ABSTRACT:
A work desk has an adjustable height working surface that is raised by a force applied by a lockable gas spring via a first pulley system. The first pulley system doubles the travel of the working surface as compared with the travel of the piston of the gas spring. A second pulley system ensures that all parts of the working surface are raised by an equal amount. Four slides guide the movement of the working surface. The combination of the slides and second pulley system allows the working surface to be closely held with a minimum of lateral or vertical play when the gas spring is locked. The first pulley system, in conjunction with a commercially available gas spring, the travel of whose piston is limited to 71/2 inches (190 mm), permits a vertical travel of 15 inches (380 mm) for the working surface. This travel is adequate to permit a broad range of operators to use the work desk while working in either a sitting or a standing position.
