US Patent 9453524 Mechanically biased cantilever fastener assembly

A fastener assembly includes a body, a cup and a faceplate. The fastener assembly is a long thin shape for insertion into an opening in a substrate prior to actuation. Once inserted in the substrate, the fastener assembly may be actuated by the insertion of a bolt into a central aperture in the assembly and the tightening of the bolt against the cup. The actuation of the assembly causes the body of the assembly to fold at four points and to thereby secure the assembly to the substrate.
