The conventional folding air cargo container has a trapezoidal overhanging portion that matches the internal shape of the aircraft fuselage, which is a feature of the container. Having various panels, all these panels are individually connected by hinges, combined, and formed into a trapezoidal shape, but in this combination, each panel bends and overlaps, making it a complicated process, When the container assembly, the number of times of folding, and the work time are taken into account, it is a cause of lower work efficiency and convenience.

Taking a commonly used monolithic LD-3 air cargo container size as an example, the maximum length is about 1.4 meters, the width is about 1.5 meters, and the height is about 1.6 meters from the ground plane. In the foldable container that has been devised in the past, in the work process of the upper lid panel, which is a part of the folding process, from the position of about 1.6 meters in height, 1.4 m × 1 The mechanism that a lid panel having a size of 5 meters square is pulled out in the horizontal state and slides diagonally down, then overlaps the side panel and folds on the floor surface is the size and weight of one lid panel. Therefore, a series of operations related to the folding with the panel supported includes a substantial load on the worker's body and a work process including a risk of injury due to panel contact during panel handling. is doing

During container assembly work, the reverse process of the folding work is followed. In any case, the structural problem that places a substantial load on the worker's body is to ensure safety. It is necessary to have multiple workers with skills, and it takes time and expense to train and educate the workers, and it is necessary to secure a certain number of workers. Such costs and additional work related to the management aspects of workers will occur.

Further, in the physical work space associated with the assembly and folding of the lid panel portion, at least the space for one lid panel is necessary, and the work cannot be performed if the certain space cannot be secured.

The present invention makes it easy to handle by reducing the number of folds and the number of times for assembly and folding, and as a result, the work efficiency can be improved and the work load can be reduced. The above-mentioned problems can be ensured by ensuring the safety of the work and making the work possible with the minimum work space, without the need for training and education of workers. Is a solution.

The purpose of the present invention is to solve the problems that have been hindered by the convenience and safety of air cargo folding containers. A possible opening / closing door is provided, and each panel constituting the container is fixed or opened by opening / closing the door, thereby simplifying the assembly and folding of the container, improving the convenience associated therewith, and high safety. A container characterized by the above is provided.

In order to take the above means, a device that enables winding and storage of the slide-type opening / closing door is provided inside the container base, and the door engages with the guide rail and allows sliding, and its tip portion Is guided directly to the position of the lower base opening / closing door discharge / injection portion or along the guide rail, and at the same time as being positioned there, it can be pulled out.

The rail and the receiving part at the two ends of the open / close door begin to engage, and the door continues to push and slide toward the rear panel via the trapezoidal panel and the guide rail of the side panel. It is closed with a door until it becomes a box shape that constitutes a container. Note that this structure in which the door is opened by lowering the door in the base direction and the box shape is released is the main structure related to assembly and folding by the slidable opening / closing door to be requested this time.

The final assembly is completed when the door that has been slid upward reaches the rear panel and is automatically locked to the rear panel, and then the assembly is completed. On the other hand, the panel is unlocked on the rear panel. Then, it can be folded by sliding it toward the lower base.

According to the present invention, the above-mentioned problems can be solved by using a trapezoidal panel, a side panel, and an openable / closable door that can slide the lid panel part, thereby eliminating the side of the trapezoid panel and the lid panel itself. The simplification that eliminates the complicated process of the trapezoidal overhanging part and the lid part makes it possible to shorten the assembly and folding time of the container and facilitate the operability related to the assembly and folding, and the work efficiency and The convenience is greatly enhanced.

By providing a slidable opening / closing door, the lid panel folding process, which was a structural problem, has the problem described in the problem (the lid panel body is pulled out and slid downward, then the side panel The mechanism that overlaps and folds on the floor surface, and in the case of assembly work, the process that is the opposite process) is completely eliminated, thereby avoiding a substantial work load on the worker's body accompanying it, In addition, it was possible to assemble and fold containers that ensure safety and do not require dedicated workers.

Also in the work space for assembling and folding the container, unlike the conventional folding container, the trapezoidal panel and the lid panel itself are eliminated from the structure. Therefore, in the assembly and folding process, the container It does not protrude from the size of itself, can be operated in the minimum necessary work space, and can be configured in any work place.
