Description

PATIN A ROUES A FREINAGE AVEC ROUE ESCAMOTABLE BRAKE WHEEL SKATE WITH RETRACTABLE WHEEL
La présente invention concerne le domaine des patins à roues ou roulettes, alignées ou non, c'est-à-dire aussi bien les patins dits à roulettes que les patins dits à roues en ligne, ou autres patins munis de roues.The present invention relates to the field of roller skates or rollers, aligned or not, that is to say both the so-called roller skates that the so-called inline skates, or other skates provided with wheels.
Les systèmes de freinages connus à ce jour pour de tels patins sont de plusieurs types :The braking systems known to date for such skates are of several types:
1 - Ceux qui agissent sur une ou plusieurs roues, soit par frottement d'un ferodo sur un tambour ou un disque, soit directement sur la bande de roulement d'une ou plusieurs roues.1 - Those which act on one or more wheels, either by friction of a ferodo on a drum or a disc, or directly on the tread of one or more wheels.
L'inconvénient de ce type de freinage est que l'on arrive rapidement au blocage de la roue d'où usure de celle-ci et formation de "plats".The disadvantage of this type of braking is that one quickly arrives at the blocking of the wheel from where wear of this one and formation of "flat".
2- Ceux qui agissent par l'intermédiaire d'un élément de freinage fixé de manière immobile sur le châssis. Ces systèmes de freinage sont efficaces pour les patineurs confirmés mais difficiles à mettre en oeuvre pour les débutants car ils donnent une position d'instabilité. Par ailleurs, ils peuvent difficilement être utilisés pour ralentir en descente.2- Those who act through a braking element fixed immobile on the chassis. These braking systems are effective for confirmed skaters but difficult to implement for beginners because they give a position of instability. In addition, they can hardly be used to slow downhill.
3- Ceux qui agissent par l'intermédiaire d'un patin de freinage fixé de manière mobile sur le châssis qui peut être abaissé grâce au mouvement du collier de la chaussure auquel il est relié. Ces systèmes de freinage sont progressifs et donnent de la stabilité au patineur car les roues restent en contact avec le sol, mais ils perdent en efficacité.3- Those who act by means of a brake shoe fixed in a mobile way on the chassis which can be lowered thanks to the movement of the collar of the shoe to which it is connected. These braking systems are progressive and give stability to the skater because the wheels remain in contact with the ground, but they lose efficiency.
4- Un autre système de freinage connu a pour effet, lorsqu'il est en action, de faire passer un moyen de freinage mobile, d'une position de repos au-dessus du plan inférieur des roues, à une position de freinage en-dessous de ce plan.4- Another known braking system has the effect, when in action, of moving mobile braking means from a rest position above the lower plane of the wheels to a braking position below this plan.
Ce système a pour inconvénient un manque de progressivité dans l'action de freinage et ne peut pas fournir d'effet de ralentissement lors d'une descente.This system has the disadvantage of a lack of progressiveness in the braking action and cannot provide a deceleration effect during a descent.
Un autre inconvénient est qu'il faut soulever le pied pour passer d'une position dite de freinage à une position dite de repos.Another disadvantage is that it is necessary to lift the foot to pass from a so-called braking position to a so-called rest position.
Le but de l'invention est de remédier à ces inconvénients et notamment d'offrir un patin et ensemble de freinage pour patin qui procure une certaine stabilité ou équilibre à un utilisateur débutant tout en étant progressif et 'puissant' suivant les besoins de l'utilisateur. Le système doit pouvoir également convenir à un patineur confirmé grâce à des réglages s'adaptant à sa pratique.The object of the invention is to remedy these drawbacks and in particular to offer a skate and skate brake assembly which provides a certain stability or balance to a beginner user while being progressive and 'powerful' according to the needs of the user. user. The system must also be able to suit a confirmed skater thanks to adjustments adapted to his practice.
Ce but est atteint dans le patin selon l'invention, qui est du type comportant un châssis apte à être rendu solidaire d'une chaussure et sur lequel sont montées au moins deux roues disposées en ligne, ainsi qu'un patin de freinage disposé à l'arrière des roues, par le fait que des moyens d'escamotage à distance de la surface d'appui sont associés à au moins la roue arrière la plus proche du frein, de manière à escamoter la dite roue lors de la venue du frein en contact avec le sol. De ce fait les roues disposées à l'avant de la ou les roues escamotables restent en contact avec le sol et définissent avec le frein une surface d'appui augmentée lors du freinage.This object is achieved in the skate according to the invention, which is of the type comprising a chassis capable of being made integral with a shoe and on which are mounted at least two wheels arranged in line, as well as a brake shoe arranged at the rear of the wheels, by the fact that retracting means remote from the bearing surface are associated with at least the rear wheel closest to the brake, so as to retract said wheel when the brake comes into contact with the ground. As a result, the wheels disposed at the front of the retractable wheel or wheels remain in contact with the ground and define with the brake an increased bearing surface during braking.
Il en résulte une plus grande stabilité du patin pendant la phase de freinage, ce qui est particulièrement important pour un utilisateur débutant. Bien entendu un tel système convient également à un patineur confirmé.This results in greater stability of the pad during the braking phase, which is particularly important for a beginner user. Of course such a system is also suitable for an experienced skater.
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 illustrant, à titre d'exemples non limitatifs, deux modes de réalisation préférés et dans lequel :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 illustrating, by way of nonlimiting examples, two modes preferred embodiments and in which:
- la figure 1 est une vue en perspective d'un patin à roues en ligne selon l'invention en position de freinage, le patin proprement dit étant représenté en traits fins,FIG. 1 is a perspective view of an in-line roller skate according to the invention in the braking position, the pad itself being shown in thin lines,
- la figure 2 est une vue de côté du patin de la figure 1 en position de glisse normale du patin,FIG. 2 is a side view of the skate of FIG. 1 in the normal sliding position of the skate,
- les figures 3 à 5 sont des vues similaires à la figure 2 montrant l'entrée en action progressive du patin de freinage et l'escamotage correspondant de la roue la plus arrière,FIGS. 3 to 5 are views similar to FIG. 2 showing the entry into progressive action of the brake shoe and the corresponding retraction of the rearmost wheel,
- la figure 6 est un vue de détail des moyens d'escamotage de la roue arrière en position de repos.- Figure 6 is a detail view of the retracting means of the rear wheel in the rest position.
- la figure 7 est une vue similaire à la figure 2 de l'arrière d'un patin utilisant un système d'escamotage amélioré,FIG. 7 is a view similar to FIG. 2 of the rear of a skate using an improved retraction system,
- la figure 8 est une vue similaire à la figure 7 en position de freinage.- Figure 8 is a view similar to Figure 7 in the braking position.
- la figure 9 est une vue de détail du système d'escamotage de la roue arrière, Ainsi que le montrent particulièrement les figures 1 à 4, le patin selon l'invention est constitué essentiellement d'une partie chaussure, formée en l'occurrence d'une partie basse 2 et d'un collier 4, destiné à entourer et soutenir la cheville de l'utilisateur et articulé sur ladite partie basse, et d'une partie châssis 6 portant les roues 3, 15, 16, 17.- Figure 9 is a detailed view of the retraction system of the rear wheel, As shown particularly in Figures 1 to 4, the shoe according to the invention consists essentially of a shoe part, formed in this case a lower part 2 and a collar 4, intended to surround and support the ankle of the user and articulated on said lower part, and a chassis part 6 carrying the wheels 3, 15, 16, 17.
Ainsi que cela sera expliqué plus loin et comme le montre particulièrement la figure 1 , la roue 3 la plus arrière est montée articulée par rapport au châssis 6 par l'intermédiaire d'une fourche 5. Cette articulation permet un déplacement en direction verticale de ladite roue 3 par rapport au châssis.As will be explained below and as shown in particular in Figure 1, the rearmost wheel 3 is mounted articulated with respect to the chassis 6 by means of a fork 5. This articulation allows movement in the vertical direction of said wheel 3 relative to the chassis.
On notera également que l'articulation de collier 4 sur la partie basse 2 de la chaussure est prévue de façon à permettre au moins un pivotement ou basculement vers l'arrière dudit collier 4 par rapport à ladite partie basse 2. Un tel mouvement de pivotement peut bien entendu être obtenu par d'autres moyens connus en soi et, par exemple, l'ensemble partie basse 2, collier 4 de la chaussure pourraient notamment être conçus de façon au moins partiellement monobloc, le collier 4 étant solidaire de ladite partie basse mais pouvant néanmoins pivoter par rapport à celle-ci, de la façon décrite, par des découpes appropriées prévues au niveau de la zone de jonction de ces deux parties.It will also be noted that the collar articulation 4 on the lower part 2 of the shoe is provided so as to allow at least one pivoting or tilting towards the rear of said collar 4 relative to said lower part 2. Such a pivoting movement can of course be obtained by other means known per se and, for example, the lower part 2, collar 4 of the shoe could in particular be designed at least partially in one piece, the collar 4 being integral with said lower part but which can nevertheless pivot relative to the latter, in the manner described, by suitable cutouts provided at the junction zone of these two parts.
Le patin est par ailleurs muni à l'arrière d'un système de freinage 10 associé à un patin de freinage 13, monté sur une extension 18 du châssis 6. Le patin de freinage 13 est donc solidaire et fixe par rapport au châssis 6.The pad is also provided at the rear with a braking system 10 associated with a braking pad 13, mounted on an extension 18 of the chassis 6. The braking pad 13 is therefore secured and fixed relative to the chassis 6.
Le système de freinage 10 est en fait constitué par des moyens de relevage ou d'escamotage de la roue 3 située juste en avant du patin de freinage 13, et par conséquent la roue arrière la plus proche dudit patin.The braking system 10 is in fact constituted by means for lifting or retracting the wheel 3 situated just in front of the brake shoe 13, and consequently the rear wheel closest to said shoe.
Ces moyens d'escamotage sont plus particulièrement visibles sur la figure 1 et ils sont constitués :These retraction means are more particularly visible in FIG. 1 and they consist of:
- de la fourche 5 dont une extrémité 5a est fixée et articulée sur le châssis 6 autour de l'axe x1 et dont l'autre extrémité, constituée de 2 branches 5b, porte la roue arrière 3 montée rotative autour de l'axe x2,- the fork 5, one end of which 5a is fixed and articulated on the chassis 6 around the axis x1 and the other end of which, consisting of 2 branches 5b, carries the rear wheel 3 rotatably mounted around the axis x2,
- d'un palonnier 7, également en forme de fourche, qui est articulé par les 2 branches 7a d'une première extrémité sur la fourche 6, au niveau de l'axe x2, sur lequel est également montée la roue 3, et qui est articulé à son autre extrémité 7b à une biellette 8, par un axe x4,- a lifting beam 7, also in the form of a fork, which is articulated by the 2 branches 7a of a first end on the fork 6, at the level of the axis x2, on which the wheel 3 is also mounted, and which is articulated at its other end 7b to a link 8, by an axis x4,
- de la biellette 8, qui, par sa zone centrale, est fixée et articulée sur le châssis- the link 8, which, by its central zone, is fixed and articulated on the chassis
6 ou un élément du châssis, au niveau de l'axe x3, qui par ailleurs, est articulée en x4, par une première extrémité 8a, au palonnier 7 et qui est reliée de façon pivotante par son autre extrémité 8b à un étrier 9, par l'intermédiaire d'un axe x5,6 or an element of the frame, at the level of the axis x3, which moreover is articulated at x4, by a first end 8a, to the lifting beam 7 and which is pivotally connected by its other end 8b to a stirrup 9, via an x5 axis,
- de l'étrier 9 articulé avec la biellette 8 au niveau de l'axe x5,- the stirrup 9 articulated with the link 8 at the axis x5,
- d'une tige de commande 11 fixée de manière réglable en longueur sur l'étrier 9, par une première extrémité 11 a, et montée coulissante par son autre extrémité 11 b à l'intérieur de l'évidement 12a d'un fourreau 12, lui-même fixé et articulé sur le collier 4 au niveau de l'axe x6.- a control rod 11 fixed in an adjustable manner in length to the stirrup 9, by a first end 11 a, and slidingly mounted by its other end 11 b inside the recess 12a of a sheath 12 , itself fixed and articulated on the collar 4 at the axis x6.
Le déplacement de la tige de commande 11 à l'intérieur du fourreau 12 est limité par une butée B2 prévue à l'intérieur de l'évidement 12a.The movement of the control rod 11 inside the sheath 12 is limited by a stop B2 provided inside the recess 12a.
Ainsi la tige 11 peut coulisser librement à l'intérieur du fourreau, lors des mouvements de pivotement du collier 4 vers l'avant, qui se produisent lors de la pratique normale. Ce libre débattement de la tige est illustré par l'angle α sur la figure 3. A partir d'une certaine position de basculement vers l'arrière du collier 4, l'extrémité supérieure de la tige 1 1 viendra en appui contre la butée B2 et sera actionnée par celle-ci vers le bas afin de déclencher le système de freinage 10, ainsi que cela sera expliqué plus loin.Thus the rod 11 can slide freely inside the sheath, during the pivoting movements of the collar 4 forwards, which occur during normal practice. This free movement of the rod is illustrated by the angle α in Figure 3. From a certain tilting position towards the rear of the collar 4, the upper end of the rod 1 1 will come to bear against the stop B2 and will be actuated by it downwards in order to trigger the braking system 10, as will be explained below.
Comme le montre plus particulièrement la figure 6, la biellette 8 et le palonnierAs shown more particularly in Figure 6, the link 8 and the lifter
7 forment une articulation à genouillère 20 dont les trois axes sont constitués par les axes x2, x3 et x4 dont la ligne de point mort N est celle passant par les axes d'articulation x2 et x3.7 form a toggle joint 20 the three axes of which are constituted by the axes x2, x3 and x4 whose neutral line N is that passing through the axes of articulation x2 and x3.
Comme cela est connu dans une articulation à genouillère de blocage/ déblocage l'ensemble s'obtient en faisant passer l'axe x4 de part et d'autre de l'axe neutre ou ligne de point mort N.As is known in a locking / unlocking toggle joint, the assembly is obtained by passing the x4 axis on either side of the neutral axis or neutral line N.
En l'occurrence la position de blocage de la genouillère 20 est celle montrée à la figure 6, obtenue par pivotement de la biellette 8, commandée par la tige de commande 1 1 , dans le sens anti horaire jusqu'à venir en appui contre une butée B1.In this case the locking position of the toggle joint 20 is that shown in Figure 6, obtained by pivoting the rod 8, controlled by the control rod 1 1, counterclockwise until it comes to bear against a stop B1.
Dans cette position, qui correspond à une position de roulage normale du patin telle que montrée à la figure 2, la roue arrière 3 est pivotée au maximum vers le bas et se trouve sur un même plan de roulement que les autres roues 15, 16, 17.In this position, which corresponds to a normal rolling position of the skate as shown in FIG. 2, the rear wheel 3 is pivoted as far as possible downwards and is on the same running surface as the other wheels 15, 16, 17.
Un ou plusieurs ressorts de rappel R, interposés entre l'extension 18 du châssis et la biellette 8, et agissant perpendiculairement à l'axe neutre de la genouillère, exercent un effort de rappel de la biellette 8 contre la butée et garantissent donc un parfait maintien en place de ladite biellette en position de roulage du patin.One or more return springs R, interposed between the extension 18 of the chassis and the link 8, and acting perpendicularly to the neutral axis of the toggle joint, exert a return effort of the link 8 against the stop and therefore guarantee perfect holding in place of said rod in the running position of the skate.
Le fonctionnement du système de freinage 10 selon l'invention va maintenant être décrit en liaison avec les figures.The operation of the braking system 10 according to the invention will now be described in conjunction with the figures.
Comme indiqué précédemment, en position de roulage normale représentée à la figure 2, la genouillère 20 se trouve dans la position de blocage de la figure 6, et la roue arrière 3 se trouve sur le même plan de roulement que les autres roues 15, 16, 17, en contact avec le sol 14.As indicated above, in the normal rolling position shown in FIG. 2, the toggle joint 20 is in the locking position of FIG. 6, and the rear wheel 3 is on the same running surface as the other wheels 15, 16 , 17, in contact with the ground 14.
Dans cette position, le patineur peut faire pivoter sa cheville et donc le collier 4 de la chaussure selon un angle de débattement limité α, sans déclenchement intempestif de la genouillère 20 par la tige de commande 11.In this position, the skater can pivot his ankle and therefore the collar 4 of the shoe according to a limited angle of movement α, without inadvertent triggering of the toggle 20 by the control rod 11.
Lorsqu'une action de freinage est souhaitée, le patineur fait basculer sa cheville vers l'arrière et corrélativement le collier 4 de la chaussure, en décalant le pied porteur du système de freinage vers l'avant, comme montré par la flèche F1 sur la figure 4.When a braking action is desired, the skater tilts his ankle back and correspondingly the collar 4 of the shoe, by shifting the support foot of the braking system forwards, as shown by the arrow F1 on the figure 4.
De ce fait, le collier 4 vient prendre appui sur la tige 11 par l'intermédiaire de la butée B2 du fourreau 12 et provoque une translation de celle-ci vers le bas, comme indiqué par la flèche F2 sur la figure 4.As a result, the collar 4 comes to bear on the rod 11 by means of the stop B2 of the sleeve 12 and causes it to translate downwards, as indicated by the arrow F2 in FIG. 4.
Corrélativement, la tige 1 1 entraîne la biellette 8 dans un mouvement de pivotement dans le sens horaire par rapport à son axe d'articulation x3 sur le châssis, comme indiqué par la flèche F3 sur la figure 5.Correlatively, the rod 1 1 drives the link 8 in a pivoting movement clockwise with respect to its axis of articulation x3 on the chassis, as indicated by the arrow F3 in FIG. 5.
Ce mouvement a pour effet de faire passer l'axe x4 de l'autre côté de la ligne de point mort N et de casser la genouillère 20 constituée par le palonnier 7, la butée B1 et la biellette 8, en faisant remonter la roue 3 articulée sur le palonnier 7, comme indiqué par la flèche F4 sur les figures 5 et 6. La roue arrière 3 s'escamote donc vers le haut par rapport aux autres roues 15, 16, 17 et les roues ne sont plus alignées.This movement has the effect of passing the axis x4 on the other side of the neutral line N and breaking the toggle 20 constituted by the lifter 7, the stop B1 and the link 8, by raising the wheel 3 articulated on the lifting beam 7, as indicated by arrow F4 in FIGS. 5 and 6. The rear wheel 3 therefore retracts upward relative to the other wheels 15, 16, 17 and the wheels are no longer aligned.
Comme le montre la figure 5, la roue 15 située en avant de la roue 3 reste constamment en contact avec le sol, alors que les roues avant 16, 17 se soulèvent, et permet donc de conserver une bonne stabilité lors du freinage en fournissant avec le patin de frein 13 une surface d'appui augmentée, par rapport à un système de freinage normal ou la surface d'appui est fournie par la roue la plus arrière et le patin de freinage.As shown in FIG. 5, the wheel 15 located in front of the wheel 3 remains constantly in contact with the ground, while the front wheels 16, 17 are raised, and therefore makes it possible to maintain good stability during braking by providing with the brake shoe 13 has an increased bearing surface, compared to a normal braking system or the bearing surface is provided by the rearmost wheel and the brake shoe.
L'effort de freinage peut alors se poursuivre par soulèvement des roues 16, 17, par pivotement par rapport au nouveau point d'appui constitué par la roue 15, sous l'effet du poids et de la position du patineur, permettant ainsi de moduler aisément la puissance de freinage en fonction de l'effort F1 fourni vers l'arrière.The braking force can then continue by lifting the wheels 16, 17, by pivoting relative to the new fulcrum formed by the wheel 15, under the effect of the weight and the position of the skater, thus allowing to modulate easily the braking power as a function of the force F1 supplied towards the rear.
Bien entendu la roue 3 redescend dès que le collier 4 est pivoté suffisamment vers l'avant, entraînant une rotation dans le sens anti-horaire de la biellette 8.Of course, the wheel 3 goes back down as soon as the collar 4 is pivoted sufficiently forwards, causing a rotation in the counterclockwise direction of the link 8.
Afin d'augmenter encore l'effort de freinage fourni par le patineur, une butée B3 peut être prévue sur le châssis ou son extension 18 pour fournir à l'étrier 19 un appui sur ladite extension 18 et donc une transmission directe en direction du sol des efforts exercés par la cheville sur le patin de frein 13. Une telle disposition permet d'obtenir le maximum de puissance de freinage.In order to further increase the braking force provided by the skater, a stop B3 can be provided on the chassis or its extension 18 to provide the caliper 19 with support on said extension 18 and therefore direct transmission towards the ground forces exerted by the ankle on the brake shoe 13. Such an arrangement makes it possible to obtain the maximum braking power.
Comme montré aux figures 4 et 5, la butée B3 peut être soit fixe (figure 5) soit réglable et constituée en l'occurrence par une vis (figure 4).As shown in Figures 4 and 5, the stop B3 can be either fixed (Figure 5) or adjustable and in this case constituted by a screw (Figure 4).
La figure 5 montre l'amplitude de mouvement maximum du collier 4 vers l'arrière, avec venue en butée contre B3 et escamotage de la roue 3 de façon que cette dernière ne se trouve plus en contact avec le sol, pour un freinage optimum.Figure 5 shows the maximum range of movement of the collar 4 backwards, with abutment against B3 and retraction of the wheel 3 so that the latter is no longer in contact with the ground, for optimum braking.
De préférence, la tige 1 1 sera également réglable au niveau de l'étrier 9 de façon à permettre de régler l'angle ou la position à partir de laquelle elle commandera le pivotement de la biellette 8 et donc le déverrouillage de la genouillère 20 par le collier 4.Preferably, the rod 1 1 will also be adjustable at the level of the stirrup 9 so as to make it possible to adjust the angle or the position from which it will control the pivoting of the rod 8 and therefore the unlocking of the toggle joint 20 by the collar 4.
Comme montré à la figure 6, le système de freinage 10 par escamotage de la roue 3 peut être neutralisé en prévoyant un moyen de blocage V de la biellette 8, qui s'oppose à la rotation de celle-ci dans le sens horaire et verrouille donc le système de freinage de manière permanente.As shown in Figure 6, the braking system 10 by retraction of the wheel 3 can be neutralized by providing a locking means V of the rod 8, which opposes the rotation thereof clockwise and locks so the braking system permanently.
Dans un tel cas de figure, la roue 3 est maintenue dans une position de roulage permanent et les éléments de commande constitués par la tige 1 1 , le fourreau 12 et l'étrier 9 peuvent être supprimés.In such a case, the wheel 3 is maintained in a permanent rolling position and the control elements constituted by the rod 11, the sheath 12 and the stirrup 9 can be omitted.
Un tel système de freinage 10 peut donc accompagner l'évolution du patineur et être neutralisé facilement lorsque celui-ci atteint un niveau suffisant lui permettant de s'en passer. Les figures 7, 8 et 9 illustrent un autre mode de réalisation permettant de rendre encore plus efficace le freinage.Such a braking system 10 can therefore accompany the evolution of the skater and be easily neutralized when the latter reaches a sufficient level allowing him to do without it. Figures 7, 8 and 9 illustrate another embodiment to make braking even more effective.
Dans ce cas, la fourche 5 est munie au niveau de son extrémité 5a d'un prolongement 5c sur lequel est monté un élément de freinage rotatif 21 , constitué par exemple par un galet en caoutchouc.In this case, the fork 5 is provided at its end 5a with an extension 5c on which is mounted a rotary braking element 21, constituted for example by a rubber roller.
Le prolongement 5c forme un coude par rapport à l'ensemble de la fourche 5, de façon à positionner le galet 21 à proximité de la périphérie de la roue 15 située en avant de la roue 3.The extension 5c forms an elbow relative to the assembly of the fork 5, so as to position the roller 21 near the periphery of the wheel 15 situated in front of the wheel 3.
Lors du freinage, la fourche 5 pivote dans le sens anti-horaire par rapport à l'axe x1 et vient donc appliquer le galet rotatif 21 contre la roue 15 ; elle-même en contact avec le sol, freinant ainsi la rotation de ladite roue 15.During braking, the fork 5 pivots anti-clockwise with respect to the axis x1 and therefore comes to apply the rotary roller 21 against the wheel 15; itself in contact with the ground, thus braking the rotation of said wheel 15.
Cette action de freinage sur la roue 15 vient alors s'ajouter à l'action de freinage du patin 13 sur le sol.This braking action on the wheel 15 is then added to the braking action of the shoe 13 on the ground.
Le système de freinage 10 permet donc de freiner en même temps sur le sol et sur une roue 15, tout en escamotant la roue arrière 3.The braking system 10 therefore makes it possible to brake at the same time on the ground and on a wheel 15, while retracting the rear wheel 3.
De préférence, l'élément rotatif 21 est prévu de façon à freiner la roue 15 sans la bloquer, par compression du caoutchouc constituant le galet, de façon à ne pas user prématurément ladite roue.Preferably, the rotary element 21 is provided so as to brake the wheel 15 without blocking it, by compression of the rubber constituting the roller, so as not to prematurely wear said wheel.
Bien entendu la présente invention n'est pas limitée aux modes de réalisation décrits à titre d'exemples non limitatifs, elle s'applique notamment aussi bien aux patins à roues en ligne qu'aux patins à roulettes classiques.Of course, the present invention is not limited to the embodiments described by way of nonlimiting examples, it applies in particular to both inline skates and conventional roller skates.
Elle englobe également tous les équivalent techniques permettant de résoudre le même problème ou procédant de la même idée inventive.It also encompasses all the technical equivalents enabling the same problem to be solved or proceeding from the same inventive idea.
C'est ainsi que plusieurs roues pourraient être prévues escamotables ou que la direction d'escamotage pourrait être différente de celle décrite. Par ailleurs, la construction de la chaussure pourrait être différente et par exemple dépourvue de collier articulé, sans que l'on sorte pour autant du cadre de la présente invention. Thus, several wheels could be provided retractable or the direction of retraction could be different from that described. Furthermore, the construction of the shoe could be different and for example devoid of an articulated collar, without departing from the scope of the present invention.
