Description

本発明は、コンテナを積み重ねる際に上下のコンテナを互いに連結するコンテナ連結具に関し、特に、荷揚の際に、コンテナを吊り上げることによって自動的に連結を外すことができるオートマチックのコンテナ連結具に関するものである。   The present invention relates to a container connector for connecting upper and lower containers to each other when stacking containers, and more particularly to an automatic container connector that can be automatically disconnected by lifting the container during unloading. is there.

船舶で多数のコンテナを輸送する際に、上下多段に積み重ねられるコンテナ同士はコンテナ連結具により連結され、船体の揺れ（ローリング、ピッチング）に対し荷崩れしないように積載される。
コンテナ連結具は、積み重ねたコンテナのコーナ金具の間に配設されるプレート状の連結座と、該連結座から突設され、上下のコーナ金具の溝穴にそれぞれコンテナ連結具の位置決めをして嵌合する上下の台座と、該台座の先端に設けられた上下のコーンとを備え、該コーンがコーナ金具の溝穴に係合することによりコンテナを連結するようにしている。 When a large number of containers are transported by a ship, containers stacked in multiple upper and lower stages are connected by a container connector, and are loaded so as not to collapse due to the shaking (rolling and pitching) of the hull.
The container connector includes a plate-shaped connecting seat disposed between the corner fittings of the stacked containers, and projects from the connecting seat, and positions the container connecting tools in the slot holes of the upper and lower corner fittings. An upper and lower pedestal to be fitted and an upper and lower cone provided at the tip of the pedestal are provided, and the containers are connected by engaging the groove of the corner metal fitting.

このようなコンテナ連結具として、上部コーンを予めコンテナ下部のコーナ金具に装着しておき、そのコンテナを下方のコンテナに積み重ねる際は、コンテナを下方のコンテナに合わせて降ろせば下部コーンが下方のコンテナのコーナ金具の溝穴に自動的に係合し、コンテナ同士の連結が行われ、反対にコンテナの陸上げの際は、コンテナを吊り上げることによって自動的に連結を外すことができるオートマチックのコンテナ連結具がある。   As such a container coupling tool, when the upper cone is attached to the corner metal fitting in the lower part of the container in advance and the container is stacked on the lower container, the lower cone is moved to the lower container if the container is lowered to the lower container. Automatic container connection that automatically engages the slot of the corner metal fittings and connects the containers to each other, and on the other hand, when the containers are landed, the containers can be automatically disconnected by lifting There are ingredients.

従来のオートマチックのコンテナ連結具としては、例えば、図１０に示すように、前記下部コーン１０が、溝穴Ｃ１の幅方向の一方に偏倚して（ここで、「偏倚」とは、図１０に示すように、溝穴Ｃ１に対して片寄って位置することをいう。）台座１１から垂下する首部１２と、該首部１２の先端からさらに偏倚方向に突出する固定突部１３とを備えている。
そして、コンテナの積付時に溝穴Ｃ１の縁部に摺接し台座１１を嵌合位置まで案内する下部傾斜面１４を、前記偏倚方向の反対側で台座１１の下部に形成するとともに、前記固定突部１３の上部に、荷揚時の引き抜き動作により溝穴Ｃ１の縁部に摺接し、コンテナ連結具を前記偏倚方向の反対側に案内することにより、固定突部１３を溝穴Ｃ１と係合しない位置まで移動させる上部傾斜面１５を形成している。
なお、図中、１６は連結座、１７は上部コーンを示している。 As a conventional automatic container connector, for example, as shown in FIG. 10, the lower cone 10 is biased to one side in the width direction of the slot C1 (here, “bias” is shown in FIG. As shown in the figure, it is positioned so as to be offset from the slot C1.) It includes a neck portion 12 that hangs down from the pedestal 11, and a fixed projection 13 that protrudes further from the tip of the neck portion 12 in the biasing direction.
A lower inclined surface 14 slidably contacting the edge of the slot C1 when the container is loaded and guiding the pedestal 11 to the fitting position is formed on the lower side of the pedestal 11 on the opposite side of the biasing direction, and the fixed protrusion The fixed protrusion 13 is not engaged with the slot C1 by slidingly contacting the edge of the slot C1 at the top of the section 13 by the pulling operation during unloading and guiding the container connector to the opposite side of the biasing direction. The upper inclined surface 15 to be moved to the position is formed.
In the figure, 16 is a coupling seat, and 17 is an upper cone.

このコンテナ連結具は、コンテナの積付時には、コーナ金具Ｃの溝穴Ｃ１に固定突部１３を挿入すると、台座１１の下部傾斜面１４が溝穴Ｃ１の縁部に摺接し、台座１１を嵌合位置まで案内することにより、固定突部１３が溝穴Ｃ１に係合する。
一方、荷揚時には、その引き抜き動作により、固定突部１３の上部傾斜面１５が溝穴Ｃ１の縁部に摺接し、コンテナ連結具を偏倚方向の反対側に案内することから、固定突部１３が溝穴Ｃ１と係合しない位置まで移動して抜き取ることができる。 In the container connector, when the container is loaded, when the fixed protrusion 13 is inserted into the slot C1 of the corner metal fitting C, the lower inclined surface 14 of the base 11 comes into sliding contact with the edge of the slot C1, and the base 11 is fitted. By guiding to the alignment position, the fixed protrusion 13 is engaged with the slot C1.
On the other hand, at the time of unloading, due to the pulling operation, the upper inclined surface 15 of the fixed protrusion 13 is in sliding contact with the edge of the slot C1, and the container connector is guided to the opposite side of the bias direction. It can be moved to a position where it does not engage with the slot C1 and extracted.

ところで、上記従来のコンテナ連結具を用いる場合、船舶に積載して輸送中に、船舶のローリングやピッチングによるコンテナの傾きにより、コンテナ連結具の係合が外れ易いという問題がある。
すなわち、図１０（ａ）に示すように、コンテナが水平に積載されていても、図１０（ｂ）に示すように、船体の揺れ（ローリングやピッチング）や風等で上方のコンテナが斜め上方に浮き上がると、図１０（ｃ）に示すように、前記固定突部１３が溝穴Ｃ１と係合しない位置まで移動することから、外側のコンテナ連結具が下方のコンテナのコーナ金具Ｃから抜けて外れようとする。 By the way, in the case of using the conventional container connector, there is a problem that the container connector is easily disengaged due to the inclination of the container due to rolling or pitching of the ship while being loaded on the ship.
That is, as shown in FIG. 10 (a), even if the containers are loaded horizontally, the upper container is tilted upward due to the hull swaying (rolling or pitching) or the wind as shown in FIG. 10 (b). 10 (c), the fixed projection 13 moves to a position where it does not engage with the slot C1, so that the outer container connector comes out of the corner metal fitting C of the lower container. Try to come off.

また、このコンテナ連結具は、固定突部１３が台座１１の中心線からかなりずれているため、固定突部１３をコーナ金具Ｃの溝穴Ｃ１に挿入しようとすると、吊り上げたコンテナを固定突部１３のずれ分だけ横に振らなければならず、隣接するコンテナとの間に一定の隙間がないと積付ができない。
そして、荷揚時には、上部傾斜面１５の案内により溝穴Ｃ１の抜け位置まで移動した固定突部１３が、溝穴Ｃ１から外れた後に、横方向の慣性が残っているため、吊り上げたコンテナが横に大きく振れることになり、隣接するコンテナに当たって傷付けるおそれがある。特に、隣接するコンテナがタンクコンテナの場合は、収容されている化学薬品等が流出する危険性もある。
さらに、左右のコンテナ連結具の一方が先にコーナ金具Ｃに入ってしまうと、もう一方のコンテナ連結具が入らず、やり直しのために再度コンテナを持ち上げると、先に入ったコンテナ連結具にこじり現象が働いて外れなくなるという問題も有している。 Further, in this container connector, since the fixed protrusion 13 is considerably deviated from the center line of the pedestal 11, when the fixed protrusion 13 is inserted into the slot C1 of the corner fitting C, the suspended container is fixed to the fixed protrusion. It must be shaken sideways by the amount of 13 deviations and cannot be loaded unless there is a certain gap between adjacent containers.
At the time of unloading, since the stationary protrusion 13 that has been moved to the position where the slot C1 is pulled out by the guide of the upper inclined surface 15 is removed from the slot C1, the lateral inertia remains, so There is a risk of hitting an adjacent container and damaging it. In particular, when the adjacent container is a tank container, there is a risk that stored chemicals and the like may flow out.
Furthermore, if one of the left and right container couplers enters the corner fitting C first, the other container coupler does not enter, and if the container is lifted again for redoing, the container coupler that has entered first will be twisted. There is also a problem that the phenomenon works and cannot be removed.

本発明は、上記従来のコンテナ連結具が有する問題点に鑑み、輸送中に容易に外れることがなく、さらに、コンテナの横振れを少なくして容易に係脱することができるオートマチックのツイスト式コンテナ連結具を提供することを目的とする。 In view of the problems of the conventional container connector, the present invention is an automatic twist type container that does not easily disengage during transportation, and that can be easily disengaged with less lateral shaking of the container. and purpose thereof is to provide a connector.

上記目的を達成するため、本発明のコンテナ連結具は、積み重ねたコンテナのコーナ金具の間に配設される連結座と、該連結座から突設され、上下のコーナ金具の溝穴にそれぞれコンテナ連結具の位置決めをして嵌合する上下の台座と、該台座から突設され、コーナ金具の溝穴に係合することによりコンテナを連結する上下のコーンとを備えたコンテナ連結具において、前記下部コーンが、下部台座から垂下する首部と、該首部の先端から溝穴の幅方向の一方側に突出する固定突部と、該固定突部の先端より基端側に先端が位置するように首部から前記固定突部の突出方向と反対方向の溝穴の幅方向に突出し、先端が溝穴内面に当接することによって、ばねの付勢力に抗して上方に揺動することにより退入する可動突部とを備え、該可動突部の上部に、荷揚時の引き抜き動作により溝穴の縁部に摺接し、コンテナ連結具を前記固定突部の突出方向に案内して、可動突部の先端を溝穴内面に当接させる傾斜面を形成するとともに、前記固定突部の上部に、前記可動突部が溝穴内面に当接した時点から溝穴の縁部に摺接し、コンテナ連結具を前記可動突部の突出方向に案内して、溝穴内面に当接した可動突部を退入させる傾斜面を形成したことを特徴とする。 In order to achieve the above object, the container connector of the present invention includes a connecting seat disposed between the corner metal fittings of the stacked containers, and a container projecting from the connecting seat, respectively in the groove holes of the upper and lower corner metal fittings. In a container connector comprising upper and lower pedestals for positioning and fitting the connector, and upper and lower cones projecting from the pedestal and connecting containers by engaging with slots in corner metal fittings, lower cone, and a neck depending from the lower portion mount, a fixed protrusion which protrudes to one side in the width direction of the slot from the front end of該首portion, so as to position the tip proximal to the distal end of the fixing protrusion portions the out collision in the width direction of the protruding direction opposite the direction of the slot of the fixed projection from the neck, by the tip comes into contact with the slot inner surface, by swinging upward against the urging force of the spring a movable protrusion which room access, the movable protrusion On the top, there is an inclined surface that slides on the edge of the slot by pulling operation when unloading, guides the container connector in the protruding direction of the fixed projection, and makes the tip of the movable projection abut the inner surface of the slot And at the top of the fixed protrusion, the movable protrusion comes into sliding contact with the edge of the slot from the time when the movable protrusion comes into contact with the inner surface of the slot, and guides the container connector in the protruding direction of the movable protrusion. In addition, an inclined surface for retracting the movable protrusion that is in contact with the inner surface of the slot is formed .

この場合において、積付時に溝穴の縁部に摺接し下部台座を嵌合位置まで案内する傾斜面を、前記固定突部の突出方向の下部台座の下部に形成することができる。 In this case, an inclined surface that slides in contact with the edge of the slot at the time of loading and guides the lower pedestal to the fitting position can be formed on the lower portion of the lower pedestal in the protruding direction of the fixed protrusion .

また、溝穴に対し斜め方向に突出する上部コーンを上部台座の先端に固定するとともに、該上部コーンの前の突出部を、溝穴への逆向き挿入時にコーナ金具の後部壁に当接して上部コーンの挿入を阻止する長さに形成することができる。   In addition, the upper cone protruding obliquely with respect to the slot is fixed to the tip of the upper pedestal, and the protrusion in front of the upper cone abuts against the rear wall of the corner metal fitting when inserted backward into the slot. It can be formed to a length that prevents insertion of the upper cone.

本発明のコンテナ連結具によれば、積付時は、下部コーンをコーナ金具の溝穴に挿入すると、可動突部が溝穴の縁部に摺接し上に押されて退入することから、コンテナをほとんど横振れさせることなく、また下部コーンを真上から溝穴に係合させることができる。
この場合、左右のコンテナ連結具の一方が先にコーナ金具に入ってしまったり、上部コーンの形状が前後逆向きの取付が可能な構造の場合に、左右のコンテナ連結具の一方を逆に取り付けてしまいコンテナ連結具を取り外すことができなくなっても、コーナ金具の他の穴から開放用治具等によって可動突部を退入させることにより、溝穴に対するクリアランスを確保し、こじり現象も生じることなくコンテナ連結具を容易に取り外すことができる。
そして、積付後、可動突部の突出方向に船の揺れが作用した場合は、斜め上方に浮き上がろうとする力に対し、下部台座と可動突部とが溝穴の縁部に係合することから、コンテナ連結具は抜けることがなく、また、固定突部の突出方向に船の揺れが作用した場合は、逆の斜め上方に浮き上がろうとする力に対し、固定突部が溝穴の反対側の縁部に係合することから、コンテナ連結具は抜けることがない。 According to the container connector of the present invention, at the time of loading, when the lower cone is inserted into the slot of the corner fitting, the movable projection is slidably contacted with the edge of the slot and retreated, The lower cone can be engaged with the slot from directly above without causing the container to almost roll.
In this case, if one of the left and right container connectors enters the corner bracket first, or if the upper cone has a structure that can be mounted in the reverse direction, attach one of the left and right container connectors in reverse. Even if it becomes impossible to remove the container connector, it is possible to secure a clearance for the slot and cause a twisting phenomenon by retracting the movable protrusion from the other hole of the corner bracket with a jig for opening. The container connector can be easily removed.
After loading, if the ship shakes in the protruding direction of the movable protrusion, the lower pedestal and the movable protrusion engage with the edge of the slot against the force of lifting upward. Therefore, the container connector does not come out, and if the ship shakes in the protruding direction of the fixed projection, the fixed projection will Since the opposite edge of the hole is engaged, the container connector does not come off.

また、荷揚時は、可動突部の上部傾斜面が荷揚時の引き抜き動作により溝穴の縁部に摺接し、コンテナ連結具を前記固定突部の突出方向に案内して、可動突部の先端を溝穴内面に当接させる一方、固定突部の上部傾斜面が、この可動突部が溝穴内面に当接した時点から溝穴の縁部に摺接し、コンテナ連結具を前記可動突部の突出方向に案内して、溝穴内面に当接した可動突部を退入させることから、コンテナをほとんど横振れさせることなく下部コーンを溝穴から真上に離脱させることができる。 Further , when unloading, the upper inclined surface of the movable protrusion is brought into sliding contact with the edge of the slot by the pulling operation during unloading, and the container coupling tool is guided in the protruding direction of the fixed protrusion, so that the tip of the movable protrusion The upper inclined surface of the fixed projection is brought into sliding contact with the edge of the slot from the time when the movable projection abuts the inner surface of the slot, and the container connector is moved to the movable projection. Since the movable protrusion that is in contact with the inner surface of the slot is retracted while being guided in the protruding direction , the lower cone can be detached from the slot directly above without causing the container to almost sway.

また、積付時に溝穴の縁部に摺接し下部台座を嵌合位置まで案内する傾斜面を、前記固定突部の突出方向の下部台座の下部に形成することにより、下部台座を溝穴の嵌合位置に確実に案内することができる。 In addition, an inclined surface that slides in contact with the edge of the slot at the time of loading and guides the lower base to the mating position is formed at the lower portion of the lower base in the protruding direction of the fixed protrusion, so that the lower base is It is possible to reliably guide to the fitting position.

また、溝穴に対し斜め方向に突出する上部コーンを上部台座の先端に固定するとともに、該上部コーンの前の突出部を、溝穴への逆向き挿入時にコーナ金具の後部壁に当接して上部コーンの挿入を阻止する長さに形成することにより、コンテナ連結具のコーナ金具への前後逆向きの取付を防止することができる。   In addition, the upper cone protruding obliquely with respect to the slot is fixed to the tip of the upper pedestal, and the protrusion in front of the upper cone abuts against the rear wall of the corner metal fitting when inserted backward into the slot. By forming the length so as to prevent the insertion of the upper cone, it is possible to prevent the container coupling tool from being attached to the corner fitting in the reverse direction.

以下、本発明のコンテナ連結具の実施の形態を、図面に基づいて説明する。   Hereinafter, embodiments of the container connector of the present invention will be described with reference to the drawings.

図１〜図４に、本発明のコンテナ連結具の第１実施例を示す。
このコンテナ連結具は、積み重ねたコンテナのコーナ金具Ｃの間に配設される連結座１と、該連結座１から突設され、上下のコーナ金具Ｃの溝穴Ｃ１にそれぞれコンテナ連結具の位置決めをして嵌合する上部台座２及び下部台座３と、該上部台座２及び下部台座３から突設され、コーナ金具Ｃの溝穴Ｃ１に係合することによりコンテナを連結する上部コーン４及び下部コーン５とを備えている。 1 to 4 show a first embodiment of a container connector of the present invention.
The container connector is positioned between the corner metal fittings C of the stacked containers, and the container connector is positioned in the slot C1 of each of the upper and lower corner metal fittings C. The upper pedestal 2 and the lower pedestal 3 that are fitted together, and the upper cone 4 and the lower pedestal 4 that project from the upper pedestal 2 and the lower pedestal 3 and connect the containers by engaging with the slot C1 of the corner metal fitting C. And a cone 5.

連結座１は、所定厚さに形成された板状の金属からなり、上下に上部台座２と下部台座３とを一体に突設している。
なお、連結座１の形状は、特に限定されるものではなく、コンテナ連結具の上下左右の位置決めができれば、例えば、上下のコーナ金具Ｃの面取り部であるＣ面にのみ挟まれるような断面三角か断面台形状の突条として形成することもできる。 The connecting seat 1 is made of a plate-like metal formed to have a predetermined thickness, and an upper base 2 and a lower base 3 are integrally protruded vertically.
The shape of the coupling seat 1 is not particularly limited. For example, if the container coupling tool can be positioned vertically and horizontally, for example, a triangular cross section that is sandwiched only by the C surface that is the chamfered portion of the upper and lower corner metal fittings C. It can also be formed as a ridge with a trapezoidal cross section.

上部台座２は、図４に示すように断面略菱形をなし、コーナ金具Ｃの溝穴Ｃ１内で左右にそれぞれ所定の範囲で回転可能に設けられるとともに、連結座１に設けた固定ピン６を溝穴Ｃ１に突出させることにより、上部コーン４が溝穴Ｃ１に係合する回転後の位置で固定することができる。
固定ピン６は、図２に示すように、ばね６１により突出方向に付勢された状態で、軸６２により連結座１に枢支されており、連結座１の下面側からレバー６３を操作することにより退入することができる。 As shown in FIG. 4, the upper pedestal 2 has a substantially diamond-shaped cross section, and is provided so as to be rotatable within a predetermined range to the left and right within the slot C <b> 1 of the corner fitting C. By projecting into the slot C1, the upper cone 4 can be fixed at the position after rotation where it engages with the slot C1.
As shown in FIG. 2, the fixing pin 6 is pivotally supported by the coupling seat 1 by the shaft 62 while being urged in the protruding direction by the spring 61, and operates the lever 63 from the lower surface side of the coupling seat 1. You can withdraw.

下部台座３は、図１又は図６（ｃ）に示すように、その上部がコーナ金具Ｃの溝穴Ｃ１に略一致して嵌合するよう形成されるとともに、その下部には、偏倚方向（ここで、「偏倚方向」とは、図６に示すように、積付時に、下部台座３から垂下する首部７が溝穴Ｃ１に対して片寄って位置方向をいう。）の反対側（後述の固定突部８の突出方向をいう。）で、積付時に溝穴Ｃ１の縁部に摺接し下部台座３を嵌合位置まで案内する傾斜面３１が形成されている。
なお、下部台座３を嵌合位置まで案内する傾斜面３１（図１１（ａ））を、図１１（ｂ）〜（ｄ）に示すような曲面からなる案内面３１Ｂ、３１Ｃ、３１Ｄで以て構成することもできる。 As shown in FIG. 1 or FIG. 6C, the lower pedestal 3 is formed so that the upper part thereof fits substantially in the slot C1 of the corner metal fitting C, and the lower part 3 has a biasing direction ( Here, as shown in FIG. 6, the “bias direction” refers to a position opposite to the neck 7 that hangs down from the lower pedestal 3 during loading ( referred to as a position direction with respect to the slot C <b> 1). refers to the projecting direction of the fixing projection 8.), the inclined surface 31 for guiding the lower pedestal 3 to the fitting position in sliding contact with the edge of the slot C1 at the time of stowage is formed.
The inclined surface 31 (FIG. 11A) for guiding the lower pedestal 3 to the fitting position is replaced by guide surfaces 31B, 31C, and 31D that are curved surfaces as shown in FIGS. 11B to 11D. It can also be configured.

上部コーン４は、図４〜図５に示すように、固定位置で溝穴Ｃ１に対し斜め方向に突出するように上部台座２の先端に固定されており、該上部コーン４の前の突出部４１は、溝穴Ｃ１への逆向き挿入時にコーナ金具Ｃの後部壁Ｃ２に当接して上部コーン４の挿入を阻止する長さに形成されている。
コーナ金具Ｃの溝穴Ｃ１は、ＩＳＯ規格によりコーナ金具Ｃの後部壁Ｃ２に近接する位置に形成されており、図５（ａ）に示すように、上部コーン４が正しい向きのときには装着できるが、図５（ｂ）に示すように、上部コーン４が前後逆向きのときには、前の突出部４１がコーナ金具Ｃの後部壁Ｃ２に当接することから、後ろの突出部４２が溝穴Ｃ１につかえて入らなくなり、これにより、コンテナ連結具のコーナ金具Ｃへの前後逆向きの取付が防止される。 As shown in FIGS. 4 to 5, the upper cone 4 is fixed to the tip of the upper pedestal 2 so as to protrude obliquely with respect to the slot C <b> 1 at the fixed position, and the protruding portion in front of the upper cone 4. 41 is formed in such a length as to abut against the rear wall C2 of the corner fitting C and prevent the insertion of the upper cone 4 during reverse insertion into the slot C1.
The slot C1 of the corner fitting C is formed at a position close to the rear wall C2 of the corner fitting C according to ISO standards, and can be mounted when the upper cone 4 is in the correct orientation as shown in FIG. As shown in FIG. 5 (b), when the upper cone 4 is reversed in the front-rear direction, the front protrusion 41 contacts the rear wall C2 of the corner metal fitting C, so that the rear protrusion 42 is formed in the slot C1. This prevents the container connector from being attached to the corner fitting C in the reverse direction.

下部コーン５は、溝穴Ｃ１の幅方向の一方に偏倚（ここで、「偏倚」とは、図６に示すように、積付時に、下部台座３から垂下する首部７が溝穴Ｃ１に対して片寄って位置することをいう。）して下部台座３から垂下する首部７と、該首部７の先端から前記偏倚方向の反対側に突出する固定突部８と、該固定突部８より基端側で首部７から前記偏倚方向に突出し、ばね９２の付勢力に抗して上方に揺動することにより退入する可動突部９とを備えている。
首部７は、下部台座３から可動突部９の突出幅を差し引いた程度に細く形成されており、下部台座３の片側から垂下している。 The lower cone 5 is biased to one side in the width direction of the slot C1 (here, “bias” means that, as shown in FIG. 6, the neck portion 7 that hangs down from the lower pedestal 3 at the time of loading is located with respect to the slot C1. The neck 7 that hangs down from the lower pedestal 3, the fixed protrusion 8 that protrudes from the tip of the neck 7 to the opposite side of the biasing direction, and the fixed protrusion 8 out collision from the neck portion 7 to the biasing direction end side, and a movable protruding portion 9 for entering and leaving by swings upward against the urging force of the spring 92.
The neck portion 7 is formed to be thin enough to subtract the protruding width of the movable protrusion 9 from the lower pedestal 3, and hangs down from one side of the lower pedestal 3.

可動突部９は、図１に示すように、その下部が首部７の先端付近に軸９１によって枢着されており、その上部がばね９２により外側に付勢されている。
可動突部９の上部には、図７（ａ）〜（ｂ）に示すように、荷揚時の引き抜き動作により溝穴Ｃ１の縁部に摺接し、コンテナ連結具を前記偏倚方向の反対側に案内して、可動突部９の先端を溝穴Ｃ１内面に当接させる傾斜面９３が形成されている。
可動突部９は下部にも傾斜面９４を備え、また、可動突部９が最も突出する位置では、首部７と合わせた幅がコーナ金具Ｃの溝穴Ｃ１の幅に近いものとなっている。
なお、可動突部９は、首部７に形成した凹部に、ばね９２により押圧された状態で嵌め込まれているため、軸９１を省略してもその位置を保持しながら揺動することが可能である。 As shown in FIG. 1, the lower portion of the movable protrusion 9 is pivotally attached to the vicinity of the tip of the neck portion 7 by a shaft 91, and the upper portion is biased outward by a spring 92.
As shown in FIGS. 7A to 7B, the upper part of the movable protrusion 9 is slidably contacted with the edge of the slot C1 by the pulling operation during unloading, and the container connector is placed on the opposite side of the biasing direction. An inclined surface 93 is formed so as to guide and abut the tip of the movable protrusion 9 against the inner surface of the slot C1.
The movable protrusion 9 is also provided with an inclined surface 94 at the bottom, and at the position where the movable protrusion 9 protrudes most, the width combined with the neck 7 is close to the width of the slot C1 of the corner fitting C. .
Since the movable projection 9 is fitted in a recess formed in the neck 7 while being pressed by a spring 92, the movable projection 9 can swing while holding its position even if the shaft 91 is omitted. is there.

固定突部８の上部には、図７（ｂ）に示すように、可動突部９が溝穴Ｃ１内面に当接した時点から溝穴Ｃ１の縁部に摺接し、コンテナ連結具を前記偏倚方向に案内して、溝穴Ｃ１内面に当接した可動突部９を退入させる傾斜面８１が形成されている。
固定突部８は、下部にも傾斜面８２を備え、また、固定突部８が最も突出する位置では、首部７と合わせた幅がコーナ金具Ｃの溝穴Ｃ１の幅に近いものとなっている。 At the top of the fixed projection 8, as shown in FIG. 7 (b), sliding contact from the time the movable protruding portion 9 is in contact with the slot C1 inner surface on the edge of the slot C1, said biasing container connector An inclined surface 81 is formed that guides in the direction and retracts the movable protrusion 9 that contacts the inner surface of the slot C1.
The fixed protrusion 8 also has an inclined surface 82 at the lower part. Further, at the position where the fixed protrusion 8 protrudes most, the width combined with the neck 7 is close to the width of the slot C1 of the corner fitting C. Yes.

次に、本実施例のコンテナ連結具の作用を説明する。
このコンテナ連結具は、図６に示すように、積付時は、下部コーン５をコーナ金具Ｃの溝穴Ｃ１に挿入すると、可動突部９が溝穴Ｃ１の縁部に摺接し上に押されて退入することから、コンテナをほとんど横振れさせることなく、また下部コーン５を溝穴Ｃ１に真上から係合させることができる。
この場合、積付時に溝穴Ｃ１の縁部に摺接し、下部台座３を嵌合位置まで案内する傾斜面３１を、前記偏倚方向の反対側で該下部台座３の下部に形成することにより、図６（ｂ）〜（ｃ）に示すように、下部台座３を溝穴Ｃ１の嵌合位置に確実に案内することができる。 Next, the operation of the container connector of this embodiment will be described.
As shown in FIG. 6, when the container connector is loaded, when the lower cone 5 is inserted into the slot C1 of the corner fitting C, the movable projection 9 is brought into sliding contact with the edge of the slot C1 and pushed upward. Then, since the container is retracted, the lower cone 5 can be engaged with the slot C1 from directly above without causing the container to swing sideways.
In this case, by forming an inclined surface 31 that slides on the edge of the slot C1 during loading and guides the lower pedestal 3 to the fitting position on the lower side of the lower pedestal 3 on the opposite side of the biasing direction, As shown in FIGS. 6B to 6C, the lower pedestal 3 can be reliably guided to the fitting position of the slot C1.

また、この積付時に、左右のコンテナ連結具の一方が先にコーナ金具Ｃに入ってしまったり、左右のコンテナ連結具の一方を逆に取り付けてしまいコンテナ連結具を取り外すことができなくなっても、例えば、図９に示すような開放用治具２０を用い、コーナ金具Ｃの他の穴に開放用治具２０の操作片２０ａを挿入し、回転操作部２０ｂの先端に回転操作部２０ｂとは自由に回転するように形成した支持部２０ｃをコーナ金具Ｃの穴の周縁に係止した状態で回転操作部２０ｂを回転操作して操作片２０ａによって可動突部９を退入させることにより、溝穴Ｃ１に対するクリアランスを確保し、こじり現象も生じることなくコンテナ連結具を容易に取り外すことができる。   Also, at the time of loading, even if one of the left and right container connectors enters the corner fitting C first, or if one of the left and right container connectors is attached in reverse and the container connector cannot be removed. For example, using an opening jig 20 as shown in FIG. 9, the operation piece 20a of the opening jig 20 is inserted into the other hole of the corner fitting C, and the rotation operation section 20b is connected to the tip of the rotation operation section 20b. In the state where the support portion 20c formed to freely rotate is locked to the peripheral edge of the hole of the corner metal fitting C, the rotary operation portion 20b is rotated and the movable protrusion 9 is retracted by the operation piece 20a. The clearance with respect to the slot C1 is ensured, and the container connector can be easily removed without causing a twisting phenomenon.

そして、積付後、図７（ａ）に示すように、前記偏倚側に船の揺れが作用した場合は、斜め上方に浮き上がろうとする力Ｐ１に対し、下部台座３と可動突部９とが溝穴Ｃ１の縁部に係合することから、コンテナ連結具は抜けることがない。
また、図７（ｂ）に示すように、前記偏倚側と反対側に船の揺れが作用した場合は、逆の斜め上方に浮き上がろうとする力Ｐ２に対し、固定突部８が溝穴Ｃ１の反対側の縁部に係合することから、コンテナ連結具は抜けることがない。 After stowage, as shown in FIG. 7 (a), if the swing of the ship on the biasing side acts, compared force P1 to be Ukiagaro obliquely upward, the lower pedestal 3 and the movable protrusion 9 Engages with the edge of the slot C1, so that the container connector does not come off.
Further, as shown in FIG. 7B, when the ship shakes on the side opposite to the bias side, the fixed protrusion 8 is a groove hole against the force P2 that tends to rise in the opposite diagonal direction. Since the opposite edge of C1 is engaged, the container connector does not come off.

また、荷揚時は、図８（ａ）〜（ｂ）に示すように、可動突部９の上部傾斜面９３が荷揚時の引き抜き動作により溝穴Ｃ１の縁部に摺接し、コンテナ連結具を前記偏倚方向の反対側に案内して、可動突部９の先端を溝穴内面に当接させる。
そして、図８（ｂ）〜（ｃ）に示すように、固定突部８の上部傾斜面８１が、この可動突部９が溝穴内面に当接した時点から溝穴Ｃ１の縁部に摺接し、コンテナ連結具を前記偏倚方向に案内して、溝穴内面に当接した可動突部９を退入させる。
最後は、図８（ｃ）に示すように、固定突部８と首部７が溝穴Ｃ１内で位置決めしながら引き抜かれることから、コンテナをほとんど横振れさせることなく下部コーン５を溝穴Ｃ１から真上に離脱させることができる。 Moreover, at the time of unloading, as shown to Fig.8 (a)-(b), the upper inclined surface 93 of the movable protrusion 9 is slidably contacted with the edge of the slot C1 by the extraction operation at the time of unloading, and a container coupling tool is attached. The tip of the movable protrusion 9 is brought into contact with the inner surface of the groove hole while being guided to the opposite side of the biasing direction.
Then, as shown in FIGS. 8B to 8C, the upper inclined surface 81 of the fixed projection 8 slides on the edge of the slot C1 from the time when the movable projection 9 contacts the inner surface of the slot. In contact with each other, the container connector is guided in the biasing direction, and the movable protrusion 9 abutting on the inner surface of the slot is retracted.
Finally, as shown in FIG. 8 (c), the fixed projection 8 and the neck 7 are pulled out while being positioned in the slot C1, so that the lower cone 5 can be removed from the slot C1 with almost no lateral shaking of the container. It can be detached right above.

また、溝穴Ｃ１に対し斜め方向に突出する上部コーン４を上部台座２の先端に固定するとともに、該上部コーン４の前の突出部４１を、溝穴Ｃ１への逆向き挿入時にコーナ金具Ｃの後部壁Ｃ２に当接して上部コーン４の挿入を阻止する長さに形成することにより、コンテナ連結具のコーナ金具Ｃへの前後逆向きの取付を防止することができる。   In addition, the upper cone 4 protruding obliquely with respect to the slot C1 is fixed to the tip of the upper pedestal 2 and the front protrusion 41 of the upper cone 4 is inserted into the slot C1 in the reverse direction when the corner fitting C is inserted. By forming the length to abut against the rear wall C2 to prevent the insertion of the upper cone 4, it is possible to prevent the container connector from being attached to the corner fitting C in the reverse direction.

次に、図１２〜図１３に、本発明のコンテナ連結具の第２実施例を説明する。

図１４〜図１７に、本発明のコンテナ連結具の第３実施例を示す。
このコンテナ連結具は、上記第１実施例のコンテナ連結具と同様の基本構造を備えている。 14 to 17 show a third embodiment of the container connector of the present invention.
This container connector has the same basic structure as the container connector of the first embodiment.

固定ピン６は、図１４に示すように、ばね６１により突出方向に付勢された状態で、軸６２により連結座１に揺動可能に枢支されており、連結座１の下側に延設した操作レバー６３を操作することにより退入する。
固定ピン６は、その先端部が軸６２の斜め上方に位置しており、この先端部が上部コーン４の挿入位置でコーナ金具Ｃの下面、すなわち溝穴Ｃ１の縁部に当接したときに押されて退入する。
そして、上部コーン４の回転後の位置では、溝穴Ｃ１の縁部から解放されて溝穴Ｃ１に入り、ばね６１により自動的に溝穴Ｃ１に突出して回り止めをなす。
また、操作レバー６３は、位置決めピン６４によって位置決めされており、コンテナ連結具を支持する手の親指で前方に押して操作し、固定ピン６を退入させるように設けられている。 As shown in FIG. 14, the fixing pin 6 is pivotally supported on the connecting seat 1 by a shaft 62 while being urged in a protruding direction by a spring 61, and extends downward from the connecting seat 1. Retreat by operating the operating lever 63 provided.
The fixed pin 6 has its tip end obliquely above the shaft 62, and when this tip end abuts the lower surface of the corner fitting C at the insertion position of the upper cone 4, that is, the edge of the slot C1. Pressed to retreat.
Then, at the position after the rotation of the upper cone 4, it is released from the edge of the slot C <b> 1 and enters the slot C <b> 1, and automatically protrudes into the slot C <b> 1 by the spring 61 to prevent rotation.
Further, the operation lever 63 is positioned by a positioning pin 64 and is provided so as to be pushed and operated by the thumb of the hand supporting the container coupling tool to retract the fixing pin 6.

次に、本実施例のコンテナ連結具の作用を説明する。
コンテナ連結具の取付は、まず吊り上げたコンテナのコーナ金具Ｃに上部コーン４を挿入することにより行う。
すなわち、上部コーン４をコーナ金具Ｃの溝穴Ｃ１に合わせて挿入するとともに、所定角度回転させることにより溝穴Ｃ１に係合させ、この回転後の位置で連結座１から溝穴Ｃ１に固定ピン６を突出させることにより、上部コーン４の回転を止め、コンテナ連結具をコーナ金具Ｃに固定する。
このとき、固定ピン６は、上部コーン４の挿入位置でコーナ金具Ｃに当接することにより退入するとともに、回転後の位置でばね６１により自動的に溝穴Ｃ１に突出して回り止めなすことから、上部コーン４を溝穴Ｃ１に挿入して回転させるだけでコーナ金具Ｃに固定することができ、これにより、上部コーン４の取付を片手で容易に行うことができる。
また、上部コーン４を取り外すときには、連結座１の下側から操作レバー６３を操作できることから、例えば、コンテナ連結具を支持する手の親指で操作レバー６３を押すことにより固定ピン６を退入させることができ、これにより、上部コーン４の取り外しを片手で容易に行うことができる。 Next, the operation of the container connector of this embodiment will be described.
The container connector is attached by first inserting the upper cone 4 into the corner metal fitting C of the suspended container.
That is, the upper cone 4 is inserted in accordance with the slot C1 of the corner fitting C, and is engaged with the slot C1 by rotating it by a predetermined angle, and the fixed pin is connected from the coupling seat 1 to the slot C1 at the position after this rotation. By projecting 6, the rotation of the upper cone 4 is stopped and the container connector is fixed to the corner fitting C.
At this time, the fixing pin 6 retreats by coming into contact with the corner metal fitting C at the insertion position of the upper cone 4 and automatically protrudes into the slot C1 by the spring 61 at the position after rotation to prevent rotation. By simply inserting the upper cone 4 into the slot C1 and rotating it, the upper cone 4 can be fixed to the corner fitting C, whereby the upper cone 4 can be easily attached with one hand.
Further, when removing the upper cone 4, the operation lever 63 can be operated from the lower side of the coupling seat 1. For example, the fixing pin 6 is retracted by pushing the operation lever 63 with the thumb of the hand supporting the container coupling tool. Thus, the upper cone 4 can be easily removed with one hand.

また、溝穴Ｃ１に対し斜め方向に突出する上部コーン４を上部台座２の先端に固定するとともに、該上部コーン４の前の突出部４１を、溝穴Ｃ１への逆向き挿入時にコーナ金具Ｃの後部壁Ｃ２に当接して上部コーン４の挿入を阻止する長さに形成することにより、コンテナ連結具のコーナ金具Ｃへの前後逆向きの取付を防止することができる。   In addition, the upper cone 4 protruding obliquely with respect to the slot C1 is fixed to the tip of the upper pedestal 2 and the front protrusion 41 of the upper cone 4 is inserted into the slot C1 in the reverse direction when the corner fitting C is inserted.
