Description

PLAQUE D'APPUI POUR UNE CHAUSSURE, NOTAMMENT UNE CHAUSSURE DE SKI SUPPORT PLATE FOR A SHOE, ESPECIALLY A SKI SHOE
L'invention concerne une plaque d'appui pour une chaussure notamment une chaussure utilisée dans les sports de glisse tels que le ski.The invention relates to a support plate for a shoe, in particular a shoe used in sliding sports such as skiing.
Ces sports se pratiquent avec des planches de glisse sur lesquelles les chaussures du skieur sont retenues en appui par des éléments de retenue. De plus, chaque chaussure repose sur une surface d'appui spécialement aménagée pour la recevoir. Habituellement, la chaussure repose sur deux plaques d'appui respectivement situées vers l'extrémité avant et l'extrémité arrière de la chaussure.These sports are practiced with gliding boards on which the skier's shoes are retained in support by retaining elements. In addition, each shoe rests on a support surface specially arranged to receive it. Usually, the shoe rests on two support plates located respectively towards the front end and the rear end of the shoe.
Pour les plaques d'appui associées à un élément déclenchable de retenue de la chaussure, il est important de réduire le plus possible les frottements de glissement entre la chaussure et son appui. Ces frottements peuvent en effet retarder la libération de la chaussure. Dans ce but, certaines plaques sont revêtues d'une pellicule ou plaquette de matériau antifriction, par exemple du polytétrafluoréthylène. Une telle plaque est connue d'après la demande de brevet en France publiée sous le numéro 2 150314.For the support plates associated with a triggering element for retaining the shoe, it is important to reduce as much as possible the sliding friction between the shoe and its support. This friction can indeed delay the release of the shoe. For this purpose, certain plates are coated with a film or plate of anti-friction material, for example polytetrafluoroethylene. Such a plate is known from the patent application in France published under the number 2 150314.
D'autres plaques d'appui présentent la particularité d'avoir une surface supérieure montée de façon oscillante autour d'un axe d'articulation longitudinal. Ainsi, la demande de brevet français publiée sous le numéro 2656225 décrit une plaque d'appui avec une plaque supérieure montée à pivotement autour d'un axe longitudinal par rapport à une plaque inférieure. Des blocs de matériau amortisseur maintiennent par ailleurs la partie supérieure dans une position nominale horizontale. Ce dispositif permet d'améliorer le confort du skieur. On pense aussi qu'un tel dispositif contribue à la protection du skieur dans certaines configurations de chute, en particulier des chutes dites avant-torsion. On pense en effet qu'un tel dispositif facilite la libération de la chaussure et évite que les genoux du skieur soient affectés de lésions sérieuses.Other bearing plates have the particularity of having an upper surface mounted in an oscillating fashion around a longitudinal articulation axis. Thus, the French patent application published under number 2656225 describes a support plate with an upper plate pivotally mounted about a longitudinal axis relative to a lower plate. Blocks of damping material also maintain the upper part in a nominal horizontal position. This device improves the comfort of the skier. It is also believed that such a device contributes to the protection of the skier in certain fall configurations, in particular so-called pre-twist falls. It is believed that such a device facilitates the release of the boot and prevents the skier's knees from being affected by serious injuries.
Un des inconvénients de cette construction est sa relative complexité. En effet, elle met en oeuvre deux plaques supérieure et inférieure reliées entre elles par un axe d'articulation. De plus, cette construction présente de nombreux interstices dans lesquels la neige et les salissures peuvent pénétrer et bloquer ainsi son fonctionnement.One of the drawbacks of this construction is its relative complexity. Indeed, it implements two upper and lower plates connected together by a hinge pin. In addition, this construction has many gaps in which snow and dirt can penetrate and thus block its operation.
L'invention vise à perfectionner un tel dispositif. Ainsi, un des buts de l'invention est de proposer une plaque d'appui de ce type dont la construction est particulièrement simple.The invention aims to improve such a device. Thus, one of the objects of the invention is to propose a support plate of this type whose construction is particularly simple.
Un autre but de l'invention est de proposer une plaque d'appui qui offre une meilleure protection contre la neige et la glace.Another object of the invention is to provide a support plate which offers better protection against snow and ice.
Ces buts sont atteints, selon la revendication 1, en construisant la plaque d'appui selon trois zones pleines juxtaposées, une zone médiane et deux zones latérales. La zone médiane est relativement rigide, pour soutenir la chaussure, et une au moins des zones latérales est elastiquement déformable pour s'affaisser sous l'effet d'une sollicitation en basculement latérale la chaussure.These objects are achieved, according to claim 1, by constructing the support plate according to three juxtaposed solid zones, a central zone and two lateral zones. The middle zone is relatively rigid, to support the shoe, and at least one of the lateral zones is elastically deformable to collapse under the effect of a lateral tilting stress on the shoe.
Un autre but de l'invention est de proposer une plaque d'appui qui ne génère qu'un frottement réduit pour la chaussure en cas de libération latérale.Another object of the invention is to provide a support plate which generates only reduced friction for the shoe in the event of lateral release.
Un but secondaire de l'invention est de proposer un plaque d'appui dont la fabrication est relativement simple. Ce but est atteint selon l'invention en réalisant les zones latérales par surmoulage sur la zone centrale.A secondary object of the invention is to provide a support plate whose manufacture is relatively simple. This object is achieved according to the invention by making the lateral zones by overmolding on the central zone.
D'autres buts et avantages de l'invention apparaîtront au cours de la description qui va suivre.Other objects and advantages of the invention will emerge during the description which follows.
L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below and to the accompanying drawings which form an integral part thereof.
La figure 1 représente à titre d'illustration de l'invention une plaque d'appui associée à un élément de fixation avant de ski alpin.FIG. 1 shows, by way of illustration of the invention, a support plate associated with a front binding element for downhill skiing.
La figure 2 représente en coupe par un plan vertical et transversal une plaque d'appui selon une mise en oeuvre non limitative de l'invention.Figure 2 shows in section through a vertical and transverse plane a support plate according to a non-limiting implementation of the invention.
La figure 3 illustre le fonctionnement de la plaque d'appui de la figure 2.FIG. 3 illustrates the operation of the support plate of FIG. 2.
La figure 4 représente une variante de réalisation.Figure 4 shows an alternative embodiment.
Les figures 5 à 8 représentent d'autres variantes de réalisation.Figures 5 to 8 show other alternative embodiments.
A titre d'illustration non limitative de l'invention, la figure 1 représente un élément de fixation avant 1. Cet élément est d'un type connu et ne sera pas décrit en détail. Il présente une mâchoire 2 de retenue de la chaussure portée par un corps 3. Le corps est monté sur une embase 4 qui est destinée à être solidarisée au ski. L'embase est prolongée vers l'arrière par une plaque d'appui 5 sur laquelle la semelle de chaussure vient reposer. Généralement, la plaque d'appui est située un peu en arrière de la mâchoire, et c'est une zone normalisée de l'avant de la semelle de chaussure qui repose sur elle.By way of nonlimiting illustration of the invention, FIG. 1 represents a front fixing element 1. This element is of a known type and will not be described in detail. It has a shoe retaining jaw 2 carried by a body 3. The body is mounted on a base 4 which is intended to be secured to the ski. The base is extended rearward by a support plate 5 on which the shoe sole comes to rest. Generally, the backing plate is located a little behind the jaw, and it is a standardized area of the front of the shoe sole which rests on it.
Les figures 2 et 3 représentent une section transversale de la plaque d'appui 5 selon un premier mode de mise en oeuvre de l'invention. Dans ces figures, on a schématisé par le trait mixte 6 la semelle de chaussure.Figures 2 and 3 show a cross section of the support plate 5 according to a first embodiment of the invention. In these figures, there is shown diagrammatically by the dashed line 6 the shoe sole.
Selon ce mode de mise en oeuvre, la plaque d'appui présente trois zones juxtaposées selon une direction transversale, c'est-à-dire une zone médiane 7 bordée par deux zones latérales 8 et 9.According to this embodiment, the support plate has three zones juxtaposed in a transverse direction, that is to say a central zone 7 bordered by two lateral zones 8 and 9.
La zone médiane 7 est ici située vers le milieu de la largeur de la chaussure. Chaque zone latérale s'étend depuis un côté de la zone médiane jusqu'au bord extrême de la plaque d'appui.The middle zone 7 is here located towards the middle of the width of the shoe. Each lateral zone extends from one side of the central zone to the extreme edge of the support plate.
La zone médiane est formée par un barreau de matériau rigide.The middle zone is formed by a rod of rigid material.
Les deux zones latérales sont quant à elles réalisées en une matière elastiquement déformable.The two lateral zones are made of an elastically deformable material.
Les trois zones sont pleines, c'est-à-dire qu'elles ne laissent pas d'ouverture ou de vide où la neige et les salissures pourraient pénétrer.The three zones are full, that is to say that they do not leave an opening or void where snow and dirt could penetrate.
La largeur de la zone médiane et la rigidité du matériau sont choisis pour que la zone médiane soit apte à supporter le poids du skieur qui est transmis à ce niveau par la semelle de chaussure. Ainsi que cela est illustré dans la figure 2, la zone médiane peut présenter une surface supérieure sensiblement bombée.The width of the median zone and the rigidity of the material are chosen so that the median zone is able to support the weight of the skier which is transmitted at this level by the shoe sole. As illustrated in FIG. 2, the middle zone can have a substantially convex upper surface.
Le barreau est orienté selon la direction longitudinale définie par l'élément de fixation. Il peut cependant être légèrement incliné par rapport à cette direction. De plus, ses flancs latéraux 7a, 7b, peuvent être parallèles ou bien convergents ou divergents. Selon une direction longitudinale, la surface supérieure du barreau sur laquelle la chaussure prend appui peut être plane ou bombée.The bar is oriented in the longitudinal direction defined by the fixing element. It can however be slightly inclined with respect to this direction. In addition, its lateral flanks 7a, 7b, may be parallel or else convergent or divergent. In a longitudinal direction, the upper surface of the bar on which the shoe rests can be flat or curved.
La dureté du matériau des zones latérales est choisie pour que la zone en question s'affaisse sous l'effet d'une sollicitation en vrillage latéral de la chaussure. Ceci est illustré en figure 3. La dureté du matériau des zones latérales peut être identique ou différente pour les deux zones.The hardness of the material of the lateral zones is chosen so that the zone in question collapses under the effect of a stress in lateral twisting of the shoe. This is illustrated in Figure 3. The hardness of the material of the lateral zones can be identical or different for the two zones.
Dans le cas d'un vrillage latéral, la chaussure bascule autour de sa partie centrale qui est supportée par la zone médiane de la plaque d'appui, et sa partie vers l'extérieur s'abaisse. La forme bombée du barreau médian 7 facilite le basculement de la chaussure, et évite en tous les cas un basculement autour d'une arrête vive.In the case of a lateral twist, the shoe rocks around its central part which is supported by the middle zone of the support plate, and its part towards the outside is lowered. The rounded shape of the median bar 7 facilitates the tilting of the shoe, and in any case avoids a tilting around a sharp edge.
On pense qu'une telle possibilité de mouvement de la chaussure facilite sa libération dans certaines configurations de chute, en particulier une chute avant-torsion avec un vrillage de la chaussure dans sa fixation, et que la protection des genoux du skieur se trouve ainsi améliorée.It is believed that such a possibility of movement of the boot facilitates its release in certain fall configurations, in particular a pre-torsional fall with a twist of the boot in its binding, and that the protection of the skier's knees is thus improved. .
De préférence, ainsi que cela est illustré dans les figures 2 et 3, les zones médianes et latérales sont recouvertes d'une pellicule de matériau anti-friction 10, par exemple du polytétrafluoréthylène. Cette plaquette forme une sorte de peau souple à la surface supérieure de la plaque d'appui.Preferably, as illustrated in FIGS. 2 and 3, the median and lateral zones are covered with a film of anti-friction material 10, for example polytetrafluoroethylene. This plate forms a kind of flexible skin on the upper surface of the support plate.
En outre, selon un mode préférentiel de réalisation, les zones médianes et latérales de la plaquette sont portées par une embase 11 qui présente des rebords latéraux 12 remontant le long des bords des zones latérales sur une partie de leur épaisseur. Ces rebords empêchent notamment un fluage du matériau déformable vers l'extérieur lors de l'affaissement d'une zone latérale.In addition, according to a preferred embodiment, the median and lateral zones of the wafer are carried by a base 11 which has lateral flanges 12 rising along the edges of the lateral zones over part of their thickness. These edges prevent in particular a creep of the deformable material towards the outside during the collapse of a lateral zone.
L'assemblage entre les différents éléments de la plaque d'appui 5 est réalisé par tout moyen approprié. Avantageusement, le barreau médian et matériau des zones latérales sont compatibles, c'est-à-dire que le matériau des zones latérales est surmoulé sur le barreau 7 de la zone médiane, et l'assemblage de la plaquette antifriction est réalisé lors de la vulcanisation ou de la polymérisation du matériau des zones latérales. Par exemple, le barreau médian est réalisé en un matériau connu sous la dénomination commerciale "Delrin", ou en polyamide chargé de fibres de verre, par exemple un polyamide connu sous la dénomination commerciale "Rilsan", et les zones latérales sont réalisées en caoutchouc thermodurcissable.The assembly between the different elements of the support plate 5 is carried out by any suitable means. Advantageously, the median bar and material of the lateral zones are compatible, that is to say that the material of the lateral zones is molded onto the rod 7 of the median zone, and the anti-friction plate is assembled during the vulcanization or polymerization of the material of the lateral zones. For example, the median bar is made of a material known under the trade name "Delrin", or of polyamide loaded with glass fibers, for example a polyamide known under the trade name "Rilsan", and the lateral zones are made of rubber thermosetting.
La figure 4 illustre une variante de réalisation selon laquelle la zone médiane est réalisée selon un barreau 13 en matériau elastiquement déformable, de dureté supérieure cependant à la dureté des zones latérales 14 et 15. Le matériau du barreau médian peut aussi présenter des caractéristiques amortissantes.FIG. 4 illustrates an alternative embodiment according to which the median zone is produced according to a bar 13 of elastically deformable material, of hardness greater however than the hardness of the lateral zones 14 and 15. The material of the median bar can also have damping characteristics.
De cette façon, en plus de la possibilité de basculement latéral, la plaque d'appui présente une souplesse relative selon une direction verticale, et le cas échéant des propriétés d'amortissement vertical.In this way, in addition to the possibility of lateral tilting, the support plate has relative flexibility in a vertical direction, and where appropriate vertical damping properties.
Avantageusement, le matériau du barreau médian 13 et celui des zones latérales 14 et 15 sont compatibles, c'est-à-dire que les zones latérales sont formées par surmoulage sur le barreau central. Par exemple, la zone médiane et les deux zones latérales sont formées en deux temps par deux moulages ou injections successifs.Advantageously, the material of the central bar 13 and that of the lateral zones 14 and 15 are compatible, that is to say that the lateral zones are formed by overmolding on the central bar. For example, the middle zone and the two lateral zones are formed in two stages by two successive moldings or injections.
Par exemple, le barreau médian est réalisé en caoutchouc thermodurcissable de dureté élevée, et les zones latérales sont réalisées en caoutchouc thermodurcissable de dureté moins élevée.For example, the middle bar is made of thermosetting rubber of high hardness, and the lateral zones are made of thermosetting rubber of lower hardness.
La figure 5 représente une variante de réalisation selon laquelle le barreau 16 qui forme la zone médiane est bombé également à sa surface inférieure. L'affaissement d'une zone latérale amène dans ce cas le barreau à pivoter sur lui-même sur une faible amplitude. La figure 6 représente une autre variante selon laquelle le barreau médian 18 se prolonge de façon continue jusque l'un des bords de la plaque d'appui. De l'autre côté se trouve une zone latérale 19 relativement moins dure que le barreau 18.FIG. 5 represents an alternative embodiment according to which the bar 16 which forms the middle zone is also curved on its lower surface. The collapse of a lateral zone in this case causes the bar to pivot on itself over a small amplitude. FIG. 6 represents another variant according to which the median bar 18 is extended continuously as far as one of the edges of the support plate. On the other side is a relatively less hard side area 19 than the bar 18.
La figure 7 illustre une variante de réalisation. Selon cette variante, le barreau médian 21 est sensiblement plus large, et il occupe une position décentrée par rapport à l'axe longitudinal médian de l'élément de fixation. Par exemple, le barreau 21 est décalé vers l'intérieur du pied. La zone latérale 23 est de ce fait moins large que l'autre zone latérale 22. Ainsi, le basculement du pied vers l'extérieur est plus facile que vers l'intérieur. Comme le représente la figure 7, le barreau 21 peut présenter une surface supérieure inclinée.Figure 7 illustrates an alternative embodiment. According to this variant, the median bar 21 is substantially wider, and it occupies an off-center position relative to the median longitudinal axis of the fixing element. For example, the bar 21 is offset towards the inside of the foot. The lateral zone 23 is therefore narrower than the other lateral zone 22. Thus, the tilting of the foot outwards is easier than inwards. As shown in Figure 7, the bar 21 may have an inclined upper surface.
La figure 8 représente en section transversale une plaque d'appui selon une variante de mise en oeuvre de l'invention.Figure 8 shows in cross section a support plate according to an alternative embodiment of the invention.
Selon cette variante, l'embase 25 et la zone médiane 26 sont monobloc.According to this variant, the base 25 and the central zone 26 are in one piece.
L'embase présente sur chaque bord latéral un rebord 27, 28, qui s'élève sur une partie de la hauteur de la plaque d'appui.The base has on each lateral edge a flange 27, 28, which rises over part of the height of the support plate.
Les rebords 27, 28, présentent dans leur partie supérieure un repli 29, 30, qui s'étend vers l'intérieur.The flanges 27, 28 have in their upper part a fold 29, 30, which extends inwards.
De chaque côté de la zone médiane 26 se trouve une zone latérale 27, 28, occupée par deux blocs de matériau elastiquement déformable. Ce matériau est par exemple un caoutchouc thermodurcissable.On each side of the central zone 26 is a lateral zone 27, 28, occupied by two blocks of elastically deformable material. This material is for example a thermosetting rubber.
Ces blocs sont par exemple posés sur le fond de l'embase. Ils peuvent aussi être assemblés à l'embase par un collage ou des moyens mécaniques.These blocks are for example placed on the bottom of the base. They can also be assembled to the base by gluing or mechanical means.
La plaque d'appui présente dans sa partie supérieure une plaquette 32 qui recouvre les différentes zones.The support plate has in its upper part a plate 32 which covers the different zones.
Avantageusement, le long de ses bords latéraux, la plaquette 32 présente des flancs 33 et 34 qui redescendent et qui s'engagent sous les replis 29 et 30. Les flancs assurent l'assemblage de la plaquette au support.Advantageously, along its lateral edges, the plate 32 has flanks 33 and 34 which descend and which engage under the folds 29 and 30. The flanks ensure the assembly of the plate to the support.
La plaquette est réalisée en un matériau flexible. De préférence, elle présente dans la région de la zone médiane 26 des lignes de pliages de faible épaisseur 36 qui sont orientées longitudinalement.The plate is made of a flexible material. Preferably, it has in the region of the central zone 26 thin fold lines 36 which are oriented longitudinally.
Ces lignes facilitent la flexion de la plaquette à ce niveau lorsque l'une ou l'autre des zones latérales s'affaisse.These lines facilitate the bending of the insert at this level when one or the other of the lateral zones collapses.
Une pellicule de matériau antifriction 40 est assemblée à la surface supérieure de la plaquette, par tout moyen approprié, par exemple par collage.A film of anti-friction material 40 is assembled to the upper surface of the wafer, by any suitable means, for example by gluing.
Cette pellicule se déforme avec la flexion de la plaquette.This film deforms with the bending of the wafer.
Il va de soi que les différentes variantes de réalisation qui ont été décrites peuvent être combinées. De plus, l'invention n'est pas limitée aux différents modes de réalisation qui ont été décrits, et de nombreuses autre variantes sont possibles.It goes without saying that the various variant embodiments which have been described can be combined. In addition, the invention is not limited to the various embodiments which have been described, and many other variants are possible.
En particulier, le dispositif qui vient d'être décrit peut être associé à tout dispositif d'appui avant ou arrière d'une chaussure, en particulier à un palpeur ou une pédale d'actionnement d'un mécanisme, par exemple un mécanisme de compensation. En outre, la pellicule de matériau antifriction pourrait être remplacée par des profilés orientés longitudinalement ou transversalement. In particular, the device which has just been described can be associated with any front or rear support device for a shoe, in particular with a feeler or a pedal for actuating a mechanism, for example a compensation mechanism. . In addition, the film of anti-friction material could be replaced by profiles oriented longitudinally or transversely.
