Patent ID: 7179011

Claim:
An actuator piston and rod-end locking device for locking a first fitting to a second fitting, the first fitting including a longitudinal groove and an exterior threaded portion, the device comprising: a locking support body slidably mounted on the first fitting, said locking support body positioned in engagement with the second fitting to prevent rotation of the second fitting; a shelf element mounted on said locking support body, said shelf element extending over the second fitting; a fastening member mounted on said shelf element and interposed radially between said shelf element and the second fitting, said fastening member capable of pivotal movement relative to said shelf element, wherein said fastening member pivots relative to said shelf element into engagement with the second fitting to secure said locking support body to the second fitting; a locking ring element including locking threads, said locking ring element being threadably and rotationally locked onto said first fitting, wherein a locking engagement between said locking threads of said locking ring element and the exterior threaded portion of the first fitting results in said threadably and rotationally locked configuration of said locking ring element and the first fitting, wherein said locking support body is positioned between said locking ring element and the second fitting such that said locking ring element prevents axial separation between said locking support body and the second fitting upon an application of axial force tending to separate said first fitting from said second fitting; and a means for biasing said fastening member away from said shelf element.
