SCREEN SHUTTER
PROBLEM TO BE SOLVED: To provide a screen shutter that offers high air-tightness, heat insulation property and sound insulation property when a screen is closed, as both side edges of the screen come in contact with a vertical casing, and prevents damaging of the screen caused by abrasion with the vertical casing when the screen is opened/closed, as a gap is formed between the screen and the vertical casing.SOLUTION: A flexible bottom rail 6 is suspended by lifting cords 41, 42 inserted into a part close to both side edges of a screen 3 and at an intermediate part. A differential motion mechanism provided on a take-up device 7 of the lifting cords 41, 42 causes the lifting cord 42 at the intermediate part to be delivered ahead of the lifting cord 41 near both side edges while the screen 3 is being lifted/lowered. Thus, the bottom rail 6 is lifted/lowered in a curved state protruding downward.SELECTED DRAWING: Figure 3
【課題】スクリーンを閉じた状態では、スクリーンの両側縁が縦額縁に当接して高い気密性、断熱性、遮音性が得られ、スクリーンの開閉操作時には、スクリーンと縦額縁との間に隙間が生じて、縦額縁との擦過によるスクリーンの損傷が防止される。【解決手段】スクリーン３の両側縁近傍と中間部に挿通された昇降コード４１、４２によって可撓性を有するボトムレール６が吊持されるとともに、昇降コード４１、４２の巻取装置７に設けられた差動機構により、スクリーン３の昇降時に中間部の昇降コード４２が両側縁近傍の昇降コード４１よりも先行して繰り出されることで、ボトムレール６が下向きに凸となるように湾曲した状態で昇降する。【選択図】 図３
