ABSTRACT:
A top hinged swinging sash assembly includes a hinge bar adapted for securement to a building girt, said hinge bar including a substantially J-shaped hinge rail. A frame assembly comprising a head member, a sill member, two or more vertical mullions and two side flashing members is joined to the hinge bar through a curved, beaded head rail extending from the head member. The spaced, vertical mullions connect between the head and sill members with flat or corrugated panels being retained between the mullions and mullion caps mounted thereto. Operators connect to the frame and preferably to the mullions or sills to cause the frame to swing out from the hinge bar. In a preferred embodiment the mullions include a planar forward surface having a hub extending outward therefrom to define oppositely extending channels. These channels accommodate flat panels or in the case of the end mullions accommodate the side flashing members in interlocking relationship. The operator is preferably a rack and pinion with the rack arm thereof terminating in a pivotal connection with the rear portion of the mullion. The frame members are preferably made of extruded aluminum, extruded plastic or formed sheet metal.
