Abstract
Description
(Vd − Vc) / Vc ≦ 2.15
Rv = (Vd − Vc) / Vc
この数式において、Vcは全ての中央部16の容積の合計を表し、Vdはディンプル10の容積の合計を表す。中央部16の容積は、ディンプル10の表面とジョイントラインJLを含む平面とに囲まれた空間の容積である。ディンプル10の容積は、ディンプル10の表面と仮想球14の表面とに囲まれた空間の容積である。比Rvは、2.15以下が好ましい。換言すれば、ゴルフボール2が下記数式を満たすことが好ましい。
(Vd − Vc) / Vc ≦ 2.15
P = (N1 / N) * 100
この数式において、N1は中央部16の輪郭が円形であり縁部18の輪郭が非円形であるディンプル10の数であり、Nはディンプル10の総数である。
100質量部のハイシスポリブタジエン(JSR社の商品名「BR−730」)、22.5質量部のアクリル酸亜鉛、5質量部の酸化亜鉛、5質量部の硫酸バリウム、0.5質量部のジフェニルジスルフィド及び0.6質量部のジクミルパーオキサイドを混練し、ゴム組成物を得た。このゴム組成物を共に半球状キャビティを備えた上型及び下型からなる金型に投入し、170℃で18分間加熱して、直径が38.5mmであるコアを得た。
ファイナル金型を変更し、ディンプルの仕様を下記の表1−4に示される通りとした他は実施例1と同様にして、実施例2−13及び比較例1のゴルフボールを得た。
ファイナル金型を変更し、ディンプルの仕様を下記の表4に示される通りとした他は実施例1と同様にして、比較例1のゴルフボールを得た。このゴルフボールのディンプルは、ほぼ碗状である。
ゴルフラボラトリー社のスイングマシンに、アイアン型クラブ#7(住友ゴム工業社の商品名「XXIO−10」、シャフト硬度:R)を装着した。このゴルフボールを、ヘッド速度が33m/secである条件で打撃して、発射地点から静止地点までの距離を測定した。テスト時は、ほぼ無風であった。20回の測定で得られたデータの平均値が、下記の表1−4に示されている。

Claims (3)
- その表面に複数のディンプルを備えたゴルフボールであって、
それぞれのディンプルが、碗状の中央部と、この中央部と滑らかに連続するリング状の縁部とを有しており、
