Abstract
A lock assembly including a plurality of dogs, each dog having a load bearing surface and a first interconnection feature. An extender body is operatively arranged for radially transitioning the plurality of dogs between a retracted configuration and an extended configuration. The load bearing surface of each dog is operatively arranged in the extended configuration for engaging against a shoulder of a radially adjacent structure for supporting the lock assembly. A mandrel is included having a second interconnection feature operatively arranged to dimensionally overlap the first interconnection feature of the dogs when transitioned to the extended configuration for enabling the mandrel to be supported by the dogs. A method of locking radially adjacent components is also included.
