Description

DISPOSITIF DE FIXATION A RESSORT DE COMPRESSION FIXING DEVICE WITH COMPRESSION SPRING
L'invention se rapporte à un dispositif de fixation d'une chaussure à un article de sport.The invention relates to a device for attaching a shoe to a sports article.
L'invention pourra s'appliquer notamment à des dispositifs de fixation d'une chaussure sur un ski. Elle pourra notamment être mise en œuvre pour la conception de fixations de ski de fond, de ski de randonnée alpine, de ski de randonnée nordique ou de ski Telemark.The invention may be applied in particular to devices for attaching a boot to a ski. It can in particular be implemented for the design of cross-country ski bindings, alpine ski touring, Nordic ski touring or Telemark ski.
Un tel type de fixation est décrit dans la demande de brevet WOOO/13755 auquel on se référera utilement pour une compréhension globale du fonctionnement d'une telle fixation. Un dispositif du même genre, plus spécifiquement dédié à la randonnée alpine et au Télémark est décrit dans la demande de brevet EP-A1-890.379.Such a type of attachment is described in patent application WOOO / 13755 to which reference will usefully be made for a global understanding of the operation of such an attachment. A device of the same kind, more specifically dedicated to alpine hiking and Telemark is described in patent application EP-A1-890,379.
Le principe d'un tel dispositif est de permettre une fixation de la chaussure sur le ski qui soit parfaitement rigide en torsion mais qui permette un libre soulèvement du talon de la chaussure. Le dispositif décrit dans le document WO00/13755 est un perfectionnement des systèmes de fixation actuellement utilisés par exemple en ski de fond ou en ski de randonnée dans lesquels la chaussure est articulée par son extrémité avant autour d'un axe transversal par rapport au ski. En effet, le mouvement du pied par rapport au ski, lors du soulèvement du talon, est un mouvement qui n'est plus une simple rotation et qui se rapproche le plus possible du mouvement naturel de déroulement du pied.The principle of such a device is to allow a binding of the boot on the ski which is perfectly rigid in torsion but which allows free lifting of the heel of the boot. The device described in document WO00 / 13755 is an improvement on the binding systems currently used, for example in cross-country skiing or in ski touring in which the boot is articulated by its front end around an axis transverse to the ski. Indeed, the movement of the foot relative to the ski, during the lifting of the heel, is a movement which is no longer a simple rotation and which is as close as possible to the natural movement of the foot.
L'invention pourra aussi être mise en œuvre dans le cadre d'un dispositif de fixation du type de ceux décrits dans le document WO96/37269.The invention may also be implemented in the context of a fixing device of the type described in document WO96 / 37269.
L'invention vise à apporter un perfectionnement à ce genre de fixations. En effet, notamment pour la pratique du ski de fond, il est nécessaire que la fixation comporte des moyens de rappel élastique qui ramènent l'organe de liaison vers sa position basse qui correspond à la position qu'il occupe lorsque la chaussure à laquelle il est lié est en appui à l'avant et à l'arrière sur le ski. Ces moyens de rappel élastique doivent être suffisamment puissants pour ramener rapidement l'organe de liaison à cette position basse. Par exemple, lors de la pratique du pas du patineur en ski de fond, ce rappel intervient lorsque, en fin de poussée, le skieur veut ramener le ski vers l'avant en le soulevant de la neige. Dans ce cas, il apparaît que c'est l'avant du ski que les moyens de rappel doivent ramener vers le haut par rapport à la position de la chaussure de l'utilisateur. Si le rappel n'est pas suffisamment puissant, la spatule avant du ski va tarder à remonter et risque d'accrocher la neige, perturbant gravement la progression du skieur. Toutefois, ces moyens de rappel élastique doivent aussi présenter une bonne progressivité dans l'augmentation de l'effort en fonction de l'angle de soulèvement de l'organe de liaison, et leur action ne doit pas non plus opposer une trop grande résistance au mouvement de déroulé de pied.The invention aims to provide an improvement to this kind of fasteners. Indeed, in particular for the practice of cross-country skiing, it is necessary that the binding comprises elastic return means which bring the connecting member back to its low position which corresponds to the position which it occupies when the boot to which it is linked is supported at the front and rear on the ski. These elastic return means must be powerful enough to quickly bring the connecting member to this low position. For example, when practicing the skater's step in cross-country skiing, this reminder occurs when, at the end of the push, the skier wants to bring the ski forward by lifting it from the snow. In this case, it appears that it is the front of the ski that the return means must bring up relative to the position of the shoe of the user. If the recall is not strong enough, the front ski tip will take a long time to go up and risk catching the snow, seriously disrupting the skier's progress. However, these elastic return means must also have good progressiveness in increasing the force as a function of the lifting angle of the connecting member, and their action must not oppose too great resistance to foot roll movement.
Une autre contrainte à laquelle doivent répondre les moyens de rappel élastique est de ne pas présenter une trop grand encombrement, ni un poids trop élevé.Another constraint to which the elastic return means must respond is not to have too much space, or too much weight.
Dans ce but, l'invention propose un dispositif de fixation d'une chaussure à un article de sport, du type comportant une embase qui est destinée à être fixée à l'article de sport, et un organe de liaison à la chaussure, l'organe de liaison étant relié à l'embase par au moins une biellette, du type dans lequel l'organe de liaison est susceptible de se déplacer par rapport à l'embase entre une position basse et une position haute, et du type comportant des moyens de rappel élastique de l'organe de liaison vers sa position basse, caractérisé en ce que les moyens de rappel comportent un ressort de compression qui est lié à l'organe de liaison qui est comprimé par une extrémité d'un levier dont l'extrémité opposée est articulée sur le dispositif. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit ainsi qu'à la vue des dessins annexés dans lesquels : la figure 1 est une vue schématique, en coupe selon le plan longitudinal et vertical I-I indiqué à la figure 3, d'un dispositif de fixation conforme aux enseignements de l'invention, illustré en position haute ; la figure 2 est une vue similaire à celle de la figure 1, dans laquelle le dispositif de fixation est illustré en position basse ; et la figure 3 est une vue schématique de dessus du dispositif de fixation des figures 1 etTo this end, the invention provides a device for fixing a shoe to a sporting article, of the type comprising a base which is intended to be fixed to the sporting article, and a shoe connecting member, the connecting member being connected to the base by at least one link, of the type in which the link member is capable of moving relative to the base between a low position and a high position, and of the type comprising elastic return means of the connecting member to its low position, characterized in that the return means comprise a compression spring which is connected to the connecting member which is compressed by a end of a lever whose opposite end is articulated on the device. Other characteristics and advantages of the invention will appear on reading the detailed description which follows as well as on seeing the attached drawings in which: FIG. 1 is a schematic view, in section along the longitudinal and vertical plane II indicated in Figure 3, a fixing device according to the teachings of the invention, illustrated in the upper position; Figure 2 is a view similar to that of Figure 1, in which the fixing device is illustrated in the lower position; and Figure 3 is a schematic top view of the fastening device of Figures 1 and
2. Le dispositif de fixation 10 illustré sur les figures 1 à 3 comporte une embase 12 qui est destinée à être fixée sur un article de sport (non représenté), mais qui pourrait aussi être directement intégré dans ce dernier. Le dispositif de fixation 10 comporte encore un organe de liaison 14 sur lequel la chaussure est destinée à être accrochée. Cet accrochage peut être un accrochage définitif (la chaussure sera alors définitivement associée au dispositif de fixation 10 et à l'article de sport, et l'organe de liaison peut alors être directement intégré à la chaussure) ou cet accrochage peut être réalisé par un système d'interface détachable non représenté. Dans ce dernier cas, le système sera de préférence un système d'interface de type "step-in" dans lequel l'accrochage de la chaussure sur l'organe de liaison 14 s'effectue de manière automatique, par simple contact entre les deux. Le décrochage imposera généralement une action manuelle de l'utilisateur.2. The fastening device 10 illustrated in FIGS. 1 to 3 comprises a base 12 which is intended to be fixed to a sporting article (not shown), but which could also be directly integrated into the latter. The fastening device 10 also includes a connecting member 14 on which the shoe is intended to be hung. This attachment can be a permanent attachment (the shoe will then be permanently associated with the fastening device 10 and the sports article, and the connecting member can then be directly integrated into the shoe) or this attachment can be achieved by a detachable interface system not shown. In the latter case, the system will preferably be an interface system of the "step-in" type in which the attachment of the shoe to the connecting member 14 takes place automatically, by simple contact between the two. . Dropping out will generally require manual user action.
Comme décrit dans le document WO00/13755 l'organe de liaison est prévu pour être fixé sous la partie avant de la chaussure et pour basculer entre une position basse illustrée à la figure 2 (l'organe de liaison est alors sensiblement horizontal) et une position haute illustrée à la figure 1 lorsque le talon de l'utilisateur se soulève par rapport au ski.As described in document WO00 / 13755, the connecting member is designed to be fixed under the front part of the shoe and to switch between a low position illustrated in FIG. 2 (the connecting member is then substantially horizontal) and a high position illustrated in FIG. 1 when the user's heel is raised relative to the ski.
L'organe de liaison 14, d'orientation longitudinale, est lié à l'embase par une biellette 16 qui est montée à rotation autour de deux axes transversaux Al et A2 d'une part sur un plot (non représenté) de l'embase 12, et d'autre part sur l'organe de liaison 14. La biellette est elle aussi d'orientation longitudinaleThe connecting member 14, of longitudinal orientation, is linked to the base by a link 16 which is rotatably mounted around two transverse axes A1 and A2 on the one hand on a stud (not shown) of the base 12, and secondly on the connecting member 14. The link is also of longitudinal orientation
Dans les exemples illustrés, la biellette 16 est articulée par son extrémité arrière (par rapport au sens longitudinal de l'article de sport) sur l'embase 12 et par son extrémité avant sur l'extrémité avant 20 de l'organe de liaison de sorte que, en position basse, la biellette et l'organe de liaison 14 sont imbriqués l'un dans l'autre. Pour cela, on peut par exemple prévoir que, tel que cela est illustré sur la figure 3, l'organe de liaison 14 est constitué en fait de deux éléments longitudinaux parallèles 15 décalés transversalement et réunis par des entretoises, la biellette 16 étant alors reçue entre les deux éléments parallèles. La biellette 16 illustrée sur la figure 3 est elle aussi conçue sous la forme de deux éléments longitudinaux parallèles 17 entretoisés.In the examples illustrated, the rod 16 is articulated by its rear end (relative to the longitudinal direction of the sports article) on the base 12 and by its front end on the front end 20 of the connecting member of so that, in the low position, the link and the connecting member 14 are nested one inside the other. For this, one can for example provide that, as illustrated in Figure 3, the connecting member 14 is in fact made up of two parallel longitudinal elements 15 offset transversely and joined by spacers, the rod 16 then being received between the two parallel elements. The link 16 illustrated in FIG. 3 is also designed in the form of two parallel longitudinal elements 17 braced.
On peut aussi prévoir que la biellette 16 soit constituée de deux éléments parallèles disposés de part et d'autre de l'organe de liaison 14. On peut encore mettre en œuvre l'invention en disposant la biellette en avant de l'organe de liaison, c'est à-dire en l'articulant par son extrémité avant sur l'embase et par son extrémité arrière sur l'extrémité avant de l'organe de liaison.It is also possible to provide that the link 16 consists of two parallel elements arranged on either side of the connecting member 14. It is also possible to implement the invention by placing the link in front of the connecting member. , that is to say by articulating it by its front end on the base and by its rear end on the front end of the connecting member.
En position basse, l'organe de liaison 14 est en appui, directement ou indirectement, sur l'embase 12 par son extrémité arrière 18.In the low position, the connecting member 14 is supported, directly or indirectly, on the base 12 by its rear end 18.
Lors du mouvement de soulèvement du talon, lorsque l'organe de liaison 14 passe de sa position basse à sa position haute, l'organe de liaison 14 est en appui sur l'embase par son extrémité avant qui présente, sur une partie au moins, un profil courbe 20. La forme et l'évolution du profil courbe 20 conditionnent, en fonction de l'orientation angulaire de l'organe de liaison, la position en hauteur de l'axe A2 par rapport à l'embase 12. Par un dessin optimal du profil courbe 20, et par un choix judicieux de la longueur et de l'angle initial de la biellette 16, on conditionne le mouvement relatif de l'organe de liaison 14 par rapport à l'embase 12 lors de la phase de soulèvement du talon. Dans l'exemple illustré, on voit que le mouvement angulaire de la biellette 16 est faible, par exemple de l'ordre de 10 à 20 degrés lorsque l'organe de liaison 14 bascule d'un angle de l'ordre d'une soixantaine de degrés, et que, compte tenu de l'angle initial de la biellette, il se traduit par un déplacement vers l'avant faible mais réel de l'axe A2. On notera que le mouvement de soulèvement du talon s'effectue grâce à un mouvement de roulement avec glissement du profil courbe 20 sur l'embase 12.During the heel lifting movement, when the connecting member 14 passes from its low position to its high position, the connecting member 14 is supported on the base by its front end which has, on at least part , a curved profile 20. The shape and the evolution of the curved profile 20 condition, as a function of the angular orientation of the connecting member, the position in height of the axis A2 relative to the base 12. By an optimal design of the curved profile 20, and by a judicious choice of the length and the initial angle of the link 16, the relative movement of the connecting member 14 relative to the base 12 is conditioned during the phase heel lift. In the example illustrated, it can be seen that the angular movement of the link 16 is small, for example of the order of 10 to 20 degrees when the connecting member 14 swings at an angle of the order of sixty of degrees, and that, taking into account the initial angle of the rod, it results in a small but real forward displacement of the axis A2. It will be noted that the heel lifting movement is carried out by means of a rolling movement with sliding of the curved profile 20 on the base 12.
Le dispositif de fixation 10 comporte aussi des moyens de rappel élastique de l'organe de liaison 14 vers sa position basse.The fixing device 10 also includes means for elastic return of the connecting member 14 to its low position.
Selon l'invention, les moyens élastiques comportent un ressort de compression 22 qui est lié à l'organe de liaison 14 et qui est actionné par un levier 24 articulé sur un autre élément du dispositif 10.According to the invention, the elastic means comprise a compression spring 22 which is linked to the connecting member 14 and which is actuated by a lever 24 articulated on another element of the device 10.
Dans l'exemple illustré, le ressort de compression 22 est un ressort en fil d'acier hélicoïdal, mais il pourrait aussi être réalisé selon toute autre manière équivalente, par exemple sous la forme d'un tampon en matériau élastique. De même, sur les figures, le ressort 22 est un ressort unique, mais on peut prévoir que le ressort de l'invention soit réalisé sous la forme de plusieurs éléments montés en parallèle.In the example illustrated, the compression spring 22 is a spring made of helical steel wire, but it could also be produced in any other equivalent manner, for example in the form of a buffer of elastic material. Similarly, in the figures, the spring 22 is a single spring, but provision can be made for the spring of the invention to be produced in the form of several elements mounted in parallel.
Le ressort de compression 22 est lié à l'organe de liaison 14 de manière à en suivre tous les mouvements. En position basse de l'organe de liaison, le ressort s'étend selon une direction longitudinale sensiblement horizontale. Une extrémité longitudinale avant du ressort 22 est en appui sur une surface de butée 23 de l'organe de liaison tandis que son extrémité arrière est prévue pour coopérer avec le levier 24. Dans l'exemple illustré, le levier 24 est réalisé sous la forme de deux éléments longitudinaux parallèles qui sont décalés transversalement de chaque côté d'un plan de symétrie longitudinal et vertical du dispositif 10 de manière à encadrer le ressort 22, et qui sont réunis à leur extrémité arrière par un élément transversal 30 sur lequel le ressort prend appui.The compression spring 22 is linked to the connecting member 14 so as to follow all its movements. In the lower position of the connecting member, the spring extends in a substantially horizontal longitudinal direction. A front longitudinal end of the spring 22 is supported on an abutment surface 23 of the connecting member while its rear end is provided to cooperate with the lever 24. In the example illustrated, the lever 24 is produced in the form of two parallel longitudinal elements which are offset transversely on each side of a plane of longitudinal and vertical symmetry of the device 10 so as to frame the spring 22, and which are joined at their rear end by a transverse element 30 on which the spring bears.
Le ressort 22 est monté sur une tige de guidage 26, solidaire de l'organe de liaison 14, de manière à pouvoir glisser et coulisser librement sur la tige. La tige de guidage 26 permet notamment d'éviter que le ressort 22 ne se déforme de manière trop importante en flambement. La tige de guidage 26 est ici rectiligne, mais elle pourrait aussi être courbe (dans le plan longitudinal et vertical de la figure). On remarque que, dans le mode de réalisation illustré, la surface de butée 23 est formée par un épaulement de la tige 26The spring 22 is mounted on a guide rod 26, integral with the connecting member 14, so as to be able to slide and slide freely on the rod. The guide rod 26 makes it possible in particular to prevent the spring 22 from deforming excessively in buckling. The guide rod 26 is here rectilinear, but it could also be curved (in the longitudinal and vertical plane of the figure). Note that, in the illustrated embodiment, the abutment surface 23 is formed by a shoulder of the rod 26
Dans l'exemple illustré, le levier 24 est articulé, par son extrémité avant 28, sur l'embase autour de l'axe Al, c'est-à-dire l'axe d'articulation de la biellette 16 sur l'embase 12. Cependant, on peut aussi prévoir que le levier soit articulé sur l'embase autour d'un autre axe transversal ou qu'il soit articulé sur un autre élément du dispositif. Ainsi, le levier 24 pourrait être articulé sur la biellette 16 au tour d'un axe transversal agencé entre les axes Al et A2.In the example illustrated, the lever 24 is articulated, by its front end 28, on the base around the axis A1, that is to say the axis of articulation of the rod 16 on the base 12. However, provision can also be made for the lever to be articulated on the base around another transverse axis or to be articulated on another element of the device. Thus, the lever 24 could be articulated on the link 16 around a transverse axis arranged between the axes A1 and A2.
L'extrémité arrière 30 du levier 24 est montée de manière coulissante sur la tige de guidage 26 et prend appui sur l'extrémité arrière du ressort 22. Des jeux de fonctionnement sont prévus pour empêcher tout coincement du mécanisme. Ainsi, lorsque l'organe de liaison se déplace entre ses positions haute et basse, il entraîne avec lui l'extrémité arrière 30 du levier. Comme le seul mouvement possible pour le levier 24 est un mouvement de rotation autour de l'axe Al, mouvement qui est donc différent de celui de l'organe de liaison (qui suit un mouvement de rotation autour de l'axe A2, lequel est un axe mobile en fonction de la position angulaire de l'organe de liaison), il apparaît donc un mouvement différentiel entre l'extrémité arrière du levier 24 et l'organe de liaison. Ce mouvement différentiel se traduit donc par une trajectoire de l'extrémité arrière du levier le long de la tige de guidage 26The rear end 30 of the lever 24 is slidably mounted on the guide rod 26 and bears on the rear end of the spring 22. Operating clearances are provided to prevent any jamming of the mechanism. Thus, when the connecting member moves between its high and low positions, it carries with it the rear end 30 of the lever. As the only possible movement for the lever 24 is a rotational movement around the axis A1, a movement which is therefore different from that of the connecting member (which follows a rotational movement around the axis A2, which is a movable axis as a function of the angular position of the connecting member), there therefore appears a differential movement between the rear end of the lever 24 and the connecting member. This differential movement therefore results in a trajectory of the rear end of the lever along the guide rod 26
De par la géométrie des pièces, on peut voir sur les figures 1 et 2 que, lorsque l'organe de liaison 14 passe de sa position basse à sa position haute, l'extrémité arrière 30 du levier 24 se rapproche de la surface de butée 23, en comprimant le ressort 22. On voit que l'extrémité avant de la tige 26 forme un T dont la partie transversale assure la fonction de tige d'articulation d'axe A2 entre l'organe de liaison 14 et la biellette 16. De la sorte, on voit que la force de poussée exercée par le ressort 22 sur l'organe de liaison est toujours dirigée en direction de l'axe A2. On voit aussi que cette force tend à créer, sur l'ensemble biellette/organe de liaison, un couple de rotation par rapport à l'axe Al qui force la rampe 20 en appui contre l'embase 12, quelle que soit la position angulaire de l'ensemble.From the geometry of the parts, it can be seen in FIGS. 1 and 2 that, when the connecting member 14 passes from its low position to its high position, the rear end 30 of the lever 24 approaches the abutment surface 23, by compressing the spring 22. It can be seen that the front end of the rod 26 forms a T, the transverse part of which acts as an articulation rod with an axis A2 between the connecting member 14 and the link 16. In this way, we see that the pushing force exerted by the spring 22 on the connecting member is always directed towards the axis A2. It can also be seen that this force tends to create, on the link / connecting member assembly, a torque relative to the axis Al which forces the ramp 20 to bear against the base 12, whatever the angular position from the whole.
Par réaction, l'extrémité arrière du ressort crée sur le levier 24 un couple autour de l'axe Al qui force l'extrémité arrière du levier vers le bas. Comme l'extrémité arrière du levier 24 est liée à l'organe de liaison par l'intermédiaire de la tige de guidage 26, le levier force l'extrémité arrière de l'organe de liaison en appui contre l'embase 12. Cette conception des moyens de rappel élastique est particulièrement intéressante par sa compacité. By reaction, the rear end of the spring creates on the lever 24 a torque around the axis A1 which forces the rear end of the lever down. As the rear end of the lever 24 is linked to the connecting member by means of the guide rod 26, the lever forces the rear end of the connecting member to bear against the base 12. This design of the elastic return means is particularly interesting by its compactness.
