Abstract:
An apparatus for screening off large surfaces, comprising:(a) at least one curtain (14) having a number of suspension lines (26) integrated into the curtain and freely mobile along the length of the curtain;(b) a number of support lines (12) for supporting the suspension lines such that the curtain is mobile for opening or closing of the curtain, wherein one or more of the suspension lines (26) is stretched to achieve a desired tension between two or more support lines (12); and,(c) one or more hooks (15) for connecting at least one suspension line to a support line (12), wherein each hook (15) has a notched shaped leg that is elastically bendable and shaped to have a first open position forming an open loop, into which the suspension line (26) can be inserted, and a second, closed position of the hook in which a single piece of the suspension line (26) can move freely along its length yet when two or more pieces of the suspension line are inserted, they are tightly affixed to the connector, thereby maintaining the desired tension.
