Description

本発明は、大雨や洪水時等に、建築物内，地下道内，駐車場内等の施設内に水が浸入しないように出入口を一時的に閉塞するための防水扉装置に関する。 The present invention relates to a waterproof door device for temporarily closing an entrance / exit so that water does not enter a facility such as a building, an underpass, or a parking lot during heavy rain or flood.

この種の防水扉装置は、平常時に出入口の床面や路面等の通路面下に収納しておき、大雨や洪水が発生した時に防水扉を起立させ、出入口を塞ぐようにした起上式のものがある。
防水扉の起立回動操作を駆動源にて自動操作する自動タイプと、人が起立回動させる手動タイプの２種類がある。
この起上式にあっては、防水扉が水平状態から約４５°前後まで起立させる段階での力が大きく、防水扉の裏面側を押し上げるためのバネ等による復元装置を取り付けるとともに、防水扉をこの復元力に反するように収納部にロック保持させてあり、防水扉を起立させる際にはこのロックを解除し、防水扉の起立側端部付近を持ち上げるように回動及び起立させることが行われている。
従って、この復元力が弱いと防水扉を起立させるのが大変であり、手動式にあっては持ち上げ時に大きな人の力が必要であり、自動式にあっては出力の大きな駆動源が必要となる。
逆にこの復元力が強すぎると、防水扉の水平方向収納時のはね上がり力が大きくなりすぎる技術課題があった。
本出願人は、先に扉の開閉操作の改善を目的に複数の回動アームを設け、この複数の回動アームの復元力に差を設けた技術を提案している。
これに対して本発明は、回動アームの回動軌跡及び接点の角度に着目したものである。 This type of waterproof door device is stored under the floor surface of the entrance / exit and the passage surface such as the road surface at normal times, and when the rain or flood occurs, the waterproof door is erected and the entrance is closed. There is something.
There are two types, an automatic type that automatically operates the waterproof door by a drive source, and a manual type that allows a person to stand and rotate.
In this raising type, the waterproof door has a large force at the stage of standing up to about 45 ° from the horizontal state, and a restoring device such as a spring for pushing up the back side of the waterproof door is attached and the waterproof door is attached. The storage unit is locked against the restoring force, and when the waterproof door is raised, the lock is released and the waterproof door is turned and raised so that the vicinity of the rising side end is lifted. It has been broken.
Therefore, if this restoring force is weak, it is difficult to erect the waterproof door, the manual type requires a large human force when lifting, and the automatic type requires a large output drive source. Become.
Conversely, if this restoring force is too strong, there is a technical problem that the splashing force when the waterproof door is stored in the horizontal direction becomes too large.
The present applicant has previously proposed a technique in which a plurality of rotating arms are provided for the purpose of improving the opening / closing operation of the door, and a difference is provided in the restoring force of the plurality of rotating arms.
On the other hand, the present invention pays attention to the rotation trajectory of the rotation arm and the angle of the contact.

特許第４７６１４０５号公報Japanese Patent No. 4761405

本発明は、防水扉の回動操作を容易にし、コンパクトな起上式防水扉装置の提供を目的とする。 It is an object of the present invention to provide a compact raising-type waterproof door device that facilitates the turning operation of the waterproof door.

本発明に係る起上式防水扉装置は、防水扉を出入口の通路面下に設けた収納部に概ね水平状態に収納し、当該防水扉が回動し起立状態になることで当該出入口を閉塞する起上式の防水扉装置であって、支持装置に回動可能に支持された防水扉と、防水扉の裏面側を押し上げる回動アームと、回動アームに復元力を付与する弾性復元装置とを備え、前記回動アームの先端部は防水扉の裏面に沿って上下方向に移動し、前記防水扉の裏面は前記回動アームの先端部の移動をガイドするガイド部材を有し、前記ガイド部材は前記回動アーム側に向けて円弧状に突出した円弧形状部になっていることを特徴とする。
ここで、円弧形状部は前記防水扉が概ね水平状態に収納された際に回動アームの先端部が当該防水扉の裏面に接する始点から、前記防水扉が概ね起立状態になった際に回動アームの先端部が当該防水扉の裏面に接する終点の間に亘って円弧形状になっているのが好ましい。
本発明において、弾性復元装置は駆動源を必要としない弾性手段による復元力をいい、例えばトーションバー，コイルバネ等が例として挙げられる。
コイルバネには、圧縮コイル，引張コイル等が含まれる。 The rising type waterproof door device according to the present invention stores the waterproof door in a substantially horizontal state in a storage portion provided below the passage surface of the doorway, and closes the doorway by turning the waterproof door to a standing state. The waterproof door device is a lifting type waterproof door device that is pivotally supported by the support device, a pivot arm that pushes up the back side of the waterproof door, and an elastic restoring device that imparts restoring force to the pivot arm And the tip of the pivot arm moves in the vertical direction along the back surface of the waterproof door, and the back surface of the waterproof door has a guide member that guides the movement of the tip of the pivot arm, The guide member is characterized by an arc-shaped portion protruding in an arc shape toward the rotating arm.
Here, the arc-shaped portion is rotated when the waterproof door is substantially upright from the starting point where the tip of the rotating arm contacts the back surface of the waterproof door when the waterproof door is stored in a substantially horizontal state. It is preferable that the distal end portion of the moving arm has an arc shape between the end points in contact with the back surface of the waterproof door.
In the present invention, the elastic restoring device refers to a restoring force by an elastic means that does not require a drive source, and examples thereof include a torsion bar and a coil spring.
The coil spring includes a compression coil, a tension coil, and the like.

防水扉の平坦な裏面を回動アームの先端部にて押し上げると、回動アームの起立に伴い、バネ等の復元力が防水扉の水平状態０°から起立方向４５°位までの間は急激に低下するのに対して、防水扉の起立側端部にかかる荷重変化はそれ程に低下しないので手動式の場合、人による起立回動操作が大変であった。
これに対して、本発明に係る防水扉装置にあっては、回動アームの先端部の移動軌跡をガイドするガイド部材を円弧形状にしたので、この円弧部の突出量の分だけ回動アームの戻り角度を小さく抑えることができ、その分だけ従来よりも大きな復元力となる。
これにより、起立回動操作時の人への負担が軽減されるとともに、収納時のはね上がり力を小さくすることができる。
また、自動式の場合、駆動装置を小さくできる。 When the flat rear surface of the waterproof door is pushed up at the tip of the pivot arm, the restoring force of the spring, etc., suddenly increases between the horizontal state of the waterproof door and the standing direction of 45 ° as the pivot arm rises. On the other hand, the change in load applied to the standing side end of the waterproof door does not decrease so much, so in the case of the manual type, it is difficult for the person to stand up and rotate.
On the other hand, in the waterproof door device according to the present invention, the guide member that guides the movement trajectory of the distal end portion of the rotating arm has an arc shape, so that the rotating arm corresponds to the protrusion amount of the arc portion The return angle can be kept small, and the corresponding restoring force is greater than that of the prior art.
Thereby, the burden on the person at the time of the standing and turning operation is reduced, and the splashing force at the time of storage can be reduced.
In the case of the automatic type, the drive device can be made small.

本発明に係る起上式防水扉装置の構造例を手動式にて以下図面に基づいて説明する。
本発明は、防水扉の裏面を押し上げる回動アームの移動軌跡をガイド部材で改善した点に特徴があり、この点において防水扉の他の構造に制限はなく、本実施例に限定されない。
また、駆動源を用いた自動式にも展開できる。 A structural example of the raising type waterproof door device according to the present invention will be described below manually with reference to the drawings.
The present invention is characterized in that the movement trajectory of the rotating arm that pushes up the back surface of the waterproof door is improved by the guide member. In this respect, the other structure of the waterproof door is not limited and is not limited to the present embodiment.
It can also be developed in an automatic manner using a drive source.

防水扉装置１０は、図１（ａ）に示すように平常時は出入口の通路面下に埋設された収納部１２に防水扉１１を概ね水平状態に収納してある。
防水扉１１は、起立時に下側となる部分が支持装置１５に回動可能に支持されている。
防水扉１１の裏面側を押し上げるための回動アーム１４を有し、回動アーム１４は根元側が弾性復元装置１３に連結され、回動アーム１４に防水扉１１を押し上げる復元力が作用している。 As shown in FIG. 1A, the waterproof door device 10 stores the waterproof door 11 in a substantially horizontal state in a storage portion 12 that is normally buried under the passage surface of the entrance / exit.
The waterproof door 11 is supported by the support device 15 so that the lower part of the waterproof door 11 can be rotated.
The rotating arm 14 has a rotating arm 14 for pushing up the back side of the waterproof door 11. The rotating arm 14 is connected to the elastic restoring device 13 at the base side, and a restoring force that pushes up the waterproof door 11 acts on the rotating arm 14. .

図３に収納時の防水扉を除いた状態の平面図を示す。
本実施例ではトーションコイルバネ１３ａ，１３ｂを連設し、トーションコイルバネの一端に連結した回動部材１４ｂに回動アーム１４の根元側を連結し、回動アームの先端部にローラー１４ａを回転自在に取り付けた例になっている。
また、本実施例では防水扉１１の左右２ヶ所に弾性復元装置１３及び回動アーム１４を設置した例になっているが、その数は防水扉の大きさにより設定される。
防水扉１１の裏面側には図２に示すように２枚の円弧形状板１１６，２１６を間隔ｄを隔てて取り付けてある。
これにより回動アーム１４がガイド部材１６と干渉するのを防止してある。 FIG. 3 is a plan view showing a state where the waterproof door is removed during storage.
In this embodiment, the torsion coil springs 13a and 13b are connected in series, the base side of the rotating arm 14 is connected to the rotating member 14b connected to one end of the torsion coil spring, and the roller 14a is rotatable at the tip of the rotating arm. It is an attached example.
Further, in this embodiment, the elastic restoring device 13 and the rotating arm 14 are installed at two places on the left and right sides of the waterproof door 11, but the number is set according to the size of the waterproof door.
As shown in FIG. 2, two arc-shaped plates 116 and 216 are attached to the rear surface side of the waterproof door 11 with a gap d.
This prevents the rotating arm 14 from interfering with the guide member 16.

次にガイド部材の取付位置について説明する。
図１（ａ）に示すように防水扉１１が概ね水平状態である収納時には、回動アーム１４の先端部のローラ−１４ａが円弧形状部の始点１６ａに接するようになっていて、防水扉１１が起立回動中は図１（ｂ）に示すようにローラー１４ａがガイド部材１６の円弧形状部沿って防水扉１１の根元側に向けて移動する。
防水扉１１の起立状態では図１（ｃ）に示すようにローラー１４ａは円弧形状部終点１６ｂに接するようになっている。
本実施例では起立終了時に防水扉１１がカム機構１５ａによりシール部材１７に向けて少し移動するようになっている。
このような円弧形状部は始点１６ａと終点１６ｂとの直線距離を半径とする円を描き、この円に対して前記始点１６ａと終点１６ｂとの直線距離に相当する長さが弦となる円弧部の形状として求められることができる。 Next, the mounting position of the guide member will be described.
As shown in FIG. 1A, when the waterproof door 11 is housed in a substantially horizontal state, the roller 14a at the tip of the rotating arm 14 is in contact with the starting point 16a of the arc-shaped portion. While standing up and turning, the roller 14a moves toward the base side of the waterproof door 11 along the arc-shaped portion of the guide member 16 as shown in FIG.
In the standing state of the waterproof door 11, as shown in FIG.1 (c), the roller 14a touches the circular arc shape part end point 16b.
In this embodiment, the waterproof door 11 is slightly moved toward the seal member 17 by the cam mechanism 15a at the end of standing.
Such an arc-shaped portion draws a circle whose radius is the linear distance between the starting point 16a and the ending point 16b, and an arc portion whose length corresponding to the linear distance between the starting point 16a and the ending point 16b is a chord. It can be calculated | required as a shape.

図４のグラフに防水扉１１の起立方向角度と回動アーム１４に作用する復元力の関係を示す。
Ａが本発明に係る円弧形状部からなるガイド部材１６を防水扉の裏面側に取り付けた場合で、Ｂは従来の防水扉の平坦な裏面に沿って、回動アームの先端部が移動した場合である。
Ｂは防水扉１１の立ち上げに伴って復元力が急激に低下するのに対して、Ａは特に角度１０〜４５℃の範囲にて復元力の急激な低下が抑えられていることが分かる。
また、Ｂは復元力を大きくするためにコイルバネを強くすると、収納時のはね上がり力が大きくなることも分かる。 The relationship between the standing direction angle of the waterproof door 11 and the restoring force acting on the rotating arm 14 is shown in the graph of FIG.
A is the case where the guide member 16 comprising the arc-shaped portion according to the present invention is attached to the back surface side of the waterproof door, and B is the case where the tip of the rotating arm moves along the flat back surface of the conventional waterproof door It is.
It can be seen that the restoring force of B is suddenly reduced as the waterproof door 11 is started up, whereas the rapid reduction of the restoring force is suppressed particularly in the range of an angle of 10 to 45 ° C.
It can also be seen that B increases the spring-up force during storage when the coil spring is strengthened to increase the restoring force.
