Mobile home skirting system

Claim 1

In an elevated building having a space therebeneath, a skirt for said space comprising: a plurality of upright, corrugated ground supported panels disposed in edge-to-edge substantially coplanar relationship, each panel presenting a first and a second side and planar panel portions, at least certain of the planar panel portions of each of said panels being substantially coplanar with each other, upper retaining means attached to said building and adapted to receive said panels therein; interlock structure on adjacent vertical margins of said panels for maintaining the coplanar relationship therebetween, said interlock structure including a retaining corrugation wall, an overlap wall and a first reverse bend wall defining a vertical margin of one panel, said corrugation wall and overlap wall being obliquely oriented relative to the planar panel portions of the one panel and converging towards each other to cooperatively define therebetween a concave region, said reverse bend wall remote from said corrugation wall towards the corrugation wall and lying within said concave region, said reverse bend wall and and said extension wall presenting a first U-shaped interlock, an extension wall and a second reverse bend wall defining a vertical margin of another of said panels interconnected with said one panel, said extension wall and second reverse bend wall being obliquely oriented relative to the planar panel portions of said other panel and lying within said concave region, said second reverse bend wall extending from the edge of said extension wall remote from the planar panel portions of the other panel and towards the latter to present a second U-shaped interlock, said first and second U-shaped interlocks being interfitted within said concave region with said first and second reverse bend walls being substantially parallel, the smallest angle between said extension wall and said corrugation wall being greater than the angle between the corrugation wall and a plane normal to said planar panel portions whereby movement of said second U-shaped interlock in a direction toward said one panel is inhibited by said corrugation wall on the one panel.
