Description

  The present invention relates to a three-dimensional decorative body formed by assembling sheet materials, which can be used as a three-dimensional pop in advertising and advertising of products.

  At exhibitions and storefronts, fold and assemble sheet materials such as cardboard and plastic sheets, place a three-dimensional pop created by assembling, put a poster etc. on the display surface, or directly print the product name, catchphrase, etc. Advertising and advertising are performed.

  Patent Document 1 discloses a box made by bending a carton blank having a substantially quadrangular prism shape with four side surfaces being wavy curved surfaces in order to enhance the design and give an advertising effect. Similarly, Patent Document 2 discloses a decorative structure manufactured by bending a sheet material, in which four side surfaces are corrugated concave / convex convex. All of these can be effectively used as eye-catching three-dimensional pops that are rich in design. Here, the “wavy curved surface” or “wavy concave surface” and “wavy convex surface” have a curvature only in one direction (this direction is called “wave direction”), and a direction orthogonal to this direction (this direction is “ The term “flat direction” refers to a curved surface having no curvature. In the case of the box and the decorative structure described in Patent Document 1 and Patent Document 2 (hereinafter collectively referred to as “three-dimensional decorative body”), the direction connecting the upper and lower rectangular surfaces is the wave direction, and is perpendicular to the wave direction. Direction, that is, a direction parallel to the upper and lower rectangular surfaces is a flat direction.

JP 2009-067428 A Japanese Unexamined Patent Publication No. 2006-187962

  In the three-dimensional decorative body described in Patent Document 1 and Patent Document 2, all four side surfaces are curved surfaces (waved curved surfaces). This is because when one sheet is bent, the surface adjacent to the wavy curved surface is not a wavy curved surface having the same wave direction and the opposite curvature (referred to as a “complementary curved surface”). It is for not getting. That is, when a certain portion A of a certain surface has an outwardly convex wavy curved surface, a portion B having the same height as a surface adjacent to the surface (a portion at the same position as the portion A in the flat direction) ) Must be a concave wavy curved surface. In addition, although it described as the case where it produces by bending one sheet | seat here, even when it is a case where a separate sheet is assembled in the same shape, when those separate sheets are arranged, it is one sheet without a gap. The same applies to such a case.

  The three-dimensional decorative body having curved surfaces as described above is good to be used in a stand-alone state, but when it is arranged along the wall surface or juxtaposed with another three-dimensional decorative body, a gap is generated. On the other hand, it looks bad.

  The problem to be solved by the present invention is that a single surface is a wavy curved surface, and a surface adjacent to the surface is not a complementary curved surface such as a three-dimensional decorative body described in Patent Document 1, etc. The object of the present invention is to provide a three-dimensional decorative body that can be a straight line on the side facing the side.

The present invention made to solve the above problems is a three-dimensional decorative body formed by bending a single rectangular sheet material,
A front surface that is a wavy concave surface;
Both side surfaces that are connected to both sides in the flat direction of the front surface via arc-shaped fold lines, and the sides facing the fold lines are straight lines;
It has a mountain fold line connecting a point on the side of the side surface and a point on the fold line provided on at least one of the both side surfaces.

  In the three-dimensional decorative body according to the present invention, the front surface is a wavy concave surface, but the side surfaces on both sides are curved in the vicinity of the fold line, but are straight on the opposite side, so the vicinity of the side Then it is close to a plane. Therefore, it can be along the wall surface in the vicinity of the side, or can be juxtaposed with another three-dimensional decorative body.

  However, if the state of the wavy curved surface (complementary curved surface) in the vicinity of the fold line continues, the side surface is in a natural state as described in the section of the prior art, but the side surface is flat in the vicinity of the opposite side. Therefore, an unreasonable stress is generated on the wavy curved surface. Therefore, in the three-dimensional decorative body according to the present invention, by providing the mountain fold line at that portion, the stress is relieved, the arcuate state of the fold line is maintained, and consequently the wavy concave surface on the front is not affected by distortion. I am doing so. Such mountain fold lines may be provided on both side surfaces, but by providing them on at least one side surface, the stress relaxation effect as described above can be obtained.

  As the sheet material, cardboard, cardboard, plastic sheet or the like can be used.

  A plurality of three-dimensional ornaments according to the present invention are arranged in a row in the vertical direction (front wave direction), and both side surfaces are common to the three-dimensional ornaments arranged in the vertical direction, while the front surfaces of the three-dimensional ornaments are mutually connected. It can shift in the lateral direction (flat direction of the front).

  As an example of such a continuously established decorative body, a method for manufacturing a three-dimensional decorative body arranged in two steps will be described below. A cut not extending over the entire width is made in the central lateral direction of one rectangular sheet material. The length of the cut is preferably about 1/3 of the entire width. At the top of the cut, the front is moved to the left to make the width equal to or less than the length of the cut, and at the bottom of the cut, the front is moved to the right to have the same width. Of course, the left and right may be reversed. By assembling such a three-dimensional decorative body on the upper side and the lower side of the cut line of such a sheet material, a continuous establishment decorative body can be produced. Similarly, a three-stage or more consecutively-decorated body decorative body can be produced by shifting the front face up and down.

  According to the three-dimensional decoration according to the present invention, the front surface is a wavy curved surface, and the surface adjacent to the front surface does not have to be a complementary curved surface as in the prior art, and the side facing the boundary side with the wavy curved surface is a straight line. It can be. For this reason, it can arrange neatly even if it makes it line along with a wall surface or other solid decorations.
