Description

【０００１】
【発明の属する技術分野】
この発明は、各種の物品をフォークリフトによる荷扱いが可能に収容するボックスパレットに係り、更に言えば、物品の輸送後は四辺の各面板をパレット台から外して解体でき、小さな嵩にして返送時の効率を高められ、再び物品を収納するときには各面板を強固な剛構造に組み立て得る、組立式ボックスパレットの技術分野に属する。
【０００２】
【従来の技術】
従来、上述の如き組立式ボックスパレットは、例えば特公昭５７−３０７３５号、特開平９−６６９３９号公報等に記載されて種々公知、周知に属する。
【０００３】
従来一般の組立式ボックスパレットは、平面が矩形をなすパレット台の四辺に沿って正面板と背面板及び左右の側面板を解体可能な箱型に組み立てて構成される。各面板の下部は、例えばパレット台に鍵孔状に設けた止め孔へ、面板下部へ突出させたリベットを差し込む手法などで比較的簡単に強固に止められる。しかし、正面板又は背面板と左右の側面板とが交わるコーナー部の上部の結合を簡単にしかも強固な剛構造に行う手段の開発に種々な苦心がなされている。
【０００４】
というのも、組立式ボックスパレットの宿命として、物品の輸送後には四辺の各面板をパレット台から外して解体し、できるだけ小さな嵩にして返送時の効率を高めることが強く要求される。返送時の形態は、例えば図９に例示したように解体しない一つのボックスパレットａのボックスｂ内に、他の解体した組立式ボックスパレット複数個分の各面板ｃ，ｄを整然と効率よく詰め込む方式、或いは解体した面板をパレット台の上に平たく積み重ねて梱包する方式などを適宜選択して実施される。
【０００５】
そこで前者の方式を実行するときは、面板の両側縁に出っ張る物があると、箱ｂへの詰め込み作業に邪魔になって不都合である。また、前者、後者いずれの方式を実行するときでも、面板の厚さの範囲外へ突き出る物を無くすることが強く要望される。
【０００６】
従って、組立式ボックスパレットの特に正面板又は背面板と左右の側面板とが交わるコーナー部の上部を結合する組立手段に関しては、各面板の両側縁に出っ張る物がない条件を満たすことが強く要望される。
【０００７】
【本発明が解決しようとする課題】
よって、本発明の目的は、正面板又は背面板と左右の側面板とが交わるコーナー部の上部を結合する組立手段に関して、各面板の両側縁に出っ張る物がないこと、しかも各面板の最大厚さは例えば２０mm位に制限した構成で実施可能に改良した組立式ボックスパレットを提供することである。
【０００８】

請求項２記載の発明に係る組立式ボックスパレットは、
平面が矩形をなすパレット台の四辺に沿って正面板と背面板及び左右の側面板を解体可能に組み立てて構成される組立式ボックスパレットにおいて、
正面板又は背面板と左右の側面板とが交わるコーナー部の上部における一方の面板に、水平方向にスライドし、回転もするラッチ棒が設置され、該ラッチ棒の先端部は他方の面板を止めるべくほぼ直角に曲げた爪部に形成されていること、

【００１１】
【発明の実施の形態】
図１〜図７に、請求項１及び２に記載した発明に係る組立式ボックスパレットの第１の実施形態を示している。
【００１２】
この組立式ボックスパレットは、図１と図２で明らかなように、平面が矩形をなすパレット台１の四辺に沿って正面板２と背面板３及び左右の側面板４、５を解体可能な箱型に組み立てて構成される。因みに、当該ボックスパレットの大きさの一例を示すと、正面を示した図２の左右方向（長手方向）の寸法が１５００mm弱で、高さ寸法は１０００mm余、そして、短手寸法は１１００mm余である。
【００１３】
パレット台１の四辺に沿って正面板２と背面板３及び左右の側面板４、５の下部を解体可能に組み立てる手段について詳しく説明することは省くが、上述した従来一般の手段、例えば各面板の下部は、パレット台に鍵孔状に設けた止め孔へ、面板下部へ突出させたリベットを差し込む手法などが実施される。
【００１４】
次に、正面板２又は背面板３と左右の側面板４、５とが交わるコーナー部の上部を結合する組立手段として、一方の面板、図示した実施形態の場合は正面板２に、水平方向にスライドし、回転もするラッチ棒１５が、同正面板２の外面へ固着した軸受板６に支持された形で設置されている。ラッチ棒１５は外径が９mm程度の鋼棒で作られており、その先端部は長さにして１７mmぐらいの範囲が、他方の面板を止めるべくほぼ直角に曲げた爪部１５ａに形成されている。
【００１５】
前記ラッチ棒１５を使用者が手動操作するハンドル７は、図示例の場合はやはり鋼棒をコ字形に加工した形状とされ、その両端部がラッチ棒１５へ垂れ下がり状態に溶接で取り付けられている。このハンドル７が図３及び図７のように垂れ下ったとき、前記爪部１５ａは図４のように垂直線から一定の角度θだけ傾くが、正面板２のコーナー部に位置する角管支柱２ａの幅寸内にきっちり納る方向に曲げられている。
【００１６】
当該正面板２の外面には、前記ハンドル７の前進位置及び後退位置を規定する一定高さの位置決めストッパ８、９が設けられている。この位置決めストッパ８、９の背の高さ（一例として１６mm）をはじめとして、上記のラッチ棒１５とその爪部１５ａ及び軸受板６、並びにハンドル７はいずれも、正面板２の実質厚さｔ（≒１９mm）の範囲内に納まる形状、構造とされている（図７参照）。
【００１７】
当該正面板２のコーナー部に位置する角管状支柱２ａの外側面（図３の左端面）に、前記ラッチ棒１５の爪部１５ａを通過させ得る形状、大きさの通し長孔１０が、前記ハンドル７が前記位置決めストッパ８又は９の背丈を乗り越える高さまで回転された際の角度θ（図３の場合θ≒１５゜）と一致する向きに形成されている。
【００１８】
つまり、通し長孔１０は、図４のように角管状支柱２ａの上記幅寸（≒１９mm）の限度内で垂直方向上向きに形成することにより、前述した長さ（≒１７mm）の爪部１５ａを楽に通す形状、大きさで設けることができる。そして、ハンドル７を前記位置決めストッパ８又は９の背丈を乗り越える高さ（前記の角度θ）まで回転すると、爪部１５ａと通し長孔１０の向きが一致して、爪部１５ａを通し長孔５ａの内外へ出し入れすることができる。
【００１９】
しかも、当該正面板２のコーナー部の管状支柱２ａの外側面に垂直方向上向きに形成された通し長孔１０と、ラッチ棒１５の爪部１５ａを角管状支柱２ａの中空部内に納め、ハンドル７を後退位置の位置決めストッパ９に納めて垂れ下がらせた際の爪部１５ａの向きとは、図４に示したように若干の角度θだけずれる構成とされている（図４の場合でθ≒１５゜）。そのため爪部１５ａを角管状支柱２ａの中空部内に納めると、以後ラッチ棒１５がむやみと出入りする（ずり動く）不都合は生じない。ハンドル７の前記垂れ下がり位置をきっちり規制するために、前後の位置決めストッパ８、９には、ハンドル固定用の凸部１２が設けられている。
【００２０】
他方の面板、本実施形態では左側の側面板４のコーナー部材４ａは、本実施例の場合、正面板２のコーナー部外側に被さるアングル形状の部材で構成されている。このコーナー部材４ａには、前記ラッチ棒１５が水平方向にスライドすると突き当たる位置を基点（一端の半円部の中心）とする長円形状の止め用長孔１１が、前記の爪部１５ａを通過させ得る形状、大きさで、且つ前記ハンドル７でラッチ棒１５を前記θプラス９０°回転する角度αの位置（図６の角度θ＋αの位置）に、爪部１５ａと一致する水平横向きに形成されている。
【００２１】
したがって、本発明の場合、使用者がボックスパレットを組み立てるにあたっては、ハンドル７の操作でラッチ棒１５を前方へ突き出させ、その先端部の爪部１５ａを他方の面板（左側の側面板４）のコーナー部材４ａに設けてある止め用長孔１１へ通し、ハンドル７を前進位置の位置決めストッパ８へ図３のように納めることにより、隣合う二つの面板２、４のコーナー部を結合する組立てが行われる。逆に爪部１５ａを止め用長孔１１から離脱、後退させることによって二つの面板相互の解体が行われる。こうした解体時には更に、爪部１５ａを当該正面板２の角管状支柱５ａの外側面の通し長孔１０にも通して同角管状支柱２ａの中空部内にまで引き込んで納める（図３の点線図示を参照）。そして、ハンドル７を後退位置の位置決めストッパ９へ納めることにより、当該正面板２は両側縁に出っ張る物がないように返送の準備が整えられる。
【００２２】
なお、前記コーナー部材４ａに設ける止め用長孔１１の角度は、図６に示す水平横向きの角度に限らない。図７に例示したように、ハンドル７を、前記θの回転角度を起点として、正面板２の上縁材２ｂに突き当る位置まで回転する角度βの範囲内であれば、いずれの角度にも設けて実施することができる。
【００２３】
図８は、左側の側面板４のコーナー部材４ａに、止め用長孔１１が、水平ではなく、少し左斜め上向きに形成された実施形態を示している。
【００２４】
【本発明が奏する効果】
請求項１及び２記載の発明に係る組立式ボックスパレットによれば、正面板又は背面板と左右の側面板とが交わるコーナー部の上部を結合する組立手段に関して、解体した各面板の両側縁に出っ張る物がない状態を実現できる。また、各面板の最大厚さを例えば２０mm位に制限した構成の範囲内でも十分に実施可能な構成である。よって組立式ボックスパレットの用途、機能を十分に発揮させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a box pallet that accommodates various articles so that they can be handled by a forklift, and more specifically, after transportation of the articles, the four side plates can be detached from the pallet table and disassembled, and returned in a small volume. It belongs to the technical field of assembling box pallets, in which each face plate can be assembled into a strong rigid structure when goods are stored again.
[0002]
[Prior art]
Conventionally, the assembly type box pallet as described above is described in, for example, Japanese Patent Publication No. 57-30735, Japanese Patent Application Laid-Open No. 9-66939, and the like and is well known and well known.
[0003]
2. Description of the Related Art A conventional assembling box pallet is configured by assembling a front plate, a back plate, and left and right side plates into a box shape that can be disassembled along four sides of a pallet base having a rectangular plane. The lower part of each face plate can be fixed firmly and relatively easily by, for example, a method of inserting a rivet projected to the lower part of the face plate into a stop hole provided in a key hole shape on the pallet table. However, various efforts have been made to develop means for easily joining the upper portion of the corner portion where the front plate or the rear plate intersects with the left and right side plates into a rigid structure.
[0004]
This is because the fate of the assembly-type box pallet is strongly required to remove the four side plates from the pallet table and dismantle them after the transportation of the goods to make it as small as possible to increase the efficiency of the return. For example, as shown in FIG. 9, the return form is a system in which the face plates c and d corresponding to a plurality of other disassembled box pallets are packed in a box b of one box pallet a that is not dismantled in an orderly and efficient manner. Alternatively, a method of appropriately stacking and packing the disassembled face plate on a pallet table and carrying it out is carried out.
[0005]
Therefore, when the former method is executed, if there are objects protruding on both side edges of the face plate, it is inconvenient for the packing work into the box b. Moreover, it is strongly desired to eliminate an object that protrudes outside the range of the thickness of the face plate when performing either the former method or the latter method.
[0006]
Therefore, as for the assembly means for connecting the upper part of the corner portion where the front plate or the back plate and the left and right side plates cross each other, it is strongly desired to satisfy the condition that there are no protrusions on both side edges of each face plate. Is done.
[0007]
[Problems to be solved by the present invention]
Therefore, an object of the present invention is that there is no protrusion on both side edges of each face plate with respect to the assembly means for joining the upper part of the corner portion where the front plate or the back plate and the left and right side plates intersect, and the maximum thickness of each face plate. For example, the present invention is to provide an assembly box pallet which can be implemented with a configuration limited to about 20 mm.

DETAILED DESCRIPTION OF THE INVENTION
1 to 7 show a first embodiment of a prefabricated box pallet according to the first and second aspects of the present invention.
[0012]
As can be seen in FIGS. 1 and 2, the assembly-type box pallet can disassemble the front plate 2, the back plate 3, and the left and right side plates 4, 5 along the four sides of the pallet base 1 having a rectangular plane. Assembled in a box shape. By the way, the example of the size of the box pallet is as follows. The horizontal dimension (longitudinal direction) in FIG. 2 showing the front is less than 1500 mm, the height dimension is about 1000 mm, and the short dimension is about 1100 mm. is there.
[0013]
A detailed description of means for assembling the lower portions of the front plate 2, the rear plate 3, and the left and right side plates 4, 5 along the four sides of the pallet stand 1 will be omitted, but the above-described conventional general means, for example, each face plate, is omitted. For example, a method of inserting a rivet that protrudes toward the lower portion of the face plate into a stop hole provided in the shape of a key hole on the pallet base is implemented.
[0014]
Next, as an assembling means for connecting the upper part of the corner portion where the front plate 2 or the back plate 3 and the left and right side plates 4 and 5 intersect, in the horizontal direction on one face plate, in the case of the illustrated embodiment, the front plate 2 A latch rod 15 that slides and rotates is mounted on a bearing plate 6 fixed to the outer surface of the front plate 2. The latch bar 15 is made of a steel bar having an outer diameter of about 9 mm, and the tip part of the latch bar 15 has a length of about 17 mm and is formed on a claw part 15a bent almost at right angle to stop the other face plate. Yes.
[0015]
In the illustrated example, the handle 7 for the user to manually operate the latch bar 15 has a U-shaped steel bar, and both ends thereof are attached to the latch bar 15 by welding. . When the handle 7 hangs down as shown in FIGS. 3 and 7, the claw portion 15a is inclined at a certain angle θ from the vertical line as shown in FIG. It is bent in a direction that fits exactly within the width of 2a.
[0016]
On the outer surface of the front plate 2, positioning stoppers 8 and 9 having a predetermined height for defining the forward and backward positions of the handle 7 are provided. In addition to the height of the positioning stoppers 8 and 9 (16 mm as an example), the latch rod 15, its claw portion 15 a, the bearing plate 6, and the handle 7 all have a substantial thickness t of the front plate 2. The shape and structure fall within the range of (≈19 mm) (see FIG. 7).
[0017]
A through hole 10 having a shape and a size that allows the claw portion 15a of the latch rod 15 to pass through the outer side surface (left end surface in FIG. 3) of the rectangular tubular column 2a located at the corner portion of the front plate 2 The handle 7 is formed in a direction that coincides with an angle θ (θ≈15 ° in the case of FIG. 3) when the handle 7 is rotated to a height over the height of the positioning stopper 8 or 9.
[0018]
In other words, through the elongated hole 10, the nail of the and Turkey be formed vertically upwards within the limits of the width dimension of the corner tubular strut 2a (≒ 19 mm) as shown in FIG. 4, the length described above (≒ 17 mm) It can be provided in a shape and size that allows the portion 15a to pass easily. Then, when the handle 7 is rotated to a height (above the angle θ) that overcomes the height of the positioning stopper 8 or 9, the direction of the claw portion 15a and the through long hole 10 coincides, and the claw portion 15a passes through the long hole 5a. Can be taken in and out of
[0019]
In addition, the through hole 10 formed vertically upward on the outer surface of the tubular column 2a at the corner of the front plate 2 and the claw portion 15a of the latch rod 15 are accommodated in the hollow portion of the rectangular column 2a, and the handle 7 the the direction of the claw portions 15a at the time of not sag pay the positioning stopper 9 of the retracted position, in the case of a slight angle theta shift is the configuration (FIG. 4, as shown in FIG. 4 theta ≒ 15 °). Therefore, when the claw portion 15a is stored in the hollow portion of the rectangular tubular column 2a, there will be no inconvenience that the latch rod 15 will go in and out (slidably move) thereafter. In order to precisely regulate the hanging position of the handle 7, the front and rear positioning stoppers 8 and 9 are provided with convex portions 12 for fixing the handle.
[0020]
The corner plate 4a of the other side plate, that is, the left side plate 4 in this embodiment is formed of an angle-shaped member that covers the outside of the corner portion of the front plate 2 in this embodiment. In this corner member 4a, an oblong stopper long hole 11 having a base point (center of a semicircular portion at one end) where the latch rod 15 abuts when sliding horizontally is passed through the claw portion 15a. The latch rod 15 is rotated by θ + 90 ° with the handle 7 at an angle α position (the angle θ + α position in FIG. 6), which has a shape and size that can be made, and is formed in a horizontal horizontal direction that coincides with the claw portion 15a. ing.
[0021]
Therefore, in the case of the present invention, when the user assembles the box pallet, the latch rod 15 is protruded forward by the operation of the handle 7, and the claw portion 15a at the tip end portion of the other face plate (the left side plate 4). By passing the handle 7 through the stopper slot 11 provided in the corner member 4a and placing the handle 7 into the positioning stopper 8 at the forward position as shown in FIG. 3, the assembly of connecting the corner portions of the two adjacent face plates 2 and 4 is performed. Done. On the contrary, the two face plates are disassembled by separating and retracting the claw portion 15a from the long slot 11 for stopping. At the time of such disassembly, the claw portion 15a is further passed through the through long hole 10 on the outer side surface of the rectangular tubular column 5a of the front plate 2 and retracted into the hollow portion of the rectangular tubular column 2a (see the dotted line in FIG. 3). reference). Then, by placing the handle 7 in the positioning stopper 9 at the retracted position, the front plate 2 is prepared for return so that there is no object protruding on both side edges.
[0022]
In addition, the angle of the long hole 11 for a stop provided in the said corner member 4a is not restricted to the angle of horizontal horizontal direction shown in FIG. As illustrated in FIG. 7, any angle can be used as long as the handle 7 is within the range of the angle β that rotates from the rotation angle of θ to the position where it abuts against the upper edge material 2 b of the front plate 2. It can be implemented.
[0023]
FIG. 8 shows an embodiment in which the long slot 11 for stopping is formed in the corner member 4a of the left side plate 4 in a slightly diagonally upward left direction rather than horizontally.

Claims

In an assembly box pallet constructed by assembling a front plate, a rear plate and left and right side plates so that they can be disassembled along the four sides of a pallet base having a rectangular plane,
A latch bar that slides and rotates horizontally is installed on one face plate at the upper part of the corner where the front plate or the back plate and the left and right side plates intersect, and the tip of the latch rod stops the other face plate. It is formed on the claw part bent almost at right angles as much as possible,
It said handle for manually operating the latch bar is mounted in a state hanging the latch bar, the outer surface position-decided Me stopper you define the advanced position and the retracted position of the handle on the said surface plate is provided,
A through hole having a shape and a size that allows the claw portion of the latch bar to pass through the outer surface of the tubular column at the corner of the face plate is within the width of the tubular column, and the handle is the positioning stopper. is formed in a substantially perpendicular way improved orientation that matches the angle when rotated to a height to overcome back things,
The corner member of the other face plate has a stop slot that is based on the abutting position of the latch bar, and has a shape and size that allows the claw part to pass through, and within the angle range in which the handle rotates the latch bar. that it is formed substantially in a horizontal direction transverse orientation to match the parts,
The latch rod is protruded, the claw portion at the tip of the latch rod is passed through the stop slot of the corner member of the other face plate, and the two face plates are combined with the handle placed in the positioning stopper at the forward position. On the contrary, the claw part is detached from the long hole for stopping and retracted to disassemble the face plates, and the claw part is also passed through the long hole on the outer surface of the tubular column of the face plate and stored in the hollow part of the tubular column. An assembly-type box pallet characterized in that the handle is housed in a positioning stopper in the retracted position.
