    摘要: A metal collar attached in a through-hole of FRP member includes first and second collar members. The first collar member includes outer and inner circumferential surfaces. The outer circumferential surface is in contact with a hole inner circumferential surface of the through-hole. A slit is formed in a part in a circumferential direction of the first collar member. The second collar member applies a pressing force radially outward to at least a part of the inner circumferential surface of the first collar member or a pressing force to inner surfaces of the slit in a direction in which the inner surfaces separate from each other in the circumferential direction. The second collar member is held in the first collar member by reaction of the pressing force, deforms the first collar member for diameter expansion with the pressing force, and presses the outer circumferential surface against the hole inner circumferential surface.

    摘要: A toggle fastener includes an arm extending along a first axis and defining a threaded opening through the arm along a direction perpendicular to the first axis the toggle fastener. A rachet strap extends along a second axis and is pivotally coupled to the arm adjacent a proximal end of the rachet strap. The arm and rachet strap cooperate to block the arm and rachet strap from aligning. Pivoting the arm and the rachet strap relative to each other about a first direction, the angle between the first and second axes can be reduced to a first angle before further pivoting is blocked in a first blocking configuration of the toggle fastener. Attempting to pivot the rachet strap further in the first direction relative to the arm causes the rachet strap to recoverably flex.

    摘要: 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.

    摘要: Improvements in a hollow wall fastener that uses a cylindrical outer casing with an outer lip to distribute vertical load stress to the wall more efficiently by reducing high-load stress points and centering mass nearer the wall. The fastener uses arms that deploy and install in a reaching and spreading motion that allows the center of tension and load to remain closer to the wall. The housing uses channeled grooves that align the arms with the cylindrical outer casing. The fastener is adjustable prior to installation to set the thickness of the wall for an optimal grip. The arms secure the fastener by direct pressure applied from opposite directions along the z-axis, perpendicular to the interior wall. The arms can be retracted back into the cylindrical outer housing for removal of the fastener from the wall, ceiling, or floor.

    摘要: A retaining pin having a body section with an aperture therein and an actuation mechanism arranged at a first end of the body section. A pin is provided and connected at a first end to the actuation means and extending therefrom, through the aperture of the body section. An outer sleeve is arranged around the pin in contact therewith and the outer sleeve comprises an expandable section that, upon operation of the actuation means, can be expanded from a first dimension to a second dimension, wherein the second dimension is greater than the first.

    摘要: A screw insert configured for repairing a stripped screw hole. The screw insert comprises three elongated prongs each having a distal end and a proximal end. The three elongated prongs are hingedly connected to each other only at the proximal ends thereof. The three elongated prongs are equiangularly spaced from each other so that longitudinal axes thereof are spaced apart. Each of the prongs has an outer surface and an inner surface. The screw insert is transformable from an open configuration to a folded configuration. The longitudinal axes of the prongs are coplanar in the open configuration. The longitudinal axes of the prongs define an acute angle therebetween in the folded configuration.

    摘要: This invention relates to a fixing device for holding a fastener in a hole in a structure comprising an actuating part configured to engage with said fastener in use and a plurality of arms extending from and hingedly connected to the actuating part, each arm comprising a distal portion and an anchor portion between the distal portion and the actuating part. The arms are an insertion configuration formed or formable by moving the arms from an initial configuration in which the arms are splayed to the insertion configuration in which the arms are substantially aligned so that the distal portions define an axial passage and, in use, the fastener extends through the axial passage to engage with the actuating part, and cooperation of the fastener with the actuating part moves the actuating part in an axial direction towards the distal portions to cause a part of each of the anchor portions to move in a radially outward direction with respect to the axial passage to anchor the fixing device in said hole.

    摘要: An anchor assembly for wall installation includes a toggle body that is elongated along an axis, and a strap connected to and extending from the toggle body, wherein the strap includes a main segment that extends in a first direction away from an axis of the toggle body when the strap and toggle body are in an unstressed state, and the main segment is bendable down toward the toggle body such that the main segment extends in a second direction, where the second direction runs more closely to parallel with the axis than does the first direction. A locking sleeve mounted for movement along the strap toward the toggle body. The strap is substantially L-shaped and includes a small segment extending laterally relative to the main segment, wherein the small segment is seated within a recess on the toggle body.
