[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box having side plates arranged on each of the four sides of a bottom plate, and particularly to a box suitable for use as a returnable box for storing mechanical parts and the like and for repeated use. [Summary of the Invention] The present invention connects four side plates to the bottom plate in a rotatable manner, and attaches a reinforcing frame to the peripheral edge of the side plate other than the connecting portion with the bottom plate. A removable connecting means is attached to each of the 5 parts, so that it can be expanded into a plate shape and transported or stored in a flat state. K. Prior Art] For example, as a returnable box that is used repeatedly to store mechanical parts, boxes made of, for example, Plus Deck Sea 1 have traditionally been used.
Four side plates are continuous on the four sides of the bottom plate.

[The four side plates were connected laterally as they were pulled together, and a reinforcing frame was fitted to the upper ends of the side plates. Furthermore, in the case of the box, connect both ends of the reinforcing frame on both sides with a fixing reinforcing device made of a separate member, and use a plastic bottle or the like to connect the reinforcing device and the reinforcing frame. I applied oil to the side panels to secure them in place. [Problems to be Solved by the Invention] According to such conventional returnable boxes, four side plates are continuous in the horizontal direction on the four sides of the bottom plate.
It was not possible to fold it laterally to this tc. Also, unless the corner reinforcements were removed, it could not be unfolded into a single flat plate. Furthermore, even if the corner reinforcements are removed, there is an inconvenience that many parts may be lost when used as a returnable box. When it is used, it has to be reassembled, which requires a lot of effort and time, and has disadvantages. For these reasons, conventional returnable boxes have the disadvantage of not being able to be folded or unfolded, and requiring a large amount of space to store and transport empty boxes. The present invention has been made in view of these problems, and allows for easy expansion without removing the reinforcing frame or corner reinforcing tools, thereby saving a large amount of space when storing and transporting empty boxes. In addition to avoiding the need for
The object is to provide a box that can be easily assembled as needed. ] (Means for Solving the Problems) The present invention provides a box having side plates connected to each of the four sides of a bottom plate, in which the side plates on the four sides are rotatably connected to the bottom plate, and the side plates on the four sides are rotatably connected to the bottom plate. A reinforcing frame is attached to the peripheral edge of the side plate other than the connection 81 with the bottom plate, and detachable connection means are attached to both ends of the side plate. By releasing the connecting means, it becomes possible to separate the side plates adjacent to each other in the lateral direction, and it becomes possible to rotate the side plates with respect to the bottom plate and unfold them into a flat state. [Example] The present invention will be described below with reference to an illustrated embodiment. Figs. 1 to 4 do not show a returnable box according to an embodiment of the present invention, and the returnable box is, for example, a hollow plastic deck. The bottom plate 10 is made of a sheet. Side plates 11.12 are connected to the long and short sides of the bottom plate 10, respectively. Bottom plate 1
0 for rotation. and four side plates 11
．． A reinforcing frame 13 is attached to each peripheral edge of the frame 12, and connectors 14 are attached to both ends of the long-side side plate 11. On the other hand, connectors 15 are attached to both ends of the short-side side plate 12. These connectors 14.
15 constitute the female part and the male part of the removable coupling means, respectively. Next, referring to FIGS. 9 to 14, the structure of the detachable connecting means will be described. The connecting member 14 that constitutes the female part is provided with connecting pieces 18 on the sides and below.
These connecting pieces 18 connect the side plate 1 together with the reinforcing frame 13.
It is designed to be installed on 1. The connector 14 also includes a sliding recess 19, and the slider 20 is movably supported by this recess 19. A claw 21 is integrally formed on the slider 20 as shown in FIGS. 10 and 11, and a spring receiver 23 shown in FIGS. 12 and 13 is supported via a pin 22. . This spring holder (pu 23) is designed to receive a coil spring 24.The other end of the coil spring 24 is connected to a bottle-shaped protrusion 2.
5 to be supported by this connector 14. Further, this connector 14 is formed with a locking recess 26 and a locking wall 27. Note that the recess 26
In this case, a through-hole structure may be used. On the other hand, as shown in FIGS. 15 and 16, a connecting piece 29 is formed on the connecting tool 15 constituting the male part of the connecting means, and these two connecting pieces connect the reinforcing frame 13.
and the side plate 12. Furthermore, this connector 15 has a single-shaped locking portion 30 as shown in FIG.
This locking portion 30 allows the connecting tool 14 to be
It is adapted to be engaged with the slider 20 of. Further, locking protrusions 31 are provided on the upper and lower sides of the locking portion 30, respectively, and are adapted to be received in the locking recess 26 of the connector 14. Also, a locking wall 3 is provided on the top of this connector 15.
2 is formed. The structure of the locking portion 30 includes a locking opening 41 shown in FIG. 17, a locking recess 42 as shown in FIG.
As shown in the figure, the protrusion 31 can be replaced with various structures such as a locking piece 43 without the protrusion 31. In the above configuration, when assembling a flattened box as shown in FIG. 1, as shown in FIGS. 4
The two side plates 11.12 may be bent at right angles and placed adjacent to each other, and the connecting means installed at both ends of these side plates 11.12 may be connected to each other. That is, the long-side connector 14 and the short-side connector 15 may be engaged with each other. This engagement is accomplished by inserting the single-shaped locking portion 30 and protrusion 31 of the male portion 15 into the sliding recess 19 and locking recess 26 of the detail 14, respectively, as shown in FIGS. 5 and 6. That's fine. The 1-shaped locking portion 30 is inserted into the sliding recess 1
9, the arcuate portions forming the outer surface of the claws 21 of the slider 2o are pushed, and the slider 2o moves backward against the coil spring 24. When the locking part 3o gets over the claw 21, the locking part 30 comes to be locked by the claw 21 of the slider 2o, as shown in FIGS. 14.15
become connected to each other. In this way, the box can be assembled into a rectangular parallelepiped shape as shown in FIGS. 1 to 4. In this case, the -F section of the box is open and the upper edges of the side panels 11, 12 are each reinforced by a reinforcing frame 13. Such boxes are used as returnable boxes, and are used repeatedly for storing mechanical parts and the like. Also, since locking walls 27.32 are provided on the outside of the corner connectors 14.15 that are connected to each other, even when such boxes are stacked in multiple tiers, they can be held stably. It becomes possible to do so. Next, when storing or transporting such a box,
It can be flattened as shown in FIGS. 7, 8, and 1. This operation can be accomplished by separating the couplings 14.15 from each other and then opening the side plates 11.12 to the outside. In order to open the connector 171.15, the slider 2o of the connector 14 may be moved against the coil spring 24 by the operating protrusion 34, thereby causing the claw 21 of the slider 20 to move in the opposite direction. It will be separated from the single-shaped locking part 30 of the side connecting part 15. The male portion 14 thereby forming a connecting means.
and the female part 15 are separated from each other, and the side plate 11
．． 12 can be rotated along the bending line 16. Therefore, during transportation or storage, it becomes possible to unfold it completely into a flat plate as shown in FIG. The removable connectors 14, 15, which are attached to the corners of the box, are in each case fixed together with the reinforcing frame 13 to the side panels 11, 12 by means of two of their connector pieces 18. Therefore, even if such a connecting means 14.15 is unfolded flat as shown in FIG. 1, it will not fall out of this box and the parts 14.1
5 is never lost. Such a box also makes it possible to separate the connectors 1/I, 15 as required, thereby making it possible to open the side panels 11, 12 of the box at will. Therefore, it is now possible to take items in and out from the side of the conveyor, etc., as desired.
It has great convenience in terms of functionality. 1 (Effects of the Invention I) As described above, the present invention connects the side plates on the four sides of the box rotatably to the bottom plate, and attaches a reinforcing frame to the peripheral edge of the side plates other than the connection portion with the bottom plate. Roughly speaking, one removable connection stage is attached to each end of the side plate. Therefore, with this configuration, it is possible to deploy the box at will, and the storage and transportation of empty boxes is streamlined. Furthermore, when the box is to be used again as a box, it is only necessary to raise the side plates and connect them using the connecting means, making it possible to easily assemble the box.
