Abstract

The chassis for an in line roller skate has a base with front (3) and rear (4) supports for the boot, each forming an inverted U-shaped cross section. The end sections of the supports extend downwardly to be connected to two cheeks (7,8) with holes for the wheels. The front and rear supports are connected by a bridge piece (10) which resists torsional distortion of the skate.

Description

L'invention se rapporte au domaine du patin en ligne. Il concerne plus particulièrement un châssis amélioré pour la pratique du patin en ligne.The invention relates to the field of inline skating. he relates more particularly to an improved chassis for the inline skating.

Le patin en ligne présente habituellement un assemblage de plusieurs éléments fondamentaux dont une chaussure qui est fixée sur un châssis qui lui-même supporte une série de roues alignées. Le châssis forme donc l'interface entre la chaussure et les roues. Le châssis comprend généralement des ponts recevant la chaussure ; ces ponts reliant des parois latérales servant de support aux roues. Le châssis supporte les efforts de flexion et de torsion qui sont appliqués par le patineur. Il doit donc présenter des caractéristiques de rigidité suffisantes pour maintenir un alignement correct des roues à la fois selon le plan horizontal et le plan vertical pour éviter l'affaissement, le vrillage ou encore la déformation latérale lors des prises de virage.The inline skate usually presents an assembly of several fundamental elements including a shoe that is fixed on a chassis which itself supports a series of wheels aligned. The chassis therefore forms the interface between the shoe and the wheels. The chassis usually includes bridges receiving the shoe; these bridges connecting side walls serving as a support for the wheels. The chassis supports the efforts of flexion and torsion which are applied by the skater. he must therefore have rigidity characteristics sufficient to maintain correct alignment of the wheels at the times according to the horizontal plane and the vertical plane to avoid sagging, twisting or lateral deformation when cornering.

Il existe actuellement différents types de châssis. Les châssis les plus rigides mais aussi les plus chers à fabriquer sont les châssis extrudés et usinés à partir d'un profilé métallique, généralement en aluminium. On obtient ainsi une pièce monobloc d'une grande rigidité qui est particulièrement adaptée à la pratique de la compétition. Le procédé pour fabriquer de tels châssis est décrit dans le brevet US 5.388.846, par exemple. En dehors du coût, d'autres inconvénients sont liés au caractère monolithique du châssis qui donne peu de possibilités de moduler les caractéristiques mécaniques et rend le châssis peu amortissant.There are currently different types of chassis. The the most rigid chassis but also the most expensive to manufacture are the frames extruded and machined from a profile metallic, usually aluminum. We thus obtain a monobloc piece of great rigidity which is particularly adapted to the practice of competition. The process for manufacturing such chassis is described in the US patent 5,388,846, for example. Besides the cost, others disadvantages are linked to the monolithic nature of the chassis which gives few possibilities to modulate the characteristics mechanical and makes the chassis not very shock absorbing.

Le document EP-A-774 283 divulgue un châssis comprenant des flasques latéraux séparés obtenus par emboutissage de tôles puis reliés par des ponts. La rigidité désirée est donnée par une nervure du châssis de dimension et de localisation déterminée. La réalisation d'un tel châssis reste cependant d'un coût assez élevé compte tenu des opérations de mise en forme et de la consommation importante d'aluminium.Document EP-A-774 283 discloses a chassis comprising separate side plates obtained by stamping sheet metal then connected by bridges. The desired stiffness is given by a frame rib of dimension and location determined. The realization of such a chassis remains however of a fairly high cost taking into account the implementation operations significant form and consumption of aluminum.

On connaít bien aussi les châssis formés de deux demipièces en matière plastique injectée reliées entre elles par des moyens complémentaires d'assemblage. En général, ces châssis sont les plus économiques à fabriquer mais en contrepartie ils ont des caractéristiques mécaniques médiocres.We also know the chassis formed of two half-pieces of injected plastic connected together by additional assembly means. In general, these chassis are the most economical to manufacture but in in return they have poor mechanical characteristics.

Le document WO 98/33565 A1 concerne un patin en ligne comprenant une pièce d'interface disposée entre le châssis et la chaussure. La pièce d'interface est reliée sur le côté du châssis par des points de connexion situés entre les axes de roue et les ponts du châssis. Cette construction a pour avantage d'améliorer le transfert des forces entre la chaussure et le châssis. Une telle construction est toutefois compliquée et coûteuse à réaliser car elle nécessite la conception d'une pièce d'interface supplémentaire et un châssis entier en métal. Les surépaisseurs créées entre le châssis et l'interface ont aussi tendance à surélever la chaussure par rapport à une construction traditionnelle ; ce qui n'est pas souhaitable. Ces surépaisseurs augmentent aussi le coût matière et alourdissent le patin.WO 98/33565 A1 relates to an inline skate comprising an interface piece disposed between the chassis and the shoe. The interface piece is connected on the side of the chassis by connection points located between the axes of wheel and chassis bridges. This construction has for advantage of improving the transfer of forces between the shoe and the chassis. Such a construction is however complicated and expensive to carry out because it requires the design of a additional interface part and an entire metal chassis. The extra thicknesses created between the chassis and the interface have also tend to elevate the shoe over a traditional construction; which is not desirable. These extra thickness also increases the material cost and weighs down skate.

Le document EP-A1-795 347 enseigne un châssis comprenant deux blocs espacés longitudinalement reliés entre eux par des rails latéraux coulissants. Une telle construction autorise le réglage en longueur du châssis en fonction des différentes tailles de chaussure. Toutefois, un tel châssis présente une rigidité médiocre due à la conception en deux blocs séparés du châssis.Document EP-A1-795,347 teaches a chassis comprising two blocks spaced longitudinally connected together by sliding side rails. Such a construction allows the chassis length adjustment according to the different shoe sizes. However, such a chassis has a poor stiffness due to the design in two separate blocks of the frame.

Le document US 5.775.706 se rapporte à un assemblage de patin comprenant une chaussure, un châssis ayant des éléments de renfort croisés et une paire d'équerres de renfort reliant les axes avant et arrière du châssis aux côtés de la chaussure. Une telle construction favorise la transmission des efforts de la chaussure aux roues. Néanmoins, cette construction présente les inconvénients d'être d'une réalisation et d'un montage complexe. De plus, une telle construction n'est pas adaptée pour être associée à un système de démontage rapide de la chaussure sur le châssis.Document US 5,775,706 relates to an assembly of skate comprising a shoe, a frame having elements cross braces and a pair of bracing braces connecting the front and rear axes of the chassis alongside the shoe. Such a construction promotes the transmission of the forces of the shoe on the wheels. However, this construction presents the disadvantages of being a production and an assembly complex. In addition, such a construction is not suitable to be associated with a quick disassembly system of the shoe on the chassis.

Le document WO 97/33665 concerne un châssis pour articles de sport de glisse dont la structure comprend des parties réalisées à partir de matériaux aux caractéristiques mécaniques différentes rapportées l'une sur l'autre au moins partiellement. WO 97/33665 relates to a frame for articles board sports whose structure includes parts made from materials with mechanical characteristics different reported on each other at least partially.

Le document US 5.803.466 se rapporte à un patin en ligne comprenant un châssis muni d'une plaque en pointe et d'une plaque en talon de la chaussure auxquelles sont rattachés de manière détachable des flasques latéraux indépendants. Les flasques sont insérés au travers de deux cavités latéralement espacées et délimitées de chaque côté du châssis par deux paires de rebords s'étendant vers le bas à partir de la face inférieure de chaque plaque. L'un des avantages principaux est de pouvoir séparer les flasques du reste du châssis pour les remplacer ou les interchanger. Un autre avantage est de proposer une construction avec des plaques intermédiaires qui favorisent la distribution de poids de façon à renforcer la rigidité et la résistance du châssis. Cependant, une telle construction ne procure pas des caractéristiques mécaniques optimales du fait que les flasques sont simplement maintenus par des rebords et sont indépendamment bloqués au moyen de vis indépendantes. De plus, le montage d'un tel châssis apparaít long et peu économique du fait du nombre important d'éléments, notamment des pièces de fixation.Document US 5,803,466 relates to an inline skate comprising a chassis fitted with a pointed plate and a heel plate of the shoe to which are attached detachable way of independent lateral flanges. The flanges are inserted through two cavities laterally spaced and delimited on each side of the chassis by two pairs of ledges extending downward from the face bottom of each plate. One of the main advantages is to be able to separate the flanges from the rest of the chassis for the replace or interchange. Another advantage is propose a construction with intermediate plates which promote weight distribution so as to strengthen the rigidity and strength of the chassis. However, such construction does not provide mechanical characteristics optimal because the flanges are simply held by flanges and are independently blocked with screws independent. In addition, the mounting of such a chassis appears long and not very economical due to the large number of elements, including fasteners.

D'autres conceptions variées de châssis sont décrites dans les documents suivants : UK 18.312 ; US 578.081 ; US 593.278 ; US 2.168.820 ; US 3.387.852 ; US 5.380.020 ; WO 96/22818 ; US 5.549.310 ; WO 97/02072 ; DE 296 12 212 U1 et WO 96/26775. Pour autant, toutes ces constructions se différencient nettement de celle proposée par la présente invention.Other various chassis designs are described in the following documents: UK 18,312; US 578,081; US 593,278; US 2,168,820; US 3,387,852; US 5,380,020; WO 96/22818; US 5,549,310; WO 97/02072; DE 296 12 212 U1 and WO 96/26775. However, all these constructions are different clearly from that proposed by the present invention.

L'invention vise donc à proposer une structure de châssis qui réponde aux problèmes de l'art antérieur venant d'être évoqués.The invention therefore aims to propose a chassis structure which responds to the problems of the prior art which have just been mentioned.

En particulier, l'un des objets de l'invention est de proposer un châssis ayant de bonnes caractéristiques mécaniques, en particulier une bonne résistance et une bonne rigidité en torsion et flexion, et favorisant une transmission optimale des efforts lors de la pratique du patinage.In particular, one of the objects of the invention is to offer a chassis with good characteristics mechanical, in particular good resistance and good torsional and bending stiffness, and promoting transmission optimal effort during skating.

Un autre objet de l'invention est de proposer un châssis dont la conception même permet de moduler les caractéristiques mécaniques en faisant varier la nature des matériaux et les dimensions des éléments le constituant.Another object of the invention is to provide a chassis whose very design allows the characteristics to be modulated mechanical by varying the nature of the materials and the dimensions of the constituent elements.

Un autre objet de l'invention est de proposer un châssis ayant de bonnes caractéristiques mécaniques tout en limitant à la fois le nombre d'éléments participant à la construction, de même que l'encombrement, et limitant aussi l'utilisation de matières premières coûteuses et en les réservant aux endroits les plus appropriés.Another object of the invention is to provide a chassis having good mechanical characteristics while limiting to both the number of elements participating in the construction, same as the size, and also limiting the use of expensive raw materials and reserving them in places the most appropriate.

Un autre objet de l'invention est de proposer un châssis qui est susceptible de s'adapter à tout système d'accouplement de chaussure, en particulier, à tout système d'accouplement détachable.Another object of the invention is to provide a chassis which is capable of adapting to any coupling system shoe, in particular, to any coupling system detachable.

Un autre objet de l'invention est de proposer un châssis de conception à la fois légère et sans surépaisseur mais à la fois rigide et peu coûteuse.Another object of the invention is to provide a chassis design that is both light and without extra thickness but at the same time both rigid and inexpensive.

Un autre objet de l'invention est de proposer un châssis d'assemblage facile nécessitant un minimum d'opérations.Another object of the invention is to provide a chassis easy to assemble requiring a minimum of operations.

Un autre objet de l'invention est d'offrir la possibilité de faciliter l'adaptation du châssis à plusieurs tailles de chaussures et ainsi donc, de limiter le nombre de pièces à fabriquer et ainsi réduire les coûts de fabrication.Another object of the invention is to offer the possibility to facilitate the adaptation of the chassis to several sizes of shoes and so therefore, limit the number of pieces to manufacture and thus reduce manufacturing costs.

Pour cela, l'invention concerne un châssis de patin en ligne du type constitué par un corps principal comprenant une base transversale munie d'au moins une surface de support en pointe de chaussure et une surface de support en talon de chaussure, chacune d'elles formant un pont avant et un pont arrière en forme de U en se prolongeant vers le bas, soit par deux portions latérales de projection sur lesquelles sont rapportés deux flasques indépendantes parallèles aptes à recevoir une série de roues, soit directement par lesdits flasques lorsque ceux-ci forment une pièce monolithique avec une partie supérieure transversale de liaison, caractérisé en ce que les surfaces de support de pointe et de talon de la chaussure sont reliées entre elles par une arche intermédiaire pour constituer une base anti-torsion du châssis et un élément de transmission des efforts.For this, the invention relates to a skate frame in line of the type constituted by a main body comprising a transverse base provided with at least one support surface in shoe tip and heel support surface shoe, each of which forms a front bridge and a bridge U-shaped rear extending downward, either by two lateral projection portions on which are reported two independent parallel flanges suitable for receive a series of wheels, either directly by said flanges when these form a monolithic piece with a transverse upper connecting part, characterized in what the toe and heel support surfaces of the shoe are interconnected by an intermediate arch to constitute an anti-twist base of the chassis and an element transmission of forces.

Selon une seconde caractéristique de l'invention, les surfaces de support de talon et de pointe forment des plans d'appui sensiblement horizontaux, et sont reliés entre eux solidairement par une arche qui est réalisée globalement selon un arc convexe s'étendant longitudinalement, pour former un sous-ensemble monobloc apte à être solidarisé à des flasques latéraux par tout moyen de liaison, en vue de former ledit châssis.According to a second characteristic of the invention, the heel and toe support surfaces form planes substantially horizontal support, and are interconnected jointly and severally by an arch which is generally carried out according to a convex arc extending longitudinally, to form a monobloc sub-assembly capable of being secured to flanges lateral by any connecting means, in order to form said frame.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to characteristics which will emerge during the description which will follow, and which should be considered in isolation or according to all their possible technical combinations.

    • Le châssis 1 de l'invention est constitué par un corps principal 2 comprenant une base supérieure transversale munie d'au moins une surface de support en pointe 3, - ou surface de support avant 3, d'une chaussure (non représentée) et une surface de support en talon 4, - ou surface de support arrière 4 de la même chaussure, chacune d'elle formant un pont avant et un pont arrière reliant entre eux deux flasques respectivement 7, 8 du châssis et comportant à cet effet une forme de U se prolongeant vers le bas.The chassis 1 of the invention consists of a body main 2 comprising a transverse upper base provided at least one support surface at point 3, - or surface of front support 3, a shoe (not shown) and a heel support surface 4, - or rear support surface 4 of the same shoe, each of them forming a front bridge and a rear axle connecting two flanges to each other respectively 7, 8 of the chassis and comprising for this purpose a U shape extending down.

    Selon le présent exemple des figures 1 à 3, ces prolongements sont obtenus par deux portions latérales de projection verticale 5 et 6 sur lesquelles sont rapportés les deux flasques indépendants parallèles 7 et 8 aptes à recevoir une série de roues (non représentées), les roues étant fixées grâce à des axes traversant des trous 9 desdits flasques 7 et 8.According to the present example of FIGS. 1 to 3, these extensions are obtained by two lateral portions of vertical projection 5 and 6 on which the two independent parallel flanges 7 and 8 able to receive a series of wheels (not shown), the wheels being fixed by means of axes passing through holes 9 of said flanges 7 and 8.

    Comme il sera décrit plus loin, la prolongation des supports de talon et de pointe en direction verticale peuvent également être obtenus directement par les flasques lorsque ceux-ci forment une pièce monolithique avec une partie supérieure transversale de liaison.As will be described later, the extension of heel and toe supports in vertical direction can also be obtained directly by the flanges when these form a monolithic piece with a part upper transverse link.

    De même, les supports avant et arrière 3, 4 peuvent être constitués par des blocs parallélipipèdiques de hauteur suffisante pour la fixation des flasques.Similarly, the front and rear supports 3, 4 can be consisting of parallelepipedic blocks of height sufficient for fixing the flanges.

    Selon une caractéristique commune à tous les modes de réalisation représentés, les surfaces de support de pointe 3 et de talon 4 de la chaussure sont reliées entre elles par une arche 10 intermédiaire, pour constituer une barre anti-torsion du châssis et un élément de transmission des efforts.According to a characteristic common to all the modes of shown embodiment, the tip support surfaces 3 and of the heel 4 of the shoe are interconnected by a arch 10 intermediate, to constitute an anti-torsion bar of the chassis and a force transmission element.

    En fait, les surfaces de support de talon 4 et de pointe 3 forment des plans d'appui sensiblement horizontaux éventuellement décalés en hauteur, c'est-à-dire situés à des niveaux différents, et sont reliés entre eux solidairement par une arche longitudinale 10, cette arche 10 est de préférence réalisée globalement selon un arc convexe s'étendant longitudinalement, pour former un sous-ensemble monobloc apte à être solidarisé aux flasques 7 et 8 par tout moyen de liaison, en vue de former ledit châssis 1. Elle peut également avoir une forme tout à fait rectiligne, l'essentiel étant qu'elle forme une poutre de liaison des surfaces de support 3, 4 et de rigidification en torsion du châssis.In fact, the heel support surfaces 4 and toe 3 form substantially horizontal support planes possibly offset in height, that is to say located at different levels, and are interconnected by a longitudinal arch 10, this arch 10 is preferably generally performed in a convex arc extending longitudinally, to form a one-piece sub-assembly suitable for be secured to the flanges 7 and 8 by any connecting means, in order to form said chassis 1. It can also have a forms quite straight, the main thing being that it forms a beam connecting the support surfaces 3, 4 and torsional stiffening of the chassis.

    Toujours selon l'exemple de réalisation des figures 1, 2 et 3, les flasques 7 et 8 sont rapportés de part et d'autre des faces externes d'un U inversé formé par les portions latérales de projection 5, 6, et sont donc reliés entre eux par l'arche 10 et les supports avant et arrière 3, 4.Still according to the embodiment of Figures 1, 2 and 3, the flanges 7 and 8 are attached to both sides of the external faces of an inverted U formed by the lateral portions projection 5, 6, and are therefore interconnected by the arch 10 and the front and rear supports 3, 4.

    Le mode de réalisation des figures 4 et 5 diffère essentiellement du précédent en ce que les flasques 7A, 8A sont rapportés sur les faces internes du U formées par les faces internes des portions latérales de projection 5A, 6A et les supports avant et arrière 3A, 4A sont reliés entre eux par l'arche 10A.The embodiment of Figures 4 and 5 differs essentially from the previous one in that the flanges 7A, 8A are reported on the internal faces of the U formed by the faces internal of the lateral projection portions 5A, 6A and the front and rear supports 3A, 4A are interconnected by the arch 10A.

    Le mode de réalisation représenté sur les figures 6 et 7 diffère essentiellement de celui représenté sur les figures 1 à 3 en ce que les flasques 7B, 8B sont rapportés de part et d'autre des faces externes d'un U inversé formé par les portions latérales de projection verticale 5B, 6B des supports avant et arrière 3B, 4B, reliés entre eux par l'arche 10B. Les surfaces de support supérieures desdits supports 3B, 4B débordent horizontalement des flasques 7B, 8B de part et d'autre de ceux-ci pour permettre une adaptation à des chaussures élargies.The embodiment shown in Figures 6 and 7 essentially differs from that shown in Figures 1 to 3 in that the flanges 7B, 8B are added in part and on the other side of an inverted U formed by the vertical projection side portions 5B, 6B of the supports front and rear 3B, 4B, interconnected by the arch 10B. The upper support surfaces of said supports 3B, 4B project horizontally from the side plates 7B, 8B and other of these to allow adaptation to enlarged shoes.

    Selon les exemples de réalisation précités, l'arche 10, 10A, 10B est réalisée selon un profil en U inversé dont les branches libres sont dirigées vers le bas. Elle peut également être constituée par un profilé de forme différente et comportant des nervures de rigidification transversales.According to the abovementioned exemplary embodiments, the arch 10, 10A, 10B is produced according to an inverted U-shaped profile, the free branches are directed downwards. She can also be formed by a profile of different shape and comprising transverse stiffening ribs.

    Cette arche constitue en fait un pont longitudinal reliant les supports avant 3 et arrière 4 et constituant une barre de rigidification anti-torsion et de transmission des efforts entre l'avant et l'arrière.This arch in fact constitutes a longitudinal bridge connecting the front 3 and rear 4 supports and constituting a anti-torsion stiffening and force transmission between front and back.

    L'exemple de réalisation représenté sur les figures 8 et 9 diffère essentiellement des précédents en ce que les flasques 7C, 8C sont rapportés de part et d'autre des faces externes des branches verticales d'un U formant l'arche 10C. Lesdites branches verticales sont dirigées vers le haut pour se prolonger, dans la zone du talon 4 et de la pointe 3 de la chaussure, par des ailes horizontales 10Ca et 10Cb en saillie vers l'extérieur selon une forme de Ω inversé, pour constituer les surfaces de support correspondantes 3C, 4C de la chaussure, reliées entre elles par ladite arche 10C.The embodiment shown in Figures 8 and 9 essentially differs from the previous ones in that the flanges 7C, 8C are attached on either side of the external faces of the vertical branches of a U forming the arch 10C. Said vertical branches are directed upward to extend, in the area of the heel 4 and the toe 3 of the shoe, by projecting horizontal wings 10Ca and 10Cb outwards in an inverted Ω form, to form the corresponding support surfaces 3C, 4C of the shoe, interconnected by said arch 10C.

    L'avantage offert par cette variante est de pouvoir obtenir l'arche 10C et ses supports d'extrémité 3C, 4C par frappe au cours d'une opération d'emboutissage.The advantage offered by this variant is to be able obtain the arch 10C and its end supports 3C, 4C by strikes during a stamping operation.

    Le mode de réalisation des figures 10 et 11 diffère essentiellement de celui des figures 8 et 9 en ce que l'ensemble arche 10D - support talon 4 et pointe 3 est fixé sur un berceau ou semelle sensiblement rigide 11 de la chaussure, l'arche 10D étant sensiblement rectiligne, afin d'épouser le plan du berceau 11 et ainsi rigidifier à la fois celui-ci et les flasques 7D, 8D pour une efficacité maximum.The embodiment of Figures 10 and 11 differs essentially that of FIGS. 8 and 9 in that the arch 10D assembly - heel support 4 and toe 3 is fixed on a substantially rigid cradle or sole 11 of the shoe, the arch 10D being substantially rectilinear, in order to marry the plane of the cradle 11 and thus stiffen both the latter and 7D, 8D flanges for maximum efficiency.

    Selon tous les exemples de réalisation qui viennent d'être cités, les flasques 7 et 8 ou 7A, 8A ou 7B, 8B ou 7C, 8C ou 7D, 8D sont obtenus avantageusement par emboutissage. Bien entendu d'autres modes d'obtention peuvent également être prévus en fonction des matériaux utilisés. Egalement d'une manière générale, les moyens de liaison de ces flasques sur les supports avant et arrière 3, 4, 3A, 4A, 3B, 4B, 3C, 4C, 3D, 4D, sont effectués par l'intermédiaire de rivets latéraux 12 constituant les moyens de liaison précités.According to all of the exemplary embodiments which have just been cited, the flanges 7 and 8 or 7A, 8A or 7B, 8B or 7C, 8C or 7D, 8D are advantageously obtained by stamping. Of course other methods of production can also be provided in depending on the materials used. Also in a way general, the means of connection of these flanges on the front and rear supports 3, 4, 3A, 4A, 3B, 4B, 3C, 4C, 3D, 4D, are made via side rivets 12 constituting the aforementioned connecting means.

    La variante de réalisation représentée sur les figures 12 et 13 diffère essentiellement des précédentes en ce que les flasques 7E, 8E constituent une pièce monolithique avec des parties supérieures de liaison transversales avant 13 et arrière 14 selon une configuration en U inversé. Dans ce cas, les surfaces de support supérieures de talon et de pointe 4E, 3E reliées par l'arche 10E, sont rapportées sur lesdites parties transversales avant 13 et arrière 14 par tout moyen de liaison connu en soi.The variant embodiment shown in Figures 12 and 13 differs essentially from the previous ones in that the flanges 7E, 8E constitute a monolithic part with upper transverse connecting parts before 13 and rear 14 in an inverted U configuration. In that case, the upper heel and toe support surfaces 4E, 3E connected by the arch 10E, are reported on said front 13 and rear 14 transverse parts by any means of link known per se.

    Selon cette variante, ces moyens de liaison peuvent être constitués par des rivets 15 engagés verticalement par le dessus du châssis, ou encore par des vis. According to this variant, these connecting means can be constituted by rivets 15 engaged vertically by the above the chassis, or by screws.

    Toujours selon ce mode de réalisation, le châssis formé par les flasques 7E, 8E et leurs parties transversales 13 et 14 est obtenu par extrusion et usinage ultérieur.Still according to this embodiment, the chassis formed by the flanges 7E, 8E and their transverse parts 13 and 14 is obtained by extrusion and subsequent machining.

    Toujours selon ce mode de réalisation des figures 12 et 13, le support de talon 4E de la chaussure est d'une épaisseur 〈〈 e 〉〉 supérieure à l'épaisseur 〈〈 e' 〉〉 du support de pointe 4E 〈〈 e' 〉〉 de manière à procurer une rigidification et une surélévation du talon de la chaussure.Still according to this embodiment of FIGS. 12 and 13, the heel support 4E of the shoe is of a thickness 〈〈 e 〉〉 greater than the thickness 〈〈 e '〉〉 of the tip support 4E 〈〈 e '〉〉 so as to provide stiffening and heightening of the heel of the shoe.

    Dans ce cas, la filière d'extrusion du profilé à la base du châssis est simplifiée puisque les parties transversales 13, 14 sont alignées. Lesdites parties 13, 14 peuvent également être prévues à des niveaux différents dans le profilé d'extrusion.In this case, the extrusion die from the profile to the base of the chassis is simplified since the transverse parts 13, 14 are aligned. Said parts 13, 14 can also be provided at different levels in the profile extrusion.

    Bien entendu, l'arche 10E peut être à la fois montée à l'intérieur sur l'arrière du châssis, et à l'extérieur sur l'avant de ce même châssis, ou inversement.Of course, the arch 10E can be both mounted at inside on the back of the chassis, and outside on the front of this same chassis, or vice versa.

    Comme le montre la figure 14, les supports de pointe 3 et de talon 4 en liaison avec l'arche 10 peuvent être obtenus au cours d'une même opération de découpe d'une barre extrudée 20 de profil correspondant.As shown in Figure 14, the tip supports 3 and heel 4 in connection with the arch 10 can be obtained at during the same cutting operation of an extruded bar 20 corresponding profile.

    Egalement selon un perfectionnement de l'invention, l'arche 10 de liaison des supports de pointe 3 et de talon 4 est dissymétrique pour s'associer à une empreinte de pied.Also according to an improvement of the invention, the arch 10 for connecting the toe 3 and heel 4 supports is asymmetrical to associate with a footprint.

    La figure 15 représente un exemple de conformation se rapportant aux vues schématiques du mode de réalisation des figures 4 et 5, et montrent un exemple particulier de forme pouvant être donnée à une arche 10A selon un des modes de réalisation de l'invention. Dans ce cas, l'arche 10A est également profilée en direction transversale pour une rigidité en torsion encore plus importante.Figure 15 shows an example of conformation relating to schematic views of the embodiment of Figures 4 and 5, and show a particular example of shape can be given to an arch 10A according to one of the modes of realization of the invention. In this case, the arch 10A is also profiled in transverse direction for rigidity in even greater torsion.

    C'est précisément là également un avantage important procuré par l'invention que de permettre de décliner à l'infini la forme de cette arche et par conséquent du châssis, permettant ainsi d'enrichir la gamme de produits sur la base. Cette arche et les supports avant arrière pouvant être obtenus par moulage, injection d'une matière métallique ou plastique. Il pourra s'agir d'aluminium, de carbone, de toute matière plastique ou même de titanium ou magnésium. Lorsqu'il s'agit de matière plastique, celle-ci pourra être chargée de fibres de manière à obtenir un renforcement du matériau.This is also an important advantage. procured by the invention that allow to infinitely decline the shape of this arch and therefore of the chassis, thus enriching the range of products on the base. This arch and the front rear supports obtainable by molding, injection of a metallic or plastic material. It could be aluminum, carbon, any material plastic or even titanium or magnesium. When it comes to plastic, it can be loaded with fibers so as to obtain a reinforcement of the material.

    Cet élément pourra également être obtenu par usinage d'une barre extrudée comme déjà évoqué et représenté à la figure 14.This element can also be obtained by machining a extruded bar as already mentioned and shown in Figure 14.

    La variante de réalisation représentée sur la figure 16 diffère essentiellement des précédentes en ce que la liaison des supports de talon 4F et de pointe 3F s'effectue par l'intermédiaire des flasques 7F, 8F qui se prolongent transversalement l'un vers l'autre à leur partie supérieure centrale A-B sans se rejoindre, pour former l'arche 10F.The variant embodiment shown in FIG. 16 essentially differs from the previous ones in that the binding heel supports 4F and toe 3F is carried out by through the flanges 7F, 8F which extend transversely towards each other at their upper part central A-B without joining, to form the arch 10F.

    En fait, dans les exemples précédents, il s'agissait d'obtenir une arche formant une barre de torsion longitudinale par un pont longitudinal, alors que dans ce dernier cas la barre de torsion est constituée par un pont transversal formant ladite arche 10F.In fact, in the previous examples, it was to obtain an arch forming a longitudinal torsion bar by a longitudinal bridge, whereas in the latter case the torsion bar is constituted by a transverse bridge forming said arch 10F.

    Le réglage de la torsion pourra être effectué par une vis de réglage 16 traversant les deux parties constituant cette arche 10F.The adjustment of the torsion can be carried out by a screw adjustment 16 crossing the two parts constituting this arch 10F.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation ainsi décrits, et englobe tous les modes de réalisation mettant en oeuvre des moyens techniques similaires ou équivalents.Of course, the invention is not limited to the modes of embodiment thus described, and encompasses all the modes of realization using similar technical means or equivalent.
