Claim:
A high-speed door assembly for selectively permitting and prohibiting access through an opening in a wall, or other blocking structure, the opening having a width, comprising: a shaft or drum located proximate the wall or other blocking structure and being outside of the opening, and the shaft or drum having a longitudinal axis which is configured so that the longitudinal axis is parallel with the wall or other blocking structure in which the opening is formed; a flexible door panel 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 the opening, 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 farther from the wall than the longitudinal axis of the shaft or drum is spaced from the wall or other blocking structure; a first guide operatively mounted proximate the opening and having opposed surfaces between which a portion of the door panel is guided during opening and closing and wherein at least a portion of the opposed surfaces extends into the opening; a second guide operatively mounted proximate the opening and having opposed surfaces between which a portion of the door panel is guided during opening and closing and wherein at least a portion of the opposed surfaces extends into the opening; and, a guide moving assembly being operatively connected to at least one of the first or second guides, where, in conjunction with opening and closing of the door panel, at least a portion of the at least first or second guides is movable between a first position and a second position wherein the at least first or second guides extend operatively into the opening in the first position to guide the door panel, and a portion of the at least first or second guide does not significantly extend into the opening in the second position.
