After the setting plug is driven baseward, the threaded male member is inserted and tightened. Pulling movement of the anchor with contact of the segments with the borehole walls moves the expansion sleeve baseward, such that each segment rides radially outwardly resiliently on the tapered portion for baseward radial expansion of the anchor to cause corresponding locking, wedging engagement of each segment projection with wall surfaces for permanent setting of the anchor assembly in the borehole with increased tightness providing enhanced pull-out resistance. | 01-07-2010 |
| 20110052343 | FASTENING ELEMENT AND METHOD FOR PRODUCING A FASTENING ELEMENT - A fastening element and a method for producing a fastening element is disclosed. The fastening element includes an elongated base body and a connecting sleeve on one end of the base body, which features a connecting section for a prestressing element. The connecting sleeve is fixed on the base body by rolling. | 03-03-2011 |
| 20100303578 | DROP-IN ANCHOR - A drop-in anchor system includes a drop-in anchor having a tubular sleeve with a first end and an expandable second end. The sleeve tapers in inner diameter from the first end to the second end at a sleeve taper angle. The drop-in anchor includes a plug insertable in the sleeve such that when the plug is driven into an installed position in the sleeve the second end expands. The plug tapers at a plug taper angle from a head end to a tip end and a difference between the sleeve taper angle and the plug taper angle is about one degree or more. The system includes an installation tool configured to form a hole in a workpiece into which the drop-in anchor is insertable and to drive the plug into the installed position in the sleeve. | 12-02-2010 |
| 20100303577 | Drop-In Anchor - A drop-in anchor includes a tubular sleeve having a first end and an expandable second end, the sleeve having one or more raised surfaces at the first end. A plug is insertable in the sleeve such that when the plug is driven into an installed position in the sleeve the second end expands and an installation tool interacts with the one or more raised surfaces to provide a visual indication of engagement of the drop-in anchor to a workpiece. | 12-02-2010 |
| 20120308326 | Self-Drilling Anchor Screw - A unique self-drilling anchor screw is configured so that it can be set and used to secure a first object to a second object using only one tool to save time and effort. A nut of the screw engages a nut stop when turning in reverse, thereby driving rotation of the screw in reverse. The screw has a drill bit tip adapted for drilling a hole while turning in reverse. A hole is drilled using the drill bit tip while turning the nut in reverse with a socket wrench of the one tool. After drilling the hole, the nut is turned in the forward direction with the socket wrench to engage a sleeve member of the screw, which sets the screw in the second object. Then, the nut is further turned forward using the socket wrench to tighten the nut against the first object located between the nut and the second object. | 12-06-2012 |
| 20120148365 | PUSH RIVET - A push rivet used to secure members to be mounted includes a rivet body and a pin. Rivet body includes at least a flange portion provided with an insertion hole; a pair of first divided leg portions projecting from the flange portion to an end side; at least a pair of second divided leg portions projecting from the flange portion to an end side to form slits between the pair of second divided leg portions and the pair of first divided leg portions; and bulging portions respectively projecting from end parts of the first divided leg portions and the second divided leg portions to an inner side, the bulging portions having tapered surfaces inclined to project inwardly to the end side. The pin includes at least a head portion to fit into the flange portion; a shaft portion formed to project from the head portion to the end side and having a cavity therein; corner portions provided on side surfaces of the shaft portion to slidably fit into the slits; and dented grooves to engage the bulging portions of the second divided leg portions to diametrically enlarge the second divided leg portions. | 06-14-2012 |
| 20120099942 | ANCHOR - An anchor is provided and includes a hub having a trailing edge, and first and second jaws, each including a body pivotably coupled to the hub and an actuator to induce pivoting of the body, the jaws being initially proximal with the bodies cooperatively forming a lead profile such that the jaws and the hub are configured to penetrate a substrate, separable responsive to fastener insertion through the hub whereby the fastener exerts a first force on the actuators causing splay pivoting of the bodies, and at least partially closeable responsive to continued fastener insertion whereby the fastener exerts a second force on the actuators causing reverse pivoting of the bodies to draw the trailing edge toward the actuators about the substrate. | 04-26-2012 |

| 20100086376 | Expandable collet anchor systems with captive studs - A collet body and captive stud combination is disclosed wherein the collet body has a first end and adjacent first wall portion, and a protrusion extending from an exterior surface thereof. The first wall portion also defines at least two secondary slots to create at least two fingers. The collet body also has a second end including a collet head and an opening for receiving a stud. At least a portion of an interior surface of the collet body is threaded to rotationally receive a threaded stud. The stud includes a head, a body portion being at least partially threaded, a distal end and at least one radially extending protrusion at or proximate to the distal end. The protrusion may be circumferentially continuous or discontinuous. The stud body portion is sized to fit through the collet body second end, and to prevent dislocation of the stud from the collet body once inserted in a collet body, the maximum diameter of the stud at the radially extending protrusion is greater than the minimum diameter of any essentially non-elastic portion of the collet body. | 04-08-2010 |
