BLIND DRIVING GEAR
PROBLEM TO BE SOLVED: To provide a blind driving gear capable of preventing a stopper from being damaged even when an excessive torque is applied to a rotation axis while allowing the stopper to be released other than in ordinary operation.SOLUTION: A driving gear 100 of a blind 10 includes: a rotation axis 130 which rotates by means of operation of an operation chain 16 to raise and lower a screen 13; and a stopper 140 which can stop rotation of the rotation axis 130. The stopper 140 is constituted of includes a torque limiter mechanism TL1 that switches over between a rotation stop state to stop the rotation of the rotation axis 130 and a rotation stop release state the stoppage of the rotation of the rotation axis 130 when a load exceeding a predetermined amount is applied to the rotation axis 130 from the operation chain 16 in the rotation stop state. With this, the stopper 140 can be prevented from getting damaged even when an excessive torque is applied to the rotation axis 130.SELECTED DRAWING: Figure 1
【課題】回転軸に過度な回転力が加わってもストッパーが破損することを防止できるとともに、通常操作以外でもストッパーの解除が可能なブラインドの駆動装置を提供する。【解決手段】ブラインド１０の駆動装置１００は、操作チェーン１６の操作により回転しスクリーン１３を昇降させる回転軸１３０と、回転軸１３０の回転を停止可能なストッパー１４０と、を備え、ストッパー１４０は、回転軸１３０の回転を停止させる回転停止状態と、回転停止状態で、回転軸１３０に操作チェーン１６からの所定量以上の負荷が掛かったときに、回転軸１３０の回転の停止を解除する回転停止解除状態と、を切り替えるトルクリミッター機構ＴＬ１を備えて構成される。よって、回転軸１３０に過度な回転力が加わってもストッパー１４０が破損することを防止できる。【選択図】図１
