ABSTRACT:
The advertising support consists of a stowage space (3) with an opening top and an inflatable advertising support (11) stowed inside it which, when the top of the stowage space (3) is opened, can be inflated upwards from it. In the stowage space (3) there is a scissors structure (7,17) which can be erected by a motor and forms a stable-sided parallelogram which is free-standing and, in the expanded position, extends along the internal height of the inflated advertising support (11). It ensures that, when the scissors structure (7,17) is retracted and the advertising support (11) is deflated at the same time, said advertising support (11) is substantially folded down onto its original base area and prevented from tipping sideways by the lateral stability of the scissors structure.
