<p>A rolling door assembly (10) for selectively covering an opening in a building includes a shutter roller (12) rotatable about a substantially horizontal axis and a flexible panel (16) windable on and off the roller (12) for movement into retracted and extended conditions, respectively. The flexible panel (16) defines an upper portion (16a) having a first width (W1) and a lower portion (16b) having a second width (W2) less than the first width (W1). At least one pass door frame (20) is hingedly securable proximate a lateral side of the opening for movement between a first position, in which the pass door frame (20) extends in a substantially transverse direction relative to the opening and a second position, in which the pass door frame (20) is substantially aligned with the sidewall (60), the pass door frame (20) defining a passage therethrough and a substantially vertical channel (20a) for guiding an edge region of the flexible panel lower portion (16b) as it is extended. A pass door (28) is movably mounted within the passage defined by the pass door frame (20) to selectively provide ingress and egress therethrough and a closure system is provided for causing the pass door frame (20) to move from the second position to the first position prior to extension of the flexible panel (16).</p> |
