Description

L'invention concerne une talonnière de fixation de sécurité 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.The invention relates to a shoe safety attachment heel ski, that is to say a device intended to maintain in a secure manner the back of a shoe on a ski while exerting pressure on the heel the shoe while pressing forward the entire shoe against a front fixing device, and by ensuring automatic from the back of the shoe if the skier falls forward. It also relates to a ski on which is fixed such a heel.

Une talonnière, qui est devenue une image de marque du Demandeur, est par exemple décrite dans les brevets FR2765115 et EP0893146. Une telle talonnière est schématiquement représentée sur la figure 1. Elle se compose d'un corps cylindrique tubulaire 1 comprenant à une extrémité un agrippe talon 2. Ce corps est articulé en rotation autour d'une came 3 formée dans une pièce cylindrique faisant partie d'un étrier en forme de U dont les deux bras 4 sont reliés à une plaque 5 montée pivotante. Cette plaque 5 est en général montée sur une embase elle-même montée sur une glissière relativement large, fixée sur le ski 6, de manière à pouvoir régler la position longitudinale de la fixation. Le corps 1 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, le corps 1 comprend généralement un ressort hélicoïdal, travaillant en compression entre un piston en appui sur la came 3 et une butée située vers l'extrémité opposée à la came. La forme de la came 3 est telle que sous l'effet de pression du ressort, la chaussure 7 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 1 autour de la came 3 en repoussant le piston et en comprimant le ressort, ce qui déclenche l'ouverture de la talonnière. L'avantage d'une telle talonnière du Demandeur vient du fait que la fonction de déclenchement se trouve dans le corps tubulaire 1, par ce biais physiquement séparée des autres fonctions principales de la talonnière, comme la fonction de réglage de sa position longitudinale sur le ski. Cela facilite l'entretien et la réparation de ces talonnières par rapport aux talonnières classiques dans lesquelles toutes les fonctions dont celle de déclenchement sont réunies dans un même corps directement positionné sur le ski. De plus, ce type de déclenchement permet de déclencher la fixation à des efforts très élevés, particulièrement adaptés au ski de compétition, contrairement aux mécanismes classiques mentionnés ci-dessus.A heel, which has become a brand image of the Applicant, is for example described in patents FR2765115 and EP0893146. Such a heel is schematically represented in FIG. composed of a tubular cylindrical body 1 comprising at one end a grasping heel 2. This body is articulated in rotation around a cam 3 formed in a cylindrical part forming part of a U-shaped stirrup whose two arms 4 are connected to a pivotally mounted plate 5. This plate 5 is usually mounted on a base itself mounted on a relatively wide slide, fixed on the ski 6, so as to be able to adjust the longitudinal position of the binding. Body 1 implements the trigger function, which releases the back of the shoe in case of significant effort as is the case in a fall of the skier to forward. For this, the body 1 generally comprises a spring helical, working in compression between a piston resting on the cam 3 and a stop located towards the end opposite the cam. The shape of the cam 3 is such that under the effect of spring pressure, the shoe 7 once pavement is pressed forward against fixing before and towards down against the ski. Only a major effort can rock the body 1 around the cam 3 by pushing the piston and compressing the spring, which triggers the opening of the heel. The advantage of such Applicant's heel comes from the fact that the trigger function is in the tubular body 1, thereby physically separated other main functions of the heel, such as the function of adjusting its longitudinal position on the ski. This facilitates maintenance and repair of these heels compared to conventional heels in which all the functions including that of triggering are met in the same body directly positioned on the ski. In addition, this type of triggering triggers the fixation to very high forces, particularly suited to competitive skiing, unlike classical mechanisms mentioned above.

Toutefois, les talonnières du Demandeur, précédemment décrites, possèdent, du fait de leur complexité, les inconvénients suivants :

  • les bras 4 de l'étrier présentent globalement un écartement important puisqu'ils contournent latéralement la chaussure de ski 7 entre leur liaison à la plaque 5 et celle à la came 3. Cette géométrie entraíne un risque que les parties latérales de la fixation accrochent la neige, principalement lorsque le ski est en virage, et modifient la trajectoire du ski de manière intempestive ;
  • le mécanisme de déclenchement est en porte-à-faux par rapport aux points de solidarisation des bras avec la plaque pivotante et l'embase, ce qui exige des bras épais et rigides pour résister aux efforts importants qu'ils subissent. Ces bras contribuent à une augmentation du poids de l'ensemble de la talonnière ;
  • ces talonnières comprennent plusieurs pièces placées devant l'agrippe talon, ce qui représente un encombrement difficile à gérer pour permettre le positionnement de la chaussure de ski dont la forme et les dimensions sont normalisées et ne sont pas modifiables ;
  • elles sont coûteuses.
L'homme du métier a envisagé de nombreux aspects de sécurité lorsqu'il a mis au point ces fixations et a proposé une solution complexe composée de nombreuses fonctions mécaniques, permettant effectivement de traiter efficacement certains problèmes de sécurité, mais qui dans le même temps ajoute les nouveaux inconvénients, listés ci-dessus.However, the heels of the Applicant, previously described, have, because of their complexity, the following disadvantages:
  • the arms 4 of the caliper generally have a large spacing since they laterally bypass the ski boot 7 between their connection to the plate 5 and that to the cam 3. This geometry entails a risk that the lateral parts of the binding hang on snow, mainly when the ski is in a bend, and modifies the path of the ski in an untimely manner;
  • the triggering mechanism is cantilevered with respect to the points of attachment of the arms with the pivot plate and the base, which requires thick and rigid arms to withstand the significant efforts they undergo. These arms contribute to an increase in the weight of the entire heel piece;
  • these heels include several pieces placed in front of the heel gripper, which is a space difficult to manage to allow the positioning of the ski boot whose shape and dimensions are standardized and are not modifiable;
  • they are expensive.
The skilled person has considered many aspects of safety when he developed these bindings and proposed a complex solution composed of many mechanical functions, effectively to effectively deal with some security problems, but at the same time adds the new disadvantages, listed above.

L'objet de la présente invention est de proposer une talonnière simplifiée de fixation de sécurité pour chaussure de ski conservant les avantages mentionnés ci-dessus de la solution du Demandeur mais n'en possédant pas les inconvénients.The object of the present invention is to provide a simplified heel safety binding for ski boots retaining the benefits mentioned above of the Applicant's solution but not possessing not the disadvantages.

Plus précisément, un premier objet de l'invention consiste à proposer une talonnière qui différencie physiquement la fonction de déclenchement des autres fonctions.More specifically, a first object of the invention consists in proposing a heel that physically differentiates the triggering function of other functions.

Un second objet de l'invention consiste à proposer une talonnière avec un faible encombrement latéral pour éliminer le risque d'accrocher la neige.A second object of the invention is to propose a heel piece with a Small lateral footprint to eliminate the risk of hanging snow.

Un troisième objet de l'invention consiste à proposer une talonnière libérant au maximum l'espace devant l'agrippe talon afin d'optimiser le positionnement de la chaussure.A third object of the invention is to propose a heel freeing up the space in front of the heel grip to optimize the positioning of the shoe.

Un quatrième objet de l'invention consiste à proposer une talonnière simple, d'un faible poids et peu coûteuse.A fourth object of the invention consists in proposing a heel simple, low weight and inexpensive.

L'invention atteint les objets ci-dessus en proposant une talonnière de fixation de sécurité pour chaussure de ski comprenant un corps tubulaire possédant une fonction de déclenchement et comportant à une de ses extrémités un agrippe talon destiné à maintenir le talon d'une chaussure de ski sur un ski, ce corps tubulaire étant articulé en rotation autour d'une came formée dans une pièce cylindrique, cette came étant solidaire de deux bras latéraux reliés à une embase montée mobile longitudinalement sur un socle destiné à être fixé sur un ski, l'écartement des deux bras au niveau de l'embase étant inférieur à leur écartement au niveau de leur liaison avec la came.The invention achieves the above objects by providing a heel of safety binding for a ski boot comprising a tubular body having a trigger function and having at one of its ends a heel grip intended to hold the heel of a shoe on a ski, this tubular body being articulated in rotation around a cam formed in a cylindrical part, this cam being integral with two lateral arms connected to a base mounted longitudinally movable on a base intended to be fixed on a ski, the spacing of the two arms level of the base being lower than their spacing at their connection with the cam.

Les bras peuvent présenter une forme en V dans une projection sur un plan transversal et leur écartement au niveau de leur liaison avec l'embase peut être sensiblement la moitié de l'écartement maximal des bras au niveau de leur liaison avec la came.The arms can have a V shape in a projection on a transversal plane and their spacing at the level of their connection with the base may be substantially half of the maximum spacing of the arm at their link with the cam.

D'autre part, les bras peuvent présenter une inclinaison vers l'arrière, cette inclinaison vers l'arrière des bras pouvant être de l'ordre de 60 degrés par rapport au plan du socle.On the other hand, the arms may have a backward inclination, this backwards inclination of the arms, which can be of the order of 60 degrees compared to the floor plan.

Les bras peuvent être métalliques et reliés à l'embase par une liaison rivetée par au moins deux axes de solidarisation traversant transversalement l'embase ou à l'aide d'au moins deux vis traversantes. L'axe de la came et le premier axe de solidarisation sont sensiblement dans un même plan vertical.The arms can be metallic and connected to the base by a connection riveted by at least two crossing pins transversely the base or using at least two through screws. The axis of the cam and the first axis of attachment are substantially in the same vertical plane.

En variante, les bras et l'embase forment une seule pièce en matière synthétique et un insert en métal entoure au moins partiellement la came de manière à renforcer la talonnière.In a variant, the arms and the base form a single piece of material synthetic and a metal insert at least partially surrounds the cam in order to strengthen the heel.

La longueur avant de la partie du socle dépassant de l'agrippe talon est courte, la hauteur de la came par rapport au socle est réduite à une hauteur sensiblement proche de la hauteur du talon d'une chaussure de ski.The front length of the part of the pedestal protruding from the heel grip is short, the height of the cam relative to the base is reduced to one height substantially close to the height of the heel of a shoe of ski.

L'invention concerne aussi un ski équipé d'une telle talonnière de fixation de sécurité pour chaussure de ski. The invention also relates to a ski equipped with such a binding heel security for ski boots.

    En référence aux figures 2 à 6, la talonnière selon un mode d'exécution comprend un corps tubulaire 1 similaire à celui de l'art antérieur décrit en référence à la figure 1. Ce corps 1 est articulé autour d'une came 3, formée dans une pièce cylindrique, afin de positionner l'agrippe talon 2 sur le talon d'une chaussure de ski 7 en position fermée. Deux bras 4 sont fixés d'une part aux bords latéraux de la came 3 et d'autre part à une embase 8, elle-même montée sur un socle 9 de manière mobile selon une direction longitudinale à l'aide d'une liaison à glissières 10. Le maintien et la mise en mouvement longitudinal de l'embase 8 sur le socle 9 sont réalisés par des moyens connus de l'art antérieur, non représentés. Le socle 9 est destiné à être fixé sur un ski. With reference to FIGS. 2 to 6, the heel piece according to an embodiment comprises a tubular body 1 similar to that of the prior art described in This body 1 is articulated around a cam 3, formed in a cylindrical piece, in order to position the heel grip 2 on the heel of a ski boot 7 in the closed position. Two arms 4 are attached on the one hand to the lateral edges of the cam 3 and on the other hand to a base 8, itself mounted on a base 9 in a movable manner according to a longitudinal direction by means of a sliding link. the longitudinal movement of the base 8 on the base 9 are made by means known from the prior art, not shown. The base 9 is intended to be fixed on a ski.

    La talonnière sépare totalement la fonction de déclenchement, contenue dans le corps 1, de la fonction de réglage longitudinal de la fixation, réalisée par la liaison entre l'embase 8 et le socle 9. De plus, elle utilise la technologie de déclenchement adaptée au ski de compétition.The heel separates completely the trigger function, contained in the body 1, of the longitudinal adjustment function of the fastener, made by the connection between the base 8 and the base 9. In addition, it uses the Trigger technology adapted to ski racing.

    L'espace à l'avant de l'agrippe talon 2 est entièrement libéré. Il ne reste plus que le socle. L'épaisseur de l'avant de la fixation et la longueur du socle sont ainsi réduites. Cela permet un positionnement de la semelle de la chaussure au plus bas, sans subir de gêne puisque l'encombrement est réduit, plus facile même lorsqu'il y a de la neige collée sous la chaussure par exemple. De plus, la hauteur des bras est réduite à une hauteur sensiblement égale à celle du talon de la chaussure.The space at the front of the heel grip 2 is fully released. It remains more than the base. The thickness of the front of the binding and the length of the base are reduced. This allows a positioning of the sole of the shoe at the lowest, without being inconvenienced because the clutter is reduced, easier even when there is snow stuck under the shoe for example. In addition, the height of the arms is reduced to a height substantially equal to that of the heel of the shoe.

    Les bras 4 présentent à leur base, au niveau de leur liaison avec l'embase 8, un écartement inférieur à leur écartement se trouvant au niveau de leur liaison avec la came, allant même jusqu'à sensiblement la moitié de cet écartement maximal. Ainsi, ces bras ne présentent plus les inconvénients de risquer de frotter sur la neige. Comme il apparaít sur les figures 3 et 4, ils présentent une forme en V dans une projection sur un plan transversal, contrairement aux formes habituelles en U. D'autre part, cette forme a pour autre avantage de permettre l'utilisation de glissières étroites, ce qui participe d'autant plus à la réduction d'ensemble de l'encombrement latéral de la talonnière.The arms 4 have at their base, at their connection with the base 8, a spacing smaller than their spacing being at their level. connection with the cam, even up to substantially half of this maximum spacing. Thus, these arms no longer have the disadvantages to risk rubbing on the snow. As it appears in FIGS. 3 and 4, they have a V shape in a projection on a transverse plane, contrary to the usual forms in U. On the other hand, this form has for another benefit of allowing the use of narrow slides, which participates even more in the overall reduction of congestion lateral of the heel.

    Les bras 4 sont métalliques et fixés à l'embase 8 par une liaison rivetée par trois axes de solidarisation traversant transversalement l'embase 8. En variante, les bras 4 peuvent être fixés sur l'embase 8 à l'aide de trois vis traversantes. Ils sont de plus inclinés vers l'arrière. En effet, leur base se trouve reculée de manière significative par rapport à leur partie supérieure : la pente vers l'arrière est de l'ordre de 60 degrés par rapport au socle dans ce mode d'exécution (voir figure 6). Cette géométrie permet un quasi-alignement dans un même plan vertical de la came 3 et du premier axe de solidarisation 11, ce qui diminue de manière significative le porte-à-faux du mécanisme de déclenchement par rapport aux points de liaison des bras 4 avec l'embase 8. Ces bras, subissant moins d'effort que ceux de l'art antérieur, sont allégés.The arms 4 are metallic and fixed to the base 8 by a riveted connection by three solidarity axes transversely crossing the base 8. In variant, the arms 4 can be fixed on the base 8 with three screws therethrough. They are further inclined to the rear. Indeed, their base is found significantly backward from their upper : the slope towards the back is of the order of 60 degrees compared to the base in this embodiment (see Figure 6). This geometry allows a quasi-alignment in the same vertical plane of the cam 3 and the first fastening axis 11, which significantly reduces the cantilever the trigger mechanism with respect to the connection points 4 arms with the base 8. These arms, undergoing less effort than those of the prior art, are lightened.

    Selon une variante d'exécution encore plus économique, les bras 4 forment une seule pièce avec l'embase 8 et l'ensemble est en matière synthétique. L'articulation du corps 1 autour de l'axe d'articulation de la came 3 est renforcée à l'aide d'une partie métallique insérée au moins partiellement autour de la came 3.According to an even more economical variant of execution, the arms 4 form a single piece with the base 8 and the assembly is made of synthetic. The articulation of the body 1 around the axis of articulation of the cam 3 is reinforced with at least one inserted metal part partially around the cam 3.

    La talonnière selon le mode d'exécution facilite aussi grandement le chaussage de la chaussure de ski, qui peut être réalisé directement en appuyant le talon sur l'agrippe talon 2 en position ouverte, selon une technique communément appelée "step in". Pour cela, le talon est d'abord positionné sur l'agrippe talon 2 de la talonnière en position ouverte de la manière représentée sur la figure 5. Une pression sur le talon va permettre le chaussage de la chaussure afin d'arriver à la position fermée de la talonnière, telle que représentée sur la figure 6. Durant cette phase de chaussage, le talon effectue un arc de cercle représenté sur la figure 5, restant ainsi proche des bras 4 tout au long du chaussage.The heel according to the mode of execution also greatly facilitates the boot of the ski boot, which can be made directly pressing the heel on the heel gripper 2 in the open position, according to a technique commonly called "step in". For that, the heel is first positioned on the heel grip 2 of the heel in the open position of the as shown in Figure 5. Pressure on the heel is allow the boot of the shoe to arrive at the closed position of the heel, as shown in Figure 6. During this phase the heel forms an arc represented in FIG. 5, thus remaining close to the arms 4 throughout the boot.
