| 20090123251 | Powder-actuated mechanical lock concrete anchor - A powder-actuated mechanical lock concrete anchor, wherein the lower end portion of the concrete anchor is adapted to be disposed within the lower end portion of a blind bore drilled within a concrete substrate, and wherein a powder-actuated mechanical locking device is located within the lower end portion of the concrete anchor such that when the powder-actuated mechanism of the powder-actuated mechanical locking device is in fact actuated, either electrically or mechanically, the mechanical locking device will effectively be expanded radially outwardly so as to be lockingly engaged within lower side wall portions of the concrete substrate so as to in fact mechanically lock the concrete anchor within the blind bore drilled within the concrete substrate. | 05-14-2009 |
| 20090010732 | Fixing clip for joining two superimposed flat components - The invention relates to a fixing clip for joining two superimposed flat components each having one penetration in alignment with the other. The fixing clip is characterized by a mounting part with two arms for contact with the upper component and an expanding part attached to the mounting part for spring-loaded engagement of the lower component, wherein the mounting part with the expanding part forms a hole passage in alignment with the penetrations and the mounting part receives a cap screw, wherein said cap screw penetrates the two penetrations and the hole passage with a threaded shank and is adapted with its head between the two arms to engage the arms both in a pre-assembly position and also in a holding position. As the screw is screwed into the hole passage and as the expanding part expands, the screw transitions out of the pre-assembly position into the fixing position, in which the threaded shank holds the expanding part in its expanded position and presses the two components together. | 01-08-2009 |
| 20150063942 | EXPANDABLE FASTENER - An expandable fastener provides a fastener having a hollow tube in fluid communication with a flexible membrane forming a bladder around the tube. After the tube is inserted into the panel the bladder is filled with a curable fluid such as an expanding foam, which inflates the bladder against the rear surface of the panel. When the fluid cures it forms a substantially inflexible retaining block that contacts the panel over a large surface area, distributing any longitudinal pulling force applied against the fastener over a broad area of the panel to improve resistance to dislodgment and minimize panel failure. | 03-05-2015 |

| 20090252570 | BENCH ANCHOR - A workbench anchor utilizing counter acting wedges configured to expand laterally as they are drawn together longitudinally in order to lock the anchor in a workbench dog hole or other suitably sized hole by tightening a screw that passes through one wedge and into a threaded hole in a second wedge. Another threaded hole in the anchor can receive a screw or bolt for securing work pieces, jigs, fixtures or other structures to the anchor and, thereby, to the bench in which the anchor or anchors are mounted. An optional O-ring or other friction-increasing structure facilitates securing the anchor in and removing the anchor from the workbench by preventing the anchor from falling through the dog hole or other hole in which it is being positioned or from which it is being removed. | 10-08-2009 |
| 20110110743 | Plug with Fixing Element and Sleeve - The invention relates to a fixing device for anchoring in a building material, comprising a fixing element with an axial conical anchoring region and a fixing region and a radially flexible clamping sleeve which may be clamped between the anchoring region and the building material. The invention further relates to a method for anchoring the fixing device. | 05-12-2011 |
| 20110135418 | SELF EXPANDING FASTENER - In one embodiment a method to join a first structure to a second structure, comprises aligning a first hole in the first structure with a second hole in the second structure and inserting a fastener into the first hole and the second hole. The fastener comprises a shape memory alloy which was formed into a first shape having a diameter slightly larger than a diameter of the first hole and the second hole when the shape memory alloy was in an austenite state and reduced to a second shape having a diameter less than the diameter of the first hole and the second hole when the shape memory alloy was in a martensite state. The method further comprises heating the fastener above an austenite start transition temperature, such that the fastener initiates free expansion from the second shape back to the first shape and establishes physical contact with the surface of the first hole and the second hole and continuing to heat the fastener such that first structure and the second structure proximate the holes and the fastener undergo plastic deformation. | 06-09-2011 |
| 20120237313 | FIXING ELEMENT - The invention relates to a fixing element ( | 09-20-2012 |
| 20120251262 | Fully Grouted Mine Roof Bolt With Expansion Anchor - A reinforcement system characterized by being formed by a standard helical rod, an expansion head adapted to the thread of the rod, a conical element made of a plastic material, a tube or sheath made of corrugated plastic, a reinforcement plate, and a standard threaded reinforcement nut, according to the helical rod employed, in order to provide immediate mechanical anchoring and the option of subsequent mortar injection. | 10-04-2012 |
| 20130280005 | RIVET FASTENER - A rivet fastener includes a fastener body and a fastener pin which is inserted into the fastener body. A head of the fastener body defines a channel for receiving a head of the fastener pin, with lateral lands of the fastener body head exposed outwardly of sides of the fastener pin head. The exposed surface of the fastener body head defines hollows or recesses to accommodate tips of fingers of an installer. | 10-24-2013 |
| 20140017025 | SMART MATERIAL ACTUATED FASTENERS - A smart material actuated fastener is provided. In another aspect, a fastener includes a shape memory material and a non-shape memory material with the shape memory material being a minority of the total fastener materials. A further aspect provides a fastener having workpiece-engaging surfaces made of an inactive and non-shape memory material. | 01-16-2014 |
| 20150086290 | LIGHT LOAD COMPRESSION LIMITING FASTENING SYSTEM - A compression limiting fastening system incorporating a spring element and cooperating compression limiting sleeve adapted for substantially coaxial receipt of a fastening element through a fastened component so as to apply a relatively light load to an outer surface of the fastened component during the fastening operation. Once fastened down, the compression limiting sleeve supports the fastening load while the spring element applies a relatively light opposing load to the fastened component. | 03-26-2015 |
