Abstract: A clamping device is provided having a stabilizing plate, a retainer shaft cooperating with the stabilizing plate which includes a ratchet end, an elbow and clamp, twisting means for tightening the clamp, and quick release ratchet means to allow an object to be quickly secured between the plate and clamp and movably riding over the ratchet, which clamping device can act cooperatively with a mast to form a bed trapeze securing device.

Abstract: A mechanism for providing varying degrees of elevation to separately movable head-rest and back-support sections. Head-rest and back-support sections are pivotable about points on a frame section and are pivotally connected to one another to allow controlled reclining movements. A drive motor powers a positioning device to allow the back-support section to vary from upright to horizontal. When the positioning device engages a deflector at the head of the bed, the head-rest section tilts upward to form a pillow even though the back-support section remains horizontal.
