Abstract
Description
La présente invention a pour objet un ski, et notamment un ski alpin comportant des chants et une coque supérieure.The subject of the present invention is a ski, and in particular an alpine ski comprising edges and an upper shell.
Un ski traditionnel comprend une surface inférieure constituée par une semelle bordée de carres longitudinales, sur lesquelles reposent des chants rigides, par exemple en ABS ou en stratifié phénolique. Ces chants, qui s'étendent sur toute la hauteur du ski sont généralement perpendiculaires à la semelle de celui-ci. Entre les chants, est disposé le noyau, qui peut être réalisé de différentes façons, éventuellement avec des éléments de renforcement, le noyau étant lui-même recouvert par une paroi supérieure, qui repose également sur la paroi supérieure des chants.A traditional ski comprises a lower surface constituted by a sole bordered by longitudinal edges, on which rest rigid edges, for example ABS or phenolic laminate. These edges, which extend over the entire height of the ski, are generally perpendicular to the sole thereof. Between the edges, the core is arranged, which can be produced in different ways, possibly with reinforcing elements, the core itself being covered by an upper wall, which also rests on the upper wall of the edges.
L'avantage d'un tel ski est que la rigidité des chants assure une excellente transmission des efforts exercés par le skieur sur la surface de la neige.The advantage of such a ski is that the rigidity of the edges ensures excellent transmission of the forces exerted by the skier on the surface of the snow.
Il est de plus en plus fréquent, pour des raisons esthétiques, et pour des raisons d'industrialisation de la fabrication des skis, de réaliser des skis en forme, c'est-à-dire des skis de section non rectangulaire, possédant une coque formant la face supérieure et les faces latérales du ski, ces faces latérales étant éventuellement inclinées sur au moins une partie de leur hauteur. Dans une telle hypothèse, le noyau peut être réalisé en mousse de matière synthétique, par exemple de polyuréthanne, qui possède d'excellentes propriétés de stabilité dans le temps, tout en étant d'un poids peu élevé.It is more and more common, for aesthetic reasons, and for reasons of industrialization of the manufacture of skis, to produce shaped skis, that is to say skis of non-rectangular section, having a shell. forming the upper face and the lateral faces of the ski, these lateral faces possibly being inclined over at least part of their height. In such a case, the core can be made of synthetic material foam, for example polyurethane, which has excellent properties of stability over time, while being of low weight.
Toutefois, ce dernier type de ski, illustré notamment par les documents FR 2 611 518, US 3 272 522 et FR 2 522 976, ne donne pas toujours entière satisfaction du fait que la transmission des efforts sur les carres à partir de la face supérieure du ski n'est pas réalisée de façon suffisamment ferme, compte tenu de l'absence de chants et de l'inclinaison des parois latérales. Cette transmission se fait seulement par des feuilles de renforcement de la coque, qui sont plaquées contre les flancs inclinés et qui prennent un appui ponctuel sur les carres. Ces skis possèdent donc des caractéristiques de comportement qui ne peuvent pas satisfaire totalement aux critères d'exigence requis, notamment en compétition, où la précision de guidage souhaitée pour les skis, impose une transmission aussi parfaite que possible des efforts depuis la face supérieure du ski vers les carres.However, this latter type of ski, illustrated in particular by the
Généralement, les coques constituant les skis modernes comprennent un élément supérieur de protection supportant le décor du ski, recouvrant une armature en tissu de verre contenant éventuellement du carbone ou des fibres aramide constituant le renfort supérieur du ski. Ce tissu de renfort pourrait, dans la partie supérieure correspondant à la face supérieure du ski, n'être constitué que de fibres unidirectionnelles. Toutefois, il est impératif que les rabats, constituant les faces latérales du ski, comportent des fibres orientées dans le sens de la trame, nécessaires à l'obtention d'une résistance, notamment en torsion, suffisante, et procurant un appui sur les carres. Il est donc nécessaire d'utiliser des tissus comportant une chaîne et une trame, même si cette structure est surdimensionnée pour la réalisation de la surface supérieure du ski qui doit assurer principalement une résistance en flexion simple du ski.Generally, the hulls constituting modern skis comprise an upper protective element supporting the decoration of the ski, covering a glass fabric frame possibly containing carbon or aramid fibers constituting the upper reinforcement of the ski. This reinforcing fabric could, in the upper part corresponding to the upper face of the ski, be made up only of unidirectional fibers. However, it is imperative that the flaps, constituting the lateral faces of the ski, include fibers oriented in the direction of the weft, necessary to obtain sufficient resistance, in particular in torsion, and providing support on the edges . It is therefore necessary to use fabrics comprising a warp and a weft, even if this structure is oversized for the production of the upper surface of the ski which must mainly provide resistance in simple bending of the ski.
Le but de l'invention est de fournir un ski, dans lequel la transmission des efforts depuis la face supérieure du ski vers les carres soit réalisée dans les meilleurs conditions possibles, et qui comporte une coque formant sa face supérieure et au moins une partie de ses faces latérales, afin de posséder de bonnes qualités esthétiques.The object of the invention is to provide a ski, in which the transmission of forces from the upper face of the ski to the edges is carried out under the best possible conditions, and which comprises a shell forming its upper face and at least part of its side faces, in order to have good aesthetic qualities.
A cet effet, le ski qu'elle concerne, comprenant un noyau de remplissage, par exemple en mousse de polyuréthanne, et une face inférieure équipée d'une semelle de glissement centrale et délimitée par deux carres métalliques longitudinales, ainsi que des feuilles de renforcement et de décoration, est caractérisé en ce qu'il comprend des éléments de renforcement longitudinaux qui, prenant appui chacun sur une carre et formant les chants du ski, servent à l'appui et à la fixation des bords de la coque, la hauteur des éléments de renforcement étant sensiblement égale, dans au moins une zone du ski, à la hauteur de celui-ci, tandis que dans au moins une autre zone du ski, la hauteur des éléments de renforcement est inférieure à la hauteur du ski, et la coque présente au moins une partie inclinée de haut en bas et de l'intérieur vers l'extérieur.To this end, the ski it concerns, comprising a filling core, for example made of polyurethane foam, and a lower face equipped with a central sliding sole and delimited by two longitudinal metal edges, as well as reinforcing sheets and decoration, is characterized in that it comprises longitudinal reinforcing elements which, each bearing on an edge and forming the edges of the ski, serve to support and fix the edges of the hull, the height of the reinforcing elements being substantially equal, in at least one zone of the ski, to the height thereof, while in at least one other zone of the ski, the height of the reinforcing elements is less than the height of the ski, and the shell has at least one part inclined from top to bottom and from the inside to the outside.
Ce ski possède des éléments de renforcement longitudinaux formant chants, qui prennent appui sur les carres et qui assurent une bonne transmission depuis la face supérieure du ski vers les carres. En outre, le fait que la paroi supérieure du ski soit constituée par une coque confère à celui-ci d'intéressantes qualités esthétiques, permet une industrialisation de sa fabrication, et permet de disposer, dans certaines zones du ski, de parois latérales pour partie inclinées, ce qui permet d'adapter les caractéristiques du ski au type d'utilisation envisagée.This ski has longitudinal reinforcing elements forming edges, which bear on the edges and which ensure good transmission from the upper face of the ski to the edges. In addition, the fact that the upper wall of the ski is constituted by a shell gives the latter interesting aesthetic qualities, allows a industrialization of its manufacture, and makes it possible to have, in certain areas of the ski, side walls for part inclined, which makes it possible to adapt the characteristics of the ski to the type of use envisaged.
Selon une première forme d'exécution, dans la zone de patin, la hauteur d'au moins un élément de renforcement est inférieure à la hauteur du ski, la coque présentant au moins une partie inclinée correspondante, tandis que dans au moins une des zones d'extrémité, la hauteur d'au moins un élément de renforcement est sensiblement égale à la hauteur du ski.According to a first embodiment, in the skate zone, the height of at least one reinforcing element is less than the height of the ski, the hull having at least one corresponding inclined part, while in at least one of the zones end, the height of at least one reinforcing element is substantially equal to the height of the ski.
Dans ces zones d'extrémité, spatule et talon, la section du ski correspond à celle d'un ski traditionnel, tandis que dans la zone de patin, ce ski comporte, sur une partie de sa hauteur, et au moins de l'un de ses côtés, une partie inclinée appartenant à la coque.In these end zones, tip and heel, the cross section of the ski corresponds to that of a traditional ski, while in the skate zone, this ski comprises, over part of its height, and at least one on its sides, an inclined part belonging to the hull.
Selon une autre forme d'exécution, dans la zone de patin, la hauteur d'au moins un élément de renforcement est sensiblement égale à la hauteur du ski, tandis que dans au moins une des zones d'extrémités, la hauteur d'au moins un élément de renforcement est inférieure à la hauteur du ski, la coque présentant au moins une partie inclinée correspondante.According to another embodiment, in the skate zone, the height of at least one reinforcing element is substantially equal to the height of the ski, while in at least one of the end zones, the height of at least one reinforcing element is less than the height of the ski, the shell having at least one corresponding inclined part.
Dans sa zone de patin, ce ski présente une section correspondant à celle d'un ski traditionnel, tandis que dans ses zones d'extrémité, spatule et talon, le ski comporte au moins sur l'un de ses bords une surface inclinée résultant de la présence de la coque. Ce dernier type de ski permet un bon accrochage sur neige dure, compte tenu de la bonne transmission des efforts exercés sur la surface de la neige vers la surface supérieure du ski, dans la zone de patin, et un bon comportement en neige poudreuse, compte tenu de l'effilement des zones d'extrémité, spatule et talon.In its skate area, this ski has a section corresponding to that of a traditional ski, while in its end zones, tip and heel, the ski comprises at least on one of its edges an inclined surface resulting from the presence of the hull. This last type of ski allows a good grip on hard snow, taking into account the good transmission of the forces exerted on the snow surface towards the upper surface of the ski, in the skate area, and a good behavior in powder snow, account given the taper of the end zones, tip and heel.
Avantageusement, le tissu de renforcement supérieur de la coque est constitué par des fibres unidirectionnelles orientées uniquement dans le sens longitudinal du ski, ce qui constitue un facteur d'économie, sans nuire aux qualités du ski.Advantageously, the upper reinforcement fabric of the shell is made up of unidirectional fibers oriented only in the longitudinal direction of the ski, which constitutes a saving factor, without harming the qualities of the ski.
Les deux éléments de renforcement peuvent être symétriques par rapport à un plan médian longitudinal du ski ou dissymétriques par rapport à ce plan. C'est ainsi qu'un ski peut être dissymétrique, et les deux skis constitutifs d'une même paire présenter une symétrie par rapport à un plan médian longitudinal passant entre les deux skis, les deux éléments de renforcement appartenant aux deux skis, disposés au niveau des bords en regard de ceux-ci, possédant une hauteur sensiblement égale à la hauteur du ski, sur au moins une partie de la longueur de celui-ci, tandis que les éléments de renforcement correspondant aux deux bords extérieurs possèdent une hauteur qui varie, sur la longueur du ski, par rapport à la hauteur totale du ski. Cela permet de privilégier l'accrochage du ski en ayant un élément de renforcement efficace sur au moins une partie de sa longueur au niveau du bord d'appui intérieur, tout en affinant le bord extérieur, grâce à la présence d'au moins une partie inclinée de la coque, pour faciliter les évolutions en neige poudreuse.The two reinforcing elements can be symmetrical with respect to a longitudinal median plane of the ski or asymmetrical with respect to this plane. Thus a ski can be asymmetrical, and the two skis constituting the same pair have symmetry with respect to a longitudinal median plane passing between the two skis, the two reinforcing elements belonging to the two skis, arranged at the edges opposite them, having a height substantially equal to the height of the ski, over at least part of the length thereof, while the reinforcing elements corresponding to the two outer edges have a height which varies, over the length of the ski, relative to the total height of the ski. This makes it possible to favor the attachment of the ski by having an effective reinforcing element over at least part of its length at the level of the internal support edge, while refining the external edge, thanks to the presence of at least one part. inclined hull, to facilitate evolutions in powder snow.
Conformément à une forme d'exécution de ce ski, chaque partie inclinée de la coque se termine, vers le bas, par un retour parallèle au plan de la semelle, qui prend appui sur la face supérieure d'un élément de renforcement formant chant.According to an embodiment of this ski, each inclined part of the shell ends, downwards, by a return parallel to the plane of the sole, which bears on the upper face of a reinforcing element forming a song.

Ce ski comprend une face inférieure équipée d'une semelle de glissement 5 délimitée par deux carres métalliques 6, sur lesquelles sont en appui deux renforts longitudinaux 7 formant les chants du ski. La partie supérieure du ski est constituée par une coque 8, par exemple en matière synthétique thermoformée contre la face intérieure de laquelle est plaquée une bande de renfort 11, l'âme du ski étant constituée par un noyau de remplissage 9, par exemple en mousse de polyuréthanne.The ski shown in FIGS. 1 to 4 comprises, in a known manner, a
Dans la forme d'exécution représentée aux figures 1 à 4, chaque renfort longitudinal possède, dans la zone de patin, une hauteur sensiblement inférieure à la hauteur du ski, et sert de support à la coque 8 qui comprend un retour 10, sensiblement parallèle à la semelle 5, prenant appui sur le renfort 7 correspondant, ce retour étant prolongé par une partie 12 inclinée de haut en bas et de l'intérieur vers l'extérieur, cette partie inclinée 12 étant elle-même raccordée à la face supérieure 13, qui est parallèle à la semelle 5.In the embodiment represented in FIGS. 1 to 4, each longitudinal reinforcement has, in the skate area, a height substantially less than the height of the ski, and serves as a support for the
Dans les zones d'extrémité 3 et 4, la hauteur de chaque renfort longitudinal 7 est sensiblement égale à la hauteur du ski, de telle sorte que la coque 8 prend directement appui, par sa face supérieure plane 13, sur les faces supérieures des renforts longitudinaux 7.In the
Cette structure permet de disposer d'un ski qui possède une section rectangulaire dans ses zones d'extrémité, et qui possède des parois latérales pour partie inclinée dans sa zone de patin.This structure makes it possible to have a ski which has a rectangular section in its end zones, and which has side walls for part inclined in its skate zone.
Dans une telle structure la hauteur du renfort longitudinal 7 peut être constante sur toute la longueur du ski.In such a structure, the height of the

Dans ce ski, la hauteur de chaque élément de renforcement 17 formant chant est sensiblement égale à la hauteur du ski dans la zone de patin de celui-ci, comme montré notamment à la figure 8. Au contraire, dans les zones d'extrémité du ski, la hauteur de chaque élément de renforcement 17 est sensiblement inférieure à la hauteur du ski. Dans ces conditions, la coque 18 comporte, dans ses zones d'extrémité, deux retours 20, sensiblement parallèles à la semelle 5, prenant appui sur les faces supérieures des deux éléments de renforcement 17. Les deux retours 20 sont reliés à la face supérieure 23 de la coque par deux parties 22 inclinées de haut en bas et de l'intérieur vers l'extérieur. Dans la partie centrale du ski ou zone de patin, la face supérieure 23 de la coque prend appui directement sur les faces supérieures des deux éléments de renforcement 17.In this ski, the height of each reinforcing
Les deux skis, qui viennent d'être décrits ci-dessus, permettent d'allier les avantages des skis à chants en matière de performance, et les avantages des skis à coque en matière d'industrialisation et de qualité de finition.The two skis, which have just been described above, make it possible to combine the advantages of edge skis in terms of performance, and the advantages of hull skis in terms of industrialization and quality of finish.
