Abstract

The skate comprises a chassis (1) having wheels (4) and a boot (5) fixed to it. The boot has a supple lower upper (10) and a rigid back (12). The front part of the upper has an opening (11) for the passage of the foot and laces (20) for fastening the boot. A rigid collar (13) which surrounds the user's ankle is pivoted on the back near the upper end (10a) so as to freely pivot frontwards independently of the upper. The rigid collar is located at the level of natural pivoting of the leg on the foot. The collar is provided at the rear with a notch (13a) for facilitating its rearward rotation.

Description

La présente invention a pour objet un patin à roulettes, et plus spécifiquement un patin du type à roues en ligne.The present invention relates to a roller skate, and more specifically a skate of the in-line wheel type.

Les patins à roulettes de ce type, dérivés de la pratique du patin à glace, sont habituellement constitués d'une tige haute formant une coque en matière synthétique rigide s'étendant jusqu'à la cheville et surmontée d'un collier également en matière synthétique rigide entourant la jambe du patineur pour la stabilité latérale ou transversale de celle-ci, et fixée sur la tige par deux axes d'articulation latéraux.Roller skates of this type, derived from the practice of ice skating, usually consist of a high rod forming a shell of rigid synthetic material extending to the ankle and surmounted by a collar also of synthetic material rigid surrounding the skater's leg for lateral or transverse stability, and fixed to the rod by two lateral articulation axes.

De tels patins présentent l'inconvénient d'être "chauds" et de ne fournir aucune aération du pied, d'où une importante transpiration, surtout lorsque le patinage est effectué sous des températures extérieures élevées.Such skates have the drawback of being "hot" and of not providing any ventilation for the foot, hence significant perspiration, especially when skating is carried out under high outside temperatures.

Ces patins sont également inconfortables du fait de la rigidité de la coque et du collier constituant la tige et empêchant tout mouvement de la cheville par rapport au pied, une telle rigidité étant souhaitée pour un maintien optimum de la cheville par rapport au pied.These pads are also uncomfortable due to the rigidity of the shell and of the collar constituting the rod and preventing any movement of the ankle relative to the foot, such rigidity being desired for optimum support of the ankle relative to the foot.

Le but de la présente invention est donc de fournir un patin pourvu d'une chaussure améliorée, résolvant à la fois des problèmes de confort et de ventilation du pied, tout en conservant la stabilité transversale et maintien de la cheville nécessaires.The object of the present invention is therefore to provide a skate provided with an improved shoe, solving both problems of comfort and ventilation of the foot, while retaining the transverse stability and ankle support required.

Ce but est atteint, selon l'invention, par le fait que la chaussure comporte une tige basse en matériau souple, et munie d'un contrefort arrière en matière rigide, et en ce qu'elle comporte un collier rigide apte à entourer la cheville de l'utilisateur, et articulé sur le contrefort de la tige, à l'extrémité supérieure de cette demière de façon à pouvoir pivoter librement d'avant en arrière, et au moins vers l'avant, par rapport à ladite tige.This object is achieved, according to the invention, by the fact that the shoe comprises a low rod made of flexible material, and provided with a rear buttress made of rigid material, and in that it comprises a rigid collar capable of surrounding the ankle of the user, and articulated on the buttress of the rod, at the upper end of the latter so as to be able to pivot freely from front to rear, and at least towards the front, relative to said rod.

Une telle disposition permet une indépendance totale en rotation du collier par rapport à la tige, et donc une grande liberté de flexion avant/arrière de la jambe, tout en offrant la tenue de pied et la stabilité transversale pied/cheville nécessaire.Such an arrangement allows complete independence in rotation of the collar with respect to the rod, and therefore great freedom of front / rear flexion of the leg, while providing the foot support and the necessary transverse foot / ankle stability.

Par ailleurs, cette liberté de rotation du collier autorise une plus grande extension en hauteur de celui-ci et permet donc une meilleure tenue latérale de la jambe/cheville.Furthermore, this freedom of rotation of the collar allows a greater extension in height of the latter and therefore allows better lateral holding of the leg / ankle.

Selon une forme de réalisation avantageuse, l'articulation du collier rigide sur la tige est située sensiblement au niveau des malléoles. De ce fait, l'articulation du collier correspond sensiblement à l'articulation naturelle de la jambe sur le pied, et il n'y a pas de décalage entre les axes de ces articulations.According to an advantageous embodiment, the articulation of the rigid collar on the rod is located substantially at the level of the malleoli. Therefore, the articulation of the collar corresponds substantially to the natural articulation of the leg on the foot, and there is no offset between the axes of these articulations.

De toute façon, l'invention sera mieux comprise et d'autres caractéristiques de celle-ci seront mises en évidence à l'aide de la description qui suit en référence au dessin schématique annexé en représentant à titre d'exemples non limitatifs plusieurs formes de réalisation et dans lequel :

  • la figure 1 est une vue en de côté de la chaussure selon l'invention,
  • la figure 2 est une vue en coupe longitudinale partielle d'un détail de la figure 1,
  • la figure 3 est une vue en coupe partielle selon III-III de la figure 1,
  • la figure 4 est une perspective d'une chaussure selon un autre mode de réalisation.
In any case, the invention will be better understood and other characteristics thereof will be highlighted with the aid of the description which follows with reference to the appended schematic drawing, representing by way of nonlimiting examples several forms of realization and in which:
  • FIG. 1 is a side view of the shoe according to the invention,
  • FIG. 2 is a view in partial longitudinal section of a detail in FIG. 1,
  • FIG. 3 is a partial sectional view along III-III of FIG. 1,
  • Figure 4 is a perspective of a shoe according to another embodiment.

Le patin représenté sur la figure 1 est constitué d'un châssis 1 de section transversale en forme de U et constitué de deux flasques latéraux 2 sur lesquels sont fixées les roues 4, et d'une platine de montage 3 sur laquelle est fixée, par sa semelle 6, la chaussure 5.The shoe shown in FIG. 1 consists of a chassis 1 of U-shaped cross section and consists of two lateral flanges 2 on which the wheels 4 are fixed, and a mounting plate 3 on which is fixed, by its sole 6, the shoe 5.

La chaussure 5 présente extérieurement l'allure d'une chaussure basse normale, et est donc constituée d'une tige souple basse 10, c'est-à-dire d'une tige dont les parties rigides ne s'étendent pas en hauteur au-delà des malléoles, munie sur sa partie avant d'une ouverture 11 pour le passage du pied et d'un système de laçage 20 de type connu en soi, pour la fermeture de la chaussure et le serrage du pied.The shoe 5 has the appearance of a normal low shoe on the outside, and therefore consists of a low flexible rod 10, that is to say of a rod whose rigid parts do not extend in height at beyond the malleoli, provided on its front part with an opening 11 for the passage of the foot and with a lacing system 20 of a type known per se, for closing the shoe and tightening the foot.

La tige 10 est munie au niveau du talon d'un contrefort arrière rigide 12 pouvant être réalisé de toute façon connue en soi, et constituant en fait la seule partie rigide de la tige.The rod 10 is provided at the heel with a rigid rear buttress 12 which can be produced in any way known per se, and which in fact constitutes the only rigid part of the rod.

Ce contrefort 12 est de préférence réalisé en matière synthétique rigide, et s'étend sur toute la partie arrière de la chaussure, tout autour du talon de celle-ci.This buttress 12 is preferably made of rigid synthetic material, and extends over the entire rear part of the shoe, all around the heel thereof.

Ce contrefort 12 s'étend, dans la zone des malléoles, jusqu'en haut de la tige, pour la réception d'un collier articulé 13, et présente extérieurement au niveau de ces malléoles un bossage 12a en saillie vers l'extérieur s'étendant sensiblement perpendiculairement à la paroi du contrefort.This buttress 12 extends, in the region of the malleoli, up to the top of the rod, for the reception of an articulated collar 13, and has externally at the level of these malleoli a boss 12a projecting outwards. extending substantially perpendicular to the wall of the buttress.

Chaque bossage 12a est par ailleurs muni d'un trou 12b pour le montage articulé du collier 13 au moyen de clous 19 (cf. fig. 4).Each boss 12a is also provided with a hole 12b for the articulated mounting of the collar 13 by means of nails 19 (cf. fig. 4).

Ces clous 19 servent d'arrêt au collier 13 tandis que les bossages 12a matérialisent l'axe de rotation 30 de ce collier sur la tige.These nails 19 serve to stop the collar 13 while the bosses 12a materialize the axis of rotation 30 of this collar on the rod.

On notera que les clous 19 peuvent être remplacés par tous autres modes de liaison permettant une rotation tels que des rivets. Cependant, l'utilisation de clous 19 est particulièrement avantageuse car elle permet une pose par simple application d'une pression, sans nécessiter de contre-pièce comme dans le cas de rivets, ce qui permet de simplifier notablement la fabrication puisque le collier peut alors être posé dans la dernière phase de fabrication de la chaussure.It will be noted that the nails 19 can be replaced by any other connection mode allowing rotation such as rivets. However, the use of nails 19 is particularly advantageous because it allows installation by simple application of pressure, without the need for a counterpiece as in the case of rivets, which makes it possible to simplify manufacture considerably since the collar can then be placed in the last shoe manufacturing phase.

Par ailleurs, les clous 19 seront avantageusement constitués en un matériau relativement souple par rapport à un rivet en métal, tel que du delrin de façon que leur tête 19a suive les déformations éventuelles du collier rigide 13, par exemple lors d'une torsion de la jambe, une telle construction permettant d'éviter l'arrachement de ces clous lors d'une telle torsion.Furthermore, the nails 19 will advantageously be made of a relatively flexible material with respect to a metal rivet, such as delrin so that their head 19a follows any deformations of the rigid collar 13, for example during a twisting of the leg, such a construction making it possible to avoid the tearing of these nails during such a twist.

Bien entendu, le collier articulé 13 pourrait également être monté d'une autre façon en permettant le démontage facile, et par exemple par un système à baïonnette ou par encliquetage connus en soi et non décrits ci-après, pour le chargement du collier ou l'utilisation de la chaussure avec une simple tige basse.Of course, the articulated collar 13 could also be mounted in another way allowing easy disassembly, and for example by a bayonet system or by snap-fastening known per se and not described below, for loading the collar or the use of the shoe with a simple low rod.

Le collier articulé 13 est constitué par une manchette en matériau rigide et notamment en un matériau synthétique tel que du pebax.The articulated collar 13 is constituted by a cuff made of rigid material and in particular of a synthetic material such as pebax.

Ce collier 13 s'étend vers le haut jusqu'au bas du mollet et entoure tout le bas de jambe. Il est ouvert à sa partie avant pour permettre la mise en place du pied dans la chaussure et est muni de moyens de serrage 15 de type connu en soi, et constitués par exemple par des moyens autoagrippants.This collar 13 extends up to the bottom of the calf and surrounds the entire lower leg. It is open at its front part to allow the foot to be placed in the shoe and is provided with clamping means 15 of a type known per se, and constituted for example by hook-and-loop means.

Ce collier 13 est par ailleurs muni à l'arrière d'une échancrure 13a destinée à faciliter la rotation vers l'arrière de ce collier (cf. position en pointillés sur la figure 1).This collar 13 is also provided at the rear with a notch 13a intended to facilitate the rearward rotation of this collar (cf. position in dotted lines in FIG. 1).

Ainsi qu'on le concevra aisément, la hauteur importante du collier 13 permet une excellente tenue latérale de la jambe lors de la pratique du patin, une telle hauteur permettant en outre une plus grande répartition sur la jambe des efforts de réaction et par conséquent un meilleurs confort pour l'utilisateur.As will be readily appreciated, the large height of the collar 13 allows excellent lateral holding of the leg during the practice of the skate, such a height also allowing a greater distribution over the leg of the reaction forces and consequently a better user comfort.

Cependant, cette hauteur du collier 13 ne gêne pas les mouvements de flexion avant/arrière de la jambe par rapport au pied, et peut même être augmentée, par exemple, jusqu'à mi-jambe de façon à diminuer les efforts sur la jambe.However, this height of the collar 13 does not hinder the front / rear bending movements of the leg relative to the foot, and can even be increased, for example, up to the mid-leg so as to reduce the forces on the leg.

En effet, l'articulation totale et indépendante du collier 13 sur la tige permet à celui-ci de pivoter librement sans aucune limitation en flexion par la tige et sans aucune gêne pour l'utilisateur. D'ailleurs, la languette 22 de la chaussure ne s'étend, en hauteur, pas au-delà du pli de flexion du pied de l'utilisateur de façon à ne pas en gêner la flexion, ni gêner le pivotement du collier.Indeed, the total and independent articulation of the collar 13 on the rod allows it to pivot freely without any limitation in bending by the rod and without any discomfort for the user. Moreover, the tongue 22 of the shoe does not extend, in height, not beyond the flexion fold of the foot of the user so as not to interfere with the flexion, or interfere with the pivoting of the collar.

De façon surprenante, une telle liberté de mouvement de la cheville s'est avérée non préjudiciable au maintien latéral de la cheville pour la pratique de ce type de patinage, tout en offrant un confort nettement amélioré et sans aucun point dur par rapport aux chaussures de patin traditionnelles. Par ailleurs, la structure souple de la tige de la chaussure, réalisée de préférence en un matériau textile aéré, permet d'éviter les problèmes de transpiration liés à l'utilisation des matières plastiques "non respirantes", et offre donc un double confort, tant au niveau de l'aération que du serrage du pied effectué à l'aide de parties souples. Dans une telle construction, la semelle 6 très rigide participe aussi à la tenue du pied.Surprisingly, such freedom of movement of the ankle has been found not to be detrimental to the lateral support of the ankle for the practice of this type of skating, while offering markedly improved comfort and without any hard point compared to footwear. traditional skate. Furthermore, the flexible structure of the upper of the shoe, preferably made of an aerated textile material, makes it possible to avoid the problems of perspiration linked to the use of "non-breathable" plastics, and therefore offers double comfort, both in terms of ventilation and tightening of the foot using flexible parts. In such a construction, the very rigid sole 6 also participates in holding the foot.

Pour augmenter encore le confort d'un tel patin, et ainsi que le montre la figure 2, le collier 13 est muni intérieurement d'une doublure 16 destinée au confort de la jambe et interrompue dans la zone 13a de recouvrement de la partie basse du collier 13 et de la partie haute 10a de la tige 10, de façon à éviter toute surépaisseur au niveau de cette zone. La partie confort du collier est donc "embarquée" sur celui-ci de sorte que son pivotement ne peut pas être gêné par une partie confort issue de la tige. On notera que dans le cas représenté, la partie extrême supérieure 10a de la tige s'étend en fait légèrement au-dessus du contrefort arrière 12, et donc au-dessus des malléoles, pour assurer une certaine continuité de la tige/collier, mais une telle construction n'est pas gênante puisque cette partie 10a n'est pas rigide et est destinée uniquement au confort. Une telle partie 10a ne gêne donc en rien la flexion de la jambe et pourrait tout aussi bien être supprimée.To further increase the comfort of such a skate, and as shown in FIG. 2, the collar 13 is internally provided with a lining 16 intended for the comfort of the leg and interrupted in the area 13a of overlap of the lower part of the collar 13 and the upper part 10a of the rod 10, so as to avoid any excess thickness in this area. The comfort part of the collar is therefore "on-board" on the latter so that its pivoting cannot be hindered by a comfort part coming from the rod. Note that in the case shown, the upper end portion 10a of the rod actually extends slightly above the rear buttress 12, and therefore above the malleoli, to ensure a certain continuity of the rod / collar, but such a construction is not troublesome since this part 10a is not rigid and is intended only for comfort. Such a part 10a therefore does not hinder the flexion of the leg in any way and could just as easily be eliminated.

Bien évidemment, et pour des raisons de confort, la doublure 16 est conçue de façon à s'étendre dans la continuité de la surface interne de la tige.Obviously, and for reasons of comfort, the lining 16 is designed so as to extend in continuity with the internal surface of the rod.

Sur la figure 4 est représenté un patin similaire à celui de la figure 1, et pour lequel les mêmes éléments seront désignés par les mêmes références.In Figure 4 is shown a shoe similar to that of Figure 1, and for which the same elements will be designated by the same references.

Les seules différences entre ce patin et celui représenté précédemment réside dans la prévision sur la chaussure d'une applique 17 et d'un organe de rappel 25 du collier.The only differences between this skate and the one shown above resides in the provision on the shoe of an applique 17 and a return member 25 of the collar.

Ainsi que le montre cette figure 4, l'applique 17 est constituée de deux parties 17a, 17b s'étendant respectivement sur le dessus de la tige en recouvrant le système de laçage, et sur le devant du bas de jambe de façon à obturer l'ouverture définie par le collier 13 pour des raisons d'étanchéité.As shown in this figure 4, the wall lamp 17 consists of two parts 17a, 17b extending respectively over the top of the rod covering the lacing system, and on the front of the lower leg so as to close off the opening defined by the collar 13 for sealing reasons.

Ces deux parties d'applique 17a, 17b sont reliées l'une à l'autre par une couture 18 formant une charnière de façon à préserver la flexibilité de la chaussure et à ne pas gêner le pivotement du collier, la partie d'applique 17b pouvant pivoter par rapport à la partie d'applique 17a solidairement avec le collier.These two applique parts 17a, 17b are connected to each other by a seam 18 forming a hinge so as to preserve the flexibility of the shoe and not to hinder the pivoting of the collar, the applique part 17b can pivot relative to the wall portion 17a integrally with the collar.

Ainsi que le montre la figure 4, la partie d'applique 17a peut, de façon connue en soi, être ouverte en deux parties au moyen d'une fermeture 21 de type à glissière pour permettre l'accès au système de laçage 20 de la chaussure.As shown in Figure 4, the wall portion 17a can, in a manner known per se, be opened in two parts by means of a closure 21 of the slide type to allow access to the lacing system 20 of the shoe.

L'organe de rappel 25 du collier 13 est, dans l'exemple représenté, constitué par une épingle double comportant deux branches, l'une 26 supérieure en appui contre le bord inférieur 13b du collier, et l'autre inférieure 27 en appui contre une face de butée associée 31 du contrefort arrière 12 de la tige.The return member 25 of the collar 13 is, in the example shown, constituted by a double pin comprising two branches, one upper 26 bearing against the lower edge 13b of the collar, and the other lower 27 bearing against an associated abutment face 31 of the rear buttress 12 of the rod.

L'épingle 25 est par ailleurs passée autour des axes d'articulation 19 du collier pour son maintien en place.The pin 25 is also passed around the hinge pins 19 of the collar to hold it in place.

Cette épingle est sollicitée lors d'un pivotement du collier vers l'arrière à partir d'une position d'équilibre médiane sensiblement verticale de celui-ci, qui est matérialisée par l'axe O-O' sur la figure, et exerce donc lors d'un tel pivotement du collier un effort de rappel de ce collier vers l'avant.This pin is stressed during a pivoting of the collar backwards from a substantially vertical median equilibrium position thereof, which is materialized by the axis OO 'in the figure, and therefore exerts during 'such a pivoting of the collar an effort to return this collar forward.

Par conséquent, le pivotement du collier vers l'avant est totalement libre, tandis que son pivotement vers l'arrière s'exerce à l'encontre de l'organe élastique 25 qui facilite par contre le retour vers l'avant dudit collier.Consequently, the pivoting of the collar towards the front is completely free, while its pivoting towards the rear is exerted against the elastic member 25 which on the other hand facilitates the return towards the front of said collar.

Bien entendu, l'organe de rappel élastique 25 pourrait être réalisé d'une toute autre façon, l'essentiel étant qu'il exerce un effort de rappel sur le collier lors d'un pivotement de celui-ci vers l'arrière. Il pourrait par exemple s'agir d'un ressort de type différent, ressort à spire, tampon élastique,...etc. Cet organe élastique pourrait également être conçu comme faisant partie intégrante de l'un des éléments de la tige, et pourrait ainsi être constitué par une branche élastique issue du collier articulé et coopérant avec une butée prévue sur le contrefort arrière, ou une autre partie de la tige 10. A l'inverse, il pourrait également s'agir d'une branche élastique issue du contrefort arrière de la tige et coopérant avec une butée associée du collier.Of course, the elastic return member 25 could be produced in a completely different way, the main thing being that it exerts a return force on the collar during a pivoting of the latter towards the rear. It could for example be a spring of a different type, coil spring, elastic buffer, etc. This elastic member could also be designed as an integral part of one of the elements of the rod, and could thus be constituted by an elastic branch coming from the articulated collar and cooperating with a stop provided on the rear buttress, or another part of the rod 10. Conversely, it could also be an elastic branch coming from the rear buttress of the rod and cooperating with an associated stop of the collar.

Dans tous les cas, une telle disposition tend à assister le muscle jambier qui commande le relèvement de la pointe du pied par rapport à la jambe, et permet donc de limiter la fatigue de celui-ci lors de la pratique du sport.In all cases, such an arrangement tends to assist the leg muscle which controls the raising of the ball of the foot relative to the leg, and therefore makes it possible to limit the fatigue thereof when practicing sport.

Un autre avantage important de cet organe de rappel élastique est qu'il fournit une sorte d'appui arrière à résistance progressive à la jambe du sportif, et surtout qu'il procure à ce dernier un référencement vers l'arrière de la position de sa jambe, c'est-à-dire qu'il lui permet de situer la position de sa jambe par rapport à la verticale, information particulièrement importante pour le maintien de l'équilibre dans un tel sport de glisse.Another important advantage of this elastic return member is that it provides a sort of rear support with progressive resistance to the athlete's leg, and above all that it gives the latter a rearward referencing of the position of his leg, that is to say it allows him to locate the position of his leg relative to the vertical, particularly important information for maintaining balance in such a sliding sport.

Bien entendu, la présente invention n'est pas limitée aux exemples de réalisation décrits ci-avant, mais englobe tous les modes de réalisation similaires ou équivalents.Of course, the present invention is not limited to the exemplary embodiments described above, but encompasses all similar or equivalent embodiments.
