Description
RELATED APPLICATIONS
[0001] This is a continuation patent application of U.S. patent
application Ser. No. 10/773,110 filed on Feb. 4, 2004, which is a
continuation-in-part application of U.S. patent application Ser.
No. 10/211,883 filed on Aug. 1, 2002 and issued as U.S. Pat. No.
6,834,768, both of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] Racks of many different configurations are currently
available in the food and beverage industry. A number of such racks
are employed to store any type of beverage container, including
without limitation bottles, boxes, crates, bags, kegs, barrels, and
other containers capable of holding fluid. By way of example only,
racks are often employed to support syrup containers used in
post-mix beverage blending. As is well known in the art, the syrup
in such containers is pumped, drained, or otherwise removed from
the containers and is often mixed with water or water and gas to
yield a post-mix beverage. In those cases where gas is mixed with
the syrup, the gases can include carbon dioxide, nitrogen, a
combination of carbon dioxide and nitrogen, or any other gas or gas
combination.
[0003] An example of a fluid container commonly used in the food
and beverage industry is the "bag-in-box" container, whereby a
comestible fluid (such as a beverage, a syrup or other beverage
concentrate, and the like) is contained within a bag enclosed
within a box for support. A tap and pump is often employed to
extract the comestible fluid from the bag. For example, a tap can
be positioned toward the bottom of the bag to enable the fluid to
be more completely removed from the bag via a conduit between the
tap and pump. In some cases, a metering valve is connected to the
bag and pump in order to meter the flow of comestible fluid from
the pump or bag. During post-mix beverage blending, a metered
supply of syrup is typically mixed with water or with water and a
metered amount of gas. Water mixed with comestible fluid from the
bag is often chilled to a point within a temperature range in order
to promote optimum saturation of gas within the water and syrup
mixture.
[0004] Currently available comestible fluid container racks are
often inadequate for the needs of many users, and even for the
process of dispensing comestible fluid from containers on such
racks (e.g. in post-mix preparation and in the preparation of other
types of beverages). Such comestible fluid container racks can be
found in restaurants, bars, concession stands, and the like.
[0005] Problems and limitations with conventional comestible fluid
container racks include the inability to change the capacity of
such racks (whether by changing the size of a rack or by easily and
readily adding to the rack), inadequate provisions for mounting or
organizing components associated with the dispense of comestible
fluid from the containers, and rack designs that are difficult and
time-consuming to set up, disassemble, and/or transport. Such
components can include pumps, filters, valves, regulators,
treatment devices, and conduits to connect such components.
[0006] The mounting and arrangement of such components in
comestible fluid storage and dispensing systems also presents
problems and limitations well known in the art (regardless of
whether a rack as described above is employed). By way of example
only, these problems and limitations include haphazard and
disorganized systems and systems in which systems components are
difficult and time-consuming to service, replace, and maintain. In
some cases, it can be difficult for a user or other party to even
identify which components in the system are associated with which
other components.
[0007] In light of the problems and limitations of the prior art
described above, a need exists for a comestible fluid container
rack that is expandable, adjustable, can be relatively easily
assembled and disassembled, can be transported, enables a user to
mount and/or organize components of a comestible fluid dispensing
system thereon, is relatively simple in construction, and is low in
cost. Each embodiment of the present invention achieves one or more
of these results.
SUMMARY OF THE INVENTION
[0008] Some embodiments of the present invention provide a
comestible fluid container rack for holding comestible fluid
containers from which comestible fluid is dispensed. In some
embodiments, the rack is expandable in order to connect additional
portions of the rack for added rack capacity. In these and in other
embodiments, the rack can be adjustable to meet the needs of
various users.
[0009] In some embodiments, the comestible fluid container rack
includes stackable rack modules. The rack modules allow a user to
expand or reduce the amount of available space for comestible fluid
containers in the rack by stacking additional rack modules upon one
another or by removing one or more rack modules from a stack,
respectively. This can enable users to purchase limited numbers of
rack modules at a time to more effectively match the needs of the
user. In some cases, one or more of the rack modules can be
connected to vertically adjacent rack modules (e.g., located above
or below the rack module(s)) by one or more couplings. The
couplings can enable rack modules to be vertically stacked in a
stable manner, and can permit the rack modules to be quickly
disassembled, transported, and reassembled as needed. In some
embodiments, the rack modules can be disassembled, transported,
and/or re-assembled without disturbing comestible fluid containers
and comestible fluid dispensing components (such as comestible
fluid conduits, valves, pumps, regulators, filters, and the like)
on the rack modules.
[0010] The comestible fluid container rack of the present invention
can have rack modules with telescoping rails enabling a user to
adjust the space between vertical supports of the rack. This
feature can permit a user to adjust the rack or rack modules to fit
comestible fluid containers of different sizes. In some
embodiments, each rack module can be independently adjusted to
accommodate comestible fluid containers of different sizes. This
feature can reduce the need for users to rearrange or relocate
comestible fluid containers when containers of different sizes are
to be placed on the rack.
[0011] Another aspect of the present invention relates to the
manner in which comestible fluid dispensing components are mounted
(whether on a comestible fluid container rack as described above or
to another structure). In particular, some embodiments of the
present invention provide a bracket to which a valve, pump,
regulator, filter, or other fluid dispensing system component can
be releasably mounted. The bracket can be moved and secured to
different positions along a rail in order to provide mounting
flexibility for installers, those who maintain or service the
comestible fluid dispensing system (or components thereof), and
other users. For example, the bracket can be slidable and securable
to different positions along the rail. If desired, the rail can be
attached to a comestible fluid container rack, such as to the
vertical supports of a rack.
[0012] In some embodiments of the present invention, a comestible
fluid container rack is provided having one or more supports on the
rack positioned to support one or more comestible fluid containers.
Each support can include a brace adapted to hold and/or support one
or more comestible fluid conduits associated with the comestible
fluid containers. In this manner, the braces can be employed to
organize and secure the comestible fluid conduits in the rack,
avoiding the conventional practice of haphazardly routing unsecured
comestible fluid conduits in the rack.
[0013] Some embodiments of the present invention provide a
comestible fluid container rack adapted to support a comestible
fluid container, wherein the comestible fluid container rack
comprises a first vertical support, a second vertical support, a
first stretcher extending from the first vertical support, a second
stretcher extending between the first and second vertical supports
and coupled to the first stretcher, a first support coupled to and
extending from the first stretcher, and a second support coupled to
and extending from the second stretcher, wherein the second support
is movable with respect to the first support such that at least a
portion of the second support overlaps at least a portion of the
first support in at least one relative position of the second
support with respect to the first support.
[0014] In another aspect of the present invention, a comestible
fluid container rack adapted to support a comestible fluid
container is provided, and comprises a first vertical support, a
second vertical support, a first stretcher extending from the first
vertical support, a second stretcher extending between the first
and second vertical supports and coupled to the first stretcher, a
first support coupled to and extending from the first stretcher,
and a second support coupled to and extending from the second
stretcher, wherein the second support is movable with respect to
the first support such that at least a portion of the second
support nests within a portion of the first support in at least one
relative position of the second support with respect to the first
support.
[0015] In some embodiments, a comestible fluid container rack
adapted to support a comestible fluid container is provided, and
comprises first and second vertical supports, a first stretcher
coupled to and extending laterally between the first and second
vertical supports, a support coupled to the first stretcher at a
location between the first and second vertical supports, and an
extension coupled to and extending substantially laterally with
respect to the support, wherein the extension has at least one
surface upon which the comestible fluid container rests and defines
a widened area of support upon which the comestible fluid container
rests.
[0016] In yet another embodiment of the present invention, a
support adapted to support a comestible fluid container on a
comestible fluid container rack having front and rear lateral
stretchers is provided, and comprises a first portion adapted to be
supported on opposite ends by the front and rear stretchers,
respectively, and a second portion located between the opposite
ends of the first portion, wherein the second portion extends
substantially laterally from the first portion to define a widened
area of the support upon which the comestible fluid container
rests.
[0017] Further features and a better understanding of the present
invention, together with the organization and manner of operation
thereof, will become apparent from the following detailed
description of the invention when taken in conjunction with the

DETAILED DESCRIPTION
[0028] An embodiment of a comestible fluid container rack according
to the present invention is illustrated in FIGS. 1 and 2A. The
illustrated rack (indicated generally at 10) is adapted for holding
bag-in-box type comestible fluid containers. Bag-in-box comestible
fluid containers typically have a port to which a conduit 64 can be
releasably connected and through which comestible fluid can be
pumped, drained, or otherwise removed from the container. Although
the port in such containers is typically located near the bottom of
the container, the port can be in any location on the container
depending at least in part upon the manner in which comestible
fluid is removed from the container. Bag-in-box comestible fluid
containers are well-known to those in the art and are not therefore
described further herein.
[0029] Although the illustrated embodiment of the rack 10 is
adapted for holding bag-in-box type comestible fluid containers, it
will be appreciated that the rack 10 can be adapted for holding any
other type of comestible fluid container--such as in a manner
enabling comestible fluid to be dispensed from the comestible fluid
container while on the rack 10. Other types of comestible fluid
containers include without limitation bottles, jugs, boxes,
hoppers, bags, crates (e.g., lined or otherwise adapted to hold
fluid), kegs, barrels, and the like.
[0030] The comestible fluid containers used in the rack of the
present invention can hold any type of comestible fluid desired. By
way of example only, such comestible fluids include syrups or other
concentrated fluids for making carbonated beverages, non-carbonated
beverages such as lemonade, tea, fruit juices, milk, and the like,
condiments, and flowable food products.
[0031] For ease of description, the following text is with
reference to a rack 10 adapted for holding bag-in-box syrup
containers for making sodas, to syrup dispensing system components,
and to equipment used to connect and mount such components.
However, it should be noted that the present invention can be
employed to hold any other type of comestible fluid container
holding any other type of comestible fluid, can be employed in
connection with the dispense of any other type of comestible fluid,
and can be employed to connect and mount components of any other
type of comestible fluid dispensing system.
[0032] The comestible fluid dispensing system illustrated in FIGS.
1 and 2A is comprised of multiple rack modules 12. Each rack module
12 includes three portions: first and second end portions 14, 16
and a center portion 18 connecting the first and second end
portions. Each end portion 14, 16 includes two vertical supports
20, a rail 22 extending between and connecting the vertical
supports 20, and two stretchers 24, 26 extending laterally from the
vertical supports 20. A support 28 is connected to at least one
(and in the case of the illustrated embodiment, both) of the
stretchers 24, 26 of each end portion 14, 16, and spans the
distance between the stretchers 24, 26.
[0033] The rails 22 can take any shape and size desired, and are
illustrated as elongated plates in FIGS. 1 and 2A. By way of
example only, the rails 22 can be rods, bars, tubes, angles, or
sheets of material. The rails 22 can extend generally horizontally
between the vertical supports 20 as shown in FIGS. 1 and 2A or can
extend in any other manner, such as diagonally. If desired, each
rack module 12 can have a single rail on each end of the rack
module 12 as shown in FIGS. 1 and 2A, or can instead have two or
more rails on each end. In still other embodiments, no rails 22 are
employed (in which cases the vertical supports 20 of each end
portion 14, 16 can be connected together in another manner, such as
by elements coupled to and extending between front and rear
stretchers 24, 26 or other stretcher elements of the rack 10). The
rails 22 in the illustrated embodiment are welded to the vertical
supports 20. However, the rails 22 can instead be connected to the
vertical supports 20 in any other manner, such as by screws, bolts,
pins, rivets and other conventional fasteners, by brazing or gluing
the rails 22 to the vertical supports 20, by straps, inter-engaging
or snap-fitting fingers, tabs, or other elements on the rails
and/or vertical supports 20, and the like.
[0034] Although each rack module 12 illustrated in FIGS. 1 and 2A
have four vertical supports 20 located at the corners of the rack
module 12, it should be noted that each rack module 12 can have
other numbers of vertical supports 20 arranged in any other manner
desired. By way of example only, three or more vertical supports 20
(not shown) can be located on either side of the rack module 12. As
another example, the vertical supports 20 can take the form of
plates or panels (e.g., a plate or panel on each end of the rack
module 12), frames, or other elements or structure providing
support for the stretchers 24, 26 on both ends of the rack module
12.
[0035] In some embodiments such as that shown in FIGS. 1 and 2A,
the stretchers 24, 26 of each end portion 14, 16 are vertically
offset such that the supports 28 slope downward from the rear
stretcher 26 to the front stretcher 24. Such a slope can promote
drainage of syrup in bag-in-box containers having a tap at the
lowest point on the front of the container. As used herein, the
terms "front", "rear", "left", and "right" are employed to describe
the orientation of elements in the illustrated embodiment of FIGS.
1, 2A, and 5. However, because the rack 10 of the present invention
can be oriented in any manner desired, these terms are not intended
to be limiting with regard to the manner in which the rack 10 of
the present invention is positioned in any environment.
[0036] The supports 28 (if employed) can slope downward toward the
front of the rack 10 in any amount desired. In some embodiments,
the front and rear stretchers 24, 26 are vertically offset an
amount sufficient to provide a 5-15 degree downward slope to the
supports 28. In other embodiments, the front and rear stretchers
24, 26 are vertically offset an amount sufficient to provide a 7-12
degree downward slope to the supports 28. In still other
embodiments, the front and rear stretchers 24, 26 are vertically
offset an amount sufficient to provide a 9 degree downward slope to
the supports 28. As an alternative or in addition to the use of
vertically-offset stretchers 24, 26 as described above, a tilt can
be provided to comestible fluid containers on the supports 28 by
the shape of the supports 28 (as will be described in greater
detail below).
[0037] With continued reference to the illustrated embodiment of
FIGS. 1 and 2A, the center portion 18 of each rack module 12
includes a front stretcher 30, a rear stretcher 32, and a support
28 spanning the distance between and coupled to the front and rear
stretchers 30, 32. In other embodiments, two or more supports 28
can extend between and be coupled to the front and rear stretchers
30, 32. Such additional supports 28 can be employed to increase the
storage capacity of the rack module 12.
[0038] With particular reference to FIG. 2A, each rack module 12
can be assembled by arranging the front and rear stretchers 24, 26
of the end portions 14, 16 with the front and rear stretchers 30,
32 of the center portion 18. In the illustrated embodiment, the
front and rear stretchers 24, 26 of the end portions 14, 16 are
made of tubular material enabling the front and rear stretchers 30,
32 of the center portion 18 to be received therein in a telescoping
relationship. In this manner, the end portions 14, 16 of each rack
module 12 are slidable with respect to the center portion 18,
enabling a user to change the length of the rack module 12 (between
the end portions 14, 16). Such adjustability enables a user to
adjust the rack modules 12 (and therefore, the rack 10) to accept
different numbers, different sizes, and/or different arrangements
of syrup containers. Provided that the end portions 14, 16 of the
rack module 12 are separated a sufficient distance from one
another, such adjustability can also enable the center portion 18
(and any supports 28 thereon) to be moved to different positions
with respect to the end portions 14, 16. This adjustability of the
center portion 18 enables a user to adjust the rack modules 12 to
support different numbers, different sizes, and different
arrangements of syrup containers.
[0039] It will be appreciated by one skilled in the art that the
stretchers 24, 26 of the first and second end portions 14, 16 can
telescope with respect to the stretchers 30, 32 of the center
portion 18 in a number of different manners. Specifically, the
manner in which one element "telescopes" with respect to another
does not indicate or imply any particular cross-sectional shape of
the elements, nor that one element must be completely surround
another. As used herein and in the appended claims, the term
"telescope" in its various forms means that one element (e.g., a
stretcher 24, 26, 30, 32) is axially positionable with respect to
another and that the elements are coupled together (a) by virtue of
one being partially or entirely received within the other and/or
(b) by virtue of another connection between the elements (e.g., one
or more fasteners or other structure connecting one of the elements
to the other).
[0040] In some embodiments, the stretchers 30, 32 of the center
portion 18 and the stretchers 24, 26 of the end portions have a
clearance fit or have a sufficiently loose fit to enable the
stretchers 30, 32 and 24, 26 to freely move with respect to one
another. Although in some embodiments the stretchers 24, 26, 30, 32
can be freely removed from one another, in other embodiments the
stretchers 24, 26, 30, 32 can be provided with stops that prevent
the center portion stretchers 30, 32 from being removed from the
end portion stretchers 24, 26 or from being extended from the end
portion stretchers 24, 26 over a desired amount. The stops can take
any form desired, such as an internal rib, flange, or pin on each
end portion stretcher 24, 26 that engages an external flange, pin,
or other protrusion on a mating center portion stretcher 30, 32
when the center portion stretcher 30, 32 has been extended from the
end portion stretcher 24, 26 a sufficient amount. As another
example, the stops can be defined by a retractable protrusion
extending from each center portion stretcher 30, 32 into engagement
with a groove, recess, or other aperture in a mating end portion
stretcher 24, 26 (or vice versa) when the center portion stretcher
30, 32 has been pulled from the mating end portion stretcher 24, 26
a sufficient amount.
[0041] With regard to two or more elements in telescoping
relationship with one another, one having skill in the art will
appreciate that a number of different manners, elements, and
structure exist for preventing the complete removal of one
telescoping element from another or for limiting the amount that
one telescoping element can extend from another. Any such manner,
elements, and structure can be employed to limit the extension of
the center portion stretchers 30, 32 from the end portion
stretchers 24, 26 and fall within the spirit and scope of the
present invention.
[0042] In some embodiments such as that shown in FIGS. 1 and 2A,
the center portion stretchers 30, 32 are received within the end
portion stretchers 24, 26 with a snug fit or a fit that otherwise
provides some resistance against free movement of the center
portion stretchers 30, 32 with respect to the end portion
stretchers 24, 26. In this manner, the stretchers 24, 26, 30, 32
can be moved under force to desired positions with respect to one
another and can remain in such positions until forced therefrom.
This adjustability permits an assembler or other user to adjust the
rack modules 12 to two or more desired lengths (and in some cases a
range of desired lengths) as needed or desired to accommodate
different numbers and/or sizes of comestible fluid containers.
[0043] Other manners of retaining a rack module 12 at a desired
length by releasably retaining the center portion stretchers 30, 32
in respective positions relative to the end portion stretchers 24,
26. By way of example only, resiliently biased detents located on
the center portion stretchers 30, 32 and/or on the end portion
stretchers 24, 26 can extend into grooves, recesses, or other
apertures in the end portion stretchers 24, 26 and/or center
portion stretchers 30, 32, respectively. Any conventional detent
element or device used to releasably secure telescoping poles or
tubes in a desired position can be employed as desired. In some
embodiments, the center portion stretchers 30, 32 can be releasably
secured in two or more different positions with respect to the
stretchers 24, 26 of either or both end portions 14, 16. For
example, the center portion stretchers 30, 32 can be telescoped
with respect to the end portion stretchers 24, 26 to selectively
engage resiliently biased detents with one of two or more grooves,
recesses, or other apertures. Any conventional detent element or
device used to releasably secure telescoping poles or tubes in one
of two or more desired positions can be employed as desired.
[0044] As another example, the center portion stretchers 30, 32 and
end portion stretchers 24, 26 can each be provided with one or more
apertures through which a pin, screw, key, or other element can be
passed to secure the center portion stretchers 30, 32 in position
with respect to the end portion stretchers 24, 26. Specifically,
the center portion stretchers 30, 32 can be telescoped with respect
to the end portion stretchers 24, 26 to one or more positions in
which one or more apertures in both types of stretchers 24, 26, 30,
32 are aligned. At such positions, a pin, screw, key, or other
element can be passed through the aligned apertures to retain the
stretchers 24, 26, 30, 32 in their relative positions. In this
manner, the portions 14, 16, 18 of the rack module 12 can be
secured together in a particular manner (e.g., at a particular
length). In those cases in which stretcher apertures are aligned in
two or more different relative positions of the stretchers 24, 26,
30, 32, such apertures also enable the rack modules 12 to be
adjustable to different lengths.
[0045] Still other manners exist for securing a first element in
one or more different positions with respect to a second element in
telescoping relationship with the first element. For example, the
exterior element can have a longitudinal groove through which a
fastener (e.g., a bolt or screw) passes that can be tightened to
secure the telescoping elements in different positions with respect
to one another, the interior element can be threaded into the
exterior element, the elements can be shaped so that one moves
freely within the other in at least one rotational orientation of
the elements but is resistant to axial movement when rotated to a
different rotational orientation (e.g., telescoping oval tubes),
and the like. All such manners for securing one telescoping element
in different axial positions with respect to another can be
employed in the stretchers 24, 26, 30, 32 described above, and
falls within the spirit and scope of the present invention.
[0046] The rack modules 12 in the illustrated embodiment of FIGS. 1
and 2A each have center portion stretchers 30, 32, flanked by and
telescoping within end portion stretchers 24, 26 as described in
greater detail above. However, it will be appreciated that the
length of the rack modules 12 can be adjusted in other manners
using different elements and structure. By way of example only, the
center portion stretchers 30, 32 can be dimensioned to receive the
end portion stretchers 24, 26 rather than to be received within the
end portion stretchers 24, 26 as described above. Alternatively,
one end of the center portion stretchers 30, 32 can be dimensioned
to be received within the stretchers 24, 26 of one end portion 14
while the other end of the center portion stretchers 30, 32 can be
dimensioned to receive the stretchers 24, 26 of the other end
portion 16. As another example, the center portion stretchers 30,
32 can be connected to telescope only with respect to the
stretchers 24, 26 of one of the end portions 14, 16 (while being
rigidly connected to the stretchers 24, 26 of the other end portion
16, 14). Other embodiments of the present invention have no center
portion 18, and instead employ stretchers 24, 26 of one end portion
14, 16 that telescope within stretchers 26, 24 of another end
portion 16, 14 in any manner (such as those described above). In
still other embodiments, the end portions 14, 16 of the rack
modules 12 can be connected by stretcher assemblies each having
four or more telescoping stretchers (rather than the stretcher
assemblies described above in which each stretcher assembly is
defined by two end portion stretchers 24, 26 and one center portion
stretcher 30, 32. Any of these types of telescoping connections
between the end portions 14, 16 of the rack modules 12 can employ
any of the elements and features described above in order to secure
the end portions 14, 16 in desired relative positions (in an
adjustable or non-adjustable manner).
[0047] In some embodiments, it may be desirable to provide
additional structural stability to the rack modules 12 by
connecting the front stretcher 24, 30 to the rear stretchers 26, 32
with beams, tubes, rods, bars, or other elements. Such elements can
be connected to the stretchers 24, 26, 30, 32 in any manner, such
as by welding, brazing, or gluing, by fasteners (e.g., clips,
screws, clamps, rivets, and the like connecting the elements to the
stretchers 24, 26, 30, 32), or by engagement with the stretchers
24, 26, 30, 32 (e.g., the ends of the elements being inserted into
apertures in the stretchers 24, 26, 30, 32, being snap-fitted to
the stretchers 24, 26, 30, 32, and the like).
[0048] With continued reference to FIGS. 1 and 2A each rack module
12 has two sets of stretchers 24, 26, 30, 32 (i.e., front and
rear). However, it will be appreciated that each module 12 can have
any number of stretcher sets located in different areas of the
module 12. For example, three or four sets of stretchers 24, 26,
30, 32 can laterally extend between the vertical supports 20 of
each end portion 14, 16. The sets of stretchers 26, 26, 30, 32 in
each module 12 can be located in any position or positions between
the top and bottom of each module 12 and between the front and rear
of each module 12 as desired.
[0049] The vertical supports 20 and the stretchers 24, 26, 30, 32
of the modules 12 illustrated in FIGS. 1 and 2A are made of hollow
tubing having a square cross sectional shape. However, the vertical
supports 20 can have any solid or hollow cross-sectional shape.
Similarly, the stretchers 24, 26, 30, 32 can have any
cross-sectional shape desired, limited only by the ability of the
stretchers 24, 26, 30, 32 to telescope as described above. In this
regard, the center portion stretchers 30, 32 in FIGS. 1 and 2A need
not necessarily be hollow to perform their telescoping functions.
In those embodiments of the present invention in which the
stretchers 24, 26, 30, 32 do not need to telescope (described in
greater detail below), the stretchers 24, 26, 30, 32 can take any
form desired.
[0050] As just indicated, the stretchers 24, 26, 30, 32 of the rack
modules 12 need not necessarily be in telescoping relationship with
one another as described above. In particular, in some embodiments
the end portion stretchers 24, 26 are adjustably coupled together
or to center portion stretchers 30, 32 without a telescoping
relationship. For example, the stretchers 24, 26, 30, 32 can be
beams, bars, or other elements each having one or more apertures
therethrough. When the stretchers 24, 26 of one end portion 14 are
brought to positions adjacent to the stretchers 30, 32 of the
center portion 18, the apertures in the end portion stretchers 24,
26 can be aligned with the apertures in the center portion
stretchers 30, 32, after which time pins, fasteners, keys, or other
elements can be passed through the aligned apertures to connect the
stretchers 24, 26 of the end portion 14 to those of the center
portion 18. Connection of the center portion stretchers 30, 32 to
the stretchers 24, 26 of the other end portion 16 can be made in a
similar fashion. In cases where multiple apertures are employed in
some or all of the stretchers 24, 26, 30, 32, such an arrangement
permits adjustability of the length of the rack module 12. Other
manners of adjustably or non-adjustably connecting the end portion
stretchers 24, 26 to the center portion stretchers 30, 32 without a
telescoping relationship are possible and fall within the spirit
and scope of the present invention.
[0051] As mentioned above, each rack module 12 illustrated in FIGS.
1 and 2A has supports 28 extending between the front and rear
stretchers 24, 30; 26, 32. Although some embodiments of the present
invention employ rack modules 12 having no supports 28, such
supports 28 can provide additional strength to the rack modules 12
and can help to support comestible fluid containers in the rack
modules 12. Each rack module 12 can have any number of supports 28
located in any position along the length of the rack module 12. In
the illustrated embodiment of FIGS. 1 and 2A, a support extends
between the stretchers 24, 26 of each end portion 14, 16 and
between the stretchers 30, 32 of the center portion 18. Other
embodiments of the present invention can employ any combination of
these supports 28, such as supports 28 only on the end portion
stretchers 24, 26, one or more supports only on the center portion
stretchers 30, 32, and the like.
[0052] Each support 28 in the illustrated embodiment includes a
wire frame shaped to support the underside of a bag-in-box type
comestible fluid container. Alternatively, the supports 28 can take
other forms capable of performing the same function, such as one or
more rods, plates, bars, beams, tubes, or other elements extending
between the front and rear stretchers 24, 30 and 26, 32.
[0053] In some embodiments, some or all of the supports 28 are
provided with one or more conduit braces 34 for holding and/or
supporting conduits 64 running in the rack 10. The conduit braces
34 can take a number of different forms each capable of performing
either or both of these functions. In the embodiment illustrated in
FIGS. 1 and 2A for example, each support 28 has two elongated loops
36 through which comestible fluid conduits 64 can be passed as
shown in FIG. 5. The conduit braces 34 (where employed) can be used
to neatly secure conduit 64 therethrough, thereby eliminating
additional hardware required to organize and secure the conduit
64.
[0054] The elongated loops 36 in the embodiment of FIGS. 1 and 2A
are defined by part of the wire frame of the supports 28, although
this is not necessarily the case. In other embodiments, elements
can be connected to the supports 28 in any manner to at least
partially define the loops 36 or other conduit brace structure. For
example, wire, rods, bars, and other elements can be coupled to the
supports 28 by welding, brazing, gluing, by one or more
conventional fasteners (e.g., clamps, straps, ties, threaded
fasteners, and the like). Accordingly, the supports 28 can have
elements or structure for holding and/or retaining comestible fluid
lines in the rack 10, such elements being integral with respect to
the supports 28 or separate elements coupled to the supports 28.
Although the conduit braces 34 can take the form of loops as
described above, other shapes of the conduit braces 34 are
possible, including without limitation hooks, rings, lugs, fingers
and other extensions, and the like.
[0055] With continued reference to the conduit braces 34
illustrated in FIG. 1, some conduit braces 34 according to the
present invention are shaped to have one or more tapered ends. For
example, the conduit braces 34 in the illustrated embodiment are
loops having front and rear ends that are tapered (i.e., the
portions or surfaces of the conduit brace 34 through or in which
the comestible fluid conduits are held are disposed at an acute
angle with respect to one another). This conduit brace shape
enables a user to move a comestible fluid conduit within the
conduit brace 34 to a location at the taper in which the conduit
brace 34 grips the comestible fluid conduit. In some embodiments,
the amount of grip provided by the tapered portion(s) of the
conduit brace 34 is sufficient to retain the comestible fluid
conduit within the conduit brace 34 but is not sufficient to
appreciably deform the comestible fluid line or to constrict flow
therethrough. Although the tapered portions of the conduit braces
34 illustrated in FIGS. 1, 2A, and 5 are shown in a wire-type
support 28, it should be noted that tapered portions or surfaces
can be employed in any other type of support 28 (including the
alternative supports 28 described herein) to perform any of the
same functions discussed above. In addition, the tapered portion(s)
of the conduit brace 34 need not necessarily be located at an end
of the conduit brace 34. The tapered portions can each be defined
by one or more bumps, bosses, ramps, ribs, or other protrusions of
the conduit brace 34 and/or support 28 and upon which a comestible
fluid conduit can be moved to wedge or grip the comestible fluid
conduit in position with respect to the support 28.
[0056] In some embodiments, the conduit braces 34 can be movably
attached to the supports 28 and/or to the stretchers 24, 26, 30, 32
in order to enable easier installation and routing of conduits 64
therethrough. By way of example only, the conduit braces 34 can be
pivotably attached to the supports 28 or can be releasably attached
to the supports 28 in any manner so that the conduit braces 34 can
be opened and closed during conduit 64 installation. Any latching
or mating engagement of the conduit braces 34 to the supports 28
can be employed to secure the conduit braces 34 in closed positions
on the supports 28.
[0057] The supports 28 in the embodiment of the present invention
illustrated in FIGS. 1 and 2A are shaped to prevent or help prevent
the comestible fluid containers from falling off of the rack 10.
Although the stretchers 24, 26, 30, 32 can be positioned (and in
some cases, shaped) to perform this function without the assistance
from the supports 28, the supports 28 can provide a more stable
foundation for the comestible fluid containers. Each support can be
substantially flat or can take any other shape adapted to perform
the function of supporting the comestible fluid containers. In
those cases where the comestible fluid containers are to be
supported in a tilted orientation, the supports 28 can have a stop,
ledge, rib, protrusion, or can otherwise be shaped to prevent the
comestible fluid containers from sliding off the lower end of the
supports 28. For example, each support 28 illustrated in FIGS. 1
and 2A has stops 38 at the front lower end thereof to prevent the
bag-in-box containers from sliding forwardly off of the rack 10. In
some embodiments, the supports 28 can be shaped to tilt the
comestible fluid containers if desired, such as ramp or
wedge-shaped supports 28, supports having one or more elevated
points (such as at the rear of each support), and the like.
Supports 28 having such shapes can be employed as an alternative to
or in addition to offset front and rear stretchers 24, 26, 30, 32
as described above.
[0058] Supports 28 can be located in any position or positions
between the vertical supports 20, and need not necessarily be
located on the front and rear stretchers 24, 26 of either or both
end portions 14, 16 or on the front and rear stretchers 30, 32 of
the center portion 18. Any arrangement of supports 28 on any of the
front and rear stretchers 24, 30; 26, 32 is possible.
[0059] The supports 28 in the illustrated embodiment of FIGS. 1 and
2A are attached to the stretchers 24, 26, 30, 32 by welds. However,
the supports 28 can be attached to the stretchers 24, 26, 30, 32 in
any other releasable or non-releasable manner, including without
limitation by brazing, clamps, gluing, screws and other threaded
fasteners, rivets, pins, snap-fitting, and the like. In this
regard, it may be desirable to move the supports 28 to different
positions with respect to the stretchers 24, 26, 30, 32 as the need
may arise, such as to support comestible fluid containers in
different locations along the length of the rack, to provide
different comestible fluid container spacing, and the like. Such
flexibility is available to some degree by the attachment of
supports 28 to telescoping stretchers 24, 26, 30, 32 as described
above or to stretchers 24, 26, 30, 32 that are otherwise movable to
different positions with respect to one another.
[0060] However, increased flexibility is enabled by permitting
releasable attachment of the supports 28 to different locations on
the stretchers 24, 26, 30, 32. In some cases, the supports 28 are
releasably attached to the front and rear stretchers 24, 26, 30,
32, while in other cases the supports 28 are releasably attached
only to the front stretchers 24, 30 or only to the rear stretchers
26, 32 while being unattached to the other stretchers. One or more
of the supports 28 can be releasably attached to the stretchers 24,
26, 30, 32 in a number of different manners, such as by receiving
the ends of the supports within apertures in the stretchers 24, 26,
30, 32, by receiving legs, pins, fingers, tabs, or other extensions
of the supports 28 in apertures in the stretchers 24, 26, 30, 32,
by strapping or tying the supports 28 to the stretchers 24, 26, 30,
32, by magnet sets attached in any conventional manner to the
supports 28 and to the stretchers 24, 26, 30, 32, by clamps or
clips on the supports 28 and/or stretchers 24, 26, 30, 32, by
screws, pins, or other releasable fasteners tightenable to secure
the supports 28 to the stretchers 24, 26, 30, 32, and the like.
Still other manners of releasably connecting the supports to one or
more positions on the stretchers 24, 26, 30, 32 are possible, each
of which falls within the spirit and scope of the present
invention. In some embodiments, such manners of connection enable
the user to position and secure the supports 28 in two or more
locations (and in some cases, a range of locations) along the
stretchers 24, 26, 30, 32.
[0061] Whether the position of supports 28 on the rack module 12
are adjustable by virtue of the telescoping relationship of the
stretchers 24, 26, 30, 32 or by the ability to releasably attach
the supports 28 in different positions on the stretchers 24, 26,
30, 32 as described above, in some embodiments the supports 28 are
movable in the rack module 12 to different lateral positions to
provide support as needed by comestible fluid containers in the
rack module 12. By way of example only, the center support 28 in
FIGS. 1, 2A, and 5 can be laterally adjustable to the left and/or
right in order to support comestible fluid containers having
different sizes and weights in the rack module 12. In some cases,
(such as when some part or all of the support 28 has a relatively
wide shape), one or more supports 28 can be shaped to move under or
over one or more adjacent supports 28 on the rack module 12 as
needed or desired. For example, if the supports 28 illustrated in
FIGS. 1, 2A, and 5 were shaped to have laterally-extending wings or
other portions providing a wider base upon which comestible fluid
container(s) can rest, such wings or other portions could be shaped
to slide under or over adjacent supports 28 on the rack module 12
(see FIGS. 6-8).
[0062] Some embodiments of the present invention provide the
ability to expand the rack 10 by stacking rack modules 12 on top of
one another. Although the rack modules 12 can be stacked without
connecting the rack modules 12 together, in some embodiments the
rack modules 12 are connected for increased rack stability and
strength. Stacked rack modules 12 can be attached to one another in
a number of different manners, one of which is illustrated in FIGS.
1 and 2A. Specifically, couplings 40 are employed to connect the
vertical supports 20 of one rack module 12 to the vertical supports
12 of another. The couplings can be made of any sufficiently
resilient and strong material (such as plastic, rubber, nylon,
elastomeric material, metal, composites, wood, and the like). With
particular reference to FIG. 2B, the couplings 40 are shaped to be
received within the hollow tubular ends of the vertical supports
12, thereby connecting the vertical supports 12 to one another.
Each coupling 40 has stems 42 with outer dimensions sized to
provide at least a snug fit with the vertical supports 20 and a
center bushing 44 between the stems. In some cases, the coupling 40
is made at least partially of resilient material such as rubber,
urethane, nylon, or other elastomeric material in order to provide
an interference fit between the stems 42 and the hollow vertical
supports 20 of the rack modules 12, thereby interlocking vertically
adjacent rack modules 12. The resilient couplings 40 allow the rack
modules 12 to be stacked upon one another to vertically expand the
rack. The couplings 40 can be releasably attached to both the
bottom and top of each rack module 12 or can be permanently
attached to either the bottom or top ends of the vertical supports
20.
[0063] In some embodiments, the couplings 40 are defined by ends of
the vertical supports 20 shaped to mate with the ends of vertical
supports 20 on another rack module 12 (e.g., reduced ends on the
top or bottom of the vertical supports 20 mating with hollow ends
of vertical supports 20 on another rack module 12, flared ends on
the top or bottom of the vertical supports 20 mating with ends of
the vertical supports 20 on another rack module 12, and the like).
In other embodiments, the couplings 40 are elements that are
received around one or both ends of adjacent vertical supports 20
in order to connect vertically adjacent rack modules 12. For
example, sleeves or sockets can be connected to the ends of
adjacent vertical supports 20 in order to connect the supports 20
together.
[0064] In still other embodiments, the couplings 40 can be flanges,
collars, tabs, or other extensions on the upper and lower ends of
the vertical supports 20. The flanges, collars, tabs, or other
extensions of one module can be permanently or releasably connected
to those of another in order to connect the vertical supports 20
together, such as by bolts, screws, pins, or other conventional
fasteners passed through aligned apertures in the flanges, collars,
tabs, or other extensions. Alternatively, adjacent vertical
supports 20 can be connected together by clasps or latches on the
ends of the vertical supports 20, conventional fasteners passed
through or around the adjacent ends of the vertical supports 20,
snap-fitting the vertical support ends of one rack module 12 into
those of another, detents (spring-loaded or otherwise) on the
vertical support ends of one rack module 12 engaging those of
another, braces spanning the joint between adjacent vertical
supports 20, and the like.
[0065] As shown in FIG. 5, the couplings 40 can enable the quick
assembly and disassembly of a rack 10 comprised of multiple rack
modules 12. In some embodiments, the couplings 40 allow the rack 10
to be disassembled into individual rack modules 12 for easy
transport, with each rack module 12 capable of supporting one or
more comestible fluid containers and fluid dispensing components
(including conduits 64) during transport. Likewise, after
transport, the couplings 40 can permit the user to quickly
reassemble the rack 10. Depending at least partially upon the
strength of the vertical supports 20, any number of rack modules 12
can be stacked upon one another to provide significant
expandability of the rack 10 according to the present invention.
However, in some embodiments of the present invention, the rack 10
is defined by a single rack module 12.
[0066] If desired, the top rack module 12 of a rack 10 can be used
to support other structure, such as an additional shelf, other
equipment, and the like. By way of example only, a telescoping
shelf (i.e., having one or more leaves telescoping with respect to
one another) can be stacked upon the vertical supports 20 of the
uppermost rack module 12, and can be connected thereto in any
conventional manner. Any type of telescoping or expandable shelf
can be employed, such as a shelf having one or more panels
laterally slidable into one or more tubular panels, one or more
panels having a C-shaped cross-section laterally slidable over one
or more other panels, and the like. Any such telescoping or
expandable shelf can be used and can be adjustable to a length
corresponding to the length of the rack 10.
[0067] With reference now to FIG. 4, one or more rails 22 of the
rack 10 can be employed not only to provide structural strength and
stability to the rack 10, but also as a mounting location to which
comestible fluid dispensing components can be permanently or
releasably mounted to the rack 10. Such comestible fluid dispensing
components include without limitation, pumps, ASVs and other
valves, filters, regulators, and fluid treatment devices. Any
number and combination of such comestible fluid dispensing
components can be permanently or releasably mounted to the rail
22.
[0068] The rails 22 can be located in any vertical position on one
or more rack modules 12 of the rack 10. However, it is often
desirable to connect one or more rails 22 of a rack module 12 to
the vertical supports 28 at a higher elevation than the outlets of
the comestible fluid containers on the rack module 12. In some
cases, some comestible fluid dispensing components operate at less
than optimal performance or perform poorly when positioned at an
elevation that is the same or lower than the dispensing outlet of a
connected comestible fluid container. For example, positioning a
pump at a lower elevation than the outlet of a bag-in-box
comestible fluid container connected thereto can cause air to be
entrained in a conduit extending between the pump and the
comestible fluid container. Some embodiments of the present
invention can address this and other dispensing system performance
problems by positioning the rail 22 at a higher elevation than the
dispensing outlets of comestible fluid containers connected to
pumps and other components on the rail 22. By employing a rail 22
positioned in this manner, the need for an assembler or user to
quickly find a suitable mounting location for one or several
condiment dispensing system components at suitable elevations
(often a difficult task using conventional equipment) is met.
[0069] Comestible fluid dispensing components can be mounted
anywhere upon the rail 22 in a number of different manners, such as
by securing the components to the rail using one or more screws,
bolts, rivets, pins, and other conventional fasteners, by welds,
brazing, or gluing the components to the rail 22, by straps,
inter-engaging or snap-fitting fingers, tabs, or other elements on
the rail 22 and/or comestible fluid dispensing components, and the
like. However, in some embodiments, comestible fluid dispensing
components are mounted to the rail 22 by a bracket 46 as best shown
in FIGS. 3 and 4. The bracket 46 can have any shape desired, and in
some cases is defined by a generally planar body having one or more
extensions used for connecting a comestible fluid dispensing
component 48 thereto and/or for manipulating the bracket 46. By way
of example only, the comestible fluid dispensing components 48
illustrated in FIGS. 4 and 5 are pumps (e.g., "Heavy Duty
Advantage" Bag-In-Box gas pump manufactured by SHURflo, Inc.).
[0070] With particular reference to FIG. 3, the exemplary
illustrated bracket 46 has a pair of raised bosses 50, a pair of
fingers 52, a lever 54, and an aperture 56 in the lever 54 for
connecting the pump 48 shown in FIGS. 4 and 5 to the bracket 46. In
particular, the raised bosses 50 receive a rail or other protrusion
of the pump 48, the fingers 52 are received within apertures in the
pump, and the aperture 56 in the lever 54 receives a pin or other
protrusion on an end of the pump 48. As best shown in FIG. 4, this
arrangement of elements enables a user to connect the pump 48 to
the bracket 46 by snapping the pump 48 into the bracket 46 (which
can include pivoting the pump 48 into place on the bracket 46 as
shown in FIG. 4). To release the pump 48, the lever 54 is pressed
so that the pin or other protrusion on the end of the pump 48 is
released from the aperture 56 in the lever 54, thereby permitting
the pump 48 to be removed from the bracket 46.
[0071] Although the bracket 46 illustrated in FIGS. 3 and 4 has the
bosses 50, fingers 52, lever 54, and lever aperture 56 as just
described, it will be appreciated that the pump 48, other types of
pumps, and other comestible fluid dispensing components can be
releasably or permanently mounted to the bracket 46 in a number of
other manners employing a number of other features on the bracket
46. By way of example only, the bracket 46 can have one or more
pins that mate with apertures in the comestible fluid dispensing
component (and vice versa), can have one or more fingers, tabs,
flanges, or other extensions to which the comestible fluid
dispensing component can mate or otherwise be engaged, can have one
or more straps or other elongated elements that extend around any
part of the comestible fluid dispensing components, can have one or
more recesses shaped to receive part of the comestible fluid
dispensing components, can have one or more clips extending
therefrom for engagement with features on the comestible fluid
dispensing components 48, can engage the comestible fluid
dispensing component by a sliding or rotating engagement (e.g., via
inter-engaging teeth, flanges, pins, or other elements on the
bracket 46 and comestible fluid dispensing component), and the
like.
[0072] For example, a comestible fluid dispensing component 48 can
be mounted on the bracket 46 via apertures (e.g., holes, recesses,
grooves, slots, and the like) in the bracket 46. In the case of
comestible fluid dispensing components that do not employ a pin and
lever mounting configuration as illustrated in the figures, these
apertures can engage posts, pins, or other extensions (not shown)
on the comestible fluid dispensing component 48 in order to secure
the component 48 to the bracket 46.
[0073] In some embodiments, the bracket 46 has connection elements
or features for mounting two or more different types of comestible
fluid dispensing components on the same bracket 46, such as a pump
and an ASV, pumps having different shapes, sizes, dimensions, and
the like.
[0074] With continued reference to FIG. 4, the brackets 46 in the
illustrated embodiment are slidable to different positions along
the rail 22 by a sliding connection between the brackets 46 and the
rail 22. Specifically, one or more edges 58 of the bracket 46 are
dimensioned to be slidably received within one or more grooves 60
running along the rail 22. The grooves 60 can be defined in the
rail 60 in any manner, and in some cases (such as that shown in the
figures) are defined by elongated walls 62 in the rail 60. The
bracket 46 can be received within the groove(s) 60 with a clearance
fit or can be received with a snug fit permitting movement of the
bracket 46 along the rail 22 with sufficient force applied to the
bracket 46.
[0075] The brackets 46 in the illustrated embodiment of FIGS. 3-5
can be movable to any number of different positions along the rail
22. In some embodiments, the bracket 46 is movable to two or more
discrete positions on the rail 22, while in other embodiments the
bracket 46 is movable to any position within a range of positions
along the rail 22. The positions can be along the entire length or
substantially the entire length of the rail 22 or can be in only a
portion of the rail 22 as desired.
[0076] As an alternative to brackets 46 slidable within one or more
grooves 60 in the rail 22, the brackets 46 can be permanently or
releasably mounted in different positions along the rail 22 in
other manners. For example, in some embodiments the rails 22 have
two or more fasteners spaced apart along the rail 22 and that
extend into engagement with the bracket 46 in different positions
along the rail 22. As another example, the bracket 46 can be
provided with one or more releasable fasteners that can be
tightened to secure the bracket 46 in different locations along the
rail 22. In other embodiments, the bracket 46 can have flanges in
or between which is received the rail 22 (or part of the rail 22)
so that the bracket 46 can be slid or otherwise moved to different
locations along the rail 22. In still other embodiments, the
bracket 46 can have or be defined by an element partially or
entirely encircling the rail 22 and that can be slidable to
different positions along the rail 22. As another example, the rail
22 can have a raised rib that mates with a recess in the bracket 46
and along which the bracket 46 can be slid or otherwise moved to
different positions along the rail 22. Alternatively, the bracket
46 can have one or more ribs, fingers, pins, posts, flanges, bosses
or other extensions that are received within a groove or other
elongated aperture in the rail 22 permitting the bracket to be slid
or otherwise moved to different positions along the rail 22. In
other embodiments, the rail 22 can have two or more apertures along
its length that can be aligned with one or more apertures in the
bracket 46 (or vice versa) so that a pin, post, threaded fastener,
key, or other element can be received within aligned apertures to
secure the bracket 46 in different positions along the rail 22. One
having ordinary skill in the art will appreciate that still other
manners of mounting the bracket 46 in an adjustable manner along
the rail 22 are possible and fall within the spirit and scope of
the present invention.
[0077] The ability to adjust the position of the brackets 46 (and
therefore, the comestible fluid dispensing components) on the rail
22 provides a significant amount of flexibility for installers and
users to arrange comestible fluid dispensing components 48 as
desired on the rail 22. In this regard, the rail and bracket system
described above provides a number of advantages when employed on
the rack 10 illustrated in FIGS. 1, 2A, and 5, but provides similar
advantages when employed in other locations, such as to a wall, a
frame, shelving, or in any other location. Accordingly, the rail
and bracket system described above and illustrated in FIGS. 3 and 4
can be used in any other location desired, and need not necessarily
be employed in a comestible fluid container rack 10 as shown in
FIG. 5.
[0078] FIGS. 6-8 illustrate another exemplary embodiment of a
comestible fluid rack 100 according to the present invention. The
rack 100 is substantially similar to the rack 10 shown in FIGS.
1-5, with like elements labeled with like reference numerals in the
100 series of reference numbers. With the exception of mutual
inconsistencies in the racks 10, 100, reference is hereby made to
the description above relating to the rack embodiment of FIGS. 1-5
for further description of the various features and elements of the
rack 100 illustrated in FIGS. 6-8 and described below (as well as
the alternatives to such features and elements).
[0079] The exemplary rack 100 illustrated in FIGS. 6-8 includes two
end portions 114, 116, each having a support 128, and a center
portion 118 having another support 128. Each support 128 includes
at least one wing or other extension 121 coupled, although fewer
than all of the supports 128 can have such extensions 121, if
desired. In some embodiments, some or all of the extensions 121 can
extend laterally from their respective supports 128, such as in a
direction substantially perpendicular to the rest of the support
128 as shown in FIGS. 6-8 or at another angle with respect thereto.
In the illustrated construction, each extension 121 is positioned
generally on top of the remainder of the support 128, such that
comestible fluid containers can be supported on top of the
extensions 121 rather than on top of the support portions extending
toward the stretchers 124, 126, 130, 132. However, in other
embodiments, the extension 121 can be located below the rest of the
support 128 or can lie generally in the same plane as the rest of
the support 128 for any desired amount of direct contact with a
comestible fluid container thereon.
[0080] In some constructions of the rack 100, the support 128 and
the extension(s) 121 of the support can be separate components made
of the same or different material. By way of example only, the
extension(s) 121 can be made of metal wire joined in any of a
number of different ways (e.g., welding, brazing, bonding,
fastening, etc.) to the rest of the support 128, can be made of
fiberglass, plastic, composite, or other material joined to the
rest of the support 128 by adhesive or cohesive bonding material,
fasteners, etc., or can be made of any other material desired. In
other constructions, the support 128 can be integral with one or
more extensions 121, such that a first portion of the support 128
extends between stretchers 124, 126 or 130, 132 and one or more
extensions 121 of the support 128 extend substantially laterally
from the first portion to support one or more comestible fluid
containers thereon. Each support 128 in the exemplary embodiment of
FIGS. 6-8 has three extensions 121 coupled thereto and extending
laterally to both sides of a center support portion. In other
embodiments, however, the supports 128 can have fewer or more
extensions 121 extending to either or both sides of a central
support portion.
[0081] In those embodiments of the present invention in which one
or more supports 128 having one or more extensions 121 are
employed, the extensions 121 can be located anywhere along the
supports 128 desired (such as at the front, middle, and/or rear of
each support 128) and can be arranged on the supports 128 in any
manner desired (such extensions 121 that are equally spaced along
the supports 128, or extensions 121 arranged in other manners). In
some embodiments, the arrangement of extensions 121 on the supports
128 help to define desired relationships between adjacent supports
as will now be described.
[0082] In the illustrated construction of the rack 100 in FIGS.
6-8, the extensions 121 on a center support 128 of the rack 100
(e.g., on the center portion 118 of the rack 100) are offset with
respect to the extensions 121 of adjacent supports 128 (e.g., on
the end portions 114, 116 of the rack 100). In other words,
extensions 121 of adjacent supports 128 on the rack 100 are located
in different positions along the lengths of the supports 128. Such
a relationship between adjacent supports 128 allows the extensions
121 to nest within one another in an overlapping or non-overlapping
manner.
[0083] For example, when the stretchers 124, 126, 130, 132 are
telescoped with respect to one another in order to lengthen or
shorten the rack 100 as described in greater detail below, one or
more extensions 121 of a support 128 can be received in a nested
configuration with respect to one or more extensions 121 of an
adjacent support 128. In the illustrated exemplary embodiment in
which each support 128 has three extensions 121, two extensions 121
of each support 128 can each be received between a pair of
extensions 121 of an adjacent support 128, while one extension 121
of each support 128 is received adjacent an extension 121 at the
end of an adjacent support 128. In other embodiments, any number
(i.e., one or more) of extensions 121 of a support 128 can be
nested with respect to any number (i.e., one or more) of extensions
121 of an adjacent support 128. As used herein and in the appended
claims, the term "nested" means a relationship in which an
extension 121 of one support 128 is received between two extensions
121 of an adjacent support 128 or has a length that can be
positioned alongside a length of at least one extension 121 on an
adjacent support 128. In some embodiments, any number of extensions
121 on a first support 128 can be nested with respect to any number
of extensions 121 on supports 128 located to either or both sides
of the first support 128, and can be nested to any degree desired.
Such nesting can be accomplished by the use of telescoping
stretchers 124, 126, 130, 132 as described above, by moving
supports 128 along telescoping or non-telescoping stretchers 124,
126, 130, 132 in any other manner (as also described above), or by
placing and/or securing supports 128 on the rack 100 in such a
manner.
[0084] In addition to or as an alternative to nesting extensions
121 of adjacent supports 128 on a rack 100, one or more extensions
121 on a support 128 can be positioned to overlap one or more
adjacent supports 121. By way of example only, in some telescoping
positions of the exemplary rack 100 illustrated in FIGS. 6-8, the
extensions 121 of a support 128 overlap the center portion of at
least one adjacent support 128. As another example, in some
embodiments one or more extensions 121 of a support 128 can overlap
one or more extensions of an adjacent support 128. Any number of
extensions 121 can overlap any portion(s) of one or more adjacent
supports 128 to any degree and amount desired. In some embodiments,
the degree and amount of overlap can vary depending upon the
positions of adjacent supports 128 (whether adjustable in any
manner described above or otherwise). In the illustrated exemplary
embodiment, the extensions 121 of each support 128 can overlap
adjacent supports 128 to a greater or lesser extent based upon the
telescoping positions of the stretchers 124, 126, 130, 132.
[0085] It should be noted that the extension(s) 121 of a support
128 can be positioned on either side of another support 128 (e.g.,
on an upper or lower side of another support 128). As used herein
and in the appended claims, the terms "overlapping" and "overlap"
refer to both positions of an extension 121 (or other support
portion) with respect to another support.
[0086] In some embodiments, one or more supports 128 of the rack
100 can be positioned to nest with and overlap adjacent supports
128 (see, for example, the illustrated exemplary embodiment of
FIGS. 6-8. Either capability can permit the rack 100 to be
shortened or lengthened as desired while still providing a
relatively wide base upon which comestible fluid containers can be
supported. As best shown in FIGS. 7 and 8, the extensions 121 of
the support 128 on the left end portion 114 can nest with
extensions 121 of the support 128 on the center portion 118, while
the extensions 121 of the support 128 on the center portion 118 can
nest with extensions 121 of the support 128 on the left end portion
114. Alternatively or in addition, a similar relationship can exist
between the extensions 121 and supports 128 of the center and right
end portions 118, 116 depending at least in part upon the
telescoping positions of the stretchers 124, 126, 130, 132. Also,
the extensions 121 of the support 128 on the left end portion 114
can overlap the support 128 on the center portion 118, while the
extensions 121 of the support 128 on the center portion 118 can
overlap the support 128 on the left end portion 114 when the rack
100 is in a shortened configuration. Alternatively or in addition,
a similar relationship can exist between the extensions 121 and
supports 128 on the center and right end portions 118, 116
depending at least in part upon the telescoping positions of the
stretchers 124, 126, 130, 132. The extensions 121 can overlap
adjacent supports 128 by virtue of being located on top of the
center portions of the supports 128, such that telescoping movement
of the stretchers 124, 126, 130, 132 is not affected by an
extension 121 overlapping an adjacent support 128.
[0087] With reference to FIGS. 6 and 7, some embodiments of the
present invention provide a stop 138 for one or more of the
supports 128 on the rack 100. The stop 138, as previously described
with reference to the stops 38 of FIGS. 1, 2A, and 5, can be
positioned toward a lower portion of each support 128 such that the
stop 138 maintains a comestible fluid container on the rack 100
when the support 128 is tilted with respect to a horizontal plane.
The stop 138 can extend from the support 128 in a vertical
direction or can be tilted at an angle with respect to a vertical
direction while still performing this stopping function. Also, the
stop 138 can extend laterally from the support 128, if desired. In
some embodiments, the stop 138 can therefore be defined as another
extension 121 oriented as just described to stop a comestible fluid
container from sliding off the rack 100. In such embodiments, the
stop 138 can nest and overlap other stops 138 and/or extensions 121
in a manner described above with reference to the earlier-described
extensions 121 of the supports 128. As shown in FIGS. 7 and 8 for
example, when the rack 100 is in a shortened configuration, the
stops 138 can provide a barrier to any number of comestible fluid
containers supported on the extensions 121. In some embodiments,
this barrier can be gapless or can otherwise have no gaps
sufficiently large to permit a comestible fluid container to fall
from the rack 100.
[0088] In some embodiments, the stop 138 (if employed) can be
integral with the support 128, such as a stop 138 formed from the
same wire material as the center portion of the support 128 in the
exemplary embodiments of FIGS. 6-8. However, in other embodiments,
the stop 138 can be a separate component that is part of the
support 128, or can be another component that is not part of the
support 128. In such cases, the stop 138 can be permanently or
releasably joined to the support 128 in any manner (e.g., welding,
brazing, bonding, snap-fit, clipped, fastened, etc.). In the
illustrated embodiment of FIGS. 6-8 for example, the stops 138 are
separate components made from metal wire, and are welded to the
supports 128.
[0089] With reference to FIG. 6, in some embodiments one or more of
the stops 138 can include one or more conduit supports 135 shaped
to receive therethrough conduits (64, see FIG. 5) fluidly connected
to the comestible fluid containers. The conduit supports 135 can be
utilized to support conduits 64 toward the inlet ends of the
conduit 64 where the conduits 64 can be fluidly connected to the
comestible fluid containers. In the illustrated construction of the
stops 138, the conduit supports 135 are circular, and are integral
with the stops 138. However, in alternate constructions, the
conduit supports 135 can have any other shape capable of receiving
and otherwise supporting conduit 64, and need not necessarily be
integral with the stops 138 (e.g., conduit supports 135 connected
to the stops 138 in any of the manners described above with
reference to the relationship between the conduit braces 34 and the
supports 28 in the exemplary embodiment of FIGS. 1-5). Also,
alternate constructions of the stops 138 can employ more or less
than two conduit supports 135 as shown in FIGS. 6-8. The conduit
supports 135 can also be employed in addition to or separate from
the elongated loops 36 described above.
[0090] The embodiments described above and illustrated in the
figures are presented by way of example only and are not intended
as a limitation upon the concepts and principles of the present
invention. As such, it will be appreciated by one having ordinary
skill in the art that various changes in the elements and their
configuration and arrangement are possible without departing from
the spirit and scope of the present invention as set forth in the
appended claims. For example, the rack 10 illustrated in FIGS. 1,
2A, and 5 and the rack 100 illustrated in FIGS. 6-8 are adapted to
support bag-in-box type comestible fluid containers. However, the
rack 10, 100 of the present invention can be employed to support
other types of comestible fluid containers. In such cases, the
supports 28, 128 (if employed) can be adapted to support such other
types of comestible fluid containers. In the case of comestible
fluids stored in bags for example, the supports 28, 128 can take
the form of hangers suitable for suspending bags of comestible
fluid. In the case of kegs stored on their sides as another
example, the supports 28, 128 can be wider and/or can be shaped to
cradle the kegs. In short, the rack 10, 100 can be adapted to hold
any type of comestible fluid container desired, can have supports
28, 128 shaped to support different comestible fluid container
types, and can be provided with additional supporting elements as
needed for supporting the comestible fluid containers.
