Abstract The one-piece anchor is preferably fabricated of wire and comprises a base portion in the form of a planar spiral of spaced coils, and a shank portion formed by extending the center inner end of the spiral upwardly and generally perpendicular to the plane of the spiral. The base portion is adhesively secured to its support. The spaced coils of the base present a relatively large bonding surface with a sufficient open area to permit rapid dispersion and evaporation of the solvents of the adhesive, whereby the drying time of the adhesive to secure a good bond between the anchor and its supporting surface is greatly reduced when compared to the drying time of the prior art anchors. To reinforce and maintain the coils of the spiral in the planar position, the outer end portion of the spiral is extended upwardly and inwardly to extend across and contact the top of the coils. Further rigidity of the anchor is obtained by looping the outer end of the portion extending across the coils around the base of the shank.
A one-piece anchor having a base portion for receiving adhesive for securing the anchor to a rigid supporting surface and having a shank portion extending generally perpendicular to the base portion to receive a generally cantilever load, said base portion comprising a planar spiral having spaced coils terminating in an inner end and in a peripheral outer end, said shank portion comprising an extension of the inner end bent upwardly to extend from one face of the spiral, the outer end having an end portion which is bent upwardly and inwardly to extend across said one face and contact the top of the coils with the terminal end of the end portion being looped around the shank at a point adjacent the base, said coils being sufficiently spaced from each other to receive an application of adhesive to a major portion of their surfaces and to provide an open area to permit the dispersion and evaporation of the solvent material in the adhesive.
