Abstract
A screen closure for a garage doorway has a plurality of screened panels movable from an elevated, stored position in which such panels are side-by-side to an extended, operative position in which the panels extend vertically a distance sufficient to close the doorway. Those panels which are at eye level and below when the panels are in their extended position are substantially coplanar.

Apparatus for screening a doorway of selected area comprising
- a plurality of screen panels together having a combined area corresponding substantially to that of said doorway;
- a plurality of grooves accommodating said screen panels for movements between a stored position in which said screen panels are all positioned by an individual groove for each said screen panel and clear of and above said doorway, and an operative position in which said screen panels together screen said doorway;
- the plurality of grooves accommodating movement of said screen panels along paths relative to one another between said positions;
- wherein said screen panels when in said stored position are vertical, side-by-side and at substantially the same level;
- a plurality of hinges connecting a portion of said plurality of screen panels to one another for relative pivotal movement as said screen panels move from one of said positions toward the other of said positions;
- and
- a plurality of guides carried by each of said screen panels for guiding such screen panels in response to the movement thereof between said positions.

Apparatus slideably closing and opening a doorway formed by an upper, substantially horizontal header and a pair of parallel, spaced side frame members, a panel storage zone adjacent said header and above said doorway;
- a plurality of panels together having an area corresponding substantially to that of said doorway;
- wherein said panels when in said storage zone are vertical, side-by-side and at substantially the same level;
- a panel drive assembly for moving each of said plurality of panels from said storage zone downwardly to positions in which said plurality of panels together form a closure for said doorway;
- a pair of drive transmitting brackets for moving a first panel of said plurality of panels vertically between an elevated position in said panel storage zone to a lowered position in which said first panel of said plurality of panels closes an upper portion of said doorway;
- a pair of hoist cables for moving a second panel of said plurality of panels relative to said first panel of said plurality of panels from a position in said panel storage zone to a lowered position in which said second panel closes a second portion of said doorway;
- said pair of hoist cables and a first hinge for moving a third of said plurality of panels from a position in said storage zone and relative to said second panel to a lowered position in which said third panel closes a third portion of said doorway;
- a second hinge for moving a fourth panel of said plurality of panels from a position in said storage zone to a lowered position adjacent said third panel and in which said fourth panel closes a fourth portion of said doorway;
- a first guide reacting between said first panel and said frame members for guiding said first one of said panels from said raised position to said lowered position;
- the first hinge connecting said second panel to said third panel for enabling said third panel to swing from an elevated position to a lower position in response to movement of said second panel to said lowered position a second hinge connecting said third panel to said fourth panel enabling the latter to swing from a raised position to a lower position in response to movement of said third panel to its said lower position;
- and
- a plurality of guide rollers reacting between a first side frame member and a second side frame member as said third and fourth panels move to their respective lower positions for positioning said fourth panel beneath and substantially coplanar relative to said third panel.
