Abstract
An arrangement for stabilizing the in and out movement of a dishwasher dishrack which produces a precise guidance of the rack during its movement, including a stabilizer axle mounted to the rack and extending normally to the direction of movement. Friction rollers are fixed at either end of the stabilizer axle, spring-biased into engagement with an interior surface of the dishwasher cabinet, the constrained simultaneous rotation of each wheel serving to precisely control the movement and attitude of the rack during in and out movement. The spring-bias also preloads the rack mounting components to provide a vertical stabilizing effect. The stabilizer axle is mounted to specially configured rear corner brackets, housing spring-biased plungers which rotatably mount the axle, while producing the upward biasing thereof.
