Abstract:
1. Walking aid apparatus comprising a handle portion and a shaft portion including a ground-contacting ferrule, the handle and shaft portions comprising telescopically-mounted relatively rotatable elements, said shaft portion comprises a tube and the inner or the outer telescopically-mounted element is mounted to the tube by a grip arrangement comprising an O-ring carried in an annular groove formed in the element and having a chamfered wall, whereby the ring is forced into jamming engagement with the inner wall of the shaft portion on any attempted withdrawal of the element from the shaft portion; and including spring means resiliently to restrain relative compression movement, characterized in that the spring means comprise a resilient elastomeric material which is rotatable relative to at least one said element, whereby rotation between the handle portion and the ferrule accommodates twisting movement as between the user and the ground in a controlled manner.
