Abstract

The ski consists of an elongated body having a sole (6) with edges (7, 8), lower and upper reinforcing layers (9, 16) and a core (12). The core has a hard central section (18), e.g. of wood, that extends for part of the width and length of the ski, and edging (22) of a softer material along the sides, front and rear of the central section, which projects 1.5 - 8 mm above the edging.

Description

L'invention concerne un ski prévu pour la pratique du ski alpin.The invention relates to a ski intended for skiing alpine.

De façon connue, un ski se présente comme une poutre allongée ayant à sa face inférieure une semelle de glisse, et recevant à sa face supérieure des éléments de retenue prévus pour retenir la chaussure du skieur.In a known manner, a ski is presented like a beam elongated with a gliding sole on its underside, and receiving on its upper face provided retaining elements to hold the skier's shoe.

La répartition de pression du ski sur sa surface de glisse est un paramètre important qui détermine les qualités de glisse du ski et de conduite en virage.The pressure distribution of the ski on its sliding surface is an important parameter that determines the qualities of skiing and cornering.

On a proposé de nombreuses solutions visant à mieux maítriser cette répartition de pression.Many solutions have been proposed to better control this pressure distribution.

Parmi ces solutions, celle décrite dans la demande de brevet EP 938 917 propose de monter les éléments de retenue sur deux platines oscillantes reliées au ski par des axes d'articulation transversaux qui traversent la structure du ski. Les platines sont reliées entre elles par une liaison.Among these solutions, that described in the application for EP 938 917 proposes to mount the retaining elements on two oscillating plates connected to the ski by axes transverse joints that cross the structure of the ski. The plates are linked together by a link.

Une telle construction donne de bons résultats. Toutefois, il est plutôt adapté à des skis qui sont relativement étroits au niveau du patin, c'est-à-dire la partie centrale du ski.Such a construction gives good results. However, it is more suitable for skis that are relatively narrow at the level of the skate, that is to say the central part of the ski.

Un but de l'invention est de proposer une construction de même type qui convienne mieux pour des skis larges.An object of the invention is to propose a construction of same type which is better suited for wide skis.

Le ski selon l'invention comprend un corps allongé, des extrémités avant et arrière, une semelle de glisse surmontée d'au moins une couche de renfort inférieure, d'un noyau et d'au moins une couche de renfort supérieure. Il est caractérisé par le fait que le noyau a une âme centrale en matériau dur qui s'étend sur une partie de la longueur et de la largeur du ski, et une bordure en matériau plus tendre qui borde l'âme sur les côtés, l'avant et l'arrière.The ski according to the invention comprises an elongated body, front and rear ends, a gliding sole topped at least one lower reinforcing layer, a core and at least one upper reinforcing layer. It is characterized in that the core has a central core in hard material that spans part of the length and the width of the ski, and a border of softer material which borders the soul on the sides, front and back.

Selon une caractéristique secondaire, l'âme centrale est en saillie dans le sens de la hauteur par rapport au reste du noyau.According to a secondary characteristic, the central core is projecting vertically from the rest of the core.

Selon une autre caractéristique secondaire, le ski est surmonté de deux platines oscillantes ayant une surface supérieure de montage prévue pour recevoir des éléments de retenue, les platines étant assemblées au ski autour d'un axe transversal porté par l'âme du noyau. According to another secondary characteristic, skiing is surmounted by two oscillating plates having a surface mounting upper intended to receive elements of retained, the plates being assembled to the ski around an axis transverse carried by the core core.

L'invention sera mieux comprise en se référant à la description ci-dessous et aux dessins en annexe qui lui sont attachés.The invention will be better understood by referring to the description below and attached drawings attached to it attached.

La figure 1 représente en perspective un ski nu selon la présente invention.Figure 1 shows in perspective a bare ski according to the present invention.

La figure 2 est une vue en coupe du ski de la figure 1 au niveau de sa zone centrale.Figure 2 is a sectional view of the ski of Figure 1 to level of its central area.

La figure 3 est une vue en coupe du ski de la figure 1 vers l'une de ses extrémités.Figure 3 is a sectional view of the ski of Figure 1 towards one of its ends.

La figure 4 montre l'âme du noyau.Figure 4 shows the core core.

La figure 5 montre la zone centrale du ski de la figure 1 équipée de platines.Figure 5 shows the central area of the ski in Figure 1 fitted with plates.

La figure 6 est une vue en coupe transversale du ski au niveau de l'une des platines.Figure 6 is a cross-sectional view of the ski at level of one of the plates.

Le ski 1 qui est représenté en figure 1 comprend un corps allongé 2, avec deux extrémités avant et arrière 3 et 4. L'extrémité avant 3 est relevée et arrondie pour former une spatule. Dans le mode de réalisation illustré, l'extrémité arrière 4 est également relevée et arrondie. Ceci toutefois n'est pas limitatif, et l'on pourrait avoir une extrémité coupée droite comme pour un ski traditionnel.The ski 1 which is represented in FIG. 1 comprises a body elongated 2, with two front and rear ends 3 and 4. The front end 3 is raised and rounded to form a spatula. In the illustrated embodiment, the end rear 4 is also raised and rounded. This however is not limiting, and we could have one end cut straight as for a traditional ski.

De façon connue, le ski 1 a dans sa partie inférieure une semelle de glisse 6. La semelle est bordée latéralement par deux carres latérales 7 et 8.In known manner, the ski 1 has in its lower part a gliding sole 6. The sole is bordered laterally by two side edges 7 and 8.

La semelle de glisse 6 est surmontée d'une couche de renfort 9 en résine armée de fibres, elle-même surmontée de préférence par une couche de renfort métallique 10, réalisée notamment en aluminium. Ces différentes couches sont logées entre les carres 7 et 8.The sliding sole 6 is topped with a layer of reinforcement 9 in resin reinforced with fibers, itself topped with preferably by a metallic reinforcing layer 10, produced especially aluminum. These different layers are housed between edges 7 and 8.

Au dessus de ce sous-ensemble inférieur se trouve le noyau 12 qui va être décrit en détail plus loin. Au-dessus du noyau se trouve de préférence une couche 14 de renfort métallique qui est de même nature que la couche 10. Si la couche 10 est présente, en principe la couche 14 l'est également. Enfin une couche de renfort supérieure 16 en résine armée d'une nappe de fibres recouvre l'ensemble à la manière d'une coque, c'est-à-dire que cette couche redescend le long des flancs latéraux jusque sur les carres latérales. De préférence, comme cela est visible dans les figures 3 et 4, les carres débordent de chaque côté sur une petite largeur, et la couche de renfort supérieure 16 descend jusqu'au contact de ces parties débordantes qu'elle recouvre.Above this lower subset is the nucleus 12 which will be described in detail later. Above the nucleus there is preferably a layer 14 of metal reinforcement which is of the same nature as layer 10. If layer 10 is present, in principle the layer 14 is also present. Finally a upper reinforcement layer 16 made of resin reinforced with a layer of fibers covers the whole in the manner of a shell, that is to say as this layer descends along the lateral flanks up to the side edges. Preferably, as is visible in Figures 3 and 4, the edges overflow each side over a small width, and the reinforcing layer upper 16 descends until contact with these parts overflowing that it covers.

De façon classique, un film de collage est interposé entre les couches de renfort métalliques si elles sont présentes et le noyau. Ces couches n'ont pas été représentées dans les figures. En outre, la couche de renfort supérieure est recouverte d'une couche de décoration qui n'est pas non plus représentée dans les figures. Cette couche de décoration est de tout type approprié et connu.Conventionally, a bonding film is interposed between the metallic reinforcing layers if they are present and the core. These layers were not represented in the figures. In addition, the top reinforcement layer is covered with a decorative layer which is also not shown in the figures. This decorative layer is of any suitable and known type.

Selon l'invention, le noyau 12 comprend deux parties principales de nature différente. Tout d'abord, le noyau 12 a une âme centrale 18 réalisée en un matériau relativement dur, tel que du bois. L'âme centrale s'étend sur une portion seulement de la longueur et de la largeur du ski.According to the invention, the core 12 comprises two parts main ones of a different nature. First, the nucleus 12 has a central core 18 made of a relatively hard material, such as wood. The central core extends over a portion only the length and width of the ski.

Selon le mode de réalisation illustré, l'âme centrale repose dans le sens de la hauteur sur le sous-ensemble inférieur, c'est-à-dire sur la couche de renfort 10 métallique. Et elle fait saillie vers le haut par rapport au reste du noyau. Ainsi, dans la figure 1 l'arête en saillie 19 est formée par l'âme centrale du noyau recouverte des couches de renfort supérieures. Dans la partie centrale du ski, l'arête en saillie est relativement large. Sa largeur est proche de celle d'un ski traditionnel soit environ 60 millimètres. Cette valeur n'est pas limitative.According to the illustrated embodiment, the central core rests vertically on the subassembly lower, i.e. on the reinforcement layer 10 metallic. And it protrudes upward from the rest of the nucleus. Thus, in Figure 1 the projecting edge 19 is formed by the central core of the core covered with layers upper reinforcement. In the central part of the ski, the projecting edge is relatively wide. Its width is close to that of a traditional ski, around 60 millimeters. This value is not limitative.

La figure 4 représente en perspective l'âme 18 du noyau. Elle est formée par exemple par un bloc de bois allongé. Le bloc est affiné dans le sens de la largeur vers chacune de ses extrémités 18a et 18b. Dans ces zones, son épaisseur est également réduite par usinage de sa partie supérieure. Dans sa partie médiane 21, l'âme 18 a des bords latéraux et des faces supérieure et inférieure sensiblement parallèles.Figure 4 shows in perspective the core 18 of the core. It is formed for example by an elongated block of wood. The block is narrowed in width towards each of its ends 18a and 18b. In these areas, its thickness is also reduced by machining its upper part. In his middle part 21, the core 18 has lateral edges and faces upper and lower substantially parallel.

Comme cela a été dit précédemment, l'âme est réalisée de préférence en bois, par exemple en lamelles de hêtre et de peuplier collées et il est façonné par usinage.As said before, the soul is made of preferably in wood, for example in beech and poplar glued and it is shaped by machining.

Le reste du noyau qui forme la bordure 22 de l'âme 18 latéralement, sur l'avant et l'arrière est réalisé en un matériau plus tendre et plus léger que l'âme. Par exemple la bordure est en mousse de polyuréthane éventuellement armée de fibres de verre. Cette bordure est par exemple réalisée à partir d'un pain de mousse découpé ou usiné à la forme désirée, avec une découpe centrale dans laquelle est logée l'âme.The rest of the core which forms the border 22 of the core 18 laterally, on the front and rear is made in one softer and lighter material than the core. For example the border is in polyurethane foam possibly reinforced with glass fibers. This border is for example made at from a foam bar cut or machined to shape desired, with a central cut in which is housed blade.

L'âme centrale et la bordure définissent deux zones du ski d'altitude bien distincte. Pour tenir compte de cela, de préférence, la couche de renfort métallique 14, si elle est présente est formée de deux parties, une partie de bordure 14a qui recouvre la bordure du noyau et qui a une découpe centrale traversée par l'âme 18, et une partie centrale 14b qui recouvre la face supérieure de l'âme centrale 18 du noyau en épousant sa forme.The central core and the border define two areas of the ski of very distinct altitude. To account for this, of preferably the metallic reinforcing layer 14, if it is present is formed by two parts, a border part 14a which covers the edge of the core and which has a central cutout crossed by the core 18, and a central part 14b which covers the upper face of the central core 18 of the core in marrying its shape.

La section du ski représentée en figure 2 est réalisée dans la zone centrale, où on a l'âme 18 et la bordure 22 du noyau côte à côte. La section de la figure 3 est réalisée vers l'une ou l'autre des extrémités où le noyau est formé uniquement par la bordure 22.The section of the ski shown in Figure 2 is made in the central area, where we have the core 18 and the border 22 of the core side by side. The section of Figure 3 is made towards either end where the nucleus is formed only by border 22.

On a réalisé un ski selon ce mode de construction ayant les dimensions suivantes, longueur 1950 millimètres, largeur maximale en spatule 120 millimètres, largeur minimale dans la zone centrale 86 millimètres, largeur maximale en talon 115 millimètres, avec un noyau ayant une âme de 1200 millimètres de long, 60 millimètres de large, en saillie de 8 millimètres vers le milieu et 1,5 millimètres vers les extrémités par rapport au reste du noyau, l'épaisseur du ski étant de 12 millimètres dans ces zones de bordure. Naturellement, ces chiffres ne sont donnés qu'à titre d'exemple et n'ont pas de valeur limitative.We made a ski according to this construction method having the following dimensions, length 1950 millimeters, width maximum in spatula 120 millimeters, minimum width in the central zone 86 millimeters, maximum width in heel 115 millimeters, with a core having a core of 1200 millimeters long, 60 millimeters wide, projecting 8 millimeters towards the middle and 1.5 millimeters towards the ends by compared to the rest of the core, the thickness of the ski being 12 millimeters in these border areas. Naturally, these figures are given as an example only and have no limiting value.

Pour supporter les éléments de retenue de la chaussure, le ski de l'invention est équipé de préférence de deux platines 23 et 24. Les platines ont la même construction, avec une face supérieure de montage 23a, 24a qui est prévue pour être percée et recevoir des éléments de retenue avant et arrière d'un type connu. Les faces de montage 23a et 24a sont maintenues légèrement surélevées par rapport à la surface supérieure du ski.To support the shoe retaining elements, the ski of the invention is preferably equipped with two plates 23 and 24. The plates have the same construction, with one side mounting upper 23a, 24a which is intended to be drilled and receive front and rear retainers of a type known. The mounting faces 23a and 24a are maintained slightly raised from the upper surface of the ski.

Les platines chevauchent l'arête 19 du ski. Elles sont formées chacune par exemple par une plaque en aluminium ou autre qui est pliée à la largeur de l'arête 19 de façon à former deux ailes latérales qui redescendent le long des flancs de l'arête 19.The plates overlap the edge 19 of the ski. They are each formed for example by an aluminum plate or other which is folded to the width of the edge 19 so as to form two lateral wings which descend along the sides of the ridge 19.

Ainsi la platine 23 qui est représentée en section dans la figure 6 a deux ailes latérales 23b, 23c qui longent l'arête 19.Thus the plate 23 which is represented in section in the Figure 6 has two side wings 23b, 23c which run along the edge 19.

Chacune des ailes est percée d'un orifice traversé par une vis qui est vissée dans l'âme. Les vis d'assemblage d'une platine sont vissées dans l'alignement l'une de l'autre, de façon à définir pour la platine un axe transversal d'oscillation qui traverse l'âme du noyau. En variante, à la place des vis, on pourrait avoir un goujon ou autre qui traverse la structure du ski. On pourrait aussi utiliser des inserts logés dans la structure du ski lors de sa fabrication.Each of the wings is pierced with an orifice crossed by a screw which is screwed into the core. The assembly screws of a plate are screwed in alignment with each other, so as to define for the plate a transverse axis of oscillation which crosses the core of the nucleus. Alternatively, at the place screws, we could have a stud or something that crosses the structure of the ski. We could also use inserts housed in the ski structure during its manufacture.

Pour permettre le passage des têtes de vis au moment du montage, de préférence, le ski présente dans la zone de bordure de l'arête quatre rainures transversales de faible profondeur 26, 27, 28, 29 en alignement avec les logements des vis. La profondeur des rainures est déterminée pour permettre le passage des têtes de vis. De plus, contre l'arête, le ski a un petit évidement au niveau de chacun des logements de vis, pour permettre le logement de l'aile de la platine. Les évidements 34 et 35 pour les ailes 23b et 23c sont visibles dans la figure 6. Ces différents reliefs du ski sont mis en forme par découpe ou usinage du noyau, ou un autre moyen approprié. De préférence, la couche de renfort métallique 14 est mise en forme pour épouser ces reliefs.To allow the passage of the screw heads when mounting, preferably, the ski present in the area of edge of the ridge four low transverse grooves depth 26, 27, 28, 29 in alignment with the housing of the screw. The depth of the grooves is determined to allow the passage of the screw heads. In addition, against the ridge, the ski has a small recess in each of the screw housings, to allow the housing of the plate wing. The recesses 34 and 35 for the wings 23b and 23c are visible in figure 6. These different reliefs of the ski are set shape by cutting or machining the core, or other means appropriate. Preferably, the metal reinforcing layer 14 is shaped to match these reliefs.

Au-dessus de l'arête 19, des fines plaquettes 30, 31, 32, 33 d'un matériau déformable, par exemple en élastomère, sont intercalées entre les faces de montage des platines et la surface supérieure de l'arête. On peut réaliser les plaquettes avec une dureté différente, dans ce cas, de préférence, les plaquettes intérieures 31 et 32 sont plus dures que les plaquettes extérieures 30 et 33. Les plaquettes comblent l'espace entre les platines et le ski.Above the edge 19, thin plates 30, 31, 32, 33 of a deformable material, for example an elastomer, are inserted between the mounting faces of the plates and the upper surface of the ridge. We can make the plates with a different hardness, in this case, preferably, the inner pads 31 and 32 are harder than outer pads 30 and 33. The pads fill the space between the frames and the ski.

Lors de la glisse, le noyau en deux parties permet un meilleur étalement des pressions. En effet, l'âme en bois raidit la partie centrale du ski où est concentrée la plus grande partie des forces de pression. Elle agit comme une poutre qui étale sur toute sa longueur les efforts d'appui de la chaussure qui sont concentrés au niveau des liaisons entre les platines et du ski. De ce fait, les pics de pression que l'on rencontre usuellement vers chaque liaison ou chaque élément de retenue sont atténués. En outre, les plaques oscillantes qui portent les éléments de retenue de la chaussure libèrent le ski en flexion et assurent un meilleur enroulement du ski dans les courbes, d'où une meilleure conduite du ski. La partie du noyau qui est en mousse confère au ski de la légèreté, et également une certaine souplesse. Il est possible de cette façon de construire des skis très larges, notamment dans la zone centrale. Ces skis ont une grande portance, compte tenu de leur surface de glisse. Ils ont néanmoins une grande maniabilité grâce à la construction particulière du noyau et aux platines articulées.When sliding, the two-part core allows a better pressure spreading. Indeed, the wooden soul stiffens the central part of the ski where most is concentrated large part of the pressure forces. She acts like a beam which spreads over its entire support forces the shoe which are concentrated at the level of the connections between turntables and skiing. As a result, the pressure peaks that one usually meets towards each connection or each retainer are mitigated. In addition, the plates oscillating which carry the retainers of the boots release the ski in flexion and ensure better winding of the ski in the curves, hence better driving the ski. The foam part of the core gives to ski lightness, and also a certain flexibility. he is possible this way to build very skis wide, especially in the central area. These skis have a great lift, given their sliding surface. They nevertheless have great maneuverability thanks to the construction particular to the core and to the articulated plates.

Naturellement la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally this description is given only indicative, and we could adopt other layouts work of the invention without departing from the scope of this one.

En particulier, l'âme du noyau en matériau dur pourrait occuper une partie seulement de l'épaisseur du noyau. Sur l'autre partie de son épaisseur, le noyau serait formé par le même matériau que la bordure, notamment la mousse de polyuréthanne.In particular, the core of the hard material core could occupy only part of the thickness of the core. Sure the other part of its thickness, the core would be formed by the same material as the border, in particular foam polyurethane.

Dans ce cas, l'âme du noyau ne serait pas en contact direct avec le sous-ensemble inférieur du ski, mais garderait néanmoins sa fonction d'étalement de la pression sur la surface de glisse.In this case, the core soul would not be in contact direct with the lower sub-assembly of the ski, but would keep nevertheless its function of spreading the pressure on the sliding surface.

Egalement on pourrait mettre en oeuvre un autre mode de montage des éléments de retenue. Par exemple, les éléments pourraient être assemblés directement sur le dessus de l'arête 19 en profitant de sa grande largeur. Dans ces conditions, on pourrait réduire la différence d'altitude entre le sommet de l'arête et le reste du ski. A la limite, l'âme et la bordure pourraient avoir sensiblement la même épaisseur.We could also implement another mode of mounting of the retaining elements. For example, the elements could be assembled directly on top of the ridge 19 taking advantage of its great width. Under these conditions, we could reduce the altitude difference between the top of the ridge and the rest of the ski. Ultimately, the soul and the border could have substantially the same thickness.
