Description

【0001】
【発明の属する技術分野】
本発明は、実験台に関し、特に棚部材上に載置された実験用機器類から液体が漏出した場合に対処できるようにするとともに、高速クロマトグラフ分析装置などの使用時の利便性も図れるようにした実験に関する。
【0002】
【従来の技術】
一般に実験台では、同実験台上の棚部材に載置された実験用機器類が地震などの際に倒れないように、同棚部材に先端部を取り付けられるベルトで、上記実験用機器類を拘束することが提案されている。
【0003】
【発明が解決しようとする課題】
ところで、前述のように実験台上の棚部材に載置された実験用機器類がベルトで拘束されると、その転倒は防止されるが、激しく揺れると同機器類に含まれた液体が漏出する恐れがあり、このようにして棚部材の下方へ液体が垂れ落ちると、同棚部材の直下に設けられた他の実験用機器類に上記液体が降りかかって、同機器類の損傷を招く恐れがある。
【0004】
そこで本発明は、棚部材上に載置された実験用機器類から液体が漏出した場合でも、その漏洩液体を適切に受け止められるようにして、同棚部材の直下の他の実験用機器類を防護できるようにし、また液体クロマトグラフ分析装置などから流出する液体の処理も能率よく行えるようにした実験を提供することを課題とする。
【0005】
【課題を解決するための手段】
前述の課題を解決するため、本発明の実験は、液体を含んだ実験用機器類を載置し、同実験用機器類から漏出した液体を導入する通孔が上面に形成された棚部材と、同棚部材の下側に設けられ上記通孔に流入し落下する液体を受け入れるための容器とを有する実験用機器類載置棚装置が、天板の上面に立設固定されていることを特徴としている。
【0006】
また、本発明の実験は、上記通孔に、上記実験用機器類を拘束するベルトの先端止具が係止されることを特徴としている。
【0007】
さらに、本発明の実験は、上記棚部材の周縁に沿い、同棚部材上に流出した液体を堰止める液密のフェンスが立設されたことを特徴としている。
【0008】
また、本発明の実験は、上記実験用機器類に接続された電源ケーブルや信号ケーブル類の余長中間条体部を収容しうるダクト部材が、水平状態で上記フェンスに引掛けられるフック部をそなえて装着されたことを特徴としている。
【0009】
さらに、本発明の実験は、上記ダクト部材の壁部に、上記余長中間条体部の出入を許容する複数の窓穴が形成されていることを特徴としている。
【0010】
また、本発明の実験は、上記容器の底部に排液口が形成され、同排液口に接続された排液管と、同排液管を通じ排液を受ける下部容器とが設けられたことを特徴としている。
【0011】
さらに、本発明の実験は、上記フェンスが、上記棚部材の上面を形成する板材の曲げ加工により同棚部材の上面と一体に構成され、同フェンスの内側面が上記棚部材の上面に対し鈍角をなすように傾斜するとともに、同フェンスの外側面がほぼ鉛直面をなすように形成されていることを特徴としている
【0012】
また、本発明の実験は、上記棚部材の上面に、同棚部材上の実験用機器類に接続された液体流通用チューブを通して下方へ延在させるための小孔が形成され、同小孔の内周縁と上記チューブの外周面との間を液密に塞ぐリング状パッキンが設けられていることを特徴としている。
【0013】
上述の本発明の実験では、地震などに際して、実験用機器類を載置する棚部材の上面に、同棚部材上の実験用機器類から薬液などの液体が漏出した場合に、同棚部材の上面に形成された通孔を通じて上記の漏出した液体が流下し、同棚部材の下側に装着された容器で受止められるので、同液体が上記棚部材の下方に設置された他の実験用機器類を損傷させるのを十分に防止することができる。
【0014】
また、上記通孔に上記実験用機器類を拘束するベルトの先端止具が係止されるようになっていると、上記通孔が漏洩液体の集液孔とベルト先端止具の係止孔とを兼ねることになり、構造の簡素化がもたらされるようになる。
【0015】
さらに、上記棚部材の周縁に沿い、同棚部材上に流出した漏洩液体を堰止める液密のフェンスが立設されていると、上記漏洩液体が前記の通孔に入りきれずに上記棚部材上面に沿い流出して下方へ垂れ落ちるのを十分に防止することができる。
【0016】
また、上記実験用機器類に接続された電源ケーブルや信号ケーブル類の余長中間条体部を収容しうるダクト部材が、フック部を介し水平状態で上記フェンスに引掛けられるようになっていると、従来、実験台の裏側などにもつれ込んでいた電源ケーブルなどの余長中間条体部が整理されるようになって、実験用機器類の入換え作業などが大幅に簡便化されるようになる。
【0017】
さらに、上記ダクト部材の壁部に、上記余長中間条体部の出入を許容する複数の窓穴が形成されていると、実験用機器類に接続された前記の電源ケーブルや可撓チューブ類の配置および処理操作が、無駄なく適切に行なわれるようになる。
【0018】
また、棚部材下側の容器の底部に排液口を形成して、同排液口に接続された排液チューブを介し下部容器に排液を受ける構成になっていると、上記下部容器の交換だけで排液の処理が著しく容易に行われるようになり、棚部材下側の容器をいちいち取外さなくてすむ利点が得られる。
【0019】
さらに、上記棚部材の周縁に設けられるフェンスが、上記棚部材の上面を形成する板材の曲げ加工により同棚部材の上面と一体に構成されて、同フェンスの内側面が上記棚部材の上面に対し鈍角をなす傾斜面として形成され、同フェンスの外側面がほぼ鉛直面をなすように形成されていると、上記フェンスの剛性が増して強度上有利になるとともに、液漏れを起こすことが無く、製作時の工程が絞り加工などにより簡易化されるようになり、また上記フェンスに膨らみをもたせることができるので、見栄えも向上する。
【0020】
また、上記棚部材の上面に、同棚部材上の液体クロマトグラフィーによる分析などのための実験用機器類から下方へ延在する液体流通用チューブを通過させるようにした小孔が形成されて、同小孔の内周縁と上記チューブの外周面との間を密封するリング状パッキンが設けられると、液体処理を伴う実験用機器類の上記棚部材上への搭載が支障なく行われ、しかも棚部材上面への液体漏洩事故が生じても上記パッキンにより棚部材から下方への液体漏洩は防止され、漏洩液は棚部材に形成された前述の液体導入用通孔を介し同通孔の下方の容器に安全に受け入れられるようになる。
【0021】
【発明の実施の形態】
以下、図面により本発明の実施形態について説明すると、図1は液体クロマトグラフィーによる分析などに用いられる本発明の一実施形態としての実験の正面図、図2は図1のA矢視側面図、図3は図1のB矢視平面図、図4は図1のC−C断面拡大図、図5は図1の実験の一部の使用状態を示す斜視図、図6は図1の実験の変形例における一部の使用状態を示す斜視図、図7は図6の棚部材のフェンスに引掛けられて使用される小物入れを示す斜視図であり、図8は図5におけるダクト部材の端面図である。また、図9は図4の要部の変形例を示す断面図、図10は図9のD矢視図、図11は図9の棚部材の一部を示す断面図、図12は図11に示すパッキンの付近の拡大図、図13は図11に示す棚部材をそなえた実験台の要部斜視図、図14は図13に示す実験台の天板の一部を示す斜視図、図15は図14の天板に用いられているリング部材およびスペーサの分解図、図16は図4の装置の他の変形例を示す断面図である。
【0022】
図1〜3に示すように、天板1aを支持脚1bで支えるようにした実験台1において、天板1aの上面に、電源ケーブル等の通過配設を許容しうる複数の中空の柱体ユニット2が立設固定されており、両側部の柱体ユニット2,2の中間部を相互に強固に連結する中空のビームユニット3が水平に架設されている。そして両側部の柱体ユニット2,2の相互間には棚部材4が着脱可能に架設されていて、同棚部材4上には図5,6に示すように実験用機器類5が搭載され、同機器類5には電源ケーブルや信号ケーブル類14が接続されるほか、流体を通す可撓チューブ類14pが接続されている。
【0023】
また、棚部材4の上面には、図3および図4に示すように棚部材4上に載置された実験用機器類5(図6参照)から地震などの際に同棚部材4上に漏出した液体を能率よく導入する2条の互いに平行な通孔6が形成されており、同通孔6に流入し落下する液体を受け入れるための容器7が、棚部材4の下側に着脱可能に設けられている。
【0024】
すなわち、棚部材4の下面に一端を支軸8aで枢着された支持腕8が、容器7の下面を支えるようになっており、同支持腕8を90°まわすことにより容器7が取り出せるようになっている。
【0025】
また、通孔6は棚部材4上の実験用機器類5を拘束するためのベルト9の先端止具10のための係止溝を兼ねており、図6に示すように先端止具10の下端部10aが通孔6を経由して降下した後、鉛直軸まわりの90°の旋回により、先端止具10の狭隘部10bが通孔6の縁部に係合して存在する状態で、先端止具10の係止が行なわれるようになっている。
【0026】
さらに、図4〜6に示すように、棚部材4の周縁に沿い、同棚部材4の上面における実験用機器類5から流出した液体を堰止めうる液密のフェンス11が立設されている。
【0027】
このフェンス11には、図5に示すダクト部材12や図7に示す小物入れ13などが、それぞれフック部12a,13aを介し水平状態で引掛けられるようになっており、特にダクト部材12は実験用機器類5に接続された電源ケーブルや信号ケーブル類14の余長中間条体部14aを収容しうるようになっているほか、同余長中間条体部14aの出入を許容しうる複数の窓穴12bが形成されている。そして、ダクト部材12の側面には着脱可能のプラスチック製カバー12cが取り付けられており、同カバー12cの着脱はダクト部材12の端面を示す図8から明らかなように、弾性的に行なわれるようになっている。なお、図5における符号15はOAタップを示す。
【0028】
上述の本実施形態の実験では、地震などに際して、実験用機器類5を載置する棚部材4の上面に、同棚部材4上の実験用機器類5から可撓チューブ類14pが外れて薬液などの液体が漏出した場合に、同棚部材4の上面に形成された通孔6を通じて上記の漏出した液体が流下し、同棚部材4の下側に装着された容器7で受止められるので、同液体が棚部材4の下方に設置された他の実験用機器類を損傷させるのを十分に防止することができる。
【0029】
また、通孔6に実験用機器類5を拘束するベルト9の先端止具10が係止されるようになっているので、通孔6が漏洩液体の集液孔とベルト先端止具10の係止孔とを兼ねることになり、構造の簡素化がもたらされるようになる。
【0030】
さらに、棚部材4の周縁に沿い、同棚部材4上に流出した漏洩液体を堰止める液密のフェンス11が立設されているので、上記漏洩液体が前記の通孔6に入りきれずに棚部材4の上面に沿い流出して下方へ垂れ落ちるのを十分に防止することができる。
【0031】
また、実験用機器類5に接続された電源ケーブルや信号ケーブル類14の余長中間条体部14aを収容しうるダクト部材12が、フック部12aを介し水平状態でフェンス11に引掛けられるようになっているので、従来、実験台1の裏側などにもつれ込んでいた電源ケーブルなどの余長中間条体部14aが整理されるようになって、実験用機器類5の入換え作業などが大幅に簡便化されるようになる。
【0032】
さらに、ダクト部材12の壁部に、余長中間条体部14aの出入を許容する複数の窓穴12bが形成されているので、実験用機器類5に接続された電源ケーブルや信号ケーブル類14の配置および処理操作が、無駄なく適切に行なわれるようになる。またダクト部材12の側面にカバー12cが着脱自在に設けられているので、ケーブル類の余長中間条体部14aの処理操作が一層簡便化される。
【0033】
なお、上述の実施形態では通孔6が細長い溝穴状に形成されているが、棚部材4の上面に多数の偏平な円錐状の凹みを形成して、各凹みの中央部に通孔6を形成するようにしてもよく、この場合は各通孔6に共通の偏平な容器7が設けられる。
【0034】
次に本発明の他の実施形態について説明すると、図9は図4の要部の変形例を示すもので、この変形例では、容器7の底部に、下方へ突出したパイプ状の排液口7aが設けられ、この排液口7aには、図10(図9のD矢視図)に示すように排液管としてのチューブ16が着脱可能に装着されて、同チューブ16の下端部はプラスチック製の持ち運び式下部容器20の内部に挿入されるようになっている。
【0035】
また、図9に示すように、棚部材4のフェンス11は、棚部材4の上面4aを形成する板材の曲げ加工により、同棚部材4の上面4aと一体に形成され、同フェンス11の内側面11aが棚部材4の上面4aに対し鈍角をなすように傾斜するとともに、同フェンス11の外側面11bがほぼ鉛直面をなすように形成されている。
【0036】
さらに、上述の棚部材4の上面4aには、図11,図12および図13に示すように、棚部材4上の高速液体クロマトグラフィーによる分析実験用機器類5に接続された液体流通用チューブ5aを通過させて下方へ延在させるための小孔4bが形成され、同小孔4bの内周縁とチューブ5aの外周面との間を液密に塞ぐゴム製またはプラスチック製のリング状パッキン18が設けられている。そして、チューブ5aの下端部は、他の下部容器20aに挿入される。
【0037】
なお、実験台1の天板1aにもチューブ5aを挿通させるように図14に示すごとく小孔19が形成され、図15に示すように、この小孔19の内周に摩擦係合するプラスチック製のリング19aと、同リング19aに嵌め込まれて複数のチューブの相互間を分離するスペーサ19bとが設けられている。そして、スペーサ19bにはチューブを挿入する凹溝19cが形成されている。
【0038】
上述のように、棚部材下側の容器7の底部に排液口7aを形成して、同排液口7aに接続された排液チューブ16を介し下部容器20に排液を受ける構成になっていると、下部容器20の交換だけで排液の処理が著しく容易に行われるようになり、棚部材下側の容器7をいちいち取外さなくてすむ利点が得られる。
【0039】
さらに、棚部材4の周縁に設けられるフェンス11が、棚部材4の上面4aを形成する板材の曲げ加工により同棚部材4の上面4aと一体に構成されて、同フェンス11の内側面11aが棚部材4の上面4aに対し鈍角をなす傾斜面として形成され、同フェンス11の外側面11bがほぼ鉛直面をなすように形成されているので、フェンス11の剛性が増して強度上有利になるとともに、液漏れを起こすことが無く、製作時の工程が絞り加工などにより簡易化されるようになり、またフェンス11に膨らみをもたせることができるので、見栄えも向上する。
【0040】
また、棚部材4の上面4aに、同棚部材4上の液体クロマトグラフィーによる分析などのための実験用機器類から下方へ延在する液体流通用チューブ5aを通過させるようにした小孔4bが形成されて、同小孔4bの内周縁とチューブ5aの外周面との間を密封するリング状パッキン18が設けられるので、液体処理を伴う実験用機器類5の棚部材4上への搭載が支障なく行われ、しかも棚部材上面4aへの液体漏洩事故が生じてもパッキン18により棚部材4から下方への液体漏洩は防止され、漏洩液は棚部材4に形成された前述の液体導入用通孔6を介し同通孔6の下方の容器7に安全に受け入れられるようになる。なお、図16は図4の他の変形例を示しており、この実験の例では、図11における小孔4bに相当したチューブ5aのための通孔他の通孔6とが共に棚部材上面4aに形成されている。
【0041】
