Dishrack motion control arrangement for a dishwasher

A motion control apparatus for stabilizing the motion of a dishrack mounted within a cavity formed by a tub of a dishwasher, said apparatus preventing yawing of said dishrack relative to said tub during horizontal movement of said dishrack in and out of said tub, said motion control apparatus comprising:

• a torque shaft disposed transversely within said tub;
• a pair of gear wheels keyed to opposite ends of said torque shaft for rotating together;
• a pair of gear tracks integrally formed into a top inner surface of said tub and extending in the direction of dishrack movement within said tub;
• mounting means for supporting said dishrack within said cavity of said tub such that said dishrack is supported within said tub and allowed in and out movement within said tub, said mounting means further including means for rotabably supporting said torque shaft such that said gear wheels are operatively meshed with said gear tracks during said in and out movement of said dishrack within said tub.

• a torque shaft disposed transversely within said tub;
• a plurality of gear wheels rigidly interconnected with said torque shaft for rotating together;
• a plurality of gear tracks interconnected with said tub;
• and
• mounting means for supporting said dishrack within said cavity of said tub such that said dishrack is supported within said tub and allowed in and out movement within said tub, said mounting means further having a vertical extension portion for rotatably supporting said torque shaft such that said gear wheels are operatively meshed with said gear tracks during said in and out movement of said dishrack within said tub, said mounting means further including:
• a plurality of rollers rotatably interconnected with said tub;
• a pair of tracks disposed between said rollers and supported by said rollers for longitudinal movement;
• and
• a carrier arm having a plurality of wheels rotatably interconnected with said carrier arm, said wheels being received in said tracks such that said carrier arm moveably supports said dishrack within said tub, said vertical extension portion extending from said carrier arm.
