Abstract
A method is provided for supporting a load such as a computer terminal by balancing the load with two opposed parallel forces of different magnitudes which are algebraically added with the weight of the load to result in a gravitationally neutral or statically stable (or dynamically stable) condition whereby the load remains in any position to which displaced and whereby displacement of the load can be effected with ease. There is provided an apparatus for accomplishing the aforegoing which employs a lever for engaging the load for multi-dimensional adjustment to a selected spatial position. A first gravitational control engages the lever and counteracts the weight of the load with a force in excess of that necessary to balance the load. A second gravitational control also engages the lever and counteracts the aforesaid force with a force such that the weight of the load in conjunction with the force of the second gravitational control counterbalances the force of the first gravitational control to provide the aforesaid neutral gravitational neutral condition.
