Abstract

The shoe has an outer sole assembly (12), upper and a fastening element (25) structured and arranged to cooperate with a locking mechanism, where the locking mechanism is adapted to be affixed to a sports apparatus. A position-adjustable connection unit connects the fastening element selectively to the outer sole assembly in an adjustable manner. The fastening element includes transverse wires (26, 27) and longitudinal bars (31, 32). One of the wires is located on a side of ends (33, 35) of the bars.

Description

L'invention se rapporte à une chaussure prévue pour être retenue de manière réversible à un engin de sport, et concerne plus particulièrement une chaussure destinée à la pratique d'un sport de neige.The invention relates to a shoe intended to be retained reversibly to a sports machine, and more particularly to a shoe intended for the practice of a snow sport.

De telles chaussures peuvent être utilisées dans des domaines tels que le ski de fond ou de télémark, la raquette à neige, le patin à roues, le cyclisme, ou autre.Such shoes can be used in areas such as cross-country skiing or telemark skiing, snowshoeing, rollerblading, cycling, or the like.

Une chaussure de cette famille comprend un semelage externe, une tige et un élément d'accrochage, ce dernier étant prévu pour coopérer avec un mécanisme de verrouillage lui-même prévu pour être assujetti à l'engin. L'élément d'accrochage et le mécanisme de verrouillage constituent un moyen d'accrochage qui, très souvent, est prévu pour retenir la chaussure sur l'engin de manière réversible.A shoe of this family comprises an outer sole, a rod and an attachment element, the latter being provided to cooperate with a locking mechanism itself intended to be subject to the machine. The hooking element and the locking mechanism are a hooking means which, very often, is provided to hold the boot on the machine in a reversible manner.

Par exemple, dans le domaine du ski de fond, il est habituel que chaque mécanisme de verrouillage puisse soit retenir une chaussure, soit la libérer. Cela permet au choix de conduire les skis ou de marcher.For example, in the field of cross-country skiing, it is usual for each locking mechanism to either hold a shoe or release it. This allows the choice to drive the skis or walk.

Il est également habituel de permettre à l'arrière de la chaussure, c'est-à-dire au talon, d'alternativement s'éloigner puis se rapprocher du ski selon des cycles répétés. Cela facilite la conduite, notamment parce qu'un utilisateur peut effectuer des mouvements plus libres qu'il ne le pourrait avec les talons immobilisés. En termes de structure l'élément d'accrochage comprend généralement un fil rigide, dont une portion est orientée parallèlement au semelage externe et selon une direction transversale de celui-ci. La portion est à l'écart du semelage, et présente généralement une section circulaire prévue pour coopérer avec des mâchoires du mécanisme de verrouillage, à la manière d'une charnière. Il est par exemple prévu deux mâchoires qui peuvent être rapprochées ou éloignées l'une de l'autre, pour retenir ou libérer l'élément d'accrochage. En conséquence c'est la chaussure qui est tantôt retenue tantôt libérée. Cet agencement, largement répandu, est satisfaisant notamment parce qu'il est simple, facile à fabriquer, et facile à utiliser. En effet, l'élément d'accrochage est solidarisé au semelage externe de façon à ne pas gêner la marche.It is also usual to allow the back of the shoe, that is to say the heel, to alternately move away and then approach the ski in repeated cycles. This makes driving easier, especially because a user can move more freely than he could with the stubborn heels. In terms of structure, the fastening element generally comprises a rigid wire, a portion of which is oriented parallel to the outer sole and in a transverse direction thereof. The portion is away from the sole, and generally has a circular section provided to cooperate with the jaws of the locking mechanism, in the manner of a hinge. For example, there are two jaws that can be moved closer together or away from one another to retain or release the fastener. As a result it is the shoe that is sometimes held sometimes released. This arrangement, widely used, is satisfactory in particular because it is simple, easy to manufacture, and easy to use. Indeed, the fastening element is secured to the outer sole so as not to hinder walking.

Cependant, quelques inconvénients liés à cet agencement ont pu être observés.However, some disadvantages related to this arrangement could be observed.

Tout d'abord, parce qu'il tourne dans les mâchoires, l'élément d'accrochage s'use. En conséquence le guidage en rotation de la chaussure, par rapport au mécanisme de verrouillage, se fait avec un jeu qui augmente proportionnellement au nombre de cycles effectués. Lorsque le jeu devient trop grand la précision de conduite est réduite, et les efforts à fournir sont plus grands. En effet, les frottements de l'élément d'accrochage dans les mâchoires augmentent. Cela oblige à changer la chaussure, sachant que si l'élément d'accrochage est usé, le reste de la chaussure ne l'est généralement pas. On peut dire que l'usure de l'élément d'accrochage réduit la durée de vie de la chaussure. Cela est dommage dans la mesure où l'utilisateur souhaite souvent garder une chaussure qui s'est adaptée à son pied.First, because it rotates in the jaws, the attachment element wears out. Consequently, the rotational guidance of the shoe, with respect to the locking mechanism, is done with a game that increases proportionally to the number of cycles performed. When the game becomes too big the driving accuracy is reduced, and the efforts to be provided are greater. Indeed, the friction of the fastening element in the jaws increases. This requires changing the shoe, knowing that if the attachment element is worn, the rest of the shoe is usually not. It can be said that the wear of the fastening element reduces the life of the shoe. This is a pity in that the user often wants to keep a shoe that has adapted to his foot.

Un autre inconvénient lié à l'agencement de l'élément d'accrochage est la spécialisation de la chaussure. En effet la position figée de l'élément d'accrochage, par rapport au semelage, fait que la chaussure ne convient pas à tous les utilisateurs. Tous ne s'accommodent pas de la même façon de la position d'articulation de la chaussure par rapport à l'engin conduit. Certains préféreraient parfois une articulation plus avancée ou, au contraire, plus reculée. Car un écart dans un sens ou dans l'autre, même faible, change beaucoup la conduite d'un ski. On peut dire qu'une chaussure donnée satisfait une majorité d'utilisateurs sans toutefois les satisfaire tous. C'est pourquoi il arrive qu'un utilisateur n'obtienne pas un rendement maximal dans la transmission des impulsions de conduite ou dans la perception des informations sensorielles liées à la conduite.Another disadvantage related to the arrangement of the fastening element is the specialization of the shoe. Indeed the fixed position of the fastening element, compared to the sole, makes that the shoe is not suitable for all users. All do not accommodate in the same way the position of articulation of the shoe with respect to the machine driven. Some would sometimes prefer a more advanced or, on the contrary, more remote articulation. Because a gap in one direction or the other, even weak, changes the driving of a ski a lot. It can be said that a given shoe satisfies a majority of users without satisfying them all. This is why a user does not obtain a maximum yield in the transmission of driving impulses or in the perception of sensory information related to driving.

Par rapport à cela l'invention cherche à améliorer une chaussure, notamment au niveau de son semelage externe. Plus précisément l'invention veut augmenter la durée de vie de la chaussure. L'invention souhaite aussi rendre la chaussure plus polyvalente, c'est-à-dire faire en sorte de l'adapter au plus grand nombre d'utilisateurs. Notamment, il faudrait que tout utilisateur obtienne un rendement maximal dans la transmission des impulsions de conduite ou dans la perception des informations sensorielles liées à la conduite.In relation to this, the invention seeks to improve a shoe, particularly at the level of its outer sole. More specifically, the invention wants to increase the life of the shoe. The invention also wishes to make the shoe more versatile, that is to say, to make it suitable for the largest number of users. In particular, it would be necessary for any user to obtain maximum efficiency in the transmission of driving impulses or in the perception of sensory information related to driving.

Pour ce faire l'invention propose une chaussure prévue pour être retenue de manière réversible à un engin de sport, la chaussure comprenant un semelage externe, une tige et un élément d'accrochage, ce dernier étant prévu pour coopérer avec un mécanisme de verrouillage lui-même prévu pour être assujetti à l'engin.To this end, the invention proposes a boot designed to be reversibly retained by a sports machine, the boot comprising an outer sole, a rod and a fastening element, the latter being provided to cooperate with a locking mechanism. -Even planned to be subject to the craft.

La chaussure selon l'invention est caractérisée par le fait qu'elle comprend un moyen de liaison réglable en position qui relie de façon réglable l'élément d'accrochage au semelage externe.The shoe according to the invention is characterized in that it comprises a linkage means adjustable in position which adjustably connects the fastening element to the outer sole.

Il peut être prévu que le moyen de liaison réglable en position soit un moyen de liaison amovible qui relie de façon amovible l'élément d'accrochage au semelage externe.It may be provided that the positionally adjustable connecting means is a detachable connection means which removably connects the fastening element to the outer sole.

Cela signifie que l'élément d'accrochage peut être solidarisé au semelage externe, ou en être séparé, selon besoin.This means that the attachment element can be secured to the outer sole, or be separated, as needed.

Par conséquent il est possible de remplacer l'élément d'accrochage, par exemple pour pallier une usure. Cet élément est une pièce d'usure qui s'intègre dans l'ensemble beaucoup plus vaste qu'est la chaussure. Il s'ensuit que l'utilisateur peut garder une chaussure qui lui va bien, et retrouver avec elle une précision de conduite satisfaisante.Therefore it is possible to replace the attachment element, for example to overcome wear. This element is a piece of wear that fits into the much larger set that is the shoe. It follows that the user can keep a shoe that fits him well, and find with it a satisfactory driving precision.

En outre l'élément d'accrochage retiré peut être remplacé par un autre dont la structure est, au choix, identique ou différente. On peut aussi prévoir de modifier la position de l'élément d'accrochage, par exemple selon une direction longitudinale de la chaussure. Certains préfèreront une position plus avancée, d'autres une position plus reculée. Ou encore un utilisateur donné adaptera sa chaussure à un style de conduite particulier. C'est notamment intéressant en ski de fond, selon que le pas pratiqué est alternatif ou à la manière d'un patineur. Il s'ensuit que la chaussure de l'invention saura satisfaire le plus grand nombre d'utilisateurs. Chacun d'eux va obtenir un rendement maximal dans la transmission des impulsions de conduite et dans la perception des informations sensorielles liées à la conduite.In addition, the removed fastening element can be replaced by another whose structure is, as desired, identical or different. It is also possible to modify the position of the fastening element, for example in a longitudinal direction of the boot. Some will prefer a more advanced position, others a more remote position. Or a given user will adapt his shoe to a particular style of driving. This is particularly interesting in cross-country skiing, depending on whether the step practiced is alternative or in the manner of a skater. It follows that the shoe of the invention will satisfy the largest number of users. Each of them will achieve maximum efficiency in the transmission of driving impulses and in the perception of sensory information related to driving.

Pour résumer on peut dire que la chaussure de l'invention voit sa durée de vie accrue, et qu'elle optimise la conduite d'un engin de sport tel qu'un ski.To summarize, it can be said that the shoe of the invention sees its increased life, and that it optimizes the driving of a sports machine such as a ski.

Les formes de réalisation de l'invention qui vont être décrites après concernent plus spécialement des chaussures pour la pratique du ski de fond, de la randonnée à ski, ou du télémark. 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 shoes for cross-country skiing, ski touring, or telemark. However, the invention applies to other fields such as those mentioned before.

C'est à l'aide des figures 1 à 4 qu'est présentée la première forme. Tout d'abord, sur la figure 1, on peut voir un ensemble qui comprend une chaussure 1, un ski 2 et un dispositif de retenue 3 de la chaussure sur le ski.It is with the help of Figures 1 to 4 that is presented the first form. First, on the figure 1 , we can see a set that includes a shoe 1, a ski 2 and a retaining device 3 of the boot on the ski.

De manière connue le dispositif de retenue 3 comprend une embase 4, laquelle porte un mécanisme de verrouillage réversible 5, un mécanisme de rappel élastique 6, et une arête de guidage longitudinal 7. Il est par exemple possible de solidariser le mécanisme de verrouillage 5, le mécanisme de rappel 6 et l'arête de guidage 7 à l'embase 4, pour que le dispositif de retenue 3 soit cohérent. Le dispositif de retenue 3 et le ski 2 ne sont pas plus décrits ici, car bien connus de l'homme du métier.In known manner the retaining device 3 comprises a base 4, which carries a reversible locking mechanism 5, an elastic return mechanism 6, and a longitudinal guide edge 7. It is for example possible to secure the locking mechanism 5, the return mechanism 6 and the guide edge 7 at the base 4, so that the retaining device 3 is coherent. The retainer 3 and the ski 2 are not further described here, as well known to those skilled in the art.

En ce qui concerne la chaussure 1, celle-ci comprend un semelage externe 12 et une tige 13. Le semelage externe 12 peut comprendre une partie, deux parties, ou plus. La chaussure 1 s'étend en longueur depuis une extrémité arrière ou talon 14 jusqu'à une extrémité avant ou pointe 15, et en largeur entre un côté latéral 16 et un côté médial 17. On observe que par corollaire le semelage externe 12 s'étend en longueur depuis le talon 14 jusqu'à la pointe 15, et en largeur entre le côté latéral 16 et le côté médial 17. Le semelage 12 s'étend aussi en hauteur, ou en épaisseur, entre une face libre 18 et une face de liaison 19. Bien entendu la face libre 18 est destinée à prendre contact avec le sol, le dispositif de retenue 3, ou encore le ski 2. La face de liaison 19, quant à elle, sert à solidariser le semelage 12 au reste de la chaussure, par exemple par collage.With regard to the shoe 1, it comprises an outer sole 12 and a rod 13. The outer sole 12 may comprise one part, two parts, or more. The shoe 1 extends in length from a rear end or heel 14 to a front end or tip 15, and in width between a lateral side 16 and a medial side 17. It is observed that by corollary the outer sole 12 is s' extends in length from the heel 14 to the tip 15, and in width between the lateral side 16 and the medial side 17. The sole 12 also extends in height, or in thickness, between a free face 18 and a face link 19. Of course the free face 18 is intended to make contact with the ground, the retaining device 3, or the ski 2. The connecting face 19, for its part, serves to secure the sole assembly 12 to the rest of the shoe, for example by gluing.

Telle que représentée la tige 13 comprend une portion basse 20, prévue pour entourer le pied, ainsi qu'une portion haute 21, prévue pour entourer la cheville. Cependant, il pourrait être envisagé une tige comprenant seulement la portion basse.As shown the rod 13 comprises a lower portion 20, provided to surround the foot, and an upper portion 21, provided to surround the ankle. However, it could be considered a rod comprising only the lower portion.

La chaussure 1 comprend encore un élément d'accrochage 25, ce dernier étant prévu pour coopérer avec le dispositif de retenue 3 lui-même prévu pour être assujetti au ski 2. Plus précisément l'élément d'accrochage 25 coopère avec le mécanisme de verrouillage 5 et, selon la première forme de réalisation décrite, avec le mécanisme de rappel élastique 6.The boot 1 further comprises a fastening element 25, the latter being provided to cooperate with the retaining device 3 itself intended to be subject to the ski 2. More precisely the fastening element 25 cooperates with the locking mechanism 5 and, according to the first embodiment described, with the elastic return mechanism 6.

Selon l'invention, comme on le comprend à l'aide de l'ensemble des figures 1 à 4, la chaussure 1 comprend un moyen de liaison amovible qui relie de façon amovible l'élément d'accrochage 25 au semelage externe 12. Le moyen de liaison permet au choix de solidariser l'élément d'accrochage 25 au semelage externe 12, ou de l'en séparer. Il est donc possible à volonté de démonter et remonter l'élément d'accrochage, pour le remplacer ou pour modifier sa position par rapport au semelage 12. Cela permet de gérer les problèmes d'usure, en remplaçant un ancien élément 25 par un neuf. Cela permet aussi, comme on le verra mieux après, de modifier l'interaction entre la chaussure et le ski. La modification de la position de l'élément d'accrochage 25 change l'effet des appuis ou des impulsions liés à la conduite du ski. Cela permet à l'utilisateur de mieux adapter la chaussure à ses besoins.According to the invention, as is understood by means of the set of Figures 1 to 4 , the shoe 1 comprises a removable connection means which removably connects the fastening element 25 to the outer sole 12. The connecting means allows the choice of securing the fastening element 25 to the outer sole 12, or of to separate it. It is therefore possible at will to disassemble and reassemble the attachment element, to replace it or to change its position relative to the sole 12. This makes it possible to manage the wear problems, by replacing an old element 25 with a new one. . It also allows, as will be seen later, to modify the interaction between the shoe and the ski. The modification of the position of the attachment element 25 changes the effect of the supports or pulses related to the driving of the ski. This allows the user to better adapt the shoe to his needs.

Selon la première forme de réalisation décrite, d'un point de vue structurel, l'élément d'accrochage 25 comprend un premier fil transversal 26. Celui-ci 26 est prévu, selon la disposition de l'élément d'accrochage 25 sur le semelage externe 12, soit pour être retenu de manière amovible par le mécanisme de verrouillage 5, soit pour être sollicité élastiquement par le mécanisme de rappel 6. Dans ce cas la sollicitation ramène le semelage externe 12 vers l'embase 4, c'est-à-dire aussi vers le ski 2.According to the first embodiment described, from a structural point of view, the fastening element 25 comprises a first transverse wire 26. The latter 26 is provided, according to the arrangement of the fastening element 25 on the external sole 12, either to be removably retained by the locking mechanism 5, or to be biased elastically by the return mechanism 6. In this case the bias returns the outer sole 12 to the base 4, that is, to say also to the ski 2.

Dans le même esprit l'élément d'accrochage 25 comprend un deuxième fil transversal 27. Là encore, selon la disposition de l'élément d'accrochage 25 sur le semelage externe 12, le deuxième fil 27 est soit retenu de manière amovible par le mécanisme de verrouillage 5, soit sollicité élastiquement par le mécanisme de rappel 6.In the same spirit, the hooking element 25 comprises a second transverse wire 27. Again, according to the arrangement of the fastening element 25 on the outer sole 12, the second wire 27 is either detachably retained by the locking mechanism 5, is biased elastically by the return mechanism 6.

Il va de soi que chacun des fils 26, 27 est orienté parallèlement au semelage externe 12, dans une direction qui s'étend de l'un des côtés latéral 16 ou médial 17 vers l'autre de ces côtés. Les fils 26, 27 sont écartés du semelage externe 12, d'une distance comprise entre 1 et 25mm, sachant que des distances de 5 à 15mm ont donné de bons résultats.It goes without saying that each of the son 26, 27 is oriented parallel to the outer sole 12, in a direction that extends from one of the lateral side 16 or medial 17 to the other of these sides. The son 26, 27 are spaced apart from the outer sole 12, a distance of between 1 and 25mm, knowing that distances of 5 to 15mm have given good results.

L'écart longitudinal entre les fils est compris entre 30 et 60mm, et est par exemple de 50mm.The longitudinal distance between the wires is between 30 and 60 mm, and is for example 50 mm.

Chaque fil 26, 27 est constitué d'une matière métallique, comme un acier ou tout matériau équivalent, et présente une section transversale circulaire. Cela permet une meilleure coopération avec le mécanisme de verrouillage 5 ou le mécanisme de rappel 6.Each wire 26, 27 is made of a metallic material, such as steel or any equivalent material, and has a circular cross section. This allows a better cooperation with the locking mechanism 5 or the return mechanism 6.

On observe encore que l'élément d'accrochage 25 comprend une première barre longitudinale 31 et une deuxième barre longitudinale 32, toutes deux prévues pour prendre appui sur le semelage externe 12. La première barre 31 s'étend longitudinalement depuis une première extrémité 33 jusqu'à une deuxième extrémité 34, et la deuxième barre 32 s'étend longitudinalement depuis une première extrémité 35 jusqu'à une deuxième extrémité 36. Il est par exemple prévu que les premières extrémités 33, 35 et les deuxièmes extrémités 34, 36 des barres soient respectivement en regard les unes des autres transversalement. Ainsi l'élément d'accrochage 25 présente une symétrie transversale qui facilite une interversion de son sens de montage, comme on le verra mieux après.It is also observed that the attachment element 25 comprises a first longitudinal bar 31 and a second longitudinal bar 32, both provided to bear on the outer sole 12. The first bar 31 extends longitudinally from a first end 33 at a second end 34, and the second bar 32 extends longitudinally from a first end 35 to a second end 36. It is for example provided that the first ends 33, 35 and the second ends 34, 36 of the bars respectively facing each other transversely. Thus the fastening element 25 has a transverse symmetry which facilitates a reversal of its mounting direction, as will be seen later.

Chaque barre 31, 32 est constituée d'une ou plusieurs matières synthétiques, comme du plastique, du caoutchouc, ou autre.Each bar 31, 32 is made of one or more synthetic materials, such as plastic, rubber, or the like.

Il est par exemple prévu que les premier 26 et deuxième 27 fils soient encastrés dans les barres 31, 32, ce qui donne sa cohésion à l'élément d'accrochage 25. On pourrait dire au final que ce dernier 25 comprend deux fils 26, 27 transversaux et deux barres 31, 32 longitudinales, ces parties formant une pièce monobloc. L'élément d'accrochage 25 est donc une pièce facile à manipuler.It is for example provided that the first 26 and second 27 son are embedded in the bars 31, 32, which gives cohesion to the hooking element 25. It could be said in the end that the latter 25 comprises two son 26, 27 transverse and two bars 31, 32 longitudinal, these parts forming a single piece. The attachment element 25 is therefore an easy to handle part.

On remarque que le premier fil 26 est situé du côté des premières extrémités 33, 35 respectives des première 31 et deuxième 32 barres. Dans le même esprit le deuxième fil 27 est situé du côté des deuxièmes extrémités 34, 36 respectives des première 31 et deuxième 32 barres. Il s'ensuit que l'un des fils 26, 27 se situe à hauteur des orteils lorsque l'élément d'accrochage 25 est en place sur le semelage 12 et que la chaussure est portée par l'utilisateur, tandis que l'autre des fils 26, 27 se situe à la limite entre les orteils et le métatarse, voire à hauteur du métatarse. Cette disposition facilite la coopération de la chaussure 1 avec le dispositif de retenue 3, par une articulation au niveau des orteils et un rappel élastique au niveau du métatarse. Le talon peut se soulever alternativement, par rapport au ski, pour une conduite efficace.Note that the first wire 26 is located on the side of the respective first ends 33, 35 of the first 31 and second 32 bars. In the same spirit the second wire 27 is located on the side of the respective second ends 34, 36 of the first 31 and second 32 bars. It follows that one of the son 26, 27 is at the toe height when the hooking element 25 is in place on the sole 12 and the shoe is worn by the user, while the other son 26, 27 is at the limit between the toes and the metatarsal, even at the height of the metatarsal. This arrangement facilitates the cooperation of the shoe 1 with the retaining device 3, by a joint at the toes and an elastic return at the metatarsal level. The heel can be raised alternately, relative to the ski, for efficient riding.

Selon la première forme de réalisation de l'invention, la chaussure 1 comprend un moyen de positionnement de l'élément d'accrochage 25 sur le semelage externe 12 selon deux positions inversées l'une par rapport à l'autre, une première position pour laquelle une première extrémité 41 de l'élément d'accrochage 25 est tournée vers l'extrémité avant 15 de la chaussure 1, et une deuxième position pour laquelle une deuxième extrémité 42 de l'élément d'accrochage 25 est tournée vers l'extrémité avant 15 de la chaussure 1. En pratique la première extrémité 41 de l'élément d'accrochage 25 est délimitée par les premières extrémités 33, 35 des barres 31, 32. Par analogie la deuxième extrémité 42 est délimitée par les deuxièmes extrémités 34, 36 des barres 31, 32.According to the first embodiment of the invention, the shoe 1 comprises a positioning means of the fastening element 25 on the outer sole 12 in two positions reversed with respect to each other, a first position for which a first end 41 of the fastening element 25 is turned towards the front end 15 of the boot 1, and a second position for which a second end 42 of the fastening element 25 is turned towards the end In practice, the first end 41 of the fastening element 25 is delimited by the first ends 33, 35 of the bars 31, 32. By analogy, the second end 42 is delimited by the second ends 34, 36 of the bars 31, 32.

Bien entendu, l'agencement ci-dessus présenté permet d'intervertir la position des fils 26, 27 le long du semelage externe 12. Cela permet de modifier le rôle de chaque fil 26, 27, dans le sens où chacun d'eux peut, au choix, coopérer avec le mécanisme de verrouillage 5 ou avec le mécanisme de rappel élastique 6. Il est par exemple possible de composer avec des différences d'usure des fils.Of course, the arrangement presented above makes it possible to invert the position of the wires 26, 27 along the outer sole 12. This makes it possible to modify the role of each wire 26, 27, in the sense that each of them can optionally, cooperate with the locking mechanism 5 or with the elastic return mechanism 6. It is for example possible to deal with differences in wear of the son.

De manière non limitative, selon la première forme de réalisation de l'invention, le moyen de positionnement ci-avant évoqué comprend deux tétons 43, 44 issus de l'élément d'accrochage 25, et présente deux orifices 45, 46 ménagés dans le semelage externe 12 pour l'accueil des tétons 43, 44, les tétons 43, 44 et les orifices 45, 46 étant respectivement en vis-à-vis transversalement. De manière plus précise, un premier tétons 43 est issu de la première barre 31, tandis que le deuxième tétons 44 est issu de la deuxième barre 32. Cela facilite la mise en place de l'élément d'accrochage 25 sur le semelage 12, dans l'une ou l'autre des positions évoquées au préalable.In a nonlimiting manner, according to the first embodiment of the invention, the aforementioned positioning means comprises two pins 43, 44 coming from the fastening element 25, and has two orifices 45, 46 formed in the external sole 12 for receiving the pins 43, 44, the pins 43, 44 and the orifices 45, 46 are respectively vis-à-vis transversely. More specifically, a first stud 43 is derived from the first bar 31, while the second stud 44 comes from the second bar 32. This facilitates the introduction of the fastening element 25 on the sole 12, in any of the positions mentioned above.

Pour des facilités de fabrication, les tétons 43, 44 et les orifices 45, 46 présentent des sections circulaires, sans toutefois que cela ne soit obligatoire.For ease of manufacture, the pins 43, 44 and the orifices 45, 46 have circular sections, but this is not mandatory.

Il est prévu que la distance d1 entre le premier fil 26 et les tétons 43, 44 soit différente de la distance d2 entre le deuxième fil 27 et les tétons 43, 44. Ainsi l'inversion du sens de montage de l'élément d'accrochage 25 sur le semelage 12 modifie la distance entre un fil 26, 27 donné et l'extrémité avant 15 de la chaussure 1. En d'autres termes, selon le sens de montage de l'élément d'accrochage 25, les fils 26, 27 sont plus ou moins proches de l'extrémité avant 15. Il s'ensuit que l'utilisateur peut choisir l'une ou l'autre des deux positions des fils 26, 27, dans l'idée d'adapter la chaussure 1 à son style de conduite. Il va avantageusement optimiser sa conduite.It is expected that the distance d1 between the first wire 26 and the pins 43, 44 is different from the distance d2 between the second wire 27 and the pins 43, 44. Thus the reversal of the mounting direction of the element of fastening 25 on the sole 12 changes the distance between a given wire 26, 27 and the front end 15 of the boot 1. In other words, depending on the mounting direction of the fastening element 25, the wires 26 , 27 are more or less close to the front end 15. It follows that the user can choose one or other of the two positions of the son 26, 27, in the idea of adapting the shoe 1 to his driving style. It will advantageously optimize its driving.

En complément on observe que le moyen de liaison amovible, qui relie l'élément d'accrochage 25 au semelage externe 12, comprend des vis 47 qui coopèrent avec l'élément d'accrochage 25 et des orifices filetés 48 du semelage externe 12. Ces vis 47 sont par exemple au nombre de quatre, même si une seule d'entre-elles est représentée. Le nombre d'orifices filetés est ici aussi de quatre. Cela permet d'exercer des efforts de serrage à proximité des fils 26, 27. Un avantage qui en découle est une transmission plus précise des informations sensorielles.In addition, it is observed that the detachable connection means, which connects the fastening element 25 to the outer sole assembly 12, comprises screws 47 which cooperate with the fastening element 25 and threaded orifices 48 of the outer sole 12. These There are, for example, four screws 47, even if only one of them is represented. The number of threaded holes is here also four. This makes it possible to exert clamping forces near the wires 26, 27. A benefit that arises is a more precise transmission of the sensory information.

Les autres formes de réalisation sont présentées ci-après à l'aide des figures 5 à 15. Pour des raisons de commodité, les éléments communs avec la première forme sont désignés par les mêmes références. Ainsi seules les différences sont mises en évidence.The other embodiments are presented below using the Figures 5 to 15 . For the sake of convenience, the elements common with the first form are designated by the same references. Thus only the differences are highlighted.

On retrouve donc pour la deuxième forme, selon les figures 5 à 7, un semelage externe 12 avec ses extrémités arrière 14 et avant 15, ses côtés latéral 16 et médial 17, et ses faces libre 18 et de liaison 19. On retrouve également un élément d'accrochage 25 avec ses premier 26 et deuxième 27 fils, ainsi que ses première 31 et deuxième 32 barres longitudinales.So we find for the second form, according to the Figures 5 to 7 , an outer sole 12 with its rear ends 14 and 15 before, its lateral sides 16 and medial 17, and its free faces 18 and connecting 19. There is also a fastening element 25 with its first 26 and second 27 son, as well as its first 31 and second 32 longitudinal bars.

Ce qui est spécifique à la deuxième forme de réalisation, c'est la façon dont l'élément d'accrochage 25 est mis en place sur le semelage 12. Ici la chaussure 1 comprend un moyen de positionnement, de l'élément d'accrochage 25 sur le semelage externe 12, par un réglage discret sur au moins deux positions, une première position pour laquelle une première extrémité 41 de l'élément d'accrochage 25 est située à une première distance de l'extrémité avant 15 de la chaussure, et une deuxième position pour laquelle la première extrémité 41 de l'élément d'accrochage 25 est située à une deuxième distance de l'extrémité avant 15 de la chaussure. Il s'agit en fait d'avancer ou de reculer l'élément d'accrochage 25 selon besoin, pour obtenir les mêmes effets qu'avec la première forme de réalisation.What is specific to the second embodiment is the manner in which the fastening element 25 is placed on the sole 12. Here the boot 1 comprises a positioning means, the fastening element 25 on the outer sole 12, by a discrete adjustment on at least two positions, a first position for which a first end 41 of the fastening element 25 is located at a first distance from the front end 15 of the shoe, and a second position for which the first end 41 of the hooking element 25 is located at a second distance from the front end 15 of the boot. This is actually to advance or retreat the hooking element 25 as needed, to achieve the same effects as the first embodiment.

Toujours selon la deuxième forme, le moyen de positionnement comprend deux tétons 43, 44 issus de l'élément d'accrochage 25, et présente au moins quatre orifices 61, 62, 63, 64 ménagés dans le semelage externe 12 pour l'accueil des tétons 43, 44, les tétons et les orifices étant respectivement en vis-à-vis par deux transversalement. Plus précisément les deux tétons 43, 44 peuvent au choix prendre place respectivement dans deux orifices 61, 62 éloignés de l'extrémités avant 15 du semelage 12, ou dans deux orifices 63, 64 plus rapprochés de l'extrémité. On obtient donc un réglage longitudinal discret à deux positions.Still according to the second form, the positioning means comprises two pins 43, 44 coming from the fastening element 25, and has at least four holes 61, 62, 63, 64 formed in the outer sole 12 for the reception of the nipples 43, 44, the nipples and the orifices being respectively vis-à-vis by two transversely. More precisely, the two studs 43, 44 may optionally take place respectively in two orifices 61, 62 remote from the front ends 15 of the sole assembly 12, or in two orifices 63, 64 closer to the end. A discrete longitudinal adjustment with two positions is thus obtained.

Bien entendu, il peut alternativement être prévu un nombre de positions supérieur à deux, par exemple trois, quatre, ou cinq.Of course, it may alternatively be provided a number of positions greater than two, for example three, four, or five.

On observe que, par corollaire, le moyen de liaison amovible, qui relie l'élément d'accrochage 25 au semelage externe 12, comprend des vis 70 qui coopèrent avec l'élément d'accrochage et des orifices filetés 71, 72, 73, 74, 75, 76, 77, 78 du semelage externe 12, le nombre d'orifices filetés étant supérieur au nombre de vis. Il est par exemple ici prévu huit orifices filetés 71 à 78, en vis-à-vis deux par deux transversalement, en corrélation avec les quatre orifices 61 à 64 pour l'accueil des tétons 43, 44. De manière non limitative, les orifices 61 à 64 d'accueil des tétons et les orifices filetés 71 à 78 d'accueil des vis sont disposés en deux rangées longitudinales, c'est-à-dire parallèles entre-elles et en vis-à-vis transversalement. Cela confère à la chaussure 1 une architecture simple pour régler la position longitudinale de l'élément d'accrochage 25.It can be observed that, by corollary, the detachable connection means, which connects the fastening element 25 to the outer sole assembly 12, comprises screws 70 which cooperate with the fastening element and threaded holes 71, 72, 73, 74, 75, 76, 77, 78 of the outer sole 12, the number of threaded orifices being greater than the number of screws. For example, eight threaded orifices 71 to 78 are provided, facing each other two by two transversely, in correlation with the four orifices 61 to 64 for receiving the nipples 43, 44. In a non-limiting manner, the orifices 61 to 64 home nipples and the threaded holes 71 to 78 of the screws are arranged in two longitudinal rows, that is to say parallel to each other and vis-à-vis transversely. This gives the boot 1 a simple architecture for adjusting the longitudinal position of the fastening element 25.

La troisième forme de réalisation de l'invention est présentée maintenant à l'aide des figures 8 à 13. On retrouve encore un semelage externe 12 avec ses extrémités arrière 14 et avant 15, ses côtés latéral 16 et médial 17, et ses faces libre 18 et de liaison 19. On retrouve également un élément d'accrochage 25 avec ses premier 26 et deuxième 27 fils, ainsi que ses première 31 et deuxième 32 barres longitudinales.The third embodiment of the invention is now presented with the help of Figures 8 to 13 . We still find an outer sole 12 with its rear ends 14 and 15 before, its lateral sides 16 and medial 17, and its free faces 18 and 19 link. also a fastening element 25 with its first 26 and second 27 son, and its first 31 and second 32 longitudinal bars.

Ce qui est spécifique à la troisième forme de réalisation, c'est encore la façon dont l'élément d'accrochage 25 est mis en place sur le semelage 12. Ici la chaussure 1 comprend un moyen de positionnement, de l'élément d'accrochage 25 sur le semelage externe 12, par un réglage continu sur une plage nominale, le déplacement de l'élément d'accrochage 25 par rapport au semelage externe 12 se faisant longitudinalement. Cette disposition augmente les possibilités de réglage de la position de l'élément d'accrochage 25. Le réglage se fait bien sûr, au choix, pour approcher l'élément d'accrochage de l'extrémité avant 15 de la chaussure ou, à l'inverse, l'en éloigner.What is specific to the third embodiment is still the way the fastening element 25 is placed on the sole 12. Here the shoe 1 comprises a positioning means, the element of hooking 25 on the outer sole 12, by a continuous adjustment over a nominal range, the displacement of the fastening element 25 relative to the outer sole 12 is longitudinally. This arrangement increases the possibilities of adjusting the position of the fastening element 25. Adjustment is of course, optionally, to approach the fastening element of the front end 15 of the shoe or, at the 'inverse, move away from it.

De manière non limitative, le moyen de positionnement comprend une glissière 91 et un rail 92. Par exemple la glissière 91 est associée à l'élément d'accrochage 25, et le rail 92 est associé au semelage externe 12. Cette disposition permet la mise en place de l'élément d'accrochage 25 sur le semelage externe 12 par coulissement, dans le sens de la longueur de la chaussure 1.In a nonlimiting manner, the positioning means comprises a slideway 91 and a rail 92. For example, the slideway 91 is associated with the hooking element 25, and the rail 92 is associated with the outer sole 12. This arrangement allows the setting in place of the fastening element 25 on the outer sole 12 by sliding, in the direction of the length of the boot 1.

Comme on le comprend notamment à l'aide des figures 9 et 10, le rail 92 présente une section transversale en forme de U, avec une base 93 et des extrémités libres 94, 95 recourbées dans un sens d'élargissement. Selon la troisième forme de réalisation, le rail 92 comprend plusieurs segments distincts 96, 97, à savoir ici deux. Cependant il pourrait alternativement en comprendre un seul ou, au contraire, trois ou plus. L'avantage des deux segments 96, 97 est une coopération localisée avec les fils 26, 27, comme on le verra mieux après. Par corollaire entre les segments 96, 97 le semelage 12 garde sa souplesse, ce qui garantit un meilleur confort d'utilisation.As is understood in particular by the help of figures 9 and 10 the rail 92 has a U-shaped cross section, with a base 93 and free ends 94, 95 curved in a widening direction. According to the third embodiment, the rail 92 comprises several distinct segments 96, 97, namely here two. However, he could alternatively understand one or, on the contrary, three or more. The advantage of the two segments 96, 97 is a localized cooperation with the son 26, 27, as will be seen better later. As a corollary between the segments 96, 97 the sole 12 remains flexible, which ensures a better user comfort.

Le rail 92 est par exemple réalisé à partir d'une matière métallique, comme un acier ou tout matériau équivalent. Il 92 est solidarisé au semelage externe 12 par exemple par insertion de sa base 93 dans la matière constitutive du semelage.The rail 92 is for example made from a metal material, such as steel or any equivalent material. It 92 is secured to the outer sole 12 for example by insertion of its base 93 in the constituent material of the sole assembly.

Comme on le comprend notamment à l'aide des figures 11 et 12, la glissière 91 est réalisée par les fils 26, 27. En effet, ceux-ci sont repliés en forme de C, leurs extrémités 101, 102 étant prévues pour prendre contact avec les extrémités recourbées 94, 95 du rail 92. Bien entendu, chaque fil 26, 27 vient en contact avec l'un des segments 96, 97. La glissière 91 est elle aussi segmentée, puisque les fils sont séparés l'un de l'autre. On observe que les parties repliées 101, 102 de chaque fil 26, 27 sont partiellement noyées dans les barres 31, 32. C'est ce qui assure la cohésion de l'élément d'accrochage 25. Cette structure a le mérite de la simplicité de fabrication, dans la mesure où elle réduit le nombre de pièces nécessaires.As is understood in particular by the help of Figures 11 and 12 , the slide 91 is made by the son 26, 27. Indeed, these are folded C-shaped, their ends 101, 102 being provided to make contact with the curved ends 94, 95 of the rail 92. Of course, each wire 26, 27 comes into contact with one of the segments 96, 97. The slide 91 is also segmented, since the wires are separated from each other. It is observed that the folded portions 101, 102 of each wire 26, 27 are partially embedded in the bars 31, 32. This is what ensures the cohesion of the fastening element 25. This structure has the merit of simplicity of manufacture, insofar as it reduces the number of parts required.

Il est bien entendu prévu d'immobiliser de manière réversible la glissière 91 par rapport au rail 92. En fait, comme le montrent les figures 8, 9 et 13, le moyen de liaison amovible, qui relie l'élément d'accrochage 25 au semelage externe 12, comprend au moins une vis 105, 106 qui coopère avec une fente 107, 108 de l'élément d'accrochage 25 et un orifice fileté 109, 110 du semelage externe 12. Bien entendu chaque fente 107, 108 est parallèle au rail 92 ou à la glissière 91, pour autoriser un mouvement de l'élément d'accrochage 25 par rapport au semelage 12, mouvement qui se fait selon la longueur de la chaussure 1, sur une plage dont la longueur correspond à la longueur des fentes 107, 108. Il va de soi que ces dernières sont en vis-à-vis l'une de l'autre transversalement. A titre d'exemple, la plage longitudinale de déplacement de l'élément d'accrochage 25 par rapport au semelage 12, lorsque les vis sont en place sans être serrées, est compris entre 10 et 35mm.It is of course intended to reversibly immobilize the slide 91 relative to the rail 92. In fact, as shown by the Figures 8, 9 and 13 , the detachable connecting means, which connects the fastening element 25 to the outer soleing 12, comprises at least one screw 105, 106 which cooperates with a slot 107, 108 of the fastening element 25 and a threaded hole 109 , 110 of the outer sole 12. Of course each slot 107, 108 is parallel to the rail 92 or the slide 91, to allow a movement of the fastening element 25 relative to the sole 12, movement which is done according to the length of the boot 1, on a range whose length corresponds to the length of the slots 107, 108. It It goes without saying that the latter are facing each other transversely. For example, the longitudinal range of displacement of the fastening element 25 relative to the sole 12, when the screws are in place without being tight, is between 10 and 35mm.

La quatrième forme de réalisation est présentée maintenant à l'aide de la figure 14. Il s'agit là d'une version plus simple de l'invention. Plus précisément l'élément d'accrochage 25 comprend un fil transversal 26 unique, lequel est destiné à coopérer avec le mécanisme de verrouillage 5. Il s'ensuit que la chaussure 1 est plus libre de pivoter par rapport au ski 2, ce qui convient bien à la pratique du pas alternatif.The fourth embodiment is now presented using the figure 14 . This is a simpler version of the invention. More specifically, the attachment element 25 comprises a single transverse wire 26, which is intended to cooperate with the locking mechanism 5. It follows that the boot 1 is more free to pivot relative to the ski 2, which is suitable well to the practice of the alternative step.

On remarque en complément que le semelage externe 12 présente une rainure longitudinale centrale 121 au niveau du talon 14. Cette rainure est prévue pour coopérer avec l'arête de guidage 7 du dispositif de retenue 3. Cela guide le semelage externe 12 lors d'un mouvement de déroulement du pied, et permet des appuis transversaux lorsque le semelage 12 est à plat sur le dispositif 3.It is noted in addition that the outer sole 12 has a central longitudinal groove 121 at the heel 14. This groove is provided to cooperate with the guide edge 7 of the retaining device 3. This guides the outer sole 12 during a movement of unwinding of the foot, and allows transverse support when the sole 12 is flat on the device 3.

La cinquième forme de réalisation est présentée maintenant à l'aide de la figure 15. On voit qu'ici le semelage externe 25 présente deux rainures longitudinales 131, 132 excentrées au niveau du talon 14. Dans ce cas le semelage externe est destiné à coopérer avec un dispositif de retenue non représenté, lequel est muni de deux arêtes de guidage.The fifth embodiment is now presented using the figure 15 . It can be seen that here the outer soleing 25 has two longitudinal grooves 131, 132 eccentric at the level of the heel 14. In this case the outer sole is intended to cooperate with a not shown retaining device, which is provided with two guide edges.

Pour l'ensemble des formes de réalisation présentées, l'élément d'accrochage 25 est situé dans une zone du semelage externe prévue pour s'étendre, en partie au moins, au niveau des orteils d'un pied. C'est ce qui permet la conduite du ski avec le talon de la chaussure qui s'en sépare alternativement.For all the embodiments presented, the attachment element 25 is located in an area of the outer sole provided to extend, at least in part, at the toes of a foot. This is what allows the ski with the heel of the shoe that separates alternately.

On précise d'ailleurs que, pour faciliter ce mouvement alternatif du talon, la tige 13 est souple et, aussi, le semelage externe est souple, au moins au niveau de la zone en regard des orteils et de la jonction entre les orteils et le métatarse. On pourrait dire que le semelage externe 12 est souple selon une longueur comprise entre 5 et 45% de la longueur de la chaussure, depuis l'extrémité avant 15. Cela améliore la conduite en permettant un meilleur déroulement du pied.It is furthermore specified that, to facilitate this reciprocating movement of the heel, the stem 13 is flexible and, also, the outer sole is flexible, at least at the level of the zone facing the toes and the junction between the toes and the toe. metatarsus. It could be said that the outer sole 12 is flexible with a length of between 5 and 45% of the length of the boot, from the front end 15. This improves the conduct by allowing a better unfolding of the foot.

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.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.

Notamment on peut prévoir d'autres structures pour l'élément d'accrochage, par exemple en remplaçant les fils par des organes tels que des pattes, des crochets, ou autre.In particular one can provide other structures for the fastening element, for example by replacing the son by organs such as tabs, hooks, or other.

A propos du réglage de la position de l'élément d'accrochage 25 sur le semelage externe 12, comme c'est le cas par exemple selon la troisième forme de réalisation, il peut être prévu que l'élément d'accrochage 25 soit amovible ou, à l'inverse, qu'il ne soit pas amovible.With regard to the adjustment of the position of the fastening element 25 on the outer sole 12, as is the case for example according to the third embodiment, it can be provided that the fastening element 25 is removable. or, conversely, that it is not removable.

Lorsque l'élément d'accrochage 25 est simplement interchangeable, il peut être prévu de le remplacer par une pièce identique ou par une pièce similaire. Dans ce dernier cas, la position longitudinale du ou des fils 26, 27 est différente.When the hooking element 25 is simply interchangeable, it may be provided to replace it with an identical part or a similar part. In the latter case, the longitudinal position of the son or son 26, 27 is different.

Dans l'invention les moyens de positionnement sont actionnés à l'aide d'un outil, puisqu'ils comprennent des vis. Il est alternativement possible de prévoir des moyens de positionnement actionnés à la main, c'est-à-dire sans outil.In the invention, the positioning means are actuated by means of a tool, since they comprise screws. It is alternatively possible to provide positioning means actuated by hand, that is to say without tools.
