Description
优先权要求
本申请要求于2008年4月10日递交的12/101,101号美国专利申请的优先权。
技术领域
本公开总体上涉及高尔夫装备,更具体地涉及高尔夫推杆头、制造高尔夫推杆头的方法以及与高尔夫推杆头一同使用的可拆卸配重。
背景技术
由高尔夫杆头产生的惯性矩(MOI)受到位于包括推杆头在内的高尔夫球杆头中的配重量与配重分布的影响。由于增加高尔夫球杆头的MOI会提高在偏心击球过程中对不希望出现的高尔夫球杆头扭转的抵抗,从而个人使用高尔夫球杆头的成绩可能受MOI影响。因此,增加高尔夫球杆头的MOI可在偏心击球过程中提供更大的容错性。因此,普遍期望增加高尔夫球杆头的MOI,在某种意义上(和至某程度)来说这也是特定个人所期望的。
发明内容
为了满足对增加高尔夫球杆头的MOI的需求,提出了本申请。
根据本申请的一个方面,提供了一种球杆头,包括:一个或多个可拆卸配重,位于所述球杆头的底部中;以及减振合成物,置于所述一个或多个可拆卸配重中的至少一个与所述球杆头的表面之间。
根据本申请的另一个方面,提供了与球杆头一同使用的成套可拆卸配重,其中所述成套可拆卸配重包括适于可翻转地附接在所述球杆头上的多个可拆卸配重,其中(a)所述多个可拆卸配重包括至少两种配重,每一种具有不同的比重,以及(b)所述多个可拆卸配重中的每一个具有大致相同的体积。
根据本申请的又一个方面,提供了一种用于制造高尔夫推杆头的方法,包括:(a)形成高尔夫推杆头,其中所述高尔夫推杆头包括适于容纳一个或多个可拆卸配重的底部;以及(b)将所述一个或多个可拆卸配重置于所述底部中,其中减振合成物置于所述一个或多个可拆卸配重中的至少一个与所述高尔夫推杆头的表面之间。
根据本申请,可以相对于无可拆卸配重的高尔夫球杆头增加或者改变高尔夫球杆头的MOI。进一步地,可以在高尔夫推杆头的所需位置添加所需量的配重,以便影响推杆的总体重量、MOI、重量的分布或其组合。

具体实施方式
在此总体上描述了与高尔夫球杆头有关的制造方法、设备和物品。在此所描述的制造方法、设备和物品不限于此。
在图1至8的示例中,高尔夫推杆头100可包括底部105、用于撞击高尔夫球(未图示)的面部110、后部115以及两个侧部120,其中面部110在此也被称作击打面。高尔夫推杆头100还可包括趾部125以及跟部130。高尔夫推杆头100可进一步包括适于容纳杆柄(未图示)一端的插鞘(hosel)部135。在一个示例中,高尔夫推杆头100可由钢材或者基于钢的材料通过铸造工艺、锻造工艺、二者的组合或者其它适当的制造工艺而制成。
参照图1和2,例如高尔夫推杆头100可设置有多个可拆卸配重140,可置于至少一个容置可拆卸配重140的空洞中。例如,高尔夫推杆头100可在其趾部125和跟部130设置有多个可拆卸配重140中的一个或多个,其中每一个可拆卸配重140可任选地置于形成于高尔夫推杆头中的相同或不同空洞中。通过将一个或多个可拆卸配重140置于高尔夫推杆头100的趾部125和跟部130,高尔夫推杆头100的MOI可以相对于无可拆卸配重140的高尔夫推杆头100的MOI增加或者改变。
根据某些实施方式,高尔夫推杆头100可进一步包括置于高尔夫推杆头100的中心部190附近的第三可拆卸配重。置于高尔夫推杆头100的中心部190附近的第三可拆卸配重可任选地由个人用于增加由高尔夫推杆头100产生的总质量以及动量。
参照图3-6,可在可拆卸配重140与高尔夫推杆头100之间放置减振合成物145。减振合成物145可由能够减小不希望出现的噪声和振动的任何材料构成,如聚氨酯、橡胶、泡沫、塑料、弹性体或以上材料的组合。不希望出现的噪声和振动可能由金属与金属的接触(例如可拆卸配重140中的一个与高尔夫推杆头100之间的接触)而产生。
可拆卸配重140可放置在高尔夫推杆头100的底部105(如图1所示)和/或后部115中。可拆卸配重140可以利用任何适当的装置可翻转地固定在高尔夫推杆头100上。例如,通过用穿过位于可拆卸配重140中的孔155(图2)的螺丝150将可拆卸配重140可翻转地附接 在底部105上,可将可拆卸配重140置于底部105中(如图1所示)。根据这样的实施方式,螺丝150可由位于高尔夫推杆头100的主体中(例如位于高尔夫推杆头100的底部105中)的螺纹孔160容纳。如图6所示,例如,高尔夫推杆头100可包括适于容纳在此所描述的可拆卸配重140的一个或多个空洞175,并且减振合成物145可置于可拆卸配重140与上述空洞175的内表面之间。
参照图7和8,还可通过磁力将可拆卸配重140固定在高尔夫推杆头100上。例如,可将可拆卸配重140置于形成于高尔夫推杆头100中(例如形成于高尔夫推杆头100的底部105中)的空洞175中。可将磁体180附接并置于空洞175中。类似于在此所述的其它实施方式,可在可拆卸配重140与空洞175的内表面之间放置一层减振合成物145。高尔夫推杆头100可进一步包括开放式凹腔(open pocket)185,其可用于将可拆卸配重140从空洞175中提起以及减弱将可拆卸配重140保持在空洞175中的磁力。根据这些实施方式,可拆卸配重140可至少部分地或者完全地由会磁性吸附在磁体180上的材料构成。
可拆卸配重140可呈现任何适当的形状和构形(shape andconfiguration),比如正方形、卵形、椭圆形、圆形、矩形或者其它构形。在圆形的可拆卸配重140的情况下,其侧面可具有螺纹,使得圆形可拆卸配重140可以置于并旋紧在形成于高尔夫推杆头中并具有对应螺纹的至少一个空洞中。当采用其它形状的可拆卸配重140时,比如正方形、卵形、椭圆形、矩形或其它构形,可拆卸配重140例如可在其底侧包括单独的圆形螺纹突起,该圆形螺纹突起可旋紧在形成于高尔夫推杆头中的对应空洞中。可选择地,如图5和6所示,可利用单独的螺丝150将可拆卸配重140可翻转地附接在高尔夫推杆头上。
参照图2,根据某些实施方式,可拆卸配重140可呈三角形,例如类似于直角三角形的三角形。参照图1,根据这些实施方式,当三角形可拆卸配重140例如置于高尔夫推杆头100的底部105中时,三角形可拆卸配重140的直角边可大致平行于高尔夫推杆头100的后侧壁165和侧壁170,而其斜边面向高尔夫推杆头100的面部110。根据这样的实施方式,由可拆卸配重140提供的重量的主要部分朝向后部 105和侧部120布置,这可起到增加高尔夫推杆头100的MOI的作用。
换言之,参照图10,如图10(A)所示,可将呈直角三角形(即,具有包括大致90度角的部分的三角形)的可拆卸配重140置于高尔夫球杆头的后部和侧部。换言之,如图10(A)所示,呈三角形的可拆卸配重140可具有包括大致90度角的部分,其置于底部的侧部120中并远离球杆头的击打面。这种定向将可拆卸配重140的重量中的大部分朝向高尔夫推杆头的后部105(和侧部120)放置,从而与包括如图10(B)-(D)所示以其它定向布置的可拆卸配重140的高尔夫推杆头相比,这种定向起到给高尔夫推杆头提供更大的MOI的作用。
多个可拆卸配重140可选自一组可拆卸配重140,比如2、3、4、5、6、7、8、或更多可拆卸配重140。另外,多个可拆卸配重140可选自多对可拆卸配重140,比如2、3、4、或更多对可拆卸配重140。可拆卸配重140可制造成具有不同的比重,以便于个人可以选择具有所需比重的可拆卸配重140以将其安装在高尔夫推杆头100中。
多个可拆卸配重140可具有大致相同的体积。另外,多个可拆卸配重140可具有大致相同的体积和几何形状。更具体地,根据这样的实施方式,每一个可拆卸配重140可具有唯一的(unique)比重,而具有大致相同的体积和几何形状。通过采用不同材料或其组合来制造可拆卸配重140,可使可拆卸配重140具有不同的比重,而保持大致相同的体积和几何形状。
可采用各种方法和合成物中的任一种对与在此所述的高尔夫推杆头100一同使用的每一个或每一对可拆卸配重140给予不同的比重。例如,可采用各种量的钨粉结合适当的材料例如其它类型的金属、聚合物、塑料、弹性体、或者这些材料的组合来制造可拆卸配重140。根据这样的实施方式,由于在此所述的多个可拆卸配重140可设计成具有大致相同的体积,那么可以增加用于制造特定可拆卸配重140的钨粉量以提高该可拆卸配重140的比重。相反,可以减少用于制造特定可拆卸配重140的钨粉量以降低该可拆卸配重140的比重。这样,可利用各种量的钨粉来制造多个可拆卸配重140,以便生产出具有一定比重范围的一组可拆卸配重140。
除了在此描述的高尔夫推杆头外,其它实施方式还包括高尔夫推杆。更具体地,本申请还提供包括在此所述的高尔夫推杆头的高尔夫推杆,该高尔夫推杆设置有高尔夫球杆柄(shaft)和握把。插鞘135可容纳杆柄(未图示)的第一端以形成具有高尔夫推杆头100的高尔夫推杆。可通过粘合工艺和/或其它适当的连接工艺(例如,机械连接、软钎焊、焊接和/或硬钎焊)将杆柄和插鞘135彼此固定。握把(未图示)可容纳杆柄的第二端以制成高尔夫推杆。可通过粘合工艺和/或其它适当的连接工艺将杆柄和握把彼此固定。制造方法、设备和物品不限于此。通过采用铸造工艺制造本文所述的高尔夫推杆头100,可以较为方便地改变高尔夫推杆头100的形状和尺寸以及制出用于容纳本文所述的可拆卸配重140的空洞175。
根据另外的实施方式,本申请提供用于与本文所述的高尔夫推杆头100一同使用的成套可拆卸配重。成套可拆卸配重包括适于可翻转地附接在高尔夫推杆头上的多个可拆卸配重。如本文所述,成套可拆卸配重可包括具有不同比重的至少两个配重。更具体地,在某些实施方式中,成套可拆卸配重可包括1、2、3、4、5或更多对可拆卸配重,其中每对具有不同的比重。根据这样的实施方式,个人可基于用在他或她的高尔夫推杆头上的配重的特定重量来选择所需的可拆卸配重对或可拆卸配重组合。成套可拆卸配重可允许个人在高尔夫推杆头的跟部、趾部和/或中部添加所需量的配重,以便影响推杆的总体重量、MOI、重量的分布或其组合。
如本文所述的其它实施方式,包含在任意给定的成套配重中的配重可以具有大致相同的体积以使得这些配重看起来相同并与高尔夫推杆头中尺寸相似的空洞相适合,但仍旧可以具有不同于其他可拆卸配重的比重。另外,成套可拆卸配重可包括适于放在可拆卸配重与高尔夫推杆头之间的某些减振合成物。这种减振合成物的非限制性示例包括聚氨酯、橡胶、泡沫、塑料、弹性体及其组合。减振合成物例如可构造成个人可将其插入高尔夫推杆头的空洞中的一层减振材料,使得可拆卸配重然后可以被置于空洞中,这样这层减振材料就居于高尔夫推杆头的主体与可拆卸配重之间。更具体地,例如,参照图3和6, 减振合成物145可构造成垫片,该垫片在其中心部分包含孔(未图示)。螺丝150可以穿过该孔以将可拆卸配重140和减振合成物145固定到位于高尔夫推杆头100中的空洞175。更进一步地,减振合成物145可牢固地附接在可拆卸配重的表面上,而当置于高尔夫推杆头中时减振合成物145与高尔夫推杆头的表面接触。可利用例如粘接剂或其它化学或机械连接方法将减振合成物145牢固地附接在可拆卸配重的表面上。
如以上关于其它实施方式的所进行的描述,包含于成套配重中的可拆卸配重可具有适于可翻转地附接在高尔夫推杆头上的任何尺寸、形状或构造。在某些实施方式中,可拆卸配重呈三角形并适于被可翻转地附接到高尔夫推杆头的底部105上。如果高尔夫推杆头包括螺纹孔、空洞、凹陷、和/或能够牢固地容纳可拆卸配重的其它装置或尺寸,那么包含于成套配重中的可拆卸配重可适于例如通过螺丝、Velcro 尼龙搭扣材料或其它机械接合装置而固定在高尔夫推杆头上。在另一些实施方式中,包含于成套配重中的可拆卸配重可适于通过磁力固定在高尔夫推杆头上。例如,高尔夫推杆头的可拆卸配重可包括磁体。另外,可拆卸配重或者高尔夫推杆头(任何一个部件均不包括磁体)至少部分地包括会被磁体吸引的材料,比如17-4不锈钢。例如,高尔夫推杆头可设置有磁体,而可拆卸配重至少部分地包括17-4不锈钢。
可利用各种材料中的任何一种或其组合来制造可拆卸配重以制成具有一定比重范围的成套配重,同时维持可拆卸配重的体积大致不变。例如,第一对配重可由比重大致为7.7的不锈钢制成。第二对配重可由最终比重大致为12.4的钨粉和不锈钢的组合制成。第三对配重可由钨粉和不锈钢的组合制成,使得该第三对配重的每一个配重所包含钨粉的重量大于第二对配重中的配重,并使最终比重大致为17。可拆卸配重可由任何材料或任何材料的组合制成,从而使得最终比重可以根据需要进行调整。其它材料的非限制性示例包括黄铜、包含特定量的钨粉的注模聚氨酯部件以及类似合成物。
根据这样的实施方式,个人可选择所需的配重对用在高尔夫推杆头上。另外,个人如果希望用在高尔夫推杆头100的趾部125的配重 比用在跟部130的配重重或者轻,那么这个人可选择来自于不同配重对的可拆卸配重并将其用在高尔夫推杆头上。
根据这些实施方式,成套可拆卸配重可随高尔夫推杆头一起向消费者销售,或者还可以与高尔夫推杆头分开向消费者销售。再进一步地,消费者比如可通过网站选择包含于成套可拆卸配重中的不同可拆卸配重对。消费者可以在网站中确定他或她所希望购买的与特定高尔夫推杆头一同使用的1、2、3、4、或更多对可拆卸配重(或单独的可拆卸配重)。成套可拆卸配重可进一步包括用于将可拆卸配重可翻转地固定在高尔夫推杆头上的附接装置,比如扳手,该扳手被合适地构造成便于例如将螺丝150附接并旋紧在高尔夫推杆头100上以便将可拆卸配重附接在高尔夫推杆头上。
根据再进一步的实施方式,本申请提供用于制造高尔夫推杆头的方法。根据这些实施方式,例如采用金属铸造方法、锻造方法或二者的组合形成高尔夫推杆头。高尔夫推杆头被形成为包括适于容纳本文所述的可拆卸配重140的区域,并可包括位于高尔夫推杆头的后侧或底部的一个或多个单独的区域,比如位于其底部的一个或多个空洞175。更具体地,单独区域可位于高尔夫推杆头的跟部、中部、趾部或者跟部、中部或趾部之间的部分,还可以位于高尔夫推杆头的底部和/或后侧。如图1、5和6所示,例如,高尔夫推杆头可包括位于高尔夫推杆头100的每个侧部120中的区域,比如用于容纳可拆卸配重140和螺丝150的空洞175。
接着,将一个或多个可拆卸配重140安装在高尔夫推杆头中。安装过程可采用螺丝(比如图5所示的螺丝150)、磁力(图7和8)或者其它方法。根据这些方法安装在高尔夫推杆头中的可拆卸配重140可选自包括具有不同比重的多个不同可拆卸配重构件140的成套可拆卸配重140。类似于本文所述的其它实施方式,包括在成套可拆卸配重构件中的每个可拆卸配重140可具有实质上相同的体积。因此,可从成套可拆卸配重构件中选择合适的可拆卸配重构件140,并将其安装在高尔夫推杆头中。
制造高尔夫球杆头的方法可进一步包括将杆柄附接到插鞘135 上。可采用粘合工艺(例如环氧树脂)和/或其它适当的连接工艺(例如,机械连接、软钎焊、焊接和/或硬钎焊)将杆柄与插鞘135彼此固定。握把(未图示)可容纳杆柄的第二端以制成高尔夫球杆。可采用粘合工艺和/或其它适当的连接工艺将杆柄和握把彼此固定。制造方法、设备和物品不限于此。
参照图9,在某些另外的实施方式中,用于制造高尔夫推杆头的方法进一步包括接收来自顾客的订单195,该订单确定了顾客希望添加到高尔夫推杆头的配重量以及添加该配重的所需位置。可采用在线方式、传真、常规邮件、电话或其它通信手段将订单直接或间接地提交至高尔夫推杆制造商。接着,制造高尔夫推杆头200。应该理解,可在接收来自顾客的订单195之前或之后制造高尔夫推杆头。高尔夫推杆头可包括适于容纳另外的配重构件的区域,比如位于本文所述的高尔夫推杆头100的侧部120中的空洞175。再接着,将一个或多个配重构件安装在高尔夫推杆头的指定区域中205。根据所接收的订单195,一个或多个配重构件可具有与顾客希望添加到高尔夫推杆头上的配重量大致相同的重量。
尽管图1和3-8示出了(亚利桑那州凤凰城的PING公司的)Anser 高尔夫推杆头,但是本文所述的制造方法、设备和物品可容易地应用在其它类型的高尔夫推杆头上。例如,本文所述的制造方法、设备和物品可应用于镰刀型推杆(mallet putter)、刀背式推杆(blade putter)和其它类型的推杆。本文所述的制造方法、设备和物品不限于此。
尽管本文描述了某些示例性制造方法、设备和/或物品,但是本公开所覆盖的范围不限于此。相反,本公开覆盖所有字面上或者根据等价原则完全落入所附权利要求的范围内的制造方法、设备和/或物品。
