发明名称 Guard screen for a rain gutter having flanges for gripping the front lip of a gutter
摘要 A guard screen for a rain gutter for placement over the open end of a rain gutter for preventing the accumulation of debris in the gutter. The guard screen of the present invention includes a longitudinal screen body bordered by a pair of longitudinal edges. The guard screen includes a first edge and a second edge. The first edge has a U-shaped channel defined therein for connection with the front lip of a conventional gutter. At the terminal ends of the arms of the "U" are provided opposing flanges that reduce the open end of the channel to a narrow slot. The lip of the gutter is gripped between the opposing flanges when the guard screen is in place and, when in position, the lip of the gutter is firmly held therein. The second edge includes a flange for placement between the shingles of a roof and the roof boards. The screen body is preferably composed of a polymerized material.
