ABSTRACT:
An elongated frame member and a rectangular screen frame assembly including the frame member having a unique cross sectional shape of the frame member for the reception and retention of flexible fiberglass or other types of screening material without requiring a separate spline or locking strip component. The uniform frame member cross section includes a substantially box or rectangular shaped main portion and substantially U-shaped portion positioned adjacent said main portion, said U-shaped portion including spaced apart first and second side walls and a bottom wall therebetween. Each first side wall is preferably substantially common with or defined by one surface of said main portion. A first plurality of spaced apart resilient barbs each extend laterally in cantilevered fashion from the first side wall toward, but not to, the second side wall, while a second plurality of spaced apart resilient barbs each extend laterally in cantilevered fashion from the second side wall toward, but not to, the first side wall. The first and second plurality of barbs overlap each other in staggered fashion whereby a distal edge of each of the first and second plurality of barbs collectively define a serpentine or zigzag shaped screen retaining passage therebetween. These barbs are sufficiently resilient to be forcefully deflected to enlarge the width of, and somewhat straighten, the passage while the edge portion of the screen panel is inserted therein. The barbs resiliently return to a substantially at-rest position when released to lockingly engage and retain the screen edge portion in said passage while also tensioning the screen panel by drawing more of the margin into said passage.
