Abstract:
1. An ultra-low patient bed comprising: a frame supported by front and rear legs, the front and rear legs having an upper end and a lower end, the front and rear legs both movable independently and simultaneously to raise and lower the frame, wherein a leg brace is pivotally connected to the frame and pivotally connected to at least one of the legs; a first linear actuator configured to provide for movement of the front legs, and a second linear actuator configured to provide for movement of the rear legs, wherein the first and second linear actuators act on the corresponding legs in a direction substantially parallel to the frame; a caster support member having a longitudinally extending portion directly pivotally connected to the lower end of each leg; a caster assembly connected to each of said caster support members, each caster assembly having a caster and having a substantially vertical orientation that allows each of said casters to swivel in response to directional changes of the bed, wherein each of the caster assemblies associated with the front legs is independent from the caster assemblies associated with the rear legs; and a constraint structure configured to maintain the substantially vertical orientation of each of the caster assemblies at all height positions of the bed, wherein the front legs and the rear legs are mechanically driven independent of one another and simultaneously when the frame is raised horizontally.
