Abstract
A quick-disconnect locking system for interconnecting sections of a rigid yoke structure comprises a female truncated cone adapted to be connected at its narrow end to one section of a two-piece yoke assembly, and a male truncated cone which is nestable within the female cone and is adapted to be connected at its larger end to the other section of the yoke. When locked, the male and female cones are closely nested and are locked together by a plurality of shear keys which project radially out of the larger end of the male cone into a continuous channel on the inner face of a locking ring attached to the larger end of the female cone. To unlock the assembly, the shear keys are withdrawn radially into the male cone, thus permitting the cone structures to be disengaged. For facilitating nesting of the cones, the smaller end of the male cone is provided with retractable means which engages the female cone and draws the two cones into a closely nested position. Separation of the cones is also aided by the same mechanism which is operated in a reverse direction to push the cones apart.
