  • Patent number: 5664595
    Abstract: A stiff supportive covering with an attached net-like material that forms a tent-like enclosure for protection from flying insects when the stiff supportive covering is positioned atop a conventional umbrella in an open position and the net-like material is extended to the ground. The stiff supportive covering is preferably a circular-shaped plastic material and defines a relatively small circular opening permitting passage therethrough of the uppermost end of the conventional portable umbrella's supporting pole. The net-like material is attached about the circumference of the covering and has a length sufficient to extend to the ground. The net-like material has a plurality of weights attached at a lower edge thereby to retain the net-like material in contact with the ground.
