Abstract
The collapsible crutch includes an elongated head section, at least upper and lower elongated, hollow midsections, and an elongated foot section. The head section has a mechanism for supporting a portion of the person using the crutch. The midsections are connected together by an elastic cord. A detachable coupler connects the head section to the upper midsection and a similar detachable coupler connects the lower midsection to the foot section. In an assembled mode, these sections are substantially axially aligned. The collapsible crutch also includes a coupling mechanism that provides a conjoined, axially and laterally stable, subassembly of the upper and lower midsections.
Claims17
A collapsible crutch for a person comprising:
- an elongated head section having, at its upper terminal end, means for supporting a portion of said person;
- at least upper and lower elongated, hollow midsections;
- first means for detachable mounting a lower end of said head section to an upper end of said upper midsection;
- elastic means coupling said upper and lower midsections together, said elastic means extending through an interior region in both said upper and lower midsections;
- coupling means having an upper extension that is adapted to be inserted into and closely fitted to an interior, lower terminal end region of said upper midsection, said coupling means having a lower extension that is adapted to e inserted into and closely fitted to an interior, upper terminal end region of said lower midsection, said elastic means extending through said coupling means, said coupling means substantially axially aligning said upper and lower midsections when inserted therein;
- means for respectively latching said upper and lower extensions of said coupling means to said upper and lower midsections, said means for latching includes at least one pin passing through holes in one of the closely fit extensions and midsections;
- a hand hold on one of said upper or said lower midsections;
- an elongated foot section having a lower terminal end adapted to support the crutch in a fully assembled mode, said foot section having an upper terminal end;
- and
- second means for detachably mounting said upper terminal end of said foot section to a lower terminal end of said lower midsection such that said lower midsection and said foot section are substantially axially aligned;
- whereby in said assembled mode, said head section, said upper and lower midsections, and said foot section define a substantially axially aligned support structure for said person and, in a collapsed mode, said head section, said upper and lower midsections, and said foot section form a compact assemblage.
