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.

PRIORITY STATEMENT

This application claims priority under 35 USC 119(a)-(d) to IN patent application No. 2755/MUM/2015, which was filed on Jul. 21, 2015, the entire content of which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention
This invention relates to the field of Jewellery manufacturing, particularly to a finger ring and more particularly to an adjustable finger ring and the manufacturing of the same.
2. Description of Related Art
It is a common observation that due to change in blood pressure there is a tendency of fingers to swell and the ring requires adjustment accordingly to provide comfort.
A ring could not be presented to any one without knowing his/her exact size. Accordingly exchanges or further modification is necessitated.

SUMMARY

Non-limiting embodiments of the invention may obviate the drawbacks in the prior art. Such embodiments may provide one or more of the following benefits:

- a) Ring automatically adjusts itself on different sizes of finger.
- b) Due to change in blood pressure there is a tendency of fingers to swell, the ring adjusts accordingly to provide comfort.
- c) The ring could be presented to any one without modification e.g. from grandmother to mother and granddaughter and so on.

According to a non-limiting embodiment, 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 may be fitted inside the two supports, such that the coils of the spring align with the holes of the supports to allow a pin to pass through. Here, the inside surfaces of the collars of one shank may confront the outside surfaces of the collars of the other shank, with the holes of the collars aligned so that the riveting pin can pass through, to make an assembly so that the two shanks are hinged together and act as a spring clasp.
According to a non-limiting embodiment, a method of making an adjustable finger ring may involve inserting a coil spring between two first collars of a first shank, and aligning the coils of the coil spring with holes provided in the first collars. A second shank having two second collars may be positioned such that inward facing surfaces of the second collars confront outward facing surfaces of the first collars. Holes provided in the second collars may be aligned with the holes in the first collars. A ring head with through holes may be positioned, such that the through holes are aligned with the holes in the second collars. A pin may be inserted 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. Both ends of the pin may be fixed to a bottom of the ring head.

DESCRIPTION OF NON-LIMITING EMBODIMENTS

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 (6 a) as support at one end and a split portion (6 b) at the other end. The second shank (5) has shank collars (7 a) as support at one end and a split portion (7 b) at the other end. As shown in FIGS. 5 and 6, the split portions (6 b) and (7 b) complement and overlap each other in an operative condition of the ring.
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 (6 a) and (7 a). And a riveting pin (3) extends through the pair of collars (6 a), the pair of collars (7 a), and the coils of the spring (4). The collars (7 a) of the second shank (5) are spaced apart farther than the collars (6 a) of the first shank (2). Thus, the inward facing surfaces of the collars (7 a) confront the outward facing surfaces of the collars (6 a), and the inward facing surfaces of the collars (6 a) 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).
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 (6 b) and (7 b) 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 (6 b) and (7 b) 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.
By way of example only, the material chosen for the different parts may be as given below:


	Description	Material

	Ring Head (1)	Silver
	Shank (2)	Silver
	Riveting Pin (3)	Silver
	Coil spring (4)	Hardened steel
	Shank (5)	Silver

The method of making an adjustable finger ring may involve the following. Insert the coil spring (4) between the two collars (6 a) of the first shank (2), and align the coils of the spring (4) with the holes of the collars (6 a).
Position the second shank (5), such that the inward facing surfaces of the collars (7 a) confront the outward facing surfaces of the collars (6 a), and align the holes of the collars (7 a) with the holes of the collars (6 a). This will complete stage two of the assembly.
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 (7 a). This will complete stage 3 of the assembly.
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).
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.
