Abstract

The invention relates to an intermediate (interface) device between a ski and the bindings for holding a boot on the ski. The device comprises two stops (14, 15) intended to be connected to the ski, towards the front and the rear of the central part of the base of the ski, respectively, and a linking leg (18, 52) forming a stiffener between the two stops. The linking leg comprises at least two levers (20, 10, 54, 53), connected by at least one link forming a central articulation. One of the bearing plates of the boot is movable vertically and transmits the vertical stresses from the boot to one of the levers, and an elastic return means (40, 60) exerts, on one of the levers (10, 53), an upward return force of sufficient intensity to hold the central articulation of the two levers suspended in the presence of the boot. The link between the levers can preferably be disengaged. <IMAGE>

Description

L'invention concerne un dispositif interface visant à modifier la répartition naturelle d'un ski sur sa surface de glisse.The invention relates to an interface device aimed at modifying the natural distribution of a ski on its sliding surface.

Les skis qui sont utilisés pour la pratique du ski alpin sont constitués par des planches relativement longues, sur lesquelles les chaussures du skieur sont retenues par des éléments de fixation avant et arrière. Les chaussures et les éléments de fixation se trouvent approximativement dans la zone médiane du ski. Les skis présentent en eux-mêmes, au repos, une cambrure naturelle, par lequel la zone médiane est surélevée naturellement par rapport à l'extrémité avant du ski, ou spatule, et l'extrémité arrière du ski, ou talon. En outre, les skis présentent une flexibilité, qui tient à leur structure interne. Lors de la pratique du ski, le ski se déforme de manière élastique en réponse aux différentes sollicitations auxquelles il est soumis de la part du skieur, mais aussi de la part du terrain sur lequel il glisse.The skis which are used for the practice of alpine skiing consist of relatively long boards, on which the skier's shoes are retained by front and rear fastening elements. The boots and binding elements are located approximately in the middle area of the ski. The skis have in themselves, at rest, a natural camber, by which the middle zone is raised naturally with respect to the front end of the ski, or tip, and the rear end of the ski, or heel. In addition, the skis have flexibility, which is due to their internal structure. During skiing, the ski deforms elastically in response to the various stresses to which it is subjected on the part of the skier, but also on the part of the terrain on which it slides.

Il existe des dispositifs interfaces qui sont interposés entre les éléments de fixation et le ski. De tels interfaces sont par exemple connus d'après les demandes de brevet publiées sous les numéros WO 83/03360, EP 492 658, EP 409 749. Ces dispositifs modifient la flexibilité de la poutre du ski, en la raidissant, ou bien avec un effet d'amortissement. Cependant, ces dispositifs agissent de façon passive, c'est-à-dire qu'ils ne font que réagir à une flexion déterminée du ski.There are interface devices which are interposed between the binding elements and the ski. Such interfaces are for example known from patent applications published under the numbers WO 83/03360, EP 492 658, EP 409 749. These devices modify the flexibility of the ski beam, by stiffening it, or else with a damping effect. However, these devices act passively, that is to say that they only react to a determined flexion of the ski.

Un autre dispositif de ce type est connu d'après la demande de brevet français publiée sous le numéro FR 2 689 775. Ce dispositif comprend une poutre longitudinale surélevée par rapport au ski. L'extrémité arrière de la poutre est solidaire du ski, et son extrémité avant est reliée par un bloc de matériau amortissant qui est sollicité au cisaillement. Ce dispositif amortit les déformations en flexion du ski. Il amortit aussi la chaussure de façon verticale. Mais cet amortissement est relativement raide à cause de la structure rigide de la poutre.Another device of this type is known from the French patent application published under the number FR 2 689 775. This device comprises a longitudinal beam raised relative to the ski. The rear end of the beam is integral with the ski, and its front end is connected by a block of damping material which is stressed during shearing. This device absorbs the flexural deformations of the ski. It also absorbs the shoe vertically. But this damping is relatively steep because of the rigid structure of the beam.

On connaît également d'après la demande de brevet européen publiée sous le numéro EP 530 449 au nom de la demanderesse un dispositif interface qui modifie de façon dynamique la répartition de pression du ski sur la neige, en fonction des sollicitations verticales que le skieur exerce sur ses skis. Ce dispositif comprend un palpeur mobile verticalement qui transmet à l'embase de l'élément de fixation avant les sollicitations verticales qu'il capte en provenance de la chaussure. Dans l'un des modes de réalisation, ces sollicitations sont transmises par l'intermédiaire d'un basculeur et d'une plaque de liaison sensiblement horizontale articulée d'un côté au basculeur et de l'autre à l'embase de la fixation.Also known from the European patent application published under the number EP 530 449 in the name of the applicant an interface device which dynamically modifies the pressure distribution of the ski on the snow, as a function of the vertical stresses which the skier exerts on his skis. This device comprises a vertically movable feeler which transmits to the base of the fastening element before the vertical stresses which it picks up from the shoe. In one of the embodiments, these stresses are transmitted via a rocker and a substantially horizontal connecting plate articulated on one side to the rocker and on the other to the base of the binding.

Selon un perfectionnement apporté par la demanderesse, la plaque de liaison est construite comme une genouillère qui est refermée par la chaussure et qui s'ouvre d'elle-même dès que la chaussure est libérée.According to an improvement brought by the applicant, the connecting plate is constructed like a toggle which is closed by the shoe and which opens by itself as soon as the shoe is released.

Un autre perfectionnement de ce dispositif a consisté à interposer entre le basculeur et l'embase de l'élément de fixation un ou plusieurs ressorts précontraints qui absorbent les sollicitations excessives que le palpeur transmet à l'embase. En se cassant, la genouillère élimine la réaction que cette précontrainte induit dans le ski dès que la chaussure est libérée de ses éléments de fixation qui la retiennent.Another improvement of this device consisted in interposing between the rocker and the base of the fastening element one or more preloaded springs which absorb the excessive stresses which the probe transmits to the base. By breaking, the knee brace eliminates the reaction that this prestressing induces in the ski as soon as the boot is released from its fastening elements which hold it.

On a recherché à simplifier la structure de ce dispositif interface qui est relativement complexe notamment à cause de la présence du basculeur et de son environnement, en obtenant des qualités d'amortissement vertical meilleures que celles du dispositif selon la demande de brevet FR 2 689 775.We sought to simplify the structure of this interface device which is relatively complex in particular because of the presence of the rocker and its environment, by obtaining better vertical damping qualities than those of the device according to patent application FR 2 689 775. .

Ainsi, la présente invention propose un dispositif interface qui influence la répartition de pression du ski sur la neige, et dont la structure est simplifiée par rapport aux dispositifs existants.Thus, the present invention provides an interface device which influences the pressure distribution of the ski on the snow, and whose structure is simplified compared to existing devices.

Un autre but de l'invention est de proposer un dispositif interface qui présente des caractéristiques d'amortissement vertical et longitudinal élevées dans la transmission des sollicitations entre le ski et la chaussure.Another object of the invention is to provide an interface device which has high vertical and longitudinal damping characteristics in the transmission of stresses between the ski and the boot.

Selon une première caractéristique de l'invention, l'interface est construit comme une jambe de liaison s'étendant entre deux butées reliées au ski. La jambe de liaison présente au moins deux leviers articulés entre eux, et la liaison centrale entre les leviers est maintenue suspendue au dessus du ski.According to a first characteristic of the invention, the interface is constructed as a connecting leg extending between two stops connected to the ski. The connecting leg has at least two levers hinged together, and the central connection between the levers is kept suspended above the ski.

Ce mode de construction permet d'obtenir des caractéristiques dynamiques de raidissement longitudinal du ski et d'amortissement vertical de la chaussure, sans avoir recours à une transmission des efforts au moyen d'un basculeur. Les efforts transmis peuvent cependant présenter une intensité élevée, étant donné que la jambe de liaison se présente comme une sorte de genouillère articulée dans sa partie centrale.This construction method makes it possible to obtain dynamic characteristics of longitudinal stiffening of the ski and vertical damping of the boot, without having to resort to a transmission of forces by means of a rocker. The transmitted forces can however have a high intensity, since the connecting leg is presented as a kind of knee joint articulated in its central part.

Selon une autre caractéristique de l'invention, un élément compressible intercalé entre le ski et l'un des leviers de la jambe de liaison exerce sur le lever en question un effort vertical vers le haut, de façon à maintenir suspendue l'articulation centrale. De plus, cet élément compressible transmet localement au ski une partie des efforts verticaux en provenance de la chaussure. Cet élément compressible peut aussi présenter des caractéristiques amortissantes ou viscoélastiques, et de ce fait contribuer à l'amortissement vertical de la chaussure. Cet amortissement se trouve amélioré du fait que la jambe de liaison est construite en deux leviers articulés.According to another characteristic of the invention, a compressible element interposed between the ski and one of the levers of the connecting leg exerts on the lever in question a vertical upward force, so as to keep the central articulation suspended. In addition, this compressible element locally transmits part of the vertical forces from the boot to the ski. This compressible element can also have damping or viscoelastic characteristics, and thereby contribute to the vertical damping of the shoe. This damping is improved by the fact that the connecting leg is constructed in two articulated levers.

Selon une autre caractéristique de l'invention, la liaison centrale entre les leviers est débrayable, ce qui permet de rendre l'interface inactif de façon momentanée. Avantageusement, c'est la pédale d'actionnement du frein de ski qui commande également ce débrayage, si bien que l'interface n'est réellement actif qu'en présence de la chaussure.According to another characteristic of the invention, the central link between the levers is disengageable, which makes the interface temporarily inactive. Advantageously, it is the ski brake actuation pedal which also controls this declutching, so that the interface is only really active in the presence of the boot.

Selon une autre caractéristique de l'invention, la longueur de la jambe de liaison est légèrement supérieure à la distance entre les deux butées, si bien que l'interface exerce au repos une précontrainte sur le ski.According to another characteristic of the invention, the length of the connecting leg is slightly greater than the distance between the two stops, so that the interface exerts a prestress on the ski at rest.

Selon une autre caractéristique de l'invention, l'une des butées d'appui de la jambe de liaison est mobile selon une direction longitudinale, et elle est rappelée de façon élastique vers l'autre butée. Ceci permet avantageusement de limiter l'action de l'interface sur le ski, lors de sollicitations extrêmement fortes de la chaussure en direction du ski. Egalement, ceci permet de limiter la remontée vers la chaussure des déformations de la partie avant du ski qui sont dues au fléchissement du ski, par exemple sur une bosse.According to another characteristic of the invention, one of the support stops of the connecting leg is movable in a longitudinal direction, and it is returned elastically towards the other stop. This advantageously makes it possible to limit the action of the interface on the ski, during extremely strong stresses on the boot in the direction of the ski. Also, this makes it possible to limit the ascent towards the boot of deformations of the front part of the ski which are due to the flexing of the ski, for example on a bump.

Selon une autre caractéristique, le levier arrière est la glissière de l'élément de fixation arrière. Ceci permet de rendre l'extrémité arrière de la chaussure mobile verticalement pour activer l'interface, sans pour autant solliciter le mécanisme d'ouverture de la mâchoire.According to another characteristic, the rear lever is the slide of the rear fixing element. This makes the rear end of the shoe movable vertically to activate the interface, without requiring the jaw opening mechanism.

Selon une autre caractéristique de l'invention, on ajuste la position au repos de l'articulation centrale de la jambe de liaison par rapport à ses deux extrémités, pour qu'une sollicitation verticale de la chaussure sur l'interface ait un effet plus ou moins prononcé sur la répartition de pression du ski sur la neige.According to another characteristic of the invention, the position at rest of the central articulation of the connecting leg is adjusted relative to its two ends, so that a vertical stress on the shoe on the interface has a more or less effect. less pronounced on the pressure distribution of the ski on the snow.

La figure 9 est une vue semblable à la figure 8 du dispositif en présence de la chaussure.Figure 9 is a view similar to Figure 8 of the device in the presence of the shoe.

La figure 1 représente un ski 1, vu de côté dans sa zone centrale. Des éléments de fixation 3 et 4 sont montés sur le ski dans cette zone centrale.FIG. 1 represents a ski 1, seen from the side in its central zone. Fastening elements 3 and 4 are mounted on the ski in this central area.

Les éléments de fixation 3 et 4 sont de tout type approprié. L'élément de fixation avant 3 présente de façon connue une mâchoire 5 de retenue de l'extrémité avant de la chaussure. La mâchoire est portée par un corps 6, et le corps est lui-même monté sur une plaque de base 7 par laquelle l'élément de fixation est assemblé au ski.The fastening elements 3 and 4 are of any suitable type. The front fastening element 3 has in known manner a jaw 5 for retaining the front end of the shoe. The jaw is carried by a body 6, and the body is itself mounted on a base plate 7 by which the binding element is assembled to the ski.

De façon semblable, l'élément de fixation arrière 4 présente une mâchoire 8 portée par un corps 9. Le corps 9 est monté coulissant le long d'une plaque de base 10 conformée en glissière orientée selon la direction longitudinale du ski, sous l'action d'un ressort appelé ressort de recul qui repousse élastiquement le corps vers l'avant.Similarly, the rear fixing element 4 has a jaw 8 carried by a body 9. The body 9 is slidably mounted along a base plate 10 shaped as a slide oriented in the longitudinal direction of the ski, under the action of a spring called recoil spring which elastically pushes the body forward.

A chaque élément de fixation 3, 4 est également associé une plaque d'appui 12, 13 sur laquelle repose la semelle de chaussure, mais ces plaques d'appui seront décrites plus en détail ultérieurement.Each fastening element 3, 4 is also associated with a support plate 12, 13 on which the shoe sole rests, but these support plates will be described in more detail later.

Le dispositif interface qui fait l'objet de la présente invention est situé dans la zone centrale du ski.The interface device which is the subject of the present invention is located in the central area of the ski.

Il présente une butée avant et une butée arrière reliées solidairement au ski.It has a front stop and a rear stop connected integrally to the ski.

Avantageusement, ainsi que le schématise les figures, la butée avant 14 est une embase solidarisée au ski par tout moyen approprié, par exemple des vis, présentant à sa surface supérieure une zone de montage destinée à recevoir la plaque de base 7 de l'élément avant de fixation.Advantageously, as shown in the figures, the front stop 14 is a base secured to the ski by any suitable means, for example screws, having on its upper surface a mounting zone intended to receive the base plate 7 of the element before fixing.

De même, la butée arrière 15 est formée par une embase qui est solidarisée au ski par tout moyen approprié par exemple par des vis. L'embase 15 s'étend sous la plaque de base 10 de l'élément de fixation arrière, et elle est équipée de moyens pour recevoir la plaque de base 10 de l'élément de fixation arrière 4. Ces moyens seront décrits plus en détail ultérieurement.Similarly, the rear stop 15 is formed by a base which is secured to the ski by any suitable means, for example by screws. The base 15 extends under the base plate 10 of the rear fixing element, and it is equipped with means for receiving the base plate 10 of the rear fixing element 4. These means will be described in more detail later.

Une jambe de liaison 18 articulée relie ces deux butées 14 et 15. La jambe de liaison est maintenue en position surélevée par rapport à la surface supérieure du ski.An articulated connecting leg 18 connects these two stops 14 and 15. The connecting leg is held in an elevated position relative to the upper surface of the ski.

Dans l'exemple illustré, la jambe de liaison 18 comprend deux leviers, un lever avant et un lever arrière, chacun relié à une butée avant et arrière. Les deux leviers sont de nature incompressible.In the example illustrated, the connecting leg 18 comprises two levers, a front lever and a rear lever, each connected to a front and rear stop. The two levers are incompressible in nature.

Ainsi, en se reportant aux figures, la jambe de liaison présente un levier avant 20 constitué par une sorte de poutre longiligne qui est reliée dans sa partie avant à la butée avant 14 par une liaison permettant un pivotement d'amplitude limitée. La figure 1 représente le lever avant 20 dans sa position haute. Dans sa position basse schématisée en figure 6, le lever avant 20 est parallèle à la surface supérieure du ski, en étant surélevé par rapport à la surface supérieure du ski.Thus, referring to the figures, the connecting leg has a front lever 20 constituted by a kind of elongated beam which is connected in its front part to the front stop 14 by a link allowing a pivoting of limited amplitude. Figure 1 shows the lift before 20 in its upper position. In its low position shown diagrammatically in FIG. 6, the front lift 20 is parallel to the upper surface of the ski, being raised relative to the upper surface of the ski.

La liaison entre le lever 20 et l'embase avant est de tout type approprié, notamment par un axe transversal, par coopération de formes complémentaires, ou autre.The connection between the lever 20 and the front base is of any suitable type, in particular by a transverse axis, by cooperation of complementary shapes, or other.

La figure 3 illustre un mode préférentiel de réalisation de cette liaison. Selon ce mode de réalisation, la butée avant 14, c'est-à-dire l'embase qui porte la plaque de base de l'élément de fixation, présente dans sa partie arrière un évidement 21 ouvert vers le haut et vers l'arrière. Dans cet évidement, un bloc 22 de matériau élastiquement déformable est logé, de façon à combler au moins la partie avant de l'évidement. Le bloc est en toute matière appropriée, et peut présenter des propriétés amortissantes ou viscoélastiques.Figure 3 illustrates a preferred embodiment of this connection. According to this embodiment, the front stop 14, that is to say the base which carries the base plate of the fixing element, has in its rear part a recess 21 open upwards and towards the back. In this recess, a block 22 of elastically deformable material is housed, so as to fill at least the front part of the recess. The block is of any suitable material, and may have damping or viscoelastic properties.

L'extrémité avant 23 du levier 20 présente une section réduite aux dimensions de l'évidement 21, de façon à pouvoir coulisser librement dans le volume de l'évidement et comprimer le cas échéant le bloc 22. La face avant de l'extrémité 23 est dressée pour comprimer le bloc 22 en se déplaçant vers l'avant relativement à l'embase 14.The front end 23 of the lever 20 has a section reduced to the dimensions of the recess 21, so that it can slide freely in the volume of the recess and compress if necessary the block 22. The front face of the end 23 is erected to compress the block 22 by moving forward relative to the base 14.

La liaison entre le lever 20 et l'embase 14 est couverte par un capot 24 réalisée en une matière élastiquement déformable. Avantageusement, le capot 24 présente latéralement deux pattes 25 et 26, qui descendent le long des faces latérales de l'embase 14 et s'emboîtent dans des dégagements de forme correspondante.The connection between the lever 20 and the base 14 is covered by a cover 24 made of an elastically deformable material. Advantageously, the cover 24 has laterally two legs 25 and 26, which descend along the lateral faces of the base 14 and fit into recesses of corresponding shape.

Vers l'arrière, le capot 24 présente une languette 28 qui recouvre la partie avant 23 du lever 20.Towards the rear, the cover 24 has a tongue 28 which covers the front part 23 of the lever 20.

La languette présente vers son extrémité arrière un plot 29 qui coopère avec une ouverture 30 du lever 20, en forme de boutonnière. Le plot 29 peut coulisser longitudinalement dans la boutonnière 30 sur une amplitude limitée. Ces moyens assurent l'accrochage du lever 20 à l'embase 14. La languette réagit en outre comme une charnière et permet un mouvement de rotation du lever 20.The tongue has towards its rear end a stud 29 which cooperates with an opening 30 of the lever 20, in the form of a buttonhole. The stud 29 can slide longitudinally in the buttonhole 30 over a limited amplitude. These means ensure that the lever 20 is hooked to the base 14. The tongue also reacts like a hinge and allows the lever 20 to rotate.

Eventuellement, une goupille transversale 27 assure la liaison mobile entre le levier 20 et l'embase 14.Optionally, a transverse pin 27 ensures the mobile connection between the lever 20 and the base 14.

Ainsi, le lever peut pivoter d'un position haute à une position basse. En outre, dans la position basse du lever, un mouvement relatif entre l'embase 14 et le levier 20 peut se produire selon une direction longitudinale. Ce mouvement comprime le bloc 22 qui, en se déformant, s'oppose à ce mouvement.Thus, the lift can pivot from a high position to a low position. In addition, in the low position of the lever, a relative movement between the base 14 and the lever 20 can occur according to a longitudinal direction. This movement compresses the block 22 which, by deforming, opposes this movement.

De préférence, la plaque d'appui 12 qui supporte l'extrémité avant de la semelle de chaussure est associée au capot 24. Par exemple, comme le représente la figure 5, la plaque d'appui 12 est la partie supérieure d'un élément d'appui transversal 31 qui repose sur l'embase 14, de chaque côté de l'évidement 21, et qui traverse une ouverture 32 du capot 24, de telle façon que la plaque d'appui 12 soit en saillie au dessus du capot 24.Preferably, the support plate 12 which supports the front end of the shoe sole is associated with the cover 24. For example, as shown in FIG. 5, the support plate 12 is the upper part of an element transverse support 31 which rests on the base 14, on each side of the recess 21, and which passes through an opening 32 of the cover 24, so that the support plate 12 protrudes above the cover 24 .

La figure 4 illustre une variante de réalisation du lever 20. Selon cette variante, le lever est en deux parties 20a et 20b qui sont assemblées par des moyens permettant d'ajuster la longueur globale du lever. Par exemple, les extrémités des parties 20a et 20b sont prévues pour coulisser l'une relativement à l'autre selon une direction longitudinale, et un boulon d'assemblage 34 traverse l'ensemble au niveau d'un orifice de la partie 20a et d'une lumière longitudinale de la partie 20b.FIG. 4 illustrates an alternative embodiment of the lever 20. According to this variant, the lever is in two parts 20a and 20b which are assembled by means making it possible to adjust the overall length of the lever. For example, the ends of the parts 20a and 20b are provided to slide relative to each other in a longitudinal direction, and an assembly bolt 34 passes through the assembly at an orifice of the part 20a and d 'a longitudinal light of part 20b.

Le dispositif selon l'invention comprend par ailleurs un lever arrière qui est articulé à la butée arrière. Dans le mode de réalisation illustré, le levier arrière est la plaque de base 10 qui forme la glissière de l'élément de fixation arrière 4. La plaque de base est reliée à l'embase 15 dans sa partie arrière par des moyens de liaison qui assurent une retenue selon une direction longitudinale, qui permettent en outre une oscillation de haut en bas tout en entravant un mouvement de roulis de la plaque de base relativement à l'embase. Dans la figure 1, ces moyens sont représentés sous la forme de deux pattes 35 qui forment un prolongement vers l'arrière de la plaque de base 10, et qui sont engagés dans des logements de dimensions correspondante que présente le rebord arrière 36 de l'embase.The device according to the invention also comprises a rear lever which is articulated to the rear stop. In the illustrated embodiment, the rear lever is the base plate 10 which forms the slide of the rear fixing element 4. The base plate is connected to the base 15 in its rear part by connecting means which provide a retention in a longitudinal direction, which also allow an oscillation from top to bottom while hampering a rolling movement of the base plate relative to the base. In FIG. 1, these means are represented in the form of two tabs 35 which form a rearward extension of the base plate 10, and which are engaged in housings of corresponding size which the rear edge 36 of the base.

Naturellement, tout autre moyen approprié convient, par exemple un axe d'articulation transversal qui relie la plaque de base et l'embase. Le fait d'entraver les mouvements relatifs de roulis entre la plaque de base et l'embase est avantageux pour assurer une bonne transmission des efforts et sollicitations latérales qui transitent entre le ski et la chaussure.Naturally, any other suitable means is suitable, for example a transverse articulation axis which connects the base plate and the base. Obstructing the relative roll movements between the base plate and the base is advantageous for ensuring good transmission of the forces and lateral stresses which pass between the ski and the boot.

La plaque de base 10 est par ailleurs maintenue relevée par rapport à la surface supérieure du ski, ou plus précisément par rapport à l'embase 15, par un moyen de rappel élastique qui développe sur cet élément un moment de rappel vers le haut d'intensité suffisante pour maintenir la plaque de base 10 à l'état suspendu en présence de la chaussure, et de préférence même dans le cas de sollicitations vers le bas exercée par la chaussure sur ses appuis.The base plate 10 is also kept raised relative to the upper surface of the ski, or more precisely relative to the base 15, by an elastic return means which develops on this element a moment of return upwards. sufficient intensity to maintain the base plate 10 in the suspended state in the presence of the shoe, and preferably even in the case of downward stresses exerted by the shoe on its supports.

Ce moyen de rappel élastique relie la plaque de base et le ski, par exemple par l'intermédiaire de l'embase 15. Il assure l'amortissement des sollicitations qui transitent entre la chaussure. En outre, il localise la zone du ski qui est sollicitée pour la réaction à une sollicitation du moyen de rappel élastique. Il influe donc sur la répartition de pression du ski sur la neige.This elastic return means connects the base plate and the ski, for example by means of the base 15. It absorbs the stresses which pass between the boot. In addition, it locates the area of the ski which is stressed for the reaction to a stress from the elastic return means. It therefore influences the pressure distribution of the ski on the snow.

Dans le mode de réalisation illustré, le moyen de rappel élastique est un bloc 40 de matériau élastiquement compressible, qui présente des propriétés amortissantes, et de préférence viscoélastiques. Le bloc 40 est situé vers l'avant de la plaque de base 10, entre l'embase et la plaque de base. Il concentre dans cette zone les efforts verticaux que la chaussure transmet au ski.In the illustrated embodiment, the elastic return means is a block 40 of elastically compressible material, which has damping properties, and preferably viscoelastic properties. The block 40 is located towards the front of the base plate 10, between the base and the base plate. It concentrates in this area the vertical forces that the boot transmits to the ski.

Naturellement, tout autre moyen de rappel élastique peut convenir, par exemple un ressort de compression, ou un ressort de torsion.Naturally, any other elastic return means may be suitable, for example a compression spring, or a torsion spring.

De préférence, la plaque de base est retenue vers le haut par une butée. Dans les figures, cette butée est formée par des pattes latérales 41 de l'embase 15 qui remontent de chaque côté de la plaque de base 10, et qui présentent un repli vers l'intérieur.Preferably, the base plate is retained upward by a stop. In the figures, this stop is formed by lateral tabs 41 of the base 15 which rise on each side of the base plate 10, and which have an inward fold.

Les deux leviers 20 et 10 qui forment la jambe de force sont par ailleurs reliés à leur extrémité adjacente par une liaison. Cette liaison assure une transmission longitudinale des efforts d'un levier à l'autre, lorsque les leviers sont approximativement alignés. En outre, la liaison permet un mouvement angulaire relatif d'amplitude réduite entre les deux leviers.The two levers 20 and 10 which form the strut are also connected at their adjacent end by a link. This link ensures a longitudinal transmission of the forces from one lever to the other, when the levers are approximately aligned. In addition, the link allows a relative angular movement of reduced amplitude between the two levers.

De préférence, lorsque les deux leviers sont sensiblement dans l'alignement l'un de l'autre, la longueur de la jambe de liaison ainsi formée est légèrement supérieure à l'espace prévu entre les deux butées. Ceci induit dans la jambe de liaison une pré-contrainte, dont une partie est absorbée par la compression du bloc 22. De préférence également, la liaison entre les deux leviers est débrayable, et l'emboîtement ou le débrayage de la liaison est automatique avec l'engagement ou le dégagement de la chaussure, pour que cette pré-contrainte s'annule en l'absence de la chaussure.Preferably, when the two levers are substantially in alignment with one another, the length of the connecting leg thus formed is slightly greater than the space provided between the two stops. This induces a pre-stress in the connecting leg, part of which is absorbed by the compression of the block 22. Preferably also, the connection between the two levers is disengageable, and the interlocking or disengagement of the connection is automatic with engagement or disengagement of the shoe, so that this pre-stress is canceled in the absence of the shoe.

Dans le mode de réalisation illustré en figure 1, le lever avant 20, qui est articulé sur l'avant par une charnière élastique, présente une extrémité arrière qui peut s'emboîter sur l'extrémité avant du lever 10 et se déboîter.In the embodiment illustrated in FIG. 1, the front lever 20, which is articulated on the front by an elastic hinge, has a rear end which can be fitted on the front end of the lever 10 and disengage.

L'extrémité arrière du levier 20 est sollicitée vers le haut par un moyen de rappel élastique, dans le cas présent un bras de relevage escamotable 43.The rear end of the lever 20 is urged upwards by an elastic return means, in this case a retractable lifting arm 43.

Le levier avant 20 porte en outre vers son extrémité arrière la plaque d'appui 13 sur laquelle repose l'extrémité arrière de la semelle de chaussure.The front lever 20 further carries towards its rear end the support plate 13 on which the rear end of the shoe sole rests.

Les moyens d'emboîtement sont plus particulièrement visibles en figure 5. Ils comprennent pour l'extrémité arrière du levier 20 deux faces d'appui sensiblement perpendiculaires 44 et 45. Du côté du lever 10, les moyens d'emboîtement comprennent des faces d'appui complémentaires 46 et 47. De préférence, ces faces d'appui constituent l'extrémité avant d'une pièce de liaison 48 dont l'extrémité arrière est engagée dans le profilé de la glissière qui forme le levier 10.The interlocking means are more particularly visible in FIG. 5. They comprise, for the rear end of the lever 20, two substantially perpendicular bearing faces 44 and 45. On the side of the lever 10, the interlocking means comprise faces of complementary support 46 and 47. Preferably, these support faces constitute the front end of a connecting piece 48, the rear end of which is engaged in the profile of the slide which forms the lever 10.

Les faces 44 et 46 sont destinées à transmettre les efforts longitudinaux entre les deux leviers. Lorsque les leviers sont emboîtés, les faces 44 et 46 sont sensiblement verticales. De préférence, l'une des faces est légèrement bombée ou biseautée de façon à produire un rattrapage de jeu et une contrainte de compression lors de l'emboîtement.The faces 44 and 46 are intended to transmit the longitudinal forces between the two levers. When the levers are fitted, the faces 44 and 46 are substantially vertical. Preferably, one of the faces is slightly curved or bevelled so as to produce a play take-up and a compression stress during nesting.

Les faces 45 et 47 se recouvrent mutuellement et assurent la transmission verticale des sollicitations qui sont perçues par la plaque d'appui 13. Dans la figure 5, ces faces sont en deux parties, respectivement 45a, 45b, et 47a, 47b, situées de part et d'autre des surfaces 44 et 46.The faces 45 and 47 overlap each other and ensure the vertical transmission of the stresses which are perceived by the support plate 13. In FIG. 5, these faces are in two parts, respectively 45a, 45b, and 47a, 47b, located on either side of surfaces 44 and 46.

Le bras de relevage 43 est porté par la partie avant de l'embase 15. Il est articulé à cette embase autour d'un axe transversal, et sa partie supérieure circule dans un logement 42 qui est situé à la face inférieure du levier 20. Un ressort 49 assure par ailleurs le relevage élastique du bras 43.The lifting arm 43 is carried by the front part of the base 15. It is articulated to this base around a transverse axis, and its upper part circulates in a housing 42 which is located on the underside of the lever 20. A spring 49 also ensures the elastic lifting of the arm 43.

Avantageusement, le bras 43 constitue l'organe d'actionnement d'un frein de ski. Ainsi que cela est visible dans les figures, le bras 43 se prolonge vers l'arrière par deux bêches de freinage 50, qui passent de chaque côté du ski. Le ressort 49 est par ailleurs le ressort de rappel du frein de ski ainsi formé dans sa position active de freinage.Advantageously, the arm 43 constitutes the actuating member of a ski brake. As can be seen in the figures, the arm 43 is extended towards the rear by two braking spades 50, which pass on each side of the ski. The spring 49 is also the return spring of the ski brake thus formed in its active braking position.

Le fonctionnement du dispositif est le suivant. En partant de la position de repos qui est représentée dans la figure 1, l'engagement de la chaussure dans les éléments de fixation provoque l'appui de la semelle sur la plaque d'appui 13. Le lever 20 s'abaisse, et en s'abaissant il provoque l'escamotage du bras 43 et la rentrée des bêches de frein 50, contre la force de rappel du ressort 49. Le levier 20 s'abaisse jusqu'à son emboîtement avec le lever arrière 10. La jambe de liaison se trouve ainsi formée entre les deux butées ou embases 14 et 15. Cette configuration nominale du dispositif est illustrée dans la figure 6. L'articulation de la jambe de liaison est maintenue suspendue sous l'action du bloc 40 qui ne s'est comprimé que faiblement, seulement sous l'action du poids du skieur.The operation of the device is as follows. Starting from the rest position which is represented in FIG. 1, the engagement of the shoe in the fastening elements causes the support of the sole to rest on the support plate 13. The lever 20 is lowered, and in lowering it causes the retraction of the arm 43 and the retraction of the brake spades 50, against the return force of the spring 49. The lever 20 lowers until it engages with the rear lever 10. The connecting leg is thus formed between the two stops or bases 14 and 15. This nominal configuration of the device is illustrated in FIG. 6. The articulation of the connecting leg is kept suspended under the action of the block 40 which has not compressed only weakly, only under the action of the skier's weight.

Il faut souligner que de préférence, la jambe de liaison a légèrement comprimé le bloc compressible 22 situé à l'avant.It should be emphasized that preferably, the connecting leg has slightly compressed the compressible block 22 located at the front.

Au cours de la pratique du ski, le skieur transmet à la plaque d'appui 13 des sollicitations verticales vers le bas. Ces sollicitations sont diffusées dans les deux leviers et provoquent aussi la compression élastique du bloc 40 avec un effet de suspension élastique. Le bloc 40 transmet au ski les sollicitations verticales de la chaussure. La figure 7 illustre une telle sollicitation de la chaussure sur la jambe de liaison.During skiing, the skier transmits downward vertical stresses to the support plate 13. These stresses are diffused in the two levers and also cause the elastic compression of the block 40 with an elastic suspension effect. The block 40 transmits the vertical stresses of the boot to the ski. FIG. 7 illustrates such a stress on the shoe on the connecting leg.

Au cours de la pratique du ski, la jambe de liaison agit aussi comme un raidisseur longitudinal du ski. Le bloc avant 22 joue un rôle d'amortissement de ce raidisseur. En particulier, il amortit les flexions du ski qui sont provoquées par le relief que le ski rencontre. Il évite aussi que de telles flexions du ski remontent intégralement vers la jambe de liaison et vers la chaussure.During skiing, the connecting leg also acts as a longitudinal stiffener of the ski. The front unit 22 plays a damping role for this stiffener. In particular, it absorbs the flexions of the ski which are caused by the relief that the ski encounters. It also prevents such bending of the ski from going up fully towards the connecting leg and towards the boot.

De plus, selon la longueur relative des leviers par rapport à la distance entre les deux embases, et selon la hauteur relative de la liaison entre les deux leviers par rapport à la liaison des leviers aux embases, la jambe de liaison peut avoir sur les deux embases une action longitudinale plus ou moins prononcée.In addition, depending on the relative length of the levers in relation to the distance between the two bases, and according to the relative height of the connection between the two levers in relation to the connection of the levers to the bases, the connecting leg may have on both bases a more or less pronounced longitudinal action.

Par exemple, si, en position nominale, la liaison centrale est nettement surélevée par rapport aux liaisons des leviers aux embases, l'abaissement de la liaison produit une extension longitudinale de la jambe de liaison. Etant donné que les liaisons entre les leviers et les embases sont surélevées par rapport à la surface supérieure du ski, et donc par rapport à sa fibre neutre, l'extension de la jambe de force induit vers l'avant du ski et vers l'arrière un moment de flexion qui tend à faire plonger les extrémités du ski vers la neige. L'effet de l'extension de la jambe de liaison est en partie absorbé par la compression du bloc avant 22.For example, if, in the nominal position, the central link is clearly raised relative to the links of the levers to the bases, the lowering of the link produces a longitudinal extension of the link leg. Since the connections between the levers and the bases are raised relative to the upper surface of the ski, and therefore relative to its neutral fiber, the extension of the strut induced towards the front of the ski and towards the back a bending moment which tends to plunge the ends of the ski towards the snow. The effect of the extension of the connecting leg is partly absorbed by the compression of the front block 22.

Si, en position nominale, la liaison centrale se trouve sensiblement à la hauteur des liaisons entre les leviers et les embases, l'abaissement de la liaison centrale n'exerce sensiblement aucune action longitudinale sur les embases.If, in the nominal position, the central link is located substantially at the height of the links between the levers and the bases, the lowering of the central link has practically no longitudinal action on the bases.

Le bloc avant 22 conserve cependant un rôle d'amortissement en cas de flexion du ski.The front block 22, however, retains a damping role in the event of the ski flexing.

La liaison centrale peut aussi se trouver en position nominale en dessous du niveau des liaisons entre les leviers et les embases.The central link can also be in nominal position below the level of the links between the levers and the bases.

Lorsque la chaussure sort des éléments de fixation de façon accidentelle ou volontaire, le bras 43 déboîte le lever 20 et l'entraîne vers le haut. Parallèlement, les bêches de frein s'abaissent en position active de freinage.When the shoe emerges from the fastening elements accidentally or voluntarily, the arm 43 disengages the lever 20 and drives it upwards. At the same time, the brake spades are lowered to the active braking position.

Les figures 8 et 9 illustrent une variante de réalisation.Figures 8 and 9 illustrate an alternative embodiment.

Selon cette variante, la jambe de liaison 52 comprend un lever arrière 53, un levier avant 54, et un lever intermédiaire 55 qui assure une articulation centrale complexe de la jambe de liaison.According to this variant, the connecting leg 52 comprises a rear lever 53, a front lever 54, and an intermediate lever 55 which provides a complex central articulation of the connecting leg.

Le lever arrière est du même type que le lever 10 précédent. Le lever avant 54 est aussi du même type que le lever 20 précédent, excepté que son extrémité arrière est plus longue, et se termine par un patin 56 qui vient prendre appui directement sur l'extrémité avant du levier 53, selon une direction verticale.The rear lift is of the same type as the previous lift 10. The front lever 54 is also of the same type as the previous lever 20, except that its rear end is longer, and ends with a shoe 56 which comes to bear directly on the front end of the lever 53, in a vertical direction.

Le lever intermédiaire 55 est articulé à sa base au levier arrière 53, autour d'un axe transversal. Il est rappelé élastiquement vers le haut par un ressort 57. Sa partie avant coulisse dans un logement 58 que le levier avant présente à sa face inférieure. Le logement 58 présente dans sa partie avant une face d'appui verticale 59 contre laquelle, en présence de la chaussure, le lever intermédiaire prend appui selon une direction longitudinale ainsi que le représente la figure 9.The intermediate lever 55 is articulated at its base to the rear lever 53, around a transverse axis. It is spring-loaded upwards by a spring 57. Its front part slides in a housing 58 which the front lever has on its underside. The housing 58 has in its front part a vertical bearing face 59 against which, in the presence of the shoe, the intermediate lever is supported in a longitudinal direction as shown in FIG. 9.

Avantageusement, le levier 55 se prolonge vers l'arrière par deux bêches de freinage, de façon à former un dispositif de freinage pour le ski.Advantageously, the lever 55 is extended rearward by two braking spades, so as to form a braking device for skiing.

Un bloc élastiquement déformable 60 est situé entre le lever arrière 53 et le ski. Ce bloc exerce la même fonction que le bloc 40 précédent. De même, la liaison entre le lever avant et l'élément de fixation avant est du même type que dans le mode de réalisation précédent.An elastically deformable block 60 is located between the rear lever 53 and the ski. This block performs the same function as the previous block 40. Similarly, the connection between the front lever and the front fixing element is of the same type as in the previous embodiment.

Selon une direction verticale, les sollicitations de la chaussure sont captées par la plaque d'appui 13 située à l'arrière du lever 54, et transmises au lever arrière 53. Le bloc 60 assure une suspension élastique de la jambe de liaison.In a vertical direction, the stresses of the shoe are picked up by the support plate 13 located at the rear of the lever 54, and transmitted to the rear lever 53. The block 60 provides an elastic suspension of the connecting leg.

Selon une direction longitudinale, les sollicitations transitent entre les deux leviers avant et arrière va le lever intermédiaire. Cet élément supplémentaire permet une légère déformation de la jambe de liaison au cours de ses mouvements verticaux de suspension. De plus, l'ensemble de la jambe de liaison, y compris le frein, sont suspendus. Seul le bloc 60 assure sous le talon de la chaussure la transmission des efforts verticaux entre la chaussure et le ski. Il semble que cette construction améliore l'effet de suspension en lui donnant d'avantage de souplesse.In a longitudinal direction, the stresses pass between the two front and rear levers will the intermediate lift. This additional element allows a slight deformation of the connecting leg during its vertical suspension movements. In addition, the entire connecting leg, including the brake, is suspended. Only the block 60 ensures under the heel of the boot the transmission of the vertical forces between the boot and the ski. It seems that this construction improves the suspension effect by giving it more flexibility.

Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres modes de mise en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally, the present description is given for information only, and other modes of implementing the invention could be adopted without going beyond the scope of the latter.
