    • 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.

    • 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.
    • 一种具有螺纹构件,楔形构件和保持架构件的楔形锚固螺栓。 通过转动螺钉构件将楔形构件楔入保持架构件的端部,将螺栓锚固在钻孔中,结果是楔形构件卡在保持架构件中。 为了从空腔中弹出楔形构件,螺钉构件包括(1)一个或多个凹陷部分中的至少一个,和(2)限定步骤的一个或多个突出部分,并且保持架构件包括一个或多个相应的步进 - 接合部分用于与台阶形成干涉接触,从而进一步退出螺纹不会相对于保持架构件退出螺纹,同时相对于楔形构件继续退出螺纹,由此迫使楔形构件相对于腔体向远侧 。
