This invention relates to a device for preventing the outer shoji from falling off, which has an airtight structure for maintaining the airtightness of the outer shoji built into the sash frame.

[Conventional technology]

Japanese Utility Model Application Publication No. 1987-19274, which discloses a technology for a shoji shoji removal prevention device, states that the lifting gap for an outer shoji is calculated from the distance between the upper end of the outer rail and the lower edge of the outer plate of the lower end rail groove of the outer shoji. The distance between the lower edge of the inner plate of the lower end rail groove of the outer shoji and the upper end of the outer rail, and the interval between the lower edge of the lower end rail groove of the inner shoji and the upper end of the inner rail, are made smaller than the above-mentioned lifting interval. It also describes a sliding window technology that prevents the outer shoji from falling off to the outside by forming the lower edges of both shoji on the same horizontal plane, making it possible to erect and remove the outer shoji from the indoor side. There is. On the other hand, in Japanese Utility Model Publication No. 51-24776, which disclosed a technology for a sealing device for shoji shoji, an airtight material is attached to the indoor side walls of the lower stile of the inner and outer shoji, respectively, and the airtight material of the inner shoji is Touching the rising wall of the frame,
A window technique is described in which the airtight material of the outer shoji is brought into contact with the rising portion of an auxiliary member provided between the inner and outer rails to prevent rainwater from entering the room.

[Problem that the idea aims to solve]

However, the former of this prior art
The structure is simply for preventing the shoji from coming off and for installing and removing it from the indoor side, and it cannot be said that maintaining the airtightness of the outside shoji is sufficient for practical purposes. Although the latter type of shoji can achieve airtightness, it is extremely dangerous because there is a risk of it coming off to the outside when the shoji is installed or removed. Therefore, this invention has been developed in view of the problems of the prior art described above, and it is possible to erect and remove the outside shoji from the indoor side without the outside shoji coming off unnecessarily to the outside. The purpose is to obtain a device with a simple structure by using a vertical cell that can maintain its properties.

[Means to solve the problem]

As a means to achieve this, this invention has a sliding sash in which an inner shoji and an outer shoji are slidably built into a sash frame, and the overlapping dimension of the inner side wall of the lower stile of the outer sash and the outer rail is It is formed larger than the lifting dimension of the shoji, and an airtight rising part is formed between the inner side wall of the lower stile of the outer shoji and the inner and outer rails on the side of the lower sash frame, and the rising part of the inner side of the lower stile of the outer shoji, the above rising part and the inner rail are formed. The overlapping dimension is made smaller than the above-mentioned lifting dimension, and a tight material is provided on one side between the indoor side wall and outdoor side wall of the lower stile of the outer shoji and the above-mentioned rising part and outside rail, and the other side is made airtight. The lower stile of the outer shoji is formed into a space that is airtightly isolated from the indoor side, and the space is communicated with the outdoor side through an air hole provided in the lower frame of the sash. .

It is assembled by fitting a panel 22 into the frame 20 and door stop side vertical frame 21. Furthermore, the inner rail 7 of the lower frame 3 is
The bottom wall 3b is erected at the tip of the bottom wall 3b which projects horizontally from the base end of the rising wall 27 erected at the indoor end toward the outdoor side, and the outer rail 8 projects diagonally downward from the indoor end toward the outdoor side. Further, it is erected near the outdoor end of the horizontally bent lower frame base wall 3a so as to protrude upward from the inner rail 7. A groove-shaped space chamber 30 is formed on the lower frame base wall 3a between the outer rail 8 and the indoor end.
At the same time, a drain/air hole 31 communicating with the outdoors is provided at the lower end of the outer rail 8. Reference numeral 23 denotes an auxiliary lower frame, which is engaged and fitted between the outdoor side of the base end of the inner rail 7 and the opposing outer rail 8 and the indoor side;
In addition, its length is set to a length dimension where the mating side vertical stile 20 of the outer shoji 17 is located from the left vertical frame 4 when the outer shoji 17 is closed and tightly attached to the left vertical frame 4,
In addition, the auxiliary lower frame 23 has the inside wall 19 of the frame room of the outer shoji 17.
A rising portion 24 facing the indoor surface of a is provided upright.
On the other hand, a tight member 25 that contacts the rising portion 24 is attached to the indoor surface of the inner wall 19a of the frame chamber of the outer shoji 17, and a draining tight member 35 that contacts the outer rail 8 is attached to the outer wall 19b of the frame chamber, and both tight members There is a space 2 in the lower stile 19 surrounded by 25 and 35.

The relationship between the above-mentioned inner and outer shoji 11 and 17 and the inner and outer rails 7 and 8 is as follows: a: Lifting dimensions of the inner and outer shoji 11 and 17, b: Frame room outer wall 19b of the outer shoji 17 and the outer rail 8
Overlap dimension c: Inner wall 19a of the stile room of the outer shoji 17 and the outer rail 8
Overlap dimension d: Overlap dimension between the lower stile 12 of the inner shoji 11 and the inner rail 7 e: Projection height dimension from the upper end of the inner rail 7 to the upper end of the outer rail 8 f: The stile interior side wall 19a of the outer shoji 17 and inner rail 7
The overlapping dimensions with these relationships are c>a>b a>d c>e+d e>c−a f<a. Since it is configured like this, the outer shoji 1
Even if you try to remove the shoji 7 by lifting it upwards, the overlapping dimension c between the inner side wall 19a of the outer shoji 17 and the outer rail 8 is larger than the lifting dimension a, so it will definitely not be possible to remove it to the outside. Therefore, when removing the outer shoji 17, after removing the inner shoji 11 to the indoor side, lift the outer shoji 17, move the stile room outer wall 19b above the outer rail 8, and move the stile room inner wall 19a to the auxiliary lower frame 2. The outer shoji 17 can be removed from the indoor side by lifting it upward from the rising portion 24 and pulling it out in the direction of arrow A. Moreover, when installing the outer shoji 17, it is sufficient to perform the operation opposite to the above-mentioned removal operation. Furthermore, when the inner and outer shoji 11 and 17 are erected and the shoji is in the closed state, the inner side wall 19 of the outer shoji 17
The tight material 25 of a is in airtight contact with the rising portion 24 to form a space 26, and the tight material 28 of the stile room inner wall 13a of the inner shoji 11 is also in airtight contact with the rising wall 27. The spaces 26 and 29 are communicated with a space chamber 30 through air holes 32 and 32a, and the space chamber 30 has a drain/air hole 31 and an inner shoji 11 without the auxiliary lower frame 23.
Since the outdoor side of the shoji 11, 17 directly communicates with the outside air, both the spaces 26, 29 are maintained at approximately the same pressure as the outside air pressure.
There is no pressure difference between the external pressure from 9b and the rainwater that has entered the space 26 flows through the air hole 32 into the space chamber 3.
The rainwater that has entered the outdoor space 29 through the air hole 32a flows through the air hole 32a into the space chamber 30 on the lower frame base wall 3a.
The tight material 25,
Intrusion of rainwater from the contact portion 28 into the indoor side is reliably prevented. FIG. 3 shows another embodiment of this invention, in which the rising portion 24 of the auxiliary lower frame 23 is
protrudes at the same height as the upper end of the inner rail 7,
The inner shoji 11 connects the lower end of the inner side wall 19a of the outer shoji 17 which is in airtight contact with this through the tight material 25.
It is constructed so as to be located above the lower end of the outer side wall 13b of the frame chamber. With this structure, the overlapping dimension f between the inner side wall 19a of the outer shoji 17 and the inner rail 7 is smaller than that of the above embodiment, so that the outer shoji 17 can be removed or built on the indoor side. This makes it even easier to incorporate. Note that the auxiliary lower frame 23 provided with the rising portion 24 may be attached over the entire length of the lower frame 3. Further, instead of the auxiliary lower frame 23, it may be formed integrally with the lower frame 3.

[Effect of the idea]

As described above in detail with respect to the embodiments, in this invention, even if the outer shoji is lifted, the inner wall of the stile interior does not protrude above the outer rail, so it is possible to reliably prevent the outer shoji from coming off to the outside. . At the same time, tight materials provided between the indoor side wall and outdoor side wall of the lower stile of this outer shoji and the above-mentioned rising part and outer rail are brought into airtight contact with each other, so that the inside of the lower stile of the outer shoji is airtight with the indoor side. It is formed in a space that is isolated from the outside and communicates with the outdoors through the air hole on the side of the sash bottom frame, so it maintains airtightness with the inside of the room and reliably prevents rainwater from entering. As a result, it is possible to obtain a shoji slip-off prevention device having a simple structure and a rigid airtight retaining structure.
