Description

L'invention concerne un dispositif interface entre un ski et des éléments de fixation avant et arrière qui sont destinés à retenir une chaussure en appui sur le ski.The invention relates to an interface device between a ski and front and rear binding elements which are intended to retain a boot bearing on the ski.

Une chaussure est retenue en appui sur le ski généralement par un élément de fixation avant et un élément arrière, qui retiennent chacun un embout de la semelle de chaussure. De façon usuelle, les éléments de fixation sont assemblés directement sur la surface supérieure du ski.A shoe is retained in abutment on the ski generally by a front binding element and a rear element, which each retain an end piece of the shoe sole. Usually, the binding elements are assembled directly on the upper surface of the ski.

On sait par ailleurs que la chaussure et les éléments de fixation exercent une influence sur la flexibilité de la poutre du ski, et sur son comportement sur la neige. Le comportement du ski sur la neige est en outre différent selon le type de ski pratiqué, slalom, descente, slalom géant, etc..., et selon le gabarit du skieur.It is also known that the boot and the binding elements exert an influence on the flexibility of the ski beam, and on its behavior on snow. The behavior of skiing on snow is also different depending on the type of skiing, slalom, downhill, giant slalom, etc., and depending on the skier's size.

On a recherché différents types d'interface qui sont placés entre les éléments de fixation et le ski, de façon à modifier l'influence qu'exercent les éléments de fixation et la chaussure sur la poutre qui constitue le ski.We have sought different types of interface which are placed between the binding elements and the ski, so as to modify the influence exerted by the binding elements and the boot on the beam which constitutes the ski.

Par exemple, on connait d'après la demande de brevet WO 82/03182 un dispositif interface qui tend à réduire l'influence des éléments de fixation et de la chaussure, de façon que le ski présente en flexion une courbe régulière, aussi proche que possible de sa courbure à l'état nu.For example, according to patent application WO 82/03182, an interface device is known which tends to reduce the influence of the binding elements and of the boot, so that the ski has a regular curve in flexion, as close as possible of its curvature in the naked state.

On connait également d'autres dispositifs interface qui jouent un rôle d'amortissement sur le ski. Un tel dispositif est connu d'après la demande de brevet n° WO 83/03360. Ce dispositif comprend une plaque sur laquelle sont montés les éléments de fixation. Sous la plaque se trouve un matériau élastiquement compressible. Une extrémité de la plaque est assemblée de façon solidaire au ski, et l'autre extrémité peut coulisser librement contre la force de rappel élastique de petits blocs de matériau compressible.Other interface devices are also known which play a damping role on the ski. Such a device is known from patent application No. WO 83/03360. This device comprises a plate on which the fixing elements are mounted. Under the plate is an elastically compressible material. One end of the plate is assembled integrally with the ski, and the other end can slide freely against the elastic return force of small blocks of compressible material.

Un tel dispositif donne de bon résultats, mais la transmission des sollicitations et des efforts entre la chaussure et le ski n'est pas optimale. En effet, les sollicitations et les efforts verticaux transitent en grande partie par les extrémités de la plaque qui sont déportées par rapport aux extrémités de la chaussure.Such a device gives good results, but the transmission of the stresses and forces between the boot and the ski is not optimal. Indeed, the stresses and the vertical forces pass largely through the ends of the plate which are offset relative to the ends of the shoe.

Un autre dispositif interface est connu d'après la demande de brevet EP 409 749. Dans ce dispositif, la plaque peut osciller de façon élastique selon une direction longitudinale par rapport au ski. Ce dispositif présente un inconvénient semblable au dispositif précédent. Les efforts et sollicitations ne sont pas transmis de façon précise entre la chaussure et le ski.Another interface device is known from patent application EP 409 749. In this device, the plate can oscillate resiliently in a longitudinal direction relative to the ski. This device has a drawback similar to the previous device. The forces and stresses are not transmitted in a precise manner between the boot and the ski.

Un des buts de l'invention est de proposer un dispositif interface entre un ski et des éléments de fixation, qui assure une bonne transmission des efforts de pilotage du ski entre la chaussure et le ski.One of the aims of the invention is to propose an interface device between a ski and binding elements, which ensures good transmission of the driving forces of the ski between the boot and the ski.

Un autre but de la présente invention est de proposer un dispositif interface qui assure un amortissement efficace des flexions du ski dans un plan vertical et longitudinal, et une transmission précise des efforts de pilotage de la chaussure sur le ski lors des déclenchements de virage et en phase de conduite de ski.Another object of the present invention is to provide an interface device which ensures effective damping of the flexions of the ski in a vertical and longitudinal plane, and a precise transmission of the driving forces of the boot on the ski during the initiations of the turn and in ski driving phase.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, cette description étant toutefois donnée à titre indicatif, et non limitatif.Other objects and advantages of the present invention will appear during the description which follows, this description being however given by way of indication, and not limitation.

Le dispositif interface selon l'invention est situé entre un ski et des éléments de fixation avant et arrière qui sont destinés à retenir les extrémités d'une chaussure, les éléments de fixation étant situés dans une zone centrale du ski qui est appelée le patin, et comprenant chacun une embase par laquelle ils sont reliés au ski.The interface device according to the invention is located between a ski and front and rear binding elements which are intended to retain the ends of a boot, the binding elements being located in a central zone of the ski which is called the skate, and each comprising a base by which they are connected to the ski.

Le dispositif selon l'invention comprend une plaque longiligne dont chaque extrémité est reliée au ski en avant et en arrière des éléments de fixation ;The device according to the invention comprises a slender plate, each end of which is connected to the ski in front and behind the binding elements;

Une extrémité de la plaque est surélevée par rapport à la surface du ski et assemblée au ski par une liaison élastiquement déformable selon une direction longitudinale ;One end of the plate is raised relative to the surface of the ski and assembled to the ski by an elastically deformable connection in a longitudinal direction;

la plaque présente vers l'une de ses extrémités une zone de montage pour recevoir de façon solidaire un élément de fixation, qui est dit premier élément.the plate has, towards one of its ends, a mounting zone for integrally receiving a fixing element, which is said to be the first element.

Le dispositif est caractérisé par le fait qu'il comprend dans la zone de l'autre élément de fixation qui est dit second élément, une cale rigide qui est située sous la plaque en appui vers le bas contre la surface supérieure du ski, et sur lequel la plaque est maintenue en appui vers le bas, la cale rigide assurant une transmission directe des sollicitations verticales entre la plaque dans la zone du second élément et le ski.The device is characterized by the fact that it comprises in the region of the other binding element which is said to be the second element, a rigid wedge which is located under the plate bearing downwards against the upper surface of the ski, and on which the plate is held in downward support, the rigid block ensuring a direct transmission of the vertical stresses between the plate in the zone of the second element and the ski.

L'invention sera mieux comprise en se référant à la description ci-dessous, ainsi qu'aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below, as well as to the accompanying drawings which form an integral part thereof.

La figure 1 représente de façon schématique, en vue de côté, et en coupe, un ski équipé d'éléments de fixation et du dispositif interface selon une premier mode de mise en oeuvre de l'invention.Figure 1 shows schematically, in side view, and in section, a ski equipped with fastening elements and the interface device according to a first embodiment of the invention.

La figure 2 représente en perspective le dispositif interface de la figure 1.FIG. 2 shows in perspective the interface device of FIG. 1.

La figure 3 est une vue semblable à la figure 1 et correspond à un autre mode de mise en oeuvre de l'invention.Figure 3 is a view similar to Figure 1 and corresponds to another embodiment of the invention.

La figure 4 est une vue en perspective du dispositif interface de la figure 3.FIG. 4 is a perspective view of the interface device of FIG. 3.

La figure 5 est relative à une autre variante de mise en oeuvre de l'invention.FIG. 5 relates to another variant implementation of the invention.

La figure 1 représente la partie médiane d'un ski 1, que l'on appelle usuellement le patin. Dans cette zone, une chaussure 2 est retenue en appui sur le ski 1 par un élément de fixation avant 3 et un élément de fixation arrière 4.Figure 1 shows the middle part of a ski 1, which is usually called the skate. In this zone, a boot 2 is retained in abutment on the ski 1 by a front binding element 3 and a rear binding element 4.

De façon connue, l'élément de fixation avant 3 présente une mâchoire 5 de retenue de l'extrémité avant de la chaussure. La mâchoire 5 est portée par un corps 7, qui est relié au ski par l'intermédiaire d'une embase 8. Ainsi que cela est visible dans la figure 1, l'embase 8 se prolonge vers l'arrière par une plaque d'appui 9 sur laquelle repose la semelle de chaussure dans sa zone avant.In known manner, the front fastening element 3 has a jaw 5 for retaining the front end of the shoe. The jaw 5 is carried by a body 7, which is connected to the ski via a base 8. As can be seen in FIG. 1, the base 8 is extended towards the rear by a plate of support 9 on which the shoe sole rests in its front zone.

De façon analogue, l'élément de fixation arrière 4 présente une mâchoire 10 de retenue de l'extrémité arrière de la chaussure, qui est portée par un corps 11. Le corps 11 est lui-même relié au ski par l'intermédiaire d'un embase 12. L'embase 12 présente dans sa partie avant une plaque d'appui 13 sur laquelle repose l'extrémité arrière de la semelle de chaussure. De façon connue, le corps est monté coulissant le long de l'embase, et un ressort s'oppose à son mouvement vers l'arrière de façon élastique.Similarly, the rear binding element 4 has a jaw 10 for retaining the rear end of the boot, which is carried by a body 11. The body 11 is itself connected to the ski by means of a base 12. The base 12 has in its front part a support plate 13 on which the rear end of the shoe sole rests. In known manner, the body is slidably mounted along the base, and a spring resists its movement backwards in an elastic manner.

Les éléments de fixation 3 et 4 sont reliés au ski 1 par l'intermédiaire d'un dispositif interface 14 qui va maintenant être décrit plus en détail.The fastening elements 3 and 4 are connected to the ski 1 via an interface device 14 which will now be described in more detail.

Le dispositif interface comprend une plaque longiligne 15, qui s'étend entre les éléments de fixation 3 et 4 et la surface supérieure du ski. La plaque 15 est rigide, elle est réalisée en tout matériau approprié, notamment en alliage d'aluminium ou en matériau composite.The interface device comprises a slender plate 15, which extends between the fastening elements 3 and 4 and the upper surface of the ski. The plate 15 is rigid, it is made of any suitable material, in particular aluminum alloy or composite material.

Dans l'exemple illustré, la plaque 15 est surélevée par rapport à la surface supérieure du ski sur la plus grande partie de sa longueur. La plaque 15 présente dans sa partie avant une zone de montage 15a où est assemblé l'élément de fixation avant 3, par l'intermédiaire de son embase 8. Dans sa partie arrière, la plaque 15 présente une zone de montage 15b pour l'embase 12 de l'élément de fixation arrière 4. Les deux éléments de fixation avant et arrière 3 et 4 sont donc assemblés à la plaque 15.In the example illustrated, the plate 15 is raised relative to the upper surface of the ski over most of its length. The plate 15 has in its front part a mounting zone 15a where the front fixing element 3 is assembled, by means of its base 8. In its rear part, the plate 15 has a mounting zone 15b for the base 12 of the rear fixing element 4. The two front and rear fixing elements 3 and 4 are therefore assembled to the plate 15.

La plaque 15 est reliée au ski dans sa partie avant et dans sa partie arrière. Dans sa partie arrière, la plaque 15 présente une extrémité abaissée 16, qui vient effleurer la surface supérieure du ski. L'extrémité 16 est assemblée de façon solidaire au ski par tout moyen approprié, par exemple par des vis schématisées en 17. Naturellement, ceci n'est pas limitatif et tout autre mode de solidarisation convient. Par exemple, la partie arrière de la plaque pourrait présenter un sabot ou une cale d'épaisseur qui la maintient surélevée par rapport au ski. La solidarisation se fait par exemple par des vis qui traversent la plaque et la cale ou le sabot.The plate 15 is connected to the ski in its front part and in its rear part. In its rear part, the plate 15 has a lowered end 16 which touches the upper surface of the ski. The end 16 is assembled integrally with the ski by any suitable means, for example by screws shown diagrammatically at 17. Naturally, this is not limiting and any other method of securing is suitable. For example, the rear part of the plate could have a shoe or a shim which keeps it raised relative to the ski. The connection is made for example by screws which pass through the plate and the wedge or the shoe.

L'extrémité avant de la plaque est reliée au ski par un moyen d'amortissement qui est actif selon une direction longitudinale. Dans l'exemple illustré, l'extrémité avant 19 de la plaque 15 s'étend en avant au delà de l'embase 8. Elle est surélevée par rapport au ski. Elle surplombe un support 20 qui est relié de façon solidaire au ski, par tout moyen approprié, par exemple par des vis. En outre, une couche de colle 21 assemble la plaque au support 20. Cette couche de colle présente à la fois des propriétés adhésives, et à la fois des qualités d'amortissement au cisaillement. Elle autorise donc, tout en offrant une résistance, un mouvement relatif de l'extrémité avant 19 de la plaque par rapport au support 20, au moins selon une direction horizontale et longitudinale. Etant donnée la position de la plaque 15 par rapport à la surface supérieure du ski, on comprend qu'un tel mouvement relatif de l'extrémité 19 par rapport au support 20 se produit lors des mouvements de flexion et de contreflexion du ski. De préférence, la couche de colle 21 offre une résistance dynamique aux mouvements longitudinaux de la plaque 20.The front end of the plate is connected to the ski by a damping means which is active in a longitudinal direction. In the example illustrated, the front end 19 of the plate 15 extends forwardly beyond the base 8. It is raised relative to the ski. It overlooks a support 20 which is integrally connected to the ski, by any appropriate means, for example by screws. In addition, a layer of glue 21 assembles the plate to the support 20. This layer of glue has both adhesive properties and both shear damping qualities. It therefore allows, while offering resistance, a relative movement of the front end 19 of the plate relative to the support 20, at least in a horizontal and longitudinal direction. Given the position of the plate 15 relative to the upper surface of the ski, it is understood that such a relative movement of the end 19 relative to the support 20 occurs during the flexion and counter-bending movements of the ski. Preferably, the adhesive layer 21 offers dynamic resistance to the longitudinal movements of the plate 20.

Selon un mode de réalisation préférentiel, une couche de matériau élastiquement compressible 25 s'étend entre la plaque et le ski, dans la zone de montage 15b de l'élément de fixation arrière 4. De préférence, la couche 25 s'étend également vers l'avant en direction de l'élément de fixation avant 3. Il est avantageux que la couche 25 présente des qualités d'amortissement dynamique selon une direction verticale.According to a preferred embodiment, a layer of elastically compressible material 25 extends between the plate and the ski, in the mounting zone 15b of the rear binding element 4. Preferably, the layer 25 also extends towards the front towards the front fixing element 3. It is advantageous for the layer 25 to have dynamic damping qualities in a vertical direction.

Une cale rigide 26 est par ailleurs interposée entre la plaque 15, au niveau de la zone de montage avant 15a, et la surface supérieure du ski. De préférence, la cale 26 s'étend sous l'embase 8 de l'élément de fixation avant 3, et sous la plaque d'appui 9 sur laquelle repose l'avant de la chaussure. La cale 26 est reliée de façon solidaire à la surface supérieure du ski. Elle présente une largeur sensiblement égale à la largeur du ski dans cette zone. La plaque 15 est en appui direct sur la cale 26, et la cale est en appui direct contre la surface supérieure du ski.A rigid wedge 26 is also interposed between the plate 15, at the front mounting zone 15a, and the upper surface of the ski. Preferably, the wedge 26 extends under the base 8 of the front fastening element 3, and under the support plate 9 on which the front of the shoe rests. The wedge 26 is integrally connected to the upper surface of the ski. It has a width substantially equal to the width of the ski in this zone. The plate 15 is in direct contact with the wedge 26, and the wedge is in direct contact with the upper surface of the ski.

Avantageusement, le support 20 et la cale 26 ne constituent qu'une seule et même pièce, c'est-à-dire que la cale 26 est le prolongement vers l'arrière du support 20. Toutefois, ce n'est pas limitatif, et l'efficacité du dispositif est à priori plus grande si ces éléments sont disjoints.Advantageously, the support 20 and the shim 26 constitute only one and the same part, that is to say that the shim 26 is the extension towards the rear of the support 20. However, this is not limiting, and the efficiency of the device is a priori greater if these elements are separated.

Ainsi, l'avant de la chaussure se trouve en liaison directe avec le ski, étant donné que la plaque 15, sous l'élément de fixation avant 3, se trouve en appui contre la cale 26. La cale 26 assure une transmission précise des efforts de pilotage que l'avant de la chaussure imprime au ski, notamment dans les phases de déclenchement de virages. De plus, l'interface réalise un amortissement efficace du ski dans un plan longitudinal et vertical.Thus, the front of the boot is in direct connection with the ski, since the plate 15, under the front fastening element 3, is in abutment against the wedge 26. The wedge 26 ensures precise transmission of the piloting efforts that the front of the boot imprints on the ski, especially in the initiation phases of turns. In addition, the interface provides effective damping of the ski in a longitudinal and vertical plane.

Selon un mode préférentiel de réalisation, la plaque 15 présente par ailleurs plusieurs orifices oblongs 30, qui sont répartis sur sa surface. Des rondelles épaulées 31 traversent chacun de ces orifices, et sont solidarisées au ski au moyen de vis 32. Les rondelles épaulées 31 autorisent un mouvement de la plaque 15 selon une direction longitudinale, mais entravent un mouvement de celle-ci selon une direction latérale, ou une direction verticale vers le haut au delà d'un jeu de fonctionnement. Les rondelles 31 maintiennent notamment la plaque 15 en appui contre la cale 26. Dans la figure 2 sont également visibles des orifices 33 situés à l'extrémité avant 19 de la plaque. Ces orifices permettent d'accéder aux vis d'assemblage du support 20 au ski.According to a preferred embodiment, the plate 15 also has several oblong orifices 30, which are distributed over its surface. Shouldered washers 31 pass through each of these orifices, and are secured to the ski by means of screws 32. The shouldered washers 31 allow movement of the plate 15 in a longitudinal direction, but hinder a movement of the latter in a lateral direction, or a vertical direction upwards beyond a working clearance. The washers 31 in particular hold the plate 15 in abutment against the wedge 26. In FIG. 2 are also visible orifices 33 situated at the front end 19 of the plate. These holes provide access to the assembly screws of the support 20 to the ski.

On a obtenu de bons résultats avec une plaque 15 surélevée de 5 millimètres environ par rapport au ski, et une couche de colle 21 de 2 millimètres environ d'épaisseur. Ceci naturellement n'est pas limitatif.Good results have been obtained with a plate 15 raised by about 5 millimeters relative to the ski, and a layer of glue 21 of about 2 millimeters thick. This of course is not limiting.

La figure 3 représente un autre mode de mise en oeuvre de l'invention. Selon cette variante, l'interface présente une plaque 35, dont l'extrémité fixe se trouve vers l'avant du ski, et l'extrémité mobile vers l'arrière. La plaque 35 présente une zone de montage 35a pour l'élément de fixation avant 3, et une zone de montage 35b pour l'élément de fixation arrière 4. Dans le mode de réalisation illustré, la plaque 35 se trouve surélevée par rapport à la surface supérieure du ski sur toute sa longueur. L'extrémité avant 37 de la plaque est pincée entre l'embase 8 de l'élément de fixation avant 3, et une cale 36 solidaire du ski à laquelle l'embase 8 est assemblée. La cale 36 s'étend sur toute la longueur de l'embase 8, y compris, de préférence la plaque d'appui 9, et sur toute la largeur du ski. Ainsi, l'ensemble constitué par l'embase 8, l'extrémité avant de la plaque 35, et la cale 36, se trouve assemblé de façon solidaire au ski. Chaque élément peut être assemblé de façon solidaire à l'élément inférieur, ou bien, tel que cela est visible dans la figure 3, les vis d'assemblage de l'embase 8 sont vissées dans le ski, et traversent la plaque et la cale. Quoiqu'il en soit, la plaque 35 est maintenue en appui contre la cale 36.FIG. 3 represents another embodiment of the invention. According to this variant, the interface has a plate 35, the fixed end of which is towards the front of the ski, and the mobile end towards the rear. The plate 35 has a mounting zone 35a for the front fixing element 3, and a mounting zone 35b for the rear fixing element 4. In the illustrated embodiment, the plate 35 is raised relative to the upper surface of the ski over its entire length. The front end 37 of the plate is pinched between the base 8 of the front fixing element 3, and a wedge 36 integral with the ski to which the base 8 is assembled. The wedge 36 extends over the entire length of the base 8, including, preferably, the support plate 9, and over the entire width of the ski. Thus, the assembly constituted by the base 8, the front end of the plate 35, and the wedge 36, is assembled in solidarity with the ski. Each element can be assembled integrally with the lower element, or else, as can be seen in FIG. 3, the assembly screws of the base 8 are screwed into the ski, and pass through the plate and the wedge. . Anyway, the plate 35 is held in abutment against the wedge 36.

Dans sa partie arrière, la plaque 35 est reliée au ski par un moyen amortisseur qui est actif selon une direction longitudinale. Dans l'exemple illustré, la plaque 35 s'étend au-delà de l'élément de fixation arrière 4. L'extrémité arrière 38 surplombe un support 39, qui est solidarisé au ski par tout moyen approprié, par exemple par des vis. Une couche de colle 40 relie par ailleurs l'extrémité 38 au support 30. Comme dans le cas précédent, cette couche de colle présente des qualités adhésives, et possède des qualités d'étirement selon une direction longitudinale. Elle offre une résistance à cet étirement. La colle, de préférence, présente des propriétés viscoélastiques.In its rear part, the plate 35 is connected to the ski by a damping means which is active in a longitudinal direction. In the example illustrated, the plate 35 extends beyond the rear fixing element 4. The rear end 38 overhangs a support 39, which is secured to the ski by any suitable means, for example by screws. A layer of adhesive 40 also connects the end 38 to the support 30. As in the previous case, this layer of adhesive has adhesive qualities, and has qualities of stretching in a longitudinal direction. It offers resistance to this stretch. The adhesive, preferably, has viscoelastic properties.

Le support 39 et la couche de colle 40 maintiennent l'extrémité arrière 38 de la plaque 35 sensiblement à la même hauteur que son extrémité avant.The support 39 and the adhesive layer 40 maintain the rear end 38 of the plate 35 at substantially the same height as its front end.

Dans le cas présent, lors de flexion ou de contreflexion du ski, c'est l'extrémité arrière 38 de la plaque 35 qui se déplace selon une direction longitudinale, par rapport au ski, et la couche de colle 40, en s'étirant, offre une résistance à ce mouvement relatif. De préférence, le matériau de la couche 40 est choisi pour que la couche offre une résistance de type dynamique.In the present case, when the ski is bent or deflected, it is the rear end 38 of the plate 35 which moves in a longitudinal direction, relative to the ski, and the adhesive layer 40, stretching , offers resistance to this relative movement. Preferably, the material of the layer 40 is chosen so that the layer offers a dynamic type resistance.

De préférence, comme dans le cas précédent, la plaque 35 présente un ou plusieurs orifices oblongs 42 dans lesquels sont engagés des rondelles épaulées 43 solidarisées au ski par des vis 44. Ce montage est du même type que le montage précédent avec les orifices 30, les rondelles 31 et les vis 32. Les rondelles maintiennent notamment la partie arrière de la plaque 35 en appui contre les supports 39 et la couche de colle 40.Preferably, as in the previous case, the plate 35 has one or more oblong holes 42 in which are engaged shoulder washers 43 secured to the ski by screws 44. This assembly is of the same type as the previous assembly with the holes 30, the washers 31 and the screws 32. The washers in particular hold the rear part of the plate 35 in abutment against the supports 39 and the layer of adhesive 40.

De plus, une couche de matériau compressible 46 est, de préférence, intercalée entre la plaque 35 et la surface supérieure du ski, sous l'élément de fixation arrière 4 au moins. De préférence, le matériau de la couche 46 a des propriétés viscoélastiques et la couche 46 est amortissante selon une direction verticale.In addition, a layer of compressible material 46 is preferably interposed between the plate 35 and the upper surface of the ski, under the rear fastening element 4 at least. Preferably, the material of the layer 46 has viscoelastic properties and the layer 46 is damping in a vertical direction.

Lors de la pratique du ski, et en particulier lors des flexions du ski, la plaque 35 exerce une influence sur la courbure du ski, et sa répartition de pression sur la neige. D'un autre côté, comme dans le cas précédent, l'extrémité avant de la chaussure se trouve en contact direct avec la surface supérieure du ski, étant donné que la plaque d'appui 9 repose directement sur le ski par l'intermédiaire de la plaque 35, et de la cale 36. Ainsi, le ski présente une bonne précision de conduite et une grande facilité de déclenchement.When skiing, and in particular when flexing the ski, the plate 35 exerts an influence on the curvature of the ski, and its distribution of pressure on the snow. On the other hand, as in the previous case, the front end of the boot is in direct contact with the upper surface of the ski, since the support plate 9 rests directly on the ski by means of the plate 35, and the wedge 36. Thus, the ski has good driving precision and great ease of triggering.

La figure 5 illustre une autre variante de réalisation, selon laquelle l'interface présente une plaque 55, qui s'étend contre la surface supérieure du ski, sur la plus grande partie de sa longueur. La plaque 55 présente une zone de montage 55a pour l'élément de fixation avant 3, et une zone de montage 55b pour l'élément de fixation arrière 4. Ainsi, dans la figure 5, il est visible que l'extrémité arrière 56 de la plaque 55 est solidarisée au ski par pincement entre l'embase 12 de l'élément de fixation arrière 4 et la surface supérieure du ski. Eventuellement, une couche mince de matériau élastiquement compressible peut être intercalé à ce niveau entre la plaque 55 et la surface supérieure du ski, ou bien entre la plaque 55 et l'embase 12. Cette couche n'est pas représentée en figure 5.FIG. 5 illustrates another alternative embodiment, according to which the interface has a plate 55, which extends against the upper surface of the ski, over most of its length. The plate 55 has a mounting zone 55a for the front fixing element 3, and a mounting zone 55b for the rear fixing element 4. Thus, in FIG. 5, it is visible that the rear end 56 of the plate 55 is secured to the ski by pinching between the base 12 of the rear binding element 4 and the upper surface of the ski. Optionally, a thin layer of elastically compressible material can be inserted at this level between the plate 55 and the upper surface of the ski, or else between the plate 55 and the base 12. This layer is not shown in FIG. 5.

Vers l'avant, l'embase 8 de l'élément de fixation avant 3 est assemblé de façon solidaire à la plaque 55.Towards the front, the base 8 of the front fixing element 3 is assembled integrally with the plate 55.

En avant de l'élément de fixation avant 3, la plaque 55 présente une extrémité 57, qui est surélevée par rapport à la surface supérieure du ski. L'extrémité 57 surplombe un support 58, et une couche de colle 59 du même genre que les couches précédentes relie l'extrémité 57 au support 58.In front of the front fixing element 3, the plate 55 has an end 57, which is raised relative to the upper surface of the ski. The end 57 overhangs a support 58, and a layer of glue 59 of the same kind as the previous layers connects the end 57 to the support 58.

Comme dans les cas précédents, de préférence, la plaque 45 présente des orifices oblongs 60 qui sont traversés par des rondelles épaulées 61, lesquelles rondelles sont solidarisées au ski par des vis 62. Les rondelles 61 autorisent un mouvement de coulissement de la plaque par rapport au ski selon une direction longitudinale, mais la retiennent verticalement vers le haut, et latéralement au jeu de fonctionnement près. Les rondelles 61 maintiennent notamment la plaque 45 en appui contre le ski au niveau de l'embase 8 de la fixation avant.As in the previous cases, preferably, the plate 45 has oblong orifices 60 which are crossed by shouldered washers 61, which washers are secured to the ski by screws 62. The washers 61 allow the plate to slide in relation to movement skiing in a longitudinal direction, but hold it vertically upwards, and laterally when playing close operation. The washers 61 in particular hold the plate 45 in abutment against the ski at the level of the base 8 of the front binding.

On comprend d'après ce qui précède que la plaque 55 influence la courbure du ski et sa répartition de pression sur la neige lors des phases de flexion. D'un autre côté, le ski présente une bonne précision de conduite et une grande facilité de déclenchement, étant donné que l'avant de la chaussure est en appui direct contre la surface supérieure du ski, car dans le cas présent, la plaque 55 se trouve elle-même en appui contre le ski.It will be understood from the above that the plate 55 influences the curvature of the ski and its pressure distribution over the snow during the bending phases. On the other hand, the ski has good driving precision and great ease of release, given that the front of the boot is in direct contact with the upper surface of the ski, because in this case, the plate 55 is itself in support against the ski.

L'amplitude du mouvement relatif de la plaque dépend de la hauteur de l'extrémité avant et l'extrémité arrière de la plaque par rapport au ski. Ici, l'extrémité arrière est proche de la fibre neutre du ski. Il est préférable que le support 58 soit plus épais que les supports 26 et 36 précédents, pour une efficacité de même ordre.The amplitude of the relative movement of the plate depends on the height of the front end and the rear end of the plate relative to the ski. Here, the rear end is close to the neutral fiber of the ski. It is preferable that the support 58 is thicker than the previous supports 26 and 36, for efficiency of the same order.

Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises 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 implementations of the invention could be adopted without departing from the scope thereof.

En particulier, il va de soi qu'il serait possible de permuter le rôle des éléments de fixation avant et arrière, en ce qui concerne leurs appuis directs sur le ski. En d'autres termes, il serait possible de mettre non pas l'élément de fixation avant, mais l'élément de fixation arrière en appui direct contre la surface supérieure du ski selon une direction verticale, notamment en plaçant sous l'élément de fixation arrière la cale rigide.In particular, it goes without saying that it would be possible to swap the role of the front and rear binding elements, as regards their direct support on the ski. In other words, it would be possible not to put the front binding element, but the rear binding element in direct support against the upper surface of the ski in a vertical direction, in particular by placing under the binding element rear rigid block.
