A wheelchair has a detachable drive means so that it is useful both indoors under manual power and outdoors under motor power. The drive means is manipulable by the occupant himself, and to this end comprises a drive wheel and motor with steering handle bars, and means to detachably interconnect this assembly at each side of the wheelchair. The connecting means comprises ramps that guide laterally sliding pins toward their sockets, and rotatable cams received in vertical slots at the forward ends of the wheelchair armrests. |
