BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stage apparatus, and more particularly to a stage hanging mechanism for suspending and supporting various kinds of tools on the stage so as to be able to move up and down.

[0002]

2. Description of the Related Art As is well known, a sludge-shaped frame commonly referred to as a grape rack is provided above a general stage,
From there, various tools, such as curtains, screens, luminaires, writing slots, etc., are suspended and supported. Then, tools that need to be exchanged or raised / lowered for each performance are suspended via a baton, and the baton is raised / lowered to appropriately raise / lower.

[0003]

By the way, since the conventional general baton is a straight and long rod-shaped one, it is most suitable for suspending thin flat-shaped ones such as curtains, screens and signboards. However, it is difficult to balance the front and back and stably support the curtains and the specially-shaped curtains that are curved or thick in the front-back direction of the stage, and the large tools are difficult to support. It may not be possible to hang it. In addition, the baton does not move forward and backward or left and right only by moving up and down, and therefore it is not convenient to move the tools supported by the baton forward and backward and left and right. .

The present invention has been made in view of the above circumstances, and it is possible to stably suspend and support even a special shape or a large size one, and various suspending-supported tools may be provided as needed. The purpose is to provide an effective stage suspension mechanism that can be moved in the front-back and left-right directions.

SUMMARY OF THE INVENTION The present invention is a stage hanging mechanism for suspending and supporting various kinds of tools on a stage so that the stage can be lifted and lowered. A plurality of movable frames extending in the front-rear direction of the stage are movably mounted in the width direction of the stage, and a winch that suspends and supports tools can be moved in the front-back direction of the stage on each of the movable frames. It is characterized by being installed in.

[0006]

In the hanging mechanism of the present invention, various tools are hung and supported by the winch. Which winch is used is selected according to the size and shape of the tool to be hung and the hanging position. At the same time, the selected winch is moved in the width direction and the front-back direction of the stage to set the suspension point at the optimum position. Moreover, not only can the tools that are suspended and supported be moved up and down, but they can also be moved in any direction as needed. That is, the tool suspended by the winding and unwinding operation of the wire by the winch is moved up and down, and the tool suspended in the same direction is moved by moving the winch along the movable frame in the front-back direction of the stage, Furthermore, by moving the movable frame itself in the stage width direction with respect to the fixed frame, the winch and the tools suspended and supported by the winch are moved in the same direction.
