Title: All level cart with swivel casters

Abstract: An ambulance cart having a bed from which four legs depend. The legs are adapted to swing away from each other to lower the level of the cart. An extensible frame is mounted at the lower ends of the legs, and casters adapted to swivel about vertical axes are attached to the frame so that as the legs are spread apart the frame enables the casters to maintain the vertical orientation of their swivel axes. Both forward and rearward legs are also adapted to swing rearwardly to enable the cart to be thrust into a vehicle.
