Abstract

A golf ball flight angle demonstration device includes a rigid body including integral first and second simulated golf club heads with bottom sole surfaces extending between heel and toe ends. A first club face is located on the first simulated golf club head on a plane set at a first loft angle. A second club face is provided on the second simulated golf club head on a plane set at a second loft angle that is greater than the first loft angle. The club faces are oriented in relation to one another such that the planes of the first and second faces intersect along a reference line substantially parallel to a line tangent either of the sole surfaces at a reference face centerline extending through either club face.

Claims

1. A golf ball flight angle demonstration device, comprising:

a rigid body having first and second club faces with different lofts and which are oriented in predetermined spaced, stacked relation, one to the other, the first club face having a given lie angle, and wherein the second club face has a lie angle which is substantially similar to the lie angle of the first club face, and wherein each club face has a hosel.

2. A golf ball flight angle demonstration device as claimed in claim 1, wherein each face is oriented in the same direction.

3. A golf ball flight angle demonstration device as claimed in claim 1, and wherein each hosel lies in substantially the same plane.

4. A golf ball flight angle demonstration device as claimed in claim 1, and wherein each face has a reference face centerline, and wherein each reference face centerline lies in substantially the same plane.

5. A golf ball flight angle demonstration device as claimed in claim 1, and wherein each club face has a sole surface, and wherein each club face has a reference line which is tangential to the sole of each club face, and perpendicular to the respective reference face centerlines, and wherein the individual reference lines are substantially parallel to each other.

6. A golf ball flight angle demonstration device, comprising:

a rigid body having first and second golf club heads which are affixed together in predetermined spaced stacked relation one to the other, each golf club head having a given different loft, and the club faces simultaneously oriented in the same direction, and wherein the respective first and second club faces have substantially similar lie angles, and a hosel is borne on one of the golf club heads.

7. A golf ball flight angle demonstration device as claimed in claim 6, wherein a hosel is borne on each golf club head.

8. A golf ball angle demonstration device as claimed in claim 7, and wherein each hosel lies in substantially in the same plane.

9. A golf ball flight angle demonstration device as claimed in claim 6, and wherein each club face has a reference face centerline, and wherein each reference face centerline lies in substantially the same plane.

10. A golf ball flight angle demonstration device as claimed in claim 9, wherein each club face has a sole surface, and wherein each club face has a reference line which is tangential to the sole of each club face, and perpendicular to the respective reference face centerlines, and wherein the individual reference lines are substantially parallel to each other.

11. A golf ball flight angle demonstration device, comprising:

a first golf club head having a face, a sole, a given loft, and lie angle, a hosel and a reference face centerline; and

a second golf club head made integral with the first golf club head, the second golf club head positioned in predetermined spaced relation relative to the first golf club head, and wherein the second golf club head has a face, a sole, and a reference face centerline, the face of the second golf club facing substantially in the same direction as the face of the first golf club head, and wherein the second golf club head has a loft which is different from the loft of the first golf club head, and wherein the reference face centerline of each of the golf club heads lie in substantially the same plane, and wherein each golf club head has a reference line which is tangential to the sole of each of the golf club heads, and perpendicular to the respective reference face centerlines, the individual reference lines being substantially parallel to each other.
