发明名称 Protective cover for gutters
摘要 A protective structure for a gutter includes an elongated, impervious sheet wide enough to extend across at least about 90% of the width of the gutter and up under a lower edge of roofing material. The outer edge of the cover curls downwardly and the water follows the curvature by surface tension to cascade into the gutter. The cover may be held in place by straps that extend transversely across it and have one end engaged under the inwardly turned lip of the gutter and the other end engaged under the roofing material. Alternatively, clips may connect the curl to the inwardly turned lip of the gutter. Flanges extending downwardly from the ends of the gutter block off openings there.
