The frame has a support construction (14) including a central support part (1) at an upper rod end. Support bars (4a, 4b) run downwards between ends of a center bar that forms a hypotenuse of a support triangle and a support position (2) at a lower rod end (13a). Other support bars (3a, 3b) extend between front and/or rear sides of the support part and the support position at the lower rod end. The bar (3b) forms a support for a center rear-sided area of panel holders (8-10). The support bars (4a, 4b) are provided for supporting the panel holders. |
