Abstract

An exemplary apparatus includes a housing, a lock mechanism mounted to the housing, an electromechanical driver, a first override mechanism, and a second override mechanism. The electromechanical driver is mounted to the housing and is operable to unlock the lock mechanism. The first override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The second override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The apparatus has a first configuration in which a lock cylinder is engaged with the first override mechanism such that actuation of the lock cylinder unlocks the lock mechanism. The apparatus has a second configuration in which the lock cylinder is engaged with the second override mechanism such that actuation of the lock cylinder unlocks the lock mechanism.

First claim

What is claimed is:

1. A lock module configured for use with each of a first lock cylinder and a second lock cylinder configured the same as or different from the first lock cylinder, the lock module comprising:
a housing;
a lock mechanism movably mounted to the housing;
a first override mechanism movably mounted to the housing and configured for engagement with the first lock cylinder; and
a second override mechanism movably mounted to the housing and configured for engagement with the second lock cylinder;
wherein, with the first lock cylinder engaged with the first override mechanism, the first lock cylinder is operable to unlock the lock mechanism via the first override mechanism; and
wherein, with the second lock cylinder engaged with the second override mechanism, the second lock cylinder is operable to unlock the lock mechanism via the second override mechanism.

2. The lock module of claim 1 , further comprising:
an electrically-operable driver mounted to the housing and operable to unlock the lock mechanism; and
a control assembly operable to control the electrically-operable driver to unlock the lock mechanism.

3. The lock module of claim 2 , wherein the electrically-operable driver is operable to unlock the lock mechanism independently of the first override mechanism and independently of the second override mechanism.

4. The lock module of claim 1 , wherein the lock mechanism is configured to unlock in response to a sliding movement of the first override mechanism along a sliding axis; and
wherein the lock mechanism is configured to unlock in response to a rotational movement of the second override mechanism about a rotational axis.

5. The lock module of claim 4 , wherein the sliding axis extends in a direction defined by the rotational axis.

6. The lock module of claim 1 , wherein, with the first lock cylinder engaged with the first override mechanism, a plug of the first lock cylinder is rotatable about a first rotational axis to thereby actuate the first override mechanism;
wherein, with the second lock cylinder engaged with the second override mechanism, a plug of the second lock cylinder is rotatable about a second rotational axis to thereby actuate the first override mechanism; and
wherein the first rotational axis and the second rotational axis are transverse to one another.

7. The lock module of claim 1 , further comprising:
a first hub rotatably mounted in the housing;
a second hub rotatably mounted in the housing; and
a coupler operable to selectively rotationally couple the first hub and the second hub;
wherein the first hub is operable to rotate relative to the second hub when the lock mechanism is locked; and
wherein the first hub and the second hub are rotationally coupled via the coupler when the lock mechanism is unlocked.

8. The lock module of claim 1 , wherein the lock module has a first configuration in which the first lock cylinder is engaged with the first override mechanism;
wherein the lock module has a second configuration in which the second lock cylinder is engaged with the second override mechanism; and
wherein the lock module is operable to transition between the first configuration and the second configuration without opening the housing.

9. The lock module of claim 1 , wherein the housing has a box-shaped geometry.

10. A system, comprising:
a lock module comprising a first override mechanism and a second override mechanism;
a first lock apparatus comprising a first lock cylinder, wherein, with the lock module installed to the first lock apparatus, the first lock cylinder is operable to unlock the lock module via the first override mechanism; and
a second lock apparatus comprising a second lock cylinder, wherein, with the lock module installed to the second lock apparatus, the second lock cylinder is operable to unlock the lock module via the second override mechanism.

11. The system of claim 10 , wherein each of the first override mechanism and the second override mechanism is independently operable to unlock the lock module.

12. The system of claim 10 , wherein the first lock apparatus comprises a first escutcheon in which the lock module is seated when the lock module is installed to the first lock apparatus; and
wherein the second lock apparatus comprises a second escutcheon in which the lock module is seated when the lock module is installed to the second lock apparatus.

13. The system of claim 10 , wherein the lock module further comprises an electrically-operable driver operable to unlock the lock module.

14. The system of claim 13 , wherein the first lock apparatus comprises a first control assembly operable to control the electrically-operable driver when the lock module is installed to the first lock apparatus; and
wherein the second lock apparatus comprises a second control assembly operable to control the electrically-operable driver when the lock module is installed to the second lock apparatus.

15. The system of claim 10 , wherein a first rotational axis of a first plug of the first lock cylinder extends longitudinally; and
wherein a second rotational axis of a second plug of the second lock cylinder extends transverse to the second longitudinal axis.

16. A method of assembling an access control device in a selected configuration, the method comprising:
selecting a lock apparatus based upon the selected configuration, wherein the lock apparatus is selected from:
a first lock apparatus comprising a first lock cylinder; and
a second lock apparatus comprising a second lock cylinder; and

installing a lock module to the selected lock apparatus, the lock module comprising a first override mechanism and a second override mechanism;
wherein, when the selected lock apparatus is the first lock apparatus, the installing comprises engaging the first lock cylinder with the first override mechanism such that the first lock cylinder is operable to unlock the lock module; and
wherein, when the selected lock apparatus is the second lock apparatus, the installing comprises engaging the second lock cylinder with the second override mechanism such that the second lock cylinder is operable to unlock the lock module.

17. The method of claim 16 , wherein the lock module further comprises an electrically-operable driver operable to unlock the lock module; and
wherein the installing further comprises placing the electrically-operable driver in communication with a control assembly of the selected lock apparatus.

18. The method of claim 16 , wherein an orientation of the first lock cylinder relative to the first lock apparatus is different from an orientation of the second lock cylinder relative to the second lock apparatus.

19. The method of claim 16 , wherein the first lock cylinder has a horizontal orientation in the first lock apparatus; and
wherein the second lock cylinder has a vertical orientation in the second lock apparatus.

20. The method of claim 16 , wherein the lock module further comprises a first hub and a second hub;
wherein the first hub is operable to rotate relative to the second hub when the lock module is locked;
wherein the first hub is rotationally coupled with the second hub when the lock module is unlocked; and
wherein the installing comprises engaging the first hub with a spindle of the selected lock apparatus, and engaging the second hub with a latch mechanism of the selected lock apparatus.
