【発明の属する技術分野】
本発明は、冷蔵庫等の貯蔵庫内に引き出し自在に設けた容器に収納した物品の取り出しに係る物品収納装置に関する。
【０００２】
【従来の技術】
冷蔵庫の野菜室に前方へ引き出し自在に野菜容器を設け、この野菜容器の前部に、幅方向にわたってペットボトルを収容するための背高用収容部を設けたものがある（例えば、特許文献１参照）。このペットボトルを収容するための背高用収容部は、底部が他の部分に比べて一段低くなっていて、比較的高さが高い貯蔵物であるペットボトルを収容することができるようになっている。
【０００３】
【特許文献１】
特開平１１−３０４３５４号公報（第１〜５頁、図１〜４）。
【０００４】
【発明が解決しようとする課題】
特許文献１におけるペットボトルを収容するための背高用収容部は、底部が他の部分に比べて一段低くなっており、野菜容器を引き出したときにもそのペットボトルの収容状態に変動がないため、比較的背が高いペットボトルは取り出し易いが、背が低いボトルやその他の物は背高用収容部の底に手を差し入れなければ取り出し難いものとなる。
【０００５】
本発明はこのような点に鑑み、冷蔵庫等の貯蔵庫内に引き出し自在に設けた容器に収納した物品が、背が低い場合にもその取り出しが容易になる物品収納装置を提供するものである。また背が高い物品でも、容器の引き出しの支障にならない構成の物品収納装置を提供するものである。
【０００６】
【課題を解決するための手段】
本発明の貯蔵庫の物品収納装置は、前面開口の貯蔵室内に上面開口の容器が前方へ引き出し自在に収納され、前記容器内に設けた物品載置用底板が前記容器の引き出しに伴って上昇することを特徴とする。
【０００７】
これによって、容器に収納した物品が、背が低い場合にもその取り出しが容易になる物品収納装置を提供できる。
【０００８】
また、本発明の貯蔵庫の物品収納装置は、前面開口の貯蔵室内に上面開口の容器が前方へ引き出し自在に収納され、前記容器内の前部には背高物品収納部が設けられ、前記容器の引き出し途中に前記背高物品収納部の物品載置用底板を最大上昇位置まで上昇させ前記容器の更なる引き出しに伴って前記物品載置用底板を下降する底板作動機構を設けたことを特徴とする。
【０００９】
これによって、容器を途中まで引き出すことにより背高物品収納部に収納した物品が上昇するため、その背高物品収納部に収納した物品の背が低い場合にもその取り出しが容易になる。そして、容器を大きく引き出した状態では、物品載置用底板が下降して背高物品収納部に収納した物品が下降するため、容器の奥に収納した物品の取り出しが容易となる。
【００１０】
また、本発明の貯蔵庫の物品収納装置は、前面開口の貯蔵室内に上面開口の容器が前方へ引き出し自在に収納され、前記容器内の前部には物品載置用底板を備えた背高物品収納部が設けられ、前記容器の底壁には中間部が回動可能に支持された作動部材が設けられ、前記作動部材の一方の端側は前記物品載置用底板に連結され他方の端側には前記貯蔵室の底壁に設けたガイド溝を倣うように嵌め合い部を備え、前記容器の引き出しに伴う前記作動部材の回動によって前記物品載置用底板が上昇することを特徴とする。そして、前記ガイド溝は、前記容器の引き出しに伴う前記作動部材の回動によって前記物品載置用底板が上昇する湾曲形状をなすことを特徴とする。
【００１１】
このため、容器に収納した物品が、背が低い場合にもその取り出しが容易になる物品収納装置を提供できる。そして、作動部材はガイド溝に沿って回動することによって物品載置用底板が上下動するため、容器の引き出し及び収納の抵抗が少なく安定した動作が得られる構成となる。
【００１２】
また、本発明の前記ガイド溝は、前記容器の引き出し途中に前記物品載置用底板が最大上昇位置まで上昇し前記容器の更なる引き出しに伴って前記物品載置用底板が下降するよう前記作動部材が往復回動する湾曲形状をなすことを特徴とする。
【００１３】
これによって、容器を途中まで引き出すことにより背高物品収納部に収納した物品が上昇するため、その背高物品収納部に収納した物品の背が低い場合にもその取り出しが容易になる。そして、容器を大きく引き出した状態では、物品載置用底板が下降して背高物品収納部に収納した物品が下降するため、容器の奥に収納した物品の取り出しが容易となる。そして、ガイド溝の湾曲頂上の位置が前後中央か或いは前方寄りか後方よりかによって、物品載置用底板の最大上昇位置を決めることができるため、容器の形状や貯蔵室の大きさなどによって適正な位置に物品載置用底板の最大上昇位置を定めることが容易となる。
【００１４】
また、本発明の前記ガイド溝は、前記容器の引き出しによって前記物品載置用底板が前記貯蔵室の外領域へ引き出された状態で最大上昇位置となるよう湾曲形状をなすことを特徴とする請求項３または５のいずれかに記載の貯蔵庫の物品収納装置。
【００１５】
これによって、上記効果に加えて、背高物品収納部に収納された物品が上昇しても、貯蔵室の開口上縁に当接しない状態での容器の引き出しを行うようにできる。
【００１６】
【発明の実施の形態】
次に、本発明の貯蔵庫の表示装置について説明する。各図は本発明の実施形態を示しており、図１は本発明の貯蔵庫の一種である冷蔵庫の縦断側面図、図２は本発明の物品収納装置の縦断側面図、図３は本発明の物品収納装置の平面図、図４の（ａ）図は本発明物品収納装置の底板作動機構の説明斜視図、図４の（ｂ）図は本発明物品収納装置の底板作動機構の説明断面図、図５はガイド溝の他の形態を示す図、図６はガイド溝の更に他の形態を示す図、図７は往路と復路を分けたガイド溝の形態を示す図である。
【００１７】
これらの図において、Ｒは貯蔵庫の一つである冷蔵庫であり、前面開口の本体２内を区画して複数の貯蔵室を形成し、これら各貯蔵室の前面は扉で開閉できる構成である。この冷蔵庫において、１は冷蔵庫本体であり、外箱（外壁板）３と内箱（内壁板）２との間に発泡断熱材４を充填した断熱構造である。冷蔵庫本体１内には、貯蔵室として上から冷蔵室５、野菜室６、冷凍室７が区画されて設けられ、冷蔵室５内には複数段に板状棚８が設けられている。冷蔵室５内の底部にはその上方の冷蔵室５と最下段の棚８にて区画された特定低温室９が設けられ、また冷凍室７は上冷凍室１０と下冷凍室１１に区分されている。
【００１８】
冷蔵室５の前面開口は、冷蔵庫本体１の一側部にヒンジ装置にて横方向に回動して開閉される回動式扉１２にて閉塞される。野菜室６の前面開口は、野菜室６内に設けた左右のレール又はローラ装置２８によって前後方向へ引き出し可能に支持した野菜容器１３と共に前方へ引き出される引き出し式扉１４にて閉塞されている。上冷凍室１０と下冷凍室１１は、それぞれ野菜室６と同様に、冷凍室内に設けた左右のレールに対してそれぞれ前後方向へ引き出し可能に支持した容器１５、１６と共に前方へ引き出される引き出し式扉１７、１８にて閉塞されている。
【００１９】
２０は冷凍システムの冷媒の圧縮機、２１は冷凍システムの冷媒の凝縮器、２２は凝縮器２１の熱にて後述の冷却器の除霜水を蒸発させる蒸発皿である。２３、２４は冷凍システムの冷媒の冷却器（蒸発器）であり、２３は冷凍室７用冷却器、２４は冷蔵室５、野菜室６及び特定低温室９用冷却器である。２５は第１冷気循環送風機、２６は第２冷気循環送風機である。冷却器２３で冷却した冷気は送風機２５によって、上冷凍室１０及び下冷凍室１１を経て冷却器２３へ帰還する循環をする。また冷却器２４で冷却した冷気は送風機２６によって、冷蔵室５、特定低温室９及び野菜室６を経て冷却器２４へ帰還する循環をする。このような冷気循環経路は図１に矢印で示す。特定低温室９は、前後方向へ引き出し可能に支持した容器２７が設けられ、０℃前後で食品が凍結しない程度の低温に冷却されるものである。
【００２０】
このような構成において、各室の温度は、冷蔵室５が約３〜４℃、野菜室６が約４〜６℃に保たれ、上冷凍室１０と下冷凍室１１が約−１８℃〜−２０℃である。また、冷蔵室扉１２の内側に設けた貯蔵棚上は５〜８℃である。特定低温室９は、０℃よりも高い約１℃のチルド室であったり、０℃よりも低く食品の凍結温度よりも高い約０〜−１℃の氷温室であったり、また、食品の表面に薄い氷の層が形成される程度の約−４℃の部分凍結室であったりする。このように特定低温室９は、食品を特定の温度領域内で冷却保存するためのものであり、他の室に比して厳しい温度制御が要求される。
【００２１】
本発明の物品収納装置の好ましい実施形態として、野菜容器１３を対象にした実施形態について、以下に説明することとする。本発明に係る容器の一つである野菜容器１３は、上面に開口を有する四角形状の容器を形成し、野菜容器１３内の前部には後部の野菜収納室３３と区画壁３４によって企画された背高物品収納部３２が設けられている。背高物品収納部３２内底部には底板作動機構３０によって上下動する物品載置用底板３１が配置され、背高物品収納部３２は、ペットボトルや縦長の紙パック入り飲料等のように背の高い物品Ｐが、物品載置用底板３１の上に野菜容器１３の横幅方向に一列に並べて収納できる大きさに形成されている。
【００２２】
本発明の貯蔵庫の物品収納装置は、野菜容器１３内に設けた物品載置用底板３１が野菜容器１３の引き出しに伴って上昇するものであり、そのための底板作動機構３０の一つの実施形態として、野菜容器１３の底壁３７には底壁３７の下面に沿って、中間部が軸支持部３６によって回動可能に支持された作動部材３５が前後方向に設けられている。作動部材３５の一方の端側である前端側は、連結部材３８を介して物品載置用底板３１に連結され、他方の端側である後端側には野菜室６の底壁３９に設けたガイド溝４０を倣うように嵌め合い部４１を備える。
【００２３】
連結部材３８は、軸支持部４２によって回動自在に連結した第１連結部材４３と第２連結部材４４で構成し、第１連結部材４３は物品載置用底板３１に軸支持部４９によって回動自在に連結している。また、第２連結部材４４には作動部材３５の前端側に取り付けたガイドピン４５がスライド可能に嵌り合う長孔４６を形成している。作動部材３５と第２連結部材４４との連結は、ガイドピン４５を第２連結部材４４に設け、長孔４６を作動部材３５に形成した構成でもよい。
【００２４】
物品載置用底板３１の左右両側は、それぞれ野菜室６の底壁３９に軸支持部４７、４８によって回動自在に取り付けた可動支持部材４９、５０によって支持され、物品載置用底板３１と可動支持部材４９、５０との連結部は、それぞれ軸支持部５１、５２によって回動自在に連結されている。
【００２５】
ガイド溝４０とそれを倣う嵌め合い部４１は、作動部材３５から下方へ伸びた軸に回転自在に取り付けたローラ５３が、ガイド溝４０に緩く嵌り合っている。後述のように、野菜容器１３の前方への引き出し及び収納の動作に伴ってローラ５３がガイド溝４０に沿って移動するとき、ローラ５３がガイド溝４０の側壁に当接して回転することによって、嵌め合い部４１における接触抵抗を少なくする構成である。
【００２６】
先ず図１乃至図４において、本発明の物品収納装置の動作について、以下に記載する。図３及び図４に示すように、ガイド溝４０は弧状又は弓形に湾曲した湾曲形状をなしている。野菜容器１３が野菜室６内に収納され引き出し式扉１４が閉じた状態では、ローラ５３がガイド溝４０の後端部に位置し、作動部材３５は図３に示す３５Ａの状態である。この状態は初期位置であり、物品載置用底板３１は、下降した状態であり背高物品収納部３２の下部に位置し、物品載置用底板３１に載置されている背の高い物品Ｐは、野菜容器１３から突出しない状態に保たれている。
【００２７】
この状態から扉１４の取っ手を掴んで扉１４を前方へ引くと、レール又はローラ装置２８の支持によって扉１４と共に野菜容器１３が前方へ引き出される。この野菜容器１３の引き出しに伴って、ローラ５３がガイド溝４０の沿って案内され、それによって作動部材３５が軸支持部３６を中心にして回動する。この作動部材３５の回動に伴って、連結部材３８を介して物品載置用底板３１が図４では左方へ、図３では右方へ引っ張られ、物品載置用底板３１は可動支持部材４９、５０の回動を伴って上昇する。
【００２８】
この引き出し動作に伴って、物品載置用底板３１は最大上昇位置へ向けて徐々に上昇する。そして、ローラ４２がガイド溝４０の湾曲形状の頂部分４０Ａに達したとき、物品載置用底板３１は最大上昇位置となる。この最大上昇位置に達した作動部材３５の状態は図３に３５Ｂで示す。物品載置用底板３１が最大上昇位置へ上昇することに伴って背の高い物品Ｐも上昇するが、背の高い物品Ｐが野菜容器１３の引き出し途中に野菜室６の前面開口上縁６Ａに当接しないようにガイド溝４０の形状が形成される。そして、ガイド溝４０は、野菜容器１３の引き出しによって背高物品収納部３２が野菜室６の外領域へ引き出された状態で、即ち物品載置用底板３１が野菜室６の外領域へ引き出された状態で最大上昇位置となるように頂部分４０Ａを定めた湾曲形状をなす。このように最大上昇位置に達した背の高い物品Ｐは、野菜容器１３の上方へ突出するため取り出し易くなる。
【００２９】
物品載置用底板３１が最大上昇位置へ上昇した状態から更に野菜容器１３の引き出しを行うと、ガイド溝４０の湾曲に沿ってローラ５３が移動し、作動部材３５が復帰方向へ回動して物品載置用底板３１が下降し、作動部材３５は図３の３５Ｃの状態に達する。これは、野菜容器１３の引き出し最終状態であり、物品載置用底板３１は、野菜容器１３が野菜室６内に収納され引き出し式扉１４が閉じた状態と同様の位置となる。このため、背の高い物品Ｐは下降し、背高物品収納部３２の奥側の野菜収納室３３に収納した食品の取り出しの邪魔にならないと共に、野菜収納室３３の奥部分に収納した食品を取り出し易くなる。図３に示すＴ１は引き出し式扉１４が閉じた状態から最大上昇位置まで引き出した直線距離を示し、Ｔ２は最大上昇位置から野菜容器１３の引き出しが終了するまでの直線距離を示す。
【００３０】
野菜容器１３の引き出しが終了した状態から引き出し式扉１４を後方へ押して野菜容器１３を野菜室６内へ収納させることにより、ガイド溝４０の湾曲に沿ってローラ５３が移動し、上記の往路動作とは逆動作によって作動部材３５が回動して、物品載置用底板３１は一旦最大上昇位置まで上昇した後、引き出し式扉１４が閉じたとき初期位置へ復帰する。
【００３１】
このように、野菜容器１３を途中まで引き出すことにより背高物品収納部３２に収納した物品Ｐが上昇するため、その背高物品収納部３２に収納した背の高い物品Ｐは勿論のこと、背が低い物品の場合にもその取り出しがし易くなる。そして、野菜容器１３を大きく引き出した状態では、物品載置用底板３１が下降して背高物品収納部３２に収納した物品Ｐが下降するため、野菜容器１３の奥に収納した物品の取り出しが容易となる。
【００３２】
最大上昇位置で背高物品収納部３２に収納した物品Ｐが下降しないような安定を保つためには、野菜容器１３の最終引き出し位置の若干手前で物品載置用底板３１が最大上昇位置となり、野菜容器１３の最終引き出し位置までその状態を保つのが望ましい。このため、ガイド溝４０の終端部に図４に示すように野菜容器１３の引き出し方向に沿った直線部分４０Ｂを形成すればよい。
【００３３】
図５にはガイド溝４０の形態が上記のものとは異なる。即ち、初期位置から最大上昇位置まではガイド溝４０は湾曲形状をなし、最大上昇位置から野菜容器１３の引き出し最終位置まではガイド溝４０は野菜容器１３の引き出し方向に沿った直線状である。５３Ａはローラ５３の初期位置であり、５３Ｂは物品載置用底板３１が最初に到達する最大上昇位置におけるローラ５３の位置であり、５３Ｃは野菜容器１３の引き出し最終位置におけるローラ５３の位置である。この構成によって、物品載置用底板３１は、野菜容器１３の引き出しに伴ってローラ５３が５３Ａの位置から５３Ｂへ移動する間に徐々に上昇し、５３Ｂにおいて最大上昇位置に達し、ローラ５３が５３Ｂから５３Ｃまでの間は最大上昇位置のままである。
【００３４】
この図５の形態では、初期位置から野菜容器１３の引き出しの中間位置までは図１及至図４のものと同様の動作をするが、その後の野菜容器１３の引き出し最終位置までは物品載置用底板３１が最大上昇位置のままであり、背高物品収納部３２に収納した物品Ｐは、野菜容器１３を途中まで引き出した状態では上昇位置を保つため、いつでも取り出し易い効果がある。
【００３５】
野菜容器１３の引き出しが終了した状態から引き出し式扉１４を後方へ押して野菜容器１３を野菜室６内へ収納させることにより、上記の往路Ｙ１方向の動作とは逆動作によって、ガイド溝４０の直線部分に沿ってローラ５３が移動し、その直線部分を過ぎた位置から作動部材３５が回動して、物品載置用底板３１は最大上昇位置から徐々に降下する。そして、引き出し式扉１４が閉じたとき初期位置へ復帰する。Ｙ１は往路を示し、Ｙ２は復路を示す。
【００３６】
図６にはガイド溝４０の他の形態を示す。これにおいて、初期位置から野菜容器１３の引き出し途中までは、ガイド溝４０は野菜容器１３の引き出し方向に沿った直線状であり、その後は野菜容器１３の引き出し最終位置までガイド溝４０は湾曲形状である。５３Ａはローラ５３の初期位置であり、５３Ｂは物品載置用底板３１が上昇を始める位置であり、５３Ｃは野菜容器１３の引き出し最終位置におけるローラ５３の位置である。この構成によって、物品載置用底板３１は、野菜容器１３の引き出しに伴ってローラ５３が５３Ａの位置から５３Ｂへ移動する間は上昇動作がなく、ローラ５３が５３Ｂから５３Ｃまで移動するとき物品載置用底板３１は徐々に上昇し、５３Ｃの位置では最大上昇位置となる。
【００３７】
野菜容器１３の引き出しが終了した状態から引き出し式扉１４を後方へ押して野菜容器１３を野菜室６内へ収納させることにより、上記の往路Ｙ１方向の動作とは逆動作によってガイド溝４０の湾曲に沿ってローラ５３が移動し、作動部材３５が回動して物品載置用底板３１は最大上昇位置から徐々に降下し、引き出し式扉１４が閉じたとき初期位置へ復帰する。Ｙ１は往路を示し、Ｙ２は復路を示す。
【００３８】
この図６の形態では、初期位置から野菜容器１３の引き出しの中間位置までは物品載置用底板３１が上昇しないので、この範囲では背の高い物品Ｐも背高物品収納部３２内で低い位置を保ち、野菜容器１３の引き出し中に野菜室６の前面開口上縁に当接することはない。そして、更に野菜容器１３の引き出しを行うことにより、物品載置用底板３１は徐々に最終位置へ向けて上昇し、野菜容器１３の最終引き出し位置において物品載置用底板３１が最大上昇位置となる。
【００３９】
この最大上昇位置で背高物品収納部３２に収納した物品Ｐが下降しないような安定を保つためには、野菜容器１３の最終引き出し位置の若干手前で物品載置用底板３１が最大上昇位置となり、野菜容器１３の最終引き出し位置までその状態を保つのが望ましい。このため、ガイド溝４０の終端部に図６に点線で示すように、野菜容器１３の引き出し方向に沿った直線部分４０Ｂを形成し、この直線部分４０Ｂにローラ５３が位置したとき（点線５３Ｃの位置）を野菜容器１３の最終引き出し位置とすればよい。
【００４０】
図７にはガイド溝４０の更に他の形態を示す。これにおいて、初期位置から野菜容器１３の引き出し最終位置までの往路Ｙ１の動作は、図１乃至図４に示した場合と同様である。即ち、ガイド溝４０の往路Ｙ１の形態は図１乃至図４に示した場合と同様であるが、野菜容器１３の引き出し方向に沿った直線状の復路Ｙ２を往路Ｙ１に並列状態に別個に形成した点で新しい。ガイド溝４０は往路Ｙ１と復路Ｙ２が両端部で連続して全体として略Ｄ文字形状をなす。そして、ローラ５３は、初期位置５３Ａから野菜容器１３の引き出しに伴って往路Ｙ１を移動し、５３Ｂの位置において物品載置用底板３１が最大上昇位置となり、野菜容器１３の引き出し最終位置において５３Ｃの位置となり、物品載置用底板３１が下降位置となる。
【００４１】
この最終位置５３Ｃは復路Ｙ２の始端であり、この野菜容器１３の引き出しが終了した状態から引き出し式扉１４を後方へ押して野菜容器１３を野菜室６内へ収納させることにより、ローラ５３がガイド溝４０の復路Ｙ２に沿って移動し、引き出し式扉１４が閉じたとき、ローラ５３は初期位置５３Ａへ復帰する。この初期位置５３Ａは次の引き出しがスムースに行われるために、往路Ｙ１の始端位置である。
【００４２】
野菜容器１３の引き出しが終了した状態では物品載置用底板３１は下降した位置にあるため、復路Ｙ２では物品載置用底板３１は下降した位置を保持したままである。このため、野菜容器１３を押し込む収納動作中に背高物品収納部３２に収納した物品Ｐが野菜室６の前面開口上縁６Ａに当接することはない。
【００４３】
上記のように、ガイド溝４０の形状によって物品載置用底板３１の上昇時点や上昇高さを設定できるため、野菜室６の大きさや野菜容器１３の大きさ、底板作動機構３０による物品載置用底板３１の上昇程度等によって、種々の形態に設定すればよい。
【００４４】
なお、物品載置用底板３１の左右両側では、物品載置用底板３１が下がった位置と上昇した位置において、背高物品収納部３２の左右側壁との間の隙間が大きくなり、この隙間へ他物が嵌り込んで物品載置用底板３１の動作を邪魔する虞がある。これの防止策として、図４の（ａ）図及び（ｂ）図に示すように、物品載置用底板３１よりも左右方向へ長い物品載置用遊動板６０を物品載置用底板３１に載置し、物品載置用遊動板６０によって前記隙間を覆うように構成する。この物品載置用遊動板６０の左右端部は、背高物品収納部３２の左右側壁のガイド部６１に緩く嵌った状態であり、背高物品収納部３２に収納する物品Ｐは、この物品載置用遊動板６０上に載置される。これによって、上記のように連結部材３８を介して物品載置用底板３１が可動支持部材４９、５０の回動を伴う引っ張り動作によって上下動するとき、物品載置用遊動板６０はガイド部６１に案内されて上下動し、物品Ｐが上下動することとなる。
【００４５】
本発明は、野菜容器に限らずその他の容器に適用できるものであり、冷蔵庫の他に、冷凍庫、温蔵庫、恒温庫等種々の貯蔵庫にも適用できるものである。また物品載置用底板の上下動を行う底板作動機構は上記の構成に限定されない。したがって、本発明は、本発明の技術的範囲を逸脱しない限り種々の変更が考えられ、それに係る種々の実施形態を包含するものである。
【００４６】
【発明の効果】
本発明によって、容器に収納した物品が、背が低い場合にもその取り出しが容易になる物品収納装置を提供できる。
【００４７】
請求項２の発明によって、容器を途中まで引き出すことにより背高物品収納部に収納した物品が上昇するため、その背高物品収納部に収納した物品の背が低い場合にもその取り出しが容易になる。そして、容器を大きく引き出した状態では、物品載置用底板が下降して背高物品収納部に収納した物品が下降するため、容器の奥に収納した物品の取り出しが容易となる。
【００４８】
請求項３及び４の発明によって、容器に収納した物品が、背が低い場合にもその取り出しが容易になる物品収納装置を提供できる。そして、作動部材はガイド溝に沿って回動することによって物品載置用底板が上下動するため、容器の引き出し及び収納の抵抗が少なく安定した動作が得られる構成となる。
【００４９】
請求項５の発明によって、容器を途中まで引き出すことにより背高物品収納部に収納した物品が上昇するため、その背高物品収納部に収納した物品の背が低い場合にもその取り出しが容易になる。そして、容器を大きく引き出した状態では、物品載置用底板が下降して背高物品収納部に収納した物品が下降するため、容器の奥に収納した物品の取り出しが容易となる。そして、ガイド溝の湾曲頂上の位置が前後中央か或いは前方寄りか後方よりかによって、物品載置用底板の最大上昇位置を決めることができるため、容器の形状や貯蔵室の大きさなどによって適正な位置に物品載置用底板の最大上昇位置を定めることが容易となる。
【００５０】
請求項６の発明によって、上記効果に加えて、背高物品収納部に収納された物品が上昇しても、貯蔵室の開口上縁に当接しない状態での容器の引き出しを行うようにできる。
【００５１】
また、最大上昇位置で背高物品収納部に収納した物品が下降しないような安定を保つためには、容器の最終引き出し位置の若干手前で物品載置用底板が最大上昇位置となり、容器の最終引き出し位置までその状態を保つように、ガイド溝の終端部に容器の引き出し方向に沿った直線部分を形成し、この直線部分にローラが位置したときを容器の最終引き出し位置とすればよい。
【００５２】
また、実施形態のように、本発明の容器を冷蔵庫の野菜容器とし、この野菜容器の前側に背高物品収納部を設け、ここの物品載置用底板が野菜容器の引き出しに伴って上昇又は上下動するように構成すれば、野菜容器の使用性が向上し、そこに収納したペットボトル等の取り出しとその奥の野菜の取り出しとが便利な状態で収納できることとなる。

The connection between the operating member 35 and the second connecting member 44 may be configured such that a guide pin 45 is provided on the second connecting member 44 and a long hole 46 is formed in the operating member 35.
[0024]
The left and right sides of the article placement bottom plate 31 are supported by movable support members 49 and 50 rotatably attached to the bottom wall 39 of the vegetable compartment 6 by shaft supports 47 and 48, respectively. The connection portions with the movable support members 49 and 50 are rotatably connected by shaft support portions 51 and 52, respectively.
[0025]
In the guide groove 40 and the fitting portion 41 following the guide groove 40, a roller 53 rotatably mounted on a shaft extending downward from the operating member 35 is loosely fitted in the guide groove 40. As will be described later, when the roller 53 moves along the guide groove 40 in accordance with the operation of pulling out and storing the vegetable container 13 forward, the roller 53 contacts the side wall of the guide groove 40 and rotates. In this configuration, the contact resistance in the fitting portion 41 is reduced.
[0026]
First, referring to FIGS. 1 to 4, the operation of the article storage device of the present invention will be described below. As shown in FIGS. 3 and 4, the guide groove 40 has a curved shape that is curved in an arc shape or an arc shape. When the vegetable container 13 is stored in the vegetable compartment 6 and the drawer-type door 14 is closed, the roller 53 is located at the rear end of the guide groove 40, and the operating member 35 is in the state of 35A shown in FIG. This state is an initial position, and the article placing bottom plate 31 is in a lowered state, is located below the tall article storage unit 32, and is a tall article P placed on the article placing bottom plate 31. Are kept so as not to protrude from the vegetable container 13.
[0027]
In this state, when the handle of the door 14 is grasped and the door 14 is pulled forward, the vegetable container 13 is pulled out together with the door 14 by the support of the rail or roller device 28. As the vegetable container 13 is pulled out, the roller 53 is guided along the guide groove 40, whereby the operating member 35 rotates about the shaft support 36. With the rotation of the operating member 35, the article placing bottom plate 31 is pulled to the left in FIG. 4 and to the right in FIG. 3 via the connecting member 38, and the article placing bottom plate 31 is moved by the movable support member. It rises with the rotation of 49 and 50.
[0028]
With this pull-out operation, the article mounting bottom plate 31 gradually rises toward the maximum rising position. When the roller 42 reaches the curved top portion 40A of the guide groove 40, the article mounting bottom plate 31 is at the maximum raised position. The state of the operating member 35 that has reached the maximum raised position is indicated by 35B in FIG. The tall article P also rises as the article placement bottom plate 31 rises to the maximum elevation position, but the tall article P is pulled out of the vegetable container 13 to the front opening upper edge 6A of the vegetable compartment 6 while the vegetable container 13 is being pulled out. The shape of the guide groove 40 is formed so as not to abut. The guide groove 40 is pulled out of the vegetable container 13 so that the tall article storage portion 32 is pulled out to the outside area of the vegetable compartment 6, that is, the article placement bottom plate 31 is pulled out to the outside area of the vegetable compartment 6. In this state, a curved shape is formed in which the top portion 40A is determined so as to reach the maximum ascending position. The tall articles P that have reached the maximum ascending position protrude above the vegetable container 13 and thus can be easily taken out.
[0029]
When the vegetable container 13 is further pulled out from the state where the article mounting bottom plate 31 has been raised to the maximum raised position, the roller 53 moves along the curve of the guide groove 40, and the operating member 35 rotates in the return direction. The article mounting bottom plate 31 is lowered, and the operating member 35 reaches the state of 35C in FIG. This is the final state in which the vegetable container 13 is pulled out, and the article mounting bottom plate 31 is in the same position as the state where the vegetable container 13 is stored in the vegetable room 6 and the drawer type door 14 is closed. For this reason, the tall articles P descend and do not hinder the removal of the food stored in the vegetable storage chamber 33 on the back side of the tall article storage section 32, and the food stored in the deep section of the vegetable storage chamber 33 is removed. Easy to take out. T1 shown in FIG. 3 indicates a linear distance drawn from the state in which the drawer-type door 14 is closed to the maximum ascending position, and T2 indicates a linear distance from the maximum ascending position to the end of the extraction of the vegetable container 13.
[0030]
By pushing the drawer-type door 14 backward from the state where the drawer of the vegetable container 13 has been pulled out and storing the vegetable container 13 in the vegetable room 6, the roller 53 moves along the curve of the guide groove 40, and the above-described outward movement is performed. The operation member 35 is rotated by an operation reverse to the above, and the article placing bottom plate 31 once rises to the maximum rising position, and then returns to the initial position when the drawer type door 14 is closed.
[0031]
As described above, since the article P stored in the tall article storage section 32 rises by pulling out the vegetable container 13 halfway, the tall article P stored in the tall article storage section 32, as well as the tall article P, It is easy to take it out even in the case of an article having a low value. Then, in a state where the vegetable container 13 is largely pulled out, the article placement bottom plate 31 is lowered and the articles P stored in the tall article storage section 32 are lowered, so that the articles stored in the back of the vegetable container 13 can be taken out. It will be easier.
[0032]
In order to maintain stability so that the article P stored in the tall article storage section 32 does not descend at the maximum ascending position, the article placing bottom plate 31 becomes the maximum ascending position slightly before the final pull-out position of the vegetable container 13, It is desirable to keep that state until the vegetable container 13 is finally pulled out. For this reason, it is sufficient to form a straight portion 40B along the drawing direction of the vegetable container 13 at the terminal end of the guide groove 40 as shown in FIG.
[0033]
In FIG. 5, the form of the guide groove 40 is different from that described above. That is, the guide groove 40 has a curved shape from the initial position to the maximum rising position, and the guide groove 40 has a linear shape along the drawing direction of the vegetable container 13 from the maximum rising position to the final drawing position of the vegetable container 13. 53A is an initial position of the roller 53, 53B is a position of the roller 53 at a maximum ascending position where the article mounting bottom plate 31 first reaches, and 53C is a position of the roller 53 at a final position where the vegetable container 13 is pulled out. . With this configuration, the article mounting bottom plate 31 gradually rises while the roller 53 moves from the position 53A to the position 53B as the vegetable container 13 is pulled out, reaches the maximum rising position at the position 53B, and the roller 53 moves to the position 53B. To 53C, it remains at the maximum raised position.
[0034]
In the form of FIG. 5, the operation from the initial position to the intermediate position of the drawer of the vegetable container 13 is the same as that of FIGS. Since the bottom plate 31 remains at the maximum raised position and the articles P stored in the tall article storage section 32 are kept at the raised position when the vegetable container 13 is pulled out halfway, there is an effect that it can be easily taken out at any time.
[0035]
By pushing the drawer-type door 14 backward from the state in which the drawer of the vegetable container 13 has been pulled out and storing the vegetable container 13 in the vegetable room 6, the straight line of the guide groove 40 is obtained by the operation reverse to the above-mentioned operation in the forward direction Y1. The roller 53 moves along the portion, and the operating member 35 rotates from a position past the linear portion, and the article mounting bottom plate 31 gradually descends from the maximum rising position. Then, when the drawer type door 14 is closed, it returns to the initial position. Y1 indicates a forward path, and Y2 indicates a return path.
[0036]
FIG. 6 shows another embodiment of the guide groove 40. In this case, the guide groove 40 is linear along the drawing direction of the vegetable container 13 from the initial position to the middle of the drawing of the vegetable container 13, and thereafter the guide groove 40 has a curved shape to the drawing position of the vegetable container 13. is there. 53A is an initial position of the roller 53, 53B is a position where the article mounting bottom plate 31 starts to rise, and 53C is a position of the roller 53 at a final position where the vegetable container 13 is pulled out. With this configuration, the article mounting bottom plate 31 does not move up while the roller 53 moves from the position of 53A to 53B as the vegetable container 13 is pulled out, and the article mounting bottom plate 31 moves when the roller 53 moves from 53B to 53C. The placing bottom plate 31 gradually rises, and reaches the maximum rising position at the position of 53C.
[0037]
The drawer-type door 14 is pushed backward from the state where the drawer of the vegetable container 13 has been pulled out, and the vegetable container 13 is stored in the vegetable room 6. The roller 53 moves along, the operating member 35 rotates, and the article mounting bottom plate 31 gradually descends from the maximum raised position, and returns to the initial position when the drawer type door 14 is closed. Y1 indicates a forward path, and Y2 indicates a return path.
[0038]
In the embodiment of FIG. 6, since the article placing bottom plate 31 does not rise from the initial position to the middle position of the drawer of the vegetable container 13, the tall articles P are also located at lower positions in the tall article storage section 32 in this range. , And does not come into contact with the upper edge of the front opening of the vegetable compartment 6 while the vegetable container 13 is being pulled out. Then, by further pulling out the vegetable container 13, the article placing bottom plate 31 gradually rises toward the final position, and the article placing bottom plate 31 becomes the maximum rising position at the final drawing position of the vegetable container 13. .
[0039]
In order to maintain stability such that the articles P stored in the tall article storage section 32 do not drop at the maximum ascending position, the article mounting bottom plate 31 becomes the maximum ascending position slightly before the final withdrawal position of the vegetable container 13. It is desirable to maintain that state until the vegetable container 13 is finally pulled out. For this reason, as shown by the dotted line in FIG. 6, a straight line portion 40B is formed at the end of the guide groove 40 along the drawing direction of the vegetable container 13, and when the roller 53 is positioned on the straight line portion 40B (see the dotted line 53C). Position) may be set as the final withdrawal position of the vegetable container 13.
[0040]
FIG. 7 shows still another embodiment of the guide groove 40. In this case, the operation of the outward path Y1 from the initial position to the final position of extracting the vegetable container 13 is the same as that shown in FIGS. That is, the form of the forward path Y1 of the guide groove 40 is the same as that shown in FIGS. 1 to 4, but a straight return path Y2 along the drawing direction of the vegetable container 13 is separately formed in parallel with the forward path Y1. New in that. In the guide groove 40, the outward path Y1 and the return path Y2 are continuous at both ends and have a substantially D-shaped shape as a whole. Then, the roller 53 moves on the outward path Y1 with the withdrawal of the vegetable container 13 from the initial position 53A, the article mounting bottom plate 31 becomes the maximum ascending position at the position of 53B, and 53C at the final withdrawal position of the vegetable container 13. Position, and the article mounting bottom plate 31 is at the lowered position.
[0041]
The final position 53C is the start end of the return path Y2. When the drawer-type door 14 is pushed rearward from the state where the drawing of the vegetable container 13 is completed, the vegetable container 13 is stored in the vegetable room 6, and the roller 53 is guided by the guide groove. The roller 53 returns to the initial position 53A when it moves along the return path Y2 of 40 and the drawer type door 14 is closed. This initial position 53A is the start position of the forward path Y1 because the next drawing is performed smoothly.
[0042]
In the state where the extraction of the vegetable container 13 has been completed, the article mounting bottom plate 31 is at the lowered position, so that the article mounting bottom plate 31 keeps the lowered position on the return path Y2. For this reason, the articles P stored in the tall article storage section 32 do not come into contact with the upper edge 6A of the front opening of the vegetable compartment 6 during the storing operation of pushing the vegetable container 13.
[0043]
As described above, since the height and height of the bottom of the article placement bottom plate 31 can be set by the shape of the guide groove 40, the size of the vegetable compartment 6, the size of the vegetable container 13, and the article placement by the bottom plate operation mechanism 30. Various forms may be set according to the degree of elevation of the bottom plate 31 and the like.
[0044]
In addition, on the left and right sides of the article mounting bottom plate 31, the gap between the left and right side walls of the tall article storage unit 32 becomes large at the position where the article mounting bottom plate 31 is lowered and the position where it is raised. There is a possibility that another object may be fitted and hinder the operation of the article mounting bottom plate 31. As a countermeasure for this, as shown in FIGS. 4A and 4B, an article placing floating plate 60 longer in the left-right direction than the article placing bottom plate 31 is attached to the article placing bottom plate 31. The clearance is covered by the floating plate 60 for placing articles. The left and right ends of the article placing floating plate 60 are loosely fitted in the guide portions 61 on the left and right side walls of the tall article storage section 32, and the article P stored in the tall article storage section 32 is It is mounted on the mounting floating plate 60. As a result, when the article mounting bottom plate 31 moves up and down by the pulling operation involving the rotation of the movable support members 49 and 50 via the connecting member 38 as described above, the article mounting floating plate 60 is moved to the guide portion 61. And the article P moves up and down, and the article P moves up and down.
[0045]
