1. A door latch assembly, comprising:
a latch comprising a bolt reciprocable in a vertical direction from an extended, latched position to a retracted, unlatched position and from the retracted, unlatched position to the extended, latched position along a reciprocation axis; and
a rotatable input rotatable about the substantially vertical direction, the rotatable input having a rotatable input latched position and a rotatable input unlatched position, the rotatable input rotatable about the vertical direction from the rotatable input latched position to the rotatable input unlatched position and from the rotatable input unlatched position to the rotatable input latched position, the rotatable input maintaining the latch in the latched position when the rotatable input maintains the rotatable input latched position; and
a crank link rotatable in response to a rotation of the rotatable input, wherein the crank link rotates on a crank link rotation axis orthogonal to the vertical direction.
