Description

本発明は扉付き昇降キャビネットに係り、特に扉の開閉動作を改良した扉付き昇降キャビネットに関する。   The present invention relates to a lifting cabinet with a door, and more particularly, to a lifting cabinet with a door that improves the opening and closing operation of the door.

従来、この種の扉付き昇降キャビネットとして、扉が設けられた外箱に内箱をモータにより昇降可能に設け、内箱の下降時にその内箱の前面が外箱から全体的に表出し得る如く構成し、内箱の上昇収納時にその内箱の前面を覆う扉は、外箱に連結したヒンジを介して上端を支点として下端側を前後方向に回動し得る構成としたものが知られている。   Conventionally, as this type of elevator cabinet with a door, an inner box is provided in an outer box provided with a door so that it can be raised and lowered by a motor, and when the inner box is lowered, the front of the inner box can be exposed from the outer box as a whole. It is known that the door which covers the front of the inner box when the inner box is raised and stored can be rotated in the front-rear direction with the upper end as a fulcrum via a hinge connected to the outer box. Yes.

このような構成のものでは、内箱の昇降時に扉と前方突出状態の収納物とが干渉する危険を防止する手段が必要である。例えば食器乾燥機に適用した場合、扉の開度が不十分で、かつ内箱に収納した食器が前方に飛出している状態で内箱を上昇させると、食器が扉に衝突して破損する危険がある。   With such a configuration, means for preventing the danger of interference between the door and the stored item in the forward projecting state when the inner box is raised and lowered is necessary. For example, when applied to a tableware dryer, if the inner box is raised while the opening of the door is insufficient and the tableware stored in the inner box is protruding forward, the tableware will hit the door and break. There is danger.

そのため、外箱は内箱の上昇収納時にその内箱の前面を覆う扉を有し、この扉は外箱に連結したヒンジを介して上端を支点として下端側を前後方向に回動し得る構成とし、さらに、扉と内箱とを複数のアームよりなるリンクによって連結し、扉が内箱の昇降に伴ってその上昇時には閉方向に、かつ下降時には開方向にそれぞれ回動できる構成とし、リンクは、内箱の上昇ストロークの途中位置で扉を最大開き角度位置で停止させる構成とした扉付き昇降キャビネットが提案されている（特許文献１）。 Therefore, the outer box has a door that covers the front surface of the inner box when the inner box is raised and stored, and the door can be rotated in the front-rear direction with the upper end as a fulcrum through a hinge connected to the outer box. In addition, the door and the inner box are connected by a link composed of a plurality of arms, and the door can be rotated in the closing direction when the inner box is raised and lowered, and in the opening direction when lowered, the link. Has proposed a lifting cabinet with a door configured to stop the door at the maximum opening angle position in the middle of the rising stroke of the inner box ( Patent Document 1 ).

しかし、特許文献１のものは、内箱への収納物の出し入れ動作に扉の開き時の扉下部が前方へ大きく張出しているので邪魔になる。特に上部にある収納物の出し入れ動作には大きく開かないと見にくいなどの使い勝手の悪さがあり、改良の余地がある。 However, the thing of patent document 1 gets in the way because the lower part of the door when the door is opened largely projects forward in the taking in and out operation of the stored items in the inner box. In particular, there is room for improvement in the operation of putting in and out the stored items in the upper part because it is difficult to see unless it is opened wide.

なお、特許文献２には、垂直状態を保ったまま開閉する扉に連動して、内箱を昇降させる昇降式収納装置が提案されているが、この装置は人手により扉を開閉し、内箱を昇降させるために重量のある収納物を収納するのに適さず、また、昇降が人手によるため装置を高所に設置するのに適さず、さらに、昇降棚の昇降に用いられる昇降ガイド機構が多数のリンク部材で構成されているため、モータによる内箱の昇降機構には適さない。
特開２００２−９５５３４号公報 特開２００４−１６７２０号公報 Patent Document 2 proposes a lifting and lowering storage device that raises and lowers the inner box in conjunction with a door that opens and closes while maintaining a vertical state. This device manually opens and closes the door, It is not suitable for storing heavy items to lift and lower, and is not suitable for installing the device at a high place because it is manually moved up and down, and there is a lifting guide mechanism used for lifting and lowering the lifting shelf. Since it is composed of a large number of link members, it is not suitable for an inner box lifting mechanism by a motor.

上記のように、扉は閉じ動作はその自重を利用したアーム構成としたので、構造が簡単であり、容易に扉の開閉を行なうことができる。   As described above, since the door is closed by an arm configuration using its own weight, the structure is simple and the door can be easily opened and closed.

図９乃至図１１は外箱２の一部を構成し、扉５の上部に設けられる前板２ｂの取付け状態を示すもので、この前板２ｂは予め取り付けられた前板止め具２ｂ２を、外箱２の側面２ｃに取り付けられた前板止め具受２ｂ３に係合させて仮止めし、この前板止め具受２ｂ３と前板止め具２ｂ２を螺着して、外箱２に取り付けるようになっている。これにより、組立が容易で特に昇降機構のメンテナンスの際などに前板を取り外し取り付ける作業が必要となるが、前板が前方から仮止めできるので一人でも簡単に行える。 FIG. 9 to FIG. 11 constitute a part of the outer box 2 and show a mounting state of the front plate 2b provided on the upper portion of the door 5, and this front plate 2b has a front plate stopper 2b 2 attached in advance. The front plate stopper receiver 2b 3 attached to the side surface 2c of the outer box 2 is engaged and temporarily fixed, and the front plate stopper receiver 2b 3 and the front plate stopper 2b 2 are screwed together to form the outer box. 2 is attached. As a result, the assembly is easy, and it is necessary to remove and attach the front plate particularly during maintenance of the lifting mechanism. However, since the front plate can be temporarily fixed from the front, it can be easily performed by one person.

また、本発明に係る昇降式食器収納キャビネットの使用方法について説明する。   Moreover, the usage method of the raising / lowering type tableware storage cabinet based on this invention is demonstrated.

図４及び図５に示すように、使用者は、食器類の出し入れを行なうために、外箱２内に収容された状態の内箱３を降下させ、内箱３を外箱２から全体的に表出させる。   As shown in FIGS. 4 and 5, the user lowers the inner box 3 accommodated in the outer box 2 and removes the inner box 3 from the outer box 2 in order to put in and out dishes. Make it appear.

この内箱３の降下は、操作レバー４ｉ、制御装置４ｊを介してモータ４ａを駆動させて、巻き取りドラム４ｄを回転させ、ベルト４ｂを送り出し、主として内箱３の重量により行なわれる。   The lowering of the inner box 3 is mainly performed by the weight of the inner box 3 by driving the motor 4a via the operation lever 4i and the control device 4j, rotating the winding drum 4d, and feeding out the belt 4b.

図７および図８に示すように、内箱３の降下に伴って、内箱３の側板３ｃに取り付けられ、作動アーム６１ｂの変曲点ｐ１に当接している作動ローラ６１ａも降下し、変曲点ｐ２に達する迄の傾斜部６１ａ２に当接している間、作動ローラ６１ａは作動アーム６１ｂをスプリング６１ｂ４に抗して図中時計周り方向に回動させる。 As shown in FIGS. 7 and 8, along with the descent of the inner box 3 is attached to the side plate 3c of the inner box 3, also drops actuator roller 61a which is in contact with the inflection point p 1 of the working arm 61b, while the inclined portion 61a 2 until reaching the inflection point p 2 are in contact, the actuator roller 61a causes the figure rotates in the clockwise direction against the actuating arm 61b of the spring 61b 4.

この作動アーム６１ｂの回動に伴い、開閉アーム機構６２はフォーバーリンケージの動きをなし、第１の開閉用アーム６２ａおよび第２の開閉用アーム６２ｂが外箱２に取り付けた支点を中心に回動して、扉５はわずかな傾斜状態を保ったまま移動（回動）させ、下端部５ａを上昇させるように移動させる。   As the operating arm 61b rotates, the open / close arm mechanism 62 moves in a forver linkage, and the first open / close arm 62a and the second open / close arm 62b rotate around a fulcrum attached to the outer box 2. The door 5 is moved (rotated) while maintaining a slight inclination, and the lower end 5a is moved up.

さらに、内箱３は降下するが、作動アーム６１ｂには変曲点ｐ２から端部近傍の点ｐ３間の垂直部６１ｂ３では、作動ローラ６１ａは作動アーム６１ｂに当接しているが、これをさらに時計まわり方向に押圧することがなく、上記傾斜部６１ｂ２間での回動以上の作動アーム６１ｂの回動はなく、従って、開閉アーム機構６２の回動もなく、扉５は作動ローラ６１ａが変曲点ｐ２にあるときの、開放状態を保つ。 Furthermore, although the inner box 3 drops, the vertical portion 61b 3 between the points p 3 near the end of the inflection point p 2 is the operating arm 61b, but the actuator roller 61a is in contact with the actuating arm 61b, This further without pressing in the clockwise direction, rather than the rotation of the rotating or more actuating arm 61b in between the inclined portion 61b 2, therefore, no rotation of the closing arm mechanism 62, the door 5 is actuated when the roller 61a is in the inflection point p 2, it keeps the open state.

このように、内箱３が下降範囲の全体の途中、例えば１／３位まで下降したとき、扉５が設定全開状態になるので、受具８上の食器類は内箱３を最下端まで下降させなくても出し入れ可能である。   Thus, when the inner box 3 is lowered to the middle of the entire lowering range, for example, to 1/3, the door 5 is in the fully opened state, so that the tableware on the receiver 8 moves the inner box 3 to the lowest end. It can be taken in and out without being lowered.

図２および図３に示すように、作動ローラ６１ａが点ｐ３に達すると、内箱３の降下は完了し、内箱３はその前面が外箱２から全体的に表出する。 As shown in FIGS. 2 and 3, when the operating roller 61 a reaches the point p 3 , the lowering of the inner box 3 is completed, and the front surface of the inner box 3 is entirely exposed from the outer box 2.

このように扉５がわずかな傾斜状態でかつ扉５の下端部５ａが上昇した状態で、使用者は受具８と食器類の出し入れを行なう。従って、食器類の出し入れ時、扉５の下端部５ａが前方へ大きく張出していないので邪魔にならず、さらに、内箱３の上部にある食器類等をよく見ることができて使い勝手のよい。   In this way, with the door 5 in a slightly inclined state and the lower end portion 5a of the door 5 raised, the user takes in and out the receiving tool 8 and tableware. Therefore, when the tableware is taken in and out, the lower end portion 5a of the door 5 does not protrude greatly forward, so that it does not get in the way.

食器類の出し入れ完了後、再び、操作レバー４ｉ、制御装置４ｊを介してモータ４ａを駆動させて、巻き取りドラム４ｄを回転させ、ベルト４ｂを巻き取り、内箱３を上昇させる。   After completion of taking in and out of the tableware, the motor 4a is again driven through the operation lever 4i and the control device 4j, the take-up drum 4d is rotated, the belt 4b is taken up, and the inner box 3 is raised.

この上昇過程において、図７に点線で示すように、作動アーム６１ｂのｐ１点で当接する作動ローラ６１ａは、内箱３の上昇に伴って、垂直部６１ｂ３に沿って上昇する。このとき、作動アーム６１ｂはそのままの状態を保つので、開閉アーム機構６２は作動せず、扉５も開放状態を保つ。従って、扉５と前方突出状態の食器類等の収納物とが干渉することがなく、危険の防止が図れるとともに、作動ローラ６１ａと作動用アーム６１ｂが非拘束状態で当接しているので、内箱３の奥行きよりも長い収納物が収納された場合にも、収納物に押されて開閉アーム機構６２と扉５が動き、干渉が緩和され安全である。 In the ascending process, as indicated by a dotted line in FIG. 7, the operating roller 61 a that contacts at the point p 1 of the operating arm 61 b rises along the vertical portion 61 b 3 as the inner box 3 rises. At this time, since the operating arm 61b is kept as it is, the opening / closing arm mechanism 62 is not operated, and the door 5 is also kept open. Therefore, there is no interference between the door 5 and stored items such as tableware in the forward projecting state, danger can be prevented, and the operating roller 61a and the operating arm 61b are in contact with each other in an unconstrained state. Even when a stored item longer than the depth of the box 3 is stored, the open / close arm mechanism 62 and the door 5 are moved by the stored item and the interference is mitigated, which is safe.

さらに、内箱３が上昇して作動ローラ６１ａも上昇するが、作動ローラ６１ａが端部近傍の点ｐ３から変曲点ｐ２間にあるときは、作動アーム６１ｂを反時計回り方向に回動させることなく、開閉アーム機構６２、扉５の回動もなく、扉５は開放状態を保つ。 Further, the inner is box 3 increases also the actuator roller 61a rises, when the actuator roller 61a is in between the inflection point p 2 from the point p 3 in the vicinity of the end portion, turn the actuating arm 61b in the counterclockwise direction Without being moved, the opening / closing arm mechanism 62 and the door 5 are not rotated, and the door 5 is kept open.

このように、内箱３が上昇範囲の全体の途中まで上昇したとき、食器類が内箱３から前方に突出していても、内方に押し込むことができる。   In this way, when the inner box 3 rises to the middle of the entire ascending range, the tableware can be pushed inward even if it protrudes forward from the inner box 3.

内箱３が上昇を継続して、作動ローラ６１ａが上昇し変曲点ｐ２を過ぎ、傾斜部６１ａ２に達すると、作動アーム６１ｂが反時計回り方向に回動し、開閉アーム機構６２が作動して扉５はその自重により反時計周り方向に回動しながら閉じていき、内箱３の上昇が完了して、内箱３の収納が完了すると、作動ローラ６１ａは変曲点ｐ１に達し、扉５は開口を完全に閉塞し、この状態を保つ。 The inner box 3 continues to rise, past the actuator roller 61a is elevated inflection point p 2, reaches the inclined portion 61a 2, operating arm 61b is rotated in the counterclockwise direction, the opening and closing arm mechanism 62 The door 5 is actuated and closed while rotating counterclockwise by its own weight, and when the inner box 3 is lifted and the inner box 3 is stored, the operating roller 61a is moved to the inflection point p1. The door 5 completely closes the opening and maintains this state.

上記のように、内箱３の昇降はモータ４ａによって行なわれるので、内箱３に重量のある収納物が収納されていてもその昇降が容易であり、また、高所に設置するのに適し、さらに、内箱３を昇降する昇降機構４をモータ４ａとベルト４ｂで構成したので、電動に適し、構造が簡単で耐久性もある。   As described above, since the inner box 3 is moved up and down by the motor 4a, the inner box 3 can be easily moved up and down even when a heavy storage item is stored in the inner box 3, and is suitable for installation in a high place. Furthermore, since the elevating mechanism 4 that elevates and lowers the inner box 3 is constituted by the motor 4a and the belt 4b, it is suitable for electric operation, has a simple structure, and is durable.

上記のように、本実施形態によれば、モータによる内箱の昇降が可能で、内箱への収納物の出し入れ時、扉が邪魔にならず、さらに、内箱の上部にある収納物をよく見ることができ使い勝手のよい扉付き昇降キャビネットが実現される。   As described above, according to the present embodiment, the inner box can be moved up and down by a motor, the door does not get in the way when the stored item is put in and out of the inner box, and the stored item at the upper part of the inner box is further removed. An elevator cabinet with a door that can be seen well and is easy to use is realized.
