ABSTRACT:
A door closer assembly provides a closing force to a door swingably mounted on a door jamb by a pair of arms pivotally attached to the door and the door frame. The door closer assembly has a housing and a spring for providing a closing force on the arm which closes the door when it is an open position. The improvement of the present invention includes a spring cushion device mounted on the housing of the door closer assembly for stopping the opening movement of the door as it reaches a predetermined angle of rotation. The cushion device provides a resilient counteracting force on the arm as the door reaches its predetermined angle of rotation which lessens the wear and tear exerted on the assembly by the opening force of the door.
