Description

本発明は、ボックス体の組立構造及びそれを用いた引出しに係わり、更に詳しくはフラットパック化が可能な複数の部品から構成するボックス体の組立構造及びそれを用いた引出しに関するものである。 The present invention relates to an assembling structure of a box body and a drawer using the same, and more particularly to an assembling structure of a box body composed of a plurality of parts that can be formed into a flat pack and a drawer using the same.

従来から、引出しやキャビネット筐体をフラットパック化が可能な複数の部品から構成し、ノックダウン方式により現地で組み立てることが可能なものは各種提供されている。商品のフラットパック化は、商品在庫管理や搬送コストを低減する上で重要な技術である。ここで、引出しは、底板の後縁に後板を立起状態で連結するとともに、底板の両側縁に側板を立起状態に連結し、後板と側板の接合部を連結した状態で、底板と両側板の前縁に前板を取付けた上方開放のボックス体構造が一般的である。 Conventionally, various types of drawers and cabinet housings that are composed of a plurality of parts that can be made into a flat pack and can be assembled locally by a knockdown method have been provided. Flat packaging of products is an important technology for reducing product inventory management and transportation costs. Here, the drawer connects the rear plate to the rear edge of the bottom plate in an upright state, connects the side plate to the both side edges of the bottom plate in an upright state, and connects the joined portion of the rear plate and the side plate to the bottom plate. In general, the box structure is an open top with front plates attached to the front edges of both side plates.

特許文献１には、引出しにおいて、平板材料からなり、底板部分から四方に折曲部を介して後板部分、両側板部分及び前板部分を一体的に形成し、折曲部で直角に折り曲げて後板、両側板及び前板を立ち上げ形成し、各板の接合部となるコーナー部に平面視Ｌ字状のはめ込み固定部品を嵌合して連結し、前板の前面に化粧板を取付ける構造が開示されている。また、特許文献２には、引出しにおいて、底板部分から折曲部を介して後板部分あるいは後板部分と前板部分を一体的に形成し、折曲部で直角に折り曲げて後板あるいは後板と前板を立ち上げ形成し、それに側板を取付けるという構造が開示されている。特許文献１には、平板材料の材質には言及していないが、折曲部にＶ字溝を形成して９０°に折り曲げ可能とし、後板と両側板、前板と両側板の接合面を突き合わせ、はめ込み固定部品で連結した構造であるので、強度的に十分とは言えない。一方、特許文献２の底板部分と後板部分を形成する平板材料は合成樹脂製であり、折曲部で折り曲げて底板と後板を形成した後、樹脂成形品や鋼板材を折り曲げ加工した側板を連結するというもので、強度と耐久性において問題がある。尚、スチール製の平板材料に折曲部としてミシン目状の多数のスリットを設けたものもあるが、折曲時にスリットが破断する恐れがあるとともに、折曲部の外側にスリットによる凹凸や切断縁の毛羽立ちが生じるので外観的にも安全性にも問題がある。 Patent Document 1 discloses that a drawer is made of a flat plate material, and a rear plate portion, both side plate portions, and a front plate portion are integrally formed through a bent portion from the bottom plate portion in four directions and bent at a right angle at the bent portion. The back plate, both side plates, and the front plate are raised and formed, and a fitting part with an L-shaped fitting fixed part in a plan view is fitted and connected to the corner portion that becomes a joint portion of each plate, and a decorative plate is attached to the front surface of the front plate. A mounting structure is disclosed. Further, in Patent Document 2, in the drawer, the rear plate portion or the rear plate portion and the front plate portion are integrally formed from the bottom plate portion via the bent portion, and the rear plate or the rear plate is bent at a right angle at the bent portion. A structure in which a plate and a front plate are raised and a side plate is attached thereto is disclosed. Patent Document 1 does not mention the material of the flat plate material, but it can be bent at 90 ° by forming a V-shaped groove in the bent portion, and the joining surface of the rear plate and both side plates, and the front plate and both side plates. Is not sufficient in terms of strength. On the other hand, the flat plate material forming the bottom plate portion and the back plate portion of Patent Document 2 is made of synthetic resin, and after bending the bent portion to form the bottom plate and the rear plate, the side plate is formed by bending a resin molded product or a steel plate material. There is a problem in strength and durability. In addition, some steel flat plate materials are provided with a number of perforated slits as bent parts, but there is a risk that the slits may break when bent, and irregularities or cuts by slits on the outside of the bent parts There is a problem in appearance and safety because fuzz of the edge occurs.

特許文献３、４には、引出しにおいて、板金により作製した底板、後板、両側板及び前板からなり、底板の後縁に後板の下端を係合するとともに、底板の両側縁に両側板の下端を係合し、後板の両側縁に突設した突片を側板の後端に設けた孔に挿入後、折り曲げて連結する構造が開示されている。ここで、底板と両側板あるいは後板との連結構造は、底板の縁部の全長に渡って下方へ断面略Ｌ字状の折曲部を形成し、側板あるいは後板の下端の全長に前記底板の折曲部を抱き込む形状の鉤型折曲部を形成し、側板あるいは後板を底板の外側に倒した状態で両折曲部を係合し、内側へ回転させて立起させた状態で両係合部が離れないようにする構造である。この場合、突片を孔に挿入した後に９０°折り曲げる作業が必要となり、現地での組み立てに特殊な工具や熟練作業が必要になる。また、底板の外側に側板や後板を展開する余裕の施工スペースが必要となる。 Patent Documents 3 and 4 include a bottom plate, a rear plate, both side plates, and a front plate made of sheet metal in the drawer, and engage the lower end of the rear plate with the rear edge of the bottom plate and both side plates with both side edges of the bottom plate. A structure is disclosed in which the lower end of the rear plate is engaged, and projecting pieces protruding from both side edges of the rear plate are inserted into holes provided at the rear end of the side plate, and then bent and connected. Here, the connecting structure of the bottom plate and both side plates or the rear plate forms a bent portion having a substantially L-shaped cross section downward over the entire length of the edge portion of the bottom plate, and is connected to the entire length of the lower end of the side plate or the rear plate. Formed a saddle-shaped bent part that embraces the bent part of the bottom plate, engaged both bent parts with the side plate or rear plate tilted to the outside of the bottom plate, and rotated it to the inside to stand up In this state, the two engaging portions are not separated. In this case, it is necessary to bend 90 ° after inserting the projecting piece into the hole, and a special tool or skilled work is required for assembling on site. In addition, it is necessary to have a sufficient construction space for developing the side plate and the rear plate outside the bottom plate.

（１）〜（４）何れか１に記載のボックス体の組立構造を用い、前記底板と両側板の前端に前板を連結して上方開放したボックス体となしたことを特徴とする引出し。 (5)
(1)-(4) Drawer characterized by using the assembly structure of a box body according to any one of (1) and connecting a front plate to front ends of the bottom plate and both side plates to form a box body opened upward.

以上にしてなる本発明のボックス体の組立構造及びそれを用いた引出しは、以下に示す効果を奏する。 The assembly structure of the box body of the present invention and the drawer using the same have the following effects.

（１）の構成によれば、前記底板の上に後板及び両側板を重ねた倒伏姿勢から該後板及び両側板を外側へ回転させて立起姿勢に変化させて組み立てるので、施工スペースが最小となり、また底板と後板及び両側板は回転係合構造による連結であり、前記両側板の後縁上端部に突設した固定片を前記後板の両側端縁に当接した突き合い姿勢とし、該側板の後端上部を後板の側端上部に止着手段で連結するだけであるので、ネジ等の止着手段の使用数を最小限に抑制することができ、作業者１人で簡単に短時間で組み立てることができ、また後板や側板を倒伏姿勢から立起姿勢に変化させる際に、他方に干渉することなく回転変位させることができ、傷付きを防止できる。また、組立後は強度と耐久性を備えたボックス体となる。 According to the configuration of (1), since the rear plate and the both side plates are assembled to the standing posture by rotating the rear plate and the both side plates outward from the lying posture in which the rear plate and the both side plates are stacked on the bottom plate, the construction space is increased. The bottom plate, the rear plate, and both side plates are connected by a rotational engagement structure, and the abutting posture in which the fixed pieces projecting from the upper end portion of the rear edge of the both side plates are in contact with the both side edges of the rear plate Since only the rear end upper part of the side plate is connected to the side end upper part of the rear plate by fastening means, the number of fastening means such as screws can be minimized, and one worker As a result, the rear plate and the side plate can be rotated and displaced without interfering with the other when the rear plate or the side plate is changed from the lying posture to the standing posture, thereby preventing damage. Further, after assembly, the box body has strength and durability.

（２）の構成によれば、両側板を倒伏姿勢で係合片をスリット孔に受け入れて立起姿勢にするだけで、両側板を底板の側縁に連結することができ、また側板の下縁に沿って形成した折曲板が該側板の剛性を高めるとともに、前記底板の側縁から下面に沿って折曲板で受けることにより底板の支持強度が高くなるばかりでなく、底板の切断縁を隠して安全性を高めることができる。 According to the configuration of (2), the both side plates can be connected to the side edges of the bottom plate only by accepting the engaging pieces in the slit holes in the lying posture and bringing the engaging pieces into the standing posture. The bent plate formed along the edge increases the rigidity of the side plate, and not only the support strength of the bottom plate is increased by receiving the bent plate along the lower surface from the side edge of the bottom plate, but also the cutting edge of the bottom plate Can be hidden to increase safety.

（３）の構成によれば、底板に後板を回転係合構造により係合して立起姿勢に保持した状態で、前記側板を前記底板の上に重ねた倒伏姿勢で前記係合片を前記スリット孔の挿入部に受け入れ、この際に両側板は干渉回避位置にあるので前記後板に干渉することなく立起姿勢に回転変位させることができ、その後、両側板を後方へスライド変位させれば、前記係合片が前記スリット孔の係合部に係合するとともに、前記両側板の固定片を前記後板の両側端縁に当接した突き合い姿勢することができる。 According to the configuration of (3), in a state where the rear plate is engaged with the bottom plate by the rotary engagement structure and held in the standing posture, the engagement piece is held in the lying posture in which the side plate is stacked on the bottom plate. At this time, the both side plates are in the interference avoidance position so that they can be rotationally displaced in a standing posture without interfering with the rear plate, and then the both side plates are slid rearward. Then, the engaging piece engages with the engaging portion of the slit hole, and the fixed pieces of the both side plates can be brought into abutting posture in contact with both side edges of the rear plate.

（４）の構成によれば、底板の両側に両側板を回転係合構造により係合して立起姿勢に保持すると、該側板の下縁に設けた折曲板が底板の下面に当接した状態では、自動的に両側板の上部が外側へ開いた干渉回避姿勢となるので、この状態で底板に後板を回転係合構造により係合して立起姿勢に変化させる際に、両側板に干渉することなく後板を回転変位させることができ、その後、両側板を９０°の角度に内側へ回転させれば、前記両側板の固定片を前記後板の両側端縁に当接した突き合い姿勢することができる。 According to the configuration of (4), when the both side plates are engaged with both sides of the bottom plate by the rotary engagement structure and held in the standing posture, the bent plate provided on the lower edge of the side plate contacts the lower surface of the bottom plate. In this state, the top of both side plates automatically opens to the outside and the interference avoidance posture is set. Therefore, when the rear plate is engaged with the bottom plate by the rotational engagement structure in this state, The rear plate can be rotated and displaced without interfering with the plate. After that, if both side plates are rotated inward by 90 °, the fixed pieces of the both side plates are brought into contact with both side edges of the rear plate. Can be a butt posture.

（５）の構成によれば、構成部品をフラットパック化ができるので、商品在庫管理や搬送コストを低減することができ、現地での組み立てに際して特殊な工具や熟練作業が不要であり、また施工スペースを最小化でき、組立後の構造が強度と耐久性を備えている引出しを提供できる。 According to the configuration of (5), the component parts can be made into a flat pack, so that it is possible to reduce merchandise inventory management and transportation costs, and no special tools or skilled work is required when assembling locally. Space can be minimized, and drawers can be provided where the assembled structure is strong and durable.

The fixing pieces 10 have through holes 13, and the mounting pieces 12 have pilot holes 14. The tapping screw is screwed into the pilot hole 14 from the through hole 13 as the fastening means 11. In addition, it is also possible to fit a resin fastener instead of a screw as the fastening means 11. A front plate 6 is attached to the front ends of the bottom plate 3 and the side plates 5 and 5 to form a drawer 2. Note that a rail 15 is attached to the outer surface of the side plate 5 at the lower edge, and an accessory fitting 16 such as a stopper constituting a locking mechanism is fixed above the rail 15 in advance.

先ず、前記底板３は、図３及び図４に示すように、長方形のスチール製基板の後縁の両側部に上方へ直角に上片１７，１７を形成するとともに、前縁の両側部に下方へ直角に下片１８，１８を折曲形成し、更に両側縁の前後部に少なくとも２つの上向き係合片１９，１９を形成したものである。 First, as shown in FIGS. 3 and 4, the bottom plate 3 is formed with upper pieces 17 and 17 at right angles on both sides of the rear edge of the rectangular steel substrate and at the lower side on both sides of the front edge. The lower pieces 18, 18 are bent at right angles to each other, and at least two upward engaging pieces 19, 19 are formed on the front and rear portions of both side edges.

前記後板４は、長方形のスチール製基板の上縁に外側へ向けて補強縁２０を折曲形成するとともに、該補強縁２０の端部に前記取付片１２が基板と直角の向きに形成され、更に下縁の両側部には内向き（前向き）となるように支持片２１，２１を直角に折曲形成するとともに、該支持片２１の折曲部には前記底板３の上片１７を受け入れる横長孔２２がそれぞれ形成され、そして両側縁の上下部には前向きとなるように受片２３，２３を直角に折曲形成している。 The rear plate 4 has a reinforcing edge 20 bent outwardly at the upper edge of a rectangular steel substrate, and the mounting piece 12 is formed at the end of the reinforcing edge 20 in a direction perpendicular to the substrate. Further, support pieces 21 and 21 are bent at right angles so as to be inward (forward) on both sides of the lower edge, and the upper piece 17 of the bottom plate 3 is formed on the bent portion of the support piece 21. Receiving horizontally long holes 22 are respectively formed, and receiving pieces 23 and 23 are bent at right angles so as to face forward on upper and lower sides of both side edges.

前記底板３と後板４との回転係合構造７は、前記底板３の上片１７と前記後板４の支持片２１及び該支持片２１に形成された横長孔２２とで構成される。前記底板３に後板４を連結するには、先ず、図４に示すように、底板３の後部の上に後板４を重ねるとともに、前記上片１７を横長孔２２に受け入れた倒伏姿勢とする（図３及び図５（ａ）参照）。図３の状態では、左右両側縁において、前記係合片１９と受片２３，２３が相手側の縁部を抱き込むような状態となっており、非常に安定するのでこの状態で梱包することが好ましい。それから、前記上片１７と横長孔２２を支点として前記後板４の前側部分を回転させて起こし、図５（ｂ）に示すように、前記後板４の支持片２１を底板３の下面に回り込むようにする。それから、図５（ｃ）に示すように、前記後板４を完全に起こして立起姿勢にすると、前記上片１７が後板４の外側面に当接し、前記支持片２１が底板３の下面に当接して立起状態が維持される。ここで、前記底板３の上に後板４を重ねて状態で該底板３を作業面に置くと、前記底板３の後部には支える部分が存在せず、前記後板４の支持片２１のみが作業面に当接するので、前記上片１７が横長孔２２から抜ける恐れがあり、そのため前記上片１７の後面にダボ２４を突設するとともに、前記横長孔２２の内部に前記支持片２１の延長方向に爪片２５を設け、図５（ａ）の重ね合わせた状態で、前記爪片２５でダボ２４を載支している。 The rotational engagement structure 7 between the bottom plate 3 and the rear plate 4 includes an upper piece 17 of the bottom plate 3, a support piece 21 of the rear plate 4, and a horizontally long hole 22 formed in the support piece 21. In order to connect the rear plate 4 to the bottom plate 3, first, as shown in FIG. 4, the rear plate 4 is overlaid on the rear portion of the bottom plate 3, and the lying posture is such that the upper piece 17 is received in the horizontally long hole 22. (See FIG. 3 and FIG. 5 (a)). In the state of FIG. 3, the engagement piece 19 and the receiving pieces 23 and 23 embrace the edge of the other party on both the left and right edges, and the packaging is performed in this state because it is very stable. Is preferred. Then, the front portion of the rear plate 4 is rotated by using the upper piece 17 and the horizontally long hole 22 as a fulcrum, and the support piece 21 of the rear plate 4 is placed on the lower surface of the bottom plate 3 as shown in FIG. Try to wrap around. Then, as shown in FIG. 5 (c), when the rear plate 4 is completely raised to the upright posture, the upper piece 17 comes into contact with the outer surface of the rear plate 4, and the support piece 21 is attached to the bottom plate 3. The upright state is maintained in contact with the lower surface. Here, when the bottom plate 3 is placed on the work surface in a state where the rear plate 4 is overlaid on the bottom plate 3, there is no supporting portion on the rear portion of the bottom plate 3, and only the support piece 21 of the rear plate 4 is present. , The upper piece 17 may come out of the horizontally long hole 22, so that a dowel 24 protrudes from the rear surface of the upper piece 17, and the support piece 21 is placed inside the horizontally long hole 22. A claw piece 25 is provided in the extending direction, and the dowel 24 is supported by the claw piece 25 in the state of being overlapped in FIG.

次に、前記側板５は左右対称形であり、図２、図７及び図８に示すように、長方形のスチール製基板の上縁に外側へ向けて補強縁２６を折曲形成するとともに、基板の両側縁上端部に前記固定片１０を延長形成し、下縁には前記底板３の側縁から下面に沿って係合する折曲板２７を形成するとともに、該折曲板２７の折曲部に前記底板３の係合片１９，１９を受け入れるスリット孔２８，２８を形成している。前記両側板５，５と底板３との回転係合構造８は、前記底板３の側縁の前後部に形成した係合片１９と、前記側板５の折曲板２７及び該折曲板２７の折曲部に形成したスリット孔２８とで構成されている。 Next, the side plate 5 is bilaterally symmetric, and as shown in FIGS. 2, 7 and 8, a reinforcing edge 26 is bent outward from the upper edge of the rectangular steel substrate, and the substrate The fixed pieces 10 are formed to extend at the upper ends of both side edges, and a bent plate 27 is formed at the lower edge to be engaged along the lower surface from the side edge of the bottom plate 3. Slit holes 28 and 28 for receiving the engagement pieces 19 and 19 of the bottom plate 3 are formed in the part. The rotary engagement structure 8 between the side plates 5, 5 and the bottom plate 3 includes an engagement piece 19 formed at the front and rear portions of the side edge of the bottom plate 3, the folding plate 27 of the side plate 5, and the folding plate 27. And a slit hole 28 formed in the bent portion.

そして、前記底板３と両側板５，５を連結するには、先ず、図７及び図８に示すように、前記底板３の両側部の上に前記側板５をそれぞれ重ねるとともに、前記底板３の係合片１９，１９を前記側板５のスリット孔２８，２８に受け入れて倒伏姿勢とする。それから、前記両側板５，５の上部を外側へ回転させて立起姿勢にすると、前記側板５の折曲板２７が底板３の下面へ回り込み、該下面に当接して支持するとともに、前記係合片１９，１９が前記側板５の外側面に当接する。 In order to connect the bottom plate 3 and the side plates 5 and 5, first, as shown in FIGS. 7 and 8, the side plates 5 are overlapped on both side portions of the bottom plate 3, respectively. The engaging pieces 19 and 19 are received in the slit holes 28 and 28 of the side plate 5 to be in a lying posture. Then, when the upper portions of the side plates 5 and 5 are rotated outward to be in an upright posture, the bent plate 27 of the side plate 5 goes around the lower surface of the bottom plate 3 and contacts and supports the lower surface. The combined pieces 19, 19 abut on the outer surface of the side plate 5.

前記干渉回避手段９は、前記スリット孔２８に設けられ、該スリット孔２８は、前記側板５が前記底板３に対して所定位置よりも前寄りの干渉回避位置で前記底板３の係合片１９，１９を受け入れる挿入部２８Ａと、該挿入部２８Ａから前方へ連続して延びた係合部２８Ｂとから構成されている。そして、前記側板５を前記底板３の上に重ねた倒伏姿勢で前記係合片１９，１９を前記スリット孔２８の挿入部２８Ａに受け入れ、該側板５を立起姿勢とした後、干渉回避手段９の解除機能として後方へスライドさせた際に前記係合片１９，１９が前記スリット孔２８の係合部２８Ｂに密に係合するとともに、前記両側板５の固定片１０を予め立起姿勢とした前記後板４の両側端縁に当接した突き合い姿勢となり、止着手段１１（ネジ）で前記取付片１２に止着するのである。 The interference avoiding means 9 is provided in the slit hole 28, and the slit hole 28 is an engagement piece 19 of the bottom plate 3 at an interference avoiding position where the side plate 5 is closer to the bottom plate 3 than a predetermined position. , 19 and an engaging portion 28B continuously extending forward from the inserting portion 28A. Then, the engagement pieces 19, 19 are received in the insertion portion 28A of the slit hole 28 in a lying posture in which the side plate 5 is overlaid on the bottom plate 3, and after the side plate 5 is set in the standing posture, interference avoiding means As the release function of 9, the engagement pieces 19, 19 are closely engaged with the engagement portion 28B of the slit hole 28 when being slid rearward, and the fixed pieces 10 of the side plates 5 are raised in advance. The abutting posture comes into contact with both side edges of the rear plate 4 and is fastened to the mounting piece 12 by fastening means 11 (screws).

前記干渉回避手段９によって、予め底板３の後縁に後板４を立起姿勢に連結した状態で、両側板５，５を底板３の上面両側部に倒伏姿勢で重ねた後、両側板５，５を外側へ回転させて立起させる際に、該側板５の後縁に突設した固定片１０が前記後板４に接触することがないのである。この状態で前記係合片１９は、スリット孔２８の挿入部２８Ａに位置し、該挿入部２８Ａは前記側板５を回転させて立起させる動作に支障がないように広幅に形成している。一方、前記スリット孔２８の係合部２８Ｂは、立起姿勢の前記側板５を後方へスライド移動させるだけであるので、幅狭として係合状態においてガタつかないようにしている。前記側板５を立起姿勢で後方へスライド移動させて、前記側板５の固定片１０を前記後板４の側縁の外側に位置させるとともに、前記後板４の受片２３，２３を前記側板５の外側面に位置させ、後板４と側板５の端縁同士を接合させる。この状態で、前記固定片１０は前記取付片１２の外側面に重なる。 After the rear plate 4 is connected to the rear edge of the bottom plate 3 in an upright posture by the interference avoiding means 9 in advance, the side plates 5 and 5 are overlapped on both sides of the upper surface of the bottom plate 3 in a lying posture. , 5 is rotated outward and raised to prevent the fixed piece 10 protruding from the rear edge of the side plate 5 from coming into contact with the rear plate 4. In this state, the engagement piece 19 is positioned at the insertion portion 28A of the slit hole 28, and the insertion portion 28A is formed wide so as not to hinder the operation of rotating and raising the side plate 5. On the other hand, the engaging portion 28B of the slit hole 28 only slides the side plate 5 in the standing posture backward, so that it is narrow so that it does not rattle in the engaged state. The side plate 5 is slid rearward in an upright position so that the fixed piece 10 of the side plate 5 is positioned outside the side edge of the rear plate 4, and the receiving pieces 23, 23 of the rear plate 4 are moved to the side plate. 5, the end edges of the rear plate 4 and the side plate 5 are joined to each other. In this state, the fixed piece 10 overlaps the outer surface of the mounting piece 12.

最後に、前記底板３と両側板５，５の前端に前記前板６を連結するのである。本発明においては、この前板６の連結構造は任意である。一例を図９及び図１１に基づいて説明する。前記前板６の背面側に前記両側板５，５の内面間隔に等しく、また該側板５の高さにほぼ等しい裏板部２９を突出形成している。前記前板６の裏板部２９の下端のコーナー部に前記底板３の下片１８，１８を受け入れる横長孔３０，３０を形成してあり、該前板６は前記裏板部２９を上にして伏せた状態で、前記底板３の下片１８，１８を横長孔３０，３０に挿入する。その状態から前板６の上部を起こして前記下片１８，１８を横長孔３０，３０に深く係合させるとともに、前記裏板部２９を両側板５，５間に係合させる。その状態で、側板５の前縁部上部に形成した取付孔３１に外側からタッピングネジ３２を挿入し、裏板部２９の側面に形成した下穴３３に螺合して固定する。この場合もタッピングネジ３２の代わりに樹脂ファスナーを用いることも可能である。以上の引出し２の組み立てには、僅か４ヶ所でネジ止めするだけであり、１人の作業者が簡単に短時間で施工できる。 Finally, the front plate 6 is connected to the front ends of the bottom plate 3 and the side plates 5 and 5. In the present invention, the connecting structure of the front plate 6 is arbitrary. An example will be described with reference to FIGS. A back plate portion 29 is formed on the back side of the front plate 6 so as to protrude, which is equal to the inner surface spacing of the side plates 5 and 5 and substantially equal to the height of the side plate 5. Horizontal long holes 30 and 30 for receiving the lower pieces 18 and 18 of the bottom plate 3 are formed at the lower corners of the back plate portion 29 of the front plate 6, and the front plate 6 faces the back plate portion 29 upward. The bottom pieces 18 and 18 of the bottom plate 3 are inserted into the laterally long holes 30 and 30 in a state where they are bent down. From this state, the upper portion of the front plate 6 is raised to engage the lower pieces 18 and 18 deeply with the horizontally elongated holes 30 and 30, and the back plate portion 29 is engaged between the side plates 5 and 5. In this state, a tapping screw 32 is inserted from the outside into the mounting hole 31 formed in the upper part of the front edge of the side plate 5 and is screwed into and fixed to a pilot hole 33 formed in the side surface of the back plate portion 29. In this case, a resin fastener can be used instead of the tapping screw 32. The assembly of the above drawer 2 is only screwed at four places, and one worker can easily perform the construction in a short time.

次に、本発明の第２実施形態を図１２〜図１６に基づいて説明する。基本的な構成は前述の第１実施形態と同様であるので、同一構成には同一符号を付して、その説明は省略する。第１実施形態と大きく異なるのは、前記干渉回避手段９の構成である。 Next, a second embodiment of the present invention will be described with reference to FIGS. Since the basic configuration is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and the description thereof is omitted. A significant difference from the first embodiment is the configuration of the interference avoiding means 9.

第２実施形態の干渉回避手段９は、前記折曲板２７に設けられ、該折曲板２７は側板５の面板に対して９０°より大きな角度に形成し、前記側板５を前記底板３の上に重ねた倒伏姿勢で前記係合片１９，１９を前記スリット孔２８，２８に受け入れ、該側板５を立起姿勢とした際に、前記折曲板２７が前記底板３の下面に当接した状態で両側面板５，５の上部が外側に開いた干渉回避姿勢となるものである（図１４参照）。その状態で前記後板４を両側板５，５間の底板３の後部に倒伏姿勢で重ねた状態から回転させて起こして立起姿勢とした後、前記干渉回避手段９の解除手段として前記両側板５，５を内側に回転変位させて両側板５，５の固定片１０を前記後板４の両側端縁に当接した突き合い姿勢とし、該固定片１０を前記後板４の取付片１２にネジ等の止着手段１１で止着するのである。 The interference avoiding means 9 of the second embodiment is provided on the bent plate 27, the bent plate 27 is formed at an angle larger than 90 ° with respect to the face plate of the side plate 5, and the side plate 5 is attached to the bottom plate 3. When the engagement pieces 19 and 19 are received in the slit holes 28 and 28 in the lying posture superimposed on the side plate 5 and the side plate 5 is set in the standing posture, the bent plate 27 contacts the lower surface of the bottom plate 3. In this state, the upper portions of the side plates 5 and 5 are in an interference avoidance posture where the upper portions are opened outward (see FIG. 14). In this state, the rear plate 4 is rotated from a state where it is piled on the rear portion of the bottom plate 3 between the side plates 5 and 5 in a lying posture, and is raised to a standing posture. The plates 5 and 5 are rotationally displaced inward so that the fixed pieces 10 of the side plates 5 and 5 are in contact with both side edges of the rear plate 4, and the fixed pieces 10 are attached to the rear plate 4. It is fixed to 12 with fixing means 11 such as a screw.

本実施形態では、前記底板３と後板４の回転係合構造７は、前述の第１実施形態と同じである。また、前記底板３と側板５の回転係合構造８も干渉回避手段９を除いて基本的には共通である。本実施形態では、前記底板３に前記両側板５，５を先に連結し、その後で底板３に後板４を連結した後、該後板４と側板５を止着手段１１で止着する手順で組み立てる。 In the present embodiment, the rotational engagement structure 7 between the bottom plate 3 and the rear plate 4 is the same as that in the first embodiment. The rotational engagement structure 8 of the bottom plate 3 and the side plate 5 is basically the same except for the interference avoiding means 9. In the present embodiment, the side plates 5 and 5 are connected to the bottom plate 3 first, and then the rear plate 4 is connected to the bottom plate 3, and then the rear plate 4 and the side plate 5 are fixed by the fixing means 11. Assemble in the procedure.

更に詳しくは、図１２に示すように、前記側板５の折曲板２７の折曲部に形成したスリット孔２８は、前記係合片１９が前後に移動することなく係合する長さに設定され、通常の側板５の設置位置に形成されている。前記側板５の面板と前記折曲板２７とのなす角度αは９２°に設定している。この角度αは、図１４の両側板５，５が立起姿勢で、その間で前記後板４を倒伏姿勢から立起姿勢に変化させる際に（図１５参照）、該後板４の両側端が前記側板５に接触しない最小限の角度に設定する。この角度αが大きすぎると、側板５を立起姿勢にした状態で、前記折曲板２７で底板３の下面を支持するのに支障が生じる。 More specifically, as shown in FIG. 12, the slit hole 28 formed in the bent portion of the bent plate 27 of the side plate 5 is set to a length that allows the engagement piece 19 to be engaged without moving back and forth. It is formed at the position where the normal side plate 5 is installed. An angle α formed by the face plate of the side plate 5 and the bent plate 27 is set to 92 °. This angle α is determined when the side plates 5 and 5 of FIG. 14 are in the standing posture, and the rear plate 4 is changed from the lying posture to the standing posture in the meantime (see FIG. 15). Is set to a minimum angle that does not contact the side plate 5. If the angle α is too large, there will be a problem in supporting the lower surface of the bottom plate 3 with the bent plate 27 in a state where the side plate 5 is in the standing posture.

本実施形態が前述の第１実施形態と異なる点は、前記後板４の受片２３，２３を無くし、その代わりに側板５の後縁下部に内向きになるように受片３４を直角に折曲形成し、前記後板４を図１５の倒伏姿勢から立起姿勢に回転させて起こした際に、該後板４の外側面を前記両側板５，５の受片３４，３４で当止するようにしている。そして、やや上部が開いた立起姿勢の両側板５，５間に、前記回転係合構造７にて前記後板４を立起姿勢に連結した状態で、図１６に示すように、両側板５，５を内側へ回転させて前記固定片１０を前記後板４の取付片１２に接合し、止着手段１１で止着する。 The present embodiment is different from the first embodiment described above in that the receiving pieces 23 and 23 of the rear plate 4 are eliminated, and instead the receiving pieces 34 are arranged at right angles so as to be inward at the lower rear edge of the side plate 5. When the rear plate 4 is bent and rotated from the lying posture to the upright posture in FIG. 15, the outer surface of the rear plate 4 is abutted by the receiving pieces 34, 34 of the side plates 5, 5. I try to stop. In the state where the rear plate 4 is connected to the standing posture by the rotary engagement structure 7 between the side plates 5 and 5 in the standing posture with the upper part slightly open, as shown in FIG. 5 and 5 are rotated inward to join the fixed piece 10 to the attachment piece 12 of the rear plate 4 and fastened by the fastening means 11.
