1. An articulated tripartite elbow-and-knee-area protector, comprising:
a flexible sleeve adapted to fit securely around the arm or leg at the elbow or knee joint and the adjacent areas, having proximal and distal ends and proximal and distal sides in relation to the person;
a proximal pad unit attached to said flexible sleeve at an attachment area on the distal side, near the joint, and running toward the proximal end;a distal pad unit attached to said flexible sleeve at an attachment area on the distal side, near the joint, and running toward the distal end;a joint pad unit having a convex top, extended portions and retracted portions on two opposite sides, and a concave bottom, attached to said flexible sleeve at an attachment area on the distal side, at the joint, between said proximal pad unit and distal pad unit; where said extended portions are arranged above said retracted portions and said retracted portions are adapted to define a void space to accommodate portions of said proximal pad unit and distal pad unit;
durable outer surfaces on said joint pad unit, proximal pad unit, and distal pad unit; unattached articulation areas between said attachment areas for said joint pad unit, proximal pad unit, and distal pad unit;
where said concave bottom is adapted to fit over the protruding joint when bent, said unattached articulation areas are adapted to provide the only points of bending along the line of said attachment areas; where the outward thrust of a bending joint lifts said joint pad unit and rotates said proximal pad unit and distal pad unit, all away from each other, where said extended portions protect said unattached articulation areas; and where said joint pad unit, proximal pad unit and distal pad unit resume an interleaved position upon the straightening of the joint. |
