Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and inclusion in this section is not an admission that it is prior art.

Generally, rings are manufactured to fit the wearer's finger size. Since the inner diameter of the ring is fixed, the ring does not fit the user's finger often when the size of the finger fluctuates as the user's weight is excessively reduced or increased.

In addition, there is a problem that users who have good fingers feel an uncomfortable fit as the dimensions of their fingers suddenly increase.

Accordingly, there is a growing need for a functional ring that can be easily attached and detached while providing a comfortable fit to the user even when the size of the user's finger fluctuates.

Rings for adjusting the size are disclosed in conventional literatures, but all of the rings disclosed in the literatures have a separable structure or a structure for adjusting the size permanently protrudes from the inside of the ring. Rings disclosed in prior literature have a problem in that a structure for adjusting the size can be easily identified externally, which acts as a factor in deteriorating aesthetics, which is the original function of the ring.

Therefore, the pressing part 322 is pressed outward in the radial direction of the ring 300 by the restoring force of the elastic member 324 to return to its original length. Through this, the pressing part 322 protrudes out of the adjusting part housing 323 without attaching the expansion part 321 to the adjustment part housing 323 using an adhesive material or attaching the pressing part 322 to the expansion part 321. It may not be.

In the case of using an adhesive material, the expansion part 321 may be damaged in the process of repeatedly expanding the expansion part 321. On the other hand, in the process of repeatedly expanding the expansion part 321 when the adhesive material is not used, The risk of damage is significantly reduced. That is, durability of the expansion part 321 may be improved by disposing the elastic member 324 . As a result, durability of the ring 300 may be improved by disposing the elastic member 324 .

The size adjusting unit 420 is formed in the same number as the number of mounting grooves 410a. In one embodiment, the mounting groove 410a may be recessed in a size corresponding to that of the size adjustment unit 420 . For example, in a state in which all of the size adjustment units 420 are inserted into the mounting grooves 410a, the size adjustment units 420 may not protrude from the inner surface of the body unit 410.

The size adjustment unit 420 includes an expansion unit 421 , a pressurization unit 422 and an adjustment unit housing 423 .

In addition, a housing engaging portion 4231 is protruded from a portion of the first inner space that is open to the inside of the ring 400 . Accordingly, in the adjustment unit housing 423, the width of the ring 400 in the circumferential direction is relatively short in the portion where the housing hooking portion 4231 is formed compared to other portions. In addition, the housing locking portion 4231 prevents the pressing portion 422 from completely separating from the adjusting portion housing 423 . In one embodiment, the adjustment unit housing 423 may be formed of various plastic materials having relatively high thermal insulation properties. In one embodiment, the adjustment unit housing 423 may be formed of a known plastic material that is not damaged at a temperature of 50°C.

Through this, the pressing part 422 can be inserted again to return to the original ring design.

In one embodiment, the reference temperature may be 20 ℃. However, it is not limited thereto.

As the power-off thermoelectric element 429 does not generate thermal energy, the inside of the expansion unit 421 is cooled, and the gaseous material expanded in the internal space of the expansion unit 421 may be liquefied. Accordingly, the pressing portion 422 protruding to the inside of the ring 400 may be inserted toward the outer side in the radial direction of the ring 400 again.

The pressing part 422 may be formed in a shape corresponding to the first inner space of the adjusting part housing 423 . In one embodiment, the pressing portion 422 may be formed in a form in which a pressing portion locking portion protrudes from one side of the hexahedron toward the circumferential direction of the ring 400. Accordingly, in the process of protruding the pressing part 422 due to the expansion of the expansion part 421, the holding protrusion of the pressing part is caught by the housing holding part 4231, and the pressing part 422 is separated from the adjusting part housing 423. can prevent it from happening.
