Item of jewelry with changeable decoration

Abstract

The invention relates to an item of jewelry comprising a support bezel ( 3 ) for stones or other decorative motif, characterised in that said support bezel ( 3 ) is overlapped by an ornamental piece ( 4 ) arranged to hide only certain parts ( 5 ) of the stones and/or decorative motif on the bezel. The above is provided with a means for pivoting about a vertical axis with respect to the support face of the bezel ( 3 ) and for the automatic locking thereof with each rotation of the piece ( 4 ). The above finds application in rings or similar.

1 . The piece of jewelry consists of a supporting setting ( 3 ) of stones and or any other decorative designs, characterized in that the supporting setting ( 3 ) is surmounted by an ornament ( 4 ) shaped so that it hides only certain parts ( 5 ) of the stones and/or of the decorative design of the setting ( 3 ) and fitted with a mechanism which allows it to pivot about the axis perpendicular to the face of the setting ( 3 ) as well as to lock automatically at each stage of the piece's rotation ( 4 ).  
   
   
       2 . The piece of jewelry, in particular the ring, according to  claim 1 , is characterized in that the supporting setting ( 3 ) is fitted with stones and/or design so that the size and shape of each sector is similar to each of the protruding parts ( 6 ) of a central ring ( 7 ) which composes the ornament ( 4 ).  
   
   
       3 . The piece of jewelry, according to  claim 2 , is characterized in that the ornament ( 4 ) is fitted with at least one protruding part ( 6 ) so as to hide at least one of the sectors ( 5 ) that are arranged in a regular way about the setting ( 3 ).  
   
   
       4 . The piece of jewelry, according to claims  2  or  3 , is characterized in that the protruding parts ( 6 ) of the ornament ( 4 ) are fitted with stones and/or ornamental designs.  
   
   
       5 . The piece of jewelry, according to any of the proceeding claims, is characterized in that the mechanism of pivoting and automatic locking is advantageously composed of an axis formed, for example, of a notch ( 8 ) situated at the center of the ornament ( 4 ), of a bolt ( 9 ), of an elastic element ( 10 ) intended to fasten the ornament ( 4 ) to the setting ( 3 ), and of a locking system to stop the rotation at each sector composed of a notch ( 11 ) and of juxtaposed slopes ( 12 ) arranged on the setting ( 3 ) and work using “V”-shaped ridges of the ornament ( 4 ) that are able to seat themselves into a notch ( 11 ), and, under the force of the elastic element ( 10 ), stop rotation.  
   
   
       6 . The piece of jewelry, according to claims  1  through  4 , is characterized in that the pivoting and locking mechanism of the ornament ( 4 ) consists of two cylindrical pieces ( 13 ) and ( 14 ) mounted coaxially, one of which ( 13 ) is attached to the setting ( 3 ), the other ( 14 ) attached to the ornament ( 4 ), and both axially fixed by a clip ( 15 ) such that the free rotation of one ( 14 ) of the cylindrical portions relative to the other ( 13 ) is resisted by the presence of an elastic element ( 16 ) protruding from the body of the cylindrical portion ( 14 ) of the ornament ( 4 ) so that it is seated ( 17 ) onto each sector ( 5 ) of precious stones and/or design of the setting ( 3 ).
