Abstract:
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.
