Abstract: A trench plate connector comprising a large-diameter skirt member for dissipating lateral forces, applied onto the trench plate connector, is disclosed. The large-diameter skirt member is threaded onto a stud, and can be locked onto the stud with a nut. Once the large-diameter skirt member is locked into place, one or more arms of the large-diameter skirt member can be used to apply rotational forces onto the trench plate connector to thereby secure or remove the stud of the trench plate connector from the trench plate. Each arm of the large-diameter skirt member can be impacted with a hammer, for example, to apply substantial rotational forces onto the trench plate connector for tightening or removal thereof. A unique double-threaded stud is used to accommodate the large-diameter skirt member. The double-threaded stud comprises a first thread on one end for being threaded into a trench plate, and a second thread on the other end for accommodating both the large-diameter skirt member and a securing nut.

Abstract: An anchor device for use with a security slot in a portable electronic article that provides an anchor for attaching a cable or other security device. The anchor device includes an internal member, an external member, and a securement for securing them together. The internal member includes a right angle portion inside the portable article that is approximately parallel to the inside wall.

Abstract: A self-drilling/self-tapping fastener which is suitable for attaching a sprinkler system to a metal supporting structure has a driving head and an integral shank with a threaded portion. Process-hardening and threading of the shank harden the shank to a degree of hardness that retains sufficient ductility for resisting vibration loads. The drill tip at the end of the shank and the lead threads adjacent the drill tip are locally hardened to a relatively high degree of hardness for drilling and tapping the metal support members. A graduated transition zone separates the high-hardness zone from the lower-hardness zone, which allows for a single fastener to exhibit two distinctly different material properties in one fastener. The fastener through this dual process also exhibits two distinct load-carrying capabilities.

Abstract: A wall anchor having a first inclined plane secured to a second inclined plane by a connector. The connector is resilient to allow the inclined planes to move relative to one another. The inclined planes are oriented opposite one another, in a manner which increases their combined height as the inclined planes slide in a first direction relative to one another, and which decreases their combined height as the inclined planes slide in a second direction relative to one another. A retainer is secured to the first inclined plane and is used to insert the inclined planes into a hole in a wall. After the inclined planes have been inserted, the retainer is withdrawn slightly, which causes the inclined planes to slide relative to one another and increase their combined height to wedge the inclined planes against an interior surface of the hole. In this manner, a retainer may be securely and manually anchored to a wall.
