Walkers and methods of use
View Patent ↗A walker having a folded position and an unfolded position, wherein the walker comprises a structural frame with a first upright portion, a second upright portion, a folding mechanism between the first upright portion and the second upright portion, ground engaging elements on each of the first upright portion and second upright portion, and a foldable basket with first and second opposed ends secured by one or more fasteners to the first upright portion and the second upright portion, respectively. In another embodiment, walker comprises a structural frame with a first end, a second end, and sides between the first end and the second end, a handle or handles on the structural frame at the first end of the structural frame, ground engaging elements at the first end and the second end of the structural frame, and a suspension system integrated with the structural frame.
1. A walker comprising:
a structural frame with a rear end, a front end, and sides between the rear end and the front end;
a handle or handles on the structural frame at the rear end of the structural frame;
rear ground engaging elements at the rear end of the structural frame;
front ground engaging elements at the front end of the structural frame;
a seat at the rear end of the structural frame;
lever arms, with each lever arm pivotally connected to a respective side of the structural frame at a pivot point that is below the seat, with each lever arm extended in a rearward direction from the pivot point to mount a respective rear ground engaging element a distance behind a rear end of the seat; and
a suspension system integrated with the structural frame, the suspension system comprising elements, with each element connected between the structural frame and a respective one of the lever arms, and with the elements being compressible to i) provide cushion and store energy when the weight of a user, sitting in the seat or leaning on the handle or handles, causes the pivot points to move in a downward direction, and ii) return the energy when unweighted by the user to cause the pivot point to move in an upward direction and provide a lift assist to the user.
2. The walker of claim 1 in which each element comprises a strut extended between the structural frame and the respective lever arm.
3. The walker of claim 2 in which the structural frame further comprises first and second upright portions that each define a respective side of the structural frame, extend to a respective handle, and are connected to a respective strut, and in which the structural frame further comprises a folding mechanism between the first and second upright portions to allow the first and second upright portions to fold towards and away from each other.
4. The walker of claim 3 in which the first and second upright portions each have a respective fork that mounts a respective front ground engaging element at the front end, have a first branch extended to the respective handle, and have a second branch pivotally connecting a respective lever arm.
5. The walker of claim 2 in which each strut is adjustable in stiffness.
6. A method of use of the walker of claim 1 .
7. The walker of claim 4 in which each second branch extends horizontally to the respective pivot point in use.
8. The walker of claim 1 in which each pivot point is located midway between a respective rear ground engaging element and a respective front ground engaging element.
9. The walker of claim 8 in which each pivot point is located midway between a front end of the seat and the rear end of the seat.
10. The walker of claim 1 in which the structural frame forms a rigid weight-bearing support between the front ground engaging elements and the handle or handles.
