Abstract: An expansion bolt including a housing member integrally formed as a single piece of material, the housing member having a base, a plurality of elongate elastic members extending distally from the base, the elongate elastic members distally terminating in respective spoons, and the elongate elastic members having thicknesses that are substantially less than thicknesses of the base and the spoons, a central shaft member extending through the housing member and terminating in a wedge member, the spoons defining a cavity for receiving the wedge member, the elongate elastic members structured to bend outwardly in response to the wedge member moving into the cavity, and a biasing member for biasing the shaft member relative to the housing member in the direction of said increasing relative translation.

Abstract: An expansion bolt and pivot and swivel mechanism therefor. The expansion bolt may have a base and a plurality of radially spreadable elongate elastic members cantileveredly projecting from the base at respective points of joinder to the base and terminating in respective spoons at respective points of joinder of the spoons, wherein the elongate elastic members have respective radially defined thicknesses at the points of joinder to the base that are substantially less than the corresponding thicknesses of the base, and respective radially defined thicknesses at the points of joinder of the spoons that are substantially less than the corresponding thicknesses of the spoons.

Abstract: A connecting and anchoring device. A cable element terminates at opposite ends in respective gate and spine cable termination structures. A gate housing houses a gating portion of the cable element and includes a locking element. The device has a first configuration in which the termination structures are locked together and a second configuration in which the termination structures can be separated from one another by manipulating the locking element. The device in at least the first configuration defines a closed aperture. A spine housing houses a spinal portion of the cable element. The spine housing is attached to the base and the gate housing is pivotally connected to the base so that the gate housing can pivot relative to the spine housing so as to change the configuration of the connecting and anchoring device between the second configuration and a third configuration in which the aperture is open.

Abstract: A connecting and anchoring device includes a cable element and one or more housings for the cable element. The cable element terminates at opposite ends thereof in respective gate and spine cable termination structures. The one or more housings include a gate housing which houses the cable element proximate the gate cable termination structure. The gate housing includes a manipulable locking element. The gate and spine cable termination structures have complementary shapes or structures and are configured to provide for changing between a first configuration of the connecting and anchoring device in which the gate and spine cable termination structures are locked together so as to inhibit separation thereof, and a second configuration of the connecting and anchoring device in which the gate and spine cable termination structures can be freely separated from one another as a consequence of manipulating the locking element.

Abstract: A wedge anchor bolt having a screw member, a wedge member, and a cage member. The bolt is anchored into a drilled hole by wedging the wedge member in the end of the cage member by turning the screw member, with the result being that the wedge member becomes stuck in the cage member. For ejecting the wedge member from the cavity the screw member includes at least one of (1) one or more depressed portions, and (2) one or more projecting portions, defining a step, and the cage member includes one or more corresponding step-engaging portions for making an interference contact with the step, so that further withdrawal of the threads ceases to withdraw the threads relative to the cage member while continuing to withdraw the threads relative to the wedge member, thereby forcing the wedge member distally relative to the cavity.

Abstract: A concrete anchor point system provides for an anchor point, a receptacle for embedding into a concrete structure for removably receiving the anchor point, and a tool for remotely installing the anchor point in the structure, or removing the anchor point from the structure. The receptacle is preferably tapered, and an anchoring end of the anchor point is preferably tapered to match.
