Description

L'invention concerne une chaussure de ski alpin.The invention relates to an alpine ski boot.

Les premières chaussures de ski, en cuir, étaient relativement souples. Elles offraient un bon confort et permettaient une marche aisée grâce à la souplesse de leur semelle. Afin d'assurer une bonne transmission des efforts entre le pied et le ski, c'est-à-dire de réduire la capacité de déformation de la chaussure, la semelle et la tige sont devenues de plus en plus rigides, la marche devenant par conséquent de moins en moins aisée. Avec l'apparition des chaussures en matière plastique, la tige, mais plus particulièrement la semelle, a acquis une rigidité assurant une excellente interface entre le pied et le ski par l'intermédiaire de la fixation du ski, mais rendant une marche normale difficile en raison du manque total de flexion de la semelle au niveau de l'articulation métatarsophalangienne.The first ski boots, in leather, were relatively flexible. They offered good comfort and allowed easy walking thanks to the flexibility of their sole. In order to ensure good transmission of efforts between the foot and the ski, i.e. reduce the deformation capacity of the shoe, the sole and upper have become more and more rigid, walking therefore becoming less and less less easy. With the appearance of shoes in plastic, the rod, but more particularly the sole, has acquired a rigidity ensuring excellent interface between foot and ski by through the binding of the ski, but making a normal walking difficult due to the total lack of sole flexion at the joint metatarsophalangeal.

Depuis un certain nombre d'années, on cherche à faciliter la marche avec des chaussures de ski alpin en plastique par différentes mesures. Dans le brevet EP 0 664 969, il est proposé de prévoir une zone souple formant charnière dans la zone métatarsophalangienne de la semelle rigide et de diviser la coque de la chaussure en deux parties articulées au niveau de ladite articulation, ces deux parties étant en outre reliées par un dispositif permettant de bloquer l'articulation. For a number of years, we have sought to make walking easier with alpine ski boots plastic by different measures. In patent EP 0 664 969, it is proposed to provide a flexible zone forming a hinge in the metatarsophalangeal area of the rigid sole and split the shell of the shoe in two parts articulated at said joint, these two parts being further connected by a device to block the joint.

Une chaussure conçue selon le même principe est également connue du brevet US 5 572 806. Cette chaussure diffère de la précédente en ce que le dispositif de blocage est monté coulissant dans l'épaisseur de la semelle. De telles chaussures ne présentent pas une véritable souplesse permettant un déroulement naturel du pied lors de la marche. En outre, en ce qui concerne la marche, elles sont lourdes et peu confortables.A shoe designed according to the same principle is also known from US Patent 5,572,806. shoe differs from the previous in that the locking device is slidably mounted in the thickness of the sole. Such shoes do not not have a real flexibility allowing a natural course of the foot when walking. In besides, when it comes to walking, they are heavy and not very comfortable.

Une autre approche du problème mettant de côté les palliatifs des solutions mentionnées ci-dessus, est décrite dans les brevets FR 2 130 644 et WO-A-9735494. Elle consiste en une sorte de boítier auxiliaire dans lequel on enferme une chaussure à tige et semelle souple.Another approach to the problem putting aside the solutions mentioned above, is described in patents FR 2 130 644 and WO-A-9735494. It consists of a kind of auxiliary box in which we enclose a shoe with a flexible upper and sole.

Les chaussures destinées à la pratique du ski de fond présentent certes une souplesse au niveau de la zone métatarsophalangienne de manière à permettre un déroulement du pied avec un minimum de résistance. Ces chaussures ne sont toutefois fixées qu'à l'avant, de sorte que la semelle ne doit pas présenter une rigidité longitudinale comme c'est le cas des semelles de chaussures de ski dans une fixation de ski conventionnelle à butée avant et talonnière, semelles qui doivent être suffisamment rigides pour supporter la poussée longitudinale exercée par la fixation et la poussée verticale exercée par la pédale du frein.Footwear intended for cross-country skiing certainly have flexibility in the area metatarsophalangeal so as to allow a unfolding of the foot with a minimum of resistance. These shoes are only attached to the front, so that the sole should not have stiffness longitudinal as is the case with the soles of ski boots in a ski binding conventional toe and heel stop, soles which must be rigid enough to support the longitudinal thrust exerted by the fixing and the vertical thrust exerted by the brake pedal.

Aujourd'hui, les personnes pratiquant un ski de loisir aimeraient trouver sur le marché une chaussure légère et confortable permettant à la fois une marche aisée et une pratique du ski dans de bonnes conditions lorsque la chaussure est fixée à un ski au moyen d'une fixation de type conventionnel.Today, people practicing recreational skiing would like to find a light shoe on the market and comfortable allowing both easy walking and skiing in good conditions when the boot is attached to a ski by means of a binding of conventional type.

L'invention a pour but de proposer une chaussure de ski alpin répondant à cette attente.The invention aims to provide a ski boot Alpine meeting this expectation.

La chaussure de ski alpin selon l'invention elle comprend une tige souple en forme de botte enveloppant le pied, une armature en forme de berceau s'étendant latéralement autour de la partie inférieure de la tige, du talon à l'extrémité avant de la chaussure, et présentant une semelle partiellement ajourée, un talon muni d'un trottoir arrière, une partie avant munie d'un trottoir avant, ainsi que deux parties latérales s'étendant de la région de la voûte plantaire à la région malléolaire et une partie postérieure reliant la région supérieure des parties latérales au talon, de manière à former un système triangulé de chaque côté de la tige, les côtés de cette armature étant également ajourés, un collier articulé sur les parties latérales de l'armature et entourant la partie supérieure de la tige, caractérisée en ce que l'armature est fixée inamoviblement à la tige souple par une matière plastique souple injectée autour de l'armature et traversant les parties ajourées de l'armature pour se lier à la tige souple, aussi bien dessous que sur les côtés.The alpine ski boot according to the invention it includes a flexible rod form of boot wrapping the foot, a frame in cradle shape extending laterally around the lower part of the upper, from the heel to the end front of the shoe, and having a sole partially openwork, a heel with a sidewalk rear, a front section fitted with a front sidewalk, as well as two side parts extending from the arch region to the malleolar region and a posterior part connecting the upper region of side parts at the heel, so as to form a triangulated system on each side of the rod, the sides of this frame also being openwork, a necklace articulated on the lateral parts of the frame and surrounding the upper part of the rod, characterized in that the armature is fixed irremovably to the flexible rod by a flexible plastic material injected around the frame and crossing the openwork parts of the frame to bind to the flexible rod, both underneath and on the sides.

La matière plastique souple injectée autour de l'armature forme donc une semelle sous l'armature. Cette semelle étant en outre généralement munie de deux plaques de caoutchouc relativement dures fixées respectivement sous la talon et sous la partie antérieure de la semelle, la matière plastique souple injectée forme une couche élastique amortissant les chocs.The flexible plastic material injected around the frame therefore forms a sole under the frame. This sole being also generally provided with two relatively hard rubber plates attached respectively under the heel and under the part anterior sole, flexible plastic injected forms an elastic layer absorbing the shocks.

Selon un mode d'exécution préféré de l'invention, les parties latérales de l'armature présentent chacune une patte s'étendant en direction l'une de l'autre sur la partie inférieure du cou de pied, ces pattes étant destinées à recevoir un dispositif de serrage qui les relie.According to a preferred embodiment of the invention, the lateral parts of the frame each have a leg extending towards each other on the lower part of the instep, these legs being intended to receive a clamping device which connects.

L'armature peut présenter une partie amincie en retrait de la partie formant la semelle, le talon et l'avant du pied, et ajourée, de telle sorte que la matière plastique souple injectée ne recouvre pas la partie inférieure plus épaisse de l'armature.The frame may have a tapered recessed portion of the part forming the sole, the heel and the front of the foot, and perforated, so that the material injected flexible plastic does not cover the part thicker bottom of the frame.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.The accompanying drawing shows, by way of example, a mode of the invention.

La figure 1 est une vue en perspective de la chaussure, non encore équipée de boucles et de courroie de bas de jambe.FIG. 1 is a perspective view of the shoe, not yet fitted with buckles and bottom strap leg.

La figure 2 est un éclaté de la figure 1, sans la matière souple injectée autour de l'armature.Figure 2 is an exploded view of Figure 1, without the flexible material injected around the frame.

La chaussure représentée au dessin est constituée essentiellement d'une tige souple 1, d'une armature 2 et d'un collier 3 articulé sur l'armature en deux points opposés 4 et 5 situés dans la région malléolaire.The shoe represented in the drawing is made up essentially a flexible rod 1, a frame 2 and a collar 3 articulated on the frame in two opposite points 4 and 5 located in the region malleolus.

La tige souple 1 a été représentée très schématiquement sous la forme d'une botte fermée. En réalité, cette botte sera ouverte sur le devant et se fermera par deux rabats et éventuellement une languette passant sur le cou-de-pied. La tige 1 peut être en matière plastique souple revêtue d'un rembourrage intérieur ou en un matériau tissé imprégné d'une matière plastique ou réalisée de toute autre manière.The flexible rod 1 has been shown very schematically in the form of a closed boot. In reality, this boot will be open on the front and will close by two flaps and possibly a tab passing over the kick. Rod 1 can be made of plastic soft covered with interior padding or in a woven material impregnated with plastic or performed in any other way.

L'armature 2 est réalisée, de préférence, en polyuréthanne comme les coques de chaussures de ski connues. L'armature 2 constitue un berceau pour la tige 1. Ce berceau s'étend latéralement autour de la partie inférieure de la tige, du talon à l'extrémité avant de la chaussure et présente une semelle ajourée 6, entre le talon 7, muni d'un trottoir 8, et une partie avant 9, également munie d'un trottoir 10, les trottoirs 8 et 10 étant destinés à recevoir respectivement la fixation arrière et la fixation avant d'une fixation de ski. La partie avant 9 présente en outre une partie renforcée verticale arrondie 11 destinée à recevoir l'appui des mâchoires d'une fixation avant. Le berceau formé par l'armature présente une paroi latérale 12 ajourée par des trous 13 sur ses deux côtés. La partie ajourée est un peu plus mince que le bord inférieur de l'armature.The frame 2 is preferably made of polyurethane like ski boot shells known. The frame 2 constitutes a cradle for the rod 1. This cradle extends laterally around the part lower part of the upper, from the heel to the front end of the shoe and has a perforated sole 6, between the heel 7, provided with a sidewalk 8, and a front part 9, also provided with a sidewalk 10, the sidewalks 8 and 10 being intended respectively to receive the fixing rear and the front binding of a ski binding. The front part 9 also has a reinforced part 11 rounded vertical intended to receive the support of front fixing jaws. The cradle formed by the frame has a side wall 12 perforated by holes 13 on both sides. The openwork part is a little thinner than the bottom edge of the frame.

L'armature 2 présente en outre deux parties latérales ascendantes 14 et 15 s'étendant à partir de la région correspondant à la voûte plantaire en direction de la zone malléolaire et vers l'arrière où elles rejoignent une partie postérieure 16 s'étendant sur le dos de la chaussure et reliant les parties latérales 14 et 15 à la région de l'armature comprenant le talon 7. Le bord du berceau, les parties latérales 14 et 15 et la partie postérieure 16 forment, de chaque côté de la chaussure, un système triangulé donnant à la chaussure la rigidité nécessaire à une bonne conduite du ski. Les points d'articulation 4 et 5 sont situés dans les parties latérales 14 et 15. L'armature présente en outre deux pattes 17 et 18 s'étendant respectivement à partir des parties latérales 14 et 15 sur la partie inférieure du cou-de-pied, en direction l'une de l'autre. Ces pattes 17 et 18 sont destinées à recevoir une boucle de fermeture et de serrage. L'armature 2 présente en outre, à l'arrière, une languette 19, pouvant fléchir vers l'arrière et destinée à venir s'intercaler entre le collier 3 et la tige 1 dans la zone du tendon d'Achille.The frame 2 also has two side parts ascending 14 and 15 extending from the region corresponding to the arch towards the malleolar zone and towards the rear where they join a rear part 16 extending over the back of the shoe and connecting the side parts 14 and 15 to the region of the frame including the heel 7. The edge of the cradle, the side parts 14 and 15 and the part rear 16 form, on each side of the shoe, a triangulated system giving the shoe rigidity necessary for a good conduct of the ski. Dots of articulation 4 and 5 are located in the parts side 14 and 15. The frame also has two legs 17 and 18 extending respectively from the side parts 14 and 15 on the lower part of the instep, towards each other. These legs 17 and 18 are intended to receive a loop of closing and tightening. The frame 2 presents in in addition, at the rear, a tongue 19, which can flex backwards and intended to come between the collar 3 and the rod 1 in the tendon area Achilles.

Après avoir placé la tige 1 dans l'armature 2, l'armature et la tige sont solidarisées par l'injection d'une matière plastique souple 20 autour de la partie en forme de berceau de l'armature, de telle manière que cette matière plastique 20 traverse aussi bien les parties latérales ajourées 13 de l'armature 2 que la semelle 6, en formant une ceinture autour de l'armature. La tige 1 et l'armature 2 sont ainsi parfaitement liées dans toute la région plantaire. La matière plastique 20 est, par exemple, du polyuréthanne expansé. Comme on peut le voir à la figure 1, la matière plastique 20 s'étend également sous l'armature, en particulier dans sa région médiane où elle permet de conserver une certaine souplesse qui facilite la marche.After placing the rod 1 in the frame 2, the frame and the rod are secured by injection flexible plastic 20 around the part in the form of a cradle of the frame, so that this plastic material 20 crosses both perforated side parts 13 of the frame 2 that the sole 6, forming a belt around the armature. The rod 1 and the frame 2 are thus perfectly linked throughout the plantar region. The plastic material 20 is, for example, polyurethane expanded. As can be seen in Figure 1, the plastic material 20 also extends under the frame, especially in its middle region where it allows maintain a certain flexibility which facilitates the market.

Le collier 3 est également ajouré. Il est muni, vers l'avant, d'une paire de pattes 21, 22 venant entourer la tige 1 et destinées à recevoir une boucle. Dans sa partie supérieure, le collier 3 présente deux passants 23 et 24 destinés à recevoir une courroie, de préférence une courroie se refermant par un système VELCRO (Marque déposée), courroie servant, de manière connue, d'appui tibial.The collar 3 is also openwork. It is provided, towards the front, a pair of legs 21, 22 surrounding the rod 1 and intended to receive a loop. In his upper part, collar 3 has two loops 23 and 24 intended to receive a belt, preferably a strap closing by a system VELCRO (registered trademark), belt used, so known, tibial support.

La chaussure est en outre munie, de manière connue, d'une plaquette de talon 25 et d'une plaquette avant 26, toutes deux en caoutchouc dur.The shoe is also provided, in a known manner, a heel plate 25 and a front plate 26, both made of hard rubber.

La chaussure décrite est susceptible de nombreuses variantes d'exécution sans sortir du cadre de l'invention. En particulier, l'armature 2 pourrait être réalisée en multi-injection de manière à être flexible dans la zone médiane pour faciliter la marche. Elle pourrait présenter des zones évidées transversalement dans le même but. L'armature 2 pourrait en outre présenter des parties saillantes traversant la matière 20 vers le bas de manière à remplacer la talonnette 25 et la plaque avant 26, ces parties traversantes pouvant faire saillie sous la semelle et constituer ainsi des crampons.The shoe described is likely to have many variants without departing from the scope of the invention. In particular, frame 2 could be performed in multi-injection so as to be flexible in the middle area to facilitate walking. She could present transversely hollowed out areas for the same purpose. The frame 2 could also present protruding parts crossing the material 20 down so as to replace the heel 25 and the front plate 26, these through parts being able to protrude under the sole and thus constitute studs.

La matière 20 peut être un matériau amortisseur.The material 20 can be a damping material.
