Abstract

The boot, made from a plastic shell (1) and an inner lining, has at least one zone (12) of reduced rigidity on the inside or outside of the shell in line with the metatarso-phalangeal joint. The shell is made from two layers of plastic, e.g. polyurethane, with different degrees of rigidity, with the supple zone(s) (12) formed by the less rigid layer of plastic only, the hardness of which is between 45 and 55 shD. In variants the supple zone can include textile or elastomer materials, or it can be made from a hole in the plastic shell aligned with a patch of a less rigid plastic material on the liner.

Description

La présente invention concerne une chaussure de sport, en particulier de ski ou de patin, comportant une coque en matière plastique et un chausson intérieur, ladite coque présentant au moins une zone de rigidité inférieure à la rigidité du reste de la coque.The present invention relates to a sports shoe, in particular skiing or skating, comprising a hull made of plastic and an inner liner, said shell having at least one zone of rigidity less than the rigidity of the rest of the hull.

Depuis l'apparition sur le marché des chaussures de ski en matière plastique comprenant une coque relativement rigide assurant une bonne tenue du pied, il arrive fréquemment que les skieurs aux pieds larges ressentent une douleur au niveau de l'articulation métatarsophalangienne, du côté extérieur du pied, douleur due à une compression de cette zone par la coque de la chaussure. Pour remédier à cette douleur, des appareils spéciaux ont été développés pour dilater la coque par déformation dans la zone sensible. A ce jour encore, malgré la maítrise de la bi-injection et les développements présentés par les fabricants spécialisés, aucune solution pratique n'a été apportée à ce problème.Since the appearance on the ski boot market made of plastic comprising a shell relatively rigid ensuring good foot hold, it happens that wide-footed skiers often experience pain in the joint metatarsophalangeal, on the outside of the foot, pain due to compression of this area by the shoe shell. To remedy this pain, special devices have been developed to expand the shell by deformation in the sensitive area. At this day again, despite the mastery of bi-injection and the developments presented by the manufacturers specialized, no practical solution has been found to this problem.

Dans le brevet FR 2 077 184 il a certes été proposé, pour la première fois, de fabriquer, par bi-injection, une coque de chaussure de ski présentant divers degrés de souplesse dans diverses régions de l'empeigne, mais le problème susmentionné n'a pas été résolu de façon spécifique et satisfaisante. Cette coque présente une partie principale relativement souple sur laquelle sont formées des surépaisseurs en matière plus rigide et des zones d'accrochage relativement dures sont prévues en face de l'articulation métatarsophalangienne.In the patent FR 2 077 184 it was certainly proposed, for the first time, to manufacture, by bi-injection, a ski boot shell having varying degrees flexibility in various regions of the upper, but the aforementioned problem has not been resolved in a manner specific and satisfactory. This shell has a relatively flexible main part on which are formed by extra thicknesses of more rigid material and relatively hard attachment areas are provided in face of the metatarsophalangeal joint.

La technique de la bi-injection, c'est-à-dire d'injections successives dans le même moule, est également utilisée pour la fabrication de la chaussure décrite dans le brevet FR 2 671 947.The bi-injection technique, that is to say of successive injections in the same mold, is also used for shoe manufacturing described in patent FR 2,671,947.

Enfin, de la demande de brevet EP 0 645 101 et du Modèle International DM/037 399, on connaít une coque de chaussure de ski présentant des zones de rigidité différentes, les parties les plus rigides constituant une sorte d'armature rigide triangulée dont le rôle est une transmission optimale des efforts entre la jambe et la fixation. Cette armature s'étend dans la région métatarsophalangienne.Finally, from patent application EP 0 645 101 and from International DM / 037 399 model, we know a shell ski boot having areas of stiffness different, the more rigid parts constituting a kind of triangular rigid reinforcement whose role is optimal transmission of forces between the leg and fixation. This frame extends in the region metatarsophalangeal.

La présente invention a pour but d'apporter une solution simple au problème de la douleur ressentie au niveau de l'articulation métatarsophalangienne. En effet, si l'on considère la population des personnes qui ont une pointure donnée, la largeur de l'articulation métatarsophalangienne varie ainsi que sa position par rapport au talon.The present invention aims to provide a simple solution to the problem of pain felt in level of the metatarsophalangeal joint. In indeed if we consider the population of people who have a given size, the width of the metatarsophalangeal joint varies as well as its position relative to the heel.

La chaussure selon l'invention est caractérisée en ce que la zone de rigidité inférieure est une zone relativement souple située sur le côté de la coque correspondant au côté extérieur et/ou intérieur du pied, de manière à être en face de l'articulation métatarsophalangienne. The shoe according to the invention is characterized in that that the lower stiffness zone is an area relatively flexible located on the side of the hull corresponding to the exterior and / or interior side of the foot, so as to be in front of the joint metatarsophalangeal.

Cette zone peut être de dimensions réduites, mais sa souplesse doit être suffisante pour qu'elle puisse se déformer aisément latéralement sous la poussée de l'articulation métatarsophalangienne sans exercer une pression douloureuse sur cette zone.This area may be reduced in size, but its flexibility must be sufficient for it to easily deform laterally under the pressure of the metatarsophalangeal joint without exerting a painful pressure on this area.

Cette zone de rigidité inférieure est de préférence obtenue par l'injection, selon un procédé de bi-injection, d'un plastique souple dans ladite zone.This lower stiffness zone is preferably obtained by injection, according to a bi-injection process, flexible plastic in said area.

La coque peut bien entendu présenter d'autres zones de moindre rigidité.The shell can of course have other areas of less rigidity.

Le dessin annexé représente, à titre d'exemple, deux modes d'exécution de l'invention.The accompanying drawing shows, by way of example, two modes of carrying out the invention.

La figure 1 représente une chaussure de ski, vue du côté extérieur du pied.FIG. 1 represents a ski boot, seen from the outside of the foot.

La figure 2 est une vue en coupe transversale selon II-II de la figure 1, sans la boucle de fermeture et de serrage.Figure 2 is a cross-sectional view along II-II in Figure 1, without the closure loop and Tightening.

La figure 3 est une vue en coupe transversale selon II-II de la figure 1, sans la boucle de fermeture et de serrage représentant un deuxième mode d'exécution de l'invention.Figure 3 is a cross-sectional view along II-II in Figure 1, without the closure loop and tightening representing a second embodiment of the invention.

La chaussure de ski représentée à la figure 1 est constituée d'une coque 1, dite à volume variable, destinée à entourer le pied et la cheville et d'un collier 2 articulé sur la coque 1 en un point 3 situé dans la région malléolaire, ce collier 2 étant destiné à entourer le bas de la jambe. Cette chaussure, selon une construction bien connue, est munie de deux boucles de serrage 4 et 5 pour le serrage de la coque 1 et de deux boucles 6 et 7 pour le serrage du collier 2. On distingue en outre un chausson intérieur de confort 8.The ski boot shown in Figure 1 is consisting of a shell 1, called a variable volume, intended to surround the foot and ankle and with a collar 2 articulated on the shell 1 at a point 3 located in the malleolar region, this collar 2 being intended to surround the lower leg. This shoe, according to a well-known construction, has two loops clamp 4 and 5 for clamping the shell 1 and two loops 6 and 7 for tightening the collar 2. On further distinguishes an inner comfort shoe 8.

Comme on peut le voir à la figure 2, la coque 1 est constituée de deux couches de matière plastique la et 1b associées par un procédé de bi-injection, ou de multi-injection ou encore par collage ou par un autre procédé équivalent. Les matières plastiques utilisées sont de préférence du polyuréthanne. La couche la, située à l'intérieur de la coque est constituée d'un plastique présentant une élasticité sensiblement supérieure à l'élasticité de la partie extérieure lb qui inclus la semelle 9 et le rabat supérieur 10 de la coque qui est constitué uniquement du plastique le plus rigide.As can be seen in Figure 2, the shell 1 is consisting of two layers of plastic la and 1b associated by a bi-injection process, or multi-injection or by bonding or by another equivalent process. The plastics used are preferably polyurethane. The layer there, located inside the hull consists of a plastic with substantially elasticity greater than the elasticity of the external part lb which includes the sole 9 and the upper flap 10 of the shell which is made only of the most plastic rigid.

Sur le côté extérieur de la chaussure, la partie extérieure 1b de la coque présente une découpe 11 positionnée de manière à entourer une zone de la coque située en face de l'articulation métatarsophalangienne du pied. Cette découpe 11 délimite une zone 12 dans laquelle on ne rencontre que le plastique le moins rigide la. La souplesse du plastique la est telle que la zone 12 peut se déformer légèrement sous la pression de l'articulation métatarsophalangienne du pied de manière à réduire sensiblement la pression sur cette articulation et, par conséquent, à éviter l'apparition d'une douleur à cet endroit. On the outside of the shoe, the part outer 1b of the shell has a cutout 11 positioned to surround an area of the hull located in front of the metatarsophalangeal joint of the foot. This cut 11 delimits an area 12 in which one encounters only the least plastic rigid the. The flexibility of the plastic is such that zone 12 can deform slightly under pressure of the metatarsophalangeal joint of the foot of so as to significantly reduce the pressure on this joint and, therefore, to avoid the appearance of pain there.

Le plastique de la couche 1b présente une dureté comprise entre 58 et 68 shD par exemple 62 shD, tandis que la couche la présente une dureté comprise entre 45 shD et 55 shD par exemple 54 shD.Layer 1b plastic has hardness between 58 and 68 shD for example 62 shD, while that the layer has a hardness of between 45 shD and 55 shD for example 54 shD.

L'étendue de la zone 12 pourra varier dans une certaine mesure, cette étendue ne devant toutefois pas être trop grande pour ne pas affecter la rigidité générale de l'extrémité avant de la coque.The extent of zone 12 may vary within a certain extent, this extent should not however be too great not to affect the general stiffness of the front end of the hull.

Bien que la coque a été représentée uniquement avec la découpe 11, elle pourrait présenter d'autres zones du même type dans le but d'alléger la coque comme prévu dans l'art antérieur.Although the hull has been shown only with the cutout 11, it could have other areas of the same type in order to lighten the hull as expected in the prior art.

Dans un deuxième mode d'exécution de l'invention, la coque 1 est constituée d'une seule couche de matière plastique et elle comporte une découpe 11 similaire à celle du premier mode d'exécution décrit ci-dessus. Cette découpe délimite une zone dans laquelle on rencontre un élément en plastique 13 moins rigide que le reste de la coque, ledit élément 13 étant fixé au chausson de confort 8 lui-même et non à la coque 1, comme dans le premier mode d'exécution. La souplesse de cet élément 13 en plastique moins rigide permet également une légère déformation sous la pression de l'articulation métatarsophalangienne. De plus, l'étanchéité de la coque 1 est assurée lors du serrage de la chaussure sur le pied. In a second embodiment of the invention, the shell 1 consists of a single layer of material plastic and it has a cutout 11 similar to that of the first embodiment described above. This cutout delimits an area in which meets a plastic element 13 less rigid than the rest of the hull, said element 13 being fixed to the comfort liner 8 itself and not the shell 1, as in the first embodiment. The flexibility of this less rigid plastic element 13 allows also a slight deformation under the pressure of the metatarsophalangeal joint. Moreover, the tightness of the shell 1 is ensured during tightening of the shoe on the foot.

Différents types d'empilage des matériaux souples et rigides peuvent être envisagés, en particulier le matériau souple ne pourrait être prévu que dans la zone 12. Par exemple, la matière souple pourrait se trouver dans la continuation de la matière rigide, voire même à l'extérieur de celle-ci.Different types of stacking of flexible materials and rigid can be considered, especially the flexible material could only be provided in the area 12. For example, the flexible material could be in the continuation of the rigid material, even to outside of it.

On pourrait également prévoir dans la zone 12 d'autres matériaux tels que des matériaux textiles ou des élastomères.We could also foresee in zone 12 other materials such as textile materials or elastomers.

De plus, l'élément 13 en plastique moins rigide peut entourer, au moins partiellement, le chausson intérieur 8.In addition, the element 13 made of less rigid plastic can surround, at least partially, the inner liner 8.

Les modes d'exécution décrits le sont à titre d'exemple, et l'application de l'invention n'est pas limitée aux chaussures de ski: le principe de l'invention peut très bien s'appliquer à d'autres chaussures, comme par exemple des chaussures de patins, comportant une coque relativement rigide qui crée des problèmes similaires à ceux des chaussures de ski.The modes of execution described are for example, and the application of the invention is not limited to ski boots: the principle of the invention can very well be applied to other shoes, such as skate shoes, with a relatively rigid shell which creates problems similar to those of ski boots.
