Abstract
Description
L'objet de l'invention concerne un dispositif de guidon de cycle fonctionnel à positions variables avec poignées de freins incorporées. The object of the invention relates to a functional cycle handlebar device with variable positions with incorporated brake handles.
I1 est destiné à permettre à l'usager une amélioration dans la souplesse et la rapidité de la transmission du freinage rendu plus efficace avec diminution de l'effort, tout en assurant une possibilité de modification instantanée de position de guidon afin d'améliorer le confort du cycliste pour la course, le tourisme ou le rangement. I1 is intended to allow the user an improvement in the flexibility and speed of the braking transmission made more efficient with reduction of the effort, while ensuring the possibility of instantaneous modification of the handlebar position in order to improve comfort. of the cyclist for running, tourism or storage.
Il est connu d'utiliser des guidons transformables en passant de la position dite de course à celle de tourisme, mais il fallait démonter ses moyens de fixations et procéder à une nouvelle fixation ce qui était fastidieux et demandait non seulement un outillage approprié mais encore un temps assez long. It is known to use handlebars transformable from the so-called racing position to that of tourism, but it was necessary to dismantle its fixing means and to carry out a new fixing which was tedious and required not only an appropriate tool but also a quite long time.
Le dispositif suivant l'invention supprime ces inconvénients et permet par un débrayage instantané incorporé à la monture du guidon de lui donner des positions multiples immédiatement appropriées à l'usage envisagé, course, tourisme ou simplement diminution d'encombrement pour le transport, alors que le système de freinage par rotation réduite de la poignée avec une transmission de puissance intégrale avec une course de translation minime mais avec circuit de câble intégralement incorporé dans le guidon ce qui supprime tout risque d'accrochement et diminue l'encombrement. The device according to the invention eliminates these drawbacks and makes it possible, by an instant disengaging incorporated in the handlebar mount, to give it multiple positions immediately suitable for the intended use, racing, tourism or simply a reduction in size for transport, while the brake system by reduced rotation of the handle with an integral power transmission with a minimal translational travel but with cable circuit fully incorporated in the handlebars which eliminates any risk of hooking and reduces bulk.
I1 est constitué par la combinaison d'abord d'un élément d'articulation verrouillable par levier, et ensuite par le montage de la poignée rotative sur une rampe hélicoldale servant de guide à un coulisseau incorporé à la monture tubulaire du guidon et relié au câble de frein. I1 is constituted by the combination first of an articulation element lockable by lever, and then by the mounting of the rotary handle on a helical ramp serving as guide to a slide incorporated in the tubular mount of the handlebar and connected to the cable of brake.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
Les figures 1, 2, 3 représentent le guidon vu en élévation de face, de profil avec parties coupées.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figures 1, 2, 3 show the handlebars seen in front elevation, in profile with cut parts.
Les figures 4, 5, 6 montrent quelques positions pouvant être données aux éléments articulés et instantanément immobilisables. Figures 4, 5, 6 show some positions that can be given to the articulated elements and instantly immobilizable.
La partie fixe du guidon est emmanchée sur le cadre 1 qui immobilise le secteur tubulaire 2. The fixed part of the handlebar is fitted onto the frame 1 which immobilizes the tubular sector 2.
L'extrémité avec courbure 3 est reliée à la monture 2 par l'articulation 4 avec verrouillage au moyen de levier 5. The curved end 3 is connected to the frame 2 by the articulation 4 with locking by means of lever 5.
A l'intérieur de l'élément tubulaire 2 est immobilisé par l'encliquetage 6, un guide tubulaire concentrique 7 dans lequel coulisse le câble de frein 8 intégralement protégé par le guidon dont l'extrémité 9 est reliée à la clavette 10 engagée dans une rampe hélicoldale 11 à pas rapide réalisée à l'extrémité du secteur tubulaire 3. Inside the tubular element 2 is immobilized by the snap 6, a concentric tubular guide 7 in which slides the brake cable 8 fully protected by the handlebar, the end 9 of which is connected to the key 10 engaged in a helical ramp 11 with rapid pitch made at the end of the tubular sector 3.
La poignée 12 recouvre l'extrémité du guidon et se crante sur la clavette ou coulisseau 10 qu'elle entraîne par sa rotation le long de la rampe hélicoïdale 11. The handle 12 covers the end of the handlebar and locks onto the key or slide 10 which it drives by its rotation along the helical ramp 11.
Par ce mouvement à course réduite, le câble 8 tracte le frein où se détend très rapidement sans aucun effort vu la démultiplication obtenue. By this movement with reduced stroke, the cable 8 pulls the brake where it relaxes very quickly without any effort given the reduction obtained.
Par contre, en actionnant le levier on peut déplacer instantanément le secteur 3 dans le sens des flèches A, B. On the other hand, by actuating the lever one can instantly move the sector 3 in the direction of the arrows A, B.
Le guidon prend alors la position horizontale 13, figure 4, on peut relever les branches 14, 15 pour avoir la position tourisme, fig 5. The handlebars then take the horizontal position 13, FIG. 4, the branches 14, 15 can be raised to have the touring position, FIG 5.
La position course, figure 1, est également utilisable. The race position, figure 1, can also be used.
Le repliement total 16, 17, fig 6, est possible ce qui réduit l'encombrement pour le transport ou le rangement du vélo dans un emplacement réduit. Total folding 16, 17, fig 6, is possible which reduces the space required for transporting or storing the bicycle in a reduced location.
Ces manoeuvres de positionnement sont rapides et peuvent s'obtenir même en restant sur le cycle sans utilisation d'un outil quelconque. These positioning maneuvers are rapid and can be obtained even while remaining on the cycle without the use of any tool.
Les assemblages 1, 4 sont réalisables par molettes à serrage à main ou par levier de traction actionnant un excentrique de blocage ou tout autre moyen de verrouillage approprié. The assemblies 1, 4 can be produced by hand-tightening knurls or by traction lever actuating a locking eccentric or any other suitable locking means.
C ' est pourquoi les formes, dimensions et dispositions des divers éléments pourront varier dans la limite des équivalents, comme d ' ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de l'inven- tion qui vient d'être décrite. This is why the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, like the materials used for their manufacture, without changing the general conception of the invention which has just be described.
