The disclosure relates to fastening devices and more particularly pertains to a new fastening device for fastening one substrate to another.
The prior art relates to fastening devices. Prior art fastening devices, which may comprise locking nuts having both internal and external threading, do not teach the base features of the present invention.
An embodiment of the disclosure meets the needs presented above by generally comprising a cylinder, which has a first end and a second end. The cylinder is circumferentially larger proximate to the first end, thus defining a first section and a second section of the cylinder. External threading is positioned on the second section and extends from the second end toward the first section. The external threading is reversed so that the cylinder is configured for counterclockwise rotational insertion into a first hole positioned in a first substrate. The first section of the cylinder abuts a first face of the first substrate and the second end of the cylinder is accessible from a second face of the first substrate. A channel, which is internally threaded, extends into the cylinder from the second end. The channel is configured for clockwise rotational insertion of a threaded fastener, which is engaged to a second substrate, to engage the second substrate to the second face of the first substrate.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The disc 24 may have a plurality of serrations 28 extending into a lower face 30 thereof to define a plurality of teeth 32, the function of which will become apparent. The first section 18 can be formed to provide screwheads 26 that are complementary to any of a variety of driver types, such as, but not limited to, flathead screwdrivers, Philips screwdrivers, Allen wrenches, and the like.
External threading 34 is positioned on the second section 20 and extends from the second end 16 toward the first section 18. The external threading 34 may extend to the first section 18, as shown in
In a first example where the first section 18 is formed as a screwhead 26 that is tapered, as shown in
In a second example where the first section 18 is formed to include a disc 24 bearing a plurality of teeth 32, as shown in
The second section 20 of the cylinder 12 may taper from the first section 18 to the second end 16 of the cylinder 12, as shown in
A channel 36, which is internally threaded, extends into the cylinder 12 from the second end 16. The channel 36 may extend to the first end 14 of the cylinder 12. The channel 36 is configured for clockwise rotational insertion of a threaded fastener 38, such as a bolt, as shown in
While the device 10 is structurally similar to screw-in type anchors used with screws for attaching articles to a substrate, it is differentiated by the external threading 34, which is reversed relative to that of screw-in type anchors. Additionally, the channel 36 is internally threaded to accept the threaded fastener 38 from the second end 16 of the cylinder 12, which is opposite to how screw-in type anchors are used. Ultimately, the device 10 facilitates engagement of a second substrate to the second face of a first substrate, whereas a screw-in type anchor would be used to engage a second substrate to a first face of the first substrate.
The device 10 may comprise a locking element 40, which is positioned in the channel 36 and which is engaged to the cylinder 12. The locking element 40 is configured to engage the threaded fastener 38 to deter counterclockwise rotation of the threaded fastener 38, which serves to resist loosening of the threaded fastener 38 due to vibrations and torque. The locking element 40 may be positioned proximate to the first end 14 of the cylinder 12, as shown in
In use, a first hole is created in the first face of the first substrate and the cylinder is threadedly inserted thereinto using counterclockwise rotation. The second substrate having the threaded fastener 38 engaged thereto is positioned proximate to the second face of the first substrate so that the threaded fastener can be threaded into the channel 36. Tightening of the threaded fastener 38 engages the second substrate to the first substrate.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
