Abstract
A cane includes a tube, an extension rod telescopically mounted within one end of the tube, and a control mechanism sandwiched between the tube and the extension rod. The tube defines a first aperture and a second aperture. The extension rod defines a plurality of holes. The control mechanism is movable among a first position where the control mechanism is positioned in a selected one of the holes in the extension rod, and the tube, the extension rod and the control mechanism are prohibited from moving axially with respect to one another; a second position where the extension rod and the control mechanism together are allowed to move axially with respect to the tube; and a third position where the extension rod is allowed to move axially with respect to the control mechanism and the tube.
