发明名称 COMPOSITE GUTTER GUARD
摘要 A composite gutter guard is adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and otter buildings. The gutter guard includes an elongate polymer guard panel definin g a plurality of spaced filter openings. The guard panel is adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter. A polymer-coated mesh layer overlies the guard panel in an area of the filt er openings and cooperates with the guard panel to capture and separate debris from rainwater runoff entering the gutter. A heat weld connects the mesh layer to the guard panel.
