Abstract
A golf ball according to an aspect of the present invention is a golf ball having a large number of dimples, a surface of the golf ball is covered with a plurality of virtual flat surfaces each having a triangular shape, one or more dimples are arranged so as to correspond to each of the virtual flat surfaces, and an edge of each dimple is formed in a linear shape. Each dimple may have a triangular pyramid shape or a triangular frustum shape.
Claims12
A golf ball having a large number of dimples, wherein
- a surface of the golf ball has a plurality of edges forming a plurality of triangular shapes, the plurality of triangular shapes being planar with each other,
- a plurality of dimples are arranged so as to correspond to a respective each of the plurality of the edges, and
- the each of the plurality of the edges of the plurality of dimples is straight, and is not contoured along a spherical shape of the ball.
A golf ball having a large number of dimples, wherein
- a surface of the golf ball has a plurality of edges forming a plurality of triangular shapes, the plurality of triangular shapes being planar with each other,
- a plurality of dimples are arranged so as to correspond to a respective each of the plurality of the edges,
- the each of the plurality of the edges of the plurality of dimples is straight,
- the plurality of the edges are faces of a geodesic polyhedron inscribed in a phantom sphere of the golf ball, the phantom sphere being a sphere in which the golf ball is inscribed, and
- the sides of a triangle formed by edges of two dimples coincide with a contour of a face of a geodesic 180-faced polyhedron inscribed in the phantom sphere of the golf ball.
