Abstract

A deadbolt lock with an interior assembly having a status light indicator. The deadbolt assembly has a bolt movable between an extended position and a retracted position. An interior locking assembly includes a turnpiece configured to move the bolt between its extended position and retracted position, a light, and a detection circuit. The detection circuit is configured to detect when the bolt is in the extended position and actuate the light responsive to detecting that the bolt being in the extended position.

Claims

1. A deadbolt assembly comprising:

a bolt movable between an extended position and a retracted position;

an interior locking assembly defining an interior cavity, wherein the interior locking assembly includes;

a turnpiece configured to move the bolt between the extended position and the retracted position;

a light; and

a detection circuit disposed in the interior cavity and configured to detect when the bolt is in the extended position, wherein the detection circuit is configured to actuate the light responsive to detecting that the bolt is in the extended position.

2. The deadbolt assembly as recited in claim 1, further comprising a magnet movable with the turnpiece, wherein the detection circuit includes a magnetic sensor disposed in the interior cavity and is configured to actuate the light responsive to either:

(1) detecting the magnet;

or (2) detecting the absence of the magnet.

3. The deadbolt assembly as recited in claim 2, wherein the magnet is disposed in the interior cavity.

4. The deadbolt assembly as recited in claim 3, wherein the magnet is carried on a shank of the turnpiece.

5. The deadbolt assembly as recited in claim 4, further comprising a magnet carrier to which the magnet is attached, wherein the magnet carrier defines a passage dimensioned to receive the shank of the turnpiece.

6. The deadbolt assembly as recited in claim 4, wherein the magnet is movable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position.

7. The deadbolt assembly as recited in claim 6, wherein the magnet is positioned on the shank to be detectable by the magnetic sensor in the first position and undetectable by the magnetic sensor in the second position.

8. The deadbolt assembly as recited in claim 6, wherein the magnet is positioned on the shank to be undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.

9. The deadbolt assembly as recited in claim 2, wherein the magnetic sensor is a Hall effect sensor.

10. The deadbolt assembly as recited in claim 1, wherein the light is at least one LED.

11. The deadbolt assembly as recited in claim 1, wherein the interior locking assembly further comprises a rose defining a bore though which at least a portion of the turnpiece extends.

12. The deadbolt assembly as recited in claim 11, wherein the rose defines an opening and the light is positioned to illuminate through the opening.

13. The deadbolt assembly as recited in claim 11, wherein the interior locking assembly further comprises a battery holder, wherein at least a portion of the battery holder forms a substantially uninterrupted and continuous exterior surface with the rose.

14. A deadbolt assembly comprising:

a bolt movable between an extended position and a retracted position;

a turnpiece configured to move the bolt between the extended position and the retracted position;

a magnet movable with the turnpiece;

a magnetic sensor;

a light;

a processor electrically coupled with the light and magnetic sensor, wherein the processor is configured to actuate the light responsive to the magnetic sensor either;

(1) detecting the magnet;

or (2) detecting the absence of the magnet.

15. The deadbolt assembly as recited in claim 14, further comprising a rose defining a bore through which the turnpiece extends and a mounting plate, wherein the rose and the mounting plate define an interior cavity therebetween.

16. The deadbolt assembly as recited in claim 15, wherein the rose defines an opening and the light is positioned to illuminate through the opening.

17. The deadbolt assembly as recited in claim 15, further comprises a battery holder, wherein at least a portion of the battery holder forms a substantially uninterrupted and continuous exterior surface with the rose.

18. The deadbolt assembly as recited in claim 15, wherein at least one of the magnet, the processor and the light is disposed in the interior cavity.

19. The deadbolt assembly as recited in claim 14, wherein the magnet is carried on a shank of the turnpiece.

20. The deadbolt assembly as recited in claim 19, further comprising a magnet carrier to which the magnet is attached, wherein the magnet carrier defines a passage dimensioned to receive the shank of the turnpiece.

21. The deadbolt assembly as recited in claim 14, wherein the magnet is movable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position.

22. The deadbolt assembly as recited in claim 21, wherein the magnet is positioned on the shank to be detectable by the magnetic sensor in the first position and undetectable by the magnetic sensor in the second position.

23. The deadbolt assembly as recited in claim 21, wherein the magnet is positioned on the shank to be undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.

24. A deadbolt assembly comprising:

a bolt movable between an extended position and a retracted position;

an interior locking assembly defining an interior cavity, wherein the interior locking assembly includes;

a turnpiece configured to move the bolt between the extended position and the retracted position;

a light;

means for actuating the light responsive to the bolt being in the extended position, wherein the actuating means is entirely disposed in the interior cavity.

25. The deadbolt assembly as recited in claim 24, wherein the actuating means includes an electrical device disposed in the interior cavity that is configured to detect when the bolt is in the extended position.

26. The deadbolt assembly as recited in claim 25, further comprising a magnet movable with the turnpiece.

27. The deadbolt assembly as recited in claim 26, wherein the electrical device is a magnetic sensor configured to detect the magnet.

28. The deadbolt assembly as recited in claim 27, wherein the magnet is carried on a shank of the turnpiece.

29. The deadbolt assembly as recited in claim 28, further comprising a magnet carrier to which the magnet is attached, wherein the magnet carrier defines a passage dimensioned to receive the shank of the turnpiece.

30. The deadbolt assembly as recited in claim 26, wherein the magnet is movable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position.

31. The deadbolt assembly as recited in claim 30, wherein the magnet is positioned on the shank to be detectable by the magnetic sensor in the first position and undetectable by the magnetic sensor in the second position.

32. The deadbolt assembly as recited in claim 30, wherein the magnet is positioned on the shank to be undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.
