Embodiments of the present disclosure include deflector support means for supporting the underside of a rain gutter deflector, said deflector support means including fastening means for retainably positioning said deflector support means with respect to the gutter with which said deflector means is to be associated characterized by being formed from strips of rigid material, having a straight, downward-sloping upper section and an adjacent downward curved portion for supporting the underside of such a deflector, and a lower downward directed segment adapted for affixation to the top front lip of an associated gutter either directly or via an intermediate gutter support ferrule.

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.

This invention relates to rain gutter devices, and in one embodiment comprises a bracket for use in supporting a rain-water deflector. The bracket is in the form of a flat continuum having a straight upper section and a double-reverse lower section. The lowermost portion includes a tab adapted for receiving the top edge of an associated rain-gutter. The upper section includes tabs for insertion into corresponding apertures in associated rain-water deflectors. Other embodiments include such brackets in combination with rain-water deflectors having bracket tab apertures, each of which consists of a central opening and side-openings that are separated from their associated central opening by a narrow web. Thereby, upon movement of the rain-water shield in its long dimension as a result of thermal expansion and contraction, the associated bracket tabs will break through the webs, eliminating restraint on migration of the shields and avoiding buckling of the rain-water shield.
