Abstract

The presently disclosed technology is directed to a modular golf club. In particular, the modular golf club includes at least one interchangeable sole component to allow adjustability of various characteristics of the modular golf club.

First claim

We claim:

1 . A modular golf club head, comprising:
a body portion comprising:
a face; and
a back extending rearward from at least a first portion of the face; and
at least one interchangeable sole to fit with the back, wherein the at least one interchangeable sole comprises:
a removably couplable intermediate sole piece to fit with at least a second portion of the back, wherein the removably couplable intermediate sole piece is removably couplable to the back; and
a removably couplable rear sole piece to fit with the removably couplable intermediate sole piece, wherein the removably couplable rear sole piece is removably couplable to the removably couplable intermediate sole piece and the back.

2 . The modular golf club head of claim 1 , wherein the back comprises:
a threaded bore to receive a fastener;
wherein the removably couplable intermediate sole piece comprises:
an intermediate sole through bore to receive the fastener to removably couple the removably couplable rear sole piece to the removably couplable intermediate sole piece and the back; and

wherein the removably couplable rear sole piece comprises:
a sole through bore to receive the fastener to removably couple the removably couplable rear sole piece to the removably couplable intermediate sole piece and the back.

3 . The modular golf club head of claim 1 , wherein the removably couplable intermediate sole piece further comprises an intermediate through bore to receive an intermediate fastener to removably couple the removably couplable intermediate sole piece to the back.

4 . The modular golf club head of claim 1 , wherein the back further comprises:
a bore to receive an alignment pin,
wherein the removably couplable intermediate sole piece further comprises:
the alignment pin to help secure the removably couplable intermediate sole piece to the back via the bore; and
a slot to receive a securing element; and

wherein the removably couplable rear sole piece further comprises:
the securing element to help secure the removably couplable rear sole piece to the removably couplable intermediate sole piece via the slot.

5 . The modular golf club head of claim 1 , wherein the back further comprises:
a body recess to receive an adjustable weight, wherein a heel-to-toe body recess length is longer than a heel-to-toe weight length of the adjustable weight;
wherein the removably couplable intermediate sole piece further comprises:
an intermediate cut-out extending from a front through to a back of the removably couplable intermediate sole piece to receive the adjustable weight, wherein a heel-to-toe cut-out length is at least the heel-to-toe body recess length; and

wherein the removably couplable rear sole piece further comprises:
a sole recess on a front of the removably couplable rear sole piece to receive the adjustable weight, wherein a heel-to-toe sole recess length is at least the heel-to-toe body recess length.

6 . The modular golf club head of claim 5 , wherein coupling the at least one interchangeable sole to the body portion secures the adjustable weight into a fixed position.

7 . The modular golf club head of claim 5 , wherein the removably couplable rear sole piece further comprises an indicator to indicate a position of the adjustable weight along the modular golf club head.

8 . The modular golf club head of claim 1 , wherein the at least one interchangeable sole comprises a first material and a second material, wherein the first material is denser than the second material.

9 . The modular golf club head of claim 8 , wherein the first material is located substantially face-ward and a second material is located substantially rearward causing the modular golf club head to be weight-biased toward the face or vice versa.

10 . The modular golf club head of claim 8 , wherein the first material is located substantially heel-ward and a second material is located substantially toe-ward causing the modular golf club head to be weight-biased toward a heel or vice versa.

11 . The modular golf club head of claim 1 , wherein coupling the at least one interchangeable sole to the body portion causes the modular golf club head to comprise one of an f grind, an s grind, an m grind, a d grind, an l grind, and a k grind.

12 . The modular golf club head of claim 1 , wherein coupling the at least one interchangeable sole to the body portion causes the modular golf club head to comprise a bounce angle between about 2° and about 20°.

13 . A modular golf club head, comprising:
a body portion comprising:
a face; and
a back extending rearward from at least a first portion of the face, wherein the back comprises:
a body recess to receive an adjustable weight, wherein a heel-to-toe body recess length is longer than a heel-to-toe weight length of the adjustable weight; and

at least one interchangeable sole to fit with the body portion, wherein the at least one interchangeable sole comprises:
a recess on a front of the at least one interchangeable sole to receive the adjustable weight, wherein a heel-to-toe recess length is at least the heel-to-toe body recess length.

14 . The modular golf club head of claim 13 , wherein the back further comprises:
a threaded bore to receive a fastener; and wherein the at least one interchangeable sole comprises a through bore to receive the fastener to removably couple the at least one interchangeable sole to the back.

15 . The modular golf club head of claim 13 , wherein the at least one interchangeable sole comprises:
a removably couplable intermediate sole piece to fit with the back, wherein the removably couplable intermediate sole piece is removably couplable to the back, and wherein the removably couplable intermediate sole piece further comprises:
an intermediate cut-out extending from a front through to a back of the removably couplable intermediate sole piece to receive the adjustable weight, wherein a heel-to-toe cut-out length is at least the heel-to-toe recess length; and
a removably couplable rear sole piece to fit with the removably couplable intermediate sole piece, wherein the removably couplable rear sole piece is removably couplable to the removably couplable intermediate sole piece and the back, wherein the removably couplable rear sole piece further comprises:
a sole recess on a front of the removably couplable rear sole piece to receive the adjustable weight, wherein a heel-to-toe sole recess length is at least the heel-to-toe body recess length; and
wherein the recess comprises:
the intermediate cut-out; and
the sole recess.

16 . The modular golf club head of claim 15 , wherein the back comprises:
a threaded bore to receive a fastener;
wherein the at least one interchangeable sole comprises:
a through bore to receive the fastener to removably couple the at least one interchangeable sole to the back;

wherein the removably couplable intermediate sole piece comprises:
an intermediate sole through bore to receive the fastener to removably couple the removably couplable rear sole piece to the removably couplable intermediate sole piece and the back; and

wherein the removably couplable rear sole piece comprises:
a sole through bore to receive the fastener to removably couple the removably couplable rear sole piece to the removably couplable intermediate sole piece and the back.

17 . A modular golf club head, comprising:
a body portion comprising:
a face; and
a back extending rearward from at least a first portion of the f
