Description

[Detailed Description of the Invention] The present invention relates to a box-shaped pallet consisting of a base body and four side walls arranged upward from the four sides of the base body.

Conventionally, in box-shaped pallets like the one described above, items are loaded from the open top and transported by forklift truck or stacked and stored, and items are taken out from the open top. I'm going from there. In this case, there is no problem if the height of the box-shaped pallet is low, but if the box-shaped pallet is made high for efficient transportation and storage, the side walls will get in the way and make it difficult to load and remove items. It will not be possible to do so. As a solution to these problems, for example,
As seen in Publication No. 136643, one of the four side walls is composed of an upper wall portion that can be freely connected to the adjacent side wall, and a lower wall portion that is attached to the upper wall portion so as to be vertically swingable. However, a type has been provided in which the lower wall surface portion is swung upward to facilitate the removal of items. Also, in 1977-
As seen in Publication No. 37219, one side wall is divided into an upper frame and a lower frame, and these are connected by support pins so that they can swing relative to each other, and the support pins are supported by the other side wall, so that both the upper and lower frames Types that can be vertically swung separately are provided.

However, in the above-mentioned method in which both the upper frame and the lower frame are oscillated, the oscillation structure via the support pins becomes complicated. In addition, rigidity with other side walls, especially in a state in which both frames can be swung, is insufficient. In this case, it is sufficient if the other side wall is fixed and erected from the base frame, but in the case of a type in which the other side wall is folded (swinged) as seen in, for example, Japanese Utility Model Application Publication No. 50-136643, If the rigidity is insufficient, the other side walls will be expanded, so a type that swings both upward and downward cannot be adopted.

The purpose of this invention is to create a box-shaped pallet whose side walls can be folded, but the upper and lower parts of the front side wall can be vertically swung separately, and the left and right side walls can be connected with sufficient rigidity. The point is to provide the following.

In order to achieve the above object, the box-shaped pallet of the present invention includes a base body, a rear side wall whose lower end is connected to the base body so as to be able to swing vertically, and rear edge portions on the left and right edges of this rear side wall. An intermediate device having left and right side walls connected to each other so as to be swingable from side to side, and a front side wall disposed between the front edges of these left and right side walls, and having this front side wall attached to an attachment/detachment tool that allows the adjacent left and right side walls to be attached and detached. an upper part whose lower end is attached to the upper end of the intermediate part so as to be vertically swingable; and a lower part whose upper end is attached to the lower end of the intermediate part so as to be vertically swingable; Furthermore, locking devices are provided which are integrated into the left and right side walls adjacent to the upper and lower parts.

According to the configuration of the present invention, when assembled, the left and right side walls and the wide intermediate portion are integrated by the attachment/detachment tool, so that they are made into a rigid body. Then, by unlocking the locking tool in this state, the upper part or the lower part can be opened. Furthermore, even if both the upper part and the lower part are opened, the connection with the left and right side walls and rigidity are maintained due to the presence of the intermediate part. For folding, after releasing the integration with the left and right side walls using the attachment/detachment tool and the locking tool, the left and right side walls are folded onto the surface of the rear wall, and then the front wall is positioned above or below the rear wall. Just fold it onto the base.

An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 designates a box-shaped pallet consisting of a base body 2 and four side walls disposed upward from the four sides of the base body 2, that is, a front wall 3, left and right side walls 4, 5, and a rear wall 6. Base body 2 and all side walls 3,
4, 5, and 6 are formed in a mesh shape from a metal material, a resin material, or a combination of both materials, and legs 7 are suspended from the bottom surface of the base plate 2.
A fork insertion space 8 is formed below. Furthermore, each leg 7 is provided with a locking portion 9 that can be placed on the upper edges of the left and right side walls 4, 5, thereby allowing the box-shaped pallets 1 to be stacked. Said four side walls 3, 4,
The front side wall 3 of 5 and 6 is detachably attached to the adjacent left and right side walls 4 and 5, and an intermediate section 3A, and this intermediate section 3
The upper part 3B has its lower end attached to the upper end of the intermediate part 3A so as to be swingable up and down, and the lower part 3C has its upper end attached to the lower end of the intermediate part 3A so as to be able to swing up and down. The left and right side walls 4, 5 and the rear side wall 6
and is foldable. That is, the rear edge of the left side wall 4 is connected to the connector 1 with respect to the left edge of the rear side wall 6.
0, and the rear edge of the right side wall 5 is connected to the right edge of the rear side wall 6 by the connector 1.
The lower end of the rear wall 6 is connected to the base body 2 via a connector 12 so as to be swingable up and down. Therefore, for example, after swinging the left side wall 4 so as to be in contact with the rear side wall 6 and then swinging the right side wall 5 so as to be in contact with this left side wall 4, the rear side wall 6 is moved forward along with the left and right side walls 4 and 5. By swinging the base body 2, the left and right side walls 4, 5 and the rear wall 6 can be folded in a stacked state on the base body 2. In the case of such a folding type, the front side wall 3 is configured to be detachable from the left and right side walls 4 and 5. That is, the intermediate portion 3A
Attachment/detachment tools 13 for the left and right side walls 4, 5 are provided on both sides. The upper part 3B and the lower part 3C are:
It is connected to the intermediate portion 3A via connectors 14 and 15 so as to be able to swing up and down. Further upper part 3B
On both sides of the upper end and on both sides of the lower end of the lower part 3C, locking tools 16 and 17 are provided to integrate these 3B and 3C with the left and right side walls 4 and 5.

Before performing the above-mentioned folding, the attachment/detachment tool 13 and the connectors 14, 15 are released, the front wall 3 is removed from the left and right side walls 4, 5, and then the front wall 3 is folded onto the uppermost rear wall 6, or This front side wall 3 is positioned on the base plate 2 before folding. In use, the left and right side walls 4 and 5 are integrated with the intermediate portion 3A using the attachment/detachment tool 13,
Then, the upper part 3B and the lower part 3C are integrated with the left and right side walls 4 and 5 by locking tools 16 and 17. When putting items (agricultural products, etc.) into the box-shaped pallet 1 assembled in this way, the locking tool 16
The upper part 3B is moved downward by releasing the upper part 3B, and the upper part 3B is opened through the opening in the upper front surface. In addition, when taking out (dispensing) an item, the locking tool 17 is released, the lower part 3C is moved upward, and the item is taken out through the opening created in the lower front part.

According to the present invention having the above configuration, when assembled, the left and right side walls and the wide middle part can be integrated with the attachment/detachment tool, and these can be made into a rigid body.
An attachment/detachment tool that provides a sufficiently rigid body can be placed within the width of the intermediate portion. In this state, by integrating the upper and lower parts with the adjacent side walls via locking devices, a box-shaped pallet of sufficient height can be formed, allowing for efficient transportation and storage. be able to. In addition, by unlocking the locking tool and swinging only the upper part downward, the loading of items can be easily carried out using the part opened by the upper part, and furthermore, the loading of items can be easily carried out by unlocking the locking tool and swinging only the upper part downward. This can be easily done by swinging only the lower part upward, using the part opened by the lower part. Even if both the upper part and the lower part are opened, the presence of the wide middle part allows the connection and rigidity with the left and right side walls to be maintained, and it is possible to prevent the left and right side walls from expanding. As described above, the present invention can provide a box-shaped pallet with foldable side walls but with the upper and lower parts of the front side wall individually swingable up and down, due to the simple structure of the present invention having an intermediate section.
