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 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 an actuating force causing 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 and is configured to rotate in response to an external actuating force applied thereto;
- 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.
A mortise lockset, comprising:
- a case including an opening;
- a first hub rotatably mounted in the case, wherein the first hub is configured to rotate in response to actuation of a first handle;
- a second hub rotatably mounted in the case, wherein the second hub is configured to rotate in response to actuation of a second handle, and wherein the first hub and the second hub are independently rotatable;
- a latchbolt movably mounted to the case, the latchbolt having an extended position and a retracted position;
- a retraction assembly engaged with the latchbolt, the first hub, and the second hub, wherein the retraction assembly is configured to retract the latchbolt in response to rotation of the first hub by the first handle, and wherein the retraction assembly is configured to retract the latchbolt in response to rotation of the second hub by the second handle;
- and
- a sensor assembly comprising a bracket mounted to the case and a sensor mounted to the bracket, wherein the sensor assembly extends into the case via the opening, and wherein the sensor is operable to selectively transmit a signal indicative of an attempt to retract the latchbolt;
- wherein the sensor assembly is selectively mountable to the case in each of a first configuration and a second configuration;
- wherein with the sensor assembly mounted to the case in the first configuration, the sensor is configured to transmit the signal in response to rotation of the first hub by the first handle;
- and
- wherein with the sensor assembly mounted to the case in the second configuration, the sensor is configured to transmit the signal in response to rotation of the second hub by the second handle.
