DETAILED DESCRIPTION OF THE INVENTION
A three-dimensional decorative board according to an example of the embodiment of the present invention will be described with reference to FIGS. 1 and 2. This three-dimensional decorative plate is composed of two cardboard development plates 10 that form square column boxes 19 having square sections on both sides by four circumferential plates 10 a to 10 d having the same width through the folding line 12, and 4 through the folding line 22. A single cardboard developing plate 20 that forms a square column box 29 having the same shape in the middle with the peripheral plates 20a to 20d, and the opposite corner portions of the square column box 19 on the both sides and the square column box 29 in the middle are crossed. A thick card connecting plate 30 and a cardboard locking plate 40 for locking the connecting plate are manufactured.
[0006]
Adhering pieces 11 are connected to side edge portions on both sides of the development plate 10 via a fold line 11a. A string hole 15 is formed in a lower portion of the middle folding line 12.
[0007]
A sticking piece 21 is continuously provided on one side edge portion of the development plate 20 via a fold line 21a. The fold line 22 on both sides of the fold line 22 in the middle is provided with a slit 23 cut from the lower edge so as to be inserted into a slit 33 (described later) of the connecting plate 30 and an engaging piece 36 (described later). A slit 24 for engaging is formed.
[0008]
The connecting plate 30 is formed with a folding line 31 for folding at the middle position in the lateral direction, and a slit 32 for engaging a later-described engaging piece 44 is formed at the center thereof. Insertion slits 33 cut from the upper edge are formed at both side positions corresponding to half of the distance between the opposing corner portions of the prismatic box 19 with respect to the middle folding line 22, and the slit 33 is formed at the upper end thereof. The engaging piece 36 that communicates with is formed by a cut. Further, string holes 39 are provided in the upper portions on both sides of the connecting plate 30 outside the slit 33.
[0009]
The development plates 10 and 20, the connecting plate 30, and the locking plate 40 have the same vertical width. The lateral width W1 of the connecting plate 30 is set to be three times the distance between the opposing corner portions of the prism column boxes 19 and 29 having the same shape. The lateral width W2 of the locking plate 40 is set to half the distance between the above-mentioned opposing corner portions. The slit 23 of the developing plate 20 is cut so as to reach the half vertical position, and the slit 33 of the connecting plate 30 similarly reaches the half vertical position through the engaging piece 36.
[0010]
Engaging pieces 44 extend from one side edge of the locking plate 40, and slit-like engaging grooves 45 are formed at the upper and lower bases thereof. Furthermore, the sticking piece 42 is continuously provided through the fold line 41 on the other side edge.
[0011]
At the time of assembly, the sticking piece 21 of the developing plate 20 is stuck to the side portion of the side plate 20a at the opposite end, and is bent at each folding line 22 to form a square prism box 29 in the middle. The sticking piece 42 is bent at a fold line 41 and attached to the side portion of the side plate 20 d adjacent to the sticking piece 21. Next, the slits 33 on both sides of the connecting plate 30 are inserted into the slits 23 on both sides of the prismatic box 29 from below. At that time, the engaging piece 36 of the connecting plate 30 is engaged with the slit 24 to restrain the insertion position in the vertical direction. The sticking pieces 38 on both sides are raised at the fold line 37 and attached to the side end portions of the side plate 20c.
[0012]
Subsequently, the two developing plates 10 are bent at each fold line 12 so that the corner portions of the prism box 29 are adjacent to each other to form the prism column box 19, and the sticking pieces 11 on both sides are folded at the fold line 11a. Bend and attach to both front and back surfaces of the connecting plate 30. By engaging the engaging piece 44 of the locking plate 40 into the slit 32 and engaging the upper and lower engaging grooves 45 with the upper and lower ends of the slit 32, the bending of the connecting plate 30 at the folding line 31 is restrained.
[0013]
As shown in FIG. 2, when the string 49 is passed through the string hole 39 and hung with the caulking pieces 49 a attached to the string holes 15 on both sides and is put in tension by its own weight, the corner portion on the outside of the prismatic box 19 is connected. A rectangular columnar shape is ensured by contacting both side edges of the plate 30.
[0014]
In the retracted state, the side plates 10a to 10d of the prism box 19 on both sides are folded so as to contact each other, and the folding plate 44 is removed and the folding plate 31 is folded at the middle folding line 31 of the connecting plate 30 and the side plates 20a to 20d of the prism box 29. Fold them so that they face each other and fold the whole flat.
[0015]
Each of the side plates 10a to 10d and 20a to 20d can be colored with a color suitable for the situation in the store, or can be provided with a pattern. In addition, the middle prism box and the prism boxes on both sides can be rhombus, and various modifications are possible such that only the prism boxes on both sides are rhombus. The locking plate protruding from the corner portion of the middle prismatic box can be connected to the developing plate.
[0016]
