Description

本発明は、極めて短時間で設置することができ、使用時以外は扁平状に折り畳んで簡単に持ち運び及び収納を行うことができる段ボール製の折り畳み台に関する。 The present invention relates to a corrugated cardboard folding table that can be installed in an extremely short time and can be folded flat and easily carried and stored when not in use.

従来、災害等の発生により自宅で生活できなくなった被災者は、公民館や体育館等の避難所又は仮設住宅等で生活することがあるが、それぞれの被災者に割り当てられるスペースには限りがあると共に、そのような場所にベッドを搬入して設置することは困難である。そのため、被災者は、硬い床の上で、布団を敷いて寝たり、寝袋に入って寝たりしており、就寝中に苦痛を感じ易く、快眠が妨げられ、腰痛や睡眠不足等に悩まされるという問題があった。また、足腰が弱く、普段からベッドを使用して生活している高齢者等は、布団での寝起きが困難であるため、避難所又は仮設住宅等の使用に制限を受けるという問題もあった。そこで、段ボールで作製され、使用時以外はコンパクトに折り畳まれて収納され、持ち運びも容易な折り畳み式のベッド（例えば特許文献１）や、分解された状態で搬送され、必要な場所で組立てられて設置される様々な簡易（組立式）ベッド（例えば特許文献２〜５）が提案されている。 In the past, victims who could not live at home due to the occurrence of a disaster may live in evacuation shelters such as public halls and gymnasiums or temporary housing, but the space allocated to each victim is limited. , It is difficult to bring and install a bed in such a place. As a result, the victims sleep on a hard floor with a futon or sleep in a sleeping bag, which makes them more likely to feel pain while sleeping, hinders a good night's sleep, and suffers from back pain and lack of sleep. There was a problem. In addition, elderly people who have weak legs and usually live on beds have a problem that they are restricted from using evacuation shelters or temporary housing because it is difficult to get up with a futon. Therefore, a foldable bed (for example, Patent Document 1) that is made of corrugated cardboard, is compactly folded and stored when not in use, and is easy to carry, or is transported in a disassembled state and assembled at a required place. Various simple (assembly type) beds to be installed (for example, Patent Documents 2 to 5) have been proposed.

特開２０２０−１８８８７７号公報Japanese Unexamined Patent Publication No. 2020-188877 実用新案登録第３２２９６６０号公報Utility Model Registration No. 32296660 特開２０１２−２３５８１９号公報Japanese Unexamined Patent Publication No. 2012-235819 実用新案登録第３２０４２３６号公報Utility Model Registration No. 3204236 Gazette 特開２００９−５９０２号公報JP-A-2009-5902

特許文献１では、ベッドフレームを構成する左右一対の支持板と、両支持板の上縁部に載置された床板が、それぞれ蛇腹状に伸縮することにより折り畳まれ、ベッドフレームの前後に分割されたケース内に収納可能となっている。しかし、床板は、前後の端板、長手方向中央部で端板と平行に配置された中間板及びくの字に折れ曲がった左右の支持板のみで支持されている。つまり、端板、中間板及び支持板を構成する前後の屈曲板の隣接する端部同士が連結されているだけで、その他に互いを連結する連結材（補強材）を有していないため、床板の下側は、ほとんど中空で支えが少なく、使用者の体重による変形や破損が発生し易く、形状の安定性及び耐久性に欠けるという課題がある。
これに対し、特許文献２〜５では、床板（天板）を支持する脚部が、複数のシート（仕切り板）で格子状（井桁状）に形成されており、床板の変形を効果的に防止することができる。しかし、分解された状態で搬送されるため、設置場所において、複数のシートを、それぞれのシートに形成された切れ目（スリット）同士で噛合せ、格子状に配置して、床板を取り付けなければならず、組立に手間がかかるという課題がある。また、組立後は、簡単に分解することや折り畳むことが困難で、占有スペースを必要とし、設置場所が限定されるという課題もある。
本発明は、かかる事情に鑑みてなされたもので、折り畳み状態から、極めて短時間で設置することができ、簡素な構成でありながら形状安定性及び耐久性に優れると共に、使用時以外は、簡単に折り畳んで搬送及び収納を行うことができ、省スペース性、実用性及び機能性に優れ、主にベッドとして好適に用いることができる折り畳み台を提供することを目的とする。 In Patent Document 1, a pair of left and right support plates constituting the bed frame and floor plates placed on the upper edges of both support plates are folded by expanding and contracting in a bellows shape, and are divided into front and rear parts of the bed frame. It can be stored in the case. However, the floor plate is supported only by the front and rear end plates, the intermediate plate arranged parallel to the end plate in the central portion in the longitudinal direction, and the left and right support plates bent in a dogleg shape. That is, since the adjacent ends of the front and rear bending plates constituting the end plate, the intermediate plate and the support plate are only connected to each other, and there is no other connecting material (reinforcing material) to connect them to each other. The lower side of the floor board is almost hollow and has little support, and is easily deformed or damaged by the weight of the user, and has a problem of lacking shape stability and durability.
On the other hand, in Patent Documents 2 to 5, the legs supporting the floor plate (top plate) are formed in a grid pattern (well girder shape) by a plurality of sheets (partition plates), and the floor plate is effectively deformed. Can be prevented. However, since it is transported in a disassembled state, it is necessary to engage a plurality of sheets with the cuts (slits) formed in the respective sheets, arrange them in a grid pattern, and attach the floor plate at the installation location. However, there is a problem that it takes time and effort to assemble. In addition, after assembly, it is difficult to easily disassemble and fold it, an occupied space is required, and the installation location is limited.
The present invention has been made in view of such circumstances, and can be installed in an extremely short time from a folded state, has excellent shape stability and durability in spite of a simple configuration, and is easy except when in use. It is an object of the present invention to provide a folding table which can be folded and transported and stored, has excellent space saving, practicality and functionality, and can be preferably used mainly as a bed.

It should be noted that the top plate only needs to be able to perform folding and unfolding operations in conjunction with the legs, and the mounting method thereof is not limited to the present embodiment.

以上のように構成された折り畳み台１０は、非使用時に、図５、図６に示すように、天板１４が水平折り目３４で（正面視して逆Ｖ字状に）折り曲げられると、各第１の仕切り板１１が各垂直折り目２１で（平面視して逆Ｖ字状に）折り曲げられて各第２の仕切り板１２と重合（図６参照）し、仕切り壁１５（壁板１９）が脚部１３と連動して折り目２９で折り曲げられて、平面視して逆Ｖ字状に折り畳まれることにより、図７に示すように、全体が扁平状に折り畳まれる。
使用時は、図７の折り畳まれた状態から、図５、図６に示すように、壁板１７、１８の間隔を広げると、第１、第２の仕切り板１１、１２（脚部１３）、天板１４及び仕切り壁１５（壁板１９）が連動して展開し、図１〜図４に示した使用状態となる。ここで、図１、図２、図６、図７、図８（Ｃ）に示すように、天板１４の長手方向の中央部で、幅方向の他側（壁板１９の取付け位置と反対側）に、天板１４を脚部１３に固定する固定手段として、下方に折り曲げ可能な係止片３８が形成されている。そして、この係止片３８には、天板１４（第１の仕切り板１１）の長手方向の中央部に配置された第２の仕切り板１２の位置に対応して、第２の仕切り板１２の長手方向と平行に係止溝３９が形成されている。従って、使用時に、図１、図２に示すように、係止片３８を下方に折り曲げ、対応する第２の仕切り板１２の長手方向の他端側の切れ目２４に、係止溝３９を噛合せることにより、脚部１３の上面に対して天板１４を平坦状に保持し、天板１４の浮き上がりを防止することができる。 When the folding table 10 configured as described above is not in use, as shown in FIGS. 5 and 6, when the top plate 14 is folded at the horizontal crease 34 (in an inverted V shape when viewed from the front), each of the folding tables 10 is formed. The first partition plate 11 is bent at each vertical crease 21 (in an inverted V shape in a plan view) and overlaps with each second partition plate 12 (see FIG. 6), and the partition wall 15 (wall plate 19). Is bent at the crease 29 in conjunction with the leg portion 13 and folded in an inverted V shape in a plan view, so that the whole is folded flat as shown in FIG.
At the time of use, when the distance between the wall plates 17 and 18 is widened from the folded state of FIG. 7, as shown in FIGS. 5 and 6, the first and second partition plates 11 and 12 (legs 13) are used. , The top plate 14 and the partition wall 15 (wall plate 19) are interlocked and unfolded to be in the used state shown in FIGS. 1 to 4. Here, as shown in FIGS. 1, 2, 6, 7, and 8 (C), the central portion of the top plate 14 in the longitudinal direction is on the other side in the width direction (opposite the mounting position of the wall plate 19). On the side), a locking piece 38 that can be bent downward is formed as a fixing means for fixing the top plate 14 to the leg portion 13. Then, the locking piece 38 has a second partition plate 12 corresponding to the position of the second partition plate 12 arranged at the center of the top plate 14 (first partition plate 11) in the longitudinal direction. A locking groove 39 is formed parallel to the longitudinal direction of the above. Therefore, at the time of use, as shown in FIGS. 1 and 2, the locking piece 38 is bent downward, and the locking groove 39 is engaged with the cut 24 on the other end side in the longitudinal direction of the corresponding second partition plate 12. By doing so, the top plate 14 can be held flat with respect to the upper surface of the leg portion 13 and the top plate 14 can be prevented from rising.

なお、本実施の形態では、固定手段として、天板１４に１つだけ係止片３８を設けたが、その数は、限定されるものではない。また、複数の係止片を設ける場合は、各係止片を第２の仕切り板の位置に対応させて、適宜、配置することができ、その配置間隔は等間隔でも不等間隔でもよい。なお、固定手段は、折り畳み台の使用時に、天板を脚部に固定することができればよく、その形態は、限定されるものではない。
また、図８（Ｂ）に示すように、第２の仕切り板１２の長手方向の他側で切れ目２４の下方に丸孔状の指掛け部４１が形成されている。これにより、係止片３８の係止溝３９を切れ目２４に噛合せる際に、指掛け部４１に指を引っ掛ける（指掛け部４１を指で摘む）ようにして、第２の仕切り板１２を水平方向に引っ張ることができ、第２の仕切り板１２の上端側（切れ目２４の側方）が手で引っ張られることを防止して、第２の仕切り板１２が切れ目２４から破れる（引き裂かれる）ことを防ぐことができる。この指掛け部の形状及び大きさは、限定されるものではない。 In the present embodiment, only one locking piece 38 is provided on the top plate 14 as the fixing means, but the number thereof is not limited. Further, when a plurality of locking pieces are provided, each locking piece can be appropriately arranged in accordance with the position of the second partition plate, and the arrangement interval may be equal or unequal. The fixing means is not limited as long as the top plate can be fixed to the legs when the folding table is used.
Further, as shown in FIG. 8B, a round hole-shaped finger hook 41 is formed below the cut 24 on the other side of the second partition plate 12 in the longitudinal direction. As a result, when the locking groove 39 of the locking piece 38 is engaged with the cut 24, the second partition plate 12 is moved in the horizontal direction by hooking a finger on the finger hook portion 41 (picking the finger hook portion 41 with a finger). The second partition plate 12 can be pulled to prevent the upper end side (side of the cut 24) of the second partition plate 12 from being pulled by hand, and the second partition plate 12 can be torn (torn) from the cut 24. Can be prevented. The shape and size of the finger hook are not limited.

本実施の形態のように、全ての第２の仕切り板１２に指掛け部４１を形成することにより、第２の仕切り板の形状を全て共通化することができ、量産性及び組立時の作業性を向上させることができるが、指掛け部を形成した第２の仕切り板と、指掛け部を省略した第２の仕切り板を用意しておき、係止片の数及び配置に対応させて、２種類の第２の仕切り板を使い分けることもできる。なお、指掛け部は省略してもよい。
また、脚部１３を折り畳み状態から使用状態に展開する際に、指掛け部４１を利用して所望の第２の仕切り板１２を水平方向に引っ張ることができ、作業性に優れる。この場合、指掛け部は、第２の仕切り板の長手方向の一側及び／又は両側に形成することができる。
なお、第１の仕切り板及び第２の仕切り板の寸法（長さと高さ）、並びに、平面視した折り畳み台の縦横の長さ及び縦横比を適宜、選択（変更）することにより、大人用のベッド以外にも、例えば子供用や乳幼児用のベッド、長椅子、座椅子、ベンチ等として使用することが可能である。 By forming the finger hooks 41 on all the second partition plates 12 as in the present embodiment, all the shapes of the second partition plates can be made common, and mass productivity and workability at the time of assembly can be made. However, a second partition plate on which the finger hook portion is formed and a second partition plate in which the finger hook portion is omitted are prepared, and two types are prepared according to the number and arrangement of the locking pieces. It is also possible to use the second partition plate of. The finger hook may be omitted.
Further, when the leg portion 13 is unfolded from the folded state to the used state, the desired second partition plate 12 can be pulled in the horizontal direction by using the finger hook portion 41, which is excellent in workability. In this case, the finger hooks can be formed on one side and / or both sides in the longitudinal direction of the second partition plate.

In addition to the bed, it can be used as a bed for children and infants, a chaise longue, a sitting chair, a bench, and the like.

本実施の形態では、折り畳み台を縦方向（折り畳み台の長手方向）に押し潰す構造となっているが、第１の仕切り板の長さと第２の仕切り板の長さを逆転させて、折り畳み台を横方向（折り畳み台の幅方向）に押し潰す構造とすることもできる。
なお、本実施の形態では、図１、図３、図６、図７、図８（Ｃ）に示すように、天板１４の幅方向の一側に、水平折り目３４を挟んで対象に２つの切り欠き状の手掛け部４２を形成し、壁板１７、１８の幅方向の他側に、側面視して重なるように切り欠き状の手掛け部４３を１つずつ形成した。これにより、扁平状に折り畳んだ折り畳み台１０を、手掛け部４２、４３を利用して容易に持ち運ぶことができるが、手掛け部の形状、数及び配置は、本実施の形態に限られるものではない。 In the present embodiment, the folding table is crushed in the vertical direction (longitudinal direction of the folding table), but the length of the first partition plate and the length of the second partition plate are reversed to fold the folding table. The structure may be such that the table is crushed in the horizontal direction (the width direction of the folding table).
In this embodiment, as shown in FIGS. 1, 3, 6, 7, and 8 (C), a horizontal crease 34 is sandwiched on one side of the top plate 14 in the width direction. One notch-shaped handle 42 was formed, and one notch-shaped handle 43 was formed on the other side of the wall plates 17 and 18 in the width direction so as to overlap each other in a side view. Thereby, the folding table 10 folded flat can be easily carried by using the handle portions 42 and 43, but the shape, number and arrangement of the handle portions are not limited to the present embodiment. ..

次に、図１０〜図１６を参照して、本発明の第２の実施の形態に係る折り畳み台４５について説明する。なお、第１の実施の形態と同様の構成については、同一の符号を付して説明を省略する。
