Human powered drive-mechanism with versatile driving modes

A frame (12) supporting two oscillatably movable members (16R) and (16L) for arms, and two reciprocally movable members (18R) and (18L) for feet. Cables (36) going off in pairs from each of the movable members in opposing directions, redirected by pulleys (34) toward and connected to rotatable members (14). Rotatable members (14) are coaxially connected with a sprocket wheel (42), and are also interconnected by additional cables (31) via pulleys (30) that are held back by springs (40), so as to cause one of a pair of rotatable members (14) to freely ratchet backwards while another one is turning forward. Sprocket wheel (42) is connected with a sprocket chain (44) to a vehicle propelling member (46). Handles (22R) and (22L) are connected with sleeved cables (26) to the topmost parts of movable members (16R) and (16L), and sleeved cables (26) connected at their other ends through a sleeved cable harness (282) to a steering pulley (28), that in turn is solidly connected to vehicle steering member (13). Each one of the movable members are connected to two of cables (36) and two of rotatable members (14) as described above forming individual power trains with two directional power stroke for each one of the movable members. Thus, collectively providing for versatile driving modes where each one of the movable members can be operated individually.
