Dual-hinge mechanism and related methods

Abstract

The present invention provides a mechanism for mounting a door comprising a dual-hinge or “double-knuckle” spine/hinge system which allows a traffic door to open a full 180 degrees in both directions from a closed position. The mechanism allows the door to be flush with a wall that is adjacent to the door resulting in minimal obstruction of hallways and/or other traffic areas into which the door opens, thereby significantly increasing the efficient use of limited space. The present invention also provides a mechanism for cushioning a door against sudden impacts and reducing the stresses from loads that are commonly placed on the door and jamb due to frequent opening and closing.
