  • Patent number: 11192222
    Abstract: A wedge anchor driver for driving an anchor having a bolt into a surface such that a portion of the bolt is exposed, the wedge anchor driver having a flute extending between a top end and a shaft, the flute housing a plurality of cavities having a first cavity configured to fit onto a first nut, the first cavity having a first socket size; a second cavity configured to fit onto a second nut, the second cavity having a second socket size smaller than the first socket size; and a third cavity configured to receive the portion of the bolt; wherein the anchor driver shaft is lockable into a hammer drill, such that a user can drive the anchor into a corresponding hole with the hammer drill in a hammer mode, and then tighten the first nut or the second nut by switching the hammer to a drill mode.

  • Patent number: 10323671
    Abstract: A method for installing an anchor having: making a hole into the material in which the anchor is to be installed, by using a hammer drill; after associating an anchor driver with the chuck of the hammer drill, using the so created anchor driver-hammer drill first assembly, with the hammer drill in hammer mode, to hammer the anchor into the hole; and, after switching the hammer drill to drill mode, tightening the nut or bolt of the anchor using the anchor driver-hammer drill first assembly, or a second assembly comprising the hammer drill and a socket.

  • Patent number: 9592592
    Abstract: A wedge anchor driver comprising: a first member having a first opening configured to fit onto the nut of a wedge anchor and a second opening configured to receive a predetermined length of the outer end of the wedge anchor's bolt; and a second member associated with the first member, wherein the second member's distal end is configured to fit, and be lockable, into the chuck of a hammer drill, such that, after the wedge anchor driver is locked into the chuck of the hammer drill, a user can drive the wedge anchor into a corresponding hole with the hammer drill in hammer mode and then tighten the nut of the wedge anchor by switching the hammer drill from hammer mode to drill mode.
