Abstract

The invention relates to bicycle handlebars making it possible to slide them to a variable height. The device comprises a stem which is extended at the front by an inclined tube 2 on which slides a sleeve 5 carrying the fixing collar 4 of the handlebars. This sleeve is locked with the aid of a handle 11 by means of a cone 7 penetrating the orifices 10 of the tube 2 and is maintained in this position by a spring 9. This device is suitable for all bicycles and is intended to give the maximum comfort and efficiency especially for long tours.

Description

La présente invention concerne la pièce de bicyclette nommée -"guidon't elle a pour but de permettre son réglage aisé en hauteur sans descendre de machine - Le guidon actuel dit "de course" présente des inconvénients 10/Une position haute comprimant la poitrine et rendant l'usage des freins trés pénible surtout en longue descente ; elle donne également peu de précision de maneuvre en raison de la position rapprochée des mains.The present invention relates to the bicycle part called - "handlebar 'it aims to allow its easy height adjustment without getting off the machine - The current handlebars called" racing "has drawbacks 10 / A high position compressing the chest and making the use of the brakes very difficult especially on long descents; it also gives little precision of maneuver due to the close position of the hands.

2 / Une position basse inconfortable , les bras étant génés par la
par Lie haute et les freins difficilement accessibles 30/ Une position trés inconfortable des mains vite douloureuses en longs parcours.2 / An uncomfortable low position, the arms being bothered by the
by Lie high and the brakes difficult to access 30 / A very uncomfortable position of quickly sore hands on long journeys.

Le guidon selon l'invention pallie à ces inconvénients en permettant de nombreuses positions différentes en hauteur , facilement obtenues et permettant toutes un usage aisé des freins et une posture écartée des mains, aima la position la plus haute (promenade) est plus haute que la position la plus élevée des guidons fixes - et la position basse , plus basse perme-ttant un effort maximum.The handlebars according to the invention overcomes these drawbacks by allowing many different positions in height, easily obtained and all allowing easy use of the brakes and a posture apart from the hands, like the highest position (ride) is higher than the highest position of the fixed handlebars - and the lower, lower position allows maximum effort.

Les dessins anéxéo comprennent 3 figures representant les éléments du dispositif.The annexed drawings include 3 figures representing the elements of the device.

En figure (I) la potence habituelle du guidon est prolongée par un tube (2) de section rectangulaire et de longueur suffisante pour une inclinaison optimale du corps en fonction de l'effort à fournir par le cycliste . Ce tube est de section rectangulaire pour enlever tout pivotement du guidon pendant la maneuvre d'élèvation ou d'abaissement +
Le guidon (3) "type plat" ou "trial" est fixé par un collier (4) à un manchon (5) coulissant sur le tube (2) ; ce manchon comporte deux épaulements t6) portant l'axe de rotation du dispositif comprenant en partie aval un cône (7) pénétrant dans les orifices (10) du tube fixe (2) , et en partie amont un évidenent (8) correspondant à son symétri que dais le nanchon et recevant un ressort (9) assurant le vérouillade cu cons - ce dispositif à bacsule est assorti d'une poignée à bascule (II) renvoyée par l'avant, permettant la maneuvre sans effort et sans la cher le guidon.In figure (I) the usual stem of the handlebar is extended by a tube (2) of rectangular section and of sufficient length for an optimal inclination of the body according to the effort to be provided by the cyclist. This tube is of rectangular section to remove any pivoting of the handlebar during the raising or lowering maneuver +
The handlebar (3) "flat type" or "trial" is fixed by a collar (4) to a sleeve (5) sliding on the tube (2); this sleeve has two shoulders t6) carrying the axis of rotation of the device comprising partly downstream a cone (7) penetrating into the orifices (10) of the fixed tube (2), and partly upstream an obvious (8) corresponding to its symmetrical that dais the nanchon and receiving a spring (9) ensuring the lock cu cons - this device to bacsule is accompanied by a rocking handle (II) returned by the front, allowing the effortless maneuver and without the expensive handlebars .

Une Première variante consiste à fixer le tube (2) avec pivotement à 45 degré ce qui permet de renvoyer plus aisément la poignée paralléle ment au guidon.A first variant consists in fixing the tube (2) with 45 degree pivoting which makes it easier to return the handle parallel to the handlebar.

Une deuxième variante consiste à remplacer le tube rectangulaire (2) par un tube de section ovale empêchant également le pivotement mais
facilitant le coulissement. A second variant consists in replacing the rectangular tube (2) by an oval section tube also preventing pivoting but
facilitating sliding.

La figure (2) montre en vue latérale le dispositif avec indication du tube en coupe
Enfin, la figure (3) montre la vue de face avec la poignée , le dis positif ainsi décrit peut s'adapter sur toutes les bicyclettes en don nant le maximum de confort et d'efficacité. Figure (2) shows in side view the device with indication of the sectional tube
Finally, Figure (3) shows the front view with the handle, the positive thus described can be adapted on all bicycles giving maximum comfort and efficiency.
