ABSTRACT:
The folding cane apparatus includes a pair of front legs and a pair of rear legs which are attached together at the apex of the cane by a short common pivot rod. Both the front and rear pairs of legs include an inner tubular member telescoped into an outer tubular member so that the height of the cane may be adjusted. The outer tubular member of the front pair of legs is a continuous metal tube which also forms the handle of the cane. The structure of the cane provides for improved strength and stability, yet allows the user to collapse the apparatus to a relatively flat and storable size.
