Patent ID: 7765742

Claim:
A gutter cover for preventing debris from falling into the gutter and for directing water flow into the gutter, the gutter cover comprising: an elongate sheet having a longitudinal axis transverse to a water flow direction, the sheet including: a shingle mounting portion for reception between a roof shingle and roof; a covering portion adjacent the shingle mounting portion and sized to extend over the gutter; a surface tension curve downstream from the covering portion for directing water into the gutter, the curve having a varying slope so that surface tension causes the water to adhere to the curve and be directed into the gutter, said surface tension curve comprising an upper rearward opening concave curve defined by a first radius and a lower rearward opening concave curve defined by a second radius larger than the first radius; a lowermost edge disposed downstream from the surface tension curve; and a bend line separating the mounting portion from the covering portion, the bend line extending parallel to the longitudinal axis and including weakened metal to facilitate bending to an angle for conforming the mounting portion to the roof, wherein said first radius is in the range of ⅛ in. to ½ in.
