Description

【0001】
【発明の属する技術分野】
本発明は、上下に配列した2つの収納部を必要に応じてその上下位置をそれぞれの昇降により入れえられる昇降収納装置に関するものである。
【0002】
【従来の技術】
吊り戸棚は元来、デッドスペースとなりがちな高所空間を有効に利用するのに利用されてきた。しかし、収納部が高所であるため踏み台等を用いないと物を自由に出し入れできない。近時では、吊り戸棚などの高所に設置される収納部を昇降できるように支持し、物の出し入れは下部位置で行い、収納は上部位置で行う昇降収納装置が提案され、実用されている。すなわち図10に示すように、収納部101を平行リンクに構成された支持アーム102に支持させ、収納キャビネット103に内装させたものである。図中104は厨房装置等の作業台である。参考文献としては特開平7−148029号公報、特開平7−148031号公報他があげられる。
【0003】
しかし、このような昇降収納装置では、昇降する高さ距離が小さいためキャビネット103をあまり高い位置に配置することができないという問題点があった。また、収納物により収納部101の重量が増したときに、上昇させるための操作に大きな力を加える必要があり、非力な女性や子供が使用するのに難があった。そして、このような昇降収納装置を図のように厨房装置等の作業台上部に設置した場合では、収納部101はキャビネット103の手前側が下降位置となるので、収納部101を下降させた状態では流し台等の作業台104での作業ができなくなるという課題があった。
【0004】
そこで、本出願人は新たに図11、図12のような昇降収納装置を提案した。すなわち図11、図12の昇降収納装置は、互いに連携する連携手段を設けた2つの収納部を上下に配置することにより、上方の収納部を約180度の回動により降下させると、その勢いで下方の収納部を上昇させて上下位置を入れ換えることができるというものである。具体的には、上下に配列した第1の収納部111と第2の収納部112と、各収納部を支持支点113、114で回転自在に支持して各収納部を連結し、支持支点113、114の間に設定した回転支点115を中心として回転する支持部材116と、回転支点115をその軸線と直角な向きに水平方向に移動できるように支持する摺動支持部117と、第1の収納部111の背部にローラー118を設け、キャビネット119の背板119aにローラー118を当接させる構成としたものである。120は収納部112に設けられた把手である。
【0005】
この昇降収納装置は、使用者が把手120を握り、収納部112を前方に引き出すと、収納部112を支持し、収納部111と連結させている支持部材116が回転支点115を中心として回転するので、収納部112は上昇方向へ移動すると同時に収納部111を下降方向へと移動させる。収納部111の背部に設けられたローラー118は背板119aに当接し、移動時における収納部111の後方への突出を許さない構成としているので、支持部材116は回転支点115を摺動支持部117を介して前方へ移動させ、収納部111、112の干渉を最小限に抑えながら入れえ動作を完了する。
【0006】
このように、本提案による昇降収納装置により、昇降する高さ距離を従来より大きく取ることが可能となり、より高い位置への設置が実現できると共に、各収納部の重量が増したときでも、一方の収納部の下降の勢いによりもう一方の収納部を上昇方向への力を軽減することができ、非力な女性や子供や高齢者にとっても使いやすい昇降収納装置を実現することが可能となった。加えて180度の回動により収納部の収納箱体より前方への突出分がなくなるので、収納部を下降させた状態での流し台等の作業台での作業が可能となるという効果があった。
【0007】
【発明が解決しようとする課題】
ところが、このような上下入れえ式の昇降収納装置は、収納部が昇降移動するため、動作中に収納物品が落下しないような配慮が必要であると同時に、収納物品の出し入れ性についても良好なことが要求されるものである。
【0008】
本発明は上下入れえ収納機能を生かしながら、収納物品の保管安定性や出し入れ作業性にも優れた昇降収納装置を提供するものである。
【0009】
【課題を解決するための手段】
上記課題を解決するため、本発明の昇降収納装置は、上下に配列した第1、第2の各収納部において、水平移動と回転移動により昇降動作する第1の収納部の前方には、収納物品の落下を防止する手段を設け、鉛直方向に昇降動作する第2の収納部は前方を開放状態としている。
【0010】
第1の収納部は、水平移動成分により前後方向に慣性力が働きやすい昇降動作特性を有しており、不安定な収納物品などは倒れやすくなりがちであるが、収納部の前方に落下防止手段を設けることにより、安心して収納することができる。また第2の収納部は、水平移動成分が無く垂直移動のみで昇降運動するが、昇降機構上、その上死点と下死点の近傍において徐動停止する動作特性を有し、急激な慣性力が働かないため収納物品が倒れる心配はほとんど無く、この収納部は前方を開放状態とし、収納物品の出し入れにおいて邪魔になるものが無い構成としており、その作業性を良好なものとしている。
【0011】
これにより、上下入れえ収納機能の利便性を生かしながら、収納物品の保管安定性と出し入れ性の最大効果を出現させることができる。
【0012】
【発明の実施の形態】
本発明の請求項1にかかる昇降収納装置は、上下配列位置に配列した第1、第2の各収納部と、前記第1、第2の各収納部を支持アームの両端部に回動自在に支持して第1の収納部と第2の収納部とを連結し、支持アームの中間部に設けた回転支点で回転することにより前記第1、第2の各収納部の上下位置を入れ換え可能に支持する収納部支持手段と、前記回転支点をその軸線と直角な向きに水平移動できるように支持する摺動支持部と、一方の収納部をほぼ鉛直方向に移動させる案内手段と、前記第1の収納部は前面に出し入れ開口を有し、前記開口の全面又は一部を開閉可能にするガード体を備えたものである。
【0013】
従って、昇降動作において前後に揺れを生じる第1の収納部は、収納物品が前方に倒れて落下しようとしても、収納部に設けた棚の前方立ち上がり部、若しくは収納部前面開口に設けられたガード体で収納物品が保持されるため収納物品の前方への落下が防止される。そして、昇降動作において揺れがなく、また急激な昇降慣性力も働かない第2の収納部は、収納物品の落下の恐れがなく、前方をほぼ開放状態にした収納構造としているため、収納物品の出し入れ性も良好なものとなる。
【0014】
本発明の請求項2にかかる昇降収納装置は、上下配列位置において、第1、第2の収納部の上下位置を入れ換えても、支持支点の軸がほぼ垂直位置に配列する構成であり、これにより収納部を上下入れ換えても収納部が収納箱体より前方への突出することがない。
【0015】
本発明の請求項にかかる昇降収納キャビネットは、本発明の昇降収納装置を前面が開口したキャビネットの内部に配設することにより、キャビネット内の収納が上下入れえ収納機能の利便性を生かしながら、収納物品の保管安定性と出し入れ性の最大効果を出現させることができるものである。
【0016】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【0017】
(実施例1)
図1〜図7は本発明の実施例1を示す。
【0018】
まず、実施例1が採用している昇降機構を、図1〜図5を用いて説明する。
【0019】
図1は本発明の実施例1における昇降機構の説明のための側方断面図である。図2は同実施例における昇降機構の正面要部断面図である。図3は同実施例における昇降機構のキャビネットを除いた状態における斜視図である。図4は一方の昇降機構を正面から見た要部断面図である。図5(a)〜(g)は同実施例における昇降機構の入れえ動作順序を説明する側方断面図である。
【0020】
図1が示すように、昇降機構1は、第1の収納部2の支持支点P1と第2の収納部3の支持支点P2との間を連結する支持アーム4からなる収納部支持手段と、収納部2、3をその上下配置位置において収容し前面を開口したキャビネット5の両側板に取り付けられて前記支持アーム4の回転支点Oを水平方向に移動自在に支持する摺動支持部6と、第1の収納部2を回転角度にかかわらず一定の水平姿勢に維持する第1の姿勢規制手段7aと、第2の収納部3の水平姿勢を維持する第2の姿勢規制手段7bと、その昇降時の移動経路を規制する案内手段8とを備えている。そして上記案内手段8を構成するガイド9aはキャビネット5の背面に取り付けられ、ガイド9aは第2の収納部3の背部の上下に設けられたガイドローラー9bを受け入れて前後の移動を阻止し、収納部3を垂直方向にだけ動くように案内する。
【0021】
以上の昇降機構1は図2に示すように、左右対称位置に昇降機構1L、1Rとして配備され、各支持アーム4L、4Rの各回転支点O間は連結軸10で連結され、左右の昇降機構1L、1Rが同期して動作するように構成されている。これにより第1、第2の各収納部2、3は左右が一体に支持され、収納物の片寄りにより荷重が左右でアンバランスな状態でも、ねじれたり傾くようなことがなく、左右の動きに差が生じるようなことが解消される。
【0022】
図4に示す昇降機構1Lを例にしてさらに説明すると、支持アーム4Lはその回転支点Oに対応する中間部で連結軸10により連結され水平移動軸11Lによりキャビネット12の側板内面に回動自在に支持され、水平移動軸11Lはその上下に配したローラ13a、13bを摺動支持部6Lの上下にコの字状の断面形状に形成された凹部に装入させ、摺動支持部6Lを水平方向に円滑に移動できるようにされている。また、水平移動軸11Lの先端には固定プーリ14Lが回転支点Oと同心で固定されている。
【0023】
支持アーム4Lの両端部の支持支点P1,P2位置に固定された軸15La、15Lbにはそれぞれ回転プーリ16Lと回転輪17Lが同心で回動自在に装着され、この回転プーリ16Lには第1の収納部2が、回転輪17Lには第2の収納部3が、それぞれ側板2L、3Lのほぼ中央部で固定支持されている。
【0024】
上記の固定プーリ14Lと回転プーリ16Lは同径寸法に設定され、両者間にはタイミングベルト18が掛け渡され、第1の姿勢規制手段7aを構成している。
【0025】
ここで、昇降機構1による各収納部2、3の昇降動作について図5の(a)〜(g)に基づき説明する。
【0026】
図5の(a)に示すようにキャビネット5に収納された第1の収納部2と第2の収納部3との上下位置を入れ換えるときには、ガイドローラー9bを持たない第1の収納部2の操作ハンドルAを手前に引き出す。すると第1の収納部2は支持支点P1が支持アーム4の回転支点Oを中心として前方に回動されるので、第2の収納部3は支持支点P2が後方に回動しようとするが、第2の収納部3側はガイドローラー9bをガイド9a押し付けて受け止められていることにより垂直方向の案内を受けるので、支持アーム4が回動する動作でその回転支点Oを摺動支持部6内で水平方向に押し出しながら、図5(b)〜(d)に示すように第2の収納部3は第1の収納部2の回動に伴って垂直方向に上昇する。
【0027】
図5(d)に示す状態からさらに第1の収納部2を回動させると、前記と反対に支持アーム4の回動支点Oはキャビネット5庫内奥方向に引き寄せられ、図5の(e)〜(f)に示すように、第1の収納部2は回動しつつキャビネット5内の下方に進入して行くのに連動して、第2の収納部3は垂直方向にさらに上昇し、図5の(g)に示すように第1の収納部2が第2の収納部3が元配列されていた下方位置に入ったとき、第2の収納部3は第1の収納部2が元配列されていた上方位置に上昇して、第1の収納部2と第2の収納部3との配列位置が上下入れ替わる。
【0028】
図5の(g)に示す状態から第1の収納部2を引き出し、上記操作と逆方向に回動させると、第2の収納部3は垂直方向に下降し、図5の(f)〜(a)の逆動作でそれぞれ元の配列位置に復帰させることができる。
【0029】
このような各収納部2、3の上下入れえ動作において、第1の収納部2は支持アーム4によって支持支点P1に1軸で回動自在に支持されているので、支持支点P1に対する第1の収納部2の重心のずれや第1の収納部2の回動操作により水平姿勢が傾こうとする。ここで第1の収納部2に固定支持されている回転プーリ16は回転支点Oにある固定プーリ14との間でタイミングベルト18が掛け渡され、滑りのない形で回転連動している。今、回転プーリ16と固定プーリ14は同径に設定しており、タイミングベルト18は第1の収納部2が回動して支持アーム4の支持角度が変化する方向と逆の方向に同角度だけ第1の収納部2を回転させる働きを営み、結果として第1の収納部2は常にその水平姿勢を維持することができる。
【0030】
次に前記の昇降機構をベースに、収納部に収納用の棚を配した本願発明の実施例1を図6、図7を用いて説明する。
【0031】
なお、図6(a)〜(g)は本実施例における入れえ動作順序を説明する側方断面図である。図7は同実施例における昇降収納装置の正面要部断面図である。
【0032】
第1と第2の収納部2、3は前面に開口を有する箱体で構成され、第1の収納部2の両側面には棚19を保持する棚受け20が取り付けられている。棚19は棚受け20の位置を収納部の両側面に上下配置された係止穴21に付け替えることにより上下位置調整が可能となっている。また棚19は前端を折り曲げ、立ち上がり部22を形成している。
【0033】
一方、第2の収納部3には棚23a、23bが設けられ、上段の棚23aは上下に設けられた棚受け24の任意の位置にセットできるようになっており、棚23a、23bの前端部は平坦な形状としている。
【0034】
ここで図6(a)〜(g)の昇降動作のように、第1の収納部2は水平移動しながら回転していく昇降動作をとるが、操作ハンドルAを急に引き出したり押し込んだりして昇降操作を行うと前後方向に大きな慣性力が働くため、細長いビンや缶などの不安定な収納物品25は棚19から前後方向にずれたり倒れようとする。しかしながら、棚19には立ち上がり部22が形成されており、収納物品25のずれや倒れを保持し前方への落下の危険を防止する。
【0035】
次に第二の収納部3の昇降運動は水平移動成分が無く垂直移動成分のみであるため、前後方向への慣性力が全く働かない。また垂直移動についても第二の収納部3は図6(a)の下死点や(g)の上死点に近づくにつれ徐動運動となり停止する特性がある。すなわち、図6(f)から(g)の上死点への移動を見てみると、操作ハンドルAによる操作回転角θに対し垂直移動距離Tは微少となり、極めてソフトな減速停止運動となる。このように第二の収納部3の昇降動作は極めて安定しており、収納物品26はほとんど移動や落下する心配がない。そこで、第二の収納部3の棚23は前方に立ち上がりを設けずフラットな形状としてある。よって開口面積が大きくなり、収納物品26の出し入れ性が極めて良好なものとなる。なお、棚23a、23bは収納物品26から漏れた汁垂れを防止するなどの目的で、トレイ状に周囲に小許の立ち上げ部を形成しても、収納物品26の出し入れ性を損なうようなことはなく、ほぼ同様の作用効果が得られる。
【0036】
なお、本実施例の棚19、23は棚受け20、24を任意の係止孔21に付け替えることにより移動可能としているが、ビスその他の手段により固定棚としても良い。
【0037】
(実施例2)
次に、本発明の実施例2の収納部の棚を図8、図9を用いて説明する。
【0038】
なお、図8(a)〜(g)は実施例2における昇降収納装置の入れえ動作順序を説明する側面図である。図9は同実施例における昇降収納装置の正面要部断面図である。
【0039】
なお、実施例1と同一符号のものは同一構造を有し、説明は省略する。
【0040】
本実施例2において実施例1と異なる点は、第1の収納部2の棚19は前方に立ち上がり部を設けず、収納部2の前面に開閉自在なガード体27を配した点である。ガード体27は収納部2の前面下方位置に設けられた軸28を支点として上下方向に開閉する網形状で、キャッチ29で閉成保持されるようになっており、このガード体27により収納物品25の落下が防止される。また第2の収納部3は前面を開放状態とし、収納物品26の出し入れ性を良好なものとしているところは実施例1と同様である。
【0041】
なお、本実施例2のガード体27は収納部2の前面下方位置に設けられた軸28を支点として上下方向に開閉する構成としているが、軸28を収納部2の左右どちらか一方に設け、キャッチ29をその相対する部分に設けて左右に開閉するものとしてもよいし、収納部2の前面をカバーし、収納物品25の転落を防止するものであれば、ガード体27のような網形状に限らず、どのような形状でもかまわない。要するに本願発明の目的を達成できればよいものであり、開閉方法やガード体の形状は無数にあるものと思われる。
【0042】
【発明の効果】
以上説明したように本発明の昇降収納装置は、収納物品の出し入れし易い高さに各収納部の上下配置を簡単に上下入れえすることができ、これにより高所収納部や低所収納部の収納品出し入れ性が大きく向上し、空間の有効活用が促進される。また各収納部の昇降動作特性に最適な収納形態を構成しているため、極めて使い勝手や安全性の高い昇降収納装置となる。
【0043】
すなわち、第1の収納部は、水平移動成分により前後方向に慣性力が働きやすい昇降動作特性を有しており、不安定な収納物品などは倒れやすくなりがちであるが、収納部の前方に落下防止構造を設けることにより、安心して収納することができる。また第2の収納部は、水平移動成分が無く垂直移動のみで昇降運動するが、昇降機構上、その上死点と下死点の近傍において徐動停止する動作特性を有し、急激な慣性力が働かないため収納物品が倒れる心配はほとんど無く、この収納部は前方を開放状態とし、収納物品の出し入れにおいて邪魔になるものが無い構成としており、その作業性を良好なものとしている。
【0044】
また、出し入れ頻度の多い物品や振動や衝撃を嫌う物品、例えば食器類などは水平移動成分を持たず全面開口面積の大きい第2の収納部側に収納するようにすれば、出し入れ作業性が良くしかも安心して収納保管しておくことができるし、また例えば乾物類や貯蔵食品などの振動や衝撃に大した影響を受けない物品は第1の収納部側に収納しておけば、昇降動作中に落下する心配もなく、このように各収納部をうまく使い分けて収納することにより、極めて便利な昇降収納装置を実現することができる。
【0045】
上記により明白なように、本発明は上下入れえ収納機能の利便性を生かしながら、収納物品の保管安定性と出し入れ性の最大効果を出現させることができるという効果を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to conversion Erareru lifting housing device placed by a respective lifting the upper and lower positions as needed two housing portions arranged vertically.
[0002]
[Prior art]
The hanging cupboard has been originally used to effectively use the high space that tends to be a dead space. However, since the storage section is high, objects cannot be taken in and out without using a step or the like. Recently, a storage unit installed in a high place such as a hanging cupboard is supported so that it can be moved up and down, and an elevating storage device is proposed and put into practical use in which the storage and removal of objects is performed at the lower position and storage is performed at the upper position. . That is, as shown in FIG. 10, the storage unit 101 is supported by a support arm 102 configured as a parallel link, and is housed in a storage cabinet 103. In the figure, 104 is a work table such as a kitchen apparatus. References include JP-A-7-148029 and JP-A-7-148031.
[0003]
However, such a lifting and lowering storage device has a problem that the cabinet 103 cannot be arranged at a very high position because the height distance to be lifted is small. In addition, when the weight of the storage unit 101 is increased due to the stored items, it is necessary to apply a large force to the operation for raising the storage unit 101, which is difficult for a weak woman or child to use. And when such a raising / lowering storage apparatus is installed in the upper part of work benches, such as a kitchen apparatus, as shown in the figure, since the storage part 101 is in the lowered position on the front side of the cabinet 103, in the state where the storage part 101 is lowered, There was a problem that work on the work table 104 such as a sink could not be performed.
[0004]
Therefore, the present applicant has newly proposed a lifting and lowering storage device as shown in FIGS. That is, in the lifting and lowering storage device of FIGS. 11 and 12, when the upper storage portion is lowered by about 180 degrees by disposing the two storage portions provided with the cooperation means that cooperate with each other vertically, the momentum is increased. Thus, the lower storage part can be raised to change the vertical position. Specifically, the first storage unit 111 and the second storage unit 112 arranged in the vertical direction, the storage units are rotatably supported by support fulcrums 113 and 114, and the storage units are connected to each other. , 114, a support member 116 that rotates about a rotation fulcrum 115, a sliding support 117 that supports the rotation fulcrum 115 so that it can move in a direction perpendicular to its axis, and a first A roller 118 is provided on the back of the storage unit 111, and the roller 118 is brought into contact with the back plate 119 a of the cabinet 119. Reference numeral 120 denotes a handle provided in the storage unit 112.
[0005]
In this lifting and lowering storage device, when the user holds the handle 120 and pulls the storage portion 112 forward, the support member 116 that supports the storage portion 112 and is connected to the storage portion 111 rotates around the rotation fulcrum 115. Therefore, the storage unit 112 moves in the upward direction and simultaneously moves the storage unit 111 in the downward direction. Since the roller 118 provided on the back of the storage unit 111 is in contact with the back plate 119a and does not allow the storage unit 111 to protrude rearward during movement, the support member 116 supports the rotation fulcrum 115 as a sliding support unit. 117 is moved forward through a complete conversion example operation put with minimal interference of the housing portions 111 and 112.
[0006]
In this way, the lifting and lowering storage device according to the present proposal makes it possible to increase the height of the lifting and lowering as compared with the conventional case, and it can be installed at a higher position, and even when the weight of each storage portion increases, Due to the lowering moment of the storage part, it was possible to reduce the force in the upward direction of the other storage part, and it became possible to realize a lifting storage device that is easy to use for less powerful women, children and elderly people . In addition, since the portion of the storage portion protruding forward from the storage box body is eliminated by the rotation of 180 degrees, there is an effect that it is possible to work on a work table such as a sink in a state where the storage portion is lowered. .
[0007]
[Problems to be solved by the invention]
However, such vertical insertion conversion example type lifting housing device, since the housing portion moves up and down, at the same time as the stored articles during operation care should be taken so as not to fall, better for the loading and unloading of the stored articles That is what is required.
[0008]
The present invention while taking vertical insertion conversion example storage function is to provide a lifting housing device excellent in storage stability and out workability stored articles.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, the lifting and lowering storage device of the present invention has a first and second storage units arranged in the upper and lower directions, and is stored in front of the first storage unit that moves up and down by horizontal movement and rotational movement. A means for preventing the article from falling is provided, and the second storage portion that moves up and down in the vertical direction is open at the front.
[0010]
The first storage unit has a lifting / lowering characteristic in which the inertial force tends to work in the front-rear direction due to the horizontal movement component, and unstable storage articles tend to fall down, but fall prevention to the front of the storage unit By providing the means, it can be stored with peace of mind. In addition, the second storage unit has a horizontal movement component and moves up and down only by vertical movement. However, the second storage unit has an operating characteristic that stops slowly in the vicinity of the top dead center and the bottom dead center on the lifting mechanism, and has a sudden inertia. Since the force does not work, there is almost no fear that the stored article will fall down, and this storage section is open at the front, so that there is no obstacle to putting in and out the stored article, and the workability is good.
[0011]
Thus, it is possible while taking convenience of the upper and lower insertion conversion example storage functions, to reveal the maximum effect of the loading and unloading of the storage stability of the stored articles.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
Example 1
1 to 7 show Embodiment 1 of the present invention.
[0018]
First, the elevating mechanism employed in the first embodiment will be described with reference to FIGS.
[0019]
FIG. 1 is a side sectional view for explaining an elevating mechanism in Embodiment 1 of the present invention. FIG. 2 is a front cross-sectional view of the main part of the lifting mechanism in the same embodiment. FIG. 3 is a perspective view of the lift mechanism in the same embodiment with the cabinet removed. FIG. 4 is a cross-sectional view of a main part when one lifting mechanism is viewed from the front. Figure 5 (a) ~ (g) is a side sectional view illustrating a charged conversion example operating sequence of the lifting mechanism in the same embodiment.
[0020]
As shown in FIG. 1, the elevating mechanism 1 includes a storage unit support unit including a support arm 4 that connects a support fulcrum P <b> 1 of the first storage unit 2 and a support fulcrum P <b> 2 of the second storage unit 3; A sliding support portion 6 that accommodates the storage portions 2 and 3 at the upper and lower arrangement positions and is attached to both side plates of the cabinet 5 whose front surface is open, and supports the rotation fulcrum O of the support arm 4 movably in the horizontal direction; A first attitude regulating means 7a for maintaining the first storage section 2 in a constant horizontal attitude regardless of the rotation angle; a second attitude regulating means 7b for maintaining the horizontal attitude of the second storage section 3; And a guide means 8 for restricting the moving path during the ascending and descending. The guide 9a constituting the guide means 8 is attached to the back surface of the cabinet 5, and the guide 9a receives guide rollers 9b provided at the top and bottom of the back of the second storage unit 3 to prevent the back and forth movement and store it. The part 3 is guided so as to move only in the vertical direction.
[0021]
As shown in FIG. 2, the elevating mechanism 1 is provided as elevating mechanisms 1L and 1R at symmetrical positions, and the rotation fulcrums O of the support arms 4L and 4R are connected by a connecting shaft 10, and left and right elevating mechanisms are provided. 1L and 1R are configured to operate in synchronization. As a result, the left and right sides of the first and second storage units 2 and 3 are integrally supported, and the left and right movements are prevented from being twisted or tilted even when the load is unbalanced between the left and right sides due to the offset of the stored items. This eliminates the difference between the two.
[0022]
Further explanation will be given by taking the lifting mechanism 1L shown in FIG. 4 as an example. The support arm 4L is connected by a connecting shaft 10 at an intermediate portion corresponding to the rotation fulcrum O, and is rotatable to the inner surface of the side plate of the cabinet 12 by a horizontal moving shaft 11L. The horizontal movement shaft 11L is supported, and the rollers 13a and 13b arranged above and below are inserted into recesses formed in a U-shaped cross section above and below the sliding support 6L, and the sliding support 6L is placed horizontally. It can move smoothly in the direction. A fixed pulley 14L is concentrically fixed to the rotation fulcrum O at the tip of the horizontal movement shaft 11L.
[0023]
A rotating pulley 16L and a rotating wheel 17L are concentrically and rotatably mounted on the shafts 15La and 15Lb fixed to the supporting fulcrums P1 and P2 at both ends of the supporting arm 4L, respectively. The storage portion 2 is fixedly supported by the rotating wheel 17L at the substantially central portion of the side plates 2L and 3L.
[0024]
The fixed pulley 14L and the rotating pulley 16L are set to have the same diameter, and a timing belt 18 is stretched between them to constitute the first posture regulating means 7a.
[0025]
Here, the raising / lowering operation | movement of each accommodating part 2 and 3 by the raising / lowering mechanism 1 is demonstrated based on (a)-(g) of FIG.
[0026]
As shown in FIG. 5A, when the upper and lower positions of the first storage unit 2 and the second storage unit 3 stored in the cabinet 5 are switched, the first storage unit 2 that does not have the guide roller 9b. Pull out the operation handle A. Then, since the support fulcrum P1 of the first storage unit 2 is rotated forward about the rotation fulcrum O of the support arm 4, the second storage unit 3 tries to rotate the support fulcrum P2 backward. Since the second storage unit 3 side receives the guide in the vertical direction by pressing the guide roller 9b against the guide 9a, the support arm 4 rotates so that the rotation fulcrum O is moved inside the sliding support unit 6. As shown in FIGS. 5B to 5D, the second storage portion 3 rises in the vertical direction as the first storage portion 2 rotates.
[0027]
If the 1st accommodating part 2 is further rotated from the state shown in FIG.5 (d), contrary to the above, the rotation fulcrum O of the support arm 4 will be drawn near in the cabinet 5 inside, and (e) of FIG. As shown in (f) to (f), the second storage part 3 further rises in the vertical direction in conjunction with the first storage part 2 entering the lower part of the cabinet 5 while rotating. As shown in FIG. 5G, when the first storage part 2 enters the lower position where the second storage part 3 was originally arranged, the second storage part 3 becomes the first storage part 2. Rises to the upper position where the original arrangement was made, and the arrangement positions of the first storage unit 2 and the second storage unit 3 are switched up and down.
[0028]
When the first storage unit 2 is pulled out from the state shown in FIG. 5G and is rotated in the direction opposite to the above operation, the second storage unit 3 is lowered in the vertical direction, and FIGS. The original arrangement position can be restored by the reverse operation of (a).
[0029]
In such vertical insertion conversion example operations of the respective housing portions 2 and 3, the first housing section 2 is rotatably supported by the first shaft to the supporting fulcrum P1 by the support arms 4, the relative support fulcrum P1 The horizontal posture tends to be tilted by a shift of the center of gravity of the first storage unit 2 or a rotation operation of the first storage unit 2. Here, the timing pulley 18 is spanned between the rotary pulley 16 fixedly supported by the first storage portion 2 and the fixed pulley 14 at the rotation fulcrum O, and is interlocked with the rotation without slipping. Now, the rotary pulley 16 and the fixed pulley 14 are set to have the same diameter, and the timing belt 18 has the same angle in the direction opposite to the direction in which the support angle of the support arm 4 changes as the first storage portion 2 rotates. As a result, the first storage unit 2 can always maintain its horizontal posture.
[0030]
Next, a first embodiment of the present invention in which a storage shelf is arranged in the storage portion based on the lifting mechanism will be described with reference to FIGS.
[0031]
Incidentally, FIG. 6 (a) ~ (g) is a side sectional view illustrating a conversion example operation sequence placed in this embodiment. FIG. 7 is a front cross-sectional view of the main part of the lifting and lowering storage device in the same embodiment.
[0032]
The first and second storage units 2 and 3 are formed of a box having an opening on the front surface, and shelf receivers 20 that hold the shelves 19 are attached to both side surfaces of the first storage unit 2. The shelf 19 can be adjusted in the vertical position by changing the position of the shelf holder 20 to the locking holes 21 arranged on both sides of the storage unit. Further, the shelf 19 is bent at the front end to form a rising portion 22.
[0033]
On the other hand, the second storage unit 3 is provided with shelves 23a and 23b, and the upper shelf 23a can be set at an arbitrary position of the shelf receiver 24 provided above and below, and the front ends of the shelves 23a and 23b. The part has a flat shape.
[0034]
Here, as shown in FIGS. 6 (a) to 6 (g), the first storage unit 2 performs an elevating operation that rotates while moving horizontally, but suddenly pulls out or pushes in the operation handle A. When the lifting / lowering operation is performed, a large inertial force acts in the front-rear direction. Therefore, the unstable storage article 25 such as an elongated bottle or a can tends to be displaced from the shelf 19 in the front-rear direction or to fall down. However, a rising portion 22 is formed on the shelf 19 to keep the stored article 25 from shifting or falling and prevent the risk of falling forward.
[0035]
Next, since the vertical movement of the second storage unit 3 has no horizontal movement component and only a vertical movement component, inertia force in the front-rear direction does not work at all. As for the vertical movement, the second storage unit 3 has a characteristic that it gradually moves and stops as it approaches the bottom dead center of FIG. 6A or the top dead center of FIG. That is, when looking at the movement from FIG. 6 (f) to (g) to the top dead center, the vertical movement distance T with respect to the operation rotation angle θ by the operation handle A becomes very small, resulting in an extremely soft deceleration stop motion. . As described above, the raising / lowering operation of the second storage unit 3 is extremely stable, and the stored article 26 is hardly moved or dropped. Therefore, the shelf 23 of the second storage unit 3 has a flat shape without providing a rise in the front. Therefore, the opening area is increased, and the storage / removal property of the stored article 26 is extremely good. It should be noted that the shelves 23a and 23b may impair the ability to put in and out the storage article 26 even if a permissible rising portion is formed around the tray for the purpose of preventing dripping from the storage article 26. In other words, almost the same effect can be obtained.
[0036]
The shelves 19 and 23 of the present embodiment can be moved by replacing the shelf holders 20 and 24 with arbitrary locking holes 21, but may be fixed shelves by screws or other means.
[0037]
(Example 2)
Next, the shelf of the storage unit according to the second embodiment of the present invention will be described with reference to FIGS.
[0038]
Incidentally, FIG. 8 (a) ~ (g) is a side view illustrating a charged conversion example operating sequence of the lifting housing apparatus according to the second embodiment. FIG. 9 is a front cross-sectional view of the main part of the lifting / lowering storage device in the same embodiment.
[0039]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0040]
The second embodiment is different from the first embodiment in that the shelf 19 of the first storage unit 2 is not provided with a rising portion in the front, and a guard body 27 that can be opened and closed is arranged on the front surface of the storage unit 2. The guard body 27 has a net shape that opens and closes in a vertical direction with a shaft 28 provided at a lower position on the front surface of the storage unit 2 as a fulcrum, and is closed and held by a catch 29. 25 is prevented from falling. Further, the second storage unit 3 is the same as the first embodiment in that the front surface is in an open state and the storage and removal of the stored articles 26 is good.
[0041]
The guard body 27 of the second embodiment is configured to open and close in the vertical direction with a shaft 28 provided at a lower position on the front surface of the storage unit 2 as a fulcrum. However, the shaft 28 is provided on either the left or right side of the storage unit 2. The catch 29 may be provided on the opposite part to open and close to the left and right, or a net such as the guard body 27 as long as it covers the front surface of the storage unit 2 and prevents the stored article 25 from falling. Not only the shape but also any shape may be used. In short, it is only necessary to achieve the object of the present invention, and it seems that there are innumerable opening and closing methods and shapes of guard bodies.
[0042]
【The invention's effect】
Lifting housing device of the present invention described above, the vertical arrangement of the housing part briefly out easily the height of the stored articles can vertically inserting conversion demarcating, thereby altitude housing part and low-income housing The storage / removability of the storage parts is greatly improved, and the effective use of the space is promoted. Moreover, since the storage form optimal for the lifting operation characteristics of each storage unit is configured, the lifting storage apparatus is extremely easy to use and highly safe.
[0043]
That is, the first storage unit has a lifting operation characteristic in which an inertial force tends to work in the front-rear direction due to a horizontal movement component, and unstable storage articles tend to fall down, but in front of the storage unit. By providing the fall prevention structure, it can be stored with peace of mind. In addition, the second storage unit has a horizontal movement component and moves up and down only by vertical movement. However, the second storage unit has an operating characteristic that stops slowly in the vicinity of the top dead center and the bottom dead center on the lifting mechanism, and has a sudden inertia. Since the force does not work, there is almost no fear that the stored article will fall down, and this storage section is open at the front, so that there is no obstacle to putting in and out the stored article, and the workability is good.
[0044]
Also, articles that are frequently put in and out, and articles that do not like vibration or impact, such as tableware, can be put in and out easily if they are stored in the second storage section with a large opening area and no horizontal movement component. In addition, it can be stored and stored with peace of mind, and for example, articles that are not significantly affected by vibrations and shocks such as dry foods and stored foods can be stored in the first storage part side, and the elevator is moving up and down. Thus, there is no worry about falling down, and thus it is possible to realize a very convenient elevating and lowering storage device by properly using and storing the storage units.
[0045]
As apparent by the above, the present invention while taking convenience of the upper and lower insertion conversion example storage function and has an effect of being able to reveal the maximum effect of the loading and unloading of the storage stability of the stored articles.
