Abstract
A small fin extends radially aft from a golf club head to resist rotation of a golf club shaft about its longitudinal axis. The fin is aligned relative to the club head so as to produce minimum drag when the club is drawn smoothly through the desired arc without rotating the club shaft about its longitudinal axis. Rotation of the shaft about its longitudinal axis displaces the fin from its minimum drag position and hence puts the fin in disequilibrium, such that the drag is greater on the side of the fin that would urge the fin back into its equilibrium position, thereby rotating the shaft back into its correct position.
Claims12
An apparatus, comprising:
- a) a first drag member and a second drag member oblique to the first drag member;
- and
- b) a coupler adapted to connect the first and second drag members to a golf club having a club head such that the first and second drag members extend substantially aft of the club head, whereby the first and second drag members act to apply a force to the club head during a swing to urge the club back toward a predetermined path wherein said apparatus has only two drag members.
An apparatus, comprising:
- a) a club head connected to the head end of a shaft;
- b) a first drag member extending substantially aft of the club head;
- and
- c) a second drag member oblique to the first drag member, such that the second drag member extends substantially aft of the club head, whereby the first and second drag members act to apply a force to the club head during a swing to urge the club back toward a predetermined path wherein said apparatus has only two drag members.
A method, comprising:
- a) aligning a first drag member and a second drag member oblique to the first drag member, substantially aft of a golf club head, such that when the club is swung through a predetermined path drag forces on the first and second drag members are in equilibrium, but when the club is swung through a path other than the predetermined path drag forces on the first and second drag members are in disequilibrium and urge the club back toward the predetermined path wherein there are only two drag members.
