By locking the lock shaft 22b of the operating portion 22 and the locking piece 23, the sliding of the connecting shaft 16 in the elongated hole 15a is restricted, and the connecting rod 8 and the connecting rod 12 are free from play due to the elongated hole 15a. It will be connected when it is gone.

The operation of the rotary louver configured as described above will be described below with reference to the drawings.

First, when the operator 30 is operated with the rotating louver plate 1 closed to rotate the operating rod 31 downward, the slide rod 10 moves downward and is connected to the slide rod 10 via the interlocking rod 11. The rod 7 interlocks and moves downward. As a result, the rotary louver plate 1 of the rotary louver plate group 5 rotates about the shaft 4 and gradually starts to open.

At that time, regarding the connecting rod 8 connected to the slide rod 10 via the interlocking rod 12, the connecting shaft 16 of the interlocking rod 12 is a connecting member.
Since it slides in the long hole 15a of 15, the movement from the slide rod 10 cannot be transmitted. As a result, as shown in FIG. 1, the rotary louver plate 1 of the rotary louver plate group 6 maintains the closed state. Therefore, initially, ventilation is performed through the rotary louver plate group 5.

When the slide rod 10 moves downward until the rotary louver plate 1 of the rotary louver plate group 5 is in a substantially half-opened state, the connecting shaft 16 of the interlocking rod 12 comes into contact with the elongated hole 15a, and thereby the connecting rod. 8 will move downwards in conjunction with the slide rod 10.
As a result, the rotary louver plates 1 of the rotary louver plate group 6 start to open with a delay.

After that, when the operator 30 is further operated to rotate the operating rod 31 to the lowermost position, the rotary louver plate 1 of the rotary louver plate group 5 is fully opened as shown in FIG. The turning louver plate 1 is in a state of being slightly closed. As described above, the rotating louver plate 1 of the rotating louver plate group 6 is opened later than the rotating louver plate 1 of the rotating louver plate group 5 by the length of the long hole 15a of the connecting member 15. It is something to do.

Next, the operation of the regulation plate 17 will be described with reference to FIGS. In the state where the rotary louver plate 1 of the rotary louver plate group 5 in FIG. 5 is closed, the regulating plate 17 has its abutting portion 19 at the wall portion 43.
The connecting shaft 16 of the interlocking rod 12
Is located on the upper end side of the elongated hole portion 18a of the connecting shaft moving hole 18.

When the rotary louver plate 1 of the rotary louver plate group 5 starts to open and then becomes half-open, the connecting shaft 16 comes into contact with the lower ends of the elongated holes 15a and the elongated holes 18a as shown in FIG. Until then, the regulation plate 17 maintains the state of being in contact with the wall portion 43a.

When the interlocking rod 12 is pulled further downward by the slide rod 10 and the connecting rod 8 moves downward and away from the wall 43a as the support arm 3 rotates, as shown in FIG. At the same time when the rotating louver plate 1 starts to open, the regulating plate 17 moves together with the connecting rod 8 in a direction away from the wall portion 43a. At this time, the regulation plate 17 is moved by the spring 20 into the shaft 17c.
Rotate to the left around the, and bend part 18b of connecting shaft moving hole 18
Is in a state of being fitted to the connecting shaft 16 as shown in the drawing. At this time, the connecting rod 12 moves the connecting portion to the slide rod 10 via the guide member 44 to the lower side of the elongated hole 44a as shown in the arrow of FIG.

As a result, the movement of the connecting shaft 16 within the elongated hole 15a is restricted, and the play of the interlocking rod 12 with respect to the connecting rod 8 is eliminated, and the elongated hole 15a
It is possible to prevent rattling of the rotary louver plate group 6 when the rotary louver plate 1 is opened. That is, when the rotary louver plate 1 of the rotary louver plate group 6 is opened without the regulation plate 17, the rotary louver plate 1 easily receives the force of wind or the like within the range of the long hole 15a. It will rotate, but the regulation plate as described above
Providing 17 makes it possible to regulate such unstable movement.

When the operating rod 31 is rotated upward in the state shown in FIG. 2, the upward movement of the slide rod 10 is transmitted to the connecting rods 7 and 8 via the interlocking rods 11 and 12, whereby the rotating louver plate group 5 The rotating louver plate 1 of 6 starts to close. At that time, the connecting shaft 16 is a regulating plate.
Since the movement within the slot 15a is restricted by 17,
The rotary louver plate 1 of the rotary louver plate group 6 also operates simultaneously with the rotary louver plate group 5.

The turning louver plate 1 of the turning louver plate group 6 is first closed due to the small opening angle, but at that time, the regulating plate 17 comes into contact with the wall portion 43a to be in the state shown in FIG. In this state, the connecting shaft 16 comes off the bent portion 18b of the connecting shaft moving hole 18 and returns to the long hole portion 18a,
It is possible to move inside the long hole 15a. After that, the operating rod 31
When is rotated upward, the connecting rod 7 is moved upward and the rotating louver 1 of the rotating louver plate group 5 is closed.

In the above, the rotary louver plate 1 of the rotary louver plate group 6
The case where the opening operation is performed later than the rotary louver plate 1 of the rotary louver plate group 5 has been described. However, by operating the restriction mechanism 21, the rotary louver plate 1 of the rotary louver plate groups 5 and 6 is moved. It can be opened and closed at the same time. In that case, the operating portion 22 is operated in a state where both the rotary louvers 1 are closed so that the lock shaft 22b thereof is projected toward the coupling member 15 side, and as shown in FIG. It should be locked to.

As a result, the movement of the connecting shaft 16 within the elongated hole 15a is restricted and the play due to the elongated hole 15a is eliminated, so that the slide rod 10
Is simultaneously transmitted to the connecting rods 7 and 8 through the interlocking rods 11 and 12, and the rotary louver plate 1 of the rotary louver plate group 6 and the rotary louver plate 1 of the rotary louver plate group 5 are The opening / closing operation is performed in synchronization. By removing the slide shaft 22 from the locking piece 23, the connecting shaft 16 of the interlocking rod 12 can freely move in the elongated hole 15a.

The connecting rods 7, 8, the slide rod 10, the upper frame 41, the lower frame 42, the vertical frame 43, etc. are each made of an extruded mold material such as aluminum.
11 and 12 are formed using steel.

Further, in the embodiment, the connecting member 15 having the elongated hole 15a is provided in the connecting rod 8, but the connecting rod 8 may be provided with the elongated hole. In that case, the regulating plate 17 is provided directly on the connecting rod 8.
