DETAILED DESCRIPTION OF THE INVENTION
[0045] Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. While the preferred embodiments have been described, the details may be changed without departing from the invention.
[0046] A mounting device that is configured to secure an elongate element, such as, such as electrical wiring, fiber optic cables, pneumatic lines, hydraulic lines and the like, to a threaded stud protruding from a structural member using a flexible cable tie is described herein. The mounting device includes a support surface that, in conjunction with the cable tie, self-centers the elongate element on the support surface. The mounting device serves to elevate the elongate element above the structural member and orient the elongate element relative to the structural member.
[0047] Referring to the drawings, and, in particular to FIGS. 1, 2 and 3, a non-limiting example of a mounting device 110 embodying the various features of the invention is shown. The mounting device 110 functions to secure elongate items 60, such as electrical wiring, fiber optic cables, pneumatic lines, hydraulic lines and the like, or a combination of any of these (as shown in FIGS. 4 and 5), to an adjacent structural member 80. The structural member 80 has a cylindrical post, such as a threaded stud 90, affixed to and protruding from its surface. It will be apparent that a bundle may comprise multiple wires or cables that are flexible or rigid, or fluid transporting hoses or tubes. Some elongate items may also be contained within a conventional tubular conduit. The mounting device 110 is particularly well suited for use in the transportation industry where it can be used to secure wiring harnesses and/or fluid carrying lines to a structural member such as a vehicle frame rail, firewall, fender, body panel, bracket or other structural members having a protruding cylindrical post, preferably a threaded stud.
[0048] As illustrated, in the views of FIGS. 1 and 4, the mounting device 110 includes four principal components, namely a cylindrical body 120, a support surface 130, an enclosed channel 140 having cable tie apertures, and a locking pawl 150.
[0049] As shown in FIG. 1, the mounting device 110 has a generally cylindrical body 120 defining a cavity 121 extending from a top surface 122 to a bottom surface 124. The bottom surface 124 has a generally circular bottom opening 125 extending into the cavity 121. The bottom opening 125 is configured to receive the threaded stud 90. The top surface 122 also has a top opening 126 extending through the top surface 122 into the cavity 121. The top opening 126 is characterized as having a generally circular central section and two rectangular sections extending laterally therefrom. There are a pair of protrusions 128 extending laterally from the cylindrical body 120 from opposite sides of the top opening 126. The top surface 122, including the protrusions 128, forms a saddle-like support surface 130 for supporting an elongate element as discussed above. As best shown in FIGS. 2 and 3, the height of the cylindrical body 120 is sufficient to allow the insertion of a threaded stud 90 through the bottom opening 125.
[0050] Now referring to FIG. 4, it can be seen that a flexible locking pawl 150 is formed within the cavity 121 of cylindrical body 120. The locking pawl 150 engages with one or more threads 92 of threaded stud 90 to secure the mounting device 110 to the structural member 80.
[0051] As best shown in FIG. 4, the elongated member 60 is attached to the support surface 130 of the mounting device 110, which can be accomplished before or after the mounting device 110 is secured to the threaded stud 90. A flexible cable tie 70 having a locking head 72 is inserted through the enclosed channel 140 in the protrusions 128 of the top surface 122. The cable tie 70 is wrapped about the elongated member 60 and the tie tail (not shown) is passed through the locking head 72 and pulled tight to secure the elongated member 60. Optionally, the excess portion of the tie tail may be cut just above the locking head 72. Other types of cable ties or straps known to those skilled in the art may alternatively be used to attach the elongated member 60 to the support surface 130 of the mounting device 110.
[0052] As further shown in FIGS. 4 and 5, the cable tie 70 secures the elongated member 60 elevated above the threaded stud 90 and structural member 80. The elongated member 60 is on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes.
[0053] A second non-limiting example of a mounting device 210 is shown in FIGS. 6 through 11. The mounting device 210 has a substantially similar cylindrical body 220 and locking pawl 250. The mounting device 210 incorporates an alternatively saddle-like support surface 230. The support surface 230 has a robust top surface 222 having an enclosed channel 240 and side support surfaces 226 having enclosed channels 244, 246. These channels 240, 244, 246 are configured for receiving cable ties 70. As shown in FIG. 9, the benefits of the mounting device 210 include allowing the cable tie 70 to span through the channel 240 in the cylindrical body 220 below the support surface 230. The cable tie 70 secures the elongated member 60 elevated above the threaded stud 90 and the structural member 80. The elongated member 60 is on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes. As shown in FIGS. 10 and 11, additional elongated members 60 may be secured to the side support surfaces 226 of the mounting device 210 by inserting a cable tie 70 through the channel 244 and/or the channel 246. The elongated members 60 may be secured to the side support surfaces 226 either parallel to cylindrical body 220 (longitudinally) by using the enclosed channels 246 or perpendicular to cylindrical body 220 (laterally) by using the enclosed channels 244. Like the elongated members 60 described above, any elongated members 60 mounted to the side support surfaces 226 is also on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes.
[0054] A third non-limiting example of a mounting device 310 is shown in FIGS. 12 through 17. The mounting device 310 has a X-shaped body 320. Similar to the first and second mounting devices 110, 210, the X-shaped body 320 also includes a substantially similar locking pawl 350 in each leg of the X-shaped body 320. The mounting device 310 incorporates a saddle-like support surface 330 similar to that of the second mounting device 210. The support surface 330 has a robust top surface 322 having an enclosed channel 340 and side support surfaces 326 having enclosed channels 344, 346. These channels 340, 344, 346 are configured for receiving cable ties 70. As shown in FIG. 15, the benefits of the mounting device 310 include allowing the cable tie 70 to span across the channel 340 in the X-shaped body 320 just below the support surface 330. The cable tie 70 secures the elongated member 60 elevated above the threaded stud 90 and structural member 80. The bundle is on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes. As shown in FIGS. 16 and 17, additional elongated members 60 may be secured to the side support surfaces 326 of the mounting device 310. Elongated members 60 may be secured to the side support surfaces 326 either parallel to the X-shaped body 320 (longitudinally) by using the channels 346 and/or perpendicular to the X-shaped body (laterally) by using the channels 344. Like the elongated members 60 described above, any elongated members 60 mounted to the side support surfaces 326 is also on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes.
[0055] A fourth non-limiting example of a mounting device 410 is shown in FIGS. 18 through 22. The mounting device 410 has a body 420 with L-shaped through-holes 444. Mounting device 410 preferably includes two locking pawls 450 that oppose each other while engaging onto a threaded stud 90 and that can be viewed through the through-holes 444. The through-holes 444 allow access to the locking pawls 450 so that the locking pawls 450 may be released from the threaded stud 90, for example by using a tool to flex the locking pawls 450 away from the threaded stud 90, to allow removal of the mounting device 410 from the threaded stud 90. Mounting device 410 has a cavity 421 with a closed end and a predetermined inner diameter 434 for a close fit around threaded stud 90. The top surface 422 includes a pair of protrusions 428 that form a saddle-like support surface 430 for supporting an elongated member 60. The protrusions 428 also preferably includes cut-out side portions 429 designed in a particular geometry for ease of installation. Underneath support surface 430 is a channel 440 for cable ties 70 to be threaded through to secure the elongated member 60 to the mounting device 410. As shown in FIGS. 21 and 22, the cable tie 70 secures the elongated member 60 elevated above the threaded stud 90 and structural member 80. The elongated member 60 is positioned to longitudinally extend over each protrusion 428, and is on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes.
[0056] A fifth non-limiting example of a mounting device 510 is shown in FIGS. 23 through 29. The mounting device 510 has a cylindrical base portion 520 that tapers 527 toward the top surface 522 of the mounting device 510. Mounting device 510 includes rectangular through-holes 544, through which locking pawls 550 and threaded stud 90 can be viewed. Mounting device 510 preferably includes two locking pawls 550 with a plurality of teeth 552 designed to fit around at least two different threaded stud sizes (see FIGS. 26 and 29). Locking pawls 550 oppose each other while engaging onto a threaded stud 90. The through-holes 544 allow access to the locking pawls 550 so that the locking pawls 550 may be released from the threaded stud 90, for example by using a tool to flex the locking pawls 550 away from the threaded stud 90, to allow removal of the mounting device 510 from the threaded stud 90.
[0057] As best shown in FIG. 26, mounting device 510 has a cavity 521 with a closed end. A first portion 534 of the cavity 521 has a predetermined inner diameter for a close fit around threaded stud 90, and as shown best in FIG. 29 and a second portion 536 with a smaller inner diameter configured to fit a threaded stud having a smaller diameter than the threaded stud 90. The circular top surface 522 acts as a support surface for supporting an elongated member 60. Underneath top surface 522 there is a channel 540 that is defined between a pair of opposed standoffs 528 through which a cable tie 70 is threaded to secure the elongated member 60 to the mounting device 510. As shown in FIGS. 26 and 29, the cable tie 70 secures the elongated member 60 elevated above the threaded stud 90 and structural member 80. The elongated member 60 is positioned to longitudinally extend in-line with standoffs 528, and is on-center or in-line with the threaded stud 90 which is beneficial for harness routing purposes. The circular support surface 522, the standoffs 528, the channel 540, and the cable tie 70 cooperate to allow 90 degrees of rotational freedom of the elongated member 60 relative to the mounting device 510. This provides the benefit of rotational tolerance of the elongate element without the need to rotate the mounting device 510 which could tighten the mounting device 510 to the structural member 80 causing undesirable deflection of the pawls 550 or loosen the mounting device 510 from the structural member 80 allowing undesirable movement of the mounting device 510. The standoffs 528 allow 90 of rotational alignment freedom of the cable tie 70 in relation to the mounting device 510 in order to provide greater freedom in aligning the elongate structure 60 relative to the structural member 80. The standoffs 528 are preferably offset by a 45 rotation relative to the locking pawls 550.
