Description

【０００１】
【発明の属する技術分野】
本発明は、電気電子機器用筐体の４隅に配置する電気電子機器用筐体のフレーム脚に関するものである。
【０００２】
【従来の技術】
従来の電気電子機器用筐体のフレーム脚は、図６に示すような４角枠上の中空断面形状からなるものや、図７に示すような断面コ字状のフレーム本体１０１に水切り枠部１０２を設けたものが普通であった。これらのフレーム脚にあっては筐体の４隅に配置した場合に同一のフレーム構造しかとれず、構造の異なる筐体を提供できないものであった。
【０００３】
【発明が解決しようとする課題】
本発明は前記のような従来の問題点を解決して、同一のフレーム脚を筐体の４隅に向きを変えて配置することにより２種類の構造の異なる筐体を製造できるフレーム脚を提供するためになされたものである。
【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電気電子機器用筐体のフレーム脚は、四角枠状とした中空フレーム本体の一角部に水切り枠部を設けるとともに、該一角部と対角線上に対向する角部に前記水切り枠部と対称する箇所に突出部を設けたフレーム脚を筐体の４隅に向きを変えて配置することにより２種類の異なる筐体を製造できることを特徴とするものである。また、水切り枠部と突出部を設けた以外の角部のうち少なくとも１の角部を内側に向かってくぼませることが好ましい。
【０００５】
【発明の実施の形態】
次に、本発明の好ましい実施の形態を図面に基づき説明する。
１は第１脚辺部１１と第３脚辺部１３を対向させ、該第１脚辺部１１と第３脚辺部１３の両端間に第２脚辺部１２と第４脚辺部１４を対向させてなる四角枠状の中空フレーム本体であり、該中空フレーム本体１の一角部即ち第１脚辺部１１と第４脚辺部１４との角部に第１脚辺部１１から張設した延長板部２１と該延長板部２１の先端に第４脚辺部１４と平行に形成した折曲片部２２により形成した水切り枠部２が設けられている。また、中空フレーム本体１の一角部と対角線上に対向した角部即ち第２脚辺部１２と第３脚辺部１３との角部に第３脚辺部１１から張設して突出部３が前記水切り枠部２と対称する箇所に設けられている。
【０００６】
このような本発明のフレーム脚は、図１に示すものは、第１脚辺部１１の一端に続けて延長板部２１を張設し、該延長板部２１の先端に内側に９０°向けて折曲片部２２を形成して水切り枠部２を設けて該折曲片部２２の先端縁を折り返すとともに、該第１脚辺部１１の他端に９０°折曲させて第２脚辺部１２を連設して該第２脚辺部１２の先端に外側に９０°折曲させて張出板部３１を連設して該張出板部３１の先端縁を外向きに折り返して連設した折返板部３２と重合させて突出部３を形成し、また、折返板部３２に続けて第３脚辺部１３に形成し、該第３脚辺部１３の先端に内向きに９０°折曲させて第４脚辺部１４を連設したうえ該第４脚辺部１４の先端に外向きに９０°折曲させて連結板部２１ａを連設して、該連結板部２１ａを前記延長板部２１に張り合わせてなり、１枚の鋼板をヘミング加工して形成したものである。
【０００７】
また、図２に示すフレーム脚は、第１脚辺部１１の一端に続けて延長板部２１を張設し、該延長板部２１の先端に内側に９０°向けて折曲片部２２を形成して水切り枠部２を設け、該第１脚辺部１１の他端に９０°折曲させて第２脚辺部１２を連設して該第２脚辺部１２の先端に外側に９０°折曲させ張出板部３１を連設してなる第１折曲鋼板（Ａ）と、第３脚辺部１３に先端に内向きに９０°折曲させて第４脚辺部１４を連設したうえ該第３脚辺部１３の基端に張出板部３２を連設し、また、第４脚辺部１４の先端に外向きに９０°折曲させて連結板部２１ａを連設してなる第２折曲鋼板（Ｂ）とを、延長板部２１と連結板部２１ａ、張出板部３１と張出板部３２とを張り合わせて形成したもので、２枚の鋼板を折曲したうえ張り合わせて製造したものである。
【０００８】
このように構成された本発明の電気電子機器用筐体のフレーム脚の４本を図３に示すように、前面左側に配置するフレーム脚は図１、２に示す状態で、前面右側に配置するフレーム脚は図１、２に示す状態から左右方向に反転させた状態で配置して、それぞれ対向させて四角枠状の中空フレーム本体１の一角部に設けた水切り枠部２が前面内側に位置させる共に突出部３を両側外面に添うように立設する。また、後面両側に配置する２本のフレーム脚は前記前面両側に配置した２本のフレーム脚を前後方向に反転した状態で対称となるように水切り枠部２が後面内側に位置させる共に突出部３を両側外面に添うように立設する。このように配置したうえ、側板４、４を両側の外面に面した第３脚辺部１３の外面及び突出部３に添装するとともに該側板４の両側に内向きに折曲形成した側枠部４ａ、４ａを第４脚辺部１４の外面に当接させて取り付ける。そして、水切り枠部２を囲装する周枠５ａ付きの扉５を前面に取り付け、また、後面に扉５或いは背面板を取り付ければ、水切り枠部２により扉５のシール性が優れた電気電子機器用筐体が提供できる。勿論、フレーム脚に当接する側板４、４、扉５、５の必要箇所には図示をしないがパッキンが設けられている。
【０００９】
また、図４に示すように各フレーム脚を前記図３の状態から各フレーム脚をそれぞれ前後方向に反転して配置すれば、各フレーム脚の第４脚辺部１４が側面の前後に対向するものとなるので、側板４、４の両側に内向きに折曲形成した側枠部４ａ、４ａの外面を第４脚辺部１４の外面に当接さて取り付ける。そして、前面及び後面に突出部３と中空フレーム本体１の第２脚辺部１２とによる受段部７を形成されているので、前面に扉５を嵌合するように取り付け、また、後面に扉５或いは背面板を嵌合して取り付けてれば、扉５、背面板が筐体から突出することがないすっきりした外観の筐体が提供できる。
【００１０】
なお、上記した実施形態では各フレーム脚は中空フレーム本体１を完全なる四角枠状のものにより説明したが、図５に示したように水切り枠部２と突出部３を設けた以外の２箇所の角部即ち第１脚辺部１１と第２脚辺部１２との角部と、第３脚辺部１３と第４脚辺部１４との角部のうち少なくとも一方の角部を内側に向かってくぼませてＬ字状取付面１ａを形成して該Ｌ字状取付面１ａに機器取付用の孔列１ｂを設けてもよい。また、中空フレーム本体１は四角枠状に限定されるものではなく多角形や前記のようなくぼませた角部を備えたものであってもよい。
【００１１】
【発明の効果】
以上に説明したように、本発明の電気電子機器用筐体のフレーム脚は、四角枠状の中空フレーム本体の一角部に水切り枠部を設けるとともに、該一角部と対角線上に対向する角部に前記水切り枠部と対称させて突出部を設けたものであるか、反転させて使用することにより２種類の異なったタイプの電気電子機器用筐体を提供できる。
従って、従来の電気電子機器用筐体のフレーム脚の問題点を解決したものとして業界にもたらす益大なものである。
