ABSTRACT:
A wheelchair has a removable seat, removable battery containers and a body which can be separated into two major parts, one having a pair of ground-engaging wheels and the other having a single, steerable wheel. The body parts incorporate respective parts of a two-part coupling. One coupling part has recesses for receiving horizontal pins on the other coupling part. Lower pins serve as pivots during coupling. A pair of lower recesses are placed over co-axial lower pins and the body parts are then rocked about these pins to bring upper pins into their respective recesses. The pins are then locked in their recesses.
