<p>Subject of the invention is a mechanism for manual driving of a three- or more wheel vehicle, which enables the transfer of circular manual movements via a gearing of the main gearwheel (1) and intermediate gearwheels (2, 2') via friction wheels (2a, 2b, 2a', 2b') to the driving wheel (4) of the vehicle according to the gear ratio, and simple control of driving forwards or backwards providing the possibility of braking and instantaneous stopping or blocking of the driven wheel (4). The concept of the mechanism is made in such a way that it can be simply attached or installed to an existing vehicle, e.g. wheelchair.</p> |
