The arm unit has a holder for support of the display device and the foot part (12) on its under side has partly a component (20) of a low friction type, partly a component (22) of a high friction type. The high friction component is arranged on the one lever (28) of a two-armed lever arrangement. In the foot part (12) is located a rocker arm movably arranged between a first normal usage position in which it is held in friction location against the underlying table surface, and a second position in which it is raised from the table surface, so that the foot part rests only on the low friction component (20). The second lever (34) in the rocker arm is formed with a handgrip (38) by means of which the rocker arm can be pivoted around an axis (26) to raise the high friction component (22) and the frame (12) normally located against the table surface. |
