Description

Title of the invention: Multi-purpose fastener, fastening system and vehicle comprising such a system. Technical field

[0001] The invention relates to a multi-purpose fastener and a fastening system comprising the multi-purpose fastener, but also a vehicle comprising said fastening system. Prior art

[0002] Many fastening methods are known for transporting goods, particularly on a vehicle. Unfortunately, their use is often specific and may, for example, be limited to the dimensions of roof bars or roof storage boxes. Generally, the fastenings used are not adjustable or are simply immovable once installed and do not allow for tamper-proof securing of the accessories.

[0003] The invention aims to overcome all of these drawbacks. Description of the invention

[0004] The invention aims to provide a technical solution for attaching accessories to a support, particularly for vehicles, which can be reliable, removable and lockable.

[0005] In this context, the present invention relates to a multi-purpose fastener comprising: - a fixing piece comprising a plate and a skirt, the plate being disposed on one side of the skirt and its dimensions being greater than the dimensions of a cross-section of the skirt which is elastically deformable, the fixing piece having a housing which extends at least partially into the skirt, in particular, the housing being transverse to the fixing piece, - a locking pin that is configured to fit into the housing of the fastener, the locking pin being movable between, on the one hand, an unlocked state in which the locking pin is fitted into the fastener but does not apply any stress to the skirt, and on the other hand, a locked state in which the locking pin applies stress to the skirt, which deforms and produces a clamp formed between the deformed skirt and the plate, the clamp being capable of gripping a plate, and - means of actuating the locking pin so as to move the locking pin from the unlocked state to the unlocked state and vice versa.

[0006] The locking pin allows the fastening piece to be elastically deformed to produce a clamp or flange capable of gripping a plate. The multi-purpose fastener thus allows, through mechanical deformation, the clamping of a flat support such as a plate, while this mechanical deformation is stabilized by the shape of the locking pin and the fastening piece, as well as by the locking means.

[0007] The fastener includes elastic deformation properties which allow the part to be deformed under stress and to maintain a stable mechanical deformation such as lobbes and can return to the initial shape as soon as more stress is applied to the fastener.

[0008] Furthermore, the actuation means allow, on the one hand, the locking pin to be actuated to move it from the unlocked state to the locked state and vice versa, and on the other hand, the multi-purpose attachment to be secured in its locked state. [Lock / Unlock]

[0009] In some embodiments, the locking pin may have a head configured to be accessible and protrude at least to the level of the mounting plate. The actuation means include a locking recess formed in the head and a locking key comprising a male member complementary to the locking recess. The locking key allows the locking pin to be moved from the unlocked state to the locked state and vice versa. Preferably, the locking key is removable from the locking recess. In particular, the male member may be a cam. The recess secures the multi-purpose fastener in the locked state because it may be specific to the cam of a locking key. For example, a specific recess may be fitted to a batch of multi-purpose fasteners that are marketed with a corresponding locking key.

[0010] In some embodiments, the imprint can be fixed relative to the head of the stud so that the locking key causes the stud to rotate relative to the fastening piece. This simplifies the mechanical design of the multi-purpose fastener.

[0011] In embodiments, the locking block can be mounted to rotate freely through a determined angular deflection, preferably the value of the angular deflection is between 45 and 90°. [Constraint]

[0012] In embodiments, the locking pin may comprise a rigid compression body having a serrated cross-section with projections and recesses, the housing comprising an internal cross-section complementary to the compression body, the housing also includes protrusions and hollows.

[0013] In some embodiments, in the unlocked state, the projections of the compression body can be inserted into the recesses of the housing, while the recesses of the compression body are fitted into the projections of the housing. In the locked state, the projections of the locking pin are placed against the projections of the housing, which are then compressed, producing an elastic deformation of the skirt. Thus, when the locking pin rotates, the projections of the compression body apply a stress to the projections of the housing, resulting in a lateral or radial elastic deformation of the skirt of the fastener.

[0014] In some embodiments, the projections of the locking pin each have a groove configured to stabilize the compression of the housing projections when the locking pin is in the locked state. The groove thus helps to secure the multi-purpose fastener in the locked state of the pin. In other embodiments, the housing projections may also have a groove that complements the grooves formed on the projections of the compression body. The grooves on the housing projections benefit from the elastic deformation properties of the fastener and deform under the stress of the projections in order to stabilize the locking pin in its locked state.

[0015] In some embodiments, the locking pin may include a plate that abuts the skirt when the locking pin is inserted into the fixing piece. In particular, in the locked state, the plate prevents the elastic deformation of the skirt. Furthermore, the plate also secures access to the housing, thereby limiting malicious acts aimed at unlocking the locking pin with a blunt object. [Fixing part]

[0016] In some embodiments, the fastening piece may include recesses interposed between the skirt and the platform; the recesses are laterally interposed with spacers that ensure the mechanical connection between the platform and the skirt. The recesses improve the deformability properties of the skirt.

[0017] In embodiments, the recesses can guide the elastic deformation of the skirt under the stress of the projections of said locking block, the elastic deformation producing lobes allowing a plate to be gripped with the plate.

[0018] In embodiments, the multi-purpose fastener may comprise one or more fasteners arranged on the plate of the fastening piece. In particular, a fastener may include a loop projecting from the plate. The fastener thus allows straps and other cables, or elastic bands, to be passed through it to attach accessories to a support. According to a preferred embodiment, the loop can be rigid. This provides a rigid anchor.

[0019] In some embodiments, the fastener comprises a reinforcement at least partially embedded within the body of the fastener. In particular, the reinforcement may be partially embedded in the skirt of the fastener. In one embodiment, the reinforcement may consist of a wire rope formed in a serrated manner. In another embodiment, the reinforcement may be arranged coiled within the fastener. The reinforcement may be coiled around the central longitudinal axis of the fastener; for example, the reinforcement may comprise two superimposed coaxial revolutions within the skirt. The reinforcement improves the mechanical strength of the fastener and helps to stabilize the fastener when the locking pin is in the locked position. The reinforcement also improves the resistance of the multi-purpose fastener to tampering.

[0020] In some embodiments, the reinforcement may include at least one loop projecting from the plate of the fastener, the loop thus forming the protruding attachment of the plate. According to this embodiment, loops forming attachments may alternate with junction sections embedded in the fastener and form a serration. This configuration reduces manufacturing costs by using the reinforcement to form the attachments and improves the mechanical strength of the attachments.

[0021] In some embodiments, the housing may extend through the fastener along a longitudinal axis of the fastener. In one embodiment, the housing may have an opening formed in the plate, said opening extending through the plate in an inverted conical manner. This particular shape of the opening forms a keying feature that improves the fit between the fastener and the locking pin, the head of which is shaped in a complementary way to improve the fit between the two parts in a specific direction.

[0022] In some embodiments, the housing may include a second opening opposite the first, formed in the skirt. The second opening may have larger dimensions than the first opening. According to this configuration, the second opening allows the locking pin to be inserted into the fastener. Note that, according to a particular embodiment, the locking pin may include a plate at the opposite end from the pin head. The plate thus forms a base that is configured to secure access to the housing. [Multi-purpose fastening system]

[0023] The invention also relates to a multi-purpose fastening system comprising: - one or more conforming multi-purpose fasteners of the invention, and - a support perforated with a predetermined number of holes, the dimensions of the holes being complementary to the dimensions of the fastening piece of the multi-purpose fastener in order to allow the insertion of the fixing piece into the hole, the skirt of the fixing piece allows to form a clamp with the plate of the same multi-purpose fastener and thus to clamp the support around the hole into which said multi-purpose fastener is inserted.

[0024] The fastening system can be used in several fields to secure accessories or objects to a support. The support is preferably flat and of constant cross-section in the vicinity of an opening, but can take several forms. [Land vehicle]

[0025] The invention also relates to a land vehicle, in particular an all-terrain vehicle, the vehicle comprising at least one multi-purpose fastening system defined according to the invention, the support being fixed directly or indirectly to the body of the vehicle, in particular, the support can be arranged inside or outside the passenger compartment of the passenger compartment of the vehicle.

[0026] Of course, the land vehicle can be of all types, for example, a 4x4 or other motor vehicles. Brief description of the drawings

[0039] With reference to figures 1 to 11, the invention relates to a multi-purpose fastener 20 which includes a fixing piece 21 and a locking stud 22. According to an embodiment of the invention illustrated in figures 9 to 11, the locking stud 22 is movable between an unlocked state and a locked state in which the fixing piece 21 has an elastic deformation which allows a stress to be applied to a support 23 and the fastener 20 to be secured to the latter by clamping.

[0040] According to an embodiment illustrated in particular in figures 5 and 6, the fixing piece 21 is configured to be inserted into an orifice 230 provided in a support 23. The support 23 is here a plate which has a defined and constant thickness at least in the vicinity of each orifice 230.

[0041] In particular, as illustrated in Figures 1 to 3, the fastening piece 23 includes a plate 210 that is configured to project from the support 23. In one embodiment, the plate 210 has a disc shape. In particular, when the fastener 20 is inserted into an opening 230 in a support 23, the plate 210 extends beyond the periphery of the opening 230 so as to constitute a support or edge for clamping the support 23.

[0042] According to an embodiment illustrated in particular in Figures 1 to 3, the plate 210 may include at least one fastener 211. As illustrated in Figures 1 to 11, the plate 210 may include several fasteners 211. In particular, the plate 210 may include four fasteners 211, as illustrated in particular in [Fig. 3]. However, it is possible to provide a plate 210 comprising more than four fasteners 211. In this example, each fastener 211 has a loop that protrudes from the mounting plate 210.

[0043] According to a particular embodiment, each fastener 211 is a projecting loop of the plate which is integral with a frame 213 which is embedded in the body of the fastener 21. According to the embodiment illustrated in [Fig. 3], the frame 213 comprises loops 2130 partially projecting from the fastener plate 210 which are connected between them by a connecting section 2131 embedded in the body of the fixing piece. The alternation of loops 2130 and connecting section 2131 forms a crenellation.

[0044] In the example of [Fig. 3], the reinforcement 213 can be made of a wire rope shaped in a crenellated manner to form the loops 2130 and the connecting sections 2131. In one embodiment, the reinforcement 213 is also arranged coiled within the fastening piece 21, as shown in [Fig. 3], in which an opening 2132 between two ends of the reinforcement 213 is visible through the body of the fastening piece 213. The wire rope can, for example, be a steel wire. According to the embodiment of [Fig. 3], the reinforcement 213 comprises two coaxial revolutions and extends into the walls of the skirt 214. Furthermore, the four loops 2130 are arranged parallel to each other in pairs. The fixing piece 21 can be manufactured by pouring a material in a non-cohesive state into a mold in which the reinforcement is pre-positioned.

[0045] As can be seen in particular in figures 6 and 12, the plate 210 is configured to protrude from the support 23 so that the attachment 211 is accessible by a user or a strap.

[0046] To this end, the fastening piece 21 includes a skirt 214 which is elastically deformable. For this purpose, the fastening piece 21 may comprise one or more elastomeric materials such as polyurethane, EPDM (ethylene-propylene-diene monomer), SBS (poly(styrene-butadiene-styrene)), nylon, etc.

[0047] According to the embodiment of [Fig. 4], the skirt 214 is integral with the plate 210, which is disposed at one end of the skirt 214. In this example, the skirt 214 is cylindrical, and the periphery of the plate 210 extends beyond the walls of the skirt 214, forming a shoulder. According to an embodiment illustrated in particular in Figures 1, 3, and 4, the skirt 214 is a cylinder with a circular base. However, the base of the skirt cylinder 214 can take other forms, provided that the shape and dimensions of the skirt 214 are designed to complement the openings 230 of the support 23. This is so that the skirt 214 can be inserted into an opening 230 of the support 23 as illustrated in Figures 5 and 6. After insertion into the opening 230, the skirt 214 is positioned behind the support 23 as illustrated in Figures 9 and 10.

[0048] Furthermore, the fastening piece 21 has a housing 215 configured to receive the locking pin 22 by interlocking. According to an embodiment illustrated in particular in Figures 2 to 4, the housing 215 passes longitudinally through the fastening piece 21. The housing 215 thus has a first opening 216 formed in the plate 210. In particular, the first opening 216 has the shape of an inverted truncated cone; this particular shape improves the interlocking with the locking pin, which has an interlocking head 220 of the shape complementary. According to an embodiment illustrated in figures 1 and 2, the insertion head 220 can be of inverted conical and truncated shape.

[0049] As illustrated in particular in the embodiment of [Fig. 4], the housing 215 includes a second opening 217 which is coaxial with the first opening 216. The second opening 217 is located opposite the first opening 216, which is formed in the skirt 214. As can be seen in this [Fig. 4], the housing 215 includes a cavity which has a specific shape. The cavity of the housing 215 extends into the elastically deformable skirt 214. In particular, the housing 215 includes an internal cross-section having projections 2150 and recesses 2151. The projections 2150 and the recesses 2151 extend into the cavity of the housing 215 longitudinally and parallel to the longitudinal axis of the fastener 21. As illustrated in Figures 4 and 12, the projections 2150 and the recesses 2151 are arranged alternately such that a projection 2150 is adjacent to two recesses 2151, and similarly, a recess 2151 is adjacent to two projections 2150.According to a particular embodiment illustrated in particular in [Fig.4], each projection 2150 includes a groove 2152 which also extends longitudinally in the projection 2150. In particular, the groove 2152 extends on the longitudinal median axis of the projection 2150.

[0050] According to another embodiment illustrated in particular in Figures 1 to 4 and 11, the fastening piece 21 may include recesses 218 interposed between the skirt 214 and the plate 210. The recesses 218 are interposed with spacers 219 which provide the mechanical connection between the plate 210 and the skirt 214. In the example of Figures 3 and 4, each recess 218 extends radially over a portion of the circumference of the skirt 214. The recesses 218 communicate with the cavity of the housing 215. This is clearly visible in the cross-sectional view of [Fig. 2].

[0051] According to the embodiment of [Fig. 1], the locking lug 22 comprises a rigid compression body 221. The compression body 221 is, in fact, made of a material whose elastic deformation properties are less significant than the elastic deformation properties of the fastening piece 21. The compression body 221 is configured such that the stress applied to the skirt 214 by the compression body 221 results in an elastic deformation of the skirt 214. In this respect, the locking lug 22 may comprise polyoxymethylline, also known by the acronym POM.

[0052] According to an embodiment shown in Figures 1 and 12, the compression body 221 comprises a serrated cross-section having projections 2210 and recesses 2211. The projections 2210 and recesses 2211 are arranged alternately on the compression body 221 in the same way as the projections 2150 and recesses 2151 of the housing 215. The cross-section of the compression body 221 is complementary to the internal cross-section of the skirt 214 so that the stud The locking pin 22 can be inserted into the housing 215, the compression body 221 fitting into the housing 215, and the upper face of the head 220 of the locking pin 22 emerging at the level of the plate 210. For this purpose, the projections 2210 of the compression body 221 are configured to be inserted into the recesses 2151 of the housing 215. Similarly, the projections 2150 of the housing 215 are configured to be inserted into the recesses 2211 of the compression body 221. Thus, the dimensions of the recesses 2151, 2211 and projections 2150, 2210 are defined to allow a precise fit between the locking pin 22 and the fixing piece 21.

[0053] Moreover, as can be seen in figures 1 and 12, the projections 2210 of the locking stud 22 respectively have a groove 2212. Here, the groove 2212 extends along the longitudinal median axis of the projection 2210.

[0054] According to the embodiment shown in Figures 1 and 9 to 11, the locking pin 22 comprises a plate 222. Here, the plate 222 is positioned opposite the head 220 and integral with the compression body 221. The diameter of the plate 222 is greater than the dimensions of the cross-section of the compression body 221, such that the periphery of the plate 222 extends beyond the projections 2210 of the compression body 221. When the locking pin 22 and the fixing piece 21 are assembled, the plate 222 abuts the skirt 214 of the fixing piece 21 as illustrated in Figures 9 to 11.

[0055] Since the compression body 221 is configured to fit into the housing 215, when the locking pin 22 is inserted into the fastener 21, the locking pin 22 is in an unlocked state. In this state, the locking pin 22 is fitted into the fastener but does not apply any stress to the skirt 214 of the fastener 21. When the locking pin 22 changes from the unlocked state to the locked state, the locking pin 22, and in particular the compression body 221, applies a stress to the skirt 214, which deforms as illustrated in Figures 10 to 12.

[0056] As illustrated in [Fig. 10], when the multi-purpose fastener 20 is inserted into an opening 230 in a support 23, the deformations of the skirt 214 press the support 23 against the plate 210. Advantageously, the recesses 218 improve the deformation capacity of the skirt 214 under the stress of the compression body 221. Furthermore, the recesses 218 also help to guide the elastic deformation of the skirt 214 under the stress of the projections 2210 of the compression body 221. As can be seen in [Fig. 10], the elastic deformation of the skirt 214 produces lobes 2140 in the vicinity of the recesses 218 (see [Fig. 11]), and the support 23 is then clamped between the lobes 2140 and the plate 210.

[0057] According to an embodiment illustrated in Figures 9 to 12, the locking pin 22 is mounted to rotate freely through a travel The angular displacement is of a determined value. In particular, the angular displacement is between 45° and 90°. The consequence of the rotational displacement of the locking pin 22 is that the skirt 214 deforms laterally or radially, as illustrated in [Fig. 10] by arrows extending outwards from the skirt 214. The rotational mobility between the unlocked and locked states, and vice versa, is illustrated in Figures 9 and 11 by arrows shown, in particular, at the level of the plate 222.

[0058] This lateral / radial deformation is due to the fact that the rotation of the locking pin 22 causes the displacement of the projections 2210 of the compression body 221 from the hollows 2151 of the housing 215, in which said projections 2210 are housed in the unlocked state, towards the projections 2151 of the housing 215 which are then subjected to a lateral or radial stress which pushes back the projections 2151 and produces an elastic deformation of the skirt 214 in the locked state of the pin 22.

[0059] The cooperation between the stud 22 and the fixing piece 21 in the locked state is illustrated in [Fig.12], on which the projections 2210 are arranged against the projections 2150 and cause the deformation of the skirt 214. This figure also shows that the grooves 2152, 2112 fit into each other and thus help to guide and stabilize the deformation of the skirt 214 in the locked state.

[0060] As illustrated in Figures 7 to 11, the multi-purpose fastener 20 includes actuating means 24 for the locking pin 22, such as to move the locking pin 22 from the unlocked state to the unlocked state and vice versa. In particular, the actuating means 24 rotate the pin 22 through a predetermined angular displacement to transition between the locked and unlocked states.

[0061] As can be seen in Figures 7, 13, and 14, in one embodiment, the head 220 of the locking pin 22 protrudes at least to the level of the plate 210 of the mounting piece 21 so as to be accessible to a user. In another embodiment illustrated in particular in Figures 7 and 8, the actuation means 24 comprise a locking recess 240 formed on the head 220 and a locking key 241. The key 241 comprises a male member 242, such as a bit, which is complementary to the locking recess 240. The recess 240 is fixedly formed in the head 220 of the pin 22 so that the rotation of the key 241 causes the pin 22 to rotate relative to the mounting piece 21.

[0062] As illustrated in figures 9 to 11, the locking key 241 allows the locking pin 22 to be moved from the unlocked state to the locked state and vice versa; preferably, the locking key 241 is removable from the locking imprint 240.

[0063] As illustrated in Figures 7 to 10 or 13 and 14, the invention also relates to a multi-purpose fastening system comprising, on the one hand, one or more Multi-purpose fasteners 20 conforming to the invention, and on the other hand, a support 23 perforated with a predetermined number of holes 230. In particular, the dimensions of the holes 230 are defined as complementary to the dimensions of the fastening piece 21 of the multi-purpose fastener 20. According to one embodiment, the support 23 comprises a predetermined number of holes 230 which are distributed symmetrically over all or part of the support 23. The holes may also be spaced from each other by a predetermined constant or different distance depending on the configuration of the support 23.

[0064] Preferably, the height of the recess 218 is at least equal to the thickness of the plate which forms the support 23.

[0065] According to the embodiment of [Fig. 13], the plate 210 of the multi-purpose fastener 20 includes four fasteners 211 which allow, for example, straps 25 to be passed through to attach objects to the support 23. In this embodiment, the holes 230 of the support 23 are spaced from each other by a determined distance and distributed symmetrically on the support 23.

[0066] According to the embodiment of [Fig. 14], the multi-purpose fastener 20 comprises a plate 210 without an additional fastener and allows a lamp 26 to be attached through a profile 260 on which the lamp 26 is mounted. The profile 260 has holes that are substantially the same size as the openings 230 in the support 23. The fastener 21 is then inserted into the hole in the profile 260 and into the opening 230 in the support, the hole and the opening 230 being positioned coaxially. Locking the pin 22 then allows the profile 260 and the support 23 to be clamped between the plate 210 and the skirt 214, with the two sides pressed together.

[0067] According to an embodiment illustrated in Figures 15 and 16, the multi-purpose attachment 20 can be used to attach equipment or objects to a vehicle 27. In the example of [Fig. 15], the vehicle 27 is an all-terrain land vehicle. For this purpose, a support 270 can be integrated into the vehicle inside the passenger compartment, for example, in the trunk, or even outside the passenger compartment. The support 270 can thus be fixed to the body or replace a part of the bodywork in certain places. The vehicle 27 can therefore include a support 270 on the grille, the front hood, the rear hood, the sides of the vehicle, the doors, the roof, etc.

[0068] In the example of [Fig. 15], the support 270 is located in the side of the bodywork near the access opening to the passenger compartment of the vehicle 27.

[0069] In the example of [Fig. 16] a fire extinguisher 271 is held against the bodywork by means of straps 272 which are secured to the support 270 by multi-purpose fasteners 20.
