Description

PLAQUE D'APPUI DE CHAUSSURE POUR FIXATION DE SKI SHOE SUPPORT PLATE FOR SKI BINDING
L'invention concerne une plaque d'appui pour chaussure, qui est destinée à être associée à un élément avant de fixation de ski.The invention relates to a shoe support plate, which is intended to be associated with a front ski binding element.
D'une manière générale, une chaussure est retenue sur un ski par un élément de fixation avant et un élément de fixation arrière. Elle repose en outre au niveau de son extrémité avant sur une plaque d'appui qui est associée à l'élément de fixation avant. Dans sa partie arrière, elle repose également sur un support associé à l'élément de fixation arrière.Generally, a shoe is retained on a ski by a front binding element and a rear binding element. It also rests at its front end on a support plate which is associated with the front fixing element. In its rear part, it also rests on a support associated with the rear fixing element.
Les plaques d'appui actuellement connues comprennent une embase qui présente dans sa partie supérieure une couche de matériau à faible coefficient de frottement, sur laquelle repose la semelle de chaussure. Cette couche est par exemple constituée par la surface supérieure d'une plaquette en polytétrafiuoroéthylène.The currently known support plates include a base which has in its upper part a layer of material with a low coefficient of friction, on which the shoe sole rests. This layer is for example formed by the upper surface of a polytetrafluoroethylene plate.
Une telle plaque d'appui est par exemple décrite dans le brevet français n° 2 533 832, ainsi que le brevet français n° 2 615 748. Le premier document décrit un assemblage de la plaquette antifriction sur une embase par collage, alors que le second document est relatif à l'assemblage par un moyen mécanique, tel que l'encliquetage.Such a support plate is for example described in French patent no. 2,533,832, as well as French patent no. 2,615,748. The first document describes an assembly of the anti-friction plate on a base by gluing, while the second document relates to assembly by mechanical means, such as snap-fastening.
La plaquette antifriction est soumise de la part de la chaussure à des contraintes élevées, en particulier lors de l'engagement de la chaussure dans la fixation, ou alors lors de la libération latérale de la chaussure.The anti-friction plate is subjected on the part of the shoe to high stresses, in particular during the engagement of the shoe in the binding, or else during the lateral release of the shoe.
En outre, il est connu que l'assemblage de la plaquette antifriction à l'embase se détériore avec le temps, et il arrive que certaines plaquettes antifriction se détachent, partiellement ou complètement, de leur embase.In addition, it is known that the assembly of the anti-friction plate to the base deteriorates over time, and it happens that certain anti-friction plates detach, partially or completely, from their base.
Ainsi, il est important de pouvoir démonter une plaque d'appui pour l'échanger avec une plaque neuve.Thus, it is important to be able to dismantle a support plate to exchange it with a new plate.
Le brevet européen n° 404848 décrit une telle plaque d'appui démontable. Toutefois, l'inconvénient de ce dispositif est que l'assemblage de la plaque d'appui à l'élément de fixation est réalisé au moyen des deux vis arrière d'assemblage de la fixation sur le ski. Ainsi, l'échange de la plaque d'appui nécessite le dévissage partiel puis le revissage de ces vis. Une telle opération détériore l'accrochage de ces vis dans le ski, et de ce fait, l'assemblage de la fixation sur le ski. Egalement, dans ce dispositif, c'est l'embase toute entière qui est changée, et à ce sujet, il convient de remarquer que si la plaquette antifriction peut être endommagée, l'embase elle-même n'est pas abîmée le plus souvent.European patent n ° 404848 describes such a removable support plate. However, the drawback of this device is that the assembly of the support plate to the binding element is carried out by means of the two rear screws for assembling the binding to the ski. Thus, the exchange of the support plate requires partial unscrewing and then re-screwing of these screws. Such an operation deteriorates the attachment of these screws in the ski, and therefore the assembly of the binding on the ski. Also, in this device, it is the entire base which is changed, and on this subject, it should be noted that if the anti-friction plate can be damaged, the base itself is not damaged most often .
Un autre prob'ème qui peut se poser réside dans le choix du matériau de l'embase. En effet, cette embase c .me . : doit supporter des contraintes mécaniques de la part de la chaussure. D'autre part, elle doit être compatible avec le mode d'assemblage de la plaquette antifriction. Ainsi, pour un assemblage par collage de la plaque antifriction, il est nécessaire de choisir un matériau déterminé pour l'embase compatible avec le moyen utilisé pour l'assemblage. Or, ce matériau n'est pas toujours compatible avec les contraintes mécaniques auxquelles la plaque d'appui est soumise de la part de ia chaussure. A ce sujet, il convient de remarquer que ia solution d'assemblage mécanique de la plaquette aπtifriciion, telle qu'elle est décrite dans le brevet français n° 2 615 748, n'est pas prise er considération par la présente invention qui ne considère que les assemblages par collage, ou les assemblages de type chimique. En d'autres termes, selon l'invention, l'assemblage de la plaquette antifriction sur son support est définitif, c'est-à-dire qu'une fois assemblée, la plaquette antifriction ne peut pas être détachée de son support sans provoquer sa détérioration ou celle de son support. Un des buts de l'invention est de proposer une plaque d'appui dont la partie qui porte la plaquette aπtifriction peut être facilement interchangée.Another problem that may arise is the choice of the base material. Indeed, this base c .me. : must withstand mechanical stress on the part of the shoe. On the other hand, it must be compatible with the method of assembling the anti-friction plate. Thus, for an assembly by gluing of the anti-friction plate, it is necessary to choose a determined material for the base compatible with the means used for the assembly. However, this material is not always compatible with the mechanical stresses to which the support plate is subjected on the part of the shoe. In this regard, it should be noted that the mechanical assembly solution of the plate, as described in French Patent No. 2,615,748, is not taken into consideration by the present invention which does not consider that bonding, or chemical type assemblies. In other words, according to the invention, the assembly of the anti-friction plate on its support is final, that is to say that once assembled, the anti-friction plate cannot be detached from its support without causing its deterioration or that of its support. One of the aims of the invention is to provide a support plate whose part which carries the friction plate can be easily interchanged.
Un autre but de l'invention est de proposer une plaque d'appui dont l'échange ne nécessite pas le démontage de l'ensemble de l'embase.Another object of the invention is to provide a support plate whose exchange does not require the disassembly of the entire base.
Un autre but de l'invention est de proposer une plaque d'appui dont l'embase peut répondre à des contraintes de nature totalement différente en particulier vis-à-vis du mode d'assemblage de la plaquette antifriction, et des sollicitations mécaniques auxquelles la chaussure soumet la plaque d'appui. D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, cette description étant toutefois donnée à titre indicatif et non limitatif.Another object of the invention is to provide a support plate, the base of which can respond to constraints of a totally different nature, in particular with regard to the method of assembling the anti-friction plate, and the mechanical stresses to which the shoe submits the backing plate. Other objects and advantages of the present invention will appear during the description which follows, this description being however given by way of non-limiting indication.
La plaque d'appui, associée à un élément avant de fixation de ski, est destinée à supporter la partie avant d'une chaussure, présentant une embase s'étendant en arrière du socle de l'élément de fixation, et solidaire de celui-ci, une plaquette antifriction sur laquelle repose la semelle de chaussure, la plaquette antifriction étant interchangeable. Cette plaque d'appui est caractérisée par le fait que l'embase comprend une plaque de base, et un support de la plaquette antifriction indépendant de la plaque de base, que la plaquette antifriction est assemblée de manière définitive sur le support, et que le support est assemblé de manière amovible à la plaque de base par des moyens d'emboîtement mutuel et des moyens de verrouillage réversibles.The support plate, associated with a front ski binding element, is intended to support the front part of a boot, having a base extending behind the base of the binding element, and integral with it. ci, an anti-friction plate on which the shoe sole rests, the anti-friction plate being interchangeable. This support plate is characterized by the fact that the base comprises a base plate, and a support of the anti-friction plate independent of the base plate, that the anti-friction plate is assembled definitively on the support, and that the support is removably assembled to the base plate by means of mutual interlocking and reversible locking means.

On a représenté dans la figure 1 un élément avant de fixation 1 , dont le socle 2 est destiné à être solidarisé à un ski par tout moyen approprié, et par exemple au moyen de vis.FIG. 1 shows a front fixing element 1, the base 2 of which is intended to be secured to a ski by any suitable means, and for example by means of screws.
Le socle 2 est prolongé vers l'arrière par une plaque d'appui 3 dont les éléments principaux sont une embase 4 et une plaquette en matériau antifriction 5, comme par exemple une plaquette en résine Le socle 2 est prolongé vers l'arrière par une plaque d'appui 3 dont les éléments principaux sont une embase 4 et une plaquette en matériau antifriction 5, comme par exemple une plaquette en résine fluorée ou polytétrafluoroéthyiene. La plaquette 5 adhère à l'embase 4 par tout moyen approprié autre qu'un moyen d'assemblage mécanique, par exemple, elle adhère par collage au moyen d'une colle cyano-acrylate ou isocyanate-acrylique, ou alors elle adhère par un processus de soudure.The base 2 is extended rearward by a support plate 3, the main elements of which are a base 4 and a plate made of anti-friction material 5, such as for example a resin plate The base 2 is extended rearwards by a support plate 3, the main elements of which are a base 4 and a plate made of anti-friction material 5, such as for example a plate made of fluorinated resin or polytetrafluoroethylene. The wafer 5 adheres to the base 4 by any suitable means other than a mechanical joining means, for example, it adheres by bonding using a cyano-acrylate or isocyanate-acrylic adhesive, or else it adheres by a welding process.
D'une manière plus générale, la plaquette 5 est assemblée sur son support de façon définitive, c'est-à-dire qu'elle ne peut être détachée sans être détériorée ou sans détériorer son support.More generally, the wafer 5 is assembled on its support definitively, that is to say that it cannot be detached without being damaged or without deteriorating its support.
En se référant à la figure 2, la plaque d'appui 3 comprend une plaque de base 6, qui est reliée de manière solidaire au socle 2 de la fixation, ainsi qu'un support amovible 7. Dans l'exemple représenté, la plaque de base 6 est constituée par une lame de matériau 8 qui se replie sur elle-même et qui se referme par un soufflet élastique 9. Une telle plaque de base est connue, et elle présente, grâce au soufflet 9 et à l'élasticité du matériau qui constitue la lame, une grande amplitude de compression selon une direction verticale. Le matériau qui constitue la lame 8 doit donc par nécessité présenter une aptitude à la déformation élastique. Un tel matériau peut être un métal, ou alors par exemple une matière plastique connue sous le nom de "DELRIN", qui est réputée pour son élasticité, et sa mémoire, c'est-à-dire son aptitude à revenir à sa forme initiale après une déformation. Par contre, un tel matériau n'est pas compatible avec l'assemblage par collage d'une plaquette antifriction, au moyen d'une colle de type cyano-acrylate.Referring to Figure 2, the support plate 3 comprises a base plate 6, which is integrally connected to the base 2 of the attachment, as well as a removable support 7. In the example shown, the plate base 6 is constituted by a blade of material 8 which folds back on itself and which closes with an elastic bellows 9. Such a base plate is known, and it has, thanks to the bellows 9 and the elasticity of the material which constitutes the blade, a large amplitude of compression in a vertical direction. The material which constitutes the blade 8 must therefore necessarily have an aptitude for elastic deformation. Such a material can be a metal, or then for example a plastic material known as "DELRIN", which is known for its elasticity, and its memory, that is to say its ability to return to its initial shape. after a deformation. On the other hand, such a material is not compatible with the assembly by gluing of an anti-friction plate, using a glue of the cyano-acrylate type.
La plaque d'appui 3 présente en outre un support 7 c, .; porte la plaquette antifriction 5. Le support 7 présente en plan des dimensions qui lui permettent de recouvrir ia partie supérieure de la plaque de base 6, au moins dans sa zone arrière. Il présente en outre de préférence deux flancs latéraux 9 qui descendent sur les bords de la plaque de base 6.The support plate 3 also has a support 7 c,.; carries the anti-friction plate 5. The support 7 has planar dimensions which allow it to cover the upper part of the base plate 6, at least in its rear region. It also preferably has two lateral flanks 9 which descend on the edges of the base plate 6.
Etant donné que le support 7 est destiné à porter la plaquette antifriction 5, il est réalisé en un matériau compatible avec le mode d'assemblage de la plaquette. Par exemple, le support 7 est réalisé en une matière plastique connue sous la dénomination "ABS", et la plaquette antifriction est collée sur ce support au moyen d'une colle cyano-acrylate, ou de type isocyanate-acrylique. Un tel matériau, connu sous le nom "ABS", est compatible avec le collage o? la plaquette antifriction, mais ce matériau ne pourrait pas convenir pour réaliser ia plaque de base 6, étant donné que ce matériau ne présente pas les caractéristiques d'élasticité et de mémoire exigées au niveau de ia plaque de base 6. Le support 7 est assemblé de manière amovible à la plaque d'appui 6 par des moyens complémentaires d'emboîtement mutuel, et des moyens réversibles de verrouillage. Les moyens d'emboîtement opèrent selon une direction globalement longitudinεSince the support 7 is intended to carry the anti-friction plate 5, it is made of a material compatible with the method of assembling the plate. For example, the support 7 is made of a plastic material known under the name "ABS", and the anti-friction plate is bonded to this support by means of a cyano-acrylate adhesive, or of the isocyanate-acrylic type. Such a material, known as "ABS", is compatible with bonding where? the anti-friction plate, but this material would not be suitable for producing the base plate 6, since this material does not have the elasticity and memory characteristics required at the level of the base plate 6. The support 7 is assembled removably to the support plate 6 by complementary means of mutual interlocking, and reversible locking means. The nesting means operate in a generally longitudinal direction
Les moyens d'emboîtement comprennent pour le support 7 quatre taquets 10 situés sous le support, approximativement au niveau de chacun de ses coins. Les taquets 10 sont prolongés vers ie bas et vers l'avant par des languettes 11 qui s'étendent horizontalement.The fitting means comprise for the support 7 four tabs 10 located under the support, approximately at each of its corners. The tabs 10 are extended downwards and forwards by tongues 11 which extend horizontally.
Au niveau de la plaque de base 6, les moyens d'emboîtement comprennent deux évidements avant 12, et deux évidements arrière 13, qui sont situés dans des emplacements correspondants aux emplacements des taquets 10 du support 7. L'épaisseur de la plaque de base 6, au niveau des évidements 12 et 13, est sensiblement égale à la hauteur des taquets 10. L'emboîtement du support sur la plaque de base 6 s'opère en présentant le support de telle façon que les taquets 10 et leurs languettes 11 s'engagent dans les évidements 12 et 13. Une fois cet engagement réalisé, l'emboîtement se réalise par un simple mouvement du support 7 vers l'avant. Les taquets constituent alors une butée du support 7 pour un mouvement vers l'avant, et tout mouvement latéral. Les languettes constituent, quant à elles, une butée pour un mouvement vertical vers le haut. L'assemblage du support 7 sur la plaque de base 6 est par ailleurs réalisé par des moyens de verrouillage. Ces moyens comprennent, pour la plaque de base 6, une languette élastique 16, orientée vers l'avant. Cette languette est destinée à coopérer avec une butée 18 située sous le support 7. Lors de la mise en place du support 7, cette butée 18 vient se positionner juste en avant de la languette 16, si bien que cette languette, en prenant appui en arrière de la butée 18, empêche tout mouvement vers l'arrière du support 7.At the base plate 6, the fitting means comprise two front recesses 12, and two rear recesses 13, which are located in locations corresponding to the locations of the tabs 10 of the support 7. The thickness of the base plate 6, at the level of the recesses 12 and 13, is substantially equal to the height of the cleats 10. The nesting of the support on the base plate 6 is effected by presenting the support in such a way that the tabs 10 and their tongues 11 engage in the recesses 12 and 13. Once this engagement has been achieved, the nesting is carried out by a simple movement of the support 7 forward. The tabs then constitute a stop for the support 7 for a forward movement, and any lateral movement. The tabs constitute, for their part, a stop for a vertical movement upwards. The assembly of the support 7 on the base plate 6 is also carried out by locking means. These means comprise, for the base plate 6, an elastic tongue 16, oriented towards the front. This tongue is intended to cooperate with a stop 18 located under the support 7. When the support 7 is put in place, this stop 18 comes to be positioned just in front of the tongue 16, so that this tongue, taking support in rear of the stopper 18, prevents any movement towards the rear of the support 7.
Le support 7 présente juste en arrière de cette butée 18, et donc au niveau de la languette 16 une ouverture 19, au travers de laquelle, la lame 20 d'un outil tel qu'un tournevis peut être introduite. Par cette ouverture, la lame 20 peut donc accéder à la languette élastique 16, et faire pression vers le bas sur cette languette pour la faire fléchir, de façon à ce que la butée 18 échappe de sa retenue. Avantageusement, la languette 16 présente dans sa partie avant un rebord 22. Ainsi, l'engagement de l'outil dans l'ouverture 19 provoque le fléchissement de la languette élastique 16, et si l'outil est ensuite basculé vers l'arrière, en prenant appui sur un rebord 22 de la languette élastique 16, la lame 20 de l'outil provoque le dégagement vers l'arrière du support 7. Ainsi, pendant une manoeuvre très simple, le support 7 peut être facilement démonté de la plaque de base 6, et un nouveau support peut être ensuite emboîté et verrouillé sur la plaque de base.The support 7 has just behind this stop 18, and therefore at the level of the tongue 16 an opening 19, through which the blade 20 of a tool such as a screwdriver can be introduced. Through this opening, the blade 20 can therefore access the elastic tongue 16, and press down on this tongue to make it bend, so that the stop 18 escapes from its retention. Advantageously, the tongue 16 has in its front part a flange 22. Thus, the engagement of the tool in the opening 19 causes the elastic tongue 16 to bend, and if the tool is then tilted backwards, by bearing on a flange 22 of the elastic tongue 16, the blade 20 of the tool causes the rearward release of the support 7. Thus, during a very simple operation, the support 7 can be easily removed from the plate base 6, and a new support can then be fitted and locked on the base plate.
Les figures 6 à 10 illustrent un autre mode de réalisation de l'invention. Selon cette variante, la plaque antifriction 25 est assemblée de façon définitive sur un support 27, et le support 27 est emboîté dans la plaque de base 26 selon une direction globalement verticale. La plaque de base 26 présente, dans sa partie supérieure, un évidement central 28 dont les dimensions correspondent aux dimensions du support 27. Le support 27 est engagé dans l'évidement 28 de la plaque de base selon une direction approximativement verticale. Un rebord en saillie 31 situé sur le bord avant du support 27 est engagé sous la surface supérieure de la plaque de base 26. Au niveau du bord arrière du support, une lèvre élastique 29 munie d'un rebord en saillie 30 assure le verrouillage réversible du support 27 dans la plaque de base 26.Figures 6 to 10 illustrate another embodiment of the invention. According to this variant, the anti-friction plate 25 is assembled definitively on a support 27, and the support 27 is fitted into the base plate 26 in a generally vertical direction. The base plate 26 has, in its upper part, a central recess 28 whose dimensions correspond to the dimensions of the support 27. The support 27 is engaged in the recess 28 of the base plate in an approximately vertical direction. A protruding rim 31 situated on the front edge of the support 27 is engaged under the upper surface of the base plate 26. At the rear edge of the support, an elastic lip 29 provided with a protruding rim 30 ensures reversible locking of the support 27 in the base plate 26.
L'évidement central 28 présente, dans la zone de la lèvre 29, une découpe transversale 34 dans laquelle la lame d'un outil tel qu'un tournevis (schématisé en 32 dans la figure 8) peut être introduite pour dégager la lèvre 29 et le rebord 30 et, par un mouvement de basculement de l'outil, pour extraire le support 27 de l'évidement 28. . Selon une variante de réalisation illustrée en figure 9, un bloc de matériau élastiquement compressible 33 est placé sous le support 27 au fond de l'évidement 28 de telle façon que le support sort en appui sur le bloc 33. Sous l'action d'une poussée verticale de la chaussure vers le bas, le support 27 peut solliciter à la compression le bloc 33. Dans cette variante, les moyens d'emboîtement du support 27 dans la plaque de base 26 constituent aussi des moyens de guidage du support 27 dans la plaque de base 26 pour son mouver^nt vertical. Selon la dureté du bloc 33, on peut obtenir un effet d'amortissement plus ou moins sensible de l'appui avant de la chaussure.The central recess 28 has, in the region of the lip 29, a transverse cut 34 in which the blade of a tool such as a screwdriver (shown diagrammatically at 32 in FIG. 8) can be inserted to release the lip 29 and the rim 30 and, by a tilting movement of the tool, to extract the support 27 from the recess 28.. According to an alternative embodiment illustrated in FIG. 9, a block of elastically compressible material 33 is placed under the support 27 at the bottom of the recess 28 so that the support comes out to bear on the block 33. Under the action of a vertical thrust of the shoe downwards, the support 27 can compress the block 33 under compression. In this variant, the means for fitting the support 27 into the base plate 26 also constitute means for guiding the support 27 in the base plate 26 for its vertical movement. Depending on the hardness of block 33, a more or less noticeable damping effect can be obtained from the front support of the shoe.
La figure 10 illustre une autre variante de réalisation selon laquelle la lèvre élastique 35 qui assure le verrouillage réversible du support 27 fait partie de la plaque de base 26. L'outil est alors introduit dans l'évidement de la plaque de base, entre la lèvre 35 et le support 27 pour provoquer le dégagement de la lèvre et l'extraction du support.FIG. 10 illustrates another alternative embodiment according to which the elastic lip 35 which ensures the reversible locking of the support 27 forms part of the base plate 26. The tool is then introduced into the recess of the base plate, between the lip 35 and the support 27 to cause the release of the lip and the extraction of the support.
Naturellement, la présente description n'est donnée qu'à titre indicatif, on pourrait adopter d'autres mises en oeuvre de celle-ci sans pour autant sortir du cadre de l'invention. Naturally, the present description is given for information only, other implementations of it could be adopted without departing from the scope of the invention.
