Abstract
A height adjustable cane includes an upper tubular member configured to slidably receive a second tubular member in a telescoping manner. A plurality of apertures are formed in the first tubular member which allows a button of a snap button assembly to pass therethrough and lock the tubular members against relative movement. Using the push-button assembly and the telescopic feature, the length of the cane may be adjusted. Increased stability between the tubular members is provided by a cam locking assembly including a housing receiving a cam member. The cam member includes a lever and a raised camming surface that selectively engages an outer surface of the second tubular member.

An adjustable cane comprising:
- a first member having a plurality of spaced apertures and an opening;
- a second member adapted for telescoping relation with the first member;
- a handle located at an end of one of the first member and the second member;
- a snap button assembly at least partially housed inside of the second member and having a button on a first end extending radially outward through one of the apertures in the first member;
- a cam locking assembly located adjacent the opening including a housing receiving a cam member with a raised surface, and a cam lever operatively associated with the cam member for selectively engaging the raised surface with the second member through the opening of the first member.
A height adjustable cane comprising:
- a first tubular member having a plurality of spaced apertures;
- a second tubular member configured to be received within the first tubular member and having at least one aperture formed thereon, and a snap button at least partially contained in the second tubular member and adapted to pass through the at least one aperture in the second tubular member and one of the apertures in the first tubular member;
- a handle located at an end of one of the first member and the second member;
- and
- a cam locking assembly including a housing mounted on an outer surface of the first tubular member and a cam member located within the housing including a lever and a raised surface extending from the cam member, wherein movement of the lever positions the raised surface in contact with the second tubular member.
