Description

【０００１】
【発明の属する技術分野】
本発明は、段ボールを使用したキャビネットにかかり、特に積み重ね時の筐体強度を補強する部材を筐体を構成する段ボールによって巻いた状態で配することで安全性と見栄えの向上を図ることができる段ボール製キャビネットに関するものである。
【０００２】
【従来の技術】
従来、筐体が段ボールでなり、この筐体を複数積み重ねてキャビネットとする段ボール製キャビネットが種々知られている。この段ボール製キャビネットは、積み重ねて書類などを収納した際における筐体の強度を補強するために、例えばその上端部に連結凹部を、その下端部に連結凸部を、その縦方向の中央部位に横方向の連結孔を各々形成した金属製の補強部材を筐体の両側面の縦方向に露出して設けている。
【０００３】
上記補強部材は、ある筐体の上端部の連結凹部に対し、該筐体の上部に積み重ねた他の筐体の下端部の連結凸部を嵌入して、縦方向の連結を行い、横方向に隣接した連結孔に雌ねじと雄ねじを嵌入して、横方向の連結を行う。このようにして段ボール製キャビネットは、筐体の縦方向及び横方向の連結を行うと共に筐体強度を補強するようにしている。なお、この種の段ボール製キャビネットにおける補強部材を用いた筐体の補強は、各種補強部材の形状や材質及び連結方法が異なるもののほぼ必須の条件となっている。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来の段ボール製キャビネットは、筐体を補強すべく硬質な例えば金属製の補強部材が筐体の外壁両側面に露出していたために、筐体に衝突した際には大きなけがをしたりする虞があり、また、段ボールの統一性を欠いて美観が損なわれるといった不具合があった。また、従来の段ボール製キャビネットは、補強部材が筐体の外壁総側面に露出しているために、金属製の補強部材では錆びが生じ易く、また、又硬質のプラスティック製の補強部材では埃が付着し易いといった問題があった。
【０００５】
本発明は、上記した不具合を解消するために成されたものであり、筐体に衝突してけがをする危険性を低減できると共に、段ボールで外観を統一することができ、さらに、補強部材が容易に錆びたり埃が付着することのない段ボール製キャビネットを提供することを目的としている。
【０００６】
【課題を解決するための手段】
上記した目的を達成するために、本発明の段ボール製キャビネットは、縦連結凹部と横方向連結孔と突出部とがそれぞれ形成された補強連結部材を、筐体の収納開口部における横方向の両側部の内壁に、段ボールに巻いた状態で配したのである。このように、補強連結部材が外面に露出しないので、該補強連結部材が容易に錆びたり埃が付着することがなくなる。
【０００７】
【発明の実施の形態】
本発明の段ボール製キャビネットは、書類等を収納する筐体を段ボールで形成し、この筐体を縦方向及び横方向に積み重ねて使用する段ボール製キャビネットであって、積み重ね時の筐体強度を補強するため、その縦方向両端部に各々形成された縦連結凹部と、その縦方向中央部位に形成された横方向連結孔及びその長尺側面の複数箇所に形成した突出部と、を有した補強連結部材を、前記筐体の収納開口部における横方向の両側部に段ボールに巻いた状態で配したものである。
【０００８】
また、本発明の段ボール製キャビネットは、上記構成における補強連結部材に代えて、つまり縦方向両端に縦連結凹部が形成されたものに代えて、その縦方向の一端部に縦連結凹部、他端部に縦連結凸部がそれぞれ形成されたものを用いてもよい。
【０００９】
さらに、本発明の段ボール製キャビネットは、上記したいずれかの構成において、補強連結部材による縦方向への連結を行うための補助具を有したものとしてもよい。
【００１０】
上記構成によれば、筐体を縦方向に例えば連結した状態で積み重ねるには、ある筐体の補強連結部材における例えば上端部の縦連結凹部に対して、該筐体の上部に積み重ねる補強連結部材の例えば下端部の縦方向連結凸部を嵌入して、又は連結用の補助具を、縦方向に隣接する縦方向連結凹部同士に嵌入しあるいは縦方向連結凸部を補助するように取り付けて行う。一方、筐体を横方向に積み重ねるには、隣接した筐体の補強連結部材における横方向連結孔同士を連通した状態で、例えば雄ねじと雌ねじとを挿通して行う。こうすることで、積み重ねた段ボール製の筐体は、縦方向及び横方向に自在に連結され、また、書類等を収納しても筐体の強度を保持することができる。
【００１１】
そして、補強連結部材は、筐体の収納開口部における横方向の内壁両側部に突出部を用いて、段ボールに巻かれた状態で配されているので、該補強連結部材が外部に露出しない。このようにすることにより、補強連結部材を、例えば金属製としても錆びにくく、また、例えば硬質なプラスティック製としても埃が付着しない。さらに、補強連結部材が段ボールに巻かれているので筐体に衝突しても段ボールが衝撃を緩衝するのでけがを防止でき、また、上記のように筐体を縦方向及び横方向に連結した際には、段ボールで統一され見栄えがよい。
【００１２】
【実施例】
以下、本発明の段ボール製キャビネットの実施例を図１〜図４を参照して説明する。
図１は、本発明の段ボール製キャビネットの概略構成を示す。図２は、補強連結部材を示す。図３は、本発明の段ボール製キャビネットにおける要部の詳細を示す。図４は、本発明の段ボール製キャビネットの連結状況を示す。
【００１３】
１は、書類等を収納する筐体１ａを段ボールで形成し、複数の筐体１ａを各々縦方向及び横方向に積み重ねて使用する段ボール製キャビネットであり、この筐体１ａは、６面のうち１面に収納開口部１ｂが形成され、この収納開口部１ｂに、引き出し１Ａが出し入れされる。
【００１４】
２は、収納開口部１ｂにおける横方向の内壁両側面に配された補強連結部材であり、この補強連結部材２は、上下２面の段ボールの奥行長さに対して余剰した収納開口部１ｂの両側面２面の開口縁部に形成された巻込片１ｃに、上下端部以外が巻かれている。なお、図３（ａ），（ｂ）には、巻込片１ｃと補強連結部材２との巻込構造を部分的に示す。
【００１５】
筐体１ａの巻込片１ｃによって補強連結部材２の巻き込むには、例えば、図２（ａ），（ｂ）に示すような補強連結部材２を使用する場合には、補強連結部材２の長尺側面の複数箇所に屈曲した鉤状の突出部２ｄ（後述）を形成して、この鉤状の突出部２ｄで巻込片１ｃを係合しつつ該巻込片１ｃを該補強連結部材２に巻くことで、容易でかつ確実に補強連結部材２を巻込片１ｃに巻き込むことができる。また、この他には、不図示ではあるが、巻込片１ｃあるいは補強連結部材２における互いの接触面に接着剤を塗布して巻込片１ｃでもって補強連結部材２を巻き込めばよい。
【００１６】
さらには、不図示ではあるが、補強連結部材２の長尺側面の複数箇所に折曲突出片を形成し、巻込片１ｃでもって補強連結部材２を巻き込んだ際に、該折曲突出片を該巻込片１ｃの巻込内側から外側へと突出させ、巻込片１ｃの巻込外側へ突出した状態の折曲突出片を折り曲げることで巻込片１ｃと係合させるようにしてもよい。
【００１７】
そして、補強連結部材２は、例えば図２（ａ），（ｂ）に示すように構成している。すなわち、図２（ａ）に示す補強連結部材２は、本発明の請求項２における構成であり、四角管の上端部を縦連結凹部２ａとし、さらに、その下端部に縦連結凸部２ｂを設け、その縦方向中央部位に横方向連結孔２ｃが形成されている。一方、図２（ｂ）に示す補強連結部材２は、断面凹型の上端部を縦連結凹部２ａとし、さらに、その下端部に縦連結凸部２ｂを設け、その縦方向中央部位に横方向連結孔２ｃが形成されている。また、補強連結部材２は、その長尺側面に複数の前述した突出部２ｄを形成している。
【００１８】
補強連結部材２は、材質を例えば金属製とすれば、縦方向に複数積み重ねて書類などを収納しても十分に強度が保たれる。また、ある程度の強度を保持することができると共に軽量化及び低コスト化を図るならば、補強連結部材２は、硬質のプラスティックを用いればよい。
【００１９】
なお、上記筐体１ａの横方向両側面には、横方向連結孔２ｃと連通する孔１ｄが形成されており、これら横方向連結孔２ｃと孔１ｄは、図３（ａ）に示すように、後述する段ボール製キャビネット１の組立時に雄ねじ３ａと雌ねじ３ｂとが嵌入される。
【００２０】
さらに、補強連結部材２を金属製とした場合には、表面にキレート化合物を含浸させたシートを貼着したり、キレート化合物を塗布したりすれば、錆びることを確実に防止することができる。この場合、キレート剤としては、ＥＤＴＡ（Ethylene Diamine Tetraacetic Acid ）、ＮＴＡ（Nitrilo Triacetic Acid）、ＨＥＤＴＡ（Hydroxyethyl Ethylene Diamine Triacetic Acid）、ＤＴＰＡ（Diethylene Triamine Pentaacetic Acid）、ＴＴＨＡ（Triethylene Tetramine Hexaacetic Acid ）、ＨＩＤＥ（Hydroxyethyl Imino Diacetic Acid）、ＤＨＥＧ（Dihydroxy Ethyl Glycine ）などを使用する。
【００２１】
また、補強連結部材２をプラスティック製とする場合には、十分な強度を確保するために、例えばポリカーボネートやＡＢＳ（アクリロニトリル・ブタジエン・スチレン）樹脂等を採用すればよい。
【００２２】
さらに、補強連結部材２の形状については、図２に示す例に限られず、例えば請求項１の構成によれば、上記縦連結凸部２ｂに代えて、その両端が縦連結凹部２ａ，２ａとされたものであってもよい。この場合、縦方向への連結は行わず、単に積み重ねた状態での使用となるが、段ボール製キャビネット１に収納した内容物の自重や段ボールの摩擦により、２段又は３段程度積み重ねても十分安定して使用可能である。
【００２３】
次に、本発明の段ボール製キャビネット１の使用例について説明する。
いま、ここでの説明に使用する補強連結部材２は請求項２によるものを採用する。例えば縦２個、横２個に積み上げて作成する場合、例えば、最下段に位置させるべき筐体１ａを載置した後、図４（ａ）に示すように、横に次列の筐体１ａを載置し、隣接する筐体１ａ，１ａにおける横方向連結孔２ｃに孔１ｄを介して雄ねじ３ａと雌ねじ３ｂとを嵌入して最下段の横方向２個を連結する。
【００２４】
なお、最下段の２個の筐体１ａにおいては、最両側部の縦連結凸部２ｂ，２ｂを、例えば、互いに接近するように折り曲げて、中央部の縦連結凸部２ｂ，２ｂは互いに接触しないように各々折り曲げれば、これら折り曲げた縦連結凸部２ｂ，２ｂ，２ｂ，２ｂが、段ボール製キャビネット１の外形から露出することがない。
【００２５】
この後、最下段の筐体１ａ，１ａの上部に、２段目の２個の筐体１ａ，１ａを載置する。この縦方向への連結は、図４（ｂ）に示すように、下段の縦連結凹部２ａに上段の縦連結凸部２ｂを各々嵌入して行う。そして、上段の２個の筐体１ａにおいて横方向の連結を行い、引き出し１Ａを収納開口部１ｂから挿入すれば段ボール製キャビネット１が完成する。
【００２６】
以上のようにして完成した段ボール製キャビネット１においては、補強連結部材２が外部に露出することがないので、段ボール製キャビネット１に衝突しても、補強連結部材２を巻いた巻込片１ｃが、衝撃緩衝材として作用するので大きなけがを負うことがなく、また、補強連結部材２が外部に露出していないので、該補強連結部材２が金属製であっても錆びにくく、また硬質のプラスティック製であっても埃が付着しにくい。さらに段ボール製キャビネット１は、外形に、隙間や突出部が形成されないので隙間なくきちんと整列し、段ボールで統一されているのでシンプルで見栄えもよい。
【００２７】
また、上記では、請求項２の補強連結部材２を用いた連結手順を示したが、例えば、請求項１による補強連結部材２（両端に縦連結凹部２ａ，２ａが形成されている）を採用して縦方向に多段数積み重ねるには、請求項３による補助具を、上段に位置する補強連結部材２の下端の縦連結凹部２ａ、及び下段に位置する補強連結部材２の上端の縦連結凹部２ａに補助具を嵌入して順次連結すれば、安定して多段数積み重ねることができる。
【００２８】
また、請求項２の補強連結部材２を用いた場合においても、請求項３による補助具を使用して有効であり、すなわち、下段に位置する補強連結部材２の上端の縦連結凹部２ａに対して、上段に位置する補強連結部材２の下端の縦連結凸部２ｂ及び縦連結凸部２ｂに取り付けた請求項３による補助具を嵌入すれば、この連結箇所が補強され、より一層安定して積み上げることができる。
【００２９】
さらに、本発明の段ボール製キャビネット１は、上記実施例に限定されず種々の変形が可能である。例えば上記実施例での段ボール製キャビネット１は、筐体１ａを、縦連結凹部２ａが上端に縦連結凸部２ｂが下端に位置するようにして使用するようにしたが、この逆で縦方向の連結を行って組み立ててもよい。
【００３０】
【発明の効果】
以上説明したように、本発明の段ボール製キャビネットは、その縦方向両端部に縦連結凹部と、その縦方向中央部位に横方向連結孔及び突出部とがそれぞれ形成された補強連結部材を、筐体の収納開口部における横方向の両側部の内壁に、段ボールに巻いた状態で配したので、衝突しても大きなけがを負うことがなく、また、補強連結部材が外部に露出していないので、金属製の補強連結部材であっても錆びにくく、また硬質のプラスティック製であっても埃が付着しにくいと共に、外形に、隙間や突出部が形成されることがなく、段ボールで統一されているのでシンプルで見栄えもよく外観を損なうことはない。
【００３１】
また、本発明の段ボール製キャビネットは、上記の補強連結部材に代えて、その縦方向の一端部に縦連結凹部、他端部に縦連結凸部がそれぞれ形成したものとすれば、縦方向の連結を安定して行うことができる。
【００３２】
また、本発明の段ボール製キャビネットは、上記したいずれかの構成において、補強連結部材による縦方向への連結を行うための補助具を有したものとすれば、縦方向の連結がより一層安定して行え、多段数積み重ねて使用することができる。

FIG.
[0015]
In order to wind the reinforcing connecting member 2 by the winding piece 1c of the housing 1a, for example, when the reinforcing connecting member 2 as shown in FIGS. 2 (a) and 2 (b) is used, the length of the reinforcing connecting member 2 is increased. A hook-like protrusion 2d (described later) is formed at a plurality of locations on the side surface of the scale, and the winding piece 1c is engaged with the winding piece 1c by the hook-like protrusion 2d and the reinforcing connecting member 2 is engaged. By winding it around, the reinforcing connecting member 2 can be easily and reliably wound around the winding piece 1c. In addition to this, although not shown, it is only necessary to apply the adhesive to the contact surfaces of the winding piece 1c or the reinforcing connecting member 2 and wind the reinforcing connecting member 2 with the winding piece 1c.
[0016]
Furthermore, although not shown in the drawings, bent protruding pieces are formed at a plurality of locations on the long side surface of the reinforcing connecting member 2 and the reinforcing connecting member 2 is wound with the winding piece 1c. Is protruded from the inside of the winding piece 1c to the outside, and the bent protruding piece in a state of protruding to the outside of the winding piece 1c is bent to be engaged with the winding piece 1c. Good .
[0017]
And the reinforcement connection member 2 is comprised as shown, for example in FIG. 2 (a), (b). That is, the reinforcing connecting member 2 shown in FIG. 2 (a) has the structure according to claim 2 of the present invention, wherein the upper end portion of the square tube is the vertical connecting concave portion 2a, and the vertical connecting convex portion 2b is further provided at the lower end portion thereof. The horizontal direction connection hole 2c is formed in the vertical direction center site | part. On the other hand, the reinforcing connecting member 2 shown in FIG. 2 (b) has an upper end portion having a concave cross section as a vertical connecting concave portion 2a, further provided with a vertical connecting convex portion 2b at its lower end portion, and laterally connected to a central portion in the vertical direction. A hole 2c is formed. The reinforcing connecting member 2 has a plurality of the protruding portions 2d described above on its long side surface.
[0018]
If the material of the reinforcing connecting member 2 is, for example, metal, the strength is sufficiently maintained even when a plurality of documents are stacked in the vertical direction to store documents. Further, if it is possible to maintain a certain level of strength and reduce the weight and cost, the reinforcing connecting member 2 may be a hard plastic.
[0019]
Note that holes 1d communicating with the lateral coupling holes 2c are formed on both lateral sides of the casing 1a , and these lateral coupling holes 2c and 1d are formed as shown in FIG. The male screw 3a and the female screw 3b are inserted when the cardboard cabinet 1 described later is assembled.
[0020]
Furthermore, when the reinforcing connecting member 2 is made of metal, rusting can be reliably prevented by sticking a sheet impregnated with a chelate compound on the surface or applying a chelate compound. In this case, as the chelating agent, EDTA (Ethylene Diamine Tetraacetic Acid), NTA (Nitrilo Triacetic Acid), HETDA (Hydroxyethyl Ethylene Diamine Triacetic Acid), DTPA (Diethylene Triamine Pentaacetic Acid), TTHA (Triethylene Tetramine Hexaacetic Acid), HIDE ( Hydroxyethyl Imino Diacetic Acid), DHEG (Dihydroxy Ethyl Glycine), etc. are used.
[0021]
Further, when the reinforcing connecting member 2 is made of plastic, for example, polycarbonate, ABS (acrylonitrile butadiene styrene) resin or the like may be employed in order to ensure sufficient strength.
[0022]
Further, the shape of the reinforcing connecting member 2 is not limited to the example shown in FIG. 2. For example, according to the configuration of claim 1, instead of the vertical connecting convex portion 2 b, both ends thereof are connected to the vertical connecting concave portions 2 a and 2 a. It may be what was done. In this case, the connection in the vertical direction is not performed, and it is used in a stacked state. However, it is sufficient to stack two or three stages due to the weight of the contents stored in the cardboard cabinet 1 or the friction of the cardboard. It can be used stably.
[0023]
Next, a usage example of the cardboard cabinet 1 of the present invention will be described.
Now, the reinforcing connecting member 2 used in the description here adopts the one according to claim 2. For example, in the case of creating by stacking two vertically and two horizontally, for example, after placing the housing 1a to be positioned at the bottom, as shown in FIG. And the male screw 3a and the female screw 3b are fitted into the horizontal connecting holes 2c in the adjacent casings 1a and 1a through the holes 1d to connect the two lower horizontal components.
[0024]
In the two lower casings 1a, for example, the vertical connecting convex portions 2b, 2b on the both side portions are bent so as to approach each other, and the vertical connecting convex portions 2b, 2b in the central portion are in contact with each other. If bent in such a way that they are not bent, the bent vertical connection projections 2b, 2b, 2b, 2b are not exposed from the outer shape of the cardboard cabinet 1.
[0025]
Thereafter, the two second-stage casings 1a and 1a are placed on top of the lowermost casings 1a and 1a. As shown in FIG. 4B, the vertical connection is performed by inserting the upper vertical connection convex portions 2b into the lower vertical connection concave portions 2a. Then, if the two upper casings 1a are connected in the horizontal direction and the drawer 1A is inserted from the storage opening 1b, the cardboard cabinet 1 is completed.
[0026]
In the corrugated cardboard cabinet 1 completed as described above, since the reinforcing connecting member 2 is not exposed to the outside, even if it collides with the corrugated cardboard cabinet 1, the wrapping piece 1c around which the reinforcing connecting member 2 is wound is provided. Since it acts as an impact buffering material, it does not incur large injuries, and since the reinforcing connecting member 2 is not exposed to the outside, even if the reinforcing connecting member 2 is made of metal, it is not easily rusted and is a hard plastic. Dust is hard to adhere even if made. Furthermore, the cardboard cabinet 1 is simple and attractive because it is neatly aligned with no gaps because no gaps or protrusions are formed on its outer shape, and is unified with cardboard.
[0027]
In the above description, the connection procedure using the reinforcing connecting member 2 of claim 2 is shown. For example, the reinforcing connecting member 2 according to claim 1 (vertical connecting recesses 2a and 2a are formed at both ends) is adopted. In order to stack a plurality of stages in the vertical direction, the auxiliary tool according to claim 3 is vertically connected to the lower end of the reinforcing connecting member 2 located at the upper stage, and the vertical connecting recessed part at the upper end of the reinforcing connecting member 2 located in the lower stage. If an auxiliary tool is inserted into 2a and sequentially connected, the multistage number can be stably stacked.
[0028]
Further, even when the reinforcing connecting member 2 according to claim 2 is used, it is effective to use the auxiliary tool according to claim 3, that is, with respect to the vertical connecting concave portion 2a at the upper end of the reinforcing connecting member 2 located at the lower stage. If the auxiliary tool according to claim 3 attached to the vertical connection convex part 2b and the vertical connection convex part 2b at the lower end of the reinforcing connection member 2 positioned in the upper stage is inserted, this connection part is reinforced and more stable. Can be stacked.
[0029]
Furthermore, the cardboard cabinet 1 of the present invention is not limited to the above embodiment, and various modifications are possible. For example, the corrugated cardboard cabinet 1 in the above embodiment uses the casing 1a so that the vertical connection concave portion 2a is positioned at the upper end and the vertical connection convex portion 2b is positioned at the lower end. You may assemble by connecting.
