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.

CPC classification number: B66C1/66 , A62B35/0068 , F16B13/063 , F16B13/0891
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. The pivot and swivel mechanism may have a ring element that includes two spaced apart leg members having foot portions that turn to extend toward each other, the foot portions having respective, spaced-apart relatively enlarged ends; a swivel housing element having an open end for receiving and at least partially containing the ends of the foot portions so that the ring element can be substantially freely rotated about a pivot axis; and a capping element adapted for interlocking with the open end of the swivel housing element, the capping element having a bottom surface portion of radial symmetry about a swivel axis that is distinct from the pivot axis.
