摘要:
The present invention is an improved multi-point door latch. The door latch is for mounting in a stile of a door and for latching to a corresponding keeper mounted in a corresponding door jamb. The multi-point door latch includes a housing containing first and second gears, each gear being rotatably mounted to the housing, the gears intermeshing to rotate in opposite directions between first and second positions. One of the gears is mountable to a door lock lever to rotate in response to movement of the door lock lever. The door latch also includes a first and second hook pivotally mounted to the housing, each hook being movable between a latching position for engaging the keeper and a non-latching position. The door latch also includes an actuator coupling the first and second hooks to the first and second gears, respectively. The actuator permits the hooks to move between their latching and non-latching positions in response to the rotation of the gears between their first and second positions, respectively.
