ABSTRACT:
A dead bolt lock system having one or more security locks in conjunction with a dead bolt to provide various levels of security access to a door. An inertia assembly restrains movement of the dead bolt when a shock load is applied to the door, but allows the dead bolt to move when a shock load is not present. The inertia assembly includes an actuator weight and a bolt lock lever that can translate and rotate in response to the application of the shock load. In addition, the inertia assembly includes a return spring that biases the inertia assembly back into its original position for facilitating movement of the dead bolt after the application of the shock load.
