  • Patent number: 5802777
    Abstract: A protection cover for an eaves gutter capable of permitting snow lumps, fallen leaves, pebbles, sand, dust and the like dropping from an eaves edge of a roof to smoothly slip off the protection cover to drop onto the ground under the eaves and thus preventing them from entering the eaves gutter. The protection cover includes a net cover body fitted on an upper opening of the eaves gutter. The net cover body is formed so as to have a central portion upwardly arcuately expanded and both lateral portions laterally arcuately expanded while being downwardly inclined from the central portion. The protection cover also includes a pair of fixing frames for tightly fixing opposite lateral edges of the net cover body to respective lateral upper edges of the eaves gutter.
