Description

La présente invention a pour objet un dispositif pour le montage sur un ski d'une fixation de sécurité, comprenant une butée et une talonnière indépendantes l'une de l'autre.The subject of the present invention is a device for mounting a safety binding on a ski, comprising a stop and a heel piece independent of each other.

De façon traditionnelle, une fixation de sécurité est montée sur un ski, directement au contact de la face supérieure de celui-ci. L'évolution de la technique de fabrication des skis conduit à réaliser des skis et notamment des skis de slalom dont la largeur dans la zone de patin est plus faible que précédemment. Or, la zone de patin servant d'appui à une chaussure du skieur, cette dernière déborde latéralement, de part et d'autre du ski, ce qui se traduit, en pente forte, par un appui de la chaussure sur la neige avant même que la carre correspondante du ski ait mordu la neige, entraînant un ripage du ski, pouvant entraîner un déséquilibre, voire une chute du skieur.Traditionally, a safety binding is mounted on a ski, directly in contact with the upper face thereof. The evolution of the ski manufacturing technique has led to the production of skis and in particular slalom skis whose width in the skate area is narrower than previously. However, the skate area serving as a support for a skier's shoe, the latter overflows laterally, on either side of the ski, which results in a steep slope, by pressing the boot on the snow even before the corresponding edge of the ski has bitten the snow, causing the ski to slip, which could cause an imbalance or even a fall of the skier.

Pour remédier à cet inconvénient, il a été imaginé de surélever la chaussure par rapport au ski, en interposant une plaque entre le ski et la chaussure, la fixation, butée et talonnière, étant montée sur cette plaque. Cette plaque présente l'inconvénient, outre le fait qu'elle augmente le poids de l'ensemble ski-fixation, de réaliser un bridage du ski sur la longueur de contact avec le ski. Or, il convient qu'un ski puisse se déformer le plus librement possible lors de son utilisation, pour offrir les meilleures performances.To remedy this drawback, it has been imagined to raise the boot relative to the ski, by interposing a plate between the ski and the boot, the binding, stop and heel piece, being mounted on this plate. This plate has the disadvantage, in addition to the fact that it increases the weight of the ski-binding assembly, of making a clamping of the ski over the length of contact with the ski. However, a ski should be able to deform as freely as possible during its use, to offer the best performance.

Une autre solution consiste à équiper un ski de deux cales indépendantes, fixées chacune sur la face supérieure du ski et servant au montage respectivement de la butée et de la talonnière de la fixation. S'il ne se produit pas un bridage sur la longueur de la zone de la fixation, comme dans le cas précédent, il se produit, compte tenu de l'éloignement des butée et talonnière de la surface du ski, supérieur à celui que l'on connaît dans un montage direct sur le ski, une augmentation de la force de basculement de la fixation due à l'appui élevé de la chaussure sur la fixation, ce qui se traduit par une augmentation du cambre du ski, c'est-à-dire par une augmentation de la flèche du ski modifiant le comportement de celui-ci.Another solution consists in equipping a ski with two independent wedges, each fixed on the upper face of the ski and used for mounting the toe piece and the heel piece of the binding, respectively. If a clamping does not occur along the length of the area of the fastening, as in the previous case, it occurs, count given the distance of the toe and heel from the surface of the ski, greater than that known in direct mounting on the ski, an increase in the rocking force of the binding due to the high support of the boot on the binding, which results in an increase in the camber of the ski, that is to say in an increase in the deflection of the ski modifying the behavior of the latter.

Le document DE-A-3 933 717 décrit un dispositif pour le montage sur un ski d'une fixation de sécurité selon le préambule des revendications 1 et 9, cette fixation de sécurité comprenant une butée et une talonnière indépendantes l'une de l'autre, ce dispositif étant du type comprenant deux cales destinées à être fixées sur un ski, ces deux cales servant au montage respectivement de la butée et de la talonnière de la fixation, et des moyens de liaison inextensible entre les deux cales empêchant l'écartement des deux cales, les deux cales étant destinées à être montées sur la face supérieure du ski, les moyens de liaison inextensible autorisant le rapprochement des deux cales.Document DE-A-3 933 717 describes a device for mounting on a ski a safety binding according to the preamble of claims 1 and 9, this safety binding comprising a stop and a heel piece independent of one of the other, this device being of the type comprising two wedges intended to be fixed on a ski, these two wedges serving for the mounting respectively of the stop and the heel of the binding, and inextensible connection means between the two wedges preventing the separation of the two wedges, the two wedges being intended to be mounted on the upper face of the ski, the inextensible connection means allowing the two wedges to be brought together.

Le but de l'invention est de fournir un dispositif pour le montage sur un ski d'une butée et d'une talonnière, disposées sur des cales de surélévation, sans que cette surélévation se traduise par une augmentation de la flèche du ski, et qui ne perturbe pas les mouvements de flexion du ski.The object of the invention is to provide a device for mounting a stop and a heel piece on a ski, disposed on elevation wedges, without this elevation resulting in an increase in the deflection of the ski, and which does not disturb the flexing movements of the ski.

A cet effet, le dispositif qu'elle concerne, du type précité, est caractérisé en ce que les moyens de liaison entre les cales sont constitués par au moins une tige inextensible dont chaque extrémité est associée à une cale, et destinée à être disposée longitudinalement au ski, au-dessus de la face supérieure de celui-ci et en-dessous de la face supérieure des cales avec possibilité de rapprochement des deux cales, et en ce qu'au moins l'une des extrémités de la tige est montée dans une cale avec possibilité de coulissement longitudinalement dans la cale et mise en appui contre une butée disposée du côté de la cale tourné vers le milieu de la chaussure.To this end, the device which it relates to, of the aforementioned type, is characterized in that the connecting means between the wedges are constituted by at least one inextensible rod, each end of which is associated with a wedge, and intended to be arranged longitudinally in skiing, above the upper face thereof and below the upper face of the cleats with the possibility of bringing the two cleats closer together, and in that at least one of the ends of the rod is mounted in a wedge with the possibility of sliding longitudinally in the wedge and bearing against a stop disposed on the side of the wedge facing the middle of the shoe.

Ainsi, lors du montage d'une chaussure sur un ski, le couple exercé par la butée et la talonnière se traduit par une déformation limitée du ski, en raison de l'action des moyens inextensibles constitués par au moins une tige reliant les cales supports de la butée et de la talonnière. Toutefois, ces moyens ne nuisent pas au comportement du ski en le bridant dans la zone de patin, puisqu'un rapprochement de la butée et de la talonnière est possible lors d'une déformation du ski passant dans un creux.Thus, when mounting a shoe on a ski, the torque exerted by the stop and the heel piece results in a limited deformation of the ski, due to the action of inextensible means constituted by at least one rod connecting the support wedges the toe and the heel. However, these means do not harm the behavior of the ski by restraining it in the skate area, since a bringing together of the stop and the heel piece is possible during a deformation of the ski passing through a hollow.

Avantageusement, chaque extrémité mobile de la tige présente une partie élargie, en forme de piston, montée coulissante à l'intérieur d'un évidement en forme de cylindre, le piston délimitant avec le cylindre deux chambres, dont celle située du côté de la tige contient un matériau visco-élastique dur, tandis que l'autre contient un matériau visco-élastique plus souple.Advantageously, each movable end of the rod has an enlarged part, in the form of a piston, mounted to slide inside a cylinder-shaped recess, the piston delimiting with the cylinder two chambers, including that located on the side of the rod. contains one hard visco-elastic material, while the other contains a more flexible visco-elastic material.

Le matériau visco-élastique dur peut posséder un module d'Young compris entre 109 et 1010 N/m2, tandis que le matériau visco-élastique plus souple possède un module d'Young compris entre 107 et 108 N/m2. Cet agencement rend le système pratiquement inextensible du côté du matériau visco-élastique dur, et permet, lors d'un rapprochement de la butée et de la talonnière résultant d'une déformation du ski, un amortissement élastique de cette déformation par compression du matériau visco-élastique le plus souple.The hard visco-elastic material can have a Young's modulus between 10 9 and 10 10 N / m 2 , while the softer visco-elastic material has a Young's modulus between 10 7 and 10 8 N / m 2 . This arrangement makes the system virtually inextensible on the side of the hard visco-elastic material, and allows, when the toe and the heel resulting from a deformation of the ski are brought closer together, an elastic damping of this deformation by compression of the visco material. - the most flexible elastic.

Afin de favoriser la libre flexion du ski, l'une au moins des extrémités de la tige est montée dans une cale avec possibilité d'inclinaison vis-à-vis de cette cale, soit par ménagement d'une lumière verticale dans la cale pour le passage de la tige, soit par articulation de la tige à l'intérieur de la cale autour d'un axe horizontal, parallèle à la face supérieure du ski et transversal à l'axe de celui-ci.In order to promote the free bending of the ski, at least one of the ends of the rod is mounted in a block with the possibility of tilting with respect to this block, either by providing a vertical light in the block for the passage of the rod, either by articulation of the rod inside the wedge around a horizontal axis, parallel to the upper face of the ski and transverse to the axis thereof.

Selon une autre caractéristique de l'invention, un plot de matière visco-élastique lié à la tige est destiné à être fixé sur la face supérieure du ski, sensiblement à mi-distance des deux cales. Ainsi, lors d'une flexion du ski, le plot travaille en extension-compression, ce qui provoque l'amortissement des vibrations du ski.According to another characteristic of the invention, a pad of visco-elastic material linked to the rod is intended to be fixed on the upper face of the ski, substantially halfway between the two wedges. Thus, during a flexion of the ski, the stud works in extension-compression, which causes the vibration of the ski to be damped.

Conformément à une variante d'exécution, un plot destiné à être monté sur le ski avec interposition d'une plaque de matériau visco-élastique, comporte une ouverture centrale pour le passage de la tige avec interposition d'une bague de matériau visco-élastique. La plaque travaille à l'extension-(compression) et la bague travaillant au cisaillement participent à l'amortissement des mouvements de déformation du ski, ce qui est tout à fait favorable puisque s'il ne faut pas empêcher le ski de se déformer, il faut amortir ses déformations pour limiter les vibrations parasites.According to an alternative embodiment, a stud intended to be mounted on the ski with the interposition of a plate of visco-elastic material, has a central opening for the passage of the rod with the interposition of a ring of visco-elastic material . The plate works on extension- (compression) and the ring working on shear contributes to damping the deformation movements of the ski, which is entirely favorable since if the ski must not be prevented from deforming, it is necessary to absorb its deformations to limit parasitic vibrations.

Une autre forme d'exécution de l'invention est décrite dans la revendication 9. Les deux parties de la tige engagées l'une dans l'autre peuvent être associées à des butées en matériau visco-élastique, comme indiqué précédemment.Another embodiment of the invention is described in claim 9. The two parts of the rod engaged one inside the other can be associated with stops of visco-elastic material, as indicated above.

Selon une autre forme d'exécution, les cales sont destinées à être montées sur la face supérieure du ski avec interposition de plaques de matériau visco-élastique. Ces plaques peuvent suffire à elles seules à permettre un rapprochement élastique des cales, la tige étant alors montée sans possibilité de coulissement vis-à-vis des cales, ou peuvent être mises en oeuvre en combinaison avec l'une des solutions présentées précédemment.According to another embodiment, the wedges are intended to be mounted on the upper face of the ski with interposition of plates of visco-elastic material. These plates may be sufficient on their own to allow an elastic approximation of the wedges, the rod then being mounted without the possibility of sliding with respect to the wedges, or may be implemented in combination with one of the solutions presented above.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de ce dispositif :

In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of examples not restrictive, several embodiments of this device:
  • Figure 1 is a side view of the central part of a ski and a ski boot attached thereto, with implementation of a first embodiment of the device according to the invention;
  • Figure 2 is a schematic top view with horizontal section in the axis of the rod;
  • Figure 3 is a side view of the device of Figures 1 and 2 during deformation of the ski;

  • Figure 7 is a view similar to Figure 1, showing another alternative embodiment of the device according to the invention;
  • Figures 8 and 9 are two detail views partially in section corresponding to two embodiments of the sliding mode of the two telescopic parts of a rod.

La figure 1 représente la partie centrale ou zone de patin 2 d'un ski sur la face supérieure duquel sont montées deux cales respectivement 3 et 4, réalisées en un matériau rigide, et servant pour la cale 3 au montage d'une butée 5 et pour la cale 4 au montage d'une talonnière 6, la butée 5 et la talonnière 6 étant destinées à réaliser, de façon connue en soi, la fixation d'une chaussure de ski 7.FIG. 1 represents the central part or skid zone 2 of a ski on the upper face of which are mounted two wedges 3 and 4 respectively, made of a rigid material, and serving for the wedge 3 for mounting a stop 5 and for the wedge 4 when mounting a heel piece 6, the stop 5 and the heel piece 6 being intended to carry out, in a manner known per se, the binding of a ski boot 7.

Il doit être précisé qu'à la figure 1 et aux autres figures similaires, les proportions respectives du ski, des cales, de la fixation et de la chaussure n'ont pas été parfaitement respectées, afin de mieux mettre en évidence les caractéristiques de l'invention.It should be noted that in Figure 1 and other similar figures, the respective proportions of the ski, cleats, binding and boot have not been perfectly respected, in order to better highlight the characteristics of the 'invention.

Comme montré aux figures 1 et 2, les cales 3 et 4 sont reliées par une tige 8 inextensible. L'extrémité avant 9 de la tige 8, qui est élargie, est ancrée à l'intérieur de la cale 3, tandis que son extrémité arrière élargie 10, est disposée à l'intérieur d'une cavité 12 ménagée dans la cale 4. L'extrémité arrière de la tige 8 se comporte à la façon d'un piston 10, alors que la cavité se comporte à la façon d'un cylindre. Dans la forme d'exécution représentée à la figure 2, le piston 10 prend appui, du côté de la tige 8, contre une butée rigide 13. Ainsi, lors du montage de la chaussure dans la fixation, les forces de basculement exercées par la chaussure sur la butée et la talonnière de la chaussure 7 ne peuvent pas se traduire par un écartement excessif entre la cale 3 et la cale 4, supprimant ainsi une flèche excessive du ski.As shown in Figures 1 and 2, the wedges 3 and 4 are connected by an inextensible rod 8. The front end 9 of the rod 8, which is widened, is anchored inside the wedge 3, while its widened rear end 10, is disposed inside a cavity 12 formed in the wedge 4. The rear end of the rod 8 behaves like a piston 10, while the cavity behaves like a cylinder. In the embodiment shown in FIG. 2, the piston 10 bears, on the side of the rod 8, against a rigid stop 13. Thus, during the mounting of the boot in the binding, the tilting forces exerted by the shoe on the stop and the heel of the shoe 7 can not result in an excessive spacing between the wedge 3 and the wedge 4, thus eliminating an excessive deflection of the ski.

Au contraire, lorsqu'en condition d'utilisation, le ski fléchit, comme montré à la figure 3, la tige 8 ne perturbe pas ce mouvement, du fait que son extrémité arrière 10 peut coulisser à l'intérieur de la cavité 12, en direction de l'arrière de celle-ci. Afin de permettre une inclinaison de la cale arrière 4 vis-à-vis de la tige 8, il est prévu une lumière 14 pour le passage de la tige 8 vers l'intérieur de la cale 4. Il serait possible de remplacer cette lumière verticale 14 par un axe horizontal et transversal à la longueur du ski pour le montage de l'extrémité avant 9 de la tige 8 à l'intérieur de la cale 3.On the contrary, when in use condition, the ski flexes, as shown in FIG. 3, the rod 8 does not disturb this movement, because its rear end 10 can slide inside the cavity 12, in direction of the back of it. In order to allow an inclination of the rear wedge 4 with respect to the rod 8, a light 14 is provided for the passage of the rod 8 towards the interior of the wedge 4. It would be possible to replace this vertical light 14 by a horizontal axis transverse to the length of the ski for mounting the front end 9 of the rod 8 inside the wedge 3.

La figure 4 représente une variante d'exécution du dispositif des figures 1 à 3, dans laquelle les deux extrémités de la tige sont montées avec possibilité de coulissement respectivement vis-à-vis de la cale avant 3 et vis-à-vis de la cale arrière 4. En outre, les cavités ménagées à l'intérieur des deux cales et disposées de part et d'autre des extrémités respectivement 9 et 10 de la tige 8, sont remplies de matériau visco-élastique. Le matériau visco-élastique 15, disposé du côté de la tige, est réalisé en un matériau dur, possédant un module d'Young compris entre 109 et 1010 N/m2, tandis que le matériau visco-élastique 16 disposé de l'autre côté des extrémités 9 et 10, est plus souple et possède un module d'Young compris entre 107 et 108 N/m2. Le matériau visco-élastique 15 permet un appui ferme mais non tout à fait rigide assurant la limitation de l'éloignement des cales 3 et 4, tandis que le matériau visco-élastique 16, tout en permettant le rapprochement des cales 3 et 4 lors d'un mouvement de cintrage du ski, amortit ce mouvement, ce qui est favorable pour éviter la mise en vibration du ski.4 shows an alternative embodiment of the device of Figures 1 to 3, in which the two ends of the rod are mounted with the possibility of sliding respectively vis-à-vis the front wedge 3 and vis-à-vis the rear wedge 4. In addition, the cavities formed inside the two wedges and arranged on either side of the ends 9 and 10 respectively of the rod 8, are filled with visco-elastic material. The visco-elastic material 15, placed on the side of the rod, is made of a hard material, having a Young's modulus of between 10 9 and 10 10 N / m 2 , while the visco-elastic material 16 disposed on the other side of the ends 9 and 10, is more flexible and has a Young's modulus between 10 7 and 10 8 N / m 2 . The visco-elastic material 15 allows a firm but not entirely rigid support ensuring the limitation of the distance of the wedges 3 and 4, while the visco-elastic material 16, while allowing the wedges 3 and 4 to be brought together during 'A bending movement of the ski, dampens this movement, which is favorable to avoid the vibration of the ski.

Dans la forme d'exécution représentée à la figure 5, un plot 18 de matériau visco-élastique est fixé sur la face supérieure du ski, sensiblement à mi-distance entre les cales 3 et 4. Lors d'une flexion du ski, ce plot 18 travaille en extension-compression, ce qui provoque l'amortissement des vibrations du ski.In the embodiment shown in FIG. 5, a stud 18 of visco-elastic material is fixed to the upper face of the ski, substantially halfway between the wedges 3 and 4. When the ski is bent, this stud 18 works in extension-compression, which causes the vibration of the ski to be damped.

La figure 6 représente une variante du dispositif de la figure 5. Dans ce cas, il est prévu un plot 19 réalisé en un matériau rigide comportant une ouverture centrale et longitudinale 20, dans laquelle est montée une bague 22 de matériau visco-élastique qui enserre la tige 8 et est collée sur celle-ci dans sa partie centrale. Le plot 19 est fixé sur la face supérieure du ski par l'intermédiaire d'une plaque de matériau visco-élastique 23. La plaque de matériau visco-élastique 23 travaille à l'extension-compression, tandis que la bague 22 travaille au cisaillement.6 shows a variant of the device of Figure 5. In this case, there is provided a stud 19 made of a rigid material having a central and longitudinal opening 20, in which is mounted a ring 22 of visco-elastic material which encloses the rod 8 and is glued to it in its central part. The stud 19 is fixed on the upper face of the ski by means of a plate of visco-elastic material 23. The plate of visco-elastic material 23 works with extension-compression, while the ring 22 works with shearing .

Dans la forme d'exécution représentée à la figure 7, la tige 8 dont les deux extrémités sont articulées en 24 est constituée par deux parties 8a et 8b télescopiques, la partie 8a étant susceptible de coulisser à l'intérieur de la partie 8b.In the embodiment shown in FIG. 7, the rod 8, the two ends of which are articulated at 24, is constituted by two telescopic parts 8a and 8b, the part 8a being capable of sliding inside the part 8b.

La figure 8 représente une première possibilité, selon laquelle l'extrémité 26 de la partie 8a est susceptible, lors du montage de la chaussure sur le ski, de venir en appui contre une butée 27, tout en étant susceptible, lors d'un mouvement de rapprochement des deux cales 3 et 4 dû à une déformation du ski, de coulisser à l'intérieur d'une cavité 28.FIG. 8 represents a first possibility, according to which the end 26 of the part 8a is susceptible, during the mounting of the boot on the ski, to come into abutment against a stop 27, while being capable, during a movement of approach of the two wedges 3 and 4 due to a deformation of the ski, to slide inside a cavity 28.

Dans la forme d'exécution représentée à la figure 9, la butée 27a est réalisée en un matériau visco-élastique dur, d'une dureté correspondant à celle indiquée précédemment en référence à la butée 15 de la figure 4, tandis que la cavité 28 est partiellement remplie d'un matériau visco-élastique 29, plus souple que le matériau visco-élastique 27a, d'une dureté comparable au matériau visco-élastique 16 défini en référence à la figure 4.In the embodiment shown in Figure 9, the stop 27a is made of a hard visco-elastic material, of a hardness corresponding to that indicated above with reference to the stop 15 of Figure 4, while the cavity 28 is partially filled with a visco-elastic material 29, more flexible than the visco-elastic material 27a, with a hardness comparable to the visco-elastic material 16 defined with reference to FIG. 4.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif de conception simple, permettant de rehausser la surface de montage de la butée avant et de la talonnière d'un ski, tout en évitant de donner à ce ski une flèche excessive modifiant le comportement de celui-ci.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a device of simple design, making it possible to raise the mounting surface of the front stop and the heel of a ski, while avoiding to give this ski an excessive arrow modifying its behavior.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes de réalisation.As it goes without saying, the invention is not limited to the sole embodiments of this device, described above by way of examples, on the contrary it embraces all of the variant embodiments thereof.
