ABSTRACT:
Support device for a liquid crystal flat screen (12), in particular for computer workstations, of the type including an arm (14) and an articulating mechanism (18) interposed between the arm and the screen. The articulating mechanism (18) includes a ball (36) having a general hemispherical shape (38) and adapted to be fixed to the screen (12), a cage (46) defining a housing (48) for receiving the ball and having an annular edge (50) which makes frictional contact with the ball, a tie rod (64) interposed between the cage (46) and the ball (36), while resting substantially at the center (C) of the ball, to exert an elastic restoring force of a selected value which causes the ball to rest against the annular edge of the cage, and a tie rod passage (74) formed of a widened recess produced in the ball (36) and opening on the hemispherical surface (38) of the ball to allow clearance of the tie rod in the ball, whatever the position of the ball with respect to the cage.
