DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose arena intended to be used not only as a sports stadium for soccer, rugby, American football, baseball and the like, but also as a variety of event venues such as concerts and festivals. The present invention also relates to a variable seat layout system that optimally rearranges a seat layout according to the content of an event.

[0002]

2. Description of the Related Art Conventionally, the following multi-purpose arenas are known which are designed mainly for a baseball field, and can be used as a stadium for soccer, rugby, American football, etc. by partially rearranging the seat layout. ing.

[0003] In a conventional arena of this type, a seat layout is first determined so as to secure a size of a ground that satisfies the official baseball rules. The inner edge of the outfield seat is an arc along the outfield fence, from which a fixed seat is provided that rises up the stairs toward the outer periphery.

[0004] The infield seats are installed so as to protrude inward from a circle obtained by extending the inner circumference of the outfield seats, and are arranged closer to the first and third base lines. Behind the infield seats and behind the back net, fixed seats inclined on the stairs are provided.

The first and third base seats protruding inside the circle extending the inner circumference of the outfield seat are defined as movable seat blocks. That is, two crescent-shaped seat blocks having arcs substantially corresponding to the extended circle are provided, and the first and third base infield seats are constituted by the crescent-shaped seat blocks.

[0006] The two crescent shaped seat blocks can be moved along the extension circle. When used as a stadium for soccer or racby, two crescent-shaped seat blocks are rotated in the left direction and right direction in the baseball stadium, respectively, and two crescent-shaped blocks are connected to the line connecting the home base and the center. The seat blocks are symmetrically opposed to each other. Then, an almost rectangular ground surrounded by the audience appears.

[0007]

As described above, in the arena layout variable system for arenas designed mainly for baseball, the system can be used as other sports stadiums such as soccer and rugby, and events such as concerts and festivals. When used as a venue, there is a problem that an appropriate seat layout cannot be realized.

[0008] In the case of baseball, competition is promoted mainly around the home base, which is one corner of a large ground, and the seats are also designed with the maximum specific gravity near the back of the back net. On the other hand, in sports such as soccer and rugby, both ends of the rectangular ground attract the most attention, and in concerts and festivals, a main stage is often provided at the center of the rectangular ground. As described above, even if the two crescent-shaped seat blocks are moved to form a substantially rectangular ground, the seats surrounding the ground are unevenly distributed near the back net of the baseball (one end of the rectangular ground). . As a result, the seat layout is uneven and asymmetric for sports such as soccer and racby. In an event where a main stage is provided at the center of a rectangular ground, the layout of the seats surrounding the main stage becomes extremely uneven and asymmetric.

In the above-mentioned conventional system, the radius of curvature of the inner periphery of the outfield seat is determined from the dimensions of the ground as a certified baseball field, and the two crescent-shaped seat blocks are moved along an extended circle of the arc. Because it is a configuration that makes a rectangular ground appear, when playing soccer, Rakby or American football, etc.
There was a problem that the seats could be unnecessarily separated from the competition court, making it difficult to see the competition and lacking in the audience's excitement.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to depart from the design concept of a baseball-centered seat layout, and to provide a sports competition to be played on a rectangular ground such as soccer, rugby, and American football. In addition to the emergence of an optimal seat layout for the event, of course, it is possible to realize an appropriate seat layout for baseball, and also to realize an appropriate seat layout for event venues such as concerts and festivals. It is an object of the present invention to provide a variable seat layout system for a multipurpose arena.

[0011]

Therefore, according to the present invention, the gland is surrounded by a circular seat area in which the inner peripheral shape is circular and rises stepwise toward the outer circumference, and a circular arc of a trailing edge is formed on the inner circumference of the circular seat area. Providing two integral, fixed, crescent-shaped seat blocks that are substantially in contact with each other , and moving the crescent-shaped seat blocks along the inner periphery of the circular seat area so as to be able to be arranged at an arbitrary position; The inner side seat block of the arc-shaped portion in the predetermined range in the above is moved in the radial direction so that it can be stored in the lower space of the outer side seat block.

[0012]

When used as a baseball stadium, the two integral and fixed crescent shaped seat blocks are arranged symmetrically with respect to the line connecting the home base and the center. The arc-shaped portion in a predetermined range in the circular seat area corresponds to an outfield area in a baseball field. By moving the inner side seat block of this part on the arc in the radial direction and storing it in the lower space of the outer side seat block, the outer field is expanded to the outer side, and a ground that satisfies the official baseball rules Secure. Although this reduces the number of outfield seats, a considerable number of seats can be secured from the infield to the back of the back net.

When used as a stadium for soccer or rugby, the inner peripheral side seat block accommodated in the lower space of the outer peripheral side seat block is moved toward the center of the ground to form a uniform circular shape over the entire circumference. Make the audience area appear. Further, two integral and fixed crescent-shaped seat blocks are moved along the inner periphery of the circular seat area, and are arranged opposite to each other at symmetrical positions with respect to the center of the ground. As a result, a rectangular ground appears, and a thick group of seats is arranged along the long side, and a slightly thin group of seats is arranged along the short side.
In addition, since the inner circumference of the circular seat area is smaller in diameter than in the case of baseball, the front edge of the seat area is closer to the center of the ground. In particular, a fixed crescent moon integrated with the circular seating area

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment described below with reference to the drawings is an indoor arena having a dome roof, but the present invention can be similarly applied to an outdoor arena.

In each of the drawings, reference numeral 1 denotes a circular peripheral facility located at the outermost periphery of the arena, which is provided with various incidental facilities such as a passage surrounding the arena and an entrance to the arena. A circular seat area 2 is provided inside the circular peripheral facility 1. This passenger seat area 2 has a circular inner peripheral shape,
A large number of seats are arranged in a structure that rises stepwise from the inner circumference to the outer circumference. A predetermined portion on the outer peripheral side in the circular seat area 2 is a fixed facility fixed over the entire circumference, but the predetermined ranges 4, 5a, and 5b on the inner peripheral side are radial slide-type seat blocks, and a lower space of the outer seat block. It can be stored in. Except for the radial slide type seat blocks 4, 5a, 5b, the inner peripheral portion of the circular seat area 2 is also a fixed facility.

On the inner periphery of the circular seat area 2 are provided two crescent-shaped seat blocks 3 whose arcs of the trailing edge are substantially in contact with each other, and a group of seats which is gently inclined from the circular seat area 2 to the crescent-shaped seat block 3 is formed. You. Crescent-shaped seat block 3
Is movable along the inner periphery of the circular seat area 2.

FIG. 5 shows the structure of the crescent-shaped passenger seat block 3. One crescent shaped passenger seat block 3 is integrally formed by a base structure mainly composed of a truss structure.

In the state shown in FIG. 1, two crescent-shaped guest seat blocks 3 are symmetrically arranged with respect to the center of the ground, and a substantially rectangular ground is surrounded by the seats. This is the basic pattern. In order to change from this basic pattern to the baseball pattern of FIG. 2, the two crescent-shaped seat blocks 3 are moved and positioned in the shape of a square. Further, the radial slide type seat block 4 in the circular seat area 2 is moved in the radial direction and stored in the lower space of the outer seat block.
By accommodating the radial slide type seat block 4, the radius of curvature of the inner circumferential arc of the seat area of this portion is expanded, for example, by about 12 m, and the expanded arc becomes the outer edge of the baseball field as shown in FIG. 2. Then, the two crescent-shaped seat blocks 3 moved to the C-shaped position become infield seats along the first and third base lines, respectively.

FIG. 6 shows a detailed configuration of the radial slide type passenger seat block 4. As shown in FIG.

As shown in FIG. 6, the radial slide type passenger seat block 4 is divided at appropriate intervals in the circumferential direction so as to be a separate structural system, and each structural system is divided into four radially. Units 15a, 15b, 15c,
15d. Since the entire customer seat is configured in a stepped shape that becomes lower toward the inner periphery, the height of the customer seat units 15a to 15d divided into four in the radial direction differs from one another. Then, when a large number of seats 16 mounted on the shortest unit 15a are folded as shown in FIG.
a outside the unit 1 by sliding
5b can be stored in the lower space of the floor. Similarly, the units 15a and 15b fit in the space below the unit 15c, and the units 15a to 15c fit in the space below the unit 15d. Further, the units 15a-
15d fits in the lower space of the outer fixed seat block 17.

In the basic pattern of FIG. 1, a large radial slide type passenger seat block 4 is set from the lower side of the substantially rectangular ground to the corners of the short sides on the right and left sides. By doing so, it is possible to eliminate the seats corresponding to the two corners of the soccer court. Also, small radial slide-type seat blocks 5a and 5b are provided at portions corresponding to the remaining two corners of the soccer court, and these portions are radially slid in the same manner as described above and stored under the outer fixed seat block. can do. Appearing in this way is the pattern for a soccer game of FIG.

FIG. 4 shows the basic pattern of FIG. 1 in which the entire position of the radial slide type passenger seat block 4 is stored on the outer peripheral side without changing the position of the crescent shaped passenger seat block 3. This is one of the variation patterns for concerts, festivals and various exhibitions.

[0023]

As described above in detail, according to the system for changing the layout of the seats of the multipurpose arena according to the present invention, the multi-purpose arena is integrated with the inner circumference of the uniform circular seat area over the entire circumference.
Two regular and regular crescent-shaped seating blocks facing each other,
The basic pattern is a layout that surrounds an almost rectangular ground with a group of seats. This makes the distribution of seats optimal for supporting sports competitions on rectangular courts such as soccer, racby, and American football. In this basic pattern, when performing an event such as a concert or a festival in which a main stage or the like is provided in the center of the ground, the distribution of the audience seats is uniform and symmetrical in all directions. That is, unlike the conventional arena deformation pattern designed mainly for a baseball stadium, the distribution of the audience seats is not unevenly distributed near the back net of the baseball.
