Abstract
The leaf guard for gutters is an elongated sheet of enamel coated aluminum adapted to fit over the rain gutter on a house in a manner that directs water flow from the roof into the gutter while preventing leaves and other debris from entering the gutter. In a first embodiment, the guard is formed into a planar section that is secured to a roof, a curved nose section extending from the planar section, a trough under the curved section and a cornered lip extending from the trough to secure the device to the outer rim of a gutter. In a second embodiment, the guard is formed into a planar section, an inwardly bent connection section that is connected to the inner rim of a gutter, and a curved nose section that hangs over the outer rim of the gutter. The guard also has rows of elongated slits in the planar section that permit some water to drip through to prevent bees and other insects from nesting beneath the device. The device is bendable such that the slope of the planar section can be changed to meet the varying needs.
