ABSTRACT:
An arrangement of interlocking telescoping members, having particular applicability with invalid devices, such as walking canes, foldable walkers and the like, includes an outer telescoping member having a plurality of longitudinally arranged apertures; an inner telescoping member telescopically received within the outer telescoping member, the inner telescoping member including a single aperture; a push button extending outwardly through the aperture of the inner telescoping member for engagement with one of the longitudinally arranged apertures of the outer telescoping member; a spring disposed within the inner telescoping member and secured to the push button for outwardly biasing the push button through the aperture of the inner telescoping member; and a plastic, resilient sleeve snuggly surrounding the outer telescoping member at least about the longitudinally arranged apertures so as to provide a pinch free adjustment, to prevent rattle between the telescoping members, and with the sleeve being capable of having different colors thereon.
