from, for example, a fabric , a non-woven fabric, a knitted fabric, vinyl chloride, a flexible film or the like. When the upholstery member 52 is integrally formed with the surface member 16, the upholstery member 52 is formed at the same time as the surface member 16 is formed and is fixedly attached to the surface of the surface member 16. In a state in which the peripheral end parts 54 of the upholstery member 52 are wrapped around the outer periphery edge parts of the base member 14 and are engaged with the engagement protrusions 28 and the ornament 50 is fixedly engaged with the finish of vehicle door 12, the end parts 54 are pressed into the outer periphery edge parts of the base member 14 by the pressure parts 32. In this way, the surface member 16 is fixedly attached to the base member 14 together to the upholstery member 52. Even when the surface member 40 is provided instead of the surface member 16, it is possible to form a three-layer structure by securely attaching the upholstery member 52 to the upper surface of the surface member 40.
[00136] Also with the ornament 50 configured in this way, similar operation and the advantageous effects to those of ornament 10 are obtained. Additionally, the surface member 16 is covered with the padding member 52. Therefore, even if a sunken mark, irregular polish or similar occurs, on the surface of the part similar to the plate 18 of the surface member 16, the surface that is on the side opposite the side on which the small protuberances 20 are formed, the sunken mark, irregular polishing or the like, is not exposed to the outside and damage to the surface member 16 is avoided. Therefore, the range of choices for the resin material of the surface member 16 is expanded and the design flexibility in the shape or the like of each small protuberance 20 in association with the sensation increases. Therefore, it is possible to adjust additionally, easily and appropriately to the sensation.
[00137] In an ornament 60 shown in Figure 17, a cushion member 66 having multiple small protuberances 64 is arranged on the surface of a base member similar to plate 62 and a surface member 68 is provided so as to be laminated on the side of the pad member 66, on which the small protrusions 64 are formed. The base member 62 is produced from a relatively hard synthetic resin material, as in the case of the base member 14 and has the engagement protrusions 28 and the engaging engagement parts 30 that are integrally formed with its rear face. Pad member 66 corresponds to the second member and is produced from an elastically deformable synthetic resin material, as in the case of surface members 16, 40. Pad member 66 has a part similar to the plate 70 which is fitted fixed to the surface of the base member 62 so as to be in close contact with the surface of the base member 62. The multiple small protrusions 64 are formed integrally with the part similar to plate 70. Each of the small protrusions 64 has a configuration similar to each of the small protrusions 20 or 42. The small protrusions 64 are formed so that they protrude from the part similar to the plate 70 towards the surface member 68 and to be in close contact with a rear face 72 at its ends distal so that a space 74 is formed between the rear face 72 of the surface member 68 and the part similar to the plate 70. The rear face 72 corresponds to the conjugated surface. The surface member 68 corresponds to the first member. In the present embodiment, the surface member 68 is produced from a relatively light synthetic resin material, as in the case of the surface members 16, 40. In a state where the outer peripheral end parts 76 of the surface member 68 are wrapped around the outer periphery edge portions of the base member 62 and are engaged with the engagement protrusions 28 (not shown) and the ornament 60 is fixedly attached to the vehicle door finish 12, the end parts 76 are pressed on the outer periphery edge parts of the base member 62 by the pressure parts 32. The padding member 52 can be additionally provided on the surface member 68.
[00138] In the ornament 60 configured in this way, when the surface member 68 is pressed with a finger or a hand, the rear face 72 of the surface member 68 is pressed on the distal ends of the small protuberances 64 of the cushion member 66. Therefore , an excellent sensation is obtained through elastic deformation of the small protuberances 64. In this way, advantageous effects similar to those of ornament 10 are obtained. Pad member 66 having small protrusions 64 is covered with surface member 68 and the plate-like part 70 of pad member 66 is attached to base member 62. Therefore, even when a sunken mark occurs, irregular polishing or similar, on the surface of the part similar to plate 70, the surface that is on the side opposite the side on which the small protuberances 64 are formed, the sunken mark, irregular polishing or the like, is not exposed to the outside. In this way, the range of choices for the resin material of the cushion member 66 is expanded and the design flexibility in the shape or the like of each small protrusion 64 in association with the sensation increases. Therefore, it is possible to adjust additionally, easily and appropriately to the sensation.
[00139] Figure 18 is a view that illustrates yet another embodiment of the invention and is a three-view drawing of each small protuberance 80 that has a different shape from those of the small protuberances 20, 42. Figure 19 is a perspective view of each small protuberance 80. Figure 18 (a) is a plan view when viewed from the normal direction to the part similar to plate 18, as in the case of Figure 6 (b) and Figure 9. Figure 18 (b) is a side view when viewed from the right side of Figure 18 (a). Figure 18 (c) is a front view when viewed from the bottom of Figure 18 (a). Each small protuberance 80 has an elongated shape that is long in the top-down direction in Figure 18 (a) and has a curved shape that is gently curved in a circular arc shape in its longitudinal direction. A right side face 82 is a concave curved surface and a left side face 84 is a convex curved surface. The cross-section in the width direction which is the lateral direction in Figure 18 (a) has an asymmetric shape. A widely inclined surface 86 that has an inward tilt angle wider than that of the opposite side is formed in a part near the distal end. Each small protuberance 80 is easily flexed and deformed towards the right side face 82 as indicated by an established outlined arrow. A part indicated by close oblique lines in Figure 18 and Figure 19 indicates the band of the widely inclined surface 86. The small protuberances 80 configured in this way, as in the case, for example, of the small protuberances 42, are arranged so as to constitute the lattice pattern 34 formed of polygons and are arranged in such positions that the bending directions are alternately reversed, around the central geometric axis of a polygon correspondent. In this way, it is possible to obtain similar operation and the advantageous effects to those of the modality in which the small protuberances 42 are formed. In addition, the stiffness in a pressure load is increased due to the curved shape. Therefore, the control range in a smooth feel and a rigid feel is extended.
[00140] Figure 20 is a view that illustrates yet another embodiment of the invention and is a three-view drawing of each small protrusion 90 that has a different shape from those of the small protuberances 20, 42. Figure 21 is a perspective view of each small protuberance 90. Figure 20 (a) is a plan view when viewed from the normal direction to the part similar to plate 18, as in the case of Figure 6 (b) and Figure 9. Figure 20 (b) is a side view when viewed from the right side of Figure 20 (a). Figure 20 (c) is a front view when viewed from the bottom of Figure 20 (a). Each small lump 90 has an elongated shape that is long in the top-down direction in Figure 20 (a) and has a cocoon shape that is gently curved into a crank shape in its longitudinal direction. The cross-section in the wide direction which is the lateral direction in Figure 20 (a) has a symmetrical shape in a central part in the longitudinal direction, but has an asymmetrical shape in end parts in the longitudinal direction. A pair of widely inclined surfaces 92, 94 each of which has an inward tilt angle wider than that of the opposite side is formed. The widely inclined surfaces 92, 94 are formed on opposite sides in the lateral direction and each small protuberance 90 is flexed and deformed so as to be twisted around the central geometric axis as indicated by the outlined arrows. Parts indicated by the oblique lines next in Figure 20 and Figure 21 are the bands of the widely inclined surface 92, 94. The small protuberances 90 configured in this way, as in the case, for example, of the small protuberances 20, are arranged in order to constitute the lattice pattern 34 formed of polygons. In this way, it is possible to obtain similar operation and advantageous effects to those of the modality in which the small protuberances 20 are formed. In addition, each of the small protuberances 90 according to the present embodiment is elastically deformed in a uniform deformation manner. Therefore, variations in sensation are suppressed and substantially the same sensation is obtained in a stable manner. In addition, it is possible to easily adjust the smooth sensation by controlling the ease of flexing of each small protuberance by changing the range or angle of inclination of each of the widely inclined surfaces 92, 94.
[00141] Figure 22 and Figure 23 are views that illustrate yet another embodiment of the invention, in which three small protuberances 20 are coupled together. Figure 22 is a drawing of three views of each group of small protuberance 100. Figure 23 is a perspective view of each group of small protuberance 100. Coupling the three small protuberances 20 to each other by means of a part of coupling 102 as described above, the three small protrusions 20 support each other. Therefore, the stiffness in a pressure load increases and the control range in a smooth feeling and a stiff feeling is increased. In the present embodiment, the small protuberances 20 are described. Alternatively, the other small protrusions, such as the small protrusions 42, can also be coupled together as described above. The number of small bumps in a group is not necessarily three and can be determined as needed.
[00142] Figure 24 is an enlarged plan view that corresponds to Figure 6 (b). Figure 25 is an enlarged vertical cross-sectional view taken along line XXV-XXV in Figure 24. Multiple small protuberances 202 are formed in a part similar to the plate 201 of a second member 200 which is used as the surface member 16 , 40 or the cushion member 66. Each small protrusion 202 diverges from each small protrusion 20 in the corner shape of the base part from which the small protrusion 202 protrudes from the part similar to plate 201. That is, a part of each small protrusion 202, which protrudes from the part similar to plate 201, is the same as that of each small protrusion 20. However, a groove 204 that has a semicircular cross section is formed along the entire length of each small protrusion 202 in the longitudinal direction, in one of the base parts in the direction of width perpendicular to the longitudinal direction of the small protuberance 202 which has a rectangular rectangular shape in a plan view. Therefore, the flexural stiffness on one side in the wide direction (lateral direction in Figure 25), in which the groove 204 is formed, becomes inferior and each small protuberance 202 is easily flexed and deformed towards the side on which groove 204 is formed. The parts indicated by the oblique lines next in Figure 24 are grooves 204. The arrows outlined in Figure 24 and Figure 25 indicate directions in which the small bumps 202 fall. As shown in Figure 9 (see Figure 13), the small protrusions 202 are arranged in such positions that the bending directions are alternately inverted, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The radius r of the circular arc of each groove 204 is, for example, approximately 0.5 mm.
[00143] Also in the present embodiment, a small protrusion 202 is arranged on each side of one of the regular hexagons that constitute the lattice pattern 34 and the small protuberances 202 are arranged in such positions that the flexion directions are alternately reversed. Therefore, by arranging the small protrusions 202 as densely as possible so that the small protrusions 202 do not come into contact with each other at the time of flexion deformation, a predetermined smooth sensation through elastic deformation of the small protrusions 202 is obtained safely while variations in sensation are suppressed. In addition, the manner of deformation of the small protuberances 202 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, similar operation and the advantageous effects to those of the modality shown in Figure 9 are obtained.
[00144] It is only necessary to form the groove 204 along each of the small protrusions 202. Therefore, a molding matrix used to mold the second member 200 that has the multiple small protrusions 202 and the grooves 204 is easily formed at low cost . Therefore, the manufacturing cost is reduced. In addition, it is possible to control the ease of flexing of each small protrusion 202 based on the width or depth of each groove 204. Therefore, it is possible to adjust the smooth feel easily and appropriately.
[00145] Figure 26 is an enlarged plan view corresponding to Figure 24. Figure 27 is an enlarged vertical cross-sectional view taken along line XXVII-XXVII in Figure 26. A second member 210 diverges from the second member 200 in the corner shape of the base part of each small protuberance 212. That is, in the present embodiment, instead of forming the groove 204, a rounded part 214 that is gently curved from a part similar to plate 211 in a relatively large radius is formed on the side opposite the side on which the groove 204 is formed. Therefore, a flexural stiffness on one side in the wide direction (lateral direction in Figure 27), in which the rounded part 214 is formed, becomes larger and each small protuberance 212 is easily flexed and deformed towards the opposite side to the side on which the rounded part 214 is formed. The parts indicated by the oblique lines next in Figure 26 are the rounded parts 214. The arrows outlined in Figure 26 and Figure 27 indicate directions in which the small bumps 212 fall. As shown in Figure 24, the small protrusions 212 are arranged in such positions that the bending directions are alternately inverted, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The radius r of each rounded part 214 is, for example, approximately 0.5 mm.
[00146] Also in the present modality, with the small bumps 212 being arranged as densely as possible, a predetermined smooth sensation through elastic deformation of the small bumps 212 is obtained safely while the variations in sensation are suppressed. In addition, the manner of deformation of the small protrusions 212 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, similar operation and the advantageous effects to those of the modality shown in Figure 24 are obtained. It is only necessary to form the rounded part 214 along each of the small protrusions 212. Therefore, a molding matrix used to mold the second member 210 which has the multiple small protrusions 212 and the rounded part 214 is easily formed at low cost. Therefore, the manufacturing cost is reduced. In addition, it is possible to control the ease of bending each small protrusion 212 based on the dimension of the radius r of each rounded part 214. Therefore, it is possible to adjust the smooth feel easily and appropriately.
[00147] Figure 28 is an enlarged plan view corresponding to Figure 24. Figure 29 is an enlarged vertical cross-sectional view taken along line XXIX-XXIX in Figure 28. A second member 220 diverges from the second member 200 in configuration of each small protrusion 222. That is, in the present modality, instead of forming the groove 204, each small protrusion 222 that has the same shape as each small protrusion 20 is divided into two parts in relation to a divided plane that is parallel to the longitudinal direction and the two parts are respectively formed of a high hardness part 225 and a low hardness part 227. Therefore, the flexural stiffness on one side in the wide direction (lateral direction in Figure 29), in which the the high hardness part 225 is arranged becomes larger and each small protuberance 222 is easily flexed and deformed towards the opposite side on which the low hardness part 227 is arranged. Each high hardness part 225 is produced from a high hardness material 224 which also forms the main part of the board-like part 221, while each low hardness part 227 is produced from a low hardness material 226 which also it is laminated on the surface side of the high hardness material 224 and is integrally formed with the laminated part on the surface side of the high hardness material 224 through, for example, insertion molding. The parts indicated by the close oblique lines in Figure 28 are the high hardness parts 225. Arrows outlined in Figure 28 and Figure 29 indicate directions in which the small protrusions 222 fall. As shown in Figure 24, the small protrusions 222 are arranged in such positions that the bending directions are alternately reversed, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34.
[00148] The hardness of each high hardness material 224 and the hardness of each low hardness material 226 are suitably arrows as relative values so that a predetermined flexural stiffness is obtained. For example, in the type A durometer hardness that is measured according to JIS K6253, preferably, the high hardness material 224 has a hardness of approximately 80 and the low hardness material 226 has a hardness of approximately 40. The materials of synthetic resins that are melt bonded to each other through insertion molding are appropriately selected.
[00149] Also in the present modality, arranging the small protrusions 222 as densely as possible so that the small protrusions 222 do not come into contact with each other in the time of flexion deformation, a soft sensation predetermined through elastic deformation of the small lumps 222 is obtained safely while variations in sensation are suppressed. In addition, the manner of deformation of the small protrusions 222 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, similar operation and the advantageous effects to those of the modality shown in Figure 24 are obtained. In addition, it is possible to control the bending ease of each small protrusion 222 by changing the materials and the positions of the planes divided into the high hardness material 224 and the low hardness material 226. Therefore, it is possible to adjust the smooth feel easily and appropriately.
[00150] A second member 230 shown in Figure 30 diverges from the surface member 40 shown in Figure 9 in the position in which each small protrusion 232 is arranged in a part similar to plate 231. Each small protrusion 232 has the same shape as each small protrusion 42. However, each small protrusion 232 is inclined by a predetermined angle (which is within a range of, for example, approximately 10 ° to approximately 30 ° and approximately 20 ° in the present embodiment) with respect to a corresponding side of each of the hexagons that make up the lattice pattern 34. In the case that each small protrusion 42 is arranged parallel to a correspondent on the sides of each hexagon as shown in Figure 9, when each small protrusion 42 is flexed and deformed by a load of compression, the small protuberance 42 falls towards the center of a corresponding hexagon as indicated by the close oblique lines in Figure 31 (the ). Therefore, the height of each small protrusion 42 is restricted in order to avoid contact between the small protrusions 42. In contrast, when each small protrusion 232 is tilted as shown in Figure 30, the directions in which the small protrusions 232 fall displaced from each other as indicated by the oblique lines next in Figure 31 (b). Therefore, small protrusions 232 are less likely to come into contact with each other, and, consequently, it is possible to increase the height of each small protrusion 232, thus improving the smooth feel. Small protrusions according to the other modalities, such as small protrusions 202, 212, 222, can also be arranged so as to be inclined in the manner described above.
[00151] Figure 32 is a graph that shows the results obtained by determining the characteristic curves of reaction force-stroke according to the test method shown in Figure 14, in relation to the case where the height H of each small protrusion 42 shown in Figure 9 is 2.5 mm and the case where the height H of each small protrusion 42 shown in Figure 9 is 3.5 mm As is evident from Figure 32, the reaction force in the case where height H is 3.5 mm less than in the case where height H is 2.5 mm. Therefore, an excellent smooth sensation is obtained in the case where the height H is 3.5 mm. The dimensions P, L, d, t and the angles α, β of several parts, in addition to the height H, are the same.
[00152] Figure 33 is an example in which the smooth sensation is enhanced by changing an aspect ratio. Figure 33 (a) is a plan view of each small protrusion 20 according to the embodiment shown in Figure 6. Each small protuberance 240 shown in Figure 33 (b) is formed so that the width is changed to half the width of each small hump 20, that is, d / 2, while the length L is the same as that of each hump 20. In this case, due to the fact that the width is half the width of each small hump 20, each small hump 240 is more easily flexed and deformed in the wide direction. Therefore, the smooth feeling improves. In relation to the other small protuberances, such as the small protuberance 42, the soft sensation can be adjusted by changing the aspect ratio.
[00153] A second member 250 shown in Figure 34 has small protrusions 254 in which each has a trapezoidal shape in a plan view when viewed from the normal direction to a part similar to plate 252. Figure 34 (a) is a enlarged plan view corresponding to Figure 24. Figure 34 (b) is an enlarged plan view of one of the small protrusions 254. Figure 35 is a vertical cross-sectional view taken along line XXXV-XXXV in Figure 34 (b ). Figure 36 is a perspective view of a plurality of small protrusions 254. In each small protrusion 254, a widely inclined surface 256 is formed on the side on which the long side (bottom base) of the trapezoidal shape is present and the flexural stiffness towards the opposite side, that is, the side on which the short side (upper base) is present, which is the left side in Figure 34 (b) and Figure 35, is made lower and each small protrusion 254 is easily flexed and deformed towards the side on which the short side is present. Parts indicated by the close oblique lines in Figure 34 (b) and Figure 36 are the widely inclined surfaces 256. Arrows outlined in Figure 34 to Figure 36 indicate directions in which the small protrusions 254 fall. As shown in Figure 24, the small protrusions 254 are arranged in such positions that the bending directions are alternately inverted, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The dimensions a, b, c of the trapezoidal shape are approximately 1.8 mm, approximately 0.9 mm and approximately 1.8 mm, respectively, and the corner radius of each corner part is approximately 0.3 mm. Additionally, height H 2 , 5 mm, thickness t 1.5 mm, the angle of inclination one of each of the side walls on the respective sides in the vertical cross-section in Figure 35 10 ° and the angle of inclination 7 of each widely inclined surface 256 45 °.
[00154] Also in the present embodiment, a small protrusion 254 is arranged on each side of one of the regular hexagons that constitute the lattice pattern 34 and the small protrusions 254 are arranged in such positions that the bending directions are alternately reversed. Therefore, by arranging the small protrusions 254 as densely as possible so that the small protrusions 254 do not come into contact with each other at the time of flexion deformation, a predetermined smooth sensation through elastic deformation of the small protrusions 254 is obtained from safely while variations in sensation are suppressed. In addition, the manner of deformation of the small protrusions 254 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, similar operation and the advantageous effects to those of the modality shown in Figure 9 are obtained.
[00155] On the other hand, when the shape of each small protrusion 254 in a flat view is a trapezoidal shape as described above, the flexural stiffness becomes less than when the shape of each small protrusion in a flat view is a square format. Therefore, a greater smooth sensation is obtained. In that case, dimension b on the short side is preferably set to less than or equal to two thirds of dimension one on the long side. Due to the fact that the wide sloping surface 256 is formed on the side on which the long side of the trapezoidal shape is present, it is possible to obtain a smooth feeling that is greater than when a wide sloping surface is formed on the side on which the side short is present.
[00156] In addition to a product (second member 250) according to the modality described above, a product according to a first modified example shown in Figure 37 to Figure 40, a product according to a second modified example shown in Figure 41 to Figure 43 and a product according to a third modified example shown in Figure 44 to Figure 46 were prepared and then the characteristic curves of reaction-stroke force were determined according to the test method shown in Figure 14. The results shown in Figure 47 were obtained.
[00157] A second member 260 according to the first modified example shown in Figure 37 to Figure 40 has small protrusions 264 in which each has a substantially square shape in a plan view when viewed from the normal direction to a similar part to plate 262. Figure 37 (a) is an enlarged plan view corresponding to Figure 24. Figure 37 (b) is an enlarged plan view of one of the small protrusions 264. Figure 38 is a vertical cross-sectional view taken along line XXXVIII-XXXVIII in Figure 37 (b). Figure 39 is a vertical cross-sectional view taken along line XXXIX-XXXIX in Figure 37 (b). Figure 40 is a perspective view of a plurality of small protrusions 264. Each of the dimensions a, b of each small protrusion 264 is approximately 1.8 mm and the corner radius of each corner part is approximately 0, 3 mm. Additionally, height H 2.5 mm, thickness t 1.5 mm, the angle of inclination one of each of the side walls on the respective sides in the vertical cross-section in Figure 38 10 ° and the angle of inclination β of each of side walls on the respective sides in the vertical cross-section in Figure 39 5 °. According to the first modified example, each small protrusion 264 is difficult to flex and deform in a diagonal direction of the square shape and is relatively and easily flexed and deformed in the lateral direction in Figure 37 (b) and Figure 38 due to the difference between the tilt angle a and tilt angle β. The first modified example corresponds to a modality of the invention in which the flexural stiffness is anisotropic around the geometric axis of each small protuberance.
[00158] A second member 270 according to the second modified example shown in Figure 41 to Figure 43 has small protrusions 274 in which each has a substantially square shape in a plan view when viewed from the normal direction to a part similar to the plate 272. Figure 41 (a) is an enlarged plan view corresponding to Figure 24. Figure 41 (b) is an enlarged plan view of one of the small protrusions 274. Figure 42 is a vertical cross-sectional view taken at along the XLIIXLII line in Figure 41 (b). Figure 43 is a vertical cross-sectional view taken along line XLIII-XLIII in Figure 41 (b). Each small protrusion 274 is substantially the same as that of the first modified example, but diverges from each small protrusion in the first modified example in the fact that each small protrusion 274 has a wide sloping surface 276 which has an angle of inclination 7, the rigidity in bending towards the side opposite the side on which the widely inclined surface 276 is formed, that is, towards the left side in Figure 41 (b) and Figure 42, is made inferior and each small protuberance 274 is easily flexed and deformed in towards the left side. A part indicated by the oblique lines next in Figure 41 (b) is the widely tilted surface 276. Arrows outlined in Figure 41 to Figure 42 indicate the directions in which the small protrusions 274 fall. As shown in Figure 24, the small protrusions 274 are arranged in such positions that the bending directions are alternately inverted, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The angle of inclination 7 is approximately 45 ° and the dimensions a, b, R, H, t and the angles α, β of several parts besides the angle of inclination 7 are the same as those of each small protrusion 264 according to the first modified example. The second modified example also corresponds to a modality of the invention in which flexion stiffness is anisotropic around the geometric axis of each small protuberance.
[00159] A second member 280 according to the third modified example shown in Figure 44 to Figure 46 has small protrusions 284 in which each has a trapezoidal shape in a flat view when viewed from the normal direction to a part similar to the plate 282. Figure 44 (a) is an enlarged plan view corresponding to Figure 24. Figure 44 (b) is an enlarged plan view of one of the small protrusions 284. Figure 45 is a vertical cross-sectional view taken along line XLV-XLV in Figure 44 (b). Figure 46 is a vertical cross-sectional view taken along line XLVI-XLVI in Figure 44 (b). Each small protrusion 284 is substantially the same as each small protrusion 254 of the second member 250 which is the product according to the modality, but diverges from each small protrusion 254 in the fact that on the broadly inclined surface 256 which has an angle of inclination 7 it is formed and each of the vertical cross-section sections shown in Figure 45 and Figure 46 has a symmetrical shape in relation to the center line. In this case too, each small protrusion 284 is easily flexed and deformed towards the left side in Figure 44 (b) and Figure 45, that is, towards the side on which the short side of the trapezoidal shape is present. As in the case of the second member 250 shown in Figure 34, the small protrusions 284 are arranged in such positions that the bending directions are alternately reversed, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The dimensions a, b, c, R, H, t and the angle a of several parts are the same as those of each small protrusion 254 of the second member 250 and the angle of inclination β of each of the side walls on the respective sides in the section in cross section in Figure 46 is approximately 5 °. β 5 ° also applies to each small protrusion 254. The third modified example also corresponds to a modality of the invention in which flexion stiffness is anisotropic around the geometric axis of each small protrusion.
[00160] As is evident from the test results in Figure 47, in the product according to the modality shown in Figure 34, that is, the second member 250 that has small protrusions 254 in which each has a trapezoidal shape and the widely inclined surface 256, the reaction force (flexural stiffness) is less than that of the second modified example in which the small protrusions 274 in which each have a square shape and the widely inclined surface 276 are formed. Therefore, an excellent smooth sensation is obtained. In addition, in the third modified example in which the small protrusion 284 in which each has a trapezoidal shape and no widely inclined surfaces are formed, the soft sensation is inferior to that of the product according to the modality. However, a smooth feel that is better than that of the second modified example is obtained. From these points of view, it is considered that only by forming each protrusion in a trapezoidal shape in a flat view, each small protrusion is more easily flexed and deformed. As a result, the reaction force becomes less and an excellent smooth feeling is obtained. The difference in reaction force between the product according to the modality and the product according to the modified third example and the difference in the reaction force between the product according to the second modified example and the product according to the first example modified depends on the presence or absence of the widely inclined surfaces 256, 276. Therefore, it is found that, by forming the widely inclined surfaces 256, 276, the reaction force becomes inferior and the smooth sensation is improved.
[00161] A second member 300 shown in Figure 48 has small protrusions 304 in which each has a semicircular shape in a plan view when viewed from the normal direction to a part similar to plate 302. Figure 48 (a) is a enlarged plan view corresponding to Figure 24. Figure 48 (b) is an enlarged plan view of one of the small protrusions 304. Figure 49 is a vertical cross-sectional view taken along the XLIXXLIX line in Figure 48 (b). Figure 50 is a perspective view of a plurality of small protrusions 304. Each small protrusion 304 has a wide sloping surface 306 on the side on which the linear part of the semicircular shape is present, the stiffness in flexing towards the opposite side, or that is, towards the side on which the circular arc is present, which is the left side in Figure 48 (b) and Figure 49, it is made inferior and each small protuberance 304 is easily flexed and deformed towards the side on which the arc circular is present. Parts indicated by the close oblique lines in Figure 48 (b) and Figure 50 are the widely inclined surfaces 306. Arrows outlined in Figure 48 to Figure 50 indicate directions in which the small protuberances 304 fall. As shown in Figure 24, the small protuberances 304 are arranged in such positions that the bending directions are alternately reversed, around the central geometric axis of a correspondent of the regular hexagons that make up the lattice pattern 34. Each of the dimensions longitudinal and lateral a, b of the semicircular shape is approximately 1.8 mm and the radius R of the semicircular arch is approximately 0.9 mm. In addition, the height H 2.5 mm, the thickness t 15 mm, the angle of inclination α1 of the side wall on the side of the widely inclined surface 306, that is, the side of the linear part, in the vertical cross-section in Figure 49 10 °, the angle of inclination a2 on the opposite side, that is, the arc side circular 5 ° and the tilt angle 7 of the widely inclined surface 306 45 °.
[00162] Also in the present embodiment, a small protrusion 304 is arranged on each side of one of the regular hexagons that make up the lattice pattern 34 and the small protrusions 304 are arranged in such positions that the bending directions are alternately reversed. Therefore, by arranging the small protrusions 304 as densely as possible so that the small protrusions 304 do not come into contact with each other at the time of flexion deformation, a predetermined smooth sensation through elastic deformation of the small protrusions 304 is obtained from safely while variations in sensation are suppressed. In addition, the manner of deformation of the small protuberances 304 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, the similar operation and the advantageous effects to those of the modality shown in Figure 9 are obtained.
[00163] On the other hand, when the shape of each small protrusion 304 in a plan view is a semicircular shape as described above, flexural stiffness becomes less than when the shape of each small protrusion in a plan view is a shape square as in the second modified example. Therefore, a greater smooth sensation is obtained. Due to the fact that the widely inclined surface 306 is formed on the side on which the linear part of the semicircular shape is present, it is possible to obtain a smooth sensation that is greater than when a widely inclined surface is formed on the circular arc side.
[00164] In addition to a product (second member 300) according to the modality described above, the product according to the first modified example shown in Figure 37 to Figure 40, the product according to the second modified example shown in Figure 41 to Figure 43 and a product according to a fourth modified example shown in Figure 51 to Figure 53 were prepared and then the characteristic curves of reaction-stroke force were determined according to the test method shown in Figure 14. The results shown in Figure 54 were obtained.
[00165] A second member 310 according to the fourth modified example shown in Figure 51 to Figure 53 has small protrusions 314 in which each has a semicircular shape in a plan view when viewed from the normal direction to a part similar to the plate 312. Figure 51 (a) is an enlarged plan view corresponding to Figure 24. Figure 51 (b) is an enlarged plan view of one of the small protrusions 314. Figure 52 is a vertical cross-sectional view taken along line LII-LII in Figure 51 (b). Figure 53 is a perspective view of a plurality of small protrusions 314. Each small protrusion 314 is substantially the same as each small protrusion 304 of the second member 300 which is the product according to the modality, but diverges from each small protrusion 304 in the fact that no wide sloping surface 306 having an angle of inclination 7 is formed, the side wall on the right side, that is, the side on which the linear part of the semicircular shape is present, in the vertical cross section shown in Figure 52 extends to its distal end part at an angle of inclination α1 and a flattened surface 316 parallel to the part similar to plate 312 is formed at the distal end. In this case too, each small protuberance 314 is easily flexed and deformed towards the left side in Figure 51 (b) and in Figure 52, that is, towards the side on which the circular arc of the semicircular shape is present. As in the case of the second member 300 shown in Figure 48, the small protrusions 314 are arranged in such positions that the bending directions are alternately reversed, around the central geometric axis of a correspondent of the regular hexagons that constitute the lattice pattern 34. The dimensions a, b, R, H, t and the angle of inclination α1, α2 of several parts are the same as those of each small protuberance 304 of the second member 300. The fourth modified example also corresponds to a modality of the invention in which the stiffness flexion is anisotropic around the geometric axis of each small protuberance.
[00166] As is evident from the test results in Figure 54, in the product according to the modality shown in Figure 48, that is, the second member 300 that has small protrusions 304 in which each has a semicircular shape and the widely inclined surface 306, the reaction force (flexural stiffness) is less than that of the second modified example in which the small protrusions 274 each have a square shape and the widely inclined surface 276 are formed. Therefore, an excellent smooth sensation is obtained. From these points of view, it is considered that, only by forming each protuberance in a semicircular shape in a flat view, each small protuberance is easily flexed and deformed. As a result, the reaction force becomes less and an excellent smooth feeling is obtained. The difference in reaction force between the product according to the modality and the product according to the modified fourth example and the difference in the reaction force between the product according to the second modified example and the product according to the first example modified depends on the presence or absence of the widely inclined surfaces 276, 306. Therefore, it appears that, forming the widely inclined surface 276, 306, the reaction force becomes inferior and the smooth sensation is improved. The reaction force in the fourth modified example is greater than that of the first modified example for the following reason. The distal end of each small protrusion 264 has a semi-cylindrical shape (D shape) in the first modified example As is evident from Figure 40 and each small protrusion 264 is brought into line contact with the base member in the initial contact stage with the base member, while the distal end of each small protrusion 314 has the flattened surface 316 in the modified fourth example and each small protrusion 314 is brought into flat contact with the base member of the initial stage of contact with the base member and therefore, each small lump 314 becomes difficult to tip over and the reaction force is increased.
[00167] A second member 320 shown in Figure 55 has small protrusions 324 in which each has a trapezoidal shape in a plan view, in which one side of a square shape is tilted when viewed from the normal direction to a part similar to plate 322. Figure 55 (a) is an enlarged plan view corresponding to Figure 24. Figure 55 (b) is an enlarged plan view of one of the small protuberances 324. Figure 56 is a vertical cross-sectional view taken along the LVI-LVI line in Figure 55 (b). Figure 57 is a perspective view of a plurality of small protrusions 324. In each small protrusion 324, a widely tilted surface 326 is formed on a side face on the side opposite the side on which the inclined side of the trapezoidal shape is present and the flexural stiffness towards the side on which the inclined side is present, that is, the left side in Figure 55 (b) and Figure 56, is made inferior and each small protuberance 324 is easily flexed and deformed towards the side in which the inclined side is present. The parts indicated by the close oblique lines in Figure 55 (b) and Figure 57 are the widely inclined surfaces 326. Arrows outlined in Figure 55 to Figure 57 indicate directions in which the small protuberances 324 fall. As shown in Figure 24, the small protuberances 324 are arranged in such positions that the flexing directions are alternately inverted, around the central geometric axis of a correspondent of the regular hexagons that make up the lattice pattern 34. Here, each small protuberance 324 is arranged in such a position that the sloping side of the trapezoidal shape is parallel to a corresponding side of each regular hexagon. The dimensions a, b, c of various parts of the trapezoidal shape are approximately 1.8 mm, approximately 1.35 mm and approximately 1.8 mm, respectively. Additionally, the height H 2.5 mm, the thickness t 1.5 mm, the angle of inclination one of each of the side walls on the respective sides in the vertical cross-section in Figure 56 10 ° and the angle of inclination 7 of the wide sloping surface 326 45 °.
[00168] Also in the present embodiment, a small protrusion 324 is arranged on each side of one of the regular hexagons that constitute the lattice pattern 34 and the small protuberances 324 are arranged in such positions that the flexion directions are alternately reversed. Therefore, by arranging the small protrusions 324 as densely as possible so that the small protrusions 324 do not come into contact with each other at the time of flexion deformation, a predetermined smooth sensation through elastic deformation of the small protrusions 324 is obtained from safely while variations in sensation are suppressed. In addition, the manner of deformation of the small protuberances 324 in the hexagon unit is substantially the same over the entire range and a uniform sensation is obtained. In this way, similar operation and the advantageous effects to those of the modality shown in Figure 9 are obtained.
[00169] On the other hand, when each small protuberance 324 is formed in a trapezoidal shape in a flat view as described above, the flexural stiffness is less than when the shape of each small protuberance in a flat view is a square shape like in the second modified example and therefore a greater smooth sensation is obtained. In addition, each small protuberance 324 is easily flexed and deformed in the direction perpendicular to the sloping side of the trapezoidal shape. Therefore, by adjusting the angle of inclination of the inclined side, it is possible to easily control the tipping direction while obtaining an improved smooth feel.
[00170] Figure 58 shows the case in which the arrangement pattern of the small protrusions 42 is different from that of Figure 9 and shows the case in which the multiple small protrusions 42 are arranged so as to constitute a lattice pattern 110 formed of squares . A small protrusion 42 is arranged on each side of a correspondent of squares that make up the lattice pattern 110, in such a position that the longitudinal direction of the small protrusion 42 is parallel to a correspondent on the sides and the small protuberances 42 are arranged in such positions that the bending directions are alternately reversed, around the center line of the corresponding one of the squares. In this way, the way of deformation of the small protrusions 42 in the square unit is substantially the same in the entire region regardless of the fact that each small protrusion 42 is configured to be flexed and deformed in a certain direction around its geometric axis . Therefore, a uniform sensation is obtained. That is, advantageous effects similar to the modality shown in Figure 9 are obtained. The other small protuberances, such as the small protuberances 20, can also be arranged to form the lattice pattern 110 formed of squares as described above. In the present embodiment, the lattice pattern 110 formed of squares is described. Alternatively, the small protrusions 42 can be arranged to form a lattice pattern formed by diamonds, a lattice pattern formed by rectangles or a lattice pattern formed by parallelograms.
[00171] Figure 59 shows the case in which the arrangement of the small protrusions 20 is different from that in Figure 6 and shows the case in which the multiple small protrusions 20 are arranged so as to constitute a lattice pattern 112 formed of equilateral triangles. A small protrusion 20 is arranged on each side of a correspondent of the equilateral triangles that make up the lattice pattern 112 in such a position that the longitudinal direction of the small protrusion 20 is parallel to a correspondent on the sides. Also in that case, the multiple small protuberances 20 that are formed to form the lattice pattern 112 are arranged so that the longitudinal directions are displaced from each other by a predetermined angle. Therefore, an appropriate rigid sensation is obtained due to the fact that the small protuberances 20 support each other. Consequently, it is possible to establish an excellent additional sensation by a combination of the appropriate rigid sensation and the soft sensation that is obtained through elastic deformation of the small protuberances 20. Therefore, the similar operation and the advantageous effects to those of the modality shown in Figure 6 are obtained . The other small protrusions, such as the small protrusions 42, can also be arranged so as to form the lattice pattern 112 formed of equilateral triangles in this way.
[00172] The lattice pattern 112 shown in Figure 59 can be replaced by a lattice pattern in which regular hexagons 114 are consecutively repeated. In this case, the small protrusions 20 are arranged in such positions that the longitudinal direction of each small protrusion 20 is perpendicular to a corresponding side of each regular hexagon 114. The lattice pattern 34 shown in Figure 6 (b) can also be replaced by a lattice pattern in which the equilateral triangles are repeated consecutively. By changing the spacing of each front truss from the truss pattern 110 shown in Figure 58 by a half spacing, the truss pattern 110 shown in Figure 58 can be replaced by a front truss pattern in which the small protrusions 42 are arranged in the respective front sides in such positions that the longitudinal direction of each small protuberance 42 is perpendicular to a corresponding side.
[00173] A lattice pattern 120 shown in Figure 60 is formed from a combination of three types of polygons, that is, a quadrangle (square in the drawing) 122, a hexagon (regular hexagon in the drawing) 124 and an octagon 126. Such a modality is also a modality of the invention. In the lattice pattern 120, three types of polygons are repeated in the same pattern. Alternatively, the small protuberances 20 can be formed to form a lattice pattern in which multiple types of polygons are irregularly combined with one another. Instead of the small bumps 20, the other small bumps, such as the small bumps 42, can also be used.
[00174] Figure 61 is a cross-sectional view corresponding to a cross-section taken along the line LXI-LXI in Figure 1. A pair of an input port 130 and an output port 132 is provided on the member base 14 of the ornament 10. A heating medium (air) whose temperature has been adjusted by an air conditioner 134 of the vehicle is supplied from a pipe 136 to the space 24 of the ornament 10 by means of the entrance door 130 and is discharged from the entrance door. exit 132 to be circulated inside the vehicle by means of a tube 138 as indicated by arrows (->). The pipe 136 is allowed to be connected to a vehicle body side pipe 142 or separate from the one provided on an instrument panel 140 and to be tightly connected to the pipe 142 by means of a sealing member as shown in the drawing while the door is closed. In the present embodiment, preferably, the end parts 26 of the surface member 16 are hermetically fixed to the outer periphery edge parts of the base member 14 by an adhesive agent or the like.
[00175] In the present embodiment, the heating medium (air) whose temperature has been adjusted by the air conditioner 134 is supplied to the space 24 of the ornament 10. Therefore, it is possible to further improve the sensation of the surface member 16. The other ornaments, such as like the ornament that includes the member surface 40, can also be configured as described above.
[00176] In Figure 61, the heating medium is supplied to space 24. Alternatively, compressed gas, like compressed air, can be filled to space 24 in advance and hermetically sealed. The surface member 16 is propelled so that it protrudes based on the pressure of the compressed gas. Therefore, it is possible to give an appropriate rigid sensation to the parts in addition to the small protuberances 20, thus further improving the sensation. The other ornaments can also be configured as described above. In each of the modalities described above, the pressure in spaces 24, 74 is atmospheric pressure and spaces 24, 74 do not need to be hermetically sealed.
[00177] The modalities of the invention are described in detail with reference to the drawings. However, the modalities described above are only examples of the modalities. The invention can be implemented in several other modalities obtained by making modifications or improvements to the modalities described above based on the knowledge of people skilled in the art.
