  • Patent number: 5809797
    Abstract: An ice cube tray assembly for refrigerators, which prevents an undesirable separation of the ice cube tray from the tray case when the tray is rotated, is disclosed. The tray assembly of this invention has a tray case, which is slidably installed in a base of a freezer compartment of a refrigerator and has a bearing with a snap lip. An ice cube tray is rotatably mounted to the case by a hinge pin snapping into the bearing. A stopper is provided on the bearing for preventing an undesirable separation of the hinge pin from the bearing when the tray is rotated. The tray assembly is thus free from any locking device used for preventing separation of the tray so that the assembly has a simple construction, improves work efficiency while assembling the tray assembly, and improves the operational reliability of the refrigerators.

  • Patent number: 5788094
    Abstract: A shelf construction in a refrigerator includes a pair of guide rails provided on opposite side walls of a refrigerator compartment. A shelf slides forwardly and rearwardly along the guide rails. Two front stop beads are provided at respective front portions of the guide rails, and two rear stop beads are provided at respective rear portions of the guide rails. Stoppers project from the shelf in an area bordered by the front and rear stop beads. The stoppers come into contact with the front beads as the shelf slides forwardly, thereby limiting the forward movement of the shelf. The stoppers also come into contact with the rear beads as the shelf slides rearwardly, thereby limiting the rearward movement of the shelf.
