Abstract
An adjustable ring is provided which consists of pivotally linked sections. One section is made of two telescopically engaged parts. One of these parts includes holes. The other part includes an axially displaceable element mounted on a pivotal segment of a decorative structure of the ring for engaging in the holes.
Claims20
An adjustable article of jewelry comprising:
- four to six sections;
- and
- connecting means for pivotally connecting said sections in a closed geometrical form, said geometrical form defining an opening and an axis through said opening,
- wherein one of said sections includes first and second parts in extension of one another for assuming different relative positions which establish effective lengths of said one of said sections, and locking means for releasably holding said parts in at least a selected one of said relative positions, whereby said parts in said selected one of said relative positions establish a selected size for said closed geometrical form, and
- wherein said locking means includes a sequence of side-holes spaced on one outside of one of said parts, and being located axially relative to said axis of said closed geometrical form, and an element on an outside of the other of said parts, said element being displaceable at least in a substantially axial direction relative to said axis of said closed geometrical form to engage in a selected one of said side-holes to lock said parts together in said selected one of said relative positions.

In a method of forming a ring of adjustable size, the improvements comprising:
- forming four to six arcuate sections, wherein the forming of one of the sections includes forming two telescopically engaged parts one of which is a tongue and the other of which is a sleeve;
- inserting the tongue in the sleeve and pivotally connecting the sections together to form a ring defining an axis therethrough, the pivotal connecting of the segments enabling the tongue to move readily within the sleeve;
- forming axially extending spaced side-holes on an axial outside, relative to the axis of the ring, of one of the parts and an axially displaceable, relative to the axis of the ring, element on an outside of the other of the parts, the element being for locking the tongue in an adjusted position by axially displacing, relative to the axis of the ring, the element into a selected one the side-holes;
- and displacing the element into a selected one of the side-holes;
- whereby to provide the ring with an adjustable size.
