    Patent number: 6637044
    Abstract: A toilet trip lever assembly provides a lever arm that extends in the tank perpendicular to the tank wall. As an outer handle is rotated, it drives a stem, which in turn drives an arm inside the tank that extends parallel to the tank wall, which pushes down an end of a lever. A support holds the lever such that downward movement of that end of the lever drives the opposite end of the lever up. The opposite end of the lever is connected to a linkage to a flush valve.
    Type: Grant
