1. Field of the Invention
The present invention relates generally to marine vessels and, more specifically, to a nautical propulsion device comprising a plurality of cooperating paddles driven by levers in a sweeping motion while cooperating with a peddle gear and electric motor in order to produce a reciprocating back and forth paddle motion capable of driving a vessel through water densely populated with obstructive matter such as grass, Lilly pads, logs and other debris with ease. Comprising the paddles main assembly are two pivotally mounted paddles having lever arms attached to the non submerged distal ends of sad paddles so that when a peddle gear is driven a plurality of linkages cooperate to produce the opposed back and forth motion of the operating paddles. Additionally the pedal gear of the present invention allows for the paddles to be lifted while being brought towards the vessel wherethen said paddle is brought downward and away from the vessel to push the device forward. Finally a speed throttle is mounted to the device to control the speed at which the paddles reciprocate and control the directions that force is applied in to the back of a vessel.
2. Description of the Prior Art
While there are other nautical paddle based propulsion systems that may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
A primary object of the present invention is to provide a propulsion method for a vessel whereby it can easily transverse shallow water with a high concentration of grass, Lilly pads, logs and debris with ease utilizing a pair of pivotally and horizontally, transgressing paddles.
Another object of the present invention is to provide a propulsion method for a vessel whereby paddles are arranged as such to submerge a paddle while progressing a paddle away from the vessel while alternately lifting the paddle out of the water on its return path back toward the vessel.
Yet another object of the present invention is to provide a propulsion method for a vessel whereby paddles are arranged to create an even complimentary back and forth motion in order to propel a watercraft.
Still yet another object of the present invention is to provide a propulsion method for a vessel whereby paddles are arranged and electrically driven to propel a watercraft
Another object of the present invention is to provide a propulsion method for a vessel whereby paddles are arranged onto a platform and unit that is independently constructed to be mounted to a vessel like an outboard motor
Yet another object of the present invention is to provide a propulsion method for a vessel whereby a throttle control is provided to control the speed the paddles move at and to control the direction of said displacement is directed.
Still yet another object of the present invention is to provide a propulsion method for a vessel whereby a plurality paddles can ganged or expended to deli a propulsion method for a vessel whereby paddles are arranged ver more aqueous displacement per stroke.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the shortcomings of the prior art by providing a propulsion method for a vessel whereby it can easily transverse shallow water with a high concentration of grass, Lilly pads, logs and debris with ease utilizing a pair of pivotally and horizontally, transgressing paddles utilizing a system of paddles that are arranged as such to submerge one such pivotally mounted paddle while progressing a paddle away from the vessel while alternately lifting a second partner paddle out of the water on its return path back toward the vessel. Additionally the present invention provides for a means of controlling the speed the device operates, the direction motive force is directed and means for mounting the device to a vessel's stern. Finally the present invention is electrically driven by an electric motor coupled to associated pedal like gearing.
The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawing, which forms a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. In the accompanying drawing, like reference characters designate the same or similar parts throughout the several views.
The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is best defined by the appended claims.
In order that the invention may be more fully understood, it will now be described, by way of example, with reference to the accompanying drawing in which:
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the Figures illustrate the method of constructing a catalog of the resources accessible through a network of the present invention. With regard to the reference numerals used, the following numbering is used throughout the various drawing figures.
The present invention relates generally to marine vessels and, more specifically, to a nautical propulsion device comprising a plurality of cooperating paddles driven by levers in a sweeping motion while cooperating with a peddle gear and electric motor in order to produce a reciprocating back and forth paddle motion capable of driving a vessel through water densely populated with obstructive matter such as grass, Lilly pads, logs and other debris with ease. Comprising the paddles main assembly are two pivotally mounted paddles having lever arms attached to the non submerged distal ends of sad paddles so that when a peddle gear is driven a plurality of linkages cooperate to produce the opposed back and forth motion of the operating paddles. Additionally the pedal gear of the present invention allows for the paddles to be lifted while being brought towards the vessel wherethen said paddle is brought downward and away from the vessel to push the device forward. Finally a speed throttle is mounted to the device to control the speed at which the paddles reciprocate and control the directions that force is applied in to the back of a vessel.
The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims.
In operation, motor 42 in electrical communication 44, 46 with power supply 48, and throttle 68 drive gears 50,52 connected by drive belt 54 to sprocket 56 supported on beam 30 by support 32 whereby gear 34 with arms 36 extending therefrom engage by fastener 38 paddles 40 having blade end 66 with the distal end pivotally fastened to linkage 62 at pivot 60, 64 thereby driving blade end 66 through a water stroke while the other is raised out of the water and returned to a starting water stroke position.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of devices differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
