Abstract: 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.
Abstract translation: 本发明是一种改进的多点门锁。 门闩用于安装在门的立柱上，并用于锁定到安装在相应的门侧柱上的相应的保持器。 多点门闩包括容纳第一和第二齿轮的壳体，每个齿轮可旋转地安装到壳体上，齿轮相互啮合以在第一和第二位置之间的相反方向旋转。 其中一个齿轮可安装到门锁杆上，以响应于门锁杆的移动而旋转。 门闩还包括枢转地安装到壳体的第一和第二钩，每个钩可在用于接合保持器的闩锁位置和非闩锁位置之间移动。 门闩还包括将第一和第二钩分别连接到第一和第二齿轮的致动器。 响应于齿轮在其第一和第二位置之间的旋转，致动器允许钩在其锁定位置和非闩锁位置之间移动。
