Abstract: A self-erecting tent can be erected in various sizes and shapes and is characterized by the fact that the tent can be changed. It can be mounted on a transportable or rolling and supportable platform, which can be converted from a transport position into an erection position. The tent consists of a telescopic support mast and a plurality of telescopic arms, the folded roof fabric being connected to the endmost extended element of each arm in order to provide tension and support when it is extended and foldability when it is retracted.
