1. A door assembly for selectively interlocking first and second opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in a same rotary direction, the door assembly comprising:
a first door handle assembly operatively mounted to the first door at a latch side of the first door opposite the hinge side thereof, the first door handle assembly carrying at least one first interlocking element having an interlock surface, and
a second door handle assembly operatively mounted to the second door at a latch side of the second door opposite the hinge side thereof, the second door handle assembly carrying at least one second interlocking element having an interlock surface, the first and second door handle assemblies arranged relative to each other with the first at least one interlocking element aligned with the second at least one interlocking element such that the interlock surfaces of an aligned pair of the first and second interlocking elements can couple with one another,
wherein the aligned pair of the first and second interlocking elements can be misaligned by rotation of a door handle of one of the first and second door handle assemblies while the other of the first and second door handle assemblies is restricted from rotation by a stop element limiting rotation in one rotary direction so as to separate the first and second door handle assemblies.
