OPENING/CLOSING DEVICE FOR PROJECTING WINDOW
PROBLEM TO BE SOLVED: To provide an opening/closing device for a projecting window that inclines to an appropriate angle fit for window pressure and allows a shoji screen to be opened for certain to a prescribed smoke exhausting posture.SOLUTION: A projecting window 1 of the present invention includes a shoji screen 4 inside a window frame 3, the shoji screen being opened in an inclined state by having an upper part of the shoji screen 4 lowered and a lower part of the shoji scree 4 separated from the window frame 3. An opening/closing device 13 of the projecting window 1 includes: an inclination restricting bracket 20 protruding from the shoji screen 4; an opening/closing bracket 22 supported on a vertical base 16 in a way that allows lifting and lowering, and receiving a lower edge side of an opening/closing roller 19 of the inclination restricting bracket 20; a handle box 12 and a tensile spring 26 for lifting/lowering the opening/closing bracket 22; and a pressing bracket 24 in contact with an upper edge side of the opening/closing roller 19, to be lifted/lowered along with the inclination restricting bracket 20. The opening/closing bracket 22 presses down the pressing bracket 24 when the shoji screen 4 is changing an attitude toward a closing direction.SELECTED DRAWING: Figure 1
【課題】風圧に応じた適正な角度に傾斜するうえに、障子を所定の排煙姿勢まで確実に開かせることができる辷り出し窓の開閉装置を提供する。【解決手段】本発明に係る辷り出し窓１は、窓枠３内の障子４の上部が下降するとともに障子４の下部が窓枠３から離れることで障子４が傾斜状に開かれる。辷り出し窓１の開閉装置１３は、障子４から突出する傾斜規制用ブラケット２０と、縦ベース１６に昇降移動可能に支持されて傾斜規制用ブラケット２０の開閉用ローラ１９の下端側を受け止める開閉用ブラケット２２と、開閉用ブラケット２２を昇降させるハンドルボックス１２および引っ張りバネ２６と、前記開閉用ローラ１９の上端側に当接していて傾斜規制用ブラケット２０と共に昇降可能になっている押圧用ブラケット２４を有する。開閉用ブラケット２２は、障子４が閉じ方向側へ姿勢変更している場合に押圧用ブラケット２４を押し下げる。【選択図】 図１
