Inside diameter-adjustable ring

Abstract

The present invention pertains to an inside diameter-adjustable ring in which the inside diameter of the ring is adjustable, and more specifically, to an inside diameter-adjustable ring which comprises: an outside ring which has coupling grooves formed along the inner surface thereof; and an inside ring which is inserted into said coupling grooves and forms the inside diameter of the ring, wherein: separation prevention ridges are formed in the coupling grooves of said outside ring in order to prevent the inserted inside ring from being taken out; a curved portion which is bent to the inner side is formed along the outer surface of said inside ring, so that an air gap is formed on the inner side by the curved portion when said inside ring is inserted into the coupling grooves; a plurality of holes are formed on said inside ring; minerals which emit anions and far-infrared radiation are contained in said inside ring, and embossed parts are formed on the inner surface of said inside ring such that a consumer is able to extend or reduce the inside diameter of the ring by directly changing only the inside ring if the inside diameter of the ring has a huge difference in size; since said inside ring is made of an elastic rubber or silicon material, a certain change in the degree of size is available even with elasticity thereof without changing said inside ring; physical shock applied from the outside is absorbed into the inside ring by an air cushion generated by said inside ring, whereby a finger on winch the ring is worn is protected; the plurality of holes are formed on said inside ring in such a manner that sweat or moisture which remains between the finger and the ring is evaporated through the holes; and since the minerals which emit the anions and the far-infrared radiation are contained, the invention has a health enhancement function.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of Korean Patent Application No. 10-2010-0061020, filed on Jun. 28, 2010 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to an inner diameter-adjustable ring where the inner diameter of the ring can be adjusted, more particularly, an inner diameter-adjustable ring that comprises an outside ring which has a coupling groove formed along the inner circumferential surface thereof, and an inside ring which is inserted in the coupling groove and defines an inner diameter of the inner diameter-adjustable ring, wherein separation prevention ridges are formed in the coupling groove of the outside ring in order to prevent the inserted inside ring from coming off the groove, and a curved portion bent inward is formed along an outer circumferential surface of the inside ring, so that an air gap is formed...

AI Technical Summary

Benefits of technology

The present invention allows for easy adjustment of the inner diameter of a ring, making it simple for consumers to change the size of their rings. The inside ring is made of elastic rubber or silicone, which can absorb physical impact and protect the finger with the ring. Additionally, the inside ring has multiple through holes that help evaporate sweat or moisture, preventing skin contact with the outside ring, which can cause allergic reactions. The inside ring also contains minerals that release anions or far-infrared radiation, providing health benefits.

Problems solved by technology

However, such conventional ring has a problem that since it is standardized in dimension of its inner diameter for its characteristic, it cannot cope with the change of the thickness of the fingers according to the increased or decreased amount of the weight of user, therefore, if the finger becomes thicker the ring may not be worn and if the finger becomes slimmer the ring may idly rotate or easily come off the finger to be lost.

Furthermore, since conventional ring is produced with standardized dimension, for people having thick joints of fingers, the ring worn barely becomes loose on the finger, thus the wearability of the ring is not good, while for people having slim joints of the fingers, the ring is easily worn, thereby exhibiting a good wearability, but it is concerned that the ring may easily come off the finger to be lost.

However, those solutions have problems that their structures for varying the inner diameter are complex and cannot be applied to various types of rings and devices for varying the inner diameter may be broken due to external physical impact, thereby causing an injury to the finger and a period of time for production is much consumed and production cost per unit is also high.
