US Patent 6857610 Position adjustable load support mechanism

An improved mechanism for positioning loads of varying magnitudes, such as LCD displays, etc. The position of the load can be varied in height and angle according to the requirements of the user. The mechanism incorporates an adjustable sliding fulcrum, a support arm, a housing with four generally perpendicular channels, and a gas spring. The mechanism is initially manually adjusted for a particular load and then it automatically adjusts proportionally for the varying moments generated as the position of the load changes. The load is therefore evenly counterbalanced throughout its range of motion, and its position is maintained.
