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.

1. A wheel locking assembly for substantially preventing rotation about an axis of a wheelchair wheel or tire, comprising:a first wheel stop and a second wheel stop for mounting to opposite sides of a wheelchair frame: said first wheel stop including a mounting bracket, a first displaceable wheel-engaging member, and an actuating lever operably connected to said first displaceable wheel-engaging member; and said second wheel stop including a mounting bracket and a second displaceable wheel-engaging member; and substantially continuously flexible linkage connecting said second displaceable wheel-engaging member to said first displaceable wheel-engaging member; whereby biasing said actuating lever in a first direction pivots the first wheel-engaging member into contact with a first wheel or tire and concurrently pivots the second wheel-engaging member into contact with a second, opposed wheel or tire of said wheelchair, and biasing the actuating lever in a second, opposed direction concurrently pivots the first and second wheel-engaging members away from contact with the first and second wheel or tire. 2. The wheel locking assembly of claim 1, wherein said actuating lever remains operably connected to the first wheel-engaging member if the continuously flexible linkage operably connecting the first and second wheel-engaging members is severed.3. The wheel locking assembly of claim 1, wherein said wheel-engaging member includes a wheel-contacting surface having a cutout for grippingly engaging a resilient ground-engaging portion of the wheel or tire.4. The wheel locking assembly of claim 3, wherein said wheel-contacting surface cutout is substantially concave.5. The wheel locking assembly of claim 1, wherein said substantially continuously flexible linkage comprises a flexible member having a first end operably connected to the first wheel-engaging member and a second end operably connected to the second wheel-engaging member.6. The wheel locking assembly of claim 5, wherein said continuously flexible linkage is a push-pull cable comprising a substantially flexible outer sheath surrounding and spaced from a substantially flexible wire.
