LOCK ASSEMBLY WITH CAGELESS DOGS |
摘要 |
A lock assembly including a plurality of dogs, each dog being circumferentially adjacent to at least one other dog in the plurality and each dog including a load bearing surface. An extender body is operatively arranged to transition 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. The load bearing surfaces of the dogs together form a substantially circumferentially continuous shape when arranged in one of the retracted or extended configurations. A method of locking radially adjacent components is also included. |
