Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to a hanging device for a stage.

[Background technology]

As shown in Figure 2, a stage hanging device installed near the ceiling of a stage in a theater, etc. consists of a horizontally long bar (baton) 2 consisting of several wire ropes 1, 1, 1 that can be freely wound and fed out. It is suspended so that it can be raised and lowered. Bar 2 has lighting equipment 3...
etc. can be hung. In order to supply electricity to electric appliances such as lighting fixtures suspended from a bar, a flat cable 4 as shown in FIG. 1 has conventionally been used hanging from a ceiling 12. The flat cable 4 will be bent as the bar 2 rises. Therefore, a basket 5 for storing the flat cable 4 was provided on the bar 2. The flat cable 4 is stored in the cage 5 while being bent. However, since the part that bends during storage was not fixed properly,
There was a problem that it sometimes protruded from the basket 5 and could not be stored securely. In the figure, 6 is a rope winding drum, and 7 is a pulley for guiding the rope.

[Purpose of invention]

Therefore, the object of this invention is to provide a stage hanging device in which the flat cable supplying electricity to the bar position is reliably stored on the bar when the bar is raised.

[Disclosure of invention]

In order to achieve the above purpose, the inventor completed this invention after extensive study.

This idea consists of a horizontal bar that can be raised and lowered from a rope that can be freely wound up and sent out, and is designed to hang objects. This is a stage hanging equipment equipped with a flat cable configured as shown in FIG. The gist of the device is a hanging device for a stage, which is characterized in that it selectively bends at a portion that naturally becomes easier to bend as the hanging device rises. This will be explained in detail below based on an example.

As shown in Fig. 3, the stage hanging device according to this invention is equipped with a horizontally long bar (baton) 8, and this bar 8 can be raised and lowered by wire ropes 9, 9, 9, which can be freely wound and fed out. is hung on. For example, lighting fixtures 3 are used by hanging from the bar 8. Wire rope 9, 9, 9
The winding and feeding of the film is performed all at once by a winding drum 10 located above the ceiling 12. Each wire rope 9 is hung on each of pulleys 11, 11, 11 arranged at appropriate intervals above a ceiling 12, and then extends downward to suspend a bar 8 under the ceiling. In order to supply electricity to the lighting fixtures 3 suspended from the bar 8, portions 13a are formed at equal intervals as shown in FIG. 4, and are thinner than other portions to facilitate bending. A flat cable 13 is used by hanging from the ceiling 12. As shown in Figure 3, there is a basket 14 for storing the flat cable 13 on the bar 8.
is being made. The flat cable 13 is
Portion 1 that facilitates bending when the bar 8 rises
3a... are bent reliably, so that they are folded and neatly stored in the basket 14. In FIG. 3, 3a is an electrical cord.

In the embodiment of the flat cable constituting the stage hanging device according to this invention, the portion that facilitates bending is thinner than the other portions. However, the configuration of the portion that facilitates bending of the flat cable is not limited to the above. For example, as shown in FIG. 5, pads 15b are intermittently attached along the entire length of the flat cable 15 to facilitate bending.
It does not matter if a is a thinner part where the pad 15b is not attached. Further, the portion that facilitates bending may be made of a softer material than other portions.

The rope suspending the bar was a wire rope in the example. However, a rope made of synthetic or natural fibers may also be used.

[Effect of idea]

The stage hanging device according to this invention consists of a horizontally long bar that can be raised and lowered from a rope that can be freely wound up and sent out, and is designed to suspend objects. A stage hanging device comprising a flat cable that is bent upward and stored,
The flat cable is formed with a portion that facilitates bending at each position where bending is required, so that the flat cable is selectively bent at the portions that naturally facilitate bending as the bar rises. Since it is characterized by a curved shape, when the bar is raised, the part that facilitates bending reliably bends, resulting in the effect that it is reliably stored on the bar.
