    • A golf club head comprising an aerodynamic hosel is disclosed herein. In one embodiment, the hosel may have an airfoil cross-section with a high thickness to chord ratio. In a further embodiment, the thickness to chord ratio may increase from a hosel head connection point to a hosel shaft connection point. In another embodiment, a shaft connection point of the hosel is closer to a club face vertical plane than to a head connection point vertical plane, e.g., is swept. In yet another embodiment, the hosel has an endplate proximate a shaft connection point. In yet another embodiment, the exterior surface of the hosel is rough, comprises at least one vertex generator, comprises a fillet, or comprises at least one trip step.
    • 本文公开了一种包括空气动力学插鞘的高尔夫球杆头。 在一个实施例中,插鞘可以具有具有高厚度和弦比的翼型横截面。 在另一实施例中,厚度与弦比可以从插鞘头连接点到插鞘轴连接点增加。 在另一个实施例中,插鞘的轴连接点比头连接点垂直平面更靠近球杆面垂直平面,例如被扫过。 在另一个实施例中,插鞘具有靠近轴连接点的端板。 在另一个实施例中,插鞘的外表面是粗糙的,包括至少一个顶点发生器,包括圆角,或包括至少一个跳闸步骤。

    • A golf club head comprising an aerodynamic hosel is disclosed herein. In one embodiment, the hosel has an upper portion and a swept transition portion which connects to the golf club head, and all points at which the swept transition portion contacts the club head are spaced rearwardly from a vertical face plane. In a further embodiment, both the upper portion and the swept transition portion comprise coaxial shaft receiving bores. In yet another embodiment, the swept transition portion of the hosel has a trailing edge that is truncated, or that has one or more surface discontinuities. In yet another embodiment, the swept transition portion has a height and a diameter, each of which is less than or equal to one inch.
    • 本文公开了一种包括空气动力学插鞘的高尔夫球杆头。 在一个实施例中,插鞘具有连接到高尔夫球杆头的上部部分和扫掠过渡部分,并且扫掠过渡部分接触球棒头部的所有点与竖直面平面间隔开。 在又一个实施例中,上部和扫过的过渡部分均包括同轴轴接收孔。 在另一个实施例中,插鞘的扫掠过渡部分具有被截断的后缘或具有一个或多个表面不连续性的后缘。 在另一个实施例中,扫过的过渡部分具有高度和直径,每个高度和直径小于或等于一英寸。
