Abstract

<P>PROBLEM TO BE SOLVED: To prevent the contact of a transfer board with a floor surface in expanding and contracting a tunnel part, in a passenger boarding bridge to be laid between a terminal building and a vehicle such as an airplane or a vessel through the tunnel part or the like for a passenger getting on and off the vehicle, and to eliminate the clearance between the transfer board and the floor surface in the connection of the terminal side to the vehicle side to pass the passenger. <P>SOLUTION: The transfer board which forms an inclined surface instead of a difference in level of the floor surface is rockably set in the joint end part of a minor diameter tunnel part laid in a telescopic structure by fitting its end to the end of a major diameter tunnel part. The transfer board is connected to an actuator to rock the transfer board, whereby the position of the transfer board to the floor surface is optionally set when expanding and contracting the tunnel part and when passing the passenger after the positioning of the tunnel part. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は航空機または船舶等の交通機関に乗客が乗降するために、ターミナルビルから航空機または船舶の間に渡される旅客搭乗橋に関するものである。
【0002】
【従来の技術】
従来一般に使用されている旅客搭乗橋の概要について、図4乃至図7に基づいて説明する。
【0003】
図4は従来の旅客搭乗橋の全貌を示す概略図、図5は図4の要部構成で大径、小径のトンネル部の継ぎ目部を示す説明図、図6は図5の継ぎ目部における段差解消の工夫の一例を示す説明図、図7は他の工夫例を示す説明図である。
【0004】
旅客搭乗橋は小径のトンネル部2と、同小径のトンネル部2に対してテレスコピック構造と称される望遠鏡の伸縮部状に摺動嵌合する大径のトンネル部3とを主要構成とし、小径のトンネル部2の基端側はロタンダポスト4に支持されたロタンダ5を介してターミナルビル1に密着接続されている。
【0005】
他方、大径のトンネル部3の先端側は、地上9を可動のム−バ7に支えられ、更にその先端にはブリッジヘッド6が設けられ、同ブリッジヘッド6を介して航空機又は船舶等の乗物の乗降口に接続するようになっている。
【0006】
なお、ム−バ7は自走機能を有して前記したように地上9を移動し、小径のトンネル部2及び大径のトンネル部3をロタンダ5を軸に回転したり、大径のトンネル部3を矢印8の方向に摺動させて小径のトンネル部2と大径のトンネル部3の総合距離を伸縮させたり、また、図示省略の昇降装置により小径、大径のトンネル部2、3およびブリッジヘッド6の高さ方向で位置の調節を行う。
【0007】
ここで小径のトンネル部2及び大径のトンネル部3の長手方向の伸縮構造、すなわち小径のトンネル部2の先端が大径のトンネル部3に摺動可能に嵌まり込んだ前記テレスコピック構造の継ぎ目部を図5により説明すると、小径のトンネル部2の外周と大径のトンネル部3の内周の間には、複数のガイドローラ10が配設され、小径のトンネル部2と大径のトンネル部3が長手方向に円滑に摺動するように構成されている。
【0008】
従ってこのガイドローラ10のために、小径のトンネル部2と大径のトンネル部3の継ぎ目には、段差Hの段差部が形成されることになり、この段差部を埋めるべく小径のトンネル部2の継ぎ目端部に、同小径のトンネル部2の床面2aから大径のトンネル部3の床面3aに向かって傾斜した渡り板11を取付け、通路として階段状の段差ができないようにしている。
【0009】
【発明が解決しようとする課題】
従来の旅客搭乗橋における小径のトンネル部2と大径のトンネル部3の継ぎ目部は、前記したように複数のガイドローラ10が介装されているために、この継ぎ目部はガタや弾性変形のため両トンネル部2、3を完全に一直線上になるように支持するのは難しく、両者間には折り曲がり角θが発生する。
【0010】
更に前記両トンネル部2、3は伸縮するので、この伸縮移動を案内するガイド部(嵌合部)にかかる荷重条件が一定ではなく、同伸縮に伴って前記角度θが変動することになり、図5においてはこの角度が変わった様子を大径のトンネル部3が相対的に傾いたものとして鎖線で示している。
【0011】
このように角度θが変動すると、この継ぎ目部で渡り板11を小径のトンネル部2に固定して取付けている場合には、渡り板11の先端部(自由端)と床面3aの間の隙間δが両トンネル部2、3の伸縮と共に変わることになる。
【0012】
このような変化と相侯って両トンネル部2、3が伸縮する際に渡り板11の先端部が大径のトンネル部3の床面3aを擦ると、床面3aにはカーペット等が敷かれているから、これを傷つけることになる。
【0013】
このようなカーペット等の損傷を避けるために渡り板11の先端隙間を広くしておくと、渡り板11に人が足を引掛けて躓く原因になり、乗客が怪我をするという重大な事故へ発展することとなる。
【0014】
そこで、従来は図6に示すように、小径のトンネル部2の継ぎ目端部にヒンジ12により渡り板11を揺動可能に取付け、渡り板11の裏には滑らかに滑る滑り板14をつけて、これが床面3aに当たって滑るようにして先端部の相対的高さの差を少なくする工夫とか、あるいは図7に示すように小径のトンネル部2から支持部材16を張り出し、これに調整ボルト17をつけて渡り板11の高さを調整することが行われてきた。
【0015】
しかしながら、図6のように滑り板14を設置する対応では、滑り板14をいくら滑らかなものにしたとしても、前記滑り板14が接触している以上カーペット等の損傷はまぬがれず、また、図7の調整ボルト17による調整では、トンネル部の伸縮の都度調整する作業が伴うので面倒であり、いずれも抜本的な問題解決に至っていない状況にある。
【0016】
本発明は、このような従来の旅客搭乗橋における問題点を解消し、大径、小径の両トンネル部の伸縮時は渡り板と床面は接触せず、ターミナル側と乗物側が連絡されて人が通る時は渡り板と床面との隙間をゼロとできるようにした旅客搭乗橋を提供することを課題とするものである。
【0017】
【課題を解決するための手段】
本発明は前記した課題を解決すべくなされたもので、その第1の手段として、対向する端部を嵌め合ってテレスコピック構造とした大径のトンネル部と小径のトンネル部を伸縮してターミナル側と乗物側を連絡する旅客搭乗橋において、前記小径のトンネル部の継ぎ目端部に揺動可能に設置され、同小径のトンネル部の継ぎ目端部における大径のトンネル部の床面と小径のトンネル部の床面の間の段差部に傾斜面を形成する渡り板と、同渡り板に連絡され同渡り板を揺動するアクチュエータを設けた旅客搭乗橋を提供するものである。
【0018】
すなわち、同第1の手段によれば、大径のトンネル部とテレスコピック構造とした小径のトンネル部の継ぎ目端部に揺動可能に設置された渡り板はアクチュエータに連絡され、同アクチュエータにより揺動されるようになっているので、同アクチュエータの制御、調整により渡り板の揺動を制御、調整し、適切なタイミングで適切な揺動を行い、トンネル部の伸縮移動に際して大径のトンネル部の床面と擦りのない位置に渡り板を移動し、かつ、設置位置の微調整等煩雑な作業を不要として同渡り板の位置の設定を行い、他方、前記トンネル部の位置が決まったら前記渡り板を揺動して前記床面に対して隙間がなくなる所定位置に移動させることが出来るものである。
【0019】
また、本発明は第2の手段として、前記第1の手段において、前記アクチュエータは、前記渡り板を揺動する移動機構を介して同渡り板と連絡し、前記大径及び小径のトンネル部が伸縮するとき、前記渡り板の自由端側が大径のトンネル部の床面と離れる位置に移動し、ターミナル側と乗物側が連絡されたとき、前記床面に接触する位置に移動するように前記渡り板を揺動する旅客搭乗橋を提供するものである。
【0020】
すなわち、同第2の手段によれば、前記小径のトンネル部の継ぎ目端部に揺動可能に設置された渡り板を揺動するアクチュエータは、同渡り板を揺動する移動機構を介して渡り板と連絡しており、前記大径及び小径のトンネル部が伸縮するとき、又はターミナル側と乗物側が連絡されたときのそれぞれに応じて、前記渡り板の自由端側が大径のトンネル部の床面と離れる位置、又は隙間なく接触する位置に移動するように前記渡り板を揺動することにより、トンネル部の移動に際して渡り板による大径のトンネル部の床面の擦りはなく、また、ターミナル側と乗物側が連絡されて人が通る際には、前記渡り板と床面の間に人が躓くような隙間を形成することもなく、渡り板の位置決めを安全、適切に行うことが出来るものである。
【0021】
更にまた、本発明は第3の手段として、前記第1又は第2の手段において、前記渡り板の自由端側には、弾力を付与されて揺動可能とした可動板を設けた旅客搭乗橋を提供するものである。
【0022】
すなわち、同第3の手段によれば、前記大径及び小径のトンネル部が伸縮するとき、又はターミナル側と乗物側が連絡されたときのそれぞれに応じて、大径のトンネル部の床面と離れる位置、又は当接する位置に揺動する渡り板の自由端側には、更に可動板が弾力を付与されて揺動可能に設けられているので、ターミナル側と乗物側が連絡されて前記渡り板が前記床面と当接する位置に揺動する際に、前記渡り板は前記可動板を介して前記床面に当接し、同床面との接触をより一層安定して行うことが出来るものである。
【0023】
【発明の実施の形態】
本発明の実施の第1形態について図1及び図2に基づいて説明する。
図1は本実施の形態に係る旅客搭乗橋において、大径トンネル部と小径トンネル部の継ぎ目に設置した渡り板が、トンネルの伸縮が終わって位置決めされた状態を示す説明図、図2は前記渡り板が、トンネルの伸縮中で位置決めがなされていない状態を示す説明図である。
【0024】
なお、説明が冗長にならないように、前記した従来のものと同一の部位については、同一の符号を採用して図面中に表示し、前記従来のものの説明を援用して重複する説明を極力省略し、本実施の形態に特有の点を重点的に説明する。
【0025】
すなわち、本実施の形態において、2は小径のトンネル部、3は同小径のトンネル部2とテレスコピック構造により摺動嵌合された大径のトンネル部で、同小径のトンネル部2の床面2aの端部には、ヒンジ12で渡り板11が揺動可能に取付けられている。
【0026】
32は取付台で、同取付台32は小径のトンネル部2の床面2aの端面に固定されており、かつ、同取付台32にはエアシリンダ33が適宜のピンで枢着されている。
【0027】
また、前記小径のトンネル部2の床面2aの端部には、同床面2aの下部に、大径のトンネル部3の床面3aに沿ってこれとほぼ平行して延びる支持部材34が取付けられている。
【0028】
前記エアシリンダ33のピストンロッド33aには、2つのリンク35,36が、それぞれ一端をピン37で回転可能に連結され、リンク35の他端は渡り板11に、また、リンク36の他端は支持部材34にそれぞれピン37で揺動可能に連結されている。
【0029】
すなわち両リンク35,36は、折れ曲がり角度が変化する「くの字」状に配置され、同リンク35、36、これを支える支持部材34、ピン37等により、渡り板11をヒンジ12まわりに揺動する移動機構を構成し、また、同移動機構に力を加えるエアシリンダ33、ピストンロッド33a、その支えとなる前記取付台32等によりアクチュエータを構成している。
【0030】
なお、前記渡り板11の先端側、すなわち同渡り板11の揺動中心側となるヒンジ12と対向する自由端には、同渡り板11の幅方向に亘って鋲39等の適宜の固着具で板ばね38が取付けられ、それ自身弾力を有する可動板を構成している。
【0031】
前記のように構成された本実施の形態において、小径のトンネル部2と大径のトンネル部3が伸縮を完了し、図示省略の航空機等の乗物とターミナルビルが接続されて人が通れる状態では、エアシリンダ33のピストンロッド33aを引き込め、リンク35、36の「くの字」の折れ曲がり角度を鋭角にする。
【0032】
するとリンク35,36により渡り板11は図1に示すように下降方向に揺動し、同渡り板11の先端部に取付けられた板ばね38は、大径のトンネル部3の床面3aを押し付ける。
【0033】
なお図中で板ばね38の鎖線表示は、同板ばね38が床面3aと当接することなくフリーであればこの位置にあることを示している。
換言すれば、板ばね38はこの分弾性変形し、床面3aに対して確実、適切に当接することを示している。
【0034】
以上は小径のトンネル部2と大径のトンネル部3が伸縮を完了した状態、すなわち乗物とターミナルビルが接続されて人が通れる状態における渡り板11の状態であるが、これに対して、乗物とターミナルビルの接続のため、又は接続していたのを切り離すために、小径のトンネル部2と大径のトンネル部3を伸縮する時は、シリンダロッド33aを押し出すようにエアシリンダ33を作動する。
【0035】
すると、図2に示すようにリンク35,36の「くの字」の折れ曲がり角度は拡がって鈍角となり、「くの字」から直線に近づく方向に変位し、渡り板11は持ち上げられる方向に揺動し、板ばね38は床面3aから離れる。
【0036】
以上、乗物とターミナルビルが接続されて人が通れる状態と、同接続のため又は接続切り離しのためトンネルが伸縮する状態とに分けて説明したが、本実施の形態によれば、乗物とターミナルビルが接続されて人が通れる状態では、渡り板11の先端部は可動板の板ばね38を介して床面3aに対して完全に隙間ゼロにすることができ、ここを通る人が躓くおそれはなく、安全を確保できる。
【0037】
他方、乗物とターミナルビルの接続のため、もしくは乗物とターミナルビルの接続を切り離すためにトンネルを伸縮する時は、渡り板11の先端部は床面3aに対して接触しない位置に揺動して移動し、前記板ばね38を含めて渡り板11で床面を擦ることはないので、床面3aに敷設されたカーペット等を損傷することも無い。
【0038】
次に本発明の実施の第2形態について図3に基づいて説明する。
図3は本実施の形態に係る旅客搭乗橋において、渡り板の自由端に更に設置した可動板の概要を示す説明図である。
【0039】
なお、本実施の形態は前記実施の第1形態が渡り板11の自由端にばね板38を鋲39で止めて弾性構造のいわゆる可動板を構成していたのに対し、本実施の形態では前記ばね板38に代えて、剛体の揺動板をばね部材を介して渡り板11に接続したものであり、その余の構成は前記実施の第1形態と全く同一であるので、この変更部分のみ抜粋して図3に示し、その他の説明は省略している。
【0040】
すなわち、本実施の形態においては、渡り板11の先端部にはヒンジ部50aが設けられ、これに対応して同様のヒンジ部51aを有する揺動板51がピン52で揺動可能に取付けられて可動板を構成している。
【0041】
そして両ヒンジ部50、51aの間にはねじりばね53が装着され、同ねじりばね53の弾力により揺動板51を大径のトンネル部3の床面3aに押し付ける方向に付勢している。
【0042】
このように可動板として揺動板51を採用した本実施の形態における作用、効果は、前記実施の第1形態における板ばね38によるものと同じであるので、前記板ばね38に関連する説明を援用し、ここでの重複する説明を省略する。
【0043】
以上、本発明を図示の実施の形態について説明したが、本発明はかかる実施の形態に限定されず、本発明の範囲内でその具体的構造に種々の変更を加えてよいことはいうまでもない。
【0044】
例えば、前記各実施の形態においては、アクチュエータとしてエアシリンダを用いる例を説明したが、同アクチュエータはこれに限るものではなく、油圧であっても、また、電動ねじ等であっても良い。
【0045】
【発明の効果】
以上、本出願の請求項1に記載の発明によれば、対向する端部を嵌め合ってテレスコピック構造とした大径のトンネル部と小径のトンネル部を伸縮してターミナル側と乗物側を連絡する旅客搭乗橋において、前記小径のトンネル部の継ぎ目端部に揺動可能に設置され、同小径のトンネル部の継ぎ目端部における大径のトンネル部の床面と小径のトンネル部の床面の間の段差部に傾斜面を形成する渡り板と、同渡り板に連絡され同渡り板を揺動するアクチュエータを設けて旅客搭乗橋を構成しているので、同アクチュエータの制御、調整により渡り板の揺動を制御、調整し、適切なタイミングで適切な揺動を行い、トンネル部の伸縮移動に際して大径のトンネル部の床面と擦りのない位置に渡り板を移動し、かつ、設置位置の微調整等煩雑な作業を不要として同渡り板の位置の設定を行い、他方、前記トンネル部の位置が決まったら前記渡り板を揺動して前記床面に対して隙間がなくなる所定位置に移動させることが出来、安全性が高く、使い勝手にすぐれた好適な旅客搭乗橋を得ることが出来たものである。
【0046】
また、請求項2に記載の発明によれば、前記請求項1に記載の発明において、前記アクチュエータは、前記渡り板を揺動する移動機構を介して同渡り板と連絡し、前記大径及び小径のトンネル部が伸縮するとき、前記渡り板の自由端側が大径のトンネル部の床面と離れる位置に移動し、ターミナル側と乗物側が連絡されたとき、前記床面に接触する位置に移動するように前記渡り板を揺動するようにして旅客搭乗橋を構成しているので、前記アクチュエータにより前記移動機構を介して前記渡り板を揺動することにより、トンネル部の移動に際して渡り板による大径のトンネル部の床面の擦りはなく、また、ターミナル側と乗物側が連絡されて人が通る際には、前記渡り板と床面の間に人が躓くような隙間を形成することもなく、渡り板の位置決めを安全、適切に行うことが出来、安全性が高く、使い勝手にすぐれた好適な旅客搭乗橋を得ることが出来たものである。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a passenger boarding bridge passed between a terminal building and an aircraft or a ship so that the passenger can get on or off a transportation means such as an aircraft or a ship.
[0002]
[Prior art]
An outline of a conventional passenger boarding bridge will be described with reference to FIGS.
[0003]
FIG. 4 is a schematic view showing the entire appearance of a conventional passenger boarding bridge, FIG. 5 is an explanatory view showing a major portion of FIG. 4 showing a joint portion of a large diameter and a small diameter tunnel portion, and FIG. 6 is a step at the joint portion of FIG. FIG. 7 is an explanatory diagram showing an example of a device for solving the problem, and FIG. 7 is an explanatory diagram showing another example of the device.
[0004]
The passenger boarding bridge is mainly composed of a small-diameter tunnel portion 2 and a large-diameter tunnel portion 3 that is slidably fitted to the same small-diameter tunnel portion 2 in a telescopic structure called a telescopic structure. The base end side of the tunnel section 2 is closely connected to the terminal building 1 via a rotander 5 supported by a rotander post 4.
[0005]
On the other hand, the distal end side of the large-diameter tunnel portion 3 is supported by a movable movable member 7 on the ground 9, and a bridge head 6 is further provided at the distal end thereof. It is designed to be connected to the vehicle entrance.
[0006]
The mover 7 has a self-propelling function, moves on the ground 9 as described above, and rotates the small-diameter tunnel portion 2 and the large-diameter tunnel portion 3 around the rotunder 5, or the large-diameter tunnel. The portion 3 is slid in the direction of the arrow 8 to expand or contract the total distance between the small-diameter tunnel portion 2 and the large-diameter tunnel portion 3, or the small-diameter and large-diameter tunnel portions 2, 3 are moved by a lifting device (not shown). The position of the bridge head 6 is adjusted in the height direction.
[0007]
Here, the telescopic structure of the small-diameter tunnel portion 2 and the large-diameter tunnel portion 3 in the longitudinal direction, that is, the joint of the telescopic structure in which the tip of the small-diameter tunnel portion 2 is slidably fitted into the large-diameter tunnel portion 3. Referring to FIG. 5, a plurality of guide rollers 10 are disposed between the outer periphery of the small-diameter tunnel portion 2 and the inner periphery of the large-diameter tunnel portion 3, and the small-diameter tunnel portion 2 and the large-diameter tunnel portion are arranged. The portion 3 is configured to slide smoothly in the longitudinal direction.
[0008]
Therefore, due to the guide roller 10, a step portion having a step H is formed at the joint between the small-diameter tunnel portion 2 and the large-diameter tunnel portion 3, and the small-diameter tunnel portion 2 is filled to fill the step portion. At the end of the joint, a crossover plate 11 inclined from the floor surface 2a of the tunnel portion 2 having the same diameter to the floor surface 3a of the tunnel portion 3 having the same diameter is attached so that a step-like step is not formed as a passage.
[0009]
[Problems to be solved by the invention]
The joint between the small-diameter tunnel portion 2 and the large-diameter tunnel portion 3 in the conventional passenger boarding bridge is provided with a plurality of guide rollers 10 as described above. Therefore, it is difficult to support the two tunnel portions 2 and 3 so as to be completely on a straight line, and a bending angle θ is generated between the two.
[0010]
Further, since the tunnel portions 2 and 3 expand and contract, the load condition applied to the guide portion (fitting portion) for guiding the expansion and contraction movement is not constant, and the angle θ fluctuates with the expansion and contraction. In FIG. 5, the manner in which this angle is changed is indicated by a chain line assuming that the large-diameter tunnel portion 3 is relatively inclined.
[0011]
When the angle θ fluctuates in this manner, if the crossover plate 11 is fixedly attached to the small-diameter tunnel portion 2 at the joint portion, the gap δ between the tip end (free end) of the crossover plate 11 and the floor surface 3a. Changes with the expansion and contraction of both tunnel portions 2 and 3.
[0012]
When both ends of the tunnels 2 and 3 expand and contract in harmony with such a change, if the tip of the crossover plate 11 rubs the floor 3a of the large-diameter tunnel 3, a carpet or the like is laid on the floor 3a. That would hurt this.
[0013]
If the leading end gap of the crossover board 11 is widened in order to avoid such damage to the carpet or the like, a person may catch a foot on the crossover board 11 and trip, resulting in a serious accident that a passenger is injured. It will be.
[0014]
Conventionally, as shown in FIG. 6, a connecting plate 11 is swingably attached to a joint end of a small-diameter tunnel portion 2 by a hinge 12 and a sliding plate 14 that slides smoothly is attached to the back of the connecting plate 11, and this is To reduce the difference in the relative height of the tip by sliding on the floor 3a, or to extend the support member 16 from the small-diameter tunnel portion 2 as shown in FIG. Adjustment of the height of the crossover plate 11 has been performed.
[0015]
However, in the case where the sliding plate 14 is installed as shown in FIG. 6, no matter how smooth the sliding plate 14 is, damage to a carpet or the like cannot be prevented as long as the sliding plate 14 is in contact. The adjustment by the adjustment bolt 17 of the step 7 is troublesome because the operation of adjusting the expansion and contraction of the tunnel portion is required every time, and none of them has solved a drastic problem.
[0016]
