具有空气动力学特征的高尔夫球杆和高尔夫球杆组件
相关申请
本申请要求来自2009年5月13日提交的美国申请第12/465,164号的优先权权益,其全部通过引用的方式并入。
发明领域
本发明的方面大体涉及高尔夫球杆和高尔夫球杆杆头,且特别地涉及具有空气动力学特征的高尔夫球杆杆头和高尔夫球杆。
背景
当通过高尔夫球杆撞击时,高尔夫球运行的距离大部分由与高尔夫球撞击时球杆杆头的速度决定。球杆杆头的速度接着可受风阻力或球杆杆头提供的阻力影响,特别是假定球棒的大球杆杆头尺寸。特别地,球棒、球道用木杆或金属木制球棒的球杆杆头在其摆动路径期间产生很大的空气动力学阻力。由球杆杆头产生的阻力导致球杆杆头速度减小,并从而导致在高尔夫球被击打后其运行的距离的减小。
不仅在撞击时,而且在向上摆动直到与高尔夫球撞击时的期间内,减小球杆杆头的阻力将导致球杆杆头速度的提高和高尔夫球运行距离的增加。可预期提供一种减小或克服现有已知设备中固有的一些或全部困难的高尔夫球杆杆头。对于本领域技术人员即在此技术领域内知识丰富或经验丰富的人来说,鉴于本发明的以下公开内容和一些实施方式的详细描述,特别的优势将是明显的。
概述
本发明的原理可用于提供具有改进的空气动力学性能的高尔夫球杆杆头。根据第一方面,高尔夫球杆杆头包括主体部件,主体部件具有击球面、趾部、跟部、底部和边缘,边缘在顶部和底部之间且在趾部和跟部之间延伸。在主体部件上的减阻结构设置成减小从后挥杆结尾至下挥杆的高尔夫挥杆期间对主体部件的阻力。
根据另一方面,高尔夫球杆杆头包括主体部件,主体部件具有击球面、趾部、跟部、底部和边缘,边缘在顶部和底部之间且在趾部和跟部之间延伸。大体V型的凹进部分形成在底部内并具有接近击球面和跟部并远离边缘和趾部定位的顶点。一对腿部延伸到接近趾部并远离击球面的点,并向着边缘且远离击球面弯曲。
根据再一方面,高尔夫球杆组件包括杆身和固定到杆身的第一端的球杆杆头。球杆杆头包括主体部件,主体部件具有击球面、趾部、跟部、底部和边缘,边缘在顶部和底部之间且在趾部和跟部之间延伸。连续凹槽从趾部的前部分延伸到后缘并沿着边缘的整个长度延伸。
通过提供根据一些实施方式的具有从趾部的前部分延伸到后缘并沿着边缘的整个长度延伸的连续凹槽的高尔夫球杆杆头,在高尔夫球杆杆头向前往上摆动直到与高尔夫球撞击时的期间内,高尔夫球杆杆头的阻力可被减小。这是非常有利的,因为阻力的减小将导致球杆杆头速度的增加,以及因而导致在高尔夫球被球杆杆头击打后其运行距离的增加。
其中公开的这些和其他的特征和优点将从一些实施方式的以下详细公开内容中进一步理解。

一些实施方式的详述
图1中显示高尔夫球杆10的阐示性实施方式,且该高尔夫球杆10包括杆身12和附接到杆身12的高尔夫球杆杆头14。高尔夫球杆杆头14可以是任何球棒、木制球棒或类似物。高尔夫球杆10的杆身12可由各种材料制成,比如钢、铝、钛、石墨或复合材料以及合金和/或其组合,包括传统已知的和本领域中使用的材料。另外,杆身12可以任何想要的方式附接到球杆杆头14,包括以本领域已知的和使用的常规方式(例如,通过在插鞘元件处的粘合剂或粘结剂、通过熔融技术(例如,焊接、钎焊、软焊等)、通过螺纹或其他机械连接件、通过摩擦配合、通过保持元件结构等)。在杆身12上设置有把手或其他手柄元件16以向高尔夫球手提供抓紧高尔夫球杆杆身12所利用的防滑表面。把手元件16可以任何想要的方式附接到杆身12,包括本领域已知的和使用的常规方式(例如,通过粘合剂或粘结剂、通过螺纹或其他机械连接件、通过熔融技术、通过摩擦配合、通过保持元件结构等)。
球杆杆头14包括主体部件15和插鞘16,杆身12以已知的形式附接到插鞘16。主体部件15包括多个部分或表面。如所示,此示例的主体部件15包括击球面17、顶部18、趾部20、边缘22、跟部24和底部26。边缘22相对击球面17定位并在顶部18和底部26之间且在趾部20和跟部24之间延伸。
在主体部件15上设置有减阻结构27以减小在使用者从使用者的后挥杆结束至下挥杆的高尔夫挥杆期间球杆杆头14上的阻力。减阻元件27在使用者挥动高尔夫的整个下挥杆期间提供减小的阻力,而不只是在撞击时。
在撞击高尔夫球时,击球面17大体垂直于球杆杆头14运行和高尔夫球飞行的方向。在使用者后挥杆和使用者下挥杆期间,使用者的手使高尔夫球杆10扭弯,因此引入偏转,从而枢转击球面17远离其撞击位置。由于在撞击时击球面17的方向被认为是0°,在后挥杆期间,击球面从使用者向趾部20和边缘22扭转到最大90°的偏转,此时跟部24是球杆杆头14的前缘。
在一些实施方式中,减阻结构27包括围绕球杆杆头14的外周的一部分形成的连续凹槽28。如图2-4中所示,凹槽28从趾部20的前部分30完全延伸到趾部20的后缘32,并持续到边缘22。凹槽28然后延伸穿过边缘22的整个长度。如图4中可见,凹槽28在跟部24的后部分34内逐渐变细成一端点。在一些实施方式中,在趾部20的前部分30处凹槽28可拐弯并沿着底部26的一部分延续。
在所示实施方式中,凹槽28为大体U型。在一些实施方式中,凹槽28具有大约15mm的最大深度。然而要清楚,凹槽28可具有沿其长度的任何深度。
当空气流过球杆杆头14的主体部件15的顶部18和底部26时,其往往会分离,这引起阻力的增加。凹槽28用于减小空气分离的趋势,从而减小阻力并提高球杆杆头14的空气动力学,这又增加球杆杆头的速度和击打后球将运行的距离。使凹槽28沿着趾部20延伸是非常有利的,因为如上所述,对于多数高尔夫球杆杆头14的摆动路径,球杆杆头14的前部分是跟部24,且球杆杆头14的后缘为趾部20。因而,由沿着趾部20的凹槽28提供的空气动力学的优势在多数摆动路径期间实现。沿着边缘22延伸的部分凹槽28在球杆杆头14与球撞击时提供空气动力学的优势。
在图1-6中所示的实施方式中,主体部件15为已知的方头。尽管在几何形式上不是真正的方形,但是方头主体部件15的顶部18和底部26相比于传统的圆头球杆为大体方形的。
下表中阐示了在挥杆期间通过凹槽28提供的阻力减小的示例。在表中,对方头设计并对结合凹槽28的减阻结构的方头设计两者,显示了对于整个高尔夫挥杆中偏转的不同角度的阻力值。
阻力
  偏转   90°   70°   60°   45°   20°   0°
  标准   0   3.04   3.68   8.81   8.60   8.32
  W/凹槽   0   1.27   1.30   3.25   3.39   4.01
可以看到,撞击时,在偏转角为0°的情况下,对于具有凹槽38的方形球杆杆头的阻力为方形球杆杆头阻力的大约48.2%(4.01/8.32)。然而,对于方形球杆杆头,整个挥杆期间总阻力的合力提供544.39的总阻力,而对于具有凹槽38的方形球杆杆头的总阻力为216.75。因此,对于具有凹槽38的方形球杆杆头的总阻力为方形球杆杆头的总阻力的大约39.8%(216.75/544.39)。因此,合并整个挥杆期间的阻力比起只计算撞击时的阻力可产生很不相同的结果。
在一些实施方式中,如图5-6中所示,在底部26内形成了凹进部分36。在所示实施方式中,凹进部分36为大体V型,且其形状的顶点38接近击球面17和跟部24定位。即,顶点38接近击球面17和跟部24并远离边缘22和趾部20定位。凹进部分36包括延伸到接近趾部20并远离击球面17的点并向边缘22且远离击球面17弯曲的一对腿部40。
多个辅助凹进部分42形成在凹进部分36的底面43内。在所示实施方式中,每个辅助凹进部分42是规则的梯形,具有其更接近跟部表面24的较小的底边44和更接近趾部表面20的较大的底边46,以及使较小的底边44连接到较大的底边46的成角度的侧边45。在所示实施方式中,每个辅助凹进部分42的深度从其位于较小的底边44的最大值变化到较大的底边46,较大的底边46与凹进部分36的底面43齐平。
图7-10中显示球杆杆头54的另一实施方式。球杆杆头54具有更传统的圆头形。要清楚,术语“圆头”不是指完全圆形的杆头,而是具有大体或基本上圆形的轮廓的杆头。
围绕球杆杆头54的外周的一部分形成有连续凹槽28。如图7-10中所示,凹槽28从趾部20的前部分30完全延伸到趾部20的后缘32,并持续到边缘22。凹槽28然后延伸穿过边缘22的整个长度。如图4中可见,凹槽28在跟部24的后部分34中逐渐变细成一端点。
因此,虽然已经显示、描述并指出了各种实施方式基本的新颖特征,但是要理解,所示设备的形式和细节上及其操作中的各种省略、替换和变化可以由本领域技术人员做出,而不偏离本申请的精神和范围。例如,特别是旨在以大体相同的方式执行大体相同的功能以实现相同结果的这些元件和/或步骤的所有组合在本发明的范围内。从一个所述实施方式到另一个所述实施方式的元件的替换也是完全预期和考虑的。因而,其旨在仅受其所附权利要求的范围所示的限制。
