Abstract
A height adjustable walking aid includes an outer tube and an inner tube slidably received within the outer tube. Adjustment is made using a, actuating assembly and pin assembly. Application of an actuation force upon the actuating assembly engages a translating member within the translating rod assembly to drive a lower pin travel block of the pin assembly from a first position to a second position. A pin then travels from an extended position to a retracted position such that the inner tube may slidably translate within the outer tube
Claims9
A height adjustable walking aid 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;
- 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 located at said top end of said outer tube and coupled to a first end of said translating member;
- and
- e) a pin assembly located at said bottom end of said outer tube and comprising:
- i) 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;
- ii) 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;
- and
- iii) 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,
- wherein application of an actuation force upon said actuating button engages said translating member to drive said lower pin travel block from a first position to a second position whereby said lock pin travels in said travel slots and said carrier slots to move said pin from said extended position to said retracted position such that said inner tube slidably translates within said outer tube.
