In addition, a restricting member 18 is provided at the front portion of the storage pit 2 to prevent the fulcrum arm 13 from rotating downward at a predetermined angle around the first horizontal pin 12.

前記扉起伏開閉装置６のレバー式扉回動付勢装置７は、図６（ａ）に示すように、幅方向に所定間隔をあけて収納ピット２の底部に開閉用ヒンジ１５が固定され、この開閉用ヒンジ１５に起伏レバー１６がその受動端寄りを幅方向の水平ピンを介して回動自在に支持されている。この起伏レバー１６は、その作動端に扉本体３ａの背面に摺動可能に当接する加圧部１６ａが突設されている。また起伏レバー１６の受動端と収納ピット２の後壁部との間に起立用コイルばね１７が連結固定されて構成されている。したがって、起立用コイルばね１７により、起伏レバー１６を起立方向に回動付勢して防水扉３を起立させることができる。
前記扉バックアップ装置８は、収納ピット２の複数箇所、たとえば両側と中央部に、前後方向に沿って配置されて上部バー２１ａと下部バー２１ｂが水平軸心周りに折畳み自在に連結されたバックアップバー２１と、下部バー２１ｂを回動する作動・解除装置２２とで構成されている。前記バックアップバー２１は、下部バー２１ｂが収納ピット２の後方の底部ヒンジ２１ｃに回動自在に連結されるとともに、上部バー２１ａが扉本体３ａの背面ヒンジ２１ｂに回動自在に連結され、図示しないストッパにより図６（ａ）に示す直線状態から右上方側への折れ曲りが規制されている。また底部ヒンジ２１ａでは、回動ピンが下部バー２１ｂに固定されており、前記作動・解除装置２２は、底部ヒンジ２１ａの回動ピンに固定された作動レバー２２ａと、作動端が作動レバー２２ａの遊端部に連結されて回動ピンを介して下部バー２１ｂを回動可能な流体圧式の作動・解除シリンダ２２ｂとで構成されている。この作動・解除シリンダ２２ｂは、伸縮駆動用の電動アクチュエータでもよいが、ここでは停電時にも使用可能な水道水圧シリンダが採用されている。したがって、防水扉３が略起立状態としてスライド扉３ｂを引き上げた後に、前記作動・解除シリンダ２２ｂを進展させることで、作動レバー２２ａを介して幾分折れ曲り状態のバックアップバー２１を直線状に回動し突っ張らせて防水扉３を支柱体４および幅方向フレーム２ａに押付け水密ゴム１９を圧縮させて止水すると同時に、この状態で防水扉３を固定して、前方から防水扉３に付加される水圧を効果的に支持することができる。また防水扉３の固定状態から開放する時に、作動・解除シリンダ２２ｂを収縮させて作動レバー２２ａを介してバックアップバー２１を折り曲げ防水扉３の固定を解除させることができる。 As shown in FIG. 6A, the lever-type door rotation urging device 7 of the door hoisting opening / closing device 6 has an opening / closing hinge 15 fixed to the bottom of the storage pit 2 at a predetermined interval in the width direction. The raising / lowering lever 16 is supported by the opening / closing hinge 15 so as to be rotatable near the passive end through a horizontal pin in the width direction. The raising / lowering lever 16 is provided with a pressing portion 16a projecting from the operating end of the raising / lowering lever 16 so as to slidably contact the back surface of the door body 3a. A standing coil spring 17 is connected and fixed between the passive end of the hoisting lever 16 and the rear wall portion of the storage pit 2. Accordingly, the waterproof door 3 can be erected by the urging coil spring 17 by turning the undulation lever 16 in the erection direction.
The door backup device 8 is arranged at a plurality of locations of the storage pit 2, for example, both sides and a central portion, along the front-rear direction, and an upper bar 21a and a lower bar 21b are connected to each other so as to be foldable around a horizontal axis. 21 and an actuating / releasing device 22 for rotating the lower bar 21b. The backup bar 21 has a lower bar 21b rotatably connected to a bottom hinge 21c behind the storage pit 2, and an upper bar 21a rotatably connected to a rear hinge 21b of the door body 3a. Bending from the linear state shown in FIG. 6A to the upper right side is restricted by the stopper. In the bottom hinge 21a, a rotation pin is fixed to the lower bar 21b. The operation / release device 22 includes an operation lever 22a fixed to the rotation pin of the bottom hinge 21a and an operation end of the operation lever 22a. It is composed of a fluid pressure type actuating / releasing cylinder 22b connected to the free end and capable of rotating the lower bar 21b via a rotating pin. The actuating / releasing cylinder 22b may be an electric actuator for expansion and contraction driving, but here, a tap water pressure cylinder that can be used even during a power failure is employed. Therefore, after the waterproof door 3 is substantially upright and the slide door 3b is pulled up, the operation / release cylinder 22b is advanced to rotate the backup bar 21 in a slightly bent state via the operation lever 22a. The waterproof door 3 is moved and stretched to press the watertight rubber 19 by pressing the waterproof door 3 against the support body 4 and the width direction frame 2a, and at the same time, the waterproof door 3 is fixed in this state, and is attached to the waterproof door 3 from the front. Can effectively support the water pressure. Further, when the waterproof door 3 is released from the fixed state, the operation / release cylinder 22b can be contracted to fold the backup bar 21 through the operation lever 22a to release the waterproof door 3.

前記扉ロック装置９は、図７に示すように、スイングロック式で、リアプレート５ｃ内に回動部材９ａを介して防水扉３側に出退自在な係止アーム９ｂが設けられており、回動具により係止アーム９ｂを防水扉３側に突出させて、起立用コイルばね１７に起立付勢された倒伏姿勢の防水扉３をロックすることができる。   As shown in FIG. 7, the door lock device 9 is a swing lock type, and is provided with a locking arm 9b that can be moved back and forth on the waterproof door 3 side through a rotating member 9a in the rear plate 5c. The locking arm 9b is projected to the waterproof door 3 side by the rotating tool, and the waterproof door 3 in the lying posture that is erected and biased to the standing coil spring 17 can be locked.

前記防水扉３には、図６（ｂ）に示すように、扉本体３ａに先端面が開放された格納部３ｃが形成されてスライド扉３ｂが出退自在に収納され、スライド扉３ｂの背面複数箇所に取りつけられた摺動ブロック３ｄを介して出退される。またスライド扉３ｂの背面中央下部にストッパ３ｅが突設されており、扉本体３ａの背面で上下位置に幅方向のガイド孔３ｆにスライド自在に装着されたストッパ受３ｇがストッパ３ｅに嵌合されてスライド扉３ｂを下限位置と上限位置にそれぞれ係止するように構成されている。   As shown in FIG. 6 (b), the waterproof door 3 is formed with a storage portion 3c having a distal end surface opened on the door main body 3a so that the slide door 3b can be retracted and retracted, and the rear surface of the slide door 3b. It is withdrawn and retracted through the sliding blocks 3d attached to a plurality of places. A stopper 3e protrudes from the lower center of the rear surface of the sliding door 3b, and a stopper receiver 3g, which is slidably mounted in the guide hole 3f in the width direction at the upper and lower positions on the rear surface of the door body 3a, is fitted to the stopper 3e. The sliding door 3b is configured to be locked at the lower limit position and the upper limit position, respectively.

上記構成において、洪水や高潮警報が発令されて防水扉装置により出入口１が閉鎖される時には、まず扉ロック装置９を解除すると、これにより起立用コイルばね１７の作用を利用して、起伏レバー１６を介して防水扉３を上方にゆっくりと回動させ起立させる。ここで、まず防水扉３が第２水平ピン１４を中心に上方に回動され、防水扉３が支点アーム１３の遊端アーム部１３ｂと直線状となって回動が規制されると、防水扉３が支点アーム１３と共に第１水平ピン１２を中心に上方に回動される。   In the above-described configuration, when a flood or storm surge warning is issued and the doorway 1 is closed by the waterproof door device, the door lock device 9 is first released, thereby utilizing the action of the coil spring 17 for raising and lowering the lever 16 Then, the waterproof door 3 is slowly rotated upward to stand. Here, first, the waterproof door 3 is pivoted upward about the second horizontal pin 14, and when the waterproof door 3 is linear with the free end arm portion 13 b of the fulcrum arm 13 and the rotation is restricted, the waterproof door 3 is waterproof. The door 3 is pivoted together with the fulcrum arm 13 about the first horizontal pin 12.

なお、起立用コイルばね１７のばね力が弱い場合には、手動により起立を補助する。この時扉バックアップ装置８は、作動・解除シリンダ２２ｂがフリー状態で、バックアップバー２１が折畳まれた状態から回動される。   When the spring force of the standing coil spring 17 is weak, the standing is assisted manually. At this time, the door backup device 8 is rotated from a state where the operation / release cylinder 22b is in a free state and the backup bar 21 is folded.

防水扉３がほぼ起立状態となると、手動で扉本体３ａからスライド扉３ｂを引き上げて、上限位置で固定する。さらに扉バックアップ装置８の作動・解除シリンダ２２ｂを進展させることで、バックアップバー２１を直線状に突っ張らせることで防水扉３をさらに前方に回動させ、支柱体４に水密ゴム１９を介して押付けて止水し防水扉３を固定する。これにより防水扉３により出入口１が閉鎖される。   When the waterproof door 3 is substantially upright, the slide door 3b is manually pulled up from the door body 3a and fixed at the upper limit position. Further, by extending the operation / release cylinder 22b of the door backup device 8, the waterproof bar 3 is further rotated forward by stretching the backup bar 21 in a straight line, and pressed against the support body 4 via the watertight rubber 19. Stop the water and fix the waterproof door 3. As a result, the doorway 1 is closed by the waterproof door 3.

警報が解除されて、出入口１を開放させる時には、扉バックアップ装置８の作動・解除シリンダ２２ｂを収縮してバックアップバー２１を少し折り曲げ、さらに手動によりスライド扉３ｂを扉本体３ａ内に押し込んで収納する。ついで、防水扉３の自重を利用して手動により、起立用コイルばね１７のばね力に抗して防水扉３を下方に倒伏させ収納ピット２に収納して、扉ロック装置９を作用させて防水扉を固定する。   When the alarm is released and the doorway 1 is opened, the operation / release cylinder 22b of the door backup device 8 is contracted, the backup bar 21 is bent slightly, and the slide door 3b is manually pushed into the door body 3a for storage. . Next, by manually utilizing the weight of the waterproof door 3, the waterproof door 3 is laid down and stored in the storage pit 2 against the spring force of the standing coil spring 17, and the door lock device 9 is operated. Secure the waterproof door.

上記実施の形態１によれば、起伏されて開閉される防水扉３を、扉本体３ａとスライド扉３ｂとで構成して、収納ピット２に収納される倒伏姿勢で、扉本体３ａ内にスライド扉３ｂを収納することで、収納ピット２の大きさを半減するとともに、起立させて出入口１を閉鎖した時には、防水扉３による止水深さを大きくとることができる。また回動起立時には、スライド扉３ｂが扉本体３ａ内に後退されるので、防水扉３の回転トルクを大幅に削減することができる。   According to the first embodiment, the waterproof door 3 that is raised and lowered and configured to be opened and closed is configured by the door body 3a and the slide door 3b, and is slid into the door body 3a in a lying posture stored in the storage pit 2. By storing the door 3b, the size of the storage pit 2 can be reduced by half, and when the doorway 1 is closed by standing up, the water stop depth by the waterproof door 3 can be increased. Further, since the sliding door 3b is retracted into the door main body 3a when turning up, the rotational torque of the waterproof door 3 can be greatly reduced.

また扉起伏開閉装置６を、起立用コイルばね１７により起伏レバー１６を介して防水扉３を起立方向に回動付勢する回動付勢装置７により構成したので、開閉時に電源装置や流体圧発生装置などの駆動源やその配線配管装置が不要となり、ランニングコストや設備コストを低減することができる。   Further, since the door hoisting opening / closing device 6 is constituted by the rotation urging device 7 that urges the waterproof door 3 in the erecting direction via the hoisting lever 16 by the standing coil spring 17, the power supply device and the fluid pressure are opened and closed. A driving source such as a generator and its wiring and piping device are not required, and running costs and equipment costs can be reduced.

バックアップバー２１を有する扉バックアップ装置８により、簡単な構造で防水扉３を支柱体４に押付けて水密性を向上させ、さらに耐水圧性能を高めて、大きい水深の水圧に対応することができる。   With the door backup device 8 having the backup bar 21, the waterproof door 3 can be pressed against the support body 4 with a simple structure to improve water tightness, further improve the water pressure resistance, and cope with water pressure at a large depth.

［実施の形態２］
実施の形態２を図９〜図１４に基いて説明する。なお、実施の形態１と同一部材には同一符号を付して説明を省略する。 [Embodiment 2]
The second embodiment will be described with reference to FIGS. The same members as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

この実施の形態２では、実施の形態１の回動付勢装置７に替えて、起伏用シリンダ装置３１を設け、扉ロック装置９を削除したものである。
すなわち、扉起伏開閉装置３０は、防水扉３を開閉駆動する複数の起伏駆動装置３１と、防水扉３を起立させて出入口１を閉鎖した状態で防水扉３を支柱体４に押付けるとともにロックしかつロック解除可能な扉バックアツプ装置８とで構成されている。 In the second embodiment, the undulating cylinder device 31 is provided in place of the rotation urging device 7 of the first embodiment, and the door lock device 9 is omitted.
That is, the door hoisting opening / closing device 30 is locked with a plurality of hoisting driving devices 31 for opening and closing the waterproof door 3 and pressing the waterproof door 3 against the support column 4 in a state where the waterproof door 3 is raised and the doorway 1 is closed. And a door back-up device 8 that can be unlocked.

前記起伏用シリンダ装置３１は、シリンダ本体３１ａの基端側が収納ピット２の底部で出入口１寄りに上下回動自在に支持され、作用端であるピストンロッド３１ｂが扉本体３ａの背面にピン連結されている。そして、防水扉３が倒伏姿勢では、起伏用シリンダ装置３１が水平姿勢から後方上方に所定角度以上で傾斜した状態で収納ピット２内に収容されている。この起伏用シリンダ装置３１の傾斜角度は、たとえば２０°前後以上に設定され、起伏用シリンダ装置３１の進展駆動力を、効果的に防水扉３の回動に変換して、第２水平ピン１４を中心に容易に回動可能に構成されている。また起伏用シリンダ装置３１は、たとえば水道水圧で駆動される水道圧シリンダが採用され、図示しないが、起動停止バルブを介して水道配管が接続されている。   In the hoisting cylinder device 31, the base end side of the cylinder body 31a is supported at the bottom of the storage pit 2 so as to be able to rotate up and down toward the entrance 1 and the piston rod 31b as the working end is pin-connected to the back surface of the door body 3a. ing. When the waterproof door 3 is in the lying down posture, the hoisting cylinder device 31 is housed in the storage pit 2 in a state where it is inclined at a predetermined angle or more from the horizontal posture to the rear upper side. The inclination angle of the hoisting cylinder device 31 is set to, for example, about 20 ° or more, and the driving force of the hoisting cylinder device 31 is effectively converted into the rotation of the waterproof door 3 so that the second horizontal pin 14 It can be easily rotated around the center. In addition, the undulation cylinder device 31 employs, for example, a water pressure cylinder driven by tap water pressure, and a water supply pipe is connected via a start / stop valve (not shown).

したがって、防水扉装置により出入口１を閉鎖する時には、起動停止バルブが操作されて起伏用シリンダ装置３１が進展され、まず防水扉３が第２水平ピン１４を中心に上方に回動され、防水扉３が遊端アーム部１３ｂと直線状となって回動が規制されると、防水扉３が支点アーム１３と共に第１水平ピン１２を中心に上方に回動されて起立される。   Therefore, when closing the doorway 1 with the waterproof door device, the start / stop valve is operated to advance the hoisting cylinder device 31. First, the waterproof door 3 is pivoted upward about the second horizontal pin 14, and the waterproof door is opened. When 3 is linear with the free end arm portion 13 b and the rotation is restricted, the waterproof door 3 is turned up together with the fulcrum arm 13 around the first horizontal pin 12 to stand.

防水扉３がほぼ起立状態となると、手動で扉本体３ａからスライド扉３ｂを引き上げて上限位置で固定する。さらに起伏用シリンダ装置３１を進展させて防水扉３をさらに前方に回動させ、支柱体４に水密ゴム１９を介して押付けて止水する。この時、バックアップバー２１が直線状に回動され、この扉バックアップ装置８により防水扉３が固定され、防水扉３により出入口１が閉鎖される。   When the waterproof door 3 is almost upright, the slide door 3b is manually pulled up from the door body 3a and fixed at the upper limit position. Further, the hoisting cylinder device 31 is advanced to rotate the waterproof door 3 further forward, and is pressed against the support body 4 via the watertight rubber 19 to stop water. At this time, the backup bar 21 is rotated linearly, the waterproof door 3 is fixed by the door backup device 8, and the doorway 1 is closed by the waterproof door 3.

警報が解除されて、出入口１を開放させる時には、扉バックアップ装置８を解除した後に、起伏用シリンダ装置３１を僅かに収縮させて防水扉３の加圧状態を解除した後、スライド扉３ｂを扉本体３ｂ内に後退させて収納し、さらに起伏用シリンダ装置３１を僅かに収縮して防水扉３を収納ピット２に収納すればよい。   When the alarm is released and the doorway 1 is opened, after the door backup device 8 is released, the hoisting cylinder device 31 is slightly contracted to release the pressurized state of the waterproof door 3, and then the slide door 3b is opened. The waterproof door 3 may be stored in the storage pit 2 by retracting and storing it in the main body 3b and further shrinking the hoisting cylinder device 31 slightly.

上記実施の形態２によれば、起伏式の防水扉３を、扉本体３ａとスライド扉３ｂとで構成して、収納ピット２に収納される倒伏姿勢で、扉本体３ａ内にスライド扉３ｂを収納することで、収納ピット２の大きさを半減するとともに、起立閉鎖時に、扉本体３ａをスライド扉３ｂから突出させることにより、出入口１の止水水深を大きくとることができる。また起立時に、扉本体３ａ内にスライド扉３ｂを収納することで、防水扉３の回転トルクを削減することができる。   According to the second embodiment, the undulating waterproof door 3 is constituted by the door main body 3a and the slide door 3b, and the sliding door 3b is placed in the door main body 3a in the lying posture stored in the storage pit 2. By storing, the size of the storage pit 2 can be reduced by half, and the water stop depth of the entrance / exit 1 can be increased by projecting the door body 3a from the slide door 3b at the time of standing and closing. In addition, the rotational torque of the waterproof door 3 can be reduced by storing the slide door 3b in the door body 3a when standing up.

また、扉支持部１０の支点アーム１２を介して防水扉３を起伏自在に支持させ、回動前半部分は、規制部材１８に下方への回動を規制された支点アーム１３の第２水平ピン１４を中心に防水扉３を上方に回動するように構成することで、起立用シリンダ装置３１と防水扉３の成す角度をできるだけ大きくなるように設定することで、回動起立初期の起立用シリンダ装置３１の駆動力を効果的に防水扉３に伝達して回動できるので、駆動力の小さい水道圧シリンダで起伏用シリンダ装置３１を構成しても、防水扉３を容易に起立させることができる。   Further, the waterproof door 3 is supported up and down via the fulcrum arm 12 of the door support portion 10, and the first half of the rotation is the second horizontal pin of the fulcrum arm 13 whose downward rotation is restricted by the restriction member 18. 14 is configured so that the waterproof door 3 is pivoted upward, so that the angle formed by the standing cylinder device 31 and the waterproof door 3 is set to be as large as possible. Since the driving force of the cylinder device 31 can be effectively transmitted to the waterproof door 3 and rotated, the waterproof door 3 can be easily erected even if the hoisting cylinder device 31 is configured with a water pressure cylinder having a small driving force. Can do.

バックアップバー２１を有する扉バックアップ装置８により、簡単な構造で防水扉３を支柱体４に押付けて水密性を向上させ、さらに耐水圧性能を高めて、大きい水深の水圧に対応することができる。   With the door backup device 8 having the backup bar 21, the waterproof door 3 can be pressed against the support body 4 with a simple structure to improve water tightness, further improve the water pressure resistance, and cope with water pressure at a large depth.

［実施の形態３］
実施の形態３を図１５〜図２１に基いて説明する。なお、実施の形態１，２と同一部材には同一符号を付して説明を省略する。 [Embodiment 3]
A third embodiment will be described with reference to FIGS. The same members as those in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

この実施の形態３における扉起伏開閉装置４０は、防水扉３を開閉駆動する複数の起立用シリンダ装置４１と、防水扉３を起立させて出入口１を閉鎖した状態で防水扉３を支柱体４に押付けるとともにロックしかつロック解除可能な扉バックアツプ装置８とで構成されている。   The door hoisting opening and closing device 40 according to the third embodiment includes a plurality of standing cylinder devices 41 that open and close the waterproof door 3, and the waterproof door 3 in a state where the waterproof door 3 is erected and the entrance 1 is closed. And a door back-up device 8 that can be pressed and locked and unlocked.

前記起立用シリンダ装置４１は、収納ピット２内に後方から出入口１側に向って配置されている。すなわち、収納ピット２内には、左右両側に所定間隔をあけて複数本の起伏用シリンダ装置（たとえば水道圧シリンダ）４１が配置され、各シリンダ本体４１ａが収納ピット２の後方部に上下回動自在に支持され、作用端であるピストンロッド４１ｂの先端が扉本体３ａの背面にピン連結されている。このように倒伏姿勢の防水扉３の固定端と離れた位置に起立用シリンダ装置４１の支持部が配置された場合、防水扉３が起立初期に大きいトルクが必要となるため、防水扉３の背面にガイド孔４３を有する連結部材４２を設けるとともに、収納ピット２にガイド体４４を設け、ピストンロッド４１ｂの先端部（作動端）にガイド孔４３にスライド自在に嵌合する連結ローラ（連結部材）４５と、ガイド体４４のガイド面４４ａに案内される起動ローラ（スライド部材）４６とが設けられている。   The cylinder device 41 for standing is arranged in the storage pit 2 from the rear toward the entrance / exit 1 side. That is, in the storage pit 2, a plurality of hoisting cylinder devices (for example, water pressure cylinders) 41 are arranged at predetermined intervals on both the left and right sides, and each cylinder body 41 a is pivoted up and down to the rear part of the storage pit 2. The tip of the piston rod 41b, which is supported freely, is pin-connected to the back surface of the door body 3a. Thus, when the support part of the cylinder device 41 for standing is arrange | positioned in the position away from the fixed end of the waterproof door 3 of a lying posture, since the waterproof door 3 requires a big torque at the initial stage of standing, A connecting member 42 having a guide hole 43 is provided on the back surface, a guide body 44 is provided in the storage pit 2, and a connecting roller (connecting member) slidably fitted into the guide hole 43 at the tip end (operating end) of the piston rod 41 b. ) 45 and an activation roller (sliding member) 46 guided by the guide surface 44a of the guide body 44 are provided.

前記連結部材４２は左右一対の板状で、各起伏用シリンダ装置４１に対応して扉本体３ａの背面に突設されており、左右の連結ローラ４５がそれぞれスライド自在に嵌合されるガイド孔４３は、図 に示すように、倒伏姿勢で、遊端側から防水扉３の前面に平行な倒伏端４３ａと、倒伏端４３ａから漸次固定端側下方に傾斜する初期起立部４３ｂと、初期起立部４３ｂから平行部４３ｃを介して漸次固定端側上方に傾斜する安定作動部４３ｄと、安定作動部４３ｄの出入口１側端の起立受動端部４３ｅとで構成されている。   The connecting member 42 is a pair of left and right plates, and protrudes from the back surface of the door body 3a corresponding to each undulating cylinder device 41, and guide holes into which the left and right connecting rollers 45 are slidably fitted. 43, as shown in the figure, in a lying posture, a lying end 43a parallel to the front surface of the waterproof door 3 from the free end side, an initial standing portion 43b that gradually slopes downward from the lying end 43a, and an initial standing position. A stable operation portion 43d that gradually inclines upward from the portion 43b via the parallel portion 43c and a standing passive end portion 43e at the end of the stable operation portion 43d at the entrance / exit 1 side.

また各起伏用シリンダ装置４１に対応して配置されたガイド体４４は、ピストンロッド４１ｂの収縮限の起動ローラ４６の当接位置から出入口１側に所定範囲で、出入口１側ほど上位となるように一定角度（図では略３５度前後）で傾斜されたガイド面４４ａが形成されている。   In addition, the guide body 44 arranged corresponding to each undulation cylinder device 41 is located in a predetermined range from the contact position of the start-up roller 46 at the contraction limit of the piston rod 41b to the entrance / exit 1 side, and is higher in the entrance / exit 1 side. A guide surface 44a inclined at a constant angle (approximately 35 degrees in the figure) is formed.

したがって、倒伏姿勢の防水扉３を回動させる時には、起伏用シリンダ４１が進展されると同時に、起動ローラ４６がガイド面４４ａに案内されて上方に転動されることで、起伏用シリンダ装置４１がシリンダ本体４１ａの支持部を中心に上方に傾動されるとともに、防水扉３が第２水平ピン１４を中心に上方に回動される。さらに連結ローラ４５が倒伏端４３ａから初期起立部４３ｂに移動することで、起立動作を早めて回動を促進させる。これにより、回動起立初期の防水扉３の動作をより効率良く行え、倒伏姿勢の防水扉３と起伏用シリンダ装置４１の成す角度が直線（１８０°）やそれに接近するような鈍角であっても、防水扉３をスムーズに起立させることができる。   Therefore, when the waterproof door 3 in the lying position is rotated, the raising / lowering cylinder 41 is advanced, and at the same time, the starting roller 46 is guided by the guide surface 44a and rolled upward, whereby the raising / lowering cylinder device 41 is moved. Is tilted upward about the support portion of the cylinder body 41a, and the waterproof door 3 is rotated upward about the second horizontal pin 14. Further, the connecting roller 45 moves from the fallen end 43a to the initial standing portion 43b, so that the standing operation is accelerated and the rotation is promoted. Thereby, the operation of the waterproof door 3 in the initial stage of turning up can be performed more efficiently, and the angle formed by the waterproof door 3 in the lying posture and the raising and lowering cylinder device 41 is a straight line (180 °) or an obtuse angle that approaches it. However, the waterproof door 3 can stand up smoothly.

上記実施の形態３によれば、起伏式の防水扉３を、扉本体３ａとスライド扉３ｂとで構成して、収納ピット２に収納される倒伏姿勢で、扉本体３ａ内にスライド扉３ｂを収納することで、収納ピット２の大きさを半減するとともに、起立閉鎖時に、扉本体３ａをスライド扉３ｂから突出させることにより、出入口１の止水水深を大きくとることができる。また起立時に、扉本体３ａ内にスライド扉３ｂを収納することで、防水扉３の回転トルクを削減することができる。   According to the third embodiment, the undulating waterproof door 3 is constituted by the door main body 3a and the slide door 3b, and the sliding door 3b is placed in the door main body 3a in the lying posture stored in the storage pit 2. By storing, the size of the storage pit 2 can be reduced by half, and the water stop depth of the entrance / exit 1 can be increased by projecting the door body 3a from the slide door 3b at the time of standing and closing. In addition, the rotational torque of the waterproof door 3 can be reduced by storing the slide door 3b in the door body 3a when standing up.

また、扉支持部１０の支点アーム１２を介して防水扉３を起伏自在に支持させ、起伏用シリンダ装置４１のピストンロッド先端部に、進展初期時にガイド体４６のガイド面４６ａに案内されて起伏用シリンダ装置４１を回動方向に傾動させる起動ローラ４６を設けるとともに、ガイド孔４３の倒伏端４３ａから傾斜された初期起立部４３ｂに移動されて、起立動作を促進させる連結ローラ４５を設けたので、起伏姿勢の防水扉３と起伏用シリンダ装置３１とが直線に近い鈍角な状態であったとしても、防水扉３をスムーズに回動起立させることができる。   Further, the waterproof door 3 is supported in a undulating manner via the fulcrum arm 12 of the door supporting unit 10 and is guided by the guide surface 46a of the guide body 46 at the initial stage of the piston rod of the urging cylinder device 41 to undulate. Since the starting roller 46 for tilting the cylinder device 41 in the rotation direction is provided, and the connecting roller 45 that is moved from the lying end 43a of the guide hole 43 to the inclined initial standing portion 43b to promote the standing motion is provided. Even if the waterproof door 3 in the undulating posture and the cylinder device 31 for undulating are in an obtuse angle state close to a straight line, the waterproof door 3 can be rotated and erected smoothly.

バックアップバー２１を有する扉バックアップ装置８により、簡単な構造で防水扉３を支柱体４に押付けて水密性を向上させ、さらに耐水圧性能を高めて、大きい水深の水圧に対応することができる。
［実施の形態４］
実施の形態４を図２２および図２３に基いて説明する。なお、実施の形態３と同一の部材には同一符号を付して説明を省略する。 With the door backup device 8 having the backup bar 21, the waterproof door 3 can be pressed against the support body 4 with a simple structure to improve water tightness, further improve the water pressure resistance, and cope with water pressure at a large depth.

すなわち、扉本体３ａの背面両側に、スライド扉３ｂを出退駆動可能な扉拡縮用シリンダ装置５１が設けられている。これにより、スライド扉３ｂの出退を扉拡縮用シリンダ装置５１により行うことができる。   That is, the door expansion / contraction cylinder device 51 capable of driving the slide door 3b to be moved in and out is provided on both sides of the back surface of the door body 3a. Thereby, the sliding door 3b can be withdrawn / retracted by the door expansion / contraction cylinder device 51.

上記実施の形態４によれば、実施の形態３と同様の作用効果を奏すことができるとともに、扉本体３ａに設けられた扉拡縮用シリンダ装置５１により、スライド扉の引上げによる防水扉３の拡大と、引き下ろしによる防水扉３の縮小を自動的に行うことができ、開閉作業による労力を削減することができる。   According to the fourth embodiment, the same effect as that of the third embodiment can be obtained, and the waterproof door 3 can be expanded by pulling up the sliding door by the door expansion / contraction cylinder device 51 provided in the door body 3a. Then, the waterproof door 3 can be automatically reduced by pulling down, and the labor required for the opening / closing operation can be reduced.
