Abstract

A combined stability cane and device for assisting a handicapped person in traveling up and down a flight of stairs having vertically spaced steps is disclosed. A rectangular block member or platform has a flat upper surface within which a connector mechanism is provided at its central area, and a second connector mechanism is provided in the upper surface adjacent one of the sides of the block member and opposite the central area. A walking cane having a cooperative connector mechanism adjacent its lower end is provided to alternatively rigidly connect the same to one of the two connector mechanisms in the upper surface of the block member. When the cane is connected to the connector mechanism at the central area of block member, the combination functions as an excellent stability cane. When the cane is connected to the connector mechanism adjacent one side of the block member, the latter functions as a half-step which the handicapped person may utilize to facilitate travel up and down the steps by taking only a half-step at a time, at first on the block member and then upon the next step, thereby reducing the elevation change required through a series of half-steps. Alternatively, the walking cane may be disconnected from the block member so as to use the same in its normal manner.

(c) said platform having a first connector mechanism disposed at said upper surface adjacent one of said sides intermediate said forward and rearward ends;

(d) an elongated walking cane member having upper and lower ends and a cooperative connector mechanism at said lower end for cooperatively and rigidly engaging said platform connector mechanism in a readily releasable locking relationship adjacent said one side of said platform and outwardly of said central area while extending normal thereto, to thereby provide a device for assisting the handicapped person in traveling up and down the flight of stairs having vertically spaced steps; and

(e) said platform having a second platform connector mechanism located near said central area of said upper surface of said platform for cooperative optional engagement with said connector mechanism of said walking cane to provide a broad-based stability cane for the handicapped person.

5. The structure defined in claim 4, wherein said connector mechanism of said walking cane cooperatively and rigidly engages said second platform connector mechanism in a readily releasable pivotally keyed locking relationship.

6. The structure defined in claim 4, wherein said connector mechanism of said walking cane includes a compressive spring which engages said upper surface of said platform to maintain said walking cane in releasable locking relationship with either of said platform connector mechanisms.

7. The structure defined in claim 4, wherein each of said platform connector mechanisms includes a rigid socket disposed beneath said upper surface of said platform for receiving said lower end portion of said walking cane in close-fitting supporting relation when said cane is connected in locking relation therewith.

13. A combined stability cane and device for assisting a handicapped person in traveling up and down a flight of stairs having vertically spaced steps comprising:

(a) an elongated generally rectangular block member having parallel, generally flat upper and lower surfaces and having vertical dimensions of approximately four inches;

(b) said block member having forward and rearward ends, opposite sides, and a central area at said upper surface;

(c) first connector mechanism carried by said block member at said upper surface at said central area;
