  • the device shown in FIGS. 2-5 and designated broadly at 100 can indeed provide performance benefits as described.
  • the device 100 includes a flexible main body 102 having a wrapping portion 102a and a mounting portion 102b, a securing feature 104 in the form of two opposed latches extending from the mounting portion 102b, and a plurality of apertures 106. Five serially merging undulations 107a-e are present between the mounting portion 102b and the wrapping portion 102a.
  • the undulations 107a-e can provide elongation and flexibility to the device 100 when it is stretched and wrapped around one or more cables for mounting thereof to a mounting structure. Testing and observation have revealed that in many instances, the undulation nearest the mounting portion 102b (in this instance the undulation 107a) and the undulation nearest the wrapping portion 102a (in this instance the undulation 107e) experience the highest levels of stress under the load caused by wrapping.
  • the device 100 has non-uniform undulations 107a-e. More specifically, the undulation 107a nearest the mounting portion 102a has a height H (measured from root to crest - see FIG. 4) that is less than the height of the adjacent undulation 107b. The undulation 107b is shorter in height than the adjacent undulation 107c. The undulation 107c and 107d are of the same height, but undulation 107e (the undulation nearest the wrapping portion 102a) is shorter in height than the adjacent undulation 107d.
  • the undulation 107a has a width W (measured from root to root - see again FIG. 4) that that is greater than the remaining undulations 107b-e, which in this embodiment all have the same width.
  • the undulation 107a varies in thickness T (with the thickness T of the undulations being the wall thickness of the undulation as shown in FIG. 5). More specifically, the “vertical run” of the undulation 107a nearest the mounting portion 102b has a greater thickness T than the “vertical run” of the undulation 107a that merges with the undulation 107b, and that thickness tapers from larger to smaller over the “horizontal run” of the undulation 107a that spans the aforementioned “vertical runs.” The remaining undulations 107b-e have the same thickness as that of the vertical run of undulation 107a that merges with undulation 107b.
  • Performance advantages provided by the device 100 can be understood by reference to FIGS. 6-9. Simulating loading analyses were conducted on the device 100 as compared to the device 400 illustrated above. Specifically, the device 400 analyzed had three undulations 407, which were uniform in height (3.8 mm), width (6.34 mm) and thickness (1.2mm). In contrast, the device 100 analyzed had five undulations, the dimensions are which are shown in Table 1.
  • Three-dimensional CAD models were built of the devices 100, 400. Finite Element Analysis was then performed on the models, with a simulated load L of 5 lb. being applied to the third aperture 106, 406 from the undulations (see FIG. 6A) as the mounting portions 104, 404 were constrained (FIG. 6B).
  • FIG. 7 is a three-dimensional plot showing the elongation experienced by the device 100 (and in particular the elongation of the undulations 107a-e), while FIG. 8 is a corresponding three-dimensional plot showing the elongation experienced by the undulations 100 is able to achieve elongation of between 2.5 to 4.0 times greater than that of the device
  • the first undulation i.e., undulation 107a and its corresponding undulation 407 of the device 400
  • the first undulation experiences the highest level of stress.
  • a comparison can be made of the stress experienced by the ultimate undulation (farthest from the mounting portions 104, 404) vs. the adjacent penultimate undulation. (More specifically, this involves comparing the stress in undulation 107e vs. undulation 107d, and also comparing the stress in the corresponding ultimate and penultimate undulations of the device 400). As seen in FIG.
  • maximum Von Mises stress in the ultimate undulation is about 32% higher than the penultimate undulation.
  • the maximum Von Mises stress in the ultimate undulation 107e is about 26% higher than the penultimate undulation 107d (see FIG. 9). This shows a stress distribution that is more uniform, and the device 100 is less likely to crack than the device 400, even with significantly increased elongation under load.
  • the device 500 comprises a flexible main body 502 with a wrapping portion 502a and a mounting portion 502b separated by undulations 507. Securing barbs 504a, 504b are present on the mounting portion 502b at the ends of arms 505a, 505b, and a plurality of apertures 506 (see FIG. 13) are present in the wrapping portion 502a.
  • a bridge 509 extends between the arms 505a, 505b.
  • the main body 502 is similar to the main body 402 described above: i.e.., it is flexible, has and is configured to be wrapped such that the wrapping portion 502a and the undulations 507 can circumscribe one or more discrete cables 130.
  • the device 500 is secured by inserting the barbs 504a, 504b into adjacent apertures 506, with a rib or divider 508 that is located between adjacent apertures 506 positioned between the barbs 504a.
  • a brace 514 extends between the arms 505a, 505b below the bridge 509.
  • the brace 514 can provide additional strength and/or rigidity to the mounting portion 502b to maintain it in a secured position.
  • two prongs 530 extend from the arm 505a toward the other arm 505b, and a single prong 532 extends from the arm 505b toward the arm 505a. It can be seen that, when the arms 505a, 505b are brought together, the prong 532 is positioned between the prongs 530. This “tongue-in-groove” interaction can keep the barbs 504a, 504b from being inadvertently dislodged from the apertures 506 (for example, by wind loading). This phenomenon is described in, for example, U.S. Patent Application No. 17/577,570, filed January 18, 2022, the disclosure of which is hereby incorporated by reference herein in full.
  • FIGS. 14 and 15 An additional device 600 is shown in FIGS. 14 and 15.
  • the device 600 is similar to the device 500, with the exceptions that (a) the brace between the arms 605a, 605b is omitted, and (b) in a rest (i.e., undeflected) position as in FIGS. 14 and 15, the arms 605a, 605b are splayed such that the form an angle a of between about 3 and 30 degrees.
  • the splaying of the arms 605a, 605b can provide the arms 605a, 605b with additional gripping force/resistance to avoid being inadvertently dislodged when secured.
