Description

本発明の実施形態は、無端状に連結した複数の踏み段を周回駆動して移動路を構成し、この移動路に対する乗降部に、乗降板を設けた乗客コンベアに関する。 The embodiment of the present invention relates to a passenger conveyor in which a plurality of endlessly connected steps are driven to circulate to form a moving path, and a boarding board is provided at a boarding portion for the moving path.

一般に、空港内建物や、デパートなどの各種の施設には、エスカレータやオートロードと呼ばれる乗客コンベアが設置されている。この乗客コンベアは、無端状に連結した複数の踏み段を周回駆動して移動路を構成している。この移動路の前方及び後方、すなわち、移動路に対する乗降部の床下には、この移動路を駆動する駆動機構等を収容するための空間がそれぞれ形成されている。 In general, passenger conveyors called escalators and autoloaders are installed in various facilities such as airport buildings and department stores. The passenger conveyor drives a plurality of steps connected endlessly to form a moving path. Spaces for accommodating a drive mechanism and the like for driving the moving path are formed in front of and behind the moving path, that is, below the floor of the getting on / off portion with respect to the moving path.

これらの空間の上面は床面に開口しており、その上面開口は通常時は板体により覆われ、移動路への乗客の乗降を可能としている。したがって、この板体は乗降板と呼ばれる。保守点検時には、この乗降板を取り外して空間内に作業員が入り、駆動機構などの保守点検作業を行う。作業終了後は、再び乗降板により上面開口を覆い、これをねじ止めして固定する。 The upper surfaces of these spaces are open to the floor surface, and the upper surface openings are normally covered with a plate so that passengers can get on and off the moving path. Therefore, this plate is called a boarding board. At the time of maintenance and inspection, the board is removed and an operator enters the space to perform maintenance and inspection work of the drive mechanism and the like. After the work is completed, the upper surface opening is covered again by the boarding board, and this is screwed and fixed.

この点検作業終了後の床下空間閉鎖時に、何らかの事情により、人が床下空間内に居ることに気付かずに乗降板を取り付け、これを外部からねじ止め固定してしまうことが考えられる。この場合、床下空間内に閉じ込めが生じることとなる。乗降板は、上述のように外部からねじ止め固定されていることから、閉じ込められた人は床下空間内から乗降板を取り外すことができず、自力で脱出できなかった。 When the underfloor space is closed after the completion of the inspection work, it is conceivable that, for some reason, the getting on / off board is attached without being aware that a person is in the underfloor space, and this is screwed and fixed from the outside. In this case, confinement occurs in the underfloor space. Since the boarding board is screwed and fixed from the outside as described above, the confined person could not remove the boarding board from the underfloor space and could not escape by himself.

このように乗降板を床下空間内から取り外すことができないため、閉じ込められた人が自力で脱出できなかった。 Since the board cannot be removed from the underfloor space, the confined person cannot escape on his own.

本発明は、乗降板を床下空間内から取り外せるようにして、床下空間からの自力での脱出を可能とした乗客コンベアを提供することにある。 An object of the present invention is to provide a passenger conveyor in which the boarding board can be detached from the underfloor space and can escape from the underfloor space by itself.

A passenger conveyor provided with a boarding board covering an opening, provided on a frame constituting the space, a base member on which an edge of the boarding board is placed, and a state where the boarding board passes through the front and back of the boarding board. Rotatably provided, and is engaged with the base member by a rotation operation from the outer surface side of the boarding / dismounting plate, and is rotated at an end in the space in a direction of releasing the engagement with the base member. And a lock mechanism having a possible release operation section.

上記構成によれば、床下の空間内から、ロック機構を解除操作することができるので、閉じ込められた人が自力で脱出することが可能となる。 According to the above configuration, the lock mechanism can be released from the space under the floor, so that the trapped person can escape by himself.

以下、本発明の実施の形態について、図面を参照して詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１及び図２は、乗客コンベアとしてエスカレータを例示した場合を示しており、以下、エスカレータを例にとって説明する。 1 and 2 show a case where an escalator is illustrated as a passenger conveyor, and the escalator will be described below as an example.

図１及び図２において、乗客コンベアの一例であるエスカレータ１０は、複数の踏み段１１を無端状に連結して、これを周回駆動することで移動路１２を構成している。この移動路１２に対する乗降部（移動路１２の進行方向前方及び後方の床面）１３には、乗降板１４が設けられている。すなわち、乗降部１３の床下には、図２で示すように、移動路１２を周回駆動するための駆動機構１６を収容する空間１７がそれぞれ形成されており、それらの上面開口は乗降板１４によって覆われている。 1 and 2, an escalator 10, which is an example of a passenger conveyor, connects a plurality of steps 11 in an endless manner and drives the circuit 11 around to form a moving path 12. A boarding / alighting board 14 is provided on the boarding / leaving portion 13 (the floor surface in front of and behind the traveling path 12) of the moving path 12. That is, as shown in FIG. 2, spaces 17 for accommodating a drive mechanism 16 for driving around the moving path 12 are respectively formed under the floor of the getting-on / off section 13, and their upper openings are formed by the getting-on / off board 14. Covered.

なお、駆動機構１６は、モータ１６１、減速機１６２などを介して回転駆動される駆動側のスプロケット１６３、この駆動側のスプロケット１６３と従動側のスプロケット１６４との間に掛け渡される駆動チェーン１６５などで構成される。そして、この駆動チェーン１６５に連結されたに複数の踏み段１１を周回駆動することで移動路１２を構成する。この駆動機構１６及びそれを収容する空間１７は建物の上下階に渡って設けられるトラス（構造フレーム）１８内に構成される。 The driving mechanism 16 includes a driving sprocket 163 that is rotatably driven via a motor 161, a speed reducer 162, and the like, a driving chain 165 bridged between the driving sprocket 163 and the driven sprocket 164, and the like. It consists of. The moving path 12 is formed by driving the plurality of steps 11 connected to the drive chain 165 to orbit. The drive mechanism 16 and the space 17 accommodating the drive mechanism 16 are configured in a truss (structural frame) 18 provided over the upper and lower floors of the building.

図３及び図４は乗降板１４の取付け構造を拡大して示している。図３及び図４において、乗降板１４は、空間１７を構成する躯体（建物の構造体又はトラス１８の一部）２１に設けられたベース部材２２上に載置される。すなわち、ベース部材２２は、空間１７内上部の上面開口に近い位置に設けられており、乗降板１４の縁部が載置されたとき、乗降板１４の上面が周囲の床面と面一となる位置関係で設けられる。 3 and 4 show the mounting structure of the boarding board 14 in an enlarged manner. 3 and 4, the boarding board 14 is placed on a base member 22 provided in a frame (a part of a building structure or a truss 18) 21 constituting the space 17. That is, the base member 22 is provided at a position close to the upper surface opening in the upper part of the space 17, and when the edge of the board 14 is placed, the upper surface of the board 14 is flush with the surrounding floor. It is provided in the following positional relationship.

乗降板１４にはロック機構２５が設けられている。このロック機構２５は、乗降板１４が空間１７の上面開口を覆った閉鎖状態でベース部材２２と係合して、乗降板１４を閉鎖状態にロックする。すなわち、ロック機構２５は、乗降板１４の表裏を貫通する状態で回転可能に設けられおり、乗降板１４の外面側からの回転操作によりその下端部に形成された係合部２５ａが、ベース部材２２に係合する。この係合部２５ａは、空間１７内に位置しており、後述するように、ベース部材２２との係合を解除する方向に回転操作可能な解除操作部としても機能する。 The board 14 is provided with a lock mechanism 25. The lock mechanism 25 engages with the base member 22 in a closed state in which the board 14 covers the upper surface opening of the space 17 and locks the board 14 in the closed state. That is, the lock mechanism 25 is rotatably provided so as to penetrate the front and back of the board 14, and the engagement portion 25 a formed at the lower end thereof by a rotation operation from the outer surface side of the board 14 is attached to the base member. 22. The engagement portion 25a is located in the space 17, and also functions as a release operation portion that can be rotated in a direction for releasing engagement with the base member 22, as described later.

具体的には、ロック機構２５は、乗降板１４の、ベース部材２２近くに形成された表裏を貫通する支持孔１４ａに、回転可能な状態で、かつ軸方向には不動な状態で支持されている。このロック機構２５の上端部には、図示しないが角型形状の操作穴（以下、角型穴と呼ぶ）が形成されており、乗降板１４の外面側から、この角型穴に角棒部を有する回転操作具２７を嵌合することで、外部からの回転操作が可能である。 Specifically, the lock mechanism 25 is supported in a rotatable state and in an axially immovable state by a support hole 14 a that penetrates the front and back surfaces of the boarding board 14 formed near the base member 22. I have. Although not shown, a square-shaped operation hole (hereinafter, referred to as a square hole) is formed at an upper end portion of the lock mechanism 25. By fitting the rotary operation tool 27 having the above, a rotary operation from outside is possible.

また、ロック機構２５の下端部、すなわち、乗降板１４の内側（空間１７内）に位置する端部には、前述した係合部２５ａが設けられている。この係合部２５ａは、図示のように水平部を有するＬ字形に形成されており、ロック機構２５が回転操作具２７により乗降板１４の外側から回転操作されることにより、水平部がベース部材２２の下面と係合し、乗降板１４を、空間１７の上面開口を覆った閉鎖状態にロックする。 The above-described engaging portion 25a is provided at a lower end portion of the lock mechanism 25, that is, an end portion located inside the boarding board 14 (in the space 17). The engaging portion 25a is formed in an L-shape having a horizontal portion as shown in the figure, and the horizontal portion is rotated from the outside of the getting on / off plate 14 by the rotation operating tool 27, so that the horizontal portion becomes a base member. The lower board 22 is engaged with the lower face, and the board 14 is locked in a closed state covering the upper opening of the space 17.

また、この係合部２５ａは、Ｌ字形であることから、空間１７内から、このＬ字形の水平部をつかんで回転操作することができる。すなわち、この回転操作によりロック機構２５の係合部２５ａをベース部材２２から外して、前述したロック状態を解除することができる。したがって、この係合部２５ａは、前述のように、ロック状態を解除する解除操作部を兼ねる。 Further, since the engaging portion 25a is L-shaped, the engaging portion 25a can be rotated from the space 17 by grasping the L-shaped horizontal portion. That is, the engaging portion 25a of the lock mechanism 25 is detached from the base member 22 by this rotation operation, and the above-described locked state can be released. Therefore, as described above, the engagement portion 25a also functions as a release operation portion for releasing the locked state.

上記構成において、乗降板１４は、図示のように、下階側及び上階側の乗降部１３に配設されており、乗客がエスカレータ１０の乗降時にその上を通行するものである。移動路１２を構成する踏み段１１は、乗客を乗せる踏み面を水平状として、一方の乗降板１４に沿ってトラス１８内から進出し、他方の乗降板１４に沿ってトラス１８内へ進入する。 In the above configuration, the boarding / alighting board 14 is disposed in the lower and upper floor side boarding and lowering sections 13 as shown in the figure, and the passenger passes above the escalator 10 when getting on and off the escalator 10. The steps 11 constituting the moving path 12 have a horizontal tread surface on which passengers are placed, advance from inside the truss 18 along one boarding board 14, and enter the truss 18 along the other boarding board 14. .

乗降板１４は、その下方のトラス１８内に在る空間（機械室）１７の出入口の蓋を兼ねており、エスカレータ１０の保守点検時は、必要に応じて取り去られ、空間（機械室）１７への出入口となる。乗降板１４を取り外す場合は、回転操作具２７の角棒部を、乗降板１４に設けられたロック機構２５の上端の角穴に嵌合させ、これを回転操作する。この回転操作により、ロック機構２５の下端のＬ字形の係合部２５ａの水平部は、ベース部材２２の下面から外れる。このため乗降板１４のロックは解除され、空間１７の上面開口を覆った状態から取り外し可能となる。 The boarding board 14 also serves as a lid for the entrance and exit of a space (machine room) 17 in a truss 18 therebelow, and is removed as necessary during maintenance and inspection of the escalator 10, and the space (machine room) It will be the entrance to 17. When removing the board 14, the square bar portion of the rotary operation tool 27 is fitted into a square hole at the upper end of the lock mechanism 25 provided on the board 14, and this is rotated. By this rotation operation, the horizontal portion of the L-shaped engaging portion 25a at the lower end of the lock mechanism 25 is disengaged from the lower surface of the base member 22. Therefore, the lock of the boarding / exiting board 14 is released, and the board can be removed from the state in which the upper surface opening of the space 17 is covered.

このようにして乗降板１４を取り外したのち、作業員は開放された上面開口から空間（機械室）１７内に入り、駆動機構１６等に対する所定の保守点検作業を実施する。作業終了後、乗降板１４を元の位置に戻して空間１７の上面開口を覆い、回転操作具２７によりロック機構２５を回転操作し、下端のＬ字形の係合部２５ａをベース部材２２の下面に係合させ、乗降板１４をロック状態とする。 After removing the boarding board 14 in this manner, the worker enters the space (machine room) 17 from the opened upper surface opening, and performs predetermined maintenance work on the drive mechanism 16 and the like. After the work is completed, the board 14 is returned to the original position to cover the upper opening of the space 17, and the lock mechanism 25 is rotated by the rotary operation tool 27, and the L-shaped engagement portion 25 a at the lower end is moved to the lower surface of the base member 22. , And the board 14 is locked.

このとき、空間１７内に人がいることに気付かずに上述のロック操作を行った場合、空間１７内の人は閉じ込め状態となる。この場合、閉じ込められた人は、空間１７内においてロック機構２５の下端のＬ字形の係合部（解除操作部）２５ａを掴み、これを回転操作する。この回転操作により係合部２５ａはベース部材２２の下面から外れ、乗降板１４のロック状態は解除される。このため、閉じ込められた人はロックが解除された乗降板１４を押し上げ、空間１７の上面開口を開放して外部に脱出することができる。 At this time, if the above-described lock operation is performed without noticing that a person is in the space 17, the person in the space 17 is in a confined state. In this case, the confined person grasps the L-shaped engagement portion (release operation portion) 25a at the lower end of the lock mechanism 25 in the space 17, and rotates this. By this rotation operation, the engaging portion 25a is disengaged from the lower surface of the base member 22, and the locked state of the getting on / off board 14 is released. Therefore, the confined person can push up the unlocked boarding / exiting board 14 to open the upper surface opening of the space 17 and escape to the outside.

このように、乗降板１４は通常時はロック機構２５により、床下の空間１７の上面開口を覆った状態にロックされ、不用意に外れたりすることはない。また万一、床下の空間１７内に人が閉じ込められた場合であっても、閉じ込められた人は空間１７内でロック機構２５の係合部（解除操作部）２５ａをつかんで回転操作することでロック状態を解除し、自力で脱出することができる。 In this manner, the board 14 is normally locked by the lock mechanism 25 so as to cover the upper opening of the space 17 under the floor, and does not accidentally come off. Even in the event that a person is trapped in the space 17 under the floor, the person trapped in the space 17 must rotate by holding the engaging portion (release operation portion) 25 a of the lock mechanism 25 in the space 17. To release the locked state and escape on its own.

なお、図４の例では、ロック機構２５を、乗降板１４の乗降方向後端部（図示左端部）に設けたが、図５で示すように、乗降板１４の左右両側部（図示上下部）にそれぞれ設けてもよい。 In the example of FIG. 4, the lock mechanism 25 is provided at the rear end (left end in the drawing) of the getting on / off board 14 as shown in FIG. 5, but as shown in FIG. ) May be provided.

次に、図６乃至図８で示す実施の形態を説明する。この実施の形態では、乗降板１４の、ベース部材２２に載置される部分に第１のねじ孔１４ｓを形成する。この第１のねじ孔１４ｓと対向するベース部材２２上に、この第１のねじ孔１４ｓと同心を成す第２のねじ孔２２ｓを形成する。 Next, the embodiment shown in FIGS. 6 to 8 will be described. In this embodiment, a first screw hole 14s is formed in a portion of the board 14 that is placed on the base member 22. On the base member 22 facing the first screw hole 14s, a second screw hole 22s concentric with the first screw hole 14s is formed.

この実施の形態に用いるロック機構３５の上端部にも、角型形状の操作穴（角型穴）が形成されており、乗降板１４の外面側から、この角型穴に角棒部を有する回転操作具２７を嵌合することで、外部からの回転操作が可能である。また、このロック機構３５の軸部外周には雄ねじ部３５ｓが形成されており、乗降板１４の外側からの回転操作により上述した第１のねじ孔１４ｓ及び第２のねじ孔２２ｓと螺合する。さらに、このロック機構３５の下端部、すなわち、乗降板１４の内側（空間１７内）に位置する端部には、Ｌ字形の解除操作部３５ａを設けている。 A square-shaped operation hole (square hole) is also formed at the upper end of the lock mechanism 35 used in this embodiment, and the square hole is provided in the square hole from the outer surface side of the boarding board 14. By fitting the rotation operation tool 27, a rotation operation from outside can be performed. A male screw portion 35s is formed on the outer periphery of the shaft portion of the lock mechanism 35, and is screwed with the first screw hole 14s and the second screw hole 22s described above by a rotation operation from the outside of the boarding / leaving plate 14. . Further, an L-shaped release operation portion 35a is provided at a lower end portion of the lock mechanism 35, that is, an end portion located inside the boarding board 14 (in the space 17).

この解除操作部３５ａは、ロック機構３５を、空間１７内から、第１のねじ孔１４ｓ及び第２のねじ孔２２ｓとの螺合を解除する方向に回転操作するためのものである。すなわち、Ｌ字形に形成された解除操作部３５ａをつまむことにより、ロック機構３５の雄ねじ部３５ｓを回転させ、上述した螺合を解除することができる。 The release operation portion 35a is for rotating the lock mechanism 35 from inside the space 17 in a direction in which the engagement with the first screw hole 14s and the second screw hole 22s is released. That is, by pinching the release operation portion 35a formed in an L-shape, the male screw portion 35s of the lock mechanism 35 is rotated, and the above-described screw engagement can be released.

なお、ロック機構３５の解除操作部３５ａは、第２のねじ孔２２ｓに螺合する雄ねじ部３５ｓの軸径より細径に形成し、Ｌ字形の部分が第１のねじ孔１４ｓ及び第２のねじ孔２２ｓを挿通できるように構成した。 Note that the release operation portion 35a of the lock mechanism 35 is formed to have a smaller diameter than the shaft diameter of the male screw portion 35s that is screwed into the second screw hole 22s, and the L-shaped portion has the first screw hole 14s and the second screw hole 22s. It was configured so that the screw hole 22s could be inserted.

上記構成において、点検作業終了後、乗降板１４は元の位置に戻され、空間１７の上面開口を覆う。この状態で回転操作具２７によりロック機構３５を回転操作し、その雄ねじ部３５ｓを第１のねじ孔１４ｓ及び第２のねじ孔２２ｓにねじ込む。この操作により、乗降板１４は、ロック機構３５によりベース部材２２に一体的にねじ止めされたロック状態となり、不用意に外れることはない。なお、このときロック機構３５の下端の解除操作部３５ａは、空間１７内に突出している。 In the above configuration, after the inspection work is completed, the boarding / alighting board 14 is returned to the original position, and covers the upper opening of the space 17. In this state, the lock mechanism 35 is rotated by the rotary operation tool 27, and the male screw portion 35s is screwed into the first screw hole 14s and the second screw hole 22s. By this operation, the boarding / alighting board 14 is in a locked state in which the board is integrally screwed to the base member 22 by the lock mechanism 35, and is not accidentally removed. At this time, the release operation portion 35 a at the lower end of the lock mechanism 35 projects into the space 17.

上述のロック操作を、空間１７内に人がいることに気付かずに行った場合、空間１７内の人は閉じ込め状態となる。この場合、閉じ込められた人は、空間１７内に突出しているロック機構３５の下端のＬ字形の解除操作部３５ａを掴み、第１のねじ孔１４ｓ及び第２のねじ孔２２ｓとの螺合を解除する方向に回転操作する。この回転操作により雄ねじ部３５ｓはベース部材２２に設けられた第２のねじ孔２２ｓから外れ、乗降板１４のロック状態は解除される。このため、閉じ込められた人はロックが解除された乗降板１４を押し上げ、空間１７の上面開口を開放して外部に脱出することができる。 When the above-described locking operation is performed without noticing that a person is in the space 17, the person in the space 17 is in a confined state. In this case, the confined person grasps the L-shaped release operation portion 35a at the lower end of the lock mechanism 35 projecting into the space 17, and engages with the first screw hole 14s and the second screw hole 22s. Rotate in the direction to release. By this rotation operation, the male screw portion 35s is disengaged from the second screw hole 22s provided in the base member 22, and the locked state of the getting on / off board 14 is released. Therefore, the confined person can push up the unlocked boarding / exiting board 14 to open the upper surface opening of the space 17 and escape to the outside.

このように、乗降板１４は通常時はロック機構３５により、床下の空間１７の上面開口を覆った状態にロックされ、不用意に外れたりすることはない。また万一、床下の空間１７内に人が閉じ込められた場合であっても、閉じ込められた人は空間１７内でロック機構３５の解除操作部３５ａをつかんで回転操作することでロック状態を解除し、自力で脱出することができる。 As described above, the board 14 is normally locked by the lock mechanism 35 so as to cover the upper opening of the space 17 under the floor, and does not accidentally come off. Even in the event that a person is trapped in the space 17 under the floor, the trapped person releases the locked state by rotating and holding the release operation unit 35a of the lock mechanism 35 in the space 17. You can escape on your own.

なお、解除操作部３５ａは、図８で示したようにＬ字形に折り曲げ加工したものを用いたが、図９で示すように、枢支部３５ａ１を設け、直線状態から、Ｌ字形に折り曲げ可能な構成としてもよい。 Note that the release operation unit 35a used was bent into an L-shape as shown in FIG. 8, but as shown in FIG. 9, a pivotal support 35a1 was provided to be able to be bent from a straight line state into an L-shape. It may be configured.

このように構成すると、解除操作部３５ａを、第１のねじ孔１４ｓ及び第２のねじ孔２２ｓに挿通させるときは直線状とし、閉じ込め脱出時は、枢支部３５ａ１を中心にＬ字形に折り曲げることにより、回転操作可能とすることができる。 With this configuration, the release operation portion 35a is linear when inserted into the first screw hole 14s and the second screw hole 22s, and is bent into an L-shape around the pivotal support portion 35a1 when confined and escaped. Thereby, the rotation operation can be performed.

また、閉じ込め時、空間１７内は無照明状態となるので、無照明状態でも目視可能なように、解除操作部３５ａに、蛍光塗料を塗布するとよい。 In addition, at the time of confinement, since the inside of the space 17 is in a non-illuminated state, it is preferable to apply a fluorescent paint to the release operation unit 35a so as to be visible even in the non-illuminated state.
