The bracket 23 is rotated clockwise about the shaft 15 (direction of arrow in FIG. 8) by reducing the length by a predetermined length. Here, since the bracket 23 rotates around the shaft 15 as the cylinder 24 contracts in the axial direction, the first opening / closing panel 6 fixed to the bracket 23 via the shaft 15 is also unidirectional, that is, fixed. It will rotate around the axis 15 in the direction of overlapping with the panel 5. In this case, the second power cylinder 30 has the first
The second opening / closing panel 7 also rotates clockwise around the shaft 15 at the same speed as the rotation speed of the first opening / closing panel 6 because it rotates in the same speed around the shaft 15 in conjunction with the power cylinder 25. .

When the bracket 23 is rotated by 65 ° around the shaft 15, the first opening / closing panel 6 is also rotated by 65 ° around the shaft 15 and completely overlaps the fixed panel 5 as shown in FIG. In this case, since the second opening / closing panel 7 only rotates about the shaft 15 by 65 °, the second opening / closing panel 7 does not overlap the fixed panel 5 and projects outward from the other end 6b of the first opening / closing panel 6 in the spherical direction. It is in a state where it has been opened (indicated by the chain double-dashed line in the figure). Therefore, the second power cylinder 30 is operated to reduce the cylinder 27 by a predetermined length in the axial direction. Here, as the cylinder 27 contracts in the axial direction, the rotation boss 28 also rotates clockwise around the shaft 15,
The second opening / closing panel 7 fixed to the rotating boss 28 also further rotates around the shaft 15 in one direction at the same time, that is, in the direction in which it overlaps with the fixed panel 4, completely overlaps with the fixed panel 4, and the roof panel 4 opens. To be done.

Here, since the bracket 23 rotates counterclockwise around the shaft 15 as the cylinder 24 extends in the axial direction, the first opening / closing panel 6 and the second power cylinder 30 simultaneously move in the other direction, that is, the fixed panel. It rotates in the counterclockwise direction around the shaft 15 in the direction away from 5.

In this case as well, the second power cylinder 30 rotates counterclockwise around the shaft 15 in conjunction with the first power cylinder 25, so that the second opening / closing panel 7 and the first opening / closing panel 6 also. Shaft 15 at the same speed as the
Rotate counterclockwise around. Bracket 23 axis 1

In this case, since the second opening / closing panel 7 is completely overlapped with the first opening / closing panel 6,
The power cylinder 30 is operated to extend the cylinder 27 by a predetermined length in the axial direction, and the rotating boss 28 is rotated about the shaft 15 in the counterclockwise direction by 45 ° to move the second opening / closing panel 7 to the shaft 15. It is rotated counterclockwise by 45 ° to bring the EPDM rubbers 14, 14 of the one end 7a of the second opening / closing panel 7 into close contact with the EPDM rubbers 14, 14 of the first opening / closing panel 6 and the EPDM of the other end 7b. The rubbers 11 and 14 are brought into pressure contact with the upper surface 3a of the base portion 3 to close the roof panel 4.

(2) When only the second opening / closing panel 7 is opened / closed In order to open only the second opening / closing panel 7, only the second power cylinder 30 is operated by the controller (not shown) to move the cylinder 27 in the axial direction. Reduce by a predetermined length. Here, as the cylinder 27 contracts in the axial direction, the rotating boss 28 also rotates clockwise about the shaft 15 by 45 °, so that the second opening / closing panel 7 fixed to the rotating boss 28 also moves to the first position.
4 around the shaft 15 in the direction of overlapping the open / close panel 6.
It rotates 5 ° and completely overlaps the first opening / closing panel 6, and only the second opening / closing panel 7 is opened.

To close the second opening / closing panel 7, the second power cylinder 30 is operated to extend the cylinder 27 in the axial direction by a predetermined length, and the rotating boss 28 is rotated counterclockwise around the shaft 15. The second opening / closing panel 7 is rotated about the shaft 15 in the counterclockwise direction by 45 °, and the EPDM rubbers 11 and 14 at the other end 7b of the second opening / closing panel 7 are attached to the upper surface 3a of the base 3. Press against.

(3) When only the first opening / closing panel 6 is opened / closed To open only the first opening / closing panel 6, refer to FIG. 10 and FIG.
As shown in FIG. 1, the control unit (not shown) actuates the first power cylinder 25 to reduce the cylinder 24 in the axial direction by a predetermined length, thereby causing the bracket 23 to rotate clockwise around the shaft 15 (see FIG. 8). 65 ° in the direction of the middle arrow), and at the same time, the second power cylinder 30 is operated to extend the cylinder 27 in the axial direction by a predetermined length, and the rotation boss 28 is rotated counterclockwise around the shaft 15. Rotate 65 °.

Here, since the bracket 23 rotates clockwise around the shaft 15 as the cylinder 24 contracts in the axial direction, the first opening / closing panel 6 fixed to the bracket 23 via the shaft 15 also. At the same time, it rotates about the shaft 15 in the direction in which it overlaps with the fixed panel 5. On the other hand, the second power cylinder 30 is rotated around the shaft 15 at the same speed in conjunction with the first power cylinder 25, but at the same time, the cylinder 27 is extended in the axial direction by a predetermined length so that the rotation boss 28 is formed. Since it rotates counterclockwise around the shaft 15, the rotating boss 28 is held in a stopped state with respect to the fixed panel 5, and the second opening / closing panel 7 fixed to the rotating boss 28 also remains stopped. As a result, only the first opening / closing panel 6 is opened.

To close the first opening / closing panel 6, the first power cylinder 25 is operated by a controller (not shown) to extend the cylinder 24 in the axial direction by a predetermined length so that the bracket 23 is rotated by the shaft 15. Rotate counterclockwise 65 ° around the second power cylinder 3
0 is actuated to reduce the cylinder 27 by a predetermined length in the axial direction, and the rotating boss 28 is rotated clockwise about the shaft 15 by 65 °.

Since the bracket 23 rotates counterclockwise around the shaft 15 as the cylinder 24 extends in the axial direction, the first opening / closing panel 6 fixed to the bracket 23 via the shaft 15 is used. At the same time, it rotates about the shaft 15 in the direction away from the fixed panel 5. On the other hand, since the first power cylinder 25 and the second power cylinder 30 operate in conjunction with each other, the rotation boss 28 is held in a state of being stopped with respect to the fixed panel 5, so that the rotation boss 28 is fixed to the rotation boss 28. The opened second opening / closing panel 7 also remains stopped, and as a result, the first opening / closing panel 6 is closed.

Further, a shaft for supporting the first and second opening / closing panels 6 and 7 and a shaft 15 for rotatably supporting the first opening / closing panel 6 are supported coaxially and rotatably on the shaft 15. Since the second opening / closing panel 7 is configured by the turning boss 28 that rotatably supports the first opening / closing panel 7, the first and second opening / closing panels 6 and 7 can be turned on the same axis.

The ridges 12 of the first opening / closing panel 6 are pressed against the EPDM rubber 11 of the fixed panel 5, and the EPDM rubbers 14, 14 at the one end 7a of the second opening / closing panel 7 are connected to the EPDM rubber of the first opening / closing panel 6. 14 and 14 and the other end 7b
Since the EPDM rubbers 11 and 14 are pressed against the upper surface 3a of the base portion 3, the adhesion between the fixed panel 5, the first opening / closing panel 6 and the second opening / closing panel 7 can be enhanced. It is possible to improve the rain behavior and the wind behavior between the panels 5 to 7.

In the above embodiment, the second power cylinder 30 is configured to operate in conjunction with the first power cylinder 25, but the second power cylinder 30 has the first power cylinder 30.
Of course, the power cylinder 25 may be operated independently of the power cylinder 25 of FIG. In this case, a drive mechanism may be provided separately for each cylinder.
