Claims8
An automatically closed fire protection louver device installed on an outer surface of a wall or outside of a window WD, the louver device comprising:
- a control unit 300 including
- a main body 310 formed in a shape of a pipe having a front end hollow 313 and a rear end hollow 315, which are hollows, respectively formed at a front end and a rear end, in which a portion of a lower part is open to form a fuse room 311 connected to the front end hollow 313, and a plurality of control pins 360 is formed at an upper part in a row,
- a fuse 330 inserted in the fuse room 311 and broken by heat F at a predetermined temperature,
- a front side fixing rod 320 inserted in the front end hollow 313, having a rear end tightly attached to the fuse 330 and a front end exposed to outside of the front end hollow 313,
- a spring 340 inserted in the rear end hollow 315, and
- a rear side fixing rod 350 inserted in the rear end hollow 315, having a front end tightly attached to the spring 340 in a state of maintaining a compressive force of the spring 340 and a rear end exposed to outside of the rear end hollow 315;
- a plurality of blades 200 formed in a shape of a plate as a whole, in which each of the blades has a blade rotation axis 201 protruded at both ends, and a blade lower portion 220 is rested or hinge-coupled in a space between the control pins 360;
- and
- an exterior frame 100 configured of a front side plate 120 formed with a front side fixing rod insertion hole 122 at a center so that a front end of the front side fixing rod 320 may be inserted and fixed in the front side fixing rod insertion hole 122, a rear side plate 130 formed with a rear side fixing rod insertion hole 132 at a center so that a rear end of the rear side fixing rod 350 may be inserted and fixed in the rear side fixing rod insertion hole 132, and two side plates 110 respectively formed with a plurality of blade rotation axis insertion holes 111 at regular intervals in a row so that the blade rotation axis 201 may be inserted and rotated, in which both ends of each side plate are installed to be respectively attached to an end of the front side plate 120 and an end of the rear side plate 130, in which
- if heat F is applied to the fuse 330 when a fire breaks out, the fuse 330 is broken, and the main body 310 moves forward by the spring 340 so that the blade lower portion 220 rested or hinge-coupled in a space between the control pins 360 may move together with the main body 310, and thus the blade 200 is rotated and closed.
