Detailed Implementation

[0018] Hereinafter, clock 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0019] Figure 1 This is a front view showing clock 1. In this embodiment, clock 1 is configured as a wristwatch worn on the user's wrist.

[0020] like Figure 1 As shown, the clock 1 has a metal case 2. Inside the case 2 are a circular dial 10, a second hand 3, a minute hand 4, an hour hand 5, a crown 7, a button A 8, and a button B 9. The dial 10 has a main body 11 and time markers 12 provided on the main body 11. The dial 10 is an example of a clock component of the present invention.

[0021] [Dial Body]

[0022] Figure 2 This is a cross-sectional view showing the main parts of the dial body 11. Additionally, Figure 2 It is a cross-sectional view of the substrate 30 in the main body 11 of the dial, cut along the thickness direction.

[0023] like Figure 2 As shown, the main body 11 of the dial is configured to include a substrate 30, a multilayer film 31, a first transparent film 32, and a second transparent film 33. In this embodiment, the substrate 30 is entirely covered by the multilayer film 31. That is, the multilayer film 31 is stacked in such a way that it covers the entire surface 301 of the substrate 30.

[0024] In addition, the main body of the dial 11 is not limited to the above structure. For example, a multilayer film 31 may be laminated to cover a portion of the surface 301 of the substrate 30.

[0025] [Substrate]

[0026] The substrate 30 is made of metals such as iron, brass, and aluminum, or resin. In the case where the substrate 30 is made of resin, the resin can be a non-transparent resin that does not allow light to pass through, or it can be a transparent resin that allows light to pass through.

[0027] Furthermore, in this embodiment, any pattern is formed on the surface 301 of the substrate 30. The method of forming the pattern is not particularly limited, and for example, it can be formed by machining, laser machining, chemical removal machining, grinding machining, forging / casting machining, etc.

[0028] [Multilayer film]

[0029] The multilayer film 31 is configured to have a color absorption film 311 and a color adjustment film 312, which are laminated on the surface 301 of the substrate 30.

[0030] The color absorption film 311 is formed using a metal. Preferably, the metal constituting the color absorption film 311 is Ag, Pt, Au, Cu, Al, Cr, Sn, Fe, Ti, or alloys thereof. In this embodiment, two layers of the color absorption film 311 are formed in a manner that they are stacked on top of the color adjustment film 312.

[0031] There are no particular limitations on the method for forming the color absorption film 311, and examples include ion-assisted evaporation, ion plating, vacuum evaporation, and sputtering. Therefore, the layer structure of the multilayer film 31 can be arbitrarily varied.

[0032] The color adjustment film 312 is a film that adjusts hue through optical interference. In this embodiment, five layers of color adjustment film 312 are formed. That is, a multilayer film 31 consisting of seven layers, namely the color absorption film 311 and the color adjustment film 312.

[0033] Furthermore, in this embodiment, the color adjustment film 312 is configured as a film comprising an inorganic film. Specifically, the color adjustment film 312 is preferably composed of Ta2O5, SiO2, TiO2, Al2O3, ZrO2, Nb2O5, HfO2, or Na5Al3F. 14 It is composed of at least one of Na3AlF6, AlF3, MgF2, CaF2, BaF2, YF3, LaF3, CeF3, and NdF3. Therefore, these inorganic substances have high chemical stability, thus improving the stability and durability of the appearance of watch components.

[0034] Furthermore, there are no particular limitations on the method for forming the color adjustment film 312, and examples include ion-assisted evaporation, ion plating, vacuum evaporation, and sputtering. Therefore, the layer structure of the multilayer film 31 can be arbitrarily varied.

[0035] [First transparent membrane]

[0036] The first transparent film 32 is a transparent film stacked on the multilayer film 31, having a specified refractive index and allowing a portion of the incident light to pass through. In this embodiment, the first transparent film 32 is formed of an epoxy coating and has a refractive index of 2.2.

[0037] Furthermore, the first transparent film 32 is laminated onto the multilayer film 31 in an arbitrary pattern. That is, when viewed from above in the thickness direction of the substrate 30, there are regions where the first transparent film 32 is formed and regions where the first transparent film 32 is not formed. In other words, there are regions where the first transparent film 32 is laminated onto the multilayer film 31 and regions where the multilayer film 31 is exposed. That is, the first transparent film 32 is formed locally relative to the multilayer film 31.

[0038] [Second transparent membrane]

[0039] The second transparent film 33 is a transparent film laminated on the first transparent film 32 or the multilayer film 31, having a predetermined refractive index and allowing a portion of the incident light to pass through. Specifically, the second transparent film 33 is laminated on the first transparent film 32 at the locations where the first transparent film 32 is formed, and laminated on the multilayer film 31 at the locations where the first transparent film 32 is not formed. In other words, the second transparent film 33 is laminated on the multilayer film 31 where the first transparent film 32 is partially formed.

[0040] Furthermore, in this embodiment, the second transparent film 33 is formed of acrylic coating and has a refractive index of 1.6. That is, in this embodiment, the second transparent film 33 has a refractive index that differs from the first transparent film 32 by a predetermined difference. More specifically, the second transparent film 33 has a refractive index that differs from the first transparent film 32 by 0.6.

[0041] Thus, in this embodiment, the dial 10 has a region in which multiple layers of film 31, a first transparent film 32, and a second transparent film 33 are stacked relative to the substrate 30.

[0042] [Dial Manufacturing Method]

[0043] Figure 3 This is a diagram showing the manufacturing process of the dial body 11 of the dial 10. Figure 4 This is a schematic front view showing the main body of the dial 11.

[0044] like Figure 3 As shown, firstly, as a substrate pattern forming process, a pattern is formed on the surface 301 of the substrate 30 of the dial body 11 by processing such as cutting, laser processing, chemical removal processing, grinding processing, forging / casting processing, etc.

[0045] Next, as a multilayer film formation process, a multilayer film 31 is laminated on the surface 301 of the substrate 30 of the dial body 11. Specifically, a color absorption film 311 and a color adjustment film 312 are laminated on the surface 301 of the substrate 30 by means of ion-assisted evaporation, ion plating, vacuum evaporation, sputtering, etc.

[0046] In addition, Figure 3The image shows a state in which a multilayer film 31 is stacked on the patterned surface 301 of the substrate 30.

[0047] Next, as a first transparent film forming step, a first transparent film 32 is formed on the multilayer film 31. Specifically, an epoxy coating is applied to the multilayer film 31 in an arbitrary pattern using an inkjet printer to form the first transparent film 32. In this embodiment, the first transparent film 32 is formed in a pattern resembling multiple lightning bolt symbols. In this embodiment, since the first transparent film 32 is formed using an inkjet printer, it is easy to form a first transparent film 32 with an arbitrary pattern.

[0048] Next, as a second transparent film forming step, a second transparent film 33 is formed by laminating it onto the first transparent film 32 or the multilayer film 31. Specifically, an acrylic coating is applied to the first transparent film 32 or the multilayer film 31 using an inkjet printer, thereby forming the second transparent film 33. That is, an acrylic coating is applied to the multilayer film 31 on which the first transparent film 32 is partially formed using an inkjet printer, thereby forming the second transparent film 33. At this time, the second transparent film 33 is formed such that the absolute value of the difference in refractive index between it and the first transparent film 32 is 0.06 or more.

[0049] The main body 11 of the dial is formed in this way, such as Figure 4 As shown, the dial body 11 can be painted with any color through the multilayer film 31.

[0050] Furthermore, since the refractive indices of the first transparent film 32 and the second transparent film 33 are different, different hues can be displayed in the areas where the first transparent film 32 is formed and in the areas where the first transparent film 32 is not formed. In other words, the refractive indices of light transmitted through the first transparent film 32 and the second transparent film 33, where the multilayer film 31 and the substrate 30 are visible, are different from those transmitted through the second transparent film 33 alone, thus enabling the display of different hues. Therefore, the pattern of the first transparent film 32 can be identified based on the difference in hue, allowing for the display of arbitrary patterns and improving design flexibility.

[0051] Furthermore, in this embodiment, since any pattern is applied to the substrate 30 of the multilayer film 31, a multilayer and complex pattern can be expressed by the pattern applied to the substrate 30 and the pattern of the first transparent film 32.

[0052] Figure 5 This is a diagram showing the relationship between the refractive index difference between the first transparent film 32 and the second transparent film 33, and the color difference between the area with the first transparent film 32 and the area without the first transparent film 32 when viewed from above on the main body 11 of the dial. Additionally, in Figure 5In this study, the hue of the dial body 11, which has a first transparent film 32 with various refractive indices, was measured using a second transparent film 33 formed by coating with acrylic paint and a multilayer film 31 with five hues: deep blue, green, gray, purple, and light blue. As the hue measurement conditions, L was calculated using average reflected light with an incident angle of 0° in CIE 1964 space with the CIE standard light source D65. a b Additionally, in Figure 5 In the figure, the value obtained by subtracting the refractive index of the first transparent film 32 from the refractive index of the second transparent film 33 is shown as the refractive index difference.

[0053] like Figure 5 As shown, the hues of the five colors—dark blue, green, gray, purple, and light blue—all provide the following insights: as the absolute value of the difference in refractive index increases, the color difference between the area where the first transparent film 32 is formed and the area where the first transparent film 32 is not formed increases.

[0054] In particular, the following insight is provided: when the absolute value of the difference in refractive index between the first transparent film 32 and the second transparent film 33 is 0.06 or more, the color difference between the area where the first transparent film 32 is formed and the area where the first transparent film 32 is not formed becomes 1.6 or more. Generally speaking, a color difference of 1.6 or more is required to distinguish color differences. Therefore, by making the absolute value of the difference in refractive index between the first transparent film 32 and the second transparent film 33 0.06 or more, the color difference between the area where the first transparent film 32 is formed and the area where the first transparent film 32 is not formed can be made 1.6 or more, and the difference in hue can be more reliably distinguished. Therefore, this provides the insight that any pattern represented by the pattern of the first transparent film 32 can be distinguished.

[0055] [Effects of the Implementation Method]

[0056] According to this embodiment, the following effects can be obtained.

[0057] In this embodiment, a multilayer film 31 is provided, which covers at least a portion of the substrate 30 and includes a color adjustment film 312 with a function of adjusting hue, thus enabling arbitrary hues to be applied to the dial 10. Furthermore, in this embodiment, since a first transparent film 32 formed with an arbitrary pattern and a second transparent film 33 having a refractive index having a predetermined difference from the first transparent film 32 are laminated on the multilayer film 31, different hues can be expressed in the areas where the first transparent film 32 is formed and in the areas where the first transparent film 32 is not formed. Therefore, arbitrary patterns can be expressed through the pattern of the first transparent film 32, thereby improving design flexibility.

[0058] In this embodiment, an arbitrary pattern is formed on the surface 301 of the substrate 30 covered by the multilayer film 31. Therefore, in addition to the pattern represented by the pattern of the first transparent film 32, the pattern formed on the substrate 30 can also be represented. Thus, more complex patterns can be represented.

[0059] In this embodiment, since the first transparent film 32 is formed with an arbitrary pattern by an inkjet printer, the first transparent film 32 with an arbitrary pattern can be easily formed relative to the multilayer film 31.

[0060] In this embodiment, the absolute value of the difference in refractive index between the first transparent film 32 and the second transparent film 33 is 0.06 or more. Therefore, the difference in hue between the area where the first transparent film 32 is formed and the area where the first transparent film 32 is not formed can be more reliably identified. Thus, any pattern represented by the pattern of the first transparent film 32 can be identified.

[0061] In this embodiment, when viewed from above along the thickness direction of the substrate 30, the color difference between the area where the first transparent film 32 is formed and the area where the first transparent film 32 is not formed is 1.6 or more. Therefore, the color difference between the areas where the first transparent film 32 is formed and the areas where the first transparent film 32 is not formed can be more reliably identified. Thus, any pattern represented by the pattern of the first transparent film 32 can be identified.

[0062] [Variation Example]

[0063] Furthermore, the present invention is not limited to the aforementioned embodiments, and variations and improvements within the scope of achieving the objectives of the present invention are included in the present invention.

[0064] In the above embodiment, the multilayer film 31 is composed of 7 layers, including 2 color absorption films 311 and 5 color adjustment films 312, but it is not limited to this. For example, the multilayer film 31 may be composed of 8 or more color absorption films and color adjustment films, or it may be composed of 6 or fewer layers.

[0065] In the above embodiments, patterns are formed on the substrate 30 using processes such as cutting, laser processing, chemical removal, grinding, forging / casting, etc., but the process is not limited to these methods. For example, mirror finishing or leveling (full-surface finishing) can be performed on the surface of the substrate. That is, multiple layers of film, a first transparent film, and a second transparent film can be laminated relative to the unpatterned substrate.

[0066] In the above embodiment, a multilayer film 31, a first transparent film 32, and a second transparent film 33 are laminated relative to the substrate 30 of the dial body 11, but this is not a limitation. For example, a multilayer film and a second transparent film may be laminated relative to the substrate 30 of the dial body, and the multilayer film, the first transparent film, and the second transparent film may be laminated at positions corresponding to the time markers. That is, the pattern of the first transparent film may be formed in a way that can represent the time markers. With this configuration, different hues can be displayed at the dial body and the time markers, thus making the time markers identifiable in the dial body.

[0067] In the above embodiments, the first transparent film 32 is formed in any pattern by an inkjet printer, but is not limited to this. For example, the first transparent film can be formed in any pattern by ion-assisted evaporation, ion plating, vacuum evaporation, sputtering, etc.

[0068] Similarly, in the above embodiments, the second transparent film 33 is formed by an inkjet printer, but is not limited to this. For example, the second transparent film can be formed in any pattern by ion-assisted evaporation, ion plating, vacuum evaporation, sputtering, etc.

[0069] In the above embodiments, the watch component of the present invention is configured as a dial 10, but is not limited thereto. For example, the watch component of the present invention may also be configured as any one of a pendulum, a hand, a bezel, and a watch strap.

Furthermore, in this invention, since a first transparent film formed with an arbitrary pattern and a second transparent film having a refractive index having a predetermined difference from the first transparent film are laminated relative to the color-adjusting film, different hues can be expressed in the areas where the first transparent film is formed and in the areas where the first transparent film is not formed.
