  • Publication number: 20100307283
    Abstract: An operating lever for a wind-surfing or kite board is a two-layer hollow water-drop-shaped pipe. With the water drop shape, the operating lever can be stably gripped by the user, and the undesired slippage of the operating lever can be avoided, so that the user can grip the operating lever more effortlessly. The two-layer hollow structure enhances the structure strength of the operating lever, so that the operating lever can be made of aluminum material without causing the increase of cost.
