Abstract
The present invention is a self-aligning walking aid that is suitable for use walking on level surfaces and for ascending and descending stairs. Disclosed is a walking aid that is equally stable on level surfaces and on stairs and that does not require any structural or positional changes when transitioning from a level surface to stairs. The preferred embodiment herein discussed is configured so as to limit appropriate graspable frame members so that when lifted by the appropriate pair of handles, the walking aid will swing into alignment with the surface, level surface or stairs, on which it is being used.
Claims6
A stair compatible walking aid for use on level surfaces and stairs, comprising:
- (a) an open ended framework;
- (b) said framework being supported at a closed end by at least two spaced apart front legs;
- (c) said framework being further supported at said open end by at least two spaced apart rear legs, said front legs and said rear legs being spaced apart by a distance that spans a plurality of steps when the walking aid is deployed on stairs of standard rise and run;
- and
- (d) said framework including a pair of parallel spaced apart side toprails configured such that both said side top-rails include a first handle-portion that is substantially horizontal when the walking aid is deployed on a level surface, said first handle-portion being spaced above said level surface at a first height, both said side top-rails further including a second handle-portion that is a downwardly sloping continuation of said side top-rails;
- whereby, said first handle-portions are distal to said closed end of said framework and said second handle-portions are proximal to said closed end of said framework, said first handle-portions including a first pair of handles located such that as the walking aid is lifted by grasping said first pair of handles said front legs and said rear legs come into alignment for deployment on a level surface, said second handle-portion including a second pair of handles located such that as the walking aid is lifted by grasping said second pair of handles said front legs and said rear legs come into alignment for deployment on stairs.
