    • A fork assembly for a bicycle includes a pair of forks and a steerer tube that extend in generally opposite directions from a fork crown. The assembly includes first and second means for securing the steerer tube to the fork crown. Preferably, the steerer tube is threaded and bonded to the fork crown. The fork crown includes a pair of cavities that each slidably receives a respective fork. Preferably, each fork is formed of a carbon fiber material and has an end whose shape substantially matches a shape of a respective cavity formed in the crown. The forks and crown cavities cooperate to efficiently communicate loads between the forks and the fork crown while maintaining a lightweight and robust fork, fork crown, and steerer tube assembly.
    • 用于自行车的叉组件包括一对叉和一个从叉形凸起大致相反的方向延伸的转向管。 该组件包括用于将转向管固定到叉形表冠的第一和第二装置。 优选地,该转向管被螺纹连接到叉形牙冠上。 叉头包括一对空腔,每个空腔可滑动地容纳相应的叉。 优选地,每个叉由碳纤维材料形成,并且其端部的形状基本上与在冠部中形成的相应空腔的形状相匹配。 叉和冠腔配合以有效地在货叉和叉顶之间传递载荷,同时保持轻便且坚固的叉,叉冠和转向管组件。

    • A mechanically joined steering assembly for supporting the wheel of a wheeled vehicle for steering movement relative to the frame of the vehicle. The steering assembly includes a crown attached by mechanical fasteners to blades and to a central steering portion joining the assembly to the frame of the vehicle. The parts joined are the blades (16), steerer (14), crown (12), and reinforcements (24). Mechanical fasteners serviceable with common tools provide a reinforced steering assembly of greater strength than welded or brazed constructions. This assembly allows the use of metallic, advanced composite, or thermoplastic components. Adjustments of axle location and steering geometry are made by sliding blades (16) up or down in crown (12). Blades (16), steerer (14), and crown (12) retain the original cold drawn strength of the metal used by mechanically joining without brazing or welding.
    • 一种机械接合的转向组件,用于支撑轮式车辆的车轮,用于相对于车辆的车架转向运动。 转向组件包括通过机械紧固件附接到叶片的冠部和将组件连接到车辆框架的中心转向部分。 接合的部件是叶片(16),转子(14),表冠(12)和增强件(24)。 通用工具可以使用的机械紧固件提供了比焊接或钎焊结构更强的强化转向组件。 该组件允许使用金属,高级复合材料或热塑性组件。 轴位置和转向几何形状的调整是通过在顶部(12)中向上或向下滑动叶片(16)来实现的。 叶片(16),转子(14)和表冠(12)保持原始的拉伸强度,通过机械连接而不用钎焊或焊接所使用的金属。

    • A lockable shock absorber interconnecting the upper portion of a bicycle front wheel fork with a handlebar thereabove provides releasably joinable body extending upwardly from the bicycle fork and pivotally mounting in its upper portion an elongate handlebar arm releasably carrying a handlebar in its end portion. The handlebar arm is biased in an upwardly angled orientation, but movable downwardly against its bias to absorb shock. Biasing is provided by a compression spring carried about a depending spring rod pivotally mounted in the medial portion of the handlebar arm. The lower portion of the compression spring is supported on a bracket carried by the body and the spring rod is slidably carried within a vertical hole defined in the bracket. A horizontal fastening pin slidably carried by the bracket perpendicular to the spring rod is movable from a first position locking the spring rod relative to the bracket to a second position allowing motion of the spring rod relative to the bracket.
    • 将自行车前轮叉的上部与其上面的把手相互连接的可锁定减震器提供从自行车叉向上延伸的可释放地连接的主体,并且在其上部枢转地安装有可释放地在其端部承载车把的细长手把臂。 把手臂以向上倾斜的方向偏置,但是能够抵抗其偏压向下移动以吸收冲击。 偏置由围绕可转动地安装在把手臂的中间部分中的垂直弹簧杆承载的压缩弹簧提供。 压缩弹簧的下部支撑在由主体承载的支架上,并且弹簧杆可滑动地承载在限定在支架中的垂直孔内。 垂直于弹簧杆可滑动地支承托架的水平紧固销可从第一位置移动,第一位置将弹簧杆相对于托架锁定到第二位置,允许弹簧杆相对于托架运动。
