OPENING/CLOSING DIRECTION RESTRICTING MECHANISM FOR MANUAL SHUTTER DEVICE, AND OPENING/CLOSING DIRECTION RESTRICTING MECHANISM FOR SUSPENDED SLIDING DOOR DEVICE
PROBLEM TO BE SOLVED: To provide an opening/closing direction restricting mechanism for a manual shutter device and an opening/closing direction restricting mechanism for a suspended sliding door that enable at a low cost a mechanism for positioning an operation member that moves relative to a fixed member at a desired position.SOLUTION: An opening/closing direction restricting mechanism 10 includes: a flange 11 fastened on a fixed axis 4; a bracket 12 loosely fit on the fixed axis 4 and rotatable integrally with a winding member 3; and a two-way clutch 13 that may be switched between a reversed rotation blocking state and a normal rotation blocking state, the reversed rotation blocking state permitting revolution of a planetary external gear 13b for the clutch in a winding direction D1 of the winding member 3 while blocking the revolution of the planetary external gear 13b in an unwinding direction D2, and the normal rotation blocking state blocking the revolution of the planetary external gear 13b for the clutch in the winding direction D1 of the winding member 3 while permitting the revolution of the planetary external gear 13b for the clutch in the unwinding direction D2.SELECTED DRAWING: Figure 2
【課題】固定部材に対して相対的に移動する作動部材を所望の位置に位置決めする機構を低コストで実現可能な手動式シャッター装置の開閉方向規制機構及び吊引戸の開閉方向規制機構を提供する。【解決手段】固定軸４に固着されたフランジ１１と、固定軸４に遊嵌されると共に巻取部材３と一体で回転可能なブラケット１２と、巻取部材３の巻取方向Ｄ１に沿ったクラッチ用遊星外歯車１３ｂの公転を許容して反巻取方向Ｄ２に沿ったクラッチ用遊星外歯車１３ｂの公転を阻止する逆転阻止状態と、巻取部材３の巻取方向Ｄ１に沿ったクラッチ用遊星外歯車１３ｂの公転を阻止して反巻取方向Ｄ２に沿ったクラッチ用遊星外歯車１３ｂの公転を許容する正転阻止状態とを切換自在な２ウェイクラッチ１３と、を備えている開閉方向規制機構１０。【選択図】図２
