When the pull handles 68 and 69A are simultaneously moved to the pull position in the closed state, they engage with the engaging portion 85 of the mating sliding door 22, causing the butt pivot 26 to move toward the outdoor side with respect to the stile 26. Its position is set so that it will attract you. In addition, a stopper (not shown) is attached to the abutting portion of the upper frame 2 and the lower frame 3 for receiving the pullers #22 and 23 in the closed position.

In the case of configuration 1, the pulling handle 6 of the sliding door 22
8. In the state in which 69 is rotated to the separated position, the elevating plate 43
The engaging hole 89 of the locking lever 92 faces the locking pin 94, and when the sliding door 22 is opened in this state, the locking lever 92 is rotated by the spring force of the torsion spring 95, as shown in Fig. 915. Holding bottle 94
is fitted into the engagement hole 89. Therefore, when the sliding door 22 is open, the upward movement of the lifting plate 43 is stopped by the lock pin 94, and even if the pulling handles 68, 69 are attempted to be rotated to the pulling position, the movement is blocked. The puller 76 on the lifting plate 43 is maintained at a position where it does not face the engaging portion 86b of the tool 86. In addition, when the pulling handle 6B is rotated to the 69ft pulling position, the pulling piece 77 of the safety device 97 is raised as shown in Figure @14, and the bottom surface of the guide groove 98 is raised above the top of the guide rail 11. When the sliding door 22 is opened in this state, the guide groove 98 is smoothly fitted into the guide rail 11, and the groove bottom is positioned above the top of the fifth guide rail 11.

In this way, when the sliding door is open, the pulling roller 76 is maintained at a position where it does not face the engaging portion 8613, so that a collision between the pulling roller 76 and the engaging portion 86b is prevented when the sliding door 22 is closed. Ru. Furthermore, as is clear from the above, the safety device 88
．． Either one of 97 and 17 may be omitted. The seven things explained above can be said to be exactly the same for the other sliding door 25.

Next, in order to airtightly close the sliding door 22, 23, when the sliding door 22 is first moved to the closed position, the tip of the locking lever 92 of the safety device f188 comes into contact with the catch piece 96, and the locking lever 92 is rotated, whereby the hook 94 is removed from the hook hole 89. Further, when pulling the safety equipment fl197, the piece 77 is positioned so as to face the notch 99 of the guide rail 11, and the guide groove 98 is positioned so that the guide rail 11
removed from Therefore, the elevating plate 45 can be raised, the elevating plate 42 can be lowered, and the pull handle 68, A1
9 69 can now be rotated to the drawn position. When the pulling handles 68 and 69 are rotated to the pulling position using this mechanism, the elevating plate 42 and the pulling piece 77 are lowered, and the inclined surface 78 of the pulling piece 77 is brought into contact with the corner 79 of the lower frame 5. , and pulls the lower part of the butt stile 26 toward the outdoor side. In addition, the interlocking plate 5
5 is moved in the sliding door closing direction, the pulling roller 81 engages with the engaging portion 87b of the pulling member 87, and the upper stile 24 of the sliding door 22 is moved.

The closing and pulling operations described in 3 may be performed at the same time. next,
If you want to open the sliding door 22, 23, press the pull handle 6.
This can be done by rotating 8.68mm and 69.69mm to the separation position. The above-mentioned pulling and pulling operations of the sliding doors 22.23 can be easily performed by operating the pulling handle 21F 68.68 or 69.69A provided at one location of the four doors 22.23. In addition, since the pull handles 68.68 and 69.69 are provided on the indoor side and the outdoor side, respectively, the sliding door 22.23 can be pulled in and pulled out from the indoor side like a conventional soundproof door. This can be done even from the outside of the room by operating the pull handles 68.68mm and 69.69mm. In addition, in the present invention, one of the seven t1 1 notes Lχ is set at 0° or more, so that the butting point of both sliding doors is 0° or more. Elevating and lowering members that can be raised and lowered by pull handles are respectively disposed on the and stile, and an interlocking member that moves in conjunction with the elevating member is placed on the upper stile, and the upper and lower parts of the elevating member of the stile are arranged. A pulling engagement member is attached to the lower end of the abutting elevating member and the butting root side of the interlocking member, respectively, and the opening frame is engaged with each of the pulling engaging members that are moved when the sliding door is closed to move them into the room. Since we have provided separate parts for the sliding doors that can be pulled towards the inside or the outdoor side, by closing both sliding doors and pulling the pull handles, you can pull the entire sliding door straight towards the indoor side or the outdoor side. As a result, each group of sliding doors can be strongly pressed against the airtight material of the opening frame without prying it, and it is possible to close the space between both sliding doors and the opening frame in a highly airtight manner, and to maintain its performance over a long period of time. There are advantages that can be maintained. In addition, since the lifting and lowering members and interlocking members of the sliding door are operated by operating the pulling handle, even if the sliding door can be pulled straight to the indoor side or the outdoor side as described above, the sliding door cannot be pulled straight. , pulling, and operation can be performed by operating only one pulling handle, and both sliding doors can be operated.
It can be installed from both the indoor and outdoor sides like a door, and can be used as an alternative to conventional soundproof doors, as well as in places where it is difficult to install soundproof YA due to space constraints. There are possible advantages.
