1. A lock system, comprising:
- a housing configured for mounting to a door;
a manually operable member mounted for rotation relative to the housing;
a driver mounted for rotation relative to the housing;
an adapter mounted for joint rotation with one of the manually operable member or the driver, the adapter including a plurality of notches;
a clutching cam mounted for joint rotation with the other of the manually operable member or the driver;
a pin movably mounted to the clutching cam, the pin having a disengaged position in which the pin does not rotationally couple the clutching cam and the adapter, and the pin having an engaged position in which the pin extends into one of the notches and rotationally couples the clutching cam and the adapter, wherein the pin is biased toward the disengaged position;
a wall including an arcuate cam surface, the wall having a first position in which the arcuate cam surface supports the pin in the disengaged position, the wall having a second position in which the arcuate cam surface retains the pin in the engaged position, thereby rotationally coupling the adapter and the clutching cam;
a coil spring engaged with the wall such that rotation of the coil spring in a first direction urges the wall from the first position toward the second position and such that rotation of the coil spring in a second direction urges the wall from the second position toward the first position; and
a motor mounted in the housing, the motor including an output shaft drivingly connected to the coil spring;
wherein the motor is configured to rotate the coil spring in the first direction in response to receiving a first signal, thereby urging the wall toward the second position such that the wall urges the pin toward the engaged position in which the pin extends into one of the notches and rotationally couples the clutching cam and the adapter, thereby rotationally coupling the manually operable member and the driver; and
wherein the motor is configured to rotate the coil spring in the second direction in response to receiving a second signal, thereby urging the wall toward the first position such that the wall supports the pin in the disengaged position, thereby permitting relative rotation of the adapter and the clutching cam, thereby permitting relative rotation of the manually operable member and the driver.

Abstract
A deadbolt lock assembly including a retractable and extendable deadbolt, a housing, an outside member movably mounted on the housing and being normally disconnected from the deadbolt, and an operator input device on the housing, with the operator input device connecting the member to the deadbolt in response to presentation of an appropriate credential, such that a force applied to the member by the operator is mechanically transmitted to the deadbolt to move the deadbolt.

10. A lock system, comprising:
-
a housing; a bolt mounted for movement relative to the housing between an extended position and a retracted position; an operating member mounted for rotation relative to the housing, the operating member being normally disconnected from the bolt; a clutch assembly operable to selectively connect the operating member to the bolt, the clutch assembly having a disconnecting state in which the operating member remains disconnected from the bolt, and the clutch assembly having a connecting state in which the operating member is connected to the bolt such that a force applied to the outside member by an operator is mechanically transmitted to the bolt to move the bolt from the extended position to the retracted position; and a motor operable to move the clutch assembly between the disconnecting state and the connecting state, wherein the motor is configured to move the clutch assembly to the connecting state in response to a first signal, and wherein the motor is configured to move the clutch assembly to the disconnecting state in response to a second signal; wherein with the operating member disconnected from the deadbolt, the operating member has a plurality of rotational positions in which the clutch assembly operable to connect the member to the bolt. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
