Abstract

The upper surface of the ski is a layer of synthetic material (10) and its centre part is raised. The lateral edges of the ski (2,3) are lower than the thickness of the ski and form reinforcing bars. The lateral parts of the upper surface rest on the edges. A rigid platform (12) is an inverted U-shape, in cross-section, and its legs (14) rest on the edges. A notch (15), on each side of the upper layer, holds each leg and its length and width corresponds to the dimensions of the leg.

Description

La présente invention concerne une planche de glisse sur neige, telle qu'un ski, un monoski, un surf, etc. dont, au moins dans la zone de patin, la face de dessus est constituée par une couche de matière synthétique, cette couche de dessus n'étant pas plane et présentant, en section transversale, une partie centrale surélevée, en forme de coque, cette planche de glisse étant pourvue, de chaque côté, de chants auxiliaires de renforcement, de hauteur inférieure à celle de la planche dans une même section transversale de celle-ci, qui supportent le bord correspondant de ladite couche de dessus.The present invention relates to a board for gliding on snow, such as a ski, a monoski, a board, etc. of which, at least in the skid area, the top face is constituted by a layer of synthetic material, this top layer not being flat and having, in cross section, a raised central part, in the form of a shell, this gliding board being provided, on each side, with auxiliary reinforcement edges, of height less than that of the board in the same cross section thereof, which support the corresponding edge of said top layer.

Une planche de glisse telle que ci-dessus définie, est réalisée selon le concept dit «DUALTEC» (marque déposée par la société « SKIS ROSSIGNOL S.A. »).A gliding board as defined above, is produced according to the concept known as "DUALTEC" (trademark registered by the company "SKIS ROSSIGNOL S.A.").

Un ski de ce type fait par exemple l'objet des brevets et demandes de brevet FR-2.683.733, FR-2.683.734, FR-2.703.915 et FR-2.703.916, de la Demanderesse.A ski of this type is for example the subject of patents and patent applications FR-2,683,733, FR-2,683,734, FR-2,703,915 and FR-2,703,916, of the Applicant.

Une coupe transversale réalisée sur un ski de type «DUALTEC» montre qu'il comporte généralement :

  • une semelle inférieure de glissement, éventuellement bordée de chaque côté par des carres métalliques,
  • une éventuelle couche de renfort «inférieure» qui repose sur cette semelle de glissement,
  • un noyau qui peut par exemple être un noyau en bois ou un noyau en polyuréthanne obtenu préférentiellement par un procédé d'injection,
  • des chants latéraux auxiliaires, de hauteur inférieure à celle du ski, formant longerons de renforcement et positionnés de chaque côté de ce noyau,
  • une couche supérieure en matière plastique, ou couche de dessus, dont la face interne est éventuellement doublée, sur tout ou partie de sa largeur, d'une couche de renfort « supérieure », et qui recouvre le ski d'un bord à l'autre de celui-ci en venant s'appuyer, de part et d'autre de la planche, directement ou non, sur chacun desdits chants auxiliaires de renforcement.
A cross section made on a “DUALTEC” type ski shows that it generally includes:
  • a lower sliding sole, possibly bordered on each side by metal edges,
  • a possible “lower” reinforcement layer which rests on this sliding sole,
  • a core which can for example be a wooden core or a polyurethane core preferably obtained by an injection process,
  • auxiliary lateral edges, of height less than that of the ski, forming reinforcement beams and positioned on each side of this core,
  • an upper layer of plastic material, or top layer, the internal face of which is optionally doubled, over all or part of its width, with an “upper” reinforcing layer, and which covers the ski from edge to edge other of it by coming to bear, on either side of the board, directly or not, on each of said auxiliary reinforcement edges.

Ces chants auxiliaires de renforcement, qui sont sensiblement perpendiculaires à la surface de la semelle, ne font pas partie du concept, déjà très généralisé, des skis dits « à coque », puisque dans ce cas la couche de dessus est une coque qui prend appui directement sur les carres inférieures du ski. Dans le concept dit «DUALTEC», les chants ont pour effet d'améliorer l'efficacité du ski par rapport à un ski à coque ordinaire, par le fait qu'ils augmentent l'efficacité de la transmission des efforts, exercés par le skieur sur la surface supérieure du ski, aux carres métalliques inférieures, c'est-à-dire en fait à la surface de glisse.These auxiliary reinforcement edges, which are substantially perpendicular to the surface of the sole, are not part of the concept, already very generalized, of so-called “hull” skis, since in this case the top layer is a hull which is supported directly on the lower edges of the ski. In the concept called "DUALTEC", the sidewalls have the effect of improving the efficiency of the ski compared to an ordinary hull ski, by the fact that they increase the efficiency of the transmission of the forces exerted by the skier. on the upper surface of the ski, at the lower metal edges, that is to say in fact at the sliding surface.

L'invention se propose d'améliorer, sur un ski (ou autre planche de glisse sur neige) réalisé selon le concept «DUALTEC» précité, la transmission des impulsions du skieur à la neige en optimisant la liaison des fixations de la chaussure du skieur au ski ou autre planche de glisse sur neige.The invention proposes to improve, on a ski (or other snow gliding board) produced according to the above-mentioned “DUALTEC” concept, the transmission of the skier's impulses to snow by optimizing the binding of the bindings of the skier's boot skiing or other snowboarding.

Il est en effet essentiel, pour obtenir une bonne efficacité, que les efforts imprimés par la chaussure du skieur soient transmis le plus directement possible sur les arêtes latérales inférieures du ski.It is indeed essential, in order to obtain good efficiency, that the forces imparted by the skier's boot are transmitted as directly as possible to the lower lateral edges of the ski.

Il est connu, selon par exemple les documents FR-A-2.649.902 et FR-A-2.675.390, de prévoir, dans la zone de patin, une plaque ou plate-forme de surélévation des fixations de la chaussure et recevant ces fixations, cette plaque ou plate-forme pouvant être positionnée à distance de la surface supérieure du ski.It is known, for example according to documents FR-A-2,649,902 and FR-A-2,675,390, to provide, in the skate area, a plate or platform for raising the fastenings of the shoe and receiving these bindings, this plate or platform can be positioned at a distance from the upper surface of the ski.

Ces plaques ou plates-formes de surélévation des fixations s'avèrent aujourd'hui nécessaires en raison de la diminution, au niveau de la zone de patin , de la largeur des skis alpins dont une conséquence est alors un risque de ripage sur ski en virage serré, car la chaussure, qui déborde latéralement, vient alors toucher la neige à chaque prise de carre forte. Avec une surélévation suffisante, la chaussure ne risque pratiquement plus de venir frotter sur la neige à chaque inclinaison latérale importante du ski, et le ski peut donc être utilisé normalement, notamment en slalom.These plates or platforms for raising the bindings are nowadays necessary due to the reduction, at the level of the skate area, of the width of the alpine skis, a consequence of which is then a risk of skidding on ski when cornering. tight, because the shoe, which protrudes laterally, then comes to touch the snow with each grip of sharp edge. With sufficient elevation, the The shoe practically no longer runs the risk of coming to rub on the snow at each significant lateral tilt of the ski, and the ski can therefore be used normally, in particular in slalom.

Rappelons que l'on appelle « zone de patin » la zone intermédiaire, située entre l'avant et l'arrière de la planche, et sur laquelle sont montées les fixations de la chaussure.Recall that the “skate area” is called the intermediate area, located between the front and the back of the board, and on which the shoe bindings are mounted.

L'invention se rapporte donc à une planche de glisse sur neige dont, au moins dans la zone de patin, la face de dessus est constituée par une couche de matière synthétique, cette couche de dessus n'étant pas plane et présentant, en section transversale, une partie centrale surélevée, en forme de coque, cette planche comportant des chants latéraux auxiliaires de hauteur inférieure, dans une même section transversale, à celle de la planche, formant longerons de renforcement, et prévus au moins dans la zone de patin, cette couche de dessus venant s'appuyer par ses deux parties latérales de part et d'autre de la planche, directement ou non, sur chacun desdits chants auxiliaires de renforcement, cette planche de glisse étant équipée d'au moins une plate-forme rigide de réception et de surélévation des fixations de la chaussure, et étant caractérisée :

  • en ce que cette plate-forme rigide présente, en section transversale, une allure de U renversé et est conformée pour reposer, sur ses pieds et directement ou non, sur lesdits chants latéraux de renforcement,
  • et en ce que ladite couche de dessus de cette planche présente, de chaque côté et au niveau de chaque pied de ladite plate-forme, un décrochement positionné et dimensionné pour recevoir ce pied, chacun de ces décrochements étant de longueur sensiblement correspondante à celle du pied conjugué de la plate-forme et de largeur égale ou supérieure à la largeur de la base de ce pied qui ainsi repose sur la quasi-totalité du décrochement.
The invention therefore relates to a board for gliding on snow, the top face of which, at least in the skate area, consists of a layer of synthetic material, this top layer not being flat and having, in section transverse, a raised central part, in the shape of a shell, this board comprising auxiliary lateral edges of lower height, in the same cross section, than that of the board, forming reinforcement beams, and provided at least in the skate area, this top layer coming to rest by its two lateral parts on either side of the board, directly or not, on each of said auxiliary reinforcement edges, this gliding board being equipped with at least one rigid platform for receiving and raising the bindings of the shoe, and being characterized:
  • in that this rigid platform has, in cross section, a shape of an inverted U and is shaped to rest, on its feet and directly or not, on said lateral reinforcement edges,
  • and in that said top layer of this board has, on each side and at the level of each foot of said platform, a recess positioned and dimensioned to receive this foot, each of these recesses being of length substantially corresponding to that of the foot conjugate of the platform and of width equal or greater than the width of the base of this foot which thus rests on almost all of the recess.

Avantageusement, ladite plate-forme rigide comporte au moins deux pieds.Advantageously, said rigid platform comprises at least two feet.

Selon une forme de réalisation avantageuse, lesdits chants de renforcement présentent chacun, sur au moins une longueur limitée située dans la zone de patin et englobant lesdits décrochements, au moins une portion nettement plus large que le reste du chant.According to an advantageous embodiment, said reinforcing edges each have, over at least a limited length situated in the shoe zone and encompassing said recesses, at least a portion much wider than the rest of the edge.

Les chants de renforcement peuvent être soit localisés à la zone de patin, cette dernière englobant les pieds de ladite plate-forme, soit ils peuvent s'étendre sur toute la longueur portante de la planche.The reinforcement edges can either be located at the skate area, the latter encompassing the feet of said platform, or they can extend over the entire bearing length of the board.

Rappelons que la « longueur portante » d'une planche de glisse sur neige est la longueur de sa surface de contact avec le sol lorsque l'utilisateur est debout sur sa planche de glisse.Recall that the "bearing length" of a snow gliding board is the length of its contact surface with the ground when the user is standing on his board.

L'invention sera bien comprise, et ses avantages et autres caractéristiques ressortiront, lors de la description suivante d'un exemple non limitatif de réalisation, en référence au dessin schématique annexé, dans lequel :

En se reportant à l'ensemble des figures 1 à 5, il s'agit donc ici d'un ski de piste 1 ou « ski alpin » qui est du type dit «DUALTEC» et qui est pourvu, de chaque côté du ski et dans la zone de patin, d'un chant latéral de renforcement 2, 3 reposant sur la carre inférieure respective 4, 5.Referring to all of FIGS. 1 to 5, it is therefore here a piste ski 1 or “alpine ski” which is of the so-called “DUALTEC” type and which is provided, on each side of the ski and in the skate area, a lateral reinforcement edge 2, 3 resting on the respective lower edge 4, 5.

Ce ski est totalement symétrique par rapport à son plan longitudinal médian 6, et il comporte, visibles dans une même section transversale, :

  • une semelle inférieure de glissement 7 bordée de chaque côté par des carres métalliques 4, 5 :
  • une couche de renfort inférieur 8 qui repose sur la semelle de glissement 7,
  • un noyau de polyuréthanne 9 obtenu par un procédé d'injection des composés d'une mousse de polyuréthanne,
  • bordant ce noyau de part et d'autre, au niveau de la zone de patin: les deux chants latéraux auxiliaires 2, 3, de hauteur inférieure à celle du ski et formant, conformément à l'enseignement de FR-A-2.683.733 et suivants précités, longerons de renforcement et reposant sur les carres correspondantes 4 et 5 ,
  • un revêtement supérieur constitué par une couche de matière synthétique et formant, dans la zone de patin, une coque 10, dont la face interne est doublée d'une couche de renfort supérieur 11, cette coque venant s'appuyer de part et d'autre, par deux ailes latérales X et Y, sur les deux chants de renforcement 2 et 3 dans la zone médiane du ski et sur les carres 4 et 5 dans les parties avant et arrières de ce ski.
This ski is completely symmetrical with respect to its median longitudinal plane 6, and it comprises, visible in the same cross section,:
  • a lower sliding sole 7 bordered on each side by metal edges 4, 5:
  • a lower reinforcement layer 8 which rests on the sliding sole 7,
  • a polyurethane core 9 obtained by a process for injecting the compounds of a polyurethane foam,
  • bordering this core on both sides, at the level of the skate area: the two auxiliary lateral edges 2, 3, of height less than that of the ski and forming, in accordance with the teaching of FR-A-2,683,733 and following aforementioned, reinforcement beams and resting on the corresponding edges 4 and 5,
  • an upper covering constituted by a layer of synthetic material and forming, in the skid zone, a shell 10, the internal face of which is doubled with an upper reinforcement layer 11, this shell coming to bear on either side , by two lateral wings X and Y, on the two reinforcement edges 2 and 3 in the middle area of the ski and on the edges 4 and 5 in the front and rear parts of this ski.

Le ski 1 est, selon l'invention, prévu pour recevoir, dans sa zone de patin, une plate-forme rigide 12 de réception et de surélévation des fixations 13A, 13B de la chaussure du skieur.The ski 1 is, according to the invention, designed to receive, in its skid area, a rigid platform 12 for receiving and raising the bindings 13A, 13B of the skier's boot.

Cette plate-forme 12 est monolithique, ne comportant de ce fait qu'une seule plaque supérieure. Elle a une section transversale en forme de U renversé et une allure générale de table basse à quatre pieds 14, chacun de ces pieds venant s'encastrer dans quatre décrochements femelle conjugués 15 de la coque du ski 1, de façon à reposer fermement, dans ces décrochements ou encoches 15, sur les portées correspondantes 20 et 30 des chants de renforcement, ces derniers étant élargis en conséquence sur la longueur de ces encoches. Comme on le voit sur les figures 3 et 5, la largeur L1 des portées 20 et 30 des chants de renforcement 2 et 3 a, sur la longueur L2 de ces décrochements, 15, une valeur égale ou supérieure à celle L0 du bord correspondant et sensiblement plat et horizontal de la coque 10 (doublée des son renfort 11), par lequel elle repose sur le chant latéral de renforcement correspondant 2 ou 3. Chacun de ces décrochements 15 est donc de longueur L2 sensiblement correspondante à celle du pied conjugué 14 de la plate-forme et de largeur L0 au moins égale à la largeur de la base de ce pied 14 qui ainsi repose à plat sur la quasi-totalité du décrochement 15.This platform 12 is monolithic, therefore comprising only a single upper plate. It has an inverted U-shaped cross section and a general appearance of a four-legged coffee table 14, each of these legs fitting into four conjugate female recesses 15 of the ski shell 1, so as to rest firmly, in these recesses or notches 15, on the corresponding spans 20 and 30 reinforcement edges, the latter being widened accordingly over the length of these notches. As can be seen in FIGS. 3 and 5, the width L1 of the spans 20 and 30 of the reinforcement edges 2 and 3 has, over the length L2 of these recesses, 15, a value equal to or greater than that L0 of the corresponding edge and substantially flat and horizontal of the shell 10 (doubled by its reinforcement 11), by which it rests on the corresponding lateral reinforcement edge 2 or 3. Each of these recesses 15 is therefore of length L2 substantially corresponding to that of the conjugate leg 14 of the platform and of width L0 at least equal to the width of the base of this foot 14 which thus rests flat on almost all of the step 15.

Il est souhaité que la plate-forme unique 12 représente au moins trois pieds 14 par lesquels elle repose sur les ailes de la coque et donc sur les chants correspondants 2 et 3, car elle est ainsi plus souple et plus légère qu'une classique plate-forme à ailes latérales continues. Cette plate-forme monolithique 12 permet, de par sa conformation, de débrider le ski par rapport à la fixation de la chaussure en permettant de garantir une distance constante entre la butée avant et la talonnière arrière de cette fixation.It is desired that the single platform 12 represents at least three feet 14 by which it rests on the wings of the hull and therefore on the corresponding edges 2 and 3, because it is thus more flexible and lighter than a conventional flat -form with continuous side wings. This monolithic platform 12, by virtue of its conformation, unleashes the ski with respect to the binding of the boot, making it possible to guarantee a constant distance between the front stop and the rear heel of this binding.

Selon Figure 5, la plate-forme rigide 12 est fixée sur les chants 2, 3 au moyen de vis 16 après l'opération de mise en position dans les quatre encoches 15. Elle ne repose alors que sur ces chants 2, 3 par ses pieds 14 (avec ici interposition des deux couches de matière constituées par la coque 10 et par son renfort 11), car ceux-ci sont suffisamment hauts pour qu'il soit alors ménagé un espace libre 17 entre la surface supérieure 18 du ski et la face inférieure de cette plate-forme 12. L'effort du skieur s'exerce alors, via la plate-forme 12, ses pieds 14, et les chants 2, 3, directement sur les carres 4, 5, ce qui est le but principal de l'invention.According to Figure 5, the rigid platform 12 is fixed to the edges 2, 3 by means of screws 16 after the positioning operation in the four notches 15. It then rests only on these edges 2, 3 by its feet 14 (here with the interposition of the two layers of material constituted by the shell 10 and by its reinforcement 11), because these are high enough so that a free space 17 is then created between the upper surface 18 of the ski and the underside of this platform 12. The effort of the skier is then exerted, via the platform 12, his feet 14, and the edges 2, 3, directly on the edges 4, 5, which is the goal principal of the invention.

L'épaisseur et la forme de la plate-forme 12 sont choisies telles que les vis 31 de maintien des fixations 13A, 13B ne pénètrent pas dans la coque 10.The thickness and the shape of the platform 12 are chosen such that the screws 31 for holding the fasteners 13A, 13B do not penetrate into the shell 10.

Pour fixer les idées, la longueur L2 de chacun des quatre décrochements 15 a avantageusement une valeur de l'ordre de 3 centimètres, et il en est bien évidemment de même pour les dimensions correspondantes de chaque pied 14.To fix the ideas, the length L2 of each of the four recesses 15 advantageously has a value of the order of 3 centimeters, and it is obviously the same for the corresponding dimensions of each foot 14.

La distance longitudinale D entre les deux paires de décrochements en regard correspond à un espace, situé dans la zone de patin, qui est avantageusement de l'ordre de 40 centimètres.The longitudinal distance D between the two pairs of facing hooks corresponds to a space, located in the skid area, which is advantageously of the order of 40 centimeters.

Comme il va de soi, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit, et de nombreuses variantes d'exécution sont envisageables.It goes without saying that the invention is not limited to the embodiment which has just been described, and numerous alternative embodiments are possible.

C'est ainsi par exemple que la plate-forme 12 pourrait être elle-même l'embase, classiquement réalisée sous forme de glissière, de la fixation de la chaussure, cette plate-forme et glissière recevant donc le corps de la butée avant et/ou de la talonnière.Thus, for example, the platform 12 could itself be the base, conventionally produced in the form of a slide, for fixing the shoe, this platform and slide therefore receiving the body of the front stop and / or the heel piece.

On sait en effet qu'une fixation traditionnelle comporte généralement une embase formant glissière, et donc à section en forme de « U fermé », cette embase permettant, par glissement, au corps de la fixation (butée avant et/ou arrière) de se déplacer longitudinalement vers l'avant ou vers l'arrière pour en particulier régler la fixation en fonction de la pointure de la chaussure du skieur. Selon cette particularité de l'invention, c'est donc cette plate-forme de surélévation 12 qui sert également de glissière.It is known in fact that a traditional fixing generally comprises a base forming a slide, and therefore with a section in the shape of a "closed U", this base allowing, by sliding, the body of the fixing (front and / or rear stop) to be move longitudinally forward or backward in particular to adjust the binding according to the shoe size of the skier. According to this feature of the invention, it is therefore this elevation platform 12 which also serves as a slide.

C'est ainsi aussi que l'existence des portées élargies des chants de renforcement 2, 3 n'est pas absolument indispensable et, dans une forme de réalisation simplifiée de l'invention, les pieds 14 de la plate-forme 12 pourraient être d'une largeur (à la base) qui soit inférieure ou préférentiellement sensiblement égale à celle L1 des chants de renforcement 2 et 3.It is thus also that the existence of the enlarged spans of the reinforcement edges 2, 3 is not absolutely essential and, in a simplified embodiment of the invention, the feet 14 of the platform 12 could be d 'a width (at the base) which is less or preferably substantially equal to that L1 of the reinforcement edges 2 and 3.

C'est ainsi aussi que, selon Figure 6 et Figure 8, les portions renforcées 20, 30 des chants 2, 3 pourraient, au niveau de chaque décrochement 15, s'étendre à cet endroit d'une seule pièce (20+30) sur toute la largeur du ski 1.This is also how, according to Figure 6 and Figure 8, the reinforced portions 20, 30 of the edges 2, 3 could, at each recess 15, extend at this location in one piece (20 + 30) over the entire width of the ski 1.

C'est ainsi également qu'il pourrait aussi être prévu, selon Figure 7 et Figure 8, une couche viscoélastique 27, 28 d'amortissement des vibrations, sur chacun des chants renforcés 20, 30 au niveau des décrochements 15 et préférentiellement sous chaque pied 14 de la plate-forme (avec interposition éventuelle des couches 10 et 11 comme on le voit sur le dessin).This is also how it could also be provided, according to FIG. 7 and FIG. 8, a viscoelastic layer 27, 28 for damping vibrations, on each of the reinforced edges 20, 30 at the level of the recesses 15 and preferably under each foot. 14 of the platform (with possible interposition of layers 10 and 11 as seen in the drawing).

Au lieu de reposer sur les chants 2 et 3, qu'il s'agisse de parties élargies 20 et 30 ou non, par l'intermédiaire des couches 10 (coque) et 11 (renfort supérieur), les pieds 14 de la plate-forme 12 pourraient aussi soit reposer directement sur ces chants 2 et 3, et alors les couches 10 et 11 seraient absentes à cet endroit, soit reposer sur ces chants par l'intermédiaire d'une seule de ces deux couches, 10 ou 11, et alors l'autre couche, 11 ou 12 serait alors absente à cet endroit, ce qui n'empêcherait d'ailleurs nullement de prévoir néanmoins d'interposer une couche viscoélastique entre chaque pied 14 et le chant 2 ou 3 sur lequel il repose, directement ou indirectement donc.Instead of resting on the edges 2 and 3, whether enlarged parts 20 and 30 or not, via the layers 10 (shell) and 11 (upper reinforcement), the feet 14 of the platform shape 12 could also either rest directly on these edges 2 and 3, and then the layers 10 and 11 would be absent at this location, or rest on these edges via only one of these two layers, 10 or 11, and then the other layer, 11 or 12 would then be absent at this location, which would in no way prevent from nevertheless providing for interposing a viscoelastic layer between each leg 14 and the edge 2 or 3 on which it rests, directly or indirectly therefore.

Dans une variante de réalisation de l'invention, l'espace 17 qui est ménagé entre la plate-forme 12 et le dessus 18 du ski pourrait être comblé par une couche de matériau viscoélastique au lieu d 'être constitué par une simple couche d'air.In an alternative embodiment of the invention, the space 17 which is formed between the platform 12 and the top 18 of the ski could be filled with a layer of viscoelastic material instead of being constituted by a simple layer of air.

Cette plate-forme 12 pourrait avoir six pieds 14 au lieu de quatre, ou même plus, et il serait alors prévu un nombre égal de décrochements 15 dans le ski 1.This platform 12 could have six feet 14 instead of four, or even more, and an equal number of recesses 15 would then be provided in the ski 1.

Selon une autre variante, la plate-forme 14 pourrait être dissymétrique par rapport à son axe longitudinal, c'est-à-dire par rapport au plan longitudinal médian 6 du ski, et il en serait éventuellement alors de même, de manière conjuguée, pour les éventuelles portions élargies 20, 30 des chants 2, 3 ainsi qu'alors pour leurs décrochements conjugués 15 de la coque 10.According to another variant, the platform 14 could be asymmetrical with respect to its longitudinal axis, that is to say with respect to the median longitudinal plane 6 of the ski, and it would possibly be the same then, in a combined manner, for the possible enlarged portions 20, 30 of the edges 2, 3 as well as then for their combined recesses 15 of the shell 10.

En particulier, la plate-forme 12 pourrait avoir moins de pieds 14 du côté de la carre interne du ski, ou plus généralement du côté intérieur du ski lorsque les deux skis sont chaussés aux pieds du skieur, que l'autre côté (ou côté extérieur), ceci afin de débrider encore plus le ski en flexion. Par exemple, la plate-forme 12 pourrait n'avoir que trois pieds 14, dont un pied du côté intérieur du ski (carre interne) et deux pieds du côté extérieur du ski (carre externe).In particular, the platform 12 could have fewer feet 14 on the side of the inner edge of the ski, or more generally on the inner side of the ski when the two skis are put on at the feet of the skier, than the other side (or side outside), this in order to unclamp the ski even more in flexion. For example, the platform 12 could have only three feet 14, including one foot on the inside of the ski (internal edge) and two feet on the outside of the ski (external edge).

Le ski considéré n'est pas obligatoirement un ski muni de carres métalliques. Il pourrait très bien s'agir d'un ski ne possédant par de carres sur ses arêtes latérales inférieures, comme c'est la cas actuellement pour une grande majorité des skis de fond.The ski considered is not necessarily a ski provided with metal edges. It could very well be a ski that does not have edges on its lower lateral edges, as is currently the case for a large majority of cross-country skis.

La plate-forme 12 est ici une plate-forme métallique, par exemple en alliage d'Aluminium. Elle pourrait aussi être en une autre matière rigide, telle que du matériau composite (tissu de verre-époxy, polyuréthanne armé,...).The platform 12 is here a metallic platform, for example made of aluminum alloy. It could also be made of another rigid material, such as composite material (glass-epoxy fabric, reinforced polyurethane, etc.).

Au lieu d'être monolithique, la plate-forme 2 de réception des fixations 13A, 13B pourrait être réalisée en deux parties, dont une partie avant recevant la partie avant 13A de la fixation, ou « butée », et une partie arrière recevant la partie arrière 13B de la fixation, ou « talonnière ». Préférentiellement dans un tel cas, la partie avant de la plate-forme 12 est alors prévue pour être ancrée dans les chants 2, 3 du ski par des vis de fixations 16, ou analogue, selon la figure 5 par exemple, tandis que la partie arrière de cette plate-forme 12 comporte, à l'instar de la figure 7, des patins 27, 28 en matière viscoélastique sous chacun de ses pieds 14, ces couches viscoélastiques 27, 28 étant d'une part collées sous leurs pieds respectifs 14, et étant d'autre part respectivement collées sur les deux ailes réceptrices X, Y de la coque 10, sur lesquelles elles reposent respectivement. Cette disposition permet d'éviter encore plus efficacement le bridage du ski.Instead of being monolithic, the platform 2 for receiving the bindings 13A, 13B could be made in two parts, including a front part receiving the front part 13A of the binding, or "stop", and a rear part receiving the rear part 13B of the binding, or "heel piece". Preferably in such a case, the front part of the platform 12 is then provided to be anchored in the edges 2, 3 of the ski by fixing screws 16, or the like, according to FIG. 5 for example, while the part rear of this platform 12 comprises, like FIG. 7, pads 27, 28 of viscoelastic material under each of its feet 14, these viscoelastic layers 27, 28 being on the one hand glued under their respective feet 14 , and being on the other hand respectively glued to the two receiving wings X, Y of the shell 10, on which they rest respectively. This arrangement makes it possible to more effectively avoid the clamping of the ski.

Une autre réalisation conforme à l'invention et elle aussi très efficace pour éviter le bridage du ski est représentée aux figures 9 à 11.Another embodiment in accordance with the invention and also very effective in preventing the clamping of the ski is shown in FIGS. 9 to 11.

Selon cette forme de réalisation, la plate-forme 12, qui est monolithique, ne possède des pieds 14 qu'à l'avant de cette plate-forme, par lesquels elle repose sur les chants de renforcement 2, 3 comme toutes les plates-formes 12 précédemment décrites.According to this embodiment, the platform 12, which is monolithic, has feet 14 only at the front of this platform, by which it rests on the reinforcement edges 2, 3 like all the platforms. 12 forms previously described.

En revanche, elle ne possède pas de pieds à l'arrière où elle repose alors sur la surface supérieure 18 du ski par l'intermédiaire d'au moins une cale viscoélastique 32 qui s'étend préférentiellement sur toute la largeur de cette surface supérieure 18 et qui est collée à la fois sur cette surface 18 et sous la plate-forme 12.On the other hand, it does not have feet at the rear where it then rests on the upper surface 18 of the ski by means of at least one viscoelastic wedge 32 which preferably extends over the entire width of this upper surface 18 and which is glued both to this surface 18 and under the platform 12.

Enfin, la figure 12 illustre une dernière forme de réalisation qui se différencie de celles selon les figures 1 à 8 par le fait que la plate-forme 12, qui est monolithique, ne possède des pieds 14 que dans sa partie longitudinale, médiane 12M (il y est prévu par exemple deux pieds dans l'exemple non limitatif représenté, mais il pourrait aussi y être prévu quatre pieds), de sorte que sa partie avant 12A et sa partie arrière 12B sont toutes deux en porte-à-faux par rapport à cette partie médiane 12M, et sont situées à une faible distance « e » au-dessus de la surface supérieure 18 du ski.Finally, FIG. 12 illustrates a final embodiment which differs from those according to FIGS. 1 to 8 by the fact that the platform 12, which is monolithic, has feet 14 only in its longitudinal part, median 12M ( there is provided for example two feet in the nonlimiting example shown, but it could also be provided four feet), so that its front part 12A and its rear part 12B are both cantilevered relative to to this middle part 12M, and are located a short distance "e" above the upper surface 18 of the ski.
