A mounting arrangement for a planar visual display unit includes a support base, which can be fixed to a support surface, spacer tubes for elevating a pivotable base above the support surface and an arm fixed to the base through a hinge pin and an air spring. The arm supports a shaped channel plate for holding the visual display unit when the visual display unit is attached to a complementary mounting bracket. The pivot base can rotate 360° with respect to the support base and the arm can move in a vertical plane limited by the action of an air spring. The shaped channel plate is attached to the arm by a pin pivot and a ball and socket joint. The arm and the visual display unit maintain a steady position by way of the dampening of the air spring and the frictional loading applied to each of the joint components, namely the hinge pin, and the pin pivot and ball and socket joint attaching the plate to the arm. |
