ABSTRACT:
The upper edge of an awning slat that is suspended obliquely in position is bifurcated into a channel-like structure running along the edge, having inwardly projecting beads on the free edges of the channel. For suspension of the slat, at various places along its length, the beaded channel is forced to spread and snap into notches behind twin barbs of a bracket. Each bracket has parallel ridges bending out from a base to meet the bifurcated grasping webs of the awning slat, the ridges of the bracket being barbed, so as to provide an oblique surface to spread the connecting webs of the awning edge apart until their beads snap into grooves between the barbs and the bracket base. The awning slat with its bifurcated edge is integrally made by extrusion of aluminum alloy and the brackets are relatively short pieces of aluminum alloy extrusions.
