Dual action bifold door assembly

Year	Description
2000	Invention patented by Wade W Bryant, Dean N Rossman, and Edmond D Upton on January 9th, 2000. Abstract: A bifold door assembly includes two foldable door panels disposed in edge adjacent relation in a door closed position and including vertically spaced hinges connected adjacent center edges of the two panels and allowing folding motion of the panels between a longitudinally aligned closed position and alternative forward and rear pivoted side by side laterally extending open positions. Each of the door panels has an upper hinge member adjacent an outer edge of the respective panel and pivotable on carrier movable along a longitudinal upper track from a first position near one end of the track to a second position spaced inward from an opposite end of the track. At least one of the door panels also has a lower hinge member adjacent an outer edge of the respective panel and pivotably connected with carrier movable along a longitudinal lower track from a first position near one end of the track to a second position spaced longitudinally from said one end of the track. The door is capable of opening motion from either side by folding the door panels toward an opposite side by track guided longitudinal motion of the carrier of one of the panels with simultaneous pivoting motion of both panels about their hinge members while the carrier of the other panel remains stationary.
