ABSTRACT:
A durable sealing curtain assembly preferably comprising a pair of tracks slidably attached to opposite sides of an opening such as a door or window, a curtain having its lateral edges engaged by the tracks, and spring systems attached to each track, whereby the spring systems urge the tracks outwardly to maintain the curtain taut yet allow the tracks to slide inwardly towards the center of the opening so that the curtain does not endure excessive pressure upon application of an external force. At least one track preferably also comprises a cam mechanism that is operative to urge the track inwardly to release tension from the curtain and thereby allow the curtain to be more easily raised or lowered, after which, the cam mechanism can be disengaged to allow the track to return to its outwardly biased position, thus returning the curtain to a taut condition.
