Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and duplicate descriptions are omitted. Also, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from the actual ratios.

[0016] (First Embodiment) <Configuration of Ornament> FIG. 1 is a front view illustrating an ornament according to the first embodiment, and FIG. 2 is a cross-sectional view taken along the line A-A of the ornament shown in FIG. 1. Further, FIG. 3 is a perspective view of the ornament body shown in FIG. 1.

[0017] As shown in FIG. 1, the ornament 100 of the present embodiment has an ornament body 200 and an attachment portion 300. In this specification, ornaments may include tools, accessories, ornaments, adornments, etc. having decorative properties. More specifically, ornaments may include key holders, acrylic stands, miniatures, etc. An acrylic stand is a thing in which an image of a person, a character, etc. is printed on a transparent acrylic plate, the acrylic plate is cut out along the image, and the cut-out image of the character, etc. is inserted into a pedestal to make it stand on its own.

[0018] As shown in FIGS. 2 and 3, the ornament body 200 has a transparent member 210 and a background portion 220. The transparent member 210 constitutes the first layer and can be, for example, a resin member having translucency. When the transparent member 210 has translucency, it means that the transparent member 210 is transparent or translucent. As such a resin having translucency, for example, acrylic, polycarbonate, polyethylene terephthalate, polyvinyl chloride, polystyrene, etc. can be used.

[0019] The transparent member 210 has one surface (hereinafter also referred to as the "first surface") parallel to a plane (X-Y plane) including the X direction in FIG. 1 and the Y direction orthogonal to the X direction, and the other surface (hereinafter also referred to as the "second surface") facing the one surface, and has a thickness in the Z direction (depth direction in FIG. 1). The first surface (hereinafter also referred to as the "surface") S1 and the second surface (hereinafter also referred to as the "back surface") S2 of the transparent member 210 can be formed parallel, for example, but do not necessarily have to be formed parallel. That is, the first surface S1 may be gently inclined with respect to the second surface S2.

[0020] Also, the transparent member 210 is preferably a plate-like member whose length along the X direction and the Y direction is significantly longer than the thickness in the Z direction, but does not necessarily have to be a plate-like member. It is only necessary that the first surface faces the second surface, and the shape of the transparent member 210 may be rod-shaped or polyhedral. The thickness of the transparent member 210 can be, for example, about 3.0 mm to 20.0 mm. The thickness of the transparent member 210 is preferably about 5.0 mm to 10.0 mm.

[0021] The transparent member 210 can have an arbitrary shape (two-dimensional shape) when viewed in plan in FIG. 1. In the figure, the case where the transparent member 210 has a shape with concavo-convex portions in the X direction and the Y direction is illustrated. The transparent member 210 can be circular, elliptical, or polygonal when viewed in plan in FIG. 1.

[0022] A groove portion 211 is formed on the first surface S1 of the transparent member 210. The groove portion 211 has a plurality of linear grooves GR1 formed in the thickness direction of the transparent member 210 to a depth DP1 of, for example, about 1.0 mm to 2.0 mm, more preferably 1.0 mm to 1.5 mm. The width WD1 of each groove GR1 may be, for example, in the range of about 1.0 mm to 3.0 mm, more preferably 1.5 mm to 3.0 mm. Figure 1 illustrates a case in which the transparent member 10 has a grid-like groove portion 211 consisting of a plurality of straight lines extending in the vertical and horizontal directions. It is preferable that two adjacent grooves GR1 be formed generally parallel, but they do not necessarily have to be formed parallel.

[0023] When the groove portion 211 has grooves GR1 formed in a grid pattern, it is preferable that the spacing PT1 of the grooves GR1 be formed to be approximately equal in both the vertical and horizontal directions, but it is not necessarily required that the spacing PT1 of the grooves GR1 be equal throughout the entire area. For example, the spacing PT1 of the grooves GR1 may be different in a part of the area of ​​the first surface S1. The spacing PT1 of the grooves GR1 may be, for example, in the range of 1.0 mm to 15.0 mm, more preferably in the range of 1.5 mm to 10.0 mm, in both the vertical and horizontal directions. By setting the spacing PT1 of the grooves GR1 to the range of 1.5 mm to 10.0 mm, the effect of the pattern appearing three-dimensional can be enhanced. In addition, the number of grooves in the groove portion 211 may be appropriately determined considering the effect on the viewer's vision, as will be described later.

[0024] The first surface S1 and the second surface S2 of the transparent member 210 are preferably flat, but they do not necessarily have to be flat over their entire surface; they may have concave or convex surfaces in some parts.

[0025] The background portion 220 serves as a second layer and includes a printed layer, painted layer, or film-covered layer formed on the second surface S2 of the transparent member 210. The pattern displayed on the second surface S2 by the printed layer, painted layer, or film-covered layer may be of any shape as long as it is visible to the viewer of the decorative item 100 through the first surface S1 of the transparent member 210. The pattern displayed on the second surface S2 may be, for example, a color or monochrome pattern, image, or photograph formed by colored toner or paint. If the groove portion 211 has grooves GR1 formed in a grid pattern, the pattern is divided by the grid-patterned grooves GR1 and includes multiple dots DT1 whose vertical and horizontal sides correspond to the spacing PT1 of the grooves GR1. The pattern can be represented by the arrangement of the dots DT1. Since the background portion 220 is formed by printing or painting, the pattern can be formed on the second surface S2 of the transparent member 210 without the hassle of attaching multiple acrylic plates.

[0026] Thus, in this embodiment, the background portion 220 has a dot pattern design with multiple dots in the X and Y directions when viewed from above. Figure 1 illustrates a case where a dot pattern has a complex contour due to the unevenness of the dots, each dot is assigned a color, and the dot pattern as a whole has the shape of a specific character.

[0027] The mounting portion 300 has a mounting member for attaching the decorative item body 200 to other components. The mounting member may be, for example, a ball chain. The decorative item body 200 has a through hole TH through which the mounting member can be inserted. The through hole TH is formed, for example, at the end of the decorative item body 200.

[0028] <Manufacturing method for 100 decorative items> Figure 4 is a flowchart illustrating the processing steps for the manufacturing method of the ornament shown in Figure 1. First, in the first step (step S01), the transparent member 210 is formed. The manufacturer of the ornament 100 prepares a transparent plate-like member. The transparent plate-like member may be, for example, an acrylic plate. More specifically, the manufacturer of the ornament 100 forms the transparent member 210 by cutting the acrylic plate into a desired shape. The cutting of the acrylic plate may be performed using equipment such as a laser processing machine based on the shape data of the transparent member 210, or it may be done manually by the manufacturer using a laser cutter. In addition, in the first step, the cut plate-like member may be further processed by chamfering or polishing.

[0029] Next, in the second step (step S02), a background portion 220 is formed on the transparent member 210. The background portion 220 includes a pattern that can be seen by the viewer through the first surface S1 of the transparent member 210. That is, contrary to printing or painting on paper, the pattern is printed or painted on the second surface S2 of the transparent member 210 so that when the background portion 220 is viewed from the first surface S1 to the second surface S2 of the transparent member 210, the left and right sides of the pattern on the background portion 220 are correct. When the pattern of the background portion 220 is formed by printing, the background portion 220 including the pattern can be formed on the transparent member 210 by a printing press based on the pattern data.

[0030] Next, in the third step (step S03), grooves 211 are formed in the transparent member 210. More specifically, grooves 211 are formed by irradiating the first surface S1 of the transparent member 210, opposite to the second surface S2 (the surface on which the background portion 220 is formed), with a laser using a laser processing machine to form a grid-like groove GR1. The grooves 211 are formed at positions corresponding to the pattern of the background portion 220. By forming grooves 211 in the transparent member 210 on which the background portion 220 is formed, the decorative item body 200 is completed.

[0031] The grooves 211 can be formed using a laser processing machine used for cutting and engraving acrylic sheets. The laser irradiation output of the laser processing machine is set to a value that can form narrow grooves of depth DP and width WD on the surface of the acrylic sheet.

[0032] Next, in the fourth step (step S04), the ball chain is attached to the ornament body 200 by the maker passing it through the through hole in the ornament body 200. This completes the ornament 100.

[0033] Thus, in the flowchart shown in Figure 4, a transparent member 210 is formed, and a background portion 220 is formed on the formed transparent member 210. Next, a groove portion 211 is formed on the side of the transparent member 210 opposite to the side on which the background portion 220 is formed. Then, the ball chain is attached to the ornament body 200, completing the ornament 100.

[0034] In the decorative item 100 of the first embodiment described above, a grid-like groove portion 211 is formed on the first surface S1 of the transparent member 210, which is opposite to the second surface S2 on which the background portion 220 including the design is formed. This reduces the effort required to manufacture the decorative item 100 while giving the design displayed by the decorative item 100 a three-dimensional feel.

[0035] <100 examples of decorative items> Figure 5 is a photograph of the ornament body manufactured by the manufacturing method shown in Figure 4, viewed from roughly the front, and Figure 6 is a photograph of the ornament body shown in Figure 5, viewed from an oblique angle. As described above, the ornament body 200 has a transparent member 210 and a background part 220, with the background part 220 having a pattern formed on the back surface opposite to the surface of the transparent member 210 where the groove 211 is formed. Viewers of the ornament 100 appreciate the pattern on the background part 220 through the transparent member 210.

[0036] As shown in Figure 6, with the ornament body 200 of this embodiment, the pattern on the background portion 220 formed on the opposite side of the transparent member 210 appears to the viewer as if it is floating. This is thought to be because when light incident on the transparent member 210 is reflected off the surface of the background portion 220 and emitted outwards from the ornament 100 through the transparent member 210, some of the reflected light is scattered in the groove portion 211 and reaches the viewer's eye via a complex path. As a result, the dots that make up the pattern on the ornament 100 appear to float, and the pattern appears three-dimensional to the viewer. In addition, the intensity of the scattered light from the groove portion 211 changes depending on how light hits the ornament 100 and the angle at which the viewer views the ornament 100, resulting in different appearances of the pattern. Viewers can enjoy the changes in the appearance of the pattern by changing the intensity and direction of the light hitting the ornament 100 and the angle from which they view the ornament 100.

[0037] The ornament 100 of the first embodiment described above provides the following effects.

[0038] In this embodiment, the decorative item 100 has a grooved portion 211 with a grid pattern formed on the side opposite to the side on which the background portion 220 with the pattern is formed in the transparent member 210. This allows the decorative item 100 to display a three-dimensional pattern while reducing the effort required for manufacturing.

[0039] (Second embodiment) In the first embodiment, the case in which the groove portion 211 has grooves GR1 formed in a grid pattern was described. In the second embodiment, the case in which the groove portion has grooves that include curves in addition to straight lines will be described. In order to avoid duplication of explanation, the description of the same configuration as in the first embodiment will be simplified or omitted.

[0040] Figure 7 is a front view illustrating an ornament according to the second embodiment of the present invention, and Figure 8 is a perspective view illustrating the ornament shown in Figure 7. As shown in Figure 7, the ornament 400 of this embodiment has an ornament body 500 and a mounting part, and the ornament body 500 has a transparent member 510 and a background part 520. In Figures 7 and 8, the mounting part (for example, a ball chain) is not shown in order to simplify the explanation. The configuration of the transparent member 510 and the background part 520 is generally the same as the configuration of the transparent member 210 and the background part 520 in the first embodiment, respectively, but in the second embodiment, the shape of the transparent member 510 is different from that of the transparent member 210 in the first embodiment. In this embodiment, the shape of the transparent member 510 when viewed from above is generally rectangular. Also, Figures 7 and 8 illustrate the case where the pattern of the background part 520 is a photograph of a person.

[0041] Furthermore, the transparent member 510 has a groove 511, and the groove 511 has a linear groove GR2 that includes straight and curved sections. In Figures 7 and 8, the shape of the groove GR2 of the groove 511 is similar to, for example, the shape of the outline of a jigsaw puzzle piece. The shape of the groove GR2 is not limited to the shape of a jigsaw puzzle piece, but can be formed into a variety of shapes.

[0042] The depth (not shown) and width WD2 of groove GR2 may be approximately the same as, for example, the depth DP1 and width WD1 of groove GR1 in the first embodiment. Furthermore, the spacing PT2 between adjacent straight sections of groove GR2 may be larger than the spacing PT1 of groove GR1 in the first embodiment, but is not limited to this case. The spacing PT2 of groove GR2 may be, for example, within the range of 2.5 mm to 100.0 mm in both the vertical and horizontal directions. As shown in Figure 8, similar to the ornament 100 in the first embodiment, the ornament 400 in this embodiment also has the effect of making the pattern appear three-dimensional due to light scattering in the groove 511.

[0043] The ornamental item 400 of the second embodiment described above provides the following effects in addition to the effects of the first embodiment.

[0044] For example, something that is normally separate and unsuitable for carrying around, like the pieces of a jigsaw puzzle, can be carried around in a way that allows the design to be appreciated, like a keychain. In addition, the shape of the groove GR2 of the groove 511 is added to the design of the background 520, providing the viewer with a fresh impression that was not present in the original design.

[0045] As described above, the embodiments have explained the ornaments and the methods for manufacturing the ornaments. However, it goes without saying that those skilled in the art can add, modify, and omit as appropriate within the scope of the technical concept of the present invention.

[0046] For example, in the first and second embodiments, the case was illustrated in which a background portion is formed on the back surface of the transparent member and then a groove portion is formed on the surface of the transparent member, but the order in which the background portion and the groove portion are formed may be reversed.
