Description

【０００１】
【発明の属する技術分野】
本発明は、収納棚の物品落下防止装置に係わり、更に詳しくは例えば試薬棚の棚板に載置した試薬品瓶等の物品が地震の震動又は誤って手に当てたり若しくは持ち損ねたりして落下することを防止するための収納棚の物品落下防止装置に関する。
【０００２】
【従来の技術】
従来の収納棚の物品落下防止装置は、棚板を支持する支柱の対向面間に落下防止バーを渡設したものであり、棚板上面は支柱の間隔を単位として装着した落下防止バーで区画されていた。
【０００３】
例えば、実公昭５８−４７８９８号公報にて開示される如く、支柱の係止孔に嵌入するカギ状脚を突設したブラケットに、入口部が狭く奥が巾広く形成された溝を側部に穿設し、前記溝に嵌入係止し得る連結杆を頭部に有し且つ尾部に筒体を有するロッドホルダーと、ロッドとを組み合わせた棚枠が記載されている。
【０００４】
しかし、前記落下防止バーや公報記載のロッドを支柱の係止孔を利用して棚板上方に横設する場合、落下の危険性のある物品が少ないにも係わらず、それによって区画される領域が棚板全面となって、不必要な部分にも落下防止バーが存在するので、棚板の一部を他の用途の収納スペースとして利用できないといった欠点があった。
【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、落下防止バーを前記棚板上方に横設して、収納棚の棚板に載置した物品の落下を防止することが可能であるとともに、落下防止バーの取付位置と組合せに自由度があり、棚板上面の必要な部分にのみ落下防止バーで区画した領域を作ることが可能な収納棚の物品落下防止装置を提供する点にある。
【０００６】
【課題を解決するための手段】
本発明は、前述の課題解決のために、収納棚の棚板に載置した物品の落下を防止すべく、棚板上面又は該棚板を支持する支柱の内側面にブロック状の支持具を複数個着脱自在に取付け、前記支持具に落下防止バーの端部又は中間部を保持して前記棚板上方に横設してなる収納棚の物品落下防止装置であって、前記支持具に第１取付手段を備えるとともに、前記棚板又は支柱に前記第１取付手段によって支持具を取付ける第２取付手段を複数箇所に設け、前記支持具は、本体に対して分割体を着脱自在となしたものであり、前記分割体には落下防止バーを嵌合する凹溝からなる第１係合部を形成し、前記本体には落下防止バーを嵌合する凹溝からなる第２係合部を形成し、前記本体に分割体を合体して第１係合部と第２係合部の溝方向を互いに直交させて設けてなる収納棚の物品落下防止装置を構成した。
【０００７】
ここで、前記本体には、前記第２係合部の側部に前記分割体を合体させる凹部を形成し、該凹部の底面部に前記第２係合部の溝方向に直交したアリを形成し、前記分割体の底面で第１係合部の溝方向に沿ってアリ溝を形成し、前記アリとアリ溝のスライド係合によって前記支持具を構成し、もって第１係合部と第２係合部とを直交状態となした。また、前記第２係合部の両端開放した凹溝内に、該凹溝の長さよりも十分に厚さの薄い仕切部材を着脱自在に取付け、前記凹溝を閉鎖可能としてなることがより好ましい。
【０００８】
また、本発明は、収納棚の棚板に載置した物品の落下を防止すべく、棚板上面又は該棚板を支持する支柱の内側面にブロック状の支持具を複数個着脱自在に取付け、前記支持具に落下防止バーの端部又は中間部を保持して前記棚板上方に横設してなる収納棚の物品落下防止装置であって、前記支持具に第１取付手段を備えるとともに、前記棚板又は支柱に前記第１取付手段によって支持具を取付ける第２取付手段を複数箇所に設け、前記支持具には落下防止バーを嵌合する第１係合部と第２係合部を互いに直交させて形成し、前記第１係合部は一端を閉鎖した凹溝であり、前記第２係合部は両端開放した凹溝であり、前記第２係合部の凹溝内に、該凹溝の長さよりも十分に厚さの薄い仕切部材を着脱自在に取付け、前記凹溝を閉鎖可能としてなる収納棚の物品落下防止装置を構成した。
【０００９】
【発明の実施の形態】
次に本発明の実施形態を添付図面に基づき更に詳細に説明する。図１は本発明に係る収納棚の物品落下防止装置を適用した実験台を示し、図２はその要部を示し、図３〜図６は本発明の第１実施形態を示し、図中符号１は実験台、２は実験台１を構成する机、３は実験台１を構成する収納棚、４は支持具、５は落下防止バーをそれぞれ示している。
【００１０】
前記実験台１は、机２の背面に収納棚３を立設したものである。前記収納棚３は、前後左右に４本の支柱６，…立設するとともに、左右の支柱６，６間に複数の棚板７，７を多段に設けるとともに、上端部に天板８と下端に地板９を設けたものであり、下段の棚板７は前記机２の机天板１０と高さを一致させている。また、前側の前記支柱６，６の前面であって机天板１０よりも上位には、多数のコンセント１１，…を内蔵し、各種の計測機器やパソコン等を使用できるようになっている。また、前記上段の棚板７には、試薬品瓶等の物品を収納するために、複数の支持具４，…を棚板７の上面に着脱自在に取付けて、該支持具４，…を利用して落下防止バー５を棚板７上方に渡設して、当該棚板７の上面を区画している。
【００１１】
更に詳しくは、前記支持具４は、合成樹脂製でブロック状に成形したものであり、前記棚板７又は支柱６への第１取付手段１２を備えるとともに、円柱状又は円筒状の前記落下防止バー５を嵌合する第１係合部１３と第２係合部１４を互いに直交させて形成したものである。ここで、前記第１係合部１３は一端を閉鎖した凹溝１５であり、前記第２係合部１４は一端を閉鎖又は両端開放した凹溝１６である。
【００１２】
ここで、本実施形態では、前記第２係合部１４は、両端開放した凹溝１６を有するものであり、該凹溝１６内に、該凹溝１６の長さよりも十分に厚さの薄い仕切部材１７（図３及び図６参照）を着脱自在に内嵌し、前記凹溝１６を閉鎖可能としている。尚、前記凹溝１６の底部に沿ってアリ１８を形成するとともに、前記仕切部材１７の底面にアリ溝１９を形成し、前記アリ１８とアリ溝１９との係合によって仕切部材１７を凹溝１６に沿って正確にスライド移動可能としている。それにより、前記凹溝１６の溝方向へ仕切部材１７を任意に移動させ、その状態で保持することが可能である。つまり、前記仕切部材１７を凹溝１６の溝方向の中央部又は両端部に位置させることが可能である。
【００１３】
また、図３に示すように、本実施形態では、前記支持具４の本体４Ａ（図４参照）に対して前記第１係合部１３となる凹溝１５を設けた分割体４Ｂ（図５参照）を着脱自在となしている。つまり、前記本体４Ａには、前記第２係合部１４の側部に前記分割体４Ｂを合体させる凹部２０を形成しておき、該凹部２０の底面部に前記第２係合部１４の溝方向に直交したアリ２１を形成し、前記分割体４Ｂの底面で第１係合部１３の溝方向に沿ってアリ溝２２を形成し、前記アリ２１とアリ溝２２のスライド係合によって支持具４を構成し、もって第１係合部１３と第２係合部１４とを直交状態となすのである。ここで、前記分割体４Ｂに形成した凹溝１５は、両端が開放した溝であるが、本体４Ａに合体させた場合にはその凹溝１５の一端は第２係合部１４の側面によって閉鎖されるのである。また、前記仕切部材１７は、使用しない場合には、前記本体４Ａの内部に設けた開口部２３を形成し、該開口部２３の底面に前記アリ溝１９を係合するアリ２４を突設し、該仕切部材１７を開口部２３内に格納するとともに、アリ２４にアリ溝１９を係合させて保持している。
【００１４】
また、本実施形態では、前記第１係合部１３の凹溝１５の開口縁部には落下防止バー５を嵌入して抜止めするための突縁２５，２５を凹溝１５内に突設し、また前記第２係合部１４の凹溝１６の開口縁部にも同様に突縁２６，２６を形成している。
【００１５】
また、本実施形態では、前記第１取付手段１２は、本体４Ａの下面に突設した偏平円柱状の首部２７と、その下端に前記首部２７の直径よりも長径が大きい長円形の頭部２８とを一体形成したものとし、前記棚板７の上面には、前記第１取付手段１２によって支持具４を取付ける第２取付手段を複数箇所に設けている。つまり、前記棚板７に設けた第２取付手段は、該棚板７の四隅と前後縁に沿って所定間隔毎に形成した係合孔２９，…であり、該係合孔２９は前記首部２７と頭部２８の平面視外形よりも相似的に大きい形状を有し、該係合孔２９に前記第１取付手段１２の頭部２８と首部２７を挿入後、９０°回転させて頭部２８を係止して抜止めする。尚、前記支持具４の各第１係合部１３及び第２係合部１４に落下防止バー５を嵌合した後には、当該支持具４は回転しないので、頭部２８が係合孔２９から抜けることがないのである。
【００１６】
本実施形態では、前記支持具４の取付ける向きは、第１係合部１３の溝方向を棚板７の奥行方向に設定し、第２係合部１４の溝方向を棚板７の横方向、即ち間口方向に設定し、棚板７の前縁に取付ける支持具４の第１係合部１３の閉鎖端を前側に設定し、棚板７の後縁に取付ける支持具４の第１係合部１３の閉鎖端を後側に設定している。そして、前記棚板７の前後に取付けた支持具４，４の第１係合部１３，１３に奥行方向に配した落下防止バー５の両端を嵌合し、また前縁又は後縁に設けた両支持具４，４の第２係合部１４，１４に間口方向に配した落下防止バー５の両端を嵌合している。尚、間口方向に配した落下防止バー５の端部に対応する支持具４の第２係合部１４には、該落下防止バー５の端部を隠すために前記仕切部材１７を凹溝１６内に嵌合している。また、落下防止バー５が長尺の場合には、中間の所定位置に取付け支持具４の第２係合部１４に落下防止バー５の中間部を嵌合し、また不要な分割体４Ｂを本体４Ａから外している。
【００１７】
このように、棚板７の前後縁に一定間隔で多数の係合孔２９，…を形成しておけば、前記係合孔２９の間隔を最小単位として落下防止バー５，…で区画することができ、この落下防止バー５，…で囲まれた領域に落下の可能性のある物品を収納すれば良い。この落下防止バー５，…で囲まれた領域は、一枚の棚板７上に複数形成することも可能である。
【００１８】
次に、図７に示した第２実施形態は、第１係合部１３の一端を閉鎖するとともに、第２係合部１４の一端も閉鎖したものであり、支持具４に設ける前記第１取付手段１２として、棚板７の設けた螺孔３０，３０に、第１係合部１３と第２係合部１４のそれぞれの凹溝１５，１６の底部から支持具４の底面に貫通させた取付孔３１，３１に上方から挿通したネジ３２，３２を螺合して取付ける構造としたものである。ここで、前記取付孔３１，３１からなる第１取付手段１２によって支持具４をネジ３２，３２で棚板７に取付けるために、該棚板７に設けた第２取付手段が前記螺孔３０である。その他は第１実施形態と同様であるので、同一構成には同一符号を付してその説明は省略する。
【００１９】
次に、図８及び図９に示した第３実施形態は、支持具４を前記支柱６の内面側に棚板７を支持するために形成した係止孔３３，…を利用して支柱６の所定高さに取付けることができるようになしたものである。つまり、図９に示すように、支持具４の対向する両側面に二つの係合穴３４，３４を前記係止孔３３，３３のピッチに合わせて貫設し、該係合穴３４，３４に着脱自在にピン３５，３５を嵌合して側面から突設し、該ピン３５，３５を前記支柱６の対応する係止孔３３，３３に挿入して保持するのである。ここで、支持具４に第１取付手段１２として設けたピン３５，３５によって、該支持具４を支柱６に取付ける第２取付手段が前記係止孔３３，…である。そして、支柱６に取付けた支持具４と、第１又は２実施形態と同様に棚板７の上面に取付けた支持具４との間に落下防止バー５を渡設するのである。その他の構成は、前記同様であるので、同一構成には同一符号を付してその説明は省略する。
【００２０】
次に、図１０に示した第４実施形態は、支持具４を二分割金型で成形できるように第１係合部１３の構造を爪部を千鳥状に配したものとし、第２係合部１４の底部に溝方向に沿ってアリ溝３６を形成し、該凹溝１６内に嵌合する図示しない仕切部材１７にアリを形成すること以外は、前記同様であるので、同一構成には同一符号を付してその説明は省略する。
【００２１】
また、図１１に示した第５実施形態は、第３実施形態と同様に支柱６の係止孔３３を利用して取付けることができるものであり、両端が開放した第２係合部１４の凹溝１６の溝方向中央部に上下方向の係合溝３７，３７を形成し、該係合溝３７，３７に上方から単純な板状の仕切部材１７を着脱自在に嵌着できるようにしたものである。その他の構成は、第３実施形態と同様であるので、同一構成には同一符号を付してその説明は省略する。
【００２２】
そして、図１２に示した第６実施形態は、仕切部材１７の形状及び第２係合部１４への嵌合構造が第４実施形態と異なるものであり、即ち第２係合部１４の凹溝１６の底部に溝方向に沿ってアリ溝３８を形成するとともに、凹溝１６内に係合する形状を有する仕切部材１７の下端に前記アリ溝３８にスライド係合するやや嵌合方向に長いアリ３９を形成したものである。その他の構成は、第３実施形態と同様であるので、同一構成には同一符号を付してその説明は省略する。
【００２３】
以上のように、前記支持具４は、棚板７の上面又は支柱６の内側面に着脱自在に取付け、また棚板７の上面に取付けた他の支持具４との間に落下防止バー５を嵌着することによって、棚板７の上方に落下防止バー５を横設し、複数の該落下防止バー５，…で区画された領域を作ることが可能である。そして、落下防止バー５，…で囲まれた領域の棚板７の上面に載置した物品は、地震等の震動によって棚板７の縁部に移動しても、落下防止バー５で移動が規制されるので、簡単には落下しないのである。尚、本実施形態において、凹凸嵌合の構造をアリとアリ溝を用いたが、他の凹凸嵌合構造を採用することも可能である。
【００２４】
