Moreover, a boundary of thearc front wall 113 and thetop wall 111 and boundaries of the twosidewalls 114 and thetop wall 111 are located in a same plane. Namely, a front half part of thebottom wall 112 of themain body 110 has a shape similar to a partial bowl shape and is curled upward. Based on such configuration and the design of thearc front wall 113, a water contact area of theswing waterski 100 is decreased to decrease a water resistance, so that a moving speed of theswing waterski 100 is increased. - In the present embodiment, regarding a rear half part of the
bottom wall 112 of themain body 110, only a left side and a right side thereof are curled upward, such that the boundary of theback wall 115 and thetop wall 111 presents a arc shape similar to a symbol of smile, such that a location on theback wall 115 and farther away from one of the two side sidewalls 114 (i.e. a location on theback wall 115 more approaches to a center point) is farther away from the same plane where the boundaries of the two sidewalls and the top wall are located (i.e. the highest plane where thetop wall 111 is located). Certainly, in other embodiments, the rear half part of thebottom wall 112 of themain body 110 can also present a shape similar to the partial bowl shape and is also curled upward, which is not limited by the invention. - In the present embodiment, the
top wall 111 of themain body 110 presents a concave arc shape, and a contour of thetop wall 111 matches the contour of thebottom wall 112. Namely, a front half part of thetop wall 111 of themain body 110 also presents a shape similar to the partial bowl shape (a front end and a left and right side thereof are curled upward), and a left side and a right side of a real half part of thetop wall 111 of themain body 110 are also curled upward. Certainly, the above example is only one of the contour patterns of thetop wall 111, the concave arc shape of thetop wall 111 facilitates the user to stand or sit on thetop wall 111, though the invention is not limited thereto. In other embodiments that are not illustrated, the contour of thetop wall 111 is not matched to the contour of thebottom wall 112, for example, thetop wall 111 can be a plane, or even a convex surface protruding upward. - The
fins 120 are mounted on themain body 110 and adapted to swing. In detail, theswing waterski 100 further includes at least onefixing rack 130 fixed on thebottom wall 112 of themain body 110, and thefins 120 are fixed to themain body 110 through thefixing racks 130. In the present embodiment, the number of thefins 120 is two, and the number of the fixing racks corresponding to thefins 120 is also two. The twofixing racks 130 are respectively disposed on thebottom wall 112 of themain body 110 at positions symmetric to the center axis A. - Each of the
fixing racks 130 includes twofirst portions 132 protruding out of thebottom wall 112 and asecond portion 134 located and connected between the twofirst portions 132, and each of thefins 120 is disposed at thesecond portion 134 of eachfixing rack 130.

swing waterski 100 of the present embodiment has a special structure, it can be moved forward through a simple manner, so as to provide the user with an entertainment effect and exercise effect. In detail, since thebottom wall 112 of themain body 110 of theswing waterski 100 presents a convex arc shape, when the user operates theswing waterski 100 of the present embodiment, the user is only required to alternately exert forces to thetop wall 111 of themain body 110 at places close to two sides of thetop wall 111, for example, the left and right feet of the user alternately pedal thetop wall 111 of themain body 110 at places close to the two sides of thetop wall 111, or even the user kneels down or sits on thetop wall 111, and as long as the user swings his body, themain body 110 can be easily swung accordingly. Now, along with swing of themain body 110, thefins 120 flip the water, and theswing waterski 100 can easily move forward. - Moreover, when the user wants to make a turn, the user can pedal down the
top wall 111 at the side to be turned to. For example, when the user wants to make theswing waterski 100 to turn to the left, the user can pedal down the left side of thetop wall 110 through the left foot, such that a center of gravity is shifted to the left side of themain body 110, and since theswing waterski 100 is already moving forward, by shifting the center of gravity, theswing waterski 100 is turned to the left. Now, the right foot of the user can slightly step on the right side of thetop wall 111 to keep an overall balance. Through the aforementioned swing method, the user can easily operate theswing waterski 100 to move on the water without moving the same through a swimming manner, or by exerting a force thereon, or by using a peddle. - Moreover, as shown in

Thedrawstrings 116 are used for providing a supporting force between thetop wall 111 and thebottom wall 112. Thedrawstrings 116 divide the internal of themain body 110 into a plurality of cavities C connected to each other, and the cavities C can provide theswing waterski 100 enough buoyant force. - In the present embodiment, an external portion of the main body 110 (i.e. the
top wall 111, thebottom wall 112, thearc front wall 113, the twosidewalls 114 and the back wall 115) adopts high strength net clamping cloth with high hardness, and a material thereof is PVC, and thedrawstrings 116 in internal of themain body 110 adopts a high strength cloth, and a material thereof can be polyester. The material of thedrawstrings 116 is softer and lighter compared with the material of the external portion of themain body 110. Therefore, when theswing waterski 100 is not used, thedrawstrings 116 is easy to be bended, and the external portion of themain body 110 can also be bended to compress the wholemain body 110 into a smaller volume, so as to reduce a storage space and facilitate carry. - When the
swing waterski 100 is to be used, themain body 110 is inflated. Since the high strength net clamping cloth adopted by the external portion of themain body 110 can bear a pressure of 8 PSI (pounds per square inch) to 10 PSI, in a general condition, themain body 110 can achieve enough hardness as long as an internal pressure of themain body 110 is between 4 PSI and 5 P PSI, so as to facilitate user's usage. - Certainly, in other embodiments, the
main body 110 is not an inflatable part, but is a single kickboard, and the spirit of the invention is met as long as themain body 110 thereof has the aforementioned shape design, and along with swing of the user, theswing waterski 100 can move forward. - Referring back to
FIG. 1 , in order to facilitate the user stably standing on thetop wall 111 of themain body 110, theswing waterski 100 further includes at least oneantiskid sheet 140 disposed on the top 111 wall of themain body 110. In the present embodiment, theswing waterski 100 has twoantiskid sheets 140, which are respectively located at the left side and the right side of thetop wall 111 for the user's left and right feet to stand on. However, in other embodiments, a largeantiskid sheet 140 can be adhered to thetop wall 111 of themain body 110, and the number, location and type of theantiskid sheet 140 are not limited thereto. - Moreover, to ensure the
swing waterski 100 to stably move forward, in the present embodiment, as shown inFIG. 3 , theswing waterski 100 further includes arudder plate 150 disposed on thebottom wall 112 along a direction parallel to the central axis A of themain body 110, so as to achieve an orientation function. - In summary, in the swing waterski, the bottom wall of the main body presents a convex arc shape, and the fins are disposed on the main body and adapted to swing, such that when forces are alternately exerted to the top wall of the main body at places close to two sides of the top wall, the main body is swung to the left and right, an the fins are accordingly swung to push the swing waterski to move forward. Moreover, in the swing waterski of the invention, the boundary of the arc front wall and the top wall and the boundaries of the two sidewalls and the top wall are located in a same plane, namely, a front half part of the bottom wall of the main body has a shape similar to a partial bowl shape and is curled upward. Based on such configuration and the design of the arc front wall, a water resistance is decreased, and a moving speed of the swing waterski is increased. Moreover, the main body of the swing waterski of the invention can be an inflatable part, and can be compressed into a smaller volume to decrease a storage space when the swing waterski is not used. When the swing waterski is to be used, the main body is inflated, and since most of the main body adopts the PVC material with high hardness, the main body becomes rather hard after being inflated, so as to facilitate user's operation.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
