Hereinafter, the decorative board according to the best mode of the present invention will be described in detail.
First, the overall structure of the decorative board will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a transparent body made of transparent glass as a transparent material, 10 denotes a figure body on which a pattern is drawn, and 20 denotes a perspective body. The plate glass as a reinforcement body which pinches | interposes the pattern body 10 between the bodies 1 is shown.

  As an example, the glass sheet constituting the transparent body 1 has a thickness a of 8 mm, a width b of 4 mm on the outer surface side thereof, and a plurality of protrusions 2 each having a substantially hemispherical cross section. The outer surface is parallel and corrugated. The thickness a of the transparent body 1 and the width b of the ridge 2 may be appropriately selected according to the object constituted by the decorative board, the design viewed through the transparent body 1, and the like, and there is no limitation.

The pattern body 10 is made of transparent glass as an example, and is formed by a number of thin line-like pixels (marks) 11 drawn at predetermined intervals as shown in a plan view in FIG.
The width c of the thin pixels 11 constituting each symbol is 1/3 of the width b of the protrusion 2 formed on the outer surface of the transparent body 1 (c = b / 3). In FIG. 3, these pixels constitute symbols 12 and 13 that form two large and small circles as a whole, and the pixels constituting these two circles are colored in different colors.

On the other hand, a large number of fine line-like pixels 11 constituting the pattern 12 forming two large and small circles and a large number of fine line-like pixels 11 constituting the pattern 13 are left and right by b / 3 as seen in FIG. They are shifted in the direction (arrangement direction of the protrusions 2 and the pixels 11).
As described above, in the decorative board according to the illustrated embodiment, the symbols 12 and 13 are formed by the pixels 11 having a width 1/3 of the width b of the protrusion 2 formed on the outer surface of the transparent body 1. At the same time, since the pixels 11 of the symbols 12 and 13 are shifted by b / 3, when the viewing angle is changed in the direction in which the ridges 2 are arranged, the symbols changing in three ways can be seen as described later.

  The design body 10 is sandwiched between the fluoroscopic body 1 and the reinforcing body 20 and is detachably held. The design body 10 can be replaced with another design body on which another design is drawn. Since the structure which hold | maintains the pattern body 10 on the opposite side to the outer surface of the fluoroscope 1 so that substitution is possible may be an appropriate | suitable thing, description is abbreviate | omitted for details. Therefore, in the decorative board according to this embodiment, a plurality of types of symbols for replacement are prepared and placed so that the perceived symbols can be changed.

The viewing angle of the decorative board according to the present embodiment configured as described above from the outer surface of the transparent body 1 where the plurality of protrusions 2 are formed to the alignment direction of the protrusions 2 on the outer surface of the transparent body 1. 3 are drawn as shown in FIG. 3 due to the lens effect of the protrusion 2 formed on the outer surface of the fluoroscopic body 1 as shown in FIG. Only the circle 13 on the pattern body 10 can be seen, or the circles 12 and 13 on the pattern body 10 cannot be seen as shown in FIG. 4 (2), or only the circle 12 as shown in FIG. 4 (3). Changes to three states.
Therefore, since the designs having different colors and shapes appear to change, the beauty is improved.

  In the decorative board according to the embodiment described above, the design body 10 includes two types of designs 12 and 13 each having a width of 1/3 of the width b of the protrusion 2 of the transparent body 1 by b / 3. By shifting the protrusion 2 in the width direction, the three patterns shown in (1), (2) and (3) of FIG. 4 can be observed. It is a fraction of the width b of Article 2, and how many types of symbols are formed, how much each symbol is shifted from each other, and what types of symbols are observed when the viewing angle is changed. It may be selected as appropriate. However, if the width b of the ridge 2 is reduced to 1 / n and the value of n is increased and the width of the pixel 11 becomes too small, the pattern that is considered to be unclear is blurred. Needless to say, the value of n should be selected appropriately according to the application.

  Further, in the decorative board according to the above-described embodiment, an example in which two circles of symbols are viewed separately has been described. However, pixels are arranged so that a continuous moving image is represented by a symbol viewed by changing the viewing angle. It is also possible to improve the appeal effect in advertising and the like.

  Moreover, although the example in which the protrusion 2 arranged in parallel only in one direction is formed in the decorative board according to the above-described embodiment, the protrusion 2 formed in parallel on the outer surface of the transparent body 1 is illustrated. By using a structure in which a plurality of groups whose directions are different from the ridges in other parts are combined in a lattice shape, it is possible to observe various patterns that change regardless of the viewing angle. I can do it.

Moreover, in the decorative board of the above-described embodiment, transparent glass is adopted as the transparent material constituting the transparent body. However, the transparent material is not limited to glass, and an appropriate material according to the use of the decorative board, for example, You may employ | adopt the transparent material made from other materials, such as an acrylic board.
Furthermore, as the transparent material, a material colored with a transparent pigment may be used, and in this case, various color changes can be given by utilizing a complementary color relationship with the color of the design. In addition to the above, by making the outer surface of the transparent body 1 into a two-dimensional or three-dimensional spherical surface, it becomes a decorative board that can see designs that change more variously when the viewing angle is changed.

  In the above-described embodiment, the design is drawn on the design body 10, but the design may be omitted by using the design on the surface opposite to the waved outer surface of the transparent body 1. Furthermore, although the reinforcement body 20 is employ | adopted in the decorative board of the said embodiment, when the use of the decorative board by this invention does not require especially intensity | strength, you may omit a reinforcement body.

  Further, in the decorative plate according to the above embodiment, the description has been given of the one in which the cross section of the protrusion formed on the outer surface of the transparent body is a part of a sphere or other curved surface, but the protrusion formed on the outer surface of the transparent body. As long as the outer surface is corrugated, it may be an appropriate curved surface that is not a part of a sphere, or a polygonal cross section such as a hexagon or an octagon.
