Abstract
A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of a plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.
