Description

La présente invention concerne un dispositif de retenue d'une chaussure sur une planche de glisse.The present invention relates to a device for retaining a boot on a gliding board.

Un tel dispositif de retenue est connu du document FR 2 775 613 . Ce dispositif, comporte un élément de retenue avant non déclenchable automatiquement et un élément de retenue arrière non déclenchable automatiquement. Un tel dispositif offre une sécurité optimale pour les planches de glisse de petite taille. En revanche, il peut être souhaitable lorsqu'on utilise des planches de glisse de taille plus importante, que le dispositif de retenue comporte des moyens de déclenchement de sécurité automatique qui libèreront la chaussure en fonction des efforts auxquels cette dernière est soumise.Such a retainer is known from the document FR 2,775,613 . This device comprises an automatically non-releasable front retaining element and an automatically non-releasable rear retaining element. Such a device offers optimum safety for small gliding boards. On the other hand, it may be desirable when using larger gliding boards, that the retaining device comprises automatic safety release means which will release the boot as a function of the forces to which it is subjected.

Pour répondre à ce problème, le document CH 666624 propose de fixer un élément de retenue avant non déclenchable et un élément de retenue arrière non déclenchable, de type « step-in », sur une plaque, laquelle est montée de façon « déclenchable » sur la planche de glisse. Les moyens de déclenchement de sécurité consistent en un « élément de talon » (Fersenelement), lequel contient un ressort. Pendant une phase de ski, lorsque les efforts auxquels est soumise la plaque sont tels qu'ils génèrent une contraction suffisante du ressort, la plaque est libérée. Un tel dispositif n'est pas entièrement satisfaisant dans la mesure où lorsque le déclenchement de sécurité se produit, la plaque reste solidaire de la chaussure et il faut qu'après le déclenchement de sécurité, l'utilisateur retire la chaussure des éléments de retenue avant et arrière. L'utilisation d'un tel dispositif se révèle compliqué et peu intuitif. D'autre part, ce dispositif n'offre pas une sécurité suffisante. En effet, le déclenchement se faisant contre la force d'un seul ressort lequel étant placé selon un axe parallèle au ski, un tel dispositif ne pourra réagir de façon adéquate aux efforts qui s'exercent suivant toutes les directions. De plus, dans un dispositif tel que celui-ci, on peut difficilement adapter ou modifier le seuil de déclenchement. En général, il est prévu la possibilité de changer la précontrainte du ressort pour faire varier l'unique seuil de déclenchement, mais il est impossible de faire varier indépendamment des autres, plusieurs seuils de déclenchement, par exemple dans le cas où le seuil déclenchement latéral est plus faible que le seuil de déclenchement vertical. Enfin, un tel dispositif de retenue ne permet que de faire dépendre le seuil de déclenchement des efforts instantanés auxquels la chaussure est soumise. En aucun cas on pourra permettre un déclenchement qui dépendrait du temps d'application desdits efforts.To address this problem, the document CH 666624 proposes to attach a non-releasable front retaining element and a non-releasable, step-in rear retaining element to a plate, which is "triggered" on the gliding board. The safety release means consist of a "heel element" (Fersenelement), which contains a spring. During a ski phase, when the forces to which the plate is subjected are such that they generate a sufficient contraction of the spring, the plate is released. Such a device is not entirely satisfactory insofar as when the safety release occurs, the plate remains secured to the boot and it is necessary that after the safety release, the user removes the shoe from the front retainers. and back. The use of such a device is complicated and not very intuitive. On the other hand, this device does not provide sufficient security. Indeed, the trigger being against the force of a single spring which is placed along an axis parallel to the ski, such a device can not react adequately to the forces exerted in all directions. Moreover, in a device such as this one can hardly adapt or modify the triggering threshold. In general, provision is made for the possibility of changing the preload of the spring to vary the single triggering threshold, but it is impossible to vary independently of the others, several triggering thresholds, for example in the case where the lateral triggering threshold is lower than the vertical trigger. Finally, such a retaining device only makes it possible to make the trigger threshold depend on the instantaneous forces to which the boot is subjected. In no case can one allow a trigger that depends on the time of application of said efforts.

L'invention a pour objet de fournir un dispositif de retenue d'une chaussure sur une planche de glisse, dont le fonctionnement est amélioré par rapport aux dispositifs de l'art antérieur. Notamment, l'invention a pour objet de fournir un dispositif de retenue de sécurité d'une chaussure sur une planche de glisse permettant un comportement simple et intuitif.The object of the invention is to provide a device for retaining a boot on a gliding board, the operation of which is improved with respect to the devices of the prior art. In particular, the object of the invention is to provide a device for retaining the safety of a boot on a gliding board allowing a simple and intuitive behavior.

L'invention a également pour objectif de fournir un dispositif de retenue qui permet une très grande adaptabilité de la loi définissant le seuil de déclenchement en fonction du temps d'application des efforts.The invention also aims to provide a retaining device that allows a very high adaptability of the law defining the trigger threshold as a function of the time of application of forces.

On pourrait également dire que le mouvement de translation de la platine est libéré en fonction des valeurs fournies par lesdits moyens de mesure. Cette libération prenant place grâce à des moyens d'actionnement.The object of the invention is achieved by providing a device for retaining a boot on a gliding board comprising a non-releasable front retaining element and a non-releasable rear retaining element and means for measuring the forces to which said shoe is subjected when it is fastened to said retainer, characterized in that at least one of said front retaining element and rear retaining element is fixed on a plate animated with a translational movement and in that said translation movement is controlled according to the values provided by said measuring means.

Les valeurs mesurées sont traitées par un circuit électronique de commande, qui permet de prendre en compte le temps d'application des efforts à la prise de décision du déclenchement. De plus la loi de déclenchement pourra être adaptée et mise à jour en fonction des utilisateurs ou de l'avancée des connaissances en traumatologie des accidents de ski.The triggering device of the retaining device according to the invention uses measuring means, such as strain gauges which make it possible to accurately measure the forces that are transmitted between the shoe and the gliding board in all directions.

L'élément de retenue avant 2 est constitué par un étrier avant 33. Ce dernier est réalisé en fil d'acier coudé en différents endroits de façon à définir différents segments. Parmi ces segments, on trouve le segment de retenue 35 qui est destiné à venir au contact de l'embout avant de la chaussure ainsi que les segments pivot 36 qui sont logés dans une ouverture correspondante de l'embase avant 37 de l'élément de retenue avant 2, de façon à permettre la rotation de l'étrier avant 33 autour desdits segments pivots 36.The front retaining element 2 consists of a front caliper 33. The latter is made of bent steel wire in different places so as to define different segments. Among these segments, there is the retaining segment 35 which is intended to come into contact with the front end of the shoe as well as the pivot segments 36 which are housed in a corresponding opening of the front base 37 of the element of retained before 2, so as to allow the rotation of the front stirrup 33 around said pivot segments 36.

L'élément de retenue arrière 3 est constitué par un étrier arrière 34, également réalisé en fil d'acier coudé en différents endroits de façon à définir différents segments. Parmi ces segments, on trouve le segment d'actionnement 38 sur lequel est monté pivotant un levier 39, ainsi que les segments pivot 36 qui sont logés dans une ouverture correspondante de l'embase arrière 40 de l'élément de retenue arrière 3.The rear retaining element 3 is constituted by a rear caliper 34, also made of steel wire bent at different locations so as to define different segments. Among these segments, there is the actuating segment 38 on which is pivotally mounted a lever 39, as well as the pivot segments 36 which are housed in a corresponding opening of the rear base 40 of the rear retaining element 3.

Le levier 39 comprend une partie basse appelée talon 41 qui vient se caler contre l'embout arrière 62 de la chaussure 20 et une poignée d'actionnement 42.The lever 39 comprises a lower part called heel 41 which is wedged against the rear end 62 of the shoe 20 and an actuating handle 42.

Lors de la fixation de la chaussure dans le dispositif de retenue, l'utilisateur vient poser son pied, chaussé, sur les éléments de retenue avant et arrière tout en glissant l'avant de la chaussure sous l'étrier avant. Ensuite, prenant le levier 39 en main, il vient poser le talon 41 du levier 39 sur l'embout arrière de la chaussure et bascule le levier contre la tige de la chaussure. L'élément de retenue avant 2 comme l'élément de retenue arrière 3 sont dit non-déclenchables dans la mesure où pour désolidariser la chaussure des éléments de retenue, il est nécessaire de manoeuvrer à nouveau le levier dans le sens opposé et en aucun cas, quels que soient les efforts auxquels, ces derniers sont soumis, il y aura un déclenchement, c'est-à-dire une ouverture automatique, des éléments de retenue.When fixing the boot in the retainer, the user comes to put his foot, shod, on the front and rear retainers while sliding the front of the shoe under the front caliper. Then, taking the lever 39 in hand, he just put the heel 41 of the lever 39 on the rear end of the shoe and tilts the lever against the upper of the shoe. The front retaining element 2 and the rear retaining element 3 are said to be non-releasable insofar as, in order to separate the boot from the retaining elements, it is necessary to move the lever again in the opposite direction and in no case regardless of the forces to which they are subjected, there will be a trigger, that is to say an automatic opening, retaining elements.

L'élément de retenue arrière 3, est fixé sur une platine 43 pouvant coulisser dans une glissière 7.The rear retention element 3 is fixed on a plate 43 slidable in a slideway 7.

L'élément de retenue avant 2, est fixé sur un élément d'interface avant 5, lequel est fixé sur le ski 1.The front retention element 2 is fixed on a front interface element 5, which is fixed on the ski 1.

L'élément de retenue arrière 3 comprend une glissière 7 dans laquelle le corps de l'élément de retenue arrière 3 peut coulisser.The rear retaining element 3 comprises a slideway 7 in which the body of the rear retaining element 3 can slide.

Le dispositif de déclenchement 4 comprend un boîtier actionneur 8, un boîtier de commande 9 et un capteur avant 11, respectivement arrière 12, placés dans l'élément d'interface avant 5, respectivement l'élément d'interface arrière 6.The trigger device 4 comprises an actuator box 8, a control unit 9 and a front sensor 11, respectively rear 12, placed in the front interface element 5, respectively the rear interface element 6.

Le boîtier de commande 9 comprend un circuit électronique et un dispositif d'interface homme/machine incluant un afficheur.The control box 9 comprises an electronic circuit and a man / machine interface device including a display.

Le boîtier actionneur 8 est relié au corps de l'élément de retenue arrière par une tringle 10 susceptible de se déplacer longitudinalement en entraînant la platine 43, laquelle coulisse dans la glissière 7.The actuator housing 8 is connected to the body of the rear retention element by a rod 10 capable of moving longitudinally by driving the plate 43, which slides in the slideway 7.

Les capteurs avant 11 et arrière 12 mesurent en permanence les efforts auxquels ils sont soumis et transmettent ces valeurs au boîtier de commande. Le traitement de ces valeurs en fonction d'une loi de déclenchement conduit le circuit électronique du boîtier de commande à générer un ordre d'actionnement de la tringle 10, laquelle éloigne la platine 43, et par conséquent, l'élément de retenue arrière 3, de l'élément de retenue avant 2, ce qui libère la chaussure.The front 11 and rear 12 sensors continuously measure the forces to which they are subjected and transmit these values to the control box. The treatment of these values as a function of a tripping law causes the electronic circuit of the control box to generate an order of actuation of the rod 10, which removes the plate 43, and consequently the rear retention element 3 of the front retention element 2, which releases the shoe.

Les efforts mesurés par les capteurs avant 11 et arrière 12 sont représentatifs des efforts auxquels sont soumis la jambe et le pied de l'utilisateur. Une loi de déclenchement simple peut se contenter de reproduire le fonctionnement d'une fixation de sécurité traditionnelle mécanique, c'est-à-dire une fixation de sécurité dans laquelle le déclenchement se fait contre la force d'un ressort. Dans une telle loi de déclenchement, lorsque les efforts mesurés par le capteur avant 11 ou le capteur arrière 12 dépassent un certain seuil, l'ordre d'actionnement de la tringle est donné. Bien entendu, l'invention ne se limite pas à une telle loi de déclenchement, et toute autre loi de déclenchement est applicable dans le cadre de l'invention. Pour n'en citer que quelques unes, des lois de déclenchement, dans lesquelles il sera tenu compte du temps d'application des efforts, ou des angles de flexion du genou sont également envisageables dans le cadre de l'invention.The forces measured by the front 11 and rear 12 sensors are representative of the forces to which the user's leg and foot are subjected. A simple triggering law can be content to reproduce the operation of a traditional mechanical safety fastener, that is to say a safety fastener in which the release is against the force of a spring. In such a tripping law, when the forces measured by the front sensor 11 or the rear sensor 12 exceed a certain threshold, the order actuating the rod is given. Of course, the invention is not limited to such a triggering law, and any other triggering law is applicable in the context of the invention. To name but a few, triggering laws, in which account will be taken of the time of application of the forces, or knee flexion angles are also conceivable within the scope of the invention.

La présence d'un capteur à l'avant et d'un autre à l'arrière n'est pas une caractéristique limitative de l'invention. En effet, il est également possible de n'avoir qu'un seul capteur.The presence of a sensor at the front and another at the rear is not a limiting feature of the invention. Indeed, it is also possible to have only one sensor.

La figure 2 montre en vue de côté, un autre mode de réalisation de l'invention. L'élément de retenue avant 2 est constitué d'un serre-semelle 44 fixé sur une embase avant 37. Le serre-semelle 44 comprend une portion en saillie destinée à prendre appui sur l'embout avant 61 de la chaussure 20 de ski. L'élément de retenue avant 2 comprend également une plaque d'appui 45 pouvant coulisser transversalement. La fixation du serre-semelle 44 sur l'embase avant 37 est telle qu'il possède une certaine laxité latérale et verticale. Cette double laxité est énergisée et élastique par l'utilisation de ressort ou de silentbloc, c'est-à-dire de pièce en caoutchouc ou en matériau équivalent.The figure 2 shows in side view, another embodiment of the invention. The front retention element 2 consists of a sole clamp 44 fixed on a front base 37. The sole clamp 44 comprises a projecting portion intended to bear on the front end 61 of the ski boot 20. The front retention element 2 also comprises a support plate 45 which can slide transversely. Fixing the sole clamp 44 on the front base 37 is such that it has a certain lateral and vertical laxity. This double laxity is energized and elastic by the use of spring or silentbloc, that is to say of rubber part or equivalent material.

La figure 2a décrit une vue partielle de dessus du serre-semelle 44. Ce dernier est fixé sur l'embase avant 37 par l'intermédiaire d'une vis de fixation 63. Le serre-semelle peut pivoter suivant l'axe de la vis de fixation autour d'une position centrale. Ce mouvement de pivot est limité angulairement. Dans le mouvement de pivot, le serre-semelle 44 vient comprimer le bloc d'élastomère 64 qui se trouve dans un logement ménagé dans le serre-semelle et au contact de la vis de fixation.The figure 2a describes a partial top view of the sole clamp 44. The latter is fixed on the front base 37 by means of a fixing screw 63. The clamp can be rotated along the axis of the fixing screw around from a central position. This pivot movement is angularly limited. In the pivoting movement, the sole clamp 44 compresses the elastomer block 64 which is in a housing formed in the sole clamp and in contact with the fixing screw.

L'élasticité latérale est utilisée pour amortir les chocs en latéral et améliore le confort d'utilisation et la skiabilité par une meilleure tolérance du dispositif de retenue.Lateral elasticity is used to cushion shocks in the side and improves the comfort of use and the skiability by a better tolerance of the restraint.

L'élasticité verticale est utilisée pour permettre une adaptation de l'élément de retenue avant 2 à des chaussures dont les embouts avant ont des hauteurs différentes ainsi qu'à compenser l'apparition d'une éventuelle cale de neige entre la plaque d'appui et le dessous de la semelle.The vertical elasticity is used to allow an adaptation of the front retainer 2 to shoes whose front ends have different heights and to compensate for the appearance of a possible wedge of snow between the backing plate and the underside of the sole.

On pourra prévoir des moyens d'adaptation de l'élasticité de façon à améliorer la performance sur neige.Elasticity adaptation means may be provided to improve snow performance.

L'élément de retenue arrière 3 est constitué par une talonnière « Step-in » 46. La talonnière 46 est fixée sur une platine 43 par l'intermédiaire d'un cavalier 47, lui-même fixé par vis dans les flancs de la platine 43. Des ouvertures oblongues 48 sont ménagées dans le socle 49 de la talonnière 46 de façon à permettre l'adaptation du dispositif aux différentes longueurs de chaussure.The rear retention element 3 is constituted by a step-in heel 46. The heel 46 is fixed on a plate 43 by means of a rider 47, itself fixed by screws in the flanks of the plate. 43. Oblong openings 48 are formed in the base 49 of the heel 46 so as to allow the adaptation of the device to the different shoe lengths.

La figure 4 décrit en coupe longitudinale la talonnière 46 en position fermée. Elle comprend un levier 39 monté pivotant sur le socle 49 autour d'un premier axe 50 et une mâchoire 53 montée, pivotante, sur le socle 49 autour d'un deuxième axe 51. Une pédale 52 est montée pivotante sur la mâchoire 53 autour d'un troisième axe 54, mais ne dispose que d'un angle de rotation très faible par rapport à celle-ci. Entre la pédale 52 et le levier 39 sont disposés deux ressorts de torsion 55, identiques, et placés symétriquement par rapport à l'axe longitudinal du ski. L'un de ces ressorts 55 est visible à la figure 4. Ces ressorts 55 sont constitués d'un fil métallique entouré autour du premier axe 50 dont la première des extrémités fixée à la mâchoire 53 tandis que l'autre est mise en pression contre un ergot 56 de la pédale 52.The figure 4 described in longitudinal section the heel 46 in the closed position. It comprises a lever 39 pivotally mounted on the base 49 around a first axis 50 and a jaw 53 pivotally mounted on the base 49 around a second axis 51. A pedal 52 is pivotally mounted on the jaw 53 around the center of the jaw 53. a third axis 54, but has only a very small angle of rotation relative thereto. Between the pedal 52 and the lever 39 are arranged two torsion springs 55, identical, and placed symmetrically with respect to the longitudinal axis of the ski. One of these springs 55 is visible at the figure 4 . These springs 55 consist of a wire wrapped around the first axis 50 whose first end is attached to the jaw 53 while the other is pressurized against a lug 56 of the pedal 52.

Les ressorts 55 ont pour rôle de fournir l'énergie nécessaire à un chaussage automatique de la chaussure dans la fixation de ski. En effet, lorsque l'utilisateur vient placer son pied, chaussé dans une chaussure de ski, dans le dispositif de retenue, il place l'extrémité avant de la chaussure, porteuse de l'embout avant, dans le serre semelle 44. Puis, par un mouvement de bascule, il vient poser l'arrière de la chaussure 20 dans la talonnière 46, laquelle se trouve alors dans la configuration décrite à la figure 4. La talon de la chaussure se pose puis exerce une pression sur la pédale 52. Dans sons mouvement de rotation vers le bas, elle entraîne la mâchoire. L'énergie accumulée dans les ressorts 55 a alors une double fonction. D'une part, elle accentue le mouvement de pivot de la mâchoire 53, d'autre part elle entraîne le levier 39 dans un mouvement de rotation vers le haut, jusqu'à ce qu'une première butée 57 placée sur le levier vienne en appui contre une seconde butée 58 de la mâchoire. La chaussure est alors fermement retenue entre le serre-semelle et la talonnière 46. Tant qu'il y a engagement mécanique entre la première butée 57 du levier et de la deuxième butée 58 de la mâchoire, il ne peut y avoir d'ouverture de la talonnière « step-in », et ce quels que soient les efforts auxquels sont soumis les éléments de retenue, c'est-à-dire quels que soient les efforts auxquels est soumise la jambe du skieur. Pour ouvrir la talonnière « Step in » et libérer la chaussure il faut basculer le levier 39 en arrière depuis la position qu'il occupe à la figure 2, de façon à désengager mécaniquement levier et mâchoire.The springs 55 have the role of providing the energy necessary for an automatic boot of the boot in the ski binding. Indeed, when the user comes to place his foot, shod in a ski boot, in the retainer, he places the front end of the shoe, carrying the front end, in the greenhouse sole 44. Then, by a flip-flop movement, it comes to rest the back of the shoe 20 in the heel piece 46, which is then in the configuration described in FIG. figure 4 . The heel of the shoe arises then exerts pressure on the pedal 52. In its downward rotational movement, it drives the jaw. The energy accumulated in the springs 55 then has a dual function. On the one hand, it accentuates the pivoting movement of the jaw 53, on the other hand it drives the lever 39 in an upward rotational movement, until a first stop 57 placed on the lever comes into position. bearing against a second stop 58 of the jaw. The shoe is then firmly retained between the sole clamp and the heel piece 46. As long as there is mechanical engagement between the first stop 57 of the lever and the second stop 58 of the jaw, there can be no opening of the step-in heel, regardless of the forces to which the restraining elements are subjected, that is to say whatever the forces to which the skier's leg is subjected. To open the heel "Step in" and release the shoe must switch lever 39 back from the position it occupies the figure 2 , so as to disengage mechanically lever and jaw.

Le déclenchement de sécurité est réalisé par l'intermédiaire d'un dispositif de déclenchement similaire à celui qui a été décrit à la figure 1, et dont la description ne sera pas reprise en détail dans ce paragraphe.The safety release is performed by means of a trigger device similar to that described in figure 1 , and the description of which will not be repeated in detail in this paragraph.

La figure 3 décrit le mode de réalisation de la figure 2 après que celui-ci a déclenché et libéré la chaussure 20. Pour effectuer le déclenchement, le boîtier actionneur 8 libère la tringle 10 et l'élément de retenue arrière peut coulisser vers l'arrière. Le boîtier actionneur 8 comprend un moteur rotatif, un électro-aimant ou tout autre moyen d'actionnement. Le détail du fonctionnement du boîtier actionneur 8 sera expliqué plus loin dans le texte. Il est important de noter que même après que le dispositif de retenue a déclenché, la talonnière step-in est toujours en position fermée. C'est simplement parce que la distance qui la sépare du serre-semelle a augmenté que la chaussure a pu être libérée. Pour pouvoir, chausser à nouveau, l'utilisateur devra actionner le levier 39 pour réarmer la talonnière step-in.The figure 3 describes the embodiment of the figure 2 after it has triggered and released the shoe 20. To perform the trigger, the actuator housing 8 releases the rod 10 and the rear retainer can slide back. The actuator housing 8 comprises a rotary motor, an electromagnet or any other actuating means. The detail of the operation of the actuator housing 8 will be explained later in the text. It is important to note that even after the restraint has tripped, the heel step-in is still in the closed position. It is simply because the distance to the sole clamp has increased that the shoe has been released. To be able to put on again, the user will have to operate the lever 39 to rearm the heel step-in.

La figure 5 décrit un autre mode de réalisation de l'invention qui diffère du mode de réalisation précédent en ce que l'élément de retenue avant est constitué par un étrier avant 33. Ce dernier est réalisé en fil d'acier coudé en différents endroits de façon à définir différents segments. Parmi ces segments, on trouve le segment de retenue 35 qui est destiné à venir au contact de l'embout avant de la chaussure ainsi que les segments pivot 36 qui sont logés dans une ouverture correspondante de l'embase avant 37 de l'élément de retenue avant 2, de façon à permettre la rotation de l'étrier avant 33 autour desdits segments pivots 36.The figure 5 describes another embodiment of the invention which differs from the previous embodiment in that the front retention element is constituted by a front caliper 33. The latter is made of bent steel wire in different places so as to define different segments. Among these segments, there is the retaining segment 35 which is intended to come to the contact of the front end of the shoe and the pivot segments 36 which are housed in a corresponding opening of the front base 37 of the front retention element 2, so as to allow the rotation of the front stirrup 33 around said pivot segments 36.

L'étrier avant 33 comporte en outre des segments de souplesse 59, lesquels sont au contact des flancs de l'embase avant 37.The front yoke 33 further comprises flexible segments 59, which are in contact with the flanks of the front base 37.

Comme on peut le voir sur la figure 5b, les flancs de l'embase avant 37 comportent des rampes 60 placées de part et d'autre de la position naturelle des segments de souplesse 59, laquelle est sensiblement verticale. Au-delà et en deçà de cette position naturelle les segments de souplesse 59 peuvent légèrement pivoter et glisser sur les rampes 60. Le glissement des segments de souplesse 59 sur les rampes impose une déformation élastique de l'étrier. C'est cette déformation qui donne l'énergie du mouvement de retour de l'étrier dans sa position naturelle verticale.As can be seen on the figure 5b , the flanks of the front base 37 comprise ramps 60 placed on either side of the natural position of the segments of flexibility 59, which is substantially vertical. Beyond and below this natural position the segments of flexibility 59 can slightly pivot and slide on the ramps 60. The sliding of the segments of flexibility 59 on the ramps imposes an elastic deformation of the stirrup. It is this deformation that gives the energy of the return movement of the stirrup in its natural vertical position.

Les figures 6 et 7 décrivent le boîtier actionneur 8 du dispositif d'actionnement en position "fermée" puis en position "ouverte".The Figures 6 and 7 describe the actuator housing 8 of the actuating device in the "closed" position and then in the "open" position.

Celui-ci comprend un bloc 13 recevant les différentes pièces constituant le boîtier actionneur 8. Le bloc 13 comprend un logement longitudinal dans lequel la tringle 10 peut pénétrer. A la fin de ce logement se trouve un puits vertical recevant un déclencheur 14.This comprises a block 13 receiving the various parts constituting the actuator housing 8. The block 13 comprises a longitudinal housing in which the rod 10 can penetrate. At the end of this housing is a vertical well receiving a trigger 14.

Le déclencheur 14 est un déclencheur rotatif. Sa partie supérieure comprend une encoche 15 et sa partie inférieure comprend une première roue dentée 16.The trigger 14 is a rotary trigger. Its upper part comprises a notch 15 and its lower part comprises a first toothed wheel 16.

Le moyen d'actionnement du dispositif de déclenchement est constitué par un moteur électrique 17 rotatif, dont l'arbre de sortie porte une deuxième roue dentée 18. L'alimentation du moteur se fait grâce à une pile électrique 19.The means for actuating the tripping device is constituted by a rotary electric motor 17 whose output shaft carries a second gear wheel 18. The motor is supplied by an electric battery 19.

Un pion cylindrique 21 est fixé à l'extrémité de la tringle 10. En position fermée, ce pion 21 est reçu dans l'encoche 15 du déclencheur 14.A cylindrical pin 21 is fixed to the end of the rod 10. In the closed position, this pin 21 is received in the notch 15 of the trigger 14.

Le dispositif de déclenchement est représenté à la figure 6 en position "fermée". Dans cette position le déclencheur 14 a une position angulaire telle que le pion 21 ne peut s'échapper de l'encoche 15. Lorsqu'on se trouve dans cette disposition, et que d'autre part, les éléments de retenue avant et arrière sont tous deux en position « en prise », la chaussure est solidaire de la planche de glisse. En fait, dans cette situation la chaussure ne peut être libérée que lorsque l'un ou l'autre, ou les deux, éléments de retenue avant et arrière passe de la position « en prise » à la position « libre ».The triggering device is represented at figure 6 in the "closed" position. In this position the trigger 14 has an angular position such that the pin 21 can not escape the notch 15. When in this arrangement, and secondly, the front and rear retainers are both in "engaged" position, the shoe is secured to the gliding board. In fact, in this situation the shoe can be released only when one or both of the front and rear retainers move from the "in" position to the "free" position.

Les capteurs avant 11, capteurs arrière 12 et le boîtier actionneur 8 sont reliés au boîtier de commande 9. A tout moment, les capteurs avant 11 et arrière 12 transmettent au boîtier de commande les contraintes auxquelles ils sont soumis. Le boîtier de commande 9 traite cette information et décide s'il y a lieu de relâcher la chaussure en ouvrant le dispositif de déclenchement 4.The front sensors 11, rear sensors 12 and the actuator box 8 are connected to the control box 9. At all times, the front 11 and rear 12 sensors transmit to the control box the stresses to which they are subjected. The control box 9 processes this information and decides whether to release the boot by opening the trigger device 4.

Dès que le boîtier de commande a décidé que la situation nécessite la libération de la chaussure, un ordre est passé au moteur 17, lequel se met en rotation. La rotation de la deuxième roue dentée 18 entraîne la rotation de la première roue dentée 16 avec laquelle elle est en prise. Le déclencheur 14 tourne d'un quart de tour et se retrouve dans la position décrite à la figure 7, c'est-à-dire de telle façon que l'encoche soit ouverte en direction de l'élément de retenue arrière 3. Dans cette position, le pion 21 n'est plus retenu et peut sortir de l'encoche 15. L'élément de retenue arrière 3 est par conséquent libre de coulisser vers l'arrière sous l'effet des efforts s'exerçant sur la chaussure, ce qui la libère.Once the control unit has decided that the situation requires the release of the shoe, an order is passed to the motor 17, which is rotated. The rotation of the second gear wheel 18 causes rotation of the first toothed wheel 16 with which it is engaged. The trigger 14 turns a quarter turn and is in the position described in the figure 7 , that is to say, such that the notch is open towards the rear retaining element 3. In this position, the pin 21 is no longer retained and can come out of the notch 15. L rear retaining member 3 is therefore free to slide back under the effect of the forces exerted on the shoe, which releases it.

Pour pouvoir rechausser, l'utilisateur doit réarmer le dispositif de déclenchement supplémentaire. Pour ce faire, il fait coulisser l'élément de retenue arrière 3 en direction de l'élément de retenue avant 2. La tringle 10 est également translatée dans cette même direction jusqu'à ce que le pion 21 vienne se loger dans l'encoche 15. Au moment où le pion 21 est dans l'encoche 15, la tringle actionne un contacteur 22 qui se trouve placé latéralement. Le contacteur 22 est à l'origine d'une nouvelle commande de mise en rotation du moteur électrique d'un quart de tour de telle façon que le déclencheur reprenne la position décrite à la figure 6, c'est-à-dire la position."fermée".To be able to retract, the user must reset the additional triggering device. To do this, it slides the rear retaining element 3 towards the front retaining element 2. The rod 10 is also translated in the same direction until the pin 21 comes to be housed in the notch 15. When the pin 21 is in the notch 15, the rod actuates a switch 22 which is placed laterally. The switch 22 is at the origin of a new command for rotating the electric motor a quarter of a turn so that the trigger returns to the position described in FIG. figure 6 that is, the "closed" position.

Les figures 8 et 9 décrivent le boîtier actionneur 8 selon un autre mode de réalisation de l'invention. Pour des raisons de simplicité, seules les pièces qui se distinguent du premier mode de réalisation seront décrites ici.The Figures 8 and 9 describe the actuator housing 8 according to another embodiment of the invention. For the sake of simplicity, only parts that differ from the first embodiment will be described here.

Le boîtier actionneur 8 comprend un bloc 13 qui reçoit les différentes pièces, et notamment un chariot 23 coulissant dans une direction longitudinale. Une platine 24 est montée dans le chariot et peut tourner autour d'un axe principal 28 orienté verticalement. A la base de cette platine 24 se trouve une première roue dentée 16, non visible sur les figures 8 et 9 car elle est cachée par la platine 24 qui a un diamètre plus important.The actuator housing 8 comprises a block 13 which receives the different parts, and in particular a carriage 23 sliding in a longitudinal direction. A plate 24 is mounted in the carriage and is rotatable about a main axis 28 oriented vertically. At the base of this plate 24 is a first toothed wheel 16, not visible on the Figures 8 and 9 because it is hidden by the plate 24 which has a larger diameter.

Un moteur électrique 17 est également fixé dans le chariot 23. Il comprend sur son arbre de sortie, orienté verticalement, une deuxième roue dentée 18 en prise avec la première roue dentée 16. Le moteur constitue le moyen d'actionnement rotatif de la platine, et on le verra plus loin, du dispositif de déclenchement.An electric motor 17 is also fixed in the carriage 23. It comprises on its output shaft, oriented vertically, a second gear 18 engaged with the first gear wheel 16. The motor constitutes the rotary actuating means of the plate, and will be seen later, the trigger device.

Une première biellette 25 est fixée dans une entaille inférieure 26 ménagée dans la platine 24. Cette première biellette 25 est montée rotative par la première de ses extrémités autour d'un premier axe secondaire orienté verticalement 27. La deuxième extrémité de la première biellette 25 est fixée sur le bloc. Par la rotation de la platine 24, le point d'attache de la première extrémité de la biellette 25 se déplace autour de l'axe principal 28 d'une distance égale au double de la distance séparant l'axe principal et le premier axe secondaire 27. Cela a pour effet le coulissement du chariot 23 dans le bloc 13.A first link 25 is fixed in a lower notch 26 formed in the plate 24. This first link 25 is rotatably mounted by the first of its ends around a first vertically oriented secondary axis 27. The second end of the first link 25 is fixed on the block. By the rotation of the plate 24, the point of attachment of the first end of the rod 25 moves around the main axis 28 by a distance equal to twice the distance separating the main axis and the first secondary axis 27. This has the effect of sliding the carriage 23 in the block 13.

La platine comprend également une entaille supérieure 29. La première extrémité d'une deuxième biellette 30 est montée rotative autour d'un deuxième axe secondaire 31 dans cette entaille supérieure 29.The plate also comprises an upper notch 29. The first end of a second link 30 is rotatably mounted about a second secondary axis 31 in this upper slot 29.

Le deuxième axe secondaire 31 est diamétralement opposé au premier axe secondaire 27 par rapport à l'axe principal.The second secondary axis 31 is diametrically opposed to the first secondary axis 27 with respect to the main axis.

La deuxième extrémité de la deuxième biellette 30 est fixée à la tringle 10 (non représentée sur cette figure), laquelle est comme pour le mode de réalisation précédent reliée au corps de l'élément de retenue arrière.The second end of the second link 30 is fixed to the rod 10 (not shown in this figure), which is as for the previous embodiment connected to the body of the rear retaining element.

La rotation de la platine 24, générée par le moteur entraîne le déplacement de la première extrémité de la deuxième biellette d'une distance égale au double de la distance séparant l'axe principal 28 du deuxième axe secondaire 31.The rotation of the plate 24, generated by the motor causes the displacement of the first end of the second rod by a distance equal to twice the distance separating the main axis 28 from the second secondary axis 31.

Le mécanisme représenté à la figure 8, l'est en position "fermée", c'est-à-dire lorsque l'élément de retenue arrière est contre la chaussure de ski. Dans cette position l'axe principal 28, le premier axe secondaire 27 et le deuxième axe secondaire 31 ne sont pas rigoureusement alignés. En effet le deuxième axe secondaire est légèrement au-delà de la position d'équilibre instable qu'il aurait si ces trois axes étaient alignés. Etant donné que l'élément de retenue arrière exerce au travers de la tringle 10 une force de traction sur la deuxième biellette, la platine 24 ne peut rester dans la disposition représentée à la figure 4 que dans la mesure où une butée 32, solidaire de la platine, stoppe la rotation de la platine 24 lorsque celle-ci est au contact de la deuxième biellette 30.The mechanism represented in figure 8 , is in the "closed" position, that is to say when the rear retaining element is against the ski boot. In this position the main axis 28, the first secondary axis 27 and the second secondary axis 31 are not strictly aligned. Indeed the second secondary axis is slightly beyond the unstable equilibrium position it would have if these three axes were aligned. Since the rear retaining element exerts through the rod 10 a traction force on the second link, the plate 24 can not remain in the arrangement shown in FIG. figure 4 that to the extent that a stop 32, integral with the plate, stops the rotation of the plate 24 when it is in contact with the second link 30.

Lorsqu'un ordre de déclenchement est fourni au boîtier d'actionnement par le boîtier de commande, le moyen d'actionnement rotatif du dispositif de déclenchement constitué par le moteur fait tourner la platine 24 suffisamment pour qu'elle dépasse le point d'équilibre instable constitué par l'alignement des trois axes 27, 28 et 31. La platine 24 est alors automatiquement entraînée en rotation par la traction qu'exerce sur elle l'élément de retenue arrière via la tringle 10 et la deuxième biellette 30. A la fin de la rotation, le dispositif se trouve dans la disposition représentée à la figure 9. Dans cette disposition, les trois axes 27, 28 et 31 sont alignés.When a trip command is supplied to the actuation box by the control box, the rotary actuating means of the triggering device constituted by the motor rotates the plate 24 sufficiently to exceed the unstable equilibrium point. consisting of the alignment of the three axes 27, 28 and 31. The plate 24 is then automatically rotated by the traction exerted on it the rear retaining element via the rod 10 and the second link 30. At the end of the rotation, the device is in the arrangement shown in figure 9 . In this arrangement, the three axes 27, 28 and 31 are aligned.

Grâce à un tel dispositif, la course de translation de l'élément de retenue arrière 3 est égale au double de la distance séparant l'axe principal du premier axe secondaire additionné du double de la distance séparant l'axe principal 28 du second axe secondaire 31.With such a device, the translation travel of the rear retaining element 3 is equal to twice the distance separating the main axis from the first secondary axis plus double the distance separating the main axis 28 from the second secondary axis 31.

Bien entendu, d'autres boîtiers d'actionnement 8 sont envisageables dans le cadre de l'invention.Of course, other actuating housings 8 are conceivable within the scope of the invention.

L'invention ne se limite pas aux quelques modes de réalisations décrits ci-dessus à titre d'exemple. On pourra par exemple envisager que le dispositif de déclenchement supplémentaire n'agira non plus en translatant l'élément de retenue arrière, mais en le faisant pivoter. Mais encore; en translatant, ou en faisant pivoter, l'élément de retenue avant. Enfin, il est également envisageable que le dispositif de déclenchement supplémentaire agisse sur l'élément de retenue avant et sur l'élément de retenue arrière.The invention is not limited to the few embodiments described above as an example. It may for example be envisaged that the additional triggering device will not act either by translating the rear retaining element, but by rotating it. But still; by translating, or rotating, the front retainer. Finally, it is also conceivable that the additional triggering device acts on the front retaining element and on the rear retaining element.
