ABSTRACT:
A rugged, lightweight wheelchair may be readily disassembled and packed into a relatively small size shipping container. The back and footrest sections include pushbutton release elements which separate those sections from the side frames of the chair. The side frames are connected to each other through a scissors mechanism which allows the chair to collapse sideways. The disassembled parts can very easily be placed into a regulation size shipping container. A strong steel spine which includes two welded portions gives the side frames extra strength. Most of the rest of the chair is made up of lightweight metals and fabrics. The front wheels of the wheelchair include a bracket and pin combination which reduces undesirable twisting moments. The wheelchair also includes other improved features which make it exceptionally rugged for a device of such lightweight construction.
