Abstract

(57) [Summary] [Purpose] By arranging external louvers on the standard louver at regular intervals, irregular wind, rain, dust, etc. that roll up from any direction, especially horizontal and downward, will not enter the room. Ensure that it is protected and that it is very convenient to manufacture and install. [Configuration] A standard louver 4 including a stepped outer plate 1 and a downward plate 3 continuous with an end 2 of the outer plate 1, and a vertical plate 5 and an inner part continuous with an end 6 of the vertical plate 5. The rain louver is characterized in that an external louver 8 composed of an inclined plate 7 is connected and fixed between the downward plate 3 and the vertical plate 5 via a distance piece 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a rainproof louver.

[0002]

[Prior art]

 Conventional louvers are generally used in which a plurality of outer inclined plates are set at appropriate intervals and are attached to a window frame.

[0003]

[Problems to be solved by the device]

 According to the above-mentioned conventional technique, protection against wind and rain from directly above or diagonally above is provided, but wind and rain that rolls up from the horizontal direction or below it enters the room through the window with dust due to the irregular flow. I will get out. In other words, the louver according to the related art does not deal with wind and rain and dust from an irregular direction, and it cannot be said that the louver has fulfilled its function as a louver.

[0004]

[Means for Solving the Problems]

 In view of the problems associated with the above-mentioned conventional techniques, the present invention allows air flow to function freely as before, and can deal with wind, rain, dust, etc. that irregularly roll up from any direction, and , Was developed with the purpose of simplifying its manufacturing and construction.

In order to achieve this object, the gist of the present invention will be described using the reference numerals of the drawings corresponding to the embodiments. That is, the present invention provides a standard louver 4 consisting of an outer inclined plate 1 and a downward plate 3 continuous to an end 2 of the outer inclined plate 1, a vertical plate 5 and an end 6 of the vertical plate 5. It is a rainproof louver in which an outer louver 8 composed of a continuous inner inclined plate 7 is connected and fixed between the downward plate 3 and the vertical plate 5 via a distance piece 9. The standard louver 4, the external louver 8 and the distance piece 9 are integrally formed of steel, metal, synthetic resin, etc., and the lower end of the inner sloping plate 7 is a vertical plate 10 so that the downward plate 3 And a drop groove 11 is formed. Further, the distance piece 9 can be appropriately fixed with an adhesive, welding, bolts and nuts or the like.

[0006]

[Action]

 According to this plan, the air a in the room is changed downward while opening the window along the outer inclined plate 1 of the standard louver 4 and then upward along the inner inclined plate 7 of the outer louver 8. To be done. In addition, against the wind and rain from above and diagonally above, it is protected by the outer sloping plate 1 of the standard louver as before, and even if the window is opened, these will not enter the room. At this time, rain, dust and the like fall from the drop groove 11 along the outer inclined plate 1 and the inner inclined plate 7. The inner sloping plate 7 of the outer louver 8 protects wind, rain, dust, etc. from irregular directions such as rolling up horizontally and from below, and blocks these from passing through the window and entering the room. Such rain, dust, and the like hit the outer surface of the inner inclined plate 7 and sequentially fall from the drop groove 11 along the inner surface of the lower inner inclined plate 7. Therefore, in the state where the window is opened, the ventilation action of the exhaust air and the intake air in the room is smoothly performed, and at the same time, it is possible to prevent any wind, rain, dust, etc. from the outside from entering the room.

[0007]

Example 1 The standard louver 4, the outer louver 8 and the distance piece 9 were molded of a synthetic resin material in their respective molds. The distance piece 9 is formed by bending both ends 12 and 13 of a rectangular plate at right angles to each other and in different directions. Then, the distance piece 9 is interposed between the downward plate 3 of the standard louver 4 and the vertical plate 5 of the external louver 8, and the both ends 12 and 13 of the distance piece 9 are coated with an adhesive to form the standard louver 4. The distance piece 9 and the external louver 8 were connected and fixed in series. Therefore, as shown in each figure, the distance between the standard louver 4 and the outer louver 8 is maintained by the distance piece 9. This distance is determined by the length of the distance piece 9, but can be appropriately selected together with the inclination angles of the outer inclined plate 1 and the inner inclined plate 7 depending on the use conditions. Then, after installing the standard louver 4 on the window frame, the shower was evenly swirled and sprayed from an unspecified direction, and finely chopped paper was sprayed from the unspecified direction into a confetti shape using a fan. Water droplets 14 and confetti in this shower did not enter the room. These water droplets 14 and confetti fell from the drop groove 11 along the inner inclined plate 7 in the upper step to the drop groove 11 in the lower step. It should be noted that the smoke smoked by the window inside the room was directed downward along the standard louver 4 from the window and further upward along the external louver 8 and diverged to the outside.

[0008]

Second Embodiment The standard louver 4, the outer louver 8 and the distance piece 9 were molded by an aluminum material in their respective molds and applied, which was the same as in the second embodiment.

[0009]

[Effect of device]

 According to the rainproof louver of the present invention, it is the unique configuration in which the standard louver is connected to the external louver via the distance piece, and wind, rain, dust, etc. from the unspecified direction that rolls up from the horizontal or downward enters the room. It has the unique effect of being able to fully defend against this. Even if an external louver is attached, there is almost no pressure loss, so it has the same indoor ventilation function as the conventional standard louver alone. Furthermore, all components can be molded by die, which makes manufacturing and construction simple. An external louver can also be installed on the existing standard louver via a distance piece. At this time, when the opening ratio of the existing standard louver is small and the ventilation resistance is high, the opening ratio can be easily modified by cutting off a part of the existing standard louver.
