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.

Door latch

A lever apparatus having a lever connected to a latch assembly operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.
