Patent ID: 8857498

Claim:
A door system, comprising: a flexible panel having a first surface and a second surface opposite the first surface, the panel to be movable between an open position and a closed position, the panel including a fabric sheet and a planar drive strip defining a plane, the drive strip affixed to a lateral edge of the panel, the drive strip unitarily extending between a top edge and a bottom edge of the panel; a plurality of projections separately formed from and disposed on the drive strip adjacent the lateral edge of the panel, the plurality of projections spaced apart to expose segments of the drive strip between adjacent projections on first and second sides of the drive strip corresponding to the first and second surfaces of the flexible panel, the plurality of projections comprising a first portion and a second portion, the first portion projecting substantially perpendicularly relative to the first surface and the second portion projecting substantially perpendicularly relative to the second surface, the portions of the plurality of projections to extend into a channel of a track; a storage track comprising a scroll slot, the scroll slot to be more narrow than a width of the projections in a direction perpendicular to a plane of the panel to retain the projections within the storage track when the panel is in the open position; and a drive gear to engage at least one of the first portion or the second portion of the plurality of projections without crossing the plane defined by the drive strip to move the panel, a rigidity of the drive strip sufficient to transmit a force from the drive gear along the drive strip to move the top and bottom edges of the panel as the panel moves from the closed position to the open position.
