The peripheral zone extends from the board edge (9) in the direction of the end central zone and has a thickness less than that of the end central zone and is connected to it by a recess (7) forming a rupture point. The width of the peripheral zone, measured perpendicularly to the board edge increases from the start of the end to the highest point of the end.

Description

Domaine TechniqueTechnical area

L'invention se rattache au domaine des planches de glisse sur neige et concerne une structure de planche tel qu'un ski alpin, un surf des neiges, voire encore un ski de fond.The invention relates to the field of sliding boards on snow and relates to a board structure such as an alpine ski, a snowboard or even a cross-country ski.

Elle vise plus particulièrement une structure de spatule ou de talon limitant les risques de fissuration, notamment suite à des chocs à froid.It is more particularly a spatula or heel structure limiting the risk of cracking, especially following cold shocks.

Techniques antérieuresPrevious techniques

De façon générale, la spatule d'un ski alpin, de randonnée, de fond, ou même d'un surf, est relevée pour permettre au ski de surmonter les obstacles de la piste. Ainsi, lorsque le ski rencontre un obstacle, la spatule a tendance à se déformer, et est donc le siège de contraintes mécaniques qui peuvent être importantes. De même, lorsque le ski est à plat, la spatule forme une zone surélevée qui peut subir de nombreux chocs, voire même se déformer, par exemple dans les files d'attente des remontées mécaniques. Les contraintes mécaniques, lorsque la spatule est écrasée par un effort vertical, sont alors très importantes.In general, the spatula of an alpine ski, hiking, bottom, or even a surf, is raised to allow the ski to overcome the obstacles of the track. Thus, when the ski encounters an obstacle, the spatula tends to deform, and is therefore the seat of mechanical stresses that can be important. Similarly, when the ski is flat, the spatula forms an elevated area that can suffer many shocks, or even deform, for example in the queues lifts. The mechanical stresses, when the spatula is crushed by a vertical force, are then very important.

Or, on sait que de façon générale, les skis présentent une structure comportant un empilement de différentes couches superposées. Dans la spatule, ces différentes couches superposées se rejoignent ou s'arrêtent pour former une structure complexe. C'est en spatule que s'arrêtent les carres latérales, ainsi que généralement le noyau du ski et les renforts supérieurs et inférieurs situés de part et d'autre du noyau. Il en résulte des discontinuités de la structure de la spatule à ces différents niveaux, ce qui fragilise la couche formant la face supérieure du ski, également appelée "couche supérieure de protection", lorsque la spatule subit de fortes contraintes mécaniques, et par exemple lorsque la spatule est écrasée ou se déforme en skiant.However, it is known that in general, the skis have a structure comprising a stack of different superimposed layers. In the spatula, these different layers overlap or stop to form a complex structure. It is in spatula that stops the side edges, as well as generally the ski core and the upper and lower reinforcements located on both sides of the core. This results in discontinuities in the structure of the spatula at these different levels, which weakens the layer forming the upper face of the ski, also called "upper protective layer", when the spatula undergoes high mechanical stresses, and for example when the spatula is crushed or deformed while skiing.

On observe alors des fissurations de cette couche supérieure de protection, et ce d'autant plus que la température extérieure est basse, et donc que la matière de la couche supérieure de protection devient rigide. Ces phénomènes apparaissent lorsque la spatule est heurtée par un obstacle ou un autre ski, ou bien encore lorsque le ski frappe la neige, provoquant un mouvement de fouettement de la spatule. On a remarqué que ces fissurations apparaissaient généralement à proximité de l'extrémité de la carre métallique bordant la semelle de glisse. En effet, l'interface entre la carre métallique et le reste de la structure de l'avant de la spatule, constitue un point de faiblesse où les contraintes mécaniques se concentrent, engendrant donc des risques importants de fissuration de la couche supérieure de protection. On a également observé que ces fissures prennent naissance sur les bords latéraux de la spatule, puis se propagent transversalement à toute la largeur de la couche supérieure de protection.Cracks in this upper protective layer are then observed, all the more so since the external temperature is low, and therefore the material of the upper protective layer becomes rigid. These phenomena appear when the spatula is struck by an obstacle or another ski, or even when the ski hits the snow, causing a whip movement of the spatula. It has been noted that these cracks generally appear near the end of the metal edge bordering the gliding sole. Indeed, the interface between the metal edge and the rest of the structure of the front of the spatula, is a point of weakness where the mechanical stresses are concentrated, thus generating significant risks of cracking of the upper protective layer. It has also been observed that these cracks originate on the lateral edges of the spatula and then propagate transversely across the width of the upper protective layer.

Un problème que se propose donc de résoudre l'invention est celui de l'apparition des fissurations sur la couche supérieure de protection au niveau de la spatule d'un ski. Le même problème se pose bien évidemment pour d'autres planches de glisse, tel que les skis de fond, les skis de randonnée, ou bien encore un surf des neiges. Ce problème est également observé, bien qu'à un degré moindre, sur les extrémités arrière de skis, qui sont également légèrement relevées.A problem that the invention proposes to solve is that of the appearance of cracks on the upper protective layer at the level of the spatula of a ski. The same problem obviously arises for other boards, such as cross-country skis, ski touring, or snowboarding. This problem is also observed, albeit to a lesser degree, on the back ends of skis, which are also slightly raised.

Ce problème est également observé sur des planches de surf, et notamment celles décrites dans le document FR 2 804 335 . Ces planches sont conçues dans un but de réduire la résistance à la flexion des extrémités qui sont légèrement relevées. Pour ce faire, le noyau de la planche est d'épaisseur constante, mais il présente une largeur évolutive, qui diminue en se dirigeant vers les extrémités de la planche. Au niveau de la naissance de la spatule, la structure de la planche est donc affaiblie, car elle est relativement peu épaisse sur une assez forte largeur.This problem is also observed on surfboards, and in particular those described in the document FR 2 804 335 . These boards are designed to reduce the bending resistance of the slightly raised ends. To do this, the core of the board is of constant thickness, but it has a scalable width, which decreases towards the ends of the board. At the birth of the spatula, the structure of the board is weakened because it is relatively thin on a fairly large width.

Exposé de l'inventionPresentation of the invention

L'invention concerne donc une planche de glisse, comportant une semelle de glisse se terminant par au moins une extrémité relevée, à savoir du côté avant de la spatule et/ou du côté arrière du talon.The invention therefore relates to a gliding board, comprising a gliding soleplate ending with at least one raised end, namely the front side of the spatula and / or the rear side of the heel.

L'extrémité de cette planche comporte une zone périphérique et une zone centrale, la zone périphérique s'étendant depuis le bord de la planche en direction de la zone centrale de l'extrémité. Cette zone périphérique présente une épaisseur inférieure à celle de la zone centrale de l'extrémité, et se raccorde à cette dernière par un décrochement formant une rupture de pente.The end of this board has a peripheral zone and a central zone, the peripheral zone extending from the edge of the plank towards the central zone of the end. This peripheral zone has a thickness less than that of the central zone of the end, and connects to the latter by a recess forming a slope break.

Conformément à l'invention, la largeur de la zone périphérique caractéristique, mesurée perpendiculairement au bord de la planche, est croissante depuis la naissance de l'extrémité relevée, jusqu'au point le plus haut de cette extrémité.According to the invention, the width of the characteristic peripheral zone, measured perpendicularly to the edge of the board, increases from the birth of the raised end to the highest point of this end.

Autrement dit, l'épaisseur de la spatule est fortement réduite à proximité du bord de la planche, ce qui fait que la couche supérieure de protection de la planche subit des contraintes moins importantes lorsque la spatule se déforme, de sorte que les risques de fissuration de la couche supérieure de protection sont fortement diminués. La rigidité globale de la spatule reste assurée par la partie centrale de cette dernière qui présente une épaisseur suffisante, correspondant sensiblement à celle du reste de l'avant de la planche, au niveau de la naissance de la spatule. Le décrochement, séparant la zone centrale de la spatule de la zone périphérique de moindre épaisseur, s'écarte progressivement du bord de la planche pour former un arc dont la forme s'apparente à celle du bord de la spatule, mais est décalé à l'intérieur de cette dernière. A l'effet technique de réduction du risque de fissuration, se rajoute alors un effet d'aspect de la spatule ainsi conformée.In other words, the thickness of the spatula is greatly reduced near the edge of the board, so that the upper protective layer of the board undergoes less stress when the spatula deforms, so that the risk of cracking of the upper layer of protection are greatly diminished. The overall rigidity of the spatula remains ensured by the central part of the latter which has a sufficient thickness, corresponding substantially to that of the rest of the front of the board, at the birth of the spatula. The recess, separating the central zone of the spatula from the smaller peripheral zone, progressively diverges from the edge of the board to form an arc whose shape is similar to that of the edge of the spatula, but is shifted to the inside of the latter. To the technical effect of reducing the risk of cracking, then adds an appearance effect of the spatula and conformed.

En pratique, la face supérieure de la zone périphérique caractéristique peut être soit sensiblement parallèle à la face inférieure de la planche, soit encore légèrement inclinée vers le bas et en direction du bord de la planche.In practice, the upper face of the characteristic peripheral zone may be either substantially parallel to the lower face of the board, or still slightly inclined downwards and towards the edge of the board.

En pratique, la zone périphérique caractéristique est préférentiellement symétrique par rapport au plan longitudinal médian de la planche.In practice, the characteristic peripheral zone is preferably symmetrical with respect to the median longitudinal plane of the board.

En pratique, on a observé que les risques de fissuration de la couche supérieure de protection étaient fortement réduits lorsque la largeur de la zone périphérique, mesurée au niveau de l'interruption de la carre métallique, était supérieure à 5 mm dans le cas d'un ski alpin, ou 10 mm dans le cas d'un surf des neiges plus large.In practice, it has been observed that the risks of cracking of the upper protective layer are greatly reduced when the width of the peripheral zone, measured at the edge of the metal edge, was greater than 5 mm in the case of downhill skiing, or 10 mm in the case of a wider snowboard.

  • les figures 4 et 5 sont des vues en coupe respectivement sur les plans IV-IV' et V-V' de la figure 3.
The manner of carrying out the invention, as well as the advantages which result therefrom, will emerge from the description of the embodiments which follow, in support of the appended figures in which:
  • the figure 1 is a summary perspective view of the spatula of a ski according to the invention;
  • the figure 2 is a side view of the ski from the figure 1 ;
  • the figure 3 is a top view of the front end of the ski from the figure 1 ;
  • the Figures 4 and 5 are sectional views respectively on planes IV-IV 'and VV' of the figure 3 .

Manière de réaliser l'inventionWay of realizing the invention

Comme déjà évoqué, l'invention concerne une planche de glisse qui, dans l'exemple illustré aux figures, est un ski alpin. Mais l'invention peut de la même manière s'appliquer à tout autre type de ski, tels que les skis de randonnée, les skis courts ou patinettes, ou bien encore les skis de fond. De la même manière, un surf peut également être construit selon les principes de l'invention.As already mentioned, the invention relates to a gliding board which, in the example illustrated in the figures, is an alpine ski. But the invention can similarly apply to any other type of ski, such as ski touring, short skis or skates, or even cross-country skis. In the same way, a surf can also be constructed according to the principles of the invention.

Ainsi, comme illustré à la figure 1, un ski (1) comporte une extrémité avant relevée (2) formant la spatule. De façon générale, le ski (1) présente sur ses arêtes inférieures des carres (3) bordant la semelle de glisse (4). Conformément à l'invention, la spatule (2) présente une zone périphérique (5), bordant une zone centrale (6), et séparée de cette dernière par un décrochement (7).Thus, as illustrated in figure 1 , a ski (1) has a raised front end (2) forming the spatula. In general, the ski (1) has on its lower edges edges (3) bordering the gliding sole (4). According to the invention, the spatula (2) has a peripheral zone (5), bordering a central zone (6), and separated from the latter by a recess (7).

Ce décrochement (7) est tel que l'épaisseur (e1) de la spatule (2) dans la zone centrale (6) est nettement supérieure à l'épaisseur (e2) de la spatule au niveau de la zone périphérique (5). Par un décrochement, on entend qu'il y a une différence sensible d'épaisseur, de l'ordre de 2 mm.This recess (7) is such that the thickness (e1) of the spatula (2) in the central zone (6) is significantly greater than the thickness (e2) of the spatula at the peripheral zone (5). By a recess, it is meant that there is a substantial difference in thickness, of the order of 2 mm.

L'épaisseur (e2) de la zone périphérique (5) peut être soit sensiblement constante sur toute la périphérie de la spatule (2), mais elle peut également présenter certaines variations. Cette épaisseur (e2) peut également être constante à un même niveau longitudinal de la planche, de sorte que la face supérieure de la zone périphérique (5) est alors parallèle à la semelle (4) de la planche.The thickness (e2) of the peripheral zone (5) may be substantially constant over the entire periphery of the spatula (2), but it may also have certain variations. This thickness (e2) can also be constant at the same level longitudinal of the board, so that the upper face of the peripheral zone (5) is then parallel to the sole (4) of the board.

Dans d'autres variantes, l'épaisseur (e2) de la zone périphérique (5) peut être légèrement variable, et par exemple décroissante en se rapprochant du bord (9) de la planche. Dans ce cas, la face supérieure de la zone périphérique est alors légèrement inclinée vers le bas et l'extérieur. De multiples variantes peuvent être imaginées en combinant ces différentes dispositions, sans sortir du cadre de l'invention.In other variants, the thickness (e2) of the peripheral zone (5) may be slightly variable, and for example decreasing when approaching the edge (9) of the board. In this case, the upper face of the peripheral zone is then slightly inclined downwards and outwards. Multiple variants can be imagined by combining these different provisions, without departing from the scope of the invention.

Comme illustré à la figure 3, la largeur (d) de la zone périphérique (7) est variable sur le pourtour de la spatule (2). Ainsi, cette largeur (d), mesurée perpendiculairement au bord (9) de la spatule, entre ce dernier et le décrochement (7), part d'une valeur sensiblement nulle au niveau de la naissance (11) de la zone périphérique, pour atteindre une valeur maximum au sommet (12) de la spatule. La largeur (d) mesurée au niveau de l'extrémité (13) de la carre latérale (5), est typiquement supérieure à 5 mm, pour obtenir une limitation suffisante des risques de fissuration de la couche supérieure de protection (15) illustrée à la figure 4.As illustrated in figure 3 , the width (d) of the peripheral zone (7) is variable around the periphery of the spatula (2). Thus, this width (d), measured perpendicularly to the edge (9) of the spatula, between the latter and the recess (7), starts from a substantially zero value at the birth level (11) of the peripheral zone, for reach a maximum value at the top (12) of the spatula. The width (d) measured at the end (13) of the lateral edge (5) is typically greater than 5 mm, to obtain a sufficient limitation of the risks of cracking of the upper protective layer (15) illustrated in FIG. the figure 4 .

Ainsi, comme illustré aux figures 4 et 5, la couche supérieure de protection (15) est plus proche de la semelle (4) de la planche au niveau de la zone périphérique (5) qu'elle ne l'est au niveau de la zone centrale (6) de la spatule. La structure interne de la planche, entre la couche supérieure de protection (15) et la semelle (4), a volontairement été omise dans les figures 4 et 5, puisqu'elle peut adopter de multiples architectures, selon que le noyau est réalisé soit à base de pièces préalablement mises en forme, ou bien encore est réalisé directement par injection in-situ de composants s'expansant lors du moulage. Le décrochement caractéristique peut résulter d'un décrochement formé dans le noyau. De multiples renforts métalliques fibreux ou autres peuvent être employés sans sortir du cadre de l'invention.Thus, as illustrated in Figures 4 and 5 , the upper protective layer (15) is closer to the sole (4) of the board at the peripheral zone (5) than it is at the central region (6) of the spatula. The internal structure of the board, between the upper layer of protection (15) and the sole (4), was deliberately omitted in the Figures 4 and 5 since it can adopt multiple architectures, depending on whether the core is made from previously shaped parts, or is made directly by in-situ injection of components expanding during molding. The characteristic recess may result from a recess formed in the core. Multiple fibrous metal reinforcements or others may be employed without departing from the scope of the invention.

Bien entendu, la conception de la spatule illustrée aux figures peut se transposer à la zone arrière d'un ski, pour former le relevé de talon, ou bien encore à d'autres types de planches, notamment aux surfs des neiges, en adaptant les dimensions à ce type de planche.Of course, the design of the spatula illustrated in the figures can be transposed to the rear area of a ski, to form the heel survey, or even to other types of boards, including snowboards, adapting the dimensions to this type of board.

Il ressort de ce qui précède que la conception de la spatule, ou plus généralement de l'extrémité de la planche conforme à l'invention, permet de limiter très fortement les risques de fissuration de la couche supérieure de protection, et de manière plus générale, de la structure de la planche, lorsque la spatule subit des déformations importantes, notamment lors des chocs.It follows from the foregoing that the design of the spatula, or more generally of the end of the board according to the invention, makes it possible to very greatly limit the risks of cracking of the upper protective layer, and more generally of the structure of the board, when the spatula undergoes significant deformations, especially during shocks.
