Description

[Detailed description of the invention] Skin protection! Horizontal roof installed for the purpose of ventilation! (Regarding.

Conventionally, louvers with blades attached to a frame with the outdoor side lowered have been widely used in buildings and other applications. Generally, a louver is made of flat blades with the outdoor side facing down and the indoor side tilting upward, and a plurality of flat blades attached to the frame body at regular intervals, and tilted in this way. Multiple layers are stacked at regular intervals to prevent rainwater from entering. It is true that most of the rainwater is prevented from infiltrating by the slope of this blade, but when the rainwater that hits the blade runs down the blade and falls from the side, the water droplets are sucked in by the air flow, etc. It seems that it is not possible to prevent a considerable amount of rainwater from entering.

SUMMARY OF THE INVENTION The object of the present invention is to provide a vent for use in a ventilation opening or an air suction opening that further reduces the infiltration of rainwater and the like.

Retsu (5) / 7-1 Okinaki The present invention is characterized in that the blades, which were conventionally attached to the frame horizontally, are tilted in the longitudinal direction.

In addition, in another invention, the plate is attached to the frame by tilting it in the same way, but it also uses a blade that has a gutter groove formed on its lower side to catch rainwater, etc. that falls down the plate. It is something to do.

FIG. 1 shows various usage examples of the entire louver of the present invention. Needless to say, the present invention is not limited to this, and may be modified as appropriate to match the design of objects such as buildings.

In both cases, upper frame 1. Bottom frame 2. The vertical frame 3.3 constitutes a frame body, and the plate plate 4.4 is mounted parallel to the frame body, tilting in the longitudinal direction. The direction of inclination is shown in the same figure (b) and (
As shown in c), either the left or right side may be facing up. Also,
Similarly, a vertical frame 3a may be provided in the middle, and two vertical frames 3a may be connected, or three or more vertical frames may be connected.

Since it is difficult to attach half-way printing plates to the top and bottom tiers, triangular blocking plates 5.5 are attached. In the same figure (d) and (e), the upper frame la, 4b
It goes without saying that if the lower frames 2a and 2b are inclined at the same angle as the plate 4, the closing plate 5 is not necessary.

In this embodiment, each member is made of extruded aluminum. The cross-sectional mj shape of the printing plate 4 is as shown in FIG. That is, the main body part 6 is obliquely formed in a flat plate shape, the inclined part 7 formed on the upper side thereof, the rising part 8, the water return part 9, and the falling part formed on the lower side of the main body part 6. 1o, and a protrusion 11. Although the sloped portion 7 is connected to the main body 8R6 and has a gentler slope than the slope of the main body 6, it is not necessary to form this slope, and the main body 4 may be extended as is. Further, the main body portion 6 does not necessarily have to be flat.

It may be formed to have an integral curve including a falling portion 10, an inclined portion 7, and a rising portion 8. In that case, it is natural that there will be no clear distinction between the main part, the standing part, etc. The water returning portion 9 protrudes at a substantially right angle at the tip of the rising portion 8'88, and this protruding portion catches raindrops flying horizontally under special conditions such as during a typhoon.

The protrusion 11 provided on the lower side of the plate 4 protrudes diagonally downward from the lower end of the falling portion 10, and gradually becomes thicker toward the tip, and the tip 12 is formed into an arc shape as shown in the figure. There is. This protrusion 11 may be made to protrude horizontally as shown in FIG. 3, or may be made to protrude obliquely upward as shown in FIG. These rising portions8. Mizukaeshi part 9, standing”-
The rib portion 1O1 protrusion 11 also serves to increase the rigidity of the plate 4. When projecting diagonally upward as shown in Fig. 4, it is desirable to omit the falling part lO.Furthermore, in the case of diagonally upward protruding, there is no need for the tip to be arcuate. Part 6, 17 Downward part 1
Do not let the water droplets fall directly onto this protrusion 1.
1. There is a device f for moving along an inclination that is received by lla and llb and attached to the frame of the plate. In addition, this is to increase the wetted area of the tip and make the water droplets grow larger and heavier (=J).

The plate 4 is attached to the frame using screw holes 13° 13. As shown in FIG. This allows it to be attached to the vertical frame 3. In this case, since the printing plate 4 is inclined in the longitudinal direction as described above, it is desirable to use a wedge-shaped washer 16 as shown in FIG.

FIG. 7 shows an embodiment of a printing plate 17 according to another invention.

Main body part 18, inclined part 19, vertical part 20, wood return part 2
The shape of No. 1 is no different from the one described above. The printing plate of this invention differs from the above-described one only in that gutter grooves 22 are provided on the lower side. Needless to say, this gutter groove 22 receives water droplets that flow down the main body portion 18.

The water droplets then pass through the gutter grooves 22 due to the inclination of the plate 17 and are drained to the outside from the longitudinal ends of the gutter grooves. Therefore, the end of the blade has the gutter groove 22 protruding from the tip as shown in FIG.
．． On the other hand, as shown in FIG. 9, it is preferable to cut the gutter groove 22 on the same plane as the main body of the blade, as shown in FIG. ing. At that time, it is desirable to provide a closing plate 24 at the end of the gutter groove 22.

In this way, if it is visually undesirable for the gutter groove 22 to protrude from the surface of the vertical frame 3, the first gutter groove 22 may be installed instead of the vertical frame 3.
It is desirable to use the vertical frames 25 and 26 shown in the θ diagram and Figure 11. The vertical frame 25 is used for the vertical frame on the lower side of the slope, and the vertical frame 26 is used for the vertical frame on the upper side of the slope. It is. That is, the vertical frame 25 is formed into a cross-sectional shape having a vertical groove 27 into which the protruding tip of the gutter groove 22 can be inserted, and the vertical frame 26 is shaped until its outdoor side surface 27 is in a position to cover the gutter groove 22. The cross-sectional shape is formed by extending the side surface 28. In this case, the side surface 28 also serves as the closing plate 24, so there is no need for a closing plate.In this embodiment, the gutter groove 22 has its tip protruding, but it is not necessarily necessary to make it protrude.

Moreover, the vertical frame 29 shown in FIG. 12 is used as the intermediate vertical frame 3a for constructing the blade 17 having the gutter groove 22 as shown in FIG. 1(c). This vertical frame 29 has a symmetrical cross-sectional shape, and has an indoor surface 30 and a blade 17.1 connected thereto.
7, a connecting plate 32 connecting the two side surfaces, and a partition plate 34 connecting the outdoor surface 33 to the connecting plate 32. Said side faces 31.31 are spaced apart from the surface 33 so that the gutter groove 22 of the vane 17 can be inserted between them. That is, the surface 33, the partition plate 34, and the connecting plate 32 constitute a downspout similar to the downspout 27 described above. In order to access the blades 17 to this intermediate vertical frame 29, since they are mounted on the inside, they cannot be simply attached with screws, and as shown in the figure, fixtures 35 and 35 are used.

When using the blade 4 shown in Figure 2, 5 the main body part 6 of this blade 4.
, rainwater falling on the falling portion lO turns into water droplets and falls on the protrusion 11 along each of them. At this time, since the blades 4 are inclined in the longitudinal direction, the water droplets descend while facing downward. The speed of the water droplets differs depending on the droplet, and the timing of the drop is inconsistent, so as they descend, nearby objects stick together, merge, and the droplets gradually grow larger.
It gets heavy. While moving along the slope in this manner, the water droplet becomes larger and heavier until it reaches the tip of the protrusion 11.

Furthermore, as shown in FIG. 13, this water droplet wraps around under the tip 12, but due to the adhesive force of the water droplet, it does not fall immediately, but flows down along the longitudinal direction Ill of the blade, reaching the lowest end in this inclined direction. Or, it falls when it merges with other water droplets and the force of gravity becomes greater than the adhesive force of the water droplets. If the tip 12 is made into a large arc shape as in this embodiment, the water droplet will have a large entwined area and will have a large adhesive force, so the water droplet will not fall until it becomes larger.

Even when a water droplet falls without reaching the lower end of the longitudinal direction of the slope, the water droplet is accelerated in the direction of the slope as it flows down along the blade, so it falls with kinetic energy.

When it rains heavily, the amount of water droplets increases, and as they flow diagonally down the blades 4, they merge to form a continuous flow.

In any case, in the case of this embodiment, the water droplets either fall from the end of the blade in the inclined direction, or when the water droplets flow down the protrusion 11 in the inclined direction, the water droplets merge with each other and become relatively large before falling. Therefore, even if the falling water droplet is heavy and falls before reaching the bottom end of the blade's longitudinal tilt 1, it will fall with energy in the falling direction, so it will pass between the plates. It never takes on air.

Therefore, in the case of this embodiment, it is possible to further reduce the amount of rainwater sucked into the room.

On the other hand, when the blades are simply installed horizontally in the longitudinal direction, as in the past, the water droplets that fall down the blades do not merge with nearby water droplets, and the water droplets are large. It will fall before it happens. In addition, even if the water droplets that fall later merge with the water droplets that fall and become large S water droplets, the interlocking energy in the falling direction is zero, so the water droplets ride on the air flow passing between the blades. It gets sucked in.

The same applies to the case of using the blade shown in FIG. 3 in which the protrusion 11a is made perpendicular.

In the case where the protrusion 11b is formed obliquely upward as in the example shown in Fig. 4, a groove is formed by the protrusion llb and the main body part 6, so water droplets coming down from the main body pass through this groove. Then, it moves along the slope to the end of the blade and falls at the end.

If water droplets are allowed to fall at the lower vertical frame 3, they will fall in a straight stream and there is no risk of being sucked in.

Further, in the case of the blade 17 having a gutter groove 22 as shown in FIG. 7, rainwater flows into the gutter groove 22 and the blade 1
7 slope, and the water is reliably drained outside the vertical frame, so there is little risk of rainwater being sucked in.

As explained in detail above, according to the present invention, since the blades are attached to the frame at an angle, rainwater droplets that fall on the blades collect while falling due to the slope of the blades, and are more Since the water droplets become large and heavy and fall with increased energy in the falling direction, they are carried by the air passing between the blades and do not reach the room. Therefore, according to the present invention, infiltration of rainwater can be further reduced.

In addition, in the second invention, rainwater that hits the blade falls into the gutter,
The inclination of the blades allows water to drain to areas other than the areas where the blades are attached, so most rainwater can be prevented from entering.
