Abstract

A door balancing system includes an adjustment block, a single adjustment screw, a first pulley system, and a second pulley system. The adjustment block includes a threaded orifice and mounts within a bearing housing that includes a bearing surface. The single adjustment screw threads into the threaded orifice and abuts the bearing surface. The first pulley system includes a first pulley, a first cable, and a first spring. The second pulley system includes a second pulley, a second cable, and a second spring. The first cable mounts between a first hinge and the adjustment block using the first pulley and the first spring. The second cable mounts between a second hinge and the adjustment block using the second pulley and the second spring. The first spring and the second spring exert a force on the door to control a rate of movement of the door relative to the body.
