Claims (13)

1. An apparatus to assist a user in walking, comprising:

a first crutch having a first side direction, a second side direction opposite the first side direction, a third side direction perpendicular to the first side direction and a fourth side direction opposite the third side direction, the crutch comprising:

an elongate leg having a top end, a top portion, a middle portion, a bottom portion, and a bottom end, wherein the elongate leg extends from a saddle to a foot and has a handle disposed on the middle portion;

wherein the saddle has an elongate shape that extends in the first side direction;

wherein the top end of the elongate leg is pivotably attached to the saddle;

wherein the elongate leg middle portion is arced and disposed to the third side direction of an axis extending between the top end of the elongate leg and the foot;

wherein the elongate leg middle portion is also curved and extend outward to the first side direction of an axis extending between the top end of the elongate leg and the bottom end of the elongate leg; and

wherein the handle is cantilevered and has a fixed end attached to the middle portion of the elongate leg and a free end extending outward from the middle portion of the elongate legs.

2. The apparatus of claim 1 , wherein the first side direction is front.

3. The apparatus of claim 1 , wherein the top portion is adjustable with respect to the middle portion whereby the distance between the handle and the saddle may be changed.

4. The apparatus of claim 1 , wherein the bottom portion is adjustable with respect to the middle portion whereby the distance between the foot and the handle may be changed.

5. The apparatus of claim 1 , wherein the handle is cantilevered up such that when an axis extending between the top end of the leg and the bottom end of the leg is vertical, the free end of the handle is higher than the fixed end of the handle.

6. The apparatus of claim 1 , further comprising a second crutch that is in the mirror image of the first crutch.
