ENSEMBLE DE GUIDON POUR BICYCLETTE. HANDLEBAR ASSEMBLY FOR BICYCLE.
La présente invention concerne un ensemble de guidon pour bicyclette, intégrant les fonctions de potence, de cintre et de poignées de freins et de changement de vitesses. On connaît déjà des guidons de bicyclette, appelés couramment « guidons monoblocs » ou « cintres monoblocs », qui présentent, sur un seul et même produit en carbone ou en aluminium, les fonctions de cintre et de potence. De manière générale, dans les guidons connus de l'art antérieur, y compris les guidons mentionnés ci-dessus ayant les fonctions potence et cintre sur un même produit, les poignées de frein sont fixées au cintre par l'intermédiaire d'un collier de serrage avec une vis de serrage. On a déjà cherché à mieux intégrer les poignées de frein dans la structure du guidon. Ainsi, à titre d'exemple, le document EP 1 245 482 B1 décrit une partie de prise externe d'un guidon de bicyclette, qui comprend une section de montage ayant une première forme transversale et une section de support avec une seconde forme transversale couplée de manière amovible à la section de montage pour former une première section de prise. Ces première et seconde formes transversales ont des bords axiaux longitudinaux de niveau qui sont raccordés ensemble pour former une première surface de prise annulaire de la première section de prise. La section de support est couplée de manière amovible à la section de montage par un agencement de saillie et d'enfoncement. The present invention relates to a bicycle handlebar assembly, incorporating the functions of stem, handlebars and brake and shift handles. Already known bicycle handlebars, commonly called "monobloc handlebars" or "monobloc hangers", which have, on a single product in carbon or aluminum, the functions of hanger and stem. Generally speaking, in the handlebars known from the prior art, including the aforementioned handlebars having the functions stem and hanger on the same product, the brake handles are fixed to the hanger by means of a collar of tightening with a clamping screw. We have already tried to better integrate the brake handles in the handlebar structure. Thus, by way of example, EP 1 245 482 B1 discloses an outer grip portion of a bicycle handlebar, which includes a mounting section having a first transverse shape and a support section with a second coupled transverse shape. removably at the mounting section to form a first grip section. These first and second transverse shapes have longitudinal axial level edges which are connected together to form a first annular engagement surface of the first engagement section. The support section is releasably coupled to the mounting section by a projection and depression arrangement.
Le but de la présente invention est de fournir un ensemble de guidon pour bicyclette, qui permette de supprimer la liaison par collier et vis de serrage des poignées des freins sur le cintre. Un autre but de la présente invention est de fournir 35 un tel ensemble de guidon, qui présente de hautes qualités ergonomiques. The object of the present invention is to provide a bicycle handlebar assembly, which makes it possible to eliminate the connection by collar and clamping screw of the brake handles on the hanger. Another object of the present invention is to provide such a handlebar assembly which has high ergonomic qualities.
Enfin, c'est également un but de la présente invention de fournir un tel ensemble de guidon, qui soit, de manière générale, simple, stable, et économique, notamment par son mode de fabrication.

Pour parvenir à ces buts, la présente invention a pour objet un ensemble de guidon pour bicyclette, qui comporte une potence et un cintre réalisés « monobloc » et dans lequel les corps de poignée des freins sont également réalisés « monobloc » avec la potence et le cintre, les commandes des freins et de changement des vitesses étant ensuite assemblées directement sur lesdits corps de poignée des freins intégrés au cintre. Selon le mode de réalisation préféré de l'invention, la potence, le cintre et les corps de poignée des freins sont obtenus par une seule et même opération de moulage. Selon le mode de réalisation préféré de l'invention également, l'ensemble de guidon est réalisé en carbone. De préférence, le cintre est de forme tubulaire, de manière à permettre la circulation à l'intérieur du cintre des câbles de commande des freins et de changement de vitesses. De préférence également, chaque corps de poignée de frein comporte un logement apte à recevoir un sous-ensemble intégrant les commandes des freins et de changement de vitesses. Les sous-ensembles de commande des freins et de changement de vitesses sont assemblés, de préférence, par vissage sur les corps de poignée des freins. De préférence, les corps de poignée des freins font saillie sur les parties latérales courbes du cintre, plus particulièrement dans la section médiane sensiblement verticale desdites parties latérales courbes du cintre. Selon une variante correspondant à un type particulier de système de freinage monté sur le guidon, l'ensemble de guidon peut comporter au moins une lumière à l'intérieur du cintre. To achieve these aims, the present invention relates to a handlebar assembly for a bicycle, which comprises a stem and a hanger made "monobloc" and wherein the brake handle bodies are also made "monobloc" with the stem and the hanger, the brake and shift controls being then assembled directly on said handle bodies of the brakes integrated in the hanger. According to the preferred embodiment of the invention, the stem, the handlebars and the handle bodies of the brakes are obtained by a single molding operation. According to the preferred embodiment of the invention also, the handlebar assembly is made of carbon. Preferably, the hanger is of tubular shape, so as to allow the circulation inside the hanger brake control cables and shifting. Also preferably, each brake handle body comprises a housing adapted to receive a subassembly incorporating the controls of the brakes and shifting. The brake and shift control sub-assemblies are preferably assembled by screwing onto the brake handle bodies. Preferably, the handle bodies of the brakes protrude from the curved lateral parts of the hanger, more particularly in the substantially vertical median section of said curved lateral portions of the hanger. According to a variant corresponding to a particular type of brake system mounted on the handlebar, the handlebar assembly may comprise at least one light inside the handlebar.
De manière avantageuse, des trous peuvent être prévus dans le cintre, de façon que tous les câbles des commandes des freins et de changement de vitesses puissent passer à l'intérieur du cintre. Advantageously, holes may be provided in the hanger, so that all cables of the brake and shift controls can pass inside the hanger.
La présente invention a également pour objet une bicyclette, qui comporte un ensemble de guidon conforme à celui décrit ci-dessus dans ses grandes lignes. D'autres buts, avantages et caractéristiques de l'invention apparaîtront dans la description qui suit d'un exemple de réalisation, non limitatif de l'objet et de la portée de la présente demande de brevet, accompagnée de dessins dans lesquels : - la figure 1 est une vue en perspective, schématique, d'un ensemble de guidon selon la présente invention, et - la figure 2 est une vue en perspective, également schématique, d'un sous-ensemble de commandes des freins et de changement de vitesses positionné en face de son logement prévu dans le corps de poignée de frein de l'ensemble de guidon de la figure 1. The present invention also relates to a bicycle, which comprises a handlebar assembly according to that described above in outline. Other objects, advantages and features of the invention will appear in the following description of an example of embodiment, not limiting the object and scope of the present patent application, accompanied by drawings in which: - the FIG. 1 is a schematic perspective view of a handlebar assembly according to the present invention; and FIG. 2 is a perspective view, also schematic, of a subset of brake and shift controls. positioned opposite its housing provided in the brake handle body of the handlebar assembly of Figure 1.
En référence au dessin de la figure 1, on a représenté un ensemble de guidon pour bicyclette, comportant, de manière classique les parties suivantes : - le cintre du guidon, de forme tubulaire, de référence générale 20, qui comprend une partie droite 21 et deux parties latérales courbes 22 et 23 et qui a pour fonction principale d'orienter la roue avant de la bicyclette, et par là même, de contrôler la trajectoire, et - une potence de guidon, de référence 10, ancrée au centre du cintre, qui lie le cintre à la fourche. Referring to the drawing of Figure 1, there is shown a bicycle handlebar assembly, comprising, in a conventional manner the following parts: - the handlebar hanger, tubular, general reference 20, which comprises a straight portion 21 and two curved lateral parts 22 and 23 and whose main function is to orient the front wheel of the bicycle, and thereby to control the trajectory, and - a handlebar stem, reference 10, anchored in the center of the hanger, which links the hanger to the fork.
Selon le principe de la présente invention, la potence 10 et le cintre 20 sont réalisés « monobloc » ainsi que les corps de poignée des freins référencés 32, 33 situés sur les parties courbes 22 et 23 du cintre, respectivement. De préférence, les corps de poignée des freins 32, 33 font saillie sur les parties latérales courbes 22, 23 du cintre, plus particulièrement dans la section médiane sensiblement verticale desdites parties latérales courbes du cintre. Il va de soi que les corps de poignée des freins 32, 33 peuvent être situés différemment sur le cintre, et que le cintre lui-même peut être de forme différente, en particulier moins rond, plus anatomique, plus avancé, etc. L'ensemble de guidon comprenant la potence 10, le cintre 20 et les corps de poignée des freins 32 et 33 forment une seule et même pièce obtenue par une seule et même opération de moulage. A titre d'exemple non limitatif de la portée et de l'objet de la présente invention, l'ensemble de guidon de l'invention peut être réalisé par moulage de carbone. En référence au dessin de la figure 2, chaque corps de poignée de frein 32, 33 comporte un logement 32A, respectivement 33A, apte à recevoir un sous-ensemble de commande de freins et/ou de changement de vitesses, référencé 40 de manière générale. Seul le corps de poignée de frein 32 avec son logement 32A est représenté, le corps de poignée de frein 33 avec son logement 33A étant identique à celui représenté. Les flèches « A » de la figure 2 illustrent le mouvement de mise en place du sous-ensemble de commande de freins et/ou de changement de vitesses 40 dans son logement sur le corps de poignée de freins correspondant. Les sous-ensembles 40 des commandes des freins et de changement de vitesses sont avantageusement assemblés par vissage sur les corps des poignées des freins 32 et 33. Selon le système de freinage utilisé, l'ensemble de guidon peut comporter, en variante, au moins une lumière (non représentée) à l'intérieur du cintre 20. Le cintre 20 est de forme tubulaire. Tous les câbles des freins et de changement de vitesses pourront passer à l'intérieur du cintre 20. A cette fin, des trous (non représentés) peuvent être prévus dans le cintre, de manière connue en soi. According to the principle of the present invention, the stem 10 and the hanger 20 are made "monobloc" and the handle bodies of the brakes referenced 32, 33 located on the curved portions 22 and 23 of the hanger, respectively. Preferably, the handle bodies of the brakes 32, 33 protrude from the curved lateral portions 22, 23 of the hanger, more particularly in the substantially vertical median section of said curved lateral portions of the hanger. It goes without saying that the handle bodies of the brakes 32, 33 may be located differently on the hanger, and that the hanger itself may be of different shape, in particular less round, more anatomical, more advanced, etc. The handlebar assembly comprising the stem 10, the hanger 20 and the handle bodies of the brakes 32 and 33 form a single piece obtained by a single molding operation. As a non-limiting example of the scope and object of the present invention, the handlebar assembly of the invention may be made by carbon molding. Referring to the drawing of Figure 2, each brake handle body 32, 33 comprises a housing 32A, respectively 33A, adapted to receive a brake control subassembly and / or shifting, referenced 40 generally . Only the brake handle body 32 with its housing 32A is shown, the brake handle body 33 with its housing 33A being identical to that shown. The arrows "A" in FIG. 2 illustrate the positioning movement of the brake and / or shift control sub-assembly 40 in its housing on the corresponding brake handle body. The subassemblies 40 of the brake and gearshift controls are advantageously assembled by screwing onto the bodies of the brake handles 32 and 33. Depending on the braking system used, the handlebar assembly may comprise, as a variant, at least a light (not shown) inside the hanger 20. The hanger 20 is tubular. All the cables of the brakes and shifts can pass inside the hanger 20. To this end, holes (not shown) can be provided in the hanger, in a manner known per se.
L'ensemble de guidon décrit ci-dessus présente d'autres avantages que ceux déjà mentionnés précédemment, en particulier les avantages suivants : - il permet de supprimer la liaison mécanique par 5 collier et vis de serrage entre les poignées de frein et le cintre, - il est ergonomique, - il est de conception et de réalisation simples, - il permet un montage simple des mécanismes des 10 freins et de changement des vitesses, - il est robuste, fiable et économique. The handlebar assembly described above has other advantages than those already mentioned above, in particular the following advantages: it makes it possible to eliminate the mechanical connection by collar and clamping screw between the brake handles and the hanger, - it is ergonomic, - it is simple in design and construction, - it allows a simple assembly of the mechanisms of the 10 brakes and shifting, - it is robust, reliable and economical.
