【発明の属する技術分野】
本発明は、貯蔵室内に棚を備えた冷蔵庫に関するものである。
【０００２】
【従来の技術】
近年の冷蔵庫においては、様々な大きさの食品を収納させることにより商品価値向上をねらっている。そのため、回動式の伸縮自在棚を持ったものが多い。
【０００３】
以下、図面を参照しながら上記従来の冷蔵庫を説明する。
【０００４】
図６は、従来の冷蔵庫の貯蔵室内の断面図であり、図７は、同冷蔵庫の伸縮自在棚部分の前棚を前方へ引出した状態の断面図、図８は、同冷蔵庫の伸縮自在棚部分の前棚を後方へ押し込んだ状態の断面図、図９は、同冷蔵庫の伸縮自在棚部分の前棚を後方へ押し込んだ状態の断面図、図１０は、同冷蔵庫の伸縮自在棚の前棚の裏面図、図１１は、同冷蔵庫の伸縮自在棚の前棚の正面図である。
【０００５】
図６から図１１において、伸縮自在棚１は前棚２及び後棚３から成り、後棚３には回転軸４があり、５は貯蔵室の内箱であり、棚を支えるレール６、軸受け部７を備えている。また、前棚２には、引掛け爪８があり、レール６には、切欠き９がある。１０は、伸縮自在棚１の下の棚であり、１１はリブである。
【０００６】
以上のように構成された冷蔵庫について、以下その動作を説明する。
【０００７】
伸縮自在棚１は、レール６上に設置されており、回転軸４は、軸受け部７上にある。前棚２を前方へ引出して使えば、前棚２及び後棚３上に食品を載置できる。また、前棚２を後方へ押し込み後棚３内へ収納すれば、後棚３上のみ食品を載置できるが、棚１０上に前棚２のあった部分に背の高い食品を載置できる。さらに、前棚２を後棚３内に収納した状態で、回転軸４を中心にして伸縮自在棚１を回動させ後方へ立てかけてやれば、棚１０上に前棚２及び後棚３のあった部分に背の高い食品を載置できる。ここで、引掛け爪８は、レール６の下部に位置させ前棚の浮き上がりを防止する。また、前棚２を後棚３内に収納した状態で、回転軸４を中心にして伸縮自在棚１を回転させる場合は、引掛け爪８は、レール６の切欠き９を通過することにより回転することができる。（例えば、特許文献１参照）。

【０００９】
【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、前棚２を後棚３内に収納した状態で使用する際、引掛け爪８が、切欠き９の位置と合致しているためレール６に引掛け爪８が掛からず後棚３上に食品を載置すれば伸縮自在棚１が食品の重量により後方へ回転しようとするといった不安定な状態になるという欠点があった。
【００１０】
本発明は、従来の課題を解決するもので、前棚２を後棚３内に収納した状態で使用する際において伸縮自在棚を安定した状態で使用できる冷蔵庫を提供することを目的とする。
【００１１】
【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、貯蔵室内に食品等を載置するように設けられた前棚と後棚からなり前記前棚は前後方向へ摺動可能で、前記前棚を後ろへ摺動させ前記後棚の下部に収納し、後棚に設けた回転軸を中心に回動させることが可能な伸縮自在棚を有したものにおいて、前記前棚を後棚の下部の第１の位置に収納したとき、前記前棚と内箱に設けた前記前棚および後棚を支えるレール部との係合により前記前棚および後棚の回動を防止し、さらに前棚を後方の第２の位置に移動させると前記前棚と前記レール部との係合が解除され、後棚に設けた回転軸を中心に前記前棚および後棚を回動可能としたものであり、前棚を前記後棚内に収納し、後棚に食品を載置して使用する際、後棚の回動を防止しているので食品の転倒、落下が生じず、安定した状態で使用できる。
【００１２】
請求項２に記載の発明は、貯蔵室内に食品等を載置するように設けられた前棚と後棚からなり前記前棚は前後方向へ摺動可能で、前記前棚を後ろへ摺動させ前記後棚の下部に収納し、後棚に設けた回転軸を中心に回動させることが可能な伸縮自在棚を有したものにおいて、内箱に設けた前記前棚および後棚を支えるレール部に突起部と切欠き部を備え、前記前棚には前記レール下部に位置する引掛け爪及び、前部にはリブを設け、前棚を後方の後棚の下部へ収納時、前記リブと突起部が当接した状態で前記引掛け爪は前記レール部下方に位置し前記前棚および後棚の回動を防止し、さらに前棚を後方へ移動させ前記リブが突起部を乗り越えた状態で前記引掛け爪は切欠き部に位置し、後棚に設けた回転軸を中心に前記前棚および後棚を回動させることが可能としたものであり、前棚を前記後棚内に収納して使用する際、前記前棚を後方へ摺動させると前記前棚に設けた前記リブが前記突起部に当たり、その位置で使用すれば前記引掛け爪が前記レール部に掛かっているため前棚の浮き上がり及び回動しようとするのを防止でき前記後棚に食品を載置しても安定した状態で使用できる。また、前記前棚を前記突起部を乗り越えさらに押し込めば、前記引掛け爪と前記切欠き部の位置が合致し、前記引掛け爪は前記レール部の切欠き部を通過することにより、伸縮自在棚を後方へ回動できる。
【００１３】
請求項３に記載の発明は、請求項２に記載の発明において、内箱に設けた棚を支えるレール部に設ける突起部は前記内箱と一体に成形するものであり、低コスト化と確実な位置決めが可能となる。
【００１４】
請求項４に記載の発明は、請求項２に記載の発明において、内箱に設けた棚を支えるレール部に設ける突起部は前記内箱とは別体で設けたものであり、内箱の成形性を向上できる。
【００１５】
請求項５に記載の発明は、請求項４に記載の発明において、別体の突起部はゴム系の材料としたものであり、前棚のリブと接触するときの音を低減できる。
【００１６】
請求項６に記載の発明は、請求項２から請求項５のいずれか一項に記載の発明において、レール部に設けた突起部の高さ寸法と、引掛け爪とレール部下辺との隙間寸法を略同一としたものであり、前棚を後方の後棚へ収納時、前記リブと突起部が当設した状態で後棚の上下方向のガタツキを最小限に抑えることができる。また、前棚をさらに後方へ移動させ前記リブが突起部を乗り越えた状態への摺動をスムーズに行なうことができる。
【００１７】
請求項７に記載の発明は、請求項２から請求項６のいずれか一項に記載の発明において、前棚の前部に設けたリブは突起部と面当たりするように平面部を設けたものであり、前棚の接触により突起部が傷ついたり変形するのを防止することができる。
【００１８】
【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。なお、従来と同一構成については、同一符号を付して詳細な説明を省略する。
【００１９】
（実施の形態１）
図１は本発明の実施の形態１による冷蔵庫の伸縮自在棚部分の前棚を前方へ引出した状態の断面図、図２は同実施の形態の冷蔵庫の前棚を後方へ押し込んだ状態の断面図、図３は同実施の形態の冷蔵庫の前棚の裏面図、図４は同実施の形態の冷蔵庫の前棚を後方へ押し込んだ状態の要部断面図である。
【００２０】
図１から図４において、樹脂成形品からなる伸縮自在棚２１は前棚２２及び後棚３から成り、後棚３には回転軸４を有している。５は貯蔵室の内箱であり樹脂を真空成形したもので、内箱５の両側面には棚を支えるレール部２３、軸受け部７を備えている。また、レール部２３には、切欠き部９及び、レール部２３と一体に成形された突起部２４があり、前棚２２には、レール部２３の下方に位置し、レール部２３との係合により前記前２２棚および後棚３の回動を防止するために設けた引掛け爪８と、前棚２２の前部のリブ１１には突起部２４と面当たりするように平面部２５を備えている。
【００２１】
また、前棚２２を後方の後棚３の下部の第１の位置に収納したとき、前記リブ１１と突起部２４が当接した状態で前記引掛け爪８は前記レール部２３の下方に位置し後棚３の回動を防止し、さらに前棚２２を後方へ移動させ第２の位置とした時、前記リブ１１が突起部２４を乗り越えた状態で前記引掛け爪８は切欠き部９に位置し、前記前棚と前記レール部との係合が解除され、後棚３に設けた回転軸４を中心に回動可能となっている。
【００２２】
また、図４に示すように、レール部２３に設けた突起部２４の高さ寸法Ａと、引掛け爪８とレール部２３の下辺との隙間寸法Ｂを略同一に設定している。
【００２３】
なお、隙間寸法Ｂを突起部２４の高さ寸法Ａより若干大きくすることが望ましい。
【００２４】
以上のように構成された冷蔵庫について、以下その動作を説明する。
【００２５】
まず、伸縮自在棚２１の前棚２２を前方へ引出した状態で使用すれば、前棚２２及び、後棚３上に食品を載置することができる。次に、前棚２２を後方へ押し込めば、前棚２２は、レール部２３上を摺動し平面部２５が突起部２４に接触する第１の位置に到達した時点で前棚２２が停止し、後棚３の下部に前棚２２が収納される。この状態で使用すれば、伸縮自在棚２１の奥行半幅である後棚３上に食品を載置することができるとともに、前棚２２の引掛け爪８が、レール部２３に当接するところに位置しているため伸縮自在棚２１が後方へ回動するのを防止することができ安定した状態で使用できる。そして前棚２２をさらに押し込めば、平面部２５が突起部２４を乗越え、引掛け爪８と切欠き部９の位置が合致する第２の位置に前棚２２が移動するので引掛け爪８がレール部２３の切欠き部９を通過し、伸縮自在棚２１を後方へ回動させることができ、全幅に亘って背の高い食品を収納でき、使い勝手が向上する。
【００２６】
また、突起部２４を内箱５と一体に成形することにより、切欠き部９と突起部２４位置関係、寸法がずれることなく、伸縮自在棚２１の操作性が確実になる。
【００２７】
また、前棚２２の前部のリブ１１には突起部２４と面当たりするように平面部２５を備えているので、突起２４への傷つき、変形を防止することができ、伸縮自在棚２１の操作に不具合が生じない。さらに、前棚２２の前部のリブ１１に平面部２５を設けることにより、前棚２２の摺動時に左右方向のガタツキが生じても、突起部２４への当接が確実となる。
【００２８】
また、レール部２３に設けた突起部２４の高さ寸法Ａと、引掛け爪８とレール部２３の下辺との隙間寸法Ｂを略同一に設定しているので、前棚２２を後方の後棚３へ収納時、前記リブ１１の平面部２５と突起部２４が当接した状態で後棚３の上下方向のガタツキを最小限に抑えることができ、安定感が増す。また、前棚２２をさらに後方へ移動させ前記リブ１１が突起部２４を乗り越える場合の前棚２２の上下動のクリアランスを確保でき、前棚２２の摺動をスムーズに行なうことができる。
【００２９】
なお、前棚２２を第１の位置で固定し、第２の位置で固定解除する具体的な構造については、本実施の形態の具体構造に必ずしも限定されるものでなく、第１の位置で前棚２２とレール部２３とが相互の係合構造によって係止され、第２の位置に移動すれば前棚２２とレール部２３の係合状態が外されて前棚２２が後棚３とともに回動可能となる相互構造の組み合わせであれば、同様の作用効果を得ることができるものである。
【００３０】
（実施の形態２）
図５は、本発明の実施の形態２による冷蔵庫の伸縮自在棚部分の断面図である。なお、実施の形態１と同一構成については省略し、異なる部分のみ説明する。
【００３１】
図５において、２６は、棚を支えるレール部であり、突起部２７は内箱５とは別体の部品として固定され、ゴム系の材料からなるものである。
【００３２】
上記構成において、伸縮自在棚２１の前棚２２を後方へ押し込めば、前棚２２は、レール部２６上を摺動し平面部２５が突起部２７に接触した時点で前棚２２が停止し、後棚３の下部に前棚２２が収納される。この時、突起部２７は、ゴム系の材料であるので、平面部２５との接触時の音を低減することができ、使用者に不快感を与えない。また、突起部２７はゴム系の材料であるので弾性を有することで接触時にリブ１１が破損することもない。また、突起部２７は前記内箱５とは別体で設けることにより内箱５の形状を簡素化でき、内箱５の成形性を向上できる。
【００３３】

It is desirable that the gap dimension B be slightly larger than the height dimension A of the projection 24.
[0024]
The operation of the refrigerator configured as described above will be described below.
[0025]
First, if the front shelf 22 of the telescopic shelf 21 is used in a state of being pulled out forward, food can be placed on the front shelf 22 and the rear shelf 3. Next, when the front shelf 22 is pushed backward, the front shelf 22 slides on the rail portion 23 and stops when the flat portion 25 reaches the first position where the flat portion 25 contacts the protrusion 24. The front shelf 22 is stored in the lower part of the rear shelf 3. If used in this state, food can be placed on the rear shelf 3 which is half the width of the retractable shelf 21 and the hook 8 of the front shelf 22 is located at a position where it comes into contact with the rail portion 23. As a result, the telescopic shelf 21 can be prevented from rotating backward, and can be used in a stable state. When the front shelf 22 is further pushed in, the front surface 22 moves over the projection 24 and the front shelf 22 moves to the second position where the positions of the hooking claws 8 and the notches 9 match, so that the hooking claws 8 are moved. The telescopic shelf 21 can be rotated backward through the notch 9 of the rail 23, and tall food can be stored over the entire width, thereby improving usability.
[0026]
In addition, by forming the protrusion 24 integrally with the inner box 5, the operability of the telescopic shelf 21 is ensured without the positional relationship and the size of the notch 9 and the protrusion 24 being shifted.
[0027]
Further, since the front ribs 11 of the front shelf 22 are provided with the flat portions 25 so as to be in contact with the projections 24, the projections 24 can be prevented from being damaged and deformed. There is no malfunction in operation. Furthermore, by providing the flat portion 25 on the front rib 11 of the front shelf 22, even if the front shelf 22 slides in the left-right direction when the front shelf 22 slides, the contact with the projection 24 is ensured.
[0028]
Further, since the height A of the protrusion 24 provided on the rail 23 and the gap B between the hook 8 and the lower side of the rail 23 are set to be substantially the same, the front shelf 22 is When the ribs 11 are stored in the shelves 3, the backlash in the vertical direction of the rear shelves 3 can be minimized in a state where the flat portions 25 of the ribs 11 and the protruding portions 24 are in contact with each other, thereby increasing the sense of stability. Further, the front shelf 22 can be further moved rearward to secure a clearance for the vertical movement of the front shelf 22 when the rib 11 gets over the projection 24, and the front shelf 22 can slide smoothly.
[0029]
The specific structure of fixing the front shelf 22 at the first position and releasing the fixing at the second position is not necessarily limited to the specific structure of the present embodiment. The front shelf 22 and the rail portion 23 are locked by the mutual engagement structure, and when the front shelf 22 and the rail portion 23 are moved to the second position, the engagement between the front shelf 22 and the rail portion 23 is released, and the front shelf 22 and the rear shelf 3 are moved together. The same operation and effect can be obtained as long as the combination of the mutual structures enables the rotation.
[0030]
(Embodiment 2)
FIG. 5 is a sectional view of a telescopic shelf of a refrigerator according to Embodiment 2 of the present invention. Note that the same components as those in the first embodiment are omitted, and only different portions will be described.
[0031]
In FIG. 5, reference numeral 26 denotes a rail supporting the shelf, and the projection 27 is fixed as a component separate from the inner box 5, and is made of a rubber-based material.
[0032]
In the above configuration, if the front shelf 22 of the telescopic shelf 21 is pushed backward, the front shelf 22 slides on the rail portion 26 and stops when the flat portion 25 contacts the projection 27, The front shelf 22 is stored under the rear shelf 3. At this time, since the protruding portion 27 is made of a rubber-based material, it is possible to reduce a sound when the protruding portion 27 comes into contact with the flat portion 25, and does not give a user discomfort. Further, since the protrusion 27 is made of a rubber material, it has elasticity so that the rib 11 is not damaged at the time of contact. In addition, by providing the protrusion 27 separately from the inner box 5, the shape of the inner box 5 can be simplified, and the moldability of the inner box 5 can be improved.
