Abstract

The device (1) has lateral and medial flanges (12, 13) delimiting a zone (14) for receiving a foot or a shoe, and two straps (20, 21). Each strap is connected to the flanges (12, 13) by a lateral fastener (30) and a medial fastener, respectively. The strap (21) has a primary fastening portion (22), a covering portion (23), and a secondary fastening portion. An elongated leg adjusts curvature of the three portions.

Description

L'invention se rapporte à un dispositif de maintien d'un pied ou d'une chaussure, pour lequel le maintien du pied ou de la chaussure se fait à l'aide d'au moins un lien. L'invention se rapporte aussi un lien destiné à faire partie du dispositif.The invention relates to a device for maintaining a foot or a shoe, for which the maintenance of the foot or the shoe is done using at least one link. The invention also relates to a link intended to be part of the device.

De tels dispositifs sont utilisés pour la pratique du surf sur neige ou snowboard, du ski sur neige ou sur eau, de la raquette à neige, du patin à roues, ou autre.Such devices are used for snowboarding or snowboarding, skiing on snow or water, snowshoeing, rollerblading, or other.

Un dispositif à liens selon l'art antérieur comprend généralement une partie latérale et une partie médiale qui délimitent entre eux une zone d'accueil du pied ou de la chaussure, ainsi qu'au moins un lien relié à chacune des parties latérale et médiale par une attache latérale et par une attache médiale. Chaque lien sert à maintenir le pied ou la chaussure dans la zone d'accueil.A link device according to the prior art generally comprises a lateral part and a medial part which delimit between them a reception area of the foot or the shoe, as well as at least one link connected to each of the lateral and medial parts by a lateral attachment and a medial attachment. Each link is used to hold the foot or the shoe in the reception area.

Chaque portion d'un lien présente une courbure variable, pour s'adapter au pied ou à la chaussure. C'est pourquoi chaque portion d'un lien comprend une ou plusieurs couches de matériaux plus ou moins souples tels que du plastique, du caoutchouc, du tissu, du cuir, ou tout matériau équivalent. Les couches sont conformées pour que le lien présente naturellement une forme incurvée, proche de celle qui est sienne quand il serre le pied ou la chaussure.Each portion of a link has a variable curvature, to adapt to the foot or the shoe. This is why each portion of a link comprises one or more layers of more or less flexible materials such as plastic, rubber, fabric, leather, or any equivalent material. The layers are shaped so that the link naturally has a curved shape, close to that which is hers when it closes the foot or the shoe.

Les attaches quant à elles orientent les extrémités du lien selon des directions sensiblement tangentes au pied ou à la chaussure.The fasteners themselves orient the ends of the link in directions substantially tangent to the foot or the shoe.

Ainsi même en cas d'ouverture du lien, pour permettre le passage du pied ou de la chaussure dans un sens de rapprochement ou d'éloignement de la zone d'accueil, chaque portion du lien tend à rester dans une position de contour du pied ou de la chaussure. Par suite le serrage du lien se fait avec pas ou peu de déformation. Cela favorise une homogénéité de serrage, les pressions de contact exercées par le lien étant réparties avec uniformité.Thus, even if the link is opened, to allow the foot or the shoe to move in a direction of approaching or moving away from the reception area, each portion of the link tends to remain in a position of contour of the foot. or shoe. As a result the tightening of the link is done with little or no deformation. This promotes uniformity of clamping, the contact pressures exerted by the link being distributed uniformly.

Cependant l'utilisation du dispositif selon l'art antérieur présente un inconvénient. Lorsqu'il veut chausser ou déchausser, l'utilisateur doit maintenir au moins une portion d'un lien à l'écart de la trajectoire du pied ou de la chaussure. Cela est particulièrement vrai pour le chaussage, qui implique le rapprochement vers la zone d'accueil. En effet si elle n'est pas écartée, la portion du lien se retrouve sous le pied ou sous la chaussure. Dans ce cas la fermeture du lien n'est plus possible, et le maintien du pied ou de la chaussure ne se fait pas. Dans un sens d'éloignement, lors du déchaussage, la présence de la portion est également gênante. Si elle n'est pas maintenue à l'écart, elle frotte sur le pied ou la chaussure.However, the use of the device according to the prior art has a disadvantage. When he wants to put on or off, the user must maintain at least a portion of a link away from the path of the foot or the shoe. This is especially true for footwear, which involves getting closer to the docking area. Indeed if it is not removed, the portion of the link is found under the foot or under the shoe. In this case the closure of the link is no longer possible, and the maintenance of the foot or the shoe is not done. In a sense of distance, during the heaving, the presence of the portion is also troublesome. If she is not kept out of the way, she rubs on the foot or the shoe.

Souvent la présence d'une portion de lien sur la trajectoire du pied ou de la chaussure est une gêne pour l'utilisateur.Often the presence of a portion of the link on the path of the foot or the shoe is an inconvenience for the user.

Le document DE-A-10149813 décrit un lien comprenant une portion dont la courbure est variable mais non ajustable lorsqu'il est en position ouverte.Document DE-A-10149813 describes a link comprising a portion whose curvature is variable but not adjustable when it is in the open position.

L'un des buts de l'invention est de permettre une libération temporaire et stable, partielle ou totale, de la trajectoire du pied ou de la chaussure, cela pour un sens de rapprochement ou d'éloignement de la zone d'accueil.One of the aims of the invention is to allow a temporary and stable release, partial or total, of the trajectory of the foot or the shoe, for a sense of approximation or removal from the reception area.

Dans cette optique l'invention propose un dispositif de maintien d'un pied ou d'une chaussure, le dispositif comprenant une partie latérale et une partie médiale délimitant une zone d'accueil du pied ou de la chaussure, ainsi qu'au moins un lien relié à chacune des parties latérale et médiale par une attache latérale et par une attache médiale, le lien comprenant au moins une portion dont la courbure est variable.In this respect, the invention proposes a device for holding a foot or a shoe, the device comprising a lateral part and a medial part delimiting a foot or shoe receiving zone, and at least one link connected to each of the lateral and medial portions by a lateral attachment and a medial clip, the link comprising at least one portion having a variable curvature.

Le dispositif de maintien selon l'invention est caractérisé par le fait qu'il comprend un moyen d'ajustement de la courbure d'une partie au moins de la portion.The holding device according to the invention is characterized in that it comprises means for adjusting the curvature of at least part of the portion.

L'utilisateur peut donc ajuster la courbure de la portion pour la maintenir en partie au moins, voire en totalité, à l'écart de la trajectoire du pied ou de la chaussure.The user can adjust the curvature of the portion to maintain at least some, or all, away from the path of the foot or the shoe.

Ainsi rien ou presque ne s'oppose au chaussage ou au déchaussage. Un pied ou une chaussure peut passer plus librement dans un sens de rapprochement ou d'éloignement de la zone d'accueil.Thus nothing or almost nothing opposes the boot or heaving. A foot or shoe can move more freely in a direction of approximation or distance from the reception area.

Un avantage qui en découle est une plus grande facilité de chaussage ou de déchaussage, car l'utilisateur n'a pas à maintenir la portion écartée en même temps qu'il déplace son pied. Par conséquent il peut prendre des positions stables et confortables, et il peut se concentrer sur le mouvement du pied.A benefit that arises is greater ease of entry or heaving, because the user does not have to maintain the portion apart at the same time he moves his foot. Therefore he can take stable and comfortable positions, and he can focus on the movement of the foot.

Bien entendu la portion écartée peut être ramenée dans un sens de fermeture du lien.Of course the separated portion can be reduced in a direction of closure of the link.

Bien que les exemples décrits après se rapportent plutôt au domaine du snowboard, il doit être compris qu'ils s'appliquent aussi à d'autres domaines comme évoqué avant.Although the examples described below relate more to the field of snowboarding, it should be understood that they also apply to other areas as mentioned before.

Le premier exemple est présenté à l'aide des figures 1 à 7.The first example is presented using Figures 1 to 7.

Comme on le voit sur la figure 1, un dispositif de maintien 1 permet le maintien temporaire sur une planche 2 d'une chaussure non représentée.As seen in Figure 1, a holding device 1 allows the temporary maintenance on a board 2 of a shoe not shown.

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

L'embase 3 présente une face supérieure 6 prévue pour être en regard de la semelle de la chaussure, et une face inférieure 7 prévue pour être au-dessus de la planche.The base 3 has an upper face 6 provided to be facing the sole of the shoe, and a lower face 7 provided to be above the board.

L'embase 3 est retenue à la planche 2 par un moyen représenté sous la forme d'un disque 10, lui-même retenu à la planche 2 par des vis 11.The base 3 is retained in the board 2 by a means represented in the form of a disc 10, itself retained in the board 2 by screws 11.

Bien entendu, d'autres moyens de retenue de l'embase 3 pourraient être prévus.Of course, other means for retaining the base 3 could be provided.

L'embase 3 est bordée latéralement par un flasque latéral 12 et par un flasque médial 13. Chacun des flasques 12, 13 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 respectively form a lateral or medial part of the device 1 to define a reception area 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.

Les flasques 12, 13 sont reliés par un arceau 15 au niveau de l'extrémité arrière 4. De préférence, l'embase 3, les flasques 12, 13 et l'arceau 15 forment une pièce monobloc réalisée par exemple en matière synthétique. Cependant il pourrait être prévu que les flasques ou l'arceau soient des pièces solidarisées à l'embase par tout autre moyen, tel qu'un collage, une soudure, un vissage, un emboîtement, ou autre.The flanges 12, 13 are connected by a hoop 15 at the rear end 4. Preferably, the base 3, the flanges 12, 13 and the hoop 15 form a single piece made for example of synthetic material. However it could be provided that the flanges or the hoop are parts secured to the base by any other means, such as gluing, welding, screwing, interlocking, or other.

De façon accessoire, un élément d'appui arrière 16 permet à un utilisateur de prendre des appuis arrière avec le bas de jambe. L'élément d'appui arrière 16 est solidarisé aux flasques 12, 13 par exemple au moyen d'une articulation 17.In an accessory manner, a rear support member 16 allows a user to take backrests with the lower leg. The rear support element 16 is secured to the flanges 12, 13 for example by means of a hinge 17.

Il est également prévu deux liens pour maintenir de façon amovible la chaussure sur l'embase 3, entre les flasques 12, 13, dans la zone d'accueil 14.There are also two links for detachably holding the boot on the base 3, between the flanges 12, 13, in the reception zone 14.

Un premier lien 20 se situe vers l'avant, au niveau de l'articulation métatarsophalangienne quand le pied est maintenu. Un deuxième lien 21 se situe vers l'arrière, au niveau du cou-de-pied quand le pied est maintenu.A first link 20 lies forward, at the metatarsophalangeal joint when the foot is maintained. A second link 21 is located aft, at the instep when the foot is held.

Chacun des liens 20, 21 s'étend transversalement entre les flasques 12, 13.Each of the links 20, 21 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.

Selon le premier exemple de réalisation de l'invention, comme on le voit mieux sur la figure 2, le deuxième lien 21 est représenté sous la forme d'une association de trois portions, qui sont une première portion d'attache 22, une portion de couverture 23 de la chaussure, et une deuxième portion d'attache 24.According to the first embodiment of the invention, as best seen in FIG. 2, the second link 21 is represented in the form of a combination of three portions, which are a first attachment portion 22, a portion 23 of the boot, and a second fastening portion 24.

La première portion 22 présente une extrémité d'attache 25 et une extrémité libre 26. L'extrémité d'attache 25 est reliée au flasque latéral 12 par une attache latérale. Cette dernière est représentée sous la forme d'une articulation, réalisée par exemple à l'aide d'un rivet 30.The first portion 22 has an attachment end 25 and a free end 26. The attachment end 25 is connected to the lateral flange 12 by a lateral attachment. The latter is represented in the form of a hinge, made for example by means of a rivet 30.

Un premier moyen de liaison est prévu pour relier de façon amovible la portion de couverture 23 à la première portion 22, l'extrémité libre 26 de la première portion d'attache 22 étant au-dessus de la portion de couverture 23. Ce moyen comprend par exemple un mécanisme de serrage à cliquet 31 fixé à la portion de couverture 23, au niveau d'une première extrémité 32 de cette dernière. Le moyen de liaison de la portion de couverture 23 à la première portion 22 comprend également une série de dents 33 conformées sur la première portion 22. Les dents 33 se répartissent depuis l'extrémité libre 26 jusqu'à proximité de l'articulation 30.A first connecting means is provided for removably connecting the cover portion 23 to the first portion 22, the free end 26 of the first attachment portion 22 being above the cover portion 23. This means comprises for example a ratchet clamping mechanism 31 attached to the cover portion 23, at a first end 32 thereof. The means for connecting the covering portion 23 to the first portion 22 also comprises a series of teeth 33 shaped on the first portion 22. The teeth 33 are distributed from the free end 26 to near the joint 30.

En agissant sur un levier 34 du mécanisme 31 il est possible de serrer le lien 21 en approchant la première extrémité 32 vers le flasque latéral 12. En agissant sur un bouton 35 du mécanisme 31, il est possible de desserrer le lien 21, ou même de l'ouvrir. Dans ce dernier cas, la portion de couverture 23 et la première portion 22 sont séparées.By acting on a lever 34 of the mechanism 31 it is possible to tighten the link 21 by approaching the first end 32 to the side flange 12. By acting on a button 35 of the mechanism 31, it is possible to loosen the link 21, or even to open it. In the latter case, the covering portion 23 and the first portion 22 are separated.

Bien entendu, d'autres moyens pourraient être prévus pour relier la portion de couverture 23 à la première portion 22.Of course, other means could be provided for connecting the covering portion 23 to the first portion 22.

La deuxième portion d'attache 24 présente quant à elle une extrémité d'attache 40 et une extrémité libre 41. L'extrémité d'attache 40 est reliée au flasque médial 13 par une attache médiale. Cette dernière est représentée sous la forme d'une articulation, réalisée par exemple à l'aide d'un rivet 42.The second attachment portion 24 has for its part an attachment end 40 and a free end 41. The attachment end 40 is connected to the medial flange 13 by a medial clip. The latter is represented in the form of a hinge, made for example by means of a rivet 42.

Un deuxième moyen de liaison est prévu pour relier de façon réglable la portion de couverture 23 à la deuxième portion 24, l'extrémité libre 41 de la deuxième portion d'attache 24 étant au-dessus de la portion de couverture 23. Ce moyen comprend par exemple une vis 43 qui se visse dans la portion de couverture 23, au niveau d'une deuxième extrémité 44 de cette dernière. La vis 43 traverse l'un des trous 45 percés dans la deuxième portion 24.A second connecting means is provided for adjustably connecting the covering portion 23 to the second portion 24, the free end 41 of the second fastening portion 24 being above the covering portion 23. This means comprises for example a screw 43 which is screwed into the cover portion 23, at a second end 44 thereof. The screw 43 passes through one of the holes 45 drilled in the second portion 24.

Ainsi, l'utilisateur peut faire en sorte que la deuxième extrémité 44 de la portion de couverture 23 soit à proximité du flasque médial 13. Le réglage de position, de la portion de couverture 23 par rapport à la deuxième portion 24, est rarement modifié. Il est prévu pour tenir compte de l'encombrement de la chaussure.Thus, the user can make the second end 44 of the covering portion 23 near the medial flange 13. The position adjustment of the covering portion 23 with respect to the second portion 24 is rarely modified . It is intended to take account of the footprint of the shoe.

Les deux articulations se font sensiblement selon un axe transversal du dispositif, ce qui permet au deuxième lien 21 de couvrir uniformément la chaussure.The two joints are substantially along a transverse axis of the device, which allows the second link 21 to uniformly cover the shoe.

Bien entendu, les articulations pourraient être réalisées par d'autres moyens tels que des vis, des tourillons, ou autre.Of course, the joints could be made by other means such as screws, pins, or other.

De même les attaches du lien 21 aux flasques 12, 13 pourraient être faites par d'autres moyens, tel qu'un enroulement autour d'un passant, ou autre.Similarly, the fasteners of the link 21 to the flanges 12, 13 could be made by other means, such as a winding around a passer, or other.

Le lien 21 est sensiblement inextensible dans le sens de sa longueur, c'est-à-dire d'un flasque à l'autre. Les matériaux qui le constituent sont choisis à cet effet. Notamment les première et deuxième portions 22, 24 comprennent de préférence respectivement une bande 46, 47 allongée faite à partir d'une matière synthétique, telle qu'un polyamide ou un polyuréthane armé ou non. Chaque bande 46, 47 s'étend en longueur respectivement depuis l'extrémité d'attache 25, 40 jusqu'à l'extrémité libre 26, 41 de la portion d'attache 22, 24.The link 21 is substantially inextensible in the direction of its length, that is to say from one flange to the other. The materials that constitute it are chosen for this purpose. In particular, the first and second portions 22, 24 preferably comprise, respectively, an elongated strip 46, 47 made from a synthetic material, such as a polyamide or a polyurethane, which may or may not be reinforced. Each strip 46, 47 extends in length respectively from the attachment end 25, 40 to the free end 26, 41 of the attachment portion 22, 24.

La portion de couverture 23 quant à elle présente aussi une forme allongée. Elle s'étend en longueur entre les première 32 et deuxième 44 extrémités.The covering portion 23 in turn has an elongated shape. It extends in length between the first 32 and second 44 ends.

Chaque portion 22, 23, 24 est néanmoins plus ou moins souple. Sa courbure est variable, et elle peut plier pour s'adapter au pied ou à la chaussure.Each portion 22, 23, 24 is nevertheless more or less flexible. Its curvature is variable, and it can bend to fit the foot or the shoe.

Selon l'invention, le dispositif de maintien 1 comprend un moyen d'ajustement de la courbure d'une partie au moins d'une portion 22, 23, 24 du lien 21.According to the invention, the holding device 1 comprises means for adjusting the curvature of at least a portion of a portion 22, 23, 24 of the link 21.

Il est ainsi possible de donner à la portion 22, 23, 24 par exemple une forme de contournement de la chaussure, ou bien une forme de dégagement à l'écart de la zone d'accueil 14. Dans ce second cas les chaussages et déchaussages sont facilités.It is thus possible to give the portion 22, 23, 24 for example a form of bypass of the shoe, or a form of clearance away from the reception area 14. In this second case the shoes and heaps are facilitated.

Selon le premier exemple de réalisation de l'invention, comme on le comprend à l'aide des figures 3 à 7, un moyen d'ajustement permet d'ajuster la courbure d'une partie de la première portion 22 du deuxième lien 21. Ce moyen comprend un élément déformable, représenté par une patte allongée 50. Cette dernière est associée à la bande 46 pour constituer la première portion d'attache 22. Plus précisément la patte 50 est noyée dans la bande 46. Cependant la patte 50 aurait pu être associée à la bande 46 autrement, par exemple en étant collée à la surface de la bande, ou par tout autre moyen. La patte 50 est orientée sensiblement dans le sens de la longueur de la bande 46. De cette façon le long de la patte 50, cette dernière et la bande 46 présentent une même courbure.According to the first embodiment of the invention, as can be understood from FIGS. 3 to 7, an adjustment means makes it possible to adjust the curvature of a portion of the first portion 22 of the second link 21. This means comprises a deformable element, represented by an elongate tab 50. The latter is associated with the band 46 to form the first attachment portion 22. More precisely the tab 50 is embedded in the band 46. However the tab 50 could have been be associated with the band 46 otherwise, for example by being glued to the surface of the band, or by any other means. The tab 50 is oriented substantially in the direction of the length of the strip 46. In this way along the tab 50, the latter and the band 46 have the same curvature.

La patte 50 contient de préférence un métal ou un alliage métallique. Par exemple il peut s'agir d'un alliage de cuivre, d'acier, ou d'un autre matériau. Dans le cas de l'acier, il peut être recherché une limite élastique réduite. Cela rend le moyen d'ajustement déformable plastiquement. Ainsi par ses manipulations l'utilisateur peut plier la patte 50, et une partie de la première portion d'attache 22 par voie de conséquence. La patte 50 impose sa propre courbure à la bande 46.The tab 50 preferably contains a metal or a metal alloy. For example, it may be an alloy of copper, steel, or other material. In the case of steel, a reduced yield strength can be sought. This makes the adjustment means plastically deformable. Thus by its manipulations the user can fold the tab 50, and a portion of the first attachment portion 22 accordingly. The tab 50 imposes its own curvature on the band 46.

Lorsque la patte 50 a été pliée, elle conserve naturellement la courbure qui lui a été donnée. Cela est dû au fait que la patte 50 est un élément qui se déforme plastiquement. Elle ne prendra une autre forme que si on la plie autrement. Il est bien entendu possible de plier la patte 50 pour écarter la première portion 22 en dehors de la zone d'accueil 14, comme c'est le cas à la figure 7. L'utilisateur peut ainsi passer le pied ou la chaussure sans gêne. Un pliage dans le sens inverse ramène l'extrémité libre 26 de la première portion d'attache 22 vers le flasque médial 13. Cela permet à la portion 22 de couvrir l'embase 3, et le pied ou la chaussure par voie de conséquence. Cela permet aussi une fermeture du deuxième lien 21, comme c'est le cas sur les figures 1 et 2.When the tab 50 has been folded, it naturally retains the curvature that has been given to it. This is due to the fact that the tab 50 is an element that deforms plastically. It will take another form only if it is folded otherwise. It is of course possible to fold the tab 50 to separate the first portion 22 outside the reception area 14, as is the case in Figure 7. The user can thus pass the foot or the shoe without embarrassment . A folding in the opposite direction brings the free end 26 of the first attachment portion 22 towards the medial flange 13. This allows the portion 22 to cover the base 3, and the foot or the shoe by consequence. This also allows a closure of the second link 21, as is the case in Figures 1 and 2.

En se tournant plus spécialement vers les figures 3 à 6, on remarque que la patte 50 présente un corps allongé 51 délimité par une première 52 et une deuxième 53 extrémité, ainsi que par un premier 54 et un deuxième 55 bords. De manière non limitative, les extrémités 52, 53 sont arrondies et les bords 54, 55 sont sensiblement droits. Cela confère à la patte 50 une forme oblongue. Il s'ensuit une réduction du risque d'apparition de fissures dans la bande 46 de la première portion 22.Turning more particularly to Figures 3 to 6, it is noted that the tab 50 has an elongate body 51 defined by a first 52 and a second 53 end, and a first 54 and a second 55 edges. Without limitation, the ends 52, 53 are rounded and the edges 54, 55 are substantially straight. This gives the tab 50 an oblong shape. It follows a reduction of the risk of occurrence of cracks in the band 46 of the first portion 22.

La patte 50 est aussi percée par un trou 56 pour le passage du rivet 30. Ainsi ce sont à la fois la patte 50 et la bande 46 qui supportent les efforts exercés dans la portion d'attache 22.The tab 50 is also pierced by a hole 56 for the passage of the rivet 30. Thus it is both the tab 50 and the band 46 that support the forces exerted in the attachment portion 22.

La patte 50 est encore ajourée vers la deuxième extrémité 53, au-delà du trou 56. Par exemple une fente 57 aux extrémités arrondies 58, 59 traverse la patte 50. La fente 57 affaiblit localement la patte 50 sur un plan mécanique. Il est ainsi plus facile de plier la patte 50 au niveau de la fente 57. De plus la fente 57 favorise l'implantation de la patte 50 dans la matière constitutive de la bande 46.The tab 50 is still perforated towards the second end 53, beyond the hole 56. For example a slot 57 with rounded ends 58, 59 passes through the tab 50. The slot 57 locally weakens the tab 50 on a mechanical plane. It is thus easier to fold the tab 50 at the slot 57. In addition the slot 57 promotes the implantation of the tab 50 in the material constituting the band 46.

De préférence la patte 50 est sensiblement centrée latéralement entre un premier 65 et un deuxième 66 bords de la bande 46. La patte 50 est aussi sensiblement centrée dans le sens de l'épaisseur, entre une première face 67 qui présente les dents 33 et une deuxième face 68 plus lisse. Cette disposition favorise une répartition équilibrée des efforts exercés dans la première portion d'attache 22.Preferably the tab 50 is substantially centered laterally between a first 65 and a second 66 edges of the strip 46. The tab 50 is also substantially centered in the direction of the thickness, between a first face 67 which has the teeth 33 and a second face 68 smoother. This arrangement promotes a balanced distribution of the forces exerted in the first attachment portion 22.

Bien entendu d'autres formes et d'autres lieux d'implantation peuvent être prévus pour la patte 50.Of course other forms and other locations may be provided for the tab 50.

Le deuxième exemple de réalisation de l'invention est présenté à l'aide des figures 8 à 16. Pour des raisons de commodité, seules les différences par rapport au premier exemple sont décrites.The second embodiment of the invention is presented with reference to FIGS. 8 to 16. For reasons of convenience, only the differences with respect to the first example are described.

La figure 8 est une vue à plat d'une deuxième portion d'attache 80 pour un lien, non représenté, qui est similaire au deuxième lien 21 du premier exemple.Figure 8 is a plan view of a second attachment portion 80 for a link, not shown, which is similar to the second link 21 of the first example.

La deuxième portion d'attache 80 s'étend en longueur entre une extrémité d'attache 81 et une extrémité libre 82, en largeur entre un premier bord 83 et un deuxième bord 84, et en épaisseur entre une première face 85 et une deuxième face 86.The second attachment portion 80 extends in length between a fastening end 81 and a free end 82, in width between a first edge 83 and a second edge 84, and in thickness between a first face 85 and a second face 86.

Des trous 87 ménagés dans la portion d'attache 80, du côté de l'extrémité libre 82, permettent le passage d'un moyen de solidarisation à une portion de couverture. Ce moyen peut être une vis, ou autre.Holes 87 formed in the attachment portion 80, the side of the free end 82, allow the passage of a securing means to a covering portion. This means can be a screw, or other.

Un trou 88, ménagé quant à lui du côté de l'extrémité d'attache 81, permet le passage d'un moyen d'attache tel qu'un rivet.A hole 88, formed on the side of the attachment end 81, allows the passage of a fastening means such as a rivet.

Selon le deuxième exemple de réalisation de l'invention, un moyen d'ajustement permet d'ajuster la courbure d'une partie de la deuxième portion 80 du deuxième lien. Ce moyen comprend un élément déformable, représenté sous la forme d'un maillon 95, associé à une bande 96 pour constituer la deuxième portion 80.According to the second embodiment of the invention, an adjustment means makes it possible to adjust the curvature of a portion of the second portion 80 of the second link. This means comprises a deformable element, represented in the form of a link 95, associated with a band 96 to form the second portion 80.

Le maillon 95 est apposé à la bande 96, du côté de la première face 85.The link 95 is affixed to the band 96, on the side of the first face 85.

Le maillon 95 présente une première 97 et une deuxième 98 extrémités qui sont par exemple encastrées respectivement dans un premier 99 et un deuxième 100 plots en saillie sur la première face 85.The link 95 has a first 97 and a second 98 ends which are for example embedded respectively in a first 99 and a second 100 pads projecting on the first face 85.

Bien entendu, tout moyen autre qu'un encastrement pourrait convenir, comme un vissage, un rivetage, un collage, ou autre. Il aurait aussi pu être prévu que le maillon 95 soit ailleurs, par exemple du côté de la deuxième face 86, dans une cavité de la bande 96, ou autre.Of course, any means other than a recess could be suitable, such as screwing, riveting, gluing, or other. It could also be expected that the link 95 is elsewhere, for example on the side of the second face 86, in a cavity of the strip 96, or other.

Le maillon 95 présente une première 101 et une deuxième 102 lamelles qui s'étendent respectivement entre ses extrémités 97, 98. De préférence les lamelles 101, 102 sont orientées sensiblement selon la longueur de la bande 96.The link 95 has a first 101 and a second 102 lamellae which extend respectively between its ends 97, 98. Preferably the lamellae 101, 102 are oriented substantially along the length of the band 96.

Comme on le voit mieux sur la figure 9, le maillon 95 est fabriqué à partir d'une ébauche 103 en forme d'arceau. Un pont 104 relie les lamelles 101, 102 vers la première extrémité 97 du maillon 95, alors que vers la deuxième extrémité 98 du maillon les lamelles 101, 102 présentent respectivement des première 105 et deuxième 106 extrémités libres. De préférence les lamelles 101, 102 et le pont 104 forment une pièce monobloc. Cependant il aurait pu être prévu plusieurs morceaux associés entre eux.As best seen in Figure 9, the link 95 is made from a blank 103 in the form of an arch. A bridge 104 connects the lamellae 101, 102 to the first end 97 of the link 95, while towards the second end 98 of the link the lamellae 101, 102 respectively have first 105 and second 106 free ends. Preferably the lamellae 101, 102 and the bridge 104 form a single piece. However it could have been planned several pieces associated with each other.

Lorsque le futur maillon 95 est à l'état d'ébauche 103, les lamelles 101, 102 sont parallèles entre elles. D'autre part, comme on le comprend à l'aide de la figure 10, l'ébauche 103 est sensiblement plane. Ainsi les lamelles 101, 102 et le pont 104 sont plats. De plus les lamelles 101, 102 et le pont 104 sont coplanaires.When the future link 95 is in the blank state 103, the lamellae 101, 102 are parallel to each other. On the other hand, as understood from Figure 10, the blank 103 is substantially planar. Thus the lamellae 101, 102 and the bridge 104 are flat. In addition, the lamellae 101, 102 and the bridge 104 are coplanar.

L'ébauche 103 est fabriquée de préférence à partir d'une feuille d'un alliage métallique. Par exemple un acier prévu pour la fabrication des ressorts convient très bien. Ainsi le maillon 95 comprend du métal. Cependant d'autres matériaux peuvent être envisagés, comme des plastiques.The blank 103 is preferably made from a sheet of a metal alloy. For example, a steel intended for the manufacture of springs is very suitable. Thus the link 95 comprises metal. However, other materials may be considered, such as plastics.

La feuille donne aux lamelles 101, 102 et au pont 104 la même épaisseur. La largeur de chaque lamelle est sensiblement plus grande que l'épaisseur. Par exemple chaque lamelle 101, 102 présente une section rectangulaire.The sheet gives the slats 101, 102 and bridge 104 the same thickness. The width of each lamella is substantially larger than the thickness. For example, each lamella 101, 102 has a rectangular section.

Le maillon 95 formé est montré seul à la figure 11. Il est obtenu par la jonction, et la solidarisation l'une à l'autre, des extrémités respectives 105, 106 des lamelles 101, 102.The link 95 formed is shown alone in FIG. 11. It is obtained by joining and securing to each other respective ends 105, 106 of the lamellae 101, 102.

Comme le montre la figure 12, la solidarisation des lamelles 101, 102 est réalisée par exemple par poinçonnage. Après superposition des extrémités 105, 106 des lamelles 101, 102, un poinçon pousse la matière constitutive de la deuxième extrémité 106 à travers la première extrémité 105. En même temps qu'il pousse la matière, le poinçon perce les extrémités 105, 106 des lamelles 101, 102. Ensuite une forme replie la matière de la deuxième extrémité 106 de l'autre côté de la première extrémité 105.As shown in Figure 12, the joining of the slats 101, 102 is carried out for example by punching. After superposing the ends 105, 106 of the lamellae 101, 102, a punch pushes the constituent material of the second end 106 through the first end 105. At the same time that it pushes the material, the punch pierces the ends 105, 106 of the lamellae 101, 102. Then a shape folds the material of the second end 106 on the other side of the first end 105.

Bien entendu cette technique n'est pas limitative, et alternativement il pourrait être prévu par exemple un soudage, un collage, une liaison comprenant une pièce complémentaire, ou autre.Of course this technique is not limiting, and alternatively it could be provided for example a welding, gluing, a connection comprising a complementary part, or other.

Après solidarisation, les extrémités 105, 106 des lamelles 101, 102 sont à plat l'une sur l'autre. Les lamelles 101, 102 du maillon 95 sont directement liées au niveau de la deuxième extrémité 98, alors qu'elles sont séparées par le pont 104 au niveau de la première extrémité 97. Le parallélisme des lamelles 101, 102 s'estompe dans un sens d'éloignement du pont 104. Il s'ensuit que l'ébauche 103, qui est sensiblement plane, donne naissance à un maillon 95 courbe. Plus précisément le maillon 95 est naturellement courbé à la fois longitudinalement et transversalement. La courbure peut prendre deux états stables différents.After joining, the ends 105, 106 of the slats 101, 102 are flat on one another. The lamellae 101, 102 of the link 95 are directly connected at the level of the second end 98, while they are separated by the bridge 104 at the first end 97. The parallelism of the lamellae 101, 102 is faded in one direction. It follows that the blank 103, which is substantially flat, gives rise to a curved link 95. More precisely the link 95 is naturally curved both longitudinally and transversely. The curvature can take two different stable states.

Un premier état stable est présenté à l'aide des figures 13 et 15. Le maillon 95 présente une première courbure transversale par rapport à un plan de référence A, ainsi qu'une première courbure longitudinale par rapport à un plan de référence B. Etant donné que le maillon 95 est apposé à la bande 96, cette dernière prend sensiblement la courbure du maillon. Il peut s'agir par exemple d'une situation de couverture d'un pied ou d'une chaussure.A first stable state is presented with the aid of FIGS. 13 and 15. The link 95 has a first transverse curvature with respect to a reference plane A, as well as a first longitudinal curvature with respect to a reference plane B. Etant Since the link 95 is affixed to the band 96, the latter substantially takes the curvature of the link. This may be for example a cover situation of a foot or a shoe.

Une situation inverse est présentée à l'aide des figures 14 et 15. Cette situation peut être obtenue selon une manipulation de l'utilisateur, pour dégager un passage pour le pied ou la chaussure. Dans ce cas le maillon 95 présente une deuxième courbure transversale par rapport au plan de référence A, ainsi qu'une deuxième courbure longitudinale par rapport au plan de référence B. Bien entendu les deuxièmes courbures transversale et longitudinale, qui correspondent au deuxième état stable, se font dans un sens opposé aux premières.An opposite situation is presented with the help of figures 14 and 15. This situation can be obtained according to a manipulation of the user, to clear a passage for the foot or the shoe. In this case the link 95 has a second transverse curvature with respect to the reference plane A, and a second longitudinal curvature with respect to the reference plane B. Of course the second transverse and longitudinal curvatures, which correspond to the second stable state, are in a direction opposite to the first.

Le passage de l'un à l'autre des états peut se faire manuellement, ou par toute autre action. Bien entendu, rien n'empêche à la deuxième portion 80 d'adopter d'autres courbures que celles prises naturellement sous l'influence du maillon.The transition from one to the other states can be done manually, or by any other action. Of course, nothing prevents the second portion 80 from adopting other curvatures than those taken naturally under the influence of the link.

De préférence le passage de l'un à l'autre des états stables se fait par une déformation élastique du maillon 95. Cela signifie que les lamelles 101, 102 se déforment sans que la limite élastique du matériau qui les constitue soit dépassée, ni même atteinte. La structure du maillon 95 rend le moyen d'ajustement déformable élastiquement. Ainsi, le passage d'une courbure à l'autre de la deuxième portion 80 se fait de manière très perceptible par l'utilisateur.Preferably the transition from one to the other stable states is by elastic deformation of the link 95. This means that the lamellae 101, 102 deform without the elastic limit of the material constituting them is exceeded, or even reached. The structure of the link 95 makes the adjustment means elastically deformable. Thus, the passage of a curvature to the other of the second portion 80 is very noticeable by the user.

Bien entendu le maillon 95 aurait pu être réalisé autrement, par exemple par un moulage en forme d'une matière plastique.Of course the link 95 could have been achieved otherwise, for example by a molding in the shape of a plastic material.

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 exemples de réalisation ci-avant décrits, et comprend tous les variantes pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiments described above, and includes all variants that fall within the scope of the claims that follow.

En particulier il peut être prévu tout autre structure ou lieu d'implantation pour le moyen d'ajustement de la courbure d'une portion de lien.In particular, any other structure or location may be provided for the means for adjusting the curvature of a link portion.

L'invention peut être mise en oeuvre quel que soit le nombre de portions comprises par le lien.The invention can be implemented regardless of the number of portions included by the link.
