    • A ski tow arrangement for water skiing comprising an elongated handle having a pair of transverse openings and a tow line having free ends terminating in a loop extending into each of the openings. A flat T-shaped retainer is engaged by each of the loops and includes a central portion extending into the handle with laterally projecting barbs engaging opposing wall surfaces of the handle openings for resisting removal. The head portions of the T-shaped retainers abut an external rearward edge of the handle. The handle itself comprises a wooden core into which the retainer barbs are embedded, an aluminum sleeve surrounding the core and a casing of resilient friction material molded over the core. A pair of sleeves are formed integrally with the casing and project forwardly of the handle coaxially with the core openings for embracing the tow line and protecting a skier's hands from abrasion thereagainst.
    • 一种用于滑水的滑雪道装置,其包括具有一对横向开口的细长手柄和具有终止于延伸到每个开口中的环的自由端的牵引线。 平坦的T形保持器由每个环接合并且包括延伸到手柄中的中心部分,其具有与手柄开口的相对的壁表面接合以阻止移除的侧向突出的倒钩。 T形保持件的头部抵靠手柄的外部后边缘。 手柄本身包括一个木芯,保持器倒钩嵌入其中,围绕芯的铝套筒和模制在芯上的弹性摩擦材料的壳体。 一对套筒与壳体一体地形成并且与把手的芯部开口同轴地向前突出,用于包围拖绳并保护滑雪者的手免受磨损。

    • A towing system in which a moving traction means has pickup means thereon movable into engagement with one end of an elongated element, such element being capable of transmitting tension forces but being incapable of transmitting compressive forces and having a body attached to its other end. Such element is maintained taut preparatory to and during the instant of initial connection between the traction means and elongated element so as to extend tautly at a right angle with respect to direction of movement of such traction means whereby the body is accelerated smoothly and without substantial jerk from zero speed to the speed of the traction means.
    • 一种牵引系统,其中移动牵引装置具有可在其上移动的细长元件的一端的拾取装置,该元件能够传递张力,但不能传递压缩力并且具有附接到其另一端的主体。 这种元件在牵引装置和细长元件之间的初始连接的瞬间被保持紧固,并且在相对于这种牵引装置的运动方向以直角延伸的方式延伸,从而身体平滑地加速并且没有大的冲击 从零速度到牵引装置的速度。
