Device for connecting precious elements or the like to finger rings

Abstract

A device for connecting precious elements to finger rings, comprising a substantially annular body (known in the specific field as a shank), to be worn on a finger, and a gem holder, which is connected to the substantially annular body in an upper region. The substantially annular body has at one point thereof a head, which is integral therewith and is inserted in and mated with a lower portion of the gem holder by way of a bayonet coupling.

1 . A device for connecting precious elements or the like to finger rings, comprising a substantially annular body (known in the specific field as a shank), to be worn on a finger, and a gem holder, which is connected to said substantially annular body in an upper region, characterized in that said substantially annular body has at one point thereof a head, which is integral therewith and is inserted in and mated with a lower portion of said gem holder by way of a bayonet coupling. 
     
     
         2 . The device according to  claim 1 , wherein said head, once inserted, is rotatable about a rotation axis which is substantially parallel to the mating direction, and in that said head comprises three portions in succession:
 a lower portion, which is substantially disk-like and forms an upper surface for mating with a part of said lower portion of said gem holder,   an intermediate portion the shape and dimensions of which are such that it cooperates to define parts of the bayonet coupling,   an upper portion which is plate-like and substantially oval.   
     
     
         3 . The device according to  claim 2 , wherein said three portions constitute a monolithic body with each other and with said substantially annular body. 
     
     
         4 . The device according to  claim 2 , wherein said lower portion of said gem holder is hollow for the insertion of said head and comprises three regions:
 a lower region, which has a circular opening for the passage of said upper portion of said head and is adapted to accommodate the lower portion of said head during the mating of said head with said lower portion of said gem holder,   an intermediate region, which has an opening, also for the passage of said upper portion of said head, which is reduced with respect to said circular opening of said lower region, defining two protrusions which are diametrically opposite for preventing the escape of said head from said gem holder when said head is rotated with respect to the insertion,   an upper region, which has a circular opening with two recessed shoulders, said shoulders defining in the receptacle of said upper portion of said head the stroke limit of the rotation of said head with respect to said gem holder.   
     
     
         5 . The device according to  claim 4 , further comprising locking means which are adapted to prevent the opposite rotation of said head in relation to said gem holder. 
     
     
         6 . The device according to  claim 5 , wherein said locking means comprise a plate-like elastic element, which is folded substantially in a Z-like shape and is accommodated in a through cavity which is shaped conveniently to accommodate said elastic element and is defined in said upper portion of said head, said elastic element protruding from the through cavity up to said intermediate region at its two ends, for the interlocking coupling of each one of said two ends thereof within recesses formed on the riser of said opening of said intermediate region at the end of rotation. 
     
     
         7 . The device according to  claim 1 , wherein said gem holder is provided, in an upper region, with a seat for gems or the like. 
     
     
         8 . The device according to  claim 4 , wherein said regions of said lower portion of said gem holder are obtained from a same element.
