    [0001] TECHNICAL FIELD AND STATE OF THE ART The present invention relates to the field of water sports, and in particular to the equipment of boats used in the context of water sports. The invention proposes an anti-drift device connected to the outer surface of watercraft, such as, for example, windsurfing or kitesurfing fins, and belongs to the field of load-bearing wings also known as Anglo-Saxon " hydrofoil ". Such a load-bearing wing is mainly used to facilitate the start of planning (sinking action) of a watercraft, such as kitesurfing: that is to say, its role is to improve the lift and, by subsequently, encourage the release of water from the boat, even in light winds. The load-bearing wing must also allow the practitioner to easily control his heading. The term "fin" means, in the remainder of this description, the carrying planes and spoilers, that is to say stabilizers, necessary for the proper functioning of a load-bearing wing. The term "fuselage" refers to the elongated part that connects the different carrying planes and spoilers between them. The fuselage is itself connected to a central pillar, called "mast", which mast must be positioned at one end to the watercraft. According to the prior art the fuselage and the mast are arranged in a fixed or removable manner, so as to materialize T-shaped supporting wings. For this type of airfoil, it is important to have the wings removable one by one from the fuselage. , because a fuselage system with fixed blades causes the following problems: - a large size when transporting this type of equipment; - an obligation to change the set in case of breakage or defect on a single part; - A limitation of the possible configurations, because this fixed assembly does not allow the use of different fins for a given carrier plane, and vice versa; and a difficulty of manufacturing these complex parts in a single part.
    [0002] However, using a system with removable fins requires the presence of fasteners fins on the fuselage. These fasteners must be strong, simple to use, accurate and not to damage the hydrodynamic properties of the airfoil during its use.
    [0003] It is known from the prior art of the load-bearing wings for which the fin is fixed on the fuselage by screwing, which entails the following constraints: the fin must be positioned on or under the fuselage; - The fin must have one or more holes for the free passage of the threaded portion of the screws; - the fuselage must have one or more holes with a thread adapted to the screws; and - the screws of the fin must be through, which requires the use of screw heads. An additional disadvantage, related to such fasteners by screwing, is that the fin and the fuselage being superimposed, their respective sections add together and the hydrodynamic properties of the assembly are poor. In addition, the heads of the fastening screws, even if they are flush with the surface of the wing, never perfectly recover its profile, and are never smooth (impression of the screwing tool). In navigation, these surface defects are often greater than the boundary layer of fluid flow, and create disturbances in the flow of the fluid, which further reduces the hydrodynamic properties of the airfoil. Description of the Invention The object of the present invention is to overcome these drawbacks and to provide a wing for a nautical vessel carrying wing, which wing comprises a body and a means of fixing the fuselage of the airfoil, remarkable in that the fuselage fastening means of the fin has an attachment appendix extending from the body of the fin and provided to cooperate by interlocking in a complementary notch, provided for this purpose, in the fuselage.
    [0004] The complementary term, with respect to the notch, in connection with the appendix-notch assembly, does not exclude the presence of residual voids at the appendix-notch interface, even when the appendix and the notch are closely associated.
    [0005] This method of attachment allows a quick and easy assembly and disassembly of the fins, as well as a solid and precise fixing, while optimizing the hydrodynamic qualities of the fin-fuselage assembly of the airfoil. The risk of losing parts is limited, and the footprint is minimized which allows the use of a shorter fuselage for the same fin spacing.
    [0006] Advantageously, the appendage of the fin according to the invention is able to ensure a frictional hold in the complementary notch of the fuselage. The structure and the material of the appendix are likely to allow a pinching and a maintenance by friction which ensures a firm hold by the only establishment and slight support of the appendix in its notch.
    [0007] Advantageously, the attachment appendix comprises an edge protruding from its surface and adapted to block the rotational movements of said appendage in the complementary notch of the fuselage. Undesirable pivoting of the fin on the fuselage is thus avoided and the desired configuration is kept in navigation.
    [0008] Advantageously, the appendix comprises a first housing designed to receive a locking means. By way of non-limiting example, the locking means is a grub screw which passes through the housing and cooperates with a recess of the fuselage in contact with the appendage. Advantageously, the housing of the appendix is a through hole of circular section comprising a section comprising a tapping. Thus the insertion of a grub screw in said through hole can easily block the movement by abutting in a recess of the fuselage provided for this purpose. The appendix comprises, advantageously, a substantially rectangular section adapted to cooperate with the complementary notch, thus conferring on it an increased resistance to mechanical stresses. Advantageously, the appendix comprises a substantially frustoconical section adapted to cooperate with the complementary notch. Thus, the assembly and disassembly of the fin on the rest of the wing are facilitated. In addition, the frustoconical shape facilitates the manufacture of the fin by an economical method of injection molding. Advantageously, the appendage comprises a substantially trapezoidal section adapted to cooperate with the complementary notch. In this case, too, the release of the fin is facilitated when using an injection molding process to manufacture it. Advantageously, the appendage comprises a bulge on its surface, intended to be placed substantially in contact with the mouth of the complementary notch. Such a shape allows a rotation of the appendix about an axis perpendicular to its axis when it is placed in the notch, and this by a few degrees, while keeping in touch with the walls of the notch . It is therefore easy to adjust the angle of incidence of the fin. Advantageously, the appendix is substantially frustoconical and comprises on its surface a bulge of annular shape provided to cooperate with the mouth of the complementary notch. In this way, a displacement of the appendix in the notch can be done in all directions substantially perpendicular to the axis of the appendix. Advantageously, the appendix comprises a second housing, designed to receive a locking means, and positioned upside down relative to the first housing. As a result, when the ends of the two screws are in contact with the walls of the notch, all degrees of freedom of the appendage with respect to the notch are blocked. The desired angle of incidence can be finely adjusted by screwing or unscrewing at least one of the two screws. The present invention also relates to an inverted T-shaped airfoil capable of being fixed on one of the surfaces of a watercraft intended to be positioned on the water, comprising: a mast and a fuselage configured in a T-shape ; a notch formed on an end portion of the fuselage; and a fin as described previously in the context of the present invention, fixed on the fuselage by insertion of the fixation appendix into the notch. Advantageously, the airfoil according to the invention comprises: a fin containing a through hole of circular section, said through hole comprising a section comprising a tapping, as seen previously in the context of the invention; a notch of the fuselage having a first orifice and a first blind hole, such that both the center of the orifice, the axis of the through hole of the fin, and the axis of the blind hole, are substantially aligned in the configuration for which the appendix is inserted into its notch; and a fixing screw, which screw comprises a stud and whose threaded portion is adapted, firstly, to abut on the tapping of the through-hole by sliding, and, secondly, at the end of the race to come insert the screw stud into the blind hole by screwing. In this way, in the configuration for which the screw is fully screwed, the appendix is securely retained in the notch, and unwanted unwanted movement between the appendix and the notch is avoided.
    [0009] Advantageously, the notch comprises a second orifice and a second blind hole, such that the assembly formed by the second orifice with the second blind hole is positioned head to tail relative to the assembly constituted by the first orifice with the first hole. blind. Advantageously, the mast of the airfoil comprises a fixing heel to the watercraft. It is preferred to use heels known as the "TUTTLE heel", well known to those skilled in the art of water sports windsurfing and kitesurfing. The housings compatible with the TUTTLE heel are easy to use and adapt to any type of board. Other heels are also possible, such as the standards designated by the names: DEEP TUTTLE, POWER BOX or TRIM BOX.

    [0010] DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIG. 1 shows a general view of an inverted T-shaped airfoil 1. The carrying wing comprises a "t-bar" which is composed of a mast 2, oriented mainly along an axis offset by 10 ° relative to the "z" axis, and a fuselage 3, which extends mainly along the "x" axis. At the front of the fuselage 3 is placed a first fin 4a, or carrier plane, whose span extends substantially parallel to the axis "y". At the rear of the fuselage 3 is placed a second fin 4b, called stabilizer or plane spoiler, whose span also extends parallel to the axis "y". The load-bearing wing 1 is fixed to the boat or board by the attachment heel 5, which is here to be a standard of windsurfing called "TUTTLE heel", for its insertion in a compatible housing of the boat or board. The fin 4a is composed of a body 6 from which extends an appendix 7, as shown in Figure 3. The fuselage 3 has a notch 8 of complementary shape to the appendix 7. Figure 2 shows the fin 4a assembled in a part of the fuselage 3. This figure 2 is partially shown in section, in the plane Oxz (see the hatched areas), to show the junction between the appendix 7 of the fin and the notch 8 of the fuselage . In Figure 2, the perfect continuity between the profile of the fin 4a and the fuselage 3 made possible by this method of assembly is visible. The presence of a residual space 9 remains at the end of travel after insertion of the appendix into its notch. FIG. 3 shows the same embodiment, but this time, the appendix 7 is shown completely disassembled from the notch 8. In FIG. 2, also, the fin is shown in perspective seen from the side with its appendix of substantially rectangular section, or trapezoidal.
    [0011] FIG. 4 shows in a sectional view along the transverse plane and the direction AA, a section of an embodiment according to the invention described in FIG. 3 and for which the connecting appendix has a section of substantially rectangular. Figure 5 shows a portion of the fin 4a in section, with its appendix 7 in which is drilled a through hole 10, of circular section, threaded. A screw 11 is screwed into the through hole 10. It is screwed by the end of larger outer diameter which has a maneuvering footprint, for example a hexagon socket for the insertion of a so-called AIIenTM key. The other end of the screw 11 of smaller outer diameter comprises a pin 13 which is intended to open out of the hole as shown in Figure 6. The pin 13 is a cylinder having a chamfer on its most distal portion. FIG. 7 shows a part of the fuselage 3 seen in section at the notch 8. The notch 8 comprises an orifice 14 for the insertion of the screw 11, when it is screwed into the appendix 7, when this it is assembled in the notch. A blind hole 15 is also formed opposite the orifice 14, along an axis perpendicular to the insertion direction of the appendix in the notch. The blind hole 15 is made substantially complementary to the pin 13 of the screw 11 to block the displacements of the appendix in the notch when the screw 11 abuts on the blind hole 15, as shown in FIG. Figure 9 shows a variant for which the screw 11 is inserted in a direction oblique to the insertion direction of the appendix in the notch. Figure 10 shows a variant for which the pin 13 of the screw 11 is cone-shaped.
    [0012] In Figures 11 to 13 different appendages are shown inserted into their complementary notches. The appendix may have a longitudinal section: rectangular in shape, as shown in Figure 12; frustoconical shape, as seen in Figure 13; consisting of an alternation of rectangular portions 28a, 28b and conical 29. Figure 14 shows a detailed part of another embodiment of the wing-fuselage assembly. For this embodiment, on a fin body 36 extends an appendix 37 on the surface of which two bulges 38a and 38b are disposed on its proximal portion. Once put in place in a notch 39 complementary to the fuselage, a rotation of a few degrees of the appendix about an axis perpendicular to the plane of section is possible, thanks to a game left in an internal space 40 present between the appendix and his notch. Appendix 37 is traversed by two threaded holes 41 and 42, identical to the through hole 10, shown in Figure 5, arranged in parallel, as seen in Figure 15. In the notch 39, a first and a second hole blind 43 and 44 are drilled, they are identical to the blind hole 15, shown in Figure 7. In the notch 39, a first and a second port 45 and 46 are drilled, they are identical to the orifice 14, shown in FIG. In this embodiment, screws 47 and 48 screwed into the threaded holes 41 and 42 to abut the blind holes 43 and 44 occupy a so-called head-to-tail arrangement with respect to the another, as shown in Fig. 14. For the embodiment of Fig. 14, when the screws 47 and 48 abut in the threaded holes 41 and 42, the rotation of the appendix 37 in the notch 39 is locked in a position chosen by the user, and the angle of incidence of the wing e is locked. Changing the angle of incidence is done by unscrewing one screw and screwing the other. A space 50 is left at the base of the appendix to allow the free rotation of the fin along an axis substantially parallel to the axis "Oy" without it translate on the axis "Ox". The adjustment between the pins 51 and 52 of the screws 47 and 48, and the blind holes 43 and 44, is sufficiently loose to allow a slight offset between the axis of the screws 47 and 48 and the axis of their respective blind holes 43 and 44, that entails the modification of the angle of incidence.
    [0013] FIG. 15 represents, in section along the "Oxz" plane, a detail of another embodiment at the level of the appendix arrangement 57 in its notch 58, the appendix comprising bulges 59a and 59b on which ridges bright are protruding. The inventor also proposes an evolution of the TUTTLE heel / housing pair, compared to a conventional TUTTLE, more in line with the constraints of the airfoil. This heel has a boss of a constant height of 56 mm, starting from a rectangle base of 156 mm long by 16 mm wide, like the TUTTLE box. The front and rear faces of the heel are inclined by 10 ° inwards and the lateral faces are each inclined by 0.5 °. On the heel, the edges of the boss are rounded with a radius of 4.5 mm. In the case, the corresponding edges are rounded by a radius of 4 mm, so that the faces, and not the angles of the housing and the heel, are in contact. Fixing is done with screws, through the top of the heel, via threaded holes, axes spaced 10.5 cm and placed symmetrically on the heel.
