Abstract

Panels for roofing or siding having flat sides and sides molded to be imitative of a plurality of shingles and underlying and overlying portions at the edges of the panels operable, when interengaged, to prevent lateral movement of the adjacent panels relative to each other and lifting of the overlying portions from the underlying portions, and said underlying portions being adapted to be secured by fastening elements to the surfaces to which the panels are applied.

Claims

1. A panel imitative of a plurality of shingles comprising a unitary structure having a uniformly flat bottom side and a top side molded to the pattern of a plurality of shingles and means at the edges of the panel for lockingly interengaging adjacent panels to each other, said interlocking means comprising along two intersecting edges portions at the inner side and along two other intersecting edges portions at the outer side, said portions extending lengthwise with each of Said edges and each portion being of lesser thickness than the panel and having outer and inner sides, the outer sides being coplanar with the outer sides of the panel and the inner sides being situated intermediate the inner and outer sides of the panels, the edge faces from which the portions project being perpendicular to the inner and outer sides of the panel and to the inner sides of the portion;

said inner portions having at their inner sides right triangular ribs extending from their inner sides in spaced parallel relation to said edge faces with their right sides parallel to said edge faces, said edge faces and said right sides defining grooves of rectangular cross-section, the apices of the ribs being of lesser height than the edge faces and the hypotenuse sides sloping from the apices toward the inner sides, and tongues at the ends of the inner portions of lesser thickness than the portions having outer and inner sides, the outer side being situated intermediate the outer and inner sides of the inner portions and the inner side being coplanar with the inner side of the inner portions; and

said outer portions containing grooves in their inner sides of right section situated in spaced parallel relation to the edge faces in which said ribs are engageable, the right sides of said grooves in conjunction with said edge faces defining rectangular ribs which mate with said rectangular grooves so that there are interengaged ribs and grooves, said outer portions inwardly of said right triangular grooves being of lesser thickness than the portions outwardly thereof such that the surfaces are spaced from the inner sides of the inner portions and define therebetween gaps of such size as to accommodate the heads of fastening elements driven through the inner portions and said edge faces containing channels of a thickness corresponding to the thickness of said tongues, said channels being located inwardly of said outer sides in positions to receive said tongues.
