STUDY FOR THE CONSTRUCTION OF AN AMPHIBIOUS BICYCLE

摘要

Body of light, strong material, Figures 1, 2. Frame of bicycle suitably shaped so as to fit on the body, Figures 1, 2. The amphibious bicycle also has three wheels, one located on the front part 2, Figure 2, and the other two 7, 8 (bicycle wheels/paddles) at the rear, Figure 1. All the wheels/paddles have wing nuts so they can easily be detached or fixed to the shaft 6, Figure 1. Motion is transmitted from the pedals 4, through a belt or chain 5, to the rear wheels, figure 1. The front wheel can be replaced by a navigation vane 3, Figure 2. The vane is removed during movement on dry land. The body, Figure 1, has, at its middle, two folding balloons 2, 3, Figure 1 which are linked to the body and are able to open and close. These fins are used only at sea to improve the stability of the amphibious bicycle and during motion on dry land they are placed in special containers 14, 15 on the body 4, 5, Figure 1. It is also equipped with a gear system for better performance in motion as well as a braking system.
