DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The illustrated embodiments of the invention are directed to a vertical cable manager. Vertical cable manager 20 may be used to manage cable (not shown) on the front and/or the rear of any EIA network equipment rack, such as rack 21. Rack 21 may include a patch panel such as angled patch panel 23 or other active equipment such as a switch. Although FIGS. 1-19B illustrate vertical cable manager 20 used to manage cable on the front and the rear of rack 21, it is likewise contemplated that vertical cable manager 20 may be used to manage cable only on the front of rack 21.
Vertical cable manager 20 includes a backbone 22, a plurality of cross braces such as cross brace 24 connected to a plurality of horizontal rails such as horizontal rail 25, a plurality of finger sections such as finger section 26 connected to backbone 22 and two hinged doors such as hinged door 28 connected to cross braces 24, which collectively define a front vertical cable channel 30 and a rear vertical cable channel 31. As shown in FIGS. 1 and 2, vertical cable manager 20 includes four cross braces 24, sixteen finger sections 26 and two hinged doors 28 for front and rear cable management. Vertical cable manager 20 would include only two cross braces 24, eight finger sections 26 and one hinged door 28 for front cable management.
FIGS. 1 and 5 show doors 28 in a closed position, while FIGS. 2 and 4 show front door 28 in an open position. As can be seen in FIG. 2, backbone 22 extends the entire height of vertical cable manager 20. Although FIG. 3 shows backbone 22 configured to provide greater front cable capacity, backbone 22 may be configured to provide equal front and rear cable capacity. Similarly, backbone 22 may be configured to provide greater rear cable capacity.
Backbone 22 includes multiple groups of slots for receiving four slack spools 32. Preferably, slack spools 32 are plastic and snap onto backbone 22. Although FIG. 2 shows four slack spools 32 equidistantly-spaced along the height of vertical cable manager 20, slack spools 32 may be removed and repositioned to accommodate a variety of slack cable lengths. Moreover, backbone 22 includes a plurality of pass through openings 34 having rolled edges 35, which are formed using a special rollover tool that provides cable protection without the need for a separate plastic or rubber piece. Preferably, backbone 22 includes twelve pass through openings 34, as best seen in FIG. 2.
As shown in FIGS. 7 and 8, cross brace 24 includes a mounting surface 36 having hinge pin holes 38, guide surfaces 40 and a door alignment or closure aid 42. Hinge pin holes 38 are integrated into cross brace 24 to ensure pin alignment during door actuation. Due to the door weight and clearance between hinge pin 44 and hinge pin hole 38, gravity may cause the released side of door 28 to drop below mounting surface 36 of cross brace 24 and cause door 28 to bang on the abrupt guide surface 40 of hinge pin hole 38 upon closure. As best seen in FIG. 4, door alignment or closure aid 42 protrudes beyond a horizontal axis extending between guide surfaces 40. Door alignment or closure aid 42 takes advantage of the additional space in the middle of door 28 to provide a more gradual lead-in, helping to lift door 28 before door 28 abruptly contacts guide surface 40 of hinge pin hole 38. Thus, door alignment or closure aid 42 assists the alignment and engagement of hinge pin 44 into hinge pin hole 38 in cross brace 24.
FIG. 1 shows two sets of door latches 46, 48 utilized in door 28. One latch from each set of latches 46, 48 may be squeezed together to actuate door 28 as shown in FIGS. 15 and 16, thus allowing door 28 to hinge in either direction. Although FIG. 2 shows door 28 opening to the left, it is likewise contemplated that door 28 may open to the right. FIGS. 9 and 10 show return spring 50 utilized in door 28, with door skin 60 (see FIG. 6) removed for clarity. Window 58 in door skin 60 provides the necessary clearance for latches 46, 48 to slide during door actuation. As latches 46, 48 are pushed together, return spring 50 is compressed while hinge pin 44 is released from hinge pin holes 38 as shown in FIG. 16, allowing door 28 to swing open. Latch stop surface 52 of spring support door bracket 54 provides support for latches 46, 48 when door 28 is closed, as best seen in FIG. 6.
FIG. 10 shows an exploded view of the components of the door latch mechanism. In order to assemble the door latch mechanism, hinge pins 44 are inserted through hinge pin holes 38 until grooves 45 are aligned with latches 46, 48, and then latches 46, 48 are snapped onto hinge pins 44. Return spring 50 is inserted over one end of hinge pin 44, compressed, and then inserted onto the other end of hinge pin 44. FIGS. 11 and 12 illustrate hinge pins 44 positioned within hinge pin holes 38 on the top and bottom of door 28, respectively, and FIGS. 7 and 8 illustrate the top and bottom of door 28 connected to cross braces 24. Moreover, FIGS. 13 and 14 show door 28 in a closed position; whereas, FIG. 16 shows door 28 in an open position.
FIG. 17 shows a finger removed from finger section 26 shown in FIG. 18. Preferably, vertical cable manager 20 includes four fingers sections 26 on each side of front vertical cable channel 30, and four finger sections on each side of rear vertical cable channel 31. As best seen in FIG. 18, each finger section 26 includes eleven fingers 62 and occupies eleven rack units. Rack 21 shown in FIGS. 1 and 2 has forty-five rack units. Thus, four finger sections 26 occupy forty-four out of forty-five rack units. Although finger sections 26 are shown in FIGS. 1 and 2 providing cable management to the top rack unit, it is likewise contemplated that finger sections 26 may be configured to provide cable management to the bottom rack unit.
FIGS. 19A and 19B show an enlarged view of fingers 62 and base 64. Score grooves help create stress risers in fingers 62 when a breakaway load is applied. As shown in FIG. 19B, score grooves allow fingers 62 to be removed from base 64 without the use of a tool, for the purpose of creating horizontal pathways in any EIA network equipment rack. The force required to breakaway fingers 62 from base 64 can be tuned by adjusting the score groove geometry.
The disclosed invention provides a vertical cable manager having a spring-loaded, center release door latch mechanism and a door alignment or closure aid. It should be noted that the above-described illustrative embodiments and preferred embodiments of the invention are not an exhaustive listing of the form such a vertical cable manager in accordance with the invention might take; rather, they serve as an exemplary and illustrative of embodiments of the invention as presently understood. Many other forms of the invention are believed to exist.
