Abstract:
An apparatus is provided for minimizing closing force of a door. The apparatus comprises a housing adapted to be disposed in the hinged edge of the door. A piston is slidably mounted in the bore. A button having an inner end and an outer end is disposed in the bore with the inner end of the button engaging the piston for urging the button toward a first extended position where the button extends from the edge of the door. The button is slidable in the bore relative to the housing for reciprocal movement between the extended position and a second position where the button is depressed into the bore against the force of the piston. The button is disposed so that the outer end of the button engages the door frame for slowing movement of the door in a closing direction as the button is moved into the bore to the depressed second position.
