Description

L'invention concerne une coque d'une chaussure de sport pour planche de glisse ainsi que la chaussure de sport elle-même, et est particulièrement adaptée au domaine des chaussures pour planches de glisse telles que ski ou surf, qui subissent des efforts importants lors de leur utilisation au niveau de zones de contact avec un dispositif de fixation de la planche de glisse. Enfin, l'invention concerne aussi un procédé de fabrication d'une telle coque et chaussure de sport.The invention relates to a shell of a sports shoe for gliding board and the sports shoe itself, and is particularly suitable for the field of shoes for boards of gliding such as ski or surf, which undergo significant efforts during their use at contact areas with a device for fixing the gliding board. Finally, the invention also relates to a method of manufacturing such a shell and sports shoe.

Une chaussure de ski est un bon exemple de chaussure de sport qui subit de nombreux efforts et doit être dotée d'une bonne rigidité et dureté superficielle, notamment au niveau de ses trottoirs avant et arrière qui coopèrent avec des mâchoires rigides d'un dispositif de fixation positionné sur le ski. Toutefois, elle doit aussi posséder une souplesse suffisante pour assurer un confort au skieur et lui permettre d'ouvrir la chaussure pour la chausser et l'enlever et lui permettre de fléchir ses genoux vers l'avant.A ski boot is a good example of a sports shoe that is undergoing a lot of effort and must have a good rigidity and superficial hardness, especially at its front and rear sidewalks that cooperate with rigid jaws of a device. fixing positioned on the ski. However, it must also have sufficient flexibility to provide comfort to the skier and allow him to open the shoe for the shoe and remove it and allow him to bend his knees forward.

Pour répondre à ces contraintes élevées et contradictoires, une des solutions les plus répandues consiste en la réalisation d'une chaussure de ski se composant d'une tige rigide bi-injectée dans laquelle est inséré un chausson de confort. La tige rigide se compose d'une coque entourant le pied et d'un collier articulé sur cette coque et entourant le bas de la jambe. Cette tige est en matériau rigide, réalisée par un procédé de bi-injection de deux matériaux plastiques de rigidité différente dont la quantité de chacun de ces matériaux est prévue sur chaque zone de la tige pour répondre au compromis entre les exigences de rigidité et dureté et celle de confort. Le matériau le plus rigide et dur se retrouve notamment au sein des trottoirs, donc dans les zones de coopération avec le dispositif de fixation sur le ski.In order to meet these high and contradictory constraints, one of the most widespread solutions consists in producing a ski boot consisting of a rigid bi-injected rod in which a comfort boot is inserted. The rigid stem consists of a hull surrounding the foot and a hinged collar on the hull and surrounding the bottom of the leg. This rod is made of rigid material, made by a process of bi-injection of two plastic materials of different rigidity, the amount of each of these materials is provided on each zone of the rod to meet the compromise between the requirements of stiffness and hardness and that of comfort. The most rigid and hard material is found in particular within the sidewalks, so in areas of cooperation with the fixture on the ski.

Ces chaussures conventionnelles présentent les inconvénients suivants :

  • la fabrication de la tige nécessite des moulages complexes et coûteux pour mettre en oeuvre la double injection de matériaux plastiques ;
  • même un matériau plastique de grande dureté présente des propriétés mécaniques insuffisantes et subit une usure rapide dans les zones de liaison avec les mâchoires des dispositifs de fixation sur les skis ;
  • la tige présente une esthétique limitée, qui se dégrade vite du fait de l'usure de surface mentionnée au point précédent.
These conventional shoes have the following drawbacks:
  • the manufacture of the rod requires complex and expensive moldings to implement the double injection of plastic materials;
  • even a plastic material of high hardness has insufficient mechanical properties and undergoes rapid wear in the connection areas with the jaws of the fasteners on the skis;
  • the stem has a limited aesthetic, which degrades quickly due to the surface wear mentioned in the previous point.

Le document EP0582553 décrit une autre solution qui consiste en l'ajout d'un renfort consistant en l'ajout d'une pièce métallique fixée par une liaison mécanique de type rivets ou équivalent au reste de la structure de la chaussure en matériau plastique. Ce procédé est complexe car il repose sur la modification profonde de la structure de la tige rigide de la chaussure, la paroi de la chaussure consistant sur certaines zones en la combinaison d'un matériau plastique avec ce renfort métallique. Le procédé de fabrication nécessite l'usinage séparé de la pièce métallique puis son assemblage avec la tige plastique moulée séparément et représentant une tige incomplète. Il n'est pas possible de réaliser sans surcoût inacceptable des formes complexes de renfort métallique avec ce procédé et seule la surface supérieure horizontale du trottoir comporte ce renfort. D'autres surfaces avoisinantes en contact avec des dispositifs de fixation de ski restent en matériau plastique et subissent l'usure rapide comme dans les solutions bi-injectées mentionnées au paragraphe précédent. Ainsi, cette solution permet d'offrir des chaussures de structure plus rigide, mais ne répond pas de manière satisfaisante aux usures de surface provoquées par la liaison avec les dispositifs de fixation. De plus, elle présente l'inconvénient supplémentaire d'alourdir significativement le poids de la chaussure.The document EP0582553 discloses another solution which consists of adding a reinforcement consisting of the addition of a metal part fixed by a mechanical connection type rivets or equivalent to the rest of the structure of the plastic shoe. This method is complex because it is based on the deep modification of the structure of the rigid upper of the shoe, the wall of the shoe consisting of certain areas in the combination of a plastic material with this metal reinforcement. The manufacturing process requires the separate machining of the metal part and its assembly with the plastic rod molded separately and representing an incomplete rod. It is not possible to achieve complex shapes of metal reinforcement with this method without unacceptable overcost and only the horizontal top surface of the sidewalk includes this reinforcement. Other neighboring surfaces in contact with ski binding devices remain in plastic material and undergo rapid wear as in the bi-injected solutions mentioned in the previous paragraph. Thus, this solution allows to offer structural shoes more rigid, but does not respond satisfactorily to the surface wear caused by the connection with the fasteners. In addition, it has the additional disadvantage of significantly increasing the weight of the shoe.

Le document FR2198360 décrit une autre solution alternative dans laquelle une partie importante de la coque est réalisée intégralement en métal. Cette solution a vite été abandonnée car elle présente les inconvénients d'une chaussure trop rigide et peu confortable, très coûteuse et lourde du fait de la quantité importante de métal utilisée, et enfin aux mauvaises propriétés thermiques, le métal conduisant rapidement le froid vers l'intérieur de la chaussure.The document FR2198360 describes another alternative solution in which a large part of the shell is made entirely of metal. This solution was quickly abandoned because it has the drawbacks of a shoe that is too rigid and uncomfortable, very expensive and heavy because of the large amount of metal used, and finally the poor thermal properties, the metal quickly leading the cold to the surface. inside the shoe.

Un objet de la présente invention consiste à proposer une coque de chaussure de sport ne présentant pas les inconvénients précédents.An object of the present invention is to provide a sports shoe shell does not have the above disadvantages.

Plus précisément, un premier objet de la présente invention consiste à proposer une coque de chaussure de sport qui permette d'atteindre une bonne résistance à l'usure au niveau de ses surfaces de liaison avec un dispositif de fixation sur une planche de glisse, en conservant une structure simple, un poids minimal, et avec une esthétique attrayante.More specifically, a first object of the present invention is to provide a sports boot shell that achieves good wear resistance at its connecting surfaces with a fastening device on a gliding board, in retaining a simple structure, minimal weight, and with an attractive aesthetic.

Un second objet de la présente invention consiste à proposer un procédé de fabrication simple et peu coûteux pour coque de chaussure de sport.A second object of the present invention is to provide a simple and inexpensive manufacturing method for sports shoe shell.

Le concept de l'invention est avantageux en ce qu'il ne modifie pas la structure de la coque de la chaussure de sport, mais ajoute une couche de surface métallique au moins sur ses surfaces de liaison, comme les trottoirs d'une chaussure de ski, la couche métallique étant obtenue par un procédé de métallisation. Cette approche est une alternative plus simple, plus efficace et moins coûteuse que les solutions basées sur l'intégration de renforts dans la structure de la chaussure. Elle reste compatible avec toutes les chaussures existantes, notamment avec les chaussures les plus simples obtenues par une bi-injection ou une seule injection de matériau plastique.The concept of the invention is advantageous in that it does not modify the structure of the shell of the sports shoe, but adds a layer of metal surface at least on its connecting surfaces, such as the sidewalks of a shoe. ski, the metal layer being obtained by a metallization process. This approach is a simpler alternative, more efficient and less expensive than the solutions based on the integration of reinforcements in the structure of the shoe. It remains compatible with all existing shoes, especially with the most simple shoes obtained by a bi-injection or a single injection of plastic material.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode d'exécution particulier fait à titre non-limitatif en relation avec les figures jointes parmi lesquelles :

  • La figure 1 représente une vue en perspective de côté d'une chaussure de ski selon l'invention ;
  • la figure 2 représente un agrandissement du trottoir avant de la chaussure de la figure 1 selon le mode d'exécution de l'invention ;
  • la figure 3 représente une vue en perspective simplifiée d'une chaussure de surf des neiges selon un mode d'exécution de l'invention.
These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:
  • The figure 1 represents a side perspective view of a ski boot according to the invention;
  • the figure 2 represents an enlargement of the front sidewalk of the shoe of the figure 1 according to the embodiment of the invention;
  • the figure 3 represents a simplified perspective view of a snowboard boot according to an embodiment of the invention.

Les figures 1 et 2 illustrent à titre d'exemple une chaussure de ski 1, comprenant un collier 7 articulé sur une coque 2 autour d'un axe 8, l'ensemble recevant un chausson de confort 9. La coque 2 est dans un matériau plastique habituel comme un polyuréthane de dureté 55 shd par exemple. Elle comprend des trottoirs avant 4 et arrière 3 normalisés, destinés à coopérer avec un dispositif de fixation de ski. Selon le concept de l'invention, les trottoirs 3, 4 sont recouverts par une couche métallique protectrice, de faible épaisseur de l'ordre de quelques micromètres, qui remplit une fonction de protection de la chaussure contre les usures provoquées par la coopération avec le dispositif de fixation en augmentant la dureté superficielle de la zone considérée. Cette zone correspond donc aux trottoirs normalisés. Elle s'étend avantageusement au moins sur les surfaces horizontales 10 des trottoirs qui reçoivent les mâchoires d'un dispositif de fixation. D'autre part, il est aussi avantageux d'étendre la couche de surface métallique sur la paroi verticale 11 des trottoirs au-dessus de la zone horizontale 10 précédente, pour résister à l'usure provoquée par les contacts avec les mâchoires des dispositifs de fixation du type « à prise sur tige », ainsi que sur la surface verticale 12 des trottoirs au-dessous de la zone horizontale 10 précédente, pour résister à l'usure provoquée par les contacts avec les mâchoires des dispositifs de fixation du type « à prise sur semelle », comme cela est illustré sur les figures.The figures 1 and 2 illustrate by way of example a ski boot 1, comprising a collar 7 articulated on a shell 2 around an axis 8, the assembly receiving a comfort liner 9. The shell 2 is made of a usual plastic material such as a polyurethane of hardness 55 shd for example. It comprises standardized front 4 and rear 3 sidewalks intended to cooperate with a ski binding device. According to the concept of the invention, the sidewalks 3, 4 are covered by a protective metal layer, of a small thickness of the order of a few microns, which fulfills a protective function of the shoe against the wear caused by the cooperation with the fixing device by increasing the surface hardness of the area. This zone corresponds to standard sidewalks. It advantageously extends at least on the horizontal surfaces of the sidewalks which receive the jaws of a fixing device. On the other hand, it is also advantageous to extend the metal surface layer on the vertical wall 11 of the sidewalks above the previous horizontal zone to resist the wear caused by the contacts with the jaws of the and the vertical surface 12 of the sidewalks below the previous horizontal zone to resist the wear caused by the jaw contacts of the fasteners of the type "to on the sole "as illustrated in the figures.

L'invention porte aussi sur le procédé de fabrication d'une telle coque de chaussure de ski, qui comprend une étape de métallisation d'au moins un trottoir de la coque de la chaussure. La coque peut être obtenue par une ou plusieurs étapes d'injection de matériau plastique. Ce procédé de métallisation peut consister en une métallisation sous vide ou une métallisation par électrolyse, connues de l'art antérieur.The invention also relates to the method of manufacturing such a ski boot shell, which comprises a step of metallization of at least one sidewalk of the shell of the shoe. The shell can be obtained by one or more plastic material injection steps. This metallization process may consist of vacuum metallization or metallization by electrolysis, known from the prior art.

Le matériau métallique utilisé peut par exemple comprendre de l'aluminium, de l'argent, du cuivre, du nickel ou du chrome. Le procédé de métallisation utilisé permet d'obtenir une couche métallique physiquement liée à la paroi plastique de la chaussure sur toute sa surface, par un accrochage mécanique ou chimique par exemple, ce qui participe à sa propriété d'augmentation importante de la dureté de la surface de la chaussure. La couche obtenue présente une faible épaisseur, généralement comprise entre quelques nanomètres et quelques micromètres, en tous cas inférieure à quelques centièmes de millimètres. Cette solution de surface de chaussure métallisée permet donc d'augmenter significativement la dureté de la paroi d'une chaussure qui conserve par ailleurs ses autres propriétés sensiblement inchangées en terme notamment de structure mécanique, rigidité, poids, épaisseur.The metallic material used may for example comprise aluminum, silver, copper, nickel or chromium. The metallization process used makes it possible to obtain a metal layer physically bonded to the plastic wall of the boot over its entire surface, for example by mechanical or chemical bonding, which contributes to its property of significantly increasing the hardness of the shoe. shoe surface. The layer obtained has a small thickness, generally between a few nanometers and a few micrometers, in any case less than a few hundredths of a millimeter. This metallized shoe surface solution therefore allows to significantly increase the hardness of the wall of a shoe which also retains its other substantially unchanged properties in terms in particular of mechanical structure, rigidity, weight, thickness.

Cette solution est compatible avec toutes les chaussures de l'art antérieur et peut être notamment combinée avec les chaussures incluant des renforts, dans la structure des trottoirs par exemple. Il est bien sûr possible d'appliquer avantageusement ce procédé de métallisation à uniquement un seul trottoir, ou à toute autre zone de la chaussure pour laquelle une plus grande dureté serait souhaitée, comme les zones des chaussures de compétition pouvant subir des usures par les chocs avec des piquets de slalom par exemple.This solution is compatible with all the shoes of the prior art and can be especially combined with shoes including reinforcements, in the structure of sidewalks for example. It is of course possible to advantageously apply this metallization process to only one sidewalk, or to any other area of the shoe for which greater hardness would be desired, such as the areas of competition shoes that can be worn by shocks. with slalom stakes for example.

L'invention a été décrite dans le cas d'une coque de chaussure de ski mais elle pourrait être appliquée à toute coque et chaussure de sport pour planche de glisse, comprenant une surface plastique de liaison destinée à coopérer avec un dispositif de fixation de la planche de glisse. Par exemple, la figure 3 illustre une chaussure 21 de surf des neiges comprenant une zone latérale métallisée 22 pour coopérer avec des mâchoires 24 de dispositifs de fixation 23 dits à « step-in ».The invention has been described in the case of a ski boot shell but it could be applied to any shell and sports shoe for gliding board, comprising a plastic connecting surface intended to cooperate with a fastening device of the ski boot. gliding board. For example, the figure 3 illustrates a snowboard boot 21 comprising a metallized side zone 22 to cooperate with jaws 24 of so-called "step-in" fasteners 23.

Finalement, la solution atteint bien les objets recherchés et présente les avantages suivants :

  • le procédé de fabrication est simple et peu coûteux, s'ajoute à tout autre procédé de fabrication existant pour une chaussure de sport ; le concept de l'invention ne modifie pas la structure de la chaussure, qui présente des parois habituelles, sur lesquelles est ajoutée une couche protectrice superficielle de grande dureté sur certaines zones choisies ;
  • la couche métallique apporte une dureté permettant d'atteindre une résistance de surface efficace aux parties de chaussure particulièrement sollicitées, et limite ainsi grandement leur usure prématurée ;
  • la couche de surface métallique est visible à l'oeil nu et offre une esthétique attrayante.
Finally, the solution achieves the desired objects and has the following advantages:
  • the manufacturing process is simple and inexpensive, in addition to any other existing manufacturing process for a sports shoe; the concept of the invention does not change the structure of the shoe, which has usual walls, on which is added a superficial protective layer of great hardness on selected areas;
  • the metal layer provides a hardness to achieve effective surface resistance to particularly stressed shoe parts, and greatly limits their premature wear;
  • the metal surface layer is visible to the naked eye and offers an attractive aesthetic.
