Abstract: An improved fixed positionable toggle bolt device for fastening objects to a substrate comprising a metal anchor member having a nut portion and a selectively frangible positioning and holding assembly engaged with the metal member. The assembly comprises two elongated control legs, with the first ends of the control legs being pivotally attached to the metal member. The second ends of the control legs are movably attached to each other by an elongated undercut element interference, with movement of one leg relative to the other, effected by finger tip sliding, causing the metal anchor member to pivot from substantially in line with an insertion aperture in the substrate, to a position parallel to the substrate when the second ends of the control legs are aligned with each other. A positioning collar is engaged with both legs, holding them in place and is movable along the respective lengths of the legs.

Abstract: The fastening element uses a sleeve with a flanged end to insert in a hole drilled through an object, such as, a sign, and a structural element to which the object is to be attached. This allows the user to place the object in the position to be mounted and to drill a single hole of uniform diameter and insert the sleeve. An expandable element which either uses a plurality of bendable legs, or a pair of toggle elements, similar to a Toggle Bolt, is inserted with the sleeve to provide anchor members behind the structural element, such as a wall. The fastening element essentially allows one step drilling of a hole and securing of an object to a structure particularly in instance where access for use of a fastening nut on a bolt is not possible. The head of the bolt is of a sufficient radius to cover the flanged end of the sleeve when the fastening element is secured. The toggle element may also be used without the sleeve.

A trailing portion of the toggle member is arcuately deformed out of the plane of the leading portion by an amount which permits pivotal movement of the toggle member with respect to the axis of the screw member so that it forms a bridging contact with the threads of the screw member when the toggle member is at right angles to the screw member after passing through the members being fastened together.

Abstract: A wedge device particularly suitable for use in mounting a swimming pool light in a niche formed in a wall of the pool has a wedge member and a drive member for use in driving the wedge member between the side of the light and the wall of the niche. The drive member is pivotally mounted on the wedge member for limited slidable freedom of motion laterally as well as rotatable motion by means of a pair of trunnions which extend therefrom and fit into cylindrical sleeve bearings formed in the wedge member. A screw member threadably engages the drive member and is inserted through an aperture in the mounting ring for the light. When the screw is tightened against the mounting ring, it draws the wedge member against a side of the light and the wall of niche thereby wedging the light in place. The drive member can be rotated ninety degrees on its trunnions to change the size of the wedge provided by the wedge member thus enabling its use under different installation requirements.

Abstract: A toggle nut which is to be used in fastening objects to a blind partition, door, or wall.The toggle nut is a short, U-shaped channel with neither the inner width nor the depth being of greater dimension than the diameter of a threaded member which the channel is to receive. An elongated triangular aperture is located centrally in the base of the channel, with the long point of the aperture pointing toward an extension of the base. This extension abruptly turns up and back at a 180 degree semi-circular angle, terminating across the aperture. The terminal end of the base extension has a shallow semi-circular indentation.The open edges of the channel, along the length of the sides, are depressed slightly below points at the four corners of the sides.

Abstract: A reusable wall fastener such as a toggle bolt, which can attach articles to an apertured wall, including a bolt portion with a head and a retaining end thereon, and a captured nut threadingly engaging the bolt between the head and the end. The captured nut includes laterally extending wings or posts which are received in openings in an elongated toggle housing. The toggle housing further includes elongated and transverse apertures for respectively permitting the threading of the bolt both longitudinally and transversely through the housing. A biasing arrangement normally biases the toggle housing in a coaxial orientation with respect to the bolt in order to insert and remove the toggle bolt through the apertured wall. A cam surface on the toggle housing engages the inside face of the wall to thereby pivot the toggle housing against the bias into a position transverse with respect to the bolt so that the housing will engage the inside face of the wall as the bolt is continuously threaded into the housing.

Abstract: A hollow wall fastener using a conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt. An end cap within the anchor has an internally threaded head portion and a frangible portion which allows the head portion to separate from the rest of the end cap when the end of the bolt is threaded into the head portion, thus twisting the frangible portion until it breaks. Thereafter the head portion prevents withdrawal of the toggle bolt from the anchor. The end of the groove has a threaded portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall. Thereafter the bolt may be rotated to draw the anchor tightly against the interior of the hollow wall.
