A support device for a liquid crystal flat screen (12) comprising an arm (14) and an articulating mechanism (18) which is disposed in between the arm (14) and the screen (12). The articulating mechanism (18) comprises a ball element (38) having a surface which is generally hemispherical in form (38) and which can be fixed to the screen, a cage (46) defining a housing (48) for receiving the ball (36), and traction means which are disposed in between the cage and the ball, essentially resting on the center of the ball in order to exert an elastic spring force of a chosen value, which causes the ball (38) to rest against the annular edge (50) of the cage. The invention is especially suitable for use in workstations. |
