DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a watertight structure of a sliding window.

[0002]

2. Description of the Related Art In a sliding window, an upper frame of a shoji is used.
The lower frame, the door stop frame and the upper frame of the window frame, the lower frame, and one of the vertical frames are water-tight with a water-tight material, and the upper frame of the outer door, the lower frame, the door frame and the upper frame of the window frame, the lower frame Frame, the other vertical frame is watertight with a watertight material,
The space between the inner frame and the outer frame is watertight with a watertight material.

[0003]

In the sliding window having the above-mentioned watertight structure, rainwater infiltrates into the indoor side from each watertight part or the glass mounting gasket portion of the inner sash in the case of a strong storm such as a typhoon, and the rainwater falls. If rainwater accumulates between the frame and the inner side of the lower frame of the outer door, and continuous rainwater enters for a long time, the water level of the rainwater collected between the lower frame and the inner side of the lower frame of the outer door may increase. Yes, in that case, it may flow into the room over the room-side rising portion of the lower frame.

Accordingly, an object of the present invention is to provide a watertight structure of a sliding window capable of solving the above-mentioned problem.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a window frame 1 has an upper frame 2, a lower frame 3 and left and right vertical frames 4 in a rectangular frame. An inner sash 5 and an outer sash 6 are attached to the window frame 1 in the out-of-plane direction and inward of the out-of-plane direction to form a sliding window.

The inner sash 5 and the outer sash 6 have a glass 15 mounted in a frame assembly 14 in which an upper frame 10, a lower frame 11, a door stop frame 12, and a combination frame 13 are assembled in a square frame.

As shown in FIGS. 2 and 3, the upper frame 10, the lower frame 11 and the door frame 12 of the inner shoji 5 are provided with inner and upper horizontal watertight materials 2 as shown in FIGS.
0, an inner lower horizontal watertight material 21 and an inner vertical watertight material 22 are mounted, and these watertight materials are an inner upper rail 2a of the upper frame 2, an inner lower rail 3a of the lower frame 3, and an inward piece 4a of one of the vertical frames 4. To each other.

The upper frame 10 of the shoji 6 has an outer upper horizontal watertight material 23.
The watertight material is pressed against the outer upper rail 2b of the upper frame 2. The outer vertical watertight material 24 is provided on the inward piece 4 b of the other vertical frame 4, and the outer vertical watertight material 24 is
(2) Crimp on the side of the room. Attachment 25 is attached to lower portion of lower frame 3 below inner lower rail 3 a with screw 26, and outer lower horizontal watertight material 27 provided on this attachment 25.
Is crimped on the inner side surface of the lower frame 11 of the shoji 6. The area between the mating frame 13 of the inner sash 5 and the mating frame 13 of the outer sash 6 is watertight with a sealing watertight material 28.

The upper frame 10, the lower frame 11, the door stop frame 12,
The combination frame 13 of the inner shoji 5 is made of a metal outdoor member 10a,
11a, 12a, 13a and indoor side member 10 made of heat insulating material
b, 11b, 12b, and 13b.

As described above, the space between the lower frame 3 and the inner side of the lower frame 11 of the outer sash 6 is watertight with the outer lower horizontal watertight material 27, and the space between the lower frame 11 and the lower frame 3 of the inner sash 5 is formed. Is watertight by the inner and lower watertight material 21. The watertight portion between the lower frame 11 and the lower frame 3 of the outer sash 6 is located below the watertight portion of the lower frame 11 and the lower frame 3 of the inner sash 5.

As shown in FIG. 4, the heat-insulating indoor side member 11b of the lower frame 11 of the shoji 6 is hollow, and the lower end thereof is the upper end of the outer lower rail 3b of the lower frame 3 and the outer lower side. Watertight material 2
7, the outer lower lateral watertight material 27 is located above the upper end of the outer lower rail 3b.

A hollow portion 30 of the indoor side member 11b made of a heat insulating material of the lower frame 11 of the outer sash 6 is opened downward by a drain hole 31 formed at a lower end thereof. The indoor-side rising portion 3 of the lower frame 3 at a position above the horizontal watertight material 27
c, It opens to the indoor side as a position below the upper end of the inner lower rail 3a. A drain valve 33 is attached to the hole 32.

The drain valve 33 includes a cylindrical valve body 34 and a valve 35 slidably mounted on the valve body 34.
5 is closed by its own weight and is opened by swinging to the outdoor side. A valve body 34 is fitted and mounted in the hole 32.

[0016] As described above, as shown by a broken line in FIG. 4, the space between the inside of the lower frame 11 of the shoji 6 and the inner lower rail 3 a of the lower frame 3 and the attachment 25 (that is, lower than the lower frame 11). When the water level of the rainwater accumulated in the part closer to the inside of the room rises, the valve 35 of the drain valve 33 is swung to the outside by the head pressure and is opened, and the accumulated rainwater flows into the hollow portion 30 and drains from the drain hole 31. Is done.

For this reason, the water level of the rainwater accumulated in the above-mentioned portion is up to the maximum drain valve 33, and does not become higher than the inner lower rail 3a and the indoor rising portion 3c of the lower frame 3, so that the indoor level of the lower frame 3 It does not flow to the indoor side beyond the rising portion 3c.

The rainwater that has flowed in over the outer lower rail 3b accumulates closer to the room than the outer lower rail 3b, but the water level is up to the upper end of the maximum outer lower rail 3b. The maximum level of the rainwater that has entered the part 30 is located below the drain valve 33. This prevents rainwater from flowing backward from the drain valve 33 to the indoor side.

When rainwater does not accumulate in the indoor portion of the lower frame 11, the drain valve 33 is in a closed state, and the outside air pressure acting on the hollow portion 30 through the drain hole 31 causes the outdoor wind pressure. The air does not enter the room through the drain valve 33, and the airtightness can be maintained.

In the above embodiment, the indoor side member 11b of the lower frame 11 is made of a heat insulating material, but may be made of a metal. Also,
The lower frame 11 has an integral shape with a hollow part on the indoor side
It is good.

[0021]

According to the first aspect of the present invention, the outer shoji
Rainwater collected in the part closer to the room than the lower frame is drain valve, hollow part
Is drained from the drain hole through
The maximum level of rainwater that accumulates on the side is the rising part of the lower frame on the indoor side
Lower than the lower frame, which flows over the indoor rising
Never be. Also, the lower part of the lower frame is closer to the room
Since the maximum level of rainwater that accumulates is lower than the drain valve,
There is no backflow from the valve to the part closer to the room. Also, drain
Outdoor wind pressure that flows into the hollow part from the borehole acts on the drain valve
Then, it will be in the closed state, so air will immerse into the room from the drain valve
Airtightness can be maintained without entering.
