Double door stopper
This invention provides a double door stopper that, when switched to the emergency entry / exit function, can automatically correct the wedge-shaped gap between the magnetic surface and the fully open single door, thereby eliminating the gap and maintaining full contact, and thus maintaining the open door position. [Solution] The door stopper 10 has a buffer body 13 erected on the floor surface and a door stopper 20 has a magnet M and is slidably and rotatably mounted relative to the door stopper 10. The magnet M is elastically held so as to be able to swing horizontally via a horizontal axis 22 and an elastic body 23 connected to a rising surface portion 21b. The magnet M is positioned in front of the door stopper when emergency entry or exit occurs. If the positioning of the magnet M relative to the door D is inaccurate, and the magnet M makes contact with the fully open door D, resulting in a wedge-shaped gap between the magnet M and the door D, the magnet M has the function of tilting to eliminate the wedge-shaped gap due to the pressing force of the door D and making full contact with the door D.
