1 to 7, the cargo container may operate in a folding mode and a fixed mode.

Before the folding mode is performed, the cargo container may perform the following preparatory steps. First, the first side panels 2510 fixed to the frame unit 1000 can be detached by the binding unit 7000.

The first side panels 2510 may then be folded along the plurality of fold lines 2700 so as to be superimposed on the inner side of the second side panels 2550. When the preparatory processes are completed, the folding mode of the cargo container can be performed.

As described above, the folding mode and the fixed mode can be controlled in accordance with the direction of rotation of the lead screws 3000.

In the folding mode, a plurality of the lead screws 3000 may be rotated by the user in one direction. For example, the lead screws 3000 may rotate in the R + direction.

The guide brackets 4000, the calibration brackets 5300 and the connecting members 5700 located at both ends of the lead screw 3000 are rotated by the rotation of the lead screws 3000 in the R + And can be linearly moved toward the inside toward the screw holder 3100. [

More specifically, when the lead screws 3000 are rotated in the R + direction, the first guide brackets 4030 can be moved in the B direction. At this time, the connecting members 5700 and the calibration brackets 5300, which are continuously positioned with the first guide bracket 4030 in one direction, can be simultaneously moved in the B direction.

The other ends of the first side frames 1510 connected to the first guide brackets 4030 and the other ends of the calibration frames 5500 connected to the calibration brackets 5300 are spaced apart from each other by a predetermined distance D 2 And can be moved in the B direction side by side.

When the lead screws 3000 are rotated in the R + direction, the second guide brackets 4050 can be moved in the A direction. At this time. The connecting members 5700 and the calibration brackets 5300 continuously positioned with the second guide bracket 4050 in the other direction can also be simultaneously moved in the A direction. Accordingly, the other ends of the second side frames 1550 and the other ends of the calibration frames 5500 can be moved in the A direction while maintaining a predetermined gap therebetween.

The first side panel 2510 and the second side panel 2550 can be slidably moved by the movement of the first and second side frames 1510 and 1550 and the calibration frames 5500. [ In other words, the lower ends of the first and second side panels 2510 and 2550 can be gradually tilted toward the lead screw holder 3100. At this time, the lowering of the upper frames 1100 by folding can be continued until the first projections 6100 and the second projections 6500 are in contact with each other.

When the first projections 6100 and the second projections 6500 are brought into contact with each other, the folding of the cargo container can be completed.

Conventional folding type containers for freight are separated and assembled at the time of folding to reduce the volume of the container, resulting in a long time and troublesome user.

However, since the cargo container according to the embodiment of the present invention can be controlled only by rotation of the lead screws without being separately assembled and assembled, the efficiency of the user can be improved by improving the convenience and volume, .

In the fixed mode, the plurality of lead screws 3000 may be rotated in the other direction by the user. For example, the lead screws 3000 may be rotated in the R-direction.

The guide brackets 4000 positioned near the lead screw holder 3100 are linearly moved toward the opposite ends of the lead screw 3000 by the rotation of the lead screws 3000 in the R direction .

More specifically, when the lead screws 3000 are rotated in the R-direction, the first guide brackets 4030 can be moved in the B 'direction. At this time. The connecting members 5700 and the calibration brackets 5300, which are continuously positioned with respect to the first guide bracket 4030 in one direction, can also be moved in the B 'direction at the same time. The other ends of the first side frames 1510 connected to the first guide brackets 4030 and the other ends of the calibration frames 5500 connected to the calibration brackets 5300 are spaced apart from each other by a predetermined distance D 2 And can be moved in the direction B '.

When the lead screws 3000 are rotated in the R-direction, the second guide brackets 4050 can be moved in the A 'direction. At this time. The connecting members 5700 and the calibration brackets 5300 continuously positioned with the second guide bracket 4050 in the other direction can also be simultaneously moved in the A 'direction. Accordingly, the other end of the second side frames 1550 and the other end of the calibration frames 5500 can be moved in the A 'direction while maintaining a constant interval D 2 .

Movement of the first and second side frames 1510 and 1550 and the calibration frames 5500 causes the first side panels 2510 and the second side panels 2550 ) Can be erected vertically.

Thereafter, the folded first side panels 2510 may be unfolded. The first side panels 2510 may be fixed to the frame part 1000 again by the binding part 7000. [

The cargo container according to the embodiment of the present invention has been described above. The cargo container may include a frame portion, a panel portion, a lead screw, a guide bracket, a projection portion, and an calibration portion, so that the cargo container can be operated in a fixed mode or a folding mode in accordance with the loading or unloading of the cargo. Accordingly, the volume in the folding mode is reduced, and the stacking and transporting is facilitated, so that a highly efficient container for storage can be provided that is easy to store and transport.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
