Description

[Detailed description of the invention] This invention allows cargo to be handled while stored inside, for example, using a forklift, and can be stored by stacking multiple pieces vertically or by placing them on shelves in a multi-level warehouse. A shipping container that can be transported by truck, etc.
In detail, it consists of a rectangular underframe, a lattice-like bottom body fixed on the underframe, a lattice-like wall erected around the lattice-like bottom body, and the underframe to form a fork insertion space below the underframe. Regarding the structure and improvement of the legs in a shipping container that prevents the legs from sticking and protruding downward from the vicinity of the four corners, the purpose is to reduce the overall weight and cost by constructing the legs using plate members. The aim is to make the plate member as thin as possible and to achieve the desired load-bearing strength, even though it is constructed from a plate member.

First, embodiments of the present invention will be described below based on the drawings.

As shown in Figure 1, a shipping container has a rectangular underframe 1.
A lattice-shaped bottom body 2 fixed on this underframe 1, a lattice-shaped wall body 3 erected around this lattice-shaped bottom body 2, and fixed downward from near the four corners of the rectangular underframe 1. It is composed of four protruding legs 4.

The lattice-like wall 3 includes left and right opposing lattice-like walls 3A and 3B.
The front and rear opposing walls 3C, 3D are connected to the lattice-like bottom body 2, and the left and right opposing walls 3A, 3B are connected to the rear wall 3D. On the other hand, the front wall body 3C is divided into upper and lower halves, and these divided wall bodies 3C, 3C2 are also connected through the spiral coils 5 in a foldable manner. The left and right opposing walls 3A, 3B and the divided walls 3C1, 3C2 are releasably connected via connectors 6.

In the present invention, the leg body 4 is shown in FIGS.
As shown in the figure, it is composed of a combination of two metal plate members 4A and 4B.

That is, the first plate member 4A is bent into an L-shape or almost an L-shape when viewed from the side, and the lower plate portion 4A is used to fit the upper end of the lower container when the containers are stacked on the tip side. A U-shaped or U-shaped protrusion 4a with a downward opening is integrally formed, and the second plate member 4B is bent into a U-shape or almost a U-shape in plan view. The opposite side plate portions 4 B, 4 B,
Both end sides are welded to the vertical plate portion 4A2 of the first plate member 4A, and a reinforcing rib 4b which also serves as a mark is formed by punching outward on the intermediate connecting plate portion 4B2.

This reinforcing rib that also serves as a mark may be selected from a trademark mark of a product other than the manufacturer's trademark mark, or any other mark as required.

In this embodiment, two reinforcing vertical ribs 4C, 4C are formed by punching on the vertical plate portion 4A2 of the first plate member 4A, and the protruding portion 4a is included in the lower plate portion 4A. The two reinforcing ribs 4 d and 4 d are attached to the longitudinal rib 4 c.
, 4 c, and furthermore, two reinforcing ribs 4 e are provided at the bent corner of the free end of the protruding portion 4 a.
4 e is stamped and formed.

Further, the lower end side of the intermediate connecting plate portion 4B2 of the second plate member 4B is welded to the divided portions of the knobs 4d, 4e, . . . .

Also, the opposing side plate portions 4B, 4B of the second plate member 4B.

There are also two reinforcing vertical ribs 4f, 4f...
... is formed by stamping.

Furthermore, a notch 4g for fitting the rectangular underframe 1 into which the rectangular underframe 1 is inserted is formed over the upper end corners of the opposing side plate portions 4B1° 4B and the upper end side of the intermediate connecting plate portion 4B2.

In addition, FIG. 4 and FIG. 5 respectively show the first plate member 4A and the second plate member 4A.
This figure shows the expanded state of the plate member 4B.

The present invention provides the ribs 4 c , 4 d , 4 e , 4
This includes cases in which any or all of the ribs are not formed, but if each of these ribs is formed, the plate member 4 can be provided with the required strength while providing the leg body 4 with the required strength.
It is possible to further reduce the thickness of A and 4B.

Moreover, as shown in FIG. 6, the present invention further extends the lower sides of the opposite side plate parts 4B+, 4B+ of the second plate member 4B downward, and the shape of the lower side of this extended portion is adjusted to the lower side of the first plate member 4A. Plate part 4
A, with a shape that follows or almost follows the upper surface of the recessed part,
The legs are configured to increase the bonding strength between the drawing board members 4A and 4B by increasing the welding length of the first plate member 4A to the vertical plate portion 4A2 on both end sides of the opposite side plate portions 4B, 4B. Body 4 is also included.

The embodiments have been described above, but the gist of the leg structure of the shipping container according to the present invention is that it includes a rectangular underframe 1, a lattice-like bottom body 2 fixed on the underframe 1, and a lattice-like bottom body 2 fixed on the underframe 1. 2
In a shipping container, the legs 4 are fixedly protruded downward from the vicinity of the four corners of the rectangular frame 1, and the legs 4 are L in a side view. The first plate member 4A is bent into a U-shaped or approximately U-shaped shape and has a U-shaped or approximately U-shaped protruding portion 4a with a downward opening on the tip side of the lower plate portion 4A1. The second plate member 4B is bent into a U-shape or almost a U-shape, and both end sides of the second plate member 4B are welded to the vertical plate portion 4A2 of the first plate member 4A. The intermediate connecting plate portion 4B2 is characterized in that a reinforcing rib 4b which also serves as a mark is formed by stamping.

That is, the leg body 4 simply uses two plate members 4A and 4B, and each of these plate members 4A and 4B is simply bent into the above shape and welded to each other. As a result, cost reduction and weight reduction can be achieved from both the material and processing aspects.

And, not only this, but each of the above plate members 4A,
The above-mentioned bent shapes given to each of the drawing board members 4A and 4B are devised so that extremely high load-bearing strength can be achieved when the drawing board members 4A and 4B are welded together. , 4B can further reduce cost and weight by making the thickness of the second plate member 4B thinner, and by forming reinforcing ribs 4b on the intermediate connecting plate portion 4B2 of the second plate member 4B, the second plate member 4B can be further reduced in cost and weight. can be made even thinner while maintaining the required strength, and
Since this reinforcing rib 4b itself also serves as a mark, compared to the case where a name plate with a mark is attached separately,
This has advantages such as a reduction in mark material costs, labor savings, and a permanent display function.Therefore, even by forming such reinforcing ribs 4b, further cost reduction and weight reduction can be promoted. be.

In this way, according to the present invention, the above-mentioned effects are organically combined with each other, and the result is a considerable reduction in cost and weight, which has been strongly desired in recent years for this type of shipping container. We have now been able to provide a very effective leg structure that satisfies both of these two requirements.
