Abstract
A locking assembly including first and second hubs rotatably mounted in a case, a latch assembly which retracts in response to rotation of either of the hubs, and a locking member which selectively prevents rotation of at least one of the hubs. A sensor assembly is associated with at least one of the hubs, and is configured to transmit a signal in response to rotation of the at least one hub.
Claims21
A locking assembly, comprising:
- a case;
- a first hub rotatably mounted in the case and having a first home position and a first rotated position;
- a second hub rotatably mounted in the case and having a second home position and a second rotated position;
- a locking member aligned with the first hub and having a locking position wherein rotation of the first hub is prevented, and having an unlocking position wherein rotation of the first hub is enabled;
- a sensor assembly including:
- a first sensor associated with the first hub and operable to transmit a first signal in response to one of the first home position and the first rotated position;
- a second sensor associated with the second hub and operable to transmit a second signal in response to one of the second home position and the second rotated position;
- a third sensor associated with the locking member and operable to transmit a third signal in response to one of the locking position and the unlocking position;
- and
- a printed circuit board on which each of the first, second, and third sensors is mounted.
A sensor assembly operable to detect a condition of a locking assembly including a case which houses a first hub having a first home position and a first rotated position, a second hub having a second home position and a second rotated position, and a retraction assembly operable to retract a latch bolt in response to rotation of either of the first and second hubs, and wherein the case comprises an opening aligned with the first and second hubs, the sensor assembly comprising:
- a bracket configured for receipt within the opening;
- a sensor operable to transmit a signal in response to an actuating input;
- a first coupling operable to couple the sensor to the bracket;
- and
- a second coupling operable to couple the bracket to the case;
- and
- wherein the sensor assembly is structured for connection to the locking assembly in each of a first configuration and a second configuration;
- wherein, in the first configuration, the sensor is associated with the first hub, and the actuating input comprises one of the first home position and the first rotated position;
- and
- wherein, in the second configuration, the sensor is associated with the second hub, and the actuating input comprises one of the second home position and the second rotated position.
A system, comprising:
- a locking assembly including:
- a case defining an opening;
- first and second hubs rotatably mounted in the case and aligned with the opening, wherein each of the hubs is independently rotatable;
- a latch assembly biased to a locking position and having an unlocking position in response to rotation of either of the first and second hubs;
- and
- a locking element operable to selectively prevent rotation of the first hub;
- and
- a sensor assembly including a sensor operable to transmit a signal and structured to be received in the opening in a first configuration and a second configuration;
- and
- wherein, in the first configuration, the sensor is associated with the first hub and transmits the signal in response to rotation of the first hub;
- and
- wherein, in the second configuration, the sensor is associated with the second hub and transmits the signal in response to rotation of the second hub.
