FIG. 1 is a plan view showing an example of the folding transport container according to the present invention, FIG. 2 is a front view of the folding transport container shown in FIG. 1, and FIG. 3 is a view taken along line AA in FIG. FIG. 4 is a sectional view taken along the line BB in FIG. 1, FIG. 5 is a right side view of the folding transport container shown in FIG. 1, and FIG. FIG. 7 is a rear view of the folded transport container shown in FIG. 7, FIG. 7 is a partially exploded perspective view of the folded transport container shown in FIG. 1, and FIG. 8 is a partial sectional view showing the folded transport container shown in FIG. FIG. 9 is a partial cross-sectional view showing a state where the opening / closing door of the folding transport container shown in FIG. 1 is open.

The folding transport container according to the present invention is mounted so as to be rotatable with respect to the upper frame 1, the bottom plate 2, the upper frame 1 and the bottom plate 2, and to the inside with the connecting shaft 3. A pair of opposing side plates 6 composed of an upper side plate 4 and a lower side plate 5 that are connected so as to be bent, and a pair of opposing tilt plates 7 that are rotatably attached to the upper frame 1. Have.

In the folding transport container according to the present invention, a rectangular opening 8 is formed in at least one of the side plates 6, and a guide groove 9 opposed to the left and right peripheral edges of the rectangular opening 8.
And a guide groove 9 '.

In the folding transport container according to the present invention, the opening / closing lid 10 for opening and closing the rectangular opening 8 is provided with the upper door 1.
1, a door locking member 12 connected to the upper door body 11,
And a lower door 13 connected to the door locking member 12.

The upper door 11 and the door lock 12 are connected by a connecting shaft 14. The upper door body 11 and the door body locking member 12 can be bent inward by the connecting shaft 14, but the lower end inner surface of the upper door body 11 and the door body locking member 1
2 cannot be bent outward due to the contact of the upper outer surface. Further, the upper door body 1 is connected by the connecting shaft 14.
When the door 1 and the door locking member 12 are bent inward, the inner surface of the lower end of the door locking member 12 and the outer surface of the upper end of the lower door 13 come into contact with each other, so that the lower door 13 is closed. And bend together.

The door locking member 12 and the lower door 13 are connected by a connecting shaft 15. The door body locking member 12 and the lower door body 13 can be bent outward by the connecting shaft 15, but the lower end inner surface of the door body locking member 12 and the lower door body 1 can be bent.
3 cannot be bent inward due to the contact of the upper outer surface.

Left locking piece 20, and right locking piece 20 ′ movably attached to the right double wall 19 ′ of the locking main body 18 in the lateral direction. The projecting portion 22 formed on the piece 20 is projected into the guide groove 9 to be locked, and the projecting portion 22 ′ formed on the right locking piece 20 ′ is projected into the guide groove 9 ′ by the elastic force of the spring 21 ′. Then, the rectangular opening 8 of the side plate 6 is closed by the opening / closing lid 10.

In the folding transport container according to the present invention, in order to open the opening / closing lid 10 of the square opening 8, fingers are held on the handle 23 of the left locking piece 20 and the handle 23 ′ of the right locking piece 20 ′. The left and right locking pieces 20 ′ are applied by applying a force against the elasticity of the spring 21 and the spring 21 ′.
Is moved laterally, and as shown in the left half of FIG. 2, the protrusion 22 of the left locking piece 20 is retracted from the guide groove 9 and the protrusion 22 'of the right locking piece 20' is retracted from the guide groove 9 '. Thereafter, as shown in FIG. 9, the protrusion 16 and the protrusion 16 ′ of the upper door body 11 are respectively bent into the guide groove 9 and the guide groove while the lid locking member 12 and the lower door body 13 are bent outward by the connecting shaft 15. It may be lowered within 9 '.

Further, in the folding transport container according to the present invention, in order to close the rectangular opening 8 with the opening / closing lid 10, the lid locking portion 12 and the lower lid 13 are bent inward by the connecting portion 15. At the same time, the protrusion 16 and the protrusion 16 'of the upper door body 11 are raised in the guide groove 9 and the guide groove 9', respectively, so that the handle 23 of the left locking piece 20 and the handle 23 'of the right locking piece 20'. Hook a finger to apply a force against the elasticity of the spring 21 and the spring 21 ′ to move the left locking piece 20 and the right locking piece 20 ′ in the horizontal direction, and to project the projection 22 and the right engagement piece of the left locking piece 20. After the protrusion 22 ′ of the stop piece 20 ′ is once retracted into the lid lock section 12, the protrusion 22 of the left lock piece 20 is moved into the guide groove 9 by the elastic force of the spring 21 as shown in the right half of FIG. The spring 21 ′. It suffices locked by projecting the 'projection 22' of the right locking piece 20 into the guide groove 9 'within.

In order to fold the folding transport container according to the present invention, the tilting plate 7 is turned inward, and the upper side plate 4 and the lower side plate 5 are bent inward by the connecting shaft 3 as shown in FIG. At 14, the upper door body 11 of the opening / closing lid 10 and the door body locking tool 12 may be bent inward.

In order to assemble the folding transport container according to the present invention, the pivoting plate 7 is pivoted outward so that the lower end of the pivoting plate 7 is locked around the bottom plate 2 and then the connecting shaft 3 is rotated.
The upper and lower lids 11 and 1 of the opening / closing lid 10 which are bent inward by the upper side plate 4 and the lower side plate 5 which have been bent inward by the connecting shaft 14 and bent inward by the connecting shaft 14.
2 may be bent outward.

In the folding transport container according to the present invention, an upper frame 1, a bottom plate 2, an upper side plate 4, a lower side plate 5, a tilt plate 7, an upper door body 11, a door body locking member 12, and a lower door body 13 are provided. Can be formed of a synthetic resin such as polyethylene or polypropylene, but if the upper door body 11, the door body stopper 12 and the lower door body 13 are formed of a transparent synthetic resin such as polycarbonate, the opening / closing lid 10 is closed. This is more preferable because it is possible to inspect the articles stored therein in the state in which they have been placed.

In the illustrated folding transport container, a rectangular opening 8 is formed in only one of the opposed side plates 6 and an opening / closing lid 10 is attached. The opening 8 may be formed, and the opening / closing lid 10 may be attached.

[0023]

According to the folding transport container of the present invention, when the open / close lid 10 is opened, the open / close lid 10 does not droop greatly downward. Open the lid 10
