Door assembly for selectively interlocking opposing doors

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 a first plurality of interlocking elements each having an interlock surface,
• 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 a second plurality of interlocking elements each having an interlock surface, and
• wherein when the first plurality of interlocking elements are aligned in a complimentary arrangement with the second plurality of interlocking elements such that the first and second interlock surfaces of each aligned pair of the first and second pluralities of interlocking elements in the complimentary arrangement can couple,
• wherein the aligned pair of the first and second pluralities of 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.
