Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to an assembly box that is easy to assemble.

(Prior Art) Conventionally, assembly boxes made of paper, cardboard, or plastic sheets are known. These assembling boxes are constructed by standing up side plates connected to the edge of the bottom plate, overlapping the connecting plate connected to one side plate with the other side plate at the adjacent parts of the side plates, and fixing the overlapping part with rivets or paper binding. It was fixed with a metal needle.

(Problem to be solved by the invention) An assembly box whose overlapping parts are fixed with rivets requires a large number of holes to be made in advance for the rivets to pass through, which poses the problem of requiring a lot of pre-processing. At the same time, since each hole is fixed with a rivet, there is a problem in that the assembly work is complicated.

Metal rivets and plastic rivets have been used, but metal rivets have a problem with rusting, and plastic rivets do not cause rust, but due to their large head structure, they are not suitable for boxes. There was a problem that protrusions were formed on the inside and outside of the tube.

Assembling boxes in which the overlapping parts are fixed with metal needles using a paper binding device have the problem that the assembly work is complicated and the metal needles rust.

In addition, the side plates were fixed with tacks or paper binders, which made them difficult to use as boxes.

(Means for Solving the Problem) Therefore, the present invention is to form a cut groove in the overlapping portion of the side plate and the connecting plate in the adjacent portions of the side plates, and to insert and latch a latching clip into the cut groove. In this way, we obtained an assembly box that not only facilitates assembly, but also allows the connection plate to have multiple cut grooves to change the upright angle of the side plates.

That is, in the assembly box of this invention, the side plates that are connected to the edge of the bottom plate in a flexible manner are upright, and the connecting plate that is connected to one side plate is overlapped with the other side plate at the adjacent part of the side plates. In the side plate, the overlapping portion matches the notch grooves provided in the side plate and the connecting plate, and a latching clip is inserted and latched into the notch groove, and the side plate is connected to the edge of the bottom plate. A feature is that there are multiple cut grooves in the connecting pieces connected to one side plate.

The sheets constituting the bottom plate, side plates, and connecting plates are a low-foam plastic sheet, a paper sheet impregnated with plastic, or a cardboard sheet made of paper or plastic, but a metal sheet that prevents rusting may also be used. can.

Further, although the bottom plate is generally square, it can also be triangular or a polygon with more than five sides. Side plates connected to the edge of such a bottom plate are often raised at right angles, but they do not necessarily need to be set at right angles, and any side plate may be set up at an angle greater than a right angle to the bottom plate. can. Since this rising angle is determined by the position of the cut groove in the connecting plate connected to the side plate, we created cut grooves in multiple locations on the connecting plate to make it possible to change the rising angle of the side plate. .

The retaining clip is made of molded plastic and has a structure in which retaining flanges are provided at both ends of the insertion portion, which has a width equal to the width of the cut groove and a thickness equal to the overlapping thickness of the side plate and the connecting plate. is used, but it may also be made of metal and plated to prevent rusting. In addition to making the two hanging flange disks of the same size, the size and shape of the two latching flange may be changed in consideration of insertion into the cut groove, or one of the latching flange may be made into an L-shaped cross section. It is also possible to stack multiple layers.

(Function) According to the assembly box of this invention, the connecting plate and the side plate are overlapped at the adjacent portions of the side plates so that their notch grooves match, and the clips are attached to the matched notch grooves. Since it is assembled by inserting and latching, it can be easily assembled and disassembled. Further, since it is sufficient to simply provide the cut grooves in the sheets constituting the side plates, etc., the required pre-processing can be reduced. Furthermore, by selecting the cut groove of the connecting plate that matches the cut groove of the side plate, it is possible to change the upright angle of the side plate.

(Example) An example of this invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a bottom plate, 2 is a side plate, and 3 and 3a are connecting plates, which are made of a single low-foam plastic sheet, and the side plate 2 is bent at the edge of the bottom plate 1. The connecting plates 3 and 3a are connected to the side edge of the side plate 2 so as to be flexible. Among the side plates 2, 2, in FIG. 1, cut grooves 4, 4 are formed in the vertical direction on both sides of the upper edges of the two side plates 2, 2 facing each other in the front and back, and the connecting plates 3, 3a has a pentagonal shape, and when the left and right opposing side plates 2, 2 are made perpendicular to the bottom plate 1, cut grooves 5a, which match the cut grooves 4, 4;
5a, and the connecting plates 3a, 3a are provided with
Furthermore, with the side plate 2 tilted as shown in Figure 1,
Cut grooves 5, 5 are provided that match the cut grooves 4, 4.

At the overlapping portions of the side plate 2 and the connecting plates 3, 3a, a clip 6 is inserted and hooked into the mutually aligned cut grooves 4 and 5 or into the cut grooves 4 and 5a, thereby enabling the overlapping to be fixed.

The latching clip 6 is molded from plastic, and as shown in FIGS. 3 and 4, it is composed of an insertion portion 7 and latching flanges 8 at both ends thereof.
The insertion portion 7 has a width and height similar to the cut grooves 4 and 5.
In addition, the thickness is made equal to the overlapping thickness of the side plate 2 and the connecting plate 3, and when the insertion part 7 is inserted into the matching cut grooves 4 and 5, the latching collars 8 and 8 are made equal to each other.
The overlapping side plates 2 and connecting plate 3 are sandwiched and fixed.

The assembly box of the above embodiment can be used for any purpose, for example, as a returnable box or a parts box.

When constructing an assembly box, each side plate 2, 2 is attached to the bottom plate 1.
At the same time as standing up on the edge of the side plates 2, 2, a connecting plate 3, which is connected to one side plate, is connected to the side plate 2,
3a to the other side plate 2, align the cut grooves 4, 5, 5a formed in the side plate 2 and the connecting plates 3, 3a, and insert and latch the clip 6 into the corresponding part to complete the assembly. Since it is complete, it can be assembled very easily and automatic assembly is also possible. Cut groove 4,
It can be disassembled by removing the retaining clips 6 inserted into and retained by 5 and 5a, and it is easy to disassemble, and the side plates 2 and the like can be spread out to form a flat sheet.

In addition, the connecting plate 3a has two cut grooves 5, 5a.
, it is possible to change the angle at which the side plate 2 is raised. In addition, in the embodiment, the cut grooves 5, 5a
Although it is assumed that there are two locations, it is also possible to provide three or more locations so that the angle at which the side plate is raised can be further finely changed.

Further, the pre-processing required for assembly is only to form the cut grooves 4, 5, 5a in the side plates 2 and the connecting plates 3, 3a, so that the pre-processing can be reduced.

On the other hand, the member for fixing the assembled state may be the above-mentioned retaining clip 6, and can be made of plastic or metal that has been plated to prevent rusting, so that rust can be avoided even after long-term use. I can do it. Furthermore, since the latching clip 6 is composed of the insertion portion 7 and the latching collar 8, and the latching collar 8 can be formed into a thin plate, it is possible to avoid the formation of protrusions inside and outside the box. Also, the latching clip 6 is attached to the latching collar 8.
Since this prevents the side plate from coming off against your will, the side plate can be reliably maintained at a predetermined upright angle.

Incidentally, this latching clip 6 can be made into various shapes and have additional functions. For example, as shown in FIG.
A vertically extending portion 8a is provided at the upper portion of the latch 8 (on the left side in the figure), and a horizontally extending portion 8b is provided on the upper portion of the latch collar 8 (on the right side in the figure) which should be inside. When such a latching clip 8 is used, it is possible to stack a plurality of assembly boxes in multiple stages via the vertically extending portion 8a and horizontally extending portion 8b, as shown in FIG.

Furthermore, as shown in FIGS. 7 and 8, by providing a vertically extending portion 8c at the lower part of one of the two locking collars 8, 8, as shown in FIG. As shown in , when inserting the insertion part 7 into the cut groove,
The overlapping side plate 2 and connecting plate 3 can be smoothly fitted between the locking collars 8, 8 using the vertically extending portion 8c as a guide.

(Effects of the invention) As explained above, according to this invention, the cut grooves provided on the side plate and the connecting plate are aligned, and the latching clip is inserted and latched into the corresponding parts, making assembly and disassembly easier. This is an effect that can be provided by an easy-to-assemble box.
Further, since the latching collar of the latching clip only holds the side plates and the connecting plate, it can be made into a thin plate shape, and has the effect of not forming any protrusions inside or outside the box. Furthermore, all the members can be made of plastic, which has the effect of providing an assembly box that does not cause rust, and even if metal members are used, rust can be prevented structurally by plating or the like.

In particular, the connecting plate connected to one side plate has multiple cut grooves, so the angle at which the side plate is raised can be changed as appropriate, and the angle can be reliably maintained using the latching clips. This has the effect of improving usability and making it a versatile assembly box.

Also, if the assembled box of this invention is used as a returnable box, the latching clips should be removed when returning the box.
It can be transported in the form of a flat sheet, which has the effect of increasing the efficiency of logistics.
