Reference numeral 25 denotes a support shaft installed horizontally between the support frames 21 and 23, and a coil spring 27 externally fitted around the vertical shaft is compressed between the support shaft 25 and the bottom piece 26 of the support frame 23 of the lower half body 15. It will be intervened.

FIG. 5 is a plan view of the shelf board 12. Two protrusions 28 which can be inserted into the elongated holes 10 and the notch holes 17 of the both side boards 6 are protruded from both sides of the rear part of the shelf board 12. A locking pin 29 that can be inserted into and removed from the hole in the pedestal 13 of the both side plates 6 is attached to the front side.

Next, the relocation of this shelf board 12 will be explained.

First, as shown in FIG. 6, the protrusions 28 on both rear sides of the shelf boards 12 are inserted into the horizontal parts 8 of the elongated holes 10, and products are stored and placed on each shelf board 12, and the container 1 is opened. It is something that is transported.

After the transfer, the protrusions 28 on both rear sides of each shelf board 12 are inserted into the inclined parts 9 of the elongated holes 10, and the products are taken out from the upper shelf board 12. The products on each shelf board 12 are discharged by tilting the shelves 12.

When transporting the container 1 after discharging the products, the container 1 becomes bulky.
When the shelf board 12 in which 8 is inserted is pulled out to the front side, the protruding body 28 of the shelf board 12 moves from the elongated hole 10a onto the next protruding guide piece 16 as shown in FIG. 12 in the clockwise direction A, the protruding body 28 touches the protruding guide piece 16.
At the same time, it is stopped by the stopper plate 18 via the gap L.

Therefore, with the protruding body 28 locked to the stopper plate 18 and the shelf board 12 pulled out and tilted clockwise, the shelf board 12 is gradually moved as shown in FIG. While lowering the
At the position of the protruding guide piece 16 of the lowest notch hole 17a, while rotating the shelf board 12 counterclockwise in the opposite direction to the above, place the protruding body 28 on the protruding guide piece 16 through the gap L. If the shelf board 12 is pushed in horizontally toward the rear in the C direction, the shelf board 12 can be stored at the lowest level with the protrusion 28 inserted into the notch hole 17a as shown by the two-dot chain line in the figure.

Using this method, the shelf board 12 of the lowest elongated hole 10a is sequentially inserted into the lowermost notched hole 17a, and the next elongated hole 1 is
The shelf board 12 of 0b is inserted into the next notch hole 17b, and the shelf board 12 of elongated hole 10c is inserted into the elongated hole 10a, and the shelf board 12 of elongated hole 10d is inserted into the elongated hole 10d.
When the shelf board 12 of the long hole 10e is transferred to the notch hole 17c and the shelf board 12 of the elongated hole 10e to the notch hole 17d by the above method, the shelf board 12 disappears from the upper half 14 as shown in FIG. Since the shelf boards 12 can be stored in the lower half body 15 in multiple stages, the upper half body 14 can be stored in the lower half body 1 next.
5, the height of the entire container 1 can be halved as shown in FIG.
The container 1 after use can be made extremely compact.

Moreover, since the shelf board 12 can be transferred by using the L between the stopper plate 18 and the protruding guide piece 16 without taking out the shelf board 12 to the outside of the container 1, the work efficiency is improved. can be dramatically improved.

Note that the upper half of the back plate 4 is folded toward the front via the hinge part 5, and then the upper half 1 of one side plate 6 is folded.
4 and both frames 7a, 11 of the upper half 14.
a from both frames 7a and 11b of the lower half body 15, fold the support shaft 25, and use the support point to remove the other side plate 6.
Fold it to the side. When lifting this upper half body 14, the support shaft 25 is guided into the elongated hole 24 while being elastically biased by the coil spring 27.
The lifting work becomes smooth. Then, when the other side plate 6 is folded onto the one side plate 6 using the same method as above using the pivot as a fulcrum, the entire container 1 is folded into a compact state with half the height. It will become.

Next, when using the folded container 1, that is, when storing products, lift the side plates 6, 6 and the back plate 4 from the folded state to their original positions and return them to the state shown in FIG. Then, contrary to the folding process, the uppermost shelf board 12 is pulled out toward the front so that its protruding body 28 moves from the notch hole 17 onto the protruding guide piece 16, and the shelf board is removed from the protruding guide piece 16. 1
If you tilt it while rotating 2 clockwise,
The protruding body 28 is locked to the stopper plate 18, and in this state, it is lifted upward using the stopper plate 18 as a rail, and is inserted into the elongated hole 10 of the uppermost stage.
While keeping the shelf board 12 horizontal at position e, move the protruding body 28 onto the protruding guide piece 16 and close it to the elongated hole 1.
When transferred to the horizontal section 8 of 0e, the shelf board 1 will return to its original state.
2 can be transferred. Similarly,
Each shelf board 12 is attached to each protrusion 2 in the horizontal part 8 of each elongated hole 10.
When 8 is transferred to be transferred, the product becomes ready to be stored.

As described above, the foldable container in this embodiment is foldable and can store all the shelf boards 12 in the lower half 15 of the container 1 when folded. Since there is no need to take out the shelf board 12 from the container 1 every time it is taken out, the shelf board 12 can be stored with high efficiency and the shelf board 12 can be returned after being stored.

The foldable container of this embodiment is used as described above. Since a pair of stopper plates 18 are vertically projected from the both side plates 6 with a predetermined distance from the guide pieces 16 protruding from the lower edge, the position of the shelf board 12 can be adjusted. When the shelf board 12 is pulled out for replacement, the protruding body 28 on the rear side of the shelf board 12 is pulled out away from the guide piece 16 and is locked to the stopper plate 18. The protruding body 28
The shelf board 12 can be moved by raising and lowering the shelf board 12 in an upwardly inclined state while following the stopper plate 18, that is, using it as a rail. The work of changing the position of the shelf board can now be done easily without the large-scale effort required to change the position. As a result, even when folding the container 1, the shelf board 12 attached to the upper half 14 of both side plates 6 can be easily moved and attached to the lower half 15, making the folding work of the container 1 easy. It can be made into something.

Further, the stopper plate 18 is attached to the upper body 1.
The lower end 1 of the stopper plate 18a on the upper half 14 side is divided into two parts: the 4 side and the lower half 15 side.
9 and the upper end portion 20 of the stopper plate 18b on the lower half body 15 side, the upper half body 14
Even when folding, the stopper plates 18 do not come into contact with each other and become an obstacle to folding.

In the above embodiment, a stopper plate is provided on a pair of both side plates to protrude vertically at a position with a predetermined distance from the guide piece, but the distance between the guide piece and the stopper plate is The specific length of the space does not matter as long as the protruding body of the shelf board is movable.

Furthermore, the holes drilled in the rear sides of both side plates may have a shape that allows the protruding body of the shelf board to be inserted and removed and that the shelf board can be supported in a tiltable manner, such as the long hole in the shape of an oval in the above embodiment. It doesn't matter, and the number doesn't matter. moreover,
In order to store all the shelves in the lower half when the container is folded, a long hole for storing the shelves may be made in place of the notch hole made in the lower half.

In addition, the attachment/detachment structure and folding structure of the upper half body and lower half body are not limited to those of the above embodiments, and any structure may be used as long as the both side plates are divided into two and folded.

(Effect of the invention) As described above, in the foldable container of the present invention, the pair of stopper plates are arranged at a predetermined distance from the guide pieces bored at the lower edges of the holes in the side plates. Since the protrusions are provided vertically on both side plates, when pulling the shelf board so that the protrusions move from the holes in the side plates onto the guide pieces, the protrusions will engage the stopper plate if you pull it slightly towards you. Therefore, with the shelf board inserted into the container, the shelf board can be raised and lowered so that its protruding body is aligned with the stopper plate, and therefore the shelf board cannot be pulled out from the container as in the past. There is no need to go through the trouble of repositioning the shelves, or you don't have to take up extra space outside the container by temporarily placing the shelves outside the container. This has the remarkable effect of making it easier and minimizing the work space of the container.

As a result, when folding the container, the shelf board attached to the upper half can be easily repositioned and attached to the cutout or slotted hole in the lower half, making folding the container less of a tedious task. This means that the process can be completed in a short time, making this type of foldable container functionally superior.

Similarly, when a folded container is returned to its original state, it can be easily done by lifting the shelf board while using the stopper plate as a rail, so there is an advantage that there is no need to take out the shelf board outside. .

Furthermore, since the stopper plates protruding in the vertical direction of both sides of the container have a foldable structure, there is an advantage that the stopper plates do not get in the way structurally when folding the both sides.
