Abstract
In a table (11), the tabletop (19) is divided into three parts (21, 22, 23), of which one (23) is fixedly connected to the frame (13) of the table (11), the second (22) is articulated on the first (23) by a joint (27) and the third (31) is in turn articulated on the second (22) by joint (25) and is adjustable as to height. Together with an arm (29) pivotally fixed on the frame (13) and on the height-adjustable tabletop part (21), the movable tabletop part (22, 21) and the frame (13) form a parallelogram. The angle .alpha. of the parallelogram is adjustable with a lever (31) on the middle tabletop part (22) and by a motor (33) with a spindle (35). The height of the table is thus adjustable.
