The present invention relates to the methods to solve the problem of portability of the prior man-powered water ski and also to solve the problem of the lateral unbalance of said ski hull.
BACKGROUND OF THE INVENTIONThe present invention is a new and improved model of the prior one that I obtained U.S. patent in the name of Water Ski with Propulsion Guide Poles and also obtained Korea Patent in the same contents of the invention. My prior invention comprised a single hull, a rudder at the stern bottom of the ski hull, and a pair of ski poles having propulsion medium on end part of each ski pole shaft. With only those said elements, a skier was prone to have hard time to balance himself laterally on the ski hull when riding the water ski. The long length of the ski hull caused the inconvenience of portability, which was not possible to put the ski hull in the car but also hard to carry it here and there. Due to those two defects of the lateral unbalance of the ski hull and its inconvenience of portability, I herein provide the present invention to solve said defects.
SUMMARY OF THE INVENTION Problems to be Solved by the InventionThe object of the present invention is to provide the methods to solve two defects of my prior invention which had the inconvenient portability and the lateral unbalance of a skier on the deck of the ski hull when in use.
Means for Solving the ProblemTo eliminate the said defect of lateral unbalance, the ski hull comprises a lateral balancing board, a lateral balancing wing at each side of the stern section, and a set of foot skid pad and instep Velcro belt of a skier each side on the deck of the mid section of a ski hull. And also to eliminate the defect of inconvenient portability of the ski hull and ski poles, the ski hull forms 3 sections foldable, a lateral balancing board removable, each auxiliary lateral balancing wing attachable to and extendable outward each side of stern section of the ski hull, and each ski pole shaft separable into three parts: two sections of the ski pole shaft and a propulsion medium like a plate.
The present invention comprises the bow section foldable on top of the mid section of ski hull by pivoting the connecting hinge on each side between the bow section and the mid section, the stern section foldable on the bottom of the mid section by pivoting the connecting hinge on each side between the stern section and the mid section, push-in and pull-out type of the lateral balancing board, a rudder push-able in its housing and pull-able out of it, a wing attachable to each side of the stern section, a set of the dividable ski poles at its each mid-point, and a set of the propulsion plates separable at endmost part of each pole. All of those said members of the ski embodiment can be compacted into a portable ski case. This way maximizes the convenient portability of a whole set of ski. The lateral balancing board stretched down at the mid section, the auxiliary lateral balancing wing extended outwardly each side of the stern section, and a set of foot skid pad and instep Velcro belt of a skier each side of the mid section deck maximizes the lateral balance of a ski hull.
Effect of the InventionThe present invention provides two maxima effects which are the most possible portability and the most possible lateral balance of a ski hull. The maximum effect of the portability is provided by each ski pole easily disarticulated, a lateral balancing board separated from the ski hull, a rudder pushed into its housing, each wing attached to each side of the hull, and a 3 layer folded ski hull, and those said elements packed into the portable ski case. This way makes a complete set of a water ski package, which can be carried anywhere by car, bicycle, motorcycle, and airplane. The maximum lateral balance effect of a skier on the deck of the hull is provided by stretching down the lateral balancing board, extending outwardly the auxiliary lateral balancing wing at each side of the hull, and standing on each foot skid pad at each side of the mid section deck and fastening skier's incept with Velcro belt when propelling the ski.
The present invention is described as follows by attaching the figures:
The auxiliary lateral balancing wings 14, 15 are attached to the recess of each side of the stern section when riding on the still or relatively low waved water surface and extended outwardly each side of the stern section 13 when riding in the relatively high wave. When extending outwardly the auxiliary lateral wings 14, 15 each side of the stern section 13, the right wing is fixed in parallel with the ski hull direction at endmost bar 18 by a rigid bolt 20 or other proper device and the wing supporting bar 18 is fixed at the starting point of the bar on the right end spot of the stern section 13 by a device having a rotating and fixing property: the left wing is fixed in the same way. The material for the ski hull and both wings is the same as used in the manufacture of the surfboards and as a material for the wing supporting bars is acceptable any stainless steel material.
Two handles 35,36 fixed in each side of mid section of the ski hull are the convenient handholds for a skier to get back on the deck of the hull when the skier loses his or her balance on the deck and falls down into water out of the deck, and also are helpful for a skier to carry or move the ski hull here and there along the beach. The lateral balancing board is to push down through the top opening of the big slot 42—which has a passing-through channel from the deck of the mid section 12 to the bottom of the section—and pull down from its bottom opening of the mid section. A hole on each side of the mid section 12 is for thrusting and resting the endmost part of the ski pole in it when a skier is resting in the water or when leaving the ski hull on the beach.
When folding the bow section over the mid section of the hull, a skier first of all pulls off the lateral balancing board 22 from the mid deck 12 and releases a hook 44 (other side 43) off from the a hook assembly at the bottom of both sections and when folding the stern section bottom over the mid section bottom, the skier first pushes the rudder in its housing and pulls off a top Velcro cloth—hooks part—from the bottom part of the Velcro cloth on the both decks. In this way the whole ski hull is transformed into 3 layer folded hull.
A rotating and fixing assembly 16 (other side 17) of a wing supporting bar 18 (other side 19) is fixed on the end area of each side of the stern section and a endmost tip of the wing supporting bar 19 (other side 18) is fixed on the rotating and fixing assembly, and each auxiliary wing 14 (other side 15) is fixed beneath the wing supporting bars 18,19 by the attaching devices 20,21.
Claims
1. A ski hull dividable into 3 sections and 3 layer foldable, a ski pole dividable into 2 parts at the mid spot of the shaft, a propulsion medium like a plate separable from the shaft at its end part, two auxiliary lateral balancing wings adjustable and attachable at each side recess of the stern section of the ski hull, a rudder at the bottom of the stern section push-able into its housing, a lateral balancing board separable from the mid section, and a portable ski case packed with all the said elements of the ski embodiment provides the feature of the maximum convenient portability effect. The lateral balancing board fixed vertically at the bottom of the mid section of the ski hull increases the lateral balance of the ski hull, the auxiliary lateral balancing wings extended outwardly each side of the stern section increases more the lateral balance of the ski hull, and both foot skid pads and both instep Velcro belts located each side of the mid section deck of the ski hull increases most the lateral balance of the ski hull. Those said 3 methods of the lateral balance provide the maximum lateral balance effect of a ski hull.
2. In the claim 1, the man-powered water ski with the feature increasing the lateral balance of the ski hull by the lateral balancing board.
3. In the claim 1, the man-powered water ski with the feature increasing more the lateral balance of the ski hull by the extended auxiliary lateral balancing wings.
4. In the claim 1, the man-powered water ski with the feature increasing most the lateral balance of the ski hull by the foot skid pads and the instep Velcro belts.
5. In the claim 1, the man-powered water ski with the feature increasing the speed of the ski by reducing water friction of the lateral balancing board due to inclining backward of the said board as a skier thrusts the ski forward.
