Description

L'invention se rapporte au domaine des articles de sport comprenant un lien de retenue ou de serrage d'un pied ou d'une chaussure. L'invention concerne un dispositif de retenue d'une chaussure sur un engin de sport.The invention relates to the field of sports articles comprising a retaining or tightening link of a foot or a shoe. The invention relates to a device for retaining a shoe on a sports machine.

De tels articles sont utilisés pour la pratique de sports divers, tels que des sports de glisse, de roulage, ou de marche. Il peut s'agir de surf sur neige ou snowboard, de ski sur neige ou sur eau, de raquette à neige, de patin à roues, de marche, ou autre.Such articles are used for the practice of various sports, such as sliding, rolling, or walking sports. It can be snowboarding or snowboarding, skiing on snow or water, snowshoeing, rollerblading, walking, or whatever.

Dans le cas d'un dispositif de retenue d'une chaussure sur une planche de snowboard, un lien comprend généralement un tronçon de couverture de la chaussure. Un mécanisme de serrage réversible permet de serrer ou de desserrer le lien. Il s'ensuit que le tronçon de couverture serre la chaussure de manière réversible.In the case of a device for retaining a boot on a snowboard, a tie generally comprises a portion of the shoe cover. A reversible clamping mechanism makes it possible to tighten or loosen the link. It follows that the cover section tightens the shoe reversibly.

Traditionnellement le tronçon de couverture comprend une armature et une gaine. L'armature confère au tronçon de couverture des propriétés mécaniques, notamment en ce qui concerne la résistance en traction longitudinale. Ainsi même si l'armature est flexible selon un axe transversal, pour épouser la forme de la chaussure, elle reste sensiblement inextensible longitudinalement. Cela permet un serrage sensiblement constant par le lien. La gaine, quant à elle, entoure l'armature pour amortir le contact du tronçon de couverture avec la chaussure. En d'autres termes une surface de la gaine s'étend entre l'armature et la chaussure pour apporter un confort lors du serrage.Traditionally the cover section includes a frame and a sheath. The reinforcement gives the cover section mechanical properties, particularly with regard to longitudinal tensile strength. Thus even if the frame is flexible along a transverse axis, to match the shape of the shoe, it remains substantially inextensible longitudinally. This allows a substantially constant tightening by the link. The sheath, meanwhile, surrounds the frame to dampen the contact of the cover section with the shoe. In other words, a surface of the sheath extends between the frame and the boot to provide comfort during tightening.

Traditionnellement la gaine est formée par un assemblage cousu de couches de tissus et de mousses de matières synthétiques. C'est pourquoi la gaine présente généralement l'aspect d'un coussin qui enveloppe l'armature. Ainsi le confort de serrage est apporté par le coussin.Traditionally, the sheath is formed by an assembly sewn of layers of fabrics and foams of synthetic materials. This is why the sheath generally has the appearance of a cushion that envelops the frame. Thus the comfort of tightening is provided by the cushion.

Le document FR-A-2853557 divulgue un lien avec un élément de confort moulé soit avec le lien de façon monobloc, soit juxtaposé.The document FR-A-2853557 discloses a link with a molded comfort element either with the link integrally or juxtaposed.

S'il permet un serrage constant et confortable de la chaussure, le tronçon de couverture présente un certain encombrement lié au nombre de couches de tissus et de mousses. Cela gêne les manipulations du lien par un utilisateur. De plus le tronçon de couverture est relativement lourd, toujours à cause du nombre de couches de tissus et de mousses. Cela accroît les gênes de manipulations.If it allows a constant and comfortable tightening of the shoe, the cover section has a certain size related to the number of layers of fabrics and foams. This hinders the manipulation of the link by a user. In addition, the cover section is relatively heavy, still because of the number of layers of fabrics and foams. This increases the handling genes.

De plus il apparaît que les contraintes liées au serrage sont concentrées dans l'armature, ce qui oblige à dimensionner celle-ci en conséquence. Cela contribue à accroître le poids du tronçon de couverture, et donc du dispositif.In addition it appears that the constraints related to the clamping are concentrated in the armature, which forces to size it accordingly. This helps to increase the weight of the cover section, and therefore the device.

En complément il apparaît que la fabrication du tronçon de couverture est longue et relativement complexe. Il est en effet nécessaire d'assembler plusieurs pièces différentes pour obtenir le coussin dans un premier temps, puis le tronçon de couverture dans un second.In addition, it appears that the manufacture of the cover section is long and relatively complex. It is indeed necessary to assemble several different pieces to get the cushion at first, then the cover section in a second.

Par rapport à cela l'invention a notamment pour but de réduire l'encombrement du tronçon de couverture, pour faciliter les manipulations d'un lien de serrage. Un autre but de l'invention est de réduire le poids du tronçon de couverture d'un lien. L'invention cherche aussi à réduire les contraintes exercées au sein de l'armature. Encore, l'invention veut simplifier et réduire le temps de fabrication du tronçon de couverture.In relation to this, one particular object of the invention is to reduce the size of the cover section, in order to facilitate the handling of a tightening link. Another object of the invention is to reduce the weight of the cover section of a link. The invention also seeks to reduce the stresses exerted within the frame. Still, the invention wants to simplify and reduce the manufacturing time of the cover section.

Pour ce faire, l'invention propose un dispositif de retenue d'une chaussure sur un engin de sport, selon la revendication 1.To do this, the invention proposes a device for retaining a boot on a sports machine, according to claim 1.

Le dispositif selon l'invention est caractérisé par le fait que l'élément de confort comprend une matière synthétique moulée sur l'armature.The device according to the invention is characterized in that the comfort element comprises a synthetic material molded on the frame.

L'élément de confort fait corps avec l'armature grâce à son surmoulage sur cette dernière. Ainsi l'élément de confort augmente la section du tronçon de couverture sollicitée en traction lors du serrage du lien. Cette section comprend à la fois l'armature et élément. Cela permet de réduire les contraintes exercées au sein de l'armature. En d'autres termes les contraintes de traction sont réparties au sein du tronçon de couverture,The comfort element is integral with the frame thanks to its overmolding on the latter. Thus the comfort element increases the section of the cover section stressed in tension when tightening the link. This section includes both the frame and element. This reduces the stresses exerted within the frame. In other words the tensile stresses are distributed within the cover section,

L'élément de confort se substitue à une housse, ce qui économise l'utilisation de couches de tissus et de mousses. Ainsi l'encombrement du tronçon de couverture est réduit. Par corollaire les manipulations du lien de serrage sont facilitées. L'absence de housse permet aussi un gain de poids pour le lien. Ce dernier est plus léger.The comfort element replaces a cover, which saves the use of layers of fabrics and foams. Thus the size of the cover section is reduced. By corollary the manipulations of the tightening link are facilitated. The absence of cover also allows a weight gain for the link. The latter is lighter.

En complément la fabrication du tronçon de couverture est plus simple et plus rapide. En effet l'adjonction de l'élément de confort par moulage, par exemple par injection, est une opération simple et rapide. De plus le tronçon fait avec deux matériaux est plus joli.In addition the manufacture of the cover section is simpler and faster. Indeed the addition of the comfort element by molding, for example by injection, is a simple and fast operation. In addition the section made with two materials is prettier.

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

Comme on le voit sur la figure 1, un article de sport 1 ou dispositif de retenue permet la retenue temporaire sur un engin 2 d'une chaussure non représentée. L'engin 2 est par exemple une planche destinée à la pratique du snowboard.As we see on the figure 1 , a sports article 1 or retainer allows the temporary retention on a machine 2 of a shoe not shown. The machine 2 is for example a board for the practice of snowboarding.

Bien entendu, bien que le dispositif 1 se rapporte plutôt au domaine du snowboard, il doit être compris qu'il s'applique aussi à d'autres domaines comme évoqués avant.Of course, although the device 1 relates rather to the field of snowboarding, it should be understood that it also applies to other areas as mentioned before.

De manière connue, le dispositif de retenue 1 comprend une embase 3 qui s'étend longitudinalement entre une extrémité arrière 4 et une extrémité avant 5.In known manner, the retaining device 1 comprises a base 3 which extends longitudinally between a rear end 4 and a front end 5.

L'embase 3 est bordée latéralement par un flasque latéral 12 et par un flasque médial 13. Chacun des flasques 12, 13 est une pièce qui forme respectivement une partie latérale ou médiale du dispositif 1 pour délimiter une zone d'accueil 14 de la chaussure. Lorsque cette dernière est en place sur le dispositif 1, les flasques 12, 13 longent la semelle latéralement. Bien entendu, il pourrait être prévu autre chose que les flasques 12, 13 pour former les parties latérale et médiale. Par exemple de simples butées latérale et médiale pourraient convenir.The base 3 is bordered laterally by a lateral flange 12 and a medial flange 13. Each of the flanges 12, 13 is a part which respectively forms a lateral or medial part of the device 1 to delimit a reception zone 14 of the shoe . When the latter is in place on the device 1, the flanges 12, 13 run along the sole laterally. Of course, it could be provided other than the flanges 12, 13 to form the lateral and medial parts. For example, simple lateral and medial abutments may be suitable.

De préférence, l'embase 3 et les flasques 12, 13 forment une pièce monobloc réalisée par exemple en matière synthétique. Cependant il pourrait être prévu que les flasques soient des pièces solidarisées à l'embase par tout moyen, tel qu'un collage, une soudure, un vissage, un emboîtement, ou autre.Preferably, the base 3 and the flanges 12, 13 form a one-piece piece made for example of synthetic material. However, it could be expected that the flanges are parts secured to the base by any means such as gluing, welding, screwing, interlocking, or other.

Le dispositif 1 comprend aussi un élément d'appui arrière 20, pour que l'utilisateur puisse prendre des appuis arrière avec le bas de jambe.The device 1 also comprises a rear support element 20, so that the user can take back supports with the lower leg.

Selon la première forme de réalisation décrite de l'invention, l'élément d'appui arrière 20 est associé aux flasques 12, 13, par exemple au moyen d'une articulation 28. Cette dernière est orientée sensiblement selon un axe transversal 29 du dispositif 1. L'articulation 28 peut comprendre tout composant tel qu'une vis, un rivet, une rondelle, un écrou, un tourillon, ou autre.According to the first described embodiment of the invention, the rear support element 20 is associated with the flanges 12, 13, for example by means of a hinge 28. The latter is oriented substantially along a transverse axis 29 of the device 1. The hinge 28 may comprise any component such as a screw, a rivet, a washer, a nut, a pin, or other.

L'articulation 28 autorise un mouvement de rapprochement de l'élément d'appui arrière 20 vers l'embase 3. Un avantage qui en découle est de faciliter le rangement.The joint 28 allows a movement of bringing the rear support member 20 towards the base 3. A benefit that arises is to facilitate storage.

Le dispositif de retenue 1 comprend aussi une butée 35 qui limite la rotation vers l'arrière de l'élément d'appui éponyme 20.The retaining device 1 also comprises a stop 35 which limits the rearward rotation of the eponymous support element 20.

il est également prévu deux liens pour retenir de façon amovible la chaussure sur l'embase 4, entre les flasques 12, 13, dans la zone d'accueil 14.two links are also provided for removably retaining the boot on the base 4, between the flanges 12, 13, in the reception zone 14.

Un premier lien 50 se situe vers l'avant, au niveau de l'articulation métatarsophalangienne quand le pied est retenu. Un deuxième lien 51 se situe vers l'arrière, au niveau du cou-de-pied quand le pied est retenu.A first link 50 is located forward, at the metatarsophalangeal joint when the foot is retained. A second link 51 is located aft, at the instep when the foot is held.

Chacun des liens 50, 51 s'étend transversalement entré les flasques 12, 13.Each of the links 50, 51 extends transversely between the flanges 12, 13.

Bien entendu, il pourrait être prévu un nombre de liens différent.Of course, there could be a different number of links.

Pour des raisons de commodité un seul des liens 50, 51 est décrit ci-après, par exemple le deuxième. Cependant il doit être compris que ce qui s'applique au deuxième 51 peut être valable pour le premier 50.For the sake of convenience only one of the links 50, 51 is described below, for example the second. However it must be understood that what applies to the second 51 may be valid for the first 50.

Comme on le comprend notamment à l'aide des figures 1 et 2, le lien 51 comprend une première portion 52, une deuxième portion 53, et un premier moyen de liaison 54 des portions.As is understood in particular by the help of figures 1 and 2 the link 51 comprises a first portion 52, a second portion 53, and a first connection means 54 of the portions.

La première portion 52 s'étend longitudinalement entre une extrémité d'attache 55 et une extrémité libre 56. L'extrémité d'attache 55 est solidarisée au flasque latéral 12 par exemple à l'aide d'une articulation 57 d'axe 58. L'articulation 57 peut comprendre tout élément tel qu'une vis, un écrou, un rivet, ou autre.The first portion 52 extends longitudinally between an attachment end 55 and a free end 56. The attachment end 55 is secured to the lateral flange 12, for example by means of a hinge 57 of axis 58. The hinge 57 may comprise any element such as a screw, a nut, a rivet, or the like.

La deuxième portion 53 quant à elle s'étend longitudinalement entre une extrémité d'attache 65 et une extrémité libre 66. L'extrémité d'attache 65 est solidarisée au flasque médial 13 par exemple à l'aide d'une articulation 67 d'axe 68. Là encore l'articulation 67 peut comprendre tout élément tel qu'une vis, un écrou, un rivet, ou autre.The second portion 53 in turn extends longitudinally between an attachment end 65 and a free end 66. The attachment end 65 is secured to the medial flange 13 for example by means of a hinge 67 of axis 68. Again the joint 67 may include any element such as a screw, a nut, a rivet, or other.

Selon la première forme de réalisation décrite, la deuxième portion 53 est réglable en longueur. Pour cela la deuxième portion 53 comprend par exemple un tronçon d'attache 69, du côté de l'extrémité d'attache 65, ainsi qu'un tronçon de couverture 70, du côté de l'extrémité libre 66. Un moyen de réglage relie l'un à l'autre les tronçons 69, 70 de manière réglable. Ce moyen comprend par exemple une liaison vis-écrou 71, mais bien entendu d'autres structures de liaison pourraient convenir.According to the first embodiment described, the second portion 53 is adjustable in length. For this purpose, the second portion 53 comprises, for example, an attachment section 69, on the end of the attachment end 65, as well as a cover section 70, on the free end 66 side. to one another the sections 69, 70 in an adjustable manner. This means comprises for example a screw-nut 71, but of course other connecting structures could be suitable.

Les axes 58, 68 des deux articulations 57, 67 sont orientés sensiblement transversalement par rapport au dispositif 1, ce qui permet au lien 51 de couvrir uniformément la chaussure.The axes 58, 68 of the two joints 57, 67 are oriented substantially transversely relative to the device 1, which allows the link 51 to cover the shoe uniformly.

Le premier moyen de liaison 54 est prévu pour relier de façon amovible la deuxième portion 53 à la première portion 52, l'extrémité libre 56 de la première portion 52 étant au-dessus de la deuxième portion 53. Ce moyen 54 comprend par exemple un mécanisme de serrage à cliquet 80 solidarisé à la deuxième portion 53, au niveau de l'extrémité libre 66 de cette dernière. Le moyen de liaison 54 comprend également une série de dents 81 conformées sur la première portion 52. Les dents 81 se répartissent depuis l'extrémité libre 56 jusqu'à proximité de l'articulation 57. Les dents 81 coopèrent avec le cliquet pour bloquer le lien 51 à une longueur de serrage déterminée.The first connecting means 54 is provided for removably connecting the second portion 53 to the first portion 52, the free end 56 of the first portion 52 being above the second portion 53. This means 54 comprises for example a mechanism of ratchet clamping 80 secured to the second portion 53, at the free end 66 thereof. The connecting means 54 also comprises a series of teeth 81 shaped on the first portion 52. The teeth 81 are distributed from the free end 56 to the vicinity of the hinge 57. The teeth 81 cooperate with the ratchet to block the link 51 to a determined clamping length.

La première portion 52 est réalisée par exemple sous la forme d'une crémaillère, faite à partir d'une matière plastique. Les dents 81 et l'âme 82 de la première portion 52 forment de préférence une pièce monobloc.The first portion 52 is made for example in the form of a rack, made from a plastic material. The teeth 81 and the core 82 of the first portion 52 preferably form a single piece.

Le mécanisme de serrage 80 est vu de côté par exemple sur la figure 2. Il comprend une embase 83 en forme de U prévue pour guider la première portion 52. L'embase 83 comprend un premier flasque 84 et un deuxième flasque 85 reliés par un pont 86.The clamping mechanism 80 is seen from the side for example on the figure 2 . It comprises a U-shaped base 83 designed to guide the first portion 52. The base 83 comprises a first flange 84 and a second flange 85 connected by a bridge 86.

L'embase 83 est solidarisée à la deuxième portion 53 par exemple à l'aide d'un rivet d'axe 87.The base 83 is secured to the second portion 53 for example by means of a rivet axis 87.

Le mécanisme de serrage 80 comprend un cliquet 90 articulé selon un axe 91 entre les flasques 84, 85. Un moyen élastique non représenté, tel qu'un ressort, sollicite en permanence le cliquet 90 de façon qu'une zone de retenue 92 du cliquet soit poussée vers le pont 86. La zone de retenue 92 est représentée sous la forme d'une dent.The clamping mechanism 80 comprises a pawl 90 articulated along an axis 91 between the flanges 84, 85. An elastic means, not shown, such as a spring, constantly urges the pawl 90 so that a retaining zone 92 of the ratchet it is pushed towards the bridge 86. The retention zone 92 is represented in the form of a tooth.

Un levier d'entraînement 93 comprend d'une part une extrémité de manutention 94, et d'autre part une extrémité d'entraînement 95 munie d'au moins une dent 96.A drive lever 93 comprises on the one hand a handling end 94, and on the other hand a drive end 95 provided with at least one tooth 96.

Un bouton de libération 100 présente une surface de came 101 prévue pour appuyer sur une surface de came 102 du cliquet 90, et une extrémité de manutention 103 prévue pour être actionnée à la main.A release button 100 has a cam surface 101 provided to press a cam surface 102 of the pawl 90, and a handling end 103 provided to be operated by hand.

Le levier d'entraînement 93 et le bouton de libération 100 sont articulés sur un même axe 104, entre les flasques 84, 85. Un moyen élastique non représenté, tel qu'un ressort, sollicite en permanence le levier 93 de façon que l'extrémité de manutention 94 soit poussée vers le pont 86.The drive lever 93 and the release button 100 are articulated on the same axis 104, between the flanges 84, 85. An elastic means, not shown, such as a spring, constantly urges the lever 93 so that the handling end 94 is pushed to the bridge 86.

Ainsi en l'absence de toute sollicitation extérieure, les pièces constitutives du mécanisme de serrage 80 occupent chacun la portion montrée à la figure 2.Thus, in the absence of any external stress, the component parts of the clamping mechanism 80 each occupy the portion shown in FIG. figure 2 .

Lorsque la première portion 52 est présente le long du pont 86 entre les flasques 84, 85, c'est-à-dire dans l'embase 83, le cliquet 90 s'oppose à une augmentation de la longueur de serrage du lien 51. Cela signifie que l'extrémité 56 de la première portion 52 ne peut se déplacer, dans un sens qui va d'une arête interne 105 vers une arête externe 106 de l'embase 83.When the first portion 52 is present along the bridge 86 between the flanges 84, 85, that is to say in the base 83, the pawl 90 opposes an increase in the clamping length of the link 51. This means that the end 56 of the first portion 52 can not move in a direction that goes from an inner edge 105 to an outer edge 106 of the base 83.

Un déplacement dans le sens inverse est par contre possible. Pour ce faire un utilisateur peut actionner le levier d'entraînement 93, à l'aide de l'extrémité 94, de façon que les dents 96 entraînent la portion 52. Dans ce cas l'extrémité 56 de la portion 52 se déplace dans un sens qui va de l'arête externe 106 vers l'arête interne 105. Cela signifie que la longueur de serrage du lien 51 devient plus courte. Le serrage de la chaussure devient plus fort.On the other hand, a movement in the opposite direction is possible. To do this a user can actuate the drive lever 93, using the end 94, so that the teeth 96 drive the portion 52. In this case the end 56 of the portion 52 moves in a direction that goes from the outer edge 106 to the inner edge 105. This means that the clamping length of the link 51 becomes shorter. The tightening of the shoe becomes stronger.

A l'inverse l'utilisateur peut desserrer le lien, ou même libérer la chaussure en ouvrant le lien. Pour cela il lui suffit d'agir, par exemple avec un doigt, sur l'extrémité de manutention 103 du bouton de libération 100. Le levier d'entraînement 93 n'est alors pas sollicité, son extrémité de manutention 94 occupant la position la plus proche du pont 86.Conversely the user can loosen the link, or even release the shoe by opening the link. For this it is sufficient for it to act, for example with a finger, on the handling end 103 of the release button 100. The drive lever 93 is then not loaded, its handling end 94 occupying the position closer to bridge 86.

La surface de came 101 du bouton 100 appuie sur la surface de came 102 du cliquet 90, de façon que la zone de retenue 92 du cliquet 90 s'éloigne du pont 86 et de la première portion 52. Le lien 51 peut s'allonger, car le cliquet 90 ne retient plus la première portion 52.The cam surface 101 of the button 100 presses on the cam surface 102 of the pawl 90, so that the retaining zone 92 of the pawl 90 moves away from the bridge 86 and the first portion 52. The link 51 can lengthen because the pawl 90 no longer holds the first portion 52.

Bien entendu, dès que l'action sur le bouton 100 cesse, le cliquet 90 reprend une position de retenue.Of course, as soon as the action on the button 100 ceases, the pawl 90 resumes a holding position.

Un avantage, induit par la structure du mécanisme de serrage 80, est que l'action manuelle sur le bouton de libération 100 tend à allonger et à ouvrir le lien 51.One advantage, induced by the structure of the clamping mechanism 80, is that the manual action on the release button 100 tends to lengthen and open the link 51.

Comme on le comprend notamment à l'aide des figures 3 à 6, le tronçon de couverture 70 s'étend selon une direction longitudinale L depuis une première extrémité 110 jusqu'à une deuxième extrémité 111, transversalement d'un premier bord 112 à un deuxième bord 113, et en épaisseur d'une face d'appui 114 à une face libre 115. Bien entendu, la face d'appui 114 est destinée à appuyer sur un pied ou une chaussure. En complément on remarque que la direction longitudinale L est orientée transversalement par rapport au dispositif de retenue 1. On remarque aussi que la deuxième extrémité 111 du tronçon 70 se confond avec l'extrémité libre 66 de la deuxième portion 53 du lien 51.As is understood in particular by the help of Figures 3 to 6 , the cover section 70 extends in a longitudinal direction L from a first end 110 to a second end 111, transversely from a first edge 112 to a second edge 113, and in thickness of a bearing face 114 to a free face 115. Of course, the bearing face 114 is intended to press on a foot or a shoe. In addition, it will be noted that the longitudinal direction L is oriented transversely with respect to the retaining device 1. It should also be noted that the second end 111 of the section 70 merges with the free end 66 of the second portion 53 of the link 51.

Le tronçon de couverture 70 comprend une armature 120, laquelle est sensiblement inextensible longitudinalement pour offrir une stabilité de serrage du pied ou de la chaussure, et aussi flexible selon un axe transversal W pour permettre une adaptation au pied ou à la chaussure.The cover section 70 comprises a frame 120, which is substantially longitudinally inextensible to provide a clamping stability of the foot or boot, and also flexible along a transverse axis W to allow adaptation to the foot or the shoe.

L'armature 120 doit être comprise comme étant une ossature, ou un assemblage de pièces formant ossature.The frame 120 should be understood as a framework, or an assembly of structural parts.

Selon la première forme de réalisation décrite, comme le montre la figure 6, l'armature 120 comprend une première poutre 121 du côté du premier bord 112, et une deuxième poutre 122 du côté du deuxième bord 113, ainsi qu'un premier pont 123 au niveau de la première extrémité 110, et un deuxième pont 124 au niveau de la deuxième extrémité 111. En d'autres termes l'armature présente la forme d'une ellipse. Bien entendu, les ponts 123, 124 relient les poutres 121, 122 l'une à l'autre. En fait les ponts 123, 124 maintiennent les poutres éloignées l'une de l'autre.According to the first embodiment described, as shown by figure 6 , the armature 120 comprises a first beam 121 on the side of the first edge 112, and a second beam 122 on the side of the second edge 113, and a first bridge 123 at the first end 110, and a second bridge 124 at the level of the second end 111. In other words the frame has the shape of an ellipse. Of course, the bridges 123, 124 connect the beams 121, 122 to one another. In fact the bridges 123, 124 keep the beams apart from each other.

Selon la première forme de réalisation décrite, les poutres 121, 122 et les ponts 123, 124 forment une pièce monobloc. Cela revient à dire que l'armature 120 est une pièce monobloc. Mais il pourrait alternativement être prévu un assemblage.According to the first embodiment described, the beams 121, 122 and the bridges 123, 124 form a single piece. This amounts to saying that the armature 120 is a single piece. But it could alternatively be provided an assembly.

Les poutres 121, 122 et les ponts 123, 124 forment un pourtour continu autour d'une ouverture centrale traversante 125.The beams 121, 122 and the bridges 123, 124 form a continuous periphery around a central through opening 125.

L'armature 120 comprend par exemple une matière plastique, obtenue par toute technique comme le moulage par injection ou autre. Cette matière peut être un polyéthylène, un polyuréthane, ou tout équivalent. Les poutres 121, 122 sont dimensionnées pour être flexibles selon l'axe transversal W, et sensiblement inextensibles selon la direction longitudinale L. C'est pourquoi la section d'une poutre 121, 122 est très supérieure à la section d'un fil utilisé pour faire un tissu ou une sangle. La section d'une poutre est égale ou supérieure à 1 mm2. Il est fréquent que la section d'une poutre soit supérieure à 5 mm2.The armature 120 comprises for example a plastic material, obtained by any technique such as injection molding or the like. This material may be a polyethylene, a polyurethane, or any equivalent. The beams 121, 122 are dimensioned to be flexible along the transverse axis W, and substantially inextensible in the longitudinal direction L. This is why the section of a beam 121, 122 is much greater than the section of a wire used to make a cloth or a strap. The section of a beam is equal to or greater than 1 mm 2 . It is common for the section of a beam to be greater than 5 mm 2 .

En complément il est prévu un trou 130 dans le premier pont 123, pour contribuer à réaliser la liaison 71 entre les tronçons d'attache 69 et de couverture 70. Il est aussi prévu quelques trous dans le deuxième pont 124, par exemple trois 131, 132, 133, pour permettre la mise en place du mécanisme 80 sur le tronçon de couverture 70.In addition, there is provided a hole 130 in the first bridge 123, to contribute to making the connection 71 between the attachment sections 69 and cover 70. There are also provided a few holes in the second bridge 124, for example three 131, 132, 133, to allow the establishment of the mechanism 80 on the cover section 70.

Par ailleurs un élément de confort 140 entoure en partie au moins l'armature 120.Furthermore, a comfort element 140 partially surrounds at least the armature 120.

Selon l'invention, comme on le comprend notamment à l'aide des figures 3 à 5, l'élément de confort 140 comprend une matière synthétique moulée sur l'armature.According to the invention, as is understood in particular by means of Figures 3 to 5 , the comfort element 140 comprises a synthetic material molded on the frame.

Le moulage de l'élément 140 est une technique simple et de mise en oeuvre rapide, par rapport à une gaine traditionnelle pour laquelle il faut différentes couches cousues. De plus le moulage permet un contact intime entre l'élément 140 et l'armature 120. En conséquence les contraintes, liées par exemple aux efforts de conduite, sont réparties au sein de l'armature. En d'autres termes, les contraintes se répartissent notamment dans les poutres 121, 122.The molding of the element 140 is a simple technique and rapid implementation, compared to a traditional sheath for which it takes different layers sewn. In addition, the molding allows intimate contact between the element 140 and the armature 120. As a result, the stresses, related for example to the driving forces, are distributed within the armature. In other words, the stresses are distributed in particular in the beams 121, 122.

Selon la première forme de réalisation, l'élément de confort 140 recouvre l'armature 120 dans sa quasi-totalité. Cela signifie que l'élément 140 entoure la première poutre 121, la deuxième poutre 122, et aussi le premier pont 123 et le deuxième pont 124. En d'autres termes les poutres 121, 122 et les ponts 123, 124 sont noyés dans la matière synthétique comprise dans l'élément 140.According to the first embodiment, the comfort element 140 covers the armature 120 in almost all. This means that the element 140 surrounds the first beam 121, the second beam 122, and also the first bridge 123 and the second bridge 124. In other words the beams 121, 122 and the bridges 123, 124 are embedded in the synthetic material included in item 140.

En complément cette matière constitutive de l'élément s'étend aussi dans l'ouverture 125 pour, toujours selon la première forme de réalisation, la remplir totalement. En fait l'élément de confort 140 forme un volet de fermeture 141 de l'ouverture 125. Le volet 141 s'étend entre les poutres 121, 122 et entre les ponts 123, 124.In addition, this constitutive material of the element also extends into the opening 125 so that, according to the first embodiment, it is completely filled. In fact the comfort element 140 forms a closure flap 141 of the opening 125. The flap 141 extends between the beams 121, 122 and between the bridges 123, 124.

Pour réaliser le tronçon de couverture 70, une étape consiste à fabriquer l'armature 120 par toute technique connue, comme l'injection d'une matière plastique. Une étape ultérieure consiste à placer l'armature 120 dans un moule plus grand, c'est-à-dire laissant la place pour l'élément 140. Celui-ci est surmoulé sur l'armature 120, par toute technique connue telle que l'injection.To achieve the cover section 70, a step is to manufacture the armature 120 by any known technique, such as the injection of a plastic material. A subsequent step is to place the armature 120 in a larger mold, that is to say leaving room for the element 140. The latter is overmolded on the armature 120, by any known technique such as the 'injection.

L'armature 120 et l'élément 140 sont réalisés chacuns à partir de toute matière synthétique telle qu'un polyuréthane, un polyamide, un polyéthylène, ou tout équivalent. Cependant l'élément 140 est déformable élastiquement de manière réversible, à la manière d'un ressort. Cela revient à dire qu'il 140 est extensible, se déformant lors d'une sollicitation pour ensuite reprendre sa forme initiale quand la sollicitation cesse. Par contraste l'armature 120 est sensiblement indéformable élastiquement. Cela revient à dire qu'elle 120 est inextensible. En conséquence les poutres 121, 122 ne s'allongent pas lors du serrage du lien.The armature 120 and the element 140 are each made from any synthetic material such as polyurethane, polyamide, polyethylene, or any equivalent. However, the element 140 is elastically deformable reversibly, in the manner of a spring. That is to say that it is extensible, deforming during a solicitation and then resume its original form when the solicitation ceases. In contrast, the armature 120 is substantially elastically deformable. It amounts to saying that it is inextensible. As a result, the beams 121, 122 do not lengthen when tightening the link.

Mais la souplesse de l'élément 140, et donc du volet 141, permet au tronçon de couverture 70 de se plaquer uniformément sur le pied ou la chaussure. Cela est particulièrement vrai là où les courbures varient, par exemple vers le cou-de-pied ou vers l'avant du pied. Le volet 141 peut se déformer pour épouser une partie de la chaussure qui tendrait à passer entre les poutres 121, 122.But the flexibility of the element 140, and therefore the shutter 141, allows the cover section 70 to flatten uniformly on the foot or the shoe. This is especially true where the curvatures vary, for example towards the instep or towards the front of the foot. The flap 141 may deform to marry a portion of the shoe that would tend to pass between the beams 121, 122.

On observe donc une grande adaptabilité géométrique du tronçon 70 à un pied ou à une chaussure.There is therefore a great geometric adaptability of the section 70 to a foot or a shoe.

La molécule de base qui sert à faire l'armature 120 ou l'élément 140 peut être la même, par exemple du polyuréthane. Mais cette molécule est agencée spécifiquement selon les besoins mécaniques requis.The base molecule used to make the armature 120 or the element 140 may be the same, for example polyurethane. But this molecule is arranged specifically according to the mechanical needs required.

La deuxième forme de réalisation est décrite ci-après à l'aide de la figure 7. Pour des raisons de commodité, les éléments communs avec la première forme sont désignés par les mêmes références.The second embodiment is described below using the figure 7 . For the sake of convenience, the elements common with the first form are designated by the same references.

Ainsi dans la deuxième forme on retrouve un tronçon de couverture 70, une armature 120 avec une première poutre 121, une deuxième poutre 122, un premier pont 123 et un deuxième pont 124, et une ouverture 125.Thus in the second form there is a cover section 70, an armature 120 with a first beam 121, a second beam 122, a first bridge 123 and a second bridge 124, and an opening 125.

Ce qui rend la deuxième forme de réalisation différente de la première, c'est que la matière constitutive de l'élément de confort 150 ne remplit pas totalement l'ouverture 125. Ici la matière forme un tamis 151 dans l'ouverture 125, à la manière d'une structure maillée. Bien entendu le tamis 151 s'étend entre les poutres 121, 122 et entre les ponts 123, 124. Les effets techniques et les avantages qui en découlent sont similaires à ceux de la première forme de réalisation.What makes the second embodiment different from the first is that the constituent material of the comfort element 150 does not completely fill the opening 125. Here the material forms a sieve 151 in the opening 125, to the way of a mesh structure. Of course, the screen 151 extends between the beams 121, 122 and between the bridges 123, 124. The technical effects and the benefits derived therefrom are similar to those of the first embodiment.

D'une manière générale, l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In general, the invention is made from materials and according to implementation 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.
