Claim:
A multiple panel, self-storing, vertical lift door system comprising: a first and a second single track guide rail, each guide rail having a vertical segment and a horizontal segment; a plurality of door panels, each panel having a front face, a back face, a top edge, a bottom edge, a first side edge, and a second side edge, each panel having a first guide roller supported on said first side edge, said first guide roller being engageable with said first guide rail so as to be displaceable therealong, each panel further including a second guide roller supported on said second side edge, said second guide roller being engageable with said second guide rail so as to be displaceable therealong; wherein when said guide rollers are engaged with the horizontal segment of their respective guide rails, they support said panels in a vertical relationship so that the bottom edges of the panels are in a coplanar relationship and the front edges of the panels are in a plane parallel relationship, and so that when the rollers are engaged with the vertical segment of their respective guide rails, they support said panels in a vertical relationship so that the front faces of the panels are in a coplanar relationship and the bottom edges of the panels are in a plane parallel relationship; a plurality of primary connector links disposed and operative to pivotally connect the first edge of one of said panels to the first edge of another, adjoining one of said panels, and the second edge of said one of said panels to the second edge of said adjoining one of said panels; a plurality of secondary connector links, each secondary connector link being pivotally affixed to one of said panels in a plane parallel relationship with a corresponding one of said primary connector links; and a drive system for moving said plurality of panels and their associated rollers along said first and second tracks between said vertical segment and said horizontal segment; whereby when said panels are disposed in said vertical segment, said door is in a closed position and when said panels are disposed in said horizontal segment, said door is in an open, storage, position.
