Wheelchair drive mechanism

A wheelchair which shifts between forward and reverse by virtue of a roller mechanism which grabs in one direction and slips an opposite direction, thereby preventing binding. The shift mechanism is initiated by rotation of a shift paddle which is located on a extremity of a lever arm remote from the roller mechanism.

WHEELCHAIR BRAKING DEVICE

A wheelchair braking device providing a braking action that automatically disengages when an occupant is seated in the wheelchair. The braking device includes a support structure to which a sensing lever is pivotably mounted and to which a braking arm is slidably mounted. A biasing element is coupled to the braking lever to bias the braking arm in a first direction relative to the support structure and into engagement with a wheel of the wheelchair, thereby inhibiting rotation of the wheel. The sensing lever and braking arm are interconnected such that the biasing element operates through the braking arm to bias the sensing lever in an upward direction against the wheelchair seat. The interconnection between the sensing lever and braking arm causes the braking arm to disengage from the wheel when the sensing lever rotates in a downward direction.

Wheel hub locking mechanism for wheelchair

Abstract
A wheelchair wheel hub locking mechanism is provided to positively lock a wheelchair wheel to the associated wheelchair frame and includes a locking ring member of cylindrical shape fixed to the inner side of the wheelchair wheel hub, the locking ring providing a plurality of dog receiving cages, each cage presenting a dog receiving opening formed by surround walls integral of the ring. A dog and dog mounting plate are mounted to a member of the wheelchair frame, the position of the dog being controlled by movement of an association handle connected by a cable to the dog, forward movement of the handle raising the dog away from cages of the locking ring, movement of the handle rearwardly of the wheelchair allowing the dog under spring bias to move against the locking ring until wheel movement aligns a cage of the ring with the dog and the two lock up.
