Description

[Detailed explanation of the invention] This invention relates to a rain-covering device for opening/closing windows.More specifically, it utilizes the principle of equal pressure to equalize the pressure inside the glass fitting groove of the shoji with the outside pressure, allowing rainwater to drain away. This invention relates to an improvement of a rain shutter device for an opening/closing window whose purpose is to prevent the intrusion of rain.

Rain closure devices that utilize the isobaric principle are well known for rain closure in general medium and high-rise buildings, but in conventional rain closure devices of this type, for example, when closing windows that open and close, To form an equal pressure space between a window frame composed of a vertical frame and a horizontal frame and a shoji fitted within this window frame, and make the inside of this equal pressure space equal to the outside pressure. This was to prevent rainwater from entering. Therefore, since the shoji itself is not provided with any kind of rain protection, there is a risk that rainwater may enter the glass fitting groove formed in the shoji stile, leading to the problem of rainwater entering the interior of the room. .

This invention was made with the intention of solving the above problem, and its main points are: a rectangular auxiliary frame that is fitted into the window frame; A first space is formed between the shoji stile and the four circumferential surfaces of the stile, and this first space is formed by a glass fitting groove of the shoji stile and a glass fitted into the glass fitting groove. The first and second spaces are connected to a second space in which the pressure is equal to the outside air pressure through outside air inlets bored in the vertical frame and the bottom frame of the auxiliary frame, respectively. This can prevent rainwater from entering the glass fitting groove.
The purpose of the present invention is to provide a rain closing device for an opening/closing window, which has features such as, even if rainwater enters the glass fitting groove due to capillary phenomenon, the entered rainwater can be discharged to the outside by the principle of equal pressure. be.

Examples of this invention will be described below based on the drawings.

FIG. 1 is a schematic front view of an opening/closing window having a rain protection device of this invention. In this case, the opening/closing window 1 is composed of a pair of left and right vertical frames 2, 2 and a pair of upper and lower horizontal frames 3, 3. It is composed of a rectangular window frame 4, a rectangular auxiliary frame 5 fitted within this window frame 4, and a glass shoji 6 fitted within this auxiliary frame 5. In this case, as shown in FIGS. 2 and 3, there is a tight fit around the outdoor end and the inner side of the outer side of the vertical frames 7, 7 and upper and lower frames 8, 9 that make up the glass shoji 6. Material attachment grooves 10a and 10b are formed, and two rows of tight materials 11 and 12 are attached to these attachment grooves 10a and 10b, respectively, between the shoji frames 7, 8 and 9 and the auxiliary frame 5. A first space 13 is formed that communicates with the four circumferences.
Furthermore, glass fitting grooves 15 are formed on the inner surfaces of the shoji frames 7, 8 and 9 by the shoji frames 7, 8 and 9 and the ridges 14 attached to the outdoor side of the shoji frames.
A glass 6a is fitted into the glass fitting groove 15 with a sealing material 16, and a second space 17 is formed which communicates with the glass fitting groove 15 all around the circumference. . The first space 13 and the second space 17 communicate with each other via outside air communication ports 18 bored in the shoji frames 7, 8, and 9 (however, they do not communicate with each other on the side of the upper frame). It is also possible to communicate with the outside air through outside air inlet ports 19 formed in the vertical frame 5a and the lower frame 5b of the auxiliary frame 5, respectively.

Note that tight material mounting grooves 10c are also formed on the indoor side ends of the outer surfaces of the shoji frames 7, 8, and 9, and the tight material 20 attached to the mounting grooves 10c and the tight material 12 form the auxiliary frame 5. A B space that communicates around the four circumferences is formed between the glass shoji 6 and the glass shoji 6, and this B space is connected to the four circumferences formed in the vertical frame 2 and the horizontal frame 3 through the outside air communication port 21 bored in the auxiliary frame 5. It communicates with space A, which communicates with vertical frame 2.
These spaces A and B are communicated with the outside air through an outside air inlet 22 provided in the horizontal frame 3.

As explained above, the rain closing device of this invention has two rows of tight materials 11 located indoors and outdoors between the shoji frames 7, 8 and 9 and the auxiliary frame 5 on the four outer peripheral surfaces of the glass shoji 6. , 12 to form a first space 13 that communicates with the four circumferences, and this first space 13 also has shoji frames 7, 8, and
The first and second The spaces 13 and 17 are communicated with the outside air through outside air inlets 19 formed in the vertical frame 5a and the lower frame 5b of the auxiliary frame 5, respectively, so that the insides of these first and second spaces 13 and 17 are It is formed so that the pressure is equal to the outside pressure. Therefore, the pressure inside the glass fitting groove, where rainwater could easily enter, is made equal to the outside pressure, making it possible to prevent rainwater from entering the glass fitting groove. Even if rainwater enters the glass fitting groove due to this phenomenon, it will not enter the indoor side any further and will fall due to its own weight within the glass fitting groove.
Drainage can be immediately drained outside. Furthermore, the first
Since the inside of the space is also at the same pressure as the outside air pressure, excellent effects such as promoting the waterproofing effect of the tight material on the outdoor side that makes up this first space can be obtained, so its utility value is remarkable. .
