Definitions

  • the invention relates to a rear holding element of a binding of a boot on a ski, particularly suitable for ski touring. It also relates to a device for attaching a boot to a ski incorporating such a rear holding element. Finally, it also relates to a ski on which is fixed such a fixing device or such a rear holding member.
  • ski touring requires two different phases of operation of the ski.
  • a first climbing phase or more generally walking, the skier advances by raising his heel, which is not secured to the ski.
  • no ski braking device is used.
  • a second downhill phase the skier has his shoe fully secured to the ski, and practices skiing as in the case of downhill skiing. He thus needs a fixing device equipped with a trigger mechanism allowing him an automatic release of the shoe in case of fall, to avoid any injury and ensure its safety.
  • a braking device is then also essential to automatically brake the ski in case of triggering the attachment device, to prevent the ski from continuing to slide.
  • the ski touring braking device is generally equipped with a locking device, which makes it possible to block it and make it inactive in the first climbing phase. Downhill, the locking device is in an unlocked configuration, in which the brake operates in a manner similar to the brakes on alpine skis.
  • the present invention aims to provide a braking device for ski touring that is simple, user-friendly and reliable.
  • the heaving lever may comprise an actuating element, in particular at least one cam, of the locking device. It can act by a direct support on the locking device, including its locking member.
  • the bead gripper may include an abutment surface for holding the locking device in its unlocked position when the bale gripper is in its holding position.
  • the heaving lever can be a monoblock element.
  • the invention also relates to a fastening device for a ski, characterized in that it comprises a front holding member of a shoe and a rear holding member of a shoe as described above.
  • the invention also relates to a ski characterized in that it comprises such a ski binding device.
  • the longitudinal axis X as the horizontal axis extending from the back to the front of the ski, the front and rear being defined by the ordinary direction moving a skier in a straight line, the skier moving from the back to the front.
  • the transverse axis Y is defined as the horizontal axis perpendicular to the longitudinal axis X, the left and the right being defined according to the point of view of the skier.
  • the vertical axis Z is perpendicular to the horizontal plane defined by the X and Y axes, pointing upwards. We assume that the ski rests on a horizontal ground.
  • the figure 1 schematically illustrates an embodiment of a ski 1 provided with a fixing device 2 according to the invention.
  • the fixing device comprises a front holding element 3 and a rear holding element 4.
  • the front holding element 3 is able to cooperate with the front of a ski boot 6 and the rear holding element is suitable at cooperate with the back of the ski boot.
  • the ski is intended for the practice of ski touring. Ski touring mainly involves two phases of use.
  • a first phase called the climbing phase
  • the skier walks with the ski, usually on a slope that he goes up.
  • the skier's boot is fixed to the ski only via the front holding element 3.
  • the front holding element comprises a pivot connection of axis Y1, parallel to the transverse axis Y which allows the skier to lift the heel and thus facilitates its progression according to a natural movement of walking.
  • the heel of the shoe follows a circular path T1 around the axis Y1 of the pivot connection of the front holding element.
  • a second phase called downhill phase the skier practices skiing in the manner of alpine skiing and descends a sloping terrain.
  • the back of the shoe including a heel 6a of the shoe, for example by a sidewalk 6b arranged in the heel 6a, is fixed to the ski through the rear holding element.
  • the pivot connection of the front holding element is blocked and the boot is secured to the ski.
  • the skier may be required to manipulate the ski to prepare for the next phase.
  • the skier may stick or take off anti-kickback fluff on the sole of the ski.
  • the ski and / or the attachment device could be used for any other sport of gliding, for example for telemark, or even downhill skiing or cross-country skiing.
  • the rear holding element 4 in particular at least partially visible on the figure 8 , comprises a bead grip 7, a braking device 8, a locking device 9 of the braking device 8, and a lever 10. These elements are mounted on a base 11.
  • This base 11 has two vertical fins 30a, 30b positioned on the lateral sides of the base 11 on which is mounted the axis of rotation 31 of the lever 10 and the gripping heel 7.
  • the rear holding element 4 also comprises a plate 12 comprising guiding rails for adjusting the longitudinal position 12 of the base 11, in a known manner, visible on the figure 9 .
  • This device for adjusting the longitudinal position of the base 11 makes it possible to adjust the position of the base on a ski to adapt to the size of the shoe.
  • the rear holding element 4 also comprises a heel rest 14 on which the lower face of the heel of a shoe rests, and which also makes it possible to hold the boot sideways during the descent phase, thanks in particular to two flanges. 14a, 14b on both sides of the shoe.
  • the rear holding element 4 is symmetrical about a median plane of longitudinal and vertical symmetry XZ.
  • the gripping heel 7 is rotatable between a heel holding position 6a of a shoe, visible on the Figures 5 and 6 , in the descent configuration, and an open position for which the heel grip exerts no heel support, for example visible on the figure 4 , in boot configuration.
  • the heel grip comprises a jaw or an edge 7a extending substantially horizontally forwardly. When the heel grip is in the holding position, the edge 7a comes to cover the upper surface of a sidewalk 6b to hold the shoe.
  • the force produced by the heel gripping to maintain the heel of the boot can be adjusted by means of a trigger adjustment device 13.
  • An embodiment of such a trigger adjustment device may comprise a spring 13a and an adjusting screw 13b of the hardness of the spring.
  • the bead gripper is movable in a rotational movement relative to the base 11 along an axis parallel to the transverse axis Y between the holding position and the open position. In the open position, the heel gripper is tilted backwards by a simple rotation so that the edge 7a is positioned outside the path T1 of the sidewalk 6b of a shoe during the practice of walking, shown on the figure 1 .
  • a shoe 6 can pivot about the axis Y1 of the pivot connection of the holding element before without hitting the gripping heel 7.
  • the gripper heel is not animated of a complementary rearward translation movement in climb configuration, but can in any case take only the two positions mentioned above, that is to say the open and holding positions, by a single rotation movement.
  • This solution has the advantage of allowing the rear holding element to have a simple architecture, while allowing to achieve a configuration favorable to the rising phase. More specifically, the open position allows both the boot of the heel but also the lifting of the heel of the shoe for the climb, because of the mounting on the heel grip 7 of a foot pedal 35 retractable, as explained by the following.
  • the braking device 8 is movable between an active braking position, for which the braking device brakes the ski, and an inactive non-braking position, for which the braking device does not brake the ski.
  • the braking device visible in the active position on the Figures 10 and 11 , includes a conventional brake used on an alpine ski, as for example described in the document FR2788991 .
  • the brake comprises a pedal 15 intended to receive the support of the ski boot, in general a rear part of the sole of the boot, to allow it to change from the active position to the inactive position, position represented in particular Figures 8 and 9 .
  • the brake comprises a continuous metal element 16 comprising two braking limbs 16a, 16b, for a disposition on either side of the ski.
  • the brake may be non-continuous, be in several distinct parts, including two separate lateral branches.
  • the braking limbs In the active position of the braking device, the braking limbs extend downward under the lower surface of the ski to come rub on the snow and brake the ski.
  • the braking branches In the inactive position of the braking device, the braking branches extend parallel to the ski, above the lower surface of the ski so as to avoid any contact with the snow.
  • the branches of the braking device are thus substantially driven by a rotational movement.
  • the braking device occupies a fixed position longitudinally relative to the base 11.
  • the metal element 16 is symmetrical with respect to the plane of symmetry XZ and is rotatable relative to the base 11 along an axis Y2, shown in FIG. figure 10 , parallel to the transverse axis Y.
  • the metal element comprises on each branch a transverse zone 16c adapted to cooperate with the base.
  • the metal element also comprises a second transversal zone 16d crossing the pedal 15.
  • the pedal is fixed to the metal element by a pivot connection along an axis parallel to the transverse axis Y.
  • the pedal can be driven by a rotational movement around the Y2 axis while remaining substantially horizontal.
  • a high position of the pedal corresponds to an active position of the braking device, in which its branches 16a, 16b extend downwards.
  • a low position of the pedal corresponds to an inactive position of the braking device, in which its branches 16a, 16b are raised to avoid contact with the ground.
  • the metal element 16 has a natural elastic property which tends, in the absence of biasing the pedal, to position the braking device in its active position.
  • the brake may include any return spring tending to return it to the active braking position.
  • the locking device 9 is movable between a locking position, for example visible on the figures 2 and 7 , for which the locking device is adapted to hold the braking device in its inactive position, and an unlocking position, for example visible on the figures 4 and 5 , for which the locking device does not keep the braking device in its inactive position.
  • the pedal 15 comprises a hook 17, visible in particular on the Figures 2, 3 and 10 , made in the body of the pedal and the locking device 9 comprises a corresponding locking member, in the form of a hook 18, in particular visible on the Figures 2 and 3 movable in sliding connection along the longitudinal axis X.
  • the two hooks 17, 18 are able to cooperate to maintain the braking device in its inactive position.
  • an inactive locked position of the brake is obtained.
  • the hook 18 is in a rear position in which it is adapted to cooperate with the hook 17 of the pedal.
  • the locking device 9 is in the unlocking position, its hook 18 is in an advanced position, in which it can no longer cooperate with the hook 17 of the pedal.
  • the locking device 9 further comprises a return spring 19 exerting a return force on the hook 18, tending to return it to its rear locking position.
  • the active or inactive position of the braking device is then controlled only by a vertical support on the pedal 15, the braking device is unlocked. If the shoe bears on the pedal, the branches 16a, 16b of the brake pivot upwards and the braking device is inactive. If the shoe does not exert support on the pedal, the pedal goes up thanks to its elastic property, the branches 16a, 16b of the brake being then lowered in the braking position, and the braking device is active.
  • the hook 18 of the locking device 9 When the hook 18 of the locking device 9 is in its rear position, it is in the path of the hook 17 of the pedal 15. As long as the braking device is active, the two hooks 17, 18 are not engaged. As soon as the braking device is in the inactive position, for example following the support of a shoe on the pedal 15, the hook 18 can hook the hook 17 of the pedal 15. When the two hooks 17, 18 cooperate, that is, they are engaged with each other, the pedal 15 is held in its down position, and the braking device 8 is therefore kept inactive.
  • the two hooks each comprise a chamfer arranged so that the bearing of their respective chamfers causes an elastic movement of the hook 18 of the locking device 9 forward to allow the passage of the hook 17 of the pedal under this hook 18.
  • the hook 17 of the pedal is passed under the hook 18, the latter takes up its position towards the rear thanks to the effect of the return spring 19.
  • the locking device 9 could be arranged differently.
  • the longitudinal position of the two hooks 17, 18 could be reversed.
  • the return spring 19 could be supported by the pedal.
  • the connection between the hook 18 and an actuating member 20, which will be specified later, may have different shapes.
  • Lever 10, shown in figure 14 is movable relative to the gripping bead 7 between at least one mounting position and a stopping position.
  • the lever is adapted during its movement from the climbing position to the stopping position, to move the locking device 9 from its locking position to its unlocking position.
  • the locking device 9 comprises an actuating member 20, particularly visible on the figures 2 , 4 and 10 , integral with the hook 18, and able to interact with the lever 10.
  • the actuating member 20 is also movable in sliding connection along the longitudinal axis X relative to the base.
  • the actuating member may be housed in a recess formed in the base whose shape allows the sliding of the actuating member along the longitudinal axis X.
  • the lever 10 is movable relative to the Heel catch 7 and relative to the base 11 according to a pivot connection of axis Y3.
  • the lever may be a monoblock element, preferably made from injected plastic.
  • the lever can be formed from two pieces or more advantageously of parts fixed rigidly between them.
  • the lever 10 surrounds the gripping heel left and right, by two sides 21a, 21b, visible on the figure 12 , oriented substantially parallel to the longitudinal axis X and to the vertical axis Z.
  • These two blanks 21a, 21b are themselves surrounded by the vertical fins 30a, 30b of the base 11.
  • These two flanks are connected at their upper end by a bridge 22 adapted to pass over the gripping heel 7.
  • the bridge 22 may have an ergonomic shape adapted to manual actuation or actuation by through a ski pole.
  • the bridge 22 comprises a cavity 22a adapted to receive the support of the tip of a stick to push on the lever.
  • the bridge 22 also comprises a semi-circular aperture 22b at its rear end adapted to receive the handle of a stick to push the lever, a washer of the stick then passing under the lever.
  • the two sides 21a, 21b each comprise an opening 23 supporting the axis Y3 of rotation and an actuating cam 24.
  • the axis Y3 is located in a lower part of the lever 10 and the two cams 24 are located below the Y3 axis of rotation of the lever, at the lower ends of each flank 21a, 21b.
  • the rear holding element In the intermediate up position of the lever 10, the rear holding element being in a climb configuration, represented on the Figures 2 and 3 the two cams 24 do not press on the actuating member 20.
  • the position of the actuating member 20 (and the hook 18 which is secured thereto) is therefore only imposed by the effect of the return spring 19.

Description

L'invention concerne un élément de maintien arrière d'une fixation d'une chaussure sur un ski, particulièrement adapté au ski de randonnée. Elle concerne aussi un dispositif de fixation d'une chaussure sur un ski intégrant un tel élément de maintien arrière. Enfin, elle concerne aussi un ski sur lequel est fixé un tel dispositif de fixation ou un tel élément de maintien arrière.The invention relates to a rear holding element of a binding of a boot on a ski, particularly suitable for ski touring. It also relates to a device for attaching a boot to a ski incorporating such a rear holding element. Finally, it also relates to a ski on which is fixed such a fixing device or such a rear holding member.

La pratique du ski de randonnée nécessite deux phases différentes de fonctionnement du ski. Dans une première phase de montée, ou plus généralement de marche, le skieur avance en soulevant son talon, qui n'est pas solidarisé sur le ski. Dans cette première phase, aucun dispositif de freinage du ski n'est utilisé. Dans une seconde phase de descente, le skieur a sa chaussure totalement solidarisée sur le ski, et pratique le ski comme dans le cas du ski alpin. Il a ainsi besoin d'un dispositif de fixation équipé d'un mécanisme de déclenchement lui permettant une libération automatique de la chaussure en cas de chute, pour éviter toute blessure et assurer sa sécurité. Un dispositif de freinage est alors aussi indispensable pour freiner automatiquement le ski en cas de déclenchement du dispositif de fixation, pour empêcher le ski de continuer sa glisse.The practice of ski touring requires two different phases of operation of the ski. In a first climbing phase, or more generally walking, the skier advances by raising his heel, which is not secured to the ski. In this first phase, no ski braking device is used. In a second downhill phase, the skier has his shoe fully secured to the ski, and practices skiing as in the case of downhill skiing. He thus needs a fixing device equipped with a trigger mechanism allowing him an automatic release of the shoe in case of fall, to avoid any injury and ensure its safety. A braking device is then also essential to automatically brake the ski in case of triggering the attachment device, to prevent the ski from continuing to slide.

Pour répondre aux contraintes précédentes, le dispositif de freinage du ski de randonnée est en général équipé d'un dispositif de blocage, qui permet de le bloquer et le rendre inactif dans la première phase de montée. En descente, le dispositif de blocage se trouve dans une configuration débloquée, dans laquelle le frein fonctionne de manière similaire aux freins équipant les skis alpins.To meet the above constraints, the ski touring braking device is generally equipped with a locking device, which makes it possible to block it and make it inactive in the first climbing phase. Downhill, the locking device is in an unlocked configuration, in which the brake operates in a manner similar to the brakes on alpine skis.

Toutefois, les solutions existantes restent insatisfaisantes et la présente invention a pour objet de proposer un dispositif de freinage pour ski de randonnée qui soit simple, convivial à utiliser et fiable.However, the existing solutions remain unsatisfactory and the present invention aims to provide a braking device for ski touring that is simple, user-friendly and reliable.

A cet effet, l'invention repose sur un élément de maintien arrière d'une fixation d'une chaussure sur un ski, caractérisé en ce qu'il comprend :

  • un agrippe talon, mobile entre une position de maintien d'un talon d'une chaussure et une position ouverte dans laquelle l'agrippe talon n'exerce aucun maintien d'un talon d'une chaussure, et
  • un dispositif de freinage d'un ski, mobile entre une position active, dans laquelle le dispositif de freinage est apte à freiner un ski, et une position inactive, dans laquelle le dispositif de freinage n'est pas apte à freiner un ski, et
  • un dispositif de verrouillage du dispositif de freinage, mobile entre une position de verrouillage, dans laquelle le dispositif de verrouillage maintient le dispositif de freinage dans sa position inactive, et une position de déverrouillage, dans laquelle le dispositif de verrouillage ne maintient pas le dispositif de freinage dans sa position inactive, et
  • un levier de déchaussage, mobile par rapport à l'agrippe talon entre au moins une position de montée et une position de chaussage, le levier de déchaussage agissant sur le dispositif de verrouillage au cours de son déplacement de la position de montée à la position de chaussage de sorte à le déplacer de sa position de verrouillage à sa position de déverrouillage et/ou inversement.
For this purpose, the invention is based on a rear holding element of a binding of a boot on a ski, characterized in that it comprises:
  • a heel grip, movable between a heel holding position of a shoe and an open position in which the heel grip does not maintain a heel of a shoe, and
  • a ski braking device, movable between an active position, in which the braking device is able to brake a ski, and an inactive position, in which the braking device is not able to brake a ski, and
  • a locking device of the braking device, movable between a locking position, in which the locking device holds the braking device in its inactive position, and an unlocking position, in which the locking device does not hold the locking device; braking in its inactive position, and
  • a release lever movable with respect to the heel gripper between at least one climbing position and a running position, the release lever acting on the locking device during its movement from the climbing position to the driving position; boot so as to move it from its locking position to its unlocking position and / or vice versa.

Le levier de déchaussage peut comprendre un élément d'actionnement, notamment au moins une came, du dispositif de verrouillage. Il peut agir par un appui direct sur le dispositif de verrouillage, notamment son organe de verrouillage.The heaving lever may comprise an actuating element, in particular at least one cam, of the locking device. It can act by a direct support on the locking device, including its locking member.

L'agrippe talon peut comprendre une surface de butée pour maintenir le dispositif de verrouillage dans sa position de déverrouillage lorsque le l'agrippe talon est dans sa position de maintien.The bead gripper may include an abutment surface for holding the locking device in its unlocked position when the bale gripper is in its holding position.

Le levier de déchaussage peut être un élément monobloc.The heaving lever can be a monoblock element.

L'invention porte aussi sur un dispositif de fixation pour un ski, caractérisé en ce qu'il comprend un élément de maintien avant d'une chaussure et un élément de maintien arrière d'une chaussure tel que décrit précédemment.The invention also relates to a fastening device for a ski, characterized in that it comprises a front holding member of a shoe and a rear holding member of a shoe as described above.

L'invention porte aussi sur un ski caractérisé en ce qu'il comprend un tel dispositif de fixation de ski.The invention also relates to a ski characterized in that it comprises such a ski binding device.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

Pour faciliter la compréhension de la suite de la description, nous définissons l'axe longitudinal X comme l'axe horizontal s'étendant de l'arrière vers l'avant du ski, l'avant et l'arrière étant définis par la direction ordinaire de déplacement d'un skieur en ligne droite, le skieur se dirigeant de l'arrière vers l'avant. L'axe transversal Y est défini comme l'axe horizontal perpendiculaire à l'axe longitudinal X, la gauche et la droite étant définis selon le point de vue du skieur. L'axe vertical Z est perpendiculaire au plan horizontal défini par les axes X et Y, orienté vers le haut. Nous supposons que le ski repose sur un sol horizontal.To facilitate the understanding of the rest of the description, we define the longitudinal axis X as the horizontal axis extending from the back to the front of the ski, the front and rear being defined by the ordinary direction moving a skier in a straight line, the skier moving from the back to the front. The transverse axis Y is defined as the horizontal axis perpendicular to the longitudinal axis X, the left and the right being defined according to the point of view of the skier. The vertical axis Z is perpendicular to the horizontal plane defined by the X and Y axes, pointing upwards. We assume that the ski rests on a horizontal ground.

La figure 1 illustre schématiquement un mode de réalisation d'un ski 1 muni d'un dispositif de fixation 2 selon l'invention. Le dispositif de fixation comprend un élément de maintien avant 3 et un élément de maintien arrière 4. L'élément de maintien avant 3 est apte à coopérer avec l'avant d'une chaussure 6 de ski et l'élément de maintien arrière est apte à coopérer avec l'arrière de la chaussure de ski. Le ski est destiné à la pratique du ski de randonnée. Le ski de randonnée comprend principalement deux phases d'utilisation.The figure 1 schematically illustrates an embodiment of a ski 1 provided with a fixing device 2 according to the invention. The fixing device comprises a front holding element 3 and a rear holding element 4. The front holding element 3 is able to cooperate with the front of a ski boot 6 and the rear holding element is suitable at cooperate with the back of the ski boot. The ski is intended for the practice of ski touring. Ski touring mainly involves two phases of use.

Lors d'une première phase, dite phase de montée, le skieur marche avec le ski, généralement sur un terrain en pente qu'il remonte. Lors de la phase de montée, la chaussure du skieur est fixée au ski uniquement par l'intermédiaire de l'élément de maintien avant 3. L'élément de maintien avant comprend une liaison pivot d'axe Y1, parallèle à l'axe transversal Y ce qui permet au skieur de lever le talon et facilite ainsi sa progression selon un mouvement naturel de marche. Le talon de la chaussure suit une trajectoire T1 circulaire autour de l'axe Y1 de la liaison pivot de l'élément de maintien avant.During a first phase, called the climbing phase, the skier walks with the ski, usually on a slope that he goes up. During the climbing phase, the skier's boot is fixed to the ski only via the front holding element 3. The front holding element comprises a pivot connection of axis Y1, parallel to the transverse axis Y which allows the skier to lift the heel and thus facilitates its progression according to a natural movement of walking. The heel of the shoe follows a circular path T1 around the axis Y1 of the pivot connection of the front holding element.

Lors d'une deuxième phase dite phase de descente, le skieur pratique le ski à la manière du ski alpin et descend un terrain en pente. Lors de la phase de descente, l'arrière de la chaussure, notamment un talon 6a de la chaussure, par exemple par un trottoir 6b agencé dans le talon 6a, est fixé au ski par l'intermédiaire de l'élément de maintien arrière. La liaison pivot de l'élément de maintien avant est donc bloquée et la chaussure est solidarisée au ski. Entre la phase de montée et la phase de descente, le skieur peut être amené à manipuler le ski pour le préparer à la phase suivante. Par exemple, le skieur peut coller ou décoller des peluches anti-recul sur la semelle du ski. En variante, le ski et/ou le dispositif de fixation pourrait être utilisés pour tout autre sport de glisse, par exemple pour le télémark, voire le ski alpin ou le ski de fond.During a second phase called downhill phase, the skier practices skiing in the manner of alpine skiing and descends a sloping terrain. During the descent phase, the back of the shoe, including a heel 6a of the shoe, for example by a sidewalk 6b arranged in the heel 6a, is fixed to the ski through the rear holding element. The pivot connection of the front holding element is blocked and the boot is secured to the ski. Between the ascent phase and the descent phase, the skier may be required to manipulate the ski to prepare for the next phase. For example, the skier may stick or take off anti-kickback fluff on the sole of the ski. Alternatively, the ski and / or the attachment device could be used for any other sport of gliding, for example for telemark, or even downhill skiing or cross-country skiing.

L'élément de maintien arrière 4, notamment au moins partiellement visible sur la figure 8, comprend un agrippe talon 7, un dispositif de freinage 8, un dispositif de verrouillage 9 du dispositif de freinage 8, et un levier 10. Ces éléments sont montés sur une embase 11. Cette embase 11 présente deux ailettes verticales 30a, 30b positionnées sur les côtés latéraux de l'embase 11 sur lesquelles est monté l'axe de rotation 31 du levier 10 et de l'agrippe talon 7. En complément, l'élément de maintien arrière 4 comprend également une plaque 12 comprenant des glissières de guidage pour le réglage de la position longitudinale 12 de l'embase 11, de manière connue, visible sur la figure 9. Ce dispositif de réglage de la position longitudinale de l'embase 11 permet d'ajuster la position de l'embase sur un ski pour s'adapter à la taille de la chaussure. L'élément de maintien arrière 4 comprend aussi un repose talon 14 sur lequel s'appuie la face inférieure du talon d'une chaussure, et qui permet de réaliser également un maintien latéral de la chaussure en phase de descente, grâce notamment à deux rebords 14a, 14b de part et d'autre de la chaussure. Selon le mode de réalisation présenté, l'élément de maintien arrière 4 est symétrique selon un plan médian de symétrie XZ longitudinal et vertical.The rear holding element 4, in particular at least partially visible on the figure 8 , comprises a bead grip 7, a braking device 8, a locking device 9 of the braking device 8, and a lever 10. These elements are mounted on a base 11. This base 11 has two vertical fins 30a, 30b positioned on the lateral sides of the base 11 on which is mounted the axis of rotation 31 of the lever 10 and the gripping heel 7. In In addition, the rear holding element 4 also comprises a plate 12 comprising guiding rails for adjusting the longitudinal position 12 of the base 11, in a known manner, visible on the figure 9 . This device for adjusting the longitudinal position of the base 11 makes it possible to adjust the position of the base on a ski to adapt to the size of the shoe. The rear holding element 4 also comprises a heel rest 14 on which the lower face of the heel of a shoe rests, and which also makes it possible to hold the boot sideways during the descent phase, thanks in particular to two flanges. 14a, 14b on both sides of the shoe. According to the embodiment shown, the rear holding element 4 is symmetrical about a median plane of longitudinal and vertical symmetry XZ.

L'agrippe talon 7 est mobile en rotation entre une position de maintien du talon 6a d'une chaussure, visible sur les figures 5 et 6, en configuration de descente, et une position ouverte pour laquelle l'agrippe talon n'exerce aucun maintien du talon, par exemple visible sur la figure 4, en configuration de chaussage. A cet effet l'agrippe talon comprend une mâchoire ou un bord 7a s'étendant sensiblement horizontalement vers l'avant. Lorsque l'agrippe talon est dans la position de maintien, le bord 7a vient recouvrir la surface supérieure d'un trottoir 6b pour maintenir la chaussure. L'effort produit par l'agrippe talon pour maintenir le talon de la chaussure peut être ajusté au moyen d'un dispositif de réglage de déclenchement 13. Un mode de réalisation d'un tel dispositif de réglage de déclenchement, notamment visible sur les figures 3, 6 et 12, peut comprendre un ressort 13a et une vis de réglage 13b de la dureté du ressort. L'agrippe talon est mobile selon un mouvement de rotation relativement à l'embase 11 selon un axe parallèle à l'axe transversal Y entre la position de maintien et la position ouverte. En position ouverte, l'agrippe talon est donc basculé vers l'arrière par une simple rotation de manière à ce que le bord 7a soit positionné hors de la trajectoire T1 du trottoir 6b d'une chaussure lors de la pratique de la marche, représentée sur la figure 1. Ainsi, une chaussure 6 peut pivoter autour de l'axe Y1 de la liaison pivot de l'élément de maintien avant sans heurter l'agrippe talon 7. En remarque, dans ce mode de réalisation, l'agrippe talon n'est pas animé d'un mouvement complémentaire de translation vers l'arrière en configuration de montée, mais ne peut prendre dans tous les cas que les deux positions mentionnées ci-dessus, c'est-à-dire les positions ouverte et de maintien, par un seul mouvement de rotation. Cette solution présente l'avantage de permettre à l'élément de maintien arrière d'avoir une architecture simple, tout en permettant d'atteindre une configuration favorable à la phase de montée. Plus précisément, la position ouverte permet à la fois le chaussage de la talonnière mais également le soulèvement du talon de la chaussure pour la montée, du fait du montage sur l'agrippe talon 7 d'une pédale de chaussage 35 escamotable, comme explicité par la suite.The gripping heel 7 is rotatable between a heel holding position 6a of a shoe, visible on the Figures 5 and 6 , in the descent configuration, and an open position for which the heel grip exerts no heel support, for example visible on the figure 4 , in boot configuration. For this purpose the heel grip comprises a jaw or an edge 7a extending substantially horizontally forwardly. When the heel grip is in the holding position, the edge 7a comes to cover the upper surface of a sidewalk 6b to hold the shoe. The force produced by the heel gripping to maintain the heel of the boot can be adjusted by means of a trigger adjustment device 13. An embodiment of such a trigger adjustment device, in particular visible on the figures 3 , 6 and 12 , may comprise a spring 13a and an adjusting screw 13b of the hardness of the spring. The bead gripper is movable in a rotational movement relative to the base 11 along an axis parallel to the transverse axis Y between the holding position and the open position. In the open position, the heel gripper is tilted backwards by a simple rotation so that the edge 7a is positioned outside the path T1 of the sidewalk 6b of a shoe during the practice of walking, shown on the figure 1 . Thus, a shoe 6 can pivot about the axis Y1 of the pivot connection of the holding element before without hitting the gripping heel 7. Note, in this embodiment, the gripper heel is not animated of a complementary rearward translation movement in climb configuration, but can in any case take only the two positions mentioned above, that is to say the open and holding positions, by a single rotation movement. This solution has the advantage of allowing the rear holding element to have a simple architecture, while allowing to achieve a configuration favorable to the rising phase. More specifically, the open position allows both the boot of the heel but also the lifting of the heel of the shoe for the climb, because of the mounting on the heel grip 7 of a foot pedal 35 retractable, as explained by the following.

Le dispositif de freinage 8 est mobile entre une position active de freinage, pour laquelle le dispositif de freinage freine le ski, et une position inactive de non freinage, pour laquelle le dispositif de freinage ne freine pas le ski. Le dispositif de freinage, visible en position active sur les figures 10 et 11, comprend un frein conventionnel utilisé sur un ski alpin, tel que par exemple décrit dans le document FR2788991 . Le frein comprend une pédale 15 destinée à recevoir l'appui de la chaussure de ski, en général une partie arrière de la semelle de la chaussure, pour permettre son basculement de la position active à la position inactive, position notamment représentée sur les figures 8 et 9. Ensuite, le frein comprend un élément métallique 16 continu comprenant deux branches 16a, 16b de freinage, destinées à une disposition de part et d'autre du ski. En variante, le frein peut être non continu, se présenter en plusieurs parties distinctes, comprenant notamment deux branches latérales distinctes. Dans la position active du dispositif de freinage, les branches de freinage s'étendent vers le bas sous la surface inférieure du ski pour venir frotter sur la neige et freiner le ski. Dans la position inactive du dispositif de freinage, les branches de freinage s'étendent parallèlement au ski, au dessus de la surface inférieure du ski de manière à éviter tout contact avec la neige. Les branches du dispositif de freinage sont ainsi sensiblement animées d'un mouvement de rotation. Le dispositif de freinage occupe une position fixe longitudinalement relativement à l'embase 11.The braking device 8 is movable between an active braking position, for which the braking device brakes the ski, and an inactive non-braking position, for which the braking device does not brake the ski. The braking device, visible in the active position on the Figures 10 and 11 , includes a conventional brake used on an alpine ski, as for example described in the document FR2788991 . The brake comprises a pedal 15 intended to receive the support of the ski boot, in general a rear part of the sole of the boot, to allow it to change from the active position to the inactive position, position represented in particular Figures 8 and 9 . Then, the brake comprises a continuous metal element 16 comprising two braking limbs 16a, 16b, for a disposition on either side of the ski. Alternatively, the brake may be non-continuous, be in several distinct parts, including two separate lateral branches. In the active position of the braking device, the braking limbs extend downward under the lower surface of the ski to come rub on the snow and brake the ski. In the inactive position of the braking device, the braking branches extend parallel to the ski, above the lower surface of the ski so as to avoid any contact with the snow. The branches of the braking device are thus substantially driven by a rotational movement. The braking device occupies a fixed position longitudinally relative to the base 11.

L'élément métallique 16 est symétrique par rapport au plan de symétrie XZ et est mobile en rotation par rapport à l'embase 11 suivant un axe Y2, représenté sur la figure 10, parallèle à l'axe transversal Y. Pour supporter cette liaison en rotation, l'élément métallique comprend sur chaque branche une zone transversale 16c apte à coopérer avec l'embase. L'élément métallique comprend également une deuxième zone transversale 16d traversant la pédale 15. La pédale est fixée à l'élément métallique par une liaison pivot selon un axe parallèle à l'axe transversal Y. Ainsi, la pédale peut être animée d'un mouvement de rotation autour de l'axe Y2 tout en demeurant sensiblement horizontale. Une position haute de la pédale correspond à une position active du dispositif de freinage, dans laquelle ses branches 16a, 16b s'étendent vers le bas. Une position basse de la pédale correspond à une position inactive du dispositif de freinage, dans laquelle ses branches 16a, 16b sont relevées pour éviter tout contact avec le sol. Enfin, l'élément métallique 16 possède une propriété élastique naturelle qui tend, en absence de sollicitation de la pédale, à positionner le dispositif de freinage dans sa position active. En variante, le frein peut comprendre tout ressort de rappel tendant à le rappeler en position active de freinage.The metal element 16 is symmetrical with respect to the plane of symmetry XZ and is rotatable relative to the base 11 along an axis Y2, shown in FIG. figure 10 , parallel to the transverse axis Y. To support this connection in rotation, the metal element comprises on each branch a transverse zone 16c adapted to cooperate with the base. The metal element also comprises a second transversal zone 16d crossing the pedal 15. The pedal is fixed to the metal element by a pivot connection along an axis parallel to the transverse axis Y. Thus, the pedal can be driven by a rotational movement around the Y2 axis while remaining substantially horizontal. A high position of the pedal corresponds to an active position of the braking device, in which its branches 16a, 16b extend downwards. A low position of the pedal corresponds to an inactive position of the braking device, in which its branches 16a, 16b are raised to avoid contact with the ground. Finally, the metal element 16 has a natural elastic property which tends, in the absence of biasing the pedal, to position the braking device in its active position. Alternatively, the brake may include any return spring tending to return it to the active braking position.

Le dispositif de verrouillage 9 est mobile entre une position de verrouillage, par exemple visible sur les figures 2 et 7, pour laquelle le dispositif de verrouillage est apte à maintenir le dispositif de freinage dans sa position inactive, et une position de déverrouillage, par exemple visible sur les figures 4 et 5, pour laquelle le dispositif de verrouillage ne maintient pas le dispositif de freinage dans sa position inactive. A cet effet, la pédale 15 comprend un crochet 17, visible notamment sur les figures 2, 3 et 10, réalisé dans le corps de la pédale et le dispositif de verrouillage 9 comprend un organe de verrouillage correspondant, sous forme d'un crochet 18, notamment visible sur les figures 2 et 3, mobile en liaison glissière selon l'axe longitudinal X. Les deux crochets 17, 18 sont aptes à coopérer pour maintenir le dispositif de freinage dans sa position inactive. Ainsi, on obtient une position inactive verrouillée du frein. Lorsque le dispositif de verrouillage 9 est en position de verrouillage, son crochet 18 est dans une position arrière dans laquelle il est apte à coopérer avec le crochet 17 de la pédale. Lorsque le dispositif de verrouillage 9 est en position de déverrouillage, son crochet 18 est dans une position avancée, dans laquelle il ne peut plus coopérer avec le crochet 17 de la pédale. Le dispositif de verrouillage 9 comprend en outre un ressort de rappel 19 exerçant un effort de rappel sur le crochet 18, tendant à le rappeler dans sa position arrière de verrouillage.The locking device 9 is movable between a locking position, for example visible on the figures 2 and 7 , for which the locking device is adapted to hold the braking device in its inactive position, and an unlocking position, for example visible on the figures 4 and 5 , for which the locking device does not keep the braking device in its inactive position. For this purpose, the pedal 15 comprises a hook 17, visible in particular on the Figures 2, 3 and 10 , made in the body of the pedal and the locking device 9 comprises a corresponding locking member, in the form of a hook 18, in particular visible on the Figures 2 and 3 movable in sliding connection along the longitudinal axis X. The two hooks 17, 18 are able to cooperate to maintain the braking device in its inactive position. Thus, an inactive locked position of the brake is obtained. When the locking device 9 is in the locking position, the hook 18 is in a rear position in which it is adapted to cooperate with the hook 17 of the pedal. When the locking device 9 is in the unlocking position, its hook 18 is in an advanced position, in which it can no longer cooperate with the hook 17 of the pedal. The locking device 9 further comprises a return spring 19 exerting a return force on the hook 18, tending to return it to its rear locking position.

Lorsque le crochet 18 du dispositif de verrouillage 9 est dans une position avancée, il ne se situe pas sur la trajectoire du crochet 17 de la pédale 15. La position active ou inactive du dispositif de freinage est alors commandée uniquement par un appui vertical sur la pédale 15, le dispositif de freinage est déverrouillé. Si la chaussure exerce un appui sur la pédale, les branches 16a, 16b du frein pivotent vers le haut et le dispositif de freinage est inactif. Si la chaussure n'exerce pas d'appui sur la pédale, la pédale remonte grâce à sa propriété élastique, les branches 16a, 16b du frein étant alors abaissées en position de freinage, et le dispositif de freinage est actif.When the hook 18 of the locking device 9 is in an advanced position, it is not in the path of the hook 17 of the pedal 15. The active or inactive position of the braking device is then controlled only by a vertical support on the pedal 15, the braking device is unlocked. If the shoe bears on the pedal, the branches 16a, 16b of the brake pivot upwards and the braking device is inactive. If the shoe does not exert support on the pedal, the pedal goes up thanks to its elastic property, the branches 16a, 16b of the brake being then lowered in the braking position, and the braking device is active.

Lorsque le crochet 18 du dispositif de verrouillage 9 est dans sa position arrière, il se situe sur la trajectoire du crochet 17 de la pédale 15. Tant que le dispositif de freinage est actif, les deux crochets 17, 18 ne sont pas en prise. Dès que le dispositif de freinage est en position inactive, par exemple suite à l'appui d'une chaussure sur la pédale 15, le crochet 18 peut crocheter le crochet 17 de la pédale 15. Lorsque les deux crochets 17, 18 coopèrent, c'est-à-dire qu'ils sont en prise l'un avec l'autre, la pédale 15 est maintenue dans sa position basse, et le dispositif de freinage 8 est par conséquent maintenu inactif.When the hook 18 of the locking device 9 is in its rear position, it is in the path of the hook 17 of the pedal 15. As long as the braking device is active, the two hooks 17, 18 are not engaged. As soon as the braking device is in the inactive position, for example following the support of a shoe on the pedal 15, the hook 18 can hook the hook 17 of the pedal 15. When the two hooks 17, 18 cooperate, that is, they are engaged with each other, the pedal 15 is held in its down position, and the braking device 8 is therefore kept inactive.

On peut indifféremment d'abord ramener la pédale en position basse puis déplacer le crochet 18 vers l'arrière ou bien d'abord déplacer le crochet 18 vers l'arrière puis ramener la pédale 15 en position basse pour faire coopérer les deux crochet 17, 18. Pour ce dernier cas de figure, les deux crochets comprennent chacun un chanfrein disposé de sorte que la mise en appui de leurs chanfreins respectifs provoque un déplacement élastique du crochet 18 du dispositif de verrouillage 9 vers l'avant pour permettre le passage du crochet 17 de la pédale sous ce crochet 18. Lorsque le crochet 17 de la pédale est passé sous le crochet 18, ce dernier reprend sa position vers l'arrière grâce à l'effet du ressort de rappel 19.We can indifferently first bring the pedal down and then move the hook 18 rearward or first move the hook 18 rearward and then bring the pedal 15 down to cooperate with the two hook 17, 18. For the latter case, the two hooks each comprise a chamfer arranged so that the bearing of their respective chamfers causes an elastic movement of the hook 18 of the locking device 9 forward to allow the passage of the hook 17 of the pedal under this hook 18. When the hook 17 of the pedal is passed under the hook 18, the latter takes up its position towards the rear thanks to the effect of the return spring 19.

En variante le dispositif de verrouillage 9 pourrait être agencé différemment. Par exemple, la position longitudinale des deux crochets 17, 18 pourrait être inversée. Le ressort de rappel 19 pourrait être supporté par la pédale. De plus, la liaison entre le crochet 18 et un organe d'actionnement 20, qui sera précisé plus loin, peut présenter différentes formes.Alternatively the locking device 9 could be arranged differently. For example, the longitudinal position of the two hooks 17, 18 could be reversed. The return spring 19 could be supported by the pedal. In addition, the connection between the hook 18 and an actuating member 20, which will be specified later, may have different shapes.

Le levier 10, représenté en figure 14, est mobile par rapport à l'agrippe talon 7 entre au moins une position de montée et une position de chaussage. Le levier est apte au cours de son déplacement de la position de montée à la position de chaussage, à déplacer le dispositif de verrouillage 9 de sa position de verrouillage vers sa position de déverrouillage. A cet effet, le dispositif de verrouillage 9 comprend un organe d'actionnement 20, particulièrement visible sur les figures 2, 4 et 10, solidaire du crochet 18, et apte à interagir avec le levier 10. Tout comme le crochet 18, l'organe d'actionnement 20 est également mobile en liaison glissière selon l'axe longitudinal X par rapport à l'embase. Pour ce faire, l'organe d'actionnement peut être logé dans une empreinte formée dans l'embase dont la forme permet le coulissement de l'organe d'actionnement selon l'axe longitudinal X. Le levier 10 est mobile par rapport à l'agrippe talon 7 et par rapport à l'embase 11 selon une liaison pivot d'axe Y3. Le levier peut être un élément monobloc, préférentiellement réalisé à partir de plastique injecté. En variante, le levier peut être formé à partir de deux pièces ou encore d'avantage de pièces fixées rigidement entre elles.Lever 10, shown in figure 14 , is movable relative to the gripping bead 7 between at least one mounting position and a stopping position. The lever is adapted during its movement from the climbing position to the stopping position, to move the locking device 9 from its locking position to its unlocking position. For this purpose, the locking device 9 comprises an actuating member 20, particularly visible on the figures 2 , 4 and 10 , integral with the hook 18, and able to interact with the lever 10. Just like the hook 18, the actuating member 20 is also movable in sliding connection along the longitudinal axis X relative to the base. To do this, the actuating member may be housed in a recess formed in the base whose shape allows the sliding of the actuating member along the longitudinal axis X. The lever 10 is movable relative to the Heel catch 7 and relative to the base 11 according to a pivot connection of axis Y3. The lever may be a monoblock element, preferably made from injected plastic. Alternatively, the lever can be formed from two pieces or more advantageously of parts fixed rigidly between them.

Selon le mode de réalisation, le levier 10 entoure l'agrippe talon à gauche et à droite, par deux flancs 21a, 21b, visibles sur la figure 12, orientés sensiblement parallèlement à l'axe longitudinal X et à l'axe vertical Z. Ces deux flans 21a, 21b sont eux-mêmes entourés des ailettes verticales 30a, 30b de l'embase 11. Ces deux flancs sont reliés à leur extrémité supérieure par un pont 22 apte à passer au dessus de l'agrippe talon 7. Le pont 22 peut avoir une forme ergonomique apte à un actionnement manuel ou à un actionnement par l'intermédiaire d'un bâton de ski. En particulier, comme cela est visible sur la figure 8, le pont 22 comprend une cavité 22a apte à recevoir l'appui de la pointe d'un bâton pour pousser sur le levier. Le pont 22 comprend également une ouverture 22b semi circulaire à son extrémité arrière apte à accueillir le manche d'un bâton pour pousser le levier, une rondelle du bâton passant alors sous le levier. Les deux flancs 21a, 21b comprennent chacun une ouverture 23 supportant l'axe Y3 de rotation et une came d'actionnement 24. L'axe Y3 est situé dans une partie inférieure du levier 10 et les deux cames 24 sont situées en contrebas de l'axe Y3 de rotation du levier, aux extrémités inférieures de chaque flanc 21a, 21b.According to the embodiment, the lever 10 surrounds the gripping heel left and right, by two sides 21a, 21b, visible on the figure 12 , oriented substantially parallel to the longitudinal axis X and to the vertical axis Z. These two blanks 21a, 21b are themselves surrounded by the vertical fins 30a, 30b of the base 11. These two flanks are connected at their upper end by a bridge 22 adapted to pass over the gripping heel 7. The bridge 22 may have an ergonomic shape adapted to manual actuation or actuation by through a ski pole. In particular, as is visible on the figure 8 , the bridge 22 comprises a cavity 22a adapted to receive the support of the tip of a stick to push on the lever. The bridge 22 also comprises a semi-circular aperture 22b at its rear end adapted to receive the handle of a stick to push the lever, a washer of the stick then passing under the lever. The two sides 21a, 21b each comprise an opening 23 supporting the axis Y3 of rotation and an actuating cam 24. The axis Y3 is located in a lower part of the lever 10 and the two cams 24 are located below the Y3 axis of rotation of the lever, at the lower ends of each flank 21a, 21b.

En fonction de l'orientation du levier 10, les deux cames 24 exercent ou non un appui sur l'organe d'actionnement 20. Dans la position de montée intermédiaire du levier 10, l'élément de maintien arrière étant en configuration de montée, représentée sur les figures 2 et 3, les deux cames 24 n'appuient pas sur l'organe d'actionnement 20. La position de l'organe d'actionnement 20 (et du crochet 18 qui lui est solidaire) est donc uniquement imposée par l'effet du ressort de rappel 19. Le crochet 18 est alors positionné vers l'arrière, c'est-à-dire en direction du crochet 17 de la pédale 15, dans une configuration où il peut remplir sa fonction de verrouillage du dispositif de freinage. Dans le passage de la position de montée à la position de chaussage plus en arrière du levier, l'élément de maintien arrière venant alors en configuration de chaussage, représentée sur la figure 4, les deux cames 24 exercent un appui sur l'organe d'actionnement 20 vers l'avant, orienté selon l'axe longitudinal X, à l'encontre du ressort de rappel. L'organe d'actionnement 20 est ainsi translaté vers l'avant, entrainant le crochet 18 de même vers l'avant, et le dispositif de verrouillage se trouve alors déplacé en position de déverrouillage. La position de chaussage du levier correspond à une position du levier abaissé vers l'arrière. La position de montée du levier correspond à une position intermédiaire, partiellement redressée vers l'avant. Comme cela sera précisé par la suite, lors de son passage de la position de montée vers la position de chaussage, entrainant le passage de la configuration de montée vers la configuration de chaussage, le levier 10 agit sur le dispositif de verrouillage, de sorte à induire un déplacement suffisant, selon une translation longitudinale dans ce mode de réalisation, afin de le positionner dans sa position de déverrouillage, position qui est ensuite maintenue par l'agrippe talon, voire par le levier lui-même. De plus, comme cela sera précisé, le levier 10 du mode de réalisation peut comprendre une troisième position relevée, sensiblement verticale, dans la configuration de descente et/ou de montée avec cale de l'élément de maintien arrière.Depending on the orientation of the lever 10, the two cams 24 or not bear on the actuating member 20. In the intermediate up position of the lever 10, the rear holding element being in a climb configuration, represented on the Figures 2 and 3 the two cams 24 do not press on the actuating member 20. The position of the actuating member 20 (and the hook 18 which is secured thereto) is therefore only imposed by the effect of the return spring 19. The hook 18 is then positioned rearward, that is to say in the direction of the hook 17 of the pedal 15, in a configuration where it can fulfill its locking function of the braking device. In the passage from the climbing position to the footwear position further rearward of the lever, the rear holding element then coming into the boot configuration, shown in FIG. figure 4 the two cams 24 bear on the actuating member 20 towards the front, oriented along the longitudinal axis X, against the return spring. The actuating member 20 is thus translated forward, causing the hook 18 to the same forwards, and the locking device is then moved to the unlocking position. The lever position of the lever corresponds to a position of the lever lowered to the rear. The lever up position corresponds to an intermediate position, partially straightened forward. As will be specified later, during its passage from the climbing position to the stitching position, causing the passage of the climbing configuration to the boot configuration, the lever 10 acts on the locking device, so as to inducing a sufficient movement, according to a longitudinal translation in this embodiment, to position it in its unlocked position, which position is then maintained by the gripping bead, or even by the lever itself. In addition, as will be appreciated, the lever 10 of the embodiment may include a third raised, substantially vertical, position in the descent and / or shimmed configuration of the rear holding member.

L'organe d'actionnement 20 se présente sous la forme d'une fourche disposée globalement horizontalement, particulièrement visible sur la figure 10. L'organe d'actionnement 20 comprend un bras 20a vers l'avant portant l'organe de verrouillage, c'est-à-dire le crochet 18 dans le mode de réalisation, parallèle à l'axe longitudinal X, sensiblement au milieu de l'élément de maintien arrière 4. Le bras 20a interagit avec le ressort de rappel 19 et supporte l'organe de verrouillage en forme de crochet 18 à son extrémité avant. Le ressort de rappel 19 est logé dans un évidement longitudinal et cylindrique du bras 20a. Il est en appui d'une part contre une face 25 transversale et verticale de l'embase 11 et d'autre part contre le fond de l'évidement du bras 20a. L'organe d'actionnement 20 comprend de plus deux pattes 20b latérales orientées vers l'arrière, parallèles à l'axe longitudinal X, et aptes à coopérer avec les deux cames 24 du levier 10.The actuating member 20 is in the form of a fork disposed generally horizontally, particularly visible on the figure 10 . The actuating member 20 comprises a forward arm 20a carrying the locking member, that is to say the hook 18 in the embodiment, parallel to the longitudinal axis X, substantially in the middle of the rear holding element 4. The arm 20a interacts with the return spring 19 and supports the hook-shaped locking member 18 at its front end. The return spring 19 is housed in a longitudinal and cylindrical recess of the arm 20a. It is supported on the one hand against a transverse and vertical face of the base 11 and on the other hand against the bottom of the recess of the arm 20a. The actuating member 20 further comprises two rearwardly facing tabs 20b parallel to the longitudinal axis X and able to cooperate with the two cams 24 of the lever 10.

En variante, une seule patte 20b suffirait pour actionner l'organe d'actionnement. L'organe d'actionnement 20 comprend également une patte centrale 20c également orientée vers l'arrière, apte à coopérer avec une surface de butée 26 disposée à l'avant de l'agrippe talon 7. Lorsque l'agrippe talon 7 est en position de maintien, la surface de butée 26 exerce un appui sur la patte centrale 20c orienté selon l'axe longitudinal X à l'encontre du ressort de rappel 19. Ainsi, la surface de butée 26 peut maintenir ou participer au maintien du dispositif de verrouillage 9 dans sa position de déverrouillage. En remarque, en position de chaussage du levier, l'agrippe talon est en position ouverte et le levier 10 maintient seul le dispositif de verrouillage 9 dans sa position de déverrouillageAlternatively, a single leg 20b would be sufficient to actuate the actuating member. The actuating member 20 also comprises a central lug 20c also oriented towards the rear, adapted to cooperate with an abutment surface 26 disposed at the front of the heel gripper 7. When the heel gripper 7 is in position holding, the abutment surface 26 bears on the central lug 20c oriented along the longitudinal axis X against the return spring 19. Thus, the abutment surface 26 can maintain or participate in maintaining the locking device 9 in its unlocking position. As a remark, in the lever position of the lever, the heel grip is in the open position and the lever 10 maintains only the locking device 9 in its unlocked position

Le levier 10 peut alors être déplacé de sa position de chaussage arrière vers toute autre position sans que le dispositif de verrouillage 9 ne bascule dans sa position de verrouillage. La surface de butée 26 est positionnée sur l'agrippe talon 7 de sorte à ce que, en position ouverte de l'agrippe talon, elle n'exerce aucun appui sur la patte centrale 20c. La patte centrale 20c est disposée verticalement et comprend une face d'appui verticale et transversale apte à coopérer avec la surface de butée 26. Lorsque l'agrippe talon 7 est basculé dans sa position de maintien, la surface de butée 26 descend vers le bas et vient en appui contre la face d'appui de la patte centrale 20c. L'organe d'actionnement 20 ne peut alors plus reculer et le dispositif de verrouillage 9 est maintenu dans sa position de déverrouillage.The lever 10 can then be moved from its rear seating position to any other position without the locking device 9 tilting in its locking position. The abutment surface 26 is positioned on the heel gripper 7 so that, in the open position of the heel gripping, it does not exert any support on the central lug 20c. The central lug 20c is arranged vertically and comprises a vertical and transverse bearing face adapted to cooperate with the abutment surface 26. When the heel catch 7 is tilted in its holding position, the abutment surface 26 descends downwards. and bears against the bearing face of the central leg 20c. The actuating member 20 can then no longer move back and the locking device 9 is held in its unlocking position.

Selon le mode de réalisation présenté, le levier 10 est mobile jusqu'à une troisième position relevée sensiblement verticale, représentée par les figures 5 à 7. Dans cette position le pont 22 reliant les deux flancs du levier 10 est sensiblement à l'aplomb de l'axe Y3 de rotation du levier. Chaque flanc comprend une protubérance 27 vers l'avant positionnée sur la trajectoire T1 du trottoir lorsque le skieur marche avec le ski. Dans cette position relevée, le levier 10 forme une cale d'aide à la montée pour le talon de la chaussure. Le levier présente donc des protubérances 27 qui passent sur les côtés de la chaussure, permettant d'éviter le contact entre le levier dans la position relevée et le talon de la chaussure en phase de descente, c'est-à-dire lorsque le talon est plaqué sur l'embase avec l'agrippe talon en position de maintien. Ainsi la position relevée du levier peut être aussi bien utilisée en phase de montée avec cale et en phase de descente, c'est-à-dire dans les configurations de montée avec cale et de descente de l'élément de maintien arrière.According to the embodiment presented, the lever 10 is movable to a third raised position substantially vertical, represented by the Figures 5 to 7 . In this position the bridge 22 connecting the two sides of the lever 10 is substantially in line with the axis Y3 of rotation of the lever. Each flank comprises a forward protrusion 27 positioned on the trajectory T1 of the sidewalk when the skier is walking with the ski. In this raised position, the lever 10 forms a wedge of help to the rise for the heel of the shoe. The lever thus has protrusions 27 which pass on the sides of the shoe, to avoid contact between the lever in the raised position and the heel of the shoe during the descent phase, that is to say when the heel is pressed onto the base with the heel grip in the holding position. Thus, the raised position of the lever can be used both in the climbing phase with shim and in the descent phase, that is to say in the climbing configurations with shim and descent of the rear holding element.

L'élément de maintien arrière 4 comprend également une pédale de chaussage 35, particulièrement visible sur les figures 10, 11 et 15, mobile par rapport à l'agrippe talon 7 et par rapport à l'embase 11 entre deux ou trois positions. Notamment, elle occupe une position de chaussage, représentée sur les figures 10, 11 et 15, en configuration de chaussage de l'élément de maintien arrière, dans laquelle elle est apte à recevoir l'appui du talon d'une chaussure lors d'une phase de chaussage, appui qui entraine en rotation vers le bas l'agrippe talon 7, jusqu'à la configuration de descente de l'élément de maintien arrière. Elle occupe de plus une position escamotée, relevée vers le haut, représentée sur les figures 3 et 7, en configuration de montée et de montée avec cale de l'élément de maintien arrière, dans laquelle elle est remontée sous le bord 7a de l'agrippe talon 7, de sorte à ne plus se trouver sur la trajectoire d'une chaussure. Dans le mode de réalisation, la pédale de chaussage 35 est articulée sur l'agrippe talon 7. Elle se présente sous la forme d'un fil métallique plié en forme de « U ». Une portion transversale 35a de la pédale de chaussage forme la base du « U » et est disposée vers l'avant. La portion transversale 35a est prolongée de part et d'autre par deux branches 35b articulées en rotation sur l'agrippe talon. La pédale de chaussage 35 est soumise à un ressort de rappel tendant à la positionner dans sa position escamotée. Le levier 10 comprend une came 44, visible sur la figure 15, qui agit sur la pédale de chaussage pour provoquer sa rotation vers le bas à l'encontre du ressort de rappel, notamment pour atteindre sa position de chaussage, lors du passage en configuration de chaussage de l'élément de maintien arrière par l'actionnement du levier 10.The rear holding element 4 also comprises a foot pedal 35, particularly visible on the Figures 10, 11 and 15 movable relative to the heel gripping 7 and relative to the base 11 between two or three positions. In particular, she occupies a boot position, represented on the Figures 10, 11 and 15 , in the boot configuration of the rear holding element, in which it is adapted to receive the support of the heel of a boot during a boot phase, support which causes the heel gripper to rotate downwards 7 until the descent configuration of the rear holding element. It also occupies a retracted position, raised upwards, represented on the figures 3 and 7 , in climbing configuration and climbing with wedge of the rear holding element, in which it is raised under the edge 7a of the heel gripper 7, so as not to be in the path of a shoe. In the embodiment, the foot pedal 35 is articulated on the heel gripper 7. It is in the form of a bent metal wire shaped "U". A transverse portion 35a of the foot pedal forms the base of the "U" and is disposed forward. The transverse portion 35a is extended on either side by two branches 35b articulated in rotation on the heel gripper. The pedal of boot 35 is subjected to a return spring tending to position it in its retracted position. The lever 10 comprises a cam 44, visible on the figure 15 , which acts on the foot pedal to cause its downward rotation against the return spring, in particular to reach its stance position, when passing in the boot configuration of the rear holding element by the actuation lever 10.

L'élément de maintien arrière est apte à prendre diverses configurations C1, C2, C3, C4 correspondant à différentes phases d'utilisation du ski.The rear holding element is adapted to take various configurations C1, C2, C3, C4 corresponding to different phases of use of the ski.

Dans une configuration de montée C1 illustrée sur les figures 2, 3, 8 et 9, le levier 10 est dans sa position de montée dans une position intermédiaire partiellement relevée, l'agrippe talon 7 est dans sa position ouverte, le dispositif de verrouillage 9 est dans sa position de verrouillage, la pédale de chaussage 35 est dans une position escamotée et le dispositif de freinage 8 est en position inactive verrouillée. Cette configuration correspond à une phase d'utilisation du ski en montée. On remarque que si préalablement à cette configuration, le dispositif de freinage est actif, il suffit d'exercer un appui avec la chaussure sur la pédale pour mettre en prise les deux crochets du dispositif de verrouillage et ainsi maintenir le dispositif de freinage en position inactive. Ainsi, le dispositif de freinage n'entrave pas la marche du skieur.In a C1 climb configuration illustrated on the Figures 2, 3 , 8 and 9 , the lever 10 is in its upward position in a partially raised intermediate position, the heel grip 7 is in its open position, the locking device 9 is in its locking position, the foot pedal 35 is in a retracted position and the braking device 8 is in the locked inactive position. This configuration corresponds to a phase of use of the ski uphill. Note that if prior to this configuration, the braking device is active, simply exert a support with the shoe on the pedal to engage the two hooks of the locking device and thus keep the braking device in the inactive position . Thus, the braking device does not hinder the skier's progress.

Dans une configuration de chaussage C2, illustrée sur les figures 4, 10 et 11, le levier 10 est dans sa position de chaussage basculé vers l'arrière, l'agrippe talon 7 est dans sa position ouverte, la pédale 15 du frein est en position haute, la pédale de chaussage 35 est dans une position abaissée et le dispositif de verrouillage 9 est dans sa position de déverrouillage. Une telle configuration correspond à un état du ski préalable à la phase de descente, dans lequel le skieur s'apprête à chausser le ski, c'est-à-dire s'apprête à faire basculer l'agrippe talon de sa position ouverte à sa position de maintien contre le trottoir de la chaussure. Dans cette configuration, le dispositif de freinage 8 est naturellement en position active puisque le dispositif de verrouillage est déverrouillé.In a configuration of footwear C2, illustrated on figures 4 , 10 and 11 the lever 10 is in its retracted position, the heel grip 7 is in its open position, the brake pedal 15 is in the up position, the foot pedal 35 is in a lowered position and the device locking 9 is in its unlocking position. Such a configuration corresponds to a state of skiing prior to the phase of downhill, in which the skier is preparing to put the ski, that is to say, is about to tilt the heel grip from its open position to its holding position against the sidewalk of the shoe. In this configuration, the braking device 8 is naturally in the active position since the locking device is unlocked.

Dans une configuration de descente C3, illustrée sur les figures 5 et 6, le levier 10 est dans la troisième position relevée vers l'avant ou position avant, l'agrippe talon 7 est dans sa position de maintien, le dispositif de verrouillage 9 est dans sa position de déverrouillage, le dispositif de freinage 8 est en position inactive car une chaussure (non représentée sur les figures 5 et 6) est en appui sur la pédale. Toutefois, si le skieur venait à déchausser, par exemple consécutivement à une chute ou à un déchaussage volontaire, le dispositif de freinage passerait automatiquement en position active car le dispositif de verrouillage est en position de déverrouillage.In a C3 descent configuration, illustrated on the Figures 5 and 6 , the lever 10 is in the third position raised forwards or forward position, the heel gripper 7 is in its holding position, the locking device 9 is in its unlocking position, the braking device 8 is in position inactive because a shoe (not shown on the Figures 5 and 6 ) is pressing on the pedal. However, if the skier were to remove, for example following a fall or a voluntary release, the braking device would automatically go into the active position because the locking device is in the unlocked position.

Dans une configuration de montée avec cale C4, illustrée sur la figure 7, le levier 10 est dans la position relevée vers l'avant ou position avant, l'agrippe talon 7 est dans sa position ouverte, le dispositif de verrouillage 9 est dans sa position de verrouillage et le dispositif de freinage 8 est en position inactive. Cette configuration correspond à une phase de montée avec utilisation du levier 10 comme cale de montée. Cette configuration est donc très proche de la configuration de montée à l'exception de la position du levier 10. Le skieur peut facilement passer de la configuration de montée à la configuration de montée avec cale et inversement en manipulant le levier 10.
Les positions du levier 10 de montée avec cale et de descente correspondent ici à la position la plus relevée vers l'avant et sont similaires dans le mode de réalisation présenté mais en variante, la position de montée avec cale pourrait être différente et en particulier encore plus relevée vers l'avant.In a climb configuration with C4 shim, illustrated on the figure 7 , the lever 10 is in the raised position forward or forward position, the heel gripper 7 is in its open position, the locking device 9 is in its locking position and the braking device 8 is in the inactive position. This configuration corresponds to a rising phase with use of the lever 10 as a climbing wedge. This configuration is therefore very close to the climb configuration with the exception of the position of the lever 10. The skier can easily switch from the climb configuration to the climbing configuration with shim and vice versa by manipulating the lever 10.
The positions of the up and down lever 10 correspond here to the highest position forward and are similar in the embodiment shown but alternatively the position of climb with wedge could be different and especially even more raised forward.

Selon le mode de réalisation explicité précédemment, il apparait donc que le levier 10 remplit une première fonction d'actionnement du dispositif de verrouillage, permettant son passage automatique de la position de verrouillage à la position de déverrouillage lorsqu'il est tourné vers l'avant.According to the embodiment explained above, it therefore appears that the lever 10 fills a first actuating function of the locking device, allowing its automatic passage from the locking position to the unlocking position when it is turned forwards. .

En complément de la description précédente, le levier 10 selon le mode de réalisation remplit une deuxième fonction d'actionnement automatique de l'agrippe talon 7. Pour cela, le levier 10 comprend également un moyen d'interaction avec l'agrippe talon. Selon le mode de réalisation, ce moyen d'interaction comprend une came 54, représentée sur la figure 15. Plus exactement, deux cames 54 sont agencées sur les deux flancs latéraux du levier 10. Notamment, lorsque le levier 10 est dans sa position de chaussage arrière, il maintient l'agrippe talon 7 dans sa position ouverte. Lorsque l'agrippe talon 7 est en prise avec une chaussure, dans la configuration de descente C3 de l'élément de maintien arrière, le levier 10 est dans sa position relevée. Pour déchausser, c'est-à-dire pour libérer le trottoir d'une chaussure de l'emprise de l'agrippe talon 7, un skieur peut simplement manipuler le levier 10 vers la position de chaussage ou de montée, ce qui entraine un basculement de l'agrippe talon 7 de sa position de maintien à sa position ouverte. Le levier 10 est ainsi un levier de déchaussage.In addition to the foregoing description, the lever 10 according to the embodiment fulfills a second function of automatic actuation of the heel gripper 7. For this, the lever 10 also comprises a means of interaction with the heel gripper. According to the embodiment, this interaction means comprises a cam 54, represented on the figure 15 . More exactly, two cams 54 are arranged on the two lateral flanks of the lever 10. In particular, when the lever 10 is in its rear shoeing position, it keeps the heel gripper 7 in its open position. When the heel gripper 7 is in engagement with a boot, in the lowering configuration C3 of the rear holding member, the lever 10 is in its raised position. To remove, that is to say to release the sidewalk of a shoe from the grip of the gripping heel 7, a skier can simply manipulate the lever 10 to the position of putting on or climb, which causes a tilting of the heel gripper 7 from its holding position to its open position. The lever 10 is thus a heaving lever.

Ainsi, comme mentionné précédemment, le levier 10 cumule différentes fonctions : premièrement, il est apte à commander le dispositif de verrouillage, deuxièmement, il est apte à faire basculer l'agrippe talon dans sa position ouverte et troisièmement, il est apte à former une cale d'aide à la montée. En variante, cette troisième fonction pourrait être optionnelle.Thus, as mentioned above, the lever 10 has various functions: first, it is able to control the locking device, secondly, it is able to tilt the bale gripper in its open position and third, it is able to form a hold help with climbing. Alternatively, this third function could be optional.

En complément, comme explicité précédemment, le levier 10 commande aussi le positionnement de la pédale de chaussage 35 de l'élément de maintien arrière. Dans une position dite de chaussage, la pédale de chaussage 35 est apte à être actionnée par une chaussure de ski. La portion transversale 35a est alors positionnée environ à mi hauteur entre l'embase 11 et le bord 7a de l'agrippe talon. La portion transversale est positionnée sur la trajectoire du talon de la chaussure lorsque la chaussure est fixée à l'élément de maintien avant. Cette position de la pédale de chaussage 35 est obtenue lorsque l'élément de maintien arrière est dans la configuration de chaussage C2. Lorsque le skieur exerce un appui sur la pédale de chaussage 35, l'agrippe talon 7 bascule de sa position ouverte à sa position de maintien.In addition, as explained above, the lever 10 also controls the positioning of the foot pedal 35 of the rear holding element. In a so-called boot position, the foot pedal 35 is able to be actuated by a ski boot. The transverse portion 35a is then positioned at about halfway between the base 11 and the edge 7a of the heel gripper. The transverse portion is positioned on the path of the heel of the shoe when the shoe is attached to the front holding member. This position of the foot pedal 35 is obtained when the rear holding element is in the configuration of footwear C2. When the skier presses the foot pedal 35, the heel catch 7 moves from its open position to its holding position.

Consécutivement au basculement de l'agrippe talon de sa position ouverte à sa position de maintien, la pédale de chaussage 35 descend dans une première position de repos basculée vers le bas, contre l'embase, comme représenté par exemple sur la figure 6 en configuration de descente. Dans cette position la portion transversale 35a est noyée dans un logement du repose talon 14 surmontant l'embase. La portion transversale se situe alors sous la semelle d'une chaussure en phase de descente, c'est-à-dire en prise avec l'agrippe talon.As a result of the tilting of the heel grip from its open position to its holding position, the foot pedal 35 descends in a first rest position tilted downwards, against the base, as represented for example on the figure 6 in descent configuration. In this position the transverse portion 35a is embedded in a housing of the heel rest 14 surmounting the base. The transverse portion is then under the sole of a shoe in the descent phase, that is to say, in engagement with the gripping heel.

La pédale de chaussage 35 peut également prendre une deuxième position escamotée, basculée vers le haut, contre l'agrippe talon. Dans cette position la portion transversale est basculée vers le haut et se positionne directement sous le bord 7a de l'agrippe talon qui est alors en position ouverte. Une telle position de la pédale de chaussage correspond à la configuration de montée C1 de l'élément de maintien arrière et est particulièrement visible sur les figures 2, 3, 8 et 9. La pédale de chaussage est ainsi positionnée hors de la trajectoire T1 du talon de la chaussure lorsque le ski est utilisé en phase de montée, c'est-à-dire lorsque la chaussure n'est fixée que par l'élément de maintien avant. La pédale de chaussage 35 n'est donc pas apte à être actionnée par une chaussure de ski et ne gêne pas le mouvement de basculement de la chaussure (trajectoire T1), le talon de la chaussure pouvant alors venir au contact de l'embase 11.The foot pedal 35 can also take a second retracted position, tilted upwards against the heel grip. In this position the transverse portion is tilted upwards and is positioned directly under the edge 7a of the heel gripper which is then in the open position. Such a position of the foot pedal corresponds to the rising configuration C1 of the rear holding element and is particularly visible on the Figures 2, 3 , 8 and 9 . The foot pedal is thus positioned outside the trajectory T1 of the heel of the shoe when the ski is used in the climbing phase, that is to say when the shoe is fixed only by the front holding element. The foot pedal 35 is not able to be actuated by a ski boot and does not interfere with the tilting movement of the shoe (T1 trajectory), the heel of the shoe can then come into contact with the base 11 .

Comme expliqué précédemment, le levier 10 est mobile en rotation entre trois positions arrière, avant et relevée. Ces positions peuvent se distinguer par une rotation du levier 10 selon une amplitude supérieure ou égale à 45 degrés entre les positions de montée et de chaussage, de préférence supérieure ou égale à 60 degrés. Afin de marquer, c'est-à-dire d'identifier distinctement chacune de ces trois positions, l'élément de maintien arrière 4 comprend un mécanisme d'indexation. Le mécanisme d'indexation comprend deux ergots d'indexation 28 solidaires de l'embase, disposés chacun de part et d'autre de l'embase 11, et plus précisément sur les faces internes des ailettes latérales 30a, 30b de l'embase 11, et deux contre-formes 29, aptes à coopérer avec les deux ergots d'indexation. Chacune des contre-formes 29 sont creusées dans chaque flanc 21a, 21b des surfaces extérieures du levier 10. En variante, les ergots d'indexation pourraient être sur le levier et les contre-formes être sur l'embase. Le mécanisme d'indexation pourrait également ne comprendre qu'un seul ergot coopérant avec une seule contre-forme disposée à gauche ou à droite.As explained above, the lever 10 is rotatable between three rear, forward and raised positions. These positions can be distinguished by a rotation of the lever 10 at an amplitude greater than or equal to 45 degrees between the climbing and seating positions, preferably greater than or equal to 60 degrees. In order to mark, that is to say to identify distinctly each of these three positions, the rear holding element 4 comprises an indexing mechanism. The indexing mechanism comprises two indexing lugs 28 integral with the base, each disposed on either side of the base 11, and more precisely on the inner faces of the lateral fins 30a, 30b of the base 11. and two counter-forms 29, able to cooperate with the two indexing lugs. Each of the counterforms 29 are hollowed in each side 21a, 21b of the outer surfaces of the lever 10. Alternatively, the indexing lugs could be on the lever and against the forms be on the base. The indexing mechanism could also include only one lug cooperating with a single counter-shape arranged to the left or right.

Selon le mode de réalisation, l'embase 11, particulièrement visible sur la figure 13, comprend une paroi formant des ailettes verticales 30a, 30b latérales de forme globalement circulaire et s'étendant selon un plan longitudinal et vertical. La paroi est munie d'une ouverture 31 supportant l'axe Y3 de rotation du levier 10 et l'axe de rotation de l'agrippe talon 7. La paroi comprend une face intérieure tournée vers un plan médian de la fixation et une face extérieure, tournée vers l'extérieur du sous-élément. L'ergot d'indexation est un relief s'étendant verticalement de part et d'autre de l'ouverture 31. L'ergot d'indexation est en saillie par rapport à la face intérieure de la paroi des ailettes verticales 30a, 30b. L'ergot peut avoir par exemple la forme d'une portion de cylindre. Comme visible sur la figure 14, la contre-forme comprend trois renfoncements 29a, 29b, 29c. Chaque renfoncement à une forme complémentaire de l'ergot d'indexation. Les trois renfoncements sont répartis sur une face extérieure du flanc du levier autour de l'axe Y3. Les renfoncements sont séparés par des angles correspondant aux angles de positionnement du levier. Ainsi pour chacune des trois positions de montée, de chaussage, et relevée du levier, l'ergot d'indexation est en vis-à-vis d'un des trois renfoncements. Lorsque le levier est manipulé entre deux positions adjacentes, l'ergot sort d'un des renfoncements, glisse le long du flanc puis rentre à nouveau dans un renfoncement adjacent.According to the embodiment, the base 11, particularly visible on the figure 13 , comprises a wall forming vertical fins 30a, 30b side of generally circular shape and extending along a longitudinal and vertical plane. The wall is provided with an opening 31 supporting the axis Y3 of rotation of the lever 10 and the axis of rotation of the heel gripper 7. The wall comprises an inner face facing a median plane of the attachment and an outer face , turned towards the outside of the sub-element. The indexing lug is a relief extending vertically on either side of the opening 31. The indexing lug protrudes from the inner face of the wall of the vertical vanes 30a, 30b. The lug may have for example the shape of a cylinder portion. As visible on the figure 14 the counterform comprises three recesses 29a, 29b, 29c. Each recess has a shape complementary to the indexing pin. The three recesses are distributed on an outer face of the side of the lever around the axis Y3. The recesses are separated by angles corresponding to the positioning angles of the lever. Thus for each of the three positions of rise, donnage, and raised the lever, the indexing lug is vis-à-vis one of the three recesses. When the lever is manipulated between two adjacent positions, the lug emerges from one of the recesses, slides along the sidewall and then returns to an adjacent recess.

Une déformation élastique ou un déplacement élastique du levier 10 ou de l'embase selon l'axe transversal Y est donc requis pour permettre la transition entre lesdites trois positions du levier. Pour obtenir cet effet, chaque flanc est relié à l'embase par un moyen élastique orienté transversalement, c'est-à-dire agissant élastiquement selon la direction transversale Y. En l'occurrence, selon le mode de réalisation illustré sur la figure 12, le moyen élastique comprend une vis 32, un écrou 33 et une rondelle Belleville 34, ou plus généralement une rondelle ressort, agencés transversalement selon l'axe Y3 et déformables élastiquement selon l'axe Y3. La vis comprend une tête plate et un axe traversant l'ouverture 23 du flanc du levier et l'ouverture 31 des ailettes verticales 30a, 30b de l'embase. La face extérieure de la paroi comprend un logement circulaire 37 à l'intérieur duquel est logée la rondelle Belleville. La tête de vis est en appui sur la face extérieure de la paroi de l'embase, à l'extérieur du logement circulaire 37. La rondelle Belleville est en appui d'une part contre la tête de vis et d'autre part contre la paroi de l'embase. La hauteur du logement circulaire 37 selon l'axe transversal Y est définie de sorte que la rondelle Belleville soit comprimée à une hauteur donnée et produise un effort de réaction donné. L'effort produit par la rondelle Belleville est indépendant du niveau de serrage de la vis car celle-ci est en appui à l'extérieur du logement circulaire 34. La compression de la rondelle Belleville dépend de la hauteur du logement circulaire 37 mais ne dépend pas de la tension de serrage de la vis. Pour résumer, la rondelle Belleville est intercalée entre la tête de vis et la paroi de l'embase. La rondelle Belleville est intercalée entre les deux pièces indexées l'une par rapport à l'autre, c'est-à-dire entre une partie du levier 10 et une partie de l'embase 11. La paroi de l'embase est intercalée entre la rondelle Belleville et le flanc du levier. Le flanc du levier est intercalé entre la paroi de l'embase et l'écrou 33.An elastic deformation or an elastic displacement of the lever 10 or the base along the transverse axis Y is required to allow the transition between said three positions of the lever. To obtain this effect, each sidewall is connected to the base by an elastic means oriented transversely, that is to say acting elastically in the transverse direction Y. In this case, according to the embodiment illustrated in FIG. figure 12 , the elastic means comprises a screw 32, a nut 33 and a Belleville washer 34, or more generally a spring washer, arranged transversely along the axis Y3 and elastically deformable along the axis Y3. The screw comprises a flat head and an axis passing through the opening 23 of the flank of the lever and the opening 31 of the vertical fins 30a, 30b of the base. The outer face of the wall comprises a circular housing 37 inside which is housed the Belleville washer. The screw head is supported on the outer face of the wall of the base, outside the circular housing 37. The Belleville washer is supported on the one hand against the screw head and on the other hand against the wall of the base. The height of the circular housing 37 along the transverse axis Y is defined so that the Belleville washer is compressed at a given height and produces a given reaction force. The force produced by the Belleville washer is independent of the tightening level of the screw because it is supported outside the circular housing 34. The compression of the Belleville washer depends on the height of the circular housing 37 but does not depend no tightening tension of the screw. To summarize, the Belleville washer is inserted between the screw head and the wall of the base. The Belleville washer is interposed between the two parts indexed relative to each other, that is to say between a portion of the lever 10 and a portion of the base 11. The wall of the base is interposed between the Belleville washer and the side of the lever. The sidewall of the lever is interposed between the wall of the base and the nut 33.

La position de l'ergot d'indexation à l'intérieur d'un renfoncement correspond à une position de moindre tension dans la rondelle Belleville. Une telle position est donc stable. La position de l'ergot d'indexation entre deux renfoncements correspond à une position de plus grande tension dans la rondelle Belleville, c'est-à-dire dans laquelle la rondelle Belleville est comprimée dans une direction selon l'axe Y3. Une telle position est donc instable. Ainsi, le mécanisme d'indexation permet de ressentir les positions du levier dans lesquelles l'ergot d'indexation coïncide avec un renfoncement, c'est-à-dire les positions de montée, de chaussage et relevée. L'avantage de cette solution est de permettre d'obtenir trois positions stables du levier, en évitant les changements de positions intempestifs du levier, ainsi que son usure prématurée par des frottements importants.The position of the indexing lug inside a recess corresponds to a position of lower tension in the Belleville washer. Such a position is therefore stable. The position of the indexing lug between two recesses corresponds to a position of greater tension in the Belleville washer, that is to say in which the Belleville washer is compressed in a direction along the axis Y3. Such a position is therefore unstable. Thus, the indexing mechanism makes it possible to feel the positions of the lever in which the indexing pin coincides with a recess, that is to say the positions of rise, footing and raised. The advantage of this solution is to make it possible to obtain three stable positions of the lever, avoiding changes in unwanted positions of the lever, as well as its premature wear by significant friction.

En remarque, un tel système d'indexation pourrait en variante être implémenté pour tout levier d'un élément de maintien de chaussure sur une planche de glisse, par exemple sur un simple levier d'ouverture ou de blocage d'une mâchoire de maintien d'une chaussure formant l'élément de maintien avant ou arrière d'une fixation de ski, ou un levier de déplacement pour le réglage de la longueur d'un élément de maintien, ou un levier de recul d'un élément de maintien arrière pour l'amener vers une position reculée dans une phase de montée lors de la pratique de la randonnée.As a remark, such an indexing system could alternatively be implemented for any lever of a shoe-holding element on a gliding board, for example on a simple lever for opening or locking a holding jaw. a shoe forming the front or rear holding member of a ski binding, or a movement lever for adjusting the length of a holding member, or a reversing lever of a rear holding member for bring it to a remote position in a climbing phase during the practice of hiking.

Ainsi, l'invention porte aussi sur un élément de maintien d'une chaussure sur une planche de glisse, comprenant un levier d'actionnement coopérant avec l'élément de maintien lors de sa rotation par l'intermédiaire d'un agencement élastique, permettant de former une indexation définissant plusieurs positions stables du levier. Notamment, l'agencement élastique comprend une vis, un écrou et une rondelle Belleville, ou plus généralement une rondelle ressort, agencés selon l'axe de rotation du levier et déformable élastiquement selon cet axe.Thus, the invention also relates to an element for holding a boot on a gliding board, comprising an actuating lever cooperating with the holding member during its rotation by means of an elastic arrangement, allowing to form an indexing defining several stable positions of the lever. In particular, the elastic arrangement comprises a screw, a nut and a Belleville washer, or more generally a spring washer, arranged along the axis of rotation of the lever and elastically deformable along this axis.

Préférentiellement, le levier, l'agrippe talon, l'embase, l'organe d'actionnement et la pédale du dispositif de freinage sont réalisés à partir d'un matériau plastique injecté. Toutefois d'autres matériaux pourraient être envisagés. Afin d'éviter que la rondelle Belleville 34 endommage la paroi de l'embase, une rondelle plate 36 peut être intercalée entre la rondelle Belleville et ladite paroi.Preferably, the lever, the heel grip, the base, the actuating member and the pedal of the braking device are made from an injected plastic material. However other materials could be considered. In order to prevent the Belleville washer 34 from damaging the wall of the base, a flat washer 36 may be interposed between the Belleville washer and said wall.

Grâce à l'invention, le dispositif de verrouillage du dispositif de freinage peut être facilement actionné avec un levier ergonomique. Le levier étant utile pour chausser ou déchausser le ski, une même manipulation permet à la fois de verrouiller ou déverrouiller le dispositif de freinage et d'actionner l'agrippe talon. L'invention ne se limite pas au mode de réalisation détaillé précédemment. Elle porte plus généralement sur tout levier de déchaussage permettant d'actionner un dispositif de verrouillage d'un dispositif de freinage. Le lien entre le levier et le dispositif de verrouillage peut être une liaison mécanique quelconque, par l'intermédiaire de tout élément d'actionnement. Avantageusement, le levier agit sur le dispositif de verrouillage par un appui direct sur le dispositif de verrouillage. Plus précisément, cet appui direct est réalisé sur l'organe de verrouillage lui-même du dispositif de verrouillage ou sur un élément qui lui est solidaire. En remarque, le levier permet l'actionnement du dispositif de verrouillage, de sa position de verrouillage vers sa position de déverrouillage et/ou inversement. Le levier participe aussi à une fonction complémentaire de maintien d'une ou des deux positions du dispositif de verrouillage. En remarque, dans le mode de réalisation décrit, l'agrippe talon participe en complément au maintien du dispositif de verrouillage dans la position déverrouillée, pour augmenter la fiabilité du dispositif. L'agrippe talon n'exerce aucun effet lors du changement de position du dispositif de verrouillage.Thanks to the invention, the locking device of the braking device can be easily operated with an ergonomic lever. The lever being useful for putting on or off the ski, the same manipulation makes it possible both to lock or unlock the braking device and to actuate the gripping bead. The invention is not limited to the embodiment detailed above. It more generally relates to any heaving lever for actuating a locking device of a braking device. The link between the lever and the locking device may be any mechanical connection, via any actuating element. Advantageously, the lever acts on the locking device by a direct support on the locking device. More specifically, this direct support is performed on the locking member itself of the locking device or on an element which is integral therewith. As a remark, the lever allows the actuation of the locking device, from its locking position to its unlocking position and / or vice versa. The lever also participates in a complementary function of maintaining one or both positions of the locking device. As a remark, in the embodiment described, the gripping heel participates in addition to maintaining the locking device in the unlocked position, to increase the reliability of the device. The heel grip has no effect when changing the position of the locking device.

Le levier passant au dessus de l'agrippe talon, il offre un bras de levier plus important que l'agrippe talon. L'effort nécessaire pour manipuler le levier est donc plus faible que pour manipuler l'agrippe talon. Enfin, le levier servant également de cale d'aide à la montée II n'est pas utile de prévoir un composant spécifique pour cette fonction. Un gain de poids peut donc être obtenu. Le dispositif de freinage est automatiquement activé lorsque le skieur déchausse le ski ce qui renforce sa sécurité car le ski ne peut pas être perdu lors de la manipulation du skiThe lever passing over the heel grip, it offers a greater leverage than the heel grip. The effort required to manipulate the lever is therefore lower than for handling the heel grip. Finally, the lever also serves as a support wedge to the rise II is not useful to provide a specific component for this function. Weight gain can therefore be obtained. The braking device is automatically activated when the skier takes off the ski which reinforces his safety because skiing can not be lost when handling the ski
