La présente invention concerne un ensemble de direction pour cycle et, plus particulièrement, un nouveau montage de guidon sur la fourche, au niveau de la douille de direction. The present invention relates to a steering assembly for a cycle and, more particularly, to a new handlebar mounting on the fork, at the level of the steering bushing.
Les guidons aérodynamiques, du type décrit dans le document FR-A-2 549 796, ont une traverse qui se situe, en position normale, devant la douille de direction du cycle. Dans le document précite, le guidon, et en particulier sa traverse, est solidaire du pivot de fourche, au moyen d'une potence positionnée dans une fenêtre aménagée dans la douille de direction. Ce montage complique la fabrication des cadres ; il est principalement utilisé pour les cycles de compétition, haut de gamme. The aerodynamic handlebars, of the type described in document FR-A-2 549 796, have a cross-member which is, in the normal position, in front of the cycle direction bushing. In the aforementioned document, the handlebars, and in particular its cross member, is integral with the fork pivot, by means of a bracket positioned in a window fitted in the steering bush. This assembly complicates the manufacture of the frames; it is mainly used for high-end competition cycles.
La présente invention a pour objet de permettre une adaptation des guidons aérodynamiques sur les cycles comprenant un cadre classique. L'adaptateur selon l'invention présente l'avantage d'offrir de nouvelles possibilités de réglage, en hauteur notamment, selon la morphologie de l'utilisateur. The object of the present invention is to allow adaptation of the aerodynamic handlebars on cycles comprising a conventional frame. The adapter according to the invention has the advantage of offering new possibilities of adjustment, in particular in height, according to the morphology of the user.
L'ensemble de direction selon l'invention comprend des moyens de liaison du guidon au pivot de la fourche, constitués d'un support tendu devant la douille de direction, solidaire de la tete de fourche, a l'une de ses extrémités, et du pivot de fourciie, à son autre extrémité, à la partie superieure. The steering assembly according to the invention comprises means for connecting the handlebar to the pivot of the fork, consisting of a support stretched in front of the steering bushing, integral with the fork head, at one of its ends, and from the fourciie pivot, at its other end, to the upper part.
Selon une disposition préférentielle de l'invention, ce support comprend des moyens qui permettent un réglage de la position verticale du guidon. Ces moyens sont constitues de lumières aménagées dans le support, pour varier, selon les besoins, la position verticale du guidon. According to a preferred arrangement of the invention, this support comprises means which allow adjustment of the vertical position of the handlebars. These means consist of lights arranged in the support, to vary, as necessary, the vertical position of the handlebars.
Toujours selon l'invention, le support est solidaire de ltextrémité supérieure du pivot de fourche, par l'intermediaire d'une potence verrouillable sur ce dernier, et il est solidaire de la tete de fourche, au niveau de l'attache du frein, au moyen d'une patte d'attache en forme de baïonnette, pour permettre le passage dudit frein. Still according to the invention, the support is secured to the upper end of the fork pivot, by means of a lockable stem on the latter, and it is secured to the fork head, at the level of the brake attachment, by means of a bayonet-shaped fastening tab, to allow the passage of said brake.
Selon une autre disposition de l'invention, le support se présente sous la forme d'un tube soudé, à son extrémité supérieure, sur la potence. Ce tube comporte, a l'avant, une ou plusieurs lumières axiales pour le réglage de la position verticale du guidon. According to another arrangement of the invention, the support is in the form of a tube welded at its upper end to the stem. This tube comprises, at the front, one or more axial slots for adjusting the vertical position of the handlebars.
Selon une autre disposition de l'invention, le guidon est solidaire du support par l'intermédiaire d'une potence qui est vissée à travers la paroi du tube, sur un noyau cylindrique interne, mobile dans ce dernier. According to another arrangement of the invention, the handlebar is secured to the support by means of a bracket which is screwed through the wall of the tube, onto an internal cylindrical core, movable in the latter.
L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexes, donnés à titre indicatif, et dans lesquels - la figure 1 est une vue schématique partielle d'un cycle équipe de l'ensemble de direction selon l'invention - la figure 2 est une vue de détail de l'ensemble de direction, avec une coupe du support notamment. The invention will be further detailed with the aid of the following description and of the accompanying drawings, given for information only, and in which - FIG. 1 is a partial schematic view of a team cycle of the steering assembly according to invention - Figure 2 is a detail view of the steering assembly, with a section of the support in particular.
On a représenté, figure 1, la partie avant d'un cycle et en particulier d'une bicyclette. Le cadre 1 comporte une douille de direction 2 dans laquelle est emmanché le pivot, non apparent, de la fourche 3. There is shown, Figure 1, the front part of a cycle and in particular of a bicycle. The frame 1 comprises a steering bush 2 in which the not visible pivot of the fork 3 is fitted.
Le guidon 4 est constitue d'une traverse 5 qui soutient, lateralement, à chacune de ses extremites, des poignées 6 en forme de cornes de vache. Ce guidon 4 est relié à la fourche 3 au moyen d'un support 7 disposé entre la douille de direction 2 et la traverse 5 du guidon. Ce support est relié à la traverse 5 au moyen d'une potence 8 de guidon, en forme de bec de canard, s'apparentant à l'ensemble décrit dans le document précité FR-A-2 549 796. Le support 7 est relié à une potence 9, à sa partie supérieure ; cette potence 9 est une potence de cycle comportant des moyens classiques de verrouillage sur le pivot de la fourche 3. The handlebar 4 is constituted by a cross-member 5 which supports, laterally, at each of its ends, handles 6 in the form of cow horns. This handlebar 4 is connected to the fork 3 by means of a support 7 disposed between the steering bush 2 and the crosspiece 5 of the handlebar. This support is connected to the crossmember 5 by means of a handlebar stem 8, in the shape of a duckbill, similar to the assembly described in the aforementioned document FR-A-2 549 796. The support 7 is connected to a gallows 9, at its upper part; this stem 9 is a cycle stem comprising conventional locking means on the pivot of the fork 3.
A sa partie inférieure, le support 7 est solidaire de la tête de fourche 10 au moyen d'une patte d'attache 11. La patte d'attache 11 est conformee de façon à laisser le passage du système de freinage 12. At its lower part, the support 7 is secured to the fork head 10 by means of an attachment tab 11. The attachment tab 11 is conformed so as to allow passage of the braking system 12.
Cet ensemble de direction est représenté en détail, figure 2, avec une coupe partielle notamment au niveau du support 7. On retrouve, sur cette figure 2, la douille de direction 2 servant au guidage, par des moyens appropriés classiques, du pivot de la fourche 3. This steering assembly is shown in detail, FIG. 2, with a partial section in particular at the level of the support 7. In this FIG. 2, we find the steering bush 2 serving for guiding, by appropriate conventional means, the pivot of the fork 3.
Le pivot de la fourche 3 reçoit, de façon classique, la potence 9 qui est reliée au support 7. Cette potence 9 est solidaire du pivot de fourche par des moyens classiques du genre cone. The pivot of the fork 3 receives, conventionally, the bracket 9 which is connected to the support 7. This bracket 9 is secured to the fork pivot by conventional means of the cone type.
La branche horizontale 9h de la potence 9 est plus courte que dans le cas d'une potence classique. On remarque que sa longueur, à partir de l'axe général 13 de la douille de direction, correspond sensiblement au diamètre de cette douille 2. L'extrémité avant de la branche horizontale 9h est conformee pour etre soudee sur la partie supérieure du support 7. Ce support 7 se présente sous la forme d'un tube dont la longueur est sensiblement supérieure à la longueur de la douille de direction 2. L'axe 14 de ce support 7 est parallèle à l'axe 13 de la douille de direction 2. Le diamètre du tube constituant le support 7 correspond sensiblement au diamètre de la partie 9v de la potence 9, c'est-à-dire la partie qui s'encastre et se verrouille dans le pivot de la fourche 3. The horizontal branch 9h of the bracket 9 is shorter than in the case of a conventional bracket. It is noted that its length, from the general axis 13 of the steering bush, corresponds substantially to the diameter of this bush 2. The front end of the horizontal branch 9h is conformed to be welded to the upper part of the support 7 This support 7 is in the form of a tube, the length of which is substantially greater than the length of the steering bush 2. The axis 14 of this support 7 is parallel to the axis 13 of the steering bush 2 The diameter of the tube constituting the support 7 corresponds substantially to the diameter of the part 9v of the stem 9, that is to say the part which fits and locks in the pivot of the fork 3.
Ce support 7 se positionne devant la douille de direction 2, et il se présente d'une façon parallèle à cette douille. This support 7 is positioned in front of the steering socket 2, and it is presented in a parallel manner to this socket.
A sa partie inférieure, le support 7 est solidaire de la tete de fourche 10 au moyen d'une patte d'attache 11. La patte d'attache 11 est en forme de baïonnette. Elle comporte un alésage 15 qui permet sa fixation sur les moyens d'attache, non représentés, du syteme de freinage 12. Cette patte 11 comporte, a un niveau supérieur, décalé de façon a permettre le passage du système de freinage 12, un second orifice 16 taraudé, pour la mise en place d'une vis 17 qui traverse le support 7 à sa partie inférieure et permet l'immobilisation de ce dernier sur ladite patte d'attache 11. On remarque que le support 7 comporte à sa partie inférieure, traversé par la vis 17, un noyau 18 ajusté à l'intérieur du tube servant de renfort pour eviter son ecrasement.De meme, une rondelle 19 en acier est conformée entre la tete de la vis 17 et le tube 7 constituant le support. At its lower part, the support 7 is secured to the fork head 10 by means of a fastening tab 11. The fastening tab 11 is in the form of a bayonet. It has a bore 15 which allows its attachment to the attachment means, not shown, of the braking system 12. This tab 11 has, at a higher level, offset so as to allow the passage of the braking system 12, a second orifice 16 threaded, for the establishment of a screw 17 which passes through the support 7 at its lower part and allows the immobilization of the latter on said attachment tab 11. It is noted that the support 7 has at its lower part , through which the screw 17 passes, a core 18 fitted inside the tube serving as reinforcement to avoid its crushing. Likewise, a washer 19 made of steel is formed between the head of the screw 17 and the tube 7 constituting the support.
La partie de la patte 11 en contact avec le tube 7, est conformée pour épouser la forme du tube, c'est-a-dire qu'elle est conformée en arc de cercle. The part of the tab 11 in contact with the tube 7 is shaped to match the shape of the tube, that is to say it is shaped in an arc.
Le tube support 7 comporte, sur sa partie avant, disposées axialement selon les génératrices, des lumières 20, 21, 22 qui permettent un réglage de la position du bec 8 servant de potence au guidon 4. Ces lumières permettent un ajustement en hauteur de la position du guidon 4. The support tube 7 has, on its front part, arranged axially along the generatrices, lights 20, 21, 22 which allow an adjustment of the position of the spout 8 serving as a stem on the handlebar 4. These lights allow an adjustment in height of the handlebar position 4.
On a disposé, sur la figure 2, plusieurs lumieres, 20, 21, 22, separées, pour conserver une meilleure rigidité au support 7. On peut cependant prévoir une seule lumiere qui s'étend sur la majeure partie du tube. We have arranged, in Figure 2, several lights, 20, 21, 22, separated, to maintain a better rigidity to the support 7. It is however possible to provide a single light which extends over the major part of the tube.
Le bec de canard 8 est ancré sur le support 7 au moyen de vis 23 et 24 disposées en haut et en bas respectivement. Ces deux vis 23 et 24 cooperent avec un noyau disposé a l'interieur du support 7. Ce noyau est un noyau cylindrique en acier traité anti-rouille. I1 est allégé dans sa partie centrale et comporte des taraudages positionnés de façon à recevoir les vis 23 et 24. The duckbill 8 is anchored on the support 7 by means of screws 23 and 24 arranged at the top and at the bottom respectively. These two screws 23 and 24 cooperate with a core disposed inside the support 7. This core is a cylindrical core made of anti-rust treated steel. I1 is lightened in its central part and includes threads positioned so as to receive the screws 23 and 24.
On remarque que ce noyau 25 comporte, à sa partie supérieure, un filetage qui permet notamment la mise en place de façon temporaire d'une tige filetée non représentée, facilitant le montage du bec de canard 8 sur le support 7 et en particulier la mise en place et le serrage des vis 23 et 24 sur le noyau 25. Note that this core 25 has, at its upper part, a thread which allows in particular the temporary establishment of a threaded rod not shown, facilitating the mounting of the duckbill 8 on the support 7 and in particular the setting in place and tightening the screws 23 and 24 on the core 25.
Le noyau 25 peut également consister en un tube de plus faible épaisseur, comportant, a l'intérieur, des écrous soudés qui cooperent avec les vis 23 et 24. The core 25 can also consist of a tube of smaller thickness, comprising, on the inside, welded nuts which cooperate with the screws 23 and 24.
Le support 7 comporte a sa partie supérieure un bouchon 26 en matériau plastique ou autre. The support 7 has at its upper part a plug 26 of plastic or other material.
