ABSTRACT:
An improvement is made in a wheelchair having front caster wheels and rear drive wheels whereby the seated occupant can unaidedly cause the wheelchair to have lateral mobility and can remove the drive wheels. Said modification is achieved by jacking apparatus associated with each drive wheel. The jacking apparatus has a lever adapted to be moved to a self-locking position which downwardly urges a connecting rod causing telescopic displacement of a rear caster wheel. Said downward displacement of the rear caster wheel lifts the rear drive wheel off the underlying support surface.
