Description

【０００１】
【発明の属する技術分野】
本発明は一般家庭用の冷蔵庫に係り、特に庫内に収容する食品の大きさに合わせて棚の位置を可変できる冷蔵庫に関するものである。
【０００２】
【従来の技術】
従来のこの種の冷蔵庫は、例えば、特開平７−１２４５２号公報に開示されているように、庫内の側壁に設けた複数段の溝に棚を水平方向からに挿入するようになっているものが多い。これによると、溝から棚を引き出し、他の段の溝に戻すことにより、庫内に収容する食品の大きさに合わせて棚の位置を変更できる。
【０００３】
【発明が解決しようとする課題】
しかしながら、このような冷蔵庫の構成では、一旦棚を引き出してからでないと、その高さを変更できないため、非常に手間が掛かる作業を余儀なくされ、使い勝手が悪かった。しかも、冷蔵庫の扉が開閉式であり、扉の背面側に収納ポケットがある場合、前記収納ポケットや取付扉に棚が当たり、扉を９０°以上開かないと、棚を抜き取ることができない。従って、冷蔵庫を壁に密着して設置した場合において、扉が壁側にしか開くことができないようなときは、棚を取り出すことができなくなるという問題があった。
【０００４】
本発明は上記従来の問題に鑑みてなされたものであり、棚を手前に引き出す距離を短くして容易に棚の高さを変更できる使い勝手のよい冷蔵庫を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するため本発明による冷蔵庫は、庫内左右の側壁に棚を摺動可能に支持するとともに上下方向に並設される第１、第２支持部を設け、前記棚を手前に引くことにより、上段の第１支持部と前記棚との間に設けた凹凸遊嵌構造を利用して前記棚の高さを変更できるようにして、前記棚を手前に引いて下降させたとき、前記棚が下段の第２支持部に保持されるようになっていることを特徴とする。
【０００６】
これによると、棚を庫内から抜き取ることなく、所定の距離だけ手前へ引き出すだけでその高さを変更できる。また、前記棚を手前に引いて下降させたとき、前記棚が下段の第２支持部に保持されるようにすることで、棚は前記下段の第２支持部より下方には落下しないため、棚を確実に異なる段に下降させることができる。
【０００７】
また、本発明による冷蔵庫は、庫内左右の側壁に設けられ棚を摺動可能に支持するとともに上下方向に並設される第１、第２支持部と、前記棚の側縁部に切欠き形成された切欠き部とを有し、上段の第１支持部と前記切欠き部とから成る凹凸遊嵌構造を形成し、前記棚を手前に引くことにより、前記切欠き部が前記支持部を上下方向で通過可能とし、前記棚の高さを変更できるようにして、前記棚を手前に引いて下降させたとき、前記棚が下段の第２支持部に保持されるようになっていることを特徴とする。
【０００８】
これによると、棚を庫内から抜き取ることなく、所定の距離だけ手前へ引き出すだけでその高さを変更できる。また、前記棚を手前に引いて下降させたとき、前記棚が下段の第２支持部に保持されるようにすることで、棚は前記下段の第２支持部より下方には落下しないため、棚を確実に異なる段に下降させることができる。
【０００９】
この場合、前記凹凸遊嵌構造を上下方向で通過する構造を左右に各々複数設けると、前記棚の高さを変更するために、前記棚の上記引き出しの距離を短縮される
【００１０】
そして、前記凹凸遊嵌構造を上下方向で通過する構造を前記側壁の左右に上下方向で複数設けると、棚を庫内から抜き取ることなく、所定の距離だけ手前へ引き出すだけでその高さを複数段階に変更できる。
【００１１】
また、本発明による冷蔵庫は、庫内左右の側壁に沿って摺動可能な棚の側縁部に凹部を挟んで設けた複数の凸部と、前記側壁に略対向して設けられるとともに前記棚が載置され前記凹部が上下方向で通過可能な複数の支持部とを有し、前記側壁に沿って前記棚を手前に引くことにより、前記複数の凹部の一つ一つを前記複数の支持部の対応するものに嵌通させて前記棚の載置位置を上下に変更できるようにして、前記棚を手前に引いて下段の支持部に下降させたとき、前記下段の支持部の少なくとも一つに前記棚が保持されるようになっていることを特徴とする。
【００１２】
これによると、棚を庫内から抜き取ることなく、所定の距離だけ手前へ引き出すだけでその高さを変更できる。また、棚を手前に引いて下段の支持部に下降させたとき、前記下段の支持部の少なくとも一つに前記棚が保持されるようにすることで、棚は前記下段の支持部より下方には落下しないため、棚を確実に下の段に下降させることができる。
【００１３】
また、本発明による冷蔵庫は、庫内左右の側壁に棚を摺動可能に支持する支持部を高さ方向に複数段設け、前記棚を手前に引くことにより、前記支持部と前記棚との間に設けた凹凸遊嵌構造を利用して前記棚の高さを変更できるようにして、前記凹凸遊嵌構造は、前記棚の側縁部に設けた凸部と、前記支持部に設けられる凹部とからなり、前記棚を手前に引いた際に前記凸部が前記凹部に遊嵌して、前記棚を上下方向に移動可能にし、同一高さにある左右の前記支持部の前記凹部を、前記棚の凸部にそれぞれ対応させて、各々の段で、前後方向に異なる位置に設け、前記棚を手前に引いて下段の支持部に下降させたとき、前記下段の支持部に前記棚が保持されるようになっていることを特徴とする。
【００１４】
ところで、前記棚の前後方向の移動を規制するストッパー機構を前記支持部と前記棚との間に設けると、棚の前後方向の位置ズレが防止されて安定する。
【００１５】
そのようなストッパー機構は、前記支持部の前縁部に係止され前記棚の奥方への移動を阻止するストッパー前と、その支持部の後縁部に係止され前記棚の手前側への移動を阻止するストッパー後とを前記棚の左右の側縁部に設けることで実現できる。
【００１６】
そして、前記棚の前縁部を上方に持ち上げることにより、前記ストッパー前及び前記ストッパー後による上記係止が解除されるようにすると、ロックを解除して棚を手前へ引き出す操作が容易になる。
【００１７】
更に、前記棚の高さを変更するために上記棚を手前に引く距離以上の奥行きを有する空間を、前記庫内の開口側に設けると、扉を完全に開き切らなくても、前記空間を利用して棚の高さの変更が行える。この場合、扉の背面側に設けた扉ポケットが前記空間に収納できるようにすることで、扉を閉じたとき、扉ポケットが棚の前縁部に衝突する恐れがなくなる。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照して説明する。図１は、本発明に係る冷蔵庫の斜視図である。図２（I）〜（IV）は、冷蔵庫の庫内の棚取付部周辺を正面から見た拡大図、図３は棚が上段レール前、上段レール後に取り付けられている図、図４は、図３の棚を前方に引き、前記上段の各々のレールから下段レール前、下段レール後側へ移動させるときの図、図５は、棚が前記下段の各々のレールに取り付けられている図で、図６は本発明の他の実施例の冷蔵庫の要部正面図で、図７は本発明に係る冷蔵庫に使用される棚の上面図である。
【００１９】
図１において、１は冷蔵庫の本体で、内箱２と外箱３との間に断熱材４を充填して冷蔵庫の本体１が形成されている。５は前後方向にスライド可能に取り付けた棚である。尚、この図において、庫内の開口側を開閉する扉を省略している。
【００２０】
まず、庫内の左右の側壁の構成について図面を参照して説明する。図２（I）は、図１の矢印Ａの方向から見た正面図であり、冷蔵庫の庫内左側の側壁周辺を拡大して示している。この図のように、内箱２の側壁の前方には、上面が略水平の平面にて、下面は側壁に近づくほど厚みが増すような傾斜を有し、先端部分が丸みを帯びた形状にされた上段レール前６ａ及び下段レール前７ａが奥行き方向に延びて設けられている。そして、庫内右側の側壁には、相対向して同様の高さに前記上段レール前６ａ及び下段レール前７ａを左右方向で反転した形状の前記上段レール前（図示せず）及び下段レール前（図示せず）が設けられている。尚、前記形状は真空成形にて内箱２と一体に形成するのに有効である。
【００２１】
更に詳細には、これら上段レール前６ａ及び下段レール前７ａは、上段レール前６ａが上方に、下段レール前７ａが下方になるように、高さ方向で所定の間隔を開けてレール台１２上に突設されている。そして、上段レール前６ａ，下段レール前７ａ及びレール台１２は、ともに内箱２と一体に形成されている。尚、このレール台１２を介して内箱２の側壁に、上段レール前６ａ及び下段レール前７ａをレール台１２と一体に形成してネジ等で取り付けるようにしてもよい。また、図３に示すように、これら上段レール前６ａ及び下段レール前７ａを上方から見ると、両者は略同一形状の略台形をしており、水平方向の前後左右の方向においては互いに同様の位置に設けられている。従って、上方から見ると両者は重なった状態になっている。
【００２２】
内箱２の側壁の後方の相対向する位置には、正面断面の形状が上記の上段レール前６ａ、下段レール前７ａと同様の形状になるように形成された上段レール後６ｂ、下段レール後７ｂが前記レール台１２とともに設けられている。尚、上段レール前６ａと上段レール後６ｂの上面の高さ、下段レール前７ａと下段レール後７ｂの上面の高さは、各々ほぼ同じ高さとなっている。従って、相対向する上段レール前６ａ及び上段レール後６ｂの上面の平坦部、相対向する下段レール前７ａ及び下段レール後７ｂの上面の平坦部は、図１の如く棚５を載置できる略水平な平面（係止部）を形成している。尚、前記各々のレールの棚５の載置部は、凹凸面があってもよく、棚５を支えることができればよく、また、左右方向の庫内中央に向かう溝状の凹部を設けると、冷気流や各々のレール上に溜まった水分を下方に流す役目にもなる。
【００２３】
また、図３（ａ）は、後述する棚５を上方から見た図、図３（ｂ）は後述する棚５を下方から見た図である。図３（ａ）に示すように、上段レール後６ｂ及び下段レール後７ｂを上方から見ると、その後縁部は内箱２の奥方の面取りされたコーナ部２ａにつながっており、一方、その前縁部は後方に進むにつれて幅広となるように傾斜した形状となっている。また、下段レール後７ｂの前縁部は、上段レール後６ｂのそれより手前側に延長されている。尚、上段レール前６ａの後縁部と上段レール後６ｂの前縁部とに挟まれた部分は、上方から見ると略台形をしており、後述する棚５の後凸部５ｂが上下方向で移動可能で遊嵌可能な第２凹部６ｃとなっている。そして、前記の傾斜は、真空成形にて内箱２と一体に成形するのに有効である。
【００２４】
次に、棚５の左右の側縁部周辺の構成について図２〜図５及び図７を参照して説明する。尚、図４（ａ），図５（ａ）及び図７はいずれも棚５を上方から見た図、図４（ｂ）及び図５（ｂ）はいずれも棚５を下方から見た図である。棚５の側縁部の前方及び後方は、略台形に切欠き形成された第１凹部５ｃを挟んで前凸部５ａ及び後凸部５ｂとなっている。第１凹部５ｃの形状は、略台形をした上段レール前６ａが遊嵌可能な略台形に形成されており、後凸部５ｂの形状は、上段レール前６ａと上段レール後６ｂとの間に形成される第２凹部６ｃに遊嵌可能な略台形に形成されている。
【００２５】
従って、図４の状態のように、所定の距離だけ棚５を引き出したとき、上段レール前６ａと第１凹部５ｃが前方で遊嵌するとともに、後凸部５ｂと第２凹部６ｃが後方で遊嵌するようなっている。そして、この状態では棚５を上下に移動させることができる。つまり、後凸部５ｂが第２凹部６ｃを通り抜け、上段レール前６ａが第１凹部５ｃを通り抜けることにより、棚５は上段又は下段のレール面上へ載せ変えることが可能となる。尚、棚５が上段レールから下段レールに降りたとき、棚５の後凸部５ｂの後縁部が下段レール後７ｂの前縁部に掛かり、下段レール７ｂより下には棚５は下がらないようになっており、安全性を確保するストッパーとしての役割を担っている。
【００２６】
図３（ｂ），図５（ｂ）において、棚５の下面にはストッパー前８、ストッパー後９及び上下ストッパー１０が設けられている。ストッパー前８は、棚５が取付位置に載置された状態で上段レール前６ａ又は下段レール前７ａの前縁部に係止されるようになっている。一方、ストッパー後９は、棚５が取付位置に載置された状態で上段レール前６ａ又は下段レール前７ａの後縁部に係止されるようになっている。
【００２７】
上下ストッパー１０は、棚５の側縁部側に緩やかなカーブを持って棚５の下方に突設されており（図２（I）参照）、棚５が前記各々のレール面上に載置された状態で上段レール前６ａ又は下段レール前７ａの下側に潜り込んで上下方向の棚５の極度のがたつきを防止するとともに、棚５の高さを変更するとき、棚５の前後方向の摺動を案内するガイドの役割を果たす（図２（III）参照）。
【００２８】
そのため、前記ストッパー前８やストッパー後９で上段レール前，後６ａ，６ｂ又は下段レール前，後７ａ，７ｂ上の取付位置に棚５が載置されているときは、前後方向の棚５の位置ズレが防止される。しかも、従来あった背面側のストッパーを省略でき、それによって庫内の背壁がデザイン面で良好になるとともに、背壁の少なくとも一部に熱伝導部材を設けることができ、背壁の後方に形成される冷気通路を流通する冷気の冷熱を前記熱伝導部材の全面から効率よく庫内に放出できるようになる。
【００２９】
尚、前記で、ストッパー前８を省略し、棚５の取付位置後部の少なくとも一部が庫内の対応する壁面（例えば、背壁）に当たるようにしておくと、これもまた、前後方向のストッパーの役割をし、上記と同様の作用・効果が得られ、更にはストッパー前，後８，９のいずれか一方のみであっても、一方向のストッパーとなり、上記と類似の作用・効果は得られる。
【００３０】
尚、図３〜図５における１１は、開閉式の扉（図示せず）を閉じたとき、扉の背面側に設けられた扉ポケット（図示せず）が棚５と間隔を開けて収納できる空間である。従って、棚５を前記各々のレール面上に載置した状態で扉を閉じても、扉ポケットが棚５の前縁部に当接して破損する恐れがない。しかも、空間１１の奥行き方向の長さは、棚５を前方に引き出したとき、後凸部５ｂが第２凹部６ｃを、上段レール前６ａが第１凹部５ｃを通る位置となるための引き出し距離に近い値か、それ以上の値に設定されている。そのため、扉を完全に開き切らなくても、扉を開いて扉ポケットや扉の突き出し部の大部分が棚５の前縁部から離れた段階で、棚５を所定距離だけ引き出してその高さを変更できる使い勝手のよい冷蔵庫を提供できる。
【００３１】
次に、以上のように構成された冷蔵庫の棚５の高さを変更する手順の一例について図２〜図５を参照して説明する。尚、図２（I）は棚５を上段レール前，後６ａ，６ｂ上の取付位置に載置した図、図２（II）は図２（I）で棚５の前方を浮かし、ストッパー前８、ストッパー後９を上段レール前６ａから脱した図、図２（III）は図４で説明したように、後凸部５ｂが第２凹部６ｃを、上段レール前６ａが第１凹部５ｃを通り、下段レール後７ｂ上に棚５が下降し、棚５の前方を浮かし気味に後方へ押しやり、ストッパー前８やストッパー後９が下段レール前７ａの上面に、上下ストッパー１０が下段レール前７ａの下方に位置した図、図２（IV）は棚５を下段レール前，後７ａ，７ｂ上の取付位置に載置した図である。
【００３２】
図２（I）及び図３に示すように、リブ状に形成されたストッパー前８及びストッパー後９により上段レール前６ａは前後方向の移動が阻止されており、これにより前後方向の棚５の位置ズレが防止される。尚、図３（ｂ）は図３（ａ）を下方から見た図であり、上段レール前６ａと下段レール前７ａとは前後方向で同じ位置に存在している。
【００３３】
この状態から例えば、棚５の手前を持ってわずかに持ち上げることで、ストッパー前，後８，９と上段レール前６ａとの係止を解除でき、図２（II）に示すように、棚５を側縁部の長さの１／３程度手前（図１中のＦの方向）へ引き出すことで、図４の如く、上段レール前６ａと第１凹部５ｃとを遊嵌させるとともに、後凸部５ｂと第２凹部６ｃとを遊嵌させることができる。
【００３４】
これにより、棚５は上段レール前、後６ａ，６ｂによる支持がなくなるため、棚５を手で保持していた力を弱めることで、棚５を下段レール前，後７ａ，７ｂ側に下降させることができる。下段レール後７ｂは、上段レール後６ｂより前縁部が前方に延長されているため、水平状態に保って下降させた棚５の後凸部５ｂは、下段レール後７ｂにより保持され、その後図２（III）に示す状態となる。
【００３５】
そして、上下ストッパー１０をガイドとして棚５を奥方（図１中のＤの方向）に１／３程度押し込むことで、図２（IV）及び図５に示すように、ストッパー前８及びストッパー後９が、それぞれ下段レール前７ａの前縁部及び後縁部に係止されるように落ち込んで、棚５の前後方向の位置ズレが防止されるようになっている。尚、図５（ｂ）は図５（ａ）を下方から見た図である。
【００３６】
これにより、棚５を下段レール前、後７ａ，７ｂ上に下降させて、その高さを容易に変更できる。また、上記と逆の手順で、棚５を上段レール前，後６ａ，６ｂ上に上昇させることができる。
【００３７】
従って、本発明によると、従来のように棚５を完全に抜き取る必要がなく、わずか１／３程度引き出すだけで容易に棚５の高さを変更できる。しかも、庫内開口側に扉ポケット収納用の空間１１を設けているため、扉を完全に開き切らなくても、棚５の上記引き出しが行え、使い勝手の向上が図られる。尚、空間１１の奥行き方向の長さは、少なくとも棚５の上記引き出しの距離より長い寸法に選ばれている。
【００３８】
そのため、扉を開き切らずに棚５を上下に移し変えることができる。尚、扉を略９０°に開き、扉ポケットや扉の一部等が庫内から出て棚５の先端から離れ、棚５を上下に移動させるときに、引き出した棚５の前縁部に前記扉ポケットや扉の一部等が当接しない位置関係となる場合は、空間１１の奥行き方向の長さは上記引き出し距離より短くてもよい。
【００３９】
更に本発明の構成を応用することで、上段、中段、下段と三段階に棚５の高さを変更できようにできる。即ち、後方の各々レールの前縁部を上段、中段、下段の順に前方に延長させておき、それに対応する長さの分だけ、前方の各々のレールの後縁部を上段、中段、下段の順に前方に退避させ、前記後凸部５ｂと前記第２凹部６ｃとのような遊嵌関係をもたすようにする。
【００４０】
これにより、棚５が上段から中段へ下降したときは、中段の後方のレールに棚５は保持され、中段から下段へ下降したときは、下段の後方のレールに棚５は保持されるため、棚５の前縁部のみを手で保持して所定の距離だけ手前へ引き出して押し込むという簡単な操作で、上段から中段へ、中段から下段へと棚５を移動できる。尚、三段階のみならず、もっと段階多く設けた複数列のレールに対し、レールの強度が許す範囲で、このような構成を応用することで、同様の操作で複数段階に棚５を下方へ移動させることができる。
【００４１】
また、本発明の変形として、図６に示すように、下段レール前，後７ａ，７ｂからなる下段レール７と、上段レール前，後６ａ，６ｂからなる複数列の上段レール６₁、６₂・・・６_n-1（ｎは２以上の自然数）とを等間隔で内箱２の左右側壁に設けることで、ｎ段階に棚５の高さをきめ細かに変更できる。更に、下段レール７ｂの下にこの下段レール７及び上段レール６の組を複数設けることで、複数の棚５の高さをｎ段階にきめ細かに変更できる。
【００４２】
更には、レールやレール側に形成される凹部の個数及び棚の側縁部の凹部や凸部の個数は上記の実施形態に限られず、単数であっても２つ以上であってもよい。要は、棚を所定距離引き出したとき、上記のようなレール側の凹部と棚の凸部との遊嵌関係の個数、並びにレールと棚の凹部との遊嵌関係の個数が一致しておればよい。このような棚と庫内左右の側壁との間の遊嵌機構を利用すれば、自由自在に棚の高さを変更できる。
【００４３】
尚、レールと棚の凸部が単数である場合は、レールと棚の凸部で棚を側方で係止させるとともに、内箱の背壁から突出させた突出部により棚を後方で支持又は挟持させておくことで、棚の上下方向の極度のがたつきを防止できる。
【００４４】
特に、そのような遊嵌関係の個数を増やしたときは、上記のように棚と庫内左右の側壁との間の遊嵌機構を利用して棚の高さを変更するための棚の引き出しの距離が棚の側縁部の長さの１／３程度より更に短くて済むようになる。従って、扉の開く角度が小さくても、庫内開口側の空間をうまく利用することで、短い引き出し距離で棚の高さを自由に変更できる。更には、後凸部５ｂ、上段レール後６ｂの前縁部を後方に移し、それに応じて前凸部５ａの後端部を前方に移しても、棚５の上記引き出しの距離を短くできる。ただし、レールの強度等との兼ね合いも勘案して、適切な棚の引き出し距離になるよう、上記の遊嵌関係の個数を設定することが必要である。
【００４５】
尚、上記では、後凸部５ｂ及び第２凹部６ｃ、上段レール前６ａ及び第１凹部５ｃが互いに対応した略台形にしてあるため、各々の左右方向の隙間を少し設け、棚５の上下に通過のとき、棚５を左右に揺らすと、各々の傾斜面の隙間関係は広くなり、更に通過しやすくなる。尚、この傾斜面は前後の片側であっても類似の効果は得られる。
【００４６】
また、上記では、上段レール前６ａ、下段レール前７ａは上方から見ると略同一形状であったが、上下２段のレールで棚５を上段・下段に位置させる場合は、下段レール前７ａの形状は同一である必要はなく、棚５を支持して耐えうる強度があれば、異なる形状であっても上記と同様の効果は得られる。
【００４７】
また、有効な遊嵌関係が得られる構造であれば、レール、レール側の凹部、棚の凸部及び凹部の形状は、上記の実施形態のような略台形に限定されないことはもちろんである。
【００４８】
そして、前記は凹凸遊嵌構造の一例であるが、例えば、前記各々のレール前やレール後を一つのものにつなぎ、レバーを引くことにより、棚の凸部に対応する前記レールに凹部が生じるような構造にしておくと、棚を前後に移動することなく遊嵌構造にて、棚を上下に移動できるようになる。
【００４９】
また、前記各々のレールが左側に１個づつ備わっている場合であっても、棚により上下二段に分けていた貯蔵室と、前記棚を下げることにより、背の高い貯蔵物が収納できるようになり、チルド室等の収納方式に使い勝手のよい効果が得られる。
【００５０】
そして、前記各々のレールは冷蔵庫の庫内の側壁から突設して設けられているが、逆に凹設して設けて、それに応じた棚形状にしても、上記と同様の効果は得られる。
【００５１】
更に、前記各々の凹部等により生じる開口部は、冷気が前記開口部を通り上方から下方へ流れるのに役立ち、庫内冷気の循環に有効で、庫内をいつも略均一に冷却させる効果を生じる。
【００５２】
尚、前記図２〜図６は、本発明の冷蔵庫の左側についてのものであるが、右側に関しては各図を左右反転した形状となる。
【００５３】
【発明の効果】
以上説明したように本発明によると、棚と庫内側壁との間に設けた凹凸遊嵌機構によって棚を所定距離だけ手前へ引き出すだけで、容易に棚の高さを変更できる冷蔵庫を提供できる。また、庫内開口側に扉ポケット収納用の空間を形成することにより、扉を完全に開き切らなくても、棚の上記所定距離の引き出しが行え、使い勝手の向上が図られる。

BACKGROUND OF THE INVENTION
The present invention relates to a general household refrigerator, and more particularly to a refrigerator capable of changing the position of a shelf in accordance with the size of food stored in a warehouse.
[0002]
[Prior art]
A conventional refrigerator of this type is configured to insert a shelf from a horizontal direction into a plurality of grooves provided on a side wall in a cabinet, as disclosed in, for example, Japanese Patent Application Laid-Open No. 7-12452. There are many things. According to this, the position of a shelf can be changed according to the magnitude | size of the foodstuff accommodated in a warehouse by pulling out a shelf from a groove | channel and returning it to the groove | channel of another step.
[0003]
[Problems to be solved by the invention]
However, in such a refrigerator configuration, the height can be changed only after the shelves are pulled out, which necessitates laborious work and is inconvenient. In addition, when the refrigerator door is openable and the storage pocket is on the back side of the door, the shelf hits the storage pocket or the mounting door, and the shelf cannot be removed unless the door is opened 90 ° or more. Therefore, when the refrigerator is installed in close contact with the wall, there is a problem that the shelf cannot be taken out when the door can be opened only on the wall side.
[0004]
The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an easy-to-use refrigerator that can easily change the height of the shelf by shortening the distance of pulling the shelf forward.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a refrigerator according to the present invention includes first and second support portions that are slidably supported on the left and right side walls of the cabinet and are arranged in parallel in the vertical direction, and the shelf is pulled forward. By making it possible to change the height of the shelf by using the uneven loose fitting structure provided between the first support portion on the upper stage and the shelf, when the shelf is pulled down and lowered, The shelf is held by a lower second support portion.
[0006]
According to this, the height can be changed only by pulling it forward by a predetermined distance without removing the shelf from the interior. Further, when lowered by pulling the shelf forward, because the shelf by to be held in the second support portion of the lower shelf is not fall below the second support portion of the lower, The shelf can be reliably lowered to a different stage.
[0007]
In addition, the refrigerator according to the present invention is provided on the left and right side walls of the cabinet and supports the shelf slidably, and the first and second support portions arranged side by side in the vertical direction, and a notch in the side edge of the shelf. And forming a concave-convex loosely-fitting structure composed of an upper first support portion and the notch portion, and pulling the shelf forward, so that the notch portion is the support portion. Can be passed in the vertical direction, the height of the shelf can be changed, and when the shelf is pulled down and lowered, the shelf is held by the lower second support portion. It is characterized by that.
[0008]
According to this, the height can be changed only by pulling it forward by a predetermined distance without removing the shelf from the interior. Further, when lowered by pulling the shelf forward, because the shelf by to be held in the second support portion of the lower shelf is not fall below the second support portion of the lower, The shelf can be reliably lowered to a different stage.
[0009]

[0019]
In FIG. 1, reference numeral 1 denotes a refrigerator main body, and a refrigerator main body 1 is formed by filling a heat insulating material 4 between an inner box 2 and an outer box 3. A shelf 5 is slidably mounted in the front-rear direction. In this figure, a door for opening and closing the opening side in the cabinet is omitted.
[0020]
First, the structure of the left and right side walls in the cabinet will be described with reference to the drawings. FIG. 2 (I) is a front view seen from the direction of arrow A in FIG. 1, and shows an enlarged view of the vicinity of the left side wall in the refrigerator. As shown in this figure, the front side of the inner box 2 has a substantially horizontal flat surface, and the lower surface has a slope that increases in thickness as it approaches the side wall, and the tip is rounded. The upper rail front 6a and the lower rail front 7a are provided extending in the depth direction. And the upper rail front (not shown) and the lower rail front of the upper right rail front 6a and the lower rail front 7a are reversed in the left-right direction to the same height on the side wall on the right side in the warehouse. (Not shown) is provided. The shape is effective for forming integrally with the inner box 2 by vacuum forming.
[0021]
More specifically, the upper rail front 6a and the lower rail front 7a are arranged on the rail base 12 with a predetermined interval in the height direction so that the upper rail front 6a is upward and the lower rail front 7a is downward. Projected to The upper rail front 6a, the lower rail front 7a, and the rail base 12 are all formed integrally with the inner box 2. The upper rail front 6a and the lower rail front 7a may be formed integrally with the rail base 12 on the side wall of the inner box 2 via the rail base 12 and attached with screws or the like. Further, as shown in FIG. 3, when the upper rail front 6a and the lower rail front 7a are viewed from above, they are substantially trapezoids having substantially the same shape, and are similar to each other in the horizontal front-rear and left-right directions. In the position. Therefore, when viewed from above, the two are overlapped.
[0022]
At the opposite positions on the rear side of the side wall of the inner box 2, the front cross section is formed so that the front cross-sectional shape is the same as that of the upper rail front 6 a and the lower rail front 7 a, and the lower rail rear 7 b is provided together with the rail base 12. The heights of the upper surfaces of the upper rail front 6a and the upper rail rear 6b, and the lower rail front 7a and the lower rail rear 7b are substantially the same height. Accordingly, the flat portions on the upper surfaces of the upper rail front 6a and the upper rail rear 6b opposite to each other, and the flat portions on the upper surfaces of the lower rail front 7a and the lower rail rear 7b opposite to each other, can be placed as shown in FIG. A horizontal plane (locking portion) is formed. It should be noted that the mounting portion of each rail shelf 5 may have an uneven surface, as long as it can support the shelf 5, and if a groove-like recess toward the center in the left-right direction is provided, It also serves to flow down the cold airflow and the water accumulated on each rail.
[0023]
FIG. 3A is a view of a later-described shelf 5 as viewed from above, and FIG. 3B is a view of a later-described shelf 5 as viewed from below. As shown in FIG. 3 (a), when the upper rail rear 6b and the lower rail rear 7b are viewed from above, the rear edge is connected to the chamfered corner portion 2a at the back of the inner box 2, on the other hand, The edge portion has a shape that is inclined so as to become wider as it advances rearward. Further, the front edge portion of the lower rail rear portion 7b is extended to the near side from that of the upper rail rear portion 6b. The portion sandwiched between the rear edge of the upper rail front 6a and the front edge of the upper rail rear 6b has a substantially trapezoidal shape when viewed from above, and the rear convex portion 5b of the shelf 5 described later is in the vertical direction. It becomes the 2nd recessed part 6c which can move and can be loosely fitted. The inclination is effective for forming integrally with the inner box 2 by vacuum forming.
[0024]
Next, the configuration around the left and right side edges of the shelf 5 will be described with reference to FIGS. 4 (a), 5 (a), and 7 are views of the shelf 5 as viewed from above, and FIGS. 4 (b) and 5 (b) are views of the shelf 5 as viewed from below. It is. The front and rear of the side edge of the shelf 5 are a front convex portion 5a and a rear convex portion 5b with a first concave portion 5c cut out in a substantially trapezoidal shape. The shape of the first concave portion 5c is formed in a substantially trapezoidal shape in which the substantially trapezoidal upper rail front 6a can be loosely fitted, and the shape of the rear convex portion 5b is between the upper rail front 6a and the upper rail rear 6b. It is formed in a substantially trapezoidal shape that can be loosely fitted in the formed second recess 6c.
[0025]
Therefore, as shown in FIG. 4, when the shelf 5 is pulled out by a predetermined distance, the upper rail front 6a and the first concave portion 5c are loosely fitted in the front, and the rear convex portion 5b and the second concave portion 6c are in the rear. It is designed to fit loosely. In this state, the shelf 5 can be moved up and down. That is, the rear projection 5b passes through the second recess 6c, and the upper rail front 6a passes through the first recess 5c, so that the shelf 5 can be mounted on the upper or lower rail surface. When the shelf 5 descends from the upper rail to the lower rail, the rear edge of the rear projection 5b of the shelf 5 is hooked to the front edge of the rear rail 7b, and the shelf 5 does not fall below the lower rail 7b. It plays a role as a stopper to ensure safety.
[0026]
3 (b) and 5 (b), the front of the stopper 8, the rear 9 of the stopper, and the upper and lower stoppers 10 are provided on the lower surface of the shelf 5. The stopper front 8 is locked to the front edge of the upper rail front 6a or the lower rail front 7a in a state where the shelf 5 is placed at the mounting position. On the other hand, the rear 9 of the stopper is locked to the rear edge of the upper rail front 6a or the lower rail front 7a with the shelf 5 placed at the mounting position.
[0027]
The upper and lower stoppers 10 have a gentle curve on the side edge side of the shelf 5 and project downward from the shelf 5 (see FIG. 2 (I)), and the shelf 5 is placed on each rail surface. When the height of the shelf 5 is changed while the height of the shelf 5 is changed while the bottom of the upper rail front 6a or the lower rail front 7a is submerged in this state, It plays the role of a guide for guiding the sliding movement (see FIG. 2 (III)).
[0028]
Therefore, when the shelf 5 is placed at the mounting position on the upper rail front, rear 6a, 6b or the lower rail front, rear 7a, 7b in the front 8 of the stopper or the rear 9 of the stopper, Misalignment is prevented. In addition, the conventional stopper on the back side can be omitted, whereby the back wall in the cabinet can be improved in terms of design, and a heat conducting member can be provided on at least a part of the back wall, behind the back wall. The cold heat of the cold air flowing through the formed cold air passage can be efficiently released from the entire surface of the heat conducting member into the cabinet.
[0029]
In the above description, if the front 8 of the stopper is omitted and at least a part of the rear portion of the mounting position of the shelf 5 is brought into contact with a corresponding wall surface (for example, the back wall) in the cabinet, this is also a front-rear stopper. The function and effect similar to the above can be obtained, and even if only one of the front and rear 8 or 9 is used, it becomes a one-way stopper, and the same function and effect as above can be obtained. It is done.
[0030]
3 to 5, when an openable door (not shown) is closed, a door pocket (not shown) provided on the back side of the door can be stored with a space from the shelf 5. It is space. Therefore, even if the door is closed while the shelf 5 is placed on each rail surface, the door pocket does not come into contact with the front edge of the shelf 5 and is not damaged. In addition, the length of the space 11 in the depth direction is such that when the shelf 5 is pulled forward, the pull-out distance for the rear protrusion 5b to pass through the second recess 6c and the upper rail front 6a to pass through the first recess 5c. It is set to a value close to or higher than. Therefore, even if the door is not completely opened, when the door is opened and most of the door pocket and the protruding portion of the door are separated from the front edge of the shelf 5, the shelf 5 is pulled out by a predetermined distance and the height is increased. An easy-to-use refrigerator that can be changed is provided.
[0031]
Next, an example of a procedure for changing the height of the refrigerator shelf 5 configured as described above will be described with reference to FIGS. 2 (I) is a view in which the shelf 5 is placed at the mounting position on the front rails 6a and 6b in front of the upper rail, and FIG. 2 (II) is the front of the shelf 5 in FIG. 8 and FIG. 2 (III) is a view in which the rear 9 of the stopper is removed from the upper rail front 6a. FIG. 2 (III) is the rear concave portion 5b is the second concave portion 6c, and the upper rail front 6a is the first concave portion 5c. Street, the shelf 5 descends on the rear of the lower rail 7b, and the front of the shelf 5 is lifted and pushed backwards, the front 8 of the stopper and the rear 9 of the stopper are on the upper surface of the lower rail 7a, and the upper and lower stoppers 10 are in front of the lower rail. FIG. 2 (IV) is a view of the shelf 5 placed at the mounting positions on the front and rear 7a, 7b of the lower rail.
[0032]
As shown in FIG. 2 (I) and FIG. 3, the front rail 6a is prevented from moving in the front-rear direction by the front and rear stoppers 8 and 9 formed in a rib shape. Misalignment is prevented. FIG. 3B is a view of FIG. 3A as viewed from below, and the upper rail front 6a and the lower rail front 7a are present at the same position in the front-rear direction.
[0033]
From this state, for example, by holding the front side of the shelf 5 and slightly lifting it, it is possible to release the locking between the front of the stopper, the rear 8, 9 and the upper rail front 6a, as shown in FIG. 2 (II). 4 is pulled out to about 1/3 of the length of the side edge (in the direction of F in FIG. 1), the upper rail front 6a and the first recess 5c are loosely fitted as shown in FIG. The part 5b and the second recess 6c can be loosely fitted.
[0034]
As a result, the shelf 5 is not supported by the front and rear 6a, 6b before the upper rail, so the shelf 5 is lowered to the front, rear 7a, 7b side by weakening the force holding the shelf 5 by hand. be able to. Since the rear edge of the lower rail 7b is extended forward from the rear of the upper rail 6b, the rear convex portion 5b of the shelf 5 lowered while being kept in a horizontal state is held by the lower rail rear 7b. 2 (III).
[0035]
Then, the upper and lower stoppers 10 are used as guides to push the shelf 5 inward (in the direction of D in FIG. 1) about 1/3, so that as shown in FIGS. However, it falls so that it may be latched by the front edge part and rear edge part of the lower-stage rail front 7a, respectively, and the position shift of the shelf 5 in the front-back direction is prevented. FIG. 5B is a view of FIG. 5A viewed from below.
[0036]
Accordingly, the height of the shelf 5 can be easily changed by lowering the shelf 5 in front of the lower rail and on the rear 7a, 7b. Further, the shelf 5 can be raised on the upper rail front and rear 6a, 6b in the reverse procedure to the above.
[0037]
Therefore, according to the present invention, it is not necessary to completely remove the shelf 5 as in the prior art, and the height of the shelf 5 can be easily changed by pulling out only about 1/3. Moreover, since the space 11 for storing the door pocket is provided on the opening side of the interior, the shelf 5 can be pulled out without completely opening the door, and the usability can be improved. The length of the space 11 in the depth direction is selected to be at least longer than the distance of the drawer 5 of the drawer.
[0038]
Therefore, the shelf 5 can be moved up and down without opening the door. When the door is opened at about 90 °, the door pocket or a part of the door leaves the inside of the cabinet, moves away from the tip of the shelf 5, and moves the shelf 5 up and down, the front edge of the shelf 5 is pulled out. When the positional relationship is such that the door pocket or part of the door does not come into contact, the length of the space 11 in the depth direction may be shorter than the pull-out distance.
[0039]
Furthermore, by applying the configuration of the present invention, it is possible to change the height of the shelf 5 in three stages: an upper stage, a middle stage, and a lower stage. That is, the front edge of each rear rail is extended forward in the order of the upper, middle, and lower stages, and the rear edge of each front rail is the upper, middle, and lower stages by the corresponding length. It is made to retract | save to the front in order, and it has a loose fitting relationship like the said rear convex part 5b and the said 2nd recessed part 6c.
[0040]
Thereby, when the shelf 5 is lowered from the upper stage to the middle stage, the shelf 5 is held on the rear rail of the middle stage, and when the shelf 5 is lowered from the middle stage to the lower stage, the shelf 5 is held on the rear rail of the lower stage. The shelf 5 can be moved from the upper level to the middle level and from the middle level to the lower level by a simple operation of holding only the front edge of the shelf 5 by hand and pulling it out to the front by a predetermined distance. By applying such a configuration to the multiple rows of rails provided in more stages, not only in three stages, but within the range that the rail strength allows, the shelf 5 can be moved downward in multiple stages by the same operation. Can be moved.
[0041]
As a modification of the present invention, as shown in FIG. 6, a lower rail 7 consisting of front and rear 7a, 7b and a plurality of upper rails 6 ₁ , 6 ₂ consisting of front and rear 6a, 6b. ... 6 _n-1 (n is a natural number of 2 or more) are provided on the left and right side walls of the inner box 2 at equal intervals, so that the height of the shelf 5 can be finely changed in n stages. Furthermore, by providing a plurality of sets of the lower rail 7 and the upper rail 6 below the lower rail 7b, the height of the plurality of shelves 5 can be finely changed in n stages.
[0042]
Furthermore, the number of recesses formed on the rail or rail side and the number of recesses or projections on the side edge of the shelf are not limited to the above embodiment, and may be singular or two or more. In short, when the shelf is pulled out by a predetermined distance, the number of loose fitting relationships between the rail-side concave portion and the convex portion of the shelf as described above and the number of loose fitting relationships between the rail and the concave portion of the shelf should be the same. That's fine. If such a loose fitting mechanism between the shelf and the left and right side walls is used, the height of the shelf can be freely changed.
[0043]
In addition, when the rail and the convex part of the shelf are singular, the shelf is locked laterally by the convex part of the rail and the shelf, and the shelf is supported rearward by the protruding part protruding from the back wall of the inner box or By holding it, it is possible to prevent extreme rattling in the vertical direction of the shelf.
[0044]
In particular, when the number of such loose fitting relations is increased, the shelf drawer for changing the height of the shelf using the loose fitting mechanism between the shelf and the left and right side walls as described above. Is shorter than about 1/3 of the length of the side edge of the shelf. Therefore, even if the opening angle of the door is small, the height of the shelf can be freely changed with a short pull-out distance by making good use of the space on the opening side in the cabinet. Furthermore, even if the front edge of the rear projection 5b and the upper rail rear 6b is moved rearward and the rear end of the front projection 5a is moved forward accordingly, the distance of the drawer 5 of the shelf 5 can be shortened. However, it is necessary to set the number of the loose fitting relations so as to obtain an appropriate shelf pull-out distance in consideration of the balance with the rail strength and the like.
[0045]
In the above description, since the rear convex portion 5b and the second concave portion 6c, the upper rail front portion 6a and the first concave portion 5c are substantially trapezoidal shapes corresponding to each other, a little gap is provided in the left and right direction, and When the shelf 5 is swung to the left and right during the passage, the relationship between the gaps between the inclined surfaces becomes wider and the passage becomes easier. A similar effect can be obtained even if this inclined surface is on one side of the front and rear.
[0046]
In the above description, the upper rail front 6a and the lower rail front 7a have substantially the same shape when viewed from above. However, when the shelf 5 is positioned in the upper and lower stages with two upper and lower rails, the lower rail front 7a The shapes do not need to be the same, and the same effect as described above can be obtained even if the shapes are different as long as they have strength to support and support the shelf 5.
[0047]
Further, as long as an effective loose-fitting relationship is obtained, the shape of the rail, the rail-side recess, the shelf projection, and the recess is not limited to the substantially trapezoidal shape as in the above embodiment.
[0048]
And, the above is an example of the concave and convex loose fitting structure. For example, by connecting the front and rear of each rail to one and pulling the lever, a concave portion is formed in the rail corresponding to the convex portion of the shelf. With such a structure, the shelf can be moved up and down with a loose fitting structure without moving the shelf back and forth.
[0049]
In addition, even when each rail is provided on the left side, a storage room divided into two upper and lower stages by shelves and a lower store so that tall storage items can be stored. Therefore, an easy-to-use effect can be obtained in a storage system such as a chilled room.
[0050]
And although each said rail protrudes and is provided from the side wall in the refrigerator compartment, the same effect as the above is acquired even if it makes it concavely provided and makes it the shelf shape according to it. .
[0051]
Further, the opening formed by each of the recesses or the like serves to help cool air flow from the upper side to the lower side through the opening, is effective for circulation of the cool air inside the cabinet, and has an effect of cooling the inside of the cabinet almost uniformly. .
[0052]
2 to 6 are for the left side of the refrigerator according to the present invention, but the right side has a shape obtained by horizontally inverting each figure.
[0053]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a refrigerator that can easily change the height of a shelf simply by pulling the shelf forward by a predetermined distance by the uneven loose fitting mechanism provided between the shelf and the inner wall of the cabinet. . Moreover, by forming a space for storing the door pocket on the opening side in the cabinet, the shelf can be pulled out by the predetermined distance without completely opening the door, and the usability is improved.
