Abstract

The plate has a fixed body (11) with a triggering mechanism e.g. release spring, for releasing a ski boot by opening the plate when the force is greater than predetermined threshold. A lever (12) has jaws (14), in its anterior part, cooperated with a heel of the boot, where openings (20) are provided on the lever. The lever is rotatably mounted around a rotation axle (13) with respect to the body for occupying two positions corresponding to open and closed positions of the plate. The axle is maintained at the body of the plate. An independent claim is also included for a method for fabricating a heel plate for a ski boot.

Description

L'invention concerne une talonnière de fixation de sécurité de type « à corps fixe » pour chaussure de ski, c'est à dire un dispositif destiné à maintenir de manière sécurisée l'arrière d'une chaussure sur un ski en exerçant une pression sur le talon de la chaussure tout en pressant vers l'avant l'ensemble de la chaussure contre un dispositif de fixation avant, et en assurant une libération automatique de l'arrière de la chaussure en cas de chute du skieur vers l'avant. Elle concerne aussi un ski sur lequel est fixée une telle talonnière et un procédé de fabrication d'une telle talonnière.The invention relates to a "fixed body" type safety binding heel for a ski boot, that is to say a device intended to securely hold the back of a boot on a ski by exerting pressure on the ski boot. the heel of the shoe while pressing forward the entire shoe against a front attachment device, and ensuring an automatic release of the back of the shoe in case of skier's fall forward. It also relates to a ski on which is fixed such a heel and a method of manufacturing such a heel.

Une première famille de talonnières de l'art antérieur, dites « à corps mobile », repose sur un corps mobile pouvant occuper une position fermée et une position ouverte, comprenant à son extrémité avant une mâchoire pour agripper le talon d'une chaussure dans la position fermée et dans sa partie arrière un mécanisme pour mettre en oeuvre la fonction de déclenchement qui permet de libérer l'arrière de la chaussure en cas d'effort important comme c'est le cas dans une chute du skieur vers l'avant. Ce corps est mobile pour occuper la position fermée de pratique du ski et la position ouverte dans laquelle le skieur peut enlever sa chaussure. Des exemples de talonnières selon cette première famille sont décrits dans les brevets FR2765115 et EP0893146 , qui décrivent un corps cylindrique tubulaire comprenant à une extrémité un agrippe talon, articulé en rotation autour d'une came formée dans une pièce cylindrique faisant partie d'un étrier en forme de U dont les deux bras sont reliés à une plaque montée pivotante sur le ski. Ce corps tubulaire met en oeuvre la fonction de déclenchement, qui permet de libérer l'arrière de la chaussure en cas d'effort important comme c'est le cas dans une chute du skieur vers l'avant. Pour cela, il comprend généralement un ressort hélicoïdal travaillant en compression entre un piston en appui sur la came et une butée située vers l'extrémité opposée à la came. La forme de la came est telle que sous l'effet de pression du ressort, la chaussure une fois chaussée est pressée vers l'avant contre la fixation avant et vers le bas contre le ski. Seul un effort important permet de basculer le corps autour de la came en repoussant le piston et en comprimant le ressort, ce qui déclenche l'ouverture de la talonnière. Ces talonnières, très coûteuses, reposent sur un corps unique réunissant toutes les fonctions essentielles de la fixation, et présentent des déclenchements qui permettent de déclencher la fixation à des efforts très élevés, particulièrement adaptés au ski de compétition.A first family of heels of the prior art, called "moving body", rests on a movable body that can occupy a closed position and an open position, comprising at its front end a jaw to grip the heel of a shoe in the closed position and in its rear part a mechanism for implementing the release function that allows to release the back of the shoe in case of significant effort as is the case in a skier's fall forward. This body is movable to occupy the closed position of skiing and the open position in which the skier can remove his shoe. Examples of heels according to this first family are described in the patents FR2765115 and EP0893146 , which disclose a tubular cylindrical body comprising at one end a heel gripper, articulated in rotation about a cam formed in a cylindrical part forming part of a U-shaped stirrup whose two arms are connected to a plate pivotally mounted on ski. This tubular body uses the trigger function, which releases the back of the shoe in case of significant effort as is the case in a skier's fall forward. For this, it generally comprises a coil spring working in compression between a piston resting on the cam and a stop located towards the end opposite the cam. The shape of the cam is such that under the effect of spring pressure, the shoe once pavement is pressed forward against the binding before and down against the ski. Only a large effort can tilt the body around the cam by pushing the piston and compressing the spring, which triggers the opening of the heel. These heels, very expensive, are based on a single body combining all the essential functions of the binding, and have triggers that trigger the attachment to very high efforts, particularly suitable for ski racing.

La présente invention s'intéresse à une seconde famille de talonnières, dites « à corps fixe », moins coûteuses du fait de leur nature très différente, plus simple, reposant sur un corps fixe comprenant le mécanisme de déclenchement de la talonnière et sur un élément distinct plus simple, mobile en rotation par rapport à ce corps, de type levier, comprenant à son extrémité avant une mâchoire pour agripper le talon d'une chaussure. La rotation de ce « levier mâchoire » par rapport au corps fixe permet à la talonnière d'occuper les deux positions fermées et ouvertes pour fixer ou libérer une chaussure de ski. Le document FR2784902 présente un exemple d'une telle talonnière, illustrée sur la figure 1. Les deux positions ouvertes et fermées de la talonnière sont obtenues par la rotation d'un levier mobile 2, autour d'un axe 3 du corps fixe 1 comprenant le mécanisme de déclenchement. Le levier 2 comprend des mâchoires 4 dans sa partie antérieure et sa partie arrière 5 permet son actionnement pour l'ouverture de la mâchoire 4. Selon les solutions de l'art antérieur, ce levier mâchoire 2 chevauche le corps 1 et comprend donc latéralement, notamment au niveau de l'axe 3, des bras latéraux 6 de faible épaisseur. Cette construction présente plusieurs inconvénients :

  • d'abord, les bras latéraux 6 de faible épaisseur imposent au levier 2 d'être dans un matériau de grande rigidité pour que les bras résistent aux différentes contraintes subies, comme le boutrolage de l'axe métallique 3 lors de la fabrication de la talonnière puis les coups de carres des skis lors de la pratique du ski ainsi que les efforts de la chaussure sur la talonnière, puisque l'effort du skieur vers le ski transite par les mâchoires 4 du levier 2 puis par l'axe 3 de la talonnière, par l'intermédiaire des bras 6 ;
  • d'autre part, les mâchoires 4 du levier 2 nécessitent un matériau possédant un coefficient de frottement particulier pour permettre le glissement et la libération de la chaussure lors d'un déclenchement de la fixation. Or les leviers 2 de l'art antérieur présentent une forme nécessitant une quantité importante du matériau répondant aux deux contraintes de rigidité et de coefficient de frottement, ce qui est coûteux :
  • enfin, cette solution impose des talonnières larges, peu adaptées à la diminution de la largeur des skis.
The present invention is concerned with a second family of heels, called "fixed body", less expensive because of their very different nature, simpler, resting on a fixed body comprising the trigger mechanism of the heel and on an element distinct simpler, movable in rotation relative to this body, lever type, comprising at its front end a jaw to grip the heel of a shoe. The rotation of this "jaw lever" relative to the fixed body allows the heel to occupy the two closed and open positions to fix or release a ski boot. The document FR2784902 presents an example of such a heel, illustrated on the figure 1 . The two open and closed positions of the heel are obtained by the rotation of a movable lever 2, about an axis 3 of the fixed body 1 comprising the trigger mechanism. The lever 2 comprises jaws 4 in its front part and its rear part 5 allows its actuation for the opening of the jaw 4. According to the solutions of the prior art, this jaw lever 2 overlaps the body 1 and comprises therefore laterally, especially at the axis 3, side arms 6 of small thickness. This construction has several disadvantages:
  • firstly, the thin side arms 6 impose on the lever 2 to be in a material of high rigidity so that the arms resist the various stresses undergone, such as the clogging of the metal shaft 3 during the manufacture of the heel then the strokes of the skis during the practice of skiing and the efforts of the shoe on the heel, since the effort of the skier to the ski passes through the jaws 4 of the lever 2 and the axis 3 of the heel through the arms 6;
  • on the other hand, the jaws 4 of the lever 2 require a material having a particular coefficient of friction to allow the sliding and the release of the boot when triggering the binding. But the levers 2 of the prior art have a shape requiring a large amount of material that meets the two constraints of rigidity and friction coefficient, which is expensive:
  • finally, this solution imposes wide heels, unsuitable for reducing the width of the skis.

L'objet de la présente invention est de proposer une talonnière à corps fixe qui ne présente pas les inconvénients précédents.The object of the present invention is to provide a fixed body heel which does not have the above disadvantages.

Plus précisément, un objet de l'invention consiste à proposer une talonnière à corps fixe moins coûteuse tout en conservant une rigidité optimale et plus généralement une bonne performance.More specifically, an object of the invention is to provide a less expensive fixed body heel while maintaining optimum rigidity and more generally a good performance.

L'invention atteint les objets ci-dessus en proposant le maintien de l'axe de rotation sur le corps fixe et non plus sur le levier, ce qui permet en outre la simplification du levier,The invention achieves the above objects by proposing the maintenance of the axis of rotation on the fixed body and not on the lever, which also allows the simplification of the lever,

Plus précisément, l'invention porte sur une talonnière de fixation de sécurité pour chaussure de ski pouvant occuper au moins deux positions, une position ouverte et une position fermée dans laquelle elle est apte au maintien sécurisé d'une chaussure de ski pour la pratique du ski, la talonnière comprenant un corps occupant la même position dans chacune de ces deux positions de la talonnière, le corps comprenant un mécanisme de déclenchement pour permettre la libération de la chaussure par l'ouverture de la talonnière en cas d'effort supérieur à un seuil prédéterminé, la talonnière comprenant en outre un levier comprenant des mâchoires dans sa partie antérieure, aptes à coopérer avec le talon d'une chaussure de ski, le levier étant monté mobile en rotation par rapport au corps autour d'un axe afin d'occuper deux positions différentes correspondant aux deux positions ouverte et fermée de la talonnière, au moins une extrémité de l'axe de rotation étant maintenue au niveau du corps de la talonnière, caractérisée en ce que les mâchoires présentent une surface latérale sensiblement dans la continuité de la surface latérale antérieure des bras du corps.More specifically, the invention relates to a safety binding heel for a ski boot that can occupy at least two positions, an open position and a closed position in which it is able to securely hold a ski boot for the practice of the ski boot. ski, the heel comprising a body occupying the same position in each of these two positions of the heel, the body comprising a trigger mechanism to allow the release of the shoe by the opening of the heel in case of effort greater than one predetermined threshold, the heelpiece further comprising a lever comprising jaws in its anterior part, adapted to cooperate with the heel of a ski boot, the lever being rotatably mounted relative to the body about an axis so as to occupy two different positions corresponding to the two open and closed positions of the heel, at least one end of the axis of rotation being at the level of the body of the heel, characterized in that the jaws have a lateral surface substantially in continuity with the anterior lateral surface of the arms of the body.

La partie antérieure du corps fixe peut former une fourche et l'axe de rotation du levier peut être directement maintenu au niveau des bras latéraux de la fourche au niveau de ses extrémités.The front part of the fixed body can form a fork and the axis of rotation of the lever can be directly maintained at the side arms of the fork at its ends.

Les deux extrémités de l'axe de rotation du levier peuvent être fixées sur les faces latérales extérieures des bras du corps fixe, par un procédé de type boutrolage.Both ends of the axis of rotation of the lever can be fixed on the outer lateral faces of the arms of the fixed body, by a method of the type of stripping.

Le levier peut présenter une partie traversée par l'axe de rotation, positionnée entre les deux bras latéraux du corps fixe.The lever may have a portion traversed by the axis of rotation, positioned between the two lateral arms of the fixed body.

Selon une variante avantageuse, le levier ne présente pas de surface latérale de faible épaisseur recouvrant latéralement les bras latéraux du corps.According to an advantageous variant, the lever does not have a thin lateral surface laterally covering the lateral arms of the body.

La partie du levier à l'arrière des mâchoires peut se présenter essentiellement dans un volume positionné au-dessus du corps, ne dépassant pas latéralement les plans verticaux délimités par les surfaces latérales extérieures des bras du corps.The portion of the lever at the rear of the jaws may be substantially in a volume positioned above the body, not laterally extending beyond the vertical planes delimited by the outer lateral surfaces of the arms of the body.

Pour cela, la partie du levier à l'arrière des mâchoires peut être délimitée par deux arêtes latérales se rapprochant l'une de l'autre de l'avant vers l'arrière de la talonnière.For this, the portion of the lever at the rear of the jaws may be delimited by two lateral edges approaching one another from the front to the rear of the heel.

L'invention porte aussi sur un procédé de fabrication d'une talonnière de fixation de sécurité pour chaussure de ski telle que définie précédemment, caractérisé en ce qu'il comprend l'étape consistant à maintenir les extrémités de l'axe de rotation directement sur le corps, par exemple par boutrolage.The invention also relates to a method of manufacturing a safety binding heel for a ski boot as defined above, characterized in that it comprises the step of keeping the ends of the axis of rotation directly on the body, for example by extrusion.

Enfin, l'invention porte aussi sur un ski comprenant une talonnière de fixation de sécurité pour chaussure de ski telle que définie précédemment.Finally, the invention also relates to a ski comprising a heel safety fixing for ski boot as defined above.

These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:
  • The figure 1 represents a heel with fixed body according to the prior art;
  • the figure 2 represents a front perspective view of a heel piece according to an embodiment of the invention, in the closed position;

Selon le mode d'exécution de l'invention représenté aux figures 2 à 5, la talonnière comprend un corps fixe 11 incluant le mécanisme de déclenchement, c'est à dire essentiellement le ressort de déclenchement en appui sur une came agissant au niveau de l'axe de rotation 13 de la mâchoire 14, selon un principe connu de l'art antérieur.According to the embodiment of the invention shown in Figures 2 to 5 , the heel comprises a fixed body 11 including the triggering mechanism, that is to say essentially the trigger spring bearing on a cam acting at the axis of rotation 13 of the jaw 14, according to a known principle of the prior art.

Le corps 11 forme dans sa partie antérieure une fourche, comprenant des bras latéraux épais 17, entre lesquels vient se positionner une partie 19 du levier mâchoire 12 et sur lesquels viennent directement se fixer les extrémités de l'axe de rotation 13 du levier mâchoire 12, par exemple par boutrolage sur leur surface latérale extérieure. Ce corps 11 est associé de manière connue à une embase distincte comprenant un logement pour recevoir le frein de la fixation.The body 11 forms in its front part a fork, comprising thick lateral arms 17, between which is positioned a portion 19 of the jaw lever 12 and on which are directly attached the ends of the axis of rotation 13 of the jaw lever 12 for example by stripping on their outer side surface. This body 11 is associated in known manner with a separate base comprising a housing for receiving the brake of the fastener.

Le levier 12 comprend des mâchoires 14 dans sa partie antérieure, dont les dimensions sont normalisées et identiques aux mâchoires de l'art antérieur. Toutefois, le levier ne comprend plus des bras latéraux 6 chevauchant le corps 11 comme dans l'art antérieur. Les mâchoires 14 présentent une surface latérale 16, de petite dimension, sensiblement positionnée dans la continuité des surfaces latérales des bras latéraux 17 du corps 11. Le reste du levier 12 présente une forme relativement plane, étroite et profilée, ses deux arêtes latérales 18 restant positionnées au-dessus du corps 11 et se rapprochant pour converger vers la partie arrière du levier 12, qui comprend une partie 15 adaptée pour l'actionnement du levier 12, pour ouvrir et fermer la talonnière. Pour limiter les risques de contact avec les carres des skis, la partie du levier 12 en arrière des mâchoires 14 est confinée dans un volume étroit au-dessus du corps 11, délimité par les plans latéraux verticaux définis par les surfaces latérales des bras 17 du corps 11 et les surfaces latérales 16 des mâchoires 14. Ces surfaces 16 sont les surfaces du levier mâchoire 12 les plus exposées aux chocs avec les carres des skis. Comme elles présentent globalement une petite surface et qu'elles sont de plus positionnées dans le prolongement des surfaces latérales 17 du corps 11, elles sont sensiblement protégées. Ce mode de réalisation permet de limiter au maximum les risques d'agressions subies par le levier, qui peut ainsi être fabriqué dans un matériau moins résistant que dans l'art antérieur, et dans lequel des ouvertures 20 peuvent être réalisées, pour réduire la quantité de matériau nécessaire tout en offrant un aspect esthétique attrayant.The lever 12 comprises jaws 14 in its front part, whose dimensions are normalized and identical to the jaws of the prior art. However, the lever no longer includes side arms 6 overlapping the body 11 as in the prior art. The jaws 14 have a lateral surface 16, of small size, substantially positioned in the continuity of the side surfaces of the lateral arms 17 of the body 11. The remainder of the lever 12 has a relatively flat, narrow and profiled shape, its two lateral edges 18 remaining positioned above the body 11 and approaching to converge towards the rear part lever 12, which comprises a portion 15 adapted to actuate the lever 12, to open and close the heel. To limit the risk of contact with the edges of the skis, the portion of the lever 12 behind the jaws 14 is confined in a narrow volume above the body 11, delimited by the vertical lateral planes defined by the lateral surfaces of the arms 17 of the body 11 and the side surfaces 16 of the jaws 14. These surfaces 16 are the surfaces of the jaw lever 12 most exposed to impact with the edges of the skis. As they have a small overall surface and they are further positioned in the extension of the side surfaces 17 of the body 11, they are substantially protected. This embodiment makes it possible to limit as much as possible the risks of attack on the lever, which can thus be made of a material that is less resistant than in the prior art, and in which openings 20 can be made, in order to reduce the amount of damage. of necessary material while offering an attractive aesthetic appearance.

La figure 5 illustre une coupe de la talonnière au niveau de l'axe de rotation 13. Les bras 17 du corps 11 occupent les parties latérales et reçoivent directement la fixation de l'axe 13, dont les extrémités sont positionnées au niveau de leurs faces latérales. Le levier 12 présente une partie 19 traversée par l'axe 13, sensiblement au niveau de sa position centrale, entre les deux bras 17 du corps 11. Dans cette variante de réalisation, les efforts subis par le levier 12 lors des mouvements de rotation sont mieux répartis.The figure 5 illustrates a section of the heel at the axis of rotation 13. The arms 17 of the body 11 occupy the side portions and receive directly the attachment of the axis 13, the ends are positioned at their side faces. The lever 12 has a portion 19 traversed by the axis 13, substantially at its central position, between the two arms 17 of the body 11. In this embodiment, the forces experienced by the lever 12 during the rotational movements are better distributed.

L'invention porte aussi sur le procédé de fabrication d'une talonnière à corps fixe de fixation de ski qui comprend l'étape de fixation des extrémités de l'axe de rotation 13 du levier 12 directement sur le corps 11, par exemple par boutrolage sur les surfaces latérales extérieures des bras 17. Ces bras 17 sont épais et résistants et peuvent facilement supporter cette opération, ainsi que d'éventuels futurs chocs reçus par exemple par les carres de ski. En variante, tout autre procédé permettant d'obtenir un maintien en translation de cet axe 13 sur le corps 11 pourrait convenir, par exemple sur la base de l'utilisation de rivets, de vis en appui sur l'axe, ou de serre-clips, voire un simple montage en force de l'axe dans une ouverture de faible diamètre, sachant que les efforts en translation subis par l'axe sont relativement faibles.The invention also relates to the method of manufacturing a heel with fixed ski binding body which comprises the step of fixing the ends of the axis of rotation 13 of the lever 12 directly on the body 11, for example by stripping on the outer side surfaces of the arms 17. These arms 17 are thick and strong and can easily withstand this operation, as well as possible future shocks received for example by the ski edges. As a variant, any other method making it possible to obtain a translation retention of this axis 13 on the body 11 could be suitable, for example on the basis of the use of rivets, of screws resting on the axis, or of clamping clips, or even a simple mounting in force of the axis in a small diameter opening, knowing that the translational forces experienced by the axis are relatively small.

Le mode de réalisation préféré de l'invention a été décrit de manière non limitative en référence aux figures 3 et 4. D'autres variantes de réalisation restant dans le concept de l'invention sont envisageables.The preferred embodiment of the invention has been described in a nonlimiting manner with reference to the figures 3 and 4 . Other embodiments remaining within the concept of the invention are conceivable.

Par exemple, toute solution dans laquelle au moins une extrémité de l'axe 13, de préférence ses deux extrémités, est fixée directement sur le corps fixe 11 et non plus sur le levier 12 permet d'atteindre l'avantage d'une moindre sollicitation du levier 12, quelle que soit la forme de ce levier.For example, any solution in which at least one end of the axis 13, preferably its two ends, is fixed directly on the fixed body 11 and not on the lever 12 makes it possible to achieve the advantage of less stress. lever 12, regardless of the shape of this lever.

Ensuite, une forme du levier 12 dans laquelle les bras latéraux du levier sont totalement supprimés, voire simplement de surface réduite, permet d'atteindre un avantage supplémentaire d'une moins grande vulnérabilité aux chocs lors de la pratique du ski.Then, a form of the lever 12 in which the lateral arms of the lever are completely removed, or even simply reduced surface, allows to achieve an additional advantage of a lower vulnerability to shocks during skiing.

Finalement, l'invention atteint bien les objets recherchés et présente les avantages suivants :

  • l'axe de rotation 13 n'est plus fixé sur les bras du levier 12, ce qui élimine une contrainte subie par le levier et permet de le simplifier et/ou d'utiliser un matériau moins rigide ;
  • l'axe de rotation 13 étant directement boutrolé sur le corps fixe 11, il est aussi fixe, alors que dans les solutions de l'art antérieur, il tournait en accompagnant le mouvement du levier mâchoire 12. L'immobilisation de cet axe induit donc l'avantage supplémentaire de diminuer les sollicitations mécaniques de l'ensemble de la talonnière et donc de restreindre son usure ;
  • selon la variante représentée, le levier 12 ne présente plus de bras latéraux de faible épaisseur et ne subit plus ou beaucoup moins les agressions des carres d'un ski, par rapport à l'art antérieur. Cela confirme encore la possibilité d'utiliser un matériau moins rigide pour cet élément ;
  • cette nouvelle structure de la talonnière permet de réduire la quantité globale de matériau utilisé pour le levier mâchoire 12, ce qui permet, à matériau identique avec l'art antérieur, d'obtenir un levier moins cher ;
  • le volume de la talonnière est restreint, ce qui réduit son encombrement et facilite son intégration sur des skis plus étroits ;
  • le corps 11 de la talonnière subit des nouvelles contraintes, en remplacement du levier 12. Toutefois, comme ces contraintes s'exercent sur des parties épaisses et résistantes, elles n'ont aucune conséquence sur la structure de la talonnière ;
  • enfin, cette solution permet à la talonnière d'atteindre une nouvelle esthétique plus attrayante du fait de la possibilité de donner au levier 12 une forme profilée telle que représentée sur les figures 2 et 3.
Finally, the invention achieves the desired objects and has the following advantages:
  • the axis of rotation 13 is no longer fixed on the arms of the lever 12, which eliminates a stress experienced by the lever and makes it possible to simplify it and / or to use a less rigid material;
  • the axis of rotation 13 is directly buckled on the fixed body 11, it is also fixed, while in the solutions of the prior art, it rotated accompanying the movement of the jaw lever 12. The immobilization of this axis induces the additional advantage of reducing the mechanical stresses of the entire heel and therefore to limit its wear;
  • according to the variant shown, the lever 12 no longer has thin side arms and no longer undergoes or much less aggressions of the edges of a ski, compared to the prior art. This further confirms the possibility of using a less rigid material for this element;
  • this new structure of the heel piece reduces the overall amount of material used for the jaw lever 12, which makes it possible, with identical material with the prior art, to obtain a less expensive lever;
  • the volume of the heel is limited, which reduces its size and facilitates its integration on narrower skis;
  • the body 11 of the heel is subjected to new constraints, replacing the lever 12. However, as these constraints are exerted on thick and resistant parts, they have no effect on the structure of the heel;
  • finally, this solution allows the heel to achieve a new aesthetic more attractive because of the possibility of giving the lever 12 a shaped shape as shown on the Figures 2 and 3 .
