Abstract

PURPOSE: To further improve close contact, and easily perform opening and closing by utilizing an electromagnetic control mechanism in a system to bring the door into close contact with the door frame of a main entrance, a furniture or the like by means of magnetic force.
CONSTITUTION: In the state where a door 1 is closed, a latch bolt 5 and a frame body 2 are fitted, a lead switch 9 and an electromagnet 7 are in an off state, and the attraction force of the door 1 and the frame body 2 acts on by a magnetic body. Next, when a knob 4 is rotated, fitting of the latch bolt 5 and the frame body 2 comes off, the lead switch is turned on, the electromagnet 7 is operated to produce repulsion, resist against the magnetic body 3, and the attraction force of the door 1 and the frame body 2 is reduced. Furthermore, when the knob 4 is pulled, door opening is easily performed by slight force.
