- In addition, a plurality of viewing holes (13) are formed along outer circumferential surface of the outside ring (10) for seeing the inside ring (20) from the outside.
- Furthermore, the inside ring may be constructed in the form of mesh (net).
- In the following, the detailed construction and example of the present invention will be described with reference to the drawings.
- The outside ring (10) according to the present invention is produced by casting and the inside ring (20) is injection-molded. First, a process of producing the outside ring (10) will be described as follows.
- In a first step, a design of a ring to be produced is planned and drawn.
- Then, in a second step, a mold is produced with particular resin.
- Then, in a third step, the mold produced in the second step is divided into two equal parts, and inner surface of the halved mold is then shaped in intaglio according to the design of the ring drawn in the first step.
- Furthermore, in a fourth step, the mold shaped in the third step is fixed in such a manner that the cut sections are joined, and thereafter, molten liquid paraffin is injected into the interior of the shaped mold.
- Then, in a fifth step, drying is carried out so that the paraffin injected in the fourth step is cured, and if the paraffin is cured, the mold is divided again into the two equal parts to extract a paraffin model molded in the interior of the mold.
- Furthermore, in a sixth step, gypsum is applied onto the paraffin model extracted in the fifth step to obtain a gypsum mold.
- In a seventh step, the gypsum mold obtained in the sixth step is heated to melt the paraffin accommodated inside the gypsum mold and thereafter discharge the same outward.
- Then, in an eighth step, molten liquid metal is injected into the interior of the gypsum mold that has been previously occupied by the paraffin discharged in the seventh step.
- Furthermore, in a ninth step, the molten liquid metal which was injected into the interior of the gypsum mold in the eighth step is cooled.
- In a tenth step, the gypsum mold with a metal casting cooled therein is separated to extract the ring formed in the gypsum mold.
- Then, in an eleventh step, the ring which has been extracted from the gypsum mold in the tenth step is lustrously processed.
- In the following, a process of producing the inside ring (20) will be described.
- First, in a first step, the inside ring is designed based on the design of the outside ring, and an injection mold is designed accordingly.
- Then, in a second step, the injection mold designed in the first step is produced.
- In a third step, the injection mold is mounted on an injection molding machine to produce the inside ring.
- The ring of the present invention produced by the above-described processes comprises the outside ring (10) with a fixed inner diameter and the inside ring (20) coupled with the outside ring (10) to define the inner diameter, as illustrated in
FIGS. 1 a and 1 b, wherein the coupling groove (11) of “” shape is formed in the outside ring (10) along the inner circumferential surface thereof, and the separation prevention ridges (12) are formed in the coupling groove (11) in order to prevent the inserted inside ring (20) from coming off the groove. - In other words, the coupling groove (11) is formed so as to be widened as going deeply into the groove, thus the separation prevention ridges (12) of acute angle are formed on lateral surfaces of the coupling groove (11), respectively. Therefore, if the inside ring is inserted and coupled in the coupling groove (11), the inside ring (20) is prevented from coming off the groove by the separation prevention ridges (12).
- Thus, the inside ring (20) is inserted in the coupling groove (11) of the outside ring (10) to define the inner diameter of the ring (30), and the inside ring is made of material such as silicone, rubber etc. harmless to human body and blocks the contact of skin with the outside ring made from metal, thereby overcoming metal allergy to allow people having skin sensitive to the metal to wear a metallic ring.
- Furthermore, the inside ring (20) defining the inner diameter of the ring (30) is made of rubber, silicone etc. harmless to human body and may have a plurality of through holes (22) enabling sweat or moisture which may remain on the finger with the ring (30) worn thereon to be easily discharged/evaporated by ventilating action.
- Furthermore, as illustrated in
FIG. 5 , the viewing holes (13) penetrating the outside ring (10) from its outer circumferential surface to inner circumferential surface are formed along the outer circumferential surface, whereby the ventilation action is enhanced and the inside ring (20) can be seen from the outside as well. - In this connection, by coloring the inside ring (20) with a variety of colors to mount it on the inner circumferential surface of the outside ring (10), the colored inside ring (20) can be seen through the viewing holes (13) of the outside ring (10) and thus more pronounced esthetic feeling can be presented.
- Furthermore, the inside ring (20) may has a function of enhancing the health of human body by containing minerals emitting anions or far-infrared radiation (silver, tourmaline, charcoal, ceramic, jade, magnet etc.). Before the inside ring (20) made of rubber or silicone is formed, the minerals are mixed in the form of powder with the rubber or silicone to form the inside ring (20), and thus this inside ring (20) can have a function of emitting anions or far-infrared radiation. Alternatively, the minerals emitting the anions or far-infrared radiation (silver, tourmaline, charcoal, ceramic, jade, magnet etc.) is processed in a pre-determined form and is then plurally joined on the inner circumferential surface or circumferential edges of the inside ring (20), whereby decoration effect and a function of emitting the anions or far-infrared radiation can be provided to the inside ring.
- Therefore, with the above-described construction, any person having an allergy to metal whose skin is sensitive to metal can also wear the ring without any worry as allergy reaction to metal never occurs since the outside ring (10) made from the metal and the skin sensitive to the metal are spaced apart from each other by the non-metallic inside ring (20).
- Moreover, the inside ring (20) may have pigment of various colors incorporated therein or be painted with various colors, thereby exhibiting a color conforming to consumer's taste, and marks, logs, initials, text etc. may be expressed in intaglio or relief on a surface of the inside ring (20).
- Furthermore, a curved portion protruded outward is formed on the inner circumferential surface of the inside ring (20), thereby minimizing frictional resistance between the finger and the inside ring (20) when the ring is worn on or released from the finger. A protrusion degree of the curved portion may be differently set depending on the dimension of inner diameter.
- In other words, for greatly reducing the inner diameter of the ring (30), the inside ring (20) with the curved portion greatly protruded is inserted in and coupled to the outside ring (10), while for relatively insignificantly reducing the inner diameter, the inside ring (20) with the curved portion relatively insignificantly protruded is inserted in and coupled to the outside ring (10).
- Furthermore, a curved portion bent inward is formed along the outer circumferential surface of the inside ring (20), and thus an air gap (21) is formed on an inner side by the curved portion when the inside ring (20) is inserted in the coupling groove (11), thereby providing a buffering action and preventing external physical shock from being transferred to the finger.
- Furthermore, pressing grooves (23) are formed on inner circumferential edges of the inside ring (20), which grooves are compressed when the inside ring (20) is released from the outside ring (10), and thus the inside ring (20) is bent toward one side to thereby easily depart from the coupling groove (11).
- In this connection, the pressing grooves (23) may be plurally formed on the inner circumferential edges of the inside ring (20) at a constant interval or may be continuously formed along the inner circumferential edges.
- Furthermore, as illustrated in
FIG. 3 , embossed parts (24) are formed on the inner circumferential surface of the inside ring (20) to reduce the frictional resistance when the ring is worn on or released from the finger and minimize contact area between the finger and ring, whereby ventilation can be easily achieved and thus sweat or moisture remaining on the finger can be easily evaporated. - Furthermore, according to another example of the present invention, the through holes (22) and embossed parts (24) may be formed alternately on the inner circumferential surface of the inside ring (20), whereby the ventilation may be achieved and a massaging effect on the finger by the embossed parts (24) may be provided as well.
- In addition, as illustrated in
FIG. 6 , the inside ring may be constructed in the form of mesh(net) whereby the contact between the inside ring and the skin is minimized and thus the function of evaporating the sweat or moisture remaining on the finger can be enhanced. - Furthermore, in the case of the ring according to the present invention, the inside ring (20) can be easily separated from the outside ring (10), thus by separately washing only the inside ring (20) with water, hygienic wearing of the ring is possible.
- As illustrated in
FIGS. 2 a to 2 h, the present invention is applicable to various types of rings such as plain ring, man's ring, wedding ring, stone ring etc. - Therefore, only by coupling the inside ring (20) to the outside ring (10) according to the present invention, the ring (30) snugly fitting the finger can be worn, and thus the ring is prevented from easily rotating about the finger and easily coming off the finger to be lost.
- Furthermore, even if the finger and its joint have some difference from each other in thickness, the difference can be overcome, thereby providing a ring excellent in wearability.
- As above, the present invention has been illustrated and described with respect to preferred examples of the present invention, but the present invention is not limited to the above-described examples and various modifications may be made without departing from the spirit of the invention as defined by the claims of the present invention, and such modifications also fall within the claims.
- In the inner diameter-adjustable ring according to the present invention, the coupling groove is formed on the inner circumferential surface of the outside ring with an outer diameter of constant dimension and the inside ring is inserted in the coupling groove, therefore, an advantage is obtained that in the case where change of dimension of the inner diameter of the ring is large, a consumer can enlarge or reduce the inner diameter of the ring only by replacing the inside ring in person, thus industrial applicability is present.
