Adjustable Circumference Finger Ring
BACKGROUND OF THE INVENTION
I) FIELD OF THE INVENTION
The invention herein relates to linger rings, specif cally an adjustable
circumference finger ring capable of being pivoted apart and, furthermore,
varied
in circumference.
2) DESCRIPTION OF THE RELATED ART
Finger rings are currently the most commonly observed type of ornamental
_jewelry and in order to firrther attract consumers with a newer varieties,
many
manufacturers are focusing of breakthroughs in exterior appearance and
minimizing ring wearing problems. '1"he most typical problem is that finger
diameter and the l3xed circumference of annular band do not match, resulting
in
easy loosening or wearing difficulty. The approach usually used by
manufacturers
to solve this problem is to produce a same model finger ring in a range of
different
circumferences for wearer selection. As a result, finger ring production cost
is
higher and does not meet the requirements of economic advantage. Another
approach is to design the annular band of the finger ring in a expandable
arrangement and thereby utilize the material of the annular band to fabricate
a
CA 02393992 2002-07-18
finger ring that accommodates fingers of differing diameters. I-iowever, since
such
annular bands tend to contort, an appealing circular shape cannot be
maintained.
SUMMARY OF THE INVENTION
The primary objective of the invention herein is to provide an adjustable
circumference finger ring in which the user can wear and remove the finger
ring
without sliding it past the finger joint and wherein the circumference of the
finger
ring is adjustable to accommodate finger diameter to thereby increase wearing
comfort and prevent the dislodging of the finger ring.
'hherefore, the technological means to achieve the said objectives of the
invention herein includes: the finger ring is comprised of two semicircular
members and a tlexile linkage structure that couples one extremity of the two
semicircular members such that the two semicircular members can be spread
apart,
with the two semicircular members and having a circumference adjustment
structure disposed at their opposite extremities that enables the
circumferential
variation of the finger ring as required to accommodate the finger diameter of
the
wearer.
