Knee brace improvement

摘要

This invention is an elastic mechanism that extends and retracts during motions of the knee so that it maintains tension in a generally rearward direction on the area of the head of the tibia throughout the range of motion of the knee. The structure is anchored to a stable superior part of the body, above a height of contour, by an attachment which can be a belt, girdle, garment, suspenders or a combination of these attachments. The elastic mechanism attaches inferiorly to a number of connection mechanisms which connect to both sides of a hinged rigid knee brace near the tibial head, below the hinges of the knee brace.

主权项

1. An improvement for a hinged rigid knee brace comprising:
the hinged rigid knee brace comprising an upper rigid portion adapted to be attached to a thigh of a wearer; a lower rigid portion adapted to be attached to a calf of the wearer; a hinge on a left side of the hinged rigid knee brace; and a hinge on a right side of the hinged rigid knee brace, the hinges connecting the upper and lower rigid portions; a belt configured to be worn above the waist of the wearer; and an elastic mechanism, the elastic mechanism being attached at a first end to a back end of the belt and attached at a second end to connection mechanisms that flexibly connect the elastic mechanism to both the left and right sides of the hinged rigid knee brace below the hinges; wherein the elastic mechanism stretches and retracts throughout hinging motion of the hinged rigid knee brace, maintaining tension in a rearward direction upon the lower rigid portion of the hinged rigid knee brace near the hinges.
