Abstract: A dirigible vehicle which is supported upon at least three ground engaging wheels located about the lower periphery of the device. Two of the three wheels are steerable while the third is fixed in position with its axis perpendicular to a line interconnecting the two steerable wheels. By manipulation of the steerable wheels, the vehicle may be adapted for movement along a linear path or may be made to spin about its own axis. Intermediate positioning of the steerable wheels will cause the vehicle to sweep in large circular arcs. The device may be self-propelled by a foot pedal assembly or by a small motor, with either a single steering wheel or dual independent steering controls. The unique steering capabilities of the vehicle make it ideally suited for recreational purposes or wherever extreme maneuverability is required.
