发明名称 Expandable ring design and method for making same
摘要 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.
