  • Shelf height adjuster of refrigerator
    Patent number: 7178890
    Abstract: The present invention relates to a shelf height adjuster of a refrigerator. According to the present invention, gear portions 12 are vertically formed on both side surfaces on a refrigerating chamber of the refrigerator. Height adjustment gears 22 which are engaged with the gear portions 12 are rotatably installed in opposite sides of a shelf 20, respectively. Each stopper 30 for regulating the rotation of each height adjustment gear is engaged to the height adjustment gear 22 by means of a spring 32, and thus, it causes the height adjustment gear 22 not to rotate. When the height of shelf is adjusted, the height adjustment gears 22 are made freely rotate by releasing the stoppers 30 from the height adjustment gears 22, and thus, the height of the shelf may be adjusted without taking out the shelf from the refrigerator.
