Abstract

A bicycle handlebar, especially for a racing cycle, is made from a curved tube (1). The tube has two diametrically-opposite recesses running along its sides from end to end, made to contain brake (4) and gear-change (5) cables. The recesses can also be used with specially-shaped handle-grips which have lengthwise projections on the inside and are designed to prevent twisting. The tube can be produced by drawing, followed by bending to the required shape. ADVANTAGE - Reduced aerodynamic drag. (5pp Dwg.No.3/3)

Description

La présente invention se rapporte aux guidons de bicyclettes, en particulier pour bicyclettes de course, composés d'un élément tubulaire cintré. The present invention relates to bicycle handlebars, in particular for racing bicycles, composed of a curved tubular element.

Les guidons selon l'invention sont caractérisés en ce que l'élément tubulaire présente au moins une première rainure axiale qui s'étend longitudinalement d'une extrémité de l'élément à l'autre et est adaptée pour servir de logement pour recevoir un câble de commande. The handlebars according to the invention are characterized in that the tubular element has at least a first axial groove which extends longitudinally from one end of the element to the other and is adapted to serve as a housing for receiving a cable control.

L'élément tubulaire constituant le guidon possS- de de préférence une deuxième rainure axiale qui présente des caractéristiques analogues celles de la première rainure et qui est radialement à ltopposé de celle-ci;
En particulier, les rainures sont destinées à jouer le rôle de logements pour recevoir le câble de commande du frein et/ou le câble de commande du changement de vitesse de la bicyclette, et elles ont en outre une importante fonction d'accroissement de la résistance à la flexion des guidons.The tubular element constituting the handlebars preferably has a second axial groove which has characteristics similar to those of the first groove and which is radially opposite it;
In particular, the grooves are intended to act as housings for receiving the brake control cable and / or the speed change control cable of the bicycle, and they also have an important function of increasing the resistance. bending of the handlebars.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la description qui va suivre d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels
la figure 1 est une vue partielle en coupe d'un guidon selon l'invention ;
la figure 2 est une coupe prise selon la ligne
II-II de la figure 1 et
la figure 3 est une coupe prise selon la ligne
III-III de la figure 1.Other characteristics and advantages of the invention will be better understood from the description which follows of an exemplary embodiment and with reference to the appended drawings in which
Figure 1 is a partial sectional view of a handlebar according to the invention;
Figure 2 is a section taken along the line
II-II of figure 1 and
Figure 3 is a section taken along the line
III-III of figure 1.

Comme on le peut le voir en se reportant aux dessins, un élément métallique tubulaire qui est recourbé ou cintré selon la forme habituelle pour les bicyclettes de course est désigné par 1. I1 va de soi que les caractéristiques innovatives qui font l'objet de l'invention peuvent être appliquées à des guidons de n'importe quelle configuration. As can be seen by referring to the drawings, a tubular metal element which is curved or bent in the usual form for racing bicycles is designated by 1. It is self-evident that the innovative features which are the subject of the The invention can be applied to handlebars of any configuration.

L'élément tubulaire 1 présente deux rainures axiales 2, 3 qui sont de préférence radialement à l'opposé l'une de l'autre et qui s'étendent d'une extrémité de l'élément tubulaire à l'autre. Les rainures sont destinées à servir de logements pour recevoir des câbles respectifs 4 et 5 destinés à commander les freins et le chanqement de vitesse de la bicyclette. Ces câbles de commande peuvent être positionnés dans leurs logements et maintenus en place par enroulement du ruban adhésif du type communément utilisé pour recouvrir le guidon des bicyclettes de course. The tubular element 1 has two axial grooves 2, 3 which are preferably radially opposite one another and which extend from one end of the tubular element to the other. The grooves are intended to serve as housings for receiving respective cables 4 and 5 intended to control the brakes and the change of speed of the bicycle. These control cables can be positioned in their housings and held in place by winding adhesive tape of the type commonly used to cover the handlebars of racing bicycles.

Ceci a l'davantage de réduire la résistance à l'avancement de la bicyclette qui peut être provoqué par les câbles qui font saillie au-delà du profil du guidon. This has the advantage of reducing the resistance to the advance of the bicycle which can be caused by the cables which protrude beyond the profile of the handlebars.

Sur les dessins, un manchon raidisseur est indi -qué en 8 pour s'accoupler à un oeil porté par la potence ou colonne de direction, non représentée, de la bicyclette. Le guidon selon l'invention peut avantageusement être utilisé en-combinaison avec un manchon 6 du type représenté sur la figure 2, qui est muni d'une ou de deux nervures 7, 8 complémentaires des rainures de l'élément tubulaire de manière à établir un accouplement par sûreté de forme entre le manchon et l'élément tubulaire, accouplement qui rend le positionnement et le serrage du manchon oarticulièrement faciles. In the drawings, a stiffening sleeve is indicated at 8 to mate with an eye carried by the stem or steering column, not shown, of the bicycle. The handlebars according to the invention can advantageously be used in combination with a sleeve 6 of the type shown in FIG. 2, which is provided with one or two ribs 7, 8 complementary to the grooves of the tubular element so as to establish a form-safe coupling between the sleeve and the tubular element, a coupling which makes positioning and tightening of the sleeve particularly easy.

Le guidon peut être fabriqué par une simple opération d'étirage de facon à former une ou plusieurs rainures 2, 3, le montage facultafif du manchon 6 et le cintrage de l'élément tubulaire à la forme voulue étant exécutés ensuite. Ces opérations n'entrainent pas un accroissement notable des frais de fabrication. The handlebars can be manufactured by a simple stretching operation so as to form one or more grooves 2, 3, the optional mounting of the sleeve 6 and the bending of the tubular element to the desired shape being then carried out. These operations do not lead to a significant increase in manufacturing costs.

Bien entendu, diverses modifications peuvent être aooortées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple sans sortir d cadre de l'invention.  Of course, various modifications can be made by a person skilled in the art to the device which has just been described only by way of example without departing from the scope of the invention.
