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.
Claims2
A cane fitted with retractable strut legs that are each pivotally joined to a lower section of the cane, said struts each fitted with pivotable brace means that extend the strut legs away from the lower section of the cane, when the bottom tip of the cane is pressed against a surface by the user, together with spring means that bias each strut to retract towards the cane, said bottom tip of the cane fixed to a member slidably telescopically extending from the said lower portion of the cane, and linked to said brace means.
A cane fitted with retractable strut legs that are pivotably joined to the cane, said struts each fitted with brace means that extend the strut legs away from the cane when the cane is pressed against a surface by the user, together with spring means that bias each strut to retract towards the cane, in which
- the said cane comprises
- a handle fixed to a first end of a tube,
- said tube formed with a hollow axial chamber extending from the second end of said tube,
- a piston member slidably mounted in said chamber and spring biased to extend a tip of the piston beyond the said second end of the tube,
- a plurality of leg struts individually pivoted to the tube and located so that each strut extends beyond the said second end of the tube when the strut is folded adjacent to the tube, with the tip of said piston member extending a greater distance from the tube end in said folded position, together with said brace means comprising
- brace members each pivotably fastened to a strut and to the piston member, with each brace member extending through a slot in the tube.
