【発明の属する技術分野】
本発明は、前面に開閉自在な扉を有する商品収納庫が、板金製の外箱とその外箱の内面に沿って配設された断熱板により構成され、かつ、上下方向に沿う断熱仕切り板によって前面が開口する複数の商品収納室に区画されている自動販売機の断熱構造に関する。
【０００２】
【従来の技術】
このような自動販売機の断熱構造は、断熱仕切り板により区画された各商品収納室において、冷熱や温熱が逃げないように密封するためのもので、従来、図１８の（イ）に示すような構造が採用されていた。
すなわち、従来では、商品収納庫７の背面に配設される断熱背板３が、１枚の板状体で構成されて外箱１の背板１４に沿って取り付けられ、また、商品収納庫７の底面に配設される断熱底板４も、１枚の板状体で構成されて外箱１の収納庫底板１８に沿って取り付けられ、その断熱背板３と断熱底板４の庫内側の面に対して、断熱仕切り板８の端面が当接されて取り付けられていた。
【０００３】
【発明が解決しようとする課題】
ところが、外箱１の背板１４や収納庫底板１８は、比較的薄い金属製の板材で構成されることが多く、外力の作用などによって「反り」が生じる可能性があり、特に、面積の大きな背板１４側では、その「反り」の発生も顕著である。
背板１４に「反り」が生じると、断熱背板３が前後方向に変形や位置ズレを起こし、図１８の（ロ）に示すように、断熱背板３と断熱仕切り板８の端面との間に隙間Ｓが生じて、各商品収納室における密封性が阻害されるおそれがある。
そこで、断熱背板３と断熱仕切り板８端面との間の隙間Ｓを埋めるため、特別にパッキンを取り付けたり、図１７に示すように、外箱１の背板１４にスポット溶接などによって固着された板金部品から形成された階段状のチャンネル材４２に対して、断熱仕切り板８の後端縁に固着された金属製の板からなる横倒しＬ字状の固定金具４３を、複数のネジ止めによって一体連結したりするなどして、断熱背板３と断熱仕切り板８端面との間に隙間Ｓが生じないような対策を講じていたのが実情であり、場合によっては、断熱底板４と断熱仕切り板８との間でも同様な対策を講じる必要がある。
したがって、上述した従来構造によれば、パッキンや、チャンネル材４２、固定金具４３などが必要で、部品点数が多くなり、しかも、そのパッキンや、チャンネル材４２、固定金具４３の取り付け作業も必要となって、コストアップを招くおそれがあった。
【０００４】
本発明は、このような従来の問題点に着目したもので、その目的は、部品点数の増加を抑制し、かつ、取り付け作業の簡素化を図りながら、各商品収納室における密封性を確保できる自動販売機の断熱構造を提供することにある。
【０００５】
【課題を解決するための手段】
請求項１の発明の特徴構成は、前面に開閉自在な扉を有する商品収納庫が、板金製の外箱とその外箱の内面に沿って配設された断熱板により構成され、かつ、上下方向に沿う断熱仕切り板によって前面が開口する複数の商品収納室に区画されている構成において、前記商品収納庫の背面に配設される断熱背板が、前記複数の商品収納室に対応して複数に分割され、前記断熱仕切り板が、その分割された断熱背板間に挟み込まれた状態で配設されている。
【０００６】
請求項１の発明の特徴構成によれば、商品収納庫の背面に配設される断熱背板が、複数の商品収納室に対応して複数に分割され、商品収納庫を複数の商品収納室に区画する断熱仕切り板が、その分割された断熱背板間に挟み込まれた状態で配設されているので、たとえ外箱の背板に「反り」が生じて、断熱背板が前後方向に変形や位置ズレを起こしても、その変形や位置ズレが断熱背板の厚みの範囲内であれば、断熱背板と断熱仕切り板との間に従来のような顕著な隙間が生じるおそれはない。
したがって、従来のような特殊なパッキンや固定金具などを必要とせず、また、断熱背板と断熱仕切り板との取り付けも、左右に位置する断熱背板間に断熱仕切り板の端部を挟み込ませるだけの簡単な作業で済み、それでいて各商品収納室における密封性を良好に確保することができる。
【０００７】
請求項２の発明の特徴構成は、前記断熱仕切り板が、その断熱仕切り板挿入用の開口部とその開口部に沿って左右に延出するフランジを備えた背板用ガスケットを介して前記断熱背板間に挟み込まれているところにある。
【０００８】
請求項２の発明の特徴構成によれば、断熱仕切り板が、その断熱仕切り板挿入用の開口部を備えた背板用ガスケットを介して断熱背板間に挟み込まれているので、背板用ガスケットの介在によって、左右に位置する断熱背板間への断熱仕切り板の挿入が極めて容易で確実となる。
しかも、背板用ガスケットが、断熱仕切り板挿入用の開口部に沿って左右に延出するフランジを備えているので、それらフランジが、左右に位置する断熱背板の端部を覆い隠すことになり、たとえ断熱背板の端部と背板用ガスケットとの間に隙間があっても外側から見えることはなく、外観的に美麗であるとともに、その背板用ガスケットを断熱効果に優れた材料で構成する場合には、背板用ガスケットによる断熱作用も期待できる。
【０００９】
請求項３の発明の特徴構成は、前記商品収納庫の底面に配設される断熱底板が、前記複数の商品収納室に対応して複数に分割され、前記断熱仕切り板が、その分割された断熱底板間に挟み込まれた状態で配設されているところにある。
【００１０】
請求項３の発明の特徴構成によれば、商品収納庫の底面に配設される断熱底板が、複数の商品収納室に対応して複数に分割され、断熱仕切り板が、その分割された断熱底板間に挟み込まれた状態で配設されているので、たとえ外箱の収納庫底板に「反り」が生じて、断熱底板が上下方向に変形や位置ズレを起こしても、断熱底板の厚みの範囲内であれば、断熱底板と断熱仕切り板との間に顕著な隙間が生じるおそれはない。
したがって、断熱底板と断熱仕切り板との間にも特殊なパッキンや固定金具などを必要とせず、また、その取り付けも、左右に位置する断熱底板間に断熱仕切り板の端部を挟み込ませるだけの簡単な作業で済み、各商品収納室における密封性をより一層確実に確保することができる。
【００１１】
請求項４の発明の特徴構成は、前記断熱仕切り板が、その断熱仕切り板挿入用の開口部とその開口部に沿って左右に延出するフランジを備えた底板用ガスケットを介して前記断熱底板間に挟み込まれているところにある。
【００１２】
請求項４の発明の特徴構成によれば、断熱仕切り板が、その断熱仕切り板挿入用の開口部を備えた底板用ガスケットを介して断熱底板間に挟み込まれているので、底板用ガスケットの介在によって、左右に位置する断熱底板間への断熱仕切り板の挿入が極めて容易で確実となる。
そして、その底板用ガスケットが、断熱仕切り板挿入用の開口部に沿って左右に延出するフランジを備えているので、それらフランジが、左右に位置する断熱底板の端部を覆い隠し、たとえ断熱底板の端部と底板用ガスケットとの間に隙間があっても外側から見えずに外観的に美麗であり、さらに、背板用ガスケットを断熱効果に優れた材料で構成する場合には、底板用ガスケットによる断熱作用も期待できる。
【００１３】
請求項５の発明の特徴構成は、前面に開閉自在な扉を有する商品収納庫が、板金製の外箱とその外箱の内面に沿って配設された断熱板により構成され、かつ、上下方向に沿う断熱仕切り板によって前面が開口する複数の商品収納室に区画されている構成において、前記外箱の背面を形成する背板と、前記商品収納庫に配設される断熱仕切り板との間には、背板に固着された係止受け部材に対して、背板と断熱仕切り板との間に介在する弾性手段の弾性変形により、断熱仕切り板の側板に固着された係止部材を係合可能な歪矯正手段が設けられている。
【００１４】
請求項５の発明の特徴構成によれば、弾性手段を弾性変形して背板に固着された係止受け部材に対して、断熱仕切り板の係止部材を係合して、外箱の背板と断熱仕切り板とを一体的な連結状態にすることによって、外箱の背板に「反り」が生じることが抑えられることになる。ここで、弾性手段を弾性変形するとは、弾性変形部材を弾性力に抗して押圧しての圧縮変形、圧縮変形する弾性変形部材の押圧を解除して元の状態に復元変形を意味する。
したがって、弾性手段を弾性変形する簡単な組付け作業を実施するだけで、係止受け部材に対して、簡単に係止部材を係合することができ、従来のように背板側のチャンネル材に断熱仕切り板側の固定金具を複数のビス止めなどによって作業手間をかけて連結していたものに比べて、部品点数の増加を抑制し、かつ、取り付け作業の簡素化を図りながら、各商品収納室における密封性を確保できる。
【００１５】
請求項６の発明の特徴構成は、前記弾性手段が、少なくとも断熱仕切り板の後端縁に装着された弾性素材からなる弾性変形部材から構成されている。
【００１６】
請求項６の発明の特徴構成によれば、例えば、前記商品収納庫内で断熱仕切り板を外箱の背板側に押付けて、弾性変形部材を弾性力に抗して圧縮変形することで背板に固着された係止受け部材に対して、断熱仕切り板の係止部材を係入し、続いて、背板側に押付けを解除して復元変形を作用させて再び元の状態に戻して、係止受け部材に対して、断熱仕切り板の係止部材を係合することにより、外箱の背板と断熱仕切り板とを一体的な連結状態にすることができる。
したがって、断熱仕切り板を背板側に押付けることに続いて、断熱仕切り板の押付けを解除するといった簡単な連続作業によって、係止受け部材に対して、断熱仕切り板の係止部材を係合することができるので、作業性や組立性が良く製作性の向上を図ることができる。
【００１７】
請求項７の発明の特徴構成は、前記弾性手段が、断熱仕切り板の後端に当接配備された背板側の弾性素材からなる断熱板から構成されている。
【００１８】
請求項７の発明の特徴構成によれば、例えば、前記商品収納庫内で断熱仕切り板を外箱の背板側に押付けて、背板側の断熱板を弾性復元力に抗して圧縮変形することで背板に固着された係止受け部材に対して、断熱仕切り板の係止部材を係入するか、又は、係止受け部材を冶具を用いて商品収納庫の開口側に引張り、背板側の断熱板を弾性復元力に抗して圧縮変形することで背板に固着された係止受け部材に対して、断熱仕切り板の係止部材を係入し、続いて、背板側への押付けを解除して復元変形を作用させて再び元の状態に戻して、係止受け部材に対して、断熱仕切り板の係止部材を係合することにより、外箱の背板と断熱仕切り板とを一体的な連結状態にすることができる。
したがって、断熱仕切り板を背板側の断熱板に押付けるか、又は、外箱の背板を背板側の断熱板に押付けることに続いて、このような押付けを解除するといった簡単な連続作業によって、係止受け部材に対して、断熱仕切り板の係止部材を係合することができるので、作業性や組立性が良く製作性の向上を図ることができる。
【００１９】
【発明の実施の形態】
〔第１実施形態〕
本発明による自動販売機の断熱構造につき、その実施の形態を図面に基づいて説明する。
自動販売機は、図１および図２に示すように、前面が開口する板金製の外箱からなるキャビネット１を備え、そのキャビネット１の前面開口部は、キャビネット１に回動自在に取り付けられた前面扉２により開閉自在に構成されている。
【００２０】
キャビネット１の内側には、発泡スチロールやウレタンフォームなどの断熱材からなる断熱板３〜６が配設され、具体的には、背面側に位置する断熱背板３、底面側に位置する断熱底板４、左右の側面側に位置する断熱側板５、天井面に位置する断熱天板６が配設されて商品収納庫７が形成されている。
【００２１】
このキャビネット１と断熱板３〜６により構成される商品収納庫７は、発泡スチロールやウレタンフォームなどの断熱材からなる上下方向に沿う断熱仕切り板８によって、前面が開口する２つの商品収納室７ａ，７ｂに区画されて、各商品収納室７ａ，７ｂには、缶入りや壜入り飲料などの商品を収納するサーペンタイン式の商品コラム９と、商品コラム９から払い出した商品を前面扉２に設けた商品取り出し口１０に向けて滑降させるシュート１１が設けられている。そのシュート１１下方の庫内には、庫内を設定温度に保つ冷却装置の室内機１２ａが、庫外には室外機１２ｂが収納配置され、図２において矢印で示すように、シュート１１に穿設の通気孔を介して冷風が送り込まれて各商品収納室７ａ，７ｂ内を循環するように構成されている。
【００２２】
そして、商品収納庫７の前面には、前面扉２の内側に位置する状態で、発泡スチロールやウレタンフォームなどの断熱材からなる内扉１３が配設され、その内扉１３は、上部内扉１３ａと下部内扉１３ｂに分割され、上部内扉１３ａは前面扉２に対して、下部内扉１３ｂはキャビネット１に対して、それぞれ回動自在に取り付けられている。
【００２３】
キャビネット１は、図３に示すように、金属製の板材からなる背板１４、底板１５、左右の側板１６、天板１７などにより矩形の箱状に構成され、底板１５の上方には、商品収納庫７の底板となる収納庫底板１８が取り付けられていて、この収納庫底板１８、背板１４、側板１６、天板１７などにより商品収納庫７の外枠が形成されている。
【００２４】
収納庫底板１８の前端部は、上方に向けてＬ字状に折曲されていて、その折曲部１８ａのうち、左右の商品収納室７ａ，７ｂの区画相当箇所には、切欠き１８ｂが設けられ、さらに、室内機１２ａからのドレンの排出などに利用する左右一対の開口１９ａ，１９ｂも設けられている。
【００２５】
商品収納庫７の外枠の内側に配設される断熱背板３、断熱底板４、左右の断熱側板５、および、断熱天板６のうち、断熱背板３と断熱底板４は、図３〜図５に示すように、それぞれ左右に分割されていて、断熱背板３は、左側断熱背板３ａと右側断熱背板３ｂにより、断熱底板４は、左側断熱底板４ａと右側断熱底板４ｂにより構成され、両断熱底板４ａ，４ｂには、収納庫底板１８の開口１９ａ，１９ｂに対応するように、それぞれ開口２０ａ，開口２０ｂが設けられている。
【００２６】
そして、各断熱背板３ａ，３ｂ、断熱底板４ａ，４ｂ、断熱側板５、および、断熱天板６は、ポリエチレンテレフタレート（ＰＥＴ）などの樹脂シート２１により全面が覆われている。
【００２７】
これら断熱板３ａ，３ｂ，４ａ，４ｂ，５，６のうち、断熱背板３ａ，３ｂ、断熱側板５、および、断熱天板６は、各表面が庫内側に直接露出する状態で取り付けられ、残りの断熱底板４ａ，４ｂについては、キャビネット１の収納庫底板１８上に載置され、かつ、その上面が補強用底板２２ａ，２２ｂにより覆われて取り付けられる。
【００２８】
各補強用底板２２ａ，２２ｂは、金属製の板材により形成されていて、その背面側には、冷風循環用のダクト（図２参照）を形成する断面コの字状のダクト形成部材２３ａ，２３ｂがそれぞれ一体的に形成され、さらに、収納庫底板１８の開口１９ａ，１９ｂと左右断熱底板４ａ，４ｂの開口２０ａ，２０ｂに対応する開口２４ａ，２４ｂが、各補強用底板２２ａ，２２ｂに設けられている。
【００２９】
断熱仕切り板８は、左右の断熱背板３ａ，３ｂと断熱底板４ａ，４ｂとの間にわたって挟み込まれて、商品収納庫７を左右の商品収納室７ａ，７ｂに区画する大きさに設定され、断熱背板３ａ，３ｂなどと同様に、ポリエチレンテレフタレートなどの樹脂シート２１で覆われ、断熱仕切り板８の前端縁には、内扉１３との間を密封する扉密封用ガスケット２５が取り付けられている。
【００３０】
扉密封用ガスケット２５は、例えば、軟質塩化ビニルなどで形成されていて、図５に示すように、ポリプロピレン（ＰＰ）あるいは硬質塩化ビニルからなる断面コの字状の固定具２６と共に押出し成形により一体的に形成され、その固定具２６を介して断熱仕切り板８の前端縁に取り付けられている。
【００３１】
なお、図示はしないが、断熱底板４ａ，４ｂ、断熱側板５、および、断熱天板６の前端縁にも、同様な扉密封用ガスケット２５が取り付けられる。
【００３２】
左右の断熱背板３ａ，３ｂ、断熱側板５、および、断熱天板６は、商品収納庫７の外枠となるキャビネット１の内側に設けられた係止片（図示せず）などへの係止によってキャビネット１の背板１４、側板１６、および、天板１７に沿って取り付けられ、断熱底板４ａ，４ｂは、収納庫底板１８上に載置され、その上面に補強用底板２２ａ，２２ｂが載置されている。
【００３３】
各補強用底板２２ａ，２２ｂは、ビスなどにより収納庫底板１８に連結固定され、それによって収納庫底板１８が補強されて、冷却装置の室内機１２ａやシュート１１などを保持するのに十分な構造体となるように構成されている。
【００３４】
断熱仕切り板８は、左右の断熱背板３ａ，３ｂと断熱底板４ａ，４ｂ間に挟み込まれて取り付けられ、そのため、左右の断熱背板３ａ，３ｂ間には、断熱仕切り板８を挟み込むための背板用ガスケット２７が配設されている。
【００３５】
背板用ガスケット２７は、図６にも示すように、その長手方向に沿って、断熱仕切り板８を挿入するための断面コの字状の開口部２８を備え、かつ、その開口部２８に沿って左右に延出する一対のフランジ２９を備えている。さらに、開口部２８を形成する左右の側壁板２８ａと底壁板２８ｂのうち、左右の側壁板２８ａの内側には、弾性変形可能なヒレ部材３０も設けられ、例えば、ヒレ部材３０が軟質塩化ビニルなどで形成され、その他がポリプロピレンあるいは硬質塩化ビニルで形成されて、全体が押出し成形により一体的に形成されている。
【００３６】
左右の断熱底板４ａ，４ｂ間にも、断熱仕切り板８を挟み込むための底板用ガスケット３１が配設され、この底板用ガスケット３１は、上述した背板用ガスケット２７において、底壁板２８ｂをなくしたような構成とされている。
【００３７】
すなわち、底板用ガスケット３１は、図７にも示すように、左右一対のガスケット対３１ａ，３１ｂにより構成され、各ガスケット対３１ａ，３１ｂは、断熱仕切り板８を挿入するための開口部３２を形成する側壁板３２ａとフランジ３３を備え、さらに、側壁板３２ａに弾性変形可能なヒレ部材３４を備え、背板用ガスケット２７と同じように、例えば、ヒレ部材３４が軟質塩化ビニルなどで、その他がポリプロピレンあるいは硬質塩化ビニルで形成されて、全体が押出し成形により一体的に形成されている。
【００３８】
このようにして、断熱仕切り板８の背板側端部は、背板用ガスケット２７を介して左右の断熱背板３ａ，３ｂ間に挟み込まれているので、たとえキャビネット１の背板１４に「反り」が生じて、断熱背板３ａ，３ｂが前後方向に変形や位置ズレを起こしても、断熱背板３ａ，３ｂと断熱仕切り板８との間に隙間が生じることはない。
【００３９】
同様に、断熱仕切り板８の底板側端部は、底板用ガスケット３１を介して左右の断熱底板４ａ，４ｂ間に挟み込まれているので、収納庫底板１８の「反り」に伴って断熱底板４ａ，４ｂが位置ズレなどを起こしても、断熱底板４ａ，４ｂと断熱仕切り板８との間に隙間が生じることはない。
【００４０】
〔第２実施形態〕
この第２実施形態は、上記第１実施形態と異なる構成を説明し、第１実施形態と同様構成部分には同符号を付してその説明を省略する。
また、上記実施形態では、断熱仕切り板８によって、前面が開口する２つの商品収納室７ａ，７ｂに区画されている商品収納庫７が形成された自動販売機について説明したが、第２実施形態では、２枚の断熱仕切り板８、８によって、前面が開口する３つの商品収納室７ａ，７ｂ，７ｃに区画されている商品収納庫７が形成された自動販売機を図８〜図１２の図面に基づいて説明する。
【００４１】
この実施形態の自動販売機において、図９、図１０に示すように、商品収納庫７の外箱であるキャビネット１の内側に配設される断熱背板３、断熱底板４、左右の断熱側板５、および、断熱天板６は、各板に対応する夫々１枚の断熱板３，４，５，６から形成され、各断熱板３，４，５，６は、ポリエチレンテレフタレート（ＰＥＴ）などの樹脂シート２１により全面が覆われている。
【００４２】
これら断熱板３，４，５，６のうち、断熱背板３、断熱側板５、および、断熱天板６は、各表面が庫内側に直接露出する状態で取り付けられ、残りの断熱底板４については、キャビネット１の収納庫底板１８上に載置され、かつ、その上面が補強用底板２２により覆われて取り付けられる。
【００４３】
各断熱仕切り板８は、商品収納庫７を左右の商品収納室７ａ，７ｂ、７ｃに区画する大きさに設定され、断熱背板３などとは異なり、少なくとも両側面板８ａ，８ａが薄肉な鋼板で覆われ、前端縁には、内扉１３との間を密封する扉密封用ガスケット２５が取り付けられ、後端縁と上端縁に対応して、断熱背板３との間、及び、断熱天板６との間で圧縮変形する弾性素材からなる弾性変形部材であるスポンジ部材３５Ａ，３５Ｂが取り付けられており、商品収納庫７を左右に３つの商品収納室７ａ，７ｂ，７ｃに区画する位置上に、開口側から奥側にスポンジ部材３５Ａ，３５Ｂの弾性付勢力に抗して差し入れることによって、商品収納庫７に各断熱仕切り板８を組み込むことができるようになっている。
【００４４】
前記キャビネット１の背面を形成する背板１４と、前記商品収納庫７に配設される断熱仕切り板８との間には、図８、図１１、図１２に示すように、背板１４に固着された係止受け部材３７に対して、背板１４と断熱仕切り板８との間に配置された弾性手段３８である後端側スポンジ部材３５Ａを弾性変形することにより、断熱仕切り板８の片面の側面板８ａに固着された係止部材３９を係合可能にする歪矯正手段４１が設けられている。弾性手段３８は、断熱仕切り板８を後方に押付けることによって、強制的に後端側スポンジ部材３５Ａを圧縮変形する状態にするとともに、押付けを解除することによって、弾性復帰状態に戻る。
【００４５】
断熱仕切り板８側の係止部材３９は、軸部３９ａの先端に半球形状の係止部３９ｂを形成する杆状体から形成され、この実施形態においては、丸ネジを断熱仕切り板８の側面板８ａにネジ止めして構成されている。
【００４６】
これに対して、背板１４側の係止受け部材３７は、金属製の板材を折り曲げて形成され、基端板部３７ａがキャビネット１の背板１４に固着され、先端板部３７ｂが断熱背板３に形成された孔３ａから商品収納庫７内側に突抜き状態で配置されている。
そして、この先端部３７ｂには、内径が異なる大小の孔が前後に連接する異形孔状の受け孔３７ｃが形成されている。
【００４７】
また、前記断熱背板３の孔３ａには、図８に示すように、孔形状に対応する円柱形状で、孔３ａを貫通する係止受け部材３７の中間部分を挿通可能なスリット３ｂが形成された綴じ栓３Ａが嵌め込まれて、商品収納庫７内の熱が庫外に逃げにくくなる工夫がなされている。
【００４８】
商品収納庫７に組み込まれた断熱仕切り板８は、図１１に示すように、後端側スポンジ材３５Ａが圧縮変形する状態になるように背板１４側に押し込みながら、係止部材３９の係止部３９ａが背板１４側の係止受け部材３７の先端板部３７ｂの受け孔３７ｃの大径孔に対応位置させて挿入し、続いて、断熱仕切り板８の押し込みを解除することにより、弾性変形部材３５を圧縮変形する状態から元の状態に復元変形させて、断熱仕切り板８を商品収納庫７の開口側に押戻すことにより、図１２、図１３に示すように、大径孔側から小径孔に係止部材３９の係止板部３９ｂを係合して、断熱仕切り板８側の係止部材３９を背板１４側の係止受け部材３７に係合状態にすることができる。この係合状態で、断熱仕切り板８は、商品収納庫７に対して拘束された装着状態となる。
【００４９】
この実施形態の係止受け部材３７は、図８に示すように、長方形状の基端板部３７ａの両端の夫々に同方向配置に形成され、商品収納庫７に組み込まれる２枚の断熱仕切り板８，８の係止部材３９に係合可能になっており、一つの部品に２つの係止受け部材３７が形成されると言うように一部品化が図られており、部品点数の増加の抑制などを可能にする構成になっている。ここで、第１実施形態のように、商品収納庫７内を１枚の断熱仕切り板８によって区画する場合は、一部品が一つの係止受け部材であるものを用いるのが合理的である。
【００５０】
このようにして、弾性変形部材３５を弾性変形して背板１４に固着された係止受け部材３７に対して、断熱仕切り板８の係止部材３９を係合することによって、キャビネット１の背板１４と断熱仕切り板８とを一体的な連結状態にすることによって、キャビネット１の背板１４に「反り」が生じることが抑えられることになる。
【００５１】
また、商品収納庫７に対して断熱仕切り板８は、商品収納庫７の開口側から奥側にスポンジ部材３５Ａ，３５Ｂの弾性付勢力に抗して差し入れることによって、商品収納庫７に各断熱仕切り板８を簡単に組み込むことができるようになっているので、例えば、金属製の板からなる断熱仕切り板８側の係止部材と、金属製の板からなる背板側の係止受け部材の重なり部分をネジ止めして両者を連結する構造で、部品点数があり、組付け構造にネジ止めなどの構造で、しかも、作業個所が商品収納庫の奥方で作業性の悪い組付け構造のものに比べて、製作コストの低減化、組立て作業性の迅速化、組立て時間の短縮化などの製作性の向上を図ることができる。
【００５２】

That is, in the related art, the heat insulating back plate 3 provided on the back of the product storage 7 is formed of a single plate-like body, and is attached along the back plate 14 of the outer box 1. The heat insulating bottom plate 4 disposed on the bottom surface of the outer case 1 is also formed of a single plate-like body and attached along the storage bottom plate 18 of the outer box 1. The end surface of the heat insulating partition plate 8 was attached to the surface by abutting.

When the “warp” occurs in the back plate 14, the heat insulating back plate 3 is deformed or misaligned in the front-rear direction, and the heat insulating back plate 3 and the end surface of the heat insulating partition plate 8 are moved as shown in FIG. There is a possibility that a gap S is formed between the product storage rooms and the sealing performance in each product storage room is hindered.
Therefore, in order to fill the gap S between the heat insulating back plate 3 and the end surface of the heat insulating partition plate 8, a packing is specially attached or, as shown in FIG. 17, fixed to the back plate 14 of the outer box 1 by spot welding or the like. A stepped channel member 42 formed from a sheet metal part, a horizontal L-shaped fixture 43 made of a metal plate fixed to the rear edge of the heat insulating partition plate 8 is fixed by a plurality of screws. It is a fact that measures such that a gap S is not generated between the heat insulating back plate 3 and the end surface of the heat insulating partition plate 8 by, for example, integrally connecting the heat insulating back plate 3 and the heat insulating bottom plate 4 and the heat insulating bottom plate 4 in some cases. It is necessary to take the same countermeasures even with the partition plate 8.
Therefore, according to the above-described conventional structure, the packing, the channel member 42, the fixing bracket 43, and the like are required, and the number of components is increased. In addition, the packing, the channel member 42, and the fixing bracket 43 need to be attached. As a result, there is a possibility that the cost may be increased.
