Abstract
A door latch assembly includes a housing; a bolt configured to the extend from the housing in a first direction and retract into the housing in a second direction; a handle connected to the bolt; a lockable, blocking member configured to prevent movement of the bolt; a controller configured to place the door latch assembly into an overlock mode; an actuator in communication with the controller, the actuator configured to prevent movement of the bolt in the overlock mode.
Claims18
A door latch assembly comprising:
- a housing;
- a bolt configured to the extend from the housing in a first direction and retract into the housing in a second direction;
- a handle connected to the bolt;
- a lockable, blocking member configured to prevent movement of the bolt;
- a controller configured to place the door latch assembly into an overlock mode;
- an actuator in communication with the controller, the actuator configured to prevent movement of the bolt in the overlock mode;
- wherein the lockable, blocking member comprises:
- a base plate having a base plate tab extending from the base plate;
- an arm rotatably connected to the base plate, the arm including an arm tab extending from the arm;
- a base plate tab hole in the base plate tab;
- an arm tab hole in the arm tab;
- wherein the base plate tab hole and the arm tab hole are configured to be aligned with upon rotation of the arm relative to the base plate;
- a vibration sensor;
- wherein the controller is configured to place the door latch assembly into the overlock mode in response to the vibration sensor;
- wherein the controller is configured to send an attack message from the door latch assembly to a remote system in response to the sensed vibration.
