Abstract

A device is provided that indicates to a user when the user has properly shifted a sufficient amount of his or her downward force to the trail foot and thereafter to the lead foot during the course of a golf swing, thereby effecting an optimal golf swing.

Claims (27)

1. A golf swing force shift indicator comprising:

a top face, a bottom face, a front face positioned at a front end of said force shift indicator and a rear face positioned at a rear end of said force shift indicator, wherein said bottom face extends from said front end to said rear end of said force shift indicator;

a continuous unitary plane forming said top face and extending from said front end to said rear end of said force shift indicator, wherein said top face has a lead foot placement site with a longitudinal centerline positioned more proximal to said front end than to said rear end and a trail foot placement site with a longitudinal centerline positioned more proximal to said rear end than to said front end; and

a bottom front plane, a bottom central plane and a bottom rear plane forming said bottom face, wherein said bottom front, central and rear planes are sequentially positioned relative to one another in a series along the length of said bottom face, said bottom front plane has a different angular orientation relative to said bottom central plane, said bottom rear plane has a different angular orientation relative to said bottom central plane, said bottom central plane intersects said bottom front plane along a forward pivot axis and said bottom central plane intersects said bottom rear plane along a rearward pivot axis.

2. The golf swing force shift indicator of claim 1 , wherein said bottom central plane is parallel to said top face.

3. The golf swing force shift indicator of claim 2 , wherein said angular orientation of said bottom front plane defines a forward angle of incline that is upward relative to said bottom central plane.

4. The golf swing force shift indicator of claim 3 , wherein said forward angle of incline is less than 30°.

5. The golf swing force shift indicator of claim 2 , wherein said angular orientation of said bottom rear plane defines a rearward angle of incline that is upward relative to said bottom central plane.

6. The golf swing force shift indicator of claim 5 , wherein said rearward angle of incline is less than 30°.

7. The golf swing force shift indicator of claim 1 , wherein a longitudinal distance between said forward pivot axis and said longitudinal centerline of said lead foot placement site defines a forward leverage distance, a longitudinal distance between said rearward pivot axis and said longitudinal centerline of said trail foot placement site defines a rearward leverage distance and said rearward leverage distance is greater than said forward leverage distance.

8. The golf swing force shift indicator of claim 1 further comprising two or more forward projections extending downwardly from said forward pivot axis.

9. The golf swing force shift indicator of claim 1 further comprising two or more rearward projections extending downwardly from said rearward pivot axis.

10. A golf swing force shift indicator comprising:

a top face, a bottom face, a front face positioned at a front end of said force shift indicator and a rear face positioned at a rear end of said force shift indicator, wherein said bottom face extends from said front end to said rear end of said force shift indicator;

a continuous unitary plane forming said top face and extending from said front end to said rear end of said force shift indicator, wherein said top face has a lead foot placement site with a longitudinal centerline positioned more proximal to said front end than to said rear end and a trail foot placement site with a longitudinal centerline positioned more proximal to said rear end than to said front end; and

a bottom front plane, a bottom central plane and a bottom rear plane forming said bottom face, wherein said bottom front, central and rear planes are sequentially positioned relative to one another in a series along the length of said bottom face, said bottom front plane has an upward angular orientation relative to said bottom central plane defining a forward angle of incline, said bottom rear plane has an upward angular orientation relative to said bottom central plane defining a rearward angle of incline, said bottom central plane intersects said bottom front plane along a forward pivot axis and said bottom central plane intersects said bottom rear plane along a rearward pivot axis.

11. The golf swing force shift indicator of claim 10 , wherein a longitudinal distance between said forward pivot axis and said longitudinal centerline of said lead foot placement site defines a forward leverage distance, a longitudinal distance between said rearward pivot axis and said longitudinal centerline of said trail foot placement site defines a rearward leverage distance and said rearward leverage distance is greater than said forward leverage distance.

12. The golf swing force shift indicator of claim 10 , wherein said bottom central plane is parallel to said top face.

13. The golf swing force shift indicator of claim 10 , wherein said forward angle of incline is less than 30°.

14. The golf swing force shift indicator of claim 10 , wherein said forward angle of incline is less than 30°.

15. The golf swing force shift indicator of claim 10 further comprising two or more forward projections extending downwardly from said forward pivot axis.

16. The golf swing force shift indicator of claim 10 further comprising two or more rearward projections extending downwardly from said rearward pivot axis.

17. A golf swing force shift indicator comprising:

a top face, a bottom face, a front face positioned at a front end of said force shift indicator and a rear face positioned at a rear end of said force shift indicator, wherein said bottom face extends from said front end to said rear end of said force shift indicator;

a continuous unitary plane forming said top face and extending from said front end to said rear end of said force shift indicator, wherein said top face has a lead foot placement site with a longitudinal centerline positioned more proximal to said front end than to said rear end, a trail foot placement site with a longitudinal centerline positioned more proximal to said rear end than to said front end; and

a bottom front plane, a bottom central plane and a bottom rear plane forming said bottom face, wherein said bottom front, central and rear planes are sequentially positioned relative to one another in a series along the length of said bottom face, said bottom front plane has an upward angular orientation relative to said bottom central plane defining a forward angle of incline, said bottom rear plane has an upward angular orientation relative to said bottom central plane defining a rearward angle of incline, said bottom central plane intersects said bottom front plane along a forward pivot axis and said bottom central plane intersects said bottom rear plane along a rearward pivot axis, a longitudinal distance between said forward pivot axis and said longitudinal centerline of said lead foot placement site defines a forward leverage distance, a longitudinal distance between said rearward pivot axis and said longitudinal centerline of said trail foot placement site defines a rearward leverage distance and said rearward leverage distance is greater than said forward leverage distance.

18. The golf swing force shift indicator of claim 17 , wherein said bottom central plane is parallel to said top face.
