Abstract

An electronic lock assembly includes an exterior assembly, an interior assembly, and a latch having a deadbolt movable between an extended position and a retracted position, the latch being movable in response to rotation of a torque blade. The electronic lock includes a motor within the interior assembly and operable to rotate the torque blade, and a control circuit operatively connected to the motor and configured to selectively actuate the motor. A mortise insert includes a battery subassembly electrically connectable to the control circuit.

First claim

The invention claimed is:

1. An electronic lock installable at a door having an exterior side, an interior side, and an edge, the door having a mortise extending into the door from the edge and a borehole extending through the door from the interior side to the exterior side, the electronic lock comprising:
an exterior assembly mountable to the exterior side of the door at the borehole;
an interior assembly mountable to the interior side of the door at the borehole;
a latch positionable at least partially within the borehole and at least partially within the mortise, the latch having a deadbolt movable between an extended position and a retracted position, wherein in the extended position, the deadbolt extends from the edge of the door, and in the retracted position, the deadbolt retracts at least partially into the door;
a motor operatively connected to the latch to actuate the deadbolt between the extended position and the retracted position;
a control circuit operatively connected to the motor and configured to selectively actuate the motor to move the deadbolt between the retracted position and the extended position; and
a mortise insert mountable within the mortise, the mortise insert defining a housing, the mortise insert including a battery subassembly positioned within the housing, the battery subassembly electrically connected to the control circuit, the latch positioned at least partially within the housing, the battery subassembly being removable from the housing independent of the latch.

2. The electronic lock of claim 1 , wherein the battery subassembly is removable from the mortise at the edge of the door.

3. The electronic lock of claim 1 , wherein the mortise insert includes a mortise insert housing, and wherein the control circuit is positioned within the mortise insert housing, and wherein when the mortise insert is installed within the mortise, the control circuit and the mortise insert housing remain within the mortise when the battery subassembly is removed from the mortise.

4. The electronic lock of claim 1 , wherein the exterior assembly includes a keypad, the keypad being configured to receive an authentication code.

5. The electronic lock of claim 4 , wherein the control circuit is configured to, in response to receiving the authentication code from the keypad, actuate the motor to move the deadbolt from the extended position to the retracted position.

6. The electronic lock of claim 1 , wherein the deadbolt extends through a cross bore extending into the door from the edge of the door to the borehole, and wherein the mortise is positioned at least partially above the cross bore.

7. The electronic lock of claim 1 , wherein the motor is positioned at least partially within the borehole.

8. The electronic lock of claim 1 , wherein the motor is positioned within the interior assembly.

9. The electronic lock of claim 8 , wherein the control circuit is positioned within the interior assembly.

10. The electronic lock of claim 1 , further comprising a wireless interface operatively connected to the control circuit.

11. The electronic lock of claim 1 , further comprising a manual turnpiece included at the interior assembly.

12. An electronic lock comprising:
an exterior assembly mounted to an exterior side of a door at a borehole extending through the door from an interior side to the exterior side;
an interior assembly mounted to the interior side of the door at the borehole;
a latch positioned at least partially within the borehole and at least partially within a mortise, the latch having a deadbolt movable between an extended position and a retracted position, wherein, in the extended position, the deadbolt extends from an edge of the door, and in the retracted position, the deadbolt retracts at least partially into the door;
a motor operatively connected to the latch to actuate the latch between the extended position and the retracted position;
a control circuit operatively connected to the motor and configured to selectively actuate the motor to move the deadbolt between the retracted position and the extended position; and
a mortise insert mounted within the mortise, the mortise insert defining a housing extending into the door from the edge, the mortise insert including a battery subassembly positioned within the housing, the battery subassembly electrically connected to the control circuit, the latch positioned at least partially within the housing, and the battery subassembly being removable from the housing independent of the latch.

13. The electronic lock of claim 12 , further comprising a wireless communication interface operatively connected to the control circuit.

14. The electronic lock of claim 13 , wherein the wireless communication interface comprises a Bluetooth interface.

15. The electronic lock of claim 12 , wherein the exterior assembly includes a user interface configured to receive a credential.

16. The electronic lock of claim 12 , wherein the control circuit is included within the mortise insert.

17. The electronic lock of claim 12 , wherein the control circuit is included within the interior assembly.

18. The electronic lock of claim 12 , wherein at least one of: (i) the motor, (ii) a driving mechanism, (iii) circuitry, (iv) a chassis, or any combination of (i), (ii), (iii), and (iv), are positioned at least partially within the door.

19. An electronic lock assembly comprising:
an exterior assembly;
an interior assembly;
a latch having a deadbolt movable between an extended position and a retracted position, the latch being movable in response to rotation of a torque blade, the latch positioned at least partially within a mortise;
a motor included within the interior assembly and operable to rotate the torque blade;
a control circuit operatively connected to the motor and configured to selectively actuate the motor; and
a mortise insert mounted within the mortise, the mortise insert defining a housing, the mortise insert including a battery subassembly positioned within the housing, the battery subassembly electrically connectable to the control circuit, the latch positioned at least partially within the housing, the battery subassembly being removable from the housing independent of the latch.

20. The electronic lock assembly of claim 19 , wherein the control circuit is included in the mortise insert.

21. The electronic lock assembly of claim 19 , wherein the motor is included within the housing of the mortise insert.

22. The electronic lock assembly of claim 19 , wherein a wireless communication interface is positioned within the housing of the mortise insert.

23. The electronic lock assembly of claim 19 , wherein the control circuit, the motor, and a wireless communication interface are positioned within the housing of the mortise insert.
