ABSTRACT:
Load ring assemblies are disclosed which can be releasably connected to a load and provide a load ring mounted for pivotal movement so that the load ring can align itself with a connecting force applied thereto. The assembly includes a mounting member formed with a central flange intermediate its ends and cylindrical extensions extending in both directions therefrom. A pivot collar or ring is journaled on one extension for pivotal movement about the longitudinal axis of the mounting member. A U-bar or load ring is pivoted on the collar for pivotal movement about a second axis perpendicularly intersecting the first axis. Therefore, the load ring is free to pivot relative to the mounting member into alignment with a force applied thereto. The other extension is provided with a locking system having a plurality of peripherally located locking elements which are radially movable between an extended locking position and a retracted release position. In the extended position, the locking elements operate to engage a mating receptacle and lock the mounting member and the entire assembly in a load in which the receptacle is mounted. In the retracted position, the load ring assembly is freely removable from or insertable into the receptacle. The radial position of the locking elements is controlled by a threaded bolt accessible from the free end of the assembly which is operable to positively lock the locking elements in the extended and locked position and which can be retracted to allow movement of the locking elements to the retracted position.
