Description

SYSTEME DE FREINAGE POUR ROLLER BRAKE SYSTEM FOR ROLLER
L'invention est relative à un roller équipé d'un système de freinage.The invention relates to a roller equipped with a braking system.
Elle trouvera son application en milieu industriel, chez les fabricants d'équipements sportifs, notamment les fabricants de rollers, et sera commercialisée tout particulièrement dans les surfaces de vente d'équipements sportifs.It will find its application in an industrial environment, at the manufacturers of sports equipment, in particular the manufacturers of rollers, and will be marketed especially in the sales areas of sports equipment.
Il est connu notamment deux types de rollers, à savoir les rollers en ligne constitués de trois ou quatre roues disposées en ligne les unes derrière les autres, et les rollers, plus couramment appelé patin à roulettes, de type « quad », c'est-à-dire constitués de deux axes de rotation transversaux, l'un disposé en amont et l'autre en aval du roller, chaque axe recevant à ses deux extrémités une roue. En outre, selon ces deux types de rollers, ceux-ci comprennent un châssis constitué d'une platine longitudinale sur laquelle sont montés en ligne les éléments roulant c'est-à-dire les roues voire les paires de roues disposées en ligne. En outre, le châssis comprend un dispositif de blocage du pied pour la solidarisation de celui-ci avec le roller. Ce dispositif de blocage du pied peut être, par exemple, constitué d'un élément chaussant permettant soit la réception du pied, soit le blocage d'une chaussure adaptée et portée au pied du patineur.It is known in particular two types of rollers, namely in-line rollers consisting of three or four wheels arranged in line one behind the other, and rollers, more commonly called roller skate, type "quad" is that is to say consist of two transverse axes of rotation, one disposed upstream and the other downstream of the roller, each axis receiving at both ends a wheel. In addition, according to these two types of rollers, these comprise a frame consisting of a longitudinal plate on which are mounted in line the rolling elements that is to say the wheels or pairs of wheels arranged in line. In addition, the frame includes a foot locking device for securing it with the roller. This foot locking device may be, for example, consisting of a footwear element allowing either the reception of the foot, or the blocking of a suitable shoe and worn on the skater's foot.
L'homme du métier du domaine de l'invention a connaissance des rollers équipés d'un système de freinage dont le principe de fonctionnement est tel que celui décrit dans le document FR 2 753 106. A ce titre, le roller décrit dans le document FR 2 753 106 comprend une platine sur laquelle sont montées en ligne des roues ; un système de freinage, comprenant un élément de freinage du type patin, voire galet, est agencé sous la platine, au-dessus d'au moins l'une des roues, notamment en partie arrière. En outre, selon cette conception, un dispositif d'actionnement est constitué d'une tige comportant au moins deux parties articulées entre elles au niveau des malléoles, suivant un axe de pivotement transversal, la première partie enveloppant au moins le talon du pied et la seconde partie enveloppant au moins la portion inférieure du mollet, ladite seconde partie de la tige étant apte à pivoter par rapport à ladite première partie pour activer le système de freinage permettant le déplacement vertical du patin de freinage pour le mettre en contact avec la ou les roues arrières du roller et freiner celles-ci. Un tel système de freinage présente un risque pour l'utilisateur, notamment lorsque celui-ci ne contrôle pas le freinage, et en particulier le mouvement de sa jambe actionnant ladite seconde partie de la tige qui agit sur le système de freinage. Selon une telle conception de roller, l'utilisateur ne dispose pas d'une stabilité optimale, celui-ci pouvant basculer vers l'avant ; dès lors il existe un risque de chute du patineur en cours du freinage.Those skilled in the field of the invention are aware of rollers equipped with a braking system whose operating principle is such as that described in document FR 2 753 106. As such, the roller described in document FR 2 753 106 comprises a plate on which wheels are mounted in line; a braking system, comprising a braking element of the shoe type, or even roller, is arranged under the plate, above at least one of the wheels, in particular at the rear. In addition, according to this design, an actuating device consists of a rod comprising at least two parts articulated to each other at the level of the malleoli, along an axis of transverse pivoting, the first part enveloping at least the heel of the foot and the second part enveloping at least the lower portion of the calf, said second part of the shaft being able to pivot relative to said first part to activate the braking system allowing the vertical displacement of the braking pad to bring it into contact with the rear wheel or wheels of the roller and to brake them. Such a braking system presents a risk for the user, especially when the latter does not control the braking, and in particular the movement of his leg actuating said second portion of the rod which acts on the braking system. According to such a design of roller, the user does not have optimal stability, it can tilt forward; therefore, there is a risk of falling the skater during braking.
L'objet de la présente invention est de mettre en œuvre un roller palliant notamment les inconvénients décrits ci-dessus pour la conception des rollers semblables à ceux décrits dans le document FR 2 753 106. A ce titre, l'invention concerne un roller, également dénommé patin à roulettes, permettant une autorégulation du freinage. Lors d'une bascule du patineur vers l'avant, la pression exercée au niveau de son talon diminue, réduisant ainsi l'efficacité du freinage et évitant tout déséquilibre vers l'avant.The object of the present invention is to implement a roller bearing in particular the disadvantages described above for the design of rollers similar to those described in document FR 2 753 106. As such, the invention relates to a roller, also called roller skate, allowing self-regulation of braking. When the skater moves forward, heel pressure decreases, reducing braking efficiency and preventing forward imbalance.

The braking system comprises at least one braking element, in particular a pad or a roller, arranged close to at least one of the rolling elements, the braking element being able to come into contact with the wheel of this element. rolling to brake the roller. The chassis comprises a plate arranged to receive the rolling elements, in particular the axes of rotation of the wheels which are mounted transversely, or even said wheels, these being notably housed inside the plate in the case where the roller includes four wheels in line. Furthermore, a footwear element is arranged above the plate, the latter being adapted to receive a foot or a shoe of the skater. This footwear element is provided with a device for actuating the braking system, the activation of the actuating device making it possible to act on the braking system to brake the roller.
De manière remarquable, le système de freinage comprend une pièce de support de l'élément de freinage. Cette pièce de support est montée coulissant par rapport à la platine pour translater l'élément de freinage d'une position dégagée de la ou des roues, à une position de contact avec celles-ci, voire inversement. Par ailleurs, le système de freinage comprend un dispositif de transmission apte à se déplacer d'une position passive à une position active, ou inversement, sous l'action du dispositif d'actionnement. Ce dispositif de transmission est agencé, d'une part, pour maintenir dégager l'élément de freinage vis-à-vis de la roue dans la position passive quelle que soit l'action du poids exercée par le patineur et, d'autre part, pour autoriser le coulissement de la pièce de support par rapport au châssis dans la position active selon laquelle le dispositif de transmission est apte à prendre appui sur la pièce support sous l'action du poids du patineur exerçant une pression avec le talon, pour permettre le coulissement de la pièce de support et ainsi le freinage du roller.Remarkably, the braking system comprises a support piece of the braking element. This support piece is slidably mounted relative to the plate to translate the braking element from a position released from the wheel or wheels, to a position of contact therewith, or vice versa. Furthermore, the braking system comprises a transmission device capable of moving from a passive position to an active position, or vice versa, under the action of the actuating device. This transmission device is arranged, on the one hand, to keep the braking element free from the wheel in the passive position regardless of the action of the weight exerted by the skater and on the other hand , to allow the sliding of the support member relative to the frame in the active position in which the transmission device is able to bear on the support piece under the action of the weight of the skater exerting pressure with the heel, to allow the sliding of the support piece and thus the braking of the roller.
Ainsi, l'action du poids exercée par le patineur sur le dispositif de transmission reste sans effet sur la pièce de support de l'élément de freinage tant que ledit dispositif de transmission n'a pas été activé au préalable par le dispositif d'actionnement. C'est donc seulement lors d'une action volontaire et maîtrisée du patineur, lorsque celui-ci agit sur le dispositif d'actionnement, que le dispositif de transmission en position active pourra être actionné sous l'action du poids du patineur pour translater la pièce support assujettie à l'élément de freinage. On garantit ainsi un parfait contrôle lors du freinage. De manière préférentielle, le dispositif de transmission comprend un élément poussoir agencé sur la platine. Cet élément poussoir est apte à se déplacer verticalement sous l'action d'un effort exercé par le talon du patineur, lorsque le dispositif de transmission se situe en position active, ledit élément poussoir agissant alors de manière directe ou indirecte sur la pièce de support pour la pousser et réaliser son coulissement vers le bas.Thus, the action of the weight exerted by the skater on the transmission device has no effect on the support piece of the braking element until said transmission device has not been activated beforehand by the actuating device. . It is therefore only during a voluntary and controlled action of the skater, when it acts on the actuating device, that the transmission device in the active position can be actuated under the action of the weight of the skater to translate the support piece subject to the braking element. This guarantees perfect control during braking. Preferably, the transmission device comprises a pusher element arranged on the plate. This pusher element is able to move vertically under the action of a force exerted by the heel of the skater, when the transmission device is in the active position, said pusher element then acting directly or indirectly on the support piece to push it and make it slide down.
En outre, le dispositif de transmission comprend au moins une came et un élément de liaison, ledit élément de liaison étant raccordé entre la came et le dispositif d'actionnement. Cette came est mobile vis-à- vis de la platine et de la pièce de support, de manière à être déplacée d'une position passive à une position active lorsque l'élément de liaison est actionné par le dispositif d'actionnement. Selon la position active de la came, l'élément poussoir est capable de se déplacer vers le bas et d'agir sur la pièce de support, lorsque le patineur exerce une poussée sur ledit élément poussoir avec le talon ; la pièce de support coulisse alors verticalement, entraînant l'élément de freinage qui vient au contact de la roue de l'élément roulant.In addition, the transmission device comprises at least one cam and a connecting element, said connecting element being connected between the cam and the actuating device. This cam is movable with respect to the plate and the support piece, so as to be moved from a passive position to an active position when the connecting element is actuated by the actuating device. Depending on the active position of the cam, the pusher member is capable of moving downwardly and acting on the support member, when the skater pushes on said pusher member with the heel; the support piece then slides vertically, driving the braking element which comes into contact with the wheel of the rolling element.
De manière préférentielle et non limitative, l'élément de freinage est constitué d'un galet. Ce galet dispose en outre d'un profil agencé pour présenter au moins deux points de contact avec la roue ; ces points de contact sont situés à des rayons différents, ce qui permet d'exercer un frottement direct par friction entre le galet et la roue.In a preferential and nonlimiting manner, the braking element consists of a roller. This roller also has a profile arranged to have at least two points of contact with the wheel; these contact points are located at different radii, which makes it possible to exert a direct friction by friction between the roller and the wheel.
De manière préférentielle et non limitative, le dispositif d'actionnement du système de freinage est constitué d'une tige qui comporte au moins deux parties articulées entre elles, notamment au niveau des malléoles, suivant un axe de pivotement transversal. La première partie enveloppe au moins le talon du pied, voire la partie arrière de l'élément chaussant recevant le pied ou une chaussure. La seconde partie enveloppe au moins la portion inférieure du mollet et, de préférence, également la portion inférieure du tibia. Le pivotement de la seconde partie de la tige lors d'un mouvement de la jambe permet d'actionner le système de freinage. Selon une variante, ce dispositif d'actionnement peut être constitué d'une pièce de liaison agencée sous l'extrémité avant de l'élément chaussant ou de la chaussure, cette pièce de liaison étant reliée au système de freinage pour agir sur celui-ci. Selon un premier mode de conception du roller, celui-ci comprend quatre roues montées en ligne les unes derrière les autres sur la platine, le système de freinage comportant un élément de freinage qui est apte à entrer en contact avec les deux roues arrières du roller.In a preferential and nonlimiting manner, the actuating device of the braking system consists of a rod which comprises at least two parts hinged together, particularly at the level of the malleoli, along a transverse axis of pivoting. The first part wraps at least the heel of the foot, or even the rear part of the footwear element receiving the foot or shoe. The second portion envelopes at least the lower portion of the calf and, preferably, also the lower portion of the tibia. The pivoting of the second part of the stem during a movement of the leg makes it possible to actuate the braking system. According to a variant, this actuating device may consist of a connecting piece arranged under the front end of the footwear element or the boot, this connecting piece being connected to the braking system to act on it. . According to a first design mode of the roller, it comprises four wheels mounted in line one behind the other on the plate, the braking system comprising a braking element which is able to come into contact with the two rear wheels of the roller .
Selon une variante de conception du roller, selon laquelle ledit roller est plus couramment appelé patin à roulettes, voire roller « quad », celui-ci comprend deux paires de roues disposées aux extrémités avant et arrière de la platine. En outre, le système de freinage comporte deux éléments de freinage disposés chacun au niveau de la paire de roues arrières pour entrer en contact avec celles-ci sous l'action du système de freinage activé par le dispositif d'actionnement.According to a variant of roller design, according to which said roller is more commonly called roller skate, or even roller "quad", it comprises two pairs of wheels arranged at the front and rear ends of the plate. In addition, the braking system comprises two braking elements each arranged at the level of the pair of rear wheels to come into contact therewith under the action of the braking system activated by the actuating device.
D'autres caractéristiques de la présente invention apparaîtront à la lecture de Ia description qui va suivre, à l'appui de figures parmi lesquelles : la figure 1 représente partiellement une vue d'ensemble des éléments constitutifs du roller, selon un mode préférentiel de conception ; la figure 2 représente une vue détaillée en coupe d'un mode préférentiel de conception du système de freinage du roller ; - la figure 3 représente une vue d'ensemble du système de freinage tel qu'illustré en figure 2 ; la figure 4 représente une vue partielle des éléments constituant le système de freinage selon les figures 2 et 3 ; la figure 5 schématise une variante de conception du système de freinage du roller.Other features of the present invention will appear on reading the following description, in support of figures, of which: FIG. 1 partially represents an overview of the constituent elements of the roller, according to a preferred mode of design ; FIG. 2 represents a detailed sectional view of a preferred mode of design of the roller brake system; FIG. 3 represents an overall view of the braking system as illustrated in FIG. 2; FIG. 4 represents a partial view of the elements constituting the braking system according to FIGS. 2 and 3; Figure 5 shows a variant of the design of the roller brake system.
Le roller 1 , illustré notamment sur la figure 1 , comprend un châssis 3. Ce châssis 3 comprend notamment une platine 11 présentant une forme longitudinale, de préférence telle qu'illustrée en figure 1 , cette platine 11 étant agencée pour recevoir des éléments roulants 5, 7 dont la conception peut varier. En effet, tel qu'illustré sur les figures 1 à 5, correspondant à un mode préférentiel de conception du roller, celui-ci comprend quatre roues 5a, 7a, 8a, 10a disposées en ligne les unes derrière les autres, ces roues étant montées en rotation suivant un axe de rotation transversal 12 sur la platine 11. On peut toutefois envisager une variante de conception du roller selon laquelle les éléments roulants 5, 7 sont constitués d'une paire de roues montées en rotation suivant un axe, voire deux axes coaxiaux, sur les côtés latéraux de la platine, lesdites paires de roues étant montées en ligne sur la platine à ses extrémités avant et arrière. Selon cette variante le roller est plus couramment dénommé patin à roulette ou roller « quad ». Par ailleurs, le roller 1 comprend un système de freinage 9. Ce système de freinage 9 comporte notamment un élément de freinage 31. Lorsque le roller 1 présente une conception telle qu'illustrée sur les figures 1 à 5, cet élément de freinage 21 est constitué d'un seul galet 21a qui est agencé au niveau de l'extrémité arrière de la platine 11 , et disposé au- dessus des roues arrières 5a, 7a, ce galet 21a étant apte à venir en contact avec les roues 5a, 7a. Par ailleurs, ce galet 21a est monté rotatif par rapport à la platine 11 et il est agencé pour venir directement en contact sur les deux roues arrières 5a, 7a sans utilisation de moyens complémentaires permettant de freiner ledit galet 21a lorsqu'il entre en contact avec les roues. Pour cela, le galet 21a présente un profil qui est agencé pour présenter au moins deux points de contact avec chacune des roues 5a, 7a, ces deux points de contact sur la roue 5a, ainsi que sur la roue 7a, étant situés à des rayons différents, ce qui permet d'exercer un frottement direct par friction entre le galet et chacune des roues, ce frottement par friction entraînant le freinage desdites roues 5a, 7a et donc le freinage du roller. Selon une variante de conception du roller, lorsque celui-ci comprend deux paires de roues disposées en ligne aux extrémités avant et arrière sur la platine 11 , l'élément de freinage 21 est alors constitué de deux galets agencés au-dessus de chacune des roues arrières, ces galets comprenant également un profil agencé pour présenter au moins deux points de contact sur chacune des deux roues arrières, ces points de contact étant situés à des rayons différents pour exercer également un frottement direct par friction entre les galets et les roues.The roller 1, illustrated in particular in Figure 1, comprises a frame 3. This frame 3 comprises in particular a plate 11 having a longitudinal shape, preferably as shown in Figure 1, the plate 11 being arranged to receive rolling elements 5, 7 whose design may vary. Indeed, as illustrated in Figures 1 to 5, corresponding to a preferred mode of design of the roller, it comprises four wheels 5a, 7a, 8a, 10a disposed in line one behind the other, these wheels being mounted in rotation along an axis of transverse rotation 12 on the plate 11. However, it is possible to envisage an alternative design of the roller according to which the rolling elements 5, 7 consist of a pair of wheels mounted in rotation along an axis, or even two axes. coaxial, on the lateral sides of the plate, said pairs of wheels being mounted in line on the plate at its front and rear ends. According to this variant, roller is more commonly referred to as roller skate or "quad" roller. In addition, the roller 1 comprises a braking system 9. This braking system 9 comprises in particular a braking element 31. When the roller 1 has a design as illustrated in FIGS. 1 to 5, this braking element 21 is consisting of a single roller 21a which is arranged at the rear end of the plate 11, and disposed above the rear wheels 5a, 7a, the roller 21a being adapted to come into contact with the wheels 5a, 7a. Furthermore, this roller 21a is rotatably mounted relative to the plate 11 and is arranged to come into direct contact with the two rear wheels 5a, 7a without the use of additional means for braking said roller 21a when it comes into contact with the wheels. For this, the roller 21a has a profile which is arranged to have at least two points of contact with each of the wheels 5a, 7a, these two points of contact on the wheel 5a, as well as on the wheel 7a, being located at radii different, which allows to exert a direct friction by friction between the roller and each wheel, friction friction causing the braking of said wheels 5a, 7a and thus the braking of the roller. According to a variant of roller design, when it comprises two pairs of wheels arranged in line at the front and rear ends on the plate 11, the braking element 21 is then constituted by two rollers arranged above each of the rear wheels, these rollers also comprising an arranged profile to present at least two points of contact on each of the two rear wheels, these contact points being located at different radii to also exert direct friction by friction between the rollers and the wheels.
Tel qu'illustré sur les figures 1 , 2 et 5, le châssis 3 comprend un élément chaussant 13 qui est agencé au-dessus de la platine 11. Cet élément chaussant est agencé pour recevoir une chaussure adaptée au pied du patineur. Pour cela, l'élément chaussant13 comprend des moyens de fixation de la chaussure du patineur sur la platine 11. Il est toutefois possible de concevoir un élément chaussant constitué directement par une chaussure pour la réception du pied du patineur. L'élément chaussant est muni d'un dispositif d'actionnement qui est agencé pour agir sur le système de freinage 9, permettant d'actionner le galet de freinage 21a et de le mettre en contact avec la ou les roues 5a, 7a.As illustrated in Figures 1, 2 and 5, the frame 3 comprises a footwear element 13 which is arranged above the plate 11. This footwear element is arranged to receive a shoe adapted to the skater's foot. For this, the footwear element13 comprises means for fixing the shoe of the skater on the plate 11. It is however possible to design a footwear element formed directly by a shoe for receiving the foot of the skater. The footwear element is provided with an actuating device which is arranged to act on the braking system 9, for actuating the braking roller 21a and putting it in contact with the wheel or wheels 5a, 7a.
Selon la conception du roller 1 illustré aux figures 1 à 5, le dispositif d'actionnement du système de freinage est constitué d'au moins deux parties 15 et 17 articulées entre elles. La première partie inférieure 15 est solidaire de la platine 11 et est disposée à son extrémité arrière ; cette partie inférieure 15 est notamment agencée pour envelopper le talon, c'est-à-dire qu'elle réceptionne la partie arrière de la chaussure fixée sur la platine 11. Par ailleurs, la seconde partie 17 supérieure est articulée avec la partie inférieure 15, l'articulation se faisant suivant un axe de pivotement 19 positionné notamment au niveau des malléoles de la cheville du patineur. En outre, cette seconde partie 17 est agencée pour envelopper de préférence la portion inférieure du mollet, ainsi que la portion inférieure du tibia. Lorsque la seconde partie supérieure 17 pivote par rapport à la première partie inférieure 15, ledit pivotement permet d'actionner le système de freinage 9 tel que cela sera décrit ci-après.According to the design of the roller 1 illustrated in Figures 1 to 5, the actuating device of the braking system consists of at least two parts 15 and 17 hinged together. The first lower portion 15 is integral with the plate 11 and is disposed at its rear end; this lower part 15 is in particular arranged to envelop the heel, that is to say, it receives the rear part of the shoe fixed on the plate 11. Moreover, the second upper portion 17 is articulated with the lower part 15 , the articulation being along a pivot axis 19 positioned in particular at the malleoli of the skater's ankle. In addition, this second portion 17 is arranged to wrap preferably the lower portion of the calf, and the lower portion of the tibia. When the second upper portion 17 pivots with respect to the first lower portion 15, said pivoting makes it possible to actuate the braking system 9 as will be described below.
Le système de freinage 9 comprend une pièce de support 23 sur laquelle est fixé l'élément de freinage 11. Concernant le mode de conception illustré sur les figures 1 à 5, le galet de freinage 21a est agencé à l'extrémité inférieure de cette pièce de support 23. Pour cela, la pièce de support 23 reçoit le galet 21a monté en rotation sur celui-ci au niveau d'un axe de pivotement 24 agencé au niveau de son extrémité inférieure. Par ailleurs, cette pièce de support 23 est montée coulissante par rapport à la platine 11 , ledit coulissement permettant de préférence de translater verticalement l'élément de freinage d'une première position selon laquelle il est dégagé des roues 5a, 7a vers une seconde position selon laquelle il est en contact avec lesdites roues, ou inversement. Ainsi, lorsque la pièce de support 23 est translatée vers le haut, le galet 21a est dégagé des roues 5a, 7a. Au contraire, lorsque la pièce de support 23 est translatée vers le bas, ledit galet est en contact avec lesdites roues 5a, 7a. Lorsque le roller est du type « quad », c'est-à-dire constitué de paires de roues disposées aux extrémités avant et arrière sur la platine 11 , cette pièce support 23 est apte à supporter les deux galets de freinage de manière à les translater simultanément d'une position dégagée par rapport aux roues arrières, lorsque ladite pièce de support 23 est translatée vers le haut, vers une position de contact des galets avec les roues arrières, lorsque ladite pièce de support 23 est translatée vers le bas.The braking system 9 comprises a support piece 23 on which the braking element 11 is fixed. With regard to the design mode illustrated in FIGS. 1 to 5, the braking roller 21a is arranged at the lower end of this piece. 23. For this, the support member 23 receives the roller 21a rotatably mounted thereon at a pivot axis 24 arranged at its lower end. Furthermore, this support piece 23 is slidably mounted relative to the plate 11, said sliding preferably for vertically translating the braking element from a first position in which the wheels 5a, 7a are disengaged towards a second position. according to which it is in contact with said wheels, or conversely. Thus, when the support piece 23 is translated upwards, the roller 21a is disengaged from the wheels 5a, 7a. On the contrary, when the support piece 23 is translated downwards, said roller is in contact with said wheels 5a, 7a. When the roller is of the "quad" type, that is to say consisting of pairs of wheels arranged at the front and rear ends on the plate 11, this support piece 23 is able to support the two braking rollers so as to simultaneously translate from a position released relative to the rear wheels, when said support member 23 is translated upwards, to a contact position of the rollers with the rear wheels, when said support member 23 is translated downwards.
Par ailleurs, le système de freinage 9 comprend un dispositif de transmission 25 permettant de réaliser le coulissement de la pièce de support 23. Pour cela, le dispositif de transmission 25 est apte à se déplacer selon deux positions, à savoir une première position passive selon laquelle le galet de freinage est maintenu dégagé vis-à-vis des roues 5a, 7a, et une seconde position active selon laquelle ledit dispositif de transmission autorise le coulissement de la pièce support 23 par rapport au châssis 3 ou à la platine 11. Dans cette position active, le dispositif de transmission 25 est apte à prendre appui sur la pièce support 23 sous l'action exercée par le poids du patineur, ledit appui permettant de coulisser la pièce support 23 vers le bas.Furthermore, the braking system 9 comprises a transmission device 25 making it possible to slide the support piece 23. For this purpose, the transmission device 25 is able to move in two positions, namely a first passive position according to which the braking roller is kept free vis-à-vis the wheels 5a, 7a, and a second active position in which said transmission device allows the sliding of the support member 23 relative to the frame 3 or the plate 11. In this active position, the transmission device 25 is able to bear on the support piece 23 under the action exerted by the weight of the skater, said support for sliding the support member 23 downwards.
Les figures 1 à 4 illustrent un mode de conception de ce dispositif de transmission 25. Celui-ci comprend un élément poussoir 41 qui est agencé sur la platine 11 pour se déplacer verticalement sous l'action d'un effort exercé par le talon du patineur. Toutefois, ce déplacement vertical de l'élément poussoir 41 est possible lorsque le dispositif de transmission 25 se situe dans la position active ; l'élément poussoir 41 est alors apte à agir sur la pièce de support 23 pour la pousser vers le bas et réaliser son coulissement entraînant le déplacement du galet 21a. Ainsi, le patineur est capable de maîtriser le freinage en exerçant une poussée plus ou moins importante sur cet élément poussoir.FIGS. 1 to 4 illustrate a mode of design of this transmission device 25. This comprises a pusher element 41 which is arranged on the plate 11 to move vertically under the action of a force exerted by the heel of the skater . However, this vertical displacement of the pusher element 41 is possible when the transmission device 25 is in the active position; the pusher element 41 is then able to act on the support piece 23 to push it downwards and make it slide causing the roller 21a to move. Thus, the skater is capable of controlling braking by exerting a greater or lesser thrust on this pusher element.
Cet élément poussoir 41 comprend un plateau 45 sur lequel le talon du patineur, voire le talon de la chaussure est capable d'appuyer. Pour cela, le plateau 45 est agencé au-dessus de la platine 11 et positionné dans la partie supérieure amont de celle-ci sous l'élément chaussant. Par ailleurs, l'élément poussoir 41 comprend un corps vertical 47, prolongeant vers le bas le plateau 45, le plateau 45 et le corps vertical 47 pouvant être constitués d'une seule pièce ou de deux pièces solidarisées entre elles. Ce corps vertical 47 est agencé pour traverser la partie supérieure amont de la platine 11 et pour agir sur la pièce support 23 lorsque le talon exerce un effort d'appui sur le plateau 45.This pusher element 41 comprises a plate 45 on which the heel of the skater, or even the heel of the shoe is capable of pressing. For this, the plate 45 is arranged above the plate 11 and positioned in the upstream upper part thereof under the footwear element. Furthermore, the pusher element 41 comprises a vertical body 47, extending downwardly the plate 45, the plate 45 and the vertical body 47 can consist of a single piece or two pieces joined together. This vertical body 47 is arranged to pass through the upstream upper part of the plate 11 and to act on the support piece 23 when the heel exerts a bearing force on the plate 45.
En outre, l'élément poussoir 41 comprend un système de rappel 49 du plateau 45. Ce système de rappel 49 est agencé pour rétracter le corps vertical 47 à l'intérieur de la platine 11 et cesser toute action sur la pièce de support 23 lorsque le patineur cesse d'appuyer sur ledit plateau 45. Ce système de rappel 49 est de préférence constitué par un élément ressort présentant une forme torique tel qu'illustré sur la figure 3, cet élément ressort étant réalisé de préférence dans une mousse souple déformable et apte à reprendre sa forme initiale lorsque la pression exercée sur le plateau 45 cesse, ce qui permet alors d'exercer une poussée vers le haut sur ledit plateau 45 au moyen de l'élément torique en mousse.In addition, the pusher element 41 comprises a return system 49 of the plate 45. This return system 49 is arranged to retract the vertical body 47 inside the plate 11 and stop any action on the support piece 23 when the skater stops pressing on said plate 45. This return system 49 is preferably constituted by a spring member having a toric shape as shown in Figure 3, this spring element being preferably made of a flexible deformable foam and adapted to return to its original shape when the pressure exerted on the plate 45 ceases, which then makes it possible to exert an upward thrust on said plate 45 by means of the foam ring element.
Le dispositif de transmission 25 comprend une came 27 et un élément de liaison 29, cet élément de liaison 29 raccordant la came 27 au dispositif d'actionnement, notamment la seconde partie supérieure 17, tel qu'illustré sur la figure 1. Cette came 27 est mobile vis-à-vis de la platine 11 et de la pièce support 23. Selon le mode illustré sur les figures 1 à 4, la came 27 est montée en translation longitudinale à l'intérieur de la platine 11 qui est agencée pour recevoir ledit élément. En outre, cette came 27 est disposée au-dessus de la pièce support 23. Tel qu'illustré sur les figures 2 et 3, la came 27 comprend une lamelle flexible 39 qui prend appui sur l'extrémité supérieure 44 de la pièce support 23. Cette lamelle flexible 39 est rigide et peu déformable au niveau de son extrémité proximale 40 tandis que, au contraire, son extrémité distale 42 est souple ou flexible, ce qui permet de la déformer et de la déplacer vers le bas. Ainsi, la translation longitudinale de la came 27 sous la platine 11 obtenue, sous l'action du dispositif d'actionnement qui exerce une poussée sur l'élément de liaison 29, permet de déplacer ladite came 27 suivant deux positions. Selon la première position dite passive, selon laquelle l'extrémité proximale 40 de la lamelle 39 est en appui sur l'extrémité supérieure 44 de la pièce de support, la rigidité de la lamelle 39 au niveau de cette extrémité proximale 40 empêche d'agir sur ladite pièce support 23. Inversement, selon la seconde position translatée de la came 27 sur la platine 11 , position dite active, selon laquelle l'extrémité distale 42 de la lamelle flexible 39 est en contact sur l'extrémité supérieure 44 de la pièce de support 23, cette extrémité distale 42 est apte à être déformée et déplacée vers le bas, l'appui exercé par cette lamelle 39 sur la pièce de support 23 permettant alors le coulissement de celle-ci vers le bas, et ainsi la mise en contact du galet 21a sur les roues 5a, 7a pour freiner le roller 1.The transmission device 25 comprises a cam 27 and a connecting element 29, this connecting element 29 connecting the cam 27 to the actuating device, in particular the second upper part 17, as illustrated in FIG. 1. This cam 27 is movable vis-à-vis the plate 11 and the support part 23. According to the mode shown in Figures 1 to 4, the cam 27 is mounted in longitudinal translation inside the plate 11 which is arranged to receive said element. In addition, this cam 27 is disposed above the support member 23. As illustrated in Figures 2 and 3, the cam 27 comprises a flexible strip 39 which bears on the upper end 44 of the support part 23 This flexible strip 39 is rigid and slightly deformable at its proximal end 40 while, on the contrary, its distal end 42 is flexible or flexible, which allows to deform and move it downwards. Thus, the longitudinal translation of the cam 27 under the plate 11 obtained, under the action of the actuating device which exerts a thrust on the connecting element 29, moves said cam 27 in two positions. According to the first so-called passive position, according to which the proximal end 40 of the lamella 39 rests on the upper end 44 of the support piece, the rigidity of the lamella 39 at this proximal end 40 prevents it from acting on said support member 23. Conversely, according to the second translated position of the cam 27 on the plate 11, so-called active position, in which the distal end 42 of the flexible strip 39 is in contact on the upper end 44 of the part 23, this distal end 42 is adapted to be deformed and moved downwards, the support exerted by this plate 39 on the support piece 23 then allowing the sliding thereof down, and thus the implementation contact of the roller 21a on the wheels 5a, 7a to brake the roller 1.
Selon une conception préférentielle du système de freinage 9, la came illustrée sur la figure 5, est montée pivotante vis-à-vis de la platine 11 suivant un axe de pivotement transversal 58, parallèle à celui de l'axe de rotation 12 des roues 5a, 7a. Cette came 60 est disposée de préférence en dessous de la pièce support 23 et est agencée pour prendre appui sur l'extrémité inférieure 62 de celle-ci, par exemple au niveau de l'axe de rotation 24 du galet de freinage 21a. La came 60 est agencée pour pivoter d'une position passive vers une position active, ou inversement. Lorsque le dispositif d'actionnement est relâché, la came 60 est en appui sur l'extrémité inférieure 62 de la pièce de support 23, empêchant alors celle-ci de coulisser verticalement vers le bas sous un effort éventuel exercé par le patineur avec le talon qui tend à translater vers le bas l'élément poussoir 41 en appui sur l'extrémité supérieure de la pièce de support 23. Inversement, lorsque le dispositif d'actionnement est enclenché, celui-ci entraîne le pivotement de la came 60 qui passe dans la position active selon laquelle ladite came 60 est dégagée vis-à-vis de l'extrémité inférieure 62 de la pièce support 23, autorisant alors celle-ci à translater vers le bas lorsqu'une poussée est exercée par le talon du patineur sur le plateau 45 de l'élément poussoir 41 qui translate vers le bas en prenant appui sur l'extrémité supérieure de la pièce support 23, celle-ci coulissant alors vers le bas, ce qui permet de mettre en contact le galet sur les roues 5a, 5b. Tel qu'illustré sur la figure 5, la came 60, selon ce mode de réalisation, comprend une forme incurvée agencée pour que, lorsque ladite came 60 se situe dans la position passive, la première extrémité 64 de la portion incurvée 66 soit en contact sur la pièce support 23, et inversement, lorsque la came 60 se situe dans sa position active, la seconde extrémité 68 de la portion incurvée 66 assure un dégagement de celle-ci vis-à-vis de l'extrémité inférieure 62 de la pièce support 23, autorisant alors l'élément poussoir 41 à agir sur ladite pièce support 23. Selon ce mode de conception, la came 60 dispose de manière préférentielle et non limitative d'un élément de rappel permettant de pivoter ladite came 60 vers sa position passive lorsque le dispositif d'actionnement est relâché et que le patineur cesse d'agir avec le talon sur l'élément poussoir 41. Le principe de fonctionnement est le suivant : lorsque le patineur relâche le dispositif d'actionnement, autorisant la came 60 à revenir dans sa position initiale passive, l'élément poussoir 41 reste en butée sur la pièce support 23 tant que le patineur maintient une poussée sur le plateau 45 de l'élément poussoir 41 , la came 60 restant dans ce cas en position active, bien que le dispositif d'actionnement soit relâché ; le galet 21a reste par conséquent en contact avec les roues 5a, 7a malgré le relâchement du dispositif d'actionnement. Lorsque le patineur relâche ensuite le plateau 45 de l'élément poussoir 41 , celui-ci revient alors en position initiale sous l'effet du système de rappel 49 dudit élément poussoir ; le corps 47 est alors escamoté à l'intérieur de la platine et se dégage par conséquent de la pièce support 23, ce qui autorise la came 60 à revenir dans sa position passive sous l'action du système de rappel.According to a preferred design of the braking system 9, the cam illustrated in FIG. 5 is pivotally mounted relative to the plate 11 along a transverse pivot axis 58, parallel to that of the axis of rotation 12 of the wheels 5a, 7a. This cam 60 is preferably disposed below the support member 23 and is arranged to bear on the lower end 62 thereof, for example at the axis of rotation 24 of the braking roller 21a. The cam 60 is arranged to pivot from a passive position to an active position, or vice versa. When the actuating device is released, the cam 60 is supported on the lower end 62 of the support piece 23, while preventing it from sliding vertically downwards under a possible force exerted by the skater with the heel which tends to translate downwardly the pusher element 41 resting on the upper end of the support part 23. Conversely, when the actuating device is engaged, the latter causes the pivoting of the cam 60 which passes through the active position according to which said cam 60 is disengaged with respect to the lower end 62 of the support piece 23, then allowing it to translate downwards when a thrust is exerted by the heel of the skater on the plate 45 of the pusher element 41 which translates downwards by bearing on the upper end of the support piece 23, the latter then sliding downwards, which makes it possible to bring the roller into contact with the wheels 5a, 5b. As illustrated in FIG. 5, the cam 60, according to this embodiment, comprises a curved shape arranged so that, when said cam 60 is in the passive position, the first end 64 of the curved portion 66 is in contact. on the support member 23, and conversely, when the cam 60 is in its active position, the second end 68 of the curved portion 66 provides a clearance thereof vis-à-vis the lower end 62 of the workpiece support 23, then allowing the pusher element 41 to act on said support member 23. According to this design, the cam 60 preferably has and not limited to a biasing element for pivoting said cam 60 to its passive position when the actuating device is released and the skater stops working with the heel on the pusher element 41. The operating principle is as follows: when the skater releases the actuating device, allowing the cam 60 to return to its initial passive position, the pusher element 41 remains in abutment on the support piece 23 as long as the skater maintains a thrust on the plate 45 of the pusher element 41, the cam 60 remaining in this case in the active position, although the actuating device is released; the roller 21a therefore remains in contact with the wheels 5a, 7a despite the release of the actuating device. When the skater then releases the plate 45 of the pusher element 41, it then returns to its initial position under the effect of the return system 49 of said pusher element; the body 47 is then retracted inside the plate and therefore emerges from the support part 23, which allows the cam 60 to return to its passive position under the action of the return system.
La pièce support 23 est agencée pour recevoir de manière directe ou indirecte l'élément poussoir. En effet, lorsque la came 27 mise en œuvre est telle qu'illustrée aux figures 1 à 4, l'élément poussoir 41 agit de manière indirecte sur l'extrémité supérieure 44 de la pièce support 23, par le biais de la lamelle flexible 39 de la came 27.The support part 23 is arranged to receive directly or indirectly the pusher element. Indeed, when the cam 27 implemented is as illustrated in Figures 1 to 4, the pusher element 41 acts indirectly on the upper end 44 of the support part 23, through the flexible strip 39 of the cam 27.
Lorsque la came 60 mise en œuvre est telle qu'illustrée sur la figure 5, celle-ci agissant sur l'extrémité inférieure 62 de la pièce support 23, ledit élément support dispose, par exemple, à son extrémité supérieure d'une surface d'appui agencée pour recevoir de manière directe l'extrémité inférieure 70 du corps vertical 47 de l'élément poussoir. Toutefois, il est possible de concevoir l'élément poussoir 41 et la pièce support 23 en une seule pièce selon ce second mode de conception, du fait que lesdits éléments sont en contact direct. Dans ce cas, le corps vertical 47 peut être constitué directement par la pièce support 23, tel qu'illustré en figure 5.When the cam 60 implemented is as shown in Figure 5, the latter acting on the lower end 62 of the support member 23, said support member has, for example, at its upper end a surface of d support arranged to directly receive the lower end 70 of the vertical body 47 of the pusher element. However, it is possible to design the pusher element 41 and the support piece 23 in one piece according to this second design mode, because said elements are in direct contact. In this case, the vertical body 47 can be constituted directly by the support piece 23, as illustrated in FIG.
En outre, il est possible de prévoir un élément de rappel sur la pièce support 23, tel que par exemple un ressort agencé au niveau de la liaison en translation verticale de ladite pièce support 23 avec la platine 11. Cet élément de rappel est agencé pour permettre la translation verticale vers le haut de la pièce support 23 permettant de dégager l'élément de freinage 21 de la roue 5a, 7a lorsque le poussoir 41 cesse d'agir sur l'extrémité supérieure 44 de ladite pièce support 23 et que la came 27 est déplacée en position passive. Cet élément de rappel reste toutefois optionnel ; en effet, lorsque le patineur cesse d'exercer une poussée sur l'élément poussoir 41 , celui-ci cessant alors d'agir sur la pièce support 23, et que la came 27 se situe en position passive, le galet 21a tend à se dégager naturellement vers le haut vis-à-vis des roues 5a, 7a. II est possible d'envisager une variante de conception du dispositif d'actionnement, notamment mise en œuvre lorsque l'élément chaussant est constitué d'une chaussure agencée au-dessus de la platine, ladite chaussure comprenant en outre une semelle fixe vis-à-vis de la platine sur toute la partie arrière, et restant libre vis-à-vis de son extrémité avant, au niveau des orteils, de manière à conserver une liberté de mouvements de la semelle au niveau de son extrémité avant. Le dispositif d'actionnement est alors constitué, selon ce mode de conception, d'une pièce de liaison agencée sous l'extrémité avant de la semelle, cette pièce de liaison étant connectée à la came 27 par l'intermédiaire de l'élément de liaison 29 qui, selon ce cas, est disposé sous la platine 11 en s'étendant longitudinalement vers l'avant de manière à connecter ladite pièce de liaison et la came 27. Ainsi, lorsque le patineur exerce une action avec les orteils pour soulever l'extrémité avant de la semelle, la pièce de liaison tend à se décaler vers le haut et à entraîner la came 27 par le biais de l'élément de liaison 29, ladite came se déplaçant alors dans sa position active.In addition, it is possible to provide a return element on the support member 23, such as for example a spring arranged at the vertical translation connection of said support member 23 with the plate 11. This return element is arranged to allow translation vertical upwards of the support member 23 to disengage the braking member 21 of the wheel 5a, 7a when the pusher 41 stops acting on the upper end 44 of said support member 23 and the cam 27 is moved in passive position. This reminder element remains optional; in fact, when the skater stops exerting a thrust on the pusher element 41, the latter then ceases to act on the support piece 23, and that the cam 27 is in the passive position, the roller 21a tends to naturally clear upwards with respect to the wheels 5a, 7a. It is possible to envisage a variant of the design of the actuating device, in particular implemented when the footwear element consists of a shoe arranged above the plate, said shoe further comprising a fixed soleplate screw-to -vis the plate on the entire rear part, and remaining free vis-à-vis its front end at the toes, so as to maintain freedom of movement of the sole at its front end. The actuating device is then constituted, according to this design, a connecting piece arranged under the front end of the sole, this connecting piece being connected to the cam 27 via the element of link 29 which, in this case, is arranged under the plate 11 extending longitudinally forwards so as to connect said connecting piece and the cam 27. Thus, when the skater exerts an action with the toes to lift the the front end of the sole, the connecting piece tends to shift upwards and drive the cam 27 through the connecting member 29, said cam then moving into its active position.
La platine 11 est agencée pour recevoir les éléments du système de freinage 9 et dispose, en outre, de logements pour la réception des roues 5a, 7a, 8a , 10a du roller, lorsque celui-ci est constitué de quatre roues en ligne tel qu'illustré sur les figures 1 à 5. The plate 11 is arranged to receive the elements of the braking system 9 and has, in addition, housing for the reception of the wheels 5a, 7a, 8a, 10a of the roller, when it consists of four wheels in line such that illustrated in Figures 1 to 5.
