In this embodiment, the covering sheet opening and closing device works by pulling down one side string 31, which in turn pulls up the other side string 32, bundling the covering sheet 12. With the covering sheet 12 bundled, the one side string 31 can be attached to the greenhouse 10 or a fixed object to maintain the open end. Alternatively, by removing the one side string 31 from the greenhouse 10 or the fixed object, the weight of the covering sheet 12 causes the other side string 32 to be pulled down and the one side string 31 to be pulled up, causing the covering sheet 12 to hang down and closing the end.

[0022] As shown in Figure 3(b), the guide portion 20 has a U-shaped portion 21 that follows the outer circumferential surface of the upper pipe 11, an upper guide end 22 located above the U-shaped portion 21 where one string portion 31 is positioned, and a lower guide end 23 located below the U-shaped portion 21 where the other string portion 32 is positioned. By using such a guide section 20, damage to the string material 30 and the covering sheet 12 can be reduced, and the string material 30 can be easily raised or lowered. Furthermore, as shown in Figure 3(a), it is preferable to position the upper guide end 22 of the greenhouse support pipe 13 further outward from the greenhouse 10 than the lower guide end 23. By positioning the upper guide end 22 further outward from the greenhouse 10 than the lower guide end 23, damage to the string material 30 is reduced, and the string material 30 can be easily raised or lowered. Furthermore, it is preferable to point the upper guide end 22 downwards. By pointing the upper guide end 22 downwards, damage to the string material 30 can be reduced, and rainwater can be prevented from entering the guide section 20.

[0023] Furthermore, the method for opening and closing the covering sheet according to this embodiment is a method for opening and closing the covering sheet in a horticultural greenhouse 10, which has an inclined upper pipe 11 at the top of the end face, from which the covering sheet 12 hangs down and covers the end face with the covering sheet 12.

By pulling down the one side string portion 31, the other side string portion 32 is pulled up and the covering sheet 12 is bundled. With the covering sheet 12 bundled, the one side string portion 31 is attached to the gardening house 10 or a fixed object to maintain the open state of the end face. By removing the one side string portion 31 from the gardening house 10 or a fixed object, the weight of the covering sheet 12 causes the other side string portion 32 to be pulled down and the one side string portion 31 to be pulled up, causing the covering sheet 12 to hang down and the end face to be closed.

[0024] As described above, according to this embodiment, the covering sheet 12 hanging down from the inclined upper pipe 11 can be bundled and pulled up by pulling down the string portion 31 on one side, and the open state of the end face can be maintained by attaching the string portion 31 on one side to the gardening house 10 or a fixed object. Furthermore, according to this embodiment, by removing the string portion 31 on one side from the gardening house 10 or a fixed object, the covering sheet 12 can be lowered and spread out on the end face by its own weight. In addition, according to this embodiment, since the other end 30b of the other string portion 32 is slidably attached to the string portion 31 on one side, the string material 30 can be easily retrieved when replacing the covering sheet 12, and the length of the string material 30 can be reduced to about 1 / 3 compared to the string material 30 used in, for example, a bamboo blind winding device. Thus, according to the covering sheet opening and closing device and covering sheet opening and closing method of this embodiment, it is possible to easily lift the covering sheet 12 that hangs down from the arch pipe 11, in particular, where the upper pipe 11 is not straight.
