Description

L'invention se rapporte à une chaussure, notamment de sport, et concerne plus particulièrement une chaussure destinée à la pratique du surf sur neige, ou snowboard. L'invention concerne aussi des chaussures pour la raquette à neige, la planche à roues, la marche, ou autre.The invention relates to a shoe, especially sport, and more particularly relates to a shoe for snowboarding or snowboarding. The invention also relates to shoes for snowshoeing, wheeling, walking, or other.

Une chaussure peut comprendre une tige basse ou une tige haute, et peut être relativement souple ou au contraire plus rigide. La chaussure est dans tous les cas munie d'un semelage externe, lequel est prévu pour relier la tige au sol ou à un engin de sport.A shoe may comprise a low or high upper, and may be relatively flexible or otherwise stiffer. The shoe is in all cases provided with an outer sole, which is intended to connect the rod to the ground or a sports machine.

De manière connue le semelage externe peut être réalisé avec une matière synthétique, telle qu'une matière plastique, moulée ou mise en forme par toute technique. Le semelage externe est donc une pièce qui s'étend en longueur depuis une extrémité arrière jusqu'à une extrémité avant, en largeur entre un côté latéral et un côté médial, et en hauteur entre une face libre, prévue pour contacter le sol ou l'engin de sport, et une face de liaison, prévue pour être solidarisée à la tige.In known manner the outer sole can be made of a synthetic material, such as a plastic material, molded or shaped by any technique. The outer sole is therefore a piece which extends in length from a rear end to a front end, in width between a lateral side and a medial side, and in height between a free face, intended to contact the ground or the ground. sport apparatus, and a connecting face, intended to be secured to the rod.

Il est fréquent que le semelage externe comprenne un corps souple, car cela permet une marche facile et un amortissement des chocs résultant d'impacts ou de la conduite d'un engin.It is common that the outer sole includes a flexible body, as this allows easy walking and damping shocks resulting from impacts or driving a craft.

C'est par exemple le cas en snowboard, où la souplesse du semelage externe remplit les fonctions ci-avant évoquées. On considère qu'un semelage externe souple, ou relativement souple, est adapté à une pratique sportive, comme la conduite d'une planche de snowboard. En effet, l'amortissement des chocs réduit les risques de traumatismes.This is the case, for example, in snowboarding, where the flexibility of the outer soleplate fulfills the functions mentioned above. It is considered that a flexible or relatively flexible outer sole is adapted to a sporting practice, such as driving a snowboard. In fact, shock absorption reduces the risk of trauma.

Cependant, le corollaire est que la conduite est moins précise qu'avec des semelages plus rigides. En effet, ces derniers transmettent mieux les impulsions de conduite. Cependant, ils transmettent aussi les chocs.However, the corollary is that driving is less accurate than with more rigid sowing. Indeed, they transmit better driving impulses. However, they also transmit shocks.

En conséquence, les chaussures connues se classent en deux catégories : celles qui apportent un amortissement satisfaisant avec une précision de conduite modeste, ou celles offrant une précision de conduite élevée avec un amortissement médiocre. En d'autres termes, les chaussures connues ne sont pas adaptées à toutes les situations de conduite. Cela pose problème car la conduite d'une planche n'est pas optimisée dans toutes les phases d'un parcours.As a result, known shoes fall into two categories: those that provide satisfactory damping with modest driving precision, or those offering high driving precision with poor damping. In other words, the known shoes are not suitable for all driving situations. This is a problem because driving a board is not optimized in all phases of a course.

En regard de cette situation, l'invention cherche à optimiser la conduite d'une planche dans toutes ses phases. C'est pourquoi l'invention a notamment pour but d'améliorer un semelage externe, pour obtenir un amortissement satisfaisant ainsi qu'une précision de conduite satisfaisante. En d'autres termes, l'invention veut optimiser le compromis entre amortissement et précision.In view of this situation, the invention seeks to optimize the conduct of a board in all its phases. This is why the purpose of the invention is notably to improve an external sole assembly, to obtain a satisfactory damping as well as a satisfactory driving precision. In other words, the invention wants to optimize the compromise between damping and accuracy.

Dans cette optique, l'invention propose une chaussure comprenant un semelage externe et une tige, le semelage externe comprenant un corps souple qui s'étend en longueur depuis une extrémité arrière jusqu'à une extrémité avant, en largeur entre un côté latéral et un côté médial, et en hauteur entre une face libre et une face de liaison avec la tige.In this regard, the invention provides a shoe comprising an outer sole and a rod, the outer sole comprising a flexible body which extends in length from a rear end to a front end, in width between a lateral side and a medial side, and height between a free face and a connecting face with the rod.

La chaussure selon l'invention est caractérisée par le fait que le semelage externe comprend une monture plate, plus rigide que le corps, et disposée au niveau de la face de liaison, et par le fait qu'au moins une dent s'étend depuis la monture vers la face libre à travers le corps.The shoe according to the invention is characterized in that the outer sole comprises a flat mount, more rigid than the body, and disposed at the connecting face, and in that at least one tooth extends from the mount to the free face through the body.

Par sa souplesse le corps souple permet un amortissement des chocs résultant d'impacts. Les dents portées par la monture, quant à elles, transmettent les impulsions de conduite entre la face de liaison et la face libre. Là où elles se situent, les dents remplissent une fonction de transmission des impulsions. En d'autres termes le semelage externe de la chaussure selon l'invention est à la fois capable d'amortir des chocs et de transmettre des impulsions de conduite, selon la répartition des dents. Il s'ensuit avantageusement que la conduite d'une planche, avec la chaussure selon l'invention, est optimisée dans toutes les phases d'un parcours.By its flexibility the flexible body allows shock absorption impacts resulting from impacts. The teeth carried by the mount, meanwhile, transmit driving pulses between the connecting face and the free face. Where they are located, the teeth fulfill a function of transmission of pulses. In other words the outer sole of the shoe according to the invention is both capable of damping shocks and transmit driving pulses, according to the distribution of teeth. It follows advantageously that the driving of a board, with the shoe according to the invention, is optimized in all phases of a course.

D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, selon des formes de réalisation non limitatives, comment l'invention peut être réalisée, et dans lequel :

  • la figure 1 est une vue en perspective avant d'une chaussure, selon une première forme de réalisation de l'invention,
  • la figure 2 est une vue en perspective avant du semelage externe de la chaussure selon la figure 1,
  • la figure 3 est une vue de dessus, c'est-à-dire de la face de liaison, du semelage externe de la chaussure de la figure 1,
  • la figure 4 est une vue éclatée en perspective avant du semelage externe de la chaussure selon la figure 1,
  • la figure 5 est une vue similaire à la figure 2, selon une deuxième forme de réalisation de l'invention.
Other features and advantages of the invention will be better understood with the aid of the following description, with reference to the appended drawing illustrating, according to non-limiting embodiments, how the invention can be realized, and in which :
  • the figure 1 is a front perspective view of a shoe, according to a first embodiment of the invention,
  • the figure 2 is a perspective view before the outer sole of the shoe according to the figure 1 ,
  • the figure 3 is a top view, that is to say of the connecting face, the outer sole of the shoe of the figure 1 ,
  • the figure 4 is an exploded view in perspective before the outer sole of the shoe according to the figure 1 ,
  • the figure 5 is a view similar to the figure 2 according to a second embodiment of the invention.

Une chaussure 1 visible sur la figure 1 a vocation à accueillir le pied d'un utilisateur.A shoe 1 visible on the figure 1 intended to accommodate the foot of a user.

De manière connue, la chaussure 1 comprend un semelage externe 2 et une tige 3. La chaussure 1 s'étend en longueur depuis une extrémité arrière ou talon 4 jusqu'à une extrémité avant ou pointe 5, et en largeur entre un côté latéral 6 et un côté médial 7. On observe que par corollaire le semelage externe 2 comprend un corps souple 8 qui s'étend en longueur depuis le talon 4 jusqu'à la pointe 5, et en largeur entre le côté latéral 6 et le côté médial 7. La chaussure 1 s'étend en hauteur depuis le semelage 2 jusqu'à une extrémité supérieure 9.In known manner, the shoe 1 comprises an outer sole 2 and a rod 3. The shoe 1 extends in length from a rear end or heel 4 to a front end or tip 5, and in width between a lateral side 6 and a medial side 7. It is observed that by corollary the external soleing 2 comprises a flexible body 8 which extends in length from the heel 4 to the tip 5, and in width between the lateral side 6 and the medial side 7 The shoe 1 extends in height from the soleing 2 to an upper end 9.

Telle que représentée la tige 3 comprend une portion basse 10, prévue pour entourer le pied, ainsi qu'une portion haute 11, prévue pour entourer la cheville. Cependant, il pourrait être envisagé une tige comprenant seulement la portion basse.As shown the rod 3 comprises a lower portion 10, provided to surround the foot, and a high portion 11, provided to surround the ankle. However, it could be considered a rod comprising only the lower portion.

On remarque que la chaussure 1 est munie d'un dispositif de serrage 12, destiné à serrer la tige 3 de manière réversible. Pour ce faire, le dispositif de serrage 12 comprend par exemple des brins de lacet 13, 14 ainsi qu'un mécanisme de serrage réversible. Ces éléments 13, 14, 15 sont bien connus de l'homme du métier, et non détaillés ici.Note that the shoe 1 is provided with a clamping device 12 for clamping the rod 3 in a reversible manner. To do this, the clamping device 12 comprises, for example lace strands 13, 14 and a reversible clamping mechanism. These elements 13, 14, 15 are well known to those skilled in the art, and not detailed here.

La présentation générale de la chaussure étant faite, l'attention va être portée maintenant sur le semelage 2, par exemple en regard de la figure 2.The general presentation of the shoe being made, the attention will now be focused on the sole assembly 2, for example with regard to the figure 2 .

On retrouve donc le corps souple 8 qui, parce qu'il s'étend du talon 4 à la pointe 5 ainsi que du côté latéral 6 au côté médial 7, délimite la périphérie du semelage externe 2. Ce dernier 2 s'étend en hauteur, c'est-à-dire aussi en épaisseur, entre une face libre 21 et une face de liaison 22. Bien entendu, la face libre 21 est destinée à contacter le sol, un dispositif de retenue de la chaussure à un engin de sport, ou encore l'engin lui-même. La face de liaison 22, quant à elle, sert à solidariser le semelage 2 au reste de la chaussure, par exemple par collage.There is thus the flexible body 8 which, because it extends from the heel 4 to the tip 5 and the lateral side 6 to the medial side 7, defines the periphery of the outer sole 2. The latter 2 extends in height , that is to say also in thickness, between a free face 21 and a connecting face 22. Of course, the free face 21 is intended to contact the ground, a device for retaining the shoe to a sports machine , or the craft itself. The connecting face 22, in turn, serves to secure the sole 2 to the rest of the shoe, for example by gluing.

Selon la première forme de réalisation de l'invention, de manière non limitative, le corps souple 8 du semelage externe 2 comprend une couche d'usure 23 ainsi qu'une couche d'amortissement 24.According to the first embodiment of the invention, in a nonlimiting manner, the flexible body 8 of the outer soleplate 2 comprises a wear layer 23 and a damping layer 24.

La couche d'usure 23 s'étend sur toute la surface du semelage 2, c'est-à-dire depuis le talon 4 jusqu'à la pointe 5, ainsi que depuis le côté latéral 6 jusqu'au côté médial 7. En conséquence la couche d'usure 23 délimite la périphérie du semelage 2 évoquée avant, ainsi que la face libre 21. La couche d'usure 23 est par exemple constituée d'éthyle-vinyle-acétate (EVA) mis en forme par injection dans un moule. Cette matière mise en forme selon ce procédé est à la fois résistante à l'usure et légère. La couche d'usure 23 permet aussi un bon amortissement des chocs. On note néanmoins que d'autres matériaux peuvent convenir, comme le caoutchouc qui résiste bien à l'usure, ou autre.The wear layer 23 extends over the entire surface of the sole 2, that is to say from the heel 4 to the tip 5, as well as from the lateral side 6 to the medial side 7. Consequently, the wear layer 23 delimits the periphery of the solenoid 2 mentioned before, as well as the free face 21. The wear layer 23 consists for example of ethyl-vinyl-acetate (EVA) shaped by injection in a mold. This material shaped according to this process is both wear resistant and light. The wear layer 23 also provides good shock absorption. It is noted, however, that other materials may be suitable, such as rubber that is resistant to wear, or other.

La couche d'amortissement supplémentaire 24, quant à elle, s'étend depuis l'extrémité arrière ou talon 4, vers l'avant ou pointe 5, jusqu'au milieu du semelage 2, c'est-à-dire jusqu'à mi-chemin entre le talon 4 et la pointe 5. La couche d'amortissement 24 est interposée entre la couche d'usure 23 et le reste de la chaussure, c'est-à-dire entre la couche d'usure 23 et la tige 3. La couche d'amortissement 24 délimite donc une partie de la face de liaison 22. Cette couche 24 est par exemple constituée d'éthyle-vinyle-acétate (EVA) mis en forme par compression d'une feuille de matière. Cette matière mise en forme selon ce procédé est à la fois apte à amortir les chocs et légère. La solidarisation l'une à l'autre des couches d'usure 23 et d'amortissement 24 se fait par tout moyen tel qu'une application directe de l'une sur l'autre en moule, un collage, ou autre.The additional damping layer 24, in turn, extends from the rear end or heel 4, towards the front or point 5, to the middle of the sole assembly 2, that is to say up to halfway between the heel 4 and the tip 5. The damping layer 24 is interposed between the wear layer 23 and the rest of the shoe, that is to say between the wear layer 23 and the rod 3. The damping layer 24 thus delimits a portion of the connecting face 22. This layer 24 is for example made of ethyl-vinyl-acetate (EVA) shaped by compression of a sheet of material. This material shaped according to this process is both capable of absorbing shocks and light. The interlocking 23 of the wear layers 23 and damping 24 is made by any means such as a direct application of the one on the other mold, gluing, or other.

On observe que, selon la première forme de réalisation de l'invention, le corps souple 8 du semelage externe 2 est constitué exclusivement d'EVA. Ainsi le corps 8 est particulièrement léger.It is observed that, according to the first embodiment of the invention, the flexible body 8 of the outer sole 2 consists exclusively of EVA. Thus the body 8 is particularly light.

Afin de mieux repérer la position des parties constitutives du semelage externe 2, différentes zones de ce dernier sont référencées selon la figure 3. Le semelage 2 présente donc successivement, depuis l'arrière 4 vers l'avant 5, une zone de talon 31, une zone de voute plantaire 32, une zone de métatarse 33, et enfin une zone des orteils ou zone avant 34. On remarque au passage que la couche d'amortissement supplémentaire 24 s'étend depuis le talon 4, dans la zone de talon 31 et dans la zone de voute plantaire 32. Ainsi le semelage externe amortit encore mieux les chocs au niveau du talon du pied de l'utilisateur.In order to better identify the position of the constituent parts of the outer sole assembly 2, different zones of the latter are referenced according to the figure 3 . The sole assembly 2 thus has successively, from the rear 4 forward 5, a heel area 31, a plantar arch area 32, a metatarsal area 33, and finally a toe area or area before 34. Note in passing that the additional damping layer 24 extends from the heel 4, in the heel area 31 and in the plantar arch zone 32. Thus the outer sole cushioning even better impacts at the heel of the foot of the foot. 'user.

Selon l'invention, comme on le comprend notamment à l'aide des figures 4 et 5, le semelage externe 2 comprend une monture plate 41, plus rigide que le corps 8, et disposée au niveau de la face de liaison 22 en étant parallèle à celle-ci, ainsi qu'au moins une dent 42 qui s'étend depuis la monture plate 41 vers la face libre 21 à travers le corps 8.According to the invention, as is understood in particular by means of figures 4 and 5 the outer soleing 2 comprises a flat mount 41, more rigid than the body 8, and disposed at the connecting face 22 being parallel thereto, and at least one tooth 42 which extends from the flat mount 41 to the free face 21 through the body 8.

Bien entendu la couche d'usure 23 s'étend en regard de la monture plate 41 autour de chaque dent. Le semelage 2 amortit les chocs selon toute son étendue, sauf sous la monture. Les dents 42 sont à même de transmettre des impulsions entre la monture 41 et un engin tel qu'une planche de snowboard, laquelle est représentée de manière symbolique et désignée sous la référence B. De par sa localisation, dans le sens de la hauteur de la chaussure, la monture reçoit directement des impulsions du pied de l'utilisateur, lesquelles sont transmises à la planche B par les dents. Cette disposition attribue au semelage 2 des propriétés différentes, d'amortissement ou de transmission, selon la localisation des dents. En d'autres termes le semelage 2 présente l'avantage d'être multifonctionnel.Of course the wear layer 23 extends opposite the flat mount 41 around each tooth. The sole 2 dampens shocks to its full extent, except under the mount. The teeth 42 are able to transmit pulses between the frame 41 and a machine such as a snowboard, which is represented symbolically and designated by the reference B. By its location, in the direction of the height of the shoe, the mount directly receives pulses from the foot of the user, which are transmitted to the board B by the teeth. This provision gives the sole 2 different properties, damping or transmission, depending on the location of the teeth. In other words, the sole assembly 2 has the advantage of being multifunctional.

Comme on le comprend à l'aide de l'ensemble des figures 2 à 5, la monture plate 41 est une plaque, dont l'épaisseur est constante et comprise entre 0,5 et 5mm, sachant que des valeurs de 1 à 2mm ont donné de bons résultats. Chaque dent 42 est une protubérance, par exemple de forme cylindrique, reliée à la plaque ou monture 41.As can be understood by using all of the Figures 2 to 5 , the flat mount 41 is a plate, whose thickness is constant and between 0.5 and 5mm, knowing that values of 1 to 2mm have given good results. Each tooth 42 is a protuberance, for example of cylindrical shape, connected to the plate or frame 41.

Dans le but de faciliter la fabrication de la chaussure 1, il est prévu que la monture 41 et les dents 42 forment une pièce monobloc. Celle-ci est réalisée par exemple avec une matière plastique, telle qu'un polyamide, un polyuréthane, un chlorure de polyvinyle, ou autre. En tout état de cause, la monture 41 et les dents 42 sont faits avec une matière plastique rigide, c'est-à-dire plus rigide que la ou les matières constitutives du corps souple 8.In order to facilitate the manufacture of the shoe 1, it is expected that the frame 41 and the teeth 42 form a single piece. This is carried out for example with a plastic material, such as a polyamide, a polyurethane, a polyvinyl chloride, or other. In any case, the frame 41 and the teeth 42 are made of a rigid plastic material, that is to say more rigid than the constituent material or materials of the flexible body 8.

De manière non limitative, la monture 41 est logée dans une cavité ouverte 43 du corps souple 8, au niveau de la face de liaison 22. La monture 41 prolonge le corps souple 8 au niveau de la face de liaison 22, ce qui rend cette dernière régulière. On peut dire aussi que le dessus de la monture 41 est au même niveau que la face de liaison 22. En conséquence la solidarisation du semelage externe 2 au reste de la tige est plus facile. De plus, la délimitation des zones d'amortissement et de transmission est plus nette, plus précise.Without limitation, the mount 41 is housed in an open cavity 43 of the flexible body 8, at the connecting face 22. The mount 41 extends the flexible body 8 at the connecting face 22, which makes this last regular. It can also be said that the top of the frame 41 is at the same level as the connecting face 22. Consequently, securing the outer sole assembly 2 to the rest of the rod is easier. In addition, the delimitation of the depreciation and transmission zones is clearer and more precise.

Selon la première forme de réalisation de l'invention, la monture 41 et les dents 42 sont localisées dans la zone de métatarse 33 décrite avant. Cela permet notamment de transmettre des impulsions de conduite avec le métatarse du pied. Cette possibilité est utile lors de la conduite d'une planche de snowboard, notamment pour une prise de carre avant.According to the first embodiment of the invention, the frame 41 and the teeth 42 are located in the metatarsal area 33 described before. This allows in particular to transmit driving impulses with the metatarsus of the foot. This possibility is useful when driving a snowboard, especially for a front edge.

On remarque que la monture 41 présente une subdivision latérale 44, située près du côté latéral 6, ainsi qu'une subdivision médiale 45, située près du côté médial 7, la subdivision médiale 45 ayant une surface supérieure à la surface de la subdivision latérale 44. C'est donc la partie du métatarse située du côté du gros orteil qui bénéficie de la plus grande surface d'appui, pour la transmission d'impulsions de conduite.Note that the mount 41 has a lateral subdivision 44, located near the lateral side 6, and a medial subdivision 45, located near the medial side 7, the medial subdivision 45 having a surface greater than the surface of the lateral subdivision 44 This is the part of the metatarsal on the side of the big toe that has the largest support surface, for the transmission of driving impulses.

Il est par exemple prévu que chaque subdivision 44, 45 porte des dents 42. La subdivision latérale 44 en porte un nombre compris entre un et dix, tandis que la subdivision médiale 45 en porte un nombre compris entre un et quinze.It is for example provided that each subdivision 44, 45 carries teeth 42. The lateral subdivision 44 bears a number between one and ten, while the medial subdivision 45 has a number between one and fifteen.

On remarque que l'extrémité 46 d'une dent, ou de plusieurs, s'étend jusqu'au niveau de la face libre 21. Cela signifie que l'extrémité 46 est au niveau de la face libre 21. Cela rend la transmission des impulsions immédiate. Il pourrait alternativement être prévu que l'extrémité 46 soit en retrait par rapport à la face libre 21, pour retarder la transmission d'impulsions. Dans ce cas un léger amortissement peut être préservé au niveau de la monture 41.Note that the end 46 of a tooth, or several, extends to the level of the free face 21. This means that the end 46 is at the free face 21. This makes the transmission of immediate impulses. It could alternatively be provided that the end 46 is set back relative to the free face 21, to delay the transmission of pulses. In this case a slight damping can be preserved at the frame 41.

La deuxième forme de réalisation est présentée brièvement à l'aide de la figure 6. Cette forme utilise les mêmes références que la précédente, car elle en est une simplification.The second embodiment is presented briefly using the figure 6 . This form uses the same references as the previous one, because it is a simplification.

En fait, ici le corps souple 8 du semelage externe 2 comprend uniquement une couche d'usure 23, à l'exclusion de toute couche supplémentaire d'amortissement. Cela simplifie la fabrication de la chaussure 1.In fact, here the flexible body 8 of the outer sole 2 comprises only a wear layer 23, excluding any additional layer of damping. This simplifies the manufacture of the shoe 1.

Bien entendu l'invention n'est pas limitée aux formes de réalisation ci-avant décrites, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the claims that follow.

En particulier, de nombreuses variantes de structures peuvent être prévues pour le corps souple 8, la monture 41, ou les dents 42.In particular, many variants of structures may be provided for the flexible body 8, the frame 41, or the teeth 42.
