  • Patent number: 6840254
    Abstract: An enclosure of fabric with four vertical sides that is open at the top and bottom. A continuous sheath is sewn around the top edges of three sides. Three rods are inserted into the sheath from one end. The rods are not held to each other except by the sheath. A support person stands in front of the blind and holds the first and third rods apart and parallel to each other. The rods hang three respective sides of the blind directly. The fourth side hangs from the tension span between the two ends of the rod sequence. The fourth side has a flap at the bottom. The support person stands on this flap with his or her back to the wind. This prevents billowing and raising of the blind by the wind. An occupant can enter this blind before or after it is raised by the support person.
