ABSTRACT:
A steerable, powered, front wheel driven, three-wheeled vehicle for a handicapped person which is movable selectively in a forward or rearward direction and has a vehicle frame supported in part by a pair of transversely spaced rear wheels suitable for indoor travel, is adapted to outdoor use by backing its rear wheels onto a transversely extending, auxiliary frame supported on a pair of transversely spaced driven outdoor wheels. The auxiliary frame has a transversely extending cradle mounted such that, in a first forwardly and downwardly tilted position of the auxiliary wheel frame, the forward portion of the cradle rests substantially on the ground and, in a second position, in which the frame is generally level, the front and rear portions of the cradle are both disposed above the ground, and the rear wheels of the powered vehicle are supported by the cradle above the ground. A latch part mounted by the powered vehicle frame near its rear end is releasably engaged by a cooperative latch member operated responsive to tilting movement of said auxiliary wheel frame from tilted to generally level position to latch the vehicle to the auxiliary frame for travel as an integrated vehicle.
