A golf club having such a training device integral with the club or removably associated with the club.

Description

Training Device for Golf Swing

[0001] This application claims priority to, and claims under 35 U.S.C. §119(e)(1) the benefit of the filing date of, US provisional application serial number 63/012,119 filed April 18, 2020, the entire disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

[0004] As used herein, unless specified otherwise, the recitation of ranges of values, a range, from about “x” to about “y”, and similar such terms and quantifications, serve as merely shorthand methods of referring individually to separate values within the range. Thus, they include each item, feature, value, amount or quantity falling within that range. As used herein, unless specified otherwise, each and all individual points within a range are incorporated into this specification, and are a part of this specification, as if they were individually recited herein.

[0005] Generally, the term “about” as used herein unless specified otherwise is meant to encompass a variance or range of ±10%, the experimental or instrument error associated with obtaining the stated value, and preferably the larger of these.

[0006] This Background of the Invention section is intended to introduce various aspects of the art, which may be associated with embodiments of the present inventions.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is schematic cross sectional view of a golf swing training device in accordance with the present inventions.

[0017] FIGS. 2A, 2B and 2C are partial cross sectional illustrations showing the a club incorporating the swing training device and phases and positions of a good golf swing provided by the club in accordance with the present inventions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In general, the present inventions relate to unique devices to train person to have better golf swings; and to gold clubs incorporating the training device to provide for better golf swings while hitting golf balls.

[0019] Generally, embodiments of the present inventions have a shaft that has a proximal and distal end. The proximal end has a handle for grasping attached to the shaft. Preferably, the handle is a golf club handle. The shaft has a length that is from about 60 inches to about 30 inches, although longer and smaller lengths can be used. The shaft has a sliding weight associated with it. The sliding weight can have a weight of about 3 grams (g) to about 40 g, about 5 g to about 25 g, about 10 g to about 35 g, 60 g and less, 50 g and less, 40 g and less, and larger and smaller weights. The weight should be free sliding, i.e., move with minimal friction. Preferably the weight will move solely by the force of gravity. The weight can be inside or outside of the shaft. The shaft has two stops associated with it. A first stop near the proximal end and a second stop near the distal end. The first stop is located about more about 40% to about 60% of the length of the shaft from the proximal end. The second stop is located about 5% to 20% of the length of the shaft from the distal end. Preferably the second stop is located at the distal end of the shaft.

[0020] In use an individual, e.g., a golfer, grasps the handle of the club with both hands, preferably in a proper or acceptable manner for grasping golf clubs. The individual than raises the shaft through a back swing, to a starting position for the swing, as shown in the figure to the right, where the shaft is behind the body and the distal end is above the head. In this position, the starting or back swing position, the weight is held against the first stop (nearer the handle and proximal end) by gravity. As the swing is started, if a proper swing is utilized the weight will remain against the first stop throughout the vast majority of the swing, well beyond the point where the hands are below the belt line of the individual, and preferably until the very end of the swing when the distal end is down near the ground, i.e., in a position where the club head would strike the ball. At that point if the correct swing was used, graving will start the movement of the weight to the distal end, and gravity and the momentum of the swing will cause the weight to strike the second stop. Thus, if a correct swing is performed the weight will not strike the second stop until the point in the swing where the club head would be striking the ball. In this manner the devices permits one to train for a proper swing, and one having increased lag.

[0021] Turning to FIG. 1 there is provided a golf training device 100. The device 100 has a shaft 101. The shaft forms a hollow circular channel 102. The shaft has a proximal end 103 and a distal end 104. There is a handle 106 on the shaft. A weight 105 is located inside the channel 102 of the shaft. The weight is preferably a 7/16” stainless steel ball bearing. A first stop 108 is located inside the channel 102 of shaft 101. A second stop 109 is located inside the channel 102 of shaft 101. The second stop 109 is at the distal end 104 of the shaft 101. The first stop 108, is preferably 18 ½ inches from the second stop 109. The second stop 109 would be the distal stop and the first stop 108 would be the proximal stop. The length of the shaft from proximal 103 to distal end 104 is preferably 40 inches.

[0022] In use, is the shaft is swung correctly, i.e., in a correct golf swing, the ball bearing 105 will remain against the first stop 108 through out the entire swing until that point in the swing where the club would strike the ball, at which point the ball would contact the second stop 109, making a noise, to let the individual know that the swing was correct. In this manner swings can be practiced, improved and made consistent.

[0023] Turning to FIGS 2A, 2B and 2C, there is shown a actual golf club 201 , having a head 202 that is taken through a swing. FIG. 2A the starting position. FIG. 2B the point in the swing where the hands are below the waist.

FIG. 2C the point where the club head 202 strikes the golf ball 203. The club shaft has the same configuration and dimensions as the training shaft of FIG. 1. From the figures it is seen that the ball bearing 205 remains against the proximal stop from the starting position, through the mid swing position of FIG. 2C until the end position of FIG. 2C where the head is about to strike the ball.
