    • A surfboard has ribbed or corrugated side rails for improved strength without an increase in weight. In a first embodiment, the board comprises a rigid, buoyant foam core, over which a rigid shell is formed, the shell having side rails with at least one external longitudinal rib. In a second embodiment, the board comprises an injection-molded plastic shell, into which a buoyant foam material is injected. The shell is formed with at least one internal longitudinal rib along each side rail. A portion of the top surface of the surfboard is covered with a layer of unbroken loop nylon material overlying a layer of closed cell foam material to form a resilient, non-abrasive, slip-resistant, water-repellent mat. A foot piece having a sole portion of unbroken loop nylon material is removably attachable to the mat by a double-sided patch of fibrous hook material.
    • 冲浪板具有带肋或波纹的侧轨,用于提高强度而不增加重量。 在第一实施例中,板包括刚性的浮力泡沫芯,在其上形成刚性壳,壳具有具有至少一个外部纵向肋的侧轨。 在第二实施例中,板包括注射成型的塑料外壳,其中注入浮力泡沫材料。 壳体沿着每个侧轨形成有至少一个内部纵向肋条。 冲浪板的上表面的一部分被一层不间断的环状尼龙材料覆盖,覆盖一层闭孔泡沫材料层,以形成一种弹性的,非研磨性的,防滑的防水垫。 具有不间断环尼龙材料的唯一部分的脚件通过纤维钩材料的双面贴片可拆卸地附接到垫子上。

    • A method and apparatus for reducing friction in a cam buckle for tightening a strap. The cam buckle includes a frame, a brake member, a roller member, a biasing element and a webbed strap. The brake member includes a serrated surface and is rotatably coupled to the frame and pivotal about a first axis. The roller member is rotatably coupled to the frame about a second axis, wherein the first axis and the second axis are substantially parallel to each other. The biasing element is operable to bias the serrated surface of the brake member toward the roller member. The webbed strap is formed from a polymeric material and is operable to be biased between the serrated surface and the roller member so that the brake member biases the webbed strap against the roller member. With this arrangement, when the webbed strap is placed in tension, such tension is maintained by preventing movement of the webbed strap in one direction and allowing movement in a second direction to increase the tension. The roller member is operable to rotate with movement of the webbed strap in the second direction to increase the tension in the webbed strap.
    • 一种用于减小用于紧固带的凸轮扣中的摩擦的方法和装置。 凸轮扣包括框架,制动构件,滚动构件,偏压元件和带状带。 制动构件包括锯齿状表面并且可旋转地联接到框架并围绕第一轴线枢转。 辊构件围绕第二轴线可旋转地联接到框架,其中第一轴线和第二轴线基本上彼此平行。 偏置元件可操作以将制动构件的锯齿状表面朝向辊构件偏压。 网状带由聚合物材料形成,并且可操作以在锯齿形表面和辊构件之间被偏压,使得制动构件将带状带偏压在辊构件上。 通过这种布置,当将带状带放置在紧张状态时,通过防止带状带在一个方向上的移动并允许沿第二方向移动以增加张力来保持这种张力。 辊构件可操作以随着带状带在第二方向的移动而旋转,以增加带状带中的张力。
