Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is based on and claims priority from U.S.
Provisional Patent Application No. 61/143,862 filed on Jan. 12,
2009 and U.S. Provisional Patent Application No. 61/079,295 filed
on Jul. 9, 2008, both of which are incorporated herein by reference
in their entities for all purposes.
FIELD OF THE INVENTION
[0002] The present invention relates generally to the field of
merchandising systems. More particularly, the present invention
relates to a ventilated merchandising system which allows for
enhanced air circulation for items presented in a refrigerated
display case.
BACKGROUND
[0003] Merchandising systems for displaying products on shelves, in
cabinets or in display cases are frequently found in consumer
retail settings such as grocery stores, retail outlets and
department stores. In particular, merchandising systems are not
only used to conveniently store products, but are also used to
provide an effective and aesthetically pleasing display for
presenting the product to the consumer.
[0004] Display systems in refrigerated or freezer cases provide a
unique merchandising difficulty if they are replacing manufacturer
shelving units. In particular, cool air is pumped into the
refrigerated case from the top and front of each case, and display
systems located in the case obstruct the air flow patterns and
cause the cool air to be diverted from the products, and also
disrupt the balance of air inside the case and increase the amount
of cool air pumped in (and therefore increase the overall energy
needed to keep the case at the appropriate temperature). To help
improve air circulation, baffles may be added between the
merchandising displays in the case to aid in directing the cool air
to the products on the shelves above and below the baffles.
However, this is an added cost to the retailer, as they have to
purchase the baffles, install them, and lose valuable space in the
cases to allow room for the baffles between the displays. Baffles
currently used are often unsightly because they tend to droop
downwards from the point of attachment to the display grid, and
tend to be installed irregularly within a case and among adjacent
cases. Furthermore, the same types of shelves need to be installed
throughout a case in order for baffles placed among the shelves to
properly direct the cold air. The shelves must also be positioned
at the same linear height within the case. As such, retailers are
restricted to particular shelves and shelf configurations when
using the baffles. Additionally, the irregular and imprecise
placement of the baffles by the installers of the cooler units and
store employees often fails to direct airflow correctly around the
products.
[0005] There exist merchandising systems that allow for the
presentation of products on display shelves and grid systems, but
are not specifically designed for applications in refrigerator or
freezer units where proper air circulation is important for food
safety and preservation. Examples of such systems are disclosed in
U.S. Pat. No. 5,769,248, U.S. Pat. No. 5,855,283 and U.S. Pat. No.
6,886,699. For example, conventional automatic feed product
displays are configured to maintain the products to be displayed at
the front of the display, improving access to and visibility of
products to the consumer. The automatic feed displays eliminate a
customer having to reach into the display to access a product, and
may also provide a means for a portion of the display system to be
advanced forward for easy loading by the retailer. However,
conventional merchandising systems are not specifically designed
for refrigerator or freezer applications where the proper
circulation of cool air is essential to appropriately cool the
products on the shelves. Further, as discussed above, the use of
baffles is costly, unsightly, and inaccurate as a means of solving
the problem of circulation of air within a cooler unit.
[0006] As such, it is an object of the present invention to provide
a ventilated merchandising system for products displayed in
refrigerator or freezer cases, such that the merchandising system
is aesthetically pleasing, easy to install and versatile, and
effectively circulates cold air around the products without the
need for baffles.
SUMMARY OF THE INVENTION
[0007] The present invention provides a ventilated merchandising
system for products displayed in merchandise cooler units such as
refrigerator or freezer cases. One embodiment of a merchandising
system of the present invention includes a base member and a
platform coupled to the base member. A gap between the platform and
the base member allows air to flow between the platform and the
base member. One or more plenum plates can be coupled to the base
for directing air into the gap. The plenum plates can include
fingers for directing air into the gap, wherein the fingers may be
snap-fit on to vertical wires of a display grid. A pusher plate may
also be coupled to and movable along the platform for advancing
products along the platform.
[0008] Another embodiment of the present invention includes a base
member, a platform and one or more plenum plates. The platform is
coupled to the base member, moveable relative to the base member,
and formed to support products to be displayed. The one or more
plenum plates are coupled to the base member for directing air
between the platform and the base member. The platform can include
a separator coupled to the base member and a tray coupled to the
separator for supporting products for display. The separator is
preferably selectably slidable on the base member. The tray can
include a channel along which the pusher plate is moveable. One or
more arms may be coupled to the tray for supporting products. The
arms are preferably adjustable to accommodate products of varying
sizes. A front plate for retaining products can also be included,
where the front plate is coupled to the platform and includes one
or more vents to allow air to flow through the front plate.
[0009] The present invention also contemplates a baffle system that
may be coupled to a merchandising tray. The baffle system includes
a base member having a gap that allows air to flow through the base
member and one or more wings coupled to the base member, wherein
coupling the baffle system to a merchandising tray allows air to
flow beneath products supported on the merchandising tray. One or
more wing extensions may be moveably coupled to the wings, and one
or more plenum plates may be coupled to the base member for
directing air into the gap.
[0010] A method of distributing air flow within a merchandise
cooler unit having a plurality of merchandising systems installed
therein is also contemplated by the present invention. The method
includes the steps of: capturing cold air produced by the
merchandise cooler; directing the captured cold air into a gap
between a base member and a platform of each of the merchandising
systems in the merchandise cooler; and allowing the directed cold
air to flow through the gap between the base member and the
platform, thereby cooling products displayed on the merchandising
system.
[0011] It will be understood by those skilled in the art that one
or more aspects of this invention can meet certain objectives,
while one or more other aspects can lead to certain other
objectives. Other objects, features, benefits and advantages of the
present invention will be apparent in this summary and descriptions
of the preferred embodiments, and will be readily apparent to those
skilled in the art. Such objects, features, benefits and advantages
will be apparent from the above as taken in conjunction with the
accompanying figures and all reasonable inferences to be drawn
therefrom.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0070] One embodiment of a ventilated merchandising system 30 for
placement on a grid system 10 of a refrigerator or cooler case 20
is shown in the FIGS. 1-18. As seen in FIGS. 1-4, the system 30
includes a base member 40, separator portion 50 and tray 60. The
separator portion 50 and the tray 60 together form a platform
coupled to the base member 40 for supporting products to be
displayed. As seen best in FIG. 2, the separator 50 is coupled to
the base member 40 by flanges 41, 42 which fit into slots 51, 52 of
the separator 50. In one embodiment, the slots 51, 52 of the
separator 50 fit over the flanges 41, 42 so that the entire
separator 50 is slidably coupled to the base member 40. As seen in
FIG. 3, lips 53A, 53B, 54A 54B are located on the bottom of the
separator 50. These lips 53A, 53B, 54A 54B fit into a groove 48
coupled to a button 47 on the base 40 (other similar means of
releasably engaging the separator 50 to the base 40 could also be
used). In the first mode of operation, the display mode seen in
FIG. 1, the front lips 53A, 53B are fit into the groove 48. To
disengage the separator 50 and slide the separator 50 and tray 60
forward away from the rear edge 45 of the base 40 to the second
mode of operation, the loading mode seen in FIG. 6, the button 47
is pressed upward, causing the groove 48 to move downward away from
the separator 50 and moving the groove 48 away from the front lips
53A, 53B. This releases the separator 50 from the base 40 and
allows for the separator 50 (and tray 60 coupled to the separator
50) to be advanced away from the rear edge 45 of the base 40 so
that the tray 60 can be moved forward to allow easy loading of
products onto the tray 60. The rear lips 54A, 54B then engage with
the groove 48 to secure the separator 50 in the second position for
loading of the products. When the products have been loaded, the
release button 47 is again pressed upward, moving the groove 48
away from the rear apertures 54A, 54B so that the separator 50 can
be slid backward toward the rear edge 45 into the first position.
The groove 48 then engages again with the front apertures 53A, 53B
to secure the tray 60 with loaded products in the first display
position. As seen in an alternate embodiment in FIGS. 9A-9D, the
release mechanism may be located on the separator 50, and metal
supports 130 may be incorporated into the bottom of the separator
50 for added stability when separator 50 is pulled away from the
base member 40 for product loading.
[0071] Tray 60 is coupled to separator 50 by fitting front edge 63
of tray 60 into channels 55A, 55B of separator 50. In other
embodiments, tray 60 may be integrally formed with or rigidly
coupled to the separator 50. Separator 50 may include a generally
rectangular opening 58 along the length of the separator 50. As
seen in FIGS. 1 and 5, tray 60 includes a generally rectangular
opening 62 that extends along the length of the tray 60 to a
distance adjacent the front 63 and rear 64 edges of the tray 60. A
projection 72 on the bottom of a pusher plate 70 snap-fits securely
into the opening 62 of the tray 60. As is well known in the art,
the pusher plate 70 and a coil spring (not shown), which fits into
a trough 74 of the pusher plate 70, serve as means of biasing
products toward the front 63 of the tray 60 as products are removed
from the tray 60. The coil spring abuts the pusher plate 70 and
biases the pusher plate 70 forwardly toward the front edge 63 of
tray 60.
[0072] As seen in FIGS. 8-10, base 40 may also include tracks 49A,
49B into which mounting brackets 90A, 90B can be fit. Mounting
brackets 90A, 90B are slid into tracks 49A, 49B to mount system 30
on a wire grid system 10 in the back of a case 20. As seen in FIG.
17A, grid system 10 includes a plurality of horizontal 12 and
vertical 14 bars. Each mounting bracket 90A, 90B includes one or
more hooks 92 located, when assembled, near the rear edge 45 of
base 40. Hooks 92 hook over horizontal bars 12 of the grid system
10 to mount the system 30 in place on the grid 10. Base 40 may
include additional tracks 49A, 49B to accommodate additional
mounting brackets 90A, 90B for mounting the system 30. Each
mounting bracket 90A, 90B could also include additional hooks 92
for hooking the mounting brackets 90A, 90B onto the grid system
10.
[0073] As seen in FIGS. 9-12, system 30 may also include adjustable
side arms 80 and 82 to accommodate different sized products. Arms
80, 82 are adjustable to contain various sizes of products so that
the products do not fall off the tray 60 over the side of the
system 30. Arms 80, 82 are movable in the directions indicated by
arrows E1, such that they can be positioned nearer the tray 60 and
away from the tray 60. As seen in FIG. 7, arms 80, 82 are coupled
to the tray 60 by flexible tabs 84A, 84B, 86A, 86B at the edges of
each arm 80, 82. Tabs 84A, 84B, 86A, 86B fit into slots 65 near the
front edge 63 of and rear edge 64 of tray 60. When arms 80, 82 are
in the first or unexpanded position, tabs 84A, 84B, 86A, 86B are
fit into the centermost slots 65 of the tray. To move the arms 80,
82 away from the tray 60 to the extended position (FIGS. 6, 12), a
user can pull outward on the arms 80, 82 until the tabs 84A, 84B,
86A, 86B loosen from the slots 65. When the arms 80, 82 are at the
desired position, tabs 84A, 84B, 86A, 86B fit into the appropriate
slots 65 to secure that arms 80, 82 at the desired expanded
position. Other means of moving and securing the arms 80, 82 may be
used. Alternatively, side rails may be used in place of arms 80,
82. Stationary side arms may also be used in lieu of movable arms
80, 82. Arms 80, 82 may also include vents 88 to allow the cool air
to easily travel to the front of the case 20. Also, as seen in an
alternate embodiment in FIGS. 9C and 9D, support arms 89 may be
coupled to base 40 to provide added stability to the arms 80, 82 in
their extended position.
[0074] System 30 also includes a front plate 100. Front plate 100
is aligned with the front edge 63 of tray 60 as seen in FIGS.
11-12. The front plate 100 acts as a product stop so that products
do not fall over the front edge 63 of the tray 60. Front plate 100
is coupled to the separator 50 by a lip 101 extending from front
plate 100 that fits into recesses 56 on bottom of separator 50 (see
FIGS. 3, 13). As shown best in FIG. 43B, snap-fit tabs 107b can be
used to fit the lip 101 into recesses 56. As seen in FIGS. 8 and
15, front plate 100 has a curved shape. This shape provides several
advantages over traditional flat front plates. First, when bagged
products are displayed on the system 30, the bottom curvature 102
gives a bigger footprint to the bottom of the bags to help in
keeping the bags upright on the tray 60. Additionally, the top
curvature 104 both helps to keep bagged products upright, and also,
with any shape of product used with the system 30, makes removal of
products easier as the products easily slide over the top curvature
104 for smooth removal from the tray 60 (as opposed to traditional
flat plates, which have a blunt straight top edge that can make
pulling products over the edge difficult). As seen best in FIG. 12,
front plate 100 also provides a display surface on which indicia
such as graphics, information, labels, tags or bar codes can be
placed. In the embodiment shown, front plate 100 includes a two
label holders 106, 108. First label holder 106 is sized to fit
standard-sized price tags. The second label holder 108 includes two
protrusions 108A, 108B to form the top and bottom walls of the
label holder 108. Because no side barriers are included, second
label holder 108 can accommodate non-traditional sized tags or
labels. Second label holder 108 could also be formed by including
differently-sized or shaped protrusions 108A, 108B and/or spacing
the protrusions 108A, 108B further apart or closer together to
accommodate various types and sizes of labels or tags. Front plate
100 further includes vents 109. As seen in FIGS. 11 and 17, vents
109 allow cool air which enters the at the rear of the system 30 to
flow through and out of the front of the system 30 through the
vents 109 (indicated by arrow A1).
[0075] FIGS. 42 and 42A show another embodiment of a front plate.
The front plate 100a includes an adapter plate 111a and coupler
plate 113a. The coupler plate 113a can be coupled to the separator
50 as described with respect to front plate 100. The adaptor plate
111a can be removably coupled to the coupler plate 113a via
channels 115a for quick and easy assembly, removal and replacement
of the adapter plate 111a. Like front plate 100, front plate 100a
can also include vents 109a and label holders 108a. Another
embodiment of a front plate is shown in FIGS. 43A and 43B. Like
front plate 100, the front plate 100b is curved and includes vents
109b and lip 101b. Front plate 100b includes a curved label holder
106b, and a short section 117b. FIG. 43B also shows snap-fit tabs
107b that can be used to fit any front plate of the present
invention to recesses 56 on the bottom of separator 50. Yet another
embodiment of a front plate is shown in FIGS. 44A and 44B. Like
front plate 100b, front plate 100c includes a curved label holder
106c, vents 109c and lip 101c.
[0076] System 30 can also include one or more plenum plates 110A,
110B. Each plenum plate 110 has a plurality of fingers 112. As seen
best in FIGS. 15A-15C, plenum plates 110A, 110B are attached to
base by channels 49A, 49B molded into the rear edge 45 of base 40.
Plenum plates 110A, 110B are also adjustable. To adjust plenum
plates 110A, 110B a user can slide the plates 110A, 11B toward
(15A) or away from (15B, 15C) the center of the base 40 in the
channels 49A, 49B. Plenum plates 110A, 110B can be adjusted to
align with the positioning of the adjustable arms 80, 82, and
adjustment also allows alignment of slits 114 between fingers 112
with the vertical grid wires 14. When mounting the system 30 onto a
grid 10, fingers 112 are placed between the vertical grid wires 14
and pushed through, so that vertical grid wires 14 slide through
slits 114 and into voids 116 in the plenum plates 110A, 110B and
system 30 is snap-fit onto the grid system 10. As seen in FIGS. 16
and 17, the fingers 112 act to capture cold air which would
otherwise drop behind the products (as shown by the lines C3) and
guide the cold air into the gap 44 in the system 30 (shown by the
arrow A1) to promote better cooling of the products displayed on
the system 30.
[0077] System 30 is also effective without plenum plates. FIGS.
40A, 40B and 41 show one embodiment of system 30 without plenum
plates. While the plenum plates are effective to direct cold air
into the gap 44, the placement of the fingers between the vertical
grid wires 14 can be an extra step in the installation process that
merchandisers may want to avoid. Without the plenum plates, cold
air still flows into gap 44 to sufficiently circulate cold air
beneath the products. For these reasons, merchandisers may prefer
the system 30 without plenum plates.
[0078] As shown in FIG. 17, cold air is pumped into the case 20 at
the front side of the case in the direction indicated by the arrow
C1. The cold air then circulates around the bottom of the case 20
and upward toward the top of the case 20 along the back wall of the
case 20, as indicated by the arrow C2. Normally, as shown by the
dotted line C3, the cold air then falls to the bottom of the case
20 behind the products, meaning cold air is not directed to the
products themselves. Not only does the insufficient direct cooling
present food safety issues, but the response to the issue is often
to increase the amount of cold air pumped into the case 20 to
decrease the overall air temperature in the entire case 20. The
increased energy necessary to cool the entire case 20 means an
increased expense to the retailer and possible damage to the food
from improper temperatures. To attempt to stop cold air from
falling behind the products, baffles are sometimes placed between
traditional display systems within the case to attempt to stop cold
air from falling behind the products and directing it to the
products on the shelves. However, as described above, the baffles
present a host of disadvantages to the retailer, consumer, and,
because of imprecise placement in the case, often fail to
sufficiently direct the cold air to the products on the
shelves.
[0079] The current system 30 solves these problems by allowing
proper cooling of the products through capturing of the falling
cold air (C3) and circulation under the products (A1) in one
easy-to-install, versatile, space-saving system 30. Ventilation of
the system 30 works as follows. As seen best in FIGS. 2, 2A and 17,
the assembled system 30 includes a gap 44 between the base member
40 and the separator 50, allowing cold air to pass through the gap
44 and beneath the products displayed on the system 30. If used,
the fingers 112 of the plenum plates 110A, 110B help capture the
falling cold air (C3) and direct it into the back of the system 30,
above the rear edge 45 of the base 40, and through the gap 44
beneath the products displayed on the system 30. The cold air then
exits the front of the system 30 through the vents 109 in the front
plate 100 aligned with the gap 44. This airflow through the system
is indicated by arrows A1. By allowing the cold air to flow beneath
the displayed products, the food is more directly cooled than in
traditional systems, without the use of baffles. The
self-ventilating system 30, by eliminating the need for baffles,
allows retailers to increase the number of systems 30 in a case by
placing them closer together and without space-wasting baffles in
between. Also, as seen in FIGS. 18 and 19, systems 30 do not have
to be linearly aligned across the case to accommodate baffles, and
as such a retailer has more freedom to vary the number and types of
systems 30 and products within a case 20.
[0080] In another embodiment shown in FIGS. 20-28, the system 30
includes a base member 400, separator portion 500 and tray 600. In
this embodiment, the separator portion 500 is stationary and does
not slidably connect to the base member 400. As seen in FIG. 21,
the tray 600 is snap-fit into the separator portion 500 by
inserting shafts 610 on the bottom of the tray 600 into holes 510
in the separator 500. The separator 500 is sized so that it
securely snap-fits into the base 400. As seen in FIGS. 23 and 24, a
gap 440 is provided between the base 400 and the separator 500
through which air can flow beneath products on the tray 600.
[0081] Similar to the embodiment including the pull-out features
shown in FIGS. 1-19, the embodiment in FIGS. 20-28 includes
adjustable side arms 800 and 820 to accommodate different sized
products by positioning them nearer the tray 600 and away from the
tray 600. As seen in FIG. 26, arms 800, 820 are coupled to the tray
600 by flexible tabs 840A, 840B, 806A, 860B at the edges of each
arm 800, 820. Tabs 840A, 840B, 860A, 806B fit into slots 650 near
the front and rear edges of tray 600. When arms 800, 820 are in the
first or unexpanded position, tabs 840A, 840B, 860A, 860B are fit
into the centermost slots 650 of the tray. To move the arms 800,
820 away from the tray 600 to the extended position, a user can
pull outward on the arms 800, 820 until the tabs 840A, 840B, 860A,
806B loosen from the slots 650. When the arms 800, 820 are at the
desired position, tabs 840A, 840B, 860A, 860B fit into the
appropriate slots 650 to secure that arms 800, 820 at the desired
expanded position. Stationary side arms may also be used in lieu of
movable arms 800, 820. Arms 800, 820 may also include vents 880 to
allow the cool air to easily travel to the front of the case
20.
[0082] As seen in FIGS. 20-22, 25 and 26, tray 600 includes a
generally rectangular opening 620 that extends along the length of
the tray 600. Similarly to the embodiment in FIGS. 1-19, a pusher
plate 700 snap-fits securely into the opening 620 of the tray 600.
The pusher plate 700 and a coil spring 710, which fits into a
trough 740 of the pusher plate 700, serve as means of biasing
products toward the front of the tray 600 as products are removed
from the tray 600. As seen in FIGS. 22-24 and 27-28, base 400 may
also include tracks 490A, 490B into which mounting brackets 900A,
900B can be fit. Mounting brackets 900A, 900B are slid into tracks
490A, 490B to mount system 30 on a wire grid system 10 in the back
of a case 20 as shown in FIG. 17A and described above.
[0083] Similar to the embodiment shown in FIGS. 1-19, the
embodiment of system 30 in FIGS. 20-28 also includes a front plate
1000. Front plate 1000 is coupled to the separator 500 by inserting
screws 1010 through holes 505 in the separator and tightening into
holes (not shown) in the front plate 1000. Front plate 1000 also
has the curved shape and display surface and advantages of these
features as described above with respect to the embodiment shown in
FIGS. 1-19. Front plate 1000 further includes vents 1090 to allow
cool air which enters the at the rear of the system 30 to flow
through and out of the front of the system 30 through the vents
1090 as described above.
[0084] In the embodiment shown in FIGS. 20-28, system 30 also can
include one or more plenum plates 1100A, 1100B. As seen in FIGS. 20
and 22-24, these plenum plates 1100A, 1100B are the same as those
described above with respect to previous embodiments, where each
plenum plate 1100 has a plurality of fingers 1120, and plenum
plates 1100A, 1100 are attached to base 400 by channels 495A, 459B
molded into the base 400. Plenum plates 1100A, 1100B are also
adjustable and can be adjusted to align with the positioning of the
adjustable arms 800, 820, and adjustment also allows alignment of
slits 1140 between fingers 1120 with the vertical grid wires 14,
where the grid wires 14 fit in the voids 1160 in the plates 1100A,
1100B. In the same way as described above and as seen in FIGS. 16
and 17, the fingers 1120 act to capture cold air which would
otherwise drop behind the products (as shown by the lines C3) and
guide the cold air into the gap 44 in the system 30 (shown by the
arrow A1) to promote better cooling of the products displayed on
the system 30. As with other embodiments, the system 30 is also
effective without the plenum plates.
[0085] The embodiment shown in FIGS. 20-28 fits into the same types
of cases 20 in the same way as described above and has the same
features and advantages as described above. It allows proper
cooling of the products through circulation of cold air under the
products (A1) in one easy-to-install, versatile, space-saving
system 30. If used, the fingers 1120 of the plenum plates 1100A,
1100B help capture the falling cold air (C3) and direct it into the
back of the system 30, above the rear of the base 400, and through
the gap 440 beneath the products displayed on the system 30. The
cold air then exits the front of the system 30 through the vents
1090 in the front plate 1000 aligned with the gap 440. By directing
the cold air to flow beneath the displayed products, the food is
more directly cooled than in traditional systems, without the use
of baffles.
[0086] In yet another embodiment of the system 30 shown in FIGS.
29-39, a baffle system 2000 is added to a standard merchandising
system 2500 to allow cold air to move under the products as
described above and shown in FIGS. 17-19. FIG. 29B shows one
example of a standard merchandising shelf 2500 to which a baffle
system 2000 may be added. The shelf may include a tray 2510, a
pusher plate 2520, a front plate 2530, a coil spring 2540, side
arms 2550A, 2550B which may be adjustable, and mounting brackets
2560A, 2560B. Other configurations of merchandising systems with
additional or modified components may also be used with a baffle
system 2000. By fitting a standard shelf 2500 with a baffle system
2000 as shown in FIG. 29A, cooling of the products on the shelf
2500 by directing cold air through the baffle system 200 beneath
the products may be accomplished without the need to purchase an
entirely new self-ventilating merchandising system. A baffle system
2000 as shown in FIGS. 30-39 would provide all of the advantages
described with respect to the other embodiments contemplated herein
(such as proper cooling of products, varied arrangements of shelves
in the cases, ventilation without the need for troublesome
stand-alone baffles placed between shelves, etc.), but could also
be easily coupled to standard merchandising shelves 2500 already in
use in refrigerator or freezer cases.
[0087] One embodiment of a baffle system 2000 in accordance with
the embodiment shown in FIGS. 29-39 that can be added to a standard
merchandising shelf 2500 is shown in FIGS. 30-32. Baffle system
2000 includes baffle base 2020, baffle wings 2030A, 2030B, wing
extensions 2040A, 2040B, and plenum plates 2050A, 2050B. Baffle
base 2020 snap-fits onto the merchandising shelf 2500, and as seen
in FIGS. 29A and 33-39, assembled baffle system 2000 works to
direct air from the back of the cooler beneath products on the
shelf 2500 to provide direct cooling to the products. Baffle base
2020 includes slots 2025 into which plenum plates 2050A, 2050B can
be slidably fit and allows slidable adjustment of the plenum plates
2050A, 2050B.
[0088] Baffle wings 2030A, 2030B snap-fit onto baffle base 2020. As
seen in FIGS. 30-32, openings 2032 in wings 2030A, 2030B are used
to movably attach wing extensions 2040A, 2040B to each wing 2030A,
2030B. Tabs 2042 on the wing extensions 2040A, 2040B friction fit
into the openings to allow wing extensions 2030A, 2030B to slide
toward and away from the center of the baffle base 2020. This
allows wing extensions 2030A, 2030B to be adjusted to accommodate
larger products which extend beyond the tray 2510 and are held in
place by extendable side arms 2550A, 2550B and ensure that cold air
directed by the plenum plates 2050A, 2050B (also adjustable to line
up with larger products extending beyond the tray 2510) is directed
beneath the entire product area. Thus, plenum plates 2050A, 2050B,
wing extensions 2030A, 2030B and arms 2550A, 2550B of the shelf
2500 can all be adjusted to accommodate products of varying sizes
to ensure that cold air is properly directed beneath the products.
Wing extensions 2030A, 2030B may also include vents 2045 to allow
further circulation of cold air beneath products on the tray 2510
above.
[0089] As seen best in FIG. 30, baffle base 2020 includes a gap
2010. Similar to the other embodiments shown and described herein,
the plenum plates 2050A, 2050B in this embodiment capture the
falling cold air (C3) and direct it into the back of the system 30,
through the gap 440 beneath the products displayed on the
merchandising shelf 2500. In the same way as described above and as
seen in FIGS. 16 and 17, the fingers 2054 of the plenum plates
2050A, 2050B act to capture cold air which would otherwise drop
behind the products (as shown by the lines C3) and guide the cold
air into the gap 2010 in the system 30 (shown by the arrow A1) to
promote better cooling of the products displayed on the system 30.
By directing the cold air to flow beneath the displayed products,
the food is more directly cooled than in traditional systems.
Plenum plates 2050A, 2050B, as seen in FIGS. 36-39, are adjustable,
and adjustment allows alignment of slits 2052 between fingers 2054
with the vertical grid wires 14, where the grid wires 14 fit in the
voids 2056 in the plates 2050A, 2050B. Thus, when plenum plates
2050A, 2050B are adjusted to accommodate products of varying sizes
on the shelf 2500, the slits 2052, fingers 2054, and voids 2056
ensure that the system 30 can be attached to a grid.
[0090] Although the invention has been herein described in what is
perceived to be the most practical and preferred embodiments, it is
to be understood that the invention is not intended to be limited
to the specific embodiments set forth above. Rather, it is
recognized that modifications may be made by one of skill in the
art of the invention without departing from the spirit or intent of
the invention and, therefore, the invention is to be taken as
including all reasonable equivalents to the subject matter of the
appended claims and the description of the invention herein.
