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 comprises a bracket or other mounting element for mounting to the wheelchair frame and a lever arm which is shiftable to a wheel locking position to move a brake tab into engagement with the rear wheel of a wheelchair to lock the wheel against further rotation. The lever arm is also capable of being shifted to a reverse or non-locking position so that it moves the tab out of engagement with the wheelchair driving wheel and to a position where it cannot be engaged with the driving wheel to permit free-wheeling movement thereof. The brake device is constructed so that the tab is moveable to a non-interfering position where it is generally parallel to the plane of rotation of the wheel and is not likely to be contacted by the hand of a user. In one embodiment, the tab is manually moveable to the non-interfering position. In another embodiment, the tab is automatically moved to the non-interfering position when the lever arm is shifted away from the locking position.
