Abstract
An anchoring plug made from a hard-elastic plastic material having a closed shank part 1 and two mutually opposite spreading fingers 2 and 3. A screw hole 10, extends through the shank part 1 down into a central space 12 between the spreading fingers for receipt of a screw 18. To be able to drive the plug directly into gypsum board without having to first drill a hole, one spreading finger 2 is longer than the other spreading finger and has a hook-shaped tip 4 forming a recess 5 at its free end. Initially the end of the shorter spreading finger 3 nests in this recess to provide a pointed end to the plug, but springs free of the recess when a screw is screwed into the plug.
Claims6
An anchoring plug of a hard elastic plastic material for fastening objects to bearer elements comprising a shank portion having a central opening extending therethrough, a pair of downwardly extending spreading fingers located on opposite sides of the center line of the opening and connected at their upper ends to said shank portion, one spreading finger being longer than the other spreading finger and having a hook-shaped, pointed tip at its free end opposite from said shank portion, said tip having an upwardly extending nose forming a recess therein, the free end of said shorter finger nesting in said recess and being held therein by said nose, whereby, after insertion of the plug into an element, insertion of a spreading member through the opening in the shank portion of the plug forces the shorter finger past the nose and out of said recess in the longer finger and spreads the fingers apart to grip the element.
