Abstract
Abstract An offset cantilevered support leg for a height adjustable desk which resists lateral forces is provided. Each support leg is connected to the underside of the desk top at the lateral ends thereof by an L-shaped bracket. A primary support arm provides the cantilevered support for the desk top while a secondary support arm, angularly offset from and generally oriented perpendicularly with respect to the primary support arm, provides support against lateral forces directed against the legs. By orienting each of the respective support arms of the L-shaped bracket with the rear corners of the work surface, the legs provide adequate support against vertical and horizontal loading while maximizing the available space underneath the desk, and thus eliminating the need for a horizontal stretcher between the cantilevered support leg.
