Abstract

A deadbolt lock assembly comprising a retractable and extendable deadbolt, a housing, an outside member movably mounted on the housing, the member being normally disconnected from the deadbolt, and an operator input device on the housing, the 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.

Claims

1. A deadbolt lock assembly comprising

a retractable and extendable deadbolt,

a housing,

a credential reading device on the housing,

an outside turnpiece pivotally mounted on the housing, the turnpiece being normally disconnected from the deadbolt, and the turnpiece being configured to be gripped and turned by an operator,

a key operated lock mechanism on the housing, and

a mechanism operable to connect the turnpiece to the deadbolt so that an operator can turn the turnpiece to move the deadbolt, the mechanism connecting the turnpiece to the deadbolt both when an operator uses a key in the key operated lock mechanism and when an operator presents an appropriate credential to the credential reading device, only one of the key and the credential being required for the mechanism to connect the turnpiece to the deadbolt.

2. A deadbolt lock assembly as set forth in claim 1 and further comprising a driver bar pivotally mounted on the housing and operably connected to the deadbolt, and wherein the mechanism is operable to connect the turnpiece to the driver bar both when an operator uses a key in the key operated lock mechanism and when an operator presents an appropriate credential to the credential reading device.

3. A deadbolt lock assembly as set forth in claim 2 and further comprising a motor and a controller receiving input from the credential reading device and sending a signal to the motor to connect the turnpiece to the driver bar.

4. A deadbolt lock assembly as set forth in claim 3 and further comprising a wall movable relative to the housing, an adapter connected to the turnpiece for movement therewith, the adapter having therein a notch, and a pin movable into the notch, wherein the motor moves the wall, thereby causing the wall to move the pin into the notch, thereby connecting the adapter to the driver bar.

5. A deadbolt lock assembly as set forth in claim 4 and further comprising a clutching cam connected to the driver bar for movement therewith, the pin being mounted on the clutching cam for movement relative thereto with respect to the adapter, and the pin being mounted on the clutching cam for pivotal movement therewith such that when the pin extends into the notch in the adapter, pivotal movement of the adapter causes pivotal movement of the clutching cam, and such that when the pin does not extend into the notch in the adapter, pivotal movement of the adapter does not cause pivotal movement of the clutching cam.

6. A deadbolt lock assembly as set forth in claim 5 wherein the adapter has therein a plurality of notches spaced around the adapter, and wherein the pin is movable into any one of the notches, depending on the relative positions of the adapter and the clutching cam, so that pivotal movement of the adapter causes pivotal movement of the clutching cam when the pin extends into any one of the notches.

7. A deadbolt lock assembly as set forth in claim 5 wherein the key operated lock mechanism is mounted on the turnpiece, wherein the clutching cam has therein a recess, and wherein the key operated lock mechanism includes an inner portion pivotable relative to the turnpiece with the key after the key is inserted into the key operated lock mechanism, the inner portion having thereon a member extendable into the recess only after the key is turned relative to the turnpiece, whereby the turnpiece is connected to the driver bar and thereby to the deadbolt when an operator turns the key and thereafter pushes the key inward.

8. A deadbolt lock assembly as set forth in claim 7 wherein the member is collapsible such that pushing the key or lock inward without turning the key collapses the member rather than forcing the member into the recess.

9. A deadbolt lock assembly as set forth in claim 3 and further comprising an inside turnpiece operably connected to the driver bar for pivotal movement therewith, and wherein the controller, after an operator turns the inside turnpiece to retract the deadbolt, sends a signal to the motor to connect the outside turnpiece to the driver bar, and initiates a relock time delay to give an operator a predetermined amount of time to relock the deadbolt with the outside turnpiece.

10. A deadbolt lock assembly as set forth in claim 3 and further comprising an inside turnpiece connected to the driver bar for pivotal movement therewith, and wherein the controller, after an operator turns the inside turnpiece to retract the deadbolt, sends a signal to the motor to connect the outside turnpiece to the driver bar, and initiates an indefinite relock time delay to give an operator an indefinite amount of time to relock the deadbolt with the outside turnpiece.
