【発明が属する技術分野】
本発明は、一般家庭や事務所などさまざまなところで、本及び書類の収納に使われてきた本箱に関するものであり、これまで本箱と言えば木製やプラスチック製またはブックエンドのような金属製のものなどが作られてきた。技術としては木工技術やプラスチック成型技術または金属加工技術の分野に属して、本を挟み込む工夫や装飾などの工夫はされてきたが、本箱と言う一つの完成した固定した形で扱われて来た。従って、完成した本箱を取り扱う場合は筐体の大きさが気になるところであった。
【０００２】
【従来の技術】
従来、本箱には色々の工夫が施されてきた。木製の本箱から始まり可変式に収納スペースが伸びて本が挟めるものやブックエンドのように両側から挟むもの、又は絵柄をあしらったものや彫刻を施したものなど種々な本箱が作られてきた。だが、薄板を使用する工夫はブックエンドにのみあらわれ、本箱の持つ厚板感に変わりはなかった。その為、本箱の製品の輸送や保管には多くのスペースが必要となり、コストが高いという欠点があった。
【０００３】
【発明が解決しようとする課題】
本箱は、製作し販売する場合、一つの完成した固定した形としてそのまま流通ルートに乗ることが多かった。その為、筐体の大きさが取り扱い難く、流通コストも上がり、保管スペースも大きくなった。ブックエンドのように重ねて扱う場合でも、立体としての形になってしまい取り扱い難さは残った。また、筐体が大きいものはネジ止めによる組立て家具などの形で存在するが、筐体が小さいものはそのまま搬送されていた。その為、輸送コストが高くなったり、保管場所に事欠くと言った問題点があった。
【０００４】
【課題を解決するための手段】
本発明は、本箱をより安いコストで市場に提供するため、本箱の素材にプラスチックや金属または紙材などの薄板を使用し、上下板と両横板から成る薄板４枚を、結合部が折れ曲がる状態で結合させ、背板があたる背面側に背板が差し込まれるような溝などの受けを設け、上下板と両横板を四角に立上げて背面側から上部両端が切除された背板を曲げて両横板の溝などの受けに差し込み、次に背板を押下げて下板の溝などの受けに差し込み、最後に背板を上板の下に押し込む。または、上板と両横板の接合部に背面側から２ｃｍ程度の切り込みを入れて上板をめくり上げ、背板を両横板の受けに差し込み、押下げて下板の溝などの受けに差し込みんだ後、上板につけられた垂れのホックや粘着テープなどで上板と背板を固定するようにした。または、組立ての簡略化を図り予め背板を上板か下板かどちらかの横板に折りたためる状態で結合しておき、組立て時に背板を背面側の背板の受けに押し当て仕切り板を仕切り板はめ込み溝や受けに挿入し筐体全体を固定するようにした。
【０００５】
また、本箱に収納される本や書類の高さの制限を排除する方法も考慮して、上記薄板４枚からなる上下板と両横板の内、上板のみ奥行きを１ｃｍ前後に小さくし、かつ、背板と仕切り板を折りたためる状態で一体化し、立ち上げた上下板と両横板の四角い枠の背面側から背板と仕切り板を仕切り板が下板の仕切り板支え用の溝などの受けに挿入されるようにしながら挿入した後、背板を両横板と下板につけた垂れのホックや粘着テープなどで固定するようにした。また、仕切り板の左右振れ防止のための補強として仕切り板の下部に垂れを付けホックで下板と固定するか、仕切り板の下部を延長して折り曲げ粘着テープなどで下板に固定する方法も取った。
【０００６】
【発明の実施の形態】
本発明は、折りたたみの出来る本箱の発明であり、図面に基づいて説明すれば、プラスチックや金属または紙材などの薄板を使用し、上下板１，２と両横板３，４から成る薄板４枚を上板１と下板２、横板３，４同士がそれぞれ向かい合い四角い枠を形成するように上板１と左右横板３，４、下板２と左右横板３，４を折れ曲がる機能を持ちながら結合するように連結させる。製作方法としては、プラスチックの場合は金型か切削加工により連結部を板厚よりも薄くし折れやすくする。紙材の場合は、上下板１，２と両横板３，４から成る薄板４枚を連結した状態で切り取り、折れ線を入れ、糊代に接着材をつけて貼り合わせる。金属や板の場合は、上下板１，２と両横板３，４から成る薄板４枚を蝶番のような機構により結合する。また、折りたたみの状態の完全な平らさを求めない方法として上記連結体に背板も一緒に結合してしまう方法もある。
【０００７】
また、上下板１，２と両横板３，４から成る薄板４枚の背面側には、背板５を差し込むための溝や受けを設け、かつ、上下板１，２と背板５には一定の間隔に仕切り板６の板差し込み溝を設ける。また、上下板に仕切り板６差込用溝を設けずに、仕切り板６をあらかじめ上下板に折りたためる状態で接着して、組立て時背板のみ差し込めば組立て完了にすることも出来る。この本箱は、複数の異なるサイズの本箱同士を連結させても、折りたたみ機能に変わりはないため、サイズの大きい本や書類が収納できるように、異なるサイズの本箱同士を連結させることも出来る。その際、連結する横板２枚を横板１枚で兼用することも可能である。この本箱は、搬送時は折りたたんで平たい状態にして取り扱える。また、使用時は簡単に組み立てられる。使わなくなった時は、再び仕切り板６と背板５を引き抜いて平らに折りたためば狭いスペースにも保管できる。
【０００８】
【実施例】
以下に本発明の一実施例について説明する。本箱の材料には厚さ２ｍｍの厚紙を使用した。上下板と両横板から成る厚紙４枚と糊代から成る厚紙を連結した状態で切り取り、背板１枚と仕切り板３枚も切り取った。背板は上部の両端を上から２ｃｍ程度、端から５ｍｍ程度切除した。次に上下板と両横板から成る厚紙４枚と糊代から成る厚紙の上下板と両横板の背面側の端から５ｍｍのところと上下板の中央と左右等間隔のところに幅２ｍｍ深さ１ｍｍの溝を掘り、各板のそれぞれの境に折り目を入れた。また、背板の中央と左右の上下板の溝間隔と同間隔のところにも幅２ｍｍ深さ１ｍｍの溝を掘った。次に、糊代に接着剤を付けて溝のある側を内側にして横板と下板を接合固定した。その後、上下板と両横板から成る厚紙４枚を平らに折りたたんだ状態から立上げ、背板を曲げて両横板の溝にはめ込み、押下げて下板の溝にはめ込んだ後、背板を上板の下に押し込み、上板の溝に背板をはめ込んだ。次に仕切り板３枚をそれぞれの上下板の溝にはめ込んで背板の溝にも嵌るように押し込んだ。その結果、１個の本箱が完成した。本を入れても倒れないで十分本箱としての機能を発揮することを確認した。また、本箱の上に物を置いても若干の歪みは生じるが２０ｋｇ以上耐えられることを確認した。
【０００９】
本箱の大きさは、高さ３２ｃｍ、幅３６ｃｍ、奥行き２５ｃｍにした。本箱の上に物を置いた場合、５ｋｇまでは全く歪みがなく、１０ｋｇまででも仕切り板に歪みは生じたが歪みの程度は小さいものであり、２０ｋｇぐらいになって漸く歪みが大きくなったが、本箱の形状は保っていた。実験後は、本箱の仕切り板３枚を溝から抜き、背板を溝から押し外し、本箱を平らに折りたたむことができた。
【００１０】
【発明の効果】
以上説明したように本発明の本箱は、平たい状態から無理なくスムーズに組み立てられ、使用しない時は再度平らに折りたたんでしまって置くことも出来る。従って、この本箱を製品化し、輸送する場合でも、輸送スペースが小さくて済むため、輸送コストは削減でき、かつ、薄板を利用することで材料面でのコストダウンと設置スペースの削減が図れる。また、保管して置く場合にも保管スペースが小さくて済むため、必要に応じて、組み立てたり畳んだりして手軽に本箱を利用することが出来る。また、上板の奥行きが大きいものは上に物を上げられると言った利点が生じ、逆に上板の奥行きが極端に小さいものは収納できる本や書類のサイズの制限がなくなる。また、異なるサイズの本箱同士の連結が可能なため、図８や図９のようなよりデザイン性のある本箱の実現も可能である。

[Technical field to which the invention belongs]
The present invention relates to a bookcase that has been used for storing books and documents in various places such as general homes and offices. Until now, a bookcase is made of metal such as wooden, plastic, or bookend. Things have been made. The technology belongs to the fields of woodworking technology, plastic molding technology, or metal processing technology, and has been devised to sandwich books and decorations, but it has been handled in one complete fixed form called a bookcase. It was. Therefore, when dealing with the completed bookcase, the size of the housing was a concern.
[0002]
[Prior art]
Conventionally, various ideas have been applied to bookcases. Various bookcases have been made, starting with wooden bookcases, with variable storage space that can be sandwiched between books, sandwiched from both sides like a bookend, or decorated with a pattern or engraved It was. However, the idea of using a thin plate appeared only at the book end, and the thick plate feeling of the bookcase was unchanged. Therefore, a lot of space is required for transportation and storage of the product in the bookcase, and there is a disadvantage that the cost is high.
[0003]
[Problems to be solved by the invention]
When bookcases were produced and sold, they were often put on the distribution route as a complete fixed form. For this reason, the size of the housing is difficult to handle, the distribution cost increases, and the storage space also increases. Even when it was handled in layers like a bookend, it became a solid shape and it was difficult to handle. In addition, a large casing exists in the form of assembly furniture by screwing, but a small casing is transported as it is. For this reason, there were problems such as high transportation costs and lack of storage space.
[0004]
[Means for Solving the Problems]
The present invention uses a thin plate made of plastic, metal, paper, or the like as the material of the book box in order to provide the book box to the market at a lower cost. The back of the back is cut off from the back side by providing a receiver such as a groove that allows the back plate to be inserted into the back side where the back plate hits. Bend the board and insert it into the grooves on both side plates, then push down the back plate and insert it into the groove on the lower plate, and finally push the back plate under the upper plate. Alternatively, make a cut of about 2cm from the back side at the joint between the top plate and both side plates, turn up the top plate, insert the back plate into the receptacles of both side plates, and press down to receive the grooves on the bottom plate. After inserting, the upper plate and the back plate were fixed with a hanging hook or adhesive tape attached to the upper plate. Or, to simplify the assembly, the back plate is joined in advance in a state where it is folded into either the upper plate or the lower plate, and the back plate is pressed against the back plate receiving plate at the time of assembly. Was inserted into the partition plate fitting groove or receiver to fix the entire housing.
[0005]
In addition, considering the method of eliminating the restriction on the height of the books and documents stored in the bookcase, the depth of only the upper plate of the upper and lower plates and the horizontal plates made of the four thin plates is reduced to about 1 cm, In addition, the back plate and the partition plate are integrated in a folded state, and the back plate and the partition plate are connected from the back side of the square frame of the up and down plates and the horizontal plates, and the partition plate is a groove for supporting the partition plate of the lower plate, etc. After being inserted while being inserted into the receiver, the back plate was fixed with hanging hooks or adhesive tape attached to both the lateral plate and the lower plate. In addition, as a reinforcement to prevent left and right runout of the partition plate, there is also a method of hanging the lower part of the partition plate and fixing it to the lower plate with a hook, or extending the lower part of the partition plate and fixing it to the lower plate with bending adhesive tape etc. I took it.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is an invention of a bookcase that can be folded. If explained based on the drawings, a thin plate made of plastic, metal, paper, or the like, and made up of upper and lower plates 1, 2 and both lateral plates 3, 4 is used. The upper plate 1 and the left and right horizontal plates 3, 4 and the lower plate 2 and the left and right horizontal plates 3, 4 are bent so that the four plates are the upper plate 1 and the lower plate 2, and the horizontal plates 3 and 4 face each other to form a square frame. Connect to have a function. As a manufacturing method, in the case of plastic, the connecting portion is made thinner than the plate thickness by a mold or cutting so that it can be easily broken. In the case of a paper material, it cuts out in the state which connected the four thin plates which consist of the upper-and-lower plates 1 and 2 and both the horizontal plates 3 and 4, puts a crease line, attaches an adhesive to an adhesive margin, and bonds together. In the case of a metal or a plate, four thin plates composed of upper and lower plates 1 and 2 and both lateral plates 3 and 4 are connected by a mechanism such as a hinge. In addition, as a method that does not require the complete flatness of the folded state, there is a method in which the back plate is also coupled to the connecting body.
[0007]
Further, grooves and receptacles for inserting the back plate 5 are provided on the back side of the four thin plates made up of the upper and lower plates 1 and 2 and the lateral plates 3 and 4, and the upper and lower plates 1, 2 and the back plate 5 Provides plate insertion grooves for the partition plate 6 at regular intervals. Further, without providing the partition plate 6 insertion groove on the upper and lower plates, it is possible to complete the assembly by bonding the partition plate 6 in a state of being folded in advance on the upper and lower plates and inserting only the back plate at the time of assembly. This bookcase can be used to connect bookshelves of different sizes so that large-sized books and documents can be stored because the folding function does not change even if a plurality of bookcases of different sizes are connected. . In that case, it is also possible to combine two horizontal plates to be connected with one horizontal plate. This bookcase can be folded and folded flat during handling. Also, it can be easily assembled when in use. When it is no longer used, it can be stored in a narrow space by pulling out the partition plate 6 and the back plate 5 and folding them back flat.
[0008]
【Example】
An embodiment of the present invention will be described below. A cardboard with a thickness of 2 mm was used as the material for the bookcase. 4 sheets of cardboard composed of upper and lower plates and both lateral plates and a cardboard composed of glue allowance were cut out, and one back plate and three partition plates were cut out. The back plate was excised from the top at both ends by about 2 cm and from the end by about 5 mm. Next, 4 thick paper sheets consisting of upper and lower plates and both horizontal plates, thick paper upper and lower plates made of glue margin, 5mm from the back edge of both horizontal plates, and the center of the upper and lower plates at a distance of 2mm wide A 1 mm long groove was dug, and a crease was made at each boundary of each plate. Further, a groove having a width of 2 mm and a depth of 1 mm was dug at the same interval as the groove interval between the center of the back plate and the left and right upper and lower plates. Next, an adhesive was attached to the glue margin, and the lateral plate and the lower plate were joined and fixed with the grooved side facing inward. Then, start up from the state that four thick paper sheets consisting of upper and lower plates and both horizontal plates are folded flat, bend the back plate and fit it into the grooves on both horizontal plates, push down and fit it into the groove on the lower plate, then back plate Was pushed under the upper plate, and the back plate was inserted into the groove of the upper plate. Next, the three partition plates were inserted into the grooves of the upper and lower plates and pushed so as to fit into the grooves of the back plate. As a result, one bookcase was completed. It was confirmed that the bookcase functioned well without falling down even if a book was put in. In addition, it was confirmed that even if an object was placed on the bookcase, it could withstand 20 kg or more although some distortion occurred.
[0009]
The size of the bookcase was 32 cm high, 36 cm wide, and 25 cm deep. When an object was placed on the bookcase, there was no distortion up to 5 kg, and the partition plate was distorted even up to 10 kg, but the degree of distortion was small, and the distortion gradually increased to about 20 kg. However, the shape of the bookcase was maintained. After the experiment, three bookcase partition plates were removed from the groove, the back plate was pushed out of the groove, and the bookcase could be folded flat.
[0010]
【The invention's effect】
As described above, the bookcase of the present invention can be assembled smoothly and smoothly from a flat state, and can be folded and laid flat again when not in use. Accordingly, even when this bookcase is commercialized and transported, the transport space can be reduced, so that the transport cost can be reduced, and the use of thin plates can reduce the material cost and the installation space. In addition, since the storage space is small even when stored, the bookcase can be easily used by assembling or folding as required. In addition, there is an advantage that an object with a large depth of the upper plate can lift an object, and conversely, an object with an extremely small depth of the upper plate has no limitation on the size of a book or document that can be stored. Further, since bookcases of different sizes can be connected to each other, it is possible to realize a bookcase with more design as shown in FIGS.
