ABSTRACT:
A finger ring size opening adjustment device comprises a cradle which is extended from a first open position within the shank of a ring to second closed position reducing the ring size and permitting the wearer of the ring a sufficient size to easily slide over an enlarged knuckle or joint and to then be reduced to a desired fit on the phalanx portion of the finger. An extensible arm member provides the positioning of the cradle and is modified to provide various size ring openings. In one embodiment of the invention, a lever arm is rotatably connected to the cradle wherein the lever arm remains within the body of the shank while holding the cradle in its closed position. In alternate embodiments described, extensible members include telescoping set screws, a set screw and guide post, and a piston extended by pressurizing chamber about the piston. In each embodiment, the extensible mechanism remains within the boundaries of the shank permitting the ring having the adjustment device to be used in juxtaposition with a second or companion ring.
