Abstract
Abstract Disclosed is a nailless anchoring mechanism for the roofing or siding panels which includes anchor plates molded into each panel and corresponding retaining brackets. Knurled retaining rods are used to anchor the panel to roof trusses or wall studs by forcing the knurled rod ends through opposing star fastener openings in the panel anchor plates and the retaining brackets when the retaining brackets are secured behind a structural member.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
149 words
A mechanism for anchoring a pre-fabricated panel to structural members such as roof trusses or wall studs comprising an elongated knurled retaining rod projecting from the underside of said prefabricated panel, and a retaining bracket having a first end portion sized to fit over and secure to a panel supporting structural member, a second end portion having an extension wall extending from one side of said first end portion, and a base plate secured to said extension wall having a star fastener opening therein whereby said retaining bracket base plate can be lockingly forced onto the end of said knurled retaining rod to lockingly engage said retaining bracket and thereby said panel to said structural member, said side wall extension having a flexure portion to permit flexing of said second end portion in the plane of said extension wall to provide a spring restoring force against said knurled rod.
