BACKGROUND OF THE PRESENT INVENTION
1. Field of the Present Invention
The present invention relates generally to cable management systems for telecommunications cables, and, in particular, to horizontal cable managers having adjustable internal components for better cable management.
2. Background
Racks, frames, cabinets and the like for supporting computer and other electronic equipment are very well known. Similarly, raceways for routing cables and wires to and from that equipment are likewise well known. In particular, a number of raceways have been proposed for routing cables, wires and the like (generally referred to hereinafter as “cables”) vertically through or adjacent to equipment racks, frames, cabinets and the like (generally referred to hereinafter as “mounting fixtures”). Such raceways may be used to route cables vertically to equipment mounted or otherwise supported on a mounting fixture from other equipment on the mounting fixture, from an overhead or underfloor raceway, or the like. These cables are generally routed in the vertical direction to a point adjacent to the desired equipment and then routed in the horizontal direction to the desired equipment.
An important characteristic of such raceways is the presence of a plurality of openings in the sides of the raceway through which cables may be routed, thereby facilitating more convenient access between the equipment and the interior of the raceway. For example, U.S. Pat. No. 2,921,607 to Caveney, U.S. Pat. No. 3,705,949 to Weiss, commonly-assigned U.S. Pat. No. 7,119,282 to Krietzman et al., and U.S. Pat. No. 7,285,027 to McGrath et al. each disclose a covered wiring duct or wireway which includes side walls having a series of finger-like projections separated by openings. The cables may be routed through the openings by bending them around the projections, thus allowing the cables to be routed with relative precision, and preventing cables from hanging loosely across the face of the rack itself. A gap at the distal ends of each pair of adjacent projections permits cables to be inserted into each respective opening. The gap is narrower than the opening, thus aiding in the retention of the cables within the opening.
The distal ends of all the projections may then be covered by a cover, thus providing further retention capability. The covers are typically hinged, oftentimes along each of two sides, so that they may be conveniently opened from either side. The hinge structure may be supported by the projections or may be supported separately. In either case, however, the hinges, if not the doors themselves, are arranged such that when opened, they can create interference with other cable managers or other equipment or accessories immediately adjacent thereto. This either creates interference for the user or necessitates that each cable manager must be spaced from other interfering cable managers, equipment or accessories.
Thus, a need exists for a hinge structure, for a horizontal cable manager, whose operation does not interfere with adjacent cable managers, equipment, or accessories.

DETAILED DESCRIPTION
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, in which like numerals represent like components throughout the several views, the preferred embodiments of the present invention are next described. The following description of one or more preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
FIG. 1 is a front plan view of a mounting fixture system 10 utilizing a horizontal cable manager 30 in accordance with one or more preferred embodiments of the present invention. As shown, the system 10 includes a conventional two-post mounting rack 20 on which are mounted two horizontal cable managers 30. The two-post mounting rack 20 includes a pair of vertical support members 12,14, connected at their upper ends by a pair of upper cross-members 16 and at their lower ends by a pair of lower cross-members 18. The posts 12,14 are arranged to support a variety of electronic equipment, accessories and the like, all as is well known.
It will be apparent to the Ordinary Artisan that the arrangement illustrated in FIG. 1 may be a preferred implementation of one or more of the horizontal cable managers described and illustrated herein. However, it will be appreciated that the horizontal cable manager of the present invention may be utilized with a variety of mounting fixtures, for example including mounting fixtures formed from four support posts that may or may not be covered by panels to form an enclosure; and that additional mounting fixtures may be alternatively located on one or both sides of the mounting fixture on which the cable manager 30 is mounted.
FIG. 2 is a front isometric view of one of the horizontal cable managers 30 of FIG. 1, shown in isolation. As shown therein, the horizontal cable manager 30 includes a trough 32, formed by a pair of side cable guides 41,42, and a door 38. Each of these components will be described in greater detail herein.
FIG. 3 is an isometric view of the trough 32 of FIG. 2. Each side cable guide 41,42 has a plurality of T- and L-shaped rib or finger projections 63,64 extending forwardly from a horizontal support member 46. A central post 81,82 and two end posts 83,84 extend orthogonally from the horizontal support member 46 toward the other cable guide 42,41. Passthrough openings 85 are defined between the posts for the purpose of routing cables and other wires from the interior of the trough 32 through to the rear.
The two side cable guides 41,42 are generally similar to each other except for the lengths of the central posts 81,82 and end posts 83,84. In the embodiment illustrated in FIG. 3, the upper side cable guide 41 is larger than the lower side cable guide 42. It will be appreciated, however, that two of the larger side cable guides 41 may be combined together to make a larger trough 132, and that two of the smaller side cable guides 42 may be combined together to make a smaller trough 232. FIGS. 4 and 5 are end views of a trough 132 comprised of two of the larger side cable guides 41 and a trough 232 comprised of two of the smaller side cable guides 42, respectively.
Referring again to FIG. 3, each T-shaped projection 63 includes a shaft 66 and a full crosspiece 67, while each L-shaped projection 64 includes a shaft 66 and a half crosspiece 62. Each pair of adjacent T-shaped and L-shaped projections 63,64 defines a cable ring 68 formed by the respective shafts 66 and crosspieces 67 of the projections 63 and the body of the support column 46. An opening into each cable ring 68 is provided by a gap 69 between the ends of the crosspieces 67 of each pair of adjacent projections 63. This gap 69 permits cables to be inserted into the ring 68 by passing them sideways through the gap 69, as described further in commonly-assigned U.S. Pat. No. 7,119,282 to Krietzman et al., the entirety of which is expressly incorporated herein by reference.
As illustrated in the top row of projections 63,64 in FIG. 3, the shaft 66 of each projection 63,64 utilizes a reinforced construction characterized by a series of interlocking crescent-shaped reinforcement walls or ribs 65. This geometry is designed to minimize deflection under load in the vertical, horizontal, and twist directions. The finger cross section is U-shaped which gives the greatest strength in the vertical and horizontal direction. The interior ribs 65 are designed to minimize the twist and to also add strength in the vertical and horizontal direction.
The respective projections 63,64 are evenly spaced along the length of the horizontal support member 46 at a standardized spacing. In the embodiment shown and described, the spacing between the respective projections 63,64 is equal to a single standard rack mounting unit (“RMU”) (conventionally, 1.75 inches), but it should be obvious that other standard spacings could be used such as spacings measured in alternative units or spacings which are multiples of the RMU. By using such a standard spacing, it is ensured that a cable ring 68 is disposed at, and dedicated to, each RMU along the width of a rack 20. Benefits of this arrangement are further described in U.S. Pat. No. 7,119,282.
Furthermore, the sizes of the side cable guides 41,42 are preferably also selected to correspond to standardized units. In particular, the combination of one large side cable guide 41 and one small cable guide 42 that is illustrated in FIG. 3 is preferably designed to occupy 2 RMUs along the height of a rack 20, while the combination of two large side cable guides 41 that is illustrated in FIG. 4 is preferably designed to occupy 3 RMUs along the height of a rack 20, and the combination of two small side cable guides 42 that is illustrated in FIG. 5 is preferably designed to occupy 1 RMU along the height of a rack 20.
In at least one embodiment, the T-shaped projections 63,64 are integrally formed with the horizontal support member 46 and posts using an injection molding process. In at least some aspects of the present invention, however, the side cable guides 42 may be constructed according to the teachings of commonly-assigned U.S. patent application Ser. No. 12/350,216 to Garza et al., which published as U.S. Patent Application Publication No. US 2009/0236117 A1, the entirety of which is expressly incorporated by reference herein.
Referring again to FIG. 3, it will be appreciated that some of the T-shaped projections 63 include door attachment hinge bosses 76 disposed at the ends thereof. FIGS. 6 and 7 are a fragmentary isometric view and a fragmentary side view, respectively, of one of the hinge bosses 76. Each hinge boss 76 includes an inner semi-cylindrical surface 92 and an outer semi-cylindrical barrel 94 formed by a series of ridges 95. An indexing groove 96 is arranged near the ends of the ridges 95. The hinge boss may be molded with the rest of the projections 63 and side cable guides 41,42.
FIG. 8 is an end view of the door 38 of FIG. 2. As shown therein, the door 38 includes hinge structures 75 along both longitudinal edges. The hinge structure 75 includes two arms 77,78, defining a hinge channel 79, that may be snapped around the hinge bosses 76. The outer arm 77 includes an indexing stop 97, while the inner arm 78 includes a semi-cylindrical pivot 98 adapted to be received in the inner semi-cylindrical surface 92 of the hinge boss 76.
The door 38 is mounted on the side cable guides 41,42 by snapping the hinge structure 75 onto the hinge bosses 76. FIG. 9 is an end view of the horizontal cable manager 30 of FIG. 2, showing the door 38 installed on both the upper and lower hinge bosses 76 of the trough 32. The door 38 may then be opened along either its upper or lower edge or removed altogether. FIGS. 10 and 11 are end views of the horizontal cable manager 30 of FIG. 9, showing the door 38 being opened along its lower edge and rotated upward about the upper hinge bosses 76 of the trough 32. As illustrated therein, the hinge boss 76 is disposed in the hinge channel 79 defined between the hinge structure arms 77,78. The semi-cylindrical pivot 98 rotates along the semi-cylindrical surface 92 of the hinge boss 76, and the outer arm 77, which is also semi-cylindrical, rotates along the semi-cylindrical barrel 94 of the hinge boss 76. As the door 38 is rotated to the position shown in FIG. 5, it will be appreciated that the indexing stop 97 reaches the groove 96 on the hinge boss 76. When it does so, it snaps into place in the groove 96, thereby holding the door 38 in place in that position. The force required to rotate the door 38 out of that position is intended to be relatively minimal such that a user may manipulate the door 38 easily to remain open or to be closed, as desired. FIG. 12 is an isometric view of the horizontal cable manager 30 of FIG. 11, showing the door 38 in a fully open and stationary position.
With reference to FIGS. 10 and 11, it will be appreciated that the concentric nature of the various elements of the hinge boss 76 and hinge structure 95 results in rotation of the door 38 within a limited space. In particular, during its rotation the door 38 moves entirely within the footprint of the cable manager 30, illustrated by line 100. This is particularly advantageous in installations in which equipment and accessories are mounted close together on a rack 20 or the like in that operation of the door 38 of one cable manager 30 does not interfere with other equipment or accessories. This is more fully illustrated in FIGS. 13 and 14, which are end views of the two horizontal cable managers 30 of FIG. 1 with their doors in various states. In FIG. 13, the upper door 38 is closed, and the lower door is being opened without interfering with, or being interfered by, the upper door 38. In FIG. 13, both doors 38 are open and in their stationary position without interfering with each other. Other configurations are likewise possible.
The cable managers described above are “single-sided” cable managers in that they include T-shaped and L-shaped projections 63,64 extending only in one direction, and thus comprise only one horizontal cable trough for routing cables on either the front or back of the rack 20. However, the same principles may likewise be applied to create a “double-sided” horizontal cable manager (not shown) that is similar to the single-sided version but with projections 63,64 extending both forwardly and rearwardly from horizontal support members and include doors on each side.
Furthermore, as described herein, the invention is disclosed in a horizontal orientation. However, it will be appreciated that all or part of the invention as described herein may be implemented in a vertical orientation. For example, it is contemplated that the cable manager as described herein may be implemented for use in a vertical orientation.
Based on the foregoing information, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application.
