Description

Description: BACKGROUND OF THE INVENTION <Industrial application field> The present invention relates to a timepiece dial, and more particularly to a timepiece having a convex shape such as a time character, a mark, etc., which is made to look higher. Regarding the dial.

<Conventional Technology> In a conventional timepiece dial, a convex portion such as a time character or a mark is formed on a substrate by plating, or a typesetting or the like is fixed on the substrate.

<Problems to be Solved by the Invention> In the case where the above-mentioned convex portions are formed by plating, the thickness is 20 to 30 μm.

Further, the projections can be made thicker by plating, but in this case, it takes a considerable amount of time and has a drawback that mass productivity is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a timepiece dial having a three-dimensional appearance without increasing the thickness of convex portions such as hour letters and marks.

<Means for Solving the Problems> In the present invention, a convex portion such as a letter or mark having a metallic luster formed by plating on a metal substrate is provided, and an apparent position is adjacent to the convex portion. In a timepiece dial having a shadow portion as a shadow, the shadow portion is formed slightly darker than an actual shadow and has a dark color tone.

<Effect> In the present invention, in particular, the convex portion has a shiny metallic luster, and the adjacent portion has a slightly larger dark shade portion, so that the metallic luster is enhanced by the contrast between the convex portion and the shade portion. Some protruding parts look prominent as if they were raised,
Furthermore, it looks high and large as if the size of the shaded portion is present, and gives a three-dimensional effect.

<Example> An example of the present invention will be described below with reference to the drawings. First
FIG. 1 is a sectional view showing a timepiece dial according to a first embodiment of the present invention.

Reference numeral 1 denotes a metal substrate, on which a convex portion 2 having a metallic luster such as a time character or a mark is formed by thick plating such as electroplating.

Reference numeral 3 denotes a shaded portion formed by printing at a position adjacent to the convex portion 2 on the metal substrate 1. The direction of the shaded portion 3 is determined by assuming a shadow that appears when light is applied to the convex portion 2 from a certain direction, and is set slightly larger than the actual shadow, and its color tone is dark. It is set and formed. The shaded portion 3 forms an apparent shadow of the convex portion 2.

Reference numeral 4 denotes a transparent coating made of a transparent resin, which is formed on the metal substrate 1 so as to cover the convex portion 2 and the shaded portion 3, and the upper surface thereof is polished and finished.

The convex portion 2 in this embodiment has a metallic luster because it is formed by thick plating, but its thickness is several tens of microns, and almost no actual shadow appears. However,
By providing the shaded portion 3 as described above, it looks as if a shadow is cast.

In particular, since the convex portion 2 has metallic luster and the shadow portion 3 is formed slightly darker than the actual shadow and is formed in a dark color tone, the convex portion 2 is emphasized in the contour and the shadow portion is formed. The user feels a three-dimensional effect that is judged to be the height at which the shadow appears as large as.

FIG. 2 is a sectional view showing a timepiece dial according to a second embodiment of the present invention.

Reference numeral 5 denotes a metal substrate, on which a convex portion 6 having a metallic luster is formed by thick plating. A colored layer 7 is also provided on the upper surface of the metal substrate 5. This is formed by forming a convex portion 6 by plating, applying a colored coating on the metal substrate 5 from above, and polishing the upper surface of the colored coating so that only the convex portion 6 is exposed. You.

Reference numeral 8 denotes a shaded portion formed by printing on the colored layer 7 and at a position adjacent to the convex portion 6. This shaded part 8 is the first
Similarly to the embodiment, the shadow is formed slightly darker than the actual shadow, and has a color tone of the colored layer 7.

Reference numeral 9 denotes a transparent coating film provided on the metal substrate 5 so as to cover all the convex portions 6, the colored layer 7, and the shaded portions 8.

In the present embodiment, since the colored layer 7 is provided on the metal substrate 5, the color layer 7, the convex portion 6 having metallic luster, and the dark shaded portion 8 differ in color tone and luminance. It is possible to further increase the three-dimensional effect. In particular, the shaded area 8
Is formed in a dark color with the color tone of the color layer 8 on the color layer 7 which is polished and smoothed, so that it looks like a deep shadow close to the actual shadow in the glossy color layer, which is even more pronounced. It brings out the three-dimensional feeling.

FIG. 3 is a sectional view showing a timepiece dial according to a third embodiment of the present invention.

Reference numeral 10 denotes a metal substrate, 11 denotes a colored layer formed by plating or applying a colored coating on the metal substrate 10, and 12 denotes a transparent coating film formed thereon.

Reference numeral 13 denotes a convex portion having a metallic luster such as a time character and a mark.
The convex portion 13 is formed by polishing the upper surface of the transparent coating film 12, depositing a conductive layer on the upper surface, further masking the upper surface with a photoresist, and then performing thick plating. The photoresist and the conductive layer are separated and removed by etching or the like after the formation of the convex portions 13.

Reference numeral 14 denotes a shading portion, which is formed by printing on the transparent coating film 12 and at a position adjacent to the convex portion 13. This shaded part 14
As in the first and second embodiments, the shadow is formed slightly darker than the actual shadow and has a dark color tone.

In the present embodiment, since the transparent coating film 12 is interposed between the convex portion 13 and the colored layer 11, a three-dimensional effect appears as if the convex portion 13 is raised, and the shading portion 14 further enhances the three-dimensional effect. Acts to emphasize.

FIG. 4 is a sectional view showing a timepiece dial according to a fourth embodiment of the present invention.

 Reference numeral 15 denotes a transparent substrate made of sapphire, glass, or the like.

Numeral 16 denotes a convex portion having a metallic luster, which is formed by forming a conductive layer on the upper surface of the transparent substrate 15 by vapor deposition, and further applying a thick mask with a photoresist mask. The photoresist and the conductive layer in this case are then removed.

Reference numeral 17 denotes a shaded portion, which is formed by printing so that it can be seen at the lower surface of the transparent substrate and at a position adjacent to the convex portion 16 when viewed from the upper surface side of the transparent substrate 15. This shaded part 17
As in the previous embodiment, the shadow is formed slightly darker than the actual shadow and in a dark color tone.

Reference numeral 18 denotes a finishing layer provided on the lower surface of the transparent substrate 15 so as to cover the shaded portion 17, and is formed by performing vapor deposition, screen printing, painting, or the like.

Reference numeral 19 denotes a metal substrate, and the upper surface thereof has a convex portion as described above.
The transparent substrate 15 provided with the shading portion 17 and the finishing layer 18 is fixed via an adhesive.

In the present embodiment, since the convex portions 16 and the shading portions 17 are respectively formed on the upper and lower surfaces of the transparent substrate 15, the transparent substrate 15
The depth appears in the shaded portion 17 due to the presence of, and the three-dimensional appearance appears more in the convex portion 16 having a metallic luster.
Further, since the position of the shaded portion 17 is slightly changed depending on the viewing position, a three-dimensional effect can be further increased.

<Effects of the Invention> According to the present invention, a shadow portion serving as an apparent shadow of a convex portion is formed at a position adjacent to a convex portion having a metallic luster, such as a character or a mark, formed by thick plating. By providing it, the shadow part is slightly larger than the actual shadow,
By forming it in a dark color tone, the metallic luster of the protruding part can be seen conspicuously, and at the same time it can be seen with a shadow, with a three-dimensional effect, and the size of the three-dimensional effect is greatly influenced by the size of the shadow. Spawn. Also, by giving the shaded part and the ground color a change in luminance and color tone, the shaded part also has a depth as a shadow, which acts as an effect to further enhance the three-dimensional effect.
