Abstract

The invention relates to a watch bezel and a method for manufacturing the watch bezel. According to the present invention, index grooves (140) are formed in the watch bezel (100) of a wristwatch by engraving the index grooves so that the index grooves conform to respective indexes, and index elements (200) formed to conform to the index shapes are inserted into the respective engraved index grooves. The index elements are fixed by adjustment to the press or by gluing. As a result, the indexes are stable and are not distorted.

Description

The present invention relates to a watch bezel and a method for manufacturing the latter, more particularly a watch bezel on which indexes such as numbers, are stable and are not deformed, and a method for manufacturing the bezel of shows.

In general, a bezel means an edge portion for fixing a glass on a watch plate. Indexes such as numbers or graduations, are indicated on the telescope to display the minutes.

[0003] Recently, a product has been presented in which a jewel such as diamonds has been placed in the bezel in order to give a luxurious image to the appearance of the watch.

In addition, the bezel is mainly made from metal, but recently was made from ceramics.

[0005] A related prior art includes the publication of the Korean patent 10-2011-0 022 045, which is entitled "Decorative article produced by inlaying".

The prior art is briefly described below. The prior art relates to a method for fixing one or more aesthetic elements on a support, comprising the steps of providing the support made from a first material, providing the one or more aesthetic elements made with a second material, and embedding the one or more elements in the support. More particularly, the prior art relates to a method for attaching aesthetic elements in which one or more of the first material and the second material are amorphous type materials to facilitate the incrustation step.

Therefore, in the prior art, the aesthetic elements are fixed on the support by means of inlay, that is to say by hot forming.

However, in a conventional technique, a bezel is mainly formed by printing indexes on the bezel or by performing a method of engraving on the bezel in response to the indexes and then by injecting paint on the bezel.

However, the conventional technique is problematic in that the indexes fade or the color of the indexes deforms.

Therefore, the present invention has been realized keeping in mind the above problems that are encountered in the prior art, and an object of the present invention is to provide a watch bezel in which indexes, such as numbers, formed in the watch bezel are stable and reliable without being deformed, forming grooves corresponding to the indexes in the watch bezel and combining an index material with the grooves and a method for manufacturing the watch bezel.

In order to achieve the object above, the present invention provides a method for forming indexes of a watch bezel, comprising a first step of forming index grooves in the watch bezel of a wristwatch by engraving the index grooves so that the index grooves conform to the respective index shapes and a second step of inserting formed index elements to conform to the index shapes in the indexes. respective engraved index grooves.

The method further comprises a third step of grinding surfaces of the index members and the watch bezel to assign an identity to the surfaces of the index members and the watch bezel after the second step. .

In the second step, the index elements are formed to have different colors of the watch bezel and are made from different materials of the watch bezel.

In the first step, the index grooves are formed by laser cutting.

In the second step, the index elements are glued to the index grooves or the index elements are combined with the index grooves by means of an adjustment to the press.

An annular groove is formed in the outer circumferential surface of each of the index members, an annular member is inserted into each of the annular grooves, and the annular member is inserted into an inner circumferential surface of each of the grooves. index.

In the second step, the index element is combined with the index groove to form the same plane as an upper surface of the index grooves.

In the second step, the index member protrudes further than the index groove.

The index groove is formed to penetrate the watch bezel from top to bottom.

[0020] A concave groove is an inner circumferential surface of the index groove, and a bump portion is formed in the index member and combined with the concave groove. <tb> Fig. 1 <SEP> is a process flowchart illustrating a method for making a watch bezel according to the present invention; <tb> fig. 2 <SEP> is an exploded perspective view of the watch bezel according to the present invention; <tb> fig. <SEP> is a sectional view illustrating a method for manufacturing a watch bezel according to a first embodiment of the present invention; <tb> figs. 4 and 5 <SEP> are sectional views of the completed watch bezel according to the method of FIG. 3; <tb> fig.
