Description

DISPOSITIF PERMETTANT DE MODIFIER LA POSITION
D'UN CYCLISTE TOUT EN ROULANT
La présente invention a pour objet un dispositif permettant de modifier la position d ' un cycliste tout en roulant.DEVICE FOR MODIFYING THE POSITION
OF A CYCLIST WHILE RIDING
The present invention relates to a device for changing the position of a cyclist while riding.

Il est destiné à l'équipement des bicyclettes aussi bien de compétition que d'usage courant. It is intended for equipping bicycles for both competition and everyday use.

Un changement important dans la position du cycliste en roulant, ne peut s'opérer qu'à partir du guidon et de la selle. Actuellement seul un dispositif de déplacement avant-arrière de la selle est proposé, principalement utilisé en triatlon ( SEQi--St?lfitty )). Les guidons offrent plusieurs possibilités de préhension, dont celle avancée, avec les coudes en appui pour un meilleur aérodynamisme. A significant change in the position of the cyclist while riding can only be made from the handlebars and the saddle. Currently only a front-rear saddle movement device is proposed, mainly used in triatlon (SEQi - St? Lfitty)). The handlebars offer several gripping possibilities, including that advanced, with the elbows in support for better aerodynamics.

L'inconvénient majeur de cette position est que la partie conventionnelle du guidon n'est plus utilisée, et offre une résistance à la pénétration dans l'air, et surtout le cycliste ne dispose plus des commandes de frein qui sont en général placées sur la partie citée plus haut. The major drawback of this position is that the conventional part of the handlebars is no longer used, and offers resistance to air penetration, and above all the cyclist no longer has the brake controls which are generally placed on the part cited above.

Le dispositif suivant la présente invention supprime tous ces inconvénients. En effet, il permet d'une part, d'obtenir une meilleure pénétration dans 1' air grace à 1 1allongement du guidon. en position avancée, tout en conservant une parfaite sécurité dans cette position, d' autre part, grâce au déplacement simultané du guidon et de la selle, de conserver la possibilité de retrouver un cycle classique adapté entre autres aux gravissements des- côtes, tout en assurant une optimisation des deux positions. The device according to the present invention eliminates all these drawbacks. Indeed, it allows on the one hand, to obtain a better penetration in 1 air thanks to 1 elongation of the handlebars. in the advanced position, while maintaining perfect safety in this position, on the other hand, thanks to the simultaneous movement of the handlebars and the saddle, of retaining the possibility of finding a classic cycle adapted inter alia to the climbs of the ribs, ensuring an optimization of the two positions.

Il est constitué par la combinaison d'un guidon articulé, dont les poignées sont portées par deux parallélogrammes déformables situés dans un plan sensiblement horizontal, et d'un support de selle formé d'un parallélogramme déformable situé dans un plan vertical, de telle manière que les poignées du guidon, ainsi que la selle puissent adopter une position normale ou une position avancée, les mouvements ayant lieu simultanément grâce à un système de liaison pouvant être verrouillé ou déverrouillé en roulant par le cycliste. It consists of the combination of an articulated handlebar, the handles of which are carried by two deformable parallelograms located in a substantially horizontal plane, and a saddle support formed by a deformable parallelogram located in a vertical plane, in such a way that the handlebars of the handlebars, as well as the saddle can adopt a normal position or an advanced position, the movements taking place simultaneously thanks to a connection system that can be locked or unlocked while riding by the cyclist.

La figure 2 est le schéma de principe du système de liaison verrouillable entre guidon et selle. Figure 2 is the block diagram of the lockable link system between handlebars and saddle.

La figure 3 est une vue agrandie du guidon, vu de dessus, montrant en traits continus la position normale, et en traits mixtes la position avancée. Figure 3 is an enlarged view of the handlebars, seen from above, showing in solid lines the normal position, and in phantom in the advanced position.

La figure 4 étant une vue agrandie du support de selle, vu de côté. Figure 4 being an enlarged view of the saddle support, seen from the side.

Le dispositif, figures 1 à 4, est constitué d'un guidon articulé 1 et d'un support de selle 2 également articulé, dont les mouvements sont synchronisés par un système hydraulique de liaison représenté schématiquement sur la figure 2. The device, FIGS. 1 to 4, consists of an articulated handlebar 1 and a saddle support 2, also articulated, whose movements are synchronized by a hydraulic connection system shown diagrammatically in FIG. 2.

Chaque poignée 3 du guidon articulé 1 est reliée à une platine centrale 4 par un bras 5 et une biellette 6 formant, avec le support de poignée 7 et ladite platine centrale, un parallélogramme déformable situé sensiblement dans un plan horizontal. Lorsque les poignées 3 sont poussées vers l'avant, les bras 5, entraînent par l'intermédiaire de secteurs dentés 7 dont ils sont pourvus à leur extrémité, une crémaillère 8 coulissant d' avant en arrière dans un guide solidaire de la platine centrale 5, ladite crémaillère entraînant à son tour la tige d ' un vérin de guidon 9 hydraulique. Each handle 3 of the articulated handlebar 1 is connected to a central plate 4 by an arm 5 and a link 6 forming, with the handle support 7 and said central plate, a deformable parallelogram situated substantially in a horizontal plane. When the handles 3 are pushed forward, the arms 5, drive through toothed sectors 7 with which they are provided at their end, a rack 8 sliding from front to back in a guide secured to the central plate 5 , said rack in turn driving the rod of a hydraulic handlebar cylinder 9.

Les supports de poignées 7 permettent le réglage en longueur de celles-ci en vue de les ajuster à la morphologie de chaque cycliste, et sont équipés de repose-coudes 10 pour la position avancée. The handle supports 7 allow the length of these to be adjusted in order to adjust them to the morphology of each cyclist, and are equipped with elbow rests 10 for the advanced position.

Le support de selle 2 est formé d'une biellette avant 11 et d'une biellette arrière 12, articulées d'une part sur une embase 13 fixée au cadre de la bicyclette, et d'autre part à un élément porte-selle 14, l'ensemble formant un parallélogramme déformable situé dans un plan vertical. Un vérin 15, également articulé sur l'embase 13 et l'élément porte-selle 14, permet à la selle de passer de la position normale à la position avancée ou vice-versa en même temps que les poignées du guidon. The saddle support 2 is formed by a front link 11 and a rear link 12, articulated on the one hand on a base 13 fixed to the frame of the bicycle, and on the other hand to a saddle-carrying element 14, the assembly forming a deformable parallelogram located in a vertical plane. A jack 15, also articulated on the base 13 and the saddle-carrying element 14, allows the saddle to pass from the normal position to the advanced position or vice versa at the same time as the handlebars.

L'une des biellettes du support de selle 2 (ici la biellette arrière 12) est réglable en longueur à l'arrêt, pour permettre d ' obtenir des variantes de positions finales. One of the links of the saddle support 2 (here the rear link 12) is adjustable in length when stationary, to allow variants of final positions to be obtained.

Aussi bien pour le guidon, l'amplitude des mouvements est limitée par les vérins eux-mêmes jouant le rôle de butées de déplacement. As well for the handlebars, the amplitude of the movements is limited by the jacks themselves playing the role of displacement stops.

Le système de liaison hydraulique est constitué par un circuit double 16, 17, reliant les pistons de guidon 9 et de selle 15, qui sont tous deux à double effet, en leur imposant des déplacements simultanés. Un distributeur 18, pouvant être actionné par le cycliste grâce à un câble 19, permet de bloquer les mouvements en interrompant le circuit hydraulique. Le changement de position s'opère, sans cesser de rouler, en déverrouillant le distributeur 18 par l'action d'une manette (non représentée) fixée sur le guidon ou le cadre, et en provoquant le déplacement simultané des poignées du guidon et de la selle par un balancement d' avant en arrière ou d ' arrière en avant. The hydraulic connection system consists of a double circuit 16, 17, connecting the handlebar 9 and saddle 15 pistons, which are both double-acting, by imposing simultaneous displacements on them. A distributor 18, which can be activated by the cyclist using a cable 19, makes it possible to block movements by interrupting the hydraulic circuit. The change of position takes place, without ceasing to roll, by unlocking the distributor 18 by the action of a lever (not shown) fixed on the handlebars or the frame, and by causing the simultaneous displacement of the handles of the handlebars and of the saddle by rocking back and forth or back and forth.

La liaison entre les deux organes articulés peut être assurée par tout autre moyen permettant d'obtenir le même résultat, par exemple des câbles, gainés ou non. The connection between the two articulated members can be ensured by any other means making it possible to obtain the same result, for example cables, sheathed or not.

Le positionnement des divers éléments constitutifs donne à 1 'objet de 1 'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
