Description

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 rectangular field can be easily changed to a diamond-shaped field.

[0002]

2. Description of the Related Art Various sports such as soccer and baseball are conducted using dedicated fields. For example, soccer and rugby use a rectangular field, and baseball uses a diamond field. for that reason,
In conventional stadiums, it is usual to set the shape of the field and the seats of the spectators according to the main competition to be held there.

[0003] This means that when various competition fields are to be stacked, the shape of the spectator seats is set according to the largest field among them, and competitions that are smaller than this are mainly used. In this case, it cannot be said that the stadium's premises are being used effectively, and in the case of a competition held in a field other than the largest field, problems such as the content of the competition becoming difficult to see from the audience seats will occur. Is.

[0004]

By the way, in a general stadium, it is rare that only the main competition is held throughout the year. For example, it is usually used in other competitions during the off season of the main competition. Is. In this way, it is desirable to change not only the shape of the field but also the shape of the spectator seats when playing a competition other than the main competition. Otherwise, depending on the position of the audience seats, the content of the competition may be difficult to see.

However, in the conventional stadium, since the spectator seats cannot be easily moved, when the shape of the field is changed, the changed field comes close to the spectator seats. There was a risk that athletes and their tools would jump into the audience seats.

In order to avoid such a problem, a part of the spectator's seat has been removed to provide an appropriate space between the changed field and the spectator's seat. There was a problem that it took time to restore it. In particular, when a rectangular field used in soccer or the like is changed to a diamond-shaped field used in baseball, the number of spectator seats to be removed increases because the shape is greatly different, and the labor required for this is enormous.

On the other hand, some stadiums change the shape of the field by providing a circular seat for the spectators and providing a crescent-shaped movable seat inside the circle.
Since the movable seat turns and moves, the problem that it is impossible to permanently install the natural grass in that part has not been solved.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above conventional problems, and it is an object of the present invention to provide a multipurpose stadium in which a rectangular field can be easily changed to a diamond field.

[0009]

The present invention is a multipurpose stadium, and is configured as follows in order to solve the above-mentioned technical problems. That is, the present invention is provided with a substantially rectangular field and a staircase-like spectator seat group provided around the field and looking down on the field, and by changing the shape of the spectator seat group, the shape of the field can be changed. A multi-purpose stadium used for the purpose of changing the rectangular field into a substantially diamond-shaped field, in order to change the rectangular field into a substantially diamond-shaped field, the diamond-shaped It is characterized in that it rolls back corresponding to the top of the field.

The staircase-like spectator seat group of the multipurpose stadium to which the present invention is directed has a storage space on the lower side, and a part of the front side of the spectator seat group corresponds to the top of the diamond-shaped field in this storage space. It can be rolled back.
Here, the front side of the spectator seat group along at least both long sides of the rectangular field is rolled back.

Depending on the size of the diamond-shaped field, it is possible to roll back not only the spectator seat groups along both long sides of the rectangular field but also the front side of the spectator seat groups along one or both of the short sides. it can.
