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. These points are designed to dig into the inner surface of the partition on which the toggle nut is being used.

The tip of a threaded member is inserted through the aperture, under the clip, and is aligned in the channel. The toggle nut and the threaded member are inserted through a hole in a partition. The spring clip action will align the toggle nut parallel to the inner surface and the four raised corners will prevent spin of the toggle nut as the threaded member is tightened.

Claims

1. A toggle bolt assembly comprising:

an elongated rectangular U-shaped channel having a base and a pair of oppositely positioned side walls, said base having a centrally located opening, and at least one of said side walls having a raised pointed region;

a single leaf spring extending from an end of said base and an end of said spring being sprung back over the base to provide a spring bias adjacent to and toward said opening in said base;

an elongated screw having a tapered threaded end, said screw being threadably engaged between said end of said spring and an edge of said opening; and

the end of said spring and the edge of said opening providing the sole threaded receiver for said screw.

2. A toggle bolt assembly as set forth in claim 1 wherein said end of said leaf spring biasing toward said opening has a semi-circular notch therein sized to threadably engage said screw.

3. A toggle bolt assembly as set forth in claim 2 wherein said edge of said opening is concave.

4. A toggle bolt assembly as set forth in claim 3 wherein said channel and said leaf spring are constructed of a unitary piece of metal.
