Description

[Detailed Description of the Invention] This invention relates to a multi-purpose seat that is a retractable staircase-like audience seat.

In recent years, in order to use the interior of gymnasiums for multiple purposes, it has become common for gymnasiums to install retractable and movable tiered seats on a portion of the floor near the wall. This viewing seat is formed by interconnecting a plurality of movable platforms with viewing chairs of increasing height so that it can be moved by expansion and contraction in the front and back direction.
When the spectator seats are used, they are pulled out one after another starting with the lowest movable platform at the front, and the entire structure is extended into a dais-like structure, so that a large number of spectators can sit on the chairs on each movable platform. Also, when not in use,
Contrary to the above, by moving backwards from the frontmost movable bed in order to return it to the rear movable bed, the entire structure is reduced to a vertical shelf under the topmost movable bed. Therefore, it is configured so that it can be stored in a storage recess provided on the wall side of a building.

However, in conventional bleachers, each tier had a large number of individual chairs installed in the longitudinal direction that could be folded up and down, so when not in use, all the chairs could be folded down for storage, but when in use, Each of the above chairs could not be used for purposes other than seating. Therefore, there has been a problem in that the range of multi-purpose use of this type of gymnasium is limited, thereby limiting economic gain.

This invention was made to solve the above problems, and its purpose is to make each seat of the movable bed reversible.
When not inverted, it can be used as a seating surface, and when inverted, it can be used as a walking surface, making it possible for each seat to be used not only for seating but also as an exhibition stand, expanding the scope of multipurpose use.
It is an object of the present invention to provide a multi-purpose seat with a retractable staircase-like audience seat, which can thereby increase economic gain.

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

First, to explain the configuration, as shown in Figure 1,
A movable platform 2 consisting of multiple stages that is supported by supports 1b of each stage and increases in height in turn is provided with rollers 1a for each stage.
By interconnecting the attached bases 1, it is formed to be able to move telescopically in the front and back directions, and when in use, it can be pulled out sequentially from the lowest and foremost movable platform 2, and the entire chick podium can be used as a platform. When not in use, it can be moved backwards to return to the bottom of the movable floor stand 2 on the rear stage side, and the whole can be reduced to a vertical shelf shape under the movable floor stand on the topmost stage (not shown) and placed on the wall side. In the retractable stair-shaped bleachers A that can be stored and stored,
The movable platform 2 of each stage is formed as follows.
In other words, the front half of each floor pedestal 2 has a U-shaped longitudinal section with one side (rear side) largely removed.
a is fixed in a mounted manner with the other side (front side) that will not be removed positioned on the front stage movable floor stand 2 side. Also, on the movable floor base 2 on the rear side of this pedestal 2a, there is a transverse passage that also serves as a footrest for each seated person when the inverted seat 4 is not inverted, that is, when the seat 4 is used as a normal seating surface. The base plate 2b is fixed in the longitudinal direction by a horizontal surface.

Next, as shown in FIG. 2, on each pedestal 2a of the above-described movable floor 2, an L-shaped plate 3 is fixed in a mounting manner to cover the top and front side of the pedestal 2a. There is. At the rear end of this plate material 3, there is an inverted seat 4 whose front surface serves as a seating surface made of cushions, etc., and whose back surface serves as a walking surface made of a hard plate, with a hinge 7 interposed at the front end.
They are connected so that they can be detached. On the rear upper surface of the base plate 2b, a support post 5 for supporting the end surface on the opposite side of the hinge 7 when the seat 4 is reversed is erected in parallel with the longitudinal direction. The height of this support pillar 5 is such that when the seat 4 is inverted, its back side becomes the same horizontal plane as the plate material 3, and its front side forms a slight gap S between it and the base plate 2b. The size of the reversible seat 4 is such that dirt can be prevented from adhering to the reversible seat 4.

Furthermore, as shown in FIG. 3, on the base plate 2b between the inverted seats 4 of each movable floor base 2 as described above, the plate material of the front movable floor base 2 is placed in an extended state when each movable floor base 2 is in use. 3 and the plate material 3 of the rear movable platform 2 is the length of one side, and the aisle platform 6 is formed by a step H corresponding to the intermediate height of both the plate materials 3 of the front and rear stages described above. It is removably arranged so that it is sometimes fixed at the above-mentioned position, and removed from the above-mentioned position when the bleachers A is expanded or contracted. Note that this passage platform 6 and the board materials 3 of each step serve as temporary special stairs in the direction of the doll platform. Therefore, although not shown, the permanent stairs of the spectator seats A are arranged on both sides of each movable platform 2.

Next, the action will be explained.

With the above configuration, when using the bleachers A,
Normally, as shown in Fig. 3, the inverted seats 4 installed on the movable platform 2 of each stage are placed in a non-inverted state on the board 3 at each position. The person is seated on each seat 4 with good cushioning, and can thereby view various events at the venue.

In addition, when the above-mentioned seats A are used as an exhibition stand for purposes other than viewing, the seats 4 installed on the movable platform 2 of each tier should be moved as shown in Figs. 1 and 2.
From the top of the board 3 that had been in place until then, the hinge 7
When the seat is flipped backwards with the center as the center, there is a support post 5 erected at the rear end of the base plate 2b, which corresponds to this reversed position, so one end of the seat 4 will be placed on this support post 5. Become. In this case, the above support pillar 5
is set at a height that allows the seat 4 to be held in a horizontal position when inverted. Therefore, each seat 4 that has been inverted as described above is quickly transformed into a walking surface arranged at the same height as the front plate 3. As a result, the walking surface formed by the top surface of the plate material 3, which has become a series of face plates, and the back surface of the seat 4 can be used for exhibitions, sculpture exhibitions, product exhibitions, etc.
It can be used for multiple purposes as a display stand for spot sales, fashion shows, etc.

According to the above, when the back part of the inverted seat 4 is used as an exhibition stand with the plate material 3 in the front part and the continuous surface part, the above-mentioned exhibition (for example, an exhibition of sculptures, etc.)
When using a platform or a platform, etc., the audience will be positioned on the floor in the front part away from the bleachers A and will be able to see the entire grandstand A, so the above-mentioned aisle stands 6 for each tier will be used. However, for example, when using the above display stands at a product exhibition or sale event, it is possible for each audience member to directly touch and see the products displayed on each tier. It becomes necessary. Therefore, in that case, by installing the above-mentioned aisle platform 6 between each inverted seat 4, this aisle platform 6 can be
Since it is formed with a step H corresponding to approximately half of the height difference between the planks 3 and 3 at each step, a special staircase is provided that allows the audience to easily ascend and descend the planks 3 and the above-mentioned passage platform 6 for each step. It becomes possible to use it as
As a result, the audience can smoothly and easily reach the exhibition stand at any stage and purchase products etc. with sufficient confirmation.

In addition, when the seat 4 is inverted and used as an exhibition stand as described above, the seat 4 in this inverted state is held by the support pillar 5 on the base plate 2b with a slight gap S maintained between the two. Since it is firmly fixed, it is possible to easily and reliably prevent the surface portion of the seat 4 from coming into sliding contact with the base plate 2b and getting dirty.

Furthermore, as mentioned above, when storing the seating area A after using each seat 4 as a non-inverted seating surface or as an inverted exhibition stand, the aisle platform 6 is removed from between each seat 4, and each seat 4, as shown in FIGS. 1 and 2, by uniformly inverting each movable bed 2, each stage becomes a planar structure with a board 3 and a seat 4 after being inverted. There will be no obstacles. Therefore, at this point, when each base 1 is moved backward from the frontmost side by the rolling of the roller 1a at each position using the driving force of a motor (not shown), the plate material 3 and the seat 4 at the time of inversion are
It is possible to move backwards in a reduced shape to a position directly below the pedestal 2a and plate material 3 on the next stage side, and as a result, the entire bleacher seat A can be reduced to a vertical shelf shape under the movable platform of the topmost stage (not shown). It can be stored on the wall of the building.

As explained above, this idea is based on the movable floor platform 2
A plate material 3 is fixed on the pedestal 2a of the pedestal 2a, and a seat 4 whose front surface is a seating surface and whose back surface is a walking surface is reversibly attached to the rear end of this plate 3. By erecting a support post 5 on top of the seat 4 that supports the inverted mode, each seat 4 can be used as a seating surface when not inverted, and as a walking surface when inverted, allowing each seat 4 to be used not only for seating but also as an exhibition stand. Since the range of multi-purpose use is expanded by making it possible to use the seats as a stand-alone seat, it is possible to increase the economic benefits of this type of seating.
