Device for Propelling Vehicles
The system disclosed in this patent application makes it possible to move one or more driving wheels for propelling a vehicle, by actuating two pedals with an alternating linear movement. The system comprises a structure (1) for carrying the remaining components, and pedals (9 and 23) supported on slides (8 and 22) that are moved along two independent guides (7). The movement of the pedals (9 and 23) causes two pulleys (6 and 20) mounted on the axle (14) to rotate, each pulley being linked to the corresponding pedal by a line (5). The torque applied to the axle (14) is in turn transmitted to the axle (15) through another flexible element (4) that interconnects the two toothed wheels (12) and (13), causing the vehicle to move. This system can be used to convert an alternating linear movement into a rotational movement, of human or other origin, in particular for propelling vehicles and actuating machines.
