Description

DISPOSITIF DE REGLAGE DE LA POSITION D' UNE FIXATION SUR UNE PLANCHE DE GLISSEDEVICE FOR ADJUSTING THE POSITION OF A FIXATION ON A SLIDING BOARD
Dispositif de réglage de la position d'une fixation sur une planche de glisse, en particulier de snowboard et planche de glisse adaptée à un tel dispositif .Device for adjusting the position of a binding on a gliding board, in particular a snowboard and gliding board suitable for such a device.
La présente invention concerne un dispositif de réglage de la position d'une fixation sur une planche de glisse. Elle se rapporte plus particulièrement à un dispositif adapté pour une planche du type 'Snowboard'.The present invention relates to a device for adjusting the position of a binding on a gliding board. It relates more particularly to a device suitable for a board of the 'Snowboard' type.
L'invention concerne aussi une planche de snowboard équipée selon le dispositif.The invention also relates to a snowboard fitted with the device.
La pratique du snowboard se fait à l'aide d'une planche allongée, dont l'extrémité avant, au moins, est relevée pour former la spatule. Les deux chaussures de l'utilisateur sont immobilisées sur la planche par des éléments de retenue adaptés. Les positions adoptées pour la pratique de ce sport sont très variables en fonction des disciplines pratiquées, du niveau ou des habitudes de l'utilisateur, ou encore en fonction de sa morphologie. Par exemple, pour la pratique de certaines disciplines orientées vers la recherche de la réalisation de figures, telle que le "free style" ou de la pratique "hors limite" telle que le "free ride", les pieds sont très écartés l'un de l'autre et sont très inclinés par rapport à l'axe longitudinal du snowboard dans une position sensiblement transversale, généralement non parallèles entre eux. Sur certaines planches totalement symétriques par rapport à l'axe transversal médian, les surfeurs adoptent une position de pieds dite en "canard" pour permettre la pratique indifféremment dans un sens ou dans un autre.Snowboarding is done using an elongated board, the front end of which, at least, is raised to form the tip. The user's two shoes are immobilized on the board by suitable retaining elements. The positions adopted for the practice of this sport are very variable depending on the disciplines practiced, the level or habits of the user, or according to his morphology. For example, for the practice of certain disciplines oriented towards the research of the realization of figures, such as "free style" or of practice "out of bounds" such as "free ride", the feet are very wide apart on the other and are very inclined relative to the longitudinal axis of the snowboard in a substantially transverse position, generally not parallel to each other. On certain boards which are completely symmetrical with respect to the median transverse axis, the surfers adopt a so-called "duck" position of the feet to allow the practice indifferently in one direction or another.
Au contraire, pour la pratique de disciplines de slalom ou de vitesse, les pieds sont moins écartés l'un de l'autre et se rapprochent, en inclinaison, de l'axe longitudinal médian.On the contrary, for the practice of slalom or speed disciplines, the feet are less spaced from each other and approach, in inclination, the median longitudinal axis.
Pour répondre à cette diversité de réglage, les systèmes actuels ne donnent pas entière satisfaction. L'un des plus répandu consiste à prévoir, sur le surf plusieurs rangées de trous filetés pour le passage de vis servant à immobiliser une platine généralement circulaire ; la platine maintenant elle-même une embase de fixation dans une position angulaire déterminée. Le brevet AT 1387/92 divulgue un système de réglage de ce type pour le support d'une fixation de snowboard. Selon ce dispositif, le choix des positions reste limité, notamment selon la direction longitudinale de la planche. De même, le réglage nécessite le recours à un outil tel qu'un tournevis et rend donc la manipulation longue et fastidieuse, et donc généralement impossible sur le terrain. Ces dispositifs ne sont pas non plus adaptés pour la location où la facilité et la rapidité du réglage sont prépondérantes.To respond to this diversity of adjustment, current systems are not entirely satisfactory. One of the most widespread consists of providing, on the surf, several rows of threaded holes for the passage of screws used to immobilize a generally circular plate; the plate itself maintaining a fixing base in a determined angular position. Patent AT 1387/92 discloses an adjustment system of this type for the support of a snowboard binding. According to this device, the choice of positions remains limited, in particular along the longitudinal direction of the board. Similarly, the adjustment requires the use of a tool such as a screwdriver and therefore makes handling long and tedious, and therefore generally impossible in the field. These devices are also not suitable for rental where the ease and speed of adjustment are paramount.
Un des buts de la présente invention est donc de proposer un dispositif de réglage de la position d'une fixation qui apporte réellement un large choix de possibilité de réglage en particulier en orientation angulaire et en position longitudinale tout en restant facilement et rapidement manoeuvrable sans disposer d'outils particuliers.One of the aims of the present invention is therefore to propose a device for adjusting the position of a binding which actually provides a wide choice of adjustment possibilities, in particular in angular orientation and in longitudinal position while remaining easily and quickly maneuverable without having special tools.
Un autre but de l'invention est de proposer un dispositif qui s'adapte, en particulier en snowboard, à la plupart des systèmes actuels d'embase de fixation qui utilise le standard usuel 4x4 en servant ainsi d'interface de réglage entre le snowboard et l'embase.Another object of the invention is to propose a device which adapts, in particular in snowboarding, to most of the current fixing base systems which uses the usual standard 4x4 thereby serving as an adjustment interface between the snowboard and the base.
La présente invention concerne aussi une planche de snowboard particulièrement adaptée pour recevoir le dispositif de réglage de position selon l'invention.The present invention also relates to a snowboard particularly suitable for receiving the position adjustment device according to the invention.
Un des buts est donc aussi de proposer une planche de snowboard avec dispositif de réglage intégré qui s'adapte à la plupart des systèmes actuels d'embase de fixation utilisés. En plus, la planche offre une plage d'ajustement continu en position longitudinale permettant d'obtenir une adaptation aux différentes disciplines pratiquées en snowboard.One of the goals is therefore also to offer a snowboard with integrated adjustment device which adapts to most of the current fixing base systems used. In addition, the board offers a range of continuous adjustment in the longitudinal position allowing to obtain an adaptation to the different disciplines practiced in snowboarding.
Un autre but de l'invention est aussi de proposer une planche de snowboard qui possède une grande résistance à l'arrachement des fixations dans les conditions d'utilisation les plus dures.Another object of the invention is also to propose a snowboard which has a high resistance to tearing of the bindings under the harshest conditions of use.
Pour répondre à ces objets ainsi qu'à d'autres, la présente invention se présente comme un dispositif de réglage de la position d'une fixation sur une planche de glisse destiné à coopérer dans une portion de rail ménagée dans la planche, caractérisé en ce qu'il comprend :To meet these and other objects, the present invention is presented as a device for adjusting the position of a binding on a gliding board intended to cooperate in a portion of rail formed in the board, characterized in what he understands:

- un moyen d'actionnement qui commande la tige centrale en translation pour modifier la position verticale relative de l'organe de coulissement à l'intérieur de la portion de rail ; entre une position libérée de la platine en rotation et en translation le long de la portion de rail et une position de serrage au cours de laquelle la surface inférieure de la platine comprime le moyen de friction contre la face supérieure de la planche.- An actuating means which controls the central rod in translation to modify the relative vertical position of the sliding member inside the rail portion; between a position freed from the plate in rotation and in translation along the portion rail and a clamping position during which the lower surface of the plate compresses the friction means against the upper face of the board.

Each device is intended to receive a binding for immobilizing a shoe (not shown). Different types of bindings can adapt to such a device for retaining rigid shell shoes or boots of the flexible type. It is therefore not in the spirit of the present invention to limit itself to the use of a particular type of fixing. In the mode shown, each device comprises a central plate 3 connected to the board by a particular mechanism which will be described later. A base 4 whose main function is to support the shoe retaining means is shown in dotted lines by way of example. The base is secured to the plate and is oriented along a main axis O forming an angle of inclination α relative to the longitudinal axis (M 1 ). One of the objects of the invention is to be able to vary the angle of inclination α, at will, by releasing the central plate 3 in rotation and by providing a rapid locking mechanism in the desired angular position.
La planche de snowboard comprend aussi deux portions de rails 5 disposés selon l'axe longitudinal (l-l1) et espacées l'une de l'autre. La longueur de chaque portion de rail et l'espacement entre eux sont des paramètres facilement déterminables par l'homme de l'art pour couvrir l'ensemble, ou tout au moins la plupart, des réglages usuels utilisés et recherchés par les utilisateurs. Un autre objet de l'invention est donc aussi de pouvoir faire varier la position longitudinale de la platine centrale 3 par rapport à la planche sur la longueur de portion de rail prévue, en même temps que le réglage angulaire est obtenu et sans manipulation supplémentaire.The snowboard also includes two portions of rails 5 arranged along the longitudinal axis (11 1 ) and spaced from one another. The length of each portion of rail and the spacing between them are parameters easily determinable by those skilled in the art to cover all, or at least most, of the usual adjustments used and sought by users. Another object of the invention is therefore also to be able to vary the longitudinal position of the central plate 3 with respect to the board over the length of the rail portion provided, at the same time as the angular adjustment is obtained and without additional manipulation.
Il est préférable de prévoir pour chaque dispositif, une portion de rail distincte et séparée de façon à influencer le moins possible la libre flexion de la planche. En revanche, on peut envisager que chaque portion ne soit pas orientée strictement selon l'axe (l-l') mais au contraire soit légèrement décalée et parallèle, ou inclinée par rapport à celui-ci.It is preferable to provide for each device, a separate and separate rail portion so as to influence as little as possible the free bending of the board. On the other hand, it can be envisaged that each portion is not oriented strictly along the axis (l-l ') but on the contrary is slightly offset and parallel, or inclined relative to the latter.
Selon le premier mode des figures 2 à 4, le dispositif de réglage 2 comprend une platine centrale 3 en forme de disque, munie d'une surface inférieure 30 en contact avec un moyen de friction 22 ; lui-même en contact avec la surface supérieure 10 de la planche. Un organe de coulissement 20 est logé à l'intérieur de la portion de rail 5 et est relié à la platine centrale par une tige centrale 21 solidaire fixement de l'organe de coulissement 20. La platine centrale 3 est munie d'une surface supérieure de réception 31 destinée à recevoir une embase de fixation (non représentée), d'un logement central 32 ; et à l'intérieur de celui-ci d'un alésage central 33 pour le passage de la tige centrale 21. La tige centrale 21 est montée libre en translation verticale dans l'alésage 33 de la platine.According to the first mode of Figures 2 to 4, the adjustment device 2 comprises a central plate 3 in the form of a disc, provided with a lower surface 30 in contact with a friction means 22; itself in contact with the upper surface 10 of the board. A sliding member 20 is housed inside the rail portion 5 and is connected to the central plate by a central rod 21 fixedly secured to the sliding member 20. The central plate 3 is provided with an upper surface reception 31 intended to receive a fixing base (not shown), of a central housing 32; and inside of it a central bore 33 for the passage of the central rod 21. The central rod 21 is mounted free in vertical translation in the bore 33 of the plate.
Un moyen d'actionnement 23 commande la tige centrale 21 en translation verticale. La tige centrale 21 comprend une portion filetée 212 sur laquelle est vissé un moyen de réglage fileté 232 tel qu'un simple écrou par exemple. Une rondelle 233 est disposée entre le moyen de réglage 232 et la platine. Le moyen d'actionnement comprend un organe d'excentrique à came 230 monté pivotant sur le moyen de réglage fileté 232 par deux goupilles radiales 234.An actuating means 23 controls the central rod 21 in vertical translation. The central rod 21 includes a threaded portion 212 onto which is screwed a threaded adjustment means 232 such as a simple nut for example. A washer 233 is disposed between the adjusting means 232 and the plate. The actuating means comprises a cam eccentric member 230 pivotally mounted on the threaded adjusting means 232 by two radial pins 234.
Dans ce mode, l'organe excentrique à came est relié indirectement à la tige centrale par une liaison pivot et actionnable manuellement au moyen d'un levier 231 solidaire de l'organe pour déplacer la tige 21 en translation axiale à travers l'alésage 33, vers le haut pour atteindre la position de serrage et inversement, vers le bas pour atteindre la position libérée.In this mode, the cam eccentric member is indirectly connected to the central rod by a pivot link and manually operable by means of a lever 231 secured to the member to move the rod 21 in axial translation through the bore 33 , upwards to reach the clamping position and vice versa, downwards to reach the released position.
Le moyen de réglage fileté 232 a pour fonction de permettre d'ajuster l'effort de serrage dans la position de serrage de la platine.The threaded adjusting means 232 has the function of making it possible to adjust the clamping force in the clamping position of the plate.
Le logement central 32 a une profondeur suffisante par rapport à la surface 31 pour contenir le moyen d'actionnement 23 sans dépassement du levier 231 lorsque celui-ci se trouve en position escamotée correspondant à la position de serrage de la platine.The central housing 32 has a sufficient depth relative to the surface 31 to contain the actuating means 23 without exceeding the lever 231 when the latter is in the retracted position corresponding to the clamping position of the plate.
Le fonctionnement du dispositif est le suivant en position déverrouillée, représentée à la figure 5, le levier 231 est relevé, de sorte que l'organe d'excentrique à came qui lui est solidaire, se trouve dégagé de la surface de la platine centrale 3. La platine étant montée par une liaison pivot glissant sur la tige 21 peut alors être orientée dans la position angulaire désirée. De même, sans effort de serrage, l'organe de coulissement, ou coulisseau 20, est libéré en translation dans la portion de rail, permettant aussi de déplacer l'ensemble du dispositif dans le sens choisi A ou B.The device operates as follows in the unlocked position, shown in FIG. 5, the lever 231 is raised, so that the cam eccentric member which is integral with it, is released from the surface of the central plate 3 The plate being mounted by a pivoting link sliding on the rod 21 can then be oriented in the desired angular position. Similarly, without clamping force, the sliding member, or slide 20, is released in translation in the rail portion, also making it possible to move the entire device in the chosen direction A or B.
La position verrouillée de la figure 6 est obtenue en abaissant le levier 231 dans sa position escamotée. Celui-ci entraîne en rotation l'organe d'excentrique 230 qui prend appui sur la platine centrale 3 ; ce qui déplace la tige centrale 21 vers le haut et contraint le coulisseau 20 à remonter dans la portion de rail. En position de serrage, l'organe d'excentrique exerce un effort de traction sur la tige et donc sur le coulisseau, en s'appuyant sur la platine qui comprime le moyen de friction 22 sur la surface de la planche. Dans cette configuration, le déplacement longitudinal du coulisseau dans ie rail et le déplacement angulaire de la platine ne sont plus permis. Le serrage peut être contrôlé par le moyen de réglage fileté 232 avant d'abaisser le levier. En vissant, on rapproche la came de l'organe d'excentrique de la surface de la platine le long de la tige centrale, et on augmente donc le serrage. Les figures 7 et 8 illustrent un second mode de réalisation de l'invention. Le seul changement important par rapport au mode précédent provient du moyen d'actionnement 23 qui est différent.The locked position of Figure 6 is obtained by lowering the lever 231 into its retracted position. The latter rotates the eccentric member 230 which bears on the central plate 3; which moves the central rod 21 upwards and forces the slide 20 to go up in the rail portion. In the clamping position, the eccentric member exerts a tensile force on the rod and therefore on the slide, by pressing on the plate which compresses the friction means 22 on the surface of the board. In this configuration, the longitudinal movement of the slide in the rail and the angular movement of the plate are no longer allowed. The tightening can be controlled by the threaded adjusting means 232 before lowering the lever. By screwing, the cam is brought closer to the eccentric member of the surface of the plate along the central rod, and therefore the tightening is increased. Figures 7 and 8 illustrate a second embodiment of the invention. The only significant change compared to the previous mode comes from the actuation means 23 which is different.
On retrouve une platine centrale 3 en forme de disque en contact avec un moyen de friction 22. Un organe de coulissement 20 est logé à l'intérieur de la portion de rail 5 et est relié à une tige centrale 21 de manière solidaire. La tige centrale traverse l'alésage central 33 de la platine. Elle est montée libre en translation axiale par rapport à la platine par une liaison glissière. Pour permettre une transmission du mouvement vertical, la tige est bloquée en rotation par un méplat 211.There is a central plate 3 in the form of a disc in contact with a friction means 22. A sliding member 20 is housed inside the rail portion 5 and is connected to a central rod 21 integrally. The central rod passes through the central bore 33 of the plate. It is mounted free in axial translation relative to the plate by a slide link. To allow transmission of the vertical movement, the rod is locked in rotation by a flat 211.
Le moyen d'actionnement 23 présente un levier 231 qui commande en rotation un organe à rampe annulaire 234 monté par une liaison pivot glissant par rapport à la tige centrale 21 et qui agit sur un ou plusieurs ergots radiaux 210 de la tige centrale pour déplacer celle-ci en translation axiale vers le haut pour atteindre la position de serrage et, inversement vers le bas, pour atteindre la position libérée.The actuating means 23 has a lever 231 which rotates an annular ramp member 234 mounted by a pivoting link sliding relative to the central rod 21 and which acts on one or more radial lugs 210 of the central rod to move that -ci in axial translation upwards to reach the clamping position and, conversely downwards, to reach the released position.
Comme le montre la figure 8, la tige centrale est munie de deux ergots 210 radialement opposés. L'organe à rampe annulaire présente, quant à lui, deux surfaces de rampe 234a pour le guidage des ergots et qui présentent chacune une pente progressive se terminant en position haute par un creux radial 234b pour le blocage de chaque ergot en position de serrage de la platine.As shown in Figure 8, the central rod is provided with two radially opposite lugs 210. The annular ramp member has two ramp surfaces 234a for guiding the pins and which each have a progressive slope ending in the high position with a radial recess 234b for locking each lug in the clamping position of platinum.
Comme dans le mode précédent, la platine centrale 3 présente une surface supérieure de réception 31 et un logement central 32 de profondeur suffisante par rapport à la surface supérieure, pour contenir l'organe à rampe annulaire sans dépassement, ni de celui-ci, ni de l'extrémité de la tige centrale par rapport à la surface supérieure de réception 31 lorsque la position haute de blocage est atteinte.As in the previous mode, the central plate 3 has an upper receiving surface 31 and a central housing 32 of sufficient depth relative to the upper surface, to contain the annular ramp member without protruding either from it or from the end of the central rod relative to the upper receiving surface 31 when the high blocking position is reached.
Le dispositif comprend un second logement 34 ménagé sous la platine, en retrait par rapport à la surface inférieure 30 de la platine en contact avec le moyen de friction, qui communique avec le logement central 32 d'une part et qui est débouchant par une ouverture 34a sur le côté de la platine d'autre part. Le levier, quant à lui, est muni d'un bras 231a qui relie l'organe à rampe annulaire 234 à travers ledit logement et qui se prolonge hors de l'ouverture 34a par une manette 231 b actionnable en rotation.The device comprises a second housing 34 formed under the plate, set back with respect to the lower surface 30 of the plate in contact with the friction means, which communicates with the central housing 32 on the one hand and which opens out through an opening 34a on the side of the plate on the other hand. The lever, meanwhile, is provided with an arm 231a which connects the annular ramp member 234 through said housing and which extends out of the opening 34a by a lever 231 b actuable in rotation.
Le dispositif n'étant pas réglable, on prévoit un moyen élastique, telle qu'une ou plusieurs rondelle(s) Belleville 24, logé dans la portion de rail et qui oppose une résistance élastique à la compression pour maintenir l'organe de coulissement en pression. Plus précisément, la rondelle 'Belleville' est simplement montée à travers la tige centrale et logée entre le coulisseau 20 et une rondelle d'appui 25 dont la largeur est choisie supérieure à l'ouverture 50 du rail.Since the device is not adjustable, an elastic means is provided, such as one or more Belleville washer (s) 24, housed in the rail portion and which offers an elastic resistance to compression for keep the sliding member under pressure. More specifically, the 'Belleville' washer is simply mounted through the central rod and housed between the slide 20 and a support washer 25 whose width is chosen greater than the opening 50 of the rail.
Le passage de serrage du dispositif à la position libérée, et inversement, se fait simplement en actionnant la manette 231 b du levier par une rotation d'un quart de tour environ.The clamping passage of the device to the released position, and vice versa, is done simply by actuating the lever 231 b of the lever by a rotation of about a quarter of a turn.
Les figures 9 et 10 détaillent une autre variante de l'invention avec un levier d'actionnement décalé par rapport à la platine ; ce qui a pour avantage de permettre un réglage sans devoir dégager la chaussure des moyens de retenue solidaires directement ou indirectement de la platine.Figures 9 and 10 detail another variant of the invention with an actuating lever offset from the plate; which has the advantage of allowing adjustment without having to disengage the shoe from the retaining means directly or indirectly attached to the plate.
Le dispositif possède un moyen d'actionnement 23 qui comprend un élément de transmission 235 logé, en partie au moins, dans la portion de rail 5. L'élément est relié à la tige centrale 21 par une liaison pivot glissante. Il présente une première portion allongée 235a qui se termine par un moyen d'appui 236 décalé d'une certaine distance d1 par rapport à l'axe de la tige centrale. Le moyen d'appui 236 se présente sous la forme d'une partie cylindrique de largeur supérieure à l'ouverture 40 du rail. Le moyen d'actionnement présente une seconde portion allongée 235b qui se prolonge du côté opposé à la première portion, et est reliée par un organe de serrage décalé 237, situé à une distance d2 de l'axe de la tige. La distance d1 de la première portion 235a est inférieure à la distance d2 de la seconde portion 235b, de telle sorte que l'action de serrage de l'organe de serrage décalé 237 provoque un effet de levier qui déplace la tige centrale 21 en translation axiale vers le bas jusqu'à la position de serrage de la platine.The device has an actuating means 23 which comprises a transmission element 235 housed, at least in part, in the rail portion 5. The element is connected to the central rod 21 by a sliding pivot connection. It has a first elongated portion 235a which ends with a support means 236 offset by a certain distance d1 relative to the axis of the central rod. The support means 236 is in the form of a cylindrical part of width greater than the opening 40 of the rail. The actuating means has a second elongated portion 235b which extends on the side opposite to the first portion, and is connected by an offset clamping member 237, located at a distance d2 from the axis of the rod. The distance d1 of the first portion 235a is less than the distance d2 of the second portion 235b, so that the clamping action of the offset clamping member 237 causes a lever effect which displaces the central rod 21 in translation axial down to the clamping position of the plate.
Pour améliorer l'effet de levier engendré, l'élément de transmission 235 comprend, entre les deux portions allongées 235a, 235b, un disque d'appui 235c, au travers duquel passe la tige centrale. Le disque 235c prend appui contre l'organe de coulissement 20 pour le repousser vers le bas, par effet de levier engendré lors de l'action de serrage du moyen de serrage décalé 237.To improve the leverage generated, the transmission element 235 comprises, between the two elongated portions 235a, 235b, a support disc 235c, through which the central rod passes. The disc 235c bears against the sliding member 20 to push it down, by lever effect generated during the clamping action of the offset clamping means 237.
Le moyen de serrage décalé 237 comprend :The offset clamping means 237 comprises:
- un second organe de coulissement ou coulisseau 237a logé à l'intérieur de la portion de rail ;- A second sliding member or slide 237a housed inside the rail portion;
- une tige 237b fixée à l'organe de coulissement 237a et se prolongeant en dehors du rail et au travers de la seconde portion allongée 235b, de façon libre en translation ; - un organe d'excentrique à came 237c relié à la tige par une liaison pivot et actionnable au moyen d'un levier 237d solidaire dudit organe pour déplacer la tige en translation axiale vers le haut pour atteindre la position de serrage, et inversement, vers le bas pour atteindre la position libérée.- A rod 237b fixed to the sliding member 237a and extending outside the rail and through the second elongated portion 235b, in free translation; - a cam eccentric member 237c connected to the rod by a pivot link and actuable by means of a lever 237d secured to said member to move the rod in axial translation upward to reach the clamping position, and vice versa, towards down to reach the released position.
La tige 237b est munie d'une portion filetée sur laquelle est vissée un moyen de réglage fileté 237e. L'organe d'excentrique 237c est monté pivotant directement sur le moyen de réglage fileté au moyen de deux goupilles radiales 237f.The rod 237b is provided with a threaded portion on which is screwed a threaded adjustment means 237e. The eccentric member 237c is pivotally mounted directly on the threaded adjustment means by means of two radial pins 237f.
Le moyen de réglage 237e peut être un écrou à six pans par exemple. Il a pour fonction de permettre l'ajustement de l'effort de serrage du moyen de serrage 237.The adjusting means 237e can be a hexagon nut for example. Its function is to allow the adjustment of the clamping force of the clamping means 237.
La tige centrale 21 du dispositif est munie aussi d'une portion supérieure filetée 212a. Elle est bloquée en translation par rapport à ia platine par un élément fileté réglable 212b, du type écrou par exemple. Cet élément permet un rattrapage de jeu du dispositif. L'élément fileté prend place dans un logement central 32 suffisamment large pour pouvoir le manipuler au moyen d'un outil tel qu'une clef.The central rod 21 of the device is also provided with a threaded upper portion 212a. It is blocked in translation relative to the plate by an adjustable threaded element 212b, of the nut type for example. This element allows a backlash of the device. The threaded element takes place in a central housing 32 sufficiently wide to be able to handle it by means of a tool such as a key.
Le principe de fonctionnement est illustré par les figures schématiques 11 et 12.The operating principle is illustrated by schematic figures 11 and 12.
La figure 1 1 montre le dispositif dans une configuration de verrouillage. Le levier 237d de l'organe de serrage décalé 237 est en position escamotée ; ce qui a pour effet de placer la came de l'organe d'excentrique 237c en position d'appui sur l'extrémité de la seconde partie allongée 235b, qui de ce fait se déplace vers le bas et se rapproche de l'organe de coulissement 237a qui se déplace lui vers le haut par entraînement en translation de la tige 237b. L'appui exercé vers le bas sur l'extrémité de la seconde portion allongée se transmet en un appui vers le haut de l'extrémité d'appui 236 et en un effort plus important de traction du à l'effet de levier sur la tige centrale qui tend à rapprocher la platine de la surface de la planche et à comprimer le moyen de friction 22.Figure 1 1 shows the device in a locking configuration. The lever 237d of the offset clamping member 237 is in the retracted position; which has the effect of placing the cam of the eccentric member 237c in the support position on the end of the second elongated portion 235b, which therefore moves downwards and approaches the member sliding 237a which moves it upwards by translational driving of the rod 237b. The downward support on the end of the second elongated portion is transmitted by an upward support from the support end 236 and by a greater traction force due to the leverage on the rod central which tends to bring the plate closer to the surface of the board and to compress the friction means 22.
En position de déverrouillage, le levier est en position haute ; de sorte que la came de l'organe d'excentrique 237c n'applique plus d'effort de serrage à l'extrémité de la seconde portion allongée 235b. De ce fait, l'effort en traction vers le bas exercé sur le coulisseau disparaît ce qui libère le dispositif en translation, et la platine qui n'exerce plus de compression sur ie moyen de friction est libérée, quant à elle, en rotation. L'ensemble du dispositif y compris l'organe de serrage décalé peut être déplacé en translation dans la portion de rail dans la direction voulue A ou B.In the unlocked position, the lever is in the high position; so that the cam of the eccentric member 237c no longer applies a clamping force to the end of the second elongated portion 235b. Therefore, the downward traction force exerted on the slide disappears which frees the device in translation, and the plate which no longer exerts compression on the friction means is released, in turn, in rotation. The entire device including the offset clamping member can be moved in translation in the rail portion in the desired direction A or B.
Dans tous les modes représentés, le moyen de friction joue un rôle important puisqu'il a pour fonction de créer entre la surface inférieure de la platine et la surface supérieure de la planche, une interface qui lorsqu'elle est soumise à un effort de compression, participe à l'immobilisation de la platine en rotation par effet de friction.In all the modes shown, the friction means plays an important role since it has the function of creating between the lower surface of the plate and the upper surface of the board, an interface which when it is subjected to a compressive force , participates in the immobilization of the plate in rotation by friction effect.
Un tel moyen peut être constitué d'un disque en matériau choisi parmi ceux possédant des propriétés de compressibilité et d'élasticité importantes. Parmi ies matériaux susceptibles de convenir ; on peut citer tout particulièrement les caoutchoucs naturels et artificiels, certains plastiques, le liège et le feutre. Bien entendu, le disque constituant le moyen de friction peut être collé ou vissé sur la surface inférieure de la platine ou sur la surface supérieure de la planche afin de faciliter le déplacement du dispositif dans la portion de rail.Such a means can consist of a disc of material chosen from those having significant compressibility and elasticity properties. Among the materials likely to be suitable; mention may be made in particular of natural and artificial rubbers, certain plastics, cork and felt. Of course, the disc constituting the friction means can be glued or screwed on the lower surface of the plate or on the upper surface of the board in order to facilitate the movement of the device in the rail portion.
Dans les exemples illustrés, la platine a la forme d'un disque muni d'au moins quatre trous filetés 3a, 3b, 3c, 3d formant un quadrilatère pour la réception d'une embase de fixation adaptée (figure 3 et 4).In the examples illustrated, the plate has the shape of a disc provided with at least four threaded holes 3a, 3b, 3c, 3d forming a quadrilateral for the reception of a suitable fixing base (FIGS. 3 and 4).
De préférence, les trous sont séparés deux à deux d'une distance de 4 cm pour répondre au standard usuel du snowboard.Preferably, the holes are separated two by two by a distance of 4 cm to meet the usual standard of snowboarding.
Bien entendu, la platine peut prendre d'autres formes que celle d'un disque. Par exemple, il peut s'agir d'une plaque allongée de forme sensiblement identique à la semelle d'une chaussure pour la réception directe d'une fixation de snowboard du type 'coque' ou autre.Of course, the turntable can take other forms than that of a disc. For example, it may be an elongated plate of substantially identical shape to the sole of a shoe for the direct reception of a snowboard binding of the 'shell' type or the like.
Comme le montre la figure 13, chaque portion de rail est constituée d'un élément profilé 6 ayant un profil transversal sensiblement rectangulaire.As shown in Figure 13, each rail portion consists of a profiled element 6 having a substantially rectangular transverse profile.
Il comprend un canal 60 délimité par une paroi de fond 61 , deux parois latérales 62, 63 reliées à la paroi de fond et deux bords supérieurs 64, 65 qui s'opposent pour former une ouverture 66 de largeur I inférieure à la plus grande largeur L du canal. Au lieu d'une forme rectangulaire, le profil peut être choisi trapézoïdal, par exemple. L'élément profilé comprend aussi des bords latéraux d'ancrage 67, 68 qui prolongent la paroi de fond et s'étendent vers l'extérieur, afin d'améliorer la résistance de l'ancrage dans la structure de la planche.It comprises a channel 60 delimited by a bottom wall 61, two side walls 62, 63 connected to the bottom wall and two upper edges 64, 65 which oppose to form an opening 66 of width I less than the greatest width L of the canal. Instead of a rectangular shape, the profile can be chosen trapezoidal, for example. The profiled element also comprises lateral anchoring edges 67, 68 which extend the bottom wall and extend outwards, in order to improve the resistance of the anchoring in the structure of the board.
Bien entendu, la présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisation contenues dans le domaine des revendications ci-après. Of course, the present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalization thereof contained in the field of claims below.
