Description

La présente invention concerne un dispositif de fixation intermédiaire de chaussures sur un ski du type de ceux qui permettent de monter sur un seul ski de largeur conventionnelle habituellement utilisé en paire, les deux chaussures d'un skieu l'une à côté de l'autre.The present invention relates to an intermediate binding device for boots on a ski of the type which makes it possible to ride on a single ski of conventional width usually used in pairs, the two boots of a skier side by side .

On connait actuellement différents dispositifs de ce type. On connait en particulier par le brevet FR 2 514 651 un dispositif intermédiaire de ce genre qui comprend un plancher portant les chaussures et une semelle fixée sur le ski, plancher et semelle qui sont reliés par deux montants. Ce dispositif connu présente l'inconvénient d'être rigide et d'être rigidement fixé sur le ski. Il s'ensuit que le ski devient rigide dans sa partie centrale et qu'il perd en grande partie ses qualités de flexion et de torsion.Various devices of this type are currently known. We know in particular from patent FR 2 514 651 an intermediate device of this kind which comprises a floor carrying the boots and a sole fixed to the ski, floor and sole which are connected by two uprights. This known device has the drawback of being rigid and of being rigidly fixed to the ski. It follows that the ski becomes rigid in its central part and that it largely loses its qualities of flexion and torsion.

La présente invention a notamment pour but d'éviter ces inconvénients et propose un dispositif de fixation intermédiaire de chaussures sur un ski du type comprenant un support apte à être fixé sur la face supérieure d'un ski et dont la face supérieure située à distance de la face supérieure du ski constitue une plate-forme sur laquelle peuvent être fixées des chaussures de ski, l'une à côté de l'autre, qui se caractérise par le fait qu'il comprend des moyens élastiques intermédiaires aptes à agir entre ledit support et le ski. De cette manière, le ski portant le dispositif de fixation intermédiaire selon la présente invention peut conserver les qualités de flexion et de torsion qu'il présente lorsqu'il porte sur sa face supérieure, directement, une seule chaussure.The present invention aims in particular to avoid these drawbacks and proposes an intermediate shoe fixing device on a ski of the type comprising a support capable of being fixed on the upper face of a ski and whose upper face located at a distance from the upper face of the ski constitutes a platform on which ski boots can be fixed, one next to the other, which is characterized by the fact that it comprises intermediate elastic means capable of acting between said support and skiing. In this way, the ski carrying the intermediate binding device according to the present invention can retain the qualities of flexion and torsion which it exhibits when it directly wears a single boot on its upper face.

Le dispositif de fixation intermédiaire selon la présente invention peut présenter de nombreuses variantes de réalisation.The intermediate fixing device according to the present invention can have many variant embodiments.

Il peut en effet comprendre en outre une semelle intermédiaire d'une part fixée sur ledit support et d'autre part apte à être fixé sur le ski, lesdits moyens élastiques intermédiaires comprenant au moins un élément élastique disposé entre ladite semelle et ledit support.It may in fact further comprise an intermediate sole on the one hand fixed on said support and on the other hand capable of being fixed on the ski, said intermediate elastic means comprising at least one elastic element disposed between said sole and said support.

Il peut également présenter des moyens élastiques intermédiaires comprenant des éléments élastiques disposés entre au moins certains des moyens de fixation de la semelle dudit support sur le ski et cette semelle.It may also have intermediate elastic means comprising elastic elements disposed between at least some of the means for fixing the sole of said support to the ski and this sole.

Dans une autre variante, il peut avantageusement comprendre une semelle intermédiaire formée par une lame en un matériau élastique qui d'une part est montée sur ledit support en deux zones d'appui espacées longitudinalement et d'autre part est apte à être fixée sur le ski en s'étendant sur la face supérieure de ce dernier, longitudinalement, cette semelle intermédiaire formée par un matériau élastique constituant en elle-même des moyens élastiques intermédiaires conformes à la présente invention.In another variant, it may advantageously comprise an intermediate sole formed by a blade made of a material elastic which on the one hand is mounted on said support in two support zones spaced longitudinally and on the other hand is capable of being fixed on the ski by extending on the upper face of the latter, longitudinally, this intermediate sole formed by an elastic material constituting in itself intermediate elastic means in accordance with the present invention.

Dans cette varianteômconformément à la présente invention, ladite semelle intermédiaire formée en un matériau élastiques est de préférence fixée sur le ski en deux zones situées à l'extérieur desdites zones d'appui espacées longitudinalement.In this variant, in accordance with the present invention, said intermediate sole formed of an elastic material is preferably fixed to the ski in two zones situated outside said longitudinally spaced support zones.

Selon la présente invention, une plaque intermédiaire en un matériau élastique peut avantageusement être prévue, dans au moins l'une desdites zones d'appui, entre ladite semelle intermédiaire et ledit support.According to the present invention, an intermediate plate made of an elastic material can advantageously be provided, in at least one of said bearing zones, between said intermediate sole and said support.

Il peut également être avantageux de prévoir entre les vis de fixation, d'au moins l'une des zones de fixation de la semelle intermédiaire sur le ski et cette semelle, des éléments élastiques.It may also be advantageous to provide elastic elements between the fixing screws, at least one of the areas for fixing the midsole to the ski and this sole.

Selon la présente invention, ladite semelle formée par une lame en un matériau élastique peut avantageusement se prolonger longitudinalement, vers l'avant et/ou vers l'arrière en s'étendant sur la face supérieure du ski, de telle sorte que cette semelle peut contribuer à renforcer le ski qui, s'il est conventionnel, doit porter à lui seul le poids du skieur.According to the present invention, said sole formed by a blade made of an elastic material can advantageously extend longitudinally, towards the front and / or towards the rear, extending over the upper face of the ski, so that this sole can contribute to strengthening the ski which, if it is conventional, must alone bear the weight of the skier.

Dans cette variante de réalisation, il peut apparaître comme avantageux qu'au moins l'un des prolongements de la semelle formée par une lame en un matériau élastique porte une cale disposée entre ce prolongement et le ski.In this variant embodiment, it may appear advantageous that at least one of the extensions of the sole formed by a blade made of an elastic material carries a shim disposed between this extension and the ski.

Dans une autre variante de réalisation, cette cale peut être portée par un curseur réglable longitudinalement le long de ce prolongement. Ainsi, la lame en un matériau élastique peut agir sur les caractéristiques du ski de manière réglable.In another alternative embodiment, this wedge can be carried by a slider adjustable longitudinally along this extension. Thus, the blade of an elastic material can act on the characteristics of the ski in an adjustable manner.

Dans une variante de réalisation, il est particulièrement avantageux que ladite lame en un matériau élastique soit formée par une lame en acier à ressort.In an alternative embodiment, it is particularly advantageous for said blade made of an elastic material to be formed by a spring steel blade.

La présente invention sera mieux comprise à l'étude d'un dispositif de fixation intermédiaire de chaussures sur un ski décrit à titre d'exemple non limitatif et illustré par le dessin sur lequel :

  • - la figure 1 représente une vue en élévation d'un dispositif de fixation intermédiaire selon la présente invention monté sur un ski ;
  • - la figure 2 représente une vue de dessus du dispositif de fixation intermédiaire représenté sur la figure 1 ;
  • - la figure 3 re,jésente une coupe longitudinale agrandie selon III-III de la figure 2, décalée par rapport à l'axe du ski ;
  • - et la figure 4 représente une coupe longitudinale agrandie selon IV-IV de la figure 2.
The present invention will be better understood from the study of an intermediate shoe binding device on a ski described by way of non-limiting example and illustrated by the drawing in which:
  • - Figure 1 shows an elevational view of an intermediate binding device according to the present invention mounted on a ski;
  • - Figure 2 shows a top view of the intermediate fixing device shown in Figure 1;
  • - Figure 3 re, I present an enlarged longitudinal section along III-III of Figure 2, offset from the axis of the ski;
  • FIG. 4 represents an enlarged longitudinal section along IV-IV of FIG. 2.

Le dispositif de fixation intermédiaire représenté sur les figures et repéré d'une manière générale par la référence 1 est monté sur un ski conventionnel 2 habituellement utilisé par paire.The intermediate binding device shown in the figures and generally identified by the reference 1 is mounted on a conventional ski 2 usually used in pairs.

Ce dispositif de fixation intermédiaire comprend un support repéré d'une manière générale par la référence 3 qui comprend une plate-forme 4 dont la face supérieure 5 horizontale est parallèle à la face supérieure 6 du ski 2 et située à distance. Le support 3 présente également un pied avant 7 et un pied arrière 8 qui s'étendent vers le bas à partir de la plate-forme 4 et qui sont espacés dans le sens longitudinal, ces pieds présentant des surfaces d'extrémité inférieure 9 et 10 parallèles à la face supérieure 5. Comme on peut le voir sur la figure 3, le support 3 comprend, en exemple, une enveloppe 11 faite en résine synthétique armée de fibres de verre ou en matière plastique injectée ou moulée, cette enveloppe 11 étant remplie par une mousse en matière plastique.This intermediate fixing device comprises a support generally identified by the reference 3 which comprises a platform 4, the upper horizontal face 5 of which is parallel to the upper face 6 of the ski 2 and located at a distance. The support 3 also has a front foot 7 and a rear foot 8 which extend downwards from the platform 4 and which are spaced in the longitudinal direction, these feet having lower end surfaces 9 and 10 parallel to the upper face 5. As can be seen in FIG. 3, the support 3 comprises, for example, an envelope 11 made of synthetic resin reinforced with glass fibers or of injected or molded plastic, this envelope 11 being filled by a plastic foam.

Comme on peut le voir plus précisément sur la figure 2, la face supérieure 5 du support 3 est sensiblement rectangulaire et porte dans sa partie avant deux fixations avant 12 et 13 et dans sa partie arrière deux fixations arrière 14 et 15 qui sont d'un type conventionnel et qui sont prévues pour maintenir sur la plate-forme 4 deux chaussures de ski, l'une à côté de l'autre, et situées de manière symétrique par rapport à l'axe longitudinal du ski 2. Les moyens de fixation des fixations 12, 13, 14 et 15 n'ont pas été représentés sur les figures mais peuvent être formées, de manière conventionnelle, par des vis, le support 3 pouvant par ailleurs présenter des insères de renforcement pour le maintien de ces vis de fixation.As can be seen more precisely in FIG. 2, the upper face 5 of the support 3 is substantially rectangular and carries in its front part two front fixings 12 and 13 and in its rear part two rear fixings 14 and 15 which are of a conventional type and which are provided for holding on the platform 4 two ski boots, one next to the other, and located symmetrically with respect to the longitudinal axis of the ski 2. The means of fixing the fasteners 12, 13, 14 and 15 have not been shown in the figures but may be formed, in a conventional manner, by screws, the support 3 possibly also having reinforcement inserts for holding these fastening screws.

Le dispositif de fixation intermédiaire 1 comprend également une semelle formée par une lame en acier à ressort 16 qui s'étend longitudinalement et à plat sur la face supérieure 6 du ski 2, en-dessous des pieds 7 et 8 du support 3.The intermediate binding device 1 also comprises a sole formed by a spring steel blade 16 which extends longitudinally and flat on the upper face 6 of the ski 2, below the feet 7 and 8 of the support 3.

Cette lame en acier à ressort 16 est fixée au pied avant 7 du support 3 grâce à une paire de vis 17 disposées symétriquement par rapport à l'axe longitudinal du ski et est fixée au pied 8 du support 3 grâce à deux paires de vis 18 et 19 qui sont également disposées symétriquement par rapport à l'axe longitudinal du ski 2, les vis 17, 18 et 19 étan:.â têtes fraisées qui sont insérées dans la face inférieure 16a de la lame en acier à ressort 16.This spring steel blade 16 is fixed to the front foot 7 of the support 3 by a pair of screws 17 arranged symmetrically with respect to the longitudinal axis of the ski and is fixed to the foot 8 of the support 3 by two pairs of screws 18 and 19 which are also arranged symmetrically with respect to the longitudinal axis of the ski 2, the screws 17, 18 and 19 are: milled heads which are inserted into the lower face 16a of the spring steel blade 16.

La lame en acier à ressort 16 n'est pas directement en appui sur les faces inférieures 8 et 9 des pieds 7 et 8 du support 3. En effet, on a prévu entre la face supérieure 16b de la lame en acier à ressort 16 et les faces inférieures 8 et 9 des pieds 7 et 8 du support 3, respectivement deux plaques 20 et 21 qui sont respectivement traversées par les vis 17 et 18, 19 et qui sont en une matière plastique élastique telle qu'un élastomère.The spring steel blade 16 is not directly supported on the lower faces 8 and 9 of the feet 7 and 8 of the support 3. In fact, provision has been made between the upper face 16b of the spring steel blade 16 and the lower faces 8 and 9 of the feet 7 and 8 of the support 3, respectively two plates 20 and 21 which are respectively crossed by the screws 17 and 18, 19 and which are made of an elastic plastic material such as an elastomer.

La largeur de la lame en acier à ressort 16 est légèrement inférieure à la largeur du ski, la largeur des plaques intermédiaires 20 et 21 est sensiblement égale à la largeur de la lame en acier à ressort 16, ces plaques intermédiaires 20 et 21 couvrant la surface des faces inférieures 9 et 10 des pieds 7 et 8 du support 3, pieds qui vont, en section transversale, en s'évasant vers le haut pour rejoindre les bords longitudinaux de la plate-forme 4 du support 3.The width of the spring steel blade 16 is slightly less than the width of the ski, the width of the intermediate plates 20 and 21 is substantially equal to the width of the spring steel blade 16, these intermediate plates 20 and 21 covering the surface of the lower faces 9 and 10 of the feet 7 and 8 of the support 3, feet which go, in cross section, widening upwards to join the longitudinal edges of the platform 4 of the support 3.

A l'extérieur des pieds 7 et 8 du support 3, la lame en acier à ressort 16 est fixée au ski 2, à l'avant du pied 7 du support 3 par une paire de vis 22 disposées symétriquement par rapport à l'axe longitudinal du ski 2 et à l'arrière du pied 8 du support 3 par deux paires de vis 23 et 24 disposées également symétriquement par rapport à l'axe longitudinal du ski. Les vis 22, 23 et 24 traversent la lame en acier à ressort 16 et, entre leur tête et la face supérieure 16b de la lame en acier à ressort 16 sont respectivement prévus des ressorts de compression 25, 26 et 27 qui pourraient être remplacés par des rondelles Belleville ou par des rondelles en une matière plastique élastique telle qu'un élastomère. Comme on peut le voir sur la figure 3, les vis 22 traversent des trous oblongs 22a qui s'étendent longitudinalement.Outside the feet 7 and 8 of the support 3, the spring steel blade 16 is fixed to the ski 2, at the front of the foot 7 of the support 3 by a pair of screws 22 arranged symmetrically with respect to the axis longitudinal of the ski 2 and at the rear of the foot 8 of the support 3 by two pairs of screws 23 and 24 also arranged symmetrically with respect to the longitudinal axis of the ski. The screws 22, 23 and 24 pass through the spring steel blade 16 and, between their head and the upper face 16b of the spring steel blade 16 are provided respectively compression springs 25, 26 and 27 which could be replaced by Belleville washers or by washers made of an elastic plastic material such as an elastomer. As can be seen in Figure 3, the screws 22 pass through oblong holes 22a which extend longitudinally.

Grâce à la structure du dispositif de fixation intermédiaire 1 décrit ci-dessus, on peut se rendre compte que la lame en acier à ressort 16 peut effectuer, grâce aux plaques intermédiaires élastiques 20 et 21 disposées entre cette lame 16 et les pieds 7 et 8 du support 3, des mouvements de flexion et/ou de torsion. De plus, grâce aux ressorts 25, 26 et 27 prévus entre la lame en acier à ressort 16 et les vis de fixation 22, 23 et 24 de cette lame 16 sur le ski 2, des mouvements relatifs de flexion et/ou de torsion peuvent se produire entre la lame 16 et le ski 2. En outre, comme les zones de fixation de la lame en acier à ressort 16 sur le ski 2 et sur les pieds 7 et 8 du support 3 sont respectivement espacées longitudinalement, la lame 16 peut effectuer, entre ces zones, des mouvements de flexion et de torsion. Il s'ensuit que, même si le support 3 est rigide, le ski 2 peut effectuer par rapport à ce support 3 des mouvements de torsion et/ou de flexion sensiblement comme si le ski 2 portait une seule chaussure de manière classique en appui sur sa face supérieure 6, entre deux fixations fixées directement sur cette face supérieure 6.Thanks to the structure of the intermediate fixing device 1 described above, one can realize that the spring steel blade 16 can perform, thanks to the elastic intermediate plates 20 and 21 disposed between this blade 16 and the feet 7 and 8 of the support 3, bending and / or twisting movements. In addition, thanks to the springs 25, 26 and 27 provided between the spring steel blade 16 and the fixing screws 22, 23 and 24 of this blade 16 on the ski 2, relative movements of bending and / or torsion can occur between the blade 16 and the ski 2. In addition, since the areas of attachment of the spring steel blade 16 on the ski 2 and on the legs 7 and 8 of the support 3 are respectively spaced apart longitudinally, the blade 16 can perform bending and twisting movements between these areas. It follows that, even if the support 3 is rigid, the ski 2 can perform relative to this support 3 twisting and / or bending movements substantially as if the ski 2 wore a single shoe in a conventional manner bearing on its upper face 6, between two fasteners fixed directly on this upper face 6.

Comme on peut le voir sur les figures 1 et 2, la lame en acier à ressort 16 se prolonge largement en avant du pied 7 du support 3, vers la spatule 2a du ski 2 et en arrière du pied 8 du support 3 vers le talon 2b du ski 2. Ainsi, la lame en acier à ressort 16 est en appui sur la partie centrale du ski 2 au-delà des vis de fixation 22 et 24 et contribue à renforcer ce dernier qui doit porter le poids total du skieur.As can be seen in Figures 1 and 2, the spring steel blade 16 extends largely in front of the foot 7 of the support 3, towards the tip 2a of the ski 2 and behind the foot 8 of the support 3 towards the heel 2b of the ski 2. Thus, the spring steel blade 16 is supported on the central part of the ski 2 beyond the fixing screws 22 and 24 and contributes to strengthening the latter which must bear the total weight of the skier.

Comme cette lame en acier à ressort 16 est sensiblement rectiligne et que le ski 2 est cambré, il existe un espace croissant en épaisseur entre la face supérieure 6 du ski 2 et la face inférieure 16a de la lame en acier à ressort 16 dans les parties avant et arrière de ses prolongements libres avant 16c et arrière 16d.As this spring steel blade 16 is substantially rectilinear and the ski 2 is arched, there is an increasing space in thickness between the upper face 6 of the ski 2 and the lower face 16a of the spring steel blade 16 in the parts front and rear of its free extensions before 16c and rear 16d.

Sur les prolongements avant et arrière 16c et 16d de la lame en acier à ressort 16 sont montées des curseurs 28 et 29 qui sont traversés par cette lame 16 et qui sont mobiles longitudinalement le long de cette dernière.On the front and rear extensions 16c and 16d of the spring steel blade 16 are mounted sliders 28 and 29 which are crossed by this blade 16 and which are movable longitudinally along the latter.

En se reportant à la figure 4, on voit que le curseur 28 présente une partie inférieure bombée 30 qui s'étend entre la face supérieure 6 du ski 2 et la face inférieure 16a de la lame en acier à ressort 16 et que la partie supérieure 31 de ce curseur 28 porte une vis 32 susceptible de venir en appui sur la face supérieure 16b de la lame en acier à ressort 16 de manière à maintenir le curseur 28 le long de la lame en acier à ressort 16. Le curseur 29 est construit de la même manière que le curseur 28.Referring to FIG. 4, it can be seen that the cursor 28 has a curved lower part 30 which extends between the upper face 6 of the ski 2 and the lower face 16a of the spring steel blade 16 and that the upper part 31 of this cursor 28 carries a screw 32 capable of coming to bear on the upper face 16b of the spring steel blade 16 so as to maintain the cursor 28 along the spring steel blade 16. The cursor 29 is constructed in the same way as the cursor 28.

Grâce à ces curseurs 28 et 29, la lame en acier à ressort 16 agit agit vers le bas, par leur partie bombée 30 formant cale située entre la lame 16 et le ski 2, sur la partie avant et la partie arrière du ski 2 aussi bien dans ses mouvements de torsion que dans ses mouvements de flexion. De plus, en réglant les positions longitudinales des curseurs 28 et 29 le long de la lame en acier à ressort 16, on peut modifier à volonté l'influence de la lame en acier à ressort 16 sur les caractéristiques mécaniques du ski 2.Thanks to these sliders 28 and 29, the spring steel blade 16 acts downwards, by their convex part 30 forming wedge located between the blade 16 and the ski 2, on the front part and the rear part of the ski 2 both in its twisting movements and in its bending movements. In addition, by adjusting the longitudinal positions of the sliders 28 and 29 along the spring steel blade 16, the influence of the spring steel blade 16 on the mechanical characteristics of the ski 2 can be modified as desired.

La présente invention ne se limite pas à l'example ci-dessus décrit. On aurait pu en effet prévoir une semlle intermédiaire formée par une lame en un autre matériau. On pourrait éventuellement supprimer certains des moyens élastiques prévus. Bien d'autres variantes de réalisation sont possibles sans sortir du cadre défini par les revendications annexées.The present invention is not limited to the example described above. We could indeed have provided an intermediate semlle formed by a blade of another material. We could possibly remove some of the elastic means provided. Many other alternative embodiments are possible without departing from the scope defined by the appended claims.
