摘要： A height adjustable desk including a work bench which is height adjustable and supported upon a pair of upwardly extending legs. The leg includes an upper portion supported on a lower portion. A height adjustment mechanism is manipulated by the user to adjust the height of the upper portion. This motion is transferred to the upper portion of the leg by means of cooperating rack gears meshingly engaged with their associated pinion gears. A shaft couples the gears so that the upper portions move in unison. The height adjustment mechanism includes a cooperating worm gear and nut. The worm gear is supported by the upper portion, while the nut is mounted in the lower portion.

摘要： A frame for a desk to support a work surface for height adjustment of the work surface. The frame includes a base frame consisting of a pair of vertical members which are generally parallel, co-extensive and transversely spaced. The vertical members of the base frame receive a pair of vertical members of a height adjustable sub frame. A rotatably driven first shaft causes vertical movement of an associated pair of vertical members on one side of the desk while vertical movement is transferred to the other side of the desk by a second shaft having gears which engage a rack gear on each of the vertical members of the sub-frame.
摘要翻译：用于桌面的框架，用于支撑工作表面，用于工作表面的高度调节。框架包括由一对垂直构件构成的基架，该垂直构件大致平行，共同且横向间隔开。基架的垂直构件接收高度可调节子框架的一对垂直构件。旋转驱动的第一轴使得相关联的一对垂直构件在桌子的一侧上垂直移动，同时垂直运动通过具有齿轮的第二轴传递到桌子的另一侧，该第二轴具有接合每个垂直构件上的齿条的子框架。
