ABSTRACT:
Disclosed is a safety handle for turning a hand control wheel. The handle is engaged by exerting constant axial pressure on the handle in a swung-out position, which enables the hand control wheel to be turned. Upon release of the handle, it automatically swings back to the retracted position into the hand control wheel. The handle is locked in the wheel-turning position by way of a shoulder/detent engagement.
