Description

【発明の属する技術分野】
本発明は、例えば美術品等を収めている搭載又は展示ケース等を、地震をはじめとする各種振動から保護するための物品搭載又は展示用の免震装置に関し、詳しくは、地震等の振動発生の際に夫々個別に直交する方向に自在に水平移動・平面移動するように水平に積層配置した各架台間に配置されて、当該移動する各架台の脱落、外脱を防止するためのストッパ機構部に改良を施した免震装置に関するものである。
【従来の技術】
従来、この種の免震装置として、本願出願人及び本発明者と同一の出願人及び発明者の開発に係る例えば特願平１１−２２１８２２号等がある。
上記免震装置は、床面等に配置する下部架台と、この下部架台の上方で美術品等を搭載又は展示する上部架台と、この下部架台と上部架台との間に配置した中間部架台とを具備し、前記下部架台、中間部架台が、地震等の振動発生の際に夫々個別に直交する方向に自在に平面移動しながら振動を吸収可能に構成し、前記上部架台上の被搭載又は展示物を地震等の各種振動から保護するようにした免震装置である。
特願平１１−２２１８２２号等のように構成した免震装置によれば、架台の平面移動により地震等の振動を吸収可能で、地震等の振動発生の際架台の平面移動により振動を吸収し架台上の被搭載又は展示物を地震等の各種振動から保護できる機能を有しながら、常時平面可動する架台の円滑な平面移動を保持し、上部架台上の被搭載又は展示物を地震等の各種振動から保護する免震装置を実現できる。
また、上記免震装置によれば、下部架台の上面と中間部架台の下面との間、中間部架台の上面と上部架の下面との間には、夫々の架台内に各転動体、例えばコロ体を装着配置しているとともに、地震等の振動発生の際に、下部架台、中間部架台とが、夫々個別に直交する前後・左右の方向に自在に振動を吸収しながら広い範囲の水平移動・平面移動が可能なように構成されて積層状態になっているので、これにより、美術品等々を搭載又は展示するようにした上部架台を支持しているその下方部分があらゆる方向に動きながら振動を吸収して上部架台上の美術品等の倒壊等を防止することができる物品搭載又は展示用の免震装置を実現できる。
更に、このような免震装置は、地震等の振動発生の際には、下部架台、中間部架台が、夫々個別に直交する前後・左右の方向に自在に振動を吸収しながら広い範囲の水平移動・平面移動可能な構成であることから、上記各架台の水平移動・平面移動する各架台が脱落・外脱しないように規制するようにしたストッパ体と相まって、下部架台、中間部架台の各水平移動・平面移動がオーバーハング状態でも安全に移動可能になるので、各架台のサイズを比較的小さくコンパクトに構成でき、本装置の設置場所も比較的狭いスペースで良く、例えば、既存、既製の搭載又は展示ケース等の内部に本装置をそのまま配置して適用しても良く、また、搭載又は展示ケース等をそのまま免震装置に載置することもできる。
【発明が解決しようとする課題】
本発明は、上述したような種類の従来の免震装置をはじめとして、地震等の振動発生の際、水平移動・平面移動するように構成した架台を具備し、この架台の水平移動・平面移動により振動を吸収可能に構成し、架台上の被搭載又は展示物を地震等の各種の振動から保護するようにした免震装置類（例えば、特願平１１−２２１８２２号の装置）における水平移動・平面移動する各架台の脱落、外脱を防止するためのストッパ機構部に改良を施した免震装置を提供するものである。
【課題を解決するための手段】
請求項１記載の免震装置は、床面に配置する下部架台と、この下部架台の上方で被搭載又は展示物を搭載又は展示する上部架台と、この下部架台と上部架台との間に配置した中間部架台とを具備し、前記下部架台、中間部架台が、地震の振動発生の際、夫々個別に直交する方向に自在に水平移動・平面移動しながら振動を吸収可能に構成し、前記上部架台上の被搭載又は展示物を地震の各種振動から保護するようにした免震装置において、前記下部架台の上面と、前記中間部架台の下面との各対向面の夫々左右位置には、夫々上下に対向配置した各レール面を有する各レール体を具備し、前記中間部架台の上面と、前記上部架台下面との各対向面の夫々左右位置には、夫々上下に対向し、且つ、前記下部架台の上面と中間部架台の下面とに配置した各レール面に直交して配置した各レール面を有する各レール体を具備し、前記下部架台の上面と中間部架台の下面との間、中間部架台の上面と上部架台下面との間には、前記各架台に配置した各レール体の上下に対向する前記各レール面に上下から挟持され、地震の振動発生の際、前記下部架台、中間部架台が夫々個別に直交する方向に自在に水平移動・平面移動可能な状態で、且つ、前記各架台に配置した各レール体の長さの範囲内においてレール面上を移動可能に構成したコロ体からなる移動体を具備し、前記夫々のレール面を有する各レール体と各移動体とをもって、レール面の長さの範囲内において、地震の振動発生のとき、前記下部架台、中間部架台の夫々個別に直交する方向への水平移動・平面移動を円滑に行うことができるとともに、前記移動した各架台の初期位置への復帰を円滑に行うことができるように構成し、前記夫々対向配置した各架台の間には、一方の架台の底面に固設されたレール形態の保持枠と、底部が前記保持枠にスライド可能に、かつ、外脱しないように嵌合していて該底部から起立して該底部に一体成形した垂直軸と、この垂直軸の左右方向に夫々Ｌ状に対向して該垂直軸に一体形成したコロ保持枠と、このコロ保持枠の各先端部分の外側に回転可能に垂直状に設置した各コロと、他方の架台側において前記各コロの下面に接近した位置で、且つ、各レール体の内側位置に沿って設けた各コロ用のコロ受面を設けたストッパ受体とを具備し、前記各架台の脱落、外脱を防止可能に構成したストッパ機構部を具備してなることを特徴とするものである。
請求項２記載の免震装置は、請求項１記載の免震装置において、前記ストッパ機構部における前記保持枠の内部に、前記垂直軸の底部を挟むような状態で前記底部のスライド方向に伸縮自在な弾性材を具備する構成としたことを特徴とするものである。
このような請求項１、２記載の各発明によれば、下部架台、中間部架台が夫々個別に直交する前後・左右の方向に自在に一層広い範囲で振動を吸収しながら水平移動・平面移動可能な構成であることから、下部架台、中間部架台の各水平移動・平面移動が一層広い範囲でのオーバーハング状態でも安全に移動可能になるので、各架台のサイズを比較的小さくコンパクトに構成できる。したがって、本装置の設置場所も比較的狭いスペースで良く、例えば、既存、既製の搭載又は展示ケース等の内部に本装置をそのまま配置して適用可能で、しかも、各移動架台の脱落、外脱を円滑に防止できるとともに、各移動架台の安定した水平移動・平面移動を確保し、さらに、初期位置への復帰可能を発揮させることができる免震装置を実現できる。
【発明の実施の形態】
以下、本発明に係る実施の形態を図面を参照して説明する。
この免震装置１は、図１の各矢印及び図２に示すように、地震等の振動発生の際、夫々個別に直交する方向に自在に水平移動・平面移動しながら振動を吸収可能に構成したものであり、床面２上に配置する下部架台１０と、この下部架台１０の上に配置する溝部２５を有する中間部架台２０と、この中間部架台２０の上に配置する溝部４２を有する上部架台４０とを具備し、上部架台４０上の被搭載物又は展示物（例えば美術品等を収めている搭載又は展示ケースＡ等）を地震等の各種振動から保護するようにした装置である。
図２中のＡは、例えば美術品等々を収めている搭載ケースであり、この免震装置１は、例えば図２に示すような状態において使用される。
図１、図２に示す各架台は、夫々対向する面が、地震等の振動発生の際、各架台が夫々個別に直交する方向に自在に水平移動・平面移動させることができるレール体５０、移動体９７を架台内に配置している。レール体５０、移動体９７の詳細については後述する。
図１中の２点鎖線の引き出し線で示す符号９０は、中間部架台２０の上方中間部架台２６と上部架台４０との間に配置した各レール体５０に直交して、当該上方中間部架台２６と上部架台４０との間に配置するストッパ機構部を構成するストッパ体を概念図として示すものである。ストッパ体９０の詳細は図３に示す通りである。
このストッパ体９０は、下部架台１０と中間部架台２０の下方中間部架台２７との間にも、各レール体５０に直交して配置している。
前記ストッパ体９０は、地震等の振動発生の際、夫々個別に直交する方向に自在に水平移動・平面移動する各架台の脱落、外脱を防止するためのもので、このストッパ体９０は、前記移動する各架台の水平移動・平面移動に沿って架台内を平面スライド可能で、且つ、前記移動した各架台の初期位置への復帰動作に沿って初期位置に復帰可能に構成している。
すなわち、本実施の形態のストッパ体９０は、図３に示すように、下部架台１０、上方中間部架台２６の各底面に固設されてストッパ体９０を架台内で平面スライド可能に構成したレール形態の保持枠７２と、底部７３が前記保持枠７２に外脱しないように嵌合していて該底部７３から起立して該底部７３に一体成形した垂直軸７４と、この垂直軸７４の左右方向に夫々Ｌ状に対向して該垂直軸に一体形成したコロ保持枠７５と、このコロ保持枠７５の各先端部分の外側に回転可能に垂直状に設置した各コロ７１と、この各コロ７１の下面に接近した位置で、且つ、各レール体５０の内側位置に沿って設けたコロ７１の受け体としての適当幅を有するレール形態の各コロ受面５３を設けたストッパ受体５４とを具備して構成している。
このように構成したストッパ体９０、ストッパ受体５４とによれば、前記各コロ７１の下面とストッパ受体５４のコロ受面５３の上面とは、地震等の振動発生の際、夫々個別に直交する方向に自在に水平移動・平面移動する前記各架台が移動可能な最大限まで至った際、前記コロ７１が回転しつつ相互に強く接合し、その結果、各移動する架台の移動は停止し、各架台の脱落、外脱を防止する。その後、前記各コロ７１の下面とストッパ受体５４のコロ受面５３の上面とは、コロ７１が回転しつつ徐々に離反しながら、前記移動した各架台は初期位置へ復帰する。
したがって、前記夫々個別に直交する方向に自在に水平移動・平面移動する前記各架台の移動の際、ストッパ体９０は、移動する各架台の水平移動・平面移動に沿って架台内を平面スライド可能で、且つ、移動した各架台の初期位置への復帰動作に沿って初期位置に復帰可能となる。
本実施の形態では、前記ストッパ体９０を、前記移動する各架台の水平移動・平面移動に沿って架台内を平面スライド可能で、且つ、前記移動した各架台の初期位置への復帰動作に沿って初期位置に復帰可能に構成しているが、本発明においては、ストッパ体９０の構成を本実施の形態に限定するものではない。
本発明においては、ストッパ機構部を構成する前記ストッパ体９０が、前記移動する各架台の水平移動・平面移動に沿って移動可能に構成されるものであれば、如何なる構成でも良く、また、このストッパ体９０自体を、架台の内部、外部、架台の如何なる位置に設置するかを問わない。
なお、本発明においては、図３中に破線で示すように、前記保持枠７２の内部に、垂直軸７４の底部７３を挟むような状態で伸縮自在な弾性材７６、例えばバネ又はダンパを具備して構成しても良い。
この場合、弾性材７６は、前記移動する各架台の水平移動・平面移動に沿って伸張するとともに、移動した各架台の移動停止後、当該弾性材７６が自ら初期位置に収縮するので、移動する各架台の水平移動・平面移動に沿って架台内を平面スライドしたストッパ体９０は、移動終了後、当該弾性材７６の自らの作用で初期位置に復帰可能となる。但し、本発明においては、前記弾性材７６は、前記移動する各架台の水平移動・平面移動に沿って伸張するように構成したものであれば十分である。
なお、前記ストッパ受体５４の各コロ受面５３は、本実施の形態のように水平に形成しても良く、また、側面からみた場合、底部を有する緩やかに傾斜した傾斜面を有するＶ字状又は円弧状として形成しても良い。
前記ストッパ受体５４の各コロ受面５３を、底部を有する緩やかに傾斜した傾斜面を有するＶ字状又は円弧状に形成して構成した場合、下部架台１０、中間部架台２０の夫々個別に直交する前後・左右の方向への自在な水平移動を一層円滑するとともに、上部架台４０の高効率な振動減衰を行うことができ、高効率に下部架台１０のレール体５０からの中間部架台２０の脱落・外脱を防止、且つ、中間部架台２０のレール体５０からの上部架台４０の脱落・外脱を防止しながら下部架台１０、中間部架台２０の各移動架台の元の位置への復帰力を一層素早くすることが可能となる。
前記ストッパ受体５４の各コロ受面５３を、底部を有する緩やかに傾斜した傾斜面を有するＶ字状又は円弧状に形成して構成した場合、下部架台１０、中間部架台２０の水平移動範囲が最大限（最大限のオーバーハング位置）の移動位置に達した時、ストッパ体９０の各コロ７１は当該コロ受面５３の傾斜面の最も高い部分に位置して移動架台（下部架台１０、中間部架台２０）が停止することになる。
次に、本実施の形態の例えばコロ体等からなる移動体９７の構成を図面を参照して説明する。
本実施の形態の移動体９７は、前記のような免震装置１における下部架台１０の上面と前記中間部架台２０の下面との各対向面の夫々左右位置に、夫々上下に対向するようにして配置される各レール面５１の間に配置されるとともに、前記中間部架台２０の上面と前記上部架台４０の下面との各対向面の夫々左右位置に、夫々上下に対向するようにして配置され、且つ、前記下部架台１０の上面と中間部架台２０の下面とに配置した各レール面５１に直交するようにして配置される各レール面５１の間に配置される。
なお、本実施の形態においては、前記各架台の上下面に夫々対向配置する各レール体５０が、夫々凹状形態に形成され凹状形態の左右端部面を各レール面５１として形成されているものとして以下説明する。
本実施の形態に係る移動体９７は、図３に示すように、例えばコロ体６３をもって構成したものである。
この移動体９７は、前記各架台に配置した各レール体５０の上下に対向する前記各レール面５１に上下から挟持され、地震等の振動発生の際、前記下部架台１０、中間部架台２０が夫々個別に直交する方向に自在に水平移動・平面移動可能な状態で、且つ、前記各架台に配置した各レール体５０の長さの範囲内においてレール面５１上を移動可能に構成したものであれば、本実施の形態以外の構成のものでも良い。
本実施の形態における前記移動体９７は、移動手段としての複数の一対の各コロ体６３からなり、この各コロ体６３は、上下に夫々対向配置した前記各凹状形態のレール体５０の左右の各レール面５１に当接しつつ当該レール面５１に上下から挟持され、且つ、芯軸６１の位置をもって対峙し一対となるような状態に夫々構成配置して構成したものである。
そして、図３に示すように、前記移動体９７は、間隔をもって立設した左右の各垂直片７６を有する例えば断面凹状のフレーム７７の当該各垂直片７６に、各コロ体６３、６３を回転可能に具備して構成したものである。
本実施の形態の移動体９７は、図１に示すように、この移動体９７の前記フレーム７７の両端部分に、前記対峙する一対の各コロ体６３を間隔をもって複数具備して構成している。レール面５１との関係におけるフレーム７７の両端部分に配置する各コロ体６３の間隔、距離幅は、狭ければ狭い程、各移動架台の夫々個別に直交する方向への水平移動・平面移動範囲を一層広くすることが可能である。
本発明においては、移動体９７に備えた各コロ体６３の前後位置の距離幅、或いはコロ体６３のサイズは、レール面５１の形状如何にかかわらず自在に決定できる。
この移動体９７は、図１、図３に示すように、前記上下対向する各レール面５１の間に夫々配置して免震装置１を構成する。
このような本実施の形態の移動体９７によれば、前記フレーム７７の両端部分に配置する各コロ体６３は、上下の各レール面５１に挟持されながら各レール面５１の可能な限り先端部分まで移動可能で、各移動架台の安定した水平移動・平面移動を確保できる。
次に、前記ストッパ体９０からなるストッパ機構部及び移動体９７が用いられる架台構成の一例を説明する。
すなわち、この免震装置１は、図１、図２に示すように、床面２上に配置する下部架台１０と、この下部架台１０の上に配置する中間部架台２０と、この中間部架台２０の上に配置する上部架台４０とを具備している。
図２中のＡは、美術品等々を収めている搭載又は展示ケースであり、この免震装置１は、例えば図２に示すような状態において使用される。
前記下部架台１０は、上面を開口１１とした四角形状の薄状箱型で、上方に向いて浅い溝部１２を設けて形成している。
前記中間部架台２０は、上・下面を夫々開口２１、２２とし、中心板２３の上下に夫々四角形状の薄状箱型を備えた形態で、この中心板２３の上方、下方に向いて夫々浅い溝部２４、２５を設け、上の溝部２４の部分を上方中間部架台２６、下の溝部２５の部分を下方中間部架台２７として形成している。
前記上部架台４０は、例えば図１に示すように、下面を開口４１とした四角形状の薄状箱型で、下方に向いた浅い溝部４２を設けて形成している。この上部架台４０の上に、コンピューター、精密機械等の機械器具等、又は美術品等が搭載又は展示される。
前記下部架台１０、中間部架台２０の上方中間部架台２６、下方中間部架台２７、上部架台４０は、図１、図２に示すように、各溝部が夫々相互に対向する各架台内に、夫々対向する各溝部内の左右位置に凹溝状、逆凹溝状の各レール体５０を配置している。
すなわち、前記下部架台１０の溝部１２の左右位置と、下方中間部架台２７の溝部２５の左右位置とには、相互に対向する溝部内の左右位置に凹溝状、逆凹溝状の各レール体５０を配置している。
また、前記上方中間部架台２６の溝部２４の左右位置と、上部架台４０の溝部４２の左右位置とには、図１、図２に示すように、前記下部架台１０の溝部１２と下方中間部架台２７の溝部２５とに配置した各レール体５０と直交し交叉する状態で、相互に対向する溝部内の左右位置に凹溝状、逆凹溝状の各レール体５０を配置している。
したがって、上方中間部架台２６の溝部２４と上部架台４０の溝部４２とに配置する各レール体５０と、前記下部架台１０の溝部１２と下方中間部架台２７の溝部２５とに配置する各レール体５０とは、直交させて交叉する状態で配置している。
前記下部架台１０の溝部１２と下方中間部架台２７の溝部２５とに配置する各レール体５０、５０の間と、前記上方中間部架台２６の溝部２４と上部架台４０の溝部４２とに配置する各レール体５０、５０の間には、下部架台１０の開口１１と下方中間部架台２７の開口２２との対向端面と、上方中間部架台２６の開口２１と上部架台４０の開口４１との対向端面とに、夫々隙間８１を設けながら、前記各架台に配置した各レール体５０の上下に対向する前記各レール面５１に上下から挟持され、地震等の振動発生の際、前記下部架台１０、中間部架台２０が夫々個別に直交する方向に自在に水平移動・平面移動可能な状態で、且つ、前記各架台に配置した各レール体５０の長さ内において前記レール面５１上を移動自在なように構成し前述したようなコロ体６３等を備えた移動体９７を具備している。
前記移動体９７の各コロ体６３は、前述したように、前記各架台に配置した各レール体５０の上下に対向する前記各レール面５１に上下から挟持されて、地震等の振動発生の際、前記下部架台１０、中間部架台２０が個別に直交する方向に自在に水平移動・平面移動可能な状態で、且つ、前記各架台に配置した各レール体５０の長さ内の一定範囲内において前記レール面５１上を移動自在な構成であれば良く、特にその構成を本実施の形態のものに限定するものではない。
したがって、前記下部架台１０、中間部架台２０の下方中間部架台２７、中間部架台２０の上方中間部架台２６、上部架台４０は、夫々の架台内に例えばコロ体６３等を備えた移動体９７を装着配置しているとともに、図１中の各矢印に示すように、地震等の振動発生の際には、下部架台１０、中間部架台２０とが夫々個別に直交する前後・左右の各方向に自在に振動を吸収しながら一層広い範囲の水平移動・平面移動が可能なように構成されて積層状態になっている。
故に、前記下部架台１０、中間部架台２０とが、夫々個別に直交する前後・左右の方向に自在に一層広い範囲で水平移動・平面移動することから、これにより、美術品等を搭載又は展示する上部架台４０を支持しているその下方部分があらゆる方向に動きながら振動を吸収して上部架台４０上の美術品等の倒壊等を防止することになる。
そして、このように構成した免震装置１には、図３等に示すように、前記下部架台１０と中間部架台２０の下方中間部架台２７との間、中間部架台２０の上方中間部架台２６と上部架台４０との間の左右位置に夫々配置した各レール体５０の間に、各架台間の各レール体５０に直交して配置され、水平移動・平面移動する各架台の脱落・外脱を可能に構成した前記ストッパ体９０からなるストッパ機構部を具備している。
本発明の実施の形態に係る免震装置１によれば、前記ストッパ体９０からなるストッパ機構部でもって水平移動・平面移動する各架台の脱落・外脱を常時防止しながら、下部架台１０、中間部架台２０が、夫々個別に直交する前後・左右の方向に一層広く自在に一層広い範囲で振動を吸収しつつ水平移動・平面移動可能な構成であることから、下部架台１０、中間部架台２０の各水平移動・平面移動が一層広い範囲でのオーバーハング状態でも安全に移動可能になるので、各架台のサイズを比較的小さくコンパクトに構成でき、本装置の設置場所も比較的狭いスペースで良く、例えば既存、既製の搭載又は展示ケースＡ等の内部に本装置をそのまま配置して適用することができる。
【発明の効果】
請求項１、２、３、４記載の各発明によれば、下部架台、中間部架台が、夫々個別に直交する前後・左右の方向に自在に一層広い範囲で振動を吸収しながら水平移動・平面移動可能な構成であることから、下部架台、中間部架台の各水平移動・平面移動が一層広い範囲でのオーバーハング状態でも安全に移動可能になるので、各架台のサイズを比較的小さくコンパクトに構成でき、本装置の設置場所も比較的狭いスペースで良く、例えば、既存、既製の搭載又は展示ケース等の内部に本装置をそのまま配置して適用可能で、しかも、各移動架台の脱落、外脱を円滑に防止できるとともに、各移動架台の安定した水平移動・平面移動を確保できる免震装置を提供できる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in each arrow of FIG. 1 and FIG. 2, the seismic isolation device 1 is configured to be able to absorb vibration while freely moving horizontally and in a plane in directions orthogonal to each other when a vibration such as an earthquake occurs. The lower frame 10 disposed on the floor 2, the intermediate frame 20 having the groove 25 disposed on the lower frame 10, and the groove 42 disposed on the intermediate frame 20. The apparatus includes an upper gantry 40 and is configured to protect an object to be mounted or an exhibit on the upper gantry 40 (for example, a mounting or an exhibition case A containing an artwork, etc.) from various vibrations such as an earthquake. .
A in FIG. 2 is a mounting case containing, for example, a work of art, and the seismic isolation device 1 is used in a state as shown in FIG. 2, for example.

Reference numeral 90 shown by a two-dot chain line in FIG. 1 is orthogonal to each rail body 50 arranged between the upper intermediate frame 26 and the upper frame 40 of the intermediate frame 20, and the upper intermediate frame. The stopper body which comprises the stopper mechanism part arrange | positioned between 26 and the upper mount frame 40 is shown as a conceptual diagram. The details of the stopper body 90 are as shown in FIG.
The stopper body 90 is also disposed between the lower frame 10 and the lower intermediate frame 27 of the intermediate frame 20 so as to be orthogonal to the rail bodies 50.
The stopper body 90 is for preventing the dropping and detachment of each pedestal that is horizontally moved and moved in a plane freely in directions orthogonal to each other when vibration such as an earthquake occurs. The interior of the gantry can be slid in a plane along the horizontal movement and the plane movement of each moving gantry, and can be returned to the initial position along the returning operation of each gantry to the initial position.
That is, as shown in FIG. 3, the stopper body 90 of the present embodiment is a rail fixed to each bottom surface of the lower frame 10 and the upper intermediate frame 26 so that the stopper body 90 can be slid in a plane within the frame. And a vertical shaft 74 which is fitted so that the bottom portion 73 does not come off the holding frame 72 and which stands up from the bottom portion 73 and is integrally formed with the bottom portion 73, and left and right sides of the vertical shaft 74.

According to the stopper body 90 and the stopper receiver 54 configured as described above, the lower surface of each roller 71 and the upper surface of the roller receiving surface 53 of the stopper receiver 54 are individually provided when vibration such as an earthquake occurs. When the pedestals that move horizontally or in a plane freely in the orthogonal direction reach the maximum possible movement, the rollers 71 are strongly joined to each other while rotating, and as a result, the movement of the moving pedestals stops. And prevent the base from falling off or coming off. Thereafter, the moving bases return to their initial positions while the lower surfaces of the rollers 71 and the upper surface of the roller receiving surface 53 of the stopper receiver 54 are gradually separated while the rollers 71 rotate.
Therefore, the stopper body 90 can be slid in a plane along the horizontal movement / planar movement of each moving base when moving each of the bases moving horizontally / planarly freely in directions orthogonal to each other individually. In addition, it is possible to return to the initial position along with the return operation of each moved platform to the initial position.
