Abstract: A free-standing window screen fabrication system for releasably mounting a screen fabric or other pliable sheet material on a free-standing screen frame in such a manner as to self-tighten the fabric or material during installation. A screen is disposed and held securely in place between a screen frame extrusion member and a trim mold. The screen frame extrusion defines a mounting surface disposed below and parallel to an exterior face. The screen frame extrusion further defines an interior channel for receiving one end of a connector, a plurality of screen frame extrusions being secured in an end-to-end fashion to define a free-standing screen frame. A mounting rib extends along the mounting surface and terminates below the exterior face in the preferred embodiment. A bead is defined at the terminal edge of the mounting rib to serve as a locking mechanism. The trim mold defines a channel opening on the bottom surface thereof to closely receive the mounting rib of the screen frame extrusion.

Abstract: A window screen installation system for releasably mounting a screen fabric or other pliable sheet material in such a manner as to self-tighten the fabric or material during installation. Moreover, the screen frame and trim mold are designed to allow for the mounting of the fabric or material without damaging the same such that it may be removed and reused as required. A screen is disposed and held securely in place between a screen frame extrusion member and a trim mold. The screen frame extrusion defines a mounting surface disposed below and parallel to an exterior face. A mounting rib extends along the mounting surface and terminates below the exterior face in the preferred embodiment. A bead is defined at the terminal edge of the mounting rib to serve as a locking mechanism. The trim mold defines a channel opening on the bottom surface thereof to closely receive the mounting rib of the screen frame extrusion.
