Abstract
An angulated door assembly affording reduced entry and exit time and motion therethrough. Each door is angulated relative to the adjacent walls and/or the conventional path of ingress/egress therethrough. Such an assembly configuration affords increased sealing capacity as well as convenience for the user. The door opens and closes faster by swinging less than a conventional door, which presents itself orthogonally to the path of ingress/egress. By utilizing a pair of angulated doorways, the doors self-seal against each other while providing the advantages of angulated disposition relative to the path of ingress/egress.
