Biomechanically derived crutch

摘要

A 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 including 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 extends in an elongate shape between the first side direction and the second side direction, wherein the handle extends in an elongate shape between the first side direction and the second side direction, wherein the elongate leg middle portion is to the third side direction of an axis extending between the leg and the foot, wherein the elongate leg middle portion is 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 and a free end.

主权项

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.
