Electronic deadbolt lock
A deadbolt lock assembly including a retractable and extendable deadbolt, a housing, an outside member movably mounted on the housing and being normally disconnected from the deadbolt, and an operator input device on the housing, with the operator input device connecting the member to the deadbolt in response to presentation of an appropriate credential, such that a force applied to the member by the operator is mechanically transmitted to the deadbolt to move the deadbolt.
1. A lock assembly, comprising:
a bolt mounted for movement between an extended position and a retracted position;
a housing configured for mounting to a door;
a manual actuator rotatably mounted to the housing, wherein the manual actuator is normally disconnected from the bolt such that the manual actuator is not operable to move the bolt between the extended position and the retracted position; and
a lock cylinder operable to translate relative to the housing between a first axial position and a second axial position, wherein when an appropriate key is inserted into the lock cylinder and rotated from a home position to a rotated position, movement of the lock cylinder from the first axial position to the second axial position connects the manual actuator to the bolt to thereby permit the manual actuator to move the bolt between the extended position and the retracted position.
2. The lock assembly of claim 1 , wherein when the appropriate key is not inserted, movement of the lock cylinder from the first position toward the second position does not connect the manual actuator to the bolt.
3. The lock assembly of claim 1 , further comprising a credential reader and a motor, wherein when an appropriate credential is presented to the credential reader, the motor connects the manual actuator to the bolt.
4. The lock assembly of claim 3 , wherein the lock cylinder and the motor are independently operable to connect the manual actuator to the bolt.
5. The lock assembly of claim 3 , further comprising a clutch;
wherein the clutch has a clutching position in which the manual actuator is operably connected with the bolt via the clutch;
wherein the clutch has a declutching position in which the manual actuator is not operably connected with the bolt via the clutch; and
wherein the motor is operable to drive the clutch between the clutching position and the declutching position.
6. The lock assembly of claim 1 , wherein the credential reader comprises a keypad.
7. The lock assembly of claim 1 , wherein the lock cylinder is mounted in the manual actuator.
8. A lock assembly, comprising:
an extendable and retractable bolt;
a housing;
a manual actuator rotatably mounted to the housing;
an adapter connected with the manual actuator, the adapter including a plurality of notches;
a rotatable member engaged with the bolt such that rotation of the rotatable member moves the bolt; and
a coupler mounted to the rotatable member, the coupler having a coupling position in which the coupler is received in one of the notches and rotationally couples the adapter with the rotatable member to thereby permit the manual actuator to move the bolt, and the coupler having a decoupling position in which the coupler is not received in any of the notches such that the adapter is decoupled from the rotatable member.
9. The lock assembly of claim 8 , further comprising a credential reader mounted to the housing, and an electronic actuator configured to move the coupler from the decoupling position to the coupling position when an appropriate credential is presented to the credential reader.
10. The lock assembly of claim 9 , wherein the credential reader comprises a keypad.
11. The lock assembly of claim 9 , wherein the electronic actuator comprises a motor having a rotatable output shaft, a movable wall engaged with the coupler, and a spring engaged between the output shaft and the movable wall such that the spring urges the wall between a first position and a second position in response to rotation of the output shaft.
12. The lock assembly of claim 9 , further comprising a lock cylinder operable to connect the manual actuator to the rotatable member, wherein the lock cylinder and the electronic actuator are independently operable to connect the manual actuator to the rotatable member.
13. The lock assembly of claim 8 , further comprising a lock cylinder operable to connect the manual actuator to the rotatable member while the coupler remains in the decoupling position.
14. The lock assembly of claim 8 , wherein the manual actuator is operable to rotate relative to the housing through a rotational range of at least 360°.
15. The lock assembly of claim 8 , wherein a first notch of the plurality of notches is aligned with the coupler when the manual actuator is in a first rotational orientation; and
wherein a second notch of the plurality of notches is aligned with the coupler when the manual actuator is in a second rotational orientation different from the first rotational orientation.
16. A lock assembly, comprising:
a bolt mounted for movement between an extended position and a retracted position;
a housing configured for mounting to a door;
a manual actuator rotatably mounted to the housing, wherein the manual actuator is normally disconnected from the bolt;
a credential reader mounted to the housing;
an electronic actuator configured to operably connect the manual actuator to the bolt in response to presentation of an appropriate credential to the credential reader; and
a lock cylinder configured to operably connect the manual actuator to the bolt in response to actuation of the lock cylinder by an appropriate key;
wherein the electronic actuator and the lock cylinder are independently operable to connect the manual actuator to the bolt such that only one of the appropriate key or the appropriate credential is required to connect the manual actuator to the bolt; and
wherein the manual actuator is operable to be operably connected to the bolt when the manual actuator is in each of a plurality of rotational orientations relative to the housing.
17. The lock assembly of claim 16 , wherein the credential reader comprises a keypad.
18. The lock assembly of claim 16 , wherein the lock cylinder is axially movable between a first position and a second position;
wherein the lock cylinder comprises a tailpiece that, upon insertion of the appropriate key, is rotatable from a home position to a rotated position; and
wherein with the tailpiece in the rotated position, movement of the lock cylinder from the first position to the second position engages the manual actuator with the bolt.
19. The lock assembly of claim 18 , wherein the tailpiece is collapsible such that when the tailpiece is in the home position, movement of the lock cylinder from the first position to the second position collapses the tailpiece and does not engage the manual actuator with the bolt.
20. The lock assembly of claim 16 , wherein the lock cylinder is mounted in the manual actuator.
21. The lock assembly of claim 16 , further comprising:
a rotatable member engaged with the bolt such that rotation of the rotatable member moves the bolt;
an adapter mounted to the manual actuator, the adapter including a notch; and
a coupler movably mounted to the rotatable member and operable to enter the notch to rotationally couple the rotatable member with the adapter; and
wherein the electronic actuator is operable to move the coupler between a coupling position and a decoupling position to selectively connect the manual actuator with the deadbolt.
22. The lock assembly of claim 21 , wherein the adapter includes a plurality of the notches such that the electronic actuator is operable to connect the manual actuator to the bolt when the manual actuator is in each of a plurality of positions.
23. The lock assembly of claim 16 , wherein the manual actuator is operable to rotate relative to the housing through a rotational range of at least 360°.
