Abstract
PURPOSE: To elevate an efficiency for a paddle and increase speed for a boat of a float type by installing a means paddling a couple of paddles port and starboard, being alternatively moved in a horizontal and parallel direction by means of an alternative contraction and extention stepping action of both legs.
CONSTITUTION: As a right leg is stepped forward a port paddle 8 is moved forward being fallen backward sustaining water resistance while a paddle erecting roller 7 in the middle is pushed by projections of both sides of the paddle, falling down forward pressing a spring 9, erecting again after it has passed projections in both sides. At the same time, a left-paddle is moved jointly, and projections of both sides are erected moving along a paddle erecting roller 7 thereby erecting whole paddles, while the roller 7 comes off from an upper portion of the paddle, thence the paddle moves aft erecting and paddling water. Next, as the left leg is stepped forward the left paddle being fallen moves forward pushing down the paddle erecting roller 7, and the right paddle erects along the paddle erecting roller 7, thereby paddles water. The boat is propelled with the aforementioned action.
