Description

【０００１】
【発明の属する技術分野】
本発明は、机、テーブル等の天板に設けられる配線用空間を閉塞する配線カバー装置に関する。
【０００２】
【従来の技術】
例えば机等の天板において、配線の横送り、もしくは床面への通線等をする場合、天板に通線孔を開口したり、上面が開放した溝状の配線ダクトを設けたりすることが行なわれている。この場合、天板から、通線孔や配線ダクトに物が落下したり、配線が上方から見えて、外観を損なう等の問題があるため、従来は、通線孔や配線ダクトに配線カバーを取付けるようにしている。
【０００３】
このような配線カバーの取付け構造として、配線カバーであるエッジ部材の後端部を、取付部材に取付け、配線カバーを蝶番状に開閉自在にしたもの（特許文献１参照）や、配線ダクトの底部よりカバー支持部材を立設して、配線カバーを支持するようにしたものが知られている（特許文献２参照）。

特開２０００−２８７７５８号公報(図１〜図７)
【０００５】
【発明が解決しようとする課題】
しかし、上記従来の構成においては、取付部材または配線カバーが天板または配線ダクト等に固着されているため、取付け構造が複雑化し、取り付け作業が煩雑になるとともに、高コスト要因となり、また配線が不要な場合にも取り外すことはできず、外部から見えて、美観を損なうことがある。
【０００６】
本発明は、従来の技術が有する上記のような問題点に鑑み、配線カバーを必要に応じて容易に着脱することができるとともに、構成が簡単で、部品が少なく、ひいては低コスト化が図れ、しかも配線作業を容易とし、かつ配線終了後の外観の向上をも図れるようにした、配線カバー装置を提供することを目的としている。
【０００７】
【課題を解決するための手段】
本発明によると、上記課題は、次のようにして解決される。
【０００８】
(１) 机等の天板の後方に配線用の部品取付板を、天板から離間させて設置し、これらの間に形成される配線空間内における部品取付板の前面に、カバー支持部材を左右方向任意の位置に着脱可能に取付け、このカバー支持部材に、配線空間を上方から覆う配線カバーを着脱可能に支持させる。
【０００９】
（２）上記(１)項において、部品取付板の前面に、左右方向に向く係止溝を形成するとともに、カバー支持部材に、これを横倒し姿勢にしたとき部品取付板の係止溝への挿脱および左右方向への移動が可能で、かつ挿入後に起立姿勢まで回転させたとき、係止溝内面に当接して係止しうるようにした係止片を一体に設ける。
【００１０】
（３）上記(２)項において、カバー支持部材に、横倒し姿勢から起立姿勢まで回転したとき係止溝の開口縁の上下少なくともいずれか一方に当接してそれ以上の回転を阻止する制止片を設ける。
【００１１】
（４）上記(２)または(３)項において、カバー支持部材は、部品取付板の前面に対向し中央位置に係止片を有する基板部と、この基板部の前面から突出し、配線カバーを前後いずれの向きとしても支持しうるようにしたカバー支持部とを有するものとする。
【００１２】
（５）上記(４)項において、カバー支持部の上面に係合溝を設け、この係合溝に、配線カバーの下面に設けた下向きの突片を係合させることにより、配線カバーをカバー支持部により支持するようにする。
【００１３】
（６）上記(５)項において、係合溝の内面に突起を設け、この突起に、配線カバーの突片の側面に設けた係合爪が弾性係合することにより、突片を所要の弾性保持力を持って係合溝から抜け止めする。
【００１４】
（７）上記(５)または(６)項において、突片を、配線カバーの下面における前後方向の中央より前後いずれかに偏倚した部位に設け、かつカバー支持部の上面に、配線カバーを正規の向きとしたときと、前後反転させたときとにそれぞれ係合する複数の係合溝を設ける。
【００１５】
（８）上記(１)〜(７)項のいずれかにおいて、配線カバーの少なくとも前後いずれかの縁部に、軟質材により構成された折曲可能な開閉部を設ける。
【００１６】
【発明の実施の形態】
図１〜図５は、本発明の一実施形態を備える机を示す。
【００１７】
この机(１)は、前後方向を向く左右１対の水平の支持杆(２)(２)の下部に、前部脚杆(３)と後部脚杆(４)とを連結し、左右の支持杆(２)(２)の前後方向の中間部同士を、左右方向を向く連結杆(５)をもって連結するとともに、両支持杆(２)(２)をもって天板(６)の両側部を支持し、かつ天板(６)の後端より後方に突出する両支持杆(２)(２)の後端部により、左右方向を向く部品取付板(７)の左右端部を、その前面が天板(６)の後端より後方に離間するようにして支持して構成されている。
【００１８】
図２に示すように、部品取付板(７)の前面には、その全長に亘って、左右方向を向き、かつ前面の開口の下縁に上向き突条(８)を有する上下２段の係止溝(９)(９)が形成されている。上向き突条(８)の係止溝(９)の後面側には、前方上向きの傾斜面が形成されている。
【００１９】
また、部品取付板(７)の後面には、左右方向を向き、かつ後面が開口するとともに、その開口部の上下の縁に、互いに対向する突条(10)(11)を有する上下２段の係止溝(12)(12)が設けられている。
【００２０】
前面の上下の係止溝(９)(９)には、配線ダクト(13)を装着し、かつ上部の係止溝(９)には、天板(６)と部品取付板(７)との間の配線空間(14)の上方を閉塞する、下記の配線カバー(20)を装着して、配線カバー装置が構成されている。
【００２１】
配線ダクト(13)は、上下方向を向く後面板(15)と、その下端より前方に延出する底板(16)と、その前方より起立する、後面板(15)より低寸の前面板(17)とを備え、後面板(15)の背面に設けた下向きフック片(19)が、部品取付板(７)の係止溝(９)にそれぞれ係止されている。
【００２２】
次に、配線ダクト(13)の上方に配設される配線カバー装置について説明する。
【００２３】
図３〜図５に示すように、部品取付板(７)と天板(６)との間に形成される配線空間(14)内において、部品取付板(７)の前面に、カバー支持部材(30)が左右方向任意位置に着脱可能に取付けられ、このカバー支持部材(30)に、配線空間(14)を上方から覆う配線カバー(20)が着脱可能に支持されている。
【００２４】
カバー支持部材(30)は、部品取付板(７)の前面に対向して配置され係止溝(９)に取付けられる縦板状の基板部(21)と、基板部(21)の前面から突出し、配線カバー(20)を前後いずれの向きとしても支持しうるようにしたカバー支持部とを有している。
【００２５】
基板部(21)は例えば長方形状に形成され、その長辺および短辺とも、係止溝(９)の前面の開口の上下幅、すなわち係止溝(９)の上縁部(９a)と上向き突条(８)の上端部(8a)との間の上下幅よりも長く形成されている。
【００２６】
これにより、基板部(21)を部品取付板(７)の係止溝(９)に沿って左右方向に移動させる場合に、横倒し姿勢（図４および図５の（イ）参照）、および起立姿勢（図４および図５の（ロ）参照）のいずれにおいても、部品取付板(７)の係止溝(９)に落ち込むことなく、部品取付板(７)の前面に対向する状態が安定的に維持されるようになっている。
【００２７】
基板部(21)の背面側のほぼ中央位置には、これを横倒し姿勢にしたときに、部品取付板の係止溝(９)への挿脱、および左右方向への移動が可能で、かつ挿入後に起立姿勢まで回転させたとき、係止溝(９)の内面に当接して係止する係止片(23)、が一体に設けられている。
【００２８】
係止片(23)は、円柱状の軸部(23a)と、この軸部(23a)の後端に設けられた鍔部(23b)とからなる。軸部(23a)の径は、係止溝(９)の上下開口幅より僅かに小さく、係止溝(９)内の開口部分に挿入することができ、かつ挿入状態において、係止溝(９)に沿って左右方向にスライド移動することができる。
【００２９】
鍔部(23b)は、例えば軸部(23a)の先端部を径方向に延長した長円板状に形成され、その延長端側には、係止溝(9)の上向き突条(８)の後面側に係止できる傾斜面(23c)が形成されている。この鍔部(23b)の短径側寸法は、軸部(23a)の径と同一であるが、長径側寸法は、係止溝(９)の前面側開口の上下幅より十分に大きく、かつ係止溝(９)の内方の上下幅より、微少量大きく設定されている。
【００３０】
したがって、鍔部(23b)の長径側を、図４の(イ)の如く横倒し状態で係止溝(９)に挿入した後、軸部(23a)を中心として９０°回転させ、図４の(ロ)の如く、直立姿勢に起立したときには、鍔部(23b)の長径側両端が、係止溝(９)内の上下面に圧接固定されると同時に、鍔部(23b)の傾斜面が、上向き突条(８)の内面に圧接固定され、係止片(23)の先端部が、部品取付板(７)と上下方向に圧接状態となる。
【００３１】
カバー支持部材(30)の基板部(21)には、横倒し姿勢から起立姿勢まで９０°回転したとき、係止溝(9)の開口の上下面にそれぞれ当接して、それ以上の回転を制止する１対の制止片(24)(25)が、係止片(23)を両側から挟む配置で、例えば互いに逆向きの方向に切り起こされた傾斜片として一体に設けられている。
【００３２】
カバー支持部(22)は、基板部(21)の前面より前方に突出する垂直板状の左右１対の支持板(22a)(22a)を備えており、各支持板(22a)の上端における配線空間(14)の中央から等距離の前後位置には１対の下方を向く係合溝(26)(26)が設けられている。
【００３３】
両支持板(22a)(22a)における前後の係合溝(26)(26)に挟まれた中間部の前後の縁には、左右方向を向く１対の連結板(22b)(22b)の両端が固着され、両支持板(22a)(22a)の中間部は連結板(22b)(22b)により互いに連結されている。
【００３４】
各支持板(22a)における前後いずれかの係合溝(26)に、配線カバー(20)の下面における前後方向の中央より前後いずれかに偏倚した部位に設け下向きの突片(27)を係合させることにより、配線カバー(20)を前後いずれの向きとしてもカバー支持部(22)により支持しうるようになっている。
すなわち、図３に示す配線カバー(20)の向きを正規の向きとすると、このときは、突片(27)を後部の係合溝(26)に係合させることにより、また、配線カバー(20)を正規の向きから前後反転させたときは、突片(27)を前部の係合溝(26)に係合させることにより、カバー支持部(22)に支持させることができる。
【００３５】
前後の連結板(22b)(22b)における外側面のほぼ中央には、側面視三角形の突起(28)が設けられ、この突起(28)に、配線カバー(20)の突片(27)の側面に設けた係合爪(29)が弾性係合することにより、突片(27)を所要の弾性保持力を持って係合溝(26)から抜け止めしうるようにしてある。そのため、突片(27)または配線カバー(20)全体を、弾性を有する合成樹脂材料により形成するのが好ましい。
なお、突起(28)は、各係合溝(26)の内面に設けてもよい。
【００３６】
配線カバー(20)は、図５に示すように、前後方向のほぼ１／２の範囲が、硬質材により、肉厚の大きい部分(20a)として構成され、残りの他の１／２の範囲が、軟質材により、肉厚の小さい弾性撓曲可能な開閉部(20ｂ)として構成されている。本実施形態では、肉厚の大きい部分(20a)のみが、カバー支持部(22)に下面を接して載置されている。
【００３７】
配線カバー(20)を取付けるには、図４および図５の(イ)に示すように、まずカバー支持部材(30)を水平な横倒し姿勢にして、係止片(23)を部品取付板(７)の係止溝(9)に挿入し、カバー支持部材(30)を左右方向任意の位置に移動した後、係止片(23)の軸部(23a)を中心として垂直な起立姿勢まで回転させて、図４および図５の（ロ）に示す状態とし、これにより、係止片(23)を部品取付板(７)の係止溝(９)に係止させる。
【００３８】
カバー支持部材(30)を起立姿勢まで回転させると、基板部(21)に設けた制止片(24)(25)が係止溝(９)の開口の上下面に当接して停止するので、垂直起立状態を超えて回転することはない。
【００３９】
カバー支持部材(30)の位置および使用個数は任意であり、配線コードの落し込みの邪魔にならない位置を選択したり、鉛直強度を高めたいという要請に応じて、カバー支持部材(30)の個数や位置は自由に変更される。
【００４０】
部品取付板(７)に所要数のカバー支持部材(30)を取付けた後、配線の状態等に応じて、配線カバー(20)の前後方向の向きを定め、配線カバー(20)をカバー支持部材(30)上に載置し、配線カバー(20)の前後方向中央部を押し下げる。これにより、押し下げられた配線カバー(20)の突片(26)は、前後いずれかの係合溝(26)に嵌合され、かつ突片(26)の係合爪(29)が突起(28)に弾性係合すると、配線カバー(20)は、適度の弾性保持力を持って上方へ抜け止めされて、安定的に保持される。
【００４１】
配線カバー(20)を取付けた後、配線カバー(20)の下方の配線空間(14)内に配置されている配線の処理等が必要となった場合には、肉厚の小さい折曲可能な開閉部(20ｂ)の端縁部分を捲り上げて開口させることにより、必要な処理を行なうことができる。
【００４２】
以上の操作により、特別の器具を使用する必要なく、配線カバー(20)の取付作業を容易・迅速に行なうことができる。取付後においては、係止片(23)が係止溝(９)の内面に当接して係止することにより固定状態が得られ、垂直荷重に耐えるカバー構成を容易に得ることができる。
【００４３】
配線カバー(20)を取外すには、前述した取付け時と逆の操作を行なえばよい。すなわち、配線カバー(20)を持上げて、突片(26)を係合溝(26)から上方に外し、次いでカバー支持部材(30)を、垂直な起立姿勢から水平な横倒し姿勢に回転させて、係止片(23)を部品取付板(７)の係止溝(９)から取外せばよい。
【００４４】
【発明の効果】
請求項１記載の発明によると、カバー支持部材および配線カバーが着脱自在であるため、これらを必要な場合にのみ取付けることができる。したがって、不要な構成部品の無駄を省き、低コスト化を図ることができる。
【００４５】
また、取付け後に配線カバーが不要となった場合には、カバー支持部材とともに取外すことができるので、支持部材が固定されたまま外部から見える等の体裁を損なうことがなく、美観の向上を図ることも可能となる。
【００４６】
しかも、カバー支持部材の取付け位置を任意かつ自由に変更できるため、配線の落し込みの際等にカバー支持部材が邪魔になるような場合には、これを避けた位置に、カバー支持部材を取付ける等の対処が容易であり、配線作業をスムーズに行なうことができる。
【００４７】
さらに、鉛直強度を高めたいような場合には、カバー支持部材の個数や位置を自由に変更して組立てることもできる。
【００４８】
請求項２記載の発明によると、カバー支持部材を取付ける際、カバー支持部材の係止片を部品取付板の係止溝に横倒し状態で挿入して左右の位置決めをし、その後に起立姿勢まで回転する一連の手作業によって行なえるので、余分な器具等が不要で、取付作業が容易・迅速に行なえる。
【００４９】
また、取付後の状態においては、係止片が係止溝内面に当接して係止することにより、固定状態を得て、垂直荷重に耐える構成を容易に得ることができる。カバー支持部材を取外す作業についても、取付け時と逆の操作により容易に行なうことができる。
【００５０】
請求項３記載の発明によると、カバー支持部材の取付け時において、カバー支持部材が起立姿勢を超えて回転することが制止片により確実に制止されるため、取付け時の姿勢判断等に余分な注意を必要とすることがなく、容易に確実な取付けが行なえ、装着後の状態を安定させることができる。
【００５１】
また、制止片によってもカバー支持部材に作用する上下方向の荷重が分担されるため、高荷重に耐える機能を一層増大することができる。
【００５２】
請求項４記載の発明によると、カバー支持部材のカバー支持部により、配線カバーを、前後方向の向きを自由に変えて支持することができる。
【００５３】
請求項５記載の発明によると、配線カバーの下面に設けた下向きの突片を、カバー支持部の上面に設けた係合溝に係合させるだけで、配線カバーをカバー支持部に簡単に安定して支持させることができる。
【００５４】
請求項６記載の発明によると、配線カバーの突片が、振動等により、カバー支持部の係合溝から妄りに脱落することがなくなり、配線カバーを常に安定して支持することができる。
【００５５】
請求項７記載の発明によると、配線カバーの前後方向の向きを変えた場合のいずれの状態においても、配線カバーの突片がカバー支持部の係合溝に係合できるので、いずれの向きにおいても、カバー支持部材への配線カバーの固定保持が確実に行なえる。
【００５６】
請求項８記載の発明によると、配線カバー取付け状態において、軟質材により構成された開閉部を開操作することにより、配線空間内を観察したり、配線の取出し等の各種作業が可能となる。
【００５７】
また、例えばクランプ式のオプション金具等が、天板側もしくは部品取付板のいずれか一方に設けられているような場合、配線カバーの軟質材の向きを変えて取付けることが可能となる。
