Abstract
Description
- The present invention specifically relates to improving the configurations of dimples and lands on the surface of a sphere of a golf ball.
- Conventionally, a golf ball has plurality of dimples arranged on the surface of a golf ball to increase the aerodynamic property (lift/drag) by reducing the drag and increasing the lift. For example, making the surface shape of dimples non-circular such as elliptical (
Patent Document 1, 4), making dual dimples by providing convex portions or concave portions in dimples (Patent Document 2), and the configuration of connecting the dimples with grooves, and such (Patent Document 3, 5) have been proposed. -

2000-317014 - The problem to be solved by the present invention is to provide a golf ball with improved flight distance due to improvement in aerodynamic properties by means of contriving dimple designs.
- In order to solve the problem described above, the present invention adopted a golf ball in which the surface of a sphere is composed of dimples and lands excluding dimples, wherein said dimples are formed by elliptical dimples together with circular dimples, wherein one said elliptical dimple overlaps said circular dimples at both end parts in its major axis direction, respectively, said circular dimples and said elliptical dimples are connected with each other, and one said land is formed between three said elliptical dimples.
- Therefore, differently to the conventional golf ball with circular dimples formed, this golf ball has elliptical dimples together with circular dimples, and further has the composition wherein elliptical dimples overlap circular dimples, and elliptical dimples and circular dimples are connected with each other. Thus, increase in the amount of spin is restrained and the aerodynamic property (lift/drag) is increased, resulting in improving the flight distance.

- In
FIG.1 andFIG.2 , 100 is a golf ball and its surface of asphere 101 is composed ofdimples 102 andlands 103 excludingdimples 102, wherein saiddimples 102 are formed byelliptical dimples 104 together withcircular dimples 105. - As for
dimples 102, one said elliptical dimple 104 overlaps saidcircular dimples 105 at both end parts in itsmajor axis direction circular dimples 105 and saidelliptical dimples 104 are connected with each other. - Meanwhile, as for said
land 103, oneland 103 is formed between three saidelliptical dimples land 103 is surrounded by the peripheral edges ofelliptical dimples elliptical dimples - Therefore, differently to the conventional golf ball with circular dimples formed, this
golf ball 100 is a golf ball with said dimples and said land formed repeatedly in a definite relation, haselliptical dimples 105 together withcircular dimples 104, and further has the composition whereinelliptical dimples 104 overlapcircular dimples 105, andelliptical dimples 104 andcircular dimples 105 are connected with each other. Thus, increase in the amount of spin when thisgolf ball 100 is struck is restrained and the aerodynamic property (lift/drag) is increased. - Further,
FIG.3 andFIG.4 show a golf ball which differs in the point havingcircular dimples 115 formed in a conical shape with a hexagonal surface as an alternative to saidcircular dimples 105. Moreover,FIG.5 andFIG.6 showcircular dimples 125 in which the tip portion of theland 103 is cut diagonally 107 as an alternative to saidcircular dimples 105. - And now, the maximum depth of the overlapping portion of said circular dimples and said elliptical dimples is preferably 0.1 to 0.15 mm, the maximum depth of the central portion of said circular dimples is preferably 0.23 to 0.28 mm, and the maximum depth of the central portion of said elliptical dimples is preferably 0.33 to 0.38 mm.
- Differently to the conventional golf ball with circular dimples formed, both of these golf balls have elliptical dimples together with circular dimples, and further have the composition wherein elliptical dimples overlap circular dimples, and elliptical dimples and circular dimples are connected with each other. Thus, increase in the amount of spin is restrained and the aerodynamic property (lift/drag) is increased, resulting in improving the flight distance.
- The golf ball of the present invention may be used by golfers of from beginners to professionals.
