Description

[Detailed description of the invention] (Industrial application field) This invention is a container used for transporting cargo within a factory or to another location such as another company's factory, and more specifically, a folding container. About flexible containers.

(Prior art) The applicant filed an application for utility model registration regarding containers dated June 13, 1985 (Utility model registration
200550), and the gist of this invention is that, as shown in FIG. A pair of protrusions 33 formed on the rear side of the shelf board 32 are inserted into the elongated hole 31 to lift the plurality of shelf boards 32 upward and make them tiltable. It facilitates the loading and unloading of products.

(Problems to be solved by the invention) However, when the container according to the above invention was used, the following new problems occurred.

When a container is not in use, that is, if all the shelves are empty, the space of the container is extremely wasted during transportation or in the factory.In particular, it is extremely difficult to stack unused containers in multiple tiers due to the height. Because it was dangerous, space in the container when not in use became a major problem. Moreover,
In the folding structure of the container, a new problem has arisen in the storage space of empty shelves that interfere with folding.

In order to solve the main problems as mentioned above,
This invention was devised to make the container foldable, and its purpose is to make it possible to fold the container when not in use, and to create a dedicated storage area for empty shelves. .

(Means for Solving Problems) In order to achieve the above object, the present invention is based on the invention previously developed by the applicant, and the following points are newly devised.

Both sides of the container are divided into upper and lower halves so that they can be folded, and in addition, cutouts for inserting the protruding parts of the empty shelf boards are provided at the top and bottom of the rear sides of the lower halves of both sides in the same line as the elongated holes. The above purpose was achieved by newly devising the above-mentioned configuration.

(Function) In the container configured as described above, when all the shelf boards 12 are empty and the container is not in use, the upper half 15 of the side boards 6, 6a is moved to the lower half 15.
The shelf board 12, which can be folded separately from a, and which becomes empty when folded, is inserted into each notch 28 formed in the lower half 15a of the side boards 6, 6a. can be inserted, so all the shelf boards 12 can be easily stored in the lower half 15a, and the height of the entire container can be folded to at least half or less.

(Example) Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

Fig. 1 is an overall schematic perspective view of the container 1 as an example with all shelf boards removed. The upper half of the face plate can be folded toward the front using a hinge portion 5.

Fig. 2 is a plan view of Fig. 1, and Fig. 3 A is a sectional view taken along the line A-A of Fig. 2. In the figure, 6 and 6a are both side plates, and U-shaped frames 7 and 7a on the rear side. This is made up of five substantially rectangular long holes 10 having a horizontal portion 8 and an inclined portion 9, which are vertically bored at predetermined intervals, and corresponding to the long holes 10 on the front side. U-shaped frame body 11, 11a
A cradle 13 for placing the shelf board 12 on the front side is protruded from the side board 6, 6a.
5a refers to the planar U-shaped bones 7b and 11 exposed from the front and rear frames 7 and 11 of the lower half body 15a, as shown in FIG.
The frames 7 and 11 of the upper half body 15 are divided into two parts to be externally fitted to the upper half body 15. Reference numeral 14 indicates a guide rail having an L-shaped cross section and provided in front of each of the long holes 10 except for the uppermost long hole 10.

28 is a frame body 7 on the rear side of the side plates 6, 6a;
The protruding body of the shelf plate can be inserted into and removed from four notches formed in the same row as the elongated hole 10 on the lower half body 15a side of 7a. 16 is the upper half 1 of the side plates 6, 6a.
A pair of support frames 18 project downward from the horizontal ribs 17 of the side plates 6, 6a, and the lower half 1 of the side plates 6, 6a.
5a is an upwardly U-shaped support frame that projects upward, and elongated holes 19 are bored in the frames 18a and 18b on both sides. Reference numeral 20 denotes a support shaft installed horizontally between the support frames 16 and 18, and a coil spring 23 externally fitted around the vertical shaft is compressed and interposed between the support shaft 20 and the bottom plate 21 of the support frame 18. It will be done.

FIG. 5 is a plan view of the shelf board 12, in which a pair of protrusions 24 that can be inserted into the elongated holes 10 of the side boards 6, 6a protrude from both sides of the rear part, and the front part of the shelf board 12. An engagement pin 26 having a protruding pin 25 on the tip side that can be inserted into and removed from the hole in the pedestal 13 of the side plates 6, 6a is attached to the side.

The present invention is constructed as described above, and when the product is stored and placed on the shelf board 12 during use, the lower shelf board 12 is placed horizontally and the upper shelf board 1 is placed horizontally.
2 is stored by tilting it upward.
Conventionally, the shelf board 12 was always located in the container because it was in a fixed state, but in the present invention, when the horizontal shelf board 12 is pulled out to the front side, the protrusion 24 at the rear of the shelf board 12 is inserted into the elongated hole 10. From the horizontal portion 8, it moves further onto the guide rail 14 and is pulled out as shown in FIG. 7 until it is stopped by the stripper plate 27.

As a result, compared to conventional shelf boards, the shelf board 12 protrudes to the front side of the container, making it easier to store products to the back of the shelf board 12.

After the products are stored and placed on the lower shelf board 12 in this way, when the shelf board 12 is pushed to the back side again, the protrusion 24 will be inserted into the elongated hole 10 from the guide rail 14. The shelf board 12 is stored in the container 1 without jumping out to the front side, and returns to its original state.

This is done sequentially from the lower shelf board 12 to the upper shelf board 12.
By storing the products up to this point, the storage of the products into the container 1 is completed.

On the other hand, when taking out the products stored on each shelf board 12, contrary to the above, the products are taken out sequentially from the upper shelf board 12, but in this case, the shelf board 12 to be taken out is placed on the front side in the same way as above. Shelf board 12 when pulled out
The protruding bodies 24 on both rear sides of the shelf board 1 can be easily moved from the horizontal part 8 of the elongated hole 10 to the guide rail 14 side.
2 can be pulled out to the front side, and as a result, products on the back side of the shelf board 12 can also be taken out extremely smoothly.

As described above, by changing the shelf board 12 from the conventional fixed type to a pull-out type, it is now possible to extremely easily take in and take out products from the back side of the shelf board 12.

Note that the length and shape of the guide rail 14 shown in the above embodiments are not limited to those in the above embodiments.

Next, if all the products are taken out from each shelf board 12 and the container 1 is no longer used, or if the products are transported in the container 1 and the shelf board becomes empty after that, each shelf board 12 to both side plates 6,
The protrusions 24 of each shelf board 12 are inserted into the notches 28 made in the frames 7, 7a on both rear sides of the lower half 15a of the lower half 15a of the both side boards 6, 6a. Four shelf boards 12 are housed in a multistage manner in the lower half body 15a of 6, 6a as shown in FIG. 8A.

Thereafter, the upper half 4a of the back plate 4 is folded toward the front via the hinge portion 5 to obtain the state shown in FIG. 8B.

Next, lift the upper half 15 of one side plate 6,
While removing the upper half 15 from the lower half 15a, the other side plate 6a side is folded onto the upper half 4a of the back plate 4. When the upper half body 15 is removed, the upper half body 15 is
The lifting of the upper half body 15 from the lower half body 15a becomes extremely easy since it is extremely light and smooth compared to its weight, and the support shaft 20 is lifted through the elongated hole 10 ( (It will be in the state shown in Figure 8c).

Thereafter, when the other side plate 6a is folded onto the one side plate 6 in the same manner as described above, the entire container 1 is folded into a compact state with half the height as shown in FIG. 8D. As a result, the height space is less than half of the conventional one, so another container 1 can be placed on top of this folded container 1.
can be stacked, making it easy to store and transport the container 1 when not in use.

In the above embodiment, all the shelf boards 12 are provided with long holes 10.
The protruding body 24 was inserted into the notch 28 and stored, but the shelf board 12 with the protruding body 24 inserted into the long hole 10 of the lower half 15a was left as it was and the protruding body 24 was inserted into the notch 28. It is also possible to remove only a certain shelf board 12 and insert it into the notch 28 of the lower half body 15a.

Therefore, the number of notches 28 does not need to match the number of shelf boards 12 and may be less than that number.

Further, the shape of the elongated hole 10 bored in the rear side of the side plates 6, 6a is not limited as long as it can lift and tilt the shelf board 12, and the shape of the notch 28 is also limited to the above embodiment. It's not a thing.

Further, the structure for attaching and detaching the upper half body 15 and the lower half body 15a, the shape of the spring 23, and the attachment position are not limited to those in the embodiment. In addition, the structure for engaging and disengaging the engaging pin 26 attached to the front side of the shelf board 12 and the pedestal 13 is not limited to the embodiment. Further, although the container 1 of the above embodiment is provided with a back plate 4, the back plate 4 is not necessarily an essential requirement of the present invention.

(Effects) The present invention is implemented as described above, and the main effects of the present invention are as follows.

On the rear side of the lower half of the side panels, a notch is formed separately from the elongated hole, so each empty shelf board can be stored inside the lower half using this notch. We were able to make the upper body foldable.

Since at least both side plates can be folded inward, the height of the entire container becomes at least half or less, making the entire container more compact. This has the special effect of minimizing the storage and transportation space of the container when not in use. I got it.

The above-mentioned effects are unique to the present invention and have great practical value compared to conventional containers.
