  • Patent number: 4961981
    Abstract: A cover article that comprises a plurality of compartmentalized members connected together to form a geometric shape, a netting connected to the plurality of compartmentalized members and extending across the interior of the geometric shape, and a plurality of weighted elements contained within the interior area of each of the compartmentalized members. The compartmentalized members are made up of a tube of flexible material having closed ends. The closed ends are hinged to adjacent compartmentalized members. Each of the compartmentalized members are generally water-resistant. The netting has a cross-hatched configuration suitable for preventing insects from passing therethrough. The weighted elements are made up of high-density plastic debris or lead pellets having a buoyancy suitable for floating on water. The plastic debris fills less than two-thirds of the entire interior volume of each of the compartmentalized members.
