DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-purpose stadium, and more particularly to a multi-purpose stadium in which a part of a seat is movable.

[0002]

2. Description of the Related Art In recent years, multipurpose stadiums capable of holding various sports have been constructed.

[0003] By the way, if the stadium has a single purpose, it is possible to design it exclusively for that purpose.
In the case of a baseball field, a typical design in which the shape of the entire stadium is fan-shaped is sufficient.

However, in the case of multipurpose, at least
It is necessary to balance a baseball field with a game having a rectangular ground, for example, a soccer ground. If you do so, you can create a baseball stadium that requires a relatively large area, and draw a rectangular ground inside it. However, between a baseball game and a game requiring a rectangular ground, the arrangement density of spectators and the superiority of seats at various places are fundamentally different, and thus such a simple configuration cannot be put to practical use.

[0005] That is, in baseball, the infield seat centering on the back of the net is the upper seat, and a high-quality chair that does not actually get tired even for a long time watching is used. On the other hand, the seats that surround the second base, the so-called outfield seats, are connected to the next seats, and the entrance fee is set at a low price, so the design has been given priority to accommodation capacity. I have.

On the other hand, in a game requiring a rectangular ground, a baseball ground is used as a rectangular ground which is long in the direction connecting the home base and the second base. In general, in this kind of game, for example, soccer or rugby, the ground is used. The seat near the side in the longitudinal direction is the uppermost seat, and the seat located short is not only far from the player but also difficult to grasp the game situation, so it is a lower seat.

[0007] As is apparent from the above two forms, the baseball and the latter competition clearly differ in the superiority even in the seats at the same position. Yes, but in the other competition there is a lower contradiction. And the most important difference is the arrangement of the seats.

That is, in the case of a baseball stadium, it is ideal that the seats be arranged in an eccentric circular shape, whereas in the latter case, it is ideal that they are arranged in a rectangular band shape. This leaves no room for the greatest common divisor arrangement.
This indicates that the arrangement must be such that any of the sports will be hindered or that any of the sports will have some hindrance.

As a solution to this problem, for example, there is one shown in FIGS. This is provided with fixed seats 21 arranged in a circle so as to surround the ground 20. A movable seat 22 formed in a crescent shape is provided inside the fixed seat 21. The movable seat 22 can move in the direction of arrow F along the inside of the fixed seat 21.

When used as a baseball field, as shown in FIG. 9, the movable seat 22 is moved toward the back net to form a fan-shaped ground, while when used as a soccer or rugby ground, as shown in FIG. , The movable seats 22 are opposed to each other. Thereby, the movable seat 22 becomes the best spectator seat in any competition, and the shape of the ground can be made suitable for each competition.

[0011]

However, in the above-mentioned conventional apparatus, there is a problem that the fixed seat 21 located behind the back net in baseball is a lower seat in the case of soccer or rugby. . For this reason, the grade of the fixed seat 21 located behind the back net must be incomplete, and it is difficult to balance the cost of the chair and the satisfaction of the audience.

The present invention has been made in view of the above circumstances, and can take two forms, a baseball ground and a rectangular ground such as soccer, and an optimal and efficient seat arrangement in each form. It is a technical object to provide a multipurpose stadium that can be performed.

[0013]

In order to solve the above-mentioned technical problems, the present invention has the following configuration in a stadium in which seats are arranged around a ground 1.

That is, the X-axis and the Y-axis are set from the center portion 5 of the ground 1, the first fixed seat group 2 is set on the + side of the Y-axis, and the second fixed seat group 2 is set on the-side of the Y-axis. A group 3 is installed, and two movable seat groups 4, 4 are installed on the X axis so as to overlap above the first and second seat groups 2, 3, and the movable seat groups 4, 4 It is configured to move on the first and second seat groups 2 and 3 on a plurality of rails 6 installed around a central portion 5 of the ground 1.

Here, the rail 6 is connected to the movable seat group 4.
Can be arranged at positions corresponding to the front end and the rear end.
Note that the radius of curvature of the front edge of the movable seat group 4 is determined by the first radius.
And the radius of curvature of the inner peripheral edge of the second seat group 2, 3 can be set larger. Further, the movable seat group 4 can be a higher-grade seat as compared with the first and second fixed seat groups 2 and 3.

[0016]

When a game is played on a fan-shaped ground, such as a baseball ground, the two movable seat groups 4, 4 are moved onto the first fixed seat group 2 to join them.

On the other hand, when used as a soccer or rugby ground, the two movable seat groups 4, 4 are moved to opposing positions. As described above, the optimal seat arrangement can be performed in each mode, and the movable seat group 4 is always the best spectator seat, so that a high investment effect can be obtained even when the chair grade is the best. it can.

When the radius of curvature of the front edge of the movable seat group 4 is set to be larger than the radius of curvature of the inner peripheral edges of the first and second seat groups 2 and 3, the front radius of the movable seat group 4 is reduced. The edge becomes closer to a straight line, which helps to form a fan-shaped ground in the case of a baseball field, and has an effect of being able to watch games closer to the ground when used as a soccer field.

Further, by setting the movable seat group 4 to have a larger area per seat as compared with the second fixed seat group 3, it is possible to more clearly differentiate the seat grades and to meet wide audience needs. can do.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. This embodiment is adapted to a stadium in which seats are arranged around a ground 1. The present invention can be used for both baseball stadiums and competitions (hereinafter referred to as soccer for convenience) using a rectangular ground which is long in the direction connecting the home base and the second base in the baseball ground.

First, an X axis and a Y axis are set from the center portion 5 of the ground 1 so that the + side of the Y axis corresponds to the back side of the backnet when used as a baseball field. Then, the first fixed seat group 2 is installed in this portion. Since the first fixed seat group 2 is covered when used as a baseball field, the grade of the chair is relatively low, and the first fixed seat group 2 is designed to mainly accommodate a large number of spectators. And this first
The fixed seat group 2 is sized to cover a range of about 90 degrees of the circular stadium.

On the other hand, a second fixed seat group 3 is installed on the minus side of the Y axis, that is, on the outfield side of the baseball field. The second fixed seat group 3 has a size covering a range of about 120 degrees. The second fixed seat group 3 is a lower seat in any of a baseball field and a soccer field, and thus the first fixed
Like the fixed seat group 2, it is designed to mainly accommodate a large number of spectators.

The depth of the second fixed seat group 3 is set to be shorter than that of the first fixed seat group 2, and is designed so as to adjust the shape of the ground when used as a baseball field. . This will be described later.

On the X axis, two movable seat groups 4, 4 are provided so as to overlap above the first and second seat groups 2, 3, respectively. As shown in FIG. 1, the movable seat groups 4 and 4 have a deformed arc shape. In other words, at both ends of the arc, one of them is obtained by adding a slight length to the depth of the first fixed seat group 2, and the other is obtained by adding a slight length to the depth of the second fixed seat group 3. There is.

The movable seat groups 4 and 4 are installed so as to move on the first and second seat groups 2 and 3 on a plurality of rails 6 provided around a central portion 5 of the ground 1. . That is, as shown in FIG. 2, a rail 6a is laid at the rear end of the first fixed seat group 2. On the other hand, a roller 40 running along the rail 6a is provided at the rearmost portion of the movable seat group 4 located above the first fixed seat group 2. Similarly, a similar roller 41 is provided on the first fixed seat group 2 side at the front edge of the movable seat group 4, and runs on a rail 6b provided on the ground 1.

Further, a similar roller (not shown) is provided on the second fixed seat group 3 side at the front edge of the movable seat group 4 so as to run on a rail 6c provided on the ground 1. It has become. The movable seat group 4,
The vehicle 4 can travel in the direction indicated by the arrow F by a traveling motor (not shown).

The chairs of the first fixed seat group 2 are seating portions 2.
a and a backrest 2c,
a can be folded from a joint shaft 2b between the backrest 2a and the backrest 2c. This is to prevent the chair of the first fixed seat group 2 from coming into contact with the lower surface of the movable seat group 4, and such a measure is not necessarily required when the position of the movable seat group 4 is sufficiently high. Not necessary.

The chairs of the movable seat group 4 are the same as those of the first seat.
And the area per seat compared to the second fixed seat group 3,
And the quality is set high, so that it is set to be used as the upper seat.

The operation of the above configuration will be described. First, when used as a baseball ground, as shown in FIG. 4, the two movable seat groups 4, 4 are moved onto the first fixed seat group 2, and the two are joined. As a result, the two movable seat groups 4, 4 become infield seats, and the second fixed seat group 3 becomes outfield seats.

Here, when changing to use as a soccer field, the two movable seat groups 4, 4 are moved in the direction of the second fixed seat group 3. FIG. 5 shows a state in which the two movable seat groups 4 and 4 are moved by 5 degrees, respectively, FIG. 6 shows a state in which the movable seat groups are moved to 13 degrees, FIG. 7 shows a state in which they are moved to 21 degrees, and FIG. In this position, the two movable seat groups 4, 4 face each other.

By the way, the details of the gray level of the seats when this multipurpose stadium is used as a soccer field are shown in FIG. 8 as the movable seat groups 4, 4 as shown in A, B, C, and D of FIG. The center in one of the regions is the best in the region A, and therefore the price is also the highest. The next best seats are the two sides of the central portion of the one movable seat group 4 displayed in the area B. Therefore, the seat in the area B is the second most expensive after the seat in the area A.

By the way, the central portion of the other movable seat group 4 and both sides thereof, as shown by the area B ',
The price is almost the same as that of the area B, so that the price is almost the same as the price of the area B. The next best seats are the C areas at both ends of both movable seat groups 4,4. Therefore, the seat in the area C is slightly less expensive than the seat in the area B or B '. The last or cheapest seat is the fixed seat, which is the D area.

As described above, the optimum seat arrangement can be performed in each of the embodiments, and the movable seat group 4 can be arranged.
Is always the best spectator seat, and even if the chair is of the best grade, it is possible to obtain a high investment effect without waste.

When the radius of curvature of the front edge of the movable seat group 4 is set to be larger than the radius of curvature of the inner peripheral edges of the first and second seat groups 2 and 3, the front radius of the movable seat group 4 is reduced. Since the edge becomes closer to a straight line, it helps to form a fan-shaped ground in the case of a baseball field.

On the other hand, when used as a soccer field, there is an advantage that a game can be watched closer to the ground. Since the rail 6 becomes an obstacle after determining the use form of the stadium, it is desirable to cover it.

[0036]

According to the present invention, it is possible to take two forms, a baseball ground and a rectangular ground such as soccer, and to provide an optimal and lean seat arrangement in each form.

When the radius of curvature of the front edge of the movable seat group is set larger than the radius of curvature of the inner peripheral edges of the first and second seat groups, the front edge of the movable seat group becomes closer to a straight line. Therefore, it is helpful to form a fan-shaped ground when the baseball field is used. In addition, when used as a soccer field, there is an advantage that a game can be watched closer to the ground.
