Biomechanically derived crutch

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;

a saddle attached to the top end of the elongate leg, wherein the elongate leg contacts the middle of the saddle with respect to the first side direction and the second side direction;

a foot attached to the bottom end of the elongate leg;

wherein the elongate leg extends from the saddle to the foot and has a handle disposed on the middle portion;

wherein the saddle extends in an elongate shape between the first side direction and the second side direction;

wherein the handle extends in an elongate shape;

wherein the handle is cantilevered and has a fixed end and a free end;

wherein the top portion is adjustable with respect to the middle portion whereby the distance between the handle and the saddle may be changed by telescopic insertion of the top portion into the middle portion; and

wherein the top portion is curved between the middle portion and the saddle;

wherein the elongate leg middle portion is disposed 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;

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

wherein the elongate leg middle portion has a bottom insertion point;

wherein the bottom portion is adjustable with respect to the middle portion whereby the distance between the foot and the handle may be changed by telescopic insertion of the bottom portion into the middle portion at the bottom insertion point; and

wherein the bottom insertion point is disposed to the first side direction of the axis extending between the top end of the elongate leg and the bottom end of the elongate leg; and

wherein the bottom insertion point is disposed to the third side direction of the axis extending between the top end of the elongate leg and the bottom end of the elongate leg.

2. The apparatus of claim 1 , wherein the bottom insertion point is disposed to the first side direction of the axis extending between the top end of the elongate leg and the bottom end of the elongate leg.

3. The apparatus of claim 1 , wherein the elongate leg is arced to the first side direction.

4. The apparatus of claim 1 , wherein the elongate leg is arced to the third side direction.

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

6. 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.

7. 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;

a saddle attached to the top end of the elongate leg;

a foot attached to the bottom end of the elongate leg;

wherein the elongate leg extends from the saddle to the foot and has a handle disposed on the middle portion;

wherein the saddle extends in an elongate shape between the first side direction and the second side direction;

wherein the saddle is pivotably connected to the elongate leg;

wherein the handle extends in an elongate shape;

wherein the handle is cantilevered and has a fixed end and a free end;

wherein the foot has a bottom surface, the bottom surface comprising:

a first continuous curve between the first side direction and the second side direction, and

a second continuous curve between the third side direction and the fourth side direction; and

wherein the second continuous curve is longer than the first continuous curve.

8. The apparatus of claim 7 , wherein the saddle is configured to allow vertical movement of the saddle with respect to the elongate leg in response to pressure.

9. The apparatus of claim 7 , further comprising a spring, wherein the saddle is configured to deform the spring in response to pressure placed on the saddle.

10. The apparatus of claim 7 , wherein the elongate leg middle portion is disposed 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.

11. The apparatus of claim 7 , wherein the elongate leg middle portion is disposed to the third side direction of an axis extending between the top end of the elongate leg and the bottom end of the elongate leg.

12. The apparatus of claim 7 , wherein the elongate leg is arced to the first side direction.

13. The apparatus of claim 7 , wherein the elongate leg is arced to the third side direction.

14. A crutch 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;

a saddle attached to the top end of the elongate leg;

a foot attached to the bottom end of the elongate leg;

wherein the elongate leg extends from the saddle to the foot and has a handle disposed on the middle portion;

wherein the saddle includes a frame member defining a central opening and a support membrane affixed to the frame and covering the central opening, the support membrane having an upper surface and a lower surface;

wherein the support membrane is tensioned across the central opening;

wherein the saddle comprises an inner lobe and an outer lobe, wherein the inner lobe is larger than the outer lobe.

15. The crutch of claim 14 wherein the frame member has a front curve and a back curve and wherein the support membrane is configured to follow the curves to provide a convex upper surface.
