Description
CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application No. 60/355,835, filed Feb. 13, 2002, and U.S.
Provisional Application No. 60/418,178, filed Oct. 15, 2002.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a rack and, more
particularly, to a rack for carrying food products.
[0004] 2. Description of Related Art
[0005] Racks are often used in commercial kitchens to hold and
transport food products. For example, racks are used to hold hot
sheet pans after they have been removed from an oven. Racks also
can be used to carry items such as food boxes, insert pans, and
food trays.
[0006] Conventional racks typically have frames and supports that
are formed entirely of metal. Such racks have disadvantages due to
their all-metal construction. For example, a user's hands may stick
to the metal when the rack is used in cold applications. Also,
sharp edges on the metal parts may injure users or those around
them or can damage items contacted by the racks. In addition, the
racks are not aesthetically pleasing.
[0007] Conventional racks also can be unstable due to their design.
The racks are typically relatively tall and slender. This
configuration can cause them to tip during transport or if they are
subjected to a significant lateral force.
[0008] Carriers, such as sheet pans, that are supported by
conventional racks can slide out of position when being loaded or
transported. Conventional racks often have vertically displaced
supports, which are open at two opposing ends. Consequently, the
sheet pans are not fixed in place on the supports.
[0009] These racks also can occupy much valuable space. Often many
different racks are required because racks of different sizes are
needed to hold items of different sizes. Also multiple racks of the
same size are often required in a kitchen producing a high volume
of food products. When the racks are not being used, the floor
space they occupy can be significant. This is not only undesirable
in a commercial kitchen where space can be at a premium, but it can
be hazardous.
[0010] In addition, in a commercial kitchen producing a high volume
of food products, it can be difficult to move those products.
Conventional racks can be difficult to maneuver. Additionally, a
person typically can only move one rack at a time.
SUMMARY OF THE INVENTION
[0011] An aspect of the present invention relates to a rack for
transporting and storing carriers. The rack includes a base and
rolling members connected to the base. The rack also includes a
frame extending upwardly from the base. The frame includes a
plurality of supports for supporting carriers. The supports have
metal surfaces for contacting the carriers. The rack also includes
a bumper portion on at least a peripheral portion of the rack,
wherein the bumper portion is formed of plastic.
[0012] Another aspect of the present invention relates to a rack
for transporting and storing carriers. The rack has a frame
including a plurality of supports for supporting carriers. The
frame has corner regions within which the carriers can be
positioned. The rack also includes a base supporting the frame, the
base including projecting portions extending outward relative to
the corner regions of the frame. The rack further includes rolling
members connected to the projecting portions.
[0013] Yet another aspect of the present invention relates to a
rack for transporting and storing carriers. The rack includes a
base, rolling members connected to the base, and a frame extending
upwardly from the base. The frame includes a plurality of supports
for supporting carriers, and a first elongated restraining member
extending substantially vertically. The first elongated restraining
member is moveable substantially horizontally between a hold
position in which the first elongated restraining member inhibits
carriers from being removed from the frame and an unload position
in which the first elongated restraining member permits carriers to
be removed from the frame.
[0014] Yet another aspect of the present invention relates to a
rack for transporting and storing sheet pans. The rack includes a
first side panel including wire runners for supporting sheet pans,
a second side panel including wire runners for supporting sheet
pans, and a connector that connects the first side panel and the
second side panel. The connector is configured to be moveable from
an open position in which the first wire side panel is located a
maximum distance from the second wire side panel to a folded
position in which the first wire side panel is located a minimum
distance from the second wire side panel.
[0015] It is to be understood that both the foregoing general
description and the following detailed description are exemplary
and explanatory only and are not restrictive of the invention, as
claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0035] Reference will now be made in detail to the presently
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings. An effort has been made
to use the same reference numbers throughout the drawings to refer
to the same or like parts.
[0036] FIGS. 1-6 show a first preferred embodiment of a rack 10 for
transporting and storing carriers 90 according to the present
invention. The carriers 90 can be, for example, sheet pans, trays,
or boxes. The rack 10 includes a base 20, a top connector 30, a
frame 40, rolling members 50, and bumper portions 70.
[0037] The base 20 can provide support for the frame 40. The base
20 preferably is an integral member formed of plastic by, for
example, injection molding. A particularly preferred plastic is
polypropylene, although other plastics can be used, such as
high-density polyethylene. The base 20 can be configured to receive
a lower portion 41 of the frame 40. For example, the lower portion
41 of the frame 40 can be connected to the base 20 by conventional
techniques. For example, threads (not shown) can be provided on the
lower portion 41 and nuts (not shown) can be attached to the
threads after the lower portion 41 is inserted through the base 20.
The base 20 preferably includes an outer portion 22, which extends
around the periphery of the base 20 and forms a substantially
rectangular outer shape, and an inner portion 24, which is located
within the outer portion 22 and has a substantially X-shape that
provides structural stability while maintaining light weight.
[0038] The top connector 30 can assist in maintaining the frame 40
in an appropriate position. The top connector 30 is preferably an
integral member formed of plastic by, for example, injection
molding. A particularly preferred plastic is polypropylene,
although other plastics can be used, such as high-density
polyethylene. The top connector 30 can be configured to receive an
upper portion 42 of the frame 40. For example, the upper portion 42
of the frame 40 can be connected to the top connector 30 by
conventional techniques. For example, threads (not shown) can be
provided on the upper portion 42 and nuts (not shown) can be
attached to the threads after the upper portion 42 is inserted
through the top connector 30. As shown in FIG. 4, the top connector
30 preferably includes an outer portion 32, which extends around
the periphery of the top connector 30 and forms-a substantially
rectangular outer shape, and an inner portion 34, which is located
within the outer portion 32 and has a substantially X-shape that
provides structural stability while maintaining light weight.
[0039] The frame 40 is configured to support carriers 90, such as
sheet pan racks that are used in commercial kitchens. The frame 40
preferably includes a first side panel 43 and a second side panel
44. The first and second side panels 43, 44 extend between the base
20 and the top connector 30.
[0040] The first and second side panels 43, 44 preferably each
include outer vertically extending members 45 and inner vertically
extending members 46. The outer vertically extending members 45 can
form corner regions 47 of the frame 40. The inner vertically
extending members 46 provide a lateral boundary and thus assist in
retaining the carriers 90 on the frame 40. Preferably the carriers
90 can be fit within the corner regions 47 and are held laterally
in place in at least one direction by the inner vertically
extending members 46. Each of the inner and outer vertically
extending members 45, 46 preferably are formed of heavy metal rods,
which can have an outside diameter of 1/4 inch.
[0041] The first and second side panels 43, 44 also preferably each
include supports 48 that extend between the outer vertically
extending members 45. The supports 48 can be connected to the outer
vertically extending members 45 by conventional means, such as
welding. The supports 48 preferably are configured to support
carriers 90. The supports 48 each have a contact surface 49 that
contacts the carriers 90. See FIG. 2. The contact surface 49 of the
supports 48 is preferably formed of metal, to provide resistance to
deformation or damage caused by the high heat of the carrier 90.
Also, metal is resistant to abrasion caused by sliding carriers 90
over the supports 48. As shown in the preferred embodiment, the
entire support 48 is formed of metal. The supports 48 can be, for
example, formed of heavy metal rods, which can have an outside
diameter of 1/4 inch.
[0042] The rolling members 50 can be provided on the rack 10 to
provide mobility. The rolling members 50 may be, for example,
casters that are connected to the base 20 in a conventional manner.
Other conventional rolling members could be used. Preferably the
rolling members 50 are free to pivot such that they can move in any
direction.
[0043] One or more handles 60 can also be provided on the rack.
This first preferred embodiment includes two handles 60. Each
handle 60 has a grip or cross member 61 extending between first and
second connecting portions 62. The grip member 61 can be fit into
recesses in the connecting portions 61, 62 and held in place by
bolts (not shown). The connecting portions 62 are preferably
connected to the frame 40 by conventional screws that extend into a
member (not shown) on an opposite side of the frame. The grip
member 61 is preferably formed of metal and the first and second
connecting portions 62 are preferably formed of plastic. A
particularly preferred plastic is polypropylene, although other
plastics can be used, such as high-density polyethylene.
[0044] The bumper portion 70 is provided on the rack 10 to reduce
negative effects that may result from the bumping the rack 10 into
something or someone. The bumper portion 70 is preferably made of
plastic, due to its ability to absorb impact. A particularly
preferred plastic is polypropylene, although other plastics can be
used, such as high-density polyethylene. The bumper portion 70 can
be provided in one location or in a variety of locations on the
rack. In this first preferred embodiment, bumper portions 70 are
provided on the base 20, on the top connector 30, and on the frame
40. The bumper portion 70a is formed as part of the base 20 and
extends around the periphery of the base 20. The bumper portion 70b
is formed as part of the top connector 30 and extends around the
periphery of the top connector 30. The bumper portions 70c are
formed as part of the handles 60 and are provided on the four
corners of the frame 40. Instead of being integral parts of the
base 20, top connector 30, and handles 60, the bumper portions 70
can be members attached to those structures.
[0045] A first elongated restraining member 80 can also be provided
on the rack to provide a lateral boundary and assist in retaining
the carriers 90 on the frame 40. The first elongated restraining
member 80 extends substantially vertically. It is moveable
substantially horizontally in the direction of arrow A between a
hold position in which the first elongated restraining member 80
inhibits carriers 90 from being removed from the frame 40 and an
unload position in which the first elongated restraining member 80
permits carriers 90 to be removed from the frame 40. The elongated
restraining member 80 can be, for example, a heavy metal rod, which
can have an outside diameter of 3/8 inch. The restraining member 80
is preferably pivotally connected to the base 20 and the top
connector 30, although it could be connected directly to the frame
40.
[0046] As shown in FIGS. 5 and 6, the restraining member 80
includes an upper substantially U-shaped segment 81 and a lower
substantially S-shaped segment 82. Portions of the segments 81 and
82 are pivotally disposed in corresponding holes 26 and 36 in the
base 20 and top connector 30, respectively. The pivotal connections
allow the restraining member 80 to move between the hold and unload
positions. Two depressions 37 and 38 in the top connector 30 serve
as holders that can maintain the elongated restraining member 80 in
the hold and unload positions, respectively. The elongated
restraining member 80 is automatically maintained in the hold and
unload positions by the depressions 37 and 38. That is, once the
elongated restraining member 80 is moved into on of the depressions
37 or 38, no further effort is required to maintain the elongated
restraining member 80 in that position. However, the elongated
restraining member 80 is maintained in that position in a manner
that permits the first elongated restraining member to later be
removed. The upper segment 81 fits into the depression 37 or 38 and
is held in place by the force of a spring 83, which is fixed onto
the end of segment 81 by washers 84 and 85 and nut 86. The force of
the spring 83 can be overcome to move the restraining member 80
between the depressions 37, 38. A second elongated restraining
member 80 can be positioned on a side of the frame 40 opposite to
the first elongated restraining member.
[0047] FIGS. 7 to 10 show a second preferred embodiment of a rack
110 for transporting and storing carriers 90 according to the
present invention. The rack 110 of this second embodiment is
similar to the rack 10 of the first embodiment in many respects. In
this embodiment, however, the rack 110 has a base 120 with four
projecting portions 128 extending and projecting outward relative
to the corner regions 47 of the frame 40. The projecting portions
128 are preferably outriggers that extend outward from a primary
portion 129 of the base 120, as shown in the drawings. The base
could be configured such that the projecting portions project
outward relative to the corner regions 47 of the frame 40, but do
not project outward from the primary portion of the base. That is,
the primary portion of the base would fully envelope the projecting
portions.
[0048] In this embodiment, the rolling members 50 are connected to
the projecting portions. The rolling members 50 are preferably
positioned on outermost areas of the projecting portions. The
rolling members 50 can be positioned on the projecting portions at
a distance that is at least about 1.3 times a width of the frame
40.
[0049] By providing the rolling members 50 on projecting portions
128 extending outward relative to the frame 40, the stability of
the 110 rack is greatly enhanced. A test was conducted to determine
the difference in stability between racks constructed according to
the first and second embodiments. Both racks had frames of the same
size, but had bases of different sizes. The rack according to the
first embodiment had a caster footprint (swivel center to swivel
center) of 20.286 inches wide by 25.506 inches long. The rack
according to the second embodiment had a caster footprint (swivel
center to swivel center) of 27.51 inches wide by 33.48 inches long.
The test results are reproduced below:
1 Front Side Tip (lbf) Tip (lbf) Front Tip (lbf) Side Tip (lbf) No
Load No Load 175 lbs. Load 175 lbs. Load Emb. 1 15.0 10.5 42.5 31.5
Emb. 2 19.5 14.5 66.5 52.0 Stability Incr. 30% 38% 56.5% 65%
[0050] As shown by this test, the rack according to the second
embodiment has greatly improved stability. The stability increase
is particularly noticeable when the rack contains carriers that add
a load of 175 lbs.
[0051] FIGS. 11 to 14 show a third preferred embodiment of a rack
210 according to the present invention. The rack 210 of this third
embodiment is similar in some respects to the rack of the first
embodiment. This third embodiment, however, has different
structures for the base 220, top connector 230, and frame 240.
[0052] The frame 240 has first and second side panels 243, 244 that
preferably each include vertically extending members 245 and
supports 248 extending between the vertically extending members
245. The supports 248 preferably are configured to support carriers
90. The side panels 243, 244 are preferably made from metal, such
as aluminum or stainless steel, but they could be made from
plastic. If the side panels 243, 244 are made from metal they
preferably are formed by stamping or welding. If the side panels
are made from plastic, they preferably are formed by injection
molding.
[0053] The base 220 and the top connector 230 position the side
panels 243, 244 relative to one another. The base 220 and the top
connector are preferably made from plastic by injection molding.
They could, however, be made from another material such as
metal.
[0054] The base 220 includes a first fixed bottom member 221
connected to the first side panel 243 by a conventional connection
and connected to a first movable bottom member 223 by a movable
connection, such as a hinge 222. The base 220 also includes a
second fixed bottom member 224 connected to the second side panel
244 by a conventional connection and connected to a second movable
bottom member 226 by a movable connection, such as a hinge 225. As
shown in FIG. 3, the first and second movable bottom members 223,
226 are preferably connected by a movable connection, such as a
hinge 227.
[0055] Similarly, the top connector 230 includes a first fixed top
member 231 connected to the first side panel 243 by a conventional
connection and connected to a first movable top member 233 by a
movable connection, such as a hinge 232. The top connector 230 also
includes a second fixed top member 234 connected to the second side
panel 244 by a conventional connection and connected to a second
movable top member 236 by a movable connection, such as a hinge
235. As shown in FIG. 2, the first and second movable top members
233, 236 are preferably connected by a movable connection, such as
a hinge 237.
[0056] The base 220 and top connector 230 can be folded to conserve
space when the rack 210 is not in use. As shown in FIG. 14, the
base 220 and top connector 230 are folded at hinges 222, 227, 225,
232, 237, 235 to bring the side panels 243, 244 closer together and
reduce the space occupied by the rack 210. The rack 210 can be held
in the folded position by a pivoting latch 95 having an arm 96
pivotally mounted on the second movable top member 236 so as to
engage a post 97 on the first movable top member 233.
[0057] FIGS. 15 to 18 show a fourth preferred embodiment of a rack
310 according to the present invention. The rack 310 of this fourth
embodiment is similar in many respects to the rack of the third
embodiment. This fourth embodiment, however, has different
structures for the base 320 and top connector 330.
[0058] The base 320 and top connector 330 preferably can hold the
side panels 243, 244 in many positions relative to one another. The
base 320 and top connector 330 are preferably made from plastic by
injection molding. They could, however, be made from another
material, such as metal.
[0059] The base 320 includes a first fixed bottom member 321
connected to the first side panel 243 by a conventional connection
and connected to a movable bottom member 323 by a movable
connection, such as a hinge 322. The base 320 also includes a
second fixed bottom member 324 connected to the second side panel
244 by a conventional connection and connected to the movable
bottom member 323 by a movable connection, such as a hinge 325.
[0060] Similarly, the top connector 330 includes a first fixed top
member 331 connected to the first side panel 243 by a conventional
connection and connected to a movable top member 333 by a movable
connection, such as a hinge 332. The top connector 330 also
includes a second fixed top member 334 connected to the second side
panel 244 by a conventional connection and connected to the movable
top member 333 by a movable connection, such as a hinge 335.
[0061] The hinges 322, 325, 332, 335 preferably can be locked in a
variety of positions. One hinge (i.e., 332) is shown in FIG. 16 for
purposes of illustration. Preferably, the remaining hinges have the
same structure as the illustrated hinge. Contacting sections of the
fixed member 331 and movable member 333 preferably have holes 382
extending through them. A pin 380 can be inserted in the holes 382
of the fixed member 331 and movable member 333 to fix those members
relative to one another. By providing a variety of holes 382, the
angular relationship between the fixed member 331 and movable
member 333 can be changed, thus changing the spacing between the
first and second side panels 243, 244. Accordingly the width of the
rack 310 can be adjusted to accommodate different width
trays/containers, such as food boxes, sheet pans, insert pans, and
meat trays. This adjustability creates a more flexible rack for
multiple uses.
[0062] The base 320 and top connector 330 also can be folded to
conserve space when the rack 310 is not in use. As shown in FIG.
17, the base 320 and top connector 330 are folded along hinges 322,
325, 332, 335 to bring the side panels 243, 244 closer together and
reduce the space occupied by the rack 310. The rack 310 can be held
in the folded position by inserting the pin 380 in an appropriate
one of the holes 382 in hinge 332.
[0063] Additionally, multiple racks 310 can be nested. As shown in
FIG. 18, one rack 310 can be inserted into another rack 310 to nest
the racks 310. Nesting of the racks 310 reduces the space needed to
store the racks 310 when they are not in use.
[0064] Other embodiments of the invention will be apparent to those
skilled in the art from consideration of the specification and
practice of the invention disclosed herein. It is intended that the
specification and examples be considered as exemplary only, with a
true scope and spirit of the invention being indicated by the
following claims.
