Abstract
A wheel lock for a wheelchair, where the wheelchair has a rear drive wheel, includes a housing adapted to be mounted on the wheelchair. The housing has two pivot points spaced apart in a forward/rearward direction. A wheel contact arm has a pivot shaft pivotally mounted about one of the pivot points. The wheel contact arm has a wheel engagement edge adapted to contact the rear drive wheel. The wheel lock also includes an actuation lever pivotally mounted about the other of the pivot points, and a linkage connecting the wheel contact arm and the actuation lever. The housing, the pivot shaft, the actuation lever and the linkage form a four bar linkage. Pivoting of the actuation lever causes pivoting of the wheel contact arm to engage the wheel contact edge with the rear drive wheel.
