DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A house 1 has a frame formed by a plurality of arch-shaped frame bodies 2 arranged in parallel and a horizontal rod 3 connecting the arranged frame bodies 2 to each other, and the frame is covered with a vinyl sheet. . Further, the vinyl sheet is divided into a first sheet 4 covering a left side portion and a second sheet 5 covering a right side portion of the frame body 2 when viewed from the front side with a vertical line as a center, and a top portion of the first sheet 4 is divided. The side end is wound around the movable shaft 6 having the same length as the entire length of the house ridge, and the second end
The top end of the seat 5 is directly fixed to the house ridge.

Therefore, when the movable shaft 6 is rotated and the first seat 4 is wound around the movable shaft 6, a gap 7 is formed between the movable seat 6 and the second seat 5 to open the house ridge. It

Incidentally, the first sheet 4 and the second sheet 5 described above.
All of the hem portions are wound around the hoisting shafts 8 and 9, and the house hem portion can be opened by winding the seat end portion around the hoisting shafts 8 and 9.

The top side end of the second sheet 5 is the frame 2
It is attached to a supporting rod 10 fixed in a direction orthogonal to the direction. Specifically, the sheet side end is folded back into the supporting rod 10 having a C-shaped cross section to polymerize the wire 11 bent in a zigzag shape. The seat is fixed by being mounted in the support rod 10. The support rod 10 is previously locked to the claw portion 13 of the U-shaped metal fitting 12 fitted to the frame body 2, and the lower opening portion of the U-shaped metal fitting 12 is formed by a wedge metal 14 as described above. It is fixed to the frame 1.

A bearing holder 15 is provided adjacent to the support rod 10.
Is provided. One end of the bearing holder 15 is formed at a mounting base end portion 16 having a U-shaped cross section.
An arm rod 1 which is fixed to the side wall and is bent in the shape of a side face and extends across the support rod 10 in parallel with the frame body 2.
7 and a bifurcated support portion 18 that is open at the tip of the arm rod 17 in a direction orthogonal to the frame body 2. It should be noted that the bifurcated support portion 18 is provided with small holes 19 at the upper ends thereof, and the mounting base end portion 16 is fitted into the frame body 2 and fixed by a wedge metal 20.

The bearing holders 15 are provided at both ends of the house and are provided at appropriate intervals in the middle of the house, and the forked support portion 18 of the bearing holder 15 has a fixed shaft 21 having the same length as the entire length of the house ridge. Is rotatably fitted. When the fixed shaft 21 is fitted into the bifurcated support portion 18, the wire 22 is inserted into the small holes 19 provided at the respective tips of the bifurcated portion, and the tip of the wire 22 is bent so that the fixed shaft is fixed. 21 does not fall out.

Further, the movable shaft 6 and the fixed shaft 21 are connected by a cord 23, and the length of the cord 23 is such that the movable shaft 6 winds the first sheet 4 and the opening portion of the house ridge is opened. The length is set to be the same as the distance between the movable shaft 6 and the fixed shaft 21 when it is most opened.

When the fixed shaft 21 is rotated in a state where the string 23 is most stretched, the string 23 is rotated by the fixed shaft 2.
1, so that the movable shaft 6 is pulled toward the fixed shaft 21 and at the same time the first sheet 4 is unwound to cover the house ridge. When the movable shaft 6 is joined to the fixed shaft 21, the top-side end of the first sheet 4 is superposed on the top-side end of the second sheet 5, thereby closing the house ridge. When opening the house ridge, the movable shaft 6 is rotated so that the first sheet 4 is wound around the movable shaft 6 contrary to the above.

Since the movable shaft 6 and the fixed shaft 21 are rotated when the house ridge is opened and closed, the tool mounting pipes 24 and 25 each having a quadrangular cross section at the end of each shaft projecting from the house are inserted. However, they are fixed with screws.

Since the coated vinyl is blown by the wind in the house, the bands 26 are stretched along the frame 2 from the top of the coated sheet at appropriate intervals.

The embodiment has the above-mentioned structure, and when the movable shaft 6 and the fixed shaft 21 are joined, the side end of the first sheet 4 fixed to the movable shaft 6 is on the side of the second sheet 5. It is piled up on the edge and the house ridge is closed. In this state, a string 23 is wound around the fixed shaft 21.

When opening the house ridge, first, a tool (not shown) having a quadrangular cross section is inserted into the tool mounting pipe 24 of the movable shaft 6 to rotate the movable shaft 6. As a result, the movable shaft 6 moves away from the fixed shaft 21 while winding the first sheet 4 and winding the cord 23, and the movable shaft 6 is supported by the supporting rod 10.
The house ridge is opened only for the distance. In addition, string 2
When all 3 are rewound, the movable shaft 6 cannot rotate,
At this time, the house ridge is most opened.

When the house ridge is opened, the first
By rotating the hoisting shafts 8 and 9 at the hem of the seat 4 and the second seat 5 to wind up the hem of each seat, the inside of the house is ventilated from the hem toward the ridge to ventilate the inside of the house. It

Next, when closing the house ridge, a tool is inserted into the tool mounting pipe 25 of the fixed shaft 21 and the shaft is rotated. When the fixed shaft 21 is rotated, the string 23 is moved to the fixed shaft 2.
1, the movable shaft 6 is pulled toward the fixed shaft 21 while rewinding the first sheet 4, and when the movable shaft 6 reaches the support rod 10, the house ridge is closed. When the fixed shaft 21 continues to rotate, the movable shaft 6 gets over the support rod 10 and is joined to the fixed shaft 21, so that the first sheet 4 fixed to the movable shaft 6 is superposed on the second sheet 5, Completely close the part.

Further, if the hoisting shafts 8 and 9 are unwound to lower the seat hem, the entire house is covered with the vinyl sheet.

[0020]

According to the present invention, the vinyl sheet for covering the house is divided into the first sheet and the second sheet.
The seat is fixed to the movable shaft, the second seat is directly fixed to the house ridge, and in the seat opening / closing device in which the fixed shaft provided in the house ridge and the movable shaft are connected by a string, the fixed shaft is fixed to the house frame. Since the bearing holder is rotatably mounted on the bifurcated support portion, the house ridge can be opened and closed over the entire length of the house, so that temperature control inside the house is easy, and the bearing holder is Since it can be installed after covering the vinyl sheet, there is an effect that the sheet is not damaged.
