[Technical field to which the invention belongs]

 The present invention relates to a vertical waterproof louver that can be appropriately installed in buildings, various factories, power plants, gymnasiums, warehouses, houses, etc. More specifically, the vertical waterproof louver has a significantly improved lighting performance. Type waterproof louver.

[0002]

[Prior art]

 Conventionally, as louvers installed in buildings, various factories, power plants, gymnasiums, warehouses, houses, etc., for example, wood, synthetic resin, or metal blades are used, and they are assembled in a predetermined frame. It is composed of In this case, the vane plate material is normally installed in the lateral direction, that is, in the form of a so-called hundred-leaf box. By setting the installation direction of the blade plate in such a lateral direction, it is possible to prevent wind and rain from above or obliquely above, and to prevent wind and rain from entering in the lateral direction during strong winds, and also to allow sunlight to enter directly. By preventing this, the functions and functions of the louver's original waterproofing, lighting, ventilation, smoke emission, etc. are fulfilled.

However, when observing the louvers of the type in which the vane plate material is installed in the lateral direction, which has been traditionally taken in such a way, the rainwater collected by each vane plate is sequentially collected on the lower side. It has a weak point that it hangs down on the blades and scatters and easily enters the louver.The shielding effect against wind and rain from the left and right lateral directions is not always sufficient, and the shielding from the left and right lateral directions. It turns out that the problem becomes noticeable when the louver becomes particularly large.

The present inventor adds some measures such that the vane plate is installed vertically instead of laterally, and the vane plate is formed into a V-shaped cross section. As a result, we have developed a vertical waterproof louver that can efficiently prevent the invasion of rainwater, etc., which has solved all of the above drawbacks of conventional louvers (Japanese Patent Application No. 59-120688) and further research. , Making improvements. These vertical waterproof louvers can completely or almost completely prevent the infiltration of raindrops even during strong wind and rain such as a typhoon, and can also reduce the wind pressure toward the inside of the building. It has been adopted successively at various facilities.

By the way, the vertical waterproof louver is installed in various facilities such as buildings, various factories, power plants, warehouses, houses, etc., through which ventilation, smoke emission, daylighting, etc. are performed. In addition to natural ventilation, a fan is usually used for this, and power is used for this. In any of these cases, it is necessary to reduce the resistance of the air flowing through the louver as much as possible in order to fully perform its functions such as ventilation. The aperture ratio must be increased as much as possible after maintaining it sufficiently.

However, the aperture ratio, that is, the ratio of the air circulation surface to the entire surface of the louver is usually around 30%, and even if various parts are devised, it is at most around 40% and exceeds this value. There is no choice but to make the angle of the V-shaped section of the blade plate larger than 90 °, and then the original function of the louver, that is, the function, operation and effect of preventing the intrusion of rainwater cannot be maintained.

FIGS. 1A to 1C are views showing an example of a vertical waterproof louver that solves the above problems. Of these, FIG. 1 (a) is a cross-sectional view, FIG. 1 (b) is a side sectional view, and FIG. 1 (c) is a front view, and FIGS. 1 (b) and 1 (c) are compared with FIG. It is shown in a reduced size. In FIG. 1, 1 is a frame body provided on the left side, and 2 is a frame body provided on the right side, and a plurality of blades A _{1 to} A _n are arranged at equal intervals therebetween. The vane plates A ₁ to A _n consists of a strip-shaped plate member, each adjacent vane plates are placed to overlap each other, the space S ₁ to S _n in each vane plates adjacent phase The space is formed, and ventilation and smoke are exhausted through the spaces S _{1 to} S _n , and lighting is performed.

Reference numerals 3 and 4 _denote frame bodies provided at the upper and lower edges of the blades A _{1 to} A _n , respectively, and these are in cooperation with the frame bodies 1 and 2 on the left and right sides, respectively. In the case of the example, the blade plates A _{1 to} A _n , which are integrally assembled in advance, are fixed. Although the lower edge side frame 4 may be horizontal, it is preferable that the lower edge side frame 4 be inclined downward toward the outdoor side so that rainwater can be smoothly discharged to the outside.

As shown in FIG. 1A, each of the vane plates A _{1 to} A _n is composed of a strip-shaped plate body having a bent portion (bent portion) 5 and has a V-shaped cross section. The bent portion 5 has a projecting piece portion 6 on its back, and the tip portion of the projecting piece portion 6 has a folding portion 7 provided outwardly, that is, toward the outdoor side (its shape is an appropriate shape such as a circular arc cross section) However, in the present specification, the “folded portion” is referred to including such a shape). These prevent wind and rain from entering from the outdoors to the inside, where raindrops can be received, collected, and made to flow down.

In this case, a groove is formed in the vertical direction by the back surface of the bent portion 5, the abdominal portion of the protruding piece portion 6 and the folded portion 7, whereby the water collected here flows down. At the outer edge of the V-shaped cross section, that is, at the outdoor side edge, an inward arcuate bent portion 8 (the shape of which is an appropriate shape such as an arcuate cross section, In the present specification, the “bent portion” is referred to inclusive of such a shape), so that the pressure of wind and rain traveling from the outdoors to the interior is relaxed, and the cross-section The inner edge portion of the shape, that is, the indoor side edge portion is provided with a blade plate extension portion 9.

The extension portion 9 extends a predetermined width in parallel with the projecting piece portion 6, and has an end portion provided with a bent portion 10 that is bent inward toward a circular arc of a cross section. Such an arc reduces the resistance of the air, thereby preventing the entry of residual raindrops into the room and also catching the raindrops here, collecting them and making them easier to flow. Here, the extension portion 9 forms a part of the bending portion 10, and the extension width thereof is not always essential, and the extension portion 9 may be bent from the root of the blade plate. In addition, the blade plates A _{1 to} A _n , the protruding piece portion 6, the folded portion 7, the bent portion 8 and the bent portion 9 are preferably arranged so as to overlap each other. This can bend the path of wind and rain from the outdoors and prevent them from entering the straight inside.

Further, if the raindrops intrude (intrude) from the outdoors to the indoors can be prevented by the back surface of the bent portion 8, the abdomen of the projecting piece portion 6 and the folded portion 7 at a normal wind and rain, By providing the extension portion 9 and the bent portion 10, it is possible to almost completely prevent the intrusion of raindrops even in the case of strong wind and rain such as a typhoon, and change the wind direction toward the inside to soften the wind pressure. As shown in FIG. 1 (a), each of the vanes A _{1 to} A _n has a substantially obtuse cross-section with a substantially obtuse angle, such as approximately 105 ° to 130 °, in the substantially central portion in the width direction thereof. This is because the bent portion 8 is formed in a circular arc cross section and the bent portion 10 is preferably formed in a circular arc cross section. ing.

In addition, in the example of FIG. 1, in addition to the above-mentioned characteristic part, by providing the characteristic part and, the centrifugal force is applied to the air flowing through this louver, and the resistance of the circulating air is significantly reduced. You can As mentioned above, when the angle is set to a substantially right angle, the porosity is limited to around 30% and at most 40%. However, in this example, by providing these characteristic parts and The porosity is greatly improved while maintaining the function and action as a waterproof louver even if the angle of the V-shape is widened significantly.

By the way, in the vertical louver of the above-mentioned type, although the porosity is improved and the light-collecting property is also considerably improved, it is not always sufficient to obtain the light to the indoor side through the louver. The porosity is approximately proportional to the lighting performance (that is, the larger the porosity, the more the lighting performance is improved in proportion to it). However, the porosity is almost the limit at around 50%. . To further increase the porosity and daylighting properties, for example, by setting the angle of the vane plate member with a V-shaped section to an obtuse angle exceeding 130 °, it is possible to prevent the intrusion of raindrops during strong wind and rain such as typhoons. There is no choice but to sacrifice the functions of the louver itself, such as easing and wind pressure reduction.

[0015]

[Problems to be Solved by the Invention] Therefore, the present invention has been made in order to solve the above-mentioned various problems relating to the daylighting property. In the vertical waterproof louver in which the blade is vertically installed, In addition, by adding a great deal of extra effort to the configuration of the blade plate members, the function as a vertical waterproof louver is maintained as it is, while the lighting performance is greatly improved, and the lighting performance can be freely set and selected. The purpose is to provide a type waterproof louver.
