1. A height adjustable walking cane selectively positionable between a collapsed orientation, an elongate orientation and a plurality of intermediate orientations therebetween, comprising:
a) an outer tube having a top end and a bottom end and defining a pin hole proximate said bottom end, and further including a handle mounted to said top end of said outer tube;
b) an inner tube slidably received within said outer tube, said inner tube having an inner tube wall defining a plurality of apertures therethrough;
c) a translating rod assembly having a central fixed rod and a concentrically mounted translating member;
d) an actuating assembly including an actuating button proximate said top end of said outer tube and coupled to a first end of said translating member, wherein said actuating assembly resides within at least a portion of said handle; and
e) a pin assembly located at said bottom end of said outer tube and comprising a pin adapted to selectively reciprocally translate between an extended position wherein said pin engages a selected aperture of said plurality of apertures defined within said inner tube wall and said pin hole defined in said outer tube, and a retracted position wherein said pin disengages from said pin hole defined in said outer tube,
wherein said actuating assembly further includes:
i) a linkage pivotally mounted to the portion of the handle;
ii) a rod driver having a first driver end coupled to said translating member;
iii) a button post having a first post end coupled to said actuating button and a second post end coupled to said linkage; and
iv) a link arm having a first link end coupled to said linkage and a second link end coupled to said rod driver,
wherein said handle mounted to said top end of said outer tube slidably secures said actuating button therein, and
wherein application of an actuation force upon said actuating button drives said button post against said linkage thereby pivoting said linkage and causing said linkage to drive said link arm against said rod driver whereby said rod driver engages said translating member and causes said pin to move from said extended position to said retracted position such that said inner tube slidably translates within said outer tube.
