An ambulance cot is disclosed and the ambulance cot having a base frame configured for support on a surface, a litter frame configured for supporting thereon a patient and an elevating mechanism interconnecting the base frame and the litter frame and configured to interconnect the litter frame and the base frame in order to facilitate movement of the base frame and the litter frame toward and away from each other. A control mechanism is provided on the cot which is configured to facilitate the movement of the base frame and the litter frame toward each other and at differing speeds predicated on at least one of whether the base frame is supported on the surface and the litter frame is supported by an external support separate from the elevating mechanism.

The present invention is directed to a stair chair. The stair chair includes a seat assembly mounted to a main frame and configured to pivot about a first pivot axis. A rail assembly having two laterally spaced brackets provided at a lower end of the rail assembly is included. A back wheel is rotatably supported on each bracket for rotation about a common axis of rotation. At least two mounts are provided at a lower end of the main frame, each of which is configured to pivotally connect one of the brackets to the main frame for movement about a second pivot axis. The rail assembly and seat assembly are configured to pivot about their respective pivot axes independent of movement of one another. A first spacing exists between the axis of rotation of the front wheels and the axis of rotation of the back wheels when the rail assembly in a retracted position and a second spacing exists between the axis of rotation of the front wheels and the axis of rotation of the back wheels when the rail assembly in a deployed position.
