ABSTRACT:
A retention and tensioning frame assembly is used to securely and tautly mount a flexible sign, such as an advertisement display panel, to the side of a truck or of the semi-trailer of a tractor trailer. The frame assembly can be used to secure any flexible sheet-like panel to a flat surface, e.g. a billboard. The frame assembly comprises a series of frame sections which define a slightly open longitudinal cylinder adapted to receive therein a peripheral bead of the sign. The frame sections are adapted to be fixedly mounted to a side wall of the semi-trailer or the like thereby securing the sign to the side wall. Each frame section defines at an outer edge thereof opposite its cylinder an inturned lip which can be engaged by a pulling device for outwardly pulling on the sign, one side at a time, for tautly tensioning the sign. The frame sections, once engaged to the sign, are normally loosely attached to the side wall, and then the sign is tensioned using the pulling device before the frame sections are tightly secured to the side wall with the sign being taut.
