(57) [Abstract] [Purpose] To provide a folding type box which is low in cost, excellent in strength, and easy to assemble. [Structure] A foldable box including side plates 2 and 3 and a bottom plate 1, a frame 4 provided on the upper side plate, and pivot plates 5 and 6 rotatably provided on the frame.
And side plates 2 and 3, and fulcrums of hinges connecting the bottom plate 1 and the side plates 2 and 3 are provided at different heights.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container used for storing and transporting various products, and particularly to a container that is easy to assemble and can be folded.

[0002]

[Prior art]

 Conventionally, this type of folding container has not functioned as a folding container unless the height A of the container is equal to or less than the width B of the bottom as shown in FIG.

[0003]

[Problems to be solved by the present invention]

 As shown in FIG. 6, in the conventional folding container, the fulcrum of the hinge that connects the frame 4 and the side plates 2 and 3 and the bottom plate 1 and the side plates 2 and 3 has the same height as the bottom plate 1 and the side plates 2 and 3. Left and right a = a ′, and left and right b = b ′ for the frame 4 and the side plates 2 and 3. Here, as shown in FIG. 7, it is a necessary condition that the side plates 2 and 3 do not come in contact with each other at the center C when folded, and the height A in FIG. 6 must be equal to or less than the width B of the bottom. did not become.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems. The height d of the fulcrum of the bent part hinge 7 connecting the bottom plate 1 and the side plate 2 and the bent part hinge connecting the bottom plate 1 and the side plate 3 are explained. As shown in FIG. 5, the height e of the fulcrum of 8 is the hinge fulcrum 7, 8 of the side plates 2 and 3 connected to the bottom plate 1 by the thickness c of the two side plates when the container is folded. By making it higher, when folding, it is possible to fold the other lower one into the one with the higher hinge fulcrum. Next, the frame 4 and the side plates 2 and 3 will be described. The heights of the fulcrum of the bent portion hinge 9 connecting the frame 4 and the side plate 2 and the fulcrum of the bent portion hinge 10 connecting the frame 4 and the side plate 3 are the same as the bottom plate 1 and the side plates 2 and 3 described above. The height of the container can be increased up to twice the short side width B of the bottom plate by folding the side plate 3 under the side plate 2 when they are folded by attaching and reversing the relationship with. .

【Example】

 This embodiment will be described in detail by a method adopted in the previous application (application for utility model registration No. 84977 in 1991. FIG. 1 is a perspective view showing the whole one embodiment of the present invention. As shown in FIG. 2, the bottom plate 1 and the side plate 2 are connected in a folding container including side plates 2 and 3 and a bottom plate 1, a frame 4 provided on the upper ends of the side plates, and swing plates 5 and 6 rotatably provided on the frame. The height b of the fulcrum of the lower corner 11 is made higher than the height g of the fulcrum of the lower corner 12 connecting the bottom plate 1 and the side plate 3 by increasing only the thickness j of the side plate when the container is folded. The frame 4 assembly in which the side plate 3 can be folded underneath and the side plates 2 and 3 will be described.The height h of the fulcrum of the long side upper hinge 14 connecting the frame 4 and the side plate 2 is set to the frame 4 and the side. Long side upper hinge 1 connecting the plates 3 By lowering the height i of the fulcrum of the side plate 3, the thickness k of the side plate 3 can be folded into the height i of the upper hinge 13 of the long side. The height of the container can be increased up to twice the width of the bottom by folding and crossing .. This embodiment is also applicable to the conventional folding container as described in the problem to be solved by the present invention. To be done.

[0006]

[Effect of device]

 The present invention can provide a deep foldable container to the market, which was not possible with the conventional foldable container, and has an excellent effect of drastically reducing freight and labor by transporting it in a size according to the contents to be put. Further, there is a space saving effect in a distribution warehouse or the like.
