Abstract
Embodiments of shaft plugs for golf clubs and methods to manufacture golf clubs with shaft plugs are generally described herein. Other embodiments of shaft plugs may be described and claimed.
Claims22
A shaft plug comprising:
- an axial shaft member defining a proximal end and a distal end along a longitudinal axis defined by the axial shaft member;
- a sealing member formed at the distal end of the axial shaft member and extending outwardly at a substantially perpendicular angle relative to the longitudinal axis;
- and
- at least one internal member extending outwardly along the axial shaft member at a substantially perpendicular angle relative to the longitudinal axis of the axial shaft member, wherein the at least one internal member is deformable.

A golf club comprising:
- a club shaft defining an elongated shaft body having a distal portion and a proximal portion, wherein the club shaft defines a shaft lumen in communication with a lumen opening formed at an end of the distal portion of the elongated shaft body;
- a hosel sleeve engaged to the distal portion of the club shaft, wherein the hosel sleeve defines a sleeve recess configured to receive the distal portion of the elongated shaft body;
- and
- a shaft plug configured to engage the shaft lumen of the club shaft, the shaft plug comprising:
- an axial shaft member defining a proximal end and a distal end along a longitudinal axis defined by the axial shaft member;
- a sealing member formed at the distal end of the axial shaft member and extending outwardly at a substantially perpendicular angle relative to the longitudinal axis;
- and
- at least one internal member extending outwardly along the axial shaft member at a substantially perpendicular angle relative to the longitudinal axis of the axial shaft member, wherein the at least one internal member is deformable.

A method to manufacture a golf club comprising:
- forming club shaft defining a distal portion and a proximal portion, wherein the club shaft defines a shaft lumen in communication with a lumen opening formed at an end of the distal portion;
- forming a hosel sleeve engaged to the distal portion of the club shaft, wherein the hosel sleeve defines a sleeve recess configured to receive the distal portion of the club shaft;
- and
- forming a shaft plug comprising:
- an axial shaft member defining a proximal end and a distal end along a longitudinal axis defined by the axial shaft member;
- a sealing member formed at the distal end of the axial shaft member and extending outwardly at a substantially perpendicular angle relative to the longitudinal axis;
- and
- at least one internal member extending outwardly along the axial shaft member at a substantially perpendicular angle relative to the longitudinal axis of the axial shaft member, wherein the at least one internal member is deformable;
- engaging the shaft plug to the shaft lumen such that shaft plug substantially seals off the lumen opening;
- applying an epoxy to the distal portion of the club shaft;
- and
- engaging the distal portion of the club shaft within the hosel sleeve such that the epoxy is prevented from entering the shaft lumen.
