【発明の属する技術分野】
本発明は、棚付き実験台における実験器具の支持装置に係わり、更に詳しくは例えば机の背後又は机天板上に試薬棚等の収納棚を立設した棚付き実験台で、机天板上で使用する実験器具を保持するための支持杆を収納棚に取付けてなる支持装置に関する。
【０００２】
【従来の技術】
従来の棚付き実験台における実験器具の支持装置は、支持杆の基端部に、取付板を該支持杆の長手方向に対して平行又は直角に溶接したものを用い、該取付板を収納棚の前側支柱の側面又は前面にネジ止めして取付け、複数の支持杆を収納棚から前方へ突出させ、該支持杆の先端部に複数の取付杆を縦横に連結した、いわゆるスタッチーフを構成していた。
【０００３】
しかし、前記収納棚に対する支持杆の取付構造は、収納棚の支柱を利用してネジ止めした固定式であるため、支持杆の取付位置に対する自由度が少なく、支持する実験器具が少ない場合でも、収納棚の全面にスタッチーフが設けられることになり、机天板上のスペースの有効利用が図れない。つまり、収納棚の前面の一部のみにスタッチーフを設けることは不可能であった。
【０００４】
更に、収納棚に対する支持杆の突出長さも固定的であるため、支持する実験器具の大きさや種類に応じて支持杆を最適な突出長さに設定することも不可能であった。
【０００５】
【発明が解決しようとする課題】
本発明が前述の状況に鑑み、解決しようとするところは、机の背後又は机天板上に収納棚を立設した棚付き実験台において、机天板上で使用する実験器具を保持するための支持杆を収納棚に取付けてなる支持装置において、収納棚の横方向で任意の位置に支持杆を確実に取付けることができるとともに、収納棚に対する支持杆の突出長さを簡単に調節することが可能である棚付き実験台における実験器具の支持装置を提供する点にある。
【０００６】

【０００７】
ここで、前記装着部が、前記棚板下面に設けた支持レール又は棚板自体に形成したレール状凹溝又は棚板の前框と前後中間下面に突設した横補強部材又は棚板下面に沿って設けた排気ダクトの前縁部であることが好ましい。

更に具体的には、前記装着部が、前記棚板の前框と前後中間下面に突設した横補強部材であり、前記前框は前面板の下縁から後方へ延びた下片と該下片の後縁から上方へ延びた立片とを有するとともに、前記横補強部材は前記前框の後方で間隔を隔てた位置に前記下片と略面一の下面板を有し、前記取付具は、略水平な基板の前後縁に折曲板をそれぞれ上向き折曲するとともに、前側折曲板の上縁に前記前框の立片に係止する係止片を折曲形成し且つ前側折曲板に前記支持杆を遊挿する大径孔を形成し、前記前框と横補強部材間に位置する後側折曲板に前記支持杆を嵌挿する小径孔を形成し、前記基板に下方より螺合した締付ネジの先端で前記支持杆を押圧し、該支持杆を前記前框の下片と横補強部材の下面板に圧接してなるものである。
【０００９】
あるいは、前記装着部が、棚板下面に沿って設けた排気ダクトの前縁部であり、該排気ダクトの前縁部は底板の前縁から上方へ延びた前板を有し且つ該前板の前縁から後方へ延びた補強縁を有し、前記取付具は、略水平な基板の前後縁に折曲板をそれぞれ上向き折曲するとともに、前記排気ダクトの前板に沿って上方へ延びた前側折曲板の上縁に前記補強縁に係止する係止部を折曲形成し且つ前側折曲板に前記支持杆を遊挿する大径孔を形成し、前記排気ダクトの底板に向けて延びた後側折曲板に前記支持杆を上端が突出状態で嵌挿する切欠孔を形成し、前記基板に下方より螺合した締付ネジの先端で前記支持杆を押圧し、該支持杆を前記排気ダクトの底板に圧接してなるものである。

本発明の実験器具の支持装置は、前記収納棚２に沿って横方向に延びる装着部３を設け、該装着部３の適所に取付具４を装着するとともに、該取付具４に前後方向に突出長さを調節可能に前記支持杆５を取付けたものであり、収納棚２から前方に突出した複数の前記支持杆５，…を利用し、その先端部に複数の取付杆１１，…を取付けてスタッチーフを構成するのである。前記取付杆１１には、フラスコや管部材等の実験器具を取付け、各種の実験、試験を行えるようになっている。
【００１３】
前記収納棚２に沿って横方向に設けた前記装着部３としては、図２、図３及び図５に示すように、前記棚板７の前框１２と前後中間下面に突設した横補強部材１３をそのまま利用し、第１取付具４Ａにて支持杆５を取付けるもの、又は図２、図４及び図６に示すように、前記棚板７の下面に沿って設けた排気ダクト９の前縁部１４を利用し、該前縁部１４に第２取付具４Ｂにて支持杆５を取付けるものが、棚板７等に何ら設計変更を施すことなく既存の構造をそのまま装着部３として利用できるので好ましい。尚、後述のように、前記棚板７の下面に設けた支持レール又は棚板自体に形成したレール状凹溝を装着部３とすることも可能である。

【００１５】
そして、図３に示すように、前記第１取付具４Ａの係止片２２を棚板７の前框１２の立片１７に背面側から係止し、前記締付ネジ２７を緩めた状態で、前記支持杆５を前記第１取付具４Ａの大径孔２３に遊挿するとともに、小径孔２４に嵌挿して前框１２の下片１６と横補強部材１３の下面板１８に沿わせた後、前記締付ネジ２７を締付けてその先端で前記支持杆５を押圧し、該支持杆５を前記前框１２の下片１６と横補強部材１３の下面板１８に圧接して固定するのである。この場合、前記第１取付具４Ａを装着する位置は、棚板７の横方向に沿って任意に設定することが可能であり、また収納棚２に対する支持杆５の突出長さは、前記締付ネジ２７を締付ける前に第１取付具４Ａの大径孔２３と小径孔２４に対する挿入深さにより調節することが可能である。即ち、一つの締付ネジ２７によって、支持杆５を第１取付具４Ａを介して簡単に棚板７に固定することができる。また、前記第１取付具４Ａの前側折曲板２０と係止片２２とは、前記前框１２の立片１７に沿って接合しているので、第１取付具４Ａは横方向の捩じれに対して強固である。

そして、図４に示すように、前記第２取付具４Ｂの係止部３４を排気ダクト９の前縁部１４の補強縁３０に前面側から係止し、前記締付ネジ３９を緩めた状態で、前記支持杆５を前記第２取付具４Ｂの大径孔３５に遊挿するとともに、切欠孔３６に嵌挿して排気ダクト９の底板２８に沿わせた後、前記締付ネジ３９を締付けてその先端で前記支持杆５を押圧し、該支持杆５を前記排気ダクト９の底板２８に圧接して固定するのである。この場合、前記第２取付具４Ｂを装着する位置は、排気ダクト９の横方向に沿って任意に設定することが可能であり、また収納棚２に対する支持杆５の突出長さは、前記締付ネジ３９を締付ける前に第２取付具４Ｂの大径孔３５と切欠孔３６に対する挿入深さにより調節することが可能である。
【００１８】
尚、図７に示すように、中段の棚板７の下面に沿って排気ダクト９を設けない場合には、中段の棚板７にも前記第１取付具４Ａを用いて同様に支持杆５を取付けることが可能である。
【００１９】
また、図８及び図９に示した他の実施形態は、前記装着部３として、前記棚板７の下面に横方向に、断面略Ｃ字形のチャンネル部材からなる支持レール４０を取付けたものである。そして、前記支持レール４０に取付ける第３取付具４Ｃは、一対の同形の取付金具４１，４１からなり、該取付金具４１は、中央部に前記支持杆５の半周部を嵌合する半円筒状の嵌合部４２を形成するとともに、上端部に前記支持レール４０の開口縁４３，４３に９０°回転させて係合する切欠凹部４４，４４を形成し、また下端部に通孔４５を形成したものであり、一対の前記取付金具４１，４１を支持レール４０に係合した状態で、両嵌合部４２，４２間に前記支持杆５を挟み、前記通孔４５，４５に挿通したボルト４６とナット４７で締付けて固定する構造である。

A support device for attaching a supporting rod for holding a laboratory instrument to a storage shelf, provided with a mounting portion extending in a lateral direction along the storage shelf, and mounting the mounting tool at an appropriate position of the mounting portion Since the support rod is attached to the fixture so that the protruding length can be adjusted in the front-rear direction, the flexibility of the mounting position of the support rod in the lateral direction of the front surface of the storage shelf is large, so the entire front surface of the storage shelf or When only a part of the stool is supported and there are few experimental instruments to support, the space on the tabletop can be effectively used. Moreover, since the protrusion length of the support rod with respect to the storage shelf can be adjusted, the protrusion length can be optimally set from the storage shelf according to the laboratory equipment, and thus the space on the tabletop can be effectively used.
[0022]
According to the second aspect, the fixture can be easily moved to a desired position along the mounting portion newly provided on the lower surface of the shelf board or the mounting portion using the existing structure.
[0023]
According to the third aspect, the support rod can be securely attached to an arbitrary position in the lateral direction of the storage shelf, the protruding length of the support rod relative to the storage shelf can be easily adjusted, and the existing shelf Using the structure of the front plate of the plate and the lateral reinforcing member, the support rod can be firmly attached via a fixture with a single fastening screw.
[0024]
According to the fourth aspect of the present invention, the support rod can be reliably attached to an arbitrary position in the lateral direction of the storage shelf, the protruding length of the support rod relative to the storage shelf can be easily adjusted, and the existing exhaust Using the structure of the front edge portion of the duct, the support rod can be firmly attached via a fixture with a single fastening screw.
