次に、図４〜６に参照しながらこの実施の形態のツイストロック金具１の動作を説明する。   Next, the operation of the twist lock fitting 1 of this embodiment will be described with reference to FIGS.

このツイストロック金具１の第１の止め部６をコンテナの堆積体２における第１のコンテナ２１の隅金具３１の長孔３１１を介して空洞３１０に挿込みながら、第２のコンテナ２２の隅金具３２の長孔３２１を介して空洞３２０に挿入して、所定角度だけ回動すると係脱することにより、コンテナ２１とコンテナ２２を連結すると共にその連結を解除するようになされる。   While inserting the first stopper 6 of the twist lock fitting 1 into the cavity 310 through the elongated hole 311 of the corner fitting 31 of the first container 21 in the container deposit 2, the corner fitting of the second container 22 is inserted. When the container 21 is inserted into the cavity 320 through the 32 long holes 321 and is rotated by a predetermined angle, the container 21 and the container 22 are connected to each other, and the connection is released.

コンテナの堆積体２が傾斜しないとき、図３のように、揺動付勢手段８は揺動せず、揺動付勢手段８のフレーム８３内のボール８４がフレーム８３内の内面８３１の一番低いところに転がり、揺動手段７のウェイトアーム７５、７５が相対的に脱離位置に定位される。   When the container deposit 2 does not tilt, the swinging biasing means 8 does not swing as shown in FIG. 3, and the ball 84 in the frame 83 of the swinging biasing means 8 is one of the inner surfaces 831 in the frame 83. It rolls to the lowest position, and the weight arms 75, 75 of the swinging means 7 are relatively positioned at the detachment position.

図４、５に示されているように、コンテナの堆積体２が左右傾斜すると、揺動手段７や揺動付勢手段８も揺動し始める。コンテナの堆積体２が、例えば、左側に傾いていくと、揺動手段７、７、揺動付勢手段８も左側に傾くが、ボール８４が重力で左側に移動して揺動付勢手段８の他端部８２に付勢して右側の揺動手段７を推す。したがって、揺動手段７、７の他端部７２、７２が通穴５０から突き出て第２の隅金具３２内に掛止され、第２の止め部５は第２の隅金具３２から脱離することはない。   As shown in FIGS. 4 and 5, when the container deposit 2 is tilted left and right, the swinging means 7 and the swing biasing means 8 also start to swing. For example, when the container deposit 2 is tilted to the left, the swinging means 7 and 7 and the swing biasing means 8 are also tilted to the left, but the ball 84 moves to the left by gravity and swings biasing means. The right-side swinging means 7 is pushed by urging the other end portion 82 of FIG. Therefore, the other end portions 72, 72 of the swinging means 7, 7 protrude from the through hole 50 and are hooked in the second corner bracket 32, and the second stopper portion 5 is detached from the second corner bracket 32. Never do.

一方、図５、６に示されているようにコンテナの堆積体２が右側に傾いていくと、揺動手段７、７、揺動付勢手段８も右側に傾くが、ボール８４が重力で右側に移動して揺動付勢手段８の他端部８２に付勢して左側の揺動手段７を推す。したがって、揺動手段７、７の他端部７２、７２が通穴５０から突き出て第２の隅金具３２内に掛止され、第２の止め部５は第２の隅金具３２から脱離することはない。したがって、コンテナは安全に連結したままとなる。   On the other hand, as shown in FIGS. 5 and 6, when the container deposit 2 is tilted to the right, the swinging means 7 and 7 and the swing biasing means 8 are also tilted to the right. It moves to the right and urges the other end 82 of the oscillating biasing means 8 to push the left oscillating means 7. Therefore, the other end portions 72, 72 of the swinging means 7, 7 protrude from the through hole 50 and are hooked in the second corner bracket 32, and the second stopper portion 5 is detached from the second corner bracket 32. Never do. Thus, the container remains securely connected.

なお、第２の止め部５のウェブ壁５２の通穴５０側の内面５２１が向斜するように湾曲状に形成されているので、揺動手段７、７の外側面７３が軸線Ｘと鋭角をなして該内面５２１に接触することができる。したがって、揺動手段７、７は掛止位置から脱離位置へも早く回動することができる。   In addition, since the inner surface 521 on the through hole 50 side of the web wall 52 of the second stopper 5 is formed to be inclined, the outer surface 73 of the swinging means 7, 7 has an acute angle with the axis X. To contact the inner surface 521. Therefore, the rocking means 7 and 7 can be quickly rotated from the latching position to the detaching position.

なお、本発明のツイストロック金具は以上の実施の形態に限定されることなく、種々変形が可能である。例えば、揺動付勢手段８は、揺動手段７、７を共に第２の隅金具３２内に掛止する掛止手段とするとき揺動手段７、７の揺動に付勢して用いられるものであるが、揺動手段７を第２の止め部５内に掛止する効果を備えるような構成を有するならば、揺動付勢手段８を用いなくもよい。この実施の形態においては、揺動手段は、軸線Ｘを中心とする２側にそれぞれ１つ配置されているが、第２の止め部５が第２の隅金具３２から脱離しないように掛止する構成をすることができれば、揺動手段を上記構成に限ることはない。   In addition, the twist lock metal fitting of this invention is not limited to the above embodiment, A various deformation | transformation is possible. For example, the swinging biasing means 8 is used by biasing the swinging means 7, 7 when the swinging means 7, 7 are both hooking means for locking in the second corner bracket 32. However, the swing biasing means 8 may not be used as long as the swinging means 7 has an effect of hooking the swinging means 7 in the second stopper 5. In this embodiment, one oscillating means is disposed on each of the two sides about the axis X, but the second stopper 5 is hung so as not to be detached from the second corner fitting 32. The swinging means is not limited to the above configuration as long as it can be configured to stop.

本発明のツイストロック金具１によれば、貨物船が風や波のためにローリングしてコンテナの堆積体が傾斜したとき、ツイストロック金具１の第２の止め部５内に枢着された揺動手段７が揺動して他端部７２が掛止位置へ回動して第２の隅金具３２から抜けないように第２の止め部５を第２の隅金具３２内壁面を引っ掛けて挿入したままに保持することができる。したがってコンテナの堆積体２が傾斜してもしっかりと上下積層状に連結することができ、コンテナの横方向の安定性を向上することができる。   According to the twist lock metal fitting 1 of the present invention, when the cargo ship rolls due to wind or waves and the container deposit is inclined, the rocker pivotally attached in the second stopper 5 of the twist lock metal fitting 1 is supported. The second stopping portion 5 is hooked on the inner wall surface of the second corner bracket 32 so that the moving means 7 swings and the other end 72 rotates to the latching position and does not come off from the second corner bracket 32. It can be kept inserted. Therefore, even if the deposit 2 of the container is inclined, the container can be firmly connected in a vertically stacked manner, and the lateral stability of the container can be improved.

また、上記揺動付勢手段を設けたことにより、船体の傾斜に伴って揺動することにより揺動手段の作動をより有効に付勢することができる。   Further, by providing the swing urging means, the operation of the swing means can be urged more effectively by swinging with the inclination of the hull.

本発明のツイストロック金具は、コンテナの横方向の安定性の向上をするツイストロック金具に有用である。   The twist lock metal fitting of the present invention is useful for a twist lock metal fitting which improves the stability of the container in the lateral direction.
