Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a container connector for connecting, for example, a loaded container to an adjacent container.

[Conventional technology and its problems]

It has been common practice for many containers to be stacked on top of one another for shipping by ship, but simply stacking containers on top of each other poses the risk of them collapsing due to rolling or pitting of the ship's hull.
Normally, a container support surface, containers placed on it, and containers above and below are positioned, and the topmost container and the adjacent containers are connected to each other by a connecting device to prevent the containers from falling. I have to.

As a prior art example of the above-mentioned coupling device, there is one as shown in FIG. This connector has a pair of engagement blocks 2 at both ends of a threaded rod 20 formed with a reverse thread.
1 and 21 are threadedly engaged, and an L-shaped engagement pawl 22 is provided at the bottom of each engagement block 21.

By the way, the connector having the above-mentioned configuration has the engaging claw 22 in the engaging hole 30 formed in the corner of the container.
Insert the threaded rod 2 between the tops of adjacent containers.
0, the pair of engagement blocks 21 are drawn together by the rotation of the threaded rod 20, and the engagement claws 22 are engaged with the side edges of the engagement holes 30 to connect adjacent containers to each other. Adjacent containers can be prevented from moving outward, but the engaging claw 2
2 and the engagement hole 30, it is not possible to prevent the adjacent container from moving inward, and when the container moves inward, the space from the engagement hole 30 cannot be prevented. There is a risk that the engaging claw 22 will come off.

[Problem for invention]

Therefore, the technical object of this invention is to solve the above-mentioned disadvantages and to reliably prevent the inward and outward movement of adjacent containers.

[Structure of the idea]

In order to solve the above problems, this invention has a pair of columnar engagement blocks that are connected to each other so that they can be approached and separated by a turnbuckle or other puller to an engagement hole provided at the corner of the container. The engaging block is sized so that it can be inserted with a slight margin, and a protrusion is provided on the upper part of the outer periphery of each engaging block, and a retaining mechanism is provided to prevent the engaging block from coming off when it is inserted into the engaging hole. That's what I did.

[Effect]

Insert each engagement block of the connector constructed as described above into the engagement hole in the corner of an adjacent container, and operate the retaining mechanism with the protrusion in contact with the top surface of the container to remove the engagement block. When the lock is stopped and the pair of engagement blocks are pulled together by operating the puller, the opposing inner surfaces of the engagement blocks will come into contact with the inner periphery of the engagement hole, preventing outward movement of the adjacent containers. In addition, since the gap formed between the outer surface of the engagement block and the inner circumference of the engagement hole is extremely small, when the container moves inward, the inner circumference of the engagement hole will close to the engagement block. can abut the outer surface of the container and prevent outward and inward movement of adjacent containers.

〔Example〕

Embodiments of this invention will be described below with reference to FIGS. 1 to 3.

As shown in the figure, the container connector according to the invention includes a pair of engaging blocks 1, 1, a puller 10 that attracts the engaging blocks 1 to each other, and an engaging tool 10 that draws the engaging blocks 1 into the engaging hole of the container. It is comprised of a retaining mechanism A that prevents it from coming off in the inserted state.

The engagement block 1 has a columnar shape that can be inserted into an engagement hole 30 formed at a corner of the container with a slight margin, and has a protrusion on the upper part of its outer peripheral surface that can come into contact with the top surface of the container. Section 2 is provided. This protrusion 2 is connected to the engagement block 1 as shown in the figure.
It may be provided on the upper part of the opposing surface of the engagement block 1, or it may be provided on the entire outer periphery of the engagement block 1.

Further, the engagement block 1 is provided with an insertion hole 3 penetrating from the upper surface to the lower surface, and a handle 5 is formed on the upper part of the rod 4 inserted into the insertion hole 3.
An engagement plate 6 is attached to the lower end, and when the rod 4 is rotated, a part of the engagement plate 6 protrudes from the outer peripheral surface of the engagement block 1, as shown by the chain line A in FIG. Therefore, by inserting the engagement block 1 into the engagement hole provided at the corner of the container and rotating the engagement plate 6, the tip of the engagement plate 6 will engage around the engagement hole. , it is possible to prevent the engagement block 1 from coming off.

Note that the mechanism A for preventing the engagement block 1 from slipping out is not limited to the above-mentioned configuration, and any other arbitrary mechanism can be adopted.

Furthermore, a bifurcated piece 7 is formed on the upper surface of the engagement block 1, a connecting pin 8 is passed between the bifurcated pieces 7, and the end of the puller 10 is connected to this connecting pin 8.

The above-mentioned pulling tool 10 includes a pair of threaded rods 11, 11 whose ends are connected to the connecting pin 8, and the threaded rod 1
The thread formed on the threaded rod 1 has a reverse thread to the thread formed on the other threaded rod 11, and the thread formed on the threaded rod 1 of the pair
A nut 12 is threadedly engaged with 1 and 11.

In addition, the pulling tool 10 is not limited to the above-mentioned one,
For example, as shown in the prior art of FIG. 4, it may be a threaded rod with reverse threads formed at both ends. When such a puller 10 is employed, a screw hole is formed in the upper part of the engagement block 1, and the connecting portion of the engagement block to the puller is adjusted depending on the configuration of the puller to be adopted. Decide the structure accordingly. Furthermore, the pair of engagement blocks 1 and the connector 10 may be connected to each other, or may be connected detachably.

Now, insert the engagement block 1 into the engagement hole 30 formed at the top corner of the container, bring the protrusion 2 into contact with the top surface of the container, and in this state rotate the rod 4 to release a part of the engagement plate 6. By protruding outward from the outer peripheral surface of the engagement block 1, the engagement block 1 can be prevented from slipping out from the engagement hole 30.

Therefore, the engagement block 1 is inserted into each of the engagement holes of adjacent containers to prevent them from coming off, and with the pulling tool 10 positioned between the upper parts of the containers, the pulling tool 10 is operated to pair the containers. When the engaging blocks 1 are pulled together, the opposing inner surfaces of each engaging block 1 come into contact with the inner periphery of the engaging hole 30, thereby preventing adjacent containers from moving outward.

Furthermore, since the engagement block 1 is sized to fit almost snugly into the engagement hole 30, the gap formed between the outer surface of the engagement block 1 and the inner peripheral surface of the engagement hole 30 is extremely large. When the container attempts to move inward, the inner peripheral edge of the engagement hole 30 comes into contact with the outer surface of the engagement block 1, thereby preventing the container from moving inward.

〔effect〕

As described above, in this invention, the engaging block that fits into the engaging hole of the container is sized to fit almost exactly into the engaging hole, so that it engages with each of the engaging holes of adjacent containers. Insert the coupling block and operate the retaining mechanism to prevent it from coming off.
By drawing the engaging blocks together in this state, it is possible to prevent adjacent containers from moving outward and inward, and it is possible to stably hold the containers in a stacked state.

In addition, since the distance between a pair of engagement blocks that can be inserted from above into the engagement hole on the top surface of the container can be adjusted using a puller, it is not necessary to disassemble the engagement blocks when connecting adjacent containers. There are no locks, and the engagement block can be inserted into the engagement hole of each container while connected to the puller, making it possible to efficiently connect a pair of containers.

Furthermore, since the distance between the pair of engagement blocks can be adjusted, even if the distance between adjacent containers changes within the movement adjustment range of the engagement blocks, these containers can be reliably connected.
