ABSTRACT:
A patient lift includes a frame attached to a vertical surface. The frame includes first and second vertical guide posts with a parallel screw shaft rotatably mounted therebetween. A hub engages the screw shaft and travels up and down the screw shaft according to a direction of rotation of the screw shaft as provided by a drive train coupled to the drive shaft. Upon connection of the head end of the bed frame to the hub, the head end travels with the hub so as to move the bed between horizontal and vertical positions relative to the underlying support surface. A roller member at the foot end of enhances the movement of the bed frame between the ground adjacent horizontal and vertical positions. A foot rest at the foot of the bed precludes the patient from sliding forward during bed movement. An alternative embodiment connects a chair so as to raise or lower the seated patient relative to the underlying support surface.
