FIREPROOF PLANAR LATTICE

Title:

FIREPROOF PLANAR LATTICE

Document Type and Number:

Japanese Patent JP2023010114

Kind Code:

A

Abstract:

To achieve a structure of a fireproof planar lattice which can prevent heat radiation from a window device from being shielded, even in the case where a fire occurs indoors, in a state of a louver being totally closed.SOLUTION: A fireproof planar lattice 1 includes a planar lattice body 14, a window frame side bracket 15, and a lock device 16. The planar lattice body 14 is openably/closably mounted on the outdoor side of a window vertical frame constituting a window device 2 by utilizing the window frame side bracket 15. In a normal situation, by the lock device 16 mounted between the window vertical frame and the planar lattice body 14, the planar lattice body 14 is locked to a closed position, and when a fire occurs, a release mechanism included in the lock device 16 is actuated and lock is released. Thereby, the planar lattice body 14 is oscillated and opened.SELECTED DRAWING: Figure 9
