ABSTRACT:
Disclosed is an air-flow-directing grille assembly of the type having two frame members and a grille bar supported by such frame members for pivoting movement about a grille bar axis. In the improvement, each frame member has a hole, the bar has an axle extending through the holes and each hole and the axle are cooperatively sized to provide a friction fit between such hole and axle. The grille bar is thereby frictionally retained in a position. A new method for making a grille assembly includes providing a pair of frame members, each having a hole therethrough of a first diameter. A grille bar is provided to have an axle with a second diameter at least equal to the first diameter. The axle and the frame member holes are urged into frictional engagement with one another and the grille bars will thereby hold a selected air-flow-directing position.
