Abstract

Lock devices, systems, and methods that can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock includes an assembly of parts that includes parts having locating features that that can assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components of the can also be displaceable, in at least certain situations, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

Claims

1-19. -19. (canceled)

20. An apparatus, comprising:

a housing having an inner bolt housing and a cam housing, the cam housing being telescopically coupled to the inner bolt housing, the cam housing including a first housing feature;

a bolt having an aperture, a portion of the bolt positioned within the inner bolt housing;

a cam having an extension, a first cam feature, and an aperture, the aperture sized for receipt of a complementary shaped driver; and

wherein the first housing feature and the cam first feature are configured to prohibit the cam from being rotably coupled to the cam housing at more than a single orientation relative to the cam housing, and wherein the extension is engaged with the aperture of the bolt when the cam is rotably coupled to the cam housing at the single orientation.

21. The apparatus of claim 20, wherein the first cam feature of the cam is a first protrusion extending from a first sidewall of the cam, the first protrusion sized to be received in the cam housing in only a first opening located on a first sidewall of the cam housing.

22. The apparatus of claim 21, wherein the cam further includes a second cam feature comprising a second protrusion, the second protrusion extending from a second sidewall of the cam, and wherein the cam housing includes a second housing feature comprising a second opening, the second opening sized to (a) receive the second protrusion, and (b) not receive the first protrusion.

23. The apparatus of claim 20, further including the complementary shaped driver and a lock cylinder assembly, the complementary shaped driver being coupled to the lock cylinder assembly.

24. The apparatus of claim 23, wherein the lock cylinder assembly includes a post structured to limit rotation of the complementary shaped driver.

25. The apparatus of claim 20, further comprising an electric motor, a gear train, and a member structured to interact with an output of the gear train and having an opening for receiving the complementary shaped driver.

26. An apparatus, comprising:

a deadbolt assembly having a housing that encloses a portion of a bolt; and

a cam having a cam feature structured to interact with an assembly feature of the deadbolt assembly to prohibit the cam from being rotably securable to the housing at more than a single orientation of the cam relative to the housing and in a manner in which rotation of the cam facilitates linear displacement of the bolt relative to the housing.

27. The apparatus of claim 26, wherein the cam feature is an opening positioned on only one side of the cam, and wherein the assembly feature is a locating feature of a drive member of the deadbolt assembly.

28. The apparatus of claim 27, wherein the cam further includes one or more first surface features, and wherein a first side of the housing includes a first side feature, the first side feature sized to mate with the one or more first surface features.

29. The apparatus of claim 28, wherein the cam further includes one or more second surface features, and wherein a second side of the housing includes a second side feature, the second side feature sized to mate with the one or more second surface features but not with the one or more first side features.

30. The apparatus of claim 28, wherein the cam is rotatable between a first position and a second position by rotation of the drive member that is received in the opening, the opening of the cam being in a horizontal position that is generally aligned with a horizontal position of the bolt when the cam is in the second position, wherein an extension of the cam is pointed away from the bolt of the deadbolt assembly when the-cam is in the second position.

31. The apparatus of claim 30, wherein the first side feature is a first opening and the second side feature is a second opening, each of the first and second openings including an entrance through which a portion of the cam can be slidingly received, and each entrance having a unique size.

32. The apparatus of claim 26, further comprising a drive member and a thumbturn, the drive member having a location feature, the cam having an aperture structured to receive the drive member, the aperture including a formation sized to receive insertion of the locating feature when the drive member is received at one, and only one, orientation relative to the aperture, and wherein a horizontal position of the drive member represents a bolt retracted position.

33. A method, comprising:

moving a door bolt cam and a door bolt housing into a pre-installation orientation;

manipulating a relative orientation of the door bolt cam and the door bolt housing to align;

a first cam feature of the door bolt cam with respect to a first housing feature the door bolt housing, and

a second cam feature of the door bolt cam with respect to a second housing feature the door bolt housing, the second cam feature having a configuration that prevents alignment of the second cam with the first housing feature;

wherein the manipulating results in only one possible orientation of the door bolt cam relative to the door bolt housing; and

as a result of the manipulating, inserting the door bolt cam into the door bolt housing such that the door bolt cam is installed into the door bolt housing in one orientation.

34. The method of claim 33, further comprising engaging a drive member having a poka-yoke feature with the door bolt cam having a complementary poka-yoke feature.

35. The method of claim 34, further comprising coupling a thumbturn to the drive member.

36. The method of claim 35, wherein the thumbturn is structured to receive the poka-yoke feature of the drive member in only one attitude, which further includes inserting a portion of the drive member into an opening of a lost motion member.

37. The method of claim 35, wherein the inserting is accomplished by orienting the drive member in only one way.

38. The method of claim 35, further comprising engaging a gearing of a door assembly with the lost motion member and installing a motor used to drive the gearing.

39. The method of claim 38, wherein the first cam feature is a protrusion and the first housing feature is an aperture.
