Description

Domaine techniqueTechnical area

L'invention se rattache au domaine des sports de glisse sur neige, et plus particulièrement du ski alpin. Elle concerne plus précisément un dispositif de montage sur un ski des éléments d'une fixation de sécurité, à savoir la talonnière et la butée.The invention relates to the field of snow sports, especially Alpine skiing. It relates more specifically to a mounting device on a ski elements of a safety binding, namely the heel and the stop.

Techniques antérieuresPrevious techniques

De façon générale, de très nombreuses solutions ont déjà été proposées, pour permettre le montage des éléments de la fixation non pas directement sur la face supérieure du ski, mais sur un dispositif intermédiaire. Ce type de dispositif intermédiaire peut être employé dans plusieurs objectifs. Ainsi, pour les skis destinés à la location, il est intéressant que les fixations possèdent une capacité de réglage longitudinal, et l'emploi d'un dispositif intermédiaire permet d'éviter de réaliser de multiples perçages sur la face supérieure du ski. Une telle capacité de réglage est notamment décrite dans le document FR 2 820 335.In general, many solutions have already been proposed, to allow the mounting of the elements of the binding not directly on the upper face of the ski, but on an intermediate device. This type of intermediate device can be used for several purposes. Thus, for skis for rental, it is interesting that the fasteners have a longitudinal adjustment capability, and the use of an intermediate device avoids making multiple holes on the upper face of the ski. Such adjustment capacity is described in particular in document FR 2 820 335.

Les dispositifs intermédiaires permettent également de surélever la fixation, et de faciliter le basculement d'une carre sur l'autre, comme décrit dans le document EP 0 409 749.The intermediate devices also make it possible to raise the fastening, and to facilitate tilting from one edge to the other, as described in document EP 0 409 749.

D'un point de vue mécanique, ces dispositifs intermédiaires sont également utilisés pour assurer un débridage, c'est-à-dire limiter l'influence de la raideur de la semelle de la chaussure sur le comportement du skiFrom a mechanical point of view, these intermediate devices are also used to ensure debridement, that is to say, to limit the influence of the stiffness of the sole of the boot on the behavior of the ski

Le phénomène de débridage est relativement complexe, puisqu'il convient d'assurer un bon ancrage des éléments de la fixation, mais sans modifier trop fortement la raideur intrinsèque de la planche. C'est pourquoi des solutions ont déjà été proposées dans lesquelles une plaque de matériau viscoélastique est disposée sous la plateforme, tel qu'illustré dans le document FR 2 664 823.The phenomenon of debridement is relatively complex, since it is necessary to ensure a good anchoring of the elements of the binding, but without modifying too strongly the intrinsic stiffness of the board. This is why solutions have already been proposed in which a plate of viscoelastic material is placed under the platform, as illustrated in document FR 2,664,823.

Dans d'autres solutions, et notamment celle décrite dans le document FR 2 809 634, une partie de la plateforme peut être rendue mobile par rapport à la face supérieure du ski, en étant montée avec une capacité de coulissement par rapport à un point fixe solidaire de la face supérieure du ski.In other solutions, and in particular that described in document FR 2 809 634, a part of the platform can be made movable relative to the upper face of the ski, being mounted with a sliding capacity with respect to a fixed point integral with the upper face of the ski.

Exposé de l'inventionPresentation of the invention

L'invention concerne donc un dispositif de montage des éléments d'une fixation de sécurité sur un ski.The invention therefore relates to a device for mounting the elements of a safety binding on a ski.

Conformément à l'invention, ce dispositif comporte :

  • ■ une plate forme rigide s'étendant sur toute la longueur de la zone de montage de la fixation, et comportant des glissières latérales ;
  • ■ un élément en matériau élastomérique, s'étendant sous la plate forme rigide, et destiné à venir au contact de la face supérieure du ski ;
  • ■ deux butées, respectivement avant et arrière, coopérant avec la plate forme rigide pour en limiter le débattement longitudinal ;
  • ■ une plaque arrière, apte à recevoir la talonnière de la fixation, ladite plaque arrière étant mécaniquement liée à la plateforme rigide, et maintenue sur le ski par l'intermédiaire d'éléments de maintien qui sont fixés directement sur le ski de chaque coté de la plate forme rigide.
According to the invention, this device comprises:
  • A rigid platform extending over the entire length of the mounting area of the binding, and having lateral slides;
  • An element made of elastomeric material, extending under the rigid platform, and intended to come into contact with the upper face of the ski;
  • ■ two stops, respectively front and rear, cooperating with the rigid platform to limit the longitudinal movement;
  • A rear plate, adapted to receive the heel of the binding, said rear plate being mechanically connected to the rigid platform, and held on the ski by means of holding elements which are fixed directly on the ski on each side of the rigid platform.

De la sorte, la talonnière de la fixation est montée sur la plaque arrière qui elle-même repose sur la face supérieure de la plateforme en enjambant latéralement celle-ci, et en autorisant donc l'ensemble plateforme/plaque arrière à se déplacer longitudinalement par rapport au ski. Ce déplacement est toutefois limité par la présence des butées, notamment de la butée arrière, qui empêche le coulissement excessif de la plateforme vers l'arrière.In this way, the heel of the binding is mounted on the rear plate which itself rests on the upper face of the platform by stepping laterally thereof, and thus allowing the entire platform / back plate to move longitudinally by compared to skiing. This movement is however limited by the presence of stops, including the rear stop, which prevents the excessive sliding of the platform to the rear.

En pratique, cette plaque arrière peut comporter des portions s'étendant vers le bas de chaque coté de la plateforme, et destinées à venir au quasi-contact de la face supérieure du ski. Ces portions caractéristiques définissent donc entre elles un canal à l'intérieur duquel est encastrée la plateforme rigide.In practice, this rear plate may comprise portions extending downwardly on each side of the platform, and intended to come into close contact with the upper face of the ski. These characteristic portions thus define between them a channel inside which is embedded the rigid platform.

Avantageusement en pratique, la plateforme rigide peut comporter des évidements latéraux, interrompant les glissières, de manière à permettre le passage des portions de la plaque arrière qui s'étendent vers le bas et qui viennent au quasi-contact de la face supérieure du ski. Ces évidements permettent donc la mise en place de cette plaque arrière au-dessus de la plateforme, tout en autorisant le déplacement longitudinal de la plaque arrière par rapport aux éléments de maintien.Advantageously in practice, the rigid platform may include lateral recesses, interrupting the slideways, so as to allow the passage of the portions of the rear plate which extend downwardly and which come into close contact with the upper face of the ski. These recesses thus allow the introduction of this back plate above the platform, while allowing the longitudinal displacement of the back plate relative to the holding elements.

En pratique, la butée de la fixation peut être solidarisée soit directement sur la plateforme rigide, soit avantageusement sur une plaque avant, solidarisée à la plateforme rigide par des agencements prévus à cet effet.In practice, the abutment of the fastener can be secured either directly on the rigid platform, or advantageously on a front plate, secured to the rigid platform by arrangements provided for this purpose.

Dans une forme particulière de réalisation, cette plaque avant peut être rendue apte à coulisser par rapport à la plateforme rigide, pour permettre la solidarisation à la plateforme en différentes positions de réglage longitudinal. De cette manière, le réglage de la position de la butée se fait en déplaçant la plaque avant, et en la bloquant sur la plateforme dans la position voulue.In a particular embodiment, this front plate can be made slidable relative to the rigid platform, to allow the attachment to the platform in different longitudinal adjustment positions. In this way, the adjustment of the position of the stop is done by moving the front plate, and blocking it on the platform in the desired position.

Cette plaque avant peut avantageusement venir au contact de la face supérieure du ski en enjambant latéralement la plateforme rigide, de manière à transmettre les appuis exercés sur la butée à destination de la planche. On s'affranchit ainsi de l'effet d'amortissement généré par la présence de l'élément en matériau élastomérique situé sous la plateforme rigide.This front plate can advantageously come into contact with the upper face of the ski by stepping laterally rigid platform, so as to transmit the support exerted on the stop to the board. This eliminates the damping effect generated by the presence of the elastomeric material element located under the rigid platform.

Cet élément en matériau élastomérique peut avantageusement comporter une zone proéminente interposée entre l'extrémité arrière de la plateforme rigide et la butée arrière.This element of elastomeric material may advantageously comprise a protruding zone interposed between the rear end of the rigid platform and the rear stop.

Cette zone remontant donc entre le point fixe de la butée arrière et la plateforme assure un effet d'amortisseur lors du déplacement de la plateforme rigide consécutif au cintrage du ski.This area thus rising between the fixed point of the rear stop and the platform provides a damping effect when moving the rigid platform following the bending of the ski.

Dans l'objectif de ne pas augmenter trop fortement la raideur générale du ski équipé des fixations, la plateforme peut avantageusement présenter une structure tubulaire, définissant des canaux longitudinaux de manière à conserver une bonne raideur en torsion tout en limitant le poids de l'ensemble.In order not to increase too much the general stiffness of the ski fitted with the bindings, the platform may advantageously have a tubular structure, defining longitudinal channels so as to maintain good torsional stiffness while limiting the overall weight. .

Dans le même esprit, la plateforme peut présenter en partie centrale des évidements transversaux ménagés sur sa face inférieure, et destinés à diminuer sa raideur en flexion.In the same spirit, the platform may have in the central part transverse recesses formed on its underside, and intended to reduce its stiffness in flexion.

Manière de réaliser l'inventionWay of realizing the invention

La figure 1 illustre l'ensemble du dispositif (1) destiné à assurer le montage des éléments de la fixation (non représentés) sur le ski (2). Plus précisément, le dispositif de montage (1) comporte une plateforme rigide (3), qui repose sur un élément (4) en matériau viscoélastique, lui-même reposant sur la face supérieure du ski (2).Figure 1 illustrates the assembly of the device (1) for mounting the elements of the binding (not shown) on the ski (2). More specifically, the mounting device (1) comprises a rigid platform (3), which rests on a member (4) of viscoelastic material, itself resting on the upper face of the ski (2).

Les butées avant (6) et arrière (5) coopèrent avec les extrémités de la plateforme rigide (3). Cette plateforme rigide reçoit sur sa face supérieure une plaque arrière (7) destinée à recevoir la talonnière (non représentée), tandis qu'une plaque avant (8) est prévue pour recevoir la butée (non représentée) de la fixation.The front (6) and rear (5) stops cooperate with the ends of the rigid platform (3). This rigid platform receives on its upper face a rear plate (7) for receiving the heel (not shown), while a front plate (8) is provided to receive the stop (not shown) of the binding.

Plus précisément, on observe à la figure 1 que la plateforme rigide (3) présente une structure tubulaire, et comporte des canaux (10, 11), s'étendant sur toute la longueur de la plateforme et permettant donc de réaliser cette dernière à partir d'un profilé. Ce profilé peut être réalisé en métal, et par exemple en alliage à base d'aluminium tel que du Zicral®, ou bien encore à base de matière plastique chargée de fibres.More specifically, it is observed in Figure 1 that the rigid platform (3) has a tubular structure, and comprises channels (10, 11) extending over the entire length of the platform and thus allowing the latter to be made from of a profile. This profile can be made of metal, for example aluminum-based alloy such as Zicral® , or else based on fiber-filled plastics material.

La plateforme (3) comporte latéralement deux glissières formées par une gorge (12) qui s'étend longitudinalement sur le côté de la plateforme (3).The platform (3) has laterally two rails formed by a groove (12) extending longitudinally on the side of the platform (3).

Dans des variantes non représentées, ces glissières peuvent être réalisées différemment, et notamment par un rétrécissement de la largeur de la plateforme définissant un rail apte à recevoir des zones proéminentes de l'organe destiné à coulisser sur la plateforme.In variants not shown, these slides can be made differently, and in particular by a narrowing of the width of the platform defining a rail adapted to receive protruding areas of the member intended to slide on the platform.

Dans la portion centrale, la plateforme (3) comporte des évidements (15) destinés à réduire la raideur en flexion de la plateforme rigide (3). Ces évidements sont réalisés par usinage du profilé formant la plateforme (3). Ces évidements (15) sont destinés à être comblés par des bossages (16) réalisés sur la face supérieure de l'élément élastomérique (4). Ces bossages (16) sont destinés à être comprimés lors des mouvements de flexion de la plateforme (3), et conférer des propriétés d'amortissement ou de ressort en fonction du matériau utilisé.In the central portion, the platform (3) has recesses (15) for reducing the bending stiffness of the rigid platform (3). These recesses are made by machining the profile forming the platform (3). These recesses (15) are intended to be filled by bosses (16) made on the upper face of the elastomeric element (4). These bosses (16) are intended to be compressed during bending movements of the platform (3), and to confer damping or spring properties depending on the material used.

Dans sa partie avant, la plateforme (3) comporte des perçages permettant de recevoir les vis de montage (18) sur la face supérieure de la planche. La plateforme (3) comporte également une pluralité de perçages centraux (19) destinés à recevoir la vis de blocage (20) de la plaque avant (8).In its front part, the platform (3) has holes for receiving the mounting screws (18) on the upper face of the board. The platform (3) also comprises a plurality of central bores (19) for receiving the locking screw (20) of the front plate (8).

Une pluralité de perçages (19) permet de régler la position longitudinale de la plaque avant (8) en fonction de la longueur de la chaussure.A plurality of holes (19) makes it possible to adjust the longitudinal position of the front plate (8) as a function of the length of the boot.

Sur sa face inférieure, la plateforme rigide (3) comporte des gorges (21), disposées latéralement et destinées à recevoir des nervures (22) formées sur la face supérieure de la couche élastomérique (4).On its underside, the rigid platform (3) has grooves (21), arranged laterally and intended to receive ribs (22) formed on the upper face of the elastomeric layer (4).

Ces nervures permettent notamment de limiter les passages de neige et d'eau, et surtout évitent l'échappement latéral de la couche élastomérique (4). Ces nervures (22) constituent également une zone compressible susceptible d'apporter un effet d'amortissement.These ribs make it possible in particular to limit the passage of snow and water, and especially avoid the lateral escape of the elastomeric layer (4). These ribs (22) also constitute a compressible zone capable of providing a damping effect.

Dans sa partie arrière, la couche élastomérique (4) comporte un renflement (25) destiné à recevoir sur sa face avant les appuis et les extrémités arrière de la plateforme (3). Ce renflement (25) est percé longitudinalement par une ouverture (26) destinée à recevoir une portion (28) orientée vers l'avant de la butée arrière (5). Lorsque la butée (5) est mise en place sur l'extrémité arrière (29) de la couche élastomérique (4), cette portion (28) traverse l'évidement (26), et pénètre à l'intérieur du canal central (27) de la plateforme rigide (3). Le débattement latéral de la plateforme est ainsi évité.In its rear part, the elastomeric layer (4) has a bulge (25) for receiving on its front face the supports and the rear ends of the platform (3). This bulge (25) is pierced longitudinally by an opening (26) for receiving a portion (28) facing the front of the rear stop (5). When the stop (5) is put in place on the rear end (29) of the elastomeric layer (4), this portion (28) passes through the recess (26), and penetrates inside the central channel (27). ) of the rigid platform (3). The lateral movement of the platform is avoided.

Le débattement longitudinal de la plateforme est limité par la compression de la zone proéminente (25) entre l'extrémité arrière de la plateforme (3) et la butée arrière (5) elle-même solidarisée à la face supérieure du ski par la vis (30).The longitudinal deflection of the platform is limited by the compression of the protruding zone (25) between the rear end of the platform (3) and the rear stop (5) itself secured to the upper face of the ski by the screw ( 30).

En effet, la partie arrière de la plateforme (3) possède une capacité de déplacement longitudinal conférée par l'architecture de la plaque arrière (7).Indeed, the rear part of the platform (3) has a longitudinal displacement capacity conferred by the architecture of the rear plate (7).

Plus précisément, cette plaque arrière (7) comporte une face supérieure (32) destinée à recevoir la talonnière par l'intermédiaire des vissages dans les perçages (33).More specifically, this rear plate (7) has an upper face (32) for receiving the heel via screwings in the holes (33).

La plaque arrière (7) comporte sur sa face inférieure des portions s'étendant vers le bas (34, 35) de manière à venir au quasi-contact de la face supérieure du ski (2). On ménage ainsi un faible jeu entre la plaque arrière et la face supérieure du ski, en vue d'éviter un frottement excessif lors du cintrage du ski. Entre les deux côtés de la plaque arrière (7), ces portions (35, 36) définissent un canal à l'intérieur duquel s'insère la plateforme (3). Comme illustré à la figure 6, les faces internes de ces portions (34, 35) comportent des renflements (36, 37) destinés à venir s'intégrer dans les évidements (38, 39) réalisés sur les côtés de la plateforme rigide (3).The rear plate (7) has downwardly extending portions (34,35) on its underside so as to come into close contact with the upper face of the ski (2). There is thus a small clearance between the rear plate and the upper face of the ski, to avoid excessive friction during bending of the ski. Between these two sides of the rear plate (7), these portions (35, 36) define a channel inside which the platform (3) is inserted. As shown in FIG. 6, the internal faces of these portions (34, 35) comprise bulges (36, 37) intended to fit into the recesses (38, 39) made on the sides of the rigid platform (3, 3). ).

De la sorte, la plaque arrière est solidaire de la plateforme pour les mouvements longitudinaux. Ce blocage est complété par la présence du plot (48) proéminent sous la face inférieure de la plaque arrière, et qui s'encastre dans le logement (58) ménagé sur la face supérieure de la plateforme rigide.In this way, the back plate is secured to the platform for longitudinal movements. This blocking is completed by the presence of the stud (48) prominent under the underside of the back plate, and which fits into the housing (58) formed on the upper face of the rigid platform.

Au-dessus des portions (34, 35) s'étendant vers le bas, la plaque arrière (7) comporte des évidements (40, 41) recevant des pièces complémentaires (42, 44). Les pièces (42, 44) disposées à l'arrière de la plaque (7) comportent dans la partie inférieure un canon (45) apte à recevoir les vis de fixation (47). Ce canon (45) pénètre à l'intérieur d'un évidement (46) qui présente des dimensions longitudinales supérieures, de telle sorte que la plaque arrière (7) peut se déplacer longitudinalement par rapport au point fixe que constitue la vis de montage (47), sous l'effet du déplacement de la plateforme (3).Above the downwardly extending portions (34, 35), the back plate (7) has recesses (40, 41) receiving complementary pieces (42, 44). The parts (42, 44) disposed at the rear of the plate (7) comprise in the lower part a gun (45) adapted to receive the fixing screws (47). This barrel (45) penetrates inside a recess (46) which has larger longitudinal dimensions, so that the rear plate (7) can move longitudinally with respect to the fixed point constituted by the mounting screw ( 47), under the effect of the displacement of the platform (3).

Les formes de la pièce d'attache (42, 44), notamment l'évidement (49) sont prévues pour permettre ce déplacement longitudinal. De même, les canons (50) de la pièce complémentaire (43) présentent une longueur dans le sens longitudinal qui est inférieure à celle de l'évidement (51) qui les reçoit.The shapes of the attachment piece (42, 44), including the recess (49) are provided to allow this longitudinal movement. Similarly, the barrels (50) of the complementary piece (43) have a length in the longitudinal direction which is less than that of the recess (51) which receives them.

Dans la partie avant, le dispositif conforme à l'invention comporte une butée (6) venant obturer les canaux (10, 11) de la plateforme (3), et constituent une pièce d'aspect reposant sur l'avant de la couche élastomérique (4).In the front part, the device according to the invention comprises an abutment (6) closing off the channels (10, 11) of the platform (3), and constitute a piece of appearance resting on the front of the elastomeric layer (4).

Cette butée (6) est maintenue en position par encastrement avec une zone proéminente (59) de la couche élastomérique (4).This abutment (6) is held in position by embedding with a prominent region (59) of the elastomeric layer (4).

Comme illustré à la figure 8, la plaque avant (8) comporte des portions latérales (55, 56) qui s'étendent verticalement et se prolongent au contact de la face supérieure de la planche.As illustrated in Figure 8, the front plate (8) has lateral portions (55, 56) which extend vertically and extend in contact with the upper face of the board.

Ces portions latérales (55, 56) présentent sur la face interne des guides (57) destinés à coopérer avec la glissière (12) de la plateforme rigide (3) lors du réglage en position longitudinale de la plaque avant sur ladite plateforme (3).These lateral portions (55, 56) have on the inner face guides (57) intended to cooperate with the slide (12) of the rigid platform (3) during the adjustment in longitudinal position of the front plate on said platform (3) .

En fonctionnement, la plateforme rigide (3) est fermement fixée par son extrémité avant sur la face supérieure du ski (2). La partie arrière de la plateforme est quant à elle, coulissante par rapport à la face supérieure du ski. En effet, la plaque arrière (7) présente une capacité de coulissement longitudinal par rapport au point fixe que constituent les vis de montage (47), grâce à la forme allongée des évidements (46). Il s'ensuit que lors d'un cintrage, la plaque arrière se trouve légèrement décalée vers l'arrière par le mouvement de la plateforme dont les déformations sont nettement inférieures à celles du ski.In operation, the rigid platform (3) is firmly fixed by its front end on the upper face of the ski (2). The rear part of the platform is slidable relative to the upper face of the ski. Indeed, the rear plate (7) has a longitudinal sliding capacity relative to the fixed point constituted by the mounting screws (47), thanks to the elongate shape of the recesses (46). It follows that during bending, the rear plate is slightly offset backwards by the movement of the platform whose deformations are significantly lower than those of the ski.

Le comportement des skis équipés de l'invention est particulièrement amélioré. En effet, on a observé que grâce au déplacement de l'ensemble plaque arrière/plateforme, le ski se déforme au mieux pour s'inscrire dans la courbe du virage. La puissance d'accrochage et la pression au niveau de la ligne de cotes sont ainsi augmentées, quel que soit le type de virage.The behavior of the skis equipped with the invention is particularly improved. Indeed, it was observed that by moving the rear plate / platform assembly, the ski deforms at best to fit into the curve of the turn. The hooking power and the pressure on the sidecut are thus increased, regardless of the type of turn.
