EMERGENCY DOOR DEVICE FOR FIREPROOF SCREEN SHUTTER
According to the present invention, disclosed is an improved emergency door device which is rolled up for a fireproof screen shutter, wherein an emergency door installed in a portion of a fireproof screen cloth is formed to be vertically operated, and when the emergency door is raised upwardly, the emergency door can be easily raised by a restoring force of a torsional spring to be quickly opened. Moreover, when power to raise the emergency door is removed, the emergency door is automatically closed to be conveniently used.
본 발명은 내화스크린천의 일부분에 설치된 비상문을 상하로 작동되도록 구성하되, 비상문을 상부로 들어올리면 비틀림스프링의 복원력에 의해 쉽게 들어 올려지면서 신속히 열리고 들어올렸던 힘을 제거하면 비상문이 자동으로 닫히도록 하여 편리하게 사용할 수 있도록 개선한 방화 스크린 셔터용 감아올리는 비상문장치를 개시한다.
