DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a part of a vinyl house, and FIG. 2 is a plan view of the same. In the figure, reference numeral 1 is an arch frame body, and a plurality of adjacent horizontal frames 2 provided in the length direction of the house are connected and fixed to the arch frame bodies 1 arranged side by side. Then, a vinyl sheet is formed by covering the house frame with a vinyl sheet. Incidentally, the arch frame bodies 1 are arranged in parallel at intervals of 50 to 60 cm, and the length of the entire house is about 50 to 100 m.

On the top of the arch frame 1, a left sheet storage cylinder 3 and a right sheet storage cylinder 4 each having a C-shaped cross section are arranged so that their openings are directed toward the center of the arch frame 1. It is fixed to the frame 1. In addition, between the left and right seat housing cylinders 3 and 4, a skylight frame body 5 is fixed at its lower end to the arch frame body 1 and both sides of which are exposed above the left and right seat housing cylinders 3 and 4. It is provided. Since the skylight frame body 5 is provided in each arch frame body 1, the skylight frame body 5 is also connected to and fixed to a plurality of second transverse frames 6 provided in the length direction of the house. The frame is reinforced.

The vinyl sheet covering the frame of the house is such that, when the house is viewed from the front, the first sheet 7 extends from the left hem of the house to the left sheet storage cylinder 3 and the right seat extends from the right hem to the right sheet storage cylinder 4. And the second sheet 8. Each of the seats 7 and 8 has its hem rolled up so that outside air can be taken into the house. Further, the ceiling sheet 9 covering the skylight frame body 5 has a net portion 10 formed in the middle thereof, and each end portion thereof has left and right sheet storage cylinders 3, 4
It is designed to get inside.

The net portion 10 of the ceiling sheet 9
Is in the center of the skylight frame 5, the outside air is taken into the house through the net for ventilation, and one end is wound into the left and right seat storage cylinders 3 and 4, and When the skylight frame body 5 is completely covered, the inside of the house and the outside air are shut off and ventilation is stopped.

It should be noted that the above description is a general description of the embodiment, and next, each part will be described in detail.

First, the left sheet storage cylinder 3 and the right sheet storage cylinder 4 will be described. Since they have the same structure,
Only one will be described. Since the sheet storage cylinder 3 needs to have the same length as the entire length of the house, if the end portion of the sheet 7 is inserted into the sheet storage cylinder 3 in a wound state,
Since the sheet bends in the cylinder due to the weight of the sheet, neither winding nor rewinding is possible. Therefore, the support ring 30 is fixed to the arch frame 1 at appropriate intervals, and the guide roller 31 for holding the sheet wound inside the support ring 30 is attached via the spring rod 32.

About three guide rollers 31 may be provided on the support ring 30 at equal intervals, and the spring rod 32 also serves as the rotation shaft of the roller, so that the roller portion faces the center of the sheet storage cylinder 3. I am trying to be urged.

Further, the sheet storage cylinder 3 is previously cut in accordance with the mounting interval of the support ring 30, and the storage cylinder member 3 is cut in advance.
a is formed, and the end portion of the accommodating cylinder member 3a is fixed to the inside of the support ring 30 with a screw to fix them. As a result, each of the housing cylinder members 3a is formed with a length extending to the entire length of the house through the support ring 30.

Since the end portion of the ceiling sheet 9 is wound around the seat shaft 11 and is inserted into the accommodating cylinder 3 while being wound around the seat shaft 11, the winding portion of the ceiling sheet 9 is the support ring. It is supported by the guide rollers 31 of 30, and the winding and rewinding of the sheet shaft 11 is smoothly performed.

Although not shown, the seat shaft 1 is
If 1 is made to project from the accommodating cylinder 3, a chain sprocket is provided at the projecting portion, and the chain is hung on the chain sprocket, the skylight part can be easily opened and closed on the ground.

Further, the seat shaft 11 needs a stationary means for holding the position when the seat shaft 11 is wound and unwound. Further, the ceiling sheet 9 is strongly stretched by being locked with the second horizontal frame 6 provided on the projecting portion of the skylight frame body 5 and the third horizontal frame 12 provided on each of the sheet storage cylinders 3 and 4. Rainwater does not enter the house through the skylight frame 5.

A channel type support rod 13 extending in the length direction of the house is fixed to the side portions of the left sheet storage cylinder 3 and the right sheet storage cylinder 4 and the first support rod 13 is fixed to the support rod 13.
The ends of the sheet 7 and the second sheet 8 are fixed. The sheet and the support rod 13 are connected to each other by inserting the end portion of the sheet into the support rod and mounting a wire bent in a zigzag shape in the support rod 13 to fix the sheet.

Besides, since the skylight frame 5 and the end portions of the left and right sheet accommodating cylinders 3 and 4 (the front part of the house) are open, the skylight frame body is provided so that rainwater does not enter the house from the parts. Although not shown, sheets are attached to both ends of the sheet storage cylinder 5 and the sheet storage cylinders 3 and 4.

In the embodiment shown in FIG. 1, the net portion 10 of the ceiling sheet 9 is located at the center of the skylight frame 5 in the state shown in FIG. 1, so that the inside of the house communicates with the outside air through the net portion 10. ing. Therefore, if the hem portions of the first and second seats 7 and 8 are rolled up, the outside air is taken in from the hem portion inside the house, and the hot air accumulated on the ceiling portion is discharged from the net portion 10, whereby the inside of the house is released. The outside air is freely ventilated.

When the ventilation work is completed and the roof of the house is closed, the seat shaft 11 of either the left or right seat storage cylinder 3 or 4 is rotated (or one seat shaft is rotated in the direction in which the seat is wound). Along with the rotation, the other sheet shaft is rotated in the unwinding direction). Now, when the ceiling sheet 9 is wound into the left sheet housing cylinder 3, the ceiling sheet 9 is wound around the seat shaft 11 and the net portion 10 is also housed in the sheet housing cylinder 3, so that all the skylight frame bodies 5 are ceiling sheets. It is covered with 9 and the house ceiling is shielded from the outside air.

At the same time, the first and second sheets 7 and 8
Ventilation inside the house will not be performed if the hem of is lowered. In short, the ceiling sheet 9 is moved along the skylight frame body 5 depending on whether the sheet shaft 11 is rotated in the direction in which the sheet is wound or in which one is rotated in the winding direction and the other is rotated in the unwinding direction. This will ventilate the house.

In the embodiment, the sheet storage cylinders 3 and 4 are provided on the upper surface of the arch frame body 1, but the sheet storage cylinders may be provided inside the arch frame body 1, that is, the house.
