Abstract: A collapsible awning support frame includes an elongated, horizontal thrust bar fastenable by a lower mounting bracket to the vertical wall of a structure and extending outwards therefrom, and an elongated tension bar pivotably fastened to the thrust bar near the outer, free end of the thrust bar and extending upwards and backwards towards an upper mounting bracket. The upper mounting bracket, intended for fastening to the wall of the structure above and in vertical alignment with the thrust bar mounting bracket, has a hook pin extending upward and outward from the base of the bracket, for pivotably engaging a hole in the bottom wall of the tension bar, near the upper end of the tension bar. Upward movement of the tension bar is restricted by contact with a tab that extends downward from a roof section of the bracket which extends outward from the structure wall.
