Foldable Ring

Abstract

A foldable ring includes a main ring and a flipper. The main ring has a first inner peripheral surface, a first outer peripheral surface, a first front surface, a first rear surface, and a first through cavity formed as a space surrounded by the first inner peripheral surface. The flipper has a second inner peripheral surface, a second outer peripheral surface, a second front surface, a second rear surface, and a second through cavity formed as a space surrounded by the second inner peripheral surface. The flipper is pivotally attached on the first front surface to move between a first and second position. In either the first or second position, the flipper is arranged to overlap on the first front surface and that the first through cavity is arranged to align with the second through cavity to allow a user's finger to pass through both main ring and flipper.

What is claimed is: 
     
         1 . A foldable ring, comprising:
 a main ring having a first inner peripheral surface, a first outer peripheral surface, a first front surface, a first rear surface, and a first through cavity formed as a space surrounded by said first inner peripheral surface; and   a flipper having a second inner peripheral surface, a second outer peripheral surface, a second front surface, a second rear surface, and a second through cavity formed as a space surrounded by said second inner peripheral surface, said flipper being pivotally attached on said first front surface to move between a first position and a second position, wherein in either said first position or said second position, said flipper is arranged to pivotally move to overlap on said first front surface of said main ring and that said first through cavity is arranged to align with said second through cavity so as to allow a user's finger to pass through both said main ring and said flipper.   
     
     
         2 . The foldable ring, as recited in  claim 1 , wherein a cross sectional shape of said flipper is substantially the same as that of an overlapping portion of said main ring. 
     
     
         3 . The foldable ring, as recited in  claim 2 , further comprising a hinge mechanism provided on said main ring for connecting with said flipper for moving said flipper between said first position and said second position. 
     
     
         4 . The foldable ring, as recited in  claim 3 , wherein said hinge mechanism is provided along an axis of symmetry of said main ring. 
     
     
         5 . The foldable ring, as recited in  claim 3 , wherein said hinge mechanism comprises a connector provided on said main ring, and a bolt inserted into a hole on said connector for connecting said main ring to said flipper. 
     
     
         6 . The foldable ring, as recited in  claim 1 , further comprising a stone setting as a part connecting said main ring for receiving and setting a main ornament stone. 
     
     
         7 . The foldable ring, as recited in  claim 1 , further comprising at least an ornament article provided on at least said first inner peripheral surface, said first outer peripheral surface, said first front surface, said first rear surface, said second inner peripheral surface, said second outer peripheral surface, said second front surface, and said second rear surface. 
     
     
         8 . The foldable ring, as recited in  claim 7 , wherein said ornament article comprises at least one of an engraved slot and a secondary ornamental stone. 
     
     
         9 . The foldable ring, as recited in  claim 1 , wherein said main ring has at least one of a substantially circular cross sectional shape, a substantially quadrilateral cross sectional shape, and a substantially elliptical cross sectional shape. 
     
     
         10 . A foldable ring, comprising:
 a main ring having a first inner peripheral surface, a first outer peripheral surface, a first front surface, a first rear surface, and a first through cavity formed as a space surrounded by said first inner peripheral surface; and   a flipper having a second inner peripheral surface, a second outer peripheral surface, a second front surface, a second rear surface, and a second through cavity formed as a space surrounded by said second inner peripheral surface, said flipper being pivotally attached on said first front surface to move between a first position and a second position; and   an auxiliary flipper having a third inner peripheral surface, a third outer peripheral surface, a third front surface, a third rear surface, and a third through cavity formed as a space surrounded by said third inner peripheral surface, said auxiliary flipper being pivotally attached on said first rear surface to move between a first position and a second position;   wherein in either said first position or said second position, said flipper and said auxiliary flipper are arranged to pivotally move to overlap on said first front surface and said first rear surface of said main ring respectively and that said first through cavity is arranged to align with said second through cavity and said third through cavity so as to allow a user's finger to pass through said main ring, said flipper and said auxiliary flipper.   
     
     
         11 . The foldable ring, as recited in  claim 10 , wherein a cross sectional shape of said flipper and said auxiliary flipper is substantially the same as that of an overlapping portion of said main ring. 
     
     
         12 . The foldable ring, as recited in  claim 11 , further comprising a hinge mechanism provided on said main ring for connecting with said flipper and said auxiliary flipper for moving said flipper and said auxiliary flipper between said first position and said second position. 
     
     
         13 . The foldable ring, as recited in  claim 12 , wherein said hinge mechanism is provided along an axis of symmetry of said main ring. 
     
     
         14 . The foldable ring, as recited in  claim 12 , wherein said hinge mechanism comprises a connector provided on said main ring, and a bolt inserted into a hole on said connector for connecting said main ring to said corresponding flipper and said auxiliary flipper. 
     
     
         15 . The foldable ring, as recited in  claim 10 , further comprising a stone setting as a part connecting said main ring for receiving and setting a main ornament stone. 
     
     
         16 . The foldable ring, as recited in  claim 10 , further comprising at least an ornament article provided on at least said first inner peripheral surface, said first outer peripheral surface, said first front surface, said first rear surface, said second inner peripheral surface, said second outer peripheral surface, said second front surface, said second rear surface, said third inner peripheral surface, said third outer peripheral surface, said third front surface, and said third rear surface. 
     
     
         17 . The foldable ring, as recited in  claim 16 , wherein said ornament article comprises at least one of an engraved slot and a secondary ornamental stone. 
     
     
         18 . The foldable ring, as recited in  claim 10 , wherein said main ring has at least one of a substantially circular cross sectional shape, a substantially quadrilateral cross sectional shape, and a substantially elliptical cross sectional shape.
