Description

【０００１】
【発明の属する技術分野】
本発明は、電気・電子機器収納用ボックス等に換気用のファンを取り付けるためのボックスへのファン取付構造に関するものである。
【０００２】
【従来の技術】
従来のボックスへのファン取付構造は、図８に示すようにボックス１０１に設けたスリット状の放熱孔１０２の端部にスリット幅より大径のファン取付用の取付孔１０３を加工して、ボックス１０１の外側から該取付孔１０３にねじ１０４を挿通して放熱孔１０２の内面にファン１０５を取り付けるものが普通であった。
【０００３】
【発明が解決しようとする課題】
放熱孔１０２のみ加工してあるボックスでは、後加工で取付孔１０３を加工しなければならないので、塗装が剥離する。また、既設のものでは、内部機器であるブレーカ等が通電されている為、取付孔１０３の加工が非常に面倒であるという問題があった。
また、これを回避するため、予め取付孔１０３を設けてあるものでは、ファン１０５の取付位置が限定されてしまう。さらに、ファン１０５を取付ない場合は、外観が悪くなるという問題があった。
【０００４】
【課題を解決するための手段】
前記の課題を解決するためになされた本発明のボックスへのファン取付構造は、ボックスに多数配設したスリット状の放熱孔のうち任意に選択した放熱孔に取付金具を装着して、該取付金具にファンを取り付けたボックスへのファン取付構造において、前記取付金具を、基端に鍔板部を張設するとともに先端側に受金具嵌合用の切欠部を設けた偏平状の取付金具本体と、前記切欠部に嵌合される受金具部とよりなるものとしたものを請求項１に記載の発明とする。また、ボックスに多数配設したスリット状の放熱孔のうち任意に選択した放熱孔に取付金具を装着して、該取付金具にファンを取り付けたボックスへのファン取付構造において、前記取付金具を、主板部の基端に鍔板部を折曲形成するとともに先端側に雌ねじ部付き受金具部を前記鍔板部に対向させて一体に折曲形成したものとしたものを請求項２に記載の発明とする。
【０００５】
本発明によれば、ボックスに多数配設したスリット状の放熱孔のうち任意に選択したものに取付金具を装着して、該取付金具にファンを取り付けるものであるから、ファン取付用の孔をボックスに加工する必要がないものである。
【０００６】
【発明の実施の形態】
次に、本発明の好ましい実施の形態を示す。
図１〜図４は本発明の第1の実施形態を示すものである。
１は電気・電子機器収納用ボックス等のボックスであり、該ボックス１には放熱用のスリット状の放熱孔２が多数配設されている。３は前記放熱孔２のうち任意の例えば後記するファンベース７１の取付孔７１ａに合致する放熱孔に装着する取付金具である。この第1の実施形態の取付金具３は図３及び図4に示すように、基端に前記放熱孔２の孔縁に当接する鍔板部４１を張設するとともに先端側に受金具嵌合用の切欠部４２を設けた偏平状の取付金具本体４と、前記切欠部４２に嵌合される雌ねじ部５１付きの受金具５とよりなるものであり、取付金具本体４をスリット状の放熱孔２に挿通後に受金具５を該取付金具本体４の切欠部４２に嵌合して取り付けるものである。
【０００７】
このように構成されたものは、ボックス１に設けた多数配設したスリット状の放熱孔２のうち任意の例えばファンベース７１の４隅に配置した取付孔７１ａと合致するものに取付金具３を装着する。すなわち、取付金具３の偏平状の取付金具本体４をボックス１の表面側からスリット状の放熱孔２を挿通させて基端に張設した鍔板部４１を放熱孔２の表面側孔縁に当接させ、その後に取付金具本体４の先端側に設けた受金具嵌合用の切欠部４２に雌ねじ部５１付きの受金具５を嵌合する。
【０００８】
そして、前記したように取付金具３を放熱孔２に装着したら、ファンベース７１の４隅に配置した取付孔７１ａを取付金具３の受金具部５の雌ねじ部５１に合致させて、雄ネジ８を取付孔７１ａに挿通したうえ雌ねじ部５１に螺合してファンベース７１を取付金具３に取り付ける。その後にファンベース７１に取付ねじ７２によりファン本体７０及びファンカバー７３を取り付ければ、ファン７がボックス１の内側から取付金具３に取り付けられることとなる。
【０００９】
続いて、図５〜図７に示す本発明の第２の実施形態を説明する。
１は電気・電子機器収納用ボックス等のボックスであり、該ボックス１には放熱用のスリット状の放熱孔２が多数配設されているのは前記第１の実施形態と同様である。３は前記放熱孔２のうち任意の前記と同様にファンベース７１の取付孔７１ａに合致する放熱孔に装着する取付金具である。この第２の実施形態の取付金具３は図６に示すように、主板部４０の基端に鍔板部４１を折曲形成するとともに先端側に雌ねじ部５１付き受金具部５を前記鍔板部４１に対向させて一体に折曲形成したものである。
【００１０】
このように構成されたものは、ボックス１に設けた多数配設したスリット状の放熱孔２のうち任意の例えばファンベース７１の４隅に配置した取付孔７１ａと合致するものに取付金具３を装着する。すなわち、取付金具３の主板部４０の先端側に折曲形成した雌ねじ部５１付きの受金具部５をボックス１の表面側からスリット状の放熱孔２に挿通させて、次に主板部４０を該放熱孔２に挿通させて主板部４０の基端に張設した鍔板部４１を放熱孔２の表面側孔縁に当接させる。これにより取付金具３の受金具部５は雌ねじ５１を放熱孔２と同一面を向くものである。
【００１１】
そして、前記したように取付金具３を放熱孔２に装着したら、ファンベース７１の４隅に配置した取付孔７１ａを取付金具３の受金具部５の雌ねじ部５１に合致させて、雄ネジ８を取付孔７１ａに挿通したうえ雌ねじ部５１に螺合してファンベース７１を取付金具３に取り付ける。その後にファンベース７１に取付ねじ７２によりファン本体７０及びファンカバー７３を取り付ければ、ファン７がボックス１の内側から取付金具３に取り付けられることとなる。なお、取付金具３ががたつくことなく放熱孔２に装着できるようにボックス１の壁面と受金具部５との間に図７に示す断面コ字型の押え金具９を嵌着させておくことが好ましい。この場合に押え金具９に受金具部５に設けた小孔５２に係止する突起９１を設けて抜け出ることなくなく的確に嵌着できるものするとともに、受金具部５の雌ねじ部５１に螺合した雄ネジ８の先端部の逃げのためのねじ挿通孔９２が形成されている。
【００１２】
【発明の効果】
以上に説明したように、本発明のボックスへのファン取付構造は、ボックスに予め設けられているスリット状の放熱孔を利用して取付金具を装着して、該取付金具にファンを取り付けるものであるから、ボックスに取付金具を装着するための孔加工を不要とするものであり、その加工作業により塗装が剥離するという問題も生じないものである。また、既設のものに放熱孔が有れば簡単に取付ができる。さらに、放熱孔が有ればどこにでもファンの取付ができるので、内部機器の発熱を考慮した効率の良い位置にファンの取付でき、また、ファンの大きさが変わっても取付可能であり、さらに、ファンを取付けなくても外観が悪くなることもない。
よって、本発明は従来のボックスへのファン取付構造の問題点を解決したもので、業界にもたらす益大なものである。
