AUTOMATIC CLOSING APPARATUS FOR FIRE DOOR
The present invention relates to an automatic closing device for a fire door, which is installed on the fire door in a smoke control area formed on each floor of a building, and restricts the fire door in an open state in a normal situation, but automatically locks the fire door by a closing force provided from a door closer by releasing a state of restriction in case of fire. More specifically, the automatic closing device for a fire door comprises: a main body; a rotary shaft installed on the main body; a link arm whose one end part is fixed to the rotary shaft to be rotated with respect to the rotary shaft, and which connects the rotary shaft and a link arm of a door closer; and a restriction part which restricts the rotary shaft interlocked with the link arm of the door closer through the link arm.
본 발명은 방화문용 자동 폐쇄장치에 관한 것으로, 더욱 상세하게는 건축물의 각 층에 형성된 제연구역의 방화문에 설치되어, 평상시에는 개방된 방화문을 개방된 상태로 구속하고 화재 발생시에는 구속상태를 해제시켜 도어 클로저에서 제공되는 폐쇄력에 의해 방화문을 자동 잠금하는 방화문용 자동 폐쇄장치에 관한 것이다.
