<P>PROBLEM TO BE SOLVED: To provide an elevator car capable of normally rising and lowering even if a guide rail erected in a shaft is inclined due to earthquake or the like in a section where a base isolation device is arranged in a building. <P>SOLUTION: A car frame 8 composed of an upper frame 4, a lower frame 6, and side frames 7 is suspended and held by a main rope 9, and guide devices 10 engaged with the guide rail 2 are provided at four corners of the car frame 8. A car room 12 is arranged in the car frame 8 and is supported on the lower frame 6, and a cavity is formed in a cylindrical body 14 forming a main part of the side frame 7 to connect the upper frame 4 with the lower frame 6 by passing through a stretched bar body 15. A slide plate 19 is provided between the lower frame 6 and a lower end face of the cylindrical body 14. Since the lower frame 6 is displaced with respect to the cylindrical body 14 through the slide plate 19 by displacement of the guide devices 10 when the guide rail 2 is inclined due to earthquake in a section where the base isolation device is arranged in the building, abnormal load does not act on the car frame 8 and the occurrence of abnormality of the guide device 10 is prevented. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
この発明は、昇降路に立設されて地震時、強風時に建物の免震装置配置箇所において傾斜する案内レールに案内されるエレベーターかごに関する。
【0002】
【従来の技術】
従来のエレベーターかごにおいては、上枠、下枠及び両側の側枠がロ字状に組立てられてかご枠が構成され、エレベーターの主索によって上枠を介して吊持される。また、かご枠のロ字における四隅にそれぞれ案内具が設けられてエレベーターの昇降路に立設された案内レールに昇降自在に係合される。そして、箱状をなすかご室がかご枠内に配置されて、下部が下枠に固定された床取付金具に装着され、また上部は側枠に振止め具を介して係合される。
【0003】
従来のエレベーターかごは上記のように構成されて昇降路に配置され、かごの案内具が昇降路内に立設された案内レールに移動自在に係合される。また、かごが主索によって吊持されて、主索が巻上機(図示しない)によって駆動されることによって昇降路内を昇降するように構成されている。(例えば、特許文献1参照)。

【0005】
【発明が解決しようとする課題】
このように構成された従来のエレベーターかごを免震構造の建物に設置されるエレベーターに適用した場合に次に述べる事象が発生する。すなわち、建物において固定建築体の上に免震建築体が配置され固定建築体及び免震建築体の両者の間に免震装置が設けられる。そして、上記両者のそれぞれに設けられて互いに直列に配置された昇降路に案内レールが立設され、この案内レールにエレベーターのかごが案内具を介して案内されて昇降する。
【0006】
前述の免震構造の建物では、地震時、強風時に免震装置の配置箇所において案内レールが弾性変形して傾斜する。しかし、かごの要部をなすかご枠の剛性が高いため、案内レールの傾斜箇所においてかご枠に余計な負荷が作用し、異常荷重のために案内具に変形等の異常が発生したり、かごの昇降動作が妨げられたりするという問題点があった。
【0007】
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、昇降路に立設された案内レールが建物の免震装置配置箇所において地震等により傾斜しても、案内レールに正常に案内されて昇降するエレベーターかごを得ることを目的とする。
【0008】
【課題を解決するための手段】
この発明に係るエレベーターかごにおいては、エレベーターの案内レールが立設された昇降路に配置され、上枠、下枠及び両側の側枠がロ字状に配置されて上枠を介してエレベーターの主索によって吊持されたかご枠と、このかご枠のロ字における四隅にそれぞれ設けられて案内レールに昇降自在に係合した案内具と、箱状をなしかご枠内に配置されて下部が下枠に支持され、上部はかご枠の側枠に係合具を介して係合されたかご室と、上枠及び下枠の両者の間に配置されてかご枠における側枠の要部を構成した筒体と、この筒体内に空隙を形成して貫通して配置され両端がそれぞれ上記両者に連結されて張設された張設条体と、上記両者の一方及びこの一方に対向した筒体の端面との間に介装された低摩擦材製の摺動板とが設けられる。
【0009】
【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は一部を縦断して示す正面図、図2は図1において案内レールが傾斜した状態を示す図、図3は図2の側面図である。図において、昇降路1に案内レール2が水平方向に互いに離れて立設され、案内レール2の相互間にかご3が配置されて間口方向の両側が案内レール2と対向する。また、かご3は次ぎに述べるように構成される。
【0010】
すなわち、上枠4、緩衝器(図示しない)に対応した衝突受け板5が設けられた下枠6及び両側の側枠7がロ字状に配置されてなるかご枠8が構成される。そして、上枠4に連結されてかご3を吊持したエレベーターの主索9が設けられ、またかご枠8のロ字における四隅、すなわち上枠4及び下枠6の長手両端にそれぞれ設けられて案内レール2に昇降自在に係合したローラガイドシューからなる案内具10が配置される。
【0011】
また、床取付金具11が側枠7の下端寄りに装着されてかご枠8内の両側にそれぞれ設けられ下枠6の上に配置される。さらに、箱状をなすかご室12がかご枠8内に配置されて下部が床取付金具11に装着され、上部は側枠7に振止め具からなる係合具13を介して係合される。
【0012】
また、側枠7は次ぎに述べるように構成される。すなわち上枠4及び下枠6の両者の間に配置されて側枠7の要部を構成した筒体14、筒体14の内に空隙を形成して貫通して配置されたワイヤロープからなる張設条体15、一端が張設条体15に連結され他端は対向した上記両者の何れかに挿通されたロープシャックル16、ロープシャックル16の挿通端にねじ込まれたナット17及びロープシャックル16の挿通端に嵌合されて上記両者の何れかとナット17との間に配置された圧縮コイルばね18によって構成される。
【0013】
そして、合成樹脂板等の低摩擦材製の摺動板19がかご枠8の下枠6及び床取付金具11の間に介装される。また、斜め控え20が設けられて上端が側枠7の上端寄りに締結され、下端は床取付金具11のかご3奥行き方向における先端寄りに締結される。
【0014】
上記のように構成されたエレベーターかごにおいて、上枠4及び下枠6の両者の間に筒体14が配置されて、筒体14の内に空隙を形成して貫通して配置された張設条体15の両端がそれぞれ対向した上記両者の一つに連結されて張設される。また、かご室12はかご枠8内に配置されて下部が床取付金具11に装着されて摺動板19を介して下枠6に支持される。なお、張設条体15に作用する張力によって上枠4、下枠6、摺動板19及び床取付金具11を介して筒体14に圧縮方向の荷重が作用した状態で筒体14が上記両者間に保持される。
【0015】
そして、図1に示すようにかご3はかご枠8が直方形に配置され、通常時において張設条体15は筒体14内の中心位置に内面に触れることなく配置される。また、固定建築体とこの上に配置された免震建築体との間に免震装置が設けられた建物において、地震時等に免震装置の配置箇所において案内レール2が弾性変形して傾斜する。この場合に、傾斜した案内レール2によってかご3の下部の案内具10がかご3の間口方向に押圧されたときには、下枠6が摺動板19の摺動作用を介して床取付金具11に対して変位する。
【0016】
これによって、張設条体15は下端側が筒体14内の床取付金具11寄りに移動して図2に示す状態となる。このように、案内レール2の傾斜箇所に配置されたかご3において、下枠6が変位するので、かご枠8に余計な負荷が作用することがなく案内具10に異常が発生したり、案内レール2の傾斜箇所においてかご3の昇降動作が妨げられたりする不具合を未然に防止することができる。
【0017】
なお、両側の案内レール2を結ぶ線に直交する方向、すなわちかご3の奥行き方向への案内レール2の傾斜に対しては、傾斜した案内レール2に案内具10が押圧されることによって下枠6が摺動板19の摺動作用を介して床取付金具11に対してかご3の奥行き方向へ変位する。そして、張設条体15は筒体14内においてかご3の奥行き方向へ移動して図3に示す状態となる。
【0018】
また、前述の張設条体15を適宜な棒材からなるものとし、両端にそれぞれ設けられた雄ねじを介して前述のナット17、圧縮コイルばね18によって棒材を上枠4及び下枠6の間に張設する。このように構成されたかご枠8からなるかご3であっても、図1〜図3の実施の形態における作用を得ることができる。
【0019】
実施の形態2.
また、図1〜図3の実施の形態を応用して次ぎに述べる構成のかご3を容易に得ることができる。すなわち、前述の床取付金具11を省略してかご室12を下枠6に装着すると共に、下枠6と筒体14の下端との間に摺動板19を介装する。このような構成においても、案内レール2の傾斜箇所において下枠6が筒体14に対して摺動するので、図1〜図3の実施の形態における作用を得ることができる。
【0020】
実施の形態3.
また、図1〜図3の実施の形態を応用して次ぎに述べる構成のかご3を容易に得ることができる。すなわち、前述の床取付金具11を省略して筒体14の下部をかご室12の下部に装着すると共に、上枠4と筒体14の上端との間に摺動板19を介装する。このような構成においても、案内レール2の傾斜箇所において上枠4が筒体14に対して摺動するので、図1〜図3の実施の形態における作用を得ることができる。
【0021】
【発明の効果】
この発明は以上説明したように、エレベーターの案内レールが立設された昇降路に配置され、上枠、下枠及び両側の側枠がロ字状に配置されて上枠を介してエレベーターの主索によって吊持されたかご枠と、このかご枠のロ字における四隅にそれぞれ設けられて案内レールに昇降自在に係合した案内具と、箱状をなしかご枠内に配置されて下部が下枠に支持され、上部はかご枠の側枠に係合具を介して係合されたかご室と、上枠及び下枠の両者の間に配置されてかご枠における側枠の要部を構成した筒体と、この筒体内に空隙を形成して貫通して配置され両端がそれぞれ上記両者に連結されて張設された張設条体と、上記両者の一方及びこの一方に対向した筒体の端面との間に介装された低摩擦材製の摺動板とを設けたものである。
【0022】
これによって、上枠及び下枠の両者の間に筒体が配置されて、筒体の内に空隙を形成して貫通して配置された張設条体の両端がそれぞれ対向した上記両者の一つに連結されて張設される。また、かごはかご枠内に配置されて下部が下枠又は筒体の下部に装着される。なお、張設条体に作用する張力によって下枠、摺動板及び上枠を介して筒体に圧縮方向の荷重が作用した状態で筒体が上記両者間に保持される。
【0023】
そして、かごはかご枠が直方形に配置され、通常時において張設条体は筒体内の中心位置に内面に触れることなく配置される。また、固定建築体とこの上に配置された免震建築体との間に免震装置が設けられた建物において、地震時等に免震装置の配置箇所において案内レールが弾性変形して傾斜する。この場合に、傾斜した案内レールによってかごの上部の案内具が押圧されたときには上枠が摺動板の摺動作用を介して筒体に対して変位し、またかごの下部の案内具が押圧されたときには下枠が摺動板の摺動作用を介して筒体に対して変位する。
【0024】
これによって、張設条体は筒体内において上枠又は下枠の変位方向に移動する。このように、かごが案内レールの傾斜箇所に配置された場合に上枠又は下枠が変位するので、かご枠に余計な負荷が作用することがなく案内具に異常が発生したり、案内レールの傾斜箇所においてかごの昇降動作が妨げられたりする不具合を未然に防止する効果がある。

And a sliding plate made of a low friction material interposed between the end plate and the end surface.
[0022]
As a result, the tubular body is disposed between both the upper frame and the lower frame, and a gap is formed in the tubular body so that the two ends of the stretched bar that are penetrated and disposed are opposed to each other. They are connected and stretched. In addition, the car is arranged in the car frame, and the lower part is mounted on the lower frame or the lower part of the cylindrical body. In addition, the cylinder is held between the tensioned strip and the cylinder while a load in the compression direction is applied to the cylinder via the lower frame, the sliding plate, and the upper frame.
[0023]
In the car, the car frame is arranged in a rectangular shape, and the stretched strut is normally arranged at the center position in the cylindrical body without touching the inner surface. In addition, in a building in which a seismic isolation device is provided between a fixed building and a seismic isolation building placed on it, the guide rails are elastically deformed and inclined at the location where the seismic isolation device is placed during an earthquake or the like. . In this case, when the upper guide of the car is pressed by the inclined guide rail, the upper frame is displaced with respect to the cylinder through the sliding action of the sliding plate, and the lower guide of the car is pressed. When this is done, the lower frame is displaced with respect to the cylinder through the sliding action of the sliding plate.
