Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for opening and closing a ventilation opening of a vinyl house and a vinyl house using the method. More specifically, the present invention relates to a method for opening and closing a ventilation opening provided in a ceiling portion or a side portion of a vinyl house, and a vinyl house using the method.

[0002]

2. Description of the Related Art In a vinyl house, various plants are cultivated from flower trees for appreciation to edible vegetables. The vinyl greenhouse can be cultivated in any season by controlling the temperature inside the greenhouse to a temperature suitable for the plant to be cultivated. In general, the temperature is controlled by warming the fuel by the heat of combustion of the fuel in the winter and opening the ventilation opening in the summer to release the heat and adjust the temperature. The opening and closing of the opening of the vinyl house is performed by tucking up and down the vinyl sheet covering the opening.

[0003]

However, the conventional opening / closing method as described above has the following problems. (A) In recent years, vinyl houses have become larger. Therefore, according to the conventional method, the worker reciprocates in the lengthwise direction of the vinyl house many times to raise and lower it little by little, which requires a great deal of labor and time.

(B) A large number of arch-shaped horizontal frame members are built in the vinyl house at regular intervals. A string-shaped tightening body such as a so-called house band is stretched between the lateral members along the direction of the members in order to press the vinyl sheet stretched over them. However, when the vent opening is opened, the cord-like tightening body is weakened and loosened by the amount of entering into the inside of the curved portion corresponding to the ceiling portion of the lateral frame member, and the vinyl sheet cannot be pressed down. Therefore, the vinyl sheet may receive a wind and generate a loud wind noise, or may be rolled or broken.

[0005]

The object of the present invention is to solve the above problems.
An object of the present invention is to enable easy and quick opening / closing of a ventilation opening of a vinyl house. In addition, even when the ventilation opening is opened, the tension of the string-like tightening body is maintained so that the vinyl sheet can be pressed down easily, preventing a loud wind noise, curling or tearing even when receiving wind. The purpose is to be able to.

[0006]

[Means for Achieving the Object] The means of the present invention for achieving the above object are as follows. The first means is a method of opening and closing the ventilation opening of the vinyl house, in which one end is fixed near the ventilation opening and the other end is substantially in the length direction of the vinyl house. The vinyl sheet fixed to the winding rods that are parallel to each other is wound or rewound by rotating the winding rod, and the winding rod is pressed to the side of the horizontal frame member while being attached to the outer periphery of the horizontal frame member. It is a method for opening and closing the ventilation opening of a vinyl house, in which the ventilation opening is opened and closed by moving along.

[0007] The second means is a vinyl house, wherein the vinyl house is provided between a frame having lateral frame members which are built in at a required interval in the longitudinal direction and the lateral frame members. It is possible to cover the stretched sheet receiving member, the stretched sheet stretched to the frame, the ventilation opening formed in a portion where the stretched sheet is not stretched, and the ventilation opening. A cover sheet having one end fixed to the vicinity of the ventilation opening, a winding rod fixed to the other end of the cover sheet, and a rod driving means for rotating the winding rod forward and backward, A cord-like tightening body that presses the winding rod against the sheet receiving member side, and the covering rod is wound or rewound by rotating the winding rod to open and close the ventilation opening. , Vinyl house.

In the third means, the rod driving means comprises an operating rod having a handle and capable of rotating operation, and a transmitting means for interlockingly rotating the operating rod and the winding rod. It is a vinyl house according to the second means.

According to the fourth means, the rod driving means is provided on the guide member standing upright along the ventilation opening, the movable body movable along the guide member, and the movable body. A vinyl house according to the second or third means, comprising: a handle for rotating the winding rod.

[0010]

Since one end side of the covering sheet is fixed near the ventilation opening, when the winding rod is rotated by the rod driving means, the winding rod press-contacted to the horizontal frame member with the covering sheet interposed therebetween is covered. The sheet is moved along the horizontal frame member while being wound or unwound, whereby the ventilation opening can be opened and closed by the covering sheet. The cover sheet covering the ventilation opening is pressed against the horizontal frame member and the sheet receiving member by the string-shaped tightening body together with the winding rod. Further, even when the cover sheet is wound up and the ventilation opening is opened, the cord-like tightening body is pressed against the sheet receiving member and does not enter the inside of the lateral frame member, so that the tension is maintained and does not loosen. Thereby, the cover sheet can be sufficiently fixed.

When the rod driving means is provided with an operating rod having a handle and capable of rotating operation and a transmitting means for interlockingly rotating the operating rod and the winding rod, for example, the operating rod is formed to be long. By doing so, it becomes possible to open and close the ventilation opening of the ceiling on the ground.

The rod driving means is provided with a guide member provided along the ventilation opening, a movable body movable along the guide member, and a handle provided on the movable body for rotating the winding rod. In this case, since the winding rod is moved stably along the guide member, the ventilation opening can be opened and closed smoothly.
