Title (EN) BICYCLE
(FR) BICYCLETTE
Abstract: front page image
(EN)The bicycle of a light type comprises a frame (1) carried by two wheels (2, resp. 3). The rear wheel may be driven by handles (5) and, preferably, by a free wheel mechanism arranged into the hub (8) of the wheel. The bicycle is deprived of a train driving mechanism and of a construction between the front wheel (2) and the rear wheel (3). This arrangement allows a decrease of the effort exerted on the pedals (6) and a healthier position of the body of the user. The shaft which carries the handles (5) traverses the hub (8) of the rear wheel. It is connected therein by a transmission (17, resp. 47, resp. 50) presenting at least a gear change. Said shaft (7) is supported by two bearing (12, resp. 13) extending at each side of the hub (8). By means of this bearing, the rear wheel (3) is connected by a screw fixing device to the frame (1), independently of the shaft (7). The saddle (10) is positioned above the rear hub (8) and carried by a vertical bar (9) of the frame.
(FR)La bicyclette, de type leger, comprend un cadre (1) porte par deux roues (2, resp. 3). La roue arriere peut etre entrainee par des manivelles (5) et, de preference, par un mecanisme a roue libre menage dans le moyeu (8) de la roue. La bicyclette est depourvue de mecanisme d"entrainement a chaine et de construction entre les roues avant (2) et arriere (3). Cette disposition permet une diminution de l"effort exerce sur les pedales (6) et une position plus saine du corps de l"usager. L"arbre qui porte les manivelles (5) traverse le moyeu (8) de la roue arriere. Il y est relie par une transmission (17, resp. 47, resp. 50) presentant au moins un changement de vitesse. Ledit arbre (7) est maintenu par deux paliers (12, resp. 13) debordant de chaque cote du moyen (8). Au moyen de ces paliers, la roue arriere (3) est reliee par une fixation a vis au cadre (1), independamment de l"arbre (7). La selle (10) est placee au-dessus du moyeu arriere (8) et porte par une barre verticale (9) du cadre.
