Circular piece of jewelry is rotating rings indexes and its method of manufacturing

摘要

The present invention relates to a piece of jewelry, and its manufacturing process based on a simple technology, competitive, reproducible, without the addition of a part, offering a rapid assembly and simple, making it possible to create one or a plurality of indexed positions between the rings, the number of rings or not being limited, these rings may be juxtaposed or superposés.le piece of jewelry (1) comprises a circular inner ring (2) and three external rings (3 - 5) which are juxtaposed, freely mounted coaxially on the inner ring (2) to rotate with respect to the other.

These indexing means (7) comprise indexing notches (70) provided in the central ring (4) and an indexing finger (71) provided in the other rings (3, 5). Each indexing finger (71) is provided at the end of a flexible tongue (72) is machined directly in the ring to be movable between a projecting position in which it is housed in an indexing notch (70) and locks the relative position of the rings (3 - 5), and a retracted position in which it allows a relative rotation of these rings (3 - 5) .application: jewelry, jewelry, clock and watch-making, gold, accessories, etc.
