Abstract: A latch assembly that is adjustable between first and second backset settings. A cam is rotatable about a cam axis, and facilitates linear displacement of a latch link in a first direction. A multiplier link is rotatable about a multiplier link axis that is offset from the cam axis can be rotated in the first rotational direction by engagement with the latch link. A latch bar is coupled to the multiplier link and is linearly displaced in a second direction by rotation of the multiplier link in the first direction. The latch apparatus also includes a latch bolt that is coupled to the latch bar, the latch bolt being displaced toward a retracted position by the displacement of the latch bar in the second direction. The latch assembly can also include a dead latch link can block retraction of at least the latch bolt.
