Abstract

A deadbolt lock includes a deadbolt, a user rotatable actuator, and a lock interface. The user rotatable actuator is operatively connected with the deadbolt for movement of the deadbolt between locked and unlocked conditions when the actuator is changed from an inoperable condition to an operable condition. The lock interface is configured to change the actuator from the inoperable condition to the operable condition in response to proper user manipulation of the lock interface.

Claims

1. A deadbolt lock for assembly with a door, the deadbolt lock comprising:

a deadbolt movable between locked and unlocked positions;

a user rotatable actuator changeable between inoperable and operable conditions and accessible from an exterior side of a door when the deadbolt lock is assembled with the door, the actuator being operatively connected with the deadbolt for movement of the deadbolt between locked and unlocked conditions when the actuator is in an operable condition; and

a lock interface accessible from the exterior side of the door when the deadbolt lock is assembled with the door, the lock interface being configured to change the actuator from the inoperable condition to the operable condition in response to proper user manipulation of the lock interface.

2. The deadbolt lock of claim 1, further comprising an actuation translating component, wherein when the actuator is changed from the inoperable condition to the operable condition, the actuation translating component becomes operatively connected with the actuator.

3. The deadbolt lock of claim 2, wherein the actuator comprises a cover member configured to cover at least a portion of a lock cylinder.

4. The deadbolt lock of claim 2, wherein the actuation translating component comprises a clutch ring, wherein the clutch ring securely engages an end portion of the actuator for mutual rotation of the actuator and clutch ring when the actuator is in the operable condition.

5. The deadbolt lock of claim 4, wherein the actuator comprises at least one notch and the clutch ring comprises at least one projection, wherein the at least one projection securely engages the at least one notch when the actuator is in the operable condition.

6. The deadbolt lock of claim 4, further comprising an electronic latch connected with the lock interface, wherein proper user manipulation of the lock interface energizes the electronic latch to hold the clutch ring in secure engagement with the actuator.

7. The deadbolt lock of claim 4, further comprising a drive arm assembled with the clutch ring, the drive arm providing an operative connection between the clutch ring and the deadbolt.

8. The deadbolt lock of claim 7, wherein the clutch ring is axially slideable with respect to each of the actuator and the drive arm.

9. The deadbolt lock of claim 1, wherein the lock interface is configured to receive a data signal for comparison with one or more stored authorized data signals.

10. The deadbolt lock of claim 9, wherein the one or more stored authorized data signals are associated with an inherent trait of an authorized user.

11. The deadbolt lock of claim 10, wherein the inherent trait comprises a fingerprint pattern.

12. The deadbolt lock of claim 1, further comprising a lockout mechanism accessible from an interior side of a door when the deadbolt lock is assembled with the door, the lockout mechanism being configured such that when the actuator is in an operable condition and the lockout mechanism is moved to a lockout position, the lockout mechanism prevents rotation of the actuator to move the deadbolt between locked and unlocked positions.

13. The deadbolt lock of claim 12, wherein the lockout mechanism comprises a shaft operatively connected with the actuator when the actuator is in an operable condition, the shaft including a head portion having at least one depression, and a shaft housing including an opening for receiving said shaft and a collar surrounding at least a portion of said opening, wherein said head portion of said shaft is selectively movable into and out of nesting engagement with the collar such that when the head portion is nested within the collar, the at least one depression engages one or more portions of the collar, thereby preventing rotation of the shaft.

14. The deadbolt lock of claim 12, wherein the lockout mechanism further comprises an indication mechanism for providing a visual indication when the lockout mechanism is in the lockout position.

15. The deadbolt lock of claim 12, wherein the lockout mechanism further comprises a lockout release mechanism, wherein movement of the lockout release mechanism from an engaging position to a release position permits movement of the lockout mechanism to the lockout position.

16. The deadbolt lock of claim 15, wherein when the lockout mechanism is in the lockout position and the lockout release mechanism is in the engaging position, the lockout mechanism is freely moveable out of the lockout position.

17. A deadbolt lock comprising:

a deadbolt movable between locked and unlocked positions;

a manually operable locking member operatively connected with the deadbolt for movement of the deadbolt between locked and unlocked conditions when the locking member is changed from an inoperable condition to an operable condition; and

a lock interface accessible from the exterior side of the door when the deadbolt lock is assembled with the door, the lock interface being configured to change the manually operable locking member from the inoperable condition to the operable condition when the lock interface receives an authorized data signal.

18. The deadbolt lock of claim 17, wherein the lock interface comprises a fingerprint scanner and the authorized data signal is associated with a fingerprint of an authorized user.

19. The deadbolt lock of claim 17, wherein the lock interface is configured to energize an electronic latch to operatively connect the locking member with the deadbolt when the lock interface receives an authorized data signal.

20. The deadbolt lock of claim 19, wherein when the electronic latch is energized, the electronic latch holds an actuation translating component in secure engagement with the locking member for operatively connecting the locking member with the deadbolt.

21. A method for unlocking a deadbolt lock from an exterior side of a door, the method comprising:

transmitting an authorized data signal to a lock interface;

operatively connecting a manually operable locking member with a deadbolt in response to receipt of the authorized data signal by the lock interface; and

moving the manually operable locking member, such that the deadbolt is moved from a locked position to an unlocked position.

22. The method of claim 21, wherein transmitting the authorized data signal to the lock interface comprises scanning a fingerprint of an authorized user.

23. The method of claim 21, wherein operatively connecting the manually operable locking member with the deadbolt comprises operatively connecting an actuation translating member with the manually operable locking member, the actuation translating member being operatively connected with the deadbolt.

24. The method of claim 23, wherein operatively connecting the actuation translating member with the manually operable locking member comprises energizing an electronic latch to hold the actuation translating member in secure engagement with the manually operable locking member.

25. The method of claim 21, further comprising operatively disconnecting the manually operable locking member from the deadbolt after a predetermined period of time from receipt of the authorized data signal.
