| 摘要 |
<p>The invention relates to a piece of jewellery and a method for the production thereof, based on simple, competitive, reproducible technology, without using additional parts or any special tools for a rapid and simple assembly, enabling at least one indexed position to be created between rotating rings which can be adjacently arranged or superposed, the number of said rings being unlimited. Said circular piece of jewellery (1) comprises an inner ring (2) and three adjacent external rings (3-5) which are freely mounted in a coaxial manner on the inner ring (2) in order to rotate in relation to each other. The edges of the external rings (3-5) are provided with indexing means (7) for fixing the external rings in at least one indexed position. Said indexing means (7) consist of indexing notches (71) provided in the central ring (4) and indexing fingers (71) provided in the other rings (3, 5). Each indexing finger (71) is provided at the end of a flexible tongue (72) machined directly in the ring so that it is mobile 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 enables a relative rotation of said rings (3-5).</p> |
