Description

【０００１】
【発明の属する技術分野】
本発明は、床面の収納用凹部に配設され、使用時に配線器具本体が床上に突出し、不使用時に配線器具本体が床下に収納可能な上下動型床用配線器具に関するものである。
【０００２】
【従来の技術】
従来より、使用時にコンセント等からなる配線器具本体４’が床上に突出するとともに、不使用時に配線器具本体４’を床下に収納可能な上下動型床用配線器具が用いられている（例えば特許文献１乃至６参照）。この従来の上下動型床用配線器具は、図１１に示すように、開口部１０’を有する取付プレート１’と、取付プレート１’の開口部１０’を開閉する蓋部２’と、蓋部２’とともに上下動する器具保持部３’とで主体が構成される。
【０００３】
取付プレート１’は、床面に凹設された収納用凹部の周縁の床上面に載置固定され、中央部に収納用凹部と床上とを連通する開口部１０’が形成してある。蓋部２’は、取付プレート１’の開口部１０’を閉塞可能な板状のもので、その一端部を取付プレート１’の一端側に軸支するとともに他端部を自由端２０’として回動自在としてあって、取付プレート１’の上側に蓋部２’が上下動自在となるようにして開口部１０’を開閉するものである。
【０００４】
蓋部２’の下面側には、器具保持部３’が固定される。器具保持部３’は、コンセント等の配線器具本体４’を保持可能なように枠状等に形成されるものであるが、形状としては様々なものがある。この器具保持部３’には、配線器具本体４’の差込面４０’が蓋部２’の自由端２０’付近から下側に該蓋部２’とほぼ直交する状態となるように固定される。
【０００５】
この従来の上下動型床用配線器具は、使用時には、蓋部２’を上動させることで蓋部２’の下面側に器具保持部３’を介して取り付けてある配線器具本体４’の差込面４０’を床上に突出させ、プラグ等の接続部を差し込んで配線器具本体４’を使用するものである。また、不使用時には、蓋部２’を下動させて取付プレート１’の開口部１０’を閉塞するとともに、配線器具本体４’を床下の収納用凹部に収納するものである。
【０００６】
このような従来の上下動型床用配線器具にあっては、配線器具本体４’は上述したように差込面４０’が蓋部２’とほぼ直交するように器具保持部３’を介して固定されるため、不使用時に蓋部２’を下動させて配線器具本体４’を床下の収納用凹部に収納した際、配線器具本体４’の差込面４０’の上下長さｈが長い場合には、差込面４０’の下端部（即ち、蓋部２’に取り付けられている端部と反対側の端部）が床下深くに位置することとなり、このように大きな差込面４０’を有する配線器具本体４’の場合には収納可能な収納用凹部を設けることができず、またスラブ高さの低い床スラブの場合にも収納用凹部を設けることが困難で、配線器具を配設することができないものであった。
【０００７】
そこで、蓋部２’と器具保持部３’とをそれぞれ取付プレート１’に回動自在に配設したものが考えられた（例えば特許文献７、特許文献８参照）。
【０００８】
このものは、蓋部２’と器具保持部３’とをそれぞれ取付プレート１’に回動自在に且つ上方にばね付勢した状態で配設してあり、使用時には蓋部２’と器具保持部３’とを上動して互いに対向するように斜め上方に起立した状態で上端部同士が係止して保持されるものである。
【０００９】
しかしながら、このような従来の上下動型床用配線器具は、蓋部２’と器具保持部３’は、ばね力にて上方に回動するものであるためばねが破損すると起立不可能となるものであった。また、使用状態における蓋部２’と器具保持部３’との係止は、器具保持部３’が上方に回動するのを規制するような係止であり、器具保持部３’が下方に回動するのを抑止するのはばね力であるため、プラグを器具保持部３’の差込面に差し込もうとすると器具保持部３’はばね力に抗して押し下げられてしまってプラグの差し込みがし難いものであり、また、プラグの差し込み方向への不測の力が加わると破損する惧れがあった。また更に、使用状態での器具保持部３’の支持は器具保持部３’の軸支部分のみで為されるため、プラグの差し込み方向への不測の力が加わったような場合には力がこの軸支部分に集中して特に破損し易いものであった。また、使用を終えて蓋部２’と器具保持部３’とを閉じようとする場合、蓋部２’と器具保持部３’とは連動していないため器具保持部３’を下動した後で蓋部２’を下動して閉じることとなり、操作が面倒であった。

【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、スラブ高さの低い床スラブであっても床下に配線器具本体を収納可能であるうえ、使用状態において配線器具本体を堅固に固定できて破損し難く操作が容易な上下動型床用配線器具を提供することを課題とするものである。
【００１２】
【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上下動型床用配線器具は、開口部１０を有し床面に配設される取付プレート１と、取付プレート１に上下動可能なよう配設されて開口部１０を開閉する蓋部２と、取付プレート１の開口部１０に配設されて蓋部２とともに上下動する器具保持部３と、器具保持部３に保持される配線器具本体４と、で主体が構成され、取付プレート１の一端側に蓋部２の一端部を軸支するとともに、蓋部２の他端部を自由端２０として取付プレート１の他端側から上側に上下動自在となるように配設し、蓋部２とは別体の器具保持部３の一端部を取付プレート１の前記蓋部２の自由端２０が配設される側に軸支するとともに、器具保持部３の他端部を取付プレート１の前記蓋部２の一端部が軸支される側に自由端３０として上下動自在となるように配設し、配線器具本体４の床下への収納時に蓋部２を下動して取付プレート１の開口部１０を閉塞した際にこれに連動して器具保持部３が下動して蓋部２の下側に収納されて該器具保持部３に取り付けられた配線器具本体４の差込面４０が上向きに略水平となるとともに、配線器具の使用時に蓋部２を上動した際にこれに連動して器具保持部３が上動するような連動手段５を設けた上下動型床用配線器具において、連動手段５として蓋部２と器具保持部３のうちの一方に被係合部を設けるとともに、他方に前記被係合部内に摺動自在に係合されて被係合部側の変位に応じて所定位置に位置決めされる係合部を設け、被係合部は、蓋部２の上下動に連動して器具保持部３を上下動させるように係合部を誘導する誘導部５１ａと、蓋部２が使用状態まで上動した際に器具保持部３の自重によって係合部が下降して蓋部２および器具保持部３を使用状態に保持するように形成した位置決め部５１ｂと、を設けてな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、床下への収納時に器具保持部３に取り付けられる配線器具本体４の差込面４０が上向きに略水平となって収納され、差込面４０の上下長さｈが長い場合でも差込面４０の下端部が床下深くに位置することがないため、床下深さを深くとることができないスラブ高さの低い床スラブであっても上下動型床用配線器具を配設することが可能となるうえに、蓋部２と器具保持部３とが連動するため操作が容易となるとともに、蓋部２と器具保持部３とが係合して連動しているため使用状態を堅固に保持するとともに破損し難いものとすることができる。また、被係合部は、蓋部２の上下動に連動して器具保持部３を上下動させるように係合部を誘導する誘導部５１ａと、蓋部２が使用状態まで上動した際に器具保持部３の自重によって係合部が下降して蓋部２および器具保持部３を使用状態に保持するように形成した位置決め部５１ｂと、を設けてなるので、器具保持部３の自重によって係合部が下降して位置決め部５１ｂにより位置決めされて、蓋部２と器具保持部３とを使用状態で保持することが可能となる。
【００１３】
また、被係合部は長孔５１からなるとともに、係合部は長孔５１内を摺動する突部５２からなることが好ましい。このような構成とすることで、簡単な構成で係合部と被係合部を形成することができる。
【００１５】
また、被係合部は、係合部を係止する係止部５３を設けることが好ましい。このような構成とすることで、使用状態が不用意に解除されるのを防止することができる。
【００１６】
また、係合部及び被係合部を、使用状態において器具保持部３の自由端３０が蓋部２の略中間部に保持されるように形成することが好ましい。このような構成とすることで、使用時にプラグ６が差し込まれる配線器具本体４の差込面４０の上方を蓋部２の上半部が覆う状態となってプラグ６や配線器具本体４が保護される。
【００１７】
【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。
【００１８】
本発明の上下動型床用配線器具は、図１に示すように、開口部１０を有する取付プレート１と、取付プレート１の開口部１０を開閉する蓋部２と、蓋部２とともに上下動する器具保持部３と、器具保持部３に取り付けられる配線器具本体４とで構成される。
【００１９】
取付プレート１は、図３に示すように、中央部に矩形状の開口部１０が形成される枠状のもので、本実施形態では、略正方形状をした板部材の中央部に矩形状の凹段部１１を凹設し、この凹段部１１の一端辺から小幅の部分を後述する情報用配線器具本体４ｂの取付部１２として残すとともに、凹段部１１の前記取付部１２以外の部分を開口して開口部１０を形成してある（図１参照）。この取付プレート１は、床面に凹設された収納用凹部の周縁の床上面に載置されて固定され、このとき開口部１０を介して収納用凹部と床上とが連通される。取付プレート１には、蓋部２と器具保持部３とが配設される。
【００２０】
蓋部２は、図１に示すように、取付プレート１の開口部１０を閉塞可能なように平面視において前記開口部１０とほぼ同じかそれより若干大きく形成される板状のもので、本実施形態では上述した凹段部１１（即ち開口部１０と情報用配線器具本体４ｂの取付部１２とを合わせた部分）と同じ形状に形成してあり、凹段部１１に嵌入した時に蓋部２の表面２ａ（即ち開口部１０を閉塞した時の上面）と取付プレート１の上面１ａとが面一となるように形成してある。蓋部２及び取付プレート１は、配線器具の不使用時には床面の一部となるため、床面として耐え得る強度を有するように形成されるもので、材質は金属、合成樹脂、木材等特に限定されない。
【００２１】
蓋部２には、対向する一対の端辺からそれぞれ側片２１が垂下してあり、この側片２１には後述する被係合部としての長孔５１が形成される。この蓋部２は、一端部が取付プレート１の一端側に軸支されるとともに、他端部が自由端２０として取付プレート１の他端側より上側に上下動自在となって（即ち軸支された部分を中心として回動自在となって）、蓋部２が上下動することで取付プレート１の開口部１０を開閉するものである。更に詳述すると、蓋部２は、取付プレート１の開口部１０の上記情報用配線器具本体４ｂの取付部１２が形成される端辺と隣接して直交する一端辺側に軸支される。蓋部２から垂下される側片２１は、開口部１０の情報用配線器具本体４ｂの取付部１２が形成される側の端辺とこれに対向する端辺とに対応する端辺からそれぞれ連設してあり、この両側片２１において軸支される側の側端部から軸支用片２３を側方に延設するとともに、この軸支用片２３に軸部２４を突設してある。一方、取付プレート１には、前記軸部２４に対応する部分（即ち蓋部２の一端部を軸支する側の端部）に軸受片１３を垂下するとともに、この軸受片１３に軸受孔１４を穿設してあり、蓋部２の軸部２４を取付プレート１の軸受孔１４に嵌入して回動自在に軸支してある。
【００２２】
このように蓋部２は、自由端２０を下動すると取付プレート１の凹段部１１に嵌まり込んで開口部１０を閉塞し、自由端２０を上動すると開口部１０が開口されるようになっている。蓋部２には、自由端２０に取付プレート１の開口部１０の縁部に係止可能な係止爪２２が設けてあり、一方、取付プレート１の前記係止爪２２に対応する部分には開口部１０内に向けて突没可能な係止片（図示せず）が操作部１７にて突没されるように形成してあり、蓋部２で開口部１０を閉塞した状態でロックすることができる。また、蓋部２は、図５の符号１８に示すばねにて上方に回動する向きに付勢してあり、操作部１７にて係止爪２２による係止を解除することで蓋部２及び器具保持部３が自動で開くようになっている。なお、このばね１８を設けずに手動で蓋部２を回動させてもよい。
【００２３】
配線器具本体４は、図１等に示すように、器具保持部３を介して取付プレート１に配設されるもので、コンセント等の電力用配線器具本体４ａと、モジュラジャック等の情報用配線器具本体４ｂとがあるが、以下において特に断わりがない場合には電力用配線器具本体４ａを指すものとする。電力用配線器具本体４ａは、栓刃が突出したプラグ６が差し込まれるコンセント４ａ１（図６参照）や、ソケットが差し込まれるコンセント４ａ２（図７参照）等特に限定されず、また、スイッチ４１が付加されていてもよい（図６参照）。情報用配線器具本体４ｂは、後述するが、情報用器具保持部７を介して取付プレート１の取付部１２に取り付けられる。電力用配線器具本体４ａは、以下に説明する器具保持部３を介して配設される。
【００２４】
器具保持部３は、図１に示すように、蓋部２とは別体に形成され、中央部にコンセント等の配線器具本体４（４ａ）を保持するもので、形状は板状のものやロ字形等をした枠状のもの等、特に限定されない。配線器具本体４（４ａ）は器具保持部３内に嵌まり込み、差込面４０が上向きに露出可能となる。そして器具保持部３は、一端部を取付プレート１の上記蓋部２の自由端２０が配設される側に軸支するとともに、他端部を取付プレート１の上記蓋部２が軸支される側に自由端２０として配設するものである。更に詳述すると、器具保持部３には、蓋部２の自由端２０が配設される側の端辺部の両側に軸部（特に図示せず）が突設してあり、一方、取付プレート１には、前記器具保持部３に突設した軸部に対応する部分に軸受片（特に図示せず）を垂下するとともに、この軸受片に軸受孔（特に図示せず）を穿設してあって、蓋部２と同様にして器具保持部３の軸部を取付プレート１の前記軸受孔に嵌入して回動自在に軸支したものである。
【００２５】
このように、蓋部２と器具保持部３は、取付プレート１の対向する端部にそれぞれ軸支されて上下動自在となっているが、蓋部２と器具保持部３の上下動は連動手段５によって連動するもので、以下に説明する。
【００２６】
連動手段５は、蓋部２と器具保持部３のうち、一方に被係合部を設けるとともに、他方に被係合部内に摺動自在に係合されて被係合部側の変位に応じて所定位置に位置決めされる係合部を設けて構成するもので、本実施形態では、図１に示すように、被係合部として長孔５１を形成するとともに、係合部として長孔５１内を摺動する突部５２を形成してある。
【００２７】
被係合部としての長孔５１は、図４，図５に示すように、蓋部２の側片２１にそれぞれ形成してあり、蓋部２の表面２ａとほぼ平行となる直線状の誘導部５１ａと、誘導部５１ａから連設される位置決め部５１ｂとからなる。誘導部５１ａは、側片２１の軸支側の端部近傍から自由端２０側に向けて形成されるもので、本実施形態では自由端２０側の端部は側片２１の略中間部に位置している。また、位置決め部５１ｂは、誘導部５１ａから下側（即ち、蓋部２の表面２ａから離れる側）に連設されるもので、本実施形態では誘導部５１ａの自由端２０側の端部から軸支側の斜め下方に向けて連設される。一方、係合部としての突部５２は、器具保持部３の自由端３０側の端辺の両側に突設してあり、この突部５２が蓋部２の長孔５１にそれぞれ挿入してある。
【００２８】
なお、本願のように長孔５１を側片２１を貫通して形成してあると、長孔５１への突部５２の係合状態が外側より視認できて好ましいのであるが、側片２１の内側を凹設して長溝としてあってもよいものである。またなお、このような係合部と被係合部は、一方が蓋部２に且つ他方が器具保持部３設けてあればよいものである。
【００２９】
連動手段５による動作について説明する。図２または図５（ｃ）に示すように、蓋部２が下動した状態では、器具保持部３の突部５２は長孔５１の誘導部５１ａの軸支されている側の端部近傍に位置することとなって、器具保持部３の突部５２が設けてある自由端３０は下動されて蓋部２の下側に収納され、器具保持部３に取り付けられた配線器具本体４（４ａ）の差込面４０が上向きに略水平となる（以下、この状態を収納状態とする）。
【００３０】
次に、上記収納状態から図５（ｂ）に示すように蓋部２を上動していくと、蓋部２の変位に伴って長孔５１も軸支部分を中心に自由端２０側の端部が上方に回動して変位していく。このとき、長孔５１内に挿入されている器具保持部３の突部５２は長孔５１によって押し上げられることとなって、長孔５１の変位に応じてその内部での突部５２の係合位置が位置決めされる。
【００３１】
そして、図５（ａ）に示すように蓋部２を所定の位置まで変位させたとき、器具保持部３の突部５２は長孔５１の誘導部５１ａの自由端２０側の端部にまで移動し、器具保持部３の自重によって位置決め部５１ｂへと下降する。蓋部２の回動は突部５２が位置決め部５１ｂの側壁に当接して規制され、この状態（即ち使用状態）にて蓋部２及び器具保持部３が保持される。この使用状態では、図５（ａ）に示すように器具保持部３に取り付けられた配線器具本体４（４ａ）の差込面４０が斜め上方を向くため、プラグ６を差し込み難い机の下等に設置された場合でも、差込面４０が見えて差し込み易く、床上にこぼれた水分等が配線器具に浸入し難いとともに、位置決め部５１ｂを誘導部５１ａから下側に向けて連設してあるため、プラグ６の差込面４０への差し込み方向が位置決め部５１ｂの連設方向と同じとなり、プラグ６を差込面４０に差し込む際に配線器具本体４に下向きの差し込み力が加わっても突部５２が位置決め部５１ｂの底部にて支持されて器具保持部３が下方に押し下げられてしまうことがなく、プラグ６の差し込みがし易いとともに、プラグ６の差し込み方向への不測の力が加わっても破損し難い。また、器具保持部３の支持が器具保持部３の軸支部分と係合部及び被係合部の係合部分とで行われるため、器具保持部３の軸支部分に力が集中せず分散させることができて、一層破損し難くすることができる。
【００３２】
また、誘導部５１ａの自由端２０側の端部を側片２１の両端部間の途中（特に本実施形態では略中間部）に位置させているため、差込面４０の上方を蓋部２の上半部が覆う状態となって、プラグ６や配線器具本体４が上方から踏み付けられるのを防止してプラグ６、配線器具本体４を保護することができる。
【００３３】
更に本実施形態では、図４に示すように、長孔５１の位置決め部５１ｂに係止部５３が設けてある。係止部５３は、長孔５１の誘導部５１ａから位置決め部５１ｂへと落下した突部５２が容易に誘導部５１ａへ戻されてしまうことがないように、位置決め部５１ｂの下端部から蓋部２の軸支側に切欠して形成してある。このようにすることで、使用状態において蓋部２と器具保持部３とがともに自重で下動しようとする際に突部５２が係止部５３に嵌まり込んで係止されて（図４（ａ）参照）、使用状態を確実に保持することができる。また、床上の歩行者が蓋部２を踏み付けたり蹴躓いたりして蓋部２の表面２ａに下方側への力が加わっても使用状態が不用意に解除されるのを防止することができるとともに、前記のように力が加わった場合でもプラグ６や配線器具本体４が破壊されるのを防止できて安全性を確保することができる。また、配線器具本体４にスイッチ４１が付加してあるものにあってはスイッチ４１が誤ってＯＮ、ＯＦＦされるのを防止できる。
【００３４】
使用状態から収納状態とするには、蓋部２と器具保持部３とを手で掴んで係止部５３に係止されている突部５２を位置決め部５１ｂを介して誘導部５１ａへと戻し、蓋部２を下動すると突部５２が誘導部５１ａにて誘導されて器具保持部３も連動して下動し、配線器具本体４が床面の収納用凹部に収納されることとなる。このとき、蓋部２と器具保持部３とは係合部及び被係合部にて係合された状態で連動しているため、蓋部２を下動するだけて器具保持部３が下動されて操作が容易である。
【００３５】
上述したように、蓋部２と器具保持部３とが連動手段５によって連動するため、配線器具本体４（４ａ）の収納時において、器具保持部３が蓋部２の下側に略水平に位置することとなって、器具保持部３に取り付けられる配線器具本体４（４ａ）がその差込面４０が上向きに略水平となって収納されるため、差込面４０の上下長さｈが長い場合でも従来例のように差込面４０の下端部が床下深くに位置することがなく、床下深さは配線器具本体４（４ａ）の差込面４０から裏面側の厚みに依存するのみとなり、スラブ高さの低い床スラブであっても従来より浅い収納用凹部を設けるだけで上下動型床用配線器具を配設することが可能となり、本発明においては特に、被係合部及び、該被係合部内に摺動自在に係合されて被係合部側の変位に応じて所定位置に位置決めされる係合部にて連動手段を構成してあるため、操作が容易となるとともに、使用状態を堅固に保持することができて且つ破損し難い。
【００３６】
このような上下動型床用配線器具は、配線器具本体４のうち特に電力用配線器具本体４ａの差込面４０の上下長さｈが長いため器具保持部３に取り付けて上下動自在とするもので、配線器具本体４のうち情報用配線器具本体４ｂにあっては、差込面４０が小さいため上下動させる必要がないうえに、電力用配線器具本体４ａのものと比べて情報用配線器具本体４ｂ自体や、裏面側に接続されるリード線等が破損し易いため、取付プレート１に固定して非可動とする方が望ましいものである。
【００３７】
情報用配線器具本体４ｂは、図２に示すように、取付プレート１の凹段部１１に形成した取付部１２に情報用器具保持部７を介して取り付けられる。情報用器具保持部７は、図１０に示すように、上方に開口する略コ字状をした本体７１と、本体７１の両方の上端部から外側に連設される取付鍔部７２とからなり、本体７１の底部には情報用配線器具本体４ｂが取り付けられる開口部７３が形成してある。この情報用器具保持部７は、取付鍔部７２に穿設してある固着孔を介してねじ等の固着具７５にて取付プレート１の凹段部１１に形成した取付部１２の下面側に取り付けられ、情報用配線器具本体４ｂの差込面を取付プレート１の開口部１０より露出させるものである。
【００３８】
情報用配線器具本体４ｂとしては、モジュラジャック接続部４ｂ₁（図８（ａ）参照）や、ＢＮＣケーブル等の接続部４ｂ₂など特に限定されず、様々なものが付け替え自在に取り付けてある。
【００３９】
このように、情報用配線器具本体４ｂを取付プレート１に固定することで、情報用配線器具本体４ｂを蓋部２と連動することによる情報用配線器具本体４ｂ自体やリード線等が破損するのを防止することができる。
【００４０】
なお、図９に示すように、情報用配線器具本体４ｂを設けないものであってもよい。この場合、取付プレート１に情報用配線器具本体４ｂの取付部１２を設ける必要がなく、上下動型配線器具の小型化が図られるものである。
【００４１】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、連動手段として蓋部と器具保持部のうちの一方に被係合部を設けるとともに、他方に前記被係合部内に摺動自在に係合されて被係合部側の変位に応じて所定位置に位置決めされる係合部を設け、被係合部は、蓋部の上下動に連動して器具保持部を上下動させるように係合部を誘導する誘導部と、蓋部が使用状態まで上動した際に器具保持部の自重によって係合部が下降して蓋部および器具保持部を使用状態に保持するように形成した位置決め部と、を設けたので、器具保持部に取り付けられる配線器具本体の差込面の上下長さが長い場合でもスラブ高さの低い床スラブに上下動型床用配線器具を配設することが可能となるうえに、蓋部と器具保持部とが連動するため操作が容易となるとともに、蓋部と器具保持部とが係合して連動しているため使用状態を堅固に保持するとともに破損し難いものとすることができ、被係合部は、蓋部の上下動に連動して器具保持部を上下動させるように係合部を誘導する誘導部と、蓋部が使用状態まで上動した際に器具保持部の自重によって係合部が下降して蓋部および器具保持部を使用状態に保持するように形成した位置決め部と、を設けてなるので、器具保持部の自重によって係合部が下降して位置決め部により位置決めされて、蓋部と器具保持部とを使用状態で保持することが可能となる。
【００４２】

BACKGROUND OF THE INVENTION
The present invention relates to a vertically movable floor wiring device that is disposed in a storage recess on a floor surface, so that the wiring device body protrudes above the floor when in use and can be stored below the floor when not in use.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been used a vertically movable floor wiring device capable of storing the wiring device body 4 'under the floor when not in use, while the wiring device body 4' made of an outlet or the like protrudes above the floor when used (for example, patents). References 1 to 6). As shown in FIG. 11, this conventional vertically movable floor wiring apparatus includes a mounting plate 1 ′ having an opening 10 ′, a lid 2 ′ for opening and closing the opening 10 ′ of the mounting plate 1 ′, and a lid. The main body is composed of an instrument holding part 3 ′ that moves up and down together with the part 2 ′.
[0003]
The mounting plate 1 ′ is placed and fixed on the floor upper surface of the periphery of the recess for storage provided in the floor, and an opening 10 ′ that connects the storage recess and the floor is formed at the center. The lid portion 2 ′ is a plate-like member that can close the opening 10 ′ of the mounting plate 1 ′, and supports one end of the mounting plate 1 ′ on one end side of the mounting plate 1 ′ and the other end as a free end 20 ′. The opening 10 'is opened and closed so that the lid 2' can move up and down on the upper side of the mounting plate 1 '.
[0004]
An instrument holding portion 3 'is fixed to the lower surface side of the lid portion 2'. The appliance holding portion 3 ′ is formed in a frame shape or the like so as to hold the wiring appliance main body 4 ′ such as an outlet, but there are various shapes. The appliance holding portion 3 ′ is fixed so that the insertion surface 40 ′ of the wiring appliance body 4 ′ is substantially perpendicular to the lid portion 2 ′ from the vicinity of the free end 20 ′ of the lid portion 2 ′ to the lower side. Is done.
[0005]
This conventional up-and-down type floor wiring device is, when in use, the wiring device main body 4 ′ attached to the lower surface side of the lid portion 2 ′ via the device holding portion 3 ′ by moving the lid portion 2 ′ upward. The wiring surface 4 ′ is used by projecting the insertion surface 40 ′ onto the floor and inserting a connecting portion such as a plug. When not in use, the lid 2 'is moved downward to close the opening 10' of the mounting plate 1 ', and the wiring device body 4' is stored in a storage recess under the floor.
[0006]
In such a conventional vertically movable floor wiring device, the wiring device body 4 ′ is interposed via the device holding portion 3 ′ so that the insertion surface 40 ′ is substantially orthogonal to the lid portion 2 ′ as described above. Therefore, when the wiring device body 4 ′ is stored in the storage recess under the floor when the lid 2 ′ is moved downward when not in use, the vertical length h of the insertion surface 40 ′ of the wiring device body 4 ′ is Is long, the lower end of the insertion surface 40 ′ (that is, the end opposite to the end attached to the lid 2 ′) is located deep under the floor. In the case of the wiring device body 4 ′ having the surface 40 ′, it is impossible to provide a storage recess that can be stored, and it is difficult to provide a storage recess even in the case of a floor slab having a low slab height. The instrument could not be installed.
[0007]
In view of this, there has been considered one in which the lid 2 'and the instrument holding portion 3' are rotatably arranged on the mounting plate 1 '(see, for example, Patent Document 7 and Patent Document 8).
[0008]
In this device, a lid 2 'and an instrument holding part 3' are arranged in a state of being pivoted upward and spring-loaded on the mounting plate 1 ', respectively. The upper end portions are locked and held in a state where the portion 3 'is moved upward and is raised obliquely upward so as to face each other.
[0009]
However, in such a conventional vertically movable floor wiring device, the lid portion 2 ′ and the device holding portion 3 ′ are rotated upward by a spring force, and therefore cannot stand when the spring breaks. It was a thing. Further, the locking between the lid 2 ′ and the instrument holding part 3 ′ in use is a locking that restricts the instrument holding part 3 ′ from rotating upward, and the instrument holding part 3 ′ is positioned downward. Since it is the spring force that prevents the rotation of the device, the device holding portion 3 ′ is pushed down against the spring force when the plug is inserted into the insertion surface of the device holding portion 3 ′. It was difficult to insert the plug, and there was a risk of damage if an unexpected force was applied in the plug insertion direction. Furthermore, since the instrument holding part 3 ′ is supported only by the shaft support part of the instrument holding part 3 ′ in use, the force is applied when an unexpected force is applied in the plug insertion direction. It was particularly easy to break due to concentration on this shaft support part. When the lid 2 'and the instrument holding part 3' are closed after use, the instrument holding part 3 'is moved down because the lid 2' and the instrument holding part 3 'are not linked. Later, the lid 2 'was moved down and closed, and the operation was troublesome.

More specifically, the instrument holding portion 3 is provided with shaft portions (not shown in particular) protruding on both sides of the end portion on the side where the free end 20 of the lid portion 2 is disposed. A bearing piece (not shown) is suspended from the plate 1 at a portion corresponding to the shaft projecting from the instrument holding portion 3, and a bearing hole (not shown) is formed in the bearing piece. In the same manner as the lid portion 2, the shaft portion of the instrument holding portion 3 is inserted into the bearing hole of the mounting plate 1 and pivotally supported.
[0025]
As described above, the lid portion 2 and the instrument holding portion 3 are pivotally supported by the opposing end portions of the mounting plate 1 so as to be movable up and down, but the vertical movement of the lid portion 2 and the instrument holding portion 3 is interlocked. This is interlocked by means 5 and will be described below.
[0026]
The interlocking means 5 is provided with an engaged portion in one of the lid portion 2 and the instrument holding portion 3 and is slidably engaged in the engaged portion on the other side to respond to the displacement on the engaged portion side. In this embodiment, as shown in FIG. 1, a long hole 51 is formed as an engaged portion, and a long hole 51 is formed as an engaging portion. A protrusion 52 that slides inside is formed.
[0027]
As shown in FIGS. 4 and 5, the long holes 51 as the engaged portions are respectively formed in the side pieces 21 of the lid portion 2, and are linear guides that are substantially parallel to the surface 2 a of the lid portion 2. It consists of the part 51a and the positioning part 51b provided in a row from the guidance | induction part 51a. The guide portion 51 a is formed from the vicinity of the end portion of the side piece 21 on the shaft support side toward the free end 20 side, and in this embodiment, the end portion on the free end 20 side is at a substantially intermediate portion of the side piece 21. positioned. Further, the positioning portion 51b is connected to the lower side (that is, the side away from the surface 2a of the lid portion 2) from the guide portion 51a, and in this embodiment, from the end portion on the free end 20 side of the guide portion 51a. It is continuously provided toward the diagonally lower side on the shaft support side. On the other hand, the protrusions 52 as the engaging parts are provided on both sides of the end of the instrument holding part 3 on the free end 30 side, and the protrusions 52 are respectively inserted into the long holes 51 of the lid part 2. is there.
[0028]
In addition, when the long hole 51 is formed so as to penetrate the side piece 21 as in the present application, it is preferable that the engagement state of the protrusion 52 to the long hole 51 is visible from the outside. The inner side may be recessed to form a long groove. In addition, such an engaging part and an engaged part should just be provided in the cover part 2 and the instrument holding part 3 in the other.
[0029]
The operation by the interlocking means 5 will be described. As shown in FIG. 2 or FIG. 5C, when the lid portion 2 is moved downward, the protrusion 52 of the instrument holding portion 3 is in the vicinity of the end portion of the elongated hole 51 on the side where the guide portion 51 a is pivotally supported. Thus, the free end 30 provided with the protrusion 52 of the device holding part 3 is moved downward and stored in the lower side of the lid part 2, and is attached to the device holding part 3. The insertion surface 40 of (4a) becomes substantially horizontal upward (hereinafter, this state is referred to as a storage state).
[0030]
Next, when the lid part 2 is moved upward as shown in FIG. 5B from the stored state, the elongated hole 51 also moves toward the free end 20 side with the shaft support part as the lid part 2 is displaced. The end is pivoted upward and displaced. At this time, the protrusion 52 of the instrument holding part 3 inserted into the long hole 51 is pushed up by the long hole 51, and the engagement of the protrusion 52 inside the long hole 51 according to the displacement of the long hole 51. The position is positioned.
[0031]
And when the cover part 2 is displaced to a predetermined position as shown in FIG. 5A, the protrusion 52 of the instrument holding part 3 reaches the end of the long hole 51 on the free end 20 side of the guide part 51a. It moves and descends to the positioning part 51b by the weight of the instrument holding part 3. The rotation of the lid portion 2 is regulated by the protrusion 52 coming into contact with the side wall of the positioning portion 51b, and the lid portion 2 and the instrument holding portion 3 are held in this state (that is, in use). In this use state, as shown in FIG. 5A, the insertion surface 40 of the wiring device body 4 (4a) attached to the device holding part 3 faces obliquely upward, so that the plug 6 is difficult to be inserted under the desk or the like. Even when installed, the insertion surface 40 can be seen and inserted easily, moisture spilled on the floor is difficult to enter the wiring apparatus, and the positioning portion 51b is continuously provided from the guiding portion 51a downward. For this reason, the insertion direction of the plug 6 into the insertion surface 40 is the same as the connecting direction of the positioning portion 51 b, and even when a downward insertion force is applied to the wiring device body 4 when the plug 6 is inserted into the insertion surface 40, The part 52 is supported by the bottom of the positioning part 51b and the instrument holding part 3 is not pushed downward, so that the plug 6 can be easily inserted and an unexpected force in the insertion direction of the plug 6 is applied. Also damaged Hard. Moreover, since the support of the instrument holding part 3 is performed by the shaft support part of the instrument holding part 3 and the engagement part of the engaging part and the engaged part, the force is not concentrated on the shaft support part of the instrument holding part 3. It can be dispersed and can be made more difficult to break.
[0032]
In addition, since the end portion on the free end 20 side of the guide portion 51a is located in the middle between both end portions of the side piece 21 (particularly in the intermediate portion in the present embodiment), the lid portion 2 is located above the insertion surface 40. As a result, the plug 6 and the wiring device body 4 can be prevented from being stepped on from above and the plug 6 and the wiring device body 4 can be protected.
[0033]
Furthermore, in this embodiment, as shown in FIG. 4, a locking portion 53 is provided in the positioning portion 51 b of the long hole 51. The locking portion 53 is configured so that the protrusion 52 that has dropped from the guide portion 51a of the elongated hole 51 to the positioning portion 51b is not easily returned to the guide portion 51a from the lower end portion of the positioning portion 51b. 2 is formed on the side of the shaft support. By doing in this way, when both the lid 2 and the instrument holding part 3 are about to move down under their own weight in use, the protrusion 52 is fitted into the locking part 53 and locked (FIG. 4). (Refer to (a)), the use state can be reliably maintained. Further, even if a pedestrian on the floor steps on or kicks the lid portion 2 and a downward force is applied to the surface 2a of the lid portion 2, it is possible to prevent the use state from being inadvertently released. In addition, even when a force is applied as described above, the plug 6 and the wiring device body 4 can be prevented from being destroyed, and safety can be ensured. Further, in the case where the switch 41 is added to the wiring device body 4, it is possible to prevent the switch 41 from being turned ON / OFF by mistake.
[0034]
In order to change from the use state to the storage state, the lid 52 and the instrument holding part 3 are grasped by hand, and the protrusion 52 locked to the locking part 53 is returned to the guiding part 51a via the positioning part 51b. When the lid part 2 is moved downward, the protrusion 52 is guided by the guiding part 51a, the appliance holding part 3 is also moved downward, and the wiring appliance body 4 is stored in the storage concave part on the floor surface. . At this time, since the lid portion 2 and the instrument holding portion 3 are interlocked with each other while being engaged by the engaging portion and the engaged portion, the instrument holding portion 3 can be lowered only by moving the lid portion 2 downward. Easy to operate.
[0035]
As described above, since the lid part 2 and the instrument holding part 3 are interlocked by the interlocking means 5, the instrument holding part 3 is placed substantially horizontally below the lid part 2 when the wiring instrument body 4 (4 a) is stored. Since the wiring device body 4 (4a) attached to the device holding part 3 is positioned and the insertion surface 40 is accommodated so that the insertion surface 40 is substantially horizontal upward, the vertical length h of the insertion surface 40 is Even if it is long, the lower end of the insertion surface 40 is not located deep under the floor as in the conventional example, and the depth under the floor only depends on the thickness from the insertion surface 40 to the back side of the wiring device body 4 (4a). Thus, even with a floor slab having a low slab height, it is possible to dispose a vertically movable floor wiring apparatus by simply providing a shallower recess for storage than in the prior art. And slidably engaged in the engaged portion to respond to the displacement on the engaged portion side. Because Te have configured interlocking means at the engaging portion to be positioned at a predetermined position, operation with is facilitated, and hardly broken can be firmly held to use.
[0036]
Such a vertically movable floor wiring device is attached to the device holding portion 3 so that it can move up and down because the insertion surface 40 of the power wiring device main body 4a of the wiring device main body 4 is particularly long. In the information wiring device main body 4b of the wiring device main body 4, it is not necessary to move up and down because the insertion surface 40 is small, and the information wiring is compared with that of the power wiring device main body 4a. Since the instrument main body 4b itself, the lead wire connected to the back side, and the like are easily damaged, it is preferable that the instrument main body 4b is fixed to the mounting plate 1 to be non-movable.
[0037]
  As shown in FIG. 2, the information wiring device main body 4 b is provided with an information device holding portion on the mounting portion 12 formed on the concave step portion 11 of the mounting plate 1.7It is attached via. Information device holder710 includes a substantially U-shaped main body 71 that opens upward, and a mounting collar 72 that is continuously connected to the outside from the upper ends of both of the main bodies 71. Is formed with an opening 73 to which the information wiring device main body 4b is attached. This information device holder7Is attached to the lower surface side of the mounting portion 12 formed on the concave step portion 11 of the mounting plate 1 with a fixing tool 75 such as a screw through a fixing hole drilled in the mounting collar portion 72, and the information wiring device The insertion surface of the main body 4 b is exposed from the opening 10 of the mounting plate 1.
[0038]
As information wiring apparatus main body 4b, modular jack connection part 4b₁(Refer to FIG. 8 (a)) or a connecting part 4b such as a BNC cable₂There is no particular limitation, and various things are attached to be freely replaceable.
[0039]
Thus, by fixing the information wiring device main body 4b to the mounting plate 1, the information wiring device main body 4b itself, the lead wire and the like are damaged by interlocking the information wiring device main body 4b with the lid portion 2. Can be prevented.
[0040]
In addition, as shown in FIG. 9, you may not provide the information wiring instrument main body 4b. In this case, there is no need to provide the mounting portion 12 of the information wiring device main body 4b on the mounting plate 1, and the vertical movement type wiring device can be miniaturized.
[0041]
