ABSTRACT:
A support assembly in which a standard and a support bracket are provided with interengaging components for securing the support bracket in a selected vertical position relative to the standard. The standard has two opposed, spaced surfaces between which are received a pair of locking tabs projecting from one side of the support bracket. Each locking tab is generally rectangular in cross section and is angled to present a sharp horizontally extending corner. When these locking tabs are positioned between the faces of the standard, and the free end of the support bracket is tilted downwardly, the upper latching tab moves toward and bites into a pair of ribs projecting from one of the opposed surfaces while the lower latching tab moves in the opposite direction to bite into a pair of projecting ribs from the opposite surface. When this occurs, the support bracket is fixed relative to the standard. The locking relationship permits the support bracket to be continuously vertically adjustable relative to the standard.
