DEVICE FOR RAISING/LOWERING STAGE CURTAIN, CAPABLE OF ADJUSTING SHAPE OF STAGE CURTAIN

摘要

The present invention relates to a shape-control device for raising/lowering a stage curtain, and more specifically, a device for raising/lowering a stage curtain, which is capable of, when a coupling wire with one end connected to a winding drum and the other end connected to the stage curtain is about to be separated from a receiving groove of the winding drum during a process of being wound around or released from the winding drum, effectively controlling separation of the coupling wire from the winding drum by quickly stopping operation of a driving member for rotating the winding drum so that the coupling wire between the winding drum and a guide drum can be pulled. Provided is a device for raising/lowering a stage curtain, capable of raising or lowering the stage curtain by winding coupling wires connected to the stage curtain of a specific area. The device for raising/lowering the stage curtain includes a winding drum which has a receiving groove in which the coupling wire is stacked and wound around and is rotated by a driving member connected to one side; a guide drum which is installed below the winding drum to be a certain distance away from the winding drum and has one side rotatably coupled to the winding drum by a hinge, and includes a contact guide groove which the coupling wire obtaining tension by connection to the stage curtain is inserted into and is in contact with; an elastic member which is installed to apply an elastic force to the guide drum, and rotates the guide drum in the direction to the winding drum if the tension of the coupling wire applied to the guide drum is reduced; and a control unit which controls operation of the driving member if it is detected that the guide drum is rotated in the direction to the winding drum by the elastic member.;COPYRIGHT KIPO 2015
