Abstract

The boot fixing (1) has a body (2) which is connected through a mounting base (3) onto an alpine ski. The body has a boot-retaining jaw which is movable in a lateral direction in response to the boot against a return spring (15) housed in the body. A compensator (30) lowers the return force exerted by the spring on the jaw in response to a force exerted on a lever pivoted on the base. A support plate (41) takes the boot sole. The support plate can tip laterally around an axle in the vertical and horizontal plane. The plate is supported on either side the pivoting axle by movable connectors (47) whose front end rest simply supported on the compensator. The plate pivoting axle can move in a vertical direction with a limited amplitude. <IMAGE>

Description

L'invention concerne un élément de fixation de ski alpin, destiné à retenir une chaussure en appui sur un ski, et à la libérer en cas de sollicitation excessive.The invention relates to an alpine ski binding element, intended to retain a shoe resting on a ski, and to release it in the event of excessive stress.

Il est connu de retenir une chaussure en appui sur un ski au moyen d'un élément de fixation avant et un élément de fixation arrière. Ces éléments ont pour fonction première de retenir la chaussure sur le ski, de façon à permettre au skieur de guider son ski, notamment par des efforts qu'il transmet à sa chaussure en fonction de la trajectoire qu'il souhaite suivre et des réactions que le ski lui transmet. Une autre fonction de ces éléments de fixation est de relâcher cette retenue de la chaussure, c'est-à-dire de libérer la chaussure lorsque les efforts entre la chaussure et le ski deviennent excessifs au point de provoquer des lésions de la jambe du skieur. Mais il est difficile de discerner à partir de quel moment une sollicitation devient vraiment dangereuse pour la jambe du skieur. D'un autre côté, libérer la chaussure alors que ce n'est pas nécessaire constitue ce qu'on dénomme habituellement un déclenchement intempestif.It is known to retain a shoe resting on a ski by means of an element front fixing element and a rear fixing element. These elements have the function first to hold the boot on the ski, so that the skier can guide his ski, in particular by efforts that he transmits to his shoe in function of the trajectory that he wishes to follow and of the reactions that the ski transmits to him. A other function of these fasteners is to release this restraint from the shoe, that is to say to release the shoe when the forces between the shoe and ski become excessive to the point of causing injury to the skier's leg. But it is difficult to discern when a solicitation becomes really dangerous for the skier's leg. On another side, releasing the shoe when it is not necessary is what we usually called an untimely trigger.

Chaque élément de retenue présente habituellement une mâchoire portée par un corps qui est mobile contre la force de rappel exercée par un ressort d'énergie, généralement un ressort de compression.Each retainer usually has a jaw carried by a body which is movable against the restoring force exerted by an energy spring, usually a compression spring.

L'invention concerne plus particulièrement un élément de fixation avant. Habituellement, l'élément de fixation avant réagit à une sollicitation latérale de l'extrémité avant de la chaussure. Une telle sollicitation découle d'une sollicitation en torsion pure sur la jambe du skieur.The invention relates more particularly to a front fixing element. Usually the front fastener reacts to a lateral stress from the front end of the shoe. Such solicitation results from a solicitation in pure twist on the skier's leg.

Certains éléments de fixation présentent un mécanisme de compensation qui réagit en cas de sollicitation en torsion combinée à une chute vers l'avant du skieur. Un tel mécanisme est décrit par exemple dans la demande de brevet allemand publiée sous le numéro 29 05 837. Ce mécanisme comprend un plaque de support de la chaussure qui est mobile verticalement, dont le mouvement provoqué par une pression verticale vers le bas de la chaussure abaisse la force de rappel que le ressort exerce sur la mâchoire.Some fasteners have a compensation mechanism which reacts in the event of torsional stress combined with a forward fall of the skier. Such a mechanism is described for example in the patent application German published under number 29 05 837. This mechanism includes a plate shoe support which is vertically movable, the movement of which caused by vertical downward pressure of the shoe lowers the force reminder that the spring exerts on the jaw.

Un autre mécanisme est décrit dans la demande de brevet allemand publiée sous le numéro 33 35 878. Ce mécanisme comprend aussi une plaque de support de la chaussure qui est mobile verticalement et qui force la mâchoire à se déplacer dans le sens de la libération de la chaussure. De tels dispositifs compensent l'augmentation des frottements de la chaussure sur ses appuis que la composante vers l'avant de la chute induit. De tels mécanismes donnent satisfaction tant que la composante latérale de la chute reste prépondérante par rapport à la composante verticale.Another mechanism is described in the published German patent application under number 33 35 878. This mechanism also includes a support plate shoe that is vertically movable and forces the jaw to move in the direction of release of the shoe. Such devices compensate the increased friction of the shoe on its supports as the component forward of the induced fall. Such mechanisms are satisfactory as long as the lateral component of the fall remains preponderant compared to the component vertical.

Les éléments de fixation actuellement existants présentent par ailleurs un dispositif permettant d'adapter cet élément à des épaisseurs différentes de semelle de chaussure. Généralement, on adopte une plage de réglage de l'ordre de 2 mm qui correspond à la tolérance d'épaisseur d'une semelle de chaussure selon la norme DIN 7880.The existing fastening elements also have a device for adapting this element to different thicknesses of sole shoe. Generally, an adjustment range of the order of 2 mm is adopted which corresponds to the thickness tolerance of a shoe sole according to the DIN 7880 standard.

Certains éléments de fixation réalisent de façon automatique ce réglage hauteur. Parmi eux, on connaít par ailleurs d'après la demande de brevet européen publiée sous le numéro 580 996 un élément de fixation qui présente un mécanisme de compensation du type précédemment évoqué, dont la pédale de support est surélevée au repos par rapport au levier qui actionne le mécanisme de compensation. A l'engagement de la chaussure, la pédale de support s'abaisse jusqu'à ce qu'elle entre en contact avec le levier de compensation. Ceci réalise l'adaptation automatique de l'élément de fixation à l'épaisseur de la chaussure. A partir de cette position, la plaque d'appui peut exercer une action sur le mécanisme de compensation. Les deux phases de fonctionnement de la plaque d'appui s'enchaínent selon le même mouvement de rotation de la plaque autour d'un axe sensiblement transversal.Certain fastening elements perform this height adjustment automatically. Among them, we also know from the published European patent application under the number 580 996 a fixing element which has a mechanism for compensation of the type previously mentioned, of which the support pedal is raised at rest relative to the lever which actuates the compensation. When the shoe is engaged, the support pedal lowers until it comes into contact with the compensation lever. This achieves automatic adaptation of the fastening element to the thickness of the shoe. AT from this position, the support plate can exert an action on the mechanism compensation. The two operating phases of the backing plate follow the same movement of rotation of the plate around an axis substantially transverse.

Cet élément de fixation présente comme avantage que la pédale de support de la chaussure à la fois assure la fonction d'adaptation à l'épaisseur de la semelle, et à la fois commande le mécanisme de compensation.This fixing element has the advantage that the support pedal the shoe both performs the function of adapting to the thickness of the sole, and both controls the compensation mechanism.

Un des buts de l'invention est d'améliorer encore ce type d'élément de fixation en permettant une libération plus facile de la chaussure, en particulier dans certains types de chutes.One of the aims of the invention is to further improve this type of fastening element. allowing easier release of the shoe, especially in certain types of falls.

On a en effet remarqué que dans le cas de certaines chutes dites "avant torsion" c'est-à-dire avec une composante vers l'avant et une composante latérale, la composante latérale n'est pas suffisante pour provoquer le basculement latéral de la mâchoire. On assiste alors à un vrillage de la chaussure qui se coince entre la mâchoire et sa plaque de support. Les mécanismes de compensation actuellement connus ne sont pas suffisamment actifs pour faciliter l'ouverture de la mâchoire. Il arrive que ces chutes soient dangereuses, et causent des lésions en particulier au niveau des genoux du skieur.We have indeed noticed that in the case of certain falls called "before torsion" that is to say with a forward component and a lateral component, the lateral component is not sufficient to cause lateral tilting of jaw. There is then a twisting of the shoe which gets stuck between the jaw and its support plate. Compensation mechanisms currently known are not active enough to facilitate the opening of the jaw. he these falls can be dangerous, and cause injury in particular to level of the skier's knees.

Un autre but de l'invention est de proposer un élément de fixation dont la construction soit simple.Another object of the invention is to provide a fastening element whose construction be simple.

Selon l'invention, l'ément de retenue d'une chaussure sur une planche de glisse, notamment un ski alpin comprend un corps prévu pour être relié au ski par l'intermédiaire d'une embase. Le corps porte une mâchoire de retenue de la chaussure, la mâchoire étant mobile au moins en partie et au moins selon une direction latérale en réponse aux sollicitations de la chaussure, contre la force de rappel d'un ressort logé dans le corps. L'élément comprend un moyen de compensation pour abaisser la force de rappel que le ressort exerce sur la mâchoire en réponse à un effort exercé sur un levier articulé par rapport au corps ou à l'embase, et il présente par ailleurs une plaque d'appui prévue pour recevoir la semelle de chaussure,According to the invention, the retaining element of a shoe on a board gliding, in particular an alpine ski comprises a body intended to be connected to the ski by through a base. The body carries a retaining jaw of the shoe, the jaw being movable at least in part and at least according to a lateral direction in response to shoe stresses, against the force of reminder of a spring housed in the body. The element includes a means of compensation to lower the restoring force that the spring exerts on the jaw in response to a force exerted on a lever articulated relative to the body or at the base, and it also has a support plate designed to receive the shoe sole,

Il est caractérisé par le fait que la plaque d'appui est mobile en basculement latéral autour d'un axe de basculement orienté sensiblement dans un plan vertical et longitudinal, que la plaque d'appui est en appui de chaque côté de l'axe de basculement sur des moyens de liaison mobiles dont l'extrémité avant repose en appui simple sur le moyen de compensation, que l'axe de basculement de la plaque est mobile selon une direction verticale sur une amplitude limitée, qu'un moyen de rappel élastique rappelle de façon élastique la plaque en position élevée.It is characterized by the fact that the support plate is movable in tilting lateral about a tilt axis oriented substantially in a vertical plane and longitudinal, that the support plate is in support on each side of the axis of tilting on mobile connection means whose front end rests in simple support on the compensation means, that the tilt axis of the plate is movable in a vertical direction over a limited amplitude, that a elastic return means resiliently returns the plate in position high.

Le fait de rendre la plaque d'appui mobile autour d'un axe de basculement longitudinal permet d'actionner le mécanisme de compensation lors du vrillage de la chaussure. On pense que cela permet une libération plus facile de la chaussure, en particulier dans le cas d'une chute avant-torsion. En effet, le mécanisme de compensation diminue la force que la mâchoire oppose à l'ouverture, et de ce fait compense l'augmentation des frottements induits par le vrillage de la chaussure.The fact of making the support plate mobile around a tilting axis longitudinal allows the compensation mechanism to be actuated during the twisting of the shoe. It is believed to allow easier release of the shoe, especially in the case of a pre-twist fall. Indeed, the mechanism of compensation decreases the force that the jaw opposes to the opening, and thereby compensates for the increased friction induced by the twisting of the shoe.

Le fait de rendre l'axe de basculement de la plaque de support mobile selon une direction verticale permet d'assurer la fonction d'adaptation à l'épaisseur de la semelle de chaussure, alors que les mouvements de la plaque de support pour sa fonction de compensation et cette fonction d'adaptation sont de nature distincte.The fact of making the tilting axis of the support plate mobile according to a vertical direction ensures the adaptation function to the thickness of the shoe sole, while the movements of the support plate for its compensation function and this adaptation function are separate in nature.

Selon une autre caractéristique de l'invention, la plaque de support est rappelée en position surélevée par un ressort qui exerce son action sur les moyens de liaison reliant la plaque de support et le mécanisme de compensation. Ainsi, la plaque de support est maintenue en position horizontale, sans jeu, par les moyens de liaison, en particulier en l'absence de chaussure.According to another characteristic of the invention, the support plate is recalled in the raised position by a spring which exerts its action on the means of link connecting the support plate and the compensation mechanism. So the support plate is held in a horizontal position, without play, by the means of connection, in particular in the absence of shoe.

Les figures 9 et 10 sont relatives à une variante de réalisation.Figures 9 and 10 relate to an alternative embodiment.

L'élément de fixation avant 1 représenté dans les figures 1 à 3 est connu pour l'essentiel d'après la demande de brevet français publiée sous le numéro FR 2 640 516.The front fixing element 1 represented in FIGS. 1 to 3 is known for the essentials according to the French patent application published under the number FR 2,640,516.

Il comprend un corps 2 relié à une embase 3 qui est reliée solidairement au ski par tout moyen approprié et par exemple par des vis. Vue de dessus, l'embase présente une forme de "U" ouvert vers l'arrière, avec deux branches latérales 3a et 3b.It includes a body 2 connected to a base 3 which is integrally connected to the ski by any suitable means and for example by screws. Top view, the base has a "U" shape open towards the rear, with two lateral branches 3a and 3b.

Le corps est mobile verticalement par rapport à l'embase par une liaison déformable, localisée dans la zone 9 à la jonction entre le corps et l'embase. Le corps et l'embase sont reliés en continu par cette zone déformable et forment un élément monobloc.The body is movable vertically relative to the base by a link deformable, located in zone 9 at the junction between the body and the base. The body and the base are continuously connected by this deformable zone and form a monobloc element.

Le corps 2 porte une mâchoire 4 de retenue de l'extrémité avant de la chaussure. La mâchoire 4 comprend deux ailes de retenue latérale 5 et 6, respectivement articulées au corps 2 autour d'axes 7 et 8. La mâchoire 4 comprend aussi un serre-semelle 12 de retenue verticale de la chaussure.The body 2 carries a jaw 4 retaining the front end of the shoe. The jaw 4 comprises two lateral retaining wings 5 and 6, respectively articulated to the body 2 around axes 7 and 8. The jaw 4 comprises also a sole clamp 12 for vertical retention of the shoe.

Les ailes 5 et 6 sont mobiles en réponse aux sollicitations de la chaussure, contre la force de rappel que leur applique un ressort 15.The wings 5 and 6 are movable in response to the stresses of the shoe, against the return force applied to them by a spring 15.

Le ressort 15 est logé dans le corps. Il actionne un piston 16 également logé et guidé dans le corps pour un mouvement de translation longitudinal. Les figures montrent que le piston est logé et guidé dans un logement 17 du corps, et que le ressort est engagé à l'intérieur du piston. Son extrémité avant est en appui contre le fond du piston, situé du côté avant de l'élément de fixation. Une vis 20 dont la tête est retenue à l'avant du corps traverse par ailleurs le piston et le ressort, et présente vers l'arrière un écrou 21 qui retient l'extrémité arrière du ressort. Une rotation de la vis entraíne le ressort en translation, ce qui permet d'ajuster la compression initiale du ressort.The spring 15 is housed in the body. It actuates a piston 16 also housed and guided in the body for a longitudinal translational movement. The figures show that the piston is housed and guided in a housing 17 of the body, and that the spring is engaged inside the piston. Its front end is pressed against the bottom of the piston, located on the front side of the fixing element. A screw 20 whose head is retained at the front of the body, moreover passes through the piston and the spring, and has a nut 21 at the rear which retains the rear end of the spring. A rotation of the screw drives the spring in translation, which allows to adjust the initial compression of the spring.

Les ailes 5 et 6 présentent au-delà de leur axe d'articulation au corps 7 et 8 un petit bras 5a, 6a, qui entraíne vers l'arrière le piston 16 en prenant appui contre un épaulement 23 situé dans la partie arrière supérieure du piston 16.The wings 5 and 6 have beyond their axis of articulation to the body 7 and 8 a small arm 5a, 6a, which drives the piston 16 backwards by pressing against a shoulder 23 located in the upper rear part of the piston 16.

L'élément 1 présente en outre un mécanisme de compensation qui allège la force de rappel que le ressort 15 exerce sur les ailes 5 et 6.Element 1 also has a compensation mechanism which lightens the restoring force that the spring 15 exerts on the wings 5 and 6.

Ce mécanisme comprend un basculeur 30 qui est logé en partie entre les branches 3a et 3b de l'embase 3. Le basculeur est articulé autour d'un axe 32 porté par ces branches.This mechanism comprises a rocker 30 which is partly housed between the branches 3a and 3b of the base 3. The rocker is articulated around an axis 32 carried by these branches.

Le basculeur 30 présente un bras approximativement horizontal 33 qui est accessible sur l'arrière de l'élément de fixation entre les branches 3a et 3b de l'embase. Le bras 33 offre vers l'arrière un appui pour une pédale de commande. Cette pédale sera décrite plus en détail ultérieurement.The rocker 30 has an approximately horizontal arm 33 which is accessible on the rear of the fixing element between the branches 3a and 3b of the base. The arm 33 offers rearward support for a control pedal. This pedal will be described in more detail later.

Le basculeur 30 présente en outre un bras approximativement vertical formé par deux patins latéraux qui passent de chaque côté du piston 16, et qui portent chacun sur un épaulement 37 que le piston présente sous l'épaulement 23 des ailes. Seul le patin 35 est visible dans les figures.The rocker 30 also has an approximately vertical arm formed by two lateral pads which pass on each side of the piston 16, and which carry each on a shoulder 37 which the piston has under the shoulder 23 of wings. Only the pad 35 is visible in the figures.

Dans le mode de réalisation illustré dans les figures, le mécanisme de compensation présente en outre une tige de liaison 36 qui relie le basculeur 30 à la partie arrière du corps 2. L'articulation de la tige 36 au basculeur 30 est située en avant de l'axe 32. La tige transmet au basculeur 30, et donc au piston 16, les mouvements d'élévation du corps qui se produisent notamment lors d'une sollicitation verticale de la chaussure dans la mâchoire.In the embodiment illustrated in the figures, the compensation also has a connecting rod 36 which connects the rocker 30 to the rear part of the body 2. The articulation of the rod 36 to the rocker 30 is located at front of the axis 32. The rod transmits to the rocker 30, and therefore to the piston 16, the body elevation movements that occur especially during a vertical loading of the shoe in the jaw.

La construction de l'élément de fixation qui vient d'être décrite n'est naturellement pas limitative. D'autres constructions peuvent convenir, du moment où elles présentent ou où elles peuvent recevoir un mécanisme de compensation. De telles constructions sont par exemple décrites dans les demandes de brevet allemands publiées sous les numéros 38 40 949, 33 43 545. D'autres constructions peuvent aussi convenir.The construction of the fastener which has just been described is not naturally not limiting. Other constructions may be suitable, as long as where they present or where they can receive a compensation mechanism. Such constructions are for example described in patent applications publications published under the numbers 38 40 949, 33 43 545. Other constructions may also be suitable.

L'élément de fixation 1 comprend par ailleurs un dispositif d'appui 40 pour l'extrémité avant de la semelle de chaussure.The fixing element 1 also comprises a support device 40 for the front end of the shoe sole.

Le dispositif d'appui présente une plaque de support 41 sur laquelle la semelle de chaussure repose. La plaque 41 peut être équipée dans sa partie supérieure de tout revêtement approprié destiné à faciliter le glissement latéral de la chaussure, par exemple une plaquette de PTFE. Elle présente une largeur qui est de l'ordre de la largeur du ski à ce niveau. Dans le mode de représentation illustré, la plaque 41 est portée par un axe 42 orienté selon une direction longitudinale et approximativement horizontale. La plaque 41 peut basculer autour de cet axe d'un côté ou de l'autre.The support device has a support plate 41 on which the sole shoe rests. The plate 41 can be equipped in its upper part with any suitable coating intended to facilitate lateral sliding of the shoe, for example a PTFE plate. It has a width which is of the order of the width of the ski at this level. In the illustrated representation mode, the plate 41 is carried by an axis 42 oriented in a longitudinal direction and approximately horizontal. The plate 41 can tilt around this axis by a side or the other.

L'axe 41 est monté dans un palier formé par des plots 43, 44, solidaires d'un socle 39 qui est relié solidairement à l'embase 3. Le socle prolonge vers l'arrière l'embase 3. Toute autre disposition appropriée pourrait aussi convenir, et par exemple, le socle pourrait former un ensemble monobloc avec l'embase.The axis 41 is mounted in a bearing formed by studs 43, 44, integral with a base 39 which is integrally connected to the base 3. The base extends backwards base 3. Any other suitable arrangement could also be suitable, and therefore example, the base could form a one-piece assembly with the base.

Les plots 43 et 44 qui portent l'axe 41 permettent un mouvement de l'axe 42, pour une amplitude limitée, dans un plan longitudinal et vertical. Par exemple, ainsi que cela est représenté, le plot avant 43 présente pour l'axe 42 un orifice oblong 45 dont la grande dimension est dirigée verticalement. Le plot avant 44 retient l'autre extrémité de l'axe 42 sans mouvement vertical, mais il est prévu pour permettre le mouvement de l'axe 42 dans le trou oblong 45 du plot 43. The studs 43 and 44 which carry the axis 41 allow movement of the axis 42, for a limited amplitude, in a longitudinal and vertical plane. For example, as well as shown, the front stud 43 has an oblong hole for the axis 42 45 whose large dimension is directed vertically. The front stud 44 retains the other end of the axis 42 without vertical movement, but it is intended to allow the movement of the axis 42 in the oblong hole 45 of the stud 43.

Des moyens de liaison relient par ailleurs la plaque 41 au basculeur 30. Ces moyens transmettent le mouvement de basculement de la plaque autour de l'axe 41 sous la forme d'un effort vertical exercé vers le bas sur le bras 33 du basculeur 30.Connection means also connect the plate 41 to the rocker 30. These means transmit the tilting movement of the plate around the axis 41 in the form of a vertical force exerted downwards on the arm 33 of the rocker 30.

Dans le mode de réalisation représenté dans les figures, les moyens de liaison comprennent une tige 48 pliée selon une forme approximative de "U" dont les branches 46 et 47 passent sous la plaque 41, de part et d'autre de l'axe 42, et convergent vers le basculeur 30. Dans sa partie arrière, la tige 48 est maintenue dans un logement formé par une patte 49 solidaire du socle 45. Les branches de la tige peuvent osciller autour de la zone définie par ce logement. De préférence, la tige 48 présente une zone aplatie en son milieu. Cette zone facilite la mise en place et la circulation de l'axe 42.In the embodiment shown in the figures, the connecting means include a rod 48 bent in an approximate "U" shape, the branches 46 and 47 pass under the plate 41, on either side of the axis 42, and converge towards the rocker 30. In its rear part, the rod 48 is held in a housing formed by a lug 49 integral with the base 45. The branches of the rod can oscillate around the area defined by this housing. Preferably, the rod 48 has a flattened area in the middle. This area makes setting up easier place and the circulation of the axis 42.

Avantageusement, la tige 48 est réalisée en acier à ressort, ou en un matériau présentant une certaine élasticité. Ceci améliore la transmission au basculeur 30 du mouvement de basculement de la plaque 41.Advantageously, the rod 48 is made of spring steel, or of a material with a certain elasticity. This improves transmission to rocker 30 of the tilting movement of the plate 41.

La plaque 41 présente à sa face inférieure, de chaque côté de l'axe 42, une zone d'appui pour chacune des branches 46, 47. De préférence, cette zone d'appui est formée par un plot 51, 52, en saillie vers le bas. De cette façon, la zone de contact est localisée avec précision, même lors des mouvements de basculement de la plaque.The plate 41 has on its underside, on each side of the axis 42, a support zone for each of the branches 46, 47. Preferably, this zone support is formed by a stud 51, 52, projecting downward. In this way, the area contact is precisely located, even when moving tilting of the plate.

Vers l'avant, les branches 46 et 47 de la tige sont prévues pour venir reposer librement sur le bras 33 du basculeur 30, en arrière de l'axe 32, selon une direction verticale vers le bas.Forward, the branches 46 and 47 of the rod are provided to come to rest freely on the arm 33 of the rocker 30, behind the axis 32, in a direction vertical down.

Un ressort 54 rappelle par ailleurs vers le haut l'extrémité avant des branches 46 et 47. Dans le mode de réalisation illustré, le ressort 54 est un ressort de compression disposé entre le socle 45 et l'extrémité avant des branches 46 et 47.A spring 54 also recalls upwards the front end of the branches 46 and 47. In the illustrated embodiment, the spring 54 is a spring of compression disposed between the base 45 and the front end of the branches 46 and 47.

De préférence, le ressort 54 est relativement raide, et il est prévu pour relever l'extrémité avant des branches 46 et 47 largement au-dessus du bras 33 du basculeur.Preferably, the spring 54 is relatively stiff, and it is intended to raise the front end of the branches 46 and 47 largely above the arm 33 of the rocker.

En résumé, la plaque 41 est mobile autour de l'axe 42. La plaque et l'axe sont mobile verticalement selon une trajectoire et une amplitude définie principalement par l'orifice oblong 45. La plaque est par ailleurs en appui par des plots 51 et 52 sur les branches 46 et 47 qui assurent la liaison avec le basculeur 30 des moyens de compensation, et les branches sont mobiles vers le bas contre la force de rappel opposée par un ressort 54.In summary, the plate 41 is movable around the axis 42. The plate and the axis are vertically movable along a mainly defined trajectory and amplitude by the oblong opening 45. The plate is also supported by studs 51 and 52 on the branches 46 and 47 which provide the connection with the rocker 30 of the means compensation, and the branches are movable downwards against the restoring force opposed by a spring 54.

Le ressort 54 repousse vers le haut les branches 46 et 47. Ces branches, à leur tour, entraínent vers le haut la plaque 41 et son axe d'articulation 42. C'est l'orifice oblong 45 qui limite le mouvement vers le haut de la plaque et des branches. Les dimensions et la position de cet orifice sont prévues pour que, au repos, l'extrémité avant des branches s'élève au-dessus du basculeur à une distance correspondant sensiblement à la tolérance d'épaisseur que présentent les semelles de chaussure de ski, soit 2 millimètres. Toutefois, cette valeur n'est nullement limitative.The spring 54 pushes up the branches 46 and 47. These branches, at their turn, drive upward the plate 41 and its hinge pin 42. It is the orifice oblong 45 which limits the upward movement of the plate and the branches. The dimensions and position of this orifice are provided so that, at rest, the end front of the branches rises above the rocker at a corresponding distance substantially to the thickness tolerance of the shoe soles ski, or 2 millimeters. However, this value is in no way limiting.

Les dimensions et la position de l'orifice 45 sont en outre prévues pour que l'extrémité de l'axe 42 atteigne l'extrémité inférieure de l'orifice oblong 45 lorsque l'extrémité avant des branches 46 et 47 arrive au contact du bras 33 du basculeur.The dimensions and the position of the orifice 45 are also provided so that the end of the axis 42 reaches the lower end of the oblong orifice 45 when the front end of the branches 46 and 47 comes into contact with the arm 33 of the rocker.

Le fonctionnement du dispositif d'appui est le suivant. En l'absence de chaussure, le ressort 54 repousse vers le haut les branches 46 et 47, ainsi que la plaque 41 et l'axe 42. L'extrémité avant des branches est élevée bien au-dessus du bras horizontal 33 du basculeur. La plaque est sollicitée vers le haut par les branches, mais retenue par son axe 42 à l'intérieur du logement 45. De ce fait, elle se trouve maintenue sans jeu dans une assise horizontale. Cette position est illustrée en figure 6.The operation of the support device is as follows. In the absence of shoe, the spring 54 pushes up the branches 46 and 47, as well as the plate 41 and the axis 42. The front end of the branches is raised well above of the horizontal arm 33 of the rocker. The plate is biased upwards by the branches, but retained by its axis 42 inside the housing 45. Therefore, it is kept without play in a horizontal seat. This position is illustrated in figure 6.

Lorsque la chaussure est engagée, la plaque d'appui s'abaisse jusqu'à ce que l'extrémité avant des branches 46 et 47 arrive en appui sur le bras 33 du basculeur 30. Le ressort 54 oppose une résistance élastique à ce mouvement. Durant toute cette phase de mouvement, la plaque d'appui demeure sensiblement horizontale, et l'extrémité avant de la plaque décrit l'orifice oblong 45 selon une direction verticale. De préférence, l'axe 42 repose sur l'extrémité inférieure de l'orifice 45 au moment où les branches 46 et 47 arrivent en appui sur le basculeur 30. Cette phase de fonctionnement est illustré dans la figure 7.When the shoe is engaged, the support plate lowers until the front end of the branches 46 and 47 comes to bear on the arm 33 of the rocker 30. The spring 54 provides elastic resistance to this movement. During all this phase of movement, the support plate remains substantially horizontal, and the front end of the plate describes the oblong orifice 45 in a direction vertical. Preferably, the axis 42 rests on the lower end of the orifice 45 at when the branches 46 and 47 come to bear on the rocker 30. This operation phase is illustrated in figure 7.

A partir de la position représentée dans la figure 7, la plaque ne peut plus se déplacer vers le bas que par basculement autour de l'axe 42, en réponse aux sollicitations de basculement latéral que l'avant de la chaussure exerce sur la plaque. Le basculement de la plaque 41 autour de l'axe 42 provoque l'abaissement de l'une ou l'autre des branches 46 ou 47. La branche sollicitée transmet son effort au bras 33 du basculeur 30 qui pivote dans le sens d'une compensation, c'est-à-dire dans le sens correspondant à un recul du piston et une compression du ressort 15. Cette phase de fonctionnement est illustrée en figure 2.From the position shown in Figure 7, the plate can no longer move down only by tilting around axis 42, in response to lateral tilting stresses that the front of the shoe exerts on the plate. The tilting of the plate 41 around the axis 42 causes the lowering of one or other of the branches 46 or 47. The requested branch transmits its force to the arm 33 of the rocker 30 which pivots in the direction of a compensation, that is to say in the direction corresponding to a retraction of the piston and a compression of the spring 15. This operating phase is illustrated in FIG. 2.

Lorsque la sollicitation de basculement cesse, la plaque est ramenée en position horizontale par les branches 46 et 47, sous l'impulsion du basculeur 30 et du ressort 54.When the tilting stress ceases, the plate is returned to the position horizontal by the branches 46 and 47, under the impulse of the rocker 30 and the spring 54.

Lorsque la chaussure est dégagée de l'élément de fixation, le ressort 54 rappelle vers le haut la plaque et les branches 46 et 47, c'est-à-dire au dessus du bras 33 du basculeur 30. La plaque se retrouve maintenue sans jeu en position horizontale par les branches 46 et 47, étant donné qu'elle est par ailleurs retenue par son axe 42. On évite ainsi tout brimbalement qui pourrait se produire lors des manipulations de l'élément de fixation. Un tel brimbalement entraínerait une usure prématurée du dispositif d'appui. Il nuirait par ailleurs à la confiance qu'un utilisateur peu expert pourrait éprouver à priori envers un tel élément de fixation.When the shoe is released from the fastening element, the spring 54 point upwards the plate and the branches 46 and 47, that is to say above the arm 33 of rocker 30. The plate is found held without play in position horizontal by branches 46 and 47, since it is also retained by its axis 42. This avoids any brimbalement which could occur during handling of the fixing element. Such brimbalement would cause wear premature support device. It would also damage the confidence that a inexperienced user could experience a priori towards such a fastening element.

L'invention n'est pas limitée à la construction qui vient d'être décrite. Notamment, les moyens de liaison pourraient présenter une autre nature. La tige 48 mise en forme par pliage pourrait être remplacée par une plaque articulée dans sa partie arrière dans la zone de la patte 49 et ajourée dans sa partie centrale pour le passage de l'axe 42. La plaque d'appui 41 serait alors en appui contre cette plaque de chaque côté de l'axe 42.The invention is not limited to the construction which has just been described. Especially, the connection means could have another nature. The rod 48 shape by folding could be replaced by a hinged plate in its part rear in the area of the lug 49 and perforated in its central part for the passage of the axis 42. The support plate 41 would then be in abutment against this plate on each side of the axis 42.

En outre, le ressort 54 pourrait être remplacé par un autre moyen de rappel élastique, par exemple un ressort de torsion qui agirait sur les branches 46 et 47. Comme le montrent les figures 9 et 10, le ressort pourrait aussi être formé par une boucle centrale de la tige 48'. Au lieu d'une forme de "U", la tige 48' pourrait en effet présenter une forme de "W" dont la boucle centrale 60 formerait un angle avec les branches latérales. Cette boucle centrale serait en appui contre le socle 45, et l'énergie de rappel proviendrait alors de la torsion du fil. Comme dans le cas précédent, les extrémités des branches 46' et 47' seraient situées à l'aplomb du bras 33 du basculeur 30. Le cas échéant, le milieu de la boucle centrale 60 pourrait présenter une partie aplatie pour faciliter la circulation de l'axe 42.In addition, the spring 54 could be replaced by another return means elastic, for example a torsion spring which would act on the branches 46 and 47. As shown in Figures 9 and 10, the spring could also be formed by a central loop of the rod 48 '. Instead of a "U" shape, the rod 48 'could effect present a shape of "W" whose central loop 60 would form an angle with the lateral branches. This central loop would be in abutment against the base 45, and the return energy would then come from the twist of the wire. As in the case previous, the ends of the branches 46 'and 47' would be located directly above the arm 33 of rocker 30. If necessary, the middle of central loop 60 could present a flattened part to facilitate the circulation of the axis 42.

L'axe d'articulation 42 de la plaque 41 pourrait aussi être légèrement décalé en position ou en orientation, par rapport à la direction longitudinale médiane définie par le ski, de façon à créer une légère dissymétrie dans l'action des moyens de compensation. Dans ce cas, l'élément de fixation de l'autre pied présenterait un décalage symétrique.The articulation axis 42 of the plate 41 could also be slightly offset in position or orientation, relative to the defined median longitudinal direction by skiing, so as to create a slight asymmetry in the action of the means of compensation. In this case, the fixing element of the other leg would have a symmetrical shift.

L'invention n'est pas limitée au mode de réalisation décrit, elle en englobe les variantes, les équivalents, et d'une façon générale toutes les constructions définies dans les revendications annexées.The invention is not limited to the embodiment described, it encompasses the variants, equivalents, and generally all defined constructions in the appended claims.
