この発明は、エスカレーター又は移動歩道であって、踏板が主枠の長手中間において乗降口寄り箇所よりも高速で移動する中間高速乗客コンベヤーの移動手摺装置に関する。
【０００２】

【発明が解決しようとする課題】
上記のように構成された従来の中間高速乗客コンベヤーの移動手摺装置では、低速移動手摺及び高速移動手摺の両者のそれぞれに対応した移動手摺の駆動機構が設けられる。このため、低速移動手摺駆動機構及び高速移動手摺駆動機構の製作及び据付のために煩雑な手数が掛かって費用が嵩むという問題点があった。また、低速移動手摺については実施設計において長さが短く、設置のためのスペースが不足することがあって低速移動手摺駆動機構の設置が困難になるという問題点があった。
【０００６】
この発明は、かかる問題点を解消するためになされたものであり、簡易な装置構成であって高速移動手摺の移動動作を伝動して低速移動手摺を駆動する中間高速乗客コンベヤーの移動手摺装置を得ることを目的とする。
【０００７】
【課題を解決するための手段】
この発明に係る中間高速乗客コンベヤーの移動手摺装置においては、主枠の幅方向における縁部に設けられてこの縁部の長手に沿って立設され上記主枠の乗降口寄りに配置された乗降口寄り欄干と、上記主枠の幅方向における縁部に設けられてこの縁部の長手に沿って立設され、上記主枠の長手中間に配置されて長手端部が上記乗降口寄り欄干の長手端部に隣接して配置され、かつ、長手方向の寸法が上記乗降口寄り欄干に比して長い中間欄干と、無端状をなし上記乗降口寄り欄干の外周に嵌合されて上記乗降口寄り欄干の長手端に湾曲した反転部を形成した低速移動手摺と、無端状をなし上記中間欄干の外周に嵌合されて上記中間欄干の長手端に湾曲した反転部を形成し、上記低速移動手摺よりも高速で移動する高速移動手摺と、上記主枠に繋がる固定部における上記中間欄干の側の位置に設けられ、上記高速移動手摺を駆動する駆動装置と、上記高速移動手摺によって摩擦駆動される摩擦駆動車、上記低速移動手摺に摩擦によって回転力を伝動する摩擦從動車、及び、上記摩擦駆動車の回転を上記摩擦從動車に減速して伝動する減速手段、からなり、上記駆動装置が生じさせた駆動力によって上記高速移動手摺と上記低速移動手摺の両方が動かされるように駆動力を伝達する伝動装置と、が設けられる。
【０００８】
【発明の実施の形態】
実施の形態１．
図１〜図３は、この発明の実施の形態の一例を示す図で、図１は移動歩道からなる乗客コンベヤーの要部側面を概念的に示す図、図２は図１の要部拡大図、図３は図２の側面の要部を拡大して示す図である。図において、乗客コンベヤーの主枠１の長手端部に乗降口２が形成され、また主枠１内に多数が連結されて循環移動する踏板３が配置される。そして、踏板３を乗降口２寄り箇所よりも主枠１の長手中間において高速駆動する駆動機構（図示しない）が設けられている。
【０００９】
また、主枠１の幅方向における縁部に乗降口寄り欄干４が設けられ、この縁部の長手に沿って立設されて主枠１の乗降口２寄りに配置される。また、主枠１の長手中間に中間欄干５が設けられて長手端部が乗降口寄り欄干４の長手端部に隣接して直列状態に配置される。また、無端状をなす低速移動手摺６が乗降口寄り欄干４の外周に嵌合されて、乗降口寄り欄干４の長手端に湾曲した反転部７を形成して配置される。
【００１０】
また、無端状をなす高速移動手摺８が中間欄干５の外周に嵌合されて中間欄干５の長手端に湾曲した反転部９を形成して配置される。そして、この反転部９が低速移動手摺６の反転部７に対して水平投影面において空隙を形成して直列に配置される。また、中間欄干５、すなわち主枠１に繋がる固定部に駆動装置１０が設けられて、主枠１の長手中間における踏板３の高速移動速度に対応した移動速度で高速移動手摺８を駆動する。
【００１１】
なお、図示が省略してあるが駆動装置１０は、高速移動手摺８の一面に接して配置された駆動輪と、高速移動手摺８の他面に配置されて高速移動手摺８を駆動輪に押圧する押圧輪とが設けられた周知の駆動機構によって構成されている。
そして、互いに対向した低速移動手摺６の反転部７と高速移動手摺８の反転部９との間に、次ぎに述べる伝動装置１１が装備される。
【００１２】
すなわち、伝動装置１１には中間欄干５に枢着されて高速移動手摺８の反転部９の内側に接して配置され高速移動手摺８によって摩擦駆動される摩擦駆動車１２及び中間欄干５に枢着されて高速移動手摺８の反転部９の外側に接して配置され高速移動手摺８を摩擦駆動車１２に押圧する押圧車１３が設けられる。
【００１３】
また、伝動装置１１には乗降口寄り欄干４に枢着されて低速移動手摺６の反転部７の内側に接して配置され低速移動手摺６に接して配置された摩擦從動車１４及び乗降口寄り欄干４に枢着されて低速移動手摺６の反転部７の外側に接して配置され低速移動手摺６を摩擦從動車１４に押圧する押圧車１５が設けられる。なお、本件において摩擦駆動車１２と摩擦從動車１４は同じ直径に形成されたものとして記述することとする。
【００１４】
また、伝動装置１１には次ぎに述べる減速手段１６が設けられる。すなわち、減速手段１６は摩擦駆動車１２の軸に固定されて摩擦駆動車１２と共に回転する鎖歯車からなる駆動車１７、摩擦從動車１４の軸に固定されて摩擦從動車１４と共に回転するた鎖歯車からなり駆動車１７よりも大径の從動車１８並びに無端状をなし駆動車１７及び從動車１８に巻掛けられたローラチェーンからなる伝動条体１９によって構成されている。また、減速手段１６は伝動条体１９等が乗降口寄り欄干４と中間欄干５の接続部における外側に配置される。
【００１５】
上記のように構成された中間高速乗客コンベヤーの移動手摺装置において、乗客コンベヤーが運転されると踏板３が乗降口２寄りにおいて踏板３が相互に接近した状態で低速移動し、主枠１の長手中間において踏板３が相互に離れた状態となり低速移動時よりも高速となって移動する。また、駆動装置１０によって高速移動手摺８が踏板３の高速移動速度に同期した移動速度で駆動される。
【００１６】
そして、高速移動手摺８の移動によって伝動装置１１の機能により低速移動手摺６が駆動される。すなわち、高速移動手摺８の移動により摩擦駆動車１２が回転し減速手段１６を介して、すなわち駆動車１７の回転が伝動条体１９によって從動車１８に伝動される。そして、從動車１８の回転による摩擦從動車１４の回転によって低速移動手摺６が駆動される。
【００１７】
これにより、駆動車１７と從動車１８の減速比によって高速移動手摺８の移動速度が減速されて、低速移動手摺６は踏板３の低速移動速度に同期した移動速度で駆動される。この構成において、低速移動手摺６のみに対応した移動手摺の駆動機構が不要になり、移動手摺駆動機構を簡易化することができて費用を低減することができる。また、低速移動手摺６の専用駆動機構が不要となるので、低速移動手摺駆動機構の設置スペースを配慮する必要がなく移動手摺装置の配設を容易化することができる。
【００１８】
なお以下、摩擦駆動車１２と摩擦從動車１４の直径は同寸法であるものとして全て記述する。そして、伝動装置１１の減速手段１６が、摩擦駆動車１２と共に回転する駆動車１７、摩擦從動車１４と共に回転する鎖歯車からなり駆動車１７よりも大径の從動車１８並びに駆動車１７及び從動車１８に巻掛けられた伝動条体１９によって構成される。このため、伝動条体１９の張力調整等の減速手段１６の保守点検作業を、乗降口寄り欄干４と中間欄干５の接続部における上方又は外側から行うことができる。したがって、減速手段１６の保守点検作業を容易化、能率化することができる。
【００１９】
なお伝動装置１１において、駆動車１７、從動車１８及び伝動条体１９を主要構成部材とする巻掛伝動機構からなる減速手段１６が、駆動車１７の回転を從動車１８に伝動する歯車伝動機構によって構成されたものであっても伝動装置１１と同様な作用を得ることができる。
【００２０】
なお、高速移動手摺８は中間高速乗客コンベヤーにおける主要構成部材であって、例えば数十メートル又はそれ以上の長大な装置となる。このため、高速移動手摺８を駆動する駆動機構は、長大装置に対して所要の駆動能力を有する機構が設けられる。これに対して、低速移動手摺６は例えば２メートル程度と短い装置であり、低速移動手摺６に作用する負荷は少ない。したがって、高速移動手摺８の移動動作によって付勢される伝動装置１１による伝動能力によって容易に低速移動手摺６を駆動することができる。
【００２１】

【００２２】

【００２４】
そして、駆動装置１０によって主枠１の長手中間における踏板３の高速移動速度に対応した移動速度で高速移動手摺８を駆動する。
また、上記双者の長手端部相互を囲むフレーム２０が設けられて、フレーム２０に摩擦駆動車１２、摩擦從動車１４、伝動条体１９、減速手段１６等の伝動装置１１の一式が装備される。
【００２５】
上記のように構成された中間高速乗客コンベヤーの移動手摺装置においても、乗客コンベヤーが運転されると踏板３が乗降口２寄りにおいて低速移動し、主枠１の長手中間において高速となって移動し、また駆動装置１０によって高速移動手摺８が踏板３の高速移動速度に同期した移動速度で駆動される。
【００２６】
そして、高速移動手摺８の移動によって減速手段１６を介して低速移動手摺６が駆動されて、踏板３の低速移動速度に同期した移動速度で駆動される。したがって、詳細な説明を省略するが図４及び図５の実施の形態においても図１〜図３の実施の形態と同様な作用が得られる。
【００２７】
また、図４及び図５の実施の形態において減速手段１６がフレーム２０に装備され、このフレーム２０が乗降口寄り欄干４及び中間欄干５の隣接部に設けられる。このため中間高速乗客コンベヤーの移動手摺装置の据付、調整、保守、点検作業が容易にでき、作業能率が向上して据付、保守等の費用を低減することができる。
【００２８】
実施の形態３．
図６及び図７も、この発明の他の実施の形態の一例を示す図で、図６はエスカレーターからなる乗客コンベヤーの要部側面を概念的に示す図であり前述の図２相当図、図７は図６の要部側面を拡大して示す図である。なお、図６及び図７の他は前述の図１〜図３と同様に中間高速乗客コンベヤーが構成されている。図において、図１〜図３と同符号は相当部分を示し、主枠１の幅方向における縁部に乗降口寄り欄干４が設けられ、この縁部の長手に沿って立設されて主枠１の乗降口２寄りに配置される。
【００２９】
また、主枠１の長手中間に中間欄干５が設けられて長手端部が乗降口寄り欄干４の長手端部に対面して配置され、水平投影面において乗降口寄り欄干４及び中間欄干５の双者の長手端部が並列に配置される。また、無端状をなす低速移動手摺６が乗降口寄り欄干４の外周に嵌合されて、乗降口寄り欄干４の長手端に湾曲した反転部７を形成して配置される。
【００３０】
また、無端状をなす高速移動手摺８が中間欄干５の外周に嵌合されて中間欄干５の長手端に湾曲した反転部９を形成して配置され、上記双者の長手端部において低速移動手摺６及び高速移動手摺８の両者が水平投影面において並列に配置される。そして、低速移動手摺６の反転部７及び高速移動手摺８の反転部９の対面箇所における下側に低速移動手摺６及び高速移動手摺８の両者の水平移動区間２２が形成される。
【００３１】
また、中間欄干５、すなわち主枠１に繋がる固定部に駆動装置１０が設けられて、主枠１の長手中間における踏板３の高速移動速度に対応した移動速度で高速移動手摺８を駆動する。そして、主枠１に繋がる固定部に次ぎに述べる伝動装置２３が設けられ、上記両者の水平移動区間２２に主枠１の長手方向に互いに離れて二組が配置される。
【００３２】
すなわち、伝動装置２３には中間欄干５に枢着されて高速移動手摺８の水平移動区間２２の内側に接して配置され高速移動手摺８によって摩擦駆動される摩擦駆動車２４及び中間欄干５に枢着されて高速移動手摺８の水平移動区間２２の外側に接して配置され高速移動手摺８を摩擦駆動車２４に押圧する押圧車２５が設けられる。

【００３５】
したがって、詳細な説明を省略するが図６及び図７の実施の形態においても図１〜図３の実施の形態と同様な作用が得られる。
また、伝動装置２３が摩擦駆動車２４及び摩擦從動車２６を主要部材として構成される。このため、構造を簡易化かつ小形化できて安価に製作することができる。また、減速手段２８の設置所要スペースが少なく狭いスペースに容易に設置することができる。
【００３６】
【発明の効果】
この発明は以上説明したように、主枠の幅方向における縁部に設けられてこの縁部の長手に沿って立設され上記主枠の乗降口寄りに配置された乗降口寄り欄干と、上記主枠の幅方向における縁部に設けられてこの縁部の長手に沿って立設され、上記主枠の長手中間に配置されて長手端部が上記乗降口寄り欄干の長手端部に隣接して配置され、かつ、長手方向の寸法が上記乗降口寄り欄干に比して長い中間欄干と、無端状をなし上記乗降口寄り欄干の外周に嵌合されて上記乗降口寄り欄干の長手端に湾曲した反転部を形成した低速移動手摺と、無端状をなし上記中間欄干の外周に嵌合されて上記中間欄干の長手端に湾曲した反転部を形成し、上記低速移動手摺よりも高速で移動する高速移動手摺と、上記主枠に繋がる固定部における上記中間欄干の側の位置に設けられ、上記高速移動手摺を駆動する駆動装置と、上記高速移動手摺によって摩擦駆動される摩擦駆動車、上記低速移動手摺に摩擦によって回転力を伝動する摩擦從動車、及び、上記摩擦駆動車の回転を上記摩擦從動車に減速して伝動する減速手段、からなり、上記駆動装置が生じさせた駆動力によって上記高速移動手摺と上記低速移動手摺の両方が動かされるように駆動力を伝達する伝動装置と、を設けたものである。
