In addition to this, the chair can be stored compactly.

(Prior Art) In theaters, multipurpose halls, and the like, the arrangement of audience seats is often changed in order to accommodate performances, party formats, conference formats, number of guests, and the like. As a means of changing the layout of the seating area, for example, the chairs are not fixed on the floor, but are movable, and the arrangement of the chairs is changed as appropriate.

(Problems to be solved by the invention) However, the above-mentioned conventional means not only require a large amount of labor for rearranging chairs, etc., but also require the creation of ideal or near-ideal seating in response to various requests. It is practically difficult to build a department;
Additionally, if chairs are not needed, separate storage spaces must be provided inside and outside the theater or hall to store them, which not only increases construction costs but also increases the overall design of the building. There were also problems with the layout and layout.

Therefore, the present invention is designed to more precisely and easily change the configuration of the audience seating area in response to various requests such as performances, party formats, conference formats, number of guests, etc., and to create an ideal or close to ideal audience seating area. You can also build a chair if you don't need it.
To provide an audience seating device equipped with a means for easily storing it without requiring any storage space inside or outside a theater or hall. A further object of the present invention is to provide a passenger seat device that allows the layout of the passenger seat section to be easily changed by operating a switch without requiring a large amount of human power.

(Means for solving the problem) The present invention provides a lifting platform A driven by a motor 9.
and a chair part B placed on the upper part of the elevator platform A so as to be horizontally rotatable by the drive of a motor 35, and the audience seat apparatus is constructed from the seat part B, which is placed on the foundation surface F of a building such as a theater or a hall. I try to install multiple units side by side. and a platform section 20 for disposing the chair section B on a support section 2 attached to the upper part of the lifting platform A;
It consists of a chair unit 21 with a foldable chair 24 disposed on the base part 20, and a rectangular floor part 22 that covers the upper part of the chair unit 21. Part 20
Wheels 25 that roll on the chair unit 21 are provided so that the chair unit 21 can be taken out from an entry/exit part 26 provided on the side of the floor part 22.

(Function and Effect) A plurality of these passenger seat devices (generally several tens or more) are installed in parallel on the foundation surface F of the building, but when the chairs 24 are not in use, they are folded up and the floor portion 22 is closed. It is stored at the bottom.
The upper surfaces of the floor sections 22 of each passenger seating device are adjusted to be on the same level, and the upper surfaces become the floor surfaces.

This is attached to the floor section 22 in order to use the chair 24.
When taking the chair out from the entrance/exit part 26 provided on the side of the seat, first drive the motor 9 of a certain passenger seating device to raise the elevator platform A, and then move the chair B higher than the chair B of the adjacent seating device. The height of part B is increased by approximately height h, and the level of the base part 20 is raised to the level of the adjacent floor part 22.
The chair unit 21 is pulled out from the entrance/exit part 26 onto the adjacent floor part 22 after being at the same level as the upper surface of the chair unit 21. In this case, by rolling the wheels 25 of the chair unit 21 on the base 20, the chair unit 21 can be easily pulled out. Next, drive the motor 9 again to lower the platform A,
After lowering the chair part B, which has been raised to the height h as described above, to the same height as the adjacent chair part B, the chair unit 21 that had been pulled out onto the adjacent floor part 22 is moved back to the original floor part 22. (that is, the floor section 22 where the chair unit 21 was stored), and then each chair 24 of the chair unit 21 is erected. Thereafter, by repeating the same operation for each passenger seat device, each chair 24 of each passenger seat device is taken out and stood up on the floor section 22, and then each elevator platform A is raised and lowered to adjust the height of each chair unit 21. Prepare.

When changing the direction of the chairs 24 of each chair unit 21, with the chairs 24 stored at the bottom of the floor section 22, lift platform A is raised to move the chair section B higher than the chair section B of the adjacent passenger seating equipment. After that, the motor 35 is driven to horizontally rotate the chair part B. In this way, the rectangular floor portion 22
The corner can horizontally rotate and change direction without hitting the adjacent floor part 22.

When the chairs 24 are not in use, each chair 24 is folded and stored at the bottom of the floor section 22, and by lowering the elevator platform A, the seating area is reduced to a compact height. The upper surface of the floor portion 22 becomes the floor surface as shown in FIG. This device can also be used as a product display device or a revolving stage for fashion shows. In this case, the floor section 22 also serves as a product placement section, but by driving the motor 35 to continuously rotate the chair section B horizontally, the product display effect and fashion show effect can be achieved. can be given.

In addition, since this passenger seat system uses the motors 9 and 35 to drive the elevator platform A and the chair section B to construct the desired passenger seat system, it can be done by operating a switch without requiring a large amount of human power as in conventional means. It becomes possible to easily construct a desired seating area. Further, by programming the drive of the motors 9 and 35 in advance to construct a desired seating area, control by a computer is also possible.
