Abstract
Description
La présente invention concerne une chaussure de ski à volume variable munie de boucles de serrage.The present invention relates to a variable volume ski boot provided with tightening loops.
Le niveau très élevé atteint actuellement par l'élite des coureurs dans les compétitions internationales de ski et la performance des produits utilisés en compétition, tant en ce qui concerne les skis que le reste de l'équipement, font que les meilleurs coureurs ne sont souvent séparés que par quelques centième de seconde. La recherche de forme aérodynamique joue dès lors un rôle de plus en plus important, puisqu'une bonne aérodynamique permet de gagner les quelques centièmes de seconde qui permettront d'obtenir la victoire. Or, dans cette recherche de l'amélioration des formes aérodynamique, on a jusqu'ici négligé les boucles des chaussures qui constituent des aspérités à la surface de la chaussure, aspérités qui exercent un freinage lors de vitesses élevées.The very high level currently reached by the elite of runners in international ski competitions and the performance of the products used in competition, both in terms of skis and the rest of the equipment, means that the best runners are often not separated only by a few hundredths of a second. The search for aerodynamic form therefore plays an increasingly important role, since good aerodynamics allows you to gain the few hundredths of a second which will allow you to obtain victory. However, in this search for the improvement of aerodynamic shapes, we have so far neglected the shoe loops which constitute asperities on the surface of the shoe, asperities which exert braking at high speeds.
Il est certes connu, notamment du brevet US 3 529 368 et du brevet FR 2 638 338 de recouvrir une boucle ou un laçage de chaussure par une couverture souple, mais ceci, dans le premier cas, exclusivement dans le but d'assurer une certaine étanchéité à la chaussure et, dans le second cas, de protéger les moyens de fermeture de la chaussure contre un risque d'accrochage.It is certainly known, in particular from US patent 3,529,368 and from patent FR 2,638,338 to cover a buckle or a shoe lacing with a flexible cover, but this, in the first case, exclusively for the purpose of ensuring a certain tightness to the shoe and, in the second case, to protect the closing means of the shoe against a risk of snagging.
Le but de la présente invention n'est pas de protéger les boucles de la chaussure, ni d'améliorer l'étanchéité de celle-ci, mais d'améliorer le coefficient de pénétration (Cx) de la chaussure dans l'air.The object of the present invention is not to protect the buckles of the shoe, or to improve the tightness thereof, but to improve the penetration coefficient (Cx) of the shoe in the air.
La chaussure selon l'invention est caractérisée en ce qu'elle comprend une pièce auxiliaire au moins semi-rigide rapportée sur la coque assurant, au moins de manière approchée, une continuité aérodynamique de la partie de la coque portant les boucles, au moins en position fermée des boucles.The shoe according to the invention is characterized in that it comprises an at least semi-rigid auxiliary piece attached to the hull ensuring, at least approximately, an aerodynamic continuity of the part of the hull carrying the buckles, at least in closed position of the buckles.
La pièce auxiliaire rigide rapportée peut être constituée d'un capot articulé à l'avant ou sur le côté de la chaussure et venant recouvrir les boucles en position rabattue et pouvant être relevé pour l'ouverture des boucles, ou d'un doublage présentant des découpes dans lesquelles les boucles sont noyées, ce doublage n'étant, de préférence, pas fixé sur tout son pourtour ou toute sa surface de manière à ne pas gêner le desserrage de la coque lors de l'ouverture des boucles, ou encore d'un capot rigide maintenu en position par les boucles passant sur des ponts prévus à cet effet sur le capot.The attached rigid auxiliary part may consist of a cover hinged at the front or on the side of the shoe and covering the buckles in the folded position and which can be raised to open the buckles, or a lining having cutouts in which the loops are embedded, this doubling is preferably not fixed over its entire periphery or its entire surface so as not to hinder the loosening of the shell when the loops open, or a rigid cover held in position by the loops passing over bridges provided for this purpose on the cover.
Que la pièce auxiliaire soit un capot ou un doublage, elle sera mince et légère, de manière à ne pas augmenter sensiblement le poids de la chaussure. Le doublage sera de préférence lui-même doublé intérieurement d'une mousse synthétique et fixé à la coque exclusivement sur son pourtour.Whether the auxiliary part is a hood or a lining, it will be thin and light, so as not to significantly increase the weight of the shoe. The lining will preferably be lined internally with a synthetic foam and fixed to the shell exclusively on its periphery.

Les figures 1 à 3 représentent une chaussure de ski constituée d'une coque 1 à volume variable dont l'ouverture longitudinale sur le pied est fermée par deux rabats 2 et 3, et d'une tige 4 en forme de collier articulée en 5 sur la coque 1. Cette chaussure, de type courant, peut être fermée et serrée au moyen de deux boucles 6 et 7 passant par dessus les rabats 2 et 3 et de deux boucles 8 et 9 pour le serrage du collier 4.Figures 1 to 3 show a ski boot consisting of a
Près de l'extrémité avant de la coque 1 est articulé un capot 10 en matériau rigide ou semi-rigide présentant, à son extrémité opposée à son articulation, deux trous opposés 11 situés de chaque côté du capot. Chacun de ces trous 11 est destiné à venir s'engager sur un téton 12 prévu de chaque côté de la coque pour le maintien du capot 10 en position rabattue sur la coque. Dans cette position rabattue, représentée à la figure 1, les boucles 6 et 7 sont complètement recouvertes et le dessus de la coque présente une surface aérodynamique lisse et continue.Near the front end of the
L'articulation du capot 10 à l'avant de la chaussure est réalisée au moyen d'une garniture d'étanchéité 13 en caoutchouc ou autre élastomère. Les chaussures de ce type comprennent généralement une garniture d'étanchéité engagée entre l'extrémité avant des rabats 2 et 3 et la coque. Dans le cas particulier, la garniture 13 présente, en plus d'une partie 13a constituant la garniture proprement dite, une languette extérieure 13b présentant au moins un téton 13c engagé dans au moins un trou du capot 10, de telle sorte que le capot 10 est fixé à la languette 13b.The articulation of the
Une deuxième forme d'exécution est représentée aux figures 4 et 5. La chaussure représentée ne diffère de la première forme d'exécution que par la pièce auxiliaire rapportée. Celle-ci est constituée d'un doublage léger 14 présentant des découpes 15 et 16 dans lesquelles sont logées les boucles 6 et 7 de la coque. Le doublage 15 est revu intérieurement de mousse et il est fixé par collage ou soudure d'un zone marginale sur le côté intérieur de la chaussure et à l'avant de celle-ci. Le doublage 14 présente une zone souple 14a sur le côté extérieur de la chaussure, cette zone souple pouvant se relever pour faciliter le chaussage.A second embodiment is shown in Figures 4 and 5. The shoe shown differs from the first embodiment only in the added auxiliary part. This consists of a
Selon une troisième forme d'exécution représentée à la figure 6, la pièce auxiliaire est constituée d'un capot rigide 17 articulé latéralement sur des surépaisseurs 18 et 19 à l'extrémité des crémaillères d'accrochage des boucles 6 et 7. Lorsqu'il est rabattu sur les boucles 6 et 7, le capot 17 peut être maintenu en place par divers moyens, par exemple des trous analogues aux trous 11 venant se fixer sur des tétons analogues aux tétons 12.According to a third embodiment shown in FIG. 6, the auxiliary part consists of a
Selon une quatrième forme d'exécution représentée à la figure 7, la pièce auxiliaire est constituée d'un capot amovible 20 en matériau léger moulé. Au-dessus des boucles 6 et 7, le capot 20 n'est pas continu mais présente, au-dessus de la boucle 6, deux discontinuités 21 et 22 formées par deux découpes entre lesquelles s'étend un pont sur lequel passe la boucle 6. De même, la boucle 7 traverse deux découpes 23 et 24 et passe par dessus un pont entre ces deux découpes. Le capot 20 est ainsi maintenu en place par les boucles. Il se relève et se rabat avec les boucles.According to a fourth embodiment shown in Figure 7, the auxiliary part consists of a
