DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, an open container for steel material according to an embodiment of the present invention has rectangular parallelepiped corner posts 11 at four corners of a container body 10 having a rectangular shape in plan view. On the upper surface of the corner post 11, there is formed a substantially rectangular insertion hole 14 into which the hanging metal fitting 13 of the spreader 12 mounted on a cargo carrier such as a container carrier is inserted.
A vertical axis 15 is rotatably supported by a bearing 16 in the corner post 11.

The corner post 11 is, as shown in FIG.
The container body 10 projects above the steel material loading portion 10a, and its lower surface is located above the lower surface of the steel material loading portion 10a.

The hanging metal fitting 13 of the spreader 12 is a well-known one having a substantially rectangular shape in a plan view, and is oriented in a direction orthogonal to the insertion hole 14 by engaging with a peripheral wall of the insertion hole 14 of the container.
The lock posture is horizontally rotated so as to be switchable between the lock posture shown by the one-dot chain line and the unlock posture shown by the hatched portion in FIG.

At the lower end of the vertical axis 15, there is fixed an engaging body 17 which engages with the insertion hole 14 of the lower container.
The engagement body 17 has the same shape and function as the hanging metal fitting 13 of the spreader 12, and is accommodated in the step portion between the lower surface of the corner post 11 and the lower surface of the steel material loading portion 10a.

At the upper end of the vertical axis 15, the switching body 1 for switching the engaging body 17 to the locked posture or the unlocked posture.
8 is integrally formed. This switching body 18 is shown in FIG.
As described above, it is composed of two columnar projecting members 19 projecting upward from the upper end of the vertical axis 15.

As shown in FIG. 3, the projecting members 19 are diagonally opposed to each other so as to sandwich the hanging fitting 13 of the spreader 12 inserted from the insertion hole 14 or the engaging body 17 of the upper container, and the hanging fitting 13 or the upper step. When the container engagement body 17 of the above-mentioned container is rotated 90 degrees in the B direction or 90 degrees in the C direction, it is brought into contact with the hanging metal fitting 13 or the longitudinal side surface of the engagement body 17 of the upper container,
Rotate once.

When the projecting member 19 is in the unlocked position, which is the position shown by the hatched portion in FIG. 3, the engaging body 17 is in the unlocked position, and when it is in the locked position, which is the position shown by the chain line in FIG. The united body 17 is in the locked posture.

In the above structure, the container insertion hole 14
Insert the hanging metal fitting 13 of the spreader 12 into the
Rotate 3 in direction B to lock. At this time, if the engagement body 17 of the container is in the locked posture, it is in the unlocked posture, and if it is in the unlocked posture, it remains as it is. The container is lifted by the hanging metal fitting 13 and carried by the cargo handling vehicle to be stacked on another container.

When the containers thus stacked are stacked in three stages and the engagement body 17 of each container is in the unlocked posture (see FIG. 4a), the maximum number of stacked containers is To carry the upper container, first, the hanging metal fitting 13 of the spreader 12 is inserted into the insertion hole 14 of the uppermost container.

When the suspending metal fitting 13 is rotated 90 degrees in the B direction, the suspending metal fitting 13 is brought into a locked posture, and the spreader 12 and the uppermost container are engaged with each other. Then, since the protruding member 19 of the uppermost container does not rotate and the engagement body 17 of each container remains in the unlocked posture, only the uppermost container can be carried (see b in FIG. 4).

Further, when all the containers are carried at the same time, when the hanging metal fitting 13 is rotated 90 degrees in the C direction from the state of FIG. 4A, the hanging metal fitting 13 is in the lock posture and the protruding member 19 of the uppermost container is Rotate from unlocked position to locked position. Thereby, the engaging body 1 of each container
7 is in a locked position so that all three containers can be engaged and carried simultaneously (see FIG. 4c).

Furthermore, after carrying all three containers at the same time and then rotating the suspending metal 13 in the direction B by 90 degrees from the state of FIG. 4c, the suspending metal 13 is in the unlocked posture, but the protruding member 19 does not rotate. Then, only the engagement between the spreader 12 and the uppermost container is released (see d in FIG. 4).

Further, when the suspending metal fitting 13 is rotated 90 degrees in the B direction from the state of FIG. 4D, the suspending metal fitting 13 is brought into the locked posture, the spreader 12 and the uppermost container are engaged, and the uppermost container The protruding member 19 rotates from the locked position to the unlocked position. As a result, the engaging body 17 of the uppermost container is in the unlocked posture, and the protruding members 19 and the engaging bodies 17 of the remaining containers are in the same state, so that only the uppermost container can be carried (e in FIG. 4). reference).

As described above, when carrying a plurality of stacked containers by a cargo handling vehicle, the upper and lower containers can be engaged or disengaged by the rotation of the hanging metal fitting 13 of the spreader 12, so that the conventional case can be used. The work efficiency is improved as compared with the case where the upper and lower containers are manually engaged as described above.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the container is not limited to an open container for steel materials, but may be an ISO type or sealand type container.

[0026]

As is apparent from the above description, according to claims 1 and 2 of the present invention, it is possible to easily carry a plurality of stacked containers or to carry only one container, and it is possible to lift the containers. Since the upper and lower containers can be automatically engaged or disengaged by rotating the hanging metal fitting, it is not necessary to manually engage the upper and lower containers as in the conventional case, and work efficiency is improved. There is an excellent effect.
