OPERATION DEVICE OF SOLAR SHADING DEVICE, LIFTING DEVICE OF ROLL-UP BLIND AND OPERATION PULLEY
PROBLEM TO BE SOLVED: To provide a lifting device of roll-up blind capable of preventing breaking-off of a lifting cord while performing lifting operation of a screen without interfering movement of occupants due to entanglement by the lifting cord.SOLUTION: The roll-up blind includes: a head box 1; a screen 3 which is hung down from the head box and supported thereby; and a weight bar 4 which is hung down from the lower end of the screen 3 and supported thereby. A lifting cord 5 which is laid around the lower part of the weight bar and one end of which is fixed to the head box and the other end is connected to a take-up device 6 in the head box. The take-up device 6 winds up and down the lifting cord to thereby wind up and down the screen on the weight bar. The head box 1 stores an operation device 9 that drives the drive shaft of a take-up device to rotate when an operation cord 11 is operated. The lifting cord is connected to a cord joint which is arranged to be broken off when a tensile force exceeding a tensile force is applied thereto while performing ordinary operation. The operation device includes a transmission torque limit device which shuts off transmission of a control force to the drive shaft prior to the breaking off of the cord joint when operating the operation cord.
【課題】昇降コードとの引っ掛かりによる居住者等の移動を妨げず、スクリーンの昇降操作時には昇降コードの分断を防止し得るロールアップブラインドの昇降装置を提供する。【解決手段】ヘッドボックス１から吊下支持したスクリーン３の下端にウェイトバー４を吊下支持し、ウェイトバーの下方を巻回した昇降コード５の一端をヘッドボックスに固定し、他端部をヘッドボックス内の巻取り装置６で昇降することにより、スクリーンをウェイトバーに巻取りあるいは巻戻して昇降可能とし、ヘッドボックスには操作コード１１の操作により巻取り装置の駆動軸を回転駆動する操作装置９を設けたロールアップブラインドにおいて、昇降コードには、通常操作時に作用する引張り力を超える引張り力で分断可能としたコードジョイントを接続し、操作装置には操作コードの操作時にコードジョイントの分断に先立って駆動軸への操作力の伝達を遮断する伝達トルク制限装置を設けた。【選択図】図２０
