Anchoring retainer for threaded fasteners

摘要

An anchoring retainer is provided for mounting at one side of a supporting structure such as a wall or ceiling having a through or restrictive opening therein through which the retainer is first inserted to reach one side of the structure or for mounting in a blind hole in a concrete floor or wall. Generally the same retainer may be used with a through opening or blind hole. The retainer, adapted to be used with a threaded element, comprises a flexible unitary one-piece body made from a plastic material. The body has an axis, is of generally triangular configuration and has at the apex thereof a sleeve provided with an opening surrounding the axis through which the threaded element extends. The sleeve has a pair of integrally formed outwardly diverging elongated flexible legs. An elongated flexible strut of V-shape is spaced axially from the sleeve and includes a central strut portion located beneath and spaced from the sleeve along with a pair of outwardly diverging strut portions which are integrally connected to the central strut portion and to the flexible legs near the outer ends thereof.
