The shaft is formed of at least two telescoping, adjustable sections that allow the height of the shaft to be selectively varied. Near the upper end of the shaft is a motorized armrest that can be raised to a horizontal position to support a user's arm or elbow. Slidably mounted on a lower portion of the shaft is a deployable leg assembly for firmly bracing the cane when a user leans on the armrest. Accordingly, if a user wishes to rest, he or she deploys the leg assembly and raises the armrest allowing the cane to easily support the user's body weight. When the armrest and leg assembly are collapsed, the cane may be used in a conventional fashion. ## Claims ### Claim 1 An improved walking cane comprising: an elongated shaft having an upper end and a lower end; a pivotal armrest mounted on said shaft, proximal the upper end, on which a user leans to rest; a deployable leg assembly slidably mounted on a lower portion of said shaft for firmly bracing said shaft when a user leans on said armrest; a pivotal brace member extending from a lower surface of said armrest, a distal end of said brace member pivotally attached to a threaded annulus riding on a rotatable bolt mounted on said shaft; and a reversible motor operably connected to said bolt for rotating said bolt in either of two directions to axially translate the annulus to raise and lower said armrest. ### Claim 2 (depends on 1) The cane according to claim 1 wherein said leg assembly comprises: a collar slidably mounted on said shaft; a plurality of pivotal support legs radially extending from said collar. ### Claim 3 (depends on 2) The cane according to claim 2 further comprising reflective tape attached to the intermediate portion of each of said legs. ### Claim 4 (depends on 2) The cane according to claim 2 wherein each of said support legs includes pulsing LEDs mounted on an intermediate portion to visibly enhance said leg assembly. ### Claim 5 (depends on 4) The cane according to claim 4 further comprising a handle at an upper end of said shaft. ### Claim 6 (depends on 5) The cane according to claim 5 wherein said LEDs and said motor are controlled with a switch panel mounted on said handle. ### Claim 7 (depends on 5) The cane according to claim 5 wherein said handle is L-shaped and includes a foam sleeve thereon. ### Claim 8 (depends on 2) The cane according to claim 2 wherein each of said support legs includes a foot at a distal end, said foot having an angled lower surface that becomes substantially horizontal when the legs are fully deployed for flatly abutting an underlying surface to prevent shifting and slipping. ### Claim 9 (depends on 2) The cane according to claim 2 wherein said collar includes a spring-biased pin attached thereto, said pin releasably fitting within either of two holes on said shaft to secure the leg assembly in either a collapsed or a deployed position. ### Claim 10 (depends on 2) The cane according to claim 2 wherein said support legs each include a pivotal strut extending from said leg to said shaft to buttress the legs when the leg assembly is expanded, said struts unobtrusively folding into storage slots on said legs when the leg assembly is collapsed. ### Claim 11 (depends on 1) The cane according to claim 1 wherein said shaft is length adjustable. ### Claim 12 (depends on 1) The cane according to claim 1 wherein said shaft is formed of at least two telescoping sections adjustably connected with a compression fitting for selectively varying a height of said shaft. ### Claim 13 (depends on 1) The cane according to claim 1 wherein said armrest includes a padded upper surface.
