The present disclosure relates to support structures or brackets for securing and organizing cable, optical and/or electrical wiring, fluid lines, and other flexible or rigid tubular structures.
Traditional cabling and wiring harnesses, cable tie mounts or brackets, by virtue of their construction or design, give rise to inefficiencies in the installation of such cabling and wiring. Use of such traditional bracket hardware is labor intensive and, as a result, installation of cabling and wiring includes an increased labor cost. Therefore, an opportunity exists to reduce cost through improvements in cable brackets that reduce cabling and wiring installation time.
One example of a traditional support structure is a P-clamp. Installation of a cable or wire using a P-clamp requires the P-shaped band first be opened and the band fitted around a cable. Next, the band must be secured to itself to enclose the cable, typically with a fastener such as a screw. Other types of clamping style brackets similarly require the installer to manipulate the bracket to surround the cable and then secure the clamp to itself to secure the cable. Both steps are labor intensive and time consuming. Also clamp-style brackets typically have a high cost due to a high part count including bolts, spacers and washers. Clamp style brackets are also inflexible due to specific diameter sizing, requiring an inventory of differently sized clamp-style brackets for use with differently sized cabling. Examples of P-clamps include part numbers 43LC1-2 to -96, available from J&M Products, San Fernando, Calif. and part number PP1S-S10-C, available from Panduit, Tinley Park, Ill.
A second example of a traditional support structure is a comb bracket. Comb brackets are more versatile in accommodating cabling of different diameters or quantities of multiple cables. Comb brackets provide a relatively wide platform to support multiple cables and utilize multiple slots formed in the platform to receive one or more cable ties. From one side of the platform, the leading end of a cable tie is inserted through one slot. From the opposite side, the leading end is then inserted through a second different slot. Returning to the first side, the cable tie is then secured to itself surrounding one or more cables supported by the platform. Comb brackets require access to the front side and backside of the bracket or platform and multiple steps simply for positioning the tie around the cable and bracket. This is a labor intensive process. In addition, the need for access to both the front and back of the bracket reduces or limits the physical locations where comb brackets may be used. In many locations where cabling is installed, there is no access to both sides of the bracket. Further, comb brackets typically cannot be utilized with hard tubing due to the effects of vibration. The nature of a flat surface will allow a small amount of lateral movement of a tube relative to a comb bracket which will create friction. This, in turn, can result in failure of the bracket, tube or fastener. An example of a comb bracket is part number MTP1S-E10-C, available from Panduit, Tinley Park, Ill.
A third example of a traditional support structure is a U-shaped cable tie mount or bracket. A U-shaped bracket, as its name implies, has a U-shape, where a cable is positioned in the interior of the U, and the two legs of the U each include a slot to receive a cable tie. A cable tie is inserted through one slot on the outside of one leg, across the open portion of the U, and then through the slot formed in the opposing leg. If the cable is present, it must be lifted out of the way to permit the cable tie to be fed through the slots in the opposing legs. Whether the cable is present or not, it is not unusual for the leading end of the cable tie to miss the slot in the opposing leg. The slots are relatively small and the cable ties are very flexible and may have a curved shape requiring multiple attempts to effectively thread the cable tie through the two slots. Examples of these type of cable tie mounts are part numbers TM1S4-C and ABMT-A-C20 available from Panduit, Tinley Park, Ill.
A fourth example of a traditional support structure is a pedestal bracket. A pedestal bracket, as its name implies, has a pedestal that extends out from a base. A cable is supported at the top of the pedestal. A channel is formed through the pedestal with openings on opposite sides of the pedestal. For installation, the leading end of a cable tie is inserted through the opening on one side and is retrieved on the opposite side of the pedestal by the installer. The cable tie is then positioned around a cable and the cable is secured to the pedestal. Often, the surface area of the top of the pedestal is small compared to the size of the cable and provides little support for the cable. An example of this type of cable tie mount is part number ABM100-A-C, available from Panduit, Tinley Park, Ill.
According to aspects of the present disclosure, a cable bracket is provided having a multi-sided body with a cable tie passageway having first and second open ends on the same side of a bracket body and a continuous passageway surface interconnecting the spaced openings to facilitate threading of a cable tie through the passageway in one motion. A cable support member is positioned between the passageway openings and is configured to receive cables of different sizes. The surface of the cable support member may be contoured, such as curved or concave, to provide increased surface area contact with a cable, thereby providing enhanced stability and support for the cable.
According to aspects of the present disclosure, a single bracket may have multiple cable support members for individually supporting multiple cables. Alternatively, a single cable support member may, in some circumstances, support multiple cables. The bracket may be configured such that the cable support members are horizontally spaced when the bracket is installed. Alternatively, the bracket may be configured such that cable support members are vertically spaced, or at any other orientation, such as at a slope or angle, when the bracket is installed. According to other aspects of the present disclosure, the bracket may have a generally linear configuration to attach to a flat surface, or may have a curved configuration, for example, to correspond to the exterior shape of a curved surface, such as a pipe.
According to aspects of the present disclosure, a cable bracket is provided having a multi-sided body with one or more recesses formed in one side and a cable support member extending across the one or more recesses to enclose a portion of each recess and thereby assist in defining a cable tie passageway subtending the cable support member. The cable support member may further have an outwardly curved outer surface, at least at the locations where a cable tie or fastener contacts the outer surface, such as the sides of the cable support member, when the cable tie is secured about a cable. The radius of the curvature may be optimized to reduce hoop stress or to promote the even distribution of hoop stress on the cable tie or fastener to reduce fatigue or failure of the secured cable tie over time. Other solutions, such as tie plates or comb brackets have sharp corners that can result in high tangential stress zones at fastener bend points.
According to aspects of the present disclosure, a cable bracket is provided having a multi-sided body with one or more recesses formed in and extending across the body such that the recesses are open ended. A support wall transects the recess and a cable support member extends outwardly from the support wall to define a cable tie passageway subtending the cable support member. The support wall may be centrally located relative to the recess or offset relative to the center line of the recess. The cable support member may extend in opposite directions or in one direction from the support wall.
According to aspects of the present disclosure, the cable support member may include a mounting plate with one or more cable support arms extending laterally away from the mounting plate. The one or more cable arms have a recess formed in the upper surface of the cable support arm and a cable support member extending across the recess to define a cable tie passageway beneath the cable support member. The support arm may include a curved upper side walls that provide additional support to one or more cables.
According to aspects of the present disclosure, the cable support member may include a curved or concave exterior surface for supporting cables of different diameters. In a bracket having multiple cable support members, the curvature of the cable support surface may be the same or may vary depending upon the size of the cables to be installed.
According to aspects of the present disclosure, the cross-sectional shape of the individual cable support members may vary along their length, for example, being wider at the end than in the middle. In one embodiment, the cable support member may have a tapered introductory section, a tapered exit section and a middle section having a constant cross-section. In other embodiments, the cable support member may have a constant cross-sectional shape along the length of the cable support member. In yet another embodiment, the cable support member may be wider in the middle than at the ends.
The cable brackets of the present disclosure may be made using additive or 3D manufacturing techniques which allows the brackets to be custom designed, configured and built for installation at any location.
Therefore, according to aspects of the present disclosure, the foregoing problems associated with currently available brackets for securing cables are overcome and a new cable bracket is provided having a variety of configurations that provide simplified installation of cables which, in turn, reduces installation time and corresponding cost.

Turning to
The first and second open ends 32 and 34 of each passageway 28 are positioned on opposite sides of the cable support member 30. Each cable support member 30 has a cable support surface 40 that is configured to receive a cable 12. In the embodiment of
A fastener 38 secures each cable 12 to the cable support member 30. The fastener 38 may be positioned in the passageway 28 prior to or after a cable 12 is positioned on a cable support member 30. Each passageway 28 has a continuous and smooth transitioning passageway surface 36, which facilitates simple threading of a fastener 38 around a cable 12 and cable support member 30. The leading end of a fastener 38 is inserted through the first open end 32 of a passageway 28 and, with minimal pressure or force, exits the second open end 34 of the passageway 28 in a direction away from the bracket 10 and is easily locatable by an installer. Installation is further simplified because the first and second open ends 32 and 34 of a passageway 28 are conveniently located proximate to and on opposite sides of each cable support member 30 and also because the first and second open ends 32 and 34 are located on the same side 24 of the body 14 of the bracket 10. Accordingly, an installer may feed or thread a fastener through a passageway in one motion and without need for accessing the opposite side of the bracket and without the need to manipulate the fastener 38 to align with the second open end 34.
As best seen in
Two apertures 52 are formed in the body 14 of the bracket 10 for purposes of securing the bracket 10 to a structural member 5 (
It should be appreciated that the support wall 98 need not be located proximate the center of the recess 100, but may be offset at its location such that the cable support member 90 may be larger on one side of the support wall 98 than the other. For example, the support wall 98 may be positioned along one side of the body 92, forming a portion of the side of the body, and the entirety of each cable support member 90 extends away from the support wall 98. As another example, the location of the bracket relative to the surrounding structure may inhibit access to one of the passageways 102 but allow access to the second passageway 104, thereby facilitating securing of cables to the bracket. It should be appreciated that the body shown in the embodiment of
Because this bracket may be made using additive manufacturing techniques, the exterior surfaces of the bracket may also be contoured to be customized to fit in locations and adapt to surrounding structures as is needed.
