FIREPROOF OPENING AND CLOSING DEVICE
To provide a fireproof opening and closing device capable of preventing the reduction in operability of the fireproof opening and closing device as well as suppressing enlargement of a size of a housing box, limitation of a place to be installed, and disfigurement of an opening of a building by avoiding lengthening a roll diameter at an end side in a width direction of a screen even with a stopper for preventing the sheet screen from falling off from a guide frame.SOLUTION: A stopper 51, provided at an end part in a width direction surrounded by left and right guide frames, of a screen 5 whose end in the width direction is surrounded by the left and right guide frames and which is wound and unwound along the left and right guide frames is formed by a thread made of a fireproof material.SELECTED DRAWING: Figure 3
【課題】シート状のスクリーンがガイド枠から抜けることを防止する抜止部を設けても、スクリーンの幅方向端部側の巻き径が大きくなることを抑制することで、収容ボックスの大型化、設置可能な場所の制限、及び、建物の開口部の美観の低下を抑制しつつ、防火用開閉装置の操作性の低下を抑制可能な防火用開閉装置を提供する。【解決手段】幅方向の端部が前記左右ガイド枠に囲まれ、且つ、前記左右ガイド枠に沿って巻取り及び巻戻しされるスクリーン５の、左右ガイド枠に囲まれる幅方向端部に形成される抜止部５１を、不燃材料からなる糸により構成する。【選択図】図３
