Abstract: A deck board system for integrating artificial turf and drainage features includes a plurality of deck board panels, each with an extruded or pultruded panel body featuring an internal screw boss, an internal reinforcement strip, an overhang, a ledge, drainage openings on the topside, and underside openings. The system further comprises a finishing feature and an artificial turf layer. The overhang engages with adjacent panels, while the finishing feature straddles at least two panels and engages with the overhang. The artificial turf layer covers one or more deck board panels, providing a seamless and functional deck surface with integrated drainage capabilities.

Abstract: A screen door made of foamed polymer with heat welded joins between rails and stiles and a flat spline groove. The rails and stiles are extruded with the flat spline groove. Prior to joining the rails and stiles, a thin notch is made to remove the smooth skin of the extruded stiles before being joined to the cut ends of the rails. The heat welded joint between the notched stile and cut end of the rail is ten times stronger than conventional polymer door joints. A flat spline is used to insert the marginal portion of the screen into the flat spline groove, which is wider in the interior than at its entrance and resists the pull from normal forces on the screen much more effectively than a round spline in a rectangular groove.

Abstract: A screen door made of foamed, closed-cell, solid-core polyvinyl chloride includes two rails and two stiles connected together to form a rectangular frame having an opening. A groove is milled into the frame around the opening. The screen that is to cover the opening is fastened to the frame by pressing it with a spline into the groove. The rails and stiles are connected using dowels in addition to adhesives, or, alternatively, using screws and traditional mortise and tenon joints. Holes are drilled into the stiles and then screws are driven into the rails from within the holes. The holes are then filled with foamed plastic plugs over the screws. The screen door can be cut and trimmed at the job site to fit it to the particular door frame, removing up to about an inch from each edge.
