  • Patent number: 5282593
    Abstract: An adjustable leg for tables and other platforms includes elevating mechanism in the form of a plurality of screw members which are appropriately rotated and also includes rotation preventing mechanism telescopingly extending through the hollow portion of the screw members to hold the lower screw member non-rotatable so that the leg can move in extension and retraction. In this way, the leg solves the problem of having a sufficiently low elevation for the table when the legs are retracted and a sufficiently high elevation for the table when the legs are extended.
