Abstract

A dishwasher rack assembly includes a bottom wall formed of a first set of spaced apart rods crossed by a second set of spaced apart rods to define an open lattice structure. At least one channel member is attached to respective one the rods. A plurality of tines are received within the channel member and are variably positional along the channel member so as to adjust spacing between the tines without adjusting the channel member relative to the rod.

Claims

1. A dishwasher rack assembly, comprising:

a bottom wall formed of a first set of spaced apart rods crossed by a second set of spaced apart rods to define an open lattice structure;

a pair of channel members spaced from each other and attached to different ones of said rods;

a plurality of U-shaped tine members having a bridge between opposite tines, said bridge extending between said channel members and said tines received within said channel member, wherein said tine members are variably positionable along said channel members by movement of said tine members relative to said channel members; and

wherein said channel members comprise a top groove through which said tines project and a side groove that accommodates sliding movement of said bridge alone said channel members.

2. The dishwasher rack assembly as in claim 1, wherein said channel member defines a top groove, said tines being infinitely positionable along said top groove, said top groove defining a friction fit with said tines that holds said tines in an upright orientation within said channel members.

3. The dishwasher rack assembly as in claim 1, wherein said channel member defines vertically oriented discrete tine locations along the length thereof, said tine locations comprising an engagement profile that holds said tines in an upright orientation within said channel member.

4. The dishwasher rack assembly as in claim 1, wherein said top groove defines a plurality of discrete tine locations along the length thereof, said tine locations comprising an engagement profile that holds said tines in an upright orientation within said channel members.

5. The dishwasher rack assembly as in claim 1, wherein said tines are infinitely positionable to any location along said top groove, said top groove defining a friction fit with said tines that holds said tines in an upright orientation within said channel members.

6. The dishwasher rack assembly as in claim 1, wherein said pair of channel members define vertically oriented discrete tine locations along the length thereof, said tine locations comprising an engagement profile that holds said tines in an upright orientation within said channel members, said tines adjustable along said channel members upon flexing of said tines inwardly to disengage said tines from said tine locations.

7. The dishwasher rack assembly as in claim 1, wherein said pair of channel members comprise a plurality of discrete horizontally oriented bridge locations defined along the length thereof, said tine members movable into and out of said bridge locations.

8. The dishwasher rack assembly as in claim 7, wherein said bridge locations are defined in a top surface of said channel members and comprise a cross-sectional shape that engages a complimentary-shaped section of said bridge that holds said tines in an upright orientation within said channel members.

9. The dishwasher rack assembly as in claim 8, wherein said bridge is rotatable within said bridge locations such that said tines are rotatable to a down position wherein said tines lie across said rod members.

10. The dishwasher rack assembly as in claim 1, wherein said channel members comprise a plurality of discrete tine locations along the length thereof, said tines insertable into said tine locations.

11. The dishwasher rack assembly as in claim 10, wherein said tines comprise a stepped-profile insertion end that is insertable into vertically oriented receipt holes at said respective tine locations to hold said tines in an upright orientation within said channel members.

12. The dishwasher rack assembly as in claim 1, wherein said rack assembly is a bottom rack assembly for a dishwasher.
