Description

[0001]
[Industrial application fields]
The present invention relates to a method for producing a decorative body that three-dimensionally represents a painting or various objects using a piece of paper.
[0002]
[Prior art]
Various methods for three-dimensionally expressing the surface of paintings and various objects with paper pieces have been proposed. For example, glue some sparsely on a piece of paper, paste another piece of paper a little on it, then shift the pieces of paper one after another and glue it to the surface, like this By shifting the piece of paper, a three-dimensional effect is sought due to streaks formed on the surface, unevenness on the surface after coloring, and peeling.
[0003]
In addition, a plurality of horizontally long paper pieces are slightly shifted in the vertical direction and overlapped, and they are sparsely held in the horizontal direction with staples to create a bundle of paper pieces. There are also cases in which this surface is affixed to objects molded in various shapes, and paints with the property of adhering a piece of paper to the surface are used as decorative surfaces, causing irregularities on the produced surface .
[0004]
As another three-dimensional forming method, a piece of paper is cut into a shape to be embodied, and a plurality of three-dimensionally formed pieces are formed by bending the cut piece of paper into a desired shape. In some cases, a plurality of pieces are bonded together by gluing and appearing in a desired concrete object, or the plurality of pieces are continuously combined and glued together to produce a concrete object having a desired shape.
[0005]
As a method for forming a decorative three-dimensional surface using a material other than a piece of paper, a technique called relief (relief) in which a stone material is shaved, the viscosity is increased, or a metal material such as copper or brass is spread is also known.
[0006]
[Problems to be solved by the invention]
In the above-mentioned various conventional ones, the three-dimensional effect is caused by stacking or bending of paper pieces, but in order to produce a three-dimensional effect close to the real thing, it is necessary to form unevenness as close as possible to the real thing, This is a method of expressing a three-dimensional effect in which the unevenness looks close to the real thing.
[0007]
For this reason, in order to obtain a three-dimensional effect that is as close to the real thing as possible, a large amount of work is required, and the protruding portion of the paper piece becomes large, which may be inappropriate as a decorative body. In addition, for example, it is extremely difficult to express a landscape or the like in three dimensions. Furthermore, a plurality of pieces had to be manufactured, which was cumbersome and inefficient.
[0008]
In addition, the relief (relief) technique applies a force to the material and deforms it to emphasize the shadow caused by the light contrast caused by the irradiation and reflection of light, making it too cumbersome to manufacture and cannot be mass-produced.
[0009]
Therefore, the present invention simply puts a curved notch in a piece of paper without substantially deforming the paper material, and easily realizes a three-dimensional effect close to the real thing on the surface surrounded by the curve. The object is to produce a decorative body having a three-dimensional effect, which is inexpensive and can also three-dimensionally represent a picture such as a landscape.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is to fold a sheet of paper into a curved shape so that the indented portion is on the mountain side after a notch with a curve is applied from the back side using a knife. Bend to form a background and a human body, things such as vases, ornaments such as flowers, mountains, etc., in one piece on a slightly uneven surface and stand against a folded paper piece in a box with a light source inside. It is a method for producing a decorative body having a three-dimensional effect, characterized by being provided and irradiating light.
[0011]
[Action]
Since the present invention is configured as described above, when light is applied from a predetermined direction to a paper surface that is bent into a predetermined shape to form an uneven surface, the person who is looking at the bent paper piece is bent. The specific angle part of the piece of paper reflects light and looks very bright, and conversely, the part that is bent in a direction that reflects greatly away from the viewer is dark, contrasting with the intermediate angle. This part looks like various brightness in between. In addition, since the bent paper surface has different curvatures and is continuously formed, a bright portion and a shaded portion are generated by the irradiated light. Nevertheless, the subtle degree of light reflectivity varies from part to part, and it is very three-dimensionally expressed.
[0012]
【Example】
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a three-dimensional representation of a vase pattern 2 on a piece of paper 1 according to the present invention. In the production, as shown in FIG. 2, paper that does not transmit light, such as Kent paper or general Western paper, or paper that has a transparent or colored plastic film adhered to the surface, or various types including silver and gold A notch 4 with an appropriate depth is put into the shape of a vase with a knife 3 from the back side of a piece of paper 1 made of colored colored paper or paper adhered with foil.
[0013]
Next, folds and bent portions are formed on the surface of the other piece of paper as much as possible so that the notch 4 is on the mountain side, that is, the front side of the notch 4 is obtuse on the valley side with the notch as the center. The entire portion of the notch 4 is bent so that there is no gap. At this time, if the notch 4 is put on the front side and bent so that the notch part is on the mountain side, the notch part of the paper surface will spread and the inside of the paper will be exposed, so unless you want a special effect Not appropriate. Also, when the fold is made with a notch as in the above embodiment, the decorative effect of the bent portion on the front side of the paper piece changes depending on the degree of the notch and how the corners of the bent portion are formed. be able to. In other words, if you make a notch relatively deeply and make a strong corner along the contour of the bent part, the light and darkness at that part is clearly expressed, and if you make a corner gently, the lightness and darkness can be changed gently, Various subtle three-dimensional expressions are possible by properly using the degree of bending. For example, when you feel that an object is popping out of the background, you make a strong corner along the contour of the object, and when you express the connecting line part of the curved surface and the curved surface or the curved surface itself, gently fold it. To sing. Therefore, in the above embodiment, in order to give a feeling that the vase 2 has jumped out of the background 5, the contour portion 6 is strongly cornered, and the pattern 7 on the surface of the vase 2 is gently bent to give a texture.
[0014]
The folded paper piece 8 which is bent as described above and has a concavo-convex surface is provided with a light source 10 such as a fluorescent lamp or a colored bulb inside, and the upper surface is formed of a translucent body 11 such as ground glass. The surface is erected on the translucent body 11 on the upper surface of the box 12 made of a non-translucent body, and the light source 10 is turned on with the surroundings made as dark as possible. When viewed from a predetermined position on the front surface of the folded paper piece 8, the entire vase 2 shines, the vase 2 appears to jump out of a dark background, and the surface of the vase 2 can be seen three-dimensionally according to the irregularities on the surface of the vase 2. The bent portion of the pattern 7 formed on the surface also produces various shades along the shape, and a textured pattern appears.
[0015]
As the three-dimensional expression as described above, various things such as a human body, things such as vases, landscapes such as flowers, mountains, and the like are possible. It also Ru effective der using light colored as the light source. For example, as shown in FIG. 3, a cardboard 30 with a colored paint applied on the surface is used, a contour line 32 of the shape of a human body 31 is cut in a curved shape with a knife from the back to the cardboard 30, and the background 33 is made convex. The body part 31 is bent along the contour line 32. Then, since the curvature of each part of the human body is different along the curve of the contour line 32, it is possible to express a human body that appears three-dimensionally with subtle brightness appearing on the human body due to natural light. Furthermore, a soft shadow is formed in the portion of the knife cut along the contour line 34, which is shallower than the portion of the contour line 32, and an attractive, fantasy and elegant texture can be obtained. It is. In addition, the curvature (curvature) becomes large in the portion where the distance between the curves in FIG. 3 is small, and due to the difference in curvature (curvature), the circumference of the waist looks like a low convex shape, and the legs are highly concave. Looks like. In addition, a subtle shade of light appears depending on the depth of the knife cut.
[0016]
Similarly, as shown in FIG. 4, when the contour is bent into the shape of Mt. Fuji and an appropriate wrinkle is formed along the slope of the mountain, when the light source is placed slightly on the back side of the paper and exposed to light, The sky portion 41 is dark and the mountain portion 42 looks bright. On the contrary, when the light source is moved to the front side of the page, the sky portion 41 becomes bright and the mountain portion 42 looks dark. It can be expressed only by movement. Further, at this time, the wrinkle 43 formed along the slope of the mountain can express the unevenness of the mountain surface realistically by forming an appropriate wrinkle on the paper surface with a finger without making a notch in advance from the back surface.
[0017]
On the other hand, when using a piece of paper to which colored paper of various colors including silver and gold is used as a piece of paper, it can be used as it is, but the colored paper on the surface is cut into an appropriate shape, and the cut portion is the surface of the base paper By adopting this state, a three-dimensional object in which appropriate portions are colored can be expressed. Therefore, for example, when the colored paper is left only in the swimsuit portion and the paper piece is bent at the outline of the human body, the scope of application of the present invention becomes very wide, such as representing a woman wearing a colored swimsuit of colored paper in three dimensions.
[0021]
【The invention's effect】
As described above, according to the present invention, a three-dimensional effect close to the real thing can be expressed by a slight unevenness on the surface of one piece of paper, and a painting such as a landscape can be expressed three-dimensionally easily and inexpensively. Can be used in a wide range of fields.
