ADJUSTABLE RING

Abstract

An adjustable finger ring may include a ring head having through holes on the bottom a first shank having shank collars as support at one end and a split portion at the other end, and a second shank having shank collars as support at one end and a split portion at the other end. The split portions may complement and overlap each other in an operative condition of the ring. A spring can be fitted inside the two supports with the coils of the spring aligned with the holes of the support of the first shank so as to allow a pin to pass through. The inward facing surfaces of the collars of the second shank may confront the outward facing surfaces of the collars of the first shank. The holes of the collars can be aligned so as to allow the pin to pass through. The two shanks may be hinged together and act as a spring clasp.

Claims

1. An adjustable finger ring comprising: a ring head having through holes; a first shank having a pair of first shank collars at one end and a first split portion at the other end; a second shank having a pair of second shank collars at one end and a second split portion at the other end; wherein the first and the second split portions overlap each other; a spring situated between the first shank collars and between the second shank collars, such that inward facing surfaces of the second shank collars confront outward facing surfaces of the first shank collars, and inward facing surfaces of the first shank collars confront the spring; a pin extended through the through holes of the ring head, the first shank collars, the second shank collars, and coils of the spring; wherein the first and the second shanks are hinged together for pivot action about the pin, such that the first and the second split portions are slidable over each other; and wherein the spring influences the first and the second shanks to pivot about the pin in a closing direction.

2. An adjustable finger ring as claimed in claim 1, wherein the ring head is fabricated from silver; wherein the first and the second shanks are fabricated from silver; wherein the pin is fabricated from silver; and wherein the spring is fabricated from steel.

3. A method of making an adjustable finger ring, the method comprising: inserting a coil spring between two first collars of a first shank; aligning the coils of the coil spring with holes provided in the first collars; positioning a second shank having two second collars such that inward facing surfaces of the second collars confront outward facing surfaces of the first collars; aligning holes provided in the second collars with the holes in the first collars; positioning a ring head with through holes, such that the through holes are aligned with the holes in the second collars; inserting a pin through the through holes of the ring head, the holes in the second collars, the holes in the first collars, and the coils of the coil spring; and fixing ends of the pin to a bottom of the ring head.

DESCRIPTION OF NON-LIMITING EMBODIMENTS

[0021] With reference to FIGS. 1 and 2, an adjustable finger ring includes a ring head (1) having through holes (20) on the bottom. The ring head (1) is supported by a first shank (2) and a second shank (5). Turning to FIG. 7, the first shank (2) has shank collars (6a) as support at one end and a split portion (6b) at the other end. The second shank (5) has shank collars (7a) as support at one end and a split portion (7b) at the other end. As shown in FIGS. 5 and 6, the split portions (6b) and (7b) complement and overlap each other in an operative condition of the ring.

[0022] A spring (4) is fitted between the collars of the shanks (2) and (5). The coils of the spring (4) are aligned with the holes of the collars (6a) and (7a). And a riveting pin (3) extends through the pair of collars (6a), the pair of collars (7a), and the coils of the spring (4). The collars (7a) of the second shank (5) are spaced apart farther than the collars (6a) of the first shank (2). Thus, the inward facing surfaces of the collars (7a) confront the outward facing surfaces of the collars (6a), and the inward facing surfaces of the collars (6a) confront the spring (4). It will be appreciated that in the assembled condition, one end of the spring (4) presses against the collared end of the shank (2), and the other end of the spring (4) presses against the collared end of the shank (5).

[0023] By virtue of the riveting pin (3), the two shanks (2) and (5) are hinged together and act as a spring clasp. The spring (4) influences the shanks to rotate about the pin (3) in a closing direction to the condition shown in FIG. 2, in which the split portions (6b) and (7b) interact to limit the movements of the shanks in the closing direction. If the shanks are rotated about the pin (3) in an opening direction and against the influence of the spring (4), then the overlapped split portions (6b) and (7b) of the shanks will slide over each other and widen, which results in an increased size of the ring. If one reduces this pressure, then the spring (4) will influence the shanks to rotate about the pin (3) in a closing direction and regain the original position shown in FIG. 2.

[0024] By way of example only, the material chosen for the different parts may be as given below:

TABLE-US-00001 Description Material Ring Head (1) Silver Shank (2) Silver Riveting Pin (3) Silver Coil spring (4) Hardened steel Shank (5) Silver

[0025] The method of making an adjustable finger ring may involve the following. Insert the coil spring (4) between the two collars (6a) of the first shank (2), and align the coils of the spring (4) with the holes of the collars (6a).

[0026] Position the second shank (5), such that the inward facing surfaces of the collars (7a) confront the outward facing surfaces of the collars (6a), and align the holes of the collars (7a) with the holes of the collars (6a). This will complete stage two of the assembly.

[0027] Position the ring head (1) on the top of the assembly, as shown in FIG. 4. And align the through holes 20 with the holes in the collars (7a). This will complete stage 3 of the assembly.

[0028] Insert the pin (3) through the entire assembly and solder both ends of the pin on the through holes (20). In the assembled condition, both ends of the pin (3) are fixed at the bottom wall of the ring head (1).

[0029] The present invention is not limited to the above-described embodiments, and various alterations, modifications, and/or alternative applications of the invention may be possible, if desired, without departing from the scope and sprit of the invention, which can be read from the claims and the entire specification. All of these possible alterations, modifications, and/or alternative applications of the invention are also intended to be within the technical scope of the present invention.
