CA 2317429

A golf ball (2) having improved aerodynamic efficiency is characterized by the arrangement of a pluraliy of modified tear-drop shaped dimples (10, 20) arranged on the surface thereof. The ball has a dimple-free equator (E) which divides the ball into two identical hemispheres, each of which is broken into equal quadrants by two great circles (4, 6) passing through the poles (P) of the ball (2). Each quadrant has a maximum circular area (8) filled with a first plurality of non-symmetric, teardrop shaped dimples (10). A second plurality of non-symmetric, teardrop shaped dimples (20) is arranged between the circular areas (8), so that the dimple coverage on the ball (2) is maximized.

Cette invention concerne une balle de golf (2) qui possède une meilleure efficacité aérodynamique et qui se caractérise, à sa surface, par la disposition de plusieurs renfoncements (10, 20) modifiés et en forme de gouttes d'eau. Cette balle possède un équateur (E) sans renfoncements qui la divise en deux hémisphères identiques, chaque hémisphère étant divisée en quadrants égaux par deux grands cercles (4, 6) qui passent par les pôles (P) de la balle (2). Chaque quadrant possède une zone circulaire maximale (8) remplie de plusieurs renfoncements en forme de gouttes d'eau, non symétriques et d'un premier type (10). Plusieurs renfoncements en forme de gouttes d'eau, non symétriques et d'un second type (20) sont disposés entre les zones circulaires (8) de manière à maximiser la couverture de la balle (2) par lesdits renfoncements.
