Abstract
Description
L'invention se rapporte à un dispositif de serrage à cliquet utilisé sur des vêtements ou des articles de sport.The invention relates to a ratchet clamping device used on clothing or sports articles.
De tels dispositifs servent à tendre de façon réversible des éléments tels que des rabats de chaussure, des pièces de tissus, ou autre.Such devices serve to reversibly tension elements such as shoe flaps, pieces of fabric, or the like.
Un exemple d'application est donné pour le domaine du surf sur neige, ou snowboard. Certaines fixations de snowboard comprennent un ou plusieurs liens pour retenir de façon amovible une botte sur une embase de la fixation.An example of application is given for the field of snowboarding, or snowboarding. Some snowboard bindings include one or more links for removably retaining a boot on a base of the binding.
Un lien comprend généralement une bande, un capot, et un dispositif de serrage à cliquet solidarisé au capot. La longueur du lien est ajustée en déplaçant la bande par rapport au capot à l'aide du dispositif. Pour ce faire, un levier du dispositif permet de raccourcir le lien, le cliquet empêchant un allongement quand le levier n'agit pas. En cas de nécessité l'allongement du lien, ou son ouverture par séparation de la bande et du capot, est obtenu en agissant sur le cliquet à l'aide d'un bouton de libération. Cette opération est un acte voulu par un utilisateur du dispositif, c'est-à-dire par une personne qui pratique le snowboard et qui veut soit réduire la tension du lien, soit libérer une botte d'une fixation.A link generally comprises a strip, a cover, and a ratchet clamping device secured to the cover. The length of the link is adjusted by moving the band relative to the hood using the device. To do this, a lever of the device can shorten the link, the ratchet preventing elongation when the lever does not act. If necessary the lengthening of the link, or its opening by separation of the band and the cover, is obtained by acting on the pawl with a release button. This operation is an act desired by a user of the device, that is to say by a person who practices snowboarding and who wants to either reduce the tension of the link, or release a boot of a binding.
Cependant il est apparu que, dans certaines circonstances, un allongement ou une ouverture non souhaitée du lien se produit. Cela signifie que contre son gré, l'utilisateur n'a plus le pied suffisamment serré ou retenu à la planche.However, it has become apparent that in some circumstances undesired extension or opening of the link occurs. This means that against his will, the user no longer has the foot sufficiently tight or restrained to the board.
Un exemple particulier est donné par le document US 5,745,959. Selon ce document, un dispositif de serrage à cliquet est muni d'un levier qui permet de raccourcir un lien. Un ou plusieurs boutons sont disposés en saillie sur le levier, pour qu'un utilisateur puisse manipuler celui-ci avec des gants. Le corollaire de cette structure est qu'une ouverture intempestive est possible.A particular example is given by US 5,745,959. According to this document, a ratchet clamping device is provided with a lever that makes it possible to shorten a link. One or more buttons are protruding on the lever, so that a user can handle it with gloves. The corollary of this structure is that untimely opening is possible.
L'un des buts de l'invention est d'éviter un déplacement non voulu d'une bande par rapport à un dispositif à cliquet.One of the aims of the invention is to avoid an unwanted displacement of a band with respect to a ratchet device.
Pour ce faire, l'invention propose un dispositif de serrage d'une bande comprenant une embase, un levier d'entraînement, un cliquet, et un bouton de libération, l'embase présentant un premier flasque et un deuxième flasque reliés par un pont, le levier étant articulé sur l'embase entre les flasques, le levier comprenant d'une part une extrémité prévue pour entraîner la bande selon une première direction sensiblement parallèle aux flasques et au pont, et d'autre part une extrémité de manutention, le cliquet étant articulé sur l'embase entre les flasques, le cliquet présentant une zone de retenue prévue pour s'opposer au déplacement de la bande selon une deuxième direction inverse à la première direction, un moyen élastique sollicitant en permanence la zone de retenue du cliquet vers le pont, le bouton de libération étant prévu pour éloigner la zone de retenue du cliquet par rapport au pont contre l'action du moyen élastique.To do this, the invention proposes a clamping device for a band comprising a base, a drive lever, a pawl, and a release button, the base having a first flange and a second flange connected by a bridge. , the lever being articulated on the base between the flanges, the lever comprising on the one hand an end intended to drive the strip in a first direction substantially parallel to the flanges and to the bridge, and on the other hand a handling end, the ratchet being articulated on the base between the flanges, the ratchet having a zone of retainer designed to oppose the displacement of the strip in a second direction opposite to the first direction, a resilient means permanently urging the retaining zone of the pawl towards the bridge, the release button being provided to move the retaining zone away from the ratchet relative to the bridge against the action of the elastic means.
Le dispositif de serrage selon l'invention est caractérisé par le fait que le bouton est sensiblement escamoté par rapport au levier ou au moins par rapport aux flasques, dans une direction sensiblement perpendiculaire au pont, quand le levier est dans une position de repos qui permet la retenue de la bande, position dans laquelle l'extrémité de manutention est la plus proche du pont.The clamping device according to the invention is characterized in that the button is substantially retracted relative to the lever or at least relative to the flanges, in a direction substantially perpendicular to the bridge, when the lever is in a rest position which allows retaining the band, position in which the handling end is closest to the bridge.
Ainsi, l'appui ou le choc d'un objet sur le dispositif a très peu de chances d'induire un mouvement du cliquet, et par suite un déplacement de la bande.Thus, the support or the shock of an object on the device is very unlikely to induce a movement of the pawl, and consequently a displacement of the band.
Dans le cas de la fixation de snowboard, un appui ou un choc sur le dispositif a peu de chances d'induire un allongement ou une ouverture du lien.In the case of snowboard binding, a support or shock on the device is unlikely to induce an elongation or opening of the link.
D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, par un exemple non limitatif, comment l'invention peut être réalisée, et dans lequel :
- la figure 1 est une vue en perspective d'une fixation de snowboard munie d'un dispositif de serrage selon l'invention,
- la figure 2 est une vue de côté du dispositif,
- la figure 3 est une coupe schématique du dispositif selon III-III de la figure 1,
- la figure 4 est une coupe similaire à la figure 3, dans un cas où le dispositif entraîne une bande,
- la figure 5 est une coupe similaire à la figure 3, dans un cas où le dispositif libère la bande,
- la figure 6 est un agrandissement partiel de la figure 1 qui montre mieux le dispositif, dans un cas où ce dernier retient la bande.
- FIG. 1 is a perspective view of a snowboard binding provided with a clamping device according to the invention,
- FIG. 2 is a side view of the device,
- FIG. 3 is a schematic section of the device according to III-III of FIG. 1,
- FIG. 4 is a section similar to FIG. 3, in a case where the device causes a band,
- FIG. 5 is a section similar to FIG. 3, in a case where the device releases the strip,
- Figure 6 is a partial enlargement of Figure 1 which shows the device better, in a case where it retains the band.
Selon l'exemple choisi tel que montré à la figure 1, une fixation 1 retient une botte 2 sur une planche de snowboard 3.According to the example chosen as shown in FIG. 1, a binding 1 holds a
De manière connue, la fixation 1 présente une platine 4, ainsi qu'un premier bord latéral 5 et un deuxième bord latéral 6 reliés l'un à l'autre par un arceau 7.In known manner, the
La platine 4 s'étend selon une direction longitudinale L de la fixation entre une extrémité avant 8 et une extrémité arrière 9.The
Un lien 10 est prévu pour retenir de façon amovible la botte 2 sur la fixation 1.A
De façon non limitative, le lien 10 comprend par exemple un capot 11, une bande 12, et un dispositif de serrage 13 de la bande.Without limitation, the
Le capot 11, réalisé par exemple avec une ou plusieurs couches de matière souple, présente un point d'attache avant 14 et un point d'attache arrière 15 sur le premier bord latéral 5.The
La bande 12 est attachée sur le deuxième bord latéral 6.The
Les attaches du capot 11 et de la bande 12 sont réalisées par tout moyen convenable, telle qu'une articulation.The fasteners of the
La structure et le fonctionnement du dispositif 13 sont expliqués ci-après à l'aide des figures 2 à 6.The structure and operation of the
Le dispositif de serrage 13 est vu de côté sur la figure 2. Il comprend une embase 16 en forme du U prévue pour guider la bande 12. L'embase 16 comprend un premier flasque 17 et un deuxième flasque 18 reliés par un pont 19.The
L'embase 16 est solidarisée au capot 11 par exemple à l'aide d'un rivet d'axe 20.The
La bande 12 est quant à elle réalisée sous la forme d'une crémaillère, faite de préférence à partir d'une matière plastique. Les dents 21 et l'âme 22 de la bande 12 forment de préférence une pièce monobloc.The
Comme le montre la figure 3, le dispositif de serrage 13 comprend un cliquet 23 articulé selon un axe 24 entre les flasques 17, 18. Un moyen élastique non représenté, tel qu'un ressort, sollicite en permanence le cliquet 23 de façon qu'une zone de retenue 25 du cliquet soit poussée vers le pont 19. La zone de retenue 25 est représentée sous la forme d'une dent.As shown in Figure 3, the
Un levier d'entraînement 26 comprend d'une part une extrémité de manutention 27, et d'autre part une extrémité d'entraînement 28 munie d'au moins une dent 29.A
Un bouton de libération 30 présente une surface de came 31 prévue pour appuyer sur une surface de came 32 du cliquet 23, et une extrémité de manutention 33 prévue pour être actionnée à la main.A
Le levier d'entraînement 26 et le bouton de libération 30 sont articulés sur un même axe 34, entre les flasques 17, 18. Un moyen élastique non représenté, tel qu'un ressort, sollicite en permanence le levier 26 de façon que l'extrémité de manutention 27 soit poussée vers le pont 19.The
Ainsi en l'absence de toute sollicitation extérieure, les pièces constitutives du dispositif de serrage 13 occupent chacun la position comme il est montré sur la figure 3.Thus, in the absence of any external stress, the constituent parts of the
Comme la bande 12 est présente le long du pont 19 entre les flasques 17, 18, c'est-à-dire dans l'embase 16, le cliquet 23 s'oppose à un allongement du lien 10. Cela signifie qu'une extrémité 35 de la bande 12 ne peut se déplacer, dans un sens qui va d'une arête interne 36 vers une arête externe 37 de l'embase 16.As the
Un déplacement dans le sens inverse est par contre possible. Ce déplacement peut être provoqué par l'utilisateur comme c'est le cas à la figure 4.On the other hand, a movement in the opposite direction is possible. This displacement can be caused by the user as is the case in FIG.
Le levier d'entraînement 26 est actionné, à l'aide de l'extrémité 27, de façon que les dents 29 entraînent la bande 12. Dans ce cas l'extrémité 35 de la bande 12 se déplace dans un sens qui va de l'arête externe 37 vers l'arête interne 36. Cela signifie que le lien 10 devient plus court. Le serrage de la botte devient plus fort.The
A l'inverse si l'utilisateur veut desserrer le lien, ou même libérer la botte en ouvrant le lien, il lui suffit de procéder comme il est montré à la figure 5.Conversely, if the user wants to loosen the link, or even release the boot by opening the link, it suffices to proceed as shown in Figure 5.
Dans ce cas le levier d'entraînement 26 n'est pas sollicité, son extrémité de manutention 27 occupant la position la plus proche du pont 19. L'utilisateur agit, par exemple avec un doigt, sur l'extrémité de manutention 33 du bouton de libération 30.In this case the
La surface de came 31 du bouton 30 appuie sur la surface de came 32 du cliquet 23, de façon que la zone de retenue 25 du cliquet 23 s'éloigne du pont 19 et de la bande 12. Le lien 10 peut s'allonger, car le cliquet 23 ne retient plus la bande 12.The
Bien entendu, dès que l'action du bouton 30 cesse, le cliquet 23 reprend une position de retenue.Of course, as soon as the action of the
Un avantage, induit par la structure du dispositif de serrage 13, est que l'action manuelle sur le bouton de libération 30 tend à allonger et à ouvrir le lien 10One advantage, induced by the structure of the
Selon l'invention comme on le voit mieux sur la figure 6, le levier d'entraînement 26 présente une première aile 38 et une deuxième aile 39 par rapport auxquelles le bouton de libération 30 est escamoté, dans une direction sensiblement perpendiculaire à la bande 12. Chaque aile 38, 39 est située en position latérale par rapport au levier 26. Le bouton de libération 30 est logé entre les ailes 38, 39 du levier d'entraînement 26.According to the invention as best seen in Figure 6, the
Cette architecture est particulièrement intéressante si le dispositif de serrage est situé entre les pieds de l'utilisateur. Cela revient à dire que le premier bord latéral 5 de la fixation 1 est un bord extérieur, et que le deuxième bord latéral 6 est un bord intérieur.This architecture is particularly interesting if the clamping device is located between the feet of the user. That is to say that the first
Lorsque l'utilisateur a un seul pied retenu à la planche 3, et qu'il pousse en pas alternatif avec l'autre pied, il est fréquent qu'une botte en mouvement vienne heurter le dispositif de serrage de la fixation de l'autre botte encore retenue. Comme le bouton de libération 30 est escamoté, il n'est pas actionné par la botte en mouvement si celle-ci heurte le dispositif de serrage.When the user has only one foot retained in the
Il s'ensuit que le bouton de libération 30 n'est pas actionné contre la volonté de l'utilisateur.It follows that the
Cependant ce dernier peut facilement desserrer le lien 10. Il lui suffit pour cela d'agir sur l'extrémité de manutention 33 du bouton de libération 30, par exemple avec un doigt, dans un sens de rapprochement de l'extrémité libre 35 de la bande 12.However, the latter can easily loosen the
D'une manière générale les éléments constitutifs du lien 10, notamment ceux du dispositif de serrage 13, sont fabriqués avec des matériaux et selon des techniques connus de l'homme du métier.In general, the constituent elements of the
Bien entendu, l'invention n'est pas limitée à l'exemple ci-avant décrit, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Of course, the invention is not limited to the example described above, and includes all the technical equivalents may fall within the scope of the claims that follow.
Par exemple, le levier d'entraînement 26 et le bouton de libération 30 pourraient avoir d'autres formes.For example, the
Le levier d'entraînement pourrait comporter une seule aile.The drive lever could have a single wing.
Le bouton de libération 30 pourrait être escamoté par au moins l'un des flasques de l'embase. Dans ce cas, le flasque passe soit à travers une ouverture du levier d'entraînement, soit à côté du levier. Une pièce supplémentaire peut être ajoutée au dispositif de serrage pour permettre l'escamotage du bouton de libération 30.The
D'autre part, la structure interne du dispositif de serrage pourrait être différente. Par exemple, le cliquet et le bouton de libération pourraient former une pièce monobloc articulée sur un axe, et non pas deux pièces distinctes.On the other hand, the internal structure of the clamping device could be different. For example, the pawl and the release button could form a one-piece piece articulated on an axis, and not two separate parts.
Encore, bien que l'exemple de dispositif de serrage ait été décrit pour une application dans le domaine d'une fixation de snowboard, il peut être prévu d'utiliser le dispositif dans un autre domaine technique tel que celui de la chaussure, du vêtement, des sacs, ou autre.Still, although the exemplary clamping device has been described for application in the field of a snowboard binding, it can be provided to use the device in another technical field such as that of the shoe, the garment. , bags, or whatever.
