Abstract

Ski boot comprising auxiliary means of wedging of at least one part of the foot, constituted by at least one cam (10) mounted rotationally between the boot and the inner boot and operable from the oustide. <IMAGE>

Description

La présente invention a pour objet une chaussure de ski comprenant un chausson intérieur de confort et des moyens auxiliaires de calage d'au moins une partie du pied, ces moyens étant ajustables de l'extérieur.The present invention relates to a ski boot comprising an inner comfort liner and auxiliary means for wedging at least a part of the foot, these means being adjustable from the outside.

Pour un bon guidage du ski, il est essentiel que le pied du skieur soit parfaitement maintenu dans la chaussure. Il doit en outre également être maintenu en place lors de la flexion de la jambe vers l'avant, flexion qui a tendance à soulever le talon. A cet effet des moyens auxiliaires de maintien du talon et de l'avant pied ont déjà été proposés.For good ski guidance, it is essential that the skier's foot is perfectly held in the boot. It should also be held in place when bending the leg forward, which tends to lift the heel. To this end, auxiliary means for holding the heel and the forefoot have already been proposed.

En ce qui concerne le calage du talon on a déjà propo­ser d'amincir la chaussure dans des zones situées entre les malléoles, le talon et le tendon d'Achille et d'exercer sur ces zones amincies une pression au moyen de deux organes d'appui reliés par une boucle permet­tant d'exercer une pression variable sur les zones amincies et par là sur le chausson intérieur. Une telle chaussure est décrite dans le brevet FR-2 334 315. Les moyens utilisés sont relativement complexes et encom­brants. Ils nécessitent en outre des amincissements de la coque de la chaussure en un endroit fortement sollicité et qui réduisent sa rigidité et la rendent fragile. Compte tenu de ces inconvénients, certains constructeurs se sont détournés d'une telle solution pour adopter un système de cales amovibles montées en­tre la paroi de la tige de la chaussure et le rembour­rage fixé sur cette tige, comme décrit et représenté dans la demande de brevet FR-2 608 384.As regards the wedging of the heel, it has already been proposed to thin the shoe in zones situated between the malleoli, the heel and the Achilles tendon and to exert pressure on these thinned zones by means of two organs of support connected by a loop allowing to exert a variable pressure on the thinned areas and thereby on the inner liner. Such a shoe is described in patent FR-2 334 315. The means used are relatively complex and bulky. They also require thinning of the shell of the shoe in a highly stressed place which reduces its rigidity and makes it fragile. Given these drawbacks, some manufacturers have turned away from such a solution to adopt a system of removable wedges mounted between the wall of the upper of the shoe and the padding fixed on this upper, as described and represented in the patent application. FR-2 608 384.

De telles cales ne sont toutefois pas immédiatement ajustables, par l'utilisateur, de l'extérieur de la chaussure.However, such wedges are not immediately adjustable, by the user, from the outside of the shoe.

Il est également connu, dans une chaussure à chaussage par l'arrière comprenant un bas de coque sur lequel est articulé une demi-tige arrière, de bloquer le talon au moyen d'un dispositif à vis agissant sur une languette solidaire du bas de coque (FR 2 562 395). La pression s'exerçant centralement sur le talon d'Achille, elle est forcément limitée. Le brevet AT-385 185 propose également d'utiliser un dispositif à vis dirigé sur le tendon d'Achille mais agissant sur des languettes par l'intermédiaire de deux bras. Le dispositif occupe un volume considérable dans la chaussure. Les deux dispo­sitifs mentionnés ci-dessus ne permettent en outre pas d'ajuster différemment les deux côtés du talon.It is also known, in a shoe with a rear boot comprising a shell bottom on which is articulated a rear half-upper, to block the heel by means of a screw device acting on a tongue integral with the shell bottom (FR 2,562,395). The pressure being exerted centrally on the Achilles heel, it is necessarily limited. Patent AT-385,185 also proposes to use a screw device directed on the Achilles tendon but acting on tongues by means of two arms. The device occupies a considerable volume in the shoe. The two devices mentioned above do not allow the two sides of the heel to be adjusted differently.

Il est également connu de maintenir ou de caler l'avant-pied au moyen d'une tige filetée entraînable en rotation de l'extérieur et coopérant avec un écrou solidaire d'une sangle s'étendant sur une partie du pourtour de l'avant-pied (FR 2 548 877, FR 2 547 487 et FR 2 608 903). La tige filetée peut également coopérer avec deux écrous respectivement solidaires de deux sangles ou de deux plaques d'appui (FR 2 469 885 et FR 2 381 483). Ces dispositifs sont relativement compli­qués et ne garantissent pas une immobilisation du pied dans la chaussure ou alors seulement contre l'une des parois latérales intérieures de la coque de la chaussu­re. Ces dispositifs sont en outre sensibles au gel.It is also known to hold or wedge the forefoot by means of a threaded rod which can be rotated from the outside and which cooperates with a nut secured to a strap extending over part of the periphery of the front. -foot (FR 2 548 877, FR 2 547 487 and FR 2 608 903). The threaded rod can also cooperate with two nuts respectively secured to two straps or two support plates (FR 2 469 885 and FR 2 381 483). These devices are relatively complicated and do not guarantee immobilization of the foot in the shoe or then only against one of the inner side walls of the shell of the shoe. These devices are also sensitive to frost.

Reprenant l'idée d'un calage réglable immédiatement de l'extérieur de la chaussure, la présente invention a pour but de réaliser ce calage par des moyens aussi simples que possible, peu sensibles au gel, à réglage continu et permettant un ajustage différencié des deux côtés du talon, respectivement de l'avant-pied, lors­qu'ils sont présents de chaque côté de la chaussure.Taking up the idea of an adjustable wedging immediately from the outside of the shoe, the present invention aims to achieve this wedging by means also simple as possible, not very sensitive to frost, continuously adjustable and allowing differentiated adjustment of the two sides of the heel, respectively of the forefoot, when they are present on each side of the shoe.

La chaussure selon l'invention est caractérisée par le fait que les moyens auxiliaires de calage sont consti­tués par au moins une came montée rotativement entre la chaussure et le chausson et solidaires d'un pivot tra­versant la chaussure et muni à l'extérieur, d'un moyen permettant son entraînement en rotation.The shoe according to the invention is characterized in that the auxiliary wedging means are constituted by at least one cam rotatably mounted between the shoe and the liner and secured to a pivot passing through the shoe and provided on the outside with a means allowing its rotation training.

Selon une forme d'exécution appliquée à une chaussure à coque en matière synthétique et comprenant un bas de coque destiné à entourer le pied et le talon et muni, à l'arrière, d'une languette relativement souple s'éten­dant vers le haut, et une tige en deux parties, dont une partie postérieure est articulée sur le bas de coque, les cames sont montées sur la partie postérieure de la tige et agissent sur la languette du bas de coque.According to an embodiment applied to a shell shoe made of synthetic material and comprising a shell bottom intended to surround the foot and the heel and provided, at the rear, with a relatively flexible tongue extending upwards, and a rod in two parts, of which a rear part is articulated on the bottom of the shell, the cams are mounted on the rear part of the rod and act on the tongue of the bottom of the shell.

Les moyens d'entraînement sont constitués par exemple par une fente de vis permettant d'entraîner les cames en rotation au moyen d'une pièce de monnaie.The drive means consist for example of a screw slot making it possible to drive the cams in rotation by means of a coin.

La chaussure représentée est une chaussure à coque com­prenant un bas de coque 1 en matière synthétique rela­tivement rigide entourant le pied et le talon et une tige articulée sur ce bas de coque 1, tige comportant une partie antérieure 2 et une partie postérieure 3, ces deux parties étant articulées sur le bas de coque en deux points opposés dont l'un, 4, est visible sur le dessin. Ce type de chaussure, à chaussage par l'arriè­re, est bien connu en soi. La partie postérieure 3 de la tige est munie d'un rembourrage 5 coopérant avec un chausson intérieur 6 pour assurer le confort du pied. Comme ceci est mieux visible à la figure 2, le chausson 6 est muni à l'arrière d'une poche 7 dans laquelle s'engage une languette 8 relativement souple solidaire du bas de coque 1 par une partie rétrécie 9 permettant à la languette de fléchir vers l'avant et vers l'arriè­re et de prendre une courbure plus ou moins prononcée.The shoe represented is a shell shoe comprising a shell bottom 1 made of relatively rigid synthetic material surrounding the foot and the heel and a rod articulated on this shell bottom 1, rod comprising a front part 2 and a rear part 3, these two parts being articulated on the bottom of the shell at two opposite points, one of which, 4, is visible in the drawing. This type of shoe, with rear boot, is well known in itself. The rear part 3 of the upper is provided with padding 5 cooperating with an inner liner 6 to ensure the comfort of the foot. As this is better visible in Figure 2, the liner 6 is provided at the rear of a pocket 7 in which engages a relatively flexible tongue 8 secured to the bottom of the shell 1 by a narrowed portion 9 allowing the tongue to flex forward and backward and take a more or less pronounced curvature.

Sur la partie postérieure 3 de la tige, dans deux zones situées au-dessus du talon, de chaque côté de la chaus­sure et de part et d'autre de la partie de la tige des­tinée à venir en face du tendon d'Achille du skieur, sont disposées deux cames 10 dont l'une est visible sur le dessin. Les zones du pied concernées sont donc les zones délimitées par les malléoles, le talon et le ten­don d'Achille. Chaque came 10 est solidaire d'un pivot 11 traversant la paroi de la partie postérieure 3 de la tige et munie à l'extérieur d'une tête 12 présentant une fente de vis 13 pour son entraînement au moyen d'une pièce de monnaie ou d'un tournevis. La came 10 présente un bossage 14 s'étendant sur environ la moitié du disque 15 constituant la base de la came et centré sur l'axe du pivot 11. La came pourrait cependant avoir une forme différente. Elle pourrait par exemple avoir la forme d'une came cloche telle que connue en mécani­que. L'essentiel est que lors de la rotation de la came, celle-ci vienne repousser progressivement vers l'inté­rieur le côté de la languette 8 qui vient donc se re­fermer de chaque côté du tendon d'Achille. Il est ainsi possible de caler parfaitement le talon.On the rear part 3 of the upper, in two zones located above the heel, on each side of the boot and on either side of the part of the upper intended to come in front of the Achilles tendon of the skier , are arranged two cams 10, one of which is visible in the drawing. The areas of the foot concerned are therefore the areas delimited by the malleoli, the heel and the Achilles tendon. Each cam 10 is integral with a pivot 11 passing through the wall of the rear part 3 of the rod and provided on the outside with a head 12 having a screw slot 13 for its drive by means of a coin or a screwdriver. The cam 10 has a boss 14 extending over approximately half of the disc 15 constituting the base of the cam and centered on the axis of the pivot 11. The cam could however have a different shape. It could for example have the shape of a bell cam as known in mechanics. The main thing is that during the rotation of the cam, the latter gradually pushes inwards the side of the tongue 8 which therefore comes to close on each side of the Achilles tendon. It is thus possible to perfectly wedge the heel.

La faible pente circonférentielle de la came suffit en principe à empêcher que la réaction de la languette 8 sur la came entraîne cette dernière en rotation. Toute­fois, il est possible de prévoir un système de crantage pour maintenir la came dans la position choisie.The slight circumferential slope of the cam is sufficient in principle to prevent the reaction of the tongue 8 on the cam causing the latter to rotate. However, it is possible to provide a notching system to keep the cam in the chosen position.

L'invention a été décrite dans le cas d'une chaussure à chaussage par l'arrière, mais le système de cames dé­crit peut être monté sur tout type de chaussure à tige articulée ou non.The invention has been described in the case of a shoe with a rear boot, but the cam system described can be mounted on any type of shoe with an articulated rod or not.

Dans le cas d'une chaussure ne présentant pas la lan­guette 8, les cames pourraient agir directement sur le chausson ou sur le rembourrage solidaire de la partie arrière de la tige. Les cames pourraient être montées sur un bas de coque. Les cames pourraient être entraî­nées en rotation par tout autre moyen qu'une fente de vis.In the case of a shoe not having the tongue 8, the cams could act directly on the liner or on the padding integral with the rear part of the upper. The cams could be mounted on a bottom of the hull. The cams could be rotated by any means other than a screw slot.

Les cames peuvent être en métal ou en plastique dur. Une ou deux cames analogues aux cames décrites ci-des­sus pourraient être également utilisées pour caler l'avant-pied. Un exemple est représenté aux figures 4 et 5. La chaussure représentée est équipée de deux cames 16 et 17 montées sur la coque 1, de part et d'autre du plan vertical médian de cette coque. Les cames agissent sur une plaque flexible 18 montée entre la coque 1 et le chausson de confort 6, qui a pour fonction de répar­tir la pression des cames. Cette plaque 18 est consti­tuée soit par le prolongement d'un répartiteur de pres­sion recouvrant le cou-de-pied pour la répartition de la pression d'un câble, soit par une plaque particuliè­re qui peut être fixée par son extrémité dans la région du bout du pied. L'action des cames 16 et 17 permet non seulement de caler le pied dans la chaussure mais aussi de positionner l'axe du pied de façon optimale pour la conduite du ski.The cams can be made of metal or hard plastic. One or two cams similar to the cams described above could also be used to block the forefoot. An example is shown in Figures 4 and 5. The shoe shown is equipped with two cams 16 and 17 mounted on the shell 1, on either side of the median vertical plane of this shell. The cams act on a flexible plate 18 mounted between the shell 1 and the comfort liner 6, which has the function of distributing the pressure of the cams. This plate 18 is constituted either by the extension of a pressure distributor covering the instep for the distribution of the pressure of a cable, or by a particular plate which can be fixed by its end in the region of the end of the foot. The action of the cams 16 and 17 makes it possible not only to wedge the foot in the boot but also to position the axis of the foot optimally for driving the ski.
