Description

FLEXIBLE CABLE MANAGEMENT SYSTEM

BACKGROUND OF THE INVENTION:

1. Field of the Invention: The present disclosure relates to cable management systems and more particularly to flexible cable management systems for cable management and

installation applications.

2. Description of related art:

Currently available cable management systems require the procurement

and installation of turning components and transitions. The presently disclosed flexible cable management system is designed to allow for either lateral or vertical curves thus eliminating the need for turning components and transitions. BRIEF SUMMARY OF THE INVENTION:

The presently disclosed cable management system is designed to allow

for the installation, organization, routing and protection of cable. It is designed in such a way as to bend into curves in either lateral or vertical directions without tools, heat, fixtures or chemical alterations and as such is different from any other product. It

therefore eliminates the need to procure and to install turning components and

transitions. The design of the presently disclosed cable management system with

multiple fastener points, allows for single person installation. This will create significant savings in person hours for the design and installation of the invention in user installations.

Equally spaced spoke design and integrated proprietary enter/exit

components allow the cable to leave the presently disclosed flexible cable management system at any point and in any direction to reach its destination. The enter/exit components are designed in such a way as to prevent copper or fiber optic cable from

kinking or bending in too tight of a radius which would have a negative effect on the performance of the cables signals. BRIEF DESCRIPTION OF THE DRAWINGS:

Referring to the drawings in detail, and initially to FIG. 1, the presently

disclosed flexible cable management system 100 is shown having both lateral and vertical bends formed therein. Such bends can be formed without the use of tools or

other devices. Multiple fastener points 3 allow the flexible cable management system 100 to be secured in whatever position it has been bent, by means of a washered

fastener 7 to a concrete surface 10 or a wall board anchor 9 to a wall board surface 11. A plurality of cables 13 are installed within the flexible cable management system and are capable of being secured to any of a plurality of cable support members such as spokes 5 with a standard cable fastener 14. Sections of flexible cable management

system 100 can be joined together at a connector tail 1.

Referring now to FIGS. 2A, 2B and 2C, an enter/exit component 2 is illustrated in the three views. The enter/exit component 2 is indexed to the flexible

cable management system 100 by means of a spoke index and secured by wire ties

passed through attachment holes 4. A cable may be secured to enter/exit component 2

by means of wire ties passed through wire tie attachment holes 12 and further held in place by means of cable containment tabs 15. A cable radius 17 is formed in enter/exit component 2 to preclude the installed cable from bending too tightly or kinking.

In FIGS. 3 A, 3B and 3C, a flexible spine 6, spokes 5 and enter/exit component 2 are shown in their assembled positions.

Referring now to FIGS. 4A, 4B and 4C, various means for attaching the

flexible cable management system 100 are illustrated. In FIG. 4A, flexible cable

5 management system 100 is shown anchored to a concrete surface 10 at fastening point 3 by means of washered fastener 7. In FIG. 4B, flexible cable management system 100 is anchored to a wall board 11 at a fastener point 3 by means of a wall board fastener

9. Two support sections are shown joined together at connector tails 1 by means of a

standard clamp 8, in FIG. 4C. o The flexible cable management system 100 includes a series of formed

wire spokes 5 welded to a single spine 6. The wire spokes 5 are formed in a fashion to allow the maneuvering and protection of the cables 13 that are installed in the system. Having a single spine allows the flexible cable management system 100 to be bent by

hand in any direction necessary. Each spoke 5 has two fastener points 3 which allow the flexible cable management system 100 to be secured to the installation surface at multiple points along its length. Preformed proprietary enter/exit components 2 attach to spokes 5 of the flexible cable management system 100 at any point allowing the

cable 13 to exit the flexible cable management system 100 without the risk of damage due to kinking. Flexible cable management system 100 is designed in such a way that it can be installed beneath raised floor, on existing floors, on walls and risers or

suspended from a ceiling. During installation, the technician will lay out the path of the cable runs on the primary floor of an installation area between the stantions of the raised floor.

The technician would then place eight foot sections of the flexible cable management

system 100 on the layout lines, bending by hand where necessary either laterally, up a wall or down a riser. Then, using a standard power charged stud gun and washered fasteners, randomly secure the flexible cable management system 100 to the installation area floor by means of the built in fastener rings. Anti-kink enter/exit components 2

would be installed on spokes 5 of the flexible cable management system 100 where it is necessary for cables 13 to exit the system to reach their destination. After the network of flexible cable management system 100 is completed, the technician would place

copper and/or fiber optic cable into flexible cable management system 100 and

randomly secure it using cable ties, to spokes 5 of flexible cable management system 100. Flexible cable management system 100 allows cable to be organized, routed and protected against crushing or kinking.

Referring to FIGS. 5 and 6, an alternative embodiment of the cable

management system of the present disclosure is shown generally as flexible cable tray 200. Many of the overall characteristics of cable management system 100 are also featured in cable tray 200. Accordingly, the following description will focus mainly on

the unique structural and functional aspects of cable tray 200. It is within the scope of the present disclosure, however, that the assembly, connection and fastening features

described above in connection with cable management system 100 may apply to cable tray 200 as well.

Cable tray 200 is particularly suited for use in installations wherein it is desirable or even necessary to route cable bundles overhead. The prior practice in some installations of simply laying cable on the top of suspended ceiling gridwork now

violates electrical code requirements for many locations. Further, cabling such as fiber

optic or copper data transmission cable is subject to signal attenuation due to damage, no matter how slight, which may often be the result of the cable being haphazardly

positioned along the top of ceiling grid structure and thus exposed to such damage. Cable tray 200 provides a novel way of suspending cable bundles from the framework

of the building structure itself, for example by bracketing the tray to studs or the like. Similar to cable management system 100, cable tray 200 is preferably

constructed of wire stock and includes a flexible spine 206 which runs centrally along

the length of cable tray 200. This configuration provides the maximum flexibility for cable tray 200 and, therefore maximum versatility during installation. A dual opening

cable support member 205 is formed by bending the wire stock to form cable receiving portions 220 and 222 disposed one on either side of central spine 206. The two receiving portions may be defined by a single piece of wire stock which is bent to form

5 a web section 224. Central spine 206 may be attached to web portion 224 either

transversely along the top thereof, as shown in FIG. 5, or the bottom thereof, by any suitable known methods, for example, welding.

The central location of spine 206 facilitates the self balancing feature of

cable tray 200. In particular, once cable tray 200 is installed, cable is preferably

0 loaded evenly into each of receiving portions 220 and 222 to effectuate a balanced load

in cable tray 200. Looped ends 226 and 228 are provided on cable support 205 to reduce the likelihood of inadvertent damage due to contact of cables with rough edges during installation.

As shown in phantom lines in FIG. 6, cable tray 200 may be flexed

5 significantly to either side, to effectuate at least about a 90 degree or even greater turn of cable tray 200 without individual cable support sections 205 making contact with

each other. Similarly, cable tray 200 may transition from a horizontal run to a vertical run.

Referring to FIGS. 7 and 8, a further alternative embodiment

o constructed in accordance with the present disclosure is shown generally as cable tray 300. Cable tray 300 features partially enclosed cable receiving portion 320. Spine 306

is attached to cable support members 305 transversely along a top segment thereof in similar manner as set forth above for cable tray 200 and cable management system 100. Spine 306 is attached to cable supports 305 substantially directly over the center of

gravity of the unit as a whole. In this manner, when cable tray 300 is loaded with cable evenly within receiving portion 320, there will not be any undesirable torque 5 applied to spine 306 which is preferably attached to the building structure by suitable

brackets or the like. End portions 326 and 328 are formed to bend away from the

opening into receiving portion 320 to minimize the chance of even the slightest amount of damage to the cabling being placed in the receiving portion 320.

Although the illustrative embodiments of the present disclosure have l o been described herein with reference to the accompanying drawings, it is to be

understood that the disclosure is not limited to those precise embodiments, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the disclosure. All such changes and modifications are intended to be included within the scope of the disclosure as defined

15 by the appended claims.
