Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to hour-characters used for dials such as watches and clocks, and more particularly to the structure of two-piece hour-characters that are rich in three-dimensionality and design variation.

[0002]

[Prior art]

 As a conventional time character used for a dial such as a watch or a clock, and having a three-dimensional effect, there is an hour character 11 having a foot 11a for fixing to a dial 12, as shown in FIG. (In general, such time-characters are called typesetting.) The time-characters 11 are formed by press molding (coining) a metal material such as pure copper or brass, which has a large elongation, at the same time as forming the foot 11a. Since the foot 11a is formed by extrusion molding, the foot 11a is very thin (150 to 200 μm), and thus the shape and length are difficult to obtain, and a large load is applied to the mold. As a result, the mold is not easily held, and if it has a complicated shape or a thick one, the mold will be damaged immediately. In the past, only simple shapes and thin ones could be mass-produced.

In addition, when surface treatment such as plating and painting is performed to improve corrosion resistance and aesthetics, since the time character 11 is small, it is batch processing, and only a single color can be obtained.

[0004]

[Problems to be solved by the device]

 In recent years, watches and clocks have become more sophisticated and lower-priced (low-priced), and in particular, there is a growing demand for unprecedented luxury and design variations. For this reason, the conventional hour-mark 11 shown in FIG. 5 is thin, and thus there is a problem that the three-dimensional effect is poor for high-grade products.

Further, there is also a problem that there is a lack of design variation because the color tone of plating, painting, etc. is a single color.

The present invention solves the above-mentioned problems and provides a time character that has a three-dimensional effect and is rich in design variation that allows two colors.

[0007]

[Means for Solving the Problems]

 It is a time character composed of two lower time characters and an upper time character fixed to the upper surface of the lower time character, and is used for plating, painting, vapor deposition, etc. applied to the lower time character and the upper time character. The color tone of the surface treatment is different.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view showing a structure of an hour character according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. As shown in the figure, the hour character 1 of the present invention is a lower hour font 2 having two legs 2a for fixing to a dial, and an upper hour letter 3 is fixed to the upper surface of the lower hour letter 2 by the foot 3a. It has a two-body structure. The lower hour font 2 and the upper hour font 3 are formed by coining a brass material.

With the above structure, the height of the hour character 1 can be increased, and the color tone of the surface treatment of the lower hour letter 2 and the color tone of the surface treatment of the upper hour letter 3 are different from each other. Since it is possible to do so, it is possible to obtain a very variety of hourly characters 1.

In FIG. 1, the shapes of the lower hour font 2 and the upper hour font 3 are shown as square shapes, but the upper hour font 3 may be changed in shape, such as letters and patterns.

FIG. 3 is a sectional view of an essential part showing a state in which the hour character 1 shown in FIG. 1 is fixed to the dial plate 4 by the foot 2 a formed on the lower hour character body 2. As described above, when the hour character 1 of the present invention is used for the dial 4, the color tone of the surface treatment of the dial 4, lower hour font 2 and upper hour font 3 can be changed in various ways so that there is a step, which is very three-dimensional. It is a dial plate with a variety of feelings.

FIG. 4 is a cross-sectional view of an essential part showing a state in which the hour character is fixed to a dial according to another embodiment of the present invention. In the hour character 5 of this embodiment, the upper hour character 7 is fixed to the upper surface of the lower hour character 6 by adhesion, so that the time character 5 is fixed to the dial 8 by caulking or crimping with the foot 6a formed on the lower hour character 6. It is fixed by tightening adhesive. The lower hour character 6 is formed by coining a brass material, and the upper hour character 7 is formed by cutting a transparent polycarbonate and then vapor-depositing Au only on the upper surface. The lower hour font 6 is plated with Pb.

With the above-described configuration, the color tone of the surface treatment of the lower hour font 6 appears from the side surface of the upper hour font 7 depending on the angle at which the dial 8 is viewed, and the time character and the dial are more varied. It will be.

In the present embodiment, the upper hour font 7 is made of transparent polycarbonate, but letters, patterns, etc. formed by electroforming may be bonded together with an adhesive, or the dial 8 may be attached. The fixing may be performed using an adhesive.

[0015]

[Effect of device]

 As described in detail above, according to the present invention, by constructing the hour-character structure with two bodies, the lower hour-character and the upper hour-character, the time-character with a very three-dimensional appearance can be obtained and By changing the color tone of the surface treatment of the font and the lower hour font, it is possible to obtain more diverse hour characters.
