Abstract
Description
La présente invention concerne une direction de vélos à câbles. Elle concerne tous types de vélos. The present invention relates to a bicycle steering cable. It concerns all types of bicycles.
La direction des vélos est constituée d'un guidon, rigidement attaché à un axe de direction et commandant en rotation une fourche qui supporte la roue avant du vélo. The direction of the bikes consists of a handlebar rigidly attached to a steering shaft and rotating a fork that supports the front wheel of the bike.
Cette disposition réduit la flexibilité de positionnent du cycliste sur le vélo. Elle implique en particulier des compromis entre le confort et la performance. This arrangement reduces the flexibility of positioning the cyclist on the bike. In particular, it involves compromises between comfort and performance.
Dans le cas de vélos nécessitant une suspension de la roue avant, elle implique un couplage des fonctions de direction et suspension, qui résulte en un montage complexe des éléments de suspension. In the case of bicycles requiring suspension of the front wheel, it involves a coupling of the steering and suspension functions, which results in a complex assembly of the suspension elements.
L'invention permet de remédier à ces inconvénients. Elle consiste à transmettre, par l'intermédiaire de câbles, le contrôle de la direction entre un moyen de contrôle (guidon ou volant) et la fourche elle-même. Ce moyen de contrôle est lui-même monté sur une colonne de direction. The invention overcomes these disadvantages. It consists in transmitting, via cables, the control of the steering between a control means (handlebar or steering wheel) and the fork itself. This control means is itself mounted on a steering column.
La colonne de direction comprend un réglage de son inclinaison et de sa longueur, de 20 façon à optimiser la posture du cycliste et à s'adapter à sa taille. The steering column includes adjustment of its inclination and length, in order to optimize the cyclist's posture and to adapt to his size.
Le réglage de l'inclinaison se fait par rotation autour d'un axe horizontal, situé en bas de la colonne de direction. Cette rotation est ajustée et maintenue par un ensemble de vis-écrou, composé d'une vis solidaire du cadre du vélo et d'un écrou solidaire de la colonne 25 de direction. Adjustment of the inclination is done by rotation around a horizontal axis, located at the bottom of the steering column. This rotation is adjusted and maintained by a set of screw-nut, consisting of a screw secured to the frame of the bike and a nut secured to the steering column 25.
Le réglage de la longueur se fait par coulissement de deux tubes l'un dans l'autre. La position est maintenue par pincement ou serrage au moyen d'une vis. The adjustment of the length is made by sliding two tubes one in the other. The position is held by pinching or tightening by means of a screw.
30 La cinématique de direction par câble permet de découpler les fonctions de direction et de suspension de la roue avant. The cable directional kinematics allows decoupling the steering and suspension functions of the front wheel.
La position de la colonne de direction entre la fourche et la selle permet un appui plus arrière du cycliste, ce qui permet de ne plus utiliser le guidon comme un appui 35 permanent. The position of the steering column between the fork and the saddle allows a further support of the cyclist, which allows to no longer use the handlebars as a permanent support.
Selon des modes particuliers de réalisation : According to particular embodiments:
- La transmission et la fourche peuvent être rigidement attachés au cadre, ou au 40 contraire, peuvent permettre un déplacement relatif pour assurer une fonction de suspension de roue avant. - The transmission and the fork can be rigidly attached to the frame, or on the contrary, can allow relative movement to provide a front wheel suspension function.
- Le réglage de la position du volant ou guidon peut se faire par translation, rotation ou articulations multiples de la colonne de direction. Le moyen de contrôle de la direction pourra être constitué d'un guidon ou d'un volant de forme adéquate. - Adjustment of the position of the steering wheel or handlebar can be done by translation, rotation or multiple articulations of the steering column. The steering control means may consist of a handlebar or a steering wheel of appropriate shape.
La figure 1 en annexe montre la réalisation d'une telle commande à câble.. 45 2934240 -2 La réalisation de cette invention utilise un guidon (1) de forme appropriée, qui pivote autour d'un axe horizontal (2) situé à l'extrémité d'une colonne de direction composée de deux tubes (3) coulissants l'un dans l'autre.. La colonne de direction se règle en hauteur (5) par coulissement des deux tubes (3). Ils sont maintenus en place par une vis de blocage (6). FIG. 1 in the appendix shows the realization of such a cable control. The embodiment of this invention uses a handlebar (1) of appropriate shape, which pivots about a horizontal axis (2) located at a distance of end of a steering column consisting of two tubes (3) sliding in one another .. The steering column is adjusted in height (5) by sliding of the two tubes (3). They are held in place by a locking screw (6).
La colonne de direction est articulée au cadre du vélo par un axe transversal (7), ce qui 10 permet un réglage de sa position dans le sens avant-arrière (5). Elle est maintenue en position par un ensemble vis-écrou (8), la vis étant prisonnière du cadre et l'écrou étant prisonnier de la colonne de direction. The steering column is hinged to the frame of the bicycle by a transverse axis (7), which allows adjustment of its position in the front-rear direction (5). It is held in position by a screw-nut assembly (8), the screw being trapped in the frame and the nut being trapped in the steering column.
Deux câbles (4) sont accrochés au guidon par leur renflement d'extrémité. Ces câbles transmettent la commande de direction à un levier attaché à la fourche de direction (10), sur laquelle ils sont maintenus par une vis de pincement. Two cables (4) are attached to the handlebars by their end bulge. These cables transmit the steering control to a lever attached to the steering fork (10), on which they are held by a pinch screw.
Pour transmettre correctement l'ordre de direction venant du guidon, les câbles doivent 20 se croiser (11). Un dispositif de réglage de tension (9) sur chacun des câbles permet de s'assurer de l'absence de jeux et du réglage du parallélisme entre le guidon et la fourche.To correctly transmit the steering order from the handlebar, the cables must cross (11). A voltage adjustment device (9) on each of the cables makes it possible to ensure that there are no gaps and the parallelism between the handlebar and the fork is adjusted.
25 Le dispositif selon l'invention est particulièrement destiné à l'amélioration du confort de tous types de vélos. 5 15 The device according to the invention is particularly intended to improve the comfort of all types of bicycles. 5 15
