圖1展示根據本發明製備的高爾夫球在長擊桿擊球後的軌跡與不同類型的高爾夫球的軌跡的對比；圖2展示根據本發明製備的高爾夫球在劈起桿擊球後的軌跡；圖3是根據圖1和2的示例性實施方式的高爾夫球。1 shows a comparison of the trajectory of a golf ball prepared in accordance with the present invention after striking a shot with a trajectory of a different type of golf ball; FIG. 2 shows a trajectory of a golf ball prepared in accordance with the present invention after a hitting of a golf club; FIG. 3 is a golf ball according to the exemplary embodiment of FIGS. 1 and 2.

具體實施方式detailed description

總體上，本發明涉及一種具有可變初速度的高爾夫球，所述可變初速度與用不同桿頭速度的長擊桿擊球有關。當以桿頭速度小於100英里/小時的長擊桿擊球時，披露的高爾夫球的結構可以使高爾夫球經受一個與目前市場上的優質高爾夫球類似的初速度。然而，以桿頭速度高於125英里/小時的長擊桿擊球時，同樣的高爾夫球可以經受高於目前市場上的優質高爾夫球的初速度。因而，披露的高爾夫球可以具有不同的與不同桿頭速度有關的初速度。In general, the present invention relates to a golf ball having a variable initial velocity associated with hitting a ball with a different head speed. When hitting with a putter with a head speed of less than 100 mph, the disclosed golf ball structure can subject the golf ball to an initial velocity similar to that of a premium golf ball currently on the market. However, when hitting with a putter with a head speed of more than 125 mph, the same golf ball can withstand the initial speed of a premium golf ball on the market today. Thus, the disclosed golf ball can have different initial velocities associated with different head speeds.

圖1-2展示高爾夫球100的示例性的實施方式。在圖1中，休閒型高爾夫球手142使用長擊桿144從發球台148上的開球球座146擊打高爾夫球100和另一種類型的高爾夫球，即高爾夫球182。作為典型的休閒型高爾夫球手，高爾夫球手142以桿頭速度低於100英里/小時擊打高爾夫球100和高爾夫球182。圖1說明各高爾夫球被長擊桿144擊球後，高爾夫球100的軌跡150和高爾夫球182的軌跡180之間的對比。 由於每個高爾夫球具有與低於100英里/小時桿頭速度的長擊桿144擊球有關的相似的初速度，每個高爾夫球具有類似的軌跡長度。低於100英里/小時桿頭速度的長擊桿144擊球後，由於高爾夫球100具有與高爾夫球182相似的初速度，軌跡150與軌跡180延伸大致相同的長度。1-2 show an exemplary embodiment of a golf ball 100. In FIG. 1, the casual golfer 142 uses the driver 144 to strike the golf ball 100 and another type of golf ball, namely the golf ball 182, from the tee shot 146 on the tee 148. As a typical casual golfer, the golfer 142 hits the golf ball 100 and the golf ball 182 at a head speed of less than 100 miles per hour. FIG. 1 illustrates a comparison between the trajectory 150 of the golf ball 100 and the trajectory 180 of the golf ball 182 after each golf ball is hit by the driver 144. Each golf ball has a similar trajectory length since each golf ball has a similar initial velocity associated with a shot 144 hitting a head speed of less than 100 mph. After the driver 144 hits the ball below the 100 mph head speed, since the golf ball 100 has an initial velocity similar to the golf ball 182, the trajectory 150 extends approximately the same length as the trajectory 180.

在圖2中，職業高爾夫球手152使用長擊桿144從發球台148上的開球球座146擊打高爾夫球100和另一種類型的高爾夫球，即高爾夫球182。作為典型的職業高爾夫球手，高爾夫球手152以桿頭速度高於125英里/小時擊打高爾夫球100和高爾夫球182。圖2說明各高爾夫球被長擊桿144擊球後，高爾夫球100的軌跡160和高爾夫球182的軌跡162之間的對比。由於高爾夫球100和高爾夫球182各自具有與高於125英里/小時桿頭速度的長擊桿擊球有關的不同的初速度，軌跡160長於軌跡162。當以高於125英里/小時桿頭速度的長擊桿144擊球時，高爾夫球100具有高於高爾夫球182的初速度，進而，高爾夫球100比高爾夫球182飛得更遠。In FIG. 2, professional golfer 152 uses golfer 144 to strike golf ball 100 and another type of golf ball, namely golf ball 182, from tee court 146 on tee 148. As a typical professional golfer, the golfer 152 hits the golf ball 100 and the golf ball 182 at a head speed of more than 125 miles per hour. 2 illustrates the contrast between the trajectory 160 of the golf ball 100 and the trajectory 162 of the golf ball 182 after each golf ball is hit by the driver 144. Since the golf ball 100 and the golf ball 182 each have different initial velocities associated with a bat shot above 125 mph, the trajectory 160 is longer than the trajectory 162. When the ball is hit with a long stick 144 that is above the 125 mph head speed, the golf ball 100 has an initial velocity higher than the golf ball 182, and thus, the golf ball 100 flies farther than the golf ball 182.

表3-6展示了對測試球執行的測試的結果，其中包括根據本發明製備的高爾夫球以及目前市場上出售的現有高爾夫球。根據本發明製備的高爾夫球包括實施例1，其細節在表1中展示。材料A、B、C和D參照表8-11進行更詳細的論述。目前市場上出售的現有高爾夫球包括比較例1-4，其細節在表2中展示(其中PBR是聚丁二烯橡膠)。表3-6中展示的結果包括初速度(IV)。所有IV的結果具有±1英里/小時的不確定度。Tables 3-6 show the results of tests performed on test balls, including golf balls prepared in accordance with the present invention, as well as existing golf balls currently on the market. A golf ball prepared in accordance with the present invention includes Example 1, the details of which are shown in Table 1. Materials A, B, C, and D are discussed in more detail with reference to Tables 8-11. Existing golf balls currently on the market include Comparative Examples 1-4, the details of which are shown in Table 2 (wherein PBR is a polybutadiene rubber). The results shown in Tables 3-6 include the initial velocity (IV). All IV results have an uncertainty of ±1 mph.

對測試球執行的測試按照如下所述進行：耐克SQ Dymo長擊桿(桿面傾角：10.5°；桿身：Diamana，三菱麗陽(Mitsubishi Rayon)生產；桿身硬度：X(加硬)；握把：golf pride生產)被固定到Miyamae有限公司生產的揮桿機器人上，然後以約80英里/小時到約125英里/小時的不同桿頭速度揮桿。桿面朝向正對擊球方向。向前/向後調整開球球座的位置，以使開球球座位於向下揮桿球桿處於垂直時的點前方3英寸的位置。調節開球球座的高度以及球桿趾部-跟部(toe-heel)相對於開球球座的位置，以使擊球痕跡中心位於從趾部到跟部穿過桿面的中心。The test performed on the test ball was carried out as follows: Nike SQ Dymo driver (lap angle: 10.5°; shaft: Diamana, Mitsubishi Rayon); shaft hardness: X (hardened); The grip: golf pride production) is fixed to a swing robot produced by Miyamae Co., Ltd., and then swings at a different head speed of about 80 mph to about 125 mph. The face faces in the direction of the facing ball.
