ABSTRACT:
A walking cane fitted with three articulated struts that are each linked to a slidable spring-biased piston in the foot of the cane, and joined together so as to extend away from the foot of the cane when the piston is pushed against the ground and upwards into the cane, with the extended struts acting to support the cane in tripod fashion. Release of downward pressure against the piston permits the spring to slide the piston downwards and retract the three struts.
