This holds an upper element (17) above the upper surface of the ski that forms a raised platform. The feet, vertical part and platform are made in one piece which is H-shaped. The outer ends of the feet rest on the lower edges and the vertical part passes through the upper surface of the ski.

Description

La présente invention a pour objet une planche de glisse sur neige, telle qu'un ski comportant un dispositif pour le montage d'une fixation d'une chaussure. La planche selon l'invention peut être un ski alpin, un ski de fond, un monoski ou un surf de neige.The present invention relates to a board for sliding on snow, such as a ski comprising a device for mounting a binding of a shoe. The board according to the invention can be an alpine ski, a cross-country ski, a monoski or a snowboard.

De façon traditionnelle, un ski alpin est équipé, sur sa face supérieure, d'une fixation pour une chaussure, cette fixation comportant le plus souvent une butée avant et une talonnière qui sont posées sur la face supérieure du ski et qui sont fixées par vissage dans le corps du ski.Traditionally, an alpine ski is equipped, on its upper face, with a binding for a boot, this binding generally comprising a front stop and a heel which are placed on the upper face of the ski and which are fixed by screwing in the body of the ski.

Un ski alpin est très schématiquement constitué d'un ensemble inférieur composé d'une semelle bordée de carres métalliques, et recouverte éventuellement d'un élément de renfort, et d'un ensemble supérieur composé au moins d'un noyau de remplissage, d'un élément de renfort et d'une enveloppe extérieure, soit en une partie sous forme de coque, soit en plusieurs parties composées de chants latéraux et d'un élément de protection supérieur.An alpine ski is very schematically made up of a lower assembly composed of a sole bordered with metal edges, and possibly covered with a reinforcing element, and of an upper assembly composed at least of a filling core, a reinforcing element and an external envelope, either in part in the form of a shell, or in several parts composed of lateral edges and of an upper protective element.

Dans le cas d'un ski à coque, la base de la coque est très souvent constituée de deux bords latéraux en appui sur une partie de leur largeur sur l'ensemble inférieur, c'est-à-dire soit directement sur les carres métalliques, soit sur l'élément de renfort recouvrant ces carres, soit enfin sur un film intermédiaire (film de colle ou film élastique).In the case of a hull ski, the base of the hull very often consists of two lateral edges resting on part of their width on the lower assembly, that is to say either directly on the metal edges , either on the reinforcing element covering these edges, or finally on an intermediate film (adhesive film or elastic film).

Pour assurer un bon guidage du ski, il est important que la transmission des efforts entre la chaussure du skieur et la carre d'un ski prenant appui sur la neige soit la plus directe possible. Or, le nombre des éléments de structure du ski par lesquels doivent transiter les forces entre la neige et la chaussure, constitue un facteur défavorable pour un bon guidage du ski.To ensure proper guidance of the ski, it is important that the transmission of forces between the skier's boot and the edge of a ski resting on the snow is as direct as possible. However, the number of structural elements of the ski through which the forces between the snow and the boot must pass, constitutes an unfavorable factor for good guidance of the ski.

Ce phénomène est amplifié lors de l'utilisation d'un dispositif de surélévation pour le montage de la fixation de la chaussure.This phenomenon is amplified when using an elevation device for mounting the binding of the shoe.

Du fait que les skis actuels sont plus étroits au patin, c'est-à-dire dans la zone de montage des fixations, que précédemment, la chaussure déborde de part et d'autre des parois latérales du ski. Il en résulte, lors d'une prise de carres sur une pente forte, que la chaussure peut prendre appui sur la surface de la neige, ce qui se traduit par un déséquilibre du skieur pouvant provoquer sa chute, ou tout au moins lui faire perdre du temps, ce qui est préjudiciable lors d'une compétition.Because the current skis are narrower at the waist, that is to say in the mounting area of the bindings, than previously, the boot extends beyond either side of the side walls of the ski. As a result, when grips on a steep slope, the shoe can bear on the surface of the snow, which results in an imbalance of the skier which can cause his fall, or at least make him lose time, which is detrimental during a competition.

Pour remédier à cet inconvénient, il a été imaginé de monter sur la face supérieure du ski une plaque de surélévation qui permet une angulation plus importante du ski par rapport à la neige avant que la chaussure ne prenne appui sur la surface de cette dernière.To overcome this drawback, it has been imagined to mount on the upper face of the ski an elevation plate which allows greater angulation of the ski with respect to the snow before the boot is supported on the surface of the latter.

Certaines plaques sont métalliques et fixées simplement sur la face supérieure du ski, formant uniquement des entretoises entre cette face supérieure et la platine de la butée ou de la talonnière.Some plates are metallic and fixed simply on the upper face of the ski, forming only spacers between this upper face and the plate of the stop or the heel piece.

Il est également connu de fixer, sur la face supérieure du ski, une plaque de surélévation constituée par une couche de matériau visco-élastique, collée sur le ski, et recouverte d'une plaque de contrainte. Différentes formes d'exécution reposant sur ce concept de base sont envisageables, comme décrit notamment dans les documents FR-A-2 638 651 et FR-A-2 664 823.It is also known to fix, on the upper face of the ski, an elevation plate constituted by a layer of visco-elastic material, bonded to the ski, and covered with a stress plate. Different embodiments based on this basic concept can be envisaged, as described in particular in documents FR-A-2 638 651 and FR-A-2 664 823.

Une telle solution permet d'assurer, outre la surélévation de la chaussure par rapport à la neige, une fonction de débridage de la chaussure par rapport au ski, et également une fonction d'amortissement, notamment par cisaillement de la couche de matériau visco-élastique entre la face supérieure du ski et la plaque de contrainte. Lors de la flexion d'un ski, il se produit un rapprochement de la butée et de la talonnière constitutives de la fixation qui exercent une pression sur la semelle de la chaussure se traduisant par une rigidification du ski dans cette zone et donc par une modification du comportement du ski par rapport à son comportement théorique. Il est donc intéressant d'éviter ce phénomène en assurant un certain débridage de l'ensemble chaussure-fixation par rapport au ski, redonnant à ce dernier une liberté de déformation.Such a solution ensures, in addition to the elevation of the boot relative to the snow, a function of unclamping the boot relative to the ski, and also a cushioning function, in particular by shearing the layer of viscous material. elastic between the upper face of the ski and the stress plate. When bending a ski, there is a rapprochement of the stop and the heel constituting the binding which exert pressure on the sole of the boot resulting in a stiffening of the ski in this area and therefore by a modification the behavior of the ski compared to its theoretical behavior. It is therefore advantageous to avoid this phenomenon by ensuring a certain unclamping of the boot-binding assembly with respect to the ski, giving the latter freedom of deformation.

Il est également connu par le document EP-A-0 490 044 de réaliser un ski constitué par un premier ensemble inférieur ou embase et un deuxième ensemble supérieur ou raidisseur fixé sur l'embase. Le raidisseur joue le rôle d'une plateforme de grande longueur sur laquelle est montée la fixation de la chaussure.It is also known from document EP-A-0 490 044 to make a ski consisting of a first lower assembly or base and a second upper assembly or stiffener fixed on the base. The stiffener plays the role of a very long platform on which the binding of the shoe is mounted.

Dans les solutions évoquées précédemment, la fixation est montée sur un élément lui-même fixé sur la face supérieure du ski. Or, pour assurer un meilleur guidage possible du ski, il est important que la transmission des efforts entre la carre d'un ski, prenant appui sur la neige, et la chaussure du skieur soit la plus directe possible. Or, l'interposition d'une plateforme de surélévation augmente le nombre des éléments par lesquels doivent transiter les forces entre la neige et la chaussure, ce qui constitue un facteur défavorable pour un bon guidage du ski.In the solutions mentioned above, the binding is mounted on an element itself fixed on the upper face of the ski. However, to ensure the best possible guidance of the ski, it is important that the transmission of forces between the edge of a ski, resting on the snow, and the skier's boot is as direct as possible. However, the interposition of a raised platform increases the number of elements per which must pass the forces between the snow and the boot, which constitutes an unfavorable factor for good guidance of the ski.

Le but de l'invention est de fournir un ski équipé d'un dispositif pour le montage de la fixation d'une chaussure assurant une transmission la plus directe possible des efforts entre la neige et la chaussure du skieur.The object of the invention is to provide a ski equipped with a device for mounting the binding of a boot ensuring the most direct possible transmission of the forces between the snow and the boot of the skier.

A cet effet, la planche de glisse sur neige qu'elle concerne, du type comprenant un ensemble inférieur composé d'une semelle bordée d'arêtes inférieures et éventuellement d'un élément de renfort, et un ensemble supérieur composé d'au moins un noyau de remplissage, d'un élément de renfort et d'une enveloppe extérieure, soit en une partie en forme de coque, soit en plusieurs parties composées de parois latérales et d'un élément supérieur de protection, comprend dans la partie centrale ou zone de patin :

  • au moins deux éléments inférieurs en forme de pattes disposés à l'intérieur du ski, situés de chaque côté de celui-ci et prenant appui sur l'ensemble inférieur, soit directement sur les arêtes inférieures, soit indirectement sur celles-ci, par l'intermédiaire d'un renfort ou d'un joint élastique,
  • au moins un élément supérieur qui, disposé au-dessus de la paroi supérieure du ski ou au niveau de cette paroi, forme une plateforme pour le montage de la fixation, et
  • au moins un élément de liaison entre les éléments inférieurs et l'élément supérieur, disposé à l'intérieur du ski et traversant la paroi supérieure de celui-ci.
To this end, the board for gliding on snow that it concerns, of the type comprising a lower assembly composed of a sole bordered by lower edges and optionally a reinforcing element, and an upper assembly composed of at least one filling core, a reinforcing element and an external envelope, either in the form of a shell, or in several parts composed of side walls and an upper protective element, comprises in the central part or zone skate:
  • at least two lower legs-shaped elements arranged inside the ski, located on each side of the latter and bearing on the lower assembly, either directly on the lower edges, or indirectly on these, by l '' through a reinforcement or an elastic joint,
  • at least one upper element which, placed above the upper wall of the ski or at the level of this wall, forms a platform for mounting the binding, and
  • at least one connecting element between the lower elements and the upper element, disposed inside the ski and passing through the upper wall thereof.

L'effort exercé par le pied du skieur est transmis directement au travers du dispositif composé de la plateforme, de la liaison et des pattes, aux arêtes inférieures du ski.The force exerted by the skier's foot is transmitted directly through the device composed of the platform, the link and the legs, to the lower edges of the ski.

Dans un tel cas, la force ne transite donc pas par la structure du ski, donc par les différents composants de celui-ci susceptibles de dénaturer cette force.In such a case, the force therefore does not pass through the structure of the ski, therefore through the various components of it capable of denaturing this force.

Selon une première possibilité, les éléments inférieurs, de liaison et la plateforme sont constitués par une pièce monobloc, cette pièce pouvant présenter, vue en coupe transversale, une forme générale de H couché, une forme générale de X, ou une forme générale de U renversé.According to a first possibility, the lower, connecting elements and the platform are constituted by a single piece, this piece being able to present, seen in cross section, a general shape of coated H, a general shape of X, or a general shape of U reversed.

Selon une autre possibilité, dans ce cas, les éléments inférieurs et de liaison sont constitués par une pièce monobloc, en forme générale de Y ou de T renversé, sur la face supérieure de laquelle est fixé, de façon amovible, l'élément supérieur formant plateforme.According to another possibility, in this case, the lower and connecting elements are constituted by a single piece, in the general shape of an Y or an inverted T, on the upper face of which is fixed, in a removable manner, the upper element forming platform.

Il est ainsi possible de rapporter la plateforme sur la face supérieure de la pièce monobloc, ce qui peut présenter des avantages, notamment en disposant de plateformes qui soient spécifiques aux différentes fixations susceptibles d'être montées sur le ski.It is thus possible to attach the platform to the upper face of the piece, which can have advantages, in particular by having platforms which are specific to the various bindings capable of being mounted on the ski.

Conformément à une possibilité, l'élément supérieur est monté sur l'élément de liaison avec interposition d'un élément amortisseur choisi parmi les matériaux visco-élastiques ou hyper-élastiques.According to one possibility, the upper element is mounted on the connecting element with the interposition of a damping element chosen from visco-elastic or hyper-elastic materials.

Selon les caractéristiques de comportement que l'on souhaite obtenir, les éléments inférieurs sont montés sur les arêtes inférieures ou sur un élément de renforcement recouvrant celles-ci, éventuellement avec interposition d'un matériau amortisseur.According to the behavioral characteristics which it is desired to obtain, the lower elements are mounted on the lower edges or on a reinforcement element covering these, possibly with the interposition of a damping material.

Suivant une forme d'exécution, les éléments inférieurs, le ou les éléments de liaison et l'élément supérieur s'étendent sur toute la longueur de montage de la fixation de la chaussure, l'élément supérieur formant une plateforme continue.According to one embodiment, the lower elements, the connecting element or elements and the upper element extend over the entire mounting length of the binding of the shoe, the upper element forming a continuous platform.

Selon une autre possibilité, dans le cas d'un ski alpin, les éléments inférieurs, le ou les éléments de liaison et l'élément supérieur sont disposés suivant deux sous-ensembles distincts décalés longitudinalement, dont celui avant sert au montage de la butée avant et dont celui arrière sert au montage de la talonnière de la fixation.According to another possibility, in the case of an alpine ski, the lower elements, the connecting element or elements and the upper element are arranged in two separate sub-assemblies offset longitudinally, the front one of which is used for mounting the front stop and the rear one is used for mounting the heel of the binding.

Conformément à une possibilité, le dispositif de montage de la fixation est asymétrique par rapport au plan longitudinal médian du ski. Par exemple, le nombre et la position longitudinale des différents éléments de liaison et inférieurs sont différents le long des deux côtés de la plateforme.According to one possibility, the device for mounting the binding is asymmetrical with respect to the median longitudinal plane of the ski. For example, the number and the longitudinal position of the different connecting and lower elements are different along the two sides of the platform.

Suivant une autre forme d'exécution, la plateforme est de longueur supérieure à celle des éléments inférieurs en forme de pattes, et dépasse longitudinalement de part et d'autre de ceux-ci.According to another embodiment, the platform is of greater length than that of the lower legs-shaped elements, and protrudes longitudinally on either side thereof.

Selon une autre forme d'exécution, les éléments de liaison et/ou les éléments inférieurs sont de longueurs différentes des deux côtés du ski.According to another embodiment, the connecting elements and / or the lower elements are of different lengths on the two sides of the ski.

La plateforme peut soit servir au montage d'une fixation standard, par exemple vissée, soit être constituée par une glissière formant l'embase recevant le corps de la fixation de chaussure, butée ou talonnière. Cette seconde solution permet de limiter le nombre des pièces constitutives de l'ensemble, puisqu'une seule pièce joue à la fois le rôle de plateforme et le rôle de la glissière longitudinale, dans laquelle est montée réglable, de façon connue, le corps de fixation.The platform can either be used for mounting a standard fixing, for example screwed, or be constituted by a slide forming the base receiving the body of the shoe binding, toe or heel. This second solution makes it possible to limit the number of constituent parts of the assembly, since a single part plays both the role of platform and the role of the longitudinal slide, in which is adjustable, in known manner, the body of fixation.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de ce ski :

Ce ski comporte, comme montré plus spécialement à la figure 2, une semelle de glissement 8, des carres longitudinales 9 disposées de part et d'autre de la semelle, des éléments latéraux de renforcement 10 formant les chants du ski, une paroi supérieure 12 éventuellement profilée, et un noyau de remplissage 13, par exemple en polyuréthanne.This ski comprises, as shown more particularly in FIG. 2, a sliding sole 8, longitudinal edges 9 arranged on either side of the sole, lateral reinforcing elements 10 forming the edges of the ski, an optionally profiled upper wall 12, and a filling core 13, for example made of polyurethane.

Suivant la caractéristique essentielle de l'invention, ce ski comprend, dans sa zone de patin, une pièce monobloc 14, en forme générale de X très ouvert, présentant deux éléments 15 en forme de pattes disposés à l'intérieur du corps du ski et en appui chacun sur une carre 9, une partie intermédiaire 16 de liaison disposée à l'intérieur du corps du ski et dépassant de la face supérieure du ski, et un élément supérieur 17 formant une plateforme continue sur laquelle sont fixées la butée 6 et la talonnière 7, par exemple par vissage.According to the essential characteristic of the invention, this ski comprises, in its skid area, a single piece 14, in the general shape of a very open X, having two elements 15 in the form of legs arranged inside the body of the ski and each bearing on an edge 9, an intermediate connecting portion 16 disposed inside the body of the ski and projecting from the upper face of the ski, and an upper element 17 forming a continuous platform on which the stop 6 and the heel piece 7, for example by screwing.

Les figures 3 et 4 représentent une variante d'exécution de ce ski, dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, le ski est équipé de deux dispositifs de surélévation distincts décalés longitudinalement, dont celui avant sert au montage de la butée 6 et dont celui arrière sert au montage de la talonnière de la fixation. Sur chaque carre 9, prend appui un élément 15, les éléments 15 étant prolongés par une partie intermédiaire 22 traversant la paroi supérieure 12 du ski. La plateforme 23 est fixée par des vis 21 sur la partie intermédiaire 22. Dans ce cas, la plateforme 23 présente une forme de glissière longitudinale, ouverte vers le haut, constituant l'embase pour le montage, de façon réglable, du corps de fixation, butée ou talonnière.Figures 3 and 4 show an alternative embodiment of this ski, in which the same elements are designated by the same references as above. In this case, the ski is equipped with two separate elevation devices offset longitudinally, the front one of which is used for mounting the stop 6 and the rear of which is used for mounting the heel of the binding. On each edge 9, an element 15 is supported, the elements 15 being extended by an intermediate portion 22 passing through the upper wall 12 of the ski. The platform 23 is fixed by screws 21 to the intermediate part 22. In this case, the platform 23 has a form of longitudinal slide, open upwards, constituting the base for the mounting, in an adjustable manner, of the fixing body. , toe or heel.

Dans la forme d'exécution représentée à la figure 5, sur chaque carre 9 prend appui un élément 20 d'épaisseur suffisante pour former lui-même un chant du ski dans la zone considérée, les éléments 20 étant prolongés vers le haut par un élément intermédiaire 22 qui dépasse de la face supérieure du ski, comme cela est montré notamment à la figure 3. Sur la face supérieure de l'élément intermédiaire 22 est fixée une plateforme 23a destinée au montage de la butée 6. Il en est exactement de même pour le montage de la talonnière 7. Il peut être noté que cette plateforme 23a peut être spécifique à la butée 6. Le montage peut être effectué par exemple à l'aide de vis non représentées. Dans la forme d'exécution représentée à la figure 5, il est prévu une couche 24 de matériau visco-élastique entre chaque élément inférieur 20 et la carre 9 correspondante, ainsi qu'une couche de matériau visco-élastique 25 entre l'élément intermédiaire 22 et la plateforme 23a.In the embodiment shown in Figure 5, on each edge 9 is supported an element 20 of sufficient thickness to itself form a ski edge in the area considered, the elements 20 being extended upwards by an element intermediate 22 which protrudes from the upper face of the ski, as shown in particular in Figure 3. On the upper face of the intermediate element 22 is fixed a platform 23a for mounting the stop 6. It is exactly the same for mounting the heel piece 7. It can be noted that this platform 23a can be specific to the stop 6. The mounting can be carried out for example using screws not shown. In the embodiment shown in FIG. 5, a layer 24 of visco-elastic material is provided between each lower element 20 and the corresponding edge 9, as well as a layer of visco-elastic material 25 between the intermediate element 22 and the platform 23a.

La figure 6 est une vue de détail de la figure 2 montrant un appui direct d'une patte 15 sur la face supérieure d'une carre 9. La figure 7 représente une variante dans laquelle, entre la patte 15 et la carre 9 est disposé un élément de renforcement inférieur 26.Figure 6 is a detail view of Figure 2 showing a direct support of a lug 15 on the upper face of a square 9. Figure 7 shows a variant in which, between the lug 15 and the edge 9 is disposed a lower reinforcing element 26.

La figure 8 représente une variante de la forme d'exécution de la figure 2, dans laquelle chaque patte 15 est reliée à l'élément supérieur 17 par une partie intermédiaire 27 située à l'intérieur du corps du ski, et à proximité de l'un des éléments latéraux 10 ou chants de celui-ci. L'élément supérieur 17 et la partie intermédiaire 27 déterminent un ensemble en forme de U renversé.FIG. 8 represents a variant of the embodiment of FIG. 2, in which each tab 15 is connected to the upper element 17 by an intermediate part 27 situated inside the body of the ski, and close to the 'one of the side elements 10 or edges thereof. The upper element 17 and the intermediate part 27 define an inverted U-shaped assembly.

La figure 9 représente la partie centrale ou zone de patin d'un autre ski, vu en coupe longitudinale médiane, dans lequel l'élément 17 constituant une plateforme est relié par un élément de liaison 16 à des éléments inférieurs 15a en forme de pattes, prenant appui sur les carres. Chaque élément 15a, rattaché à l'élément 16, est de longueur inférieure à la longueur de l'élément 17. L'élément 17 constituant une plateforme est donc monté en porte-à-faux par rapport aux pattes 15a.FIG. 9 represents the central part or skid zone of another ski, seen in median longitudinal section, in which the element 17 constituting a platform is connected by a connecting element 16 to lower elements 15a in the form of legs, building on the edges. Each element 15a, attached to the element 16, is of length less than the length of the element 17. The element 17 constituting a platform is therefore mounted in overhang relative to the legs 15a.

La figure 10 représente un dispositif selon l'invention seul, en perspective et de dessous. Dans ce cas, l'élément supérieur 17 constituant une plateforme est relié par l'intermédiaire d'élément de liaison 16, d'une part, à deux éléments inférieurs 15b en forme de pattes, en appui sur une première carre du ski et, d'autre part, à un élément inférieur 15c en forme de patte, en appui sur l'autre carre du ski.FIG. 10 represents a device according to the invention alone, in perspective and from below. In this case, the upper element 17 constituting a platform is connected by the intermediary of connecting element 16, on the one hand, to two lower elements 15b in the form of legs, bearing on a first edge of the ski and, on the other hand, to a lower element 15c in the shape of a tab, bearing on the other edge of the ski.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un ski équipé d'une plateforme, et dont la structure est telle que la transmission des efforts entre la neige et la fixation de la chaussure est effectuée le plus directement possible aux arêtes inférieures du ski.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a ski equipped with a platform, and the structure of which is such that the transmission of forces between the snow and the binding of the boot is carried out as directly as possible at the lower edges of the ski.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce ski, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que la plateforme (17) pourrait reposer sur la face supérieure du ski, ou être encastrée dans la paroi supérieure de celui-ci, ou que le ski pourrait être remplacé par une autre planche de glisse sur neige, telle que monoski ou surf, sans que l'on sorte pour autant du cadre de l'invention.As it goes without saying, the invention is not limited to the sole embodiments of this ski, described above by way of examples, on the contrary it embraces all variants. Thus in particular that the platform (17) could rest on the upper face of the ski, or be embedded in the upper wall thereof, or that the ski could be replaced by another board for sliding on snow, such as monoski or surf, without departing from the scope of the invention.
