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, comprising:
an exterior assembly configured for mounting on an exterior surface of a door having a standard door preparation comprising a standard cross-bore and a pair of standard fastener bores positioned on opposite sides of the standard cross-bore, the exterior assembly comprising:
an exterior escutcheon;
an exterior window mounted on the exterior escutcheon;
a credential reader assembly including a multi-tech credential reader positioned in the exterior escutcheon and aligned with the exterior window, the multi-tech credential reader 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 the reading;
an exterior spring cage housed in the exterior escutcheon;
an exterior spindle rotatably mounted to the exterior spring cage and extending through the exterior escutcheon in a longitudinal direction; and
an exterior backplate coupled to the exterior escutcheon and retaining the exterior spring cage and the multi-tech credential reader within the exterior escutcheon;

an interior assembly configured for mounting on an interior surface of the door, the interior assembly comprising:
an interior escutcheon;
a control assembly housed in the interior escutcheon in communication with the credential reader assembly via a first plurality of wires, the control assembly including a controller configured to receive the credential data, to compare the credential data to an authorized credential, and to issue a signal in response to the comparing;
an interior spring cage housed in the interior escutcheon;
an interior spindle rotatably mounted to the interior spring cage and extending through the interior escutcheon in the longitudinal direction; and
an interior backplate coupled to the interior escutcheon and retaining the interior spring cage and the control assembly within the interior escutcheon;

a center assembly configured for mounting in the standard door preparation, the center assembly comprising:
a chassis configured for mounting in the standard cross-bore, an outer surface of the chassis defining a channel extending in the longitudinal direction, and wherein the first plurality of wires extends along the channel;
a locking member having an unlocking position and a locking position;
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; and
a retractor slidably mounted to the chassis and configured to move laterally in response to rotation of the interior spindle;
wherein, with the locking member in the unlocking position, rotation of the exterior spindle is operable to move the retractor laterally; and
wherein, with the locking member in the locking position, the exterior spindle is not operable to move the retractor laterally;

a pair of posts extending in the longitudinal direction from one of the exterior spring cage and the interior spring cage, wherein the pair of posts are configured to be received in the standard fastener bores; and
a pair of fasteners extending in the longitudinal direction from the other of the exterior spring cage and the interior spring cage, wherein each fastener is engaged with a corresponding one of the posts.

2. The lockset of claim 1 , wherein the center assembly further comprises:
an inner drive spindle rotatably mounted to the chassis and rotationally coupled with the interior spindle, wherein the retractor is configured to move laterally in response to rotation of the inner drive spindle; and
an outer drive spindle rotatably mounted to the chassis, wherein the retractor is further configured to move laterally in response to rotation of the outer drive spindle; and
wherein, with the locking member in the unlocking position, the outer drive spindle is rotationally coupled with the exterior spindle; and
wherein, with the locking member in the locking position, the outer drive spindle is rotationally decoupled from the exterior spindle.

3. The lockset of claim 2 , wherein the center assembly further comprises a sleeve spindle rotationally coupled with the exterior spindle; and
wherein, with the locking member in the unlocking position, the outer drive spindle is rotationally coupled with the sleeve spindle; and
wherein, with the locking member in the locking position, the outer drive spindle is rotationally decoupled from the sleeve spindle.

4. The lockset of claim 1 , 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 with the electromechanical actuator; and
wherein the first strip connects the exterior plug and the interior plug; and
wherein the second strip connects the interior plug and the actuator plug.

5. The lockset of claim 4 , wherein the chassis further comprises a pair of flanges partially enclosing the channel; and
wherein a distance between the flanges is less than a width of the first strip.

6. The lockset of claim 1 , wherein the exterior spring cage comprises a lip abutting the exterior backplate;
wherein the exterior backplate comprises an opening aligned with the lip; and
wherein the first plurality of wires extends through the opening.

7. The lockset of claim 6 , wherein the interior spring cage comprises a second lip abutting the interior backplate;
wherein the interior backplate comprise a second opening aligned with the second lip; and
wherein the first plurality of wires and the second plurality of wires extend through the second opening.

8. The lockset of claim 1 , wherein the interior backplate includes a pair of lugs rotationally coupling the interior backplate to the chassis.

9. The lockset of claim 1 , wherein the interior assembly further comprises an interior window mounted on the interior escutcheon;
wherein the control assembly further comprises a wireless transceiver generally aligned with the interior window; and
wherein the control assembly is configured to wirelessly communicate with an external device via the wireless transceiver.

10. The lockset of claim 1 , further comprising a case housed in the interior escutcheon and a wire electrically coupled with the control assembly, wherein the case is configured to receive an energy storage device, and wherein the wire is configured to electrically couple the control assembly to the energy storage device.

11. The lockset of claim 10 , further comprising an energy storage device received within the case and electrically coupled to the control assembly.

12. The lockset of claim 1 , wherein the exterior spring cage comprises a first engagement feature;
wherein the exterior escutcheon comprises a second engagement feature; and
wherein the first and second engagement features are matingly engaged with one another and prevent rotation of the exterior escutcheon relative to the exterior spring cage.

13. An apparatus, comprising:
an assembly configured for mounting on an exterior surface of a door comprising a standard door preparation, the assembly comprising:
an escutcheon;
a spring cage seated in the escutcheon and rotationally coupled with the escutcheon, the spring cage defining a boundary between an inne
