Abstract
A high-speed door assembly has a shaft or drum having a longitudinal axis which is configured so that the longitudinal axis is parallel with a wall to which the door assembly is mounted. A flexible door panel is attached to the shaft or drum so as to be capable of being wound and unwound about the drum for selectively permitting and prohibiting access through an opening in the wall to which the door assembly is mounted, the door panel being wound on the shaft or drum in an orientation such that the door panel defines at least one vertical plane when unwound from the shaft or drum, the vertical plane being spaced further from the wall to which the door assembly is mounted than the longitudinal axis of the shaft or drum. The door panel preferably having at least a portion of its width being substantially equal to or less than the width of the opening and is preferably used with guides which extend into the width of an opening passage of a door while being able to retreat, retract or collapse from their position extended into the door width upon experiencing an impact by an atypical force which can dislodge the door panel from the guides.
