WINDING DRUM AND CURTAIN OPENING/CLOSING DEVICE
To provide a winding drum and a curtain opening/closing device capable of smoothly winding up a wire and surely performing the opening/closing operation of a curtain and the like.SOLUTION: A winding drum includes a winding core part 12 rotating together with a main shaft 11 and a pulley part 16 around which a first wire for rotationally driving the winding core part 12 is stretched. The winding core part 12 includes a peripheral wall having a taper angle in a main shaft direction, a winding groove 17 including a plurality of recessed groove parts that are arranged in the peripheral wall so as to orbit in a vertical direction with respect to the main shaft direction and positioning the second wire that is wound up to the peripheral wall, a winding position feeding groove 18 which is provided to extend along the main shaft direction while crossing the winding groove 17 and moving the second wire wound around one recessed groove part of the winding groove 17 to the other recessed groove part located adjacent thereto so as to be wound thereon by rotating the winding core part 12, and a fixing part 15 for fixing on end part of the second wire. The pulley part 16 is arranged at the side of a tapered small diameter of the winding core part 12.SELECTED DRAWING: Figure 1
【課題】ワイヤの巻上げを滑らかに行い、また、カーテン等の開閉動作を確実に行うことを可能にする巻上げドラムおよびカーテン開閉装置を提供する。【解決手段】主軸１１とともに回転する巻芯部１２と、巻芯部１２を回転駆動する第１ワイヤが掛けられるプーリ部１６とを備え、巻芯部１２は、主軸方向にテーパー角を有する周壁と、主軸方向に対して垂直方向に周回する凹状溝部を周壁に複数並べてなり、該周壁に巻上げた第２ワイヤの位置決めを行う巻回溝１７と、巻回溝１７と交差して主軸方向に沿って延設され、該巻芯部１２を回転させることにより巻回溝１７の一の凹状溝部に巻回した第２ワイヤを隣接する他の凹状溝部に移動して巻回させる巻位置送り溝１８と、第２ワイヤの一端部を固定する固定部１５とを備え、プーリ部１６は、巻芯部１２のテーパー小径側に配置されることを特徴とする。【選択図】図１
