Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wristwatch dial in which a scale ring for displaying time and an abbreviation are integrally formed with a dial substrate.

[Conventional technology]

FIG. 1 shows an embodiment of the prior art, and is a main sectional view of a side structure using a dial plate with abbreviations. FIG. 2 is a plan view of the dial in FIG. 1. FIG. 3 shows another embodiment of the prior art, and is a main sectional view of a side structure using a dial plate provided with a graduated scale ring. Fourth
The figure is a plan view of the dial in FIG. 3. As shown in FIGS. 1 and 2, the conventional wristwatch dial has two fixing protrusions 1a of the dial substrate 1 welded from the back side of the dial substrate 1 to connect it to the mechanical body of the watch. Positioning. On the front side of the dial substrate 1, abbreviations 2 designed to indicate the time were fixed by gluing, welding, caulking, or the like. As another example in the prior art, as shown in FIGS. 3 and 4, a scale ring 13 on which a scale 13a is printed, engraved, or engraved to indicate the time is bonded, welded, caulked, etc. It was fixed to the dial substrate 11 by the screw. The abbreviated characters 2 and the scale ring 13 are manufactured in separate steps from the respective dial substrates 1 and 11,
It was ultimately fixed to the dial substrates 1 and 11.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional technology is composed of two or more parts, such as planting abbreviations on the dial board and planting a scale ring with scales, etc., so each part needs to be molded separately. At the same time, it is necessary to confirm the assembly man-hours for each part and the securing strength of the two parts by assembling them, as well as the man-hour cost, the quality of the securing strength, and the surface pattern and color tone that occur due to separate processing between the two parts. There are many problems such as lack of sense of unity due to differences.

Therefore, the present invention is intended to solve these problems, and its purpose is to streamline the dial by reducing the number of parts that make up the dial, to guarantee the fixing strength of the assembled parts, and to improve the surface pattern, color tone, etc. The objective is to provide a wristwatch dial having the same surface treatment and a sense of unity.

[Means for solving problems]

The wristwatch dial of the present invention has a flat part and a three-dimensional part integrally formed on the outer periphery of the flat part in a direction substantially perpendicular to the flat part, and the three-dimensional part is characterized by comprising a ring-shaped part formed in a ring shape, and a plurality of protrusions for displaying time formed to protrude from the ring-shaped part.

〔Example〕

The present invention will be explained in detail below.

Embodiment 1 FIG. 5 is a main sectional view of a side structure using a dial integrally formed with a three-dimensional shaped part, showing an embodiment of the present invention, and FIG. 6 is an embodiment of the dial in FIG. 5. It is a partial sketch showing an example. Further, FIG. 7 is a partial sketch showing another embodiment of the dial plate in FIG. 5. In FIGS. 5, 6, and 7, the basic side structure is the same as that of the conventional embodiment, but in this embodiment, the outer periphery of the dial 31 is drawn and bent using a die. A three-dimensional shaped portion 31a that is integrally formed and erected substantially perpendicularly from the surface 31b of the dial 31 is formed by, for example, the three-dimensional portion 31a. The three-dimensional portion 31a is integrally formed of a ring-shaped portion 31a-1 and a plurality of protrusions 31a-2 that protrude from the ring-shaped portion in the radial direction. The portion 31a-1 is used as a part of the side parting after the side assembly. In this case, there is no restriction on the planar shape after molding. The patterns on the surface 31b of the dial 31, the ring-shaped part 31a-1, and the protruding part 31a-2, surface finishing such as plating and painting, color tone, printing, etc. are processed in the same process to create a sense of unity in the design. , finished with the same pattern and color tone. In particular, if a scale is printed on the inner side wall of the rising portion of the ring-shaped portion 31a-1, it can be used as a conventional scale ring. The feature of the present invention is that the surface treatment of the dial surface 31b can be extended to the side parting. In addition, three-dimensional shape 3
By providing a plurality of protrusions 31a-2 for displaying the time on the ring-shaped portion 31a-1 of 1a, which protrude in the radial direction, the time can be easily read. Conventionally, in order to make the parting part have the same design as the dial surface, the solution was to install a separate member that was treated in the same way. As a result, there were multiple side structures, which caused trouble and increased unit costs.
In view of the above points, it is possible to make the dial appear larger with a smaller side profile, making it possible to expand the variety of designs never seen before.

Embodiment 2 FIG. 8 is a main sectional view of a side structure using a dial integrally formed with a three-dimensional shaped part, showing still another embodiment of the present invention, and FIG. 9 is a cross-sectional view of the dial in FIG. 8. It is a sketch showing one example. The basic side structure is the same as before. Although the basic aim is the same as in the embodiments shown in FIGS. 5 to 7 above,

form. This part may be patterned, diamond-cut, painted, or otherwise surface-treated and used as part of a design element, or in some cases may be used as an abbreviation for indicating the time. Furthermore, if a scale is printed on the inner side wall of the rising portion of the ring-shaped portion 41a-1, it can be used as a conventional scale ring. Conventionally, the three-dimensional effect was obtained from abbreviations fixed to the dial surface, scale rings, etc., but with the present invention, it is possible to obtain a wide three-dimensional effect, which is useful for expanding design elements. This is an idea.

[Effect of idea]

As described above, according to the present invention, an integrally formed three-dimensional part is provided on the outer peripheral part of the flat part of the dial, standing upright in a direction substantially perpendicular to the flat part,
Moreover, since this three-dimensional part is composed of a ring-shaped part and a plurality of protruding parts, compared to the conventional technology, the dial plate, for example, the scale ring and the plurality of abbreviations are integrated into one part. As a result, the number of parts that make up the dial can be significantly reduced, and the man-hours for processing, assembling, and inspecting each part are significantly reduced. This has the effect of solving problems and reducing costs. Furthermore, since the ring-shaped part can also serve as a parting part on the wristwatch side, the surface treatment of the dial substrate can be extended to the side part and have the same surface treatment, creating a sense of unity. It also has the effect of making it possible to provide a watch dial with an excellent appearance.
