<p>The support comprises two separate and identical stands (3) which can fold up for storage purposes. Each stand has two legs (6,7) joined together (8) at the top and held by a folding tie bar (9,10) at the bottom. A triangular frame is formed, the lower edge (23) of the sign (1) resting on a grooved block (4) at the apex of each stand. The upper edge of the sign is gripped by rods (5) extending through locking slides (20,21) on each stand. Hooks (22) on the end of each rod pass over the top edges of the panel to hold it down.</p> |
