[Industrial application field] The present invention is used in a place such as a stadium with a lawn for events such as sports and performing arts.
The present invention relates to a lawn slab device provided in a mechanism for replacing an artificial grass with a natural grass.

[0002]

2. Description of the Related Art Some places having a lawn include places such as a baseball stadium, an athletic stadium, a soccer stadium, and the like in which sports are performed. In recent years, there have been many all-weather stadiums in which these sports are used in different places. Further, such stadiums also hold events other than sports, such as entertainment. Such stadiums or stadiums are provided with artificial grass or natural grass.

[0003] However, depending on the type of sports, natural grass may be more desirable than artificial grass. On the other hand, there are some events where artificial grass is more desirable because natural grass is painful and difficult to manage. In the past, as long as the same stadium or stadium was used, it was not possible to select whether to use artificial grass or natural grass, and in order to do so, the stadium itself had to be selected.

Accordingly, the present applicant has already filed an application for a lawn replacement mechanism that can freely replace artificial grass and natural grass at the same stadium or the like depending on the type of sports.

In the lawn replacement mechanism, a storage recess 3 is formed at a predetermined depth from a lawn surface 1 in a place having a lawn such as a stadium (see FIGS. 3 to 5). This storage recess 3
An artificial grass floor slab 5 that moves up and down in the room is provided. The natural grass floor slab 7 is horizontally moved using the space above the artificial grass floor slab 5 in a lowered state. By this horizontal movement, the natural lawn floor slab 7 on which the natural lawn is placed can be moved from a predetermined place to another place. When replacing the natural lawn with the artificial lawn, the natural lawn floor slab 7 is moved to another place, and then the artificial lawn floor slab 5 is raised again.

[0006]

However, it is preferable that the artificial grass floor slab 5 be shaken when a game or the like is performed on the artificial grass in a position where the artificial grass floor slab 5 is raised, for example. Absent. Therefore, it is desirable to provide a fixing device for fixing at the raised position.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a lawn slab apparatus for fixing a slab that moves up and down at a raised position.

[0008]
