Description

[Detailed Description of the Invention] The present invention relates to an airtight device for a sash in which a sash door is double-shielded from the lower frame step wall and the shoji rail step with a tight material.

Conventionally, the mechanism for making the shoji door and sash bottom frame airtight was as follows:
A structure in which a tight material is attached to either the inside of the lower stile of the shoji door or the vertical side wall of the sash bottom frame, and its tip is pressed against the other, or either the outside of the shoji door's lower stile and the lower end of the sash rail. There are some that have an airtight structure by attaching tight material to the.

In this way, with conventional devices, each shoji door has only one airtight part, so it is not possible to sufficiently prevent wind and rain from entering during strong winds and rain, and there are also errors in the dimensions of the sash bottom frame and the installation of the shoji door. For example, due to the fact that the distance between the rail and the vertical wall surface is not constant over the entire length, the pressing condition between the tight material and the contact surface fluctuates, making it impossible to maintain a constant airtightness. had.

In addition, conventional sash bottom frames have the disadvantage that the airtightness is particularly reduced at the side ends of the shoji rails because the side ends of the shoji rails are cut out to form a cutout in order to remove dust. .

Therefore, in this invention, each shoji door has a double airtight part, so that even in strong winds and rain, and even if there is a dimensional error in the sash bottom frame or shoji door, the shoji and sash bottom frame can be easily fixed. In addition, even if the shoji rail is partially cut out, the other airtight part maintains the specified airtightness to prevent the occurrence of non-airtight areas. This paper proposes an airtight device for sashes.

The present invention will be described below based on embodiments shown in the drawings.

Fig. 1 is a vertical sectional side view showing the state of use of the present invention.
and the second step section 2, 2 are arranged side by side, and the screen door step section 3 and the rain door step section 4 are provided in front so as to be attached externally, and a hollow section for reinforcement is provided on the back side of the front half part. It is constructed by taking the form of 5.

Each of the first and second step surfaces 2, 2 is provided with shoji rails 6, 6 so as to be located above the window sill A of the building at the center of the coast.
is laid, and on the outer side of this rail 6, each stepped surface part 2, 2 is further made into a stepped shape, and a vertical surface is formed on the same vertical plane as the outer surface of the rail 6, which stands almost perpendicularly to the middle part of the stepped surface part. Wall 7 is designed to be a formal precept.

The above-mentioned lower frame 1 is framed with a normal vertical frame 8 as shown in FIG.

Further, as shown in FIG. 3, the side end portion of the shoji rail 6 provided on the lower frame 1 may be formed with a cut-out portion 16 for removing dust by known means.

Vertical side walls 9, 10 are provided at the inner part of each of the first and second stepped surface portions 2, 2 over the entire length thereof.

That is, the outer shoji door 1, which will be described later, is formed between the stepped portions 2 and 2.
A vertical side wall 10 is provided at a position facing 1, and a vertical side wall 9 facing an inner shoji door 11 is provided inside the first step section 2.

A shoji door 11.11 is slidably mounted on the shoji rails 6, 6 of the lower frame 1.

On the inner side of the outer side of the lower stile room of each shoji door 11, receiving grooves 12 that protrude inward through rib pieces are formed alternately across the entire width, and the grooves 12 are filled with tight material. 13 is fitted toward the indoor side, and its tip is brought into sliding contact with the vertical wall 7 that is flush with the outer surface of the shoji rail 6.

A receiving groove 14 is formed on the outer surface of the inner side of the lower frame of the shoji door 11, and a tight material 15 is fitted into the groove 14 toward the indoor side, and its tip is attached to each vertical side wall 9. , 10 are in sliding contact.

In this way, each shoji door 11.11 has a structure in which the vertical wall 7 and the vertical side walls 9, 10 have double airtight portions.

The hollow portion 5 described above is configured to have a hollow cylindrical shape, and the shoji rail 6 of the second stepped surface portion 2 which is the outer portion
It is placed on the back side of the building so that it is attached externally to the window sill A of the building.

That is, the base end 5a of the hollow part 5 is brought into contact with the window sill A,
A flange 19 extending downward from the portion 5a is fixed to the window sill A with nails 20.

17 is a screen door rail, and 18 is a shutter.

Tight material 13 installed inside the lower stile of the shoji door 11 mentioned above
Although it partially contacts the outer surface of the shoji rail 6, it mainly slides into vertical wall 7 as shown in FIG. 1, and for example, as shown in FIG. When the portion is cut off, the tight material 13 comes into sliding contact only with the vertical wall 7, as shown in FIG.

As described above, this invention has a structure in which each of the inner and outer shoji doors has a double airtight part for the vertical wall and vertical side wall of the lower frame, so that even in strong winds and rain, the sash lower frame Even if there is an error in the dimensions of the shoji door or shoji door, it can provide sufficient shielding from wind, rain, dust, etc.

Moreover, even if the side ends of the shoji rail are removed during use,
The cutout part is still shielded from the outdoors because the tight material is in partial sliding contact with the lower vertical wall, and the other tight material is in secure sliding contact with the vertical side wall.
Deterioration of the airtight effect can be prevented.
