The present application claims priority to U.S. Provisional Patent Application No. 61/140,780, filed on Dec. 24, 2008.

Not Applicable

1. Field of the Invention

The present invention relates to a golf club. More specifically, the present invention relates to golf club training.

2. Description of the Related Art

The prior art discloses various training aids. One such example is U.S. Pat. No. 7,597,632 for Gold Putting Practice Aid which discloses an apparatus for guiding stroking movement of a putter, comprising a base frame engageable with and forming a border about a putting surface in an operative stroke practice position.

Another example is U.S. Pat. No. 7,572,192 issued to Boyd for Golf Swing Training Aid. This patent discloses the use of a “C”-shaped head rest that is positioned across the user's forehead and padded for comfort. The headrest is connected to an extendable shaft that varies in length from 4 feet long to 7 feet long. The headrest trains the golfer to maintain a proper head position during a golf swing.

Yet another example is U.S. Pat. No. 7,568,979 for Golf Swing Training Apparatus which discloses a mounting bar with an extendable length arm stabilizer extending outwardly from the mounting bar and terminating in a headrest.

Tolson, U.S. Pat. No. 7,429,222 for a Parallel Putting Device And Method discloses a putting aid using device to maintain the position of the putter during the putt.

Training an individual to golf is difficult. It is important to establish skill quickly and to reach a satisfactory level of performance. Equipment changes have improved many aspects of the game of golf, but the game is still difficult and requires goods skills to play well.

Many golfers are self taught or poorly taught and this limits the level of skill and satisfaction the golfer can achieve. Training is difficult due in part to the free constraints of golf swings, the large range of body motions required to achieve swings, combined with the importance of sequencing and timing of motions. Training aids are designed to provide reference and guidance to the golfer to experience components of the swings and the proper rate and sequence of these motions.

The present invention overcomes these difficulties. The present invention is a unique and improved training aid to assist the golfer in learning these skills. The purpose of the present invention is to slow the back swing to help with sequence and timing. The present invention does not slow the down swing.

Additionally, the present invention is used to assist in the proper rate and sequence of the closing of the club face to the golf ball via rotation of the club. This invention triggers a torque that coerces the rotation by a helping torque.

Having briefly described the present invention, the above and further objects, features and advantages thereof will be recognized by those skilled in the pertinent art from the following detailed description of the invention when taken in conjunction with the accompanying drawings.

FIG. 1 is a perspective view of the invention.

FIG. 1 a is a top plan view of the invention which is deployed when the golf club is in backswing.

FIG. 2 is a view of the invention.

FIG. 2 a is a top plan view of the invention while the golf club is in downswing or the golf club head is at address.

The present invention uses a self-deploying airbrake that is either symmetric with no torque, or anti-symmetric with preferential torque. A preferred embodiment includes both functions with the ability to control the combination.

The invention preferably includes semi-fins that form a semi-circle and are mounted conformably about the shaft as shown in FIG. 1 .

The present invention comprises golf club training aid 200 which comprises two deployable fins, 220 ( a - b ) connected to a hinge 250 . The hinge 250 is capable of attaching to a shaft 150 of a golf club 100 . The fins 220 ( a - b ) are deployable during a backswing and retractable during a downswing. The golf club 100 comprises a golf club head 20 with a crown component 22 , face component 24 , and ribbon section 26 .

The invention adds a minimal amount of mass to a golf club, and functions automatically. The training aid 200 retards force in the golfer's back swing, but allows full swing speed in the golfer's down swing. The training aid 200 is preferably applied to a golf club with an adhesive tape and is removable. The training aid 200 is preferably made of a thermoset polymer or thermoplastic material. Different lengths are used to vary the degree of drag and torque. Such lengths comprise a full shaft length, a half shaft length, a quarter shaft length, and a one-eighth shaft length. Subtle edge shapes 30 modify timing of the deployment.
