(21) 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. The modification is achieved by jacking apparatus 23 asso- ciated with each drive wheel 21. The jacking apparatus has a lever 24 adapted to be moved to a self-locking position which downwardly urges a connecting rod 26, causing telescopic displacement of a rear caster wheel 29. Such downward displacement of the rear caster wheels lifts the rear drive wheels off the underlying support surface.
