Abstract

An exemplary lockset is configured for installation in a standard door preparation, and includes an exterior assembly, an interior assembly, and a center assembly connecting the exterior and interior assemblies. The exterior assembly includes an exterior escutcheon which houses a credential reader assembly including a multi-tech credential reader. The interior assembly includes an interior escutcheon which houses a control system. The center assembly includes a chassis, an outer surface of which may define a channel. The credential reader assembly is in communication with the control assembly via a wire harness, a portion of which may pass through the channel.

First claim

What is claimed is:

1. A lockset assembly for mounting to a door, comprising:
an escutcheon having an inner region and an outer region;
a window on the escutcheon in the outer region;
a control assembly, including:
a first port configured for coupling the control assembly with a multi-tech credential reader, and a second port configured for coupling the control assembly with an electromechanical actuator;
a wireless transceiver generally aligned with the window and operable to receive data relating to an authorized credential;
a memory configured to store the authorized credential data; and
a controller configured to receive credential data via the first port, to compare the credential data to the authorized credential data, and to issue a signal via the second port in response to the compared credential data; and

a backplate coupled to the escutcheon and retaining the control assembly within the escutcheon, the backplate defining an opening extending between the inner region and the outer region of the escutcheon.

2. The lockset assembly of claim 1 , wherein the control assembly further comprises a jack including the first port and the second port; and
wherein the jack is positioned in the outer region of the escutcheon and is generally aligned with the opening.

3. The lockset assembly of claim 2 , further comprising a wire harness including:
a first plug engaged with the jack of the control assembly;
a second plug configured to engage a jack of the multi-tech credential reader;
a third plug configured to engage a jack of an electromechanical actuator;
a first plurality of wires connecting the first port with the second plug; and
a second plurality of wires connecting the second port with the third plug; and
wherein the first plurality of wires and second plurality of wires pass through the opening in the backplate.

4. The lockset assembly of claim 3 , further comprising:
a spindle extending through the escutcheon;
a chassis having an outer surface defining a channel in which the first plurality of wires are seated; and
a retractor configured to move in a lateral direction in response to rotation of the spindle; and
wherein the backplate further comprises a pair of lugs engaged with the chassis to couple the backplate with the chassis.

5. The lockset assembly of claim 1 , further comprising:
a spring cage positioned in the escutcheon and defining a boundary between the inner region and the outer region of the escutcheon.

6. The lockset assembly of claim 1 , further comprising:
a second escutcheon defining a second window;
a credential reader assembly, including a multi-tech credential reader positioned in the second escutcheon and generally aligned with the second window, the multi-tech credential reader operable to read credential data; and
a second backplate coupled to the second escutcheon and retaining the credential reader assembly within the second escutcheon.

7. A lockset assembly for mounting to a door, comprising:
an escutcheon having an inner region and an outer region;
a window in the outer region of the escutcheon;
a credential reader assembly, including:
a port configured for transmitting information from the credential reader assembly to a control assembly;
a multi-tech credential reader positioned in the escutcheon and generally aligned with the window, the multi-tech credential reader operable to read credential data via each of a first protocol and a second protocol, and to transmit the credential data via the port; and

a backplate coupled to the escutcheon and retaining the credential reader assembly within the escutcheon, the backplate defining an opening extending between the inner region and the outer region of the escutcheon.

8. The lockset assembly of claim 7 , further comprising:
a spring cage positioned in the escutcheon and defining a boundary between the inner region and the outer region of the escutcheon; and
a spindle rotatably mounted to the spring cage and extending through the escutcheon.

9. The lockset assembly of claim 7 , further comprising a pair of posts extending through the backplate, wherein the pair of posts are configured to engage fastener bores of a door preparation.

10. The lockset assembly of claim 7 , further comprising a center assembly including:
a chassis;
a drive spindle rotatably mounted to the chassis;
a retractor slidably mounted to the chassis and configured to move laterally in response to rotation of the drive spindle;
a locking member having an unlocking position in which the spindle is rotationally coupled with the drive spindle and a locking position in which the spindle is rotationally decoupled from the drive spindle; and
an electromechanical actuator operable to move the locking member between the unlocking position and the locking position.

11. The lockset assembly of claim 10 , further comprising a wire harness including a first plurality of wires in communication with the credential reader assembly via the port, and a second plurality of wires in communication with the electromechanical actuator; and
wherein the first plurality of wires extends through a channel defined by an outer surface of the chassis.

12. The lockset assembly of claim 11 , wherein the port is positioned in the outer region of the escutcheon, wherein the first plurality of wires extends between the inner region and the outer region via the opening, and wherein the port further comprises a wireless transceiver operable to wirelessly transmit the information to the control assembly.

13. A lockset assembly for mounting to a door, comprising:
an exterior assembly for mounting to an exterior of the door, including:
an exterior escutcheon;
a credential reader assembly including a multi-tech credential reader positioned in the exterior escutcheon and operable to read a credential via each of a first protocol and a second protocol, and to transmit data relating to the credential in response to reading of the credential; and
an exterior backplate coupled to the exterior escutcheon and retaining the multi-tech credential reader within the exterior escutcheon;

an interior assembly for mounting to an interior of the door, including:
an interior escutcheon;
a control assembly positioned in the interior escutcheon and in communication with the credential reader assembly via a first plurality of wires, the control assembly including a controller configured to receive credential data, to compare the credential data to an authorized credential, and to issue a signal in response to the compared credential data;
an interior backplate coupled to the interior escutcheon and retaining the control assembly within the interior escutcheon.

14. The lockset assembly of claim 13 , further comprising a center assembly for mounting on the door, including:
a locking member having an unlocking position and a locking position; and
an electromechanical actuator in communication with the control assembly via a second plurality of wires, wherein the controller is configured to issue the signal through at least one of the second plurality of wires, and wherein the electromechanical actuator is configured to move the locking member between the locking position and unlocking position in response to the signal.

15. The lockset assembly of claim 14 , further comprising:
a wire harness comprising a first strip including the first plurality of wires, a second strip including the second plurality of wires, an exterior plug engaged with the credential reader assembly, an interior plug engaged with the control assembly, and an actuator plug engaged
