The disclosure relates to a ring structure with an adjustable size, which includes an outer ring, an inner ring, and a concave-convex structure. The outer ring has an inner wall. The inner ring is removably fitted inside the outer ring and has an outer wall abutting against the inner wall. The concave-convex structure includes a protrusion connected on either one of the inner wall of the outer ring and the outer wall of the inner ring and a slot disposed on another one of the inner wall of the outer ring and the outer wall of the inner ring. The protrusion is mortised in the slot. Therefore, the inner ring is removably fitted inside the outer ring to generate a ring with various sizes for different users. The ring structure of this disclosure may have the advantages of providing various sizes and saving costs.

The present invention refers to the field of precious objects, and in particular to the field of goldsmithing, jewelery, with particular reference to rings. It should be noted that the present invention can also refer to the field of bijoux or the like. Particularly interesting for the present invention are the rings and the problem of their measures.

A jewelry apparatus can include a base member having a hippocrepiform configuration, the base member having a first prong and a second prong. The jewelry apparatus can include a coupling member operably configured for attachment to the base member. The coupling member can include a disk member having a first side and a second side, the first side having a first set of indicia depicting a first partial portion of a word, the second side having a second set of indicia depicting a second partial portion of the word, a first projection extending from the disk member operably configured for attachment to the first prong and a second projection extending from the disk member operably configured for attachment to the second prong. The coupling member is configured to rotate such that the first set of indicia and the second set of indicia create the visual appearance of the word.

The present disclosure provides a ring adjuster. The ring adjuster includes an adjuster main body, at least one locking structure, a first side wall and a second side wall. The adjuster main body is arc-shaped, the first side wall and the second side wall are connected with two opposite sides of the adjuster main body respectively. The adjuster main body includes an inner surface and an outer surface, the inner surface is configured to contact with a user's finger, the outer surface is configured to contact with a ring. The locking structure crosses the first side wall and the second side wall such that a locking chamber is formed between the outer surface and the locking structure to contain the ring.

One or more ring re-sizing attachments are appended to the internal circumference of a ring band so that a ring band large enough to pass over a knuckle remains comfortably fit around the finger below the knuckle. Each attachment includes a base defining an internal volume surrounded by a raised wall. A button slidingly engaged in the base internal volume defines an inner volume, and one or more springs are held in the button inner volume. As the one or more springs are compressed, the button moves into the internal volume of the base, increasing the space within the band to move the band beyond a knuckle. Once the band is beyond the knuckle, the spring(s) urge the button upwardly, causing the lips of the button to contact ledges or lips projecting from the sidewall of the base, to tighten the fit of the ring band around the finger.

A ring type wearable terminal is provided with a ring and a communication unit that is housed in the ring. The communication unit is provided with a ring-shaped flexible substrate. The flexible substrate is provided with a bonding portion formed such that the bonding portion can be bonded at a plurality of different positions in a longitudinal direction in accordance with the size of the ring. By changing a bonding position of the bonding portion, the diameter of the flexible substrate formed in a ring shape can match the size of the ring. Thereby, a single flexible substrate can be used for a ring of multiple sizes, and an increase in the manufacturing cost when offering a size range of multiple sizes can thus be prevented.
