0, 40, and 56, and at the same time, the indoor side stile board 29 of the outer shoji stile 16 is pressed together with the shim packing 66, the packing 45, and the frame packing 30.
40 is continuously crimped. On the other hand, when the upper closing member 67 is lifted up by the rotation of the crescent 18 in the locking direction, the upper surface of the closing packing 67b of the closing member 67 is exposed to the top plate 20 of the upper frame, as shown in FIG. It is crimped to the groove-filling piece 101 and the outer shoji frame packing 30, and also substantially contacts both sides of the inner shoji guide piece 22, and the indoor side surface of the closing packing 67b is attached to the indoor side stile plate 27 of the inner shoji joining stile 10.
It is crimped to the inner shoji frame packing 28 of the upper frame 2 in a state that is substantially continuous with the abutment surface 27a of the closing packing 67b. The space between the upper end of the inner shoji sash 10 and the sash packing 66 and the upper frame 2 is made airtight (in this application, even a slight gap is considered airtight). (including) is occluded. Also,
When the lower closing member 68 is lowered, the lower surface of the closing packing 68b of the closing member 68 is pressed against the base plate 31 of the lower frame 3 and the airtight piece 42 and comes into contact with both sides of the inner shoji guide rail 35 in the same manner as described above. death,
The indoor side surface of the closing packing 68b is crimped to the inner shoji frame packing 39 of the lower frame 3, and the outdoor side surface of the closing packing 68b is crimped to the indoor side stile plate 29 of the outer shoji fitting stile 16. Frame 1
The gaps between the lower ends of the packing 66 and the lower frame 3 and the airtight piece 42 are hermetically closed. As described above, the spaces between the inner and outer shoji 6 and 12 and between the inner and outer shoji 6 and 12 and the window frame 1 are reliably closed.
When the inner and outer shoji 6 and 12 are closed as described above, the spaces between the inner and outer shoji 6 and 12 and between the inner and outer shoji 6 and 12 and the window frame 1 are actively closed.
The watertightness and soundproofing performance of this sliding soundproof sash can be made extremely high. In addition, since a space with a large height dimension is formed between the lower stile 14 of the outer shoji 12 and the water storage step 41 of the lower frame 3, even if rainwater enters the indoor side of the outer shoji 12 for some reason, This rainwater accumulates in the space, and the pressure on the indoor side of the frame packing 40 can be balanced with the pressure on the outdoor side, thereby preventing an accident of rainwater overflowing into the room.

Next, when opening the inner and outer shoji 6, 12, the crescent 18 is rotated in the unlocking direction. As a result, the closing members 67, 68 are returned to their original positions as shown in FIG. 9, the drawing movement of the inner and outer shoji 6, 12 is released, and the inner and outer shoji 6, 12 become openable and closable. In this state, the inner and outer shoji can be completely slid apart from each other. In this case, the groove filling piece 101 is fitted into the mounting groove 100 and the top plate 2
0Protruding objects below the bottom surface (e.g. fixing screws, etc.)
Since there is no interference between the closing member 67 and the groove filling piece 101 when the inner shoji 6 is opened and closed, it is possible to prevent the closing member 67 from interfering with the groove filling piece 101. In addition, when you want to remove the inner and outer shoji 6, 12, you can move the inner and outer shoji 6 in and out from the indoor side first.
can be removed and installed easily and safely.

In this case, since the airtight piece 42 is attached to the lower frame 3, the inner shoji 6 can be closed by slightly raising the closing member 68 provided on the stile 10 of the inner shoji 6.
This has the advantage that the closing member 68 can be moved up and down stably. In the drawing, the closing member 68 is raised to a position where its lower end is considerably higher than the lower end of the connecting frame 10, but the closing member 68 is raised to a position where its lower end is at the same height as the lower end of the connecting frame 10. It is enough to raise it.

Next, in the case of the above structure, a mounting groove 100 is formed in the top plate 20 of the upper frame 2 in the same manner as the upper frame of a normal sash, and a mounting groove 100 is formed in the base plate 31 of the lower frame 3 in the same way as in the lower frame of a normal sash. A stepped portion 41 for water storage is formed, and the upper stile 7, 13 and the lower stile 8 of the inner and outer shoji 6, 12,
14 has packing mounting grooves 46a and 47 to which fin-like packing can be attached, similar to the upper stile of a normal sash.
Since a is formed respectively, the upper frame 2 and lower frame 3 are used as the upper frame and lower frame of ordinary ordinary sashes (general residential sashes that do not have an airtight structure like soundproof sashes) in the sash production line. Of course, it is possible to
and lower stile 8, 14 are also packing mounting grooves 46a, 47
By attaching fin-like packing to a, it can be used as the upper frame and lower frame of ordinary sash, and as a result, in the manufacturing process, the upper frame 2, lower frame 3, upper frames 7, 13, and lower frames 8, 14 can be used as the upper frame and lower frame of ordinary sash. It can be manufactured on the same line as other products, improving mass production.

Effects of the invention As described above, in the present invention, the inner shoji guide rail is formed at a height that is approximately the same as the height of the rain flap, and there is a large stepped water pool on the outdoor side of the inner shoji guide rail. An airtight piece for water storage is provided at the meeting part of the upper surface of the lower frame between the step and the inner shoji guide rail, so when the shoji is closed and drawn,
A deep water reservoir recess can be formed between the outer shoji lower stile and the water reservoir step, and as a result, water that has entered the indoor side of the outer shoji can be collected in the water reservoir recess and balanced with the external pressure, making it possible to prevent indoor water leakage during rainstorms. It can reliably prevent rainwater from entering. In addition, attach the outer shoji frame packing to the step part of the lower frame so that the upper surface continues to the upper surface of the lower frame.
The inner shoji frame packing is attached to the rain return piece so that the lower surface is continuous with the upper surface of the lower frame, and the airtight piece is provided with packing that is substantially flush with the outdoor side of the outer shoji frame packing so as to cover the entire upper and lower width, Since the closing member that closes the space of the connecting part of the inner shoji connecting stile is installed so that it can be raised and lowered, when the closing member is lowered,
With the closing member, the space surrounded by the inner shoji frame, the inner shoji frame packing, the upper surface of the lower frame, the airtight piece, the packing, and the outer shoji frame can be reliably closed with high airtightness and watertightness. , the soundproofing performance of soundproofing satsushi can be improved. In addition, the height of the inner shoji guide rail is made high so that it is almost the same as the height of the rain return piece, and the upper surface of the lower frame between the inner shoji guide rail and the rain return piece is also formed high, so that the height of the airtight piece is increased. The upper surface of the lower frame between the inner shoji guide rail and the rain return piece is made to be approximately the same as the upper surface of the lower frame, and the closing member is in pressure contact with the upper surface of the airtight piece and the upper surface of the lower frame, so by slightly raising the closing member, the inner The shoji can be made higher than the guide rail for the inner shoji and the rain return piece, and as a result, even if the sash is a soundproof sash that has a large step for collecting water on the outdoor side of the guide rail for the inner shoji, the inner shoji can be easily moved indoors. There are safety effects that can be removed. In addition, since the bottom frame has a large stepped section for water storage, this bottom frame can be used as the bottom frame for regular sashes, and the bottom frame for soundproof sashes that can be taken in and out can be manufactured at the same time as the bottom frame for regular sashes, allowing for mass production. This has the effect of reducing costs.
