<Method for manufacturing ornaments>
Next, a method for manufacturing the decorative article 10 will be described. FIG. 5 is a flow chart showing an example of a method for manufacturing the decorative article 10. As shown in FIG.

(Step S101)
First, the first plate member 11 is prepared. Specifically, the first plate member 11 is formed by cutting a translucent material into a desired shape. Cutting of the translucent material may be performed by a device such as a laser processing machine, or may be performed manually using an acrylic cutter or the like. At this time, the cut translucent material may be chamfered or polished.

(Step S102)
The first concave portion 13 is formed at a predetermined position on the back surface of the first plate-shaped member 11 by etching a pattern obtained by turning over the first pattern. The etching depth may be uniform or may vary depending on the portion of the first pattern. The etching of the first plate member 11 may be performed by a device such as a laser processing machine, or may be performed manually using an acrylic cutter or the like.

(Step S103)
A first painted portion 15 is formed by painting a reversed pattern of the first pattern on the first concave portion 13 formed on the back surface of the first plate member 11 . The painting of the first pattern may be performed by printing the first pattern with a device such as a UV printer, or may be performed manually.

(Step S104)
Next, the second plate member 12 is prepared. Specifically, the second plate member 12 is formed by cutting a translucent material into a desired shape. Cutting of the translucent material may be performed by a device such as a laser processing machine, or may be performed manually using an acrylic cutter or the like. At this time, the cut translucent material may be chamfered or polished.

(Step S105)
A second concave portion 14 is formed at a predetermined position on the surface of the second plate member 12 by etching the first pattern. The etching depth may be uniform or may vary depending on the portion of the first pattern. The etching of the second plate member 12 may be performed by a device such as a laser processing machine, or may be performed manually using an acrylic cutter or the like.

(Step S106)
A second painted portion 16 is formed by painting the first pattern on the second concave portion 14 formed on the back surface of the second plate member 12 . The painting of the first pattern may be performed by printing the first pattern with a device such as a UV printer, or may be performed manually.

(Step S107)
Subsequently, the first plate-like member 11 and the second plate-like member are moved so that the back surface of the first plate-like member 11 and the surface of the second plate-like member 12 are in contact with each other, and the first concave portion 13 and the second concave portion 14 overlap each other. 12 is fixed. The first plate-shaped member 11 and the second plate-shaped member 12 may be bonded together with an adhesive, or their positional relationship may be fixed by a fixture such as a bolt.

(Step S108)
After that, the background portion 17 is formed by forming a pattern obtained by flipping the second pattern at a predetermined position on the back surface of the second plate member 12 . The formation of the background portion 17 may be performed by printing a pattern obtained by flipping the second pattern using a device such as a UV printer, or may be performed by manually painting a pattern obtained by flipping the second pattern. Alternatively, a seal printed with a reversed second pattern may be attached to the back surface of the second plate-like member 12, or another component having the second pattern printed on the front surface may be attached to the second plate member 12. It may be carried out by fixing the two plate members 12 so as to be in contact with the back surface thereof.

(Step S109)
Finally, the light emitting part 18 is fixed to the side surfaces of the first plate member 11 and the second plate member 12 . The light emitting part 18 may be fixed with an adhesive, or may be fixed with a fixture such as a bolt.

The decorative article 10 can be manufactured through the above steps. The order of preparing the first plate-like member 11 and the second plate-like member 12 may be reversed. Also, the second plate member 12 may be formed before the first plate member 11 and the second plate member 12 are fixed.

<Effect of accessories>
As described above, the first plate-like member 11 and the second plate-like member 12 are fixed so that the first concave portion 13 and the second concave portion 14 overlap each other. As a result, the interior of the decorative article 10 (between the first plate-like member 11 and the second plate-like member 12) has the shape of the first pattern surrounded by the first concave portion 13 and the second concave portion 14. A space is formed.

When light enters the decorative article 10, at least part of the entering light is reflected inside the space surrounded by the first concave portion 13 and the second concave portion 14, and the first paint portion 15 or the second paint portion 16 is reflected. through and out of the ornament 10. As a result, the first pattern appears to emit light from the outside.

A conventional decorative article has a pattern-shaped concave portion formed on its surface, and the pattern is made to shine by reflecting light from the concave portion. In contrast, as described above, the decorative article 10 according to the present embodiment forms a space having the shape of the first pattern inside, and reflects light in this space to make the pattern shine. With such a configuration, the decorative article 10 reflects more light at the portion corresponding to the pattern than in the conventional decorative article, so that the luminescence of the pattern (first pattern) can be improved.

As described above, the first pattern of the decorative article 10 has high luminescence, and thus can be visually recognized even when the background portion 17 is provided. In other words, by adopting the configuration of the decorative article 10 according to the present embodiment, the decorative article 10 having the first pattern that looks shiny and the background part 17 drawn as its background can be realized.

Here, the appearance of the ornament 10 will be described in comparison with the neon sign 20. FIG. The neon sign 20 is a signboard including a neon tube having a pattern shape, and functions as a signboard at night or in a dark place by emitting light from the neon tube. FIG. 6 is a perspective view showing an example of the neon sign 20. As shown in FIG. FIG. 7 is a cross-sectional view of the neon sign 20 of FIG. 6 taken along line BB. As shown in FIGS. 6 and 7, the neon sign 20 includes a plate member 21, a neon tube 22, a fixing member 23, and a background portion 24.

The plate-like member 21 is a plate-like member made of metal, plastic, wood, or the like. In the illustrated example, the plate member 21 is rectangular.

The neon tube 22 has the shape of the third pattern. In the illustrated example, the third pattern is a substantially rectangular contour line and characters "engraved character" surrounded by the contour line. Although not shown, the neon tube 22 is connected to a power source and emits light by power supplied from the power source.

The fixing member 23 is a linear member that fixes the neon tube 22 at a predetermined position on the plate member 21 . The fixing member 23 extends vertically from the plate member 21 and has one end fixed to the plate member 21 and the other end fixed to the neon tube 22 .

The background portion 24 is the portion of the fourth pattern drawn on the surface of the plate-like member 21 . In the illustrated example, the fourth picture is a substantially rectangular painted portion and characters "engraved characters" surrounded by the painted portion.

In this neon sign 20, the neon tube 22 emits light so that the third pattern appears to shine. Further, when the neon tube 22 emits light, the light from the neon tube 22 is reflected by the plate-shaped member 21, and the reflected light brightens the surroundings of the neon tube 22, giving the neon sign 20 a unique vague feeling (emission of neon). The area around the tube 22 dimly brightens with light of the same color as that of the neon tube 22). In particular, when the surface of the plate-shaped member 21 is formed with the background portion 24 of the fourth pattern drawn so as to cover the third pattern when the neon sign 20 is viewed from the front, the vague feeling is enhanced. .

Thus, the unique vagueness of the neon sign 20 is due to the presence of a gap between the neon tube 22 (third pattern) that emits light and the plate member 21 on which the background portion 24 (fourth pattern) is formed. (See FIG. 7).

By the way, the decorative article 10 according to the present embodiment has a second plate-like shape in which a space (first pattern) between the first concave portion 13 and the second concave portion 14 that emit light and a background portion 17 (second pattern) are formed. A gap exists between the member 12 and (see FIG. 4). That is, the decorative article 10 has a structure similar to that of the neon sign 20 . Therefore, the decorative article 10 can reproduce the unique vagueness of the neon sign 20. - 特許庁In particular, as shown in FIG. 1, when the ornament 10 is viewed from the front, by drawing the second pattern (forming the background portion 17) so as to cover the first pattern (forming the background portion 17), the vagueness of the appearance is enhanced. be able to.

In this embodiment, the decorative article 10 can also be configured without the first paint part 15 or the second paint part 16 . In this case, the coloring of the first pattern becomes weak. Also, the decorative article 10 may be configured without the first paint part 15 and the second paint part 16 . In this case, the first pattern shines white. Also, the decorative article 10 can be configured without the background portion 17 . In this case, the vague feeling of the neon sign 20 is weakened. Also, the decorative article 10 may be configured without the light emitting section 18 . In this case, the first pattern emits light due to light incident from the external environment.
