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.

Claims

1. A device for assisting a handicapped person in traveling up and down a flight of stairs having vertically spaced steps, said device comprising a base adapted to rest on the tread of a step, said base including a lower platform disposed in a horizontal plane and having an upper surface located above the tread of the step, said base having an upper platform disposed in a horizontal plane and located above the upper surface of the lower platform, said upper platform being spaced from said lower platform along the length of the step whereby said platforms define a pair of stair treads located between and extending generally at right angles to the treads of adjacent steps, and a handle connected to and extending upwardly from said base to facilitate moving said device from step to step.

2. A device as defined in claim 1 in which said upper platform has one end located adjacent said lower platform, said handle extending upwardly from said base at a location adjacent the opposite end of said upper platform.

3. A device as defined in claim 2 in which said handle comprises a pair of upwardly projecting struts spaced from one another along said opposite end of said upper platform, and a horizontal bar extending between and joined to the upper ends of said struts.

4. A device as defined in claim 1 further including means enabling selective adjustment of the effective height of said handle.

5. A device as defined in claim 1 in which said base includes first and second upright risers spaced longitudinally along and extending transversely of said step, said first riser having a greater height than said second riser, a lower horizontal member extending between and joined to said first riser and the upper end of said second riser, a portion of said horizontal member defining said lower platform, a third riser extending transversely across and projecting upwardly from said horizontal member about midway along the length thereof, and an upper horizontal member extending between and joined to the upper ends of said first and third risers and defining said upper platform.

6. A device as defined in claim 5 in which said handle extends upwardly from said base at a position adjacent said first riser.

7. A device as defined in claim 1 in which said upper platform is spaced approximately 21/2 inches above said lower platform.
