Abstract

An electronic deadbolt includes a face plate and a housing having a first end and an opposite second end. The first end is releasably coupled to the face plate, and the housing further includes a bolt compartment defining a bolt axis and a battery compartment defining a battery axis. The bolt axis is substantially parallel to and offset from the battery axis, and the bolt compartment is separated from the battery compartment proximate the second end of the housing. The electronic deadbolt further includes a bolt module disposed within the bolt compartment. The bolt module includes a motor and a deadbolt, and the deadbolt is configured to be selectively linearly extended from the face plate along the bolt axis.

Claims (32)

1. An electronic deadbolt comprising:

a face plate;

a housing comprising a first end and an opposite second end, wherein the first end is releasably coupled to the face plate, wherein the housing further comprises a bolt compartment defining a bolt axis and a battery compartment defining a battery axis, and wherein the bolt axis is substantially parallel to and offset from the battery axis, and the bolt compartment is separated from the battery compartment proximate the second end of the housing; and

a bolt module disposed within the bolt compartment, wherein the bolt module comprises a motor and a deadbolt, and wherein the deadbolt is configured to be selectively linearly extended from the face plate along the bolt axis.

2. The electronic deadbolt of claim 1 , wherein both of the bolt compartment and the battery compartment are substantially cylindrical.

3. The electronic deadbolt of claim 2 , wherein the bolt compartment has a first outer diameter and the battery compartment has a second outer diameter, and wherein the first outer diameter is approximately equal to the second outer diameter.

4. The electronic deadbolt of claim 2 , wherein the bolt compartment and the battery compartment are approximately 1¼ inches in diameter.

5. The electronic deadbolt of claim 1 , wherein the housing further comprises a spacer disposed at least partially between the bolt compartment and the battery compartment at the first end.

6. The electronic deadbolt of claim 1 , wherein the bolt module further comprises a lead screw configured to be rotated by the motor about the bolt axis, and wherein the deadbolt is coupled to the lead screw.

7. The electronic deadbolt of claim 6 , wherein the bolt module further comprises a support coupled to an inside surface of the bolt compartment, wherein the support is engaged with the deadbolt such that upon rotation of the lead screw, rotation of the deadbolt is prevented so that rotational movement of the lead screw is transferred into linear movement of the deadbolt.

8. The electronic deadbolt of claim 7 , wherein the support at least partially supports the motor and the deadbolt within the bolt compartment.

9. The electronic deadbolt of claim 1 , further comprising a substantially cylindrical cover threadably coupled to the face plate adjacent the battery compartment.

10. An electronic deadbolt comprising:

a bolt compartment having a bolt axis and configured to house a bolt module, wherein the bolt module comprises:

a motor;

a lead screw configured to be rotated by the motor about the bolt axis; and

a deadbolt coupled to the lead screw and upon rotation of the lead screw, is linearly extendable from the bolt compartment along the bolt axis;

a battery compartment having a battery axis and configured to house a battery module, wherein the bolt axis is substantially parallel to and offset from the battery axis; and

a face plate releasably coupled to the bolt compartment and the battery compartment.

11. The electronic deadbolt of claim 10 , wherein the bolt compartment and the battery compartment are coupled together to form a single housing.

12. The electronic deadbolt of claim 11 , wherein at least a portion of the bolt compartment and the battery compartment are separated by a gap.

13. The electronic deadbolt of claim 10 , wherein both of the bolt compartment and the battery compartment are substantially cylindrical.

14. The electronic deadbolt of claim 13 , wherein the bolt compartment has a first outer diameter and the battery compartment has a second outer diameter, and wherein the first outer diameter is approximately equal to the second outer diameter.

15. The electronic deadbolt of claim 13 , wherein the bolt compartment is independent from the battery compartment.

16. The electronic deadbolt of claim 10 , wherein the face plate comprises a shoulder extending therefrom and the compartments comprise a lip, and wherein when the compartments are coupled to the face plate the shoulder engages with the lip.

17. The electronic deadbolt of claim 10 , wherein the bolt compartment and the battery compartment are coupled to the face plate with a snap-fit connection.

18. The electronic deadbolt of claim 10 , wherein the bolt module further comprises a position sensor.

19. A method of installing an electronic deadbolt on a door, the method comprising:

boring two substantially cylindrical holes adjacent to one another on the door;

inserting at least a portion of the electronic deadbolt into the two cylindrical holes, wherein the electronic deadbolt includes a face plate and a housing including a bolt compartment and a battery compartment, wherein each compartment is inserted within a respective hole, and wherein a bolt module is disposed within the bolt compartment and a battery module is disposed within the battery compartment; and

securing the face plate to the door.

20. The method of claim 19 , further comprising inserting a power source into the battery compartment.
