数が多く、製造が煩雑であつた。
Conventionally, clock dials have had characters such as time numerals fixed to the dial, and this dial has been fixed to the dial holder using double-sided tape or the like. Therefore, the number of parts was large and manufacturing was complicated.
この問題を解決する一つの方策として、２色成

板にとつて重大な品質上の問題をもたらすおそれ
があつた。 One way to solve this problem is to integrate the dial and time numerals using two-color molding, but simply adopting two-color molding has the problem of easy peeling. When using a resin that is easy to plate and a resin that is difficult to plate and partially plated with gold or the like, the boundary between the two is not clear, and this results in the appearance of the dial, which is the face of the product. There was a risk that this would lead to serious quality problems.
本考案は、上記実状に鑑みて、上記欠点を生じ
ない２色成形による文字板を提供することを目的
とするものである。 In view of the above-mentioned circumstances, the present invention aims to provide a two-color molded dial that does not suffer from the above-mentioned drawbacks.
この目的を達成するために、本考案に係る２色
成形による文字板は、前面側に文字突起を突設し

脂を使用して、２色成形によつて形成してある。
In order to achieve this purpose, the two-color molded dial according to the present invention has a rear plate body with character protrusions protruding from the front side, and a rear plate body with character protrusions protruding from the front face of the rear plate body. A front plate body having a character hole to be fitted and a rising part formed around the character hole so as to cover the side surface of the character protrusion, one side of which is coated with a resin that is easy to plate, and the other side of which is coated with a resin that is hard to plate. It is formed by two-color molding using resin.
メツキの付き易い樹脂にて形成された後板体と
前板体の一方の前面に無電解メツキが施してあ

は、メツキの切れをよくするための段差が設けて
ある。 Electroless plating is applied to one front surface of the rear plate and the front plate, both of which are made of resin that is easily plated. At this time, a step is provided at the boundary between the character protrusion and the rising portion to improve the sharpness of the plating.
そして、前板体の背面には、後板体と前板体と
が剥離しないように、後板体を貫通して後方に突

固着されるようになつている。 In order to prevent the rear plate and the front plate from peeling off, a mounting part that penetrates the rear plate and projects rearward is integrally formed on the back of the front plate. It is adapted to be fixed to another member, for example, the frame of a watch, via a screw or the like.
以下、本考案の詳細を添付図面に示す一実施例
にそつて説明する。
Hereinafter, details of the present invention will be explained with reference to an embodiment shown in the accompanying drawings.
本考案の文字板１は、二色成形により形成され
ており、後板体２と前板体３とから構成されてい

にはABSなどのメツキの付き易い樹脂が選定さ
れているが、これらの樹脂は相互の融着性が悪
く、剥離し易い問題を有している。 The dial 1 of the present invention is formed by two-color molding, and is composed of a rear plate 2 and a front plate 3. In this embodiment, the rear plate 2 is made of a resin that is difficult to be plated, such as PS (polystyrene), and the front plate 3 is made of resin that is difficult to be plated.
Resins that are easily plated, such as ABS, are selected for this, but these resins have a problem of poor mutual adhesion and easy peeling.
この剥離の問題を解消するために、後板体２と
前板体３とは以下の構造に設計されている。 In order to solve this problem of peeling, the rear plate 2 and the front plate 3 are designed to have the following structure.
後板体２の前面側には、前板体３の前面３ａよ

のタツピング穴が設けてある。１ａは指針軸が貫
通する中心孔、１ｂは前面ガラスの載置部、１ｃ
…はガラス縁の取付部である。 On the front side of the rear plate 2, a character protrusion 2a protruding from the front surface 3a of the front plate 3 is provided. Rear plate 2
Mechanical body mounting claws 2b, 2b and positioning post 2c are protruded from the rear side. Further, the rear plate body 2 is provided with a through hole 2b into which a mounting portion, which will be described later, is fitted. The front plate 3 is provided with a character hole 3b into which the character protrusion 2a of the rear plate 2 projects. A rising portion 3c is formed around the character hole 3b to cover the side surface of the character protrusion 2a. A mounting portion 3d is provided on the back surface of the front plate 3 and protrudes rearward from the through hole 2d of the rear plate 2. The mounting portion 3d is provided with a tapping hole for a mounting screw. 1a is the center hole through which the pointer shaft passes, 1b is the mounting part for the front glass, 1c
... is the mounting part of the glass edge.
そして第４，５図に示されるように、後面部２

る。 Then, as shown in FIGS. 4 and 5, the rear part 2
The character protrusion 2a that projects forward from the front part 3 fits into the character hole 3b of the front part 3, and the attachment part 3d that projects backward from the front part 3 fits into the through hole 2d of the rear part 3. Even if the front plate body 3 and the front plate body 3 are molded in two colors using the resins mentioned above, peeling between the two is unlikely to occur. Particularly, as shown in FIG. 4, at the location where the character protrusion 2a and the attachment part 3c overlap, the character protrusion 2a of the rear plate body 2 and the attachment part 3d of the front plate body 3 are exchanged. Therefore, peeling of two-color molding will never occur.
また、文字突起２ａの前面と立上がり部３ｃの
前面の境界部には、この境界部でのメツキの切れ
を良くし輪郭美しく仕上げるため、文字突起２ａ
の前面と立上がり部３ｃの前面との間に段差が設

上がり部３ｃの前面より突出させてもよい。 In addition, at the boundary between the front surface of the character protrusion 2a and the front surface of the rising portion 3c, in order to improve the sharpness of the plating at this boundary and create a beautiful contour, the character protrusion 2a
A step is provided between the front surface of the rising portion 3c and the front surface of the rising portion 3c. This step may be formed by causing the character protrusion 2a to protrude from the front surface of the rising portion 3c.
なお本実施例では文字板１は二色成形により形
成したが、第４図示のように文字突起２ａと取付
部３ｄとが重ならないようにすれば、後板体２と
前板体３とを文字突起２ａ…と文字孔３ｂ…とに

にしてもよい。 In this embodiment, the dial plate 1 is formed by two-color molding, but if the letter protrusions 2a and the mounting portions 3d do not overlap as shown in the fourth figure, the rear plate body 2 and the front plate body 3 can be easily separated. The character protrusions 2a... and the character holes 3b... or the through holes 2d... and the attachment parts 3d... may be fitted and brought into contact with each other. Further, the rising portions do not need to be provided all around the character protrusion, but may be provided on both sides.
以上述べたように本考案に係る２色成形による

As described above, according to the two-color molded dial according to the present invention, even if two-color molding is performed by selecting a resin that is easy to plate and a resin that is difficult to plate and have mutually poor fusion properties, peeling will not occur. There's nothing to do. In addition to this, a rising part is provided around the character protrusion, so beautiful characters with a border around the character protrusion can be obtained, and a step is added to the boundary between the character protrusion and the rising part, so it is electroless. The plating cuts well when plating, and the decorative properties are good.
