That is, as shown in FIGS. 2 and 3, the wind and rain that is strongly blown from the outside is distributed to the left and right by the wall plate 16 located on the front side of the first blade plate 3, and the distributed rainwater is provided to the left and right. The bulging portion 14 can be wound around and guided to the inner side surface 30 of the first blade plate 3.

Then, the rainwater guided to the inner side surface 30 flows along the inner side surface 30 and hits the inside of the winding piece 15 located at the left and right tips on the back side of the first vane plate 3, and the rainwater is guided by the winding piece 15. It is drained and can be dropped.

By the way, a part of the rainwater that has passed over the winding piece 15 is taken up along the curved outer surface of the winding piece 15 and guided to the wall plate 17 on the back side, but the momentum is weakened. It can be dropped on the surface of the wall plate 17.

The rainwater flowing along the inner side surface 30 of the first blade 3 weakens its flow force by the mountain-shaped protrusions 19 provided in the vicinity of the winding piece 15 on the inner side surface 30. At the same time, the force applied to the inner side of the winding piece 15 is also the same, so that it can be prevented from scattering.

Next, the wind and rain which is strongly blown from the outdoor side, which hits the crescent-shaped protrusion 24 which is curved inward and which is provided at the apex 23 located on the front side of the second blade 4, is shown in FIGS.
As shown in FIG. 3, the protrusions 24 distribute the light to the left and right, and flow vigorously along the curved side 20 facing the front side, and are guided to the apexes 21 located on the left and right. And vertex 21
The rainwater guided to the top has a vertical waterproof and soundproof louver 1 at the top 21.
Since it is formed to be bent so as to face the front side of the first blade plate 3, it bounces up at the bent portion and is scattered on the inner side surface 30 of the adjacent first blade plate 3 to flow along the inner side surface 30 and It hits the inside of the winding piece 15 located on the back side of the one blade 3, and the water can be drained by the winding piece 15 and dropped.

Part of the rainwater that has passed over the vertices 21 located on the left and right flows along the side 20 located on the back side that is curved and curled up behind the vertices 21, and the second blade 4 When it hits the inner side surface of the crescent-shaped projection piece 24 provided at the apex 21 located on the back side of, it can be dropped along that surface.

Further, the blind plates 26 provided on the left and right inner side surfaces of the frame body 2 receive the rainwater scattered at the apex 21 of the curved front side 20 of the second vane plate 4, and the received rainwater is the above-mentioned. It can be dropped along the surface of the blind plate 26.

As described above, the first vane plate 3, the second vane plate 4, and the blindfold plate 26 can reliably prevent rainwater from entering the indoor side, and at the same time, the ventilation gap 1 only.
You can enter from 2, 29.

By the way, the rainwater that has dropped on the surfaces of the first blade plate 3, the second blade plate 4 and the blind plate 26 in the above is provided on the upper surface on the indoor side of the lower horizontal rail 6 which constitutes the frame body 2. By the vertical piece 6d, it is possible to prevent the intrusion into the indoor side.

Further, the apexes 21 located on the left and right of the second vane plate 4 are the bulging portions 14 provided on the left and right ends of the adjacent first vane plates 3 facing the front side of the vertical waterproof and soundproof louvers. Since it is located on the inner side of the line 22 connecting the winding pieces 15 provided at the left and right ends facing the back side, that is, near the first blade plate 3, wind and rain from the outdoor side is above the second blade. The plate 4 can be prevented from coming out indoors, and formed so that the indoor side cannot be directly seen through the ventilation gap 12 between the first blade 3 and the second blade 4. can do.

Further, the noise from the outdoor side is similar to that of rainwater, and a large number of first blades 3 are alternately arranged in a row in the frame 2 in the frame 2.
Is formed between the first vane plate 3 and the second vane plate 4 after being weakened in a one-cushion manner by strongly hitting the second vane plate 4 and the blind plate 26 and detouring. Since the air enters the indoor side through the ventilated gaps 12 and 29, a soundproofing effect is obtained.

[0031]

As described above, according to the vertical waterproof soundproof louver according to the present invention, the wind and rain that is strongly blown from the outdoor side are alternately arranged in the frame in the first blade plate and the second blade plate. After being strongly struck against the blade plate of No. 1, rainwater drops along the surfaces of the first blade plate and the second blade plate, and only wind is blown on the first blade plate and the second blade plate. It can be introduced into the indoor side by passing through the ventilation gap formed between.

Further, rainwater can be guided to the inner side surface of the first vane plate by the bulging portions provided at the left and right front ends of the first vane plate, and the inside provided at the left and right tip ends on the back side. Rainwater that has flowed along the inner surface can be cut off and dropped by the winding piece that has been wound around.

Further, the left and right vertices of the second blade plate are on the line connecting the bulging portions provided at the front and left ends on the front side of the adjacent first blade plates and the winding pieces provided at the left and right ends on the back side. Since it is located inside the room and is bent so as to face the front side of the vertical waterproof soundproof louver, the wind and rain that blows strongly from the outdoor side is distributed to the left and right by the apex along the curved side of the front side. The rainwater that flows vigorously and is guided to the vertices located on the left and right, and the rainwater guided to the vertices is bent so that the vertices face the front side of the vertical waterproof and soundproof louver, so jump up at this part. It can be scattered on the inner surface of the adjacent first blades.

Then, the scattered rainwater flows along the inner side surface and hits the inside of the winding piece located on the back side of the first blade plate, and the water is drained by the winding piece and can be dropped.

Furthermore, the left and right vertices of the second blade plate connect the bulging portions provided at the front and left ends on the front side of the adjoining first blade plates and the winding pieces provided at the left and right ends on the back side. Since it is located inside the line, it can prevent wind and rain from the outdoor side from passing through the ventilation gap and directly to the indoor side, and also prevent looking into the indoor side directly from the ventilation gap. can do.

Further, noise from the outdoor side strongly hits the first blade plate and the second blade plate, which are alternately arranged in a row in the frame alternately in the same manner as rainwater, bypasses them and weakens with one cushion. After the state, since it enters the indoor side through the ventilation gap between the first blade and the second blade,
This provides a soundproofing effect.
