  "title": "How Dishwasher Racks Use Articulating Skis to Glide Smoothly",
  "original_title": "Articulating ski assembly for a lower rack of a dishwashing appliance",
  "summary": "A mechanical assembly for dishwasher racks that uses a pivoting ski foot to help the rack slide over obstacles or transitions without getting stuck.",
  "what_it_does": "This patent describes a specialized 'ski' attachment for the bottom of a dishwasher rack. The assembly uses a hub and articulation ring to allow the ski foot to pivot or tilt, helping the rack glide over the gap between the dishwasher tub and the door or over uneven tracks. It includes specific suspension arms that dampen movement, ensuring the rack doesn't jerk or jam when it hits a transition point. The tip and tail of the ski feature a serpentine design, which provides flexibility and structural support during the articulation process.",
  "what_it_does_not_cover": [
    "Does not cover fixed, non-pivoting rack wheels or rollers.",
    "Does not cover motorized or powered rack movement systems.",
    "Does not cover rack designs that rely solely on ball-bearing slides.",
    "Does not cover the internal plumbing or spray arm mechanisms of the dishwasher."

  "abstract": "An articulating ski assembly for a lower rack of a dishwashing appliance may include a ski bracket attached to the lower rack assembly. The articulating ski assembly may also include a hub that may extend from the ski bracket. The articulating ski assembly may further include a ski. The ski may include an articulation ring attached to the hub to provide an articulation joint for the ski. The ski may further include a base, a tip, and a tail. The base may be positioned at a bottom of the articulation ring. The tip may extend transversely from a first end of the base. The tail may extend transversely from a second end of the base.",
