  • 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.
  • 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.

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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • utensils of different length can be efficiently arranged within the basket elements 46A, 46B.
  • relatively short utensils A such as standard forks and spoons
  • medium length utensils B such as table knives
  • 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.
  • the utensils can be placed in any suitable location of the basket elements 46A, 46B.
  • the relatively short utensils A can be placed in the second basket element portion 78, if desired.
  • 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.
  • 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).
  • the tines 88 are preferably arranged in pairs of tines to form two parallel rows 88A, 88B of tines 88.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • the basket elements 46A, 46B can be vertically adjustable on the frame 44 and, therefore, within the wash chamber 24.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the slide mount can comprise one or more wheels mounted to the side walls 18, 20.

  • 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.
  • 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 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.
  • the third utensil rack 40 is thereby mounted to the dishwasher 10 and can slide relative to the wash chamber 24.
  • 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.

  • 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.
  • 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.
  • the alternative embodiment slides 200 can include features described above with respect to the previous embodiment slides 42.
  • the access opening 258 can be positioned between the upper and lower flanges 242, 244 of the track 222.

  • 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.
  • FIG. 22 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.
  • 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.
  • 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.
  • the user 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.
  • 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.
  • the access opening 256 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.
  • the access opening 256 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.
