Abstract

Disclosed is a hinged cane to assist in user mobility. The cane comprises an upper section and a lower section and a hinged mechanism that connects the upper and lower sections. The hinged mechanism comprises a lower block and an upper block and a hinge coupler pivotally connected to the lower block and to the upper block. This configuration enables the lower section to be moved from a use position over a range of travel into a fully folded position. The cane includes a catch mechanism for releasably securing the upper section to the lower section when in the use position. The cane may include a foot that has a relatively more pliable skirt and a relatively less pliable central nub to assist in maintaining the natural walking motion of the user.

First claim

What is claimed is:

1. A hinged cane comprising
an upper section and a lower section, and a hinge mechanism connecting said upper and lower sections;
said upper section having a generally tubular region at least in a lower region of said upper section, and having an operator gripping handle disposed at an upper region of said upper section;
said lower section having a generally tubular region at least in an upper region of said lower section, and having a foot disposed at a lower region of said lower section;
said hinge mechanism comprising a retractable block having a lower block portion disposed within said upper region of said lower section and an upper block portion disposed within said lower region of said upper section, and a hinge coupler, said hinge coupler being pivotally connected to said lower block portion and also being pivotally connected to said upper block portion to enable said lower section to be moved from a use position where said lower section is axially aligned relative to said upper section over a range of travel into a folded position;
one of said lower block portion and said upper block portion being retractable within its respective section;
said cane including a catch mechanism for releasably securing said upper section to said lower section, whereby a user may secure the lower section to the upper section by moving the lower section into axial alignment with the upper section causing an upper surface of said lower block portion to engage a lower surface of said upper block portion, and then axially translating said lower section relatively towards said upper section to cause retraction of said retractable block, said catch mechanism engaging when said lower section has been moved into a catch position relative to said upper block portion, said upper and lower block portions remaining in engagement when said catch mechanism is engaged.

2. The hinged cane according to claim 1 , said lower block portion being retractable within a tubular region of the lower section and said upper block portion being fixed relative to the upper section.

3. The hinged cane according to claim 1 , said catch mechanism comprising a spring-loaded catch button mounted on said upper block portion, said catch button engaging a catch opening in said generally tubular region of said lower section.

4. The hinged cane according to claim 1 , said generally tubular regions of said upper and lower sections having a cross-sectional profile that inhibits relative radial movement of said upper and lower sections when said lower section is secured to said upper section.

5. The hinged cane according to claim 4 , said generally tubular regions having a splined or slotted interior profile for engagement with a corresponding slotted or splined profile of said upper and lower block portions.

6. The hinged cane according to claim 1 , one of said upper and lower block portions being provided with a magnet and the other of said upper and lower block portions being provided with a corresponding magnet or metal to enable magnetic coupling of said upper and lower block portions when said upper section is brought into axial alignment with said lower section.

7. The hinged cane according to claim 1 , one of said upper section and said lower section including a magnet and the other of said upper section and said lower section including a corresponding magnet or metal, said magnet and said corresponding magnet or metal being axially positioned to engage one another and to magnetically couple said upper section and said lower section to one another when said cane is in a folded position.

8. The hinged cane according to claim 1 , one of said upper and lower sections being provided with an intermediate section, said intermediate section being retractable therewithin, the respective upper or lower section being provided with a plurality of height adjustment holes, the intermediate section including a height adjustment catch button engageable individually with said height adjustment holes to permit adjustment of the height of the cane.

9. The hinged cane according to claim 1 , said foot having a sufficient base area to permit said cane to be self-supporting on a flat surface.

10. The hinged cane according to claim 9 , said operator gripping handle having a crook, said crook accommodating nesting of said foot when said cane is in a folded position.

11. The hinged cane according to claim 9 , said foot comprising a relatively more pliable skirt and a relatively less pliable central nub.

12. A hinged cane comprising
an upper section and a lower section, and a hinge mechanism connecting said upper and lower sections;
said upper section having a generally tubular region at least in a lower region of said upper section, and having an operator gripping handle disposed at an upper region of said upper section;
an intermediate section that is retractable within said upper section, said intermediate section being provided with a plurality of height adjustment holes, said upper section being provided with a height adjustment catch button engageable individually with said height adjustment holes to permit adjustment of the height of the cane;
said lower section having a generally tubular region at least in an upper region of said lower section, and having a foot disposed at a lower region of said lower section;
said hinge mechanism comprising a retractable block having a lower block portion disposed within said upper region of said lower section and an upper block portion disposed within said lower region of said upper section, and a hinge coupler, said hinge coupler being pivotally connected to said lower block portion and also being pivotally connected to said upper block portion to enable said lower section to be moved into a use position where said lower section is axially aligned relative to said upper section over a range of travel into a folded position;
said lower block portion being retractable within said lower section;
said generally tubular regions of said upper and lower sections having a splined or slotted interior profile for engagement with a corresponding slotted or splined profile of said upper and lower block portions;
one of said upper and lower block portions being provided with a magnet and the other of said upper and lower block portions being provided with a corresponding magnet or metal to enable magnetic coupling of said upper and lower block portions when said upper section is brought into axial alignment with said lower section;
said cane including a catch mechanism for releasably securing said upper section to said lower section, said catch mechanism comprising a spring-loaded catch button mounted on said upper block portion, said catch button engaging a catch opening in said generally tubular region of said lower section;
whereby a user may secure the lower section to the upper section by moving the lower section into axial alignment with the upper section and causing said lower block portion to engage said upper block portion, and axially translating said lower section relatively towards said upper section to cause retraction of said retractable block relative to said lower section, said catch mechanism engaging when said lower section has been moved into a catch position relative to said upper block portion.

13. The hinged cane according to claim 12 , one of said upper region of said upper section and said lower region of said lower section including a closing magnet and the other of said upper region of said upper section and said lower region of said lower section including a corresponding closing magnet or closing metal, said closing magnet and said corresponding c
