Description

Domaine TechniqueTechnical area

L'invention concerne le domaine des sports de glisse et plus précisément celui du surf des neiges ou snowboard. Il concerne plus particulièrement un élément interface mis en place entre la semelle de la chaussure et la fixation (ou la planche de surf) pour combler l'espace vide existant entre la semelle et la fixation ou la planche. De tels éléments interfaces sont couramment appelés dans le domaine du snowboard par l'expression anglaise de "gaz pedal".The invention relates to the field of snow sports and more specifically that of snowboarding or snowboarding. It relates more particularly to an interface element placed between the sole of the shoe and the binding (or the surfboard) to fill the empty space between the sole and the binding or board. Such interface elements are commonly referred to in the field of snowboarding by the English expression "gas pedal".

Dans le reste de la description, l'invention est décrite dans l'application au surf des neiges, mais elle pourrait être transposée à n'importe quel type de planche de glisse tel que ski alpin, ski de fond ou autre.In the rest of the description, the invention is described in the application to snowboarding, but it could be transposed to any type of gliding board such as downhill skiing, cross-country skiing or other.

Techniques antérieuresPrevious techniques

Comme on le sait, le surf se pratique soit avec des chaussures rigides ressemblant à des chaussures de ski alpin, soit avec des chaussures souples coopérant avec des fixations présentant les éléments rigides, notamment une gouttière arrière, destinée à procurer les appuis à la chaussure souple.As is known, surfing is practiced either with rigid shoes resembling alpine ski boots, or with soft shoes cooperating with bindings having the rigid elements, including a rear gutter, intended to provide support for the soft shoe .

L'invention se rattache plus précisément à cette famille de chaussures souples et de fixations adaptées.The invention relates more specifically to this family of soft shoes and suitable fasteners.

De telles chaussures sont en effet utilisées pour leur qualité de confort permettant à l'utilisateur de marcher sans gêne lorsqu'il a déchaussé sa planche.Such shoes are indeed used for their quality of comfort allowing the user to walk without embarrassment when he took off his board.

Or, pour permettre un bon déroulé du pied lors du mouvement de marche, les chaussures souples possèdent une semelle qui présente une légère courbure telle que les extrémités avant et arrière sont légèrement surélevées.However, to allow a good unwinding of the foot during the walking movement, the soft shoes have a sole that has a slight curvature such that the front and rear ends are slightly raised.

On conçoit donc qu'au niveau des extrémités avant et/ou arrière de la chaussure, lorsque cette dernière est mise en place sur la fixation, il existé un certain volume inoccupé entre le dessous de la semelle de la chaussure et la face supérieure de l'embase de la fixation, ou bien encore la planche de glisse proprement dite en fonction de l'architecture de la fixation utilisée.It is therefore conceivable that at the front and / or rear ends of the boot, when the latter is placed on the binding, there is a certain unoccupied space between the underside of the sole of the boot and the upper face of the boot. base of the binding, or even the gliding board itself according to the architecture of the binding used.

Ce volume exempt de matière ne permet donc pas à l'utilisateur de transmettre des efforts au niveau des extrémités avant et/ou arrière du pied, dont on sait par ailleurs, qu'elles constituent une des zones principales de transmission des appuis.This volume free of material therefore does not allow the user to transmit efforts at the front and / or rear ends of the foot, which we know, they are one of the main areas of transmission of the supports.

Il est à noter que ce problème de la transmission efficace des appuis se pose de façon plus importante au niveau de l'extrémité avant de la chaussure, puisque les appuis au niveau de l'extrémité arrière de la chaussure sont assurés de façon prépondérante par la gouttière arrière de la fixation. Néanmoins, l'absence d'appui efficace au niveau de l'arrière du talon de la chaussure provoque des imprécisions au niveau des sensations reçues et donc de la conduite du surf.It should be noted that this problem of the effective transmission of the supports is more important at the front end of the boot, since the supports at the rear end of the shoe are ensured predominantly by the rear gutter of the binding. Nevertheless, the lack of effective support at the rear of the heel of the shoe causes inaccuracies in the sensations received and therefore the conduct of the surf.

Pour résoudre ce problème, des solutions ont déjà été proposées.To solve this problem, solutions have already been proposed.

Dans le document US 5 503 900, on décrit une fixation dont l'embase comporte des éléments additionnels situés aux extrémités avant et arrière. Ces éléments forment des cales inclinées, dont la face supérieure est destinée à venir au contact de la semelle de la chaussure au niveau avant et arrière. De la sorte, les efforts exercés à proximité de la pointe de la chaussure sont transmis en direction de l'embase via cet élément formant cale. Le jeu entre la semelle de la chaussure et la face supérieure de l'embase est supprimé, ce qui permet une transmission des efforts dès les premiers mouvements de la pointe du pied. L'inconvénient majeur de ces éléments formant cale est qu'ils ne peuvent pas s'adapter à différentes tailles de chaussure, et qu'il est donc nécessaire de les repositionner à chaque fois que l'utilisateur change de chaussures.US 5,503,900 describes a fastener whose base comprises additional elements located at the front and rear ends. These elements form inclined wedges, whose upper face is intended to come into contact with the sole of the shoe at the front and rear level. In this way, the forces exerted near the tip of the shoe are transmitted towards the base via this wedge member. The game between the sole of the shoe and the upper face of the base is removed, which allows a transmission of effort from the first movements of the tip of the foot. The major disadvantage of these wedge elements is that they can not adapt to different shoe sizes, and therefore it is necessary to reposition them each time the user changes shoes.

Par ailleurs, on a proposé dans le document WO 98/42419 de rendre les cales réglables en positions longitudinale et transversale pour pouvoir s'adapter à différentes configurations de semelles. Cependant, l'élément ayant une forme déterminée, il ne peut pas correspondre à toutes les formes des semelles des chaussures sur le marché.Furthermore, it has been proposed in WO 98/42419 to make the shims adjustable in longitudinal and transverse positions to be able to adapt to different sole configurations. However, the element having a specific shape, it can not match all the shapes of the soles of the shoes on the market.

Une telle solution présente donc l'inconvénient majeur que l'élément formant cale n'est présent que sur une partie de la surface de la semelle de la chaussure, de sorte que la surface d'appui de la chaussure n'est pas intégralement utilisée et qu'une partie des efforts exercés par l'utilisateur n'est pas mis à profit.Such a solution therefore has the major disadvantage that the wedge element is only present on a part of the sole surface of the shoe, so that the bearing surface of the shoe is not fully used. and that part of the effort exerted by the user is not taken advantage of.

En outre, on observe qu'en fonction de différentes courbures de la semelle de la chaussure, il peut apparaître un certain jeu entre la semelle et l'élément formant cale. Ce jeu produit les effets néfastes précités.In addition, it is observed that depending on different curvatures of the sole of the shoe, there may appear some clearance between the sole and the wedge member. This game produces the aforementioned harmful effects.

Enfin, un certain glissement entre la surface supérieure de l'élément formant cale et la semelle peut apparaître, ce qui limite l'efficacité de la transmission des efforts.Finally, some slippage between the upper surface of the wedge member and the sole may occur, which limits the effectiveness of the transmission of forces.

Un des problèmes que se propose de résoudre l'invention est donc celui de l'optimisation du contact entre l'élément interface formant cale et la semelle de la chaussure, pour obtenir la meilleure transmission possible des efforts.One of the problems to be solved by the invention is that of the optimization of the contact between the wedge interface element and the sole of the shoe, to obtain the best possible transmission of forces.

L'invention se propose donc de fournir un élément interface destiné à être interposé entre la semelle de la chaussure et la fixation ou la face supérieure de la planche, qui procure un appui optimal quelle que soit la taille de la chaussure et sa géométrie.The invention therefore proposes to provide an interface element intended to be interposed between the sole of the boot and the binding or the upper face of the board, which provides optimal support regardless of the size of the shoe and its geometry.

Exposé de l'inventionPresentation of the invention

L'invention concerne donc un élément interface utilisé sur une planche de glisse, ledit élément étant interposé entre la semelle de la chaussure de l'utilisateur et la face supérieure de la planche, de manière à permettre la transmission des appuis exercés en direction de la planche par l'utilisateur au moins au niveau de l'extrémité avant de la semelle.The invention therefore relates to an interface element used on a gliding board, said element being interposed between the sole of the user's boot and the upper face of the board, so as to allow the transmission of the supports exerted in the direction of the board. board by the user at least at the front end of the sole.

L'élément conforme à l'invention se caractérise en ce qu'il comporte au moins une zone constituée d'un matériau thermoformable apte à épouser après exposition à la chaleur, l'empreinte d'au moins l'extrémité avant de la semelle de la chaussure, de manière à combler le volume situé entre la face supérieure de la planche et la semelle de la chaussure.The element according to the invention is characterized in that it comprises at least one zone consisting of a thermoformable material capable of marrying after exposure to heat, the impression of at least the front end of the sole of the shoe, so as to fill the volume between the upper face of the board and the sole of the shoe.

Autrement dit, l'élément caractéristique est réalisé en un matériau qui peut adopter la forme exacte du dessous de la semelle de la chaussure, ce qui assure un blocage en position extrêmement précis de la chaussure par rapport à la fixation.In other words, the characteristic element is made of a material that can adopt the exact shape of the underside of the sole of the shoe, which ensures a locking in extremely precise position of the boot relative to the binding.

La coopération des motifs de la semelle et des motifs correspondant moulés dans la zone thermoformable assure une immobilisation quasi parfaite de la chaussure par rapport à la fixation, quelle que soit la géométrie de la semelle.The cooperation of the grounds of the sole and corresponding molded patterns in the thermoformable zone ensures a near perfect immobilization of the boot relative to the binding, whatever the geometry of the sole.

En outre, le matériau thermoformable utilisé est comprimé et donc rigidifié au moment du moulage par la semelle, ce qui augmente la capacité de transmission des appuis, notamment par rapport aux dispositifs de l'Art antérieur réalisé en matériaux élastomériques.In addition, the thermoformable material used is compressed and therefore stiffened at the time of molding by the sole, which increases the transmission capacity of the supports, particularly compared to devices of the prior art made of elastomeric materials.

L'élément interface conforme à l'invention peut être mis en place soit directement au-dessus de l'embase de la fixation, soit directement au-dessus de la face supérieure de la planche lorsque l'architecture de la fixation ne comporte pas d'embase comme dans les fixations du type connu sous l'appellation de "baseless".The interface element according to the invention can be put in place either directly above the base of the binding, or directly above the upper face of the board when the architecture of the binding does not include 'base as in the fasteners of the type known as the "baseless".

L'élément interface peut également être disposé directement sur la face supérieure de la planche et traverser l'embase de la fixation dans des ouvertures réalisées à cet effet dans cette dernière.The interface element can also be arranged directly on the upper face of the board and pass through the base of the binding in openings made for this purpose in the latter.

L'élément interface conforme à l'invention peut être présent soit au niveau de l'extrémité avant de la chaussure, soit au niveau de l'extrémité arrière de cette dernière, soit encore à ces deux extrémités. Il peut encore former un seul élément couvrant toute la surface de la semelle de la chaussure en s'étendant d'une extrémité à l'autre de cette dernière.The interface element according to the invention may be present either at the front end of the shoe, or at the rear end of the latter, or at both ends. It can still form a single element covering the entire surface of the sole of the shoe extending from one end to the other of the latter.

Dans une forme avantageuse, l'élément interface comporte, au niveau des extrémités avant et/ou arrière, et en dessous de la zone en matériau thermoformable, une zone supplémentaire en un matériau rigide, de manière à assurer une bonne transmission des appuis exercés en direction de la planche.In an advantageous form, the interface element comprises, at the front and / or rear ends, and below the zone of thermoformable material, an additional zone made of a rigid material, so as to ensure a good transmission of the supports exerted in direction of the board.

En effet, selon cette caractéristique, la rigidité de l'élément interface, au niveau des extrémités avant ou arrière, est relativement importante, et cumule la rigidité de la zone thermoformable proprement dite avec celle de la zone sous-jacente.Indeed, according to this characteristic, the rigidity of the interface element, at the front or rear ends, is relatively large, and combines the rigidity of the thermoformable zone itself with that of the underlying zone.

Dans le cas où l'élément interface s'étend sous toute la longueur de la chaussure, il peut s'avérer avantageux qu'il comporte, au moins au niveau du talon, et en dessous ou à la place de la zone en matériau thermoformable, une zone en matériau souple, de manière à assurer un amortissement des vibrations en provenance de la planche, et d'amortir les chocs notamment lors de la réception des sauts.In the case where the interface element extends under the entire length of the shoe, it may be advantageous that it comprises, at least at the heel, and below or instead of the zone of thermoformable material , an area of flexible material, so as to ensure a damping of vibrations from the board, and to dampen shocks, especially when receiving jumps.

Autrement dit, l'élément interface comporte à son niveau arrière une zone relativement compressible qui absorbe une partie de l'énergie des vibrations transmises par la planche, au niveau de la semelle où la transmission des appuis n'est pas prépondérante.In other words, the interface element comprises at its rear level a relatively compressible zone which absorbs a portion of the energy of the vibrations transmitted by the board, at the level of the sole where the transmission of the supports is not preponderant.

Avantageusement en pratique, l'élément interface conforme à l'invention peut être recouvert d'une couche de protection imperméable, réalisée par exemple en un tissu enduit de polytétrafluoroéthylène. Une telle couche de protection évite à la neige, l'eau et la glace de venir s'insérer à l'intérieur des alvéoles de la mousse de l'élément thermoformable. Une telle couche de protection peut en outre recevoir un décor.Advantageously in practice, the interface element according to the invention may be covered with an impervious protective layer, made for example of a polytetrafluoroethylene coated fabric. Such a protective layer prevents the snow, water and ice from being inserted inside the cells of the foam of the thermoformable element. Such a protective layer may further receive a decoration.

Manière de réaliser l'inventionWay of realizing the invention

Comme déjà dit, l'invention concerne un élément interface destiné à être mis en place entre la semelle de la chaussure et la fixation ou la face supérieure de la planche, de manière à compenser la courbure de la semelle de la chaussure.As already mentioned, the invention relates to an interface element intended to be placed between the sole of the shoe and the attachment or the upper face of the board, so as to compensate for the curvature of the sole of the shoe.

Comme illustré à la figure 1, l'élément caractéristique (10) peut être mis en place sur l'embase (2) de la fixation (1).As illustrated in Figure 1, the characteristic element (10) can be placed on the base (2) of the fastener (1).

Dans la forme illustrée, cette embase (2) comporte un arceau arrière (3) passant derrière le pied, et recevant une gouttière (4) articulée destinée à servir d'appui arrière à la tige de la chaussure.In the form shown, this base (2) has a rear arch (3) passing behind the foot, and receiving a gutter (4) hinged to serve as a rear support to the boot upper.

Bien évidemment, l'invention n'est pas limitée à cette seule architecture de fixation, et peut notamment être utilisée dans des fixations dites "baseless" qui ne comportent pas d'embase proprement dite, mais seulement deux longerons latéraux, l'élément interface reposant alors directement sur la face supérieure de la planche (8).Of course, the invention is not limited to this single fastening architecture, and may in particular be used in so-called "baseless" fasteners which do not comprise a base itself, but only two side rails, the interface element resting then directly on the upper face of the board (8).

De la même manière, l'invention n'est pas limitée à la forme de réalisation illustrée à la figure 1, dans lequel l'élément interface (10) s'étend sur toute la surface de l'embase (2), mais elle couvre également des variantes dans lesquelles l'élément interface est présent uniquement au niveau de l'extrémité avant et/ou de l'extrémité arrière.In the same way, the invention is not limited to the embodiment illustrated in FIG. 1, in which the interface element (10) extends over the entire surface of the base (2), but it also covers variants in which the interface element is present only at the front end and / or the rear end.

Comme illustré aux figures 1 à 4, l'élément caractéristique (10) montré à titre d'exemple non limitatif, s'étend sous toute la longueur de la semelle (20).As illustrated in Figures 1 to 4, the characteristic element (10) shown by way of non-limiting example, extends under the entire length of the sole (20).

Comme déjà dit, cette semelle (20) appartient à une chaussure souple qui est notamment utilisée pour ses qualités de confort lors de la marche. Cette semelle présente, illustrée de façon exagérée, une certaine courbure, qui permet un déroulé du pied lors de la marche.As already said, this sole (20) belongs to a soft shoe which is used in particular for its qualities of comfort when walking. This sole has, illustrated exaggerated, a certain curvature, which allows a roll of the foot when walking.

Cette courbure fait que la pointe (21) de la chaussure et l'extrémité arrière (22) du talon sont légèrement surélevées par rapport au niveau le plus bas (23) de la chaussure située sensiblement de part et d'autre de la voûte plantaire. Cette différence de hauteur est de l'ordre du centimètre.This curvature causes the tip (21) of the shoe and the rear end (22) of the heel are slightly raised relative to the lowest level (23) of the shoe located substantially on either side of the arch. . This difference in height is of the order of a centimeter.

Conformément à l'invention, l'élément interface (10) présente une partie (11, 12) destinée à combler l'espace situé entre les extrémités avant (21) et/ou arrière (22) de la semelle (20), et l'embase (2) de la fixation.According to the invention, the interface element (10) has a portion (11, 12) intended to fill the space between the front (21) and / or rear (22) ends of the sole (20), and the base (2) of the binding.

Selon une caractéristique de l'invention, ces parties (11, 12) de l'élément interface (10) sont essentiellement constituées d'un matériau thermoformable, apte à se déformer sous l'action de la chaleur.According to a characteristic of the invention, these parts (11, 12) of the interface element (10) consist essentially of a thermoformable material, able to deform under the action of heat.

Grâce à cette caractéristique, l'utilisateur peut donner à la face supérieure (13) de l'élément interface (10) une forme complémentaire de celle de sa semelle (20), ce qui augmente la surface de contact entre la semelle et l'élément interface (voir figures 2 et 3).With this feature, the user can give the upper face (13) of the interface element (10) a shape complementary to that of its sole (20), which increases the contact area between the sole and the interface element (see Figures 2 and 3).

Plus précisément, lorsque la semelle présente des reliefs crantés (24), la matière thermoformable de l'élément caractéristique (11) se déforme pour s'insérer au moins en partie entre les différents reliefs (24) et constituer des zones d'accrochage (14) très efficaces.More specifically, when the sole has notched reliefs (24), the thermoformable material of the characteristic element (11) is deformed to fit at least partially between the various reliefs (24) and constitute hooking zones ( 14) very effective.

De façon plus générale, la matière thermoformable épouse le galbe particulier de la semelle (20) de manière à assurer un contact aussi efficace que possible.More generally, the thermoformable material matches the particular shape of the sole (20) so as to ensure as effective contact as possible.

En pratique, il suffit à l'utilisateur d'exposer la matière thermoformable à une source de chaleur, telle que par exemple un pistolet à air chaud, ou un four pour donner temporairement à la matière une capacité de déformation, puis d'appliquer la semelle de la chaussure sur l'élément interface en le mettant en place dans la fixation comme illustré à la figure 1. En chaussant cette dernière, et en la serrant normalement, puis en laissant refroidir afin que l'élément adopte, dans ses zones thermoformables, l'empreinte de la semelle comme illustré à la figure 2.In practice, it is sufficient for the user to expose the thermoformable material to a source of heat, such as for example a hot air gun, or an oven to temporarily give the material a deformation capacity, then to apply the sole of the shoe on the interface element by putting it in place in the binding as illustrated in FIG. 1. By fitting the latter, and by tightening it normally, and then allowing it to cool so that the element adopts, in its thermoformable zones , the footprint of the sole as shown in Figure 2.

Dans une version perfectionnée, l'élément est équipé d'une résistance électrique noyée dans la matière ou emprisonnée sous les zones thermoformables, de manière à être réchauffée par un courant électrique.In an improved version, the element is equipped with an electrical resistor embedded in the material or trapped under the thermoformable zones, so as to be heated by an electric current.

De multiples matières peuvent être utilisées pour assurer cette fonction de thermoformage, à partir du moment où leur température de ramollissement est suffisamment basse. On peut citer par exemple la mousse d'éthylène vinyle acétate à cellules fermées de type ULTRALON® de la Société ULTRALON PRODUCT.Multiple materials can be used to provide this thermoforming function, from the moment their softening temperature is sufficiently low. For example, ULTRALON® type closed cell ethylene vinyl acetate foam from ULTRALON PRODUCT.

Par ailleurs, et conformément à une autre caractéristique de l'invention, l'élément interface (10) peut comporter en-dessous des régions thermoformables (11, 12), des zones (16, 17) constituées d'une matière plastique relativement rigide destinée à assurer la transmission des appuis exercés par l'extrémité du pied en direction de la planche.Furthermore, and according to another characteristic of the invention, the interface element (10) may comprise, beneath the thermoformable regions (11, 12), zones (16, 17) made of a relatively rigid plastic intended to ensure the transmission of the support exerted by the end of the foot towards the board.

Une telle matière plastique peut être par exemple une mousse de polyuréthanne, voire un matériau massif tel que l'acrylonitrilbutadiène styrène.Such a plastic material may for example be a polyurethane foam, or even a solid material such as acrylonitrilbutadiene styrene.

De la sorte, la partie de l'élément interface (10) située à l'aplomb des extrémités (21) avant et/ou arrière (22) présente une rigidité suffisante pour que les appuis soient efficacement transmis.In this way, the portion of the interface element (10) located vertically above the ends (21) front and / or rear (22) has sufficient rigidity for the supports to be efficiently transmitted.

Complémentairement, la région intermédiaire (18) de l'élément interface, située entre les extrémités avant et arrière, à l'aplomb de la partie centrale (23) ou voûte plantaire de la chaussure, présente, en-dessous de la partie thermoformable (15), une zone en un matériau relativement plus souple, constitué d'une matière plastique amortissante.Complementarily, the intermediate region (18) of the interface element, located between the front and rear ends, directly above the central part (23) or foot arch of the shoe, has, below the thermoformable portion ( 15), an area of a relatively more flexible material made of a damping plastic material.

Une telle zone (15) peut être constituée en éthylène vinyle acétate basse densité ou en toute autre matière alvéolaire.Such a zone (15) may be made of low density ethylene vinyl acetate or any other cellular material.

De la sorte, la zone (15, 18) de l'élément interface (10) située en dessous de la voûte plantaire présente une certaine élasticité qui permet d'absorber une partie des vibrations transmises par la planche. Le confort de l'utilisateur est ainsi amélioré.In this way, the zone (15, 18) of the interface element (10) located below the plantar arch has a certain elasticity that makes it possible to absorb a portion of the vibrations transmitted by the board. The comfort of the user is thus improved.

Dans une variante, une zone amortissante peut s'étendre de façon relativement reculée vers l'arrière, jusque par exemple sous le talon. En effet, la nécessité d'une transmission efficace des appuis au niveau de l'aplomb du talon est moins importante que la transmission analogue au niveau de la pointe de la chaussure, puisque la gouttière arrière (4) de la fixation assure l'essentiel de la transmission des appuis vers l'arrière. Par contre, comme illustré à la figure 4, il peut être avantageux d'avoir sous le talon une zone très amortissante (19), en particulier lors de la réception des sauts. Une telle zone sera préférentiellement réalisée en un matériau amortisseur, viscoélastique, du type PODIANE® ou SORBOTANE® .In a variant, a damping zone may extend relatively far backwards, for example under the heel. Indeed, the need for effective transmission of the supports at the level of the heel plumb is less important than the analogous transmission at the tip of the shoe, since the rear gutter (4) of the binding ensures the essential the transmission of the supports backwards. On the other hand, as illustrated in FIG. 4, it may be advantageous to have a very damping zone under the heel (19), in particular when receiving jumps. Such a zone will preferably be made of a damping, viscoelastic material of the PODIANE® or SORBOTANE® type.

Selon une autre caractéristique de l'invention, l'élément interface peut être enveloppé d'un tissu avantageusement recouvert de polytétrafluoroéthylène destiné à assurer l'étanchéité de l'ensemble.According to another characteristic of the invention, the interface element may be wrapped with a fabric advantageously covered with polytetrafluoroethylene intended to seal the assembly.

En effet, compte tenu de la nature alvéolaire des mousses utilisées, il est préférable d'éviter que de l'eau ne pénètre cette matière et en dégrade les propriétés mécaniques lorsqu'elle gèle surtout si certains constituants de l'élément sont en mousses à cellules ouvertes. Ce tissu peut avantageusement recevoir un décor.Indeed, given the alveolar nature of the foams used, it is preferable to prevent water from entering this material and degrades the mechanical properties when it freezes especially if certain constituents of the element are foams to open cells. This fabric can advantageously receive a decoration.

Comme déjà dit, l'élément interface peut adopter de multiples architectures pour sa coopération avec la fixation et la planche de glisse.As already said, the interface element can adopt multiple architectures for its cooperation with the binding and the gliding board.

Ainsi, dans une des variantes illustrée à la figure 5, l'élément (30) interface présente une partie basse (32) qui repose sur la planche. L'élément (30) reçoit l'embase (31) de la fixation, dans des logements prévus à cet effet, de sorte que les zones thermoformables (33, 34, 35) de cet élément traversent des évidements (37) prévus entre les parties de l'embase.Thus, in one of the variants shown in Figure 5, the element (30) interface has a lower portion (32) which rests on the board. The element (30) receives the base (31) of the fastener, in housings provided for this purpose, so that the thermoformable zones (33, 34, 35) of this element pass through recesses (37) provided between the parts of the base.

Dans ce cas, l'élément caractéristique peut présenter des perçages (38) destinés à recevoir les vis de fixation (39) de l'embase (31) sur la planche proprement dite.In this case, the characteristic element may have holes (38) for receiving the fixing screws (39) of the base (31) on the board itself.

Dans la variante illustrée à la figure 2, l'élément interface (10) peut être soit collé sur l'embase, par un matériau adhésif approprié, soit présenter une forme telle qu'elle s'encastre à l'intérieur de l'embase sans nécessiter l'emploi de matériau adhésif.In the variant illustrated in Figure 2, the interface element (10) may be glued to the base, by a suitable adhesive material, or have a shape such that it fits inside the base without requiring the use of adhesive material.

Il ressort de ce qui précède que l'élément interface conforme à l'invention présente de multiples avantages, notamment celui d'optimiser la transmission des appuis des zones avant et arrière de la chaussure par l'élimination de tout jeu entre la chaussure et l'embase de la fixation. L'utilisation d'une matière thermoformable permet d'assurer une surface de contact aussi grande que possible entre la semelle et l'élément caractéristique, ce qui évite tout glissement ou tout jeu néfaste à la transmission des appuis.It follows from the foregoing that the interface element according to the invention has multiple advantages, in particular that of optimizing the transmission of the supports of the front and rear zones of the boot by eliminating any play between the boot and the boot. base of the fixation. The use of a thermoformable material ensures a contact area as large as possible between the sole and the characteristic element, which avoids any slippage or any play detrimental to the transmission of the supports.
