Description

La présente invention concerne un dispositif à caractère sportif qui s'applique notamment à la simulation de sport de glisse tel que le ski de fond sur des sols durs tel que notamment des routes.The present invention relates to a sporting device which is particularly applicable to the simulation of sliding sports such as cross-country skiing on hard floors such as in particular roads.

Les dispositifs actuels pour la simulation du ski de fond sur route sont généralement constitués de patins à roulettes sur lesquels ont été adaptés des systèmes de fixation pour chaussures de ski de fond.Current devices for simulating cross-country skiing on the road generally consist of roller skates on which fastening systems for cross-country ski boots have been adapted.

De tels dispositifs ne reproduisent que de façon très imparfaite les sensations du ski de fond notamment dans la simulation de la glisse et du mouvement des jambes du skieur provoquant la glisse. De plus les prises de virage avec de tels dispositifs ne peuvent s'effectuer qu'en utilisant la technique dite du "pas-tournant" qui nécessite que l'utilisateur ait déjà une bonne expérience du ski ce qui nuit à l'utilisation de tels dispositifs par des non-initiés limitant ainsi les perspectives de diffusion de tels dispositifs au niveau du grand public. En outres ils nécessitent une grande dextérité de l'utilisateur lorsqu'il veut ralentir.Such devices reproduce only very imperfectly the sensations of cross-country skiing, in particular in the simulation of the gliding and of the movement of the skier's legs causing the gliding. In addition, cornering with such devices can only be done using the so-called "not-turning" technique which requires that the user already has a good experience of skiing which hinders the use of such devices by non-initiates thus limiting the prospects of dissemination of such devices to the general public. In addition they require great dexterity of the user when he wants to slow down.

De plus, des vibrations, dues au revêtement de la chaussée, sont transmises à la jambe de l'utilisateur par l'intermédiaire des roulettes, il en résulte une utilisation parfois fort désagréable de ces skis sur roulettes qui peut aller jusqu'à ce que l'utilisateur renonce à l'emploi d'un tel dispositif en raison des désagréments causés.In addition, vibrations, due to the coating of the road, are transmitted to the leg of the user via the wheels, this results in a sometimes very unpleasant use of these skis on wheels which can go until the user renounces the use of such a device due to the inconvenience caused.

La présente invention vise à la conception d'un dispositif à caractère sportif destiné notamment à la simulation de sport de glisse sur surface dure telle que des routes, dont l'emploi ne nécessite pas d'expérience particulière préalable, qui assure une bonne sécurité, même à un utilisateur non-initié, et à l'emploi duquel les désagréments dus aux vibrations en raison d'aspérités éventuellement sur la chaussée sont considérablement réduits.The present invention aims at the design of a sporting device intended in particular for simulating sliding sports on hard surfaces such as roads, the use of which does not require any particular prior experience, which ensures good safety, even to an uninitiated user, and to whose use the inconvenience due to vibrations due to roughness possibly on the roadway are considerably reduced.

Selon sa caractéristique principale, la présente invention concerne un dispositif à caractère sportif, caractérisé en ce qu'il comporte une roue dont une surface périphérique externe constitue un premier organe de roulement sur un sol ou sur une surface dure et dont une surface périphérique interne constitue chemin de roulement pour un second organe de roulement d'un support propre à supporter un pied d'un utilisateur, et des moyens de liaison de la roue au corps de l'utilisateur permettant de la maintenir perpendiculairement au sol sans entraver sa rotation.According to its main characteristic, the present invention relates to a sporting device, characterized in that it comprises a wheel of which an external peripheral surface constitutes a first rolling member on a ground or on a hard surface and of which an internal peripheral surface constitutes raceway for a second rolling member of a support capable of supporting a foot of a user, and means for connecting the wheel to the body of the user allowing it to be held perpendicular to the ground without hampering its rotation.

Le support comporte avantageusement une roulette principale constituant, par contact tangentiel avec ladite surface interne de la roue, orgene de roulement du support, ladite roulette principale étant destinée à supporter l'effort radial et l'effort axial exercés par le poids de l'utilisateur sur le support ; et deux contre-roulettes en contact tangentiel avec ladite surface externe de la roue, lesdites contre-roulettes constituant, en coopération avec ledit organe de roulement du support, des moyens de guidage et de maintien dudit support par rapport à la roue, lesdites contre-roulettes étant disposées de part et d'autre de ladite roulette principale dans la direction longitudinale du support et de préférence à équidistance de ladite roulette principale.The support advantageously comprises a main caster constituting, by tangential contact with said internal surface of the wheel, a rolling member of the support, said main caster being intended to support the radial force and the axial force exerted by the weight of the user. on the support; and two counter rollers in tangential contact with said outer surface of the wheel, said counter rollers constituting, in cooperation with said rolling member of the support, means for guiding and holding said support relative to the wheel, said counter rollers rollers being arranged on either side of said main caster in the longitudinal direction of the support and preferably equidistant from said main caster.

Le roulement sur le sol d'effectue désormais par l'intermédiaire d'une roue qui présente un diamètre sensi­blement plus grand que celui des roulettes des patins connus et qui se trouve intercalée entre le sol et une roulette principale servant d'organe de roulement au support. Le diamètre de la roue est tel que le roulement du support sur son chemin interne s'effectue sans fatigue et que le centre de gravité du support est maintenu à une faible distance du sol ce qui améliore la stabilité du dispositif.The rolling on the ground now takes place by means of a wheel which has a diameter substantially larger than that of the rollers of the known pads and which is interposed between the ground and a main caster serving as a rolling member for the support. The diameter of the wheel is such that the rolling of the support on its internal path is carried out without fatigue and that the center of gravity of the support is maintained at a short distance from the ground which improves the stability of the device.

Lorsque le support est horizontal, le point de tangence de la roulette principale sur la surface interne de la roue est aligné avec le centre de la roue et le point de tangence de la roue sur le sol. Lors de l'utilisation, un décalage du centre de gravité de l'utilisateur par rapport à cet alignement se traduit, selon le sens du décalage, par un report du poids sur la pointe du pied et donc sur l'avant du support ou sur le talon et donc sur l'arrière du support entraînant ainsi une inclinaison du patin vers l'avant ou respectivement vers l'arrière et un décalage du point de tangence de la roulette principale par rapport à l'alignement du centre de la roue et du point de tangence de la roue sur le sol. Le mouvement cycloïdal ainsi créé permet de simuler de manière très réaliste les sensations de glisse qu'un utilisateur peut avoir sur des skis. Le point de tangence entre la roulette principale et le chemin de roulement intérieur de la roue constituant le point de basculement du patin. La prise de virage peut désormais être effectuée sans avoir à décoller un dispositif du sol grâce au basculement du patin.When the support is horizontal, the point of tangency of the main caster on the internal surface of the wheel is aligned with the center of the wheel and the point of tangency of the wheel on the ground. In use, a shift in the center of gravity of the user relative to this alignment results, depending on the direction of the shift, by a weight transfer on the tiptoe and therefore on the front of the support or on the heel and therefore on the rear of the support thus causing the skate to tilt forwards or backwards respectively and a shift in the point of tangency of the main caster relative to the alignment of the center of the wheel and the point of tangency of the wheel on the ground. The cycloidal movement thus created makes it possible to simulate in a very realistic way the gliding sensations that a user can have on skis. The point of tangency between the main caster and the inner raceway of the wheel constituting the point of tilting of the shoe. Turning can now be carried out without having to take off a device from the ground thanks to the tilting of the skate.

Les deux contre-roulettes qui sont disposées chacune à une extrémité du support permettent d'assurer un guidage et un maintien du patin par rapport à la roue, permettant ainsi que le mouvement pendulaire par inclinaison du patin alternativement vers l'avant et vers l'arrière soit réalisé en toute sécurité.The two counter-rollers, which are each arranged at one end of the support, make it possible to guide and hold the shoe in relation to the wheel, thereby enabling the pendulum movement by tilting the shoe alternately forward and inward. rear be carried out safely.

Le support comporte avantageusement dans une partie inférieure avant, un tampon propre à prendre appui sur le sol lors d'une inclinaison du support par rapport à l'horizontale vers l'avant ; et dans une partie inférieure arrière, ledit support comporte dans une partie inférieure arrière une roulette stabilisatrice propre à prendre appui sur le sol lors d'une inclinaison du support par rapport à l'horizontale vers l'arrière.The support advantageously comprises in a lower front part, a pad capable of bearing on the ground during an inclination of the support relative to the horizontal towards the front; and in a rear lower part, said support comprises in a rear lower part a stabilizing wheel capable of bearing on the ground during an inclination of the support relative to the horizontal towards the rear.

Le tampon et cette roulette stabilisatrice permettent d'améliorer la simulation d'un sport de glisse tel le ski de fond. Le tampon permet la propulsion du dispositif lors d'un basculement avant ou d'une inclinaison vers l'avant du support, et la roulette stabilisatrice assure l'équilibre du dispositif lors d'un basculement ou d'une inclinaison arrière du support.The buffer and this stabilizing wheel improve the simulation of a sliding sport such as cross-country skiing. The buffer allows the device to be propelled during a front tilting or tilting towards the front of the support, and the stabilizing wheel ensures the balance of the device during a tilting or a rear tilting of the support.

Le support comporte avantageusement dans une partie supérieure avant des moyens de fixation d'une pointe d'une chaussure, lesdits moyens de fixation étant articulés de manière à permettre au talon de la chaussure d'être décollé du support, ledit support comportant, de préférence dans une partie supérieure arrière, une talonnette destinée au talon de la chaussure.The support advantageously comprises in an upper front part means for fixing a point of a shoe, said fixing means being articulated so as to allow the heel of the shoe to be detached from the support, said support preferably comprising in a rear upper part, a heel for the heel of the shoe.

De tels moyens de fixation peuvent par exemple consister en des moyens classiques de fixation d'une chaussure de ski de fond et permettent ainsi à l'utilisateur du dispositif de retrouver les sensations de glisse du ski de fond en effectuant les mêmes mouvements de propulsion qu'il effectuerait sur des skis. Une talonnette destinée au talon de la chaussure est de préférence prévue dans la partie supérieure arrière du support.Such binding means may for example consist of conventional means for attaching a cross-country ski boot and thus allow the user of the device to recover the sliding sensations of the cross-country ski by performing the same propulsion movements as 'he would perform on skis. A heel for the heel of the shoe is preferably provided in the upper rear part of the support.

Le support comporte avantageusement deux parois latérales encadrant la roue et comportant des moyens de fixation des axes desdites roulettes et contre-roulettes, lesdites parois étant reliées dans leur partie supérieure par une plaque destinée à supporter le pied de l'utilisateur.The support advantageously comprises two side walls framing the wheel and comprising means for fixing the axes of said rollers and counter-rollers, said walls being connected in their upper part by a plate intended to support the foot of the user.

La forme de chappe du support qui est guidé sur la roue au moyen de la roulette principale placée approximati­vement au centre du support et des deux contre-roulettes positionnées de préférence aux extrémités de celui-ci, permet que le centre de gravité du support soit situé le plus près de sol possible sans entraver pour autant le fonctionnement du dispositif.The shape of the support chappe which is guided on the wheel by means of the main caster placed approximately in the center of the support and of the two counter-rollers positioned preferably at the ends thereof, allows the center of gravity of the support to be located as close to the ground as possible without hampering the operation of the device.

Le dispositif selon l'invention comporte avanta­ geusement des moyens d'attache souples au corps de l'utilisateur et de préférence à sa jambe, d'un organe rigide de guidage latéral de la roue dans sa partie diamétralement opposée au support ; lesdits moyens d'attache pouvant consister en une sangle élastiques réglable, propre à être solidaire de l'organe rigide et à entourer une jambe de l'utilisateur, ou en une ceinture ou un harnais porté par l'utilisateur et, au moins une bretelle élastique réglable, propre à relier ledit organe à ladite ceinture ou audit harnais.The device according to the invention comprises avanta suitably flexible attachment means to the body of the user and preferably to his leg, of a rigid member for lateral guiding of the wheel in its part diametrically opposite the support; said attachment means which may consist of an adjustable elastic strap capable of being secured to the rigid member and surrounding a user's leg, or of a belt or a harness worn by the user and, at least one shoulder strap adjustable elastic, suitable for connecting said member to said belt or to said harness.

La roue est ainsi liée dans sa partie opposée au sol au corps de l'utilisateur, elle peut être ainsi maintenue approximativement perpendiculairement au sol de manière à assurer une bonne stabilité au dispositif.The wheel is thus linked in its part opposite the ground to the body of the user, it can thus be held approximately perpendicular to the ground so as to ensure good stability to the device.

Les figures 1, 2 et 3 représentent un dispositif selon l'invention dans trois positions de basculement d'un support 1 permettant de mieux comprendre le fonctionnement du dispositif lors de son utilisation.Figures 1, 2 and 3 show a device according to the invention in three tilting positions of a support 1 allowing a better understanding of the operation of the device during its use.

Celui-ci comporte une roue 2 qui constitue organe de roulement sur un sol ou sur une surface dure telle qu'une route, et dont la partie opposée au sol est maintenue au corps d'un utilisateur par des moyens de liaison 10 qui seront explicités par la suite.This comprises a wheel 2 which constitutes a rolling member on a ground or on a hard surface such as a road, and the part opposite to the ground is held in the body of a user by connecting means 10 which will be explained thereafter.

Le support ou patin 1 est placé à cheval sur la roue 2, il forme une chappe qui est guidée sur la roue grâce à une roulette principale 3 placée au centre et deux contre-roulettes 5 et 7 positionnées aux extrémités. La roulette principale 3 se déplace sur la surface périphérique interne de la roue 2 qui constitue chemin de roulement pour cette roulette principale 3, elle reçoit la charge exercée par l'utilisateur lors de son évolution. Les deux contre-roulettes 5 et 7 évoluent sur le chemin de roulement extérieur de la roue 2 et assurent le guidage et le maintien du support 1.The support or pad 1 is placed astride the wheel 2, it forms a chappe which is guided on the wheel by means of a main caster 3 placed in the center and two counter-casters 5 and 7 positioned at the ends. The main caster 3 moves on the internal peripheral surface of the wheel 2 which constitutes the raceway for this main caster 3, it receives the load exerted by the user during its evolution. The two counter-rollers 5 and 7 move on the outer raceway of the wheel 2 and guide and maintain the support 1.

Le point de tangence entre la roulette principale 3 et le chemin de roulement intérieur de la roue 2 constitue le point de basculement du support 1.The point of tangency between the main caster 3 and the inner raceway of the wheel 2 constitutes the tilting point of the support 1.

Un tampon en caoutchouc 4 disposé dans la partie inférieure avant du support 1 permet la propulsion du dispositif lors d'un basculement avant du support 1 selon la figure 1. Une roulette stabilisatrice 6, disposée dans la partie inférieure arrière du support 1, facilite la recherche d'équilibre lors d'un basculement arrière du support 1 selon la figure 3.A rubber pad 4 placed in the lower front part of the support 1 allows the device to be propelled during a front tilting of the support 1 according to FIG. 1. A stabilizing wheel 6, placed in the rear lower part of the support 1, facilitates the search for balance during a rear tilting of the support 1 according to FIG. 3.

Le support 1 est destiné à supporter le pied d'un utilisateur, de préférence par l'intermédiaire d'une chaussure 12 dont l'avant est solidaire du support 1 comme on le verra par la suite.The support 1 is intended to support the foot of a user, preferably by means of a shoe 12, the front of which is integral with the support 1 as will be seen later.

L'utilisation du dispositif selon l'invention s'effectue de la manière suivant. L'utilisateur dispose de deux dispositifs, un pour chaque pied. Il pose un pied sur chaque support 1, la pointe de la chaussure 12 dirigée vers l'avant du support.The use of the device according to the invention is carried out in the following manner. The user has two devices, one for each leg. He places one foot on each support 1, the tip of the shoe 12 directed towards the front of the support.

La roue 2 de chaque dispositif est liée dans sa partie opposée au sol, au corps de l'utilisateur, respec­tivement à gauche et à droite de ce dernier de manière à la maintenir perpendiculairement au sol sans entraver sa rotation ni entraver le rapprochement des jambes de l'utilisateur.The wheel 2 of each device is linked in its part opposite the ground, to the body of the user, respectively to the left and to the right of the latter so as to keep it perpendicular to the ground without hampering its rotation or hindering the bringing together of the legs of the user.

La poussée du dispositif s'effectue de manière similaire à celle d'un ski de fond sur neige, en avançant successivement le dispositif gauche, respectivement droit, puis le dispositif droit, respectivement gauche, et ainsi de suite. La figure 1 représente la position du support ou patin 1 lorsque le dispositif gauche, respectivement droit est décalé vers l'arrière par rapport à l'axe du corps de l'utilisateur, l'appui du pied gauche, respectivement droit s'effectuant par la pointe de la chaussure 12, permettant ainsi, par appui sur le sol du tampon 4, la propulsion du dispositif droit, respectivement gauche, qui passe succes­sivement par les positions représentées à la figure 2 où il est aligné part rapport à l'axe du corps de l'utilisateur, et à la figure 3 où il se trouve décalé vers l'avant par rapport à cet axe. Une fois le dispositif droit, respec­tivement gauche, dans la position représentée à la figure 3, l'utilisateur ramène le dispositif gauche, respec­tivement droit, dans la position représentée à la figure 2, puis le propulse vers l'avant dans la positon tel que représenté à la figure 3. Pendant ce temps le dispositif droit, respectivement gauche, reprend successivement les positions représentées aux figures 1 et 2.The device is pushed similarly to that of a cross-country ski on snow, by successively advancing the left device, respectively right, then the right device, respectively left, and so on. FIG. 1 represents the position of the support or pad 1 when the left, respectively right device is offset rearward relative to the axis of the user's body, the support of the left, respectively right foot being effected by the tip of the shoe 12, thus allowing, by pressing on the ground of the pad 4, the propulsion of the right device, respectively left, which passes successively through the positions shown in Figure 2 where it is aligned share relative to the axis of the user body, and in Figure 3 where it is offset forward relative to this axis. Once the right device, respectively left, in the position shown in Figure 3, the user brings the left device, respectively right, in the position shown in Figure 2, then propels it forward into the position as represented in FIG. 3. During this time, the right device, respectively left, successively takes up the positions represented in FIGS. 1 and 2.

Dans une position de roulement libre, les deux dispositifs gauche et droit se trouvent alignés par rapport à l'axe du corps de l'utilisateur dans une position tel que représenté à la figure 2. Dans cette position, l'appui du corps de l'utilisateur s'effectue sur toute la surface inférieure de la chaussure 12 de manière régulière sur le support 1.In a free rolling position, the two left and right devices are aligned relative to the axis of the body of the user in a position as shown in Figure 2. In this position, the support of the body of the The user performs over the entire lower surface of the shoe 12 regularly on the support 1.

La figure 4 représente un premier mode de réalisation des moyens de liaison de la roue 2 au corps de l'utilisateur. Un étrier baladeur 10, constituant organe rigide de guidage est attaché à la jambe 21 de l'utilisateur à l'aide d'une sangle élastique souple 19, reçue dans des passages 11 (figure 6) prévus dans une paroi latérale ou joue de l'étrier 10 et assure le contrôle de perpendicularité du dispositif par rapport au sol. L'étrier est de préférence attaché en-dessous du genou de l'utilisateur afin de ne pas gêner les mouvements de flexion de celui-ci. La structure et le fonctionnement de l'étrier 10 seront décrits à l'appui des figures 10, 11 et 12.FIG. 4 represents a first embodiment of the means for connecting the wheel 2 to the body of the user. A sliding stirrup 10, constituting a rigid guide member, is attached to the user's leg 21 using a flexible elastic strap 19, received in passages 11 (FIG. 6) provided in a side wall or cheek of the 'caliper 10 and ensures the perpendicularity of the device relative to the ground. The stirrup is preferably attached below the knee of the user so as not to hinder the bending movements of the latter. The structure and operation of the stirrup 10 will be described in support of FIGS. 10, 11 and 12.

La figure 5 représente en vue de face le dispositif représenté à la figure 4, il s'agit d'un dispositif lié à la jambe droite de l'utilisateur. Cette figure fait apparaître un mode de réalisation de moyens de freinage du dispositif selon l'invention ; ceux-ci sont constitués d'un sabot 17 qui est propre à frotter sur la roue 2 avec prise d'appui sur l'étrier 10. Le sabot pourra être sollicité directement à la main ou par un système de commande à distance, par exemple par câble 20, à partir d'un bâton 18. Le bâton ayant la même utilité qu'en ski de fond, mais comportant, de préférence à son extrémité inférieure, une sphère de caoutchouc 37.5 shows in front view the device shown in Figure 4, it is a device linked to the right leg of the user. This figure shows an embodiment of braking means of the device according to the invention; these consist of a shoe 17 which is suitable for rubbing on the wheel 2 with support on the caliper 10. The shoe can be operated directly by hand or by a remote control system, for example by cable 20, from a stick 18. The stick having the same utility as cross-country skiing, but comprising, preferably at its end bottom, a rubber sphere 37.

La figure 6 représente une vue agrandie d'un dispositif permettant de mieux faire apparaître ses détails. Cette figure a été représentée partiellement par souci de clarté. Les éléments communs aux figures précédentes y ont été désignés par les mêmes références.FIG. 6 represents an enlarged view of a device making it possible to better reveal its details. This figure has been partially represented for the sake of clarity. The elements common to the previous figures have been designated by the same references.

Le profil du support 1 présente une forme (figure 7) permettant de créer un dégagement pour la fixation du tampon 4 et pour faciliter les trois phases de basculement du support. Le support présente, en coupe transversale, une forme de chappe (figure 8) constituée de deux parois latérales 22 et 23 reliées dans une partie supérieure par une plaque support 24 destinée à supporter le pied de l'utilisateur. Les parois 22 et 23 présentent des ouvertures 32 aux endroits des passages des axes des roulettes 3 et 6 etm des contre-roulettes 5 et 7 afin d'en permettre la fixation.The profile of the support 1 has a shape (Figure 7) to create a clearance for the attachment of the buffer 4 and to facilitate the three phases of tilting of the support. The support has, in cross section, a shape of a screed (Figure 8) consisting of two side walls 22 and 23 connected in an upper part by a support plate 24 intended to support the foot of the user. The walls 22 and 23 have openings 32 at the locations of the passages of the axes of the rollers 3 and 6 and of the counter-rollers 5 and 7 in order to allow the fixing thereof.

La plaque support 24 ne s'étend pas jusqu'aux extrémités des parois latérales 22 et 23 de manière à permettre le passage de la roue 2. Deux balais 8 en matière synthétique souple épousant le profil de la roue 2, assurent le nettoyage des chemins de roulement, un premier balai 8, placé dans la partie antérieure du support 1, est destiné à nettoyer le chemin de roulement interne de la roue, et une second balai 8, placé dans la partie antérieure du support 1, est destiné à nettoyer le chemin de roulement externe de la roue.The support plate 24 does not extend to the ends of the side walls 22 and 23 so as to allow the passage of the wheel 2. Two brushes 8 made of flexible synthetic material conforming to the profile of the wheel 2, ensure the cleaning of the paths of rolling, a first brush 8, placed in the front part of the support 1, is intended to clean the internal raceway of the wheel, and a second brush 8, placed in the front part of the support 1, is intended to clean the external raceway of the wheel.

La plaque support 24 du support 1 comporte des moyens 14 de fixation articulée de la pointe de la chaussure 12. Elle comporte également une talonnette 13 destinée au talon de la chaussure.The support plate 24 of the support 1 comprises means 14 for articulated fixing of the toe of the shoe 12. It also includes a heel 13 intended for the heel of the shoe.

Dans la partie supérieure de la roue 2, l'étrier 10 encadre cette dernière au moyen de deux parois latérales qui sont reliées par trois roulettes de guidage 9 dont deux ont pour chemin de roulement la surface interne de la roue 2 et dont une a pour chemin de roulement la surface externe de cette même roue. L'étrier 10 se compose de deux plaques triangulaires parallèles (figure 10), les roulettes 9 (figure 11) permettant de maintenir l'espacement nécessaire au passage de la roue dans l'étrier, sans entraver le roulement. La paroi latérale de l'étrier 10, en regard de la jambe de l'utilisateur, présente deux lumières 11 qui sont destinées au passage de la sangle 19 prévue pour l'attache de l'étrier à la jambe de l'utilisateur.In the upper part of wheel 2, the caliper 10 frames the latter by means of two side walls which are connected by three guide rollers 9, two of which have the internal surface of the wheel 2 as a raceway and one of which has the external surface of the same wheel as the raceway. The caliper 10 consists of two parallel triangular plates (Figure 10), the rollers 9 (Figure 11) to maintain the spacing necessary for the passage of the wheel in the caliper, without hampering the bearing. The side wall of the stirrup 10, facing the leg of the user, has two slots 11 which are intended for the passage of the strap 19 provided for attaching the stirrup to the leg of the user.

Un sabot 17, articulé sur l'étrier 10 et propre à venir frotter sur la surface périphérique externe de la roue 2, constitue les moyens de freinage du dispositif.A shoe 17, articulated on the caliper 10 and suitable for rubbing on the external peripheral surface of the wheel 2, constitutes the braking means of the device.

La roue 2, comme le montre les figures 9 et 12, peut être constituée d'une jante 33 sur la surface périphérique externe de laquelle est collée une première ceinture caoutchoutée 16, et sur la surface périphérique interne de laquelle est collée une seconde ceinture caoutchoutée 15. Ces deux ceintures caoutchoutées 15 et 16 permettent de limiter les vibrations du dispositif dues aux aspérités de la chaussée tout en servant d'amortisseur et en rendant les roulements silencieux.The wheel 2, as shown in FIGS. 9 and 12, can consist of a rim 33 on the external peripheral surface of which is glued a first rubberized belt 16, and on the internal peripheral surface of which is glued a second rubberized belt 15. These two rubber belts 15 and 16 make it possible to limit the vibrations of the device due to the roughness of the road while serving as a shock absorber and making the bearings silent.

Comme le montre les figures 9 et 12 les roulettes 9 de l'étrier 10 ainsi que la roulette principale 3 ont un diamètre au centre plus réduit qu'à l'extérieur de manière à assurer en même temps que le roulement, un guidage latéral de la roue. Les contre-roulettes 5 et 6 peuvent également être du même type.As shown in FIGS. 9 and 12, the rollers 9 of the caliper 10 as well as the main roller 3 have a smaller diameter in the center than on the outside so as to ensure, at the same time as the bearing, lateral guidance of wheel. The counter rollers 5 and 6 can also be of the same type.

Les figures 13 et 14 représentent un second mode de réalisation des moyens de liaison de la roue 2 au corps de l'utilisateur. Un organe rigide de guidage est constitué d'une fourche 25 dont un manche 36 est attaché à la jambe 21 de l'utilisateur au moyen d'une sangle élastique souple 26 identique à la sangle 19 précédemment décrite, et dont deux branches parallèles 34 et 35 encadrent la roue 2 de manière à réaliser un guidage latéral.Figures 13 and 14 show a second embodiment of the means for connecting the wheel 2 to the body of the user. A rigid guide member consists of a fork 25, a handle 36 of which is attached to the user's leg 21 by means of a flexible elastic strap 26 identical to the strap 19 previously described, and of which two parallel branches 34 and 35 surround the wheel 2 so as to provide lateral guidance.

Le support publicitaire représenté à la figure 15 est constitué de deux panneaux 29 et 30 en forme de demi-­lune qui masquent l'espace interne de la roue 2, en laissant visible la jambe 21 de l'utilisateur. Ces deux panneaux sont fixés à chacune de leurs extrémités à l'étrier 10 et au support 1 ; ils peuvent comporter une armature rigide du type d'un cerclage métallique ou être constituer en un tissu propre à assurer par lui-même sa rigidité. Des lattes 31 du type de celles utilisées dans les voiles de navires peuvent être employées pour assurer une rigidité nécessaire au panneau publicitaire.The advertising medium shown in FIG. 15 is made up of two half-moon shaped panels 29 and 30 which hide the internal space of the wheel 2, leaving the user's leg 21 visible. These two panels are fixed at each of their ends to the bracket 10 and to the support 1; they may include a rigid frame of the type of a metal banding or be made of a fabric suitable for ensuring by itself its rigidity. Slats 31 of the type used in ship sails can be used to provide the necessary rigidity for the advertising panel.

La figure 16 représente une variante des moyens d'attache des moyens de liaison de la roue 2 au corps de l'utilisateur. Ceux-ci sont constitués d'une bretelle élastique souple 27 dont une des extrémités est fixée à l'étrier 10 et dont l'autre extrémité est destinée à être fixée à un harnais ou à une ceinture portée par l'utilisateur. Afin d'assurer la perpendicularité de la roue 2 par rapport au sol, une ceinture élastique souple 28 entoure la cuisse de l'utilisateur en maintenant la bretelle 27 plaquée contre celle-ci.FIG. 16 represents a variant of the means of attachment of the means for connecting the wheel 2 to the body of the user. These consist of a flexible elastic strap 27, one end of which is fixed to the stirrup 10 and the other end of which is intended to be fixed to a harness or to a belt worn by the user. In order to ensure the perpendicularity of the wheel 2 with respect to the ground, a flexible elastic belt 28 surrounds the thigh of the user while keeping the strap 27 pressed against the latter.

Selon un mode de réalisation particulier du dispositif selon l'invention, le support 1, la jante 33, la roulette principale 3, les contre-roulettes 5 et 7, la roulette stabilisatrice 6 et les roulettes de guidage 9 sont en alliage léger tel que le duralumin ou en matière composite. Le tampon 4 est en caoutchouc et est rapporté par vis sur la partie inférieure avant du patin. La roulette principale 6 ainsi que les contre-roulettes 5 et 7 sont dimensionnées de manière à ce que le plan inférieur du support 1 soit à une distance d'environ 25 mm du sol.According to a particular embodiment of the device according to the invention, the support 1, the rim 33, the main caster 3, the counter-rollers 5 and 7, the stabilizing caster 6 and the guide rollers 9 are made of light alloy such as duralumin or composite material. The pad 4 is made of rubber and is attached by screws to the lower front part of the pad. The main caster 6 as well as the counter-casters 5 and 7 are dimensioned so that the lower plane of the support 1 is at a distance of approximately 25 mm from the ground.

La ceinture caoutchoutée 16 peut être remplacée par un pneu gonflé à l'air, de manière à permettre l'utilisation de jantes classiques.The rubberized belt 16 can be replaced by an air-inflated tire, so as to allow the use of conventional rims.
