ABSTRACT:
A door closure system for one or more swinging doors includes, in its most basic form, a door closure assembly for a door pivotally mounted on a hinge axis in a door frame. The assembly includes a closure mechanism mounted on the door frame adjacent the door with a rotatable member extending therefrom, an elongated arm having a secured end fixed for rotation with a rotatable member and a free end extending alongside the door, and a roller wheel rotatably mounted on the free end of the arm and extending therefrom so as to overlap the door for engaging it and rolling about a wheel axis substantially parallel to the hinge axis when the door swings about the hinge axis from a first pivotal position to a second pivotal position. This door closure assembly can also be applied to a double swinging door by adding more closure mechanisms and interconnecting them for the desired synchronization. A stop for holding the door open to a set position can also be provided.
