Abstract: A device for helping a handicapped person move up and down a flight of stairs. The device includes a base having a pair of vertically spaced platforms which define intermediate steps between the steps of the stairs. By stepping from a lower step to the platforms and then to the adjacent upper step, a person may climb the stairs while lifting his feet vertically through only relatively short distances. A handle extends upwardly from the base and helps stabilize the person using the device. The handle also is used to move the device from step to step.

Abstract: A circular ladder for use along a cylindrical wall and having a single stringer which is disposed in a helical path around the cylindrical wall and an array of half treads disposed on each side of the stringer. Each array of half treads is vertically spaced from the other along the length of the stringer, the half treads being affixed to and laterally extending from the respective sides of the stringer. Each half tread includes an outwardly extending portion which terminates in a plane which is forward of a plane passing through the front edges of the treads. First and second handrails are disposed in this forward plane and affixed to the outwardly extending tread portions. In an alternative embodiment, a single outside handrail is employed, the cylindrical wall providing a body support in place of an inside handrail.
