Abstract

<P>PROBLEM TO BE SOLVED: To prevent soiling and deformation by heat of an outlet main body and a plug. <P>SOLUTION: A plate main body 20 is attached to a front surface of an attaching frame 10 to which the outlet main body 1 for 200V is attached. A cover 30 is supported by a shaft to be freely opened and closed in the front surface of the plate main body 20. For example, when a power source plug for an electromagnetic cooker for power source voltage of 200V is connected to the outlet main body 1 and the cover 30 is closed, the front surface of the outlet main body 1 in which blade receiving holes 4a to 4c are exposed can be covered with the cover 30. Therefore, since liquids such as water or oil is not spilt on the outlet main body 1 or the power source plug and the heat emitted from the electromagnetic cooker is not easily transmitted to the outlet main body 1 or the power source plug, the soiling and deformation by heat of the outlet main body and the plug can be prevented. <P>COPYRIGHT: (C)2004,JPO&NCIPI

【０００４】
【発明が解決しようとする課題】
ところで、従来の２００Ｖ用のコンセント装置を台所や洗面所のような場所に設置する場合、水や調理用の油などの液体がコンセント本体あるいはコンセント本体に接続された差込プラグにかかって汚れたり、あるいは電磁調理器の発する熱がコンセント本体若しくは差込プラグに伝わって変形するといった問題があった。
【０００５】
本発明は上記問題に鑑みて為されたものであり、その目的は、コンセント本体や差込プラグの汚れ並びに熱による変形などを防止したコンセント装置を提供することにある。
【０００６】

【０００８】
請求項３の発明は、請求項１の発明において、コンセント本体は、一対の電圧極用刃受穴と接地極用刃受穴とがコンセント本体の短手方向に並設されてなり、取付枠は、長手方向を水平方向に略一致させるように造営面たる壁面に配置されるとともにコンセント本体が長手方向を水平方向に略一致させて取り付け可能な取付部を有することを特徴とする。
【０００９】
請求項４の発明は、請求項２又は３の発明において、壁面と略平行にスライドさせることでプレート本体に対してカバーを着脱自在としたことを特徴とする。
【００１０】
請求項５の発明は、請求項１〜４の何れかの発明において、１００Ｖ用のコンセント本体が２００Ｖ用のコンセント本体に並べて取り付けられる取付部が取付枠に設けられ、１００Ｖ用及び２００Ｖ用のコンセント本体に接続された差込プラグのコードと干渉せずにプレート本体前面を閉塞可能な奥行き寸法にカバーが形成されたことを特徴とする。
【００１１】
【発明の実施の形態】
（実施形態１）
図１は本実施形態のコンセント装置を示す一部簡略化した分解斜視図、図２は正面図及び側面図をそれぞれ示している。このコンセント装置は、２００Ｖ用の刃受を具備するコンセント本体１と、コンセント本体１が取り付けられる取付部を有し造営面（壁面）に設けられた埋込孔にコンセント本体１の一部を埋め込む形で配置する取付枠１０と、少なくともコンセント本体１の刃受を露出する露出窓を有し取付枠１０の前面に取り付けられるプレート本体２０と、コンセント本体１の前面に開閉自在に被着されるカバー３０と、プレート本体２０と壁面との間に介装される防水パッキン４０と、スイッチボックスと取付枠１０を絶縁する絶縁カバー５０とを備えている。
【００１２】
コンセント本体１は、合成樹脂成形品からなる外郭２のボス部３前面に３つの刃受穴４ａ，４ｂ，４ｃが設けられ、この刃受穴４ａ，４ｂ，４ｃを通して差し込まれる差込プラグの栓刃を受ける刃受が外郭２の内部に収納されている。外郭２は、埋込形の大角形連用配線器具（ＪＩＳＣ８３０３参照）の２個モジュールに形成され、前面が開口する箱状に形成されて外郭２の後部を構成する外郭ボディ２ａと、前面にボス部３が突出するとともに後面が開口する箱状に形成されて外郭２の前部を構成する外郭カバー２ｂとを金属製の止め金具５，５で結合して構成される。なお、止め金具５，５には後述するように取付枠１０の固着用爪部１３ａ，１３ｂが係止する固着用係止部５ａ，５ａが設けてある。
【００１３】
ボス部３前面の３つの刃受穴４ａ，４ｂ，４ｃのうちで、電圧極用の一方の刃受穴４ｂが矩形短冊状に形成され、電圧極用の他方の刃受穴４ａが略Ｌ字状に形成されるとともに、互いの長手方向が同一方向となるように並設され、さらに接地極用の刃受穴４ｃが略半円形に形成されている。ここで、一対の電圧極用の刃受穴４ａ，４ｂと接地極用の刃受穴４ｃとはコンセント本体１の短手方向（図１における上下方向）に並設されており、２００Ｖ用とするために定格２０Ａ，２５０Ｖの極配置となっている（ＪＩＳＣ８３０３参照）。
【００１４】
取付枠１０は金属製であって、図３に示すように中央部に矩形の器具取付窓１１が設けられ、長手方向（図３における上下方向）の両端にはボックス取付部１２，１２が一体に形成されている。取付枠１０には器具取付窓１１の周縁における上下両側に取付部たる固着用爪部１３ａ，１３ｂがそれぞれ一対ずつ突設されるとともに、上側の固着用爪部１３ａの近傍部位には略Ｃ字状のかしめ用穴１３ｃが貫設されている。このかしめ用穴１３ｃにマイナスドライバのような工具を挿入してかしめ用穴１３ｃを広げるように器具取付窓１１の周縁部位を塑性変形させると、止め金具５に設けた固着用係止部５ａに固着用爪部１３ａを挿入係止することができる。つまり、器具取付窓１１の上下両側の周縁に設けた固着用爪部１３ａ，１３ｂをコンセント本体１の止め金具５の固着用係止部５ａに挿入係止することによって、図４に示すようにコンセント本体１を取付枠１０に取り付けることができる。このとき、取付枠１０に取り付けられたコンセント本体１のボス部３が器具取付窓１１を通して前方に露出する。
【００１５】
ところで、ボックス取付部１２には、造営面（例えば、壁面）に埋め込んだスイッチボックスに螺合する固定用ねじとしてのボックスねじ（図示せず）が挿通される長穴状のねじ挿通孔１４が１個ずつ設けられ、ねじ挿通孔１４の長手方向の両端近傍には上下方向に延長された補強リブ１５が打ち出されている。各ボックス取付部１２にはそれぞれねじ挿通孔１４の外側（上側又は下側）にプレート取付ねじ部１６がそれぞれ形成されており、後述するように各プレート取付ねじ部１６に取付ねじ６０を螺合させて取付枠１０の前面にプレート本体２０が取り付けられる。
【００１６】
絶縁カバー５０は合成樹脂成形品からなり、コンセント本体１のボス部３を挿通する矩形の開口部５１が中央部に設けられ、長手方向（図１における上下方向）の両端部には取付枠１０のボックス取付部１２を前面から覆うように被さる固定片５２が折り曲げ自在に設けられている。また、固定片５２にはねじ挿通孔１４並びにプレート取付ねじ部１６と連通する孔５３，５４がそれぞれ設けられている。而して、取付枠１０をスイッチボックスに取り付ける場合、図４に示すように固定片５２を折り曲げて各ボックス取付部１２の前面に覆い被せ、固定片５２の孔５３及び取付枠１０のねじ挿通孔１４に挿通したボックスねじで取付枠１０をスイッチボックスに取り付ければ、スイッチボックスと取付枠１０との間が絶縁カバー５０によって絶縁される。
【００１７】
プレート本体２０は金属材料（例えば、アルミなど）により全体が略矩形の扁平な形状に形成されており、前面中央部には取付枠１０の器具取付窓１１に挿通されたコンセント本体１のボス部３が挿通されて刃受穴４ａ〜４ｃを前方へ露出する露出窓２１が設けられ、図５に示すようにプレート本体２０前面の周縁部には露出窓２１を囲むように周壁２２が立設されている。なお、周壁２２の下部には後述するように差込プラグのコードを引き出すための引出口２２ａが設けてある。また、プレート本体２０前面における周壁２２の上部及び引出口２２ａの近傍には取付ねじ６０を挿通するねじ挿通孔２３が設けられており、このねじ挿通孔２３に挿通した取付ねじ６０を取付枠１０の各ボックス取付部１２に設けられたプレート取付ねじ部１６に螺合することで取付枠１０の前面にプレート本体２０が取り付けられる。
【００１８】
防水パッキン４０は柔らかい材質の合成樹脂（例えば、軟質塩化ビニルなど）により矩形枠状に形成され、取付枠１０とプレート本体２０との間に介装されて壁面とプレート本体２０との隙間から水分等が侵入するのを防ぐものである。
【００１９】
カバー３０は金属材料（例えば、アルミなど）により背面が開口する略矩形の箱状に形成され、図２に示すように上端に設けられた軸挿通部３１とプレート本体２０の前面上端部に設けられた枢支部２４との組み合わせによって形成される軸孔に回動軸２５を挿通することにより蝶番状に開閉自在にプレート本体２０に枢支される。また、カバー３０の下端部には差込プラグのコードを引き出すための切り欠き溝３２が設けられるとともに、鍵（図示せず）により施錠、解錠自在な錠部３３が設けられている。すなわち、錠部３３を施錠した状態ではプレート本体２０に対してカバー３０を開くことができなくなり、コンセント本体１に接続された差込プラグが誤って、あるいは悪戯で引き抜かれるのを防ぐことができる。
【００２０】
而して、上述のように構成される本実施形態のコンセント装置を造営面（例えば、壁面）に施工する場合、壁面に設けた埋込孔にコンセント本体１の外郭２の後端部を埋め込む形で取付枠１０を埋込孔の前面に配置してボックスねじによりスイッチボックスに取り付け、さらに壁面との間に防水パッキン４０を介装し取付ねじ６０で取付枠１０の前面にプレート本体２０を取り付ければよい。そして、図６（ａ）に示すようにカバー３０を開いてコンセント本体１に差込プラグ７０を差し込み接続してカバー３０を閉じる。カバー３０を閉じた状態ではプレート本体２０の引出口２２ａ並びにカバー３０の切り欠き溝３２を通して差込プラグ７０のコード７２が引き出されるが、コンセント本体１並びに差込プラグ７０はカバー３０に覆い隠されて保護される（図６（ｂ）参照）。
【００２１】
例えば、図７に示すように電磁調理器（いわゆるＩＨコンロ）が載置される壁形キッチンユニットのコンロ台Ｘに本実施形態のコンセント装置を施工した場合、電源電圧２００Ｖの電磁調理器の差込プラグ（電源プラグ）をコンセント本体１に接続してカバー３０を閉じれば、刃受穴４ａ〜４ｃが露出するコンセント本体１の前面をカバー３０で覆い隠すことにより、コンセント本体１や電源プラグに水や油などの液体がかからず、電磁調理器から発せられる熱がコンセント本体１や電源プラグに伝わりにくくなるから、コンセント本体１や差込プラグ７０の汚れ並びに熱による変形などを防止することができる。また、コンセント本体１は埋込形であるから、電磁調理器の設置スペースへの出っ張りが抑えられるという利点もある。
【００２２】
ところで、本実施形態の取付枠１０の代わりに大角形連用配線器具の取付枠（ＪＩＳＣ８３７５参照）を用いるコンセント装置においては、図８（ａ）に示すようにコンセント本体１の向きが９０度傾いて一対の電圧極用の刃受穴４ａ，４ｂが鉛直方向に並ぶ配置となる。一方、一般に２００Ｖ用の差込プラグ７０では電圧極用の栓刃７１ａと接地極用の栓刃７１ｂの並び方向に沿ってコード７２が引き出されている。そのため、差込プラグ７０を上記配置のコンセント本体１に接続したときにコード７２を水平方向に引き出さなければならず、図８（ｂ）に示すようにプレート本体２０’にカバー３０’をきっちりと閉めることができなくなり、見栄えが悪くなってしまう。
【００２３】
しかしながら、本実施形態においては専用の取付枠１０にコンセント本体１をその長手方向が水平方向に略一致するように取り付けているから、上述のようにコンセント本体１に差込プラグ７０を接続したときにプレート本体２０及びカバー３０の鉛直下面からコード７２を引き出すことができ（図６参照）、図８に示すようにプレート本体２０’及びカバー３０’の側面からコード７２を引き出す場合に比べてコード７２の引き回しを簡単且つ見栄えよく行うことができる。
【００２４】
（実施形態２）
本実施形態は、図９に示すように壁面と略平行にスライドさせることでプレート本体２０に対してカバー３０を着脱自在とした点に特徴があり、これ以外の構成については実施形態１と共通であるから説明を省略する。
【００２５】
プレート本体２０の周壁２２には上部及び両側部に側方へ突出する鍔部２２ｂが設けてあり、図示は省略しているがカバー３０内側の上部及び両側部には各鍔部２２ｂと係合する係合片が設けてある。
【００２６】
而して、プレート本体２０の上方から壁面と略平行にカバー３０を下方へスライドさせれば、カバー３０の上記係合片がプレート本体２０の鍔部２２ｂに係合してプレート本体２０の前面にカバー３０が取り付けられる。そして、カバー３０を取り付けた状態では、プレート本体２０及びカバー３０の鉛直下面からコード７２を引き出すことができる。
【００２７】
本実施形態はこのように構成したものであり、壁面と略平行にスライドさせることでプレート本体２０に対してカバー３０を着脱自在としたため、実施形態１におけるカバー３０の開閉構造に比較してカバー３０の開閉に必要なスペースを少なくすることができ、しかも、プレート本体２０とカバー３０を分離したことで実施形態１に比較してプレート本体２０及びカバー３０の清掃が簡単に行えるという利点がある。
【００２８】
（実施形態３）
本実施形態のコンセント装置は、既存の大角形連用配線器具の取付枠（図示せず）を横長に配置する構造とした点に特徴がある。なお、本実施形態における取付枠については従来周知であるから図示並びに説明を省略する。
【００２９】
図１０に示すように取付枠以外のプレート本体２０、カバー３０、防水パッキン４０、絶縁カバー５０の構造は基本的に実施形態１のものと共通である。すなわち、取付枠の横長配置に合わせてカバー３０の形状を横長とし、プレート本体２０の枢支部２４の位置を変更している。
【００３０】
而して、本実施形態のコンセント装置では既存の取付枠をその長手方向が水平方向に略一致するように壁面に配置することにより、コンセント本体１を実施形態１と同じ向きに埋込配設することができ、実施形態１のように専用の取付枠１０を使わずに差込プラグ７０のコード７２を鉛直下方へ引き出してカバー３０をプレート本体２０にきっちりと閉めることができる。しかも、壁面に配設したときの高さが低くなるから、実施形態１に比較してカバー３０の開閉に必要なスペースが少なくて済み、電気機器（例えば、電磁調理器）と壁面との隙間を狭くすることができる。
【００３１】
ところで、既存の取付枠を使用する場合、図１１に示すように２個モジュールのコンセント本体１とともに１個モジュールの１００Ｖ用のコンセント本体１’を取付枠に取り付けることができる。また、１００Ｖ用の差込プラグ８０が栓刃８１の突出する前面に背向した背面からコード８２が引き出されるものである場合、カバー３０の奥行きＤを１００Ｖ用のコンセント本体１’に接続された差込プラグ８０のコード８２と干渉しない寸法に設定すれば、プレート本体２０に対してカバー３０をきっちりと閉めることができ、１００Ｖ用及び２００Ｖ用の何れの電気機器にも対応可能となる。
【００３２】
