1. Field of Invention

The present invention is related to sport swing mechanics and more particularly, a golf swing training apparatus.

2. Description of Related Art

Generally, golf enthusiasts, both amateur and professional, seek to hit the ball farther to improve their golf game and lower their golf game score. Golf teachers and analysts are continually giving their opinions on how to hit the ball farther by performing a proper golf swing and how to properly execute a preferred golf swing. However, even “experts” cannot agree on a simple method and explanation for correctly swinging a golf club.

Over the years, to achieve greater distance and accuracy, the golf swing has changed from one that relies more on the swinging of the arms and hands around the body, to one that relies more on the rotation of the body to leverage and accelerate the arms and hands.

DETAILED DESCRIPTION OF EMBODIMENTS

The following description provides detail of various embodiments of the invention, one or more examples of which are set forth below. Each of these embodiments are provided by way of explanation of the invention, and not intended to be a limitation of the invention. Further, those skilled in the art will appreciate that various modifications and variations may be made in the present invention without departing from the scope or spirit of the invention. By way of example, those skilled in the art will recognize that features illustrated or described as part of one embodiment, may be used in another embodiment to yield a still further embodiment. Thus, it is intended that the present invention also cover such modifications and variations that come within the scope of the appended claims and their equivalents.

Although the present invention is described in the context of a golf swing trainer, the present invention is also applicable to other types of sports swings including, but not limited to baseball, softball, and tennis.

The training apparatus 10 includes an alignment member or indicator rod 16 that provides instant feedback to alignment and target line as well as arm position relative to the body as the body rotates. Many sports require a rotational movement of the body to apply an approximately linear force to an object. For example, a discus or ball is preferably thrown in a generally straight line by first rotating the arms about the body to deliver a linear force to the ball or discus. Likewise, a golfer rotates the arms and golf club about the body to deliver an approximately linear force to a ball when the golf club head strikes the ball.

Generally, the faster the golfer swings the golf club, the greater the force that is transferred to the golf ball. Synchronization of the arms to the upper body as the body rotates delivers both speed and consistency of impact. Conversely, if the arms are unsynchronized relative to the upper body, for example, the arms moving across the body instead of staying in front of the upper body, the more separated the arms and upper body become, resulting in less speed and power. An increase in the rotation of the hands and arms alone cannot make up for the speed loss caused by not using the body properly.

The golf swing training device 10 is designed to visually communicate the positions required to make a consistent and powerful swing as well as communicate the feel of a properly connected swing where the arms and body are synchronized to deliver maximum speed and consistency. The various positions of the indicator rod 16 throughout the swing enables a golfer, while swinging, to determine whether the body is rotating properly thereby enabling its user to make immediate adjustment.

For example, when executing a full golf swing (for right-handed golfers), when the user positions the golf club head adjacent the golf ball, it is desirable for a left end of the indicator rod 16 to point up but parallel to the target line. As the golfer rotates the golf club up and away from the golf ball, the left side of the indicator rod 16 preferably rotates to the right, and arrives at a position at the top or completion of the backswing that is at least 90-degrees from the target line (the preferred line or path of ball travel) while the longitudinal axis of the indicator rod 16 is preferable parallel to the ground.

As the user begins a downswing of the golf club, the left end of the indicator rod 16 preferably begins to point slightly up as the right end of the indicator rods drops down. As the user continues the downswing, as the golf club head impacts the golf ball, the alignment member 16 should be in a position nearly identical to the position when the user positions the golf club head adjacent to the golf ball. As the user continues to rotate the club after impact, for example follow-through, the left end of the indicator rod 16 should rotate left horizontally as it moves up before inverting or exchanging relative positions with the right end of the indicator rod with the completion of the golf swing. Stated otherwise, the desired ending position of the alignment member 16, rotates the end of the alignment member 16 approximately 180 degrees from the position at full backswing, while the rod 16 is aligned in a plane relative to the ground similar to a plane relative to the ground at full backswing. Also, at the ending position of follow through, the right end of the indicator rod 16 should point slightly up and rotated approximately 90 degrees from its starting position.

The position of the ends of the indicator rod 16 may also be utilized by the golfer to identify undesirable body and arm positions throughout a golf swing. For example: if a golfer's body rotates less than 90-degrees in the backswing this should be readily visible to the golfer based on the position of the indicator rod. Also in the backswing, if the left end of the indicator rod dips down below the right end, or if the left end rises up above the right end, the golfer is not swinging the club on the proper plane and will have difficulty squaring the clubface to the intended target line at impact. Further, in the downswing, if the golfer does not rotate the right end of the indicator rod past the left end both power and accuracy will be reduced.

Turning attention now to the Figures, embodiments of the golf swing 30 training device 10 of the present invention will now be described in more detail and are generally shown in FIGS. 1-4. The training apparatus 10 of the present invention generally includes arm bands 12 and 14 that fit at least partially around the outside portion of a user's upper arms just above elbows, for example. The arm bands are preferably flexible and are constructed to bend or expand to different sized arms. FIGS. 8 and 9 illustrate an example of hinged expandable arm bands 32 and 34. The arm bands 32 and 34 are partitioned and held together with a hinge 38 that allows a free end of the arm band to rotate about a pin 36 of the hinge 38. A portion of the pin 36 includes teeth that restricts the hinge from rotating. The two-piece arm bands and pins allow the arm bands to both ratchet and lock for custom sizing. The lock mechanism or pin 36 is actuated from a first locking position (see FIG. 8) to a second rotating position (see FIG. 9) to allow the user to adjust the relative size of the arm band. When the lock mechanism is locked, a portion of the teeth of the pin holds the arm band in a position having the adjusted relative size of the arm band. Those skilled in the art will appreciate that other adjustments, clasps, and hinges, for example, may be incorporated into the arm bands to provide an adjustable and expandable arm band. Without limitation intended, for example, the expandable arm bands may be divided but held together with a lock mechanism so that a tab portion of one section of the arm band slides in a slot of the other section. The two-piece arm bands with lock mechanism, with tabs and slots, would allow the arm bands to both increase or decrease a relative diameter of the arm band, thereby allowing for custom sizing of the arm band. Further, the inside of the arm bands 12 and 14 may be lined with felt or other padding to further provide a comfortable fit against the user's arm. The same may be accomplished using arm bands of different sizes.

The alignment member 16 may be of known suitable construction, including, for example, a long, light-weight rod. The alignment member 16 is engaged with the arm bands through coupling brackets 18 and 20. Each bracket is preferably provided with at least two bushings that are adapted for receiving the alignment rod, wherein the plurality of bushings provides stability to the rod 16 as it slides through the bushings. First coupling bracket 18 includes bushings 24 having apertures sized to allow the alignment member to slide through the aperture. In the preferred embodiment, the bushings 24 are constructed of a compressible rubber and the aperture has an inner diameter that is slightly less than the outer diameter of the alignment member 16. In this manner, when the rod 16 is slid into bushing 24 the rubber compresses but provides a frictional resistance to the sliding of the rod 16 within the bushing 24. It may be said that the bushing 24 has a high coefficient of friction because the rod 16 meets resistance when sliding in the bushing 24. The second coupling bracket 20 includes bushings 26 having an aperture that is sized to allow the alignment member to slide through the aperture. In the preferred embodiment, the bushings 26 are constructed of a plastic nylon, polypropylene, polytetrafluroethylene (PTFE) or other suitable plastic of desirable, known construction having a low coefficient of friction. The bushings 26 have an inner diameter that is slightly larger than the outer diameter of the alignment member 16. In this manner, when the rod 16 is slid into bushing 26 the rod 16 is met with little resistance.

A resilient member or band 22 interconnects the arm bands 12 and 14 in spaced relation. The band 22 may be constructed of elastic or other suitable resilient material and the length may be adjusted depending on the desired separation distance between the arm bands. As the distance between the arm bands increases and decreases the alignment member 16 slides in the bushings 26 of the coupling bracket 20. Swivel mechanisms 28 and 30 of known suitable construction are used to couple the arm bands 12 and 14 to the coupling brackets 18 and 20. When the golfer swings the golf club from the backswing through the follow through, the swivels 28 and 30 allow the arm bands to pivot slightly, providing freedom of movement and additional comfort for the user.

Referring now to FIG. 5, a golfer is shown holding a golf club in a backswing position 40 and 42. The alignment member is shown with the ends of the alignment member in a preferred orientation relative to the ground and golf ball. With reference to the golfer identified as 44, the position of the golfer's hips and shoulders are not preferred and the ends of the alignment member 16 are consequently in an undesired orientation relative to the ground and golf ball.

FIG. 6 depicts a front view of a sequence of preferred orientations 50-70 of a golfer and the corresponding preferred position of the alignment member 16. As the golfer first addresses the ball 50 the longitudinal axes of alignment member 16 aligns with the approximate preferred trajectory of the ball and the end of the alignment member near the ball is slightly higher than the end further away from the ball. As the golfer rotates the arms and body to move the golf club backward 52-56, and as the golfer begins to swing the club forward 58-60, the longitudinal axis of the alignment member 16 should remain relatively parallel with the ground. As the golfer 62 swings the golf club near the golf ball 62, the position of the alignment member should return to a position similar to the position when the ball is addressed (50). As the golfer continues to swing the club to follow through 64-70 the end of the alignment member, that was initially furthest from the ball, should rotate past the initial position and its finish position should point towards the approximate desired trajectory of the ball.

FIG. 7 depicts a side view of a sequence of preferred orientations 80-100 of a golfer and the corresponding position of the alignment member 16. As the golfer first addresses the ball 80 the longitudinal axes of alignment member 16 aligns with the approximate preferred trajectory of the ball and the end of the alignment member near the ball is slightly higher than the end further away from the ball. As the golfer rotates the arms and body to move the golf club backward 82-86, and as the golfer begins to swing the club forward 88-90, the longitudinal axis of the alignment member 16 should remain relatively parallel with the ground. As the golfer 92 swings the golf club near the golf ball the position of the alignment member should return to a position similar to the position when the ball is addressed 80. As the golfer continues to swing the club to follow through 94-100 the end of the alignment member, that was initially furthest from the ball, should rotate past the initial position of the ball and its finish position should point towards the approximate desired trajectory of the ball. As depicted in the sequence of golfing positions, the golf swing training apparatus 10 provides a visual indicator of the position of the golfer's arms and body that is visible without requiring a turn of the golfer's head.

In an embodiment of the invention, the bands 12 and 14 can be used as leg bands. Thus, the training apparatus 10 can be used as a leg position indicator with bands located just above the knees. Optionally, the size of the bands can be varied. In another embodiment of the invention, interchangeable and differently sized foam inserts are included for insertion into the bands in order to accommodate differently sized limbs.

The foregoing is offered primarily for purposes of illustration. It will be readily apparent to those skilled in the art that the materials and their proportions, as well as the operating conditions, procedural steps and other parameters of the inventions described herein may be further modified or substituted in various ways without departing from the spirit and scope of the invention.
