Abstract:
A bed includes a base frame having a head end and a foot end, an elevatable frame also having a head end and a foot end, a lift assembly or comprising an actuation system connected to one of the frames, a push chain having an actuator end driven by a lead screw and a distal end connected to the other of the frames. Rotary motion of the lead screw changes elevation of the elevating frame relative to the base frame.
