A rod assembly (2) has two flexible single intersecting rods (4), which, when in a position of use, have tips at their ends (5) to connect into links at the ends (8) of two belt straps (9) intersecting on the ground. The rod assembly and the single rods are arched like a cupola roof. A cross strut (19) to support a cloth (3) is supported in the intersecting area of the single rods. |
