ロツクレバー36が設けられている。<Prior Art> FIG. 8 is a perspective view of a plastic greenhouse 20.
This vinyl house 20 has two ventilation sheets on both sides to adjust the temperature and humidity inside the greenhouse.
1 is stretched, and a sheet winding device 30 for winding up and pulling out the ventilation sheet 21 is provided. FIG. 9 is a sectional view of a conventional example of this winding device. A casing 32 is attached to be movable along the column 22 via a support roller 31 that presses against the inside of the column 22, and a rotating shaft 33 to which the winding shaft 23 of the ventilation sheet 21 is connected is attached to the casing 32. is adapted to rotate integrally with the ratchet 34. A handle 35 is attached to this rotating shaft 33, and by rotating the handle 35, the sheet 21 is wound up and pulled out. In order to prevent rotation of the ratchet 34 and rotating shaft 33, a lock lever 36 is provided which meshes with the ratchet 34.

能となつていた。<Problems to be solved by the invention> Therefore, in the conventional device, the lock lever 3
The operation was troublesome because the handle 35 had to be rotated after releasing 6. Moreover, when the lock lever 36 is released, if the handle 35 is not held in place by hand, the handle 35 will unexpectedly rotate at the same time as the release due to the weight of the seat, which is dangerous. Furthermore, since winding is performed using the ratchet 34, only step-by-step operations are possible, making detailed tensioning impossible.

It is fixed by means such as welding to brackets 9 provided at the front and rear of the frame 0, and is located in a direction perpendicular to the support column 14. A roller 7, which presses against one side of the support column 14, is freely rotatably fitted onto the fixed pipe 1. The drive shaft 3 and the driven shaft 4 are inserted coaxially from openings at both ends of the fixed pipe 1. Both the drive shaft 3 and the driven shaft 4 are made of cylinders, and the end of the drive shaft 3 inside the fixed pipe 1 has a large diameter, and the end of the driven shaft 4 is inserted into this end. Therefore, the fixed pipe 1 has a double pipe structure. Here, the driven shaft 4 is equipped with a plastic greenhouse sheet (hereinafter simply referred to as a sheet).

It is becoming more and more common. The coil spring 2 is provided between the drive shaft 3 and the fixed pipe 1, and is wound so that the outer diameter of the coil portion is slightly larger than the inner diameter of the fixed pipe 1. Therefore, the coil spring 2 is in pressure contact with the inner surface of the fixed pipe 1, and a frictional force is generated between the coil spring 2 and the fixed pipe 1. In this example,
This coil spring 2 is made of cotton material with a rectangular cross section, and is designed to ensure pressure contact with the inner surface of the fixed pipe 1.

になる。 With this configuration, the sheet is wound up by rotating the handle 15 and rotating the drive shaft 3 in the direction of arrow A in FIG. 6. As the drive shaft 3 rotates, the right end surface of the upper slit 3a of the drive shaft 3 comes into contact with the hook portion 2a at one end of the coil spring 2, and presses the hook portion 2a in the same direction.
Since this pressing direction is the winding direction of the coil spring 2, the diameter of the coil portion of the coil spring 2 is reduced, the frictional force with the fixed pipe 1 is eliminated, and the hook portion 2a is inserted into the upper slit 4a of the driven shaft 4. Touch the left end face and press it. Therefore, the driven shaft 4 rotates in the same direction, and the winding shaft connected to the driven shaft 4 rotates to wind up the sheet. This sheet is wound up when the casing 10 passes through the rollers 6 and 7 to the support 1.
This is done while moving along 4. This will be explained with reference to FIG. 8. Reference numerals 22 and 30 in FIG.
are the strut 14 and the casing 1 of this embodiment, respectively.
0, and the sheet 21 is wound up while the casing 10 moves upward along the column 14.

降移動しながら引き出されることになる。 The seat can then be pulled out by rotating the handle in the opposite direction. Due to this rotation, the left end surface of the lower slit 3b of the drive shaft 3 presses the hook portion 2b at the other end of the coil spring 2, so that the diameter of the coil spring 2 is reduced and the driven shaft 4 is brought into contact with the hook portion 2b. rotates in the same direction and the sheet is pulled out. The sheet is also pulled out while the casing 10 is moved along the support column 14 via the rollers 6 and 7 in the same manner as the above-described winding. To explain this with reference to FIG.
0) is pulled out while moving downward along the column 14 (reference numeral 22 in FIG. 8).

動軸の回転がロツクされる。 In operations other than such sheet winding and drawing operations, the rotation of the driven shaft 4 is locked by the frictional force of the coil spring 2. FIG. 7 is a sectional view showing such a state, and shows a case where a rotational force in the direction of arrow B is applied to the driven shaft 4 due to the weight of the seat. Due to this rotational force, the left end surface of the upper slit 4a of the driven shaft 4 comes into contact with the hook portion 2a at one end of the coil spring 2, and presses it in the same direction as the winding direction of the coil spring 2. Because of the opposite direction, the diameter of the coil portion increases, increasing the frictional force between it and the inner surface of the fixed pipe 1, and locking the rotation of the driven shaft 4. Therefore, the sheet winding shaft is held at the position where the sheet is wound. On the other hand, even when a rotational force in the opposite direction is applied to the driven shaft 4, the hook portion 2b at the other end of the coil spring 2 acts in the same manner as described above, so that the rotation of the driven shaft is locked.

節も容易となる。<Effects of the invention> According to the invention as described above, the sheet can be wound up and pulled out simply by rotating the handle, so the handle does not rotate inadvertently and is safe. Furthermore, the sheet can be wound steplessly. It is easy to operate because the handle can be taken up and pulled out, and the handle is locked by a coil spring when it is not used for winding or pulling out, so the handle does not rotate accidentally, making it safe. Since it can be removed and pulled out, fine adjustments can be made easily.
