ABSTRACT:
A wheelchair wheel locking assembly comprises a first wheel stop having an actuating lever for operating a first wheel-engaging member. The first wheel stop is operably connected to a second wheel stop via a continuously flexible linkage, whereby actuating the first wheel stop simultaneously operates the second wheel stop. In the event the continuously flexible linkage is severed, the first wheel stop may continue to be operated by the actuating lever. The wheel locking assembly of this invention is advantageously operated from a single side of a wheelchair. A wheel locking assembly having dual actuating levers is also provided, whereby from a single side of a wheelchair a first actuating lever operates a first wheel-engaging member and a second actuating lever operates a second wheel-engaging member.
