PURPOSE: A magnetic door closer is provided to strongly close a door using the repulsive force of two magnets and to easily open the strongly closed door. CONSTITUTION: A magnetic door closer uses two magnets(2). A door(5) is closed using repulsive force generated when the S pole or N pole of one magnet touches the S pole or N pole of the other magnet. If the door is a hinged door, the door is rotated around a hinge(4). A first ring with an angle between 90 to 270 degrees is formed on the hinge. A second ring with an angle between 0 to 90 degrees is attached to the door. |
