<p>Man-propulsed recreational amphibious vehicle comprised of two octogonal rings (3) arranged vertically, and two additional semi-spherical air-inflated floats (1). The octogonal rings (3) and the semispherical floats (1) are linked by means of a tubular structure (2, 6), the semispherical floats (1) being arranged at the sides of the octogonal rings (3). The pilot stands inside the rings (3), and has straps so that the pilot can grip the structure. In said rings (3), there is provided a system of blades (4) hinged by shafts (5) and intended to propulse the craft; the pilot generates a force required to displace the craft by walking inside the vehicle.</p> |
