Description

La présente invention a pour objet une planche de glisse sur neige comportant un renfort supérieur.The present invention relates to a board for sliding on snow with upper reinforcement.

Une planche de glisse sur neige comprend un ensemble inférieur constitué par une semelle de glissement bordée par deux arêtes métalliques longitudinales appelées carres. Sur les carres reposent les parois latérales du ski, qui sont disposées de part et d'autre d'un noyau central. L'ensemble inférieur peut comprendre au-dessus de la semelle un ou plusieurs éléments de renforcement se présentant sous forme d'une lame métallique ou sous forme d'une couche de fibres imprégnées de résine. Une planche de glisse comprend enfin un ensemble supérieur comprenant une paroi supérieure en dessous de laquelle peut se trouver, en fonction des caractéristiques du ski, un renfort supérieur constitué par une lame métallique et/ou une couche de fibres imprégnées de résine.A snow gliding board includes a lower assembly consisting of a sliding sole bordered by two metal edges longitudinal called edges. On the edges lie the side walls ski, which are arranged on either side of a central core. The lower assembly may include one or more above the sole several reinforcing elements in the form of a strip metallic or in the form of a layer of fibers impregnated with resin. A gliding board finally comprises an upper assembly comprising a upper wall below which can be found, depending on the characteristics of the ski, an upper reinforcement constituted by a blade metallic and / or a layer of fibers impregnated with resin.

Une telle structure est générale et s'applique à différents types de planche de glisse, notamment des planches de glisse de section rectangulaire comportant des parois latérales constituées par des éléments indépendants appelés chants, ou des planches de glisse dont la paroi supérieure et les parois latérales sont constituées au moins en partie par un même élément appelé coque.Such a structure is general and applies to different types gliding boards, in particular section gliding boards rectangular with side walls formed by elements independent called edges, or boards of gliding whose wall upper and the side walls are formed at least in part by a same element called shell.

Le document DE 20 25 622 concerne un ski comportant, de façon localisée, des éléments de renforcement sous forme de plaques métalliques.Document DE 20 25 622 relates to a ski comprising, localized, reinforcing elements in the form of plates metal.

Le document DE 23 46 417 concerne un ski comportant des éléments de renforcement se présentant sous forme de feuilles, soit métalliques, soit de matière synthétique renforcée de fibres. Dans ce cas encore, ces éléments de renforcement ne se trouvent que sur une partie de la surface du ski.Document DE 23 46 417 relates to a ski comprising reinforcing elements in the form of sheets, or metallic, or synthetic material reinforced with fibers. In that case again, these reinforcing elements are only found on part of the surface of the ski.

Il est également connu de réaliser des skis comprenant un renfort supérieur, c'est-à-dire situé du côté de la paroi supérieure du ski, au-dessus du noyau, comprenant une lame métallique et une couche de fibres imprégnées de résine. La couche de fibres imprégnées de résine s'étend sur toute la largeur du ski, tandis que la lame métallique comporte des bords longitudinaux qui sont situés légèrement en retrait des bords longitudinaux du ski, mais s'étendent parallèlement à ceux-ci.It is also known to make skis comprising a upper reinforcement, that is to say located on the side of the upper wall of the ski, above the core, comprising a metal blade and a layer of resin-impregnated fibers. The resin-impregnated fiber layer extends over the entire width of the ski, while the metal blade has longitudinal edges which are slightly set back from the edges longitudinal of the ski, but extend parallel to them.

Une telle lame métallique peut être constituée, par exemple, à base d'un alliage d'aluminium, tel que celui connu sous le nom commercial de Zycral. La couche de fibres imprégnées de résine peut être obtenue à partir de fibres de même nature, ou de natures différentes, telles que des fibres de verre, de carbone, ou d'aramide.Such a metal blade can be made, for example, to based on an aluminum alloy, such as that known under the trade name from Zycral. The resin-impregnated fiber layer can be obtained at from fibers of the same kind, or of different kinds, such as glass, carbon or aramid fibers.

Une lame métallique constitutive d'un renfort supérieur possède un caractère anisotrope, c'est-à-dire que ses propriétés mécaniques sont constantes dans tous les sens. En ce qui concerne la couche fibreuse, elle possède un caractère isotrope, dans la mesure où il est possible de réaliser un dosage différent des fibres dans le sens longitudinal et dans le sens transversal.A metal blade constituting an upper reinforcement has an anisotropic character, that is to say that its mechanical properties are constant in every way. As for the fibrous layer, it has an isotropic nature, insofar as it is possible to carry out a different dosage of fibers in the longitudinal direction and in the direction transverse.

Il faut également noter que la lame métallique et la couche de fibres imprégnées de résine ne possèdent pas les mêmes propriétés. C'est ainsi que la lame métallique possède une bonne raideur en torsion, tandis que la couche de fibres imprégnées de résine possède de moins bonnes caractéristiques de raideurs en torsion, mais de bonnes caractéristiques de résistance en flexion.It should also be noted that the metal blade and the layer of resin-impregnated fibers do not have the same properties. It is as well as the metal blade has a good torsional stiffness, while that the layer of fibers impregnated with resin has worse characteristics of torsional stiffness, but good characteristics of flexural strength.

C'est ainsi que, pour les lames métalliques et couches de fibres imprégnées de résine déjà utilisées dans la constitution de skis, le module de flexion E1 de la lame métallique est sensiblement deux fois supérieur au module de flexion E2 de la couche de fibres, tandis que le module de torsion G1 de la lame métallique est sensiblement cinq fois supérieur au module de torsion G2 de la couche de fibres imprégnées de résine.Thus, for the metal blades and layers of fibers impregnated with resin already used in the constitution of skis, the flexural modulus E 1 of the metallic blade is substantially twice greater than the flexural modulus E 2 of the layer of fibers, while the torsional modulus G 1 of the metal strip is substantially five times greater than the torsional modulus G 2 of the layer of fibers impregnated with resin.

Le but de l'invention est de fournir un renfort supérieur pour planche de glisse sur neige, permettant d'optimiser les performances de celle-ci, en fonction du comportement recherché, en tenant compte des caractéristiques spécifiques des matériaux : lame métallique et couche de fibres imprégnées de résine, constitutifs du renfort supérieur de la planche.The object of the invention is to provide superior reinforcement for snow gliding board, to optimize the performance of this, depending on the behavior sought, taking into account the specific characteristics of the materials: metal blade and layer of fibers impregnated with resin, constituting the upper reinforcement of the board.

A cet effet, le renfort supérieur qu'elle concerne, du type comprenant une lame métallique et une couche de fibres imprégnées de résine superposées, est caractérisée en ce qu'il s'étend de façon continue sur sensiblement toute la longueur utile du ski et en ce que les quantités respectives et/ou les formes respectives et/ou les positionnements respectifs par rapport à la fibre neutre de la lame métallique et de la couche de fibres varient différemment sur la longueur du ski.To this end, the upper reinforcement that it concerns, of the type comprising a metal blade and a layer of fibers impregnated with superimposed resin, is characterized in that it extends continuously over substantially the entire useful length of the ski and in that the quantities and / or the respective shapes and / or the positions respective with respect to the neutral fiber of the metal strip and the layer fibers vary differently over the length of the ski.

Contrairement aux skis connus dans l'art antérieur, le renfort supérieur n'est pas un renfort localisé ponctuellement, mais s'étend sur toute la longueur de la planche, les caractéristiques de comportement de cette dernière étant obtenues en faisant varier les quantités et/ou formes et/ou positionnements par rapport à la fibre neutre de l'un des composants par rapport à l'autre composant.Unlike skis known in the prior art, the reinforcement superior is not a localized reinforcement punctually, but extends over the entire length of the board, the behavior characteristics of the latter being obtained by varying the quantities and / or forms and / or positioning in relation to the neutral fiber of one of the components compared to the other component.

Suivant une forme d'exécution de cette planche de glisse, la couche de fibres imprégnées de résine s'étend sur sensiblement toute la largeur de la planche et sur sensiblement toute la longueur de la planche, tandis que la largeur de la lame métallique varie sur la longueur de la planche.According to an embodiment of this gliding board, the layer of resin-impregnated fibers extends over substantially the entire width of the board and over substantially the entire length of the board, while the width of the metal blade varies along the length of the board.

Il est ainsi possible de faire varier le comportement d'une planche en adaptant les largeurs respectives de la lame métallique et de la couche de fibres imprégnées de résine sur la longueur de la planche.It is thus possible to vary the behavior of a board by adapting the respective widths of the metal blade and the layer of resin-impregnated fibers along the length of the board.

Suivant une première possibilité, la largeur de la lame métallique est maximale dans la zone avant de la planche, c'est-à-dire sensiblement de la largeur de celle-ci, est minimale dans la zone centrale ou zone de patin, c'est-à-dire inférieure à la largeur de la planche, et augmente dans la zone arrière de la planche.According to a first possibility, the width of the metal blade is maximum in the front area of the board, i.e. approximately the width thereof, is minimum in the central zone or skate zone, i.e. less than the width of the board, and increases in the area back of the board.

Dans le cas d'un ski réalisé suivant cette possibilité, celui-ci possède une bonne raideur à la torsion dans sa zone avant ainsi que dans sa zone arrière, ce qui lui donne un comportement de ski plus spécialement adapté au slalom géant où il s'agit de disposer d'une bonne précision de guidage à l'aide d'une bonne raideur en torsion de la zone avant du ski et d'éviter le dérapage en sortie de virage grâce à une bonne raideur en torsion de l'arrière du ski.In the case of a ski produced according to this possibility, it has good torsional stiffness in its front area as well as in its rear area, which gives it a ski behavior more specifically suitable for giant slalom where it is a question of having a good precision of guidance using a good torsional stiffness of the front area of the ski and avoid skidding out of corners thanks to good stiffness in torsion of the back of the ski.

Suivant une autre forme d'exécution de cette planche, la largeur de la lame métallique est maximale dans la zone avant de la planche et diminue jusque dans la zone arrière de la planche. Dans ce cas, pour la réalisation d'un ski, ce ski est plus confortable à skier que le ski défini précédemment, dans la mesure où la raideur en torsion de la zone arrière étant moindre, ce ski a tendance à déraper en sortie de virage.According to another embodiment of this board, the width of the metal blade is maximum in the front area of the board and decreases to the rear area of the board. In this case, for the making a ski, this ski is more comfortable to ski than the defined ski previously, since the torsional stiffness of the rear region being less, this ski tends to slip at the end of a turn.

La couche de fibres imprégnées de résine peut être située au-dessus ou au-dessous de la lame métallique. Toutefois, elle est avantageusement située au-dessus, afin de pouvoir parfaitement suivre le profil de la face supérieure du ski.The layer of resin-impregnated fibers may be located above or below the metal blade. However, she is advantageously located above, in order to be able to perfectly follow the profile of the upper face of the ski.

Suivant une possibilité, la couche de fibres imprégnées de résine et la lame métallique sont au contact l'une de l'autre. According to one possibility, the layer of fibers impregnated with resin and the metal blade are in contact with each other.

Suivant une forme d'exécution de cette planche, dans au moins une zone de la planche dans laquelle la lame métallique possède une largeur inférieure à celle de la couche de fibres imprégnées de résine, la couche de fibres comporte, au moins de l'un des côtés de la lame métallique, un retour s'étendant sensiblement dans le plan de la lame métallique.According to an embodiment of this plate, in at least an area of the board in which the metal blade has a width lower than that of the resin-impregnated fiber layer, the fibers comprises, at least on one of the sides of the metal blade, a back extending substantially in the plane of the metal blade.

Il est intéressant de réduire la largeur de la lame métallique dans la zone centrale du ski. En effet, cette zone centrale qui reçoit la butée avant et la talonnière arrière pour la fixation d'une chaussure, ou qui reçoit une plateforme pour le montage de la fixation d'une chaussure, d'une part, est rigidifiée par cet ensemble fixation-chaussure et, d'autre part, est soumise à des contraintes très importantes, notamment à ses extrémités de raccordement respectivement avec les zones avant et arrière du ski. Il peut en résulter, si la lame métallique joue un rôle prépondérant dans le renfort supérieur, des déformations définitives de cette lame métallique, correspondant à une destruction du ski. Il est donc intéressant de pouvoir limiter l'importance de la lame métallique dans cette zone centrale du ski, et de privilégier un renfort à l'aide de la couche de fibres imprégnées de résine, dans la mesure où celle-ci possède une capacité de déformation à la flexion réversible beaucoup plus importante que la lame métallique.It is interesting to reduce the width of the metal blade in the central ski area. Indeed, this central area which receives the stop front and rear heel for fixing a shoe, or receiving a platform for mounting the binding of a shoe, on the one hand, is stiffened by this binding-shoe assembly and, on the other hand, is subject to very significant constraints, in particular at its ends of connection respectively with the front and rear areas of the ski. he can result, if the metal blade plays a predominant role in the reinforcement upper, definitive deformations of this metal blade, corresponding to a destruction of the ski. So it's interesting to be able to limit the importance of the metal blade in this central area of the ski, and favor reinforcement using the layer of fibers impregnated with resin, insofar as it has a deformation capacity at the Reversible bending much greater than the metal blade.

La planche selon l'invention peut être une planche possédant une section sensiblement rectangulaire sur toute sa longueur, qu'il s'agisse d'une planche comportant deux parois latérales distinctes de la paroi supérieure, ou d'une planche de type à coque, dans laquelle les parois latérales sont constituées par les prolongements de la paroi supérieure, ou encore d'une planche dans laquelle la paroi supérieure comporte des prolongements formant pour partie les parois latérales, dans la mesure où ces prolongements viennent prendre appui sur au moins une partie de la longueur de la planche sur des éléments de renforcement reposant sur l'ensemble inférieur, et notamment sur les carres.The board according to the invention can be a board having a substantially rectangular section over its entire length, whether a board with two side walls separate from the wall upper, or a hull type board, in which the walls lateral are formed by the extensions of the upper wall, or another board in which the upper wall has extensions partly forming the side walls, insofar as these extensions come to bear on at least part of the length of the board on reinforcing elements resting on the lower assembly, and in particular on the edges.

Suivant une forme d'exécution de cette planche, celle-ci comporte dans ses zones avant et arrière une section générale rectangulaire, tandis que sa face supérieure présente, dans sa zone centrale ou zone de patin, deux nervures longitudinales disposées du côté des deux bords de la planche, raccordées par une partie centrale plus basse, la couche de fibres imprégnées de résine suivant sensiblement, d'un bord à l'autre de la planche, le profil de la face supérieure, et la lame métallique ayant une largeur correspondant à celle de la partie centrale de la face supérieure et étant disposée en-dessous de cette partie centrale.According to an embodiment of this board, this one has a general section in its front and rear areas rectangular, while its upper face has, in its central area or skate area, two longitudinal ribs arranged on the side of the two edges of the board, connected by a lower central part, the layer of fibers impregnated with resin along substantially, from edge to edge the other of the board, the profile of the upper face, and the metal blade having a width corresponding to that of the central part of the face upper and being arranged below this central part.

Il est intéressant de noter que, dans cette forme d'exécution, la largeur développée de la paroi externe de la partie supérieure de la planche, c'est-à-dire la largeur développée de la couche de fibres imprégnées de résine, est augmentée du fait de la présence des deux nervures longitudinales. Il en résulte une augmentation de la quantité de fibres de la couche de renfort fibreux, par rapport au cas où le dessus de la planche serait plat. En outre, la couche de fibres suivant sensiblement la face supérieure de la planche, s'éloigne de la fibre neutre de la planche dans la zone des nervures, ce qui assure une augmentation de la résistance à la flexion et à la torsion. En outre, la forme de tuile que possède la couche de fibres dans la zone de chaque nervure, améliore sa rigidité dans cette zone.It is interesting to note that, in this embodiment, the developed width of the outer wall of the upper part of the board, that is to say the developed width of the layer of fibers impregnated with resin, is increased due to the presence of the two ribs longitudinal. This results in an increase in the amount of fiber in the fibrous reinforcement layer, compared to the case where the top of the board would be flat. In addition, the layer of fibers substantially following the face top of the board, moves away from the neutral fiber of the board in the rib area, which provides increased resistance to bending and twisting. In addition, the form of tile that the layer of fibers in the area of each rib, improves its rigidity in this area.

Suivant une autre forme d'exécution, cette planche comporte une nervure centrale s'étendant sur une grande partie de sa longueur, et de largeur décroissante de la spatule au talon, la couche de fibres imprégnées de résine suivant sensiblement, d'un bord à l'autre de la planche, le profil de la face supérieure et la lame métallique ayant une largeur égale à celle du fond de la nervure et étant disposée en regard de ce fond.According to another embodiment, this board comprises a central rib extending over a large part of its length, and decreasing width from the tip to the heel, the layer of impregnated fibers resin substantially following, from one edge to the other of the board, the profile of the upper face and the metal blade having a width equal to that from the bottom of the rib and being arranged opposite this bottom.

Dans ce cas encore, on trouve une augmentation de la quantité de fibres compte tenu d'une augmentation de la largeur développée de la couche de fibres, qui suit la nervure centrale, un éloignement de la fibre par rapport à la fibre neutre, et une rigidification de la couche de fibres par effet de tuile au niveau de la nervure. En ce qui concerne la lame métallique, il faut noter que, dans la mesure où elle suit la nervure, elle s'éloigne également de la fibre neutre dans la zone centrale de la planche, ce qui augmente notamment sa résistance à la flexion.In this case again, we find an increase in the quantity of fibers due to an increase in the developed width of the layer of fibers, which follows the central rib, a distancing of the fiber by compared to the neutral fiber, and a stiffening of the fiber layer by tile effect on the rib. Regarding the blade metallic, it should be noted that, insofar as it follows the rib, it also moves away from the neutral fiber in the central area of the board, which in particular increases its resistance to bending.

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 d'un ski selon l'invention :

  • Figure 1 est une vue en perspective d'un premier ski comportant deux nervures longitudinales dans sa zone centrale ;
  • Figure 2 est une vue de dessus de ce ski ;
  • Figures 3 à 5 en sont trois vues en coupe transversale dans ses zones arrière, centrale et avant respectivement, les coupes étant réalisées suivant les lignes III-III, IV-IV et V-V de figure 2 ;
  • Figures 6 à 10 sont cinq vues d'un second ski correspondant respectivement aux figures 1 à 5 ;
  • Figures 11 à 13 sont trois vues en coupe transversale dans la zone avant, dans la zone centrale et dans la zone arrière, d'un ski de section rectangulaire.
    • In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting examples, several embodiments of a ski according to the invention:
  • Figure 1 is a perspective view of a first ski having two longitudinal ribs in its central area;
  • Figure 2 is a top view of this ski;
  • Figures 3 to 5 are three views in cross section in its rear, central and front areas respectively, the sections being made along lines III-III, IV-IV and VV of Figure 2;
  • Figures 6 to 10 are five views of a second ski corresponding respectively to Figures 1 to 5;
  • Figures 11 to 13 are three cross-sectional views in the front zone, in the central zone and in the rear zone, of a ski of rectangular section.

    • Le ski représenté aux figures 1 à 5 comprend un ensemble inférieur constitué par une semelle de glissement 2 bordée longitudinalement par deux arêtes métalliques appelées carres 3. Sur l'ensemble inférieur qui peut éventuellement être équipé d'un renfort, non représenté au dessin, repose un noyau 4. De part et d'autre de ce noyau 4, sont disposées des parois longitudinales 5 qui, dans cette forme d'exécution, ne s'étendent pas sur tout la hauteur du ski. L'ensemble supérieur du ski comprend une paroi supérieure 6 formant la face supérieure et comportant deux retours longitudinaux 7 formant une partie des parois longitudinales et reposant sur les éléments 5. Ce ski comporte, sur toute sa longueur utile ou longueur active, c'est-à-dire entre sa ligne de contact avant et sa ligne de contact arrière avec la neige, un renfort supérieur continu constitué par une lame métallique 8, par exemple à base d'alliage d'aluminium connu sous le nom commercial de Zycral, et une couche 9 de fibres, telles que des fibres de verre, de carbone ou de d'aramide ou un mélange de telles fibres imprégnées de résine.The ski represented in FIGS. 1 to 5 comprises an assembly lower formed by a sliding sole 2 bordered longitudinally by two metal edges called edges 3. On the lower assembly which can optionally be equipped with a reinforcement, not shown in the drawing, a core 4 rests. On either side of this core 4, are arranged longitudinal walls 5 which, in this form of execution, do not extend over the entire height of the ski. All upper of the ski comprises an upper wall 6 forming the face upper and comprising two longitudinal returns 7 forming a part longitudinal walls and resting on the elements 5. This ski comprises, over its entire useful length or active length, i.e. between its line of front contact and its rear contact line with snow, a reinforcement continuous upper formed by a metal blade 8, for example based aluminum alloy known under the trade name of Zycral, and a layer 9 of fibers, such as glass fibers, carbon fibers or aramid or a mixture of such fibers impregnated with resin.

    Dans la forme d'exécution représentée au dessin, la couche fibreuse 9 s'étend sur toute la largeur du ski, d'un élément longitudinal 5 situé d'un côté à l'autre élément longitudinal situé de l'autre côté.In the embodiment shown in the drawing, the layer fibrous 9 extends over the entire width of the ski, from a longitudinal element 5 located from one side to the other longitudinal element located on the other side.

    Ce ski possède, dans ses zones arrière 10 et avant 12, une section sensiblement rectangulaire, avec une surface supérieure sensiblement plane, tandis qu'il présente, dans sa zone centrale 13, deux nervures longitudinales 14 disposées du côté des deux bords du ski, et raccordées par une partie centrale plane plus basse 15.This ski has, in its rear zones 10 and front 12, a substantially rectangular section, with an upper surface substantially flat, while it has, in its central zone 13, two longitudinal ribs 14 disposed on the side of the two edges of the ski, and connected by a lower flat central part 15.

    Il ressort clairement de la figure 4, qui est une vue en coupe transversale dans la zone centrale 13, que la couche fibreuse 9 suit le profil de la face supérieure, et notamment le profil des nervures 14, ce qui augmente la largeur dévéloppée de la couche fibreuse 9 par rapport au cas où le ski serait rectangulaire.It is clear from Figure 4, which is a sectional view transverse in the central zone 13, that the fibrous layer 9 follows the profile of the upper face, and in particular the profile of the ribs 14, which increases the developed width of the fibrous layer 9 compared to the case where the ski would be rectangular.

    En ce qui concerne la lame métallique 8, il est visible aux figures 3 et 5 que cette lame possède, dans la zone arrière 10 et dans la zone avant 12, sensiblement la largeur de la paroi supérieure 6, tandis que dans la zone centrale 13 du ski elle possède une largeur correspondant sensiblement à celle de la partie centrale 15 disposée entre les deux nervures 14.Regarding the metal blade 8, it is visible to Figures 3 and 5 that this blade has, in the rear area 10 and in the front zone 12, substantially the width of the upper wall 6, while in the central zone 13 of the ski it has a corresponding width substantially to that of the central part 15 disposed between the two ribs 14.

    Compte tenu de la largeur relativement importante de la lame 8 dans les zones arrière 10 et avant 12, le ski concerné possède une bonne rigidité à la torsion dans ces deux zones, ce qui en fait un ski possèdant une bonne précision de guidage en début de virage, ainsi qu'un bon accrochage en sortie de virage, ce qui correspond aux caractéristiques d'un ski de slalom géant. En ce qui concerne la partie centrale, elle comporte une lame métallique de largeur réduite, avec augmentation de la quantité de couche fibreuse et éloignement de la couche fibreuse par rapport à la fibre neutre. C'est donc la couche fibreuse qui est privilégiée en tant que renfort dans la zone centrale du ski, ce qui est avantageux, dans la mesure où cette zone centrale répond à des sollicitations importantes, notamment en avant et en arrière de la fixation, la zone de fixation étant rigidifiée par la chaussure et éventuellement une plateforme de montage de la fixation de la chaussure.Given the relatively large width of the blade 8 in the rear 10 and front 12 zones, the ski concerned has good torsional stiffness in these two areas, making it a ski with good guidance accuracy at the start of a turn, as well as good hooking at corner exit, which corresponds to the characteristics of a giant slalom ski. As for the central part, it includes a metal blade of reduced width, with increase in the amount of fibrous layer and distance of the fibrous layer from the fiber neutral. It is therefore the fibrous layer which is preferred as a reinforcement in the central area of the ski, which is advantageous, insofar as this central area responds to significant stresses, particularly in before and behind the attachment, the attachment area being stiffened by the shoe and possibly a mounting platform for fixing the shoe.

    Les figures 6 à 10 présentent un autre ski, dans lequel les mêmes éléments sont désignés par les mêmes références que précédemment.Figures 6 to 10 show another ski, in which the same elements are designated by the same references as previously.

    Ce ski présente, sur une grande partie de sa longueur, une nervure centrale 16 de largeur décroissante de l'avant vers l'arrière, la surface supérieure de la nervure ayant à l'avant 12 une largeur L1 supérieure à la largeur L2 au niveau du patin 13, elle-même supérieure à la largeur L3 à l'arrière 10 du ski, comme montré aux figures 8 à 10. La couche fibreuse 9 épouse la forme de la nervure centrale, comme montré aux figures 8 et 9, tandis que la lame métallique 8 possède une largeur correspondant sensiblement à celle du fond de la rainure.This ski has, over a large part of its length, a central rib 16 of decreasing width from front to rear, the upper surface of the rib having at the front 12 a width L 1 greater than the width L 2 at the pad 13, itself greater than the width L 3 at the rear 10 of the ski, as shown in Figures 8 to 10. The fibrous layer 9 follows the shape of the central rib, as shown in Figures 8 and 9 , while the metal blade 8 has a width corresponding substantially to that of the bottom of the groove.

    Dans le cas de ce ski, la largeur de la lame 8 est décroissante de l'avant du ski jusqu'au talon de celui-ci. Comme dans le cas du ski précédent, la forme de la couche fibreuse, sa largeur et son positionnement par rapport à la fibre neutre influent sur le comportement du ski. En outre, dans le cas de ce ski, la largeur de la lame métallique étant inférieure dans la zone arrière 10, ce ski est un ski beaucoup plus confortable que le ski décrit en référence aux figures 1 à 5, puisque, s'il bénéficie d'une bonne rigidité en torsion à son extrémité avant, assurant un bon guidage en début de virage, sa rigidité en torsion est moindre dans sa zone arrière, permettant plus facilement de déraper.In the case of this ski, the width of the blade 8 decreases by the front of the ski to the heel. As in the case of skiing previous, the shape of the fibrous layer, its width and its positioning compared to the neutral fiber influence the behavior of the ski. In addition, in the case of this ski, the width of the metal blade being less in the rear zone 10, this ski is a much more comfortable ski than the ski described with reference to Figures 1 to 5, since, if it has good torsional rigidity at its front end, ensuring good guidance at the start cornering, its torsional rigidity is lower in its rear area, making it easier to slip.

    Les figures 11 à 13 sont trois vues en coupe respectivement dans la zone avant, dans la zone centrale et dans la zone arrière d'un ski de section rectangulaire. Dans ce cas, le ski comporte des éléments longitudinaux 17, sur lesquels repose une paroi supérieure distincte 18. Les figures 11 à 13 montrent une forme d'exécution de ce ski, dans laquelle la couche fibreuse 9 s'étend sur toute la largeur du noyau, tandis que la lame métallique 8 possède une largeur qui décroít depuis l'avant du ski jusqu'à l'arrière de celui-ci comme montré aux figures 11 à 13.Figures 11 to 13 are three sectional views respectively in the front zone, in the central zone and in the rear zone of a ski rectangular section. In this case, the ski has elements longitudinal 17, on which rests a separate upper wall 18. The Figures 11 to 13 show an embodiment of this ski, in which the fibrous layer 9 extends over the entire width of the core, while the blade metal 8 has a width which decreases from the front of the ski to the back of it as shown in Figures 11 to 13.

    Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant une planche de glisse sur neige, dont les caractéristiques de comportement peuvent être modifiées en faisant varier les paramètres relatifs des deux composants, respectivement une lame métallique et une couche fibreuse, constitutifs du renfort supérieur du ski.As is apparent from the above, the invention provides a great improvement to the existing technique by providing a board of slides on snow, the behavioral characteristics of which can be modified by varying the relative parameters of the two components, respectively a metal blade and a fibrous layer, constituting the upper reinforcement of the ski.

    Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de cette planche de glisse sous forme de ski, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que les différentes caractéristiques de variation des proportions, quantités, positionnements par rapport à la fibre neutre et formes des composants, décrits ci-dessus pourraient être combinés de façons différentes sans que l'on sorte pour autant du cadre de l'invention.It goes without saying that the invention is not limited only to embodiments of this board for skiing, described above as examples, on the contrary it embraces all variants. This is how the different characteristics of variation in proportions, quantities, positioning relative to the fiber neutral and component shapes, described above could be combined in different ways without leaving the framework of the invention.
