Patent ID: 8720458

Claim:
A tubular crutch comprising: a tubular crutch body that includes, a tubular posterior stabilizing element having a tubular posterior stabilizing element center line, a first concave curve adjacent to the posterior stabilizing element, wherein the first concave curve has a first angle of approximately 75°-85°; a second convex curve proximate to the first concave curve, wherein the second convex curve has a second angle of approximately 152°-162°; a third concave curve proximate to the second convex curve, wherein the third concave curve has a third angle of approximately 56.5°-66.5°, the first concave curve, the second convex curve, the third concave curve in a first plane, a tubular elongated portion adjacent to the third concave curve, the tubular elongated portion having a first plurality of paired orifices in the first plane and a second plurality of orifices at a second plane at a bottom of the tubular elongated portion; the tubular elongated portion having a tubular elongated portion center line that is 10°-20° from the tubular posterior stabilizing element center line; and a cantilever handle that includes, a curved base plate configured to interface with the tubular elongated portion, the curved base plate having a base plate orifice, a bolt having a threaded end and a head end, wherein the head end is fixedly coupled to the curved base plate and the threaded end of the bolt extends through the base plate orifice and extends at a 90° angle from the curved base plate, a tubular member having one end fixedly coupled to a convex side of the curved base plate, the tubular member configured to extend into the first plane at approximately 75°-80° degrees from the curved base plate, the bolt configured to pass through one of the first plurality of paired orifices, a nut configured to receive the threaded end of the bolt, and a contoured component configured to ergonomically interface with a palm of a hand; and a ground engaging extension that includes a spring loaded button that is configured to be received by at least one of the second plurality of orifices at the bottom of the tubular elongated member.
