Abstract
The swing control hinge disclosed is intended to control the rotational speed of a door that is tending to accelerate toward the strike as a result of spring loaded hinges. The hinge is intended to prevent slamming of the door while allowing enough speed to insure latching. The swing control hinge is housed in a hinge body that may be used as a third hinge. The hinge pin is made up of two cams that have cam parts on them which dissipate energy from conventional spring loaded hinges having helical spring or a block of rubber during the opening cycle of the door and the torsional force from the spring loaded hinges is dissipated in checking the door as it closes to keep the door from slamming.
