Description

【0001】
【産業上の利用分野】
本発明は厨房等で各種の物を収納しておくのに利用する収納部用昇降支持ユニットおよびこれを用いた昇降収納装置に関するものである。
【0002】
【従来の技術】
このような収納部用昇降支持ユニットおよびこれを用いた昇降収納装置は、特開昭61−154610号公報等で知られている。
【0003】
このものは、収納ボードの両側内面に個別に枢支した両側の平行リンクの自由端部間に収納部を支持し、収納部を収納ボードへの格納位置と収納ボードの前部下方に引出し下降させた取出し位置との間で昇降できるようにしている。リンクと固定部との間に引っ張りばねを働かせてリンク対が収納部を低速度で下降させられるようにし、かつ平行リンクが垂直姿勢よりも後方に傾斜した傾斜姿勢にて収納部を格納位置に支持することにより、地震等にても不用意に前方へ張り出し、また取出し位置に下降するようなことを防止し、使用の安全を図っている。
【0004】
【発明が解決しようとする課題】
しかし、上記従来のような構成では、リンクと固定部との間に引っ張りばねを働かせるだけで収納部の下降速度を制限する構造のため、収納部とこれに収納する物との重量が大きければ、強力で長いばねを用いないと十分なダンパー機能を発揮できないので、収納部を取出し位置に下降させる場合の、平行リンクが前方へ大きく傾斜することにより収納部の重量が下降速度を増速するように働くまでは抵抗が大きくなり過ぎ使用しにくいものとなる。
【0005】
また、平行リンクが垂直姿勢よりも後方へ傾斜した傾斜姿勢にて収納部を格納位置に支持することにより使用の安全を図ることはできるが、引っ張りばねは、平行リンクが後方への傾斜姿勢から垂直姿勢に起こした後、さらに取出し位置へ下降させる全工程でダンパーとして働くので、平行リンクが後方への傾斜姿勢から垂直姿勢になるまでは収納部を持ち上げる動作になるのに加え引っ張りばねに抗して行うことになり、静止している重量物を動かし始めるのに大きな力が必要であることと相まって、収納部を取出し位置に引出し下降させる場合の初期動作が重く、使用に不便なものとなっている。
【0006】
本発明は、このような問題を解消することを課題とし、安全性を十分確保してしかも使用に便利な収納部用昇降支持ユニットおよびこれを用いた昇降収納装置を提供することを目的とするものである。
【0007】
【課題を解決するための手段】
本発明の収納部用昇降支持ユニットは、上記のような目的を達成するために、収納部を上昇および下降できるように取り付け基台に枢支した支持手段と、収納部の速度を抑制するダンパー手段と、収納部の下降動作でチャージされる複数のばねとを備え、ばねは選択的に働かせることができる構成としたものである。
【0008】
【作用】
本発明の収納部用昇降支持ユニットは、収納部の速度を抑制するダンパー手段を備えているので、収納物品の重量が支持手段収納部の下降速度を増速させるように働いてもこれをダンパー手段が抑制するので、収納部は低速度で安全に下降する。また、収納部の下降動作でチャージされる複数のばねを選択的に働かせることができる。
【0009】
【実施例】
以下本発明の収納部用昇降支持ユニットおよびこれを用いた昇降収納装置の幾つかの実施例について、図1〜図8を参照しながら説明する。
【0010】
図1〜図6は本発明の第1の実施例を示している。本実施例は図1〜図3に示すように収納部用昇降支持ユニットAを、収納ボードBに収容して、かご形式の収納部Cを昇降できるように支持した収納装置の場合を示している。
【0011】
収納部用昇降支持ユニットAは、図4〜図6に示すように、自由端部間で収納部Cを支持する両側の平行リンク1、2を左右の取付け基台3、4に個別に枢支し、両側の平行リンク1、2の対向し合う前部側のリンク1a、2aを枢支しかつこれに同体回転する枢軸5、6どうしを連結軸17により連結一体化してある。これにより各取り付け基台3、4を一体化するとともに両側の平行リンク1、2が連動するようになる。
【0012】
したがって、各取付け基台3、4に枢支した両側の平行リンク1、2はユニット化した収納部用昇降支持ユニットAを構成するので、これの全体を1つのものとして取扱い、各取付け基台3、4を収納ボードBの両側の内面に双方間の特別な位置合わせ作業を必要とせずに、ねじ10等により容易に取付けることができる。奥側のリンク1b、2bの枢軸7、8どうしをも連結一体化すると、各取付け基台3、4の一体化の剛性および両側の平行リンク1、2の連動剛性をさらに高めることができる。
【0013】
平行リンク1、2は、それぞれの前後のリンク1aと1bの自由端部間、およびリンク2aと2bの自由端部間が、収納部Cを取付ける取付け座1c、2cにより連結されて、収納部Cを支持していない状態で、収納部用昇降支持ユニットA側の完結した平行リンクをなすようにしてある。したがって、平行リンク1、2の自由端部間に収納部Cを支持するには、この取付け座1c、2cを収納部Cの両側板9にねじ10等により取り付ければよい。
【0014】
このような組み立て構造上、収納部用昇降支持ユニットAを収納ボードBに収容して収納部Cを昇降できるように支持した本実施例の収納装置は作業工数少なく容易かつ迅速に組み立てることができる。収納ボードB内の収納部用昇降支持ユニットAによって支持した収納部Cは、両側の平行リンク1、2が各取付け基台3、4上で枢軸5〜8を中心として起伏することにより、収納ボードB内に図1、図2に示すように位置した格納位置と、収納ボードBの前方下部に図3に示すように引出し下降させた取出し位置との間で昇降される。
【0015】
また、両側の平行リンク1、2が連動することにより、両側の平行リンク1、2による収納部Cの支持や動きに差が生じることはなく、両側の平行リンク1、2の自由端部間で支持する収納部Cが図示するかご形式のような簡易な剛性の低いのものであっても、十分な支持剛性を発揮して収納部Cによじれや揺れが生じるのを防止し、全体を軽量かつ小型なものとすることができる。
【0016】
一方、平行リンク1、2の後部側のリンク1b、2bを枢支しかつこれに同体回転する枢軸7、8と取付け基台3、4との間には、平行リンク1、2の収納部Cを取出し位置に下降させる速度を制限するダンパー機構11、12を働かせてある。このダンパー機構11、12は前記枢軸7、8の一方にのみ働かせても、両側の平行リンク1、2が連動するものであることにより、双方に均等に働かせることができるし、本実施例のように2つのダンパー機構11、12を双方に分担して働かせても、これらが同種のものかどうかに係わりなく、両側の平行リンク1、2に均等に働かせることができる。
【0017】
ダンパー機構11、12は、取付け基台3、4の両端部が外側に向け折曲げられた取付け座3a間、および4a間の空間部に収容して働かせてあり、取付け座3a間、および4a間に渡して溶接付けした取付け板20を利用し装備してある。
【0018】
ダンパー機構11、12は枢軸7、8の回転を利用して働かせてあり、リンク1a〜2bとは切り離したリンク1a〜2bの支持構造部に装備し、枢軸5〜8の回転動作を利用してコンパクトに設けることができる。
【0019】
具体的には、一方のダンパー機構11は蔓巻きばね21とロータリ式のオイルダンパ22とを働かせ、他方のダンパー機構12は蔓巻きばね31のみを働かせてある。
【0020】
ダンパー機構11の蔓巻きばね21は、枢軸7の取付け板20の内側に突出した部分のまわりに巻回され、図4、図5に示すように一方の端部21aが、取付け板20の内側面に溶接付けした係止部材25によって受止められ、他方の端部21bが、取付け板20と取付け基台3との間で枢軸5に同体回転するように装着した大径のギヤ26上の複数の取付け穴23のいずれかに取り付けた押動ピン24と遊びSを持って対向している。
【0021】
これによって、平行リンク1、2が図4に示す矢印の方向に伏倒して収納部Cを収納ボードBから引出し下降させる動作にギヤ26が連動して回転すると、押動ピン24は最初前記蔓巻きばね21の端部21bに近づくだけであるが、平行リンク1、2の傾きが大きくなって収納部Cの重量が下動速度を増速させるようになる所定の途中位置にて前記遊びSがなくなり、以降端部21bを押動していって係止部材25により受止められている一方の端部21aとの間で蔓巻きばね21を次第にチャージしていき、収納部Cの重量が下降速度を増速するように影響しても、前記チャージ動作時の抵抗によって前記影響を緩和し、平行リンク1、2が低速で下降できるようにする。
【0022】
オイルダンパ22は取付け板20の内面に取付けられ、これの図6に示す回転軸22aに装着したピニオンギヤ27がギヤ26に噛み合い、平行リンク1、2が伏倒するときの枢軸7の回転が増速して回転軸22aに伝達されるようにしている。
【0023】
したがって、回転軸22aに取り付けた回転羽根22bと、オイルダンパ22内の制動羽根22cとの相対速度が増大され、オイルダンパ22内に封入してあるオイルによる回転羽根22bの回転抵抗を大きくする。これにより平行リンク1、2が起立状態から伏倒し始めて前記蔓巻きばね21が働き始める位置までの引き出し速度を、小さなダンパー容量のものにて十分に制限することができる。
【0024】
他方のダンパー機構12の蔓巻きばね31は、枢軸8とこれに装着した前記ギヤ26に代わる回転盤32とによって、前記蔓巻きばね21とほぼ同様に設けられている。蔓巻きばね31の一方の端部31aを取付け板20に螺合させた係止ボルト33によって受止めた点が、蔓巻きばね21の場合と異なっている。
【0025】
係止ボルト33はこれを回転させることによって、前記端部31aと対向する位置に進出したり、この対向位置から後退させたりすることができる。係止ボルト33を後退位置としておくことにより、蔓巻きばね31の他方の端部31bが回転盤32上の押動ピン24によって、一方の端部31aの側に押動されてもこの端部31aを係止ボルト33が受止めないので、蔓巻きばね31は枢軸8のまわりに空回りされるだけで、平行リンク1、2にダンパー機能を及ぼさない。しかし、係止ボルト33を進出位置としておくことにより、蔓巻きばね31の端部31bが押動ピン24によって端部31aの側に押動されると、この端部31aを係止ボルト33が受け止めて逃がさないので、蔓巻きばね31が両端部31a、31b間でチャージされ、蔓巻きばね21と同様に平行リンク1、2にダンパー機能を及ぼす。
【0026】
これにより、係止ボルト33を進退させてダンパー機構12を働かせたり、働かせなかったりすると、収納部Cに収納するものの重量に合わせて、ダンパー機能を高めたり、弱めたりすることができる。もっともこのような複数の蔓巻きばねを同一の枢軸に装着して、選択的に働かせることもできる。
【0027】
ギヤ26には円弧状の長穴26aが設けられ、これに取付け基台3および取付け板20間に確固に取り付けたストッパーピン34が通るようにしてある。収納部Cが取出し位置まで下降する平行リンク1、2の伏倒位置にて、長穴26aの端部がストッパーピン34に当接し平行リンク1、2がそれ以上下方に回動しないようにする。これによって、収納部Cが前記所定の取出し位置を越えて過剰に下降されるようなことがないようにしている。
【0028】
枢軸5、6を連結した連結軸17は、例えば図に示すようなパイプ部材とし、枢軸5、6の取付け基台3、4から突出している端部5a、6aに嵌め合わせてねじ35により固定してあり、異なった長さの連結軸17を選択して使用し、あるいは取り替えられるようにしてある。これにより収納ボードBの横サイズの異なるものに対応し、この収納ボードBに適した大きさの収納部Cを昇降できるように支持することができる。収納部Cの両側板9の前部下間には、昇降動作用の把手9aが取付けられている。
【0029】
収納ボードBの両側内面には、各取付け基台3、4を取付けるためのねじ穴36を多段に設けてあり、収納ボードBの高さに対して収納部用昇降支持ユニットAの収納部Cを支持した状態の全高よりも高い場合に、収納部用昇降支持ユニットAを使用者の背の高さに応じて収納ボードBへの取付け高さを自由に変えられるようにしてある。
【0030】
図7、図8は本発明の第2の実施例としての昇降収納部用の下降ダンパー装置を示している。本実施例は収納部用昇降支持ユニットAの起伏する平行リンク1、2により収納部Cを格納位置とこの格納位置の前方下部へ引き出した取出し位置との間で昇降できるように支持して収納ボードBに収容して取付け、収納部Cの下降速度を制限するダンパー機構11を働かせた点で第1の実施例の場合と共通している。
【0031】
本実施例では特に平行リンク1は図7(a)に示すように、垂直姿勢よりも後方側に傾斜した傾斜姿勢で収納部Cを格納位置に支持し、この傾斜姿勢から図8(a)に示す垂直姿勢の直前またはほぼ垂直姿勢になる位置まで、ダンパー機構11との間に遊びを設けてある。具体的には、図7(b)に示すようダンパー機構11のロータリダンパ22におけるギヤ26と枢軸7との間に所定回転範囲の遊びSSを設けてある。
【0032】
これにより、平行リンク1、2の起伏により収納部Cを格納位置とこの格納位置の前方下部へ引出した取出し位置との間で昇降できるように支持するのに、平行リンク1、2が、図7(a)に示すように垂直姿勢よりも後方側に傾斜した傾斜姿勢で収納部Cを格納位置に支持しているので、これだけで収納部Cの自重によって平行リンク1、2には後方への回転モーメントが働いていることにより、地震等にても収納部Cが平行リンク1、2を後方への傾斜姿勢から垂直姿勢に回動しながら不用意に持ち上がるようなことがないので使用の安全を図ることができる。
【0033】
その上、この後方への傾斜姿勢から垂直姿勢の直前またはほぼ垂直姿勢になる位置まで、平行リンク1、2のリンク1bを枢支しかつこれに同体回転する枢軸7とギヤ26aとの間に遊びSSを持っていることにより、格納位置の収納部Cを平行リンク1、2が図8(a)に示す垂直姿勢直前ないしはほぼ垂直姿勢になって、図8(b)に示すように遊びSSがなくなるまでは、ダンパー機構11の蔓巻きばね21が働かないのは勿論、ダンパ機構11のロータリダンパ22による抵抗なしに軽快に引き出すことができるので使用し易いし、地震等による揺れが大きく万一平行リンク1、2が前記垂直姿勢の直前またはほぼ垂直姿勢に達した以降は、通常の場合同様にダンパー機構11のロータリダンパ22が働くので、前記遊びSSによる弊害は特にない。
【0034】
【発明の効果】
本発明の請求項1の発明は、収納部の速度を抑制するダンパー手段を備えているので、収納物品の重量が支持手段収納部の下降速度を増速させるように働いてもこれをダンパー手段が抑制するので、収納部を低速度で安全に下降させられるという効果が得られる。また、収納部の下降動作でチャージされる複数のばねを選択的に働かせることができる。
【0035】
また、請求項2の発明は、収納ボード内に上記のような収納部用昇降支持ユニットを収容して、取り付け基台を収納ボードに取り付け、平行リンクの自由端部側に収納部を支持する簡単な組み立て作業だけで、通常時は収納部を収納ボードに格納された状態とし、収納部に物品を出し入れするときに収納部を収納ボードの前方下部に引出し下降させた取り出し位置とする昇降収納装置とすることができる。

[Industrial applications]
The present invention relates to an elevating support unit for a storage unit used to store various items in a kitchen or the like and an elevating storage device using the same .
[0002]
[Prior art]
Such a storage unit lifting support unit and a lifting storage device using the same are known from JP-A-61-154610 and the like.
[0003]
This supports the storage section between the free ends of the parallel links on both sides individually pivotally supported on the inner surfaces of both sides of the storage board, and pulls the storage section down to the storage position on the storage board and the front lower part of the storage board. It can be moved up and down with the taken-out position. By using a tension spring between the link and the fixed part, the link pair can lower the storage part at a low speed, and the storage part is in the storage position with the parallel link inclined backward from the vertical position. By supporting it, it is possible to prevent it from inadvertently protruding forward even in the event of an earthquake or the like and dropping to the take-out position, thereby ensuring safety in use.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, since the lowering speed of the storage section is limited only by operating the tension spring between the link and the fixed section, if the weight of the storage section and the object stored therein is large, Since a sufficient damper function cannot be exerted unless a strong and long spring is used, the parallel link is greatly inclined forward when the storage unit is lowered to the take-out position, so that the weight of the storage unit increases the descent speed. Until it works, the resistance becomes too large, making it difficult to use.
[0005]
In addition, although the use of safety can be achieved by supporting the storage unit in the storage position in the inclined position in which the parallel link is tilted backward from the vertical position, the extension spring moves the parallel link from the inclined position in which the parallel link is tilted backward. It works as a damper in the whole process of lowering to the take-out position after raising it in the vertical position. In addition to the fact that a large force is required to start moving a stationary heavy object, the initial operation when pulling out the storage part to the extraction position and lowering it is heavy, which is inconvenient to use. Has become.
[0006]
An object of the present invention is to solve such a problem, and an object of the present invention is to provide an ascending / descending support unit for an accommodating portion which ensures sufficient safety and is convenient for use, and an ascending / descending accommodating device using the same. Things.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a storage unit lifting support unit of the present invention includes a support means pivotally supported on a mounting base so as to raise and lower the storage unit, and a damper for suppressing the speed of the storage unit. Means, and a plurality of springs charged by the lowering operation of the storage section , wherein the springs can be selectively operated .
[0008]
[Action]
Since the storage unit lifting and lowering support unit of the present invention includes damper means for suppressing the speed of the storage unit, even if the weight of the stored article acts to increase the descent speed of the support means storage unit, the damper means can reduce the speed of the storage unit. Since the means is restrained, the storage section is safely lowered at a low speed. Further, a plurality of springs charged by the lowering operation of the storage section can be selectively operated.
[0009]
【Example】
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of a storage unit lifting support unit and a lifting storage device using the same according to the present invention will be described below with reference to FIGS.
[0010]
1 to 6 show a first embodiment of the present invention. This embodiment shows a case of a storage device in which a storage unit elevating support unit A is stored in a storage board B as shown in FIGS. 1 to 3 and a cage type storage unit C is supported so as to be able to move up and down. I have.
[0011]
As shown in FIGS. 4 to 6, the storage unit elevating and lowering support unit A separately pivots the parallel links 1 and 2 on both sides supporting the storage unit C between the free ends to the left and right mounting bases 3 and 4, respectively. The pivots 5 and 6 which support and support the front links 1a and 2a of the opposite parallel links 1 and 2 on both sides and which rotate in the same direction are connected and integrated by a coupling shaft 17. Thereby, the mounting bases 3 and 4 are integrated, and the parallel links 1 and 2 on both sides are linked.
[0012]
Therefore, since the parallel links 1 and 2 on both sides pivotally supported by the mounting bases 3 and 4 constitute a unitized lifting support unit A for a storage unit, the entire unit is handled as one unit, and each mounting base is handled as one unit. 3 and 4 can be easily attached to the inner surfaces on both sides of the storage board B with the screws 10 or the like without requiring any special alignment work between them. When the pivots 7, 8 of the rear links 1b, 2b are also connected and integrated, the rigidity of integration of the mounting bases 3, 4 and the interlocking rigidity of the parallel links 1, 2 on both sides can be further increased.
[0013]
The parallel links 1 and 2 are connected between the free ends of the front and rear links 1a and 1b and between the free ends of the links 2a and 2b by the mounting seats 1c and 2c for mounting the storage section C. In a state in which C is not supported, a complete parallel link on the storage unit elevating support unit A side is formed. Therefore, in order to support the storage portion C between the free ends of the parallel links 1 and 2, the mounting seats 1c and 2c may be mounted on the both side plates 9 of the storage portion C with screws 10.
[0014]
Due to such an assembling structure, the storage device of the present embodiment in which the storage unit lifting support unit A is stored in the storage board B and the storage unit C is supported so as to be able to move up and down can be assembled easily and quickly with a small number of work steps. . The storage section C supported by the storage section elevating and lowering support unit A in the storage board B is stored by the parallel links 1 and 2 on both sides being raised and lowered on the mounting bases 3 and 4 around the pivots 5 to 8. The storage board is moved up and down between a storage position located in the board B as shown in FIGS. 1 and 2 and a take-out position in which the storage board B is pulled out and lowered as shown in FIG.
[0015]
Further, since the parallel links 1 and 2 on both sides cooperate with each other, there is no difference in the support and movement of the storage portion C by the parallel links 1 and 2 on both sides, and between the free ends of the parallel links 1 and 2 on both sides. Even if the storage section C supported by the storage section C is a simple and low-rigid one such as the cage type shown in the drawing, the storage section C exhibits sufficient support rigidity to prevent the storage section C from being twisted or shaken. It can be lightweight and small.
[0016]
On the other hand, between the pivots 7, 8 pivotally supporting the links 1b, 2b on the rear side of the parallel links 1, 2 and rotating together with the links 1 and 2 and the mounting bases 3, 4, the accommodating portions of the parallel links 1, 2 are provided. The damper mechanisms 11 and 12 for limiting the speed at which C is lowered to the take-out position are operated. Even if the damper mechanisms 11 and 12 are operated only on one of the pivots 7 and 8, the parallel links 1 and 2 on both sides are interlocked, so that they can be equally operated on both. Even if the two damper mechanisms 11 and 12 are shared and operated as described above, they can be equally applied to the parallel links 1 and 2 on both sides regardless of whether they are of the same type.
[0017]
The damper mechanisms 11 and 12 are accommodated and operated in the spaces between the mounting seats 3a and 4a where both ends of the mounting bases 3 and 4 are bent outward, and are operated between the mounting seats 3a and 4a. It is equipped using a mounting plate 20 which is welded across.
[0018]
The damper mechanisms 11 and 12 are operated by using the rotation of the pivots 7 and 8, and are mounted on the support structure of the links 1a and 2b separated from the links 1a and 2b, and use the rotation of the pivots 5 and 8. And can be provided compactly.
[0019]
Specifically, one damper mechanism 11 operates a spiral spring 21 and a rotary oil damper 22, and the other damper mechanism 12 operates only a spiral spring 31.
[0020]
The helical spring 21 of the damper mechanism 11 is wound around a portion of the pivot 7 protruding inside the mounting plate 20, and one end 21 a of the pivot shaft 21 is attached to the inside of the mounting plate 20 as shown in FIGS. The other end 21b is received by a locking member 25 welded to the side surface, and the other end 21b is mounted on a large-diameter gear 26 mounted to rotate about the pivot 5 between the mounting plate 20 and the mounting base 3. The push pin 24 attached to any one of the plurality of attachment holes 23 is opposed with play S.
[0021]
As a result, when the gear 26 rotates in conjunction with the operation in which the parallel links 1 and 2 fall down in the direction of the arrow shown in FIG. The play S is merely approached to the end 21b of the coil spring 21 but at a predetermined intermediate position where the inclination of the parallel links 1 and 2 increases and the weight of the storage section C increases the downward movement speed. After that, the end 21b is pushed and thereafter, the spiral spring 21 is gradually charged between the end 21a and the one end 21a received by the locking member 25, and the weight of the storage portion C is reduced. Even if the descending speed is increased, the influence is reduced by the resistance during the charging operation, so that the parallel links 1 and 2 can descend at a low speed.
[0022]
The oil damper 22 is mounted on the inner surface of the mounting plate 20. The pinion gear 27 mounted on the rotary shaft 22a shown in FIG. 6 meshes with the gear 26, and the rotation of the pivot 7 when the parallel links 1 and 2 fall down increases. The rotation is transmitted to the rotating shaft 22a at a high speed.
[0023]
Therefore, the relative speed between the rotating blade 22b attached to the rotating shaft 22a and the braking blade 22c in the oil damper 22 is increased, and the rotational resistance of the rotating blade 22b due to the oil sealed in the oil damper 22 is increased. Thus, the pulling speed from the position where the parallel links 1 and 2 start to fall down from the standing state to the position where the spiral spring 21 starts to work can be sufficiently limited with a small damper capacity.
[0024]
The helical spring 31 of the other damper mechanism 12 is provided substantially in the same manner as the helical spring 21 by the pivot 8 and a rotating disk 32 mounted on the pivot 8 instead of the gear 26. The difference from the case of the spiral spring 21 is that one end 31a of the spiral spring 31 is received by a locking bolt 33 screwed to the mounting plate 20.
[0025]
By rotating the locking bolt 33, the locking bolt 33 can be advanced to a position facing the end portion 31a or can be retracted from the facing position. By setting the locking bolt 33 to the retracted position, even if the other end 31b of the helical spring 31 is pushed toward the one end 31a by the pushing pin 24 on the turntable 32, this end 31b may be pushed. Since the locking bolt 33 does not receive the spring 31a, the spiral spring 31 is only idled around the pivot 8, and does not exert a damper function on the parallel links 1 and 2. However, when the end portion 31b of the spiral spring 31 is pushed toward the end portion 31a by the pushing pin 24 by setting the locking bolt 33 to the advanced position, the locking bolt 33 is moved to the end portion 31a. Since the spiral spring 31 is received and not released, the spiral spring 31 is charged between both ends 31a and 31b, and exerts a damper function on the parallel links 1 and 2 like the spiral spring 21.
[0026]
Thus, when the locking bolt 33 is moved forward and backward to activate or deactivate the damper mechanism 12, the damper function can be enhanced or weakened in accordance with the weight of what is stored in the storage section C. However, a plurality of such spiral springs can be mounted on the same pivot and selectively operated.
[0027]
The gear 26 is provided with an arc-shaped long hole 26a through which a stopper pin 34 firmly mounted between the mounting base 3 and the mounting plate 20 passes. At the position of the parallel links 1 and 2 where the storage section C descends to the take-out position, the end of the elongated hole 26a abuts against the stopper pin 34 to prevent the parallel links 1 and 2 from rotating further downward. . This prevents the storage section C from being excessively lowered beyond the predetermined take-out position.
[0028]
The connecting shaft 17 connecting the pivots 5 and 6 is, for example, a pipe member as shown in the figure, and is fitted to the ends 5a and 6a protruding from the mounting bases 3 and 4 of the pivots 5 and 6 and fixed by screws 35. The connecting shafts 17 having different lengths can be selectively used or replaced. Accordingly, it is possible to support the storage boards B having different lateral sizes and support the storage section C having a size suitable for the storage boards B so as to be able to move up and down. A handle 9a for elevating operation is mounted between the lower front portions of both side plates 9 of the storage section C.
[0029]
On the inner surface on both sides of the storage board B, screw holes 36 for mounting the respective mounting bases 3 and 4 are provided in multiple stages, and the storage section C of the storage section lifting support unit A with respect to the height of the storage board B is provided. In the case where the height is higher than the total height in a state where is supported, the mounting height of the storage unit elevating support unit A to the storage board B can be freely changed according to the height of the user's back.
[0030]
FIGS. 7 and 8 show a lowering damper device for a lifting storage unit as a second embodiment of the present invention. In the present embodiment, the storage unit C is supported and stored so as to be able to move up and down between a storage position and a take-out position pulled out to the lower front part of the storage position by the undulating parallel links 1 and 2 of the storage unit lifting support unit A. The second embodiment is common to the first embodiment in that a damper mechanism 11 for accommodating and attaching to the board B and restricting the descending speed of the accommodating portion C is operated.
[0031]
In this embodiment, in particular, as shown in FIG. 7A, the parallel link 1 supports the storage section C at the storage position in an inclined posture inclined rearward from the vertical posture, and from this inclined posture, FIG. A play is provided between the damper mechanism 11 immediately before the vertical posture shown in FIG. Specifically, as shown in FIG. 7B, a play SS of a predetermined rotation range is provided between the gear 26 and the pivot 7 of the rotary damper 22 of the damper mechanism 11.
[0032]
Accordingly, the parallel links 1 and 2 support the storage section C so that the storage section C can be moved up and down between the storage position and the take-out position pulled out to the lower front part of the storage position by the undulation of the parallel links 1 and 2. As shown in FIG. 7 (a), the storage portion C is supported at the storage position in an inclined position inclined rearward from the vertical position, so that the parallel links 1 and 2 are moved rearward by the weight of the storage portion C alone. Because the rotating moment of the storage unit C does not cause the storage unit C to be inadvertently lifted while rotating the parallel links 1 and 2 from the backward inclined posture to the vertical posture even in the event of an earthquake, etc. Safety can be achieved.
[0033]
In addition, from the rearward inclined posture to a position immediately before the vertical posture or a position where the vertical posture becomes substantially vertical, the link 1b of the parallel links 1 and 2 is pivotally supported and the gear 26a rotates between the pivot 7 and the gear 26a. By having the play SS, the parallel links 1 and 2 of the storage portion C at the storage position are brought to a position immediately before or almost vertical to the vertical posture shown in FIG. 8A, and play is performed as shown in FIG. Until SS disappears, not only the spiral spring 21 of the damper mechanism 11 does not work but also the damper mechanism 11 can be pulled out lightly without resistance by the rotary damper 22. In the unlikely event that the parallel links 1 and 2 have just reached the vertical position or have reached almost the vertical position, the rotary damper 22 of the damper mechanism 11 operates in the same manner as in the normal case. Harm is not particularly.
[0034]
【The invention's effect】
Since the invention of claim 1 of the present invention includes the damper means for suppressing the speed of the storage part, even if the weight of the stored article acts to increase the descent speed of the support means storage part, the weight of the storage article is reduced by the damper means. Therefore, an effect is obtained that the storage section can be safely lowered at a low speed. Further, a plurality of springs charged by the lowering operation of the storage section can be selectively operated.
[0035]
According to a second aspect of the present invention, the storage unit lifting support unit is housed in the storage board, the mounting base is attached to the storage board, and the storage unit is supported on the free end side of the parallel link. With only simple assembly work, the storage part is usually stored in the storage board, and the storage part is pulled out and lowered to the lower front part of the storage board when articles are put in and out of the storage part. It can be a device.
