20100003101 | Wedge-type drop-in anchor assembly - A hybrid drop-in anchor includes an expansion sleeve. A split base region of the anchor body has a setting plug to be driven baseward by setting tool for preliminary setting in a borehole. The sleeve resiliently surrounds an external annular body recess of the body above a tapered base region portion, and has a clip arcuate portion extending at least most of the periphery around the external annular recess. Clip segments extend baseward from the arcuate portion. Each segment has proximal portion having a segment intrinsic radial thickness and includes a distal portion having at least one intrinsic projection, namely a boss, standing radially outwardly from the outer surface of the distal portion. The boss is raised from the outer surface of the distal portion without there being a corresponding cavity of said blank on an inner surface of the distal portion, to provide a projection of thickened total depth greater than the segment intrinsic radial thickness. 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 |

20160102696 | Flush Mount Screw Anchor - The present screw anchor advantageously has two fins radially extending from the body of the screw anchor, where the fins additionally extend above the top end of the body. This unique fin design permits the user to drive the screw anchor into the worn screw hole within a wood substrate so that the screw anchor is substantially flush or recessed within the worn screw hole. When the fins are aligned with the grain of the wood, the fins split the wood at the grain and prevent rotation of the screw anchor. Because the screw anchor is flush or recessed, the anchor does not interfere with the installation of hardware overtop the anchor, such as a hinge. Furthermore, the original screw, such as in the case of a door hinge, can be reused to create an invisible repair. | 04-14-2016 |
