摘要： A rolling door assembly for selectively covering an opening in a building includes a shutter roller rotatable about a substantially horizontal axis and a flexible panel windable on and off the roller for movement into retracted and extended positions, respectively. The flexible panel defines an upper portion having a first width and a lower portion having a second width less than the first width. At least one pass door frame is hingedly securable proximate a lateral side of the opening for movement between a first position, in which the pass door frame extends in a substantially transverse direction relative to the opening and a second position, in which the pass door frame is substantially aligned with the at least one sidewall. A pass door is movably mounted within the passage defined by the pass door frame to selectively provide ingress and egress therethrough and a closure system is provided for causing the pass door frame to move from the second position to the first position after extension of the flexible panel.
