Abstract
Abstract A knee brace is disclosed which closely simulates the rockinghinge joint motion and sliding motion of a knee. The knee brace is comprised of an upper rigid body and a lower rigid body, each having legs pivotably coupled together in a manner so that the legs may pivot relative to each other about an axis generally perpendicular to the zone of overlap and may slide relative to each other in all radial directions generally parallel to the zone of overlap. In one embodiment, the legs may also pivot toward and away from one another. The knee brace may be worn under the pants of the wearer who may run, walk, or sit down without giving any indication that he is wearing a knee brace.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
A knee brace comprising a stiff upper body for encircling a substantial portion of the thigh, said upper body having a downwardly extending leg adapted to extend along the medial cartilage or ligaments of the knee joint, a stiff lower body for encircling a substantial portion of a calf, said lower body having an upwardly extending leg which overlies said upper leg, hinge means joining said legs so that the legs may slide in all radial directions generally parallel to their zone of overlap and pivot with respect to each other about an axis generally perpendicular to their zone of overlap, said hinge means including a grommet on one leg, a rivetlike member having a shank extending through the grommet, the inner diameter of the grommet being at least twice the diameter of the shank.
Claim 2
Dependent Claim
135 words
A knee brace comprising a stiff upper body for encircling a substantial portion of the thigh, said upper body having a downwardly extending leg adapted to extend along the medial cartilage or ligaments of the knee joint, a stiff lower body for encircling a substantial portion of a calf, said lower body having an upwardly extending leg which overlies said upper leg, hinge means joining said legs so that the legs may slide in all radial directions generally parallel to their zone of overlap and pivot with respect to each other about an axis generally perpendicular to their zone of overlap, said hinge means including a grommet on one leg, a rivetlike member having a shank extending through the grommet, the inner diameter of the grommet being at least twice the diameter of the shank.
Claim 3
Dependent Claim
45 words
A knee brace in accordance with claim 1 wherein said upper and lower bodies are made from a rigid polymeric plastic material, and a free end of each strip of flexible material being releasably coupled at an area juxtaposed to a surface of said bodies.
Claim 4
Dependent Claim
20 words
A knee brace in accordance with claim 1 wherein said upwardly extending leg is metal coated with a polymeric plastic.
Claim 5
Dependent Claim
26 words
A knee brace in accordance with claim 1 wherein one of said bodies has an end disposed within a pocket on the flexible material associated therewith.
Claim 6
Dependent Claim
33 words
A knee brace in accordance with claim 1 including a rubber lining on each body, and each of said strips of flexible material being elastomeric, and said bodies being made from a polycarbonate.
Claim 7
Dependent Claim
35 words
A knee brace in accordance with claim 4 wherein each body has a portion disposed within a pocket on each strip of flexible material for ease of assembly and replacement of the strips of material.
Claim 8
Dependent Claim
171 words
A knee brace comprising an upper body for encircling at least a substantial portion of a thigh, said upper body having a connecting portion adapted to extend along the medial cartilage or ligaments of the knee joint, a lower body for encircling at least a substantial portion of a calf, said lower body having a connecting portion which overlies said upper body connecting portion, hinge means joining said connecting portions so that they May slide in all radial directions generally parallel to their zone of overlap and pivot with respect to each other about an axis generally perpendicular to their zone of overlap, said hinge means including a grommet on one connecting portion, a pin having its shank extending through the grommet, the inner diameter of the grommet being at least twice the diameter of the shank so that the connecting portions may slide in all radial directions until said shank contacts the inner surface of said grommet, and said connecting portions being pivotable about the longitudinal axis of said pin.
Claim 9
Dependent Claim
171 words
A knee brace comprising an upper body for encircling at least a substantial portion of a thigh, said upper body having a connecting portion adapted to extend along the medial cartilage or ligaments of the knee joint, a lower body for encircling at least a substantial portion of a calf, said lower body having a connecting portion which overlies said upper body connecting portion, hinge means joining said connecting portions so that they May slide in all radial directions generally parallel to their zone of overlap and pivot with respect to each other about an axis generally perpendicular to their zone of overlap, said hinge means including a grommet on one connecting portion, a pin having its shank extending through the grommet, the inner diameter of the grommet being at least twice the diameter of the shank so that the connecting portions may slide in all radial directions until said shank contacts the inner surface of said grommet, and said connecting portions being pivotable about the longitudinal axis of said pin.
