When a large event is held in the main event space 2, for example, when a large-scale event such as the J. League of soccer or an international competition of track and field is held, the solid line in FIG. As shown in the state, the movable spectator seats 5 are used as spectator seats without being erected, and the spectator seats 3, 3a, 4, 4a are all ground 2.
Used for the event in a.

On the other hand, when holding an event of a size such that a small number of seats can be used in a relatively small event such as the grand 2a of the event space 2, the undulating cylinder 8 is actuated to move the audience seats. 5 is erected so that another event hall 26 is formed at the level of the upper spectator seat 3a located on one side of the event space 2 as shown in FIGS. 3 and 4. Make it available as a hall.

The conversion procedure for making a part of the large-scale event facility multipurpose for use as another event hall 26 will be described in detail. First, as shown in FIG. Stored in, then
As shown in FIG. 2, the movable spectator seat 5 is erected by rotating the undulating cylinder 8 so as to rotate clockwise in the drawing with the hinge 6 at the lower end as a fulcrum. At this time, the standing position of the movable spectator seat 5 is restricted by the upper end of the movable spectator seat 5 coming into contact with the shield wall 9 that also serves as a stopper provided on the roof portion 1a of the building 1. At the same time, When the movable spectator seat 5 contacts the shielding wall 9, the movable spectator seat 5 functions as a shielding wall.

When the movable spectator seat 5 is raised, next,
From the state of FIG. 2, as shown in FIGS. 3 and 4, the stage sub-frame 14 is rotated by the extension operation of the operation cylinder 15 to be in a horizontal state, and the front end portion faces the lower end portion of the upper spectator seat 3a. Then, the lock cylinder 20 is operated to insert the lock pin 19 into the hole 18 of the block 17 on the upper spectator seat 3a side to support the tip portion of the stage sub-frame 14 and bring it into a stretched state.

After that, the stage main frame 13
The upper front stage plate 23 is advanced along the guide rails 22 so as to project forward from the stage sub-frame 14, and then the lifter 25 is operated to pass through the opening 21 of the main stage frame 13 into the rear stage. The plate 24 is pushed up so that the rear stage plate 24 is aligned with the front stage plate 23 to form a series of stage plates. Further, the spectator seat 28 is turned so as to face the stage plates 23 and 24 by turning the turntable 27.

As a result, a part of the large-scale event facility can be separated from the main event space 2, and this space can be used as the event hall 26, and the upper spectator seats 3a and the stage. Mobilize the audience to the small audience seat 28 on the main frame 13 for
Arbitrary events can be held on the front and rear stage plates 23 and 24. At this time, since the event hall 26 is separated from the main event space 2 by the movable spectator seats 5 as a shielding wall, it is effective when a music-related event such as a concert is held. Further, when the event hall 26 is formed, the inside of the pit 11 can be used as an event space such as an exhibition hall or can be used as a court for practicing a competition.

When the movable spectator seat 5 is to be used as a part of the lower spectator seat 4, the spectator seat 28 is rotated by the turntable 27 to be turned forward and the rear stage plate 24 is reversed, contrary to the above-mentioned procedure. Is lowered by the lifter 25, the front stage plate 23 is retracted, the lock pin 19 is pulled out from the hole 18, the stage subframe 14 is bent downward, and then the movable spectator seat 5 is rotated downward to move to the lower stage. The pedestal portion 10 of the spectator seat 4a is laid down to a position where the upper end of the movable spectator seat 5 can be received. As a result, the entire stage unit 12 on the back side of the movable spectator seat 5 is housed in the pit 11.

Next, FIG. 6 shows another embodiment of the present invention. The movable spectator seat 5 is erected in consideration of the height of the roof portion 1a of the building 1 and the length of the movable spectator seat 5. An example of application to a case where there is a gap between the upper end portion of the movable spectator seat 5 and the shielding wall 9 is shown. That is, the shielding wall 9
The auxiliary shield plate 34 that moves up and down along the line is arranged so that it can be wound up and down by the winch 33 installed on the roof portion 1a, and the auxiliary shield plate 34 is interposed between the upper end portion of the movable spectator seat 5 and the shield wall 9. The function of partitioning and sound insulation can be maintained.

In the case of the embodiment of FIG. 6, the auxiliary shield plate 34
By adopting, it is possible to increase the degree of freedom of design for forming the event hole 26.

Although the lighting equipment is not shown in the building 1 in the above embodiment, the lighting equipment necessary for holding the event is installed on the roof portion 1a and the wall portion, and the upper spectator seat 3a is Since the front end side of the stage sub-frame 14 has an arc shape corresponding to the arc shape, the front end side of the stage sub-frame 14 is shown unless the upper spectator seat 3a has an arc shape. Need not be arcuate, the front stage plate 23 need not be provided with a drive device, and may be moved by a drive device. Furthermore, the front stage plate 23 and the rear stage In the case where a gap is formed between the plates 24, it is sufficient to dispose a closing plate between them, and the movable spectator seat 5 serving as a shielding wall has a structure in which a sound deadening member is interposed between the plate members. I showed you It may be one fabricated as a single thing, it is a matter of course that various changes and modifications may be made without departing from the scope and spirit of the other present invention.
