Abstract

<P>PROBLEM TO BE SOLVED: To simplify the production process of a heat-insulated door and reduce cost. <P>SOLUTION: Extension parts 20 are integrally fitted to both door caps 19 fitted to two sides of a door front surface material 14, and a door rear surface material 27 is fitted to these extension parts 20 and the folded parts 15a and 15b of two sides of the door front surface material 14 with screws 29. The folded parts 15a and 15b of the door front surface material 14 may be formed only two sides to which the door cap 19 is not fitted. Therefore, unlike a conventional structure in which the folded parts are formed on all four sides of the door front surface material, the number of steps for forming the folded parts can be reduced by an amount equivalent to two sides and, accordingly, the production process of the heat-insulated door can be simplified and a cost can be lowered. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、断熱扉を備えた貯蔵庫に関する。
【0002】
【従来の技術】
従来、貯蔵庫の断熱扉としては、例えば図6に示す構成のものがある。すなわち、鋼板製の扉表側面材1は、ほぼ矩形状をなしていて、左右2辺に裏側へ折り返された折返し部2a,2bを一体に有すると共に、上下の2辺にも裏側へ折り返された折返し部2c,2dを一体に有する構成とし、これら各折返し部2a〜2dにそれぞれねじ孔3を形成する。扉表側面材1の上下の2辺には、合成樹脂製の扉キャップ4,4を装着する。そして、扉表側面材1の裏側に合成樹脂製の扉裏側面材5を配置し、この扉裏側面材5を、上記各折り返し部2a〜2dに前記ねじ孔3を利用してねじ6によりねじ止めする。扉裏側面材5には、発泡性断熱材を注入するための注入孔7を形成している。これら扉表側面材1と、2個の扉キャップ4,4と、扉裏側面材5とにより扉外殻8を形成し、上記注入孔7から扉外殻8の内部の空間部に発泡性断熱材(図示せず)を注入し、これを発泡充填させることにより断熱扉を構成する。なお、このような構成の断熱扉の裏側の周縁部には、図示はしないがシール用のマグネットガスケットが取り付けられる。
【0003】
なお、本件発明の課題とは直接関係はないが、例えば冷蔵庫における断熱扉においては、次のような構成のものがある。すなわち、この断熱扉は、ほぼ矩形状をなし対向する2辺に裏側へ折り返された折返し部を一体に有する鋼板製の扉表側面材と、この扉表側面材の前記折返し部がない2辺に装着される合成樹脂製の2個の扉キャップと、扉表側面材の裏側に配置される合成樹脂製の扉裏側面材とにより扉外殻を形成すると共に、この扉外殻の内部の空間部に発泡性断熱材を発泡充填して構成されている(例えば、特許文献1参照)。
【0004】
【特許文献1】
特開2000−88444号公報(段落番号[0017]〜[0023]、図1)
【0005】
【発明が解決しようとする課題】
上記した図6の従来構成のものでは、次のような欠点がある。すなわち、扉表側面材1には、扉裏側面材5をねじ止めするために、4辺すべてに折返し部2a〜2dを形成するようにしている。このため、扉表側面材1において、それら折返し部2a〜2dを形成するための製造工程が多くなり、ひいては断熱扉の製造工程が多くなると共に、コストが高くなるという欠点がある。
【0006】
本発明は上記事情に鑑みてなされたものであり、その目的は、断熱扉の製造工程を簡素化することができると共に、コストを低減化することが可能な貯蔵庫を提供するにある。
【0007】
【課題を解決するための手段】
上記した目的を達成するために、請求項1の発明は、ほぼ矩形状をなし対向する2辺に裏側へ折り返された折返し部を一体に有した扉表側面材と、この扉表側面材の前記折返し部がない2辺に装着される2個の扉キャップと、前記扉表側面材の裏側に配置される扉裏側面材とから扉外殻を形成すると共に、この扉外殻の内部の空間部に発泡性断熱材を発泡充填して構成される断熱扉を備えた貯蔵庫において、前記断熱扉における前記両扉キャップに、前記扉裏側面材と重なり合う延出部を一体に設け、前記扉裏側面材を、前記延出部と前記折返し部にねじ止めする構成としたことを特徴とする。
【0008】
上記した構成によれば、扉表側面材の2辺に装着される両扉キャップに、扉裏側面材をねじ止めするための延出部を一体に設けたので、扉表側面材の折返し部としては、扉キャップを装着しない2辺のみに形成すれば良い。このため、扉表側面材の4辺すべてに折返し部を形成していた従来構成とは違い、折返し部を形成する工程が2辺分少なくなり、その分、断熱扉の製造工程を簡素化できると共に、コストを低減化することが可能となる。
【0009】
請求項2の発明は、前記延出部において前記扉裏側面材と対向する面で、かつ前記扉裏側面材をねじ止めする部分に対応する部位に、溝部を形成したことを特徴とする。
これによれば、扉裏側面材を扉キャップの延出部にねじ止めする際に、その延出部においてねじの先端が、前記溝部により滑り難くなり、位置決めし易くなるため、ねじ止め作業が行い易くなる。
【0010】
【発明の実施の形態】
以下、本発明の一実施例について図1ないし図5を参照して説明する。
まず、図2には、貯蔵庫としてストッカー11が示されている。このストッカー11の本体12は、図示はしないが上面が開口した貯蔵室を有していて、上部に、その貯蔵室を開閉する断熱扉13が後端部を支点にして回動可能に枢支されている。断熱扉13は、横長の矩形状をなしている。
【0011】
図1には上記断熱扉13の分解斜視図が示され、図3には、この断熱扉13の要部の断面図が示されている。断熱扉13の表側を形成する扉表側面材14は、鋼板により横長の矩形状に形成されていて、周囲の4辺のうち、対向する前後の2辺に、裏側(図1において上側)へ折り返された折返し部15a,15bを一体に形成している。前後の両折返し部15a,15bには、それぞれ複数個のねじ孔16が形成され、また、前側の折返し部15aの左右方向の中央部にはハンドル17が取り付けられている。なお、扉表側面材14の内面にはポリエチレン製のシート18が配置されている。
【0012】
上記扉表側面材14の4辺のうち、上記折返し部15a,15bが形成されていない左右の2辺には、合成樹脂製の扉キャップ19,19を嵌合により装着している。これら各扉キャップ19には、相手側に向けて突出するように延出部20が一体に設けられている。その延出部20の裏面側(図1において上面側)には、複数箇所にそれぞれ複数本の細い溝部21(図4及び図5参照)が形成されている。
【0013】
扉表側面材14の裏側には、当該扉表側面材14の裏側の開口部を塞ぐように背面紙22を両面テープ23を介して取り付けている。両面テープ23は、折返し部15a,15bと両扉キャップ19の延出部20とに枠状となるように貼り付けている。背面紙22の中央部には、円形の孔24が形成されている。なお、背面紙22の周縁部は、ビニールテープ25で裏側から押え付けている。
【0014】
背面紙22の裏側には、矩形枠状のガスケット26と矩形板状の合成樹脂製の扉裏側面材27を配置している。ガスケット26には、マグネット26a(図3参照)が設けられている。扉裏側面材27は、周縁部にフランジ部27aを有していて、これらフランジ部27aが上記両折返し部15a,15b及び両延出部20に対して裏側から重なり合う形状をなしている。各フランジ部27aには、折返し部15a,15bの各ねじ孔16に対応する部位、及び各延出部20の各溝部21に対応する部位に位置させてねじ挿通孔28が形成されている。
【0015】
扉裏側面材27は、ガスケット26の内部に挿入し、図3に示すように、フランジ部27aにてガスケット26の一部を上記各延出部20及び上記折返し部15a,15bに押え付ける状態で、ねじ29によりそれら各延出部20及び折返し部15a,15bに固定している。この場合、折返し部15a,15bに対応するねじ29は、フランジ部27aのねじ挿通孔28を挿通すると共に背面紙22を貫通し、折返し部15a,15bのねじ孔16にねじ込むことにより取り付けられ、延出部20に対応するねじ29は、フランジ部27aのねじ挿通孔28を挿通すると共に背面紙22を貫通し、延出部20にねじ込むことにより取り付けられる(図3参照)。上記扉裏側面材27の中央部には、背面紙22の孔24に対応する円形の注入孔30が形成されている。
【0016】
ここで、扉表側面材14と、左右両側の扉キャップ19と、扉裏側面材27とにより、断熱扉13の扉外殻31を形成している。そして、発泡性断熱材の原液を、上記注入孔30から孔24を通して、背面紙22と扉表側面材14との間に形成される空間部32に注入して発泡させることにより、その空間部32に発泡性断熱材33が充填される。以上により、断熱扉13が構成されている。
【0017】
上記した実施例によれば、次のような効果を得ることができる。
断熱扉13において、扉表側面材14の2辺に装着される両扉キャップ19に、扉裏側面材27をねじ止めするための延出部20を一体に設けたので、扉表側面材14の折返し部15a,15bとしては、扉キャップ19を装着しない2辺のみに形成すれば良い。このため、扉表側面材の4辺すべてに折返し部を形成していた従来構成とは違い、折返し部を形成する工程が2辺分少なくなり、その分、断熱扉13の製造工程を簡素化できると共に、コストを低減化することが可能となる。
【0018】
また、各扉キャップ19の延出部20には、扉裏側面材27のねじ挿通孔28と対応する部分に位置させて、複数の溝部21を形成しているので、扉裏側面材27をその延出部20にねじ止めする際に、その延出部20においてねじ29の先端が、前記溝部21により滑り難くなり、位置決めし易くなるため、ねじ止め作業が行い易くなる。
【0019】
本発明は、上記した実施例にのみ限定されるものではなく、次のように変形または拡張できる。
本発明は、ストッカー11の断熱扉13に限られず、冷蔵庫や温蔵庫の断熱扉にも適用できる。
【0020】
【発明の効果】
以上の説明から明らかなように、本発明によれば、扉表側面材の2辺に装着される両扉キャップに、扉裏側面材をねじ止めするための延出部を一体に設けたので、扉表側面材の折返し部としては、扉キャップを装着しない2辺のみに形成すれば良い。このため、扉表側面材の4辺すべてに折返し部を形成していた従来構成とは違い、折返し部を形成する工程が2辺分少なくなり、その分、断熱扉の製造工程を簡素化できると共に、コストを低減化することが可能となる。

The door front side surface member 14 forming the front side of the heat-insulating door 13 is formed in a horizontally long rectangular shape by a steel plate, and, among four surrounding sides, two opposite front and rear sides and a rear side (upward in FIG. 1). The folded portions 15a and 15b are integrally formed. A plurality of screw holes 16 are formed in each of the front and rear folded portions 15a and 15b, and a handle 17 is attached to the center of the front folded portion 15a in the left-right direction. In addition, a sheet 18 made of polyethylene is arranged on the inner surface of the door surface side member 14.
[0012]
Of the four sides of the door front side member 14, two door caps 19, 19 made of synthetic resin are fitted by fitting to the two left and right sides where the folded portions 15a, 15b are not formed. Each of the door caps 19 is integrally provided with an extension 20 so as to protrude toward the other party. A plurality of narrow grooves 21 (see FIGS. 4 and 5) are formed at a plurality of locations on the back side (upper side in FIG. 1) of the extension portion 20.
[0013]
On the back side of the door front side member 14, a back paper 22 is attached via a double-sided tape 23 so as to close the opening on the back side of the door front side member 14. The double-sided tape 23 is attached to the folded portions 15a and 15b and the extending portion 20 of both door caps 19 so as to form a frame. A circular hole 24 is formed in the center of the back paper 22. The peripheral edge of the back paper 22 is pressed from the back side with a vinyl tape 25.
