Description
- This application is a continuation of U.S. application Ser. No. 12/779,439, filed May 13, 2010, and claims priority to U.S. Provisional Application No. 61/179,483, filed May 19, 2009 and U.S. Provisional Application No. 61/219,433, filed Jun. 23, 2009, the subject matter of which is hereby incorporated by reference in its entirety.
- The present invention relates to a wire cable tray system and, in particular, the invention relates to a telescoping wire cable tray system with adjustable length wire cable trays to accommodate various overhead applications.
- Wire cable tray systems are used in data centers and other areas to run cables overhead or below raised floors. Cable tray systems are generally shipped in long sections (e.g., 10 feet) and cut to fit during installation. Cutting and deburring cable trays during installation is very time consuming, and the cut ends can be sharp.
- Therefore, there is a need for a cable tray system that allows for adjusting the length of the cable trays without cutting the cable trays during installation.
- A wire cable tray system comprised of a plurality of wire cable trays and at least one trapeze support device for supporting the wire cable trays. The wire cable trays include a plurality of transverse wires and a plurality of longitudinal wires. The trapeze support device includes a trapeze support bar and at least one locking clip. The trapeze support bar includes a channel defined by a bottom and side walls extending from the bottom. The side walls include an upper support surface and a lower support surface. The locking clip slides over the channel to secure the trapeze support device to the wire cable trays.

FIGS. 1-4 illustrate the telescoping wirecable tray system 20 of the present invention. As best seen inFIGS. 1A-C , the telescoping wirecable tray system 20 includes an outerwire cable tray 30 and an innerwire cable tray 50. Each wire cable tray includes a plurality oftransverse wires longitudinal wires transverse wires cable tray system 20. - As illustrated in
FIG. 4 , eachtransverse wire 32 of the outerwire cable tray 30 includes atop portion 34,side walls portions 36 andbottom portions 38. The outerwire cable tray 30 includeslongitudinal wires 42 positioned underneath thetop portion 34 of thetransverse wires 32. The threelongitudinal wires 42 are parallel and are positioned an equal distance apart, and they provide support to thetransverse wires 32. Alongitudinal wire 42 is also positioned above eachbottom portion 38 of thetransverse wires 32 at the end of thetransverse wires 32 thereby forming a slot or track 44 between theside walls 36 of thetransverse wires 32 and thelongitudinal wire 42. - The
transverse wires 52 of the innerwire cable tray 50 include atop portion 54 andside walls 56. The innerwire cable tray 50 includes three parallellongitudinal wires 62 positioned above thetransverse wires 52 and alongitudinal wire 62 positioned at the end of eachside wall 56 of thetransverse wires 52. - As illustrated in
FIGS. 2-3 , when the innerwire cable tray 50 is positioned in the outerwire cable tray 30, thelongitudinal wires 62 of the innerwire cable tray 50 and thelongitudinal wires 42 of the outerwire cable tray 30 are positioned adjacent to each other allowing the wire cable trays to slide or telescope with respect to each other to adjust the length of the wire cable tray system. As best seen inFIG. 3 , thelongitudinal wires 62 at the end of thetransverse wires 52 of the innerwire cable tray 50 are positioned in the slot or track 44 formed by thelongitudinal wires 42 and theside walls 36 of thetransverse wires 32 thereby restricting the relative lateral movement of the wire cable trays as the wire cable trays telescope with respect to each other. - In one embodiment, the outer and inner wire cable trays are designed with a 100 mm×9.5 in. grid spacing to enable the wire cable tray openings to align with cabinet top openings in a line of standard cabinets of various standard widths. Typically, there are three standard widths of data center cabinets. Each of these standard widths is a multiple of the distance between transverse wires of the wire cable tray. For example, the wire cable tray system openings approximately align with Panduit's NET-ACCESST™ cabinet top openings illustrated and described in U.S. Pat. No. 7,498,512.

FIGS. 5-12 illustrate the components and assembly of an alternative embodiment of the telescoping wirecable tray system 20, referred to as wirecable tray system 120. The wirecable tray system 120 includes truss style side walls to strengthen the structure of the wire cable trays. -
FIGS. 7-8 illustrate the trussstyle side walls 132 of the outerwire cable tray 130 formed by thetransverse wires 134. Thetransverse wires 134 include atop portion 136, a downwardly extendingdiagonal wall 138 which loops to form aflat bottom portion 140 and an upwardly extendingdiagonal wall 142 that ends with atransverse stub 144. Eachtransverse stub 144 is positioned adjacent to thetop portion 136 of an adjacenttransverse wire 134. Thelongitudinal wires 146 of the outerwire cable tray 130 are positioned underneath thetop portion 136 of thetransverse wires 134. Alongitudinal wire 146 is also positioned at each end of thebottom portions 140 to form a slot or track 148 (seeFIG. 12 ) between theside walls 132 of thetransverse wires 134 and thelongitudinal wire 146. -
FIGS. 9 and 10 illustrate the trussstyle side walls 151 of the innerwire cable tray 150 formed by thetransverse wires 152 and alongitudinal side wire 162. Thetransverse wires 152 include atop portion 154, a downwardly extendingwall 156 and an upwardly extendingwall 158 ending in astub 160. Eachstub 160 is positioned adjacent to thetop portion 154 of an adjacenttransverse wire 152. - The
longitudinal side wire 162 is positioned adjacent to the intersection of the downwardly extendingwall 156 and the upwardly extendingwall 158. Thelongitudinal side wire 162 includes abottom portion 164, acurved portion 166 and atop portion 168. Thebottom portion 164 of thelongitudinal side wire 162 generally extends the length of the innerwire cable tray 150. As illustrated inFIG. 11 , thelongitudinal side wire 162 is designed to slide in the slot or track 148 to provide a smooth telescoping action over the outerwire cable tray 130. - The inner
wire cable tray 150 also includeslongitudinal wires 170 that are positioned above thetop portion 154 of thetransverse wires 152. -
FIG. 13 illustrates a prior art bend radius downspout fitting 200 including atop portion 202 with abend radius portion 204 extending from one end. The bend radius fitting 200 includessnaps 206, and the bend radius fitting 200 snaps onto adjacent longitudinal wires to cover the area between adjacent transverse wires. Thebend radius portion 204 extends downward into anopen area 208 between the transverse wires. As a result, thebend radius portion 204 reduces the availableopen area 208 for cables to exit the wire cable tray system. -
FIGS. 14-16 illustrate a bend radius fitting 220 for the wire cable tray system. The bend radius fitting 220 includes abend radius portion 222, twoside flanges 224 and two snap features 226 positioned along the bottom of the bend radius fitting 220. The bend radius fitting 220 is snapped onto adjacent transverse wires. As best seen inFIG. 15 , the bend radius fitting 220 does not extend into theopen area 228, thus the entireopen area 228 is available for cables exiting the wire cable tray system.FIG. 16 illustrates cables routed from opposite directions and descending through a commonopen area 228 in the wire cable tray system. - The bend radius fitting 220 provides maximum space to route cables and cable connectors through an open area in the wire cable tray while minimizing the spacing between transverse wires in the wire cable tray, which minimizes the sag between the transverse wires of cables supported by the wire cable tray. The bend radius fitting 220 also increases the number of options for longitudinal locations of downspouts in the wire cable tray system.
