MOVABLE LOUVER SURFACE LATTICE AND FITTING HAVING THE SAME
To provide a movable louver surface lattice excellent in fire prevention capable of preventing occurrence of inconvenience that the flame shielding performance of a glass window is deteriorated due to heat radiation from the glass surface of the glass window being hardly transmitted to the periphery of a temperature sensor in a case of a fire break-out on the indoor side.SOLUTION: A movable louver surface lattice, which has a plurality of openable and closable louvers 23, 33 and installed on the outdoor side of a glass window 2, includes a shielding ratio reduction mechanism 60 for reducing the shielding ratio by the plurality of louvers 23, 33 when the louvers 23,33 in the opening direction, and a temperature sensor S for operating the shielding ratio reduction mechanism 60 when the ambient temperature reaches a specified temperature, the temperature sensor S being arranged at a position facing the glass surface of the glass window 2.SELECTED DRAWING: Figure 1
【課題】室内側で火災が発生した場合に、ガラス窓のガラス面からの放熱が温度センサの周囲に伝わり難いことに起因してガラス窓の遮炎性能が低下する不都合の発生を防止することができる、防火性に優れた可動ルーバー面格子を提供する。【解決手段】開閉可能な複数のルーバー２３，３３を有してガラス窓２の室外側に設置される可動ルーバー面格子において、ルーバー２３，３３を開方向に揺動させて複数のルーバー２３，３３による遮蔽率を低減させる遮蔽率低減機構６０と、周囲温度が所定温度に達するのに伴って遮蔽率低減機構６０を作動させる温度センサＳとが備えられ、温度センサＳが、ガラス窓２のガラス面に対向する部位に配置されている。【選択図】図１
