Detailed Description of the Invention

[0001]

[Industrial application] The present invention relates to a cultivation facility using a flexible agricultural covering material having an opening / closing function. More specifically, the present invention relates to a cultivation facility that uses a covering material for soft agriculture, such as a house (greenhouse) used as a cultivation facility, a covering material such as a tunnel, which has an opening / closing function such as an entrance / exit, a work opening or a ventilation window.

[0002]

2. Description of the Related Art Generally, houses, tunnels and the like used as cultivation facilities have a long and narrow arch shape as shown in FIG. As many openings or ventilation windows as needed are installed, and a soft agricultural film with excellent heat retention and transparency is laminated as a covering material.

Usually, in order to install a doorway, a work opening, a ventilation window, etc. in a cultivation facility, a door using a dedicated frame material as shown in FIG. 5 must be used, and the installation is not easy. However, it took a lot of time, labor and money. Therefore, the number of entrances and exits tends to be minimized, and the mainstream is a cultivation facility installed at one location on the gable surface, which is relatively easy to install. However, if there is only one entrance, the worker must go through the same entrance to move to the next facility after working inside the facility, and if the facility is small, there is no significant inconvenience. The larger the facility, the more inconvenient it becomes. For example, in a house with a depth of more than 50 m, even if you want to move to the next house in front of you, you can not move to the next house without going out from the entrance on the wife side once, which is a waste of effort and time. Was very big.
