Abstract
At least one, and preferably a pair, of golf ball markers with magnets incorporated therein are employed in combination with a golf putter as a putting training aid. The golf ball markers may be placed a short distance apart on the ball-impact impact face of the putter for a golfer to practice putting. If the golfer correctly brings the putter face into contact with the ball, the ball will be impacted by the center of the face directly between the two magnetized ball markers. If the golfer's putting stroke is not correct, one or the other of the ball markers will strike the ball, thereby creating a tactile sensation transmitted through the putter shaft that informs the golfer of the error in execution of the putting stroke. Magnetic golf ball markers may also be used in combination with a putter in other ways to develop a putting stroke that is consistently correct. The golfer places two of the golf ball markers with magnets incorporated therein on a golf putting practice surface. One of these markers is placed directly in front of the golf ball and one directly behind it. On the backswing, the magnetic golf ball marker behind the golf ball will spring up onto the sole of the putter head with an audible click if the putter head remains near the golf putting practice surface during the backstroke. As the putting stroke is executed, and with a proper follow through, the ball marker in front of the golf ball will be magnetically attracted to the sole of the putter head if the putter head remains near the golf putting practice surface.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the combination of a golf ball marker which incorporates a permanent magnet in its structure with a golf putter having a club head formed of a material attracted by magnetism and -the use of that combination as an aid for golf putting practice.




2. Description of the Prior Art




During a round of golf quite frequently a golfer will arrive at a green in preparation for a golf putt, but will sometimes have to wait for several minutes for other golfers to complete their shots. During this time the golfer can contemplate the best way to execute the golf putt that is required to maximize the likelihood that the golfer's next putt will drop in the hole. In this connection it is often useful for the golfer to practice a proper putting stance, manner of addressing the ball, and swing of the golf putter club.




Many golfers have difficulty putting because the line of movement of the golf putter during the putting stroke is not precisely perpendicular to the face of the putter. As a consequence, when the plane of the impact face of the putter strikes the golf ball, it does so at a slight angle which will cause the ball to travel along a path at a slight angle to the plane of the putter stroke. Even a very slight error in this regard will result in a putt that travels to one side or the other of the cup.




Numerous putting aids exist which are designed to allow a-golfer to improve their putting strokes. However, conventional training aids involve devices which are too large or cumbersome to be carried along during the actual golf match. Rather, many conventional putting aids are designed for the golfer to utilize in private at a practice location, but not while awaiting a turn on the actual field of play.




SUMMARY OF THE INVENTION




The present invention involves the use of a flat golf ball marker which incorporates a permanent magnet in its structure in combination with a golf putter as a practice aid to golfers for practicing putting. The construction of such a golf ball marker is described in pending U.S. application Ser. No. 09/426,786 filed Oct. 22, 1999. This application is hereby incorporated by reference in its entirety. As described in that application, a golf ball marker into which a magnet has been incorporated may be carried externally on an article of golf clothing into which an iron or steel object has been embedded. Golf ball markers with magnets in them may thereby be worn and prominently displayed on golf hats, caps, sun visors, golf gloves, golf towels, golf bags and other golf accessories.




However, I have devised yet another use of a golf ball marker having a magnet in it. By utilizing such a golf ball marker on a golf putter having a golf club head formed of iron, steel, or any other material that is attracted:.by magnetism, a most effective golf putting training aid is created.




The unique combination of elements of the present invention may be utilized in several different ways to improve the proficiency of a golfer's putting game. The use of a single golf ball marker into which a permanent magnet has been incorporated can be used to advantage in this connection. However, even greater advantages are gained by utilizing a pair of golf ball markers each having a magnet within its structure in combination with a golf putter.




The club head of the golf putter employed in the practice aid of the invention must be formed of a material attracted by magnetism, such as iron or steel. While some golf putter club heads are formed of brass or aluminum, the vast majority are now made of steel, which is attracted by magnetism. A golf ball marker having a magnet within its structure will be attracted to such a golf putter club head and will adhere to it due to the force of magnetic attraction. As a consequence, such a golf ball marker may be utilized in combination with such a golf putter to fine tune a golfer's putting game.




To illustrate, it is well-known that for putting accuracy it is important for the ball-impact face of the golf putter club head to remain vertical throughout a golf putting stroke. In a correct putting stroke the putter club head should be brought straight back and then forward again close to the ground with a rhythmic movement. The ball-impact face should remain vertical during the putting back stroke and also during the putting stroke follow through in order to assure that it is vertical at the critical moment, which is the moment of impact against the ball.




It is also extremely important for the plane of the ball-impact face to be perpendicular to the intended path of travel of the golf ball at the moment of impact. To assure that the ball-impact face is at this orientation when it strikes the golf ball it should be perpendicular to that intended path of travel during the putting backswing and also during the follow through of the putting stroke. Furthermore, it is very important for the sole of the putter club head to remain very close to the putting green during the back stroke and the follow through. However, there is a tendency by many golfers to lift the golf club putter head during the back stroke and during the follow through. As a consequence, the putter club head moves in an arc, rather than in a linear path during the putting stroke. This greatly increases the likelihood of a misdirected putt.




To improve the consistency of a golfer's putting stroke a golf ball marker having a magnet therein may be placed upon the flat ball-impact face of the golf putter club head at a location offset from the “sweet spot” at the center of the club face in the direction of either the heel or the toe of the club head. Therefore, during practice putts a golfer will immediately become aware of an impact against the ball marker if there is an error in execution of the putting stroke that brings the ball marker into contact with the golf ball. The tactile sensation transmitted to the golfers hands through the shank of the putter if the ball marker rather than the center of the ball impact putter face strikes the golf ball is unmistakable.




While use of a single magnetic golf ball marker in this manner is advantageous, the use of a pair of golf ball markers, each having a magnet therewithin, is of considerably greater benefit. That is, one of the magnetic ball markers can be placed on the ball-impact face of the putter between the heel of the club and the midpoint of the ball-impact face. The other magnetic ball marker can be placed on the ball-impact face of the putter between the toe of the club and the midpoint of the ball-impact face. If the golfer executes the putting stroke in such a manner as to strike the golf ball with the club head either too close to the heel or to close to the toe one or the other of the ball markers will strike the golf ball. The golfer is thereby provided with an unmistakable indication of a faulty putting stroke.




Similarly, one or a pair of golf ball markers containing a magnet therein can be utilized to improve a goffer's putting game in another way. Specifically, a magnetic golf ball marker is placed on the putting practice surface a few inches behind the golf ball. During the proper execution of a putting backswing, the putter club head will remain close to the putting surface so that the magnetic ball marker will be pulled onto the sole of the club head as the putter head passes over the ball marker. The transfer of the golf ball marker onto the sole of the putter club head produces an audible sound, namely a “click”. However, if the putter head is lifted slightly from the putting practice surface during the back stroke, as will occur if the putter is swung in an arc in a vertical plane, the distance of separation of the club head sole from the magnetic ball marker resting on the putting practice surface will be too great for the ball marker to be attracted onto the club head sole.




Likewise, another magnetic ball marker may be placed a few inches ahead of the golf ball. If the golfer lifts the putter head away from the putting practice surface during execution of the putting stroke, the distance between the magnetic ball marker resting on the putting practice surface in front of the position of the golf ball and the sole of the putter club head will be great enough so that the ball marker will not be lifted by the force of magnetism up to the club head sole. On the other hand, if the putter club head sole remains close to the putting practice surface during the putting stroke follow through, the magnetic attraction of the magnetic ball marker to the sole of the putter club head will cause the magnetic ball marker to be lifted from the putting practice surface and to magnetically attach itself to the club head sole. This transfer is accompanied by an audible sound.




In one broad aspect the invention may be considered to be a golf putting training aid comprising in combination: a golf putter having a club head formed of a material attracted by magnetism and having a flat front ball-impact face and a sole extending rearwardly from the front ball-impact face, and at least one flat golf ball marker including a permanent magnet permanently incorporated therein, wherein the golf ball marker is removably detachable relative to the golf putter club head. While a single golf ball marker having a magnet in it may be used to advantage, the invention preferably is comprised of a pair of such golf ball markers.




In another broad aspect the invention may be considered to be a method of golf putting training on a putting practice surface utilizing a golf ball, a golf putter having a shaft with opposing ends and a grip at one hand and a club head formed of a material attracted by magnetism at an opposite end. The putter club head has a heel, a toe, a sole, and a flat front ball-impact face. At least one flat golf ball marker that includes a permanent magnet permanently incorporated therein is also utilized.




The steps of the invention comprise: placing the golf ball upon the golf putting surface; placing the golf ball marker on the ball-impact face offset from a point midway between the heel and the toe, whereupon the golf ball marker is held in position by magnetic force; holding the putter by the grip to address the golf ball with the club head ball-impact face oriented in a plane perpendicular to the putting practice surface while holding the sole of the club head proximate to the putting practice surface; drawing the putter club head away from the golf ball while holding the ball-impact face of the club head perpendicular to the putting practice surface and the sole of the club head proximate thereto; and bringing the putter club head toward the golf ball to strike the golf ball with the ball-impact face perpendicular to the putting practice surface while avoiding contact between the golf ball marker and the golf ball.




In still another broad aspect the invention may be considered to be a method of golf putting training on a putting practice surface utilizing a golf putter having a shaft with a grip at one end and a club head formed of a material attracted by magnetism at an opposite end. The club head has a flat, front ball-impact face and a sole extending rearwardly from the front ball-impact face. The method further utilizes at least one flat golf ball marker that includes a permanent magnet permanently incorporated therein.




The steps of this aspect of the invention comprise: establishing a spherical golf ball position atop the golf putting practice surface; placing the golf ball marker on the golf putting practice surface within six inches of the golf ball position, whereby an imaginary straight horizontal ball travel alignment line passing directly beneath the centers of both the golf ball position and the golf ball marker defines a desired direction of golf ball travel when the golf ball is putted and an imaginary flat vertical impact-face plane is tangent to the golf ball position and intersects and is perpendicular to the straight horizontal ball travel alignment line between the centers of the golf ball and the ball marker; holding of the putter by the grip to address the golf ball with the ball-impact face of the club head parallel to the impact-face plane and between the golf ball and the ball marker and with the club head sole located proximate to the putting practice surface; drawing the putter club head away from the golf ball and toward the ball marker in a backswing stroke while holding the putter ball-impact face parallel to the impact-face plane and the sole proximate the putting practice surface, whereby the ball marker is drawn by magnetism up into contact with the putter club head sole while making an audible noise as it does so; and bringing the putter club head toward the golf ball position in a putting stroke while maintaining the ball-impact face perpendicular to the desired direction of golf ball travel and with the club head sole remaining proximate the putting practice surface. In this aspect the method of the invention may be performed with or without a golf ball.




Preferably the method of practice is performed utilizing a pair of golf ball markers, each of which includes a permanent magnet within its structure. In the aspect of putting practice in which a magnetic ball marker is placed upon the ball-impact face of the putter club head to ensure that the center of the ball-impact face strikes the golf ball, one magnetic ball marker is placed between the club head heel and the point of the ball-impact face midway between the heel and the toe. The other magnetic ball marker is placed between the club head toe and the point of ball-impact face midway between the heel and the toe.




In the aspect of putting practice in which a magnetic ball marker is placed upon the putting practice surface to ensure that the sole of the putter club head remains close to the putting practice surface during the putting stroke, one magnetic ball marker is to placed a few inches to the rear of the golf ball position, while the other magnetic ball marker is placed a few inches in front of the golf ball position. If the putting back stroke is correct, the magnetic ball marker to the rear of the golf ball position will be lifted from the golf putting practice surface by the force of magnetism and attach itself to the sole of the club head as the club head passes over it during the backswing. If the putting stroke follow through is correct, the magnetic ball marker in front of the golf ball position will be lifted from the golf putting surface by the force of magnetism and attach itself to the sole of the club head as the club head passes over it during the follow through of the putting stroke.




The invention may be described with greater clarity :and particularity by reference to the accompanying drawings.

DESCRIPTION OF THE EMBODIMENT





FIG. 1

illustrates a golfer indicated generally at


10


utilizing a golf putter


12


in combination with a pair of identical golf ball markers


14


according to the invention as a practice aid for golf putting. The golfer


10


first places the golf ball markers


14


on the ball impact face


28


of the golf putter head


26


. The ball markers


14


are each located off-center on the ball-impact face


28


, one closer to the heel


40


and the other closer to the toe


42


. The golfer


10


then observes the alignment of the golf ball markers


14


relative to a golf ball


16


while moving the golf putter


12


in a backstroke, indicated by the directional arrow


18


, and then forwardly in an actual putting stroke and follow through, as indicated by the directional arrow


20


. By utilizing the golf ball markers


14


for purposes of alignment in combination with the golf putter


12


, the golfer


10


is able to more precisely execute a proper backstroke


18


and putting stroke and follow through


20


so that the golf ball


16


will drop into the cup


22


, even from a far greater distance than is indicated in FIG.


1


.




The golf putter


12


has a shaft or shank


24


, which may be formed of wood, metal, or some plastic composite material. The putter shaft


24


has opposing upper and lower ends. A conventional grip


25


is mounted on the upper end of the putter shaft


24


. At its lower end the shaft


24


terminates in a golf putter club head


26


. The club head


26


of the golf putter


12


must be formed of some material that is attracted by magnetism, typically steel.




The configuration of the golf club head


26


is best illustrated in the detail drawings of

FIGS. 2 and 3

. The golf club head


26


has a flat, planar front ball-impact face


28


, and a sole


30


extending rearwardly from the front ball-impact face


28


. The golf club head


26


also has a back


32


that rises sharply upwardly from the sole


30


and perpendicular thereto.




Above the central region


32


there is a shelf


36


that has a flat surface oriented perpendicular to the front face


28


and which is generally parallel to the sole


30


. A rear abutment face


38


extends up from the planar shelf


36


and is oriented perpendicular thereto, as illustrated in FIG.


2


. The putter club head


26


is configured with a conventional heel


40


at its inboard end which is joined to the shaft


24


and a conventional toe


42


at its outboard end, remote from the connection to the shaft


24


.




The construction of the ball marker


14


is illustrated in FIG.


8


. The ball marker


14


is formed of a flat slab


50


of nonferrous material, such as brass or plastic. The slab


50


is stamped to have an outer disk-shaped configuration with a circular upper surface


52


and a circular undersurface


54


. The upper surface


52


of the magnetically inert slab


50


typically bears an indicia which may be a raised embossment, an indented stamping, a painted symbol, decal or design, or any combination of different types of indicia utilized on a conventional ball marker. Very typically, an indicia will identify a particular golf tournament or country club. The undersurface


54


of the nonferrous slab


50


has a central, disk-shaped cavity


56


defined therein. The magnetically inert slab


50


is preferably formed from a material that is somewhat malleable, so that the cavity


56


can be defined by stamping a disk-shaped depression into the undersurface


54


of the slab


50


. Alternatively, the cavity


56


may be formed by milling out material from the slab


50


at the center of the undersurface


56


using an end mill and lathe.




The cavity


56


accommodates and seats a small, flat, disk-shaped magnet


58


so that the magnet


58


can be permanently secured to the magnetically inert slab


50


by force fitting it into the cavity


56


. The magnet


58


may be formed of any material that exerts a permanent magnetic field. The magnet


58


may be formed of magnetized iron, but is preferably a rare earth magnet, such as a Nd—Fe—B (Neodymium/Ferrum/Boron) alloy. Other rare earth magnetic materials which are also sold commercially are: MM Magnet [Magnequench (Bonded NdFeB)], SmCo Magnet (Samarium/Cobalt), and Alnico Magnet (Aluminum/Nickel/Cobalt).





FIGS. 1 through 4

illustrate the use of a pair of magnetic ball markers


14


in combination with the golf putter


12


in one manner of use as a putting practice aid. As shown in those drawing figures, one of the magnetic golf ball markers


14


is positioned on the front ball-impact face


28


of the putter club head


26


, offset from the point


60


located midway between the end of the heel


40


and the end of the toe


42


at a location closer to the heel


40


than the toe


42


. The ball marker


14


may be placed between about one-half of an inch and one inch from the center point


60


of the ball-impact face


28


. The other golf ball marker


14


is located at the same distance from the center point


60


of the ball-impact face


28


, but closer to the toe


42


than to the heel


40


. The ball markers


14


are both equidistant from the center


60


of the ball-impact face


28


. Both of the golf ball markers


14


are held in position against the ball-impact face


28


by the magnetic force of attraction exerted by the magnets


58


which are permanently mounted within the golf ball markers


14


.




The golfer


10


holds the putter


12


by the grip


25


to address the golf ball


16


with the club head ball-impact face


28


just behind the golf ball


16


, as illustrated in FIG.


1


. The club head ball-impact face


28


is oriented in a plane perpendicular to the putting practice surface


62


, as illustrated in FIG.


2


. The sole


30


of the golf club head


26


is held proximate to the putting practice surface


62


, as illustrated in FIG.


3


.




The golfer


10


then draws the putter head


26


away from the golf ball


16


as indicated by the directional arrow


18


while holding the ball-impact face


28


of the club head


26


perpendicular to the putting practice surface


62


and the sole


30


of the club head


26


proximate to the putting practice surface


62


. At the termination of the backswing


18


the club head


26


is at the position indicated in phantom at


126


in FIG.


2


.




The golfer then brings the putter club head


26


toward the golf ball


16


to strike it with the ball-impact face


28


perpendicular to the putting practice surface


62


while avoiding contact between either of the golf ball markers


14


and the golf ball


16


, as illustrated in solid lines in FIG.


2


. If the putting stroke is executed properly the center point


60


of the ball-impact face


28


located midway between the end extremities of the heel


40


and the toe


42


strikes the golf ball


16


while the ball-impact face


28


remains perpendicular to both the golf putting practice surface


62


and an intended line of golf ball travel


68


. The line of golf ball travel


68


may be considered to be a plane projection onto the putting practice surface


62


of a line extending through the center of the golf ball


16


and the point on the rear surface of the golf ball


16


at which the center point


60


of the ball-impact face


28


is supposed to make impact. It should be noted that if the putting stroke is executed properly as described, the spherical curvature of the golf ball


16


will prevent any contact from occurring between either of the golf ball markers


14


and the golf ball


16


.




The alignment of both of the golf ball markers


14


aids a golfer in moving the putter


12


straight to the rear to a backswing position.

FIG. 2

illustrates in phantom at


126


the position of the golf club head


26


at the extreme end of a short backstroke, directly behind the ball


16


. The putter impact face


28


should remain perpendicular to the path of backswing movement, indicated at


18


in

FIGS. 1 and 2

. The golf ball markers


14


provide visual indicia to the golfer


10


that assist the golfer


10


in maintaining a perfect, straight linear backstroke path


18


, so that the forward path of movement


20


of the club


26


passes through the center of the golf ball


16


and directly along the intended path of travel


68


of the ball


16


. Moreover, by using a pair of golf ball markers


14


, the golfer


10


is provided with guides proximate both the heel


40


and the toe


42


of the golf club


12


. The pair of ball markers


14


assist the golfer in maintaining the ball


16


aligned with the center


60


of the ball-impact face


28


. As a result, the forward path of travel of the club head


26


brings the club ball-impact face


28


into contact with the ball


16


at the “sweet spot”, which is a the exact center point


60


of the face


28


, and not off center toward either the heel


40


or the toe


42


of the club head


26


.




The golfer


10


can use one or more of the golf ball markers


14


magnetically attached to the club head


26


as a golf practice aid in practicing putting toward an imaginary cup while awaiting his or her turn to shoot at a putting green. The golf ball markers


14


are held firmly to the ball-impact face


28


of the golf club putter head


26


by the force of magnetic attraction of the magnets


58


to the steel golf club head


26


. The golf ball markers


14


further aid the golfer


10


in that the eyes of the golfer


10


are more likely to remain focused directly on the ball


16


as the ball-impact face


28


approaches the ball


16


to avoid hitting the ball


16


with either of the golf ball markers


14


.




If the golfer


10


brings the putter club head


26


rearwardly in a backstroke other then along the proper backstroke path


18


, as for example along an arcuate path indicated at


70


in

FIG. 4

, the departure of movement of the club head


26


from the proper path


18


will bring the club head


26


to the position indicated at


126


′ in FIG.


4


. While the golfer


10


may not readily detect the misalignment of the ball-impact face indicated at


28


′ in

FIG. 4

, this misalignment will become apparent when the club head


26


is brought forward to strike the golf ball


16


. More specifically, and as illustrated in

FIG. 4

, the exact center point


60


of the ball-impact face


28


will not strike golf ball


16


. Rather, the ball-impact face


28


will strike the golf ball


16


off center.




In the example illustrated in

FIG. 4

, the misaligned position of the golf club head


26


as it strikes the golf ball


16


results in contact between the ball marker


14


located between the center


60


of the ball-impact face


28


and the end of the heel


40


. Contact between the golf ball marker


14


and the golf ball


16


can be felt by the tactile sensation transmitted from the ball marker


14


through the club head


26


, up the putter shaft


24


, through the grip


25


and to the hands of the golfer


10


. The golfer


10


is thereby instantly aware of any improper execution of the putting stroke. A comparable tactile sensation will be felt if the ball marker


14


located between the center


60


and the end of the toe


42


strikes the golf ball


16


.




The combination of a golf putter


22


having a golf club head


26


formed of a material attracted by magnetism and a golf ball marker


14


incorporating a magnet


58


therewithin may be utilized in other ways as a golf putting training aid.

FIGS. 5 through 7

illustrate the manner of practice of the method of the invention in which one golf ball marker


14


is placed a few inches in front of a golf ball position, while a second golf ball marker


14


is placed a few inches behind the golf ball position. This practice technique may be utilized either with or without a golf ball


16


. Either way, the golfer


10


first establishes a spherical golf ball position atop the golf putting practice surface


62


, which in the illustrations of

FIGS. 5 through 7

is the position of the golf ball


16


.




The golfer


10


places one golf ball marker


14


on the golf putting practice surface


62


within six inches of the golf ball


16


and behind the rear face


38


of the golf club head


26


. The lower most ball marker


14


illustrated in

FIG. 5

is in this position along the line of the backswing behind the golf ball


16


. The location of the golf ball marker


14


in this manner defines an imaginary straight horizontal ball travel alignment line


74


passing directly through the centers of both the golf ball position


16


and the ball marker


14


. The line


74


defines the desired direction of golf ball travel when the golf ball


16


is putted. The location of the golf ball marker


14


on the golf putting practice surface


62


in this manner also defines an imaginary flat vertical impact-face plane


76


which is tangent to the golf ball position occupied by the golf ball


16


. The plane


76


intersects and is perpendicular to the straight horizontal ball travel alignment line


74


defined between the centers of the golf ball


16


and the ball marker


14


.




In the example illustrated in

FIGS. 5 through 7

, a second golf ball marker


14


is placed on the golf practice putting surface


62


directly in front of the golf ball


16


. The position of the second marker is indicated by the upper golf ball marker


14


in

FIGS. 5 through 7

. Both of the golf ball markers


14


are located on the ball travel alignment line


74


. The ball markers


14


are located on opposite sides of the vertical impact-face plane


76


from each other and are both preferably placed no closer than two inches to the impact-face plane


76


and no further than about six inches from it.




To practice the manner of implementation of the method of the invention illustrated in

FIGS. 5 through 7

the golfer


10


holds the putter


22


by the grip


25


to address the golf ball


16


with the club head ball-impact face


28


of the club head


26


parallel to and only slightly behind the impact-face plane


76


as shown in FIG.


5


. The ball-impact face


28


is located between the golf ball


16


and the lower golf ball marker


14


at the backswing position. The club head sole


30


is located proximate to the putting practice surface


62


.




The golfer


10


then draws the putter club head


26


away from the golf ball


16


and toward the lower ball marker


14


in a backswing stroke as indicated by the directional arrow


18


in FIG.


6


. While executing the backswing stroke the golfer holds the putter face


28


parallel to the impact-face plane


76


and the club head sole


30


proximate the putting practice surface


62


. When the backswing stroke


18


is properly executed in this manner, the sole


30


of the club head


26


passes directly over the rear ball marker


14


. The ball marker


14


is thereupon drawn by magnetism up into contact with the putter club head sole


30


making an audible “clicking” noise after it leaves the putting practice surface


62


and adheres to be club head sole


30


. This audible sound provides assurance to the golfer


10


that the backswing


18


has been properly executed.




The golfer


10


then brings the putter club head


26


toward the golf ball


16


in a putting stroke and continues forward movement of the putter club head


26


in a proper putt and follow through indicated at


20


in FIG.


7


. This movement strikes the golf ball


16


with the ball-impact face


28


in the ball impact-face plane


76


and with the club head sole


30


remaining proximate the putting practice surface


62


. The continued forward movement of the club head


26


in a proper putt and follow through


20


maintains the front of ball-impact face


28


of the putter club head


26


parallel to the impact-face plane


76


while maintaining the putter club head sole


30


proximate the putting practice surface


62


. With proper execution of the putt and follow through


20


the ball marker


14


in front of the golf ball


16


, which is the upper ball marker


14


in

FIGS. 5 through 7

, is drawn up into attachment to the putter club head sole


30


by the force of magnetism exerted by the magnet


58


during the putting stroke. As the putter club head


26


passes over the uppermost ball marker


14


shown in

FIGS. 5 through 7

, a second audible “click” can be heard as the ball marker


14


located near the end of the follow through leaves the putting practice surface


62


and makes contact with the sole


30


of the putter club head


26


.




If the golfer


10


executes an improper backstroke, for example by bringing the club head


26


up away from the putting practice surface


62


in an arcuate path, the club head


26


will not pass close enough to the magnetic field of the magnet


58


in the ball marker


14


at the backstroke position occupied by the lower ball marker


14


illustrated in

FIGS. 5 through 7

. As a consequence, the ball marker


14


will not attach itself to the sole


30


of the club head


26


, and indeed may not even move at all. The absence of the audible “click” is an instant indication to the golfer


10


of improper execution of the backstroke


18


. Similarly, if the golfer


10


does not execute a proper follow through


20


, the forward or upper ball marker


14


, illustrated in FIGS.


5


through


7


,will not exert a sufficient force of magnetic attraction with respect to the club head


26


to cause it to leave the golf putting practice surface


62


and magnetically adhere to the sole


30


of the golf club head


26


.




It is thus apparent that, if a golfer properly executes a putting stroke utilizing be putter


12


and the ball markers


14


in combination as a putting aid in the manner described in conjunction with

FIGS. 5 through 7

, the golfer will hear a successive pair of “clicks”. These sounds are heard as the club head


26


successively passes over first the rear most ball marker


14


during the backswing and then over the forward ball marker


14


during the follow through. The rear ball marker


14


shown in

FIGS. 5-7

first leaves the golf putting practice surface


62


and magnetically adheres to the sole


30


of the putter club head


26


with an audible click, followed by the forward ball marker


14


. An absence of either of these audible signals indicates to the golfer improper execution of the putting stroke.




Undoubtedly, numerous variations and modifications of the invention will become readily apparent to those familiar with golf putting training systems and aids. For example, there are a number of different types of construction that may be used to create suitable magnetic ball markers. Exemplary alternative magnetic ball markers which may be utilized are described in U.S. application Ser. No. 09/426,786. Also, while the use of an actual golf ball


16


to establish the spherical golf ball position is illustrated in

FIGS. 5-7

, this manner of practice of the invention can be practiced with or without an actual golf ball. Accordingly, the scope of the invention should not be construed as limited to this specific embodiment of the structure of the invention nor the exemplary examples of implementation of the method thereof.
