Description

L'invention concerne un élément de retenue de l'avant d'une chaussure sur un ski.The invention relates to a retainer element of the front of a shoe on a ski.

Plus exactement, l'invention concerne un élément de retenue à déclenchement asymétrique, c'est-à-dire dont les paramètres de libération de la chaussure sont différents selon le sens dans lequel la chaussure sollicite la mâchoire de retenue.More specifically, the invention relates to a retainer asymmetrical trigger, that is to say whose parameters of release of the shoe are different according to the meaning wherein the shoe biases the retaining jaw.

De façon connue, un élément de retenue avant comprend une mâchoire de retenue qui est maintenue dans une position centrée sur le ski par un dispositif de rappel élastique. En réponse aux sollicitations exercées par la chaussure, la mâchoire est susceptible de se déplacer latéralement d'un côté ou de l'autre de cette position alignée jusqu'à permettre la libération de la chaussure.In known manner, a front retention element comprises a retainer jaw that is held in a centered position on the ski by an elastic return device. In response the solicitations exerted by the shoe, the jaw is likely to move sideways on one side or the other from this aligned position until allow the release of the shoe.

On sait par ailleurs que le genou d'un skieur peut supporter une sollicitation en torsion de la jambe plus élevée si le pied est entraíné vers l'extérieur, par contre le genou est plus fragile si le pied est entraíné vers l'autre pied. Ces sollicitations en torsion se traduisent par un effort latéral exercé par l'avant de la chaussure sur la mâchoire.We also know that the knee of a skier can withstand torsion stress of the higher leg if the foot is driven outwards, against the knee is more fragile if the foot is driven to the other foot. These Torsional stresses result in lateral effort exercised by the front of the shoe on the jaw.

Pour tenir compte de cela, on a proposé des constructions d'élément de retenue avant à déclenchement asymétrique. De telles constructions ont été divulguées notamment dans les demandes de brevet FR 1 503 847, FR 1 503 848, FR 1 503 849, ou encore EP 785 002, EP 785 003, EP 807 453, EP 807 454.To take account of this, we have proposed constructions front retainer with asymmetrical release. Of Such constructions have been disclosed in particular in patent applications FR 1 503 847, FR 1 503 848, FR 1 503 849, or further EP 785,002, EP 785,003, EP 807,453, EP 807,454.

L'objet de l'invention est de proposer un nouveau mode de construction d'un élément de retenue de l'avant d'une chaussure qui présente un fonctionnement asymétrique en déclenchement latéral.The object of the invention is to propose a new mode of construction of a retainer of the front of a shoe which has asymmetrical operation in tripping lateral.

Ce nouveau mode s'applique à une construction d'élément de retenue avant qui est dit à corps fixe et à ailes indépendantes. Un élément de retenue de ce type est connu de la demande de brevet FR 2 624 387. Globalement, cet élément comprend un corps prévu pour être immobilisé sur le ski dans la direction longitudinale qu'il définit, et deux ailes indépendantes articulées au corps autour d'un axe sensiblement vertical. Chacune des ailes est en prise sur un tirant ou un piston mobile qui agit sur un ressort de rappel.This new mode applies to an element construction of front restraint which is said to have fixed and winged body independent. A restraint of this type is known to the patent application FR 2 624 387. Overall, this element includes a body intended to be immobilized on the ski in the longitudinal direction that it defines, and two wings articulated to the body about an axis substantially vertical. Each wing is engaged on a tie rod or movable piston acting on a return spring.

Un but de l'invention est de proposer une modification simple de cette construction qui rende asymétrique son mode de fonctionnement.An object of the invention is to propose a modification simple of this construction that makes asymmetric its mode of operation.

L'élément de retenue selon l'invention comprend une embase prévue pour être reliée solidairement au ski, surmontée d'un corps, une mâchoire ayant deux ailes de retenue indépendantes articulées au corps autour d'un axe vertical, les ailes ayant au-delà de leur axe d'articulation un bec d'aile exerçant une action par appui sur la tête d'un tirant mobile rappelé par un ressort.The retaining element according to the invention comprises a base intended to be firmly connected to the ski, surmounted by a body, a jaw with two independent wings articulated to the body about a vertical axis, the wings having beyond their axis of articulation a wing beak exerting a action by pressing on the head of a moving tie recalled by a spring.

L'élément est caractérisé par le fait qu'un basculeur articulé par rapport à l'embase est intercalé entre les becs d'aile et la tête du tirant, que les becs d'aile sont en appui contre une branche du basculeur, et que le basculeur est monté de façon asymétrique par rapport à l'embase ou aux becs d'aile.The element is characterized by the fact that a rocker articulated relative to the base is interposed between the nozzles of wing and the head of the tie, that the wingtips are in support against a branch of the rocker, and that the rocker is mounted asymmetrically with respect to the base or the wingtips.

L'idée générale de l'invention est d'intercaler entre les becs d'ailes et le tirant une pièce articulée et de jouer sur les bras de levier avec lesquels cette pièce articulée transmet au tirant les sollicitations qu'elle reçoit de l'un ou l'autre des becs d'ailes.The general idea of the invention is to interpose between wingtips and pulling it an articulated piece and playing on the lever arms with which this articulated piece transmits pulling the solicitations she receives from one or the other wings beaks.

Le document d'art antérieur EP 807 453 décrit un élément avec basculeur intercalé entre les becs d'aile et la tête du tirant, mais ce bardeur est un volet mobile qui n'est pas articulé par rapport à un point fixe de l'embase.The prior art document EP 807 453 describes a rocker element interposed between the wingtips and the head of the tie rod, but this rocker is a movable flap which is not articulated with respect to a fixed point of the base .

L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui lui sont attachés.

    • L'élément de retenue 1 qui est représenté dans la figure 1 comprend une embase 2 surmontée d'un corps 3. L'embase est prévue pour être reliée solidairement au ski par exemple par des vis. Elle est prolongée vers l'arrière par une plaque d'appui 4 prévue pour recevoir la chaussure.The retaining element 1 which is shown in FIG. comprises a base 2 surmounted by a body 3. The base is intended to be connected jointly to the ski for example by screws. It is extended backwards by a plate support 4 provided for receiving the shoe.

    Deux ailes 5 et 6 sont montées sur le corps, elles sont mobiles en rotation autour d'axes 7 et 8 sensiblement verticaux. Les ailes forment la mâchoire de retenue de la chaussure.Two wings 5 and 6 are mounted on the body, they are mobile in rotation about axes 7 and 8 substantially vertical. The wings form the retaining jaw of the shoe.

    Selon le mode de réalisation illustré, les axes des ailes sont en fait portés par une platine 10 rapportée à l'arrière du corps. La platine est en appui contre le reste du corps, et elle est susceptible de basculer vers le haut autour d'un appui supérieur 11, en réponse à une sollicitation verticale vers le haut exercée sur les ailes de la mâchoire.According to the illustrated embodiment, the axes of the wings are in fact carried by a plate 10 attached to the back of the body. The platinum bears against the rest of the body, and she is likely to swing upward around a support upper 11, in response to a vertical bias towards the high exerted on the wings of the jaw.

    Au-delà de leur axe d'articulation, chacune des ailes a un bec, respectivement 13, 14 orienté en direction du plan vertical médian défini par le corps. Les becs sont toutefois distants de ce plan.Beyond their axis of articulation, each of the wings has a beak, respectively 13, 14 oriented towards the plane median vertical defined by the body. The beaks are however distant from this plane.

    Les becs sont en liaison avec la tête 16 d'un tirant 17 logé dans un évidement 18 du corps. Le tirant est mobile dans le plan vertical médian, approximativement selon une direction longitudinale. De préférence, les becs d'ailes sont situés à la hauteur de l'axe du tirant, ou au-dessus.The nozzles are in connection with the head 16 of a tie rod 17 housed in a recess 18 of the body. The pulling is mobile in the median vertical plane, approximately in one direction longitudinal. Preferably, the wingtips are located at the height of the axis of the tie rod, or above.

    Un ressort 19 est monté dans l'évidement 19. Une extrémité du ressort est en appui contre une paroi 20 du corps délimitant l'arrière de l'évidement 19. L'autre extrémité du ressort est retenue par un bouchon 22 vissé à l'extrémité du tirant 17 et guidé dans l'évidement 19 du corps. Le bouchon permet de régler par ailleurs la compression initiale du ressort.A spring 19 is mounted in the recess 19. One end the spring bears against a wall 20 of the delimiting body the back of the recess 19. The other end of the spring is retained by a plug 22 screwed to the end of the tie rod 17 and guided in the recess 19 of the body. The plug allows you to adjust in addition, the initial compression of the spring.

    D'autres modes de montage du tirant et du ressort pourraient également convenir. Other modes of mounting the tie rod and the spring could also be suitable.

    Selon l'invention, un basculeur articulé 24 intervient entre les becs d'aile et la tête du tirant. Le basculeur est articulé à sa base par rapport à l'embase 2 de l'élément autour d'un axe de pivotement 25. Sa branche supérieure 27 est intercalée entre les becs 13 et 14 et la tête du tirant, c'est-à-dire que les becs sont en appui contre la branche supérieure du basculeur, elle-même en appui contre la tête du tirant.According to the invention, an articulated rocker 24 intervenes between the wingtips and the head of the tie rod. The rocker is articulated at its base relative to the base 2 of the element around of a pivot axis 25. Its upper branch 27 is interposed between the beaks 13 and 14 and the head of the tie rod, that is to say that the beaks are in support against the upper branch the rocker, itself in support against the head of the tie rod.

    Comme cela est visible dans la figure 3, par exemple, le basculeur est une pièce en tôle avec une section en forme de "U". L'axe de pivotement est logé à la base du tirant dans les parois latérales 24a et 24b du "U". La paroi de fond 24c a dans sa partie supérieure une découpe 26 prévue pour être traversée par le corps du tirant 17 et pour retenir la tête 16 du tirant.As can be seen in Figure 3, for example, the tilter is a sheet metal part with a section in the form of "U". The pivot axis is housed at the base of the tie rod in the sidewalls 24a and 24b of the "U". The bottom wall 24c has in its upper part a cutout 26 intended to be crossed by the body of the tie rod 17 and to retain the head 16 of the tie rod.

    La figure 4 représente l'élément de retenue vu de dessous et met en évidence le logement 28 prévu pour l'axe de pivotement 25. Le logement, qui retient l'axe selon une direction verticale vers le haut, est par ailleurs prévu pour retenir l'axe 25 avec jeu selon une direction longitudinale.Figure 4 shows the restraint seen from below and highlights housing 28 provided for the axis of pivoting 25. The housing, which retains the axis according to a vertical direction, is also planned for retain the axis 25 with play in a longitudinal direction.

    Une cale 29 contrôle le jeu longitudinal des deux extrémités de l'axe 25 dans son logement.A shim 29 controls the longitudinal play of the two ends of the axis 25 in its housing.

    La cale 29 réduit à un jeu de fonctionnement le jeu d'une extrémité de l'axe 25, et autorise un déplacement longitudinal vers l'arrière de l'autre extrémité. Par exemple comme cela est représenté en figure 5, la cale est réalisée en matière plastique, avec d'un côté un plot 31 dur réalisé dans la masse, et de l'autre un plot 32 rapporté en mousse, en élastomère, viscoélastique, ou tout autre matériau élastiquement déformable. D'autres constructions de la cale pourraient aussi convenir, du moment qu'une extrémité de l'axe 25 est maintenue sans jeu longitudinal dans son logement, et que l'autre extrémité est maintenue avec un jeu libre ou élastique. Avantageusement, la cale 29 est réversible, c'est-à-dire qu'elle peut être assemblée à l'embase de deux façons différentes, avec le plot déformable d'un côté ou de l'autre de l'élément de retenue. Ceci simplifie la construction de l'élément. On pourrait également se passer de la cale et contrôler le déplacement des deux extrémités de l'axe uniquement par les dimensions du logement. Le plot déformable est par ailleurs facultatif, et l'on pourrait laisser libre l'espace du logement où l'extrémité de l'axe est susceptible de se déplacer avec jeu.Wedge 29 reduces to a running game the game of a end of the axis 25, and allows a longitudinal displacement towards the back of the other end. For example as this is represented in FIG. 5, the wedge is made of plastic, with one side a hard pin 31 made in the mass, and on the other a pad 32 reported in foam, elastomer, viscoelastic, or any other elastic material deformable. Other constructions of the hold could also appropriate, as long as one end of axis 25 is maintained without longitudinal play in its accommodation, and that the other end is held with free or elastic play. Advantageously, the wedge 29 is reversible, that is to say that it can be assembled at the base in two ways different, with the deformable pin on one side or the other of the restraining element. This simplifies the construction of item. We could also do without the hold and control the movement of both ends of the axis only by the dimensions of the dwelling. The deformable stud is optional, and we could leave it free housing space where the end of the axis is likely to to move with game

    L'élément de retenue fonctionne de la façon suivante. En l'absence de sollicitation, le tirant plaque le basculeur contre les becs d'aile, et son axe de pivotement 25 en butée par ses deux extrémités contre la partie avant du logement 29.The retainer operates as follows. In the absence of stress, the pulling plate the rocker against the wing tips, and its pivot axis 25 in abutment by its two ends against the front part of the housing 29.

    En se référant à la figure 6, lorsque l'aile 5 située du côté du plot dur 31 s'ouvre, en réaction aux efforts exercés par le bec d'aile 13 et la tête 16 du tirant, le basculeur pivote autour de son axe 25 en prenant appui principalement sur l'extrémité 25b de cet axe. Comme le jeu longitudinal de cette extrémité est réduit au jeu de fonctionnement par le plot dur 31, le basculeur pivote normalement, et la composante longitudinale du mouvement de l'aile est transmise par le basculeur à la tête du tirant.Referring to FIG. 6, when the wing 5 located side of the hard pad 31 opens, in response to exerted efforts by the wingtip 13 and the head 16 of the tie rod, the rocker rotates around its axis 25, relying mainly on the end 25b of this axis. As the longitudinal play of this end is reduced to the operating game by the hard pad 31, the rocker pivots normally, and the component longitudinal movement of the wing is transmitted by the tipper at the head of the tie rod.

    En se référant maintenant à la figure 7, si c'est l'aile 6 qui s'ouvre, l'axe 25 du basculeur prend appui par son extrémité 25a contre le plot déformable 32 qui autorise un déplacement contrôlé de l'extrémité 25a de l'axe. Le basculeur se met alors en travers, comme le montre la figure 7, et démultiplie le déplacement du tirant par rapport au mouvement longitudinal du bec d'aile 14. Dans ces conditions, l'aile 6 est susceptible de s'ouvrir plus facilement que l'aile 5, c'est-à-dire pour une sollicitation d'intensité moindre. De préférence, comme cela est visible dans les figures , le dessous de la tête du tirant est bombé pour faciliter le mouvement de rotation du basculeur par rapport à la tête du tirant.Referring now to Figure 7, if it is Wing 6 which opens, the axis 25 of the rocker is supported by its end 25a against the deformable stud 32 which allows a controlled displacement of the end 25a of the axis. The rocker then gets in the way, as shown in Figure 7, and reduces the movement of the tie rod relative to the movement of the wing nose 14. In these circumstances, the wing 6 is likely to open more easily than wing 5, that is to say for a solicitation of less intensity. Of preferably, as can be seen in the figures, the under the head of the tie is curved to facilitate the rotational movement of the rocker relative to the head of the pulling.

    Il va de soi que pour l'autre élément avant monté sur l'autre ski de la paire, la position relative des plots durs et déformables est inversée pour que les éléments de retenue aient un fonctionnement symétrique l'un par rapport à l'autre.It goes without saying that for the other element before mounted on the other ski of the pair, the relative position of the hard studs and deformable is reversed so that the retaining elements have symmetrical operation with respect to each other.

    Avantageusement, il est possible de construire les deux éléments d'une paire avec les mêmes éléments. Le fonctionnement symétrique peut être en effet obtenu par un simple retournement de la cale 29 qui peut être montée dans deux positions différentes. En outre il est possible de jouer sur la dureté statique et/ou dynamique du plot déformable 32 pour contrôler le mouvement par lequel le plot se met en travers, en vitesse et en amplitude.Advantageously, it is possible to build both elements of a pair with the same elements. Operation symmetric can be indeed obtained by a simple reversal of the wedge 29 which can be mounted in two positions different. In addition it is possible to play on the hardness static and / or dynamic deformable stud 32 to control the movement by which the stud gets across, in speed and in amplitude.

    Les figures 8 à 10 sont relatives à une variante de mise en oeuvre de l'invention.Figures 8 to 10 relate to a variant of implementation of the invention.

    Selon cette variante, on joue sur le bras de levier avec lequel chaque bec d'aile sollicite le basculeur additionnel.According to this variant, we play on the lever arm with which wing nose solicits the additional rocker.

    La figure 8 représente en vue de face un basculeur 34 qui est de même type que le basculeur 24 précédent, sauf pour les différences de construction qui seront décrites ultérieurement. Notamment, le basculeur 34 a deux ailes 34a, 34b, une paroi de fond 34c avec une découpe 26 pour le tirant.FIG. 8 shows a front view of a rocker 34 which is the same type as the previous rocker 24, except for the construction differences that will be described later. In particular, the rocker 34 has two wings 34a, 34b, a wall of bottom 34c with a cutout 26 for the pulling.

    Le basculeur est monté dans l'embase de l'élément de retenue comme le basculeur 24 précédent, par contre, il n'est prévu qu'un jeu de fonctionnement au niveau du logement de l'axe 35.The rocker is mounted in the base of the element of retained as the previous rocker 24, however, it is not expected that a game operating at the housing level of the axis 35.

    Selon le mode de réalisation illustré, à la hauteur des becs d'aile, la paroi de fond a deux bosses 38 et 39 situées à des distances différentes de l'axe 35. Chacune des bosses est prévue pour recevoir l'appui d'un bec d'aile. Ainsi, les bras de levier avec lesquels les ailes sollicitent le basculeur sont différents.According to the illustrated embodiment, at the height of the beaks, the bottom wall has two bumps 38 and 39 located at different distances from the axis 35. Each of the bumps is designed to receive the support of a wing beak. So, the arms lever with which the wings urge the rocker are different.

    La figure 9 représente le bec d'aile 40 en appui contre la bosse 38. De la même façon, la figure 10 représente le bec d'aile 41 en appui contre la bosse 39. Le bras de levier étant supérieur dans ce dernier cas, l'aile associée au bec 41 aura plus de facilité à s'ouvrir que l'autre.FIG. 9 represents the wing nose 40 resting against the In the same way, Figure 10 represents the beak wing 41 against the hump 39. The lever arm being superior in the latter case, the wing associated with the beak 41 will have easier to open than the other.

    Naturellement, le basculeur de l'élément de retenue associé à l'autre ski d'une paire de skis aurait un basculeur avec une position relative des plots inversée. Pour obtenir un fonctionnement symétrique de deux éléments de retenue d'une paire, il est ici nécessaire de construire ces éléments avec des basculeurs différents, l'un prévu pour un élément droit, l'autre pour un élément gauche.Naturally, the rocker of the associated retainer at the other ski a pair of skis would have a rocker with a relative position of the pads reversed. To obtain a symmetrical operation of two retaining elements of a pair, here it is necessary to build these elements with different rockers, one provided for a straight element, the other for a left element.

    La figure 11 illustre une variante de réalisation. Selon cette variante, ce sont les becs d'ailes eux-mêmes qui sont situés à une distance différente de l'axe du basculeur.Figure 11 illustrates an alternative embodiment. according to this variant, these are the wingtips themselves which are located at a different distance from the axis of the rocker.

    Ainsi, cette figure représente un basculeur 44 articulé autour d'un axe 45 et sollicité par deux becs d'aile 47 et 48 qui sont situés à une distance différente par rapport à l'axe 45.Thus, this figure represents an articulated rocker 44 around an axis 45 and biased by two wings 47 and 48 which are located at a different distance from the axis 45.

    Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally, this description is only given indicative, and further developments could be invention without departing from the framework of it.
