Abstract

An electronic deadbolt assembly with a latch assembly having a bolt movable between an extended position and a retracted position. The deadbolt has an exterior assembly and an interior assembly. The exterior assembly has an electronic input device for entering a passcode and a wiring harness in electrical communication with the electronic input device. The interior assembly includes an electronic control assembly configured to move the bolt between the extended position and the retracted position responsive to an authorized passcode being entered in the electronic input device. The interior assembly has an electrical connector in electrical communication with the electronic control assembly that is configured to be connected with the connector on the exterior assembly

Claims

1. An electronic deadbolt assembly comprising:

a latch assembly with a bolt movable between an extended position and a retracted position;

an exterior assembly including an electronic input device for entering a passcode, wherein the exterior assembly includes a wiring harness in electrical communication with the electronic input device;

an interior assembly including a circuit board with a controller configured to control movement of the bolt between the extended position and the retracted position responsive to receiving an authorized passcode from the electronic input device; and

wherein the controller is in electrical communication with the electronic input device by an electrical connection between the wiring harness and an interior connector extending from the circuit board.

2. The electronic deadbolt assembly as recited in claim 1, wherein the interior connector includes a first end connected to the circuit board with a wire and a second end extending from the circuit board and configured to be connected with the wiring harness.

3. The electronic deadbolt assembly as recited in claim 2, wherein the interior connector extends out of the interior assembly.

4. The electronic deadbolt assembly as recited in claim 3, wherein the interior assembly includes a back plate defining an opening through which the interior connector extends.

5. The electronic deadbolt assembly as recited in claim 4, wherein the circuit board includes a first side and an opposing second side, wherein the interior connector is connected to a first side of the circuit board and extends from the second side through the opening in the back plate.

6. The electronic deadbolt assembly as recited in claim 5, wherein the interior assembly includes a cavity defined between the back plate and the circuit board that is dimensioned to receive at least a portion of the wiring harness.

7. An electronic deadbolt assembly comprising:

a latch assembly with a bolt movable between an extended position and a retracted position;

an exterior assembly including an electronic input device for entering a passcode;

an interior assembly including a controller in electrical communication with the electronic input device using a wiring harness, wherein the controller is configured to control movement of the bolt between the extended position and the retracted position responsive to receiving an authorized passcode from the electronic input device; and

a mounting bracket including a plate portion defining a pass-through dimensioned to receive the wiring harness and a plurality of spaced-apart tabs extending transversely from the plate portion, wherein the interior assembly includes threaded openings correspondingly positioned with openings in the plurality of tabs for connecting the interior assembly to the mounting bracket.

8. The electronic deadbolt assembly as recited in claim 7, wherein the interior assembly further comprises a back plate and an interior cover dimensioned to receive the back plate.

9. The electronic deadbolt assembly as recited in claim 8, wherein at least a portion of the plurality of tabs extend between the back plate and the interior cover.

10. The electronic deadbolt assembly as recited in claim 9, wherein the interior cover includes a plurality of threaded openings alignable with the tabs in the mounting bracket.

11. The electronic deadbolt assembly as recited in claim 10, wherein a portion of fasteners extend through the interior cover, tabs and back plate.

12. The electronic deadbolt assembly as recited in claim 7, further comprising:

an interior cover housing the interior assembly;

a turnpiece extending through an opening of the interior cover; and

a stem connected to both the turnpiece and an interior driver, the stem dimensioned to receive the turnpiece, wherein the interior driver is operably connected with the latch assembly.

13. The electronic deadbolt assembly as recited in claim 12, wherein the stem has a generally triangular shaped cross-section.

14. The electronic deadbolt assembly as recited in claim 7, wherein the interior assembly includes a transmission with a gear train having more than two gears.

15. The electronic deadbolt assembly as recited in claim 14, wherein the gear train includes three gears, wherein one of the three gears operably connected with the latch assembly.

16. An electronic deadbolt comprising:

a latch assembly including a bolt movable between an extended position and a retracted position;

an electronic input device configured to receive an input data;

a motor configured to move the bolt between the extended and retracted positions;

a controller configured to control actuation of the motor responsive to input data received from the electronic input device, wherein the controller is switchable between;

a single user mode in which the controller actuates the motor responsive to an authenticated user code; and

a master mode in which the controller actuates the motor responsive to an authenticated master code and an authenticated user code.

17. The electronic deadbolt as recited in claim 16, wherein the controller is configured to switch between the master mode and the single user mode responsive to input data received from the electronic input device.

18. The electronic deadbolt as recited in claim 16, wherein in the master mode, the controller is configured to add an additional authenticated user code responsive to input data received from the electronic input device.

19. The electronic deadbolt as recited in claim 16, wherein in the master mode, the controller is configured to delete an authenticated user code responsive to input data received from the electronic input device.

20. The electronic deadbolt as recited in claim 16, wherein in the single user mode, the controller is configured to prohibit adding additional authenticated user codes.
