DETAILED DESCRIPTION

[0037] Those of skill in the art will recognize that the following description is merely illustrative of the principles of the invention, which may be applied in various ways to provide many different alternative embodiments. This description is made for illustrating the general principles of the teachings of this invention and is not meant to limit the inventive concepts disclosed herein. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.

[0038] Turning to FIG. 1A, a series of brackets 10 are shown in spaced relation supporting and securing a plurality of cables 12. The brackets or harnesses 10 are secured to associated structural components S such as beams, frames or other adjacent structure. Each cable may be an electrical or optical cable, a bundle of wires, or a conduit for transporting fluids or objects, for example, pellets. As illustrated, the brackets 10 are horizontally oriented and each bracket 10 is configured to support and secure multiple cables 12. As will be appreciated from reading the present disclosure, a bracket may also be vertically oriented, or at some other angle of orientation as is needed. Additionally, a bracket 10 may be configured to support and secure a single cable or a plurality of cables 12.

[0039] FIG. 1B is an enlarged perspective view of a single bracket 10 according to aspects of the present invention. FIG. 1C is a longitudinal cross-section of that same bracket 10. FIG. 1D is a top plan view with the cables removed. As illustrated, the bracket 10 includes a body 14 with multiple sides 16, 18, 20, 22, 24 and 26, cable passageways 28 formed in the body 14, and cable support members 30a, 30b, 30c and 30d enclosing the cable passageways 28. Each passageway 28 has an open first end 32 and an open second end 34 spaced from the first end 32. In this embodiment, the first and second openings 32 and 34 of the passageways 28 are positioned on a common side 24 of the body 14. The first and second openings 32 and 34 of a passageway 28 may alternatively be positioned on different or uncommon sides. A passageway surface 36 extends continuously from the first opening 32 to the second opening 34. The passageway 28 does not have any abrupt angles or changes in direction and the continuous surface 36 forms a smooth passageway or channel from the open first end 32 to the open second end 34. Fasteners 38 are illustrated in FIGS. 1B and 1C securing cables 12 to the bracket 10. As shown the fasteners 38 are cable ties.

[0040] 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 FIGS. 1A-1D, the cable support surface 40 is concave or curved inwardly to provide increased surface area for contact with a cable 12, which would not be the case if the cable support surface 40 were flat. The cable support members 30a-30d have a first end 42, a second end 44, and a middle portion 46 positioned between the first and second ends. The first and second ends 42 and 44 are interconnected to opposite sides 18 and 22 of the body 14. More specifically, the first end 42 is connected to side 18, and the second end 44 is connected to side 22 of the body 14. The first portion 42 of the cable support member 30 is tapered, being wider at the location where it interconnects to the body 14 than at the location where it interconnects to the middle portion 46. The second portion 44 has a less pronounced taper. The tapered first and second portions 42 and 44 provide additional cable contact surface area beyond that provided by the middle portion 46 and facilitate supporting cables having a greater diameter. FIG. 1C illustrates cables 12a, 12b and 12c with different diameters. The wider surface provides greater stability for cables of a larger diameter. As illustrated in FIGS. 1A, 1B and 1C, the bracket 10 includes four cable support members 30a-30d. It should be appreciated that a bracket 10 may be made with a single cable support member 30 and single passageway 28 or with a plurality of passageways 28 and cable support members 30.

[0041] 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.

[0042] As best seen in FIG. 1C, each cable support member 30 has curved side edges 48 and 50 and a generally flat inner surface 52 (facing the passageway 28). The radius of curvature of the side edges 48 and 50 may be configured for purposes of reducing hoop stress on a fastener 38. Over time, the hoop stress on a fastener 38 can lead to a fastener 38 breaking. Hoop stress experienced by a fastener may change over time, based upon the environment in which the bracket and cable is installed. Knowing in advance the diameter of the cable, the curvature of the sides 48 and 50 can be designed to address anticipated hoop stress on the fastener 38. Because the bracket 10 can be made using additive manufacturing techniques, such as 3D printing, the cable support members 30 can be made with different shapes.

[0043] 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 (FIG. 1A). The apertures 52 may be positioned at the interior of the body 14 as seen in FIG. 1D, or may be located at a peripheral edge of the body 14. Different methods of connecting a bracket 10 to an adjacent structure will occur to those of skill in the art upon reading the present disclosure and are deemed to be within the scope of the present disclosure. Further, the bracket 10 of this embodiment includes a flat side 26 for mounting purposes. The bracket 10 may be mounted on a horizontal surface, a vertical surface or on any other surface at any other orientation.

[0044] FIGS. 2A, 2B and 2C illustrate a further embodiment according to aspects of the present disclosure. Compared to the embodiment of FIGS. 1A-1D, the embodiment of 2A-2C, the body 60 is curved for mounting to a curved surface such as a pipe or tube or other similarly shaped structure. It should be appreciated that the radius of curvature may be revised to fit the curvature of any underlying support structure. As illustrated, there are five cable support members 62 which extend between a first side wall 64 and a second opposed side wall 66. Each cable support member 62 has a uniform cross-section along its length, unlike the embodiment of FIGS. 1A-1D. More particularly, the cable support members 62 do not have tapered first and second portions. However, it should be appreciated that the cable support members 62 may have the same configuration as illustrated in FIGS. 1B-1D, or a different configuration. Each cable support member 62 has a concave or curved cable support surface 68. As seen in FIGS. 2A and 2B, the curved cable support surface 68 extends through outer sides 64 and 66 of the body 62. Multiple fastener passageways 74 are formed in the body 62 of the bracket. Each passageway 74 has a first open end 76 and a second open end 78. The open ends 76 and 78 are located on a common side of the bracket, but may be positioned on different sides. The cable support members 62 enclose a portion of the passageway 74. As shown in FIG. 2C, a continuous passageway surface 80 interconnects the first open end 76 and the second open end 78. Apertures 82 are formed in the body for purposes of mounting the bracket to an underlying support structure.

[0045] FIGS. 3A, 3B and 3C illustrate yet a further embodiment according to aspects of the present disclosure. Here, the cable support members 90 are connected to the body 92 at a point proximate the center of the cable support member 90 and are detached from the body 92 at the ends 94 and 96. The cable support member 90 is connected to the body 92 by a support wall 98. The support wall 98 bisects a recess 100 formed in the body 92 and the cable support members 90 extend away from the support wall 98. As a result, a first passageway 102 and a second passageway 104 are associated with each cable support member 90. As a result, one or two fasteners may be used with a single cable. Multiple fasteners may be relevant if the cable is subject to varying pressure loads, such as from a fluid moving through the cable. A continuous passageway surface 106 connects the first open end 108 to the second open end 110 of each passageway 102 and 104. The outer surface 112 of the cable support member is preferably concave.

[0046] 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 FIGS. 3A, 3B and 3C, while generally linear, may be non-linear, including having a constant curve, to adapt to the shape to different underlying support structures.

[0047] 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.

[0048] FIGS. 4A, 4B and 4C illustrate a further embodiment according to aspects of the present disclosure in which the cable bracket 120 orients the cables vertically. As illustrated, the bracket 120 includes a body 122 having a support plate 124 and one or more support arms 126 extending laterally outward from the support plate 124. In this embodiment, a support arm 126 comprises a pair of spaced side walls 128 and 130 and a bottom wall 132. A recess 134 is formed between the two side walls 128 and 130, and a cable support member 136 extends between the two side walls 128 and 130. A fastener passageway 138 subtends the support member 136. The passageway 138 comprises a first open end 140 and second open end 142 spaced from the first open end 140 with a continuous passageway surface 144 interconnecting the first and second open ends 140 and 142. The contour of the passageways is devoid of abrupt transitions to facilitate movement of a cable tie through the passageway 138. The upper surfaces 146 and 148 of the side walls 128 and 130 and the upper surface 150 of the cable support member 136 are aligned to support a cable. The first and second open ends 140 and 142 of the passageway 138 are positioned on a common side of the support arms 126. Apertures 152 for attaching the bracket 120 to a support structure are also provided. As illustrated, the bracket includes two support arms 126. It should be appreciated that brackets 120 made according to this aspect of the disclosure may have one, two or more support arms 126. As shown in FIG. 4A, the two support arms 126 are vertically aligned. It is within the scope of the present disclosure that the support arms 126 could be spaced laterally apart, such that one support arm 126 was not directly above another support arm 126. To accommodate laterally spaced support arms 126, the plate 124 may be wider or may be configured in different ways, as would be understood by those of skill in the art.

[0049] A further embodiment of a cable bracket 160 according to aspects of the present disclosure is shown in FIGS. 5A and 5B. Here, a plurality of support arms 162 extend from a support plate 164. The support arms 162 include an upper surface 166 that supports one or more cables. Passageways 168 are enclosed to a greater extent than in prior embodiments. A first open end 170 of the passageway 168 is located in the plate 164 and a second open end 172 of the passageway 168 is located at the distal end 124 of the support arm 162. However, the first and second open ends 170 and 172 remain accessible from a single side of the bracket 160, despite being located in different parts of the bracket 160. The passageways 168 extend through the entirety of the support arms 162. The passageways 168 also include a continuous and uninterrupted surface 176 connecting the first and second open ends 170 and 172. A plurality of apertures 178 are formed in the plate 164 to permit mounting of the bracket 160 to a structure. A series of outwardly extending posts 180 may also be included for purposes of aligning and securing the bracket to an associated support structure. The posts may be configured to expand upon insertion in a corresponding aperture in a support structure and may comprise the sole attachment mechanism.

[0050] The various embodiments of methods, devices, and systems used to secure cables have been described herein in detail. Such cable brackets are capable of being designed and constructed using other methods and of being practiced or of being carried out in various ways as will be readily understood by those of skill in the art upon review of the present disclosure. For example, it will be appreciated by those of skill in the art upon reviewing this disclosure that the cable support members and passageways described herein can all be sized for particular situations, to accommodate multiple fasteners within a single passageway, or to support multiple cables. Similarly, the brackets may be configured for use in virtually any orientation, to accommodate attachment to most all support structures, or to accommodate most any location where the bracket may be accessed from at least one direction. Such modifications and alterations of those embodiments as will occur to those skilled in the art upon review of the present disclosure are within the scope and spirit of the claimed invention, as set forth in the following claims. In addition, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
