Description

L'invention se rapporte à une chaussure destinée à coopérer avec un engin par une action de pédalage, et concerne plus particulièrement des cas où l'engin est un véhicule. Une chaussure selon l'invention peut être utilisée avec un vélo, un triporteur, une voiture à pédales, une machine d'entraînement en salle ou tout autre engin qui nécessite une action de pédalage.The invention relates to a shoe intended to cooperate with a vehicle by a pedaling action, and more particularly relates to cases where the vehicle is a vehicle. A shoe according to the invention can be used with a bicycle, a scooter, a pedal car, an indoor training machine or any other machine that requires a pedaling action.

Dans le domaine du cyclisme, par exemple, la chaussure coopère avec une pédale de l'engin, à savoir ici le vélo, notamment pour le faire avancer. La chaussure est amenée, entre autres fonctions, à transmettre des efforts ou des impulsions de conduite, à transmettre des informations sensorielles, ou à restituer des réactions du sol ou de l'engin lui-même. Afin de remplir ces fonctions, l'art antérieur a proposé des structures pour les chaussures du domaine en cause.In the field of cycling, for example, the shoe cooperates with a pedal of the machine, namely here the bike, especially to advance it. The shoe is brought, among other functions, to transmit forces or driving impulses, to transmit sensory information, or to restore reactions of the ground or the vehicle itself. In order to fulfill these functions, the prior art has proposed structures for the shoes of the field in question.

De manière traditionnelle, une chaussure de cyclisme comprend au moins un semelage et une tige qui définissent un volume de chaussage, et comprend souvent aussi une cale pour la liaison à la pédale. Nous considérons ci-après les deux premiers éléments.In a traditional manner, a cycling shoe comprises at least one sole and a shaft that define a boot volume, and often also includes a shim for the connection to the pedal. We consider below the first two elements.

Tout d'abord le semelage. Celui-ci comprend une subdivision appelée semelage externe. Il s'agit d'une subdivision rigide de la chaussure, dans le sens où elle ne doit pas fléchir longitudinalement, ou seulement très peu. Cela signifie qu'elle ne doit si possible pas se déformer en flexion selon un axe transversal de la chaussure, l'axe étant parallèle au semelage, afin notamment de mieux transmettre à la pédale des impulsions en provenance du bas de jambe d'un utilisateur. Pour ce faire, le semelage externe comprend généralement une ou plusieurs couches de matériaux qui lui confèrent ses propriétés mécaniques, dont la résistance à la flexion.First of all, the sole. This includes a subdivision called outer sole. This is a rigid subdivision of the shoe, in the sense that it should not flex longitudinally, or only very little. This means that, if possible, it should not be deformed in flexion along a transverse axis of the boot, the axis being parallel to the sole, in particular to better transmit to the pedal impulses coming from the lower leg of a user. . To do this, the outer sole generally comprises one or more layers of materials that give it its mechanical properties, including flexural strength.

Maintenant la tige. Il s'agit d'une subdivision de la chaussure destinée à couvrir le pied. La tige comprend généralement de nombreuses pièces, comme un quartier latéral, un quartier médial, une empeigne, une languette, un talon, un contrefort arrière, un embout de protection avant, un dispositif de serrage, une doublure interne, ou autre. La chaussure est obtenue en assemblant et en mettant en trois dimensions des pièces découpées et assemblées à plat, c'est-à-dire en deux dimensions. La tige est associée, de manière connue, à une semelle de montage, pour délimiter un élément chaussant. Selon une première méthode, la tige est collée sur la semelle de montage par une couche de colle. La semelle de montage, appelée aussi première de montage, est relativement rigide, afin de résister au processus de montage. Le collage se fait en tirant la tige pour la plaquer sur la première de montage, sachant qu'une forme est insérée dans la tige. On appelle cela le montage traditionnel sur forme. Cette technique permet d'exercer une pression suffisante pendant le chauffage de la colle, pour obtenir l'élément chaussant. Une deuxième méthode, également connue, consiste à réaliser l'élément chaussant en solidarisant la tige à la première de montage au moyen d'une couture. On appelle cela le montage Strobel. La première de montage est ici une semelle souple, pouvant être cousue, appelée semelle Strobel. Pour chacune des première et deuxième méthodes, la première de montage fait partie du semelage au sens large. En fait ce dernier comprend au moins le semelage externe et la semelle première de montage. Au final, et pour l'essentiel, la chaussure est formée par l'association de l'élément chaussant avec les pièces constitutives du semelage externe. Cela revient à dire que la chaussure comprend un semelage et une tige.Now the stem. This is a subdivision of the shoe intended to cover the foot. The upper generally includes a number of parts, such as a side section, a medial area, a vamp, a tongue, a heel, a rear buttress, a front end cap, a clamping device, an inner liner, or the like. The shoe is obtained by assembling and putting in three dimensions pieces cut and assembled flat, that is to say in two dimensions. The rod is associated, in known manner, with a mounting flange, to delimit a footwear element. According to a first method, the rod is glued to the mounting flange by a layer of glue. The mounting flange, also called the first mounting, is relatively rigid, to resist the mounting process. The gluing is done by pulling the rod to press it on the first of assembly, knowing that a form is inserted in the stem. This is called traditional form fitting. This technique allows to exert sufficient pressure during the heating of the glue, to obtain the footwear element. A second method, also known, is to achieve the footwear element by joining the rod to the first mounting by means of a seam. This is called Strobel editing. The first assembly is here a flexible sole, which can be sewn, called Strobel sole. For each of the first and second methods, the first assembly is part of the assembly in the broad sense. In fact, the latter comprises at least the outer sole and the first mounting sole. In the end, and for the most part, the shoe is formed by the combination of the footwear element with the constituent parts of the outer sole. This is to say that the shoe includes a sole and a rod.

De manière générale, une chaussure selon l'art antérieur donne satisfaction, dans le sens où elle permet à chaque utilisateur de conduire correctement son engin. En effet, l'utilisateur est à même de transmettre des efforts ou des impulsions de conduite, ou de percevoir des informations sensorielles, ainsi que des réactions du sol ou de l'engin lui-même. Cependant, il est malgré tout apparu qu'une chaussure selon l'art antérieur présente quelques inconvénients.In general, a shoe according to the prior art is satisfactory, in the sense that it allows each user to properly drive his machine. Indeed, the user is able to transmit efforts or driving impulses, or to perceive sensory information, as well as reactions of the ground or the vehicle itself. However, it has nevertheless appeared that a shoe according to the prior art has some disadvantages.

Tout d'abord, elle est source de fatigues, notamment lors d'utilisations intenses, par exemple pendant des épreuves sportives. On peut dire en d'autres termes que le rendement d'une chaussure selon l'art antérieur est insuffisant. Cela signifie que l'utilisateur doit fournir plus d'énergie que celle théoriquement nécessaire pour l'utilisation de l'engin. Une raison à cela est l'écart trop important entre le pied et l'axe de rotation de la pédale. En effet, il est connu que plus la plante du pied est proche de l'axe de la pédale, meilleur est le rendement de pédalage. Une autre raison est le poids relativement élevé de la chaussure, ce qui a pour conséquence par exemple d'augmenter son inertie mécanique.First, it is a source of fatigue, especially during intense use, for example during sports events. In other words, it can be said that the performance of a shoe according to the prior art is insufficient. This means that the user must provide more energy than that theoretically necessary for the use of the machine. One reason for this is the excessive gap between the foot and the axis of rotation of the pedal. Indeed, it is known that the more the sole of the foot is close to the axis of the pedal, the better the pedaling efficiency. Another reason is the relatively high weight of the shoe, which for example has the effect of increasing its mechanical inertia.

Ensuite, une chaussure selon l'art antérieur présente une structure compliquée, ce qui rend sa fabrication longue et coûteuse.Then, a shoe according to the prior art has a complicated structure, which makes its manufacture long and expensive.

EP 0 749 704 divulgue une sandale comprenant une semelle, une bride raccordée à la semelle et une bande de raccordement raccordée à la bride. EP 0 749 704 discloses a sandal comprising a sole, a flange connected to the sole and a connecting strip connected to the flange.

Par rapport à cela, l'invention cherche globalement à améliorer une chaussure destinée à coopérer avec un engin par une action de pédalage. Il s'agit notamment d'augmenter le rendement de pédalage et/ou de réduire la fatigue d'un utilisateur. Cela revient à dire que l'invention veut améliorer les performances liées à l'utilisation, par exemple lors d'épreuves sportives. L'invention cherche aussi à réduire le coût et la durée de fabrication d'une chaussure, l'idée sous-jacente étant d'en simplifier la structure.In relation to this, the invention generally seeks to improve a shoe intended to cooperate with a machine by a pedaling action. These include increasing the pedaling efficiency and / or reducing the fatigue of a user. This amounts to saying that the invention wants to improve the performance related to the use, for example during sports events. The invention also seeks to reduce the cost and duration of manufacture of a shoe, the underlying idea being to simplify the structure.

Pour ce faire, l'invention selon la revendication 1 propose une chaussure destinée à coopérer avec un engin par une action de pédalage, la chaussure comprenant une base qui s'étend en longueur depuis une extrémité arrière jusqu'à une extrémité avant, en largeur entre un bord latéral et un bord médial et en épaisseur entre une face de coopération avec l'engin et une face interne , la base présentant, depuis l'extrémité arrière jusqu'à l'extrémité avant, une zone arrière, une zone centrale, une zone de métatarse et une zone avant, la chaussure comprenant une paroi latérale et une paroi médiale.To do this, the invention according to claim 1 proposes a shoe intended to cooperate with a machine by a pedaling action, the shoe comprising a base which extends in length from a rear end to a front end, in width between a lateral edge and a medial edge and in thickness between a face of cooperation with the machine and an inner face, the base having, from the rear end to the front end, a rear zone, a central zone, a metatarsal area and a front area, the shoe comprising a side wall and a medial wall.

La chaussure selon l'invention est caractérisée par le fait que la paroi latérale et la paroi médiale sont directement solidarisées à la base, et par le fait que la base, la paroi latérale et la paroi médiale sont des subdivisions rigides de la chaussure.The shoe according to the invention is characterized in that the side wall and the medial wall are directly secured to the base, and in that the base, the side wall and the medial wall are rigid subdivisions of the shoe.

Par cet agencement, les parois latérale et médiale participent à la résistance en flexion longitudinale de la chaussure. En d'autres termes, les parois en cause s'opposent à une flexion de la chaussure selon un axe transversal de celle-ci, l'axe étant parallèle à la base. Il s'agit d'une différence fonctionnelle par rapport à une chaussure selon l'art antérieur, pour laquelle la résistance en flexion est obtenue au moins en très grande partie, sinon totalement, par le semelage externe. On peut dire que l'invention modifie la répartition des efforts induits par les sollicitations en flexion longitudinale, ces efforts se localisant avec l'invention de manière significative au niveau de la paroi latérale et au niveau de la paroi médiale. Par corollaire, avec l'invention, il est possible de réaliser une chaussure dont la base présente une épaisseur réduite par rapport à celle d'un semelage d'une chaussure selon l'art antérieur, pour obtenir une chaussure dont la résistance en flexion est satisfaisante, puisque les parois latérale et médiale participent à cette résistance en flexion.By this arrangement, the lateral and medial walls participate in the longitudinal flexural resistance of the shoe. In other words, the walls in question oppose bending of the boot along a transverse axis thereof, the axis being parallel to the base. This is a functional difference with respect to a shoe according to the prior art, for which the flexural strength is obtained at least in very large part, if not totally, by the outer sole. It can be said that the invention modifies the distribution of the forces induced by the longitudinal bending stresses, these efforts being localized with the invention significantly at the level of the lateral wall and at the level of the medial wall. By corollary, with the invention, it is possible to make a shoe whose base has a reduced thickness compared to that of a sole of a shoe according to the prior art, to obtain a shoe whose flexural strength is satisfactory, since the lateral and medial walls participate in this flexural strength.

Parmi les effets techniques qui en découlent, on peut citer le rapprochement du pied de la face de coopération de la base. Etant donné que celle-ci prend appui sur la pédale, comme on le verra mieux dans la suite de la description, la plante du pied se retrouve plus près de l'axe de rotation de la pédale. En conséquence, de manière avantageuse, le rendement de pédalage augmente et la fatigue de l'utilisateur se réduit.Among the technical effects that result, we can mention the approximation of the foot of the cooperation face of the base. Given that it is supported on the pedal, as will be seen better in the following description, the sole of the foot is closer to the axis of rotation of the pedal. As a result, advantageously, the pedaling efficiency increases and user fatigue is reduced.

Un autre effet technique qui résulte de la réduction de l'épaisseur de la base est la réduction du poids de la région inférieure de la chaussure. Cette région est plus légère que la même région d'une chaussure selon l'art antérieur et au final, avec l'invention, c'est toute la chaussure qui est plus légère. On peut dire que l'invention réduit l'inertie mécanique de la chaussure. Un avantage qui en découle est, là aussi, une réduction de la fatigue de l'utilisateur.Another technical effect that results from the reduction of the thickness of the base is the reduction of the weight of the lower region of the shoe. This region is lighter than the same region of a shoe according to the prior art and in the end, with the invention, the whole shoe is lighter. It can be said that the invention reduces the mechanical inertia of the shoe. A resulting benefit is, again, a reduction of user fatigue.

On remarque que deux effets techniques, à savoir la réduction de la distance entre le pied et l'axe de la pédale d'une part, ainsi que la réduction de la masse de la chaussure d'autre part, se conjuguent pour réduire la fatigue de l'utilisateur, ou pour améliorer ses performances.We note that two technical effects, namely the reduction of the distance between the foot and the axis of the pedal on the one hand, and the reduction of the mass of the shoe on the other hand, combine to reduce fatigue of the user, or to improve his performance.

D'autres avantages sont obtenus grâce au fait que la chaussure selon l'invention présente une structure simplifiée, par rapport à une chaussure selon l'art antérieur, dans le sens où elle est fabriquée avec un nombre réduit de pièces. Il s'agit notamment d'une réduction des coûts de fabrication et d'une réduction de la durée de fabrication.Other advantages are obtained thanks to the fact that the shoe according to the invention has a simplified structure, compared to a shoe according to the prior art, in the sense that it is manufactured with a small number of parts. These include a reduction in manufacturing costs and a reduction in manufacturing time.

De manière générale, on peut dire que l'invention améliore une chaussure destinée à coopérer avec un engin par une action de pédalage.In general, it can be said that the invention improves a shoe intended to cooperate with a machine by a pedaling action.

Les formes de réalisation de l'invention qui vont être décrites après concernent plus spécialement une chaussure pour la pratique du cyclisme. Cependant, l'invention s'applique à d'autres domaines tels que ceux évoqués avant.The embodiments of the invention which will be described below relate more particularly to a shoe for the practice of cycling. However, the invention applies to other fields such as those mentioned before.

C'est à l'aide des figures 1 à 7 qu'est présentée la première forme. Tout d'abord, sur la figure 1, on peut voir une chaussure 1 prévue pour accueillir le pied de l'utilisateur, ainsi qu'une pédale 2 destinée à coopérer avec la chaussure. On précise que la pédale ne sera pas décrite en détail ici, car familière à l'homme du métier.It is with the help of Figures 1 to 7 that is presented the first form. First, on the figure 1 , one can see a shoe 1 provided to accommodate the foot of the user, and a pedal 2 for cooperating with the shoe. It is specified that the pedal will not be described in detail here, since familiar to the skilled person.

De manière connue, comme on peut le voir sur les figures 1 à 4, la chaussure 1 comprend une base 3 qui s'étend en longueur, selon une direction longitudinale L, depuis une extrémité arrière 4 jusqu'à une extrémité avant 5, en largeur, selon une direction transversale W, entre un bord latéral 6 et un bord médial 7, et en épaisseur entre une face de coopération 8 avec l'engin et une face interne 9. On verra par la suite que la face de coopération 8 peut entrer en contact avec la pédale 2 de manière directe ou de manière indirecte. On verra aussi que la face interne 9, quant à elle, peut entrer en contact avec le pied de l'utilisateur directement ou indirectement.In a known manner, as can be seen in the Figures 1 to 4 , the boot 1 comprises a base 3 which extends in length, in a longitudinal direction L, from a rear end 4 to a front end 5, in width, in a transverse direction W, between a lateral edge 6 and a medial edge 7, and in thickness between a cooperation face 8 with the machine and an inner face 9. It will be seen later that the cooperation face 8 can come into contact with the pedal 2 directly or indirectly. We will also see that the inner face 9, for its part, can come into contact with the foot of the user directly or indirectly.

Pour faciliter la description de la chaussure, on précise que la base 3 présente, depuis l'extrémité arrière 4 jusqu'à l'extrémité avant 5, une zone arrière 11, prévue pour venir en regard du talon du pied, une zone centrale 12, prévue pour venir en regard de la voûte plantaire, une zone de métatarse 13, prévue pour venir en regard du métatarse, et une zone avant 14, prévue pour venir en regard des orteils.To facilitate the description of the shoe, it is specified that the base 3 has, from the rear end 4 to the front end 5, a rear zone 11, provided to come opposite the heel of the foot, a central zone 12 , planned to come next to the arch, a metatarsal area 13, intended to come opposite the metatarsal, and a front zone 14, provided to come next to the toes.

La chaussure comprend également une paroi latérale 15 et une paroi médiale 16, lesquelles seront décrites plus en détail après.The shoe also includes a side wall 15 and a medial wall 16, which will be described in more detail later.

Selon l'invention, la paroi latérale 15 et la paroi médiale 16 sont directement solidarisées à la base 3 et, respectivement, la base 3, la paroi latérale 15 et la paroi médiale 16 sont des subdivisions rigides de la chaussure. On précise au passage qu'une subdivision est une partie de la chaussure. Cela signifie que, même si elles peuvent être flexibles, les subdivisions ne peuvent pas s'allonger ou se raccourcir dans des conditions habituelles d'utilisation. On peut dire d'une autre façon que ces parties ne possèdent pas de propriété de déformation élastique qui leur permettrait de s'allonger ou de se raccourcir, et ainsi elles ne peuvent ni former des plis ni se froisser. En conséquence la base 3, la paroi latérale 15 et la paroi médiale 16 délimitent un logement rigide pour l'accueil du pied. Par cet agencement, les parois latérale 15 et médiale 16 participent à la résistance en flexion longitudinale de la chaussure, au moins au niveau de la jonction avec la base. En d'autres termes, les parois en cause s'opposent à une flexion de la chaussure selon un axe transversal de celle-ci, l'axe étant parallèle à la base. Il s'agit d'une différence fonctionnelle par rapport à une chaussure selon l'art antérieur, pour laquelle la résistance en flexion est obtenue au moins en très grande partie, sinon totalement, par le semelage externe. On peut dire que l'invention modifie la répartition des efforts induits par les sollicitations en flexion longitudinale, ces efforts se localisant avec l'invention de manière significative au niveau de la paroi latérale et au niveau de la paroi médiale. On observe que la paroi latérale 15 est continue selon toute la longueur de la base 3, dans le sens où elle longe la zone arrière 11, la zone centrale 12, la zone de métatarse 13 et la zone avant 14. De la même façon la paroi médiale 16 est continue selon toute la longueur de la base 3, dans le sens où elle longe la zone arrière 11, la zone centrale 12, la zone de métatarse 13 et la zone avant 14. Par corollaire, avec l'invention, la base présente ici une épaisseur réduite par rapport à celle d'un semelage d'une chaussure selon l'art antérieur, pour obtenir une chaussure dont la résistance en flexion est satisfaisante.According to the invention, the side wall 15 and the medial wall 16 are directly secured to the base 3 and, respectively, the base 3, the side wall 15 and the medial wall 16 are rigid subdivisions of the shoe. It is specified in passing that a subdivision is a part of the shoe. This means that even if they can be flexible, the subdivisions can not be lengthened or shortened under usual conditions of use. It may be said in another way that these parts do not possess an elastic deformation property which would allow them to lengthen or shorten, and thus they can not form folds or wrinkle. Consequently, the base 3, the lateral wall 15 and the medial wall 16 delimit a rigid housing for receiving the foot. By this arrangement, the lateral and medial walls 16 participate in the longitudinal flexural resistance of the boot, at least at the junction with the base. In other words, the walls in question oppose bending of the boot along a transverse axis thereof, the axis being parallel to the base. This is a functional difference with respect to a shoe according to the prior art, for which the flexural strength is obtained at least in very large part, if not totally, by the outer sole. It can be said that the invention modifies the distribution of the forces induced by the longitudinal bending stresses, these efforts being localized with the invention significantly at the level of the lateral wall and at the level of the medial wall. We observe that the side wall 15 is continuous along the entire length of the base 3, in the sense that it runs along the rear zone 11, the central zone 12, the metatarsal zone 13 and the front zone 14. In the same way the medial wall 16 is continuous along the entire length of the base 3, in the sense that it runs along the rear zone 11, the central zone 12, the metatarsal zone 13 and the front zone 14. By corollary, with the invention, the base present here a reduced thickness compared to that of a sole of a shoe according to the prior art, to obtain a shoe whose flexural strength is satisfactory.

Selon la première forme de réalisation, la chaussure 1 comprend une paroi arrière 17 directement solidarisée à la base 3 et une paroi avant 18 directement solidarisée à la base 3, les parois arrière 17 et avant 18 étant des subdivisions rigides de la chaussure, les paroi arrière 17, latérale 15, avant 18 et médiale 16 formant une ceinture périphérique. Cela signifie que les parois arrière 17, latérale 15, avant 18 et médiale 16 se prolongent les unes les autres autour de la base 3. On précise que la paroi arrière 17 et la paroi avant 18 ne possèdent pas elles non plus de propriété de déformation élastique qui leur permettrait de s'allonger ou de se raccourcir, et qu'ainsi elles ne peuvent ni former des plis ni se froisser. En conséquence, au final, ce sont la base 3, la paroi arrière 17, la paroi latérale 15, la paroi avant 18 et la paroi médiale 16 qui délimitent le logement rigide pour l'accueil du pied. Par cet agencement, l'ensemble constitué par la base 3 et les parois 15, 16, 17, 18 délimite un volume de chaussage rigide en flexion longitudinale, et rigide aussi en torsion. Cela augmente l'aptitude de la chaussure à transmettre des impulsions de conduite, des informations sensorielles, des réactions du sol ou de l'engin, ou autre.According to the first embodiment, the boot 1 comprises a rear wall 17 directly secured to the base 3 and a front wall 18 directly secured to the base 3, the rear walls 17 and before 18 being rigid subdivisions of the boot, the walls rear 17, lateral 15, before 18 and medial 16 forming a peripheral belt. This means that the rear walls 17, lateral 15, before 18 and medial 16 extend one another around the base 3. It is specified that the rear wall 17 and the front wall 18 do not have any deformation property either. elastic that would allow them to lie down or shorten, and so they can not form folds or wrinkles. Consequently, in the end, it is the base 3, the rear wall 17, the side wall 15, the front wall 18 and the medial wall 16 which delimit the rigid housing for receiving the foot. By this arrangement, the assembly constituted by the base 3 and the walls 15, 16, 17, 18 delimits a rigid boot section in longitudinal flexion, and rigid also in torsion. This increases the ability of the shoe to transmit driving impulses, sensory information, ground or gear reactions, or the like.

De manière non limitative, la base 3 et chacune des parois 15, 16, 17, 18 constituent une pièce en forme de berceau dont la structure est continue. Cela signifie par exemple que chacune des parois 15, 16, 17, 18 est un prolongement de la base dans un sens d'éloignement de la face interne 9. Il s'agit là de la structure la plus simple, laquelle présente l'avantage de la facilité de fabrication, et d'un plus faible coût de production du fait de la conformation en une seule partie. Rien n'empêche cependant, alternativement, de prévoir des cas pour lesquels l'une au moins des parois, voire toutes, sont rapportées et rendues solidaires de la base, par tout moyen tel qu'un collage ou tout équivalent.Without limitation, the base 3 and each of the walls 15, 16, 17, 18 constitute a cradle-shaped piece whose structure is continuous. This means for example that each of the walls 15, 16, 17, 18 is an extension of the base in a direction away from the inner face 9. This is the simplest structure, which has the advantage ease of manufacture, and a lower production cost due to the conformation in one part. Nothing, however, prevents, alternatively, to provide cases for which at least one or all walls are reported and made integral with the base, by any means such as a collage or any equivalent.

La paroi arrière 17 est strictement convexe à l'extérieur de la chaussure et, par voie de conséquence, strictement concave à l'intérieur de la chaussure, c'est-à-dire en regard du volume chaussant. En conséquence la paroi arrière présente un arrondi qui, à l'extérieur, facilite le déroulement du pied lors de la marche et qui, à l'intérieur, enveloppe et maintient le talon du pied, à la manière d'un bol.The rear wall 17 is strictly convex to the outside of the boot and, consequently, strictly concave inside the boot, that is to say facing the footwear volume. As a result, the rear wall has a rounded surface which, on the outside, facilitates the unwinding of the foot when walking and which, inside, wraps and maintains the heel of the foot, in the manner of a bowl.

La paroi avant 18, quant à elle, est aussi strictement convexe à l'extérieur de la chaussure et, par voie de conséquence, strictement concave à l'intérieur de la chaussure, en regard du volume chaussant. Il s'ensuit que la paroi avant présente un arrondi qui, à l'extérieur de la chaussure, facilite le déroulement du pied lors de la marche et qui, à l'intérieur de la chaussure, enveloppe les orteils.The front wall 18, meanwhile, is also strictly convex to the outside of the shoe and, consequently, strictly concave inside the shoe, opposite the footwear volume. It follows that the front wall has a rounded portion which, on the outside of the shoe, facilitates the unwinding of the foot when walking and which, inside the shoe, wraps the toes.

On peut observer que l'une des parois 15, 16, 17, 18 au moins présente des orifices 21. Ceux-ci sont tous désignés par la même référence pour des raisons de commodité. De manière non limitative, la paroi latérale 15 présente plusieurs orifices, et la paroi médiale 16 présente plusieurs orifices. Certains de ceux-ci s'étendent aussi au niveau de la paroi arrière 17. Il peut éventuellement être prévu d'en ménager au niveau de la paroi avant 18. Dans tous les cas les orifices allègent la chaussure, et permettent aussi une aération du volume chaussant. Cet agencement contribue, d'une part, à l'amélioration des performances parce que la matière enlevée réduit l'inertie mécanique et, d'autre part, à l'amélioration du confort par évacuation d'une partie de l'humidité et/ou de la chaleur générée par le pied. Cet agencement permet encore une certaine flexibilité transversale pour s'adapter au contour du pied lors du serrage des parois latérale et médiale, comme on va le voir plus loin.It can be seen that at least one of the walls 15, 16, 17, 18 has openings 21. These are all designated by the same reference for the sake of convenience. Without limitation, the side wall 15 has several orifices, and the medial wall 16 has several orifices. Some of these also extend at the level of the rear wall 17. It may optionally be provided to provide at the front wall 18. In all cases the orifices lighten the boot, and also allow aeration of the footwear volume. This arrangement contributes, on the one hand, to the improvement of the performances because the removed material reduces the mechanical inertia and, on the other hand, to the improvement of the comfort by evacuation of a part of the moisture and / or heat generated by the foot. This arrangement still allows a certain transverse flexibility to adapt to the contour of the foot during the clamping of the lateral and medial walls, as will be seen below.

Toujours en rapport avec les dispositions des parois, on précise que la chaussure 1 présente une ouverture supérieure 22 qui s'étend en regard de la zone arrière 11, en regard de la zone centrale 12 et en partie au moins en regard de la zone de métatarse 13. Il s'agit là de permettre le passage du pied pour chausser ou déchausser. En complément, la chaussure comprend un dispositif de serrage 23 des parois latérale 15 et médiale 16. Par son action, le dispositif de serrage 23 permet le maintien du pied dans le volume chaussant pendant l'utilisation de la chaussure. En effet, la paroi latérale 15 présente une extrémité libre 25 et la paroi médiale 16 présente une extrémité libre 26, extrémités qui sont sollicitées l'une vers l'autre par le dispositif de serrage 23 lorsque l'utilisateur actionne ce dernier. Cela est possible parce que, même si le matériau qui les constitue est rigide, les parois latérale 15 et médiale 16 sont déformables en flexion transversale au niveau de leurs extrémités libres respectives, selon la direction W. Par contre les parois ne se déforment pas en flexion transversale au niveau de la base 3, parce qu'elles sont solidarisées à cette dernière. Seules les extrémités libres 25, 26 des parois peuvent fléchir comme seule l'extrémité d'un plongeoir peut fléchir, si l'on veut présenter le phénomène par comparaison. On prévoit d'ailleurs des cas pour lesquels l'épaisseur de la paroi latérale et/ou l'épaisseur de la paroi médiale se réduit depuis la base 3 vers l'extrémité libre 25, 26.Still in relation to the provisions of the walls, it is specified that the boot 1 has an upper opening 22 which extends opposite the rear zone 11, opposite the central zone 12 and partly at least opposite the metatarsal 13. This is to allow the passage of the foot to shoe or barefoot. In addition, the shoe comprises a clamping device 23 of the lateral and medial walls 16. By its action, the clamping device 23 allows the foot to be held in the footwear during use of the boot. Indeed, the side wall 15 has a free end 25 and the medial wall 16 has a free end 26, ends which are urged towards one another by the clamping device 23 when the user actuates the latter. This is possible because, even if the material constituting them is rigid, the lateral and medial walls 16 are deformable in transverse flexion at their respective free ends, along the direction W. On the other hand, the walls do not deform into transverse flexion at the base 3, because they are secured to the latter. Only the free ends 25, 26 of the walls can bend as only the end of a diving board can bend, if we want to present the phenomenon by comparison. In addition, cases are provided for which the thickness of the side wall and / or the thickness of the medial wall is reduced from the base 3 towards the free end 25, 26.

A titre d'exemple non limitatif, sans forcément rentrer dans les détails, on précise que le dispositif de serrage 23 comprend des passants latéraux 27, des passants médiaux 28, un lien 29 qui chemine par les passants et, éventuellement, un mécanisme de blocage du lien, le mécanisme n'étant pas représenté ici. Il doit être compris qu'un passant est un agencement prévu pour guider le lien, comme par exemple un trou dans l'esprit d'un oeillet, un crochet, une chape portant une poulie, ou tout élément équivalent. Le lien, quant à lui, peut être un tronçon de corde, de câble, ou autre.By way of non-limiting example, without necessarily going into the details, it is specified that the clamping device 23 comprises lateral loops 27, medial loops 28, a link 29 which travels through the loops and, optionally, a locking mechanism link, the mechanism is not represented here. It should be understood that a passerby is an arrangement intended to guide the link, such as a hole in the mind of an eyelet, a hook, a clevis carrying a pulley, or any equivalent element. The link, meanwhile, can be a stretch of rope, cable, or other.

Toujours en ce qui concerne la première forme de réalisation de l'invention, et ce de manière non limitative, la base 3 et les parois 15, 16, 17, 18 sont constituées ici de fibres et/ou de portions de fibres solidarisées entre elles par une matrice de matière synthétique. Cette association de matériaux offre de multiples possibilités pour l'élaboration du logement rigide qui accueille le pied. Par exemple, pour l'essentiel, les fibres et/ou les portions de fibres sont en carbone. Ce matériau rend la base et les parois, c'est-à-dire en fait le logement pour le pied, à la fois rigide et léger. En conséquence la chaussure convient bien à une utilisation sportive et intense. On précise que la matrice de matière synthétique, c'est-à-dire le matériau qui sert de liant aux fibres, est par exemple une résine thermodurcissable, une matière thermoformable telle qu'un polyuréthane ou autre, ou tout matériau équivalent. En ce qui concerne les fibres, en alternative au carbone il est possible d'utiliser le verre, qui est économique, l'aramide, pour ses propriétés mécaniques qui représentent dans certains cas une alternative intéressante par rapport aux propriétés du carbone, ou autre.Still with regard to the first embodiment of the invention, and in a nonlimiting manner, the base 3 and the walls 15, 16, 17, 18 are constituted here of fibers and / or portions of fibers joined together. by a matrix of synthetic material. This combination of materials offers multiple possibilities for the development of the rigid housing that welcomes the foot. For example, for the most part, the fibers and / or fiber portions are carbon. This material makes the base and the walls, that is to say, the housing for the foot, both rigid and lightweight. As a result the shoe is well suited for sporty and intense use. It is specified that the matrix of synthetic material, that is to say the material which serves as a fiber binder, is for example a thermosetting resin, a thermoformable material such as a polyurethane or the like, or any equivalent material. Regarding the fibers, as an alternative to carbon it is possible to use the glass, which is economical, the aramid, for its mechanical properties which represent in some cases an interesting alternative to the properties of carbon, or other.

En ce qui concerne les dimensions, toujours dans le cas d'emploi de fibres, les épaisseurs de la base 3 et des parois 15, 16, 17, 18 sont comprises entre 0,3 et 2 mm, sachant que des valeurs comprises entre 0,5 et 1 mm ont donné de bons résultats. La pièce constituée par la base et les parois est donc fine, particulièrement au niveau de la base, par comparaison avec le semelage externe d'une chaussure selon l'art antérieur. C'est pourquoi la chaussure selon l'invention permet au pied de se situer plus près de l'axe de rotation de la pédale, ce qui a notamment pour conséquence une amélioration du rendement de pédalage. Parmi les avantages qui en découlent, on peut citer une fatigue réduite pour un effort donné, ou une amélioration des performances lors d'épreuves sportives intenses.Regarding the dimensions, always in the case of use of fibers, the thicknesses of the base 3 and the walls 15, 16, 17, 18 are between 0.3 and 2 mm, knowing that values between 0 5 and 1 mm gave good results. The piece constituted by the base and the walls is therefore thin, particularly at the level of the base, compared with the outer sole of a shoe according to the prior art. This is why the shoe according to the invention allows the foot to be closer to the axis of rotation of the pedal, which in particular results in an improvement in pedaling efficiency. Among the benefits that result are reduced fatigue for a given effort, or improved performance during intense sporting events.

De manière non limitative, encore dans le cas d'emploi de fibres, l'épaisseur de chaque paroi 15, 16, 17, 18 est comprise entre 50 et 150 % de l'épaisseur de la base 3. Cela homogénéise la structure de la pièce formée par la base et les parois. Un avantage qui en découle est une fabrication simple et facile. En effet, il suffit d'appliquer une ou plusieurs couches de fibres de façon régulière sur une forme, c'est-à-dire un élément dont la géométrie est similaire à celle d'un pied, puis de rendre la matrice rigide, pour obtenir la pièce.Without limitation, still in the case of use of fibers, the thickness of each wall 15, 16, 17, 18 is between 50 and 150% of the thickness of the base 3. This homogenizes the structure of the piece formed by the base and the walls. An advantage that arises is a simple and easy manufacturing. Indeed, it suffices to apply one or more layers of fibers in a regular manner on a shape, that is to say an element whose geometry is similar to that of a foot, then to make the matrix rigid, for get the piece.

De manière alternative, mais toujours dans l'esprit de la première forme de réalisation de l'invention, la base 3 et les parois 15, 16, 17, 18 sont constituées d'une matière plastique. Dans le cas où la base et les parois forment une pièce dont la structure est continue, la matière plastique peut être mise en oeuvre par toute technique connue telle que le moulage par injection, l'impression en trois dimensions par une imprimante spécialisée, la découpe d'un bloc de matière par exemple au moyen d'un machine à commande numérique à cinq axes, ou par toute autre technique appropriée. L'injection de matière présente l'avantage d'une rapidité de fabrication. L'impression en trois dimensions présente l'avantage de la facilité d'évolution, dans le sens où une simple modification de programmation permet de faire évoluer les caractéristiques techniques de la chaussure. Par exemple, il peut être très simple de modifier l'épaisseur de la base ou d'une paroi. Dans tous les cas, la pièce obtenue est simple par rapport à ce que propose l'art antérieur du fait de sa structure monobloc.Alternatively, but still in the spirit of the first embodiment of the invention, the base 3 and the walls 15, 16, 17, 18 are made of a plastics material. In the case where the base and the walls form a part whose structure is continuous, the plastic material can be implemented by any known technique such as injection molding, three-dimensional printing by a specialized printer, cutting a block of material for example by means of a five-axis numerical control machine, or by any other suitable technique. The injection of material has the advantage of rapid manufacturing. Three-dimensional printing has the advantage of ease of evolution, in the sense that a simple modification of programming makes it possible to change the technical characteristics of the shoe. For example, it can be very simple to change the thickness of the base or wall. In all cases, the piece obtained is simple compared to what the prior art proposes because of its monobloc structure.

En ce qui concerne les dimensions, pour l'invention et toujours dans le cas d'utilisation de matière plastique, l'épaisseur de la base 3 est comprise entre 1 et 6 mm, et l'épaisseur de chaque paroi 15, 16, 17, 18 est comprise entre 1 et 3 mm. Dans certains cas, on l'a déjà dit, l'épaisseur des parois se réduit vers les extrémités libres. Les valeurs indiquées sont usuelles dans le domaine de l'injection des matières plastiques. Elles peuvent aussi facilement être obtenues en mettant en oeuvre les autres techniques évoquées ci-avant.Regarding the dimensions, for the invention and always in the case of use of plastic material, the thickness of the base 3 is between 1 and 6 mm, and the thickness of each wall 15, 16, 17 , 18 is between 1 and 3 mm. In some cases, it has already been said, the thickness of the walls is reduced to the free ends. The values indicated are usual in the field of injection molding of plastics. They can also easily be obtained by implementing the other techniques mentioned above.

On a vu que la première forme de réalisation de l'invention est tournée vers une chaussure de cyclisme. C'est pourquoi, comme on peut particulièrement l'observer sur la figure 4, de manière non obligatoire la chaussure 1 comprend une cale 31 disposée dans la zone de métatarse 13, la cale étant prévue pour coopérer avec une pédale 2 de l'engin. Parce qu'elle est bien connue de l'homme du métier, la cale n'est pas décrite en détail ici. On précise néanmoins que, par exemple, la cale 31 comprend plusieurs éléments, comme une plaque interne 32, des éléments d'accrochage externes 33, 34, et des vis 35 pour solidariser la plaque interne aux éléments d'accrochage en traversant la base 3. La cale 31 garantit un maintien précis de la chaussure 1 par rapport à la pédale 2. En conséquence le rendement de conduite est plus constant. Selon la première forme de réalisation, la cale 31 comprend au moins une vis 35 dont la tête 36 est située du côté de la face interne 9 de la base 3. En fait, pour chaque vis la tête 36 est située du côté de la face interne 9, par exemple en prenant place dans l'épaisseur de la plaque interne 32. Cela réduit l'encombrement de la cale 31 à l'intérieur du volume chaussant, et de ce fait le pied peut rester au plus près de la pédale pendant la conduite de l'engin. On a déjà vu que cette proximité va dans le sens d'un meilleur rendement de pédalage.We have seen that the first embodiment of the invention is turned towards a cycling shoe. This is why, as we can particularly observe on the figure 4 , non-mandatory shoe 1 comprises a shim 31 disposed in the metatarsal area 13, the wedge being provided to cooperate with a pedal 2 of the machine. Because she is well known to the man of profession, the hold is not described in detail here. However, it is specified that, for example, the shim 31 comprises several elements, such as an inner plate 32, external fastening elements 33, 34, and screws 35 for securing the inner plate to the fastening elements through the base 3 The wedge 31 guarantees a precise support of the boot 1 with respect to the pedal 2. As a result, the driving efficiency is more constant. According to the first embodiment, the spacer 31 comprises at least one screw 35 whose head 36 is located on the side of the inner face 9 of the base 3. In fact, for each screw the head 36 is located on the side of the face internal 9, for example taking place in the thickness of the inner plate 32. This reduces the size of the wedge 31 within the footwear volume, and thus the foot can stay as close to the pedal during driving the craft. We have already seen that this proximity is in the direction of a better pedaling performance.

A l'aide des figures 5 et 6 on peut voir que, dans la zone de métatarse 13, la base 3 présente une cavité 37 ouverte du côté de la face interne 9. Cette cavité accueille la plaque 32 de la cale 31, ainsi que les têtes 36 des vis 35. De ce fait la plaque et les têtes des vis affleurent le reste de la face interne 9 de la base 3. En d'autres termes, la plaque 32 et les vis 35 ne font pas saillie au-dessus de la portion de la face interne 9 qui contourne la cavité 37. Cela permet au pied de prendre place dans la chaussure sans aucune gêne, pour un meilleur confort d'utilisation.With the help of Figures 5 and 6 it can be seen that, in the metatarsal zone 13, the base 3 has a cavity 37 open on the side of the inner face 9. This cavity accommodates the plate 32 of the wedge 31, as well as the heads 36 of the screws 35. the plate and the heads of the screws are flush with the remainder of the inner face 9 of the base 3. In other words, the plate 32 and the screws 35 do not protrude above the portion of the inner face 9 which circumvents the cavity 37. This allows the foot to take place in the shoe without any discomfort, for a better comfort of use.

De manière non obligatoire, toujours en rapport avec les figures 5 et 6, on précise que la chaussure 1 comprend un chausson 38. Là encore il s'agit d'un élément bien connu de l'homme du métier, et non détaillé ici. Le chausson a par exemple vocation à apporter un certain niveau de confort à l'utilisateur. Il peut être monté dans la chaussure 1 de façon amovible, ce qui facilite son changement ou son retrait provisoire, par exemple pour accéder aux vis 35. Par cet accès il est possible d'agir sur les vis, par exemple de les desserrer puis de les resserrer, afin d'ajuster la position de la cale 31 par rapport à la base 3. L'accès est d'autant plus facile que l'ouverture supérieure 22 de la chaussure 1 s'étend jusqu'à la zone de métatarse 13. Parce que la plaque 32 et les têtes 36 des vis 35 prennent place dans la cavité 37, la mise en place et le retrait du chausson se font librement, sans gêne.Not obligatory, always in relation to the Figures 5 and 6 , it is specified that the shoe 1 comprises a shoe 38. Here again it is an element well known to those skilled in the art, and not detailed here. The slipper is for example intended to provide a certain level of comfort to the user. It can be mounted in the boot 1 removably, which facilitates its change or temporary withdrawal, for example to access the screws 35. By this access it is possible to act on the screws, for example to loosen and then to tighten them, in order to adjust the position of the wedge 31 relative to the base 3. The access is even easier than the upper opening 22 of the shoe 1 extends to the metatarsal area 13 Because the plate 32 and the heads 36 of the screws 35 take place in the cavity 37, the establishment and removal of the liner are done freely without discomfort.

On observe encore que, dans la zone de métatarse 13, la face de coopération 8 présente une courbure convexe en direction longitudinale et une courbure convexe en direction transversale. En d'autres termes, la face de coopération 8 présente un bossage convexe au niveau de la zone de métatarse. On peut dire aussi que la base 3 est convexe dans toutes les directions, du côté de la face de coopération 8, dans la zone de métatarse 13. Cela permet de positionner la chaussure 1 sur la pédale 2 par des mouvements avec trois degrés de liberté en rotation, dans l'esprit d'une liaison de type rotule. Un avantage qui en découle est la possibilité de régler la position de la chaussure 1, sur la pédale, d'une façon qui convient à une majorité d'utilisateurs, voire à tous.It is also observed that, in the metatarsal zone 13, the cooperation face 8 has a convex curvature in the longitudinal direction and a convex curvature in the transverse direction. In other words, the cooperation face 8 has a convex boss at the metatarsal area. It can also be said that the base 3 is convex in all directions, on the side of the cooperation face 8, in the metatarsal area 13. This makes it possible to position the shoe 1 on the pedal 2 by movements with three degrees of freedom in rotation, in the spirit of a ball-type connection. An advantage that arises is the ability to adjust the position of the shoe 1 on the pedal, in a manner that suits a majority of users, or all.

A titre d'exemple non limitatif, la face de coopération 8 présente un bossage sphérique au niveau de la zone de métatarse. En d'autres termes, le bossage est circulaire dans toutes les directions, notamment en direction longitudinale et en direction transversale. On peut dire encore que dans ce cas le bossage est une portion de sphère. Le rayon de courbure est constant, et il est le même dans toutes les directions.By way of nonlimiting example, the cooperation face 8 has a spherical boss at the level of the metatarsal area. In other words, the boss is circular in all directions, especially in the longitudinal direction and in the transverse direction. We can still say that in this case the boss is a portion of sphere. The radius of curvature is constant, and it is the same in all directions.

Alternativement, en tant qu'autre exemple non limitatif, le rayon de courbure varie soit dans une direction, soit dans plusieurs directions, ou encore dans toutes les directions.Alternatively, as another nonlimiting example, the radius of curvature varies in one direction, in several directions, or in all directions.

Sur le plan des valeurs, le ou les rayons de courbure RL1 de la convexité longitudinale, de la face de coopération 8, sont compris entre 150 et 250 mm, et le ou les rayons de courbure RW1 de la convexité transversale, de la face de coopération, sont compris entre 150 et 250 mm. Ces valeurs sont données à titre d'exemples, sachant que de bons résultats ont été obtenus avec des rayons situés entre 170 et 200 mm. On peut observer en complément que les éléments d'accrochage 33, 34 de la cale 31 suivent, d'une part, la convexité longitudinale de la face de coopération 8 selon un ou des rayons de courbure RL2 et, d'autre part, la convexité transversale de la face de coopération 8 selon un ou des rayons de courbure RW2.In terms of values, the radii of curvature RL1 of the longitudinal convexity, of the cooperation face 8, are between 150 and 250 mm, and the radii or radii of curvature RW1 of the transverse convexity, of the face of cooperation, are between 150 and 250 mm. These values are given as examples, knowing that good results have been obtained with radii between 170 and 200 mm. It can be observed in addition that the fastening elements 33, 34 of the shim 31 follow, on the one hand, the longitudinal convexity of the cooperation face 8 in one or more radii of curvature RL2 and, on the other hand, the transverse convexity of the cooperation face 8 along one or more radii of curvature RW2.

Une synthèse schématique du résultat procuré par l'invention, selon la première forme de réalisation, est donnée par la figure 7. On peut simplement voir sur celle-ci la distance d mesurée entre la face inférieure P du pied et l'axe A de la pédale 2. La face inférieure du pied se situe au niveau de la face interne 9 de la base 3 dans les cas où la chaussure est dépourvue de chausson ou de semelle interne. La face inférieure du pied se situe au niveau d'une face d'un chausson ou d'une semelle interne prévue pour recevoir le pied, dans les cas où la chaussure en est pourvue. Dans toutes les configurations, la chaussure selon l'invention rapproche le pied de plusieurs millimètres en direction de l'axe de la pédale, en comparaison avec une chaussure selon l'art antérieur. Le rapprochement est égal ou supérieur à 3 mm. Par exemple il a été mesuré des distances d comprises entre 10 et 13 mm, là où l'art antérieur affiche des distances supérieures ou égales à 16 mm.A schematic summary of the result provided by the invention, according to the first embodiment, is given by the figure 7 . It can simply be seen on it the distance d measured between the lower face P of the foot and the axis A of the pedal 2. The lower face of the foot is located at the inner face 9 of the base 3 in cases where the shoe is devoid of slipper or insole. The lower face of the foot is at one side of a liner or an inner sole provided to receive the foot, in cases where the shoe is provided. In all configurations, the shoe according to the invention brings the foot several millimeters towards the axis of the pedal, in comparison with a shoe according to the prior art. The approximation is equal to or greater than 3 mm. For example, distances of between 10 and 13 mm have been measured where the prior art displays distances greater than or equal to 16 mm.

Les autres formes de réalisation de l'invention sont présentées ci-après sommairement à l'aide des figures 8 à 10. Pour des raisons de commodité, ce sont surtout les différences par rapport à la première forme de réalisation qui sont mises en évidence. De plus, il est prévu d'utiliser les mêmes références pour des éléments identiques ou similaires vus dans la première forme.The other embodiments of the invention are summarized below with the aid of the Figures 8 to 10 . For reasons of convenience, it is especially the differences with respect to the first embodiment that are highlighted. In addition, it is intended to use the same references for identical or similar elements seen in the first form.

Ainsi pour la deuxième forme, selon la figure 8, on retrouve une chaussure 1, avec sa base 3 et les bords 6, 7, ses parois latérale 15 et médiale 16, la cale 31 et le chausson 38.So for the second form, according to the figure 8 , there is a shoe 1, with its base 3 and the edges 6, 7, its side walls 15 and medial 16, the wedge 31 and the shoe 38.

Ce qui est spécifique à la deuxième forme de réalisation, c'est la géométrie de la cale 31. Ici, les éléments d'accrochage 33, 34 suivent les convexités longitudinale et transversale pour leur solidarisation à la face de coopération 8, mais s'inscrivent dans un plan G au niveau du contact avec la pédale 2. Cette dernière, non reproduite, présente une surface plane pour l'accueil de la chaussure. Il s'agit simplement d'une variante de réalisation qui permet l'utilisation d'un vélo muni de pédales plates.What is specific to the second embodiment is the geometry of the wedge 31. Here, the fastening elements 33, 34 follow the longitudinal and transverse convexities for their attachment to the cooperation face 8, but are included in a plane G at the contact with the pedal 2. The latter, not reproduced, has a flat surface for the home of the shoe. It is simply an alternative embodiment that allows the use of a bike with flat pedals.

Pour la troisième forme de réalisation, selon la figure 9, on retrouve encore une chaussure 1, avec sa base 3 et les bords 6, 7, ses parois latérale 15 et médiale 16, la cale 31 et le chausson 38.For the third embodiment, according to the figure 9 , there is still a shoe 1, with its base 3 and the edges 6, 7, its side walls 15 and medial 16, the wedge 31 and the shoe 38.

Ce qui est spécifique à la troisième forme de réalisation c'est que, dans la zone de métatarse 13, une entretoise 41 est disposée en regard de la face de coopération 8. Plus précisément, l'entretoise est intercalée entre la base 3 et la cale 31, dans la zone de métatarse 13. Cette entretoise protège la face de coopération 8 d'éventuelles agressions mécaniques, comme des frottements ou des appuis ponctuels, qui pourraient survenir par exemple lors d'un réglage de position de la cale, lors d'un appui au sol ou sur la pédale, ou autre. L'entretoise 41 est par exemple constituée d'une feuille de matière synthétique.What is specific to the third embodiment is that, in the metatarsal area 13, a spacer 41 is arranged facing the cooperation face 8. More specifically, the spacer is interposed between the base 3 and the 31, in the metatarsal area 13. This spacer protects the cooperation face 8 possible mechanical aggression, such as friction or punctures, which could occur for example when adjusting the position of the hold, when pressing the ground or on the pedal, or other. The spacer 41 is for example made of a sheet of synthetic material.

Pour la quatrième forme de réalisation, selon la figure 10, on retrouve à nouveau une chaussure 1, avec sa base 3 et les bords 6, 7, ses parois latérale 15 et médiale 16, la cale 31 et le chausson 38.For the fourth embodiment, according to the figure 10 , there is again a shoe 1, with its base 3 and the edges 6, 7, its side walls 15 and medial 16, the wedge 31 and the shoe 38.

Ce qui est spécifique à la quatrième forme de réalisation c'est que, dans la zone de métatarse 13, la face de coopération 8 présente une courbure convexe en direction longitudinale et une courbure droite en direction transversale. Le ou les rayons de courbure de la convexité longitudinale, de la face de coopération, sont compris entre 150 et 250 mm, sachant que de bons résultats ont été obtenus pour des valeurs de rayons comprises entre 170 et 200 mm. Dans certains cas, la courbure longitudinale se fait selon un seul rayon, il n'y a pas de courbure en direction transversale, et ainsi la zone de métatarse présente en fait une portion de cylindre. Cette variante de réalisation permet l'utilisation d'un vélo muni de pédales dont une face au moins présente une concavité dont la courbure est parallèle à l'axe de la pédale.What is specific to the fourth embodiment is that, in the metatarsal area 13, the cooperation face 8 has a convex curvature in the longitudinal direction and a straight curvature in the transverse direction. The radius or radius of curvature of the longitudinal convexity, of the cooperation face, is between 150 and 250 mm, knowing that good results have been obtained for radius values of between 170 and 200 mm. In some cases, the longitudinal curvature is in a single radius, there is no curvature in the transverse direction, and so the metatarsal area actually has a portion of the cylinder. This embodiment allows the use of a bicycle with pedals, one side at least has a concavity whose curvature is parallel to the axis of the pedal.

Dans tous les cas l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In all cases the invention is made from materials and according to processing techniques known to those skilled in the art.

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.Of course, 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.

Par exemple, en parlant de la géométrie de la base 3, on peut prévoir un cas pour lequel, dans la zone de métatarse 13, la face de coopération 8 est plane. Dans ce cas, si une cale est utilisée, la face de cette dernière destinée à être solidarisée à la base 3 doit être plane.For example, speaking of the geometry of the base 3, we can provide a case for which, in the metatarsal area 13, the cooperation face 8 is flat. In this case, if a shim is used, the face of the latter intended to be secured to the base 3 must be flat.

D'une manière plus générale, on précise que les géométries de la base 3 dans la zone de métatarse 13 peuvent se poursuivre dans une zone annexe, notamment dans la zone avant 14, voire aussi dans la zone centrale 12. Cela veut dire par exemple, et de manière non limitative, que dans la zone centrale 12, dans la zone de métatarse 13 et dans la zone avant 14, la face de coopération 8 présente une courbure convexe en direction longitudinale.More generally, it is specified that the geometries of the base 3 in the metatarsal zone 13 can continue in an adjoining zone, especially in the front zone 14, or even in the central zone 12. This means, for example , and in a nonlimiting manner, that in the central zone 12, in the metatarsal zone 13 and in the front zone 14, the cooperation face 8 has a convex curvature in the longitudinal direction.

A propos des caractéristiques des matériaux, on confirme que l'on peut prévoir de faire varier l'épaisseur de la base 3 ou celle d'une ou de plusieurs parois. Par exemple, la paroi latérale 15, la paroi médiale 16, ou ces deux parois peuvent chacune présenter une épaisseur qui se réduit depuis la base 3 vers leur extrémité libre respective. Cela améliore encore l'aptitude de la chaussure au serrage du pied, tout en préservant la rigidité au niveau de la base 3.With regard to the characteristics of the materials, it is confirmed that it is possible to vary the thickness of the base 3 or that of one or more walls. For example, the side wall 15, the medial wall 16, or these two walls may each have a thickness which is reduced from the base 3 towards their respective free end. This further improves the ability of the shoe to tighten the foot, while maintaining rigidity at the base 3.
