Patent ID: 7150164

Claim:
A finger ring fit adjustment method employing a tubular bladder with a radially outer wall that is anchored to a ring band inside surface and a flexible radially inside wall integral with the radially outer wall and cooperating with the radially outer wall to form a gas chamber that extends 360° around an axis of a ring finger passage through the tubular bladder comprising: opening a gas valve in communication with the gas chamber to permit adjustment of the quantity of a gas in the gas chamber and thereby adjust ring fit; adjusting the quantity of air in the gas chamber; closing the gas valve to maintain a selected quantity of gas in the gas chamber; inserting a finger into the ring finger passage through the tubular bladder; compressing a gas in the gas chamber by enlarging an inside diameter of the ring finger passage as the finger moves into the ring finger passage; forming the shape and size of the radially inside wall to conform to the size and shape of a finger knuckle as the finger knuckle passes through the tubular bladder; and expanding the gas chamber and reducing the pressure of the gas in the gas chamber by moving the finger knuckle through the tubular bladder and allowing the inside diameter of the ring finger passage to decrease and conform to a finger size between a pair of finger joints.
