Description

本発明は、折り畳み可能な物品収納容器（折り畳みコンテナ）に関し、特に折り畳みコンテナを構成する側板に設けた、手指を掛けるための持ち手部（又は把持部）及びその周辺構造の改良に関するものである。 The present invention relates to a foldable article storage container (folding container), and more particularly to improvement of a handle part (or a gripping part) provided on a side plate constituting a folding container and a peripheral structure thereof. .

一般に折り畳みコンテナは、上枠、底板、及び、上枠と底板との間にあって折り畳み可能に構成された４つの側板（例えば、対向関係にある一対の折り板及び対向関係にある一対のあおり板）を備えている。そして、例えば、特許文献１の折りたたみコンテナーには、あおり板の上枠（上フレーム）寄り端部における幅方向のほぼ中央部に握り用の凹部が形成されている。この握り用凹部は、あおり板の外面（表面）に対して凹となる一方で内面（裏面）に対しては凸となるようにあおり板本体に一体成形されている。また、握り用凹部があおり板本体の内面（裏面）から突出する量は、コンテナの折り畳み時（即ちあおり板の横寝かせ時）に握り用凹部（裏面では凸部）が、上枠に装着された蓋板の閉じ動作を阻害せず且つ上枠の内側に確保された収納空間の高さ範囲内に収まるように、抑制的に設定されている。 In general, a folding container has an upper frame, a bottom plate, and four side plates that are configured to be foldable between the upper frame and the bottom plate (for example, a pair of folding plates in a facing relationship and a pair of tilting plates in a facing relationship). It has. For example, in the folding container of Patent Document 1, a gripping concave portion is formed at a substantially central portion in the width direction at the end of the upper frame (upper frame) of the tilt plate. The grip recess is formed integrally with the tilt plate main body so as to be concave with respect to the outer surface (front surface) of the tilt plate while being convex with respect to the inner surface (back surface). Also, the amount of the recess for gripping and protruding from the inner surface (back surface) of the plate body is such that when the container is folded (ie when the tilt plate is laid sideways), the grip recess (projection on the back surface) is attached to the upper frame. The cover plate is set so as not to obstruct the closing operation of the cover plate and to be within the height range of the storage space secured inside the upper frame.

実用新案登録第３００８７７２公報（全文明細書第００２７段落並びに図２，３，５及び９に示された握り用の凹部１５）Utility Model Registration No. 3008772 (Full paragraph 0027 paragraph and gripping recess 15 shown in FIGS. 2, 3, 5 and 9)

しかしながら、上記特許文献１のコンテナでは、側板本体の内面（裏面）からの突出量が抑制されているとは言え、上記握り用凹部は少なからずコンテナの内側へ突出しているため、コンテナに収納していた物品を外に引き上げるときに、握り用凹部を構成する壁部の角（例えば縦壁と横壁との直角結合部）に当該物品が引っ掛かり、コンテナ内からの物品取り出しに支障を来すことがある。 However, in the container of Patent Document 1, although the amount of protrusion from the inner surface (back surface) of the side plate main body is suppressed, the gripping recess protrudes not less than the inside of the container. When pulling out the article, the article is caught at the corner of the wall part (for example, the right-angled joint between the vertical wall and the horizontal wall) that constitutes the gripping concave part, and this hinders the removal of the article from the container. There is.

本発明はかかる事情に鑑みてなされたものであって、折り畳みコンテナのあおり板本体に凹設された持ち手部にあって、物品の出し入れに支障を生じない構造を構築することを目的とする。 The present invention has been made in view of such circumstances, and it is an object of the present invention to construct a structure that does not hinder the loading and unloading of articles in a handle portion that is recessed in the main body of a folding container. .

上記目的を達成するため、請求項１の発明は、矩形枠状の上枠、底板、及び、起立時に相対向する２枚のあおり板を少なくとも具備すると共に、各あおり板の上端部を上枠に対し回動可能に取り付け、コンテナの折り畳み時には、両あおり板を横寝かせして上枠の内側空間に収納可能とした折り畳みコンテナにおいて、前記あおり板には、その本体外面に対しては凹状にへこみ本体内面に対しては凸状に膨出する凹状持ち手部が一体成形され、この凹状持ち手部は、その奧底に相当する奧壁、該あおり板の起立時に略水平な手指の掛け代を提供する上側壁および前記上側壁に向き合うと共に上側壁に対し非平行な外下がりの傾斜壁として設けられた下側壁により区画されていることを特徴とする折り畳みコンテナである。 In order to achieve the above object, the invention of claim 1 comprises at least a rectangular frame-shaped top frame, a bottom plate, and two side plates facing each other when standing, and an upper end portion of each side plate is provided on the top frame. When the container is folded, the folding plate can be stored in the inner space of the upper frame so that both the tilting plates can be laid down sideways. A concave handle that bulges in a convex shape is integrally formed on the inner surface of the dent body, and this concave handle has a hook wall corresponding to the base of the hook and a substantially horizontal finger hook when the tilting plate stands. A folding container characterized in that it is partitioned by an upper side wall that provides a margin and a lower side wall that faces the upper side wall and that is provided as an outwardly inclined wall that is not parallel to the upper side wall.

請求項２の発明は、請求項１に記載の折り畳みコンテナにおいて、前記凹状持ち手部を構成する上側壁と奧壁との結合部は、Ｒ形状となるように湾曲形成されていることを特徴とする。 According to a second aspect of the present invention, in the folding container according to the first aspect, a joint portion between the upper side wall and the eaves wall constituting the concave handle portion is formed to be curved so as to have an R shape. And

請求項３の発明は、請求項１又は２に記載の折り畳みコンテナにおいて、前記凹状持ち手部の上側壁の前方には、あおり板本体の外面よりも更に外に突出した略水平な前方壁部が連続形成されており、その一体化した前方壁部及び上側壁により手指の掛け代が構築されることを特徴とする。 According to a third aspect of the present invention, in the folding container according to the first or second aspect, the substantially horizontal front wall portion that protrudes further outward than the outer surface of the tilt plate main body is located in front of the upper side wall of the concave handle portion. Is formed continuously, and a finger allowance is constructed by the integrated front wall and upper wall.

請求項１によれば、あおり板の起立時（即ちコンテナの組立時）、凹状持ち手部の上側壁はその内面において略水平な手指の掛け代を提供する一方、下側壁は凹状持ち手部の下端部を上側壁に対し非平行な外下がりの傾斜状に区画する。それ故、コンテナに収容していた物品を中から外に引き上げる際に当該物品が凹状持ち手部裏側の壁部に接触したとしても、下側壁の外下がり傾斜（つまり内上がり傾斜）によって物品はその引き上げが円滑化するようにガイドされ、物品が凹状持ち手部の裏側の壁部に引っ掛かる事態が回避される。それに加えて、下側壁を外下がりの傾斜壁としたことで、下側壁と奧壁との結合角度が鈍角化する。このため、各あおり板の寸法設定に起因してコンテナ折り畳み時には両あおり板をそれぞれの下端部同士を重ね合わせながら傾斜状態で横寝かせする必要がある場合でも、横寝かせ時に下端部が相対的に上、上端部が相対的に下となるように傾いたあおり板において、下側壁と奧壁との結合部位が上方に突出する量又は高さを抑制でき、その結果、横寝かせしたあおり板を収納するために必要な内側空間を提供する上枠の高さを極力低くすることが可能となり、ひいては、折り畳み時におけるコンテナの全高を極力低くすることが可能となる。 According to claim 1, when the tilting plate stands up (that is, when the container is assembled), the upper side wall of the concave handle portion provides a substantially horizontal finger allowance on the inner surface, while the lower side wall is the concave handle portion. The lower end portion of the upper and lower walls is partitioned into an outwardly inclined shape that is non-parallel to the upper side wall. Therefore, even when the article contained in the container is pulled out from the inside, even if the article comes into contact with the wall on the back side of the concave handle part, the article is The pulling up is guided so that the article is caught on the wall on the back side of the concave handle portion. In addition, since the lower side wall is an outwardly inclined wall, the coupling angle between the lower side wall and the eaves wall becomes obtuse. For this reason, even when it is necessary to lay down both sides of the two side panels in an inclined state while overlapping each other when the container is folded due to the dimension setting of each side panel, the lower ends are relatively In the tilt plate tilted so that the upper and upper end portions are relatively lower, the amount or height at which the joint portion between the lower wall and the heel wall protrudes upward can be suppressed, and as a result, It is possible to reduce the height of the upper frame that provides the inner space necessary for storage as much as possible, and as a result, it is possible to reduce the overall height of the container when folded.

請求項２によれば、凹状持ち手部を構成する上側壁と奧壁との結合部をＲ形状に湾曲形成することで、コンテナの外（上）から中（下）に物品を降ろし入れる際に、物品が当該結合部に対して引っ掛かり難くなる。従って、凹状持ち手部の裏側がコンテナ内に膨出していても、請求項１の構成との相乗効果により、コンテナに対する物品の出し入れがし易くなる。 According to claim 2, when the article is lowered from the outside (upper) to the middle (lower) of the container by forming the connecting portion between the upper side wall and the eaves wall constituting the concave handle part in a curved shape. In addition, the article is less likely to be caught with respect to the coupling portion. Therefore, even if the back side of the concave handle portion bulges into the container, the article can be easily put in and out of the container due to the synergistic effect with the structure of claim 1.

請求項３によれば、凹状持ち手部の上側壁の前方に略水平な前方壁部を連続形成し、その略水平な前方壁部と上側壁とが一体となって手指の掛け代が構築されることで、当該掛け代が十分な奥行き又は幅を持つ結果となり、手指が非常に掛け易くなる。また、あおり板本体の内面側に突出した前記上側壁と、あおり板本体の外面側に突出した前方壁部との一体的結合によって十分な奥行き又は幅を有する手指の掛け代を確保できるため、凹状持ち手部のあおり板本体内面側への膨出量と、前方壁部のあおり板本体外面側への突出量とをそれぞれ必要最小限度にとどめることができる。 According to the third aspect, a substantially horizontal front wall portion is continuously formed in front of the upper side wall of the concave handle portion, and the substantially horizontal front wall portion and the upper side wall are integrated to construct a finger allowance. As a result, the hanging allowance has a sufficient depth or width, and the fingers are very easy to hang. In addition, since the upper side wall projecting to the inner surface side of the tilt plate main body and the front wall portion projecting to the outer surface side of the tilt plate main body can be secured integrally, it is possible to secure a margin for fingers having a sufficient depth or width, The bulging amount of the concave handle portion toward the inner surface side of the tilting plate body and the protruding amount of the front wall portion toward the outer surface side of the tilting plate body can be minimized.

以下、本発明を折り畳みコンテナに適用した一実施形態を説明する。図１は、折り畳みコンテナを組み立てた状態での概略を示す。図１に示すように、コンテナは、平面矩形状且つ枠状の上枠１、その上枠１に対応する平面矩形状をなす底板２、上枠１と底板２との間で対向関係にある一対のあおり板（短側板）３、同じく対向関係にある一対の折り板（長側板）５、及び、上枠１に対し開閉可能に装着された一対の蓋９を備えている。これらコンテナ構成部材（１，２，３，５及び９）は合成樹脂等のプラスチックで作られている。なお、あおり板３の各々は、取付軸３ａによって上枠１に対し回動可能に取り付けられている。 Hereinafter, an embodiment in which the present invention is applied to a folding container will be described. FIG. 1 shows an outline in a state in which a folding container is assembled. As shown in FIG. 1, the container has a planar rectangular and frame-shaped upper frame 1, a bottom plate 2 that forms a planar rectangular shape corresponding to the upper frame 1, and the upper frame 1 and the bottom plate 2 are opposed to each other. A pair of tilt plates (short side plates) 3, a pair of folded plates (long side plates) 5 that are also opposite to each other, and a pair of lids 9 that can be opened and closed with respect to the upper frame 1 are provided. These container components (1, 2, 3, 5 and 9) are made of plastic such as synthetic resin. Each of the tilt plates 3 is rotatably attached to the upper frame 1 by an attachment shaft 3a.

（折り板について）
折り板５の各々は、上下二つの板（長側上板６及び長側下板７）を連結部８にて内側に折れ曲がり得るように連結して構成されている。長側上板６は取付軸６ａによって上枠１に対し回動可能に取り付けられ、長側下板７は取付軸７ａによって底板２に対し回動可能に取り付けられている。それ故、長側上板６及び長側下板７が一つの垂立面状態となるように各折り板５を起立させた状態で各あおり板３を垂直起立させれば、図１のようにコンテナが組み立てられる。逆に、各あおり板３を上枠１の内側に傾倒させた後、各折り板５を連結部８にて内側に折り曲げれば、コンテナが折り畳まれる。なお、折り畳み時には、上枠１の側壁下端が底板２の側壁上端に接触し、その際に上枠１と底板２との間には内部空間（即ち側板の収納空間）が確保される（図５参照）。そして、その内部空間には、折り曲げ状態の二つの折り板５、及び、その折り板５上に横寝かせ状態とされた二枚のあおり板３が収納される。 (About folded plates)
Each of the folding plates 5 is configured by connecting two upper and lower plates (the long side upper plate 6 and the long side lower plate 7) so that they can be bent inward at the connecting portion 8. The long side upper plate 6 is rotatably attached to the upper frame 1 by an attachment shaft 6a, and the long side lower plate 7 is rotatably attached to the bottom plate 2 by an attachment shaft 7a. Therefore, if each of the folding plates 5 is erected so that the long side upper plate 6 and the long side lower plate 7 are in a single vertical surface state, the respective vertical plates 3 are vertically erected as shown in FIG. A container is assembled. On the contrary, after each tilting plate 3 is tilted to the inside of the upper frame 1, if each folding plate 5 is folded inward by the connecting portion 8, the container is folded. When folded, the lower end of the side wall of the upper frame 1 contacts the upper end of the side wall of the bottom plate 2, and at that time, an internal space (that is, a storage space for the side plate) is secured between the upper frame 1 and the bottom plate 2 (see FIG. 5). In the internal space, two folded plates 5 in a folded state and two tilted plates 3 placed on the folded plate 5 are stored.

図２及び図３は折り板５を構成する長側上板６及び長側下板７の詳細を示す。長側上板６及び長側下板７はいずれも、中心分割線Ｘを挟んで左右対称の形状をなす。 2 and 3 show details of the long-side upper plate 6 and the long-side lower plate 7 constituting the folded plate 5. Each of the long side upper plate 6 and the long side lower plate 7 has a bilaterally symmetric shape with the center dividing line X in between.

図２（Ａ）に示すように、長側上板６は、比較的板薄で且つ横長な矩形状の一枚板として構成されている。長側上板６の上端部には、当該上板６を上枠１に対し回動可能に取り付けるための軸支構造６１が設けられ、長側上板６の下端部には、前記連結部８を構成するための連結構造６２が設けられている。 As shown in FIG. 2A, the long-side upper plate 6 is configured as a single plate that is relatively thin and has a horizontally long rectangular shape. The upper end of the long upper plate 6 is provided with a shaft support structure 61 for rotatably mounting the upper plate 6 with respect to the upper frame 1, and the connecting portion is provided at the lower end of the long upper plate 6. 8 is provided.

図２（Ａ）及び図３（Ａ）に示すように、長側上板６の本体外面６３（コンテナ組立時に表側となる面）には、長側上板６の上端縁から距離Ｌ（例えば１０〜１５ｍｍ）だけ下がった位置において、横方向（水平方向）に延びる持ち手リブ６４が突設されている。コンテナの組立時つまり折り板５の起立時、持ち手リブ６４は持ち手部又は把持部として機能し、その下面（腹面）に水平な手指の掛け代を提供する。持ち手リブ６４の横方向長さは例えば７０〜１００ｍｍ程度であり、持ち手リブ６４の上板本体外面６３からの突出量（又は幅）ｈは例えば５〜１５ｍｍ程度である。図４に示すように、持ち手リブ６４の突出量ｈは、上枠１及び底板２の平面寸法によって規定される組立時コンテナの平面視外形寸法を超えないように設定されている。このため、持ち手リブ６４の先端（突出端）が上枠１の側壁１１よりも外に突出することがなく、持ち手リブ６４が邪魔な突出物となることはない。 As shown in FIGS. 2A and 3A, a distance L (for example, from the upper edge of the long upper plate 6 to the main body outer surface 63 of the long upper plate 6 (the surface that becomes the front side when the container is assembled) is provided. At a position lowered by 10 to 15 mm), a handle rib 64 extending in the lateral direction (horizontal direction) is projected. When the container is assembled, that is, when the folded plate 5 is erected, the handle rib 64 functions as a handle portion or a grip portion, and provides a horizontal finger allowance on its lower surface (abdomen surface). The lateral length of the handle rib 64 is, for example, about 70 to 100 mm, and the protruding amount (or width) h of the handle rib 64 from the outer surface 63 of the upper plate body is, for example, about 5 to 15 mm. As shown in FIG. 4, the protruding amount h of the handle rib 64 is set so as not to exceed the outer dimensions in plan view of the container during assembly defined by the planar dimensions of the upper frame 1 and the bottom plate 2. For this reason, the leading end (protruding end) of the handle rib 64 does not protrude outside the side wall 11 of the upper frame 1, and the handle rib 64 does not become an obstructive protrusion.

図２（Ａ）及び図３（Ａ）に示すように、長側上板６の外面６３には、持ち手リブ６４の直上位置であって折り板５の折り畳み時に後記長側下板７の水平リブ７４と符合する位置において、複数の縦リブ６５が形成されている。これら縦方向（垂直方向）に延びる縦リブ６５の各々は、横方向に延びる持ち手リブ６４の上面（背面）につながって持ち手リブ６４と直角連結関係にあり、持ち手リブ６４の強度及び剛性をその上面側で補強している。 As shown in FIGS. 2 (A) and 3 (A), the outer surface 63 of the long upper plate 6 is positioned directly above the handle rib 64 and the long side lower plate 7 (described later) when the folded plate 5 is folded. A plurality of vertical ribs 65 are formed at positions corresponding to the horizontal ribs 74. Each of the vertical ribs 65 extending in the vertical direction (vertical direction) is connected to the upper surface (back surface) of the handle rib 64 extending in the horizontal direction and has a right-angled connection relationship with the handle rib 64. The rigidity is reinforced on the upper surface side.

図２（Ｂ）に示すように、長側下板７は、比較的板薄で且つ前記長側上板６と符合する横長な矩形状の一枚板として構成されている。長側下板７の上端部には長側上板の連結構造６２と共に前記連結部８を構成するための連結構造７１が設けられ、長側下板７の下端部には、当該下板７を底板２に対し回動可能に取り付けるための軸支構造７２が設けられている。 As shown in FIG. 2B, the long side lower plate 7 is configured as a horizontally long rectangular single plate that is relatively thin and matches the long side upper plate 6. A connecting structure 71 for configuring the connecting portion 8 together with the connecting structure 62 of the long side upper plate is provided at the upper end portion of the long side lower plate 7, and the lower plate 7 is provided at the lower end portion of the long side lower plate 7. A pivot support structure 72 is provided for pivotally attaching the base plate 2 to the bottom plate 2.

図２（Ｂ）並びに図３（Ｂ）及び（Ｃ）に示すように、長側下板７の本体外面７３には、その下端部近傍において、横方向（水平方向）に延びる受け凸部としての水平リブ７４が突設されている。この水平リブ７４は、長側下板７２の横長方向のほぼ全体にわたって延びているが、水平リブ７４の先端部には所々において略垂直方向に延びる突片状のカバー部７４ａが設けられている。 As shown in FIG. 2 (B) and FIGS. 3 (B) and 3 (C), the main body outer surface 73 of the long lower plate 7 has a receiving convex portion extending in the lateral direction (horizontal direction) in the vicinity of the lower end portion thereof. The horizontal rib 74 is projected. The horizontal rib 74 extends substantially over the entire length of the long side lower plate 72 in the laterally long direction. At the tip of the horizontal rib 74, projecting piece-like cover portions 74a extending in a substantially vertical direction are provided in some places. .

コンテナの折り畳み時には、図５に示すように、長側上板６及び長側下板７がほぼ水平になると共に長側上板の本体外面６３と長側下板の本体外面７３とが互いに向き合った状態となるように折り板５が折り畳まれる。このとき、底板２の上に寝かされた長側下板７の水平リブ７４の先端（図５では上端）に対し、連結部８にて１８０°折り返された長側上板６の縦リブ６５の先端（図５では下端）が当接する。折り畳まれた折り板５の長側上板６の上にはあおり板３が横寝かせ状態で載せられることから、あおり板３及び長側上板６の総荷重が、相互当接状態にある縦リブ６５及び水平リブ７４を介して長側下板７及び底板２に伝達される。即ち、折り畳み時におけるコンテナ内収納物（あおり板３等）に起因する垂直荷重は、縦リブ６５及び水平リブ７４によって確実に伝達及び支持される。 When the container is folded, as shown in FIG. 5, the long side upper plate 6 and the long side lower plate 7 are substantially horizontal, and the main body outer surface 63 of the long side upper plate and the main body outer surface 73 of the long side lower plate face each other. The folding plate 5 is folded so as to be in a state of being touched. At this time, the longitudinal ribs of the long upper plate 6 folded back by 180 ° at the connecting portion 8 with respect to the ends (the upper ends in FIG. 5) of the horizontal ribs 74 of the long lower plate 7 laid on the bottom plate 2. The tip of 65 (the lower end in FIG. 5) abuts. Since the tilt plate 3 is placed on the long side upper plate 6 of the folded folded plate 5 in a lying state, the total load of the tilt plate 3 and the long side upper plate 6 is in the vertical contact state in which they are in mutual contact. It is transmitted to the long side lower plate 7 and the bottom plate 2 via the rib 65 and the horizontal rib 74. That is, the vertical load caused by the contents stored in the container (the tilt plate 3 or the like) at the time of folding is reliably transmitted and supported by the vertical rib 65 and the horizontal rib 74.

なお、持ち手リブ６４の突出量ｈは、図５のように折り板５が折り畳まれたときに、持ち手リブ６４が長側下板７に干渉しないように抑制されているので、長側上板６への持ち手リブ６４の付与が、折り板５の折り畳み動作を阻害することはない。 The protrusion amount h of the handle rib 64 is suppressed so that the handle rib 64 does not interfere with the long side lower plate 7 when the folding plate 5 is folded as shown in FIG. The application of the handle rib 64 to the upper plate 6 does not hinder the folding operation of the folding plate 5.

このように本実施形態によれば、折り板５を構成する各長側板６及び７を比較的板薄に構成したにもかかわらず、折り板５の起立時に持ち手部又は把持部として機能する持ち手リブ６４を長側上板の本体外面６３に突設することで、その持ち手リブ６４に手指をかけてコンテナを持ち上げて運ぶことができる。また、折り畳み状態にある折り板５の上にあおり板３を横寝かせしたときの垂直荷重を縦リブ６５及び水平リブ７４間で確実に伝達及び支持することができ、かかる垂直荷重に起因する折り板５の変形を未然防止することができる。 As described above, according to the present embodiment, the long side plates 6 and 7 constituting the folding plate 5 are configured to be relatively thin, and function as a handle portion or a gripping portion when the folding plate 5 stands up. By projecting the handle rib 64 on the main body outer surface 63 of the long upper plate, the container can be lifted and carried by placing the finger on the handle rib 64. Further, the vertical load when the side plate 3 is laid down on the folded plate 5 in the folded state can be reliably transmitted and supported between the vertical rib 65 and the horizontal rib 74, and the folding caused by the vertical load can be performed. The deformation of the plate 5 can be prevented beforehand.

（折り板の変更例）
図６に示すように、折り板５の折り畳み時であって長側上板６の縦リブ６５と長側下板７の水平リブ７４とが当接するときに、それと協調して持ち手リブ６４の先端（図６では下端）が長側下板の本体外面７３に当接するように、当該持ち手リブ６４の突出量ｈを設定してもよい。この変更例によれば、上板の縦リブ６５及び下板の水平リブ７４間、並びに、上板の持ち手リブ６４及び下板外面７３間での協調的同時当接により、折り畳み状態にある折り板５の上に他物体（この場合、あおり板３）が載せられたときの垂直荷重を伝達及び支持する性能が更に高められる。また、図５又は図６に示す構成において、折り板５の折り畳み時に長側上板の縦リブ６５が長側下板の水平リブ７４に当接するだけでなく、長側上板の持ち手リブ６４が長側下板の水平リブ７４とも接触し得るように、持ち手リブ６４及び／又は水平リブ７４を位置設定してもよい。この場合には、持ち手リブ６４と水平リブ７４との相互接触により、例えば長側上板６が図５又は図６の水平方向にガタつくことを防止することができる。 (Example of folding plate change)
As shown in FIG. 6, when the folding plate 5 is folded and the vertical rib 65 of the long upper plate 6 and the horizontal rib 74 of the long lower plate 7 come into contact with each other, the handle ribs 64 cooperate with it. The protruding amount h of the handle rib 64 may be set so that the front end (lower end in FIG. 6) abuts the main body outer surface 73 of the long lower plate. According to this modification, the upper plate vertical rib 65 and the lower plate horizontal rib 74 and the upper plate handle rib 64 and the lower plate outer surface 73 are in a folded state due to the cooperative simultaneous contact. The performance of transmitting and supporting a vertical load when another object (in this case, the tilt plate 3) is placed on the folded plate 5 is further enhanced. Further, in the configuration shown in FIG. 5 or FIG. 6, when the folding plate 5 is folded, not only the longitudinal rib 65 of the long upper plate abuts the horizontal rib 74 of the long lower plate but also the handle rib of the long upper plate. The handle ribs 64 and / or horizontal ribs 74 may be positioned so that 64 can also contact the horizontal ribs 74 of the long lower plate. In this case, the mutual contact between the handle rib 64 and the horizontal rib 74 can prevent, for example, the long upper plate 6 from rattling in the horizontal direction of FIG. 5 or FIG.

図７及び図８は、あおり板３の詳細を示す。あおり板３の形状は中心分割線Ｙを挟んで左右対称である。図７及び図８に示すように、あおり板３は、比較的板薄で且つ正面から見て矩形状の一枚板として構成されている。特に図７（Ａ）及び（Ｂ）に示すように、あおり板本体３０の板厚は概して均一であり、上下左右の四つの端辺部から離れた本体中央部３０ａは、板厚が均一でしかも平坦な平板状となっている。あおり板３の上端部には、当該あおり板３を上枠１に対し回動可能に取り付けるための軸支構造３１が設けられている。他方、あおり板３の下端部には、コンテナの組立時に底板２の一部と係合してあおり板３の直立姿勢を確実にするための係合部３２が設けられている。 (About the tilt board)
7 and 8 show details of the tilt plate 3. The shape of the tilt plate 3 is symmetrical with respect to the center dividing line Y. As shown in FIGS. 7 and 8, the tilt plate 3 is configured as a single plate that is relatively thin and rectangular when viewed from the front. In particular, as shown in FIGS. 7A and 7B, the plate thickness of the tilt plate main body 30 is generally uniform, and the thickness of the central portion 30a of the main body 30a apart from the four upper, lower, left and right end portions is uniform. Moreover, it has a flat plate shape. A shaft support structure 31 for rotatably mounting the tilt plate 3 to the upper frame 1 is provided at the upper end of the tilt plate 3. On the other hand, the lower end portion of the tilt plate 3 is provided with an engagement portion 32 for engaging with a part of the bottom plate 2 during assembly of the container to ensure the upright posture of the tilt plate 3.

あおり板３の上端部近傍及び下端部近傍には、それぞれ横方向（水平方向）に延びる帯状膨出部３３が突出形成され、あおり板３の左右端部近傍には、縦方向（垂直方向）に延びる合計４帯の帯状膨出部３４Ａ，３４Ｂが突出形成されている。上下の横方向帯状膨出部３３及び左右の縦方向帯状膨出部３４Ａは本体中央部３０ａを四方から取り囲む。尚、図７（Ｂ）並びに図８（Ａ）及び（Ｂ）に示すように、上側の横方向帯状膨出部３３は、平板状の本体中央部３０ａと平行で且つその本体中央部３０ａよりも外側に張り出した位置にある膨出部頂面３３１と、その膨出部頂面３３１の上及び下にあって当該膨出部頂面３３１をあおり板本体３０に連結する二つの連結面３３２，３３３の合計三面で構成されている。その結果、上側の横方向帯状膨出部３３は、あおり板本体３０の表面に対しては外に張り出した凸部又は突条となる一方で、あおり板本体３０の裏面に対しては窪んだ凹部又は横溝となっている。その他の帯状膨出部（３３，３４Ａ及び３４Ｂ）についても、その基本構造は上側の横方向帯状膨出部３３と同様である。 In the vicinity of the upper end portion and the lower end portion of the tilt plate 3, strip-shaped bulging portions 33 extending in the horizontal direction (horizontal direction) are respectively formed so as to project, and in the vicinity of the left and right end portions of the tilt plate 3, the vertical direction (vertical direction) A total of four strip-shaped bulging portions 34A and 34B extending in the direction of the projection are formed. The upper and lower lateral belt-like bulging portions 33 and the left and right vertical belt-like bulging portions 34A surround the main body central portion 30a from four directions. As shown in FIGS. 7B, 8A, and 8B, the upper lateral belt-like bulged portion 33 is parallel to the flat plate-like main body central portion 30a and from the main body central portion 30a. A bulging portion top surface 331 at a position protruding outward, and two connecting surfaces 332 that are above and below the bulging portion top surface 331 and connect the bulging portion top surface 331 to the tilt plate body 30. , 333 in total. As a result, the upper lateral band-shaped bulging portion 33 becomes a convex portion or a ridge protruding outward from the surface of the tilt plate main body 30, but is depressed with respect to the back surface of the tilt plate main body 30. It is a recess or a lateral groove. The basic structure of the other belt-shaped bulging portions (33, 34A and 34B) is the same as that of the upper lateral belt-shaped bulging portion 33.

図１、図７及び図８に示すように、あおり板本体３０の幅方向中央位置であって本体上端部と前記上側の横方向帯状膨出部３３との間には、コンテナの運搬時等に手指をかける取っ手としての凹状持ち手部４０が設けられている。この凹状持ち手部４０は、その奧底に相当する奧壁４１と、その上下に位置する上側壁４２及び下側壁４３と、奧壁４１の左右に位置する左側壁４４及び右側壁４５とを有し、これら５つの壁４１〜４５によって区画されている。そして、凹状持ち手部４０は、あおり板本体３０の外面（表面）に対しては凹状にへこむ一方、本体内面（裏面）に対しては凸状に膨出するような凹凸形状であって、且つ、あおり板本体３０の内と外とを貫通させない凹凸形状として、あおり板３に対し一体成形されている。 As shown in FIG. 1, FIG. 7 and FIG. 8, at the center position in the width direction of the tilt plate main body 30 and between the upper end of the main body and the upper lateral belt-like bulged portion 33, the container is transported. A concave handle 40 is provided as a handle for placing a finger on the handle. The concave handle portion 40 includes a heel wall 41 corresponding to the bottom of the heel, an upper side wall 42 and a lower side wall 43 positioned above and below, and a left side wall 44 and a right side wall 45 positioned on the left and right sides of the heel wall 41. And defined by these five walls 41 to 45. The concave handle 40 has a concave-convex shape that dents in a concave shape with respect to the outer surface (front surface) of the tilt plate main body 30 and bulges in a convex shape with respect to the inner surface (back surface) of the main body. And it is integrally formed with respect to the tilt plate 3 as an uneven shape that does not penetrate the inside and outside of the tilt plate main body 30.

図８（Ａ）及び（Ｂ）に示すように、あおり板３の垂直起立時において、凹状持ち手部の上側壁４２はほぼ水平であるのに対し、奧壁４１は鉛直線に対し傾斜角θ１（θ１は微小な鋭角）だけ外下がり（即ち内上がり）に傾斜するように設けられている。ここで鉛直線とは、地面又は設置面に対して垂直となる仮想線を意味し、垂直起立時のあおり板本体３０は鉛直線と平行になる。また、上側壁４２と向き合う下側壁４３は、上側壁４２に対し非平行であるばかりでなく、鉛直線又はあおり板本体３０に対し傾斜角θ２（θ２はθ１よりも大きな鋭角）だけ外下がり（即ち内上がり）に傾斜する傾斜壁として設けられている。かかる奧壁４１及び下側壁４３の傾斜角設定により、奧壁４１と下側壁４３とがなす角度（結合角度）は鈍角となっている。 As shown in FIGS. 8A and 8B, when the tilting plate 3 stands upright, the upper wall 42 of the concave handle portion is substantially horizontal, while the wall 41 is inclined with respect to the vertical line. It is provided so as to be inclined outwardly (that is, upward) by θ1 (θ1 is a minute acute angle). Here, the vertical line means a virtual line perpendicular to the ground or the installation surface, and the tilt plate body 30 at the time of vertical standing is parallel to the vertical line. Further, the lower side wall 43 facing the upper side wall 42 is not only non-parallel to the upper side wall 42 but also falls outwardly by an inclination angle θ2 (θ2 is an acute angle larger than θ1) with respect to the vertical line or the tilt plate main body 30 ( That is, it is provided as an inclined wall inclined inwardly). By setting the inclination angle of the wall 41 and the lower side wall 43, the angle (coupling angle) formed between the wall 41 and the lower side wall 43 is an obtuse angle.

また、凹状持ち手部４０において、上側壁４２と奧壁４１との結合部は、角張らないようＲ形状に湾曲形成されている。更に上側壁４２の前方には、あおり板本体３０の外面よりも外（前方）に突出した略水平な前方壁部４７が連続形成されている。この前方壁部４７の前方突出量は、前記横方向帯状膨出部３３のあおり板本体３０からの突出量に相当する（図８（Ｂ）参照）。上側壁４２及び前方壁部４７は、ほぼ水平な一体化した壁部を構築し、その壁部（４２，４７）の下面は略水平な手指の掛け代を提供する。なお、縦方向に延びる前記左側壁４４及び右側壁４５は、一体化した壁部（４２，４７）の左右にそれぞれ位置して当該一体壁の強度を補強する補強リブとしての役割をも担っている。 Further, in the concave handle portion 40, the joint portion between the upper side wall 42 and the eaves wall 41 is curved and formed in an R shape so as not to be angular. Further, a substantially horizontal front wall portion 47 protruding outward (frontward) from the outer surface of the tilt plate main body 30 is continuously formed in front of the upper side wall 42. The forward protrusion amount of the front wall portion 47 corresponds to the protrusion amount of the lateral belt-like bulged portion 33 from the tilt plate body 30 (see FIG. 8B). The upper side wall 42 and the front wall portion 47 construct a substantially horizontal integrated wall portion, and the lower surfaces of the wall portions (42, 47) provide a substantially horizontal finger allowance. The left side wall 44 and the right side wall 45 extending in the vertical direction are respectively positioned on the left and right sides of the integrated wall portions (42, 47), and also serve as reinforcing ribs that reinforce the strength of the integrated wall. Yes.

本実施形態のあおり板３によれば、あおり板３の垂直起立時（即ちコンテナの組立時）に、凹状持ち手部４０の上側壁４２及びそれに連続形成された前方壁部４７とが一体となって手指の掛け代を構築するので、そこに手指を掛けてコンテナを持ち運ぶことが可能となる。また、あおり板本体３０の内面側に突出した上側壁４２と、あおり板本体３０の外面側に突出した前方壁部４７との一体的結合により十分な奥行き又は幅を有する手指の掛け代を確保できるため、手指が非常に掛け易いばかりか、凹状持ち手部４０のあおり板本体内面側への膨出量及び前方壁部４７のあおり板本体外面側への突出量をそれぞれ必要最小限度にとどめることができる。 According to the tilting plate 3 of the present embodiment, when the tilting plate 3 stands vertically (that is, when the container is assembled), the upper side wall 42 of the concave handle portion 40 and the front wall portion 47 continuously formed therewith are integrated. Since the finger allowance is constructed, it is possible to carry the container by placing the finger there. In addition, the upper wall 42 projecting toward the inner surface side of the tilt plate main body 30 and the front wall portion 47 projecting toward the outer surface side of the tilt plate main body 30 ensure a sufficient allowance for fingers having sufficient depth or width. Therefore, not only is it easy to place fingers, but also the amount of protrusion of the concave handle 40 toward the inner surface of the tilt plate main body and the amount of protrusion of the front wall 47 to the outer surface of the tilt plate main body are kept to the minimum necessary. be able to.

コンテナの組立時、凹状持ち手部４０の下側壁４３は、凹状持ち手部４０の下端部を上側壁４２に対し非平行な外下がりの傾斜状に区画する。故に、コンテナに収納していた物品を中から外に引き上げる際に当該物品が凹状持ち手部４０の裏側壁部に接触したとしても、下側壁４３の外下がり傾斜（つまり内上がり傾斜）によって当該物品は引き上げ動作が円滑化するようにガイドされ、凹状持ち手部４０の裏側壁部に引っ掛かることがない。また、凹状持ち手部４０の裏側がコンテナ内に膨出していたとしても、凹状持ち手部を構成する上側壁４２と奧壁４１との結合部をＲ形状に湾曲形成することで、コンテナの外（上）から中（下）に物品を降ろし入れる際に、当該Ｒ形状部に対して引っ掛かり難くなる。このように本実施形態によれば、起立状態にあるあおり板３の内側突部に引っ掛かることなく、物品を円滑に出し入れすることができる。 When the container is assembled, the lower side wall 43 of the concave handle portion 40 partitions the lower end portion of the concave handle portion 40 into a downwardly inclined shape that is not parallel to the upper side wall 42. Therefore, even when the article stored in the container is pulled out from the inside, even if the article comes into contact with the back side wall portion of the concave handle portion 40, the lower side wall 43 has an outer downward inclination (that is, an inner upward inclination). The article is guided so as to facilitate the lifting operation, and is not caught by the back side wall portion of the concave handle portion 40. Moreover, even if the back side of the concave handle portion 40 bulges into the container, the connecting portion of the upper wall 42 and the heel wall 41 constituting the concave handle portion is curved and formed into an R shape. When the article is dropped from the outside (top) to the inside (bottom), it becomes difficult to catch the R-shaped portion. As described above, according to the present embodiment, articles can be smoothly put in and out without being caught by the inner protrusion of the tilting plate 3 in the standing state.

本実施形態の折り畳みコンテナでは、あおり板３の全高と折り板５の横方向長さとの寸法関係に起因して、コンテナの折り畳み時には上枠１の内側空間において、図９に示すように、両あおり板３をそれぞれの下端部同士を重ね合わせながら傾斜状態で横寝かせする必要がある。特に図９に途中省略して実線で示す左側のあおり板３にあっては、その下端部を右側のあおり板３（仮想線で示す）の上に載せる格好で横寝かせするため、下端部が上端部よりも相対的に上となるような傾斜状態で横寝かせすることになる。もし仮に、あおり板３の凹状持ち手部４０を構成する下側壁４３が上側壁４２に対し平行に設けられ、且つ下側壁４３と奧壁４１とがほぼ直角に結合していたならば、下側壁４３と奧壁４１との仮定の結合部（図９に破線で示す）は、上方に大きく突出することになったであろう。この点、本実施形態のあおり板３では、奧壁４１を傾斜角θ１の外下がりな傾斜壁とし且つ下側壁４３を上側壁４２と非平行な傾斜角θ２の外下がりな傾斜壁とすることで、下側壁４３と奧壁４１との結合角度を鈍角化し、下側壁４３と奧壁４１との結合部が上方に突出する量又は高さを抑制している。従って、本実施形態によれば、横寝かせしたあおり板３を収納するために必要な内側空間を提供する上枠１の高さを、従来よりも低く設定することが可能となり、ひいては、折り畳み時におけるコンテナの全高を極力低くすることが可能となる。 In the folding container of the present embodiment, due to the dimensional relationship between the overall height of the tilt plate 3 and the lateral length of the folding plate 5, when the container is folded, as shown in FIG. It is necessary to lay the tilt plate 3 in an inclined state while overlapping the lower end portions thereof. In particular, in the case of the left side tilt plate 3 omitted in the middle of FIG. 9 and indicated by a solid line, the lower end portion is laid down on the right side tilt plate 3 (shown by a virtual line) so that the lower end portion is laid down. Lay down in an inclined state that is relatively above the upper end. If the lower side wall 43 constituting the concave handle portion 40 of the tilt plate 3 is provided in parallel to the upper side wall 42, and the lower side wall 43 and the collar wall 41 are coupled at substantially right angles, The assumed joint between the side wall 43 and the heel wall 41 (shown in broken lines in FIG. 9) would have protruded significantly upward. In this respect, in the tilt plate 3 of the present embodiment, the wall 41 is an outwardly inclined wall with an inclination angle θ1 and the lower wall 43 is an outwardly inclined wall with an inclination angle θ2 that is not parallel to the upper wall 42. Thus, the coupling angle between the lower side wall 43 and the eaves wall 41 is obtuse, and the amount or height at which the coupling portion between the lower side wall 43 and the eaves wall 41 protrudes upward is suppressed. Therefore, according to the present embodiment, it is possible to set the height of the upper frame 1 that provides the inner space necessary for storing the laying board 3 laid sideways lower than before, and as a result, when folded. It is possible to reduce the overall height of the container as much as possible.
