Patent attributes
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. The door supporting device further comprises a hinge cap fitted around the upper end of the hinge shaft and inserted into a hinge hole formed in a bottom surface of the door so as to rotatably support the door. The hinge cap comprises a rearward extension and a rotation preventing projection extending downward from the extension, and the rotation preventing projection is inserted into a fixing hole of the hinge bracket so as to restrict rotation of the hinge cap.
