Leg assembly for height adjustable patient support

A height adjustable patient support 1 has a frame 2, an actuator 12, a leg assembly 5 and a guide structure for longitudinally guiding an end of the leg assembly along the frame, the actuator being operable to pivot the leg assembly relative to the frame to raise and lower the frame between a lowermost position and an uppermost position, and a spring operable to longitudinally bias the end of the leg assembly when the frame is in the lowermost position so that the spring may assist with raising the frame from the lowermost position. The leg assembly preferably includes a mounting bracket (11, fig. 3) to mount the actuator to the leg assembly, the mounting bracket including an abutment plate engaging the spring. The guide is preferably in the form of a pair of tracks (18, fig. 5) which guide the mounting bracket to guide the leg assembly. The leg assembly may include rollers (17, fig. 5) to engage the tracks.

Leg assembly for height adjustable patient support

A height adjustable patient support has a frame, a pair of motor powered leg assemblies operable to vertically raise and lower the frame between a lowermost position and an uppermost position, a guide structure for longitudinally guiding an end of at least one of the pair of leg assemblies along the frame as the at least one of the pair of leg assemblies operates to vertically raise and lower the frame, and a non-motorized structure operable to longitudinally bias the end of the at least one of the pair of leg assemblies when the frame is in the lowermost position, the non-motorized structure mounted on the patient support by a mounting structure non-rigidly secured to the patient support. The non-motorized structure may assist with raising the frame from the lowermost position until motors operating the motor powered legs are able to continue with raising the frame.
