| 20110243683 | FASTENER ANCHOR ASSEMBLY - Described herein are various embodiments of a fastener anchor assembly for securing a fastener includes a base and a recess formed in the base. The recess has a substantially non-circular cross-sectional shape. The assembly further includes an insert positionable within the recess. The insert has a substantially non-circular cross-sectional shape corresponding with the non-circular cross-sectional shape of the recess. Additionally, the insert includes a fastener opening and at least one flexible portion. The flexible portion flexes to engage the recess as a fastener moves through the fastener opening. | 10-06-2011 |
| 20120213607 | Anchoring Apparatus and Method of Use - An anchor apparatus for insertion into a pre-formed hole in an object of interest for permanent embedment in the hole. The apparatus includes: a screw pair having: (i) a screw with a screw head and (ii) a nut threadly interconnected therebetween; an anchor with a distal part and a proximal part to be received and anchored in the hole, the anchor comprising at least two fixing petals extendable from the outer perimeter of the distal part of the anchor; and a pushing tubular member with a distal part and a proximal part, the distal part of said tubular member adapted to expand said fixing petals of the anchor. | 08-23-2012 |

| 20090252571 | Expansion Dowel - An expansion dowel includes a sleeve-shaped dowel body ( | 10-08-2009 |
| 20100158633 | FIXING SYSTEM FOR CIRCUIT BOARD - An exemplary fixing system includes a plate portion and four fastening units latched on the plate portion. The plate portion defines four fixing holes having a polygonal shape. Each fastening unit includes a fixing portion having a base and a deformable portion, and an engaging portion. At least a part of the base has a polygonal shape matching the shape of the fixing hole. A slot is defined in the deformable portion or the deformable portion in cooperation with the base. A side edge of the plate portion which bounds the fixing hole is latchingly received in the slot. The deformable portion is deformable to allow said at least a part of the base to pass through the fixing hole in assembly of the fixing system until the deformable portion rebounds and the side edge of the plate portion is latched in the slot. | 06-24-2010 |
| 411026000 | Both wedges provided with thread cooperating means | 2 |
| 20090155013 | Fastener Engaged In Gaps Between Thin Sheets - A fastener engaged in gaps between thin sheets for connecting for example a fan to a heatsink is disclosed herein, which includes a plurality of side plates defining a space between two adjacent side plates, and a connection board connecting the side plates at one side thereof. The connection board has a protrusion extending toward the space between the side plates. The side plates are engaged into the gaps between the thin sheets, such as fins of the heatsink, and the protrusions are engaged into other gaps for securing the fastener to the thin sheets, in such a way that the fan can be stably screwed to the connection board of the fasteners and further mounted to the heatsink. | 06-18-2009 |
| 20100098509 | ANCHOR BOLT ASSEMBLY - An anchor bolt assembly having a generally cylindrical grip end spaced from an actuating end. The grip end has two relatively movable mating portions each having at least one complementary ramp surface. The actuating end is used to move a movable mating portion relative to a fixed mating portion in a longitudinal direction. Actuation will cause the movable mating portion to slide relative to the static mating portion and apply radial pressure at the grip end of the anchor bolt assembly remote from the actuating end. The grip end has a roughened surface on the static mating portion while the movable mating portion is smooth. The anchor bolt assembly is particularly suitable for use in tapered holes formed in concrete. | 04-22-2010 |
