Description

BACKGROUND OF THE INVENTION

1. Technical Field

This invention generally relates to golf clubs. More particularly, the invention relates to golf putters. Specifically, the invention relates to a golf putter that includes a flange having a transparent surface and an alignment mechanism thereon which helps'the golfer to correctly position the putter head to putt more accurately.

2. Background Information

Golfers are always trying to improve their game and, consequently, they are always seeking out aids, teaching tools, videos and programs that will assist them in improving their game and achieving their potential as a golfer. The golfer may utilize all of these resources yet still encounter problems when they are actually out on the course. Many amateurs presume that the most important part of the game is driving the ball to the green and they consequently spend a lot of their self-improvement efforts in correcting their strokes to minimize slicing or hooking of the ball and to drive the ball as far as possible. While these aspects of the game are important, most golfers tend to drop strokes when they reach the putting green. This is because the typical golfer tends to have little awareness of the position of their body, and especially their head, in relation to the position of the ball when they are putting. The golfer's stance and head position are extremely important in determining where the putted ball will land up once struck. Even if the golfer is aware that their head position and their stance are of great importance for the accuracy of their putt, they may not know if the stance they are actually assuming is correct and appropriate for viewing the correct line to the hole. Typical amateur golfers tend to position the putter head on the grass, glance up at the hole once or twice to try and ensure that they are putting the ball in the correct direction and then they strike the ball. On occasion, the position of the golfer's head relative to the putter head is accidentally correct and the putt is good. At other times, the golfer's head is not in a good position relative to the putter head and the putt is bad. The golfer is therefore inconsistent in their putting and their overall game is weakened.

There is therefore a need in the art for a device which will aid the golfer in more consistently and correctly positioning their head and assuming the correct putting stance.

SUMMARY OF THE INVENTION

The device of the present invention comprises a golf club, and more specifically a putter, that includes a plurality of physical and visual aids for assisting the golfer to more consistently assume a good head and body position for putting and to strike a golf ball more correctly and accurately. The club includes a putter head mounted on a shaft. The putter head is provided with a viewing port that comprises one of an aperture in the putter head and a substantially transparent portion therein. The putter head has a first linear marking thereon and the transparent portion has a second linear marking thereon. The first and second markings are alignable with a remote hole to ensure that the golf ball is putted in the correct direction toward the hole.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, there is shown a golfer 10 holding a golf putter 12 in accordance with the present invention. Putter 12 includes a handle 16, a shaft 18 and a putter head 20. Putter head 20 is illustrated as soled on the ground 14, i.e., putter head 20 is disposed resting substantially horizontally relative to ground 14. Golfer 10 is illustrated standing with their head 21 and eyes 22 positioned correctly over putter head 20, so that golfer 10 is ready to most accurately putt the ball 23 into a remote hole (not shown).

Referring to FIGS. 2-6, and in accordance with a specific feature of the present invention, putter head 20 comprises a generally U-shaped base 24 that engages a removeable flange 26. Base 24 preferably is manufactured from aircraft-grade aluminum and flange 26 preferably is manufactured from stainless steel. The aircraft-grade aluminum gives the putting stroke a soft feel and gives the golfer optimum control of ball 23.

Flange 26 has an upper side 26a and a lower side 26b, with the upper side 26a including a reflective surface, as will be hereinafter described, and the lower side 26b including a non-reflective surface. Flange 26 can be selectively removed from base 24, flipped over through over 180° and reinserted into base 24, depending on whether the golfer wants the reflective surface or non-reflective surface facing outwardly away from the ground 14 and toward his eyes 22. Typically, flange 26 would be retained in base 24 with the reflective surface facing upwardly during practice sessions. During an actual game, flange 26 would be reversed so that the non-reflective surface would face upwardly so that the putter would meet the rules and regulations of the USGA.

Base 24 preferably is an integrally formed member having a front wall 28 and a pair of substantially parallel legs 30, 32 that extend outwardly and rearwardly away from front wall 28. Legs 30, 32 are spaced a distance apart from each other and thereby define a gap 42 between them. Front wall 28 includes a front face 52 adapted to contact ball 23, a back face 54, an upper surface 46 and a lower surface 48. The shaft 18 of putter 12 extends upwardly and outwardly away from upper surface 46. Shaft 18 may be received within an aperture (not shown) in upper surface 46 or it may be welded to upper surface 46. A pair of spaced apart apertures 44 are provided in back face 54 of front wall 28 in the region disposed between legs 30 and 32. As seen in FIGS. 4 & 5, a bottom wall 40 extends rearwardly away from front wall 28 and proximate the lower surface 48 thereof. Bottom wall 40 preferably is generally triangular in shape and extends into gap 42. The outermost side edge of each leg 30, 32 preferably is tapered inwardly so that putter head 20 has an aerodynamic profile that allows air to flow more fluidly over and around putter head 20. Legs 30, 32 terminate in terminal ends 76 and 78 respectively. The bottom wall 40 terminates in an apex 40a that is disposed a distance inwardly of terminal ends 76, 78 of legs 30, 32.

In accordance with one of the specific features of the present invention, upper surface 46 of front wall 28 includes a first linear marking 50 that is disposed substantially at right angles to front face 52 of putter 12. First linear marking 50 is adapted to be lined up with a remote hole (not shown) in which golfer 10 is attempting to sink his golf ball 23. First linear marking 50 preferably is in the form of a groove formed in upper surface 46 and extending between front face 52 and back face 54 of front wall 28. Alternatively, first linear marking 50 may comprise a ridge or a line that is physically marked on upper surface 46 in paint, ink or the like. First linear marking 50 preferably terminates in a small arrow-shaped protuberance 56 which extends rearwardly into gap 42.

In accordance with another specific feature of the present invention, flange 26 is removeably received in gap 42 and is detachably secured to base 24. In the preferred embodiment of the invention, flange 26 is secured to rear surface 54 of front wall 28. However, it will be understood that flange 26 could also be secured to one or both legs 30, 32 or to a combination of the legs 30, 32 and rear face 54 of front wall 28. Flange 26 comprises a housing 58, preferably having an inverted V-shaped back end 60, a substantially planar front end 62 and an intermediate portion 64 disposed between front and back ends 62, 60. Back surface 54 of front wall 28 may be provided with a recess shaped to receive the front end 62 of flange 26 therein. Both of the back end 60 and front end 62 of flange 26 extend laterally outwardly beyond intermediate portion 64 so that an indentation 65 is effectively formed on either side of housing 58. Intermediate portion 64 has an upper surface 64a and a lower surface 64b, with upper surface 64a defining a recess 66 therein. Recess 66 is configured to retain a mirrored plate 68 therein. Both the recess 66 and mirrored plate 68 can be of any desired shape, but mirrored plate 68 preferably is retained within recess 66 by both an adhesive (not shown) and the flanges 64c formed in intermediate portion 64 surrounding at least a portion of recess 66. Second linear marking 70a is inscribed on mirrored plate 68. This second linear marking 70a may be in the form of a centrally disposed groove or ridge or simply be a line that is physically marked on mirrored plate 68 in paint, ink or the like. Second linear marking 70a is designed to be alignable with first linear marking 50 on front wall 28 when flange 26 is oriented in putter head 20 so that the reflective surface 66 faces upwardly and outwardly, as will be hereinafter described.

The lower surface 64b of flange 26 has a non-reflective surface. Lower surface 64b is also provided with a central groove, ridge or line that serves as a second linear marking 70b. This second linear marking 70b is designed to be alignable with first linear marking 50 on front wall 28, when flange 26 is flipped over in putter head 20 so that the non-reflective surface faces upwardly, as will be hereinafter described.

Flange 26 is secured to base 24 by a plurality of fasteners 72 that are inserted into holes 74 in front end 62 of flange 26 and then into threaded apertures 44 in rear face 54 of front wall 28. As seen in FIGS. 4 & 5, fasteners 72 preferably are Allen screws that are rotatable by way of an Allen key (not shown) that is inserted through apertures 61 in back end 60 of housing 58. When fasteners 72 are rotated in a first direction, they secure flange 26 to base 24. When fasteners 72 are rotated in a second direction, they release flange 26 from base 24. When flange 26 is secured to base 24, the back end 60 of flange 26 preferably is substantially continuous with the terminal ends 76, 78 of legs 32, 30 respectively, so that putter head 12 has an aerodynamic trailing edge. Flange 26 is secured to base 24 in such a manner that when legs 30, 32 are resting on ground 14, flange 26 is held a spaced distance above bottom wall 40 (FIG. 5) resulting in less drag on the putter 12 as the stroke is executed. This distance is ideally around 4/10 inch.

In accordance with another specific feature of the present invention, each leg 30, 32 includes a longitudinal bore 34, 36 (FIG. 6) configured to receive one or more weights 38 therein. The weights 38 provided may be of any suitable size, such as around 15 g or 30 g each, and one or more weights 38 may be selectively inserted into one or both bores 34, 36. This enables golfer 10 to balance putter head 20 in a manner that is pleasing to the golfer. Weights 38 preferably include a threadable portion 38a (FIG. 6) that engages an internally threaded portion 34a, 36a of bore 34, 36 respectively. Each weight 38 may be provided with a recess (not shown) which allows it to be inserted or removed by an Allen wrench. It should be noted that the gap 42 formed between legs 30 and 32 in conjunction with weights 38 results in a putter head with an increased moment of inertia and a center of gravity that is positioned about 1.4″ from the club face. This reduces the backspin in the golf ball 23 and results in a smoother stroke.

Referring to FIG. 8, there is shown a differently shaped flange 126 for engagement in putter head 20. Flange 126 has an upper surface having a shaped mirrored insert 168 including a second linear marking 170a. Flange 126 has a V-shaped back end 162, the apex 162a of which is disposed inwardly of the terminal ends 76, 78 of legs 32, 30. All other components of flange 126 are substantially identical to that of flange 26, including the feature that the lower surface (not shown) of the flange 126 has a non-reflective surface and a second linear marking thereon. Back end 162 of flange 126 is again substantially continuous with terminal ends 76, 78 of base 24.

FIG. 9 illustrates yet another shape of flange which is indicated generally at 226. Flange 226 includes a peripheral wall 262 that is not substantially continuous with terminal ends 76, 78 of legs 32, 30. Flange 226 includes an upper surface having a mirrored insert 268 therein and a lower surface (not shown) that is non-reflective. As with previous embodiments, flange 226 is easily removed by unscrewing the Allen screws (not shown) that secure it to the base 24. It will be understood that any suitably shaped flange can be received within the gap 42 between legs 30, 32 of base 24 without departing from the spirit of the present invention.

Referring to FIGS. 10-15, putter 12 is used in the following manner. (It should be noted that the specific elements of the putter head, save for the front wall and reflective insert, have been removed from these figures for the sake of clarity.) When the golfer is preparing to putt, he places putter head 20 on the ground 14. Normally, the golfer would not be able to determine very easily if the putter head was soled or not, i.e., if the putter head 20 was lying with both the toe portion 20a and heel portion 20b in contact with the ground 14. As will be described hereinafter, the putter 12 of the present invention solves this problem.

FIGS. 10 and 11 illustrate the situation where toe portion 20a is out of contact with ground 14 and as a consequence, from the viewpoint of the golfer, the first linear marking 50 lies closer to the golfer than does the second linear marking 70a. The non-alignment of first linear marking 50 and second linear marking 70a tells the golfer that he does not have putter head 20 soled properly. The fact that the first linear marking 50 is disposed closer to the golfer than the second linear marking 70a, lets the golfer know that toe portion 20a is lifted off ground 14.

FIGS. 12 and 13 illustrate the situation where heel portion 20b is out of contact with ground 14. In this instance, first linear marking 50 is disposed further away from the golfer than is second linear marking 70a. This tells the golfer that the heel portion 20b is lifted off the ground 14.

FIGS. 14 and 15 illustrate the situation where putter head 20 is correctly soled on ground 14. The golfer can tell the putter head is correctly positioned because first linear marking 50 lies in complete alignment with second linear marking 70a.

FIG. 16 illustrates a putter head 20 that is engaged with a fourth embodiment of a removeable flange, which flange is generally indicated at 326. Flange 326 is secured to rear surface 54 of front wall 28 of base 24. However, it will be understood that flange 326 could also be secured to one or both legs 30, 32 or to a combination of the legs 30, 32 and rear face 54 of front wall 28. Flange 326 is substantially identical to flange 26 except that flange 326 is at least one of a reduced size and different weight to flange 26. When flange 326 is engaged with base 24, the V-shaped back end 360 of flange 326 terminates a distance inwardly from terminal ends 76, 78 of base 24. Flange 326 includes a mirrored plate 368 on an upper surface thereof and is non-reflective on a lower surface (not shown). As with previous embodiments, flange 326 is provided with a second linear marking 370a that serves as an extension of first linear marking 50 on front wall 28. Flange 326 may be either lighter or heavier than flange 26. The different length and weight of flange 326 relative to flange 26, allows the golfer the opportunity to change the center of gravity of putter head 20 and to thereby alter the characteristics of the putter. The center of gravity of putter head 20 can be shifted forwardly toward front face 52 by using flange 326. The center of gravity of putter head 20 can be shifted rearwardly toward terminal ends 76, 78 by using flange 26. This is especially useful in pendulum type motions and different loft angles. If putter 12 has a face 52 with negative loft (e.g., −6 degrees) then switching the center of gravity from the front to the back or from the back to the front of the putter head 20 by engaging the appropriate flange 26 or 326 therewith may be beneficial to the golfer's game. If the golfer drags putter 20 straight back and straight through the ball, he might find that the ball rolls better when the center of gravity of putter head 20 is somewhere between the front face 52 and middle section A-A′ of the putter head 20. If the golfer has a pendulum motion to their backswing, then moving the center of gravity of putter head 20 to between the middle section A-A′ and terminal ends 76, 78 may be beneficial. The golfer is therefore able to select the appropriate size and weight flange 26, 326 to change the center or gravity of the putter head. The position of the center of gravity of the putter head 20 may also make a difference in the roll of the ball depending on whether the golfer positions the ball off his front foot or in the middle of his stance. It would be beneficial to position the center of gravity in the middle section A-A′ or just off the front face 52 of putter 12 by selecting a shorter flange 326 if the golfer places the ball more toward his front foot. This way the club face will stay parallel to the ground and will tend to strike the ball squarely at impact. If the golfer places the ball in the middle of his stance, then the center of gravity of putter head 20 would be more beneficially positioned toward the terminal ends 76, 78 of head 20. This could be achieved by selecting a longer flange 26. This will create a more pendulum-like action, allowing the club to strike the ball on the upstroke and will tend to eliminate “blocking” or striking the ball on the downstroke, which tends to cause hopping/skipping or backspin in the struck ball.

FIG. 17 illustrates a fifth embodiment of flange, being the flange indicated generally at 426. Flange 426 is substantially identical to the flange 226 shown in FIG. 8, except flange 426 is again of a diminished size and different weight to flange 226. Flange 426 includes a peripheral wall 462 that is not substantially continuous with terminal ends 76, 78 of legs 32, 30. Peripheral wall 462 terminates a distance inwardly of terminal ends 76, 78 of base 24. Flange 426 includes an upper surface having a mirrored insert 468 therein and a lower surface (not shown) that is non-reflective. Mirrored insert 468 also includes a second linear marking 470a that aligns with the first linear marking 50 on base 24. As with previous embodiments, flange 426 is easily removed by unscrewing the Allen screws (not shown) that secure it to the base 24 and this makes it easy for the golfer to switch between various length, weight and shape flanges and to thereby change the putting characteristics of his putter. It would be beneficial if the golfer places the ball to more toward his front foot, then shifting the center of gravity of the putter head to proximate the middle section B-B′ or just off the front face 52 can be achieved by selecting a shorter flange 426. The golfer could have provided to him a range of shorter flanges that are of different weights. In this instance, selecting one of the shorter but heavier flanges 426 will cause the movement of the center of gravity to be even more pronounced.

If the golfer places the ball in the middle of his stance, then the center of gravity of putter head 20 would be more beneficially positioned toward the terminal ends 76, 78 of head 20. This could be achieved by selecting a longer and/or heavier flange 26. This shift in the center of gravity will create a more pendulum-like action, allowing the club to strike the ball on the upstroke and will tend to eliminate “blocking” or striking the ball on the downstroke.

It is envisaged that putter 12 might be sold as a base 24 that may be selectively engaged with any one of a plurality of flanges that are manufactured in different shapes, weights or lengths. The golfer would then select a first-shaped flange of his choice and attach the same to the base 24. If he decides that the selected first-shaped flange is not helping him in the manner he desires, he could simply detach the first-shaped flange and replace it with a second-shaped flange. The golfer might alternatively select a different length or weight of flange to purposefully change the center of gravity of the putter head 20 to compensate for or enhance his putting style.

The golfer can train himself to correctly position his head by utilizing the mirrored inserts 68, 168, 268, 368 or 468 that is provided on any of the shaped flanges 26, 126, 226, 326 and 426. For instance, when the mirrored insert 68 of flange 26 is facing upwardly on putter head 20, the golfer will be able to see the reflection 22a of one or both of his eyes 22 in insert 68. When putter head 20 is properly soled on ground 14, the golfer would move his head until the reflection 22a of his eyes 22 is disposed along second linear marking 70a or just slightly below second linear marking 70a. Repeated positioning of his head in this manner will help the golfer train himself to correctly position his head under circumstances where the flange 26 is positioned with the non-reflective surface facing upwardly and toward him.

Putter 12 is also designed so that the golfer can add weights 38 into one or the other or both of the bores 34, 36 in legs 32, 30 in order to balance putter head 20 and thereby reduce his tendency to hold the putter head with either the toe portion 20a or heel portion 20b out of contact with ground 14. Alternatively, if the golfer finds that he plays better with the putter in a slightly unbalanced mode, he can add one or more weights to one or the other bore 34, 36 to cause the putter head 20 to be more easily held in the toe-up or heel-up position. The golfer can also utilize the relative positioning of first linear marking 50 and second linear marking 70a or 70b to determine how to habitually hold putter 12 if they wish to play with the putter head in the toe-up or heel-up position. If they wish to play with putter head 20 in toe-up position, then shaft 18 is pulled slightly toward the body to ensure that first linear marking 50 is positioned closer to the body than is second linear marking 70a or 70b. If the golfer wishes to play with putter head in the heel up position, then they push shaft 18 slightly away from their body to move first linear marking 50 so that it lays further from their body than does the second linear marking 70a or 70b.

The golfer is trained by frequent and regular use of the alignment mechanism, i.e., the first and second linear markings 50, 70, to consistently position their head relative to the putter head 20; and to position the putter head 20 in a particular manner relative to the ground; and to line up a putter head with the ball and with a remote flag/hole. Regular use of the weights 38 also help the golfer to more consistently hold the putter at a particular angle. Essentially, all of these aids help the golfer develop his muscle memory by helping him to consistently position his body and most specifically position his shoulders, head and eyes relative to the putter head.

It will be understood that while flange 26 is shown as reversibly connected to said front wall 28, flange 26 could alternatively be connected to one or both legs 30, 32 or to said legs and said front wall. Furthermore, while the preferred embodiment has shown the flange 26 mounted within a gap 42 defined between legs 30, 32, flange 26 could alternatively be mounted in a recess formed in the putter head rearwardly of front wall 28.

FIGS. 18 and 19 show a sixth embodiment of the flange in accordance with the present invention, said flange being generally indicated at 526. Flange 526 is substantially identical to the flange 26 shown in FIG. 3 in that flange 526 comprises a housing 558, preferably with an inverted V-shaped back end 560, a substantially planar front end (not shown) and an intermediate portion 564 disposed therebetween. Flange 526 may be fixedly secured to putter head 20 or may be detachable therefrom. Both of the back end 560 and the front end of flange 526 extend laterally outwardly beyond intermediate portion 564 so that an indentation 565 is effectively formed on either side of housing 558. Intermediate portion 564 has an upper surface 564a and a lower surface (not shown), with upper surface 564a defining a recess 566 therein. A complementary shaped plate 568 is retained within recess 566, preferably by both an adhesive and flanges 564c of intermediate portion 564 that surround recess 566.

In accordance with a specific feature of the present invention, putter head 20 includes a viewing port through which objects outwardly from the lower surface of the putter may be viewed. The viewing port may constitute an aperture in putter head 20 which extends between the upper and lower surfaces thereof. Alternatively, the viewing port may be provided as an aperture in a fixed or detachable flange 526 or, as is illustrated in FIG. 18, a substantially transparent insert or plate 568 in flange 526. Plate 568 preferably is manufactured from an acrylic material and is therefore see-through, allowing the golfer to see the ground or objects such as the ball 23 beneath plate 568. Plate 568 is provided with a second linear marking 570a in the form of a centrally disposed groove, ridge or a line that is physically marked thereon in paint, ink or the like. Second linear marking 570a is designed to be alignable with first linear marking 50 on front wall 28. Both of the first and second linear markings 50, 570a are alignable with remote objects, such as flags at remote golf holes. The mechanism for aligning first and second linear markings 50, 570a with each other has been described herein with reference to previous embodiments of the golf putter.

The golfer uses putter 20 which incorporates the viewing port, and particularly the transparent plate 568 in flange 526 in the following manner. The golfer stands behind the ball and locates the center of the cup by looking through the viewing port or transparent plate 568. He then aligns one or both of the first and second linear markings 50, 570a with the center of the cup (as indicated by the remote flag) and tracks the line all the way back to the ball. The putter head 20 is positioned so that the second linear marking 570a bisects the ball and thereby provides a determined direction that the center of putter head 20 needs to travel through the ball in order for the ball to be directed toward the hole. Keeping this orientation, the putter head is positioned adjacent the ball with the second linear marking 570a centered through the ball and aligned with the determined direction of travel. The stroke is then played.

The golfer may decide to take a practice swing before playing the ball. In order to do this, the putter head must be passed over the top of the ball in the determined direction. As the practice stroke is played, the golfer views the apparent travel of the ball under the putter head by looking through the viewing port or transparent plate 568. He then compares the apparent travel of the ball under the head with one or both of the first and second linear markings 50, 570a. If the ball is not traveling substantially in line with one or both of the first and second linear markings, the golfer makes any necessary adjustments to the orientation of the putter head to cause the direction of apparent travel to become aligned with the first and second linear markings and thereby with the determined direction of travel. Once he decides the determined direction and apparent direction are one and the same, the golfer positions the putter head adjacent the ball so that first and second linear markings 50, 570a are aligned with each other and so that the ball is bisected by first and second linear markings 50, 570a. Then the stroke is played.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of the invention are an example and the invention is not limited to the exact details shown or described.
