Claim 1
Independent Claim
356 words
An interlocking panel assembly comprising, in combination: a first panel member including a first base section and a first male flange section, said first flange section comprising: a first surface connected to and extending upwardly from a first connecting edge of said first base section and being substantially normal to said first base section; a second surface connected to said first surface and extending back away from said first connecting edge; a third substantially planar surface connected to said second surface whose plane forms an acute angle with said first base section; a fourth substantially planar surface substantially parallel to said first base section connected to said third surface and extending back towards and beyond the plane of said first surface, and a fifth surface connected to and extending downwardly from said fourth surface whose plane forms an obtuse angle with said first base section, said fifth surface being shorter than said third surface; a second panel member including a second base section which is substantially co-planar with said first base section and a second female flange section, said second flange section comprising: a sixth surface connected to and extending upwardly from a second connecting edge of said second base section and being substantially normal to said second base section; a seventh surface connected to said sixth surface and extending back away from said second connecting edge; an eighth substantially planar surface connected to said seventh surface whose plane forms an acute angle with said second base section; a ninth substantially planar surface substantially parallel to said second base surface connected to said eighth surface and extending back towards and beyond the plane of said sixth surface, and a tenth substantially planar surface connected to and extending downwardly from said ninth surface whose plane forms an obtuse angle with said second base section, said tenth surface being shorter than said eighth surface; said first and second flange sections being interlocked such that said first and sixth surfaces are adjacent to and coextensive with each other and said second, third, fourth, fifth, seventh, eighth, ninth and tenth surfaces form an interlocking assembly having a substantially trapezoidal crosssection.
Claim 2
Dependent Claim
356 words
An interlocking panel assembly comprising, in combination: a first panel member including a first base section and a first male flange section, said first flange section comprising: a first surface connected to and extending upwardly from a first connecting edge of said first base section and being substantially normal to said first base section; a second surface connected to said first surface and extending back away from said first connecting edge; a third substantially planar surface connected to said second surface whose plane forms an acute angle with said first base section; a fourth substantially planar surface substantially parallel to said first base section connected to said third surface and extending back towards and beyond the plane of said first surface, and a fifth surface connected to and extending downwardly from said fourth surface whose plane forms an obtuse angle with said first base section, said fifth surface being shorter than said third surface; a second panel member including a second base section which is substantially co-planar with said first base section and a second female flange section, said second flange section comprising: a sixth surface connected to and extending upwardly from a second connecting edge of said second base section and being substantially normal to said second base section; a seventh surface connected to said sixth surface and extending back away from said second connecting edge; an eighth substantially planar surface connected to said seventh surface whose plane forms an acute angle with said second base section; a ninth substantially planar surface substantially parallel to said second base surface connected to said eighth surface and extending back towards and beyond the plane of said sixth surface, and a tenth substantially planar surface connected to and extending downwardly from said ninth surface whose plane forms an obtuse angle with said second base section, said tenth surface being shorter than said eighth surface; said first and second flange sections being interlocked such that said first and sixth surfaces are adjacent to and coextensive with each other and said second, third, fourth, fifth, seventh, eighth, ninth and tenth surfaces form an interlocking assembly having a substantially trapezoidal crosssection.
Claim 3
Dependent Claim
