On the other hand, the side hinge 140 is coupled to the upper end of the upper sidewall 131 or the lower end of the lower sidewall 133, it is coupled to the upper and

lower plates

110, 120 may be able to adjust the angle up to about 90 degrees.

The structure in which the door 160 of the container 100 of the present invention is opened is shown in FIGS. 3 to 4. 3 is a view in which the door 160 of the foldable container 100 according to the present invention is opened, and FIG. 4 is a view for explaining the rotation and sliding structure of the door 160.

The container 100 supports the support frame 111 disposed at the edge of the lower plate 110, the corner member 112 fixed to the end of the support frame 111, and supports the door 160. Removably penetrates the guide rail 170 disposed on the upper portion of the support frame 111 along the frame 111, the guide post 174 disposed on the end of the guide rail 170, and the guide rail 170. It further includes a fixing pin 175 is installed. Here, the guide rail 170 includes a lower guide rail 171 and an upper guide rail 172 spaced apart a predetermined distance from the upper portion of the lower guide rail 171, the fixing pin 175 is the upper and lower guide rails ( 171, 172 is disposed through the up and down.

The door 160 has guide protrusions 164 extending from the side edge thereof. For example, the guide protrusion 164 may have a cylindrical shape and may be rotatable.

First, the operation of opening the door 160 in the closed state on the container 100 is as follows. First, the lock state is released to open the door 160 coupled to the container 100. The container 100 may include a fastener 165 provided on the side of the door 160 and a fastener 125 provided at an edge of the side wall 130, and the fastener 165 coupled to the fastener 125. By releasing the lock state is released to enable the opening of the door 160. In the process of opening the door 160, the door 160 rotates the guide protrusion 164 about its axis.

That is, the door 160 is a container in the first vertical position with the guide protrusion 164 as the axis of rotation in the state in which sliding between the guide rail 170 by the fixing pin 175 and the guide post 174 is prevented It rotates to the outside of 100.

In the present invention, the container 100 is characterized in that the door is first opened to the outside of the container during the folding operation process. That is, since the door is rotated in the outward direction of the container 100 and is deployed to the outside of the container, the door does not need to be folded by the operator. Therefore, the greatest advantage of the present invention is that it is possible to fundamentally prevent a safety accident that may occur in the process of folding the container.

In a state in which the door 160 is rotated about 90 degrees in the outer direction of the container 100 and placed parallel to the ground, the fixing pin 175 is removed from the guide rail 170. When the fixing pin 175 is removed, the guide protrusion 164 of the door is slid along the guide rail to be accommodated in the container.

The guide protrusion 164 moves along the guide rail 170 to the inside of the container 100, so that the guide protrusion 164 may be accommodated inside or above the lower plate 110 of the container 100 of the door 160. Here, the guide protrusion 164 performs any one or more of the sliding motion and the rolling motion. That is, the guide protrusion may be formed of a roller (not shown) to allow relative rotational movement with respect to the door for rolling motion.

Hereinafter, a process of stably folding through the folding structure of the foldable container will be described with reference to FIGS. 6 to 11.

First, FIG. 6 illustrates a state before the container 100 is folded, and the side wall 130 and the door 160 are vertically disposed without change.

In FIG. 7 and FIG. 8, the door 160 is rotated in an outward direction of the container 100 to open. In FIG. 7, the doors 160 disposed on the left and right sides of the container 100 rotate in counterclockwise and clockwise directions, respectively.

By doing so, if the door 160 of the container 100 rotates inward, the worker who may be inside the container 100 may be injured. Since the door 160 is relatively light in weight, about two workers may be manually folded and unfolded.

In FIG. 9, the door 160 is moved through the process of moving the guide protrusion 164 to the inside of the container 100 along the guide rail 170 in a state in which the door 160 is rotated and placed in parallel to the ground. A state in which the container 100 is accommodated in the inner lower plate 110 is shown.

10 illustrates a process in which the upper sidewall 131 and the lower sidewall 133 are folded by the main hinge 150 disposed on the sidewall 130. Preferably, the upper sidewall 131 and the lower sidewall 133 maintain the same size and shape so that the main hinge 150 may be disposed on the center portion of the sidewall 130.

In FIG. 11, the upper sidewall 131 and the lower sidewall 133 are completely folded so that the upper sidewall 131 is stacked on top of the lower sidewall 133. As a result, the door 160 is received on the lower plate 110 of the container 100 in a sliding manner, and the left and right side walls 130 are rotated by the main hinge 150 at the center to be folded. As a result, the upper and

lower side walls

131 and 133 are sequentially stacked on the door 160 accommodated therein. As a result, the door 160 and the upper and

lower sidewalls

131 and 133 are filled between the upper plate 120 and the lower plate 110.

As described above, the present invention allows the door 160 to be loaded into the container 100 in a convenient and stable manner through the rotation and sliding movement of the door 160, and through the main hinge 150 and the side hinge 140 Enables stable folding operation of the upper and lower sidewalls (131, 133).
