    • A table (10) includes telescoping legs (14, 16), each of which has a stationary member (18, 114) and a sliding member (102) which are adapted for vertical travel relative to each other. A work surface (20) is mounted for vertical travel with the sliding members (102). The table (10) includes a height adjustment means including a drive mechanism (70) which causes the sliding leg member (102) to move vertically relative to the stationary leg member (18, 114). Supported on the frame and operatively connected between the drive mechanism (70) and sliding leg member (102) are levers (82). The levers (82) are pivotably mounted to a skirt (26) for rotation about the center portions thereof and rotate through a selected arc when the drive mechanism (70) is actuated. Rotation of the levers (82) by the drive mechanism (70) causes the sliding members (102) of the legs (14, 16) to be displaced vertically and carry with it the work surface ( 20).
    • 桌子(10)包括伸缩腿部(14,16),每个腿部具有适于相对于彼此垂直行进的固定构件(18,114)和滑动构件(102)。 安装工作表面(20)用于与滑动构件(102)垂直行进。 工作台(10)包括一个高度调节装置,包括一个驱动机构(70),该驱动机构使滑动腿部件相对于静止的腿部构件垂直移动。 在框架上支撑并且可操作地连接在驱动机构(70)和滑动腿部件(102)之间的是杠杆(82)。 杠杆(82)可枢转地安装到裙部(26)上,以在驱动机构(70)被致动时围绕其中心部分旋转并旋转通过选定的弧。 通过驱动机构(70)使杆(82)的旋转使得腿部(14,16)的滑动构件(102)垂直移动并且将其与工作表面(20)一起携带。
