Description

[Detailed description of the invention] This invention relates to a foldable shipping container, in particular, the top plate and floor plate are connected by a side frame that bends inward toward each other, so that it can be folded when not in use. Regarding containers.

Containers used for transporting vehicles, etc. have sufficient strength so that they can be stacked in multiple stages during transport, and
When not in use, it is necessary to be able to fold it up to reduce its volume. Therefore, the top plate and the floor plate are connected by a pair of side frames that are bent inward toward each other. Sometimes the front and rear doors can be configured to prevent folding of the extended side frame.

However, in such a side frame, the central bent part of the column for supporting the vertical load is supported by hinge A as shown in Fig. 4, and the reinforcing member B is attached to one side of the column. In such a case, as shown in Fig. 5, the reinforcing member B protrudes further inward from the central bending part of the pillar when it is bent, making it impossible to make the reinforcing member B sufficiently long. In addition to causing the problem that the reinforcing member B cannot fulfill a sufficient reinforcing role when the pillar is expanded, there is also a problem that support at the center part is insufficient when the containers are folded and stacked in multiple stages. there were.

In view of these circumstances, the present invention is a foldable transport system that does not limit the storage height of containers and ensures support at the center when containers are folded and stacked in multiple tiers. It attempts to provide a container.

An embodiment of the present invention shown in the drawings will be described below.

In FIG. 1, a container 1 includes a top plate 2, a floor plate 3, and side frames 4 connected to both sides thereof and bent inwardly.
and front and rear doors 9, and this side frame 4 has a pair of joint rods 5.
, 5 and a plurality of reinforcing members 6 connecting them.

As shown in FIG. 2, the vertical rod 5 has its upper and lower ends rotatably pivoted to brackets 7 having a U-shaped cross section fixed to the corners of the top plate 2 and the floor plate 3, respectively. It is designed to bend inward.

That is, the vertical rod 5 is formed into two parts at the center, and the vicinity of both open ends of the vertical rod 5 are rotatably connected to each other by connecting members 8 having a U-shaped cross section. Since the bracket 7 and the connecting member 8 are attached with their U-shaped openings facing oppositely to each other, the vertical rod 5 can be bent inward toward the container, but cannot be bent outward. There isn't.

Further, the left and right pair of vertical bars 5, 5 are connected to each other by reinforcing horizontal bars 6 near the upper and lower ends and near the center, so that the pair of vertical bars 5, 5 can be bent as a unit. It has become.

Furthermore, as shown in FIG.
It has a length equal to the space between the containers, and serves as a support in the center when folded containers are stacked.

Additionally, doors 9 are removably attached to the front and rear surfaces of the container by appropriate means, and when the container is in use, the doors 9 can be attached to the side frames 4, especially the vertical rods 5. They are designed to abut against each other to prevent bending.

At least one of the doors 9 may have its lower end loosely and rotatably connected to the floorboard 3, and may be folded down inside the container when not in use.

Since the present invention is constructed as described above, the connecting members 8 of both the left and right frames are stored with the upper and lower ends in contact with the top plate and the floor plate, respectively, when folded, so that the connection member 8 of the left and right frames supports the top plate and the floor plate. In addition to acting as supports and preventing their bending, the connecting members 8 are stored in close proximity when folded, so that the entire container can be made compact.
