CHANGEOVER DEVICE OF ELECTRICAL DRIVE AND MANUAL OPERATION FOR SHUTTER APPARATUS
To provide a changeover device of electrical drive and manual operation for shutter apparatus, which realizes smooth on/off shift of the clutch.SOLUTION: A clutch 49, being inserted between a winding shaft and an electric motor both of which work to open and close a shutter, is engaged to enable the shutter curtain to be electrically opened/closed, while being disengaged to enable the shutter curtain to be manually opened/closed. The clutch 49 comprises balls 52 which are arranged in a rollable manner between a driving rotary member 46 on the electric motor side and a driven rotary member 48 on the winding shaft side, and an actuating member 70 that slides one of the driving rotary member 46 and the driven rotary member 48 in the axial direction towards the other. The reciprocatingly sliding movement of one of the rotary members in the axial direction against the other rotary member shifts the position of the balls 52 arranged on the rotary member 46, 48 between the position to engage the clutch 49 and the position to disengage the clutch 49.SELECTED DRAWING: Figure 9
【課題】クラッチのオン、オフの円滑な切り替えを実現できるシャッター装置の電動と手動の切替装置を提供すること。【解決手段】シャッターを開閉させる巻取軸と電動モータとの間に介設されていて、オンとなることでシャッターカーテンを電動で開閉移動可能とし、オフとなることでシャッターカーテンを手動で開閉移動可能とさせるためのクラッチ４９は、電動モータ側の駆動回転部材４６と巻取軸側の被動回転部材４８との間に転動自在に配置されたボール５２と、駆動回転部材４６と被動回転部材４８とのうち、一方の回転部材を他方の回転部材に対して軸方向にスライド移動させるための作動部材７０とを含んで構成され、他方の回転部材に対する一方の回転部材の軸方向への往復スライド移動により、これらの回転部材４６，４８におけるボール５２の配置位置が、クラッチ４９をオンとする位置と、クラッチ４９をオフとする位置とに切り替えられる。【選択図】図９
