Abstract

The elevation and angle of a desk top are independently adjustable with the exertion of a minimum of manual force, thereby facilitating the use of the desk by handicapped or disabled persons. The desk is provided with a torsion bar to substantially ease elevational adjustments and with a parallel lever arm construction which permits such adjustments without changing the angle of the desk top. The height and tilt angle of the desk top are each securely fixed by means of a pair of serrated, interlocking discs which are spring loaded to permit them to be easily locked or unlocked with only a few turns of an adjustment handle. In addition, frictional washers are utilized in conjunction with this spring loading to substantially maintain the position of the desk top even after the discs are unlocked, further facilitating angular and elevational adjustments by persons of impaired physical strength. The desk is designed and suitably dimensioned to accommodate a wheel chair, and the desk top is provided with a removable clamp and a raised peripheral edge to prevent books, paper, writing utensils and the like from falling off.
