The body of the binding is on a base, forming a slide (4), and has a plate (9), supporting the boot. The slide moves on a base plate (11) which is joined to the ski by an articulation round a transversal axle at the back of the plate. A block of elastically deformable material (22) under the front end of the slide opposes its rocking. Feet (34, 35) on the front end of the slide are joined to the base plate by a bar (25). The ends of the bar are joined to the base plate and slide by two transversal axles (30, 31). <IMAGE>

Description

L'invention concerne un élément de fixation destiné à retenir l'extrémité d'une chaussure en appui sur une planche de glisse, notamment sur un ski. Plus précisément, l'invention concerne un élément de fixation destiné à retenir l'extrémité arrière d'une chaussure.The invention relates to a fastening element intended to retain the end of a shoe in support on a sliding board, especially on a ski. More specifically, the invention relates to an element of binding intended to retain the rear end of a shoe.

L'invention concerne également un ensemble de fixation destiné à retenir une chaussure sur un ski comprenant un tel élément de fixation.The invention also relates to a binding assembly intended to retain a boot on a ski. comprising such a fixing element.

De nombreux éléments de fixation arrière sont connus. Ils sont le plus souvent associés à un élément de fixation avant. Ils comprennent généralement une mâchoire de retenue de la chaussure portée par un corps. Le corps est mobile le long d'une embase ou glissière selon la direction longitudinale du ski, et un ressort, appelé couramment ressort de recul, s'oppose élastiquement au mouvement du corps vers l'arrière, en s'appuyant sur une butée. Cette butée, généralement un verrou ou une vis coopérant avec la glissière, définit la position nominale du corps. Cette position nominale est changée pour adapter l'élément de fixation à la longueur de la chaussure, ou pour modifier la force de rappel que le ressort de recul exerce sur la corps en présence de la chaussure.Many rear fasteners are known. They are most often associated with a front fixing element. They usually include a shoe retaining jaw carried by a body. The body is movable along a base or slide in the longitudinal direction ski, and a spring, commonly called recoil spring, resists the movement of the body back, leaning on a stop. This stopper, usually a latch or screw cooperating with the slide, defines the nominal position of the body. This nominal position is changed to adapt the fastening element to the length of the shoe, or to modify the restoring force that the recoil spring exerts on the body in the presence of the shoe.

L'élément de fixation arrière comprend également une plaque de support destinée à recevoir l'extrémité arrière de la semelle de chaussure. Cette plaque de support est associée habituellement ou bien au corps, ou bien à la glissière.The rear fastener also includes a support plate for receiving the rear end of the shoe sole. This support plate is usually associated or well to the body, or else to the slide.

Ces derniers temps, on a travaillé sur la liaison entre l'élément de fixation arrière et le ski, afin d'améliorer l'amortissement ou le filtrage des secousses ou chocs auxquels le ski est soumis, et par là le confort du skieur.Lately, we have been working on the connection between the rear binding element and the ski, in order to improve the damping or filtering of the jolts or shocks to which the ski is subjected, and thereby the comfort of the skier.

Ainsi, on a proposé des dispositifs où la glissière est isolée du ski par une couche de matériau amortissant. Un tel dispositif est par exemple connu d'après la demande de brevet français publiée sous le numéro FR 2 602 979. L'inconvénient de cette construction est que la couche de matériau amortissant isole totalement le ski et la chaussure, y compris pour les sensations que le skieur perçoit et les impulsions qu'il donne en réaction pour conduire son ski.Thus, devices have been proposed where the slide is isolated from the ski by a layer of material cushioning. Such a device is for example known from the published French patent application under the number FR 2 602 979. The disadvantage of this construction is that the layer of material shock absorbing completely isolates the ski and the boot, including for the sensations that the skier perceives and the impulses he gives in reaction to drive his ski.

La demande de brevet WO91/08807 propose une construction selon laquellé seulement la plaque d'appui de la chaussure est mobile et amortie par un bloc déformable. Cette construction donne de bons résultats. En effet, la liaison entre la plaque de support et la chaussure permet un amortissement sélectif des sollicitations. Les sollicitations verticales sont amorties, alors que les sollicitations de roulis transitent sans amortissement entre le ski et la chaussure.Patent application WO91 / 08807 proposes a construction according to lacquered only the support plate of the shoe is mobile and cushioned by a deformable block. This construction gives good results. Indeed, the connection between the support plate and the shoe allows selective damping of stresses. The vertical stresses are damped, while the rolling stresses pass without damping between the ski and the shoe.

L'inconvénient de cette construction est toutefois que la mâchoire de l'élément de fixation est aussi sollicitée lors de l'amortissement des sollicitations verticales. La mâchoire subit en effet et suit tous les mouvements verticaux de la semelle de chaussure.The disadvantage of this construction, however, is that the jaw of the fastening element is also stressed during the damping of vertical stresses. The jaw undergoes indeed and follows all the vertical movements of the shoe sole.

On connaít également d'après la demande de brevet publiée sous le numéro EP 567.780 un ensemble de retenue comprenant un élément de retenue avant et un élément de retenue arrière reliés entre eux par une plaque de transmission animée par un palpeur mobile verticalement. Le palpeur est porté par la glissière de l'élément arrière, dont l'extrémité avant repose en appui simple contre la branche horizontale d'un basculeur articulé. Un moyen de rappel élastique situé sous la glissière crée un effet de suspension du palpeur, ce qui apporte au skieur une sensation de confort. Toutefois, la liaison entre l'avant de la glissière et le ski ne permet pas une très bonne transmission des sollicitations latérales de la chaussure. En effet, cette liaison est prévue essentiellement pour transmettre des sollicitations verticales de la chaussure. Elle n'est pas prévue pour entraver efficacement un mouvement de roulis de l'avant de la glissière par rapport à la branche horizontale du basculeur.We also know from the patent application published under the number EP 567.780 a set retainer comprising a front retainer and a rear retainer interconnected by a transmission plate driven by a vertically movable probe. The probe is carried by the slide of the rear element, the front end of which rests in simple support against the branch horizontal of an articulated rocker. An elastic return means located under the slide creates a probe suspension, which gives the skier a feeling of comfort. However, the connection between the front of the slide and the ski does not allow very good transmission of the lateral stresses of the shoe. In fact, this link is mainly intended to transmit requests vertical of the shoe. It is not intended to effectively impede a roll movement from the front of the slide with respect to the horizontal branch of the rocker.

L'invention a pour but d'améliorer encore la liaison entre la chaussure et le ski.The invention aims to further improve the connection between the boot and the ski.

Un autre but de l'invention est aussi d'optimiser le compromis entre l'amortissement de la chaussure et la précision de la conduite du ski.Another object of the invention is also to optimize the compromise between the amortization of the shoe and the precision of the ski driving.

Un autre but est de proposer une construction qui soit simple à réaliser.Another aim is to propose a construction which is simple to carry out.

Ces buts sont atteints par l'élément de fixation tel qu'il est défini dans la revendication 1.These objects are achieved by the fixing element as defined in claim 1.

La mobilité en rotation de la glissière autour d'un axe transversal fait que l'élément de fixation dans son ensemble bascule au cours des mouvements verticaux. Il y a amortissement selon une direction verticale. De plus, on augmente l'inertie des éléments en mouvement. Les sollicitations de roulis transitent cependant sans amortissement entre la glissière et le ski, à cause de l'articulation transversale qui les relie.The rotational mobility of the slide around a transverse axis means that the fastening element as a whole rocks during vertical movements. There is amortization according to a vertical direction. In addition, the inertia of the moving elements is increased. Solicitations from roll however pass without damping between the slide and the ski, because of the articulation cross that connects them.

Selon une autre caractéristique de l'invention, on ajoute un moyen anti-roulis entre la glissière et le ski. Ce moyen améliore la qualité de la transmission des sollicitations en roulis qui transitent entre la chaussure et le ski.According to another characteristic of the invention, an anti-roll means is added between the slide and the ski. This means improves the quality of the transmission of the roll stresses which pass between the shoe and skiing.

D'autres buts et avantages de l'invention apparaítront au cours de la description qui va suivre et des dessins qui en font partie intégrante.Other objects and advantages of the invention will appear during the description which follows and drawings which form an integral part of it.

La figure 1 est une vue de côté, en coupe partielle d'un élément de fixation selon un premier mode de mise en oeuvre de l'invention.Figure 1 is a side view, in partial section of a fastening element according to a first embodiment for implementing the invention.

La figure 2 est une vue de côté en coupe de la plaque de base et de la glissière équipant l'élément de la figure 1.Figure 2 is a side sectional view of the base plate and the slide fitted to the element Figure 1.

La figure 3 est une vue partielle en perspective éclatée de la partie avant.Figure 3 is a partial exploded perspective view of the front part.

La figure 4 illustre une variante de réalisation de la biellette.Figure 4 illustrates an alternative embodiment of the link.

La figure 1 représente à titre l'illustration de l'invention un élément de fixation 1 comprenant de façon connue une mâchoire 2 de retenue de la chaussure portée par un corps 3. Le corps est monté coulissant le long d'une glissière 4 orientée selon la direction longitudinale définie par le ski. Un moyen tel qu'un verrou 5 cramponné dans la glissière définit une position nominale, et le corps peut reculer vers le verrou contre la force de rappel que lui oppose le ressort de recul 6.Figure 1 shows by way of illustration of the invention a fastening element 1 comprising known manner a shoe retaining jaw 2 carried by a body 3. The body is mounted sliding along a slide 4 oriented in the longitudinal direction defined by the ski. A way such as a latch 5 clamped in the slide defines a nominal position, and the body can move back towards the bolt against the restoring force opposed to it by the recoil spring 6.

La glissière représentée dans les figures présente en section une forme de "C" couché et ouvert vers le haut. Le corps est guidé dans la glissière par des patins qui circulent dans les bords repliés de la glissière. Ceci n'est pas limitatif et toute autre mode d'assemblage du corps sur la glissière convient, en particulier toute autre section appropriée de glissière.The slide shown in the figures has in section a shape of "C" lying and open to the top. The body is guided in the slide by skids which circulate in the folded edges of the slide. This is not limiting and any other method of assembling the body on the slide suitable, in particular any other suitable section of slide.

L'élément de fixation 1 présente également une plaque de support 9 qui est destinée à recevoir l'appui de la chaussure. The fixing element 1 also has a support plate 9 which is intended to receive the support of the shoe.

Dans le mode de réalisation illustré, la plaque de support 9 présente vers le bas et vers l'arrière un embout 10 qui est emboíté dans le profilé de la glissière. Avantageusement, cet embout est situé sous la plate-forme de la plaque 9 de façon à pouvoir être engagé sur la glissière depuis l'arrière, et être coulissé le long de la glissière jusqu'à sa position de service de la figure 1.In the illustrated embodiment, the support plate 9 has downwards and backwards a end piece 10 which is fitted into the profile of the slide. Advantageously, this tip is located under the platform of the plate 9 so that it can be engaged on the slide from the rear, and be slid along the slide to its service position in Figure 1.

La glissière est enveloppée dans une plaque de base 11.The slide is wrapped in a base plate 11.

La plaque de base 11 est destinée à être assemblée au ski par tout moyen approprié, par exemple par des vis. Elle présente un fond 12 destiné à être plaqué contre le ski. Le fond peut présenter de larges ouvertures. Latéralement, la plaque de base présente deux ailes 13 et 14 qui remontent le long des bords latéraux de la glissière 4. Ces ailes se referment au dessus de la glissière 4 par des rebords 15, 16, qui laissent entre eux un écartement suffisant pour que le corps puisse passer.The base plate 11 is intended to be assembled to the ski by any suitable means, for example by screws. It has a bottom 12 intended to be pressed against the ski. The background may show large openings. Laterally, the base plate has two wings 13 and 14 which go up along lateral edges of the slide 4. These wings close above the slide 4 by flanges 15, 16, which leave a sufficient distance between them so that the body can pass.

Le fond 12 et les rebords 15 et 16 sont légèrement convergents vers l'arrière de telle façon que selon une direction verticale, il n'y ait pas de jeu entre la partie arrière de la glissière 4 et la plaque de base. Un jeu existe toutefois sur l'avant de la glissière.The bottom 12 and the edges 15 and 16 are slightly convergent towards the rear so that in a vertical direction, there is no play between the rear part of the slide 4 and the plate based. There is, however, a clearance on the front of the slide.

De plus, la partie arrière de la glissière présente un patte horizontale 18. Cette patte est éventuellement divisée en deux segments. La patte 18 est logée dans un évidement 19 de dimension correspondante de la plaque de base, de façon à empêcher tout mouvement vers l'arrière de la glissière 4 par rapport à la plaque de base. Un mouvement relatif vers l'avant est toutefois possible.In addition, the rear part of the slide has a horizontal tab 18. This tab is possibly divided into two segments. The tab 18 is housed in a recess 19 of dimension base plate, so as to prevent backward movement of the slide 4 relative to the base plate. Relative forward movement is possible, however.

L'ensemble des moyens qui viennent d'être décrits font que la glissière peut osciller dans la plaque de base autour d'un axe horizontal et transversal situé approximativement à l'arrière de la glissière, sur une faible amplitude.All the means which have just been described mean that the slide can oscillate in the plate basic around a horizontal and transverse axis located approximately at the rear of the slide, on a low amplitude.

La partie avant présente donc une mobilité relativement au ski, qui est orientée selon une direction approximativement verticale.The front part therefore has mobility relative to the ski, which is oriented in a direction approximately vertical.

Par contre, la partie arrière de la glissière ne peut pas osciller pour un mouvement de roulis, car elle est maintenue sans jeu entre le fond et les rebords de la plaque de base.On the other hand, the rear part of the slide cannot oscillate for a rolling movement, because it is kept without play between the bottom and the edges of the base plate.

Naturellement, tout autre moyen approprié convient pour assurer cette liaison, notamment une goupille transversale reliant les parties arrière de la glissière et de la plaque de base.Naturally, any other suitable means is suitable for ensuring this connection, in particular a transverse pin connecting the rear parts of the slide and the base plate.

Le mouvement vers le haut de la glissière est limité par les rebords 15 et 16.The upward movement of the slide is limited by the edges 15 and 16.

Vers le bas, la glissière repose sur un bloc de matériau élastiquement déformable schématisé en 22. Ce bloc présente éventuellement des propriétés amortissantes. Il pourrait être remplacé ou assisté par tout moyen déformable approprié, notamment un ressort, un amortisseur, ou autre.Downwards, the slide rests on a block of elastically deformable material shown diagrammatically at 22. This block possibly has damping properties. He could be replaced or assisted by any suitable deformable means, in particular a spring, a shock absorber, or the like.

Le bloc 22 présente une épaisseur prévue pour maintenir au repos l'avant de la glissière dans sa position haute, ou à proximité de cette position. Le bloc 22 permet aussi, par son élasticité, de rattraper les jeux de fonctionnement dus aux tolérances de fabrication des pièces. Sa raideur est prévue pour qu'il se comprime sous l'action du poids du skieur et des sollicitations verticales transitant à ce niveau entre la chaussure et le ski.The block 22 has a thickness provided to keep the front of the slide at rest in its high position, or close to this position. The block 22 also allows, by its elasticity, to make up for the operating clearances due to the manufacturing tolerances of the parts. Its stiffness is designed so that it compresses under the action of the skier's weight and the vertical stresses passing through at this level between the boot and the ski.

L'élément de fixation 1 peut être associé à tout frein de ski approprié. Notamment, le frein peut avoir comme palier l'avant de la plaque de base 11. Il peut aussi avoir un palier indépendant rapporté à l'avant de la plaque de base et fixé au ski avec elle. The fastening element 1 can be associated with any suitable ski brake. In particular, the brake can have as a bearing the front of the base plate 11. It can also have an independent bearing relative to the front of the baseplate and attached to the ski with it.

L'élément de fixation fonctionne de la façon suivante. L'arrière de la chaussure est relié au ski par l'intermédiaire du bloc 22 qui se comprime avec l'abaissement de la plaque de support 9 relativement au ski. Ainsi, au cours de la pratique du ski, les chocs et secousses du ski sont transmis à la chaussure selon une direction verticale via le bloc 22 qui réalise un filtrage ou un amortissement selon sa dureté. L'arrière de la chaussure est en quelque sorte monté sur une suspension qui opère selon une direction verticale. La liaison entre la glissière et la plaque de base s'oppose par ailleurs à un mouvement relatif au roulis de ces deux éléments.The fastener works as follows. The back of the boot is connected to the ski by through the block 22 which compresses with the lowering of the support plate 9 relatively skiing. Thus, during skiing, shocks and jolts from the ski are transmitted to the shoe in a vertical direction via block 22 which performs filtering or cushioning according to its hardness. The back of the shoe is somehow mounted on a suspension which operates according to a vertical direction. The connection between the slide and the base plate also prevents a movement relative to the roll of these two elements.

Selon l'invention, l'élément de fixation 1 présente un moyen anti-roulis additionnel situé vers l'avant de la glissière.According to the invention, the fastening element 1 has a additional anti-roll means located towards the front of the slide.

Dans le mode de réalisation illustré dans les figures, le moyen anti-roulis comprend une large biellette 25 reliée à la plaque de base 11 et à la glissière 4 par une articulation autour d'un axe horizontal et transversal.In the embodiment illustrated in the figures, the anti-roll means comprises a large rod 25 connected to the base plate 11 and to the slide 4 by an articulation around an axis horizontal and transverse.

La biellette 25 présente une largeur voisine de la largeur de la glissière 4. Ainsi que le montre la figure 3, la biellette peut être réalisée à partir d'un profilé plat dont les deux bouts latéraux sont repliés pour former les flancs. En outre, sa rigidité en torsion peut être renforcée par un repli transversal 26 formant une nervure. Naturellement, tout autre construction appropriée de la biellette convient. Par exemple, la biellette pourrait être réalisée à partir d'un fil d'acier replié en un large "U".The link 25 has a width close to the width of the slide 4. As shown in the Figure 3, the link can be made from a flat profile whose two side ends are folded back to form the sides. In addition, its torsional rigidity can be reinforced by a fold transverse 26 forming a rib. Naturally, any other suitable construction of the link agrees. For example, the link could be made from a steel wire folded into a wide "U".

La biellette 25 est percée d'orifice qui définissent deux logements 28 et 29 pour des axes d'articulation 30 et 31. Les axes 30 et 31 sont parallèles entre eux et sont disposés sensiblement dans un plan horizontal. Les extrémités de l'axe 30 sont portés par la plaque de base 11, plus précisément par ses ailes 13 et 14.The link 25 is pierced with orifice which define two housings 28 and 29 for axes articulation 30 and 31. The axes 30 and 31 are mutually parallel and are arranged substantially in a horizontal plane. The ends of the axis 30 are carried by the base plate 11, more precisely by its wings 13 and 14.

L'axe 31 est situé en arrière de l'axe 30. Selon les figures, la glissière présente sur l'avant deux pattes 34 et 35 repliées pour que leur extrémité viennent reposer sur l'axe 31. Les pattes 34 et 35 sont largement écartées l'une de l'autre.The axis 31 is located behind the axis 30. According to the figures, the slide has two fronts legs 34 and 35 folded so that their ends come to rest on the axis 31. Legs 34 and 35 are widely separated from each other.

La plaque de support 9 qui est montée coulissante le long de la glissière est engagée sur l'avant jusqu'à ce quelle vienne en butée contre les pattes 34 et 35. Dans cette position, les nervures 37, qu'elle présente à sa face inférieure, font saillie entre les pattes. Ces nervures présentent un orifice transversal 38 situé dans le prolongement de l'intérieur du pli que présentent les pattes 34 et 35, qui est traversé par l'axe 31. On réalise ainsi une liaison par appui de la glissière sur l'axe 31, avec verrouillage par la coopération entre l'axe et la plaque de support 9. Naturellement toute autre liaison appropriée convient.The support plate 9 which is slidably mounted along the slide is engaged on the front until it comes into abutment against the legs 34 and 35. In this position, the ribs 37, that it has on its underside, protrude between the legs. These ribs have an orifice transverse 38 located in the extension of the interior of the fold which have the tabs 34 and 35, which is crossed by the axis 31. A connection is thus produced by pressing the slide on the axis 31, with locking by the cooperation between the axis and the support plate 9. Naturally any other connection appropriate is suitable.

La biellette 25 n'a qu'un degré de liberté en rotation autour de l'axe 30 par rapport à la plaque de base, et autour de l'axe 31 par rapport à la glissière.The link 25 has only one degree of freedom in rotation about the axis 30 relative to the plate base, and around the axis 31 relative to the slide.

La biellette empêche l'avant de la glissière d'avoir un mouvement de roulis. Par contre, la biellette n'oppose aucune résistance aux mouvements verticaux de l'avant de la glissière, ces mouvements provoquent la compression du bloc 22.The link prevents the front of the slide from rolling. However, the link offers no resistance to vertical movements from the front of the slide, these movements cause compression of block 22.

Les sollicitations verticales entre la chaussure et le ski sont donc amorties ou filtrées, mais les sollicitations de roulis transitent entre la chaussure et le ski sans solliciter au roulis le bloc 22. On obtient un amortissement des sollicitations verticales sans nuire aux conditions de conduite du ski. The vertical stresses between the boot and the ski are therefore damped or filtered, but the rolling stresses pass between the boot and the ski without stressing the rolling block 22. obtains a damping of the vertical stresses without harming the conditions of driving of the ski.

On peut remarquer qu'au cours des mouvements verticaux de l'avant de la glissière, la biellette et la glissière suivent des trajectoires divergeantes. Les mouvements de ces éléments présentent une composante horizontale dont l'amplitude est cependant faible.We can notice that during the vertical movements of the front of the slide, the link and the slide follows divergent paths. The movements of these elements present a horizontal component whose amplitude is however small.

Pour permettre ce mouvement relatif de composante horizontale, on prévoit que la composante horizontale du mouvement relatif entre la biellette et la glissière entraíne la glissière vers l'avant. La liaison entre la glissière et la plaque de base autorise en effet un tel mouvement. Ce mouvement comprime par ailleurs le ressort de recul 6, étant donné que le corps de la fixation est retenu par la chaussure. Le ressort de recul tend à ramener élastiquement la glissière vers l'arrière.To allow this relative movement of the horizontal component, it is expected that the component horizontal relative movement between the rod and the slide causes the slide forward. The connection between the slide and the base plate indeed allows such a movement. This movement also compresses the recoil spring 6, since the body of the binding is retained by the shoe. The recoil spring tends to bring the slide back elastically.

Selon cette construction, lors d'une forte pression de la chaussure sur le ski, la plaque de support 9 s'abaisse, provoquant la rotation de la biellette et de la glissière, ainsi qu'un mouvement vers l'avant de la glissière. Ce mouvement crée une compression additionnelle du ressort de recul.According to this construction, during strong pressure of the boot on the ski, the support plate 9 lowers, causing the link and slide to rotate, as well as forward movement of the slide. This movement creates additional compression of the recoil spring.

Selon une autre variante visible en figure 4, l'un des logements de la biellette, en l'occurrence le logement 29' est oblong. L'oblong est orienté selon un plan horizontal, pour interdire un mouvement de roulis de l'axe 30.According to another variant visible in FIG. 4, one of the housings of the link, in this case the housing 29 'is oblong. The oblong is oriented in a horizontal plane, to prevent movement of axis 30 roll.

En variante, l'un des autres orifices traversé par les axes 30 et 31 pourrait être oblong.As a variant, one of the other orifices crossed by the axes 30 and 31 could be oblong.

Le dispositif selon l'invention qui a été décrit peut être adapté à d'autres constructions, et notamment celles décrites dans demandes de brevet français publiées sous les numéros 2 680 697, 2 684 885, 2 687 325, au nom de la demanderesse.The device according to the invention which has been described can be adapted to other constructions, and in particular those described in French patent applications published under the numbers 2 680 697, 2 684 885, 2 687,325, on behalf of the plaintiff.
