ABSTRACT:
Embodiments useful as means for inhibiting the accumulation of leaves and other debris in household rain gutters. Embodiments include structures which comprise a deflector having a sloped portion, the top edge region of which is adapted for juxtapositioning to the roof shingles, and the bottom edge region of which is arcuate through a large radius cross-section. In such embodiments, the farthest outward extension is outside the outermost edge of the associated rain gutter and the lower edge is positioned between the edges of the rain gutter. Embodiments include means for attenuating the force of water and reducing the localized concentrating of water flowing thereover, such as longitudinal ridges and/or means for improving the surface wettability. Through practice of this device, kinetic gravity-induced forces on up to normal volumes of water flowing down the sloped portion may be kept, through the arcuate portion, below the forces acting counter-directionally thereto due to surface tension of the water normally to prevent substantially centripetal ejection of water as its direction of travel is changed to deposit it in the gutter while ejecting water carried debris carried outside the gutter.
