  • Patent number: 8842256
    Abstract: Provided is an easily fabricated awning-member molded article having excellent strength, and an awning formed from a plurality of such awning-member molded articles. When an awning-member molded article is viewed from its bottom surface, a small-triangular plate portion bent toward a bottom surface of a second dihedron and a small-triangular plate portion bent toward a bottom surface of a third dihedron have a predetermined thickness at their portions abutted against each other, so that the second dihedron and the third dihedron in each basic element are coupled to each other. Further, a middle-triangular plate portion bent toward the bottom surface of the second basic element and a middle-triangular plate portion bent toward the bottom surface of the third basic element are provided with a predetermined thickness at their portions abutted against each other, so that the second basic element and the third basic element are coupled to each other.
