<p>The present invention refers to a new model of propelled scooter by the action of two pedals (1) with a closed-circuit transmission, formed by two chains (7) with stretched rubber/string, which activate two free wheels (8), achieving at the same time to turn the rear wheel in the same and one sense. The novelty about this model is based in the disposition of the two rockers foot-switches, which transfer the energy through a rock shaft (2) and two free wheels (8), transforming this movement from alternating to rotating. The rock shaft (2) transmits the energy and when one pedal goes up, the other goes down. At the end of each pedal there is a chain or a strap, which activates the two free wheels (8). The chain or strap is held by a closed-circuit self-stretched by pulleys.</p> |
