Abstract:
1. A curtain assembly for covering an opening, comprising: a. an elongated curtain having a first end mounted at a first end of the opening, an opposing second end that is moveable between the first end of the opening and an opposing second end of the opening, and opposing lateral sides slidably attached to opposing sides of the opening; b. a track on each of the opposing sides of the opening, wherein each track has a securing member for securely engaging an edge of a lateral side of said curtain, wherein at least one track is slidably mounted to a side of the opening such that said slidably mounted track can slide toward the opening to decrease tension on said curtain or slide away from the opening to increase tension on said curtain; c. a connecting member fixedly attached to the side of the opening and extending through an elongated slot formed in said slidably mounted track, wherein said connecting member holds said slidably mounted track adjacent the side of the opening while allowing said slidably mounted track to slide toward the opening to decrease tension on said curtain or to slide away from the opening to increase tension on said curtain; and d. a spring assembly attached to said slidably mounted track, wherein said spring assembly comprises a spring that engages said connecting member to bias an end of said elongated slot in closest proximity to said opening toward said connecting member such that tension is increased on said curtain.
