Abstract

An expandable jewelry ring. The ring has a split circular spring made of springy metal and having first and second ends separated by a gap. A tongue portion extends from the first end of the spring and into the gap. A mounting is made of metal and has a generally split circular shape with first and second ends separated by a gap and having a spring channel formed therein. The spring channel has a first portion and a second portion. The spring is positioned in the first portion of the spring channel, with the tongue portion being slideably moveable in the second portion of the spring channel. When pressure from a wearer's finger is exerted on the inside of the mounting, it will expand the effective size of the ring, and when pressure is relieved, the ring will spring back to its original size.

Dependent claims

An expandable jewelry ring, comprising:

a split circular spring made of resilient material and having a first end and a second end, the first and second ends separated by a spring gap;
a tongue portion extending from the first end of the spring and into the spring gap;
and
a mounting comprising resilient material and having a generally split circular shape with a first end and a second end separated by a gap, a spring channel formed in the mounting, the spring channel having a first portion and a second portion, wherein the spring is positioned in the first portion of the spring channel, the tongue portion being slideably moveable in the second portion of the spring channel and having means to prevent the tongue portion from being completely withdrawn from the second portion of the spring channel, wherein when pressure is placed on the inside of the mounting, it will expand from a first configuration where the first end and the second end of the mounting are separated by a first smaller gap, to a second configuration where the first end and the second end of the mounting are separated by a second larger gap to increase the diameter of the jewelry ring, and when pressure is removed, will contract back to a smaller size.
