<p>The temporary fixing for a display panel on a road sign frame has the panel mounted for vertical sliding in guides (13a,b) mounted on a cross beam (4) of the frame. The cross beam has electrical actuators to selectively move the panel up and down from a lowered position with the lower panel edge below the cross beam, and a raised position with the edge at the level of the cross beam. The actuators have a control box (37) at human height.</p> |
