摘要： 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.
摘要翻译：桌面的高度和角度可以独立调节，最小化为手动力，从而方便残疾人或残疾人使用桌子。桌子上设有一个扭力杆，大大简化了高度调节，并具有一个平行的杠杆臂结构，允许这种调整而不改变台面的角度。桌面的高度和倾斜角度均通过一对锯齿状的互锁盘牢固地固定，这些盘是弹簧加载的，以便只需几匝调节手柄即可轻易地锁定或解锁桌面。此外，摩擦垫圈与该弹簧加载一起使用，以便即使在盘被解锁之后基本保持桌面的位置，进一步促进受到体力受损的人的角度和高度调节。桌子的设计和适当的尺寸适于容纳轮椅，桌面上设有可拆卸的夹具和凸起的周边边缘，以防止书本，纸张，书写工具等脱落。
