  • Publication number: 20090173462
    Abstract: A wind screen insert for framing members of screened enclosures such as pool cages and the like, the wind screen being adapted to pivot about a vertical or horizontal framing member to which it is hingedly attached. The wind screens which may be of various dimension are mounted within an opening defined by conventional posts/columns, purlins, beams, base and eve rails using at least one double acting spring hinge. The hinge allows the wind screen to pivot up to 90 degrees in either direction relative to its closed or “resting” position when a predetermined amount of force is applied to the wind screen. The hinge also automatically returns the wind screen to its original closed position when the force is diminished below the predetermined amount. The spring tension within the hinges is adjustable to permit screen movement at a desired amount of force applied to the wind screen which will be a function of the screen's surface area and wind speed.
