Abstract:

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.
