ABSTRACT:
A telescopic combined crutch and walking stick, having a lower ground-engaging tube; a middle tube mounted slidably and non-rotatably in the ground engaging tube and lockingly therein for positioning it in the lower tube in one of several selectable positions; and an upper tube mounted slidably and non-rotatably in middle tube and lockingly therein for positioning it in the middle tube in one of several selectable positions. The tubes are of a length such that, when they are fully retracted one into the other, the length of the combined crutch and stick is about 1/3 the length when fully extended. The combination further includes an armpit support mounted at the upper end of the upper tube, and a walking stick handle mounted at the upper end of the middle tube.
