Ring-Shaped Piece of Jewelry Having an Adjustable Inner Diameter
First Claim
1. A piece of jewelry, of substantially annular shape, including first and second parts, the profiles of which have respective shapes substantially of portions of a ring and having respective first and second ends, said first and second parts being connected to each other by a pivot type connection, each of said first and second parts having a first of its ends adapted to cooperate with a first end of the other part, by nesting of variable depth, to define a closed ring of adjustable inner diameter, at least one spring member being adapted to act on both parts so that their first ends tend to nest one within the other to reduce said inner diameter,said pivot type connection being at a distance from the second end of said first part, said first part having an overlap portion, located between said pivot type connection and said second end, of greater radius than an inner portion of said second part facing which said overlap portion is located, so as to overlap said inner portion at least partly.

Abstract
A piece of jewelry is disclosed, which has an adjustable inner diameter, includes first and second parts, in the form of portions of a ring and having respective first and second ends, the first and second parts being connected to each other by a pivot type connection. Moreover, each of the first and second parts has a first of its ends adapted to cooperate with a first end of the other part, by nesting of variable depth, to define a closed ring of adjustable inner diameter. At least one spring member is adapted to act on both parts so that their first ends tend to nest one within the other to reduce the inner diameter of the piece of jewelry. The pivot type connection is at a distance from the second end of the first part, the latter having an overlap portion, located between the pivot type connection and the second end, of greater radius than an inner portion of the second part facing which it is located, so as partly to overlap it.
