PROBLEM TO BE SOLVED: To include a mechanism for suppressing excessive rotation of a winding shaft while the winding shaft is rewinding, in a screen device in which a slat is overlapped with a screen and wound by the winding shaft.SOLUTION: In a screen device with blind function, after a bottom bar 24 at a lower end of a screen 11 has reached a lower end of a screen frame by rewinding rotation of a winding shaft, by inverse winding of a slat operation member 12 to the winding shaft which is rewinding and rotating, opening rotation of the slat 13 starts. At a pass groove 18b of a guide part piece 25b of a second bottom bar 25 of a side frame 18 of the screen frame, a locking part 30 of a stopper part piece 27 is disposed which is inversely wound from the slat operation member 12, which is locked to the guide part piece 25b when upward movement of the second bottom bar 25 has reached an upper limit of the opening rotation of the slat, and suppresses any further upward movement of the second bottom bar. A mechanism is added for inactivating locking of the locking part 30, at a lifting stage of the bottom bar other than the bottom bars mentioned above.SELECTED DRAWING: Figure 4
【課題】巻取軸によりスクリーンにスラットが重ねて巻き取られるスクリーン装置において、巻取軸の巻き戻し回転時における該巻取軸の過回転を抑制する機構を備える。【解決手段】巻取軸の巻き戻し回転によりスクリーン１１の下端のボトムバー２４がスクリーン枠の下端に達した後に、巻き戻し回転する巻取軸へのスラット操作部材１２の逆巻きによりスラット１３の開回転が開始するブラインド機能付きスクリーン装置において、スクリーン枠の側枠１８の第２のボトムバー２５のガイド部片２５ｂの通溝１８ｂに、スラット操作部材１２の上記逆巻きで、第２のボトムバー２５の上動がスラットの開回転の上限に達したときに上記ガイド部片２５ｂに係止して、それ以上の第２のボトムバーの上動を抑止するストッパ部片２７の係止部３０を配設し、上記以外のボトムバーの昇降段階では、上記係止部３０の係止を不作動化する機構を付設する。【選択図】図４
