Description

Ski à rayon court associé à une spatule longue Short radius ski combined with a long tip
L'invention concerne un ski associé à une spatule longue. 11 se rattache au domaine des sports de glisse, et plus précisément des skis alpins. Elle se rapporte plus particulièrement à la famille des skis alpins de taille moyenne, et présentant une ligne de cote horizontale à la mode actuelle creusée.The invention relates to a ski associated with a long tip. It relates to the field of sliding sports, and more precisely of alpine skis. It relates more particularly to the family of medium-sized alpine skis, with a horizontal dimension line in the current hollowed fashion.
Comme on le sait, la tendance actuelle est à l'amélioration de la facilité, c'est-à-dire à la maniabilité et au confort en toute neige notamment par la réduction de la longueur des skis et l'ajout d'extrémités, talon et spatule, plus longues.As we know, the current trend is to improve ease, that is to say maneuverability and comfort in any snow, in particular by reducing the length of skis and adding ends, longer heel and tip.
Ainsi, depuis une dizaine d'années, l'arrivée des skis dit carvés, soit avec une taille très creusée, la longueur moyenne d'un ski a diminué de plus de 20 cmThus, for ten years, the arrival of so-called carved skis, that is to say with a very hollow size, the average length of a ski has decreased by more than 20 cm
On a observé que la largeur des skis, notamment dans la zone spatule et talon, est en constante augmentation pour conserver une surface portante suffisante dans les neiges profondes.It has been observed that the width of the skis, especially in the tip and heel area, is constantly increasing to maintain a sufficient bearing surface in deep snow.
On assiste également à une autre modification concernant les skis alpins, à savoir la tendance à adopter des lignes de cotes de plus en plus creusées. Un inventeur norvégien avait déjà déposé un brevet en 1887 revendiquant cette conception. Cette invention n'avait pas pu être appliquée pour la fabrication des skis en bois de l'époque.We are also witnessing another modification concerning alpine skis, namely the tendency to adopt more and more hollow side lines. A Norwegian inventor had already filed a patent in 1887 claiming this design. This invention could not have been applied to the manufacture of wooden skis of the time.
Les systèmes de fabrication connus actuellement ont permis cette application avec succès près de cent ans après. Cette application aux skis contemporains a permis de fabriquer des skis, dont les virages sont de plus en plus "coupés", c'est-à-dire que les dérapages de l'arrière du ski en sortie de virage sont progressivement di-minués, et très souvent inexistants. Dans ce cas, la conduite du virage s'effectue préférentiellement sur la carre qui procure un gain de précision et de vitesse. Plus précisément, la tendance au creusement de la ligne de cote se mesure par l'augmentation de la différence entre la largeur de la zone spatule et la largeur de la zone patin. Un des problèmes que se propose de résoudre l'invention est celui du manque de polyvalence des skis entre leur comportement sur neiges dures pour les skis du type carving (skis creusés et avec une largeur de 62 à 65 mm au patin) et dans des neiges profondes pour les skis du type freeride (skis creusés avec un rayon de 18 à 30 m, avec une largeur de 68 à 75 mm au patin) ou encore toujours dans les neiges profondes les skis du type dit fat (skis creusés avec un rayon de plus de 18 m et avec une largeur minimum de 85 mm au patin).The manufacturing systems currently known have enabled this application successfully almost a hundred years later. This application to contemporary skis has made it possible to manufacture skis, the turns of which are more and more "cut", that is to say that the skids of the rear of the ski at the exit of the turn are progressively reduced. and very often non-existent. In this case, driving the turn is preferably carried out on the edge which provides a gain in precision and speed. More precisely, the tendency to widen the dimension line is measured by the increase in the difference between the width of the spatula area and the width of the skid area. One of the problems which the invention proposes to solve is that of the lack of versatility of the skis between their behavior on hard snow for carving type skis (hollow skis and with a width of 62 to 65 mm on the skate) and in snow deep for freeride type skis (hollow skis with a radius of 18 to 30 m, with a width of 68 to 75 mm at the waist) or still in deep snow skis of the so-called fat type (hollow skis with a radius of more than 18 m and with a minimum width of 85 mm on the skate).
D'une part la présente invention résout le problème de choix des skieurs, les skis du marché actuels étant moins performants en termes de polyvalence tous terrains par le fait qu'aucun modèle de ski proposé sur le marché utilise les paramètres de l' invention. Le skieur aura recours à un seul type de ski au lieu d'au moins deux paires actuellement pour obtenir un résultat au mieux aussi performant et moins ludique que l'invention.On the one hand, the present invention solves the problem of choosing skiers, the skis on the current market being less efficient in terms of all-terrain versatility by the fact that no ski model offered on the market uses the parameters of the invention. The skier will use a single type of ski instead of at least two pairs currently to obtain a result at best as efficient and less fun as the invention.
D'autre part, compte tenu des différentes évolutions des dimensions des skis, il apparaît un problème de stabilité lorsque le ski est à plat sur la neige et à grande vitesse. En effet, on observe une tendance au flottement transversal, qui s'avère perturbant pour le skieur et augmente les risques de chutes.On the other hand, given the various changes in the dimensions of the skis, there appears to be a stability problem when the ski is flat on snow and at high speed. Indeed, there is a tendency to transverse floating, which proves disturbing for the skier and increases the risk of falls.
La présente invention se propose de résoudre ce deuxième problème qui à trait à la stabilité transversale d'un ski relativement court, lorsque celui-ci est à plat sur la neige. La longueur de la spatule apportant des appuis latéraux plus conséquents.The present invention proposes to solve this second problem which relates to the transverse stability of a relatively short ski, when the latter is flat on the snow. The length of the spatula providing more substantial lateral support.
Par ailleurs, la pratique consistant à couper les virages, et à conduire les virages essentiellement sur la carre, laisse apparaître un problème de maintien dans le virage des extrémités des skis, en réduisant les dérapages ou les phénomènes de "broutage".Furthermore, the practice of cutting corners, and driving the turns mainly on the edge, reveals a problem of holding the ends of the skis in the turn, reducing skidding or "grazing" phenomena.
Ainsi, un troisième problème que se propose de résoudre l'invention est celui de l'accrochage, et donc de la rigidité en flexion et torsion adaptée, dans sa zone arrière, plus particulièrement dans sa zone avant par le poids d'une spatule accentuée, de manière à donner une pression supplémentaire au niveau des carres lors de la conduite et un meilleur amorti des vibrations. L'invention vise à résoudre simultanément ces trois problèmes en proposant un ski d'une longueur variant de cent soixante centimètres à moins de deux mètres, dont la tenue est fortement améliorée, que ce soit lorsqu'il est sur la carre ou lorsqu'il est en trace directe en augmentant la pression des extrémités avant et arrière du ski, en contrôlant les frottements transversaux.Thus, a third problem which the invention proposes to solve is that of the attachment, and therefore of the rigidity in flexion and torsion adapted, in its rear zone, more particularly in its front zone by the weight of an accentuated spatula. , so as to give additional pressure at the edges when driving and better vibration damping. The invention aims to solve these three problems simultaneously by proposing a ski with a length varying from one hundred and sixty centimeters to less than two meters, the grip of which is greatly improved, either when it is on the edge or when it is in direct trace by increasing the pressure of the front and rear ends of the ski, by controlling the transverse friction.
L'invention concerne un ski alpin comportant une zone spatule, une zone patin et une zone talon, et présentant :The invention relates to an alpine ski comprising a tip zone, a skate zone and a heel zone, and having:
un rayon au niveau de la carre latérale inférieur à 18O00 mma radius at the side edge of less than 1800 mm
Ce ski est de structure composite et est construit conformément aux connaissances actuelles de l'homme du métier.This ski is of composite structure and is built in accordance with current knowledge of the skilled person.
Ce ski se caractérise en ce qu'il comporte également une largeur minimale au niveau de la zone patin de 69 mm et une longueur développée de la zone de spatule représentant au minimum le 11,5 pour cent de la longueur totale développée du ski.This ski is characterized in that it also has a minimum width at the level of the pad area of 69 mm and a developed length of the tip region representing at least 11.5 percent of the total developed length of the ski.
Autrement dit, le ski conforme à l'invention intègre une spatule de dimension accentuée qui, à la fois assure un guidage longitudinal lorsque le ski est en trace directe, et qui confèrent à augmenter la pression sur les carres lors de la conduite du virage.In other words, the ski according to the invention integrates a spatula of accentuated dimension which, at the same time ensures a longitudinal guidance when the ski is in direct track, and which confer to increase the pressure on the edges when driving the turn.
De la sorte, on permet au ski de mieux résister aux déplacements transversaux lorsqu'il se trouve à plat sur la neige dure, et grâce à ce moyen, on confère au ski une capacité de mieux ouvrir la trace en neige profonde. Description sommaire des figuresIn this way, the ski is better able to resist transverse movements when it is flat on hard snow, and thanks to this means, the ski is given the ability to better open the trail in deep snow.
