Windshield shading curtain device

A windshield shading curtain device for shading a driver of a vehicle from sunlight thereby enhancing visibility for the driver, said device comprising:

• a vehicle having a cab and a windshield, said vehicle including a curtain rail being disposed within said cab and extending along a full width of said windshield, said curtain rail including a top wall and a front wall and a back wall each extending downwardly from said top wall, said front wall and said back wall being oriented parallel to each other such that said curtain rail has a U-shape, said front wall having a bottom edge and a bend being spaced from and being coextensive with said bottom edge such that said bottom edge is directed toward said back wall, said back wall having a bottom edge and a bend being spaced from and being coextensive with said bottom edge of said back wall such that said bottom edge of said back wall is directed toward said front wall;
• wherein an opening is defined between said bottom edge of said front wall of said curtain rail and said bottom edge of said back wall of said curtain rail;
• wherein said top wall of said curtain rail is attached to a ceiling of said cab such that said opening defined in said curtain rail faces downwardly, said curtain rail being aligned with an upper edge of said windshield, said curtain rail being spaced from and being oriented parallel to said upper edge of said windshield;
• a curtain being slidably attached to said curtain rail thereby enabling said curtain to hang in front of said windshield of said vehicle, said curtain being comprised of a translucent material wherein said curtain is configured to pass light through said curtain thereby enabling a driver to see through said curtain, said curtain being comprised of an ultraviolet light blocking material wherein said curtain is configured to inhibit ultraviolet light from passing through said curtain thereby enabling the driver to be protected from ultraviolet light which passes through said windshield, said curtain having a polarizing layer being applied to said curtain, said polarizing layer being comprised of a light polarizing material wherein said polarizing layer is configured to polarize the light passing through said polarizing layer thereby protecting the driver's vision from glare produced by headlights of oncoming vehicles or other sources of light, said curtain having a length being sufficient to extend across a partial width of said windshield wherein said curtain is configured to enable to driver to be shaded from ultraviolet light which passes through a portion of said windshield, said curtain being comprised of a deformable material thereby enabling said windshield to be collapsed to extend across a reduced width of said windshield wherein said curtain is configured to enable to driver to position said curtain at a selected point along said windshield;
• a mounting member having a rear side being bonded to a back surface of said curtain, said mounting member being aligned with a top edge of said curtain, said mounting member being elongated to extend along a full width of said top edge of said curtain;
• a plurality of couplers, each of said plurality of couplers including a stem being coupled to and extending upwardly from a top side of said mounting member, said stem of each of said plurality of couplers being evenly spaced apart from each other and being distributed along a full length of said top side of said mounting member, each of said plurality of couplers including a head having a lower surface being attached to a top end of said stem, said head associated with each of said plurality of couplers having a top surface and an outer surface extending between said top surface and said lower surface, said outer surface of said head associated with each of said plurality of couplers having a depression extending around a full circumference of said outer surface, said depression in said outer surface of said head associated with each of said plurality of couplers having a bounding surface which has a lower side sloping upwardly to intersect a middle side and an upper side curving upwardly from an intersection with said middle side, said depression in said outer surface of said head associated with each of said plurality of couplers receiving said bottom edge of said front wall of said curtain rail and said bottom edge of said back wall of said curtain rail thereby enabling said head associated with each of said plurality of couplers to be slidably engaged to said curtain rail having said head associated with each of said plurality of couplers being positioned in said opening defined in said curtain rail, said head associated with each of said plurality of couplers being slidable along a full length of said curtain rail for either collapsing said curtain to extend across a reduced width of said windshield or extending said curtain along a greater width of said windshield.
