Description

【０００１】
【発明の属する技術分野】
本発明は、折畳み式テーブルの幕板連動装置に係わり、更に詳しくは天板と幕板を連動して折畳むことが可能な折畳み式テーブルの幕板連動装置に関するものである。
【０００２】
【従来の技術】
従来から、左右の脚体の上端部に、天板の下面両側部を上下回動可能に連結するとともに、前記天板の後部に配した幕板を天板の動作と連動させてリンク連結し、天板が略水平で幕板が略垂直な使用状態と、天板を上方へ回動させて該天板と幕板とを両脚体の後縁に沿った折畳み状態とを実現できる折畳み式テーブルは各種提供されている。
【０００３】
例えば、特許文献１には、天板の後部下面を支柱の上端部に上下回動可能に連結するとともに、天板の後方に幕板を立起状態に配し、該幕板を前記支柱に平行リンクで平行移動可能に連結するとともに、上方のリンク杆の幕板側の枢着点と天板の後端部下面との間に連動杆をリンク連結し、前記天板の上方回動に伴って幕板が下方へ平行移動する連動機構が記載されている。
【０００４】
しかし、特許文献１に記載された天板と幕板の連動機構は、使用状態から折畳み状態へ変化する際に、天板の後端部と幕板の前面との間に有する隙間が狭くなり、折畳み状態では天板の上面と幕板の前面が重合するまで接近するため、この動作の途中で前記隙間に指を挟む危険性がある。尚、前記幕板が天板よりも下方に位置する構造の場合には、天板の後端部を持って天板の折畳み動作をさせることがあるので、指詰めの危険性は更に高くなる。

【発明が解決しようとする課題】
本発明が前述の状況に鑑み、解決しようとするところは、天板と幕板を連動して折畳むことが可能な折畳み式テーブルの幕板連動装置であって、折畳み動作の途中において前記天板の後端部と幕板の上端部との間に所定間隔以上の空隙を設けて指詰めの危険性を排除した折畳み式テーブルの幕板連動装置を提供する点にある。
【０００７】
【課題を解決するための手段】
本発明は、前述の課題解決のために、左右の脚体の上端部に、天板の下面両側部を上下回動可能に主軸にて連結するとともに、前記天板の後部下方に配した幕板を、天板後部下方に接近して垂下した使用状態と両脚体の後縁に沿った折畳み状態との間を移動可能に前記天板と連動させることが可能な折畳み式テーブルの幕板連動装置であって、前記主脚の上部内面側に取付凹部を形成し、該取付凹部に前記支持板の下部に形成したクランク状の取付台部を内側方からネジ止めするとともに、左右の主脚にそれぞれ取付けた両支持板の取付台部間に連結ビームを固着し、更に前記支持板に主軸にて前記天板を回動可能に連結し、前記天板の後部下方に配した幕板を、左右両側において一対の上下リンク杆にて前記支持板にリンク連結するとともに、該上リンク杆と天板後部とを連動杆にてリンク連結して天板と幕板とを連動させ、前記天板と幕板の一連の折畳み動作中に常に天板後端部と幕板上端部との間に所定間隔以上の空隙を形成すべく、前記上下リンク杆及び連動杆の長さと枢着位置を設定してなる折畳み式テーブルの幕板連動装置を構成した。
【０００９】
また、前記幕板を前記脚体の後縁に沿って折畳んだ側面視状態において、該幕板とそれに対応する前記脚体の後縁の形状を後方へ突出した湾曲形状に略一致させてなるとより好ましい。
【００１０】
更に、前記幕板を前記脚体の後縁に沿って折畳んだ側面視状態において、前記上下リンク杆が前記脚体の内側に略隠蔽されてなると更に好ましい。
【００１１】
【発明の実施の形態】
次に本発明の実施の形態を添付図面に基づき更に詳細に説明する。本発明の脚装置は、広く一般のテーブルや机に適用できるものであるが、本実施形態では折畳み式テーブルに適用した例で説明する。図１は、本実施形態の折畳み式テーブルを背後から見た使用状態における全体斜視図、図２は同じく使用状態における側面図、図３は折畳み状態における側面図、図４及び図５は脚装置の詳細を示している。図中符号Ａは脚装置、Ｂは幕板連動装置、Ｃはロック装置、１は脚体、２は天板、３は幕板をそれぞれ示している。
【００１２】
本実施形態の折畳み式テーブルは、左右の脚体１，１の上端部に、天板２の下面両側部を上下回動可能に連結し、該天板２を略水平な使用状態（図２参照）と上方へ回動させた折畳み状態（図３参照）とに変更することができるとともに、前記天板２の後部下方に配した幕板３を、天板２後部下方に接近して垂下した使用状態と両脚体１，１の後縁に沿った折畳み状態との間を移動可能に前記天板２と連動させてリンク連結したものであり、使用状態と折畳み状態にロック可能な構造となっている。
【００１３】
先ず、本発明に係る脚装置Ａ（脚体１）は、図１〜図５に示すように、前記天板２の両側部を支持する脚装置であって、主脚４と該主脚４の前方に配する単又は複数種類の中から選んだ補助脚５とからなり、前記主脚４の上下中間部に補助脚５の上端部を着脱可能に連結したものである。
【００１４】
具体的には、図４及び図５に示すように、前記脚体１は、前記補助脚５を連結する前記主脚４の連結部６の前面側に螺孔７，７を形成し、前記補助脚５の上端部に主脚４の連結部６の前面側から側面側に係合する係合部８を形成するとともに、前記螺孔７，７に対応する係合部８に取付孔９，９を形成し、前記連結部６に係合部８を係合させた状態で前面側からネジ１０，１０を取付孔９，９に挿通し且つ螺孔７，７に螺合してなるのである。
【００１５】
ここで、前記連結部６は、前記係合部８を嵌合する凹部となすとより連結が強固である。前記係合部８は、前記主脚４の前面側に接合し、前記取付孔９，９を形成した前面部８ａと、前記前記主脚４の側面側に接合する側面部８ｂとから平面視略Ｌ字形に形成されている。そして、前記ネジ１０，１０によって補助脚５の係合部８の前面部８ａを主脚４の連結部６に引き付けて取付けるが、前記側面部８ｂが主脚４の側面部に当接していることにより、前記補助脚５の外側への変位が規制されるのである。尚、前記ネジ１０，１０は補助脚５の内側に位置し、前面側から主脚４に螺合するので、外側面から見えなくなって外観性の向上が図れる。また、前記補助脚５の係合部８は、その他の部分よりも大きく設定しているため、前記連結部６との接触面積が多くなり、連結状態が安定になるとともに、係合部８による側方への突出が少ないので、足等をぶっつけても怪我をする心配がないのである。
【００１６】
前記脚体１を構成する主脚４と補助脚５は、本実施形態ではアルミニウム製であり、主脚４と補助脚５を分離したことによって成形金型が小さくなって、安くなるので、製造コストを低減することができる。また、前記補助脚５は、前後寸法の異なる複数種類を用意しておけば、前記天板２の奥行幅に応じて選択し、それを前記主脚４に連結し、安定な支持状態を低コストで実現できる。つまり、奥行幅が異なる折畳み式テーブルの商品群を用意するのに、共通の主脚４を用いて、補助脚５のみを異なる寸法のものと組合わせれば良いので、トータルコストの低減化が図れるのである。例えば、図２に示した折畳み式テーブルは、奥行幅が６０ｃｍ天板２と、中間長さの補助脚５の組合せ構成例、図６（ａ）は奥行幅が４５ｃｍの天板２ａと、短い補助脚５ａの組合せ構成例、図６（ｂ）は奥行幅が７０ｃｍの天板２ａと、長い補助脚５ａの組合せた構成例である。また、前記補助脚５は、寸法を違える以外にも、色を替えたものを複数種用意することも可能である。その場合には、色彩デザイン上において好みの色を選択したり、変化を持たせることができる。
【００１７】
また、側面視において、前記主脚４は後方へ突出して緩やかに湾曲した形状であり、前記補助脚５は前方へ突出して緩やかに湾曲した形状であり、該補助脚５は前方になるにつれて僅かに外側に開き、左右の両補助脚５，５間に前方に位置する折畳み式テーブルの両主脚４，４が嵌まり込み、前後にスタッキング可能にしている。また、前記主脚４と補助脚５の下端には、それぞれキャスター１１，…を取付けて移動可能としている。そして、複数の折畳み式テーブルをスタッキングする際に、前方の折畳み式テーブルの補助脚５の内面と後方の折畳み式テーブルの主脚４の外面が擦れるが、その際に摺動性を高めるとともに、接触による傷付きを防止するために、前記補助脚５の内側面の頂部に沿ってポリオレフィン系ゴム等の保護部材１２を添設している。具体的には、前記補助脚５の内側面に凹溝を形成しておき、この凹溝内に保護部材１２の大半部を埋め込んで固定する。尚、前記保護部材１２は、主脚を受入れる際の摺動及び緩衝作用を有する材質であれば適宜採用でき、また補助脚５への取付け構造も接着やネジ止めなど固定手段は問わない。
【００１８】
このように、前記脚体１は、主脚４に対して補助脚５が着脱可能となっているため、梱包や保管時にコンパクトにすることができる。図７は、前記天板２を上方へ回動させるとともに、前記幕板３を主脚４の後縁に沿って配した折畳み状態において、前記補助脚５を主脚４から外した状態を示している。ここで、前記天板２と主脚４及び幕板３は、略直線上に位置するので、後述の幕板連動装置Ｂやロック装置Ｃを分解しなくても全体の厚さが非常に薄いものとなり、扁平な箱で梱包することができる。また、前記補助脚５、５は、両主脚４，４間に収容して梱包することができるので、嵩張らないのである。
【００１９】
ここで、図３及び図７に示すように、前記幕板３を前記脚体１の主脚４の後縁に沿って折畳んだ側面視状態において、該幕板３とそれに対応する前記脚体１の主脚４の後縁の形状を後方へ突出した湾曲形状に略一致させてなると、強度的に弱い幕板３の両側縁を主脚４で保護することになり、折畳み状態あるいは梱包状態においても該幕板３が変形することがなくなる。また、図１及び図２の使用状態において、幕板３は天板２の後端部に位置し、主脚４よりも大きく後退した位置にあるので、足入れ空間を広く使用できるにもかかわらず、前記幕板３が後方へ突出した湾曲形状であるので、その下部が天板２の下方により深く隠れるので、近くを通行の際に足を幕板３の下縁に引っ掛ける恐れも少なくなる。
【００２０】
また、図４及び図５に示すように、前記主脚４の前記連結部６より上部内面側に取付凹部１３を形成し、該取付凹部１３に肉厚が厚い強度の高い支持板１４の下部に形成したクランク状の取付台部１５を内側方からネジ止めするとともに、左右の主脚４，４にそれぞれ取付けた両支持板１４，１４の取付台部１５，１５間に連結ビーム１６を固着し、両支持板１４，１４を該連結ビーム１６で一体化して強度を高めている。それにより、左右の主脚４，４は、前記連結ビーム１６を介して一体に連結されて支持強度が非常に高いものとなっている。
【００２１】
次に、幕板連動装置Ｂについて、図２、図３及び図８に基いて説明する。この幕板連動装置Ｂは、左右の脚体１，１の上端部に、天板２の下面両側部を上下回動可能に主軸１７にて連結するとともに、前記天板２の後部下方に配した幕板３を、天板２後部下方に接近して垂下した使用状態と両脚体１，１の後縁に沿った折畳み状態との間を移動可能に前記天板２と連動させてリンク連結し、前記天板２と幕板３の一連の折畳み動作中に常に天板２の後端部１８と幕板３の上端部１９との間に所定間隔以上の空隙２０を形成したものである。
【００２２】
ここで、所定間隔以上の前記空隙２０を設けることにより、前記天板２の後端部１８を持って該天板２の上下方向に回動させる際に、不意に天板２の後端部１８と幕板３の上端部１９との間で指を挟むことを防止するのである。また、折畳み状態において、前記幕板３が両脚体１，１の主脚４，４の後縁に沿うので、スタッキングした場合に前後の収納効率を高めることができる。
【００２３】
具体的には、前記天板２の後部下方に配した幕板３を、左右両側において一対の上下リンク杆２１，２２にて脚体１にリンク連結するとともに、該上リンク杆２１と天板２後部とを連動杆２３にてリンク連結して天板２と幕板３とを連動させ、前記天板２と幕板３の一連の折畳み動作中に常に天板２の後端部１８と幕板３の上端部１９との間に所定間隔以上の空隙２０を形成すべく、前記上下リンク杆２１，２２及び連動杆２３の長さと枢着位置を設定したのである。
【００２４】
ここで、前述のように、前記幕板３を前記脚体１の主脚４の後縁に沿って折畳んだ側面視状態において、該幕板３とそれに対応する前記脚体１の主脚４の後縁の形状を後方へ突出した湾曲形状に略一致させ、更に前記幕板３を前記脚体１の主脚４の後縁に沿って折畳んだ側面視状態において、前記上下リンク杆２１，２２が前記脚体１の内側に略隠蔽されて、殆ど見えないようにしている。
【００２５】
前述のように、前記上下リンク杆２１，２２及び連動杆２３の長さと枢着位置を設定するには、先ず前記天板２の動作に連動して要求される前記幕板３の使用状態での位置と折畳み状態での位置を決定する。それから、前記幕板３の両側背面位置での前記上リンク杆２１と下リンク杆２２を枢着する第１枢着点２４、第２枢着点２５を決定する。そして、前記幕板３が使用状態と折畳み状態にあるときの前記第１枢着点２４，２４から等距離の点を前記主脚４の内側面上に決定し、この点を第３枢着点２６とし、同様に前記第２枢着点２５，２５から等距離の位置に第４枢着点２７を設定する。それにより、第１枢着点２４と第３枢着点２６を両端に有する前記上リンク杆２１の長さが決定され、また第２枢着点２５と第４枢着点２７を両端に有する前記下リンク杆２２の長さが決定される。ここで、前記上リンク杆２１は、折畳み状態において前記連結ビーム１６を逃がすために、若干湾曲した形状となっている。そして、前記天板２の後部下面の適所に第５枢着点２８を仮決めし、使用状態と折畳み状態における該第５枢着点２８から等距離にある上リンク杆２１の中間部近傍の点を決定し、この点を第６枢着点２９とし、第５枢着点２８と第６枢着点２９を両端に有する前記連動杆２３の長さが決定される。このように、各枢着点２４〜２９の位置が決定され、上下リンク杆２１，２２及び連動杆２３の長さと形状が決定された状態で、前記天板２を使用状態から折畳み状態に変化させ、その変化の途中で前記空隙２０が所定間隔以下になる場合には、前述の設定作業をやり直し、前記天板２と幕板３の一連の折畳み動作中に常に所定間隔以上の空隙２０が形成されるまで繰り返す。それにより、使用状態と折畳み状態における天板２と幕板３の位置は設計どおりになることが保証されているので、折畳み動作中に常に所定間隔以上の空隙２０が確保できたらそれで設定作業は終了する。また、前記第３枢着点２６と第４枢着点２７は、前記支持板１４の取付台部１５に設けてあり、従って主脚４に支持板１４を取付ける前に上下リンク杆２１，２２は組立てることができる。
【００２６】
次に、図２、図３、図９〜図１１に基いて、前記ロック装置Ｃを説明する。このロック装置Ｃは、左右の脚体１，１の上端部に、天板２の下面両側部を上下回動可能に連結し、該天板２を略水平な使用状態と上方へ回動させた折畳み状態とに固定する折畳み式テーブルのロック装置Ｃであって、前記脚体１に設けた支持板１４に主軸１７にて前記天板２を回動可能に連結するとともに、該支持板１４の縁部に第１係合部３０と第２係合部３１を形成し、前記天板２の下面の両側部にそれぞれ上下傾動可能に配した規制部材３２の先端部に突設した規制部３３が、使用状態時に前記第１係合部３０に係合し、折畳み状態時に前記第２係合部３１に係合すべく該規制部材３２をキックばね３４にて弾性付勢するとともに、該規制部材３２の基端部に設けた操作片３５に当接して、前記規制部３３が第１係合部３０又は第２係合部３１から離れる方向に前記規制部材３２を操作する操作部材３６を、天板２の下面の両側部にそれぞれ回動可能に設けたものである。
【００２７】
ここで、前記規制部材３２は、枢軸３７にて傾動可能となし、該規制部材３２とは別体の操作部材３６が支軸３６Ａにて回動可能に設けられている。そして、前記天板２の下面の両側部に設けた両操作部材３６，３６は、その支軸３６Ａ，３６Ａが一本のシャフト３８の両端部に固定され連動して回動するようになっている。前記操作部材３６は、レバー３９と前記規制部材３２の操作片３５に当接する押圧片４０を有し、前記レバー３９を持ち上げることによって、前記押圧片４０が操作片３５を下方に押し、それにより前記規制部材３２のピン状の前記規制部３３がキックばね３４の弾性付勢力に抗して、第１係合部３０又は第２係合部３１から離れ、前記天板２の前縁部等の適所を持って上方に回動させたり、下方へ回動させて状態を変化させるのである。この状態変化の途中では前記レバー３９から手を離しても良く、前記規制部３３が支持板１４の円弧状端縁４１を摺動するのである。
【００２８】
更に具体的には、図９及び図１０に示すように、前記天板２の下面両側部に前後方向に溝部４３を向けて、下方へ開放した断面略コ字形の取付部材４２を取付けるとともに、前記脚体１の上端部に取付けた支持板１４の上部を前記取付部材４２の溝部４３内に配して該取付部材４２の両側壁板４４に主軸１７にて回動可能に連結し、更に前記規制部材３２及び操作部材３６を前記取付部材４２に回動可能に設けている。そして、前記取付部材４２は、合成樹脂製のカバー４５で覆われている。
【００２９】
前記規制部材３２と操作部材３６とを別体で形成し、左右の操作部材３６，３６をシャフト３８で連動させたことにより、左右何れの側の操作部材３６を操作させても両方の規制部材３２，３２を操作することができ、しかも部材精度や取付精度が多少悪くても確実に操作することができる。しかも、最も重要な前記規制部材３２の前記規制部３３が第１係合部３０又は第２係合部３１に係合してロックする動作は、前記キックばね３４の弾性付勢力によってそれぞれ独立して動作するので、確実に使用状態と折畳み状態とに状態を固定できるのである。
【００３０】
また、図２及び図３において、図中符号４６は、天板２の後部下面に取付けた配線ダクトである。この配線ダクト４６は、使用状態において側面視略Ｌ字形の受部の前縁を立ち上げた形状を有し、前方に向かって開放したものである。この配線ダクト４６に前方からコードを配線した状態で、図３に示すように折畳み状態としてもコードが落下することはない。また、前記空隙２０が存在するので、コードを該空隙２０を通して配線したまま、折畳み動作を行ってもコードが断線する恐れがないのである。
【００３１】
【発明の効果】
以上にしてなる請求項１に係る折畳み式テーブルの幕板連動装置は、左右の脚体の上端部に、天板の下面両側部を上下回動可能に主軸にて連結するとともに、前記天板の後部下方に配した幕板を、天板後部下方に接近して垂下した使用状態と両脚体の後縁に沿った折畳み状態との間を移動可能に前記天板と連動させることが可能な折畳み式テーブルの幕板連動装置であって、前記主脚の上部内面側に取付凹部を形成し、該取付凹部に前記支持板の下部に形成したクランク状の取付台部を内側方からネジ止めするとともに、左右の主脚にそれぞれ取付けた両支持板の取付台部間に連結ビームを固着し、更に前記支持板に主軸にて前記天板を回動可能に連結し、前記天板の後部下方に配した幕板を、左右両側において一対の上下リンク杆にて前記支持板にリンク連結するとともに、該上リンク杆と天板後部とを連動杆にてリンク連結して天板と幕板とを連動させ、前記天板と幕板の一連の折畳み動作中に常に天板後端部と幕板上端部との間に所定間隔以上の空隙を形成すべく、前記上下リンク杆及び連動杆の長さと枢着位置を設定してなるので、天板後端部と幕板上端部との間に所定間隔以上の空隙を確実に確保することができ、折畳み動作の途中において前記天板の後端部と幕板の上端部との間に指を挟む恐れが全くなく、安全に折畳み操作を行うことができる。そして、主脚に支持板を取付ける前に上下リンク杆は組立てることができる。また、前記空隙を利用してコードを配線することができ、しかも空隙にコードを挿通して配線したまま折畳み操作をしてもコードが挟まれることがなく、よって断線の恐れがないのである。また、上リンク杆と天板下面とを連動杆でリンク連結するので、天板の動作を増幅して幕板を動作させることができ、天板と重ならないように幕板を脚体に沿って折畳むことができる。また、前記主脚の上部内面側に取付凹部を形成し、該取付凹部に前記支持板の下部に形成したクランク状の取付台部を内側方からネジ止めするとともに、左右の主脚にそれぞれ取付けた両支持板の取付台部間に連結ビームを固着し、更に前記支持板に主軸にて前記天板を回動可能に連結してなるので、両支持板を連結ビームで一体化して強度の高い構造となっており、左右の主脚は、支持板に取付けることで、連結ビームを介して一体に連結され、支持強度が非常に高い構造となっている。
【００３３】
請求項２によれば、折畳み状態においてよりコンパクトになるとともに、強度の弱い幕板を脚体が保護するので、不意に幕板が変形したり、破損したりする恐れが少なくなる。
【００３４】
請求項３によれば、外観性に優れたものになるばかりでなく、不必要にリンク機構が露出しないので、このリンク機構部に指を挟む危険性が低くなる。

BACKGROUND OF THE INVENTION
The present invention relates to a curtain-plate interlocking device for a folding table, and more particularly to a curtain-plate interlocking device for a folding table that can be folded in conjunction with a top plate and a curtain.
[0002]
[Prior art]
Conventionally, both upper and lower sides of the top plate are connected to the upper ends of the left and right legs so that the bottom plate can be turned up and down, and a curtain plate arranged at the rear of the top plate is linked in conjunction with the operation of the top plate. Folding type that can realize a use state in which the top plate is substantially horizontal and the curtain plate is substantially vertical, and the top plate and the curtain plate are folded along the rear edges of both legs by rotating the top plate upward. Various tables are provided.
[0003]
For example, in Patent Document 1, the rear lower surface of the top plate is connected to the upper end of the column so as to be vertically rotatable, and a curtain plate is arranged in a standing state behind the top plate, and the curtain plate is attached to the column. A parallel link is used to enable translational movement, and an interlocking rod is linked between the pivot point on the curtain plate side of the upper link rod and the lower surface of the rear end of the top plate so that the top plate can be rotated upward. Accordingly, an interlocking mechanism is described in which the curtain plate translates downward.
[0004]
However, the interlocking mechanism between the top plate and the curtain plate described in Patent Document 1 has a narrow gap between the rear end of the top plate and the front surface of the curtain plate when changing from the use state to the folded state. In the folded state, since the top surface of the top plate and the front surface of the curtain plate come close to each other, there is a risk that a finger may be caught in the gap during this operation. In the case of the structure in which the curtain plate is positioned below the top plate, the top plate may be folded by holding the rear end portion of the top plate, so that the risk of finger padding is further increased. .
[0005]
[Patent Document 1]
JP-A-9-266819 [0006]
[Problems to be solved by the invention]
In view of the above situation, the present invention intends to solve a curtain-table interlocking device for a folding table that can fold a top-plate and a curtain, in the middle of a folding operation. The object is to provide a curtain plate interlocking device for a folding table in which a gap of a predetermined distance or more is provided between the rear end portion of the plate and the upper end portion of the curtain plate to eliminate the danger of finger padding.
[0007]
[Means for Solving the Problems]

Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The leg device of the present invention can be widely applied to general tables and desks. In the present embodiment, an example in which the leg device is applied to a folding table will be described. FIG. 1 is an overall perspective view of the foldable table according to the present embodiment as viewed from behind, FIG. 2 is a side view of the foldable table, FIG. 3 is a side view of the foldable state, and FIGS. Details are shown. In the figure, symbol A is a leg device, B is a curtain plate interlocking device, C is a lock device, 1 is a leg, 2 is a top plate, and 3 is a curtain plate.
[0012]
The foldable table of this embodiment is connected to the upper ends of the left and right legs 1, 1 so that both sides of the lower surface of the top plate 2 can be turned up and down, and the top plate 2 is used in a substantially horizontal state (FIG. 2). (See FIG. 3) and a folded state (see FIG. 3) rotated upward, and the curtain plate 3 arranged below the rear portion of the top plate 2 approaches the lower portion of the rear portion of the top plate 2 and hangs down. The link between the used state and the folded state along the rear edges of both legs 1, 1 is linked to the top plate 2 so as to be movable, and can be locked in the used state and the folded state. It has become.
[0013]
First, a leg device A (leg body 1) according to the present invention is a leg device that supports both side portions of the top plate 2, as shown in FIGS. The auxiliary leg 5 is selected from a single or a plurality of types disposed in front of the main leg 4, and the upper and lower intermediate parts of the main leg 4 are detachably connected to the upper end part of the auxiliary leg 5.
[0014]
Specifically, as shown in FIGS. 4 and 5, the leg 1 is formed with screw holes 7 and 7 on the front side of the connecting portion 6 of the main leg 4 that connects the auxiliary leg 5, and An engaging portion 8 that engages from the front side to the side surface of the connecting portion 6 of the main leg 4 is formed at the upper end portion of the auxiliary leg 5, and an attachment hole 9 is formed in the engaging portion 8 corresponding to the screw holes 7, 7. , 9 are formed, screws 10 and 10 are inserted into the mounting holes 9 and 9 from the front side and screwed into the screw holes 7 and 7 with the engaging part 8 engaged with the connecting part 6. It is.
[0015]
Here, if the connecting portion 6 is a recess into which the engaging portion 8 is fitted, the connection is stronger. The engagement portion 8 is joined to the front surface side of the main leg 4 to form a plan view from a front surface portion 8a formed with the mounting holes 9 and 9, and a side surface portion 8b joined to the side surface side of the main leg 4. It is formed in a substantially L shape. The front surface 8a of the engaging portion 8 of the auxiliary leg 5 is attached to the connecting portion 6 of the main leg 4 by the screws 10 and 10, and the side surface 8b is in contact with the side surface of the main leg 4. As a result, the outward displacement of the auxiliary leg 5 is restricted. The screws 10 and 10 are located inside the auxiliary leg 5 and screwed into the main leg 4 from the front side, so that they cannot be seen from the outer side and the appearance can be improved. Further, since the engaging portion 8 of the auxiliary leg 5 is set larger than the other portions, the contact area with the connecting portion 6 is increased, the connected state is stabilized, and the engaging portion 8 is used. Because there are few protrusions to the side, there is no worry of injury even if you hit your feet.
[0016]
The main leg 4 and the auxiliary leg 5 constituting the leg body 1 are made of aluminum in this embodiment, and the molding die becomes smaller and cheaper due to the separation of the main leg 4 and the auxiliary leg 5. Cost can be reduced. If a plurality of types of auxiliary legs 5 having different front and rear dimensions are prepared, the auxiliary legs 5 are selected according to the depth width of the top plate 2 and connected to the main legs 4 to reduce the stable support state. It can be realized at a cost. That is, in order to prepare a product group of folding tables having different depth widths, it is only necessary to use the common main leg 4 and combine only the auxiliary legs 5 with different dimensions, so that the total cost can be reduced. It is. For example, the folding table shown in FIG. 2 is a combination configuration example of the top plate 2 having a depth width of 60 cm and the auxiliary legs 5 having an intermediate length, and FIG. 6A is a short top plate 2a having a depth width of 45 cm. FIG. 6B is a configuration example in which the top plate 2a having a depth width of 70 cm and a long auxiliary leg 5a are combined. Further, the auxiliary legs 5 can be prepared in a plurality of types with different colors other than having different dimensions. In that case, it is possible to select a favorite color on the color design or to have a change.
[0017]
Further, in a side view, the main leg 4 has a shape that protrudes backward and is gently curved, and the auxiliary leg 5 has a shape that protrudes forward and is gently curved, and the auxiliary leg 5 slightly increases toward the front. The two main legs 4 and 4 of the foldable table located in front of the left and right auxiliary legs 5 and 5 are fitted into each other so that they can be stacked in the front-rear direction. Further, casters 11,... Are attached to the lower ends of the main leg 4 and the auxiliary leg 5, respectively, so as to be movable. And when stacking a plurality of foldable tables, the inner surface of the auxiliary leg 5 of the front foldable table and the outer surface of the main leg 4 of the rear foldable table are rubbed, and at that time, while improving the slidability, In order to prevent damage due to contact, a protective member 12 such as polyolefin rubber is provided along the top of the inner side surface of the auxiliary leg 5. Specifically, a concave groove is formed on the inner side surface of the auxiliary leg 5, and the most part of the protective member 12 is embedded and fixed in the concave groove. The protective member 12 can be appropriately adopted as long as it is a material having a sliding and buffering action when receiving the main leg, and the attachment structure to the auxiliary leg 5 may be any fixing means such as adhesion or screwing.
[0018]
In this way, the leg 1 can be made compact during packaging and storage because the auxiliary leg 5 can be attached to and detached from the main leg 4. FIG. 7 shows a state in which the auxiliary leg 5 is removed from the main leg 4 in a folded state in which the top plate 2 is rotated upward and the curtain plate 3 is arranged along the rear edge of the main leg 4. ing. Here, since the top plate 2, the main leg 4, and the curtain plate 3 are positioned on a substantially straight line, the overall thickness is very thin without disassembling the curtain plate interlocking device B and the lock device C described later. It becomes a thing and can be packed in a flat box. The auxiliary legs 5 and 5 are not bulky because they can be accommodated and packed between the main legs 4 and 4.
[0019]
Here, as shown in FIGS. 3 and 7, the curtain plate 3 and the leg corresponding thereto are viewed in a side view when the curtain plate 3 is folded along the rear edge of the main leg 4 of the leg 1. If the shape of the rear edge of the main leg 4 of the body 1 is made to substantially coincide with the curved shape protruding rearward, both side edges of the weakly strong curtain plate 3 will be protected by the main leg 4, and it will be folded or packaged. Even in the state, the curtain plate 3 is not deformed. 1 and 2, the curtain plate 3 is located at the rear end portion of the top plate 2 and is in a position retracted more than the main leg 4, so that the foot space can be widely used. Since the curtain plate 3 has a curved shape protruding rearward, the lower part of the curtain plate 3 is hidden deeper below the top plate 2, so that the possibility of catching a foot on the lower edge of the curtain plate 3 when passing nearby is reduced. .
[0020]
As shown in FIGS. 4 and 5, a mounting recess 13 is formed on the inner surface of the main leg 4 above the connecting portion 6, and the mounting recess 13 is thick at the bottom of the high strength support plate 14. The crank-shaped mounting base 15 formed in the above is screwed from the inner side, and the connecting beam 16 is fixed between the mounting bases 15 and 15 of the both support plates 14 and 14 attached to the left and right main legs 4 and 4, respectively. The two support plates 14 and 14 are integrated by the connecting beam 16 to increase the strength. As a result, the left and right main legs 4 and 4 are integrally connected via the connecting beam 16 and have very high support strength.
[0021]
Next, the curtain plate interlocking device B will be described with reference to FIGS. This curtain-plate interlocking device B is connected to the upper ends of the left and right legs 1 and 1 by connecting the lower side portions of the top plate 2 with a main shaft 17 so as to be vertically rotatable and arranged below the rear portion of the top plate 2. The linked curtain plate 3 is linked to the top plate 2 so as to be movable between a use state in which the curtain 3 is suspended close to the rear lower part of the top plate 2 and a folded state along the rear edges of both legs 1, 1.

Then, a point equidistant from the first pivot points 24 and 24 when the curtain 3 is in the use state and the folded state is determined on the inner surface of the main leg 4, and this point is the third pivot point. Similarly, a fourth pivot point 27 is set at a position equidistant from the second pivot points 25, 25. Accordingly, the length of the upper link rod 21 having the first pivot point 24 and the third pivot point 26 at both ends is determined, and the second pivot point 25 and the fourth pivot point 27 are disposed at both ends. The length of the lower link rod 22 is determined. Here, the upper link rod 21 has a slightly curved shape in order to escape the connecting beam 16 in the folded state. Then, a fifth pivot point 28 is provisionally determined at an appropriate position on the lower surface of the rear portion of the top plate 2, and in the vicinity of the middle portion of the upper link rod 21 that is equidistant from the fifth pivot point 28 in the use state and the folded state. A point is determined, and this point is set as the sixth pivot point 29, and the length of the interlocking rod 23 having the fifth pivot point 28 and the sixth pivot point 29 at both ends is determined. In this way, with the positions of the pivot points 24 to 29 being determined and the lengths and shapes of the upper and lower link rods 21 and 22 and the interlocking rod 23 being determined, the top plate 2 is changed from the use state to the folded state. If the gap 20 becomes less than the predetermined interval during the change, the above setting operation is repeated, and the gap 20 always exceeds the predetermined interval during the series of folding operations of the top plate 2 and the curtain plate 3. Repeat until formed. As a result, the positions of the top plate 2 and the curtain plate 3 in the used state and the folded state are guaranteed to be as designed, so if the gap 20 of a predetermined interval or more can always be secured during the folding operation, then the setting work is finish. Further, the third pivot point 26 and the fourth pivot point 27 are provided on the mounting base 15 of the support plate 14, so that the upper and lower link rods 21 and 22 are attached before the support plate 14 is attached to the main leg 4.
