  • Failsafe electric locking lever trim
    Patent number: 5484179
    Abstract: A door lever assembly for disengaging an unlocked latch of a lockable door latch assembly includes a lever handle rotatably connected to a trim housing and a cam operably connected to the lever handle. The cam is positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of a movable slider positioned adjacent to the cam. An electrically activated block arm is positionable to prevent movement of the movable slider, effectively locking the door lever assembly.
