Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an artificial lawn athletic stadium having an artificial lawn laid on its surface, and more specifically, it provides a soil portion around a baseball base or the like. It relates to an athletic stadium made of artificial lawn in which a base surrounded by soil can be easily installed in another place in order to perform another competition in a necessary competition.

[Detailed description of the device]

The stadium with artificial grass is used for various sports such as baseball, football and soccer. Therefore,
When used for such a multipurpose purpose, a part or all of the ground of the stadium is partially moved so as to have a predetermined ground shape. For example, in a stadium that can also be used as a baseball field, when playing baseball, it is necessary to pave the vicinity of the base and the part of the mound with soil such as Antuca in consideration of the sliding of players. On the other hand, in a game such as football or soccer, such a soil portion is an obstacle. Therefore, put the soil part in a container buried underground, and support this container vertically with a hydraulic cylinder etc.When using the stadium for purposes other than baseball, drive the hydraulic cylinder etc. The part paved with soil is lowered to the underground part for storage, and an artificial grass is laid in this part so that it is at the same level as the existing artificial grass,
Methods such as covering the front of the ground with artificial grass were taken. In addition, the stand is often moved according to the shape of the ground so that the relationship between the ground and the stand is harmonized.

By the way, for example, in baseball, there are juvenile baseball represented by the Little League and softball, and in these competitions, the distance between the base and the home plate / pitcher plate is shorter than that of the official baseball. That is, specifically, as shown in FIG. 3, the distance A between the home base 1 and the first base 2, the second base 3, and the third base 4 in the baseball game.
Is longer than the distance B between the home base 1 and the first base 5, the second base 6, and the third base 7 in the youth baseball game. Correspondingly to this, the pitch between the hard pitcher plate 8 and the home base 1 is also increased between the youth baseball pitcher plate 9 and the home base 1. Therefore, when performing a youth baseball in a stadium set up for such a hardball baseball, as mentioned above, the soil portions 11, 12 ,, which surround the 1st base 2, the 2nd base 3, and the 3rd base 4, respectively. It has been practiced to lower each 13 and lay an artificial lawn on it, and to install a first base 5, a second base 6, and a third base 7 on the artificial lawn.

[Problems to be solved by the device]

However, in such a method, the first, second and third bases 5, 6 and 7 are located on the artificial grass. When you slide on these bases, your foot may step on the artificial lawn, causing injury to your feet or injury due to frictional heat. Furthermore, there is a soil portion 14 around the home base 1,
Sliding resistance is completely different on each base and home base, as well as the driving feel. Further, the position of the pitcher plate 9 for youth baseball is close to the front edge of the soil portion 15, and even if the foot is on the soil portion 15 before the pitch, the foot is located on the artificial grass after the pitch. It is not preferable.

Therefore, the purpose of this invention is to move an area paved with soil to a predetermined place according to the competition to be used, and to form an artificial lawn that can be played safely without hindering the competition. It is to provide a sports field.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention holds a soil portion in a preset place, and holds the soil portion in an artificial lawn athletic field in which an artificial lawn is laid on the surface other than the soil portion. Holding means, a hole formed with the holding means together with the soil portion and having a size capable of moving the soil portion in a predetermined direction, a moving means for moving the holding means in the hole, and a surface An artificial lawn in which the artificial grass is formed, and the artificial grass portion is composed of a block body that is detachably accommodated in the empty space left in the hole, and the position of the soil portion and the position of the artificial grass portion in the hole. It is characterized by being replaceable.

[Action]

According to the above-mentioned means, in an artificial lawn stadium having a soil portion, the soil portion is moved to a necessary place according to the competition, and the seam between the artificial grass portion and the soil portion is changed to a portion that does not interfere with play. Since it can be brought, it is possible to avoid a danger in playing to the player.
