ABSTRACT:
Gravity-actuated self-closing hardware adapted to be attached to a closure, such as a door, for mounting swingably the door to a door frame to enable the door to swing between an open position out of the plane of the door frame and a closed position disposed within the plane of the door frame, includes an upper universal mounting device adapted to mount the top edge of the door at one of the top corner portions thereof to the door frame to support swingably and universally the door from the frame about a point disposed within the plane of the door frame so that the door disposed normally at rest in the closed position can swing out of the plane of the door frame and the lower portion of the door can tilt upwardly, and a lower universal mounting device adapted to mount the side edge of the door near the bottom edge thereof below the upper device to the adjacent portion of the door frame to cause the lower portion of the door to swing about a point outside of the plane of the door frame and to cause the lower portion of the door to tilt upwardly as the door swings open. After the door is pulled to its open position, it may be released to permit the door to fall under the force of gravity and to swing about the lower and upper devices from its open position to its closed position without the need for separate door closing mechanisms.
