Description

【０００１】
【発明の属する技術分野】
本発明は、住宅や事務所の部屋、トイレ、風呂場等の三角コーナ部の壁面に取付けて使用されるコーナ棚に関するものである。
【０００２】
【従来の技術】
部屋等の三角コーナ部の壁面にコーナ棚を取付ける通常の方法は、Ｌ字形金具などを用いて、コーナ壁面にコーナ棚を釘付けしたり、ネジ締めしたりする方法である。しかしこの取付け方法では、別部材のＬ字形金具などを用いるため、取付け作業が煩雑になると共に、見栄えが悪いという問題があり、特にコーナ壁面からコーナ棚を取り外す作業が困難であるという問題があった。
【０００３】
このような問題点を解消するため、従来より、Ｌ字形金具などの別部材を用いることなく、比較的簡便にコーナ壁面に対する取付け、取外し作業を行えるコーナ棚が提案されている（例えば、特許文献１参照。）。
【０００４】
この従来例は図２２に示すように、コーナ棚本体５１にスライド可能に収容されると共に先端に針５２を備えた左右の針付きスライダ５３を有し、コーナ棚本体５１の裏面に設けた操作つまみ５４を回転させることにより、この回転動作をベベルギヤ５５、回転シャフト５６等を介して左右の針付きスライダ５３の進退動に変換するように構成したものである。この従来例によれば、前記操作つまみ５４を正方向に回転することにより、左右の針付きスライダ５３を外方に移動させて、これらの針５２をコーナ壁面に突き刺してコーナ棚を取付けることができ、また前記操作つまみ５４を逆方向に回転することにより、左右の針付きスライダ５３を内方に移動させて、これらの針５２をコーナ壁面から抜き取り、コーナ棚を取り外すことができる。

【発明が解決しようとする課題】
しかしながら、上記従来例では、操作つまみ、ベベルギヤ、回転シャフト等を棚本体の外側に設ける必要があって、構造が複雑で高価になると共に、操作つまみ等の部材が外観されて見栄えが悪くなるという問題があった。また針付きスライダをコーナ壁面に突き刺すために大きな力を要するのであるが、そのためには操作つまみ１回転当りの針付きスライダの移動量を小さく設定する必要があって、コーナ棚の取付け・取外しを完了するまでには操作つまみを多数回回転させなければならず、作業に比較的長い時間を要するという問題もあった。そしてこのような点から棚本体が大きなものには適していないし、上記取付け方法では、コーナ壁面に接するように棚本体の左右取付面を保持しながら操作つまみを回す動作は大変しずらく、こうした点からも棚本体の大きさは比較的小さなものに適しているし、様々な大きさのものを作製するにはそれだけの品揃えが必要になり、コストがかかるという問題もあった。
【０００７】
そこで本発明は上記問題点に鑑み、コーナ壁面への取付け、取外し作業を迅速に行うことができ、構造簡単で、コストをかけずに自由な大きさに形成できるコーナ棚を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明のコ−ナ棚は上記目的を達成するため、コーナ壁面に接する左右取付面に左右斜辺が位置する平面視ほぼ台形状で、組合せて棚本体部となるように分割された複数の棚部材と、各棚部材にスライド可能に収容されると共に先端に針を備えた左右の針付きスライダと、各棚部材に正面から挿脱可能に挿入される操作板とを備え、操作板の表面には押出し用カムが、裏面には引込み用カムがそれぞれ形成され、操作板の表面を上下の一方側に向けて棚部材内に挿入して押動すると、前記押出し用カムにより左右の針付きスライダが外方に移動してそれぞれの針が前記左右取付面の外方に突出し、操作板の裏面を前記上下の一方側に向けて棚部材内に挿入して押動すると、前記引込み用カムにより左右の針付きスライダが内方に移動してそれぞれの針が前記左右取付面の内方に退入するように構成したことを特徴とする。
【０００９】
上記発明によれば、従来では１部材からなるコーナ棚の棚本体部が、複数の棚部材に分割されているので、棚部材の数をいくつ組合せるかによってコーナ棚の大きさを自由に形成でき、様々な大きさのコーナ棚を品揃えする必要がないのでコストがかからない。また、操作板の棚部材への挿入押動操作によって、左右の針付きスライダを進退動させるだけで、コーナ棚の取付け・取外し作業を容易に行うことができると共に、複数の棚部材を組合せただけのシンプルな構造でこの点においてもコスト的に有利である。さらに、操作板に形成した押出し用カムや引込み用カムを利用して、操作板の押動操作で針付きスライダの進退動を行うので、コーナ棚の取付け・取外し作業を迅速に行うことができる。そして、これら操作のための部材が殆ど外観されないので意匠的にも優れている。また、１枚の操作板に押出し用カムと引込み用カムとが形成されているので、構造の一層の簡単化と低コスト化を図ることができる。
【００１０】
上記発明において、各棚部材は奥行がほぼ同じに形成し、操作板は、１つの棚部材の針付きスライダを内外に進退動可能に操作しうる長さに形成すると、操作板を棚部材の奥行とほぼ同じ長さとすることができ、棚部材の取付け・取外し作業を順次行い易く、操作板の長さによってコーナ棚の奥行が限定されず、様々な大きさのものにも対応できる。
【００１１】
上記発明において、各棚部材には、正面の中央部からコーナ奥方向に貫通して操作板ガイド穴を形成し、操作板を、複数の棚部材が組合された棚本体部の奥行とほぼ同じ長さに形成すると、全ての棚部材を取付けた後に、操作板を棚本体部内に連通した操作板ガイド穴に挿入した状態で、棚本体部の中央部を貫通する補強材として機能するので好適である。
【００１２】
本発明のコーナ棚の形成方法は上記目的を達成するため、コーナ壁面に接する左右取付面に左右斜辺が位置する平面視ほぼ台形状で、組合せて棚本体部となるように分割された複数の棚部材と、各棚部材にスライド可能に収容されると共に先端に針を備えた左右の針付きスライダと、押出し用カムが形成されて各棚部材に正面から挿脱可能に挿入される操作板とを用い、コーナ奥に棚部材を配置し、この棚部材に操作板を挿入して押出し用カムにより左右の針付きスライダを外方に移動させ、針をコーナ壁面に刺し込んだ後に操作板を抜き取り、次いで前記棚部材の手前側の棚部材に前記操作板を挿入して前記針付きスライダの針をコーナ壁面に刺し込み、その後、さらに手前側の棚部材にも同じ動作を順次行うことによって、複数の棚部材をコーナ奥から手前方向に連続してあるいは間隔をおいてコーナ壁面に取付けてコーナ棚を形成することを特徴とする。
【００１３】
上記発明によれば、請求項１記載のコーナ棚と同様の作用効果を奏することができると共に、その取付け作業を分割された棚部材に対し複数回に分けて行うので、棚部材を保持しながらの配置や操作が容易であり、大きなコーナ棚を形成する場合に十分に対応できる。ここで、複数の棚部材を連続して取付ければ棚本体部の上下面が面一となった平面視台形状のコーナ棚が形成できるし、間隔をおいて取付ければ簀の子状で輪郭が平面視台形状のコーナ棚が形成できる。また、連続して取付けた場合には棚部材どうしが連結されるが、その連結面（正面と背面）を凹凸嵌合とすれば、その嵌合により上下動が規制されるので、取付作業が容易になるので好適である。尚、請求項１記載のコーナ棚では、１枚の操作板に押出し用カムと引込み用カムとを形成しているが、このコーナ棚の形成方法では多少この点を犠牲にして、引込み用カムが形成された取外し用操作板とは別に、押出し用カムのみが形成された取付け用操作板を用いることも可能である。
【００１４】
また、請求項４記載の方法にて形成されたコーナ棚を、引込み用カムが形成されて各棚部材に正面から挿脱可能に挿入される操作板を用いて取外す方法として、最も手前側の棚部材に操作板を挿入し、引込み用カムにより左右の針付きスライダを内方に移動させてコーナ壁面に刺し込まれた針を左右取付面の内方に退入させ、次いで前記棚部材の奥の棚部材に前記操作板を挿入して前記針付きスライダの針を左右取付面の内方に退入させ、その後、さらに奥の棚部材にも同じ動作を順次行うことによって、コーナ壁面に取付けられた複数の棚部材を手前からコーナ奥側に向けて取外すことを特徴とする。
【００１５】
上記発明によれば、取付け作業とは逆に針付きスライダの針を退入させる引込み用カムが形成された操作板を同じようにして棚部材に挿入するだけで、コーナ棚の取外し作業を容易かつ迅速に行うことができる。尚、例えば、請求項２記載の操作板を用いれば、棚本体に対して１つづつ抜き取りと押し込み動作を繰り返し、各針付きスライダの針を退入させてコーナ棚を取外していく方法を採るが、請求項３記載の操作板を用いれば、組合せられた棚部材（棚本体部）から操作板を抜き取った後、引込み用カムと押出し用カムの両方を兼ねる操作板であればひっくり返して、最も手前側の棚部材に挿入して針を内方に退入させた後、操作板を抜き取ることなく前記棚部材を保持したままで、前記操作板をそのまま押動して次の棚部材に挿入する動作を順次行う方法も、場合によっては可能となる。
【００１６】
【発明の実施の形態】
以下、本発明の実施形態について、図面を参照しながら説明する。
【００１７】
（第１実施形態）
図１〜図６、図１６において、１は平面視形状が左右斜辺の長さが等しい台形で板状の棚部材（総称するときは１とし、複数のものを区別するときは１Ａ、１Ｂ、１Ｃとする。）を示している。棚部材１は、上板２と下板３とを接着一体化して構成され、奥行（前記台形の高さ）が同じで幅が異なる複数のものに分割されて、これらが組合せられて従来は１部材であった棚本体部を構成する。これら複数の棚部材１Ａ、１Ｂ、１Ｃがコーナ奥から手前方向に連続して取付けられて各棚部材１Ａ、１Ｂ、１Ｃが連結され、図１６のコーナ棚完成図に示すような平面視台形状のコーナ棚が形成される。
【００１８】
棚部材１の側周に位置する左右の面は、コーナ壁面４Ｌ、４Ｒに接する左取付面５Ｌ、右取付面５Ｒとなっていて、この左右取付面５Ｌ、５Ｒに前記台形の左右斜辺が位置している。尚、コーナ壁面４Ｌ、４Ｒは図示するような９０度の三角コーナ部に限定されず、その形状に対応して棚部材１は左右斜辺の長さが違っていても良く、平面視ほぼ台形状であれば良い。前記棚部材１の側周の前側（前記台形の底辺）に位置する正面６ａには、操作板７を挿脱可能に案内する操作板ガイド穴８が、正面６ａの中央部からこれに直交するコーナ奥方向に貫通して設けられている。
【００１９】
左取付面５Ｌには左針付きスライダ９Ｌをスライド可能に案内する左案内穴１０Ｌが、左取付面５Ｌに開口するようにして設けられている。右取付面５Ｒには右針付きスライダ９Ｒをスライド可能に案内する右案内穴１０Ｒが、右取付面５Ｒに開口するようにして設けられている。図１に示すように、左案内穴１０Ｌと右案内穴１０Ｒとは、正面６ａに平行に一直線上に位置するように設けられ、それぞれの内端は前記操作板ガイド穴８に交わってこれと連通している。上記２つの案内穴１０Ｌ、１０Ｒは、横断面形状が同一の長方形状である。なお、棚部材１の上面１３および下面１４は平坦面に形成されている。
【００２０】
前記上板２は樹脂板からなり、その下面に前記操作板ガイド穴８、各案内穴１０Ｌ、１０Ｒ等を構成するための凹凸部が一体形成されている。前記下板３は樹脂板からなり、その上面に前記操作板ガイド穴８等を構成するための凹凸部が一体形成されている。
【００２１】
前記操作板７は樹脂で構成され、図５〜図８等に示すように、略長方形の基板部１５と、その表面側に隆起形成された押出し用カム１６と、基板部１５の裏面側に隆起形成された引込み用カム１７とからなり、棚部材１の奥行より若干長く形成され、棚部材１の正面６ａから前記操作板ガイド穴８に挿脱可能に挿入しうるように構成されている。つまり操作板７は、１つの棚部材１の針付きスライダ９Ｌ、９Ｒを内外に進退動可能な長さに形成されれば、棚部材１の奥行とほぼ同じに形成することもできる。
【００２２】
前記押出し用カム１６は、図５に示すように、操作板７の中心線に対し左右対称の略Ｔ形状の板状カムであって、基端側に広幅部１９を有すると共に先端側に鋭角の二等辺三角部２１を有し、その２辺がカム面（カム面部）１８、１８となっている。また押出し用カム１６の広幅部１９の近傍位置には指掛け用凹部２０が形成されている。
【００２３】
前記引込み用カム１７は、図６に示すように、操作板７の中心線に対し左右対称の略Ｕ形状の板状カムであって、基端辺部２２と左右の側辺部２３、２３とからなり、両側辺部２３、２３の先端部の内面側が斜めに切欠かれたカム面（カム面部）２４、２４となっている。両カム面２４、２４は先端側に向けてハ字状に開き、両者のなす角は鋭角となっている。
【００２４】
前記押出し用カム１６の広幅部１９の左右端および前記引込み用カム１７の両側辺部２３、２３の左右端に対し前記基板部１５の左右端がそれぞれ側方に張り出した位置にあり、図５等に示すようにこの左右の張出部２５、２５が棚部材１の操作板ガイド穴８の両内側面に設けた溝２６、２６に嵌合するようになっている。
【００２５】
前記操作板７の基端面２７の形状は、図２、図３、図５に示すように、横長の長方形を基本形状とし、その両側面に前記張出部２５、２５が突出する形状となっているが、棚部材１の操作板ガイド穴８の横断面形状も同様の形状となっていて、操作板７が操作板ガイド穴８に案内されてスムースに前後動できるように構成されている。また図１に示すように、操作板７を操作板ガイド穴８に挿入したとき、操作板７の基端面２７が棚部材１の正面６ａと面一となるように構成されている。
【００２６】
操作板ガイド穴８の左右、つまり正面６ａとコーナ奥側に位置する背面６ｂにはそれぞれ連結用凹部１２Ｌ、１２Ｒと連結用凸部１１Ｌ、１１Ｒが設けられている。両者は凹凸嵌合によって連結されるが、図１６で示せば、コーナ最奥の棚部材１Ａの連結用凹部１２Ｌ、１２Ｒには、その手前に位置する棚部材１Ｂの連結用凸部１１Ｌ、１１Ｒが嵌合され、棚部材１Ａに棚部材１Ｂが連結される。同様にして棚部材１Ｂの連結用凹部１２Ｌ、１２Ｒに棚部材１Ｃの連結用凸部１１Ｌ、１１Ｒが嵌合され、棚部材１Ｂに棚部材１Ｃが連結される。尚、コーナ最奥の棚部材１Ａの背面には連結用凸部１１Ｌ、１１Ｒを設ける必要はなく、最も手前側の棚部材には連結用凹部を設ける必要はない（図１６に示すコーナ棚の最も手前側にある棚部材１Ｃは、連結用凹部１２Ｌ、１２Ｒが設けられているので、さらに幅の大きい棚部材を連結することも可能である。）。
【００２７】
棚部材１の下面１４の正面側左右方向中央には、図４に示すように、切欠窓部２８を設け、前記指掛け用凹部２０や前記基端辺部２２を利用して、操作板７を引き出しやすくしている。
【００２８】
前記左針付きスライダ９Ｌは、図１、図７〜図１１に示すように、樹脂製のスライダ本体２９の外端面３０に植設された２本の金属製の針３１、３１を備えると共に、内端側下面にカム従動用突部３２を一体に備えている。尚、コーナ最奥用の棚部材１Ａは、針３１、３１が１本でも良い。
【００２９】
前記スライダ本体２９の横断面形状は、棚部材１の左案内穴１０Ｌのそれと同一の長方形状となっている。そして前記左針付きスライダ９Ｌは、図１に示すように、前記左案内穴１０Ｌ内に左右動自在に収容され、その左右動によって前記針３１、３１が棚部材１の左取付面５Ｌから出没するように構成されている。前記針３１、３１が図６等に示すように、最大限外部に突出するとき、スライダ本体２９の外端面３０が前記左取付面５Ｌと面一となるよう、外端面３０は斜面に形成されている。
【００３０】
前記スライダ本体２９の内端側部分は、図７、図９に示すように下面側が抉られて薄肉部３３となっており、この薄肉部３３の下面に前記カム従動用突部３２が円柱状に一体形成されている。スライダ本体２９の薄肉部３３以外の部分の下面と、前記カム従動用突部３２の下端面とは同一高さ位置にある。
【００３１】
前記右針付きスライダ９Ｒは、前記左針付きスライダ９Ｌと左右対称な形状に形成され、同様に２本の針３１、３１、カム従動用突部３２を備え、同様に前記右案内穴１０Ｒ内に左右動自在に収容されている。
【００３２】
次に、前記操作板７の挿入押動操作と各針付きスライダ９Ｌ、９Ｒの動きの関係につき説明する。尚、本実施形態では、複数の棚部材１でコーナ棚を形成するためにコーナ最奥の棚部材の取付け作業を最初に行うが、図面では図１〜図４で示したようにコーナ奥から２番目の棚部材１を１例にして、説明することとする。
【００３３】
前記操作板７を図５、図１２、図１３に示すように、押出し用カム１６が形成された表面を上側にして、前記操作板ガイド穴８に挿入して押動すると、各針付きスライダ９Ｌ、９Ｒのカム従動用突部３２に押出し用カム１６のカム面１８、１８が当接して、各針付きスライダ９Ｌ、９Ｒを左右方向外方に移動させ、それぞれの針３１が棚部材１の左右取付面５Ｌ、５Ｒの外方に突出するように構成されている。図１２は、各針付きスライダ９Ｌ、９Ｒが退入位置にあって、棚部材１に挿入された操作板７の押出し用カム１６のカム面１８、１８が左右針付きスライダ９Ｌ、９Ｒのカム従動用突部３２に当接する直前の状態を示している。この状態からさらに操作板７を前進させると、図１３に示すように、操作板７を棚部材１の奥行まで挿入した状態では、左右針付きスライダ９Ｌ、９Ｒは押出し用カム１６によって左右方向外方に移動させられ、これらの外端面３０が棚部材１の左右取付面５Ｌ、５Ｒと面一となる位置に達し、これらの針３１は完全に外方に突出する。
【００３４】
一方、前記操作板７を図１、図６、図１４、図１５に示すように、引込み用カム１７が形成された裏面を上側にして、前記操作板ガイド穴８に挿入して押動すると、各針付きスライダ９Ｌ、９Ｒのカム従動用突部３２に引込み用カム１７のカム面２４、２４が当接して、各針付きスライダ９Ｌ、９Ｒを左右方向内方に移動させ、それぞれの針３１が棚部材１の左右取付面５Ｌ、５Ｒの内方に退入するように構成されている。図１４は、各針付きスライダ９Ｌ、９Ｒが突出位置にあって、棚部材１に挿入された操作板７の引込み用カム１７のカム面２４、２４が前側の左右針付きスライダ９Ｌ、９Ｒのカム従動用突部３２に当接する直前の状態を示している。この状態からさらに操作板７を前進させると、図１５に示すように、操作板７を棚部材１に貫通させた状態では、左右針付きスライダ９Ｌ、９Ｒは引込み用カム１７によって左右方向内方に移動させられ、最内方に達し、これらの針３１は棚部材１の左右取付面５Ｌ、５Ｒの内方に退入する。
【００３５】
なお操作板７の挿入押動操作によって、各針付きスライダ９Ｌ、９Ｒの上記移動がスムースになされるよう、各カム面１８、２４と各カム従動用突部３２との位置関係等が、図面に示すように、適正に定められている。また上記実施形態では、操作板７の挿入方向と各針付きスライダ９Ｌ、９Ｒの移動方向とが直交する関係となっているが、直交しなくてもよい。
【００３６】
次に、上記構成のコーナ棚を形成しつつ部屋の三角コーナ部の壁面４Ｌ、４Ｒに取付ける作業について説明する。
【００３７】
先ず、一番幅の小さいコーナ最奥用の棚部材１Ａを、その左右取付面５Ｌ、５Ｒがコーナ壁面４Ｌ、４Ｒに接するように配置して保持し、次いで押出し用カム１６が形成された表面を上側に向けて操作板７を棚部材１の正面６ａの操作板ガイド穴８に挿入して押し込む。この押し込み力によって図１２、図１３で説明したように、各針付きスライダ９Ｌ、９Ｒは左右方向外方に移動し、各々の針３１がコーナ壁面４Ｌ、４Ｒに刺し込まれて棚部材１Ａがコーナ壁面４Ｌ、４Ｒに取付けられ、コーナ棚の一部（最奥部）が形成される。通常のコーナ壁面４Ｌ、４Ｒに対しては、操作板７の押動力が押出し用カム１６の増力作用（カム面１８、１８間のなす角が小さい程、増力倍率が大となる。）によって増大されるので、人の押し込み力だけで前記作業を行うことができる。尚、コーナ壁面４Ｌ、４Ｒが硬い材質のものである場合などは、木ハンマーなどによって操作板７を打ち込むことによって、前記取付け作業を行えばよい。
【００３８】
次いで、棚部材１Ａから操作板７を抜き取り、棚部材１Ａの手前側の棚部材１Ｂの連結用凸部１１Ｌ、１１Ｒを、棚部材１Ａの連結用凹部１２Ｌ、１２Ｒに嵌入すると共に、その左右取付面５Ｌ，５Ｒがコーナ壁面４Ｌ、４Ｒに接するように配置して保持する。この際、連結用凸部１１Ｌ、１１Ｒと連結用凹部１２Ｌ、１２Ｒの嵌合によって上下動が規制されるので、取付作業が容易になる。そして前記抜き取った操作板７を、棚部材１Ｂの正面６ａより操作板ガイド穴８へ挿入して押し込む。この操作板７の抜き取り、棚部材１の連結と保持、操作板７の挿入・押込みによる取付作業を順次、手前の棚部材１に対して行い、複数の棚部材１Ａ〜１Ｃをコーナ奥から手前に向けて連続して形成してコーナ壁面４Ｌ、４Ｒに取付ける。尚、本実施形態では、連結用凸部１１Ｌ、１１Ｒと連結用凹部１２Ｌ、１２Ｒの嵌合によって、棚部材１Ａ〜１Ｃを連結してその表面が面一となった棚本体部を形成したが、各棚部材１Ａ〜１Ｃを間隔を置いて取付けて、輪郭が平面視台形状で簀の子状のコーナ棚を形成しても良い。
【００３９】
上記のようにしてコーナ棚の形成および取付作業が終了すると、最も手前側の棚部材１Ｃ内に挿入された操作板７はそのまま収容され、その基端面２７は棚部材１Ｃの正面６ａと面一状態になり、見栄えが悪くなるのを防ぐと共に、コーナ棚の取外し作業時にすぐに使える状態にしておくことができる。
【００４０】
次に、上記のようにして形成したコーナ棚を前記コーナ壁面４Ｌ、４Ｒから取外す作業について説明する。
【００４１】
先ず、最も手前側の棚部材１Ｃに収容されている操作板７を前記操作板ガイド穴８から抜き取る。次いで操作板７の上下を逆にして、引込み用カム１７が形成された裏面を上側に向けて操作板７を前記操作板ガイド穴８に挿入して押し込む。この押し込み力によって図１４、図１５および図１で説明したように、各針付きスライダ９Ｌ、９Ｒは左右方向内方に移動し、各々の針３１は壁面４Ｌ、４Ｒから抜け、コーナ棚の手前部分を形成する棚部材１Ｃの取外し作業を行うことができる。次いで、棚部材１Ｃから抜き取った操作板７をそのままの状態で棚部材１Ｃより奥の棚部材１Ｂに挿入して押し込むと、上記同様にして各々の針３１は壁面４Ｌ、４Ｒから抜け、棚部材１Ｂが取外される。その後同様にして、棚部材１Ｂから操作板７を抜き取って、棚部材１Ｂの取外しを行う。この取外し作業は、一旦コーナ壁面４Ｌ、４Ｒに刺し込まれた針３１を抜き取るだけでよく、抜き取るための力はそれほど大きなものは必要ではないので人の押し込み力だけで十分である。
【００４２】
本実施形態のコーナ棚は図１６に示すように、棚部材１Ａ、１Ｂ、１Ｃの左右取付面５Ｌ、５Ｒが面一に連なる斜面を形成し、平面視台形状に形成される。
【００４３】
このコーナ棚は、従来では１部材からなる棚本体部が棚部材１Ａ、１Ｂ、１Ｃに分割されているので、組合せる棚部材の数によって、コーナ棚の大きさを自由に形成できるので、様々な大きさのコーナ棚を品揃えする必要がないのでコストがかからない。また、操作板７の棚部材１への挿入押動操作によって、左右の針付きスライダ９Ｌ、９Ｒを進退動させるだけで、コーナ棚の取付け・取外し作業を容易に行うことができると共に、複数の棚部材１を組合せただけのシンプルな構造でこの点においてもコスト的に有利である。さらに、操作板７に形成した押出し用カム１６や引込み用カム１７を利用して、操作板７の押動操作で針付きスライダ９Ｌ、９Ｒの進退動を行うので、コーナ棚の取付け・取外し作業を迅速に行うことができる。そして、これら操作のための部材が殆ど外観されないので意匠的にも優れている。尚、本実施形態では、１枚の操作板７に押出し用カム１６と引込み用カム１７とが形成されているので、構造の一層の簡単化と低コスト化を図ることができるが、操作板７を押し出用と引込み用の２枚に分けることも可能である。
【００４４】
上記実施形態において、図１７および図１８に示すように、コーナ棚の表面にには化粧カバー３４が取付けられている。図１７は化粧カバー３４の斜視図、図１８は化粧カバー３４を取付けたコーナ棚を、コーナ壁面から見た状態の側面図であり、４Ｓはコーナ奥部である。化粧カバー３４は、アルミ板やプラスチック板に木目模様や大理石模様をプリントした化粧合板からなる薄板を用い、上面３４ａはコーナ棚の平面視台形状に合わせて同形状に形成し、上面３４ａと正面３４ｂと一部の下面３４ｃでコーナ棚を覆う形状に形成されている。尚、下面３４ｃはコーナ棚の手前だけを覆う形状にした方が、化粧カバー３４の取付け・取外しに便利であるが、コーナ棚の下面全体を覆うように上下面同一に形成することも可能である。この化粧カバー３４により、図１６に示すような複数の棚部材１を連結した連結部が外観されず、また棚部材１を間隔を置いて組合せた場合には、その間隔が外観されずに意匠性が向上するので好適である。
【００４５】
（第２実施形態）
図１９に示す第２実施形態は、操作板７Ａとして、複数の棚部材１Ａ〜１Ｃを組合せた棚本体部の奥行より若干長く形成された（針付きスライダ９Ｌ、９Ｒの進退動が可能であれば前記奥行とほぼ同じ長さでも良い。）ものを用いたコーナ棚を示している。操作板７Ａを用いた取付け作業では、その前端部を用いて第１実施形態で説明した方法と同様にして行うが、全ての棚部材１Ａ〜１Ｃを取付けた後に、操作板７Ａを棚本体部内に連通した操作板ガイド穴８に挿入した状態で、棚本体部の中央部を貫通する補強材として機能するので好適である。そして取外し作業では、棚部材１Ａ〜１Ｃから操作板７Ａを抜き取った後は、引込み用カム１７が形成された裏面を上側にして、最も手前側の棚部材１Ｃに挿入して針３１、３１を内方に退入させた後、第１実施形態で示した棚部材１の奥行とほぼ同じ長さの操作板７を用いた場合と同様にして、操作板７Ａの抜き取りながら押し込み操作を順次行っても良いが、操作板７Ａを抜き取ることなく、棚部材１Ｃを保持したままで、操作板７Ａをさらに押し込んで棚部材１Ｃより奥の棚部材１Ｂに挿入する動作を順次行う方法も、場合によっては可能となる。
【００４６】

BACKGROUND OF THE INVENTION
The present invention relates to a corner shelf used by being attached to a wall surface of a triangular corner portion of a room of a house or office, a toilet, a bathroom, or the like.
[0002]
[Prior art]
The usual method of attaching a corner shelf to the wall surface of a triangular corner portion of a room or the like is a method of nailing the corner shelf to the corner wall surface using an L-shaped bracket or the like, or screwing it. However, since this mounting method uses an L-shaped metal fitting or the like as a separate member, there are problems that the mounting work becomes complicated and the appearance is poor, and in particular, it is difficult to remove the corner shelf from the corner wall surface. It was.
[0003]
In order to solve such a problem, conventionally, a corner shelf has been proposed that can be attached to and detached from a corner wall relatively easily without using another member such as an L-shaped bracket (for example, Patent Documents). 1).
[0004]
As shown in FIG. 22, this conventional example has left and right needle-attached sliders 53 that are slidably accommodated in a corner shelf main body 51 and are provided with needles 52 at the tips, and are provided on the rear surface of the corner shelf main body 51. By rotating the knob 54, this rotating operation is converted into the forward / backward movement of the left and right needle-attached sliders 53 via the bevel gear 55, the rotating shaft 56, and the like. According to this conventional example, by rotating the operation knob 54 in the forward direction, the left and right needle sliders 53 are moved outwardly, and these needles 52 are pierced into the corner wall surface to attach a corner shelf. In addition, by rotating the operation knob 54 in the opposite direction, the left and right needle-attached sliders 53 can be moved inward, and these needles 52 can be removed from the corner wall surface and the corner shelf can be removed.
[0005]

[0006]
[Problems to be solved by the invention]
However, in the above conventional example, it is necessary to provide an operation knob, a bevel gear, a rotating shaft, etc. on the outside of the shelf body, and the structure is complicated and expensive. There was a problem. In addition, a large force is required to pierce the slider with the needle into the corner wall. To that end, it is necessary to set a small amount of movement of the slider with the needle per one rotation of the operation knob. The operation knob had to be rotated many times until completion, and there was a problem that a relatively long time was required for the work. From this point of view, it is not suitable for a large shelf body, and in the above mounting method, it is very difficult to turn the operation knob while holding the left and right mounting surfaces of the shelf body so as to contact the corner wall surface. From the point of view, the size of the shelf body is suitable for a relatively small size, and in order to produce various sizes, there is a problem in that an assortment of products is required and the cost is high.
[0007]
SUMMARY OF THE INVENTION In view of the above problems, the present invention has an object to provide a corner shelf that can be quickly attached to and detached from a corner wall surface and can be formed in a free size with a simple structure and without cost. And
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the corner shelf of the present invention has a substantially trapezoidal shape in plan view in which left and right oblique sides are positioned on left and right mounting surfaces in contact with a corner wall surface, and a plurality of shelves that are divided so as to be combined into a shelf main body. A member, a slider with left and right needles that are slidably accommodated in each shelf member and provided with a needle at the tip, and an operation plate that is removably inserted into each shelf member from the front. Is formed with a push-out cam, and a pull-in cam is formed on the back side. When the front surface of the operation plate is inserted into the shelf member and pushed up and down, the push-out cam has left and right needles. When the slider moves outward, the respective needles protrude outward from the left and right mounting surfaces, and when the back surface of the operation plate is inserted into the shelf member toward the upper and lower sides and pushed, the retracting cam The left and right needle sliders move inward Needle Les is characterized by being configured such that retracts inward of the left and right mounting surface.
[0009]
According to the above invention, since the shelf main body portion of the corner shelf made up of one member is conventionally divided into a plurality of shelf members, the size of the corner shelf can be freely formed depending on how many shelf members are combined. This is not necessary because there is no need to stock various corner shelves. Also, by simply pushing the left and right sliders forward and backward by inserting and pushing the operation plate into the shelf member, the corner shelf can be easily attached and removed, and a plurality of shelf members are combined. This is a simple structure and is advantageous in terms of cost. Furthermore, since the slider with a needle is moved forward and backward by pushing the operation plate using the push-out cam and the pull-in cam formed on the operation plate, the corner shelf can be quickly installed and removed. . And since the member for these operations is hardly visible, it is excellent also in design. Further, since the pushing cam and the retracting cam are formed on one operation plate, the structure can be further simplified and the cost can be reduced.
[0010]
In the above invention, each shelf member is formed to have substantially the same depth, and the operation plate is formed to have a length that allows the slider with a needle of one shelf member to be moved forward and backward. The length can be almost the same as the depth, the shelf members can be easily attached and removed sequentially, the depth of the corner shelf is not limited by the length of the operation plate, and it can be adapted to various sizes.
[0011]
In the above invention, each shelf member is formed with an operation plate guide hole penetrating from the front central portion in the corner depth direction, and the operation plate is substantially the same as the depth of the shelf body portion in which the plurality of shelf members are combined. If it is formed in length, it is suitable because it functions as a reinforcing material that penetrates the central part of the shelf main body in a state where the operation plate is inserted into the operation plate guide hole communicating with the inside of the shelf main body after attaching all the shelf members. It is.
[0012]
In order to achieve the above object, a method for forming a corner shelf of the present invention has a substantially trapezoidal shape in plan view in which left and right oblique sides are positioned on left and right mounting surfaces in contact with a corner wall surface, and is combined with each other to form a shelf main body. A shelf member, a slider with left and right needles that are slidably accommodated in each shelf member and provided with a needle at the tip, and an operation plate that is inserted into each shelf member so as to be removably inserted from the front. , A shelf member is placed at the back of the corner, an operation plate is inserted into the shelf member, the left and right needle sliders are moved outward by the push cam, and the operation plate is inserted after the needle is inserted into the corner wall surface. Then, the operation plate is inserted into the shelf member on the near side of the shelf member, the needle of the slider with the needle is inserted into the corner wall surface, and then the same operation is sequentially performed on the shelf member on the near side. By multiple shelf members From the corner back attached to the corner wall at a continuously or distance toward the body and forming a corner shelf.
[0013]
According to the said invention, while having the same effect as the corner shelf of Claim 1, since the attachment operation | work is divided | segmented into multiple times with respect to the divided | segmented shelf member, holding a shelf member Is easy to arrange and operate, and can sufficiently handle the case where a large corner shelf is formed. Here, if a plurality of shelf members are continuously attached, a corner shelf having a trapezoidal shape in a plan view in which the upper and lower surfaces of the shelf main body are flush with each other can be formed. A corner shelf having a trapezoidal shape in plan view can be formed. In addition, when mounted continuously, the shelf members are connected to each other. However, if the connecting surfaces (front and back) are concave and convex, the vertical movement is restricted by the fitting, so the mounting work is Since it becomes easy, it is suitable. In the corner shelf according to claim 1, the pushing cam and the retracting cam are formed on one operation plate. However, in this corner shelf forming method, the retracting cam is somewhat sacrificed. It is also possible to use an attachment operation plate on which only the pushing cam is formed, in addition to the removal operation plate on which is formed.
[0014]
Further, as a method of removing the corner shelf formed by the method according to claim 4 by using an operation plate in which a pull-in cam is formed and removably inserted into each shelf member from the front, The operation plate is inserted into the shelf member, the left and right needle sliders are moved inward by the retracting cam, and the needle inserted into the corner wall surface is retracted into the left and right mounting surfaces. By inserting the operation plate into the back shelf member and retracting the needle of the slider with needle into the inner side of the left and right mounting surfaces, and then sequentially performing the same operation on the back shelf member, The plurality of attached shelf members are removed from the front toward the corner back side.
[0015]
According to the above invention, it is easy to remove the corner shelf by simply inserting the operation plate on which the retracting cam for retracting the needle of the slider with the needle is inserted into the shelf member in the same manner as in the attaching operation. And can be done quickly. For example, when the operation plate according to claim 2 is used, a method of repeatedly removing and pushing the shelf main body one by one and retracting the needles of the sliders with each needle to remove the corner shelf is adopted. However, if the operation plate according to claim 3 is used, after the operation plate is extracted from the combined shelf member (shelf main body portion), it is turned over if the operation plate serves as both the retracting cam and the pushing cam. After inserting the needle into the frontmost shelf member and retracting the needle inward, the operation plate is pushed as it is without removing the operation plate, and the next shelf member is pushed In some cases, it is possible to sequentially perform the operation of inserting into the frame.
[0016]

[0032]
Next, the relationship between the insertion / pushing operation of the operation plate 7 and the movement of the sliders 9L and 9R with needles will be described. In the present embodiment, in order to form a corner shelf with a plurality of shelf members 1, the mounting operation of the shelf member at the innermost corner is first performed, but in the drawings, as shown in FIGS. The second shelf member 1 will be described as an example.
[0033]
As shown in FIGS. 5, 12, and 13, when the operation plate 7 is inserted and pushed into the operation plate guide hole 8 with the surface on which the push cam 16 is formed facing upward, each slider with a needle The cam surfaces 18 and 18 of the push cam 16 come into contact with the cam follower protrusions 32 of 9L and 9R, and the sliders 9L and 9R with needles are moved outward in the left and right directions. The left and right mounting surfaces 5L and 5R are configured to protrude outward. 12 shows that the sliders 9L and 9R with needles are in the retracted positions, and the cam surfaces 18 and 18 of the push cam 16 of the operation plate 7 inserted into the shelf member 1 are cams of the sliders 9L and 9R with left and right needles. The state immediately before contacting the driven projection 32 is shown. When the operation plate 7 is further advanced from this state, the sliders 9L and 9R with left and right needles are moved outward in the left-right direction by the pushing cam 16 in a state where the operation plate 7 is inserted to the depth of the shelf member 1 as shown in FIG. These outer end surfaces 30 reach positions where they are flush with the left and right mounting surfaces 5L, 5R of the shelf member 1, and these needles 31 protrude completely outward.
[0034]
On the other hand, when the operation plate 7 is inserted and pushed into the operation plate guide hole 8 with the back surface on which the retracting cam 17 is formed facing upward as shown in FIGS. 1, 6, 14, and 15. Then, the cam surfaces 24, 24 of the retracting cam 17 come into contact with the cam follower protrusions 32 of the sliders 9L, 9R with needles, and the sliders 9L, 9R with needles are moved inward in the left-right direction. 31 is configured to retract into the left and right mounting surfaces 5L, 5R of the shelf member 1. FIG. 14 shows that the sliders 9L and 9R with needles are in the projecting positions, and the cam surfaces 24 and 24 of the retracting cam 17 of the operation plate 7 inserted in the shelf member 1 have the left and right needle-attached sliders 9L and 9R. The state immediately before coming into contact with the cam follower protrusion 32 is shown. When the operation plate 7 is further advanced from this state, the sliders 9L and 9R with left and right needles are moved inward in the left-right direction by the retracting cam 17 in a state where the operation plate 7 is passed through the shelf member 1 as shown in FIG. And reach the innermost position, and these needles 31 retreat into the left and right mounting surfaces 5L and 5R of the shelf member 1.
[0035]
The positional relationship between the cam surfaces 18 and 24 and the cam follower projections 32 is shown so that the movement of the sliders 9L and 9R with the needles can be smoothly performed by inserting and pushing the operation plate 7. As shown in the figure, it is properly determined. Moreover, in the said embodiment, although the insertion direction of the operation board 7 and the moving direction of each slider 9L with a needle | hook 9R are orthogonal, it does not need to be orthogonal.
[0036]
Next, an operation of attaching the corner shelves having the above configuration to the wall surfaces 4L and 4R of the triangular corner portion of the room will be described.
[0037]
First, the innermost shelf member 1A having the smallest width is arranged and held so that the left and right mounting surfaces 5L and 5R are in contact with the corner wall surfaces 4L and 4R, and then the surface on which the extrusion cam 16 is formed. The operation plate 7 is inserted into the operation plate guide hole 8 on the front surface 6a of the shelf member 1 and pushed. As shown in FIGS. 12 and 13, the pushing force causes the sliders 9L and 9R with needles to move outward in the left-right direction, and the respective needles 31 are inserted into the corner wall surfaces 4L and 4R, so that the shelf member 1A is Attached to the corner wall surfaces 4L and 4R, a part of the corner shelf (the innermost part) is formed. For the normal corner wall surfaces 4L and 4R, the pushing force of the operation plate 7 is increased by the boosting action of the pushing cam 16 (the smaller the angle formed between the cam surfaces 18 and 18 is, the larger the boosting magnification is). Therefore, the above operation can be performed only by the pushing force of a person. When the corner wall surfaces 4L and 4R are made of a hard material, the mounting operation may be performed by driving the operation plate 7 with a wooden hammer or the like.
[0038]
Next, the operation plate 7 is extracted from the shelf member 1A, and the connecting convex portions 11L and 11R of the shelf member 1B on the front side of the shelf member 1A are fitted into the connecting concave portions 12L and 12R of the shelf member 1A and attached to the left and right sides thereof. It arrange | positions and hold | maintains so that the surfaces 5L and 5R may contact the corner wall surfaces 4L and 4R. At this time, since the vertical movement is restricted by the fitting of the connecting convex portions 11L and 11R and the connecting concave portions 12L and 12R, the mounting operation is facilitated. Then, the extracted operation plate 7 is inserted and pushed into the operation plate guide hole 8 from the front surface 6a of the shelf member 1B. The operation plate 7 is extracted, the shelf member 1 is connected and held, and the operation work by inserting and pushing the operation plate 7 is sequentially performed on the front shelf member 1, and the plurality of shelf members 1A to 1C are moved from the corner to the front. And continuously attached to the corner wall surfaces 4L and 4R. In this embodiment, the shelf members 1A to 1C are connected by fitting the connecting protrusions 11L and 11R and the connecting recesses 12L and 12R to form the shelf main body having the same surface. The shelf members 1A to 1C may be attached at intervals to form a corner shelf having a trapezoidal shape in a plan view and a bowl shape.
[0039]
When the corner shelf is formed and attached as described above, the operation plate 7 inserted into the foremost shelf member 1C is accommodated as it is, and its base end surface 27 is flush with the front surface 6a of the shelf member 1C. It is possible to prevent the appearance and the appearance from deteriorating, and to make it ready for use when the corner shelf is removed.
[0040]
Next, an operation for removing the corner shelf formed as described above from the corner wall surfaces 4L and 4R will be described.
