Claim Text:
1. A curtain apparatus comprising: a first elongated member disposed generally along a first horizontal axis for rotation about the first horizontal axis; a first curtain having a top, bottom, first end and second end, the top of the first curtain being adapted to be attached to a frame disposed above the first elongated member; the first elongated member being suspended from the frame by the first curtain whereby the first elongated member moves up when rotated in the first rotary direction as the first curtain is rolled onto the first elongated member and the first elongated member moves down when rotated in the second rotary direction and the first curtain is being unrolled from the first elongated member; a second elongated member disposed generally along a second horizontal axis for rotation about the second horizontal axis; a second curtain having a top, bottom, first end and second end, the top of the second curtain being adapted to be attached to the frame disposed above the second elongated member; the second elongated member being suspended from the frame by the second curtain whereby the second elongated member moves up when rotated in the first rotary direction as the second curtain is rolled onto the second elongated member and the second elongated member moves down when rotated in the second rotary direction and the second curtain is being unrolled from the second elongated member; a third elongated member disposed generally along a third horizontal axis for rotation about the third horizontal axis; a third curtain having a top, bottom, first end and second end, the top of the third curtain being adapted to be attached to the frame disposed above the third elongated member; the third elongated member being suspended from the frame by the third curtain whereby the third elongated member moves up when rotated in the first rotary direction as the third curtain is rolled onto the third elongated member and the third elongated member moves down when rotated in the second rotary direction and the third curtain is being unrolled from the third elongated member; a fourth elongated member disposed generally along a fourth horizontal axis for rotation about the fourth horizontal axis; a fourth curtain having a top, bottom, first end and second end, the top of the fourth curtain being adapted to be attached to the frame disposed above the fourth elongated member; the fourth elongated member being suspended from the frame by the fourth curtain whereby the fourth elongated member moves up when rotated in the first rotary direction as the fourth curtain is rolled onto the fourth elongated member and the fourth elongated member moves down when rotated in the second rotary direction and the fourth curtain is being unrolled from the fourth elongated member; a left gear operatively attached to a left end of the first elongated member; a right gear operatively attached to a right end of the first elongated member; a left gear operatively attached to a left end of the second elongated member; a right gear operatively attached to a right end of the second elongated member; a left gear operatively attached to a left end of the third elongated member; a right gear operatively attached to a right end of the third elongated member; a left gear operatively attached to a left end of the fourth elongated member; a right gear operatively attached to a right end of the fourth elongated member; the left gear of the first elongated member being operatively engaged with the right gear of the second elongated member; the left gear of the second elongated member being operatively engaged with the right gear of the third elongated member; the left gear of the third elongated member being operatively engaged with the right gear of the fourth elongated member; and the left gear of the fourth elongated member being operatively engaged with the right gear of the first elongated member whereby rotation of any one of the first, second, third or fourth gears causes all of the other gears and elongated members to rotate.
