  • Patent number: 6604800
    Abstract: A refrigerator shelf includes a glass platform having an encapsulating rim which is integrally formed with a pair of downwardly extending wing members, each having a transverse threaded hole formed therein. A projection member, including an elongated shaft having a threaded section spaced from a tip portion, is provided for each wing member. The threaded section is threadably received in the hole of a respective wing member. The shelf is adapted to be slidably supported upon side wall rails of a refrigerator liner, with the tip portion of each projection member extending beneath a respective one of the rails, thereby preventing tipping of the shelf. The tip portion is also adapted to engage structure on the rail in order to limit the permissible degree of sliding movement of the shelf along the rails.
