Patent ID: 8864188

Claim:
A door closure system which includes: a door having two planar parallel faces and four planar edges each perpendicular to the faces; a door frame; a first and second magnetic assembly, each of said first and second magnetic assemblies comprising: a magnet having a central axis; and a housing in which the respective magnet is housed; and wherein the door is hinged to the door frame, and the door frame has at least one abutting surface that the door abuts when the door is in a closed position; wherein at least one of the first and second magnetic assemblies of the door closure system includes an adjustment mechanism to adjust the position of the magnet relative to its housing, wherein the first magnetic assembly is mounted within a top edge of the door or a side edge of the door, the second magnetic assembly is mounted within the door frame, and, the first magnetic assembly is adjacent but not in contact with the second magnetic assembly when the door abuts the abutting surface of the door frame; and wherein the central axis of the magnet in the first magnetic assembly is aligned substantially perpendicular to the edge of the door within which the first magnetic assembly is mounted; and wherein, when the door abuts the abutting surface of the door frame, the central axis of the magnet in the second magnetic assembly is aligned substantially parallel to the central axis of the magnet in the first magnetic assembly wherein, when the door abuts the abutting surface of the door frame, the central axis of the magnet in the second magnetic assembly is spaced from the central axis of the magnet in the first magnetic assembly in a direction substantially perpendicular to the planar faces of the door and towards the abutting surface of the door frame, such that when the door is closed, the second magnetic assembly exerts an attractive force on the first magnetic assembly in the direction substantially perpendicular to the planar faces of the door and towards the abutting surface of the door frame.
