Description

本発明は、金属材で形成されたコンテナに係り、特に、連結部の強度を高めて、比較的薄い金属板材で製造しても全体の強度を確保できるコンテナに関する。 The present invention relates to a container made of a metal material, and more particularly to a container capable of increasing the strength of a connecting portion and ensuring the overall strength even when manufactured with a relatively thin metal plate material.

各種の荷物を収納して輸送や保管するためのコンテナは、使用する直前に組立てて、使用後は解体して廃棄しまたは資材を再利用するのが好ましい。 Containers for storing, transporting, and storing various types of luggage are preferably assembled immediately before use, disassembled and discarded after use, or the materials are reused.

特許文献１には、コンテナ用資材で組み立てられて、使用後に分解が可能なコンテナに関する発明が記載されている。 Patent Document 1 describes an invention relating to a container that is assembled from a container material and can be disassembled after use.

このコンテナは、プラスチック製の四角形のパレットの辺部の複数箇所に、連結部材が装着され、パレットの４つの側面を覆う側部構造体の下部が、連結部材によってパレットに固定されている。それぞれの側部構造体は上部フレームと下部フレーム、および２本の側部垂直フレームと中央垂直フレームとを有している。それぞれの側部垂直フレームと中央垂直フレームとの間に、２本の傾斜フレームが固定されている。 In this container, connecting members are attached to a plurality of sides of a plastic square pallet, and the lower portion of a side structure covering the four side surfaces of the pallet is fixed to the pallet by the connecting members. Each side structure has an upper frame and a lower frame, and two side vertical frames and a central vertical frame. Two inclined frames are fixed between each side vertical frame and the center vertical frame.

連結部材は、金属板で形成されており、上向き支持面と、側部構造体の外面側で、上向き支持面から折り返された上側保持板部と、内面側で上向き支持面から垂直に立ち上がる上向き板部とが一体に形成されている。側部構造体の下部フレームはＬ字形の金属板で形成されて、水平板部と垂直板部とを有している。下部フレームの水平板部を、連結部材の上向き支持面と上側保持板部との間に挟み込んで、垂直板部を連結部材の上向き板部の内面に突き当てることで、側部構造体がパレットから垂直に立ち上がるように組み込まれる。 The connecting member is formed of a metal plate, and has an upward support surface, an upper holding plate portion folded back from the upward support surface on the outer surface side of the side structure, and an upward support plate portion that rises vertically from the upward support surface on the inner surface side. The plate portion is integrally formed. The lower frame of the side structure is formed of an L-shaped metal plate and has a horizontal plate portion and a vertical plate portion. The horizontal plate portion of the lower frame is sandwiched between the upward support surface of the connecting member and the upper holding plate portion, and the vertical plate portion is abutted against the inner surface of the upward plate portion of the connecting member, whereby the side structure is palletized. It is built in so that it stands up vertically from.

コンテナの上部の４か所の角部では、隣り合う側部構造体の側部垂直フレームどうしが組み合わされ、隣り合う側部構造体の端部どうしが、上部連結金具で連結される。 At the four corners of the upper part of the container, the side vertical frames of the adjacent side structures are combined, and the ends of the adjacent side structures are connected by the upper connecting metal fittings.

特開２０１３−１５９３５３号公報Japanese Unexamined Patent Publication No. 2013-159353

特許文献１に記載されているコンテナは、パレットがプラスチック材料で厚く形成されて底部の剛性が高くなっている。さらに、側部構造体を構成する複数のフレームや連結部材などを厚い金属板で形成すればコンテナ全体の剛性を高めることができ、パレットと側部構造体との連結部や、側部構造体どうしの連結部の連結強度を比較的高くすることが可能である。 In the container described in Patent Document 1, the pallet is thickly formed of a plastic material and the rigidity of the bottom is high. Further, if a plurality of frames and connecting members constituting the side structure are formed of a thick metal plate, the rigidity of the entire container can be increased, and the connecting portion between the pallet and the side structure and the side structure can be increased. It is possible to make the connection strength of the connecting portions of each other relatively high.

しかし、軽量化とコスト削減のために、パレットに代わる底部構造体や側部構造体および連結部材を、比較的薄い金属板で形成しようとすると、コンテナの全体の剛性が低くなるのを避けることができない。 However, in order to reduce the weight and cost, if the bottom structure, side structure and connecting member to replace the pallet are formed of a relatively thin metal plate, the overall rigidity of the container should be avoided. I can't.

剛性の低いコンテナにおいて、特許文献１に記載のように、隣り合う側部構造体の側部垂直フレームを上部連結金具で上から押えただけの構造では、隣り合う側部構造体の側部垂直フレームどうしの上下方向の相対的な位置ずれに対して十分な連結強度を確保することができない。例えば、コンテナをフォークリフトで持ち上げて移動させるような作業において、コンテナの剛性が低いと、コンテナ全体に歪みが発生して、隣り合う側部構造体の側部垂直フレームどうしが、相対的に上下に位置ずれしやすくなる。このとき、上部連結金具が外れるおそれがある。 In a container with low rigidity, as described in Patent Document 1, in a structure in which the side vertical frames of adjacent side structures are simply pressed from above by the upper connecting metal fittings, the side verticals of the adjacent side structures are vertical. Sufficient connection strength cannot be ensured against the relative positional deviation of the frames in the vertical direction. For example, in work such as lifting and moving a container with a forklift, if the rigidity of the container is low, distortion will occur in the entire container, and the side vertical frames of adjacent side structures will move relatively up and down. It becomes easy to shift the position. At this time, the upper connecting metal fitting may come off.

また、側部構造体の下部フレームを薄い金属板で形成すると、下部フレームと連結部材との連結部での強度も低下しやすくなる。この場合も、コンテナの中央部がフォークリフトなどで持ち上げられて、コンテナ全体に歪みが発生すると、下部フレームが変形しやすくなって、下部フレームの水平板部が、連結部材における上向き支持面と上側保持板部との間から外れるなどの課題が生じやすくなる。 Further, when the lower frame of the side structure is formed of a thin metal plate, the strength of the connecting portion between the lower frame and the connecting member tends to decrease. Also in this case, if the central part of the container is lifted by a forklift or the like and the entire container is distorted, the lower frame is easily deformed, and the horizontal plate part of the lower frame is held upward with the upward support surface of the connecting member. Problems such as disconnection from the plate are likely to occur.

本発明は上記従来の課題を解決するものであり、側部構造体どうしの連結部や、底部構造体と側部構造体との連結部での連結強度を高めることができ、比較的剛性の低い材料を使用しても、連結強度を確保することができるコンテナを提供することを目的としている。 The present invention solves the above-mentioned conventional problems, and can increase the connecting strength at the connecting portion between the side structures and the connecting portion between the bottom structure and the side structure, and is relatively rigid. The purpose is to provide a container that can secure the connection strength even if a low material is used.

本発明のコンテナでは、前記下かまちを、前記底部連結金具よりも薄い金属板で形成することが可能である。 In the container of the present invention, the lower stile can be formed of a metal plate thinner than the bottom connecting metal fitting.

本発明のコンテナは、側部構造体の連結部において、一方の側部構造体の支柱の端部と上かまちとの間の隙間に、他方の側部構造体の上かまちを挟むようにしている。その結果、コンテナの上側角部での側部構造体どうしの連結強度を高くでき、例えばコンテナを薄い金属板で構成して、コンテナ全体が歪みやすくなっていても、隣り合う側部構造体が上下方向へ相対的に位置ずれするのを規制できる。 In the container of the present invention, at the connecting portion of the side structure, the upper stile of the other side structure is sandwiched in the gap between the end of the column of one side structure and the upper stile. As a result, the connection strength between the side structures at the upper corners of the container can be increased. For example, even if the container is made of a thin metal plate and the entire container is easily distorted, the adjacent side structures can be formed. It is possible to regulate the relative displacement in the vertical direction.

また、底部構造体に設けられた底部連結部に、底板部と、この底板部から立ち上がる支持板部と、前記支持板部から内側に延びる支持爪部を形成し、この支持爪を、側部構造体の下かまちの側板部に形成されたスリットに挿入することで、底部連結部と下かまちの連結強度を高くできる。よって、コンテナ全体に歪みが生じても、下かまちが底部連結部から外れにくくなる。 Further, a bottom plate portion, a support plate portion rising from the bottom plate portion, and a support claw portion extending inward from the support plate portion are formed on the bottom connecting portion provided in the bottom structure, and the support claws are used as side portions. By inserting it into the slit formed in the side plate portion of the lower stile of the structure, the connection strength between the bottom connecting portion and the lower stile can be increased. Therefore, even if the entire container is distorted, the lower stile is less likely to come off from the bottom connecting portion.

図５（Ａ）に示すように、第１底部連結金具４０の立上り片４４には一対の規制突起４４ａが一体に形成されている。規制突起４４ａは、波板１２の上面よりも上方へ突出している。分解された底部構造体１０が複数個上下に重ねられると、規制突起４４ａが、その上に位置する底部構造体１０の下面の滑材１３に形成された穴に挿入され、または滑材１３の側部に掛止される。これにより、上下に重ねられた底部構造体１０が運搬時などに位置ずれするのを規制できる。 As shown in FIG. 5A, a pair of regulation protrusions 44a are integrally formed on the rising piece 44 of the first bottom connecting metal fitting 40. The regulation protrusion 44a projects upward from the upper surface of the corrugated plate 12. When a plurality of disassembled bottom structures 10 are stacked one above the other, the regulation protrusion 44a is inserted into a hole formed in the lubricant 13 on the lower surface of the bottom structure 10 located on the regulation protrusion 44a, or the lubricant 13 is inserted. It is hooked on the side. As a result, it is possible to prevent the bottom structures 10 stacked one above the other from being displaced during transportation or the like.

底部構造体１０の２つの第１辺部１０ａに第１側部構造体２０が取付けられ、２つの第２辺部１０ｂに第２側部構造体３０が取付けられる。第１側部構造体２０と第２側部構造体３０はどちらを先に取付けてもよいが、以下の実施の形態では、第２側部構造体３０が先に取付けられる。 The first side structure 20 is attached to the two first side portions 10a of the bottom structure 10, and the second side structure 30 is attached to the two second side portions 10b. Either the first side structure 20 or the second side structure 30 may be attached first, but in the following embodiments, the second side structure 30 is attached first.

図７に示すように、第２側部構造体３０の傾斜支柱３２，３２の下端部３２ｎ，３２ｎを、底部構造体１０の第２辺部１０ｂに固定された第２底部連結金具４５上に設置する。傾斜支柱３２，３２の下端部３２ｎ，３２ｎを、第２底部連結金具４５の支持板部４７と立上り片４９の内部に入り込ませることで、第２側部構造体３０を自立するように取り付けることができる。さらに、支持片３３ａを第２底部連結金具４５のスリット４８に内側から挿入し、図８に示すように、支持片３３ａを支持板部４７の外面で折り返すことで、第２側部構造体３０の下部と第２底部連結金具４５とを、強固に連結することができる。 As shown in FIG. 7, the lower ends 32n and 32n of the inclined columns 32 and 32 of the second side structure 30 are placed on the second bottom connecting metal fitting 45 fixed to the second side 10b of the bottom structure 10. Install. The second side structure 30 is attached so as to be self-supporting by allowing the lower ends 32n and 32n of the inclined columns 32 and 32 to enter the inside of the support plate portion 47 of the second bottom connecting bracket 45 and the rising piece 49. Can be done. Further, the support piece 33a is inserted into the slit 48 of the second bottom connecting metal fitting 45 from the inside, and as shown in FIG. 8, the support piece 33a is folded back on the outer surface of the support plate portion 47 to form the second side structure 30. The lower part of the above and the second bottom connecting metal fitting 45 can be firmly connected.

第１側部構造体２０は、底部構造体１０の第１辺部１０ａにおいてＹ方向の両端部に設けられた第１底部連結金具４０上に取付けられる。 The first side structure 20 is mounted on the first bottom connecting metal fittings 40 provided at both ends in the Y direction in the first side portion 10a of the bottom structure 10.

図６（Ａ）に示すように、第１側部構造体２０を底部構造体１０の外側に向けて傾く姿勢にして、下かまち２１の側板部２１ｂに形成されたスリット２１ｃに、第１底部連結金具４０に形成された支持爪部４３を挿入する。その後、第１側部構造体２０を、下かまち２１側を支点としてα方向へ回動させて、図６（Ｂ）に示すように第１側部構造体２０を垂直姿勢とする。 As shown in FIG. 6A, the first side structure 20 is tilted toward the outside of the bottom structure 10 and the first bottom portion is formed in the slit 21c formed in the side plate portion 21b of the lower stile 21. The support claw portion 43 formed on the connecting metal fitting 40 is inserted. After that, the first side structure 20 is rotated in the α direction with the lower stile 21 side as a fulcrum, and the first side structure 20 is in a vertical posture as shown in FIG. 6 (B).

図６（Ｂ）では、支持爪部４３がスリット２１ｃに挿入された状態で、下かまち２１の下板部２１ａが、第１底部連結金具４０の底板部４１の上に設置され、下かまち２１の側板部２１ｂが、第１底部連結金具４０の支持板部４２の内面に設置される。これにより、第１側部構造体２０は、底部構造体１０の第１辺部１０ａにおいてほぼ自立して設置される。 In FIG. 6B, with the support claw portion 43 inserted into the slit 21c, the lower plate portion 21a of the lower stile 21 is installed on the bottom plate portion 41 of the first bottom connecting metal fitting 40, and the lower stile 21 is installed. The side plate portion 21b is installed on the inner surface of the support plate portion 42 of the first bottom connecting fitting 40. As a result, the first side structure 20 is installed substantially independently on the first side portion 10a of the bottom structure 10.

底部構造体１０の第２辺部１０ｂに第２側部構造体３０を垂直姿勢で取付け、その後に第１側部構造体２０を第１底部連結金具４０に支持させて、第１側部構造体２０を、図６（Ａ）に示す倒れ姿勢から、図６（Ｂ）に示す垂直姿勢へ回動させる過程で、コンテナ１の上側角部において、第１側部構造体２０と第２側部構造体３０を連結させることができる。 The second side structure 30 is attached to the second side portion 10b of the bottom structure 10 in a vertical posture, and then the first side structure 20 is supported by the first bottom connecting metal fitting 40 to support the first side structure. In the process of rotating the body 20 from the tilted posture shown in FIG. 6 (A) to the vertical posture shown in FIG. 6 (B), at the upper corner portion of the container 1, the first side structure 20 and the second side The partial structure 30 can be connected.

第１側部構造体２０を、垂直姿勢へ向けてα方向へ回動させる過程で、図９に示す第２側部構造体３０の上かまち３１の端部を、第１側部構造体２０の上かまち２２に形成された切欠き部２２ｄの内部に挿入する。そして、図１０および図１１に示すように、第２側部構造体３０の上かまち３１の上板部３１ａを、第１側部構造体２０の外側支柱２３の上端部２３ｍと上かまち２２の上板部２２ａとの隙間Ｈに挿入する。また、第２側部構造体３０の上かまち３１の内側板部３１ｃを、第１側部構造体２０の外側支柱２３の開口部２３ｃに挿入し、上かまち３１の外側板部３１ｂを、外側支柱２３の側面２３ｂの外側に設置する。 In the process of rotating the first side structure 20 in the α direction toward the vertical posture, the end of the upper stile 31 of the second side structure 30 shown in FIG. 9 is changed to the first side structure 20. It is inserted into the notch portion 22d formed in the upper stile 22. Then, as shown in FIGS. 10 and 11, the upper plate portion 31a of the upper stile 31 of the second side structure 30 is the upper end portion 23m of the outer support column 23 of the first side structure 20 and the upper stile 22. It is inserted into the gap H with the upper plate portion 22a. Further, the inner plate portion 31c of the upper stile 31 of the second side structure 30 is inserted into the opening 23c of the outer support column 23 of the first side structure 20, and the outer plate portion 31b of the upper stile 31 is inserted outside. It is installed outside the side surface 23b of the support column 23.

この状態で、図１０と図１１に示すように、第１側部構造体２０と第２側部構造体３０の端部どうし、Ｘ方向とＹ方向およびＺ方向の各方向へ大きく位置ずれすることなく組み合わせることができる。 In this state, as shown in FIGS. 10 and 11, the ends of the first side structure 20 and the second side structure 30 are largely displaced from each other in the X, Y, and Z directions. Can be combined without any.

その後、図１０と図１１に示すように、上部連結金具５０を設置する。上部連結金具５０は、差し込み片５３を上かまち２２のスリット２２ｅに、差し込み片５４を上かまち３１のスリット３１ｅに挿入する。また、上部連結金具５０の外側支持板５１を、上かまち２２の外側板部２２ｂの外側に設置し、外側支持板５２を上かまち３１の外側板部３１ｂの外側に設置する。そして、介在片５５を、上かまち２２の内側板部２２ｃと、上かまち３１の内側板部３１ｃとの間に介在させる。 After that, as shown in FIGS. 10 and 11, the upper connecting metal fitting 50 is installed. The upper connecting metal fitting 50 inserts the insertion piece 53 into the slit 22e of the upper stile 22 and the insertion piece 54 into the slit 31e of the upper stile 31. Further, the outer support plate 51 of the upper connecting metal fitting 50 is installed outside the outer plate portion 22b of the upper stile 22, and the outer support plate 52 is installed outside the outer plate portion 31b of the upper stile 31. Then, the intervening piece 55 is interposed between the inner plate portion 22c of the upper stile 22 and the inner plate portion 31c of the upper stile 31.

さらに、対向する２つの第１側部構造体２０の上かまち２２どうしを、１本のまたは複数本の天梁６０によって連結する。 Further, the upper stiles 22 of the two opposing first side structures 20 are connected to each other by one or a plurality of ceiling beams 60.

使用後のコンテナ１を開梱するときは、天梁６０と上部連結金具５０を外して、第１側部構造体２０と第２側部構造体３０との連結を解除し、第１側部構造体２０と第２側部構造体３０を、底部構造体１０から取り外す。 When unpacking the used container 1, the ceiling beam 60 and the upper connecting metal fitting 50 are removed, the connection between the first side structure 20 and the second side structure 30 is released, and the first side portion is released. The structure 20 and the second side structure 30 are removed from the bottom structure 10.

上記実施の形態のコンテナ１は、各部材を厚みが最大で１．２ｍｍで、多くの部材を厚さ０．７ｍｍの鉄板で構成しているため、全体として軽量であり、材料費が安く、低コストで製造することが可能である。 In the container 1 of the above embodiment, each member has a maximum thickness of 1.2 mm, and many members are made of an iron plate having a thickness of 0.7 mm. Therefore, the container 1 is lightweight as a whole and the material cost is low. It can be manufactured at low cost.

比較的薄い金属板で形成されたコンテナ１は全体の剛性がやや低くなり、例えば、底部構造体１０の下面をフォークリフトの上に載せて運搬するようなときに、コンテナ１が比較的歪みやすくなっている。しかしながら、図９ないし図１１に示している第１側部構造体２０と第２側部構造体３０との連結部の連結強度が高く、また、図５と図６に示している底部構造体１０と第１側部構造体２０との連結部の連結強度が高く、さらに、図７と図８に示している底部構造体１０と第２側部構造体３０との連結強度が高い。そのため、これら連結部が外れるなどの不良が生じにくくなっている。 The overall rigidity of the container 1 formed of a relatively thin metal plate is slightly low, and the container 1 is relatively easily distorted when, for example, the lower surface of the bottom structure 10 is placed on a forklift and transported. ing. However, the connecting strength of the connecting portion between the first side structure 20 and the second side structure 30 shown in FIGS. 9 to 11 is high, and the bottom structure shown in FIGS. 5 and 6 has a high connecting strength. The connecting strength of the connecting portion between the 10 and the first side structure 20 is high, and the connecting strength between the bottom structure 10 and the second side structure 30 shown in FIGS. 7 and 8 is high. Therefore, defects such as disconnection of these connecting portions are less likely to occur.

図９ないし図１１に示す第１側部構造体２０と第２側部構造体３０の連結部では、第２側部構造体３０の上かまち３１を、第１側部構造体２０の外側支柱２３の上端部２３ｍと上かまち２２との間の隙間Ｈ内に挿入し、さらに、上かまち３１の内側板部３１ｃを第１側部構造体２０の外側支柱２３の開口部２３ｃに挿入し、上かまち３１の外側板部３１ｂを、外側支柱２３の側面２３ｂの外側に設置している。 In the connecting portion between the first side structure 20 and the second side structure 30 shown in FIGS. 9 to 11, the upper stile 31 of the second side structure 30 is used as the outer support column of the first side structure 20. It is inserted into the gap H between the upper end portion 23m of 23 and the upper stile 22, and further, the inner plate portion 31c of the upper stile 31 is inserted into the opening 23c of the outer support column 23 of the first side structure 20. The outer plate portion 31b of the upper stile 31 is installed outside the side surface 23b of the outer support column 23.

そのため、第１側部構造体２０と第２側部構造体３０が、相対的にＺ方向に位置ずれすることがなく、上部連結金具５０を嵌めこむだけで、連結部の強度を高く維持することができる。 Therefore, the first side structure 20 and the second side structure 30 are not relatively displaced in the Z direction, and the strength of the connecting portion is maintained high simply by fitting the upper connecting metal fitting 50. be able to.

また、図５と図６に示す底部構造体１０と第１側部構造体２０との連結部では、第１側部構造体２０の下かまち２１が０．７ｍｍ程度の薄い鉄板で構成されているが、それよりも厚い鉄板で構成している第１底部連結金具４０の支持爪部４３を、下かまち２１のスリット２１ｃに挿入している。そのため、コンテナ１に歪みが生じようとしても、底部構造体１０と第１側部構造体２０との連結部が外れることがない。 Further, in the connecting portion between the bottom structure 10 and the first side structure 20 shown in FIGS. 5 and 6, the lower stile 21 of the first side structure 20 is composed of a thin iron plate of about 0.7 mm. However, the support claw portion 43 of the first bottom connecting bracket 40, which is made of a thicker iron plate, is inserted into the slit 21c of the lower stile 21. Therefore, even if the container 1 is to be distorted, the connecting portion between the bottom structure 10 and the first side structure 20 will not be disengaged.

また、第２側部構造体３０は上かまち３１と２本の傾斜支柱３２だけの最少の部品で構成されて、低コストで製造することが可能になっている。しかし、上かまち３１は、図９ないし図１１に示す構造で、第１側部構造体２０の上かまち２２に強固に連結され、図７と図８に示すように、第２側部構造体３０は支持片３３ａによって第２底部連結金具４５に強固に連結されている。よって、コンテナ１に歪みが生じようとしても、底部構造体１０と第２側部構造体３０との連結部が外れることがない。 Further, the second side structure 30 is composed of the minimum number of parts of only the upper stile 31 and the two inclined columns 32, and can be manufactured at low cost. However, the upper stile 31 has the structure shown in FIGS. 9 to 11, and is firmly connected to the upper stile 22 of the first side structure 20, and as shown in FIGS. 7 and 8, the second side structure 30 is firmly connected to the second bottom connecting metal fitting 45 by the support piece 33a. Therefore, even if the container 1 is to be distorted, the connecting portion between the bottom structure 10 and the second side structure 30 will not be disengaged.

以上から実施の形態のコンテナ１は、軽量で低コストに製造でき、しかも各部材の連結部の強度が高く、運搬中などに連結部が外れるなどの不良が生じにくいものとなる。 From the above, the container 1 of the embodiment is lightweight and can be manufactured at low cost, and the strength of the connecting portion of each member is high, so that defects such as disconnection of the connecting portion during transportation are unlikely to occur.
