【発明が解決しようとする課題】
しかしながら、上記従来の構成では、容器２の動きを規制するため後部フレーム４が必要であり、コスト的に高くなるという課題を有していた。
【０００６】
本発明は上記従来の課題を解決するもので、後部フレームを廃止しても容器を固定できる引出し式扉を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明の請求項１に記載の発明は、前面が開口された断熱箱体の内部を仕切体により複数の区画室に区画し、前記区画室の前面開口部に設けられる断熱扉に引出し可能にフレームを設け、前記フレームに上方から容器を支持するものにおいて、前記容器の側面に突起部を設けるとともに、前記突起部に対向した前記フレームに切欠き部を設け、前記切欠き部の前後引出し方向に平面部を設けたものであり、容器の側面に設けた突起部がフレームの切欠き部に嵌め込まれることで容器が規制され前後方向にずれることはない。そして切欠き部の前後引出し方向に平面部を設けているので容器の側面に設けた突起部が引出し扉開閉時の衝撃により損傷あるいは削られることもない。
【０００８】
請求項２に記載の発明は、請求項１に記載の発明において、フレームの切欠き部に設ける平面部は、フレームの切欠き部分を折り曲げて切欠き部を形成しながら平面部を一体に成形するものであり、一体に折り曲げて成形することで、製造コストを低減することができる。
【０００９】
請求項３に記載の発明は、請求項１または２に記載の発明において、フレームの切欠き部に設ける平面部は、前後方向の両端部に形成するものであり、扉を開放した時の衝撃と扉を閉めた時の衝撃の両方向の力に対して損傷あるいは削れを防止できる。
【００１０】
請求項４に記載の発明は、請求項１から請求項３のいずれか一項に記載の発明において、突起部の奥行寸法と切欠き部の奥行寸法を略同一としたものであり、容器の側面に設けた突起部がフレームの切欠き部に嵌め込まれた時のガタツキを最小限に抑えることができ、扉開閉時の突起部への衝撃を低減することができる。
【００１１】
請求項５に記載の発明は、請求項１から請求項４のいずれか一項に記載の発明において、容器の側面に設ける突起部は、側面から見て下辺を短辺とする台形形状としたものであり、容器の側面に設けた突起部をフレームの切欠き部に嵌め込む時の前後ばらつきを吸収でき容器の設置が容易となる。
【００１２】
請求項６に記載の発明は、請求項１から請求項５のいずれか一項に記載の発明において、容器の側面に設けた突起部の前後引出し方向に平面部を設けたものであり、フレームの切欠き部に設けた平面部との相乗効果により容器の側面に設けた突起部の引出し扉開閉時の衝撃による損傷あるいは削れをさらに防止できる。
【００１３】
【発明の実施の形態】
以下、本発明による冷蔵庫の実施の形態について、図面を参照しながら説明する。
【００１４】
（実施の形態１）
図１は、本発明の実施の形態１による冷蔵庫の側面断面図、図２は同実施の形態による冷蔵庫の野菜室の斜視図、図３は同実施の形態による冷蔵庫の野菜室のフレームの切欠き部の要部拡大図、図４は同実施の形態による冷蔵庫の野菜室の容器の側面に設けた突起部の要部拡大図である。
【００１５】
図１において、１０は冷蔵庫本体で、鋼板で形成した外箱１１と樹脂で成形した内箱１２の内部に樹脂発泡したウレタンフォーム１３で断熱箱体を形成し前面を開口している。そして断熱仕切壁１４により上部貯蔵室と下部貯蔵室に区画している。上部貯蔵室の上方には冷蔵室１５、上部貯蔵室の下方には仕切板１６を介して野菜室１７を有する。また、下部貯蔵室は断熱仕切壁１９を介して上下に区画し、上方には切替室１８と製氷室（図示せず）、下部貯蔵室の下方には冷凍室２０を有している。また冷蔵庫本体１０の下部後方には機械室を有し内部に圧縮機（図示せず）を配置している。
【００１６】
また、冷蔵室扉２１は冷蔵室１５の前面開口部に位置し、一端を支点として回動するヒンジ式の扉である。２２、２３、２４、はそれぞれ、野菜室１７、切替室１８、冷凍室２０の前方開口部に位置する引出し式の扉である。
【００１７】
図２において、野菜室扉２２には庫内側奥行方向左右に野菜容器２５を上方から支持する一対のフレーム２６が設けられている。フレーム２６は上下にフランジを有する断面コの字状に形成され、上フランジ２７には切欠き部２８を有している。また、フレーム２６の奥部に設けた穴２９にローラ３０の軸が取付けられている。一方、野菜容器２５の上面開口部周縁にはケースフランジ３１を有し、両側面には突起部３２を設け、突起部３２がフレーム２６の切欠き部２８に嵌合するようになっている。また、ローラ３０は断熱箱体の側面に設けたレール（図示せず）に支持され回動し、野菜室扉２２および野菜容器２５を前後に引出し可能にしている。
【００１８】
また、図３に示すように、フレーム２６の上フランジ２７に形成する切欠き部２８の前後引出し方向には平面部３３を設けており、平面部３３はフレーム２６の上フランジ２７の切欠き部分を折り曲げて切欠き部２８を形成しながら平面部３３を一体に成形している。
【００１９】
また、図４に示すように、突起部３２の奥行寸法Ｂと切欠き部２８の奥行寸法Ａを略同一寸法としている。なお、切欠き部２８の奥行寸法Ａを突起部３２の奥行寸法Ｂよりも若干大きめに設定することが望ましい。
【００２０】
上記構成により、野菜室扉２２開閉時、野菜容器２５の側面に設けた突起部３２がフレーム２６の切欠き部２８に嵌め込まれることで野菜容器２５が規制され前後方向にずれることはない。そして切欠き部２８の前後引出し方向に平面部３３を設けているので野菜容器２５の側面に設けた突起部３２が野菜室扉２２開閉時の衝撃により損傷あるいは削られることもなく長期耐久性に優れたものとなる。
【００２１】
また、フレーム２６の切欠き部２８に設ける平面部３３は、フレーム２６の上フランジ２７の切欠き部分を折り曲げて切欠き部２８を形成しながら平面部３３を一体に成形しているので、作業工数、部品点数を削減でき製造コストを低減することができる。
【００２２】
また、突起部３２の奥行寸法Ｂと切欠き部２８の奥行寸法Ａを略同一寸法としているので、野菜容器２５の側面に設けた突起部３２がフレーム２６の切欠き部２８に嵌め込まれた時のガタツキを最小限に抑えることができるので、扉開閉時の突起部３２への衝撃を低減することができ損傷あるいは削れ防止を図ることが出来る。
【００２３】
また、図５に示すように、フレーム２６の切欠き部２８に設ける平面部３３、３４は、前後方向の両端部に形成してもよい。この場合、扉を開放した時の衝撃と扉を閉めた時の衝撃の両方向の力に対して損傷あるいは削れを防止できる。
【００２４】
なお、本実施の形態では、野菜室扉２２について説明したが、これに限定されるものでなく、切替室扉２３、冷凍室扉２４など内部の容器が連動して引き出される形態のものであれば同様の作用効果を得られるものである。
【００２５】
（実施の形態２）
図６は、本発明の実施の形態２による冷蔵庫の引出し容器の側面に設けた突起部の拡大斜視図である。なお、実施の形態１と同一構成については説明を省略し、異なる部分のみ説明する。
【００２６】
図において、ケースフランジ３１の両側面に設けた突起部３５は、側面から見て下辺を短辺とする台形形状としたもので、突起部３５の受側であるフレーム２６に設けた切欠き部２８の平面部３３も、突起部３５の台形形状に係合する形状としている。
【００２７】
上記構成により、野菜容器２５をフレーム２６に嵌め込む時の前後ばらつきを吸収でき、野菜容器２５の設置が容易となる。
【００２８】
（実施の形態３）
図７は、本発明の実施の形態３による冷蔵庫の引出し容器の側面に設けた突起部の拡大斜視図である。なお、実施の形態１と同一構成については説明を省略し、異なる部分のみ説明する。
【００２９】
図において、ケースフランジ３１の両側面に設けた突起部３６は、前後引出し方向に平面部を設けたものである。
【００３０】
上記構成により、フレーム２６の切欠き部２８に設けた平面部３３との相乗効果により野菜容器２５の側面に設けた突起部３２の引出し扉開閉時の衝撃による損傷あるいは削れをさらに確実に防止できる。
【００３１】
【発明の効果】
以上説明したように請求項１に記載の発明は、前面が開口された断熱箱体の内部を仕切体により複数の区画室に区画し、前記区画室の前面開口部に設けられる断熱扉に引出し可能にフレームを設け、前記フレームに上方から容器を支持するものにおいて、前記容器の側面に突起部を設けるとともに、前記突起部に対向した前記フレームに切欠き部を設け、前記切欠き部の前後引出し方向に平面部を設けることにより、容器が規制され前後方向にずれることはない。そして切欠き部の前後引出し方向に平面部を設けたことにより容器の側面に設けた突起部が引出し扉開閉時の衝撃により損傷あるいは削られることもなく長期信頼性が高まる。
【００３２】
また、請求項２に記載の発明は、請求項１に記載の発明において、フレームの切欠き部に設ける平面部は、フレームの切欠き部分を折り曲げて切欠き部を形成しながら平面部を一体に成形するものであり、一体に折り曲げて成形することで、製造コストを低減することができる。
【００３３】
また、請求項３に記載の発明は、請求項１または２に記載の発明において、フレームの切欠き部に設ける平面部は、前後方向の両端部に形成するものであり、扉を開放した時の衝撃と扉を閉めた時の衝撃の両方向の力に対して損傷あるいは削れを防止できる。
【００３４】
また、請求項４に記載の発明は、請求項１から請求項３のいずれか一項に記載の発明において、突起部の奥行寸法と切欠き部の奥行寸法を略同一としたものであり、容器の側面に設けた突起部がフレームの切欠き部に嵌め込まれた時のガタツキを最小限に抑えることができ、扉開閉時の突起部への衝撃を低減することができる。
【００３５】
また、請求項５に記載の発明は、請求項１から請求項４のいずれか一項に記載の発明において、容器の側面に設ける突起部は、側面から見て下辺を短辺とする台形形状としたものであり、容器の側面に設けた突起部をフレームの切欠き部に嵌め込む時の前後ばらつきを吸収でき容器の設置が容易となる。
【００３６】
また、請求項６に記載の発明は、請求項１から請求項５のいずれか一項に記載の発明において、容器の側面に設けた突起部の前後引出し方向に平面部を設けたものであり、フレームの切欠き部に設けた平面部との相乗効果により容器の側面に設けた突起部の引出し扉開閉時の衝撃による損傷あるいは削れをさらに防止できる。
