Description

[Detailed Description of the Invention] The present invention relates to an airtight device for windows.

In conventional sashes, an airtight material is attached to the shoji stile or window frame to maintain airtightness between the shoji frame and the window frame.

Therefore, it is necessary to provide a locking part on the shoji stile or window frame for attaching the airtight material, which poses various design problems and high costs.

Furthermore, the shoji requires a separate glazing gasket made of synthetic rubber or synthetic resin for attaching the glass plate.

In view of the above points, this invention was developed as a result of various studies to maintain airtightness by omitting the locking part for attaching the airtight material.
It was discovered that good results could be obtained by integrally molding the glazing gasket and the airtight material, and the present invention was proposed.

The structure of the present invention will be explained in detail based on the first embodiment shown in FIGS. ,2
(see figure) is retained in water honey.

This glazing gasket 4 has an arc-shaped airtight piece 5 integrally formed at the bottom on the indoor side and along the stile 2.

As shown in FIG. 3, the glazing gasket 4 is attached so as to go around the shoji from the center of the upper stile through one short root to the lower stile, and then to the other short root and the center of the upper stile so as to go around the shoji without a break.

In addition, there is a 5th plate at the abutting part of the 6-matching frames 6, 6 of both shoji 1, 1.
As shown in the figure, the airtight block 7.7 is fitted except for the upper and lower ends.

The airtight block 7.7 has fitting grooves 8, 8 on both sides, respectively, and is fitted and fixed in retaining pieces 9, 9 protruding from both ends of the six-piece frame 6.

The joint surfaces 10 of the airtight blocks 7.7 are i-shaped and are attached symmetrically to each other, with the protrusions 11 abutting against the flat surfaces 12.

Also, upper and lower end airtight blocks 13 are provided at the upper and lower ends of the six mating frames 6, 6, as shown in FIGS. 3 and 4. ... are installed respectively.

Upper and lower end airtight blocks 13. . . . has fitting grooves 14 and 1 on both sides, as shown in FIG.
4 and the joint surface 15? An airtight connecting piece 16 is provided horizontally on one end of the interior of the room to connect the airtight piece 5 and the end face of the airtight block 7.

The free end of this airtight connection piece 16 is provided with an arcuate abutting surface 17 with a thinner wall so that it can easily come into contact with the airtight piece 5.

On the other hand, the window frame 18 is constructed in the form of a hidden frame as shown in FIGS. 1 and 2.

That is, as shown in FIG. 2, the upper frame 19 extends upward from the outdoor end of the indoor upper surface 21 that is in contact with the upper surface of the window opening 20, and extends the upper vertical pieces 22 on both sides of the window opening 2o by the width of one shoji screen. A connecting top plate 23 is provided horizontally from the upper end of this upper vertical piece 22, an outer wall 24 is provided on the connecting top plate 23 in parallel with the upper vertical piece 22, and a guide protrusion is provided on the lower center surface of the connecting top plate 23. Article 25 has been established.

In addition, as shown in FIG. 2, the lower frame 26 has a lower vertical piece 28 extending downward from the outdoor end of the indoor lower surface 27 that contacts the lower surface of the window opening 20, and a shoji screen on both sides of the window closing portion 2o. A draining plate portion 29 is provided which is inclined from the lower end of the lower vertical piece 28, and the outdoor terminal surface of the draining plate portion 29 has an h
A shaped lower outer wall 3o is provided, and a rail 31 is provided protruding from the upper center surface of the draining plate portion 29.

In addition, the window opening side frames 32 and 32' are as shown in FIG.
An indoor side surface 33 and an outdoor side surface 34 of the window opening 20 which are in contact with the indoor and outdoor sides are shaped into a single cross section, and this is connected to the upper and lower frames 19°26.

Further, the outer ends of the upper and lower frames 19.26 are connected by side frames 35.35' as shown in FIG.

The shoji 1.1 is inserted into the window frame 18 constructed as described above so that it can be opened and closed.

The first embodiment of the present invention is constructed as described above, and since the window frame 18 is a hidden frame, only the glass plate 3 of the shoji 1.1 is visible from the inside.

When both pupils 1, 1 are closed, the airtight piece 5 comes into contact with the periphery of the window opening 20 of the window frame 18 on the outdoor side to maintain airtightness, as shown in FIG. 1.2.

The abutting portions of the connecting frames 6, 6 of both pupils 1, 1 are kept airtight by abutment with both airtight blocks 7.7, and airtight connection pieces 16 are also provided on the upper and lower sides of the indoor side of the connecting frames 6, 6. .16
Since it comes into contact with the airtight pieces 5, 5 of both pupils 1, 1 to maintain airtightness, it also prevents outside air and rainwater from entering from above and below the connecting frame 6.6.

Next, the second embodiment will be explained based on the drawings shown in FIG. 7 and below. Unlike the first embodiment, the airtight connection piece 16' is formed separately, and a coupling protrusion 36 is provided protruding from the center of the outdoor side. Fitting grooves 37, 37 are provided on both sides of this coupling projection 36, and an abutment surface 17 is provided at one end on the indoor side as in the first embodiment.

On the other hand, the joining frames 6', 6' of the shoji 1, 1 are respectively constructed in a shape in which a connecting groove 39 in the form of a groove with a lip is provided on the interior surface 38, as shown in FIG.

The coupling protrusion 3 is attached to the lip 40.40 of the coupling groove 39.
The airtight connecting pieces 16' are fixed to the mating frames 6', 6' by fitting the fitting grooves 37, 37 of No. 6 into place.

Incidentally, the airtight block 7 may be provided up to the upper and lower ends of the connecting frame 6'.

Everything else is the same as the first embodiment, so the explanation will be omitted.

The second embodiment is constructed as described above, and since the upper and lower airtight blocks of the first embodiment are not present, the whole has the same shape as shown in FIG. , 6' have airtight connecting pieces 16', 16' at their upper and lower ends, respectively.
, it is possible to maintain sufficient airtightness.

The present invention is constructed as in the embodiment described above, and the window opening 20 is reliably sealed by the airtight piece 5, the airtight block 7.7, and the airtight connection piece, so that there is no risk of outside air or rainwater entering.

Further, since the airtight piece 5 is provided integrally with the glazing gasket 4, the installation is completed by attaching the glass plate.

Therefore, no special work or locking member is required for attaching the airtight piece, which is very convenient.
