ABSTRACT:
A wheelchair having a hand operated steering mechanism that can be easily mounted and/or dismounted from the chair. The mechanism involves a steering rod having a center section cojoined to an upper section and a lower section by means of a pair of universal joints. The lower section of the shaft is slidably secured to the fork of one of the chair casters and the top section is rotatably mounted in a bearing block which is, in turn, secured to the front column of one of the chair arms. A crank arm is slidably received in the top section of the steering rod to provide sufficient leverage by which the chair occupant can turn the caster. An adjustable locking mechanism is also operably associated with the shaft for holding the caster at a desired position to prevent the chair from moving in an uncontrollable manner.
