Description

【０００１】
【発明の属する技術分野】
本発明は、例えばホテルやレストランの厨房などに設けられると共に、前面に開口する断熱性の本体の側方に設けられた機械室と、本体から機械室の上側に渡って設けられたトップテーブルを有して、本体の前面開口を引出式の断熱扉で開閉するよう構成された所謂引出式のアンダーカウンター型冷却貯蔵庫に関するものである。
【０００２】
【従来の技術】
従来より例えばホテルやレストランの厨房に設けられる所謂アンダーカウンター型の業務用冷蔵庫は、断熱箱体などから構成された断熱性の本体と、この本体の側方に設けられ、圧縮機や凝縮器などが設置される機械室と、本体と機械室の上側に渡って設けられたトップテーブルを備えている。そして、本体の前面開口は回動自在の観音開き式断熱扉などにて開閉自在に閉塞していた。
【０００３】
しかしながら、係る断熱扉の場合には、断熱扉を開放して本体内の食品などを取り出し、或いは、確認する際、腰を屈めて覗き込まなければならず、作業性が極めて悪いものであった。そのため、本体の前面開口を引出式の断熱扉にて開閉自在としたものも開発されている。係る冷蔵庫では本体内に納出自在の食品収納容器を断熱扉の裏側に保持させているので、断熱扉の引き出し開放操作によって容器ごと食品を引き出すことができる利点がある。
【０００４】
【発明が解決しようとする課題】
このような引出式の断熱扉を備えた従来の冷蔵庫では、断熱扉は上下に多数段、左右に複数列設けられる。また、各断熱扉の食品収納容器は比較的薄型のホテルパンと称される上面開口の容器にて構成されていた。ところが、近年では断熱扉の段数を減らす代わりに一枚当たりの大きさを拡大し、容器として比較的大型のバスケットを断熱扉に保持させることにより、従来の観音開き式扉の冷蔵庫と同等の物品収納性を実現したいと云う要求がある。
【０００５】
しかしながら、断熱扉一枚当たりの大きさを拡大して、より重量のある食品をバスケットに収納すると、上側の断熱扉を引き出した際、重心が大きく前方に移動するため、冷蔵庫全体が前方に転倒してしまうと云う問題があった。
【０００６】
本発明は、係る従来の技術課題を解決するために成されたものであり、引出式の断熱扉を備えた冷却貯蔵庫において、断熱扉を引き出した際の転倒を効果的に防止することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１の発明の冷却貯蔵庫は、前面に開口する断熱性の本体と、該本体の側方に設けられた機械室と、本体と機械室の上側に渡って設けられたトップテーブルと、上下複数段、左右複数列配設され、本体の前面開口を開閉自在に閉塞する引出式の断熱扉と、各断熱扉に保持された状態で本体より納出自在とされた物品収納用容器部材と、断熱扉の引き出し操作を規制するための規制手段とを備え、上側に位置する複数の断熱扉のうちの何れかの断熱扉が引き出された場合、規制手段が、当該引き出された断熱扉の左右方向に並ぶ残余の断熱扉の少なくとも何れかの引き出し操作を禁止するものであって、規制手段は、上側に位置して左右に並ぶ複数の断熱扉に渡って設けられ、回動自在とされた可動片と、該可動片に設けられ、各断熱扉にそれぞれ係脱自在とされた複数の係合部とから構成され、何れかの断熱扉が閉成した状態で、当該断熱扉は各係合部が各断熱扉より離間する方向に可動片を回動させて保持すると共に、全ての断熱扉が引き出された状態では、各係合部が各断熱扉に係合する方向に可動片は回動することを特徴とする。
【０００８】
請求項１の発明によれば、前面に開口する断熱性の本体と、該本体の側方に設けられた機械室と、本体と機械室の上側に渡って設けられたトップテーブルと、上下複数段、左右複数列配設され、本体の前面開口を開閉自在に閉塞する引出式の断熱扉と、各断熱扉に保持された状態で本体より納出自在とされた物品収納用容器部材とを備えた冷却貯蔵庫において、断熱扉の引き出し操作を規制するための規制手段を設け、上側に位置する複数の断熱扉のうちの何れかの断熱扉が引き出された場合、規制手段が、当該引き出された断熱扉の左右方向に並ぶ残余の断熱扉の少なくとも何れかの引き出し操作を禁止するので、上下複数段ある断熱扉のうちの上側の断熱扉が全て引き出されてしまうことを禁止することができる。
【０００９】
これにより、上側の断熱扉は少なくとも何れかが閉成した状態を維持されるので、断熱扉一枚当たりの物品収納重量が大きくなった場合にも、重心の前方への移動を抑制し、冷却貯蔵庫が転倒する不都合を効果的に防止することができるようになる。
【００１０】
特に、規制手段は、上側に位置して左右に並ぶ複数の断熱扉に渡って設けられ、回動自在とされた可動片と、該可動片に設けられ、各断熱扉にそれぞれ係脱自在とされた複数の係合部とから構成され、何れかの断熱扉が閉成した状態で、当該断熱扉は各係合部が各断熱扉より離間する方向に可動片を回動させて保持すると共に、全ての断熱扉が引き出された状態では、各係合部が各断熱扉に係合する方向に可動片は回動するようにしたので、例えば上側において左右に並ぶ断熱扉を一つずつ引き出していった場合、最後の断熱扉が引き出される際に可動片が回動して係合部が当該断熱扉に係合するので、当該断熱扉の引き出し操作を阻止することができる。
【００１１】
また、上側において左右に並ぶ全ての断熱扉を同時に引き出そうとしても、やはり可動片が回動して各係合部が各断熱扉に係合するので、この場合には全ての断熱扉の引き出し操作が禁止される。このように、簡単な構成にて上側で左右に並ぶ複数の断熱扉の全てが引き出されてしまうことを確実に阻止することができるようになるので、冷却貯蔵庫の転倒防止を安価に達成することができるようになるものである。
【００１２】
請求項２の発明の冷却貯蔵庫は、請求項１において本体下部に設けられた脚部材と、本体下部から前方に突出して設けられた転倒防止部材とを備えたことを特徴とする。
【００１３】
請求項２の発明によれば、請求項１に加えて本体下部に設けられた脚部材と、本体下部から前方に突出して設けられた転倒防止部材とを備えているので、断熱扉を引き出した際に万一冷却貯蔵庫が前方に傾こうとしても、本体下部から前方に突出して設けられた転倒防止部材が冷却貯蔵庫の傾斜を阻止することになる。これにより、上側の断熱扉の引き出し操作に伴う冷却貯蔵庫の転倒をより一層確実に防止することができるようになるものである。
【００１４】
請求項３の発明の冷却貯蔵庫は、請求項１において本体下部に設けられた後脚部材と、本体下部から前方に突出して設けられた前脚部材とを備えたことを特徴とする。
【００１５】
請求項３の発明によれば、請求項１に加えて本体下部に設けられた後脚部材と、本体下部から前方に突出して設けられた前脚部材とを備えているので、断熱扉を引き出した際に万一冷却貯蔵庫が前方に傾こうとしても、本体下部から前方に突出して設けられた前脚部材が冷却貯蔵庫の傾斜を阻止することになる。これにより、上側の断熱扉の引き出し操作に伴う冷却貯蔵庫の転倒をより一層確実に防止することができるようになるものである。
【００１６】
【発明の実施の形態】
以下、図面に基づき本発明の実施形態を詳述する。図１は本発明の冷却貯蔵庫の一実施例の業務用冷蔵庫１の斜視図、図２は冷蔵庫１の縦断側面図、図３は冷蔵庫１の平断面図である。実施例の冷蔵庫１は例えばホテルやレストランの厨房で使用される所謂アンダーカウンター型の冷蔵庫であり、前面に開口する横長矩形状の断熱箱体から本体２が構成されている。
【００１７】
この本体２の向かって左側には圧縮機３や凝縮器４、図示しない冷却器などから成る冷却装置を設置するための機械室６が構成されている。また、本体２の天面にはステンレス製のトップテーブル７が取り付けられ、機械室６の上方まで渡って一連の作業台を構成している。本体２の底面四隅には脚８・・・が取り付けられており、それぞれ高さ調節機構を備えている。このうち、後側左右の脚８が後脚部材となる。尚、９は本体２から下方に引き出されたドレン排水パイプである。
【００１８】
そして、本体２内に前面に開口する冷蔵室１１が構成され、この冷蔵室１１の前面開口は上下方向の中央に位置する横仕切部材１２と、左右方向の中央に位置する縦仕切部材１３によって上下二段、左右二列の四区画に仕切られている。そして、この仕切られた各開口は比較的大型の引出式の断熱扉１４、１４及び１５、１５によってそれぞれ開閉自在に閉塞されている。この場合、断熱扉１４、１４、１５、１５は上下二段、左右二列で配設されており、断熱扉１５、１５が下側左右二列、断熱扉１４、１４がそれらの上側二列で配置されている。
【００１９】
各断熱扉１４、１４、１５、１５の裏面左右には、後方に延在するレール１６、１６が取り付けられ、各レール１６、１６の後端はそれらに渡る連結部材１７にて連結され、断熱扉１４、１５の後方に全体として枠状の保持部を構成している。そして、各断熱扉１４、１４、１５、１５のレール１６、１６間には、上面に開口する物品収納用容器部材としての比較的大型のバスケット１８が位置し、両レール１６、１６上に取り外し自在に保持されている。これら断熱扉１４、１５及びレール１６、１６、連結部材１７、バスケット１８にて引出装置が構成される（図３はバスケット１８が取り外された状態を示す）。
【００２０】
尚、冷蔵室１１の内壁面及び、縦仕切部材１３の後方には各断熱扉１４、１５のレール１６、１６後端部外側面に取り付けられたローラ２１が転動自在に係合される図示しない本体側レールが取り付けられており、各本体側レールの前端部には、レール１６が滑動自在に載置されるこれも図示しない本体側ローラが取り付けられている。これにより、各断熱扉１４、１５はバスケット１８をそれぞれ保持した状態で本体２内より前方にそれぞれ引き出し自在とされ、それによって、各バスケット１８も冷蔵室１１内より納出自在とされている。また、２２は機械室６の前面を開閉自在に閉塞するパネルである。
【００２１】
前記冷却器にて冷却された冷気は冷蔵室１１の機械室６側の側面に取り付けられたグリル２３から冷蔵室１１内に吹き出され、冷蔵室１１内を冷却した後、再びグリル２３に吸い込まれる。これにより、冷蔵室１１内は所定の冷蔵温度に冷却される。
【００２２】
一方、本体２の前側の脚８、８のそれぞれの内側近傍には、本体２の底面前部から前方に突出する転倒防止部材２６、２６が底面に取り付けられて設けられている。この転倒防止部材２６、２６が前脚部材となる。転倒防止部材２６は、その前面が上方の断熱扉１５の前面と略面一となる位置まで延在しており、その先端部下面には傘型の高さ調節可能な接地部材２７が設けられている。
【００２３】
尚、脚８・・・は冷蔵庫１を据え付けた際に床面に接地するように高さ調節されるが、各転倒防止部材２６、２６も断熱扉１５、１５の下側において床面に接地するように高さ調節されるものである。このとき、転倒防止部材２６は冷蔵庫１の外形寸法内に納められているので、設置スペースを拡大することがない。また、このように上下二段の扉構成とし、バスケット１８も大型化することにより、通常の観音開き式扉と同等の物品収納性を実現している。
【００２４】
他方、上側左右の断熱扉１４、１４の相隣接するそれぞれのレール１６、１６後方に対応する位置の冷蔵室１１背面には、本発明の規制手段を構成する可動片３１が取り付けられている。この可動片３１は図４に示す如く上側左右の断熱扉１４、１４の隣接するレール１６、１６間に位置してそれらに渡る寸法を有しており、図６に示す如く左右端には前方に突出して下側に鋭角に屈曲された一対の係合部３２、３２が形成されている。
【００２５】
各図において３３は冷蔵室１１の背面に取り付けられた取付部材であり、可動片３１は上下方向略中央部の左右縁部に位置する軸３５、３５において、この取付部材３３の左右縁部から前方に突出した腕部３３Ａに回動自在に枢支されている。また、係合部３２、３２が形成されている関係上、定常状態では可動片３１は図５に実線で示す如く上側（係合部３２、３２側）が前方となるように傾斜し、下端の後向き折曲部３４が取付部材３３に当接している。
【００２６】
また、前記上側左右の断熱扉１４、１４の隣接するレール１６、１６の後部には、図４に示すような矩形状の係合孔３７がそれぞれ穿設されている。ここで、各レール１６、１６は、断熱扉１４、１４が閉成されたときに可動片３１の軸３５より上側に当接する位置関係とされており、且つ、図５中実線で示す如く可動片３１の上側が前方となるように傾斜した状態で、各係合部３２、３２が各係合孔３７、３７に係合する位置関係とされている。
【００２７】
以上の構成で、図１に示すように上側左右の断熱扉１４、１４が双方とも閉成された状態では、両断熱扉１４、１４の相隣接するレール１６、１６の双方が可動片３１に当接し、図５中破線で示す如く可動片３１の上側（係合部３２、３２側）を後方に押して係合部３２、３２が若干上側に向くように保持している。この状態では、係合部３２、３２はレール１６、１６の係合孔３７から上方に離間している。
【００２８】
この状態から図３、図４に示すように例えば向かって左側の断熱扉１４のみを引き出しても、向かって右側の断熱扉１４が可動片３１を図５中破線の状態に保持しているので、係合部３２はレール１６の係合孔３７から離間しているので、左側の断熱扉１４は自由に引き出し操作できる。これは図１の状態から向かって右側の断熱扉１４のみを引き出す際にも同様である。
【００２９】
次に、上述の如く向かって左側の断熱扉１４を引き出した状態で、更に、向かって右側の断熱扉１４を引き出そうとすると、今度は可動片３１を図５中破線の状態に保持しているものが無くなるため、レール１６の前方への移動に伴って、可動片３１は図５中矢印Ｃの如く上側が前方に移動する方向に回動し始める。そして、レール１６が図５中Ｂ寸法だけ少許前方に移動した段階で、係合部３２（この場合右側の係合部）がレール１６の係合孔３７内に進入し、係合する。これにより、向かって右側の断熱扉１４は引き出し不能となる。
【００３０】
これは右側の断熱扉１４を引き出した状態で左側の断熱扉１４を引き出す際にも同様であり、当該左側の断熱扉１４の引き出しは阻止される。また、図１の状態から左右の断熱扉１４、１４を同時に引き出そうとすると、同様に可動片３１が回動するため、今度は両断熱扉１４、１４が引き出し操作不能となる。即ち、一旦両断熱扉１４、１４を閉成した後は、可動片３１の動作を不能としない限り、左右の断熱扉１４、１４を同時に引き出した状態をつくることはできない。
【００３１】
これにより、実施例の如く上側の断熱扉１４、１４を比較的大型とし、且つ、大型のバスケット１８を保持させても、断熱扉１４は何れか一方のみしか開くことができないので、冷蔵庫１の重心の前方への移動は極力抑制される。更に、本発明では左右の転倒防止部材２６、２６が断熱扉１５、１５の下方まで突出しているので、万一冷蔵庫１全体が前方に傾こうとしても、転倒は阻止される。
【００３２】
尚、実施例では本体２の四隅の脚８・・・の他に転倒防止部材２６、２６を取り付けたが、それに限らず、前側の脚８、８を省略して転倒防止部材２６、２６を前側の脚（前脚部材）としても用いてもよい。
【００３３】
また、実施例では上下二段、左右二列の断熱扉１４、１４、１５、１５を設けたが、それに限らず、更に多くの段数、列数（左右に三列など）で設けてもよい。例えば三列設けた場合には、可動片３１は隣接する断熱扉間にそれぞれ二カ所設けられることになる。その場合には、左右端の断熱扉を同時に引き出した状態及び中央の断熱扉のみを引き出した状態は構成できるものの、全ての断熱扉を引き出した状態は構成できなくなる。更に、実施例では上側の断熱扉１４、１４の引き出し操作を規制したが、下側の断熱扉１５、１５も同様に規制してもよい。
【００３４】
【発明の効果】
以上詳述した如く請求項１の発明によれば、前面に開口する断熱性の本体と、該本体の側方に設けられた機械室と、本体と機械室の上側に渡って設けられたトップテーブルと、上下複数段、左右複数列配設され、本体の前面開口を開閉自在に閉塞する引出式の断熱扉と、各断熱扉に保持された状態で本体より納出自在とされた物品収納用容器部材とを備えた冷却貯蔵庫において、断熱扉の引き出し操作を規制するための規制手段を設け、上側に位置する複数の断熱扉のうちの何れかの断熱扉が引き出された場合、規制手段が、当該引き出された断熱扉の左右方向に並ぶ残余の断熱扉の少なくとも何れかの引き出し操作を禁止するので、上下複数段ある断熱扉のうちの上側の断熱扉が全て引き出されてしまうことを禁止することができる。
【００３５】
これにより、上側の断熱扉は少なくとも何れかが閉成した状態を維持されるので、断熱扉一枚当たりの物品収納重量が大きくなった場合にも、重心の前方への移動を抑制し、冷却貯蔵庫が転倒する不都合を効果的に防止することができるようになる。
【００３６】
特に、規制手段は、上側に位置して左右に並ぶ複数の断熱扉に渡って設けられ、回動自在とされた可動片と、該可動片に設けられ、各断熱扉にそれぞれ係脱自在とされた複数の係合部とから構成され、何れかの断熱扉が閉成した状態で、当該断熱扉は各係合部が各断熱扉より離間する方向に可動片を回動させて保持すると共に、全ての断熱扉が引き出された状態では、各係合部が各断熱扉に係合する方向に可動片は回動するようにしたので、例えば上側において左右に並ぶ断熱扉を一つずつ引き出していった場合、最後の断熱扉が引き出される際に可動片が回動して係合部が当該断熱扉に係合するので、当該断熱扉の引き出し操作を阻止することができる。
【００３７】
また、上側において左右に並ぶ全ての断熱扉を同時に引き出そうとしても、やはり可動片が回動して各係合部が各断熱扉に係合するので、この場合には全ての断熱扉の引き出し操作が禁止される。このように、簡単な構成にて上側で左右に並ぶ複数の断熱扉の全てが引き出されてしまうことを確実に阻止することができるようになるので、冷却貯蔵庫の転倒防止を安価に達成することができるようになるものである。
【００３８】
請求項２の発明によれば、請求項１に加えて本体下部に設けられた脚部材と、本体下部から前方に突出して設けられた転倒防止部材とを備えているので、断熱扉を引き出した際に万一冷却貯蔵庫が前方に傾こうとしても、本体下部から前方に突出して設けられた転倒防止部材が冷却貯蔵庫の傾斜を阻止することになる。これにより、上側の断熱扉の引き出し操作に伴う冷却貯蔵庫の転倒をより一層確実に防止することができるようになるものである。
【００３９】
請求項３の発明によれば、請求項１に加えて本体下部に設けられた後脚部材と、本体下部から前方に突出して設けられた前脚部材とを備えているので、断熱扉を引き出した際に万一冷却貯蔵庫が前方に傾こうとしても、本体下部から前方に突出して設けられた前脚部材が冷却貯蔵庫の傾斜を阻止することになる。これにより、上側の断熱扉の引き出し操作に伴う冷却貯蔵庫の転倒をより一層確実に防止することができるようになるものである。

BACKGROUND OF THE INVENTION
The present invention includes, for example, a machine room provided in a kitchen of a hotel or restaurant, a machine room provided on the side of a heat-insulating main body that opens to the front surface, and a top table provided from the main body to the upper side of the machine room. The present invention relates to a so-called drawer-type undercounter type cooling storage that is configured to open and close the front opening of the main body with a drawer-type heat insulating door.
[0002]
[Prior art]
So-called undercounter type commercial refrigerators that are conventionally provided in, for example, hotel and restaurant kitchens, have a heat-insulating main body composed of a heat-insulating box, etc. And a top table provided over the main body and the machine room. And the front opening of the main body was closed so that it could be opened and closed with a rotatable double-spread type heat insulating door.
[0003]
However, in the case of such a heat insulating door, when the heat insulating door is opened and the food in the main body is taken out or confirmed, the waist must bend and look into it, and the workability is extremely poor. . For this reason, there has been developed a structure in which the front opening of the main body can be opened and closed with a drawer type heat insulating door. In such a refrigerator, since the food storage container that can be delivered into the main body is held behind the heat insulating door, there is an advantage that the food can be pulled out together with the container by the drawer opening operation of the heat insulating door.
[0004]
[Problems to be solved by the invention]
In a conventional refrigerator provided with such a drawer-type heat insulating door, the heat insulating doors are provided in a plurality of stages on the top and bottom and in a plurality of rows on the left and right. Moreover, the food storage container of each heat insulation door was comprised by the container of the upper surface opening called a comparatively thin hotel bread. However, in recent years, instead of reducing the number of steps of the heat insulating door, the size per sheet is increased, and a relatively large basket as a container is held in the heat insulating door, so that the storage of goods equivalent to a conventional double door refrigerator can be stored. There is a demand to realize the sex.
[0005]
However, if the size of each insulated door is increased and heavier food is stored in the basket, the center of gravity moves greatly forward when the upper insulated door is pulled out, so the entire refrigerator falls forward. There was a problem of doing so.
[0006]
The present invention was made in order to solve the conventional technical problems, and aims to effectively prevent the overturn when the heat insulating door is pulled out in a cooling storage room having a drawer type heat insulating door. And
[0007]
[Means for Solving the Problems]
The cooling storage of the invention of claim 1 includes a heat-insulating main body opened to the front surface, a machine room provided on the side of the main body, a top table provided over the main body and the machine room, and upper and lower A drawer-type heat insulating door that is arranged in a plurality of stages and in a plurality of rows on the left and right sides, and that closes the front opening of the main body so as to be openable and closable; And a regulating means for regulating the drawer operation of the heat insulation door, and when any one of the plurality of heat insulation doors located on the upper side is withdrawn, the regulation means is provided for the drawn heat insulation door . The operation of restricting at least one of the remaining heat insulating doors arranged in the left-right direction is prohibited, and the restricting means is provided over a plurality of heat insulating doors arranged on the left and right and is rotatable. Movable pieces and provided on the movable pieces, Each of the heat insulating doors is a movable piece in a direction in which each engaging portion is separated from each heat insulating door in a state where any heat insulating door is closed. In a state where all the heat insulating doors are pulled out, the movable piece rotates in the direction in which each engaging portion engages with each heat insulating door .
[0008]
According to invention of Claim 1, the heat insulating main body opened to the front surface, the machine room provided on the side of the main body, the top table provided over the main body and the machine room, and a plurality of upper and lower sides A drawer-type heat insulating door that is arranged in a plurality of stages, left and right, and closes the front opening of the main body so as to be openable and closable, and an article storage container member that can be delivered from the main body while being held by each heat insulating door. In the provided cooling storage, a restricting means for restricting the operation of pulling out the heat insulating door is provided, and when any one of the plurality of heat insulating doors located on the upper side is pulled out, the restricting means is pulled out. Since the operation of pulling out at least one of the remaining heat insulating doors arranged in the left-right direction of the heat insulating door is prohibited, it is possible to prohibit the upper heat insulating door from being pulled out of the plurality of upper and lower heat insulating doors. .
[0009]
As a result, at least one of the upper heat insulating doors is maintained in a closed state. Therefore, even when the article storage weight per one heat insulating door increases, the forward movement of the center of gravity is suppressed and cooling is performed. It becomes possible to effectively prevent the inconvenience that the storage falls .
[0010]
In particular, the restricting means is provided over a plurality of heat insulating doors located on the upper side and arranged on the left and right sides, a movable piece that is rotatable, and a movable piece that is provided on the movable piece and can be engaged with and disengaged from each heat insulating door. In a state where any one of the heat insulating doors is closed, the heat insulating door rotates and holds the movable piece in a direction in which each engaging portion is separated from each heat insulating door. At the same time, when all the heat insulating doors are pulled out, the movable piece is rotated in the direction in which each engaging portion engages with each heat insulating door. When the heat insulating door is pulled out, the movable piece rotates when the last heat insulating door is pulled out, and the engaging portion engages with the heat insulating door, so that the operation of pulling out the heat insulating door can be prevented.
[0011]
Moreover, even if it is going to pull out all the heat insulation doors lined up on the left and right simultaneously on the upper side, the movable piece still rotates and each engaging portion engages with each heat insulation door. In this case, all the heat insulation doors are pulled out. Operation is prohibited. As described above, since it becomes possible to reliably prevent all of the plurality of heat insulating doors arranged on the upper and lower sides from being pulled out with a simple configuration, it is possible to achieve the prevention of overturning of the cooling storage at low cost. Will be able to.
[0012]
According to a second aspect of the present invention, there is provided a cooling storage facility comprising the leg member provided at the lower portion of the main body and the overturn prevention member provided to project forward from the lower portion of the main body.
[0013]
According to the second aspect of the invention, in addition to the first aspect, the leg member provided at the lower part of the main body and the fall prevention member provided to protrude forward from the lower part of the main body are provided. In this case, even if the cooling storage is inclined forward, the tipping prevention member provided to protrude forward from the lower part of the main body prevents the cooling storage from being inclined. As a result, it is possible to more reliably prevent the cooling storage from overturning due to the operation of pulling out the upper heat insulating door.
[0014]
According to a third aspect of the present invention, there is provided a cooling storage facility comprising the rear leg member provided at the lower part of the main body and the front leg member provided to project forward from the lower part of the main body.
[0015]
According to the invention of claim 3, in addition to claim 1, the rear leg member provided at the lower part of the main body and the front leg member provided to protrude forward from the lower part of the main body are provided. Even if the cooling storage is going to tilt forward, the front leg member protruding forward from the lower part of the main body prevents the cooling storage from tilting. As a result, it is possible to more reliably prevent the cooling storage from overturning due to the operation of pulling out the upper heat insulating door.
[0016]

It is divided into four sections of two stages, upper and lower, and two rows on the left and right. Each partitioned opening is closed by a relatively large drawer-type heat insulating door 14, 14, and 15, 15 so as to be freely opened and closed. In this case, the heat insulating doors 14, 14, 15, 15 are arranged in two upper and lower rows and two left and right rows, the heat insulating doors 15, 15 are the lower left and right two rows, and the heat insulating doors 14, 14 are the upper two rows thereof. Is arranged in.
[0019]
Rails 16 and 16 extending rearward are attached to the left and right sides of the rear surfaces of the heat insulating doors 14, 14, 15, and 15, and the rear ends of the rails 16 and 16 are connected by connecting members 17 extending over them. A frame-shaped holding portion is configured as a whole behind the doors 14 and 15. And between the rails 16 and 16 of each heat insulation door 14,14,15,15, the comparatively large-sized basket 18 as an article storage container member opened on an upper surface is located, and it removes on both rails 16,16. It is held freely. The heat insulating doors 14 and 15 and the rails 16 and 16, the connecting member 17, and the basket 18 constitute a drawer device (FIG. 3 shows a state where the basket 18 is removed).
[0020]
In addition, on the inner wall surface of the refrigerating chamber 11 and the rear of the vertical partition member 13, rollers 21 attached to the outer surfaces of the rails 16 and 16 rear end portions of the heat insulating doors 14 and 15 are rotatably engaged. A main body side rail is attached, and a main body side roller (not shown) on which the rail 16 is slidably mounted is attached to the front end of each main body side rail.

Thereby, the inside of the refrigerator compartment 11 is cooled to a predetermined refrigerator temperature.
[0022]
On the other hand, in the vicinity of the inside of each of the legs 8, 8 on the front side of the main body 2, fall prevention members 26, 26 protruding forward from the front part of the bottom surface of the main body 2 are provided attached to the bottom surface. These fall prevention members 26 and 26 become front leg members. The toppling prevention member 26 extends to a position where the front surface thereof is substantially flush with the front surface of the upper heat insulating door 15, and an umbrella-shaped height-adjustable grounding member 27 is provided on the lower surface of the tip portion. ing.
[0023]
The height of the legs 8 is adjusted so as to be grounded to the floor when the refrigerator 1 is installed, but the fall prevention members 26 and 26 are also grounded to the floor below the heat insulating doors 15 and 15. The height is adjusted so that At this time, since the fall-preventing member 26 is housed within the outer dimensions of the refrigerator 1, the installation space is not enlarged. In addition, since the door has a two-stage upper and lower structure and the basket 18 is increased in size, the same article storage property as that of a normal double door is realized.
[0024]
On the other hand, the movable piece 31 which comprises the control means of this invention is attached to the refrigerator compartment 11 back surface of the position corresponding to each rail 16 and 16 back of the adjacent heat insulation doors 14 and 14 of upper left and right. As shown in FIG. 4, the movable piece 31 is located between the adjacent rails 16 and 16 of the upper left and right heat insulating doors 14 and 14, and has a dimension extending over them. As shown in FIG. A pair of engaging portions 32, 32 that are bent downward at an acute angle are formed.
[0025]
In each figure, 33 is an attachment member attached to the back surface of the refrigerator compartment 11, and the movable piece 31 has shafts 35, 35 positioned at the left and right edges of the substantially central portion in the vertical direction from the left and right edges of the attachment member 33. The arm portion 33A protruding forward is pivotally supported. Further, because the engaging portions 32 and 32 are formed, in a steady state, the movable piece 31 is inclined so that the upper side (the engaging portions 32 and 32 side) is forward as shown by the solid line in FIG. The rearward bent portion 34 is in contact with the mounting member 33.
[0026]
Further, rectangular engagement holes 37 as shown in FIG. 4 are formed in the rear portions of the rails 16 and 16 adjacent to the upper left and right heat insulating doors 14 and 14, respectively. Here, the rails 16 and 16 are in a positional relationship where they abut on the upper side of the shaft 35 of the movable piece 31 when the heat insulating doors 14 and 14 are closed, and are movable as indicated by solid lines in FIG. In a state in which the upper side of the piece 31 is inclined so as to be forward, the engaging portions 32 and 32 are in a positional relationship to engage with the engaging holes 37 and 37.
[0027]
With the above configuration, when the upper left and right heat insulating doors 14 and 14 are both closed as shown in FIG. 1, both adjacent rails 16 and 16 of both heat insulating doors 14 and 14 become movable pieces 31. As shown by the broken line in FIG. 5, the upper side (engagement parts 32, 32 side) of the movable piece 31 is pushed backward to hold the engagement parts 32, 32 slightly upward. In this state, the engaging portions 32 and 32 are spaced upward from the engaging holes 37 of the rails 16 and 16.
[0028]
3 and FIG. 4, for example, even if only the left heat insulating door 14 is pulled out, the right heat insulating door 14 holds the movable piece 31 in the state of the broken line in FIG. Since the engaging portion 32 is separated from the engaging hole 37 of the rail 16, the left heat insulating door 14 can be freely pulled out. This is the same when pulling out only the right insulating door 14 from the state of FIG.
[0029]
Next, when the left heat insulating door 14 is pulled out as described above and the right heat insulating door 14 is further pulled out, the movable piece 31 is held in the state of the broken line in FIG. Since there is nothing, the movable piece 31 starts to rotate in the direction in which the upper side moves forward as indicated by the arrow C in FIG. 5 as the rail 16 moves forward. Then, at the stage where the rail 16 has moved a small amount forward in the direction of B in FIG. 5, the engaging portion 32 (in this case, the right engaging portion) enters the engaging hole 37 of the rail 16 and engages. As a result, the right heat insulating door 14 cannot be pulled out.
[0030]
This is the same when the left heat insulating door 14 is pulled out with the right heat insulating door 14 pulled out, and the left heat insulating door 14 is prevented from being pulled out. Further, when the left and right heat insulating doors 14 and 14 are simultaneously pulled out from the state of FIG. 1, the movable piece 31 is similarly rotated, so that the heat insulating doors 14 and 14 cannot be pulled out this time. That is, once both the heat insulating doors 14 and 14 are closed, the left and right heat insulating doors 14 and 14 cannot be drawn out at the same time unless the movable piece 31 is disabled.
[0031]
Accordingly, even if the upper heat insulating doors 14 and 14 are made relatively large as in the embodiment and the large basket 18 is held, only one of the heat insulating doors 14 can be opened. The forward movement of the center of gravity is suppressed as much as possible. Furthermore, in the present invention, since the left and right fall prevention members 26 and 26 protrude to the lower side of the heat insulating doors 15 and 15, even if the entire refrigerator 1 is inclined forward, the fall is prevented.
[0032]
In the embodiment, the fall prevention members 26 and 26 are attached in addition to the legs 8 at the four corners of the main body 2. However, the present invention is not limited to this, and the front legs 8 and 8 are omitted and the fall prevention members 26 and 26 are provided. It may also be used as a front leg (front leg member).
[0033]
In the embodiment, the heat insulating doors 14, 14, 15, 15 are provided in two upper and lower rows and two rows on the left and right sides. . For example, when three rows are provided, the movable pieces 31 are provided at two locations between adjacent heat insulating doors. In that case, the state in which the left and right heat insulating doors are pulled out simultaneously and the state in which only the central heat insulating door is pulled out can be configured, but the state in which all the heat insulating doors are pulled out cannot be configured. Furthermore, in the embodiment, the operation of pulling out the upper heat insulating doors 14 and 14 is restricted, but the lower heat insulating doors 15 and 15 may be restricted in the same manner.
[0034]
【The invention's effect】
As described above in detail, according to the first aspect of the present invention, the heat-insulating main body opened to the front surface, the machine room provided on the side of the main body, and the top provided over the main body and the machine room. A table, a plurality of upper and lower steps, and a plurality of left and right rows, a drawer-type heat insulating door that closes the front opening of the main body so that it can be opened and closed, and an article storage that can be delivered from the main body while being held by each heat insulating door In the cooling storage provided with a container member, a restricting means for restricting the operation of pulling out the heat insulating door is provided, and when any one of the plurality of heat insulating doors located on the upper side is pulled out, the restricting means However, since the operation of pulling out at least one of the remaining heat insulating doors arranged in the left-right direction of the drawn out heat insulating door is prohibited, all the heat insulating doors on the upper side among the upper and lower heat insulating doors are all drawn out. Can be banned.
[0035]
As a result, at least one of the upper heat insulating doors is maintained in a closed state. Therefore, even when the article storage weight per one heat insulating door increases, the forward movement of the center of gravity is suppressed and cooling is performed. It becomes possible to effectively prevent the inconvenience that the storage falls .
[0036]
In particular, the restricting means is provided over a plurality of heat insulating doors located on the upper side and arranged on the left and right sides, a movable piece that is rotatable, and a movable piece that is provided on the movable piece and can be engaged with and disengaged from each heat insulating door. In a state where any one of the heat insulating doors is closed, the heat insulating door rotates and holds the movable piece in a direction in which each engaging portion is separated from each heat insulating door. At the same time, when all the heat insulating doors are pulled out, the movable piece is rotated in the direction in which each engaging portion engages with each heat insulating door. When the heat insulating door is pulled out, the movable piece rotates when the last heat insulating door is pulled out, and the engaging portion engages with the heat insulating door, so that the operation of pulling out the heat insulating door can be prevented.
[0037]
Moreover, even if it is going to pull out all the heat insulation doors lined up on the left and right at the upper side, the movable piece still rotates and each engaging portion engages with each heat insulation door. Operation is prohibited. As described above, since it becomes possible to reliably prevent all of the plurality of heat insulating doors arranged on the upper and lower sides from being pulled out with a simple configuration, it is possible to achieve the prevention of overturning of the cooling storage at low cost. Will be able to.
[0038]
According to the second aspect of the present invention, in addition to the first aspect, the leg member provided at the lower part of the main body and the fall prevention member provided to protrude forward from the lower part of the main body are provided. In this case, even if the cooling storage is inclined forward, the tipping prevention member provided to protrude forward from the lower part of the main body prevents the cooling storage from being inclined. As a result, it is possible to more reliably prevent the cooling storage from overturning due to the operation of pulling out the upper heat insulating door.
[0039]
According to the invention of claim 3, in addition to claim 1, the rear leg member provided at the lower part of the main body and the front leg member provided to protrude forward from the lower part of the main body are provided. Even if the cooling storage is going to tilt forward, the front leg member protruding forward from the lower part of the main body prevents the cooling storage from tilting. As a result, it is possible to more reliably prevent the cooling storage from overturning due to the operation of pulling out the upper heat insulating door.
