This mesh screen structure is made by the use of a plastics molding technique and comprises a plurality of latitudinal threads and a plurality of longitudinal threads molded together to give a shape or appearance similar in all aspects to a woven metal mesh.
Claims6
A molded plastic mesh screen covering for at least one sound emitting opening defined in an audio cabinet, said mesh screen structure comprising a plurality of equally spaced latitudinal threads extending generally perpendicular to a plurality of equally spaced longitudinal threads, said latitudinal and longitudinal threads being interwoven so as to intersect to be integrally interconnected together at each area of intersection to provide a unitary structure having a diameter measured from a mold parting line, said line defined as passing through said areas of intersection, to a diametrically opposite point on each of said respective threads in a direction facing outwardly from said cabinet, said diameter being substantially equal to the diameter of said threads.
A cabinet having at least one opening defined therein, which comprises a housing, a plastic mesh screen structure covering said opening, said screen structure comprising a plurality of equally spaced latitudinal threads and a plurality of equally spaced longitudinal threads extending generally perpendicular one to the other, said latitudinal and longitudinal threads being molded together at areas of intersection to be integrally interwoven, said screen structure defining a mold parting line at a location displaced a predetermined distance in a direction towards said cabinet from an imaginary plane which contains and passes through said areas of intersection of said threads, that is, from the center plane of the screen structure which lies in between the thickness of said screen structure, the diameter of which, defined as measured from said mold parting line to diametrically opposite points on each of said respective threads in both directions facing outwardly and inwardly of said cabinet, being substantially equal to the diameter of said threads.
