Japanese Utility Model Publication No. 6-23074

  The display plate according to Patent Document 1 has a configuration in which minute strips (hereinafter referred to as brilliant minute pieces) having a reflective surface having a metallic luster are kneaded into a resin layer, so that the color of reflected light depends on how light strikes. This reveals a pattern that changes, and a certain effect can be obtained.

  However, although it has bright fine pieces that change the color of the reflected light, it is used only with natural light without using a phosphorescent paint or backlight, so it is difficult to obtain enough reflected light. In order to obtain reflected light, an extremely large amount of bright fine pieces was used. In reality, it is difficult to obtain sufficient reflected light even when a very large amount of bright fine pieces are used.

  Moreover, since each of the bright fine pieces was kneaded so as to be surrounded by a thick resin, it was further difficult to obtain sufficient reflected light.

  The present invention has been made in view of the above circumstances, and can be used only with natural light without using a phosphorescent paint or a backlight, and can obtain sufficient reflected light without using a very large amount of bright fine pieces. An object of the present invention is to provide a very excellent display panel that can be manufactured and can be easily manufactured and can obtain very strong reflected light.

  A multi-layer plate in which a transparent layer and an opaque layer are formed in a laminated state; and a second reflecting member in which a plurality of bright fine pieces having a reflecting surface are dispersed in an average and irregular state of the reflecting surface; And a first reflecting member, and the multilayer plate is formed with an accommodation recess having an opening in the opaque layer on the back side and having a bottom surface in the transparent layer, and in the accommodation recess, the bottom side of the accommodation recess A transparent base layer, a second reflecting member layer comprising the second reflecting member, and a colored paint layer is applied and formed on the second reflecting member layer. Further, the opaque layer of the multilayer board and the first reflecting layer are formed. A display board having a configuration in which a member is superposed and fixed is used as a means for solving the problem.

  According to the first aspect of the present invention, the multi-layer plate in which the transparent layer and the opaque layer are formed in a laminated state, and the plurality of bright fine pieces having the reflecting surface are in an average and the state of the reflecting surface is irregular. And the first reflective member in the form of a plate, and the multilayer plate has an opening in the opaque layer on the back side and a storage recess having a depth reaching the transparent layer. In the storage recess, a transparent base layer is provided from the bottom side of the storage recess and the second reflection member layer is formed of the second reflection member, and a colored paint layer is applied and formed on the second reflection member layer. Further, since the opaque layer of the multilayer plate and the first reflecting member are superposed and fixed, the light transmitted through the gap between the second reflecting members is reduced even if the amount of the second reflecting member is small. In order to compensate for the amount of reflected light that is reflected by one reflective member, It can be coercive.

  Moreover, by the said structure, when light injects from the surface side, it is reflected in an irregular direction by the 2nd reflective member near the surface side, and it further goes inside from the clearance gap which has arisen in the 2nd reflective member. A part of the incident light is absorbed and reflected by the colored paint layer, and the light further transmitted through the colored paint layer is reflected by the first reflecting member, and a part of the reflected light is a wavelength of the color colored outward. Is emitted, the irregular irregular reflection of the second reflecting member and the reflected light from the gap between the second reflecting member are colored. On the other hand, although the second reflecting member is in a dispersed state in plan, the second reflecting member is located on the transparent underlayer as a whole. Since it superposes | distributes and is disperse | distributing on average, the 2nd reflective member is reflected densely as a whole. Due to the synergistic effect of these reflections, when light from the surface side is incident, it is possible to obtain extremely strong and irregularly reflected light due to irregular reflection.

According to the invention of claim 2, the transparent plate, the multilayer plate made of an opaque plate fixed to the back surface of the transparent plate, and the plurality of bright fine pieces having the reflective surface are average and reflective surface A second reflecting member dispersed in an irregular state and a first reflecting member are provided, and the opaque plate includes a notch-shaped design forming portion, and a plurality of second reflections are provided in the design forming portion. A second reflective member layer formed by dispersing members on average; and a colored coating layer formed by coating on the second reflective member layer; and a back surface of the opaque plate in the multilayer plate and the first Since the reflecting member is superposed and fixed, the incident light reaches the second reflecting member only by passing through the transparent plate, so that stronger reflected light can be obtained, and the second reflecting member is a colored layer. The second reflecting member is arranged so as to be in close contact with the first reflecting member via More densely, it is possible to obtain irregular by diffused reflection, the strong reflected light.

  In addition, when the glittering fine piece in the second reflecting member layer is a polygonal plate-like body, the reflecting surface becomes a polygonal shape, so that the corner of the polygonal plate-like body gives a contour of the reflection state. Brightness and visibility can be improved by forming a large number of flat reflecting surfaces on the side wall of the bright fine piece.

  In addition, by covering the edges of the multilayer board and the first reflecting member that are superposed on each other with a covering material, the boundary between the transparent layer and the opaque layer is shielded from the outside, so that the appearance as a display board can be achieved. Can be improved.

On the other hand, forming a groove-like storage recess for forming a design from the opaque layer side of the multilayer board formed as a laminated state of the transparent layer and the opaque layer, the storage recess has a bottom in the transparent layer, A transparent base layer is formed at the bottom of the storage recess, and then the second reflective member is dispersed and averaged and laminated as a second reflective member layer, and further, a colored paint layer is laminated, After drying, by fixing the first reflecting member from the opaque layer side of the multilayer board, the second reflecting member layer can be very easily formed in the housing recess, and the second reflecting member ( That is, the amount of bright fine pieces can be greatly reduced.

  Further, the opaque plate 7 is fixed to the back surface of the transparent plate, the design forming portion is provided by cutting out only the portion of the opaque plate forming the design, and a plurality of second reflecting members are arranged in an average dispersed manner in the design forming portion. The second reflective member layer is formed, and then the colored coating layer 15 is applied and formed on the second reflective member layer, and after drying the colored paint layer, the first reflective member is fixed to the back side of the opaque plate In the present invention, the opaque plate is fixedly formed at a portion other than the design forming position on the back surface side of the transparent plate, so that the formation of the storage concave portion of the invention according to claim 1 is unnecessary, and the configuration is simpler than the formation of the storage concave portion. It can be manufactured easily and at low cost, and the production efficiency can be greatly improved.

  Furthermore, according to the manufacturing method, sufficient reflected light can be obtained in the same manner by the incident light transmitted through the transparent plate, so that a display plate having irregular and strong reflected light due to irregular reflection can be manufactured. .

  The present invention is based on the second reflecting member in which the light from the surface side is incident, and the reflecting surface is partially polymerized in an irregular state on the plane of the transparent underlayer, and is averagely dispersed. Colored reflected light obtained from the gaps of the second reflecting member is obtained by the dense irregular reflection and the reflection of the first reflecting member through the colored paint layer, and it has a very strong reflected light due to the synergistic action of these and is easy to manufacture. The purpose of providing a simple display board.

  The display board S according to Example 1 of the present invention is an acrylic resin transparent board having a thickness of about 2 millimeters, as shown in a perspective view showing the front side in FIG. 1 and a perspective view showing a partial cross section showing the back side. A multilayer board 1 having a transparent layer 10 and an opaque layer 11 in a laminated state, on which an opaque paint layer is formed on the back surface side, and the acrylic transparent board and the outline of the plate having a thickness of about 0.3 mm The first reflecting member 2 and the wooden plate 3 which are aluminum plates that coincide with each other are sequentially laminated and fixed, and the multilayer plate 1, the first reflecting member 2 and the wooden plate 3 are fixed by an adhesive or the like. In addition, the entire edge portion and the entire wooden board 3 are covered with a decorative paper 4 a that is a covering material 4.

  Here, as shown in FIG. 2, the multilayer plate 1 forms an accommodation recess 12 having an opening on the opaque layer 11 side and having a bottom surface in the transparent layer 10. The storage recess 12 is appropriately formed in a groove shape or a bottomed hole shape, and forms an outline of characters, patterns, symbols, etc. on the display board S.

  In the storage recess 12, from the bottom side of the storage member 12, a colorless and transparent transparent base layer 13, a second reflective member layer 14 made of the bright fine piece 140 a that is the second reflective member 140, a colored paint layer 15 is laminated. In the following description, regarding the lamination in the storage recess 12, the back side of the acrylic synthetic resin plate is described as the upper layer side.

  In the present embodiment, the colorless and transparent transparent underlayer 13 is for fixing the second reflecting member 14, and uses a supernatant of a transparent varnish.

  A second reflecting member layer 14 is provided on the plane of the transparent base layer 13. As described above, the second reflecting member layer 14 is composed of a plurality of bright fine pieces 140a which are the second reflective members 140, and the reflective surface of the bright fine pieces 140a is substantially positive as shown in FIG. Hexagonal shape is a small strip obtained by vapor-depositing an aluminum foil on a resin having a reflective surface width of about 0.5 millimeters, and is called a hologram chip in which the color of reflected light changes depending on the reflection angle. Only the fine pieces having the same size are used as the bright fine pieces according to the present embodiment.

  The glittering fine pieces 140a constituting the second reflecting member layer 14 are scattered almost uniformly on the plane of the transparent underlayer 13, the glittering fine pieces 140a partially overlap each other, and the direction of the reflecting surface is irregular. It has become. Further, the bright fine piece 140a according to the first embodiment is formed as a hexagonal plate-like body.

  The colored paint layer 15 is applied and formed on the second reflective member layer 14, but the colored paint layer 15 itself extends from the gap between the bright fine pieces 140 a constituting the second reflective member layer 14 to the transparent base layer 13. Also formed.

  The multilayer board 1 having the above configuration is fixed to the first reflecting member 2 via a double-sided adhesive tape 16. The double-sided adhesive tape 16 is not provided at a position corresponding to the colored paint layer 15 in the first reflective member 2, and the colored paint layer 15 and the first reflective member 2 are configured to be in a substantially contact state. In addition, a wooden board 3 having an outer contour matching that of the first reflecting member 2 is fixed to the back surface side of the first reflecting member 2 with an adhesive 17.

It is the composition which consists of.

  According to the above-described display panel S according to the first embodiment of the present invention, when natural light is incident from the surface side, the illuminating fine pieces 140a that are the plurality of second reflecting members 140 close to the surface side cause irregular directions. A part of the light incident on the inside from the gap formed between the scattered bright fine pieces 140 a is absorbed and reflected by the colored paint layer 15.

  Of these, the light further transmitted through the colored paint layer 15 is reflected by the first reflecting member 2, and a part of the reflected light is emitted only to the wavelength of the colored color outward, so that the bright fine piece 140 a Irregular irregularly reflected light and colored reflected light reflected from the first reflecting member through the colored paint layer and emitted from the gap between the bright fine pieces 140a are obtained.

  Further, as described above, the colored paint layer 15 is provided on the second reflecting member layer 14, but the paint itself passes from the gap between the bright fine pieces 140 a constituting the second reflecting member 140 to the transparent base layer 13. Since the colored paint layer 15 is present in the part, the color of the paint is directly exposed to the outside, the color of the paint becomes clearer, and the visual effect is improved. It can be done.

  Further, the glittering fine pieces 140a that are the second reflecting member 140 are in a dispersed state in a plan view, and are arranged densely on the transparent foundation layer 13 as a whole, on the plane of the transparent foundation layer 13, Since the reflective surfaces are irregularly oriented and partially polymerized and dispersed on average, the glittering fine pieces 140a are densely reflected as a whole.

  Due to the synergistic effect of the above action, irregularly reflected light by irregular reflection having a very strong shine can be obtained by the incidence of light from the surface side.

  In addition, since the reflecting surface of the glittering fine piece 140a has a hexagonal shape, the reflected light from the corners reaches the eyes, and the outline of the reflecting state becomes clearer than in the case of the circular shape, and the reflecting surface Reflected light having a sharp contour shape of the corners of the corners can be obtained, and since the reflecting surface is a hexagonal shape, the side surfaces are formed as six flat surfaces. By acting as a surface, the brightness of the glittering fine piece 140a itself can be remarkably improved.

(In FIG. 3, for the sake of easy understanding, the thickness ratio is appropriately changed and displayed, for example, by increasing the film thickness of the urethane baking coating portion (that is, the opaque layer).)
Here, the formed groove functions as the housing recess 12.

  Next, a colorless transparent transparent varnish supernatant is applied to the bottom of the storage recess 12 to form a transparent underlayer 13. The upper part of the transparent base layer 13 is formed as a substantially horizontal flat surface, and bright fine pieces 140a as the second reflecting member 140 are spread on the flat surface on average to form the second reflecting member layer 14.

  And a coloring agent is apply | coated with respect to the said brightness | luminance fine piece 140a, and the colored paint layer 15 is formed. Here, Conxten (trade name) manufactured by Washin Paint is used as the colorant in the present embodiment, and a brush is used for coating.

  Of course, the colorant is not limited to the conxten shown as an example, and various known colorants can be used, and various colors can be used in combination. Moreover, also about the coating method, various well-known coating means other than brushes, such as spraying, can be utilized, for example.

  After drying the colorant, the double-sided adhesive tape 16 is applied to the back surface side of the multilayer board 1 except for the opening of the storage recess 12 (that is, the part coated with the colorant), and the first reflecting member The aluminum plate 2 is superposed and fixed.

  Next, the wooden board 3 is bonded to the back surface side of the aluminum plate which is the first reflecting member 2 by using the adhesive 17 and exposed to the entire edge of the multilayer board 1, the first reflecting member 2 and the wooden board 3 and the back surface side. The entire wooden board 3 is covered with the decorative paper 4a, which is the covering material 4, using the adhesive 40, and is completed.

Note that, in the configuration according to the second embodiment, the same configurations as those in the first embodiment will be described with the same reference numerals. As shown in FIG. 4, the display board S according to the second embodiment of the present invention uses a transparent plate 6 and an opaque plate 7 having a metallic luster instead of the multilayer plate 1 shown in the first embodiment. It is.

  Further, as shown in FIG. 4, the opaque plate 7 includes a metallic gloss layer 7a formed by polymerizing a metal thin film on a base material, and adhesive layers 7b and 7c provided on both surfaces of the metallic gloss layer 7a. The display according to Example 1 in that a design forming portion in a notched state, which is a portion for forming a film, is formed and is fixed to the back side of the transparent plate 6 via one of the adhesive layers. This is different from the plate S.

  And the display board S which concerns on the present Example 2 is the part which adheres the opaque board 7 to the back surface side of the transparent board 6 which is a transparent acrylic resin board, and forms the design in an opaque board, as shown in FIG. Only the notch is cut out to provide a design forming portion, and a plurality of bright fine pieces 140a as the plurality of second reflecting members 140 are accommodated in the design forming portion. The opaque plate in this embodiment is provided with a release paper (not shown) on the surface of the adhesive layers 7b and 7c, and is attached to the back surface of the transparent plate 6 on the side of the one adhesive layer 7c. Remove the release paper and stick it.

  Next, the colored coating layer 15 is applied and formed on the bright fine piece 140a, and the release paper on the back surface side of the opaque plate 7 other than the design forming position 18 is peeled off to polymerize the first reflective member 2 made of aluminum onto the adhesive layer 7b. Further, the wooden board 3 is laminated through the adhesive 17, and the entire edge of each of the transparent board 6, the opaque board 7, the first reflecting member layer 2 and the wooden board 3, and the whole wooden board 3 exposed on the back surface side. On the other hand, it can be obtained by adhesively coating the decorative paper 4a which is the covering material 4 using the adhesive 40.

  According to the present embodiment, similarly to the display panel S according to the first embodiment, the amount of the bright fine pieces 140a can be reduced and sufficient reflected light can be obtained, as well as the storage shown in the first embodiment. The formation of the concave portion is unnecessary, the manufacturing can be facilitated and the cost can be reduced, and the bright fine piece 140a, which is the second reflective member 140, is disposed so as to be particularly in close contact with the first reflective member 2 through the colored paint layer 15. As a result, the second reflecting member 140 is more densely packed, and it is possible to obtain irregularly reflected light due to irregular reflection with strong brightness.

  As shown in Example 1 of the present invention, the first reflecting member 2 and the opaque layer 11 of the multilayer board 1 are fixed not only by the double-sided adhesive tape 16 but also by various known adhesives. Means can be used, and the opaque plate 6 shown in Example 2 does not necessarily need to be provided with an adhesive layer on both sides, and various known fixing means can be used.

  Further, without using any fixing means used between the multilayer board 1, the first reflecting member 2 and the wooden board 3, the first reflecting member 2 and the multilayer board 1 or only by the decorative paper 4a. It can also be fixed to the transparent plate 6.

However, the wooden board 3 improves the quality of the display board S, and the corners of the aluminum board do not protrude. It is provided to ensure safety. However, the wood board 3 is not necessarily provided, and as another embodiment shown in FIG. 6, the wood board 3 may not be used at all, or the number of wood boards may be changeable. Instead of the wooden board 3, other buffer materials such as synthetic resin and rubber can be used, and these other buffer materials and the wooden board 3 can be appropriately laminated.

  The covering material 4 and the adhesive material 40 are not necessarily required, and may not be provided depending on the application. In the present embodiment, by using the decorative paper 4a as the covering material 4, it can be used as a very high quality decorative board and the binding property of each layer can be further improved.

  Furthermore, in the present invention, the storage recess includes not only a groove shape but also a bottomed hole shape and the like.

  Further, the bright fine piece in the present invention is not particularly limited as long as it is a fine fine piece having a metallic luster. For example, the so-called so-called fine piece obtained by vapor-depositing an aluminum foil on the resin disclosed in the first and second embodiments. Strips having various metallic luster such as hologram chip strips can be used. In addition, when the hologram chip is used as in the embodiment, the color of the reflected light of the second reflecting member 140 is accompanied by a change in addition to the strong irregularly reflected light having a color due to the colored paint layer. It can be equipped with decorativeness.

  On the other hand, it is sufficient that the opaque layer 7 used in Example 2 is opaque, and it is not always necessary to have a metallic luster. For example, the opaque layer 7 may be a solid pattern or the like. If it is opaque, it can be a synthetic resin film-like thin film. By providing the opaque layer in this way, the reflected light at the design forming position can be recognized more clearly.

  In addition, the first reflecting member in the present invention is an aluminum plate in the first and second embodiments. However, the present invention is not limited to this, and for example, a plate-like body having a mirror surface can be used. Also, a soft film or the like in which a metal film is formed by vapor deposition can be used.

  Furthermore, the multilayer board or the transparent board and the opaque board do not necessarily have to be hard, and the synthetic resin film-like thin film or the like is formed on a soft transparent layer or a soft transparent board of nylon, fluororesin, or polypropylene. It is also possible to laminate an opaque layer or an opaque plate formed as a soft material. For example, as described above, the display plate S can be formed to be soft by combining the first reflective member as a reflective member such as a soft film. Note that soft means not only an elastic material but also a flexible material. The display board S formed as soft can also be formed in a tape shape or the like.
