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 (42)

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;

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;

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;

said lower portion further including a core and said upper portion further including a sleeve;

said core defining a locking channel configured to receive said locking pin;

said sleeve defining a locking aperture configured to receive said locking pin; and

said locking aperture and said locking channel being aligned when said core is adjacent said sleeve such that said locking pin is extendable therethrough.

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 , wherein said hinge assembly further comprises said locking pin.

4. The device of claim 3 , 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.

5. The device of claim 3 , 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.

6. The device of claim 5 , wherein:

said core extends along a longitudinal axis of said lower member; and

said sleeve extends along a longitudinal axis of said upper member, said sleeve being configured to pivotally receive said core through said opening.

7. 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.

8. The walker device of claim 1 , further comprising a handlebar configured for being gripped by the individual.

9. The device of claim 1 , wherein said second end of said first rear leg is rotatably connected to said first front leg.

10. 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.

11. The device of claim 10 , 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.

12. The device of claim 11 , 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.

13. The device of claim 12 , further comprising a backrest disposed between said first front leg and said second front leg.

14. A device for assisting an individual with mobility, comprising:

a first front leg including a first end and a second end;

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 and said lower member being pivotal between an extended use position and folded storage position;

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;

said hinge assembly further including 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;

said locking pin further including a first end, a second end, and a button disposed on said 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;

said lower portion further including a core, said core extending along a longitudinal axis of said lower member;

said upper portion further including 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; and

said core defining a locking channel configured to receive said locking pin;

said sleeve defining a locking aperture configured to receive said locking pin; and

said locking aperture and said locking channel being aligned when said core is adjacent said sleeve such that said locking pin is extendable therethrough.
