Description

  The present invention relates to a decorative structure that is placed on the center of a room or on a floor near a wall surface or on a table to decorate the space.

  Many artists and sculptors produce objects made of stone, metal, etc., which are displayed in museums and outdoors during a predetermined exhibition period, or as permanent exhibits indoors or in front of buildings. Installed in parks. Although these are art works on one side, they can be viewed as a decorative structure that decorates the surrounding space from the side using them.

  For example, in a concert, a presentation, or a new product presentation held by a company, a space decoration structure that is installed only for a short period of time is desired instead of such a permanent or semi-permanent installation. Thus, when installing only for a short period of time, rather than a heavy article made of stone, metal, etc., it is desirable that it is manufactured by folding cardboard or a plastic sheet, is lightweight, convenient to handle, and easily discarded.

Various proposals for such an assembly-type space decoration structure have been proposed so far. For example, Patent Document 1 discloses a vertically long decorative structure in which a concavely curved front plate appears after assembly. Patent Document 2 discloses a decorative structure formed by stacking substantially dice-shaped units that are shifted from each other. Furthermore, although not for decorating the space, Patent Document 3 discloses a packaging container having a curved surface and having a three-dimensional design effect.

  Since all of the conventional assembly-type decorative structures are based on the premise that they are manufactured by bending cardboard or the like, they are based on straight lines and have little change.

  The problem to be solved by the present invention is to provide a decorative structure that is easy to assemble and disassemble and that has a highly decorative appearance based on curves and curved surfaces.

The set of decorative structures according to the present invention made to solve the above problems is a set of six-sided decorative structures made of sheet material,
Both are rectangles whose top and bottom are not the same square,
There are two types of sets, a type A in which the long side of the rectangle is concave and a short side is convex, and a type B in which the long side is convex and the short side is concave.
The type A and the type B are the same height,
With short side concave surface of the Type B and the short side convex surface of the type A is in the complementary,
The type A long side concave surface and the short side convex surface, and the type B long side convex surface and the short side concave surface are both complementary .
In the present invention, the upper surface and the bottom surface may be the same square. In this case, the decorative structure according to the present invention is a six-surface decorative structure made of a sheet material, and a pair of opposing side surfaces. Are both convex and the other pair of opposing side surfaces are concave, and the convex and concave surfaces are complementary.

  The convex surface and the concave surface may be curved surfaces, or may be surfaces in which two flat surfaces are connected in a “<” shape.

  The decorative structure according to the present invention may be composed of a plurality of separated sheet materials, but is preferably formed by bending one sheet material.

  Further, an engaging means may be provided in order to connect a plurality of the decorative structures. It is desirable that the engaging means is provided with a protruding piece on one side and a slit for inserting the other on the rectangular sides of the upper surface and the bottom surface. By providing such an engaging means, two (or more) decorative structures can be connected vertically (that is, the upper surface and the bottom surface are in surface contact).

  Since the decorative structure according to the present invention is made of a sheet material, it is easy to assemble and disassemble and is lightweight. Therefore, it is suitable for the purpose of decorating the space by installing it for a short period of time, such as a concert, a presentation, or a new product presentation held by a company. By using cardboard or cardboard as the sheet material, disposal becomes easy and environmentally friendly.

  The thing of the 1st form of the decoration structure which concerns on this invention is shown in FIG. This decorative structure has a curved side surface. As shown in FIG. 1, when the top surface and bottom surface are non-square rectangles, the long side is concave and the short side is convex (this is called A type), and the long side is the convex and short side. A product having a concave surface (referred to as B type) can be produced. As shown in FIG. 6, various types of decorative structures can be manufactured by connecting the A type and the B type vertically and / or horizontally. The decorative structure according to the present invention may have a square top surface and bottom surface, but in that case, there is no distinction between A type and B type. In this case, it becomes easier to connect vertically and horizontally.

  FIG. 2 shows a second embodiment of the decorative structure according to the present invention. This decorative structure has a side surface formed by bending one plane into a “<” shape. When the top and bottom surfaces are rectangular, as shown in FIG. 2, the long side is concave and the short side is convex (A type), and the long side is convex and the short side is concave, as shown in FIG. (B type) can be produced, and various types of decorative structures can be produced by connecting these A type and B type vertically and / or horizontally. FIG. 7 shows an example in the case of connecting up and down. In the case of this form as well, the top surface and the bottom surface can be square as described above.

Various embodiments of the decorative structure according to the present invention will be described with reference to the drawings.
FIG. 3 is a development view of the decorative structure of the first embodiment, in which (a) is an A type and (b) is a B type. Since the decorative structure according to the present invention is a rectangular parallelepiped (hexahedron) as a basic structure, it can be assembled by folding a sheet material such as a piece of cardboard as shown in FIG. In this embodiment, when assembling the decorative structure, the side surface s on the short side of the rectangle is doubled. Since the opposing side faces are convex and concave, the four ridge lines are curved, but in order to bend the sheet material such as cardboard neatly, it is particularly possible to give the curved ridge lines a fold line by pressing. desirable.

  For each decorative structure, a projecting piece 11 is provided on each of the two opposing long sides of the rectangle on the top surface, and a slit 12 is provided on each of the two opposing long sides of the rectangle on the bottom surface. After assembling the decorative structure, the two protruding pieces 11 of one decorative structure are respectively inserted into the two slits 12 of the other decorative structure and shifted laterally, so that the base of the protruding piece 11 is obtained. A certain notch 11a is caught by the main body beside the slit 12, and both decorative structures are fixed.

  FIG. 4 is a development view of another example of the decorative structure of the first embodiment. In this example, one decorative structure is composed of two sheet materials A and B. Further, in the embodiment of FIG. 3, the side surface s on the short side is double and the seam is a ridgeline, but in this embodiment, the side surface on the short side is separated into two surfaces s1 and s2 at the center. The two are joined together by the engaging means. Such a configuration is particularly effective when it is desired to show the ridgeline clearly. In this embodiment, two protruding pieces 21 and two slits 22 for engaging the upper surface and the bottom surface are provided on each long side.

  FIG. 5 is an example of a development view of the decorative structure according to the second embodiment. (a) is of the A type, and (b) is of the B type, and each decorative structure is constituted by two sheet materials as in the example of FIG.

  FIG. 6A shows a state in which a plurality of decorative structures of the first form are stacked up and down. Further, FIG. 6B shows an example of a state where it is connected to the left and right sides and is installed along the wall surface with the pillar 61. By placing such a combination decorative structure on the floor or in front of the wall of an exhibition or the like, the surrounding space can be gorgeously decorated. As shown in FIG. 6 (a), when the stacked state becomes unstable, it is desirable to stabilize by fixing a slightly wider foot 60 to the bottom surface of the lowest decorative structure.

  Similarly, FIG. 7 shows an example of a combined decorative structure in which decorative structures of the second form are stacked.
