2. Description of the Related Art Conventionally, as a waterproof louver installed in buildings, various factories, power plants, gymnasiums, warehouses, houses and the like, for example, wood, synthetic resin, metal or the like is used as a louver board. It is constructed by assembling in a frame body. In this case, the blades are usually installed in a lateral direction, that is, in a so-called multi-leaf box type.

[0003] When the direction of installation of the slats is set to such a lateral direction, it is possible to prevent wind and rain from entering from above or obliquely above, and to prevent the invasion of wind and rain from a lateral direction in a strong wind. To prevent the louver's original functions such as waterproofing, daylighting, ventilation and smoke exhaustion by effectively preventing the louver. Has been adopted.

[0004] However, a close observation of the type in which the wing plate material is installed in the horizontal direction, which has been traditionally taken halfway, shows that the wind water collected by each wing plate is successively arranged on the lower side. It has a weak point that it hangs down on the slats and scatters and easily enters the louver.In addition, the shielding effect against wind and rain from the left and right sides is not always sufficient, The problem was found to be particularly pronounced when the louver was large, as well as small.

The inventor of the present invention has laid out the blades not in the horizontal direction but in the vertical direction, and by adding some measures to the blades, all of the drawbacks of the conventional louver have been identified. Has developed a vertical waterproof louver that can effectively prevent rainwater intrusion, etc. (Japanese Patent Application No. 59-1)
No. 20688) and further refinement and study to make improvements and improvements. FIGS. 1A to 1C show an example thereof.
1 (a) is a cross-sectional view thereof, FIG. 1 (b) is a side view, FIG. 1 (c) is a front view, and FIG. 1 (b) and FIG.
(C) is shown in a reduced scale compared to FIG. 1 (a).

In FIG. 1, reference numeral 1 denotes a frame provided on the left side, and 2 denotes a frame provided on the right side.
_{1 to An} are arranged at equal intervals. Each of these blades A _1-
A _n consists of a strip-shaped plate body, adjacent to the vane plates mutually placed so as to overlap, each vane plates adjacent phase forms a space S ₁ to S _n, the Space S ₁
Ventilation through to S _n, performs flue gas, also causes the lighting or the like. Reference numerals 3 and 4 _denote frames provided on the upper end edge and the lower end edge of each of the slats A _{1 to An} , respectively, which are combined with the frames 1 and 2 on both the left and right sides. The assembled blade plates A _{1 to An} are fixed.

The lower edge side frame 4 is inclined downward toward the outside to allow rainwater to flow smoothly to the outside. As shown in FIG. 1 (a), the vane plates A ₁ to A _n are
It is formed of a band-shaped plate having a bent portion (bent portion) 5 and has a rectangular cross section. At the back of the bent part 5 is a protruding piece 6
The end of the protruding piece 6 is provided with a folded portion 7 provided outside, that is, toward the outdoor side. Turnback part 7
Is folded back into an appropriate shape such as an arc-shaped cross section.

[0008] Thus, it is possible to prevent the invasion of wind and rain from the outdoors to the indoors, receive raindrops here, collect the raindrops, and allow them to flow down. In this case, a groove is formed in the vertical direction by the back surface of the bent portion 5, the abdomen of the protruding piece portion 6 and the folded portion 7, so that the water collected here flows down. In addition, an arc-shaped bent portion 8 directed inward is provided at the outer edge of the rectangular band in cross section, that is, at the edge of the outdoor side, so that the pressure of wind and rain going from the outdoors to the indoors is reduced. In addition, the inner side edge, that is, the indoor side edge, which is shaped like a cross section, is provided with a wing plate extension 9.

The extension portion 9 extends a predetermined width in parallel with the protruding piece portion 6 and has a bent portion 10 bent at an end thereof into an inwardly arc-shaped cross section. Such an arc reduces the resistance of the air, thereby preventing any remaining raindrops from entering the room, and also catching the raindrops here, making them easier to collect and flow. Also, the blade A
_{1 to An} , the projecting portion 6, the folded portion 7, the bent portion 8, and the bent portion 9 are placed so as to overlap each other. This makes it possible to bend the course of wind and rain from the outside and prevent them from entering the room straight.

As shown in FIG. 1 (a), each of the blade plates A _{1 to An} is formed in a substantially obtuse cross-section at a substantially central portion in the width direction, and has a bent portion. 8
Is formed in an arc-shaped cross section, and the bent portion 10
In other words, the centrifugal force is applied to the air flowing through the louver, and the resistance of the flowing air can be greatly reduced. When the angle is almost a right angle, the aperture ratio is limited to at most 40%. However, in the louver of this example, the function as a waterproof louver,
While maintaining the function sufficiently, the aperture ratio is greatly improved.

[0011]

By the way, the above-mentioned blade plate is formed in a substantially obtuse angle cross section at a substantially central portion in the width direction and has excellent performance.
For example, the upper limit of the aperture ratio is around 50%. The present inventors have further studied and pursued the shape and structure of the wing plate in the vertical waterproof louver, and by pursuing this, by forming this into an S-shaped cross section in the width direction, the function and function as the vertical waterproof louver were obtained. It has been found that it can be maintained sufficiently and the aperture ratio can be further improved.

That is, the present invention relates to a vertical waterproof louver, wherein the blade plate member is configured so that its cross section in the width direction has an S-shape, and the function and action of the waterproof louver are sufficiently maintained. It is an object of the present invention to provide a vertical waterproof louver and a blade member for the vertical waterproof louver, which can further improve the rate to 65%. According to the present invention, it is possible to further improve the aperture ratio to not less than 50% and about 65%, as well as to set the aperture ratio to 30 to 50%.

BEST MODE FOR CARRYING OUT THE INVENTION A blade plate member according to the present invention is formed of a band-shaped plate body, and its cross section in the width direction is formed in an S shape. In the present invention, a plurality of the blade members are arranged in the vertical direction. However, since the blade members are configured in an S-shaped cross section in the width direction, the wind and rain from outside in the louver become S-shaped. Flows smoothly. The curve (slope) having an S-shaped cross section is appropriately selected. The curve is streamlined and aesthetically pleasing, but by making the slope gentle, the ventilation resistance can be reduced.

Since the blade member of the present invention has an S-shaped cross section in the width direction, two portions (bent portions) in the width direction are formed into a curved cross section or an arc cross section. These two
Protrusions are provided on the backs of the bent portions. Grooves are formed in the vertical direction by the abdomen of the protruding pieces and the back of the blade plate member, thereby preventing infiltration of wind and rain from outdoors to indoors, where raindrops can be received, collected and allowed to flow down.

According to the present invention, the S-shaped cross section not only sufficiently prevents rainwater from entering, but also sufficiently maintains functions and actions such as ventilation, smoke exhaustion, and daylighting. The aperture ratio can be increased to about 65%. In this regard, in the case of the above-described blade-shaped blade, the aperture ratio is limited to about 50%. To increase the aperture ratio, it is necessary to sacrifice the prevention of rainwater intrusion, for example.
ADVANTAGE OF THE INVENTION According to the S-shaped sectional board member of this invention, the opening ratio can be enlarged to about 65%, sufficiently preventing infiltration of rainwater. In the vertical waterproof louver of the present invention, the opening ratio can be set to about 50% to about 65%, but it is needless to say that the opening rate can be set to 30 to 50%.

In the present invention, a frame is provided on both the left and right sides and the upper and lower edges of the plurality of blade members. As a method of providing this frame, the plurality of blade members are assembled in advance using an appropriate holding member, and the frame is set on this. The appropriate holding of the plurality of blade members and the frame is performed. An appropriate method such as setting at once with a fixing member can be adopted. In any of these cases, by configuring the lower edge side frame of the frames so as to be inclined downward toward the outside, rainwater can smoothly flow out to the outside.
