Definitions
- the present invention relates to systems and methods for the management and routing of telecommunication cables, and, more particularly, to covers for cable trough members.
- optical fiber cable management requires industry attention.
- One area of optical fiber management that is necessary is the routing of optical fibers from one piece of equipment to another.
- optical fiber cables may be routed between fiber distribution equipment and optical line terminating equipment.
- the cable routing can take place in concealed ceiling areas or in any other manner to route cables from one location to another.
- such routing systems include a plurality of components, such as trough members and couplers, for defining the cable routing paths.
- the trough members are joined together by couplings.
- U.S. Patent Nos. 5,067,678; 5,316,243; and 5,752,781 teach cable routing systems that include a plurality of trough members and couplers.
- trough members are typically U-shaped and therefore have open tops through which debris and other undesirable material, such as tools, hardware, and other debris, can fall onto the fibers rurining through the trough members.
- the trough members include covers to close the open tops, it may be necessary to periodically gain access to the interior portions of the trough members to, for example, add or remove fibers. It is therefore desirable to provide covers for trough members that reduce debris from entering interior portions of the trough members while still allowing for access to the interior portions of the trough members.
- a system includes at least one hinge clip coupled to a trough member to allow the trough member to pivot from an open position to a closed position.
- a capture clip can also be provided on the trough member to hold the cover in the closed position.
- a system includes two cover portions, which are each coupled to opposite sidewalls of a trough member by hinge clips.
- Each cover portion can extend partially across an open portion of the trough member, and the cover portions, in the closed position, can define therebetween a slot.
- a hinge clip includes first and second structures for limiting the amount of rotation of the cover beyond the open and closed positions.
- One embodiment of a capture clip includes a seat for capturing a portion of the cover when the cover is in the closed position.
- One embodiment of a cover includes a pivot member and a capture member. In example embodiments, the capture member defines an elbow to be received in the seat of the capture clip.

- Embodiments of the present invention are directed to covers for cable trough members.
- the covers can be coupled to the trough members to cover the trough members.
- the covers can be pivoted with respect to the trough members to provide access to the interior portions of the trough members.
- the term trough member is used to refer to any trough, fitting, railway, raceway, or similarly configured component including any number of ends. Referring now to Figures 1-5, an example embodiment of a cable trough system 100 is shown.
- the system 100 generally includes a trough member 110, a hinge clip 130, a capture clip 150, and a cover 170.
- the clips 130 and 150 can be coupled to the trough member 110 to hold the cover 170, and the hinge clip 130 can allow the cover 170 to pivot relative to trough member 110 between closed and open positions.
- the cover 170 is illustrated in the closed position in Figures 1-3 and in the open position in Figures 4 and 5.
- the example trough member 110 includes first and second sidewalls 112 and 116 coupled to a bottom wall 114 generally forming a trough with an interior space 118 through which cables such as fiber (e.g., fiber cables 101 shown in Figure 1) can be run.
- the trough member 110 also includes lips 310 and 311 creating a first slot 113 and lips 312 and 313 creating a second slot 117 positioned on the first and second sidewalls 112 and 116, respectively.
- the lips 310, 311 and 312, 313 and first and second slots 113 and 117 created thereby can be used to allow components to be attached to the trough member 110, as described further below.
- the trough member 110 extends lengthwise from a first end 120 to a second end (not shown).
- the trough member 110 can be of varying lengths and widths, and can be coupled to other trough members or similar structures to form a cable trough system.
- the example hinge clip 130 shown in more detail in Figures 2, 5, and 6-8, includes first and second members 133 and 134 creating a channel 131 to receive the lip 310, and a clip portion 132 extends partially into the first slot 113 to couple the hinge clip 130 to the first sidewall 112 of the trough member 110.
- the hinge clip 130 further includes a hinge portion 135 having first and second arms 136 and 137 creating a socket 138.
- the hinge clip 130 can be coupled to the trough member 110 as shown in Figures 1, 2, 4, and 5, so that the channel 131 receives the lip 310, and the clip portion 132 extends partially into the slot 113.
- the hinge clip 130 is coupled to the sidewall 112 by snapping the hinge clip 130 onto a mid-portion of the trough member 110. This can be accomplished by positioning the channel 131 adjacent to the end of the sidewall 112, and applying a downward force on the hinge clip 130 to cause the first member 133 to bow out slightly with respect to the second member 134 to allow the lip 310 to be received in the channel 131 and to allow the clip portion 132 to extend partially into the slot 113.
- the hinge clip 130 can be configured to be coupled to the sidewall 112 by sliding the hinge clip 130 onto an end, such as first end 120 of the trough member 110, and into the desired position on the trough member 110.
- hinge clip 130 is configured to be slid onto the trough member 110
- additional structure can be provided for fixing the hinge clip 130 in a desired position on the trough member 110 such as, for example, screws or bolts, as described further below.
- the hinge clip 130 can be removed from the trough member 110 similarly, either by forcing the clip portion 132 out of the slot 113 and then removing the hinge clip 130 from the trough member 110, or, alternatively, by sliding the hinge clip 130 off an end of the trough member 110.
- the hinge clip 130 extends from a first end 140 to a second end 142. In preferred embodiments, the length of the hinge clip 130 (i.e., the distance between ends 140 and 142) is between 1 and 5 inches.
- the hinge clip 130 is preferably molded from a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile-butadiene-styrene(ABS)/polycarbonate blend.
- a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile-butadiene-styrene(ABS)/polycarbonate blend.
- ABS acrylonitrile-butadiene-styrene
- the hinge clip 130 is injection molded and varies in thickness from one end to the other to allow the molded clip to be stripped from the mold. Other manufacturing methods and materials can also be used.
- the example capture clip 150 shown in more detail in Figures 3, 9, and 10, includes first and second members 153 and 154, creating a channel 151 to receive the lip 312, and a clip portion 152 extending partially with the slot 117 to couple the hinge clip 150 to the second sidewall 116 of the trough member 110.
- the hinge clip 150 further includes a ramp portion 155 and a seat 156, as described further below.
- the capture clip 150 can be coupled to the trough member 110, as shown in Figures 1 and 3, in a manner similar to that described above with respect to the hinge clip 130.
- the capture clip 150 can be coupled to the sidewall 116 by snapping the capture clip 150 onto the sidewall 116 so that the channel 151 receives the lip 312, and the clip portion 152 extends partially into the slot 117.
- the capture clip 150 can be configured to be slid onto an end, such as first end 120, and into the desired position on the trough member 110.
- the capture clip 150 can be removed from the trough member 110 similarly, either by forcing the clip portion 152 out of the slot 117 and then removing the capture clip 150 from the trough member 110, or, alternatively, by sliding the capture clip 150 off an end of the trough member 110.
- the capture clip 150 extends from a first end 160 to a second end 162.
- the length of the capture clip 150 (i.e., the distance between ends 160 and 162) is between 1 and 5 inches. In a preferred embodiment, the length is approximately 1.75 inches.
- the capture clip 150 is preferably molded from a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile-butadiene-styrene(ABS)/polycarbonate blend. In a preferred embodiment, the capture clip 150 is injection molded and varies in thickness from one end to the other to allow the molded clip to be stripped from the mold. Other manufacturing methods and materials can also be used.
- the example cover 170 shown in more detail in Figures 2, 3, 5, and 11-13, includes a main body 172 having first and second ends 174 and 176.
- the ends 174 and 176 are preferably, but need not be, angled with respect to the main body 172.
- the cover 170 includes pivot members 178 and 179 at each of the first and second ends 174 and 176.
- Each pivot member 178 and 179 can, for example, be in the form of cylindrical bead, rod, shaft, or other similar shape including a generally round outer circumference.
- Grooves 173 and 175 with ends 177 are formed generally between the ends 174 and 176 and the outer circumference of the pivot members 178 and 179.
- the cover 170 extends from the first sidewall 112 to the second sidewall 116 to cover the open top of the trough member 110. Depending on the width of the trough member 110, a width of the cover 170 between ends 174 and
- the width of cover 170 is 4, 6, or 12 inches, depending on the width of the trough member.
- the cover 170 extends lengthwise from a first end 180 to a second end 182.
- the length of the cover 170 i.e., the distance between ends 180 and 182 is between 2 and 8 feet. In a preferred embodiment, the length is approximately 6 feet.
- Successive covers 170 can be used end to end to cover trough members of longer length, and a cover 170 can be cut to other desired lengths.
- the cover 170 is preferably extruded from a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile- butadiene-styrene(ABS)/polycarbonate blend, although other manufacturing methods (e.g., molding) and materials can also be used.
- a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile- butadiene-styrene(ABS)/polycarbonate blend, although other manufacturing methods (e.g., molding) and materials can also be used.
- ABS acrylonitrile- butadiene-styrene
- the cover 170 is illustrated in the closed position. In this position, pivot member 178 of the cover 170 is positioned in the socket 138 of the hinge clip 130. In addition, pivot member 179 of the cover 170 is positioned in the seat 156 of the capture clip 150.
- the cover 170 extends over the open top of the trough member 110 and thereby protects any components (e.g., fiber cables) positioned in the interior space 118 of the trough member 110 from any debris dropped on the cover 170.
- the cover 170 can be pivoted from the closed position to the open position. This can be accomplished by applying force in a direction A on the second end 176 of the cover 170, which causes the pivot member 179 to be released from the seat 156 of the capture clip 150.
- the cover 170 can then be pivoted about the pivot member 178 in the socket 138 of the hinge clip 130 in the direction A to the open position shown in Figures 4 and 5. Referring again to Figures 4 and 5, in the open position, the first arm
- the cover 170 is prevented from pivoting further in the direction A, thereby maintaining the cover 170 in the open position and the pivot member 178 in the socket 138.
- the cover 170 can also be pivoted once again in a direction B back to the closed position.
- the pivot member 179 contacts and rides along the ramp 155 of the capture clip 150, which directs the pivot member 179 into the seat 156.
- sidewall 116 that is coupled to the capture clip 150 bows inward slightly, allowing the pivot member 179 to clear the ramp 155 and drop into the seat 156.
- FIG. 1 An example method of assembling the trough system 100 is as follows. Initially, the hinge clip 130 and the capture clip 150 are positioned on the trough member 110. This can be accomplished, as described above, preferably by snapping the hinge clip 130 and capture clip 150 onto the trough member 110 at the desired locations.
- the clips 130 and 150 can be slid slightly with respect to the trough member 110 to further position the clips 130 and 150 as desired on the trough member 110.
- multiple hinge clips 130 and capture clips 150 are used.
- the hinge clips 130 and capture clips 150 are spaced at between approximately 1 and 3 feet intervals, more preferably at approximately 2 feet intervals.
- Each hinge clip 130 can be positioned across from each capture clip 150 (as shown in the example of Figures 21-23), or the clips can be staggered as desired.
- the cover 170 can be placed over the open top of the trough member 110, and the cover 170 can be pressed downward toward the trough member 110 to snap the pivot member 178 into the sockets 138 of the hinge clips 130 and the pivot member 179 into the seats 156 of the capture clips 150.
- the cover 170 Once the cover 170 is coupled to the trough member 110, the cover 170 can be pivoted between the closed and open positions as described above. Referring now to Figures 14-20, another example embodiment of a trough system 200 is shown.
- the system 200 including hinge clip 130, is similar to the system 100, with the differences noted below.
- a split cover including cover portions 272 and 274 is provided.
- cover portions 272 and 274 each extend partially across the open top of the trough member 110.
- ends 276 of the cover portions 272 and 274 extend closed to one another, preferably a slot 230 is formed between ends 276, as described further below.
- a pivot member 279 (similar to pivot members 178 and 179) is positioned at an end 290 of the cover portion 274.
- a first groove 294 with end 275 is formed between an outer circumference of the pivot member 279 and the end 290 (similar to groove 173), and a second groove 296 with end 277 is formed between the pivot member 279 and a member 292.
- the end 276 of the cover portion 274 can be formed with a rounded surface (see Figures 14, 16, and 18-20) to minimize any sharp edges. This can be advantageous, for example, to minimize any wear on fiber cables if the cables are run through the slot 230 with the cover portions 272 and 274 in the closed position.
- the pivot member 279 of the cover portion 274 can be received in the socket 138 of the hinge clip 130.
- the second arm 137 of the socket 138 contacts end 277 of the groove 296 to define the closed position.
- the cover portion 274 can be pivoted into the open position by applying force to the end 276 in the direction A.
- the first arm 136 of the socket 138 contacts end 275 of the groove 294 to define the open position and prevent the cover portion 274 from being pivoted further in the direction A.
- the cover portion 274 can be pivoted back to the closed position by applying a force to pivot the cover portion 274 in the direction B.
- the cover portion 274 can be pivoted in the direction B, as described above, until the second arm 137 of the socket 138 contacts end 277 of the groove 296 in the closed position.
- the cover portion 272 is preferably configured as a mirror image of the cover portion 274 and functions in a similar manner. As shown, no capture clip 150 is used for system 200. Instead, an additional hinge clip 130 is provided to hold the pivot member of the cover portion 272.
- the slot 230 between cover portions 272 and 274 is less than 1 inch, more preferably 0.75 inch, and even more preferably approximately 0.5 inch or less. In this configuration, the slot 230 allows limited access to the interior space 118 of the trough member 110 without requiring that any covers be opened or removed. For example, additional fibers can be introduced into the interior space 118 of the trough member 110 by insertion through the slot 230 without requiring that either cover portions 272 or 274 be opened. However, the slot 230 is preferably small enough to prevent most material from entering the interior space 118 of the frough member 110 when cover portions 272 and 274 are in the closed positions.
- An example method of assembling the system 200 is as follows.
- the hinge clips 130 are positioned on the trough member 110 in a manner as described above. Then, the pivot members 279 of each of the cover portions 272 and 274 are inserted into the sockets 138 of the hinge clips 130 to couple the cover portions 272 and 274 to the trough member 110. Each cover portion 272 and 274 can be opened and closed separately or in unison as described above.
- the example cable frough systems 100 and 200 can exhibit a variety of advantages.
- the hinge and capture clips can be coupled to existing frough members to allow pivoting covers to be added the trough members.
- the hinge and capture clips are preferably configured to snap onto the trough member without requiring the clips to be slid onto the trough member, and without requiring additional hardware such as screws or bolts to hold the clips in place on the trough member.
- additional hardware can be used to, for example, lock the hinge and capture clips in place on the trough member.
- the hinge and/or capture clips can be formed as an integral part of the trough member.
- the cover is preferably configured to be easily snapped onto the hinge and capture clips without requiring the cover to be slid through the clips. This can be advantageous so that the cover can be easily coupled to the trough member.
- the systems 100 and 200 described above can also be advantageous in that they can be configured to meet a variety of standards associated with cable trough systems.
- the hinge and capture clips can be configured to hold the covers disclosed herein in close proximity to upper ends of the sidewalls of the trough member such that a 0.125 inch probe cannot be inserted into the interior space of the trough member, as required by UL Specification 60950, Safety of Information Technology Equipment.
- the slot formed between the cover portions of system 200 can be sized to allow access to the interior space of the frough member while preventing most debris from entering.
- a slot of approximately 0.5 inch between cover portions can prevent the handle of a typically-sized screw driver from entering the interior space of the trough member when dropped on the closed cover portions, while still allowing fiber cables to be run into the interior space without requiring the covers to be opened.
- the systems 100 and 200 can be advantageous in that the covers can be snapped or propped in the closed position and propped into the open position without requiring additional components beyond the hinge clips (and preferably capture clips for system 100) to be added to either the sidewalls or interior space of the trough member.
- the hinge clip 300 includes first and second members 333, 334, creating a channel 331 to receive the sidewall 112 of the trough member 110.
- the hinge clip 300 includes first and second arms 336, 337 creating a socket 338.
- the channel 331 mounts the hinge clip 300 to the sidewall 112 of the frough member 110.
- the socket 338 mounts the cover portion 272 to the hinge clip 300.
- the functions of the channel 331 and the socket 338 are the same as the channel 131 and the socket 138 for the hinge clip 130 noted above.
- Adjacent to the first arm 336 is a first landing 376 for use in limiting rotation of the cover portion 272 beyond the fully open position.
- Adjacent to the second arm 337 is a second landing 378 for use in limiting rotation of the cover portion 272 beyond the closed position.
- the end 290 of the cover portion 272 defines a projection with an end 301 which engages the first landing 376 to limit the amount of opening of the cover portion 272.
- the member 292 on the cover portion 272 has an end 303 which engages the second landing 378 to limit the amount of closing of the cover portion 272.
- the ends 348, 349 of the first and second arms 336, 337 are received in similar grooves 294, 296 in the cover portion 272 as for the hinge clip 130.
- the hinge clip 300 further includes a third arm 342 which creates a spacing 343 between the third arm 342 and the second arm 337.
- the spacing 343 receives the member 292 of the cover portion 272.
- the spacing 343 captures the member 292 when the cover portion 272 is closed.
- the spacing 343 and the member 292 are curved.
- the third arm 342 helps prevent the pivot member 279 from lifting out of the socket 338, such as may tend to occur for larger or heavier cover portions 272 when the cover portion is in the closed position.
- the trough system 450 includes trough member 110, a hinge clip 400, a capture clip 500, and a cover 474.
- the hinge clip 400 (see Figures 34 and 36) can be configured in a manner similar to any of the hinge clips described herein, such as hinge clips 130 and 300 described above, hi the example illustrated, hinge clip 400 is similar to hinge clip 300.
- the example capture clip 500 is similar in design to capture clip 150 described above.
- Capture clip 500 includes first and second members 553 and 554, creating a channel 551, and a clip portion 552 extending partially within the slot 117 of trough member 110 to couple the hinge clip 500 to the first sidewall 112 of trough member 110.
- the hinge clip 500 further includes a projecting portion 605 and a ramp portion 555 extending at an angle with respect to the projecting portion 605.
- a space between the second member 553 and the projecting portion 605 creates a seat 556, as described further below.
- the capture clip 500 can be coupled to the frough member 110, as shown in Figures 34 through 37, in a manner similar to that described above with respect to the capture clip 150.
- the capture clip 500 can be coupled to the sidewall 112 by snapping the capture clip 500 onto the sidewall 112 so that the channel 551 receives the lip 312 of sidewall 112, and the clip portion 552 extends partially into the slot 117.
- the capture clip 500 can be configured to be slid onto an end of the trough member 110.
- the capture clip 500 can be removed from the frough member 110 similarly, either by forcing the clip portion 552 out of the slot 117 and then removing the capture clip 500 from the trough member 110, or, alternatively, by sliding the capture clip 500 off an end of the trough member 110.
- the capture clip 500 extends longitudinally between 1 and 5 inches. In a preferred embodiment, the length is approximately 1.75 inches.
- the capture clip 500 is preferably molded from a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile- butadiene-styrene(ABS)/polycarbonate blend.
- the capture clip 500 is injection molded and varies in thickness from one end to the other to allow the molded clip to be stripped from the mold. Other manufacturing methods and materials can also be used.
- cover 474 is described in greater detail. Cover 474 is similar to cover 170 described above, except that cover 474 is asymmetric about its longitudinal axis.
- the example cover 474 has first and second ends 574 and 576.
- the ends 574 and 576 are preferably, but need not be, angled with respect to a main body 572 of the cover 474.
- the cover 474 includes a pivot member 479 positioned at the first end 574.
- the pivot member 479 can, for example, be in the form of cylindrical bead, rod, shaft, or other similar shape including a generally round outer circumference.
- Groove 573 with end 575 is formed generally between the end 574 and the outer circumference of the pivot member 479.
- a capture member 610 is formed at opposite end 576 of the cover 474.
- capture member 610 includes first and second members 612 and 614 attached at elbow 613.
- the main body 572 and first member 612 form a concave portion
- the first and second members 612 and 614 form a convex portion creating elbow 613.
- the elbow 613 of capture member 610 is configured to ride along ramp portion 555 and is received in seat 556 of capture clip 500 upon pivoting of the cover 474 from an open to a closed position.
- the end 576 projects slightly from the main body 572 of the cover 474 to act as a handle so that a user can grasp the end 576 and pivot the cover 474 from the open and closed positions.
- the example cover 474 extends from the first sidewall 112 to the second sidewall 116 to cover the open top of the frough member 110. See Figures 34 and 37.
- the width of cover 474 is 4, 6, or 12 inches, depending on the width of the trough member.
- the cover 474 extends lengthwise from a first end 580 to a second end 582.
- the longitudinal length of the cover 474 i.e., the distance between ends 580 and 582
- the length is approximately 6 feet.
- the cover 474 is preferably extruded from a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile-butadiene- styrene(ABS)/polycarbonate blend, although other manufacturing methods (e.g., molding) and materials can also be used.
- a plastic material such as, for example, a synthetic thermoplastic polymer such as an acrylonitrile-butadiene- styrene(ABS)/polycarbonate blend, although other manufacturing methods (e.g., molding) and materials can also be used.
