Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to raised floor systems and,
more particularly, to a cable support assembly for use in
connection with a raised floor system.
[0003] 2. Background of Related Art
[0004] Raised floor systems have been developed to provide the
additional utility space needed in various different conduit or
cable intensive environments where the original construction did
not provide adequate means of accommodating the vast amount of
conduit or cable. For example, probably the most common environment
requiring vast amounts of additional protected space is for large
computing systems. Such installations were typically made in
facilities which simply were not designed to accommodate the vast
amount of cable runs required to operate the typical large computer
system. Other applications where additional utility space is
required include mechanical systems, e.g., heating, ventilating and
air conditioning systems.
[0005] A common problem experienced in utilizing raised floor
systems is maintaining organization of the various cables,
conduits, pipes, etc. which are routed beneath the floor system.
One solution to this problem is to provide a cable tray system
beneath the floor panels of the raised floor to contain and direct
cables along their respective pathways. An example of such a cable
tray system is disclosed in U.S. Pat. No. 4,596,095 which issued on
Jun. 24, 1986 to Chalfant (the "'095 Chalfant Patent"). The '095
Chalfant Patent features a modular cable tray assembly which is
formed from modular sections which include a number of different
components all of which must be separately assembled to form the
cable tray. For example, the cable tray includes separate straight
sections, horizontal bend sections, horizontal tee sections,
horizontal cross-intersection sections, as well as splice plates to
connect the various components to each other as well as supporting
the assembled cable tray above the building floor. Such a cable
tray assembly is, therefore, independent of the raised floor
system.
[0006] One drawback of such a raised floor and cable support system
is the additional labor required to assemble the various components
of the separate raised floor and cable support systems. In
geographic regions with particularly high labor rates, the cost of
erecting such a labor intensive dual system could prove to be cost
prohibitive.
[0007] Another drawback of such a system is that the amount of
space required by the structural supporting components of the two
separate systems leaves less space available for carrying and
organizing larger numbers of cable runs.
[0008] Yet another drawback of installing independent raised floor
and cable support systems is the cost of procuring the materials
required for two separate support structures. These additional
labor and material costs can significantly increase the overall
cost of installing a complete system.
[0009] An alternative solution to supporting cable runs below a
raised floor assembly is proposed in U.S. Pat. No. 5,548,932 which
issued on Aug. 27, 1996 to Mead (the "'932 Mead Patent"). The '932
Mead Patent features a height adjustable cable tray support system
which includes a number of separate components which must be
assembled to form the cable support system. Plates which support
the cable tray are secured by welding or other methods to the
pedestals of the existing raised floor system featured in the '932
Mead Patent. Additionally, support rods are required in the '932
Mead Patent cable tray support system, which support the cable tray
on the support plates.
[0010] One disadvantage of such a system is the labor intensive
nature of the installation. In particular, each support plate must
be separately secured to the floor system pedestals and the support
rods and cable tray sections must be installed. This combined with
the cost of the material components required for such a system can
add significant cost to the installation of the complete
system.
[0011] Accordingly, there is a continuing need for improved raised
floor and cable management systems which require a fewer number of
components. A need also exists for raised floor and cable
management systems which are easier to install than existing
systems and which provide increased storage capacity and
accessibility.
SUMMARY
[0012] The present disclosure provides a raised floor system which
overcomes the above-noted and other disadvantages of existing
raised floor and cable management systems. Additionally, the
present disclosure provides a raised floor system which requires
many fewer components to assemble thereby resulting in greatly
reduced material and labor costs to install a complete raised floor
and cable management system or to upgrade an existing raised floor
system with the presently disclosed cable support assembly.
[0013] In one aspect of the present disclosure a raised floor
system is provided which includes at least one cable support
apparatus. The cable support apparatus including first and second

and second stringer elements. Each of the stringer elements is
preferably adapted for removable engagement with at least one of
the support pedestals of the raised floor system. The channel
section preferably includes at least one engagement member
extending longitudinally therefrom. The engagement member is
configured and dimensioned to engage a portion of an adjacent cable
support apparatus in the raised floor system. Preferably, the
channel section includes a plurality of transverse support members
extending from the first stringer element to the second stringer
element.
[0014] In one aspect of the disclosure, each engagement member is a
down turned hook member. Preferably, each down turned hook member
extends longitudinally from an end-most transverse support
member.
[0015] Preferably, at least one end of each of the first and second
stringer elements is bifurcated to thereby define a notch therein.
The notch is configured and dimensioned to surround a portion of a

stock.
[0017] It is contemplated that at least one stringer element
includes a locking mechanism adapted to secure the cable support
apparatus to at least one of the plurality of support pedestals. In
one embodiment, the locking mechanism includes a cross-bar
extending across the width of the notch. A first end of the
cross-bar is pivotally coupled to one side of the bifurcated
stringer and a second end of the cross-bar is configured and
adapted to engage another side of the bifurcated stringer via a
snap-fit type engagement.
[0018] In an alternative embodiment, the ends of each stringer
include a leg extending longitudinally from a side thereof and an
L-shaped locking bracket having a first leg pivotally coupled to
another side of the end of each stringer and a second transverse
leg configured and adapted to engage the leg extending from the
stringer via a snap-fit type engagement.
[0019] It is further contemplated that each stringer is provided
with a series of apertures formed along the length thereof. Each
aperture is configured and dimensioned to engage a support
pedestal. Preferably, each pedestal engages a selected aperture in
a bayonet type coupling. It is contemplated that each aperture
extends into a side portion of the stingers and terminate in a
substantially circular opening. Accordingly, the cable support
apparatus can depend from the plurality of support pedestals.
[0020] In another aspect of the disclosure, one end of the cable
support apparatus is configured and dimensioned to be supported on
at least one support pedestal and the other end of the cable
support apparatus is supported, via the engagement member, by an
adjacent cable support apparatus. Preferably, at least one end of
each of the first and the second stringer elements is bifurcated
defining a notch therein. Each notch is configured and dimensioned
to surround a portion of a respective support pedestal.
[0021] In another aspect of the present disclosure a cable support
apparatus is provided for use with a raised floor system including
a plurality of support pedestals and floor panels. The raised floor
system includes a plurality of cable support apparatus each of
which includes first and second stringer elements with each of the
stringer elements being adapted for removable engagement with at
least one of the support pedestals of the raised floor system. The
cable support apparatus further includes a channel section
suspended from the first and second stringer elements and at least
one engagement member extending longitudinally from one end
thereof. The engagement member is configured and dimensioned to
engage a portion of an adjacent cable support apparatus in the
raised floor system. Preferably, the channel section includes a
plurality of transverse support members extending from the first
stringer element to the second stringer element.
[0022] Preferably, at least one end of each of the first and second
stringer elements is bifurcated to define a notch configured and
dimensioned to engage a respective support pedestal.
[0023] It is further contemplated that at least one end of the
first and second stringer elements includes a locking mechanism
configured and dimensioned to secure the respective stringer to the
support pedestal. Preferably, the locking mechanism is a snap-fit
type locking mechanism.
[0024] The present disclosure also provides for a method of
installing a cable support assembly in an existing raised floor
system which includes a plurality of pedestals. The method includes
the step of providing a plurality of cable support apparatus. Each
of the plurality of cable support apparatus includes first and
second stringer elements, each stringer element being configured
and adapted to be suspended on at least one pedestal of the

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0043] Referring now in specific detail to the drawings in which
like reference numerals identify similar or identical elements
throughout the several views, and initially to FIG. 1, one
illustrative embodiment of a raised floor system, constructed in
accordance with the present disclosure, is shown generally as
raised floor system 10.
[0044] Generally, raised floor system 10 includes a series of
support pedestals, such as stanchions 12, which are disposed in a
predetermined array on a base such as floor 13. A cable support
assembly is provided in raised floor system 10 and includes a
series of cable support apparatus, such as cable baskets 14, which
are disposed relative one another to form a predetermined pathway
for carrying cables or the like thereon. Preferably, cable baskets
14 form an integral part of floor system 10. Stanchions 12 are
interconnected by a plurality of stringer members 16 (see FIGS. 3
and 4) so as to define a lattice work which receives individual
floor panels 18 therein to form the completed raised floor system
10.
[0045] Although not illustrated herein, in certain installations it
may be desirable or necessary to install the cable support assembly
as a stand alone modular assembly. It is within the scope of the
present disclosure, that in such an installation, cable baskets 14
will be supported a predetermined distance above the building floor
13 by independent stanchions 12 or other suitable supports which
are not also used to support raised floor system 10.
[0046] Referring now to FIG. 2, cable basket 14 includes first and
second elongated stringer elements 20, 22, respectively, having a
channel section suspended therebetween so as to form a portion or
segment of a passageway for supporting cable runs thereon. In the
illustrated embodiment, the channel section is formed of an open
ended wire stock basket having longitudinal sections 26 disposed
across transverse sections 24. Preferably, longitudinal sections 26
are disposed atop transverse sections 24. Transverse sections 24
include up turned riser portions or legs 28 which are preferably
attached to the underside of stringers 20, 22. Alternatively, legs
28 can be attached to an upper surface, a side surface or penetrate
through stringers 20, 22. Stringers 20, 22 are preferably planar,
however, it is envisioned that stingers 20, 22 can take on any
number of configurations, including, for example, an inverted
"U-shape" or an "L-shape" configuration in order to increase the
rigidity of stringers 20, 22.
[0047] Each longitudinal section 26 includes an engaging element
such as a down turned hook portion 30 extending longitudinally from
an end of the channel section beyond the first or last transverse
section 24. Preferably, all hook portions 30 extend from the same
side of cable basket 14. As seen in FIG. 2, each hook portion 30 is
preferably integral with a respective longitudinal section 26. If
desired, less than all of longitudinal sections 26 may terminate in
hook portions 26.
[0048] Alternatively, it is further envisioned that hook portions
30 can be separate discrete elements laterally offset from
longitudinal sections 26 and fixedly mounted to cable baskets 14 or
that hook portions 30 can extend at an angle from the end of the
channel section. Preferably, when hook portions 30 of a first cable
basket 14 engage transverse sections 24 of an adjacent cable basket
14, they are not interfered with by longitudinal sections 26 of
adjacent cable baskets 14.
[0049] Preferably, as seen in FIG. 2, and in greater detail in FIG.
4, first and second stringers 20, 22 each include bifurcated
proximal and distal ends defining a notch 32. In an alternative
embodiment, as seen in FIGS. 5A-5D, proximal notch 32a has a length
which is greater than a length of distal notch 32b. As such, when
installing cable basket 14 onto stanchions 12, as seen in FIGS. 5A
and 5B, proximal notches 32a are slipped onto a corresponding
proximal stanchion 12a and advanced in a proximal direction (as
indicated by arrow "X") along the length of notch 32a until the
distal most end of stringers 20, 22 clear a distal stanchion 12b.
After the distal most end of stringers 20, 22 have cleared distal
stanchion 12b, the distal end of cable basket 14 is lowered (as
indicated by arrow "Y" in FIGS. 5A and 5B) until distal notch 32b
is aligned with distal stanchion 12b. Cable basket 14 is then moved
distally (in a direction opposite to arrow "X") until distal notch
32b is positioned about distal stanchion 12b, as seen in FIGS.
5C-5D. As will be described in greater detail below, with reference
to FIGS. 6 and 7, the proximal most end of stringers 20, 22 can be
provided with a locking mechanism 60, 72 for securing cable basket
14 to stanchions 12a.
[0050] Although the illustrated channel sections are formed of wire
stock material, it is within the scope of the present disclosure to
use other materials as well. For example, the channel section may
be formed of solid or woven fabrications of various metals, fabrics
or any other material suitable for supporting cable runs thereon.
Additionally, the channel section may be rigid or flexible
depending upon the application needs.
[0051] Referring now to FIGS. 3 and 4, the integration of cable
baskets 14 into raised floor system 10 will now be described in
detail. Preferably, each cable basket 14 is supported by four
stanchions 12, as shown in FIG. 1. However, it is within the scope
of the present disclosure that cable baskets 14 may be modified so
as to be supported by more or less than four stanchions 12.
[0052] As is common in conventional raised floor systems 10, and as
seen in FIG. 4, floor system 10 is preferably provided with a
height adjustment mechanism to adjust the height of a support plate
42 of stanchion 12 in order to accommodate slight variances in
floor 13. Support plate 42 is typically configured and adapted to
support stringer members 16 thereon. The height adjustment
capability may be facilitated by, for example, a threaded stud 48
being received in a threaded bore 50 formed in support plate 42 at
one end and in a threaded opening of stanchion 12. A nut 52 is
threaded onto stud 48 and positioned adjacent the top of stanchion
12 to facilitate vertical adjustment and positioning of support
plate 42.
[0053] As shown in FIGS. 3 and 4, cable baskets 14 are supported by
stanchions 12 such that the longitudinal and transverse elements
26, 24, respectively, are spaced a predetermined distance from
permanent floor 13. When installed, cable baskets 14 do not
interfere with the placement or fit of floor panels 18. Rather,
cable baskets 14 are designed to be incorporated into existing
raised floor systems without departing from the factory design
specifications of the floor system.
[0054] Preferably, cable baskets 14 are supported on stanchions 12
by positioning notch 32, of first and second stringers 20, 22,
about studs 48 of respective stanchions 12 such that stringers 20,
22 rest atop nut 52. It is envisioned that a second nut (not shown)
can be provided around stud 48 and above nut 52, on which stringers
20, 22 rest, in order to adjust the height of the proximal and
distal ends of cable basket 14. Notches 32 are preferably
dimensioned to be larger than studs 48, in order to be positioned
around studs 48, and dimensioned smaller than nuts 52, in order to
permit the ends of stringers 20, 22 to rest on nuts 52.
[0055] Alternatively, it is envisioned that if cable baskets 14
include inverted "U-shaped" stringers 20 and 22 (not shown), it is
preferred that a top wall portion of stringers 20, 22 is
dimensioned to be wider than the width of nuts 52 such that
stringers 20, 22 will fit over nuts 52 and that a pair of side
walls of stringers 20, 22 depend down the sides of stanchions
12.
[0056] As seen in FIGS. 3 and 4, hook portions 30 of cable baskets
14 are preferably dimensioned to extend longitudinally a distance
beyond stanchions 12. More preferably, as will be described in
greater detail below, hook portions 30 are dimensioned to engage an
end most transverse element 24 of an adjacent cable basket 14. It
is contemplated that, hook portions 30 can extend sufficiently to
engage a transverse element 24 more centrally located within cable
basket 14. While down turned hook portions 14 are disclosed, it is
envisioned that hook portions 30 can be replaced by other support
elements without departing from the scope of the present
disclosure, including and not limited to, linear elements,
laterally bent elements, a single "U-shaped" element extending
across the entire width of the channel section or a plurality of
"U-shaped" elements extending across the entire width of the
channel section, an undulating down turned support element
configured to engage each longitudinal element, at least one hook
portion extending longitudinally from legs 28, or any combination
thereof.
[0057] In use, as seen in FIG. 4, a first cable basket 14a is
positioned on stanchion 12 such that stringers 20, 22 rest atop
nuts 52. A second cable basket 14b, oriented such that hooks 30 are
directed toward first cable basket 14a, is then positioned on
stanchions 12 such that stringers 20, 22 of second cable basket 14b
preferably rest atop stringers 20, 22 of first cable basket 14a and
such that hooks 30 of second cable basket 14b rest on at least the
end most transverse section 24 of first cable basket 14a.
Additional cable baskets 14 can be installed in the same manner, in
succession, as needed. Accordingly, hooks 30 provide additional
support and stability between adjacent cable baskets 14 in raised
floor system 10.
[0058] Turning now to FIGS. 6 and 7, cable basket locking
mechanisms will be described in detail. While a single locking
mechanism can be provided on an end of either first or second
stringer elements 20, 22, it is envisioned that a locking mechanism
may be provided on both ends of each stringer element 20, 22. In
FIG. 6, the locking mechanism includes a cross-bar 60 extending
across the width of each notch 32, which cross-bar 60 inhibits
threaded stud 48 from coming out of notch 32 when cable basket 14
is mounted on stanchions 12. In particular, as seen in FIG. 6,
notch 32 is defined by a pair of longitudinally extending legs 34a,
34b. Accordingly, cross-bar 60 includes a first end pivotally
connected to leg 34a by a pin 62, or other coupling element, and a
second end including a bump 64 formed thereon. Bump 64 is
configured and adapted to engage a hole, recess or dimple 66 formed
in leg 34b. Bump 64 and recess 66 define a snap-fit type coupling,
however, other coupling arrangements are envisioned, including and
not limited to, pins, screws, etc. In use, after notch 32 is
positioned about stud 48, cross-bar 60 is pivoted about pin 62
until bump 64 engages recess 66 thus locking stringer 20 or 22 to
stanchion 12. It is envisioned that notch 32 is dimensioned to have
a depth sufficient to permit stud 48 to be received therewithin and
to permit cross-bar 60 to engage leg 34b.
[0059] As seen in FIG. 7, an alternative embodiment of the locking
mechanism is shown. In this embodiment, the proximal and distal
ends of each stringer 20, 22 terminate in a single leg 70 extending
longitudinally from a lateral side thereof. The locking mechanism
includes an "L-shape" bracket 72 having a first leg portion 74
having a first end pivotally coupled to the end of a respective
stringer 20, 22 by a pin 76 and a second leg portion 78
orthogonally extending from a second end of first leg portion 74.
Preferably, first leg portion 74 is spaced a distance from single
leg 70 when first leg portion 74 is parallel to single leg 70.
Accordingly, when first leg portion 74 is oriented to be parallel
with single leg 70, a distal end of second leg portion 78 engages
the distal end of single leg 70. Preferably, the distal end of
second leg portion 78 includes a bump 80 configured and adapted to
engage a hole, recess or dimple 82 formed in the distal end of
single leg 70. Bump 80 and recess 82 define a snap-fit type
coupling. When "L-shape" bracket 72 is in a closed position, i.e.,
bump 80 of second leg portion 78 engaging recess 82 of single leg
70, an opening 84 is defined, which opening 84 is configured and
dimensioned to receive stud 48 of stanchion 12 therein.
[0060] Turning now to FIG. 8, in an alternative embodiment, each
stringer 20, 22 may be provided with a series of slotted apertures
90 formed along the length thereof. Apertures 90 permit stanchions
12 to be placed anywhere along the length of stringers 20, 22 in
order to provide additional support. In the alternative, apertures
90 enable the construction of longer cable baskets 14, which cable
baskets 14 can span longer distances and be supported not only at
their proximal and distal ends, but along their entire length by
the existing stanchions 12 making up raised floor system 10. In
particular, the width of each stringer 20, 22 is such that stringer
20, 22 will span across and beyond stanchions 12. Each aperture 90
formed in stringers 20, 22 includes a generally rectangular slit 92
which angularly extends into a side portion of stringers 20, 22 and
opens into a generally circular space 94. Rectangular slit 92 and
circular space 94 are dimensioned to receive studs 48 of stanchions
12 in a bayonet type engagement therein, such that cable basket(s)
14 can be supported thereon.
[0061] It is contemplated that each aperture 90 can be provided
with a locking mechanism (not shown) similar to the locking
mechanisms described above in order to prevent or inhibit stringers
20, 22 from coming free of stanchions 12, or in the alternative,
stanchions 20, 22 can be provided with a single cross-bar (not
shown) which extends across all apertures 90 simultaneously. As
such, cable baskets 14 are kept from inadvertently slipping off of
or coming free of stanchions 12.
[0062] Referring now to FIGS. 9-11, an alternative embodiment of a
cable basket, in accordance with the present disclosure, is shown
generally as 114. As seen in FIG. 9, cable basket 114 is similar to
cable basket 14 in every respect except that each stringer 20, 22
includes a bifurcated distal end defining a notch 132 and a squared
off proximal end 133 which terminates substantially at a proximal
most transverse section 124a. Similar to cable basket 14, cable
basket 114 includes at least one engaging element such as down
turned hook portion 130 extending longitudinally from an end of the
channel section beyond proximal most transverse section 124a, on a
side opposite notches 132.
[0063] Turning now to FIGS. 10 and 11, installation of a series of
cable baskets 114 in an existing or a new raised floor system 10 is
shown and described. As seen in FIG. 10, cable baskets 114 are
installed into raised floor system 10 by first orienting cable
basket 114 in such as way as to slide notches 132 of stringers 20,
22 around studs 48 of a distal pair of stanchions 12a (in the
direction indicated by arrow "X"). Next, proximal end 133 of
stringers 20, 22 is lowered or approximated (in the direction
indicated by arrow "Y") toward a proximal most stanchion 12b until
down turned hook portion 130 engages at least a distal end most
transverse section 124 of an adjacent or a previously installed
cable basket 114. In this manner, as seen in FIG. 11, the distal
ends of cable baskets 114 are suspended on stanchions 12 while the
proximal end of cable baskets 114 are supported, via hook portion
130, by the distal end most transverse section 124.
[0064] Although the illustrative embodiments of the present
disclosure have been described herein with reference to the
accompanying drawings, it is to be understood that the disclosure
is not limited to those embodiments, and that various 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 by the appended claims.
