Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose stadium, and more particularly to a structure of a stadium suitable for watching a game having different contents such as baseball or soccer.

[0002]

2. Description of the Related Art Conventionally, in one stadium or stadium,
For example, a so-called multipurpose stadium capable of playing baseball or soccer is disclosed in JP-A-7-217239 and is well known.

In the conventional multi-purpose stadium disclosed in this publication, as shown in FIG. 8, a part of the left and right seat groups when viewed from the center point O of the ground 1 is a crescent-shaped movable seat group 2, 3. As a result, the positions of the movable seat groups 2 and 3 are changed during baseball and during a circler so that the movable seat groups 2 and 3 can be changed to a shape that is most suitable for each competition.

At this time, the movable seat groups 2 and 3 are shown in FIG.
As shown in FIG. 2, the seats are installed in a height relationship so as to overlap with the permanent seat group 4, and one end of each of the movable seat groups 2 and 3 is a permanent seat so that the ground shape is almost fan-shaped when playing baseball. Move to overlap part of the group.

When playing soccer, the other end portions of the movable seat groups 2 and 3 are moved in the opposite direction so as to overlap a part of the permanent seat group 4 so that the ground shape becomes substantially rectangular. As a result, it is possible to secure a ground shape in which at least one baseball and soccer game can be played in one stadium.

[0006] As a multipurpose stadium of this kind,
For example, the so-called “Fukuoka Dome” built in Fukuoka, Kyushu, is well known. In this stadium, as shown schematically in FIG. 10, a permanent spectator seat group 4 is installed concentrically surrounding a circular ground 1, and the inner circumference of the circle, which is the forefront side of the permanent spectator seat group 4, is installed. Two groups of arc-shaped turning and moving spectator seats 5a and 5b, which are turnable so as to be slidably in contact with each other, are installed so as to face each other.

In this stadium, when playing baseball or playing soccer, as in the case of the stadium shown in FIG. 8, two arc-shaped turning and moving spectator seat groups 5a and 5b are included in the permanent spectator seat group 4. By turning and moving in a state of being in contact with each other, it is possible to obtain a ground shape and a seating arrangement suitable for each competition as shown in FIG. 10 or FIG.

[0008]

However, the conventional multipurpose stadium has the following problems. That is, in the multi-purpose stadium having the structure shown in FIG. 8, the movable passenger seat groups 2 and 3 are provided in such a height relationship that they overlap the upper part of the permanent spectator seat group 4, so that The permanent spectator seat 4 adjacent to the end has a lower height than the movable spectator seat, and as a result, a blind spot is formed depending on the viewing direction.

In particular, when the movable passenger seat groups 2 and 3 are moved to almost facing each other so as to form a rectangular field on the ground 1 so that a player can play soccer, the movable passenger seat groups 2 and 3 are a permanent spectator. Since it is located higher than the seat 4, it is difficult to see the front side line of the field from the rear part of the movable passenger seat group.

Therefore, in the multipurpose stadium having such a structure, in order to obtain a visual field satisfying the spectator, it is necessary to make the ground itself large so that the distance between the side line and the front of the movable spectator seat is large. However, if the ground itself is made large, there is a problem that, when watching a baseball game, the distance between the forefront of the spectators' seats and the baseline becomes too wide.

This problem also applies to the multipurpose stadium having the structure shown in FIGS. 10 and 11. That is, for example, as is clear from the cross-sectional view of FIG. 12 taken along line 12-12 of FIG. 11, it is assumed that the turning moving spectator seat groups 5a and 5b are moved to positions substantially facing each other so as to form a rectangular soccer field. , In the group of permanent spectator seats on the extension line connecting the center point of the field (the same as the center point O of the ground 1) and the corner, the corner can be seen only in the front row spectator seats, and the other seats are complete. It becomes a blind spot.

The largest reason why such a blind spot problem occurs is the presence of a movable spectator seat group. In order to install a movable or turnable spectator seat group, the movable spectator seat group is provided so as to overlap the permanent spectator seat group as shown in FIG.
It was whether to provide a circular moving group of spectator seats in front of the front of the circular permanent spectator seats.

However, in the case of FIG. 8, the movable spectator seat group inevitably becomes high as already described, which causes a blind spot. In the case of FIG. 10, however, an arc shape is formed in front of the front part of the permanent spectator seat. In order to set up the swivel movement spectator seat group, the height of the front part of the permanent spectator seats must be adjusted to the rearmost height of the swivel movement spectator seat group. In the permanent spectator seat group on the extension line connecting the center point O and the corner, the corner of the soccer field approaches the forefront of the permanent spectator seat group, which makes it difficult to see from behind.

From the above, it is possible to change the shape of the ground and the arrangement of the spectator seats to an optimum shape in response to a game of different contents such as baseball and soccer, and moreover, from any spectator seat to any game. There was a desire for a multi-purpose stadium with no blind spots and not too far away.

The object of the present invention is to solve the above-mentioned conventional problems, and a spectator capable of turning to change the shape of the ground and the arrangement of the spectator seats to an optimum shape in accordance with the competition of different contents. An object of the present invention is to provide a multi-purpose stadium which has no seats and is not too far from any spectator seat for any competition.

[0016]

SUMMARY OF THE INVENTION The present invention is a multipurpose stadium, and has the following structure to solve the above-mentioned technical problem. That is, according to the present invention, in a stadium in which a large number of spectator seats are arranged in a staircase so as to surround the ground, a first fixed spectator installed at positions substantially opposite to each other with a center point O of the ground interposed therebetween. A seat group and a second fixed spectator seat group, four movable spectator seat groups storably installed on both sides of the first fixed spectator seat group and the second fixed spectator seat group, respectively. Installed between the fixed spectator seat group and the second fixed spectator seat group, the spectator seats from the foremost part to the last part in the predetermined circumferential length can be integrally moved in the circumferential direction in two turns. The first fixed spectator seat group has a circumferential length that is longer than the circumferential length of the second fixed spectator seat group. The height from the ground is made substantially equal, and Floor surface inclination angle of the audience group also characterized by being substantially the same.

<Specific Structure in the Present Invention> The multi-purpose stadium of the present invention comprises the above-mentioned essential constituent elements, but the constituent elements are also realized in the following specific cases. The specific constituent element is characterized in that all the movable spectator seat groups can be folded and stored so as to be retracted to the side of the body forming the multipurpose stadium.

According to the multi-purpose stadium of the present invention, for example, when playing baseball at the stadium, the movable spectator seat group adjacent to the second fixed spectator seat group having a small circumferential width is stored and each turning moving spectator is stored. The seat group is moved to a position where one end of the seat group contacts the second fixed spectator seat group. In this way, when the groups of turning and moving spectator seats are brought closer to the second group of fixed spectator seats, there is a gap between one end of each group of turning and moving spectator seats and the first group of fixed spectator seats. The spectator seat group is returned and installed between one end of each turn-moving spectator seat group and the first fixed spectator seat group.

On the other hand, when playing soccer in this stadium, the group of movable spectator seats installed between the other end of each group of spectator seats for swivel movement and the first group of seats for fixed spectators are stored to make a turn. The spectator seat group and the other end move to a position where the end contacts the first fixed spectator seat group having a long width in the circumferential direction.

When the groups of turning and moving spectator seats are brought closer to the first group of fixed spectator seats, the other end of each group of turning and moving spectator seats and the second group of fixed spectator seats are opened, so that they are stored. The movable spectator seat group that had been used is returned to the other end of each circling movement spectator seat group and the second
It will be installed between the fixed spectator seat group.

Since the first fixed spectator seat group has a larger width in the circumferential direction than the second fixed spectator seat group, the turning movable spectator seat groups are located substantially opposite to each other. In other words, the widthwise middle portion of each group of spectator seats for turning movement is located on a virtual axis passing through the center of the ground. As a result, the ground shape and the seating arrangement for the spectators can be changed to an optimum shape.

By configuring the spectator seats of the multi-purpose stadium as described above, it is possible to design the heights of the foremost portions of the swiveling and moving spectator seat groups and the movable spectator seat groups from the ground to be substantially equal and Since the floor inclination angles of the stadiums can be made almost the same, the entire stadium, especially the entire spectator seat group, will have an even mortar shape, and there will be no blind spots in the spectator seats. Obtainable.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a multi-purpose stadium according to the present invention.
FIG. 1 shows a multipurpose stadium 1 according to an embodiment of the present invention.
0 is shown. The multi-purpose stadium 10 according to this embodiment is basically provided with a spectator seat stand in which a large number of spectator seats are arranged in a staircase pattern so as to surround the substantially circular ground 11.

The spectator seat stand of the multi-purpose stadium 10 is such that, when X and Y are virtual center axes that pass through the center point O of the ground 11 and are orthogonal to each other, the center axis Y is a bisector and the center point The first fixed spectator seat group 12 is installed in an angle range of 2α with O as the apex, and similarly, the central axis Y is a bisector, and the angle with the central point O as the apex is 2β.
And a second fixed spectator seat group 13 installed in the angle range.

Since the angle α is larger than the angle β, the circumferential length of the first fixed spectator seat group 12 is longer than that of the second fixed spectator seat group 13. And, on both sides of each of the first and second fixed spectator seat groups 12 and 13,
A group of movable spectator seats 14 that can be stored is installed (see FIGS. 3 and 4). The circumferential lengths of these four movable spectator seat groups 14 are all designed to be the same.

The movable spectator seat group 14 is shown in FIGS.
As shown in FIG. 1, one fixed block 14a and four movable blocks 14 are provided in the direction from the rearmost part to the frontmost part.
b, 14c, 14d, and 14e, and each movable block 14b to 14e is configured to be movable on the floor surface by wheels 15.

Further, the blocks 14a to 14e are inverted L-shaped mounts 16a to 1 so that a group of seats can be stored underneath each block in a nested manner by utilizing a stair-like arrangement of spectator seats.
6e and a seat group 17 mounted on the seat 6e. The seat group 17 on the pedestal 16a in the movable blocks 14ba to 14e is formed to be tiltable so that the back part folds over the seat part so that it can enter under the pedestal of each block located on the upper stage side.

Between the first fixed spectator seat group 12 and the second fixed spectator seat group 13, two turning movable spectator seat groups 18 capable of turning and moving in the circumferential direction so as to sandwich the central axis Y.
Is provided. Each of these turning movement spectator seat groups 18
Either the movable spectator seat group 14 adjacent to each side of the first fixed spectator seat group 12 or the movable spectator seat group 14 adjacent to each side of the second fixed spectator seat group 13 is stored. It is possible to move by turning.

Therefore, the group of turning and moving spectator seats 18 is
Sides of the first fixed spectator seat group 12 and the second fixed spectator seat group 1
The length in the circumferential direction is obtained by subtracting the length in the circumferential direction of the movable spectator seat group 14 from the distance in the circumferential direction from the side portions of the third group. As is apparent from FIGS. 1 and 2, the turn-moving spectator seat group 18 is configured such that the spectator seats from the foremost part to the last part are integrally turned in the circumferential direction.

The means for turning and moving the spectator seat group 18 is a rail (not shown) on the floor below the pedestal (not shown) forming the spectator seat group 18 within a predetermined range in the turning direction. It is installed and the wheels under the frame are placed on this rail. Then, the wheels can be rotated by a suitable electric motor (not shown), or the entire pedestal can be moved in the circumferential direction by pulling the entire pedestal in the turning direction via a wire or the like.

By constructing the spectator seat stand as described above, since each swiveling and moving spectator seat group 18 can be installed at the same height as the fixed spectator seat groups 12 and 13, the fixed spectator seat group can be installed. The height from the ground 11 at the forefront can be designed to be the same for any of the groups 12, 12, the movable spectator seat group 14, and the turning and moving spectator seat group 18.

Then, this is the group of spectator seats 18 for turning and moving.
Even when the player moves to form a rectangular field for soccer on the ground 11, it is possible to prevent the problem that the corner portion of the soccer field becomes a blind spot from some spectator seats and cannot be seen.

Next, the operation of the multipurpose stadium 10 according to the above-described embodiment will be described. In the state shown in FIG. 1, for example, the turning moving spectator seat group 18 is about to be moved so that baseball can be played at this stadium. In this case, first, the movable spectator seat group 14 adjacent to the second fixed spectator seat group 13 having the short circumferential width is stored as shown in FIG. At that time, the movable spectator seat group 1
The spectator seat group of the fixed block 14a which constitutes No. 4 is used as the rear spectator seat.

When the movable spectator seat group 14 is stored and its part becomes a space, both of the swiveling and moving spectator seat groups 18 are swiveled to a position where one end of the spectator seat group 18 comes into contact with the second fixed spectator seat group 13. . In this way, each turning movement audience seat group 18
Is moved to the second fixed spectator seat group 13, the spectator seat stand has a form as shown in FIG.

Then, since there is a gap between the other end of each of the turning and moving spectator seat groups 18 and the first fixed spectator seat group 12, the stored movable spectator seat group 14 is returned to the position as shown in FIG. It is installed between the other end of each of the turning and moving spectator seat groups 18 and the first fixed spectator seat group 12. As a result, the audience seat stand
The second fixed spectator seat group 13 becomes a fan-shaped seat group as the back net side seat group, and therefore, as shown in FIG.
Can be formed into a shape suitable for being formed on the baseball ground 19, and the seating arrangement for the audience can also be formed into a shape suitable for this. .

On the other hand, when playing soccer in the multi-purpose stadium 10, the above-described operation is performed in reverse, and between the other end of the turning and moving spectator seat group 18 and the first fixed spectator seat group 12. The group of movable spectator seats 14 installed in is stored, and each turning movement spectator seat group 18 is moved to a position where the other end contacts the first fixed spectator seat group 12 having a long width in the circumferential direction.

Then, when each turn-moving spectator seat group 18 is brought closer to the first fixed spectator seat group 12, each turn-moving spectator seat group 18 is moved.
Since there is a gap between the other end of the and the second fixed spectator seat group 13,
The movable spectator seat group 14 that has been stored is returned and installed between the other end of each turning and moving spectator seat group 18 and the second fixed spectator seat group 13, and the spectator seat stand is configured as shown in FIG. To do.

Since the first fixed spectator seat group 12 has a longer width in the circumferential direction than the second fixed spectator seat group 13, the turning moving spectator seat groups 18 are substantially opposed to each other with the center point O of the ground interposed therebetween. Will be located. In other words, the widthwise intermediate portion of each of the turning and moving spectator seats groups 18 is located on the X-axis line passing through the center point O of the ground. As a result, ground 1
1 can be changed to a shape capable of forming a rectangular field 20 for soccer, and the seating arrangement for the spectators can be adapted to the shape.

Further, the fixed spectator seat groups 12, 13, the movable spectator seat group 14, and the turning and moving spectator seat group 18 constituting the multi-purpose stadium 10 are designed to have substantially the same height from the frontmost ground 11. . The reason why the heights of the front parts of all the spectator seat groups 12, 13, 14, and 18 can be made the same is that the multipurpose stadium 10 has movable spectator seat groups 14 located on both sides of the turning and moving spectator seat group 18. This is because either one of the above is stored, and the turning movement spectator seat group 18 is turned and moved using the space.

That is, in this multipurpose stadium 10, all the spectator seat groups 12, 13, 14, and 18 are located in the same plane. In other words, in other words, the conventional stadium shown in FIG. 8 and FIG. Since some spectator seat groups do not vertically overlap with each other, it is possible to design the front part of all spectator seat groups at the same height. Of course, the floor surface inclination angles can be designed to be substantially the same in all spectator seat groups.

Therefore, in this multipurpose stadium 10,
The entire stadium, especially the entire group of spectators, can be shaped like a mortar. As a result, when the ground 11 is changed to a shape that can form the rectangular field 20 for soccer, even if the corner approaches the front of the spectator seat group, the spectator seat does not have a blind spot. You can get a proper field of view for any competition.

When the group of turning and moving spectator seats 18 is arranged in the form shown in FIG. 4 so as to watch soccer, there is a space between the forefront of the group of turning and moving spectator seats 18 and the side line of the field 20. If there is a sufficient margin, a temporary auxiliary seat 21 can be installed in that portion as shown in FIG. 7.

When the group of turning and moving spectator seats 18 are arranged in the form shown in FIG. 4 so as to watch soccer, a rectangular field 20 formed on the ground 11 is planted with natural grass 23 as shown in FIG. When the large natural grass pallet 22 is installed, the field 2
Since the surface of 0 is raised by the thickness of the pallet 22, the view from the spectator seat is improved accordingly.

[0044]

As described above, according to the multi-purpose stadium of the present invention, either one of the movable spectator seat groups located on both sides of the circling and moving spectator seat group is stored, and the space is used for the circling movement. Since the spectator seat group is swung and moved, the height from the ground at the forefront of the swirling and moving spectator seat group and the movable spectator seat group can be designed to be substantially equal, and the floor inclination angle of the spectator seat can be set to be almost the same. Can be the same,
As a result, the entire stadium, especially the entire spectator seat group, has an even mortar shape, so that there is no blind spot in the spectator seats, and an appropriate view can be obtained from any spectator seat in any competition.
