TECHNICAL FIELD The present invention relates to a waterproof door,
Particularly, the present invention relates to a waterproof door that can be easily opened and closed.

[0002]

2. Description of the Related Art Conventionally, a waterproof door is generally provided in an entrance passage of a parking lot in an underground parking lot or the like in order to prevent inflow of flowing water due to flooding of a river.

A waterproof door is rotatably supported on a side wall of a passage or the like via a hinge, and is normally fixed to a storage position parallel to the passage, and is displaced and fixed to a closed position crossing the passage only when necessary. To prevent running water from entering.

In this type of waterproof door, generally, stepped portions 52a and 54a are formed on a side wall 52 and a bottom wall 54 of a passage 50 as shown in FIG. 4, and when a door body 56 is set to a closed position (shown in FIG. 4). ), The seal member 58 provided over the edge of the door main body 56 has the stepped portion 52a,
54a, whereby the space between the door body 56 and the side wall 52 and the like is sealed.

[0005]

In the conventional waterproof door as described above, it is necessary to enhance the sealing effect by pressing the sealing member 58 firmly against the stepped portion 52a or the like so as to withstand the water pressure. After the door body 56 is set to the closed position, the door body 56 is connected to a fastening means (not shown), and the door body 56 is pulled in the closing direction (the direction of arrow A in the figure) and fixed by the fastening means.

However, this fastening means requires an excessive amount of labor because it is configured to pull the door body 56 in the closing direction against the elastic force of the seal member 54a. For this reason, with the conventional waterproof door, it was difficult for the elderly or women and women to close the door. However, since the waterproof door is usually closed in an emergency, it is necessary to ensure that the waterproof door can be closed regardless of the worker.

[0007] The present invention has been made in view of the above problems, and has as its object to provide a waterproof door capable of easily performing an opening and closing operation while ensuring a waterproof (waterproof) function. .

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a door body which is rotatable between a storage position arranged substantially parallel to a passage and a closed position arranged across the passage. In a waterproof door that has a, closing the passage by setting the door body in the closed position and waterproofing inflow of running water,
A seal member that seals between a passage wall surface and a door body in a closed position is provided on a door body, and the seal member is provided with a hydraulic pressure operating surface that is inclined from a passage center side toward a passage wall side toward a passage entrance. (Claim 1).

According to this waterproof door, the inflow of flowing water is prevented by setting the door body at the closed position. The seal between the passage wall surface and the door body is sealed by a seal member. At this time, when water pressure acts, the seal member is pressed against the passage wall surface by the water pressure due to the inclined working surface as described above. As a result, the space between the passage wall surface and the door body is reliably sealed. In other words, when the door body is closed, the seal member and the passage wall surface may be appropriately pressed against the design, so that it is not necessary to press the seal member and the wall surface firmly in advance as in the related art. .

As a specific configuration, of the sealing member, a side edge for sealing between the door body and the passage side wall is formed so as to expand toward the passage entrance, and a gap between the door body and the passage bottom wall is formed. The bottom edge for sealing can be formed downwardly toward the passage entrance (claim 2).

In the case where a narrow portion is formed in the passage and a seal member is provided so as to seal between the wall surface of the narrow portion and the door body, the seal member is closed with the closing operation of the door body. It is preferable that a tapered guide surface for guiding into the narrow portion is formed in the narrow portion (claim 3).

With this configuration, since the seal member is smoothly guided into the narrow portion, it is possible to prevent troubles such as the seal member catching on the edge of the narrow portion during the closing operation of the door body. .

Preferably, the portion of the seal member that contacts the wall surface of the passage is made of a low friction material that reduces frictional resistance with the wall surface of the passage.

[0014] In this case, the sliding resistance between the sealing member and the wall surface of the passage is reduced, and the labor for opening and closing operations can be further reduced.

As means for fixing the door body at the storage position or the closed position, a fixed portion is provided on the door body, while a fixed portion corresponding to the fixed portion is provided at the storage position and the closed position, and the door body is fixed. In a state where the door body is set in the storage position or the closed position, it is preferable that the door body is fixed to the storage position or the closed position so as not to rotate by inserting a pin member through the fixed portion and the fixed portion. (Claim 5).

In this case, the door body can be easily fixed or released simply by inserting and removing the pin member.

The distance between the bottom edges 14b of the sealing member 14 and the relative height of the bottom edges 14b with respect to the road surface 4 are determined when the door body 10 is set to the closed position.
The design is set so that the sealing member 14 is pressed against the partition walls 2 and 3 and the road surface 4 at an appropriate pressure by the elastic force of each of the portions 14a and 14b. Further, the distal end portion of the seal member 14 (the distal end portion of the side edge portion 14a and the bottom edge portion 14b) has a rounded cross-sectional shape as shown in FIG. The seal member 14 is configured to be able to slide smoothly on the side walls 2a, 3a and the road surface 4.

Tapered portions 2b and 3b (guide surfaces) are formed at end portions of the partition walls 2 and 3 of the passage 1 (end portions opposite to the passage entrance side; upper ends in FIG. 2). Further, both side edge portions 14a of the seal member 14 are guided between the side walls 2a, 3a of the partition walls 2, 3 with the closing operation of the door body 10. As shown in FIG. 3, the road surface 4 on the rear side of the door main body 10 in the closed position (the side opposite to the entrance side of the passage; the right side in FIG. 3) is slightly lower via the slope 4a. At the time of closing of 10, the sealing member 14 (bottom edge portion 14b) and the road surface 4 are not in contact with each other until immediately before the closing position, and then the bottom edge portion 14b is pressed against the road surface 4 at the closing position while being guided along the slope 4a. It is supposed to.

As shown in FIG. 1, the above waterproof door is further provided with a patrol light 28 as a safety device, which is operated by a safety switch 24 provided near the hinge 12 of the door body 10. Have been. That is, as shown in FIG. 2, a contact 11 is provided at the base end portion of the door body 10, and when the door body 10 is in the retracted position, the lever 26 of the safety switch 24 is set to the contact 11
And the safety switch 24 is turned off. On the other hand, when the door body 10 is displaced from this storage position to the closed position, the lever 26 is returned by the urging force of a spring (not shown) and the safety switch 24 is turned on. It is configured to be. When the safety switch 24 is turned on, the patrol light 28 is turned on, thereby notifying that the door body 10 has been set to the closed position. In the central part of the door body 10,
As shown in FIG. 1, a mark 20 made of a fluorescent paint or the like is marked, thereby enhancing nighttime alertness when the passage 1 is in a closed state.

The above-mentioned waterproof door is usually fixed in a storage position, whereby the passage 1 is opened so that vehicles can pass through the underground parking lot.

Then, flowing water is caused by passage 1 due to flooding of the river.
If there is a possibility that the water flows into the underground parking lot, the door body 10 is fixed to the closed position to prevent the inflow of flowing water into the underground parking lot. Specifically, the door body 10 is fixed at the closed position according to the following procedure.

First, the fixing pin fixing the door body 10 to the storage position is pulled out. That is, the fixing pin inserted through the fixing fitting 13 and the locking fitting 5 of the door body 10 is pulled out, and the engagement state of the fittings 5 and 13 is released.

Next, the handle 18 (see FIG. 1) is gripped,
The door body 10 is turned to set the door at the closed position. At this time, the taper 2b, 3b is formed on the side walls 2a, 3a of the partition walls 2, 3, and the slope 4a is formed on the road surface 4, so that the seal member 14 is caught on the edge of the partition walls 2, 3. The door main body 10 is guided to the closed position without performing the same. Further, since the distal end portion of the seal member 14 has a rounded shape, the seal member 14 slides smoothly on the side walls 2a, 3a and the road surface 4. Therefore, the door body 1 can be easily operated simply by pressing the door body 10.
0 can be set to the closed position.

After the door main body 10 is set at the closed position, the fixing pin is finally inserted over the locking metal 6 and the fixing metal 13 to fix the door main body 10 at the closed position. Thereby, the closing operation of the door body 10 is completed. The door body 1

When the door body 10 is fixed at the closed position in this way, the water is blocked by the door body 10 and the inflow of the water into the underground parking lot is prevented. At this time, since both side edge portions 14a of the seal member 14 are formed so as to protrude toward the passage entrance side, and the bottom edge portion 14b is formed so as to descend toward the passage entrance side, the flowing water is blocked. When the seal member 14 is stopped and a water pressure (indicated by a symbol P in FIGS. 2 and 3) is applied to the seal member 14, the side edge portions 14a are pressed against the side walls 2a and 3a of the partition walls 2 and 3 as described above. The bottom edge portion 14 b is bent and pressed against the road surface 4. Therefore, the door body 10 and the passage 1
And the side wall portion is strongly sealed in accordance with the water pressure, and as a result, intrusion of flowing water is reliably prevented.

According to the above-described waterproof door, since the sealing member 14 is formed so as to tightly seal between the door body 10 and the passage wall surface by the action of the water pressure as described above, In the operating state, it is sufficient that the seal member 14 is appropriately pressed against the passage wall surface. It is necessary that the seal member 14 and the passage wall surface be firmly pressed against each other when the door body 10 is set to the closed position. There is no. That is,
The door body 10 may be configured so that the seal member 14 is appropriately pressed against the passage wall surface when the door body 10 is closed, so that the sliding resistance between the seal member 14 and the passage wall surface during opening and closing operations is reduced. The door body 10 can be opened and closed with a correspondingly small amount of labor. Further, unlike the related art, it is not necessary to firmly pull and fix the door body 10 by the fastening means.

In addition, since the door body 10 can be opened and closed simply by inserting and removing the fixing pin and rotating the door body 10, the door body 10 can be opened and closed with a very simple operation.

Therefore, according to the above-mentioned waterproof door, the waterproof (waterproof) performance equivalent to that of the conventional waterproof door is ensured, but the door body is extremely simple and requires less labor than the conventional waterproof door. There is an effect that 10 can be opened and closed.

Further, in the conventional waterproof door, since the sealing member provided on the door body is pressed against the step portion (see FIG. 4) of the road surface, the step portion is always required on the road surface. Although there is a problem such as giving a passenger an unpleasant feeling while the vehicle is running due to the presence, according to the waterproof door of the above embodiment,
Since such a stepped portion is not formed on the road surface 4, there is also an effect that the occupant does not feel uncomfortable during traveling.

In the above waterproof door, the door body 1
0 is made of a lightweight metal material such as aluminum to reduce the weight, or the tip of the seal member 14 is coated with a low friction material such as Teflon resin to form the side walls 2a,
You may make it improve the slidability of the sealing member 14 with respect to 3a etc. In this way, the door body 10 can be more easily opened and closed.

Also, the partition walls 2 and 3 are omitted, the door body 10 is directly rotatably supported on the side wall of the passage 1, and the space between the door body 10 and the side wall of the passage is sealed by a seal member 14. You may. In this way, the width of the passage can be widened as much as the partitions 2 and 3 can be omitted.

Further, in the above embodiment, the door body 10
Are supported so as to be rotatable about a vertical axis.
0 may be, for example, one that is supported on a passage ceiling or the like so as to be rotatable around a horizontal axis.

Further, the waterproof door of the above embodiment is provided with the passage 1
Is configured to be partially closed by the door body 10 (for example, the entire passage may be completely closed (closed)). In this case, the sealing member 14
It is necessary to provide a part for sealing between the door body 10 and the passage ceiling, but this part
Similar to 4a and 14b, it may be formed so as to rise toward the entrance side of the passage 1 so that the portion is pressed against the ceiling wall by water pressure.

It should be noted that the sealing member 14 is provided with a hydraulic pressure acting surface (surface 1) so as to be pressed against the passage wall surface when receiving the water pressure.
5 and 16) may be any shape as long as they are inclined toward the passage entrance side. For example, in the side edge portion 14a of the seal member 14, the surface (outer surface) facing the side walls 2a, 3a does not necessarily need to be inclined if the surface 15 is inclined, and is parallel to the side walls 2a, 3a. Surface. Similarly, in the bottom edge portion 14b, the surface facing the road surface 4 may be parallel to the road surface 4 if the surface 16 is inclined.
