Abstract

The object of the invention is to provide a bicycle frame structure making it possible to increase its speed of use over flat ground and its ease of use on inclines and downhill. According to this invention, from the box of the pedal mechanism to the tyre of the rear wheel, there will be a distance a of approximately 1 cm instead of 6 cm. From the axis of the box of the pedal mechanism to the axis of the front wheel, there will be a distance b of approximately 64 cm instead of 60 cm. From the axis of the box of the pedal mechanism to the ground, there will be a distance c of approximately 24 cm instead of 27 cm. Such a bike is intended for all types of cycling trial and for example for beating the current world record. The minimal distance between the box of the pedal mechanism and the rear tyre could be obtained by an upright, carrying the saddle 3, of the frame 1 having a bend 2 centred on the axis of the rear wheel.

Description

L'objet de l'invention est de proposer une structure de cadre de vélo permettant d'augmenter sa vitesse d'utilisation sur terrain plat et sa facilité d'utilisation en côte et en descente
Selon cette invention et en référence au dessin joint, de la boite du pédalier au pneu de la roue arrière, il y aura une distance (a) de 1 cm environ au lieu de 6 cm, ce qui permettra de monter les côtes plus vite, De l'axe de la boite du pédalier à l'axe de la roue avant, il y aura une distance (b) de 64 cm environ au lieu de 60 cm, ce qui permettra à ce vélo d'être le plus rapide dans les descentes; De l'axe de la boite du pédalier au sol, il y aura une distance (c) d'environ 24 cm au lieu de 27 cm, ce qui permettra d'entre le plus rapide sur le plat.The object of the invention is to provide a bicycle frame structure making it possible to increase its speed of use on flat ground and its ease of use on hills and descents.
According to this invention and with reference to the attached drawing, from the bottom bracket to the tire of the rear wheel, there will be a distance (a) of about 1 cm instead of 6 cm, which will make it possible to climb the hills faster, From the axis of the bottom bracket to the axis of the front wheel, there will be a distance (b) of approximately 64 cm instead of 60 cm, which will allow this bike to be the fastest in the descents; From the axis of the bottom bracket to the ground, there will be a distance (c) of about 24 cm instead of 27 cm, which will allow the fastest on the flat.

Un tel vélo est destiné à tous types d'épreuves cyclistes et par exemple pour battre le record du monde de l'heure. Such a bicycle is intended for all types of cycling events and for example to beat the world record for the hour.

La distance minimale entre boite de pédalier et le pneu arrière pourra être obtenue par un montant, portant la selle (3) > du cadre (1) présentant un cintrage (2) centré sur l'axe de la roue arrière.  The minimum distance between the bottom bracket and the rear tire can be obtained by an upright, carrying the saddle (3)> of the frame (1) having a bend (2) centered on the axis of the rear wheel.
