Abstract

The ski boot binding has front and rear bindings (3,4) each with a jaw (6,10) to engage the ends of a boot, a housing (7) and a slide (32). Each binding housing has a connecting linkage. Each binding housing is freely slidable along the slide and the two free ends of the connecting linkages are connected by a return spring (39) assembly to oppose a relative outward movement of the bindings.

Description

L'invention concerne un ensemble de retenue d'une chaussure de ski sur un ski, notamment un ski alpin.The invention relates to an assembly for retaining a ski boot on a ski, including alpine skiing.

De façon usuelle une chaussure est retenue sur un tel ski par deux éléments de retenue avant et arrière qui agrippent de façon libérable les embouts avant et arrière de la chaussure.Usually a shoe is retained on such a ski by two retaining elements front and rear which releasably grip the front and rear end pieces of the shoe.

Pour permettre l'adaptation de l'ensemble de retenue à la longueur de la chaussure, l'un au moins des éléments de retenue est mobile le long d'une glissière, et sa position le long de la glissière peut être ajustée à l'aide d'un verrou qui coopère avec une série de crans de la glissière, ou un autre dispositif du même genre. En général cette fonction est remplie par l'élément de retenue arrière.To allow the adaptation of the restraint to the length of the shoe, one at least one of the retaining elements is movable along a slide, and its position along the slide can be adjusted using a lock which cooperates with a series of notches of the slide, or other similar device. In general this function is fulfilled by the rear retainer.

De plus, pour assurer le pincement de la chaussure et permettre au ski de fléchir sans contrainte excessive de la part de la chaussure, l'élément de retenue arrière peut encore reculer depuis sa position fixée par le verrou contre la force de rappel d'un ressort qui est appelé ressort de recul. En flexion de ski, le ski forme un arc, la chaussure qui est considérée comme incompressible forme la corde de l'arc. Il est donc nécessaire que le corps de l'un des éléments de retenue puisse reculer pour permettre au ski de fléchir dans de bonnes conditions. Habituellement le ressort de recul est logé dans le corps de l'élément de retenue arrière, et c'est le corps de l'élément de retenue arrière qui se déplace lors d'un mouvement de recul.In addition, to ensure the pinch of the boot and allow the ski to flex without excessive strain on the shoe, the rear retainer may still back from its position fixed by the latch against the return force of a spring which is called recoil spring. In ski flexion, the ski forms an arc, the shoe which is considered as incompressible forms the bowstring. It is therefore necessary that the body of one of the retainers can move back to allow the ski to flex in good conditions. Usually the recoil spring is housed in the body of the retainer rear, and it is the body of the rear retainer that moves during a movement of decline.

La demande de brevet WO 82/03182 décrit un ensemble de retenue où les éléments de retenue avant et arrière sont montés de façon coulissante chacun dans une glissière solidarisée au ski.Patent application WO 82/03182 describes a retaining assembly where the elements of front and rear retainers are slidably mounted each in a slide united to skiing.

Une bande inextensible relie les deux éléments et définit leur écartement. L'élément avant est immobilisé relativement au ski alors que l'élément arrière est libre de coulisser dans sa glissière tout en étant retenu par la bande inextensible et en étant rappelé élastiquement repoussé par le ressort de recul qui est logé dans le corps.An inextensible strip connects the two elements and defines their spacing. The element front is immobilized relative to the ski while the rear element is free to slide in its slide while being retained by the inextensible band and being recalled elastically pushed back by the recoil spring which is housed in the body.

Un tel dispositif est avantageux dans la mesure où l'effort de réaction qui est généré par la poussée du ressort de recul est renvoyée vers l'élément de retenue avant sans transiter par le ski. La flexion du ski est donc moins perturbée par la poussée du ressort de recul. Il arrive cependant qu'en cas de forte flexion du ski un frottement intense se produise entre le corps et sa glissière, ce qui renvoie des contraintes dans le ski.Such a device is advantageous insofar as the reaction force which is generated by the thrust of the recoil spring is returned to the front retaining element without passing through ski. The flexing of the ski is therefore less disturbed by the thrust of the recoil spring. He is coming however in the event of strong bending of the ski an intense friction occurs between the body and its slide, which returns constraints in skiing.

On connaít par ailleurs d'après la demande de brevet DE 22 46 668 la construction d'un ensemble de retenue où le déplacement des deux éléments est réalisé de façon coordonnée au moyen d'une roue dentée qui coopère avec deux crémaillères reliées au corps de chacun des éléments de retenue.We also know from patent application DE 22 46 668 the construction of a restraint system where the displacement of the two elements is carried out in a coordinated manner by means of a toothed wheel which cooperates with two racks connected to the body of each of the retainers.

Comme dans le cas précédent, les deux crémaillères assurent une reprise des efforts générés par le ressort de recul. As in the previous case, the two racks ensure a recovery of efforts generated by the recoil spring.

Dans les deux cas, tout le mouvement de recul se trouve concentré sur le corps de l'élément arrière, et le ressort de recul agit uniquement sur l'élément de retenue arrière. Les efforts résultant de la poussée de recul se trouvent de ce fait concentrés sur la partie arrière de l'élément de retenue.In both cases, the entire backward movement is concentrated on the body of the rear element, and the recoil spring acts only on the rear retaining element. The forces resulting from the recoil thrust are therefore concentrated on the rear part of the retainer.

Un but de l'invention est de proposer un autre mode de construction d'un ensemble de retenue qui procure une meilleure répartition des efforts de recul.An object of the invention is to propose another mode of construction of a set of restraint which provides a better distribution of recoil forces.

L'ensemble de retenue selon l'invention comprend deux éléments de retenue avant et arrière chacun comprenant une mâchoire de retenue d'une extrémité de la chaussure, un corps portant la mâchoire et une glissière prévue pour être assemblée au ski le long de laquelle le corps est monté de façon coulissante, une tringle de liaison reliée à chacun des corps, chacune des tringles de liaison étant dirigées l'une en direction de l'autre et ayant une extrémité libre à l'opposé du corps auquel elles sont reliées respectivement.The restraint system according to the invention comprises two front retaining elements and rear each comprising a jaw retaining one end of the shoe, a body carrying the jaw and a slide intended to be assembled to the ski along which the body is slidably mounted, a connecting rod connected to each of the bodies, each of the connecting rods being directed one towards the other and having a free end opposite the body to which they are connected respectively.

L'ensemble est caractérisé par le fait que chacun des corps est monté librement coulissant le long de sa glissière et que les deux extrémités libres des tringles de liaison sont reliées par mécanisme à au moins un ressort monté de façon à opposer une résistance élastique à un écartement relatif des deux corps.The assembly is characterized by the fact that each of the bodies is mounted freely sliding along its slide and that the two free ends of the connecting rods are mechanically connected to at least one spring mounted so as to provide resistance elastic to a relative spacing of the two bodies.

    • L'ensemble de retenue comprend des éléments 3 et 4 de retenue des extrémités avant et arrière d'une chaussure.The restraint assembly includes elements 3 and 4 for retaining the front ends and back of a shoe.

    L'élément avant est de tout type approprié. Selon le mode de réalisation illustré l'élément avant 3 a une mâchoire 6 portée par un corps 7. La mâchoire est prévue pour retenir l'embout avant de la chaussure, elle est mobile relativement au corps de part et d'autre de sa position centrée sur l'axe longitudinal du ski, et elle est rappelée dans cette position centrée par un ressort logé dans le corps. Sur l'arrière, une plaque d'appui 8 reliée au corps est prévue pour recevoir la semelle de chaussure.The front element is of any suitable type. According to the illustrated embodiment the front element 3 has a jaw 6 carried by a body 7. The jaw is designed to retain the front toe of the shoe, it is movable relative to the body on either side of its position centered on the longitudinal axis of the ski, and it is recalled in this centered position by a spring housed in the body. On the rear, a support plate 8 connected to the body is provided to receive the shoe sole.

    D'autres types de construction pourraient aussi convenir, notamment la mâchoire pourrait être mobile avec son corps par rapport à un pivot porté par un socle.Other types of construction could also be suitable, in particular the jaw could be movable with its body relative to a pivot carried by a base.

    L'élément arrière 4 comprend également une mâchoire 10 de retenue de l'extrémité arrière de la chaussure. La mâchoire est mobile par rapport à un corps 11 autour d'un axe transversal 12 et elle est rappelée en position de retenue par un ressort logé dans le corps.The rear element 4 also comprises a jaw 10 for retaining the end back of the shoe. The jaw is movable relative to a body 11 around an axis transverse 12 and it is returned to the retaining position by a spring housed in the body.

    Un levier 13 permet de forcer l'ouverture de la mâchoire pour libérer la chaussure de façon volontaire.A lever 13 makes it possible to force the jaw to open to release the shoe from voluntarily.

    En avant de la mâchoire, l'élément arrière a une plaque d'appui 14 prévue pour recevoir la semelle de chaussure, et un dispositif de freinage 15.In front of the jaw, the rear element has a support plate 14 designed to receive the shoe sole, and a braking device 15.

    D'autres constructions pourraient également convenir.Other constructions could also be suitable.

    Selon l'invention, les éléments 3 et 4 sont reliés entre eux par une liaison élastiquement extensible dans le but d'assurer un pincement de la chaussure et de faciliter la flexion du ski dans sa partie centrale.According to the invention, the elements 3 and 4 are interconnected by an elastically bond stretchable in order to ensure a pinch of the boot and to facilitate the flexing of the ski in its central part.

    Selon le mode de réalisation illustré, le corps 7 de l'élément avant 3 est monté librement coulissant dans une glissière 16 reliée solidairement au ski 1 par tout moyen approprié par exemple des vis, par un collage ou un soudage.According to the illustrated embodiment, the body 7 of the front element 3 is mounted freely sliding in a slide 16 connected integrally to the ski 1 by any means suitable for example screws, gluing or welding.

    Une tringle avant 17 est fixée solidairement au corps 7 par l'une de ses extrémités et s'étend en direction de l'autre élément de retenue. La tringle avant est solidaire du corps 7 dans son mouvement de translation longitudinal.A front rod 17 is fixed integrally to the body 7 by one of its ends and extends toward the other retainer. The front rod is secured to the body 7 in its longitudinal translational movement.

    De préférence, ainsi que cela est représenté, la position longitudinale du corps le long de la tringle avant 17 peut être ajustée.Preferably, as shown, the longitudinal position of the body along of the front rod 17 can be adjusted.

    Par exemple comme cela est visible dans la figure 2, la glissière comprend deux rails de glissière 16a, 16b, chacun fixé solidairement au ski. La tringle a une section rectangulaire dont la hauteur correspond à l'épaisseur de la partie inférieure des rails, et dont la largeur est sensiblement égale à l'écartement des rails. Ainsi, les deux rails laissent entre eux un espace qui forme une rainure de guidage pour la tringle 17. De préférence une plaquette de glissement 18 est interposée entre les rails et au moins la tringle pour faciliter son libre glissement.For example, as can be seen in figure 2, the slide includes two rails slide 16a, 16b, each fixed integrally to the ski. The rod has a rectangular section whose height corresponds to the thickness of the lower part of the rails, and whose width is substantially equal to the spacing of the rails. So the two rails leave a space between them which forms a guide groove for the rod 17. Preferably a plate sliding 18 is interposed between the rails and at least the rod to facilitate its free sliding.

    Les rails 16a et 16b ont chacun une section en "C" dont les ouvertures sont en vis-à-vis, et le corps 7 a à sa base deux patins latéraux 20a et 20b en saillie qui sont engagés dans les rails 16a et 16b. De cette façon le corps 7 peut coulisser librement avec la tringle 17 dans la glissière 16.The rails 16a and 16b each have a "C" section, the openings of which face each other, and the body 7 has at its base two projecting side shoes 20a and 20b which are engaged in rails 16a and 16b. In this way the body 7 can slide freely with the rod 17 in slide 16.

    Sous le corps 7, la tringle 17 présente une série de crans espacés selon une direction longitudinale. Seuls les crans 21a et 21b qui sont dans le plan de la figure 2 sont visibles. Under the body 7, the rod 17 has a series of notches spaced in a direction longitudinal. Only the notches 21a and 21b which are in the plane of Figure 2 are visible.

    Un verrou 25 est logé dans le corps 7, le verrou porte à sa base des dents comme les dents 26a et 26b représentées dans la figure 2. Le verrou est mobile autour d'un axe 28 par une action sur sa palette de manoeuvre 29 entre une position basse où au moins une dent est en prise avec un cran de la glissière, et une position haute où les dents sont dégagées de la tringle. Le verrou est représenté en pointillés dans cette dernière position haute. De préférence un ressort non représenté rappelle élastiquement le verrou dans sa position basse.A lock 25 is housed in the body 7, the lock carries teeth at its base like the teeth 26a and 26b shown in Figure 2. The lock is movable around an axis 28 by an action on its operating pallet 29 between a low position where at least one tooth is engaged with a notch of the slide, and a high position where the teeth are released from the rod. The lock is shown in dotted lines in this last high position. Of preferably a spring (not shown) resiliently recalls the lock in its low position.

    Selon le mode de réalisation illustré, l'axe 28 est orienté longitudinalement, et la palette 29 est accessible sur le côté du corps, en avant de la plaque d'appui 8.According to the illustrated embodiment, the axis 28 is oriented longitudinally, and the pallet 29 is accessible on the side of the body, in front of the support plate 8.

    Ceci n'est pas limitatif et d'autres modes de construction pourraient aussi convenir.This is not limiting and other modes of construction could also be suitable.

    D'autres modes de liaison du corps et de la tringle pourraient également être utilisés. Notamment, la position du corps 7 pourrait être ajustée à l'aide d'une vis micrométrique dont le filetage serait en prise avec une succession de crans de la tringle.Other methods of connecting the body and the rod could also be used. In particular, the position of the body 7 could be adjusted using a micrometric screw, the thread would be engaged with a succession of notches of the rod.

    L'élément de retenue arrière présente de la même façon une tringle arrière 31 qui est reliée solidairement au corps 11. Le corps et sa tringle sont libres de coulisser dans une glissière 32.The rear retaining element likewise has a rear rod 31 which is solidly connected to the body 11. The body and its rod are free to slide in a slide 32.

    Le mode de construction est le même que celui de la partie avant, il ne sera donc pas décrit en détails.The construction method is the same as that of the front part, so it will not be described in detail.

    La glissière 32 a deux rails 32a, 32b de guidage des patins latéraux 33a, 33b du corps, et un verrou 35 permet d'ajuster la position longitudinale du corps le long de la tringle.The slide 32 has two rails 32a, 32b for guiding the lateral runners 33a, 33b of the body, and a latch 35 makes it possible to adjust the longitudinal position of the body along the rod.

    Les deux tringles 17 et 31 convergent l'une vers l'autre. Leur extrémité libre pénètre dans un boítier central 36 qui est fixé solidairement au ski par tout moyen approprié, notamment par des vis, par collage ou soudage.The two rods 17 and 31 converge towards each other. Their free end penetrates in a central box 36 which is fixed integrally to the ski by any suitable means, in particular by screws, by gluing or welding.

    Selon le mode de réalisation illustré, le boítier 36 est situé vers le milieu des deux éléments de retenue, c'est-à-dire vers le repère de milieu de chaussure que le ski porte de façon usuelle.According to the illustrated embodiment, the housing 36 is located towards the middle of the two retaining elements, that is to say towards the mid-shoe mark that the ski wears usual way.

    Le boítier renferme un mécanisme de rappel à ressort dont la fonction est d'opposer une force de rappel élastique à un éloignement relatif des corps avant et arrière lors de l'engagement de la chaussure et au cours de la pratique du ski, étant entendu que les deux corps peuvent ici se déplacer.The housing contains a spring return mechanism whose function is to oppose an elastic restoring force at a relative distance from the front and rear bodies during the engagement of the shoe and during skiing, it being understood that the two bodies can move here.

    Selon un premier mode de mise en oeuvre de l'invention illustré dans les figures 4 à 6, les tringles 17 et 31 ont à leur extrémité un repli vers le haut 17a, 31a. Dans la position de repos illustrée en figure 4, c'est-à-dire en l'absence de chaussure, les replis sont dos à dos. Des ressorts 39 et 40 sont placés entre chacun des replis et la paroi du boítier. Ainsi, chacun des ressorts 39 et 40 exerce sur un repli 17a, 3 la une force de rappel élastique qui tend à s'opposer à un éloignement relatif des éléments.According to a first embodiment of the invention illustrated in FIGS. 4 to 6, the rods 17 and 31 have at their end an upward fold 17a, 31a. In the position of rest illustrated in Figure 4, that is to say in the absence of shoes, the folds are back to back. Springs 39 and 40 are placed between each of the folds and the wall of the housing. So everyone springs 39 and 40 exert on a fold 17a, 3 la an elastic restoring force which tends to oppose a relative distance from the elements.

    Chaque ressort s'appuie contre une paroi du boítier, c'est-à-dire sur un élément fixe sur le ski. De cette façon la force de rappel qu'il exerce dépend seulement de sa raideur et de sa compression propres. Each spring rests against a wall of the housing, that is to say on a fixed element on ski. In this way the restoring force which it exerts depends only on its stiffness and its own compression.

    Les ressorts représentés sont des ressorts de compression, mais on pourrait utiliser également des ressorts de traction, ou une combinaison de ressorts de compression et de traction ou tout autre moyen de rappel élastique.The springs shown are compression springs, but one could use also tension springs, or a combination of compression springs and traction or any other elastic return means.

    Au repos les ressorts 39 et 40 sont de préférence précontraints pour que les deux replis soient en appui l'un contre l'autre.At rest the springs 39 and 40 are preferably prestressed so that the two folds are resting against each other.

    En service, comme le montre la figure 5, les deux replis s'écartent l'un de l'autre, provoquant la compression de leur ressort respectif. La position des éléments de retenue après engagement de la chaussure est définie par l'équilibre de poussée entre les deux ressorts 39 et 40.In service, as shown in Figure 5, the two folds deviate from each other, causing the compression of their respective spring. Position of retainers after engagement of the shoe is defined by the balance of thrust between the two springs 39 and 40.

    La figure 6 illustre le fait que chacun des ressorts 39, 40 peut être en fait une batterie de ressorts élémentaires 39a, 39b, 39c, 40a, 40b, 40c. Le nombre et la disposition des ressorts élémentaires ne sont pas limitatifs.FIG. 6 illustrates the fact that each of the springs 39, 40 can in fact be a battery elementary springs 39a, 39b, 39c, 40a, 40b, 40c. The number and arrangement of springs elementary are not limiting.

    Ainsi à l'engagement de la chaussure et au cours de la pratique du ski les deux éléments de retenue sont rappelés l'un vers l'autre par le mécanisme à ressort logé dans le boítier 36. Contrairement aux systèmes usuels l'élément arrière n'a pas de dispositif de recul qui lui est propre. La construction du corps de l'élément arrière est donc simplifiée. De plus le corps peut être plus compact selon une direction longitudinale, ce qui facilite son coulissement dans la glissière.Thus, when the shoe is engaged and during skiing, both retaining elements are returned to each other by the spring mechanism housed in the case 36. Unlike the usual systems, the rear element does not have a reversing device its own. The construction of the body of the rear element is therefore simplified. Moreover the body can be more compact in a longitudinal direction, which facilitates its sliding in the slide.

    Les efforts de pincement de la chaussure et les déplacements des éléments de retenue sont ici partagés entre les éléments avant et arrière. La réaction aux efforts de pincement est ramenée au boítier qui se trouve situé vers le milieu de la chaussure. De ce fait ils sont recentrés par rapport à l'ensemble de retenue. Ces efforts ne sont pas transmis au ski. Au cas où le frottement d'un corps dans sa glissière deviendrait important par exemple à cause de la flexion du ski, l'autre élément peut se substituer à cet élément en se déplaçant de façon additionnelle.Pinch forces of the shoe and displacements of the retaining elements are shared here between the front and rear elements. The reaction to pinch forces is brought back to the case which is located towards the middle of the shoe. Therefore they are refocused with respect to the restraint system. These efforts are not transmitted to the ski. In case where the friction of a body in its slide would become important for example because of the bending of the ski, the other element can replace this element by moving so additional.

    Selon la variante de mise en oeuvre illustrée en figure 7 les ressorts 43 et 44 de rappel des tringles 45 et 46 ont des raideurs différentes.According to the implementation variant illustrated in FIG. 7, the return springs 43 and 44 rods 45 and 46 have different stiffnesses.

    De façon théorique l'effort de pincement exercé sur les deux éléments de retenue reste équilibrée par définition, mais c'est le déplacement de chacun des corps qui est différent. Ceci permet donc de différencier l'un des éléments par un déplacement plus important.Theoretically, the pinching force exerted on the two retaining elements remains balanced by definition, but it is the displacement of each of the bodies that is different. This therefore makes it possible to differentiate one of the elements by a greater displacement.

    Pour donner aux ressorts 43 et 44 une précontrainte différente, on peut prévoir une butée 48 solidaire du boítier 49 contre laquelle les deux replis 45a, 46a des tringles sont repoussées par les ressorts. Cette butée détermine par ailleurs une position initiale précise des éléments de retenue indépendamment l'un de l'autre.To give springs 43 and 44 a different prestress, one can provide a stop 48 secured to the housing 49 against which the two folds 45a, 46a of the rods are repelled by the springs. This stop also determines a precise initial position of the retaining elements independently of each other.

    Selon la variante de mise en oeuvre schématisée dans la figure 8 le mécanisme de rappel à ressort ne comprend qu'un ressort 50 en appui d'un côté sur le repli 5 la de l'une des tringles 51 et de l'autre sur une paroi du boítier 59. According to the implementation variant shown diagrammatically in FIG. 8, the spring return only includes a spring 50 bearing on one side on the fold 5 la of one of the rods 51 and the other on a wall of the housing 59.

    Par ailleurs le déplacement relatif des deux tringles 51 et 52 est synchronisé par exemple par l'intermédiaire d'une roue dentée 54 qui coopère avec deux crémaillères en vis-à-vis 56, 57 portées par chacune des extrémités des tringles.Furthermore, the relative movement of the two rods 51 and 52 is synchronized by example by means of a toothed wheel 54 which cooperates with two opposite racks 56, 57 carried by each of the ends of the rods.

    La roue dentée pivote autour d'un axe qui est monté fixe par rapport au boítier 59.The toothed wheel pivots about an axis which is mounted fixed relative to the housing 59.

    Selon le mode de réalisation illustré, l'axe de la roue dentée est orienté transversalement par rapport à la direction longitudinale définie par le ski. Ceci n'est pas limitatif et on pourrait utiliser une roue dentée à axe vertical comme cela est déjà connu.According to the illustrated embodiment, the axis of the toothed wheel is oriented transversely to the longitudinal direction defined by the ski. this is not limiting and one could use a toothed wheel with vertical axis as is already known.

    Comme dans le cas précédent le déplacement des éléments de retenue qui résulte de l'effort de pincement est partagé entre les deux éléments de retenue. A la différence du cas précédent la roue dentée 54 impose aux deux éléments de retenue des déplacements de même amplitude. De plus la course de compression du ressort 50 est la moitié du déplacement cumulé des deux éléments.As in the previous case, the displacement of the retaining elements which results from the pinching force is shared between the two retaining elements. Unlike the case previous the toothed wheel 54 forces the two retaining elements to move in the same way amplitude. In addition the compression stroke of the spring 50 is half the displacement cumulative of the two elements.

    Le mode de mise en oeuvre des figures 9 et 10 fait également appel à un dispositif de synchronisation, en l'occurrence un disque 62.The embodiment of FIGS. 9 and 10 also calls for a device for synchronization, in this case a disk 62.

    Les extrémités des deux tringles 63 et 64 sont superposées et glissent l'une relativement à l'autre.The ends of the two rods 63 and 64 are superimposed and slide one relative to each other.

    Dans la zone de superposition chaque tringle a une découpe rectangulaire, respectivement 63a , 64a dans laquelle est logé le ressort 70 en appui contre les extrémités de chacune des découpes. Les deux découpes 63a et 64a ont la même longueur. Dans ces conditions le ressort 70 assure un rappel relatif des deux tringles dans la position où les deux découpes sont superposées.In the overlapping area each rod has a rectangular cutout, respectively 63a, 64a in which is housed the spring 70 bearing against the ends of each of the cuts. The two cutouts 63a and 64a have the same length. In these conditions the spring 70 ensures a relative return of the two rods in the position where the two cutouts are superimposed.

    Chaque tringle a une extension latérale, respectivement 63b, 64b. Les deux extensions sont situées de part et d'autre de la direction longitudinale définie par les tringles.Each rod has a lateral extension, respectively 63b, 64b. The two extensions are located on either side of the longitudinal direction defined by the rods.

    Le disque 62 est monté pivotant sur un plot 67 en saillie au fond du boítier 68. Le disque 62 a deux tiges 62a, 62b diamétralement opposées et perpendiculaires au plan du disque qui sont engagées dans des lumières oblongues 63c, 64c des extensions latérales 63b, 64b.The disc 62 is pivotally mounted on a stud 67 projecting from the bottom of the housing 68. The disc 62 has two rods 62a, 62b diametrically opposite and perpendicular to the plane of the disc which are engaged in oblong slots 63c, 64c of the lateral extensions 63b, 64b.

    Les lumières oblongues 63c, 64c sont positionnées par rapport aux découpes 63a, 64a un peu au-delà du milieu de la longueur de la découpe, en direction de l'extrémité de la tringle.The oblong slots 63c, 64c are positioned relative to the cutouts 63a, 64a a little beyond the middle of the length of the cut, towards the end of the rod.

    De cette façon le déplacement des tiges 62a, 62b lié à la rotation du disque se fait de part et d'autre d'une direction orthogonale à la direction des tringles et passant par le centre du disque.In this way the displacement of the rods 62a, 62b linked to the rotation of the disc is done on either side of a direction orthogonal to the direction of the rods and passing through the center of the disc.

    La course de compression du ressort est ici égale au cumul des courses de déplacement des deux éléments de retenue avant et arrière, et le disque assure un déplacement synchronisé des deux éléments.The spring compression stroke is here equal to the cumulative displacement strokes of the two front and rear retaining elements, and the disc ensures synchronized movement of the two elements.

    En variante on pourrait jouer sur la position relative des deux tiges 62a et 62b. Notamment en rapprochant l'une des deux tiges du centre du disque, tout en conservant leur alignement, on pourrait introduire un rapport proportionnel dans le déplacement des deux éléments de retenue.Alternatively we could play on the relative position of the two rods 62a and 62b. In particular by bringing one of the two rods closer to the center of the disc, while retaining their alignment, we could introduce a proportional relationship in the displacement of the two retainers.

    En plaçant les deux tiges dans une position non alignée par rapport au centre du disque on pourrait introduire un rapport de déplacement non linéaire qui varie selon la position angulaire du disque.By placing the two rods in an unaligned position relative to the center of the disc one could introduce a nonlinear displacement ratio which varies according to the position disc angle.

    En variante, à la place du disque on pourrait utiliser une simple plaquette longiligne avec les deux tiges et un logement pour le plot 67. Ou encore on pourrait utiliser un dispositif du type losange déformable. Dans ce cas deux sommets opposés du losange seraient liés aux tringles. Les deux autres sommets seraient guidés dans le boítier par exemple dans des lumières oblongues dirigées perpendiculairement à la direction longitudinale des tringles. Au lieu d'un losange on pourrait avoir un quadrilatère déformable symétrique par rapport à la direction longitudinale des tringles.Alternatively, instead of the disc, a simple slender pad could be used with the two rods and a housing for the stud 67. Or we could use a device deformable diamond type. In this case two opposite vertices of the rhombus would be linked to the rods. The other two vertices would be guided in the case for example in oblong lights directed perpendicular to the longitudinal direction of the rods. At instead of a rhombus we could have a symmetrical deformable quadrilateral with respect to the longitudinal direction of the rods.

    Un des avantages de ce mode de construction est que l'ensemble des efforts liés à la compression du ressort est localisé dans les plans des deux tringles, ces plans étant très proches l'un de l'autre.One of the advantages of this construction method is that all of the efforts linked to the compression of the spring is located in the planes of the two rods, these planes being very close to each other.

    Selon le mode de mise en oeuvre illustré dans les figures 11 à 13, le déplacement symétrique des deux tringles 74 et 75 est contrôlé par une roue dentée 76 à deux étages, à la fois pour un réglage de position des éléments de retenue avant pour la pratique du ski, et pour le pincement de la chaussure au cours de la pratique du ski.According to the mode of implementation illustrated in FIGS. 11 to 13, the displacement symmetrical of the two rods 74 and 75 is controlled by a two-stage toothed wheel 76, at the times for adjusting the position of the front retaining elements for skiing, and for toe-in of the boot during skiing.

    Par exemple comme cela est représenté, un premier étage 77 de la roue dentée 76 est en prise avec les deux crémaillères 79, 80 en vis-à-vis que les tringles portent à leur extrémité.For example as shown, a first stage 77 of the toothed wheel 76 is in engagement with the two racks 79, 80 vis-à-vis that the rods carry at their end.

    Un second étage 81 de la roue dentée 76 est en prise avec un verrou 82 de blocage en rotation, le second étage n'est représenté que de façon partielle dans la figure 11 pour des raisons de clarté. Le verrou est manoeuvrable à l'aide d'un levier 83 accessible de l'extérieur. Dans l'une de ses positions le verrou est en prise avec l'étage 81 de la roue dentée qu'il immobilise en rotation, dans l'autre l'étage est débrayé en rotation. De préférence il est rappelé par un ressort dans sa position de blocage de l'étage 81.A second stage 81 of the toothed wheel 76 is engaged with a lock 82 for blocking in rotation, the second stage is only partially shown in Figure 11 for reasons of clarity. The lock is operable using a lever 83 accessible from the outside. In one of its positions, the lock is engaged with the stage 81 of the toothed wheel which it immobilizes in rotation, in the other the stage is disengaged in rotation. Preferably it is returned by a spring in its blocking position of the stage 81.

    Les deux étages de la roue dentée 76 sont montés sur le même axe de rotation l'un au-dessus de l'autre et sont reliés par un ressort de torsion 85 situé par exemple dans un logement réparti entre les deux étages.The two stages of the toothed wheel 76 are mounted on the same axis of rotation, one above on the other and are connected by a torsion spring 85 located for example in a housing distributed between the two floors.

    Un réglage de la position longitudinale des éléments de retenue peut être réalisé par une action sur le verrou 82. Dans ce cas les deux étages de la roue dentée tournent ensemble ce qui impose un déplacement symétrique des corps.The longitudinal position of the retaining elements can be adjusted by action on the lock 82. In this case the two stages of the toothed wheel rotate together which requires a symmetrical displacement of the bodies.

    Une fois que l'étage 81 se trouve verrouillé, le déplacement relatif des corps est encore possible contre la force de rappel exercée par le ressort 85 qui est induite par une rotation de l'étage 77 par rapport à l'étage 81.Once the stage 81 is locked, the relative movement of the bodies is still possible against the restoring force exerted by the spring 85 which is induced by a rotation of stage 77 relative to stage 81.

    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 given for information only and we could adopt other implementations of the invention without departing from the scope thereof.

    Notamment le boítier est facultatif, sa fonction principale est de fournir aux tringles et aux ressorts une référence fixe sur le ski. D'autres moyens pourraient convenir pour cela. Par exemple le mécanisme à ressort pourrait être logé dans la partie avant d'une pièce d'habillage de l'une des glissières.In particular the case is optional, its main function is to provide the rods and to springs a fixed reference on the ski. Other means may be suitable for this. Through example the spring mechanism could be housed in the front part of a trim piece from one of the slides.

    Egalement le boítier pourrait avoir une position longitudinale variable sur le ski de façon à rendre possible un réglage de position longitudinale de l'ensemble de retenue.Also the case could have a variable longitudinal position on the ski so as to make it possible to adjust the longitudinal position of the retaining assembly.

    De plus, au lieu que les glissières soient montées fixes sur le ski, on pourrait les monter de façon oscillante autour d'un axe transversal qui traverse la structure du ski.In addition, instead of the slides being fixedly mounted on the ski, they could be mounted oscillating around a transverse axis which crosses the structure of the ski.
