GOLF BALL WITH CONTOURED DIMPLES

摘要

A new configuration for dimples (4) on the surface of a gold ball (2) is characterized by at least a portion of the bottom surface of the dimple (4) having a raised contour which is still below the surface of the ball (2). The contoured portion may comprise many shapes including of a crescent (2, 3) or a sinusoidal (4, 5) configuration. Moreover, the contoured portion may have different portions having different depths. The contours within at least some of the dimples (4) on the surface of the ball (2) alter the air flow across the golf ball (2) surface to reduce drag and increase the distance the ball (2) will travel.
