Abstract

A golf ball having a sinusoidal surface is disclosed. The golf ball has a sinusoidal structure. The golf ball of the present invention conforms with the 1.68 inches diameter requirement for USGA approved golf balls. The interconnected sine waves form a sinusoidal structure in the preferred embodiment. The preferred embodiment has a parting line that alternates upward and downward along a sine wave.

Claims

1. A golf ball comprising a sinusoidal surface, the sinusoidal surface covering the entire golf ball, the sinusoidal surface defining an outersphere diameter of the golf ball of at least 1.68 inches.

2. The golf ball according to claim 1, wherein the golf ball has an innersphere diameter of between 1.662 inches and 1.666 inches.

3. The golf ball according to claim 1, wherein the sinusoidal surface includes a plurality of sine waves overlapping to define the sinusoidal surface, at least one of the plurality of sine waves having apices located on the outersphere.

4. The golf ball according to claim 3, wherein the width of each of the apices is in the range of 0.0001 inch to 0.001 inch.

5. The golf ball according to claim 3, wherein at least one of the sine waves has a frequency different from that of another sine wave.

6. The golf ball according to claim 1, wherein the sinusoidal surface is a helical sinusoidal surface.

7. A golf ball comprising:

a first hemisphere having a sinusoidal surface; and

a second hemisphere having a sinusoidal surface, the second hemisphere being coupled to the first hemisphere along a parting line, the golf ball having an outersphere diameter of at least 1.68 inches and an innersphere diameter of between 1.662 inches and 1.666 inches.

8. The golf ball according to claim 7, wherein the parting line has a sine wave configuration.

9. The golf ball according to claim 7, wherein each of the sinusoidal surfaces includes a plurality of sine waves overlapping to define the sinusoidal surface, at least one of the plurality of sine waves having apices located on the outersphere.

10. The golf ball according to claim 9, wherein the width of each of the apices is in the range of 0.0001 inch to 0.001 inch.

11. The golf ball according to claim 9, wherein at least one of the sine waves has a frequency different from that of another sine wave.

12. The golf ball according to claim 7, wherein each of the sinusoidal surfaces is a helical sinusoidal surface.
