Description

[Detailed Description of the Invention] This invention relates to a flat-bed movable and retractable bleacher seat that is mainly installed in a gymnasium or the like.

In recent years, in order to use the interior of gymnasiums for multiple purposes, a large number of chairs have been placed in rows and in multiple rows in front of the stage set up in a part of the facility, except when use is required over a wide area such as for physical education. It has become increasingly used as a venue for events where a large number of people are seated.

In this case, conventionally, when arranging chairs in rows and in multiple rows in the front area of the stage, a single chair was used, and this chair was placed and removed manually. Therefore, since it requires a lot of effort and time, there is a problem in that it reduces the economic efficiency of using the facility.

This invention was made in order to solve the above problems, and the flat floor movable storage seats of this invention have a movable flat floor that can move forward and backward on a fixed floor surface via floor support rollers. A supporting double floor structure is used to form a storage airspace zone with a volume that can accommodate a movable flat floor directly below the stage installed in a part of the building, and a Two guide rails are laid parallel to the moving direction of the movable flat bed, and a guide roller is provided at the front end of the flat bed foundation frame attached to the bottom of the movable flat bed so that it can roll along the guide rails, and A plurality of folding chairs arranged in multiple rows and capable of standing up and falling down are provided on a movable flat floor, and a flat bed moving motor and a chair raising motor are mounted on the movable flat bed. It is characterized by being able to be operated in conjunction with each other.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

A storage airspace zone 1a having a volume capable of storing the bleachers A all at once is formed at a position directly below a stage 1 provided in a part of the building. A blinding plate 1b, which forms the front end wall of the stage 1 together with the front panel 5 or the rear panel 6 of the bleachers A, is provided on the front of the stage 1, which is located directly above the front opening of the storage airspace zone 1a. . Storage airspace zone 1
Two guide rails 7 are installed on the floor F, which is the bottom of the seat A, for easily and surely setting the position of the seats A when storing them all at once and pulling them out.
are laid parallel to the direction of movement.

In the front area of stage 1, spectator seats A are movably arranged. The movable flat floor 2, which serves as the base of the spectator seat A, is formed into a flat floor body of one section by a flat plate body having a width, length, and a predetermined height (see Fig. 4) that can be stored within the storage airspace zone 1a. ing. A blind plate 1 of the stage 1 is attached to the front end of the movable flat bed 2.
A front panel 5 is erected together with b to serve as a front end wall of the stage 1 when the movable flat bed 2 is pulled forward. A rear panel 6 is erected at the rear end of the movable flatbed 2, which becomes a part of the front end wall of the stage 1 when the movable flatbed 2 is stored in the storage airspace zone 1a. On the movable flat floor 2 between the front panel 5 and the rear panel 6, mounting bases 3 arranged in a row system so that spectator seats can be installed side by side are arranged in a linear raised form at multiple intervals in the front and rear direction. ing. Each row is placed on the mounting base 3 so that it can be folded forward to fit within the height range of the mounting base 3, and by standing up using the base as a fulcrum, each row can have a good field of view with respect to the stage 1. Every,
A large number of folding chairs 4 are installed so that they can be tipped over. A long flat bed foundation frame 8 is attached to the lower side of the movable flat bed 2 so as to be parallel to the guide rail 7. On the bottom surface of each flat bed foundation frame 8, as shown in FIG. A floor support roller 2a is used to support the movable flat bed 2 at a fixed height and to move the movable flat bed 2 from the storage airspace zone 1a to the front area of the stage 1. It is attached so as to be able to roll freely with respect to the floor F, which is extended in the front area. A plurality of guide rollers 9 are provided at the front end of a flat bed foundation frame 8 adjacent to the guide rail 7 so as to be able to roll with respect to the guide rail 7.

The grandstand seat A is moved from inside the storage airspace zone 1a to the front area of the stage 1 by a drive device mainly consisting of a flatbed moving motor 10 stored in the inner position of the center of the rear side. It is configured so that A can be stored and pulled out. Inside the mounting base 3 of each row, folding chairs 4 for each row are uniformly folded forward using each base as a fulcrum when the seats A move into the storage airspace zone 1a, and the seats A are placed on the stage. A chair raising/lowering motor 11 is arranged so as to be operable in conjunction with the flat bed moving motor 10 for uniformly raising the chair to a state where it can be seated again when the chair is moved to the front section. The structure for standing up and overturning the chair is based on a known mechanism (for example, Utility Model Application Publication No. 58-112159, Utility Model Application Publication No. 58-121248).
(Refer to the publication) Next, the operation will be explained.

When the front position of the stage 1 is used for a purpose that requires a wide planar area, such as for physical education, the bleachers A are stored under the stage 1 as follows. First, when the chair raising/lowering motor 11 installed for each mounting base 3 arranged in a horizontal row is driven, for example, in the forward rotation direction,
Each chair 4 is uniformly tilted forward in each row to a position in front of the mounting base 3 in each row to the same height as the mounting base 3. Therefore, at this point, by driving the flat bed moving motor 10, for example, in the forward rotation direction,
By the rolling of the floor support rollers 2a of each flat bed foundation frame 8, one section of the movable flat bed 2 can be automatically stored all at once into the storage airspace zone 1a located in front of it. At this time, since each chair 4 is at the same height as the mounting base 3, it can be smoothly and easily stored from the opening position below the blinding plate 1b into the airspace zone 1a at the back thereof. As a result, the above-mentioned position, which was previously used as a viewing seat A, can be used for multiple purposes as a wide planar area with a floor F free of obstacles. In this case, since the rear panel 6 of the movable flat bed 2 forms a front end wall of the stage 1 together with the blinding plate 1b of the stage 1, the appearance of this side can be improved.

In addition, when using Stage 1 as a venue for events with a large number of people seated, except when a wide area is required for physical education, etc.,
Pull out grandstand A again to the front section of stage 1. First, when the flat floor moving motor 10 is driven in the reverse direction opposite to the above, the seats A, which had been stored in the airspace zone 1a directly below the stage 1, are moved by the rolling of each floor support roller 2a. The movable flat bed 2 corresponding to one section can be smoothly and automatically pulled out to its front area at once. Therefore, immediately after this, when the chair raising/lowering motor 11 installed for each mounting base 3 is driven in the reverse direction opposite to that described above, each chair 4 that had been folded to the front position of each mounting base 3 will be Since each row stands up uniformly, it becomes possible to sit on each chair 4 from this point on, so that it can be used as a normal viewing seat A. In this case, the front panel 5 of the movable flat bed 2 forms the front end wall of the stage 1 together with the blinding plate 1b of the stage 1, thereby enhancing the appearance of this side.

The effects of this idea are as follows.

(1) The building has a double floor structure and the movable flat floor 2 can be stored in the storage air zone 1a formed under the stage 1, allowing the building to be used for multiple purposes.

(2) Since the movable flat bed 2 is guided by the guide rails 7 and guide rollers 9 and is moved positively and smoothly, the movable flat bed 2 does not shift to one side.

(3) Since the flat bed moving motor 10 that advances and retreats the movable flat bed 2 and the chair raising/lowering motor 11 that raises and topples the chair are all placed on the movable flat bed 2, the floor surface after the movable flat bed 2 is stored is No obstacles remain on F, making it possible to provide a floor surface that can be used over the entire area.
