Abstract

A mobility device includes at least a first front leg and at least a first rear leg connected to the first front leg. The first rear leg includes an upper member having a first end and a second end and a lower member having a first end and a second end. The first end of the upper member is pivotally connected to the first end of the lower member, and the lower member is preferably pivotal between an extended use position and a folded storage position.

Claims (20)

1. A device for assisting an individual with mobility, comprising:
a first front leg including a first end and a second end; and a first rear leg connected to said first front leg, said first rear leg including an upper member having a first end and a second end, a lower member having a first end and a second end, said first end of said upper member being pivotally connected to said first end of said lower member.
2. The device of claim 1, wherein said lower member is pivotal between an extended use position and a folded storage position.
3. The device of claim 2, further comprising a hinge assembly including an upper portion connected to said first end of said upper member, a lower portion connected to said first end of said lower member, and an axle pivotally connecting said upper and said lower portions.
4. The device of claim 3, wherein said hinge assembly further comprises a locking pin configured to extend through both said upper portion and said lower portion such that said lower member is secured in said extended use position.
5. The device of claim 4, wherein said locking pin further comprises a first end, a second end, and a button disposed on the first end, said button being configured such that urging said button away from said hinge assembly disengages said second end from said lower portion, thereby allowing said lower portion to rotate about said axle.
6. The device of claim 4, wherein said locking pin further comprises a first end, a second end, and a button disposed on the first end, said button being configured such that urging said button away from said hinge assembly disengages said second end from said upper portion, thereby allowing said lower portion to pivot about said axle.
7. The device of claim 6, wherein:
said lower portion further includes a core, said core extending along a longitudinal axis of said lower member; and said upper portion further includes a sleeve defining an opening, said sleeve extending along a longitudinal axis of said upper member, said sleeve being configured to pivotally receive said core through said opening.
8. The device of claim 7, wherein:
said core defines a locking channel configured to receive said locking pin;
said sleeve defines a locking aperture configured to receive said locking pin;
and wherein said locking aperture and said locking channel are aligned when said core is adjacent said sleeve such that said locking pin is extendable therethrough.
9. The device of claim 1, further comprising:
a first front wheel assembly connected to said second end of said first front leg;
and a first rear wheel assembly connected to said second end of said lower member of said first rear leg.
10. The walker device of claim 1, further comprising a handlebar configured for being gripped by the individual.
11. The device of claim 1, further comprising:
a second front leg including a first and a second end;
a second rear leg connected to said second front leg, said second rear leg including an upper member having a first end and a second end, a lower member having a first end and a second end, said first end of said upper member being pivotally connected to said first end of said lower member;
a first cross member connecting said first front leg and said second front leg; and a second cross member connecting said upper member of said first rear leg to said upper member of said second rear leg.
12. The device of claim 11, further comprising:
a front wheel assembly disposed on each of said first and second front legs;
and a rear wheel assembly disposed on each of said first and second rear legs.
13 13. The device of claim 12, further comprising a seat, wherein said first cross member and said second cross member are parallel and equidistant from a support surface beneath said walker device, and said seat is supported by said first cross member and said second cross member.
14. The device of claim 13, further comprising a backrest disposed between said first front leg and said second front leg.
15. The device of claim 1, wherein said second end of said first rear leg is rotatably connected to said first front leg.
16. A walker device for assisting an individual to walk, comprising:
a first front leg, a second front leg, and a first cross-member, each of said first and second front legs including a first end and a second end, said first cross-member connecting said first and second front legs;
a first rear leg connected to said first front leg, said first rear leg including an upper member having a first end and a second end, a lower member having a first end and a second end, and means for hingably connecting said first end of said upper member to said first end of said lower member;
a second rear leg connected to said second front leg, said second rear leg including an upper member having a first end and a second end, a lower member having a first end and a second end, and means for hingably connecting said first end of said upper member to said first end of said lower member; and wherein said lower members of said first and second rear legs are pivotal between an extended use position and a folded storage position.
17. The walker device of claim 16, further comprising means for rotatably connecting said second ends of said upper members of said first and second rear legs to said first and second front legs, respectively
18. The walker device of claim 16, further comprising means for rotatingly transporting said walker device along a support surface, said means for rotatingly transporting being disposed on said second ends of said first front leg, said second front leg, and said lower members of said first and second rear legs.
19. The walker device of claim 16, wherein said means for rotatingly transporting further comprises a plurality of wheel assemblies.
20. A walker device for assisting an individual to walk, comprising:
a first front leg including a first end and a second end, a second front leg including a first end and a second end, and a first cross-member connecting said first and second front legs;
a first handlebar disposed on said first end of said first front leg, a second handlebar disposed on said first end of said second front leg, said first and second handlebars being configured for being gripped by the individual;
a first rear leg connected to said first front leg, said first rear leg including an upper member having a first end and a second end, a lower member having a first end and a second end, said first end of said upper member being pivotally connected to said first end of said lower member;
