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 free…
