<p>The invention relates to an apparatus and a method for collapsing a means of transport from running position into storage position or vice versa. Collapsing is preferably performed using an electric motor or by hand, the mutual movements of the front part frame (1), the rear part frame (3) and the reversible rod (7) being preferably synchronised using cogged belt pulleys (5,6) and the reversible rod (7). Owing to synchronisation, the centre of gravity of the transport means is stable and remains within an area defined by the wheels (2,4) during the entire collapsing operation, so that collapsing takes place completely without any external support.</p> |
