Abstract
The device for positioning a video display unit (VDU) comprises a supporting structure with a spherical cap provided at the bottom of the supporting structure, and a base with a frusto-conical seat for housing the spherical cap. The center of gravity of the VDU coincides substantially with the center of the spherical cap, and the base comprises a central pin projecting into a slot in the cap. This connection of pin and slot type enables the video unit to rotate in a vertical plane passing through the slot axis and in a horizontal plane perpendicular to the pin axis. One or more spacer rings complete with seat and pin can be stacked on the base to raise the VDU.
