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、この種の免震装置の水平に積層配置される各架台間に上下に対向設置する各レール体の間に配置されて各架台の水平移動・平面移動を確保するための移動体（コロ体）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）における水平に積層配置される各架台間に、上下に対向設置する各レール体の間に配置されて各架台の水平移動・平面移動を確保するための移動体（コロ体）に改良を施し、前記移動する各架台の脱落、外脱を円滑に防止できるとともに、前記移動体を、常時、上下の対向レール面に馴染むような状態で各架台の安定した水平移動・平面移動を確保できるように構成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、床面等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、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されるとともに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とした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、夫々上下に対向配置されるとともに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とし、且つ、各レール面を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体を具備し、前記各レール面を、中央が低く両端が高い傾斜面に形成し、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る状態で水平配置される移動体であって、間隔をもって立設した左右の垂直片を有するフレームと、前記フレームの左右の垂直片に、異なる芯軸位置をもって対峙し一対となるような状態に夫々配置し、かつ、間隔をもって複数配置した各コロ体を具備する移動体を具備し、前記対峙する一対のコロ体の内のいずれか一方のコロ体は、その本体の両端に、前記レール面の左右端部を包覆可能で、径がフレーム側が小さく外側が大きい各突出盤又はフランジを具備して、突出盤又はフランジ付きの複数のコロ体の前記フレームへの片側配置形態とし、前記突出盤又はフランジを具備しないコロ体を、前記フレームの長さ方向に関して突出盤又はフランジを具備するコロ体よりも端部側に配置し、前記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・平面移動及び移動した各架台の初期位置への復帰を円滑に行うように構成し、且つ、前記移動する各架台の脱落、外脱を円滑に防止するとともに、前記移動体を、常時、上下の対向レール面に馴染むような状態で各架台の安定した水平移動・平面移動を確保できるように構成した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、前記フレームの端面に、緩衝作用を有する弾性材を具備することを特徴とするものである。
請求項１、２記載の各免震装置によれば、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、移動体自体を、常時、上下の対向レール面に馴染むような状態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。
本発明に係る実施の形態の改良した例えばコロ体等からなる移動体９７の構成は以下の通りである。
本実施の形態の改良した移動体９７は、例えば図１、図２に示すような免震装置１、すなわち、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されて、床面２上に配置する下部架台１０と、この下部架台１０の上に溝部８１を介して配置する中間部架台２０と、この中間部架台２０の上に溝部８１を介して配置する上部架台４０とを具備し、上部架台４０上の被搭載又は展示物（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免震装置１に用いるものである。
そして、本実施の形態の改良した移動体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、例えば後述する図１に示すように、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改良した移動体９７は、図３乃至図５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。
本発明の移動体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、異なる芯軸７１、７２（図３参照）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たとともに、前記対峙する一対の各コロ体６３の内のいずれか一方のコロ体は、その本体７３の両端に、前記レール面５１の左右端部を包覆可能な各突出盤又はフランジ７４、７５を具備して構成したものである。
そして、図３乃至図５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と、前記フレーム７７の左右の垂直片７６に、異なる芯軸７１、７２の位置をもって対峙し一対となるような状態に夫々配置した各コロ体６３、６３とを具備して構成したものである。
なお、本実施の形態においては、前記対峙する一対の各コロ体６３の内のいずれか一方のコロ体の両端に設けた各突出盤又はフランジ７４、７５の径を異にして形成しているが、当該各突出盤又はフランジ７４、７５の径の異同を限定するものではない。
前記芯軸７１、７２は、これ自体が、各コロ体６３を前記フレーム７７の左右の垂直片７６に装着するための頭部７８、ねじ部７９を具備していて、当該芯軸７１、７２は各コロ体６３の中心孔８０に挿通され、各コロ体６３が回転自在となるように構成されている。
本実施の形態の移動体９７は、図３、図４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。
なお、図３、図４中の符号９０は、フレーム７７の左右端面に貼着、装着したゴム材、スポンジ材等の弾性材を示すものである。移動体９７、すなわち、各コロ体６３が各レール体５０の両端部の極限位置で自ら自動停止する状態になったとき、各架台の側面内壁に当該弾性材９０が当たることになるので、その際の緩衝作用を発揮するものである。
このようにして構成した移動体９７は、図１、図２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改良した移動体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あることは勿論、異なる芯軸７１、７２をもって一対とする各コロ体６３からなるこの移動体９７は、この移動体９７を用いる前記レール体５０の適当な傾斜配置（例えば左右いずれかのレール体のレール面を図１に示すように中央が低く両端が高い傾斜面にする）と相まって、当該各コロ体６３が各レール体５０の両端部の極限位置で自ら自動停止する状態になることから、前記移動する各移動架台の脱落、外脱を円滑に防止できるとともに、移動体９７自体を、常時、上下の対向レール面５１に馴染むような状態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、前記図３乃至図５に示す本実施の形態に係る移動体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。
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。
従って、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。
なお、このように構成した免震装置１には、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ストッパ体（図示せず）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、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。
本発明の実施の形態の免震装置１によれば、移動体９７の構成を前記のように構成したので、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あることは勿論、異なる芯軸７１、７２をもって一対とする各コロ体６３からなるこの移動体９７は、この移動体９７を用いる前記レール体５０の適当な傾斜配置（例えば左右いずれかのレール体を内方に傾斜させて配置）と相まって、当該各コロ体６３が各レール体５０の両端部の極限位置で自ら自動停止する状態になることから、前記移動する各移動架台の脱落、外脱を円滑に防止できるとともに、移動体９７自体を、常時、上下の対向レール面５１に馴染むような状態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。
【発明の効果】
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、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、移動体自体を、常時、上下の対向レール面に馴染むような状態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免震装置を提供できる。
