[0001] Rigging system [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stage apparatus, and more particularly, to a rigging apparatus for vertically moving a bather pipe installed on a stage and installed with various stage facilities.

Generally, a rigging device used in a stage device is a mechanical device that lifts up and down various facilities used in the stage, that is, a stage facility.

The rigging device lifts up and down various stage facilities by using wire rope. The wire rope provided on the rotary shaft rotated by the driving motor lifts or loosens the wire rope to which the stage facility is connected to elevate the stage facility .

The rigging device used when constructing one stage is connected with the various stage facilities constituting the stage, and each stage facility is elevated independently or elevated as a whole through mutual connection.

Korean Patent Registration No. 10-1103134 discloses a rigging apparatus for raising and lowering a bather pipe installed on a stage and equipped with various stage facilities in a vertical direction.

The rigging device includes a driving unit mounted on a supporting frame on the stage, a rotating shaft horizontally installed on the supporting frame and rotated by the driving unit, and two pairs of bartending pipes arranged at predetermined intervals in the bartending pipe A plurality of double drum units for simultaneously winding and unwinding a pair of wire ropes provided on a rotary shaft, and a plurality of wire joints connecting the barton pipe and the wire rope.

In the above-mentioned rigging device, a pair of wire ropes are separated from each other by a wire joint at a lower portion of a double drum unit at regular intervals and connected to a barton pipe, and a pair of wire ropes are simultaneously unwound or rolled by a double drum unit. The Barton pipe is connected in a balanced manner and the Barton pipe is stably supported and lifted.

However, in the case of the above-described rigging device, the wire joint uses two guide rollers to change the direction of the wire rope. However, when two guide rollers are provided, the roller becomes eccentric and complicated, which increases manufacturing cost.

When the lighting device is installed in the Barton pipe, the wire cable must be extended downward in the lighting terminal box mounted on the support frame. In this case, the cable may come into contact with the rotating shaft which rotates, and the cable may be broken.
