Description

CROSS REFERENCE TO RELATED APPLICATION

The present application is related to and claims priority to U.S. Provisional Patent Application No. 62/445,144 filed Jan. 11, 2017, which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

1. Field of the Invention

The present invention relates generally to the field of water skis and more specifically relates to a water ski system.

2. Description of Related Art

Water skiing is a surface water sport in which an individual is pulled behind a boat or a cable ski installation over a body of water, skimming the surface on two skis or one ski. Water skiers can use two skis or one ski. Generally the heavier the person, the bigger the skis will be. Length will also vary based on the type of water skiing being performed. Many individuals enjoy the art of surfing, but conventional surfing requires the user to lay flat on the surfboard when moving towards or away from the surf. This motion excludes the use of the legs, which are the most powerful muscle and requires that all the effort fall to the arms. This can result in the individual becoming prematurely fatigued and moving slowly in the water. A suitable solution is desired.
U.S. Pat. No. 7,607,959 to James Warren Demint relates to a personal water craft to enable a user to walk on water. The described personal water craft to enable a user to walk on water includes a water craft which allows a user to travel across a surface of water utilizing a natural walking motion, which employs arms and legs for propulsion similar to cross-country snow skiing. The water craft includes a pair of skis adapted to fit on the user's feet. The skis can be coupled together by semi-elastic tethers. Each ski can include a foot well for receiving the user's foot. The foot well is designed to simulate the natural walking motion of the user. The user can propel the water craft using tail paddles and ski poles. The tail paddles are coupled to the rear of the skis. The tail paddles are configured to float on the water and to rotate about a transverse axis of the skis. The tail paddles are shaped to grip or “dig in” the water in response to the user moving the skis in a direction opposite the direction of motion of the water craft. The tail paddles provide resistance to propel the water craft when the ski is moved backward and slide along the water when the skis move forward. The ski poles include a paddle shaped to grip or “dig in” in response to the user pushing backwards on the ski poles. The paddle provides resistance to the backwards motion to propel the water craft forward. When the user pulls the ski poles forward, the paddles surface and slide across the water as the water craft moves forward.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known water ski art, the present disclosure provides a novel water ski system. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a set of skis to enable a user to move on a surface of water in a similar motion as with a cross country ski. The device provides a cross ocean ski that allows for buoyancy, with a fixed fin for stabilization and one or more paddles that rotate on a hinge.
A water ski system is disclosed herein. The water ski system comprising two essentially identical assemblies each assembly including a buoyant ski having a top surface, a bottom surface, a front, and a back configured to float on water. Each buoyant ski includes a pivoting paddle located on the bottom surface of the buoyant ski configured to deploy in a backwards motion and retract in a forward motion against a force of water in a motion similar to cross-country skiing. The assemblies also include a ski pole having a distal end and a proximal end; the distal end having a cupping member and the proximal end having a user-handle. The cupping member may be configured to further propel the user across water when manipulated. Each buoyant ski has a foot mount and a toe of a boot pivotally affixed to the top surface of the buoyant ski. The boot is configured to receive a foot of a user and rotate on a pivoting member able to manipulate the pivoting paddle with foot movement.

DETAILED DESCRIPTION

As discussed above, embodiments of the present disclosure relate to water skis and more particularly to a water ski system as used to improve the water ski system.
Generally, the present invention utilizes a set of boards to enable a user to move on the surface of water in a similar motion as with a cross country ski. It provides a cross ocean ski that allows for buoyancy, with a fixed fin for stabilization and one or more paddles that rotate on a hinge. This allows users to push water backwards when moving their legs backwards in order to move forward in the water using their legs. It enables the user to move both legs freely to move easily in any direction on the water.
The present invention affords users the ability to approach waves and catch them in a surf-like manner, but while using movements similar to skiing, as opposed to conventional surfing. Water ski system offers a set of cross-country like skis designed to function on water. The skis are comprised of a rubber boot with a hinge in front that is affixed to the top of a highly floating board. Below the board, a fin is fixed to the surface of the board to provide stability. The fin may be made molded to the board or affixed using glue, screws, or other means. The bottom paddle or paddles may be fixed below the board on a hinge that allows for backward movement to allow low friction moving forward, but remains vertical when moving backwards.
To avoid friction, the paddle hinge may be inside the board, in a groove made for this purpose. The boots are designed to fit snugly and are available in various sizes. In use, the skis are designed to float enough to remain above water with a person on top. In the application of surfing strong waves, the hinge may be designed to give away for safety reasons. The binding of the present invention releases the boot when the binding is over stressed by forces acting in any direction.
