Abstract:
1. An elevator for use with a tubular string comprising: a main body that is selectively moveable between an open configuration and a closed configuration; an axial opening in the main body that selectively circumscribes the tubing when the main body is in the closed configuration; a lug that projects outward from the main body; a retainer having an end pivotingly coupled on a lateral surface of the main body that is moveable into a latching configuration with the lug so that the main body is held in the closed configuration; a retainer stop in the main body moveable into selective locking engagement with the retainer so that the retainer remains in the latching configuration with the lug when in locking engagement with the retainer stop; a boss that projects radially inward from an inner surface of the retainer towards the tubular string, so that when the retainer stop is in locking engagement with the retainer, the retainer stop is in a path followed by the boss when the retainer is pivoted away from the main body; and wherein the retainer stop comprises a planar upper section and a cylindrical shaped lower section, wherein the lower section inserts into an axial bore in the main body, and wherein when the upper section contacts a collar on the tubular string, the retainer stop is urged axially into the main body so that the lower section is moved into locking engagement with the retainer.
