WINDING DRUM AND CURTAIN OPENING/CLOSING DEVICE
PROBLEM TO BE SOLVED: To provide a winding drum and a curtain opening/closing device which can appropriately perform winding up of a wire, and smoothly and reliably perform opening/closing operations of a curtain or the like.SOLUTION: A smart drum 7 comprises: a main shaft; a winding core part fixed to the main shaft and rotating together with the main shaft; and a pulley part fixed to the main shaft and rotating together with the main shaft, on which a first wire for rotating and driving the winding core part is hooked. The winding core part has a peripheral wall having a taper angle in a direction of a rotation axis. A guide groove for positioning a wound lower drawing wire 11 is provided on the peripheral wall so as to circle perpendicularly to the direction of the rotation axis. The pulley part is disposed on a tapered small diameter side of the winding core part.SELECTED DRAWING: Figure 1
【課題】ワイヤの巻上げを適確に行い、カーテン等の開閉動作を滑らかに、また、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】スマートドラム７に、主軸と、前記主軸に固定され該主軸とともに回転する巻芯部と、前記主軸に固定され該主軸とともに回転し、前記巻芯部を回転駆動する第１ワイヤが掛けられるプーリ部とを備え、前記巻芯部は、回転軸方向にテーパー角を有する周壁を有し、巻上げた下引きワイヤ１１の位置決めを行う誘導溝を、前記回転軸方向に対して垂直となって周回するように前記周壁に設けており、前記プーリ部は、前記巻芯部のテーパー状の小径側に配置されることを特徴とする。【選択図】図１
