Abstract
Lock devices, systems, and methods including an internal mechanism to permit backdriven operation and lost motion operation. In one form, the lock includes an assembly of parts with locating features that 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 that can also be displaceable, in some embodiments, 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.
Claims2
-19. (canceled)
An apparatus, comprising:
- a motor structured to move a bolt of a door lock assembly between an extended position and a retracted position;
- a drive member drivingly coupled with the bolt and actuatable to cause movement of the bolt between the extended and retracted positions;
- and
- a lost motion assembly interposed between the motor and the drive member and having a first lost motion member moveable via the motor and a second lost motion member moveable via the drive member that is in moveable communication with the first lost motion member, the first lost motion member including a pocket that extends inwardly into the first lost motion member, the first lost motion member having an engaging portion structured to contact the second lost motion member within the pocket of the first lost motion member and cause movement of the drive member between a relatively extended position and a relatively retracted position, the first lost motion member also having a range of motion in which the engaging portion is not in contact with the second lost motion member within the pocket of the first lost motion member.
