 As shown in FIG. 1, a container according to an embodiment of the present invention has lock pins 2 rotatably supported at four corners in a container body 1 and vertically movable so as to project from a lower surface of the container body 1, and a lock pin 2 is provided. A rod-shaped lever 4 for rotating and vertically moving is provided on the lock pin 2 so as to project from the side wall of the container body 1, and an opening 5 for allowing the lever 4 to move is formed in the side wall of the container body 1.

The container body 1 is box-shaped, and has substantially rectangular insertion holes 3 for engaging with lock pins of other containers at four corners of the upper surface thereof.

As shown in FIG. 2, the lock pin 2 includes a vertical axis 10 and an engaging claw 11 fixed to the lower end of the vertical axis 10. The vertical axis 10 is inserted into a pair of circular frame-shaped upper and lower guide members 12a, 12b mounted in the container body 1 and guided vertically.

A stopper 13 is attached to the upper end of the vertical axis 10, and a spring 15 for biasing and holding the lock pin 2 upward is provided between the stopper 13 and the upper guide member 12a. It is installed. When the lock pin 2 is lifted upward by the urging force of the spring 15, the lower guide member 12b comes into contact with the engaging claw 11 to restrict the upward movement of the lock pin 2.

The engagement claw 11 has a substantially rectangular shape in plan view, which is slightly smaller than the insertion hole 3, and has a storage posture A stored in the container body 1 and an insertion of another container protruding from the lower surface of the container body 1. It can be switched between a projecting posture B which can be inserted into the hole 3. Further, the engagement claw 11 is rotatable between an engagement posture C in which it engages with the peripheral wall of the insertion hole of another container and a protrusion posture B.

As shown in FIG. 3, the lever 4 is provided so as to project in a direction orthogonal to the vertical axis 10, and is foldable downward around the pin 4a at about 90 degrees in the vicinity of the middle. As a result, between the operation posture in a straight state in which the lock pin 2 is rotated and vertically moved by protruding from the side wall of the container body 1 and the folded lever storage posture located near the side wall of the container body 1. It is possible to switch.

A pipe 20 is movably fitted on the lever 4, and a pair of protrusions (stoppers) 21 that sandwich the pipe 20 and restrict the movement of the pipe 20 are formed. By disposing the pipe 20 in the folded portion of the lever 4, the lever 4 can be held in the operating posture.

As shown in FIG. 4, the lever 4 in the lever storage posture has a length protruding from the vertical axis 10 corresponding to the distance from the vertical axis 10 to the side wall of the container body 1 and parallel to the vertical axis 10. A part of the lever 4 projects from the side wall by about half the diameter of the lever 4.

As shown in FIG. 5, the opening 5 is formed in a corner of the container body 1 and has a groove shape having a width slightly larger than the diameter of the lever 4. The opening 5 has a vertical groove portion 5a for guiding the lever 4 upward and downward, a horizontal groove portion 5b for horizontally rotating the lever 4 about the vertical axis 10 by 90 degrees, and the lever 4 is folded and stored. And a storage groove portion 5c for storing. The horizontal groove 5b communicates the lower end of the vertical groove 5a with the upper end of the storage groove 5c.

In the vertical groove portion 5 a, when the lever 4 is located at the upper end of the vertical groove portion 5, the engaging claw 11 is in the storage posture A, and when the lever 4 is located at the lower end thereof, the engaging claw 11 is in the projecting posture B. Further, when the lever 4 is located at the upper end of the vertical groove portion 5a, the lever 4 can be placed in the folded lever storage posture.

In the horizontal groove portion 5b, the attitude of the engaging claw 11 is switched while the lever 4 rotates along the horizontal groove portion 5b.

When the lever 4 is located at the upper end of the storage groove 5c, the engagement claw 11 is in the engagement posture C, and when the lever 4 is folded, the lever storage posture can be obtained.

In the above structure, when the stacked upper and lower containers are engaged and carried by the cargo handling vehicle at one time, the stacked upper and lower containers are engaged with each other. In this engagement work, the lever 4 of the uppermost container is switched from the lever storage posture to the operation posture and projected from the side wall of the container body 1 (see FIGS. 6 and 7). The pipe 20 is moved to the folded portion of the lever 4 to hold the lever 4 in the operating posture.

When the lever 4 is moved downward along the vertical groove portion 5a against the spring 13, the engaging claw 11 of the lock pin 2 is moved from the storage posture A to the protrusion posture B, and is inserted into the insertion hole 3 of the lower container. Insert (see Figure 8). When the lever 4 is rotated along the horizontal groove portion 5b, the engaging claw 11 changes from the projecting posture B to the engaging posture C, and the upper and lower containers are joined (see FIGS. 9 and 10). Set the lever 4 in the operating position to the lever storage position so that it does not get in the way when carrying.

This operation is performed also in the lower container, and all the containers to be carried at once are engaged. The spreader hanging metal fittings of the cargo handling vehicle are engaged with the insertion holes 3 of the uppermost container to carry a plurality of containers at a time. When disengaging a plurality of containers that have been transported, the above operation is reversed.

As described above, since the lock pin 2 can be rotated and moved up and down by a simple operation of the lever 4 so that the upper and lower containers can be engaged with each other, there is no need for a conventional container connecting device. , Work efficiency is improved.

Further, since the lever 4 can be housed in the opening 5, it is safe because the lever does not get in the way when carrying a container or the like.

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

For example, the lever 4 may be stretchable instead of being foldable. Moreover, the lock pin 2 may be applied to a container for steel materials.
