The present invention relates to a ring, and more particularly, to a multi-ring and a method of manufacturing the same by combining two rings integrally to allow a user to produce various designs and atmospheres.

In general, the ring is composed of a ring-shaped body portion made of precious metals such as gold or silver and jewelry or ornaments or various patterns attached to the outer diameter surface of the body portion.

These rings have different tastes for each individual, so they are manufactured to have different designs through various manufacturing methods, such as attaching two or more metals to the surface of the body through manufacturing methods such as plating and welding.

As an example, as shown in Figs. 1 to 3, a double ring 1 is known in which an intermediate ring made of the same or different metal is bonded to the center of the ring. The double ring (1) is to process the groove 11 with the upper and side portions open in the center of the ring body 10, the intermediate ring 20 is fitted to the groove 11 and then coupled to the groove 11 Attaching the separately produced blocking ring 30 to the open side of the groove 11 by welding or adhesive to prevent the fitted intermediate ring 20 is separated, to block the open side of the groove 11, and then smooth the welding site Produced through the user, the user can create a feeling of wearing two different rings at once, thereby greatly increasing customer satisfaction.

However, the conventional double ring as described above has the following problems.

First, since the ring ring 30 is welded or bonded to the ring body 10, a problem occurs that the discolored or cracked portion occurs after a predetermined time.

In addition, when the inner diameter surface of the ring body 10 is expanded or reduced in order to adjust the size of the ring during use, the welded and bonded portions are not stretched and contracted in the same way as the ring body 10, so the cracks on the welded and bonded portions This occurs and leads to a serious problem that the blocking ring is separated from the groove.

In particular, when the inner diameter of the ring body 10 is expanded, the thickness of the welded portion becomes thinner through the finishing operation, and thus the problem is further exacerbated.

It is an object of the present invention to provide a double ring and a method of manufacturing the same, which can be easily manufactured without using welding or an adhesive on the ring body.

In order to achieve the above object, the double ring of the present invention, the main ring having a constant inner diameter, the annular guide groove formed along the outer diameter surface of the main ring, the inner diameter larger than the outer diameter of the main ring and narrower than the guide groove It characterized in that it comprises a sub-ring which has a width and is accommodated inside the guide groove of the main ring when the outer diameter surface of the main ring is expanded.

In addition, the method of manufacturing a double ring according to the present invention includes the steps of manufacturing a main ring having a predetermined inner diameter having an annular guide groove formed along an outer diameter surface, and having a larger inner diameter than the outer diameter of the main ring and a narrower width than the guide groove. And a step of manufacturing the ring and accommodating the sub ring in the guide groove by extending the outer diameter surface of the main ring in a state in which the sub ring is located in the guide groove of the main ring.

The double ring of the present invention configured as described above is manufactured by expanding the main ring in which the guide groove is formed to be accommodated inside the guide groove, so that separate blocking rings as well as the use of welding or adhesive are not required. .

Therefore, the present invention is very easy and quick to make the ring as well as low production cost, there is an effect that can solve various quality problems such as discoloration and cracking due to the use of welding or adhesives at one time.

The features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

DETAILED DESCRIPTION Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Like reference numerals refer to like elements, and only different parts will be mainly described so as not to overlap for clarity.

As shown in FIGS. 4 and 5, the double ring 100 of the present invention has a main ring 110 in which a guide groove 111 is formed and a sub ring 120 coupled in a state accommodated in the guide groove 111. It consists of.

The main ring 110 has a constant inner diameter to be fitted to the user's finger. The guide groove 111 is formed to have a predetermined depth along the outer diameter surface of the main ring 110, it may be formed through the integral molding or post-cutting process when manufacturing the main ring 110.

Accordingly, the main ring 110 has a ring shape in which both sides of the main ring 110 are closed by the guide groove 111 and open only to the outside, and both sides of the main ring 110 closed by the guide groove 111 are closed. The outer diameter surface becomes the outer diameter surface of the main ring 110.

On the other hand, the outer surface of the both ends of the main ring 110 closed by the guide groove 111 may be attached to various ornaments, such as patterns or jewelry to create a colorful appearance of the ring and have a variety of designs.

The main ring 110 is the outer diameter surface is expanded through the post-processing, the outer end of the guide groove 111 of the main ring 110 in the state that the outer diameter surface is expanded to receive the sub ring (120) It must be larger than the inner diameter of 120).

As shown in FIG. 6, the sub ring 120 constituting the present invention is formed to have an inner diameter larger than the outer diameter of the main ring 110, and the width of the sub ring 120 is smaller than the guide groove 111. This is to allow the sub ring 120 to be accommodated in the guide groove 111 when the outer diameter surface of the main ring 110 is expanded, as shown in FIG. 7. Therefore, the outer diameter surface of the sub ring 120 becomes a substantially outer diameter surface of the double ring 100 of the present invention.
