Abstract

Embodiments of golf club heads with aerodynamic features and related methods are described herein. Various embodiments of the golf club heads with aerodynamic features and related methods include a golf club head comprising a body. In many embodiments, the body comprises a strikeface, a heel region, a toe region opposite the heel region, a sole, a crown, a trailing edge between the sole and the crown, a back opposite the strikeface, and one or more cavities located at least at one of: the back and in the sole adjacent to the trailing edge; or the back and in the trailing edge. Other examples and related methods are also disclosed herein.

First claim

What is claimed is:

1 . A golf club head comprising:
a body comprising:
a strikeface;
a heel region;
a toe region opposite the heel region;
a sole;
a crown having an apex;
a trailing edge between the sole and the crown;
a back opposite the strikeface; and
one or more cavities located at least at one of:
the back and in the sole adjacent to the trailing edge; or
the back and in the trailing edge.

2 . The golf club head of claim 1 , wherein:
one cavity of the one or more cavities comprises a cavity depth of approximately 1.27 mm to 3.81 mm.

3 . The golf club head of claim 1 , wherein:
one cavity of the one or more cavities comprises a cavity depth of approximately 2.54 mm.

4 . The golf club head of claim 1 , wherein:
one cavity of the one or more cavities comprises a cavity depth of approximately 1.27 mm.

5 . The golf club head of claim 1 , further comprising a ratio of an apex position to a cavity depth;
wherein, the apex position is defined as an apex height multiplied by the difference between a distance from the apex to the back and a distance from the apex to the strikeface; and the ratio is greater than approximately 3.5 inches.

6 . The golf club head of claim 1 , wherein:
one cavity of the one or more cavities comprises a cavity width of approximately 4.45 cm to approximately 20.32 cm.

7 . The golf club head of claim 1 , wherein:
one cavity of the one or more cavities comprises a cavity height of approximately 4.826 mm to approximately 5.334 mm.

8 . The golf club head of claim 1 , wherein:
the one or more cavities comprise two or more cavities; and the two or more cavities are stacked.

9 . The golf club head of claim 1 , wherein:
the one or more cavities comprise two or more cavities; and the two or more cavities are adjacent to each other.

10 . The golf club head of claim 1 , wherein:
an inner profile shape of one of the one or more cavities is flat.

11 . The golf club head of claim 1 , wherein:
the body further comprises:
a weight-receiving cavity opening to an exterior sole surface and bounded by an exterior port top surface and one or more port side walls;
a sole weight is conformal with the weight-receiving cavity; and one of the one or more cavities is aligned with the weight-receiving cavity.

12 . A golf club comprising:
a shaft; a grip; and a golf club head comprising:
a body comprising:
a strikeface;
a heel region;
a toe region opposite the heel region;
a sole;
a crown having an apex;
a trailing edge between the sole and the crown;
a back opposite the strikeface; and
one or more cavities located at least at one of:
the back and in the sole adjacent to the trailing edge; or
the back and in the trailing edge.

13 . The golf club of claim 12 , further comprising a ratio of an apex position to a cavity depth; wherein,
the apex position is defined as an apex height multiplied by the difference between a distance from the apex to the back and a distance from the apex to the strikeface; and the ratio is greater than approximately 3.5 inches.

14 . The golf club of claim 12 , wherein:
the one or more cavities comprise two or more cavities; and the two or more cavities are stacked.

15 . The golf club of claim 12 , wherein:
the one or more cavities comprise two or more cavities; and the two or more cavities are adjacent to each other.

16 . The golf club of claim 12 , wherein:
an inner profile shape of one of the one or more cavities is flat.

17 . The golf club of claim 12 , wherein:
the body further comprises:
a weight-receiving cavity opening to an exterior sole surface and bounded by an exterior port top surface and one or more port side walls;
a sole weight is conformal with the weight-receiving cavity; and one of the one or more cavities is aligned with the weight-receiving cavity.

18 . A method for manufacturing a golf club head, comprising:
forming a body from a first material having a first density, the body comprising:
strikeface;
a heel region;
a toe region opposite the heel region;
a sole;
a crown having an apex;
a trailing edge between the sole and the crown;
a back opposite the strikeface; and
one or more cavities located at least at one of:
the back and in the sole adjacent to the trailing edge; or
the back and in the trailing edge;

forming a faceplate; and attaching the faceplate to the body.

19 . The method for manufacturing of claim 18 , further comprising a ratio of an apex position to a cavity depth; wherein,
the apex position is defined as an apex height multiplied by the difference between a distance from the apex to the back and a distance from the apex to the strikeface; and the ratio is greater than approximately 3.5 inches.

20 . The method for manufacturing of claim 18 , wherein:
the body further having:
a weight-receiving cavity opening to an exterior sole surface and bounded by an exterior port top surface and one or more port side walls;
a sole weight is conformal with the weight-receiving cavity; and one of the one or more cavities is aligned with the weight-receiving cavity.
