Description
CROSS-REFERENCE AND PRIORITY CLAIM TO RELATED PATENT
APPLICATION
[0001] This patent application is a divisional of U.S. patent
application Ser. No. 15/493,109, filed Apr. 20, 2017, and entitled
"Cable Management System for Telescoping Assembly", now U.S. Pat.
No. ______, the entire disclosure of which is incorporated herein
by reference.
BACKGROUND
1. Field
[0002] The present disclosure relates generally to cable management
systems and, more particularly, to a cable management system for
use in or with a telescoping assembly.
2. Information
[0003] Various devices, such as computer stands, monitor mounts,
video remote interpreting (VRI) carts, or the like may include
built-in telescoping assemblies, such as in the form of one or more
retractable poles or like sections, for example, that may allow to
adjust an associated monitor, speaker, keyboard, work area, tablet
computer, etc. to a suitable height, position, etc. In some
instances, one or more non-load-bearing cables, such as signal,
electrical, power, or like cables may run inside telescoping
assemblies, such as throughout a number of associated sections, for
example, in order to interconnect various electrical or like
components located in different portions of a device. At times,
interior cables may be prone to damage, such as snapping, breakage,
etc., which may be due, at least in part, to frequent bending,
chafing or rubbing against inner walls, edges, other cables, etc.
during repetitive extension and retraction of telescoping sections
during a typical or normal operation of a device. Repairing,
rerouting, reinstalling, etc. a cable located inside a telescoping
assembly may involve partially or completely disassembling the
assembly and/or associated device. This may be labor-intensive, may
cause expensive delays, may interrupt or reduce a service life
and/or operation of a device and/or associated assembly, or the
like. Accordingly, how to prevent or reduce damage to a cable, such
as routed through a relatively confined space of a telescoping
assembly, for example, continues to be an area of development.

SUMMARY
[0013] Example implementations relate to a cable management system
for use in or with a telescoping assembly. In one implementation, a
cable management system may comprise an outer section; an inner
section slidably mounted in the outer section for telescoping
movements, the outer and the inner sections having respective
proximal and distal ends, the proximal end of the inner section
being received in the distal end of the outer section; and a cable
assembly routed through the outer and the inner sections, the cable
assembly having a plurality of segments and being retained via
cable support members arranged within the telescoping assembly such
that a predetermined segment of the plurality of segments is
bendable during the telescoping movements.
[0014] In another implementation, a cable management system may
comprise a system for use in a telescoping assembly of a type
capable of telescoping movements via raising or lowering an inner
section about a vertical axis, the telescoping assembly may further
comprise an outer section and the inner section mounted in the
outer section for the telescoping movements, the outer and the
inner sections having respective proximal and distal ends, the
proximal end of the inner section being received in the distal end
of the outer section; and a cable assembly routed through the outer
and the inner sections, the cable assembly comprising a cable body
and a plurality of segments having respective lengths at least
partially defined via one or more stoppers fixedly disposed on the
cable body, the cable assembly being retained via a plurality of
cable support members arranged within the telescoping assembly such
that a particular predetermined segment of the plurality of
segments is bent during the telescoping movements in a controlled
manner.
[0015] In yet another implementation, a cable assembly for use with
a telescoping assembly may comprise a flexible cable body; and one
or more stoppers fixedly disposed on the flexible cable body at one
or more predetermined locations and adapted to cooperate with one
or more cable support members of the telescoping assembly so as to
facilitate bending of a portion of the flexible cable body in a
controlled manner. It should be understood, however, that these are
merely example implementations, and that claimed subject matter is
not limited to these particular implementations.
DETAILED DESCRIPTION
[0016] In the following detailed description, numerous specific
details are set forth to provide a thorough understanding of
claimed subject matter. However, it will be understood by those
skilled in the art that claimed subject matter may be practiced
without these specific details. In other instances, methods,
assemblies, and/or components thereof that would be known by one of
ordinary skill have not been described in detail so as not to
obscure claimed subject matter.
[0017] Some example implementations relating to a cable management
system for use in or with a telescoping assembly are disclosed
herein. In this context, the terms "telescoping sections,"
"telescoping assembly," or simply "assembly" may be used
interchangeably and refer to an assembly comprising a plurality of
sections or like structures having progressively different
cross-sections (e.g., smaller cross-sections, etc.) nested within
each other and capable of telescoping movements relative to each
other. As used herein, "telescoping movement" refers to a sliding
movement of one or more sections of a telescoping assembly, such as
an inner section, for example, in relation to another section of
the assembly, such as an outer section, for example, or vice versa.
As a way of illustration, a telescoping movement of an inner
section out of an outer section may lengthen a telescoping
assembly, for example, and a telescoping movement of an inner
section into an outer section may shorten the assembly, for
example.
[0018] As alluded to previously, telescoping assemblies may, for
example, be implemented in connection with a variety of devices,
such as computer stands, monitor mounts and/or arms, or the like,
such as for purposes of adjusting a device or a portion thereof to
a suitable length, height, position, etc. At times, one or more
cables, such as non-load-bearing cables (e.g., power, data, etc.)
interconnecting various electrical or like components located in
different portions of a device may, for example, be disposed on the
interior of a telescoping assembly, such as routed through a number
of associated sections, as was also indicated. In some instances,
during normal or typical operation of a telescoping assembly and/or
associated device, repetitive telescoping movements, such as via
continual extension and retraction of one or more sections for
height, length, position, etc. adjustments, for example, may damage
a cable or a portion thereof located within the interior of the
assembly, which may lead to and/or require time-consuming,
labor-intensive, costly, etc. maintenance and/or repair.
Accordingly, it may be desirable to develop one or more systems
and/or apparatuses that may implement a more effective and/or more
efficient cable management system for use in or with a telescoping
assembly, such as via facilitating bending of an interior cable or
a portion thereof in a controlled manner during telescoping
movements, for example.
[0019] As was also indicated, in at least one implementation, a
telescoping assembly may be implemented, at least in part, in or
with a cart, such as a video remote interpreting (VRI) cart, as one
example, so as to enable adjustments of an associated monitor,
speaker, tablet computer, or other components to a height,
position, etc. that allows a user to more clearly see and/or hear
an on-screen sign language interpreter, health care provider, or
the like. Claimed subject matter is not so limited, of course. For
example, any other suitable cart, device, etc., medical or
otherwise, that may utilize cabling routed through the interior of
an associated telescoping assembly may be employed herein, such as
without deviating from the scope and/or spirit of claimed subject
matter.
[0020] A particular implementation of a VRI cart, referenced herein
at 100, which may be used, in whole or in part, to implement a
cable management system, such as discussed herein, for example, is
illustrated in schematic diagrams of FIGS. 1-3 showing a front,
back, and side views of VRI cart 100, respectively. It should be
noted that like numerals may designate like parts throughout FIGS.
1-3, as well as other figures of the present disclosure, such as to
indicate corresponding and/or analogous structures, components,
etc. It should also be appreciated that structures, components,
etc. illustrated have not necessarily been drawn to scale, such as
for simplicity and/or clarity of illustration. For example,
dimensions of some components may be exaggerated relative to other
components. Further, it is to be understood that other embodiments
may be utilized. Furthermore, structural and/or other changes may
be made without departing from the scope and spirit of claimed
subject matter. It should also be noted that directions and/or
references, such as, for example, up, down, top, bottom, and so on,
if applicable or appropriate, may be used to facilitate and/or
support discussion and are not intended to restrict application of
claimed subject matter. Therefore, the following detailed
description is not to be taken to limit claimed subject matter
and/or equivalents.
[0021] As seen, VRI cart 100 may comprise, for example, a mobile or
so-called "rolling" cart capable of being moved around a surface
(e.g., a floor, etc.) within a suitable environment (e.g., a health
care establishment, interpreter services establishment, etc.), such
as via a plurality of caster wheels 102 that may be rotatably
attached to a base 104 via any suitable attachment means. Base 104
may, for example, be anchored to one end of a lower pole 106, such
as via a screw 108, for example. As illustrated, here, lower pole
106 may comprise, for example, an outer section of a telescoping
assembly 110 associated with VRI cart 100. Lower pole 106 may, for
example, be in sliding engagement with an upper pole 112, which may
comprise an inner section of telescoping assembly 110. Particular
examples of inner and outer sections as well as associated
components, structures, etc. will be discussed in greater detail
below. As seen, upper pole 112 may nest within lower pole 106, such
as by virtue of having a smaller diameter, for example, so as to
allow for telescoping movements of upper pole 112 relative to lower
pole 106, for this particular implementation. Thus, as also seen,
in some instances, a particular telescoping assembly, such as
telescoping assembly 110 associated with VRI cart 100, for example,
may be of a type capable of telescoping movements about a vertical
axis, such as via extension or retraction of upper pole 112, thus,
making telescoping assembly 110 longer or shorter, respectively. At
times, upper pole 112 of telescoping assembly 110 may also be
capable of rotational movements about a horizontal axis, such as in
relation to lower pole 106, for example.
[0022] As particularly seen in FIG. 3, VRI cart 100 may further
comprise, for example, a cable assembly 114 that may be routed
through telescoping assembly 110 or any suitable portion thereof,
such as to interconnect one or more electrical or like components
located in different portions of VRI cart 100. For this particular
implementation, cable assembly 110 may, for example, interconnect
one or more components located inside a power hub housing 116,
which may be attached to lower pole 106 via one or more collars
118, as one possible example, with a tablet computer 120 and/or
speaker 122, which may be attached to upper pole 112 via respective
mounts 124 and 126. As also illustrated, VRI cart 100 may comprise,
for example, one or more levers, referenced generally at 128, such
as to securely hold one or more components of VRI cart 100 (e.g.,
upper pole 106, tablet computer 120, etc.) at a suitable position,
angle, height, etc., such as via friction, for example. As also
seen, VRI cart 100 may include a basket 130, such as for holding
suitable items, for example, and a handle 132, such as for moving
VRI cart 100 around a suitable surface. Basket 130 and handle 132
may, for example, be fixedly attached to lower pole 106 via a
collar 134 using any suitable attachment means (e.g., screws,
bolts, etc.). In some instances, VRI cart 100 may also include a
cord wrap or like structure, referenced generally at 136, for
example, such as for wrapping, coiling, etc. any suitable cable,
cord, etc., if suitable or desired. Again, it should be noted that,
even though VRI cart 100 and/or telescoping assembly 110 is
illustrated herein as having a particular configuration,
components, attachments, etc., VRI cart 100 and/or telescoping
assembly 110 may, for example, be implemented via any other
suitable configuration, components, attachments, or the like.
[0023] Attention is now drawn to FIG. 4, which is an axial
cross-sectional view of an example implementation of a telescoping
assembly, such as telescoping assembly 110 associated with VRI cart
100 illustrated in FIGS. 1-3, for example. As seen, telescoping
assembly 110 may comprise, for example, an outer section 138 and an
inner section 140 that may be slidably mounted in outer section 138
for relative telescoping movements, as was previously discussed.
Outer section 138 and inner section 140 of telescoping assembly 110
may have respective proximal and distal ends. For example, outer
section 138 may have a distal end 142 and a proximal end 144, and
inner section 140 may have a distal end 146 and a proximal end 148.
Thus, for this example implementation of telescoping assembly 110,
proximal end 148 of inner section 140 may, for example, be received
in distal end 142 of outer section 138, such as to facilitate
telescoping movements. As also seen, inner section 140 may, for
example, be slidably secured in outer section 138 via a guiding
block 150 retainably housed in distal end 142 of outer section 138.
In some instances, guiding block 150 may, for example, be attached
to an inner surface of outer section 138, such as via any suitable
attachment means (e.g., a screw, via a friction fit, lever 128,
etc.). As such, in at least one implementation, telescoping
assembly 110 may be capable of telescoping movements about a
vertical axis, for example, and/or rotational movements about a
horizontal axis, as was indicated. Again, claimed subject matter is
not limited to a particular device, assembly, movements, attachment
means, etc., of course.
[0024] As also illustrated, telescoping assembly 110 may comprise,
for example, a cable assembly 114 that may be routed through inner
and outer sections 140 and 138, or any portion and/or combination
thereof. Cable assembly 114 may comprise, for example, a
non-load-bearing cable, such as power, signal, data, or like cable
that may be connectable to one or more sources of an electrical
signal. FIG. 5 is an illustrative view of two example
implementations of cable assemblies, referenced herein via arrows
at 502 and 504, that may be used, in whole or in part, in
connection with a telescoping assembly, such as telescoping
assembly 110 of FIG. 4, for example. As seen, in some instances,
cable assemblies 502 and 504 may comprise, for example, unibody
cable structures having respective cable bodies 506 and 508 and one
or more stoppers, referenced generally at 510 and 512, fixedly
disposed on cable bodies 506 and 508, respectively, at
predetermined locations. A stopper, such as stopper 510 and/or 512
may comprise, for example, any suitable structure having a
transverse dimension or cross-section (e.g., a diameter, width,
etc.) larger than a transverse dimension of an associated cable
body (e.g., a diameter, width, etc.), such as cable body 506 and/or
508. As will be seen, a larger transverse dimension or
cross-section of stoppers 510 and/or 512 may facilitate retention
of an associated cable assembly within telescoping assembly 110, as
will be seen. In one particular implementation, a plurality of
stoppers made of thermoplastic material, such as polyvinyl chloride
(PVC) overmolded into a particular cable body at a number of
predetermined locations were used. Of course, claimed subject
matter is not limited in this regard.
[0025] As also seen, in an implementation, cable assemblies 502 and
504 may comprise, for example, a number of suitable connectors,
such as a Universal Serial Bus (USB) connector, referenced at 514
(e.g., for cable assembly 502) and 516 (e.g., for cable assembly
504), micro USB connector, referenced at 518, iPhone.RTM.
connector, referenced at 520, just to illustrate a few possible
implementations. These or like connectors may, for example, be
positioned at respective terminal ends of cable assemblies 502 and
504, and may be sized to join with one or more suitable outlets,
ports, plugs, sockets, adapters, or the like, such as to connect
cable assemblies 502 and 504 to one or more sources of an
electrical signal, as was indicated. As also illustrated, in some
instances, a particular cable assembly, such as cable assembly 502,
for example, may include a suitable circuit assembly (e.g., a
printed circuit board assembly (e.g., PCBA), etc.), referenced at
522. Again, it should be noted that these are merely example
details relating to particular implementations of cable assemblies
that may be used, in whole or in part, in connection with a
telescoping assembly (e.g., telescoping assembly 110 of FIG. 4,
etc.), such as discussed herein, and that claimed subject matter is
not limited in this regard. For example, cable assemblies 502 and
504 may comprise any other suitable connectors, PCBAs, stoppers,
etc. or any suitable number of connectors, PCBAs, stoppers, etc. As
discussed below, a cable assembly, such as cable assembly 502
and/or 504, for example, may cooperate with one or more components
of an associated telescoping assembly (e.g., telescoping assembly
110 of FIG. 4, etc.), such as to facilitate bending of a
predetermined segment of a cable assembly in a controlled manner
during telescoping movements.
[0026] Thus, referring now back to telescoping assembly 110 of FIG.
4, in an implementation, cable assembly 110 may comprise, for
example, a plurality of segments, which may or may not be
contiguous. In some instances, segments may, for example, have
respective lengths defined via one or more stoppers and/or one or
more cable support members. To illustrate, for this particular
example, cable assembly 110 may comprise, for example, a first
segment 152, such as having a length defined via cable support
member 154 and a stopper 156, a second segment 158, such as having
a length defined via a stopper 160 and a stopper 162, a third
segment 164, such as having a length defined via stopper 162 and a
stopper 166, and a fourth segment 168, such as having a length
defined via a stopper 170 and cable support member 172. Again,
claimed subject matter is not limited to particular segments
shown.
[0027] As was indicated, in an implementation, cable assembly 114
may be fixedly retained within telescoping assembly 110 via a
number of cable support members, such as cable support members 154,
174, 176, 178, and 172, for example. As seen and as will be
discussed in greater detail below, cable support members 154, 174,
176, 178, and 172 may, for example, be arranged within telescoping
assembly 110 substantially longitudinally, such that a
predetermined segment of a plurality of segments 152, 158, 164, and
168 is bendable during telescoping movements of inner section 140,
such as in a controlled manner. As was discussed, at times, this
may, for example, prevent or reduce damage to cable assembly 114 or
a portion thereof during telescoping movements. Particular
implementations of cable support members will now be discussed,
such as by way of non-limiting examples.
[0028] Thus, according to an implementation, cable support members
154 and 172 may comprise, for example, cable retainers having
respective through-apertures aligned with through-apertures in
suitable portions of walls of inner and outer sections 140 and 138.
As illustrated, these through-apertures may, for example, be sized
for conducting cable assembly 114 therethrough, such as for
purposes of connecting cable assembly 114 to one or more sources of
an electrical signal, as was indicated. At times, cable support
members 154 and 172 may, for example, be capable of fixedly
securing or anchoring respective ends or other portions of cable
assembly 114 to telescoping assembly 110, such as via a friction
fit, as one possible example. As seen, in this example, cable
support member 172 anchoring one end of cable assembly 114 may be
positioned at a suitable distance from proximal end 144 of outer
section 138, such as at a mid-point between a middle portion of
outer section 138 and its distal end 144, just to illustrate one
possible implementation. As also seen, in some instances, cable
support member 154 anchoring another end of cable assembly 114 may,
for example, be positioned proximate to distal end 146 of inner
section 140, though, again, claimed subject matter is not so
limited. For example, cable support members 154 and 172 may be
positioned at any other suitable locations on inner and outer
sections 140 and 138, cable assembly 114 may be anchored to
telescoping assembly 110 via any other suitable attachment means,
or the like.
[0029] In an implementation, cable support member 174 may comprise,
for example, a guiding block fixedly mounted to an outside surface
of inner section 140, such as via any suitable attachment means
(e.g., screws, friction, etc.). In some instances, cable support
member 174 may, for example, be mounted proximate to proximal end
148 of inner section 140, such as for functioning conjointly with
inner section 140 during telescoping movements. As such, cable
support member 174 may, for example, slidably travel between cable
support member 176 and guiding block 150, such as during
telescoping movements of telescoping assembly 110, as will also be
seen.
[0030] Continuing with the above discussion, in an implementation,
cable support member 176 may comprise, for example, a retainer
fixedly mounted via any suitable means to an inside surface of
outer section 138, such as at a suitable distance from distal end
142 of outer section 138 and/or guiding block 150. In some
instances, cable support member 176 may comprise, for example, a
retainer adapted to conduct cable assembly 114 therethrough while
fixedly retaining at least a portion of cable assembly 114 within
telescoping assembly 110, such as via one or more stoppers (e.g.,
stoppers 166, 170). Thus, as discussed below, cable support member
176 may comprise, for example, one or more apertures sized to at
least partially receive one or more stoppers disposed on cable
assembly 114. As particularly seen in FIG. 6, which is an enlarged
axial cross-sectional view of telescoping assembly 110 of FIG. 4,
such as referenced in FIG. 4 via a dashed line at 182, cable
support member 176 may, for example, conduct cable assembly 114
therethrough while fixedly retaining at least a portion of cable
assembly 114 via one or more stoppers sized to be at least
partially received in one or more apertures of cable support member
176 (e.g., stoppers 166 and 170).
[0031] An example implementation of cable support member 176, which
may comprise a retainer, for example, referenced herein at 700, is
illustrated in FIGS. 7A and 7B, which are axial and perspective
views of retainer 700, respectively. As seen, in some instances,
retainer 700 may be configured to at least partially retain a
plurality of cable assemblies and, as such, may comprise, for
example, a plurality of apertures, referenced herein at 702 and
704, such as for respective cable assemblies. Apertures 702 and 704
may, for example, extend through retainer 700 and may be sized to
at least partially receive applicable stoppers (e.g., stoppers 166
and 170 of FIG. 6, etc.), as was indicated. As also seen, retainer
700 may further comprise an apertured through-portion 706 so as to
slidably receive another cable support member (e.g., cable support
member 178 of FIG. 4, etc.), for example, as will be discussed
below. Retainer 700 may also include one or more cut-out portions,
such as cut-out portions 708 and 710, for example, such as for
routing respective cable assemblies towards one or more sources of
an electrical signal (e.g., towards power hub housing 116). At
times, retainer 700 may also include one or more through-portions
or cut-outs, referenced at 712 and 714, which may be grooved, for
example, such as for adjustably securing retainer 700 to an outer
section of a telescoping assembly (e.g., outer section 138).
[0032] Referring back to FIG. 6, as seen, cable support member 174
(e.g., a guiding block) may, for example, be fixedly coupled to
cable support member 178, discussed below, via a coupling element
184 so as to engage cable support member 178 for functioning
conjointly with inner section 140 during telescoping movements. As
also illustrated, coupling element 184 may be matingly received
within proximal end 148 of inner section 140, for example, and may
abut proximal end 148 so as to slidably extend through apertured
portion 186 (e.g., aperture 706 of FIG. 7) of cable support member
176. Coupling element 184 may, for example, be fixedly attached to
inner section 140 via any suitable attachment means (e.g., bolts,
screws, etc.).
[0033] An example implementation of coupling element 184, which may
comprise a cable bushing, for example, referenced at 800, is
illustrated in FIG. 8, such as via a perspective view. As seen,
cable bushing 800 may have a relatively circular cross-section that
may be sized to match an inside surface of a particular inner
section (e.g., inner section 148 of FIG. 6, etc.) of a telescoping
assembly (e.g., telescoping assembly 110 of FIG. 6, etc.), for
example. Cable bushing 800 may include, for example, a rimmed
portion 802 substantially surrounding one edge of cable bushing
800, such as an edge facing another cable support member (e.g.,
cable support member 178 of FIG. 6, etc.), as one possible example.
Within a particular telescoping assembly (e.g., telescoping
assembly 110), rimmed portion 802 may, for example, be sized so as
to be seated upon a rim of a particular inner section (e.g., inner
section 148 of FIG. 6, etc.) and/or another cable support member
(e.g., cable support member 174), if applicable.
[0034] Further, in some instances, cable bushing 800 may include
one or more apertured portions or cut-outs, illustrated herein at
804, 806, 808, and 810, for example, such as for fixedly retaining
at least a portion of an associated cable assembly therewith, such
as via applicable stoppers, as was indicated. Cable bushing 800 may
also comprise one or more openings or cut-outs, referenced
generally at 812, such as for purposes of receiving applicable
attachment means, or any portion thereof, so as to secure cable
bushing 800 to a particular inner section (e.g., inner section 148
of FIG. 6, etc.) of a telescoping assembly (e.g., telescoping
assembly 110 of FIG. 6, etc.) and/or another cable support member
(e.g., cable support member 174 of FIG. 6, etc.), for example.
[0035] As also illustrated, cable bushing 800 may comprise, for
example, a central aperture 814, such as for purposes of fixedly
mounting or attaching cable bushing 800 to another cable support
member (e.g., cable support member 178 of FIG. 6, etc.). For
example, as illustrated in FIG. 4, coupling element 184 (e.g.,
cable bushing 800 of FIG. 8) may be used, at least in part, to
couple inner section 140 to cable support member 178, which may
abut proximal end 148 of inner section 140 so as to slidably extend
through an apertured portion of cable support member 176 (e.g.,
aperture 706 of retainer 700 of FIG. 7) and terminate at a
free-standing distal end 180. Again, it should be noted that
claimed subject matter is not limited to particular implementations
shown. For example, a person skilled in the art will appreciate
that one or more modifications may be made without deviating from
the scope and/or spirit of claimed subject matter.
[0036] Referring now to FIGS. 9A-C, which are perspective, front,
and side views, respectively, of cable support member 178 of FIGS.
4 and 6, according to an implementation. As seen, in some
instances, this cable support member may comprise, for example, a
cable guide, referenced at 900, having a fork-shaped structure
comprising a handle portion 902 and a fork portion 904 having a
plurality of tines, referenced at 906, 908, and 910. Depending on
an implementation, fork portion 904 may be made separately and
mounted on handle portion 902, for example, or may be made integral
with handle portion 902, or any combination thereof. For example,
as illustrated, fork portion 904 may be formed via fixedly securing
a U-shaped segment 912 of fork portion 904 to an extended bar stock
or tang of handle portion 902, such as via an arcuate section 914.
As also seen, arcuate portion 914 may, for example, smoothly blend
or merge into tines 906 and 908, thus, forming U-shaped segment
912. In at least one implementation, tines 906, 908, and 910 may
have a substantially circular cross-section, though claimed subject
matter is not so limited. U-shaped segment 912 may, for example, be
secured to an extended bar stock or tang of handle portion 902 via
any suitable attachment means (e.g., by welding, etc.), such as to
arrive at a fork-shaped structure.
[0037] In an implementation, a proximal end 916 of cable guide 900
may, for example, be adapted for fixedly mounting or attaching
cable guide 900 to a suitable telescoping section of a telescoping
assembly (e.g., inner section 140 of FIG. 4, etc.), such as via any
suitable coupling means (e.g., coupling element 800 of FIG. 8,
etc.). As such, in some instances, cable guide 900 may, for
example, be capable of functioning conjointly with a particular
telescoping section of an associated telescoping assembly (e.g.,
inner section 140 of FIG. 4, etc.). As was also indicated, cable
guide 900 may, for example, have a free-standing distal end,
referenced herein via an arrow at 918.
[0038] Continuing with the above discussion, in an implementation,
tines 906, 908, and 910 may be spaced apart from each other, such
as laterally, as one possible example, so as to form one or more
longitudinal slots, referenced generally at 920 and 922. In some
instances, longitudinal slots 920 and 922 may, for example, be
employed for receiving one or more cable assemblies therethrough
(e.g., cable assemblies 502 and 504 of FIG. 5). At times,
longitudinal slots 920 and 922 may also be capable of retaining at
least a portion of one or more cable assemblies, such as via one or
more stoppers, as will also be seen. Thus, tines 906, 908, and 910
may, for example, be spaced apart a distance less than a transverse
dimension or cross-section (e.g., a diameter, width, etc.) of one
or more stoppers arranged to be in contact with tines 906, 908,
and/or 910 during telescoping movements. For example, spacing
between tines 906, 908, and/or 910 may be sufficient to let a cable
body of an associated cable assembly to pass freely through a
corresponding longitudinal slot, while detaining one or more
stoppers due, at least in part, to their larger transverse
dimension or cross-section.
[0039] As also illustrated, in some instances, tines 906, 908, and
910 may, for example, be arranged in a slightly triangular
disposition, such as with respect to one or more planes, though
claimed subject matter is not so limited. For example, in certain
implementations, tines 906, 908, and 910 may be arranged
substantially laterally and/or parallel throughout their lengths,
which is a matter of design choice. Also, cable guide 900 may, for
example, be made of any suitable material, such as metal,
sufficiently rigid plastic, etc., or any combination thereof, which
may also be a matter of design choice. It should be noted that, in
one particular implementation, cable guide 900 made of stainless
steel was used, though, again, claimed subject matter is not
limited in this regard. It should also be appreciated that cable
guide 900 may comprise any suitable number of tines, which may
depend, at least in part, on a number of routed cable assemblies, a
particular telescoping assembly, associated device, implementation,
or the like.
[0040] Referring back to FIG. 6, as seen, in an implementation,
cable support member 178, such as a fork-shaped cable guide, for
example, may retain at least a portion of cable assembly 114, such
as via stopper 162. Namely, as illustrated, a cable body of cable
assembly 114 may be drawn through a longitudinal slot formed by
tines 906 and 910, for example, may be and looped upon itself such
that stopper 162 is detained between tines 906 and 910, such as at
a point proximate to arcuate portion 914, as one possible example.
As illustrated, stopper 162 may, for example, be detained by
resting against tines 906 and 910, such as due, at least in part,
to its larger transverse dimension or cross-section (e.g., a
diameter, width, etc.) relative to spacing between tines 906 and
910 defined by a corresponding longitudinal slot, as was previously
discussed. In addition, stopper 162, such as in conjunction with
stopper 160, for example, may limit bending, twisting, or like
motions of second segment 158 of cable assembly 114 during
telescoping movements. For example, as seen in this particular
implementation, segment 158 may be kept substantially straightened
and/or immobilized during telescoping movements of telescoping
assembly 110, such as relative to cable support member 178
functioning conjointly with inner section 140. It should be noted
that stopper 162 may be arranged on any suitable side and/or
portion of a fork portion of cable support member 178. As discussed
below, stopper 162 may facilitate bending of a predetermined
segment of cable assembly 114, such as segment 164, for example,
via a corresponding longitudinal slot in a controlled manner during
telescoping movements of telescoping assembly 110.
[0041] Thus, as illustrated progressively in FIGS. 10A-10C via
axial cross-sectional views of an example implementation of a
telescoping assembly associated with a cart, such as telescoping
assembly 110 associated with VRI cart 100, for example, in
operative use, inner section 140 may be pulled up or extended from
its retracted position (e.g., FIG. 10A) towards its extended
position (e.g., FIG. 10C), such as for one or more suitable
adjustments. As inner section 140 extends, as referenced
schematically via an arrow at 188, cable support members 154, 174,
and 178, being fixedly attached to inner section 140 via suitable
attachment means, such as discussed above, for example, may move
synchronously with inner section 140. Since particular segments of
cable assembly 114, such as segments 152 and 158, for example, are
fixed in relative positions via applicable cable support members
functioning conjointly with inner section 140, as also discussed
above, these segments may also move synchronously with inner
section 140. As such, as illustrated in this particular example,
segments 152 and 158 may remain substantially straightened and/or
immobilized during telescoping movements of telescoping assembly
110, such as during upward movement 188, for example. At times,
this may, for example, limit bending, twisting, or like motions of
these segments and, as such, prevent or reduce damage to cable
assembly 114, as was also indicated. As also seen, segment 168 may,
for example, remain substantially stationary during telescoping
movements, such as by virtue of being anchored to outer section 138
and also fixedly secured to cable support member 176, such as via
stopper 170, which may also prevent or reduce associated
damage.
[0042] As particularly seen in FIG. 10C, cable support member 178
(e.g., cable guide 900 of FIG. 9) may be in a looped relation with
a particular segment of cable assembly 114, such as segment 164,
for example, so at to facilitate bending of segment 164 in a
controlled manner. This may, for example, be implemented, at least
in part, via directing or guiding a cable body of segment 164 to
travel (e.g., move, slide, etc.) along and/or loop though a
longitudinal slot formed by applicable tines of an associated fork
portion (e.g. longitudinal slot 920 and/or 922 of FIGS. 9A and 9B,
etc.), such as due, at least in part, to gravity, resilient nature
of an associated cable body, or the like. As such, here, a
particular predetermined segment of a plurality of segments of a
cable assembly may, for example, be bendable during telescoping
movements. By way of example but not limitation, in a particular
implementation shown, only segment 164 may, for example, be
bendable during telescoping movements of telescoping assembly 110,
such as illustrated via upward movement 188. A length of a
longitudinal slot formed by applicable tines may, for example, be
sized appropriately, such as to prevent disengagement or slippage
of segment 164 from a free-standing end of a fork portion (e.g.,
end 918 of FIGS. 9A-C) of cable support member 178. For example, a
length a particular longitudinal slot may be selected to be longer
than a length of a chord or like segment of a looped portion of a
cable assembly, which may be measured while an inner portion of a
telescoping assembly is fully extended. Claimed subject matter is
not so limited, of course. Any other suitable approaches may be
utilized herein so as to prevent disengagement or slippage of
segment 164 from cable support member 178. For example, in some
instances, segment 164 may be attached or secured to a fork portion
of cable support member 178 via a tie wrap or like cable tie.
[0043] Accordingly, as was indicated, a cable management system for
a telescoping assembly, such as disclosed herein, may provide
benefits. For example, by having a particular predetermined segment
of a cable assembly bend in a controlled manner, a likelihood of
the cable assembly being caught by surrounding edges, walls, etc.
of the interior and, thus, associated cable damage may be
eliminated or reduced. In addition, guiding a cable assembly to
travel and/or loop in a controlled manner during telescoping
movements, such as via a longitudinal slot may, for example,
prevent or reduce cable twisting, entanglement, or the like. As
such, a service life and/or operation of a particular device (e.g.,
VRI cart 100, etc.) and/or associated telescoping assembly may, for
example, be extended. Of course, such a description of certain
aspects of a cable management system for a telescoping assembly and
its benefits is merely an example, and claimed subject matter is
not so limited.
