Description

Movable light bridge with reflective board

The present invention relates to an illumination bridge, and in detail, to install the acoustic reflector to be folded in the illumination bridge frame, the illumination bridge frame to be able to move up and down and left and right, depending on the position of the stage sometimes sometimes used as a reflector sometimes sometimes used as a reflector The present invention relates to a movable lighting bridge that also serves as an acoustic reflector.

The acoustic reflector is a device for preventing the sound of effects produced by the stage production, orchestra, such as orchestra, from being scattered and allowing the sound to be sufficiently delivered to the audience. These acoustic reflectors are needed for concert performances at multi-purpose hall-oriented domestic arts centers.

The acoustic reflector consists of a front panel, a ceiling panel and two side panels, and is installed in the order of the front panel, the ceiling panel and the side panel. With the front plate, ceiling plate, and two side plates stored in the space formed between the top and bottom of the stage, the front plate is first lowered and the front plate is installed so that the front of the stage is seen from the top of the stage, and then the ceiling plate is lowered. To the top of the front panel. Next, the two side panels are lowered to complete the acoustic reflector together with the front panel and the ceiling panel.

In order to install a ceiling plate, the apparatus which has the apparatus which raises / lowers a ceiling plate, and the apparatus which can tilt a ceiling plate (driving drive device), etc. is needed.

For example, as shown in Figure 1, the frame 24 is coupled to the center portion rotatably rotatable, the top plate 23, the first pulley 30 is mounted on the first end; A first rope 22 connected to the first pulley 30 and extending in the direction of the stage ceiling via the frame 24; A driving unit 21 mounted on the grid 20 of the stage ceiling and connected to an end of the first rope 22 extending in the direction of the stage ceiling to reduce or extend the length of the first rope; And a second rope 26 fixedly coupled to an upper portion of the frame 24 and connected to the stage ceiling, and having a fixed length such that the stage ceiling and the frame 24 are not spaced apart by a predetermined distance or more.

Here, the second pulley 25 for moving the second rope 26 to the grid 20 is further mounted, and the end extending in the direction of the stage ceiling of the second rope 26 is the second pulley. The stopper 28 which extends in the opposite direction to the stage ceiling via 25 and extends in the opposite direction to the stage ceiling of the second rope 26 restricts the movement of the second rope 26. It is more preferable that the stage ceiling and the ceiling plate 23 are not spaced apart by a predetermined distance or more. In addition, a balance weight 27 having a weight smaller than the sum of the weights of the frame 24 and the ceiling plate 23 is mounted at the end of the second rope 26 extending in the opposite direction to the stage ceiling.

When the stopper 28 contacts the grid 20, the second rope 26 does not extend any longer and the first rope 22 is operated by the driving unit 21. ), The second pulley 29 and the first pulley 30 continue to extend, and the top plate 23 of the acoustic reflector is tilted, so that the driving part 21 has an auxiliary first rope having an end fixed to the frame 24. (31) Pulling or unwinding the part controls both the vertical raising and lowering of the ceiling plate and the rotational movement of the ceiling plate.

However, this general structure is simply to move up and down the ceiling plate, such as a sound reflector function to perform a simple function of the sound reflector, there is a problem that can not be used in various other environments.

On the other hand, as an example of the power supply means of the stage lighting, as shown in FIG. 2, the lighting lamp 90 is installed in the lighting bridge frame 60, the lighting bridge frame 60 moves along the grid 20, the pulley frame 40 And a cable storage frame 30 for accommodating the cable to supply power to the lamp 90 above the grid 20, and the cable storage frame 3 to the control panel via a control cable 2 in a separate control room. In (1) it is made to adjust the illuminance.
