Abstract
Description
図1は本発明の実施の形態によるエスカレーターの全景を示す構成図である。エスカレーター100は、エンドレス手摺10、機械室50、踏段51、主枠52、踏段駆動チェーン55、主軸56、駆動機57、パネル58などから構成されている。主枠52は隣接する上下階床間に架け渡されていて、エスカレーターの自重及び乗客荷重を支持する。主軸56の回転によって、複数個の踏段51が連続移動する。駆動機57は、エスカレーター100の機械室50に設けられている。駆動機57の駆動力は駆動チェーンによって主軸56に伝達される。踏段51は無端状に連結されている。主軸56の回動は踏段駆動チェーン55によって、踏段51に伝達される。エスカレーター100の乗客は昇降時にエンドレス手摺10を補助に使用する。パネル58は乗客の安全確保のために設けられている。
実施の形態2にかかわるエンドレス手摺を図14に基づいて説明する。同図は、帆布ラップ部6が金属針(ホッチキスなど)で仮固定されている様子を示す図である。実施の形態1で示したように、帆布ラップ部を接着する接着剤に熱可塑性接着剤を使用する場合、端末Aのラップ側帆布8を、端末Bの帆布凹まし部12へ挿入しても形状を保持することは困難である。そこで、耳部5の内側から飛び出ない程度の長さのホッチキス芯21で帆布ラップ部6の耳部を仮固定し、その後熱プレスにてエンドレス手摺の接続部を形成する。その結果、熱プレスでの成形後でも均一な形状に収めることができ、実施の形態1と同様、安定した接着品質を確保することができる。
あて布を使用するエンドレス構造では、帆布隙間部に集中する歪みを分散させるためと、あて布の接着面積を確保するために、あて布の長さは手摺の長さ方向が100mm以上になっている。ラップ式エンドレス構造によれば、帆布継ぎ目に隙間が発生して歪みが集中することを避けることができるため、帆布ラップ部6の長さを50mm以下にすることができる。図15は手摺曲げ剛性を測定する方法を示している。約200mmの間隔で配置した2個の支持ローラー59を使って、2点でエンドレス手摺10を支持する。万能試験機にて接続部の中心に圧子60を10mm程度押しこみ、反発力を測定する。
図17はエスカレーターの手摺駆動方式で最もよく使用されているシーブ駆動方式の概略を示している。シーブ駆動方式では、駆動シーブ62が手摺61へ駆動力を伝達する。駆動シーブ62が回転することにより、手摺61は進行方向へ押し出されるようにして進行する。手摺61が駆動シーブ62から押し出されたあと、弓状に配置されたガイドローラー63と手摺61が接触する。
