Description

高尔夫球杆和镇重系统
技术领域
本发明涉及高尔夫球杆，特别涉及一种提高性能、提高重量灵活性和降低生产成本的高尔夫球杆头和镇重方法。
相关技术
重量在一高尔夫球杆中的位置和分布是影响该高尔夫球杆性能的一个重要因素。特别是，重量集中在高尔夫球杆头的底部可降低重心、击球时有助于把高尔夫球推入空中；而重量集中在高尔夫球杆头的尖头和跟部在击球时可抗扭曲或提高转动惯量。低重心和高转动惯量都是影响高尔夫球杆使用性和手感的重要性能变量。人们用各种设计改变高尔夫球杆头中的重量位置和分布。这些设计之一是在高尔夫球杆头中组合使用高密度和低密度材料以及组合使用这些材料的方法。
在制作高尔夫球杆头中使用多种材料的一个例子是把一种高密度材料装到低密度材料高尔夫球杆头上。如Helmstetter等人的美国专利No.5,776,010所示，用摩擦配合、紧固件或螺丝之类机械手段把方形或异形高密度材料装到高尔夫球杆头中一对应凹座中。尽管能提高性能，但必须对方形高密度材料和对应凹座进行公差精确的机加工，从而生产成本提高。
镇重高尔夫球杆的另一个例子是把一高密度流体倒入高尔夫球杆中一储槽中。由于流体能顺着储槽的内部形状流动，因此无需机械连接或粘结就可确保镇重材料在高尔夫球杆中的位置精确。这种方法的一个缺点是高密度材料的熔点必须比球杆头材料低。此外，随着处理温度的提高，所使用设备的温度提高，能耗增加，因此成本增加。由于镇重材料必须满足低熔点、高密度的条件，因此这种方法的应用受到限制。
为了克服使用单种材料的不足，出现了多成分镇重系统，这些系统组合使用高密度材料与聚合物之类载体流体。特殊形式的高密度材料与载体流体混合后倒入高尔夫球杆的储槽中，然后载体流体在存储储槽中固化成复合镇重材料。最普通的材料包括热定形聚合物载体流体如环氧树脂，环氧树脂在常温下就可作处理和固化高密度材料与环氧树脂的混合物。与环氧树脂不同，聚丙烯之类热塑聚合物载体流体需要加热成液态后在常温下冷却成固态，并能重新加热成液态。多成分镇重系统的一个缺点是载体材料的密度低、通常为1g/cm3，因此为获得双材料镇重的所需高密度，镇重材料与载体流体的比例必须很大。为确保双材料镇重结成一块，载体流体还用作镇重材料的粘合剂。
多成分镇重系统的一个缺点是较之镇重材料必须使用少量载体流体，从而在双材料镇重中造成气泡并因此粘合得不牢。增加载体流体的数量可使两种材料混合得更充分，但密度降低。因此，需要提供一种双材料镇重，它含有较高密度载体流体，以提高重量在高尔夫球杆头中的分配的灵活性，同时降低生产成本。还需要提供一种能容纳双材料镇重并且双材料镇重位置可变的高尔夫球杆头。
本发明概述
本发明解决高尔夫制造业的问题，为此提供一种双材料镇重和一种高尔夫球杆头，它们组合使用时可获得重心降低、手感和使用性优良的一种高尔夫球杆。本发明双材料镇重的一个突出特征是使用震动能量使高密度材料与低密度材料充分接触。该实施例减小或消除混合密度不同材料时会发生的气泡，使得高密度材料和低密度材料移动到高尔夫球杆头中最佳位置。
在一优选实施例中，双材料镇重为由非连续相的高密度金属材料和连续相的低密度金属材料构成的非均质混合物。金属材料最好选择密度高、与金属兼容、市场上常见的材料以及长期环境稳定性良好的许多合金。高密度材料可选择铜金属、黄铜金属、钢和钨金属；而低密度金属可选择熔点低的几种焊料。在一优选实施例中，许多钨球用作非连续相的高密度材料，铋-锡焊料用作连续相的低密度材料。为获得非均质混合物，使低密度材料成为液态，然后用震动能减小或消除气泡，使高密度金属材料移动到高尔夫球杆头中最佳位置，然后固化低密度材料。
一般结合一种称为铁头球杆的高尔夫球杆说明本发明一优选实施例。在这种高尔夫球杆中，有一种称为背腔铁头球杆的公知铁头球杆，其后表面外周上有材料的连续围带或凸缘。这一结构在该铁头球杆的后部或背部生成一开口空腔或第一空腔，而在该铁头球杆前表面或击球表面生成一较大“最有效击球点”，从而击球面积较大。位于该开口空腔下方、伸展在尖头与跟部之间、高尔夫球底部周边旁的该材料的围带包括一也称为第二空腔或容纳镇重材料的镇重袋的内部空腔。该内部空腔包括至少一个通入内部空间的进口，在一顶壁与一底壁之间有一垂直尺寸，在该高尔夫球杆头的一尖头区与一跟部区之间有一水平尺寸。在一优选实施例中，该内部空腔的内部形状或构型使得镇重可位于该尖头区或跟部区，帮助高尔夫球手相对预定目标线打开或关闭高尔夫球杆头。确切说，位于尖头区的镇重帮助打开高尔夫球杆头，位于跟部区的镇重帮助关闭高尔夫球杆头。此外，该内部空腔的中央体积部扩大，在双材料镇重中形成垂直密度过渡区，使得击球时的手感更佳。
在一优选实施例中，如作为参考材料包括在此的Schmidt等人的美国专利No.5,282,625所述，该高尔夫球杆前表面后方有一切槽。该切槽用来把重量移向该高尔夫球杆头的后周边区，从而除了背腔铁头球杆固有的“最有效击球点”的改进，还扩大了“最有效击球点”。此外，后移双材料镇重有助于在击球时把高尔夫球推入空中，从而提高了高尔夫球杆的使用性。
因此，本发明的一个目的是提供高尔夫球杆的一种双材料镇重系统，该系统可更灵活地改变重心位置，使高尔夫球杆的手感更好。
本发明的另一个目的是赋予高尔夫球杆的双材料镇重系统震动能，从而使得连续相和非连续相的两镇重材料混合得更充分、定位更精确。
本发明的另一个目的是提供一种具有一内部空腔的高尔夫球杆头，该空腔中央的垂直尺寸扩大，从而高密度材料在高尔夫球杆头中央中的位置精度更高。
本发明的再一个目的是提供一种具有一空腔的背腔钛合金铁头球杆，该空腔中有许多钨合金球和一铋-锡焊料。

    本发明最佳实施方式
如图1-8所示，本发明一高尔夫球杆总的用标号12表示。该高尔夫球杆头12包括一主体13，该主体包括一跟部14、一底部16、一尖头部18、一顶部20和一插口22。跟部、尖头、底部和顶部14、18、16和20只用来总的说明高尔夫球杆头12的各部分，它们可彼此重叠。高尔夫球杆12还包括一嵌入壁24、一进口26、一内部空腔28、一空腔凸缘30、一后表面32、一开口主后腔33和从该后表面的跟部14伸展到尖头部18的一系列轮廓线34。内部空腔28位于后凸缘30中，一般在底部16旁从跟部14伸展到尖头部18。在一优选实施例中，一跟部壁44(图1中虚线所示)和一尖头壁52(图1中虚线所示)界定内部空腔28的横向范围。该内部空腔28的体积为5-25立方厘米，最好为9-15立方厘米。该内部空腔的长度和体积使我们可灵活设置本发明双材料镇重的位置以控制重心位置，从而在高尔夫球杆头击打高尔夫球时提高手感。
该高尔夫球杆头12还包括供一球柄(未示出)插入的插口进口和插口出口36和42、一击打高尔夫球(未示出)的表面38和一组刻痕线40。
如图9-11所示，本发明高尔夫球杆总的用标号12表示。该高尔夫球杆12还包括跟部壁44、一底壁45、一下部表面厚度46、一切槽47、一前壁48、一顶壁49和一上部表面厚度50。在一优选实施例中，内部空腔28的边界由下部表面厚度46、上部表面厚度48、顶壁49、底壁45、嵌入壁24、跟部壁44和尖头壁52(图10所示)界定。底壁45与顶壁49之间的距离由一间隙51界定，该间隙在跟部壁44处有第一最小值，在尖头壁52处有第二最小值(如图10所示)。
内部空腔28在跟部壁和尖头壁44和52旁的体积可减小，因为镇重在这两个部位的有效性比相同镇重在内部空腔28中央的有效性高。在一优选实施例中，间隙51在跟部壁44与尖头壁52(如图10所示)之间达到最大值，生成一垂直密度过渡区，从而击球时手感更佳。下部表面厚度46小于上部表面厚度50，以减轻高尔夫球杆头12的重量，使得更多重量移到内部空腔28，而又确保下部表面厚度46有足够的结构强度。在一优选实施例中，内部空腔28的进口26位于嵌入壁24上并用一椭圆形浮雕(未示出)盖住。在一优选实施例中，高尔夫球杆头12用钛合金制成。
图12为本发明一方法实施例的高尔夫球杆头12的剖面图。高尔夫球杆头12称重后把预定重量的第一镇重材料54加到内部空腔28中。在一优选实施例中，第一镇重材料54占内部空腔28的10％-40％。在一优选实施例中，第一镇重材料54为一种密度高、与钛和钢之类结构金属兼容性好、环境稳定性高、市场上常见的金属材料。第一镇重材料54举例说有铜金属、黄铜金属、钢和钨金属。在一优选实施例中，第一镇重材料54的密度大于12g/cm3，最好为12g/cm3-20g/cmU。在一优选实施例中，第一镇重材料54包括钨合金球，其密度为18g/cm3，直径大于3mm，灌入高尔夫球杆头12的内部空腔28中。直径之所以要大于3mm，是为了在钨球之间生成有效流体路径，确保获得高密度镇重块。高尔夫球杆头12和第一镇重材料54的温度升高到足以使第二镇重材料60(如图14所示)保持液态。在一优选实施例中，用一连续炉把高尔夫球杆头12和第一镇重材料54的温度升高到至少350°F。尽管可使用各种加热方法，但最好把含有钨合金球的高尔夫球杆头12放置在一在一24英寸的加热区中以5.5英寸/分钟速度移动的传送带上。
加热后把含有钨合金球的高尔夫球杆头12固定在图13所示夹具56上。然后如图14所示把第二镇重材料60灌入高尔夫球杆头12的内部空腔28中。在一优选实施例中，第二镇重材料60的密度小于14g/cm3，最好为6g/cm3-10g/cm3。在一优选实施例中，第二镇重材料60为密度为8.6g/cm3、加热到至少350°F的液态的铋-锡焊料。镇重方法可包括与把高尔夫球杆头12和第一和第二镇重材料56和60加热成成品有关的任何组合数。夹具56上装有用来测量添加第二镇重材料60时高尔夫球杆头12总重量的秤58。在一优选实施例中，在整个镇重方法中使用秤58，以确保合适数量的第一和第二镇重材料54和60加到高尔夫球杆头12中。
如图15所示，用一夹子62使高尔夫球杆头12紧抵夹具56和一安装台64。安装台64用来把高尔夫球杆头12倾斜成第一镇重材料在震动能作用下移动到内部空腔28中最低点所需方向。可用机械装置、超声波、辐射或任何其他赋予震动能的装置实现高尔夫球杆头12和双材料镇重70(如图16所示)的震动能处理。在一优选实施例中，一机械震动装置使高尔夫球杆头12发生小振幅震动。震动开始和结束时间对本发明至关重要。受震动时第二镇重材料60应保持液态，以防止第一镇重材料54生成气泡或移出到第二镇重材料60外部。在一优选实施例中，震动历时约20秒。震动处理完成后，冷却高尔夫球杆头12，使第二镇重材料60固化。可用制冷、浸入水之类冷却流体中或只是把高尔夫球杆头12自然冷却到室温实现双材料镇重70的冷却。在一优选实施例中，一空气喷嘴68向高尔夫球杆头12提供冷却空气。
图16示出高尔夫球杆头12中有由第一镇重材料54和第二镇重材料60构成的双材料镇重70。高尔夫球杆头12可有反映制造高尔夫球杆头12时初始重量变化范围。图17示出高尔夫球杆头12吸纳这变化的比重，该表列出本发明5号铁头球杆中使用的第一和第二镇重材料54和60的比例。
如图18所示，本发明另一实施例为一包括内部空腔28和双材料镇重70的木制结构高尔夫球杆头12。内部空腔28的位置不限于图18所示位置，为调节影响到手感和使用性的重心，可位于高尔夫球杆头12中其他位置。
图19和20示出一轻击球杆头112。该轻击球杆头有一包括一表面插入物114的主体113。插入物114位于一前方凹座116中。该主体113还有一在其中放置双材料70的内部空腔128。双材料70由最好为钨球的第一材料54和最好为铋-锡焊料的第二材料60构成。在一优选实施例中，第一金属材料均匀分布在内部空腔128的尖头端116和跟部端114中。
