Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a movable louver that opens and closes by interlocking a large number of rotating louver plates.

[Prior Art and Problems to be Solved] Conventionally, in a movable louver arranged in a window opening of a building, a plurality of rotating louver plates are arranged in a vertical direction and each rotating louver plate is connected by a connecting rod. When the connecting rod is moved up and down by an operator, the rotary louver plate is interlocked to open and close.

However, in the above-mentioned conventional movable louver, since all the rotating louver plates are connected by a single connecting rod,
The rotating louver plates are evenly arranged to open and close. For this reason, there is a drawback in that it cannot be used to close a specific rotating louver plate and open only other rotating louver plates.

[Means for Solving Problems] In the present invention for solving the above-mentioned problems, in a movable louver that opens and closes by interlocking a large number of rotating louver plates, the rotating louver plates are appropriately grouped into a plurality of rotating louver plates. The rotary louver plates of the rotary louver plate group are respectively connected by connecting rods, the connecting rods of the rotary louver plate groups are linked by the interlocking rods, and are linked by the operating rods. Only the connecting rod of a specific rotating louver plate group is linked with the connecting rod of another rotating louver plate group by an interlocking rod having a delay play portion in the interlocking direction.

As shown in FIG. 3, it is formed in an elongated plate shape, and is rotatably connected to the tip of the supporting arm 3 of the rotary louver plate 1 of each rotary louver plate group 5, 6, 7. This connecting rod 10,11,12
Are arranged almost in a straight line.

As a result, when the connecting rods 10, 11, 12 are moved up and down, the rotary louver plate 1 is rotated and opened and closed about the shaft 4 in alignment with each of the rotary louver plate groups 5, 6, 7.

Next, the connecting rods 10 and 11 of the rotary louver plate groups 5 and 6 are linked to each other by the interlocking rod 14. The connecting rod 12 of the rotary louver plate group 7 is linked with the connecting rods 10 and 11 of the rotary louver plate groups 5 and 6 by two interlocking rods 15 and 16.

The interlocking rod 14 is formed in an elongated plate shape and jumps over the intermediate rotary louver plate group 7 to connect both ends thereof to the connecting rod 1.
It is rotatably connected to the lower and upper ends of 0 and 11.
By the linkage by the interlocking rod 14, the connecting rods 10 and 11 are interlocked with each other, so that the rotary louver plates 1 of the rotary louver plate groups 5 and 6 are simultaneously rotated and opened and closed. Further, both ends of the interlocking rod 14 are respectively formed with ring-shaped spacers 17a, 17b and
It is connected to the connecting rods 10 and 11 via 8a and 18b. As a result, the interlocking rod 14 has a spacer 17 as shown in FIGS.
They are arranged substantially parallel to the connecting rod 12 with an interval of a, 17b and 18a, 18b.

The interlocking rods 15 and 16 are located between the connecting rods 10, 11 and 12 and the interlocking rod 14, and one end side thereof is the spacers 17a, 17b and 1 respectively.
It is rotatably connected to 8a and 18b. Further, as shown in FIG. 3, connecting rods 10,1 are provided on the other end sides of the interlocking rods 15,16, respectively.
Long holes 15a and 16a of substantially the same length extending in the interlocking direction of 1 and 12 are provided, respectively. Then, the rotary louver plate group 7
To the sliding member 19 provided on the upper end of the connecting rod 12 of
The long hole 15a of 15 is slidably fitted, and the long hole 16a of the interlocking rod 16 is slidably fitted to the sliding member 20 provided at the lower end of the connecting rod 12. That is, the connecting rod 12 is the interlocking rod 15,1.
It is linked to the upper and lower connecting rods 10 and 11 through six elongated holes 15a and 16a.

Here, the long holes 15a and 16a of the interlocking rods 15 and 16 are positioned with respect to the sliding members 19 and 20 as shown in FIG. 2 when the rotary louver plate 1 is closed as shown in FIG. It is formed to have a relationship. That is, when the rotary louver plate 1 is in the closed state, the sliding member 19 is located in contact with the lower end of the elongated hole 15a, and the sliding member 20 is located in a position slightly slid upward from the lower end of the elongated hole 16a. There is. That is, the long holes 15a, 16a,
It functions as a delay play portion that delays vertical movement transmission of the interlocking rods 15 and 16 to the connecting rod 12.

An operator 21 for opening and closing the rotary louver plate 1 is provided below the indoor side of the right vertical frame 33, and an operating rod 22 of the operator 21 rotates via a link arm 23. It is connected to the connecting rod 11 of the louver plate group 6. The operating rod 22 rotates up and down by the operation of the handle 21a, and moves the connecting rod 11 up and down.

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

First, the operator operates the operator rod 21 with the rotating louver plate 1 of FIG.
And a connecting rod that is linked through the connecting rod 11 and the interlocking rod 14.
10 moves together and moves downward. As a result, the rotating louver plate group
The rotating louver plate 1 of 5, 6 rotates about the shaft 4 and gradually opens.

At that time, each rotary louver plate 1 of the rotary louver plate groups 5 and 6
However, the rotating louver plate 1 of the intermediate rotating louver plate group 7 is maintained in the closed state until the half open state as shown in FIG. Therefore, until the state shown in FIG. 4 is reached, ventilation is performed through the upper and lower rotary louver plate groups 5 and 6.

When the rotating louver plate groups 5 and 6 are in the half-opened state,
The upper end of the long hole 16a of the interlocking rod 16 comes into contact with the sliding member 20, whereby the connecting rod 12 moves downward together with the connecting rods 10 and 11. As a result, each rotary louver plate 1 of the rotary louver plate group 7 starts to rotate and open. Thereafter, when the operator 21 is further operated to rotate the operating rod 22 to the lowermost position, the rotary louver plates 1 of the rotary louver plate groups 5 and 6 are fully opened as shown in FIG. The rotating louver plate 1 of 7 is in a state of being slightly closed. In this way, the rotary louver plate 1 of the rotary louver plate group 7 opens later than the rotary louver plate 1 of the rotary louver plate groups 5 and 6 by the length of the elongated hole 16a of the interlocking rod 16. It is an operation.

Next, when the operating rod 22 is turned upward in the state shown in FIG. 5, the connecting rods 10 and 11 are interlocked and moved upward, so that the turning louver plates 1 of the turning louver plate groups 5 and 6 are closed. start. At this time, the rotary louver plate 1 of the rotary louver plate group 7 maintains the state shown in FIG. When the rotary louver plate 1 of the rotary louver plate groups 5 and 6 is rotated to the same position as the rotary louver plate 1 of the rotary louver plate group 7, the lower end of the long hole 15a of the interlocking rod 15 contacts the sliding member 19. They come into contact with each other, whereby the connecting rod 12 moves upward in conjunction with the connecting rods 10 and 11. After that, the rotating louver plate group 5, 6,
The rotating louver plate 1 of 7 simultaneously rotates to the closed state shown in FIG.

The connecting rods 10, 11, 12 and the interlocking rods 14, 15, 16 and the upper frame 31, the lower frame 32, and the vertical frame 33 are each formed by using an extruded mold material such as aluminum.

Although the rotary louver plate 1 is divided into the three rotary louver plate groups 5, 6, and 7 in the above embodiment, the number of rotary louver plate groups may be any number as long as it is two or more. The number of rotating louver plates forming the rotating louver plate group is also arbitrary. Further, which rotary louver plate group is to be opened with a delay can be freely determined by changing the linkage of the connecting rods. For example, in the case of the above-described embodiment, if the operating rod 22 is connected to the connecting rod 12, the rotary louver plate groups 5 and 6 can be opened with a delay.

Furthermore, although the case where the rotating louver plate 1 is formed of a glass plate is shown, it may be formed of, for example, metal or synthetic resin. Further, the connecting rods 10, 11 and 12 do not necessarily need to use the plate members shown in the drawings, and may use rod members, for example. The interlocking rods 14, 15, 16 are not necessarily required, and the connecting rods 10, 11, 12 may be directly linked to each other. In that case, the long holes are provided in the connecting rods 10, 11 and 12.

In addition, the delay angle of the specific rotating louver plate group that operates with a delay can be adjusted by changing the size of the associated elongated hole.

[Effect of the Invention] As described above, according to the rotary louver of the present invention, the rotary louver plate is appropriately divided into a plurality of rotary louver plate groups,
The rotating louver plates of the rotating louver plate group are connected by the connecting rods, the connecting rods are linked, and the operating rods are interlocked, and only the connecting rods of the specific rotating louver plate group are interlocked with the delay play part. By linking with the other connecting rod via the rod, it is possible to operate only the specific rotating louver plate group with a delay from the other rotating louver plate groups, so that only the specific rotating louver plate group is operated. Two types of usage can be obtained: a use mode in which the other rotary louver plate group is opened to perform ventilation in the closed state, and a use mode in which all rotary louver plates are opened to perform ventilation. .
