Abstract:
An artificial knee is configured to be worn by a person. Artificial knees include a thigh link configured to move in unison with a thigh of the person, and a shank link configured to be coupled to the thigh link. Artificial knees include a compression spring coupled to the thigh link at a first end of the compression spring, the compression spring configured to be coupled to the shank link at a second end of the compression spring. The compression spring is configured to provide an extension torque between the thigh link and the shank link during a first range of motion of the thigh link and the shank link relative to each other. The compression spring is configured to provide a flexion torque between the thigh link and the shank link during a second range of motion of the thigh link and the shank link relative to each other.

Claim (Index 13):
An artificial knee configured to be worn by a person, the artificial knee comprising:\n a thigh link configured to move in unison with a thigh of the person; a shank link configured to move in unison with a shank of the person, the shank link being rotatably coupled to the thigh link; a compression spring rotatably coupled to the thigh link from a first end of the compression spring, the compression spring being rotatably coupled to the shank link from a second end of the compression spring; a follower link rotatably coupled to the second end of the compression spring from a first end of the follower link, the follower link being rotatably coupled to the shank link from a second end of the follower link such that the thigh link, the shank link, the follower link, and the compression spring form a four bar linkage; and a constraint configured to constrain a motion of the follower link relative to the shank link near a singular point, wherein the singular point is a point where the compression spring and the follower link are in line with each other, wherein when the follower link is moved from the singular point toward the constraint, the constraint is configured to constrain the follower link, and the compression spring is configured to generate a force such that the force passes through a joint of the artificial knee during a range of motion of the thigh link relative to the shank link.
