Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hanging object in a theater or the like suitable for arranging lighting equipment and sound equipment above and below a stage so as to be able to move up and down and move freely. Related to the device.

[Conventional technology]

FIGS. 6 and 7 show an example of a hanging apparatus used in a theater or the like of this type.

The stage 2 is arranged in the center of the dome-shaped building 1 so as to be movable up and down. Around this stage 2, a multi-stage audience seat 3 and a second-floor audience seat 4 are arranged. In FIG. 1, a lifting bridge 5 is suspended so as to be vertically movable, and a large number of suspended objects 8 are suspended from a ceiling-shaped pulley-shaped frame 6 for vertical movement.

Lighting equipment, sound equipment, and the like are attached to the lifting bridge 5 and the suspended object 8, and the lighting on the stage 2 is adjusted by selectively lifting and lowering them, and the sound effect is adjusted. is there.

As shown in FIG. 7, the lifting bridge 5 includes a pair of annular outer frames a, b, c, d, an inner pair of annular frames e, and horizontal frames f, g, h disposed between the inner and outer frames. , i, each of the frames a, b... i is movable in the vertical direction, and a lighting fixture or the like is mounted at an arbitrary position.

Suspended objects 8 such as lighting fixtures are suspended via a wire 7 on a scalloped frame 6, and these suspended objects 8 are suspended via spaces between the respective frames of the lifting bridge 5.
An arbitrary suspended object 8 selectively moves up and down.

[Problems to be solved by the invention]

In order to achieve the above object, a means of the present invention comprises a bridge suspended vertically upward and downward facing a stage, a rail provided on the bridge, and a self-propelled vehicle arranged to run along the rail. A hoist, the self-propelled hoist is a frame, a motor and a winch respectively attached to the frame, and a roller provided on the frame and rotatably supported by the rail while being rotationally driven by the motor,
A hook is attached to the winch via a wire so as to be able to move up and down, and a lighting device, a sound device, and the like are mounted on the bridge and the hook, respectively.

(Operation)

If you move the bridge up and down, the lighting fixtures attached to it move up and down in conjunction with the movement, and if you move the hoist by itself along the rails provided on the bridge, the lighting suspended by this hoist Equipment for sound, sound, etc. also moves and can be transferred to any position.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

A stage 2 is vertically movably arranged in the lower center of the inside of a dome-shaped building 1, and the seats 3 and 4 are installed around the stage 2, which is the same as the prior art.

On the ceiling of the building 1 there is a suspension frame 10 via a grid suspension point 9
An elevating bridge 12 is suspended from the suspending frame 10 via an elevating mechanism such as a winch 11 so as to be movable up and down, and frames 13 and 13 constituting the bridge 12 are respectively illuminated with lighting fixtures 14 and 15. Is attached to adjust the angle freely,
The lighting effects of the stage 2 and its vicinity are adjusted in accordance with the elevation position of the bridge 12 and the angles of the illuminators 14 and 15. It goes without saying that sounding equipment and other suspended objects may be attached in place of the lighting equipment 14 and 15.

The bridge 12 is composed of an outer annular bridge 16, an inner annular bridge 17, and four horizontal bridges 18 provided between the inner and outer bridges 16, 17, and each of the annular bridges 16, 17 and the horizontal bridge 18 are assembled by columns. .

The outer and inner annular bridges 16 and 17 are, as shown in FIGS.
And the upper and lower annular frames 22, erected on the main posts 19, 20
23, a pair of left and right annular rails similarly fixed to the inner peripheral side of the main columns 19 and 20, and hanging frames 24 and 25 connected to the upper and lower annular frames 22 and 23 and extending in the vertical direction, respectively
It is composed of

In each of the annular bridges 16 and 17, a self-propelled hoist 26 which is self-propelled along each of the annular bridges 16 and 17 is arranged so as to be able to travel.

The self-propelled hoist 26 is a frame 27 and a motor attached to the frame 27.
28 and winch 29, roller 30 also provided on frame 27,
A roller 32 is attached to a winch 29 via a wire 31 and can move up and down.
When the roller 30 is driven via the motor 28, the self-propelled hoist 26 runs freely in the bridges 16 and 17.

Therefore, a suspended object such as an acoustic instrument hooked on the hook 32 can freely move together with the self-propelled hoist 26.

The horizontal bridge 18 has substantially the same structure, and the horizontal bridge 18 is also provided with rails 21 'and 21', and the rails 21 of the annular bridges 16 and 17 and the rail 2 of the horizontal bridge 18 are provided.
A ring-shaped direction changing member 33 is rotatably provided at the connection portion with 1 ', and when the self-propelled hoist 26 moves from the annular bridges 16 and 17 to the horizontal bridge 18, a clock is provided via the direction changing member 33. The direction can be changed in the direction or the counterclockwise direction.

As shown in FIG. 2, a mounting baton and a reflecting plate 34 can be mounted on the middle and lower portions of both wires 31, 31 of the self-propelled hoist 26 provided on the inner and outer annular bridges 16, 17, respectively.

〔The invention's effect〕

 According to the present invention, the following effects can be obtained.

Since the elevating bridge is provided above and below the stage so that the elevating bridge can be moved up and down, the lighting equipment and the audio equipment provided on the bridge can be similarly moved up and down to adjust the lighting effect and the sound effect as desired.

Similarly, a self-propelled hoist is arranged on the lifting bridge via a rail and moves along the bridge, so that lighting equipment, acoustic equipment, and other suspended objects provided on the self-propelled hoist can be arranged at any position. At the same time, the height can be adjusted according to the elevation of the bridge.

The number of self-propelled hoists and suspended objects suspended from them is small.However, moving the self-propelled hoist performs the same function as suspending a large number of suspended objects, and the installation is easy. Is also simplified.

Since the self-propelled hoist runs on the bridge side rail via a roller driven by a motor, there is no need for a manual wire or pulley to run the self-propelled hoist, so the structure is simple and remote operation is possible. It is possible and workability is improved, and the wire can be moved to an arbitrary position without being entangled by another worker or an obstacle.
