【０００１】
【発明の属する技術分野】
本発明は、複数枚の格子状パネルにより箱型状に組み立てられ、製品や部品を収納して搬送したり、段積みして保管するための物品収納具に関する。
【０００２】
【従来の技術】
複数の格子状パネルを箱型状に組み立て、物品を収容して搬送したり、また複数段に段積みして倉庫などに保管する物品収納具は、従来では、生産工程の簡略化から、縦線材と横線材をできるだけ等ピッチで格子状に配置して格子状パネルを形成している。そして、これら格子状パネルで強度が必要な個所は、補強線材をプラスして補強している。
【０００３】
【発明が解決しようとする課題】
ところで、近年、このような物品収納具においても、軽量化、低コスト化が求められて推進されつつある。これを実施するために、格子状パネルを部分的に径の細い線材を用いて製造することも考えられるが、通常パネル製造装置では、線材を部分的に異径の線材に変更して取り扱うことが困難なことが多く、改造するとかえって高コストになるおそれがある。
【０００４】
本発明は、上記問題点を解決して、線材により格子状パネルを形成し、これら複数の格子状パネルで構成される物品収納具において、強度の低下を防止しつつ径の小さい線材により格子状パネルを形成し、軽量化および低コスト化をはかることができる物品収納具を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために請求項１記載の発明は、縦線材と横線材からなる底面格子状パネルおよび左右の側面格子状パネルならびに前後面格子状パネルを具備し、前記底面格子状パネルに取り付けられた底部フレームに、下段に配置される物品収納具の左右の側面格子状パネルの上辺部に係合可能な係合溝を有する脚部材を取り付けて段積み可能に構成された物品収納具において、左右の側面格子状パネルの縦線材と横線材とをそれぞれ等ピッチで配置し、左右の側面格子状パネルの前辺部側と後辺部側に、補強縦線材をそれぞれ設けるとともに、これら補強縦線材のうち、上段に段積みされる物品収納具の脚部材に対応する補強縦線材の上端部を切除し、左右の側面格子状パネルの上辺部の第１段横線材と第２段横線材の間で、上端部が切除された前記補強縦線材の上部に座屈補強用横線材を取り付けたものである。
【０００６】
上記構成によれば、縦線材と横線材の径を全体に小さくして軽量化を図る時に、縦線材と横線材を等ピッチ間隔で配設する製造手順を変更することなく、補強縦線材と座屈補強用横線材とを追加する簡単な構造で、第１段横線材と補強用横線材の間の縦線材を短くして、上段物品収納具から脚部材を介して負荷される荷重に対する縦線材の座屈強度を向上させ、段積み時の強度低下を防止することができるとともに、補強縦線材の上端部が切除されることにより左右の側面格子状パネルの上辺部の厚みを小さくできて、上段の物品収納具を段積みする時の脚部材の係合溝の嵌め込みを容易に行うことができる。
【０００７】
請求項２記載の発明は、請求項１記載の構成において、左右の側面格子状パネルの後辺部縦線材と後面格子状パネルの側辺部縦線材とを回動自在に連結する連結部材を設けるとともに、左右の側面格子状パネルの第１段横線材と第２段横線材の間で前記後辺部縦線材と側辺部縦線材をそれぞれ回動自在に連結する開き止め連結部材を設け、座屈補強用横線材の後端部を、開き止め連結部材に干渉しない位置で切除したものである。
【０００８】
上記構成によれば、段積み時に左右の側面格子状パネルと後面格子状パネルの連結部を開き止め連結部材により効果的に開き止めし、補強用横線材の後端部を切除することで、開き止め連結部材との干渉なくして、上段収納具の脚部材を左右の側面格子状パネルの上辺部で良好に支持することができる。
【０００９】
請求項３記載の発明は、請求項１または２記載の構成において、補強縦線材は、前辺部から後方に２本目の縦線材との間に横線材を挟み込むように取り付けられた第１補強縦線材、前辺部から後方に４本目の縦線材との間に横線材を挟み込むように取り付けられた第２補強縦線材、後辺部から前方に４本目の縦線材との間に横線材を挟み込むように取り付けられた第３補強縦線材、および後辺部から前方に２本目の縦線材との間に横線材を挟み込むように取り付けられた第４補強縦線材からなり、上端部が切除された補強縦線材を、第１補強縦線材および第３補強縦線材としたものである。
【０００９】
請求項４記載の発明は、請求項１乃至３記載の構成において、座屈補強用横線材は、縦線材の外面または内面に取り付けられ、左右の側面格子状パネルの上辺部に、横線材とで縦線材を挟み込むように補強用横線材が取り付けられたものである。
【００１０】
【発明の実施の形態】
ここで、本発明に係る物品収納具の実施の形態を図１〜図７に基づいて説明する。
まず、この物品収納具１の概略を図６，図７を参照して説明する。
【００１１】
この物品収納具１は、底面格子状パネル２と前面格子状パネル３および後面格子状パネル４と左右の側面格子状パネル５，６とで上面が開放された箱体状に形成されている。そして、底面格子状パネル２に取り付けられた底部フレーム７の四隅位置に、左右の側面格子状パネル５，６の上辺部前後位置に係合可能な脚部材８が設けられて、物品収納具１を上下に段積み可能に構成されている。また各格子状パネル２〜６は、縦線材１１（１１Ａ，１１Ｂ）と横線材１２（１２Ａ，１２Ｂ）とがそれぞれ一定ピッチで配置されて矩形格子状に形成され、また同一径の線材により格子状パネル２〜６が成形されるとともに、後述するように、必要に応じて同一径または異径の補強線材が取り付けられている。
【００１２】
前記底面格子状パネル２の前辺部に、前底部ヒンジコイル（連結部材）９Ａを介して前面格子状パネル３が回動自在に連結され、前面全体を開閉することができる。また、前面格子状パネル３は、高さ方向の中間位置で分離されて、下部が底面格子状パネル２側に折り曲げられたＬ字形の下段パネル部３ａと、上段パネル部３ｂとで構成されている。そして下段パネル部３ａと上段パネル部３ｂとは、前部ヒンジコイル（連結部材）９Ｂにより互いに回動自在に連結され、上段パネル部３ｂを前方に回動することにより前面上半分を開閉することができる。また下段パネル部３ａと上段パネル部３ｂは、上連結具１０Ａと下連結具１０Ｂにより、それぞれ側面格子状パネル５，６の前辺部に着脱自在に係止されている。
【００１３】
前記底面格子状パネル２の後辺部には、後底部ヒンジコイル（連結部材）９Ｃを介して後面格子状パネル４が回動自在に連結されて折り畳み可能に構成されている。さらに後面格子状パネル４の左右両辺部にそれぞれ側部ヒンジコイル（連結部材）９Ｄ，９Ｅを介して左右の側面格子状パネル５，６が回動自在に連結されて折り畳み可能に構成されている。
【００１４】
底面格子状パネル２の底部に配置された底部フレーム７は、たとえば上面が開放されたチャネル形断面の複数の型材を組み合わせて構成され、前後枠部材２１Ｆ，２１Ｂと左右枠部材２１Ｒ，２１Ｌで囲まれた枠フレーム２１と、該枠フレーム２１内で左右枠部材２１Ｒ，２１Ｌ間に掛け渡された複数の中間梁材２２Ａ〜２２Ｃとを具備している。また左右枠部材２１Ｒ，２１Ｌの前後位置に脚部材８がそれぞれ取り付けられ、これら脚部材８の下面には、下段物品収納具１の側面格子状パネル５，６の上辺部に係合可能な係合溝８ａが形成されている。
【００１５】
次に側面格子状パネル５，６の構造について図１〜図３を参照して説明する。
側面格子状パネル５，６は、等ピッチで配置された縦線材１１Ａの内面に各横線材１２Ａが後辺部を除いて等ピッチで配置されて交差部がそれぞれ溶接により接合されている。そして側面格子状パネル５，６の上辺部内面に、横線材１２Ａとの間に縦線材１１Ａを挟み込む補強用横線材１３が取り付けられている。また横線材１２Ａの外面には、縦線材１１Ａとの間に横線材１２Ａを挟み込むように、図１にハッチングで示す複数の補強縦線材１４Ａ〜１４Ｄがそれぞれ縦線材１１Ａに重なり合う位置に取り付けられている。
【００１６】
これら４本の補強縦線材１４Ａ〜１４Ｄは、たとえば前辺部から後方に２本目の縦線材１１Ａとの間に横線材１２Ａを挟み込むように第１補強縦線材１４Ａが取り付けられ、また前辺部から後方に４本目の縦線材１１Ａとの間に横線材１２Ａを挟み込む位置に第２補強縦線材１４Ｂが取り付けられている。さらに後辺部から前方に４本目の縦線材１１Ａとの間に横線材１２Ａを挟み込む位置に第３補強縦線材１４Ｃが取り付けられ、さらにまた後辺部から前方に２本目の縦線材１１Ａとの間に横線材１２Ａを挟み込む位置に第４補強縦線材１４Ｄが取り付けられている。また側面格子状パネル５，６の前辺部には、連結具９Ａ，９Ｂを構成する横置きＵ字形の被係合部材９ａ，９ｂと、下部で連結部の開き止めをする横置きＵ字形の開き止め部材１８が取り付けられ、また底辺部には、前後位置に左右枠部材２１Ｒ，２１Ｌに嵌合する係止部材１９がそれぞれ突設されている。
【００１７】
ところで、上記物品収納具１を軽量化する場合、物品収納具１内に収容する荷の重量を保持できる範囲で、全体を構成する線材の径を小さくすることにより大幅な軽量化が可能となるが、とりわけ問題となるのは、段積み時の側面格子状パネル５，６の座屈強度である。特に脚部材８が係合される側面格子状パネル５，６の上辺部の前部と後部において縦線材１１Ａに座屈が発生するおそれがある。
【００１８】
ここで、補強縦線材を追加することにより補強することも考えられるが、脚部材８の係合溝８ａの幅に対して、側面格子状パネル５，６の上辺部の厚みが大きくなると、段積み時の嵌め込みが困難になる恐れがある。このため、第１補強縦線材１４Ａと第３強縦線材１４Ｃの上端部が第２段横線材１３Ａｂ位置で切断されて切除されている。したがって、脚部材８が係合される上辺部では、新たな補強縦線材を追加しても座屈強度を高めることはできない。
【００１９】
このため、この実施の形態では、上辺部の第１段横線材１２Ａａとその下の第２段横線材１２Ａｂの中間位置で、図２（ｂ）に示す縦線材１１Ａの外面、または図２（ｂ）に示す縦線材１１Ａの内面に、１本の座屈補強用横線材１５が取り付けられ、たとえば第１段横線材１２Ａａと座屈補強用横線材１５の間および座屈補強用横線材１５と第２段横線材１２Ａｂの間が、等ピッチＰａに対して略１／２のピッチＰａ１に設定されている。この座屈補強用横線材１５により、上段物品収納具１の脚部材８Ａ，８Ｄが係止される係止部の前後位置で、荷重を支持する縦線材１１Ａの第１段横線材１２Ａａから座屈補強用横線材１５までの長さ（ピッチＰａ１）を、略１／２にすることにより、極めて簡易な構造で座屈強度を高めることができる。
【００２０】
また、側面格子状パネル５，６の後辺部の縦線材１１Ａと後面格子状パネル４の左右側辺部の縦線材１１とを連結する側部ヒンジコイル９Ｄ，９Ｅの上部には、段積み時の荷重による開きを防止するためのたとえば略長円形断面の開き止め連結部材１６が取り付けられており、この開き止め連結部材１６は、上端側の第１段横線材１２Ａａと第２段横線材１２Ａｂの間に位置している。このため、座屈補強用横線材１５の後端部を、後辺部から２番目の縦線材１２Ａ（第４補強縦線材１５Ｄ）に対応する切断部１５ａで切除することにより、座屈補強用横線材１５と開き止め連結部材１６との干渉が防止されている。
【００２１】
また、上記側面格子状パネル５，６の変形例として、図８に示すように、第２段横線材１２Ａｂを上方に変位させて固着し、第１段横線材１２Ａａと第２段横線材１２ＡｂのピッチＰａ２を小さくすることで、極めて簡易な構造で座屈強度を高めることができる。第２段横線材１２Ａｂと第３段横線材１２ＡｃのピッチＰａ３とすると、たとえばＰａ：Ｐａ２：Ｐａ３≒１：１．４：０．６に設定されている。
【００２２】
さらに上記物品収納具１を軽量化する場合、過大な強度部分を少なくすることでこれを実現することができる。
【００２３】
すなわち、底面格子状パネル２では、縦線材１１Ｂと横線材１２Ｂとをそれぞれ前辺部と後辺部を除いて、等ピッチＰｂで配置した格子状を基本形状としているが、ここでは、中間梁材２２Ａ〜２２Ｃ上に底面格子状パネル２の縦線材１２Ｂが接近した位置または近傍位置に配置されることから、必要以上に過大な強度を有している。
【００２４】
したがって、前部の中間梁材２２Ａおよび後部の中間梁材２２Ｃに対応する図５（ｂ）に仮想線で示す横線材１２Ｃが削除され、削除部分の前後の横線材１２ＢのピッチＰｂ１が等ピッチＰｂの２倍に形成されている。また、中央部の中間梁材２２Ｂに対応して前後に配置される図５（ｂ）に仮想線で示す２本の横線材１２Ｄを１本に減らして、横線材１２Ｂａを中間位置に配置し、前後の横線材１２ＢのピッチＰｂ２を等ピッチＰｂの１．５倍に構成している。
【００２５】
これにより、物品収納具１の底面の強度を低下させることなく、合計３本の横線材１２Ｂを削除して、材料コストを低減するとともに、軽量化を促進することができる。
【００２６】
上記実施の形態によれば、格子状パネル２〜６の縦線材１１と横線材１２の外径を全体的に小さくして軽量化を図る時に、左右の側面格子状パネル５，６の縦線材１１Ａと横線材１２Ａを等ピッチ間隔で配設する製造手順を変更することなく、補強用横線材１３を追加する簡単な構造で、第１段横線材１２Ａａと補強用横線材１３の間の縦線材１１Ａを短くして、上段の物品収納具１から脚部材８Ａ，８Ｂを介して負荷される荷重に対する座屈強度を向上させ、段積み時の強度低下を防止することができる。
【００２７】
また、格子状パネル２〜６の縦線材１１と横線材１２の径を全体的に小さくして軽量化を図る時に、左右の側面格子状パネル５，６の第１段横線材１２Ａａと第２段横線材１２Ａｂのピッチを小さくした簡単な構造で、第１段横線材１２Ａａと第２段横線材１２Ａｂの間の縦線材１１Ａを短くして、上段物品収納具１から脚部材８Ａ，８Ｂを介して負荷される荷重に対する座屈強度を向上させ、段積み時の強度低下を防止することができる。
【００２８】
さらに、格子状パネル２〜６の縦線材１１と横線材１２の径を全体的に小さくして軽量化を図る時に、底部フレーム７の中間梁材２２Ａ〜２２Ｃにより支持される底面格子状パネル２の横線材１２Ｃ，１２Ｄを削除し、粗いピッチとすることにより、必要な強度を確保しつつ部材の削減が図れ、軽量化を促進することができる。
【００２９】
なお、上記実施の形態では、縦線材１１（１１Ａ，１１Ｂ）と横線材１２（１２Ａ，１２Ｂ）を同一径として説明したが、パネル製造装置の仕様によっては、縦線材１１（１１Ａ，１１Ｂ）と横線材１２（１２Ａ，１２Ｂ）とを異径の線材としたり、また部分的に径の異なる線材を使用することもできる。
【００３０】
【発明の効果】
以上に述べたごとく請求項１記載の発明によれば、縦線材と横線材の径を全体に小さくして軽量化を図る時に、縦線材と横線材を等ピッチ間隔で配設する製造手順を変更することなく、補強縦線材と座屈補強用横線材とを追加する簡単な構造で、第１段横線材と補強用横線材の間の縦線材を短くして、上段物品収納具から脚部材を介して負荷される荷重に対する縦線材の座屈強度を向上させ、段積み時の強度低下を防止することができるとともに、補強縦線材の上端部が切除されることにより左右の側面格子状パネルの上辺部の厚みを小さくできて、上段の物品収納具を段積みする時の脚部材の係合溝の嵌め込みを容易に行うことができる。
【００３１】
請求項２記載の発明によれば、段積み時に左右の側面格子状パネルと後面格子状パネルの連結部を開き止め連結部材により効果的に開き止めし、補強用横線材を切除することで、開き止め連結部材との干渉なくして、上段収納具の脚部材を左右の側面格子状パネルの上辺部で良好に支持することができる。

The locking member 18 is attached to the bottom side portion, and locking members 19 that are fitted to the left and right frame members 21R and 21L are projected from the front and rear positions, respectively.
[0017]
By the way, when the article storage tool 1 is reduced in weight, it is possible to significantly reduce the weight by reducing the diameter of the wire constituting the whole as long as the weight of the load stored in the article storage instrument 1 can be maintained. However, the problem is the buckling strength of the side grid panels 5 and 6 at the time of stacking. In particular, buckling may occur in the vertical wire 11A at the front and rear portions of the upper side portions of the side lattice panels 5 and 6 with which the leg members 8 are engaged.
[0018]
Here, it is conceivable to reinforce by adding a reinforcing vertical wire, but if the thickness of the upper side portion of the side lattice panels 5 and 6 becomes larger than the width of the engaging groove 8a of the leg member 8, There is a risk that it will be difficult to fit in the stack. Therefore, the upper end portion of the first reinforcing vertical wire 14A and the third Tsuyotate wire 14C is truncated is cut by the second-stage horizontal member 13Ab position. Therefore, at the upper side where the leg member 8 is engaged, the buckling strength cannot be increased even if a new reinforcing vertical wire is added.
[0019]
For this reason, in this embodiment, the outer surface of the vertical wire 11A shown in FIG. 2 (b) or the outer surface of the first horizontal wire 12Aa on the upper side and the second-stage horizontal wire 12Ab below it, or FIG. A single buckling reinforcing horizontal wire 15 is attached to the inner surface of the vertical wire 11A shown in b), for example, between the first-stage horizontal wire 12Aa and the buckling reinforcing horizontal wire 15 and the buckling reinforcing horizontal wire 15. And the second-stage horizontal wire 12Ab are set to a pitch Pa1 that is substantially ½ of the equal pitch Pa. The buckling reinforcing horizontal wire 15 is seated from the first horizontal wire 12Aa of the vertical wire 11A that supports the load at the front and rear positions of the locking portion where the leg members 8A and 8D of the upper article storage tool 1 are locked. By making the length (pitch Pa1) to the horizontal wire 15 for bending reinforcement substantially ½, the buckling strength can be increased with an extremely simple structure.
[0020]
In addition, stacked on top of the side hinge coils 9D and 9E that connect the vertical wires 11A on the rear sides of the side grid panels 5 and 6 and the vertical wires 11 on the left and right sides of the rear grid panel 4 are stacked. For example, an opening connecting member 16 having a substantially oval cross section is attached to prevent the opening due to a load at the time. The opening connecting member 16 includes a first-stage horizontal wire 12Aa and a second-stage horizontal wire on the upper end side. Located between 12 Abs. Therefore, by excising a cutting portion 15a corresponding to the rear end of the seat屈補strong for horizontal member 15, from the rear side portion to the second longitudinal wire 12A (fourth reinforcing vertical wire 15D), the seat屈補for strong Interference between the horizontal wire 15 and the stopper connection member 16 is prevented.
[0021]
As a modification of the side grid panels 5 and 6, as shown in FIG. 8, the second-stage horizontal wire 12Ab is displaced and fixed upward, and the first-stage horizontal wire 12Aa and the second-stage horizontal wire 12Ab are fixed. by reducing the pitch Pa2, as possible out to increase the buckling strength in a very simple structure. When the pitch Pa3 between the second-stage horizontal wire 12Ab and the third-stage horizontal wire 12Ac is set, for example, Pa: Pa2: Pa3≈1: 1.4: 0.6.
[0022]
Further, when the article storage device 1 is reduced in weight, this can be realized by reducing an excessive strength portion.
[0023]
That is, in the bottom lattice-like panel 2, the basic shape is a lattice shape in which the vertical wire 11B and the horizontal wire 12B are arranged at an equal pitch Pb except for the front side portion and the rear side portion, respectively. Since the vertical wires 12B of the bottom grid-like panel 2 are arranged on the materials 22A to 22C at close positions or in the vicinity thereof, the strength is excessively high.
[0024]
Therefore, the horizontal wire 12C indicated by the phantom line in FIG. 5B corresponding to the front intermediate beam member 22A and the rear intermediate beam member 22C is deleted, and the pitch Pb1 of the horizontal wire 12B before and after the deleted portion is equal pitch. It is formed twice as much as Pb. Further, the two horizontal wires 12D indicated by the phantom lines in FIG. 5 (b) arranged corresponding to the intermediate beam 22B at the center are reduced to one, and the horizontal wire 12Ba is arranged at the intermediate position. The pitch Pb2 of the front and rear horizontal wires 12B is configured to be 1.5 times the equal pitch Pb.
[0025]
Thereby, without reducing the intensity | strength of the bottom face of the article | item storage tool 1, a total of three horizontal wire 12B can be deleted, and while reducing material cost, weight reduction can be accelerated | stimulated.
[0026]
According to the above embodiment, when achieving an overall smaller to reduce the weight of the outer diameter of the vertical wires 11 and horizontal member 12 of the grid-shaped panel 2-6, the longitudinal wires of the right and left side grid-like panels 5,6 11A and the horizontal wire 12A are arranged at equal pitch intervals without changing the manufacturing procedure, and with a simple structure in which the horizontal wire 13 for reinforcement is added, the vertical line between the first-stage horizontal wire 12Aa and the horizontal wire 13 for reinforcement 13 is added. The wire rod 11A can be shortened to improve the buckling strength against the load applied from the upper article storage device 1 via the leg members 8A and 8B, and prevent the strength from being lowered during stacking.
[0027]
Further, the diameter of the vertical wires 11 and horizontal member 12 of the grid-shaped panel 2-6 when achieve overall reduced to lighter, first stage horizontal member 12Aa of the right and left side grid-like panels 5, 6 and the second With a simple structure in which the pitch of the step horizontal wire 12Ab is reduced, the vertical wire 11A between the first step horizontal wire 12Aa and the second step horizontal wire 12Ab is shortened, and the leg members 8A, 8B are removed from the upper article storage tool 1. The buckling strength with respect to the load loaded via can be improved, and the strength reduction at the time of stacking can be prevented.
[0028]
Further, the bottom grid panel 2 supported by the intermediate beam members 22A to 22C of the bottom frame 7 when reducing the overall diameter of the vertical wires 11 and the horizontal wires 12 of the grid panels 2 to 6 and reducing the weight. By removing the horizontal wires 12C and 12D and making the pitch coarse, it is possible to reduce the number of members while ensuring the required strength, and to promote weight reduction.
[0029]
