Abstract
A first and second pair of door stop elements are mounted to an existing door hinge and aligned with the barrels on the door hinge. A pair of barrels have to be cutaway to mount the stops. The hinge pin holds everything in position. One of the pair of door stops is shaped like a metal bar with a pair of knuckles at the top and the bottom. It also has curves, indentations, flat contact points and grooves. The back of the first stop is recessed to provide clearance to avoid the hinge barrels against which the stop is positioned after installation. The flat contact points abut against the faces of the pair of door hinges to prevent the door from opening beyond a fixed point. The fist stop is used alone when the door opens up to 180 degrees. The second stop works with the first stop element and is used to limit the door opening to much less than 180 degrees. The second element is described as an elongated U-shaped bracket. The first element fits inside the second element. Both elements pivot freely about the hinge pin. The second element has a pair of screws to adjust and limit the opening angle of the door. Variants of the invention are elongated versions of the first and second stop elements. The variants fit at the top and bottom of a conventional door hinge. An elongated hinge pin and a nut are necessary to mount the elongated version to the pair of door hinges.
