Description

【０００１】
【発明の属する技術分野】
本発明は、床用配線器具を床下埋設部材に締結して床面に配設する床用配線器具の取付構造に関するものである。
【０００２】
【従来の技術】
従来より、床面に床下埋設部材を埋設し、この床下埋設部材に床用配線器具を締結して床面に配設する床用配線器具の取付構造がよく用いられている。
【０００３】
これは、図１３に示すように、床面に上方に開口した略箱状の床下埋設部材２’を埋設し、取付枠６’の取付用開口６１にコンセント等の床用配線器具１を締結部材５’にて取付け、床下埋設部材２’の縁鍔部２６の固着孔２６ａに取付枠６’を介して固着具２５を固着して取付けるものである。図中の１０，６２はそれぞれ締結部材５’，固着具２５が挿通される挿通孔を示す。
【０００４】
ところで、床面には、複数の仕上げ材が設けてあるため目地が形成される。そして、このような床面に、平面視において外殻が目地に平行か又は直交するように床下埋設部材２’が配設されなかった場合、図１３に示す従来例にあっては、矩形状をした床用配線器具１も床面の目地に平行か又は直交するようには配設されず、非常に見苦しく美観が損なわれてしまうものであった。
【０００５】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、床用配線器具の床下埋設部材に対する取付け向きを回動調整することができると共に、雄ねじ，雌ねじからなる締結用の部材にて床用配線器具を挟着した状態で床下埋設部材に強固に固定することができる床用配線器具の取付構造を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために本発明に係る床用配線器具の取付構造は、床用配線器具１を床下埋設部材２に締結して床面に配設する床用配線器具の取付構造であって、床下埋設部材２に床面と平行な長孔３を設け、雌ねじ孔４０を有する可動部材４の孔内移動部４１を前記長孔３内に長手方向に移動自在に配置して可動部材４を移動自在に配設し、前記可動部材４の雌ねじ孔４０に雄ねじが刻設された締結部材５を螺着することで床用配線器具１を床下埋設部材２に締結することを特徴とするものである。このような構成とすることで、床用配線器具１を既に床面に埋設してある床下埋設部材２に締結するに当たって、床用配線器具１の床下埋設部材２に対する向きを回動調整することで美観を損ねないように床面の目地等の模様や壁面や柱に対して所望の向きに配置することが可能となるものであり、また、雄ねじが刻設された締結部材５と雌ねじ孔４０が穿設された可動部材４とで床用配線器具１と床下埋設部材２とを挟着したような状態で強固に固定できるものである。
【０００７】
また、床下埋設部材２の長孔３を上下方向に開口するように形成し、可動部材４の孔内移動部４１の上下端部に前記長孔３の周縁部３１の上下にそれぞれ位置する上係止部４２と下係止部４３とを設けることが好ましい。このような構成とすることで、可動部材４が長孔３から抜け落ちることがないものである。
【０００８】
また、可動部材４の孔内移動部４１を上下を長手方向とする軸状に形成し、該孔内移動部４１内に雌ねじ孔４０を同軸状に穿設することが好ましい。このような構成とすることで、雌ねじ孔４０を設けるために可動部材４ａに新たな部分を付加する必要がないものである。
【０００９】
また、可動部材４がボルトＢ₁とナットＮとからなり、前記ボルトＢ₁の頭部を上係止部４２とすると共に軸部に孔内移動部４１を形成し、前記ボルトＢ₁の軸部に螺着される前記ナットＮを下係止部４３とすることが好ましい。このような構成とすることで、容易な構成で孔内移動部４１内に雌ねじ孔４０を同軸状に穿設することが可能となる。
【００１０】
また、可動部材４の孔内移動部４１と雌ねじ孔４０とを並列状に設けることが好ましい。このような構成とすることで、長孔３内に配置される孔内移動部４１と雌ねじ孔４０とを独立して別々に配置することができて、既製の床下埋設部材２と床用配線器具１とに対応することが可能となる。
【００１１】
また、可動部材４がボルトＢ₂とナットＮとからなり、前記ボルトＢ₂の軸部に孔内移動部４１を形成すると共に、前記ボルトＢ₂の頭部及び前記ナットＮのうちの一方及び他方をそれぞれ上係止部４２及び下係止部４３とし、ボルトＢ₂の頭部より孔内移動部４１と並列に筒部４４を連設し、該筒部４４内に雌ねじ孔４０を穿設することが好ましい。このような構成とすることで、容易な構成で孔内移動部４１と雌ねじ孔４０と並列状に設けることが可能となる。
【００１２】
また、ボルトＢ（Ｂ₁，Ｂ₂）の軸部にナットＮがボルトＢの頭部に近接するのを規制する規制部４５を設けることが好ましい。このような構成とすることで、ナットＮがボルトＢの頭部に近接するのを規制することが可能となる。
【００１３】
また、可動部材４の孔内移動部４１が長孔３の両側の長手方向端縁にそれぞれ複数箇所で近接して長孔３内での回転が防止される断面形状に形成されることが好ましい。このような構成とすることで、締結部材５を締結する際に孔内移動部４１が長孔３内で供回りするのが防止される。
【００１４】
また、可動部材４の雌ねじ孔４０の挿入口近傍に締結部材５を雌ねじ孔４０へ誘導する誘導部４０ａを設けることが好ましい。このような構成とすることで、暗い場所や見え難い場所でも締結部材５の雌ねじ孔４０への締結がスムーズに行える。
【００１５】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１６】
床下埋設部材２は、図１に示すように、略矩形状をした四方の側板部２１及び底板部とで主体が構成される上方に開口した略箱状のもので、内部にコンセント等の床用配線器具１が収納配設される。床下埋設部材２の側板部２１の上縁には、該上縁より内方に突出する平面視略ロ字状の略水平な板状をした周鍔部２２が取付けてある（図５参照）。この周鍔部２２は、隅部に穿設した挿通孔２２ａに固着具２５を挿通してこの固着具２５を側板部２１に設けた固着孔（図示せず）に固着して固定される。そして、この周鍔部２２に長孔３（後述する）が設けられる。
【００１７】
また、床下埋設部材２の側板部２１にはノックアウト部２１ａが複数形成してあり、床下埋設部材２の床面への埋設時に任意のノックアウト部２１ａを除去して床下配設の電線管８の端部を取付け、この電線管８内を挿通する電線８０を床用配線器具１に接続するものである。
【００１８】
本実施形態では、このような床下埋設部材２に後述する取付枠６を介して床用配線器具１を取付けるものであり、また本発明は、床用配線器具１を床下埋設部材２に回動調整自在に取付けるものである。すなわち、床下埋設部材２に設けた長孔３に可動部材４を移動自在に配設し、この可動部材４に締結部材５を螺着して取付枠６を締結することで床用配線器具１を床下埋設部材２に回動調整自在に配設するものであり、以下に説明する。
【００１９】
床下埋設部材２に設けられる長孔３は、側板部２１の上縁に取付けられる周鍔部２２に設けるもので、本実施形態では周鍔部２２の平面視で互いに対向する二辺の中央部の内側に形成してある（図５参照）。この長孔３は、その長手方向が平面視における床下埋設部材２の中心部（即ち周鍔部２２の中心部Ｃｅ）を中心とする円Ｃｉの長孔３が位置する部位の円周方向とほぼ一致するように形成するもので、本実施形態では特に、長孔３が前記円Ｃｉにほぼ沿うような円弧形状に形成してある。この長孔３は、上下方向に開口するものであり、また、長孔３の長手方向の長さはｌ，幅はｗ（ｌ＞ｗ）に形成してあり、長孔３の上下方向長さはｔ（即ち周鍔部２２の厚み）に形成してある。
【００２０】
次に、長孔３に配置される可動部材４について説明する。可動部材４は、長孔３内に位置する孔内移動部４１と、孔内移動部４１の上下端部にそれぞれ設けられて長孔３の周縁部３１の上下に位置する上係止部４２と下係止部４３とで主体が構成され、後述する締結部材５が螺着される雌ねじ孔４０が穿設されるものである。本実施形態においては、図２に示すように、可動部材４ａがボルトＢ₁とナットＮとで構成されるもので、以下に説明する。
【００２１】
ボルトＢ₁は、平面視円形状をした頭部と該頭部より突設される軸部とからなり、前記軸部に孔内移動部４１を形成すると共に、頭部を上係止部４２とするものである。ボルトＢ₁の頭部（即ち上係止部４２）は、平面視において径がｄ₂の円形状をした板状のもので、径ｄ₂は長孔３の幅ｗよりも大きく（ｄ₂＞ｗ）してある（図５参照）。そして、前記ボルトＢ₁の頭部からは下方に向けて軸部が突設されるのであるが、この軸部の頭部からの突出基部が長孔３内に配置される孔内移動部４１となり、孔内移動部４１より下側の部分はナットＮが螺着されるねじ部ｂとなる。
【００２２】
孔内移動部４１は、図２（ｅ）に示すように、平面視において一辺の長さｄ₁が長孔３の幅ｗと同程度かこれより若干小さい略正方形状に形成してあり、また上下方向長さＴ（図２（ｄ）参照）は、長孔３の上下方向長さｔより若干長く形成してある。このようにすることで、孔内移動部４１が長孔３内に配置された際に長手方向に移動自在とすることができると共に、この孔内移動部４１が平面視において長孔３内で回転（自転）するのが防止される。
【００２３】
また、孔内移動部４１の他例として、平面視における形状（即ち水平断面形状）が上述した略正方形状のもの以外に図２（ｆ）に示すように大略長方形状をしたものであってもよい。このものにあっては、水平断面の長手方向の長さを長孔３の長手方向長さｌより小さく、短手方向の長さｄ₁を長孔３の幅ｗと同程度かこれより若干小さく形成してあり、上述した水平断面が略正方形状のものと同様の効果が得られるものである。
【００２４】
このように、孔内移動部４１の水平断面形状において、長孔３の両側の長手方向端縁にそれぞれ複数箇所（図２（ｅ），図２（ｆ）に示すものでは長孔３の長手方向端縁に沿う直線部分全体）で近接することで、孔内移動部４１が長孔３内で回転（自転）するのが防止される。
【００２５】
そして、孔内移動部４１の下方の部分はねじ部ｂが形成される。ねじ部ｂは径がｄ₁の断面円形の軸の外面に雄ねじを刻設したもので、ナットＮが螺着される。
【００２６】
本実施形態では、このようにボルトＢ₁の軸部において、頭部からの突出基部に水平断面形状が略矩形状をした孔内移動部４１を形成し、その下側に断面円形のねじ部ｂを形成するものであるが、これに対して、特に図示はしないが、ボルトＢ₁の軸部全体にねじ部ｂを形成して該軸部の頭部からの突出基部近傍を孔内移動部４１とするものであってもよい。この場合、ナットＮを軸部に頭部からの距離がＴ（図２（ｄ）参照）の位置にまで螺着してナットＮと頭部との間の軸部を孔内移動部４１とすることになるが、この距離Ｔを尺等で計測するのでは作業が煩雑となるため、予め軸部にナットＮが頭部に近接するのを規制する規制部を設けておくことが好ましいものである。この点において本実施形態では、ボルトＢ₁の軸部の頭部からの突出基部に水平断面形状が略矩形状をして且つねじ部が形成されていない孔内移動部４１を形成してあるため、この孔内移動部４１の下端部が規制部４５（図２（ｂ）参照）となるものである。
【００２７】
また、このボルトＢ₁には、孔内移動部４１が形成される軸部及び頭部の内部に上下方向に貫通する雌ねじ孔４０が軸部と同軸状に穿設される。このように孔内移動部４１と雌ねじ孔４０とを同軸状に設けることで、雌ねじ孔４０を設けるために可動部材４ａに新たな部分を付加する必要がない。また、この雌ねじ孔４０には、後述する締結部材５が上方より螺着される。また更に、雌ねじ孔４０の締結部材５の挿入口（即ち上端部）には、締結部材５の雄ねじが雌ねじ孔４０の雌ねじに螺合するように誘導するための上方に開口する円錐側面状をした誘導部４０ａが形成してあり、暗い場所や見え難い場所でも締結部材５の雌ねじ孔４０への締結がスムーズに行える。
【００２８】
ボルトＢ₁のねじ部ｂに螺着されるナットＮは、本実施形態では図２（ｄ）に示すような六角ナットを用いているが、特にこれに限定されないものである。このナットＮは、図５に示すように、径の長い部分ｄ₃が長孔３の幅ｗよりも大きく（ｄ₃＞ｗ）してある。
【００２９】
このようなボルトＢ₁とナットＮとからなる可動部材４ａを長孔３に配設するには、図５に示すように、ボルトＢ₁の軸部を上方より長孔３に挿通して該軸部の孔内移動部４１を長孔３内に配置し、ねじ部ｂにナットＮを螺着することで行う。これにより、上係止部４２としてのボルトＢ₁の頭部が長孔３の上側に配置されると共に、下係止部４３としてのナットＮが長孔３の下側に配置され、ボルトＢ₁の孔内移動部４１が長孔３内に配置されることになり、上述したように長孔３内を移動する孔内移動部４１と共に可動部材４ａ全体も移動するものである。また、上係止部４２であるボルトＢ₁の頭部の径ｄ₂と、下係止部４３であるナットＮの径の長い部分ｄ₃は、それぞれ長孔３の幅ｗよりも大きく（ｄ₂＞ｗかつｄ₃＞ｗ）形成してあるので、可動部材４ａが長孔３から抜け落ちることがないものである。
【００３０】
次に、床下埋設部材２に締結される床用配線器具１及び取付枠６と、化粧プレート７について説明する。取付枠６は、図１に示すように平面視円形状をした枠で、床下埋設部材２に配設される際には上述した平面視略ロ字状の周鍔部２２の内部の開口を閉塞するものである。この取付枠６の内部には平面視略矩形状をした取付用開口６１が穿設してあって、この取付用開口６１に床用配線器具１が取付けられる。また、取付枠６には、上述した床下埋設部材２の可動部材４ａの雌ねじ孔４０に対応する部分に、締結部材５が挿通される締結用挿通孔６２が穿孔してあり、また更に、後述する化粧プレート７の係止突起７２が係止される被係止孔６３が穿孔してある。なお、このような床用配線器具１及び取付枠６は、本実施形態のように別部材として用いるのではなく一体に形成してあってもよいものであり、また更に、床下埋設部材２に取付枠６を介して床用配線器具１を取付けるのでなく床用配線器具１のみを直接取付けるものであってもよい。
【００３１】
化粧プレート７は、床用配線器具１を上方に露出可能とするための平面視略矩形状をした挿通開口７１が内部に形成される平面視略コ字状をしたもので、取付枠６に取付けるための係止突起７２が下方に向けて突設してある。また、化粧プレート７の上面には、挿通開口７１の周縁に沿って平面視略コ字状をした蓋取付用段部７０が凹設してあり、この蓋取付用段部７０に平面視矩形状をした蓋部７３が開閉自在に取付けられる。
【００３２】
次に、以上のような床用配線器具１の床面へ取付けについて説明する。
【００３３】
床面に設けた埋設用凹所（特に図示せず）に床下埋設部材２を埋設すると共に、床下埋設部材２に上述したように電線管８の端部を取付ける。床下埋設部材２には、長孔３に可動部材４ａを移動自在に配設した周鍔部２２を取付けておく。そして、取付枠６に取付けた床用配線器具１に電線８０を接続し（図１参照）、取付枠６の締結用挿通孔６２に上方より挿通した締結部材５を可動部材４ａの雌ねじ孔４０に仮止めする（図３，図４参照）。
【００３４】
ここで、床面について説明する。床面には平面視略矩形状（本実施形態では正方形）をした複数の仕上げ材Ｃが隙間なく整然と設けてあって、この隣接する仕上げ材Ｃとの突合せ部に複数本の平行か又は直交する目地Ｌが形成される（図７，図８参照）。そして、床面に設ける上記埋設用凹所は、床下埋設部材２が所定の方向を向いて埋設されるように精密に形成するのは困難なものであり、このような埋設用凹所に埋設された床下埋設部材２は、通常は各側板部２１が上記目地Ｌと平行か又は直交するようには配設されないものである。
【００３５】
そして、このように各側板部２１が上記目地Ｌと平行か又は直交するように配設されなかった床下埋設部材２に、床用配線器具１が取付いた取付枠６を回動調整することなく取付け、この取付枠６に化粧プレート７を取付けた場合、図７（ａ）に示すように蓋部７３の端縁７３ａと床面の目地Ｌとが平行か又は直交するように配置されず、非常に見苦しく美観が損なわれてしまうものである。
【００３６】
そこで、上述したように取付枠６の締結用挿通孔６２に上方より挿通した締結部材５を可動部材４ａの雌ねじ孔４０に仮止めした状態で、可動部材４ａを長孔３の長手方向に移動調整して取付枠６を回動調整し、所定の向きを向いた状態で締結部材５を本締めして、下係止部４３を床下埋設部材２の長孔３の周縁部３１を下側より引き上げて取付枠６を床下埋設部材２に固定することで、図７（ｂ）に示すように、蓋部７３の端縁７３ａと床面の目地Ｌとが平行か又は直交するように配置されて、見栄えが良く配置することができるものである。なお図６（ａ）及び（ｂ）に、床下埋設部材２に床用配線器具１が取付いた取付枠６，化粧プレート７を取付けた状態の側面図及び側断面図をそれぞれ示す。
【００３７】
以上のような構成によれば、床下埋設部材２に長孔３を設けてこの長孔３内に可動部材４ａの孔内移動部４１を移動自在に配置し、この可動部材４を移動調整した後で可動部材４ａの雌ねじ孔４０に締結部材５を螺着して締付けて、床用配線器具１を取付枠６を介して床下埋設部材２に締結するものであるため、床用配線器具１を既に床面に埋設してある床下埋設部材２に締結するに当たって、平面視における床用配線器具１及び取付枠６、化粧プレート７や蓋部７３の床下埋設部材２に対する向きを回動調整することで美観を損ねないように床面の模様や壁面に対して所望の向きに配置することが可能となるものである。また、雄ねじが刻設された締結部材５と雌ねじ孔４０が穿設された可動部材４ａとで床用配線器具１と床下埋設部材２とを挟着したような状態で強固に固定できるものである。
【００３８】
また、図９に床下埋設部材２の他例を示す。図１に示す上例のものにあっては、側板部２１の上縁に平面視略ロ字状をした周縁部２２を固着具２５にて取付けるのに対して、図９に示す本例のものにあっては、側板部２１の上縁に内方に略水平に突出する縁鍔部２３を一体的に設け、この縁鍔部２４に長孔３を設けてある。このようにすることで、部品点数及び施工工数が削減される。
【００３９】
次に、他の実施形態について図１０に基づいて説明する。このものは、図１に示す上実施形態と大部分において同じであるため、同じ部分については同じ番号を付記して説明を省略し、主に異なる部分について説明する。
【００４０】
図１０に示す本実施形態は、可動部材４及び、床下埋設部材２の長孔３が設けられる部分において図１に示す上実施形態と異なる。詳述すると、図１に示す上実施形態にあっては、孔内移動部４１と雌ねじ孔４０とを同軸状に設けた可動部材４ａを長孔３に配設するのに対して、本実施形態では、孔内移動部４１と雌ねじ孔４０とを並列状に設けた可動部材４ｂを長孔３に配設する点において異なるものであり、更に、床下埋設部材２の長孔３が設けられる部分においても異なる。
【００４１】
可動部材４ｂは、図１１に示すように、ボルトＢ₂とナットＮとからなるもので、上実施形態と同様に長孔３内に位置する孔内移動部４１と、孔内移動部４１の上下端部にそれぞれ設けられて長孔３の周縁部３１の上下に位置する上係止部４２と下係止部４３とで主体が構成される。
【００４２】
ボルトＢ₂は、平面視矩形状をした頭部と該頭部より突設される軸部とで主体が構成され、更に、頭部からは軸部と並列状に筒部４４が突設される。このものにあっては、ボルトＢ₂の頭部を下係止部４３とすると共に、ナットＮを上係止部４２とするものである。そして、前記筒部４４内に雌ねじ孔４０を穿設するものである。このように孔内移動部４１と雌ねじ孔４０とを並列状に設けることで、孔内移動部４１と雌ねじ孔４０とを独立して別々に配置することが可能となって、既製の床下埋設部材２の長孔３と、床用配線器具１が取付いた取付枠６の締結用挿通孔６２とにそれぞれ孔内移動部４１と雌ねじ孔４０とが対応した可動部材４とすることができ、また、可動部材４にかかる負荷を分散することも可能となる。
【００４３】
本実施形態のものにあっても上実施形態と同様に、床下埋設部材２に長孔３を設けてこの長孔３内に可動部材４ｂの孔内移動部４１を移動自在に配置し、この可動部材４ｂを移動調整した後で可動部材４ｂの雌ねじ孔４０に締結部材５を螺着して締付けて、床用配線器具１を取付枠６を介して床下埋設部材２に締結するものであるため、床用配線器具１を既に床面に埋設してある床下埋設部材２に締結するに当たって、平面視における床用配線器具１及び取付枠６、化粧プレート７や蓋部７３の床下埋設部材２に対する向きを回動調整することで美観を損ねないように床面の模様や壁面に対して所望の向きに配置することが可能となるものであり、また、雄ねじが刻設された締結部材５と雌ねじ孔４０が穿設された可動部材４ｂとで床用配線器具１と床下埋設部材２とを挟着したような状態で強固に固定できるものである。
【００４４】
