Definitions

  • the present invention relates to a device for retaining a boot on a gliding board as well as a gliding device comprising a gliding board, such as a cross-country ski or ski touring equipped with said retaining device.
  • a retaining device is sometimes referred to as a "stop", “front stop” or "attachment”.
  • a gliding device is a piece of equipment on which a person stands when using this device for the practice of a gliding sport, while being hooked by at least one of his shoes. on this machine.
  • the ski In the case of classic or alternative cross-country skiing, the ski is cambered and defines, under the boot, an area which, by default, is not in contact with the snow. This area constitutes a "wax room". In this zone, grip wax can be added to increase the grip of the ski on the snow in order to prevent the ski from rolling back, which makes it possible to exert effective thrust with the foot.
  • grip wax By modifying the longitudinal position of a device for retaining the boot on the ski, it is possible to adjust the contact zone between the ski and the snow according to the weight exerted by the skier, favoring sliding or hook. When turning, the skier has to lift one ski to bring it back towards the other ski.
  • the lifted ski is connected to the skier only by the front end of the boot and it is important that the ski is correctly balanced. If the ski leans forward or backward, it can touch the snow, which can slow the skier down or throw him off balance. Adjusting the length of a device for retaining a boot on the ski therefore makes it possible to adjust the balance of the ski in this raised configuration.
  • the document WO-A-2005/113081 describes notches on elastically deformable tabs of a retaining device for a cross-country ski boot, these notches being intended to cooperate with complementary notches provided on a ski.
  • the longitudinal immobilization of the retaining device along the ski depends on the rigidity of the tabs.
  • inadvertent attachment of one or the other of the tabs can separate the retaining device from the ski and lead to an undesired movement, forwards or backwards. To avoid this risk, it is then necessary to increase the stiffness of these tabs, which makes the longitudinal adjustment operation difficult without tools.
  • the document WO-A-2015/140258 offers a locking mechanism with a deformable tab provided with a notch. Locking is obtained by clipping or interference with a sliding plate. With this construction, there is a limited risk of acting on the deformable tongue. In these examples, the lock is exposed to external elements such as packed snow or ice which can accumulate in this area and disturb the locking mechanism and/or the actuation of the deformable tongue. In addition, the user may have doubts about the actuation of the lock after adjustment of the longitudinal position.

  • the article is characterized in that it comprises a holding means making it possible to hold the longitudinal stop element in a stable active position, independently of the position of the locking means.
  • the locking means when the user actuates the mechanism for holding his boot, the locking means systematically locks the longitudinal stop element.
  • the locking means is implemented. It is then no longer possible to deactivate the longitudinal arresting element, that is to say to move it relative to its active configuration, so that the longitudinal immobilization of the retaining device relative to the gliding device is durable and secure. With this securing, the user is assured that the adjustment of the longitudinal position of the retaining device of his shoe will remain unchanged as long as his shoe is in engagement with the binding. Furthermore, this construction makes it possible to design a longitudinal immobilization mechanism requiring little handling effort and therefore operable without tools.

Description

La présente invention concerne un dispositif de retenue d'une chaussure sur une planche de glisse ainsi qu'un engin de glisse comprenant une planche de glisse, tel qu'un ski de fond ou ski de randonnée équipé dudit dispositif de retenue. Un tel dispositif de retenue est parfois dénommé « butée », « butée avant » ou « fixation ».The present invention relates to a device for retaining a boot on a gliding board as well as a gliding device comprising a gliding board, such as a cross-country ski or ski touring equipped with said retaining device. Such a retaining device is sometimes referred to as a "stop", "front stop" or "attachment".

Au sens de la présente invention, un engin de glisse est un matériel sur lequel se tient une personne lors de l'utilisation de cet engin pour la pratique d'un sport de glisse, en étant accrochée par l'une au moins de ses chaussures sur cet engin.Within the meaning of the present invention, a gliding device is a piece of equipment on which a person stands when using this device for the practice of a gliding sport, while being hooked by at least one of his shoes. on this machine.

Dans le domaine des sports de glisse, plus particulièrement dans le domaine du ski de fond, il est avantageux de pouvoir régler la position longitudinale de la chaussure du skieur le long du ski.In the field of sliding sports, more particularly in the field of cross-country skiing, it is advantageous to be able to adjust the longitudinal position of the skier's boot along the ski.

Dans le cas du ski de fond classique ou alternatif, le ski est cambré et définit, sous la chaussure, une zone qui, par défaut, n'est pas en contact avec la neige. Cette zone constitue une « chambre de fart ». Dans cette zone, on peut ajouter du fart d'accroche de manière à augmenter l'adhérence du ski sur la neige afin d'empêcher le recul du ski, ce qui permet d'exercer une poussée efficace avec le pied. En modifiant la position longitudinale d'un dispositif de retenue de la chaussure sur le ski, il est possible d'ajuster la zone de contact entre le ski et la neige en fonction du poids exercé par le skieur, en privilégiant la glisse ou l'accroche. En virage, le skieur est amené à soulever un ski pour le ramener vers l'autre ski. Dans cette phase, le ski soulevé est relié au skieur uniquement par l'extrémité avant de la chaussure et il importe que le ski soit correctement équilibré. Si le ski penche vers l'avant ou vers l'arrière, il peut toucher la neige, ce qui peut ralentir le skieur ou le déséquilibrer. Le réglage en longueur d'un dispositif de retenue d'une chaussure sur le ski permet donc d'ajuster l'équilibre du ski dans cette configuration soulevée.In the case of classic or alternative cross-country skiing, the ski is cambered and defines, under the boot, an area which, by default, is not in contact with the snow. This area constitutes a "wax room". In this zone, grip wax can be added to increase the grip of the ski on the snow in order to prevent the ski from rolling back, which makes it possible to exert effective thrust with the foot. By modifying the longitudinal position of a device for retaining the boot on the ski, it is possible to adjust the contact zone between the ski and the snow according to the weight exerted by the skier, favoring sliding or hook. When turning, the skier has to lift one ski to bring it back towards the other ski. In this phase, the lifted ski is connected to the skier only by the front end of the boot and it is important that the ski is correctly balanced. If the ski leans forward or backward, it can touch the snow, which can slow the skier down or throw him off balance. Adjusting the length of a device for retaining a boot on the ski therefore makes it possible to adjust the balance of the ski in this raised configuration.

Dans le cas d'un ski de skating, on retrouve un problème similaire d'équilibre lorsque le ski est soulevé pour être amené vers l'autre ski dans les phases dites aériennes. En outre, lorsque la neige est collante, le skieur peut souhaiter un léger déséquilibre vers l'arrière de ses skis pour lever par défaut la spatule avant et limiter ainsi les risques de planter cette spatule dans la neige lors de la progression sur piste. Ces possibilités de réglage pour un ski de skating sont aussi obtenues grâce à un ajustement de la position longitudinale du dispositif de retenue d'une chaussure sur le ski.In the case of a skating ski, there is a similar problem of balance when the ski is lifted to be brought towards the other ski in the so-called aerial phases. In addition, when the snow is sticky, the skier may want a slight rearward imbalance of his skis in order to lift the front tip by default and thus limit the risks of planting this tip in the snow when progressing on the piste. These possibilities of adjustment for a skating ski are also obtained thanks to an adjustment of the longitudinal position of the device for retaining a boot on the ski.

Le réglage de la position longitudinale d'une fixation sur un ski de fond a été décrit dans plusieurs demandes de brevet. Cette fonction a d'ailleurs été intégrée dans certaines fixations du marché.Adjusting the longitudinal position of a binding on a cross-country ski has been described in several patent applications. This function has also been integrated into certain bindings on the market.

Par exemple, le document WO-A-2005/113081 décrit des crans sur des languettes élastiquement déformables d'un dispositif de retenue d'une chaussure de ski de fond, ces crans étant destinés à coopérer avec des crans complémentaires ménagés sur un ski. L'immobilisation longitudinale du dispositif de retenue le long du ski dépend de la rigidité des languettes. En outre, un accrochage intempestif de l'une ou l'autre des languettes peut désolidariser le dispositif de retenue du ski et amener à un déplacement non souhaité, vers l'avant ou vers l'arrière. Pour éviter ce risque, il faut alors augmenter la raideur de ces languettes ce qui rend difficile l'opération de réglage longitudinal sans outils.For example, the document WO-A-2005/113081 describes notches on elastically deformable tabs of a retaining device for a cross-country ski boot, these notches being intended to cooperate with complementary notches provided on a ski. The longitudinal immobilization of the retaining device along the ski depends on the rigidity of the tabs. In addition, inadvertent attachment of one or the other of the tabs can separate the retaining device from the ski and lead to an undesired movement, forwards or backwards. To avoid this risk, it is then necessary to increase the stiffness of these tabs, which makes the longitudinal adjustment operation difficult without tools.

Le document WO-A-2015/140258 propose un mécanisme de verrouillage d'une languette déformable munie d'un cran. Le verrouillage est obtenu par clipsage ou interférence avec une plaque coulissante. Avec cette construction, il y a un risque limité d'agir sur la languette déformable. Dans ces exemples, le verrou est exposé aux éléments extérieurs comme la neige tassée ou la glace qui peuvent s'accumuler dans cette zone et perturber le mécanisme de verrouillage et/ou l'actionnement de la languette déformable. De plus, l'utilisateur peut avoir un doute sur l'actionnement du verrou après réglage de la position longitudinale. Le document EP1839713 A1 divulgue un dispositif de retenue d'une chaussure sur une planche de glisse selon le préambule de la revendication 1.The document WO-A-2015/140258 offers a locking mechanism with a deformable tab provided with a notch. Locking is obtained by clipping or interference with a sliding plate. With this construction, there is a limited risk of acting on the deformable tongue. In these examples, the lock is exposed to external elements such as packed snow or ice which can accumulate in this area and disturb the locking mechanism and/or the actuation of the deformable tongue. In addition, the user may have doubts about the actuation of the lock after adjustment of the longitudinal position. The document EP1839713 A1 discloses a device for retaining a shoe on a gliding board according to the preamble of claim 1.

Le but de l'invention est de proposer un dispositif de retenue d'une chaussure sur une planche de glisse améliorée.The object of the invention is to provide a device for retaining a boot on an improved gliding board.

Un but est notamment de proposer un mécanisme de réglage de la position longitudinale d'un dispositif de retenue sur une planche de glisse fiable.One aim is in particular to provide a mechanism for adjusting the longitudinal position of a retaining device on a reliable gliding board.

Un autre but est de proposer un mécanisme de réglage de la position longitudinale d'un dispositif de retenue sur une planche de glisse facile à utiliser, notamment sans outils.Another object is to provide a mechanism for adjusting the longitudinal position of a retaining device on a gliding board that is easy to use, in particular without tools.

Un autre but est de proposer un mécanisme de réglage de la position longitudinale d'un dispositif de retenue sur une planche de glisse pour lequel l'utilisateur est sûr d'avoir une position longitudinale verrouillée en utilisation.Another object is to propose a mechanism for adjusting the longitudinal position of a retaining device on a gliding board for which the user is sure of having a locked longitudinal position in use.

L'invention propose un dispositif de retenue d'une chaussure sur une planche de glisse, le dispositif de retenue comprenant :

  • un mécanisme de maintien en position d'un élément d'accrochage appartenant à la chaussure, le mécanisme de maintien comprenant une mâchoire mobile entre une position d'enclenchement pour laquelle la mâchoire mobile est apte à coopérer avec l'élément d'accrochage de sorte à permettre la solidarisation de l'élément d'accrochage avec le dispositif de retenue tout en permettant la rotation de la chaussure autour d'un axe transversal au dispositif de retenue, et une position de libération pour laquelle la mâchoire mobile est dans une configuration permettant la désolidarisation de l'élément d'accrochage avec le dispositif de retenue, et un organe d'actionnement commandant un déplacement de la mâchoire mobile pour la faire basculer d'une position d'enclenchement vers une position de libération,
  • un élément d'arrêt longitudinal mobile entre une position active pour laquelle l'élément d'arrêt longitudinal est apte à coopérer avec des indexations complémentaires solidaires de la planche de glisse pour immobiliser le dispositif de retenue le long de la planche de glisse dans l'une de plusieurs positions prédéterminées, et une position inactive pour laquelle l'élément d'arrêt longitudinal ne coopère pas avec les indexations complémentaires,
  • un moyen de verrouillage mobile entre une position de verrouillage pour laquelle le moyen de verrouillage est apte à coopérer avec l'élément d'arrêt de sorte à le maintenir dans sa configuration active et une position de déverrouillage pour laquelle le moyen de verrouillage mobile est dans une configuration permettant le basculement de l'élément d'arrêt de sa position active vers sa position inactive.
  • le moyen de verrouillage étant cinématiquement lié à la mâchoire mobile de sorte que, lorsque le moyen de verrouillage est dans sa position de verrouillage, la mâchoire mobile est systématiquement dans sa position d'enclenchement.
The invention proposes a device for retaining a boot on a gliding board, the retention device comprising:
  • a mechanism for holding in position an attachment element belonging to the shoe, the holding mechanism comprising a movable jaw between an engagement position for which the movable jaw is capable of cooperating with the attachment element so to allow the attachment of the attachment element to the retaining device while allowing rotation of the shoe about an axis transverse to the retaining device, and a release position for which the movable jaw is in a configuration allowing the separation of the attachment element with the retaining device, and an actuating member controlling a movement of the movable jaw to make it switch from an engagement position to a release position,
  • a movable longitudinal stop element between an active position for which the longitudinal stop element is capable of cooperating with complementary indexings integral with the gliding board to immobilize the retaining device along the gliding board in the one of several predetermined positions, and an inactive position for which the longitudinal stop element does not cooperate with the complementary indexings,
  • a locking means movable between a locking position for which the locking means is capable of cooperating with the stop element so as to maintain it in its active configuration and an unlocking position for which the movable locking means is in a configuration allowing the tilting of the stop element from its active position to its inactive position.
  • the locking means being kinematically linked to the movable jaw so that, when the locking means is in its locking position, the movable jaw is systematically in its engagement position.

L'article est caractérisé en ce qu'il comprend un moyen de maintien permettant de maintenir l'élément d'arrêt longitudinal dans une position active stable, indépendamment de la position du moyen de verrouillage.The article is characterized in that it comprises a holding means making it possible to hold the longitudinal stop element in a stable active position, independently of the position of the locking means.

Grâce à l'invention, lorsque l'utilisateur actionne le mécanisme de maintien de sa chaussure, le moyen de verrouillage verrouille systématiquement l'élément d'arrêt longitudinal. Le moyen de verrouillage est mis en oeuvre. Il n'est alors plus possible de désactiver l'élément d'arrêt longitudinal, c'est-à-dire de le déplacer par rapport à sa configuration active, de sorte que l'immobilisation longitudinale du dispositif de retenue par rapport à l'engin de glisse est pérenne et sécurisée. Avec cette sécurisation, l'utilisateur est assuré que le réglage de la position longitudinale du dispositif de retenue de sa chaussure restera inchangé tant que sa chaussure sera en prise avec la fixation. Par ailleurs, cette construction permet de concevoir un mécanisme d'immobilisation longitudinale demandant peu d'effort de manipulation et donc actionnable sans outils.By virtue of the invention, when the user actuates the mechanism for holding his boot, the locking means systematically locks the longitudinal stop element. The locking means is implemented. It is then no longer possible to deactivate the longitudinal arresting element, that is to say to move it relative to its active configuration, so that the longitudinal immobilization of the retaining device relative to the gliding device is durable and secure. With this securing, the user is assured that the adjustment of the longitudinal position of the retaining device of his shoe will remain unchanged as long as his shoe is in engagement with the binding. Furthermore, this construction makes it possible to design a longitudinal immobilization mechanism requiring little handling effort and therefore operable without tools.

L'invention concerne également un engin de glisse comprenant une planche de glisse et un dispositif de retenue.The invention also relates to a gliding device comprising a gliding board and a retaining device.

Selon un mode de réalisation de l'invention, l'engin de glisse comprend une interface disposée entre la planche de glisse et le dispositif de retenue, l'interface portant les indexations complémentaires.

Other characteristics and advantages of the invention will be better understood with the aid of the description which will follow, with regard to the appended drawings illustrating, according to non-limiting embodiments, how the invention can be carried out, and in which :
  • there figure 1 is a perspective view from the front of part of a gliding device equipped with a retaining device in accordance with the invention, in a first configuration of use,

Dans la suite de la description, il sera fait usage de termes tels que « horizontal », « vertical », « transversal », « supérieur », « inférieur », « latéral », « haut », « bas », « droite », « gauche », « avant », « arrière », « devant », « derrière ». Ces termes doivent être interprétés de façon relative en relation avec la position normale que l'engin de glisse occupe quand l'utilisateur l'utilise sur une piste sensiblement plane.In the rest of the description, use will be made of terms such as "horizontal", "vertical", "transverse", "upper", "lower", "lateral", "top", "bottom", "right" , "left", "front", "back", "front", "back". These terms should be interpreted relatively in relation to the normal position that the gliding device occupies when the user uses it on a substantially flat track.

On utilisera également un repère dont la direction avant/arrière correspond à l'axe X, la direction transversale ou droite/gauche correspond à l'axe Y et la direction verticale ou haut/bas correspond à l'axe Z.We will also use a marker whose front/rear direction corresponds to the X axis, the transverse or right/left direction corresponds to the Y axis and the vertical or up/down direction corresponds to the Z axis.

L'invention concerne un ensemble de glisse 4 comprenant une planche de glisse 3 s'étendant selon un axe longitudinal X3, une interface 2 fixée sur la face supérieure 32 du ski 3 opposée à sa surface de glisse 31 et un dispositif de retenue 1 d'une chaussure 5, ou fixation, monté sur l'interface avec possibilité de coulissement par rapport au ski 3, le long de son axe longitudinal X.The invention relates to a gliding assembly 4 comprising a gliding board 3 extending along a longitudinal axis X3, an interface 2 fixed to the upper face 32 of the ski 3 opposite its gliding surface 31 and a retaining device 1 d a boot 5, or binding, mounted on the interface with the possibility of sliding relative to the ski 3, along its longitudinal axis X.

L'interface 2 est immobilisée sur le ski 3 par tout moyen approprié. Cela peut être par collage ou par des vis. L'interface 2 présente une face supérieure 20 et comprend une partie centrale 21 et deux ailes latérales 22 qui s'étendent de part et d'autre de la partie centrale 21. Dans la partie arrière de l'interface, chaque aile comprend un ergot 221 faisant saillie de la face supérieure 20. L'ergot 221 est ménagé sur une poutre déformable 222 dimensionnée de sorte que l'ergot puisse s'escamoter sous le niveau de la face supérieure 20 lorsqu'on exerce un effort vertical Z sur l'ergot. Le bord extérieur de chaque aile latérale 22 forme un rail latéral s'étendant selon une direction parallèle à l'axe longitudinal X2 de l'interface. L'interface 2 est fixée sur le ski de sorte que l'axe longitudinal X3 du ski et l'axe longitudinal X2 de l'interface soient parallèles. Dans sa partie centrale 21, l'interface 2 comprend des rainures de guidage 211 et un logement 212 destiné à recevoir un insert 23, monté amovible sur l'interface. L'insert 23 comprend des rainures de guidage longitudinal 231 ainsi qu'une série de crantages 232 délimitant un bord d'une rainure longitudinale centrale 233. Comme nous le verrons par la suite, la série de crantages 232 forme des indexations complémentaires destinées à coopérer avec des crans 1631 d'un élément d'arrêt longitudinal 16 de sorte à pouvoir immobiliser le dispositif de retenue le long de la planche de glisse, dans l'une de plusieurs positions prédéterminées. Lorsque l'insert est assemblé sur la partie centrale de l'embase, chaque crantage 232 est orienté selon une direction Y transversale à l'embase et débouche dans la rainure centrale 233 et tous les crantages sont alignés selon une direction longitudinale X parallèle à l'axe longitudinal X2 de l'interface. A l'usage, les crantages 232 sont fortement sollicités du fait que ce sont eux qui maintiennent le dispositif de retenue en position, selon la direction longitudinale X parallèle à l'axe longitudinal X2 de l'interface. De plus, le dimensionnement de ces crantages doit pouvoir se loger dans un faible encombrement, préférablement dans l'épaisseur de l'interface. Ces contraintes de conception demandent l'utilisation d'un matériau adapté pour résister aux sollicitations. La construction proposée consistant à rapporter un insert amovible présente plusieurs avantages. Cela permet, d'une part, de changer la pièce si le crantage est abimé et, d'autre part, l'utilisation de matériau plus rigide localement, là où cela est nécessaire, sans pénaliser le poids de l'interface et donc du ski. Par exemple l'insert peut être métallique alors que le reste de l'interface est en plastique. L'insert peut être monté amovible sur l'interface par tout moyen approprié. Ce peut être par clipsage ou à l'aide d'une vis. Cette solution est transposable à tout système de réglage de la position longitudinale d'un dispositif de retenue par rapport à un ski utilisant des moyens d'indexation et n'est donc pas limité au mode de réalisation illustré ici. En variante, la série de crantages 232 est directement réalisée dans la partie centrale 21 et non sur un insert rapporté.The interface 2 is immobilized on the ski 3 by any appropriate means. This can be by gluing or by screws. The interface 2 has an upper face 20 and comprises a central part 21 and two lateral wings 22 which extend on either side of the central part 21. In the rear part of the interface, each wing comprises a lug 221 protruding from the upper face 20. The lug 221 is provided on a deformable beam 222 dimensioned so that the lug can retract below the level of the upper face 20 when a vertical force Z is exerted on the ergot. The outer edge of each side wing 22 forms a side rail extending in a direction parallel to the longitudinal axis X2 of the interface. The interface 2 is fixed on the ski so that the longitudinal axis X3 of the ski and the longitudinal axis X2 of the interface are parallel. In its central part 21, the interface 2 comprises guide grooves 211 and a housing 212 intended to receive an insert 23, removably mounted on the interface. The insert 23 comprises longitudinal guide grooves 231 as well as a series of notches 232 delimiting an edge of a central longitudinal groove 233. As we will see later, the series of notches 232 form complementary indexings intended to cooperate with notches 1631 of a longitudinal stop element 16 so as to be able to immobilize the retaining device along the gliding board, in one of several predetermined positions. When the insert is assembled on the central part of the base, each notch 232 is oriented in a direction Y transverse to the base and opens into the central groove 233 and all the notches are aligned in a longitudinal direction X parallel to the longitudinal axis X2 of the interface. In use, the notches 232 are heavily stressed because they are the ones that hold the retaining device in position, along the longitudinal direction X parallel to the longitudinal axis X2 of the interface. In addition, the dimensioning of these notches must be able to be housed in a small space, preferably in the thickness of the interface. These design constraints require the use of a suitable material to withstand the stresses. The proposed construction consisting in adding a removable insert has several advantages. This allows, on the one hand, to change the part if the cogging is damaged and, on the other hand, the use of more rigid material locally, where necessary, without penalizing the weight of the interface and therefore of the ski. For example, the insert may be metallic while the rest of the interface is made of plastic. The insert can be removably mounted on the interface by any appropriate means. This can be by clipping or using a screw. This solution can be transposed to any system for adjusting the longitudinal position of a retaining device relative to a ski using indexing means and is therefore not limited to the embodiment illustrated here. Alternatively, the series of notches 232 is made directly in the central part 21 and not on an added insert.

Le dispositif de retenue 1 comprend une embase 11, un mécanisme 17 de maintien en position d'un élément d'accrochage 51 appartenant à la chaussure 5, un élément d'arrêt longitudinal 16, un moyen de verrouillage 18 de l'élément d'arrêt longitudinal et un moyen de rappel 19 permettant de rapprocher le talon de la chaussure vers le ski.The retaining device 1 comprises a base 11, a mechanism 17 for holding in position an attachment element 51 belonging to the boot 5, a longitudinal stop element 16, a locking means 18 of the longitudinal stop and a return means 19 making it possible to bring the heel of the boot closer to the ski.

L'embase 11 est conçue pour s'assembler à l'interface 2. Elle s'étend selon un axe longitudinal X1 sensiblement parallèle à l'axe longitudinal X2 de l'interface lorsque l'embase est montée sur l'interface. L'embase comprend une face inférieure 111 destinée à venir contre la face supérieure 20 de l'interface 2. La face inférieure 111 est délimitée latéralement par deux rebords formant chacun une rainure latérale interne 112 orientée selon une direction longitudinale parallèle à l'axe longitudinal X1 de l'embase. Chaque rainure latérale interne 112 est destinée à coopérer respectivement avec un rail formé par une des ailes latérales 22 de sorte à guider en translation l'embase par rapport à l'interface, selon une direction longitudinale X. Cette coopération permet également le maintien de la face inférieure de l'embase contre la face supérieure de l'interface en empêchant leur écartement selon une direction Z, normale à la face supérieure de l'interface. Cette coopération définit ainsi une liaison de type glissière entre l'embase et l'interface assurant le coulissement du dispositif de retenue par rapport au ski. Pour améliorer le guidage en translation, l'embase comprend également des nervures de guidage 113 faisant saillies de la face inférieure 111. Chaque nervure de guidage est conçue pour coopérer avec une rainure de guidage complémentaire 211 ménagée sur la face supérieure 20 de l'interface 2. Dans sa partie arrière, la face inférieure 111 comprend, de chaque côté, une rangée d'orifices 114 alignées selon une direction X parallèle à l'axe longitudinal X1 de l'embase. Chaque orifice 114 est conçu pour recevoir un ergot 221 de l'interface 2 pour une position particulière de l'embase. Ainsi, lorsqu'un ergot 221 coopère avec un orifice 114 d'une rangée, l'embase 111 est positionnée à une position indexée déterminée. Cette coopération assure l'indexation de la position de l'embase par rapport à l'interface. Cependant, le dimensionnement des ergots et orifices n'est pas suffisant pour permettre le maintien de la position longitudinale de l'embase par rapport à l'interface. Nous verrons par la suite que cette fonction est assurée par un autre dispositif.The base 11 is designed to be assembled on the interface 2. It extends along a longitudinal axis X1 substantially parallel to the longitudinal axis X2 of the interface when the base is mounted on the interface. The base comprises a lower face 111 intended to come against the upper face 20 of the interface 2. The lower face 111 is delimited laterally by two flanges each forming an internal lateral groove 112 oriented in a longitudinal direction parallel to the longitudinal axis X1 of the base. Each internal lateral groove 112 is intended to cooperate respectively with a rail formed by one of the lateral flanges 22 so as to guide the base in translation relative to the interface, in a longitudinal direction X. This cooperation also allows the maintenance of the lower face of the base against the upper face of the interface by preventing their separation in a direction Z, normal to the upper face of the interface. This cooperation thus defines a slide-type connection between the base and the interface ensuring the sliding of the retaining device with respect to the ski. To improve guidance in translation, the base also comprises guide ribs 113 projecting from the lower face 111. Each guide rib is designed to cooperate with a complementary guide groove 211 formed on the upper face 20 of the interface. 2. In his game rear, the lower face 111 comprises, on each side, a row of orifices 114 aligned in a direction X parallel to the longitudinal axis X1 of the base. Each orifice 114 is designed to receive a pin 221 of the interface 2 for a particular position of the base. Thus, when a lug 221 cooperates with an orifice 114 of a row, the base 111 is positioned at a determined indexed position. This cooperation ensures the indexing of the position of the base relative to the interface. However, the dimensioning of the lugs and orifices is not sufficient to enable the longitudinal position of the base to be maintained with respect to the interface. We will see later that this function is provided by another device.

Dans sa partie arrière supérieure, l'embase 11 comprend au moins une arête de guidage 115 apte à coopérer avec au moins une rainure 53 ménagée sur la semelle 52 de la chaussure 5 de sorte à limiter le déplacement transversal de la chaussure lorsque la semelle se rapproche de la planche de glisse 3.In its upper rear part, the base 11 comprises at least one guide edge 115 capable of cooperating with at least one groove 53 provided on the sole 52 of the shoe 5 so as to limit the transverse displacement of the shoe when the sole closer to the gliding board 3.

De manière classique, l'embase 11 porte, dans sa partie supérieure, le mécanisme 17 de maintien en position d'un élément d'accrochage 51 appartenant à la chaussure 5. Dans le mode de réalisation de l'invention illustré, l'élément d'accrochage 51 est un arbre transversal intégré dans un évidement de l'avant de la semelle 52 de la chaussure 5. En pratique, la chaussure 5 peut être conforme à l'enseignement technique des demandes EP-A-0 913 102 et/ou EP-A-0 913 103 auxquelles on peut se référer pour plus de détails. Pour assurer la solidarisation de la chaussure avec le dispositif de retenue, le mécanisme de maintien 17 comprend une mâchoire fixe 12, une mâchoire mobile 13, un organe d'actionnement 14 et des biellettes 15. Le fonctionnement ne sera pas décrit en détail car il est analogue à celui de la fixation décrite dans le document FR-A-2638974 .Conventionally, the base 11 carries, in its upper part, the mechanism 17 for holding in position an attachment element 51 belonging to the boot 5. In the illustrated embodiment of the invention, the element attachment 51 is a transverse shaft integrated in a recess in the front of the sole 52 of the shoe 5. In practice, the shoe 5 can conform to the technical teaching of the demands EP-A-0 913 102 and or EP-A-0 913 103 which can be referred to for more details. To ensure the attachment of the shoe to the retaining device, the holding mechanism 17 comprises a fixed jaw 12, a movable jaw 13, an actuating member 14 and rods 15. The operation will not be described in detail because it is similar to that of the binding described in the document FR-A-2638974 .

La mâchoire mobile 13 peut se déplacer entre une position d'enclenchement, représentée à la figure 3, pour laquelle la mâchoire mobile est apte à coopérer avec l'élément d'accrochage 51 de sorte à permettre la solidarisation de l'élément d'accrochage avec le dispositif de retenue tout en permettant la rotation de la chaussure autour d'un axe transversal Y1 au dispositif de retenue, et une position de libération pour laquelle la mâchoire mobile est dans une configuration, représentée aux figures 1, 2 et 6, permettant la désolidarisation de l'élément d'accrochage avec le dispositif de retenue.The movable jaw 13 can move between an engagement position, shown in picture 3 , for which the movable jaw is capable of cooperating with the attachment element 51 so as to allow the fastening of the attachment element with the retaining device while allowing the boot to rotate about a transverse axis Y1 to the retaining device, and a release position for which the movable jaw is in a configuration, shown in figure 1 , 2 And 6 , allowing the separation of the attachment element with the retaining device.

Dans cet exemple, lorsque la mâchoire mobile 13 se déplace de sa position de libération vers sa position d'enclenchement, la mâchoire mobile 13 se rapproche de la mâchoire fixe 12 de manière à former sensiblement, avec la mâchoire fixe, un cylindre à l'intérieur pouvant accueillir l'élément d'accrochage 51 de sorte que celui-ci puisse librement pivoter autour de l'axe Y1 du cylindre formé. Ainsi, la mâchoire fixe 12 est disposée de sorte que l'élément d'accrochage 51 est positionné entre la mâchoire mobile 13 et la mâchoire fixe 12 lorsque la chaussure 5 est en prise avec le dispositif de retenue 1. A l'inverse, lorsque la mâchoire mobile 13 se déplace de sa position d'enclenchement vers sa position de libération, la mâchoire mobile 13 s'écarte de la mâchoire fixe 12 de manière à générer une ouverture entre les deux mâchoires à travers laquelle peut passer l'élément d'accrochage 51. Dans cet exemple, la mâchoire mobile 13 est positionnée devant la mâchoire fixe 12 sur l'embase 11.In this example, when the movable jaw 13 moves from its release position to its engagement position, the movable jaw 13 approaches the fixed jaw 12 so as to substantially form, with the fixed jaw, a cylinder at the interior that can accommodate the attachment element 51 so that the latter can freely pivot around the axis Y1 of the cylinder formed. Thus, the fixed jaw 12 is arranged so that the hooking element 51 is positioned between the movable jaw 13 and the fixed jaw 12 when the boot 5 is engaged with the retaining device 1. Conversely, when there mobile jaw 13 moves from its engagement position to its release position, the mobile jaw 13 moves away from the fixed jaw 12 so as to generate an opening between the two jaws through which the hooking element can pass 51. In this example, the movable jaw 13 is positioned in front of the fixed jaw 12 on the base 11.

Pour faire basculer la mâchoire mobile de sa position d'enclenchement vers sa position de libération, ou inversement, le mécanisme de maintien 17 comprend un dispositif de commande actionné par un organe d'actionnement 14 manipulable par l'utilisateur. Dans l'exemple illustré, le dispositif de commande est similaire à celui décrit dans le document FR-A-2638974 . Il comprend un organe d'actionnement 14 sous la forme d'un capot monté pivotant sur le corps de la mâchoire mobile 13 autour d'un axe transversal Y14. Par ailleurs, chaque bord latéral du capot 14 est relié à une partie avant de l'embase 11 par une biellette 15. Une première extrémité de la biellette est montée rotative sur la partie avant de l'embase autour d'un axe transversal Y15a. Une deuxième extrémité de la biellette est montée rotative sur un bord latéral de l'organe d'actionnement autour d'un axe transversal Y15b parallèle à l'axe de pivotement Y14 de l'organe d'actionnement.To tilt the movable jaw from its engagement position to its release position, or vice versa, the holding mechanism 17 comprises a control device actuated by an actuating member 14 that can be manipulated by the user. In the example shown, the control device is similar to that described in the document FR-A-2638974 . It comprises an actuating member 14 in the form of a cover pivotally mounted on the body of the movable jaw 13 about a transverse axis Y14. Furthermore, each side edge of the cover 14 is connected to a front part of the base 11 by a link 15. A first end of the link is rotatably mounted on the front part of the base around a transverse axis Y15a. A second end of the connecting rod is rotatably mounted on a lateral edge of the actuator member around a transverse axis Y15b parallel to the pivot axis Y14 of the actuator member.

En abaissant l'organe d'actionnement 14, l'utilisateur entraîne le déplacement de la mâchoire mobile 13 vers sa position d'enclenchement. A l'inverse, en le soulevant, l'organe d'actionnement commande le déplacement de la mâchoire mobile pour la faire basculer de la position d'enclenchement vers la position de libération. Dans cet exemple, lorsqu'il est complètement abaissé, l'organe d'actionnement 14 est conçu pour venir en appui contre une face supérieure avant 116 de l'embase 11. Dans cette configuration, la mâchoire mobile est dans sa position d'enclenchement.By lowering the actuating member 14, the user causes the moving jaw 13 to move towards its engagement position. Conversely, by lifting it, the actuating member controls the movement of the movable jaw to make it switch from the engagement position to the release position. In this example, when it is completely lowered, the actuating member 14 is designed to bear against an upper front face 116 of the base 11. In this configuration, the mobile jaw is in its engagement position .

Dans cet exemple, le dispositif de commande est conçu pour assurer un verrouillage de la mâchoire mobile en position d'enclenchement. Ainsi, lorsque l'organe d'actionnement est complètement relevé, la mâchoire mobile est dans sa position de libération. En abaissant l'organe d'actionnement d'un angle déterminé, la mâchoire mobile est amenée à sa position d'enclenchement. Puis, en poursuivant la rotation de l'organe d'actionnement jusqu'à ce qu'il vienne en appui contre une face supérieure avant 116 de l'embase 11, la mâchoire mobile est verrouillée dans sa position d'enclenchement et ne peut plus bouger longitudinalement, selon la direction X, sans une action sur l'organe d'actionnement.In this example, the control device is designed to ensure locking of the mobile jaw in the engagement position. Thus, when the actuating member is fully raised, the movable jaw is in its release position. By lowering the actuating member by a determined angle, the movable jaw is brought to its engagement position. Then, by continuing the rotation of the actuating member until it bears against an upper front face 116 of the base 11, the movable jaw is locked in its engagement position and can no longer move longitudinally, in direction X, without action on the actuating member.

L'organe d'actionnement 14 définit un capot intégrant un évidement inférieur 141 prévu pour former avec la face supérieure avant 116 de l'embase 11 et une partie du corps de la mâchoire mobile 13, un volume sensiblement fermé lorsque l'organe d'actionnement 14 repose sur la face supérieure avant 116 de l'embase 11. Ainsi, dans cette configuration, l'organe d'actionnement 14 permet de protéger les éléments logés dans cette cavité des intempéries extérieures comme la neige ou la glace. Les biellettes 15 sont agencées pour venir se loger dans cette cavité lorsque l'organe d'actionnement 14 est abaissé, c'est-à-dire, quand le dispositif de retenue est enclenché.The actuating member 14 defines a cover incorporating a lower recess 141 provided to form with the upper front face 116 of the base 11 and a part of the body of the movable jaw 13, a substantially closed volume when the actuation 14 rests on the upper front face 116 of the base 11. Thus, in this configuration, the actuation member 14 makes it possible to protect the elements housed in this cavity from external bad weather such as snow or ice. The connecting rods 15 are arranged to come to lodge in this cavity when the actuating member 14 is lowered, that is to say, when the retaining device is engaged.

Selon un mode de réalisation de l'invention, le moyen de rappel 19 permettant de rapprocher le talon de la chaussure vers le ski est un tampon élastique porté par le corps de la mâchoire mobile 13. Le tampon élastique 19 est conçu pour venir en appui contre une face avant de la semelle lorsque l'utilisateur soulève son talon. Ce type de moyen de rappel est illustré dans le document FR-A-2638974 .According to one embodiment of the invention, the return means 19 making it possible to bring the heel of the boot closer to the ski is an elastic buffer carried by the body of the mobile jaw 13. The elastic buffer 19 is designed to come into contact against a front face of the sole when the user raises his heel. This type of recall means is illustrated in the document FR-A-2638974 .

Selon l'invention, le dispositif de retenue comprend un élément d'arrêt longitudinal 16 mobile entre une position active, représentée aux figures 2, 6 et 8, pour laquelle l'élément d'arrêt longitudinal est apte à coopérer avec des indexations complémentaires 232 solidaires de la planche de glisse afin d'immobiliser le dispositif de retenue le long de la planche de glisse dans l'une de plusieurs positions prédéterminées, et une position inactive, représentée aux figures 1 et 7, pour laquelle l'élément d'arrêt longitudinal ne coopère pas avec les indexations complémentaires. Dans cet exemple, l'élément d'arrêt longitudinal 16 est un poussoir inséré dans un logement traversant 117 de la partie avant de l'embase 11 de sorte qu'une partie supérieure de l'élément d'arrêt fasse saillie de la face supérieure 116 de l'embase 11 et qu'une partie inférieure de l'élément d'arrêt fasse saillie de la face inférieure 111 de l'embase 11. Par ailleurs, le logement est également conçu pour permettre le coulissement du poussoir 16 selon une direction Y16 transversale à l'embase entre ses positions active et inactive. Ainsi, l'élément d'arrêt longitudinal est mobile selon une direction transversale au dispositif de retenue.According to the invention, the retaining device comprises a longitudinal stop element 16 movable between an active position, shown in figure 2 , 6 And 8 , for which the longitudinal stop element is capable of cooperating with complementary indexings 232 integral with the gliding board in order to immobilize the retaining device along the gliding board in one of several predetermined positions, and an inactive position, shown in figure 1 And 7 , for which the longitudinal stop element does not cooperate with the complementary indexings. In this example, the longitudinal stop element 16 is a pusher inserted in a through housing 117 of the front part of the base 11 so that an upper part of the stop element protrudes from the upper face 116 of the base 11 and that a lower part of the stop element protrudes from the lower face 111 of the base 11. Furthermore, the housing is also designed to allow the sliding of the pusher 16 in one direction Y16 transverse to the base between its active and inactive positions. Thus, the longitudinal stop element is movable in a direction transverse to the retaining device.

Dans sa partie supérieure, l'élément d'arrêt 16 comprend, d'un côté, une première extension transversale 161 délimitée latéralement par une première surface d'actionnement 1611 inclinée par rapport à un plan vertical, avantageusement, d'un angle supérieur à 25° et inférieur à 50°. Du côté opposé, l'élément d'arrêt comprend une deuxième extension transversale 162 délimitée latéralement par une deuxième surface d'actionnement 1621 inclinée par rapport à un plan vertical, avantageusement, d'un angle supérieur à 25° et inférieur à 50°. Ces surfaces d'actionnement sont agencées de sorte que lorsque l'utilisateur appuie sur la première surface d'actionnement 1611, il entraîne la translation de l'élément d'arrêt 16 selon une direction transversale Y16 pour le faire basculer de sa position inactive vers sa position active. A l'inverse, lorsque l'utilisateur appuie sur la deuxième surface d'actionnement 1621, il entraîne la translation de l'élément d'arrêt 16 selon une direction transversale Y16, dans l'autre sens, pour le faire basculer de sa position active vers sa position inactive. Chaque extension transversale 161, 162 présente une surface inférieure 1612, 1622 destinée à se positionner contre la face supérieure 116 de l'interface 11.In its upper part, the stop element 16 comprises, on one side, a first transverse extension 161 delimited laterally by a first actuation surface 1611 inclined with respect to a vertical plane, advantageously, by an angle greater than 25° and less than 50°. On the opposite side, the stop element comprises a second transverse extension 162 delimited laterally by a second actuation surface 1621 inclined relative to a vertical plane, advantageously by an angle greater than 25° and less than 50°. These actuating surfaces are arranged so that when the user presses on the first actuating surface 1611, he causes the translation of the stop element 16 in a transverse direction Y16 to make it switch from its inactive position to its active position. Conversely, when the user presses on the second actuating surface 1621, he causes the translation of the stop element 16 in a transverse direction Y16, in the other direction, to make it switch from its position active to its inactive position. Each transverse extension 161, 162 has a lower surface 1612, 1622 intended to be positioned against the upper face 116 of the interface 11.

Chaque extension transversale 161, 162 comprend également un élément de positionnement 1613, 1623 ménagé respectivement sur la surface inférieure 1612, 1622 d'une extension transversale 161, 162. Pour certaines positions transversales de l'élément d'arrêt 16, un élément de positionnement 1613, 1623 est apte à coopérer avec un élément de positionnement complémentaire 118 ménagé sur la surface supérieure 116 de l'interface 11 de sorte à maintenir l'élément d'arrêt 16 dans cette position stable. Ainsi, lorsque l'élément d'arrêt 16 dans sa position inactive, l'élément de positionnement 1613 de la première extension transversale 161 coopère avec un premier élément de positionnement complémentaire 118 de l'embase 11. Par ailleurs, lorsque l'élément d'arrêt 16 dans sa position active, l'élément de positionnement 1623 de la deuxième extension transversale 162 coopère avec un deuxième élément de positionnement complémentaire 118 de l'embase 11. L'élément d'arrêt longitudinal comprend un élément de positionnement 1613, 1623 apte à coopérer avec un élément de positionnement complémentaire 118 du dispositif de retenue de sorte à maintenir l'élément d'arrêt longitudinal 16 dans une position stable parmi les positions active ou inactive. Dans cet exemple, un élément de positionnement 1613, 1623 est une bosse faisant saillie de la surface inférieure 1612, 1622 d'une extension transversale 161, 162. Dans ce cas, un élément de positionnement complémentaire 118 est un creux ménagé sur la surface supérieure 116 de l'interface 11.Each transverse extension 161, 162 also includes a positioning element 1613, 1623 formed respectively on the lower surface 1612, 1622 a transverse extension 161, 162. For certain transverse positions of the stop element 16, a positioning element 1613, 1623 is capable of cooperating with a complementary positioning element 118 provided on the upper surface 116 of the interface 11 so as to maintain the stop element 16 in this stable position. Thus, when the stop element 16 in its inactive position, the positioning element 1613 of the first transverse extension 161 cooperates with a first complementary positioning element 118 of the base 11. Moreover, when the element of stop 16 in its active position, the positioning element 1623 of the second transverse extension 162 cooperates with a second complementary positioning element 118 of the base 11. The longitudinal stop element comprises a positioning element 1613, 1623 capable of cooperating with a complementary positioning element 118 of the retaining device so as to maintain the longitudinal stop element 16 in a stable position among the active or inactive positions. In this example, a positioning element 1613, 1623 is a bump protruding from the lower surface 1612, 1622 of a transverse extension 161, 162. In this case, a complementary positioning element 118 is a depression formed on the upper surface 116 of interface 11.

Dans sa partie supérieure, l'élément d'arrêt 16 comprend une extension inférieure 163 faisant saillie de la face inférieure 111 de l'embase 11 lorsque l'élément d'arrêt est assemblé sur l'embase. Cette extension inférieure 163 comprend deux crans 1631 orientés selon une direction Y, transversale à l'embase lorsque l'élément d'arrêt est assemblé sur l'embase. Les crans 1631 sont dimensionnés et agencés de sorte qu'ils puissent coopérer avec les indexations complémentaires 232 de l'embase lorsque l'élément d'arrêt est dans sa position active et de sorte qu'ils ne coopèrent plus avec les indexations complémentaires 232 de l'embase lorsque l'élément d'arrêt est dans sa position inactive. Dans ce dernier cas, l'extension inférieure 163 se positionne dans la rainure longitudinale centrale 233. Ainsi, lorsqu'il est dans sa position inactive, l'élément d'arrêt 16 peut se déplacer le long de l'interface 11, dans la rainure longitudinale centrale 233. Par contre, lorsqu'il est dans sa position active, l'élément d'arrêt 16 est solidaire de l'interface 11 selon la direction longitudinale X du fait que les crans 1631 sont en prise avec les indexations complémentaires 232 de l'embase. L'élément d'arrêt 16 permet donc l'immobilisation du dispositif de retenue le long de la planche de glisse dans l'une de plusieurs positions prédéterminées. Les positions prédéterminées sont définies par la position des crantages / indexations complémentaires 232. Pour pouvoir basculer l'élément d'arrêt 16 de sa position inactive vers sa position active, le dispositif de retenue 1 doit être positionné par rapport à l'interface 2 dans une de plusieurs positions longitudinales prédéterminées. Pour chacune de ces positions longitudinales prédéterminées, un ergot 221 de l'interface 2 va coopérer avec un orifice 114 de l'embase 11. Ces positions longitudinales sont ainsi des positions indexées, relativement stables, permettant chacune, le basculement de l'élément d'arrêt 16 de sa position inactive vers sa position active. De plus, pour faciliter le réglage de la position longitudinale du dispositif de retenue, l'embase peut comprendre un ou plusieurs repères 119 destinés à coopérer respectivement avec une ou plusieurs graduations 201 ménagées sur la surface supérieure 20 de l'interface, comme on le voit sur les figures 1 à 5. Ainsi, l'utilisateur dispose d'un repère visuel permettant de déterminer la position longitudinale exacte de l'embase par rapport à l'interface. D'autres modes de réalisation de cet indicateur visuel peuvent être envisagés.In its upper part, the stop element 16 comprises a lower extension 163 projecting from the lower face 111 of the base 11 when the stop element is assembled on the base. This lower extension 163 comprises two notches 1631 oriented in a direction Y, transverse to the base when the stop element is assembled on the base. The notches 1631 are dimensioned and arranged so that they can cooperate with the complementary indexings 232 of the base when the stop element is in its active position and so that they no longer cooperate with the complementary indexings 232 of the base when the stop element is in its inactive position. In the latter case, the lower extension 163 is positioned in the central longitudinal groove 233. Thus, when it is in its inactive position, the stop element 16 can move along the interface 11, in the central longitudinal groove 233. On the other hand, when it is in its active position, the stop element 16 is integral with the interface 11 in the longitudinal direction X because the notches 1631 are engaged with the complementary indexings 232 of the base. The stop element 16 therefore allows the immobilization of the retaining device along the gliding board in one of several predetermined positions. The predetermined positions are defined by the position of the notches/complementary indexings 232. To be able to tilt the stop element 16 from its inactive position to its active position, the retaining device 1 must be positioned with respect to the interface 2 in one of several predetermined longitudinal positions. For each of these predetermined longitudinal positions, a lug 221 of the interface 2 will cooperate with an orifice 114 of the base 11. These longitudinal positions are thus indexed positions, relatively stable, each allowing the tilting of the stop element 16 from its inactive position to its active position. In addition, to facilitate adjustment of the longitudinal position of the retaining device, the base may comprise one or more marks 119 intended to cooperate respectively with one or more graduations 201 made on the upper surface 20 of the interface, as shown see on the figures 1 to 5 . Thus, the user has a visual cue to determine the exact longitudinal position of the base relative to the interface. Other embodiments of this visual indicator can be envisaged.

Dans cet exemple, l'élément d'arrêt 16 est dimensionné et positionné de sorte qu'il se loge dans la cavité délimitée par l'organe d'actionnement 14 et la face supérieure 116 de l'embase, lorsque l'élément d'arrêt est en position active. Dans cette configuration, l'organe d'actionnement 14 recouvre entièrement l'élément d'arrêt 16 ce qui permet de le protéger des intempéries lorsque l'utilisateur skie.In this example, the stop element 16 is sized and positioned so that it is housed in the cavity delimited by the actuating member 14 and the upper face 116 of the base, when the stop is in the active position. In this configuration, the actuating member 14 entirely covers the stopper 16 which makes it possible to protect it from bad weather when the user is skiing.

Selon l'invention, le dispositif de retenue comprend également un moyen 18 de verrouillage mobile entre une position de verrouillage, représentée à la figure 8, pour laquelle le moyen de verrouillage est apte à coopérer avec l'élément d'arrêt 16 de sorte à le maintenir dans sa configuration active et une position de déverrouillage, représentée à la figure 7, pour laquelle le moyen de verrouillage mobile est dans une configuration permettant le basculement de l'élément d'arrêt de sa position active vers sa position inactive. Le moyen de verrouillage 18 comprend un élément d'interférence 142 qui est apte à s'interférer avec une partie de l'élément d'arrêt 16 lorsqu'il se déplace de sa position active vers sa position inactive. La course de l'élément d'arrêt pour basculer d'une position active vers une position inactive est alors limitée de sorte que l'élément d'arrêt permet toujours la solidarisation entre le dispositif de retenue et l'interface selon sa direction longitudinale X. Lorsque le moyen de verrouillage bascule en position de déverrouillage, l'élément d'interférence 142 s'escamote, libérant alors la course de l'élément d'arrêt qui peut donc basculer en position inactive.According to the invention, the retaining device also comprises a locking means 18 movable between a locking position, shown in figure 8 , for which the locking means is adapted to cooperate with the stop element 16 so as to maintain it in its active configuration and an unlocked position, shown in figure 7 , for which the movable locking means is in a configuration allowing the tilting of the stop element from its active position to its inactive position. The locking means 18 comprises an interference element 142 which is adapted to interfere with a part of the stop element 16 when it moves from its active position to its inactive position. The travel of the stop element to switch from an active position to an inactive position is then limited so that the stop element always allows the attachment between the retaining device and the interface in its longitudinal direction X When the locking means swings into the unlocked position, the interference element 142 retracts, then releasing the travel of the stop element which can therefore swing into the inactive position.

Selon le mode de réalisation de l'invention illustré, le moyen de verrouillage 18 est une partie 142 de l'organe d'actionnement 14. La position de verrouillage correspond à la position de l'organe d'actionnement quand il est abaissé alors que la position de déverrouillage correspond à la position de l'organe d'actionnement quand il est relevé. L'élément d'interférence 142 est réalisé par une nervure interne faisant saillie de la surface définissant l'évidement inférieur 141 de l'organe d'actionnement 14. Lorsque le moyen d'actionnement est dans sa position de verrouillage et que l'élément d'arrêt est dans sa position active, comme représenté à la figure 8, l'élément d'interférence 142 vient se positionner en vis-à-vis de la première surface d'actionnement 1611 de l'élément d'arrêt, empêchant alors le mouvement de l'élément d'arrêt vers sa position inactive.According to the illustrated embodiment of the invention, the locking means 18 is a part 142 of the actuator 14. The locking position corresponds to the position of the actuator when it is lowered while the unlocking position corresponds to the position of the actuating member when it is raised. The interference element 142 is produced by an internal rib protruding from the surface defining the lower recess 141 of the actuating member 14. When the actuating means is in its locking position and the element stopper is in its active position, as shown in figure 8 , the interference element 142 is positioned opposite the first actuating surface 1611 of the stop element, thus preventing the movement of the stop element towards its inactive position.

Selon un mode de réalisation, le moyen de verrouillage 18 comprend un élément d'interférence 142 dimensionné et agencé de sorte qu'il soit apte à interagir avec l'élément d'arrêt pour le faire basculer de sa position inactive vers sa position active lorsque le moyen de verrouillage bascule de sa position de déverrouillage vers sa position de verrouillage. L'interaction entre l'élément d'interférence 142 et l'élément d'arrêt 16 peut être réalisée par un contact direct. Dans cet exemple, la nervure interne 142 présente une surface complémentaire à la première surface d'actionnement 1611 apte à venir en contact avec une portion de la première surface d'actionnement 1611, lors de l'abaissement de l'organe d'actionnement 14, lorsque l'élément d'arrêt 16 est en position inactive. Ainsi, lorsque l'utilisateur abaisse l'organe d'actionnement, la nervure interne vient en en contact avec la première surface d'actionnement de l'élément d'arrêt. Puis, en poursuivant la rotation de l'organe d'actionnement pour amener la mâchoire mobile dans sa position d'enclenchement, du fait de la complémentarité des surfaces inclinées, l'élément d'interférence 142 pousse l'élément d'arrêt pour le faire basculer de sa position inactive vers sa position active. Grâce à cette construction, le basculement de la mâchoire mobile vers sa position d'enclenchement entraîne simultanément le verrouillage de l'élément d'arrêt et donc l'immobilisation longitudinale du dispositif de retenue par rapport au ski. On obtient donc un verrouillage automatique en actionnant le mécanisme de maintien 17 pour solidariser la chaussure avec le dispositif de retenue. Ainsi, avec une seule manipulation, l'utilisateur peut à la fois solidariser sa chaussure avec la fixation et verrouiller le réglage de la position longitudinale du dispositif de retenue.According to one embodiment, the locking means 18 comprises an interference element 142 sized and arranged so that it is capable of interacting with the stop element to make it switch from its inactive position to its active position when the locking means tilts from its unlocking position to its locking position. The interaction between the interference element 142 and the stop element 16 can be achieved by direct contact. In this example, the internal rib 142 has a surface complementary to the first actuation surface 1611 capable of coming into contact with a portion of the first actuation surface 1611, when the actuation member 14 is lowered. , when the stop element 16 is in the inactive position. Thus, when the user lowers the actuating member, the internal rib comes into contact with the first actuating surface of the stop element. Then, by continuing the rotation of the actuating member to bring the mobile jaw into its engagement position, due to the complementarity of the inclined surfaces, the interference element 142 pushes the stop element for the switch from its inactive position to its active position. Thanks to this construction, the tilting of the mobile jaw towards its engagement position simultaneously causes the locking of the stop element and therefore the longitudinal immobilization of the retaining device with respect to the ski. Automatic locking is therefore obtained by actuating the holding mechanism 17 to secure the boot to the retaining device. Thus, with a single manipulation, the user can both secure his shoe with the binding and lock the adjustment of the longitudinal position of the retention device.

L'invention porte sur le fait que le moyen de verrouillage 18 est cinématiquement lié à la mâchoire mobile 13 de sorte que, lorsque le moyen de verrouillage est dans sa position de verrouillage, la mâchoire mobile est systématiquement dans sa position d'enclenchement. Au sens de l'invention, une pièce est cinématiquement liée à la mâchoire mobile 13 lorsqu'il y a une relation entre la position de la pièce et la position de la mâchoire mobile. Ainsi, pour une position déterminée de la pièce, cette liaison induit une position déterminée de la mâchoire. La pièce peut être directement fixée sur la mâchoire mobile ou son corps. En conséquence, un mouvement de translation de la mâchoire mobile entraîne la même translation de la pièce associée. Alternativement, la pièce peut être montée mobile par rapport à la mâchoire mobile ou son corps. Dans ce cas, un mouvement de translation de la mâchoire mobile entraîne un mouvement de la pièce associée. Par exemple, ce peut être une rotation de la pièce par rapport au corps de la mâchoire mobile, grâce aux biellettes, comme dans le mode de réalisation de l'invention illustré.The invention relates to the fact that the locking means 18 is kinematically linked to the mobile jaw 13 so that, when the locking means is in its locking position, the mobile jaw is systematically in its engagement position. Within the meaning of the invention, a part is kinematically linked to the movable jaw 13 when there is a relationship between the position of the part and the position of the movable jaw. Thus, for a determined position of the part, this connection induces a determined position of the jaw. The part can be directly fixed on the movable jaw or its body. Consequently, a translational movement of the mobile jaw causes the same translation of the associated part. Alternatively, the part can be mounted movably relative to the movable jaw or its body. In this case, a translational movement of the movable jaw causes a movement of the associated part. For example, it may be a rotation of the part relative to the body of the movable jaw, thanks to the connecting rods, as in the illustrated embodiment of the invention.

Dans cet exemple, le moyen de verrouillage 18 est une partie 142 de l'organe d'actionnement 14 du mécanisme de maintien 17 et donc, par construction, directement lié à la cinématique de la mâchoire mobile. Dans une variante, le moyen de verrouillage peut être une autre pièce du mécanisme de maintien 17. Ce peut être, par exemple, un élément porté par le corps de la mâchoire mobile. Grâce à l'invention, quand la chaussure est en prise avec le dispositif de retenue, l'utilisateur est assuré que le dispositif de retenue est bloqué longitudinalement sur le ski.In this example, the locking means 18 is a part 142 of the actuating member 14 of the holding mechanism 17 and therefore, by construction, directly linked to the kinematics of the mobile jaw. Alternatively, the locking means may be another part of the holding mechanism 17. This can be, for example, an element carried by the body of the movable jaw. Thanks to the invention, when the boot is in engagement with the retaining device, the user is assured that the retaining device is locked longitudinally on the ski.

Selon un mode de réalisation de l'invention, le dispositif de retenue est directement fixé sur la planche de glisse, sans une pièce d'interface distincte. Dans ce cas, la face supérieure du ski intègre les éléments permettant l'assemblage du dispositif de retenue sur le ski.According to one embodiment of the invention, the retaining device is fixed directly to the gliding board, without a separate interface piece. In this case, the upper face of the ski incorporates the elements allowing the assembly of the retaining device on the ski.

On peut envisager d'autres modes de réalisation de l'invention du mécanisme de maintien en position d'un élément d'accrochage appartenant à la chaussure. Par exemple, la mâchoire mobile peut être positionnée en arrière sur le dispositif de retenue par rapport à la mâchoire fixe. Le mécanisme de maintien peut ne pas avoir de mâchoire fixe. Par exemple, la mâchoire mobile peut être réalisée par deux pointes mobiles transversalement, disposées symétriquement par rapport au plan médian longitudinal du ski, chaque pointe étant apte à coopérer avec un logement ménagé sur un bord latéral de l'avant de la semelle de la chaussure. Une telle construction est illustrée, par exemple, dans le document EP-A-0199098 . De même, on peut envisager d'autres solutions d'organe d'actionnement. Ce peut être un bouton rotatif ou un poussoir.It is possible to envisage other embodiments of the invention of the mechanism for maintaining in position an attachment element belonging to the shoe. For example, the movable jaw can be positioned rearward on the retainer relative to the fixed jaw. The holding mechanism may not have a fixed jaw. For example, the movable jaw can be produced by two transversely movable spikes, arranged symmetrically with respect to the longitudinal median plane of the ski, each spike being capable of cooperating with a housing provided on a lateral edge of the front of the sole of the boot. . Such a construction is illustrated, for example, in the document EP-A-0199098 . Similarly, it is possible to envisage other actuating member solutions. It can be a rotary button or a push button.

Par ailleurs, on peut également envisager d'autres constructions d'élément d'arrêt longitudinal. Par exemple, l'élément d'arrêt peut coopérer avec des indexations complémentaires selon une direction Z, normale à la surface supérieure de l'interface. L'élément d'arrêt peut être couplé avec un moyen élastique de sorte à le maintenir dans une position stable, par exemple, sa position active.Furthermore, other longitudinal stop element constructions can also be envisaged. For example, the stop element can cooperate with complementary indexings in a direction Z, normal to the upper surface of the interface. The stop element can be coupled with an elastic means so as to maintain it in a stable position, for example, its active position.

Comme nous avons vu précédemment, le dispositif de retenu comprend un moyen de maintien permettant de maintenir l'élément d'arrêt longitudinal dans une position active stable, indépendamment de la position du moyen de verrouillage. Ce moyen de maintien peut être un moyen élastique comme cela vient d'être évoqué. Alternativement, comme illustré sur la figure 8, le moyen de maintien comprend un élément de positionnement (1623) de l'élément d'arrêt longitudinal et un élément de positionnement complémentaire (118) du dispositif de retenue, aptes à coopérer ensemble. Plus généralement, le moyen de maintien comprend un élément de positionnement de l'élément d'arrêt longitudinal et un élément de positionnement complémentaire solidaire de l'engin, aptes à coopérer ensemble. Selon un autre mode de réalisation de l'invention non illustré, l'élément de positionnement complémentaire est solidaire des indexations complémentaires (232) coopérant avec l'élément d'arrêt longitudinal. D'autres moyens de maintien de l'élément d'arrêt longitudinal dans une position active stable peuvent être envisagés.As we have seen previously, the retaining device comprises a holding means making it possible to hold the longitudinal stop element in a stable active position, independently of the position of the locking means. This holding means can be an elastic means as has just been mentioned. Alternatively, as shown in figure 8 , the holding means comprises a positioning element (1623) of the longitudinal stop element and a complementary positioning element (118) of the retaining device, capable of cooperating together. More generally, the holding means comprises a positioning element of the longitudinal stop element and a complementary positioning element secured to the machine, capable of cooperating together. According to another embodiment of the invention not shown, the complementary positioning element is integral with the complementary indexings (232) cooperating with the longitudinal stop element. Other means of maintaining the longitudinal stop element in a stable active position can be envisaged.

Comme il apparait clairement dans le mode de réalisation de l'invention décrit, le dispositif est conçu de sorte que l'élément d'arrêt longitudinal est apte à conserver une position active stable lorsque la mâchoire mobile est dans sa position de libération.As clearly appears in the embodiment of the invention described, the device is designed so that the longitudinal stop element is capable of maintaining a stable active position when the movable jaw is in its release position.

L'invention n'est pas limitée à ces modes de réalisation. Il est possible de combiner ces modes de réalisation.The invention is not limited to these embodiments. It is possible to combine these embodiments.

L'invention n'est pas limitée aux modes de réalisation précédemment décrits mais s'étend à tous les modes de réalisation couverts par les revendications annexées.The invention is not limited to the embodiments previously described but extends to all the embodiments covered by the appended claims.
