AUTOMATIC CLOSING LOUVER DEVICE FOR FIRE PROTECTION

摘要

Disclosed is an automatic closing louver device for fire protection including: a controller having a front surface fixing bar, a rear surface fixing bar, a body open at the lower portion thereof and having a fuse chamber formed at the inside of the lower portion thereof, and an elastic body; plate-like blades each having a blade rotating shaft protrudedly formed on both ends thereof and a lower portion rotatably coupled to the top portion of the body by means of hinge parts; and an outer frame having a front surface plate, a rear surface plate, and two side surface plates, wherein if flames come into contact with the fuse, the fuse is broken and the coupled portion between the rear surface fixing bar and the body moves forwardly by means of the elastic body, so that the blades are rotated and closed to form a fire protection wall.

1. An automatic closing louver device for fire protection installed on an outer wall surface or on the outside of a window WD, the automatic closing louver device comprising:
a controller 300 having a front surface fixing bar 320 having protrusions 322 formed on both sides of the rear end thereof, a rear surface fixing bar 340 having protrusions 342 formed on both sides of the front end thereof, a body 310 open at the lower portion thereof and having a fuse chamber 311 formed at the inside of the lower portion thereof so as to insertedly mount a fuse 330 thereinto and slots 312 and protrusion coupling portions 313 formed on both side surfaces thereof, and an elastic body 350 adapted to provide a driving force thereto; a plurality of plate-like blades 200 each having a blade rotating shaft 201 protrudedly formed on both ends thereof and a lower portion 220 rotatably coupled to the top portion of the body 310 by means of hinge parts 202, 202′ and 203; and an outer frame 100 having a front surface plate 120 having a front surface fixing bar insertion hole 122 formed at the center thereof so as to insert the front end of the front surface fixing bar 320 thereinto, a rear surface plate 130 having a rear surface fixing bar insertion hole 132 formed at the center thereof so as to insert the rear end of the rear surface fixing bar 340 together with the elastic body 350 thereinto, and two side surface plates 110 each having a plurality of blade rotating shaft insertion holes 111 equally spaced apart from each other so as to insert and rotate the blade rotating shafts 201 and attached to both ends of the front surface plate 120 and the rear surface plate 130 on the front and rear ends thereof, wherein the protrusions 322 and the protrusions 342 are coupled correspondingly to the slots 312 and the protrusion coupling portions 313, and in the state where the protrusions 322 are located at the front ends of the slots 312 and the fuse 330 is located in the fuse chamber 330 between the rear end of the front surface fixing bar 320 and the front end of the rear surface fixing bar 340, if flames F come into contact with the fuse 330 when a fire breaks out, the fuse 330 is broken and the coupled portion between the rear surface fixing bar 340 and the body 310 moves forwardly by means of the elastic body 350, so that the blades 200 are rotated and closed to form a fire protection wall.
