Abstract

The assembly has a base surmounted by a hollow body (3) and extending rearwardly into a supporting plate (5) for the sole of a shoe. The shoe is retained by two wings (7, 8) articulated around vertical axes (9, 10). Forces applied by the shoe on the wings are transmitted to a spring (12) by a cylindrical longitudinal link (13) with a screw (15) and washer (14). The triggering threshold is adjustable using of a floating rocker (25) and collar (24) actuated by either a magnet or an transmitter/ receiver assembly. The adjustment can also be done using an electric motor.

L'invention concerne également un ensemble de deux éléments de retenue associé à un ensemble de deux chaussures droite et gauche pour chacun des pieds d'un skieur.The invention also relates to a set of two retaining elements paired with a set of two right and left shoes for each of feet of a skier.

Dans le cas du ski alpin, il est connu de retenir une chaussure en appui sur un ski par l'intermédiaire d'un élément de fixation avant et un élément de fixation arrière qui retiennent des embouts avant et arrière de la chaussure. Ces deux éléments de fixation comprennent une mâchoire portée par un corps. La mâchoire est mobile en réponse aux sollicitations de la chaussure contre la force de rappel d'un ressort qui s'oppose à son déplacement.In the case of alpine skiing, it is known to retain a boot resting on a ski via a front binding element and a binding element rear that retain front and rear end pieces of the shoe. These two fasteners include a jaw carried by a body. Jaw is movable in response to the stresses of the shoe against the restoring force of a spring which opposes its displacement.

La raideur du ressort est réglable, de façon que la chaussure soit libérée de l'élément de fixation pour une sollicitation dépassant un seuil de sollicitation déterminé. Ce seuil est couramment dénommé seuil de déclenchement.The stiffness of the spring is adjustable, so that the shoe is released from the fastening element for a stress exceeding a stress threshold determined. This threshold is commonly referred to as the trigger threshold.

Pour pouvoir utiliser des chaussures avec les différents éléments de fixation du marché, la forme des embouts avant et arrière de la chaussure a été normalisée. Dans le système de normalisation ISO, la norme en application a la référence ISO 5355. Les éléments de fixation, quant à eux, sont prévus pour être compatibles avec les zones normalisées de la chaussure et assurer la libération de la chaussure à des valeurs de déclenchement déterminées.To be able to use shoes with the different fasteners on the market, the shape of the front and rear tips of the shoe has been standardized. In the ISO standardization system, the applicable standard has the ISO 5355 reference. The fastening elements are designed to be compatible with the standardized areas of the shoe and ensure the release of the shoe has determined trigger values.

A l'avant, une chaussure est retenue par un élément de fixation ou de retenue avant dont la mâchoire est mobile au moins latéralement vers l'intérieur ou l'extérieur du pied. La mâchoire de l'élément de retenue est prévue pour déclencher, c'est-à-dire pour libérer la chaussure lors d'une sollicitation en torsion excessive s'exerçant sur la jambe du skieur. Les fixations actuelles présentent un seuil de déclenchement en général égal vers l'intérieur et vers l'extérieur du pied.At the front, a shoe is held by a fastening or retaining element front whose jaw is movable at least laterally inward or the outside of the foot. The jaw of the retainer is provided for trigger, i.e. to release the shoe during torsional stress excessive exercise on the skier's leg. The current bindings present a trigger point generally equal inward and outward of the foot.

Or, on sait que le genou du skieur, qui est sollicité lors d'une chute en torsion est plus fragile pour une rotation du pied vers l'intérieur que pour une rotation vers l'extérieur.However, we know that the skier's knee, which is stressed during a torsional fall is more fragile for a rotation of the foot inwards than for a rotation towards outside.

Pour tenir compte de cela, on a proposé des éléments de fixation qui présentent un seuil de déclenchement différent selon le sens de basculement de la mâchoire. De tels éléments sont par exemple décrits dans les brevets français FR 1 503 847, 1 503 848, 1 503 849, ou encore dans la demande de brevet allemand publiée sous le numéro 18 07 074 sur lesquels se base le préambule de la revendication 1.To account for this, fasteners have been proposed which have a different trigger threshold depending on the direction of tilting of the jaw. Such elements are for example described in French patents FR 1 503 847, 1 503 848, 1 503 849, or even in the patent application German published under number 18 07 074 on which the preamble of claim 1.

L'inconvénient majeur de ce genre de dispositif est qu'il exige un appariement entre les chaussures et les skis, c'est à dire que les skis droit et gauche doivent être nécessairement repérés, et que le skieur doit surtout chausser le ski droit avec sa chaussure droite et le ski gauche avec la chaussure gauche. Cependant, il est matériellement possible d'inverser les deux skis, c'est à dire de chausser par exemple le ski gauche avec la chaussure droite. Dans ce cas, l'effet de la dissymétrie dans le déclenchement de la fixation joue de façon inverse, sans qu'il soit possible d'y remédier autrement qu'en échangeant les deux skis.The major disadvantage of this kind of device is that it requires pairing between the boots and the skis, i.e. the right and left skis must be necessarily identified, and that the skier must above all put on the right ski with his right shoe and left ski with left shoe. However, it is materially possible to reverse the two skis, i.e. to put on example the left ski with the right shoe. In this case, the effect of the asymmetry in the triggering of the fixation plays in reverse, without it is possible to remedy it other than by exchanging the two skis.

Le problème posé par l'invention est d'améliorer le mode de fonctionnement des éléments de retenue existants. Il consiste en particulier à pourvoir les éléments de retenue d'un seuil de déclenchement dissymétrique, et à améliorer le fonctionnement de tels éléments de retenue à seuil de déclenchement dissymétrique.The problem posed by the invention is to improve the operating mode existing retainers. It consists in particular in providing the elements to retain an asymmetric trigger threshold, and to improve the operation of such trigger threshold retaining elements asymmetrical.

Ce problème est résolu par l'ensemble des éléments de retenue d'une chaussure tel qu'il est défini ci-après, en particulier dans la revendication 1.This problem is solved by all of the retaining elements of a shoe as defined below, in particular in claim 1.

Chaque élément de retenue présente une mâchoire de retenue de la chaussure mobile latéralement, des deux côtés, vers l'intérieur ou l'extérieur du ski, contre la force de rappel d'un ressort. La mâchoire et le ressort sont prévus pour libérer la chaussure au-delà d'un seuil de déclenchement déterminé. Chaque élément de retenue est en plus équipé d'un mécanisme d'ajustement, qui permet de régler à volonté le seuil de déclenchement de l'élément de retenue de façon dissymétrique, d'après le sens de déplacement de la mâchoire, et d'un actionneur du mécanisme d'ajustement qui est commandé par l'autre élément de retenue de la paire. Ainsi, en présentant ses skis à plat sur le sol, et en les chaussant, les éléments de retenue se polarisent l'un vis à vis de l'autre de façon automatique, ou moyennant une manoeuvre simple des skis.Each retaining element has a jaw retaining jaw shoe movable laterally, on both sides, towards the inside or outside of the ski, against the return force of a spring. The jaw and the spring are provided for release the shoe beyond a determined trigger threshold. Each retaining element is additionally equipped with an adjustment mechanism, which allows adjust the trigger level of the retaining element as desired asymmetrical, according to the direction of movement of the jaw, and an actuator of the adjustment mechanism which is controlled by the other retaining element of the pair. Thus, by presenting his skis flat on the ground, and putting them on, the retainers automatically polarize against each other, or with a simple operation of the skis.

Cette polarisation des éléments de retenue se produit au moment du chaussage des skis, si bien que, quel que soit le sens dans lequel le skieur présente ses skis, chaque élément de retenue se polarisera d'après sa position droite ou gauche relative à l'autre élément.This polarization of the retaining elements occurs at the time of putting on the skis, so whatever the direction in which the skier presents its skis, each retaining element will polarize according to its position right or left relative to the other element.

A la suite de cette polarisation, le seuil de déclenchement de chacun des éléments de retenue est plus faible pour une libération de la chaussure vers l'extérieur que pour une libération vers l'intérieur de l'élément de retenue.Following this polarization, the triggering threshold for each of the retainers is weaker for release of the shoe towards outside only for inward release of the retainer.

L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below and the annexed drawings which form an integral part thereof.

Les figures 1 à 3 représentent à titre d'illustration de l'invention un élément de retenue 1. Les deux éléments de retenue de l'ensemble sont construits de façon identique. Pour simplifier la notation des références, on conviendra d'affecter les mêmes références aux mêmes organes des deux éléments de retenue, lorsqu'ils sont désignés de façon générale, et d'affecter à ces références l'exposant prime ou l'exposant seconde lorsqu'ils sont désignés en tant qu'organe spécifique de l'élément de retenue prime ou l'élément de retenue seconde, respectivement, de l'ensemble.Figures 1 to 3 show by way of illustration of the invention an element of retaining 1. The two retaining elements of the assembly are constructed so identical. To simplify the notation of the references, it will be advisable to assign the same references to the same members of the two retainers, when are designated generally, and to assign to these references the prime exhibitor or the second exhibitor when they are designated as a specific body for the premium retainer or the secondary retainer, respectively, of all.

L'élément 1 représenté dans les figures 1 à 3 comprend une embase 2 surmontée d'un corps creux ou capot 3 présentant une paroi latérale et un capot supérieur. L'embase 2 se prolonge vers l'arrière pour former une plaque d'appui 5 prévue pour recevoir la semelle de chaussure. Element 1 shown in Figures 1 to 3 includes a base 2 surmounted by a hollow body or cover 3 having a side wall and a cover superior. The base 2 extends rearward to form a support plate 5 intended to receive the shoe sole.

L'élément de retenue présente en outre une mâchoire formée de deux ailes 7 et 8 de retenue de la chaussure. Dans leur mode de représentation illustré dans les figures, les ailes sont indépendantes, respectivement articulées autour d'axes verticaux 9 et 10. Les ailes se prolongent respectivement vers l'intérieur, au-delà des axes 9 et 10 par des retours 7a et 8a. En outre, les ailes comprennent un serre-semelle qui assure la retenue verticale de la chaussure, en plus de la retenue latérale. Ceci n'est pas limitatif, et la mâchoire pourrait avoir une autre nature, notamment être monobloc, reliée de façon solidaire à un corps monté pivotant autour d'un pivot central. De nombreuses constructions connues sont possibles. Au repos, la mâchoire présente une position sensiblement alignée avec l'axe longitudinal défini par le ski. Dans le cas illustré, au repos, les ailes 7 et 8 sont refermées vers l'axe longitudinal médian que l'on a schématisé par sa trace 11 dans la figure 2.The retaining element also has a jaw formed by two wings 7 and 8 for retaining the shoe. In their mode of representation illustrated in figures, the wings are independent, respectively articulated around axes vertical 9 and 10. The wings extend inward respectively, beyond axes 9 and 10 by returns 7a and 8a. In addition, the wings include a sole clamp which ensures the vertical retention of the shoe, in addition to the retention lateral. This is not limiting, and the jaw could have another nature, in particular be in one piece, integrally connected to a pivotally mounted body around a central pivot. Many known constructions are possible. At rest, the jaw has a position substantially aligned with the axis longitudinal defined by the ski. In the illustrated case, at rest, the wings 7 and 8 are closed towards the median longitudinal axis which is shown diagrammatically by its trace 11 in figure 2.

Le corps 3 de l'élément de retenue abrite un ressort 12, à qui sont transmises les sollicitations que la chaussure exerce sur les ailes de la mâchoire, et qui, en retour, exerce sur les ailes une force de rappel élastique en direction de leur position de repos respective.The body 3 of the retaining element houses a spring 12, to which are transmitted the stresses that the shoe exerts on the wings of the jaw, and which, in back, exerts on the wings an elastic return force towards their respective rest position.

Le ressort est relié à la mâchoire par une liaison de transmission de mouvement.The spring is connected to the jaw by a transmission link of movement.

Dans le mode de réalisation représenté dans les figures 1 à 3, la liaison entre le ressort et les ailes de la mâchoire comprend un tirant longitudinal 13 qui est cylindrique. Le tirant est engagé dans les spires du ressort. Il présente à son extrémité avant une rondelle d'arrêt 14 contre laquelle l'extrémité avant du ressort s'appuie. La rondelle est reliée à l'extrémité du ressort par une vis 15 qui permet de régler la compression initiale du ressort. La vis 15 est accessible depuis l'avant de l'élément de retenue au travers d'une ouverture du capot.In the embodiment shown in Figures 1 to 3, the connection between the spring and the wings of the jaw comprises a longitudinal tie rod 13 which is cylindrical. The tie rod is engaged in the turns of the spring. He presents to his front end a stop washer 14 against which the front end of the spring relies. The washer is connected to the end of the spring by a screw 15 which allows adjust the initial compression of the spring. Screw 15 is accessible from the front of the retainer through a hood opening.

Vers l'arrière, le ressort est en appui contre une paroi d'appui 18 qui est solidaire du corps ou de son embase. Dans le mode de réalisation illustré, la paroi d'appui 18 sert également de butée pour les retours 7a et 8a des ailes, pour une rotation des ailes vers l'intérieur. Cette position en butée contre la paroi d'appui définit la position de repos de chacune des ailes. Le tirant traverse la paroi 18 et débouche vers l'arrière entre les deux ailes. A ce niveau, il présente une partie 20 de diamètre plus petit, avec une tête 21. A la naissance de cette partie de plus faible diamètre, le tirant présente un épaulement 22. Sur la partie de plus faible diamètre sont montés une bague 24, du côté de l'épaulement 22, et un basculeur flottant 25 du côté de la tête 21. Le basculeur flottant est plus large que la tête 21, et ses dimensions sont telles qu'il offre aux retours 7a et 8a des ailes une surface d'appui par laquelle les retours des ailes peuvent solliciter le tirant d'avant en arrière contre la force de rappel du ressort. Avantageusement, la partie 20 de plus petit diamètre est un élément indépendant qui est assemblé par exemple par vissage ou tout autre moyen approprié au reste du tirant.Towards the rear, the spring bears against a support wall 18 which is secured to the body or its base. In the illustrated embodiment, the wall support 18 also serves as a stop for the returns 7a and 8a of the wings, for a wing rotation inward. This position in abutment against the support wall defines the rest position of each wing. The tie rod crosses the wall 18 and opens backwards between the two wings. At this level, it presents a part 20 of smaller diameter, with a head 21. At the birth of this part more small diameter, the tie has a shoulder 22. On the weakest part diameter are mounted a ring 24, on the side of the shoulder 22, and a rocker floating 25 on the side of the head 21. The floating rocker is wider than the head 21, and its dimensions are such that it gives the returns 7a and 8a of the wings a surface support by which the returns of the wings can stress the front tie in back against the spring return force. Advantageously, part 20 more small diameter is an independent element which is assembled for example by screwing or any other means suitable for the rest of the tie rod.

Le basculeur 25 est maintenu sur la partie 20 du tirant, en appui entre sa tête 21 et les retours 7a et 8a des ailes. De préférence, la tête 21 du tirant a une section carrée, et le tirant présente latéralement deux bourrelets qui donnent un bon appui pour le basculeur, notamment au cours des mouvements d'oscillation qui seront décrits ultérieurement. Vers l'avant, le basculeur 25 est en appui contre la bague 24. La bague 24 est montée pivotante autour de la partie 20 du tirant. Vers l'avant, la bague s'appuie contre l'épaulement 22. De façon avantageuse, la bague présente un diamètre extérieur égal à celui de la partie avant du tirant, mais ce n'est pas essentiel. De préférence également, la bague présente une longueur supérieure à la course du tirant entre la position de repos et la libération de la chaussure. L'ensemble du basculeur et de la bague est prévu pour que, au moins au repos, la bague puisse pivoter librement autour de la partie 20. C'est-à-dire que le basculeur et la bague sont montés sur le tirant, entre la tête et l'épaulement 22 avec un léger jeu selon une direction longitudinale.The rocker 25 is held on the part 20 of the tie rod, resting between its head 21 and returns 7a and 8a of the wings. Preferably, the head 21 of the tie rod has a section square, and the tie has two beads laterally which give good support for the rocker, especially during the oscillating movements which will be described later. Forward, the rocker 25 bears against the ring 24. The ring 24 is pivotally mounted around the part 20 of the tie rod. Forward, the ring bears against the shoulder 22. Advantageously, the ring has an outside diameter equal to that of the front part of the tie rod, but this is not essential. Also preferably, the ring has a length greater than the travel of the tie rod between the rest position and the release of the shoe. The assembly of the rocker and the ring is provided so that, at least at rest, the ring can pivot freely around part 20. That is to say than the rocker and the ring are mounted on the tie rod, between the head and the shoulder 22 with slight play in a longitudinal direction.

Le basculeur 25 est flottant, c'est à dire qu'il peut osciller dans un plan horizontal, en fonction de la position et du déplacement de ses différents appuis.The rocker 25 is floating, i.e. it can oscillate in a plane horizontal, depending on the position and displacement of its various supports.

Dans le mode de réalisation représenté, le basculeur présente une large ouverture centrale 27 de forme rectangulaire. Vue de dessus, la largeur de cette ouverture est supérieure au diamètre de la partie 20 du tirant, et, de préférence, cette partie 20 présente une collerette 28 à bord arrondi, dont le diamètre extérieur es sensiblement égal à la largeur de l'ouverture 27. Cette collerette sert d'appui à l'oscillation du basculeur, qui sera décrite plus en détail ultérieurement. La largeur de l'ouverture 27 est cependant inférieure au diamètre de la bague 24.In the embodiment shown, the rocker has a wide central opening 27 of rectangular shape. Top view, the width of this opening is greater than the diameter of part 20 of the tie rod, and preferably this part 20 has a flange 28 with a rounded edge, the outside diameter of which are substantially equal to the width of the opening 27. This flange serves to support the oscillation of the rocker, which will be described in more detail later. The width of the opening 27 is however less than the diameter of the ring 24.

Vue de côté, l'ouverture 27 présente une hauteur qui est légèrement supérieure au diamètre extérieur de la bague 25. La partie 20 du tirant est maintenue à mi-hauteur de l'ouverture 27 par tout moyen approprié.Side view, the opening 27 has a height which is slightly greater than the outside diameter of the ring 25. The part 20 of the tie rod is maintained at mid-height of the opening 27 by any appropriate means.

La bague 24 présente du côté du basculeur une surface d'appui plane, qui est verticale, sauf sur un quart de cercle environ où la surface d'appui est en retrait. La zone plane et verticale est repérée en 29 dans les figures, et la zone en retrait en 30. Dans la position de la bague représentée dans les figures 1 et 2, cette zone 30 se trouve alignée avec le plan longitudinal médian, vers le haut, au-dessus de la partie 20 du tirant. Elle pourrait aussi bien être au-dessous de la partie 20. Cette position sera qualifiée dans la suite de position médiane.The ring 24 has on the side of the rocker a flat bearing surface, which is vertical, except for about a quarter of a circle where the support surface is recessed. The flat and vertical area is identified at 29 in the figures, and the recessed area at 30. In the position of the ring shown in FIGS. 1 and 2, this zone 30 is aligned with the median longitudinal plane, upwards, above of the part 20 of the tie. It might as well be below part 20. This position will be qualified in the following middle position.

La construction qui vient d'être décrite fonctionne de la façon suivante. Les figures 7 et 8 représentent la liaison entre la ailes et le tirant dans la position médiane de la bague. Dans la figure 7, les ailes sont au repos, en position fermée. Dans la figure 8, l'une des ailes, l'aile 7 en l'occurrence, s'est ouverte. Le retour 8a de l'aile a entraíné le basculeur 25. Le basculeur 25 est maintenu d'un côté par la tête 20 du tirant, et de l'autre côté, par réaction, il s'appuie contre la bague 24 de part et d'autre de l'axe longitudinal médian. Le basculeur se déplace avec le tirant en restant perpendiculaire au tirant.The construction which has just been described operates in the following manner. The Figures 7 and 8 show the connection between the wings and the tie in the position middle of the ring. In Figure 7, the wings are at rest, in the closed position. In FIG. 8, one of the wings, the wing 7 in this case, has opened. The return 8a of the wing has driven the rocker 25. The rocker 25 is held on one side by the head 20 of the tie rod, and on the other side, by reaction, it bears against the ring 24 of on either side of the median longitudinal axis. The rocker moves with the tie rod staying perpendicular to the tie.

La figure 9 représente la construction après une rotation de la bague 24 sur un quart de tour. Cette rotation a amené la zone en retrait 30 du basculeur vers le retour 8a de l'aile 8.Figure 9 shows the construction after a rotation of the ring 24 on a quarter turn. This rotation brought the recessed area 30 from the rocker towards the return 8a of wing 8.

Dans la figure 10, l'aile 8 s'est ouverte. Dans son mouvement de rotation, l'aile a entraíné le basculeur 25. Le basculeur s'appuie sur la tête du tirant, et, par réaction sur la bague 24 dans la zone diamétralement opposée à la zone 30. Le basculeur se comporte de la même façon que ce qui a été décrit précédemment.In Figure 10, wing 8 has opened. In its rotational movement, the wing has driven the rocker 25. The rocker rests on the head of the tie rod, and, by reaction on the ring 24 in the zone diametrically opposite to the zone 30. The rocker behaves in the same way as that described above.

La figure 11 illustre la rotation de l'autre aile, c'est-à-dire l'aile 7. Comme précédemment, le basculeur entraíne la tête 21 du tirant, mais cette fois-ci, le basculeur s'appuie par réaction non plus contre la bague 24, mais contre le retour 8a de l'autre aile. En effet, le basculeur ne peut pas trouver un appui contre la bague 24, à cause de la zone en retrait 30. L'aile 8 est quant à elle retenue par la paroi d'appui 18. Le basculeur 25 ne transmet plus directement son mouvement au tirant, il fonctionne comme un lever, qui pivote par appui sur le retour 8a. Compte tenu de la différence de bras de lever, la force de rappel qui s'oppose à l'ouverture de l'aile est démultipliée. L'ouverture de l'aile 7a est facilitée dans cette position de la bague 24.Figure 11 illustrates the rotation of the other wing, i.e. wing 7. As previously, the rocker drives the head 21 of the tie rod, but this time, the rocker rests by reaction no longer against ring 24, but against return 8a on the other wing. Indeed, the rocker cannot find a support against the ring 24, because of the recessed area 30. The wing 8 is in turn retained by the support wall 18. The rocker 25 no longer directly transmits its movement to the pulling, it works like a lever, which pivots by pressing on the return 8a. Account given the difference in arm lift, the restoring force that opposes the opening of the wing is multiplied. The opening of the wing 7a is facilitated in this position of ring 24.

De préférence, la zone 30 est suffisamment en retrait pour que l'aile 7 libère la chaussure avant que le basculeur 25 atteigne le fond de la zone 30. De cette façon, le basculeur 30 reste en appui contre le retour de l'aile 8, et l'effet démultiplicateur est maintenu. En outre, l'ouverture 27 du basculeur 30 est prévue en hauteur pour ne pas gêner l'oscillation du basculeur, c'est-à-dire qu'elle est supérieure au diamètre extérieur de la bague.Preferably, the zone 30 is sufficiently set back so that the wing 7 releases the shoe before the rocker 25 reaches the bottom of the zone 30. In this way, the rocker 30 remains in abutment against the return of the wing 8, and the reduction effect is maintained. In addition, the opening 27 of the rocker 30 is provided in height for do not interfere with the swing of the rocker, i.e. it is greater than the outer diameter of the ring.

Il va de soi que la bague 24 peut aussi être pivotée dans l'autre sens, pour obtenir le même effet démultiplicateur avec l'ouverture de l'autre aile.It goes without saying that the ring 24 can also be pivoted in the other direction, to obtain the same multiplier effect with the opening of the other wing.

L'élément de retenue comprend en outre des moyens de commande pour déterminer la position de la bague d'après la position relative de l'élément de retenue par rapport à l'autre élément de l'ensemble.The retaining element further comprises control means for determine the position of the ring from the relative position of the element retained with respect to the other element of the assembly.

Selon le mode de réalisation illustré, la bague 24 présente sur la moitié de sa périphérie une zone cannelée 34. Les cannelures sont orientées parallèlement à la direction longitudinale de déplacement du tirant. De préférence, dans la position médiane de la bague, cette zone est située sur le dessus de la bague.According to the illustrated embodiment, the ring 24 has on half of its periphery a grooved area 34. The grooves are oriented parallel to the longitudinal direction of travel of the tie rod. Preferably in the position middle of the ring, this area is located on top of the ring.

Une crémaillère 35 est prévue pour s'engrener sur les cannelures de la bague 24. La crémaillère 35 est guidée selon un mouvement de translation transversale dans une rainure portée par la paroi d'appui 18. Naturellement tout autre moyen approprié de guidage convient.A rack 35 is provided to mesh with the grooves of the ring 24. The rack 35 is guided in a translational movement transverse in a groove carried by the support wall 18. Naturally everything another suitable means of guidance is suitable.

De préférence, la crémaillère 35 ou la bague 24 présente des moyens de rappel élastique en position médiane, c'est-à-dire la position de fonctionnement correspondant aux figures 7 et 8. La crémaillère porte dans sa partie supérieure une tige 36 verticale. La tige 36 est accrochée entre deux ressorts transversaux 37a et 37b qui sont par ailleurs retenus par des butées solidaires du capot 3, et qui rappellent la tige 36 dans sa position médiane. Tout autre moyen approprié convient.Preferably, the rack 35 or the ring 24 has means of elastic return to the middle position, i.e. the operating position corresponding to Figures 7 and 8. The rack carries in its upper part a vertical rod 36. Rod 36 is hung between two transverse springs 37a and 37b which are also retained by stops integral with the cover 3, and which recall the rod 36 in its middle position. Any other appropriate means agrees.

Selon le mode de mise en oeuvre de l'invention représenté dans les figures 1 à 13, la crémaillère 35 est construite comme un aimant orienté nord-sud selon la direction horizontale et transversale de l'élément de retenue. Par exemple, la crémaillère est formée par un barreau aimanté rapporté au-dessus d'une plaquette neutre portant les dents. Le capot 3 et les autres organes de l'élément de retenue sont également réalisés dans un matériau neutre au rayonnement magnétique, par exemple une matière plastique, ou des alliages à base de métaux non ferreux.According to the mode of implementation of the invention shown in Figures 1 at 13, the rack 35 is constructed as a magnet oriented north-south according to the horizontal and transverse direction of the retaining element. For example, the rack is formed by a magnetic bar attached above a plate neutral bearing teeth. The cover 3 and the other members of the retaining element are also made of a material neutral to magnetic radiation, by for example a plastic material, or alloys based on non-ferrous metals.

L'orientation nord-sud est arbitraire, mais elle est identique pour les deux éléments d'une paire.The north-south orientation is arbitrary, but it is identical for both elements of a pair.

La figure 12 représente la bague 24 et la crémaillère 35 en position médiane.Figure 12 shows the ring 24 and the rack 35 in the middle position.

La figure 13 représente ces mêmes organes pour deux éléments de retenue placés côte à côte. Les éléments de retenue sont par exemple placés ainsi lorsque les skis sont posés à plat, prêts à être chaussés. Comme convenu, les organes de chaque élément ont été repérés respectivement avec les exposants prime et seconde (24', 24'', 35', 35'', ...).FIG. 13 represents these same members for two retaining elements placed side by side. The retaining elements are for example placed thus when the skis are laid flat, ready to be put on. As agreed, the organs of each element were identified respectively with the prime exhibitors and second (24 ', 24' ', 35', 35 '', ...).

Les deux aimants des crémaillères 35' et 35'' sont polarisés dans la même direction, si bien que quel que soit la position relative des deux éléments de retenue, les deux aimants s'attirent et se déplacent l'un vers l'autre.The two rack magnets 35 'and 35' 'are polarized in the same direction so that whatever the relative position of the two elements of retained, the two magnets attract and move towards each other.

Ils entraínent avec eux les bagues 24' et 24'' dans des sens de rotation inversés, ce qui aboutit à une polarisation symétrique de chacun des éléments de retenue.They drive with them the rings 24 'and 24' 'in directions of rotation reversed, which results in a symmetrical polarization of each of the elements of detention.

Par cette polarisation, les ailes qui sont situées vers l'extérieur de chacun des éléments de retenue sont prévues pour libérer la chaussure plus facilement, c'est-à-dire avec un seuil de déclenchement plus faible que les ailes intérieures. La chaussure du skieur sera de ce fait libérée pour une sollicitation en torsion de la jambe et du genou du skieur plus faible vers l'intérieur du pied que vers l'extérieur.By this polarization, the wings which are located towards the outside of each of the retainers are provided to release the shoe more easily, that is to say with a lower trigger threshold than the inner wings. The the skier's shoe will therefore be released for a torsional stress on the lower leg and knee of the skier towards the inside of the foot than towards the outside.

Pour éviter que la polarisation soit modifiée au cours de la pratique du ski, de préférence, un moyen de verrouillage bloque chaque bague une fois qu'elle a atteint sa position de polarisation. To prevent the polarization from being changed during skiing, preferably, a locking means blocks each ring once it has reaches its polarization position.

Dans les figures 1 à 13, ce moyen est représenté sous la forme d'un verrou 38 mobile verticalement sous la bague 24. Le verrou porte dans sa partie supérieure une dent 39 qui est prévue pour pouvoir l'engager dans une cannelure de la bague. Le verrou 38 est rappelé élastiquement vers le haut par un ressort 40 situé à sa partie inférieure.In Figures 1 to 13, this means is shown in the form of a lock 38 vertically movable under the ring 24. The lock carries in its upper part a tooth 39 which is provided to be able to engage it in a groove of the Ring. The lock 38 is resiliently biased upwards by a spring 40 located at its bottom.

Un palpeur de commande est prévu pour ramener le verrou 38 vers le bas, contre la force de rappel du ressort 40, ou bien pour le libérer à volonté. Le palpeur est ici la plaque d'appui de la chaussure qui présente une partie supérieure 41 mobile verticalement, et rappelée élastiquement vers le haut, par exemple par la déformation d'une zone élastiquement déformable formant charnière élastique située à l'arrière de la partie supérieure. De plus, une couche de matériau élastiquement déformable peut être interposée entre la partie 41 et le reste de la plaque, pour rappeler élastiquement la plaque, et aussi pour combler cet espace et éviter l'infiltration de neige ou de salissures.A control probe is provided to bring the lock 38 down, against the return force of the spring 40, or to release it at will. The feeler here is the support plate of the shoe which has an upper part 41 vertically movable, and spring-loaded upwards, for example by the deformation of an elastically deformable zone forming an elastic hinge located at the rear of the upper part. In addition, a layer of material elastically deformable can be interposed between part 41 and the rest of the plate, to elastically recall the plate, and also to fill this space and avoid the ingress of snow or dirt.

A l'avant, la partie supérieure 41 est en appui contre la branche d'un basculeur 42 mobile autour d'un axe transversal, dont l'autre branche est prévue pour abaisser le verrou 38, par exemple en prenant appui sur un rebord situé à sa base. Une petite languette reliée à l'extrémité mobile de la partie 41 reprend par dessous la branche du basculeur 42 pour asservir le mouvement du basculeur au mouvement de cette extrémité de la partie 41. Naturellement, tout autre moyen approprié convient.At the front, the upper part 41 bears against the branch of a rocker 42 movable about a transverse axis, the other branch of which is provided to lower the latch 38, for example by resting on a ledge located at its based. A small tab connected to the movable end of part 41 is taken up by below the rocker arm 42 to control the movement of the rocker to movement of this end of part 41. Naturally, any other means suitable suitable.

Le moyen de verrouillage fonctionne de la façon suivante. La mise en place des skis côte à côte provoque la translation transversale des crémaillère 35' et 35'', et la rotation des bagues 24' et 24'' sur une amplitude angulaire d'un quart de tour, pour amener les zones en retrait 30' et 30'' d'un côté et de l'autre de la partie 20 des tirants, respectivement. Pour chacune des bagues, cette rotation amène la première cannelure à l'aplomb de l'axe de la partie 20 du tirant, en regard de la dent 39 du verrou 38.The locking means operates as follows. The establishment side by side skis causes transverse translation of the 35 'and 35' 'racks, and the rotation of the rings 24 'and 24' 'over an angular amplitude of a quarter turn, to bring the 30 'and 30' 'recessed areas on one side and the other of part 20 tie rods, respectively. For each of the rings, this rotation brings the first groove in line with the axis of part 20 of the tie rod, opposite the tooth 39 of latch 38.

A l'engagement de la chaussure, la partie 41 de la plaque d'appui s'abaisse, libérant le verrou 38 qui remonte sous la poussée du ressort 40, ce qui provoque l'engagement de la dent 39 dans la cannelure, et le verrouillage de la bague. Les bagues sont immobilisées dans leur position respective tant que les chaussures sont engagées dans leur élément de retenue.When the shoe is engaged, the part 41 of the support plate lowers, releasing the latch 38 which rises under the thrust of the spring 40, which causes the engagement of tooth 39 in the groove, and the locking of the ring. The rings are immobilized in their respective position as long as the shoes are engaged in their retainer.

Il faut noter qu'au cours de la pratique du ski, la bague peut se déplacer selon une direction longitudinale avec le tirant, le verrou et la crémaillère ne se déplacent pas longitudinalement, mais ils glissent le long des cannelures dans lesquelles ils sont engagés respectivement.It should be noted that during skiing, the ring can move according to a longitudinal direction with the tie rod, the bolt and the rack do not move not longitudinally, but they slide along the grooves in which they are engaged respectively.

Le blocage de la bague par le verrou 38 peut se faire également après l'engagement de la chaussure. En effet, dans ce cas, à l'engagement de la chaussure, la dent 39 est repoussée contre la surface lisse de la bague, qui peut donc pivoter lors du rapprochement des deux éléments de retenue, jusqu'à ce que la première cannelure parvienne en regard de la dent 39. La dent immobilise alors la bague.The locking of the ring by the lock 38 can also be done after the engagement of the shoe. Indeed, in this case, the commitment of the shoe, tooth 39 is pushed against the smooth surface of the ring, which can therefore rotate when the two retaining elements are brought together, until the first groove reaches the tooth 39. The tooth then immobilizes the ring.

Lorsque la chaussure est libérée de l'élément de retenue, de façon accidentelle ou de façon volontaire, la partie 41 de la plaque d'appui remonte, ce qui ramène le verrou 38 vers le bas. La bague est libérée, et l'un des ressorts supérieurs 37a ou 37b, celui des deux qui a été étiré, rappelle la crémaillère 35 et la bague en position médiane.When the shoe is released from the retainer, so accidentally or voluntarily, part 41 of the backing plate rises, this which brings the lock 38 down. The ring is released, and one of the springs upper 37a or 37b, the one of the two which has been stretched, recalls rack 35 and the ring in the middle position.

De préférence, comme le représentent les figures 1 et 14, l'élément de retenue présente des voyants transparents 48 et 49, vers chaque bord, au travers desquels il est possible de voir la crémaillère 35, et donc de contrôler sa mise en place correcte. Dans la figure 14, les crémaillères 35' et 35'' sont visibles au travers des deux voyants extérieurs 48' et 48''. Naturellement, tout autre moyen approprié convient.Preferably, as shown in Figures 1 and 14, the element of retainer has transparent indicators 48 and 49, towards each edge, through which it is possible to see the rack 35, and therefore control its implementation correct place. In figure 14, the racks 35 'and 35' 'are visible through two exterior lights 48 'and 48' '. Naturally, any other appropriate means agrees.

Les figures 15 et 16 illustrent un autre mode de mise en oeuvre de l'invention. Ces figures représentent un élément de retenue 51 qui présente une structure identique à l'élément 1. On y retrouve le tirant, avec le basculeur, la bague et la crémaillère. Ces organes sont identiques aux éléments précédemment décrits, excepté le fait que la crémaillère n'est pas aimantée dans le cas présent.Figures 15 and 16 illustrate another embodiment of the invention. These figures represent a retaining element 51 which has a structure identical to element 1. We find the tie rod, with the rocker, the ring and the rack. These organs are identical to the elements previously described, except for the fact that the rack is not magnetized in this case.

La crémaillère 55 est surmontée comme dans le cas présent d'une tige 56. La tige 56 est manoeuvrée d'un côté et de l'autre par un lever longitudinal 57 qui s'étend vers l'avant de l'élément de retenue et qui est articulé dans sa partie centrale autour d'un axe vertical 58 fixé par exemple au capot 53. L'extrémité arrière du levier présente une fourche qui chevauche la tige 56 dans un plan horizontal. De l'autre côté de l'axe 58, le lever 57 présente une autre extrémité en forme de fourche, dans laquelle est engagée une tige verticale 60. La tige est portée par un curseur transversal 61 mobile en translation. Les deux extrémités 62 et 63 du curseur 61 traversent le capot 53 et font saillie latéralement.The rack 55 is surmounted as in the present case of a rod 56. The rod 56 is maneuvered on one side and on the other by a longitudinal lever 57 which extends towards the front of the retaining element and which is articulated in its part central around a vertical axis 58 fixed for example to the cover 53. The end rear of the lever has a fork which straddles the rod 56 in a plane horizontal. On the other side of the axis 58, the lever 57 has another end in fork shape, in which a vertical rod 60 is engaged. The rod is carried by a transverse cursor 61 movable in translation. The two ends 62 and 63 of the cursor 61 cross the cover 53 and project laterally.

La polarisation d'un élément de retenue se fait ici de façon mécanique par appui sur le curseur situé du côté de l'autre élément de retenue au moyen de l'autre élément, de l'autre ski ou de l'autre chaussure. Par exemple, le skieur engage se deux chaussures dans les deux éléments de retenue puis donne avec l'un de ses skis un coup contre l'extrémité intérieure du curseur de l'autre élément, et il renouvelle l'opération pour l'autre pied.The polarization of a retaining element is done here mechanically by press the cursor located on the side of the other retaining element by means of the other element, the other ski or the other shoe. For example, the skier engage two shoes in the two retaining elements then give with one of his skis hit against the inner end of the cursor of the other element, and he repeats the operation for the other foot.

Dans le cas présent, les extrémités du curseur permettent par leur position de contrôler l'état de polarisation de l'élément de retenue.In this case, the ends of the cursor allow by their position to check the polarization state of the retaining element.

Par cette polarisation, les ailes qui sont situées vers l'extérieur de chacun des éléments de retenue sont prévues pour libérer la chaussure plus facilement, c'est-à-dire avec un seuil de déclenchement plus faible que les ailes intérieures. La chaussure du skieur sera de ce fait libérée pour une sollicitation en torsion de la jambe et du genou du skieur plus faible vers l'intérieur du pied que vers l'extérieur.By this polarization, the wings which are located towards the outside of each of the retainers are provided to release the shoe more easily, that is to say with a lower trigger threshold than the inner wings. The the skier's shoe will therefore be released for a torsional stress on the lower leg and knee of the skier towards the inside of the foot than towards the outside.

L'élément qui vient d'être décrit peut présenter des moyens de rappel de la crémaillère en position centrale, et des moyens de verrouillage de la bague de même nature que ceux décrits précédemment, ou de nature équivalente.The element which has just been described may present means for recalling the rack in central position, and means for locking the ring same nature as those described above, or equivalent.

Les figures 17 et suivantes illustrent un autre mode de mise en oeuvre de l'invention. L'élément de retenue 71 représenté pour illustrer ce mode de réalisation présente une structure mécanique de même nature que ce qui a été décrit précédemment, avec notamment une embase 72, un capot 73, une plaque d'appui 75, des ailes de retenue 77 et 78, un ressort 82, un tirant 83, une paroi d'appui 88. Le tirant porte une bague 94 avec une zone cannelée 99 et un basculeur 95. La bague est ici manoeuvrée par un petit moteur électrique 96 présentant en sortie une roue dentée 97 au pas des cannelures de la bague 94. Le moteur et la roue sont prévus pour entraíner la bague sur une rotation d'un quart de tour de part et d'autre de sa position médiane, ce qui polarise l'élément de retenue en tant qu'élément droit ou élément gauche, ainsi que cela a été décrit en référence aux figures 7 à 11.FIGS. 17 et seq. Illustrate another embodiment of the invention. The retaining element 71 shown to illustrate this mode of realization presents a mechanical structure of the same nature as what was described above, with in particular a base 72, a cover 73, a plate support 75, retaining wings 77 and 78, a spring 82, a tie rod 83, a wall support 88. The tie-rod carries a ring 94 with a grooved zone 99 and a rocker 95. The ring is here operated by a small electric motor 96 presenting at the output a toothed wheel 97 with the pitch of the grooves of the ring 94. The motor and wheel are provided to drive the ring on a rotation of a quarter of round either side of its middle position, which polarizes the retainer as a right element or a left element, as described in reference to Figures 7 to 11.

Le moteur 96 est par exemple fixé à la paroi 88. Il est commandé par un circuit électronique comprenant de chaque côté de l'élément de retenue un organe émetteur, respectivement 103, 104, et un organe récepteur, respectivement 105, 106. Des schémas fonctionnels de ce circuit sont donnés à titre d'illustration dans les figures 20 et 21. Le moteur et le circuit électronique sont alimentés en courant par une batterie connue et couplés par des moyens électriques d'un type connu, qui ne seront pas décrits en détail. Avantageusement, les organes émetteurs et les organes récepteurs d'un même élément de retenue sont disposés en quinconce.The motor 96 is for example fixed to the wall 88. It is controlled by a circuit electronic comprising on each side of the retaining element a member transmitter, respectively 103, 104, and a receiving member, respectively 105, 106. Functional diagrams of this circuit are given by way of illustration in Figures 20 and 21. The motor and the electronic circuit are supplied with current by a known battery and coupled by electrical means of a known type, which will not be described in detail. Advantageously, the emitting organs and the receiving members of the same retaining element are staggered.

La figure 19 illustre le mode de fonctionnement de cet ensemble. Elle représente un ensemble de deux éléments de retenue 71' et 71'' placés côte à côte, dans la position où les skis sont prêts à être chaussés.Figure 19 illustrates the mode of operation of this assembly. She represents a set of two retaining elements 71 'and 71' 'placed side by side side, in the position where the skis are ready to be put on.

On voit dans la figure 19 que la disposition en quinconce des émetteurs et des récepteurs permet avantageusement d'avoir le récepteur 106' en regard de l'émetteur 103'', et inversement, l'émetteur 104' en regard du récepteur 105''. Chaque élément de retenue connaít donc sa position d'après le récepteur qui est activé.It can be seen in FIG. 19 that the staggered arrangement of the transmitters and the receivers advantageously makes it possible to have the receiver 106 ′ facing the transmitter 103 '', and conversely, the transmitter 104 'opposite the receiver 105' '. Each retaining element therefore knows its position according to the receiver which is activated.

Les organes émetteur et récepteur sont de tout type approprié. Ils sont prévus pour transmettre des signaux de façon directionnelle sur une courte distance. Ces signaux peuvent être codés. Par exemple il s'agit d'un émetteur et d'un récepteur de type infra-rouge du type de ceux utilisés dans les télécommandes de téléviseurs. Il peut s'agir aussi d'organes tels que ceux utilisés pour l'ouverture à distance de portails, ou le verrouillage centralisé des portes d'un véhicule. On pourrait aussi mettre en oeuvre des organes de type optique, avec organe émetteur de lumière et une cellule photo-électrique. On pourrait aussi utiliser des circuits plus complexes, par exemple de type résonnant ou des circuits utilisant un champ magnétique que l'on perturbe en introduisant dans le champ couvert un élément étranger de l'autre élément de retenue.The transmitting and receiving organs are of any suitable type. They are planned to transmit signals directionally over a short distance. These signals can be coded. For example it is a transmitter and a receiver infrared type of the type used in remote controls televisions. It can also be organs such as those used for opening to distance from gates, or central locking of vehicle doors. We could also use optical type organs, with emitting organ of light and a photocell. We could also use circuits more complex, for example of the resonant type or circuits using a field magnetic which is disturbed by introducing an element into the covered field stranger from the other retainer.

La figure 20 représente un premier schéma fonctionnel de commande qui peut être mis en oeuvre. Pour simplifier la compréhension, on convient que les organes émetteur et récepteur mis en oeuvre sont de type simple, c'est-à-dire avec un organe émetteur prévu pour émettre un signal, et un récepteur prévu pour capter le signal de l'émetteur.FIG. 20 represents a first functional control diagram which can be implemented. To simplify understanding, it is agreed that the transmitter and receiver elements used are of simple type, that is to say with an emitting member intended to emit a signal, and a receiver intended to emit receive the signal from the transmitter.

Le schéma comprend un interrupteur 100 qui réagit à la présence et l'absence de la chaussure, par exemple avec l'engagement de la chaussure et de sa libération. Par exemple, la plaque d'appui est construite comme la plaque précédente, avec une partie mobile 101. L'interrupteur 100 est placé sous l'extrémité mobile de la plaque.The diagram includes a switch 100 which reacts to the presence and the absence of the shoe, for example with the engagement of the shoe and his release. For example, the backing plate is constructed like the plate previous, with a movable part 101. The switch 100 is placed under the movable end of the plate.

L'interrupteur alimente les deux émetteurs, 103 et 104 et les deux récepteurs 105 et 106. Les deux récepteurs 105 et 106 sont par ailleurs couplés à un discriminateur 110 qui détermine lequel des récepteurs 105 ou 106 est activé par une émission de signaux en provenance de l'autre élément de retenue.The switch powers the two transmitters, 103 and 104 and the two receivers 105 and 106. The two receivers 105 and 106 are also coupled to a discriminator 110 which determines which of the receivers 105 or 106 is activated by a transmission of signals from the other retaining element.

Selon que le récepteur activé est le récepteur droit ou gauche de l'élément de retenue, le discriminateur commande la rotation du moteur 96 et de la bague 94 pour l'amener dans la position de polarisation appropriée.Depending on whether the activated receiver is the right or left receiver of the element retained, the discriminator controls the rotation of the motor 96 and of the ring 94 to bring it into the appropriate polarization position.

Lorsque l'interrupteur 100 n'est plus activé par la chaussure, l'émission de signaux cesse. On peut prévoir dans ce cas que le discriminateur ramène la bague en position médiane, de façon qu'elle soit prête pour un nouveau chaussage. Ceci n'est cependant pas essentiel.When the switch 100 is no longer activated by the shoe, the emission of signals cease. In this case, it can be provided that the discriminator brings the ring back in the middle position, so that it is ready for a new fitting. This is not essential, however.

La figure 21 illustre une variante de mise en oeuvre du schéma fonctionnel. Selon cette variante, l'interrupteur 100 est coupé à un circuit de temporisation 115 qui active les deux émetteurs 103 et 104 et les récepteurs 105 et 106 pendant une durée de temps déterminée, par exemple une durée d'une ou deux minutes après l'engagement de la chaussure.FIG. 21 illustrates a variant implementation of the functional diagram. According to this variant, the switch 100 is cut to a timing circuit 115 which activates the two transmitters 103 and 104 and the receivers 105 and 106 during a fixed duration of time, for example a duration of one or two minutes after the engagement of the shoe.

Comme dans le cas précédent un discriminateur 120 est couplé aux deux récepteurs. Toutefois, il a ici pour seule fonction de piloter la mise en position correcte de la bague en fonction du récepteur activé pendant la durée de temps déterminée.As in the previous case a discriminator 120 is coupled to the two receivers. However, its sole function here is to control the positioning correct ring according to the activated receiver for the duration of time determined.

Le circuit présente en effet de façon préférentielle un circuit de remise à zéro 121 qui est couplé au circuit de temporisation 115, dont la fonction est de ramener la bague en position médiane lorsque la chaussure est libérée. The circuit preferably has a reset circuit 121 which is coupled to the timing circuit 115, whose function is to bring back the ring in the middle position when the shoe is released.

De préférence également, un second interrupteur 122 est placé de façon accessible. Par exemple, il est prévu à la surface supérieure du capot, pour pouvoir être manoeuvré par le bâton de ski. Cet interrupteur est placé en parallèle sur l'interrupteur 100, et sa fonction est de réactiver volontairement le circuit de temporisation pendant la période de temps déterminée. Cet interrupteur sera notamment utilisé en cas de rechaussage de l'autre ski après une libération accidentelle de la chaussure, de façon à émettre des signaux qui vont permettre à l'autre élément de retenue de se polariser de nouveau. En effet, le circuit de remise à zéro 121 de cet élément de retenue aura rappelé la bague en position médiane à la libération de la chaussure.Also preferably, a second switch 122 is placed so accessible. For example, it is provided on the upper surface of the hood, to be able to be maneuvered by the ski pole. This switch is placed in parallel on switch 100, and its function is to reactivate the circuit voluntarily time delay during the determined period of time. This switch will in particular used in the event of upgrading of the other ski after a release accidental of the shoe, so as to emit signals which will allow the other retainer to polarize again. Indeed, the delivery circuit at zero 121 of this retaining element will have recalled the ring in the middle position at the release of the shoe.

Ces schémas fonctionnels ne sont donnés qu'à titre indicatif, ils n'ont pas de valeur limitative en regard de l'invention. Il existe en effet d'autres possibilités.These functional diagrams are given for information only, they have no limiting value with regard to the invention. There are indeed other possibilities.

La figure 22 illustre une variante de mise en oeuvre. Les émetteurs et les récepteurs sont ici remplacés par un simple interrupteur.FIG. 22 illustrates an alternative implementation. Issuers and receivers are replaced here by a simple switch.

Ainsi, la figure représente deux éléments de retenue 123' et 123'' disposés côte à côte. Chaque élément présente de chaque côté un interrupteur 124', 125', 124'', 125'', dont la partie mobile traverse la paroi latérale du capot. A l'extérieur du capot de l'élément de retenue, la partie mobile de l'interrupteur est protégée par une paroi en caoutchouc en forme de bulle 126', 127', 126'', 127''. Ceci n'est cependant pas essentiel, et tout autre moyen approprié convient.Thus, the figure represents two retaining elements 123 'and 123' 'arranged side by side. Each element has a switch 124 ′, 125 ′ on each side, 124 '', 125 '', the movable part of which crosses the side wall of the hood. Outside the cover of the retaining element, the moving part of the switch is protected by a bubble-shaped rubber wall 126 ', 127', 126 '', 127 ''. This is not however not essential, and any other suitable means is suitable.

Le principe de fonctionnement de cette variante de réalisation est le suivant. Au moment du chaussage, le skieur actionne l'interrupteur intérieur de chaque élément de retenue avec un organe de l'autre ski, c'est-à-dire par exemple le ski lui-même, la chaussure, l'élément de retenue ou l'autre interrupteur intérieur.The operating principle of this alternative embodiment is as follows. At the time of putting on, the skier actuates the interior switch of each retainer with a member of the other ski, i.e. for example the ski itself, the shoe, the retainer or the other interior switch.

En aval, un circuit discriminateur 129 détecte lequel des deux interrupteurs a été actionné, et commande le moteur 96 de façon à amener la bague 94 dans la position de polarisation correspondant à la position droite ou gauche de l'élément de retenue.Downstream, a discriminator circuit 129 detects which of the two switches has been actuated, and controls the motor 96 so as to bring the ring 94 into the polarization position corresponding to the right or left position of the element of restraint.

Pour éviter que ce réglage soit modifié au cours de la pratique du ski , on peut prévoir un circuit de temporisation 130 commandé par un interrupteur 131 sensible à l'engagement et à la libération de la chaussure. Le circuit de temporisation active le discriminateur pendant une durée de temps déterminée après l'engagement de la chaussure. Après cette durée au cours de laquelle le skieur est sensé réaliser les manoeuvres nécessaires à la polarisation de ses éléments de retenue, le circuit 130 neutralise le discriminateur jusqu'à ce que la chaussure soit libérée. A la libération de la chaussure, on peut prévoir que le circuit de temporisation et le discriminateur commandent le moteur en retour à sa position médiane.To prevent this setting from being changed during skiing, you can provide a timing circuit 130 controlled by a sensitive switch 131 the engagement and release of the shoe. The active delay circuit the discriminator for a specified period of time after the engagement of the shoe. After this period during which the skier is supposed to perform the maneuvers necessary for the polarization of its retaining elements, the circuit 130 neutralizes the discriminator until the shoe is released. To the release of the boot, provision can be made for the timing circuit and the discriminator control the motor back to its middle position.

Comme pour le cas précédent, d'autres modes de fonctionnement sont également possibles. Ce qui importe ici, c'est que les éléments de retenue sont polarisés par un mouvement naturel qui dépend directement de la position que les élément occupent aux pieds du skieurs.As in the previous case, other operating modes are also possible. What matters here is that the retainers are polarized by a natural movement which depends directly on the position that the element occupy at the feet of the skiers.

De plus, l'invention n'est pas non plus limitée aux constructions mécaniques qui ont été décrites, de nombreuses variantes existent, selon que la mâchoire présente deux ailes indépendantes, ou deux ailes dont le mouvement latéral est lié, ou selon que le corps de l'élément de retenue est fixe sur le ski ou mobile avec la mâchoire.In addition, the invention is also not limited to mechanical constructions which have been described, many variants exist, depending on whether the jaw has two independent wings, or two wings whose lateral movement is linked, or depending on whether the body of the retaining element is fixed on the ski or mobile with jaw.

  1. Assembly of two elements for retaining the two boots of a skier on two skis, each retention element having:
    a retention jaw (7, 8, 77, 78) adapted to retain one end of the boot, the jaw being movable at least in a horizontal plane on one side and the other from a central position where it is aligned with the longitudinal median plane defined by this ski;
    a spring (12, 82) for returning the jaw to its aligned position;
    a linkage (7a, 8a) for transmission of movement between the retention jaw and the spring which compresses the spring with the spacing movement of the jaw with respect to its aligned position, from one side or the other of its aligned position, and which sends back to the jaw an elastic return force towards its aligned position;
    the jaw and the spring being adapted to free the end of the boot beyond a predetermined release threshold corresponding to a predetermined amplitude of displacement of the jaw and to a predetermined extend of compression of the spring;
       characterized in that it has
    an adjustment mechanism (25, 24, 96, 97) acting on the transmission linkage to modify in a differential manner the release threshold of the jaw depending upon whether it is displaced to one side or the other with respect to its aligned position;
    a manipulation element (35', 35'', 61, 105', 105'', 123', 123'', 124', 124'') adapted to be activated from the other retention element and to control the adjustment mechanism.
  2. Assembly according to claim 1, characterized in that the two elements are constructed in an identical manner.
  3. Assembly according to claim 1, characterized in that it has a latch (38) provided to block in a releasable manner the adjustment mechanism.
  4. Assembly according to claim 3, characterized in that it has an elastic element (37a, 37b) for returning the adjustment mechanism (24) to the median position.
  5. Assembly according to claim 1, characterised in that for each of the retention elements, the manipulation element is a magnetized bar (35) oriented along a transverse direction, and guided by a translational movement along this transverse direction,
  6. Assembly according to claim 5, characterized in that the magnetized bar (35) is engaged on a ring (24) the rotation of which it controls by virtue of its displacement in translation.
  7. Assembly according to claim 5, characterized in that the cap (3) of each retention element has at least one window (48, 49) positioned along the path of displacement of the bar.
  8. Assembly according to claim 1, characterized in that each element has a transverse cursor (61) whose two ends project from each side of the wall of the retention element.
  9. Assembly according to claim 8, characterized in that the cursor (61) is connected to the end of a lever journalled about a fixed axis.
  10. Assembly according to claim 8, characterized in that the other end of the lever is connected to a rack (55) oriented along a transverse direction, and guided for a translational movement along this transverse direction.
  11. Assembly according to claim 1, characterized in that the adjustment mechanism comprises an electric motor (96).
  12. Assembly according to claim 11, characterized in that the manipulation element comprises for each retention element two signal transmitters (103, 104), and two signal receivers (105, 106), a transmitter and a receiver being placed on each side of the retention element.
  13. Assembly according to claim 12, characterized in that the two receivers (104, 105) are coupled to a discriminator (110) provided to determine which of the two receivers (104, 105) is activated by one of the transmitters of the other retention element.
  14. Assembly according to claim 1, characterized in that the manipulation element comprises for each retention element two interrupters (123', 123'', 124', 124''), one on each side, whose movable portion projects so as to be accessible from the other retention element.
