The waterproof door device 1 is provided with a seal mechanism 20 that seals between the waterproof doors 3 and 3 at the standing position. Hereinafter, the seal mechanism 20 will be described in detail.
As shown in FIGS. 6 to 8, first, protrusions 21, 21 are integrally fixed to the door portions 9 of the both waterproof doors 3, 3 along adjacent edges. The protruding portion 21 is a rectangular rod-like body in plan view having a length that reaches the lower end of the door portion 9 from a position slightly lower than the door portion 9, and the rear surface is the front position of the case 2 at the standing position of the waterproof door 3. It is located on the extension of the back surface of the wall 2a. Further, the interval between the opposing side surfaces of the protrusions 21 and 21 is slightly wider than the gap between the doors 9 and 9. Further, a screw hole 22 is formed orthogonally on the side surface opposite to the facing surface of each protrusion 21, and a hexagon bolt 23 as a locked portion is screwed into the right screw hole 22. ing.

On the other hand, an arm member 24 is connected to the bottom surface of the case 2 between the waterproof doors 3 and 3. The arm member 24 is a rod-like body that is pivotally attached to a support base 25 projecting on the bottom surface of the case 2 by a support shaft 26 in the left-right direction. Further, the arm member 24 has a lying posture (the position indicated by a two-dot chain line in FIG. 6) that lies laterally below the waterproof door 3 in the lying position and a standing posture that stands up behind the waterproof doors 3 and 3 in the standing position ( 6, and is urged to the standing posture side by a gas spring 27 as urging means installed between the back surface and the back surface of the support base 25. In this standing state, the upper end of the arm member 24 is substantially the same height as the ridge 21.
Further, a water stop rubber 29 as a water stop member is held on the front surface of the arm member 24 via a U-shaped holder 28 in plan view. The water blocking rubber 29 has a rectangular cross section whose front surface projects forward from the holder 28, the upper end substantially coincides with the upper end of the ridge portion 21, and the lower end is waterproof beyond the lower end of the ridge portion 21. The length reaches the lower end of the base end portion 8 of the door 3.

In addition, on the side surface of the arm member 24, one end of a link plate 30 as a link member is inserted from the outside as shown in FIG. 8 at a position above the hexagon bolt 23 of the protrusion 21 in a standing posture. The pin 31 is rotatably mounted on the shaft. Reference numeral 32 denotes a set screw that is screwed from the back surface of the arm member 24 and is locked to the pin 31.
At the other end of the link plate 30, an intermediate portion of the operation lever 34 is rotatably mounted by a reamer bolt 33 press-fitted from the inside. The operation lever 34 is a rod-like body that is longer than the link plate 30, and is provided with a hook 35 that can be locked to a hexagon bolt 23 that is screwed into the protrusion 21 at one end.
Further, as shown in FIG. 9, a stopper bolt 36 as a stopper member with a collar 37 is screwed onto the side surface of the arm member 24 below the hexagon bolt 23. The stopper bolt 36 serves as a stopper for regulating the lower limit position of the operation lever 34 in which the hook 35 is engaged with the hexagon bolt 23.

  On the other hand, as shown in FIG. 10, a block 38 containing a plunger 39 is fixed to the back surface of the arm member 24 with bolts. The plunger 39 is held in a state in which the ball 40 provided at the tip protrudes from the side surface of the block 38. When the operation lever 34 is erected along the arm member 24, the head of the reamer bolt 33 is placed on the ball 40. The hexagonal hole 33a provided in the part is fitted to hold the operating lever 34 in the standing posture as shown in FIG. The link plate 30 is formed with a notch 41 that prevents interference with the stopper bolt 36 when the operation lever 34 is in the standing posture.

In the waterproof door device 1 configured as described above, when the waterproof doors 3 and 3 are not used, the operation lever 34 of the seal mechanism 20 is placed along the arm member 24 and the ball 40 of the plunger 39 as described above. The hexagonal hole 33a of the reamer bolt 33 is fitted into the. Therefore, at the fall position of the waterproof doors 3, 3, the operation lever 34 does not get in the way as shown by a two-dot chain line in FIG.
When the waterproof doors 3 and 3 are used from here, the lid member 10 is removed and the upper ends of the waterproof doors 3 and 3 are lifted up. Then, the chain 14 and the lock arm 15 extend to hold the waterproof doors 3 and 3 in the upright position, and the seal member 7 on the outer edge of the waterproof doors 3 and 3 comes into contact with the contact frame 6.

When the waterproof doors 3 and 3 are erected, as shown in FIG. 11A, the arm member 24 is erected by the urging of the gas spring 27, and the waterproof rubber 29 is straddled across the back surfaces of the ridges 21 and 21. Make contact. However, in this case, the arm member 24 is in a vertical posture in which the arm member 24 is parallel to the ridge portion 21, and the horizontal distance between the back surface of the ridge portions 21, 21 and the front end of the holder 28 is a water stop protruding from the holder 28. Since the protruding amount of the rubber 29 is set smaller, in the standing posture of the arm member 24, the lower part of the water blocking rubber 29 comes into contact with the protrusions 21, 21 first, and the arm member 24 is inclined slightly rearward. It becomes a state.
Here, the operation lever 34 is removed from the ball 40, the hook 35 is rotated forward, and the hexagon bolt 23 is locked from above as shown in FIGS. In this state, the operation lever 34 is inclined to protrude rearward and upward, and the link plate 30 is also inclined to protrude the upper end rearward of the arm member 24.

  When the rear end of the operation lever 34 is pushed downward from here, the operation lever 34 rotates around the hexagon bolt 23 as shown in FIG. 11D, and the reamer bolt 33 is moved downward to rotate the link plate 30. . Since the distance between the hexagon bolt 23 and the reamer bolt 33 does not change, the end portion on the pin 31 side of the link plate 30 moves forward to press the arm member 24 forward. Accordingly, the water stop rubber 29 is pressed and compressed by the two ridges 21, 21, and is pressed against both the ridges 21, 21 over the entire length, so that the arm member 24 assumes a vertical posture. As shown in FIG. 11D, the pressing force becomes maximum when the operation lever 34 and the link plate 30 overlap each other on the same straight line.

  When the operation lever 34 is further pushed down and comes into contact with the stopper bolt 36, as shown in FIG. 11E, the operation lever 34 stops in an inclined posture in which the rear end is slightly lower than the front end. At this time, the link plate 30 has an end portion on the pin 31 side located above the center line of the operation lever 34 and has a downward inclined posture having a larger angle than the operation lever 34, so that the operation lever 34 is rotated upward. Is regulated. Even in this position, the state in which the water stop rubber 29 is pressed against both the protrusions 21 and 21 over the entire length is not changed, so that the gap between the protrusions 21 and 21 is sealed by the water stop rubber 29. It will be.

The pressing force can be easily adjusted by changing the length of the link plate 30 or changing the diameter of the collar 37 to be externally attached to the stopper bolt 36. FIG. 12 shows an example in which the diameter of the collar 37 is increased. In this case, the lower limit position of the operation lever 34 to be pushed down is higher than that in FIG. 11E and approaches the posture of FIG. Therefore, the pressing force increases. On the contrary, if the diameter of the collar 37 is reduced, the pressing force is reduced. In the case of a link plate, a longer pressing force increases the pressing force.
On the other hand, the waterproof rubber 29 on the lower side of the door portion 9 presses the back surface of the front wall 2a across the front seal members 12, 12 and the back seal member 13, and thus the door portions 9, 9 and the front wall 2a Is sealed.

In order to release the seal, in reverse to the above procedure, the rear end of the operation lever 34 is pushed upward to release the pressing of the arm member 24 and the hook 35 is removed from the hexagon bolt 23.
Subsequently, when the waterproof doors 3 and 3 are laid down, after the operating lever 34 is held in the holding posture along the arm member 24, the extension of the lock arm 15 is released and the waterproof doors 3 and 3 are tilted backward, The member 24 is also pushed by the protrusions 21 and 21 against the bias of the gas spring 27 and rotates to the lying posture.

  Thus, according to the sealing mechanism 20 of the waterproof doors 3 and 3 and the waterproof door device 1 of the above-described form, the protrusions adjacent to each other with a predetermined gap at the standing position on the edge of the waterproof doors 3 and 3. 21 and 21, respectively, while standing on the back side of the ridges 21 and 21 along the ridges 21 and 21, and a lying posture lying below the waterproof door 3 in the lying position The arm member 24 is provided with a water stop rubber 29 that can be rotated between the pair of protrusions 21 and 21 in a standing posture, and the arm member 24 projects in the standing posture. The pressing means (link plate 30) is engaged with the ridges 21 and 21 to urge the arm member 24 toward the ridges 21 and 21 and press the water stop rubber 29 over the entire length of the ridges 21 and 21. , Operation lever 34, stopper bolt 36, etc.) Reliable sealing is possible if a large pressing force is obtained by Do configuration. In addition, since it is possible to easily adjust the pressing force at the site, unnecessary labor and cost are not required. Furthermore, since the seal mechanism 20 is provided exclusively on the arm member 24 separate from the waterproof doors 3 and 3, the order of raising the waterproof doors 3 and 3 is not restricted. Therefore, quick standing of the waterproof doors 3 and 3 can be secured.

  In particular, here, the pressing means includes a link plate 30 whose one end is rotatably connected to the side surface of the arm member 24, and an intermediate portion is rotatably connected to the other end of the link plate 30. 21 is provided with a hook 35 that can be engaged with and disengaged from the hexagon bolt 23 provided on the side surface of the member 21, and the other end is pushed downward while the hook 35 is locked to the hexagon bolt 23. An operation lever 34 that urges the arm member 24 toward the ridge portion 21 side and an operation lever 34 that is provided below the connection position of one end of the link plate 30 on the side surface of the arm member 24 and that has been pushed down contact each other. Since it is configured to include a stopper bolt 36 that positions the center line of the operation lever 34 below the connecting position of one end of the link plate 30 in the abutting state. It is possible to form easily a means, adjustment of the pressing force is also easy to, there is no need to increase the manufacturing accuracy. Therefore, it leads to cost reduction.

Further, by providing a holding mechanism for holding the operation lever 34 in a posture along the arm member 24 on the back surface of the arm member 24, the operation lever 34 can be easily operated, and the operation lever 34 can be operated when the waterproof door falls down.
