Abstract: A dish rack is supported for vertical movement relative to a dishwasher tub between lowered and raised positions. To raise the rack, spring biased locking levers provided on side walls of the dish rack are pivoted to cause wing members of the locking levers to release locking tabs, extending in a cantilevered fashion from locking straps secured to the rack, from locking openings provided in adjuster arms which are fixed vertically relative to the tub, thereby disengaging the locking straps from the adjuster arms to enable the rack to be lifted to the raised position. To lower the rack, the locking levers are again pivoted to reposition support members of the locking straps into positions offset from the adjuster arms, thereby enabling the rack to be guided to the lowered position where the locking tabs automatically engage the adjuster arms.

Abstract: Disclosed is a dishwasher having an interior with a tub, a dish rack slidably attached to the tub, the dish rack having a plurality of vertically-oriented side rails, and a height adjustment system including first and second height adjustment mechanisms provided alongside walls of the dish rack for vertically shifting the dish rack between lowered and raised positions relative to the tub. Each of first and second height adjustment mechanisms includes an adjuster arm fixed vertically relative to the tub, having at least one locking boss at the first end, and a locking clip on the adjuster arm having at least one locking tab adapted to couple with the locking boss to prevent the rack from shifting vertically relative to the adjuster arm. The locking clip has a pair of interference ribs engaging a pair of side rails to prevent rotational movement of the rack with respect to the dishwasher.

Abstract: A rack assembly for an automatic dishwasher having opposing side portions, at least two axles extending outwardly from each of the opposing side portions, and a roller wheel mounted to each axle. Each roller wheel roller wheel has a hub adapted to be fixedly attached to the axle, and a wheel rotatably mounted to the hub. A plurality of separators that define pockets is integrally molded with one of the hub or the wheel. Each pocket is adapted to contain one ball bearing such that no two adjacent ball bearings make contact.

Abstract: An apparatus for the rack assembly of a dishwasher that includes opposing side portions, at least two axles extending outwardly from each of the opposing side portions, and a roller wheel mounted to each axle, wherein each roller wheel has ball bearings that enable at least a portion of the roller wheel to rotate about the axle. The rack assembly apparatus may be used for the upper or lower rack of the dishwasher. In case of the lower rack, the assembly may roll on the surface of the door. In case of the upper rack, the assembly may roll along guide rails.

Abstract translation: 托盘支撑在相对于洗碗机桶的下降和升高位置之间的垂直运动。 为了升高机架，设置在餐具架的侧壁上的弹簧偏压锁定杆枢转以使得锁定杆的翼部件能够以悬臂方式从固定在机架上的锁定带伸出， 调节器臂相对于桶垂直地固定，从而使锁定带与调节臂分离，使得齿条能够提升到升高位置。 为了降低机架，锁定杆再次枢转以将锁定带的支撑构件重新定位到偏离调节臂的位置，从而使得齿条能够被引导到下降位置，在该位置处锁定片自动地接合调节臂。
