IPC: E05C19/16
Filed: 1978-02-15
Abstract: PURPOSE: To provide an apparatus requiring no large force by smoothly separating a circular cylindrical magnet body from a retaining magnet body through gradual reduction in the mutual attraction force between the bodies.  
     CONSTITUTION: When a folding door is closed, in contact with a retaining magnet body 2, a circular cylindrical magnet body 8 retreats into a magnet retaining cylindrical hole 7, where they are mutually attracted as opposed to each other in different polarity. When the door is opened, the circular cylindrical magnet body 8 advances through the magnet retaining cylindrical hole 7 adhering to the receiving magnet body 2 even if the opening/closing end 6 moves in the opening direction of the door. At this point, engaged sliding with a rail groove 9, a slide projection 10 force the circular cylindrical magnet body 8 to turn and thus, the polarity of the two bodies is deviated from the previous position. With a gradual reduction in the mutual attraction force, the two bodies are separated from each other smoothly. Accordingly, any large instantaneous force can be eliminated in the opening direction of the door.
