BACKGROUND

1. Field

The present invention relates to a golf putter among various types of golf clubs for use in playing a golf and, more particularly, to a golf putter for enhancing the rolling straightness of a golf ball directed toward a hole and increasing the accuracy of putting by minimizing the errors and the mistakes in putting and by modifying the hitting surface shape of the putter head. In a typical way of putting until now, a golfer examines the green state and the distance before putting and determines the estimated trace of a golf ball. However, in real putting, the golfer stands looking at the golf ball and turns his face sideway unlike the observation posture that the golfer examined, and bows to the golf ball direction with his waist bent and his eyes turned sideway toward a hole. Then, he putts a golf ball finally depending only on his training experiences and his sense of views while still with the fears and uneasiness from the putting views changed from the observation views and the high possibility in errors raised from the differences between his observation and real putting in views and postures. Therefore, the present invention is directed to provide a golf putter by the configuration of which a golfer can practice swing and set up his posture for putting as the same way as he looked up the target hole at front and watched the estimated trace of the golf ball, and then still stands up beside the golf ball and putts the golf ball just like bowling while keep looking at the golf ball.

2. Description of Related Art

Generally, a swing putter 100 of a golf club includes a grip 101, a shaft 102, and a head 103 as shown in FIG. 1. While a golfer plays a golf and when uses a putter, he is positioned to stand up perpendicularly to the line that the putter moves and the hit ball proceeds which is a putting line, and bend down his waist, lower his or her both arms down, holds the grip 101 of the swing putter 100 and swings the putter left and right and putts the golf ball with the head 103.

As shown in FIG. 2, a golfer executes In-In swing with respect to the center line (L1) of his spine. This is because the circular motion with respect to the spine central line (L1) as axis is natural to follow by the law of nature. Depending on how much are the angle (θ1) that the golfer bows, the angle of his arms (θ2) to the spine central line (L1) and the angle of his views (θ3) that his eyes looks at the golf ball, the traces of golf ball movement, that is, each trace that the golf ball proceeds and travels brings different result.

A golfer generally swings for putting at standard position with respect to the spine central line (L1) while focusing and maintaining the angles (θ1, θ2 and θ3) as shown in FIG. 2. Then, the path for the golf ball 200 to proceed should be the way (T1) as shown in FIG. 3. However, the moving direction of the golf ball 200 in real putting result may be turned to a second direction (T2) as shown in FIG. 3 due to the golfer's body structural feature and his In-In swing as normal. Or, in the case of correcting and adjusting his swing excessively, the moving direction of the golf ball 200 in real swing and putting may be a third direction (T3) as shown in FIG. 3 as the Out-Out swing or Neutral-Out swing.

Generally, golfers practice the swing putting times out of number with putting a straight-shaped iron bar with a predetermined width on stroke area in order to prevent the golf ball 200 from proceeding toward the second (T2) or the third direction (T3), and to make the golf ball 200 proceed straightly along the first direction (T1), and to increase the repeatability. Another stance of the golfer to swing the putter is shown in FIGS. 4 and 5, in which he stands and bows and bends his waist and his arms at right angle (90°) with respect to his spine central line (L1) and he always swings and putts in the same angles and the same length while maintaining the angles of his waist and his arms ninety degrees (θ4=θ5=90°) and keeping the views angle of the golfer (θ6) acute angle. Thus, it was intended to decrease the errors which may depend on mentally and physically different condition. In some case, a long putter (belly putter) may be used as shown in FIGS. 6 and 7 in such way that the top portion of a grip 101 of a putter 100 is fixed to the belly or chest (B1) of a golfer.

As shown in FIGS. 8 and 9, a golfer examines in many directions in order to find out the exact track path reached from a golf ball 200 to a hole in advance before putting. In this step, the golfer may hunker down beside a golf ball, or bend his body, or even lay his face down on the green in order to precisely examine and estimate the track path of the golf ball to the target point (A1). These positions are all proceeding with both two eyes facing at front toward the direction to be examined and seeing the direction of the target hole horizontally.

Meanwhile, when the golfer determines the putting line, and he sets up his body line (L2) for putting, and he finally checks the estimated track path of the golf ball to the target point (A1) finally, it is now that he already bows and his body is bent down (θ1≠θ2≠θ3≠90° in FIG. 2) and he looks at the target point (A1) with turning his face sideway which is shown in FIGS. 10 and 11. With his body bent forward with his eyes views downward at the golf ball and his spine central line angled between them, he has to turn his face sideway as much as 90° so that he results in seeing the target point (A1) in completely different views from initially he examined and estimated the track path of the golf ball. In the instant moment like this, the golfer may be dismayed momentarily as result that he could not find out the target point (A1) or the estimated track path exactly, or he may be confused to make him lose his confidence, which thus results in wrong putting swing. Therefore, the mistakes in swinging and putting bring the problems that the golf ball 200 may be proceeded in the direction (T2 or T3) as shown in FIG. 3.

As shown in FIG. 12, when a golfer swings and putts a golf ball, he hits the golf ball without rolling the ball. Thus, the golf ball 200 slips with no rotation in the first region S1 by the skid phenomenon, and then, rolls in the second region S2. Sometimes, the golf ball may be proceeded to a wrong direction even in the first region S1. Or, the direction and the distance of the golf ball 200 in the second region S2 may be determined depending on the state of the green condition at the interface of the first and second regions S1 and S2. Therefore, the distance to be rolled and the direction of the golf ball proceeding are not as good as examined and estimated previously, and sometimes unexpected results happen. This may be the problems in the swing by hitting, but there existed problems in the features of the hitting face of the head of the conventional swing putter 100.

As shown in FIG. 18, the putting surface 103a of the head 103 is made to have an angle (θ12) mostly open upward. At putting, the golf ball 200 may bounce from the green grass 300 toward up due to the hitting angle (θ11) of the golf ball. The rolling factor (r1) of the ball according to the swing trace path may be reduced by the hitting angle (θ11) and may be changed to reverse-rolling factor (r2) so as to occur skid phenomenon and bring undesirable results. In order to overcome this problem and correct this fault, a golfer often executed swing by forcibly raising the head 103 upward, but the results just bring the swing errors such as putting to the direction of T2 or T3 in FIG. 3

Further, a normal swing must be executed along the direction (t1) by the conventional swing putter 100 as shown in FIG. 13, but swing and strike out of sweet spot (t2, t3) often occurs. Specifically, many problems and bad results in putting are brought in the putting direction or putting distance because of the errors or mistakes of, such as the angle (θ7) from the strike by In-Out swing shown in FIG. 14, or the angle (θ8) from the strike by Out-In swing shown in FIG. 15, and rather than the hitting direction of the face 103a of the head 103 to the golf ball 200 is maintained perpendicular to each other as normal as shown in FIG. 13, the hitting angle (θ9) of the head 103 is closed swing as shown in FIG. 16, or the hitting angle (θ10) of the head 103 is open swing as shown in FIG. 17, and so on.

SUMMARY

Embodiments of the present invention provide a golf putter for use in putting a golf ball enabling a golfer to swing and putt a golf ball by the new posture with the new configuration of the putter while solving and improving the problems of the golf playing by conventional typical putters and changing the structure of the conventional typical putters.

Embodiments of the present invention provide a golf putter enabling a golfer to swing and putt a golfer ball while standing at the same location where he or she examined the green state and the distance to a target hole and estimated the travel trace of the golf ball and imagined his or her putting line, and enabling the golfer to strike the golf ball while he or she can still look at the front and watch the golf ball moving similar to the bowling posture.

Embodiments of the present invention provide a golf putter enabling a golfer to stand on the side of a golf ball, and swing and putt the golf ball while keep looking at the front and watching the putted golf ball, which is named as a look & watching side swing putter (SSP), in short, referred to as SSP. The SSP of the present invention reduces putting errors raised from the putting postures and differences in views by use in conventional typical putters, and decreases the strokes to wrong directions.

Embodiments of the present invention provide a look & watching side swing putter (SSP) for improving the straight-lined movement of the golf ball during putting by decreasing skidding and increasing rolling of the putted golf ball with the putting surface of the putter head being reversely cambered.

Embodiments of the present invention provide a look & watching side swing putter (SSP) for putting a golf ball to roll naturally and smoothly by providing a shaft fixing point attached and fixed to the putter behind the putting surface of a putter head, and for increasing the surface friction of the putter against the golf ball toward its rotation direction at the moment of putting, thus to produce top spin of the golf ball by forming a groove aligned in parallel on the putting surface of the putter head.

Embodiments of the present invention provide a look & watching side swing putter (SSP), which is configured such that the lower edge on the putting surface of the putter head is made round and the above groove of the putting surface of the head is extended to this round-shaped edge in order to reduce putting errors which may occur by hit and impact of the golf ball on the lower corner portion of the head putting surface so that the putted golf ball moves toward wrong direction which is unpredicted and unwanted direction.

Embodiments of the present invention provide a look & watching side swing putter (SSP) for minimizing the errors results from the golf ball strike out of a sweet spot and preventing open or closed club face swing by forming the head such that its center of mass is distributed to both side ends.

Embodiments of the present invention provide a look & watching side swing putter (SSP) for considering the individual variation to the maximum in putting and reducing the errors due to these differences among individuals in order to improve the golf ball movement to straight-lined direction and allow consistent putting in results or posture by forming adjust weights on both side ends of the back portion of the head.

Embodiments of the present invention provide a look & watching side swing putter (SSP) in which a first indicator line and a second indicator line are respectively formed on the top surface of the putter head and the lower portion of the shaft, for two lines being connected to each other, and thus for a golfer to enable check the directional accuracy in his swinging and putting while seeing these two indicator lines moving by his own eyes in training or playing games in order to achieve good reproducibility in the direction.

In accordance with an aspect of the present invention, the look & watching side swing putter may include a second grip a golfer taking a grip on by one hand with his or her palm facing a first target direction; a second shaft located up and down the second grip and having a diameter as small as inserted into the fingers of a golfer without irritating; a first shaft extended up and down from the second shaft; a head provided at the bottom end of the first shaft; and a first grip provided at the top end of the first shaft.

The look & watching side swing putter of the present invention may be configured for a golfer to enable execute putting such that the golfer takes a grip on the second grip by his or her main hand with the palm of the main hand faced toward the direction of the first target and the golfer takes a grip on the first grip by the other hand for swinging back and forth without wavering just like the grip of the conventional typical putter or claw grip, and the golfer enable to stand beside a golf ball and swing the putter back and forth and hit the golf ball by the head of the putter and enable to keep watching the putted ball moving.

The second shaft may be configured to have a diameter in the range of φ5 mm to φ7 mm to be inserted between the index finger and long finger of the golfer's hand or between the long finger and the ring finger when the golfer takes a grip on the second grip having a sphere shape.

The head of the putter may be configured such that the putting surface of the head has reverse camber of a predetermined angle.

The predetermined angle of the reverse camber may be made a reverse-incline angle in the range of 1° to 3° to the vertical line to produce top spin in order to improve the straight-lined direction movement of the golf ball being hit.

The head of the putter may be configured such that the fixing point of the first shaft to the head is located on the back of the putting surface of the head in order to increase an upward vector quantity of the head by pendulum movement, and grooves aligned in parallel are formed on the reverse camber of the putting surface of the head in order to reduce the slip of the golf ball, and in order to produce top spin by increasing the surface friction to the rotation direction of the golf ball.

The bottom edge portion of the putting surface of the head may be made to have round shape in order to prevent the putting error raised by the blow impact of the golf ball being hit to the head, and edge grooves are formed on the round-shaped edge portion of the putting surface of the head by extended from the grooves formed as above.

The head may be made such that its center of mass is bidispersive along the both ends back of the putting surface in order to reduce the errors from the hitting results out of sweet spot and reduce the occurrence of the head distorted at swing.

The head may be configured such that an adjust weight is formed on both back sides of the head in order to adjust the error factors in the right and the left direction raised from individual variation of putting and improve the straight-lined directional movement.

The adjust weight may include weight coupling parts formed on both back sides of the head; and adjust weight members having different weights respectively and being able to be selectively coupled to the weight coupling parts.

A first indicator line may be formed on the top surface of the head along its center line in order to help a golfer visually enable see his or her swinging back and forth accurately along the straight line, and a second indicator line may be formed on the lower portion of the first shaft to be extended from and connected with the first indicator line to secure good visual views.

The head may be configured such that a plurality of blades are formed on the bottom surface of the head along the putting direction in order to reduce the friction with green grass occurred when the head contacts and drags at putting and assist the straight-lined movement of the golf ball after being hit.

The second grip may be made to include: a first stopper formed on the outside surface of one side of the second shaft; a plurality of second stoppers formed on the outside surface of the other side of the second shaft; a first hemisphere grip having a first hole, the first stopper being fitted into, and a plurality of nut insertion coupling holes; a second hemisphere grip having a plurality of second holes, the second stoppers being fitted into, and a plurality of second coupling holes, the second hemisphere grip faced with the first hemisphere grip; and bolts/screws for fixing the first hemisphere grip and the second hemisphere grip to the outer circumference surface of the second shaft to form a spherical shape and coupling the first and second hemisphere grips together.

As described above, the look & watching side swing putter (SSP) of the present invention most of all, allows a golfer to stand looking at a target hole in the front way and enable to putt a golf ball while maintaining the first posture as set for putting, and makes him or her keep watching the putted ball moving along the putting line. Therefore, the SSP of the present invention makes the swinging movement for putting a genuine pendulum movement to further reduce the errors and mistakes which often occurred in the past pendulum movement by the swinging and the putting in unnatural and unstable posture with the conventional typical putter to produce rotation of the golf ball. Further, the SSP of the present invention assures a golfer to execute better putting in more confidence and assurances because the structure of the SSP and the posture for putting reduce golfer's views differences between pre-examining and execution of putting, and resultingly, the differences between his estimated putting line that the golf ball would travel and the real putting result that the putted ball moves come to incredibly narrow, and the errors and the mistakes due to the differences and the disturbance in the past can be further decreased.

Furthermore, a golfer can practice putting and train his swinging with sufficiently securing visual competitive so that he can check his swinging better in direction or not and the reproducibility in direction can be highly increased. The skidding of the putted golf ball is decreased and its rolling is increased. In addition, the side swing putter of the present invention provides the advantages of correcting swing errors raised from golfer's habitual and stubborn swing posture and inducing the strike of the putter to the golf ball at the moment of putting at perpendicular to each other (right angle: 90°).

Particularly, the possibility of mistakenly strike on the lower edge in the past by use of conventional typical putter can be incredibly reduced or eliminated so that the momentary contact time at the hit moment of the golf ball with the head hitting surface of the SSP of the present invention can be extended, and even with minor slight swing mistake occurs, top spin can be produced and straight-lined directional movement can be improved. Furthermore, the resistance which the friction with the green grass may bring due to mistake at swing can be reduced and thus, the golfer can swing along the right direction and the hit golf ball can be proceeded along the straight line.

Referring to FIGS. 19 to 25, it will be explained in detail about the side swing putter (SSP) for golf ball putting while a golfer facing front and keep looking forward and putts a golf ball on the side of the ball according to an embodiment of the present invention, and hereinafter, the side swing putter (SSP) of the present invention may be noted as Look & Watching SSP. The SSP of the present invention is configured to add a second shaft 40 and a second grip 50 to a first grip 10, a first shaft 20, and a head 30, which are the components of a typical putter.

The second grip 50 is placed in the middle of the second shaft 40, and is configured for a golfer to be able to hold by his (or her) either one hand such that his palm of the hand is directed to face a first target direction. The first target direction means the direction which the hit ball is proceeding toward.

The first shaft 20 has the diameter equal to or close to that of the conventional golf putter. The first shaft 20 is located between the head 30 and the first grip 10, and specifically placed before and after the second shaft 40.

A second indicator line 21 is formed on the lower portion of the first shaft 20 as shown in FIGS. 20 to 22. The second indicator line 21 helps the golfer to see his swing accuracy visually when he swings a golf ball back and forth for putting on the side of a ball.

The head 30 is located at one end of the first shaft 20. On the putting surface of the head 30 is formed a reverse camber 31 having a predetermined angle (θ14) as illustrated in FIG. 23. The predetermined angle (θ14) of the reverse camber 31 is an inclined angle in the range of 1° to 3° with respect to a vertical line to produce top spin on the ball in order to enhance a straight-lined direction movement of the golf ball 200 being putted.

The predetermined angle of the reverse camber 31 may be very small, which is formed such that the upper portion of the putting surface of the head 30 is thick and the lower portion of the putting surface of the head 30 is thin.

As shown in FIGS. 23 to 25, a fixing point P1 is formed on the head 30 behind the putting surface of the head 30, and the first shaft 20 is fixedly positioned to the head 30 through the fixing point P1, which maintains a predetermined angle (θ13) with the head 30. As shown in FIGS. 22 and 23, a groove 32 shaped like multi steps in parallel are formed on the reverse camber 31 in order to produce top spin on the golf ball 200 by increasing its surface friction against the rotation direction of the golf ball 200 when a golfer swings and putts the golf ball 200 on the side of the ball.

The edge on the lower portion of the putting surface of the head 30 is made round in order to reduce putting errors which may occur by hit and impact on the edge of the head as illustrated in FIG. 23. An edge groove 32a is formed on the round-shaped edge of the putting surface of the head 30 with extended from the groove 32.

As shown in FIG. 24, weight distribution units 33 are formed on the back of the head 30 opposite to the putting surface of the head 30 having the groove 32 formed as multi steps in order to distribute its center of mass to both side ends of the head 30 and reduce the putting errors out of sweet spot. Also, the weight distribution as above helps for head swing perpendicularly (90°).

Further, an adjust weight 34 is formed on both side ends of the back portion of the head 30 in order to help correcting swing mistakes and to reduce the errors in swinging the putter to wrong direction incorrigibly and habitually.

The adjust weight 34 comprises a weight coupling part 34a formed on the back portion of the head 30, and adjust weight members 34 and 34b having different weight, for example, 12 g and 24 g, or screw of plastic dummy and selectively coupled with the weight coupling part 34a.

A first indicator line 35 is formed on the top surface of the head 30 as illustrated in FIG. 24 in order to visually guide a golfer the accuracy of the swing direction in training of swinging or in putting a golf ball in golf play games on the green. On the bottom surface of the head 30 are formed a plurality of blades 36 aligned in parallel with low height illustrated in FIG. 25 in order to reduce the friction of the head 30 with the top of the green grass in case that the head 30 of the putter comes to much contact with the grass on the green by swing mistakes, and in order to improve the direction of the ball travel as desired way of putting.

The second shaft 40 is located between the portions of the first shaft 20 below the first grip 10 and above the head 30 respectively, and formed to have a smaller diameter than that of the first shaft 20. The diameter of the second shaft 40 is in the range of φ5 mm to φ7 mm so that the second shaft 40 is inserted and held between forefinger and long finger or between long finger and fourth finger when the golfer holds and grips the second grip 50 having ball-shaped.

The side swing putter (SSP) of the present invention is shaped for a golfer to enable swing and putt a golf ball in more ease and with more comfortable position while he stands and keeps looking at the front toward the direction to a hit golf ball should proceed. Also, the second grip 50 is configured to have a ball shape as described above, which is easy for a golfer to enable hold the shaft of the putter and grip the second grip 50 more firmly with the palm of his one hand facing toward the direction of a target to which a putted ball should proceed and settle into, and enable keep watching and checking how the putted ball proceeds after swinging and putting.

The second grip 50 comprises a first stopper 51 formed on one side surface of the second shaft 40, and a plurality of second stoppers 52 formed on opposite the other side of the second shaft 40, a first hemisphere grip 53 having a first hole 53a which the first stopper 51 is fitted into, and a plurality of first nut insertion coupling holes 53b, a second hemisphere grip 54 positioning in opposite to the first hemisphere grip 53 and having a plurality of holes 54a which the second stoppers 52 are inserted into respectively and a plurality of coupling holes 54b, and fixing bolts 55 for coupling and fixing the two hemisphere grips 53 and 54 together when closely contact the first hemisphere grip 53 and the second hemisphere grip 54 together to the outer circumference surface of the second shaft 40 until to form a sphere shape and then, fix themselves to the second shaft 40 and be coupled to each other.

That is, the first hole 53a of the first hemisphere grip 53 is inserted into the first stopper 51 formed on one outer surface of the second shaft 40.
