Abstract

A golf club fitting apparatus for helping with golf club alignment is provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. A leveler body is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.

Claims (37)

1 . A golf club fitting apparatus for attaching to a golf club, said golf club including a shaft defining a shaft axis, a golf club head connected to a first end of said shaft, and a grip connected to a second end of said shaft opposite said first end, said golf club fitting apparatus comprising:

a mounting portion configured to attach to said shaft of said golf club; and

a leveler body connected to said mounting portion,

wherein said leveler body is configured to be in a fixed position relative to said shaft,

wherein said leveler body includes a level indicator visible to a user when standing at an address position,

wherein said level indicator indicates an orientation of said leveler body relative to a ground plane,

wherein said mounting portion comprises a shaft engaging portion and an adjustment portion,

wherein said adjustment portion is pivotable with respect to said shaft engaging portion,

wherein said leveler body is connected to said adjustment portion,

wherein said leveler body is rotatable with respect to said adjustment portion,

wherein said leveler body includes markings on a top surface to indicate a target position for said level indicator,

position indicators on said shaft engaging portion, said adjustment portion, and said leveler body,

wherein a first set of said position indicators indicate a relative position between said shaft engaging portion and said adjustment portion,

wherein a second set of said position indicators indicate a relative position between said adjustment portion and said leveler body.

2 . The golf club fitting apparatus of claim 1 , wherein said adjustment portion is connected to said shaft engaging portion by a fastener, and

wherein said leveler body is connected to said adjustment portion by a rod.

3 . The golf club fitting apparatus of claim 1 , wherein said mounting portion includes an opening configured to receive said shaft of said golf club, and

wherein said mounting portion includes a fastener to secure said mounting portion to said shaft of said golf club.

4 . The golf club fitting apparatus of claim 3 , wherein said opening of said mounting portion includes an angled wall configured to abut said shaft in an installed configuration.

5 . A golf club fitting apparatus comprising:

a mounting portion having an opening for receiving a shaft; and

a leveler body connected to said mounting portion,

wherein said mounting portion comprises a shaft engaging portion and an adjustment portion, said adjustment portion being pivotable with respect to said shaft engaging portion, and

wherein said leveler body includes a level indicator visible to a user when standing at an address position,

wherein said level indicator indicates an orientation of said leveler body relative to a ground plane,

wherein said leveler body is rotatable with respect to said adjustment portion,

position indicators on said shaft engaging portion, said adjustment portion, and said leveler body,

wherein a first set of said position indicators indicate a relative position between said shaft engaging portion and said adjustment portion, and

wherein a second set of said position indicators indicate a relative position between said adjustment portion and said leveler body.

6 . The golf club fitting apparatus of claim 5 , wherein said adjustment portion is connected to said shaft engaging portion by a fastener, and

wherein said leveler body is connected to said adjustment portion by a rod.

7 . The golf club fitting apparatus of claim 5 , wherein said mounting portion includes a fastener to secure said mounting portion to said shaft.

8 . The golf club fitting apparatus of claim 5 , wherein said level indicator is a bubble.

9 . The golf club fitting apparatus of claim 5 , wherein said level indicator is a ball.

10 . The golf club fitting apparatus of claim 5 , wherein said leveler body includes markings to indicate a target position of said level indicator.

11 . The golf club fitting apparatus of claim 10 , wherein said markings comprise a first axis and a second axis, said second axis being perpendicular to said first axis; or

wherein said markings comprise a plurality of concentric circles.
