Elements for trinkets

Abstract

The invention relates to a modular element (1) for making jewelry items, trinkets and the like, having a convex outer surface (11) and a through hole (14) arranged at the top of said outer surface (11), wherein a wire, chain or support for making said jewelry item, trinket and the like, can be inserted through said through hole (14), a main axis of symmetry (X) passing through the hole (14), comprising a concave inner surface (12) intended to at least partially accommodate the outer surface (11) of a second element (1) adjacent to the first one, characterized in that said outer surface (11) can be inscribed on a rotation surface whose generatrix is an arc of a conic section and whose axis of rotation coincides with said main axis of symmetry (X).This invention also relates to a jewelry item (100).

1 . A modular element for making jewelry items, trinkets and the like, having
 a convex outer surface,   a through hole arranged at the top of said outer surface, through which a wire, chain or support for making said jewelry item, trinket and the like, can be inserted,   a main axis of symmetry (X) passing through the hole,   a concave inner surface intended to at least partially accommodate the outer surface of a second element adjacent to the first one,   wherein the outer surface can be inscribed in a rotation surface whose generatrix is an arc of a conic section and whose axis of rotation coincides with said main axis of symmetry.   
     
     
         2 . The modular element according to  claim 1 , wherein said conic section is a circumference, an ellipse or a parabola. 
     
     
         3 . The modular element according to  claim 2 , wherein said main axis of symmetry coincides with the axis of symmetry of the parabola. 
     
     
         4 . The modular element according to  claim 2 , wherein said main axis of symmetry coincides with one of the axes of symmetry passing through the center of symmetry of the ellipse. 
     
     
         5 . The modular element according to  claim 4 , wherein said rotation surface is a spheroid, and
 in that the ratio between the major axis and the minor axis of said spheroid is approximately 0.5.   
     
     
         6 . The modular element according to  claim 5 , wherein said element extends, along the direction parallel to the major axis of said spheroid, for a length equal to about 7/16 of said major axis. 
     
     
         7 . The modular element according to  claim 2 , wherein said main axis of symmetry coincides with one of the diameters of the sphere. 
     
     
         8 . The modular element according to  claim 7 , wherein said rotation surface is a portion of sphere comprised between said hole and a plane perpendicular to an axis (j) of said hole and located at a distance from the center of said sphere equal to 3/16 of the diameter (d) thereof. 
     
     
         9 . A jewelry item, comprising
 a plurality of modular elements according to  claim 1 , and   a support, such as a wire, chain or the like, inserted in the through holes of each of said modular elements,   wherein a convex portion of said outer surface of each of said elements is at least partially inserted in a concave portion of said inner surface of an adjacent element.
