ABSTRACT:
An ambulatory aid in the form of a cane is manufactured from plastics material including a handle and a stick portion. The stick portion is formed in two sections, one having a male screw thread and the other having a female screw thread so that the axial length can be adjusted by screwing one into the other and then locking with a lock nut. The screw threads are formed of moulded plastic material in tubular form with a tubular metal insert. The handle is shaped with an inclined upper surface leading downwardly to an upward stop. The upper surface is positioned directly above the vertical axis of the stick.
