Abstract
A plug assembly includes a retractable pivoting mechanism, offering temporarily one or more seating surfaces for an untethered object. The retractable pivoting mechanism has two or three pivoting positions, allowing the passage or the seating of an untethered object depending on the flow direction. The retractable pivoting mechanism can include a single retractable pivoting ring or multiple segments forming a ring after pivoting in their closed position. Another embodiment of the retractable pivoting mechanism includes a latching feature allowing to keep the mechanism in an opened position.
