A rubber or foam type dampening element is placed between the rear part and a snowboard.

Description

La présente invention concerne une embase pour dispositif de fixation d'une chaussure sur un snowboard, dotée d'un moyen amortisseur. Elle concerne aussi un dispositif de fixation d'une chaussure sur un snowboard et un snowboard comprenant un tel dispositif de fixation. Enfin, elle concerne aussi un procédé de fabrication d'un tel dispositif de fixation de chaussure.The present invention relates to a base for a device for attaching a boot to a snowboard, provided with a damping means. It also relates to a device for attaching a boot to a snowboard and a snowboard comprising such a fixing device. Finally, it also relates to a method of manufacturing such a shoe attachment device.

En général, les dispositifs de fixation d'une chaussure sur un snowboard comprennent une embase sensiblement horizontale en matériau plastique rigide, comprenant un moyen de fixation sur un snowboard dans sa partie centrale, permettant en général une orientation réglable. Cette embase est destinée à recevoir l'appui d'une chaussure de snowboard sur sa surface supérieure. Afin de maintenir la chaussure sur le snowboard, l'embase comprend deux parois latérales verticales représentant des éléments de retenue des surfaces latérales et médiales de la chaussure. De plus, plusieurs sangles s'étendent d'une paroi verticale vers l'autre en serrant le dessus de la chaussure pour former un maintien vertical de la chaussure, la maintenant ainsi en appui sur l'embase. A l'arrière du dispositif se trouve un élément de retenue arrière, aussi appelé par sa dénomination anglo-saxonne « spoiler ». Afin d'offrir un effet amortisseur du dispositif de fixation pour atténuer les chocs ressentis par le surfeur, il est connu de disposer une épaisseur de mousse sous toute la surface inférieure de l'embase du dispositif de fixation. En variante, une couche de mousse peut être déposée sur la surface supérieure de l'embase pour recevoir l'appui de la chaussure. Dans ce dernier cas, la mousse est visible et dotée d'éléments de décoration. Ces solutions ne sont toutefois pas satisfaisantes car elles nécessitent obligatoirement l'ajout d'un élément de mousse, ce qui augmente la complexité et le coût du procédé de fabrication du dispositif de fixation. De plus, la mousse offre un effet d'amortissement très limité et insuffisant.In general, the devices for attaching a boot to a snowboard comprise a substantially horizontal base of rigid plastic material, comprising a means of attachment to a snowboard in its central part, generally allowing an adjustable orientation. This base is intended to receive the support of a snowboard boot on its upper surface. In order to maintain the boot on the snowboard, the base comprises two vertical side walls representing retaining elements of the lateral and medial surfaces of the shoe. In addition, several straps extend from one vertical wall to the other by tightening the top of the shoe to form a vertical support of the shoe, thus maintaining it in support on the base. At the rear of the device is a rear retainer, also called by its English name "spoiler". In order to provide a damping effect of the fastening device to mitigate the shock experienced by the surfer, it is known to have a thickness of foam under the entire lower surface of the base of the fastener. Alternatively, a layer of foam may be deposited on the upper surface of the base to receive the support of the shoe. In the latter case, the foam is visible and provided with decorative elements. These solutions are however not satisfactory because they require the addition of an element of foam, which increases the complexity and cost of the method of manufacturing the fastener. In addition, the foam has a very limited and insufficient damping effect.

Un objet général de la présente invention consiste donc en un dispositif de fixation d'une chaussure sur un snowboard doté d'un moyen amortisseur, simplifié et à coût réduit.A general object of the present invention is therefore a device for attaching a boot on a snowboard with a damping means, simplified and low cost.

A cet effet, l'invention repose sur une embase pour dispositif de fixation de chaussure sur un snowboard, caractérisée en ce qu'elle présente une partie amortissante mobile par rapport au reste de l'embase afin d'amortir les efforts exercés sur la surface supérieure de l'embase.To this end, the invention is based on a base for shoe attachment device on a snowboard, characterized in that it has a damping portion movable relative to the rest of the base to dampen the forces exerted on the surface top of the base.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

  • les figures 3 et 4 représentent respectivement des vues en perspective de dessus et de dessous de l'embase du dispositif de fixation d'une chaussure sur un snowboard selon le mode d'exécution de l'invention.
These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:
  • The figure 1 represents a top view of a base of a device for attaching a boot to a snowboard according to an embodiment of the invention;
  • the figure 2 represent a side view of the base of the device for attaching a boot to a snowboard according to the embodiment of the invention;
  • the Figures 3 and 4 represent respectively top and bottom perspective views of the base of the device for attaching a boot to a snowboard according to the embodiment of the invention.

Le dispositif de fixation d'une chaussure de snowboard selon l'invention comprend une embase particulière, à laquelle sont associés les éléments habituels des dispositifs de fixation de chaussure. Ainsi, cette embase est compatible avec les différentes configurations existantes de dispositif de fixation de chaussure de snowboard. Par la suite, nous utiliserons la définition de la direction longitudinale x pour la direction horizontale sensiblement définie par la position du pied, de l'arrière vers l'avant, et de la direction transversale y pour la direction horizontale perpendiculaire.The device for attaching a snowboard boot according to the invention comprises a particular base, to which are associated the usual elements of shoe binding devices. Thus, this base is compatible with the various existing configurations of snowboard boot binding device. Later, we will use the definition of the longitudinal direction x for the horizontal direction substantially defined by the position of the foot, from the back to the front, and the transverse direction y for the perpendicular horizontal direction.

Selon le concept de l'invention, l'embase du dispositif de fixation de chaussure comprend au moins une partie qui est reliée au reste de l'embase par une frontière souple, de sorte de rendre possible un déplacement de la partie considérée par rapport au reste de l'embase, afin d'amortir les efforts transmis par un utilisateur au niveau de cette partie. Avantageusement, cette partie amortissante est disposée dans les zones de l'embase recevant les sollicitations les plus importantes du pied du surfer, comme sous le talon à l'arrière de l'embase et/ou sous la partie avant du pied.According to the concept of the invention, the base of the shoe attachment device comprises at least one part which is connected to the remainder of the base by a flexible boundary, so as to make possible a displacement of the part in relation to the rest of the base, to dampen the efforts transmitted by a user at this part. Advantageously, this damping portion is disposed in the areas of the base receiving the most important solicitations of the foot of the surfer, as under the heel at the rear of the base and / or under the front part of the foot.

Les figures illustrent plus particulièrement un mode d'exécution de l'invention, dans lequel la partie arrière 2 de l'embase 1, destinée à recevoir le talon d'une chaussure, est séparée du reste 9 de l'embase par deux échancrures latérales 3 sensiblement longitudinales et représente une partie amortissante de l'embase. Cette configuration permet de doter cette partie arrière 2 de l'embase d'une souplesse de mouvement, proche d'une rotation autour d'un axe transversal 4 positionné vers l'extrémité avant des échancrures 3, par rapport au reste de l'embase. Cette partie amortissante 2 est donc séparée du reste 9 de l'embase par une zone frontière formée par les deux échancrures 3 et l'axe transversal reliant les parties arrière de ces échancrures et matérialisé par l'axe 4.The figures illustrate more particularly one embodiment of the invention, wherein the rear portion 2 of the base 1, intended to receive the heel of a shoe, is separated from the rest 9 of the base by two lateral notches 3 substantially longitudinal and represents a damping portion of the base. This configuration makes it possible to provide this rear portion 2 of the base with a flexibility of movement, close to a rotation about a transverse axis 4 positioned towards the front end of the indentations 3, with respect to the rest of the base . This damping part 2 is thus separated from the remainder 9 of the base by a border zone formed by the two notches 3 and the transverse axis connecting the rear parts of these notches and materialized by the axis 4.

De plus, la surface inférieure 5 de la partie arrière amortissante 2 de l'embase occupe au repos une position plus haute que la surface 10 du snowboard. Pour cela, dans ce mode d'exécution, la surface inférieure 5 occupe au repos une position plus haute que la partie la plus basse 7 de l'embase. Cette partie la plus basse 7 s'étend depuis la partie centrale de l'embase, au niveau de sa zone de liaison 8 prévue pour venir reposer directement sur la surface d'un snowboard 10, jusqu'à la partie antérieure comme cela est schématiquement représenté sur la figure 2.In addition, the lower surface 5 of the damping rear portion 2 of the base occupies at rest a position higher than the surface 10 of the snowboard. For this, in this embodiment, the lower surface 5 occupies at rest a higher position than the lowest part 7 of the base. This lowest part 7 extends from the central part of the base, at its connecting zone 8 provided to rest directly on the surface of a snowboard 10, to the front as schematically represented on the figure 2 .

Dans ce mode d'exécution, la surface inférieure 5 de la partie arrière 2 de l'embase présente une légère pente vers le haut, de sorte que l'extrémité arrière 6 de cette surface se trouve au-dessus de la surface d'un snowboard d'une hauteur h d'environ 5 millimètres. En variante, une hauteur de quelques millimètres de la partie amortissante de l'embase au-dessus de la surface du snowboard 10 pourrait convenir, puisqu'elle serait dotée d'une liberté de mouvement du fait de l'espace disposé entre sa surface inférieure et la surface supérieure du snowboard. Une hauteur entre 3 et 10 millimètres conviendrait bien. En variante, la surface inférieure de la partie amortissante pourrait être sensiblement parallèle au snowboard. Elle est nécessairement détachée de la surface du snowboard, pas en contact avec cette surface du snowboard dans sa position de repos, afin d'être dotée d'un degré de liberté de mouvement vers le bas pour remplir sa fonction d'amortissement des efforts.In this embodiment, the lower surface 5 of the rear portion 2 of the base has a slight upward slope, so that the rear end 6 of this surface is above the surface of a snowboard with a height h of about 5 millimeters. Alternatively, a height of a few millimeters of the damping portion of the base above the surface of the snowboard 10 could be suitable, since it would be provided with a freedom of movement because of the space disposed between its lower surface and the upper surface of the snowboard. A height between 3 and 10 millimeters would be fine. Alternatively, the lower surface of the damping portion could be substantially parallel to the snowboard. It is necessarily detached from the surface of the snowboard, not in contact with this surface of the snowboard in its rest position, to be provided with a degree of freedom of movement down to fulfill its function of damping efforts.

Ainsi, lorsqu'un utilisateur a chaussé ce dispositif de fixation et s'engage dans une descente, il va transmettre des efforts très importants sur l'embase, notamment par l'intermédiaire de son talon. Ces efforts vont entraîner des déformations de la partie arrière 2 de l'embase, située directement sous le talon, qui va s'enfoncer sous les efforts importants subis, notamment lors des chocs, sauts, virages, etc., puis retrouver sa position naturelle selon un mouvement d'oscillation dépendant des propriétés élastiques de son matériau utilisé. Ces mouvements et oscillations vont ainsi permettre de remplir une fonction d'amortissement des efforts transmis par le surfer, qui ressentira moins de douleur notamment au niveau de ses genoux.Thus, when a user has put on this fixing device and engages in a descent, it will transmit very significant efforts on the base, including via his heel. These efforts will cause deformations of the rear portion 2 of the base, located directly under the heel, which will sink under the significant efforts suffered, especially during shocks, jumps, turns, etc., then recover its natural position according to an oscillation movement depending on the elastic properties of its material used. These movements and oscillations will thus make it possible to fulfill a damping function of the forces transmitted by the surfer, who will feel less pain especially at the level of his knees.

L'embase de l'invention peut se trouver dans un matériau rigide ou semi-rigide similaire aux matériaux utilisés dans l'état de la technique, par exemple en plastique chargé de fibres voire en métal ou en plastique non chargé rigide. En variante, d'autres matériaux rigides peuvent être utilisés. Nous entendons par partie amortissante de l'embase une partie dans ce matériau rigide ou semi-rigide, s'étendant sur toute l'épaisseur de l'embase, et non par exemple une simple couche superficielle de mousse qui serait ajoutée. Pour amplifier l'effet technique obtenu, il est possible d'envisager que la partie amortissante et le reste de l'embase se présentent dans un matériau différent. Par exemple, une telle structure pourrait être obtenue par une double injection de matériau plastique, la partie amortissante se trouvant dans un matériau moins rigide que le reste de l'embase.The base of the invention may be in a rigid or semi-rigid material similar to the materials used in the state of the art, for example fiber-filled plastic or even metal or rigid non-filled plastic. Alternatively, other rigid materials may be used. By damping part of the base we mean a part in this rigid or semi-rigid material, extending over the entire thickness of the base, and not for example a single superficial layer of foam that would be added. To amplify the technical effect obtained, it is possible to envisage that the damping part and the rest of the base are in a different material. For example, such a structure could be obtained by a double injection of plastic material, the damping portion being in a less rigid material than the rest of the base.

Bien entendu, l'effet amortissant a été obtenue par les deux échancrures 3 représentées à titre d'exemples. Il existe d'autres formes et/ ou d'autres nombres d'échancrures possibles pour obtenir des effets similaires. Par exemple, les échancrures pourraient être courbées. Il est aussi possible d'imaginer une seule échancrure dans une direction sensiblement transversale, reprenant partiellement l'axe 4 par exemple. En variante, il est possible de réaliser une seule échancrure longitudinale, pour former une solution dissymétrique d'amortissement.Of course, the damping effect has been obtained by the two notches 3 represented by way of examples. There are other shapes and / or other numbers of indentations possible to achieve similar effects. For example, the indentations could be curved. It is also possible to imagine a single notch in a substantially transverse direction, partially taking the axis 4 for example. Alternatively, it is possible to make a single longitudinal notch, to form an asymmetrical damping solution.

Selon une variante supplémentaire non représentée, il est possible d'obtenir cet effet de séparation d'une partie de l'embase par un autre moyen qu'une échancrure, par exemple par une zone de moindre épaisseur, ou une bande élastique séparant deux parties de l'embase. Dans tous les cas, une partie dite amortissante de l'embase sera au moins partiellement séparée du reste de l'embase par une zone intermédiaire dite frontière, de sorte de permettre un mouvement, une flexion, de la partie amortissante par rapport au reste de l'embase. Ainsi, cette frontière, qui correspond au contour de la partie amortissante, peut être réalisée par une zone comprenant globalement moins de matériau rigide, soit dans son épaisseur, que ce soit par des échancrures, ouvertures, ou zones de faibles épaisseurs, soit par une géométrie particulière permettant à la partie amortissante d'être reliée par peu de matériau rigide au reste 9 de l'embase, soit par l'utilisation d'un matériau plus souple, pour lui permettre de remplir sa fonction d'amortissement.According to a further variant not shown, it is possible to obtain this effect of separating a part of the base by means other than an indentation, for example by a zone of lesser thickness, or an elastic band separating two parts. of the base. In all cases, a so-called damping portion of the base will be at least partially separated from the rest of the base by an intermediate zone called boundary, so as to allow movement, bending, the damping portion relative to the rest of the base. Thus, this boundary, which corresponds to the contour of the damping portion, can be achieved by an area comprising generally less rigid material, or in its thickness, whether by notches, openings, or areas of small thickness, or by a particular geometry allowing the damping part to be connected by little rigid material to the rest 9 of the base, or by the use of a more flexible material, to enable it to fulfill its damping function.

Selon une autre variante d'exécution de l'invention, la séparation de l'embase peut concerner la partie avant de l'embase, située au dessous de l'articulation métatarsophalangienne, où s'applique l'appui avant d'un pied. Selon une autre variante, elle peut concerner des zones latérales de l'embase, lui permettant de favoriser l'effet de roulis pour offrir plus de mobilité, et des amortissements dans la direction latérale.According to another alternative embodiment of the invention, the separation of the base may relate to the front portion of the base, located below the metatarsophalangeal joint, where the front support of a foot is applied. According to another variant, it may relate to the lateral zones of the base, allowing it to promote the roll effect to offer more mobility, and damping in the lateral direction.

Bien entendu, le concept de l'invention peut être combiné à d'autres solutions existant dans l'état de la technique. Il est par exemple possible de disposer une ou plusieurs couches de mousse ou tout autre matériau élastique, comme du caoutchouc par exemple, entre la partie amortissante de l'embase et la surface du snowboard, sans sortir du concept de l'invention. Dans un tel cas, de simples bandes de mousse de petites dimensions peuvent suffire. De plus, cette mousse étant cachée et invisible, elle n'a pas besoin de présenter un aspect esthétique très recherché. Une telle présence de mousse peut par exemple présenter l'avantage d'empêcher tout choc de la partie amortissante directement sur la surface de la planche de glisse. Ces solutions avec mousse peuvent ainsi permettre d'obtenir un résultat satisfaisant avec une faible quantité de mousse. Naturellement, il est possible d'ajouter une épaisseur de mousse sur la surface de l'embase, notamment sur la surface supérieure de la partie amortissante, pour ajouter un élément de confort supplémentaire, sans sortir du concept de l'invention.Of course, the concept of the invention can be combined with other solutions existing in the state of the art. It is for example possible to have one or more layers of foam or other elastic material, such as rubber for example, between the damping portion of the base and the surface of the snowboard, without departing from the concept of the invention. In such a case, simple strips of small foam may suffice. Moreover, this foam being hidden and invisible, it does not need to present a very sought-after aesthetic appearance. Such a presence of foam may for example have the advantage of preventing any shock of the damping portion directly on the surface of the gliding board. These solutions with foam can thus provide a satisfactory result with a small amount of foam. Naturally, it is possible to add a thickness of foam on the surface of the base, in particular on the upper surface of the damping part, to add an additional comfort element, without departing from the concept of the invention.

L'invention porte aussi sur un procédé de fabrication d'une embase d'un dispositif de fixation de snowboard, qui peut comprendre une étape de réalisation d'une frontière entre deux parties de l'embase. Cette étape peut consister en la découpe d'au moins une échancrure.The invention also relates to a method of manufacturing a base of a snowboard binding device, which may comprise a step of producing a boundary between two parts of the base. This step may consist of cutting at least one notch.
