DETAILED DESCRIPTION
(24) In this disclosure, as illustrated in FIGS. 1-22, specific terminology is employed for the sake of clarity. The invention as claimed in this application, however, is not intended to be limited to specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish similar functions.
(25) Reference will now be made to the figures to describe various aspects of example embodiments of the disclosure.
(26) To gain a better understanding of the inventive features of the embodiments of a wire rope clip of the present disclosure, with reference to FIGS. 1-3 a prior art wire rope clip will first be described.
(27) FIG. 1 illustrates a prior art wire rope clip including a one-piece U bolt 100 threaded on both sides, a one-piece saddle 102, and two six-sided nuts/fasteners 104. A problem with this wire rope clip includes threads 106, which extend above saddle 102. There is nothing to stop one from over torqueing the nuts 104 or ensuring that even pressure is applied to prevent fraying or slippage. As the nut 104 tightens, pressure continues unevenly causing fraying to wire rope. The one piece saddle 102 leaves the two fasteners/nuts 104 exposed at 108 so anyone with basic hand tools can remove them. The nuts/fasteners include six sides 110 where any standard socket, adjustable wrench, or hand locking pliers can be used to remove them.
(28) FIG. 2 illustrates a side elevational view of the prior art wire rope clip of FIG. 1 and shows how the threads 106 are above the saddle 102. The threads 106 are above the saddle 102, allowing the nuts/fasteners 104 the ability to raise up past torque and unevenly. As shown at 204, the saddle 102 has the ability to freely move up and down to any height. As shown at 206, the exposed nut 104 can be taken off or loosened easily with basic hand tools.
(29) FIG. 3 is a side elevational view of a rope clip system 300, which includes the prior art wire rope clip(s), properly put together with the problems described above. The rope clip system 300 includes a dead end 302 of the wire or the end of the cable and a live end 304 of the cable which holds the pressure of the wire rope. At 306, the clamps are exposed and, if loosened, the live end 304 will slip because of the tension put on by the come a long causing the live end 304 to loosen, thus, creating a fall hazard.
(30) With reference to FIGS. 4-22, and initially FIGS. 4-15, embodiment(s) of a wire rope clip 50 will be described. The wire rope clip 50 includes a one piece U bolt 400 with threads 404 on both ends. The U bolt 400 includes stops 402 that will seat to saddle 500 on both sides to ensure proper torque specifications and even force onto the cables. The installer will be able to visually see that both sides are even and seated properly. The threads 404 are on both ends of the U bolt 400 and stick out of the bottom of a cavity of saddle 500. Nuts/fasteners 600 are threaded onto the U bolt 400 at this point.
(31) With reference to FIG. 5, a saddle 500 is contoured to hold the wire rope. The saddle 500 includes two holes 502 through which the U bolt 400 passes through the saddle 500. Added grooves 504 create grip on the live end of the rope to help prevent slipping. The saddle 500 includes sides 506 that cover the nuts/fasteners 600 and protects them from being loosened with basic hand tools. A small recess 508 in the saddle 500 enables the wire rope clip 50 to be installed faster by giving the installer the ability to control socket 1200. It allows extra room to physically feel the nut/fastener 600 upon installation and re-checking of nuts 600 to torque specifications, and to make sure the nuts 600 have not backed off or loosened. A cutout 510 on the side of the one piece saddle 500 is typical to both ends and allows the installer to visually see the nut/fastener 600 and physically feel it with their fingers to ensure the nuts/fasteners 600 are tight upon installation and re-checking of tightness. The opening will be big enough to visually see and physical feel the nut but small enough that someone cannot put a tool around the nut/fastener 600 for removal or loosening. A stop contact/engagement member/portion 512 of the one piece saddle 500 of the wire rope clip 50 seats to the stop 402 on the one piece U-Bolt 400 to ensure proper torque and even pressure that is applied to the wire rope. It allows the installer to visually see that the saddle 500 and stop 402 have evenly seated to each other ensuring proper and even torqueing. The one piece U bolt 400 and the one piece saddle 500 will seat to each other upon tightening of the nuts/fasteners 600 and compression of the two wire rope strands.
(32) With reference to FIG. 6, locking nuts/fasteners 600 includes threads 602 that mate onto the threads 404 of the U Bolt 400. The locking nuts/fasteners 600 include a unique design/recess configuration 604 that the custom socket 1200 mates so that the nuts 600 can only be removed by the custom socket 1200.

The ears/stops 702 on each side of the one piece U Bolt 700 allow the one piece saddle 703 to meet the stops 702 on the one piece U bolt, seating to each other creating proper tension and even pressure to the wire rope clip as it is fastened. The saddle 703 includes sides 704. At 706, a point at which the even seating of the stops 702 on the one piece U Bolt 700 and the one piece saddle 703 seat to each other creating proper torque and even pressure. The installer can visually inspect that the two parts have properly seated and are even. Thus, creating proper compression of the wire rope. At 708, the one piece saddle 703 is designed to cover the nuts/fasteners 708 typical on front and back denying access to the nuts/fasteners to prevent removal or loosening with basic hand tools. The nuts/fasteners will be recessed in the cavity of the saddle. Bottoms 710 of the one piece U Bolt 700 are threaded and are the point where the nuts/fasteners are threaded onto the wire rope clip. Recess 712 in the front/back of the saddle 703 allows for faster install of the nuts/fasteners and easier handling of the custom socket during installation and removal of the wire rope clip. It allows the installer to physically feel the nut/fastener easier ensuring the nuts/fasteners are not loose.
