Description

[Detailed explanation of the idea] [Purpose of invention] [Industrial application field] This invention relates to the gaskets for casement windows on both sides.

[Prior art] Conventionally, in a double-hung window, the inner side surface of the stile of the opening shoji is pressed against the gasket that surrounds the four circumferences of the window frame and is fixed to the window frame, and the gasket that is fixed to the upper frame of the window presses against the gasket that is fixed to the window frame. Place it in contact with the top surface of the upper stile of the double-door shoji,
Airtightness and watertightness were maintained between the window frame and the double-hung shoji by placing a seal between the inner sides of the stile.

[Problem that the invention aims to solve] Wind containing rainwater blows between the vertical frame of a window that opens on both sides and the vertical stile of the shoji screen, and blows in from between the inner circumference of the vertical frame and the outer periphery of the shoji screen, causing the window frame to Wet the outside side of the gasket installed between the inside surface of the shoji frame and wet the outside side of the gasket, and if there is a place where the gasket has poor adhesion, the rainwater near that defective place will be pushed due to the pressure difference between the air pressure on the outside side, which is greater than the air pressure on the inside side. Rainwater seeps into the interior through defective parts of the packing.

Also, when I opened the shoji, water droplets near the padskin surrounding the window frame sometimes fell onto the nape of my neck protruding from the window.

This idea took into consideration the above problems, and was designed to prevent rainwater from entering between the window frame and shoji of a double-hung window, and water droplets falling down the sill and window frame when the shoji is opened and closed. The purpose of the present invention is to provide a casement window on both sides without the need for a window.

[Means for solving the problem] This idea is to surround the window frame with a gasket that comes into contact with the inside surface of the stile of a double-hung shoji shoji, and a gasket that seals between the inside sides of the stile is combined. At the same time, a gasket is provided on the stile, and a gasket is provided between the upper stile and vertical stile of the shoji and the upper frame of the window frame and the vertical frame at a position on the outside of the gasket, and a gasket is provided on the stile to seal the space between the stile. This is a window that opens on both sides to form a labyrinth by hanging the outer members of the shoji so as to overlap the water return members of the lower frame.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings.
FIG. 1 shows a front view of a double-hung window in which this invention is implemented, viewed from the inside. Vertical frame 1, upper frame 2,
Shoji 4, 4 that opens outward on a window frame with a lower frame 3 assembled on all sides
It is equipped with a casement window on both sides.

Figure 2 is an enlarged longitudinal sectional view taken along line A-A in Figure 1;
4 shows a part of an enlarged sectional view taken along the line BB in FIG. 1.

The upper frame 2 extends outward from the indoor side inner circumferential member 7 by a step member 8 to constitute an outer side inner circumferential member 9, and the step member 8 is provided with a groove 10. The lower frame 3 has a step member 12 hanging from the end of the indoor side inner circumferential material 11 more than the step member 8 of the upper frame toward the indoor side, and a water return 14 is further hung from the end of the outer side inner circumference material 13 with a water slope. It continues to the water gradient member 15. The step member 12 has grooves 1 that open toward the outside.
0 is set. In the vertical frame 1, a protrusion 17 is provided on an inner circumferential member 16 extending toward the inside and outside, and a protrusion 17 is provided toward the inside of the opening.
A groove 10 that opens toward the outside is provided at the 7th end. The grooves 10 of the upper frame 2, lower frame 3, and vertical frame 1 are located at the same position in the internal and external directions, and the grooves 10 have the upper frame 18,
Lower stile 19, vertical stile 20, side stile 21, or 2
A packing 22 is fitted in contact with the inside of each stile of the shoji 4, which is made up of four shoji 1'.

A groove 2 is provided at the outer end of the outer inner peripheral material 9 of the upper frame 2.
3 is provided, and a packing 25 is fitted into the groove 23, the fins of which are in contact with the end of the outer material 24 of the upper stile 18 of the shoji 4, or are located on the outer side at a very slight distance therefrom. The inner member 26 and outer member 24 of the upper stile are connected by a horizontal member 27. Therefore, a space 28 surrounded by the outer inner peripheral material 9 of the upper frame 2, the inner material 26 of the upper stile 18 of the shoji 4, the horizontal member 27, the outer material 24, and the packings 22, 25 is formed in the upper part. .

The inner and outer members 29 and 30 of the vertical frame 20 of the shoji 4 are connected by a vertical member 31, and the outer member 30 and the vertical member 31
At the corner where the two meet, there is a groove 32 that opens toward the inside.
A gasket 34 is fitted into the groove 32 so that its fins contact the inner peripheral material 16. The connecting frames 21 and 21' have the same structure as the vertical frame 20, and the same parts are given the same reference numerals. Only the different parts will be explained. A binding frame 2 facing the binding frame 21 is attached to the protrusion 33' of the binding frame 21.
A blindfold material 35 is provided to cover the distance between 1' and remove water.

A mounting plate with a hinge 36 is fixed to each of the vertical frames 1 facing the vertical stile 20, and a gasket 34 and a protrusion 33 are cut out by the size of the mounting plates. The end of the gasket 34 coincides with the fin end of the gasket 25 provided on the upper frame.

A vertical space 37 surrounded by the inner peripheral material 16 of the vertical stile, the protrusion 17, the vertical member 31 of the vertical stile 20, the end of the inner material 29, and the packings 22 and 34 communicates with the upper space 28, and a gate-shaped space is formed. configured.

The outer material 38 of the lower stile 19 hangs down, and the water return 14
and the ends thereof face each other, and the inner member 39 and the outer member 38 are connected by a horizontal member 40. The end of the outer inner circumferential member 13 of the lower frame 3 is formed into a roughly inverted L-shaped protrusion that protrudes outward from the water return 14. The strip 41 is for the tapping hole, but it also strengthens the water return and also serves as the outer material 3 of the lower stile 19.
8 to form a narrow air passage. Therefore, a maze-like space 42 is formed between the lower stile 19 and the outer side of the lower frame 3, the space 42 communicates with the outside, and the vertical frame 1 and the vertical stile 20,
It communicates with the space 37 between 20. In this example, the shoji 4 has glass 43 held on the inside by glazing channel beads in the glass grooves on the inner peripheral side of each stile, and a surface lattice 44 is held on each stile on the outside of the glass 43. FIG. 4 is a drawing showing details of the joining part. A gasket 34 having a tongue-shaped piece protruding outward from the shoji 4, 4 is fitted into the groove 32 of the matching frame 21, 21', and when the shoji 4, 4 is closed, the tongue-like portion of the gasket 34, 34 is inserted. The pieces are adapted to come into contact with each other, and the upper ends of the packings 34, 34 are arranged to contact or come close to the fins of a packing 25 fixed to the upper frame 2 shown in FIG.
An L-shaped blinding material 47 is provided at the left end of the inside of the joining stile 21' so as to cover the right end of the joining stile 21, and the blinding material 47 is provided with a groove 48 facing the outside. A gasket 49 is fitted into the shoji 4, and the tongue-shaped portion of the gasket 49 comes into contact with the right end of the inner side surface of the stile 21 of the shoji 4, and the upper end of the gasket 49 is attached to the upper frame 2 in FIG. The lower end portion contacts or approaches the lower part of the packing 22 fixed to the lower frame 3, and the lower end portion contacts or approaches the upper part of the packing 22 fixed to the lower frame 3.

When the shoji 4, 4 are closed, a vertically long open space 50 at both ends is formed, surrounded by the matching frames 21, 21' and the packings 34, 49, as if a double-sided shoji had inner and outer materials, respectively. It becomes like a single piece of shoji.

When wind and rain blows with the shoji 4, 4 closed, the gasket 25 restricts its entry between the upper frame 2 and the upper stile 18, and the gasket 34 prevents it from entering between the vertical frame 1 and the vertical stile 20. Ru.

Wind pressure caused by wind and rain causes a labyrinth effect when it passes between the end of the outer member 38 of the lower stile 19, the water gradient member 15, the water return 14, and the inverted L-shaped protrusion 41 and enters the space 42. Therefore, the wind pressure caused by sudden blowing is reduced before being transmitted to the spaces 37, 28 between the opening frame and the shoji, and is transmitted from both sides of the space 42 to the spaces 37, 28. Air is blown from between the lower frames 19, 19 and the lower frame 3, but from the lower side of the space 50 for the above-mentioned casement window,
There is pressure propagation due to communication to the upper side and to the space 28 between the upper frame 2 and the upper frames 18, 18.
Therefore, if the static pressure on the outside side is Po and the static pressure inside the room is Pi, the pressure increase due to wind and rain blows into the space 42,
37 and 28 exhibit a pressure Pr intermediate between the static pressures Po and Pi. Therefore, even if there is a defective part in the inner packings 22, 49, the pressure Pr applied between the packings 22, 49 and the frame of the shoji 4 is small, and rainwater will not seep in. When the shoji 4 is opened toward the outside around the hinge 36, the packing 22 is separated from the frame of the shoji 4. At that time, there are no water droplets attached to the gaskets 22 of the upper frame 2 and vertical frame 1 due to the rainwater being blown in, so
There will be no dripping, and you won't have to stick your neck out the window and have water droplets fall on your neck. Even when wind and rain are blowing in extremely strongly, the wind and rain that blow in from between the lower stile 19 and the lower frame 3 of the shoji are decelerated and decompressed, so the rainwater flows to the lower part of the gasket 22 attached to the vertical frame 1 and the gasket 49 of the connecting stile. Even if you get it wet, the upper part remains dry.

[Effects of the invention] As explained above, the invention is to surround the window frame with a gasket that contacts the inside surface of the stile of the shoji in a window that opens on both sides. A gasket is provided on the connecting stile to seal the space between the connecting frames, and a gasket is provided between the upper stile of the shoji, the vertical stile and the upper frame of the window frame, and the vertical frame at a position on the outside side of the connecting stile, and the outside of the connecting stile is provided. On the side, there is a gasket that seals the space between the stile frames, and the outside of the shoji is hung down to form a labyrinth so that it overlaps with the water return member of the lower frame, so it surrounds the window frame and the sill frame. The padskin placed on the inside of the stile and the padskin installed on the inside of the stile that closes the stile are less likely to get wet with rainwater, and even if there is some defect in the sill, rainwater from outside will not leak out. does not seep into the interior. Therefore, when the window is opened, water will not drip down inside the window frame or shoji frame.
