ABSTRACT:
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).
