Description

【０００１】
【発明の属する技術分野】
本発明はデスクの組立構造に係り、特に組立てに際し工具等を一切使用することなく組立が行えるようにした簡易組立て式デスクに関する。
【０００２】
【従来の技術】
一般に事務用デスクは、左右の脚部と、その左右の脚部前方面間を適宜間隔に連結する幕板と、左右の脚部の上に連結される天板固定枠と、その上部に載置される天板等の部品からなっていて、これら各部品をビスにより締結することにより１台のデスクとして組立てられるようになっている。
【０００３】
さらに詳しく説明すると、幕板と脚部の組立てにはビス４個で締結を行い、天板固定枠と脚部の組立てもビス４個で締結を行い、天板固定枠と天板の締結には角穴と爪を利用してビスを使用しないで組立ている。
【０００４】
【発明が解決しようとする課題】
しかしながら上述したようにビスによる締結によるものでは、当然のことながらドライバー等の工具を必要とし、締結に際しては締め付けに時間がかかり、また解体についても同様であり、しかもビスは小さいために操作がやりにくいうえ途中で紛失する恐れがある等、種々の問題があった。
【０００５】
【課題を解決するための手段】
本発明は、ドライバー等の工具を一切使用することなく、しかも簡単で確実に組立てや解体が行えるようにした簡易組立て式デスクの提供を課題とするもので、その手段としてはビスの代わりにジョイナーを用い、連結される部品に設けた穴に差し込んで締結するようにしたことにある。
【０００６】
すなわち、請求項１に記載の発明は、デスクを構成する各デスク部品のうち、互いに締結可能な一方および他方のデスク部品の取付面同士に長手方向にそれぞれ配設された第１、第２の角穴を互いに重ね合わせ、それぞれの角穴にジョイナーを挿入することにより相互に固定するようにしたデスクであって、該ジョイナーは前記２つの角穴に跨がる長さを有し、その長手方向の一端側を前記第１の角穴に挿入させたとき、該角穴からの抜け止め兼他端側の一部を前記第２の角穴に挿入させる際の支点となる支点部を長手方向の中間に有するとともに前記他端側には弾力のある起立部を有していて、この起立部から延設され前記第２の角穴に挿入される挿入部分には抜け止め片を備えてなり、前記一方および他方のデスク部品の両取付面をジョイナーの支点部および抜け止め片で挟持するようにしたことを特徴とする。
【０００７】
また請求項２は請求項１に記載の発明において、前記一方のデスク部品が天板固定枠、他方のデスク部品が脚であることを特徴とし、請求項３は請求項１に記載の発明において前記一方のデスク部品が脚、他方のデスク部品が幕板であることを特徴とし、請求項４は請求項３に記載の発明において前記一方のデスク部品が脚、他方のデスク部品が幕板で、その幕板の上部をフックにより脚に吊り下げて取付けるようにし、前記ジョイナー数を下部左右の２個としたことを特徴とする。
【０００８】
さらに請求項５に記載の発明は、デスクを構成する各デスク部品のうち、互いに締結する一方のデスク部品の取付面に異形長穴を穿設し、他方のデスク部品の取付面に前記異形長穴と同形の異形長穴を同心で９０°変位させた方向に穿設し、両異形長穴にジョイナーを挿入して回転により締結させるようにしたデスクであって、該ジョイナーは前記両デスク部品を保持する軸部を有し、その一端側に前記両異形長穴に整合する形状の挿入張出し部を、他端側に回転用のレバーを備え、このレバーの先端の軸部側の面には前記一方のデスク部品の異形長穴に近接して設けられた凹部に係合する凸部を有してなり、前記軸部に一方のデスク部品および他方のデスク部品を保持したとき該凹部に該凸部を係合させて両部品を固定するようにしたことを特徴とする。
【０００９】
そして請求項６は請求項５に記載の発明において前記一方のデスク部品が脚、他方のデスク部品が天板固定枠であることを特徴とし、請求項７は請求項５に記載の発明において前記一方のデスク部品が脚、他方のデスク部品が幕板であることを特徴とする。
【００１０】
【発明の実施の形態】
以下、本発明にかかる簡易組立て式デスクを図面に示す実施の形態を参照して説明する。
【００１１】
第１の実施の形態のうち、天板固定枠と脚の締結の場合においては図１乃至図９に示すように天板固定枠１とこれに対応する脚２とを４個のジョイナー３，３，…を使用して締結するもので、図１は理解しやすいように片側半分（左側）の天板固定枠１の左端側に脚２の左端側を取付ける場合を斜視図で示し、対称となる右側は省略してある。
【００１２】
天板固定枠１の上面１ａには取付部４ａを備えた取付金具４がそれぞれスポット溶接等により固着されており、同様に脚２の上面２ａには取付部５ａを備えた２個の取付金具５がそれぞれスポット溶接等により固着されている。図中、３は脚２に後述する幕板１１を取付けるためのジョイナーである。
【００１３】
図２は天板固定枠１の上面１ａに固着された取付金具４（斜線部分）を拡大して示したもので、（Ａ）は平面図、（Ｂ）は側面図である。
図３は同じく脚２の上面２ａに固着された取付金具５（斜線部分）を拡大して示したもので、（Ａ）は平面図、（Ｂ）は側面図である。
【００１４】
図２および図３にそれぞれ示す取付金具４の取付部４ａ（この場合下面側が取付面）と取付金具５の取付部５ａ（この場合上面側が取付面）とは締結の際、互いに重ね合わせられるようになっていて、この部分にはそれぞれ長手方向に配設された２つの角穴がある。
【００１５】
その第１の角穴６，６′は、幅狭い部分と幅広い部分を持つ十字形状の穴、第２の角穴７，７′は、第１の角穴６，６′から適宜間隔を置いた位置にあって幅および長さとも第１の角穴６，６′に比較して小さい角穴となっており、脚２の取付部５ａに天板固定枠１の取付部４ａを重ね合わせると、図４に平面図、図５に側面図を示すように前記第１の角穴６，６′および第２の角穴７，７′がそれぞれ一致した状態となる。
【００１６】
前記ジョイナー３は、前記第１の角穴６，６′および第２の角穴７，７′に挿入されて天板固定枠１と脚２とを一体とするもので、プラスチックまたは金属材などで製作されている。
【００１７】
そのジョイナー３には、図６に斜視図を示すように、前記第１の角穴６の狭い方に嵌まる幅で前記２つの角穴６および７に跨がる長さを有して長手方向が上下に屈曲した形状をなす本体を備え、この本体の一端側３ａは幅方向の両側に前記角穴６の広い方に嵌まる張り出し部３ｈ，３ｈが設けられて十字形に形成され、本体の中間部分には前記角穴６の広い方に嵌まる張り出し部が本体に対して段差のある位置に設けられており、この張り出し部分がアールを持った支点部３ｃとされている。
【００１８】
この支点部３ｃは、前記一端側３ａを前記第１の角穴６に挿入させたとき、該角穴６からの抜け止めとなると共に他端側３ｂの一部を前記第２の角穴７に挿入させる際の回動支点となるものである。
【００１９】
前記他端側３ｂには、一端側３ａの本体幅から延設されて図６に示す方向では直角に垂下がった弾力のある起立部３ｄが本体幅と同じ幅を有してＵ字形に形成されており、この起立部３ｄから垂直に延設され前記第２の角穴７へ挿入される逆Ｖ字形の挿入部分３ｅとの境界部には抜け止め片３ｆが形成されている。
【００２０】
また挿入部分３ｅの他端は起立部３ｄ側方向に延在して、その先端側には挿入部分３ｅの振れを固定する振れ止め３ｇが設けられている。
【００２１】
つぎにこのジョイナー３を使用して天板固定枠１と脚２とを一体とする手順について説明する。なお、第１の角穴６′および第２の角穴７′は第１の角穴６および第２の角穴７と重なっているため、以下、角穴６′およびの角穴７′の説明は省略して角穴６、角穴７として説明する。
【００２２】
図５に示した第１の角穴６内に向けてジョイナー３を一端側３ａを下向きとして図７に示すように第１の角穴６に脚２の上面２ａに対して約３０°の角度となるように挿入する。
【００２３】
この状態からジョイナー３を第２の角穴７側に移動させると、支点部３ｃは第１の角穴６内に挿入されており、角穴６が十字形であるためにジョイナー３の支点部３ｃは角穴６の幅狭い部分に移動し、角穴６から抜け出すことができなくなる。そこで支点部３ｃが回転支点となって回動し、ジョイナー３の一端側３ａは天板固定枠１の取付金具４の上面４ａとほぼ同一高さとなるように起き上がり、反対に他端側３ｂの起立部３ｄ側から延設された挿入部分３ｅが第２の角穴７に挿入され、このとき抜け止め片３ｆが取付部５ａの下面に接触して起立部３ｄ側への抜け止めとなり、図８に示すように両取付部４，５はジョイナー３に挟まれた状態で締結される。そして同時に振れ止め３ｇは取付金具５の取付部５ａに接して固定される。
【００２４】
図中、８は天板固定枠１の上部に取り付けられた天板を示し、ジョイナー３の固定後に上部から下降させて押し込むことにより取付けられて図示の状態となる。
【００２５】
図９は取付金具４，５に取付けられたジョイナー３の平面図を示す。
【００２６】
したがって天板固定枠１と脚２とは取付金具４，５を挟んでジョイナー３の支点部３ｃと抜け止め片３ｆとにより締結され、天板固定枠１の前後左右と脚２の前後左右が４個のジョイナー３により同様にして組立てられる。
【００２７】
またこのようにして組立てられた天板固定枠１と脚２とを解体する場合には抜け止め片３ｆを取付金具４から外すように挿入部分３ｅの開放端を起立部３ｄ側に押し込むことにより弾力で第２の角穴７に挿入された挿入部分３ｅが外れ、その結果起立部３ｄが回動可能となるので、ジョイナー３を第１の角穴６に挿入したときと同じ状態となり、容易に取付金具４，５から抜き取ることができる。
【００２８】
第１の実施の形態のうち、脚と幕板との締結の場合は図１０乃至図１２に示すように脚２とこれに対応する幕板１１とを４個のジョイナー３，３，…を使用して締結するもので、図１１は理解しやすいように部分的に左右の脚２の片側（図示では左側）に幕板１１の左端側を取付ける場合を斜視図で示してあり、右半分の図示は省略してある。なお、上述した図面に示す部品と共通する部品については上述した部品と同一の符号を用いて説明は省略し異なる箇所のみ説明する。
【００２９】
図１０において脚２の内側に設けられた上下方向の取付面２ｂの上部には上下方向に配設された２つの角穴があって、上には小穴である第２の角穴７、第２の角穴７から適宜間隔を置いた下には十字形形状の大穴である第１の角穴６となっている。そして取付面２ｂの下部にも同様に第２の角穴７と第１の角穴６が設けられている。これに対して幕板１１の取付面１１ａにも脚２の取付面２ｂに重なる同じ大きさの第２の角穴７′と第１の角穴６′がそれぞれ設けられている。
【００３０】
したがって脚２の取付面２ｂに設けられた第２の角穴７と第１の角穴６と幕板１１の取付面１１ａに設けられた第２の角穴７′と第１の角穴６′とを重ね合わせて両取付面を接触させ、前記ジョイナー３を前記天板固定枠１と脚２の取付けと全く同様に挿入させるように近付ける。
【００３１】
そして図１１はジョイナー３の一端側３ａが角穴６′に挿入された状態図、図１２はジョイナー３が取付けられて締結完了した状態図で、この場合脚２と幕板１１の取付けには上下２個の左右について行うために計４個のジョイナー３が使用される。
【００３２】
また図１３は締結用のジョイナー３の数を減らすために脚２と幕板１１との間の取付けをつぎのようにしたものである。
【００３３】
すなわち、脚２の取付面２ｃの上側には縦穴１２を設け、この取付面２ｃに相対する幕板１１の取付面１１ｂには縦穴１２に係合するように取付面２ｃ側に突出して先端から垂下した形状のフック１３を設けて、取付面２ｃの下側と取付面１１ｂの下側には前記第２の角穴７と第１の角穴６および第２の角穴７′と第１の角穴６′とをそれぞれ設けている。ただしこの場合、取付面１１ｂの下側の第２の角穴７′と第１の角穴６′は取付面２ｃの下側に設けた第２の角穴７と第１の角穴６とは締結前には一致しない状態となっており、脚２の取付面２ｃの縦穴１２に幕板１１の取付面１１ｂのフック１３が係合して幕板１１が脚２に対して吊り下げられた状態に下降したとき第２の角穴７と第１の角穴６および第２の角穴７′と第１の角穴６′とは初めて高さが一致するようにしたものである。
【００３４】
したがって一致した角穴には前記ジョイナー３を取付ければ、ジョイナー３は左右１個ずつの計２個で締結が可能となる。
【００３５】
第２の実施の形態のうち、天板固定枠と脚の締結の場合は図１４に示すように天板固定枠１とこれに対応する脚２とを４個のジョイナー１４，１４，…を使用して締結するものである。
【００３６】
図１４は理解しやすいように片側半分（左側）の天板固定枠１の左端側に脚２の左端側を取付ける場合を斜視図で示してあり、対称に設けられる右側は省略してある。
【００３７】
天板固定枠１の左端上面１ａには取付面となる２個の取付金具１５が前後方向に配置され、それぞれスポット溶接等により固着されており、同様に脚２の上面２ａには取付面となる２個の取付金具１６が前後方向に配置されそれぞれスポット溶接等により固着されている。
【００３８】
各取付面は互いに重ね合わせられた状態で締結されるようになっていて、取付金具１５，１５には天板固定枠１の左右の前後端に中央の円形から角形状に両側に突出した形状をなす異形長穴１７，１７が、中心寄りに凹部１８，１８がそれぞれ設けられ、取付金具１６，１６には異形長穴１７と同形の異形長穴１７′，１７′が同心で９０°変位させた方向に設けられている。
【００３９】
そのジョイナー１４も前述の第１の実施形態に示したジョイナー３と同様にプラスチックまたは金属材製で、その形状は図１５に斜視図で示すように前記天板固定枠１と脚２との両取付面を保持する軸部１４ａがあって、この部分に取付金具１５，１６を挟み込むようになっており、軸部１４ａの一端側には前記両異形長穴１７，１７′に整合する形状の挿入張出し部１４ｂが設けられ、他端側は回転用のレバー１４ｃとなっている。このレバー１４ｃの先端の軸部１４ａ側の面（以下、裏面という）には、前記天板固定枠１の異形長穴１７に近接して設けられた凹部１８に係合する凸部１４ｄが設けられている。また凸部１４ｄと反対側にはレバー１４ｃ面にはレバー１４ｃを回転させる際のつまみとなる突起１４ｅが設けられている。
【００４０】
さらに軸部１４ａには先端部に設けた前記挿入張出し部１４ｂとレバー１４ｃ側基端との中間に、挿入張出し部１４ｂと同方向に突出した抜け止め１４ｆが設けられている。
【００４１】
つぎにこのジョイナー１４を使用して天板固定枠１と脚２とを一体とする手順を図１６乃至図１９に示す断面図を参照して説明する。
【００４２】
まず図１６において天板固定枠１の取付金具１５に設けられた異形長穴１７に、ジョイナー１４のレバー１４ｃを突起１４ｅを上向きとして軸部１４ａ先端の挿入張出し部１４ｂを合わせて挿入し、取付金具１５の表面にレバー１４ｃの裏面を接触させたのち、レバー１４ｃの突起１４ｅをつまんで９０°回転させて左右方向を向くようにすると、ジョイナー１４はレバー１４ｃの裏面と抜け止め１４ｆとの間の軸部１４ａに入った取付金具１５により上下方向が抜け止めされて図１６に示す状態となる。
【００４３】
その後、天板固定枠１を脚２の取付面に載置して明けられた異形長穴１７′にジョイナー１４の挿入張出し部１４ｂを合わせて矢印方向に挿入すると図１７に示すように脚２は挿入張出し部１４ｂと抜け止め１４ｆの間に位置するようになる。この状態からレバー１４ｃを元の位置となるように逆方向に９０°回転させると図１８に示す状態となり、ジョイナー１４の挿入張出し部１４ｂと抜け止め１４ｆとの間の軸部１４ａに取付金具１６が嵌め込まれて抜け止めされる。
【００４４】
このときレバー１４ｃの先端の凸部１４ｄは天板固定枠１の異形長穴１７に近接して設けられた凹部１８に係合するのでレバー１４ｃはこの位置で固定されるから前記軸部１４ａに一方のデスク部品である脚２はジョイナー１４を取付けて回転させることにより容易に締結固定することができる。そして上部から天板８を降ろすと図１９のように係合して締結は完了する。
【００４５】
以上は組立ての場合であるが、解体の場合はこの逆の手順を行うことにより容易に解体することができる。
【００４６】
第２の実施の形態のうち、脚と幕板の締結の場合は図２０に示すように脚２とこれに対応する幕板１１とはジョイナー１４，１４，…を４個使用して締結するもので、ジョイナー１４の挿入張出し部１４ｂが挿入される異形長穴１７，１７′の形状は図１４の場合と全く同様である。
【００４７】
ここで幕板１１には脚２の取付面２ｃに重なる取付面１１ａの裏側に２個の取付金具１９（前述した取付金具１５と同じ大きさ）が上下方向に配置され、それぞれスポット溶接等により固着されており、その取付金具１９には異形長穴１７とその下側に凹部１８がそれぞれ設けられている。
【００４８】
また脚２の取付面２ｃには異形長穴１７に対向する位置に異形長穴１７と同形の異形長穴１７′，１７′が同心で９０°変位させた方向に設けられており、異形長穴１７、１７にはジョイナー１４，１４が挿入前の状態に置かれている。
【００４９】
したがって脚と幕板の締結の場合も図１６乃至図１９と同じ手順により行うことができるので詳細説明は省略するが、天板固定枠１を脚２の締結と全く同様に４個のジョイナー１４により一体に締結されることになる。
【００５０】
なお、本発明は基本的にはデスクの組立に使用することを目的としているが、デスク以外のオフィス家具、パネル、アクセサリーなどにおける薄板同士の締結に応用して同一効果を奏することができる。
【００５１】
【発明の効果】
本発明は以上説明したように構成したから、つぎのような効果を奏する。
１）デスク部品の組立てがジョイナーの取付けにより行えるので、従来のようにビスによるネジ込みが不要となり、組立てに要する時間を大幅に短縮することができる。
【００５２】
２）組立ての際にドライバー等の工具を一切使用しないので、工具の管理が不要となる。
【００５３】
３）ビスを使用しないので従来のようにデスクの使用中にビスが緩み脱落するような不具合は発生しない。
