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.

The invention claimed is: 1. A dead bolt locking system for use on a door leading to a secure area, the dead bolt locking system comprising: a housing structure adapted to be mounted on an inside of the door; a dead bolt mounted in the housing structure for movement between extended and retracted positions; a lock operatively connected with the dead bolt and controlled by the input of correct unlocking information to allow movement of the dead bolt from the extended position to the retracted position; dead bolt retracting structure operatively connected to the dead bolt such that when the lock is unlocked, at least a portion of the dead bolt retracting structure is operative to allow retraction of the dead bolt and, when the lock is locked, operation of the dead bolt retracting structure is prevented thereby preventing retraction of the dead bolt; and an inertia assembly mounted to the housing structure, the inertia assembly having an actuator weight configured to rotate and translate relative to a pivot axis during the application of a shock load and a bolt lock lever configured to rotate about the pivot axis when the actuator weight translates relative to the pivot axis, the bolt lock lever including a portion that has a contacting relationship with a portion of the dead bolt, when the actuator weight and the bolt lock lever rotate about the pivot axis, to prevent movement of the dead bolt from the extended position to the retracted position and that has a non-contacting relationship with the portion of the dead bolt in the absence of the shock load. 2. The dead bolt locking system of claim 1 wherein the actuator weight has an arm and a slot in the arm configured to enable rotation and translation of the actuator weight during the application of the shock load; and a bolt lock lever operatively coupled to the actuator weight, the bolt lock lever including a hook for contacting the portion of the dead bolt when the actuator weight and the bolt lock lever rotate about the pivot axis and an opening aligned with the slot. 3. The dead bolt locking system of claim 2 wherein the inertia assembly further comprises: a return spring configured for biasing the actuator weight about the pivot axis; and a stud extending through the return spring, the opening of the bolt lock lever, and the slot of the actuator weight for coupling to the housing structure, the stud providing the pivot axis; wherein application of the shock load causes the actuator weight to translate by sliding the slot relative to the stud. 4. The dead bolt locking system of claim 3 wherein the arm of the actuator weight further includes a cam surface, and the inertia assembly further comprises: a curved post coupled to the housing structure, said curved post including a cam surface cooperating with the cam surface on the arm of the actuator weight to rotate the actuator weight and the bolt lock lever when the actuator weight translates. 5. The dead bolt locking system of claim 1 wherein the inertia assembly further comprises: a return spring configured for applying a torque to the actuator weight to return the actuator weight to a neutral position after the application of a shock load. 6. A dead bolt locking system for use on a door leading to a secure area, the dead bolt locking system comprising: an enclosed housing structure having an interior and adapted to be mounted to the door; a dead bolt mounted in the interior of the housing structure for movement between an extended position in which a portion of the dead bolt extends out of the interior of the housing structure and a retracted position in which the dead bolt is more fully contained within the interior of the housing structure; a security lock including a casing and a lock member each contained within the interior of the housing structure and the lock member moved from a locked condition extending outwardly from the casing to an unlocked condition retracted within the casing by the input of correct unlocking information; dead bolt retracting structure operatively connected to the dead bolt for moving the dead bolt from the extended position to the retracted position, the dead bolt retracting structure having a slotted opening with a first portion extending transversely relative to the direction of movement of the lock member and a second portion extending substantially parallel to the direction of movement of the lock member; a test member mounted within the housing structure and having a portion movable within the first and second portions of the slotted opening as the dead bolt retracting structure moves the dead bolt from the extended position to the retracted position, the test member further mounted for movement relative to the dead bolt and coupled with the dead bolt retracting structure to prevent retraction of the dead bolt when the lock member is in the locked condition and movable into a space created by the lock member in the unlocked condition to thereby allow retraction of the dead bolt; and an inertia assembly mounted to the housing structure, the inertia assembly having a portion configured for contacting a portion of the dead bolt to prevent movement of the dead bolt to the retracted position during the application of a shock load. 7. The dead bolt locking system of claim 6 wherein a portion of the inertia assembly translates and rotates to prevent movement of the dead bolt to the retracted position during the application of a shock load. 8. The dead bolt locking system of claim 6 wherein the inertia assembly further includes cam surfaces configured for moving a portion of the inertia assembly into a position during the application of a shock load to prevent movement of the dead bolt. 9. The dead bolt locking system of claim 6 wherein a portion of the inertia assembly is configured to prevent movement of the dead bolt from the application of a shock load from a first direction or a second direction generally opposite to the first direction. 10. The dead bolt locking system of claim 6 wherein the inertia assembly further comprises: an actuator weight having an arm configured for rotational movement and a slot in the arm configured to enable translation of the arm of the actuator weight during the application of the shock load; and a bolt lock lever operatively coupled to the actuator weight, the bolt lock lever including a hook configured for restraining the dead bolt and an opening aligned with the slot. 11. The dead bolt locking system of claim 10 wherein the inertia assembly further comprises: a return spring configured for biasing the actuator weight in a rotational direction; and a stud passing through the return spring, the opening of the bolt lock lever, and the slot of the actuator weight, the stud configured for coupling to the housing structure and providing a pivot for enabling the rotation of the actuator weight and the bolt lock lever; wherein application of the shock load causes the actuator weight to translate by sliding the slot relative to the stud. 12. The dead bolt locking system of claim 11 wherein the inertia assembly further comprises: a curved post coupled to the housing structure cooperating with the arm of the actuator weight to rotate the actuator weight and the bolt lock lever when the actuator weight translates. 13. The dead bolt locking system of claim 12 wherein the rotation of the bolt lock lever prevents retraction of the dead bolt during application of the shock load. 14. The dead bolt locking system of claim 6 wherein a portion of the inertia assembly moves rotationally to prevent movement of the dead bolt during application of the shock load. 15. The dead bolt locking system of claim 6, wherein the inertia assembly further comprises: a return spring for applying a torque to the actuator weight to return the actuator weight to a neutral position after the application of a shock load.
