The height adjusting members 83, and the height adjusting member 83 and the bottom 81b are connected by a removable piece (not shown). The removal piece is much smaller than the height adjustment member 83.

  The pressing lip 84 presses the inner surface of the water-stop groove 44b when the receiving member 8 is installed in the water-stop groove 44b of the frame body 4, so that the water-stop groove 44b of the receiver 8 is The falling off from the frame body 4 is regulated. Further, when the receiving material 8 is mounted in the water stop groove 44b of the frame body 4, the pressing lip 84 is caused by a reaction force when pressing the inner surface of the water stop groove 44b as shown in FIG. In addition, the interval between the front end portions of the parallel part 81a of the receiving body 81 is narrowed to restrict the water-stopping rubber 7 from dropping off from the receiving body 81.

  A plurality of gremon handles 9 are provided on the door body 5 and displace the door body 5 from the non-water-stop position to the water-stop position when the water pressure is not applied. The gremon handle 9 includes a handle portion 91 that is rotatably provided on the door body 5 and a convex portion 92 that is provided on the frame body 4. The handle portion 91 includes an operation portion 91a that is provided on both the outdoor space side and the indoor space side and can be gripped by a user, and a ride-up portion 91b that is provided integrally with the operation portion 91a on the indoor space side. Yes. The convex portion 92 is formed to be convex from the surface of the vertical frame member 41 of the frame body 4 on the indoor space side, and the ride-up portion 91b rides to displace the door body 5 from the non-water-stop position to the water-stop position. Is. In this embodiment, a total of four gremon handles 9 are provided, two at the central portion in the vertical direction of the door body 5 and two at the lower end.

  When the water stop door 1 configured as described above enters and exits the structure S through the opening O, the user operates the door knob 54 and the like to move the door 5 to the open position by the biaxial hinge 55. It is rotated over the non-water stop position of the closed position. The water stop door 1 opens and closes the opening O. At this time, even if the door body 5 is in the closed position, the waterproof rubber 7 does not contact the door body 5 and the seal rubber 6 contacts the door body 5 as shown in FIGS. Elastically deforms in contact.

  And when the water stop door 1 stops the opening O, a user rotates the gremon handle 9. Then, the climbing part 91b of the gremon handle 9 rides on the convex part 92, and moves the door body 5 from the non-water stop position to the water stop position toward the indoor space. In the state where the door body 5 is in the water stop position, as shown in FIGS. 3 and 5, the water stop rubber 7 comes into contact with the door body 5 and is elastically deformed, and is in close contact with the door surface material 52 of the door body 5. The water between the door 5 and the frame 4 is stopped.

  Further, the water stop door 1 has a door surface material 52 of the door body 5 in which both the frame contact surface 71a of the mounting portion 71 of the water stop rubber 7 and the door contact surface 72c of the contact portion 72 are closed. And the door body 5 moves from the non-water stop position to the water stop position along the pressing direction P. For this reason, when the door body 5 moves from the non-water stop position to the water stop position, the water stop door 1 approaches the door surface material 52 while the door body contact surface 72c is parallel to the door surface material 52. It will abut. Therefore, the water stop door 1 has the entire frame body contact surface 71 a in contact with the frame body 4 via the receiving member 8 and the entire door body contact surface 72 c is the door surface material of the door body 5 at the water stop position. 52. Therefore, since the water stop rubber 7 is in surface contact with both the frame body 4 and the door body 5 over the entire circumference in the water stop position, the water stop rubber 7 stops the opening O. Can do.

  Furthermore, when the water pressure acts on the outdoor space side of the door body 5 at the water stop position, the water stop door 1 is pressed against the indoor space side, in other words, the frame body 4 side along the pressing direction P. In addition, water enters between the frame body 4 and the door body 5. The water pressure that has entered between the frame body 4 and the door body 5 acts in the direction of crushing the lip portion 65 of the seal rubber 6. When the hydraulic pressure of water that has entered between the frame 4 and the door body 5 exceeds the elastic restoring force of the lip portion 65 of the seal rubber 6, the hollow lip portion 65 is crushed and the water flows into the waterproof rubber 7 and the door. It enters between the body 5. Then, since the distance D1 from the connection part 73 of the one end part 72a of the contact part 72 of the water stop rubber 7 is formed large, the water pressure of the water that has entered between the water stop rubber 7 and the door body 5 is The one end portion 72 a of the abutting portion 72 of the water blocking rubber 7 acts in the direction in which the one end portion 72 a is in close contact with the door surface material 52 of the door body 5. Therefore, even if water pressure acts on the door body 5 at the water stop position, the water stop door 1 can ensure proper water stop performance.

  According to the water stop door 1 according to the embodiment described above, the water stop rubber 7 is attached to the frame body 4 via the receiving member 8 that reduces and fixes the attachment portion 71 of the water stop rubber 7. For this reason, even if a dimensional error occurs in the water stop rubber 7 during molding, the dimensional error of the mounting portion 71 of the water stop rubber 7 is absorbed by the receiving material 8. For this reason, even if a dimensional error occurs in the water-stopping rubber 7 during molding, the dimensional error of the water-stopping rubber 7 can be suppressed by the dimensional error of the mounting portion 71. Therefore, the water stop door 1 can suppress the variation in the contact state of the contact portion 72 of the water stop rubber 7 with the door body 5 and can stop the opening O by the water stop rubber 7 and improve the water stop performance. be able to.

  Moreover, since the water stop door 1 is provided with the latching nail | claw 82 in the front-end | tip part of the parallel part 81a of the receiving main body 81, the water stop door 1 can suppress dropping of the water stop rubber 7 from the support material 8. . Moreover, since the water stop door 1 is provided with the press lip 84 which narrows the space | interval between the front-end | tip parts of the parallel part 81a of the receiving main body 81, when the receiving material 8 is attached to the frame 4, from the receiving material 8 The falling off of the water stop rubber 7 can be suppressed.

  Moreover, the water stop door 1 can adjust the relative position of the contact part 72 of the water stop rubber 7 and the frame body 4 by appropriately selecting the number of the height adjusting members 83 of the receiving member 8. It is possible to suppress variation in the contact state between the contact portion 72 and the door body 5.

  Moreover, the water stop door 1 is provided with the solid contact part 72 which contact | abuts the door body 5 in a water stop position, and is more than the distance D1 of the one end part 72a of the outer peripheral side of the contact part 72, and the connection part 73. The water stop rubber 7 is formed so that the distance D2 between the other end portion 72b on the inner peripheral side of the contact portion 72 and the connecting portion 73 is small. The water-stopping rubber 7 can reduce the elastic restoring force of the other end 72b of the contact portion 72 when bent at the corner of the frame 4 or the like. The surface 71a and the door body contact surface 72c can be kept flat. Therefore, even if the water stop rubber 7 is the corner of the frame body 4, the water stop door 1 can contact the frame body 4 and the door body 5 with the entire frame body contact surface 71 a and the door body contact surface 72 c. The opening O can be stopped and the water stopping performance can be improved.

  Further, the water stop door 1 is formed such that the water stop rubber 7 has a lower hardness than the seal rubber 6 that abuts the door body 5 that is rotated in the rotation direction when closed before the water stop rubber 7. . For this reason, the water stop door 1 can further reduce the elastic restoring force of the other end portion 72b of the contact portion 72 when the water stop rubber 7 is bent at the corner of the frame body 4 or the like. Even at the corners, the frame contact surface 71a and the door contact surface 72c can be kept flat.

  Further, since the sealing rubber 6 comes into contact with the door body 5 before the water stopping rubber 7 and is elastically deformed by being pressed from the door body 5, the water stopping door 1 is elastically deformed by the elastic force of the sealing rubber 6. In the closed position and the non-water stop position, the water stop rubber 7 can be prevented from coming into contact with the door body 5 or being elastically deformed by being pressed from the door body 5. Therefore, when the door body 5 opens and closes the opening O, the water stop door 1 can suppress the elastic deformation of the soft water stop rubber 7 with low hardness. It can suppress being beaten. Therefore, the water stop door 1 can stop the water stop rubber 7 between the frame body 4 and the door body 5 at the time of water stop, and can improve water stop performance.

  Further, since the water stop rubber 7 does not come into contact with the door body 5 at the non-water stop position when the water pressure of the door body 5 is not acting, the water stop door 1 stops water when the door body 5 opens and closes the opening O. It is possible to suppress the rubber 7 from being rubbed from the door body 5. Furthermore, even if the water stop door 1 is separated from the door body 5 by water pressure acting on the door body 5 at the water stop position and the lip portion 65 of the seal rubber 6 is crushed, the water stop rubber 7 is formed solidly. Therefore, the waterproof rubber 7 itself is not easily deformed, and the contact portion 72 can be prevented from being separated from the door body 5. Therefore, the water stop door 1 can improve the water stop performance.

  Moreover, since the water stop door 1 is provided with the gremon handle 9 which displaces the door body 5 from a non-water stop position to a water stop position, when the water pressure is not acting on the door body 5, the door body 5 is provided by the gremon handle 9. Can be displaced to the water stop position. For this reason, the whole frame body contact surface 71a of the water stop rubber 7 is displaced by displacing the door body 5 to the water stop position in a state where no water pressure is applied to the door body 5, the seal rubber 6 and the water stop rubber 7. The receiving member 8 can be brought into contact with the frame body 4, and the entire door body contact surface 72 c can be brought into contact with the door body 5. Therefore, the water stop door 1 can improve the water stop performance.

  In the embodiment described above, the water stop door 1 includes the seal rubber 6 that contacts the door body 5 when the door body 5 is opened and closed, and the water stop body 3 that contacts the door body 5 when the opening O stops. However, in the present invention, only the water stop body 3 may be provided as long as the water stop rubber 7 of the water stop body 3 does not wrinkle even if it contacts the door body 5 when the door body 5 is opened and closed. Further, in the present invention, when both the seal rubber 6 and the water stop body 3 are provided, if the seal rubber 6 contacts the door body 5 moving from the open position to the closed position before the water stop rubber 7, Even in the non-water stop position, the water stop rubber 7 may abut against the door body 5 and be elastically deformed.

  In the present invention, the gremon handle 9 need not be provided. Specifically, when the entire frame contact surface 71a of the water blocking rubber 7 is in contact with the frame 4 and the entire door contact surface 72c is in contact with the door 5 at the non-water stop position of the closed position, In the present invention, the gremon handle 9 is not necessarily provided. Further, for example, even if the contact portion 72 does not contact the door body 5 at the non-water stop position of the closed position, when the water pressure acts on the door body 5, the door body 5 is moved in the pressing direction P by the water pressure. When the entire frame contact surface 71a of the water-stopping rubber 7 is in contact with the frame 4 and the entire door contact surface 72c is in contact with the door 5, the present invention does not necessarily include the gremon handle 9. It does not have to be.
