Description

Curtain driving stage apparatus

The present invention relates to a curtain driving stage device, and more particularly, it is possible to perform the opening and closing operation of the curtain smoothly by a relatively simple structure, and can be installed in an expandable type as necessary, the curtain driving stage advantageous in terms of usability, etc. Relates to a device.

In general, a theater or theater performance hall is provided with curtains for opening and closing the stage or screen when needed. In the case of the manual opening / closing structure, the manual operation type is relatively simple and inexpensive. If you have trouble to approach the curtain position one by one, the curtains installed with both sliding doors can not open and close the curtain at a time, and if the curtain is installed high or obstacles around it depending on the surrounding environment It is often difficult to open and close the curtains by manual operation due to poor contact with the back.

Has the disadvantages. For example, a theater stage usually has a straight path portion in front of the stage and side path portions on both sides. However, since the curtain drive device is linear in most cases, the linear path portion and both side path portions of the stage are separate. Separate curtain drive unit or electric curtain drive unit should be installed only on the straight path part of the stage, and manual curtain opening and closing device should be installed on the side path part of the stage, which is cumbersome and expensive. However, when opening or closing the curtain, there is a disadvantage of separately driving the curtain driving unit installed separately from the straight path part and the both side path parts of the stage. In particular, in the case of installing the manual curtain opening and closing device on both sides of the stage, The linear path part of the stage is opened and closed by an electric curtain driving unit. Since the curtain of the side position to open and close, there is a disadvantage such as inconvenient during use.

The present invention is to solve the above problems, the object of the present invention is designed to open and close the curtain smoothly with only a relatively simple structure, while driving the dynamic curtain while satisfying the structural simplification and cost reduction of the manual operation type The smooth and convenient operation of curtain opening / closing operation can be provided, and the main part that guides the opening and closing of curtains can be installed in a bent form according to the site conditions, so it is very easy in the field installation work, It is possible to reduce the cost and to open and close the curtains in a batch, and to provide a curtain driving stage device having a new structure which is very convenient even in use.
