Abstract

The rapid mounting and dismounting of a bicycle rear wheel by engaging the wheel hub axle on the rear fork is accomplished by a movement directed from the rear to the front. A movable hook allows this particular movement when the bicycle, without a chain, is equipped with a conical gearing transmission on the rear wheel. The wheel attachment is constituted by a hook (1) which is movable about a spindle (2). When it encloses the wheel hub axle (4) it is in the form of a clamping collar and is held locked by means of a pin (3) which prevents it from escaping rearwards.

Description

La-présente invention concerne un dispositif en forme de crochet qui, en se refermant à l'extrémité d'une branche de fourche arrière de bicyclette, permet de retenir efficacement l'axe de la roue arrière. The present invention relates to a hook-shaped device which, by closing at the end of a rear fork leg of a bicycle, makes it possible to effectively retain the axis of the rear wheel.

Ce dispositif est apparu nécessaire après la mise au point d'un vélo sans chaîne construit à partir du brevet français numéro 9I I2I56. This device appeared necessary after the development of a chainless bicycle built from French patent number 9I I2I56.

Les dessins annexés illustrent l'invention
La figure I représente. vu du côté gauche, un vélo classique avec une chaîne, sans sa roue arrière. On n'a pas représenté non plus la branche àroite de la fourche arrière pour faciliter la présentation. le sens de la flèche indique que pour monter la roue arrière, il faut engager le moyeu de la roue arrière à l'extrémité de la fourche dans une direction oblique, du bas vers le haut, et de l'avant vers l'arrière. Ce mouvement est possible pour une roue classique équipée d'une chaise. The accompanying drawings illustrate the invention
Figure I shows. seen from the left side, a classic bicycle with a chain, without its rear wheel. We have also not shown the right side of the rear fork to facilitate presentation. the direction of the arrow indicates that to mount the rear wheel, the rear wheel hub must be engaged at the end of the fork in an oblique direction, from bottom to top, and from front to back. This movement is possible for a conventional wheel fitted with a chair.

Pour une roue équipée d'un engrenage cônique, ce mouvement est impossible, car l'engrenage conique monté sur le moyeu de la roue arrière, au côté droit, vient heurter l'engrenage cônique correspondant fixé à demeure sur le côté intérieur de l'extrémité de la branche adroite de la fourche arrière. For a wheel equipped with a bevel gear, this movement is impossible, because the bevel gear mounted on the rear wheel hub, on the right side, strikes the corresponding bevel gear fixed permanently on the inside of the end of the right branch of the rear fork.

la figure 2 représente, vue du côté gauche, située dans le même plan qu'à la figure I, la branche gauche de la fourche arrière du même vélo, mais cette fois avec une transmission par engrenages côniques pour la roue arrière au côté droit. Figure 2 shows, seen from the left side, located in the same plane as in Figure I, the left branch of the rear fork of the same bike, but this time with a bevel gear transmission for the rear wheel on the right side.

Le sens de la flèche indique la meilleure façon d'engager le moyeu de la roue arrière sur la fourche arrière, dans un mouvement de l'arrière vers l'avant.The direction of the arrow indicates the best way to engage the rear wheel hub on the rear fork, in a back-to-front movement.

Le dessin de la fourche arrière sur la figure I montre que l'axe du moyeu de la roue arrière encaisse normalement le poids du cycliste, comme une force s'exerçant du bas vers le haut. Le choc des obstacles rencontrés éventuellement sur la route, qui poussent l'axe du moyeu de l'avant vers l'arrière, est également bien encaissé grace à la forme de l'extrémité de la fourche qui interdit tout déplacement vers l'arrière.  The drawing of the rear fork in Figure I shows that the axis of the rear wheel hub normally collects the weight of the cyclist, as a force exerted from the bottom up. The shock of obstacles encountered possibly on the road, which push the axis of the hub from front to rear, is also well absorbed thanks to the shape of the end of the fork which prevents any movement backwards.

le dessin de la figure 2 montre par contre qu'en cas de choc de l'avant vers l'arrière, l'axe du moyeu risque de s'échapper vers l'arrière
Le même dessin de la figure 2 montre, relevé vers le haut, un crochet (I) mobile autour d'un axe (2), qui se referme grace à une goupille (3).the drawing of FIG. 2 shows on the other hand that in the event of an impact from front to rear, the axis of the hub risks escaping towards the rear
The same drawing in FIG. 2 shows, raised upwards, a hook (I) movable around an axis (2), which closes thanks to a pin (3).

Le dessin de la figure 3 montre que le crochet refermé prend la forme d'un collier cui enserre parfaitement l'axe (4) du moyeu de la roue arrière. L'axe (2) et la goupille (3) sont suffisemment solides pour encaisser les chocs de l'avant vers l'arrière. The drawing of FIG. 3 shows that the closed hook takes the form of a collar which perfectly encloses the axis (4) of the hub of the rear wheel. The axle (2) and the pin (3) are strong enough to absorb shocks from the front to the rear.

Si ce dispositif est brevetable, n'ayant pas d'antériorités, il n'a d'intérêt que si le brevet français no 91 I2I56 (boîte mécanique pour vélo sans chaine) connait un réel succès, car ce dispositif pour monter et démonter rapidement la roue arrière me parait être le plus pratique possible.  If this device is patentable, having no prior art, it is only of interest if French patent No. 91 I2I56 (mechanical gearbox for bicycle without chain) knows a real success, because this device for mounting and dismounting quickly the rear wheel seems to me to be as practical as possible.
