Description

【０００１】
【発明の属する技術分野】
本発明は、照明制御、動力制御等の配電機器を収納する電気機器収納箱に関するものである。
【０００２】
【従来の技術】
一般に、照明制御、動力制御等の配電機器を収納する電気機器収納箱においては、一面開口の箱本体が、比較的小型のものは板金を折り曲げて、その折曲げ形成された側板同士の接合部分を溶接して形成され、また、比較的大型のものはフレーム材に金属板による側板をねじ止めして形成されていた。
【０００３】
上記の箱本体には、その開口部に、板金製の扉体が開閉自在に枢着され、箱本体と同様に折曲げ、溶接加工にて形成された板金製の扉枠が設けられる。そしてその内方に、内器となる上記の電気機器等を固定するフレーム材等の内器固定部材と、電気機器への接続電線を覆うとともに電気機器の前面側を露出させる中蓋とが溶接、ねじ止め等により取付部材を介して固着されていた。
【０００４】
上記電気機器収納箱は、建物の躯体に設置する場合、まず箱本体を固定させ、次いで、その箱本体内方に電気機器を収容させた後、中蓋を取り付けて上記扉体を有する扉枠をその箱本体に装着させて施工される。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記従来の技術においては、箱本体や扉体等が主として板金材料の折曲げ及び溶接工程を経て形成される。そのため、強度的には頑丈であるものの、重量の大きいものとなって運搬上に問題があるとともに、その製作には多くの工程を要して手間のかかるものであった。また、縦横寸法のサイズ違いへの対応にも、複雑な外形形状で寸法の異なる板金部材の製作、あるいは、板金材料を折曲させた後、防錆のための塗装を行う必要もあって手間のかかるものであった。
【０００６】
ところで、上記の扉体は、多くの場合、ピン部材と同ピン部材の受け部材とにより構成される蝶番を介して扉枠に固着されており、したがって、その蝶番の溶接位置の精度確保のために手間がかかるという問題があった。また、その箱体への装着に際しては、上記扉枠とともに箱体へ固着させる必要があり、重量が大きいために設置作業のし辛いものであった。
【０００７】
本発明は、上記事由に鑑みてなしたもので、その目的とするところは、製作時の作業性に優れ、各種設計寸法のものへの対応が容易で製造コストを低く抑えることができ、また、扉体を簡単に箱本体へ着脱可能で容易に建物の躯体に設置することのできる電気機器収納箱を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために、本発明の電気機器収納箱にあっては、一縁部に底板係合溝の沿設された長尺平板材を押出成形し、所定長さに切断して左右側板及び上下側板を切り出し、底板と該左右側板及び上下側板とを前記底板係合溝にて係合させて一面開口の箱本体を構成するとともに、その開口を開閉自在となるよう、前記左右何れかの側板に扉体を枢着させてなる電気機器収納箱において、前記左右何れかの側板の他縁部に長手方向全長にわたる枢支部を沿設し、前記扉体を、その枢支部に対応する被枢支部を備えた押出成形による枠材を設けて枢着させたことを特徴としている。
【０００９】
なお、本発明は、建物の壁面へ取り付けられて、照明制御、動力制御等の配電機器を収納する電気機器収納箱に好適に適用することができる。また、上記長尺平板材は、アルミ材料による押出成形品により構成するのが好ましい。したがって、底板と押出成形材の左右側板及び上下側板とを底板係合溝にて係合させ構成するより、溶接作業が不要となって製作時の作業性が向上し、各種設計寸法のものへの対応が容易で製造コストを低く抑えることができる。
【００１０】
上記枢支部は押出成型時に同時に形成され、扉体が全長にわたってその枢支部にて枢支されて開閉されるので、蝶番を設けるときのように扉体と箱本体との間に隙間の生ずることがなく、以て、使用に際して箱本体内に塵埃等が侵入せず、また、その枢支部分が扉体の長手方向の大きさに対応させて構成され、扉体の重量変化に対応可能となる。
【００１１】
また、前記扉体を、少なくともパネル固着部を連設させた長尺平板材を押出成形し、所定長さに切断して左右枠材及び上下枠材を切り出し、扉パネルと該左右枠材及び上下枠材とを前記パネル固着部を介して一体化させ形成することができる。これによれば、扉体も各種設計寸法のものへの対応が容易となって、製造コストをより低く抑えることができる。
【００１２】
また、前記底板及び扉パネルを塗装付き板金材にて形成するとともに、前記側板及び枠材を、その底板係合溝及びパネル固着部に底板及び扉パネルが挿入されて周囲の破断面を覆うように形成することも好ましい。これによれば、塗装作業が不要となって製作時の作業性がより向上する。
【００１３】
また、前記箱本体及び／又は扉体は、その４隅に前記側板及び／又は枠材の相互を固定させる隅部材を有してなることも好ましい。この場合、隅部材を介して側板又は枠材の相互が固定されるので、縦横の接合作業を容易に行うことができ、また、隅部材にて箱本体及び扉体自体の強度も向上できる。さらに、前記扉パネルの周囲の対向する２辺又は４辺に、後方へ折曲させた補強片を設け、前記パネル固着部を同補強片に係合するように形成することができる。これにより、扉パネルが補強片にて補強されることとなって、扉体と箱本体との開閉を安定に行うことができる。
【００１４】
また、前記側板は、箱本体内方に収納する電気機器を固定させる内器固定部材を支持する内器支持片または内器支持溝を連設させることができる。これによれば、溶接等により内器固定部材を支持するための取付部材を設ける必要が無く、また、前記側板は、前記扉体の開状態にて箱本体内方に収納された電気機器の前面側を露出させる中蓋の縁部を支持する中蓋支持片または中蓋支持溝を連設させることもでき、これによると、溶接、ねじ止め等により中蓋支持部材を設ける必要も無く、溶接、ねじ止め等の作業追加による製造コストの上昇が回避される。
【００１５】
また、前記中蓋は、その下辺に前記中蓋支持片または中蓋支持溝に係合し支持される下支持部及び、その上部に、上方へ付勢されて前記中蓋支持片または中蓋支持溝に係合して中蓋自体を支持及び固着させる上支持部を有することが好ましい。この場合、中蓋自体をワンタッチにて支持及び固着させ着脱することができて、収納された電気機器のメンテナンス性に優れる。
【００１６】
また、前記側板は、前記扉体の閉状態にてその背面側に当接する扉止めリブが連設されていることが好ましい。これにより、扉止めリブに扉体自体を位置決めさせて閉止させることができて浮き沈みがなく、扉の閉状態の外観の美観において優れ、また、前記側板は、前記扉止めリブに、前記扉体に設けられた扉閉止具の扉閉止片を同扉体の閉状態にて回動又はスライドさせ当接させる扉閉止リブを並設することも好ましい。この場合、扉閉止具の扉閉止片を、扉止めリブに並設された扉閉止リブに当接させて扉体を閉止状態をすることができて、同様に外観の美観において優れる。
【００１７】
また、前記枢支部は、前記扉体が閉状態から箱本体の開口面と略垂直位置まで開閉可能で且つ同位置にて着脱自在となるよう前記被枢支部を枢着させる枢着片を有するとともに、扉体には、その被枢支部側上下に配設される隅部材に、その略垂直位置とした扉体の長手方向のスライド止め部材を配設させてなることが好ましい。これにより、枢支部の枢着片にて、扉体が略垂直位置まで開閉可能となるよう扉体が枢着され、また、扉体の長手方向の移動を止めるスライド止め部材にて止められるとともに該スライド止め部材の着脱にて箱本体から扉体が容易に着脱される。
【００１８】
また、前記スライド止め部材は、前記扉体を略垂直位置の開位置に位置決めする位置決め片を有し、同位置決め片を前記の上下各側板に設けられた扉止めリブに位置決めさせることも好ましい。この場合、扉体が、スライド止め部材の位置決め片にてその略垂直位置の開位置に位置決めされるので、さらに略垂直位置より以上に回動して箱本体から離脱することが無く使い勝手が良い。
【００１９】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図１乃至図１３は、本発明の請求項１乃至１３全てに係る一実施の形態の電気機器収納箱１を示しており、該電気機器収納箱１は、箱本体２と、扉体６と、中蓋１２とを備えている。
【００２０】
この電気機器収納箱１は、その一縁の端部に長手方向に延びる底板係合溝３４、他縁部に長手方向全長にわたる枢支部３５あるいは扉止めリブ３６がそれぞれ沿設され、また中間に中蓋支持片３７と内器支持溝３８，３８とが連設されたアルミ材料製の長尺平板材をそれぞれ押出成形し（図４参照）、所定長さに切断して左右側板３１，３２及び上下側板３３，３３を切り出し、該側板３１，３２、３３を、平板状の底板５と組み合わせることによって一面開口の箱本体２を構成している。そして、該箱本体２の左右側板３１又は３２に扉体６を枢着させ、上下側板３３，３３に中蓋１２を支持させ固着させてなるものである。
【００２１】
底板係合溝３４は、後述する底板５の厚さ寸法より僅かに大きい隙間幅を有し、内側となる溝構成用のリブの突出寸法を大きくなるようにして各側板の一縁部に形成されている。したがって、図４に示すように、底板係合溝３４に底板５を挿入させてその外側のリブを変形させ、底板５を底板係合溝３４に係合させてカシメを行うときに、直角の位置決めをより確実に行って箱本体２を形成することができる。
【００２２】
この場合、壁面へ取り付いた状態において右側となる側板３２の他縁部には、枢支部３５とともに箱本体２の化粧縁となる化粧リブ３９が内側に向けて延出し並設されている。この枢支部３５は、その先端が開口した断面略円状の枢支片３ａと、この枢支片３ａと同心状となるようその基端部分から所定角度にわたって弧状に延出された枢着片３ｂとを有してなる。したがって、後述する扉体６の被枢支部７５を枢支させて、その閉状態から箱本体２の開口面と略垂直位置まで開閉可能とさせるとともに、その略垂直位置にて着脱自在となるよう枢着させることができる。
【００２３】
また、壁面へ取り付いた状態において左側となる側板３１、及び上下の側板３３，３３の他縁部には、その基端部分が箱本体２の化粧縁となるよう段差をもって、後述する扉体６を閉状態にするときにその背面側に当接させる扉止めリブ３６が内側に向けて延出させ連設されており、また、この扉止めリブ３６の内側には扉閉止リブ３ｃが並設されている。この扉閉止リブ３ｃは、扉体６が扉止めリブ３６に閉状態にて、扉体６に設けられた扉閉止具１０の扉閉止片１０２が回動されて当接される。したがって、扉体６を扉止めリブ３６に位置決めさせて、ガタツキを少なくし、また浮き沈みの無い美観良い閉止状態とすることができる。
【００２４】
中蓋支持片３７は、後述する中蓋１２の縁部１２５を支持するためのもので、側板３１，３２，３３の中間となる所定位置に突出し連設されている。この中蓋支持片３７の基端には、箱本体２内方に収納される電気機器を固定させる内器固定部材（図示せず）の端部を支持するための二条の内器支持溝３８，３８の一方のものが設けられている。
【００２５】
この場合、底板５と後述する扉体６を構成する扉パネル９とは、所定色の塗料にて着色された塗装付き板金材にて形成されている。したがって、この底板５を上記底板係合溝３４に係合させカシメを行ったときに、底板５周囲の破断面が覆われるため、塗装作業を行うことなく錆防止が達成されて製作時の作業性をより向上させることができる。
【００２６】
上記の側板３１、３２、３３，３３と底板５とを組み合わせるときには、その４隅に側板相互を固定させる隅部材４をそれぞれ設けて組み合わせ作業がなされる。この隅部材４は、合成樹脂材料やアルミニウム材料にて、図５（ａ）、（ｃ）に示すように、側板３１、３２、３３，３３に設けられた各溝部分あるいはリブ間の隙間に対応するように被カシメ片４１が設けられて成形されている。そして、この隅部材４を介して側板３１、３２、３３，３３の相互が、図５（ｂ）、（ｄ）に示すように接合された後、図６（ａ）、（ｂ）に示すように、上記被カシメ片４１を介して固定される。したがって、縦横の接合作業を容易に行うことができ、また、隅部材４にて箱本体２自体の強度を向上できる。
【００２７】
上記箱本体２には、この場合、図２に示すような扉体６が装着される。この扉体６は、左右の枠材７１、７２及び上下の枠材７３，７３と、この枠材相互を固定させる４隅の隅部材８と、扉パネル９と、この扉パネル９を箱本体２へ閉止させる扉閉止具１０とを有している。そして、箱本体２に装着されて壁面へ取り付いた状態において右側となる枠材７２の上縁部には、被枢支部７５が形成されている。
【００２８】
この枠材７１、７２、７３，７３は長尺平板状で、アルミ材料にて形成されており、扉体６の化粧縁となる化粧リブ７６が一端の内側に向けて延出され、この化粧リブ７６とともに後述する扉パネル９の縁部を把持しカシメを行うためのカシメ片７４が連設されて内側となる一面にパネル固着部を構成している。また、化粧リブ７６は、外側となる他面側に向けても延出され、枠材７２においては、この化粧リブ７６がその一部となるよう被枢支部７５が形成されている。
【００２９】
被枢支部７５は、前記枢支片３ａの略円状とその内部にて係合するよう先端が開口した断面略円状の中空状で、図９（ａ）に示すように、この枢支片３ａ及びその外側に弧状に延出された枢着片３ｂとに枢支されて、図９（ｂ）に示すように、扉体６をその閉状態から箱本体２の開口面と略垂直位置まで開閉可能とさせて、図９（ｃ）に示すように、その略垂直位置にて着脱自在となるよう枢着させる。
【００３０】
カシメ片７４及び化粧リブ７６の間となる上記のパネル固着部には、その周囲の４辺を後方へ折曲させて、所定の色の塗料にて着色された塗装付き板金材にて形成された扉パネル９の補強片９１が係合される。補強片９１は、このパネル固着部のカシメ片７４を、図１０（ｂ），（ｃ）に示すように内側へ向けて折曲させて枠材７１、７２、７３，７３を固着させるが、この構成により扉パネル９が補強されることとなって、扉体６と箱本体２との開閉を安定に行うことができる。また、補強片９１を上記パネル固着部に係合させカシメを行ったときに周囲の破断面がほぼ覆われるため、塗装作業を行うことなく錆防止が達成され、扉体６製作時の作業性をより向上させることができる。
【００３１】
上記扉パネル９には、左側となる、上記被枢支部７５の反対側の枠材７１に近接させて、図２に示すように、扉閉止具１０の取り付けられる所定形状の取付孔９２が形成されている。扉閉止具１０は、扉パネル９の前後方向に出没自在となるよう配設されたハンドルをもったハンドル金具１０１が、扉パネル９の裏面側に配設される扉閉止片１０２を回動させるよう上記取付孔９２にねじ固定される。この扉閉止具１０は、枠材７１の化粧リブ７６裏面を扉止めリブ３６に当接させ位置決めされた扉体６を、その扉閉止片１０２を扉閉止リブ３ｃに当接させ、ガタツキを少なくして、閉止させることができて浮き沈みがなく、美観良く閉止状態とすることができる。
【００３２】
この扉体６も、上記の枠材７１、７２、７３，７３と扉パネル９とを組み合わせるときには、その４隅に枠材相互を固定させる被カシメ片８１をもった合成樹脂材料やアルミニウム材料製の隅部材８をそれぞれ設けて組み合わせ作業がなされて固定される。したがって、縦横の接合作業を容易に行うことができ、また、この隅部材８にて補強片９１同士も連結されて、扉体６自体の強度をより向上できる。
【００３３】
上記被枢支部７５の側となる上下の隅部材８の背面には、図１２（ａ）に示すように、略垂直位置とした扉体６の長手方向の移動を阻止させるスライド止め部材１１が設けられる。このスライド止め部材１１は、扉体６を略垂直位置の開位置にて、前記箱本体２の上下各側板３３，３３に設けられた扉止めリブ３６に当接させて位置決めさせる位置決め片１１１を有している。
【００３４】
スライド止め部材１１は、図１２（ａ）、（ｂ）に示すように、隅部材８の下方に設けられた係合孔８２に、コイルスプリング８３の一端を位置決めさせてコイルスプリング８３とともに係合させ、容易に脱落しないようばね付勢されて、位置決め片１１１が枠材７３側となる上又は下方向へ突出するよう装着される。そして、図１３に示すように、位置決め片１１１の基端の上下端面が、枢支部３５の両端面に当接してスライド止めとなり、また、位置決め片１１１を扉止めリブ３６に当接させて略垂直位置の開位置に位置決めさせる。
【００３５】
上記箱本体２内部に設けられる中蓋１２は、略平板状で、箱本体２内方に収納される漏電ブレーカあるいは分岐ブレーカ等の電気機器の前面側を露出させる所定形状の開口１２２、１２３及び、中蓋１２自体を箱本体２へ固着させる上支持部１２７の装着される開口１２４の穿設された蓋パネル１２１と、該上支持部１２７とでなる。この蓋パネル１２１は、その４方が後側に折曲されてその縁部１２５が、図１１に示す如く、上記中蓋支持片３７に支持されるようになっている。また、この中蓋１２は、箱本体２へ取付状態において下辺となる一辺の縁部１２５を切り欠いて、中蓋支持片３７の背面側に挿入させて中蓋１２を支持させる下支持部１２６が形成されている。
【００３６】
上支持部１２７は、ばね性を有する合成樹脂材料にて、上支持部１２７自体を上方へ付勢させるばね片１２８を一体に有して形成されている。そして、上記開口１２４に装着されて、上記下支持部１２６を中蓋支持片３７の背面側に挿入させて縁部１２５との間に係合させ、上支持部１２７の上部を中蓋支持片３７の背面側に挿入させて中蓋１２を支持及び固着させる。
【００３７】
次に、上記図示例の構成の電気機器収納箱１を製作する手順を、図７、図８に基づいて説明する。
【００３８】
箱本体２は、図７に示す如く、まず、隅部材４，４を矢印Ａに示す方向に差し込んで上下の側板３３，３３と隅部材４，４とを固定させる。次いで、その一方の側板３３に底板５の上下何れかの一端を矢印Ｂに示す方向に差し込んで固定して後、その側板３３に固定されている隅部材４，４に、左右の側板３１，３２をそれぞれ矢印Ｃに示す方向に差し込んで左右の側板３１，３２とその隅部材４，４とを固定させる。その後、上記の他方の側板３３に底板５の上下何れかの一端を矢印Ｄに示す方向に差し込んで左右の側板３１，３２、及びその側板３３を、その他方の側板３３に固定されている隅部材４，４を介して固定させる。
【００３９】
また、扉体６は、図８に示す如く、まず、隅部材８，８を矢印Ｅに示す方向に差し込んで上下の枠材７３，７３と隅部材８，８とを固定させる。次いで、その一方の枠材７３に扉パネル９の上下何れかの一端の補強片９１を矢印Ｆに示す方向に差し込みパネル固着部のカシメ片７４を内側へ向けて折曲させて固着させた後、その枠材７３に固定されている隅部材８，８に、左右の枠材７１，７２をそれぞれ矢印Ｆに示す方向に差し込んで左右の枠材７１，７２とその隅部材８，８とを固定させる。その後、上記の他方の枠材７３に扉パネル９の上下何れかの一端を矢印Ｇに示す方向に差し込んで左右の枠材７１，７２、及びその枠材７３を、その他方の枠材７３に固定されている隅部材８，８を介して固定させる。
【００４０】
こうして、上記の組立により、隅部材４、８を介して側板又は枠材の相互が固定されるので、縦横の接合作業を容易に行うことができ、また、隅部材４、８にて箱本体２及び扉体６自体の強度を向上できる。また、上記箱本体２内部には、側板３３、３３に連設されている内器支持溝３８にて、溶接、ねじ止め等により内器固定部材を支持するための取付部材や中蓋支持部材を設けることなく、箱本体内方に収納する電気機器を固定させ、また、中蓋支持片３７にその電気機器の前面側を露出させる中蓋１２の縁部１２５を支持させることもできので、溶接、ねじ止め等の作業追加による製造コストの上昇が回避される。
【００４１】
また、上記電気機器収納箱１を建物の躯体に設置するときには、まず上記扉体６、中蓋１２を取り外した状態で箱本体２を固定させ、次いで、箱本体２内方に電気機器を収容させた後、中蓋１２を取り付けて扉体６を箱本体２の開口面と略垂直位置として被枢支部７５を枢支片３ａに係合させて枢着片３ｂに支持させ枢着させる。すなわち、枢支部３５の枢着片３ｂにて、扉体６が略垂直位置まで開閉可能となるよう扉体６が枢着され、また、この扉体６の長手方向の移動が上記スライド止め部材１１にて止められ比較的容易に扉体６が箱本体２へ着脱される。さらに、上記中蓋１２は、それ自体をワンタッチにて支持及び固着させ着脱することができて、収納された電気機器のメンテナンスも容易に行うことができる。
【００４２】
ところで、上記構成の扉体６の枢支部分において枢支部３５が押出成型時に同時に形成され、また、扉体６が全長にわたってその枢支部３５にて枢支されて開閉されるので、使用に際して箱本体２内に塵埃等が侵入せず、また、その枢支部分が扉体６の長手方向の大きさに対応させて構成されて扉体６の重量変化に対応可能となるという優れた効果を奏し得る。
【００４３】
なお、本発明の電気機器収納箱は、上述したもののみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【００４４】
