Abstract
A reciprocating type driving mechanism for use for a bicycle, baby carriage and wheel chair, which can provide convenience in driving to the user and which comprises: a front and rear wheels W1 and W2; a gear box B; a driving and driven gears 20 and 30 and a side gear 31 formed integrally with the driven gear 30; driving members 40 each comprising three links 41, 42 and 43; a pinion 50 adapted for alternate operation of the driving members 40; a head gear 60 in meshed connection with the side gear 31; an intermediate gear 70 positioned below the head gear 60; a relaying gear 81 in meshed connection with the intermediate gear 70; an output gear 82 provided at the bottom part of the driving axle 80 for transmitting the torque; and a hub gear 90 in meshed connection with the output gear 82 (FIG. 1).
Claims5
A reciprocating driving mechanism comprising:
- a front and rear wheels (W1, W2) provided in the front and rear parts of a car body (10);
- a gear box (B) provided on a head pipe (11) of the car body (10);
- a driving and driven gears (20, 30) in meshed engagement and a side gear (31) formed integrally with the driven gear (30), those gears being built in the gear box (B);
- driving members (40) each comprising three links (41, 42, 43) for rotating the driving gear (20) only in the advancing direction through a first set of unidirectional clutches (C1), the driving members being provided on the both sides of the car body (10);
- a pinion (50) in meshed connection with the racks (42a) formed on the second links (42) and adapted for alternate operation of the driving members (40);
- a head gear (60) in meshed connection with the side gear (31) and provided on a lower part of the head pipe (11) through a bearing (61);
- an intermediate gear (70) provided through a second unidirectional clutch (C2), the intermediate gear being positioned below the head gear (60);
- a relaying gear (81) in meshed connection with the intermediate gear (70) and provided at the top part of a driving axle (80), the driving axle passing through a hook (13) of a steering axle (12) and being fitted in the head pipe (11);
- an output gear (82) provided at the bottom part of the driving axle (80) for transmitting the torque;
- and a hub gear (90) in meshed connection with the output gear (82) and attached to the hub (H) of the front wheel (W1).
