Description

L'invention concerne un élément de liaison réglable sur une planche de glisse pour un dispositif de fixation d'une chaussure sur une planche de glisse, comme par exemple un dispositif de fixation avant appelé « butée » ou un dispositif de fixation arrière appelé « talonnière » d'un dispositif de fixation de chaussure sur un ski, ou par exemple une embase d'un dispositif de fixation d'une chaussure sur un surf ou « snowboard ». Elle concerne aussi un dispositif de fixation de chaussure en tant que tel lié à un tel élément réglable, et une planche de glisse en tant que telle.The invention relates to an adjustable binding element on a gliding board for a device for attaching a boot to a gliding board, such as for example a front fixing device called a "stop" or a rear fixing device called "heel piece". "A shoe attachment device on a ski, or for example a base of a device for attaching a shoe on a surf or" snowboard ". It also relates to a shoe attachment device as such linked to such an adjustable element, and a gliding board itself.

Dans l'état de la technique, différents dispositifs permettent un réglage de la position longitudinale d'une butée ou d'une talonnière d'un dispositif de fixation de chaussure sur un ski, dans le but d'adapter le dispositif de fixation à différentes pointures de chaussures de ski. Une solution courante est basée d'une part sur un premier élément positionné sur le ski comportant des rails de guidage et une partie dentée, et d'autre part sur une talonnière ou une butée dont l'embase est munie de rails de guidage et d'une partie dentée complémentaires. Les deux parties dentées complémentaires peuvent être imbriquées et bloquer le déplacement longitudinal de la talonnière ou de la butée dans les rails, dans une position de fixation longitudinale pour la pratique du ski. Un moyen de libération de ces parties dentées permet d'obtenir un déplacement de la talonnière ou butée pour le réglage de sa position.In the state of the art, various devices allow adjustment of the longitudinal position of a stop or heel of a shoe attachment device on a ski, in order to adapt the attachment device to different sizes of ski boots. A common solution is based firstly on a first element positioned on the ski having guide rails and a toothed portion, and secondly on a heel or a stop whose base is provided with guide rails and a complementary toothed part. The two complementary toothed parts can be nested and block the longitudinal displacement of the heel or stop in the rails, in a longitudinal fixing position for the practice of skiing. A means of releasing these toothed parts makes it possible to move the heel or abutment for the adjustment of its position.

Toutefois, les solutions existantes présentent toutes certains des inconvénients suivants :

  • elles nécessitent un outil comme un tournevis pour libérer les parties dentées. Cet outil doit être introduit par une ouverture et maintenu en position durant le réglage. Dans ce cas, les solutions ne sont pas conviviales et peu adaptées à des réglages rapides et dans toutes conditions, comme par exemple sur les pistes de ski où l'outil spécifique n'est pas toujours disponible ; et/ou,
  • elles sont complexes, car basées soit sur un grand nombre de composants, soit sur des éléments complexes à fabriquer ou monter : cela les rend coûteuses, moins fiables, peu conviviales et incompatibles avec les butées ou talonnières standard existantes ; et/ou,
  • elles sont parfois peu esthétiques car des éléments mécaniques peu esthétiques sont visibles ; et/ou,
  • elles sont encombrantes et augmentent le volume global de l'accessoire à monter sur la planche de glisse ; et/ou,
  • elles ne sont pas sûres, c'est à dire qu'elles peuvent entraîner des déréglages accidentels de la position de l'accessoire durant son utilisation, ce qui est dangereux car cela peut entraîner la chute du skieur ; et/ou
  • elles peuvent présenter des jeux qui nuisent à leur performance et à leur sécurité.
However, existing solutions all have some of the following disadvantages:
  • they require a tool like a screwdriver to release the toothed parts. This tool must be inserted through an opening and held in position during adjustment. In this case, the solutions are not user-friendly and unsuitable for quick adjustments and in all conditions, such as on ski slopes where the specific tool is not always available; and or,
  • they are complex, because based on a large number of components, or on complex elements to manufacture or mount: it makes them expensive, less reliable, not very user-friendly and incompatible with the existing standard stops or heels; and or,
  • they are sometimes unattractive because unattractive mechanical elements are visible; and or,
  • they are bulky and increase the overall volume of the accessory to be mounted on the gliding board; and or,
  • they are not safe, that is to say that they can cause accidental adjustment of the position of the accessory during use, which is dangerous because it can cause the fall of the skier; and or
  • they may present games that affect their performance and security.

Le document EP2147704 décrit une solution sans outil permettant de pallier à une bonne partie des inconvénients mentionnés ci-dessus.The document EP2147704 describes a solution without tools to overcome many of the disadvantages mentioned above.

Toutefois, il existe toujours un besoin d'une solution améliorée, simple, conviviale, sécurisée et fiable pour la liaison réglable d'un dispositif de fixation de chaussure sur une planche de glisse.However, there is still a need for an improved, simple, user-friendly, secure and reliable solution for the adjustable binding of a shoe attachment device to a gliding board.

Un objet général de la présente invention est donc de proposer une solution de liaison réglable d'un dispositif de fixation de chaussure sur une planche de glisse, qui ne présente pas tout ou partie des inconvénients de l'état de la technique.A general object of the present invention is therefore to provide an adjustable binding solution of a shoe attachment device on a gliding board, which does not have all or part of the disadvantages of the state of the art.

Pour faciliter la description suivante, nous définissons par convention la direction longitudinale pour la direction dans le sens du réglage d'une butée de fixation de chaussure sur un ski, c'est-à-dire aussi dans la direction longitudinale du ski, de l'arrière vers l'avant, la direction transversale pour la direction horizontale perpendiculaire à la direction longitudinale. La direction verticale est perpendiculaire aux deux autres directions et orientée vers le haut, perpendiculairement à la surface de la planche de glisse, non représentée.To facilitate the following description, we define by convention the longitudinal direction for the direction in the direction of adjustment of a shoe attachment stop on a ski, that is to say also in the longitudinal direction of the ski, the rearward forwards, the transverse direction for the horizontal direction perpendicular to the longitudinal direction. The vertical direction is perpendicular to the other two directions and oriented upwards, perpendicular to the surface of the gliding board, not shown.

L'invention va être illustrée dans le cadre de la fixation réglable dans la direction longitudinale d'une butée d'un dispositif de fixation d'une chaussure sur un ski. Elle pourrait toutefois être implémentée pour la fixation de la talonnière du dispositif de fixation de chaussure, ou plus généralement pour la fixation réglable de tout dispositif de fixation de chaussure sur toute planche de glisse, incluant le snowboard par exemple. Ainsi, elle peut être implémentée pour le réglage d'un dispositif de fixation de chaussure dans une direction de réglage différente de la direction longitudinale, par exemple transversale dans l'exemple d'une embase d'un dispositif de fixation de chaussure sur un snowboard.The invention will be illustrated in the context of the adjustable attachment in the longitudinal direction of a stop of a fastening device of a boot on a ski. It could however be implemented for fixing the heel of the shoe attachment device, or more generally for the adjustable attachment of any shoe attachment device on any board, including snowboard for example. Thus, it can be implemented for adjusting a shoe attachment device in a direction of adjustment different from the longitudinal direction, for example transverse in the example of a base of a shoe attachment device on a snowboard .

Selon le mode d'exécution de l'invention, un système de liaison d'une butée 1 sur un ski repose sur un élément de liaison 10 supérieur, qui se présente sous la forme d'une embase de la butée 1, et sur un second élément 50 inférieur, en forme d'embase inférieure, destinée à une fixation à la surface d'un ski, non représenté. La butée comprend un corps supérieur principal 2 comprenant dans sa partie arrière deux mâchoires 3 aptes à l'emprise de la partie avant d'une chaussure de ski, de manière connue. En remarque, l'élément de liaison 10 se présente ici comme un élément distinct de la butée 1 mais il pourrait en variante être intégré à la butée ou à un corps de la butée, formant un élément non dissociable. De même, le second élément 50 inférieur est distinct du ski dans ce mode de réalisation, mais il pourrait en variante être intégré directement dans la structure du ski.According to the embodiment of the invention, a system for connecting a stop 1 on a ski rests on an upper connecting element 10, which is in the form of a base of the abutment 1, and on a second lower element 50, in the form of a lower base, intended for attachment to the surface of a ski, not shown. The stop includes a body upper main 2 comprising in its rear part two jaws 3 adapted to the grip of the front portion of a ski boot, in a known manner. Note, the connecting element 10 is here as a separate element of the abutment 1 but it could alternatively be integrated with the abutment or a body of the abutment, forming a non-separable element. Similarly, the second lower element 50 is distinct from the ski in this embodiment, but could alternatively be integrated directly into the ski structure.

Comme cela apparaît sur la figure 1, puis sur les figures 8 à 11, le second élément 50 du système de liaison de la butée 1 sur un ski comprend des glissières 51 longitudinales agencées sur ses extrémités latérales, dont la section transversale présente une forme en U couché orienté vers l'extérieur dans ce mode de réalisation. Naturellement, d'autres formes de glissières sont envisageables. Elle comprend de plus un élément de blocage 58, sous la forme d'une partie longitudinale crantée formée au sein d'une plaque métallique sensiblement horizontale, comprenant plusieurs crans s'étendant dans la direction longitudinale pour permettre le réglage longitudinal de la butée par le choix du (ou des) cran(s), chaque cran se présentant sous la forme d'une fente transversale. Enfin, cette embase inférieure comprend des ouvertures 59 prévues pour sa fixation à la surface d'un ski, à l'aide de plusieurs vis traversant ces ouvertures 59. En variante, tout autre moyen de blocage est envisageable.As it appears on the figure 1 , then on the Figures 8 to 11 , the second element 50 of the connecting system of the abutment 1 on a ski comprises longitudinal slides 51 arranged on its lateral ends, the cross section of which has an outwardly facing U-shaped shape in this embodiment. Of course, other forms of slides are possible. It further comprises a locking element 58, in the form of a notched longitudinal portion formed within a substantially horizontal metal plate, comprising a plurality of notches extending in the longitudinal direction to allow the longitudinal adjustment of the stop by the choice of the (or) notch (s), each notch being in the form of a transverse slot. Finally, this lower base comprises openings 59 provided for its attachment to the surface of a ski, with the aid of several screws passing through these openings 59. In a variant, any other locking means is conceivable.

L'élément de liaison 10 est plus particulièrement représenté par les figures 2 à 7. Il comprend d'abord des glissières latérales 11 de forme correspondant aux glissières 51 de l'embase inférieure, pour permettre sa retenue dans la direction verticale et son guidage longitudinal relativement à l'embase inférieure et donc relativement au ski, pour le réglage longitudinal de la position de la butée 1. Il comprend de plus un levier 20 lié à un élément de réglage s'étendant longitudinalement dans sa partie centrale, se présentant sous la forme d'une tige longitudinale, que nous appellerons tringle 12. La tringle est sensiblement tubulaire. Elle présente une surface extérieure sensiblement cylindrique, à l'exception de quelques zones fonctionnelles décrites ci-après. Elle est mobile en rotation autour d'un axe longitudinal 40, par l'intermédiaire du levier 20 disposé vers sa partie arrière, et solidaire de la tringle. Vers l'extrémité avant de la tringle 12, un ressort de rappel 19 est agencé, de sorte à appliquer à la tringle un moment de rappel vers la position de fermeture du levier. La tringle 12 comprend vers sa partie centrale un élément de blocage 13, se présentant sous la forme d'une zone de plus grand diamètre de la tige dans laquelle sont agencés plusieurs crans 14, adaptés pour coopérer ou non avec la partie longitudinale crantée de l'embase inférieure. Ces deux éléments de blocage 13, 58 forment ainsi un dispositif de blocage dans la direction longitudinale (de réglage), par crantage selon le mode de réalisation de l'invention, qui permet la fixation réglable de la butée comme cela sera détaillé par la suite. Naturellement, cette fonction de fixation peut être remplacée par tout mécanisme équivalent, comme des parties dentées. La tringle et/ou les crans des éléments de blocage 13, 58 se présentent avantageusement en métal, ou en variante dans un plastique renforcé par des fibres.The connecting element 10 is more particularly represented by the Figures 2 to 7 . It comprises first of all lateral slides 11 of shape corresponding to the slides 51 of the lower base, to allow its retention in the vertical direction and its longitudinal guide relative to the lower base and therefore relative to the ski, for the longitudinal adjustment of the position of the stop 1. It further comprises a lever 20 connected to an adjusting element extending longitudinally in its part central, being in the form of a longitudinal rod, which we will call rod 12. The rod is substantially tubular. It has a substantially cylindrical outer surface, with the exception of a few functional areas described below. It is rotatable about a longitudinal axis 40, via the lever 20 disposed towards its rear portion, and secured to the rod. Towards the front end of the rod 12, a return spring 19 is arranged, so as to apply to the rod a moment of return to the closed position of the lever. The rod 12 comprises towards its central part a blocking element 13, in the form of a zone of greater diameter of the rod in which are arranged several notches 14, adapted to cooperate or not with the longitudinal notched part of the lower base. These two locking elements 13, 58 thus form a locking device in the longitudinal (adjustment) direction, notching according to the embodiment of the invention, which allows the adjustable attachment of the stop as will be detailed later . Naturally, this fixing function can be replaced by any equivalent mechanism, such as toothed parts. The bead and / or the notches of the locking elements 13, 58 are advantageously made of metal, or alternatively in a fiber-reinforced plastic.

La figure 14 illustre ainsi schématiquement une variante de réalisation dans laquelle les glissières 51 du second élément 50 sont orientées vers l'intérieur et reçoivent ainsi l'élément de liaison 10 dont les parties latérales formant glissières 11 sont simplifiées. Dans ces réalisations, des représentations en forme de U sont choisies pour les glissières, dans lesquelles les fonctions de maintien et de guidage sont mises en oeuvre avec des surfaces verticales et/ou horizontales. Toutefois, selon une autre réalisation représentée par les figures 15 et 16, les glissières 11, 51 correspondantes pourraient comprendre une surface biaisée (respectivement 22, 52), ni horizontale, ni verticale, pour améliorer leur coopération et leur efficacité dans la fonction de rattrapage des jeux.
La tringle 12 comprend de plus quatre éléments d'actionnement 15, agencés directement sur la circonférence de la tringle, dont le diamètre est localement modifié pour obtenir des parties non symétriques autour de l'axe 40 de la tringle 12, qui forment des surfaces arrondies 18 agissant comme des surfaces de came. Ces éléments d'actionnement 15 coopèrent avec des composants à rattrapage de jeu 25, selon un fonctionnement qui va être détaillé par la suite. Chaque composant à rattrapage de jeu 25 est monté mobile en translation transversale au sein de l'élément de liaison 10, dans des logements 21, et comprend une extrémité latérale 27 présentant une forme de glissière, avec une section en U, qui se substitue localement à la glissière 11 de l'élément de liaison 10. Chaque composant à rattrapage de jeu comprend de plus une encoche 28 coopérant avec la tringle 12, pour mettre en oeuvre son déplacement transversal et la fonction de rattrapage des jeux. En remarque, la tringle 12 comprend au moins un élément d'actionnement 15 et un élément de blocage 13 disposés en deux positions distinctes le long de son axe. De plus, l'élément de liaison comprend au moins un composant de rattrapage des jeux 25 distinct de l'élément de blocage 13.The figure 14 schematically illustrates an alternative embodiment in which the slides 51 of the second member 50 are oriented inwardly and thus receive the connecting element 10, the lateral portions forming slideways 11 are simplified. In these embodiments, U-shaped representations are chosen for the slides, in which the holding and guiding functions are implemented with vertical and / or horizontal surfaces. However, according to another embodiment represented by figures 15 and 16 , the slides 11, 51 corresponding could include a skewed surface (22, 52), neither horizontal nor vertical, to improve their cooperation and their effectiveness in the catch-up function of the games.
The rod 12 further comprises four actuating elements 15, arranged directly on the circumference of the rod, whose diameter is locally modified to obtain unsymmetrical portions around the axis 40 of the rod 12, which form rounded surfaces. 18 acting as cam surfaces. These actuating elements 15 cooperate with play-catching components 25, according to an operation which will be detailed later. Each play-catching component 25 is mounted to move transversely within the connecting element 10, in housings 21, and comprises a lateral end 27 having a slider shape, with a U-shaped section, which locally replaces to the slide 11 of the connecting element 10. Each game-catching component further comprises a notch 28 cooperating with the rod 12, to implement its transverse displacement and the catch-up function games. As a remark, the rod 12 comprises at least one actuating element 15 and a locking element 13 arranged in two distinct positions along its axis. In addition, the connecting element comprises at least one clearance component 25 separate from the locking element 13.

Le fonctionnement de ce système de liaison d'une butée 1 sur un ski va maintenant être expliqué, en référence aux figures 8 à 11.The operation of this binding system of a stop 1 on a ski will now be explained, with reference to Figures 8 to 11 .

La figure 8 montre le système de liaison en coupe par un plan transversal vertical au niveau d'un cran 14 de l'élément de blocage 13 de la tringle 12. Le levier 20 est en position fermée, en butée sur une surface 17 de l'élément de liaison 10, agencée dans un logement pratiqué dans l'épaisseur en partie arrière de l'élément de liaison, qui permet de l'escamoter partiellement, pour éviter qu'il ne gêne le positionnement d'une chaussure lors de la pratique du ski. Dans cette position fermée du levier 20, chaque cran 14 occupe une position basse, dans laquelle au moins un cran coopère avec les crans complémentaires de l'élément de blocage 58 de l'embase inférieure. Dans cette configuration de blocage, les crans 14 empêchent donc tout déplacement longitudinal de l'élément de liaison 10 relativement au second élément 50 inférieur, assurant la fixation de la butée 1 relativement à un ski.The figure 8 shows the connection system in section through a vertical transverse plane at a notch 14 of the locking element 13 of the rod 12. The lever 20 is in the closed position, abutting on a surface 17 of the element of link 10, arranged in a housing made in the thickness at the rear of the connecting element, which allows to partially retract, to prevent it hinders the positioning of a shoe during skiing. In this closed position of lever 20, each notch 14 occupies a low position, in which at least one notch cooperates with the complementary notches of the locking element 58 of the lower base. In this locking configuration, the notches 14 thus prevent any longitudinal displacement of the connecting element 10 relative to the second element 50 below, ensuring the attachment of the stop 1 relative to a ski.

Lorsque le levier 20 est actionné manuellement, par sa rotation vers le haut, autour de son axe de rotation longitudinal correspondant à l'axe 40 de la tringle 12, il entraîne la rotation de la tringle autour de son axe, jusqu'à ce que les crans 14 échappent à l'élément de blocage 58 de l'embase inférieure. La géométrie des crans 14, qui s'étendent sur un angle d'environ 45 degrés autour de la tringle, est telle qu'ils échappent de leur emprise pour une rotation d'environ 90 degrés du levier 20. Dans la configuration d'ouverture du levier, l'élément de blocage 13 se trouve donc dans une position de replis et l'élément de liaison 10 devient ainsi mobile relativement à l'embase inférieure 50, permettant son déplacement longitudinal, guidé par la coopération des glissières respectives 11, 51 des deux éléments inférieur et supérieur du système de liaison. Ce dernier se trouve alors en configuration de réglage.When the lever 20 is actuated manually, by its upward rotation, about its longitudinal axis of rotation corresponding to the axis 40 of the rod 12, it causes the rotation of the rod about its axis, until the notches 14 escape the blocking element 58 of the lower base. The geometry of the notches 14, which extend about an angle of about 45 degrees around the rod, is such that they escape from their grip for a rotation of about 90 degrees of the lever 20. In the opening configuration of the lever, the locking element 13 is therefore in a folded position and the connecting element 10 thus becomes mobile relative to the lower base 50, allowing its longitudinal displacement, guided by the cooperation of the respective slideways 11, 51 of the two lower and upper elements of the connection system. The latter is then in setting configuration.

En remarque, pour rendre ce réglage convivial, malgré les conditions défavorables rencontrées sur une piste de ski, dues à la présence de neige, d'eau, de saletés, du froid, etc., un jeu 60 supérieur ou égal à 0,2 mm, et pouvant même aller jusqu'à 0,4 mm inclus est prévu entre les glissières respectives 11, 51 des embases supérieure et inférieure. Un tel jeu est notamment important entre les surfaces verticales 16, 56 en vis-à-vis des glissières respectives 11, 51. Ce jeu permet de garantir le bon coulissement relatif des deux éléments sans blocage au niveau des glissières malgré les circonstances défavorables mentionnées ci-dessus. En revanche, ce jeu présente l'inconvénient qu'en configuration de blocage du système de liaison, l'élément de liaison 10 risque de conserver une petite mobilité, notamment en rotation autour d'un axe vertical, voire autour d'un axe transversal, c'est-à-dire en torsion ou roulis. De tels mouvements sont perceptibles par le skieur, par exemple sous forme de vibrations, lui donnant une impression de manque de sécurité, voire pouvant dégrader ses performances sur la neige.As a note, to make this adjustment user-friendly, despite the adverse conditions encountered on a ski slope, due to the presence of snow, water, dirt, cold, etc., a game 60 greater than or equal to 0.2 mm, and even up to 0.4 mm inclusive is provided between the respective slides 11, 51 of the upper and lower bases. Such a game is particularly important between the vertical surfaces 16, 56 vis-à-vis the respective slides 11, 51. This game ensures good relative sliding of the two elements without blocking at the slides despite the adverse circumstances mentioned here. -above. However, this game has the disadvantage that in configuration of blocking the connecting system, the connecting element 10 may retain a small mobility, especially in rotation about a vertical axis, or around a transverse axis, that is to say, in torsion or roll. Such movements are perceptible by the skier, for example in the form of vibrations, giving him an impression of lack of security, or even may degrade his performance on the snow.

Pour pallier cet inconvénient, le système de liaison d'une butée 1 sur un ski comprend de plus un dispositif de rattrapage de jeu, actionné par l'intermédiaire du même levier 20, de manière coordonnée avec le mécanisme de blocage explicité précédemment. Pour cela, des éléments d'actionnement 15 sont disposés autour de la tringle 12, particulièrement visibles sur les figures 10 et 11 en coupe transverse au niveau de ces éléments d'actionnement 15, et sur l'agrandissement de la figure 13. Ils présentent une géométrie non symétrique autour de l'axe de rotation 40 de la tringle 12 formant une came. Ils sont solidaires de la tringle et mobiles en rotation avec la tringle 12, par l'intermédiaire du levier 20. Ils sont logés au sein d'un logement en forme de U formé par l'encoche 28 d'un composant de rattrapage des jeux 25, disposée au niveau de la partie centrale de l'élément de liaison 10. Cette encoche 28 comprend donc deux surfaces sensiblement verticales, une première surface 37 disposée vers la droite sur la figure 10 et une seconde surface 38 disposée vers la gauche, reliées par une surface sensiblement horizontale 39 qui s'étend sous la tringle 12. Par cette approche, la tringle 12 assure un maintien du composant de rattrapage des jeux 25, qui ne peut pas s'échapper vers le haut. Le composant de rattrapage des jeux 25 comprend une extrémité latérale 27 qui forme une glissière, destinée à coopérer avec la glissière 51 de l'embase inférieure. Pour cela, elle comprend une forme en U couché, dont l'extrémité inférieure vient se loger au sein de ladite glissière 51. Comme cela a été évoqué précédemment, cette forme de glissière pourrait être différente.To overcome this drawback, the connection system of a stop 1 on a ski further comprises a play retraction device, actuated via the same lever 20, in a coordinated manner with the locking mechanism explained above. For this, actuating elements 15 are arranged around the bead wire 12, particularly visible on the Figures 10 and 11 in transverse section at these actuating elements 15, and on the enlargement of the figure 13 . They have a non-symmetrical geometry around the axis of rotation 40 of the rod 12 forming a cam. They are secured to the rod and movable in rotation with the rod 12, via the lever 20. They are housed within a U-shaped housing formed by the notch 28 of a component of catching games 25, disposed at the central portion of the connecting element 10. This notch 28 thus comprises two substantially vertical surfaces, a first surface 37 disposed to the right on the figure 10 and a second surface 38 arranged to the left, connected by a substantially horizontal surface 39 which extends under the rod 12. By this approach, the rod 12 ensures a maintenance of the play catch component 25, which can not be used. escape to the top. The catch-up component of the games 25 comprises a lateral end 27 which forms a slide, intended to cooperate with the slide 51 of the lower base. For this, it comprises a coated U-shape, whose lower end is housed within said slide 51. As previously mentioned, this form of slide could be different.

La figure 10 illustre le système de liaison en configuration de blocage, le levier 20 occupant sa position fermée. La surface arrondie 18 en circonférence du composant d'actionnement 15 est en appui sur la surface verticale gauche 38 du composant de rattrapage des jeux 25 (celui de droite sur la figure 10), exerçant un effort transversal sur celui-ci tendant à translater ce composant de rattrapage des jeux 25 vers l'intérieur, assurant ainsi son maintien dans une première position stable de rattrapage des jeux, dans laquelle une surface sensiblement verticale 26 et longitudinale de son extrémité latérale 27 vient en butée sur la surface d'appui 56 verticale et longitudinale correspondante, située au fond de la glissière 51 de l'embase inférieure. La force de cet appui est prédéfinie par la forme du composant d'actionnement 15, de sorte à garantir la fonction de rattrapage des jeux. En remarque, dans cette première position, la surface horizontale 22, ou inclinée selon la variante de réalisation des figures 14 et 15, du haut de l'extrémité latérale 27 vient aussi de préférence en appui sur la surface haute 52 correspondante de la glissière 51.The figure 10 illustrates the connection system blocking configuration, the lever 20 occupying its closed position. The circumferentially rounded circumferential surface 18 of the actuating component 15 bears against the left vertical surface 38 of the play-catching component 25 (that on the right on the figure 10 ), exerting a transverse force on the latter tending to translate this catch-up component of the games 25 inwards, thus ensuring its maintenance in a first stable position of catch-up games, wherein a substantially vertical surface 26 and longitudinal of its lateral end 27 abuts on the bearing surface 56 vertical and longitudinal corresponding, located at the bottom of the slide 51 of the lower base. The force of this support is predefined by the shape of the actuating component 15, so as to guarantee the catch-up function of the games. As a remark, in this first position, the horizontal surface 22, or inclined according to the embodiment variant of the Figures 14 and 15 from the top of the lateral end 27 also preferably bears against the corresponding upper surface 52 of the slideway 51.

Lorsque le levier 20 est soulevé vers sa position ouverte pour atteindre la configuration de réglage, représentée sur la figure 11, le composant d'actionnement 15 agencé sur la tringle 12, plus particulièrement visible sur la figure 13, effectue de même une rotation de sorte que sa surface arrondie 18 périphérique vienne exercer une force sur la surface verticale droite 37 du composant de rattrapage des jeux 25, entraînant son déplacement transverse en translation vers l'extérieur vers une seconde position stable, induisant l'écartement des deux surfaces 26, 56 au sein de la glissière 51. Ainsi, dans cette configuration de réglage, les composants de rattrapage des jeux 25 libèrent aussi l'élément de liaison 10 qui acquière une bonne mobilité longitudinale. La figure 12 illustre aussi l'élément de liaison 10 en vue de dessus en configuration de réglage.When the lever 20 is raised to its open position to reach the setting configuration, shown in FIG. figure 11 , the actuating component 15 arranged on the rod 12, more particularly visible on the figure 13 , likewise rotates so that its rounded peripheral surface 18 exerts a force on the vertical straight surface 37 of the play-catching component 25, causing its transverse displacement in outward translation towards a second stable position, inducing the separating the two surfaces 26, 56 within the slideway 51. Thus, in this adjustment configuration, the catch-up components of the games 25 also release the connecting element 10 which acquires a good longitudinal mobility. The figure 12 also illustrates the connecting element 10 in top view in adjustment configuration.

La course latérale d'un composant de rattrapage des jeux 25 est réglée par la géométrie des composants d'actionnement 15 et de l'encoche 28 de chaque composant de rattrapage des jeux. De préférence, cette course est supérieure ou égale à 1 mm, voire supérieure ou égale à 1,5 mm, par exemple de 2 mm environ, et inférieure ou égale à 4 mm, voire 2,5 mm. Le déplacement des composants de rattrapage des jeux 25 est donc obtenu par la coopération de deux surfaces complémentaires, dont la surface périphérique 18 d'un composant d'actionnement, formant une came. Naturellement, un tel actionnement pourrait en variante être obtenu par une autre forme qu'une came, et plus généralement par tout autre mécanisme liant la tringle 12 au composant de rattrapage des jeux 25. D'autre part, un ressort de rappel pourrait agir sur un composant de rattrapage des jeux, pour le ramener automatiquement dans une des positions stables lors de l'actionnement de la tringle, notamment la seconde position stable de libération pour le réglage de la position de l'élément de liaison 10.The lateral travel of a play-catching component 25 is regulated by the geometry of the actuating components 15 and the notch 28 of each play-catching component. Preferably, this stroke is greater than or equal to 1 mm, or even greater than or equal to 1.5 mm, for example about 2 mm, and less than or equal to 4 mm, or even 2.5 mm. The displacement of the play catching components 25 is thus obtained by the cooperation of two complementary surfaces, the peripheral surface 18 of an actuating component, forming a cam. Naturally, such an actuation could alternatively be obtained by another shape than a cam, and more generally by any other mechanism linking the rod 12 to the catch-up component of the games 25. On the other hand, a return spring could act on a catch-up component for automatically returning it to one of the stable positions when the rod is actuated, in particular the second stable release position for adjusting the position of the connecting element 10.

Lors de la fermeture du levier 20 pour revenir vers la configuration de blocage du système de liaison, le composant de rattrapage des jeux se déplace d'abord librement en translation transversale vers l'intérieur selon une première course, avant d'arriver en contact avec la surface d'appui 56 au fond de la glissière 51 de l'élément inférieur, lorsque le levier a encore environ 45 degrés à parcourir. Ensuite, sur une seconde course correspondant à la fin de rotation du levier, le composant de rattrapage des jeux 25 ne se déplace plus, puisqu'il se trouve déjà en position de butée, mais exerce une force de plus en plus forte sur la surface d'appui 56 de la glissière.When closing the lever 20 to return to the blocking configuration of the connection system, the catch-up component of the games first moves freely in transverse translation inward in a first stroke, before coming into contact with the bearing surface 56 at the bottom of the slide 51 of the lower element, when the lever still has about 45 degrees to go. Then, on a second stroke corresponding to the end of rotation of the lever, the catch-up component of the games 25 no longer moves, since it is already in abutment position, but exerts an increasingly stronger force on the surface support 56 of the slide.

Sur le mode d'exécution choisi, quatre composants de rattrapage des jeux 25 sont prévus, agencés par deux couples de deux. Chaque couple comprend deux composants de rattrapage des jeux disposés en vis-à-vis, dont les deux encoches sont alignées dans le sens longitudinal pour recevoir un élément d'actionnement de la tringle, qui permet leur déplacement selon deux orientées opposées de part et d'autre du plan médian de l'élément de liaison, en remplissant une fonction de rattrapage des jeux de manière complémentaire et simultanée par des appuis sur deux surfaces opposées, sur chaque glissière latérale opposée, en exerçant des forces d'appui de même valeur dans des directions transverses opposées. Par cette construction sensiblement symétrique, les deux composants de rattrapage des jeux 25 droite et gauche présentent exactement la même géométrie, et peuvent être fabriqués facilement avec une optimisation des coûts, par exemple par injection plastique, à l'aide d'un seul moule d'injection. Ces composants de rattrapage des jeux pourraient par exemple être formés en polyamide chargé, voire en tout matériau plastique chargé. Naturellement, tout autre nombre de composant de rattrapage des jeux peut être prévu, au moins un, et de préférence un nombre pair pour exercer des efforts d'appui équivalents sur chaque côté latéral de l'élément de liaison. Le fait d'en utiliser quatre, dont deux vers l'avant et deux vers l'arrière, forme une solution optimisée pour le rattrapage de jeux.In the chosen embodiment, four game-catching components 25 are provided, arranged in pairs of two. Each couple comprises two play-catching components disposed facing each other, the two notches of which are aligned in the longitudinal direction to receive an actuating element of the rod, which allows their movement in two opposite directions on either side of the median plane of the connecting element, by performing a complementary and simultaneous game catch-up function by pressing on two opposite surfaces, on each opposite lateral slide, by exerting support forces of the same value in directions transverse opposite. By this substantially symmetrical construction, the two catch-up components of the right and left sets have exactly the same geometry, and can be easily manufactured with cost optimization, for example by plastic injection, with the aid of a single mold. 'injection. These catch-up components of the games could for example be formed of filled polyamide, or even any loaded plastic material. Naturally, any other number of play-catching component may be provided, at least one, and preferably an even number, for exerting equivalent support forces on each lateral side of the connecting element. The use of four, two forward and two backward, forms an optimized solution for the game catch-up.

Dans le mode de réalisation décrit, la fonction de rattrapage des jeux est remplie par des appuis en direction transversale, par l'intermédiaire de deux surfaces 26, 56 sensiblement parallèles à un plan vertical longitudinal. En variante, cet appui pourrait se faire selon une direction verticale, sur une surface horizontale, ou sur une combinaison de ces deux solutions sur une surface inclinée.In the embodiment described, the catch-up function of the games is filled by supports in transverse direction, via two surfaces 26, 56 substantially parallel to a longitudinal vertical plane. Alternatively, this support could be in a vertical direction, on a horizontal surface, or a combination of these two solutions on an inclined surface.

De plus, dans le mode d'exécution représenté, des surfaces d'appui des composants de rattrapage des jeux présentent de plus l'avantage d'être très écartées, puisqu'elles agissent au-niveau de surfaces vers les extrémités latérales : cela assure un rattrapage des jeux très performant, particulièrement efficace contre les jeux en roulis et torsion.Moreover, in the embodiment shown, bearing surfaces of the game-catching components also have the advantage of being widely spaced, since they act at the level of surfaces towards the surfaces. Lateral ends: this ensures a very effective game catch-up, particularly effective against the games in roll and torsion.

En variante, un composant de rattrapage des jeux pourrait remplir sa fonction avec un déplacement différent de celui illustré. Une première variante relativement proche consisterait à prévoir un appui sur la face intérieure d'une surface verticale longitudinale, donc dans une direction opposée à celle du mode de réalisation, orientée vers l'extérieur de l'élément de liaison, un composant de rattrapage des jeux se déplaçant donc dans une direction transversale vers l'extérieur pour venir en butée et supprimer les jeux, et vers l'intérieur pour libérer les deux éléments. Une autre variante de réalisation peut aussi facilement être obtenue en prévoyant que le ou les composant(s) de rattrapage des jeux se déplace(nt) sur toute autre butée que la glissière 51 servant de guidage au réglage de la position longitudinale des éléments 10, 50.As a variant, a catch-up component of the games could fulfill its function with a displacement different from that illustrated. A first relatively similar variant would consist in providing a bearing on the inside face of a vertical longitudinal surface, and therefore in a direction opposite to that of the embodiment, facing outwardly of the connecting element, a component for catching up the games moving in a direction transverse outwards to abut and remove the games, and inward to release the two elements. Another variant embodiment can also be easily obtained by providing that the component (s) catching the games moves (s) on any other abutment that the slide 51 serving to guide the adjustment of the longitudinal position of the elements 10, 50.

D'autre part, l'actionnement d'un composant de rattrapage des jeux pourrait se faire de manière différente à celle représentée, par une autre liaison mécanique entre la tringle et le composant. Un composant de rattrapage des jeux pourrait être animé d'un mouvement différent d'une translation, par exemple une rotation, ou une combinaison entre une rotation et une translation. Il pourrait aussi être animé d'une translation dans une autre direction que celle perpendiculaire à la tringle, par exemple parallèle à la tringle.On the other hand, the actuation of a catch-up component games could be different from that shown, by another mechanical connection between the rod and the component. A catch-up component of the games could be driven by a different movement of a translation, for example a rotation, or a combination between a rotation and a translation. It could also be driven in a direction other than that perpendicular to the rod, for example parallel to the rod.

D'autre part, les deux éléments formant le système de liaison pourraient se présenter selon une autre géométrie. Certains composants de l'un pourraient être agencés sur l'autre et inversement. Par exemple, la tringle pourrait être aménagée sur l'élément inférieur, de même qu'un composant de rattrapage des jeux. La tringle pourrait aussi présenter une autre forme que la tige tubulaire métallique du mode d'exécution. Elle pourrait par exemple se présenter sous la forme d'une tige plate. Selon un autre mode de réalisation, la tringle pourrait s'étendre selon un axe transversal à l'élément de liaison, la surface de came d'un élément d'actionnement 15 agissant alors sur un composant de rattrapage des jeux 25 selon un mécanisme lui permettant sa translation transversale comme dans le mode de réalisation précédent, donc parallèlement à la tringle.On the other hand, the two elements forming the connection system could be in another geometry. Some components of one could be arranged on the other and vice versa. For example, the rod could be arranged on the lower element, as well as a catch-up component games. The rod may also have a shape other than the tubular metal rod of the embodiment. It could by example be in the form of a flat shank. According to another embodiment, the bead wire could extend along an axis transverse to the connecting element, the cam surface of an actuating element 15 then acting on a catch-up component of the games 25 according to a mechanism allowing its transverse translation as in the previous embodiment, so parallel to the rod.

D'autre part, l'invention a été illustrée sur la base d'un levier mais un composant de rattrapage des jeux et/ou de blocage peut en variante être actionné par une cinématique différente, à partir de n'importe quel organe de préhension. Tout actionneur, sous forme d'un organe de préhension manipulable manuellement, solidaire ou non de la tringle, pourrait convenir. Cet organe peut par exemple se présenter sous la forme d'un organe mobile en translation et non en rotation. Selon une autre variante de réalisation, l'actionnement mentionné pourrait être obtenu à l'aide d'un outil, par exemple un tournevis par l'intermédiaire d'une encoche par exemple réalisée à l'extrémité arrière de la tringle, auquel cas aucun organe de préhension ne serait nécessaire.On the other hand, the invention has been illustrated on the basis of a lever but a catch-up component of the games and / or blocking can alternatively be actuated by a different kinematic, from any gripping member . Any actuator, in the form of a manually manipulable gripping member, integral or not with the rod, could be suitable. This member may for example be in the form of a movable member in translation and not in rotation. According to another embodiment, the mentioned operation could be obtained using a tool, for example a screwdriver through a notch for example made at the rear end of the rod, in which case no grasping organ would not be necessary.

Il convient de bien différencier dans ces solutions la fonction de blocage de la fonction de rattrapage des jeux : ces deux fonctions sont complémentaires et de nature différente. La fonction de blocage est obtenue par des éléments crantés ou dentés complémentaires, qui permettent la mise en place sur une planche de glisse d'un dispositif de fixation de chaussure qui résiste à des efforts très importants, et est ainsi adapté à la pratique du ski par exemple. La fonction de rattrapage des jeux se présente en général par un élément offrant un simple appui destiné à réduire, et même à supprimer, les mouvements parasites de l'élément de liaison, en particulier par rapport aux glissières selon le mode de réalisation. Outre ces différences structurelles, une seconde différence est fonctionnelle. Le blocage, malgré la présence de jeux, suffit pour résister aux contraintes exercées par un skieur par exemple. Au contraire, le rattrapage des jeux serait totalement insuffisant et inutile seul. Par nature, il doit être combiné à un élément de blocage. Ainsi, selon le mode de réalisation avantageux, le ou les composant(s) de rattrapage des jeux est/sont distinct(s) de l'élément de blocage.In these solutions, it is important to differentiate between the function of blocking the catch-up function of the games: these two functions are complementary and of a different nature. The blocking function is obtained by complementary serrated or toothed elements, which allow the installation on a gliding board of a shoe attachment device which withstands very great efforts, and is thus adapted to the practice of skiing. for example. The catch-up function of the games is generally provided by a member offering a simple support intended to reduce, and even to eliminate, the parasitic movements of the connecting element, in particular with respect to the slides according to the embodiment. In addition to these structural differences, a second difference is functional. The blocking, despite the presence of games, is enough to resist the constraints exerted by a skier for example. On the contrary, the catching up of the games would be totally insufficient and useless alone. By nature, it must be combined with a blocking element. Thus, according to the advantageous embodiment, the component (s) catch (s) games is / are distinct (s) of the locking element.

Comme mentionné précédemment, un mode de réalisation de l'invention pourrait être implémenté sur un surf des neiges (snowboard) pour le réglage de l'embase qui reçoit le dispositif de fixation d'une chaussure. Dans un tel cas, ce dispositif de fixation maintient toute la chaussure, et non pas seulement une partie avant ou arrière comme sur un ski, et l'embase est en général réglable dans la direction longitudinale et/ou transversale au surf.As mentioned above, an embodiment of the invention could be implemented on a snowboard for adjusting the base that receives the attachment device of a shoe. In such a case, this fastening device holds the entire boot, and not only a front or rear part as on a ski, and the base is generally adjustable in the longitudinal direction and / or transverse to the surf.
