  • Patent number: 8166611
    Abstract: The present invention relates to a door supporting device for a refrigerator. The door supporting device of the present invention can adjust the height of the door. A hinge bracket of the door supporting device of the present invention includes a fixing portion fixed to a front face of the refrigerator, and a supporting portion extending forward from an upper end of the fixing portion and having a threaded hole with threads formed on an inner periphery thereof. A hinge shaft of the door supporting device has threads on an outer periphery thereof and is threadly engaged with the threaded hole so that the hinge shaft can be supported by the hinge bracket. An upper end of the hinge shaft rotatably supports the door. The height of the door can be adjusted by rotating the hinge shaft. A nut is threadly engaged with the hinge shaft below the hinge bracket. The nut prevents the hinge shaft from being rotated so that the door can be constantly maintained at a predetermined height.

  • Patent number: 7752709
    Abstract: Disclosed is a refrigerator having a height-adjustable door. The body of the refrigerator has at least one storage space having a front opening. The door is coupled to the body so as to cover/uncover the storage space, and a hinge hole is formed on the bottom surface of the door. A hinge frame is fixed to a front surface of a lower portion of the body and has a hinge shaft inserted into the hinge hole so as to rotatably support the door. The hinge shaft is covered with a hinge bush, a part of which is inserted into the hinge hole. The hinge bush has a flange portion on its lower end for supporting the bottom surface of the door. A height adjustment screw is screw-coupled to a screw hole of the hinge frame so as to travel vertically. The upper end of the height adjustment screw abuts the bottom surface of the hinge bush so that, when rotated, the height adjustment screw lifts/lowers the hinge bush, in order to adjust the height of the door.
