Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des chaussures de sport, notamment le domaine des chaussures de sport comportant une coque rigide pour le ski, le patin, etc. La présente invention concerne en particulier une chaussure de sport avec une coque rigide exogène et une chaussure interne amovible de type randonnée.The present invention relates to the field of sports shoes, including the field of sports shoes with a rigid shell for skiing, skate, etc. The present invention particularly relates to a sports shoe with an exogenous rigid shell and a removable inner boot hiking type.

Etat de la techniqueState of the art

On connait dans l'état de la technique des chaussures de ski comportant une chaussure interne et une coque exogène rigide. La chaussure interne peut être extraite de la coque exogène pour marcher plus confortablement, ou insérée dans cette coque pour skier. Un exemple d'une telle chaussure est décrit dans WO2009/097550 .Ski shoes having an internal shoe and a rigid exogenous shell are known in the state of the art. The inner shoe can be extracted from the exogenous shell to walk more comfortably, or inserted into this hull to ski. An example of such a shoe is described in WO2009 / 097550 .

Bref résumé de l'inventionBrief summary of the invention

Un des problèmes avec les chaussures de ski à coque exogène est la transmission des forces entre la chaussure interne et la coque exogène. En effet la chaussure interne n'est en général pas fixée à la coque exogène, mais peut coulisser ou bouger à l'intérieur, ce qui empêche une transmission des forces efficace et nuit au style de ski.One of the problems with exogenous hull ski boots is the transmission of forces between the inner shoe and the exogenous hull. Indeed the internal shoe is generally not attached to the exogenous shell, but can slide or move inside, which prevents an effective transmission of forces and harms the ski style.

Un but de la présente invention est de proposer une nouvelle chaussure de sport à coque exogène améliorée.An object of the present invention is to provide a new improved exogenous hull sports shoe.

Selon l'invention, ces buts sont atteints notamment au moyen d'une chaussure de sport comportant :

  • une chaussure interne ;
  • une coque exogène dont les dimensions permettent d'y insérer ou d'extraire la dite chaussure interne, ladite coque exogène permettant de renforcer ladite chaussure interne et de la fixer sur un article de sport;
  • ladite coque exogène comportant une semelle et une tige ; la face interne de cette semelle comportant un motif en relief, par exemple des nervures et des rainures, coopérant avec un motif correspondant sous la semelle de la chaussure interne, de manière à positionner latéralement et en hauteur la chaussure interne dans la coque exogène.
According to the invention, these goals are achieved in particular by means of a sports shoe comprising:
  • an internal shoe;
  • an exogenous shell whose dimensions allow to insert or extract said internal shoe, said exogenous shell for reinforcing said inner shoe and fix it on a sports article;
  • said exogenous shell having a sole and a stem; the inner face of this sole having a pattern in relief, for example ribs and grooves, cooperating with a corresponding pattern under the sole of the inner shoe, so as to position laterally and height the inner shoe in the exogenous shell.

Cette construction fournit donc un point de fixation rigide (au moins selon l'axe perpendiculaire au pied) entre la chaussure interne et la coque exogène.This construction therefore provides a rigid attachment point (at least along the axis perpendicular to the foot) between the inner shoe and the exogenous shell.

Dans un mode de réalisation, la chaussure interne comporte un pivot protubérant sur la face externe près de la cheville,
ladite coque exogène comportant un logement pour loger le pivot.In one embodiment, the inner shoe has a protruding pivot on the outer face near the ankle,
said exogenous shell having a housing for housing the pivot.

Cette solution permet notamment de solidariser la chaussure interne et la coque exogène en un point important pour la transmission des forces notamment lors de virages à ski.This solution allows in particular to secure the inner shoe and exogenous shell at an important point for the transmission of forces especially during ski turns.

La coque exogène peut comporter une partie avant de tige apte à pivoter par rapport à la semelle autour d'une première articulation, et/ou une partie arrière de tige apte à pivoter par rapport à ladite semelle autour d'une deuxième articulation. La chaussure interne peut être insérée dans la coque exogène respectivement extraite de la coque exogène en faisant pivoter la partie arrière de la tige. Des boucles peuvent être prévues pour maintenir la partie avant de tige et la partie arrière de tige fermées et serrées l'une contre l'autre. Cette construction permet une extraction respectivement une insertion aisée de la chaussure interne, et un maintien efficace de cette chaussure interne au niveau de la cheville.The exogenous shell may comprise a stem front portion adapted to pivot relative to the sole around a first joint, and / or a rear portion of rod pivotable relative to said sole around a second joint. The inner shoe may be inserted into the exogenous shell respectively extracted from the exogenous shell by pivoting the rear portion of the shaft. Buckles may be provided to keep the stem front portion and the rod back portion closed and tightened against each other. This construction allows easy extraction or insertion of the inner shoe, and effective maintenance of the inner shoe at the ankle.

Le logement pour le pivot peut être ouvert respectivement fermé en faisant pivoter la partie avant de la tige et/ou la partie arrière de la tige. Une portion de la circonférence du logement peut être formée par une échancrure sur la partie avant la tige, et une autre portion de la circonférence de ce logement peut être formée par une échancrure sur la partie arrière de la tige. Le pivot protubérant sur la chaussure interne peut comporter une gorge annulaire pour y loger les échancrures. Cette construction permet une liaison rigide entre le pivot et le logement, et une désolidarisation facile de ces composants, simplement en ouvrant la partie avant ou arrière de la tige.The housing for the pivot can be opened respectively closed by pivoting the front part of the rod and / or the rear part of the rod. A portion of the circumference of the housing may be formed by a notch on the front portion of the shaft, and another portion of the circumference of this housing may be formed by a notch on the back part of the stem. The protruding pivot on the inner shoe may include an annular groove to accommodate the notches. This construction allows a rigid connection between the pivot and the housing, and easy disconnection of these components, simply by opening the front or rear of the rod.

La chaussure peut comporter un renfort achillaire articulé par rapport à la semelle de la coque exogène et pouvant être fixé à la tige arrière.The shoe may comprise an achillar reinforcement hinged to the sole of the exogenous shell and can be attached to the rear rod.

Selon une caractéristique indépendante de la présence d'un pivot et d'un logement, la semelle de la coque exogène peut comporter des trous pour l'évacuation de l'eau à l'intérieur de cette coque. Avantageusement, la coque exogène comporte une structure largement ajourée permettant de voir la chaussure interne et d'évacuer l'eau.According to an independent characteristic of the presence of a pivot and a housing, the sole of the exogenous shell may comprise holes for the evacuation of water inside this shell. Advantageously, the exogenous shell has a largely open structure allowing to see the inner shoe and evacuate the water.

L'invention concerne aussi une coque exogène telle que décrite.The invention also relates to an exogenous shell as described.

Exemple(s) de mode de réalisation de l'inventionExample (s) of embodiment of the invention

La chaussure de sport illustrée est une chaussure de ski. L'invention pourrait aussi s'appliquer à d'autres types de chaussures de sport, par exemple à des patins, à des chaussures de snow-board, etc.The illustrated sports shoe is a ski boot. The invention could also be applied to other types of sports shoes, for example skates, snowboard boots, etc.

La chaussure de sport illustrée sur la figure 1 comporte une chaussure interne 3, illustrée plus en détail sur la figure 5, et une coque exogène 1 illustrée sur les figures 2 à 4. La chaussure interne 3 est destinée à tenir le pied au chaud, et à permettre une marche confortable en ville, au restaurant de ski ou dans la neige. La coque exogène 1 est destinée à rigidifier cette chaussure interne et à permettre de l'introduire dans une fixation de ski ou dans un autre article de sport. Le pied et la cheville sont maintenus par la chaussure interne, qui dispose par exemple de lacets, et avec une pression plus importante par la coque exogène lorsque celle-ci est fermée.The sports shoe illustrated on the figure 1 has an internal shoe 3, illustrated in more detail on the figure 5 , and an exogenous shell 1 illustrated on Figures 2 to 4 . The internal shoe 3 is designed to keep the foot warm, and allow a comfortable walk in the city, at the ski restaurant or in the snow. The exogenous shell 1 is intended to stiffen this internal shoe and allow to introduce it into a ski binding or other sporting article. The foot and ankle are held by the inner shoe, which has for example laces, and with greater pressure by the exogenous shell when it is closed.

La chaussure interne 3 comporte différents matériaux de rembourrage mous 35 assurant l'isolation thermique, l'imperméabilité et garantissant le confort. La semelle de la chaussure interne et des arceaux de renfort par-dessus la base et/ou la tige peuvent cependant être réalisés dans des matériaux synthétiques rigides. La chaussure interne n'est cependant pas entièrement protégée par la coque exogène 1 et doit donc être réalisée dans des matériaux étanches. Par exemple, la chaussure interne peut être réalisée en cuir, en goretex, en nylon etc, avec des rembourrages mous en matériaux synthétiques ou naturels.The inner shoe 3 has various soft cushioning materials 35 providing thermal insulation, impermeability and guaranteeing comfort. The sole of the inner shoe and reinforcement arches over the base and / or the upper may, however, be made of rigid synthetic materials. The inner shoe is however not fully protected by the exogenous shell 1 and must therefore be made of waterproof materials. For example, the inner shoe can be made of leather, goretex, nylon etc., with soft padding of synthetic or natural materials.

La coque externe 1 est de son côté réalisée en matériau synthétique rigide. Sa structure est largement ajourée afin de l'alléger et de voir la chaussure interne.The outer shell 1 is in turn made of rigid synthetic material. Its structure is widely openwork to lighten and see the internal shoe.

Les dimensions de la coque exogène permettent d'y insérer ou d'extraire la chaussure interne. Comme on le voit sur la figure 2, elle comporte une semelle 10, une partie avant de tige 11 apte à pivoter par rapport à la semelle 10 autour d'une première articulation 110, et une partie arrière de tige 12 qui peut pivoter par rapport à la semelle 10 autour d'une deuxième articulation 120.Dans une variante non illustrée, il est aussi possible de n'avoir qu'une des deux parties de tige qui soit articulée. La chaussure interne peut être insérée dans la coque exogène, respectivement extraite de cette coque, en faisant pivoter la partie avant de la tige 11 et/ou la partie arrière de la tige 12, comme on le voit sur les figures 3 et 4. Dans un mode de réalisation, la chaussure interne pourrait cependant être extraite ou insérée en pivotant seulement la partie arrière 12, la partie avant restant dans la position illustrée sur la figure 3 ; le pivotement de la partie avant rend cependant l'extraction plus facile, et permet en outre de réduire la hauteur et l'encombrement de l'exosquelette s'il reste sur le ski. La référence 18 illustre un renfort achillaire pivotant autour d'un axe 180 lié à la base de la coque exogène, et qui se fixe en position fermée contre la face interne de la tige arrière 12 au moyen d'un tenon 182 inséré dans une ouverture dans cette tige arrière.The dimensions of the exogenous shell allow to insert or extract the inner shoe. As we see on the figure 2 it comprises a soleplate 10, a stem front portion 11 pivotable relative to the sole 10 around a first hinge 110, and a rear portion of the rod 12 which is pivotable relative to the soleplate 10 around a second articulation 120. In a variant not shown, it is also possible to have only one of the two rod parts that is articulated. The inner shoe can be inserted into the exogenous shell, respectively extracted from this shell, by pivoting the front part of the rod 11 and / or the rear part of the rod 12, as seen on the figures 3 and 4 . In one embodiment, however, the inner shoe could be extracted or inserted by pivoting only the rear portion 12, with the front portion remaining in the position shown in FIG. figure 3 ; the pivoting of the front part however makes the extraction easier, and also reduces the height and bulk of the exoskeleton if it remains on the ski. The reference 18 illustrates an achillary reinforcement pivoting about an axis 180 connected to the base of the exogenous shell, and which is fixed in closed position against the inner face of the rear rod 12 by means of a pin 182 inserted in an opening in this back rod.

La coque exogène 1 peut être fermée et serrée au moyen de boucles de chaussures, dans cet exemple deux boucles 112 113 qui permettent de tendre des câbles maintenant la tige avant 11 serrée contre la tige arrière 12.The exogenous shell 1 can be closed and tightened by means of shoe loops, in this example two loops 112 113 which allow tensioning of the cables holding the front rod 11 tight against the rear rod 12.

La chaussure interne illustrée sur la figure 5 comporte une base 31, une tige 30 et une semelle 37. La référence 35 indique les rembourrages. Elle se ferme au moyen d'un lacet 36 avec un arrêt de lacet 34 qui permet de tendre le lacet et d'accrocher l'arrêt 34 à un point fixe sur la langue 33.The internal shoe illustrated on the figure 5 comprises a base 31, a rod 30 and a sole 37. The reference 35 indicates the padding. It closes by means of a lace 36 with a lace stop 34 which makes it possible to tension the lace and to hook the stop 34 at a fixed point on the tongue 33.

La chaussure interne 3 comporte en outre un pivot 300 sur la face externe de la cheville, qui permet de la fixer à la coque exogène. Un pivot similaire pourrait aussi être prévu sur la face interne de la cheville, mais s'avère à l'usage gênant pour la marche, en sorte que pour beaucoup de types de chaussure il est préférable d'y renoncer.The inner shoe 3 further comprises a pivot 300 on the outer face of the ankle, which allows to fix it to the exogenous shell. A similar pivot could also be provided on the inner side of the ankle, but is inconvenient for walking, so that for many types of shoe it is better to give up.

La coque exogène comporte un logement 14 sur la face interne de la cheville afin de loger ce pivot. Lelogementest constitué par une échancrure 140 en demi-cercle sur la tige avant 11, et une échancrure 141 similaire sur la tige arrière 12, qui viennent se glisser dans une gorge 301 dans le pivot 300. Le logement 14 peutdonc être ouvert respectivement fermé en faisant pivoter la partie avant de la tige 11 et/ou la partie arrière de la tige 12 de la coque exogène.Le pivot 300 constitue donc un point de fixation rigide entre la chaussure interne 3 et la coque exogène 1, permettant de transmettre les forces de manière efficace entre ces deux parties de la chaussure.The exogenous shell has a housing 14 on the inner face of the ankle to accommodate this pivot. The housing consists of a notch 140 in a semicircle on the front rod 11, and a notch 141 similar to the rear rod 12, which are slid into a groove 301 in the pivot 300. The housing 14 can be open respectively closed by making pivoting the front portion of the rod 11 and / or the rear portion of the rod 12 of the exogenous shell.The pivot 300 is therefore a rigid attachment point between the inner shoe 3 and the exogenous shell 1, for transmitting the forces of effective way between these two parts of the shoe.

Dans une variante non illustrée, la base 31 de la chaussure interne est articulée par rapport à la tige 30 de cette chaussure interne autour des deux pivots, de manière à permettre une flexion limitée de la tige.In a variant not shown, the base 31 of the inner shoe is articulated relative to the stem 30 of the inner shoe around the two pivots, so as to allow limited flexion of the rod.

Les figures 8 et 9 illustrent deux vues de la semelle 10 de la coque exogène 1. Comme on le voit sur la figure 8, la semelle 10 comporte une plaquette avant 102 et une plaquette arrière 103 qui constituent des pièces d'usures remplaçables fixées sous la semelle. Des trous 100 à travers la semelle 10 permettant à l'eau et à la neige qui s'accumule à l'intérieur de la coque exogène de s'évacuer.The Figures 8 and 9 illustrate two views of the sole 10 of the exogenous shell 1. As seen in the figure 8 , the soleplate 10 comprises a front plate 102 and a rear plate 103 which constitute replaceable wear parts fixed under the soleplate. Holes 100 through the sole 10 allowing the water and snow accumulating inside the exogenous hull to escape.

La face interne de la semelle 10 est munie d'un motif en relief, constitué ici par des nervures 101 séparées par des rainures et collaborant avec des rainures et des nervures correspondantes sous la semelle 37 de la chaussure interne, afin de garantir un positionnement latéral précis de la chaussure interne 3 dans la coque exogène 1, et une transmission des forces entre ces deux parties de la chaussure. Cette construction permet en outre de garantir un positionnement constant de la chaussure interne dans la coque exogène, même si la semelle 37 s'use suite à la marche ; en effet le fond des rainures sous la semelle 37 est peu susceptible de s'user, en sorte que la position verticale de la chaussure interne reste inchangée même si les nervures de la semelle 37 s'usent.The inner face of the sole 10 is provided with a relief pattern, constituted here by ribs 101 separated by grooves and collaborating with grooves and corresponding ribs under the sole 37 of the inner shoe, to ensure accurate lateral positioning of the inner shoe 3 in the exogenous shell 1, and a transmission of forces between these two parts of the shoe. This construction also ensures a constant positioning of the inner shoe in the exogenous shell, even if the sole 37 wears out after walking; indeed the bottom of the grooves under the sole 37 is unlikely to wear, so that the vertical position of the inner shoe remains unchanged even if the ribs of the sole 37 wear out.

La coque exogène comporte avantageusement une structure largement ajourée permettant de voir la chaussure interne. Dans un mode de réalisation, la semelle de la coque exogène est composée de deux parties soudées, collées ou assemblées mécaniquement l'une à l'autre; en variant la position longitudinale de fixation, on peut produire des semelles de différentes pointures à partir d'un seul moule.The exogenous shell advantageously has a widely open structure allowing to see the inner shoe. In one embodiment, the sole of the exogenous shell is composed of two parts welded, glued or mechanically joined to each other; by varying the longitudinal position of fixation, it is possible to produce soles of different sizes from a single mold.
