Abstract
An insect screen that includes a rigid frame defining a frame perimeter and a metal screen located within the rigid frame perimeter. The metal screen has a plurality of metal elements with a dark mat surface. The metal elements have a width of about 0.001 inch to about 0.0015 inch. The insect screen has a reduced visibility such that it appears nearly invisible or transparent.
Description




BACKGROUND OF THE INVENTION




The invention generally relates to insect screens for fenestration units such as, for example, window screens, that are less visible.




A wide variety of window screens are available in the prior art. For many years, most window screens were made of metal, which would eventually rust. Additionally, the individual strands or elements of such screens were relatively wide leading to significant attenuation and distortion of light passing there through. These characteristics were undesirable in that they distorted the view available through windows or doors treated with such material.




SUMMARY OF THE INVENTION




In accordance with the present invention, there is provided an insect screen that includes a rigid frame defining a frame perimeter and a metal screen located within the rigid frame perimeter. The metal screen has a plurality of metal elements having a width from about 0.001 inch to about 0.0015 inch and a dark mat surface, which reduces the visibility of the screen.




Also in accordance with the present invention, there is provided a method that includes providing an insect screen having a rigid frame defining a frame perimeter and a metal screen located within the rigid frame perimeter. The metal screen has a plurality of metal elements that have a width of about 0.001 inch to about 0.0015 inch and a dark mat surface, which reduces the visibility of the screen. The method further includes providing a fenestration unit and placing the insect screen in the fenestration unit.

DETAILED DESCRIPTION





FIG. 1

is a fragmentary drawing of a portion of an insect screen


10


in accordance with the present invention. The insect screen


10


consists of a rigid frame


20


defining a rigid frame perimeter


40


. A metal screen


30


is located within the rigid frame perimeter


40


. The rigid frame


20


supports the metal screen


30


on all sides of the metal screen


30


at the rigid frame perimeter


40


.





FIG. 3

is a prospective view of the insect screen shown in

FIG. 1

located in a fenestration unit


120


. The rigid frame


20


may include two pairs of opposed rigid frame members. A first pair of opposed rigid frame members


50


can be oriented along a horizontal rigid frame axis. A second pair of opposed rigid frame members


60


can be oriented along a vertical rigid frame axis. The four rigid frame members


50


,


60


can generally form a square or rectangle shape. However, the rigid frame may be any shape.





FIG. 2

is a fragmentary view of a portion of the insect screen shown in FIG.


1


. The metal screen


30


includes a plurality of metal elements


70


. The metal elements


70


may have a width or diameter W of about 0.001 inch to about 0.0015 inch, or about 0.0012 inch. Each metal element


70


has a length to span the distance between opposed rigid frame members


50


,


60


. Each metal element


70


may be connected to the opposed rigid frame members


50


,


60


in any conventional manner.




The plurality of metal elements


70


can include a plurality of horizontal metal elements


80


and a plurality of vertical elements


90


. The horizontal metal elements


80


may be spaced apart from each other a distance Dv of about 0.015 inch to about 0.020 inch or about 0.018 inch. The vertical metal elements


90


may also be spaced apart from each other a distance DH of about 0.015 inch to about 0.020 inch or 0.018 inch.




The plurality of horizontal and vertical metal elements


80


,


90


can be constructed and arranged to form a mesh where a horizontal metal element intersects a vertical metal element perpendicularly. The intersecting horizontal and vertical metal elements


80


,


90


may be woven together. Alternatively, the intersecting horizontal and vertical metal elements


80


,


90


may be fused together.




The metal screen


30


may be formed from a metal that has a low coefficient of thermal expansion such as, for example, stainless steel. A low coefficient of thermal expansion reduces thermal expansion or contraction due to temperature changes and thus reduces distortion of the metal elements


70


and aids in reducing the visibility of the insect screen


10


. The metal screen


30


may be formed from a metal that has a high tensile strength, such as, for example, stainless steel, to reduce breaks in the metal screen


30


.




The surface


100


of the metal elements


70


is a dark non-reflective, dull or mat finish disposed thereon. A dark non-reflective, dull or mat finish is defined herein to mean a finish that absorbs a sufficient amount of light such that the metal screen


30


appears less obtrusive than a metal screen


30


without such finish. The dark non-reflective or mat finish may be any color that absorbs a substantial amount of light, such as, for example, a black color. The dark non-reflective or mat finish can be applied to the metal element surface


100


by any means available such as, for example, anodizing, liquid coating, ion deposition, plasma deposition, vapor deposition, and the like. Liquid coating may be, for example, paint, ink, and the like.




The insect screen


10


can be used in conjunction with a fenestration unit


110


. The fenestration unit


110


may be any arrangement of components constructed and arranged to interact with an opening in a surface such as, for example, a building wall, roof, ceiling, floor, and the like. The surface may be an interior, exterior or interior and exterior surface. The fenestration unit


110


may be a window (i.e. an opening in a wall or building for admission of light and air that may be closed by casements or sashes containing transparent, translucent or opaque material and may be capable of being opened or closed), such as, for example, a picture window, a bay window, a double-hung window, a skylight, egress window, and the like. The fenestration unit


110


may be a doorway or door (i.e. a swinging or sliding barrier by which an entry may be closed and opened), such as, for example, a front door, a patio door, a French door, a side door, a back door, a storm door, a garage door, a sliding door, and the like.




The insect screen


10


may be placed in and form a part of the fenestration unit. The insect screen


10


may be permanently affixed to the fenestration components or the insect screen


10


may be able to be removed from the fenestration components. The insect screen


10


may be placed on the interior, exterior or both the interior and exterior surface of the fenestration unit


110


. The insect screen


30


may be placed within the fenestration unit


110


.
