Patent ID: 7011132

Claim:
An environmental strip curtain system for at least partially obstructing a passage through a wall, the system including a curtain-holding apparatus for suspending a plurality of flexible transparent strips of the curtain, each strip including a plurality of holes of a selected diameter located adjacent to an upper end of the strip, the curtain-holding apparatus comprising: a bar, and mounting means for mounting the bar to fixed structure adjacent to said passage; and a plurality of pegs coupled to the bar, each peg including a stalk extending outwardly from the bar, each stalk having a proximal end connected to the bar and a distal end including a cap spaced by a pre-selected distance from the proximal end of each stalk, each cap being generally symmetric with respect to the stalk to which the cap is fixed, an outermost edge of the cap being ovate to circular and sized greater than said selected diameter of the holes in each strip, a distal outer surface of the cap having a dome-shaped surface extending from a distal extremity of the cap to the outermost edge of the cap facilitating the stretching of said holes of each strip to a size sufficient to permit the strip to be forced over the outermost edge of the cap.
