ABSTRACT:
A brake device for use with wheelchairs of the type having a main frame and a pair of spaced apart large diameter driving wheels, such as rear wheels. The brake device is to be engaged by a secondary operator of a wheelchair and comprises a bracket or other mounting element for mounting to the wheelchair handles and a brake arm which is shiftable to a wheel locking position to move an actuator tube and attached stopper into engagement with the rear wheel of a wheelchair to lock the wheel against further rotation. The brake arm is also capable of being shifted to a reverse or non-locking position so that it moves the actuator tube and attached stopper out of engagement with the wheelchair driving wheel to a position where it can not be engaged with the driving wheel to permit free-wheeling movement thereof. The brake device is constructed so that the actuator tube and attached stopper is moveable to a non-interfering position where it is generally perpendicular to the plane of rotation of the wheel and is not likely to be contacted by the hand of a user.
