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.

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 un élément de fixation avant et un élément de fixation arrière. Les chaussures et les éléments de fixation se trouvent dans la zone centrale du ski qui est appelée couramment le patin.The skis which are used for alpine skiing consist of relatively long boards, on which the skier's shoes are retained by a front binding element and a rear binding element. The boots and the fasteners are located in the central area of the ski which is commonly called the skate.

Lorsque les éléments de fixation sont assemblés directement sur le ski, il est connu que la semelle de chaussure exerce sur le ski une action de raidissement dans la zone du patin. De plus, les éléments de fixation exercent sur la semelle de chaussure une action de pincement, dont la réaction est transmise au ski.When the binding elements are assembled directly on the ski, it is known that the shoe sole exerts on the ski a stiffening action in the area of the skate. In addition, the binding elements exert a gripping action on the sole of the boot, the reaction of which is transmitted to the ski.

De tels skis sont donc influencés dans leur flexion par la chaussure et les éléments de fixation.Such skis are therefore influenced in their bending by the boot and the binding elements.

Certains ensembles d'éléments de fixation ont été conçu pour atténuer au maximum les perturbations que la chaussure provoque dans la flexion du ski. Un tel ensemble de fixation est par exemple connu d'après la demande de brevet allemand DE-OS 3 109 754.Certain sets of binding elements have been designed to minimize the disturbances that the boot causes in the flexing of the ski. Such a fixing assembly is for example known from German patent application DE-OS 3 109 754.

Il existe d'autres dispositifs qui, au contraire, s'opposent à la flexion du ski ou bien par une action de raidissement, ou bien par une action d'amortissement dans la zone du patin, ou bien par une action combinée de raidissement et d'amortissement. Un tel dispositif est par exemple décrit dans la demande de brevet européen EP 104 185. Ce dispositif comprend une plaque qui supporte les éléments de fixation avant et arrière, dont la partie centrale est surélevée par rapport à la surface supérieure du ski, dont une extrémité est solidarisée au ski, et dont l'autre extrémité est reliée au ski avec une possibilité de mouvement relatif selon une direction longitudinale. Des blocs élastiquement déformables exercent une action d'amortissement sur ce mouvement longitudinal. En outre, ce dispositif comprend une couche de matériau élastiquement déformable qui est intercalée entre la partie centrale de la plaque et la surface supérieure du ski.There are other devices which, on the contrary, oppose the flexion of the ski either by a stiffening action, or by a damping action in the area of the skate, or by a combined stiffening action and depreciation. Such a device is for example described in European patent application EP 104 185. This device comprises a plate which supports the front and rear binding elements, the central part of which is raised relative to the upper surface of the ski, one end of which is secured to the ski, and the other end of which is connected to the ski with a possibility of relative movement in a longitudinal direction. Elastically deformable blocks exert a damping action on this longitudinal movement. In addition, this device comprises a layer of elastically deformable material which is interposed between the central part of the plate and the upper surface of the ski.

Un tel dispositif est efficace pour amortir les mouvements de flexion du ski. Par contre, ce dispositif n'a pas ou il a peu d'action sur les vibrations auxquelles le ski est soumis. Hors, de telles vibrations perturbent le contact entre la semelle du ski et la neige, et de ce fait, si ces vibrations ne sont pas amorties, la vitesse du ski et sa précision de conduite ne sont pas optimales.Such a device is effective in absorbing the flexing movements of the ski. On the other hand, this device has little or no action on the vibrations to which the ski is subjected. However, such vibrations disturb the contact between the sole of the ski and the snow, and therefore, if these vibrations are not damped, the speed of the ski and its driving precision are not optimal.

Un des buts de la présente invention est de proposer un dispositif interface qui assure un amortissement des flexions de ski, ainsi que des vibrations auxquelles il est soumis, en particulier celles qui sont susceptibles de provoquer un phénomène de résonance dans la partie avant du ski.One of the aims of the present invention is to propose an interface device which ensures damping of the ski flexes, as well as of the vibrations to which it is subjected, in particular those which are capable of causing a resonance phenomenon in the front part of the ski.

Un autre but de la présente invention est de proposer un dispositif interface qui soit simple, et facile à adapter sur un ski.Another object of the present invention is to provide an interface device which is simple and easy to adapt on a ski.

Un autre but de la présente invention est de proposer un dispositif interface qui assure une grande précision de la conduite du ski.Another object of the present invention is to provide an interface device which ensures high precision in the handling of the ski.

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 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 liés au ski dans la zone du patin, le dispositif comprend une plaque, avec une partie centrale longiligne s'étendant au-dessus de la surface supérieure du ski au-dessus de la zone du patin, une première extrémité de la plaque étant solidarisée au ski, et la seconde extrémité étant liée au ski pour un mouvement relatif par rapport au ski lors de ses mouvements de flexion, l'un au moins des éléments de fixation étant assemblé sur la plaque.The interface device 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 linked to the ski in the skate area, the device comprises a plate, with a elongated central part extending above the upper surface of the ski above the skate area, a first end of the plate being secured to the ski, and the second end being linked to the ski for a relative movement relative to the ski during its bending movements, at least one of the fastening elements being assembled on the plate.

Il est caractérisé par le fait que la seconde extrémité de la plaque est liée au ski par un bloc de matériau amortissant monté en sandwich entre la seconde extrémité de la plaque et la surface supérieure du ski.It is characterized by the fact that the second end of the plate is linked to the ski by a block of damping material sandwiched between the second end of the plate and the upper surface of the ski.

On a représenté schématiquement dans la figure 1 la zone centrale d'un ski 1, qui est couramment dénommée le patin. La figure montre également une chaussure 2, dont les extrémités avant et arrière sont respectivement retenues sur le ski par un élément de fixation avant 3 et un élément de fixation arrière 4.

De façon connue, l'élément de fixation avant 3 présente un organe de retenue 5 de l'extrémité avant de la chaussure, un corps 7, ainsi qu'une plaque d'appui 9 sur laquelle repose l'extrémité avant de la semelle de chaussure. Parallèlement, l'élément de fixation arrière 4 présente un organe de retenue 6, un corps 8, ainsi qu'une plaque d'appui 10 pour l'extrémité arrière de la semelle de chaussure.There is shown schematically in Figure 1 the central area of a ski 1, which is commonly referred to as the skate. The figure also shows a boot 2, the front and rear ends of which are respectively retained on the ski by a front binding element 3 and a rear binding element 4. The two front and rear binding elements 3 and 4 are of all types appropriate. In known manner, the front fastening element 3 has a retaining member 5 of the front end of the shoe, a body 7, as well as a support plate 9 on which the front end of the sole rests. shoe. In parallel, the rear fastening element 4 has a retaining member 6, a body 8, as well as a support plate 10 for the rear end of the shoe sole.

Les éléments de fixation avant et arrière 3 et 4 sont reliés au ski par l'intermédiaire d'un dispositif interface 12 qui va être maintenant décrit plus en détail.The front and rear binding elements 3 and 4 are connected to the ski by means of an interface device 12 which will now be described in more detail.

Le dispositif interface 12 présente principalement une plaque de liaison longiligne 13, qui s'étend au-dessus du ski, dans sa zone du patin. La plaque 13 est réalisée en tout matériau approprié, par exemple en alliage métallique. Elle pourrait être réalisée aussi en une matière synthétique ou un matériau composite.

Au moins l'un des éléments de fixation est assemblé à la partie centrale 14 de la plaque 13. Dans l'exemple illustré, c'est l'élément de fixation arrière 4 qui est assemblé au ski, par tout moyen approprié, et par exemple par des vis.The elongate connecting plate 13 has a central part 14, which is raised relative to the upper surface of the ski. At least one of the fastening elements is assembled to the central part 14 of the plate 13. In the example illustrated, it is the rear fixing element 4 which is assembled to the ski, by any suitable means, and for example by screws.

La plaque 13 présente par ailleurs une extrémité arrière 15, située en arrière de l'élément de fixation arrière 4, qui est solidarisée au ski par tout moyen approprié, et par exemple par des vis.The plate 13 also has a rear end 15, located behind the rear fixing element 4, which is secured to the ski by any suitable means, and for example by screws.

La plaque de liaison 13 présente une extrémité avant 16, qui, dans l'exemple illustré, s'étend au-delà de l'élément de fixation avant 3. L'extrémité avant 16 de la plaque est surélevée par rapport à la surface supérieure du ski, et un bloc de matériau élastiquement déformable 17 relie à ce niveau la plaque 16 au ski. Le bloc de matériau 17 présente par exemple une forme parrallélépipédique, et ses faces supérieure et inférieure sont respectivement solidarisées à la plaque 16 et au ski, par tout moyen approprié, et par exemple par collage. Le matériau 17 est ainsi monté en sandwich entre la plaque 16 et le ski.The connecting plate 13 has a front end 16, which, in the example illustrated, extends beyond the front fixing element 3. The front end 16 of the plate is raised relative to the upper surface of the ski, and a block of elastically deformable material 17 connects at this level the plate 16 to the ski. The block of material 17 has for example a parallelepiped shape, and its upper and lower faces are respectively secured to the plate 16 and to the ski, by any suitable means, and for example by bonding. The material 17 is thus sandwiched between the plate 16 and the ski.

Le matériau qui constitue le bloc 17 est de toute nature appropriée, mais de préférence, on choisit un matériau qui est capable de travailler au cisaillement, au moins selon la direction longitudinale définie par le ski, ainsi qu'à l'amortissement selon une direction verticale. Le matériau amortissant 17 est en effet sollicité de deux façons différentes. Lors des flexions de ski, l'extrémité avant de la plaque 13 a tendance à avancer relativement au ski, étant donné que son extrémité arrière 15 est solidaire du ski. Ce mouvement relatif sollicite le bloc de matériau 17 au cisaillement, et les mouvements de flexion du ski se trouvent ainsi amortis. Le bloc est également sollicité par des mouvements de flexion de l'extrémité avant du ski, c'est-à-dire ceux qui se produisent en avant de l'élément de fixation avant 3. Le bloc 17 est alors sollicité à la compression selon une direction verticale.The material which constitutes the block 17 is of any suitable nature, but preferably, a material is chosen which is capable of working in shearing, at least in the longitudinal direction defined by the ski, as well as in damping in a direction vertical. The damping material 17 is in fact stressed in two different ways. During ski flexions, the front end of the plate 13 tends to advance relative to the ski, since its rear end 15 is integral with the ski. This relative movement urges the block of material 17 to shear, and the flexion movements of the ski are thus damped. The block is also stressed by bending movements of the front end of the ski, that is to say those which occur in front of the front binding element 3. The block 17 is then subjected to compression according to a vertical direction.

Il faut ajouter que lorsque le bloc 17 est sollicité par la plaque au cisaillement, par réaction, l'avant du ski est soumis à un moment qui tend à faire plonger la spatule vers la neige.It should be added that when the block 17 is stressed by the shear plate, by reaction, the front of the ski is subjected to a moment which tends to cause the tip to plunge towards the snow.

On a remarqué que la disposition du bloc 17 monté en sandwich entre l'extrémité avant de la plaque 16 et le ski est efficace pour amortir ce que l'on a usage de dénommer le premier mode de flexion du ski, ou encore la première de flexion du ski, c'est-à-dire les vibrations de la partie avant du ski pour lesquelles l'élément de fixation avant constitue un noeud, et la spatule du ski constitue un ventre.It has been noted that the arrangement of the block 17 sandwiched between the front end of the plate 16 and the ski is effective in absorbing what is used to denote the first mode of flexion of the ski, or even the first of bending of the ski, that is to say the vibrations of the front part of the ski for which the front binding element constitutes a knot, and the ski tip constitutes a belly.

On a obtenu de bons résultats avec un bloc 17 dont la longueur était comprise entre 50 et 300 millimètres, et de préférence voisine de 150 millimètres. L'épaisseur du bloc est de préférence supérieure à 5 millimètres.Good results have been obtained with a block 17 whose length was between 50 and 300 millimeters, and preferably close to 150 millimeters. The thickness of the block is preferably greater than 5 millimeters.

Le matériau utilisé est par exemple du caoutchouc ou un élastomère de polyuréthane. On a obtenu de bons résultats avec un matériau du commerce connu sous la dénomination commerciale "SORBOTANE".The material used is for example rubber or a polyurethane elastomer. Good results have been obtained with a commercial material known under the trade name "SORBOTANE".

Toutefois, ces valeurs et ces indications n'ont pas de valeur limitative pour l'invention.However, these values and these indications have no limiting value for the invention.

On peut aussi remplacer le bloc 17 par un support rigide surmonté d'une couche de colle qui présente la propriété de travailler au cisaillement, c'est-à-dire une colle qui s'étire sous l'effet d'une sollicitation en cisaillement en opposant une résistance à cette déformation. Cette couche aurait une épaisseur de l'ordre de 2 millimètres.It is also possible to replace the block 17 with a rigid support surmounted by a layer of adhesive which has the property of working in shear, that is to say an adhesive which stretches under the effect of a shear stress. by offering resistance to this deformation. This layer would have a thickness of the order of 2 millimeters.

Dans les modes de réalisation illustrés dans les figures, l'élément de fixation avant 3 est assemblé non pas à la plaque 13, mais au ski 1 par l'intermédiaire d'une cale 20. La cale 20 surélève l'élément de fixation avant 3 et assure une transmission directe des sollicitations et des efforts entre le ski et la chaussure à ce niveau.In the embodiments illustrated in the figures, the front fixing element 3 is assembled not to the plate 13, but to the ski 1 by means of a wedge 20. The wedge 20 raises the front fixing element 3 and ensures direct transmission of the stresses and forces between the ski and the boot at this level.

En se référant à la figure 1, la cale 20 s'étend sous l'embase 21 de l'élément de fixation, et elle est solidarisée au ski par tout moyen approprié, et par exemple par des vis 22. La cale 20 présente, dans sa partie supérieure, des pots 23, 24 qui traversent l'épaisseur de la plaque 13, et sur lesquels l'embase 21 de l'élément de fixation vient reposer. L'épaisseur de la cale 20 est égale ou légèrement inférieure à la hauteur à laquelle la plaque est surélevée par rapport au ski dans cette zone.Referring to FIG. 1, the wedge 20 extends under the base 21 of the binding element, and it is secured to the ski by any suitable means, and for example by screws 22. The wedge 20 has, in its upper part, pots 23, 24 which pass through the thickness of the plate 13, and on which the base 21 of the fixing element comes to rest. The thickness of the wedge 20 is equal to or slightly less than the height at which the plate is raised relative to the ski in this zone.

Les plots 23 et 24 présentent une hauteur qui est supérieure à l'épaisseur de la plaque, et la plaque présente au niveau des plots des ouvertures, de telle façon que la partie avant de la plaque puisse coulisser librement par rapport à la cale, lors des mouvements de flexion du ski.The studs 23 and 24 have a height which is greater than the thickness of the plate, and the plate has at the level of the studs of the openings, so that the front part of the plate can slide freely relative to the wedge, during bending movements of the ski.

L'embase 21 de l'élément de fixation avant 3 repose sur les pots 23, 24, et, dans le mode de réalisation illustré, elle est assemblée à ces pots au moyen de vis.The base 21 of the front fixing element 3 rests on the pots 23, 24, and, in the illustrated embodiment, it is assembled to these pots by means of screws.

La figure 2 représente un premier mode de réalisation de ce montage, avec des pots 23a, et 24a en forme de cheminée, qui traversent des ouvertures 25a et 26a de la plaque 13 en forme de lumières orientée selon une direction longitudinale. Selon une direction longitudinale, les ouvertures 23a à 26a ont une longueur supérieure à celle des plots 23 à 26. Eventuellement, l'espace compris entre les plots et le contour des ouvertures est comblé par un matériau élastiquement déformable, par exemple un matériau amortisseur.FIG. 2 represents a first embodiment of this arrangement, with pots 23a, and 24a in the form of a chimney, which pass through openings 25a and 26a of the plate 13 in the form of lights oriented in a longitudinal direction. In a longitudinal direction, the openings 23a to 26a have a length greater than that of the studs 23 to 26. Optionally, the space between the studs and the outline of the openings is filled with an elastically deformable material, for example a damping material.

La figure 3 représente une variante de réalisation, selon laquelle la cale avant 20 présente des pots latéraux 23b, qui traversent la plaque au niveau d'ouverture latérale 25b en forme d'encoche.FIG. 3 represents an alternative embodiment, according to which the front wedge 20 has lateral pots 23b which pass through the plate at the lateral opening level 25b in the form of a notch.

De préférence, les plots s'étendent au moins dans les zones de l'embase 21 où se situent les vis d'assemblage de l'élément de fixation au ski, et de préférence, ils s'étendent également vers l'arrière de l'élément de fixation, de façon à supporter au moins en partie la plaque d'appui 9 de l'élément de fixation.Preferably, the studs extend at least in the areas of the base 21 where the assembly screws of the binding element are located, and preferably, they also extend towards the rear of the ski. 'fixing element, so as to support at least partially the support plate 9 of the fixing element.

De plus, de façon préférentielle, les plots de la cale 20 présentent une longueur suffisante pour que l'élément de fixation avant 3 puisse être assemblé dans une position ajustable en fonction de la longueur de la chaussure du skieur.In addition, preferably, the studs of the wedge 20 have a sufficient length so that the front fastening element 3 can be assembled in an adjustable position as a function of the length of the skier's shoe.

Selon une variante de réalisation, les pots constituent pour la plaque une butée vers l'avant de façon à protéger le bloc 17 dans le cas d'une flexion excessive du ski. Dans une telle circonstance, la plaque vient prendre appui directement sur les plots après une flexion déterminée du ski.According to an alternative embodiment, the pots constitute a stop for the plate towards the front so as to protect the block 17 in the event of excessive bending of the ski. In such a circumstance, the plate comes to bear directly on the studs after a determined bending of the ski.

Selon une autre variante de réalisation, les plots jouent un rôle de guidage dans le mouvement longitudinal de la plaque, c'est-à-dire que leur dimension transversale est ajustée par rapport aux dimensions transversales de la plaque et de ses ouvertures à ce niveau pour entraver tout mouvement transversal de la plaque. La figure 3 illustre un tel ajustement.According to another alternative embodiment, the studs play a guiding role in the longitudinal movement of the plate, that is to say that their transverse dimension is adjusted relative to the transverse dimensions of the plate and of its openings at this level. to hinder any transverse movement of the plate. Figure 3 illustrates such an adjustment.

Selon une autre variante de réalisation, des blocs de matériau amortisseur sont insérés entre les pots 23 et 24, et la plaque au niveau des ouvertures 25 et 26, pour réaliser un amortissement selon une direction longitudinale.According to another alternative embodiment, blocks of damping material are inserted between the pots 23 and 24, and the plate at the level of the openings 25 and 26, in order to produce damping in a longitudinal direction.

Dans les figures 1 à 3 on aura présenté un bloc de matériau élastiquement compressible 30, qui s'étend entre la zone arrière de la partie centrale 14 de la plaque et la surface supérieure du ski. De préférence, le bloc de matériau 30 présente des qualités d'amortissement et il s'étend au moins sous l'élément de fixation arrière 4. Ce bloc a pour fonction d'amortir les sollicitations verticales entre la chaussure et le ski à ce niveau, et notamment les sollicitations qui sont dues à une flexion de la plaque 13, ou à une flexion du ski 1 à ce niveau.In FIGS. 1 to 3, a block of elastically compressible material 30 will have been presented, which extends between the rear zone of the central part 14 of the plate and the upper surface of the ski. Preferably, the block of material 30 has damping qualities and it extends at least under the rear fastening element 4. This block has the function of damping the vertical stresses between the boot and the ski at this level , and in particular the stresses which are due to a bending of the plate 13, or to a bending of the ski 1 at this level.

La figure 4 représente une variante de réalisation de la partie avant du dispositif interface. Selon cette variante, la cale 20 se prolonge vers l'avant par une languette 31 qui s'étend sous l'extrémité avant 16 de la plaque. Le bloc de matériau amortissant 17 est alors monté en sandwich entre la plaque et la languette 31. Eventuellement, la solidarisation de la cale 20 au ski peut être renforcée au niveau de la languette 31 par des vis 32. Cette disposition permet d'éviter un collage du bloc amortissant 17 sur la surface supérieure du ski, qui est souvent une opération délicate. Egalement, il est possible grâce à cette disposition de démonter sans difficulté et sans détérioration le dispositif interface.FIG. 4 represents an alternative embodiment of the front part of the interface device. According to this variant, the wedge 20 is extended forward by a tongue 31 which extends under the front end 16 of the plate. The block of damping material 17 is then sandwiched between the plate and the tongue 31. Optionally, the attachment of the wedge 20 to the ski can be reinforced at the tongue 31 by screws 32. This arrangement makes it possible to avoid bonding of the damping block 17 on the upper surface of the ski, which is often a delicate operation. Also, it is possible thanks to this arrangement to dismantle the interface device without difficulty and without deterioration.

Les figures 5 et 6 illustrent des variantes de réalisation du dispositif au niveau de la fixation arrière.Figures 5 and 6 illustrate alternative embodiments of the device at the rear attachment.

La construction de la figure 5 est semblable à celle qui était décrite en référence à la figure 1, sauf que le bloc de matériau amortissant 30 situé sous l'élément de fixation arrière 4 est ici remplacé par un bloc rigide 43 qui est situé entre la plaque 13 et la surface supérieure du ski. Ce bloc 43 assure une liaison directe entre l'élément de fixation arrière 4 et la surface supérieure du ski.The construction of FIG. 5 is similar to that which was described with reference to FIG. 1, except that the block of damping material 30 located under the rear fastening element 4 is here replaced by a rigid block 43 which is located between the plate 13 and the upper surface of the ski. This block 43 provides a direct connection between the rear binding element 4 and the upper surface of the ski.

La figure 6 représente une plaque 43, qui est constituée de deux éléments, un premier élément 40 situé au niveau de l'élément de fixation arrière 4, et une plate-forme 41 qui est solidarisée à l'élément 40 dans sa partie arrière, et qui s'étend au-dessus de la surface supérieure du ski jùsqu'au-delà de l'élément de fixation avant. L'élément 40 présente, vu de côté, la forme d'un oméga majuscule, avec une partie avant et une partie arrière solidarisées au ski dans des zones situées en avant et en arrière de l'élément de fixation arrière 4, et une partie médiane surélevée par rapport à la surface supérieure du ski, sur laquelle par ailleurs la plaque 41 est solidarisée. Un bloc de matériau élastiquement déformable 42 est situé entre cette zone et la surface supérieure du ski. Cette construction permet d'avoir un appui plus direct entre la plaque d'appui arrière 10 et le ski.FIG. 6 represents a plate 43, which consists of two elements, a first element 40 situated at the level of the rear fixing element 4, and a platform 41 which is secured to the element 40 in its rear part, and which extends above the upper surface of the ski up to beyond the front binding element. The element 40 has, seen from the side, the shape of a capital omega, with a front part and a rear part secured to the ski in areas located in front and behind the rear binding element 4, and a part raised median with respect to the upper surface of the ski, on which moreover the plate 41 is secured. A block of elastically deformable material 42 is located between this zone and the upper surface of the ski. This construction allows for more direct support between the rear support plate 10 and the ski.

La figure 7 illustre une variante de réalisation du mode d'exécution de la figure 6. Selon cette variante, la plaque 48 s'étend vers l'arrière au-delà de l'élément 40, où elle présente une extrémité 45 surélevée par rapport à la surface supérieure du ski. Un bloc de matériau élastiquement déformable 46 est monté en sandwich entre l'extrémité 45 de la plaque et la surface supérieure du ski. Ce bloc présente des propriétés d'amortissement selon une direction verticale. Son but est d'amortir les vibrations de l'extrémité arrière du ski, et en particulier celles dont la fréquence correspond au premier mode de flexion de la partie arrière du ski.FIG. 7 illustrates an alternative embodiment of the embodiment of FIG. 6. According to this alternative, the plate 48 extends rearwards beyond the element 40, where it has an end 45 raised relative to on the upper surface of the ski. A block of elastically deformable material 46 is sandwiched between the end 45 of the plate and the upper surface of the ski. This block has damping properties in a vertical direction. Its purpose is to dampen the vibrations of the rear end of the ski, and in particular those whose frequency corresponds to the first bending mode of the rear part of the ski.

La figure 8 représente une autre variante de réalisation, selon laquelle une plaque 63 est constituée de deux éléments assemblés entre eux, un élément arrière 64, et un élément avant 65. Au niveau de sa liaison avec l'élément arrière 64, l'élément 65 présente une lumière longitudinale 66. L'élément 64 est par ailleurs équipé d'un dispositif vis/écrou 67. De cette façon, les deux éléments peuvent coulisser l'un dans l'autre, et être assemblés de façon solidaire au moyen du système vis/écrou 67. On peut ainsi faire varier la longueur totale de la plaque 63.FIG. 8 represents another alternative embodiment, according to which a plate 63 consists of two elements assembled together, a rear element 64, and a front element 65. At its connection with the rear element 64, the element 65 has a longitudinal light 66. The element 64 is also equipped with a screw / nut device 67. In this way, the two elements can slide one inside the other, and be assembled in a solid manner by means of the screw / nut system 67. It is thus possible to vary the total length of the plate 63.

L'élément arrière 64 est solidarisé au ski dans sa partie arrière au moyen de vis qui viennent se placer dans les logements 68 et 69. En outre, de préférence, dans la partie centrale de l'élément arrière 64, on a prévu trois rondelles épaulées 70 qui sont logées dans trois orifices 71. Les rondelles 70 sont destinées à être solidarisées au ski par des vis, et les orifices 71 présentent selon une direction longitudinale une longueur légèrement supérieure à celle des rondelles 70, pour permettre un léger mouvement relatif selon une direction longitudinale. Les rondelles épaulées 70 ont principalement pour fonction de maintenir la partie centrale de l'élément arrière 64 à proximité de la surface supérieure du ski.The rear element 64 is secured to the ski in its rear part by means of screws which are placed in the housings 68 and 69. In addition, preferably, in the central part of the rear element 64, three washers have been provided. shoulders 70 which are housed in three orifices 71. The washers 70 are intended to be secured to the ski by screws, and the orifices 71 have in a longitudinal direction a length slightly greater than that of the washers 70, to allow a slight relative movement according to a longitudinal direction. The shoulder washers 70 mainly have the function of holding the central part of the rear element 64 near the upper surface of the ski.

L'élément arrière 64 présente également des orifices 72 pour l'assemblage de l'élément de fixation arrière. De préférence, à ce niveau, l'élément arrière 64 est surélevé par rapport à la surface supérieure du ski, et une couche interface 81 en matériau élastiquement déformable est intercalée entre l'élément arrière 64 et la surface supérieure du ski. Cette couche réalise un amortissement de l'appui arrière de la chaussure selon une direction verticale.The rear element 64 also has holes 72 for assembling the rear fixing element. Preferably, at this level, the rear element 64 is raised relative to the upper surface of the ski, and an interface layer 81 of elastically deformable material is interposed between the rear element 64 and the upper surface of the ski. This layer absorbs the rear support of the shoe in a vertical direction.

La cale 74 sur laquelle repose l'élément de fixation avant est constituée, dans l'exemple illustré, de deux éléments superposés, un élément inférieur 75, et un élément supérieur 76. Lorsque ces deux éléments sont montés l'un sur l'autre, ils définissent une ouverture longitudinale que traverse la partie avant de l'élément avant 65.The shim 74 on which the front fixing element rests is constituted, in the example illustrated, of two superimposed elements, a lower element 75, and an upper element 76. When these two elements are mounted one on the other , they define a longitudinal opening through which the front part of the front element 65 passes.

La partie supérieure 76 présente à sa surface supérieure une surface de support pour l'élément de fixation avant. En outre, dans l'exemple illustré, les vis d'assemblage de l'élément de fixation avant traversent de part en part la partie supérieure 76 et la partie inférieure 75 de la cale 74, et réalisent ainsi la solidarisation de l'ensemble au ski.The upper part 76 has at its upper surface a support surface for the front fixing element. In addition, in the example illustrated, the assembly screws of the front fixing element pass right through the upper part 76 and the lower part 75 of the wedge 74, and thus achieve the joining of the assembly to ski.

L'élément avant 65 présente donc dans sa partie avant une sorte de languette allongée qui traverse de part en part la cale 74 selon une direction longitudinale.The front element 65 therefore has in its front part a sort of elongated tongue which passes right through the wedge 74 in a longitudinal direction.

Ainsi que cela est visible dans la figure 9, l'élément avant 65 est relié aux parties supérieure et inférieure de la cale 74 par deux couches de colla 78 et 79. La colle qui est utilisée ici présente la propriété de travailler au cisaillement, en opposant une résistance élastique à une telle déformation. Ainsi, les couches de colla 78 et 79 permettent un mouvement relatif entre l'élément avant 65 et la cale 74, selon une direction longitudinale. Ce mouvement relatif peut avoir une amplitude de l'ordre de 5 millimètres vers l'avant, et les couches de colla, en s'étirant au cisaillement, opposent une résistance à ce mouvement.As can be seen in FIG. 9, the front element 65 is connected to the upper and lower parts of the wedge 74 by two layers of colla 78 and 79. The glue which is used here has the property of working in shear, in opposing an elastic resistance to such a deformation. Thus, the colla layers 78 and 79 allow relative movement between the front element 65 and the wedge 74, in a longitudinal direction. This relative movement can have an amplitude of the order of 5 millimeters towards the front, and the layers of colla, by stretching to the shear, oppose a resistance to this movement.

Le dispositif représenté dans la figure 8 présente également un berceau 80 qui vient se raccorder sur la partie supérieure 76 de la cale 74. Le berceau 80 guide l'élément avant 65 de la plaque 63 en arrière de la cale 74. Ainsi que cela est visible dans la figure 8, le berceau 80 est constitué d'une succession d'éléments sécables, que l'on coupe en fonction de la longueur totale que l'on souhaite donner à la plaque 63. Cette longueur est déterminée par l'écartement des éléments avant et arrière de fixation, et donc par la longueur de la chaussure.The device shown in FIG. 8 also has a cradle 80 which is connected to the upper part 76 of the wedge 74. The cradle 80 guides the front element 65 of the plate 63 behind the wedge 74. As is visible in Figure 8, the cradle 80 consists of a succession of breakable elements, which are cut according to the total length that one wishes to give to the plate 63. This length is determined by the spacing front and rear fastening elements, and therefore by the length of the boot.

Lors de la pratique du ski, il se produit un mouvement relatif entre la partie avant de la plaque 63 et la cale 74. Les couches de colle 78 et 79 sont alors sollicitées au cisaillement, et s'opposent à ce mouvement relatif.When skiing, there is a relative movement between the front part of the plate 63 and the wedge 74. The adhesive layers 78 and 79 are then stressed in shear, and oppose this relative movement.

La figure 10 représente schématiquement une autre variante de réalisation, selon laquelle la plaque 83 s'étend contre la surface supérieure du ski 84 sur la plus grande partie de sa longueur. Dans sa partie arrière, la plaque 83 est assemblée au ski par pincement entre le ski et l'embase de l'élément de fixation arrière 85. Dans sa partie avant, la plaque 83 traverse librement une cale 86 sur laquelle l'élément de fixation avant 87 est assemblé. La cale 86 est assemblée de façon solidaire au ski, et la plaque 83 peut coulisser librement à ce niveau selon une direction longitudinale.FIG. 10 schematically represents another alternative embodiment, according to which the plate 83 extends against the upper surface of the ski 84 over most of its length. In its rear part, the plate 83 is assembled to the ski by pinching between the ski and the base of the rear fixing element 85. In its front part, the plate 83 freely crosses a wedge 86 on which the fixing element before 87 is assembled. The wedge 86 is assembled integrally with the ski, and the plate 83 can slide freely at this level in a longitudinal direction.

En avant de l'élément de fixation avant 87, la plaque 83 présente une partie 88 surélevée, qui est assemblée à un support 89 par une couche de colle de même type de celle qui était utilisée dans la variante précédente.In front of the front fixing element 87, the plate 83 has a raised portion 88, which is assembled to a support 89 by a layer of adhesive of the same type as that which was used in the previous variant.

Lors de la pratique du ski, il se produit un mouvement relatif selon une direction longitudinale entre la partie surélevée 88 de la plaque 83, et le support 89 qui est solidaire du ski. Ce mouvement relatif longitudinal est contrarié par la couche de celle 90 qui travaille au cisaillement.When skiing, there is a relative movement in a longitudinal direction between the raised portion 88 of the plate 83, and the support 89 which is integral with the ski. This longitudinal relative movement is thwarted by the layer of that 90 which works on shearing.

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 que l'on pourrait inverser l'orientation des plaques 13, 48, 63, 83, et inverser le support des éléments de fixation de telle façon que ce soit l'élément de fixation avant qui soit solidaire de la plaque, et l'élément de fixation arrière qui soit relié de façon solidaire au ski par l'intermédiaire d'une cale. Dans ce cas, le bloc de matériau élastiquement déformable 17 pourrait être situé au-delà de l'élément de fixation arrière, et le cas échéant, un bloc de matériau élastiquement déformable du même type que le bloc 46 pourrait être situé au-delà de l'élément de fixation avant.In particular, it goes without saying that one could reverse the orientation of the plates 13, 48, 63, 83, and reverse the support of the fastening elements so that it is the front fastening element which is integral with the plate, and the rear fixing element which is integrally connected to the ski by means of a wedge. In this case, the block of elastically deformable material 17 could be located beyond the rear fixing element, and if necessary, a block of elastically deformable material of the same type as the block 46 could be located beyond the front fixing element.
