ABSTRACT:
Raisable safety side apparatus for one or both sides of a hospital bed comprising in each instance a corresponding side frame pivotally connected to lever means, e.g. a pair of spaced apart or parallel levers, adapted to be mounted operatively on a bed to move the side frame from a lower or inoperative position to an upper or operative position with respect to the bed, and resilient biasing means operatively interposed between the frame and the lever means to urge normally the frame to the upper position, e.g. a longitudinal bilateral resilient biasing member mounted intermediate its ends on the frame and operatively connected at its ends to the corresponding levers, such as crank levers, whereby to bend the bilateral biasing member out of its normal longitudinal disposition as the levers move the frame from the upper position to the lower position against the resilient force of such bilateral biasing member; and optionally including means to limit the pivotal movement between the frame and the lever means upon moving the frame to the upper position, and releasable locking means to maintain the frame in the upper position.
