Abstract
A self-leveling support includes a first stile (1) and a second stile (2), a first leg member (6) and a second leg member (7), each having an elongate element adapted to move longitudinally relative to one of the stiles (1, 2), a spacer (3) adapted to secure the stiles (1, 2) substantially parallel to each other, and a cross member (8) adapted to pivot about a pivot pin (9) acting in a guide (10) in the spacer (3) substantially midway between the stiles (1, 2), the cross member being connected at each end to a respective portion of the leg members, angular movement of the cross member about or with the pivot pin causing one leg member to move outwards relative to its respective stile while the other leg member moves inwards relative to its respective stile.
