  • Ring having two parts that can be displaced relative to one another
    Patent number: 7266977
    Abstract: The ring has at least two mutually rotatable parts, with a detent mechanism for respectively one of two mutually rotatable parts, and securing means. For improving the detent mechanism and the substantially play-free retention the detent mechanism is respectively provided in the intersecting plane (S) of two mutually rotatable parts and the mutually rotatable parts are secured by at least one springable element. Furthermore, if marks are provided on the surfaces of the ring, the most varied appearances can be altered and obtained by rotating one of the parts. This applies particularly if the surfaces of the parts are not even but wave-shaped.
