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, wherein the golf ball includes a first hemisphere and a second hemisphere, the first and second hemispheres being connected together along a parting line, the parting line having a sine wave configuration.

2. The golf ball according to claim 1, wherein the sinusoidal surface includes a plurality of sine waves overlapping to define the sinusoidal surface.

3. The golf ball according to claim 2, wherein at least one of the sine waves has a frequency different from that of another sine wave.

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

5. 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 parting line having a sine wave configuration,

wherein the golf ball has an outersphere diameter of at least 1.68 inches.

6. The golf ball according to claim 5, wherein each of the sinusoidal surfaces includes a plurality of sine waves overlapping to define the sinusoidal surface.

7. The golf ball according to claim 6, wherein at least one of the sine waves has a frequency different from that of another sine wave.

8. The golf ball according to claim 5, wherein each of the sinusoidal surfaces is a helical sinusoidal surface.
