Abstract

A water ski system which includes 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 device propels a 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.

Claims

exact text as granted — not AI-modified
What is claimed is new and desired to be protected by Letters Patent is set forth in the appended claims: 
     
         1 . A 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;   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;   a foot mount and a toe of a boot pivotally affixed to the top surface of at least one said buoyant ski, the boot configured to receive a foot of a user and rotate on a pivoting member able to manipulate the pivoting paddle with foot movement; and   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 configured to further propel the user across water when manipulated.   
     
     
         2 . The water ski system of  claim 1 , wherein the boot is removable from the pivoting member. 
     
     
         3 . The water ski system of  claim 1 , wherein a heel of the boot is non-affixed to the buoyant ski allowing for the user to raise one's heels with each step approximate a normal walking motion. 
     
     
         4 . The water ski system of  claim 1 , wherein the pivoting member is configured to release when certain force-limits are exceeded to avoid injury. 
     
     
         5 . The water ski system of  claim 1 , wherein the buoyant ski further comprises a fixed-fin located on the bottom surface of the buoyant ski at the back. 
     
     
         6 . The water ski system of  claim 1 , wherein the ski pole provides resistance based on the force that is required to submerge a buoyant object. 
     
     
         7 . The water ski system of  claim 1 , wherein the ski pole is buoyant and provides a floatation device. 
     
     
         8 . The water ski system of  claim 1 , wherein the boot comprises a flexible material for form fitting the foot of the user. 
     
     
         9 . The water ski system of  claim 8 , wherein the flexible material selected from a group including silicone, rubber, plastic configured to conform to the foot of the user. 
     
     
         10 . The water ski system of  claim 1 , wherein the buoyant ski is configured to provide floatation means having sufficient buoyancy and stability to allow the user to maintain balance on a surface of the water. 
     
     
         11 . The water ski system of  claim 1 , wherein the pivoting paddle is coupled to the bottom surface of the buoyant ski on a paddle hinge that allows for backward movement to allow low friction moving forward, but remains effectively vertical when moving backwards. 
     
     
         12 . The water ski system of  claim 11 , wherein the paddle hinge is located inside the buoyant ski to reduce friction. 
     
     
         13 . The water ski system of  claim 1 , wherein the front of the buoyant ski comprises a semi-curved profile. 
     
     
         14 . The water ski system of  claim 1 , wherein the buoyant ski comprises more than one pivoting paddle. 
     
     
         15 . The water ski system of  claim 1 , wherein the buoyant ski comprises exactly one pivoting paddle. 
     
     
         16 . The water ski system of  claim 1 , wherein the heel of the boot is affixed to the buoyant ski via a heel-locking member. 
     
     
         17 . A 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;   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;   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 configured to further propel the user across water when manipulated;   a foot mount and a toe of a boot pivotally affixed to the top surface of at least one said buoyant ski, the boot configured to receive a foot of a user and rotate on a pivoting member able to manipulate the pivoting paddle with foot movement;   wherein the buoyant ski further comprises a fixed-fin located on the bottom surface of the buoyant ski at the back;   wherein the front of the buoyant ski comprises a semi-curved profile;   wherein the buoyant ski is configured to provide floatation means having sufficient buoyancy and stability to allow the user to maintain balance on a surface of the water;   wherein the pivoting paddle is coupled to the bottom surface of the buoyant ski on a paddle hinge that allows for backward movement to allow low friction moving forward, but remains effectively vertical when moving backwards;   wherein the paddle hinge is located inside the buoyant ski to reduce friction;   wherein the boot comprises a flexible material for form fitting the foot of the user;   wherein a heel of the boot is non-affixed to the buoyant ski allowing for the user to raise one's heels with each step approximate a normal walking motion;   wherein the pivoting member is configured to release when certain force-limits are exceeded to avoid injury;   wherein the ski pole provides resistance based on force that is required to submerge a buoyant object; and   wherein the ski pole is buoyant and provides a floatation device.   
     
     
         18 . The water ski system of  claim 17 , further comprising a pair of buoyant skis, and a pair of ski poles; and
 wherein the water ski system is arranged as a kit.
