Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a tide door constructed by integrally providing a waterproof plate at the lower end of a shutter curtain.

[Problems to be solved by the prior art and the invention]

Conventionally, as a tide door with a waterproof plate integrally attached to the lower end of the shutter curtain, for example,
The prior art is known as shown in Japanese Patent No. 58-9979. By the way, regarding the water tightness between the floor surface and the bottom surface of the tide barrier board,
Since the waterproof board comes into contact with the floor with the weight of the shutter curtain added to its own weight, the required watertightness can be ensured by providing an appropriate seal on the bottom of the waterproof board. The problem is ensuring watertightness between the guide rail and the waterproof board, which does not bear its own weight.

Therefore, in the prior art, a pair of upper and lower rollers are provided at both ends of the waterproof board, with the left and right positions shifted, and an inclined guide is provided on the guide rail to guide the rollers indoors. The waterproof board that has been lowered to the closed state is guided so that it comes into contact with the indoor side surface of the guide rail, and the guided waterproof board is hinged to the waterproof board so that it can swing freely. The seals provided on both the left and right sides of the seawall were pressed against the guide rail by performing a swinging operation to engage the notch engaging portions provided in the sections.

However, in this case, it is necessary to process the guide rail into a special one in which a notch engaging portion for engaging the pressing tool is formed in the middle, and the notch engaging portion is not exposed to the outside. Not only is it exposed and undesirable in appearance, but there is also the risk that a child may insert their finger here and injure themselves, or that an unscrupulous person may force chewing gum or dirt into the notch and block it. Moreover,
The guide rail itself must have enough engagement allowance for the pressing tool, so it must protrude inward from the left and right edges of the opening by at least that amount.As a result, the width of the left and right frontage of the opening This creates a problem in that the guide rail itself must be strong, as it becomes narrow and the sense of openness is lost, and the guide rail itself receives water pressure when water comes out through the inward protruding part. Ta.

[Means to solve problems]

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a tide door that can eliminate these drawbacks. A waterproof plate provided at the lower end and whose left and right edges are guided by guide rails in a loosely fitted manner, an actuating body whose tip portion is provided so as to be freely protrusive and retractable in the left and right directions from the side edges of the waterproof plate, and the actuating body. An operating tool provided on the waterproof plate to perform the appearance and retraction operation interferes with the tip of the operating body protruding from both side edges of the waterproof plate to bias the waterproof plate in either the front or back direction of the guide rail. The guide rail is characterized by being composed of a guide provided on the guide rail and a sealing material that is pressed by the bias-induced waterproof plate and seals watertightly between the inner surface of the guide rail on the bias-inducing side of the waterproof plate. It is something.

With this configuration, the present invention makes it possible to reliably press and guide the waterproof plate to the inner wall of the guide rail without using a special guide rail with a notch.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a building shutter that doubles as a tide door that is installed at the opening of a building, and the shutter 1 includes a shutter curtain 3 in which a winding drum 2 is installed, and a winding drum 2. Shutter curtain 4 and winding drum 2
The construction of the guide rail 5, etc., which guides the shutter curtain 4, which moves up and down by forward and reverse rotations, is the same as in the conventional art.

Reference numeral 6 denotes a box-shaped waterproof plate provided at the lower end of the shutter curtain 4, and the thin side edges 6a provided at both left and right ends of the waterproof plate 6 allow the guide rail 5 to fit vertically. By guiding the
It moves up and down integrally with the shutter curtain 4 to open and close the opening. Furthermore, a waterproof board storage case 7 is provided above the opening, and the waterproof board 6 is accommodated in the storage case 7 when the shutter curtain 4 is rolled up and fully opened.

On the other hand, reference numeral 8 denotes a support shaft rotatably attached to the waterproof plate 6, and a disk-shaped rotating plate 9 is integrally fixed to the support shaft 8.
One end portion of a pair of connecting rods 10 is rotatably attached to the rotary plate 9 at positions on both sides of the rotation center via pin shafts 10a, respectively. The other end of each connecting rod 10 is rotatably attached to the base end of an actuating body 11 by a pin shaft 10b. They are slidably inserted into insertion passages 12 formed in the corresponding left and right side edges 6a. The actuating body 11 is rotated at the side edge 6a by rotating the support shaft 8 in the forward and reverse directions as described later.
It is adapted to move in and out of a storage position where it is substantially flush with the edge of the side edge 6a, and an operating position where it projects from the edge of the side edge 6a.

On the other hand, a sealing material 13 is attached to one side of the inner surface (for example, the outdoor side) of the guide rail 5 at a position corresponding to the lowered waterproof plate side edge 6a, and a sealing material 13 is installed at the back of the inner surface on the opposite side. On the side, a dielectric 14 having an inclined dielectric 14a is provided. Then, when the actuating body tip 11a is made to protrude from the side edge 6a into the guide rail 5 by rotating the support shaft 8 as described above while the waterproof plate 6 is lowered, the protruding action The body tip 11a presses against and interferes with the guide surface 14a, thereby exerting a force that presses the actuating body 11 in the direction of the sealing material 13, and this pressing force causes the waterproof plate 6 to move toward the sealing material 13 side. The side edge 6
a is in close contact with the sealing material 13 in a watertight manner.

In addition, in this case, the lower end of the guide rail 5,
A second inductor 15 and an actuator 16 are provided at the lower end of the waterproof plate 6, respectively.
When the shutter curtain 4 is lowered, the fixed actuator 16 moves the inclined guide surface 15 of the second guide member 15.
By descending while sliding a, the waterproof plate 6 is set so that the lower end side is always deviated toward the sealing material 13 side and comes into contact with the sealing material 13.

Reference numeral 17 denotes an operating handle, and the operating handle 17 has its base end attached to the spindle 8 from the indoor side by keyway fitting, and the rotation of the attached operating handle 17 The above-described rotation of the support shaft 8 can be performed by operation. Moreover, 18 is a sealing material provided at the lower end of the waterproof board 6 in order to seal the waterproof board 6 and the floor surface.

In the embodiment of the present invention configured as described above, in normal times when there is no fear of water intrusion, the tip portion 1 of the actuating body
If the shutter curtain 1a is set in the retracted position recessed into the side edge 6a, the actuating body 11 and the guide body 14 are independent of each other, and therefore the shutter curtain 4 can be opened and closed in the conventional manner.

In this type of shutter curtain, when there is a risk of flooding due to heavy rain or a typhoon, the waterproof plate 6 is used to seal the curtain in a watertight manner.
As a result, the waterproof board 6 is in a slightly inclined position with its lower side brought closer to the sealing material 13. Then, in this state, the left and right connecting rods 1 are moved by operating the operating handle 17.
When the support shaft 8 is rotated so that the ends 11a of the actuator are substantially in a straight line, the actuator tip 11a is caused to protrude from the side edge 6a, and the protruding actuator tip 11a is attached to the induction body 1.
Therefore, the waterproof board 6 is forced to move toward the sealing material 13 on the opposite side to the guide 14 by the force received when the actuator 11 presses against the guide 14, and the sealing material 13 is pushed against the guide 14.
It will be fitted tightly to 3 in a watertight manner.

As described above, in the present invention, although the waterproof plate 6 is brought into close contact with the sealing material 13 in a watertight manner to prevent water from entering, the actuating body 11
is retracted into a storage position where it does not interfere with the inductor 14 under normal circumstances, and is operated to protrude only when necessary to forcibly move the waterproof plate 6 toward the sealing material 13 side.

In this way, in the embodiment of the present invention, the waterproof plate 6 is pressed against the guide rail 5 in a watertight manner,
Although it is possible to reliably prevent water from entering the room, what presses the waterproof board 6 against the guide rail 5 in a watertight manner is to use a conventional pressing tool that is swingably attached to the waterproof board. Unlike the case where the actuating body 11 is removably provided on the waterproof plate 6 and is made to protrude, unlike the case where the actuating body 11 is engaged with a notch engaging portion, the tip end portion 11a of the protruding actuating body is caused to engage with the guide body 14 provided on the guide rail 5 side. By contacting and interfering with the sealing material 13, the waterproof plate 6 is biased and guided to come into close contact with the sealing material 13, and as a result, the guide rail 5 is replaced with a conventional one with a special notch engagement part formed in the middle. There is no need to change the settings, and a general-purpose one can be used as is. Therefore, in addition to being easy to construct, the guide rail 3 itself does not require any notched engagement parts, so it can be made without any problems in terms of appearance. There is no need for things like dirt or trash to be pushed in unnecessarily and become obstructed.

Furthermore, since there is no need to ensure an engagement allowance for the pressing tool with respect to the guide rail 5, the guide rail 5 is moved inwards from the left and right edges of the opening by the engagement allowance, unlike conventional guide rails that are engaged with each other. There is no longer a need for the guide rail 5 to protrude to the side, and the guide rail 5 can be made strong by being almost embedded in the building frame.As a result, the effective width of the left and right frontage of the opening is widened, giving a rich sense of openness. In addition, the water pressure when water comes out can be directly received by the structure, and there is no need to make the guide rail itself particularly strong.

What's more, even if you have an existing shutter, you can easily convert it into a tide door by simply connecting a tide plate with a pressing tool to the bottom of the shutter curtain and using the conventional guide rail. be.

Note that this embodiment is not limited to the above-mentioned embodiment. For example, as shown in FIG. In addition, the lower end of the shutter curtain is biased toward the guide rail in advance, and the operating body is moved to the operating position when necessary to seal the shutter curtain. It is also possible to displace the actuating body to the operating position before the shutter curtain is lowered, and when the shutter curtain is lowered to its lowest position, the actuating body located at the operating position interferes with the induction body, causing the actuating body to be biased and sealed.

[Effect]

In summary, since the present invention is constructed as described above, if the actuating body is placed in the retracted position during normal times, the actuating body will not interfere with the induction body when the shutter curtain is moved up and down. Although it can move up and down smoothly like the shutter curtain of
If there is a risk of flooding, if the actuating body is projected and moved to the working position, the actuating body located at the working position will interfere with the induction body and forcibly guide the waterproof plate toward the inner surface of the guide rail, sealing it. The material is sealed in a watertight manner.

As a result, unlike the conventional method in which a press tool rotatably provided on the waterproof plate engages with the guide rail,
There is no need to make a special guide rail with a notched engagement part in the middle, and a general-purpose one can be used as is, which not only improves workability, but also improves the appearance of the guide rail itself. It becomes a problem-free product, and unlike conventional guide rails that have a notch engagement part, there is no possibility of injury by inserting a finger here, or the fact that it becomes clogged with dirt.

Furthermore, the guide rail does not need to ensure the engagement allowance for the pressing tool, so the guide rail can be almost embedded in the body. It is no longer necessary to protrude inward from the left and right edges of the opening, and the actual width of the left and right frontage of the opening is widened, creating a feeling of openness. It can be directly supported by the building frame, rather than by a guide rail, and there is no need to make the guide rail itself particularly strong.

Furthermore, even with existing shutters, it is easy to connect a waterproof plate with an actuator and an operating tool to make it appear and retract to the bottom of the shutter curtain, and also provide a guide rail and a sealing material. It also has the advantage that it can be easily renovated.
