- thermosetting rubber allows direct assembly of the PTFE wafer 7, without glue. This assembly takes place by a surface chemical reaction at the time of vulcanization of the rubber, that is to say the last manufacturing operation which gives the rubber its shape and its final consistency.
- This operation generally takes place in a mold having the desired shape where a rubber bar is introduced, and which is heated for a determined time to activate the vulcanization reaction which causes the bread to expand in the volume of the mold. and its hardening.
- PTFE plate 7 it could be assembled with the support directly by an intimate surface connection. It has also been found that by placing a flat PTFE plate in a mold having a relief, the plate was deformed under the pressure of the rubber being vulcanized to match the shape of the wall of the mold.
- PTFE is a relatively soft material which easily lends itself to deformation by beach and even by creep.
- Figure 3 schematically illustrates this manufacturing process. It represents a mold 20 in two parts, the part 22 inversely presenting the desired relief in the end, in this case the two preceding beads.
- a PTFE plate 23 is introduced into the mold, as well as a thermosetting rubber bar 24.
- the plate 23 has in a transverse direction a width substantially equal to the width of the mold cavity, and in a longitudinal direction a dimension greater than the overall dimension of the mold, taking into account the desired final shape.
- the mold is closed and heated to activate the vulcanization of the rubber.
- the rubber expands which pushes the PTFE plate against the wall of the mold, and ensures the assembly of the support and the plate, thus giving the assembly its final shape. It may be noted that the covering of the edges 13 and 14 by the plate 7 is carried out during this operation.
- Such a manufacturing process advantageously makes it possible to produce any form of relief.
- Figures 4 to 7 show by way of illustration different forms of relief that can be produced.
- the PTFE plate is deformed according to two transverse chevrons 26.
- the PTFE wafer has a plurality of protruding pads 27.
- the relief is formed according to two curved beads 28, with a center of curvature which is located in the vicinity of the heel of the shoe.
- FIG. 7 schematizes a relief in embossing 29.
- FIG. 8 illustrates a variant according to which the support plate is produced in two layers having different properties.
- the upper layer 31 is relatively hard so as to give a firm and firm seat to the shoe.
- the lower layer 32 is thinner, more flexible with preferably damping properties. Its role is to absorb shocks and vibrations which pass between the ski and the boot during skiing.
- Such a support plate is obtained by superimposing in the mold several rubber bars which then mix intimately superficially with their contact zone.
Abstract
Description
L'invention concerne un dispositif d'appui d'une chaussure sur un ski, notamment mais non exclusivement un ski alpin.The invention relates to a device for supporting a boot on a ski, in particular but not exclusively an alpine ski.
L'invention concerne également une fixation de ski équipée d'un tel dispositif d'appui.The invention also relates to a ski binding equipped with such a support device.
Une chaussure est généralement maintenue sur un ski alpin par des éléments de fixation qui retiennent ses extrémités de façon déclenchable, c'est-à-dire qui libèrent l'une ou l'autre des extrémités lorsqu'elle exerce une contrainte excessive. Les extrémités de la chaussure reposent en outre sur des dispositifs d'appui ou plaques d'appui. Pour faciliter la libération de la chaussure, on utilise généralement des plaques d'appui à faible frottement.A shoe is generally held on an alpine ski by fastening elements which retain its ends in a triggerable way, that is to say which release one or the other of the ends when it exerts an excessive stress. The ends of the shoe also rest on support devices or support plates. To facilitate the release of the shoe, low friction bearing plates are generally used.
En particulier, la plaque d'appui utilisée pour l'extrémité avant est revêtue d'une garniture de matériau anti-friction, notamment en polytrétrafluoréthylène (qui sera désigné dans la suite PTFE).In particular, the support plate used for the front end is coated with a lining of anti-friction material, in particular polytretrafluoroethylene (which will be designated in the following PTFE).
L'assemblage de cette garniture sur son support est une opération relativement délicate à cause des propriétés anti-adhérentes du PTFE. En outre, cet assemblage doit résister aux conditions climatiques dans lesquelles les éléments de fixation évoluent, neige, rayons ultra-violets, changements de température, etc...The assembly of this lining on its support is a relatively delicate operation because of the non-stick properties of PTFE. In addition, this assembly must withstand the climatic conditions in which the fastening elements evolve, snow, ultra-violet rays, temperature changes, etc.
La demande de brevet français publiée sous le numéro 2 533 832 décrit le collage de telles garniture de PTFE au moyen d'un adhésif double face ou d'une colle de type cyanoacrylate ou isocyanate acrylique. Pour améliorer l'efficacité et la tenue du collage, la PTFE a subi sur sa face inférieure un pré-traitement de surface, par exemple un traitement au sodium naphtalène ou sodium amoniaque. En outre, des charges sont incorporées dans la matière de la plaquette pour retarder la pénétration des rayons ultra-violets, et retarder la détérioration du collage.French patent application published under the number 2,533,832 describes the bonding of such PTFE packing using a double-sided adhesive or an adhesive of cyanoacrylate or acrylic isocyanate type. To improve the effectiveness and the bonding strength, the PTFE has undergone a surface pretreatment on its underside, for example a treatment with sodium naphthalene or sodium ammonia. In addition, fillers are incorporated into the material of the wafer to delay the penetration of ultraviolet rays, and to delay deterioration of the bonding.
Cette technique donne de bons résultats, mais sa mise en oeuvre est relativement complexe et coûteuse.This technique gives good results, but its implementation is relatively complex and costly.
On connaît aussi d'après la demande de brevet français publiée sous le numéro 2 615 748 un dispositif d'appui présentant une garniture de PTFE qui est assemblée à un support par un processus mécanique, notamment par encliquetage, emboutissage, rivetage, encastrement etc....Also known from French patent application published under
Cette technique présente l'avantage d'éviter l'opération de collage. Cependant, les garnitures de PTFE n'étant plus collées, il est nécessaire que le processus d'assemblage permette d'une part un montage facile des garnitures dans leur support, et d'autre part assure une tenue fiable des garnitures dans leur support.This technique has the advantage of avoiding the bonding operation. However, since the PTFE packings are no longer glued, it is necessary for the assembly process to allow, on the one hand, easy mounting of the packings in their support, and on the other hand ensures reliable hold of the packings in their support.
En effet, dans le cas où la fixation est utilisée avec une chaussure usagée, le frottement entre les garnitures et la semelle de chaussure augmente. Il faut éviter dans ce cas que la chaussure entraîne latéralement les garnitures hors de leur support.Indeed, in the case where the binding is used with a used shoe, the friction between the linings and the shoe sole increases. In this case, the shoe must be prevented from driving the linings laterally out of their support.
Un des buts de l'invention est de proposer un dispositif d'appui d'une chaussure dont la garniture antifriction est assemblée sans collage et est fermement maintenue sur son support.One of the objects of the invention is to provide a support device for a shoe, the anti-friction lining of which is assembled without bonding and is firmly held on its support.
Un autre but de l'invention est de proposer un dispositif d'appui dont l'assemblage de la garniture sur son support est très simple.Another object of the invention is to provide a support device whose assembly of the lining on its support is very simple.
Un autre but de l'invention est de proposer un dispositif d'appui dont la forme de la surface supérieure peut être facilement façonnée.Another object of the invention is to provide a support device whose shape of the upper surface can be easily shaped.
Un autre but de l'invention est de proposer un dispositif d'appui pour lequel les qualités anti-friction sont très bonnes.Another object of the invention is to provide a support device for which the anti-friction qualities are very good.
D'autres buts et avantages apparaîtront au cours de la description qui va suivre, cette description étant donnée à titre indicatif et non limitatif.Other objects and advantages will appear during the description which follows, this description being given by way of non-limiting indication.
Conformément à l'invention, dispositif d'appui présente une plaquette de polytétrafluoréthylène (PTFE), et il est caractérisé par le fait que la plaquette PTFE est brute et qu'elle est assemblée par contact direct et intime liaison superficielle sur un support en matière thermodurcissable.According to the invention, the support device has a polytetrafluoroethylene (PTFE) plate, and it is characterized in that the PTFE plate is raw and that it is assembled by direct contact and intimate surface bonding on a material support. thermosetting.
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 est une vue générale en perspective d'une fixation avant équipée d'un dispositif d'appui selon un premier mode non limitatif de mise en oeuvre de l'invention.Figure 1 is a general perspective view of a front attachment equipped with a support device according to a first non-limiting embodiment of the invention.
La figure 2 est une vue en coupe transversale du dispositif d'appui de la figure 1.Figure 2 is a cross-sectional view of the support device of Figure 1.
La figure 3 est une vue qui illustre le mode de fabrication du dispositif d'appui.Figure 3 is a view which illustrates the manufacturing method of the support device.
Les figures 4 à 7 représentent des variantes de mise en oeuvre de l'invention.Figures 4 to 7 show alternative embodiments of the invention.
La figure 8 illustre une autre variante de l'invention.FIG. 8 illustrates another variant of the invention.
La figure 1 représente en perspective une fixation avant 1. La fixation 1 comprend un élément de fixation 2 et un dispositif d'appui 3 pour la semelle de chaussure.Figure 1 shows in perspective a front binding 1. The
L'élément de fixation est de tout type approprié, et il ne sera pas décrit en détail. Globalement, il comprend une embase 4, surmontée d'un corps 5. Le corps 5 porte vers l'arrière une mâchoire 6 de retenue de la chaussure. La fixation 1 est assemblée au ski par tout moyen approprié, par exemple des vis 6 qui traversent des orifices de l'embase.The fastener is of any suitable type, and will not be described in detail. Overall, it comprises a
Dans le mode de réalisation illustré, le dispositif d'appui 3 est rattaché à l'embase qu'il prolonge vers l'arrière. Ceci n'est toutefois pas limitatif, et le dispositif d'appui pourrait être isolé, ou associé à tout autre élément.In the illustrated embodiment, the
Le dispositif d'appui présente dans sa partie supérieure une garniture antifriction 7 qui est réalisée à partir d'une plaquette de polytétrafluoréthylène (désigné dans la suite PTFE). La plaquette de PTFE 7 est portée par un support 8 de forme globale parallélépipédique rectangle auquel elle est assemblée.The support device has in its upper part an anti-friction lining 7 which is produced from a polytetrafluoroethylene plate (hereinafter referred to as PTFE). The PTFE plate 7 is carried by a support 8 of overall rectangular parallelepiped shape to which it is assembled.
On a obtenu de meilleurs résultats avec une plaquette de PTFE qui a subi sur l'une de ces faces un pré-traitement chimique destiné à faciliter son collage. Ce pré-traitement est connu. Du PTFE brut peut aussi convenir. La plaquette peut aussi être réalisée en PTFE naturel, ou en PTFE chargé de pigments de coloration.Better results have been obtained with a PTFE plate which has undergone on one of these faces a chemical pretreatment intended to facilitate its bonding. This pre-treatment is known. Raw PTFE may also be suitable. The plate can also be made of natural PTFE, or PTFE loaded with coloring pigments.
Le support et la plaquette PTFE sont assemblés au reste de la fixation par tout moyen approprié. Selon le mode de réalisation illustré, le support repose sur une plaque de base 10 dont la partie avant s'engage sous l'embase de la fixation et est solidarisé à celui-ci. Un capot d'habillage et de maintien 11 recouvre par ailleurs le support 8 et la plaquette 7. Le capot présente une ouverture 12 dont les dimensions correspondent aux dimensions en plan de l'ensemble formé par le support 8 et la plaquette 7. Il présente une hauteur inférieure à celle du support, de telle façon que la plaquette PTFE 7 soit en saillie au dessus du capot. Le capot est assemblé à la plaque de base par tout moyen approprié, et par exemple par déformation élastique, au moyen de griffes qui s'engagent dans des logements correspondants de la plaque de base.The support and the PTFE plate are assembled to the rest of the fixing by any suitable means. According to the illustrated embodiment, the support rests on a
Avantageusement, le support 8 présente dans sa partie inférieure des rebords 13, 14 qui se logent dans des évidements correspondants 15, 16 du capot.Advantageously, the support 8 has in its
De préférence, ainsi que cela est représenté dans les figures, le plaquette PTFE descend le long des bords et des rebords 13 et 14 du support 8. La plaquette est ainsi emprisonnée le long d'au moins deux de ses bords par l'assemblage du capot, ce qui la rend moins vulnérable à l'arrachement dans ces zones.Preferably, as shown in the figures, the PTFE plate descends along the edges and
En outre, la plaquette PTFE présente un relief à sa surface supérieure. D'après les figures 1 et 2, ce relief est formé selon deux bourrelets 18, 19 longilignes, qui s'étendent selon une direction transversale.In addition, the PTFE plate has a relief on its upper surface. According to Figures 1 and 2, this relief is formed according to two
La figure 2 montre qu'en fait, la plaquette PTFE épouse le relief que son support 8 présente luimême à sa surface supérieure.Figure 2 shows that in fact, the PTFE wafer follows the relief that its support 8 itself presents on its upper surface.
Le relief de la plaquette PTFE conduit à une réduction et une fragmentation de la surface de contact entre le dispositif d'appui et la semelle de chaussure. On pense qu'une telle fragmentation de la surface de contact diminue les frottements entre la semelle de chaussure et son appui, et qu'elle améliore donc les performances de glissement du dispositif d'appui.The relief of the PTFE plate leads to a reduction and fragmentation of the contact surface between the support device and the shoe sole. It is believed that such a fragmentation of the contact surface reduces the friction between the shoe sole and its support, and that it therefore improves the sliding performance of the support device.
Le support 8 est quant à lui réalisé en une matière thermodurcissable, plus précisément en un caoutchouc thermodurcissable. Un tel matériau est avantageux car selon la composition chimique précise et le mode de réalisation du caoutchouc thermodurcissable, on peut obtenir en final une plaque support 8 relativement dure ou au contraire une plaque support relativement souple, avec le cas échéant des propriétés amortissantes. Une plaque support dure offre un appui ferme à la chaussure, une plaque support souple contribue au confort et à l'amortissement des chocs.The support 8 is for its part made of a thermosetting material, more precisely of a thermosetting rubber. Such a material is advantageous because, depending on the precise chemical composition and the embodiment of the thermosetting rubber, it is possible in the end to obtain a relatively hard support plate 8 or, on the contrary, a relatively flexible support plate, with damping properties if necessary. A hard support plate provides firm support for the shoe, a flexible support plate contributes to comfort and shock absorption.
En outre, un tel caoutchouc thermodurcissable permet un assemblage direct de la plaquette de PTFE 7, sans colle. Cet assemblage se produit par une réaction chimique superficielle au moment de la vulcanisation du caoutchouc, c'est-à-dire la dernière opération de fabrication qui donne au caoutchouc sa forme et sa consistance finale.In addition, such a thermosetting rubber allows direct assembly of the PTFE wafer 7, without glue. This assembly takes place by a surface chemical reaction at the time of vulcanization of the rubber, that is to say the last manufacturing operation which gives the rubber its shape and its final consistency.
Cette opération se déroule généralement dans un moule présentant la forme souhaitée où l'on introduit un pain de caoutchouc, et que l'on chauffe pendant un temps déterminé pour activer la réaction de vulcanisation qui provoque l'expansion du pain dans le volume du moule et son durcissement.This operation generally takes place in a mold having the desired shape where a rubber bar is introduced, and which is heated for a determined time to activate the vulcanization reaction which causes the bread to expand in the volume of the mold. and its hardening.
On s'est en plus aperçu qu'en introduisant au préalable la plaquette PTFE 7 dans le moule, on pouvait réaliser son assemblage au support directement par une intime liaison superficielle. On s'est aperçu aussi qu'en plaçant une plaquette PTFE plane dans un moule présentant un relief, la plaquette se déformait sous la pression du caoutchouc en cours de vulcanisation pour épouser la forme de la paroi du moule. Le PTFE est en effet une matière relativement tendre qui se prête facilement à une déformation par plage et même par fluage.It has also been found that by first introducing the PTFE plate 7 into the mold, it could be assembled with the support directly by an intimate surface connection. It has also been found that by placing a flat PTFE plate in a mold having a relief, the plate was deformed under the pressure of the rubber being vulcanized to match the shape of the wall of the mold. PTFE is a relatively soft material which easily lends itself to deformation by beach and even by creep.
La figure 3 illustre schématiquement ce processus de fabrication. Elle représente un moule 20 en deux parties, la partie 22 présentant de manière inversée le relief souhaité en final, en l'occurrence les deux bourrelets précédents.Figure 3 schematically illustrates this manufacturing process. It represents a
Une plaquette de PTFE 23 est introduite dans le moule, ainsi qu'un pain de caoutchouc thermodurcissable 24. Avantageusement, la plaquette 23 présente selon une direction transversale une largeur sensiblement égale à la largeur de l'empreinte du moule, et selon une direction longitudinale une dimension supérieure à la dimension hors tout du moule, compte tenu de la forme finale désirée. Cependant, on peut aussi déformer la plaquette PTFE en cloche, de façon qu'elle recouvre tous les bords latéraux de la plaque support. Le moule est refermé et chauffé pour activer la vulcanisation du caoutchouc. Le caoutchouc s'expanse ce qui repousse la plaquette PTFE contre la paroi du moule, et assure l'assemblage du support et de la plaquette, donnant ainsi à l'ensemble sa forme finale. On peut noter que le recouvrement des rebords 13 et 14 par la plaquette 7 est réalisé au cours de cette opération.A
Un tel processus de fabrication permet avantageusement de réaliser toute forme de relief.Such a manufacturing process advantageously makes it possible to produce any form of relief.
Les figures 4 à 7 représentent à titre d'illustration différentes formes de relief que l'on peut réaliser.Figures 4 to 7 show by way of illustration different forms of relief that can be produced.
Selon la figure 4, la plaquette PTFE est déformée selon deux chevrons 26 transversaux.According to FIG. 4, the PTFE plate is deformed according to two
Selon la figure 5, la plaquette PTFE présente une pluralité de pastilles 27 en saillie.According to Figure 5, the PTFE wafer has a plurality of protruding
Selon la figure 6, le relief est formé selon deux bourrelets 28 incurvés, avec un centre de courbure qui est situé dans le voisinage du talon de la chaussure.According to Figure 6, the relief is formed according to two
La figure 7 schématise quant à elle un relief en gaufrage 29.FIG. 7 schematizes a relief in
Ces formes ne sont naturellement pas limitatives, le nombre de reliefs élémentaires n'est pas non plus limitatif.These forms are naturally not limiting, the number of elementary reliefs is not limiting either.
La figure 8 illustre une variante selon laquelle la plaque support est réalisée en deux couches présentant des propriétés différentes. Par exemple, la couche supérieure 31 est relativement dure de façon à donner une assise franche et ferme à la chaussure.FIG. 8 illustrates a variant according to which the support plate is produced in two layers having different properties. For example, the
La couche inférieure 32 est plus fine, plus souple avec de préférence des propriétés amortissantes. Elle a pour rôle d'absorber les chocs et vibrations qui transitent entre le ski et la chaussure au cours de la pratique du ski.The
Une telle plaque support est obtenue en superposant dans le moule plusieurs pains de caoutchouc qui se mélangent alors intimement de façon superficielle à leur zone de contact.Such a support plate is obtained by superimposing in the mold several rubber bars which then mix intimately superficially with their contact zone.
L'invention n'est pas limitée aux différents modes de réalisation qui viennent d'être décrit, et de nombreuses variantes de mise en oeuvre sont possibles.The invention is not limited to the various embodiments which have just been described, and numerous variants of implementation are possible.
