Description

Patin à roues en ligne Inline skating
L'invention se rapporte au domaine des patins à roues et concerne plus particulièrement les patins à roues en ligne.The invention relates to the field of roller skates and relates more particularly to inline skates.
Les patins à roues en ligne, ou "patins en ligne", ont des roues généralement situées toutes dans un même plan longitudinal du patin, et tournent chacune autour d'un axe propre sensiblement perpendiculaire au plan longitudinal du patin, les axes étant parallèles entre eux.Inline skates, or "inline skates", have wheels generally located all in the same longitudinal plane of the skate, and each rotate around a proper axis substantially perpendicular to the longitudinal plane of the skate, the axes being parallel between them.
On peut distinguer deux familles principales de patins en ligne : une première famille dans laquelle chaque axe de roue est immobilisé par rapport au patin, et une seconde dans laquelle au moins un axe de roue est mobile par rapport au patin de préférence dans un sens de rapprochement ou d'éloignement du pied d'un utilisateur.We can distinguish two main families of inline skates: a first family in which each wheel axle is immobilized relative to the skate, and a second in which at least one wheel axle is movable relative to the skate preferably in a direction of moving the foot closer or further away from a user.
Dans la première famille, les roues sont montées sur le patin de façon réglable ou non. Une ligne de contact, définie par la courbe enveloppe des points de contact de l'extrémité inférieure de chaque roue avec le sol, a une forme droite ou convexe en fonction de l'implantation ou des réglages choisis.In the first family, the wheels are mounted on the pad in an adjustable manner or not. A contact line, defined by the curve enveloping the points of contact of the lower end of each wheel with the ground, has a straight or convex shape depending on the location or the chosen settings.
Quelle que soit la forme de cette ligne de contact, la conduite du patin par l'utilisateur se fait selon un mode de tout ou rien. Lorsqu'une impulsion donnée par l'utilisateur amène une ou plusieurs roues au contact du sol, la conduite du patin est effective soit dans un sens moteur, soit dans un sens de freinage. Par contre, si un mouvement de l'utilisateur éloigne le patin du sol, alors la conduite du patin n'a pas lieu.Whatever the shape of this contact line, the driving of the skate by the user is done in an all or nothing mode. When an impulse given by the user brings one or more wheels into contact with the ground, the skate is driven either in a driving direction or in a braking direction. On the other hand, if a movement of the user moves the shoe away from the ground, then the driving of the shoe does not take place.
Dans la seconde famille, la mobilité d'une ou plusieurs roues par rapport au patin permet d'amortir des chocs ou de répartir les efforts de contact sur les différentes roues quand l'utilisateur donne des impulsions de conduite.In the second family, the mobility of one or more wheels relative to the shoe makes it possible to absorb shocks or to distribute the contact forces on the different wheels when the user gives driving impulses.
Cependant, les patins selon ces deux familles ne permettent pas à l'utilisateur d'être à l'aise dans toutes les configurations.However, the skates according to these two families do not allow the user to be comfortable in all configurations.
En effet, ces patins ne sont pas capables d'assurer un bon contact de toutes les roues au sol quand l'utilisateur donne des impulsions de conduite, en particulier au début et à la fin de chaque impulsion. II s'ensuit que la précision de conduite n'est bonne ni au début ni à la fin des phases d'impulsion, ce qui engendre des risques de chute.Indeed, these pads are not capable of ensuring good contact of all the wheels on the ground when the user gives driving impulses, in particular at the start and at the end of each impulse. It follows that the driving precision is good neither at the beginning nor at the end of the pulse phases, which generates risks of falling.
D'autre part, ces patins ne sont pas non plus à même de restituer de l'énergie provenant des efforts de conduite ou de chocs éventuels, que ce soit lors d'une impulsion de conduite ou lors d'une impulsion d'appui, en particulier pour l'appel de sauts. Par conséquent, les performances sont insuffisantes notamment en termes de vitesse, d'accélération, et de hauteur de saut.On the other hand, these pads are also not able to restore energy from driving forces or possible shocks, whether during a driving pulse or during a pressing pulse, especially for calling jumps. Consequently, the performances are insufficient in particular in terms of speed, acceleration, and jump height.
Un objet de l'invention est de remédier à ces inconvénients en proposant un patin dont la stabilité au sol est continue et sensiblement constante pendant la durée d'une phase d'impulsion.An object of the invention is to remedy these drawbacks by proposing a shoe whose stability on the ground is continuous and substantially constant for the duration of a pulse phase.
Un autre objet de l'invention est de proposer un patin capable d'accumuler et de restituer de l'énergie emmagasinée pendant l'utilisation du patin.Another object of the invention is to provide a skate capable of accumulating and returning energy stored during the use of the skate.
Un objet de l'invention encore est de faire un patin souple dans la conduite, confortable, et capable de filtrer des vibrations résultant d'un état de surface imparfait du sol.Another object of the invention is to make a flexible pad in the pipe, comfortable, and capable of filtering vibrations resulting from an imperfect surface condition of the ground.
Pour cela, un patin à roues selon l'invention comprend un châssis de liaison entre au moins deux roues et une semelle de chaussure, le châssis comprenant au moins un moyen de maintien des roues à distance constante les unes des autres, et au moins une platine solidaire de la semelle.For this, a wheeled skate according to the invention comprises a connection chassis between at least two wheels and a shoe sole, the chassis comprising at least one means for keeping the wheels at constant distance from each other, and at least one plate secured to the sole.
Le patin à roues selon l'invention est caractérisé par le fait que le moyen de maintien des roues et la platine sont mobiles l'un par rapport à l'autre.The roller skate according to the invention is characterized in that the means for holding the wheels and the plate are movable relative to each other.
Cette disposition permet à toutes les roues de rester en contact avec le sol, dans des cas où la semelle fait des petits mouvements autour d'une position d'équilibre. En particulier, lorsqu'une impulsion est donnée avec le pied, l'effort exercé sur les roues n'est généralement pas constant dans le temps. La mobilité relative de l'ensemble des roues et de la platine permet avantageusement de conserver une bonne ligne de contact avec le sol, et garantit une bonne stabilité du pied de l'utilisateur.This arrangement allows all the wheels to remain in contact with the ground, in cases where the sole makes small movements around an equilibrium position. In particular, when an impulse is given with the foot, the force exerted on the wheels is generally not constant over time. The relative mobility of all of the wheels and of the plate advantageously makes it possible to maintain a good line of contact with the ground, and guarantees good stability of the user's foot.
De préférence, le moyen de maintien des roues à distance constante les unes des autres est une poutre mobile dans un plan longitudinal sensiblement perpendiculaire à la semelle.Preferably, the means for keeping the wheels at a constant distance from each other is a beam that can move in a longitudinal plane substantially perpendicular to the sole.
Selon l'invention, tout déplacement relatif de la poutre par rapport à la semelle se fait, de préférence, par coopération avec au moins un moyen élastique. Cette structure permet au patin d'accumuler une énergie qu'il peut restituer par exemple à la fin d'une impulsion de conduite ou de saut. L'avantage est que les performances de l'utilisateur sont nettement améliorées sans qu'il ait à fournir des efforts supplémentaires. De préférence, dans un patin selon l'invention, au moins un moyen d'amortissement est inséré entre la poutre et la semelle. Le comportement du patin en est avantageusement encore amélioré notamment en souplesse d'utilisation.According to the invention, any relative movement of the beam relative to the sole is preferably done by cooperation with at least one elastic means. This structure allows the skate to accumulate energy which it can restore, for example at the end of a driving or jumping pulse. The advantage is that the performance of the user is significantly improved without having to make additional efforts. Preferably, in a skate according to the invention, at least one damping means is inserted between the beam and the sole. The behavior of the skate is advantageously further improved in particular in terms of flexibility of use.
D'autres caractéristiques et avantages de l'invention seront mieux compris à l'aide de la description qui va suivre, en regard du dessin annexé illustrant, par des exemples non limitatifs, comment l'invention peut être réalisée et dans lequel :Other characteristics and advantages of the invention will be better understood with the aid of the description which follows, with reference to the appended drawing illustrating, by non-limiting examples, how the invention can be implemented and in which:

- la figure 10 est une coupe selon X-X de la figure 9.- Figure 10 is a section along X-X of Figure 9.
Un mode de réalisation privilégié d'un patin à roues 1 selon l'invention apparaît à la figure 1 selon une vue latérale, qui correspond ici à un pied droit d'un utilisateur.A preferred embodiment of a roller skate 1 according to the invention appears in Figure 1 in a side view, which here corresponds to a right foot of a user.
Le patin 1 est maintenu au pied non représenté de l'utilisateur au moyen d'une chaussure 2 reliée à des roues 10, 1 1 , 12, 13, comme il va être décrit.The shoe 1 is held at the foot, not shown, of the user by means of a shoe 2 connected to wheels 10, 11, 12, 13, as will be described.
La chaussure 2 comprend une tige 3 solidaire d'une semelle 4. Une platine 5 prolonge la face inférieure 6 de la semelle 4 vers le bas pour former une arête longitudinale en relief sur cette face inférieure 6. Selon le mode de réalisation privilégié, la semelle 4 et la platine 5 forment une pièce unique réalisée par exemple par moulage d'une matière plastique. Comme il sera mieux montré par la suite, la platine 5 est creusée par une rainure longitudinale 7 qui permet de loger au moins un moyen de maintien des roues et au moins un moyen élastique.The shoe 2 comprises a rod 3 secured to a sole 4. A plate 5 extends the lower face 6 of the sole 4 downward to form a longitudinal edge in relief on this lower face 6. According to the preferred embodiment, the sole 4 and plate 5 form a single piece produced for example by molding a plastic material. As will be better shown hereinafter, the plate 5 is hollowed out by a longitudinal groove 7 which makes it possible to accommodate at least one means for holding the wheels and at least one elastic means.
Le moyen de maintien des roues, réalisé ici sous la forme d'une poutre 8 de section transversale en forme de U sur laquelle sont fixées les roues 10, 1 1 , 12, 13, permet de maintenir la roue arrière 10, les roues centrales 11 , 12 et la roue avant 13, à distance constante les unes des autres.The wheel retaining means, produced here in the form of a beam 8 of U-shaped cross section on which the wheels 10, 11, 12, 13 are fixed, makes it possible to maintain the rear wheel 10, the wheels central units 11, 12 and the front wheel 13, at a constant distance from each other.
Les roues 10, 1 1 , 12, 13 sont fixées de façon à être situées toutes dans un même plan longitudinal P du patin 1 , qui est sensiblement vertical quand l'utilisateur est en position orthostatique, et qui sera montré sur d'autres figures.The wheels 10, 1 1, 12, 13 are fixed so as to be located all in the same longitudinal plane P of the shoe 1, which is substantially vertical when the user is in the orthostatic position, and which will be shown in other figures .
Le moyen élastique, réalisé ici sous la forme d'une lame flexible 9, coopère avec la poutre 8, comme on va le voir, pour gérer la position de la poutre 8 par rapport à la platine 5.The elastic means, produced here in the form of a flexible blade 9, cooperates with the beam 8, as will be seen, to manage the position of the beam 8 relative to the plate 5.
La figure 2 montre la fixation de la roue arrière 10. La lame flexible 9 et la poutre 8 sont reliées ensemble au niveau de la roue arrière 10 par l'intermédiaire d'une chape 14 servant au montage de la roue 10. La chape 14 en forme de U est fixée sur une face inférieure 15 et à l'extrémité arrière 16 de la lame flexible 9. La roue 10 est montée libre en rotation autour d'un arbre 17 d'axe 18 fixé sur la chape 14, de façon connue de l'homme du métier, et peut donc tourner dans la chape 14. L'arbre 17 passe en même temps à travers un ensemble d'orifices, pratiqués dans des côtés 19, 20 de la chape 14 et dans des bras 21 , 22 de la poutre 8, de façon à assurer la liaison entre la chape 14 et la poutre 8. Deux couches 23, 24 de matériau viscoélastique sont insérées entre la chape 14 et la poutre 8.Figure 2 shows the attachment of the rear wheel 10. The flexible blade 9 and the beam 8 are connected together at the rear wheel 10 via a yoke 14 for mounting the wheel 10. The yoke 14 U-shaped is fixed on a lower face 15 and at the rear end 16 of the flexible blade 9. The wheel 10 is mounted free to rotate around a shaft 17 of axis 18 fixed on the yoke 14, so known to a person skilled in the art, and can therefore turn in the yoke 14. The shaft 17 passes at the same time through a set of orifices, made in the sides 19, 20 of the yoke 14 and in the arms 21, 22 of the beam 8, so as to ensure the connection between the yoke 14 and the beam 8. Two layers 23, 24 of viscoelastic material are inserted between the yoke 14 and the beam 8.
Cette disposition a l'avantage d'éliminer toutes les vibrations parasites qui peuvent perturber le fonctionnement du patin 1.This arrangement has the advantage of eliminating all the parasitic vibrations which can disturb the operation of the pad 1.
La rigidité de la chape 14 empêche toute désolidarisation de l'arbre 17, des bras 21 , 22 et des côtés 19, 20, qui sont immobilisés les uns par rapport aux autres dans un plan P1 parallèle au plan de coupe ll-ll de la figure 1 .The rigidity of the yoke 14 prevents any separation of the shaft 17, the arms 21, 22 and the sides 19, 20, which are immobilized with respect to each other in a plane P1 parallel to the cutting plane ll-ll of the figure 1 .
Par contre, comme il est montré à la figure 3, un déplacement relatif de la chape 14 et de la poutre 8 est possible dans un plan P2 parallèle au plan de coupe lll-lll de la figure 1.On the other hand, as shown in FIG. 3, a relative displacement of the yoke 14 and of the beam 8 is possible in a plane P2 parallel to the cutting plane III-III of FIG. 1.
En effet, si l'arbre 17 passe à travers les bras 21 , 22 de la poutre 8 par des orifices circulaires, il passe à travers les côtés 19, 20 de la chape 14 par des orifices oblongs en vis à vis, ou lumières 26, 27 de la chape 14. L'arbre 17 est donc à même de coulisser d'une extrémité à l'autre des lumières 26, 27 dans le plan de coupe lll-lll à rencontre des moyens viscoélastiques 23, 24, c'est-à-dire dans un sens sensiblement parallèle à la semelle 4.Indeed, if the shaft 17 passes through the arms 21, 22 of the beam 8 through circular orifices, it passes through the sides 19, 20 of the yoke 14 through oblong orifices opposite, or lights 26 , 27 of the yoke 14. The shaft 17 is therefore able to slide from one end to the other of the openings 26, 27 in the cutting plane lll-lll against viscoelastic means 23, 24, it is that is to say in a direction substantially parallel to the sole 4.
Au niveau de la roue avant 13, la lame flexible 9 et la poutre 8 sont reliées ensemble d'une façon presque identique à la liaison du côté de la roue arrière 10 par l'intermédiaire d'une chape 28 en forme de U fixée de façon commune sur la face inférieure 15 et à l'extrémité avant 29 de la lame flexible 9.At the front wheel 13, the flexible blade 9 and the beam 8 are connected together in a manner almost identical to the connection on the side of the rear wheel 10 by means of a U-shaped clevis 28 fixed in common on the underside 15 and at the front end 29 of the flexible blade 9.
La roue 13 est montée libre en rotation autour d'un arbre 30 d'axe 31 qui passe à travers un ensemble d'orifices tous circulaires de la chape avant 28 et des bras 21 , 22 de la poutre 8. Dans ce cas aucun mouvement relatif n'est donc possible entre la chape 28 et la poutre 8 que ce soit dans un sens du plan P1 parallèle au plan de coupe ll-ll ou dans un sens du plan P2 parallèle au plan de coupe lll-lll.The wheel 13 is mounted to rotate freely around a shaft 30 of axis 31 which passes through a set of all circular orifices of the front yoke 28 and of the arms 21, 22 of the beam 8. In this case, no movement relative is therefore not possible between the yoke 28 and the beam 8 whether in a direction of the plane P1 parallel to the cutting plane ll-ll or in a direction of the plane P2 parallel to the cutting plane lll-lll.
Les roues centrales 1 1 , 12 sont quant à elles reliées à la poutre 8 d'une façon conventionnelle qui apparaît par exemple en coupe à la figure 4. II s'agit ici de la roue 1 1 dont l'arbre de rotation est inséré dans deux orifices circulaires respectivement des bras 21 et 22 de la poutre 8.The central wheels 1 1, 12 are in turn connected to the beam 8 in a conventional manner which appears for example in section in Figure 4. This is here the wheel 1 1 whose rotation shaft is inserted in two circular orifices respectively of the arms 21 and 22 of the beam 8.
La figure 4 permet de voir la rainure longitudinale 7 de la platine 5, qui est de préférence sensiblement médiane par rapport au patin 1 , et dont le milieu est le plan longitudinal P. Les bras 21 et 22 de la poutre 8 sont en contact respectivement avec une paroi 32 et une paroi 33 de la rainure 7 ; cette structure permet à la rainure 7 de servir de guide à la poutre 8 qui peut se déplacer dans la rainure 7, de préférence dans une direction parallèle au plan longitudinal P et dans un sens de rapprochement ou d'éloignement de la tige 3. La lame flexible 9 est quant à elle solidarisée au fond de la rainure 7, sur une paroi 34, par au moins un moyen de retenue représenté ici sous forme de vis 35, 36.Figure 4 allows to see the longitudinal groove 7 of the plate 5, which is preferably substantially median relative to the shoe 1, and whose middle is the longitudinal plane P. The arms 21 and 22 of the beam 8 are in contact respectively with a wall 32 and a wall 33 of the groove 7; this structure allows the groove 7 to serve as a guide for the beam 8 which can move in the groove 7, preferably in a direction parallel to the longitudinal plane P and in a direction of approach or distancing of the rod 3. The flexible blade 9 is itself secured to the bottom of groove 7, on a wall 34, by at least one retaining means shown here in the form of screws 35, 36.
La lame flexible 9 est donc située dans une position sensiblement médiane du patin 1.The flexible blade 9 is therefore located in a substantially central position of the shoe 1.
Les moyens décrits ci-avant sont visibles simultanément sur la figure 5, qui est une coupe selon le plan P permettant d'expliciter le fonctionnement du patin 1.The means described above are visible simultaneously in FIG. 5, which is a section along the plane P making it possible to explain the operation of the pad 1.
La figure 5 montre comment le moyen élastique représenté sous la forme de la lame flexible 9 est deformable dans le plan longitudinal P de déplacement de la poutre 8, chaque extrémité 16, 29 de la lame 9 étant reliée à une extrémité de la poutre 8 tandis qu'une zone intermédiaire de la lame 9 est reliée à la semelle 4 ou à la platine 5.FIG. 5 shows how the elastic means shown in the form of the flexible blade 9 is deformable in the longitudinal plane P of movement of the beam 8, each end 16, 29 of the blade 9 being connected to one end of the beam 8 while that an intermediate zone of the blade 9 is connected to the sole 4 or to the plate 5.
La lame flexible 9 a de préférence une forme courbe dont les extrémités 16, 29 sont plus éloignées de la face inférieure 6 de la semelle 4 que ne l'est la zone intermédiaire. Les extrémités 16, 29 peuvent se déformer selon une valeur d'angle α du côté arrière et selon une valeur d'angle β du côté avant, sous l'effet de chocs ou d'impulsions transmis au patin 1 . Les déformations selon les valeurs d'angles α, β sont possibles parce qu'au moins l'une des extrémités 16, 29 de la lame 9 est mobile par rapport à la poutre 8, comme il a été expliqué. Les déformations se traduisent par des variations de distance entre la courbe enveloppe C, qui passe par chaque point des roues 10, 1 1 , 12, 13 apte à entrer en contact avec le sol, et la semelle 4 du patin 1.The flexible blade 9 preferably has a curved shape whose ends 16, 29 are more distant from the lower face 6 of the sole 4 than is the intermediate zone. The ends 16, 29 can deform according to an angle value α on the rear side and according to an angle value β on the front side, under the effect of shocks or pulses transmitted to skate 1. The deformations according to the values of angles α, β are possible because at least one of the ends 16, 29 of the blade 9 is movable relative to the beam 8, as has been explained. The deformations result in variations in distance between the envelope curve C, which passes through each point of the wheels 10, 11, 12, 13 capable of coming into contact with the ground, and the sole 4 of the shoe 1.
Les variations de distance peuvent par exemple être mesurées entre la courbe C et le fond 34 de la rainure 7. La figure 5 correspond à un cas où la courbe enveloppe C est droite, et où les roues 10, 1 1 , 12, 13 contactent un sol S linéaire. La distance h1 correspond à une position haute du patin 1 par rapport au sol S, tandis que la distance h2 correspond à une position basse. La position haute est une position naturelle dans laquelle la lame 9 n'est pas contrainte. Au contraire, la position basse traduit une accumulation d'énergie par déformation de la lame 9, énergie qui peut être restituée pour assurer un meilleur contact des roues 10, 11 , 12, 13 avec le sol S, ou pour aider l'utilisateur à effectuer des sauts.The variations in distance can for example be measured between the curve C and the bottom 34 of the groove 7. FIG. 5 corresponds to a case where the envelope curve C is straight, and where the wheels 10, 11, 12, 13 contact a linear S soil. The distance h1 corresponds to a high position of the shoe 1 relative to the ground S, while the distance h2 corresponds to a low position. The high position is a natural position in which the blade 9 is not constrained. On the contrary, the low position translates an accumulation of energy by deformation of the blade 9, energy which can be restored to ensure better contact of the wheels 10, 11, 12, 13 with the ground S, or to help the user to perform jumps.
Le patin 1 selon l'invention permet donc une meilleure conduite et facilite l'utilisation.The pad 1 according to the invention therefore allows better driving and facilitates use.
Les couches de matériau viscoélastique 23, 24, qui ont été insérées au niveau de la chape arrière 14, constituent une forme de réalisation d'un moyen d'amortissement agissant par frottement et/ou par déformation entre la chape 14 et donc la lame flexible 9 et la poutre 8.The layers of viscoelastic material 23, 24, which have been inserted at the level of the rear yoke 14, constitute an embodiment of a damping means acting by friction and / or by deformation between the yoke 14 and therefore the flexible blade 9 and beam 8.
En effet, chaque couche de matériau viscoélastique 23, 24 est située à une extrémité de la poutre 8 où la lame 9 et la poutre 8 sont mobiles l'une par rapport à l'autre, comme il a été expliqué.Indeed, each layer of viscoelastic material 23, 24 is located at one end of the beam 8 where the blade 9 and the beam 8 are movable relative to each other, as has been explained.
La réalisation du patin 1 peut être faite au moyen de tous les matériaux et techniques connus de l'homme de l'art.The realization of the pad 1 can be made using all the materials and techniques known to those skilled in the art.
En particulier, la lame flexible 9 peut être réalisée en matériaux composites ou en métal, ainsi que les chapes 14, 28 et la poutre 8.In particular, the flexible blade 9 can be made of composite materials or metal, as well as the yokes 14, 28 and the beam 8.
L'assemblage entre les chapes 14, 28 et la lame 9 peut se faire par collage, soudage ou tout moyen.The assembly between the yokes 14, 28 and the blade 9 can be done by gluing, welding or any means.
Le matériau viscoélastique peut être un caoutchouc, un polyuréthane ou autre.The viscoelastic material can be rubber, polyurethane or the like.
Ce mode de réalisation permet de contenir l'ensemble des éléments nécessaires au roulage à l'intérieur d'un espace dont la largeur n'excède pas celle de la rainure longitudinale 7. La structure est donc suffisamment fine pour permettre au patin 1 de s'incliner de manière conséquente dans un virage. On peut envisager d'autres modes de réalisation tel que celui montré aux figures 6, 7 et 8.This embodiment makes it possible to contain all the elements necessary for rolling inside a space whose width does not exceed that of the longitudinal groove 7. The structure is therefore sufficiently fine to allow the pad 1 to '' tilt steeply in a turn. One can envisage other embodiments such as that shown in FIGS. 6, 7 and 8.
Pour des raisons de commodité, on désigne les parties communes par des références identiques. Un patin 1 est visible à la figure 6 ; il présente une chaussure 2 composée d'une tige 3 solidarisée à une semelle 4. Une platine 5 prolonge la face inférieure 6 de la semelle 4, dans un sens d'éloignement de la tige 3, et selon une direction longitudinale du patin 1.For reasons of convenience, the common parts are designated by identical references. A shoe 1 is visible in Figure 6; it has a shoe 2 composed of a rod 3 secured to a sole 4. A plate 5 extends the lower face 6 of the sole 4, in a direction away from the rod 3, and in a longitudinal direction of the shoe 1.
Des roues arrière 10, centrales 11 , 12, et avant 13 sont maintenues ensemble par une poutre 8, elle-même guidée par rapport à la platine 5 au moyen d'une rainure longitudinale 7 et d'une lame flexible 9 montrées en coupe à la figure 7.Rear wheels 10, central 11, 12, and front 13 are held together by a beam 8, itself guided relative to the plate 5 by means of a longitudinal groove 7 and a flexible blade 9 shown in section at Figure 7.
La rainure 7 est sensiblement centrée sur un plan longitudinal P du patin 1. La poutre 8 comprend deux bras 21 et 22 qui sont en contact de parois 32 et 33 de la rainure 7. La poutre 8 est apte à se déplacer dans la rainure 7 dans un sens d'éloignement ou de rapprochement du fond 34 de la rainure 7. Les déplacements sont proportionnels aux déformations de la lame flexible 9 qui est elle-même montée dans une autre rainure 59, latérale et sensiblement parallèle à la rainure 7, et maintenue dans cette rainure latérale 59 par une goupille 40.The groove 7 is substantially centered on a longitudinal plane P of the shoe 1. The beam 8 comprises two arms 21 and 22 which are in contact with walls 32 and 33 of the groove 7. The beam 8 is able to move in the groove 7 in a direction of distance or approximation of the bottom 34 of the groove 7. The displacements are proportional to the deformations of the flexible blade 9 which is itself mounted in another groove 59, lateral and substantially parallel to the groove 7, and held in this lateral groove 59 by a pin 40.
La lame flexible 9 est donc située dans une position sensiblement latérale du patin 1.The flexible blade 9 is therefore located in a substantially lateral position of the shoe 1.
La poutre 8 et la lame 9 sont reliées ensemble au niveau de leurs extrémités respectives.The beam 8 and the blade 9 are connected together at their respective ends.
La figure 7 montre que la liaison du côté avant du patin 1 se fait par un arbre 41 d'axe 42 commun à la roue 13, à la poutre 8 et à la lame 9. L'arbre 41 passe par des orifices tous circulaires de la lame 9, des bras 21 et 22, et de la roue 13.FIG. 7 shows that the connection on the front side of the shoe 1 is made by a shaft 41 of axis 42 common to the wheel 13, to the beam 8 and to the blade 9. The shaft 41 passes through all circular orifices of blade 9, arms 21 and 22, and wheel 13.
Autrement dit, la lame 9 et la poutre 8 sont articulées l'une par rapport à l'autre du côté avant du patin 1 sans possibilité de translation. Par contre, la liaison est différente du côté arrière du patin 1. En effet, si un arbre 17 d'axe 18 passe en même temps par des orifices de la lame 9, d'une couche de matériau viscoélastique 23, de la roue 10, et des bras 21 , 22 de la poutre 8, tous ces orifices sont circulaires à l'exception du trou oblong ou lumière 43 de la lame 9.In other words, the blade 9 and the beam 8 are articulated relative to each other on the front side of the pad 1 without the possibility of translation. On the other hand, the connection is different from the rear side of the shoe 1. In fact, if a shaft 17 of axis 18 passes at the same time through orifices of the blade 9, of a layer of viscoelastic material 23, of the wheel 10 , and of the arms 21, 22 of the beam 8, all of these orifices are circular with the exception of the oblong or light hole 43 of the blade 9.
II s'ensuit qu'un déplacement relatif est possible entre la lame 9 et la poutre 8 dans un sens sensiblement parallèle à la semelle 4. Chaque extrémité arrière 16 ou avant 29 de la lame 9 peut donc se déformer d'une valeur d'angle α ou β sous l'effet de chocs ou d'impulsions.It follows that a relative movement is possible between the blade 9 and the beam 8 in a direction substantially parallel to the sole 4. Each rear 16 or front 29 end of the blade 9 can therefore be deformed by an angle value α or β under the effect of shocks or pulses.
Le fonctionnement de l'ensemble est similaire à celui du mode de réalisation préalablement décrit.The operation of the assembly is similar to that of the embodiment previously described.
De façon complémentaire, des moyens de retenue maintiennent la lame 9 sur les arbres des roues avant 13 et arrière 10. Ces moyens sont par exemple un anneau élastique 44 associé à une gorge de l'arbre 41 à l'avant du patin 1 , et un anneau élastique 45 associé à une gorge de l'arbre 17 à l'arrière du patin 1 ; l'anneau élastique 45, ainsi que la couche de matériau viscoélastique 23 interposée entre la poutre 8 et la lame 9, sont visibles sur la figure 8.In a complementary manner, retaining means hold the blade 9 on the shafts of the front 13 and rear wheels 10. These means are for example an elastic ring 44 associated with a groove in the shaft 41 at the front of the pad 1, and an elastic ring 45 associated with a groove in the shaft 17 at the rear of the shoe 1; the elastic ring 45, as well as the layer of viscoelastic material 23 interposed between the beam 8 and the blade 9, are visible in FIG. 8.
Le patin 1 selon ce second exemple de réalisation permet de réduire la distance qui sépare la semelle 4 du sol S, puisque la poutre 8 et la lame 9 sont situées côte à côte. Le centre de gravité du patin 1 est donc très bas.The shoe 1 according to this second embodiment makes it possible to reduce the distance which separates the sole 4 from the ground S, since the beam 8 and the blade 9 are located side by side. The center of gravity of pad 1 is therefore very low.
Un troisième mode de réalisation est proposé aux figures 9 et 10.A third embodiment is proposed in FIGS. 9 and 10.
Les parties communes aux modes précédents sont encore désignées par les mêmes références et ne sont plus décrites ici.The parts common to the preceding modes are still designated by the same references and are no longer described here.
La différence essentielle provient du fait que la poutre 8 est mobile par rapport à la platine 5 grâce à un système de parallélogramme deformable : des bras 46, 47, 48, 49 articulés selon des axes 50, 51 , 52, 53 permettent un déplacement relatif de la poutre 8, et donc des roues 10, 11 , 12, 13, par rapport à la chaussure 2 du patin 1 , dans un sens d'éloignement ou de rapprochement de la semelle 4.The essential difference comes from the fact that the beam 8 is movable relative to the plate 5 thanks to a deformable parallelogram system: arms 46, 47, 48, 49 articulated along axes 50, 51, 52, 53 allow relative movement of the beam 8, and therefore of the wheels 10, 11, 12, 13, relative to the shoe 2 of the shoe 1, in a direction of separation or approximation of the sole 4.
Le déplacement des roues 10, 1 1 , 12, 13 vers la semelle 4 est limité par contact de la poutre 8 avec la platine 5.The movement of the wheels 10, 11, 12, 13 towards the sole 4 is limited by contact of the beam 8 with the plate 5.
Le déplacement des roues 10, 1 1 , 12, 13 dans le sens d'éloignement de la semelle 4 est quant à lui limité par un moyen de retenue comme celui décrit ci-après ; une extrémité d'un tube 54 est articulée selon une goupille 55 d'axe 56 dans la rainure 7 de la platine 5, comme il est montré à la figure 10. L'autre extrémité du tube 54 comprend un moyen d'arrêt, tel qu'un épaulement 57, destiné à limiter la déformation du parallélogramme réalisé par la platine 5, la poutre 8 et les bras 46, 47 et 48, 49. De ce fait l'éloignement des roues 10, 11 , 12, 13 par rapport à la semelle 4 est limité. A l'état libre, la platine 5 et la poutre 8 sont éloignées au maximum l'une de l'autre par suite de l'action permanente d'un moyen élastique, représenté sous la forme d'un ressort 58, qui agit en permanence dans le sens d'éloignement de la platine 5 et de la poutre 8.The movement of the wheels 10, 11, 12, 13 in the direction of separation from the sole 4 is meanwhile limited by a retaining means such as that described below; one end of a tube 54 is articulated according to a pin 55 of axis 56 in the groove 7 of the plate 5, as shown in FIG. 10. The other end of the tube 54 comprises a stop means, such as that a shoulder 57, intended to limit the deformation of the parallelogram produced by the plate 5, the beam 8 and the arms 46, 47 and 48, 49. Therefore the distance of the wheels 10, 11, 12, 13 relative to sole 4 is limited. In the free state, the plate 5 and the beam 8 are separated at most from each other as a result of the permanent action of an elastic means, represented in the form of a spring 58, which acts permanently in the direction of separation of the plate 5 and the beam 8.
Le fonctionnement du patin 1 selon ce mode de réalisation est similaire aux autres modes, l'avantage étant qu'il fait appel à des techniques de construction plus habituelles.The operation of the shoe 1 according to this embodiment is similar to the other modes, the advantage being that it uses more usual construction techniques.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation ainsi décrits, et comprend tous les équivalents techniques pouvant entrer dans l'étendue des revendications qui vont suivre.Of course, the invention is not limited to the embodiments thus described, and includes all the technical equivalents which may fall within the scope of the claims which will follow.
Notamment, on peut prévoir un nombre de roues différent, des moyens élastiques sous forme de ressorts à spirale à la place de la lame flexible 9, des moyens d'amortissement à fluide au lieu des couches de matériaux viscoélastiques, des guidages de la poutre 8 par cylindres coulissants à la place de contacts dans la rainure 7.In particular, a different number of wheels can be provided, elastic means in the form of spiral springs in place of the flexible leaf 9, fluid damping means instead of layers of viscoelastic materials, guides of the beam 8 by sliding cylinders in place of contacts in groove 7.
On peut également prévoir d'utiliser plusieurs lames flexibles sur chaque patin. We can also plan to use several flexible blades on each shoe.
