Description

【０００１】
【発明の属する技術分野】
本発明は、厨房等の場所で使用する収納部を作業に支障のない上方に配置し、必要に応じて出し入れ自由な下方位置に降下させる昇降動作を行うことができる昇降収納装置に関するものである。
【０００２】
【従来の技術】
収納部を上方位置と下方位置との間に昇降させる方法として、収納部を鉛直線上に直線的に昇降させることが考えられるが、収納部に収納した物品の重量が増したとき、上昇させることが困難になるため、より軽い力で上昇させることができるように、回動により昇降する収納部の昇降装置が提案されている。図９は回動による収納部の昇降装置の従来例を示すもので、リンク機構より収納部を回動させて昇降できるように構成されている。
【０００３】
この昇降装置は、図９に示すように、厨房の流し台ｄ等の作業台の上方に配置したキャビネットｃ内に収容された収納部ａを下方位置との間に昇降できるように構成されている。収納部ａがキャビネットｃ内に収容されている状態では流し台ｄを使用する作業に支障はなく、必要に応じてキャビネットｃの扉を開いて収納部ａを引き下ろすと、自由に出し入れのできる下方位置に降下させることができる。収納部ａはキャビネットｃに回動自在に取り付けられた平行リンクｂの自由端に支持されているので、収納部ａはキャビネットｃ内と手前下方位置とに回動させて昇降動作を行うことができる。
【０００４】
このような厨房だけでなく、上方空間を物品の収納場所としてキャビネット類を配置することがなされるが、物の出し入れに踏み台等を用いないと自由に出し入れができないので、上記のように収納部ａを昇降できるように構成すると上方空間に設けた収納部の有効活用を図ることができる。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記構成では収納部ａはキャビネットｃの手前側が下降位置となるので、収納部ａを下降させた状態では流し台等の作業台での作業ができなくなることや、昇降する高さ距離が小さいためキャビネットｃをあまり高い位置に配置することができない問題点があった。
【０００６】
本発明の目的とするところは、収納部を約１８０度の回動により上方位置とその真下の下方位置との間に昇降させることができる昇降収納装置を提供することにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するための第１発明は、収納部と、収納部を上方の格納位置に収容すると共に収納部の出入り方向面と下面とが開放された収容部と、収納部の１つの支持支点を自由端部に支持して回動支点まわりの回動にて前記格納位置とその真下で且つ収納部が前記収容部の下端から露出する出し入れ位置とに昇降させる支持部材と、この支持部材の回動に連動して収納部を所定の姿勢に規制する姿勢規制手段とを備え、支持部材は１本のアームであり、姿勢規制手段は回動支点と同心で非回転に設けられた固定輪と、収納部の支持支点と同心で収納部と一体に回動する回動輪と、これら固定輪と回動輪とに掛け渡したベルトとにより構成し、収納部の相対向する両側にある支持支点を一対の支持部材により支持し、これら一対の支持部材を同期回動させるように双方を連結する連結軸を備え、この連結軸を収容部内の収納部が出し入れ位置へ向かうのとは反対側の上方隅角部に設け、回動支点まわりに回動自在で支持部材に固定された連動輪とこの連動輪より外径が小さく回動自在とした前記連結軸との間に連動ベルトを掛け渡したことを特徴とする昇降収納装置である。
【０００８】
このように収納部を回動により上方位置からその真下の下方位置に降下できるようにすると昇降距離が大きくなり、上方位置をより高い位置に設定しても下降させれば自由に収納した物品を出し入れすることができる。また、下降させた下方位置が上方位置の真下であると、収納部の前面への突出がなく、下方に作業台等があっても下降させたままの状態で作業に支障をきたすことが少なく、収納部への物品の出し入れを伴う作業を行うこともできる。更に、上方位置からその真下の下方位置への昇降は、直線的な移動でなく回動させることによって行うので、垂直方向への昇降動作に比べ昇降動作、特に上昇方向への移動を楽に行うことができる。
また、支持部材による１点支持の回動であっても、回動支点に固定された固定輪と収納部の支持支点に固定された回動輪との間にベルトが掛け渡されているので、回動輪は姿勢維持ベルトの緊張を受けて収納部の姿勢が傾くことが規制され一定の姿勢が維持される。
さらに、一対の支持部材を連結軸で双方を連結することにより同期回動できるようにすると共に、この連結軸は収容部の上方隅角部に設けることにより収容部内に無駄なスペースを設けることなく配設することができる。
特に、連動輪と連結軸との間に連動ベルトを掛け渡して両側の支持部材を同期して回動させるとき、連結軸の外径が連動輪の外径より小さい関係から減速による回動速度を抑制するトルクが支持部材に加わり収納部の降下時に収納部の重量により急激に降下することが抑えられる。
【００１０】
また、収納部は１つの支持支点を回動する支持部材の自由端部に支持されて回動し、上昇位置の下の下降位置との間に昇降されるが、回動時の収納部の姿勢は姿勢規制手段により所定の姿勢に保たれるので、収納部は一定の姿勢を維持して回動させ昇降させることができる。
【００１１】
更に、収納部を上昇位置で引出し可能に収容し格納する収容部により、昇降機構の支持部とすると共に、この機構部分を含んで収納部を収容することができるので美観上からも機構部分の保護上からも適した構造とすることができる。
【００１３】
特に、上記構成では、収納部は上昇位置では収容部内の格納位置にあり、下降させるときには収容部の開放部から収納部を引き出すことにより支持部材の回動により下降し収容部の真下の引出し位置に収納部の一部を収容部から露出した状態で停止する。収容部は収納部を格納できる高さ寸法に形成しておくことにより、収納部を格納したときの下方空間を大きくとることができ、作業台等の上方に収容部を配置したときにも作業に支障を与えない。収納部を下降させたときには収容部の真下にその下端から露出した状態の出し入れ位置に移動するので、使用しやすい高さとなる。
【００１５】
また、収容部は作業台の上にあり、収納部の下降位置または出し入れ位置は作業台と収容部との間のアイレベルに対応する高さとして構成することができ、収容部から収納部を下降させたとき、その下降位置または引出し位置はアイレベルとなるので、収容した物品の視認や出し入れが容易となり、上昇させた格納位置に収納部を収容したときには作業台での作業に支障を与えない。
【００１８】
更に、支持部材に働く収納部による回動トルクを軽減または相殺する釣り合い手段を設けて構成することができ、収納部を上昇させるのに大きなトルクが必要な場合には、これを軽減させる補助動力機構を設けたり、収納部の降下速度が速くなり過ぎるような場合には、回動を抑制するダンパ等の手段を設けて、収納部内収納した物品の重量にかかわらず安定した昇降動作を行わせることができる。
【００１９】
更に、収納部は電気機器保持台で、これに電気機器接続のためのコンセントを設け、このコンセントへの電源接続が格納位置でオフ、引出し位置でオンとなるように構成することができ、収納部に電気機器を配置すれば、使用時に下降させればコンセントがオンとなって使用することができ、収容部に格納すれば電源オフとなるような使用方法にも採用することができる。
【００２０】
更に、収納部は水切り、水受けを備えた食器配列台で、出し入れ位置において食器を収容し、格納位置に上昇して収容部に設けられた温風発生器により食器を乾燥させる食器乾燥機として構成することができ、流し台の上方に設置して下降させた収納部に洗い上げた食器を並べ、上昇させて収容部内に格納したとき、収容部に設けた温風発生器により食器を乾燥させることができ、調理台等の上を占拠しない食器乾燥機を構成することができる。
【００２１】
更に、支持部材は回動支点から前後方向への回動可能に構成され、格納位置にある収容部を任意方向に回動させて昇降移動させるように構成することができ、対面キッチンのような場所に設置した場合に厨房側とダイニング側とに回動移動させて両方から利用することができる。
【００２２】
【発明の実施の形態】
以下、添付図面を参照して本発明の一実施形態について説明し、本発明の理解に供する。
【００２３】
本発明の昇降収納装置は、収納部を回動により上方位置とそのほぼ真下の下方位置との間に昇降動作させるもので、厨房の流し台や調理台等の上方に配置した場合の実施形態について以下に説明する。
【００２４】
図１は本実施形態に係る昇降収納装置の構成と動作を説明する側面図で、昇降収納装置Ａは、壁面４に沿って配設された調理台６の上方に配設されており、図１（ａ）に示すように、収容部５内に格納された収納部１は、この位置を上昇位置として回動機構２により（ａ）〜（ｅ）の順に示すように、ほぼ１８０度回動して収容部５のほぼ真下の下降位置に回動移動し、逆に下降位置から上昇位置に回動移動して昇降できるように構成されている。
【００２５】
前記収容部５は、前面及び下面開放のキャビネット状に形成され、前面の開放部は扉５ａによって開閉自在に形成されている。収納部１を出し入れするときには扉５ａを開けば前面開放となり、収納部１の出入りは自由であり、収納部１を格納して扉５ａを閉じれば、収納部１が前面開放のラック状に形成されている場合でも収容部５内に隠して美観を損なわず、またホコリ等の侵入も防ぐことができる。
【００２６】
収納部１を上昇位置と下降位置との間に昇降させる回動機構２は、図２に拡大図示するように構成されている。
【００２７】
図２において、回動機構２は、収容部５の両側内壁面の回動支点Ｐに回動自在に支持され、その自由端を収納部１の両側外壁面の支持支点Ｏに回動自在に支持させた支持部材７と、前記回動支点Ｐに同心で非回転に設けられた固定輪８と、前記支持支点Ｏに同心で収納部１と一体に回動する回動輪９と、固定輪８と回動輪９との間に掛け渡した姿勢維持ベルト１１と、前記固定輪８と同心で支持部材７と一体に回動する連動輪１０（図３及び図４参照）と、この連動輪１０と連結軸１３との間に掛け渡された連動ベルト１２とを備えて構成され、更に、この回動機構２は図３の正面図に示すように、左右対称位置に回動機構２_L、２_Rとして一対に設けられ、それぞれの間は前記連結軸１３で連結されて回動機構２_L、２_Rが同期回動できるように構成されている。
【００２８】
収納部１は、図１（ａ）に示す上昇位置から、その最下部の前方に設けられた把手１ａを持って収容部５から引き出しつつ引き下ろせば、支持部材７で支持されて回動するので、ほぼ１８０度の回動で図１（ｅ）に示すように収容部５の真下の下降位置に降下させることができる。この下降位置は調理台６と収容部５との間で、調理台前に立った人のアイレベルに対応する高さに設定すると、収納部１への物品の出し入れ等は容易に行うことができる。また、下降位置において収納部１が収容部５の下端から露出する部分は大きいほど物品の出し入れは容易となるが、露出量を大きくすると回動機構２の一部が外部に露出して外観上で好ましくなく、図１に示すように、収容部５の高さ寸法は、収納部１を把手１ａを下端から露出させた状態で格納できるようにし、支持部材７のアーム長による収納部１の回動半径は、回動時の収納部１の前方への振り出し量を小さく、且つ回動操作を容易にするため、回動支点Ｐ及び支持支点Ｏの位置、支持部材７のアーム長は好ましい状態に設定されている。
【００２９】
図１、図２に示したように、収納部１の支持支点Ｏは収納部１の姿勢が水平に保たれる位置になく、また、収納する物品の重量や収納位置によっても姿勢変動してしまうので、収納部１がどの回動位置にあっても常に一定の姿勢に保つため、回動機構２に姿勢規制手段が設けられている。この姿勢規制手段は、前記固定輪８、回動輪９、姿勢維持ベルト１１により構成されており、この動作を図２、図４を参照して説明する。
【００３０】
図４において、収容部５に設定された回動支点Ｐを軸心として収容部５の内側面に取り付けられた支持軸１４に、支持部材７の一端が回動自在に支持され、固定輪８が支持軸１４と同心に固定されている。一方、収納部１の外側面の支持支点Ｏに固定された回動軸受け１５には、支持部材７の他端に設けられた回動軸７ａが回動自在に支持され、回動輪９が前記回動軸７ａと同心で軸受け１５に固定されている。この回動輪９と前記固定輪８との間には図２に示すように姿勢維持ベルト１１が掛け渡されているので、収納部１は回動輪９が姿勢維持ベルト１１を通じて収容部５に固定された固定輪８に連結されていることから、支持支点Ｏを中心として傾く方向に回動せず、この状態は収納部１を回動支点Ｐまわりに回動させたときにも維持されるので、上昇位置と下降位置との間の回動によっても水平状態が維持される。この姿勢維持手段の構成は、上記のようなプーリ（固定輪８及び回動輪９）とベルト（姿勢維持ベルト１１）との組み合わせでなく、ギアとタイミングベルトまたはチェーン等の組み合わせによっても構成することができる。
【００３１】
上記姿勢維持手段及び支持部材７は、収納部１の両側に一対に設けられているので、これらを同期回動させるため、図４に示すように回動支点Ｐと同心に支持軸１４に回動自在で支持部材７に固定された連動輪１０と、収容部５の対向する両側面間に回動自在に配設された連結軸１３との間に、連動ベルト１２が掛け渡され、両側の支持部材７を同期して回動させている。また、前記連結軸１３の外径は連動輪１０の外径より小さく設定されているので、減速による回動速度を抑制するトルクが支持部材７に加わり収納部１の降下時に収納部１の重量により急激に降下することが抑えられる。更に、連結軸１３または支持部材７にロータリーダンパやバネ等による釣り合い手段を設けて、収納部１が降下するときの回動速度を抑制し、上昇するときの回動トルクを軽減させることによって、降下と上昇との回動トルクの均一化を図ると共に上昇動作を楽に行うようにすることができる。この釣り合い手段は、支持部材７そのものの回動トルクを制御するように、収容部５の両内側面にダンパ等を設けて構成することもできる。また、連結軸１３にモータを連結して、これを収納部１の回動の補助動力としたり、制動を加えるように作用させたり、あるいは電動により昇降動作を行わせることもできる。
【００３２】
前記連結軸１３の配設位置は、図１または図２に示すように、収容部５の後方の上方隅角部が望ましく、その他の位置では収容部５内に無駄なスペースを増やすか、収納部１の高さ寸法を小さくしなければならなくなる。収容部５の後方の上方隅角部は、収容部１が下降位置方向に回動する反対側であり、図１（ａ）に示すように収容部５内のスペースいっぱいに収納部１を無駄なく収容させた場合でも、収納部１の上部後方に連結軸１３を避ける切り欠き部分を形成するだけでよい。この収納部１の上部後方部分は、収納上デッドスペースとなりやすい部分なので、切り欠くことによる収納スペースの減少に大きな影響を与えることはない。
【００３３】
上記構成になる昇降収納装置Ａは、厨房で使用する食器や食品の収納だけでなく、電気機器の収納場所としても利用価値がある。例えば、図５に示すように、収納部１にコンセント１６を設け、このコンセント１６への電源接続を収納部１の下降位置でオン、上昇位置でオフとなるように構成すると、収納部１に収容した電気機器２０は、使用するときには収納部１を下降させ、使用しない状態では上昇位置に格納できるので、調理台６等の上に常時置いておくと邪魔になるものでも有効に利用することができる。
【００３４】
また、図６に示すように、収納部１は水切り棚１７や水受け皿１８等を備えた食器の配列部とし、収容部５に温風発生器１９を設けて構成し、下降位置で洗い上げた食器を収容して上昇位置に回動させると、収容部５に格納した状態で食器の乾燥を行うことができ、狭い調理台６等の上を占拠しない有用な食器乾燥機を構成することもできる。
【００３５】
更に、図７に示すように、収納部１は前面から後面に素通しのラック状に形成すると、対面キッチンのように厨房側とダイニング側との両方から収納部１を利用することができる。この構成は更に発展させて、図８に示すように、収容部５を厨房とダイニングとの間に吊設し、収納部１を厨房側とダイニング側とに回動できるようにすることもでき、両側で使用する用途をより向上させることができる。
【００３６】
以上説明した実施形態は、昇降収納装置Ａを厨房で使用する場合の具体例としたが、その他の場所での使用においても有効に活用させることができる。例えば、事務所などでは設置した複写機、ファクシミリ、コンピュータ等の上方空間を有効利用して、トナーカートリッジ、感熱用紙、記憶ディスク、クリーナ、マニュアル類等、常時は使用しない物品の収納場所を提供することができる。また、工場等の作業スペースでは、工具、測定器、補充部品等の収納場所として利用することができる。
【００３７】
【発明の効果】
以上の説明の通り本願の第１発明によれば、収納部を回動により上方位置からその真下の下方位置に降下できるため、昇降距離が大きくなり、上方位置をより高い位置に設定しても下降させれば自由に収納した物品を出し入れすることができる。また、下降させた下方位置が上方位置の真下であると、収納部の前面への突出がなく、下方に作業台等があっても下降させたままの状態で作業に支障をきたすことが少なく、収納部への物品の出し入れを伴う作業を行うこともできる。
【００３８】
更に、上方位置からその真下の下方位置への昇降は、直線的な移動でなく回動させることによって行うので、垂直方向への昇降操作に比べて昇降動作、特に上昇方向への移動を楽に行うことができる。
【００３９】
また、支持部材による１点支持の回動であっても、回動支点に固定された固定輪と収納部の支持支点に固定された回動輪との間にベルトが掛け渡されているので、回動輪は姿勢維持ベルトの緊張を受けて収納部の姿勢が傾くことが規制され一定の姿勢が維持される。
しかも、一対の支持部材を連結軸で双方を連結することにより同期回動できるようにすると共に、この連結軸は収容部の上方隅角部に設けることにより収容部内に無駄なスペースを設けることなく配設することができる。
特に、連動輪と連結軸との間に連動ベルトを掛け渡して両側の支持部材を同期して回動させるとき、連結軸の外径が連動輪の外径より小さい関係から減速による回動速度を抑制するトルクが支持部材に加わり収納部の降下時に収納部の重量により急激に降下することが抑えられる。

BACKGROUND OF THE INVENTION
The present invention, the housing unit to be used in place of the kitchen or the like is disposed above does not hinder work, relates the temperature descending storage device Ru can be performed lifting operations of lowering the out free lower position as required It is.
[0002]
[Prior art]
As a method of raising and lowering the storage unit between the upper position and the lower position, it is conceivable to raise and lower the storage unit linearly on the vertical line, but when the weight of the article stored in the storage unit increases, it is raised. Therefore, an elevating device for a storage unit that elevates and lowers by rotation has been proposed so that it can be raised with a lighter force. FIG. 9 shows a conventional example of a lifting / lowering device for a storage portion by rotation, and is configured to be lifted / lowered by rotating the storage portion by a link mechanism.
[0003]
As shown in FIG. 9, the lifting device is configured to be able to move up and down between a lower portion and a storage portion a stored in a cabinet c disposed above a work table such as a kitchen sink d. . In the state where the storage part a is stored in the cabinet c, there is no hindrance to the work using the sink d, and if the storage part a is pulled down by opening the door of the cabinet c as needed, it can be freely moved in and out. Can be lowered to a position. Since the storage part a is supported by the free end of the parallel link b rotatably attached to the cabinet c, the storage part a can be moved up and down by rotating in the cabinet c and the front lower position. it can.
[0004]
In addition to such kitchens, cabinets can be placed using the upper space as a place for storing articles, but it is not possible to freely put in and out without using a step board to put in and out things. If it is comprised so that a can be raised / lowered, the effective utilization of the accommodating part provided in upper space can be aimed at.
[0005]
[Problems to be solved by the invention]
However, in the above configuration, the storage unit a is in the lowered position on the front side of the cabinet c. Therefore, when the storage unit a is lowered, the work on the work table such as a sink cannot be performed, and the height distance to be moved up and down is small. Therefore, there is a problem that the cabinet c cannot be arranged at a very high position.
[0006]
It is an object of the present invention is to provide a temperature descending storage device Ru can be raised and lowered between an upper position and a lower position just below the former position by the rotation of about 180 degrees compartment.
[0007]
[Means for Solving the Problems]
A first invention for achieving the above object is to provide a storage unit, a storage unit that stores the storage unit in an upper storage position and that has an open / closed surface and a lower surface thereof, and one support for the storage unit. A support member that supports a fulcrum at a free end and moves up and down to the retracted position and a retracted position where the storage part is exposed from the lower end of the storage part by rotating around the rotation fulcrum, and the support member And a posture restricting means for restricting the storage portion to a predetermined posture in conjunction with the rotation of the support member, the support member is a single arm, and the posture restricting means is concentric with the rotation fulcrum and fixed non-rotatably. The support unit is composed of a ring, a rotating wheel that is concentric with the support fulcrum of the storage unit and rotates integrally with the storage unit, and a belt that spans between the fixed wheel and the rotary wheel, and is supported on opposite sides of the storage unit. The fulcrum is supported by a pair of support members, and the pair of support members It has a connecting shaft that connects the two so as to rotate synchronously, and this connecting shaft is provided at the upper corner on the opposite side of the storage portion in the storage portion toward the loading / unloading position, and can be rotated around the rotation fulcrum. In this lifting and lowering storage device, an interlocking belt is stretched between the interlocking wheel fixed to the support member and the connecting shaft that has a smaller outer diameter and is rotatable .
[0008]
In this way, if the storage part can be lowered from the upper position to the lower position just below it by turning, the lifting distance increases, and even if the upper position is set to a higher position, the articles stored freely can be stored by lowering it. Can be put in and out. Further, when the lowered lower position is directly below the upper position, there is no protrusion to the front surface of the storage portion, and even if there is a work table or the like below, it is less likely to hinder the work in the lowered state. In addition, it is possible to perform an operation involving taking in and out of articles in the storage unit. Furthermore, since the raising / lowering from the upper position to the lower position just below it is not performed by linear movement but by turning, it is easier to move up / down, especially in the up direction, compared to the up / down movement in the vertical direction. Can do.
In addition, even in the case of one-point support rotation by the support member, since the belt is stretched between the fixed wheel fixed to the rotation fulcrum and the rotation wheel fixed to the support fulcrum of the storage unit, The rotating wheel is restrained from tilting the posture of the storage unit under the tension of the posture maintaining belt, and a constant posture is maintained.
Further, the pair of support members can be rotated synchronously by connecting both of them with a connecting shaft, and this connecting shaft is provided at the upper corner of the receiving portion, so that no wasteful space is provided in the receiving portion. It can be arranged.
In particular, when the interlocking belt is spanned between the interlocking wheel and the connecting shaft, and the support members on both sides are rotated synchronously, the rotational speed due to deceleration is reduced because the outer diameter of the connecting shaft is smaller than the outer diameter of the interlocking wheel. A torque that suppresses the movement is applied to the support member, so that a sudden drop due to the weight of the storage portion when the storage portion is lowered can be suppressed.
[0010]
Also, housing section is supported in rotation to the free end of the support member for rotating the one support pivot, but is elevated between the lowered position below the raised position, the housing part at the time of rotation since the posture is maintained at a predetermined posture by the posture regulating means housing portion may Rukoto by lifting pivoted to maintain a constant attitude.
[0011]
Further, the storage portion that can be pulled out and stored in the raised position can be used as a support portion for the lifting mechanism, and the storage portion can be stored including this mechanism portion. A structure suitable for protection can also be obtained.
[0013]
In particular, in the above configuration, the storage portion is in the storage position in the storage portion in the raised position, and when lowered, the storage portion is lowered from the opening portion of the storage portion and is lowered by the rotation of the support member, and is pulled out immediately below the storage portion. In a state where a part of the storage part is exposed from the storage part. By forming the storage unit to a height that can store the storage unit, it is possible to increase the lower space when the storage unit is stored, and work even when the storage unit is arranged above the work table or the like. Will not be disturbed. When the storage unit is lowered, the storage unit moves to a loading / unloading position that is exposed from the lower end thereof directly below the storage unit, so that the height becomes easy to use.
[0015]
In addition, the storage unit is on the workbench, and the lowering position or the loading / unloading position of the storage unit can be configured as a height corresponding to the eye level between the workbench and the storage unit. When lowered, the lowered or pulled out position is at the eye level, so it is easy to visually check and put in and out of the stored items. When the storage unit is stored in the raised storage position, it interferes with work on the work table. Absent.
[0018]
Furthermore, it is possible to provide a balance means for reducing or canceling the rotational torque due to the storage portion acting on the support member, and when a large torque is required to raise the storage portion, auxiliary power for reducing this is provided. If a mechanism is provided or the lowering speed of the storage section becomes too fast, a means such as a damper that suppresses rotation is provided so that a stable lifting operation can be performed regardless of the weight of the articles stored in the storage section. be able to.
[0019]
In addition, the storage unit is an electric equipment holding stand, and an outlet for connecting to the electric equipment is provided, and the power connection to this outlet can be configured to be turned off at the storage position and turned on at the drawer position. If an electric device is arranged in the unit, the outlet can be turned on when the unit is lowered during use, and the power can be turned off when stored in the storage unit.
[0020]
In addition, the storage unit is a tableware table with a drainer and a water tray. The table is a tableware dryer that stores the tableware at the loading / unloading position, and rises to the storage position and dries the tableware by the hot air generator provided in the storage unit. When the tableware washed up is placed in the storage unit that is installed and lowered above the sink, and is raised and stored in the storage unit, the tableware is dried by the hot air generator provided in the storage unit. The tableware dryer which does not occupy the top of a cooking table etc. can be comprised.
[0021]
Further, the support member is configured to be able to rotate in the front-rear direction from the rotation fulcrum, and can be configured to rotate the accommodating portion at the storage position in an arbitrary direction to move up and down, such as a face-to-face kitchen. When installed in a place, it can be rotated from the kitchen side to the dining side and used from both.
[0022]

The accommodating portion 5 is formed in a cabinet shape having an open front surface and a lower surface, and the open portion on the front surface is formed to be freely opened and closed by a door 5a. When the storage unit 1 is put in and out, the front surface is opened when the door 5a is opened, and the storage unit 1 can be freely moved in and out. When the storage unit 1 is stored and the door 5a is closed, the storage unit 1 is formed in a rack shape with the front surface open. Even if it is, it can be hidden in the housing part 5 without losing its aesthetics, and dust and the like can be prevented from entering.
[0026]
A rotating mechanism 2 that raises and lowers the storage unit 1 between a raised position and a lowered position is configured to be enlarged in FIG.
[0027]
In FIG. 2, the rotation mechanism 2 is rotatably supported on the rotation fulcrums P on the inner wall surfaces on both sides of the storage portion 5, and the free ends thereof can be rotated on the support fulcrums O on the outer wall surfaces on both sides of the storage portion 1. A supporting member 7 that is supported, a fixed wheel 8 that is concentrically and non-rotatably provided on the rotation fulcrum P, a rotation wheel 9 that is concentric with the support fulcrum O and that rotates integrally with the storage unit 1, and a fixed wheel. A posture maintaining belt 11 spanned between 8 and the rotating wheel 9, an interlocking wheel 10 (see FIGS. 3 and 4) concentrically with the fixed wheel 8 and rotating integrally with the support member 7, and the interlocking wheel. 10 and is configured with an interlocking belt 12 passed over between the connecting shaft 13, further, the rotation mechanism 2, as shown in the front view of FIG. 3, the rotating mechanism to the right and left symmetrical positions 2 _L 2 _R is provided as a pair, and the rotation mechanism 2 _L , 2 _R can be synchronously rotated by being connected by the connecting shaft 13 between each. It is configured as follows.
[0028]
The storage unit 1 is supported by the support member 7 and rotated from the raised position shown in FIG. 1 (a) by pulling it down while pulling out the storage unit 5 with the handle 1a provided at the lowermost front. Therefore, as shown in FIG. 1 (e), it can be lowered to a lowered position directly below the accommodating portion 5 by turning about 180 degrees. When this lowered position is set between the cooking table 6 and the storage unit 5 at a height corresponding to the eye level of a person standing in front of the cooking table, articles can be easily put in and out of the storage unit 1. it can. Further, the larger the portion where the storage portion 1 is exposed from the lower end of the storage portion 5 in the lowered position, the easier the article can be put in and out. However, when the exposure amount is increased, a part of the rotating mechanism 2 is exposed to the outside and the appearance is increased. As shown in FIG. 1, the height of the storage portion 5 is such that the storage portion 1 can be stored with the handle 1 a exposed from the lower end, and the height of the storage portion 1 is determined by the arm length of the support member 7. For the turning radius, the position of the turning fulcrum P and the supporting fulcrum O and the arm length of the support member 7 are preferable in order to reduce the amount of swinging forward of the storage unit 1 during turning and facilitate the turning operation. Set to state.
[0029]
As shown in FIGS. 1 and 2, the support fulcrum O of the storage unit 1 is not in a position where the posture of the storage unit 1 is kept horizontal, and the posture varies depending on the weight of the article to be stored and the storage position. Therefore, in order to always maintain a fixed posture regardless of the rotation position of the storage unit 1, the rotation mechanism 2 is provided with a posture regulating means. This posture regulating means is constituted by the fixed wheel 8, the rotating wheel 9, and the posture maintaining belt 11, and this operation will be described with reference to FIGS.
[0030]
In FIG. 4, one end of a support member 7 is rotatably supported on a support shaft 14 attached to the inner side surface of the storage portion 5 with a rotation fulcrum P set in the storage portion 5 as an axis. Is fixed concentrically with the support shaft 14. On the other hand, the rotation shaft 15a provided at the other end of the support member 7 is rotatably supported by the rotation bearing 15 fixed to the support fulcrum O on the outer side surface of the storage portion 1, and the rotation wheel 9 is It is fixed to the bearing 15 concentrically with the rotating shaft 7a. As shown in FIG. 2, the posture maintaining belt 11 is stretched between the rotating wheel 9 and the fixed wheel 8, so that the storage unit 1 is fixed to the storage unit 5 through the posture maintaining belt 11. Since it is connected to the fixed wheel 8, it does not rotate in the direction tilting around the support fulcrum O, and this state is maintained even when the storage portion 1 is rotated around the rotation fulcrum P. Therefore, the horizontal state is maintained also by the rotation between the raised position and the lowered position. The configuration of the posture maintaining means is not limited to the combination of the pulley (fixed wheel 8 and rotating wheel 9) and the belt (posture maintaining belt 11) as described above, but is also configured by a combination of a gear and a timing belt or a chain. Can do.
[0031]
Since the posture maintaining means and the support member 7 are provided as a pair on both sides of the storage portion 1, in order to rotate them synchronously, they rotate around the support shaft 14 concentrically with the rotation fulcrum P as shown in FIG. The interlocking belt 12 is stretched between the interlocking wheel 10 that is movable and fixed to the support member 7 and the connecting shaft 13 that is rotatably disposed between the opposite side surfaces of the housing portion 5. These support members 7 are rotated synchronously. Further, since the outer diameter of the connecting shaft 13 is set smaller than the outer diameter of the interlocking wheel 10, a torque that suppresses the rotational speed due to deceleration is applied to the support member 7, and the weight of the storage portion 1 when the storage portion 1 is lowered. It is possible to suppress a sudden drop. Furthermore, the connecting shaft 13 or the support member 7 is provided with balancing means such as a rotary damper or a spring to suppress the rotation speed when the storage unit 1 is lowered and reduce the rotation torque when it is raised, It is possible to make the turning torque uniform between descending and ascending and to easily perform the ascending operation. This balancing means can also be configured by providing dampers or the like on both inner side surfaces of the accommodating portion 5 so as to control the rotational torque of the support member 7 itself. In addition, a motor can be connected to the connecting shaft 13 and used as auxiliary power for turning the storage portion 1, act so as to apply braking, or move up and down electrically.
[0032]
As shown in FIG. 1 or FIG. 2, the arrangement position of the connecting shaft 13 is desirably an upper corner portion at the rear of the accommodating portion 5, and in other positions, a wasteful space is increased or accommodated in the accommodating portion 5. The height dimension of the part 1 must be reduced. The upper corner at the rear of the accommodating portion 5 is the opposite side where the accommodating portion 1 rotates in the lowered position direction, and the accommodating portion 1 is wasted to fill the space in the accommodating portion 5 as shown in FIG. Even when it is accommodated without any problem, it is only necessary to form a notch portion that avoids the connecting shaft 13 at the upper rear of the accommodating portion 1. The upper rear portion of the storage portion 1 is a portion that tends to become a dead space for storage, and thus does not greatly affect the reduction of the storage space due to the cutout.
[0033]
The lifting / lowering storage apparatus A configured as described above is useful not only for storing tableware and food used in a kitchen, but also for storing electrical equipment. For example, as shown in FIG. 5, if the storage unit 1 is provided with an outlet 16 and the power connection to the outlet 16 is configured to be turned on when the storage unit 1 is lowered and turned off when the storage unit 1 is raised, The housed electric device 20 can be stored in the raised position when not in use, and can be stored in the raised position when not in use. Can do.
[0034]
Further, as shown in FIG. 6, the storage unit 1 is an arrangement unit of tableware provided with a draining shelf 17, a water tray 18 and the like, and a hot air generator 19 is provided in the storage unit 5 and washed in a lowered position. When the tableware is stored and rotated to the raised position, the tableware can be dried in the state of being stored in the storage unit 5, and a useful tableware dryer that does not occupy the narrow kitchen table 6 or the like can be configured. it can.
[0035]
Furthermore, as shown in FIG. 7, if the storage part 1 is formed in a rack shape that passes through from the front side to the rear side, the storage part 1 can be used from both the kitchen side and the dining side like a facing kitchen. This configuration can be further developed, as shown in FIG. 8, by suspending the storage unit 5 between the kitchen and the dining room so that the storage unit 1 can be rotated between the kitchen side and the dining side. , The use on both sides can be further improved.
[0036]
The embodiment described above has been described as a specific example when the lifting and lowering storage device A is used in a kitchen, but can be effectively utilized even when used in other places. For example, in offices, etc., a space for storing articles such as toner cartridges, thermal paper, storage disks, cleaners, manuals, etc. that are not used at all times is provided by making effective use of the upper space of copiers, facsimiles, computers, etc. be able to. Further, in a work space such as a factory, it can be used as a storage place for tools, measuring instruments, supplementary parts, and the like.
[0037]
【The invention's effect】
As described above, according to the first invention of the present application, since the storage portion can be lowered from the upper position to the lower position just below by rotating, the lifting distance is increased and the upper position is set to a higher position. If it is lowered, articles stored freely can be taken in and out. Further, when the lowered lower position is directly below the upper position, there is no protrusion to the front surface of the storage portion, and even if there is a work table or the like below, it is less likely to hinder the work in the lowered state. In addition, it is possible to perform an operation involving taking in and out of articles in the storage unit.
[0038]
Further, since the raising / lowering from the upper position to the lower position just below it is performed by turning, not by linear movement, the raising / lowering operation, particularly the movement in the ascending direction, is facilitated as compared with the vertical raising / lowering operation. be able to.
[0039]
In addition, even in the case of one-point support rotation by the support member, since the belt is stretched between the fixed wheel fixed to the rotation fulcrum and the rotation wheel fixed to the support fulcrum of the storage unit, The rotating wheel is restrained from tilting the posture of the storage unit under the tension of the posture maintaining belt, and a constant posture is maintained.
In addition, the pair of support members can be rotated synchronously by connecting both of them with a connecting shaft, and this connecting shaft is provided at the upper corner of the receiving portion, so that no wasteful space is provided in the receiving portion. It can be arranged.
In particular, when the interlocking belt is spanned between the interlocking wheel and the connecting shaft, and the support members on both sides are rotated synchronously, the rotational speed due to deceleration is reduced because the outer diameter of the connecting shaft is smaller than the outer diameter of the interlocking wheel. A torque that suppresses the movement is applied to the support member, so that a sudden drop due to the weight of the storage portion when the storage portion is lowered can be suppressed.
