Abstract
A manually propelled device includes two base modules having at least two wheels interconnected by a pedal element. The device is provided with at least four wheels which are parallel with each other. The pedal elements each interconnect two of the wheels and are fixed to the two interconnected wheels at points off-set from the centers of the two wheels. A shaft interconnects the centers of one of the wheels of each of the modules, thereby interconnecting the modules. Pedaling of the pedal elements by the feet of an operator serves to cause rotation of the wheels in a same rotating direction to propel the device in a selected linear direction.

A propelled device comprising:
- at least two base modules, each of said base modules comprising two wheels interconnected by a pedal element;
- at least four of said wheels being parallel to each other;
- each of said pedal elements being attached to said two of said wheels in the manner of a pedal crank, in that said pedal elements are each fixed to said two wheels eccentrically with respect to respective wheel center points and said pedal elements are each offset with respect to a longitudinal axis of the other of said two pedal elements;
- wherein one of the wheels of each of said modules is connected to another of said wheels by a shaft fixed to a center of each of said two wheels.
