本発明は、例えば美術品等を収めている搭載ケース等を、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用の免震装置に関し、詳しくは、水平可動可能として積層状態におかれる各架台の周囲側面部分に改良を施し、装置の免震機能に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物が装置内に侵入しないように装置の周囲側面に配置した側面カバー体が、如何なる場合にも装置内方に倒れ込むことのないような構造にした免震装置に関するものである。
【従来の技術】
この種の免震装置として、例えば、大小を問わず各種の地震等の振動発生の場合でも水平方向の振動を吸収することにより、床面に配置される台の上のコンピューター、精密機械等の機械器具、搭載台上の各種の搭載物、搭載ケース等に収納した各種搭載品等々が倒れてしまうような事態を防止できるとともに、地震等の発生振動が終わった後に、搭載台等を円滑に素早く元の位置へ復帰でき、しかも、設置場所も比較的狭いスペースで良く、既存、既製の搭載台、搭載ケース等にそのまま適用することができる装置としたものがある。
上記免震装置の要旨を説明すると次の通りである。
即ち、この免震装置は、床面等に配置する下部架台と、この下部架台の上方でコンピューター、精密機械等の機械器具等、又は美術品等を搭載する上部架台と、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、夫々個別に直交する方向に自在に水平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り、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、夫々上下に対向する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する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各レール面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、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内の一定範囲内においてレール面上を移動自在なように構成した移動体を具備し、前記下部架台の上面と中間部架台の下面のいずれかの一面、中間部架台の上面と上部架台の下面のいずれかの一面には、地震等の振動発生のとき、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する際における前記下部架台と中間部架台、及び中間部架台と上部架台の各水平移動に対して各架台の脱落・外脱を防止し、且つ、ストッパ受体と係止するように構成したストッパ体を具備してなることを要旨とするものである。
【発明が解決しようとする課題】
上述した免震装置は、例えば美術品等を収めている搭載ケース等を、地震をはじめとする各種振動から保護するための基本的構成の免震装置としては優れた作用、効果を発揮できるものである。

そして、架台の側面周囲の隙間から、架台の平面移動に阻害を与えるような物、例えば、埃、塵、虫等の異物が各架台内に侵入することを防止するための対策、手段が取られていないという事情、状況は、前記従来の免震装置ばかりでなく、地震等の振動発生の際平面移動するように構成した架台を具備し、この架台の平面移動により振動を吸収可能に構成し、架台上の被搭載物を地震等の各種振動から保護するようにした各種の免震装置の類についても同様である。
本発明は、上述した従来の免震装置をはじめとして、地震等の振動発生の際平面移動するように構成した架台を具備し、この架台の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の類に改良を施し、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、しかも、架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができるようにした装置の周囲側面に配置する側面カバー体を具備し、しかも、この側面カバー体が、如何なる場合にも装置内方に倒れ込むことのないような構造にした免震装置を提供することを目的とするものである。

請求項２記載の発明は、床面等に配置する下部架台と、この下部架台の上方で物品を搭載する上部架台と、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、夫々個別に直交する方向に自在に水平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、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、夫々上下に対向する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する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各レール面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、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内の一定範囲内においてレール面上を移動自在なように構成した移動体を具備し、前記中間部架台の下面で、各レール体の間を占める溝部内に配置した各レール体と同方向に中央部を底部とする傾斜面形状のストッパ受面を設けたストッパ受体と、前記下部架台の上面に高さ調整可能に配置した保持枠により支持されるとともに前記ストッパ受体のストッパ受面に対して接触するコロを備えるストッパ体と、前記上部架台の下面で、各レール体の間を占める溝部内に配置した各レール体と同方向に中央部を底部とする傾斜面形状のストッパ受面を設けたストッパ受体を配置し、前記中間部架台の上面に高さ調整可能に配置した保持枠により支持されるとともに前記ストッパ受体のストッパ受面に対して接触するコロを備えるストッパ体と、を具備し、
地震等の振動発生のとき、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する際における前記下部架台と中間部架台、及び中間部架台と上部架台の各水平移動に対して各架台の脱落・外脱を防止し、且つ、前記コロとストッパ受体との接触状態を調整することで下部架台、中間部架台の水平移動、及び、中間部架台、上部架台の水平移動の調整を可能に構成したことを特徴とする免震装置であり、この免震装置の周囲側面に免震装置の架台周囲側面を包覆するような状態で、且つ、その内側上端及び左右端にパイル状材、スポンジ状材、ゴム片材から選ばれる材料からなる介在具を有し、その内側下端に磁気板からなる磁気材を設けて構成され、その磁気力を予め設定した所定値以上の振動が発生して可動架台が水平移動した際には側面カバー体が床面方向に倒れるようになっているとともに、所定値未満の振動では架台の周囲側面を閉塞状態に包覆できるように構成した各側面カバー体を具備し、所定値以上の振動発生により可動架台が平面移動した状態で前記側面カバー体が装置の周囲側面から離反して床面方向へと倒れようとする際、前記各側面カバー体の左右両端が、これに対応する位置の各架台の各側面板の夫々の左右端部に衝突するようにした構成をもって、前記側面カバー体が決して装置の内方、即ち、架台の内方に倒れ込むようなことのないようにしたことを特徴とする免震装置における周囲側面部の改良構造である。
請求項１、２に記載の各発明によれば、各架台の側面周囲の各側面カバー体は、予め設定した所定値未満の架台の平面移動状態の下では架台の側面周囲から離反することなく安定状態を保持しながら密接状態で各架台の側面周囲を包覆しているので、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、しかも、各架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができる免震装置を実現できる。
そして、各側面カバー体は、各可動架台が静止状態で、予め設定した所定値未満の架台の平面移動状態の下では、装置の周囲側面から離反することなく安定状態を保持しながら各架台の側面周囲を包覆しているが、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態では、各側面カバー体は装置の周囲側面から離反して床面方向へと倒れることになり、このとき、本発明においては前記各架台の周囲の各側面板に前述のような改良を施しているので、各側面カバー体は、決して装置の内方、即ち、各架台の内方に倒れ込むようなことのない免震装置を実現できる。
更に、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オーバーハング状態で振動を吸収しながら水平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用の免震装置を実現できる。
この物品搭載用の免震装置は、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オーバーハング状態で振動を吸収しながら水平移動可能な構成であることから、上記各架台の水平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、ストッパ受体の動作と相まって、下部架台、中間部架台の各水平移動がかなり広い範囲まで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。
【発明の実施の形態】
次に、本発明の実施の形態を図面を参照して説明する。
本発明の物品搭載用免震装置における周囲側面部の改良構造が適用でき、この改良構造が施される対象である免震装置１は、例えば、図１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平面移動しながら振動を吸収可能に構成した積層状態に対向配置の各架台４０、２０、１０を具備し、且つ、例えば、図２、図４に示すように、装置の周囲側面に、装置の周囲側面を包覆するような状態で、内側上端及び左右端にパイル状材（毛状材）等からなる介在具１１０、内側下端に磁気板等の磁気材１１１を設けた各側面カバー体１１２を具備したものである。
前記側面カバー体１１２、即ち側面カバー体１１２に設けた磁気板等の磁気材１１１の磁気力は、要は、架台の静止状態で装置の周囲側面を閉塞状態に包覆でき、しかも、予め設定した所定値以上の振動が発生して可動架台が水平移動した際には、床面方向に倒れるようになっているとともに、所定値未満の振動では架台の静止状態と同様に装置の周囲側面を閉塞状態に包覆できるように構成したものであれば良い。
なお、前記側面カバー体１１２、介在具１１０、磁気板等の磁気材１１１の各構成は、図１、図４に示す構成のものに限定されるものではなく、上述したように、架台の静止状態で装置の周囲側面を閉塞状態に包覆でき、しかも、予め設定した所定値以上の振動が発生して可動架台が水平移動した際には、床面方向に倒れるようになっているとともに、所定値未満の振動では架台の静止状態と同様に装置の周囲側面を閉塞状態に包覆できるように構成したものであれば良い。
これにより、各側面カバー体１１２は、各可動架台が静止状態で、予め設定した所定値未満の架台の平面移動状態の下では、装置の周囲側面から離反することなく安定状態を保持しながら各架台の側面周囲を包覆している。また、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態では、各側面カバー体１１２は装置の周囲側面から離反して床面方向へと倒れることになる。そして、このとき、本発明においては後記各架台の周囲側面に改良を施しているので、各側面カバー体１１２は、決して装置の内方、即ち、架台の内方に倒れ込むようなことはない。
従って、架台が静止状態にあるとき、各架台周囲の側面は、各側面カバー体１１２により閉塞され包覆されている。
前記積層状態に対向配置した各架台の夫々の間には、前記下部架台１０、中間部架台２０を、各架台相互に対して、夫々個別に直交する方向に水平状態に自在に平面移動可能なように構成した例えば図１に示すような移動体９７を配置している。この移動体９７は、特に限定した構成を採用するものではなく、後記図２乃至図１２に示すようなコロ体６０をはじめ、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平面移動させることができる構成であれば、例えば、図１に示すような鋼材等からなる球体２０１を架台内から外脱しないような構成を施して配置する等々、如何なる構成のものでも良い。
上記本発明の物品搭載用免震装置における周囲側面部の改良構造が施される免震装置１の具体的な構造の一例ついては、後記図２乃至図１２を参照して説明する。
この他、本発明の物品搭載用免震装置における周囲側面部の改良構造は、水平可動可能として積層状態におかれる各架台を具備して、地震等の振動発生の場合、水平方向の振動を可動架台により吸収することにより、床面に配置される台の上のコンピューター、精密機械等の機械器具、搭載台上の各種の搭載物、搭載ケース等に収納した各種搭載品等々が倒れてしまうような事態を防止できるとともに、地震等の発生振動が終わった後に、搭載台等を円滑に素早く元の位置へ復帰できるようにした形態の各種の免震装置に適用できる。
本発明に係る物品搭載用免震装置における周囲側面部の改良構造は、図１乃至図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平面移動しながら振動を吸収可能に構成した対向配置の溝を有する四角形状の各架台、即ち上部架台４０、中間部架台２０、下部架台１０において、上部架台４０の下方に向いた溝部４２、下部架台１０の上方に向いた溝部１２、中間部架台２０の後記上下に向いたの各溝部２４、２５を形成している夫々の架台の周囲の各側面板２０２、２０３、２０４を改良したものである。
即ち、本実施の形態では、前記中間部架台２０の中心板２３の上下の各溝部２４、２５を形成している各側面板２０３の内、上方の溝部２４を形成している各側面板２０３のいずれか一方の対向面に各短い側面板２０３を形成し、この対向面と交叉する他の対向面の側面板を除去するとともに、下方の溝部２５を形成している各側面板２０３の上記上方の溝部２４の対向側面板２０３に上下方向で対向する各位置の側面板を除去し、上方の溝部２４の側面板を除去した対向面に上下方向で対向する各位置の対向面に各短い側面板２０３を形成している。
本実施の形態では、上方の各短い側面板２０３と、下方の各短い側面板２０３とを同じ高さに形成している。
そして、前記上部架台４０の溝部４２を形成している下方に向いた各側面板２０２の内、前記中間部架台２０の上方に向いて形成された各短い側面板２０３の上端と隙間を有しながら上下方向に対向する短い側面板２０２を、当該中間部架台２０の対向各側面板２０３と例えば同じ高さに形成するとともに、前記中間部架台２０の側面板を除去した各対向面の各位置と上下方向に対向し、且つ、中心板２３の上面と隙間を有するようにして設けた対向する各長い側面板２０２を、当該中間部架台２０の対向各側面板２０３の高さの例えば２倍の高さに形成している。
更に、前記下部架台１０の溝部１２を形成している上方に向いた各側面板２０４の内、前記中間部架台２０の下方に向いて形成された各側面板２０３の下端と隙間を有しながら上下方向に対向する短い側面板２０４を、当該中間部架台２０の対向各側面板２０３と例えば同じ高さに形成するとともに、前記中間部架台２０の側面板を除去した各対向面の各位置と上下方向に対向し、且つ、中心板２３の上面と隙間を有するようにして設けた対向する各長い側面板２０４を、当該中間部架台２０の対向各側面板２０３の高さの例えば２倍の高さに形成している。
前記各架台の各側面板２０２、２０３、２０４の高さは、要は、各架台の周囲側面の上下方向に対向する夫々の上下の面が適当な隙間を保持できる構成のものであるならば、本実施の形態例に限定されるものでないことは勿論である。
従って、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態で、各側面カバー体１１２は装置の周囲側面から離反して床面方向へと倒れることになるが、このとき、上部架台４０の各長い側面板２０２の夫々の左右端部と、この各部分に配置した各側面カバー体１１２の左右両端が相互に衝突するとともに、下部架台１０の各長い側面板２０４の夫々の左右端部と、この各部分に配置した各側面カバー体１１２の左右両端が相互に衝突するので、各側面カバー体１１２は、如何なる場合にも決して装置の内方、即ち、架台の内方に倒れ込むようなことはない。
図１中において、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。
このような周囲側面部に改良構造を施した免震装置１によれば、各架台の側面周囲の各側面カバー体１１２は、予め設定した所定値未満の架台の平面移動状態の下では架台の側面周囲から離反することなく安定状態を保持しながら密接状態で各架台の側面周囲を包覆しているので、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、しかも、各架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができる。
そして、前述した通り、これにより、各側面カバー体１１２は、各可動架台が静止状態で、予め設定した所定値未満の架台の平面移動状態の下では、装置の周囲側面から離反することなく安定状態を保持しながら各架台の側面周囲を包覆しているが、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態では、各側面カバー体１１２は装置の周囲側面から離反して床面方向へと倒れることになり、このとき、本発明においては前記各架台の周囲の各側面板２０２、２０３、２０４に前述のような改良を施しているので、各側面カバー体１１２は、決して装置の内方、即ち、各架台の内方に倒れ込むようなことはない。
以下、図２乃至図１２を参照して前述した周囲側面部の改良構造を施した免震装置１の架台構成の一例を説明する。
即ち、前述した周囲側面部の改良構造を施した免震装置１における架台構成の一例を説明すると、以下の通りである。
この免震装置１は、図２、図３等に示すように、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３中のＡは、前述したように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３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２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、搭載される。
そして、図２等に示すように、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平面移動しながら振動を吸収可能に構成した積層状態に対向配置の各架台４０、２０、１０を具備し、且つ、例えば、図２、図４に示すように、装置の周囲側面に、装置の周囲側面を包覆するような状態で、内側上端及び左右端にパイル状材（毛状材）等からなる介在具１１０、内側下端に磁気板等の磁気材１１１を設けた各側面カバー体１１２を具備して構成し、これらの各構成をもって免震装置における周囲側面部の改良構造としている。
前記側面カバー体１１２に設けた磁気板等の磁気材１１１の磁気力は、前述したように、要は、架台の静止状態で装置の周囲側面を閉塞状態に包覆でき、しかも、予め設定した所定値以上の振動が発生して可動架台が水平移動した際には床面方向に倒れるようになっているとともに、所定値未満の振動では架台の静止状態と同様に装置の周囲側面を閉塞状態に包覆できるように構成したものであれば良い。
また、前記側面カバー体１１２、介在具１１０、磁気板等の磁気材１１１の各構成は、前述したように、図１、中間部架台の図４に示す構成のものに限定されるものではなく、上述したように、架台の静止状態で装置の周囲側面を閉塞状態に包覆でき、しかも、予め設定した所定値以上の振動が発生して可動架台が水平移動した際には、床面方向に倒れるようになっているとともに、所定値未満の振動では架台の静止状態と同様に装置の周囲側面を閉塞状態に包覆できるように構成したものであれば良い。
従って、架台が静止状態にあるとき、架台周囲の側面は、各側面カバー体１１２により夫々各架台の周囲側面が閉塞されているとともに、各側面カバー体１１２の各磁気材１１１の磁気作用により一層安定状態を保持しながら各架台の側面周囲を包覆することになる。
このような免震装置１によれば、各架台の側面周囲の各側面カバー体１１２は、予め設定した所定値未満の架台の平面移動状態の下では各架台の側面周囲から離反することなく一層安定状態を保持しながら密接状態で各架台の側面周囲を包覆しているので、後記詳述する装置の内部構成をもって、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、しかも、各架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができる。
そして、本実施の形態では、前記中間部架台２０の中心板２３の上下の各溝部２４、２５を形成している各側面板２０３の内、上方の溝部２４を形成している各側面板２０３のいずれか一方の対向面に各短い側面板２０３を形成し、この対向面と交叉する他の対向面の側面板を除去するとともに、下方の溝部２５を形成している各側面板２０３の上記上方の溝部２４の対向側面板２０３に上下方向で対向する各位置の側面板を除去し、上方の溝部２４の側面板を除去した対向面に上下方向で対向する各位置の対向面に各短い側面板２０３を形成している。本実施の形態では、上方の各短い側面板２０３と、下方の各短い側面板２０３とを同じ高さに形成している。
そして、前記上部架台４０の溝部４２を形成している下方に向いた各側面板２０２の内、前記中間部架台２０の上方に向いて形成された各短い側面板２０３の上端と隙間を有しながら上下方向に対向する短い側面板２０２を、当該中間部架台２０の対向各側面板２０３と例えば同じ高さに形成するとともに、前記中間部架台２０の側面板を除去した各対向面の各位置と上下方向に対向し、且つ、中心板２３の上面と隙間を有するようにして設けた対向する各長い側面板２０２を、当該中間部架台２０の対向各側面板２０３の高さの例えば２倍の高さに形成している。
更に、前記下部架台１０の溝部１２を形成している上方に向いた各側面板２０４の内、前記中間部架台２０の下方に向いて形成された各側面板２０３の下端と隙間を有しながら上下方向に対向する短い側面板２０４を、当該中間部架台２０の対向各側面板２０３と例えば同じ高さに形成するとともに、前記中間部架台２０の側面板を除去した各対向面の各位置と上下方向に対向し、且つ、中心板２３の上面と隙間を有するようにして設けた対向する各長い側面板２０４を、当該中間部架台２０の対向各側面板２０３の高さの例えば２倍の高さに形成している。
前記各架台の各側面板２０２、２０３、２０４の高さは、要は、各架台の周囲側面の上下方向に対向する夫々の上下の面が適当な隙間を保持できる構成のものであるならば、本実施の形態例に限定されるものでないことは勿論である。
従って、前述した通り、各側面カバー体１１２は、各可動架台が静止状態で予め設定した所定値未満の架台の平面移動状態の下では、装置の周囲側面から離反することなく安定状態を保持しながら各架台の側面周囲を包覆しているが、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態では、側面カバー体１１２は装置の周囲側面から離反して床面方向へと倒れることになり、このとき、上部架台４０の各長い側面板２０２の夫々の左右端部と、この各部分に配置した各側面カバー体１１２の左右両端が相互に衝突するとともに、下部架台１０の各長い側面板２０４の夫々の左右端部と、この各部分に配置した各側面カバー体１１２の左右両端が相互に衝突するので、各側面カバー体１１２は、如何なる場合にも決して装置の内方、即ち、架台の内方に倒れ込むようなことはない。
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２、図４等に示すように、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。
即ち、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２、図５等に示すように、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。
従って、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、直交し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レール面５１上を移動自在なように構成した移動体９７、例えば、後記図１２に示すような各コロ６３等を備えたコロ体６０を具備している。
前記移動体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、特にその構成を限定するものではない。
例えば、図１２に示すような各コロ体６０をもって移動体９７を構成しても良い。
前記各レール体５０の長さ内の一定範囲内とは、各レール体５０の長さ内における一定の範囲という意味であり、後記するように、例えば、各レール体５０の長手方向の夫々の両端部に各垂直片５６を突設した場合には、前記移動体９７がこの各垂直片５６内におけるレール面５１上を移動自在となる。
従って、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、夫々の架台内に移動体９７、例えば各コロ体６０を装着配置しているとともに、図２中等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オーバーハング状態で振動を吸収しながら水平移動が可能なように構成されて積層状態になっている。
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オーバーハング状態で水平移動することから、これにより、美術品等を搭載する上部架台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。
なお、図２中の２点鎖線の引き出し線で示す符号７０又は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、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る後記ストッパ体９０又はストッパ体９０と異なる実施の形態のストッパ体７０である。
本発明の実施の形態においては、下部架台１０、中間部架台２０が、夫々個別に直交する前後・左右の方向に自在にオーバーハング状態で振動を吸収しながら水平移動可能な構成であることから、後記する上記各架台の水平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７０と相まって、下部架台１０、中間部架台２０の各水平移動がかなり広い範囲まで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。
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の各溝内に上下に配置する各レール体５０の上面のレール面５１は、夫々水平状態のレール面５１として実施しても良く、また、図５、図７等に示すように、各架台の下部の溝内に配置する各レール体５０のレール面５１を変形実施しても良い。
即ち、図５、図７等は、下部架台１０の溝部１２内のレール体５０のレール面５１と、上方中間部架台２６の溝部２４内のレール体５０のレール面５１とを、側面からみた場合、緩い傾斜の湾曲状部５２を形成して構成した状態を示すものである。
なお、中間部架台２０の下方中間部架台２７と上部架台４０との各溝内に配置する各レール体５０のレール面５１にも、前記下部架台１０の溝部１２内のレール体５０のレール面５１と上方中間部架台２６の溝部２４内のレール体５０のレール面５１とに構成したような側面からみた場合、緩い傾斜の湾曲状部５２を形成してこれを構成しても良い。
下部架台１０の溝部１２内のレール体５０のレール面５１と、上方中間部架台２６の溝部２４内のレール体５０のレール面５１とに、緩い湾曲状部５２を形成して構成した場合、下部架台１０、中間部架台２０と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の高効率な振動吸収を行うことができ、下部架台１０、中間部架台２０の各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である。
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の各溝内に上下に配置する各レール体５０の各端部には、図７等に示すように、前記下部架台１０、中間部架台２０の水平移動範囲の最大限（最大限のオーバーハング位置）を規制するための各垂直片５６を突設している。図８に示すように、移動する各架台がその移動の最大限の位置に達した時、移動体９７、例えば各コロ６３が各垂直片５６に当接し移動を停止する。
なお、上記垂直片５６は、これに代替して、各架台の内壁面をもって、当該垂直片５６と同じ作用を発揮するようにしても良い。
前記各レール体５０の長手方向の夫々の両端部に、各垂直片５６を突設した場合には、前述したように、前記移動体９７、例えばコロ６３がこの各垂直片５６内におけるレール面５１上を移動自在となる。
前記上部架台４０の溝部４２内の左右の各レール体５０と、前記中間部架台２０の下方中間部架台２７の溝部２５内の左右の各レール体５０とは、夫々内側方向に対向する各レール面５１の更に内側位置に、後記するストッパ体７０のコロ７１を搭載しこのコロ７１の受け体として、図４、図９に示すように、夫々適当幅を有する各ストッパ受面５３を設けたストッパ受体５４を形成している。
上記ストッパ受体５４の各ストッパ受面５３は、図９に示すように、水平に形成しても良く、また、図１０に示すように、側面からみた場合、底部５５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。
上記ストッパ受体５４の各ストッパ受面５３を、底部５５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。
なお、ストッパ受体５４の各ストッパ受面５３を、底部５５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、図１０に示すように下部架台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（図８の状態の時）、各コロ７１は当該ストッパ受面５３の傾斜面の最も高い部分に位置（図１０中の破線の部分）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。コロ７１が図１０の実線で示すように中央部分に位置するとき、下部架台１０、中間部架台２０は図７に示すような状態にある。
前記下部架台１０の溝部１２内と、前記中間部架台２０の上方中間部架台２６の溝部２４内とには、下部架台１０のレール体５０からの中間部架台２０の脱落・外脱を防止し、中間部架台２０のレール体５０からの上部架台４０の脱落・外脱を防止するため、下部架台１０の溝部１２内と中間部架台２０の上方中間部架台２６の溝部２４内の左右の各レール体５０の間に、これらの各レール体５０に直交する状態でストッパ体９０を具備している。
図５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との間に配置するストッパ体である。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との間に配置するストッパ体９０と同一構成で、下部架台１０と中間部架台２０の下方中間部架台２７との間に配置するストッパ体９０に直交して、中間部架台２０の上方中間部架台２６と上部架台４０との間に配置される。
本実施の形態の上記ストッパ体９０は、図５に示すように、左右両端に回転可能に設けた各コロ７１を有し、凹状の保持枠９３を支持する２つの各ナット９６を、下部架台１０の溝部１２内、中間部架台２０の上方中間部架台２６の溝部２４内に垂直に固設して構成している。
図５中の９１は、ナット９６に保持枠９３を支持しているナットである。
従って、この実施の形態においては、ナット９６への保持枠９３の高・低の支持位置をナット９１の締め付け状態により、自在に調整可能できるので、これにより、前記ストッパ受面５３へのコロ７１の接触状態を調整できることから、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の調整を自在にできる。
上記ストッパ体９０のコロ７１は、これ自体をコロの構成に限定するものではない。要は、ストッパ受面５３の接触状態を調整できるものであれば、単なる棒状としてこれを構成しても良い。この点、後述する変形する実施の形態におけるストッパ体７０のコロ７１も同様である。
なお、ストッパ受体５４の各ストッパ受面５３を、図９のように、水平に形成して構成した場合、図９に示すように、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（図８の状態の時）、各コロ７１は当該ストッパ受面５３の傾斜面の最も高い部分に位置（図９中の破線の部分）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。コロ７１が、図９の実線で示すように中央部分に浮上して位置するときは、下部架台１０、中間部架台２０は図７に示すような状態にある。
図６は、変更した実施の形態のストッパ体７０であり、凹状の保持枠７３の左右両端に回転可能に設けた各コロ７１を有し、この保持枠７３の中心位置に保持枠７３を、下部架台１０の溝部１２内、中間部架台２０の上方中間部架台２６の溝部２４内に垂直に固設するネジ芯棒９４と、これに装着するナット９２を具備している。上記変更した実施の形態のストッパ体７０の場合においても、前述したストッパ体９０の場合と同様に、ストッパ受体５４のストッパ受面５３は、図９、図１０に示すように、水平或いは底部５５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たものに適用できることは勿論である。
そして、前記保持枠７３の左右位置には、各ネジネジ芯棒７６の周囲に上下方向に付勢、弾性作用を発揮するバネ７７等の各弾性体７８を装着し、凹状の保持枠７３の底面にスペーサ７４を装着可能な隙間７５を有しつつ基板８０を、下部架台１０の溝部１２の底部、中間部架台２０の上方中間部架台２６の溝部２４の底部に固着している。
図６中の２点鎖線の引き出し線で示す符号７０は、中間部架台２０の上方中間部架台２６と上部架台４０との間に配置するストッパ体である。このストッパ体７０は、下部架台１０と中間部架台２０の下方中間部架台２７との間に配置するストッパ体７０と同一構成で、下部架台１０と中間部架台２０の下方中間部架台２７との間に配置するストッパ体７０に直交して、中間部架台２０の上方中間部架台２６と上部架台４０との間に配置される。
図６中、７９は各コロ７１のコロ軸、８２はバネ７７等の弾性体７８の上方に配置した押え板、８３はネジ芯棒７６を下部架台１０の溝部１２の底部、中間部架台２０の上方中間部架台２６の溝部２４の底部に固着するようにした場合のネジ頭である。
この場合、前記ストッパ体７０の左右の各コロ７１は、前記上部架台４０の溝部４２内と、中間部架台２０の下方中間部架台２７の溝部２５内との左右の各ストッパ受体５４のストッパ受面５３上に位置して、下部架台１０、中間部架台２０が夫々個別に直交する前後・左右の方向へ振動を吸収しながら自在な水平移動する際このストッパ受面５３上を回転するようになっている。
従って、この実施の形態においては、スペーサ７４を装着でき、弾性体７８の締め付け状態の強弱の調整ができ、これにより、前記ストッパ受面５３へのコロ７１の接触状態を調整できることから、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減衰の調整を自在にできる。
これにより、図９、図１０に示すような所に位置する場合のコロ７１を、自在に変更、調整（コロ７１の下面をストッパ受面５３に強弱を持たせながら当接させたり、浮上させたり）することにより、前記下部架台１０、中間部架台２０の各水平移動の減衰強弱を調整可能である。
なお、前記コロ体６０は、例えば図１２に示すように、左右の縦方向の上下端の部分に位置して各横軸材６１を固着した［］状に配置した各縦軸材６２と、各横軸材６１の左右端に垂直状に回転可能に具備した各コロ６３と、各コロ６３の内側に位置して［］状の各縦軸材６２の上下端に水平状に回転可能に具備した各コロ６４とを有している。
上記各横軸材６１の垂直状に回転可能な各コロ６３は、その上下端部が、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の各溝内に配置した各レール体５０の各レール面５１に上下方向から挟持されるように接触し、この状態で、前記下部架台１０、中間部架台２０が個別の水平方向に移動する際、各コロ６３は回転する。
各縦軸材６２の水平状に回転可能な各コロ６４は、水平状に対向する各コロ６４の各外側端部が、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の各溝内に配置した各レール体５０の各垂直内壁面５８に接触し、この状態で、前記中間部架台２０と上部架台４０との個別の水平方向に移動する際、各コロ６４は当該移動を案内する。
なお、コロ体６０は、図７、図８に示すように、前記下部架台１０、中間部架台２０が個別の水平方向の移動に沿って、それ自体が自在に移動する。
このように構成した本実施の形態に係る免震装置は、例えば、前記上部架台４０の上に、コンピューター、精密機械等の機械器具等、又は美術品等の搭載物を搭載して、これを使用状態においた場合、地震等各種の振動発生の際、下部架台１０、中間部架台２０が、夫々個別に直交する前後・左右の方向に自在にオーバーハング状態で振動を吸収しながら水平移動が可能なように構成されているので、上部架台４０上のコンピューター、精密機械等の機械器具、搭載物が倒壊してしまうような事態を防止できる。
そして、下部架台１０の溝部１２内のレール体５０のレール面５１と、上方中間部架台２６の溝部２４内のレール体５０のレール面５１とに、緩い湾曲状部５２を形成して構成した場合、前記下部架台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、地震等の発生振動が終わった後は、下部架台１０、中間部架台２０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。
また、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オーバーハング状態で水平移動することから、これにより、美術品等を搭載する上部架台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とともに、下部架台１０、中間部架台２０が、夫々個別に直交する前後・左右の方向に自在にオーバーハング状態で振動を吸収しながら水平移動可能な構成であることから、上記各架台の水平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７０と相まって、下部架台１０、中間部架台２０の各水平移動がかなり広い範囲まで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。
また、前記中間部架台２０の下方中間部架台２７、上部架台４０の各ストッパ受体５４の各ストッパ受面５３を、底部５５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、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。
また、前記ストッパ体９０のナット９６への保持枠９３の高・低の支持位置をナット９１の締め付け状態により、自在に簡易に調整可能できるので、これにより、前記ストッパ受面５３へのコロ７１の接触状態を調整できることから、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の調整を自在にできる。
更に、変更した実施の形態のストッパ体７０においては、スペーサ７４を装着でき、弾性体７８の締め付け状態の強弱の調整ができ、これにより、前記レール面５３へのコロ７１の接触状態を調整できることから、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減衰の調整を自在にできる。
このような架台構成の免震装置１に前記した側面カバー体１００を設けた装置によれば、前述した免震装置としての各作用、機能を発揮できる他、前記磁気板１０２と磁気板１０３とは、予め設定した所定値未満の架台の平面移動状態の下では離反することなく相互に磁着しているので、各架台の側面周囲を包覆するような状態で架台側面とカバー部１０１とが密接状態を保持できることから、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、しかも、各架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができる。
【発明の効果】
本発明の請求項１、２に記載の各発明によれば、各架台の側面周囲の各側面カバー体は、予め設定した所定値未満の架台の平面移動状態の下では架台の側面周囲から離反することなく安定状態を保持しながら密接状態で各架台の側面周囲を包覆しているので、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、しかも、各架台の側面周囲の隙間から、架台の平面移動に阻害、支障を与えるような物、例えば、埃、塵、虫等の異物の架台内への侵入を防止し、常時、平面可動する架台の円滑な平面移動を保持し、この種の装置の最良な作動状態を常時維持することができる免震装置を提供できる。
そして、各側面カバー体は、各可動架台が静止状態で、予め設定した所定値未満の架台の平面移動状態の下では、装置の周囲側面から離反することなく安定状態を保持しながら各架台の側面周囲を包覆しているが、予め設定した所定値以上の振動が発生して架台が平面移動状態した状態では、各側面カバー体は装置の周囲側面から離反して床面方向へと倒れることになり、このとき、本発明においては前記各架台の周囲の各側面板に前述のような改良を施しているので、各側面カバー体は、決して装置の内方、即ち、各架台の内方に倒れ込むようなことのない免震装置を提供できる。
更に、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オーバーハング状態で振動を吸収しながら水平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用の免震装置を提供できる。
この物品搭載用の免震装置は、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オーバーハング状態で振動を吸収しながら水平移動可能な構成であることから、上記各架台の水平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、ストッパ受体の動作と相まって、下部架台、中間部架台の各水平移動がかなり広い範囲まで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。

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
The improved structure of the peripheral side surface portion in the article-mounted seismic isolation device of the present invention can be applied, and the seismic isolation device 1 to which this improved structure is applied is, for example, as shown in FIG. In this case, each of the gantry 40, 20 and 10 is provided in a laminated state in which the vibrations can be absorbed while moving freely in a direction orthogonal to each other, and arranged opposite to each other. As shown in the figure, an intervening tool 110 made of a pile-like material (hair material) on the inner upper end and the left and right ends in a state of covering the peripheral side surface of the device, and a magnetic plate or the like on the inner lower end Each side cover body 112 provided with the magnetic material 111 is provided.
The magnetic force of the magnetic material 111 such as a magnetic plate provided on the side cover body 112, that is, the magnetic plate provided on the side cover body 112 is, in essence, the peripheral side surface of the apparatus can be covered in a closed state while the gantry is stationary, and is preset When the movable platform is horizontally moved due to the occurrence of vibration above the specified value, the floor is tilted in the direction of the floor. Any structure may be used as long as it can be covered in a closed state.
In addition, each structure of the magnetic material 111, such as the side surface cover body 112, the interposition tool 110, and the magnetic plate, is not limited to the structure shown in FIGS. 1 and 4, and as described above, the frame is stationary. In the state, the surrounding side surface of the device can be covered in a closed state, and when the movable cradle horizontally moves due to the occurrence of vibrations of a predetermined value or more that is set in advance, As long as the vibration is less than a predetermined value, any configuration may be used as long as the peripheral side surface of the apparatus can be covered in a closed state as in the stationary state of the mount.
As a result, each side cover body 112 is in a state where each movable gantry is in a stationary state and maintains a stable state without moving away from the peripheral side surface of the device under a plane movement state of the gantry below a predetermined value set in advance. It covers the side of the frame. Further, in a state where the vibration of a predetermined value or more set in advance is generated and the gantry is in a plane movement state, each side cover body 112 is separated from the peripheral side surface of the apparatus and falls in the floor surface direction. At this time, in the present invention, since the peripheral side surfaces of each pedestal are improved in the present invention, each side cover body 112 never falls into the inside of the apparatus, that is, the inside of the pedestal.
Accordingly, when the gantry is in a stationary state, the side surfaces around the gantry are closed and covered by the side surface cover bodies 112.
Between each of the platforms opposed to each other in the stacked state, the lower frame 10 and the intermediate frame 20 can be freely moved in a horizontal state in a direction perpendicular to each frame individually. For example, a moving body 97 as shown in FIG. 1 is arranged. This moving body 97 does not adopt a particularly limited configuration, and includes a roller body 60 as shown in FIGS. 2 to 12 to be described later, and directions in which each gantry is orthogonal to each other when vibration such as an earthquake occurs. Any configuration can be used as long as it can be freely moved in a plane, for example, a sphere 201 made of steel or the like as shown in FIG. good.
An example of a specific structure of the seismic isolation device 1 provided with the improved structure of the peripheral side surface portion in the article mounting seismic isolation device of the present invention will be described with reference to FIGS.
In addition, the improved structure of the peripheral side surface in the article-mounting seismic isolation device according to the present invention includes each frame placed in a stacked state so as to be horizontally movable. Absorption by the movable base will cause the computer on the base placed on the floor, machinery such as precision machinery, various types of mounted items on the mounting base, various mounted items stored in the mounting case, etc. to fall down. Such a situation can be prevented, and it can be applied to various types of seismic isolation devices in which the mounting base can be smoothly and quickly returned to the original position after the occurrence of vibration such as an earthquake.
As shown in FIGS. 1 and 2, the improved structure of the peripheral side surface portion in the article-mounting seismic isolation device according to the present invention moves freely in the direction orthogonal to each other when vibrations such as earthquakes occur. In each quadrangular frame having opposed grooves configured to absorb vibration, that is, the upper frame 40, the intermediate frame 20, and the lower frame 10, the groove 42 facing downward of the upper frame 40, and the upper frame 10 The side plates 202, 203, 204 around the respective frames forming the groove portions 24, 25 facing the upper and lower sides of the groove portion 12 and the intermediate portion frame 20 are improved.
That is, in the present embodiment, among the side plates 203 that form the upper and lower grooves 24 and 25 of the center plate 23 of the intermediate frame 20, the side plates 203 that form the upper groove 24. The short side plates 203 are formed on any one of the opposing surfaces, the side plates on the other opposing surfaces that intersect the opposing surfaces are removed, and the side plates 203 that form the lower grooves 25 are described above. The side plate at each position facing the opposing side plate 203 of the upper groove portion 24 in the vertical direction is removed, and each of the opposing surfaces at each position facing the vertical surface from which the side plate of the upper groove portion 24 is removed is short. A side plate 203 is formed.
In the present embodiment, the upper short side plates 203 and the lower short side plates 203 are formed at the same height.
Of the side plates 202 facing downward that form the grooves 42 of the upper frame 40, there are gaps between the upper ends of the short side plates 203 formed facing upward of the intermediate frame 20. However, the short side plates 202 that face each other in the vertical direction are formed at, for example, the same height as the opposing side plates 203 of the intermediate frame 20, and the positions of the opposing surfaces from which the side plates of the intermediate frame 20 are removed. Each of the opposing long side plates 202 that are provided so as to be opposed to each other in the vertical direction and have a gap with the upper surface of the center plate 23 is, for example, twice the height of the opposing side plates 203 of the intermediate frame 20. It is formed at a height of
Further, among the side plates 204 facing upward that form the grooves 12 of the lower pedestal 10, there is a gap with the lower end of each side plate 203 formed facing the lower side of the intermediate pedestal 20. The short side plates 204 opposed in the vertical direction are formed at the same height as the opposed side plates 203 of the intermediate frame 20, for example, and the positions of the opposing surfaces from which the side plates of the intermediate frame 20 are removed are as follows. Each of the opposing long side plates 204 that are vertically opposed and provided so as to have a gap with the upper surface of the center plate 23 is, for example, twice the height of each of the opposing side plates 203 of the intermediate frame 20. It is formed to the height.
The height of each side plate 202, 203, 204 of each gantry is basically configured so that the upper and lower surfaces facing each other in the vertical direction of the peripheral side surface of each gantry can hold an appropriate gap. Of course, the present invention is not limited to this embodiment.
Therefore, each side cover body 112 falls away from the peripheral side surface of the apparatus and falls in the floor direction in a state where the vibration exceeding the predetermined value set in advance is generated and the gantry is in a plane movement state. The left and right end portions of each long side plate 202 of the upper gantry 40 and the left and right ends of each side cover body 112 disposed in each portion collide with each other, and each of the long side plates 204 of the lower gantry 10 respectively. Since the left and right end portions of the side cover and the left and right ends of the side cover bodies 112 disposed in the respective portions collide with each other, the side cover bodies 112 are never inward of the apparatus, that is, inward of the gantry. There is no such thing as falling down.
In FIG. 1, the intermediate frame 20 has openings 21 and 22 on the upper and lower surfaces, respectively, and is provided with a rectangular thin box shape above and below the center plate 23, above the center plate 23, The shallow groove portions 24 and 25 are provided facing downward, and the upper groove portion 24 is formed as the upper intermediate frame 26 and the lower groove portion 25 is formed as the lower intermediate frame 27.
According to the seismic isolation device 1 having an improved structure on the peripheral side surface, each side cover body 112 around the side surface of each pedestal is placed under the pedestal plane movement state less than a predetermined value set in advance. Since the surroundings of the sides of each pedestal are covered in close contact with each other while maintaining a stable state without separating from the surroundings of the sides, vibrations such as earthquakes can be absorbed by the plane movement of the gantry, and when vibrations such as earthquakes occur While it has a function to absorb vibrations by moving the platform and protect the load on the platform from various vibrations such as earthquakes, it also obstructs and hinders the movement of the platform from the gap around the side of each frame. To prevent the entry of foreign objects such as dust, dust, and insects into the gantry, and to maintain the smooth plane movement of the gantry that is movable at all times. It can be maintained at all times.
As described above, this makes it possible for each side cover body 112 to be stable without being separated from the peripheral side surface of the apparatus under the state in which each movable platform is stationary and the platform is moved in a plane less than a predetermined value. While the state is maintained, the periphery of the side surface of each gantry is covered. However, in the state where the gantry is in a plane movement state due to the occurrence of vibration of a predetermined value or more, each side cover body 112 is moved from the peripheral side surface of the device In this case, in the present invention, the side plates 202, 203, and 204 around the mounts are improved as described above. 112 never falls into the inside of the device, i.e. inside each pedestal.

The shallow groove portions 24 and 25 are provided, and the upper groove portion 24 is formed as the upper intermediate frame 26 and the lower groove portion 25 is formed as the lower intermediate frame 27.
For example, as shown in FIG. 2, the upper frame 40 is a rectangular thin box shape having an opening 41 on the lower surface, and is formed with a shallow groove portion 42 facing downward. On this upper mount 40, a machine, such as a computer or a precision machine, or a work of art is mounted.
Then, as shown in FIG. 2 and the like, when a vibration such as an earthquake occurs, each of the gantry 40, 20 facing each other in a stacked state configured to be able to absorb vibration while freely moving in a plane in directions orthogonal to each other, 10 and, for example, as shown in FIG. 2 and FIG. 4, pile-like materials (hair-like) are formed on the inner upper end and the left and right ends in a state of covering the peripheral side surface of the device.

As described above, the magnetic force of the magnetic material 111 such as a magnetic plate provided on the side cover body 112 can, as a matter of course, cover the peripheral side surface of the apparatus in a closed state while the gantry is stationary, and is set in advance. When the movable platform moves horizontally due to the occurrence of vibration above the specified value, it will fall down to the floor surface, and if the vibration is less than the specified value, the peripheral side of the device will be closed like the stand still Any structure can be used as long as it can be covered.
Moreover, each structure of the magnetic material 111 such as the side cover body 112, the interposition tool 110, and the magnetic plate is not limited to the structure shown in FIG. 1 and FIG. 4 of the intermediate frame as described above. As described above, when the gantry is stationary, the peripheral side surface of the device can be covered with a closed state, and when the movable gantry moves horizontally due to the occurrence of vibration exceeding a predetermined value, the floor surface direction As long as the vibration is less than a predetermined value, the peripheral side surface of the apparatus can be covered in a closed state as in the stationary state of the gantry.
Therefore, when the gantry is in a stationary state, the side surfaces around the gantry are closed by the side cover bodies 112 and the side surfaces around the gantry are closed, and the magnetic action of each magnetic material 111 of each side cover body 112 further increases. The surroundings of the side surfaces of each gantry are covered while maintaining a stable state.
According to such a seismic isolation device 1, each side cover body 112 around the side surface of each gantry is further separated from the periphery of the side surface of each gantry under a plane movement state of the gantry below a predetermined value set in advance. Since the sides of each frame are covered in close contact with each other while maintaining a stable state, the internal structure of the device described in detail later can absorb vibrations such as earthquakes by moving the frame in a plane, and vibrations such as earthquakes. In the event of occurrence, it has the function of absorbing vibrations by moving the platform and protecting the load on the platform from various types of vibration such as earthquakes. It prevents the entry of foreign objects such as dust, dust, insects, etc., into the gantry, and keeps the pallet moving smoothly on the plane. The operating state can be maintained at all times.
In this embodiment, among the side plates 203 that form the upper and lower grooves 24 and 25 of the center plate 23 of the intermediate frame 20, the side plates 203 that form the upper grooves 24. The short side plates 203 are formed on any one of the opposing surfaces, the side plates on the other opposing surfaces that intersect the opposing surfaces are removed, and the side plates 203 that form the lower grooves 25 are described above. The side plate at each position facing the opposing side plate 203 of the upper groove portion 24 in the vertical direction is removed, and each of the opposing surfaces at each position facing the vertical surface from which the side plate of the upper groove portion 24 is removed is short. A side plate 203 is formed. In the present embodiment, the upper short side plates 203 and the lower short side plates 203 are formed at the same height.
Of the side plates 202 facing downward that form the grooves 42 of the upper frame 40, there are gaps between the upper ends of the short side plates 203 formed facing upward of the intermediate frame 20. However, the short side plates 202 that face each other in the vertical direction are formed at, for example, the same height as the opposing side plates 203 of the intermediate frame 20, and the positions of the opposing surfaces from which the side plates of the intermediate frame 20 are removed. Each of the opposing long side plates 202 that are provided so as to be opposed to each other in the vertical direction and have a gap with the upper surface of the center plate 23 is, for example, twice the height of the opposing side plates 203 of the intermediate frame 20. It is formed at a height of
Further, among the side plates 204 facing upward that form the grooves 12 of the lower pedestal 10, there is a gap with the lower end of each side plate 203 formed facing the lower side of the intermediate pedestal 20. The short side plates 204 opposed in the vertical direction are formed at the same height as the opposed side plates 203 of the intermediate frame 20, for example, and the positions of the opposing surfaces from which the side plates of the intermediate frame 20 are removed are as follows. Each of the opposing long side plates 204 that are vertically opposed and provided so as to have a gap with the upper surface of the center plate 23 is, for example, twice the height of each of the opposing side plates 203 of the intermediate frame 20. It is formed to the height.
The height of each side plate 202, 203, 204 of each gantry is basically configured so that the upper and lower surfaces facing each other in the vertical direction of the peripheral side surface of each gantry can hold an appropriate gap. Of course, the present invention is not limited to this embodiment.
Therefore, as described above, each side cover body 112 maintains a stable state without moving away from the peripheral side surface of the apparatus when the movable platform is stationary and the platform is in a plane movement state less than a predetermined value set in advance. However, the side cover body 112 is separated from the peripheral side surface of the apparatus in the state where the periphery of the side surface of each base is covered, but the vibration of the predetermined value or more that is set in advance is generated and the base is in a plane movement state. At this time, the left and right ends of each long side plate 202 of the upper frame 40 and the left and right ends of each side cover body 112 disposed in each portion collide with each other, and the lower Since the left and right ends of each long side plate 204 of the gantry 10 and the left and right ends of each side cover body 112 arranged in each portion collide with each other, each side cover body 112 is never mounted in any case. Of the inner, that is, is not it, such as falling down the inside of the frame.

The body 50 is arranged.
Further, the left and right positions of the groove portion 24 of the upper intermediate frame 26 and the left and right positions of the groove portion 42 of the upper frame 40 are, as shown in FIGS. The rail bodies 50 having a concave groove shape and a reverse concave groove shape are arranged at left and right positions in the mutually facing groove portions in a state of being orthogonal to and intersecting with the rail bodies 50 arranged in the groove portion 25 of the mounting base 27. .
Accordingly, each rail body 50 disposed in the groove portion 24 of the upper intermediate frame 26 and the groove portion 42 of the upper frame 40, and each rail body disposed in the groove portion 12 of the lower frame 10 and the groove portion 25 of the lower intermediate frame 27. 50 is arranged in a state of crossing at right angles.

Between each rail body 50, 50, the opposed end surface of the opening 11 of the lower frame 10 and the opening 22 of the lower intermediate frame 27, and the facing of the opening 21 of the upper intermediate frame 26 and the opening 41 of the upper frame 40 are provided. While being provided with a gap 81 on each end surface, the rail body 50 is vertically held between the rail bodies 51 opposed to the top and bottom of the rail bodies 50. When the vibration such as an earthquake occurs, It is possible to move on the rail surface 51 within a certain range within the length of each rail body 50 arranged on the respective bases in a state in which the base bases 20 can be horizontally moved freely in directions orthogonal to each other. Mobile body 9 configured in , For example, comprises a roller body 60 having a respective roller 63 or the like as shown in the following Figure 12.
The movable body 97 is sandwiched from above and below by rail surfaces 51 facing the top and bottom of the rail bodies 50 arranged on the respective bases, and when the vibration such as an earthquake occurs, the lower base 10 and the intermediate part base 20 are As long as it is configured to be movable on the rail surface 51 within a certain range within the length of each rail body 50 arranged on each gantry in a state where it can be moved horizontally in a direction orthogonal to each other individually, The configuration is not particularly limited.
For example, you may comprise the moving body 97 with each roller body 60 as shown in FIG.
The term “within a certain range within the length of each rail body 50” means a certain range within the length of each rail body 50, and, as will be described later, for example, each of the rail bodies 50 in the longitudinal direction. When each vertical piece 56 protrudes from both ends, the movable body 97 can move on the rail surface 51 in each vertical piece 56.
