Description
L'invention concerne un ski prévu pour la pratique du ski alpin, ainsi qu'une paire de skis.The invention relates to a ski provided for the practice of alpine skiing, and a pair of skis.
De façon connue, un ski comprend un noyau central qui est entouré de couches de renfort et qui comprend sur le dessous une semelle de glisse avec deux carres, et sur le dessus une couche de décor.In known manner, a ski comprises a central core which is surrounded by layers of reinforcement and which comprises on the underside a gliding sole with two edges, and on top a layer of decoration.
Ces dernières années la technique de ski a évolué avec la technique dite du "carving". La ligne de cotes des skis a été accentuée, la longueur des skis a été diminuée. En virage, au lieu de faire porter son poids principalement sur un ski, le skieur garde ses appuis sur les deux skis qu'il maintient écartés.In recent years the ski technique has evolved with the so-called "carving" technique. The ski sidecut was emphasized, the length of the skis was decreased. In turns, instead of putting his weight mainly on a ski, the skier keeps his support on the two skis he keeps apart.
Pour tenir compte de cette nouvelle technique de ski, on a pensé à donner au ski une structure asymétrique.To take into account this new ski technique, we thought to give the ski an asymmetrical structure.
Ainsi, par exemple la demande de brevet
Ce mode de construction donne des résultats satisfaisants, toutefois il influe principalement sur la trajectoire du ski.This mode of construction gives satisfactory results, however it influences mainly the ski's trajectory.
La demande de
Un but de l'invention est de proposer un ski de construction asymétrique qui est encore mieux adapté à la pratique du ski selon la technique de "carving".An object of the invention is to provide an asymmetric ski construction which is even better suited to the practice of skiing according to the technique of "carving".
A cet effet, l'invention propose un ski comprenant un noyau central, un sous-ensemble de renfort inférieur situé sous le noyau et reposant sur une semelle de glisse qui est bordée par deux carres latérales, et un sous-ensemble de renfort supérieur situé sur le dessus du noyau, et recouvert par une couche de décoration, chacun des sous-ensembles de renfort comprenant une ou plusieurs couches, l'une au moins des couches de renfort supérieur ayant une portion centrale recouvrant le dessus du noyau et au moins un pan latéral redescendant en direction d'une carre. Le ski est caractérisé par le fait qu'au moins une des couches de renfort du sous-ensemble de renfort supérieur a une structure asymétrique au niveau de ses pans latéraux le long d'au moins une partie de sa longueur.For this purpose, the invention proposes a ski comprising a central core, a lower reinforcement subassembly located under the core and resting on a gliding soleplate which is bordered by two lateral edges, and an upper reinforcement subassembly located on the top of the core, and covered by a decorative layer, each of the reinforcing subassemblies comprising one or more layers, at least one of the upper reinforcing layers having a central portion covering the top of the core and at least one side pan descending towards a square. The ski is characterized in that at least one of the reinforcing layers of the upper reinforcement subassembly has an asymmetrical structure at its side panels along at least part of its length.
De cette façon, on introduit une asymétrie dans la structure de la coque du ski. Cette coque assurant la transmission des efforts entre le dessus du ski et les carres, on peut gérer de façon différente l'appui du skieur sur l'une et l'autre des carres.In this way, asymmetry is introduced into the structure of the ski hull. This hull ensuring the transmission of forces between the top of the ski and the edges, it is possible to manage differently the support of the skier on one and the other of the edges.

Le ski représenté en
De façon connue, le ski présente une partie centrale 2 prévue pour recevoir les éléments de retenue de la chaussure, et des parties avant et arrière 4 et 5 qui se terminent respectivement par la spatule 6 et le talon 7.In known manner, the ski has a
De façon connue, le ski présente une surface inférieure de glisse 8 qui est bordée par deux carres 9 et 10, une surface supérieure 11 de décoration et des chants latéraux 13 et 14 entre la surface supérieure et les carres latérales.In known manner, the ski has a lower sliding
En section, la structure du ski comprend un noyau central 6. Le noyau est en tout matériau approprié, notamment en bois ou en mousse injectée ou usinée, par exemple en mousse de polyuréthane. Ainsi que cela est connu ses dimensions en section peuvent varier sur la longueur du ski, et il peut être formé de plusieurs éléments juxtaposés transversalement et/ou verticalement.In section, the structure of the ski comprises a
Le noyau 6 repose sur un sous-ensemble de renfort inférieur 15, qui lui-même repose sur une semelle de glisse 16. La semelle de glisse 16 fournit la surface inférieure de glisse 8.The
Selon le mode de réalisation illustré, le sous-ensemble de renfort inférieur 15 comprend deux couches de renfort, une couche inférieure en fibres imprégnées de résine 17 et une couche de renfort métallique 18, par exemple en alliage d'aluminium. Les couches de renfort peuvent être formées de plusieurs sous-couches.According to the illustrated embodiment, the
Un sous-ensemble de renfort supérieur 19 est disposé au-dessus du noyau 6. Il présente de préférence le même type de structure que le sous-ensemble inférieur, avec une couche de renfort métallique 20 et une couche 21 de renfort en fibres imprégnées de résine.An upper reinforcing
L'ensemble est recouvert d'une couche externe 23 qui est décorée et fournit la surface supérieure 11 de décoration.The assembly is covered with an
Comme cela a été dit précédemment, sur le dessus et le dessous du noyau les sous-ensembles de renfort ont de préférence le même type de structure pour assurer une stabilité de la cambrure du ski.As mentioned above, on the top and the bottom of the core the reinforcing subassemblies preferably have the same type of structure to ensure stability of the camber of the ski.
Selon une particularité de l'invention la structure du ski n'est pas la même le long des deux flancs latéraux du ski. On sait que des efforts importants traversent ces zones en particulier lorsque le skieur prend des virages. Le fait d'avoir une structure différente permet de gérer différemment l'appui du ski sur ses carres externe et interne, et donc de gérer différemment l'appui des skis intérieur et extérieur au virage.According to a feature of the invention the structure of the ski is not the same along the two lateral flanks of the ski. It is known that significant efforts cross these areas especially when the skier takes turns. The fact of having a different structure makes it possible to manage differently the support of the ski on its outer and inner edges, and thus to manage differently the support of the skis inside and outside the turn.
Selon le mode de réalisation illustré la couche de renfort métallique 20 a une portion centrale 20c qui couvre le dessus du noyau et un pan latéral 20a de cette couche descend le long d'un seul flanc du ski, le flanc 14. De l'autre côté la couche de renfort s'arrête à la jonction entre le dessus du noyau et le flanc opposé 13. La couche de renfort en fibres 21 a une portion centrale 21c qui couvre le dessus du noyau et un pan latéral 21 a descend le long de l'autre flanc 13 du ski. La couche de renfort 21 ne couvre pas le flanc opposé 14.According to the illustrated embodiment the
Ces deux couches rejoignent les carres 9 et 10. Ainsi le ski présente une structure en caisson hybride avec deux couches de renfort superposées sur le dessus et le dessous du noyau, un renfort métallique de liaison le long d'un flanc et un renfort de liaison en fibres sur l'autre.These two layers join the
La structure semblable du ski sur le dessus et le dessous du noyau assure une stabilité du cambre du ski. Le pan latéral métallique donne une accroche puissante, le pan latéral en fibres permet de doser l'accrochage du ski sur la neige.The similar structure of the ski on the top and the bottom of the core ensures stability of the camber of the ski. The metallic side panel gives a powerful grip, the lateral pan in fibers makes it possible to dose the hanging of the ski on the snow.
Naturellement pour une paire de skis les renforts latéraux sont disposés avec une symétrie de miroir au niveau de leurs pans latéraux. Dans ces conditions, de préférence les pans latéraux métalliques se trouvent sur l'extérieur des skis et les pans en fibres sur l'intérieur. Toutefois ceci n'est pas limitatif et on peut aussi faire l'inverse.Naturally for a pair of skis the lateral reinforcements are arranged with mirror symmetry at their side panels. Under these conditions, preferably the metal side panels are on the outside of the skis and the fiber panels on the inside. However this is not limiting and we can also do the opposite.
La
En variante, on pourrait avoir un rabat seulement sur une des couches de renfort.Alternatively, one could have a flap only on one of the reinforcing layers.
Au lieu d'être prolongée par un rabat, la portion centrale 36c, 37c des couches de renfort 36, 37 peut être arrêtée en retrait du bord latéral 35b, 35c du noyau 35 sur leur côté qui n'est pas prolongé par un pan latéral. Ceci est illustré dans la
Selon le mode de construction de la
L'autre couche de renfort 41 est asymétrique, elle a une portion centrale 41c qui couvre la face supérieure du noyau 38 et un pan 41a qui descend le long d'un seul flanc, le flanc 44.The other reinforcing
Selon le mode de réalisation illustré sur le dessus du noyau la couche de renfort asymétrique est placée au-dessous de la couche symétrique. Ceci n'est pas limitatif et une disposition inverse peut également convenir.According to the embodiment illustrated on the top of the core, the asymmetrical reinforcing layer is placed below the symmetrical layer. This is not limiting and a reverse arrangement may also be suitable.
Dans ces différentes constructions, les couches de renfort peuvent être de même nature, notamment des couches en fibres imprégnées de résine, ou bien elles peuvent être de nature différente, notamment une couche de renfort en fibres et une couche de renfort métallique ou encore deux couches de fibres de nature différente, par exemple de verre, de carbone ou de fibres aramides noyées dans une matrice époxy. On peut utiliser également des couches dont les fibres ont des orientations différentes, par exemple une orientation longitudinale et une orientation transversale, ou encore des orientations obliques par rapport à la direction longitudinale du ski, de part et d'autre de la direction longitudinale définie par le ski, ou encore des couches de densité différente.In these different constructions, the reinforcing layers may be of the same type, in particular resin impregnated fiber layers, or they may be of a different nature, in particular a fiber reinforcement layer and a metallic reinforcement layer or still two layers of fibers of different nature, for example glass, carbon or aramid fibers embedded in an epoxy matrix. It is also possible to use layers whose fibers have different orientations, for example a longitudinal orientation and a transverse orientation, or else oblique orientations with respect to the longitudinal direction of the ski, on either side of the longitudinal direction defined by the ski, or even layers of different density.
La
Comme dans les cas précédents les couches 48, 49 et 50 sont de même nature ou de nature différente selon leur matière, leur densité et/ou l'orientation des fibres.As in the previous cases, the
Selon la variante d'exécution illustrée en
Le mode de réalisation de la
Comme dans le cas précédent, le sous-ensemble de renfort supérieur 85 a une structure asymétrique. Selon le mode de réalisation illustré le sous-ensemble 85 comprend deux couches 87 et 88 ayant des pans latéraux 87a, 88a qui redescendent en direction de chacune des entretoises 80, 81. D'autres structures asymétriques pourraient naturellement convenir.As in the previous case, the
En variante le ski pourrait avoir une entretoise d'un côté seulement du ski.Alternatively the ski could have a spacer on one side of the ski.
Le long de la direction longitudinale du ski, l'asymétrie de la structure du ski peut être homogène ou hétérogène.Along the longitudinal direction of the ski, the asymmetry of the ski structure may be homogeneous or heterogeneous.
La
La
La
Un tel renfort a une structure symétrique dans la partie arrière et la partie centrale, et une structure asymétrique dans la partie avant. Une disposition inversée pourrait également convenir.Such a reinforcement has a symmetrical structure in the rear part and the central part, and an asymmetrical structure in the front part. An inverted arrangement might also be suitable.
Pour le renfort 98 représenté dans la

Dans la
Enfin la
D'autres modes de découpage des renforts sont encore possibles.Other ways of cutting reinforcements are still possible.
Lorsque le sous-ensemble supérieur est formé de plusieurs couches de renfort superposées, chacune des couches peut être réalisée selon un même mode de découpage, ou selon des modes de découpage différents.When the upper subassembly is formed of several superposed reinforcing layers, each of the layers can be made according to the same cutting mode, or according to different cutting modes.
Selon l'invention il est suffisant qu'une des couches de renfort supérieur présente une asymétrie de structure au niveau de ses pans latéraux.According to the invention it is sufficient that one of the upper reinforcement layers has a structural asymmetry at its side panels.
Naturellement l'invention n'et pas limitée aux modes de réalisation qui ont été décrits, et d'autres variantes sont possibles.Naturally, the invention is not limited to the embodiments that have been described, and other variants are possible.
Egalement, au lieu de couvrir toute la longueur du ski, les couches de renfort supérieur, ou une partie d'entre elles, pourraient ne couvrir qu'une partie de celle-ci.Also, instead of covering the entire length of the ski, the upper reinforcement layers, or part of them, could cover only a part of it.
