    [0001] The present invention is in the field of water sports which the practitioner uses a traction force for his movements, such as the muscle energy of a human or wind energy or a vehicle or engine, namely the so-called sports " gliding ", in particular using a boat or a draft sail, preferably kitesurfing. The present invention will find a preferential application, but not limited to kitesurfing, but may be adapted for the practice of wakeboarding, windsurfing, windsurfing and surfing, or even kayaking. The invention specifically relates to a foil device, intended to be secured and extend under the underside of a boat or a board for the practice of such a nautical sport. In known manner, a foil is derived from the Anglo-Saxon term "hydrofoil", hereinafter referred to as "foil". A foil is a wing that moves in and in contact with water, whose hydrodynamic profile transmits to its support a lift force orthogonal to the direction of movement of the board. Such foil is generally provided with at least one vertically extending mast, removably attached at its upper end to the underside of the board and connected at its lower end to a wing. This latter extends laterally, generally symmetrically on either side of a fuselage, relative to the plane of said mast, aligned with the longitudinal median plane of said board. Said wing may consist of a single element but it is generally composed of at least two separate portions, anterior and posterior, making it possible to obtain lever arms and moments necessary for longitudinal stability for pitching and lateral for the roll. Most existing foils consist either of a single block constituting the mast and the fuselage, the wings being removable, or of a mast and a block constituting the fuselage and the wings, said block being removable. If this monobloc embodiment confers a high mechanical strength to this foil, it poses a problem for its transport and storage. This one-piece foil has bulky dimensions, making it difficult and tedious transport, and its 5 assembly and disassembly operations in attachment with the board. It has been imagined to separate the different elements constituting a foil, namely the mast, the fuselage and the wing portions, and to fix them together removably. Thus, once disassembled, the various elements have a smaller footprint, facilitating their storage and transport. However, a problem lies in the removable attachment of the elements to each other and the orientation of the fastening means used. Indeed, the anterior and posterior portions 15 of the wing are attached to the mast, at the fuselage, reciprocally at the front and rear of the latter, which then with its fuselage an inverted T shape in the median plane of the foil, namely the vertical plane. This attachment is made by screwing, transversely to the plane of each wing portion, from above or below said portions. The attachment axis is then in a vertical plane oriented orthogonally with respect to the direction of movement of the foil and substantially according to the lift forces applied by each portion of the foil being displaced. As a result, these stresses are applied at each screw, mechanically deforming this precise junction point. These stresses cause deterioration of this attachment over time, which can cause them to rupture and tear the wing portions. Moreover, in the case of several screws, the assembly and disassembly of the portions of the wing of such a foil, remain tedious and must be carried out methodically and with care, especially concerning the assembly to ensure good fixation and good positioning of the elements between them, imparting the desired hydrodynamic characteristics.
    [0002] An example of such a foil is described in US 2005/0255764. As mentioned above, such a foil comprises a mast at the lower end of which extends a fuselage, the assembly being shaped T inverted. A front segment of the fuselage receives an anterior portion of a wing by screw-fastening from above, while a rear segment receives a rear wing portion by fastening by screwing from below. The present invention aims to overcome the disadvantages of the state of the art, by proposing a modular foil, consisting of several removable elements, assembled and fixed together. The invention lies in the fact that the elements, once assembled, are locked along the longitudinal axis of the fuselage of the foil, namely substantially in the direction of movement of said foil. To do this, the present invention relates to a foil device comprising at least one wing and at least one mast equipped in the upper part with fixing means and provided in the lower part of a section from which said wing extends, said section comprises a central segment connected to the lower part of said mast; at least a first removable segment secured to at least a first portion of said wing; said section further comprising means for assembling at least a first end of said central segment with a butted end of said first segment, said assembly means are in the form of at least one pair consisting of a male part and a female part cooperating in interlocking, each pair being formed at the abutting ends of said segments; said device further comprising locking means of said first segment with at least said central segment. Such a device is characterized in that said locking means extend along the longitudinal axis of said section and provide locking in at least one direction of said longitudinal axis and in that said male part comprises at least one inclined wall intended to cooperate with a complementary inclined wall formed at said female part. This longitudinal locking completely changes the mechanical strength of the fastener between the assembled segments 5 of the section forming the fuselage. Indeed, with a component of the locking force extending along the longitudinal axis of the fuselage, the pairs generated by the wing during the movements are reflected differently, directly at the nesting and not at the level of the fastener 10 itself. In addition, the invention provides for improved assembly between the abutting segments by providing interlocking by means of male and female portions having inclined walls for slidingly cooperating together, providing improved guidance and centering of the segments. thus assembled, limiting the game once locked. In addition, according to other additional nonlimiting features, said section may comprise at least one second detachable segment integral with at least one second wing portion, similar assembly means and said locking means mutually ensuring assembling and locking an opposite second end of said central segment with a butted end of said second segment. The two abutting ends of the first and second segments may have their respective male portions, while the first end and the second opposite end of said central segment may include the corresponding female portions. Said locking means may comprise at least one rod extending at least in part along at least said first segment and cooperating in lock with said central segment. Said locking means may comprise at least one rod cooperating in insertion within a first housing 35 formed along said first segment from an opposite free end to the abutting end, said rod cooperating in locking at least through the first end of said central segment with another of the segments of said section. Said locking means may comprise a single rod cooperating in insertion within a first housing formed along said first segment from an opposite free end to the abutting end and within a central recess arranged along said central segment from its first end to its second end, said rod cooperating in locking within the abutting end of said second segment. Said rod may have a distal end cooperating abutting against said opposite free end of said first segment. Said rod may comprise at least one end thread so as to cooperate with a complementary thread formed in the abutting end of the central segment or of said second segment. In addition, the assembly and attachment are made more precise, preventing misalignment and setting of the elements together. Other characteristics and advantages of the invention will emerge from the following detailed description of non-limiting embodiments of the invention, with reference to the appended figures, in which: FIG. 1 schematically represents a perspective view of an embodiment of a foil device according to the invention, in assembled position; FIG. 2 diagrammatically represents an exploded perspective view of FIG. 1, showing this embodiment of the foil according to the invention in the disassembled position; FIG. 3 diagrammatically represents a vertical profile view of the embodiment of FIGS. 1 and 2, in the assembled position of said foil, showing by transparency the assembly of the various elements constituting it; - Figure 4 shows schematically a view in a longitudinal middle vertical section of said embodiment of the foil device, in the disassembled position; FIG. 5 schematically shows a perspective view of a detail of the foil according to a first embodiment, showing the male part of an end of a segment; - Figure 6 schematically shows a view similar to Figure 5, according to another embodiment; FIG. 7 schematically represents a view similar to FIG. 5, according to a different embodiment; and - Figure 8 shows schematically a view similar to Figure 5, according to another different embodiment. The present invention relates to a device 1 foil. Such a foil 1 comprises at least one wing, preferentially but not limitatively at least one front wing 2 and at least one rear wing 3. Each wing 2,3 may comprise several portions, preferably two, extending symmetrically from each other. on the other hand, to the right and to the left, of the vertical median plane of said foil 1. Each wing 2, 3 has an aerodynamic or hydrodynamic profile, the shape of which provides lift during the displacement of the device 1. Said foil 1 also comprises the least one mast 4. The latter extends vertically or substantially vertically. Such a mast 4 may comprise several distinct branches, grouped together or separated, over all or part of its length. It may have any shape, preferably a shape having an aerodynamic or hydrodynamic profile. According to the preferred embodiment, the mast 4 has an elongated and flattened shape along its width, or tapered, with a generally cross-sectional section in accordance with a transverse horizontal or substantially horizontal plane. This mast 4 is intended to cooperate in fixing, removably, from the underside of a watercraft, preferably a board for the practice of a water sport, as defined above. To do this, the mast 4 is equipped in the upper part with fastening means (not shown). These means ensure the maintenance of the foil 1, but also the transmission of the lift to lift said board during its movements in contact with and above the water.
    [0003] Furthermore, said mast 4 is provided in the lower part of a section 5. The latter constitutes the fuselage of the foil 1. It extends along an axis in or parallel to the longitudinal vertical median plane of said foil 1, from the front towards the rear. It generally has an elongated spindle shape, of circular or ovoidal section. Said section 5 serves as support for the wing, from which it extends. Preferably, each wing 2,3 extends laterally, projecting, symmetrically on either side, to the right and left, relative to the longitudinal vertical median plane of said section 5. Advantageously, said section 5 is divided into several segments, at least two. It will be noted that each wing 2, 3 is integral with a portion of said section 5. In other words, during manufacture, the portion of the section 5 supporting each wing portion 2, 3 consists of a single portion. and even piece. First, the section 5 comprises a central segment 6 connected to the lower part of said mast 4. The mast 4 can be connected to said section 5 at said central segment 6 permanently or removably. In particular, the lower end of the mast 4 can be shaped and dimensioned so as to cooperate complementarily with the central segment 6 of said section 5. This cooperation is effected in particular by interlocking, said mast 4 forming a male part to be inserted within a female part formed in said central segment 6, or vice versa. A specific attachment can then ensure the interlocking of these two parts. Other segments are butted at said central segment 6, removably attached. In particular, the section 5 comprises at least a first removable segment 7 secured to at least a first portion of said wing. In this case, the section 5 is divided into only two segments, for example the central segment 6 connected to the mast 4 and another segment abutting at the front or rear. Therefore, if the first removable segment 7 is at the front, it supports the front wing 2 and the rear wing 3 is secured to the central segment which extends to the rear end of the foil 1. Conversely if the first removable segment 7 is located at the rear, then the rear wing 3 is removable while the front wing 2 is fixed, secured to the central segment 6 which extends to the front end of said foil 1. In order to obtain this removable nature of the segments 6, 7 of the section 5, said section 5 comprises means 8 for assembling at least one end of said central segment 6 with a butted end of said first segment 7 The assembly means 8 ensure the junction of the segments between them at their abutting end, and their maintenance. This maintenance results in the blocking displacement of each removable segment when it is assembled on the central segment 6, outside the nesting direction for assembling and disassembling the segments. This interlocking direction extends along the longitudinal median axis of said section 5. In other words, once assembled, the segments can not move laterally or turn relative to each other, for example. relative to the longitudinal median axis of the section 5. The assembly means 8 may be in the form of at least one pair consisting of a male portion 80 and a female portion 81 cooperating interlocking. Each pair 30 is formed at the abutting ends of said segments. Preferably, the male end 80 is protruded at the end of the removable segment, namely the first segment 7, while the female portion 81, recessed, is formed within the adjacent end of the central segment 6 The opposite is also possible.
    [0004] Said male 80 and female 81 parts have complementary dimensions and shapes, with the game, allowing their interlocking. Several examples of shapes are shown in FIGS. 5 to 10. In particular, the male part 80 may have a polyhedral shape, in particular a truncated pyramidal shape, with a triangular, rectangular, square or polygonal base, or even such as a star. The polygon section, with ridges, locks, especially in rotation, segments between them. Two examples are shown schematically in Figures 5 and 6. Preferably, said male portion comprises at least one inclined wall for cooperating with a complementary inclined wall formed at said female portion. According to a particular embodiment, the male portion 80 has at least one inclined outer wall 86, decreasing from the inside towards the outside of the segment. This inclined outer wall 86 is intended to cooperate with an inner wall also inclined, formed within the female portion 81 of the abutting end, convergently from the outside to the inside of the adjacent segment. Thus, during locking, the inclined walls slide against each other, providing improved guidance, centering and positioning of the interlocking segments, once the abutting ends assembled. In addition, in locking, the interlocking of these inclined walls ensures a perfect connection between the segments. As shown in Figure 7, the male portion 80 may have a frustoconical shape and the inclined outer wall 86 is constituted by the outer wall. The female part 81 then has a reverse cone frustum, of complementary dimensions, whose peripheral inner wall then forms said inclined inner wall. In addition, but not exclusively, the locking in rotation can then be effected by at least one lug 82, preferably two, arranged projecting, off-axis, at the end of the male part or at least one side and cooperating within a hole or blind hole, arranged vis-à-vis the breast or one side of the female part. According to the embodiment shown in FIG. 5, the male portion 80 has a truncated pyramidal shape with a square base. The outer faces then each constitute an inclined outer wall 86. According to the embodiment shown in FIG. 6, the edges of the truncated pyramid of the previous embodiment are rounded. These edges with the outer faces 10 together constitute the inclined outer walls 86. These embodiments require a section 5 whose interior is solid, in order to provide the female part 81, or receiving an additional piece, such as a cover , on which are provided the male 80 and female 81. In another embodiment, as shown in Figure 8, the male portion 80 may be formed on a hollow or tubular body of the section 5. Therefore, it presents itself in the form of arches projecting over a portion of the perimeter of the end of a segment. The female part 81 then consists of complementary notches. In addition, in order to improve interlocking locking during locking and proper positioning of the segments together, each arc may have an inclined inner wall 85, in a frustoconical-type curvature, intended to cooperate against a complementary outer wall arranged at the corresponding female part 81. Thus, the inclination of the inner and outer walls 86 of the male 80 and female 81, provides a perfect assembly, without play, once the segments locked. As such, an essential feature of the present invention lies in the locking of the assembly of the segments of said section 5. This interlocking locking of the assembled segments is performed according to a component oriented along the longitudinal axis of said section 5. In in other words, the locking does not take place transversely or orthogonally, but longitudinally with respect to section 5. To do this, said foil device 1 comprises means 9 for locking said first segment 7 with at least said central segment 6. In addition, said locking means 9 extend along the longitudinal axis of said section 5 and provide locking in at least one direction of said longitudinal axis. In other words, the locking means 9 cooperate with each segment to block their interlocking. These means 9 have a substantially orthogonal component with respect to the median axis of the mast 4, namely that their horizontal or substantially horizontal component (along the longitudinal median axis of the section 5) is greater than the vertical or substantially vertical component ( along the longitudinal median axis of said mast 4). Preferably, the locking means 9 have a single and only horizontal or substantially horizontal component. The section 5 can be divided into three segments. According to a specific embodiment, not shown, an intermediate segment may be interposed between the central segment 6 and the first segment 7. In other words, the first segment 7 is subdivided into two. It is also possible to subdivide each segment into other additional sub-segments, without limitation of numbers. Thus, depending on the level or climatic conditions, it is possible to adapt the length of the section 5 and the fuselage of the foil 1, by removing or adding a segment, or by exchanging segments of different lengths. In general, said section 5 comprises at least one second removable segment integral with at least a second portion of said wing.
    [0005] According to the preferred embodiment, visible in FIGS. 1 to 3, these three segments are the front segment 7, the center segment 6 and the rear segment 10. The second segment 10 can receive the rear wing 3 while the first segment 7 receives the front wing 2, as visible in Figures 1 to 3 (or vice versa). The abutment of the central segment 6 and the second segment 10 is also performed by means of assembly. These are similar to the means previously described. In this configuration, the abutting ends of the first 6 and second 10 segments have their respective male portion 80, while the first end and the second opposite end of said central segment 6 comprises the corresponding female portions 81. The reverse is also possible, at that the central segment 6 has the male parts 80 at each end, while the segments 7,10 have the female parts 81 on one of their end intended to be abutted with said central segment 6. These similar assembly means and said locking means 9 reciprocally assemble and lock an opposite second end of said central segment 6 with an abutting end of said second segment 10. In other words, the locking means 9 make it possible to fix between them two segments. . This locking is always effected along the longitudinal median axis of the section 5. According to the general embodiment with a minimum of two segments, said locking means 9 comprise at least one rod 11 extending at least in part along at least said first segment 7 and cooperating in lock with said central segment 6. In other words, the rod 11 passes through the assembled ends of the abutting segments, to apply a clamping force in the longitudinal interlocking direction. According to the three-segment front, middle and rear embodiment, this lock passes through the central segment 6.
    [0006] To do this, said locking means 9 comprise at least one rod 11 extending from the first segment 7 to integrally pass through the central segment 6, through a central housing 12, and to be inserted within the second segment 10. This configuration can include two rods 11, which are housed at one end, on either side within the central segment 6, through one or more central housings 12, and at the level of the opposite end within housing specific to each segment, front and rear. As mentioned above, this rod 11 can extend from the front segment to the rear segment, or vice versa. In addition, each rod 11 comprises at least one end thread so as to cooperate with a complementary thread formed in the abutting end of the central segment or of said second segment. According to another embodiment, said locking means 9 comprise at least one rod 11 cooperating in insertion within a first housing 13 formed along said first segment 7 from an opposite free end to the abutting end. In addition, said rod 11 cooperates in locking at least through the first end of said central segment 6 with another of the segments of said section 5, 25 as the second segment 10. In this configuration, the rod 11 is inserted and locked in position. interior of the first housing 13, in the form of a blind hole. It protrudes from this hole through the central segment into and along its central housing 12, to open at the opposite end and lock inside the second segment 10. More precisely, depending on the mode. preferred embodiment, visible in Figures 2 to 4, said locking means 9 comprise a single rod 11 cooperating in insertion within a first housing 13 formed along said first segment 7 from an opposite free end to l end abutting and within a central housing 12 formed along said central segment 6 from its first end to its second end, said rod 11 cooperating in lock within the abutting end of said second segment 10. In this configuration, the first housing 13 is through and the rod 11 is slidably introduced from one end of said first segment 7 to cross it integrally, go out and work erser integrally the central segment 6, to unclog and be inserted in lock in the second segment 10. Thus, it is possible to lock and unlock the rod 11 by its free end from the distal end of the first segment 7. In this case, said rod 11 has a distal end cooperating in abutment with said opposite free end of said first segment 7. To do this, the first housing 13 may comprise, at its free end, an annular hook 16 intended to receive the distal end of the stem 11 at which is formed an annular ring 14. The latter then cooperates in interlocking within said stall 16, limiting its travel along and inside the segments through which it passes. In particular, said distal end may include a removable tip 15. The latter may be fixed by screwing on said annular ring 14, which then internally has a complementary thread. Furthermore, at its opposite end, said rod 11 may have a thread intended to cooperate with a complementary tapping formed in the most distant segment, namely the central segment 6 in the case of only two segments. attached together, or the second segment 10 in the case of three butted segments. In addition, it will be noted that the rod 11 can pass through the male 80 and female 81 parts, as can be seen in FIGS. 5 to 8. The longitudinal housings of each segment then pass through the corresponding male 80 and female 81 portions. Furthermore, the various elements constituting the foil 1, namely the mast and the segments of the section 5, may be made of any type of material, preferably carbon fiber. The rod 11 and its tip 15 may be made of metal, preferably stainless. In addition, metal or composite inserts may be introduced into the segments, in their housing, so as to cooperate by screwing with said rod 11. Thus, according to the embodiment shown in Figures 1 and 2, during assembly foil 1, we just abut and assemble the first segment 7 located at the front and the second segment 10 located at the rear, by fitting their male part 80 with the female parts 81 of the central segment 6. Then, we introduce the rod 11 from the front end, namely the distal end of the first segment 7, to slide along the section 5 thus assembled, until cooperating within the housing 17 of the second segment 10 located at the back. The rod 11 is screwed, enclosing the segments 6,7,10 and locking their assembly by interlocking. Finally, the tip 16 is screwed onto the front end of the rod 11. The disassembly of such foil 1 is done by repeating the previous steps inversely. The foil device 1 according to the invention therefore allows to quickly and simply assemble the segments to form the section 5, free of any adjustment or mounting error. In addition, the longitudinal locking provides improved blocking of the segments between them, limiting the wear of fasteners and interlocking parts. Maintaining longitudinally locking provides a better distribution of the torques applied during use of the foil 1, offering better resistance to the mechanical stresses it undergoes and increasing its life. In addition, no fastener crosses laterally or radially the walls of the section 5, providing a streamlined, more aerodynamic or hydrodynamic. Finally, the inclination of the interlocking parts ensures a perfect connection between the segments. Thus, the inner and outer wall inclination of the male and female parts for assembly and interlocking, combined with longitudinal locking, provides improved securing of the segments together, improving the rigidity, strength and accuracy of the foil. 1 according to the invention.
