A BED ELEVATOR

摘要: An elevator mechanism for varying the height and/or orientation of a frame or platform (14) bed. The includes head end linkage assembly (1 7) and foot 8) each which is adapted sliding coupling (23) to (14). (17) being coupled an axle shaft (20) ("head axle"). (18) (35) ("foot A first actuator (31) lever (28) extending from (20). second (41) (43) (35). In use operation actuators (31, 41) cause axles (20, 35) rotate about their longitudinal axes thereby result in movement link assemblies (17, 18).
