Patent

CA 2393566

A golf ball (2) having improved aerodynamic efficiency is characterized by the arrangement of a plurality of modified tear drop shaped dimples 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 portions by a plurality of great circles (104, 106, 108, 110) passing through the poles (P) of the ball. Each portion has a maximum circular area (112) filled with a first plurality of non-circular dimples (10). A second plurality of non-circular dimples (10) is arranged between the circular areas (112) so that the dimple coverage on the ball is maximized.

Cette invention concerne une balle de golf (2) à l'efficacité aérodynamique accrue caractérisée par une pluralité d'alvéoles en forme de goutte d'eau disposées sur sa surface. La balle comporte un équateur (E) sans alvéoles qui la divise en deux hémisphères égaux, chacun de ces hémisphères étant subdivisé en quartiers égaux par une pluralité de grands cercles (104, 106, 108, 110) passant par les pôles (P) de ladite balle. Chaque quartier renferme une zone circulaire maximum (112) contenant une première pluralité d'alvéoles non circulaires (10). Une seconde pluralité d'alvéoles non circulaires (10) est disposée entre les zones circulaires (112), ce qui a pour effet de maximiser la densité des alvéoles sur la balle.
