Description

本発明は自動車部品等を収納するリターナブルケースに関する。       The present invention relates to a returnable case for storing automobile parts and the like.

自動車部品などを輸出したりする際に、効率よく積み上げるとともに部品に傷がつかないようにするため、多数回使用可能なリターナブルケースが用いられている。リターナブルケースは一般に床面を形成するスキッドと、スキッドの正面側と背面側に設けられる一対のフロントフレームと、スキッドの左右に設けられる一対のサイドフレームとから構成される。(特許文献1〜3)   When exporting automobile parts, etc., a returnable case that can be used many times is used in order to efficiently stack and prevent the parts from being damaged. The returnable case generally includes a skid that forms a floor, a pair of front frames provided on the front side and the back side of the skid, and a pair of side frames provided on the left and right sides of the skid. (Patent Documents 1 to 3)

特許文献1に開示されるリターナブルケースは、基本的に嵌め合わせによってスキッド、フロントフレーム及びサイドフレームを組み立てるものであり、特にフロントフレームとサイドフレームとの突合せコーナ部を三角形状の金具を用いて固定している。具体的には三角形状の金具に内方に突出する突部を設け、この突部をフロントフレーム及びサイドフレームに形成した受孔に係合することで固定するようにしている。また、特許文献1には一対のフロントフレームの上端部間にサポート部材(ルーフビーム)を架設して補強しているが、このサポート部材端部のフロントフレームに対する取付構造も前記同様、サポート部材に突部を設け、この突部をフロントフレームの受孔に係合するようにしている。   The returnable case disclosed in Patent Document 1 basically assembles a skid, a front frame and a side frame by fitting, and in particular, a butt corner portion of the front frame and the side frame is fixed using a triangular metal fitting. is doing. Specifically, a protrusion protruding inward is provided on a triangular metal fitting, and the protrusion is fixed by engaging with a receiving hole formed in the front frame and the side frame. Further, in Patent Document 1, a support member (roof beam) is reinforced between the upper end portions of a pair of front frames, and the mounting structure of the support member end portion with respect to the front frame is similar to the support member as described above. A protrusion is provided, and the protrusion is engaged with the receiving hole of the front frame.

特許文献2には、断面L型の固定金具をスキッド上に設け、この固定金具の内端を外側に折り返して係止部とし、この係止部によって形成される隙間に断面L型のサイドフレームの下端部の先端を入れ込んで固定する構造のリターナブルケースが開示されている。   In Patent Document 2, a fixing bracket having an L-shaped cross section is provided on a skid, an inner end of the fixing bracket is folded outward to form a locking portion, and a side frame having an L-shaped cross section is formed in a gap formed by the locking portion. A returnable case having a structure in which the tip of the lower end portion is inserted and fixed is disclosed.

また特許文献3には、ハンドル式の連結機構によってフロントフレームとサイドフレームとを結合するリターナブルケースが開示されている。   Patent Document 3 discloses a returnable case in which a front frame and a side frame are coupled by a handle type coupling mechanism.

特開平10−181741号公報Japanese Patent Laid-Open No. 10-181741 登録実用新案第3087927号公報Registered Utility Model No. 3087927 特許第3438184号公報Japanese Patent No. 3438184

特許文献1にあっては、固定金具やサポート部材に設けた小さな突部を相手部材の受孔に係合させる構造であり、正確に突部と受孔の位置を一致させる必要がある。しかしながらこれらを正確な位置に設けることは難しく、仮に位置が正確でも他の部材との関係で位置がズレてしまうことがある。このため組付け後の各部材がガタつくことになる。   Patent Document 1 has a structure in which a small protrusion provided on a fixing metal fitting or a support member is engaged with a receiving hole of a mating member, and the positions of the protruding part and the receiving hole need to be exactly matched. However, it is difficult to provide these at an accurate position, and even if the position is accurate, the position may be shifted due to the relationship with other members. For this reason, each member after assembling becomes loose.

特許文献2にあっては、係止部によって形成される隙間に比較してサイドフレームの下端部の厚さが薄いため、サイドフレームを押さえつけることができず、特許文献1と同様にガタつくことになる。   In Patent Document 2, since the thickness of the lower end portion of the side frame is thinner than the gap formed by the locking portion, the side frame cannot be pressed down and is rattling as in Patent Document 1. become.

特許文献3に開示されるハンドル式の連結機構は、コーナ部においてフロントフレームとサイドフレームとを確実に連結することができるが、全ての連結箇所にハンドル式の連結機構を設けたのでは、組立て及び分解に時間がかかり、またガタつきも生じやすい。   The handle type connection mechanism disclosed in Patent Document 3 can reliably connect the front frame and the side frame at the corner portion. However, if the handle type connection mechanism is provided at all the connection points, the assembly is possible. In addition, it takes time to disassemble and is prone to rattle.

上記課題を解決すべく本発明は、リターナブルケースを構成する一対のフロントフレームの上メンバ間にルーフビームが着脱自在とされ、このルーフビームは両端部にフロントフレームの上メンバを抱持する連結部を備え、この連結部は前記上メンバに上方から係合すべく下方が開放された係合部と、この係合部の外側に回動自在に設けられた支持プレートからなり、この支持プレートはバネによって前記係合部に入り込んだ上メンバの下面に当接する方向に付勢され、前記係合部の下方に開放された開口内に前記上メンバの上端が入り込んだ状態から前記ルーフビームを下げることで前記係合部内に前記上メンバが嵌合する構成とした。 In order to solve the above-described problems, the present invention provides a roof beam that is detachable between a pair of front members constituting a returnable case, and the roof beam is a connecting portion that holds the upper member of the front frame at both ends. The connecting portion includes an engaging portion whose lower portion is opened so as to be engaged with the upper member from above, and a support plate rotatably provided outside the engaging portion. The roof beam is lowered from the state in which the upper end of the upper member enters the opening opened below the engaging portion, which is biased in a direction to contact the lower surface of the upper member that has entered the engaging portion by a spring. It was the upper member fitting match that configured in the engaging portion by.

発明によれば、リターナブルケース全体の補強とガタつき防止をワンタッチで行うことができる。また、一旦嵌合した連結部はスプリングの弾発力で支持プレートが上メンバの下面押し当てられるので容易に外れることはない。特に、連結部を構成する支持プレートに、フロントフレームまたはサイドフレームの縦メンバと係合する凹部を形成することで位置決めが容易になる。 According to the present invention, it is possible to reinforce the entire returnable case and prevent rattling with one touch. Further, the connecting portion once fitted does not easily come off because the support plate is pressed against the lower surface of the upper member by the spring force of the spring. In particular, positioning is facilitated by forming a recess that engages with the vertical member of the front frame or side frame in the support plate constituting the connecting portion.

以下に本発明の実施の形態を添付図面に基づいて説明する。図1は本発明に係るリターナブルケースの全体斜視図であり、リターナブルケースは床面を形成するスキッド1と、このスキッド1の正面側と背面側に設けられる一対のフロントフレーム2,2と、スキッド1の左右に設けられる一対のサイドフレーム3,3と、一対のフロントフレーム2,2の上メンバ間に架設されるルーフビーム4から構成される。   Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an overall perspective view of a returnable case according to the present invention. The returnable case includes a skid 1 forming a floor surface, a pair of front frames 2 and 2 provided on the front side and the back side of the skid 1, and a skid. 1 includes a pair of side frames 3, 3 provided on the left and right sides of the frame 1, and a roof beam 4 installed between upper members of the pair of front frames 2, 2.

スキッド1は、平面図である図2、正面図である図3、図2のa部拡大図である図4及び図2のb−b方向矢視図である図5に示すように、角パイプからなる横メンバ10と前後メンバ11とを格子状に組付け、その上に床パネル12を載置している。   As shown in FIG. 2 which is a plan view, FIG. 3 which is a front view, FIG. 4 which is an enlarged view of a part of FIG. 2 and FIG. 5 which is a view taken along the line bb in FIG. A horizontal member 10 made of pipes and front and rear members 11 are assembled in a lattice shape, and a floor panel 12 is placed thereon.

外枠部分を構成する横メンバ10と前後メンバ11との突合せ部は図4に示すようにコーナ金具13にて固定され、また外枠部分を構成する横メンバ10の略中央部の前面側と背面側に、図5に示すように係合プレート14,15を取付け、これら係合プレート14,15間に上方からフロントフレーム2の下メンバ20を差し込むことで、スキッド1上にフロントフレーム2が固定される。
尚、実施例にあっては係合プレート14,15の高さ位置をずらすことで下メンバ20を挿入しやすくしている。
As shown in FIG. 4, the abutting portion between the lateral member 10 and the front and rear members 11 constituting the outer frame portion is fixed by a corner fitting 13, and the front side of the substantially central portion of the lateral member 10 constituting the outer frame portion. As shown in FIG. 5, the engagement plates 14 and 15 are attached to the back side, and the lower member 20 of the front frame 2 is inserted between the engagement plates 14 and 15 from above so that the front frame 2 is mounted on the skid 1. Fixed.
In the embodiment, the lower member 20 can be easily inserted by shifting the height positions of the engagement plates 14 and 15.

また、外枠部分を構成する前後メンバ11の中央部には位置決めプレート16を設け、両端部近傍にはサイドフレーム3を固定する固定金具17を取付けている。   Further, a positioning plate 16 is provided at the center of the front and rear members 11 constituting the outer frame portion, and a fixing bracket 17 for fixing the side frame 3 is attached in the vicinity of both ends.

前記フロントフレーム2は図1に示すように、下メンバ20、上メンバ21、4本の縦メンバ22および3本の斜めメンバ23から構成されている。   As shown in FIG. 1, the front frame 2 includes a lower member 20, an upper member 21, four vertical members 22, and three oblique members 23.

前記サイドフレーム3は図6に示すように、下メンバ30、上メンバ31、3本の縦メンバ32および2本の斜めメンバ33から構成され、下メンバ30については断面L字状のアングル材を用い、上メンバ31と縦メンバ32とのコーナ部にはフロントフレーム2と連結するためのハンドル式連結機構34を設けている。   As shown in FIG. 6, the side frame 3 is composed of a lower member 30, an upper member 31, three vertical members 32, and two oblique members 33, and the lower member 30 is made of an angle material having an L-shaped cross section. In use, a handle type coupling mechanism 34 for coupling to the front frame 2 is provided at a corner portion of the upper member 31 and the vertical member 32.

ここで、前記スキッド1上に設けた固定金具17は図7に示すように、垂直部17aの下端から外側に延びる水平部17b、水平部17bから内側に斜めに折り返された係止片17cからなり、サイドフレーム3を固定金具17に固定するには、先ず図7(a)に示すように、サイドフレーム3を外側に倒し、アングル材からなる下メンバ30の先端部を固定金具17内に挿入し、次いで図の矢印に示すようにアングル材のコーナ部を固定金具17内面に当てつつサイドフレーム3を垂直状態になるように回動せしめる。すると図7(b)に示すように、下メンバ30(アングル材)の先端部が固定金具17の係止片17cの裏側面に当たり、サイドフレーム3の下メンバ30は固定金具17の内面に押し付けられて固定される。   Here, as shown in FIG. 7, the fixing bracket 17 provided on the skid 1 includes a horizontal portion 17b extending outward from the lower end of the vertical portion 17a, and a locking piece 17c obliquely folded inward from the horizontal portion 17b. Thus, in order to fix the side frame 3 to the fixing bracket 17, first, as shown in FIG. 7A, the side frame 3 is tilted outward, and the tip of the lower member 30 made of an angle member is placed in the fixing bracket 17. Then, as shown by the arrows in the figure, the side frame 3 is rotated so as to be in a vertical state while the corner portion of the angle member is applied to the inner surface of the fixing bracket 17. Then, as shown in FIG. 7B, the tip of the lower member 30 (angle member) hits the back side surface of the locking piece 17 c of the fixing bracket 17, and the lower member 30 of the side frame 3 presses against the inner surface of the fixing bracket 17. Fixed.

また前記ハンドル式連結機構34は図8,9に示すように、サイドフレーム3の上メンバ31の下面にブラケット35を固着し、このブラケット35にシャフト36を摺動自在に取り付け、このシャフト36にはハンドル37を設けるとともにシャフト36の先端部36aは、図8のa−a方向から見た図10(a)に示すように、ハンドル37の取り付け方向と60°位相をずらせて折り曲げている。ここで、シャフト36が縦メンバ22と係合したロック状態では、シャフト36はブラケット35の端部から突出し、大きな荷重がかかるとシャフト36が曲がるおそれがあるので、上メンバ31の下面に角パイプ31aを固着し突出したシャフト36が曲がるのを防止している。   As shown in FIGS. 8 and 9, the handle type connecting mechanism 34 has a bracket 35 fixed to the lower surface of the upper member 31 of the side frame 3, and a shaft 36 is slidably attached to the bracket 35. As shown in FIG. 10A as viewed from the direction aa in FIG. 8, the handle 36 is provided and the tip 36a of the shaft 36 is bent with a 60 ° phase shift from the direction in which the handle 37 is attached. Here, in the locked state in which the shaft 36 is engaged with the vertical member 22, the shaft 36 protrudes from the end portion of the bracket 35, and if a large load is applied, the shaft 36 may be bent. 31a is fixed and the protruding shaft 36 is prevented from bending.

また、前記ブラケット35には矩形状の係止部38と円形のストッパラバー39を取り付け、図8に示すようにフロントフレーム2の縦メンバ22との係合が解除された状態では、シャフト36は後退し、ハンドル37は係止部38とストッパラバー39との間に入り込んでいる。   In addition, a rectangular locking portion 38 and a circular stopper rubber 39 are attached to the bracket 35, and when the engagement with the vertical member 22 of the front frame 2 is released as shown in FIG. The handle 37 is retracted, and the handle 37 enters between the locking portion 38 and the stopper rubber 39.

一方、フロントフレーム2の縦メンバ22と係合するには、図8及び図10(a)に示す状態からハンドル37を手前に約30°引いてハンドル37を係止部38とストッパラバー39との間から外す。このときシャフト36の先端部36aは、図10(a)に示すように、角パイプ31aの下面に当接し、これ以上ハンドル37を手前に廻すことができなくなる。   On the other hand, in order to engage with the vertical member 22 of the front frame 2, the handle 37 is pulled about 30 ° toward the front from the state shown in FIGS. Remove from between. At this time, as shown in FIG. 10A, the distal end portion 36a of the shaft 36 abuts against the lower surface of the square pipe 31a, and the handle 37 can no longer be rotated forward.

そして、そのままシャフト36を図において右側に移動すると、図10(b)に示すように、シャフト36の先端部36aがフロントフレーム2の縦メンバ22に形成した長孔22aの外縁に当たり、それ以上シャフト36を移動できなくなる。更に、この状態からハンドル37を約90°(合計120°)廻すと、図10(c)に示すように、シャフト36の先端部36aと長孔22aとが一致するので、長孔22aに先端部36aを貫通させ、この後ハンドル37を下に回し(約120°)、ストッパラバー39と縦メンバ22との間に入れ込むとシャフト36の先端部36aは長孔22aに係合し、フロントフレーム2とサイドフレーム3が連結される。   Then, when the shaft 36 is moved rightward in the figure, the tip 36a of the shaft 36 hits the outer edge of the long hole 22a formed in the vertical member 22 of the front frame 2 as shown in FIG. 36 cannot be moved. Further, when the handle 37 is turned about 90 ° (120 ° in total) from this state, as shown in FIG. 10C, the tip portion 36a of the shaft 36 and the long hole 22a coincide with each other. When the handle 37 is turned downward (about 120 °) and inserted between the stopper rubber 39 and the vertical member 22, the tip 36a of the shaft 36 engages with the elongated hole 22a, The frame 2 and the side frame 3 are connected.

前記したように、本発明のリターナブルケースは一対のフロントフレーム2の上メンバ21,21間にルーフビーム4,4を架設して補強している。このルーフビーム4の構造を図11〜図16に基づいて説明する。尚、図11はルーフビームの平面図、図12はルーフビームの側面図、図13は図12のc方向矢視図、図14は図12のd方向矢視図、図15は図12のe方向矢視図、図16(a)〜(d)はルーフビームをフロントフレームに取り付ける手順を説明した図である。   As described above, the returnable case of the present invention reinforces the roof beams 4 and 4 between the upper members 21 and 21 of the pair of front frames 2. The structure of the roof beam 4 will be described with reference to FIGS. 11 is a plan view of the roof beam, FIG. 12 is a side view of the roof beam, FIG. 13 is a view in the direction c of FIG. 12, FIG. 14 is a view in the direction d of FIG. FIGS. 16A to 16D are views illustrating a procedure for attaching the roof beam to the front frame.

ルーフビーム4は両端部にフロントフレーム2の上メンバ21を抱持する連結部40を備えている。この連結部40は前記上メンバ21に上方から係合すべく下方が開放された係合部41と、この係合部の外側に回動自在に設けられた支持プレート42からなる。   The roof beam 4 includes connecting portions 40 that hold the upper member 21 of the front frame 2 at both ends. The connecting part 40 includes an engaging part 41 whose lower part is opened so as to be engaged with the upper member 21 from above, and a support plate 42 that is rotatably provided outside the engaging part.

係合部41は前後の垂直片41a、41bを水平部41c、41cで連結し、水平部41c、41c間は開口とし、前方の垂直片41aを後方の垂直片41bよりも短く設定している。   The engaging portion 41 connects the front and rear vertical pieces 41a and 41b with the horizontal portions 41c and 41c, the horizontal portions 41c and 41c are opened, and the front vertical piece 41a is set shorter than the rear vertical piece 41b. .

また、後方の垂直片41bの裏側には軸43が設けられ、この軸43に前記支持プレート42がスプリング43によって係合部41の下方に開放された開口を塞ぐ方向に付勢されて取り付けられている。但し垂直片41bがストッパとして作用するので支持プレート42は前記水平部41cと略平行な位置までしか閉じない。更に、支持プレート42の中央部にはフロントフレーム2の縦メンバ22との間に空間を形成する凹部45が形成されている。 Also, a shaft 43 is provided on the back side of the rear vertical piece 41b, and the support plate 42 is urged and attached to the shaft 43 by a spring 43 in a direction to close the opening opened below the engaging portion 41. ing. However, since the vertical piece 41b acts as a stopper, the support plate 42 is closed only to a position substantially parallel to the horizontal portion 41c. Further, a concave portion 45 that forms a space with the vertical member 22 of the front frame 2 is formed at the center of the support plate 42.

以上のルーフビーム4は1人で簡単にフロントフレーム2の上メンバ21、21間に架け渡すことができる。
即ち、先ず、作業者から離れた側の連結部40の支持プレート42の凹部45をフロントフレーム2の縦メンバ22に係合せしめて位置決めした後、図16(a)に示すように、作業者から離れた側の連結部40をフロントフレーム2の上メンバ21に斜め上方から押し当てる。この状態から矢印で示すようにルーフビーム4を前方(図16(a)において左方)に押し出す。
The above roof beam 4 can be easily bridged between the upper members 21 and 21 of the front frame 2 by one person.
That is, first, after positioning the recess 45 of the support plate 42 of the connecting portion 40 on the side away from the operator by engaging with the vertical member 22 of the front frame 2, as shown in FIG. The remote connecting portion 40 is pressed against the upper member 21 of the front frame 2 obliquely from above. From this state, the roof beam 4 is pushed forward (leftward in FIG. 16A) as indicated by an arrow.

すると、図16(b)に示すように、支持プレート42が上メンバ21自身によってスプリング43に抗して開となり、上メンバ21の上端が係合部41の下方に開放された開口内に入り込む。この状態からルーフビーム4を矢印に示すように下げることで係合部41内に上メンバ21に嵌合する。また、一旦嵌合した連結部40はスプリング43の弾発力で支持プレート42が上メンバ21の下面押し当てられるので容易に外れることはない。   Then, as shown in FIG. 16B, the support plate 42 is opened against the spring 43 by the upper member 21 itself, and the upper end of the upper member 21 enters into the opening opened below the engaging portion 41. . From this state, the roof beam 4 is lowered as indicated by an arrow so that the upper member 21 is fitted into the engaging portion 41. Further, the connecting portion 40 once fitted is not easily detached because the support plate 42 is pressed against the lower surface of the upper member 21 by the elastic force of the spring 43.

この後、作業者の手元側の連結部40については、位置決めをした後、作業者の手で支持プレート42をスプリング43に抗して開方向に回動させ、上メンバ21の上から係合部41を嵌合させ、次いで支持プレート42をスプリング43の弾発力で回動させ上メンバ21を包持する。この状態を図16(c)および下面図である図16(d)に示している。   Then, after positioning the connecting portion 40 on the operator's hand side, the support plate 42 is rotated in the opening direction against the spring 43 by the operator's hand, and is engaged from above the upper member 21. The portion 41 is fitted, and then the support plate 42 is rotated by the elastic force of the spring 43 to hold the upper member 21. This state is shown in FIG. 16C and FIG. 16D which is a bottom view.
