Description
BACKGROUND OF THE
Generally, ventilation facilities are installed in apartment buildings and large buildings. These ventilation facilities prevent the spreading of fire in case of fire, ensuring the safety of evacuation, preventing loss by smoke, securing a watch for digestion, Means facilities for discharging.
Especially, as the number of high-rise apartment buildings and large buildings increases, the number of fire-generating elements increases so much that if people can not prevent spreading of flames and smoke when a fire occurs, people living in high- Because it causes many human loss and property loss, it is important to arrange the indoor space and the role of the fire door which acts as the door.
Such a fire door provides a time to evacuate the people when the fire occurs and prevents the fire from moving. In the smoke-free area where the smoke-free facility is installed, the door closes when smoke is detected by the smoke detector And the door can be closed instantly. For this purpose, the fire door is rotatably fixed to the door frame by the hinge device, so that the door opening / closing operation is possible.
The hinge device is configured such that each hinge element adapted to be rotated with respect to each other with the intermediate shaft-engaged portion interposed therebetween is configured to be coupled to the side surface of the door frame and the corresponding fire door, In particular, even when the fire door is closed, since the intermediate engaging part of the hinge device is always exposed to the outside, when the exposed part is disassembled or forcibly broken, the door can be forcibly opened even if the fire door is locked , So that even if a lock was installed in the fire door, the opening due to breakage of the exposed portion of the hinge element could not be prevented.
In addition, when the joint portion is exposed to the outside as in the conventional hinge device, the appearance is not good, and there is also a limit to making the door frame and the door cooperate with each other in the hinged door.
In order to solve the problems of the conventional exposure hinge device as described above, Korean Patent Registration No. 10-1206621 proposes an exposure hinge.
