The present invention relates to a decorative item and a method for manufacturing the decorative item, and more particularly to a decorative item using light and a method for manufacturing the decorative item.
Hereinafter, the decorative products 1b and 1c according to the embodiment of the present invention will be described.
In the embodiment described below, the side where the lacquer portion 5b and the top clear portion 5c are located (upper side in FIG. 2) is the surface side of the decorative items 1b and 1c and the side where the background coating portion 3a is located (lower in FIG. 2). The side) will be described as the back side of the decorative items 1b and 1c.
Further, the embodiments described below are merely examples for facilitating the understanding of the present invention, and do not limit the present invention. That is, the shapes, dimensions, arrangements, etc. of the members described below can be changed and improved without departing from the gist of the present invention, and it goes without saying that the present invention includes equivalents thereof.

(About the composition of decorations)
First, the configuration of the decorative item 1b according to the present embodiment will be described with reference to FIGS. 1 and 2. It should be noted that FIG. 1 is a view showing the surface of the decorative item 1b according to the embodiment of the present invention, and is a plan view showing a state in which light is not irradiated, and FIG. 2 shows a cross section II-II of FIG. It is a cross-sectional view.
The decorative item 1b according to the present embodiment is decorated with a goldfish as shown in FIG. 1 by the lacquer part 5b described later. The goldfish-decorated lacquer work portion 5b is formed so as to protrude from the background coating portion 3a as shown in FIG. 3 and described later by the light emitted from the LED 8 described later on the back surface side.

The decorative product 1b according to the present embodiment has a laminated structure, and as shown in FIG. 2 in detail, the transparent base material 2x, the back surface layer 23 coated on the back surface of the transparent base material 2x, and the transparent base material. It is mainly composed of a surface layer 25 coated on a 2x surface.

The transparent base material 2x is a plate material having a thickness of about 3 mm made of translucent polycarbonate, and is a base member to be coated on the background coating portion 3a and to be adhered to the reflection promoting layer 5d described later. .. In particular, if the transparent base material 2x is made too thin, the rigidity becomes low. Then, when the transparent base material 2x is bent, it is necessary to suppress the occurrence of cracks in the background coating portion 3a and the lacquer portion 5b, which will be described later. Therefore, the transparent base material 2x preferably has a thickness of about 3 mm or more.
On the other hand, if the transparent base material 2x is adhered or fixed to another member so as to limit the deformation of the transparent base material 2x so as not to affect the background coating portion 3a and the lacquer work portion 5b, the transparent base material 2x is used. It is also possible to thin the material 2x into a film.

The transparent base material 2x is not limited to one made of polycarbonate as long as it has translucency. For example, the transparent base material 2x may be a resin film such as acrylic, AES (Acrylonitrile Ethylene Styrene), PVC (Poly Vinyl Chloride), or a glass plate.

The back surface layer 23 is located at the same height as the colored background coating portion 3a applied to the back surface side of the transparent base material 2x and the background coating portion 3a, and is a space in which the background coating portion 3a is not applied. It is composed of an optical unit 2y and. The background coating portion 3a corresponds to the first decorative portion according to the present invention, is a portion painted with a colored paint, and has a film thickness of about 1 mm or less.

The surface layer 25 is formed on the surface side of the light-shielding / reflective layer 5a, the reflection-promoting layer 5d adhered to the surface side of the transparent base material 2x, the light-shielding / reflective layer 5a adhered to the surface side of the reflection-promoting layer 5d, and the light-shielding / reflective layer 5a. It is composed of a lacquer portion 5b, a light-shielding / reflective layer 5a, and a top clear portion 5c coated so as to cover the lacquer portion 5b. Here, the light-shielding / reflective layer 5a and the lacquer portion 5b are portions corresponding to the second decorative portion according to the present invention.

The light-shielding / reflective layer 5a is a painted portion coated with white urethane coating or the like having light-shielding property and light-reflecting property, and among the light emitted to the surface side of the decorative item 1b through the light guide section 2y. This is for blocking and reflecting the light passing through the lacquer portion 5b. The light-shielding / reflective layer 5a has a light-shielding property, and by blocking the light directed to the lacquer work portion 5b, the contrast with respect to the light passing through the emission part 5x described later around the lacquer work part 5b can be enhanced, and the lacquer work part can be enhanced. It is possible to make 5b stand out.
Further, the light-shielding / reflective layer 5a has light reflectivity, and by reflecting the light toward the lacquer portion 5b, the amount of light passing through the emission portion 5x described later around the lacquer portion 5b can be increased. It is possible to make the lacquer work part 5b stand out.

The light-shielding / reflective layer 5a is formed so as to cover the light guide portion 2y from the surface side which is the exposed surface side of the surface layer 25 which is not the transparent base material 2x side. Strictly speaking, the light-shielding / reflective layer 5a is formed so as to protrude outward from the boundary 10c (which is a closed space) in the direction perpendicular to the front and back directions of the background coating portion 3a and the light guide portion 2y. In other words, the boundary 10c between the background coating portion 3a and the light guide portion 2y is located inside the outer periphery of the light-shielding / reflective layer 5a (lacquer portion 5b) in the front-back direction of the decorative item 1b so that the light-shielding / reflective layer 5a It is formed at a position that overlaps with.

In the present embodiment, the lacquer portion 5b forms a decoration for a goldfish, and is a portion coated on the light-shielding / reflective layer 5a, for example, a natural lacquer portion is lacquered with gold leaf or the like. , Has a film thickness of about 1 mm or less.
The top clear portion 5c is made of a translucent resin material containing, for example, a UV paint. The top clear portion 5c covers and protects surfaces other than the peripheral surfaces of the light-shielding / reflective layer 5a and the reflection promoting layer 5d and the bottom surface of the lacquer portion 5b, and smoothes the surface. The portion of the top clear portion 5c that does not intersect the light-shielding / reflecting layer 5a, the lacquer portion 5b, and the reflection promoting layer 5d in the front-back direction functions as a emitting portion 5x that emits light passing through the light guide portion 2y to the surface side. In this way, by irradiating ultraviolet rays with the UV paint, the drying time can be reduced and thick coating can be performed. Therefore, the number of coatings of the top clear portion 5c can be reduced to reduce the manufacturing man-hours. Further, since the UV coating material can shorten the drying time by irradiating with ultraviolet rays, it is possible to suppress the occurrence of unevenness in the thickness of the top clear portion 5c, and it is possible to form these thinly.

The reflection promoting layer 5d is a layer for diffusely reflecting light, and the back surface side thereof is surface-treated in a satin finish. In this way, the reflection promoting layer 5d not only blocks light below the lacquer work portion 5b, but also reflects light to increase the light emitted from the emission unit 5x around the lacquer work portion 5b.
It should be noted that the reflection promoting layer 5d may be provided with a translucent material, and the reflection promoting layer 5d may be provided on the back surface side of the transparent base material 2x and facing the light guide portion 2y. .. By providing the reflection promoting layer 5d on the back surface side of the transparent base material 2x in this way, the amount of light emitted from the emitting portion 5x can be increased.

Then, in order to irradiate the portion of the decorative product 1b facing the back surface of the background coating portion 3a with light so that the lacquer portion 5b emerges from the background coating portion 3a via the light source portion 2y, the transparent base material 2x, and the like. A plurality of LEDs 8 as a light source according to the present invention are attached. The LED 8 according to the present embodiment is a member arranged in a layered manner extending in parallel with the transparent base material 2x and the background coating portion 3a.
In FIG. 2, a space is formed between the background coating portion 3a and the LED 8. Whether to form this space or not to form a space by directly contacting the background coating portion 3a and the LED 8 depends on the method of applying the background coating portion 3a in the decorative item 1b, the method of attaching the LED 8, and the heat generation of the LED 8. It can be arbitrarily changed according to the amount, the heat resistance of the background coating portion 3a, and the like.

Further, the light source may be any member as long as it is a member that emits light, and is not limited to the LEDs 8 arranged in layers. As the light source, for example, the light emitted from an arbitrary position, which is located at a position facing the transparent base material 2x and is not formed in a layer shape extending parallel to the transparent base material 2x and the background coating portion 3a, is used. The transparent base material 2x may be irradiated through a light guide member made of a reflective material such as a mirror and a translucent material, and further via a light guide portion 2y. Furthermore, the present invention is not limited to LEDs, and may be light bulbs, liquid crystals, LDs (Laser Diodes), organic EL (Organic Electro Luminescence) elements, and other solid-state light emitting elements.

Then, while supplying electric power to the LED 8, a control unit C for turning on / off the light emission of the LED 8 and selectively enabling only a part of the LED 8 to emit light, which will be described in detail later, is connected to the LED 8. Has been done.

(About the decoration effect of decorations)
Under the control of the control unit C, the light emitted from the LED 8 passes through the transparent base material 2x in the gap between the light guide unit 2y and the background coating unit 3a and the reflection promoting layer 5d, and further passes through the background coating unit 3a and the reflection promoting layer. It is discharged from the discharge portion 5x to the surface side of the decorative item 1b through the gap between the 5d and the 5d. As shown in FIG. 3, the light emitted from the emission portion 5x brightens the surroundings so as to make the lacquer portion 5b stand out.

In particular, as described above, the boundary 10c between the background coating portion 3a and the light guide portion 2y is formed inside the outer periphery of the light-shielding / reflective layer 5a (lacquer portion 5b). Therefore, even when no light is emitted from the LED 8, the gap between the background coating portion 3a and the lacquer portion 5b (light-shielding / reflection layer 5a) (in other words, the background coating portion 3a and the light guide portion 2y) The boundary 10c) can be made difficult to see from the surface side, and the appearance can be improved. Further, when the light is emitted from the LED 8, it is possible to suppress the direct light from entering the user's eyes and impart a high design effect as indirect lighting.

Further, when the thickness of the background coating portion 3a and the lacquer portion 5b has a predetermined relationship, the background coating is performed by the light diffraction effect even if the emission portion 5x and the LED 8 are not linearly communicated with each other. Light can be emitted to the emitting portion 5x from between the portion 3a and the lacquer portion 5b (light-shielding / reflecting layer 5a). That is, when the user looks at the surface of the surface layer 25 of the decorative item 1b from an angle, the gap between the background coating portion 3a and the lacquer portion 5b (light-shielding / reflective layer 5a) cannot be seen at all. Even with the configuration, light can be emitted from the emission unit 5x.

(About the manufacturing method of decorative products)
As a method for producing the above-mentioned decorative item 1b, first, a transparent base material 2x is prepared. The background coating portion 3a is applied to the back surface side of the prepared transparent base material 2x. At this time, the back surface layer 23 is formed by applying the background coating portion 3a to the transparent base material 2x in a state where the portion to be the light guide portion 2y is masked.
Then, the reflection promoting layer 5d is adhered to the surface side of the transparent base material 2x, and the light-shielding / reflective layer 5a and the lacquer portion 5b are applied.
Specifically, after the reflection promoting layer 5d is adhered to the transparent base material 2x, the light-shielding / reflecting layer 5a and the lacquer portion 5b are sequentially applied to the surface of the reflection promoting layer 5d in a state where the portion to be the emission portion 5x is masked. Further, the top clear portion 5c is applied so as to cover the transparent base material 2x and the lacquer portion 5b from the surface side to form the surface layer 25. When the reflection promoting layer 5d is adhered to the transparent base material 2x and the light shielding / reflecting layer 5a and the lacquer portion 5b are applied to the reflection promoting layer 5d, these are the boundaries 10c between the background coating portion 3a and the light guide portion 2y. Make sure that it overlaps at least a part of the front and back sides.
In this way, the decorative item 1b capable of emitting light from a part around the lacquer part 5b can be manufactured.

<First modification>
Next, the decorative item 1c according to the first modification will be described with reference to FIGS. 4 to 6. Note that FIG. 4 is a view showing the surface of the decorative product 1c according to the first modification, a plan view showing a state in which light is not irradiated, and FIG. 5 is a cross-sectional view showing a VV cross section of FIG. FIG. 6 is a view corresponding to FIG. 4, and is a plan view showing a state in which light is irradiated.

As one of the differences between the decorative product 1c and the decorative product 1b, the decorative product 1c is different from the decorative product 1b according to the above embodiment, and as shown in FIG. 5, the surface layer 35 has a light-shielding / reflective layer 5a and reflection. It does not have a promotion layer 5d.
In the decorative product 1b according to the above embodiment, a configuration in which a light-shielding / reflective layer 5a is provided on the back surface side of the lacquer work portion 5b has been described. Since the light-shielding / reflective layer 5a has a light-shielding property, it is possible to suppress the emission of light from the lacquer portion 5b to the surface side, and the contrast between the light and darkness with the emitted light 9 emitted from the emission portion 5x is emphasized. Therefore, the design effect of the decorative item 1b can be enhanced. Further, since the light-shielding / reflecting layer 5a has light reflectivity, the amount of emitted light 9 emitted from the emitting portion 5x can be increased.
However, in order to obtain the effect of making the lacquer portion 5b stand out, the lacquer portion 5b may have a lower translucency than the top clear portion 5c constituting the emission portion 5x according to the above embodiment. Further, if sufficient light is emitted from the emitting unit 5x, the light-shielding / reflecting layer 5a having light reflectivity has an arbitrary configuration.

Further, if the reflection promoting layer 5d is provided, the amount of emitted light 9 emitted from the emitting portion 5x can be increased, which is preferable, but this is also an arbitrary configuration. For example, when a sufficient amount of light is obtained without the reflection promoting layer 5d, the step of adhering the reflection promoting layer 5d to the transparent base material 2x can be eliminated by excluding the reflection promoting layer 5d from the calibration. , The production of the decorative product 1c can be facilitated.

Further, in the decorative product 1c, unlike the decorative product 1b according to the above embodiment, the top clear portion 5c is not formed in the surface layer 35. It is desirable to provide the top clear portion 5c on the surface side of the decorative product 1b according to the above embodiment because the lacquer portion 5b can be protected and the surface of the decorative product 1b can be smoothed.
However, when the importance of smoothing the surface side of the decorative item 1b is low and the need for protection of the lacquer portion 5b is low, for example, by providing a cover member (not shown) on the surface side, the decorative item 1c As described above, the top clear portion 5c may not be provided. As described above, if the decorative product 1c does not have the top clear portion 5c, the man-hours for applying the top clear portion 5c to the transparent base material 2x can be reduced, and the space around the lacquer portion 5b as a discharge portion can be reduced. Since light can be emitted directly, the design effect can be enhanced.

Further, the back surface layer 33 laminated on the transparent base material 2x according to the decorative product 1c is different from the back surface layer 23 of the decorative product 1b according to the above embodiment. Specifically, the boundary 10d of the background coating portion 3b and the light guide portion 2y on the left side in FIG. 5 in the direction perpendicular to the front and back directions is outside so as to form a gap G between the background coating portion 3b and the lacquer portion 5b in the surface direction. It is in.

By forming the back surface layer 33 in this way, the light emitted from the LED 8 can be linearly emitted only a part through the gap G between the background coating portion 3b and the lacquer portion 5b. Therefore, as shown in FIG. 6, the amount of light emitted from only a part of the emitted light 9a on the surface side of the gap G can be increased, and the design effect can be enhanced.

Further, the boundary 10e in the direction perpendicular to the front and back directions of the background coating portion 3c and the light guide portion 2y on the right side in FIG. 5 is at a position that coincides with the outer circumference of the lacquer portion 5b in the front and back directions. Even in such a positional relationship, the lacquer portion 5b limits at least a part of the linear emission of the light emitted from the LED 8. Therefore, even in such a case, the decorative item 1c can obtain a design effect as indirect lighting.

That is, if the lacquer portion 5b is formed at a position where it overlaps at least a part of the light guide portion 2y in the front-back direction, the amount of light emitted from the LED 8 and the location where the light is emitted can be limited. Further, a part of the lacquer portion 5b is formed at a position where it overlaps at least a part of the boundary 10e between the background coating portion 3c and the light guide portion 2y in the front and back directions, thereby exhibiting a design effect as indirect lighting. be able to.
In other words, the decorative product according to the present invention only needs to be able to exert a design effect as indirect lighting in at least a part thereof, and the boundary 10c is formed inside the surface direction over the entire circumference of the lacquer portion 5b. You don't have to be.

(About light production)
Next, with reference to FIG. 7, the light effect of the decorative item 1b will be described. Regarding the light effect described below, the same effect can be achieved with the decorative item 1c. Here, FIG. 7 is a plan view showing the light effect of the decorative item 1b.
The decorative item 1b is designed by simply irradiating the periphery of the lacquer part 5b to make the lacquer part 5b appear to stand out from the background coating part 3a, and by controlling the control unit C to produce various light effects. The effect may be enhanced.

For example, the control unit C controls the emission and emission of the light by the LED 8 to be gradually repeated at predetermined intervals so that the emitted light 9 shown in FIG. 3 is extinguished and turned on like the light of a firefly. It may be. Further, as shown in FIG. 7, the control unit C emits light only from a part of the plurality of arranged LEDs 8 so as to sequentially turn on the emitted light 9b at a plurality of locally scattered locations. It may be controlled to. Further, the control unit C sequentially turns on and extinguishes the adjacent LEDs 8 among the plurality of arranged LEDs 8, and whether the emitted light 9b is continuously moving so as to connect the plurality of locally scattered locations. It is also possible to make it look like.
It should be noted that the decorative item 1b does not require the above-mentioned effect, and when only the on / off of the light emission is operated, it is not necessary to include the control unit C.

<Second modification>
Next, the decorative item 1d according to the second modification will be described with reference to FIG. Here, FIG. 8 is a view showing the surface of the decorative item 1d according to the second modification, and is a plan view showing a state in which light is not irradiated.
In the decorative products 1b and 1c according to the above embodiment, an example in which at least a part of the lacquer portion 5b is formed at a position where at least a part of the boundaries 10c and 10e overlap in the front and back directions has been described. With such a configuration, at least a part of the lacquer work portion 5b can be indirectly illuminated by the emitted light 9, so that the design effect can be enhanced. However, the invention of the present application is not limited to such a form.

The decorative item 1d according to the second modification is, for example, about 1 mm to 5 mm between the boundary perpendicular to the front and back directions of the background coating portion 3b and the light guide portion 2y and the edge in the surface direction of the lacquer portion 5b. It is configured so that a gap G1 is formed. The gap G1 has a gap G between the lacquer portion 5b and the background coating portion 3b described with reference to FIGS. 4 and 5 in the first modification with respect to the edge of the lacquer portion 5b over the entire circumference in the surface direction. It is formed.
In this way, even if the gap G1 is formed in the decorative item 1d, the lacquer portion 5b is formed in the vicinity of the boundary perpendicular to the front and back directions of the background coating portion 3b and the light guide portion 2y, so that the lacquer portion is formed. It is possible to obtain a visual effect (design effect) in which 5b appears to appear three-dimensionally with respect to the background coating portion 3b.

The method for manufacturing the decorative item 1d is the same as the method for manufacturing the decorative item 1b. The specific difference is that when the reflection promoting layer 5d is adhered to the transparent base material 2x and the light shielding / reflecting layer 5a and the lacquer portion 5b are applied to the reflection promoting layer 5d, these are the background coating portion 3a and the light guide. It is a point to be applied so as to be located near the inner side in the surface direction from the boundary with the portion 2y.

In the above embodiment, it has been described that the second decorative portion painted so as to cover the light guide portion 2y from the surface side is the lacquer portion 5b. When the second decorative portion is the lacquer portion 5b in this way, the three-dimensional decoration reflects the light emitted from the surroundings to the lacquer portion 5b, so that the shadow of the lacquer portion 5b can be emphasized. High design effect.
However, the second decorative portion is not limited to the one that has been lacquered, and may be coated with a colored paint. For example, assuming that the second decorative portion is a portion to which a paint of the same color as the background coating portion 3a is applied, no pattern is identified in the state where the light is not emitted from the LED 8, and when the light is emitted from the LED 8. For the first time, the second decorative part may be brought to the surface.

Further, in the decorative item 1b, the light-shielding / reflective layer 5a is provided on the back surface of the lacquer portion 5b, but the light-shielding / reflective layer 5a may be provided on the back surface of the background coating portion 3a. In this way, the light transmitted from the background coating portion 3a can be suppressed, and the contrast between the emitted light 9 and the background coating portion 3a can be emphasized. Therefore, the emitted light 9 can make the lacquer portion 5b appear to stand out more, and the design effect of the decorative item 1b can be enhanced.

The decorative item according to the present invention can be used indoors or outdoors, such as a lantern, a shade of a lighting fixture, a switch panel of a vehicle, a foot light or a garnish, and when used in a dark place, light from a light source. The production of is effective.
