Anchor for a threaded fastener

An anchor for mounting a threaded fastener component to a generally round hole in a supporting panel structure, said anchor comprising:

• a generally planar main portion configured to extend beyond said hole to overlie a perimeter area around said hole, said main portion carrying said threaded fastener component;
• a series of flat strips each having one leg fixedly attached at one end to a rear side of said main portion, arranged to extend generally parallel to said rear side of said main portion projecting on edge with respect to said rear side, said strips each having an opposite leg free at one end projecting radially outward to normally lie across the perimeter of said hole, each of said strip free ends having a sloping tip edge adapted to engage an edge of said hole to be cammed radially inward as said anchor is pushed into said hole, said strips being configured to be able to be resiliently deflected radially inward to pass by said hole perimeter and into said hole, said strip tips also each having a notch which can accommodate the thickness of said panel structure to allow said strips to move radially back outward over a backside of said supporting structure past said hole to capture said supporting panel structure hole perimeter between said overlying portions of said main portion and an underside of said strip tip ends notched-out portion as said anchor is moved fully into said hole with said main portion abutting a front side of said supporting panel structure;
• and,
• a series of restraining features each fixed to said main portion and associated with a respective strip so as to restrain movement of said associated strip away from said rear side of said anchor main portion.
