Abstract

Boot comprising a shell (1) surrounding the foot and the heel and an upper (2) articulated on the shell. The shell is equipped, at the rear, with a framework comprising a part in the form of an arch (4) incorporated in the heel of the boot and two ascending lateral parts (6) connecting the ends of the arch to the articulation (3) of the upper on the shell. The parts (6) may be connected together by a part (7). <IMAGE>

Description

La présente invention a pour objet une chaussure de ski en matière plastique comprenant une coque entourant le pied et le talon et une tige articulée sur la coque et dont la coque est munie, à l'arrière, d'une armature comprenant une partie en forme d'arceau.The subject of the present invention is a plastic ski boot comprising a shell surrounding the foot and the heel and a rod articulated on the shell and the shell of which is provided, at the rear, with a frame comprising a shaped part. headband.

La tige est soit en une seule pièce, en forme de collier, soit en deux pièces, l'une recouvrant l'avant de la jambe et l'autre l'arrière et pouvant être largement basculée vers l'arrière pour le chaussage.The rod is either in one piece, in the form of a necklace, or in two pieces, one covering the front of the leg and the other the back and which can be largely tilted back for fitting.

La transmission des efforts de la jambe au ski lors de la prise de carre se faisant par la chaussure, notamment la coque, la rapidité et la précision de la transmission de ces efforts dépendent de la rigidité de la chaussure. Cette rigidité ne peut toutefois pas être augmentée sans augmentation de l'épaisseur de la matière plastique, c'est-à-dire du coût et du poids de la chaussure. En outre, la transmission des efforts se fait essentiellement par l'arrière du pied.The transmission of forces from the leg to the ski when the edge is taken up by the boot, in particular the shell, the speed and the accuracy of the transmission of these forces depend on the rigidity of the boot. This rigidity cannot however be increased without increasing the thickness of the plastic, that is to say the cost and the weight of the shoe. In addition, the transmission of forces takes place essentially through the rear of the foot.

Du document FR-A- 2 654 903, on connaît une chaussure de ski comprenant un arceau rigide en forme de U dont les branches obliques sont articulées dans la semelle et sur lesquelles est articulée la tige en forme de collier. La tige étant articulée sur une pièce rigide elle-même articulée sur une partie rigide de la chaussure, la chaussure présente de meilleures qualités techniques.From document FR-A-2 654 903, a ski boot is known comprising a rigid U-shaped arch whose oblique branches are articulated in the sole and on which the collar-shaped rod is articulated. The upper being articulated on a rigid part itself articulated on a rigid part of the shoe, the shoe has better technical qualities.

L'invention a pour but d'augmenter la rigidité de la coque de la chaussure dans la zone arrière du pied sans augmenter l'épaisseur de la matière plastique, voire en pouvant réduire cette épaisseur.The invention aims to increase the rigidity of the shell of the shoe in the rear region of the foot without increasing the thickness of the plastic, or even can reduce this thickness.

La chaussure selon l'invention est caractérisée en ce que la partie en forme d'arceau forme la partie supérieure du talon de la chaussure et que ses extrémités sont reliées à l'articulation de la tige sur la coque par deux parties latérales ascendantes.The shoe according to the invention is characterized in that the arch-shaped part forms the upper part of the heel of the shoe and that its ends are connected to the articulation of the upper on the shell by two ascending lateral parts.

La rigidité peut être encore augmentée en reliant les extrémités des parties ascendantes entre elles. L'ensemble d'une telle armature est de préférence réalisé en une seule pièce.The rigidity can be further increased by connecting the ends of the ascending parts together. The assembly of such a frame is preferably made in one piece.

Le dessin annexé représente une forme d'exécution de l'invention.The accompanying drawing represents an embodiment of the invention.

L'unique figure du dessin représente partiellement une chaussure de ski vue de 3/4 de l'arrière. Cette chaussure comprend une coque 1 entourant le pied et le talon et une tige 2, en forme de collier, articulée sur la coque en deux points opposés dont l'un, 3, est visible sur le dessin.The single figure in the drawing partially represents a ski boot viewed from 3/4 of the rear. This shoe comprises a shell 1 surrounding the foot and the heel and a rod 2, in the form of a collar, articulated on the shell at two opposite points, one of which, 3, is visible in the drawing.

La coque est munie d'une armature comprenant une partie inférieure 4 en forme d'arceau logée dans une gorge de la coque de manière à être intégrée au talon de la chaussure et formant la partie supérieure de ce talon, dont la partie inférieure 5 est constituée par la matière plastique de la coque. La hauteur totale du talon et la forme de l'ensemble des parties 4 et 5 correspondent aux normes. A partir des extrémités de la partie 4, s'étendent deux parties ascendantes obliques 6 aboutissant aux articulations 3 du collier 2 sur la coque. Les extrémités des parties 6 sont elle-mêmes reliées entre elles par une partie 7 épousant la forme arrondie de la coque et passant sous le collier 2.The shell is provided with a frame comprising a lower part 4 in the form of a hoop housed in a groove in the shell so as to be integrated into the heel of the shoe and forming the upper part of this heel, the lower part 5 of which is constituted by the plastic material of the shell. The total height of the heel and the shape of all parts 4 and 5 correspond to the standards. From the ends of the part 4, extend two oblique ascending parts 6 leading to the joints 3 of the collar 2 on the shell. The ends of the parts 6 are themselves connected to each other by a part 7 which conforms to the rounded shape of the shell and passes under the collar 2.

L'armature constituée des parties 4, 6, 7 peut être en métal, en matière synthétique ou minérale ou en un mélange de telles matières.The frame made up of parts 4, 6, 7 can be made of metal, synthetic or mineral material or a mixture of such materials.

Les articulations 3 traversant l'armature, ces articulations sont également renforcées.The joints 3 passing through the frame, these joints are also reinforced.

Si les parties 4 et 6 sont suffisamment rigides, la partie 7 de l'armature pourrait être éventuellement supprimée.If parts 4 and 6 are sufficiently rigid, part 7 of the reinforcement could possibly be removed.

Ce mode de renforcement de la coque est applicable à tous les types de chaussures.This method of strengthening the shell is applicable to all types of shoes.
