Description

Folded container {Folded Container}

The present invention relates to a folding container for storing and transporting various cargoes. More specifically, the door and side walls are each connected to the top plate by a wire so that when the top plate is lifted, the door and side walls unfold in sequence to store cargo. This relates to a folding container configured so that when assembled and the top is lowered, the door and side walls are folded in sequence.

In general, when exporting or importing various cargoes, they are transported stored in square box-shaped containers.

Even in the case of empty containers that do not store or transport cargo inside, these containers have the same overall volume as containers filled with cargo, so they take up the same space for storage and transport.

Therefore, when storing and transporting empty containers, not only is space utilization poor, but the costs required for storage and transport are the same as for containers filled with cargo.

To solve this problem, when the cargo is not stored or transported, the side walls of the container are separated from each other and the side walls are folded to the top of the lower plate, then the door is separated, and the separated door and top plate are placed on top of the folded side wall in order. A prefabricated container has been disclosed that reduces the volume of the container by placing it on top of the container and, if necessary, expands the top plate, door, and side walls, but secures them using fasteners of coupling pieces and locking pins to prevent them from collapsing.

The work of folding and unfolding the side walls and doors of these prefabricated containers is done manually by multiple workers or using special equipment. Manual work not only requires a large number of workers and takes a lot of time, but also folds and unfolds the container. There is a problem that workers are easily exposed to safety accidents because the work is difficult and dangerous.

In addition, special equipment can only be used in certain places where the ground is flat during folding and unfolding work, and since the middle part of the side wall is folded, its strength is weak, so additional parts for reinforcement are used, which not only increases the container's own weight. There is a problem of high manufacturing costs.
