Abstract: A top-supported sliding door system or a vertically sliding door system achieves an enhanced air seal with a lateral keeper mechanism on either or both of the trailing and leading edges. On an outward lateral edge of a door panel, a keeper projects inwardly toward the door frame to engage a door frame camming surface such as a pin. The bracket may advantageously disengage under a force indicative of impact in order to minimize damage resulting therefrom. Application of the lateral keeper mechanism may further be used on vertically sliding doors and on multi-panel horizontal sliding doors. In addition, a rail may extend from the angled pin to engage the keeper throughout the full travel of the door panel.

Abstract: A sliding door capable of permitting both initiation of a door opening operation and termination of a door closing operation to be smoothly and readily accomplished. During the door closing operation, obliquely downward and inward movement of a door body and an action of a link cooperate with each other to permit the door body to be pressedly contacted with an outer wall surface of an object such as a refrigerator using substantially reduced force. During the door opening operation, upward outward movement of the door body and an action of the link permit the door body to be readily released from the outer wall surface using significantly reduced force.
