Rolling door assembly having pass door arrangement
DCFirst Claim
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 flexible panel windable on and off said roller for movement into retracted and extended conditions, 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 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 defining a passage therethrough and a substantially vertical channel for guiding an edge region of said lower portion while in said first position;
a pass door movably 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 move frown said second position to said first position prior to extension of said flexible panel.

Abstract
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 conditions, 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, the pass door frame defining a passage therethrough and a substantially vertical channel for guiding an edge region of the flexible panel lower portion as it is extended. 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 prior to extension of the flexible panel.
