Free-standing window screen fabrication system

摘要

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. A plurality of retention barbs are formed in the channel to engage the mounting rib bead in order to prevent inadvertent removal of the trim mold from the mounting rib.
