[Solution Means for Solving the Problems] In order to solve the above problems, the present invention allows only a specific rotating louver plate to be actuated with a delay behind other rotating louver plate groups. There are two types of use modes, one is a state in which only the rotary louver plate group is closed and the other rotary louver plate group is in an open state for ventilation, and the other is a mode in which all the rotary louver plates are in the open state for ventilation. The purpose of this invention is to prevent the specific rotational louver plate group opened with a delay from rattling due to the delay play portion.

Therefore, in the present invention, in a movable louver that opens and closes by interlocking a large number of rotating louver plates provided in a frame body, the rotating louver plate is appropriately divided into a plurality of rotating louver plate groups, and each rotating louver plate is divided. In the plate group, the rotating louver plates are connected by connecting rods, respectively, and the connecting rods of the rotating louver plate groups are linked by the interlocking rods and can be moved up and down by interlocking with the operating rod. A connecting rod of the rotary louver plate group is configured by connecting two members, a louver fixed side member and a link side member, and the specific rotary louver plate group is provided at a connecting portion between the louver fixed side member and the link side member. Is provided with a delay play portion for delaying and operating the specific rotating louver plate group between the louver fixing side member and the linking side member of the specific rotating louver plate group.

Further, the vertical movement of the linking side member 8b is transmitted to the linking side member 7b of the connecting rod 7 via the interlocking rod 10.

The louver fixing side member 8a and the linking side member 8b of the connecting rod 8 are
A delay play portion is provided for delaying each rotary louver plate 1 of the rotary louver plate group 6. The delay play portion is formed by elongated holes 11, 11 provided at both upper and lower ends of the linking side member 8b. That is, the delay play part of the connecting rod 8 is
As shown in the figure, the other end of the connecting piece 9, 9 whose one end is fixed to the louver fixing side member 8a is slidably fitted into the elongated holes 11 and 11 so that the louver fixing side member 8a and the linking side member 8b.
And are formed so as to have play by sliding on each other by the length of the long holes 11, 11.

Further, a spring 12 is provided between the louver fixing side member 8a and the linking side member 8b to constantly bias the louver fixing side member 8a upward with respect to the linking side member 8b. One end of the spring 12 is attached to the interlocking rod 10 of the linking side member 8b and the connecting shaft 13, and the other end is attached to the locking member 14 provided on the louver fixing side member 8a. Further, the connecting shaft 13 extends to the louver fixing side member 8a and fits into the long hole 15 provided in the louver fixing side member 8a.

By providing the delay play part, the movement of the linking side member 8b is transmitted to the louver fixing side member 8a with a delay of the elongated hole 11. When the rotary louver plates 1 of the rotary louver plate groups 5, 6 are closed, the linking side member 8b slides above the louver fixed side member 8a by the length of the elongated hole 11 as shown in FIG. The lower ends of the elongated holes 11, 11 of the linking side member 8b are in contact with the connecting pieces 9, 9 of the louver fixing side member 8a.

Further, the connecting rod 8 is provided with a restriction mechanism 21 for restricting and releasing the play between the louver fixing side member 8a and the linking side member 8b due to the elongated hole 11. The regulation mechanism 21 includes an operation unit 22.

The lock receiving hole 23 is provided at a position facing the operation portion 22 of the linking side member 8b as shown in the figure. Further, the lock receiving hole 23 is located opposite to the lock shaft 22b of the operating portion 22 in a state where all the rotary louver plates 1 are closed (state of FIG. 1), and the lock shaft 22b of the operating portion 22 is 4th when projected
As shown in the figure, the tip end of the lock shaft 22b is fitted into the lock receiving hole 23. When the lock shaft 22b of the operation portion 22 is fitted into the lock receiving hole 23, the louver fixing side member 8a and the linking side member 8b of the connecting rod 8 are connected in a state where there is no play due to the elongated hole 11.

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 to rotate the operating rod 31 downward with the rotating louver plate 1 of FIG. 1 closed, the linkage of the connecting rod 8 connected to the operating rod 31 via the link arm 32 is performed. The side member 8b is interlocked and moves downward. The movement of the linking side member 8b is transmitted through the interlocking rod 10, and the connecting rod 7 synchronously 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 this time, with respect to the louver fixing side member 8a connected to the rotary louver plate 1 of the connecting rod 8, the movement from the linking side member 8b is not transmitted due to the play of the elongated hole 11 of the connecting piece 9.
As a result, as shown in FIG. 2, the rotary louver plate 1 of the rotary louver plate group 6 maintains the closed state. Therefore, at first, the ventilation is performed only through the rotary louver plate group 5.

When the rotary louver plate 1 of the rotary louver plate group 5 is in a substantially half-opened state (the state shown in FIG. 2), the upper end of the elongated hole 11 of the linking side member 8b contacts the connecting piece 9. Thereafter, when the operator 30 further moves the linking side member 8b of the connecting rod 8 downward, the louver fixing side member 8a moves downward together with the linking side member 8b. As a result, the rotary louver 1 of the rotary louver plate group 6 starts to open with a delay. Operating rod of operator 30
When 31 is rotated to the lowermost position, the rotary louver plate group 5 is fully opened and the rotary louver plate group 6 is slightly closed, as shown in FIG.

When the rotary louver plate 1 of the rotary louver plate group 6 is in the open state, the louver fixing side member 8a is moved upward by the spring 12 (direction in which the delayed state of the rotary louver plate 1 is maintained).
The rotary louver plate 1 does not rattle even when subjected to a force such as wind because it is urged to the upper end of the elongated hole 11 of the linking side member 8b with a constant force. That is, when the rotating louver plate 1 of the rotating louver plate group 6 is opened without the spring 12, the rotating louver plate 1 does not have a force for holding the opened state, and therefore a force such as wind is not applied. When received, rattling occurs within the range of the long hole 11, but such instability can be eliminated by providing the spring 12 as described above.

When the operating rod 31 is rotated upward in the state shown in FIG. 3, the connecting rod 8
The upward movement of the linking side member 8b is transmitted to the connecting rod 7 and the louver fixing side member 8a, and the rotary louver plate groups 5 and 5 start to close at the same time. In that case, since the opening angle is small, the rotary louver plate group 6 is closed first.

In the above, the rotary louver plate 1 of the rotary louver plate group 6
Although the case where the opening operation is performed later than the rotating louver plate 1 of the rotating louver plate group 5 has been described, the rotating louver plate groups 5 and 6 can be simultaneously opened and closed by operating the restriction mechanism 21. . In that case, the operating portion 22 is operated with both the rotating louvers 1 shown in FIG.
Is projected to the side of the linking side member 8b and fitted into the lock receiving hole 23 as shown in FIG.

As a result, the movement of the connecting piece 9 in the elongated hole 11 is restricted and there is no play, so that the linking side member 8b and the louver fixing side member 8a move simultaneously, and the rotary louver plate 1 of the rotary louver plate group 6 is moved. Opens and closes in synchronization with the rotary louver plate 1 of the rotary louver plate group 5.

In addition, connecting rods 7, 8, slide rods 10, interlocking rods 11, 12, upper frame 4
1, the lower frame 42, the vertical frame 43, etc. are each formed by using an extruded mold material such as aluminum.

In the above embodiment, the rotary louver plate 1 is divided into two rotary louver plate groups 5 and 6, but the number of rotary louver plate groups may be any number as long as it is two or more. Further, the number of rotating louver plates forming each rotating louver plate group is also arbitrary.
It is possible to freely decide which rotary louver plate group is to be opened with a delay. Further, the delay angle of the rotary louver plate group that opens with a delay can be adjusted by changing the dimension of the elongated hole 11.

Further, in the above embodiment, the play portion of the connecting rod 8 is formed by the elongated hole 11, but it may be formed by a groove or the like. Also,
The long hole 11 may be provided in the louver fixing side member 8a, and the connecting piece 9 may be provided in the linking side member 8b.

[Effects of the Invention] As described above, according to the movable louver of the present invention, the rotary louver plate is divided into a plurality of rotary louver plate groups, and each rotary louver plate of the rotary louver plate group is connected by a connecting rod. Then
In addition, the connecting rods are linked to each other to be interlocked with each other by the operating rod, and the connecting rod of the specific turning louver plate group is configured by two members, a louver fixed side member and a linking side member, and a specific turning louver plate is provided between both members. Since the play portion for delaying the group is provided, it is possible to operate only the specific rotary louver plate with a delay from the other rotary louver plate groups, thereby closing only the specific rotary louver plate group. It is possible to obtain two effects, that is, a use mode in which the other rotary louver plate group is opened to ventilate in the open state and a use mode in which all rotary louver plates are vented to ventilate.

Further, since a spring for urging the specific rotating louver plate group in the delayed state is provided between the louver fixing side member and the linking side member, the specific rotating louver plate group is delayed. Thus, the rattling caused by the play portion when opened is prevented, and the stable operation is obtained.
