  • Patent number: 4621940
    Abstract: The present application is concerned with an elongated stiff but bendable plastic article which finds particular utility in highway delineators. The article has a central lens shape in the cross-section perpendicular to its longitudinal axis which is formed by joining two sheets along both of their longitudinal edges. The sheets both have parallel longitudinal edges and are configured in an arc in their shorter dimension. A reverse radius is provided in each longitudinal edge just before it joins the similar edge of the other sheet to allow the article to bent 90.degree. across its longitudinal axis in the plane of the sheets' juncture without significant plastic deformation. The article is constructed of a thermoplastic that can sustain substantial elastic deformation.
