SUMMARY OF THE INVENTION
TECHNICAL PROBLEM Recently, the feed pen similar to the aforementioned stick-like material feed container often receives many components internally, and therefore a radial enlargement is feared. The power pen thus enlarged is difficult to hold, possibly deteriorating the ease of use. In addition, since the power supply pen seems large, this also causes a problem in terms of ease of design. Therefore, even in the case of many components inside the power supply pen, it has been requested to obtain the small diameter power supply pen.
An object of the present description is to provide a power supply pen which makes it possible to obtain the small diameter power supply pen.
SOLUTION TO THE PROBLEM
To solve the problems described above, a power pen according to the present disclosure comprises a tubular main body, a head tube, a tubular member, a movable body and a tubular support member. The head tube is engaged with the main body for relative rotation. The tubular member is disposed within the head tube and is configured to load a drawing material. The movable body extends in an axial direction at a rear portion of the drawing material within the tubular member and fully forms a male thread on its outer periphery in the axial direction. The tubular support member is disposed rearwardly with respect to the tubular member and supports the movable body. The tubular member includes a female thread on an inner surface thereof and the female thread is configured for screwing with the male thread. The support member has a projection on an inner surface thereof, and the projection is abutted with the male thread from the outside. The head tube and the main body are relatively rotated in a first direction, so that the tubular member and the support member are relatively rotated and the movable body moves toward the before by the action of screwing caused by the male thread and the female thread, so that the drawing material is extracted from the tubular element.
The feeder pen charges the drawing material into the tubular member, and receives the movable body within the tubular member and the support member. The movable body fully forms the male thread in the axial direction. This ensures screwing and support of the male thread in any given position by the tubular member and the support member. The male thread of this movable body is screwed with the female thread on the inner surface of the tubular element, and is brought into abutment with the projection, which is arranged at the rear of the tubular element, on the inner surface of the tubular element. the support element from the outside. Accordingly, the tubular member screwed with the movable body and the support member supporting the movable body can be arranged in the axial direction, thereby limiting a radial enlargement of the supply pen. Therefore, this power pen provides the small diameter power pen.
The projection described above may be formed in a spiral pattern on the inner surface of the support member. This allows the projection to be engaged with the male thread along the shape of the male thread, thus ensuring an increase in the support force of the male thread through the support member.
The projections described above may be arranged in a plurality of positions along the axial direction on the inner surface of the support member. In this case, the several projections disposed along the axial direction each compress the male thread from the outside. This ensures that the male thread is less likely to exit the support member. Thus, the plurality of projections disposed along the axial direction can increase the resistance against the output of the male thread. The support member may have a slot extending from an end portion to a front side thereof in the axial direction. In this case, the provision of these slots ensures the increase of the radial elastic force at the end portion on the front side of the support member. This ensures the increase of the radial support force by the support member, thus further ensuring reliable prevention of the exit of the movable body from the support member. The support member may comprise an elastic portion. The resilient portion is configured to provide an elastic force external to the movable body supported internally by the support member. In this case, the external elastic force exerted by the elastic portion ensures the further increase of the support force exerted by the support member.
The power supply pen can be configured as follows. Several of the drawing materials, tubular elements, moving bodies and support members are arranged. A plurality of sliding portions coupled to the plurality of respective support members are disposed. The plurality of sliding parts can slide relative to the main body by a predetermined amount. Forward movement of any given sliding portion among the plurality of sliding portions relative to the main body of the predetermined amount exposes any given drawing material from the head tube. Relative rotation of the head tube and the main body in the first direction with a state moves the drawing material forward. This allows the feeding pen to internally receive the several drawing materials. Even if multiple drawing materials are received, this ensures the possibility of keeping the small diameter feeding pen.
ADVANTAGEOUS EFFECTS OF THE INVENTION
According to the present disclosure, the small diameter feeding pen can be easily obtained.

FIG. 3 is a vertical cross-sectional view illustrating the power supply pen of FIG. 1. As shown in FIGS. 1 to 3, a power supply pen 100 according to the present embodiment is a multiple pen that pulls out (extract) suitable for any one of a plurality of drawing materials M1-M4 filling the interior of four respective tubular elements IA-1D by the operation of a user. In this embodiment, the drawing materials M1 to M4 are drawing materials having different colors from each other.
As the drawing materials M1 to M4, for example, the following materials may be used: various cosmetic materials similar to a stick such as lipstick, lip gloss, eyeliner, lip liner, eyebrow, blush, an anticernel, a cosmetic stick, a hair color, and a nail art; or a similar core a stick of stationery material and the like. In addition, elements similar to a very soft stick (such as having a semi-solid shape, a soft solid shape, a soft shape, a jelly form, a foam shape and a paste shape having these materials contained) can be used. A stick-like member having an outside diameter of 1 mm or less, a stick-like member having an outside diameter of 1.5 to 3 mm, or a thick stick-like member outer diameter is 4 mm or more can also be used.
The feeding pen 100 comprises a head tube 2 and a main body 3 as an external configuration. The head tube 2 internally comprises the tubular elements IA to 1D which load the drawing materials M1 to M4. The main body 3 is connected to a rear end portion of the head tube 2, and engages with the head tube 2 so as to be relatively rotatable. In the following description, an "axial line" means a center line of the supply pen 100 which extends from the front to the back of the power pen 100, and an "axial direction" means a direction along the line axial in the direction from front to back. It is assumed that the direction in which the drawing materials M1-M4 are fed outward is a forward direction (a forward direction of travel), and a direction opposite to the direction toward the direction of travel. front (a withdrawal direction) is a backward direction.
Fig. 4 is a vertical cross-sectional view illustrating a configuration of the tubular member IA and a peripheral area thereof. As shown in Fig. 4, a rod-like movable body 5A having a male thread 5a is screwed into an interior of the tubular member IA. The movable body 5A is supported by a tubular support member 6A. The tubular member IA, the movable body 5A and the support member 6A may constitute a replaceable cartridge 10A of the main body 3. Alternatively, a combination of the tubular member IA and the movable body 5A may constitute a replaceable cartridge. The tubular elements IB and IC have a configuration similar to the tubular element IA. It is also possible to form cartridges 10B and 10C using tubular elements IB and IC, moving bodies 5B and 5C, and support members 6B and 6C, respectively. This also applies to the tubular element 1D.
The cartridge 10A comprises a sliding portion 8A and a spring 9A (see Figure 5) at the rear portion. The sliding portion 8A is engaged with the support member 6A in the axial direction. The spring 9A pushes the sliding portion 8A backwards. The cartridge 10A can be removably attached to the sliding portion 8A in the axial direction. Similarly, the cartridges 10B and 10C comprise sliding portions 8B and 8C and springs 9B and 9C at the rear portions, respectively. The first remaining cartridge constituting the tubular member 1D similarly comprises a sliding portion and a spring.
Fig. 5 and Fig. 6 are each a cross-sectional perspective view and a vertical cross-sectional view of the feeding pen 100. Fig. 7 is a cross-sectional perspective view illustrating a forward movement of the first portion. sliding 8A. As shown in FIGS. 5 to 7, the head tube 2 and the main body 3 internally comprise the four tubular elements IA to 1D which load the drawing materials M1 to M4, the four moving bodies, such as the moving body 5A, the four support members, such as the support member 6A, the four springs, such as the spring 9A, and the four sliding portions, such as the sliding portion 8A. These four tubular elements, four movable bodies, four support elements, four springs and four sliding parts have an identical configuration, except that different drawing materials M1-M4 are loaded.
Accordingly, the following refers to each of the four tubular members, the four movable bodies, the four support members, the four springs and the four sliding portions in the form of a tubular member 1, a movable body 5, a a support member 6, a spring 9, and a sliding portion 8. The four cartridges, such as the cartridge 10A, and the drawing materials M1-M4 are indicated as cartridge 10 and drawing material M , respectively.
A median tube 11 is engaged with a front end of the main body 3 so as to be able to rotate synchronously. The four support members 6 are supported within the median tube 11. The median tube 11 and the head tube 2 comprise a ratchet mechanism 12 which allows relative rotation between the head tube 2 and the main body 3 ( the median tube 11) only in a first direction. This ratchet mechanism 12 regulates the relative rotation between the head tube 2 and the main body 3 in another direction opposite to the first direction.
FIG. 8 is a vertical cross-sectional view illustrating the head tube 2. As shown in FIG. 8, the head tube 2 is made of an ABS resin (a synthetic copolymerization resin of acrylonitrile, butadiene and styrene). The head tube 2 has a tubular shape and an opening 2a for causing a front side portion of the tubular member 1 to appear on the front end. The head tube 2 comprises therein a receiving zone 2b for receiving the four cartridges 10. Any one of the four tubular elements 1, which are arranged inside the receiving zone 2b, is exposed from the opening 2a forward by the operation of a user.
On a front side of an outer circumferential surface of the head tube 2, an inclined surface 2c is disposed inclined so as to taper forwardly. An inner circumferential surface 2d on the front side of the head tube 2 is also tapered toward the front side. The inner circumferential surface 2d includes projections 2e which circumferentially have a large number of convex portions arranged side by side to engage the tubular members 1 in a direction of rotation (a direction about the axial line). These convex portions extend in the tilt direction of the inner circumferential surface 2d. These 2e projections extend across the entire area from one end to the other end in this tilt direction. The circumferential intervals of these 2nd projections diminish as it approaches the front side.
At a rear side portion of the inner circumferential surface of the head tube 2, a concave-convex portion 2f, which is a portion constituting the ratchet mechanism 12, is disposed. The concave-convex portion 2f has circumferentially twenty-four irregularity portions, which are arranged side by side and extend in the axial direction over a predetermined length. At the rear of the concave-convex portion 2f in the inner circumferential surface of the head tube 2, annular convex portions 2g, annular concave portions 2h and annular concave portions 2j are disposed. The annular convex portions 2g engage the medial tube 11 in the axial direction at the rear portion of the head tube 2. The annular concave portions 2h are positioned on the front side of the annular convex portions 2g. The annular concave portions 2j are positioned on the rear side of the annular concave portions 2h.
Fig. 9 (a) is a side view illustrating the median tube 11, and Fig. 9B is a vertical cross-sectional view illustrating the median tube 11. The medial tube 11 is an injection molded product made of POM (Polyacetal), and has an outer shape consisting of a stepped cylindrical shape. The median tube 11 comprises a front tube 11a, a central tube 11b and a rear tube 11c in this order from front to rear. The central tube 11b has an outer shape having a larger diameter than that of the front tube 11a. The rear tube 11c has an outer shape having a diameter smaller than that of the front tube 11a and the central tube 11b.
The front tube 11a comprises projecting resilient portions which constitute the other part of the ratchet mechanism 12 at two opposite positions to each other in an inner circumferential surface 11d. These projecting resilient portions engage the concave-convex portion 2f on the head tube 2 in the direction of rotation, and are disposed projecting outwardly in a radial direction. At peripheral regions of the resilient portions projecting into the tube before 11a, U-shaped slots 11f for communicating between the inside and the outside of the median tube 11 are formed. These slots 11f impart radial elasticity to the projecting elastic portions. The protruding resilient portions of the middle tube 11 are always brought into abutment with the concave-convex portion 2f on the head tube 2.
Fig. 10 is a cross-sectional view taken along the line AA of Fig. 1. As shown in Fig. 10, the concave-convex portion 2f on the head tube 2, which is the first part constituting the mechanism ratchet 12 includes inclined surfaces 2fl and side surfaces 2f2. The inclined surfaces 2fl incline relative to the inner circumferential surface of the head tube 2. The side surfaces 2f2 are formed to be approximately perpendicular to the inner circumferential surface of the head tube 2. The projecting resilient portions lie in the tube the median 11, constituting the other part of the ratchet mechanism 12, comprises an inclined surface 11a1 and a lateral surface 11e2. The inclined surface 11el tilts with respect to the outer circumferential surface of the median tube 11. The side surface 11e is formed to be approximately perpendicular to a line tangent to the outer circumferential surface of the median tube 11.
As shown in FIGS. 9 (a) and 9 (b), the notch 11f in the middle tube 11 comprises a pair of slots 11g and 11h, and a slot 11j. Slots 11g and 11b are drilled on both sides of the axially projecting resilient portion in the front tube 11a, and extend circumferentially. The slit 11j is drilled on a first side of the elastic protruding portion in the circumferential direction in the front tube 11a. Continuously with respect to slots 11g and 11b, slot 11j extends in the axial direction. A wall portion surrounded by the slots 11f in the front tube 11a forms an arm 11k having flexibility in the radial direction. Therefore, the projecting resilient portion 11a, which is disposed on an outer surface at a tip end of the arm 11k, has an elastic force (a thrust force) in the radial direction.
On an outer circumferential surface of the central tube 11b of the middle tube 11, projections 11m, an annular convex annular portion and a collar portion 11p are disposed. The projections 11m are removably engaged with the annular convex portions 2g of the head tube 2. The annular convex annular portion enters the annular concave portions 2j on the head tube 2 from the rear. The collar portion 11p is positioned at the rear of the annular convex annular portion. In the middle tube 11, a tube portion positioned on the front side with respect to the collar portion 11 is inserted into the head tube 2 from the rear.
On the rear tube 11c in the middle tube 11, projections llq intended to engage the main body 3 in the direction of rotation are formed to extend in the axial direction. These projections llq are formed at four positions arranged uniformly in the circumferential direction on an outer circumferential surface of the rear tube 11c. A convex portion 11r for engaging the main body 3 in the axial direction is formed at the rear of the collar portion 11p. This convex portion 11r extends circumferentially between the projections 11q.
A support member box 11a, which is a site for inserting the four support members 6 through the axial direction, divides the center tube 11 at the inner surface side of the collar portion 11p. This box of support members has circular bed openings for inserting the support members 6 through the axial direction at four positions arranged uniformly in the circumferential direction.
In the middle tube 11, the front tube 11a and the central tube 11b are inserted into the inside of the head tube 2 from the rear side. Next, the projecting resilient portions in the front tube 11 engage the concave-convex portion 2f of the head tube 2 in the direction of rotation. The projections 11m on the central tube 11b engage with the annular convex portions 2g on the head tube 2, and are connected to the annular concave portions 2h. In addition, the annular annular convex portion of the central tube 11b enters the annular concave portions 2j of the head tube 2.
Fig. 11 (a) is a vertical cross-sectional view illustrating the support member 6, and Fig. 11 (b) is an enlarged view of a front end of the support member 6 of the figure. 11 (a). The support member 6 has a fully cylindrical shape. As a material of the support element 6, the POM is for example used. The support member 6 includes a hole 6a, a movable body pressure portion 6b, and a cylindrical shaped tubular portion 6c. The hole 6a is disposed on the front side of the support member 6, and receives the movable body 5. The moving body pressure portion 6b presses on the movable body 5. The tubular portion 6c extends rearwardly from the moving body pressure part 6b.
The moving body pressure portion 6b of the support member 6 comprises two slots 6d. The slots 6d extend from the front end to the back side for a predetermined length so as to be mutually opposed at the inner circumferential surface of the movable body pressure portion 6b. With the moving body pressure portion 6b including the slots 6d, the elastic force of the resin of the support member 6 clamps the movable body 5 inwardly in the radial direction. These slots 6d allow the movable body pressure portion 6d to enlarge the diameter outwardly in the radial direction.
An extension portion 6g, which expands when viewed from the radial direction, is formed at a rear end of the slots 6d. This extension portion 6g suitably adjusts the resilient clamping force of the movable body 5 from the moving body pressure portion 6b. Projections 6f are formed in a spiral pattern on an inner surface 6e of the movable body pressure portion 6b. The projections 6f are disposed in three positions on the inner surface 6e of the support member 6 along the axial direction. These projections 6f are brought into abutment with the male thread 5a of the movable body 5 from the outside in the radial direction. It is also possible to engage the movable body 5 in the axial direction, and removably support the movable body 5 by means of the support member 6.
Four protrusions 6h are disposed at the interior of the tubular portion 6c of the support member 6. The projections 6h are disposed at four positions arranged uniformly in the circumferential direction, and extend in the direction axial. These protrusions 6h are arranged in the form of a rotational abutment for the movable body 5 with respect to the support member 6. The projections 6h comprise tapered surfaces 6n tapered towards the front end. These tapered surfaces 6n cause the protrusions 6h to have a shape by means of which the movable body 5 is easily inserted from the front side.
These projections 6h form an internal space of the tubular portion 6c of non-circular shape (cruciform shape) in terms of cross-sectional shape when the tubular portion 6c is cut at a plane perpendicular to the axial direction (see FIG. ). The tubular portion 6c further comprises through holes 6j having an ellipse shape extending in the axial direction, so as to pass through the interior and exterior of the support member 6. The through holes 6j support core pins so as to prevent the core pins from being tilted by injection pressure at the time of molding.
On an inner surface at the rear end of the support member 6, a projection 6m and an annular convex portion 6k are formed. The projection 6m engages with the sliding portion 8 in the direction of rotation. The annular convex portion 6k engages with the sliding portion 8 in the axial direction. The projection 6m is arranged on a straight line, as the projections 6h described above.
Figure 12 (a) is a perspective view illustrating the movable body 5, and Figure 12 (b) is a side view illustrating the movable body 5. The movable body 5 has an outer shape similar to a stick. As a material of the moving body 5, the POM is for example used. The movable body 5 comprises the male thread 5a and four grooves 5b, which extend in the axial direction, on the outer circumferential surface. The grooves 5b are arranged in four positions arranged uniformly in the circumferential direction.
The movable body 5 has a curved surface portion 5c where the male thread 5a is not formed on the surface at the back side. This curved surface portion 5c is arranged to wind around the movable body 5 when the movable body 5 reaches a forward limit. The insertion of the male thread 5a, which is positioned at the rear of the curved surface portion 5c, rearwardly of the projections 6f during attachment of the support member 6, prevents the movable body 5 from falling off the surface. Support member 6. The movable body 5 fully forms the male thread 5a in the axial direction. "Fully in the axial direction" includes the case where the male thread 5a is not partially formed, such as the case in which the curved surface portion 5c is formed in the middle of the movable body 5 in the axial direction, such as embodiment, in addition to the case in which the male thread 5a is formed on all parts of the movable body 5 in the axial direction.
The four grooves 5b on the movable body 5 are arranged to move the movable body 5 into the projections 6h of the support member 6 (see Figure 10). These grooves 5b are arranged to rotate the movable body 5 synchronously with the support member 6. These grooves 5b form the cross-sectional shape when the male thread 5a and the grooves 5b are cut at the plane perpendicular to the axial direction, in the non-circular form (the cruciform shape) corresponding to the internal space of the tubular part 6c of the support element 6.
A pitch of the male thread 5a in the movable body 5 (a distance between the threads of the male thread 5a in the axial direction) is, for example, 0.3 mm or more to 1 mm or less, and is preferably 0 , 6 mm. The usual pitch of the male thread is typically from 2 mm or more to 6 mm or less. As a result, the pitch of the male thread 5a is a fine pitch shorter than the pitch of the current male threads.
The male thread 5a and the grooves 5b in the movable body 5 are inserted from the front into the support member 6 so as to provide a clearance between the grooves 5b and the projections 6h. Engaging the projections 6f, which are arranged on the inner surface 6e of the support member 6, with the male thread 5a on the movable body 5 supports the movable body 5 through the support member 6 At this moment, the projections 6f push the male thread 5a from the outside in the radial direction, thus increasing a support force of the movable body 5 by the support member 6.
A columnar extraction portion 5d is disposed on the front end of the movable body 5 to extract the drawing material M located inside the tubular member 1 forwards. The extraction portion 5d comprises a lower surface 5e, which is positioned on the front end, a concave portion 5f, which is concave in transverse shape from the lower surface 5e, a circumferential circumferential surface 5g, and a tapered surface 5h, which tilts with respect to the bottom surface 5e and is continuous with the bottom surface 5e and the side surface 5g. The concave portion 5f is a hole for inserting a tool for rotating the movable body 5 during attachment of the movable body 5. The insertion of this tool in this concave portion 5f allows the movable body 5 to rotate during fixation and a similar work. The bottom surface 5e is a surface for extracting the drawing material M forwards.
Fig. 13 (a) is a side view illustrating the tubular member 1, and Fig. 13 (b) is a vertical cross-sectional view illustrating the tubular member 1. The tubular member 1 has an approximately cylindrical shape. As a material of the tubular element 1, PP (polypropylene) is used, for example. The coloring of the tubular element 1 with a color identical to the drawing material M or the configuration of the tubular element 1 in a transparent material ensures easy identification of the color of the drawing material M. A female thread is formed on the rear side of the inner circumferential surface of the tubular member 1 for moving the movable body 5 in the axial direction. As for the male thread 5a on the movable body 5, a pitch of the female thread 1a on the tubular element 1 (a distance between threads of the female thread 1a in the axial direction) is a fine pitch shorter than the pitch of threads current females.
At the front of the female thread 1a, in the inner surface of the tubular member 1, projections 1b extending in the axial direction are arranged in four positions arranged uniformly in the circumferential direction. These projections lb guarantee an obstacle for the drawing material M loaded in the tubular element 1 to go out. Although the number of protrusions lb is not particularly limited, the four protrusions 1b further effectively prevent the drawing material M from coming out. A concave groove 1a is disposed on the front side portion on the outer circumferential surface of the tubular member 1 to be engaged with the projections 2e of the head tube 2 in the direction of rotation. A plurality of concave portions extending in the axial direction at a predetermined length are arranged circumferentially side by side on the concave groove 1c.
Fig. 14 (a) is a side view illustrating the sliding portion 8, and Fig. 14 (b) is a perspective view illustrating the sliding portion 8. As a material of the sliding portion 8, an ABS resin is for example used. A color of the sliding portion 8 is for example identical to the color of the corresponding drawing material M. Slide the sliding portion 8 having the desired color forward a predetermined amount allows the drawing material M having the desired color to be exposed from the opening 2a of the head tube 2.
The sliding portion 8 has a shape extending in the axial direction. On a front end of the sliding portion 8, four claws 8a are arranged to be inserted into the tubular portion 6c of the support member 6 from the rear side. The claws 8a are each arranged in four positions arranged uniformly in the circumferential direction. The claws 8a each have an elastic force in the radial direction, and are releasably engaged with the annular convex portion 6k of the support member 6. The claw 8a includes an inclined portion 8k, which is tapered toward the before, and a concave part 8m. The concave portion 8m engages the annular convex portion 6k in the axial direction at a rear end of the inclined portion 8k. Providing the inclined portion 8k on this claw 8a forms the sliding portion 8 into a shape with which the sliding portion 8 is easily inserted into the support member 6.
The sliding portion 8 comprises a portion similar to a stick-shaped stick 8c around which the spring 9 is wound on the front side. At a rear end of the stick-like portion 8c is disposed a flat surface 8d projecting from the stick-like portion 8C outwardly in the radial direction. The stick-like portions 8c are inserted through bed openings on the support member housing 11 of the middle tube 11 in the axial direction. A first end of the spring 9 is brought into abutment with the flat surface 8d. Thus, the sliding portion 8 includes the stick-like portion 8c, which is disposed on the front side, and the flat surface 8d, which protrudes outwardly in the radial direction at the rear end of the portion. similar to a stick 8c, thus having a shape such that the spring 9 is easily fixed.
A projecting portion 8e is disposed on the rear side of the sliding portion 8 to pull and return the other sliding portions 8 rearwardly. This protruding portion 8e protrudes radially inwards in the main body 3, and extends in the axial direction. On the rear end of the sliding portion 8, a projecting portion 8f, a rear end portion 8g and a projecting portion 8j are disposed. The protruding portion 8f protrudes outwardly in the radial direction from the main body 3. The rear end portion 8g protrudes rearwardly at the rear end of the slidable portion 8, and is hooked to the main body 3. The projecting portion 8j projects inward in the radial direction of the main body 3, and has an inclined surface 8h. The protruding parts 8e of the other sliding parts 8 are brought into abutment with the inclined surface 8h. The support member 6 is engaged with the forward end of the sliding portion 8 configured as described above. At this time, engaging the claws 8a on the sliding portion 8 with the annular convex portion 6k on the support member 6 in the axial direction engages the support member 6 with the forward end of the sliding portion. 8 in the axial direction, thus guaranteeing a removable support of the sliding part 8.
Fig. 15 (a) is a vertical cross-sectional view illustrating the main body 3, Fig. 15 (b) is a side view illustrating the main body 3, and Fig. 15 (c) is a cross-sectional view, taken along line CC of Figure 15 (b). The main body 3 is an injection molded product made of ABS resin, and has a closed bottom cylindrical shape. Notched portions 3a extending in the axial direction to cause the protruding portion 8f on the sliding portion 8 to protrude outwardly are disposed on the rear side of the main body 3. The notched portions 3a are disposed in four positions arranged uniformly in the circumferential direction.
Flat portions 3b and protruding portions 3c are disposed at the notched portions 3a of the main body 3 inwardly in the radial direction. The flat portion 3d extends from the notched portion 3a inwardly in the radial direction. The projecting portion 3c extends in the axial direction at the flat portion 3b. The rear side of the projecting portion 3c extends to a lower surface 3d of the main body 3. As shown in FIG. 6, a displacement of the projecting portion 8f of the sliding portion 8 forward along notched portions 3a on the main body 3 moves the rear end portion 8g of the sliding portion 8 forward along the protruding portions 3c.
When the rear end portion 8g reaches the forward end of the protruding portions 3c, this rear end portion 8g enters the notched portions 3a inward in the radial direction, and the rear end portion 8g is hooked to the front ends of protruding portions 3c. While the rear end portion 8g of the first sliding portion 8 (e.g., the sliding portion 8A in Fig. 6) is hooked to the forward ends of the projecting portions 3c, the projecting portion 8e of the other sliding portion 8 (for example the sliding part 8B in FIG. 6) comes into close contact with the inclined surface 8h of the first sliding part 8.
As illustrated in Fig. 15 (a), concave grooves 3e, an annular concave portion 3f, and an annular concave portion 3g are disposed on the front side of an inner circumferential surface of the main body 3. The concave third grooves come into taken with the projections llq on the median tube 11 in the direction of rotation. The convex portion 11r on the median tube 11 engages with the annular concave portion 3f in the axial direction. The neck portion 11p on the middle tube 11 enters the annular concave portion 3g from the front. The concave third grooves extend from the annular concave portion 3g, which is positioned on the front end of the main body 3, rearward over a predetermined length. The concave third grooves are disposed in four positions arranged uniformly in the circumferential direction on the inner circumferential surface of the main body 3. The annular concave portion 3f extends circumferentially between the concave grooves 3e.
The four sliding parts 8 are inserted in the main body 3 from the front side. The protruding parts 8f on the sliding parts 8 protrude outwardly from the notched parts 3a. The median tube 11 enters the front end of the main body 3. When the median tube 11 enters the main body 3, the projections llq on the median tube 11 enter the concave grooves 3e of the main body 3. The convex portion 11r on the median tube 11 engages with the annular concave portion 3f of the main body 3 in the axial direction. Then, the collar portion 11p on the median tube 11 enters the annular concave portion 3g, and thus the median tube 11 is engaged with the main body 3 in order to be able to rotate synchronously.
As illustrated in FIG. 5 and FIG. 7, the spring 9 (the springs 9A to 9C) is wound around the stick-like portion 8c so as to provide clearance with respect to the outer periphery of the 8c a stick of the sliding portion 8. A first end (the front end) of the spring 9 is brought into abutment with the rear wall of the support element box They at the central tube 11. At the same time, the another end (the rear end) is brought into abutment with the flat surface 8d, which is positioned near the center of the sliding portion 8 in the axial direction. This spring 9 pushes the sliding portion 8 backwards.
The following describes operations of the power supply pen 100 configured as described above for use. The power supply pen 100, in an initial state shown in FIG. 5, positions the four sliding parts 8 at the rear end of the notched parts 3a on the main body 3, and positions the four tubular elements 1 inside the head tube 2. As shown in FIG. 6 and FIG. 7, in this state, a displacement of the sliding portion 8A forward along the notched portions 3a by a predetermined amount displaces the cartridge 10A, which is set in engagement with the sliding portion 8A in the axial direction, forwards, and the drawing material M1 is exposed forwards from the opening 2a to the head tube 2. At this moment, the entrance of the front lateral part of the tubular element IA in the inner circumferential surface 2d on the head tube 2 deforms the stick-like part 8c of the sliding part 8A so as to bend it with respect to the axial direction. ale, and the concave groove 1c of the tubular member 1A engages with the projections 2e on the head tube 2 in the direction of rotation. Then, the rear end portion 8g of the sliding portion 8A radially inwardly engages at the forward end of the protruding portions 3c on the main body 3.
In this state, for example, when the user relatively rotates the main body 3 in a first direction (e.g. clockwise) with respect to the head tube 2, the middle tube 11, the four sliding parts 8, the four support elements 6 and the four movable bodies 5 begin to rotate in the first direction. The tubular elements IB to 1D where the concave grooves 1c are not engaged with the projections 2e on the head tube 2 rotate in association with the relative rotation in the first direction.
On the other hand, the support member 6A connected to the tubular member 1 where the concave groove 1a is engaged with the projections 2e on the head tube 2 via the movable body 5A begins to rotate in the first direction in association with the relative rotation in the first direction. The tubular element IA where the concave groove 1a is engaged with the projections 2e on the driving tube 2 does not rotate at the same time as the rotation of the movable body 5A in the first direction, and the movable body 5A rotates. relative to the tubular element IA. As a result, the relative rotation in the first direction acts as a screwing action between the male thread 5a of the movable body 5 and the female thread la of the tubular member 1, and the movable body 5A begins to move forward. relative to the tubular element IA. When the lower surface 5e on the extraction portion 5d of the movable body 5A extracts the drawing material M1, which is loaded into the tubular member IA, forward, the movable body 5A and the drawing material M1 start to move together forwards relative to the tubular element IA.
As illustrated in FIG. 10, at the relative rotation in the first direction, the projecting resilient portions 43 constituting the ratchet mechanism 12 on the medial tube 11 engage the concave-convex portion 2f on the head tube 2 in the direction of rotation, and the elastic force through the notches llf radially pushes the elastic parts projecting links. This repeats the engagement and release (meshing and release of meshing) between the projecting elastic portions and the concave-convex portion 2f. That is, the realization of the relative rotation in the first direction with the projecting elastic parts and the concave-convex portion 2f engaged in the direction of rotation causes the inclined surfaces 11c and the projecting elastic portions. is in abutment with the inclined surfaces 2fl of the concave-convex portion 2f. In this state, the inclined surfaces 11a slide so as to move upwardly above the inclined surfaces 2f1.
After the projecting resilient portions have passed the convex portions on the concave-convex portion 2f, the projecting resilient portions engage the concave-convex portion 2f again in the direction of rotation. Accordingly, each time the projecting resilient portions and the concave-convex portion 2f engage and release from each other, a clicking sensation is imparted to the user. The concave-convex portion 2f has twenty-four irregularities arranged side by side in the circumferential direction; therefore, whenever the relative rotation is performed in the first direction by 15 °, the knocking sensation is provided to the user.
At the same time, when a user attempts to relatively rotate the main body 3 in the other direction (e.g., counterclockwise), which is a direction opposite to the first direction , with respect to the head tube 2, the side surfaces Ile2 on the projecting resilient portions lie, which constitute the ratchet mechanism 12, are brought into abutment with the side surfaces 2f2 on the concave-convex portion 2f, thereby regulating the relative rotation in the other direction. As a result, the head tube 2 and the main body 3 do not rotate relative in the other direction. That is, a rotational force (a torque) in the relative rotation in the first direction is set to be a force to ensure easy rotation, while a rotational force in the relative direction in the other direction is established to be a force through which rotation is not carried out easily. For example, with the outer diameter of the main body 3 designed at about 14 mm, the relative rotation torque in the first direction is set to be 0.1 N "m (Newton-meter) or less, and the torque Relative rotation in the other direction is set to be 0.2 N * m or more.
As shown in FIG. 6, in the state in which the forward displacement of the sliding portion 8A moves the tubular member IA forward, and the drawing material M1 is exposed forward, moving the 8B another sliding portion forward of the predetermined amount brings the projecting portion 8e on the sliding portion 8B close to the inclined surface 8h of the sliding portion 8A abuts with the inclined surface 8h of the sliding portion 8A. The abutment of the projecting portion 8e on the sliding portion 8B with the inclined surface 8h of the sliding portion 8A removes the sliding portion 8A outwardly in a radial direction, thereby releasing the rear end portion 8g of the portion sliding 8A of the front end of the protruding parts 3c. The pushing force exerted by the spring 9A towards the rear pushes and brings back the sliding portion 8A towards the rear end position of the notched parts 3a.
As described above, this pen 10 comprises the ratchet mechanism 12 which allows the relative rotation between the head tube 2 and the main body 3 in the first direction, and regulates the relative rotation in the other direction. The ratchet mechanism 12 comprises the projecting resilient portions, which protrude from the outer surface on the front tube 11a (the tube portion) of the middle tube 11, and the concave-convex portion 2f on the inner surface of the tube. 2. In this ratchet mechanism 12, the concave-convex portion 2f on the inner surface of the head tube 2 is movable relative to the projecting resilient portions on the outer surface of the front tube 11a in the axial direction.
The projections 11m disposed on the outer surface of the central tube 11b (the tube portion) in the middle tube 11 removably engage the annular convex portions 2g, which are disposed on the inner surface of the head tube 2, in the axial direction. Thus, the median tube 11 has a dual function of ratchet mechanism 12 by the projecting resilient portions 11c, and can be removably secured by the projections 11m with the first component. Therefore, the head tube 2 can be removably attached to the middle tube 11 in the axial direction, thereby ensuring easy disassembly by removing the head tube 2 from the middle tube 11. Accordingly, in the case of a failure of the component such as the inner cartridge 10, the user can remove the head tube 2 and easily replace the internal component. With the help of the feeding pen 100, the several drawing materials M are stored in the head tube 2. The head tube 2 comprises the several sliding parts 8 connected to the several respective drawing materials M, and can slide relative to the main body 3 of the predetermined amount. Of the plurality of sliding portions 8, the forward displacement of any given sliding portion 8 relative to the main body 3 of the predetermined amount moves any given pattern material M forwardly. As a result, the several drawing materials M can be stored in the feeding pen 100, and any given drawing material M can be moved forward for use. That is to say that the feeding pen 100 comprises the several tubular elements 1, movable bodies 5 and support elements 6. The feeding pen 100 comprises the several sliding parts 8 connected to the several respective support elements 6, and being able to slide relative to the main body 3 of the predetermined quantity. Among the several sliding parts 8, the forward displacement of any given sliding part 8 with respect to the main body 3 of the predetermined quantity exposes any given drawing material M from the head tube 2. In this state, relative rotation of the head tube 2 and the main body 3 in the first direction moves the drawing material M forwards. This allows the feeding pen 100 to internally receive the several drawing materials M. Even if the several drawing materials M are received, this also ensures the maintenance of the feeding pen to a small diameter.
The feeding pen 100 charges the drawing materials M towards the inside of the tubular elements 1, and receives the moving bodies 5 inside the tubular elements 1 and the support elements 6. The movable body 5 completely forms the male thread 5 a in the axial direction. This guarantees a screwing and a support of the male thread 5a in any given position by the tubular element 1 and the support member 6. The male thread 5a of this movable body 5 is screwed into the female thread 1a on the inner surface of the tubular element 1, and is brought into abutment with the projections 6f, which are arranged at the rear of the tubular element 1, on the inner surface 6e of the support element 6 from the outside.
Accordingly, as shown in Fig. 16 (a) and Fig. 16 (b), which are the vertical cross-sectional views of the tubular member 1, the movable body 5, and the support member 6, the tubular element 1 screwed with the movable body 5 and the support member 6 supporting the movable body 5 can be arranged in the axial direction, thereby limiting a radial enlargement of the supply pen 100. Therefore, this power supply pen 100 allows get a small diameter 100 power pen. With the aid of the feeder pen 100, for example, the inside diameter of the thread pitch of the female thread 1a on the tubular member 1 is slightly larger than the inside diameter of the projection 6f on the support member 6. With regard to this, although the fine clearance is formed between the male thread 5a of the movable body 5 and the screw thread of the female thread 1a, a clearance is not formed between the male thread 5a and the projections 6f, thus guaranteeing always bring the projections 6f in abutment with the male thread 5a.
The projections 6f of the support member 6 are formed in a spiral pattern on the inner surface 6e of the support member 6. This allows the projections 6f to be engaged with the male thread 5a along the forming the male thread 5a, thus ensuring an increase in the support force of the male thread 5a by the support member 6. The support member 6 comprises the slots 6d extending in the axial direction from the part of the end on the front side. The provision of these slots 6d ensures the increase of the radial elastic force at the end portion on the front side of the support member 6. This ensures the increase of the radial support force by the element 6, thereby guaranteeing even more reliable limiting of the output of the movable body 5 from the support element 6.
Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and variants may be made without departing from the scope of the invention or applications to other elements can be implemented. That is, the configuration of the respective components constituting the power supply pen 100 can be suitably modified without departing from the scope of the invention.
For example, as shown in FIGS. 8 to 9 (b), the embodiment described above describes the example in which the projecting resilient portions lie in the middle tube 11 and the concave-convex portion 2f on the tube 2 constitute the ratchet mechanism 12, and the projections 11m, which are arranged on the outer surface of the median tube 11, and the annular convex portions 2g, which are arranged on the inner surface of the head tube 2, are removably taken in the axial direction. However, as a supply pen according to a modification, annular convex portions removably engaging the projecting resilient portions 11c, which constitute the ratchet mechanism 12, in the axial direction, can be arranged on the inner surface of the head tube 2. That is to say that the supply pen according to this modification comprises the tubular main body 3, the head tube 2 and the median tube 11. The head tube 2 is engaged with the main body 3 to be able to rotate relatively. The median tube 11 has the tube portions (the front tube 11a and the central tube 11b) inserted inside the rear side of the head tube 2. The middle tube 11 is positioned between the head tube 2 and the main body 3. The median tube 11 is engaged with the head tube 2 for relative rotation. The relative rotation between the head tube 2 and the main body 3 in the first direction moves the drawing material M forwardly within the head tube 2. The ratchet mechanism 12 allows the relative rotation between the tube head 2 and the main body 3 in the first direction. The ratchet mechanism 12 regulates the relative rotation in the opposite direction to the first direction. The ratchet mechanism 12 includes the projecting resilient portions and the concave-convex portion 2f. The projecting resilient portions protrude from the outer surface onto the tube portion of the middle tube 11, and have elasticity in the radial direction. The concave-convex portion 2f is disposed on the inner surface of the head tube 2. The concave-convex portion 2f engages with the resilient portions projecting to be movable in the axial direction, and to be rotatable. The resilient projecting portions releasably engage the annular convex portion disposed at the inner surface of the head tube 2 in the axial direction.
As described above, with the aid of the feeder pen according to this modification, the projecting resilient portions releasably engage the annular convex portion disposed on the inner surface of the head tube 2 in the axial direction. Accordingly, the projecting resilient portions, which constitute the ratchet mechanism 12, removably engage the annular convex portions on the inner surface of the head tube 2. Thus, the projecting resilient portions also have the function to be removably attached. Thus, the projecting resilient portions may have the function of being removably attachable. This eliminates the projections 11m.
The embodiment described above describes the example in which the annular convex portions 2g, the annular concave portions 2h, which are positioned on the front side of the annular convex portions 2g, and the annular concave portions 2j, which are positioned on the rear side of the annular convex portions 2g are disposed on the inner surface of the head tube 2. However, the annular concave portions 2h or the annular concave portions 2j may be omitted. That is, at least any one of the front side of the annular convex portions 2g and the back side of the annular convex portions 2g can be formed into flat surfaces.
The embodiment described above describes the example in which the projections 11m, which are arranged on the outer surface of the median tube 11, and the annular convex portions 2g, which are arranged on the inner surface of the head tube 2, removably engage with each other in the axial direction. However, aspects of the shape and arrangement of the projections 11m on the median tube 11 and the annular convex portions 2g on the head tube 2 are not limited to the example described above. Further, instead of the projections 11m and the annular convex portions 2g, an annular convex portion may be formed on the outer surface of the medial tube 11, and a protrusion may be formed on the inner surface of the head tube 2. This convex portion The annular ring on the outer surface of the median tube 11 can be releasably engaged with the protrusion on the inner surface of the head tube 2 in the axial direction. The embodiment described above describes the example in which the median tube 11 comprises the front tube 11a and the central tube 11b, but however suitably changing the shape of the median tube is also possible.
As illustrated in FIGS. 11 (a) and 11 (b), the embodiment described above describes the example where the provision of slots 6d to the support member 6 increases the radial elastic force at the front end. of the support member 6. This support member 6 may further comprise an elastic portion which provides an elastic force external to the movable body 5, which is internally supported by the support member 6. Specifically, for example, a portion The circumferentially extending annular concave may be formed between the plurality of slits 6d of the outer surface of the support member 6, and an O-ring, which is an elastic body, may be introduced into this annular concave portion. In this case, the introduction of the O-ring into the annular concave portion clamps the movable body 5 supported by the support member 6 inward in the radial direction, thereby further reliably preventing the moving body 5 from out of the support member 6. That is, the outwardly elastic force in the radial direction through the resilient portion provides a further increase in the support force by the elastic element. support 6.
The embodiment described above describes the example where the projections 6f on the support member 6 are formed in the spiral pattern on the inner surface 6e of the support member 6. However, the aspects of the form and arranging the projections formed on the inner surface 6e of the support member 6 are not limited to the example described above. For example, protrusions in a pattern other than the spiral pattern may be disposed in a plurality of positions along the axial direction on the inner surface 6e of the support member 6. In this case also, the plurality of projections disposed along of the axial direction each press the male thread 5a of the movable body 5 outward in the radial direction. This ensures that the male thread 5a is less likely to exit the support member 6. Thus, the plurality of projections disposed along the axial direction can increase the resistance against the output of the male thread 5a.
Further, the embodiment described above describes the example where the projections 6f on the support member 6 are disposed at the three positions along the axial direction on the inner surface 6e of the support member. 6. However, the projection (s) 6f may be disposed in one position, two positions, or four or more positions along the axial direction.
As illustrated in FIG. 13 (b), the embodiment described above describes the example where the projections 1b are arranged in four positions arranged uniformly in the circumferential direction on the front of the female thread 1a in the inner surface of the tubular element 1. These projections 1b prevent the drawing material M loaded towards the tubular element 1 to come out. However, measures to prevent the drawing material M from coming out can be taken with elements other than the projections 1b. For example, instead of protrusions lb, steps to increase a coefficient of friction may be taken on the inner surface of tubular member 1. Alternatively, measures to prevent exit may be taken by forming the inner surface of the tubular element 1 in a non-circular shape, such as a polygonal shape.
The embodiment described above describes the feeding pen 100, a multiple pen, which comprises the drawing materials M1 to M4 having different colors from each other. However, the power supply pen may comprise drawing materials having different thicknesses from each other. In addition, the power supply pen may include several drawing materials whose materials or applications are different from each other. The number of drawing materials is not limited to four, but can be two, three, five or more.
In addition, the power supply pen according to the present invention may not be a multiple pen. That is, the power supply pen according to the present invention may each include from the drawing material, the tubular member, the movable body and the support member.
