Improvements in the articulated connections, in particular to universal joints for articulated connection of a off - shore safari on the sea bottom.

摘要

A universal Cardan joint coupling device for pivotally connecting an off-shore oil-field working articulated column to a base member resting or anchored on the sea bed, wherein the improvement consists in that at least one of the pivot axes of said joint is connected to two supports rigidly connected to said base member and provided on either side of said joint, by means of two lock-bolt means aligned and displaceable along said axis and adapted to cooperate with bolt-clasps or keepers provided in said supports.
