Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 11/092,453 filed Mar. 29, 2005.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates generally to a household dishwasher
with a utensil rack and a slide for supporting the utensil
rack.
[0004] 2. Description of the Related Art
[0005] Automatic dishwashers are well known, especially those for
use in household environments. A typical automatic dishwasher
comprises a cabinet that defines a washing chamber, which is
accessible through a moveable door. Typically, an upper rack and a
lower rack for holding utensils to be cleaned are provided within
the washing chamber. Both the upper and lower racks are slidably
mounted within the washing chamber in such a manner that at least a
major portion of the racks can be slid substantially beyond the
washing chamber to ease the loading of the racks.
[0006] A problem associated with conventional dishwasher racks
relates to the slides that mount the racks to the side walls of the
dishwasher cabinet. Usually, the racks include wheels or similar
devices mounted to the sides thereof, and the wheels ride within a
slide movably mounted to the cabinet. To remove the rack from the
dishwasher, the user pulls the rack out of the wash chamber by
sliding the wheel toward the end of the slide and, once the rack
reaches the end of the slide, removes the wheels from the slide,
usually by slightly lifting the rack to lift the wheel over a
detent in the slide while continuing to pull. However, with such a
configuration, it is easy for the user to accidentally pull the
wheel over the detent while pulling the rack out of the wash
chamber in a normal fashion and thereby unintentionally remove the
rack from the slide. It is therefore desirable to have an automatic
dishwasher with a slide that prevents undesired removal of the
rack.
SUMMARY OF THE INVENTION
[0007] An automatic dishwasher according to another embodiment of
the invention comprises an open-faced cabinet comprising opposing
side walls and defining a wash chamber; a door movably mounted to
the cabinet for selectively closing the wash chamber; a utensil
rack comprising opposing sides; at least one track defining an
elongated raceway and comprising a stop terminating at a forward
end of the raceway and an access opening to the raceway; and a
wheel assembly comprising at least one wheel slidably received
within the raceway and sized for insertion and removal through the
access opening. One of the track and wheel assembly is mounted to
one of the cabinet and utensil rack and the other of the track and
wheel assembly is mounted to the other of the cabinet and utensil
rack to slidably mount the utensil rack to the cabinet, and the
wheel moves along the raceway to the access opening for removal
through the access opening. A closure can be provided for closing
the access opening.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0030] Referring now to the figures, FIG. 1 shows a household
dishwasher 10 according to one embodiment of the invention
comprising a cabinet 12 having spaced upper and lower walls 14, 16
joined by opposing side walls 18, 20 and a rear wall 22 to form an
open-faced wash chamber 24. A door 26 movably mounted to the
cabinet 12 is movable between an open position, as shown in FIG. 1,
wherein the user can access the wash chamber 24, and a closed
position, wherein the door 26 closes the open face of the wash
chamber 24 in a conventional fashion. The dishwasher 10 further
comprises a lower, first utensil rack 28 and a higher, second
utensil rack 30 slidably mounted the side walls 18, 20 of the
cabinet 12. The first and second utensil racks 28, 30 are
preferably conventional utensil racks commonly utilized in present
day household dishwashers for holding various utensils, such as
plates, bowls, other tableware, and beverage containers. Usually,
the first utensil rack 28 is adapted to hold plates, bowls, and
large items, such as pots and pans, and the second utensil rack 30
is spaced a sufficient distance above the first utensil rack 28 to
accommodate the items in the first utensil rack 30. The second
utensil rack 30 commonly holds beverage containers, such as glasses
and cups, and other small items. However, the first and second
utensil racks 28, 30 can be arranged in the dishwasher 10 in any
suitable fashion and can hold any utensils that can be washed in
the dishwasher 10. During operation of a wash cycle of the
dishwasher 10, the door 26 is in the closed position, and the first
and second utensil racks 28, 30 are disposed within the wash
chamber 24 and exposed to washing fluid, such as water, and wash
aids, such as detergents and rinse aids. When dishwasher 10 is not
operating, the user can move the door 26 to the open position and
slide the first and second utensil racks 28, 30 from the wash
chamber to empty or fill the first and the second utensil racks 28,
30.
[0031] As shown in FIG. 2, according to one embodiment of the
invention, the dishwasher 10 can further comprise a third utensil
rack 40 slidably mounted to the cabinet 12 by a pair of slides 42.
The third utensil rack 40 can be positioned above the second
utensil rack 30 and near the upper wall 14 within the wash chamber
24 and can move relative to the wash chamber 24 in the same manner
as described above for the first and second utensil racks 28, 30.
The third utensil rack 40 comprises a frame 44 that supports a pair
of removable basket elements 46A, 46B, which can hold several types
of utensils having various sizes and shapes.
[0032] Referring now to FIG. 3, the frame 44 comprises an upper
U-shaped wire 48 and a generally rectangular lower peripheral wire
50 joined by a plurality of spaced and generally vertical
connecting wires 52. The peripheral wires 48, 50 form spaced front
and rear ends 54, 56 connected by opposing sides 58, 60. The
U-shaped wire 48 is oriented such that it opens at the rear end 56,
and the lower peripheral wire 50 is formed by a pair of opposed,
U-shaped front and rear lower peripheral wires 50A, 50B that join
at the opposing sides 58, 60. The frame 44 further comprises a
front upper support rail 62 and a rear upper support rail 63 that
extend between and above the opposing sides 58, 60 of the upper
peripheral wire 48 and are parallel to and spaced from the front
end 54 and the rear end 56, respectively. Additionally, the frame
44 includes a first pair of opposing lower support rails 64 and a
second pair of opposing lower support rails 66 on the opposing
sides 58, 60 of the frame 44. The first pair of lower support rails
64 is integral with the front upper support rail 62, and,
similarly, the second pair of lower support rails 66 is integral
with the rear upper support rail 63. Each of the lower support
rails 64, 66 is elongated and generally U-shaped and depends from
the upper peripheral wire 48 such that it extends below the lower
peripheral wire 50. Thus, the upper support rails 62, 63 are
vertically spaced from the lower support rails 64, 66. The upper
and lower peripheral wires 48, 50, the upper support rails 62, 63,
and the lower support rails 64, 66 are preferably metal wires
coated with polymeric materials that can withstand the environment
of the wash chamber 24 and protect the metal wires from corrosion.
Alternatively, the upper and lower peripheral wires 48, 50, the
upper support rails 62, 63, and the lower support rails 64, 66 can
be composed entirely of polymeric materials.
[0033] Referring now to FIG. 4, according to one embodiment of the
invention, the basket elements 46A, 46B, which rest on the frame
44, each comprise an upstanding peripheral wall 70 and a grid
formed by a plurality of intersecting ribs 72 that form a bottom
wall surrounded by the peripheral wall 70. The intersecting ribs 72
are spaced from one another a distance suitable for holding
utensils such as silverware, spatulas, and the like. Further, the
bottom wall optionally includes at least one small item support
area 68 comprising intersecting support ribs 86 that are spaced
closer than the intersecting ribs 72 to support small items, such
as corn cob holders, that can potentially fall between the
intersecting ribs 72. As shown in FIG. 4, the small item support
areas 68 are preferably located in corners of basket elements 46A,
46B, but they can be located in any suitable region of the bottom
wall.
[0034] The peripheral wall 70 comprises parallel and spaced first
and second edges 70A, 70B joined by spaced third and fourth edges
70C, 70D. Each of the first and second edges 70A, 70B are
substantially straight and can include a carry handle 80 formed
integrally therewith. Each of the handles can comprise a lateral
hook or flange 82 sized to receive the upper and lower support
rails 62, 63, 64, 66. The third edge 70C is generally straight and
perpendicular to the first and second edges 70A, 70B, while the
fourth edge 70D can comprise an intermediate curve 74 to form a
first basket element portion 76 and a second basket element portion
78 that is wider than the first basket element portion 76. As a
result of this configuration, utensils of different length can be
efficiently arranged within the basket elements 46A, 46B. As shown
in FIG. 4, relatively short utensils A, such as standard forks and
spoons, can be placed in the first basket element portion 76 in an
orientation parallel to the first and second edges 70A, 70B, while
medium length utensils B, such as table knives, can fit in the
second basket element portion 78 also in an orientation generally
parallel to the first and second edges 70A, 70B. Additionally, the
basket elements 46A, 46B are sized so that relatively long utensils
C, such as spatulas, mixing spoons, chef knives, and the like, can
be arranged across both the first and second basket element
portions 76, 78 in an orientation parallel to the third edge 70C
and generally perpendicular to the relatively short utensils A and
the medium length utensils B. As illustrated in FIG. 4, the
relatively long utensils C are longer than the medium length
utensils B, which are longer than the relatively short utensils A.
However, the utensils can be placed in any suitable location of the
basket elements 46A, 46B. For example, the relatively short
utensils A can be placed in the second basket element portion 78,
if desired.
[0035] Each basket element 46A, 46B can further comprise a
plurality of tines 88 projecting upward from the intersecting ribs
72 to support and separate individual utensils. The tines 88 can be
arranged in groups so that the user can efficiently position
utensils of different length in different areas of the basket
elements 46A, 46B. A first tine group 90 extends along the fourth
edge 70D for holding utensils in an orientation parallel to the
first and second edges 70A, 70B, and a second tine group 92 is
disposed along the second edge 70B for holding utensils in an
orientation parallel to the third edge 70C. Preferably, the tines
88 in the first tine group 90 are spaced to hold relatively thin
utensils, such as table knives, spoons, and forks (i.e., the
relatively short utensils A and the medium length utensils B),
while the tines 88 in the second tine group 92 are spaced farther
apart to accommodate wider utensils, such as spatulas (i.e., the
relatively long utensils C). Further, the tines 88 are preferably
arranged in pairs of tines to form two parallel rows 88A, 88B of
tines 88. As a result of this configuration, the utensils
positioned between the tines 88 are held by the tines 88 at two
locations along the length thereof, and, therefore, the rows 88A,
88B of tines 88 prevent pivotal movement of the utensils and
maintain the utensils in the orientation generally parallel to the
first and second edges 70A, 70B or parallel to the third edge 70C.
Additionally, the second group of tines 92 includes a third row 88C
of tines 88 along the first edge 70A for securing both ends of the
relatively long utensils C to prevent the pivotal movement
thereof.
[0036] Referring back to FIG. 2, according to one embodiment of the
invention, the fourth edges 70D of the basket elements 46A, 46B are
complementary and matingly abut one another when the basket
elements 46A, 46B are seated on the frame 44. As a result, the
first edges 70A, the second edges 70B, and the third edges 70C of
both of the basket elements 46A, 46B form a generally rectangular
periphery with a minor discontinuation at the interface between the
basket elements 46A, 46B. Further, because the basket elements 46A,
46B are complementary, the basket elements 46A, 46B mate to form a
whole, generally rectangular basket. The whole basket is defined by
the rectangular periphery and has a surface area slightly less than
the area defined between the front and rear ends 54, 56 and the
opposing sides 58, 60 of the frame 44. In particular, the whole
basket corresponds to a single basket sized to span in one
direction between the upper support rails 62, 63 and in the other
direction a distance slightly less than the distance between the
first and second pairs of opposing lower support rails 64, 66. In
the illustrated embodiment, the first basket element portion 76 of
the first basket element 46A aligns with the second basket element
portion 78 of the second basket element 46B, and the second basket
element portion 78 of the first basket element 46A aligns with the
first basket element portion 76 of the second basket element 46B to
form the whole basket, which has a constant width equal to the sum
of the individual widths of the basket element portions 76, 78.
Preferably, the basket elements 46A, 46B are identical in shape and
size so that each of the basket elements 46A, 46B accounts for
about one half of the whole basket. Further, production costs are
minimized when the basket elements 46A, 46B are identical because
only a single mold design is required for all of the basket
elements 46A, 46B.
[0037] The basket elements 46A, 46B are adjustably mounted to the
frame 44 to accommodate utensils held by the second utensil rack 30
and utensils held by the basket elements 46A, 46B and to
efficiently utilize the limited space in the wash chamber 24. In
particular, the basket elements 46A, 46B can be vertically
adjustable on the frame 44 and, therefore, within the wash chamber
24. As shown in FIGS. 2 and 5, according to one embodiment of the
invention, the basket elements 46A, 46B can be mounted in an upper
position wherein the flanges 82 on the first and second edges 70A,
70B rest on the upper support rails 62, 63. As shown in FIGS. 6 and
7, according to one embodiment of the invention, the basket
elements 46A, 46B can be mounted in a lower position, wherein the
flanges 82 on the first and second edges 70A, 70B rest on the first
and second pairs of opposing lower support rails 64, 66. A
comparison of FIGS. 5 and 7 shows that the basket elements 46A, 46B
are located higher in the wash chamber 24 when in the upper
position. Further, the bottom walls formed by the intersecting ribs
72 of the basket elements 46A, 46B are spaced from the second
utensil rack 30 a greater distance when the basket elements 46A,
46B are in the upper position than when the basket elements 46A,
46B are in the lower position, but clearance between the bottom
walls and the upper wall 14 of the cabinet 12 is greater when the
basket elements 46A, 46B are in the lower position than when in the
upper position. Mounting the basket elements 46A, 46B in the upper
and the lower positions is, therefore, a compromise between spacing
between the second utensil rack 30 and the third utensil rack 40
and clearance between the third utensil rack 40 and the upper wall
14 of the cabinet 12. Additionally, the basket elements 46A, 46B in
the upper position are oriented generally orthogonal to the basket
elements 46A, 46B in the lower position because the portions of the
frame 44 that support the basket elements 46A, 46B in these two
positions are oriented orthogonal to one another. Such an
arrangement facilitates mounting the basket elements 46A, 46B to
the frame 44 since the upper support rails 62, 63 do not interfere
with the basket elements 46A, 46B when mounting them on the first
and second pairs of opposing lower support rails 64, 66 and
vice-versa.
[0038] Referring particularly to FIG. 8 and generally to FIG. 3,
the slides 42 that slidably mount the third utensil rack 40 to the
cabinet 12 each comprise a track 100 having a generally vertical
middle wall 102 with an aperture 103 near a front end thereof and
pairs of upper and lower L-shaped flanges 104, 106 extending along
the middle wall 102 to define an inner raceway 110 on an interior
side (i.e., the side closer to the third utensil rack 40) of the
middle wall 102 and an outer raceway 110 on an outer side (i.e.,
the side farther from the third utensil rack 40) of the middle wall
102. The raceways 110, 112 terminate at a pair of stops in the form
of front flanges 108 at the front end of the track 100. The upper
flange 104 that partially defines the inner raceway 110 is spaced
from the front flange 108 on the interior side of the middle wall
102 to form an access opening 114 therebetween. A closure 120
pivotally mounted to the upper and lower flanges 104, 106 of the
track 100 selectively blocks the access opening 114. The closure
120 comprises parallel upper and lower walls 122, 124 joined by a
side wall 126 and a front wall 128 orthogonal to the side wall 126.
The side wall 126 and the front wall 128 form a grip 130 sized to
be grasped between a user's fingers for pivotally moving the
closure 120. Additionally, the closure 120 includes a detent 132
that extends from the side wall 126 and is sized to mate with the
aperture 103. The closure 120 is movable between a closed position,
as shown in FIG. 9A, wherein the upper wall 122 blocks the access
opening 114, and an opened position, as illustrated in FIG. 9B,
wherein the closure 120 is pivoted away from the track 100 so that
the upper wall 122 is spaced from the access opening 114.
[0039] Referring particularly to FIG. 10 and generally to FIG. 3, a
wheel support 140 couples each opposing side 58, 60 of the third
utensil rack 40 to its corresponding slide 42. Each wheel support
140 is an elongated, generally rectangular member with front and
rear wheels 142, 144 rotatably mounted to an outer side thereof.
The wheels 142, 144 are sized for receipt within the access opening
114 and the inner raceway 110. The wheel support 140 further
includes a pair of parallel grooves 146 on an interior side thereof
for receiving the upper and lower peripheral wires 48, 50 of the
frame 44. Snap clamps 150 adjacent the grooves 146 are sized to
securely receive at least one of the upper and lower peripheral
wires 48, 50 to prevent lateral translation of the wheel support
140 relative to the frame 44. Additionally, the interior side of
the wheel support 140 includes sets of vertically aligned U-shaped
projections 148 between the grooves 146 sized to receive brackets
152 for sandwiching the frame 44 between the wheel support 140 and
the brackets 152 to thereby mount the wheel support 140 to the
frame 44. The wheel support 140 also comprises an upwardly and
outwardly extending overhang 154 to facilitate mounting the wheel
support 140 to the track 100.
[0040] An exemplary description of the assembly and operation of
the third utensil rack 40 and the slides 42 follows. It will be
apparent to one of ordinary skill that the assembly and operation
can proceed in any logical order and is not limited to the sequence
presented below. The following description is for illustrative
purposes only and is not intended to limit the invention in any
way.
[0041] Each of the slides 42 is mounted to the dishwasher 10 by
attaching the track 100 to a conventional slide mount (not shown)
on the corresponding opposing side wall 18, 20. The slide mount can
be any suitable type of device that couples the track 100 to the
corresponding opposing side wall 18, 20. For example, the slide
mount can comprise one or more wheels mounted to the side walls 18,
20. Typically, the track 100 receives the slide mount within the
outer raceway 112 so that the track 100 can slide relative to the
cabinet 12. Next, the wheel supports 140 are mounted to the
opposing sides 58, 60 of the frame 44 by aligning the upper and
lower peripheral wires 48, 50 with the grooves 146, snapping the
lower peripheral wire 50 into the snap clamps 150, and inserting
the brackets 152 into the projections 148 to clamp the upper and
lower peripheral wires 48, 50 between the wheel support 140 and the
brackets 150. After the wheel supports 140 are secured to the frame
44, the user pivots the closures 120 on the slides 42 to the opened
position so that the rear wheels 144 can be inserted into the inner
raceways 110 through the access openings 114. The user then pushes
the frame 44 towards the wash chamber 24 so that the rear wheels
144 travel along the inner raceway 110 until the front wheels 142
are aligned with the access openings 114, as shown in FIG. 11.
After the user inserts the front wheels 142 into the inner raceway
110 through the access openings 114, the user pivots the closures
120 toward the track 100 to the closed position, wherein the
detents 132 mate with the apertures 103, and the upper walls 122
block the access openings 114 to prevent inadvertent removal of the
front wheels 142 from the inner raceways 110, as shown in FIG. 9A.
In this position, the overhangs 154 of the wheel supports 140 rest
on the upper flanges 104 of the track 100 to help support the frame
44 on the slides 42. When the slides 42 are mounted to the cabinet
12 and the frame 44 is mounted to the slides 42, the third utensil
rack 40 is thereby mounted to the dishwasher 10 and can slide
relative to the wash chamber 24.
[0042] The user can mount the basket elements 46A, 46B to the frame
44 in either the upper position or the lower position depending on
the desired configuration of the utensil racks 28, 30, 40 in the
wash chamber 24, the sizes of the utensils in the second utensil
rack 30, and the sizes of the utensils to be held in the third
utensil rack 40. To maximize the space between the second utensil
rack 30 and the basket elements 46A, 46B, the basket elements 46A,
46B are placed adjacent one another in the upper position, as shown
in FIGS. 2 and 5, with the flanges 82 on the upper support rails
62, 63. Further, the basket elements 46A, 46B are positioned with
their complementary, fourth edges 70D in abutting contact to form
the whole basket. However, if the user desires to maximize the
clearance between the basket elements 46A, 46B and the upper wall
14 of the cabinet 12 to fit larger utensils in the third utensil
rack 40, the basket elements 46A, 46B are rotated 90-degrees and
placed adjacent one another in the lower position, as illustrated
in FIGS. 6 and 7, with the flanges 82 on the first and second
opposing pairs of lower support rails 64, 66. As in the upper
position, the basket elements 46A, 46B are positioned with their
complementary, fourth edges 70D in abutting contact to form the
whole basket.
[0043] With the basket elements 46A, 46B in either the upper
position or the lower position, the user can fill the basket
elements 46A, 46B with various shapes and sizes of utensils,
including the relatively short utensils A, the medium length
utensils B, and the relatively long utensils C, as described above.
The utensils can be arranged in the basket elements 46A, 46B in any
suitable fashion to maximize the quantity of utensils held by the
third utensil rack 40 without compromising the ability of the
dishwasher 10 to clean the utensils. Additionally, the user can
place small items, such as corn cob holders, in the small item
support areas 68. During operation of a wash cycle, the tines 88
surrounding the small item support areas 68 help retain the small
items in the small item support areas 68.
[0044] After the wash cycle is complete, the user pulls the third
utensil rack 40 from the wash chamber to empty the basket elements
46A, 46B. The front stop flanges 108 limit the forward movement of
the frame 44 relative to the slides 42. Next, the user removes the
utensils from the third utensil rack 40 in any suitable manner. For
example, the user can either manually remove each utensil from the
basket elements 46A, 46B while the basket elements 46A, 46B are
mounted to the frame 44, the user can remove at least one of the
basket elements 46A, 46B with the utensils therein and empty the at
least one basket element 46A, 46B at a location separate from the
dishwasher 10, or the user can remove at least one of the basket
elements 46A, 46B with the utensils therein and use the at least
one basket element 46A, 46B for utensil storage, such as by placing
the at least one basket element 46A, 46B in a drawer.
[0045] If the user desires to remove the entire frame 44 from the
dishwasher, the user pivots the closures 120 away from the tracks
100 to the opened position, as shown in FIG. 9B, to unblock the
access openings 114. The closures 120 in the illustrated embodiment
advantageously remain mounted to the tracks 100 during movement
between the closed and opened positions and while in the opened
position. Next, the user aligns the front wheels 142 with the
access openings 114 and lifts the frame 44, such as by pivoting the
frame 44, to thereby lift the front wheels 142 through the access
openings 114, as illustrated in FIG. 11. Thereafter, the user pulls
the frame 44 further from the wash chamber 24 until the rear wheels
144 are aligned with the access openings 114 and lifts the frame
44, such as by pivoting the frame 44, to thereby lift the rear
wheels 144 through the access openings 114 and disconnect the frame
44 from the slides 42.
[0046] An alternative slide 42' is illustrated in FIG. 12, where
components similar to those of the first embodiment slide 42 are
identified with the same numeral bearing a prime (') symbol. The
slide 42' is substantially identical to the first embodiment slide
42, except that the track 100' does not include the front flange
stops 108, and the upper and the lower flanges 104', 106' extend
all the way to the end of the track 100'. As a result, the access
opening 114' is defined between the ends of the upper and lower
flanges 104', 106', and the closure 120' in the closed position
functions as the stop while blocking the access opening 114'.
[0047] Alternatively, the access opening 114 can be located
elsewhere in the track 100. For example, the access opening 114 can
be formed between the lower flange 106 and the front flange stop
108 if the lower flange 106 is sufficiently spaced from the front
end of the track 100.
[0048] An alternative embodiment of slides 200 is illustrated in
FIG. 13. The slides 200 are shown in FIG. 13 in conjunction with
the second utensil rack 30; however, it is within the scope of the
invention to utilize the slides 200 with the first utensil rack 28,
the third utensil rack 40, or any other utensil rack. The remaining
description of the slides 200 is presented with respect to one of
the slides 200, with it being understood that the description can
apply to both of the slides 200. A wheel support 202 couples the
slide 200 to a side of the second utensil rack 30.
[0049] Referring to FIG. 14, which is an exploded view of the slide
200 and the wheel support 202, the wheel support 202 carries a
front wheel 204 and a rear wheel 206 on a support plate 208. The
front wheel 204 and the rear wheel 206 of the illustrated
embodiment each include a circumferential groove 210. A wheel
support bracket 212 attached to the support plate 208 mounts the
wheel support 202 to the second utensil rack 30.
[0050] The slide 202 includes a rail 220 and a track 222 slidable
relative to the rail 202. The rail 220 includes a generally
vertical wall 224 having bracket retainers 226 that receive slide
brackets 228, which couple the rail 220 to one of the cabinet side
walls 18, 20. According to the illustrated embodiment, the bracket
retainers 226 fixedly couple the slide brackets 228 to the rail
220, and the bracket retainers 226 are fixedly coupled to the one
of the cabinet side walls 18, 20; thus, the rail 220 is fixedly
mounted to the one of the cabinet side walls 18, 20.
[0051] Referring now to FIG. 16, which is a perspective view of the
slide 200 the rail 220 further includes upper and lower flanges
230, 232 extending along the vertical wall 224 to define a rail
raceway 234. Each of the upper and lower flanges 230, 232 forms a
channel 236. The channel 236 in the upper flange 230 extends
upward, and the channel 236 formed in the lower flange 232 extends
downward; thus, the channels 236 extend away from the rail raceway
234. Further, the channels 236 extend along the entire length of
the upper and lower flanges 230, 232, except at the ends of the
upper and lower flanges 230, 232, where a projection 238 juts
downward and upward from the upper and lower flanges 230, 232,
respectively, into the rail raceway 234. The rail 220 further
includes a track stop 239 mounted to the vertical wall 224 and
protruding into the rail raceway 234.
[0052] The track 222 includes a generally vertical wall 240 with
upper and lower flanges 242, 244 that together define a track
raceway 246. Each of the upper and lower flanges 242, 244 forms a
channel 248. The channel 248 in the upper flange 242 extends
downward, and the channel 248 formed in the lower flange 232
extends upward; thus, the channels 248 extend towards the track
raceway 246. The channels 248 extend along the entire length of the
upper and lower flanges 242, 244, except at rear ends of the upper
and lower flanges 242, 244, where a projection 250 juts upward and
downward from the upper and lower flanges 242, 244, respectively,
away from the track raceway 246. The track raceway 246 terminates
at a front stop 252 and a rear stop 254 in the form of flanges at
ends of the track 222. The front stop 252 in the illustrated
embodiment is generally L-shaped. The upper flange 242 that
partially defines the track raceway 246 is spaced from the front
stop 252 to form an access opening 256 therebetween. The track 222
further includes a position limiter 258 formed in the vertical wall
240 and extending away from the track raceway 246
[0053] A closure 260 pivotally mounts to the track 222,
particularly to the upper and lower flanges 242, 244 of the track
222, and selectively blocks the access opening 256. The closure 260
includes parallel upper and lower walls 262, 264 joined by a side
wall 266 and a front wall 268 orthogonal to the side wall 266. The
side wall 266 and the front wall 268 form a grip 270 sized to be
grasped between a user's fingers for pivotally moving the closure
260. The closure 260 further includes a wheel retainer in the form
of a projection 274 depending from the upper wall 262 into the
track raceway 246. The closure 260 is movable between a closed
position (FIG. 20), where the upper wall 262 blocks the access
opening 256, and an opened position (FIG. 21), where the closure
260 is pivoted relative to the track 222 so that the upper wall 262
is spaced from the access opening 256. The closed and opened
positions will be described in more detail below. When the closure
260 is in the closed position, the projection 274 linearly aligns
with the channel 248 in the track upper flange 242.
[0054] A bearing assembly comprising a bearing cage 280 comprising
a plurality of ball bearings 282 slidably couples the track 222 and
rail 220 for relative slidable movement.
[0055] Referring to FIG. 15, when the slide 200 is assembled, the
rail raceway 234 receives the track 222 with the bearing assembly
positioned between the upper and lower flanges 230, 232 of the rail
220 and the upper and lower flanges 242, 244 of the track 222. In
particular, the bearing cage 280 sits between the channels 236 on
the rail 220 and the channels 248 on the track 222. The projections
238 at the ends of the channels 236 on the rail 220 retain the
bearing cage 280 in the rail raceway 234 (i.e., the projections 238
prevent the bearing cage 280 from sliding forwardly or rearwardly
out of the rail raceway 234). When the track 222 is coupled to the
wheel support 202 to couple the slide 200 to the second utensil
rack 30, the track raceway 246 receives the front and rear wheels
204, 206. The front and rear wheels 204, 206 are illustrated in
phantom in FIG. 15 to show the positioning of the front and rear
wheels 204, 206 within the track raceway 246. The grooves 210 on
the front and rear wheels 204, 206 receive the inwardly extending
channels 248 of the track upper and lower flanges 242, 244 such
that the front and rear wheels 204, 206 can roll along the channels
248, which act as a guide to facilitate retaining the front and
rear wheels 204, 206 in the track raceway 246.
[0056] An exemplary operation of the slide 200 will be described
with respect to FIGS. 15 and 17-21. It will be apparent to one of
ordinary skill that the operation can proceed in any logical order
and is not limited to the sequence presented below. The following
description is for illustrative purposes only and is not intended
to limit the invention in any way.
[0057] FIG. 15 illustrates the slide 200 in an initial position
with the front and rear wheels 204, 206 located as far rearwardly
as possible within the track raceway 246 and with the position
limiter 258 on the track 222 abutting the track stop 239 on the
rail 220 (not shown). This position coincides with the utensil rack
30 being completely received within the chamber 24 of the
dishwasher 10. The interaction between the position limiter 258 and
the track stop 239 prevents further rearward movement of the track
222 relative to the rail 220. In this position, a front end of the
track 222 and the closure 260 are both received within the rail
raceway 234. When the user desires to move the second utensil rack
30 relative to the cabinet 12, the user pulls the second utensil
rack 30 forwardly, and the front and rear wheels 204, 206
consequently roll forwardly in the track raceway 246 along the
channels 248 until the front wheel 204 abuts the front stop 252, as
shown in FIG. 17. When the front wheel 204 approaches the front
stop 252, the groove 210 on the front wheel 204 rolls off of the
channel 248 in the upper flange 242 and into engagement with
projection 274 on the closure 260. As the user continues to pull
the second utensil rack 30, the front wheel 204 transfers the
forward force to the track 222 via the front stop 252, and the
track 222 slides forwardly relative to the bearing cage 280 and the
rail 220 until the projections 250 on the track 222 abut a rear end
of the bearing cage 280, as illustrated in FIG. 18. As the user
continues to pull the second utensil rack 30, the track 222
transfers the forward force to the bearing cage 280 via the
projections 250, and the bearing cage 280 slides forwardly with the
track 222 relative to the rail 220 until the front end of the
bearing cage 280 abuts the projections 238 at the forward end of
the rail 220, as illustrated in FIG. 19. At this point, the slide
200 is at its most extended position relative to the cabinet 12 as
is the second utility rack 30.
[0058] When the slide 200 fully extends from the cabinet 12, as
shown in FIG. 19, or when the slide 200 is in any other position
where the front wheel 204 abuts or nearly abuts the front stop 252,
and the closure 260 is in the closed position blocking the access
opening 256, the groove 210 on the front wheel 204 receives the
projection 274 on the closure 260. FIG. 20, which is an enlarged
view of the region labeled XX in FIG. 19, best illustrates the
mating relationship between the front wheel 204 and the projection
274. The relationship between the front wheel 204 and the
projection 274 prevents lateral movement of the front wheel 204
relative to the track 222 and the track raceway 246. Thus, the
projection 274 prevents the front wheel 204 from popping out of the
track raceway 246 thereby avoiding accidental removal of the second
utensil basket 30 from the slide 220.
[0059] If the user desires to remove the second utensil rack 30
from the slide 200, the user moves the closure 260 from the closed
position of FIG. 20 to the opened position. Before the user can
move the closure 260, however, the user must ensure that the front
wheel 204 does not mate with the projection 274 on the closure 260.
If the front wheel 204 and the projection 274 mate, then the user
pushes the second utensil rack 30 rearward until at least the front
wheel 204 no longer engages the projection 274, as illustrated in
FIG. 21.
[0060] Once the front wheel 204 and the projection 274 no longer
mate, the user can move the closure to the opened position shown in
FIG. 21, such as by pivoting the closure 260 relative to the track
222. The closure 260 in the illustrated embodiment advantageously
remains mounted to the track 222 during movement between the closed
and opened positions and while in the opened position. Moving the
closure 260 spaces the upper wall 262 of the closure 262 from the
access opening 256 such that the user can thereafter pull the
second utensil rack 30 forwardly and upwardly through the access
opening 256, as indicated by an arrow in FIG. 21. The upward
movement of the second utensil rack 30 corresponds to lifting, such
as by pivoting, the second utensil rack 30 relative to the track
222. As a result of this configuration, the user must perform two
actions to remove the second utensil rack 30 from the slide 200.
The user first slides the second utensil rack 30 in a first
direction to align the front wheel 204 with the access opening 256
and then lifts the second utensil rack 30 in a second direction,
such as by pivoting, to move the front wheel 204 through the access
opening 256. The two actions can be performed in a sequential
fashion wherein the sliding and the lifting are distinct actions or
wherein the sliding and the lifting chronologically overlap (i.e.,
the lifting begins while the sliding is being executed). Requiring
movement of the second utility rack 30 in two different directions
facilitates accidental removal of the second utility rack 30 from
the slide 200.
[0061] After the front wheel 204 passes through the access opening
256, the user can continue to pull the second utensil rack 30
forwardly and upwardly to pass the rear wheel 206 through the
access opening 256 in the same manner. The second utensil rack 30
removed from the slide 200 can be mounted to the slide 200 and
pushed rearwardly into the cabinet 12 by repeating the above
procedure in a reverse order.
[0062] The alternative embodiment slides 200 can include features
described above with respect to the previous embodiment slides 42.
For example, the access opening 258 can be positioned between the
upper and lower flanges 242, 244 of the track 222. When the access
opening 258 is located between the upper and lower flanges 242,
244, the closure 260 can form the front stop for the front wheel
204. Furthermore, the closure 260 can include a detent that mates
with an aperture on the track 222 for retaining the closure 260 in
the closed position. Additionally, the closure need not have the
projection 274, which would eliminate the need to back up the
utensil rack 30 prior to opening the closure 260.
[0063] Another alternative embodiment slide 200 is illustrated in
FIG. 22. The slide 200 is identical to the embodiment of the slides
200 shown in FIGS. 13-21, except that the slide 200 of FIG. 22 does
not include the closure 260, and the access opening 256 in the
track upper flange 222 is spaced from the front stop 252. The
access opening 256 can be spaced from the front stop 252 any
suitable distance. For example, the access opening 256 can be
spaced from the front stop 252 a distance at least equal to a
diameter of the front wheel 204, as illustrated in FIG. 22.
[0064] The operation of the slide 200 of FIG. 22 is substantially
identical to the operation of the slides 200 of FIG. 13-21, except
for the portion related to removal of the front wheel 204 from the
track raceway 246. To remove the front wheel 204 from the track
raceway 246, the user first aligns the front wheel 204 with the
access opening 256. If the front wheel 204 is positioned adjacent
to the front stop 252, the user must slide the front wheel 204
rearward to align the front wheel 204 with the access opening 204.
Next, the user lifts the front wheel 204, such as by pivoting the
second utensil rack 30, through the access opening 256. After the
front wheel 204 passes through the access opening 256, the user can
pull the second utensil rack 30 forwardly and upwardly to pass the
rear wheel 206 through the access opening 256 in the same
manner.
[0065] Spacing the access opening 256 from the front stop 252
requires the user to purposely slide the second utensil rack 30
rearward prior to moving the front wheel 204 through the access
opening 256. Requiring the rearward movement helps to prevent
accidental removal of the front wheel 204 from the track raceway
246 when the slide 200 does not include the closure 260 for
selectively closing the access opening 256. However, it is within
the scope of the invention for the access opening 256 to be located
in any suitable position, such as directly adjacent to the front
stop 252, as is shown with respect to the embodiments of FIGS. 11
and 21.
[0066] Furthermore, the track raceway 246 of the illustrated
embodiment and the other embodiments of the slides can be
substantially unobstructed such that the front wheel 204 can freely
slide along the track raceway 246 to the access opening 256. In
other words, there are no detents or other structures to impede
movement of the front wheel 204 within the track raceway 246. The
positioning of the access opening 256 and the employment of the
closure 260, either alone or in combination with one another, are
sufficient to control the movement of the front wheel 204 and the
removal of the front wheel 204 from the slide 200, thereby negating
a need for detents or other structures.
[0067] The complementary basket elements 46A, 46B have been
described with respect to the number, shape, and size shown in the
figures. However, it is within the scope of the invention for the
whole basket to be formed by more than two basket elements and for
the basket elements to be shaped and sized in any suitable manner
as long as they are complementary and together form the whole
basket. For example, the whole basket can be formed by two or more
rectangular basket elements having straight edges, a first L-shaped
basket element and a second square or rectangular basket element,
two triangular basket elements, or basket elements similar to the
basket elements 46A, 46B but having a fourth edge 70D with a
different contour. Additionally, the basket elements 46A, 46B are
not limited to use with the frame 44; the basket elements 46A, 46B
can be utilized with any suitable frame or utensil rack and are not
required to be vertically adjustable within the wash chamber 24.
Similarly, the frame 44 can mount a unitary whole basket rather
than separate basket elements so that the unitary whole basket is
vertically adjustable within the wash chamber 24.
[0068] While the third utensil rack 40 has been shown and described
as being located near the upper wall 14 of the cabinet 12 and in
conjunction with the first and the second utensil racks 28, 30, it
is within the scope of the invention to utilize the third utensil
rack 40 in any location within the wash chamber 24, such as
adjacent the lower wall 16 or in the middle of the wash chamber 24,
and with or without other utensil racks. Furthermore, the slides 42
are not limited for use with the third utensil rack 40; rather, the
slides 42 can be used with the first utensil rack 28, the second
utensil rack 30, or any other suitable utensil rack.
[0069] The grid of the basket elements 46A, 46B has been described
as being formed by the plurality of intersecting ribs 72; however,
it is within the scope of the invention for the grid to be formed
by other structures having apertures or gaps that allow wash liquid
to pass through the bottom wall of the basket elements 46A, 46B.
For example, the grid can be a molded panel with circular,
rectangular, or other shaped apertures formed therein.
[0070] While the third utensil rack 40 and the slides 42 have been
described and shown as for use in the dishwasher 10 comprising the
cabinet 12 and the door 26 movably mounted to the cabinet 12, the
dishwasher 10 can be any type of appliance for washing dishes and
is not limited to the dishwasher 10 shown in the figures. For
example, the dishwasher can be a drawer-type dishwasher, wherein
the wash chamber is formed in an open-top drawer that is slidably
mounted to a cabinet. Further, the slides 42 can be used to
slidably mount the drawer to the cabinet, if desired.
[0071] The third utensil rack 40 accommodates various shapes and
sizes of utensils for effective cleaning thereof without
dramatically sacrificing capacity of the first and second utensil
racks 28, 30. Because the basket elements 46A, 46B are vertically
adjustable, the third utensil rack 40 can be arranged to
accommodate the sizes of utensils in the second utensil rack 30. In
the preferred embodiment, various portions of the frame 44, such as
the upper support rails 62, 63 and the lower support rails 64, 66,
function as height adjusters for adjustably mounting the basket
elements 46A, 46B to the frame 44. However, the height adjusters
can also be located on the basket elements 46A, 46B. For example,
the basket elements 46A, 46B can include multiple hooks vertically
spaced on the peripheral wall 70 such that the basket elements 46A,
46B can be mounted to a portion of the frame 44 in different
vertical orientations depending on which hooks mate with the
portion of the frame 44.
[0072] While the invention has been specifically described in
connection with certain specific embodiments thereof, it is to be
understood that this is by way of illustration and not of
limitation, and the scope of the appended claims should be
construed as broadly as the prior art will permit.
