Abstract

A boot (9) for cross-country skiing comprises a sole (26) having an extension (8) towards the front, permitting the fastening of the boot (9) on the ski (5), so as to enable the skier to walk by raising the heels. In order to ensure great flexibility in the zone located at the front of the foot, the sole (26) and its extension (8) are obtained directly by moulding in plastic. <IMAGE>

Chaussure selon la revendication 2, caractérisée en ce que la zone de plus faible épaisseur est limitée par un épaulement servant d'appui à l'organe de verrouillage qui maintient le prolongement de la semelle dans l'arceau de fixation.5. Shoe according to claim 2, characterized in that the thinner zone is bounded by a shoulder acting as a support for the locking member which holds the extension of the sole in the fastening hoop. La présente invention est relative à une chaussure de ski de fond ou de tourisme destinée à être utilisée avec une fixation du type de celles où la chaussure est maintenue par un prolongement de la semelle, situé à l'avant de la chaussure, qui s'engage dans un arceau de même forme solidaire du ski.The present invention relates to a cross-country ski or touring boot intended to be used with a binding of the type where the boot is held by an extension of the sole, located at the front of the boot, which is engages in a hoop of the same shape integral with the ski. On connaît déjà des dispositifs de fixation tels que celui décrit dans le brevet allemand N° 748443, dans lesquels une pièce métallique est rapportée à l'extrémité avant de la chaussure, cette pièce s'engageant, éventuellement avec un jeu, sur un organe de fixation solidaire du ski. Ces types de fixation présentent l'inconvénient d'être lourds, encombrants, d'une fabrication compliquée et de ne pas permettre une flexibilité de la partie avant de la semelle tout en assurant un guidage convenable du pied par rapport au ski.Binding devices such as that described in German patent No. 748443 are already known, in which a metal part is attached to the front end of the shoe, this part engaging, possibly with a play, on a member of binding attached to the ski. These types of binding have the disadvantage of being heavy, bulky, complicated to manufacture and of not allowing flexibility of the front part of the sole while ensuring suitable guidance of the foot relative to the ski. La chaussure de ski selon l'invention est caractérisée en ce que la semelle et son prolongement sont directement obtenus par un moulage en matière plastique qui assure une flexibilité de la zone se trouvant en avant du pied.The ski boot according to the invention is characterized in that the sole and its extension are directly obtained by molding in plastics material which ensures flexibility of the area located in front of the foot. Dans un mode de réalisation particulier, la partie du prolongement avant de la chaussure qui s'engage dans l'arceau est réunie à la semelle proprement dite par une zone de plus faible épaisseur qui augmente la flexibilité et facilite le soulèvement du talon.In a particular embodiment, the part of the front extension of the shoe which engages in the hoop is joined to the sole proper by a zone of thinner thickness which increases flexibility and facilitates raising of the heel. Cette zone de plus faible épaisseur est limitée par un épaulement qui peut être avantageusement utilisé comme surface d'appui pour l'organe de verrouillage qui immobilise le prolongement de la semelle dans l'arceau.This thinner zone is limited by a shoulder which can advantageously be used as a bearing surface for the locking member which immobilizes the extension of the sole in the hoop. Dans un mode de réalisation particulier, la chaussure est caractérisée en ce que la partie inférieure avant de la semelle et de son prolongement présentent un dégagement dont la profondeur correspond à l'épaisseur de la plaque de base qui supporte l'arceau.In a particular embodiment, the boot is characterized in that the lower front part of the sole and of its extension have a recess, the depth of which corresponds to the thickness of the base plate which supports the hoop. Dans le but de mieux comprendre l'invention, on va décrire maintenant à titre d'illustration et sans caractère limitatif, un mode de réalisation représenté au dessin.In order to better understand the invention, we will now describe by way of illustration and without limitation, an embodiment shown in the drawing. La fig. 1 est une vue de dessus d'une fixation pouvant recevoir une chaussure selon l'invention.fig. 1 is a top view of a binding that can receive a shoe according to the invention. La fig. 2 est une vue latérale de cette fixation, selon II-II de la fig. 1, dans laquelle se trouve engagé le prolongement d'une semelle de chaussure selon l'invention.fig. 2 is a side view of this binding, according to II-II of FIG. 1, in which is engaged the extension of a shoe sole according to the invention. Dans la fixation représentée aux fig. 1 et 2, la chaussure est maintenue par le fait que le prolongement avant de la semelle 26 s'engage dans un arceau 6 comportant deux parties verticales 6a et 6b qui sont prolongées par des ailes divergentes 15 et 16.In the binding represented in FIGS. 1 and 2, the shoe is held in place by the fact that the front extension of the sole 26 engages in a hoop 6 comprising two vertical parts 6a and 6b which are extended by diverging wings 15 and 16. La fixation de la chaussure est obtenue par une broche 21 en forme d'épingle qui traverse horizontalement les parties verticales 6a et 6b de l'arceau 6, ainsi que le prolongement 8 de la semelle.The fixing of the shoe is obtained by a pin 21 in the form of a pin which crosses horizontally the vertical parts 6a and 6b of the hoop 6, as well as the extension 8 of the sole. A la fig. 2, on retrouve le ski 5, la plaque 1 qui supporte l'arceau 6 et les ailes 15 et 16. Conformément à l'invention, la semelle de la chaussure est munie d'un prolongement avant 8 qui est obtenu par moulage en une seule pièce avec la semelle 26, par exemple par injection de matière plastique.In fig. 2, we find the ski 5, the plate 1 which supports the arch 6 and the wings 15 and 16. In accordance with the invention, the sole of the shoe is provided with a front extension 8 which is obtained by molding in one one piece with the sole 26, for example by injection of plastic material. Conformément à un mode de réalisation particulier de l'invention, la semelle proprement dite 26 est réunie, par une zone 30 de plus faible épaisseur, au prolongement 8 qui est maintenu dans l'arceau In accordance with a particular embodiment of the invention, the actual sole 26 is joined, by a zone 30 of thinner thickness, to the extension 8 which is held in the hoop 6. On confère ainsi une flexibilité à l'avant de la chaussure, qui facilite le soulèvement du talon, comme cela est représenté en trait interrompu.6. This gives flexibility to the front of the shoe, which facilitates the raising of the heel, as shown in broken line. Pour permettre un appui correct de la semelle sur le ski, dans le mode de réalisation représenté à la fig. 2, la partie avant de la semelle présente en 31 un dégagement dont la profondeur correspond �� l'épaisseur de la plaque 1. Dans le mode de réalisation représenté, la partie avant 31 de la semelle en matière plastique enrobe le pourtour de la chaussure, ce qui contribue ainsi à donner à la semelle une flexibilité progressive en allant de l'avant vers l'arrière de la chaussure.To allow correct support of the sole on the ski, in the embodiment shown in FIG. 2, the front part of the sole has at 31 a recess, the depth of which corresponds to the thickness of the plate 1. In the embodiment shown, the front part 31 of the plastic material sole coats the periphery of the shoe , which thus helps to give the sole a progressive flexibility going from the front to the back of the shoe. Comme on peut le voir à la fig. 2, la zone 30 de plus faible épaisseur forme un épaulement en direction de l'arceau qui peut être utilisé pour le maintien de la chaussure sur le ski au moyen du dispositif de fixation décrit dans le brevet N° 614632. La forme de cet épaulement est évidemment adaptée à la forme de l'organe de verrouillage du dispositif qui y prend appui.As can be seen in fig. 2, the thinner zone 30 forms a shoulder in the direction of the hoop which can be used to hold the boot on the ski by means of the binding device described in patent No. 614632. The shape of this shoulder is obviously adapted to the shape of the locking member of the device which bears against it. 22 55 1010 1515 2020 2525 3030 3535 4040 4545 5050 RR 1 feuille dessins1 drawing sheet
