Abstract
A high strength window screen frame that includes an extruded metal frame that fits within a window opening in a building. The frame is made up of a plurality of window frame units, each defining an opening and covered with mesh. A standoff leg portion of the window frame units provides a standoff separation of the mesh from a glass pane so that when objects strike the mesh and deflect the mesh, the glass pane is not impacted.
Claims12
A window screen comprising:
- a rectangular frame having a generally L-shaped cross-section, defining a standoff leg portion and a fascia portion extending perpendicular to the standoff leg portion, the fascia portion having an outside surface and an inside surface defining an opening, the fascia portion having a front face and a rear face;
- a mesh secured to the rear face of the fascia portion;
- wherein said standoff leg portion extends rearward from said rear face of said fascia portion a dimension that is greater than a dimension of said fascia portion from said outside surface to said inside surface;
- wherein:
- said window screen is comprised of more than one of said rectangular frames, with an upper one of said frames having a lower edge that abuts an upper edge of a lower one of said frames, each of said upper and lower edges having one of the fascia portions and one of said standoff leg portions, with said standoff leg portions of said upper and lower edges being adjacent one another;
- said standoff leg portions at said upper and lower edges having rear faces that are flush with one another;
- and
- a cap snaps over said rear faces of said standoff leg portions to secure said upper and lower frames together.

A window screen comprising:
- upper and lower frame units, each frame unit being made of four frame members secured together in a rectangular configuration;
- each frame member being generally L-shaped in cross-section, and having fascia portions and standoff leg portions perpendicular to each other, with an inside surface of the fascia portions defining an opening;
- a mesh secured to a back surface of the fascia portions of each of the frame units;
- and wherein
- the frame member on a lower edge of said upper unit abuts and is fastened to the frame member on an upper edge of said lower unit.

- a mesh secured to a back surface of the fascia portions of each of the frame units;
- and wherein
- the frame member on a lower edge of said upper unit abuts and is fastened to the frame member on an upper edge of said lower unit;
- wherein
- said window screen is comprised of more than one of said frame units, with an upper one of said frame units having a lower edge that abuts an upper edge of a lower one of said frame units, each of said upper and lower edges having one of said fascia portions and one of the standoff leg portions, with said standoff leg portions of said upper and lower edges being adjacent one another;
- said standoff leg portions of said upper and lower edges have rear faces that are flush with one another;
- and
- a cap snaps over said rear faces of said standoff leg portions of said upper and lower edges to secure said upper and lower frame units together.

A building window assembly comprising in combination:
- a window frame;
- a pane of glass mounted in said window frame;
- a window screen mounted in said window frame forward of said pane of glass, said window screen comprising:
- upper and lower frame units, each frame unit being made of four frame members secured together in a rectangular configuration;
- each frame member being generally L-shaped in cross-section, and having fascia portions and standoff leg portions perpendicular to each other, with an inside surface of the fascia portions defining an opening;
- wherein a rear face of the standoff leg portion of said frame member on an upper edge of said lower frame unit and a rear face of the standoff leg portion of said frame member on a lower edge of said upper frame unit are spaced forward of said pane of glass;
- a mesh secured to a back surface of the fascia portions of each of the frame units;
- and wherein
- the frame member on said lower edge of said upper frame unit abuts and is fastened to the frame member on said upper edge of said lower frame unit.
