Abstract
Abstract A device for enabling a pedestrian to walk on water including a pair of floats supporting a frame which rigidly connects the floats one to the other in a parallel side-by-side spaced apart relationship. Left and right pendulum arms depend from the frame. At least one paddle is pivotally attached to each pendulum arm to provide propulsion to the floats as the pedestrian actuates the pendulum arms and the paddles by moving his legs in a manner similar to walking. A keel depends from the frame and extends into the water between the paddles to partially define independent channels or slips for the left and right paddles for increasing the propulsion developed by each step taken by the pedestrian, i.e., the slips further being defined by portions of the inboard sides of the floats. Forward and reverse stops are included which are attached to the paddles, enabling the pedestrian to selectively develop forward or reverse propulsion to change the direction of travel of the device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
193 words
In a device for enabling a pedestrian to walk on water having frame means, float means providing buoyancy for supporting the device on the water, pendulum means pivotally attached to said frame means, and paddle means pivotally attached to said pendulum means for providing propulsion to said floats as the pedestrian actuates said pendulum means and said paddle means by moving his legs in a manner similar to walking, forward and reverse stop means for limiting the pivoting rotation of said paddle means, said stop means comprising first tab means fixedly attached to said paddle means adjacent the uppermost portion thereof and being substantially perpendicularly disposed with said paddle means for engagement thereof with the ball portions of the pedestrian''s feet to limit the pivotal rotation of said paddle means in one direction for forward propulsion, and second tab means fixedly attached to said paddle means adjacent the uppermost portion thereof and being substantially diametrically disposed from said first tab means and displaced laterally therefrom for selective engagement thereof with the heel portions of the pedestrian''s feet to limit the pivotal rotation of said paddle means in an opposite direction for reverse propulsion.
Claim 2
Dependent Claim
193 words
In a device for enabling a pedestrian to walk on water having frame means, float means providing buoyancy for supporting the device on the water, pendulum means pivotally attached to said frame means, and paddle means pivotally attached to said pendulum means for providing propulsion to said floats as the pedestrian actuates said pendulum means and said paddle means by moving his legs in a manner similar to walking, forward and reverse stop means for limiting the pivoting rotation of said paddle means, said stop means comprising first tab means fixedly attached to said paddle means adjacent the uppermost portion thereof and being substantially perpendicularly disposed with said paddle means for engagement thereof with the ball portions of the pedestrian''s feet to limit the pivotal rotation of said paddle means in one direction for forward propulsion, and second tab means fixedly attached to said paddle means adjacent the uppermost portion thereof and being substantially diametrically disposed from said first tab means and displaced laterally therefrom for selective engagement thereof with the heel portions of the pedestrian''s feet to limit the pivotal rotation of said paddle means in an opposite direction for reverse propulsion.
Claim 3
Independent Claim
238 words
A device for enabling a pedestrian to walk on water, said device comprising frame means, a pair of floats for providing buoyancy to support said frame means and the pedestrian upon a body of water, said frame means including transverse beam means rigidly interconnecting said floats in a parallel side-by-side spaced apart relationship, fore and aft extending beam means disposed substantially midway between said floats, and upright support means for supporting said fore and aft extending beam means a predetermined distance above said floats; said upright support means including a plurality of tubular members each having the mid-portion thereof vertically disposed, the lower portion thereof being horizontally disposed and directed outwardly towards said floats and being supported by said transverse beam means, and the upper portion thereof being horizontally disposed and directed inwardly from said mid-portion substantially perpendicular to said lower portion and having said fore and aft extending beam means attached thereto; right and left pendulum arm means depending from said fore and aft extending beam means, and partially submerged paddle means pivotally attached to the lower portion of each of said pendulum arm means for providing propulsion to said floats, said paddle means alternately being caused to provide a power stroke and a return stroke respectively by pivotal movement about the lower portions of said pendulum arm means as the pedestrian actuates said pendulum arm means by moving his legs in a manner similar to walking
Claim 4
Independent Claim
238 words
A device for enabling a pedestrian to walk on water, said device comprising frame means, a pair of floats for providing buoyancy to support said frame means and the pedestrian upon a body of water, said frame means including transverse beam means rigidly interconnecting said floats in a parallel side-by-side spaced apart relationship, fore and aft extending beam means disposed substantially midway between said floats, and upright support means for supporting said fore and aft extending beam means a predetermined distance above said floats; said upright support means including a plurality of tubular members each having the mid-portion thereof vertically disposed, the lower portion thereof being horizontally disposed and directed outwardly towards said floats and being supported by said transverse beam means, and the upper portion thereof being horizontally disposed and directed inwardly from said mid-portion substantially perpendicular to said lower portion and having said fore and aft extending beam means attached thereto; right and left pendulum arm means depending from said fore and aft extending beam means, and partially submerged paddle means pivotally attached to the lower portion of each of said pendulum arm means for providing propulsion to said floats, said paddle means alternately being caused to provide a power stroke and a return stroke respectively by pivotal movement about the lower portions of said pendulum arm means as the pedestrian actuates said pendulum arm means by moving his legs in a manner similar to walking
Claim 5
Dependent Claim
68 words
The device of claim 2 in which is included forward and reverse stop means attached to said left and right paddle means for engagement thereof by the feet of the pedestrian enabling him to selectively change the direction of the propulsion from a forward direction to a reverse direction and from the reverse to the forward direction as he moves his legs in the manner similar to walking.
