Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is a facility used for holding baseball and other sports and various large-scale events.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open / close roof stadium having a roof structure that is openable / closable and has a structure in which the roof is closed in rainy weather and the roof is opened in fine weather, and in particular, an open / closed roof stadium with an improved rain closing mechanism.

[0002]

It has been a long-standing dream to make a stadium for baseball and other outdoor sports a facility that can be held even on rainy days. As the first generation, the second generation has an air film structure such as the Metrodome in Minneapolis, USA and the Tokyo Dome completed in 1988.

Currently, the mainstream stadiums are the third-generation open / closed roof stadiums. The Pittsburgh Auditorium completed in 1961 and the Montreal Olympic Stadium completed in 1987.
There is the Melbourne National Tennis Center completed in 987, but since the opening of the Toronto Skydome in 1989 as a baseball stadium, there is a strong demand for an open / closed roof stadium.

The Tokyo Dome, which has a fixed roof with a membrane structure, has gained extraordinary popularity since its opening, but outdoor sports such as baseball and American football are naturally comfortable on sunny days under the blue sky or starry sky. It is self-evident that it is more preferable to watch the game while hitting the wind, and it is more preferable to watch it, and it seems necessary to shift from the fixed roof system to the open / closed roof system.

In response to this trend, general contractors have proposed stadiums with an open / closed roof. For details, see NIKKEI ARCHITECTURE 1988.6.27.
No. 1989.3.6., Column No.111 1989.1,
It is described in the Construction Industry Newspaper 1989.8.11. The applicant of the present application has previously filed Japanese Patent Application Nos. 2-21702-4 and 3-2.
-By 13648-9, a pair of weight-type upper dome and lower dome cut in a hyperbolic shape are combined to allow both to move in the circumferential direction, and both sides of the dome roof are released in a hyperbolic shape. In addition, a dome-shaped open / close roof stadium is proposed in which both can be moved in parallel and the entire sky above the stadium can be opened.

[0006]

In the openable roof, not limited to the dome shape as described above, a gap is formed between the roof and the roof which are separately configured and move independently in response to the request for the opening / closing operation of the roof. However, on the other hand, when the roof is closed, a mechanism for preventing rain and wind from being blown from the gap between the roof and the roof is required.

Further, since the roof is deformed by an external force such as wind, snow or an earthquake, it is necessary to set the size of the space between the roofs so as to flexibly follow the deformation. As a result, it is required that the rain protection mechanism has a structure capable of flexibly absorbing the displacement of the size of the gap between the roofs.

As is apparent from the above, the present invention aims at clarifying a retractable roof stadium having a rain protection mechanism capable of satisfying the above-mentioned requirements.

[0009]

In the open / close roof stadium according to the present invention, the roof is divided into an upper dome and a lower dome, which partially overlap each other when the roof is completely closed, and between the upper dome and the lower dome which vertically overlap each other. A rubber tube inflated in one dome and expanded by air and a cushioning member made of a flat rubber plate in the other dome are disposed in the void portion of the upper dome and the lower dome. A rain warding mechanism is provided in which the amount of displacement of the space between and is absorbed by the amount of displacement of both the rubber tube and the cushioning member.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the open / close roof stadium of the present invention will be described in detail with reference to the accompanying drawings. The structure of the opening and closing roof and the moving mechanism described below are merely examples, and the roof structure is divided into a plurality of parts, and when the roof is closed, opening and closing of the structure in which a part of the divided roof overlaps The present invention is applied to a roof stadium.

FIG. 1 shows a state in which the open / close roof is closed. The open / close roof includes an upper dome indicated by reference numeral 10,
It is composed of a lower dome indicated by 20.

The upper dome 10 has a dome-shaped cross section,
The lower dome 20 has a hyperbolic open portion when viewed from a plane, and the lower dome 20 has a dome-shaped cross section and a hyperbolic open portion different in shape from the upper dome 10. Also,
The upper dome 10 and the lower dome 20 of the present invention can also be expressed as a divergent arch shape.

The upper dome 10 and the lower dome 20 are constructed so that they can be independently driven in the circumferential direction (circular movement) in the clockwise or counterclockwise direction. Therefore, as shown in FIG. 1, from the closed state in which the upper dome 10 and the lower dome 20 overlap each other in a cross shape, as shown in FIG. However, Fig. 2 shows the fully open state from the overlapped open state to the left direction in the drawing by linear driving, so the release part can be set freely, so it can be released depending on the direction of sunlight or wind. There is an advantage that the width of the part and the releasing direction can be freely adjusted. With the combination of the bowl-shaped upper and lower domes, even if the upper and lower domes are configured so as to be freely rotatable with respect to each other, the release portion can be formed only in one direction of the dome roof.

FIG. 2 shows the upper dome 10 and the lower dome 20.
After driving in the circumferential direction and superimposing them on each other,
The figure shows a state in which the field 30 and the seats 31 are fully opened by driving them linearly.

Depending on the amount of linear movement, the roof opening ratio can be freely set from 100% on the field to 100% including the seats.

Next, a circumferential drive mechanism and a linear drive mechanism for driving and operating the upper dome 10 and the lower dome 20 in the above-described manner will be described.

As shown in FIG. 3, an annular rail 40 for driving the upper dome 10 and the lower dome 20 in the circumferential direction is provided on the outer edge of the seat 31 for the upper dome 10 and the lower dome 20. It is provided separately. Each of the annular rails 40 for the upper dome 10 and the lower dome 20 is composed of a fixed annular rail 42 and a movable annular rail 41 . The fixed annular rail 42 is attached to the upper part of the lower skeleton body 50 of the stadium, but is continuous with the movable annular rail 4
1 is arranged on the upper surface of a parallel movement base 60 arranged on a linear rail 43 described later.

When the parallel moving base 60 is in the position shown in FIG. 3, the fixed annular rail 42 and the movable annular rail 41 on the upper surface of the parallel moving base 60 are in a continuous state, and the upper dome 10 and The lower dome 20 is configured so that it can be driven in the circumferential direction in the clockwise direction and the counterclockwise direction independently of each other.

As shown in FIG. 4, the upper dome 10 and the lower dome 20 are overlapped in parallel with each other in an "overlapping open state".
Then, when the bases for parallel movement are driven and operated after the both bases are operated so as to be positioned on the movable annular rail 41 , the upper dome 10 and the lower dome 20 become the linear rails 43.
It can be operated linearly along the roof and the roof can be "fully opened".

The rain protection mechanism is arranged along the edge of the upper dome 10 as shown in phantom in FIG. 1, and schematic sectional views are shown in FIGS. 5 to 6.

In FIG. 5 to FIG. 6, 11 and 12 are the frames of the upper dome 10, 21 and 22 are the frames of the lower dome 20, and the upper dome 10 and the lower dome 20 are constructed above them. A mounting member 24 is provided on the upper surface of the lower dome 20.
A rubber tube 23 is attached via the, and a rubber plate 13, for example, is arranged as a cushioning material between the frames 11 and 12 of the upper dome 10.

FIG. 5 shows a normal overlapping state of the upper dome 10 and the lower dome 20, and FIG. 6 shows the upper dome 1.
0 or the lower dome 20 is deformed and the thickness of the air gap is narrowed, and the displacement amount of the air gap is absorbed by the rubber tube 23 and the rubber plate 13.

When the gap between the upper dome 10 and the lower dome 20 is filled with only the rubber tube 23, the upper dome 1
0 or the lower dome 20 is deformed to reduce the thickness of the gap, the rubber tube 23 needs to be largely deformed. With such a structure, when the rubber tube 23 is crushed, a large reaction force due to air pressure is generated. The upper dome 10 and the lower dome 20 have their respective frames 11, 12, 21,
A large force is applied to 22 and, therefore, the frame 11
・ 12 ・ 21 ・ 22 must be strong enough to withstand this reaction force, which causes disadvantages such as weight increase and cost increase. However, in the present invention, the displacement amount of the space between the upper dome 10 and the lower dome 20 is absorbed by not only the rubber tube 23 but also the rubber tube 23 and the cushioning material (rubber plate 13). Even if the gap is suddenly displaced, since the cushioning material (rubber plate 13) exists, the reaction force due to the deformation of the rubber tube 23 is absorbed by the cushioning material (rubber plate 13), so that the frame structure 11 The force transmitted to 12.21.22 will be greatly attenuated.

As is apparent from the above-described action of the rubber plate 13 as the cushioning material, the cushioning material can be formed not only by the rubber plate 13 but also by various members having elasticity, as well as by the rubber. It can also be formed by a rigid body attached to the frames 11 and 12 via a spring or the like.

The present invention also includes a mode in which the rubber tube 23 is attached to the upper dome 10 and the cushioning material is attached to the lower dome 20. The present invention also includes a mode in which a cushioning material is arranged also on the lower dome 20 side.

Although not described in detail, during the opening / closing operation of the roof, air is evacuated from the rubber tube 23 and the upper dome 10 is evacuated.
It is natural to operate so as to inflate the rubber tube 23 only when the roof is closed by creating a space between the lower dome 20 and the lower dome 20. Upper dome 10 and lower dome 2
A mode in which the gap between the rubber tube and the space 0 is closed by one rubber tube 23, a plurality of rubber tubes 23 arranged continuously
Alternatively, it may be closed.

Further, when the amount of deformation of the space between the upper dome 10 and the lower dome 20 is so large that it cannot be absorbed by the deformation of the cushioning material, the air in the rubber tube 23 is automatically evacuated. The present invention also includes a mode in which various safety mechanisms are arranged.

[0028]

EFFECTS OF THE INVENTION According to the open / close roof stadium of the present invention, since the rain protection mechanism for closing the gap generated in the roof has a structure capable of absorbing the amount of displacement of the gap due to the deformation of the roof, the force transmitted to the roof frame is transmitted. Can be reduced, which is effective for reducing the weight and cost of the roof structure,
The problems mentioned above are solved.
