Description

【０００１】
【発明の属する技術分野】
本発明は、机、テーブル、作業台等の天板に設けられたコード挿通用の開口を閉塞するための装置に関する。
【０００２】
【従来の技術】
この種の従来のものとしては、例えば、実公昭６０−２２８１９号公報や特願平１０−８５５２７号の出願明細書等に記載されたものがある。
【０００３】
実公昭６０−２２８１９号公報に記載されている机は、天板の後部に左右方向を向く開口を形成し、この開口に、開口と補形をなす後方天板を、その後端部を中心に開閉自在として枢着するとともに、開口の左右両側面の上端部の前寄りの箇所に受体を突設し、後方天板を閉じた際には、後方天板の下面前端部を受体により支持して、後方天板が天板と同一平面となるようにしたものである。
【０００４】
後方天板の前縁部には、可撓性のある軟質の縁材が固着されており、後方天板により開口を閉塞した際には、天板上に載せられた電機機器等の配線コード、または後方天板の下方に配設された配線コードを、縁材と天板の後縁部との間に挿入して、後方天板の下方または上方に引き出せるようにしている。
【０００５】
特願平１０−８５５２７号の出願明細書等に記載されたものは、机の後方に、内部に配線ダクトが形成された框体状の配線ダクトユニットを併設し、配線ダクトユニットの上面開口の周縁部に前後１対のダクトカバーを載置することにより、上面開口を閉塞するものである。
前側のダクトカバーの後縁部と後側のダクトカバーの前縁部とには、それぞれ軟質の縁材が固着されており、両ダクトカバーを上面開口に被せると、両ダクトカバーの縁材同士が密接するようになり、天板やダクトカバー上に載せられた電機機器等の配線コード、配線ダクトに収納された配線コードを、両縁材の間からダクトカバーの上方または下方に引き出せるようになっている。
【０００６】
【発明が解決しようとする課題】
しかし、実公昭６０−２２８１９号公報の後方天板は、その後端部の枢着点と前端部の４点のみで机に支持され、また、特願平１０−８５５２７号のダクトカバーは、その周縁部が配線ダクトユニットの周縁部の上面開口の周縁部に支持されるので、後方天板とダクトカバーの中央部に電機機器等が載せられる等して、大きな荷重がかかった場合には、後方天板やダクトカバーが撓む等の変形を起こすおそれがある。
【０００７】
また、実公昭６０−２２８１９号公報の後方天板は、その後端部を机に枢着するようになっているため、後方天板の後縁部に軟質の縁材を取り付けることはできず、一方、特願平１０−８５５２７号の前側のダクトカバーは、その前縁部が、また、後側のダクトカバーは、その後縁部が、それぞれ配線ダクトユニットの上面開口の周縁部に載置されるので、前側のダクトカバーの前縁部及び後側のダクトカバーの後縁部に、軟質の縁材を取り付けることはできない。
【０００８】
よって、上記の後方天板とダクトカバーにおいては、いずれも、前後いずれか一方にしか、配線コードを通すための縁材を取り付けることができず、そのため、後方天板の下方空間または配線ダクトから、机または配線ダクトユニットの上方へ配線コードを引き出して天板等に載置された電機機器等に接続する場合に、縁材と天板の後縁部との間、または縁材同士の間における配線コードの引出位置が限定されてしまい、特定の箇所に配線コードが集中してしまうことがある。そのため、例えば、電源コード等の強電コードと、パソコンとそのマウスをつなぐケーブルのような弱電コードとが、縁材と天板の後縁部との間、または縁材同士の間で混線し、弱電コードが強電コードからノイズの影響を受けることがある。また、後方天板の下方空間や配線ダクト内においても、弱電コードと強電コードとが混線し易くなる。
【０００９】
さらに、天板上に載置した電機機器等から延出する配線コードを、整然とした状態で、縁材と天板の間または縁材同士の間に通すことができないので、見栄えが悪くなる。
【００１０】
また、実公昭６０−２２８１９号公報の後方天板は、机への着脱が面倒であり、特願平１０−８５５２７号のダクトカバーは、配線ダクトユニットの上面に単に載置されているだけであるので、外力がかかると、位置がずれたり、外れたりするおそれがある。
【００１１】
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、天板の開口を塞ぐダクトカバーの上面に電気機器等を載せた場合においても、ダクトカバーが撓んで変形したりすることがなく、かつ、電機機器等の配線コードを、机の下方に形成された配線ダクトから机の上方へ（またはその逆方向に）、整然とした状態で引き出すことができ、各配線コードの混線等を防止しうるとともに、ダクトカバーを開口に、簡単かつ確実に着脱しうるようにした、机等における配線用開口の閉塞装置を提供することを目的としている。
【００１２】
【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。
(１) 天板の上面に設けた配線コード挿通用の開口の下方に、前記配線コードを受支する配線ダクトを設けた机等において、前記配線ダクトの底部に、上方に向かって延出するカバー支持部を設け、該カバー支持部の上端部に、前記開口の少なくとも一部を閉塞するダクトカバーを支持するようにし、さらに、前記配線ダクトを、開口の長手方向に離間するようにして、天板の下面に取り付けられた複数のダクト保持部材と、１対のダクト保持部材により支持されたダクト部材とからなるものとし、前記カバー支持部をダクト保持部材に設ける。
【００１３】
(２) 上記(１)項において、ダクトカバーが、カバー支持部により支持される硬質材料製のカバー本体と、該カバー本体の少なくとも一側縁に設けられ、該側縁に対向する開口の縁部に向かって延出する軟質材料製の縁材とを備えるものとする。

【００２０】
左右１対の支持脚(２)の上部の後端角部には、凹入部(３)が形成され(図１及び図６参照)、この凹入部(３)には、それとほぼ補形をなすとともに、前上部に下向きのスリット(４)を設けた側部カバー(５)が嵌合されている。
【００２１】

【００２４】
(11)は、合成樹脂材により一体成形されたダクト保持部材であり、このダクト保持部材(11)の前後方向の中央部よりやや前側寄りの上面には、左右方向を向く凹溝(12)が形成され、凹溝(12)の後方はダクトカバー支持部(13)となっており、凹溝(12)の前方は天板連結部(14)となっている。
【００２５】
ダクトカバー支持部(13)の上面は、後述するダクトカバー(43)の底面が当接する水平な支持面(15)となっており、ダクトカバー支持部(13)の前後には、弾性撓曲可能な１対の上方を向く挾持片(16)(16)が立設され、両挾持片(16)の上端部には、互いに向かい合う側面視くの字(逆くの字)形の把持部(17)が形成されている。
【００２６】
ダクトカバー支持部(13)の後面には、左右１対の後向きの水平片(18)が突設され、水平片(18)の上面の内側部には、四角柱状の当接部材(19)が立設され、当接部材(19)の後面の下半部には、左右１対の挿入片(20)が後向きに突設されている(図５、図６参照)。
【００２７】
水平片(18)の外側部の下面には、やや肉厚で、その下端部が前向きに若干屈曲された下向き係止片(21)が突設されており、下向き係止片(21)の下端部の前面は、幕板(７)の係止孔(10)に挿入された際に、前面板(7a)における係止孔(10)の下縁より下方の後面に係合する当接面(22)となっている。
【００２８】
水平片(18)の外側部の上面には、薄肉で、かつ上端部が前向ほぼ水平に折り曲げられた抜け止め片(23)が形成されている。抜け止め片(23)の前端部はさらに薄肉となっており、この薄肉部の直後には、幕板(７)の係止孔(10)に挿入した際に、前面板(7a)における係止孔(10)の上縁部後面に弾性係合する係止爪(24)が形成されている。
【００２９】
天板連結部(14)の上面は、天板(６)の後端部下面に当接する当接面(25)となっており、当接面(25)のほぼ中央部には、天板(６)の底面板(6a)における係止孔(９)の両側縁部上面に弾性係合する左右１対の爪(26)を両側面に有する係合部材(27)が、上向きに突設されている。
【００３０】
ダクト保持部材(11)の前面には、下向係止片(28)が突設され、下向係止片(28)の左右両側下方には、左右１対の方形の係止孔(29)(29)が穿設され、ダクト保持部材(11)の後面には、１個の方形の係止孔(30)が穿設されている(図５、図６参照)。なお、ダクト保持部材(11)の後面にも、下向係止片(28)と同様のものを設けてもよい。
また、図６に示すように、ダクト保持部材(11)の下面ほぼ中央部には、前後面に爪(31)を備える係合部材(32)が下向きに突設されている。
【００３１】
ダクト保持部材(11)は、係合部材(27)を天板(６)の係止孔(９)に挿入して、左右の爪(26)を係止孔(９)の左右両側縁部に係止させ、また、下向き係止片(21)を幕板(７)の係止孔(10)に係止させるとともに、当接面(22)を前面板(7a)の後面に当接させ、同時に、抜け止め片(23)と挿入片(20)とを係止孔(10)に挿入して、抜け止め片(23)の係止爪(24)を、係止孔(10)の上縁部に弾性係合させ、かつ、当接部材(19)の後面を幕板(７)の前面に当接させることにより(図６参照)、天板(６)と幕板(７)との間に、前後、左右及び上下にがたつくことなく、確実に固定されている。
【００３２】
すなわち、下向き係止片(21)と抜け止め片(23)の側面、および内側の挿入片(20)の側面が係止孔(10)の左右両側縁に当接するので、ダクト保持部材(11)が幕板(７)に対して左右方向にがたつくことはない。
【００３３】
左右方向の長さを開口(８)の左右方向の長さの半分より短くした樋状のダクト部材(33)は、横長方形の配線挿通孔(34)を穿設した底板(35)の前後両縁部に、ほぼ垂直な前壁(36)と後壁(37)とを連設し、かつ前壁(36)と後壁(37)の上縁部に外向きの上片(38)を連設したものよりなっている。
【００３４】
底板(35)における配線挿通孔(34)の左右両側部には、平面視正方形の係止孔(39)が穿設され、前壁(36)の左右両端部には、左右２個ずつの斜め後下方を向く係合爪(40)が、また後壁(37)の左右両側部には、１個ずつの斜め前下方を向く係合爪(40)がそれぞれ切り出し成形され、前壁(36)と上片(38)との間の角部の左右両端部には、ダクト保持部材(11)の下向係止片(28)が係合しうる係合孔(41)が穿設されている。
【００３５】
ダクト部材(33)は、ダクト保持部材(11)の前後の係止孔(29)(30)に係合爪(40)(40)を係合し、係合部材(32)を係止孔(39)に挿入して、爪(31)を係止孔(39)の下縁に弾性係合させるとともに、下向係止片(28)を係合孔(41)に係合することにより、隣り合う左右のダクト保持部材(11)間に、ダクト保持部材(11)の下面及び前後両面に密接するようにして固定されている。
【００３６】
図２に示すように、４個のダクト保持部材(11)を開口(８)の直下に左右方向に並べて取り付け、隣り合う左右２個ずつのダクト保持部材(11)間に２個のダクト部材(33)を取り付けることにより、左右のダクト部材(33)間に、隙間(42)(図２参照)が形成されるようにしている。
【００３７】
開口(８)は、その長さのほぼ半分の長さの２個のダクトカバー(43)によって閉塞される。
ダクトカバー(43)は、比較的硬質の合成樹脂材から成形され、下部前後面に、ダクト保持部材(11)の把持部(17)が弾性係合しうる係合溝(44)が形成されたカバー本体(45)の上部前後面に、前後方向に延出する可撓性のある軟質の合成樹脂材からなる縁材(46)を取り付けたものである。
【００３８】
ダクトカバー(43)は、図１及び図６に示すように、カバー本体(45)の左右両端の下端部を前後の把持部(17)の間に押し込み、両把持部(17)を係合溝(44)に弾性係合させることにより、開口(８)の右(左)半分を閉塞するようにして取り付けられ、２枚のダクトカバー(43)により、開口(８)がほぼ完全に閉塞される(図１参照)。
なお、図６に示すように、ダクトカバー(43)を開口(８)に取り付けたとき、縁材(46)と天板(６)及び幕板(７)との間に若干の隙間が形成されるようにしているが、隙間を形成しない場合もある。
【００３９】
以上説明した本実施形態によれば、ダクトカバー(43)の下面が、複数のダクト保持部材(11)によって支持されているので、ダクトカバー(43)の上面に電気機器（図示略）等が載置された場合においても、ダクトカバー(43)が撓んだりすることはない。
【００４０】
また、ダクトカバー(43)を、その下面においてダクト保持部材(11)により支持するようにしたので、カバー本体(45)の前後両縁部に可撓性のある縁材(46)を取り付けることができ、それによって、図７に示すように、ダクト部材(33)の底板(35)の前部に通常のケーブル等の弱電コード(Ａ)を、また、底板(35)の後部に電源コードのような強電コード(Ｂ)を整然と区分して収納し、弱電コード(Ａ)を前方の縁材(46)側から引き出し、強電コード(Ｂ)を後方の縁材(46)から引き出すことが可能となり、弱電コード(Ａ)と強電コード(Ｂ)が混線して、弱電コード(Ａ)が強電コード(Ｂ)からノイズの影響を受けるのが防止される。
さらに、各コード(Ａ)(Ｂ)を前方の縁材(46)及び後方の縁材(46)から整然とした状態で引き出すことができるので、見栄えがよくなる。
【００４１】
ダクトカバー(43)は、係合溝(44)に把持部(17)を弾性係合させて、下面を支持面(15)に載置するだけで、簡単かつ確実にダクト保持部材(11)に取り付けることができ、かつ、取外しも簡単に行うことができる。
【００４２】
本実施形態のダクトカバー(43)の縁材(46)は、可撓性のある軟質の合成樹脂製であるが、これを、獣毛または化学繊維等の可撓性のある繊維をダクトカバー(43)の前後面に植設したブラシ状のもの（図示略）としてもよく、このような縁材を用いても、ダクト部材(33)内の配線コードを、体裁良くダクトカバー(43)の上方に引き出すことができる。
【００４３】
また、天板(６)と幕板(７)との間に形成された開口(８)の直下に、ダクト部材(33)を止めねじ等を用いることなく、簡単に着脱することができるとともに、ダクト部材(33)は、天板(６)及び幕板(７)に確実に両持ち支持されたダクト保持部材(11)に前後及び下面を支持されるので、ダクト部材(33)に多量の配線コード（図示略）を載せた場合でも、ダクト部材(33)が変形して、配線コードがダクト部材(33)からこぼれ落ちることはない。
底板(35)に設けた配線挿通孔(34)や隙間(42)を利用すれば、ダクト部材(33)の中間部や隙間(42)から、配線コードを下方に引き出すことができる。
【００４４】
本実施形態では、ダクト部材(33)(51)に係合爪(40)を形成し、ダクト保持部材(11)に係止孔(29)(30)を形成しているが、ダクト部材(33)(51)に係止孔(29)(30)を穿設し、ダクト保持部材(33)(51)に係合爪(40)を突設してもよい。
【００４５】
【発明の効果】
請求項１記載の発明によると、ダクトカバーの下面を、配線ダクトの底部に設けたカバー支持部によって支持するので、ダクトカバーの縁部を開口の縁部に係止させる必要がなくなり、その結果、ダクトカバーの両側縁または全周縁に、配線コード引出し用の軟質の縁材を設けることが可能となる。
また、ダクトカバーの上面に電気機器等が載置された場合にあっても、ダクトカバーが撓んだりすることはない。
さらに、ダクト保持部材が、ダクトカバーの支持とダクト部材の取り付けの両方の機能を兼ねるので、部品点数の削減を図ることができるとともに、ダクト部材の構造を単純なものとすることができる。
【００４６】
請求項２記載の発明によると、ダクトカバーの縁材の一部を弾性変形させて、そこから、配線コードを引き出すことができ、開口のそれ以外の部分は、ダクトカバーにより体裁よく覆っておくことができる。
【００４７】
請求項３記載の発明によると、例えば、ダクトカバーの一方の側縁部の縁材を弾性変形させて、そこから弱電コードを引き出し、かつ他方の側縁部の縁材を弾性変形させて、そこから強電コードを引き出すことが可能となり、弱電コードと強電コードが混線して、弱電コードが強電コードからノイズの影響を受けること等を防止できる。
また、各コードを前方の縁材及び後方の縁材から整然と区分した状態で引き出すことができるので、見栄えがよくなる。
【００４８】
請求項４記載の発明によると、ダクトカバーの一側縁と、開口の縁部との間に形成した隙間を利用することにより、配線コードの引き出しが一層容易となる。
【００４９】
請求項５記載の発明によると、ダクトカバーをカバー支持部に簡単かつ確実に着脱することができる。
【００５０】
請求項６記載の発明によると、ダクトカバーの下面がカバー支持部の上面に支持されるので、ダクトカバーの取付状態がさらに安定し、ダクトカバー上に重量物を載置した場合でも、ダクトカバーを撓みや変形を生じることなく、確実に支持することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for closing a cord insertion opening provided on a top plate such as a desk, a table, or a work table.
[0002]
[Prior art]
As this type of conventional one, for example, there are those described in Japanese Patent Application No. 60-22819 and Japanese Patent Application No. 10-85527.
[0003]
In the desk described in Japanese Utility Model Publication No. 60-22819, an opening is formed in the rear part of the top plate in the left-right direction, and a rear top plate that complements the opening is formed in this opening, with the rear end portion at the center. It is pivotally mounted so that it can be opened and closed, and a receiver is provided at the front of the upper end of the left and right sides of the opening. When the rear top plate is closed, the lower front end of the rear top plate is The rear top plate is supported so that it is flush with the top plate.
[0004]
A flexible soft rim material is fixed to the front edge of the rear top plate, and when the opening is closed by the rear top plate, a wiring cord for an electrical device or the like placed on the top plate Alternatively, a wiring cord disposed below the rear top plate is inserted between the edge member and the rear edge of the top plate so that it can be pulled out below or above the rear top plate.
[0005]
Japanese Patent Application No. 10-85527 describes an application specification or the like in which a box-like wiring duct unit having a wiring duct formed therein is provided behind the desk, and an upper surface opening of the wiring duct unit is provided. By placing a pair of front and rear duct covers on the periphery, the upper surface opening is closed.
Soft edge material is fixed to the rear edge part of the front duct cover and the front edge part of the rear duct cover, respectively. So that wiring cords such as electrical equipment mounted on the top plate or duct cover, and wiring cords stored in the wiring duct can be pulled out from above or below the edge of the duct cover. It has become.
[0006]
[Problems to be solved by the invention]
However, the rear top plate of Japanese Utility Model Publication No. 60-22819 is supported by the desk only at the four pivot points of the rear end and the front end, and the duct cover of Japanese Patent Application No. 10-85527 is Since the peripheral part is supported by the peripheral part of the upper surface opening of the peripheral part of the wiring duct unit, when a large load is applied, such as electrical equipment is placed on the center part of the rear top plate and the duct cover, There is a risk that the rear top plate or duct cover may be deformed.
[0007]
In addition, since the rear top of the Japanese Utility Model Publication No. 60-22819 is designed to pivot on the rear end of the rear top plate, a soft edge cannot be attached to the rear edge of the rear top plate. On the other hand, the front duct portion of Japanese Patent Application No. 10-85527 is mounted at the front edge, and the rear duct cover is mounted at the rear edge portion of the upper surface opening of the wiring duct unit. Therefore, a soft edge cannot be attached to the front edge of the front duct cover and the rear edge of the rear duct cover.
[0008]
Therefore, in the above rear top plate and the duct cover, the edge material for passing the wiring cord can be attached only to either the front or the back, and therefore, from the lower space of the rear top plate or the wiring duct. When connecting the wiring cord to the top of the desk or wiring duct unit and connecting it to electrical equipment mounted on the top plate, etc., between the edge material and the rear edge of the top plate, or between the edge materials In this case, the position where the wiring cord is drawn out is limited, and the wiring cord may be concentrated at a specific location. Therefore, for example, a high-power cord such as a power cord and a weak-power cord such as a cable connecting a personal computer and its mouse are mixed between the edge material and the rear edge of the top plate, or between the edge materials, The weak electric cord may be affected by noise from the high electric cord. In addition, the low-power cord and the high-power cord are easily mixed in the space below the rear top plate and in the wiring duct.
[0009]
Furthermore, since the wiring cord extending from the electrical equipment mounted on the top plate cannot be passed between the edge member and the top plate or between the edge members in an orderly manner, the appearance is deteriorated.
[0010]
Further, the rear top plate of Japanese Utility Model Publication No. 60-22819 is troublesome to attach to and detach from the desk, and the duct cover of Japanese Patent Application No. 10-85527 is simply placed on the upper surface of the wiring duct unit. Therefore, when an external force is applied, the position may shift or come off.
[0011]
In the present invention, in view of the above-mentioned problems of the prior art, even when an electric device or the like is placed on the upper surface of the duct cover that closes the opening of the top plate, the duct cover may be bent and deformed. In addition, the wiring cords of electrical equipment etc. can be pulled out in an orderly manner from the wiring duct formed under the desk to the top of the desk (or in the opposite direction). An object of the present invention is to provide a device for closing a wiring opening in a desk or the like, which can be prevented and can be easily and reliably attached to and detached from a duct cover.
[0012]
[Means for Solving the Problems]
