Abstract: A wheelchair wheel lock system for a wheelchair having a wheel lock plate with a locking face. The system includes a control cable, a lock-pin, a remote actuator and a biasing member. The control cable operatively connects the lock-pin with the remote actuator. The lock-pin is positioned proximate the locking face and selectively engages and disengages with the locking face when urged by the actuator. The biasing member urges the lock-pin to disengage from the locking face.

Abstract: A plate assembly for a wheelchair having a wheel lock system for a spoked wheel. The wheel lock assembly includes an actuator that moves a lock-pin between locking and unlocking positions with the wheel. The plate assembly has three generally flat plates attached together by a double ring of bolts with pliant nuts. The first plate is metal and releasably engages the lock-pin. The other two plates are made of pliant material, and mate from opposite sides of the spokes to form elongated radial channels. Each channel snugly receives one of the spokes along a substantial length of the channel.

Abstract: A lever assembly for a wheelchair having a wheel lock system with two wheel lock assemblies.
