Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to the field of equipment for the practice of sliding sports, especially on snow. It is particularly directed to the interface between the user's foot and a gliding board. It proposes for this purpose a reception device of a foot or a shoe on a gliding machine.

Such sets are, for example, intended for snowboarding or snowboarding.

STATE OF THE ART

Known solutions propose reception devices able to receive, each, a shoe of the user. These reception devices comprise a seat portion intended to be fixed relative to the gliding board. This portion of the seat is adapted to receive the sole of the shoe. It is in particular by the seat that is applied to the gliding machine, at least in majority, the weight exerted by the user. The known reception devices also include means for maintaining the shoe. On the one hand, they comprise parts providing lateral support of the shoe and, on the other hand, at least one attachment of said shoe to the seat, for example, by links. The assembly thus offers a home for the boot that is able to hold it sufficiently in position relative to the gliding machine and to authorize a transmission of forces applied by the user for the control of the machine, for example when 'a catch of edges.

Lateral support is important in this context, and known techniques implement a hoop able to partially surround the base of the shoe beyond the seat. The arch may have a concave shape, partially surrounding the heel of the foot or the shoe. The arch extends from a lateral edge of the seat, towards the other lateral edge, by traversing the rear part of the reception device so as to offer a cohesion element with the foot, generally at least by the back of the foot joint.

For effective transmission of the efforts of the user to the machine, we are currently looking for a strong rigidity between seat and hoop. Also, with the current designs, the hoop is not intended to deform. This rigidity provides a good support of the shoe but can be inconvenient for the user to use, especially during lateral or forward movements. In addition, being rigid, the hoop creates areas of hard contact with the shoe and more particularly when tilting the shoe around a longitudinal axis to the attachment, which can be a source of discomfort. On the other hand, this design limits foot movement relative to the board. However, for some practices, especially for performing acrobatic tricks, the surfer wants more freedom of movement to get more ease and control of his jumps.

Moreover, this design induces high stresses on the structure of the binding. For example, the fasteners circling the shoe by the top of the instep are exposed at high stresses. The hoop is also strongly stressed, particularly in flexion, during the forward movements of the surfer.

Some fasteners provide lateral damping of the arch but with very limited symmetrical deflections. The arch still retains too much rigidity. The documents AT409933B and US-2004/0119265 provide flexibility to the hoop by mounting it on pivots and an elastic system of recovery forces. The object of the invention is to provide an improved reception device.

One goal is to provide a home device offering more freedom of movement for the foot or the shoe compared to the seat.

Another goal is to offer a comfortable home device.

Another object of the invention is to provide a robust home device.

SUMMARY OF THE INVENTION

The invention proposes a device for receiving a foot or a shoe on a gliding apparatus comprising: a seat which extends in a longitudinal direction from a rear end to a front end, and in width, from a first edge to a second edge, and a hoop extending towards the rear end of the seat, the hoop being connected to the seat by a connecting system comprising first and second points of grip, these attachment points providing rigidity ensuring maintenance and mechanical consistency between the seat and the arch so that the hoop is self-supporting. The docking device is characterized in that the connecting system comprises at least one connecting element connecting a rear lateral portion of the bow to the seat so as to limit a relative movement of spacing between the rear lateral portion. of the arch and the seat, while allowing the relative movement of approach between the rear side of the arch and the seat.

Thanks to the invention, a movement is authorized between the seat and the rear part of the arch so that these parts can accommodate variations of solicitations of the foot or the shoe. At the same time, this capacity is limited so as not to penalize the maintenance and preserve the structure of the reception device.

The limitation of the relative distance movement between the rear lateral part of the arch and the seat makes it possible to reduce the stresses exerted on the arch and more particularly at the points of attachment. Indeed, this zone can be strongly constrained in flexion which can cause the rupture of the connection of the arch with the seat.

There is a better application of the foot or the shoe on the seat during movements, especially forward. In addition, the connection between the hoop and the seat is less rigid, at least in a limited operating phase clearance, so that it is less constrained and it is thus preserved the risk of rupture.

In terms of driving, the connecting elements provide flexibility in the behavior by allowing an energy twist or not the foot around an axis longitudinal of the device. The realization of figures of style is then facilitated.

Moreover, while the lateral supports of the shoe on the rollbar are currently uncomfortable, stumbling on the rollbar, they are improved with fewer hard points in the contact with the arch which resumes more generally and with a certain flexibility these efforts. During these lateral stresses, the support of the sole on the seat is preserved.

DETAILED DESCRIPTION OF THE INVENTION

Before going into details of the embodiments of the invention, in particular with reference to the various figures, certain details are given below.

In general, the longitudinal direction of the reception device means the direction corresponding to the length of the foot or the shoe of the user and directed in the direction marked "x". When the docking device is mounted on a gliding machine, this direction "x" is generally directed obliquely relative to the longitudinal direction of the gliding machine, including a surfboard. Unless otherwise stated, width means a direction directed perpendicular to the longitudinal direction and corresponding to a width dimension of the foot or the shoe of the user. This direction is illustrated at the "y" mark. Finally, the terms "height" or "vertical direction" denote a dimension directed according to the height of the user in the rest position and corresponds to the direction marked "z".

A first piece is, according to the present description, considered "integral" with another piece when these two pieces are linked for at least one degree of freedom, it being understood that the pieces may not be linked for other degrees of freedom. freedom. For example, a part may have freedom of movement in rotation along an axis relative to another part and be linked in translation in another direction. Similarly, a part is fixed in one direction when its mobility is prohibited relative to another part in said direction. This does not necessarily imply that the part is also fixed in other directions, in translation or in rotation. Thus, the term "fixed" in one direction does not necessarily imply a complete embedding of two pieces.

In general, the front part of the device is a part directed more towards the distal end of the shoe or the foot of the user, that is to say towards the toes. Conversely, the term "rear" refers to parts directed towards the rear end of the foot or shoe at the heel. The adjective "median" or "median" refers to an area in the middle of the dimension in the longitudinal direction of a room.

The figure 1 generally presents an embodiment of the reception device 1 of the invention to report on a gliding board 10. More specifically, the receiving device 1 comprises a seat 100, an upper face 101 is adapted to cooperate with the foot or the user's shoe via the sole. Opposite the upper face 101, a lower face 102 is intended to come into contact with an upper face 11 of the gliding board 10. More specifically, the seat 100 generally comprises a front end 103 and an end. back 104 for example spotted at figures 3 and 5 . These ends 103, 104 are joined, substantially in the longitudinal direction "x". The seat is delimited laterally by a first - 105 - and a second edge 106. Known relative fastening means between the gliding board 10 and the seat 100 are provided.

In addition to this support part by the bottom of the shoe, the reception device 1 comprises different elements of retention of the foot / shoe inside the device. In particular, a hoop 200 is formed so as to extend laterally relative to the seat 100 and to the rear part of the seat and therefore, the device. The arch is designed to surround the heel and lateral (lateral and medial) edges of the shoe.

At the first and second edges 106, the hoop 200 is joined to the seat 100 via a first and a second attachment point 108. In the illustrated example in the various figures, the first point of attachment 107 corresponds to the triangulated connection between a lateral portion 201 of the arch 200 and a lateral portion 105 of the seat 100.

In the embodiments given in the figures, the attachment points 107, 108 are formed at the front part of the seat 100, that is to say, in front of its median zone, towards the front end. 103. The first 107 and second attachment points 108 participate in a connection system between the seat 100 and the arch 200 providing rigidity ensuring the maintenance and mechanical consistency between these two parts. In this example, the seat 100 and the hoop 200 form a single monolithic piece, connected at the points of attachment 107, 108. Alternatively, the hoop can be a separate part of the seat. In this case, the arch is attached by being fixed on the seat by appropriate fastening means. According to one variant, the arch forms a closed loop shaped to follow the morphology of the shoe. Each arch comprises two lateral arms extending towards the rear of the device and connected by a curved part in its rear part.

The invention proposes a capacity for relative movements of the rear part of the arch 200 and the seat 100. The connection system is therefore configured to allow this relative deflection. In this example, the arch 200 extends rearwardly and is included in a plane inclined relative to the plane of the seat, at an angle of between 15 and 45 °. This inclination makes it possible to increase the length of the lateral portions 201 of the arch which facilitates their bending around an axis substantially connecting the points of attachment 107, 108. In other words, this bending deformation can be likened to a rotation around an axis directed according to the dimension "y" of the device and centered on the center of the first 107 and second attachment points 108. The movement results in a relative movement of spacing or approximation between the rear part of the arch and the seat. This relative movement is substantially vertical.

Of course, other forms of connection than those illustrated are within the scope of the present invention. Moreover, the first 107 and second attachment points 108 are not limiting and the connection system may comprise additional links or the points of attachment 107, 108 may be made in several parts.

Before going into the details of the cooperation between the arch 200 and the seat 100, it is indicated that the reception device 1 comprises, in the illustrated examples, links before 410 reported at the seat 100 through attachment zones 109 and allowing the establishment of a holding element of the front of the foot of the shoe, at the toes.

Similarly, rear links 420 are reported at the level of the seat allowing the establishment of an element of holding the instep of the shoe.

The links 410 and 420 are complementary to hold the user's shoe in position at two distinct zones along the longitudinal dimension of the reception device 1.

In the illustrated example, another element holding the shoe in position is constituted by a rear support element 300 extending along the height dimension of the receiving device 1 so as to extend the hoop 200 in this direction and serve as additional support element of the back of the boot on the docking device 1. The rear support element 300 has a substantially casing shape adapted to match the shape of the rear of the boot. the shoe. It is articulated relative to the arch 200 via a first - 301 - and a second articulation zones 302 diagrammatically shown in FIG. Figures 1 and 2 .

To limit the rearward pivoting of the rear support element 300 relative to the seat 100, the element 300 bears on the arch 200. According to the illustrated embodiment, the rear support element 300 is equipped with a stop 303 adapted to be applied on a portion of the arch 200 in a maximum position of pivot backwards.

In a non-illustrated embodiment, the rear support element 300 is pivotally mounted relative to the seat 100 and not with respect to the hoop 200.

As indicated above, the connection system placed between the seat 100 and the arch 200 allows a residual freedom of movement and in particular a relative movement allowing a bringing closer of the rear part of the arch 200 to the seat 100 is a spacing, of opposite direction in the same direction of movement, which due to the low angles used, corresponds to a displacement on an angular sector substantially comparable to a vertical translation between the rear part of the arch 200 and the rear part of the seat 100.

The relative movement of spacing or approximation is, according to the invention, limited in its race so, in particular, not to allow excessive spacing of the rear part of the arch 200 relative to the seat 100.

Thus, during the movements of the user, the latter benefits from a phase in which the arch 200 substantially follows these lateral movements or forward, and a phase during which the rear part of the arch 200 n is more able to be removed from the seat 100 so as to avoid too large spacing may penalize the holding of the shoe and to avoid too much stress on the points of attachment 107, 108 between the seat 100 and the arch 200.

To achieve a linkage system providing a limitation of the relative movement stroke between the seat 100 and the arch 200, the present invention implements connecting elements 500, two embodiments of which are illustrated in the figures.

The connection system thus comprises, at the level of at least one edge 105, 106, a connecting element 500 connecting a rear lateral portion 207, 208 of the arch to the seat so as to limit a relative movement of spacing between the rear lateral portion of the arch and the seat, while allowing the relative movement of approximation between the rear lateral part of the arch and the seat.

In the case of figure 1 to 4 , the connecting element 500 disposed on each side of the seat 100 is an isolated element. In the embodiment of Figures 5 to 7 , the connecting element 500 is coupled to a compressible element 600.

With reference to the first embodiment of the Figures 1 to 4 two connecting elements 500 are shown each situated on an edge 105, 106 different from the seat 100. More particularly, the connecting elements 500 may be situated in the rear part of the first and second edges 106 of the In this way, each connecting element 500 also cooperates with a rear lateral portion 207, 208 of the arch 200.

In general, the connecting element 500 is configured to allow, according to a limited range of movement, the displacement of the rear part of the arch 200 relative to the seat 100 by changing the configuration of the elements 500. configuration change means a deformation of the connecting element 500, a movement of the element 500 or any other change in shape or position of the element 500 to achieve a limitation of the deflection. The configuration change of the connecting element 500 allowing the movement is however limited so that only a relative mobility race between the arch 200 and the seat 100 is possible.

In the embodiment of Figures 1 to 4 , the element 500 is in the form of a tab, for example an elongate piece of a polymeric material and in particular polyurethane or polycarbonate, said tab being mounted firstly on the arch 200 and secondly on the seat 100. With the seat 100, as well as with the arch 200, the connecting elements are cooperating by areas where connections are made.

These connections are not synonymous with embedding according to the present invention in the sense that cinematic freedoms can be preserved, as indicated below. More specifically, in this example, a tab making a connecting element 500 is secured to a rear lateral portion 207, 208 of the arch 200 so as to link their displacement in the direction of the desired relative movement between the seat 100 and the seat. arch 200, namely the spacing or the approximation.

In the illustrated example, this fixing in position is carried out by means of a shaft 205 passing through a hole 504 located at a first end 501 of the connecting element 500 in the form of a tab and cooperating with a bearing made in FIG. 200. Thus, the displacement of the rear portion of the arch 200 causes the same displacement of the leg 500 when the tab is not requested. However, with this construction, the tab can also rotate around the shaft 205. The connecting element is rotatably mounted on the hoop. This allows less constrain the connecting element during the deformation of the arch.

This configuration is more particularly visible with reference to the second embodiment and in particular to the figure 7 , the mounting of the connecting element 500 being similar between the two illustrated embodiments. We will also note in figure 7 that the arch 200 has in this case, at each of these side portions 201, 202 a slot 204 substantially oriented in the direction in height corresponding to the direction "z". This slot 204 passes right through, the arch 200 at the hole 206 forming the bearing of the shaft 205 so that the first end 501 of the connecting element 500 can be inserted inside the 200 to be held by the shaft 205. The latter can, for example, be in the form of a screw whose head performs a blocking of one side of the arch 200 and cooperating with a member of opposite mounting, performing the function of a nut.

Optionally, the vertical slot 204 of each lateral portion 201, 202 of the arch 200 has edges along its height so as to provide lateral guidance of the connecting element 500. It is generally understood that the The purpose of fixing the connecting element 500 is to allow force transmission in the direction of the desired relative movement. Conversely, in the embodiments of the Figures 1 to 7 , the connecting element 500 has a mobility relative to the seat 100. More particularly, in the examples, the tab forming the connecting element 500 and having a substantially elongated shape in the direction "z", has a second end 502 adapted to be inserted into a housing 110 formed within an edge 105 or 106 of the seat 100 in which the second end 502 has a mobility capacity, in the direction of the relative movement between the arch 200 and the seat 100. An example of housing 110 is visible in the exploded view of the figure 7 at which the housing 110 is directed along the height of the host device 1 and has an upper opening placed opposite the slot 204. This upper opening is intended to be traversed by the connecting element 500 In this example, the housing 110 passes right through the seat 100 and forms a slot.

The housing 110 is dimensioned to guide the connecting element 500, and more particularly its second end 502, during the displacement of the connecting element resulting from the deformation of the arch. The second end 502 can then slide in a guide direction, substantially vertical in this example. As a result, the connecting element is able to move by sliding relative to the seat, during the relative movement of spacing or bringing together the rear lateral portion of the arch and the seat.

In the situation shown, the connecting element 500 is assembled to the entire host device 1 through a lower opening of the housing 110 opening on the lower face 102 of the seat. This lower opening is located opposite the upper opening opposite the arch 200. Thus, the element 500 can be threaded into the housing 110, on the side of the underside of the seat , so as to pass through said housing 110. The element 500 is then placed so that its first end 501 is introduced into the slot 204 of the arch 200. The first end 501 is then fixed to the arch by the shaft 205. In these cases, it is therefore between the seat 100 and the connecting element 500 that the relative freedom of movement between the seat 100 and the rear part of the arch 200 is produced.

At the same time, this freedom of movement is limited so as to avoid too much relative spacing between the two parts. For this purpose, the connecting element 500 has a stop element 503, an exemplary embodiment of which is illustrated in perspective at the figure 7 and in section in the two embodiments illustrated at the level of figures 4 and 6 . By way of example, the stop element 503 may be in the form of a projecting protuberance on one and / or the other of the faces of the second end 502 of the tab forming the element of FIG. link 500. A protuberance of circular section forming a stud on the surface of the tab may be suitable. The stop element 503 cooperates with an abutment surface 111 which is equipped with the seat 100 and in particular, in the illustrated embodiments, the housing 110 of the seat 100.

In these examples, the housing 110 defines an internal clearance volume of the second end 502 of the connecting element 500 but includes, at its opening facing the arch 200, a narrowing of section whose width the opening is slightly greater than the average thickness of the tab but less than the width at the stop element 503. Thus, the section narrowing allows the passage of most of the connecting element 500 except for the stop member 503 which corresponds to an upper width. Thus, the second end 502 of the connecting element 500 can move downwards but is blocked in translation upwards by the abutment surface 111 on which stops the stop element 503. Downwards, it is understood that, once the host device 1 once mounted on the gliding board, the upper face 11 of the gliding device defines an abutment surface for the flap so that the deflection of the second end 502 of the connecting element 500 is also bounded in this direction.

Thus, the first end 501 of the connecting element 500 is able to be secured to the arch 200 while its second end 502 is able to be secured to the seat 100.

According to one embodiment, a connecting element 500 equips each edge 105, 106 of the seat 100. By way of example, the connecting elements 500 are symmetrically arranged in the longitudinal direction of the reception device 1, direction "x". In this way, they realize a mobile connection allowing not only a movement of spacing or approximation only by rotation along the axis "y" but they can also perform a torsion movement in which a connecting element 500 located on an edge 105 or 106 is mobilized in the approximation direction while the other connecting element 500 on the other edge 106 or 105 is mobilized away or is held in position.

It will be noted that the example shown describes a connecting element 500 fixed relative to the arch 200 and movable relative to the seat 100. This configuration can be reversed within the scope of the present invention by fixing the connecting element 500 relative to the seat 100 and allowing relative freedom of movement between the first end 501 of the element 500 and the arch 200.

Furthermore, it is also possible for the two ends 501, 502 of the connecting element 500 to have a relative freedom of movement limited with respect to the arch 200 and the seat 100 respectively. housing design corresponding to the housing 110 described for the seat 100 can be reproduced at the arch 200 so as to establish, at this level, a corresponding freedom of movement.

In the examples described, each connecting element 500 passes through a slot 204 of the arch and through a housing 110 of the seat also corresponding to a slot. This construction is not limiting. A connecting element 500 may, for example, be in a laterally open housing, which may facilitate its implementation. It can be a plate comprising an oblong hole in which a pawn is lodged.

In a non-illustrated case, the bounded deflection offered by the connecting element 500 is not achieved by a relative displacement of the connecting element 500 and the seat 100 or the arch 200 but by a deformation of the connecting element 500.

In a first embodiment, this deformation means a modification of the shape of the connecting element 500, in particular by bending or buckling following compression in the direction of the relative movement of the arch 200 towards the seat 100. For this purpose, the connecting element 500 is dimensioned so as to allow this deformation by bending or buckling. The connecting element may be, for example, a substantially elongate tab and thin in a material capable of such deformation. In another case, the connecting element 500 has a capacity for elastic deformation, in particular in compression during the approach phase with respect to the seat 100. Thus, the connecting element 500 can, in this case, case, be a block of elastomeric material or rubber, a spring, in particular a compressible coil spring, or a block of foam. In this case, the ends 501, 502 of the connecting element 500 may each be fixed or secured respectively to the arch 200 and the seat 100. Advantageously, the connecting element 500 does not deform or little extension. This allows to provide rigidity in the linkage in tension and thus limit the spacing of the rear portion of the arch relative to the seat.

With reference to Figures 5 to 7 , a variant of the invention vis-à-vis the embodiment of the Figures 1 to 4 is presented. The overall configuration of the reception device 1 is similar to that presented previously. Likewise, the connecting elements 500 are there in a form equivalent to that of the Figures 1 to 4 . However, in these figures, the connecting element 500 equipping each edge of the seat 100 is coupled to a compressible element 600. One objective of the compressible element 600 is to provide damping in the relative movement of movement between the 200 and the seat 100. For this purpose, the rigidity of the compressible element 600 is chosen to be smaller than that of the tab 500. For example, it is possible to choose a compressible element 600 in the form of flexible polyurethane, made of rubber, elastomer or in the form of a spring or a polymer foam.

To obtain a satisfactory recovery of effort during the relative spacing between the arch and the seat, the tab 500 is characterized by a Young's modulus between 500 MPa and 3 000 MPa in tension. Concerning the compressible element 600, it serves as a stop when the connection between the arch and the seat. It is characterized by a Young's modulus less than 1000 MPa. Play can be provided between the compressible element and the hoop so as to increase the travel stroke during the approach between the hoop and the seat. The compressible element 600 may furthermore have a hardness of 50 to 70 shore A and preferably 60 shore A.

In the embodiment shown in Figures 5 to 7 , the compressible element 600 is intimately coupled to the connecting element 500, this case not being limiting. In these illustrations, the compressible element 600 is in the form of a sleeve defining an internal passage 602 directed in the longitudinal direction of the element 500 and configured so that the element 500 can be introduced into the passage 602. L compressible element 600 is positioned to be in contact, on the one hand, at a lower face of the arch 200, and secondly, at an upper face of the seat 100. Here, the element compressible is also placed at the slot 204 of the arch 200 and the seat 110 of the seat 100 which are the places of the connections of the connecting element 500 with the seat 100 and the arch 200. In the case shown, the sleeve forming the compressible element 600 completely surrounds the element 500 but this case is not limiting. For example, an open "U" sleeve could be suitable. Thus, by wrapping even partially the connecting element 500, the compressible element 600 can protect it from the weather.

In addition, the figures show a compressible element 600 provided with beads 601 having the function of spring turns making it possible to achieve a compressive end of travel of the compressible element 600 when the beads 601 are contiguous. Thus, the movement in the direction of approach can be limited by the compressible element 600.

By way of example, the materials used for the arch 200 and the seat 100 are polymers such as polyamide or polycarbonate.

Furthermore, it is possible to configure the docking device so as to define, for the rear part of the rollbar, a rest position corresponding to a position in which no stress is applied on the part of the user. . This rest position is configured to allow on the one hand a spreading movement of the hoop 200 according to a first defined course and on the other hand an approaching of the hoop 200 towards the seat 100 according to a second predefined course. In this case, the device is designed to obtain an asymmetrical stroke in relation to the direction of the deformation of the arch, whether during the relative spacing of a rear lateral part of the arch and the seat or whether for their relative approximation.

Preferably, the first distance course is smaller than the second approach course. The first stroke is weak and results, in the illustrated examples, a clearance between the stop member 503 and the abutment surface 111, when the rear portion of the arch is in the rest position. In a variant, the first separation stroke may be zero. In this case, the design does not allow any deformation tending to spread a rear lateral portion of the arch of the seat.

In the example described, the rest position corresponds to the inclination of the hoop relative to the seat, determined by the attachment points 107, 108, independently of the connecting elements 500. allow relative mobility both in extension and in compression around the rest position. For example, from the rest position and at the midpoint of the arch 200 (in the middle of its dimension in the longitudinal direction "x"), the upward movement can be limited to a maximum of 10 mm and preferably at 5 mm. Similarly, from the rest position, the downward displacement of the central point of the length of the arch 200 can be limited to 20 mm and preferably to 15 mm. These dimensions make it possible to obtain a good compromise between strength / resistance and flexibility of movement.

In this case, the midpoint of the arch may be closer to the seat than to deviate from it.

These latitudes of movements allow a vertical movement upwards or downwards of the rear part of the arch but also a rotational movement about a longitudinal axis of the base. These degrees of freedom provide the flexibility of movement sought by the surfer.

It is the stop elements 503 and abutment surface 111 as well as the configuration of the compressible element 600 possibly present which will determine the values of the stroke.

In summary, according to the embodiments described, the construction proposes a hoop 200 self-supported by at least one point of attachment 107, 108. The rear portion 203 of the hoop can deform substantially vertically by bending the lateral portions 201, 202 of the arch. The docking device incorporates a stop mechanism comprising a connecting element and a stop in the seat. This stop mechanism serves to limit the bending of a side portion 201, 202 of the hoop in one direction, in the direction of the spacing of the rear portion of the seat. This limitation preserves the structure of the host device because in this sense, it is highly stressed, especially at the points of attachment. Thus, the connecting element is secured in a spacing direction, both with the seat and the bow, when the rear lateral part of the bow and the seat are spaced a certain distance, in the purpose of limiting the upward movement.

Furthermore, the docking device is designed to allow greater travel in the other direction, in the direction of bringing the rear portion of the seat. In this sense, the structure is a little less constrained and therefore accepts more deformation.

One can nevertheless provide a stop mechanism. This can be achieved by the use of a compressible element 600 or by contact between the end 502 of the connecting element 500 with the upper surface 11 of the board.

The compressible element 600 may advantageously have an elastic behavior. This makes it possible to apply an elastic return to the arch to bring it back to a position of equilibrium of rest described previously. The behavior of the reception device is dynamic and improves the feelings of holding the shoe for the user. This helps him to find a more stable equilibrium position. In other words, the compressible element 600 connecting the seat 100 and the arch 200 is configured to exert a force tending to oppose the approach between the seat 100 and the arch 200 by elastic deformation.

The use of connecting elements 500 and / or compressible elements 600 separate from the seat / bow subset facilitates the customization of the behavior of the host device and its repair. Indeed, one can adapt the flexibility, the damping or the stroke of use of the device by easily changing a connecting element or an element compressible. For example, elements made of a material with different mechanical properties can be used. Similarly, it is possible to modify the location of the stop elements 503, which modifies the travel path. On the other hand, if an item is damaged, it is easy to change without having to replace the massive parts of the docking device. Maintenance is more economical.

Note that the present invention can easily integrate into a host device 1 without requiring additional parts. For example, the shaft 205 used to secure the link member 500 at the hoop 200 can also be used to articulate the rear support member 300 on the hoop 200 and to secure the back links 420. example of this mutualized embodiment is particularly visible in sectional views 4 and 6 at which the shaft 205 crosses in the direction "y" the entire width of the assembled device at the arch 200. L use of the same shaft 205 to fix the connecting element 500, the rear links 420 and / or the rear support element 300 optimizes the design by making the device more economical to achieve.

In a variant, the connecting element 500 is a cable, a strap or a wire fixed on a lateral rear part of the arch and on the seat. In this case, we obtain a limitation of the deformation of the rear part of the arch in the direction of its spacing vis-à-vis the seat while allowing its approximation.

In the embodiments described, the receiving device comprises a connecting element on each side. In a variant, there can be seen only one side equipped with a connecting element. In this case, asymmetrical behavior is favored with pivoting of the hoop about a longitudinal axis in one direction only.

An object of the invention is to provide flexibility to the surfer by allowing him more movement in the shoe while ensuring sufficient support. The additional movements are vertical movements of the heel of the shoe and lateral movements of the back of the shoe. These last degrees of freedom are similar to a rotation around a longitudinal axis of the shoe at the level of the sole. To obtain this flexibility in rotation or torsion, the receiving device must be designed so that the lateral portions of the arch surrounding the heel can have a relative vertical movement relative to each other.

As we have seen previously, the vertical relative movement of the lateral parts of the rollbar is obtained either by sliding of a connecting element in relation to the seat or the rollbar, or by deformation of the connecting element .

An alternative solution to the embodiments described above, is to cut the hoop at the rear portion 203. In other words, the right side of the hoop is not connected to the left side of the hoop, at the rear part of the arch. As a result, the device is provided with flexibility since the two lateral parts may have relative movement with respect to each other. According to one variant, the two distinct lateral parts are connected at the level of the rear part of the hoop by a flexible and / or compressible element. This allows to always get this flexibility in torsion but it brings better hold, additional support. For these last two alternatives, the lateral parts of the arch are rigidly connected to the seat, with a connection of the embedding type, or may also include a connecting system providing a little flexibility, for example, by using a similar system to the first two embodiments described.

The invention is not limited to these embodiments. It is possible to combine these embodiments.

The invention is not limited to the embodiment previously described but extends to all the embodiments covered by the appended claims.
