#CMT# #/CMT# The assembly (S) has two cylindrical rings (10, 20) with different inner diameters (a, b). Peripheral parts (11, 21) of the rings are raised and their diameter are increased in order to create a widened configuration, where the rings have larger diameter in the peripheral parts than in central parts (12, 22). External diameters of the respective peripheral parts of the rings have equal dimensions so that peripheral edges of the parts are placed in contact with one another without leaving a space in between them, where the peripheral parts are grooved. #CMT#USE : #/CMT# Used for assembling a pair of rings e.g. betrothal ring, marriage ring, better friends ring, and parent and child ring e.g. mother and daughter ring and father and daughter ring. #CMT#ADVANTAGE : #/CMT# The external diameters of the peripheral parts of the rings have equal dimensions so that peripheral edges of the parts are placed in contact with one another without leaving the space in between them, thus constituting an identical homogeneous systematic ornament to offer the construction of a single piece when a single person carries a pair of rings side by side, and hence improving unity in the shape of rings and usage value of the rings. The peripheral edges of the rings, which are in contact with each other, are grooved to prevent the rotation of rings with each other and to improve the assembly of the rings. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a ring pair assembly. a, b : Inner diameters S : Ring pair assembly 10, 20 : Rings 11, 21 : Peripheral parts 12, 22 : Central parts. |
