ABSTRACT:
A hinge assembly capable of moving a panel or door between a flush, closed position and an outwardly opened position with at least 180 degrees of possible rotation of the panel. A housing is attached to the body at the edge of the door opening and locates a jack screw which drives a carriage in and out. On the carriage are located two idler shafts carrying fixed sprockets around which are wrapped a roller chain loop. The outer idler shaft is fixed to the panel and defines the hinge axis for the panel. One portion of the chain loop is fixed relative to the body such that, as the jack screw drives the hinge axis outwardly, the chain loop rotates the sprocket fixed to the outer idler shaft and the attached panel to an open position.
