| 20110038683 | After application anchor bolt - The present invention relates to an anchor bolt and more specifically pertains to a post-installed anchor that is securely anchored to, for example, an existing concrete floor. The post-installed anchor has a sleeve fit on a bolt body and a fixation member arranged on an edge of the bolt body and screwed to a threaded end of the bolt body. The fixation member has an internal threaded end and an expansion end. The expansion end is divided into four expansion pieces by slits. The expansion pieces are arranged to face a head of the bolt body and are slightly widened toward the head of the bolt body. One end of the sleeve forms a tapered face. After insertion of the post-installed anchor into a pilot hole (installation hole) bored in the concrete floor, as the bolt body rotates, the fixation member screwed to the bolt body moves toward the sleeve. This movement causes the expansion end of the fixation member to ride on the tapered face of the sleeve and to be pressed open and extended outward. The expansion pieces of the expansion end are then buckled and bite into an inner circumferential face of the installation hole, so that the post-installed anchor is securely fixed to the installation hole. | 02-17-2011 |

| 20100322738 | FASTENING APPARATUS - A fastening apparatus is provided to secure a first component to a second component. The fastening apparatus includes a fastening anchor and a securing member. The fastening anchor includes two separated securing parts defining internal screw thread and external screw thread. The securing member defines external screw thread. The securing member is accommodated into the fastening anchor by the securing member external screw thread engaging the fastening anchor internal screw thread, and the two separated securing parts of the fastening anchor is urged to expand outward to engage with one of the first component and the second component. | 12-23-2010 |

| 20090311067 | RESIN ANCHOR WITH A COMPRESSIBLE ENVELOPE CONTAINING CURABLE PRODUCTS, AT LEAST ONE OF WHICH IS SACHETED - The resin anchor comprises an apertured tubular envelope designed to be compressed by a traction element, characterized in that it includes, on the inside of the envelope, a resin component and a hardener component that are intended to be mixed together and to cure under the action of the compression of the envelope ( | 12-17-2009 |
| 20090324359 | PLASTIC ANCHOR FOR DRYWALL, PLASTER, BRICK AND CONCRETE - An anchoring device for insertion in a hole provided in a structure such as a wall (hollow or solid) comprises proximal and distal sections. The proximal section includes a head defining an aperture for receiving a fastener, and the distal section includes a pair of expandable wings displaceable between collapsed and expanded positions. Each wing is biased towards its expanded position such that the wings can engage the structural material delimiting the hole or a distal surface of the structure. The distal section comprises, proximally of the wings, a variable-length flexible portion for allowing the wings to engage the distal surface of the structure for various structure thicknesses. The distal section comprises, distally of the wings, a tip section adapted to spread outwardly when engaged by the fastener. The proximal section comprises a pair of legs each having a toothed rack for engaging the structural material. | 12-31-2009 |
