<p>The proposed aquatic propulsion means use oscillating blades (1, 2, 3, 4, 5) with independent vertical shafts (9) that are parallel to one another and that are attached at the upper end thereof to a single flat horizontal oar (11), said blades or fins being of different length depending on the distance between the attachment point of the axis of oscillation thereof and the shaft (12a) about which the oar rotates. Propulsion is generated when the user applies muscle force, traction or thrust, to either of the two handles (16) provided at each end of the handlebars (14), or in opposite directions on both simultaneously, said movement being transmitted to the rotary shaft (12a) and then to the profile (11) on which the fins are arranged, forcing them to move transversely and alternately in both directions, thereby moving the water and propelling the floating vehicle, object or swimmer in the desired direction, which corresponds to the midpoint of the oscillating stroke of the oar (11).</p> |
