Description

[Detailed description of the invention] Industrial field of application In the present application, the outdoor shoji (hereinafter referred to as outer shoji) is fitted, and the indoor shoji (hereinafter referred to as inner shoji) is opened and closed. This relates to maintaining the airtightness of a so-called internally moving single-pull sash.

Conventional technology Conventionally used single sliding sashes are often of the external movement type, in which the inner sash is inserted and the outer sash opens and closes, as it is relatively easy to maintain airtightness when closing and pulling. .

However, in recent years, the above-mentioned external sliding type has disadvantages such as the fact that the outer shoji can only be installed and removed from the outside, and in the event of a wheel derailment, the outer shoji will fall to the ground. As this becomes a bigger problem as buildings become taller, there is a demand for an internally moving type in which the inner shoji opens and closes while the outer shoji is inserted. Conventionally, this type of soundproof satsushi was used in 1983.
The one shown in Japanese Patent No. 49335 is known, and in order to meet the above-mentioned requirement for the internal motion type, the present applicant also developed the
No. 41494 "Movable airtight sash"
An application has been filed for an internal motion type single pull satsushi.

Problems to be solved by the invention In the conventional internally moving single-pull sash mentioned above, the seal is made on the outside of the room from the shoji guide rail.
There is a rising part for installing the airtight material, which makes drainage extremely inconvenient, rainwater easily enters due to the difference between external and internal pressure, and the airtight material is exposed to sunlight and wind. It has disadvantages such as aging easily.

Means for Solving the Problems In view of the drawbacks of the conventional device described above, the present application maintains the airtightness of the lower stile between the shoji guide rail provided on the lower frame and the indoor side piece of the lower stile, and By forming the outdoor side part of the lower stile lower than the shoji guide rail of the lower frame so that the lower end of the lower stile opens to the outside (atmosphere) when the shoji is closed,
The present invention will be described in detail below with reference to drawings showing embodiments of the present invention, which eliminates the drawbacks of the conventional single-drawn sash mentioned above.

Example In Fig. 5, 1 is a window frame, a lower frame 2, an upper frame 3,
It is composed of both left and right vertical frames 4, 5 and a mullion 17. As is clear from FIGS. 1 and 2, the lower frame 2 in this embodiment includes a base plate 7 with a shoji guide rail 6 protruding from the edge on the outdoor side, and a bottom plate 8 hanging down from the base plate 7. , by a mounting frame 9 attached to the substrate 8 so as to be placed on the top of the bottom plate 8 over approximately half of the total length of the substrate 7, that is, between the mullion 17 and the vertical frame 4 in FIG. It is configured. As is clear from the above, the lower frame 2 of the opening portion 10 between the mullion 17 and the vertical frame 5 has a large step between the shoji guide rail 6 and the bottom plate 8, and is open to the outside of the room.

11 is an outer shoji located between the mullion 17 and the vertical frame 4 and erected between the above-mentioned mounting frame 9 and the upper frame 3, and the outer shoji 11 is completely fitted. Next, 12 is an inner shoji screen installed on the indoor side of the window frame 1, which can be opened and closed freely.
Upper stile 13, lower stile 14, combined stile 15, and doorstep stile 1
6. Therefore, the inner shoji 12
In the closed position shown in FIG. 2 (same as the opening part described above), since the lower frame 2 is configured as described above, the lower frame 14 extends from the lower end 14a of the lower stile 14 to the interior space 14d, and the outdoor side is open to the atmosphere (Figure 1). In addition, by operating the handle 18 in the closed position, the pulling mechanism 19 built into the stile 15 is activated, pulling the stile 15 toward the outdoor side and pulling both upper and lower ends of the stile 15 and the upper frame. 3 and the lower frame 2 is conventionally closed, but since this drawing mechanism is appropriately selected from conventionally used mechanisms, the details thereof will be omitted. Further, in this embodiment, the door frame 16 is pulled in using a handle 20 attached to the door frame 16, but this pulling can be done using a conventional method such as using a pulling block. It is adopted as appropriate from
The structure does not matter as long as it draws the air to the outside of the room.

As described above, in the present application, each part is kept airtight as described in detail below. First, the airtightness of the lower stile 14, which is an important part of the present invention, is maintained as follows. In FIGS. 1 and 2, 21 is
It is an airtight material fitting piece provided on the base plate 7 of the lower frame 2, and is located between the indoor side surface 6a of the shoji guide rail 6 and the indoor side piece 14b of the lower stile 14 of the inner shoji 12 in the closed position. . The airtight material 22 is attached to the airtight material fitting piece 21 so that the sealing surface faces the indoor side. Therefore, when the inner shoji 12 is closed, the indoor side piece 14b of the lower stile 14 and the airtight material 22 are separated. As shown in Figure 1, they face each other with a small distance between them. Furthermore, lower frame 2
A drain hole 23 is bored in the base plate 7 between the shoji guide rail 6 and the airtight material fitting piece 21 in correspondence with the lower stile 14 in the closed position (FIG. 4).

Next, the upper stile 13, the door stile 16, and the closing stile 15.
Airtightness is maintained as follows. In FIG. 1, 29 is an airtight material fitting piece that hangs down from the upper frame 3 to the outdoor side of the indoor side piece 13a of the upper stile 13.
In FIG. 2, reference numeral 24 is an airtight material fitting piece that is provided on the vertical frame 5 and corresponds to the indoor side piece 16a of the door frame 16 on the outdoor side. The airtight members 25 and 26 are attached so as to face inward, and these airtight members 25 and 26 and the above-mentioned airtight member 22 for the lower stile 14 form a substantially coplanar sealing surface. Next, reference numeral 27 denotes an airtight material fitting piece provided on the mullion 17, and an airtight material 28 is also attached to the fitting piece 27 with the sealing surface facing toward the indoor side. As described above, when the inner shoji 12 is closed, the upper stile 13, the door stile 16, and the door stile 15 are airtight, as is the case with the lower stile 14, as is clear from FIGS. 1 and 2. It faces the materials 25, 26, and 27 with a slight distance between them.

Close the inner shoji 12, then close the handle 18,1
By performing the operation 9, the inner shoji 12 is pulled toward the outside of the room as described above, and the lower stile 14 and the upper stile 1
3 and the indoor side pieces 14b, 13a, 1 of the door frame 16
6a and the connecting frame 15 are made of airtight materials 22, 25, respectively.
26 and 27, and the upper and lower ends of the stile 15 and the space between the upper and lower frames 3 and 2 are simultaneously closed, so that the entire four circumferential surfaces of the inner shoji 12 are kept completely airtight.

Therefore, the lower frame 2 in the present application is constructed as described above, and is open to the atmosphere without providing a rising portion on the outdoor side of the lower stile 14.
The outdoor side piece 14c protrudes outward from the base plate 7 to a large extent and faces the bottom plate 8.
The rainwater that hits the bottom stile 2 flows down the bottom plate 8 through the lower stile 14, and even if the wind and rain become strong, the rain will be blocked by the shoji guide rail 6, and the space 1 at the bottom of the lower stile 14 will flow down.
4d has the same pressure as the atmosphere, so it is difficult to blow onto the substrate 7, and even if it does, it will flow down from the drain hole 23 onto the bottom plate 8, preventing rainwater from entering the indoor side from the sealing surface. The lower frame 2 can be washed and cleaned very easily.

Next, the present application can also be implemented by the following modified examples. In the above, the airtight material 22 for sealing the lower stile 14 is attached to the airtight material fitting piece 21 provided on the board 7, but it may also be attached directly to the shoji guide rail 6, or the lower stile 14, indoor side The airtight material 22 may be attached to the outdoor side of the piece 14b, and the airtight material 22 may be pressed against the corresponding plate directly on the shoji guide rail 6 or by replacing the airtight material fitting piece 21 with a flat backing plate. Shoji guide rail 6 and indoor side piece 14 of lower stile 14
If the lower stile 14 is sealed between the lower stile 14 and the lower stile 14, the object of the present invention can be achieved. Needless to say, bottom frame 1
Upper stile 13, door stile 16 and side stile 15 excluding 4
The mounting positions of the airtight members 25, 26, and 27 that perform the sealing are not limited to those mentioned above, and can be changed as appropriate as long as they can seal the three frame materials.

Effects of the invention As described above, in the present invention, the outdoor side part of the shoji guide rail in the lower frame is lower than the lower end of the indoor side shoji on the outdoor side, and the indoor side of the shoji guide rail and the lower stile of the indoor shoji Since the space between the shoji guide rail and the indoor side piece is sealed with an airtight material, it is possible to eliminate the need for a rising piece for attaching the airtight material from the indoor side of the shoji guide rail, and as a result, the space between the shoji guide rail and the outdoor side can be omitted. In this case, rainwater falling on the lower frame can be easily drained to the outdoor side, and garbage accumulated in this part can be easily swept out to the outdoor side. In addition, the lower end of the outdoor side of the lower stile of the indoor shoji is allowed to hang down at a distance from the outdoor side of the shoji guide rail, so rainwater that sprays against the outdoor side of the lower stile falls from the shoji guide rail to the outdoor side, creating an airtight seal. It is possible to prevent rainwater from directly hitting the material, thereby preventing rainwater from entering the room from the sealed part of the airtight material due to the pressure difference between indoors and outdoors, improving the watertightness of this type of sash. Further, since the airtight material is provided on the indoor side of the shoji guide rail, the airtight material can be prevented from being exposed to sunlight, wind and rain, and the life of the airtight material can be extended.
