ABSTRACT:
Provided is a vertically adjustable desk lifting device having a plurality of gas pressurized cylinders for urging a desk in an upward direction, thereby facilitating the raising and lowering of a desk by a single user. The desk can be locked into a multitude of vertical positions and easily released via a foot pedal. The lifting device comprises a pair of spaced-apart gas pressurized cylinders positioned on both sides of a desk. The gas pressurized cylinders are chosen or calibrated to provide an adequate upward force to slightly urge the desk in the upward direction, depending upon the weight of the desk and the distribution of such weight. Additional gas pressurized cylinders can be easily inserted adjacent any one of the four standard gas pressurized cylinders to counterbalance the weight distribution of the desk if needed. Positioned between the two gas pressurized cylinders is a locking mechanism, comprising telescoping cylindrical members and a hinged-pin and spring arrangement, for stabilizing and securing the desk in a desired vertical position. A foot pedal and cables are provided to release the locking mechanism.
