    [0007] The present invention is directed to a bracket that is securely attached to a U-shaped ladder rung of a ladder rack.
    [0008] FIGS. 1-7 illustrate the bracket 20 of the present invention. The bracket 20 includes a rung insertion area 30 defined by two sidewalls 32, two gussets 42, and a bottom 54. Each sidewall 32 includes a top 34 and two curved arms 36. Each curved arm 36 includes an angled ramp 38 that leads to a pointed barb 40 that extends in a direction away from the sidewall 32.
    [0009] The gussets 42 include a top 44 and two sides 46. The tops 44 of the gussets 42 and the tops 34 of the sidewalls 32 are in the same plane. The gusset 42 also include angled ramps 48 that lead to a pointed barb 50 extending from each side 46. The pointed barbs 40 extending from each sidewall 32 align with one of the pointed barbs 50 extending from the gusset 42 to form narrow slots 52. The slots 52 are narrower than the thickness of the sidewalls 84 of the U-shaped rung 80 (see FIG. 9B) thereby providing an interference fit with the U-shaped ladder rung 80. Once installed, the barbs 40, 50 hold the bracket 20 in place on the U-shaped ladder rung 80.
    [0010] The bracket 20 also includes an upper member 60 with a first curved end 62 that extends from the top 34 of one of the sidewalls 32, a horizontal member 64, and a downwardly extending flange 66. The horizontal member 64 provides a tie or strap locator that receives a cushion sleeve 100 and stainless-steel tie 110 or strap to secure the cables 90 positioned thereon. The edges of the upper member 60 are coined or rounded to remove any sharp edges that could damages cables 90.
    [0011] As illustrated in FIG. 8, the U-shaped ladder rung 80 includes a top member 82 and two sidewalls 84 extending from the top member 82 to form a U-shape. The U-shaped ladder rung 80 does not include slots or holes in the top member 82 or in the sidewalls 84.
    [0012] As illustrated in FIGS. 9A and 9B, the bracket 20 is installed by holding the barbs 40, 50 against the sidewalls 84 of the U-shaped ladder rung 80. The bracket 20 is impacted with a hammer (not illustrated), or similar tool. The angled ramps 38, 48 above the barbs 40, 50 help locate the bracket and reduce the installation force required. As described above, the slots 52 formed by the barbs 40, 50 of the bracket 20 are narrower than the thickness of the sidewalls 84 of the U-shaped ladder rung 80 thereby providing an interference fit with the sidewalls 84 of the ladder rung 80. Once the barbs 40, 50 are separated or opened enough to slide up the sidewalls 84 of the U-shaped ladder rung 80, the hammer is used to tap the bracket 20 into a final position.
    [0013] As illustrated in FIG. 10, the upper member 60 of the bracket 20 is flush with the top 82 of the U-shaped ladder rung 80. The height and the length of the bracket 20 can be selected based on different manufacturing dimensions of U-shaped ladder rungs.
    [0014] As illustrated in FIGS. 11-15, after the bracket 20 is secured to the U-shaped ladder rung 80, cables 90 can be positioned on the bracket 20 and ladder rung 80. Alternatively, since the bracket 20 is positioned below the cables 90, the bracket 20 can also be installed without moving the cables 90 already positioned on a ladder rack. The cables 90 are secured to the bracket 20 by a cushion sleeve 100 and a stainless-steel tie 110 or strapping.
    [0015] The bracket 20 of the present invention is used for cable management and short circuit applications. As discussed above, the bracket 20 attaches a cable bundle 90 to a U-shaped ladder rack 80. If all three phases of AC current short out at the same time, the cables 90 repel and attract each other with forces that can be significant. The stainless-steel tie 110 or strapping holds the cable 90 together, while the bracket 20 holds the cable 90 to the ladder rung 80.
    [0016] The sections of cable 90 between the stainless-steel ties 110 or strapping expand during a short circuit due to the forces exerted on the cables 90. As the cables 90 expand, they often contact the ladder rungs 80 and exert a force on the brackets 20 holding the cable bundle 90 in place. The force is mainly in the direction toward the cable bundle 90. To hold the bracket 20 in place, a force equal and opposite in direction must be applied. Typically, this equal and opposite force would be achieved with the use of a mechanical fastener. However, the bracket 20 of the present invention does not require a mechanical fastener to hold it in place to create the equal and opposite force necessary for proper performance. The bracket 20 of the present invention creates the equal and opposite force via the reinforced barbs 40, 50. The barbs 40, 50 located on the sidewalls 32 and the gusset 42 of the bracket 20 hold the bracket 20 in place when an upward force is applied to the upper member 60 of the bracket 20. The barbs 40, 50 of the sidewalls 32 and the gusset 42 exert a force on the inner surface of the U-shaped ladder rung 80 holding the bracket 20 in place. The barbs 40, 50 hold the bracket 20 in place, hands free, while the stainless-steel tie 110 or strap is being installed.
    [0017] Furthermore, while the particular preferred embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the teaching of the invention.
