Detailed Description [0039] FIGS.3-5 illustrate the horizontal cable manager 150 of the present invention mounted to a standard 19” wide network rack 50. As described below, the horizontal cable manager 150 includes longer finger projections. The length of the fingers places the front surface 192 of the door 190 near the front of an adjoining vertical cable manager 100. For example, as illustrated in FIGS.3 and 4, the front surface 192 of the door 190 of the present invention is near the front surface 112 of the door 110 of the vertical cable manager 100. As a result, the overall aesthetics of the horizontal cable manager 150 mounted adjacent to the vertical cable manager 100 have improved. [0040] As illustrated in FIGS. 5 and 6, the horizontal cable manager 150 includes a body 152 and a door 190. The body 152 includes a back 154 with a plurality of fingers 170 extending therefrom. The length of the fingers 170 has been extended compared to the fingers of the prior art horizontal cable manager 80. The fingers 170 are arranged in an upper row extending from the upper portion 156 of the back 154 and a lower row extending from the lower portion 158 of the back 154. The upper and lower rows of the fingers 170 are parallel to each other and create a pathway for routing cables therein. The fingers 170 are angled toward the vertical center of the body 152 to provide a technician access to any equipment 60 installed above or below the horizontal cable manager 150. [0041] Each end 160 of the back 154 includes a plurality of holes 162 for receiving fasteners 70 to secure the body 152 of the horizontal cable manager 150 to the network rack 50. [0042] The distal end 172 of each finger 170 has either a cable management flag 174 or a hinge pin holder 182. Each cable management flag 174 includes a first member 176, a second member 178, and a third member 180. Each member of the cable management flags can differ in size, length, and shape depending on the location of the finger and the height of the horizontal cable manager. For example, as illustrated in FIG.7, the cable management flags 174 located near the ends 160 of the body 152 are wider than the cable management flags 174 located near the center of the body 152. The cable management flags 174 extending from aligned fingers 170 in the upper and lower rows are identical. [0043] As illustrated in FIG. 7, the distal end 172 of the aligned fingers 170 in the upper and lower rows include two sets of hinge pin holders 182. However, if desired, the distal end 172 of the fingers 170 could have additional hinge pin holders. The hinge pin holders 182 are generally U-shaped members 184 designed to hold a ferrous hinge pin 186. As discussed below, the hinge pin holder 182 accepts one of the hinge receptacles 200 extending from the back 194 of the door 190. [0044] FIGS. 8-11 illustrate the door 190 of the horizontal cable manager 150. The front 192 of the door 190 includes design elements similar to the design features found on the Panduit Patchrunner 2 vertical cable manager door. For example, the door 190 includes a pentagon with two right angles and chevron character lines. [0045] The back 194 of the door 190 includes a plurality of hinge receptacles 200. The hinge receptacles 200 are positioned along the top edge 196 and the bottom edge 198 of the door 190. Each hinge receptacle 200 includes a rare earth magnet 202 which allows the door 190 to attach to the ferrous hinge pins 186 held by the hinge pin holders 182 at the distal end 172 of the fingers 170 of the body 152. Each hinge receptacle 200 also includes a plurality of strengthening ribs 204. [0046] The rare earth magnets 202 and the ferrous hinge pin 186 form a magnetic hinging mechanism that allows for an effortless attachment of the door 190 to the cable manager body 152. The magnetic hinging mechanism also allows for the door 190 to easily open with a mild pulling force on either the top or bottom edge 196, 198, respectively, of the door 190. [0047] The hinge receptacle 200 and the hinge pin holder 182 are oriented in such a way as to allow the door 190 to be opened and rotated up to 190 degrees around the upper hinge pins 186 (see FIG.12) or rotated up to 190 degrees around the lower hinge pins 186 (see FIG.13). When the door 190 is opened upward around the upper hinge pins 186 past 180 degrees, the door 190 will rest in an open position against the first members 176 of the cable management flags 174 to facilitate access to the cables routed inside the cable manager body 152. When the door 190 is opened downward around the lower hinge pins 186, it can be allowed to hang downward at 180 degrees to facilitate access to cables inside the cable manager body 152. [0048] The door 190 can also be completely removed from the cable manager body 152, if desired, by pulling on the door 190 horizontally away from the cable manager body 152. [0049] FIG. 14 illustrates the horizontal cable manager 150 and the hinged door 190 of the present invention having varying heights. For example, the horizontal cable manager 150 can be designed so it is 2 rack units (2RU), 3 rack units (3RU), or 4 rack units (4 RU) high. The height of the hinged door 190 is adjusted to accommodate the heights of the various horizontal cable managers 150. [0050] FIG. 15 illustrates an alternative horizontal cable manager 210 embodiment. The horizontal cable manager 210 includes additional magnets 220 at each hinge location. The additional magnets 220 hold the door 214 in an open position by toggling the door 214 into a hold open detent position when the door 214 reaches the fully open position of about 110 degrees from closed. The hold open detent is easily defeated by applying a force to close the door 214. [0051] Another alternative embodiment is illustrated in FIGS. 16 and 17. The magnets 320 are installed in the door 314 and the cable manager body 312 in such a way that the axis of the magnetic force forms the hinge axis for the door 314. The door 314 is opened by defeating the shear magnetic attraction on the opening side and rotating the door 314 along the hinge axis formed by either the upper magnets 320 or the lower magnets 320. [0052] The door could also include a number of stiffening ribs as dictated by the door size, the necessary flexibility, and molding warp. [0053] FIG.18 illustrates a horizontal cable manager 150 and a vertical cable manager 500 of the present invention mounted to a network rack 50. FIG. 19 illustrates a partially exploded view of the vertical cable manager 500 mounted to the network rack 50 with the doors 510 removed. The doors 510 will be described below with respect to FIGS.27-30. [0054] FIGS. 20-26 illustrate the vertical cable manager 500 without the doors 510 installed. The vertical cable manager 500 is formed from finger assemblies 520, cross members 570, and stabilizing bases 600. A stabilizing base 600 is attached to the bottom of each parallel finger assemblies 520 which allows the vertical cable manager 500 to be free standing. This enables easier set up and installation of the vertical cable manager 500. [0055] The finger assemblies 520 include two injection molded finger segments 522 that are vertically joined together. Each injection molded finger segment 522 includes a lower vertical connection 524 and an upper vertical connection 530. As illustrated in FIG. 22, the lower vertical connection 524 includes two rack mounting holes 526 and a snap 528 positioned between the rack mounting holes 526. The upper vertical connection 530 includes two rack mounting holes 532 and a vertical joining receptacle 534. The finger segments 522 are joined together by the snap 528 and vertical joining receptacle 534. Mounting bolts 560 pass through the rack mounting holes 526 in the lower vertical connection 524 and the upper vertical connection 530 and are secured by mounting nuts 562. The mounting bolts 560 may also pass- through holes 52 in a network rack 50 to secure the finger segments 522 to the network rack 50. [0056] FIG. 23 is an inside view of a finger segment 522 and FIG. 24 is an outside view of a finger segment 522. The finger segment 522 includes a center spine 536 with fingers 538 and hinge fingers 542 extending from the center spine 536. The fingers 538 and the hinge fingers 542 extend from both edges of the center spine 536. Alternatively, the finger segment 522 may have a configuration where the fingers 538 and the hinge fingers 542 project from only one edge and only extend forward. [0057] The fingers 538 have an upturned flag 540 at the end to effectively contain cables between adjacent fingers 538. Hinge fingers 542 have a hinge flag or holder 544 at the end which serves to hold a metallic hinge pin 546 for interacting with the door 510 that covers the vertical cable manager 500. [0058] The center spine 536 includes additional rack mounting holes 548 and accessory mounting holes 550 at various positions along the center spine 536. The center spine 536 also includes cross member slots 552 and locking snaps 554 that receive the cross member 570. [0059] The finger segments 522 are joined together laterally using cross members 570. The cross members 570 are illustrated in detail in FIGS.25 and 26. Each cross member 570 attaches to the finger segment 522 via the geometry at the ends 572 of the cross member 570 and the cross-member slots 552 and the locking snaps 554 in the center spine 536. The cross member 570 includes connection tabs 574, stabilizing tabs 576, and locking tabs 578. Each connection tab 574 is angled so that the connection gets tighter as cross member 570 engagement in the cross-member slots 552 in the center spine 536 increases. The locking tabs 578 lock into the locking snaps 554 on the center spine 536 of the finger segments 522 and prevent disengagement of cross member 570 from the finger segment 522. The stabilizing tabs 576 prevent tilting rotation of the cross member 570. The cross members 570 can include, but are not limited to, additional features such as bridge forms 580 to use with cable management cable ties or hook and loop ties and mounting apertures 582 for cable management accessories, such as a slack spool 590 (see FIG.25). [0060] FIGS.27-30 illustrate the doors 510 of the present invention and the installation of the doors 510 on the vertical cable manager’s finger assemblies 520. Similar to the door 190 of the horizontal cable manager 150, the doors 510 of the vertical cable manager include a magnetic hinge that improves the functionality of the door 510 by allowing the vertical cable manager 500 to be easily opened and closed while providing a direct attachment to the network rack 50. [0061] The outside of the door 510 includes design elements such as a pentagon with two right angles and chevron character line. The inside of the door 510 includes magnet pockets or receptacle 512 with magnets 514 inserted therein. Pin guides 516 help to position the magnet pockets 512 against the metallic hinge pins 546 held by the hinge flag 544 of the hinge fingers 542. Door guides 518 help position the door 510 vertically at the end of the hinge fingers 542. [0062] FIG. 29 illustrates a detailed view of the magnetic hinges with the vertical cable manager door 510 in a closed position. FIG. 30 illustrates a detailed view of the magnetic hinges with the vertical cable manager door 510 in an open position. The magnetic hinges function like those found in the horizontal cable manager 190, as described above, but in a vertical orientation. Magnets 514 on the door 510 are magnetically attached to hinge pins 546 on hinge fingers 542 of the finger segment 522. When one side of the door 510 is pulled with sufficient force, the magnetic connection on that side of the door 510 is overcome and the door 510 will rotate open around the magnets 514 and hinge pins 546 on the opposite side. Closing the door 510 brings magnets 514 and hinge pins 546 together and the magnetic attraction holds the door 510 in the closed position. Complete removal of the door 510 is achieved by pulling on both sides of door 510 simultaneously so that the magnetic attraction is simultaneously defeated on both sides. [0063] The modular construction of the finger assembly allows for varying widths by using different widths of the cross member. The overall width can vary between but is not limited to 6-inch, 8 inch, and 10 inch widths. The door is constructed at a dedicated width so the door width must match the width of the finger assembly. [0064] Furthermore, while the 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. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as limitation.
