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.

Description
PRIORITY STATEMENT
[0001] 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
[0002] 1. Field of the Invention
[0003] 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.
[0004] 2. Description of Related Art
[0005] 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.
[0006] A ring could not be presented to any one without knowing
his/her exact size. Accordingly exchanges or further modification
is necessitated.
SUMMARY
[0007] 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: [0008] a) Ring automatically
adjusts itself on different sizes of finger. [0009] b) Due to
change in blood pressure there is a tendency of fingers to swell,
the ring adjusts accordingly to provide comfort. [0010] c) The ring
could be presented to any one without modification e.g. from
grandmother to mother and granddaughter and so on.
[0011] 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.
[0012] 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
[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.
