Description

【０００１】
【発明の属する技術分野】
本発明は、エスカレータ等の乗客コンベアに備えられた移動手摺を清掃する乗客コンベアの移動手摺清掃機の支持装置に関する。
【０００２】
【従来の技術】
従来の移動手摺清掃機は、乗客コンベアの外側に取付けていた。取付け方法は、乗客コンベアの移動手摺下部平面のプレートに固定ボルト用の穴を空けて、箱型の取付台の底面にも固定ボルト用の穴を空け、箱型の取付台と乗客コンベアの移動手摺下部平面のプレートをボルト等で固定していた。
【０００３】
【発明が解決しようとする課題】
乗客コンベアの内部に移動手摺清掃機を備えることが望まれている。
【０００４】
しかしながら、移動手摺清掃機を乗客コンベアの内部構造体（支持構造体）に取付ける場合、移動手摺清掃機を固定する取付け位置は、平面ではないため、箱型の取付台をそのまま固定することができない。
【０００５】
また、乗客コンベアの機種によっては内部構造体の上下方向の寸法が異なったり、同一の機種でも移動手摺の上下方向位置には幅があり、移動手摺清掃機を取付ける場合には、上下方向が調整できるようにする必要がある。
【０００６】
さらに、移動手摺清掃機は、帯状清掃具で移動手摺を清掃しており、この帯状清掃具はある一定の周期で交換する必要があるため、移動手摺清掃機は、取付台から容易に取り外しができる構造とする必要がある。
【０００７】
本発明は、上記の問題に対処し、その目的とするところは、乗客コンベアの内部構造体（支持構造体）を利用し、移動手摺清掃機を容易に取り付け、取り外しができるものを提供せんとするものである。
【０００８】
また移動手摺清掃機の前後、左右、上下方向の位置ができ、かつ確りと固定することができるものを提供せんとするものである。
【０００９】
【課題を解決するための手段】
本発明は、乗客コンベアに備わる支持構造体に支持され、かつ移動手摺に摺接して移動手摺の清掃をする移動手摺清掃機の支持装置にあって、支持構造体は移動手摺の移動方向に沿うように延在する複数の支骨鋼材を有し、支骨鋼材に支持される載置ベースを設け、該載置ベースに移動手摺清掃機を取り外し自在に載置したことを特徴とする。
【００１０】
更に具体的には、乗客コンベアの乗客載置用移動部材と、該乗客載置用移動部材の両側に設けられ、かつ乗客載置用移動部材と一緒に移動する移動手摺と、乗客載置用移動部材および移動手摺を支持する支持構造体と、該支持構造体に支持され、かつ移動手摺に摺接して移動手摺の清掃をする移動手摺清掃機とを含む移動手摺清掃機の支持装置にあって、支持構造体は移動手摺の移動方向に沿うように延在する複数の支骨鋼材を有し、支骨鋼材に支持される載置ベースを設け、該載置ベースに移動手摺清掃機を取り外し自在に載置したことを特徴とする。
【００１１】
【発明の実施の形態】
以下、本発明の実施形態に係わる一実施例について図面に沿って説明する。
【００１２】
図１は、移動手摺清掃機１を備えた乗客コンベア２を示す。
【００１３】
乗客コンベア２は、乗客を搬送する乗客載置用移動部材と、該乗客載置用移動部材の両側に設けられ、かつ乗客載置用移動部材と一緒に移動する移動手摺３と、前記乗客載置用移動部材および前記移動手摺を支持する内部構造体４（支持構造体）とを有する。
【００１４】
移動手摺清掃機１は、乗客コンベア２の移動手摺３に摺接して清掃する。移動手摺清掃機１は、乗客コンベア２を支えるトラス等の内部構造体４（支持構造体）に後述する支持装置を用いて支持される。
【００１５】
内部構造体４（支持構造体）は、建造用の支骨鋼材（Ｌ型アングル、コの字型アングル、Ｈ型アングル等の各種鋼材）を組合せてトラス等の構造体を形成している。
【００１６】
図２は、移動手摺清掃機１の概要を示す。
【００１７】
移動手摺清掃機１は、本体ケース１０内の中央上部に清掃具押圧部１１を有する。清掃具押圧部１１は上げ下げ機構１２で上下移動の操作が行なわれる。清掃具押圧部１１は、移動手摺３の清掃時には上げられ、非清掃時には下げられる。
【００１８】
帯状清掃具１３は、未使用のところが第１のロール軸体１４に、使用済みのところが第２のロール軸体１５に巻装されている。この帯状清掃具１３は、ガイドローラ１６、清掃具押圧部１１に掛け渡されている。
【００１９】
帯状清掃具１３が清掃具押圧部１１の表面に掛けられているので、帯状清掃具１３は移動手摺３の表面を摺接して清掃することができる。帯状清掃具１３は、使用される都度、順次に第２のロール軸体１５に巻かれ、新しいところに入れ替えられるので、移動手摺３を綺麗に清掃できる。
【００２０】
第２のロール軸体１５は駆動機構１７にて駆動される。コントローラ１８は、駆動機構１７の駆動制御を行なう。また表示装置１９は移動手摺清掃機１の運転状況を表示する。
【００２１】
第１のロール軸体１４の帯状清掃具１３が全部使われると、第１のロール軸体１４および第２のロール軸体１５とともに帯状清掃具１３を移動手摺清掃機１から外し、新しい帯状清掃具と交換する。この交換作業は、移動手摺清掃機１を乗客コンベア２の据付箇所（支持装置）から外して行なう。
【００２２】
移動手摺清掃機１の本体ケース１０の後側端に設けた係合用突起２０と、前側端に設けた係合用突起２１の機能については後述する。
【００２３】
次に図３〜図３６に沿って、移動手摺清掃機を支持する支持装置および該支持装置が取り付けられる内部構造体４（支持構造体）について主に述べる。
【００２４】
内部構造体４（支持構造体）は、主に支骨鋼材を組み合わせて形成している。
【００２５】
支持構造体は、乗客載置用移動部材側に近いところに設ける手前側Ｌ型アングル３０と、乗客載置用移動部材側から離れるところに設ける奥側Ｌ型アングル３１と、手前側／奥側両Ｌ型アングル３０、３１に掛け渡すコの字型アングル３２を備えている。手前側Ｌ型アングル３０は上方に、奥側Ｌ型アングル３１は下方になるように段違いに配置される。この手前側／奥側両Ｌ型アングル３０、３１に、移動手摺清掃機１を載置する支持装置の載置ベース３３が取り付けられるのである。
【００２６】
また手前側Ｌ型アングル３０の上側に別のＬ型アングル３４が内部構造体４（支持構造体）として備わる。このＬ型アングル３４は移動手摺清掃機を支持するものではなく、エスカレータの内側壁３５を支持している。
【００２７】
奥側Ｌ型アングル３１の横向辺部３１ａの上側に支持部材としての支持台３６が支持される。支持台３６は、図１２から図１５に示すように、上部３６ａと、該上部３６ａの両側に支持足としての側部３６ｂを有する。上部３６ａは、二本の奥側接続ボルト３７が間隔を開けて設けられる。奥側接続ボルト３７は下側から差し込まれる。落下しないようにナットで上部３６ａに締め固定されている。
【００２８】
支持台３６の側部３６ｂには、フック状の金具３８がボルト／ナット等で締め付け固定される。この金具３８は、図１６、図１７に示すように前記横向辺部３１ａが嵌合する嵌合溝３８ａを有する。
【００２９】
支持台３６は、金具３８により後方移動が阻止される。また支持台３６の上側が後側に回動するような動きも阻止される。
【００３０】
また金具３８は、支持台３６の側部３６ｂに締め付け固定する前記ボルトの差込穴３８ｂが嵌合溝３８ａに沿う横穴状になっているので、奥側Ｌ型アングル３１との関係でボルト／ナットの取り付け位置を前後方向で調整移動ができる。
【００３１】
また支持台３６は下部の後側に垂下するストッパ片３６ｃを有する。このストッパ片３６ｃが奥側Ｌ型アングル３１のコーナ部後端面に当接するので、支持台３６の前側への移動は抑えられる。
【００３２】
金具３８には、差込穴３８ｂから離れている端部側に係止片３８ｃが設けられ、この係止片３８ｃが支持台３６に支持されるので、金具３８は、支持台３６に前後方向の動きが生じないように止められる。
【００３３】
支持台３６に取り付けられるクリップ状の金具３９は、図１８、図１９、図２０、図２１に示すような上側のクリップ状の金具片３９ａと、下側のクリップ状の金具片３９ｂで形成される。両金具片３９ａ、３９ｂは断面がコ字状の形状をなし、かつ金具片３９ｂにはナットが備わる。両金具片３９ａ、３９ｂに合わせ、支持台３６の上部３６ａの下面にあてがい、上部３６ａから差し込んだボルトを前記金具片３９ｂのナットに螺合することで、金具３９が支持台３６に取り付けられる。
【００３４】
これにより、金具３９には、先端から後方に向かって水平な挟み込み用の溝ができる。この溝に前記コの字型アングル３２を挟持させる。アングル３２の上側横向辺部に降端側から金具３９の溝を嵌めて挟持させるのである。この挟持により、金具３９を介して支持台３６はアングル３２に抑えられるので、支持台３６の浮き上がりが、しっかりと止められるのである。
【００３５】
載置ベース３３は、前側が手前側Ｌ型アングル３０に、奥側が奥側Ｌ型アングル３１に前述のように支持されている支持台３６に取り付けられる。
【００３６】
載置ベース３３の前側には、二本の手前側接続ボルト５０が間隔を開けて設けられる。載置ベース３３に上から挿入された手前側接続ボルト５０は載置ベース３３の置かれる高さ調整用のスペーサ５１を介してナットで締め付け固定される。このように載置ベース３３の前側には、載置ベース３３を手前側Ｌ型アングル３０に取り付ける前に備えておく。
【００３７】
前述したように奥側接続ボルト３７が、既に支持台３６に備わっているので、載置ベース３３を降ろしながら支持台３６の後側（奥側）の奥側接続ボルト３７を差し込む。これと併せて前記手前側接続ボルト５０を手前側Ｌ型アングル３０に開けた取付け穴に挿し込む。これにより、載置ベース３３は、手前側Ｌ型アングル３０と支持台３６に仮止めされる。載置ベース３３の水平をとるために、必要に応じて奥側接続ボルト３７に調整用のスペーサ５２を備える。スペーサ５１を付けないで、スペーサ５２を付けて水平を出すようにしても良い。手前側接続ボルト５０には、下側からナットを締め、奥側接続ボルト３７には上側からナットを締め付けることで、載置ベース３３はしっかり本固定される。
【００３８】
こうして取り付けられた載置ベース３３には、ここに載置する移動手摺清掃機１を着脱自在（取り外し自在）に、かつ確り締め付け固定するようにクランプや係止部（係止手段）等が備わる。
【００３９】
クランプは図２２から図３６に示すように載置ベース３３の前側に設けられる。クランプはクランプ片５３、クランプベース５４を有する。クランプ片５３は、クランプベース５４の係止穴５４ａにクランプ片５３の係合部５３ａを挿入係合する。
【００４０】
クランプ片５３の立上がり部５３ｂには、上側に係合爪５３ｃが設けられ、係合爪５３ｃから斜め上向きに延在する指掛け部５３ｄが設けられる。立上がり部５３ｂには、バネ挿入受け穴５３ｅが設けられる。
【００４１】
クランプベース５４には、一対のバネ支持部５４ｂが離して立設するように形成される。バネ支持軸５５は一対のバネ支持部５４ｂより、クランプベース５４の左右に抜けなく、かつ上側に外れないように抑えられる。
【００４２】
バネ支持軸５５に挿入支持されるつるまき状のクランプバネ５６は、背もたれ側端部はバネ挿入受け穴５３ｅに挿入して係止される。クランプバネ５６の支持足側端部は前記係合部５３ａのバネ掛け溝５３ｆに係合される。
【００４３】
このようにクランプ片５３とクランプベース５４は、バネ支持軸５５およびクランプバネ５６の取り付けで、クランプとして組み立つのである。このクランプは、載置ベース３３の前側に設けられているクランプベース支持部５７に支持される。
【００４４】
すなわち、クランプベース支持部５７にクランプベース５４の係止穴５４ａを挿入し、クランプベース支持部５７が係止穴５４ａの狭い方に移るように位置を変えることで、クランプベース５４が外れないようにクランプベース支持部５７に支持される。なお、クランプベース支持部５７を係止穴５４ａに挿入係止するのは、クランプベース５４とクランプ片５３を組み立てる前に行ない、その後でクランプ片５３を組み立てることで、クランプが抜けなくなり、脱落等が防止できる。
【００４５】
クランプベース支持部５７に支持されたクランプは、図１０および図１１に示すように回動自在に支持される。
【００４６】
載置ベース３３の後側には、係止部材６０（係止部）が備わる。この係止部材６０（係止部）は、図３、図４、図５に示すように、移動手摺清掃機１の後側を係止するものである。他方、移動手摺清掃機１の前側は、前記クランプで締め付け固定される。具体的には、移動手摺清掃機１の後端側に設けた後側の係合用突起２０（係合部）に係止部材６０（係止部）を係止させ、移動手摺清掃機１の前端側に設けた前側の係合用突起２１（係合部）をクランプで締め付け固定するものである。
【００４７】
係止部材６０（係止部）は、両端側が載置ベース３３に螺子、リベット、溶接等で止められている。係止部材６０は、移動手摺清掃機１の後端側が嵌る受け部７０を受け部７０に向けて移動手摺清掃機１を導く傾斜案内部７１を有する。受け部７０の先方には、係合用突起２０（係合部）が差し込まれる差込部７２を有する。この差込部７２は、受け部７０を後方に水平状に折り曲げた折り曲げ片７３と載置ベース３３を切起した立ち上がり部７４を有し、かつ折り曲げ片７３と立ち上がり部７４は互に係合されている。
【００４８】
移動手摺清掃機１の着脱（取り付け、取り外し）について述べる。
【００４９】
先に述べたように、移動手摺清掃機１に備えていた帯状清掃具１３を全部使うと、新しいものと交換しなければならない。
【００５０】
この交換にあたっては、図４に示すエスカレータの内側壁３５を外す。これにより、乗客載置用移動部材側から覗かれるように内部構造体４（支持構造体）の内部が現れる。内部に手を入れ、前側（向かって右側）にあるクランプを外すことで、移動手摺清掃機１の係合用突起２１（係合部）の拘束が解かれる。移動手摺清掃機１を少し前側にずらすことで、係止部材６０（係止部）から移動手摺清掃機１の係合用突起２０（係合部）が外れる。こうして、載置ベース３３から移動手摺清掃機１を取り外し、帯状清掃具１３の交換がし易いところに移して交換をすることができる。
【００５１】
帯状清掃具１３を交換した移動手摺清掃機１を載置ベース３３に載せ、移動手摺清掃機１の係合用突起２０を係止部材６０に係合し、係合用突起２１にクランプを掛けて締め付けることで、移動手摺清掃機１は載置ベース３３に確りと止められる。
【００５２】
このように移動手摺清掃機１を内部構造体４（支持構造体）の内部から取り出して帯状清掃具１３の交換ができるので、交換がし易いものである。移動手摺清掃機１の着脱（取り付け、取り外し）は、載置ベース３３に載せたり、外したりすることで行なわれるので、容易にできる。載置ベース３３への固定は、係合用突起２０と係止部材６０の係合およびクランプと係合用突起２１の締め付けによるので、確り行なわれ、固定作業ないし固定解除作業も容易に行なうことができる。
【００５３】
係合用突起２０と係止部材６０が後側（向かって左側）、クランプと係合用突起２１が前側（向かって右側）にある。言い換えると、移動手摺３の移動方向にあたる端部に位置しているので、係合用突起２０と係止部材６０の係合ないし離脱、およびクランプと係合用突起２１の掛け外しを見ながら作業ができるので作業がしやすいものである。
【００５４】
移動手摺清掃機１の係合用突起２０は、係止部材６０の差込部７２に差し込まれるように係止されるので、移動手摺清掃機１の後側は上下方向に動かぬように抑えられる。また係止部材６０の受け部７０に移動手摺清掃機１の後端側が嵌るので、移動手摺清掃機１の後端側は、水平方向に動かぬように抑えられる。さらに移動手摺清掃機１の後端側は傾斜案内部７１にガイドされて受け部７０に嵌るので、取り付けが容易に行なわれる。
【００５５】
このように移動手摺清掃機１の取り付けは、容易、かつ上下／水平方向に動かぬように確りと抑えられるのである。
【００５６】
クランプの掛け、外しについて、図１０、図１１、図３３、図３４、図３５、図３６を参照して述べる。
【００５７】
クランプ片５３には、つるまき状のクランプバネ５６で、常にＱ矢印方向押し付け力が付勢されている。移動手摺清掃機１の係合用突起２１にクランプ片５３の係合爪５３ｃが係合されたときは、そのＱ矢印方向押し付け力により、クランプ片５３の係合爪５３ｃが係合用突起２１から外れないように保持される（図３４）。
【００５８】
クランプ片５３の指掛け部５３ｄがクランプバネ５６に抗して後方に押されると、クランプ片５３は係合部５３ａと係止穴５４ａの係合点Ｐを支点として後方に回動する。この回動で、クランプ片５３の係合爪５３ｃは、係合用突起２１から外れる。クランプ片５３は、係合爪５３ｃが係合用突起２１から外れると、クランプベース５４が係止穴５４ａとクランプベース支持部５７の係合支持点を支点として回動するので、クランプは、図３５、図１１に示すように係合用突起２１から大きく離間するように置かれる。移動手摺清掃機１の取り外しに際し、クランプは支障にならない。
【００５９】
このようにクランプはクランプバネ５６の付勢により、移動手摺清掃機１を確り保持でき、移動手摺清掃機１の取り外しに際してはクランプベース５４により大きく離間するように置かれるので、その取り外し作業がし易いのである。
【００６０】
【発明の効果】
以上述べたように、本発明によれば、乗客コンベアの内部構造体（支持構造体）への移動手摺清掃機の取り付け、取り外しが容易ができるものを提供できる。
