Abstract
A golf ball includes a multiplicity of dimples on its outer surface. At least one or more of the multiplicity of dimples are each configured to have a convex bottom portion formed by a circular-arc defined by a center positioned inside the ball and a curvature radius “r” mm smaller than a radius “R” mm of the ball but larger than a value (R−0.5) mm. The golf ball specified such that the shapes of the dimples are optimized as described above exhibits high flight characteristics.
Claims12
A golf ball comprising a multiplicity of dimples on its outer surface, wherein at least one or more of said multiplicity of dimples are each configured to have a convex bottom portion formed by a circular-arc defined by a curvature radius “r” mm whose center is positioned inside said ball and the radius “r” mm of the convex bottom of the dimple and a radius “R” mm of said ball satisfy the following relationship:
- R>r>R−0.5.
A golf ball comprising a multiplicity of dimples on its outer surface, wherein at least one or more of said multiplicity of dimples are each configured to have a convex bottom portion formed by a circular-arc defined by a center positioned inside said ball and a curvature radius “r” mm smaller than a radius “R” mm of said ball but larger than a value (R−0.5) mm, wherein said dimple having said convex bottom portion is formed into a non-circular shape in a plan view.
