This dead bolt 73 can also be made to appear on the side surface of the door body 5 as the operation shaft 27 rotates. As shown in FIGS. 1 and 4, the dead bolt 73 protruding from the side surface is engageable with an engagement recess 74 formed in the side frames 7 and 8.

  FIG. 4 shows an example in which one fixing member 61 blocks a part of the opening on the upper surface of the apparatus main body 30. In addition, the other fixing member 61 covers a part of the opening on the lower surface of the apparatus main body 30. It is fixed to the inner surface of the door body 5 so as to close it. On the lower surface of the other fixing member 61, a guide rail 66 having the same shape as that in FIG. 4 extends downward in the vertical direction of the door body (the vertical direction in FIGS. 1 and 3). Has been. In addition, a lower rod-like member 64 extending downward from the interlocking member 62 to the door body 5 is connected to the other interlocking member 62 having the same shape as that of FIG. In a normal state where the locking device 20 is not operated, the lower end portion of the lower rod-shaped member 64 is located in the door body 5 as shown in FIG. A lower engagement portion 76 is provided at the lower end portion of the lower rod-shaped member 64. The lower engaging portion 76 has the same shape as the upper engaging portion 68. And the lower through-hole 77 (refer FIG. 1) which connects the inside and the exterior of the door body 5 is formed in the lower surface of the door body 5 facing the lower side engaging part 76. As shown in FIG. Further, as shown in FIG. 1, a lower engagement hole 78 is formed in the lower frame 10 of the door frame 3 at a position facing the lower engagement portion 76 with the lower through hole 77 interposed therebetween.

  In addition, when the operating shaft 27 rotates, the rotating member to which the operating shaft 27 is fixed is a second member that moves in the vertical direction of the door body 5 in the direction opposite to the moving direction of the first moving member. A moving member (not shown) is locked. The second moving member is engaged with the other interlocking member 62 that connects the lower rod-shaped member 64. Therefore, for example, when the operation shaft 27 is rotated together with the operation shaft 26 by the handle 28, the other interlocking member 62 connected to the lower rod-shaped member 64 can be moved up and down as the second moving member moves up and down. Become. From this, the lower engaging portion 76 of the lower rod-shaped member 64 can be projected and retracted in the lower through hole 77. A lower engagement portion 76 that protrudes from the lower through hole 77 to the lower side of the door body 5 is engageable with a lower engagement hole 78 shown in FIG. The lower engagement hole 78 is an example of a lower receiving portion of the present invention.

  Next, the operation | movement which makes the closed state which operates the locking device 20 and the door body 5 closes the opening part 4 of the door frame 3 is demonstrated. For example, as indicated by a two-dot chain line in FIG. 2, when the door 5 opens the opening 4, a person holds the handle 28 and rotates the door 5 toward the opening 4. Then, the door body 5 is opened so that the packing pressing member 17 (see FIG. 4) of the door body 5 abuts the packing 13 (see FIGS. 2 and 3) disposed on the inner surface of each frame 7-10. 4 is inserted.

  Subsequently, when the operation shaft 27 is rotated together with the operation shaft 26 by a person operating each handle 28 to rotate to the lock position of the door body 5, the upper rod-shaped member 63 moves upward in the door body 5. And the lower rod-shaped member 64 moves downward in the door body 5. As a result, the upper engagement portion 68 of the upper rod-shaped member 63 protrudes from the upper through hole 70 to the upper side of the door body 5 and engages with the upper engagement hole 71, and the lower engagement of the lower rod-shaped member 64. The part 76 protrudes downward from the lower through hole 77 to the door body 5 and engages with the lower engagement hole 78. At that time, the inclined surface of the upper engaging portion 68 moves toward the inlet of the upper engaging hole 71 so as to ride on the inlet portion of the upper engaging hole 71, and the inclined surface of the lower engaging portion 76 is inclined. The surface moves toward the entrance of the lower engagement hole 78 so as to ride on the entrance of the lower engagement hole 78. By doing in this way, the upper engaging part 68 moves the door body 5 toward the inside of the building 2 after entering the upper engaging hole 71. In addition, the door 5 is also moved toward the inside of the building 2 for the lower engaging portion 76 that has entered the lower engaging hole 78. Accordingly, as shown in FIG. 4, the packing pressing member 17 of the door body 5 can be pressed against the packing 13. As a result, the packing 13 is elastically deformed and comes into close contact with the packing pressing member 17. Therefore, it is possible to seal between the packing 13 of each frame 7 to 10 and the packing pressing member 17 of the door body 5. Therefore, in the closed state, it is possible to prevent water from entering between the door body 5 and the door frame 3 (the frames 7 to 10). Then, as in this embodiment, the upper engagement portion 68 of the upper rod-shaped member 63 is engaged with the upper engagement hole 71 and the lower engagement portion 76 of the lower rod-shaped member 64 is engaged with the lower side. By adopting a simple structure in which the packing pressing member 17 of the door body 5 is pressed against the packing 13 by engaging with the hole 78, the packing 13 of each frame 7 to 10 and the packing pressing member of the door body 5 are inexpensive. 17 can be sealed.

  Furthermore, in this embodiment, as shown in FIG. 4, the gap between the periphery of the mounting member 21 mounted in the first through hole 31 and the inner surface of the fitting hole 41 can be closed by the O-ring 23. In addition, the O-ring 24 can block the gap between the opening 50 at the end of the second through hole 35 on the inner side of the building 2 and the operation shaft 26 (shaft portion 47). From these things, even when an opening part (the 1st penetration hole 31, opening 50) is provided in order to make operation shaft 26 project from surface 5A of door 5, flooding from these opening parts can be controlled. For example, even if the handle 29 (third through hole 55) is submerged due to water damage or the like in the closed state of the opening 4, even if the inside of the door body 5 is submerged from the third through hole 55, the O-rings 23, 24 are used. Thus, it is possible to suppress the water that has entered the inside of the door body 5 from entering the inside of the building 2 of the door frame 3 from the opening portion.

  4 can be removed from the fitting hole 41 through the first through hole 31 by releasing the screwing of the screw member 44 to the screw holes 38 and 42 shown in FIG. Since the O-ring 23 is externally mounted on the mounting member 21, and the O-ring 24 is mounted on the inner end of the building 2 in the second through hole 35 of the mounting member 21, the mounting member 21 is attached to the mounting member 21. The O-rings 23 and 24 can be inspected and replaced while being removed from the fitting hole 41. Therefore, inspection and replacement of the O-rings 23 and 24 are facilitated.
