Abstract

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

First claim

What is claimed is:

1. An electronic lock system, comprising:
an interchangeable electrical connector selected from a plurality of differently configured interchangeable electrical connectors including a first electrical connector configured with a first preselected connection of wires and a second electrical connector configured with a second preselected connection of wires that is configured differently from the first electrical connector; and,
a lock configured to perform a predetermined plurality of functions with each function of the plurality of functions being different from one another, the lock including a predetermined plurality of sensors and actuators configured to enable the predetermined plurality of functions, the lock configured to perform one or more of the predetermined plurality of functions in response to a predetermined actuation of one or more of the sensors and actuators, the lock being connectable with each of the differently configured interchangeable electrical connectors to enable the lock to perform different functions depending on the selected one of the plurality of differently configured interchangeable electrical connectors connected to the lock, wherein the lock is connectable with the first electrical connector and configured to perform a first function when connected with the first electrical connector and wherein the lock is connectable with the second electrical connector and configured to perform a second function when connected with the second electrical connector, the first function being different from the second function.

2. The electronic lock system of claim 1 , wherein the lock comprises a lock housing.

3. The electronic lock system of claim 2 , wherein the predetermined plurality of actuators are disposed within the lock housing.

4. The electronic lock system of claim 3 , wherein the predetermined plurality of sensors are disposed within the lock housing and wherein the predetermined plurality of actuators are configured to activate in response to signals from the predetermined plurality of sensors.

5. The electronic lock system of claim 2 , wherein the lock comprises a locking mechanism disposed within the lock housing, the locking mechanism being moveable between latched and unlatched positions.

6. The electronic lock system of claim 5 , wherein the predetermined plurality of sensors sense one or more parameters selected from the group of a parameter indicating that the locking mechanism is in the latched position, a parameter indicating that the locking mechanism is in the unlatched position, a parameter indicating that the interchangeable electrical connector is connected to the lock, a parameter indicating that the interchangeable electrical connector is disconnected from the lock, a parameter indicating that a handle is rotated, and a parameter indicating that a cover is removed.

7. The electronic lock system of claim 2 , further comprising a circuit board, wherein the circuit board is disposed inside the lock housing.

8. The electronic lock system of claim 1 , further comprising an external control unit, wherein the external control unit is configured to control operation of the lock.

9. The electronic lock system of claim 8 , wherein the external control unit comprises an alarm and is configured to monitor signals from the predetermined plurality of sensors, wherein the external control unit activates the alarm upon detecting a predetermined subset of the signals.

10. The electronic lock system of claim 8 , wherein the external control unit comprises an authentication input device configured to recognize a user input, wherein the authentication input device is selected from the group of a card key reader, a proximity detector, a keypad, a fingerprint sensor, an iris scanner, and a voice recognition sensor.

11. A method of upgrading a lock, comprising:
selecting an interchangeable electrical connector from a plurality of differently configured interchangeable electrical connectors including a first electrical connector configured with a first preselected connection of wires and a second electrical connector configured with a second preselected connection of wires that is configured differently from the first electrical connector;
providing a lock configured to perform a predetermined plurality of functions with each function of the plurality of functions being different from one another, the lock including a predetermined plurality of sensors and actuators configured to enable the predetermined plurality of functions, the lock configured to perform one or more of the predetermined plurality of functions in response to a predetermined actuation of one or more of the sensors and actuators, the lock being connectable with each of the differently configured interchangeable electrical connectors to enable the lock to perform different functions depending on the selected one of the plurality of differently configured interchangeable electrical connectors connected to the lock; and,
connecting the lock with the first electrical connector to enable the lock to perform a first function, alternatively connecting the lock with the second electrical connector to enable the lock to perform a second function that is different from the first function.

12. The method of claim 11 , further comprising:
connecting the lock with the first electrical connector to enable the lock to perform the first function;
disconnecting the lock from the first electrical connector;
connecting the lock with the second electrical connector to enable the lock to perform the second function that is different from the first function.
