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.

The invention claimed is: 1. A fire door assembly for protecting a building opening defined by at least one lateral sidewall, comprising: a shutter roller rotatable about a substantially horizontal axis; means for rotating said shutter roller; a pair of alignment rails, with each rail positioned on a side of the building opening; a flexible panel windable on and off said shutter roller for movement of said flexible panel into retracted and extended positions, respectively, said flexible panel defining an upper portion having a first width and a lower portion having a second width less than said first width, a leading edge of the lower portion having an aligning member secured thereto, said aligning member having ends guidable in said alignment rails, the aligning member being proximate to the floor when the flexible panel is in the extended position; a pass door frame hingedly securable proximate a lateral side of the opening for movement between a first position in which said pass door frame extends in a substantially transverse direction relative to the opening, and a second position in which said pass door frame is substantially aligned with said at least one sidewall, said pass door frame having a vertical overlap region extending over a vertical edge of a first side of said lower portion of said flexible panel when said flexible panel is in said extended position and said pass door frame is in said first position, said pass door frame having a movable overlap member movably mounted to a side opposite a side of said vertical overlap region, said movable overlap member being selectively movable from an undeployed position to a deployed position over said vertical edge along a second side of said lower portion of said flexible panel opposite said first side, so that when said movable overlap member is in said deployed position, said vertical edge is positioned between said vertical overlap region and said movable overlap member; a movable member release means connected to one of said pass door frame and said flexible panel, to cause said movable overlap member to move to the deployed position; a pass door moveably mounted within the passage defined by said pass door frame to selectively provide ingress and egress therethrough; and closure means for causing said pass door frame to be positioned in said first position after said flexible panel is in the extended position. 2. The fire door assembly of claim 1, wherein said closure means includes means for biasing said pass door frame into said first position and pass door releasable means for releasably retaining said pass door frame in said second position. 3. The fire door assembly of claim 2, wherein said pass door releasable means is responsive to an externally supplied signal to release said pass door frame, thereby allowing said pass door frame to move into said first position. 4. The fire door assembly of claim 2, wherein said pass door releasable means is an electromagnetic device. 5. The fire door assembly of claim 2, further including trigger means activated by movement of said flexible panel, said pass door releasable means being responsive to said trigger means to release said pass door frame. 6. The fire door assembly of claim 5, wherein said trigger means is positioned in one of said alignment rails and causes said pass door releasable means to release said pass door frame. 7. The fire door assembly of claim 1, further comprising means for detecting a fire and wherein said means for rotating said shutter roller is responsive to said fire detecting means to complete extension of said flexible panel prior to said pass door frame moving into said first position. 8. The fire door assembly of claim 1, wherein said closure means is responsive to an externally supplied signal to move said pass door frame from said second position into said first position. 9. The fire door assembly of claim 1, further including hinge means for hingedly securing said pass door frame proximate said lateral sidewall. 10. The fire door assembly of claim 1, wherein said vertical overlap region comprises magnetic means for attracting said vertical edge of said first side of said lower portion of said flexible panel. 11. The fire door assembly of claim 10, further comprising a horizontal overlap region at a top of said pass door frame for overlapping a bottom edge of said upper portion of said flexible panel when said flexible panel is in the extended condition. 12. The fire door assembly of claim 1, wherein said member release means comprises a retractable plunger assembly movable to a retracted position when said pass door frame is moved proximate said aligning member. 13. The fire door assembly of claim 12, wherein a bottom edge of said overlap member is supported by said retractable plunger assembly when said overlap member is in said undeployed position. 14. The fire door assembly of claim 13, further comprising an obstruction on said aligning member at a position opposite said retractable plunger assembly to cause said retractable plunger assembly to retract upon engagement of said obstruction and said retractable plunger assembly. 15. The fire door assembly of claim 1, further including a second pass door frame hingedly securable proximate a second lateral side of the opening for movement between a first position, in which said second pass door frame extends in a substantially transverse direction relative to the opening and a second position, in which said second pass door frame is substantially aligned with a second sidewall opposite said at least one sidewall, said second pass door frame having a vertical overlap region extending over a second vertical edge of a first side of said lower portion of said flexible panel when said flexible panel is in said extended position and said second pass door frame is in said first position, said second pass door frame having a movable overlap member movably mounted to a side opposite a side of said second vertical overlap region, said movable overlap member being selectively movable from an undeployed position to a deployed position over said second vertical edge along a second side of said lower portion of said flexible panel opposite said first side, so that when said movable overlap member of said second pass door frame is in said deployed position, said second vertical edge is positioned between said vertical overlap region and said movable overlap member of said second pass door frame; a second pass door movably mounted within the passage defined by said second pass door frame to selectively provide ingress and egress therethrough; and second closure means for causing said second pass door frame to be positioned in said first position after said flexible panel is in the extended position. 16. The fire door assembly of claim 15, wherein a sum of widths of said first and second pass door frames does not exceed a difference between the first width and second width. 17. The fire door assembly of claim 16, wherein said first and second pass door frames are of the same width. 18. The fire door assembly of claim 1, further including means for hingedly securing said pass door to said pass door frame. 19. The fire door assembly of claim 1, wherein the movable member release means connected to one of said pass door frame and said flexible panel causes said movable overlap member to move to the deployed position in response to the flexible panel being in the extended position and the pass door frame being in the first position.
