Walking cane

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.

2. The height adjustable walking cane of claim 1 , wherein said handle includes a handle grip portion disposed at an angle relative to a longitudinal axis of said outer tube.

3. The height adjustable walking cane of claim 1 , wherein said handle includes a button cover to prevent unwanted actuation of said actuating button.

4. The height adjustable walking cane of claim 1 , wherein said actuating assembly further includes a button spring between said button and said linkage, said button spring biasing said button to an extended button rest position when said actuation force is not applied to said actuating button.

5. The height adjustable walking cane of claim 1 , wherein said pin assembly further includes a pin carrier block fixedly mounted to a distal end of said central fixed rod, wherein said pin carrier block includes a pin bore dimensioned to slidably receive said pin therein and a lock pin passing through a lock pin aperture defined within said pin, wherein opposing ends of said lock pin are configured to travel within respective carrier slots defined within the pin carrier block.

6. The height adjustable walking cane of claim 5 , wherein said pin assembly further includes a lower pin travel block coupled to a second end of said translating member, wherein said lower pin travel block defines travel slots therein, wherein said opposing ends of said lock pin are further configured to travel within respective travel slots within said lower pin travel block.

7. The height adjustable walking cane of claim 6 , wherein said pin assembly further includes a pin assembly spring between said pin carrier block and said lower pin travel block, said pin assembly spring biasing said lower pin travel block to a first position.

8. The height adjustable walking cane of claim 6 , wherein said translating rod assembly further includes a lower bushing coupled to said pin carrier block and said inner tube, and a height spring mounted between a spring cap of said actuating assembly and said lower bushing, wherein said height spring biases said outer tube and said inner tube from the collapsed orientation toward the elongate orientation when said pin is in said retracted position.

9. The height adjustable walking cane of claim 6 , wherein said carrier slots are disposed at an angle relative to said travel slots.

10. The height adjustable walking cane of claim 1 , wherein each of said outer tube and said inner tube define a generally D-shaped cross section having a curved portion and a planar portion, wherein said planar portions are adjacent one another when said inner tube is received within said outer tube.

11. The height adjustable walking cane of claim 10 , wherein said plurality of apertures defined within said inner tube are located within said planar portion.
