  • Patent number: 5522342
    Abstract: An apparatus for preventing flag banners from folding is provided. The apparatus comprises a flag pole having an upper portion with an annular recess formed therein, a lower base with an annular recess and two connecting buttons rotatably coupled within the respective annular recesses. The flag banner is connected to the flag pole by two button holes engaged by the two connecting buttons. The connecting buttons rotate within the annular recesses so that when the wind blows in a different direction, the flag banner can change direction accordingly, without wrapping the flag around the pole.
